An Introduction to STRATEGIC MANAGEMENT AND THE ROLES OF THE GENERAL Essay

An Introduction to STRATEGIC MANAGEMENT AND THE ROLES OF THE GENERAL MANAGER - Essay Example Strategic management takes account of the strengths and weaknesses of the organizations and prepares itself best in competitive arena by minimizing weaknesses and maximizing strengths. The human resource of the company is structured and inspired to achieve the objectives of the company. The role of the General Manager is that of a leader of human resources who guides and allocates the usage of other resources. Thus the role of the General Manager assumes critical importance in implementing the company’s objectives across various functional departments, and integrating the workforce to achieve the stated goals of the company by reining wayward behaviour and ‘self-direction’ to ‘shared beliefs’. This is achieved through development of communication channels, smooth flow of information across company’s structures, conflict resolution, and provision of creative latitude and development of a sound organizational culture. The General Manager keeps th e Board and the CEO informed about the progress and performance of the company. He/she is the vital link in vertical and horizontal communication amongst company’s stakeholders. Due to its strategic importance, sometimes the job of General Manager becomes extremely stressful.

Affirmitive Action initiatives Coursework Example | Topics and Well Written Essays - 250 words

Affirmitive Action initiatives - Coursework Example s owing to the fact that the US has become increasingly dominated by people from the Asian and Mexican decent that have dominated the work force in the past. This has made it increasingly difficult for companies to make out the individuals that qualify for affirmative action. This being said, I think that biracial individuals should be counted for Affirmative Action initiatives based on their lineage and simply not by looking at the color of their skin. This is because looking at the skin color can be deceiving. Secondly, it is important to look at the social status of the individuals. Some biracial individuals are well-off and may not be in need of the affirmative action. Biracial individuals should also be counted based on where they come from (Korgen, 1999). This is because some of them live in highly marginalized areas and are in dire need of the affirmative action within the work place. Finally, affirmative action should be based on the academic background of the individuals. Some biracial individuals are well educated and may not require Affirmative

Contemporary Issues in Business (Individual Report) Essay

Contemporary Issues in Business (Individual Report) - Essay Example Over long periods of geological time, the earth’s climate has been constantly changing in response to the tilt and shape of the earth’s orbit as it moves around the sun, the strength and intensity of the sun coupled with the composition of the earth’s atmosphere, the basic shape and position of the continents. There has been strong evidence that some human activities such as the use of fossil fuels are responsible for the constant emission of harmful greenhouse gases that are now causing an increase in the earths temperate in addition to other changes in climate (Richter 2010). Greenhouse emissions are currently projected to increase significantly within the next few decades which will cause an increase in global temperatures and subsequently put to great risk the human society and natural environment worldwide (Pedersen and Nordic Council of Ministers 2000). Climate Change and the Greenhouse Effect The temperature on the surface of the earth is largely determine d by the balance between the energy that is constantly re-radiated to space from the earth mostly in the form of infra-red radiation and the energy that comes from the sun which is seen to be in the form of visible radiation (sunlight). When the sunlight passes through the earth’s atmosphere, it has relatively very little warming effect but when it finally manages to come into contact with the earth’s surface, it warms it and the earth in turn warms the atmosphere by both convection and via emission of infra-red radiation which are absorbed by the greenhouse gases (R.I.C. Publications 2007). The greenhouse gases eventually return some of the infra-red radiation back to the earth’s surface which ends up further warming the earth’s surface. An analogy of this chain of events is often made with reference to greenhouses which generally allow sunshine to pass through their clear plastic or glass which in turns stop the heat that is inside the green house from escaping into the atmosphere and hence the use of the term â€Å"greenhouse effect† (R.I.C. Publications 2007). Fossil Fuels and the change in Climate System Fossil fuels are formed when the bodies of living organisms die and remain compressed and heated over extremely long periods of time to form natural gases, oil and coal. When burned, fossil fuels are seen to produce significant amounts of energy a factor which causes them to be considered as an extremely valuable energy source. However, the burning of these fossil fuels produces the emission of carbon dioxide, resulting in the introduction into the carbon cycle of carbon that would have otherwise still remained trapped in the earth’s geosphere (Downie, Brash and Vaughan 2009). It is currently estimated that the burning of fossil fuels is responsible for adding to the atmosphere an estimated 3.2 billion metric tons of carbon. Because the earth’s carbon cycle is unable to absorb all of this excess carbon bein g released into the atmospher

Global Environmental Issues Essay Example for Free

Global Environmental Issues Essay Global environmental issues, such as climatic change, global warming, pollution, species extinction and destruction of tropical rain forests hold unique place among other major international problems as it is one area that has transformative, comprehensive and long term impact on the future of entire world. For over a decade now the subject of these issues have become the common platform for intellectuals citizens, scientists, social organizations, and political and economic leaders from different parts of world to converge, assess and determine the possible ways to contain and mitigate its threat, that poses an unprecedented risk to the functioning and perhaps very survival of humanity. Climatic change, rain forest destruction and global warming are all interrelated issues, borne from same cause of increase in population and consumption. The empirical instances of these problems have been already factually corroborated in late in 1980s and early 1990s (Paterson, 1996). The years since 1987 started to show the veracity of these predictions as global average annual temperature soared higher every passing year and 1998 became the warmest year in the recorded years. More ominously, the second and third most warmest years in recorded history were 1995 and 1993, confirming to scientists, environmentalists and people that the rise in global temperature was not a sudden phenomena, or an aberration, but a systematic process that would compound in the absence of any effective policy and action (Johansen, 2002). Meanwhile, the destruction of Amazon and African rain forests have further compounded the problem, causing the environmental conditions to deteriorate more rapidly. Issues of climatic change and global warming have assumed international proportion as people have started to realized that the warming is a consequence of the largely unstructured paradigm of development, consumption, and growth followed over past 200 years, a problem that has been deeply embedded in the socio-cultural and economic system of the world (Uzawa, 2003). Despite the fact that there are many people over the world who would readily associate United States as the whole sole perpetrator of emission of greenhouse gases and global warming, United States has been among the leading campaigners to instituting policy change and corrective actions on the most comprehensive and global level to tackle the problem. The threats arising from global warming are bound to affect US’ economic and public interests with same intensity as they would affect that of any other country (Fleagle, 1994). Changing sea-level, intensification of storms, and climatic change have presented real threats for the United States and it is pressed for a domestic as well international solution (Uzawa, 2003). The problems with US are that its complex economic interests, industrial structure and societal framework doesn’t allow it to implement any drastic measures that may force a possible economic collapse (Victor, 2001). Under these strenuous complications, the US government is trying to come up with a policy for large scale institutional change and economic streamlining that aims to incorporate environmental costs as part of the economy and the society.

Comparative in-vitro Quality Evaluation of Cephalexin

Comparative in-vitro Quality Evaluation of Cephalexin A COMPARATIVE IN-VITRO QUALITY EVALUATION OF DIFFERENT BRANDS OF COMMERCIALLY AVAILABLE CEPHALEXIN IN KARACHI (PAKISTAN) SHAHBAZ AHMED NOOR Abstract: Approximately 600 generic drug applications (ANDAs) approved each year, 65 % of prescriptions are for generic indication from oncology to insomnia without repeating clinical trials .Every generic molecule references a previously approved drug. Cephalexin Monohydrates was first sold by Eli Lilly in 1972. The availability of many brands of cephalexin 500 mg capsules in Pakistan market today place healthcare providers in a difficult situation of choice of a suitable brand or alternate use possibility .The objectives of this study was to carry out pharmaceutical equivalence studies on different brands of cephalexin 500mg capsules available in local market of Karachi. The invitro parameters include all pharmacopeia and non-pharmacopeia tests that were dissolution rate( in 0.1 N Hydrochloric Acid at 37 à ¢Ã‚ Ã‚ °C ) ,weight uniformity , disintegration time , moisture content ( with the help of suitable Karl Fischer Titrator ) , appearance (observed physically before and after opening of the shell) , Identification ( compare manually retention time in HPLC chromatogram of sample with chromatogram of reference standard ) and HPLC assay of cephalexin (as describe below based on HPLC assay method AM1172) were also analyzed. Along with the inappropriate use of antimicrobials drugs, substandard antibiotic medicines may also contribute in resistance development against susceptible organism. The study will be helpful to evaluate the efficacy and justification of generic substitution of cephalexin 500 mg capsule brands in Karachi (Pakistan) INTRODUCTION: Antibiotic, being the wonder drugs, are widely prescribed in the developing countries. In reality, 25 to 40 % prescriptions contain one or more antibiotic (Public Sector studies, 1990-1993) Antibiotic resistance can be developed through its wide and inappropriate use without following any standard guidelines. This Alarming situation has been addressed in several scientific journals (Glass et al.,1980; Farrar , 1985; Saha et al., 2003;Lina et al.,2007;Hassan et al.,2009) Post –marketing surveillance include complete procedures undertaken to obtain more data and information about a product after it had been granted marketing authorization and made available for public use, this data used for product improvement ,development standard and regulations. Regulatory agencies rely on limited information get from clinical trials and from scientific literature as guide to granting to marketing authorization of medicine for public use. Post-marketing surveillance of approved dosage forms is to assess the quality, effectiveness and safe use of medicine to large population. To Assess the standard of a product, invitro dissolution test is widely used because , for any solid dosage forms, gastrointestinal absorption first requires dissolution of the tablet or capsules that librates the drug into solution (Goodman Gilman`s –The Pharmacology basis of Therapeutics,2006) The dissolution characteristics of a drug from the dosage form depend on many factors including its formulation and manufacturing process (Augsburger et al., 1983). Cephalexin Chemically, Cephalexin is {(6R, 7R)-7-[(R)-2-Amino-2-Phenylacetamido]-3-Methyl-8-oxo-5-thia-1-azabicyclo [4.2.0] oct-2-ene-2-carboxylic acid monohydrate} is a first generation cephalosporins for oral administration which is bactericidal, and mainly used in the treatment of various bacterial infections caused by gram +ve and gram -ve microorganisms. .( Ralph R et.al 1970).Excellent oral absorption and lack of serum binding of cephalexin compensates significantly for the lower in vitro activity.( Warren E. Wick et.al 1967). Antibacterial Spectrum of Cephalexin: Cephalexin appears to be a highly effective antibiotic. It possesses the qualities of rapid oral absorption, production of high drug levels in the blood and urine, and near absence of side effects. It is effective against infections due to gram-positive cocci infections, with the exception of Enterococcus, and for most infections caused by E. coli and Klebsiella. It is useful in the treatment of a wide variety of infections in infants and children, and particularly valuable with susceptible infections in patients who do not require parenteral antimicrobial therapy. (R.C. Rudoy, M.D.1977) The first-generation cephalosporins, epitomized by cephalothin and cefazolin, have good activity against gram-positive bacteria and relatively modest activity against gram-negative microorganisms. Most gram-positive cocci (with the exception of enterococci, methicillin-resistant S. aureus, and S. epidermidis) are susceptible. Most oral cavity anaerobes are sensitive, but the B. fragilis group is resistant. Activity against Moraxella catarrhalis, E. coli, K. pneumoniae, and P. mirabilis is good (Goodman Gilman`s –The Pharmacology basis of Therapeutics,2006) Literature Survey: A ) Helio et.al in 2007 In this study, they observed the antibacterial spectrum of the orally prescribe cephalosporin (cefaclor, cefdinir, cefpodoxime, cefprozil, cefuroxime axetil, cephalexin) and amoxicillin/clavulanate, as these drugs were widely prescribed for community acquired respiratory tract infections. Narrowest zone was of Cefaclor and Cephalexin against evaluated pathogens. Overall, the 3rd Generation of cephalosporin is more useful in respiratory tracts and other infections when administered orally, as compared with older generation or amoxicillin alone. B ) Chalermporn et.al in 2005 ,they studied for rapid and sensitive identification of cephalosporins drugs such as cefoxitin , cefazolin , cephalexin, cefadroxil , cefaclor and cefoperazone, a flow injection (FI) method was used. This method was applied successfully for the identification of cefoxitin, cefazolin, cephalexin, cefadroxil , cefaclor and cefoperazone. The method was successfully applicable for the identification of cefoxitin ,cefazolin , cephalexin and cefadroxil in the pharmaceutical formulation with a sample throughput of 90h−1. C ) Rist et.al in 2002, they studied on Oral Cephalexin compared with mupirocin calcium cream with respect to safety and efficacy in secondarily infected eczema treatment. The adverse effect most common , they observed was diarrhea and nausea, effective clinical dose of mupirocin cream was apply three times daily as compared to cephalexin orally four times daily in secondarily infected eczma as topical regimen was preferred by the patient that enhance patient compliance. D ) Lennart Venemalm et.al in 2001, worked for the diagnosis of allergy against ÃŽ ²-lactams, prazinone-polylysine conjugate was able to bind with antibodies IgE in sera from patient with suspected allergy to cephalosporin’s. This information may be used for diagnosis of allergy against ÃŽ ²-lactams. E ) Yagnesh P. Patel et.al in 1998 They studied, modern data on the isocratic assay of five antimicrobial drugs ,five different assay were performed to one single report, antibiotic used in this study were cephalexin and cefaclor (cephalosporin’s), isoniazid and pyrazinamide (anti-tubercular drugs) and minocycline (tetracycline series) . Overall they concluded that any one of the drug could be used as internal standard for other four drugs. F ) Godfried Owusu-Ababio et.al in 1995 Sustained release of cephalexin ciprofloxacin, was evaluated in open chemostat sytem. They concluded that chemostat system is convenient for sustained release drug testing as a function of formulation parameter. G ) Anne H. et.al in 1992 In this study, the Cefaclor uptake was observed concluded that it was sodium-independent, but proton-dependent and also the energy dependent , dipeptides inhibited uptake of ÃŽ ²-lactam antibiotic but amino acid had no effect on uptake , the overall data from this study concluded that a single proton-dependent dipeptide transport carrier support the orally absorbed antibiotic uptake into Caco-2 cell shows correlation for the use of Caco-2 cell for cellular model of the intestinal proton-dependent dipeptides transporters for study purpose. H ) R. Wise et.al in 1991 Cefibuten, invitro activity was studied against 572 bacterial strain and was compared with orally administered ÃŽ ²-lactams. Cefibuten being more active against Enterobacteriaceae. There was less activity of cefibuten cefexime against Staphylococci and reduce activity against streptococcus pneumonia. I ) Luis J et.al in 1982 They studied, Acid degradation of cephalexin in presence of formaldehyde, produce 2-Hydroxy-3-phenyl-6-methylpyrazine.In 5M HCL this product gives well defined reduction wavelength with half wave potential of -0.45 vs. SCE. The wave was diffusion –controlled irreversible, linear relation with the cephalexin conc. was shown with diffusion current and cephalexin in plasma can be determined through it. J ) Ralph R et.al in 1970 They performed to detect various crystal forms of compounds, the employment of solubility versus solvent composition diagram. This appears to be a convenient sensitive method for detecting new crystalline phase. Aim of Project: The objective of this study is to carry out pharmaceutical equivalence studies on different brands of cephalexin 500mg capsules available in local market of Karachi. The invitro parameters include all pharmacopeia and non-pharmacopeia tests that are dissolution rate, weight uniformity, disintegration time, moisture content, appearance, Identification and HPLC assay of cephalexin will also be analyzed. The susceptibility test of drug will also be evaluate by ICLS ( Formerly NCCLS ) Reference Disk Diffusion (Kirby-Bauer) method against different clinical isolates of Staphylococcus aureus (03), E. coli (03), Klebsiella pneumonia (03), Pseudomonas aeruginosa (02), Importance of study: This is a growing concern that if a health care provider, providing the substitute of the generic is also the Bioequivalent. For the health care providers to use these brands interchangeable, the bioequivalence of these brands have to be ascertained, this mean that there should be continued post marketing monitoring of the medicines. EXPERIMENT: TESTING PROCEDURE: Test # 1: Cephalexin Monohydrate (As base): Procedure: Perform HPLC assay of Cephalexin as describe below based on HPLC assay method AM1172. Test # 2: Identification: Procedure: Compare manually retention time in HPLC chromatograms of sample with chromatograms of reference standards. Test # 3: Moisture Content: Procedure: Three times separately the moisture content in the powder of the product with the help of suitable Karl Fischer Titrator will be determine and then calculate their mean. Test # 4: Appearance: Procedure: From the 20 capsules take 10 capsules and observe physically before and after opening of the shells. Test # 5: Weight Variation: From 20 capsules take 10 random capsules from composite sample and note individual weight of filled capsules. Calculate their average, minimum, maximum and COV%. Test # 6: Disintegration: Procedure: Prepare a 0.6% v/v solution of HCl (Add carefully 16.2ml of 37% HCl into 500ml of distilled water and then make the solution up to 1000ml with distilled water) and fill the vessel of a suitable disintegration test apparatus with this solution up to recommended height. Maintain the temperature between 35  °C and 39  °C. Place 1 capsule in each of the 6 tubes of the basket and run the equipment. Start the stopwatch and note the time when all capsules are disintegrated. If 1 or 2 capsules fail to disintegrate, repeat the test on 12 additional capsules. The requirements of the test are met if not less than 16 of the 18 capsules tested have disintegrated. Test # 7: Dissolution: Procedure: According to USP 2007 page # 1691.

The Gap Between Rich and Poor Essay example -- Poverty Poor Essays

The Gap Between Rich and Poor As Christmas time approaches, many Americans start to get excited about returning home to all of the familiar festivities. They imagine the smell of the Christmas tree mixed with the aroma of apple cider or think about all of the Christmas specials on television that they will watch. They can not wait to relax in front of the fireplace with their families and to open all of the Christmas gifts piled under the tree. On the other hand, more than half of the rest of the world will not be having the kind of holiday with presents, fireplaces, and television specials that most Americans are used to. In fact, the money U.S. parents spend on Christmas presents alone this year will probably be more than the annual income of over half the worlds population. It is heartbreaking. Our world is essentially divided into two sections: rich and poor. Unfortunately , the majority of people are poor. Each society has certain attributes that are part of its culture. Richer countries are literate, industrial, overweight, overfed, and comfortable. Poorer societies are illiterate, under-developed, hungry, malnourished, and struggling to merely survive. There is a very large and uneven gap between the rich and the poor. This gap is a very real thing. Poverty is a reality that exists for most and effects them every single, waking day of their lives. It is a reality in which children die because their parents could not afford penicillin. People live in small, one-room shacks in groups, of ten with no running water and little food. A bathroom for them is a large hole in the ground. Poverty is a real struggle that’s purpose is to merely survive. This type of poverty did not always exist. Before the Industrial R... ...ndustrial capacity, technology, and infrastructure to compete with the industrialized countries, which have been honing their economic might for over a century. All in all, the problems in the other world in terms of oppression are too great to fathom. It is sick that a minority of the population can cause such agony and deprivation to their own human kind. One of the biggest problems in resolving the problem is that most Americans are completely naive and oblivious to this great oppression that merely continues to get stronger. This year, when all of the Christmas festivities start, maybe some will be a little more humble and remember the part of Christmas called giving. Help has to start somewhere. Individuals can do a tiny bit for maybe one family this Christmas. God willing, the spirit will spread, and the other world might some day find a glimmer of hope.

Population…A Problem That Most of the World Simply Disregards Essay

Population†¦A Problem That Most of the World Simply Disregards There are over Six Billion people inhabiting the planet earth today and that number is growing. â€Å"In the six seconds it takes you to read this sentence, eighteen more people will be added† (Ehrlich 9). The total population of the World, projected on October 23, 2001 at 6:28:09 pm GMT was 6,181,600,089 people (U.S. Bureau of the Census). Each hour there are 11,000 more mouths to feed; each year more than 95 million. Nevertheless, the world has hundreds of billions fewer tons of topsoil and hundreds of trillions fewer gallons of groundwater with which to grow food crops than it had in 1968. Millions of people every year are dying because they are not getting enough food. You see the advertisements, and television programs showing the starving children in Africa and other developing nations: their pleading eyes with helplessness. National Geographic shows the images of tropical forests on fire, beaches strewn with garbage and sewage, and refugee camps filled with hungry people unable to produce enough food because there aren’t enough resources to support the world’s growing number of people. These problem do not only exist in far away countries†¦drive in any large city, you will be overwhelmed with the number of drivers filling the freeways, grid locked any time of day. Visit downtown and see the hundreds of homeless people on street corners, and lined up around the block in front of the shelters for a warm meal. Our news is filled with the nation’s crime, violence, and drug abuse. Global warming is old news, but it is killing us, our ocean level is rising, and our crops are going dry. We are cautioned about the AIDS epidemic because it is everywhere,... ...t needs to understand the problem at hand, and recognize its far-reaching consequences.

Playground Payback

In the far hills of North Carolina, there was a school called Blue Creek Elementary. It was half a century old, and you could definitely tell. The yellow stained walls of the classrooms had marks from play dough and crayon. The chalk board was cloudy with dust from a thousand words before. The smell of each room was basically the same, chalk clappers and weak tea, and the colour of autumn leaves was present throughout the year. It was January 2002. The climbing frame in the playground was rust incrusted, and the paint was crumbling off, but still was in use as if it was new everyday. No one child was dissatisfied with their school life, they could see nothing wrong with the way they were ruled, the rota they followed or the order they had come to be in for so many years. They were treated equally as each other, by the council they had elected. Every new school year in September there would be an election. Any volunteers would under go a number of campaigns to become the new king of the playground. For the last three years no one had been a match for King Rob. In the last year no one was even prepared to challenge Rob Jenkins, but it wasn't because they were scared, no, quite the opposite. There was nothing wrong with the way he ruled them. He took care of them; he was their agony aunt to their problems, a King Solomon in his own day. He brought them new games, fought for new rights and changed the word recess itself. But all this was about to change, something, or someone was just around the corner. PJ, Felicity, Pikes, Jennie and Russ were playing kickball, a game Jennie ruled without a doubt. It was known to everyone that they were an untouched gang. They had been for years, what seemed like friends forever. PJ was like the leader, although he claimed he didn't know it. His round pot belly and backwards baseball cap were historic trademarks in the playground's history, almost hereditary, as his father was also seen wearing them in his time at Blue Creek. Felicity was thought of as â€Å"the brains†, and she liked it like this. She was studying at a 10th grade level, four years ahead of the rest of her class, but resisted being moved up away from her friends. She had long brown and unruly hair, which she only ever wore up when in P.E, the only school subject she detested. Unlike Felicity, P.E was the only subject Jennie didn't hate. She was an unlimited fan of wrestling, and never once considered herself a girl, apart from when in the presence of her parents. It was the first week back from Christmas break, and there was already a new kid. His name was Prince Dartmoor. He had black, short and curly hair. His face was coloured, and he wore a red white and blue Globetrotters uniform. He had white sneakers, and was bouncing an orange basketball signed by Michael Jordan. It didn't take long for a disorderly crowd to form around him. They were watching something. The gang stared in amazement. Prince was standing in the middle of the playground, at least twenty five yards away from the basketball hoop. â€Å"Ya don't think he's gonna try for do ya?† questioned Russ. He looked at PJ with a sense of honour. He felt that PJ was all knowing all seeing; he would have the answers to anything and everything. â€Å"Nah! Look at him! His stance is all wrong and his arms are flying everywhere, there's no way he'd even come close to-â€Å", PJ halted. Just at that moment, Prince threw the ball with all his might. It climbed the air like a mountaineer, and flew down gracefully, landing through the hoop. For what seemed like a lifetime, no one made a sound, and then out of the blue, the crowd burst into a thunderous applause. The gang was in awe. Even PJ was stunned. Prince looked at PJ with familiarity. PJ didn't know how, but Prince knew who he was, and it definitely seemed that he was planning something. Meanwhile the crowd was dying down, though kept up their pleasure with Prince. He was stepping up onto an overturned box, and someone handed him a loudspeaker. â€Å"Ch-â€Å", he began, but was automatically put off with the alien effect sound that was coming out of the loudspeaker. He switched a button, and restarted, â€Å"Children of Blue Creek playground,† his voice was loud and unyielding. No one made a sound. Everyone's eyes were on him. â€Å"I have down a lot of research before transferring here. I had to find a school where my services are needed, and I have found no other group kept so much in the dark as this one; I am here to put a stop to the treacherous behaviour your ruler has been withstanding. He has made you his servants, while calling you equal. He has held you back from rights you so truly deserve and said you have everything. Listen up, I have someone here to tell you something† Prince finished with a look of confidence. A small, shaking figure was brought through the crowd. His face was irregularly pale, and his black hair was on end. â€Å"My name is Kyle. I go to Belle Fork Elementary, King Rob's cousin used to go there. He ruled the playground there too, up until 6th grade in his fourth year as king, he turned on everyone. No one had seen it coming, but we found out he'd been doing it slowly, making us think it was for our own good.† He halted. â€Å"What he do?† shouted someone from the crowd. â€Å"He changed the rules; slowly as I said, but changed em. First we couldn't have cookies anymore, he'd confiscate em, then we couldn't have snacks altogether, and then†¦ he took away the kick balls. Even if they was our own from home! He'd taken all our games, until there was nothing left. Recess was just kids sittin' around the place. No one was even allowed to speak! And if someone broke a rule, they'd get taken away, no one ever saw Timmy Reynolds again!† Kyle looked in despair at the crowd. They just stared at him, too scared to speak. â€Å"I think everyone here will agree with me that something has to be done before King Rob follows in his cousin's footsteps. My research has told me that his father and uncle did the same thing when they were in their fourth year, and their father before them! I propose we revolt, stopping this cycle dead in its tracks! Now who's with me?† he shouted more confident than ever. And then what followed was a colossal roar of approval, and that was that. The reign of King Rob had definitely come to an end. The crowd followed Prince, half stirred up in the confusion, half hungry for revenge. They came to the Jungle Jim Palace. Prince shouted up to King Rob, â€Å"Rob, your people are in total agreement. You are being exiled! I am a civil kid, so I'll give you 'til next recess to get outta our playground!† the crowd screamed with excitement. PJ, Felicity, Jennie, Pikes and Russ looked at each other for reassurance. They knew, even if they were the only ones who did, that th is was not a good idea. The gang walked away from the mob and came to their territorial kick ball field. PJ turned to the others, â€Å"We gotta something.† â€Å"But what can we do, you saw em out there! There's no way we're ever gonna change their minds!† laughed Jennie. She was stubborn, more so than PJ, so he couldn't argue with her usually. â€Å"It's like our pretty rainbow of life is being painted with black ink, and we're choking helplessly† Pikes recited. His love for poetry never stood down, even in the face of destruction. â€Å"What are we gonna do when it all goes wrong?† Russ panted. He took a deep breath from his asthma inhaler and looked at it panicking. â€Å"I could loose my inhaler! I could end up in hospital! The sky could fall down and we'd all be crushed and go under ground forever and ever and ever and ever an-â€Å", Russ was hit over the head by a scowling PJ. â€Å"Sorry!† Russ twitched. â€Å"I may have a suggestion to our current predicament.† Felicity joisted her words together and flew them out perfectly as ever. â€Å"Now as Jennie said, there is no possible way to overthrow the minds of the children. They are under an exciting grasp, and though deep down they may know it is wrong, they can't consciously tear away from it. But there are definitely some exceptions to this hypnotic phenomenon, us being one, and of course another being, as much as I hate to say it†¦ the Jaimes.† She gave a pause to invite any protesters. â€Å"Oh no! Don't even think I'll ask for their help again! Never! Not in a million years!† Jennie was convinced that the Jaimes were total hypocrites. All they did was wear make up and talk about boys. They were totally against everything she believed in, especially her tom boy criteria. â€Å"I'm sorry Jennie, but it's the only way. They have an almost never ending access to a boys mind, and if we've got to get rid of this Prince, we need all the help we can get.† Felicity stood with authority. Jennie finally, yet dejectedly agreed, as did the rest of the group. The Jaimes Clubhouse was in a large underground shelter they had paid the digger twins to build two years before. Though the outside was plain and misleading, the inside was an interior designer's heaven. There was a lilac carpet, and a purple fur rug. The walls were bright pink, and drapes were icing blue. There was a dark blue sofa, and a mahogany coffee table. The Jaimes were sitting on the sofa when the gang walked in. â€Å"What are you doing here?† said Jaime 1. She had long blonde hair and green surly eyes. She wore a pale blue suit and black soft heels. Although the Jaimes considered themselves equal, they had to distinct each other somehow, and so they were numbered in age order. PJ looked at them with slight pity and disgust. â€Å"We, and don't laugh when I say this†¦need your help† the Jaimes ignored his request and laughed in his face. â€Å"Why would you need our help?† questioned Jaime 3. Number 3 had dark curly hair and was coloured with brown eyes, but had a nicer smile than number 1. She was wearing a yellow suit, only differing number 1's in colour. PJ noticed that they always wore the same thing but in different colours years ago, so he wasn't taken back. Felicity took the role of explaining their problem to the girls, while the rest of the group hoped for a good response. The Jaimes sat and listened carefully, even number 1 didn't speak until Felicity had finished. The Jaimes had been inside while Prince's debut had taken place, so everything was news to them. At the end, their faces looked shocked. Number 1 spoke first. â€Å"So what do you want us to about it? I mean, we are obviously concerned, but how are we supposed to help?† it seemed that they were genuinely trying to help, for the first time ever in PJ's knowledge. â€Å"That's the genius of it! Everyone knows that you guys are at least two years ahead of your age; you act like you're already in high school. Well it seems to me that this Prince guy is at the same level as you, so it wouldn't be a misconception if we thought it was possible†¦for you to, how can I put it, distract him!† Felicity explained with appropriate verbal skill. â€Å"You want us to flirt!† Number 4 caught on. She was wearing the green variety of the suit. â€Å"That's one way of putting it, yes!† Felicity looked at her, expecting disapproval. â€Å"Now you're talking! A way we can put all our uses together! Flirting and lying!† Number two was obviously happy with the proposal. â€Å"Great1 and while you create a few weeks distraction, we can look into Prince, not literally of course! We'll investigate his past, and come up with some proof to convict him of†¦Ã¢â‚¬  Felicity thought, â€Å"Something we don't know yet!† The weeks went on, and as far as the gang could tell, Prince was enjoying the act of the Jaimes. Prince had come to be the leader of the playground. He resented anyone proclaiming him to be a king. He said they were all equal, even him. He had produced a short list of laws, which he thought were important if they were to sustain equality, they were: never to downsize another playground associate, always to put others first and never to be selfish. The children of the playground had started up a little chant, and when he heard this, he decided to make it into a regular native song. Whenever there was a meeting, which there frequently was, it would begin with verses of this song, which Prince called Blue Creekers of America. It was sung to the tune of If Your Happy and Your Know it, and went like this†¦ From the Ball field to the swing set we are free, All the way across the playground we are free, When they try to tell us different, We just turn around from infants, If you're a blue creeker than shout out we are free. Don't ever think you'll ever be alone, Think of the playground as your very happy home, If you ever need a hand, Then Prince will understand, If you're a blue creeker than shout out we are free. If you're a blue creeker than shout out we are free! The gang wasn't having much luck looking for evidence (except they knew that kids toys and candy were going missing, even someone's portable television), so PJ, Russ and Pikes decided to take it into their own hands one Saturday night. They snuck out and met at City Hall. Pikes' dad worked there, so it was easy to get the keys. They were all wearing black, navy blue or any other dark colours, though none of the burglar clothing, it would be extremely suspicious if they were seen. They crept into the hall, and saw a door labelled â€Å"Staff only†. This was it. Pikes pulled out a set of keys, and tried three before finding the right one. They opened the door, looking out for any night watchers. They slowly and cautiously walked in the room. There were rows of filing cabinets with letter in alphabetical order above each one. They found row D. â€Å"Dakota, Daniels, Darter, Dartmoor! Got him! Prince Dartmoor. He used to go to Belle Fork. But there's no record of him before 1999† whispered PJ. He couldn't help but feel familiar with this school. â€Å"Belle Fork? That's where King Rob's- Rob's cousin went† noted Russ. He was confused, as were the others. If they went to the same school, why would he need Kyle to tell the story, unless, he was just a pawn in Prince's game play, and that would mean the story wasn't true. They decided to investigate further. They found J for Jenkins, and soon found Rob's dad's and Mum's files. They looked under siblings, and this is where it got interesting. They didn't have any. Rob didn't have a cousin, and the gang had found the evidence they needed. Suddenly, the boys heard a noise from outside the room. It was a guard. They looked hard for a way out, and came to a window. They looked at Pikes. His round chubby body wouldn't fit through that window if a shark was chasing him. â€Å"Go! Take the files! It's the only way!† Pikes forced them. â€Å"But what about you?† Cowered Russ, already hoisting himself up to the window. â€Å"I'll face the consequences alone! Everything comes at a price and this is ours. I'll be grounded for sure, but that's something I'll allow for the sake of the playground, now go!† Pikes courageously whispered. PJ nodded, and within thirty seconds of hearing the guard, PJ and Russ were outside. As they ran with the files tucked in the backpacks, they heard someone shouting, and knew Pikes had been found. On Monday at school was buzzing. The girls had been told to meet PJ, Pikes and Russ in the Jaimes clubhouse, with the Jaimes present naturally. The boys came in a few minutes late, but with plenty of time to spare before the first lesson began. They should them the files, and explained thoroughly what had on the Saturday night. The girls were immediately excited, and were mentally prepared for the removal of Prince. â€Å"Pikes, what did your parents say?† asked Jennie. â€Å"Oh I'm just grounded until I'm fifty. My dad says I could have got him fired, but I think he's just trying to scare me.† Pikes didn't sound his usual self. He seemed down, but was still anxious to get this thing going. The gang and the Jaimes racked their brains to form a plan but finally agreed that one was solid just as the bell went. The playground emptied, and the gang left separately from the Jaimes so as not to cause suspicion. The rest of the morning was spent making preparations. Jaimes 1 and 2 ‘distracted' Prince and the rest snuck around, and secretly spoke to kids they thought were suitable for certain†¦jobs. Pikes and Russ had a very important thing to do. It was morning recess. They went to a wooden gate and heard screams of terror and playful games. They walked through the gate, and entered Kindergarten Territory. They trekked passed the mass of wresting toddlers and painted tribal faces until they got to the Kindergarten King. His name was Lyle, but was called Tootoodyna in a mark of respect. Tootoo was short and fat, with red long hair. He, as the others, had clannish markings on his face, a beaded necklace and wore a grass skirt. â€Å"Morning your highness.† Greeted Pikes. He was well-known to Tootoo, and had been named his big kid friend. â€Å"Tootoo happy to see you big kid friend. Do you want favour?† Tootoo's language was primal, but understandable. â€Å"Yes. The big kids need your help.† Pikes began to explain the plan to the Kindergarten King, and Russ helped fill in things to. After a while, King Tootoo agreed to the plan with ease, and settled terms with the boys. The rest of the morning ran smoothly. The gang and the Jaimes acted normal, not doing much work with the exception of Felicity obviously. They were apprehensive, yet wanted it all the same. They wanted it over. They wanted things to go back to normal. Most of them were wondering what PJ had done. He had told them he had to do something at morning recess, and snuck out of school to do so, but when they asked what it was, he just smiled and said, â€Å"You'll find out.† Lunch came. The cafeteria was almost silent. Most because they could sense something was up, but some because they knew what was up. The gang left the cafeteria ten minutes after entering, and waited for the rest to follow. The gang knew that Prince would be sitting on the Jungle Jim Palace. He had forbidden anyone to touch it, including himself. He said it was a historic figure, one to remind them of the reign of King Rob. Two bodyguards were surveying the entrance. â€Å"We got it!† said Jaime 4 with pleasure. PJ nodded and smiled. The gang hid behind a bush, and watched the Jaimes bring the guards into the clubhouse. It was clear. The playground was starting to fill up by now. It was the perfect time, and there was no going back. PJ lead them to the palace. A few kids saw him and gathered round. What they'd been sensing, this was it. As the gang climbed up, more people gathered round, though no one was saying anything yet. When the last was in the palace, Jaime 3 came out. She spoke to the crowd in a quiet and calm yet commanding voice, â€Å"you have to make sure that Prince doesn't know you're here. Don't make a sound. You'll find out something you deserve to know, just as long as he doesn't think you're here, understand?† â€Å"Why should we listen to you? Prince has done nothing wrong† said one weasel like child. â€Å"Then it won't matter if you hear what he has been doing, if there's nothing wrong with it, like you said. Now go round to the back. We rigged a cup and string phone so you'll hear everything, but when you get there someone will be waiting. When you see them don't make a sound, they're important in all this, and you'll probably change your mind about them soon enough.† Jaime 3 instructed. They did as they were told, and as she said there was someone waiting. King Rob. A few of the crowd opened their mouths, but then remembered Jaime's words and didn't make a peep. They listened through the phone, and recognized the gangs and Prince's voices. â€Å"What are you doing here?† Prince asked angrily. â€Å"Could ask you the same question† replied PJ. His confidence astounded even him and especially Prince. â€Å"We know what you're up to. We know you made up that story and we know what's in this box right here† PJ stepped forward pointing to a large oak toy box, and opened it. There were all of the missing toys and candy. Prince stood there, stunned. He'd been found out, but wasn't going down without a fight. â€Å"Oh yeah, well who cares, you found me out, but as far as those idiots know, I'll tell em you took their stuff, and they'll believe me too, gullible and stupid. They follow my every move and guess what? There's nothing you can do about it!† Prince grew an evil smile. â€Å"Wanna bet?† King Rob entered the room and snatched the evil smile right of Prince's face. â€Å"You know as well as I do that I don't have a cousin, and yet you paid off some kid to lie about it. How much did you pay him? Ten, twenty bucks?† â€Å"Fifteen, but that's not the point. The point is, no one's gonna believe an outlaw and a gang of self righteous twits?† Prince felt safe again. There was no way they'd stop him now, was there? PJ picked up the box, took it to the balcony, and tipped out the contents, but holding the television. Prince was curious. He walked out onto the balcony, and saw the children of the playground listening to every word he'd been saying. â€Å"Fine. So you know. I applaud you all. Good job. But guess what Rob, you may have got out of this one, but I'll be waiting. Every move you make, every step you take I'll be ready to-â€Å"Prince was stopped dead in his tracks. The bodyguards walked up to him and dragged him towards the principle's office. â€Å"But why'd he do it PJ?† shouted someone from the crowd. â€Å"Rob, o you remember the name Jack Hollows?† PJ asked. â€Å"Yeah, he was my best friend up until 3rd grade, when he-â€Å", Rob paused, â€Å"he swore he'd get me back after I pulled down his jeans in the school play.† Rob had had a break through. He knew what was going on. â€Å"Pikes, Russ and I snuck into City Hall on Saturday night. We found out that Prince had lied about that story. Rob hasn't even got a cousin. Then we found out about Prince. There was no record of him before 1999. Then this morning I went home and searched his picture on City Hall records internet. They only give you their name of course, but that's all I needed. It came up with two records. Prince Dartmoor 1999 to present, and Jack Hollows 1991 to 1999. He changed his name right after the play incident, so he could get his revenge without a trace.† PJ gave the crowd a few seconds to mull over the information they had just been given, and then spoke once more, â€Å"So I ask you, are you regretful? Are you sorry? But most of all, do you want King Rob back?† the crowd gave no pause, just a dramatic, deafening â€Å"YES!† Prince (or Jack) was expelled from Blue Creek Elementary for stealing. He and his family moved to Alabama. King Rob was restored to his throne. The Jaimes were given luxuries to go in their clubhouse. The gang were labelled playground heroes, and Pikes was given an honorary stationary kit because of his bravery in City Hall. As for PJ, he was given the job of Royal Assistant. He monitored Jack's movement in Alabama, and checked out any new kids. Blue Creek Elementary was back to where it started, but with more trust, guidance and hope for the future- High School.

Letter of Advice Essay

I would like to start out by saying congratulations on your recent engaged and heard you are looking for some advice for your relationship. I would like this opportunity to tell you more about the following throughout the letter. Frist I will describe the process by which self-concept is developed and maintained. Second I will give you some strategies for active, critical, and empathetic listening. Third, Then we will discuss how words have the power to create and affect attitudes, behaviors, & perception. Fourth I will define emotional intelligence and its role in effective interpersonal relationships. And last but not least Fifth we will discuss how self-concept and defensive and supportive messages and behaviors create positive and negative communication climates. So, first off, it has been studied by many philosophers that self-concept starts pretty much at birth. Your self-concept is what people around you tell you about yourself and it is your outlook on all of your own attributes. Your self-concept usually stays with you for the rest of your life, it all depends on you. If you have a high self-concept then the people around you will see how you feel about yourself, and treat you as how you feel, well most of the time they will. The people around you can see how you feel about yourself by your body language and how you carry yourself, it is maintained throughout the rest of your life as long as you keep feeling good about yourself. If you have a low self-concept and the people around you have done nothing but put you down all of your life, there is a good possibility that you can bring that low self-concept into your relationship and bring you partner down with you. It could also cause a whole lot of stress on you  relationship. So try to make sure that if you have low self-concept work on bringing that up about yourself and know that YOU are the one that is engaged to your partner no one else. Your partner can also help you with this by reminding you of why they picked you. Not every day and not always by telling you. There are always little things that they can do that will help you become more self-confident in who you are. Now I am going to give you some strategies for active, critical, and empathetic listening. There are many strategies for active, critical, and empathetic listening. You can start out by keeping eye contact with a speaker, if you ask any questions make sure that you restate they key point to let the speaker know that you were listening and understood what they were trying to say. For the empathetic listening you also always make sure you keep eye contact and constantly make sure that the speaker knows that you feel where they are coming from. For example to let them know that you were listening you can repeat that one vary important thing that they may have said. Like â€Å" So you do not like it when I put my hair brush on the vanity other than in the cabinet.† If you do not have these strategies for listening in your relationship it is easily mistaken for you are not listening to that person. And it could cause many arguments over something that could have been prevented due to the fact of you facial expressions and body language. Always try and keep eye contact and restate the message so you all know that you are on the same page. It will be a lot less stressful on you both and your relationship. Some days it may seem like silly little things that you or your partner want to talk about, but those silly little things are what can start arguments if you are not really listening to what they are saying. These are the things that can cause most relationships to fall apart. Words can a have a huge affect on people, all depending on your tone of voice and your body language. For instance the word â€Å"AND†, depending on how you use that word it could affect the other person’s attitude or even perception to what you are trying to say. Here is an example of how a conversation could have a negative outcome. †Well, I have some good new  AND†¦Ã¢â‚¬  Many people look at the word â€Å"AND† and feel that it is a negative word that something bad is fixing to be said. The other word that can get one is also the word â€Å"SO†, we sometimes think as â€Å"SO† as a bad word or as one of the words that make us want to pull back into a safe pace or even become offensive when we hear the word â€Å"SO†. I would recommend that you should never start out a conversation with the word â€Å"AND† or use the word â€Å"BUT† following too far behind due to the fact of the way that people look at it which is negative and can cause a whole lot of stress on the other person in the conversation. You do not want to have that sort of stress and negative approach in your relationship with each other or anyone else. It will keep the impatients and frustration out of the air for a better relationship for the both of you. You also never want to start your conversation with â€Å"I love you BUT. This will have the other person thinking that really bad stuff is about to happen and no one wants that to be the case. Emotional intelligence is a set of skills that can be learned. Understanding emotions and how people express them is very important in interpersonal relationships because people who are aware of others emotions and are sensitive to emotions are able to deal with life’s ups and downs. They will also have a better self-concept, and look at others with care. You want to try to be aware of the way that your partner is feeling and try to put yourself in there shows, there will always be a time that you are going to wish that they would better understand what you are going through. These are also the times when you can talk to them and try to get a better understanding of what they are going through. Just remember to not be pushy and let their body language tell you when they are ready to really talk about what is going on in their life. Theses time will also give you an opportunity to strengthen your relationship and talk about things that make you each who you are. Your self-concept or self-image can make a huge impact on others. If you behave in a positive manner and give supportive messages than people will be able feel positive themselves and not have as bad of a self-concept. If you  were to give a negative behavior or say something that sounds negative it can cause your communication with that person seem to take the negative road. You want to take the time to help bust your partner’s self-image by leaving them little notes on the things that you like about them. One of the best paces that you can leave them a note is in their lunch bag, on a morrow, in the car, or even a memo in their phone to go off at some random time of the day. I hope that after each of you have read this letter, it soon helps you to both work on your communication skills with each other and can improve your relationship more than what it already is. I also hope that this will help you thorough the planning and all that come after the wedding. There is always time to talk to one another. Communications is one of the prime parts of having a good relationship and is what helps it stay healthy for years to come. Reference: Alarez, J. (1990). Self Concept.

Also, the difficult transitions between ol d and new technologies can be facilitated by the expertise of one of the partners. Enhancing strategic growth. Alliances provide a tremendous opportunity for organizational learning.In addition to learning from one another, partners are forced to learn more about themselves and to become more flexible so that these alliances work. Building financial strength. In addition to addressing these competitive Issues, alliances can help to build financial strength. Income can be Increased and administrative costs can be shared between partners or even reduced owing to the expertise of one or both partners. Of course, alliances also limit investment exposure by sharing risk (D. Smirch-Levi, Samisens ; E. Smirch-Levi, 2008, p. 248).If these mutual partnerships are to succeed there needs to be a mutual business understanding built up of respect, honesty, trust, communication and a desire for each party to profit by recognizing that the success of one partner helps with the success of the there (Rioter, 2007). Of course there needs to be compliance with all laws but also within the partnership between buyers and suppliers there needs to be respect, honesty, open communications and strategic financing that benefits all the parties involved (Rioter, 2007). Types of RSVP There are three types of Retailer-supplier Partnerships (RSVP) Strategies.They are the: Information sharing/quick response strategy – supplies receive point of sale (POS) data from retailers and use this Information to synchronize their production Ana Inventory actively wilt actual sales at ten retailer. In tons strategy ten retailer still prepares individual orders, but the POS data are used by the supplier to improve forecasting and scheduling and to reduce lead time. Continuous replenishment strategy (rapid replenishment) – vendors receive POS data and use these data to prepare shipments at previously agreed-upon intervals to maintain specific levels of inventory.Suppliers may gradually decr ease inventory levels at the retail store or distribution center as long as service levels are met. Inventory levels are continuously improved. Inventory levels could be based on sophisticated models that change appropriate levels based on seasonal demand, promotions, and changing consumer demand. Vendor-managed inventory (VIM) (vendor managed replenishment) (VIM) – the supplier decides on the appropriate inventory levels of each of the products (within previously agreed upon bounds) and the appropriate inventory policies to maintain these levels.In the initial stages, vendor suggestions must be approved by the retailer, but eventually the goal of many VIM programs is to eliminate retailer oversight on specific orders (D. Smirch-Levi et al. , 2008, p. 254). Requirements of RSVP As with any venture, there are requirements that must be met in order for the Retailer-supplier Partnerships (RSVP) Strategies to succeed. The most important requirement for an effective RSVP is to hav e advanced information systems on both sides of the supply chain.Electronic data interchange (DEED') or Internet-based private exchanges are essential to cut down on data transfer time and entry mistakes. Bar coding and scanning are essential to maintain data accuracy. And inventory, production control, and planning systems must be online, accurate, and integrated to take advantage of the additional information available. Such a partnership may shift power within the organization from one group to another which in turn might cause conflict within the organization itself. However, RSVP requires partners to develop a certain level of trust without which the alliance is going to fail.Confidential information is provided to the supplier. The top management at the supplier must understand that the immediate effect of decreased inventory at the retailer will be a one-time loss in sales revenue (D. Smirch-Levi et al. , 2008, p. 256). Issues with RSVP â€Å"One major issue is the decision concerning who makes the replenishment decisions nice inventory ownership issues are critical to the success of this kind of strategic alliance effort (D. Smirch-Levi et al. , 2008, p. 257). † Conflicts may arise about ownership issues.Ownership of goods are transferred to the retailer when originally received but more of a consignment relationship is needed with this type of alliance which leaves the supplier still owning the goods until the goods are sold (D. Smirch- Levi et al. , 2008, p. 257). Since the supplier owns the inventory, they might be a bit more concerned on how the buyer handles the management of said items. The errs and suppliers at this point might not agree on the way the inventory is handled at said location(s) and the buyer might feel that their toes are being stepped on in their own house.This might cause a bit of conflict and tension for both parties. In Vendor Managed Inventory (VIM), one tries to optimize the entire system by coordinating production an d distribution. The supplier can decrease their total costs by coordinating production and distribution for several retailers. However, the supply contract must be negotiated so that the supplier and the retailer share overall system savings (D. Smirch-Levi et al. 2008, p. 257). Performance measurement criteria must De agree o at . Polyglot sale (POS) accuracy, Inventory accuracy, shipment Ana delivery accuracy, lead times, and customer fill rates are commonly used.Confidentiality is an issue. A retailer who deals with several suppliers within the same product category may find that category information is important to the supplier in making accurate forecasts and stocking decisions. In many cases, the supplier in a partnership commits to fast response to emergencies and situational changes at the retailer (D. Smirch-Levi et al. , 2008, p. 257). The buyer of course is cooking to get a fair price but the supplier has to make sure he is covering all of his costs while still managing t o make a profit. It is not always in the buyer's interest to negotiate down to the very lowest price; the result can be less trust or loyalty from the vendor (Rioter, 2007). † Trust and constant communication are the key factors in any alliance being business or otherwise. A sustainable relationship cannot exist if those key elements are missing. In this way, clear concise contracts are needed for all parties so that there is no deviation from the norm and each party knows what its unction and objectives are within the partnership so that conflicts can be minimized and profits maximized.

Wood is an important worldwide renewable natural resource.

Chapter 1: Introduction1.0 IntroductionWood is an of import worldwide renewable natural resource. Forests comprise about one-third of the Earth ‘s entire land mass ( 3.4 million km? ) . There are an estimated 12,000 species of trees, each bring forthing a characteristic type of wood. ( International Agency for Research on Cancer, 1995 ) Wood based industry in Malaysia comprises four major bomber sectors. There are sawn timber veneer and panel merchandises, which include plyboard, and other reconstituted panel merchandises such as particleboard, hardboard, or fibreboards, moldings, builders joinery and woodworking, furniture and furniture constituents. The industry is preponderantly owned by Malayan and it is estimated that 80 per cent to 90 per cent of the companies comprise little and average sized constitutions. In Malaysia, furniture makers produce a broad scope of furniture from dining room, sleeping room, kitchen, office, occasional, living room, upholstered furniture or couch, outdoor and garden furniture. In Malaysia wood based industry for furniture and fixtures public presentation, furniture industry is extremely export-oriented with over 90 per cent of its production exported. Malaysia presently ranked as the ten percent largest exporter of furniture in the universe and 2nd in Asia after the People ‘s Republic of China, with exports to more than 160 states. In 2008, exports of wooden furniture amounted to RM 6.8 billion. The chief export finishs were the United States of America, Japan and Australia. The export value is expected to make RM 10 billion by 2010.More than 80 per cent of the furniture exported from kitchen furniture, sleeping room furniture, upholstered with wooden frame, and office furniture are made from gum elastic wood, or Hevea Brasiliensis which is a light colored, medium hardwood popularly called â€Å"Malaysian Oak.† As the demand for exports of furniture additions, so does the production rate additions, and in Malaysia furniture industry, the wellness jeopardy associated with wood dust have yet receive coverage particularly with concern to the wellness of its workers and to the environmental air quality environing it. Wood dust is defined as any wood atoms originating from the processing or handling of forests. Wood dust is generated when lumber is processed, such as when it is chipped, sawed, turned, drilled, or sanded. ( Occupational Safety Health Administration, 1989 ) . Wood dust is normally measured as air-borne atom dust concentration, by atom size distribution, by type of wood, and by other features of wood ( International Agency Research Cancer 1995 ) . Wood dust is used to fix wood coal, as an absorbent for glyceryl trinitrate, as a filler in plastics, and in linoleum and poster board ( Radian. , 1991 ) . Another commercial usage for wood dust is in wood composts ( Weber et al. , 1993 ) .Wood dust occurs in the environment in countries where machinery or tools are used to cut or determine wood. No flash-point informations are available for wood dust. However, wood dust is flammable and will light in the environment. It may show a strong to severe detonation jeopardy if a dust cloud contacts an ignition beginning. Wood dust is stable under normal laboratory conditions. Exposure to wood dust occurs to persons utilize machineries to cut or determine wood. Deposition within the air passages depend on the size, form, and the denseness of the dust atoms and the turbulency and speed of the air flow. ( International Agency Research Cancer 1981 ) . Use of manus held electric smoothers are identified as a peculiarly dusty, which would take to exposure to wood dust. Wood dust concentrations vary with type of dust extraction, sum of wood removed and type of smoother. ( Thorpe and Brown, 1994 ) . Different type of wood will besides bring forth different sum of dust. Hardwood and deal are different in the physical chemical belongingss that leads to the different in the sum of wood produced.1.1 Significance of surveyThe significances of this survey are:To detect the degree of safety and wellness consciousness among the workers of wood working to wood dust.To propose a extenuation attack to minimise the exposure to wood dust through technology control and good ho use maintaining.1.2 Aims of the surveyTo measure the exposure of wood dust concentrations on sanding and routing wood procedures in a Rubber wood furniture mill.To suggest appropriate steps to cut down wood dust emanation in the furniture mill.1.3 Problem statementWood dust is known to be a human carcinogens based on surveies done by Research workers from the Department of Health and Human Services in United States and American Conference of Governmental Industrial Hygienists ( ACGIH ) proposed 1 mg/m? of eight hr Time Weighted Average value for all wood dust species. In general, exposure to inordinate sum of wood dust is considered to hold an irritant consequence on eyes, nose, and pharynx in add-on to pneumonic map damage. Therefore, the intent of holding a monitoring plan is to measure and supervise the degree of exposure of wood dust to the environing environment and particularly on workers that have historical background or old record of holding any related wellness jeopardies to wood dust.1.4 HypothesissThe hypotheses in this survey are:Entire wood dust concentration and Respirable dust concentration on sanding and routing procedures in furniture industry falls into the standard bound as proposed in Occupational Safety and Health Act 1994 by Department of Occupational Safety and Health Malaysia ( DOSH Malaysia ) which is 1 mg/m3.Furniture mill have their ain safety steps taken to cut down the sum of dust emitted by the usage of cyclones and Personal Protective Equipment wore on workers.1.5 Case survey backgroundThe location for this survey is in Muar, Malaysia one of the most concentrated part for furniture fabrication industry and production of Rubberwood furniture ‘s. The mill is situated a t the 4th Lot in Industrial Zone Parit Jamil, where Rubber wood furniture merchandises such as table leg, bed stations, light base are made. The mill itself has 100 workers, chiefly are from Nepal, Bangladesh and Myanmar.1.6 Limitation of surveyQuestionnaire signifiers that have been distributed are chiefly done in Bahasa Malaysia due to linguistic communication restraint among workers from foreign states such as Bangladesh, Myanmar, Vietnam and Nepal workers in the mill.Chapter 2: LITERATURE REVIEW2.0 IntroductionForests cover about tierce of the universe the Earth ‘s entire land country, about 3.4 million km2.There are 3.5 thousand million M3 of the tree biomass is harvested, about half which is used as fuel, the remainder as sawn wood, pulpwood, and more. ( Gichner. , 1995 ) . There are an estimated 12, 000 species of trees, each bring forthing a characteristic types of wood.2.1 Definition of wood dustOccupational Safety and Health 1989 stated that wood dust is defined as a ny wood atoms originating from the processing or handling of forests. Wood dust is generated when lumber is processed such as when it is chipped, sawed, turned, drilled or sanded. Harmonizing to IARC 1995, Wood dust is known as a light brown or tan hempen pulverization. It has a specific gravitation of 0.56. Most tree species are deciduous tree, hardwood chiefly angiosperms. Merely about 800 species known as deal are Gymnosperms, or cone-bearing species, . ( Bauch. , 1975 )Type of woodThe footings â€Å"hardwood† and â€Å"softwood† does non needfully mention to the hardness of the wood, but to the species. Hardwood is by and large denser compared to softwood, where the denseness varies well within each group. The scientific and common names of some deal and hardwood are compiled in table 1 ( Vaucher. , 1986 ) . Wood dust is besides characterized by its wet content: Dry wood ( moisture content less than approximately 15-20 % ) is less elastic than moist ( green ) wood, and woodworking operations with dry wood consequence in a larger volume of entire dust and a higher per centum of inhalable dust atoms ( Hinds. , 1988 ) .2.2 Occupational exposure to wood dust.Dust exposure occurs in a big figure of woodworking industries, where dust arises from scratch, grinding, screening or blending. Traditionally, wood dust is considered as a nuisance dust, and its inauspicious effects on open workers have merely received attending. ( W.K.Liu et al. , 1985 ) . Harmonizing to Jones and Smith 1986, in this century, veneer- and plastic covered hardboard and fiber-board panels have been used intensively for the industry of cabinets, table tops and similar and hardwood merchandises. Solid hardwoods and hardwood-veneered panels are used for high-quality furniture because of the attractive form formed by their grains. Wood dust exposure occurs in chiefly as an occupational exposure in some industries and businesss. The partial list of open workers includes lumbermans ; sawmill workers, workers involved in the industry of plyboard and other boards, wooden furniture workers and cabinet shapers, workers in the industry of other wood merchandises, and carpenters and joiners in the building industry. Exposure to wood dust has long been associated with a assortment of inauspicious wellness effects, including dermatitis, allergic respiratory effects, mucosal and non allergic respiratory effects, and malignant neoplastic disease. Other symptoms associated with wood dust exposure include oculus annoyance, rhinal waterlessness and obstructor, prolonged colds, and frequent concerns. The type and degree of exposure to wood dust can be described in several ways. A first of import feature is the type of wood ( hardwood, deal ) and tropical wood, or other wood species. Hardwoods are deciduous trees such as oak, beech, calcium hydroxide, ash, birch, poplar, elm, or cherry trees. Softwood is cone-bearing trees, such as fir, spruce or pine. Wood is besides characterized by its wet content, which depends both on the species and on the freshness of the wood. The concentration of airborne dust is by and large measured in mg/m? with standard methods. ( IARC, 1995 ) The atom size is besides an of import parametric quantity, because the deposition form in human upper and lower air-ways partially depends on the atom size. Large atoms ( & gt ; 10 µm ) are about wholly deposited in the olfactory organ. Researchs on wood dust believe that comparatively that few atoms larger than 5 µm, which form most of the wood dust, yesteryear into the lungs every bit far as the clearance mechanism of the olfactory organ is non impaired. The inquiries on whether wood dust or dust from one or several forests contains carcinogens have been raised. There is no clear reply to this inquiry. A really big figure of chemical constituent are present in wood. Cellulose, polyoses, lignin, terpene, terpenoids, fats, waxes and phenolic compounds such as tannic acids, but none is a known carcinogen. ( Leclerc and Luce. , 1998 ) Types of business are straight related to the sum of exposure to wood dust. Lumbermans and sawmill workers are exposed to comparatively big atoms of fresh wood. The average degree of wood dust is by and large lower than 1mg/m3. Wooden furniture industry and cabinet devising involves a big figure of woodworking procedures, such as sawing, planning, come offing, sanding and usage of milling machines that produce wood dust ( Nylander et al. , 1993 ) A assortment of species are used, with predomination of hardwood for high quality furniture manufactured by cabinet shapers, for illustration in Asiatic states. The average size of the atoms may be particularly little, because the forests need to be really dry, which produces really finer atoms and the sanding, is much finer for furniture industries, for aesthetic grounds. There is some grounds that sanding of hardwood can bring forth finer smaller atoms. ( Acheson. , 1976 )2.3 Sanding of wood.Sandpapering is smoothing the surface of wood â €Å"an scratchy procedure in which borders of little, difficult, crystalline atoms are quickly drawn across the surface of the wood, with force per unit area being applied perpendicular to the surface† ( Holliday et al. , 1986 ) . The smaller the scratchy atoms, the finer the dust produced, and the faster the smoother, the greater the sum of dust produced. Sandpapering is the normally used come uping method continuing wood coating ( Williams and Morris. , 1998 ) . The chief aim of sanding is to do surfaces free of seeable defects every bit good as to makes surfaces uniformly absorbent for coatings ( Richter et al. , 1995 ) Sandpapering is done in many wood industries, with little, handheld smoothers to big membranophones or belts for smoothing a full panel. There are few different ways in sanding of wood. The most common are the belt smoother, where a uninterrupted strip of emery paper rotated between two rollers, the disc smoother, where a round piece of emery paper fastened to a revolving disc, the membranophone smoother, where a uninterrupted strap of emery paper rotated on a membranophone, and the orbital smoother, which operates with an egg-shaped, vibrating gesture. Use of manus held electric smoothers has been identified as a peculiarly dust-covered procedure, which would take to exposure to dust. Wood dust concentrations vary with type of dust extraction, sum of wood removed, and type of smoother ( Thorpe and Brown et al. , 1995 ) . For electrical orbital smoothers without built-in dust extraction, entire inhalable or inspirable dust concentrations ranged from 0.42 to 8.01 mg/m3, dust concentrations were reduced 84.3 % to 97.97 % when the smoothers were used with fitted bags. For electric belt smoothers, entire inhalable dust concentrations ranged from 10.2 to 19.8 mg/m3 without built-in dust extraction and were reduced 66.1 % to 93.5 % with bags. For electric orbital smoothers with external dust extraction, entire dust concentrations ranged from 0.022 to 0.739 mg/m3, and respirable dust concentrations ranged from 0.003 to 0.936 mg/m3. Rotary smoothers with external dust extraction produced entire dust concentrations ranged from 0.002 to 0.699 mg/m3, and respirable dust ranged from 0.001 to 0.088 mg/m3. A survey carried out on the dust coevals features of hardwoods during sanding procedure reveals that sum of wood removed during the sanding procedure predetermined dust-generation, although the wood denseness and scratchy grit used played a function. Consequently, low denseness wood species produced higher dust-concentration due o its comparative easiness of sanding, and vice-versa. Different sanding operations will bring forth different sum of dust concentration ( Graham and Ratnasingam.,2007 ) . This is proven by a survey carried on six hardwood species stand foring commercially of import hardwoods use in Malayan wood merchandises fabricating industry selected based on hardness and denseness as in Table 2.1.Hardwood speciesAverage denseness ( kg/m3 )Average hardness ( N )Resak ( Vatica sp. )8707040Balau ( Shorea sp. )8206980Kelat ( Syzygium sp. )6705140Merawan ( Hopea sp. )6405080Rubberwood ( Hevea sp. )5403440Meranti ( Shorea sp. )5303610Table 2.1: Malayan Hardwood species used in wood merchandises fabricating industry. ( Taken from Dust-generation features of hardwoods during sanding procedures ) Ratnasingam et al. , 2009. From the survey conducted, it is shown that the sum of wood removed is the most of import factor finding dust-generation during wood sanding processes. Machine sanding utilizing belt-sanding procedure yielded the highest dust concentrations compared to manus sanding. This is shown by the important alteration in dust concentration shown in Table 2.2 below. .ProcedureDust concentrations ( mg/m3 )Average wood remotion ( gms )Hand sanding197Orbital sanding269Wide belt-sanding4318Edge sanding166.5Stroke sanding3111Brush sanding115.5Table 2.2: Dust concentration at different sanding procedures: Taken from dust-generation features of hardwoods during sanding procedures. by Ratnasingam et al. , 2009. Based on the consequences, about all sanding operations produced dust concentration higher than the standard allowable dust exposure degree of 5mg/m3, proposing that sanding dust control is of import in the furniture fabrication industry, if wellness and safety criterions are traveling to be met ( Graham and Ratnasingam et al. , 2007 ) .2.4 Properties and Toxicity of wood dustWood dust is one of the most common organic dusts workers are exposed to in the furniture fabrication industry. ( Ratnasingam et al. , 2009 ) . Surveies have found that exposure to wood dust can do wellness effects like rhinal mucosa harm, annoyance and Sino-nasal malignant neoplastic disease, while deep lung deposition can take to lung malignant neoplastic disease and impaired respiratory map ( Shamssain. , 1992 ) and ( Mikkelsen. , 2002 ) . Therefore a survey was undertaken to measure air-borne wood dust concentration and its atom size distribution in the Malayan Rubberwood furniture industry, one of the large st wood industry in South East Asia. Sampling periods of 8 hours were undertaken at the routing and hand-sanding work Stationss to find the Time-weighted mean value of wood dust concentration. The mean air-borne dust concentration recorded for routing work station ( 63mg/m3 ) was lower than the sanding work station ( 89 mg/m3 ) . This value was higher than the standard eight hr Time Weighted Average Maximum Exposure Limit for wood dust of 5mg/m3 ( FMR1989, HSE1999 ) , and hence the high air-borne wood dust concentration in the mills poses respiratory-related wellness hazards.In footings of atom size distribution, this survey revealed that less than 25 % of the air-borne dust by weight at the two work Stationss were less than 10 µm. Hence, the emanation during consequences indicate that merely a little part of the air-borne wood dust atom is capable of perforating into the lower parts of respiratory system to do serious wellness jobs. However, this survey besides show that it is due to air-borne wood dust concentration, and non the wood dust atom size distribution that posses serious menaces to the respiratory system of workers in the Rubberwood furniture fabricating mill s. Another survey did carried out was to measure air borne dust emanation ( 0.1-10 µm ) during the routing operation of Rubberwood ( Hevea Brasiliensis ) in the furniture industry in South East Asia. ( Ratnasingam et al. , 2009 ) . The emanation of airborne wood dust during the machining of Rubberwood ( Hevea Brasiliensis ) consequences in increased incidence of respiratory jobs and rhinal malignant neoplastic disease among workers in the South East Asiatic furniture industry ( Anon. , 2008 ) .Rubberwood ( Hevea Brasiliensis ) being the most of import natural stuff for the wooden furniture industry in the South East Asia part, therefore the survey on the consequence of dust emanation during its machining are of import as to set up a benchmark for industrial wellness guideline for the Rubberwood processing industry in this part. The consequences showed airborne dust in the scope of 0.1-10 µm had the most terrible consequence on the wellness of workers. 68 % of the workers confirmed as agony from some respiratory-related jobs after five old ages of drawn-out exposure. The experiments showed that the mean bit thickness has the greatest influence on dust coevals during the routing operation followed by wood wet content and rake angle. It is shown that airborne dust emanation during the routing procedure of Rubberwood could be minimized by aiming an mean bit thickness of 0.1mm, while maintaining the wet content in 12-14 % scope. These should remain as guidelines to minimise the airborne dust emanation, which in bend will cut down the wellness jeopardy posed by airborne dust to workers in Rubberwood furniture mills in South East Asia ( Ratnasingam et al. , 2009 ) .2.5 Human malignant neoplastic disease surveies of wood dustRecent surveies of wood dustIn December 2000, a study by U.S Department of Health and Hum an Services National Toxicity Program entitled â€Å"Report on Carcinogen for Wood Dust† stated in its drumhead statement that Wood dust is known to be a human carcinogen, based on sufficient grounds of carcinogenicity from surveies in worlds. It has been demonstrated through human epidemiologic surveies that exposure to wood dust increases the happening of malignant neoplastic disease of the olfactory organ ( rhinal pits and paranasal fistulas ) . Strong and consistent associations with malignant neoplastic disease of the rhinal pits and paranasal pits were observed both for businesss associated with wood dust exposure and for straight estimated wood dust exposure. Hazards were highest for glandular cancer, and other types of nasal malignant neoplastic diseases ( squamous cell carcinoma of the rhinal pit ) and malignant neoplastic diseases at other sites, including the nasopharynx, the voice box, and Hodgin ‘s disease have been associated with wood dust exposure in several epidemiologic surveies. The function of specific chemical constituents of the wood ( of course happening or exogenously added compounds ) in wood dust-induced carcinogenesis is ill-defined. The particulate nature of wood dust may besides lend to wood dust-associated carcinogenesis since dust generated by wood working typically consists of a high proportion of atoms that are deposited in the nasal cavity.Chronic exposure to wood dust particulates is associated with reduced mucociliary clearance and enhanced inflammatory reactions in the rhinal pit in some surveies in worlds. Additionally, cellular alterations ( metaplasia and dysplasia ) observed in the rhinal mucous membrane of wood workers and laboratory animate beings may stand for preneoplastic provinces. A survey on 4247 adult females employed in a Norse mush and paper factory for at least one twelvemonth between 1920 and 1993, supervising their malignant neoplastic disease incidence from 1953 to 1993, supervising their malignant neoplastic disease incidence from 1952 to 1993. Compared with the national female population, adult females employed for at least three old ages in mush and paper work showed an ovarian malignant neoplastic disease standardized incidence ratio ( SIR ) of 1.6 ( 95 % CI = 1.1 to 2.3, 3.1 instances ) . Elevated SIRs were seen for lung malignant neoplastic disease and multiple myeloma in adult females with less than three old ages exposure, but non for longer exposures. No rhinal malignant neoplastic disease instances occured in the population. Wood dust exposure was non estimated straight, doing dose response hard to measure, and the survey ‘s size limited its power for most results ( Langseth and Anderson et al. , 1999 ) ( Imos et al. , 2000 ) studied 3723 male and 3063 female workers employed at two furniture mills in Estonia from 1946 onward, followed through 1995 for incidence of malignant neoplastic disease. Workers were classified as holding low, medium, , or high strength of exposure based on employment records. Nasal consonant malignant neoplastic diseases were twice every bit common as expected, compared with the national population, but this was based on merely three instances ( all of which occured among extremely open workers. ) The lone significantly elevated hazard rose with strength of exposure among adult females, but non among work forces ; incorporation of a 20-year latency premise stengthened the association. The usage of totl incidence alternatively of mortality, every bit good as consideration of strength of exposure and slowdown effects, were strenghts of this survey. However, the sample size limited the ability to observe elevated hazards of rarer malignant neoplastic diseases. In a survey conducted on genotoxicity of wood dust in a human embryologic lung cell line, utilizing cell civilization technique, a survey on comparative genotoxic activities of two difficult forests ( beech and oak ) and a soft wood ( pine ) a cell civilization with human lung cells. It is learn that among the untreated forests processed in furniture industries, difficult forests, peculiarly beech and oak have been often suspected to incorporate carcinogenic belongingss in their natural components. It has been shown that beech wood infusions induce weak mutants in bacteriums ( McGregor 1982 ; Mothashamipur et al. , 1986 ) , an enhanced figure of atomic abbreations in duodenal crypts of mice ( Mothashamipur and Norpoth. , 1989 ) , micronuclei in rhinal epithelial tissue of rats ( Nelson et al. , 1993 ) , and malignant tumours on mouse tegument ( Mothashamipur et al. , 1989 ) . Although occupational exposure to wood dust is encountered during all phases of wood processing, the comparatively higher hazard of developing malignant neoplastic disease is associated with the increased degree of wood dust in the ambiance ( Mothashamipur et al. , 1989b ) . However, the strongest associations of exposure to wood dust and malignant neoplastic disease development is observed in businesss where merely difficult forests but no additives are used ( Nylander and Dement. , 1993 ) . The consequences of the survey show that extracts of untreated difficult forests cost important chromosomal and chromatid interruptions in embryologic lung cells, but such a phenomenon was non observed with the deal. A farther comparative survey on DNA-strand interrupting effects of hardwoods ( beech, oak ) and a deal ( spruce ) has been done in vitro utilizing rat hepatocytes ( Schmezer et al. , 1994 ) .2.6 Surveies of malignant neoplastic disease in Experimental animate beingsCarcinogenicity o f wood dust and wood additives in rates exposed by long term inspiration.In 1965, Macbeth reported on 20 patients with rhinal glandular cancers in the country of High Wycombe in England, of whom 15 had worked in the furniture industries. Between 1967 and 1972, more elaborate information was provided and in 1969, the tumours were recognized as occupational disease. Numerous epidemiological and toxicological surveies of the carcinogenic consequence of wood dusts were published, which fundamentally confirmed the consequences obtained in England. In 1985, oak and beech wood dusts were classified as carcinogenic to worlds by Senate committee of the German Society for the promotion of Scientific Research ( Deutsche Forschungsgemeinschaft ) in Germany, and other wood dusts as suspected carcinogens. In 1999, hardwood dusts were classified as carcinogenic agents by the Commission of the European Union, on the footing of the IARC categorization of the carcinogenic potency of wood dusts in 199 5. A research undertaking was initiated to measure exposures happening in the wood industry consistently, and to understand better the manner of formation of glandular cancer of the olfactory organ. Epidemiologic surveies were excluded, as the figure of noxious agents was excessively great, and neither employers nor workers know precisely what type of agents were used, although the type and additives such as varnish, discolorations, gums and wood preservatives that are used are known, frequently the pretreatment of the wood is unknown Long-run experiments in which animate beings were exposed to inspiration seemed to be a suited method, provided that the malignant neoplastic diseases observed in worlds could be induced in research lab animate beings under comparable conditions. As the Numberss of agents was excessively big for systematic proving in such experiments, short-run surveies of toxicity and genotoxicity were carried out to function as a footing for the design of long term exper iments. Material used in the survey include Oakwood dust, because it is the most genotoxic of the wood tested ; the genotoxicity was tested with cyclohexane infusions. Wood preservatives incorporating lindane and pentachlorophenol ( PCP ) , because lindane was genotoxic in human nasal cells. Chromate is besides used, which is genotoxic, includes drawn-out rhinal clearance and, when used in wood preservatives, may take to dysplasia. Chromate has often been used in the wood-processing industry, peculiarly as K bichromate in discolorations but besides as a repair agent in wood preservatives A group exposed to N-nitrosodimethylamine ( NDMA ) served as positive controls, because rats exposed to certain nitrosamines are known to develop tumours of the rhinal pit. Exposure and animate being handling were performed harmonizing to the German Law on the Protection of Animals. The exposure tracts of rats to wood dusts and wood preservatives are such that all the coops of all seven experimental groups were rotated daily within their exposure boxes, harmonizing to a strategy documented for each group and twenty-four hours. When all exposed animate beings are considered together, the consequences go even more pronounced. Fatal respiratory piece of land tumours occurred in the five of 155 animate beings exposed to oak wood ( P = 0.08, Fischer trial, when compared with the negative control ) , in five of 102 animate beings exposed to chromate ( P = 0.03 ) and in two of 101 animate beings exposed to lindane and PCP ( P = 0.17 ) while such tumours were non seen in the 96 negative cont rols. These measurings in the terminal do non allow a decision about the extent to which chromate histories for the effects associated with exposure to oak and beech wood dust or for the epidemiologically ascertained regional fluctuations in tumorigenesis. More wood types from different parts will hold to be analyzed for chromate and compared.2.7 Minimizing dust emanation by the usage of tool geometry.Dust created in the machining of wood is a major job in the on the job environment. Minute wood atoms carried through the air make a serious wellness jeopardy, in utmost instances even taking to malignant neoplastic disease. In wood working industries, it has proved a jeopardy to workers wellness, particularly in the signifier of malignant neoplastic disease of the nasal and paranasal fistulas. A sum-up of probes of wood dust and the hazard of malignant neoplastic disease can be found in Nylander and Dement ( 1993 ) , where the writers states that secret agents in the wood working industry face a higher hazard of developing rhinal malignant neoplastic disease, particularly those working with machines that generate wood dust. An experimental survey did by J. Palmqvist et al. , 1999 on the influence of cutting informations and tool geometry in cut downing dust emanations at the beginning, that is at the tip of the tool. Method used on three different wood stuffs such as, pine, beech and fiberboard ( MDF ) . Specimens were processed in a miling machines where it was possible to change the film editing informations. The dust emanations from the tool ( defined here as atoms with a diameter less than 10 µm ) were measured. The parametric quantities altered in the experiments were moisture content of the wood, mean bit thickness, way of provender ( up or down ) and rake angle of the tool. The experiments showed that the mean bit thickness had the greatest influence on the sum of dust created when machining wood and wet content of the wood, a reasonably great influence, and while the way of the provender and and the profligate angle had small or no influence. The consequences show that dust emanations increase quickly when making a certain mean bit thickness. It is hence of import to cipher and command the mean bit thickness in order to minimise the dust emanation between the three wood tested.2.8 Routers and Sanders safety jeopardiesRouters are used for such intents such as cutting and determining cosmetic pieces, doing frame and panel doors, and miling moldings.. The tool-spindle axis is normally perpendicular, but it may be tilted. The operator lowers the caput for machining, and the caput automatically returns to its original place after the cut is made. Operators may be injured from accidental contact with the routing tool when managing stock or taking bit from the tabular array. Kickback is another common beginning of hurt among routers operators. Projections of tools can badly wound or kill router operators. Tools can be flung from the cutter caput if they are ill fastened in the tool holder, if the incorrect tool is used, or if th e tool velocity is excessively high ( A usher for protecting workers from woodworking jeopardies, 1999 ) Router with Adjustable Tool Guard should be used to protect the routers from serious hurt that is caused by crisp instrument in knife vesica. Other that it, equip routers with a spindle braking system that bit by bit engages. In the average clip, some tips on safe work patterns such as properly attach and secure toolsto the holder, and label cutting tool and holders with the maximal allowable spindle velocity. Drum sanders are people who finish stock by utilizing a coated scratchy surface to take stuff. A belt smoother uses a systems of blocks to travel scratchy stuff accross the stock. Either the wood is fed manually or automatically into the machine or the sanding belt is pressed toward the wood, which is located on a working tabular array ( A usher for protecting workers from woodworking jeopardies, 1999 ) . Drum sanders produce quite a considerable measure of all right wood dust. All smoothers should be carefully ventilated. The primary safety jeopardies of belt smoothers us that workers may catch their custodies, vesture or jewellery in the running axial rotations. Safety work patterns should be to replace lacerate, frayed, or exessively worn belts or membranophones. A raddled belt, disc or membranophone can do a monolithic heat buildup, which can do the belt, disc or membranophone to rupture or interrupt and bombard the environing country with its projected spots. It is besides of import to maintain custodies off from scratchy surfaces and sand on the downward-moving side of the disc or belt. . ( A usher for protecting workers from woodworking jeopardies, 1999 ) .Chapter 3: Methodology3.0 Entire dust aggregation utilizing MiniVol Portable Air Sampler.The MiniVol Air Sampler is an ambient air sampling station for particulate affair and non-reactive gas. The patented low flow engineerin g used in MiniVol was developed jointly by the U.S Environmental Protection Agency ( EPA ) and the Lane Regional Air Pollution Authority in an attempt to turn to the demand for portable air pollution trying engineering. MiniVol gives consequences near about as in mention air quality informations. Both precise and accurate, the battery operated, lightweight MiniVol is ideal for trying at distant countries or station web. The MiniVol can be configured to try for a similar mention station web. In the particulate affair ( PM ) trying manner, air is drawn through a atom size centrifuge and so through a filter medium. Particle size separation is achieved by impaction. Actual volumetric flow must be 5 litres per minute ( 5 L/m ) at ambient conditions. Impactors are available with a 10-micron cut -point ( PM10 ) and a 2.5-micron cut-point ( PM2.5 ) . Operating the sampling station without an impactor allows for aggregation of entire suspended affair ( TSP ) . 2 unit of Minivol is used in this undertaking. Both theoretical account is taken to site and operated at 5 litres per minute. First theoretical account of Minivol is situated sanding country where there were two sanding maestro machine and random orbital sanding procedure is taking topographic point. Second theoretical account of Minivol is situated at country of where routing of wood is taking topographic point. This research was carried out in three hebdomads in the month of November and December 2009. Total suspended atom ( TSP ) was collected in this two station. The location to put the Minivol unit was chosen based on the work processes which produce more dust. First station, in routing procedures, dust produced by the routing machines are coarser and more dust are collected by the pump. In the 2nd station, wood sanding procedure by machines and manus is the work processes that were assessed. Sandpapering utilizing machines are done to smoothen the portion of furniture which is non even or to do the furniture finer in quality which make it a better market value.EquipmentSampler:47-mm PVC, 2-5 µm pore size membrane or tantamount membrane filter and back uping tablet in 47mm cassette filter holder.Minivol Air sampling stationMicrobalance, capable of weighing to 0.001mg.Forceps ( sooner nylon )Preparation of filters.Equilibrate the filters in an environmentally controlled weighing country or chamber for at least 2 hours.Number the backup pads with a ballpen pen and topographic point them, numbered side down, in filter cassette bottom subdivisions.Weight the filters in an environmentally controlled country or chamber.

The trying pump is worn on the neckband of the workers shirt, and is fastened by a limiter. Sampling pump that was used in this research is from the theoretical account Apex HB 3294-04. It uses an efficient stop pump whose flow rate is exactly maintained utilizing an automatic flow control circuit. The pump draws contaminated air through a sampling caput at a rate determined by the caput design or trying scheme. The Apex was developed to supply trying capablenesss between 5 ml/min and 5 l/min, suited for a broad scope of applications including solvent exhausts, asbestos clearance and personal sampling of dusts. Apex pumps are ideally suited to many of the Total and Respirable dust trying techniques detailed in U.K Health and Safety Executive publication MDHS14, and in other mention methods. The trying pump is operated at 2.2 L/min for Higgins-Dewell cyclone, for 8 hr daily for three hebdomads, from 8am to 5pm, working clip in the mill. The workers are chosen based on the wood processes that they do. The mill does non give its workers revolving occupation mundane, therefore it is easier to try on one individual for the whole twenty-four hours making the same work for an norm of 8 hours. Respirable dust is more of the sum of dust that enters the gas exchange part of the lung, therefore it is a really of import index of how the lung system can be affected by utilizing this instrument.EquipmentSampling station:Filter: 5.0  µm pore size, polyvinyl chloride filter or tantamount hydrophobic membrane filter supported by a cassette filter holderCyclone: 10-mm nylon, Higgins-Dewell ( BGI Inc. , 58 Guinan St. Waltham, MA 02153 ) ( 7 ) or tantamount.Personal Sampling pump, 2.2 L/min + 5 % for HD cyclone with flexible linking tube.Balance, analytical with sensitiveness of 0.001mg.Forceps ( sooner nylon )Environmental chamber or room for balance.Preparation of filters.Equilibrate the filters in an environmentally controlled weighing country or chamber for at least 2 hours.Number the backup pads with a ballpen pen and topographic point them, numbered side down, in filter cassette bottom subdivisions.Weight the filters in an environmentally controlled country or chamber.

The consequences informations collected for Entire dust and respirable dust in station 1 and station 2 concentration is besides analyzed utilizing Mann-Kendall Trend analysis. Mann-Kendall tendency analysis is a non-parametric trial for indentifying tendency in clip series informations. The trial compares the comparative magnitudes of sample informations instead than the informations values themselves. ( Gilbert. , 1987 ) . One benefit of this trial is that the informations need non conform to any peculiar distribution. Furthermore, informations reported as non-detects can be included by delegating them a common value that is smaller than the smallest mensural value in the information set. The procedurethat will be described i n the subsequent paragraphs assumes that there exists merely one informations valueper clip period. When multiple informations points exist for a individual clip period, the average value is used.3.3 Questionnaire on Occupational exposure to wood dust.The degree of exposure to wood dust is observed through a list of questionnaire to the estimated 30 % of entire workers in the mill. The study was distributed to 30 workers who work for full displacement of 8 working hours for the same everyday work procedures in the mill. Due to linguistic communication barrier among the workers from foreign states such as Bangladesh, Nepal, Vietnam and Indonesia, the questionnaire can merely be used through Bahasa Malaysia as the chief medium. The questionnaire distributed consisted of 3 parts, where first portion covers the personal information ( butir-butir peribadi ) of the workers such as the gender, age, weight, tallness, race and on the job clip. It besides covers on the past business of workers, how long have they work in the current mill and in the yesteryear as good. Separate 2 screens on the past work topographic point status, the environmental scene in which they work, and besides the erosion of Personal Protective Equipment such as mask, safety boots, suited working dress, safety goggles. Part 3 screens their on the job status in their current work topographic point. Same inquiry as proposed to portion 2, but an add-on smoke wont during work clip, and besides current industrial pattern on the cleanliness of dust emanation. A sum of 30 questionnaire were distributed to the workers involved in the mill chosen by choosing workers that are straight involved in this survey, that is routing and sanding procedures. Consequences from respondent are utilizing an analytical tool called Statistical Package for Social Sciences ( SPSS ) version 17.0.3.4 Location of surveyThis survey is carried out in Muar which is The town of Muar is located at 2 °3?N102 °34?E, at the oral cavity of the Muar River. The town is about 150 kilometers ( 93 stat mis ) sou'-east of Malaysia ‘s capitalKuala Lumpur, and about the same distance ( 179 kilometer ) northwest ofSingapore. It is 45km south ofMalacca Town. It is besides 50 kilometers north ofBatu Pahat. Beginning: www.maps.google.com.my Figure 3.1: Location of Muar, Johor. The mill is located at Parit Jamil industrial zone, Muar. There are 100 workers in production line based in the mill, where 60 % are foreign workers coming from Vietnam, Nepal, Bangladesh, Indonesia, Myanmar and local Malaysian. The mill operates from Monday to Saturday except for public vacations and Sunday. There are 5 section including Management squad where all the wood is process by modeling, determining, routing to finally do out a all right quality furniture. Below are some of the figures of wood procedures that are done in the mill.Chapter 4: Consequence AND DISCUSSION4.0 Independent samples T-test on Total dust for sanding and routing.The sum suspended atoms informations collected for routing and sanding procedures in the two Stationss was analyzed utilizing SPSS for independent samples T-test on Total dust for the two independent variables, sanding and routing. The chief intent of running the information utilizing T-test is tests the significance of the difference between t he two sample agencies. Hypothesiss: Nothing: the mean of two group are non significantly different Surrogate: the agencies of the two group are significantly different T-Test Based on Table 4.1, the average value of 1.6645mg/m3 for sanding procedures is higher than 1.5051mg/m3 from routing procedures. This means that on norm, sanding procedure output higher entire dust concentration than routing procedure in 17 workers from both Stationss. Therefore based on the average consequences, the void hypotheses is accepted.

Premises: 1: Sanding and routing procedures have about equal discrepancy on the dependent variables. 2: Sanding and routing procedures are independent on one another. Based on Table 4.2: The consequences for Levene ‘s trial for equality of discrepancy is that we accept our first premise that is sanding and routing procedures have about equal discrepancy because the value of significance is 0.557 which is greater than 0.05. Therefore the two discrepancy value is non significantly different. Table 4.2: Levene ‘s Test for equality of discrepancies for Total Suspended Particles.Levene ‘s Test for Equality of DiscrepanciesFSig.Sum Suspended AtomsEqual discrepancies assumed.353.557Equal discrepancies non assumedFrom the Table 4.3, Independent samples of t-test shown in equal discrepancies assumed from Levene ‘s trial, it can be conclude from the t value of -0.555 with grade of freedom 32, at important degree of 0.05, there is no important difference between the sanding and routing procedures. The sum of Entire dust produced in the sanding procedure is non significantly different from entire dust from routing procedure. Entire dust is collected from the dust that has accumulated in the ambient air, so it can non be measured specifically from which beginning the dust is coming from. Wind way, comparative humidness and different work undertaking done in same station may impact the motion of this all right dust atoms traveling approximately in the air.

This mean on norm, repirable dust on workers is higher in the sanding processes than routing procedures. Table 4.4: Group statistics for respirable dust on sanding and routing procedure.PersonNitrogenMeanStandard DeviationStandard Error MeanRespirableSandpapering174.48651.83743.44564Routing172.7509.81998.19887Based on table 4.5, for respirable dust, the two groups that is sanding and routing has about equal discrepancy for the two dependent variables. And the consequence shows that the important value is greater than 0.05 which is 0.260 which means that they are non significantly different. Table 4.5: Levene ‘s Test for equality of discrepancies for Respirable dustLevene ‘s Test for Equality of DiscrepanciesFSig.RespirableEqual discrepancies assumed1.316.260Equal discrepancies non assumedIn table 4.6, through Levene ‘s trial that the discrepancies are about equal, t value of 3.557 with 32 grade of freedom, at 0.05 important degree, it shows that there is important different in the sum of repirable dust from routing and sanding procedure. Respirable dust is the sum of dust measured in the take a breathing zone of the workers, which means it can mensurate the sum of dust that is inhaled into the lung by take a breathing the air indoors. This is an of import indicant to demo how much different wood working procedure produces different consequence on workers.

The entire dust collected for 3 hebdomads is tested to see the correlativity between the clip puting and variables for sanding and routing procedure. Based on table 4.7, the Mann-Kendall tau correlativity coefficient is 0.603. This positive value show an increasing tendency to Total dust value for sanding station. Table 4.7: Mann Kendall analysis for correlativity trial entire dust station1.Kendall ‘s tau Correlation TestUS Geological Survey, 2005Datas set: Example Totaldust values – Mann-Kendall trial, input type 4The tau correlativity coefficient is 0.603S = 82.omega = 3.337P = 0.0008The relation may be described by the equation:Y = 0.43264 + 0.1206 * TenTo back up this consequence, based on figure 4.1, it can be seen that there is a important addition for the 2nd hebdomad ( 14th Dec to 19th Dec 09 ) during this clip period, the concentration of entire dust rise from 1.995 mg/m3 to 2.175mg/m3 ) . For the undermentioned hebdomad, 21st Dec 09 to 26th Dec 09, there is a crisp addition in twenty-four hours 4 of reading, on the 23rd Dec 09, the value recorded was 3.804 mg/m3. This unusual reading may come as a consequence of the air current velocity, weave way and sum of wood being sanded throughout the twenty-four hours. There is a lessening of 2.286 mg/m3 for the last two twenty-four hours of monitoring. The sums of wood dust concentration have decrease due to alter in air current velocity and comparative humidness in the ambiance. High value of comparative humidness can do the air going more concentrated with the dust atoms and when the air current blows, it carries the dust around the ambient air inside the mill. Another factor that contributes to the high emanation of dust in the sanding procedure at station 1 in the 3rd hebdomad of monitoring is due to the usage of machines particularly the usage of two sanding maestro machine which is operated at different velocity and due to the different sum of dust generated by different wood usage, its difficult to command the emanation of dust manually by utilizing vacuity or brushing the floor. This may therefore even do the work topographic point dustier and difficult to maintain it clean. Based on table 4.8: the Mann-Kendall tau correlativity coefficient is 0.691. This positive value shows an increasing tendency for entire dust in station 2. Meanwhile, at 0.05 assurance interval, chance of 0.0001 which means there is important difference in the value of wood dust in station 2 reading every bit good. Table 4.8: Mann Kendall analysis for correlativity trial on Entire dust station 2Kendall ‘s tau Correlation TestUS Geological Survey, 2005Datas set: Example Totaldust values – Mann-Kendall trial, input type 4The tau correlativity coefficient is 0.691S = 94.omega = 3.831P = 0.0001The relation may be described by the equation:Y = 0.74132 + 0.1287 *TenThe graph shown in Figure 4.2 is monitored in station 2. The graph shows a positive increase in hebdomad 1, hebdomad 2 and hebdomad 3 of monitoring. In hebdomad 1, the value of entire dust does non increase significantly but on hebdomad 2, there were steadily increase over the whole hebdomad and this form continue until hebdomad 3 where the highest reading is on the 22nd Dec 09, 2.270 mg/m3. The lowest value was recorded in 18th Nov 09 where the reading is 0.561 mg/m3.The consequence shown in the graph comparing to Figure 1 is non as important in station 1. This is because at station 2, the entire dust concentration in the ambient air is affected by the usage of operating expense piping system where it is used to hoover out all the dust generated by machines and in each compartment, there are besides less dust accumulated throughout the work topographic point.4.3 Mann-Kendall tendency analysis on respirable dust.Table 4.9 shows the consequence end product for respirable dust on electrical orbital sanding procedure. The tau correlativity coefficient is 0.463 and this suggests that there is a positive increasing tendency shown in orbital sanding.
