Pat Buchanan :: History
Pat Buchanan Pat Buchanan is currently campaigning to become the Republican representative in the next U.S. Presidential election. He is credited with striking a chord amongst the main stream, blue collar sector of the country. This is because he has based his economic platform on common myths about free trade and how it is the cause of the economic problems in the U.S. His theme is that layoffs and the closing of American plants are the result of foreign companies and countries taking advantage of easy access into U.S. markets which, in his opinion, is not being reciprocated abroad. This is how he accounts for the current trade deficit that the U.S. is running with countries like Japan. Pat's economic platform regarding trade policy can be summarized as follows: * Impose a 10% tariff on Japanese imports and a 20% tariff on Chinese imports. This would generate, in his opinion, $20 billion in government revenue and reduce the trade deficit which could be reinvested into the American economy and help create tax cuts for small businesses. * Impose a social tariff on Third World manufactured goods to protect U.S. workers' wage rates from the foreign laborers who are paid a fraction of what their U.S. counterparts earn. He also resents that foreign companies do not have to adhere to the strict environmental, safety, and health standards that American firms do yet get free access to the U.S. market via GATT and NAFTA. It is evident that Pat Buchanan believes that trade deficits and trade with Third World countries are at the heart of what he perceives to be America's economic problems. He feels that through tariffs the burden of income taxes paid by U.S. workers and small businesses can be shifted onto consumers who purchase foreign goods. His underlying sentiment about his trade restrictive policies is, "This is our land; America is our country; the U.S. our market. We decide who enters here and who does not." The basis of international trade is that their are gains to be had from partaking in it. This was proven by David Ricardo, an economist in the early 19th century, who introduced the concept of comparative advantage. His theory stated that a country's "absolute advantage (overall productivity differences between countries) should be reflected in differences in income, whereas comparative advantage (variations in productivity differences by sector) will determine the pattern of international trade.

Cheap Stunts :: essays papers
Cheap Stunts Topic: Using basic techniques combined with creative thinking to achieve stunts and special FX, in low-budget film making. This paper has been written with the low budget film maker in mind. Seeing as though I am personally used to working with little or no money to produce a film or a video, I have always searched, through nessicity, for new ways to create effective looking stunts, special effects, and in general unique looking shots, devices and ‘looks’ in my movies. Of course stunts and special FX may not be your cup of tea when it comes to making or watching a film, and this is fair enough. If a dialogue laden script and endless two shots and close-ups take your fancy, then I’m sure you don’t need to be told how to achieve this. It is simply a matter of writing the script, then setting up the camera and shooting it, generally speaking. However when it comes to low budget film making these days I feel that the film maker must make a special effort to produce a movie that is unique and interesting for an audience to experience. This does not necessarily mean that the film maker must load the film with cheap stunts, blood and guts to grab an audience’s attention. However they should at least try to create something that is very original and makes the audience question how they achieved the results that they did, even if the movie does consist of only ‘two shots’ and ‘close-ups’. In the case of this type of movie (two shot/close-up style), the obvious place to start with ‘creative thinking’ is when writing the script. However this should be fundamental to any script, story or idea. First of all, whoever you are, you must realise that it isn’t money that makes a good film, it is the idea and how that idea is achieved in creative ways. Of course it’s a great thing if you do have a little bit of money to put towards a film, however, throwing around creativity will always win over throwing around a ton of cash at a film, I believe anyway. You probably already have realised this, but for the uninitiated, this is the core theme of this paper; use your creativity where possible, not your money.
Physics, Roller Coasters
Part 1 Roller coasters Additional notes: GPE = m x g x h KE = m x v? The main energy transfers that happen as a car travels along the track from the start of the ride to the end: [1]The rollercoaster car gains gravitational potential energy (GPE) as it travels to the top. Once over the top, the car gains speed as GPE is transferred to kinetic energy (KE). As it travels to the top of another loop, KE is transferred to GPE. Not all the energy is transferred to or from GPE – some is transferred to the surroundings as heat and sound.All moving objects have kinetic energy, KE. The kinetic energy an object has depends on the mass and speed. If the mass doubles, the KE doubles and if the speed doubles, the KE quadruples. Normally energy is lost through sound and heat (friction, air resistance). How the heights of the hills are designed to allow an empty car to reach the end of the ride: [2]The hills are designed so that it is low enough that the momentum of the car from the previous drop carries it up and over the hill.This is why the hills are usually lower towards the end of the ride, because the car has lost momentum due to friction and air resistance. Mainly the consecutive hill must be lower as it will not have enough energy because some of it is lost and sound and heat. Therefore, if the car was to reach the end of the ride, the height of the hills must be lower each consecutive time. How the energy transfers determine the heights of the hills: [4] After the roller coaster is drops from the first hill it does two things with its energy.First, it begins to transform that energy from one form to another–from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy incre ases. Each time the roller coaster goes uphill, its kinetic energy decreases and its gravitational potential energy increases.But each transfer of energy isn't complete because some of the energy is lost to heat and sound. Because of this lost energy, the roller coaster can't return to its original height after coasting downhill. That's why each successive hill must be lower than the previous hill. Eventually the roller coaster has lost so much of its original total energy that the ride must end. With so little total energy left, the roller coaster can't have much gravitational potential energy and must be much lower than the top of the first hill.This is why the hills must be a certain height, in order to transfer enough GPE into KE.

Baby Dumping
Today, in our society, every age, they need to deal with the problem. An era of some of the problems may be different from another era problem, it could be the same. High school students, especially in the face so many problems. Five issues high school students face these days, illegal racing, use of drugs and alcohol abuse, free sex, abortion and baby dumping. Problems usually follow the flow, first racing, it is usually held in the evening, of course, it is troublesome to other road users. In addition, it can also be deadly man. After the game, they will usually go to a nightclub. It is they start drugs, become addicted to alcohol places. When they are under the influence of drugs and alcohol, which will cause them to have an unprotected sex, which means that sex did not take any preventive pregnancy. High school students are too immature to fully understand the impact of no sex, it is possible for their lives. Therefore, there is no doubt, because that would create another problem. For a given problem is abortion and baby dumping. Unintended pregnancy scare, aborted babies before they take risks, their families know that physical changes after. Abortion is a dangerous act, which may be fatal mother. But in a desperate situation like this, they can not rationally think. But not everyone has enough intuition, abortion to take the risk. Some of them decided to give birth to a baby, but then the end of it, for some reason, they dumped the baby did not hesitate. Dump the baby means that they throw away after the baby is not in any place to take care of it. Typically, the baby is in a dump after they were born. In most cases, the baby was already dead when they find someone else. Baby Dumping Today, in our society, every age, they need to deal with the problem.

Perspectives ISO 9000, service quality and ergonomics Stanislav Karapetrovic 1. Introduction In the last decade or so, we have witnessed an explosion of quality-related standards and regulations.As a result of the continuous quest for better â€Å"quality†of products and services offered to customers, the International Organization for Standardization introduced the ISO 9000 series of quality management and quality assurance standards in 1987. The series currently includes three models for quality assurance (ISO 9001, ISO 9002 and ISO 9003), guidelines for quality management (ISO 9004), and two supporting documents: ISO 9000 Guidelines for Model’s Selection and Use and ISO 8402 Quality Vocabulary (Figure 1). The ISO 9000 standards have been accepted worldwide, with more than 200,000 organizations already registered.The standards present a sound basis for assuring the customer of quality of products and services, as well as the processes that create them. Several other quality-related standards have since emerged, such as the automotive standards QS 9000, environmental management standards ISO 14000, and emerging health and safety international standards (Figura, 1996). The upcoming revision of ISO 9000 standards in the year 2000 (now in the form of a Technical Committee Draft) is expected to further facilitate the use of quality assurance methods the world over.Another commonly used phrase from the 1980s and 1990s has been total quality management (TQM): an integrated approach to the management of quality with special emphasis on delighting customers and improving the wellbeing of all employees in the organization. A number of articles have been written on the relationship between the ISO 9000 series and TQM (Johnson, 1993; Struebing, 1996; Wilson, 1996; Velury, 1996; Corigan, 1994; Sakofsky, 1994; Emmons, 1994), underlying the opinion of quality management professionals that the two are not quite the same.While ISO 9000 series are technical, presenting speci?cations, requirements and guidelines for quality systems, TQM emphasizes teamwork and customer satisfaction. Put another way, TQM is quality management with â€Å"a human touch†. Does this mean that ergonomic aspects of the workplace and customer satisfaction are not emphasized by ISO 9000? Does quality assurance (ISO 9000) emphasize ergonomics and 81 The author Stanislav Karapetrovic is based at the Department of Industrial Engineering, Dalhousie University, Halifax, Nova Scotia, Canada.Keywords Ergonomics, ISO 9000, Quality assurance, Service quality, Workers Abstract This paper addresses some ergonomic issues in the ISO 9000-based qualit y assurance.

In the present time of globalization of markets and internationalization of best-practice standards, such questions can and should be posed. This paper addresses some of the ergonomic issues in the ISO 9000-based quality assurance. Ergonomics, that is the study of human factors in engineering and design of systems, is brie?y touched on.Then, outlines of ISO 9001 and ISO 9004 quality system models are provided, and all 20 requirements of the current ISO 9001:9004 standard are presented in an ergonomic light. Subsequently, human factors in the documentation and implementation of a quality system are illustrated. The relevance of ergonomic studies in the development of service systems is addressed. Finally, the design of an ergonomic assurance system based on ISO 9000 is discussed. 2. Ergonomics It seems that it takes a disaster, loss of human life, or a health crisis for most of us to realize how important human factors are.Before the Three Mile Island incident, the Chernobil explosion, the Bhopal pesticide leak, plane crashes involving human errors, or ?ndings that millions of people suffer from repetitive stress injuries, it would have been hard to ?nd anyone who knew what ergonomics or human factors engineering are (not including the ergonomists themselves, of course). Today, however, we often hear about â€Å"ergonomicallydesigned computer mouse and keyboard†, 82 â€Å"ergonomic†chairs, pots, pans, door handles, and automatic teller machines (ATM).We now know that ergonomic design of products and processes is bsolutely crucial for effective and ef?cient work. Ergonomics, or human factors engineering, deals with the design for human use, as well as optimizing working and living conditions (Sanders and McCormick, 1993). The ?rst term (ergonomics) is mainly in use in Europe, while the second (human factors engineering) is often heard in North America. Th e following de?nition, modi?ed from Chapanis (1985), is provided: Ergonomics discovers and applies information about human behavior, limitations, abilities and other human characteristics to the design of systems for ef?cient, safe, comfortable and effective human use.Interested readers are referred to a classic in ergonomics, Sanders’ and McCormick’s â€Å"Human factors in engineering and design†(1993), for more information on the history of the science and a detailed study of many applications of ergonomics. Ergonomics, almost by default, is implied in quality assurance. Quality assurance encompasses techniques used to provide con?dence to customers that their requirements for quality are met. Therefore, by de?nition, human factors are involved. Assurances in the quality of products and services are provided to humans, by humans.In fact, ergonomics and quality assurance are so intertwined that it is impossible to say where one starts and the other ends. Sever al articles in ergonomics literature have already discussed the use of quality assurance techniques in human factors engineering (for instance, see Helander and Burri, 1995; Bergquist and Abeysekera, 1996). For an early account on human factors in quality assurance, the reader is referred to Harris and Chaney (1969). Hence, in the following sections, interrelationships between ergonomics and quality assurance will be addressed. 3.Quality Assurance (ISO 9001) and Management (ISO 9004) Of the three available models for quality system registration, ISO 9001 is undoubtedly the most comprehensive and most widely used. The current version (ISO 9001: 1994), includes 20 elements (requirements), to which a quality assurance system of an organization is assessed (Table I). ISO 9001 covers design, development, production, installation and servicing activities. It is aimed at providing con?dence to internal and external customers that their requirements for quality are continuously met.An organ ization’s anagement is the main internal customer, while external customers include consumers of the organization’s products and services, as well as registrars that assess the suitability and effectiveness of the quality system. ISO 9001 is a generic standard, which means that it is universally applicable to both manufacturing and service organizations, i. e. small businesses (Karapetrovic et al. , 1997), health care and education (Willborn and Cheng, 1994). Rather than focusing on speci?c products and services, ISO 9001 addresses quality systems and processes in?uencing the product throughout its lifecycle.A quality system can be de?ned as a set of processes that function harmoniously, using various resources, to achieve quality objectives (Karapetrovic and Willborn, 1998A). It is in the interaction of human, material and information resources, as well as human resources and processes, that the ergonomic aspects of the quality system emerge. Focusing on the underlyin g concept of a system will help us understand the interrelationships between the quality and ergonomic system, and provide a possibility for integration.Apart from ISO 9001, a set of guidelines numbered ISO 9004 is widely used for developing and implementing quality 83 management. The set currently consists of eight documents, ranging from the guidelines on quality management in service organizations to con?guration and project management. For the purpose of discussing an ergonomic system in services, we turn our attention to the second document in the series, namely the ISO 9004-2 (1994) â€Å"Quality management and quality system elements: Guidelines for services†).In essence very similar in scope and structure to ISO 9001, ISO 9004-2 provides guidelines for establishing quality management throughout the service life cycle, starting from establishing the need for a service, through service design, acquisition of resources, service delivery and status, as well as performance analysis and improvement. Differing from ISO 9001, these guidelines directly address interfaces with customers, including â€Å"creating a perception of the appropriate image based on the reality of actions taken to meet customers needs†(ISO 9004-2: 1994).Effective communication with customers, â€Å"listening to them and keeping them informed†, is particularly emphasized. What is also important from an ergonomic standpoint is that the guidelines provide the basis for adequate training of personnel, including motivation, staff development and communication. Although the training mentioned therein mostly involves â€Å"quality system training†, it could be expanded to environmental, health and safety, and ergonomic system training.For different strategies of using the quality system framework for developing other management systems, including environment and ergonomics, the reader is referred to Karapetrovic and Willborn (1998B and 1998C). In addition to ISO 90 04-2, another standard from the ISO 9004 series, namely ISO 9004: Part 1 â€Å"Guidelines for quality management and quality system elements†, addresses some particular ergonomic aspects. This is done in the standard’s 19th element: Product safety. Speci?cally, it is suggested that â€Å"consideration be given to identifying safety aspects of products and processes with the aim of enhancing safety†(ISO 9004-1: 1994).Steps to achieve this can include: †¢ identifying relevant safety standards; †¢ performing design evaluation tests for safety; †¢ analyzing instructions and warnings to the user; Table I Ergonomic issues and implications of ISO 9001 (1994) ISO 9001 element 4. 1 4. 2 4. 3 Management responsibility Quality system Contract review Ergonomic issues Organization ensures that the quality policy is understood at all levels Procedures and work instructions are effectively documented/implemented Customer requirements are adequately de?ned and d ocumentedImplications Quality system documentation should be designed and implemented using ergonomic (human factors engineering) knowledge Ergonomic characteristics of a product, such as environmental conditions, sensory characteristics proper handling and packaging should be determined (see Bergquist and Abeysekera, 1996; Helander and Burri, 1995; Barsky and Dutta, 1997) Products should be ergonomically designed to ensure healthy and safe functioning Quality system documents should be accessible . 4 4. 5 Design control Document control 4. 6 4. 7 4. 8 4. 9 Purchasing Control of customer supplied product Product identi?cation and traceability Process control 4. 10 Inspection and testing 4. 11 Inspection and test equipment 4. 12 Inspection and test status 4. 13 Nonconforming product 4. 14 Corrective and preventive action 4. 15 Handling, storage, †¦, delivery 4. 16 Control of quality records 4. 17 Internal quality audits 4. 18 Training 4. 19 ServicingCrucial characteristics for s afe and proper functioning of the product are identi?ed Appropriate documents are readily available at all locations where essential operations are performed Purchasing documents adequately address speci?ed requirements Adequate procedures for storage and maintenance of the product are in place Product is adequately identi?ed and traceable Suitable equipment and working environment are used Criteria for workmanship is stipulated in the clearest practical manner Records clearly illustrate the results of inspection and testing activities Suitable indicators of calibration status are identi?ed Inspection and test status of the product is identi?ed by suitable means Nonconforming products are adequately identi?ed and segregated Appropriate sources of information are used to detect and eliminate potential/ existing causes of defects Adequate handling, storage, packaging, preservation and delivery of the product is identi?ed and maintained Quality records are adequately identi?ed, indexed , ?led and storedQuality records are easily accessible Quality audits are performed to examine the suitability and effectiveness of the quality system Training needs are identi?ed and adequate training provided Appropriate identi?cation of servicing needs and customer feedback is performed Ergonomic techniques can be used to ensure clear understanding of documents Safe and risk-free storage and maintenance of products is emphasized Identi?cation of products should be performed according to ergonomic guidelines regulations For identi?cation and maintenance of the suitable working environment and hardware, ergonomic analysis and evaluations must be performed Identi?cation of products and equipment should be performed according to ergonomic guidelines and regulations (for example, see Sanders and McCormick, 1993 (part 2), and Harris and Chaney, 1070 (chapters 6-11)Ergonomical analysis of human-information interaction is helpful (for instance, see Sanders and McCormick, 1993 (part 2) Er gonomical design and analysis of handling and packaging of products should be used Ergonomic techniques can be used to ensure clear understanding of documents, and accessibility of records Ergonomic audits/evaluations, identifying areas for possible improvement of human-machineproduct-environment interactions are performed Ergonomic training should be emphasized Ergonomic characteristics of a product, such as environmental conditions, sensory characteristics proper handling and packaging should be determined (see Bergquist and Abeysekera, 1996; Helander and Burri, 1995; Barsky and Dutta, 1997)Statistical tools and techniques are used in ergonomic analysis and evaluations 4. 20 Statistical techniques The need for the application of statistical techniques is identi?ed 84 †¢ developing a means of product traceability to facilitate product recall; †¢ considering development of an emergency plan The following section will address some ergonomic factors in the ISO 9001/9004 qual ity system structure, as well as suggest implementation of this system with ergonomics in mind. 4. Ergonomic considerations of ISO 9001/9004 Quality systems depicted in ISO 9001 and ISO 9004 standards apply to all phases in the life cycle of a service, from initial identi?cation to ?nal satisfaction of customer requirements.The concept of all activities in?uencing the quality of a service throughout its life cycle is often referred to as the â€Å"service quality loop†(ISO 9004-2, 1994). Thus, a service quality system involves three main elements: (1) service; (2) processes along the quality loop; and (3) resources. Likewise, ergonomic considerations within a service quality system include: †¢ Ergonomic design and delivery of service (and/or related products). †¢ Ergonomic design and application of processes. †¢ Analysis of the interaction between human and information/material resources Using Figure 1, it is possible to explain how quality and ergonomics inte rrelate in a quality system. Each product or service made possesses certain characteristics.For example, service quality is a set of characteristics that bear on the service’s ability to satisfy customer requirements. Ergonomic characteristics of products / services provide safe, healthy and ef?cient usage and/or delivery. It is evident that some ergonomic characteristics of a product (or service) are essentially quality characteristics (such as the design of the driver’s seat in a car), and vice-versa. Also, service delivery processes have to satisfy certain requirements that may be ergonomic in nature. For example, the environment in which retail-banking services operate may be altered to provide safety for a bank teller working in it. Finally, ergonomic issues emerge when human, material and informa85 ion resources are combined to create a quality system.The current ISO 9001 quality system has a multitude of elements that are directly applicable to managing ergonomi cs and health/safety. Table I lists all 20 elements of ISO 9001 in the order in which they appear in the standard, illustrates sections and speci?c requirements which pertain to ergonomics, and provides ergonomic implications of the quality system. The implications range from adequate identi?cation of customer ergonomic requirements, ergonomically suitable design of products, services and processes, to identi?cation and maintenance of appropriate working environment and equipment.Such analysis of the ISO 9001 quality system shows that virtually every element of the system includes at least some ergonomic and/or health and safety aspects. This conclusion, however, is not surprising, since ultimately, quality is created by people, and for people. Not only does the content of ISO 9001 relate to human factors (Hansen, 1996), but also its context. A quality system must be adequately documented and implemented in order to operate effectively and ef?ciently. Quality documentation, as a pil lar of the quality system, must be understood and readily available to all persons whose work affects quality, as well as understood by all involved. Ergonomically designed documentation will undoubtedly help people understand their tasks better and improve their performance.New technologies, such as head-up-displays (Geiselman and Osgood, 1995; Karapetrovic, 1995), computer-aided communication (through electronic mail and the Internet) can greatly improve the implementation of a quality system in any organization. Examples include: †¢ Operators using HUDs for display of quality procedures and work instructions. †¢ Paperless ISO 9000 documentation, i. e. documents available on-line using HTML or Java (Clarkin and Dow, 1997). †¢ Wireless electronic mail for reporting and analysis of quality-related problems. The following section addresses the implementation of human factors engineering in services, using ?nancial services as an example, in more detail. 5. Ergonomics a nd services How do ergonomics relate to service quality systems?To answer that question, we can follow the above-mentioned â€Å"service quality loop†from the inception of the need for service, to the evaluation of whether that need has been satis?ed. In designing a â€Å"quality service†, we must ?rst identify the need for it, as well as ?nd out who would actually need such a service. Put another way, we are de?ning the user and his/her needs. For instance, say we want to open a bank branch in a specific location. Do local bank users really need a branch there? What exactly do they need? Perhaps they need investment services, or easy access to cash, or mortgage consultations. Sanders and McCormick (1993) and Bailey (1982) de?ne the identi?cation of user needs through observation, interviews and questionnaires as ergonomic activities that apply here.Psychology-based tools of ergonomics deal in particular with an effective and ef?cient determination of user needs. The service system is subsequently designed on the basis of identi?ed needs. We have determined that local users require access to money from their accounts as well as the possibility of discussing investments. Now, we need to allocate resources to required banking functions. These resources include people (bank employees), hardware (automatic teller machines (ATM), computers) and software. Which particular functions should we assign to people, and which to machines? For instance, for easy access to cash, we would assume that a 24hour ATM would be appropriate.However, what if most of the bank’s clients are seniors, who are still not accustomed to trusting machines in dealing with deposits or withdrawals, or if the bank is located in a place where people prefer customer service and contact with bank tellers rather than machines? Ergonomic studies help us in determining speci?c capabilities of people, hardware and software, and can provide signi?cant assistance in allocating system functions. Then, we can decide whether to completely automate certain functions, or to assign people to perform them, or use both machines and people. For example, a bank may decide to allow withdrawals of less than $1,000 from an ATM. If a customer wants to withdraw more than that, he/she would have to go to a bank teller. 86Once we have decided which resources the bank should have (say three ATMs, four tellers and two investment advisors), we need to perform an analysis of the required processes, activities and tasks. Put another way, we are listing the sequence of activities that need to be conducted in order to accomplish a speci?c function. Flowcharts are particularly helpful here. For instance, we can specify a procedure for cash withdrawals from the bank. This, in ergonomics, is called task description and analysis (Sanders and McCormick, 1993). Whenever we have some interaction between people and hardware or software, such as when a teller needs to input withdrawal informat ion into the database, there are ergonomic implications.For example, in the bank where I normally do my ?nancial transactions, computer monitors and keyboards are placed so low in relation to the counter, that the teller needs to bend down every time he/she inputs the information, virtually disappearing behind the counter. Just imagine how many times the teller needs to bend like that every day, every week, every month. Put another way, in designing the work space for employees, e. g. placing customer service counters and computers in determined locations, allocating space for safety deposit boxes, etc. , we inevitably in?uence the comfort, safety and ef?ciency of people working in such spaces. All these are ergonomic considerations that can in?uence the quality of the product or service.The likely reason why tellers in my bank still have to bend down to reach the computer is that it was probably never de?ned as a problem at all. The existence of an ergonomic program within the bank , with planned ergonomic audits and corrective actions, would certainly identify and rectify such a problem. But how can such a program be introduced with minimum cost and maximum bene?ts? Perhaps the solution is in the integration of the existing quality system with an ergonomic program. The integration of quality and environment management systems came naturally, since standards representing best practices were effectively established at the international level (namely ISO 9000 and ISO 14000).This should also be the case with occupational health and safety (OHS), since national and international OHS standards, dubbed ISO 20000 (Figura, 1996) are already emerging. The following section presents an approach to the development of an ergonomic assurance system on the basis of the quality system. 6. Ergonomics assurance system As was mentioned in Section 3 of this paper, the systems concept can greatly assist us in understanding the interrelationships of many production and management processes, among others, quality and ergonomics. For an excellent account of the relationship between ergonomics and the system design, the interested reader can refer to Sanders and McCormick (1993), Chapter 22. While the pplication of the systems concept to service quality is presented elsewhere (Karapetrovic and Willborn, 1998A), it can be used to propose an ergonomic assurance system. We can de?ne ergonomic assurance as â€Å"all those planned and systematic actions aimed at providing con?dence to customers, management and the general public, that their requirements and needs for ergonomically safe products and processes are met†.An ergonomic assurance system is then a â€Å"set of processes and resources that function harmoniously to achieve objectives related to ergonomic design and implementation of products and processes†.Note: Proposed EAS elements are given in bold letters, while numbers represent sections of the ISO 9004-2 Guidelines 87 Similarly to the ISO 14001:1996 environmental management system, an ergonomic assurance system can include Deming’s plan-dostudy-act (PDSA) continuous improvement circle, with the following elements: †¢ Ergonomic objectives. †¢ Planning and design (ergonomic aspects, targets, determination of system performance speci?cations, ergonomic system design). †¢ Resource acquisition and deployment (allocation of functions to people, hardware and software; task analysis, design of jobs and human-hardware-software interfaces; training). †¢ Operation (ergonomic control, monitoring and measurement).†¢ Corrective/preventive action (ergonomic audits). Improvement (ergonomic evaluations, communication with interested parties. Interested parties may include customers, for ergonomic characteristics of the product/service, and employees, for ergonomics of the workplace). Rather than adding speci?c ergonomic and safety requirements to existing quality standards (Barsky and Dutta (1997) sugg est this), a separate ergonomic system standard can be drafted, and then integrated with existing quality management systems. Using the de?nition and the model of a quality system from Karapetrovic and Willborn (1998C), proposed elements of the ergonomic management system (EMS) can be illustrated as in Figure 2.For example, the executive management of an organization should de?ne an ergonomic policy that is documented and communicated to all employees. Ergonomic aspects of all activities and processes within the organization should be identi?ed and speci?c objectives and targets set. An ergonomic management program should be de?ned and documented, and adequate resources allocated. Operation of the EMS should include a statement of responsibility and authority of people involved, identi?cation of training needs and a provision of adequate ergonomic training, and preparation of adequate EMS documentation. Corrective and preventive action to eliminate existing and potential problems sh ould be undertaken, and ergonomic audits would assist in this effort.Finally, the executive management should review the status of the EMS, includ88 ing its effectiveness, suitability, and conformance to the requirements. 7. Conclusion This paper addressed some of the ergonomic issues in the ISO 9000-based quality assurance for services. Outlines of ISO 9001 and ISO 9004 quality system models were provided, followed by a discussion of the content of the ISO 9001 standard considering ergonomics and human factors. Ergonomic implementation of a quality system was subsequently addressed. Finally, possible development of an â€Å"ergonomic assurance system†on the basis of ISO 9001 and systems theory was presented. Further research into the development of ergonomic assurance systems is suggested.

Nature in Literature
Nature plays a huge role in many pieces of literature, but especially Basho’s Narrow Road to the Deep North and Voltaire’s Candide. There is a major difference between the two forms of literature and how nature is incorporated into each. This Japanese form of literature has a much lighter tone than that of the European style of literature. You can see a calmer, more relaxed intention into the nature that is in Basho’s Narrow Road to the Deep North.On page 413 in Basho’s piece, it says â€Å"As the year gradually came to an end and spring arrived, filling the sky with mist, I longed to cross the Shirakawa Barrier, the most revered of poetic places. †From this section, you can see that Basho gets his inspiration for his literature and poetry from the places that he travels, and this resulted in his linked-verse sequence. Even though Basho had a long, tough journey of travels; the nature takes his breath away. On page 416 of Narrow Road to the Deep No rth, it says â€Å"my body and spirit were tired from the pain of the long journey; my heart overwhelmed by the landscape. †This statement shows that regardless of the struggles, he could find a poetic sense in everything he went through. In Narrow Road to the Deep North, Basho also found religion to accompany the bright nature in his literature of his travels. On page 418, Basho writes, â€Å"the green of pine is dark and dense, the branches and leaves bent by the salty breezeâ€â€as if they were deliberately twisted.
