Ergonomics Strategy Effects on Productivity and Occupational Hea

Ergonomics Strategy Effects on Productivity and Occupational Health Truama Care.
 Nayas Mustafa
Abstract
 You may have heard of the term Ergonomics . This is sometimes referred to as human factors . Not everyone really understands what ergonomics is, what it does, or how it affects people. This leaflet will help to answer these questions and to explain how understanding ergonomics can improve health and safety in your workplace. It is aimed at anyone who has a duty to maintain and improve health and safety and who wants to gain insight into ergonomics. It gives some examples of ergonomics problems and simple, effective advice on what can be done to solve them. Ergonomics is a science concerned with the fit between people and their work. It puts people first, taking account of their capabilities and limitations . Ergonomics aims to make sure that tasks, equipment, information and the environment suit each worker. An understanding of ergonomics in your workplace can improve your daily work routine. It is possible to eliminate aches, pains, and stresses at work and improve job satisfaction. Ergonomic solutions can be simple and straightforward to make - even small changes such as altering the height of a chair can make a considerable difference. People working in such poor or substandard environment are prone to occupational diseases. This may be mainly due to the attempts made by the workers to fit the man to the job rather than to fit the job to the man . The demands of new technologies and growing economies have led to the globalization of manufacturing, assembly and service industries. The globalization of the workplace and the multi-national configuration of organizations have created an environment for personnel and managers of constant change within the area of occupational and
environmental health in which safety, human factors and ergonomics play vital roles. Ergonomists, Safety and Human Factors Specialists and Industrial Hygienists often find it difficult to stay abreast of current information needed to stay in the forefront of important workplace issues. The most critical areas of concern are: communication, understanding, cultural differences and educational level of the workforce.

Effect of Weft Insertion Method of Weaving Machinery on Fabric P

Effect of Weft Insertion Method of Weaving Machinery on Fabric Properties Inequality in Width E. Mosaffa, M. Shanbeh, S. A., Hosseini
Abstract Nowadays technical fabrics are used in a wide range of applications like industry, transport, aviation and filtration. It is obvious that the properties of this kind of fabric in different parts have to be as much as possible the same. So the equal specification in width direction is totally important. As a result, in this paper we ve taken care of the inequality of some qualities such as air permeability, vapor permeability, breaking length and breaking strength; in width direction. It has to be mentioned that four kinds of shuttleless weaving machines were considered: airjet, waterjet, projectile and rapier. In the end, the obtained experiment data coefficient of variations compared. The results could be helpful to know which kind of shuttleless weaving machines would be better, with respect of the application.
 Keywords: inequality in width direction, air permeability, vapor permeability, breaking force, breaking length
