The worker who is responsible for Airless Pump maintenance have a high possibility to suffer from WMSDs, because a height of Airless Pump workbench is too low. In this paper, I'm going to introduce a research about 1) analysis of working environment through a interview with an actual field worker, 2) Ergonomic simulation modeling of an Ariless Pump worker to suggest a advanced working environment and a working instructions. I have used a DELMIA S/W as a tool for ergonomic simulation and performed a posture & activity to analyze a RULA methodology. Applying the Digital Human Simulation to analyze working posture would be helpful to preventing WMSDs.

To take maximum advantage of computers without compromising the health of library staffs and users, it is important that the computer workstation be adapted to the needs of the users. While the topic of occupational safety and health is a major industry concern, it is not commonplace in libraries. Therefore, this study is to apply the ergonomic principles to library computer workstations and suggest the ergonomic models for computer table and chair, monitor and keyboard placement, posture and motion. lighting, and other environments.

Shipbuilding workers are potentially exposed to ergonomic hazards in the manufacturing process. The purpose of this study is to describe the impact of an ergonomic intervention and the implementation effect of ergonomics program at a shipbuilding company. This study portrays an implementation procedure of ergonomics program over a period of two years concerning ergonomic hazard analysis and improvement, along with medical management. After implementation of the ergonomics program, the productivity improved, and the rate of accidental incidents decreased, also the loss of workdays decreased largely. The implementation effect of ergonomics program presented in this study can be used to provide baseline information for the prevention of musculoskeletal disorders in the shipbuilding industry.

Work-related musculoskeletal hazards in a paper-making industry were examined to explore ergonomic interventions in a participatory approach for mitigating the hazards. Manual tasks occurred in this paper-making industry were quite different with ordinary assembly industry where individual workers perform certain specified tasks repetitively. Workers used to perform varieties of team-based irregular manual tasks to interact with the facilities. Among 96 manual jobs investigated, 44 potential hazardous jobs were screened during basic investigation phase and finally 16 hazardous jobs were identified by the detailed analysis phase. The major hazardous factors were awkward postures and excessive weights. Possible ways of intervention were developed, reviewed and proposed by an ergonomics team comprised of staffs and engineers from various departments and ergonomics specialist from outside the company. The proposed intervention ideas were evaluated and modified by the workers and union representatives in terms of usability and comfort. Implemented interventions including mechanization, automation, and improvement of tools and equipments provided fairly promising results.

The goal of this study is to propose the improved scheme that prevents the workers against musculoskeletal disorders at a fishcake manufacturing company, A questionnaire and an ergonomic assessment method were adopted to analyze the symptoms of workers' musculoskeletal disorders, and an analysis of working postures and a quantitative assessment on various processes were performed to find out harmful factors of workplace. Based on the result of the evaluation, to enhance the working environment, improvement of worktable, working space, tools, and outfit was suggested, and induction of mechanical system was also suggested. Suggested improvement plan was applied to the workplace step by step and it is confirmed that improvement plan can removes the injurious factors of musculoskeletal diseases effectively.

Recently, both management and labor are interested in the increasing ratio of musculoskeletal disorders. And the developed countries make efforts to consider a counterplan such as prevention activity of musculoskeletal disorders and application possibility of ergonomic program, because musculoskeletal disorders take large portion out of occupational disease. Especially, small and medium enterprises have bigger problems due to the inferior work condition and environment in comparison with big businesses. This study is to introduce developed countries' cases such as WISE(Work Improvement in Small Enterprises) and OSHA Handbook for Small Businesses and to suggest the program of ergonomic management for small and medium enterprises having comparative difficulties against big businesses in improving work environment and managing ergonomic operations.

In this paper, we propose the ergonomic design method in shape design applicable for Advanced Urban Transit System. Human's sensitivity and User Interface of rolling stock investigated ergonomic studies of several type. The sensibility engineering design made approach of user center design in rolling stocks design. Therefore, we have application to properly of ergonomic design element in rolling stock design. we expert visual design and user interface help greatly in excellent rolling stock design.

A control panel layout method based on the constraint satisfaction problem(CSP) technique was developed to generate an ergonomically sound panel design. This control panel layout method attempts to incorporate a variety of relevant ergonomic principles and design constrains, and generate an optimal or, at least, a "satisfactory" solution through the efficient search algorithm. The problem of seeking an ergonomically sound panel design should be viewed as a multiple criteria problem, and most of the design objectives should be understood as constraints. Hence, a CSP technique was employed in this study for dealing with the multi-constraiants layout problem. The efficient search algorithm using "preprocess" and "look ahead" procedures was developed to handle the vast amount of computational effort. In order to apply the CSP technique to the panel layout procedure, the ergonomic principles such as spatial compatibility, frequency-of- use, importance, functional grouping, and sequence-of-use were formalized as CSP terms. The effectiveness of the developed panel layout method was evaluated by example problems, and the results clearly showed that the generated layouts took various ergonomic design principles into account.esign principles into account.

This study concerns with an ergonomic approach for improving the workplace of an air-conditioner factory. If work tasks and equipments do not include ergonomic principles in their design, workers may have exposure to undue physical stress, strain, and overexertion, including awkward postures, forceful exertions, repetitive motion, and heavy lifting. The purpose of this study is to improve the safety, comfort, and efficiency of the workplace. Adapting tasks, work stations, tools, and equipments to fit the worker can help reduce physical stress on a worker's body and enhance the effectiveness and efficiency of workplace.

The main objective of this study is to quantify the appropriateness of the sensibility vocabularies used in sensibility ergonomic evaluation scheme by applying structural equation model. In the conventional sensibility ergonomic evaluation scheme, factor analysis is employed to classify various vocabularies into some common factors. However, since the vocabularies were chosen quite subjectively, it is difficult to ascertain that they represent the product attributes properly. It was shown in a case study that the structural equation model provides the quantitative results to verify whether the selected vocabularies are eligible for further steps of sensibility ergonomic evaluation.
