연구개발작업자의 인간공학적 작업환경개선에 관한 연구

Abstract

The aim of this study is to determine the risk factors of work-related musculoskeletal disorder of researchers and developers in Hi-Tech industry, through questionnaires and field observation. A sample of 140 R＆D workers was chosen to respond the questionnaire, which was designed to investigate musculoskeletal symptoms and work-related discomfort. Field observation involved video recording of twelve tasks, characterized by a representative work model. For job hazard assessment, the following methodology has been applied OWAS for classification of working postures, RULA for assessment of work engaging the upper body, and REBA for assessment of work engaging the whole body. The results of the questionnaires indicate that researchers and developers complain acutely of poor work environmental physical strain. It was observed through job hazard assessment according to varying manual handling lifting, carrying, inspection, and PC work. Results drawn in this study could be used to provide baseline information for improvement of research and development working environment in Hi-Tech industry and to prevent musculoskeletal disorder.
