모니터 공장의 인간공학 진단 및 개선에 관한 연구

Abstract

As factory automations are increasing in electrical appliance industries due to advanced technology these days, workers are repeatedly doing simplified jobs. CTD(Cumulative Trauma Disorder) is an occupational disease that can be found from workers who perform simple repetitive jobs on computers and assembly lines. In highly specialized today's industrial environment, continuous repetitive movement can cause an injury to muscle, articulation, blood vessel, and nerve. Accumulated minute injuries can cause CTD. Because workers in electrical appliance assembly jobs are often exposed to CTD due to repetitive process rather than the weight of products, working environment should be monitored and improved with concern. Workers' unnecessary actions, improper working position, tiredness, and irrational working processes can be corrected or improved by considering working environment from the ergonomic point of view and doing so can result in improving productivity, reducing defective ratio, and decreasing potential danger. Ergonomic Program Standard should be introduced to establish grades of danger and to control or prevent CTD from by both endeavoring constantly to enhance and monitor the improvement process. In this study, the actual state of working place and the methods in monitor factory are researched and analyzed from the ergonomic point of view and the suggestions for improvement are presented. The result of this study might be stretched to the ergonomic evaluation of similar industry and applied for improvement.
