Abstract

CTDs(cumulative trauma disorders) has recently increased at the workplaces in domestic and foreign countries due to repetitive actions or extreme movements. This paper is focused on ergonomic investigation and improvement for computer workplace, one of the electrical appliances manufacturing that are lots of highly simple, repetitive jobs. At the same time, this paper suggests the direction of improvement for prevention from MSD(musculoskeletal disorders) and back pain from the highly repetitive jobs. The whole workplace(including display and control device, workplace design, tools and facilities, work method, materials and its transportation, training etc.) can be improved through the diagnosis of working environment, its method, facilities and tools considering the ergonomic aspect. And increased safety and convenience, efficiency, freshness can simultaneously improve the productivity and convenience of jobs or at least maintaining the current productivity, the risk factor of jobs can be eliminated so that the convenience of jobs is improved. Comparison between before the Improvement through ergonomic investigation and after that results in the improvement of productivity and evaluation between before the improvement of jobs and after that using RULA(rapid upper limb assessment), one of the ergonomic risk assessment methods, results in the increased safety of jobs. Following study needs wide consideration to effect of improvement through ergonomic investigation uslng more assessment tools.
