정비작업에 대한 인체역학적 분석및 작업 자세 분석

Although the tasks are being mechanized or automated today, many taks are still performed manually in serveral indeustrial settings and low back pain has been a social and economic problem. In this study, five machine repair tasks are selected from one manufacturing company in Pohang, which are accountable for relatively high complaints of low back pain. The purpose of this study is to quantitatively evaluate the hazards of the tasks, and finally to recommend the improved methods and guidelines for safe work practices. For most of the tasks under study, workers were found to be exposed to relatively high stresses in low back, mainly due to the heavy objects handled and the improper working postures.
