    다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

    Workers employed in the agriculture industry have been exposed to many work-related musculoskeletal disorders. Therefore, our purposes in this study were to analysis and evaluate the physiological signal factors to improve musculoskeletal disorders in relation with farm work, especially. We investigated the physiological signal changes in the greenhouse such as body temperature, heart rate, blood pressure, physical activity, and heart rate variability. Moreover, we examined the lumbar spine loads of repeated lifting work related to farm work using the acceleration and angular velocity sensors. The changes of body temperature and heart rate as repeated lifting work during 30 minute were significant (p<0.05), and stress index was more than 80. Also, maximum shear force on the disk (L4/L5) of a lumbar spine in static state was present 500N, and maximum inertia moment was showed 139 N·m in dynamic state.
