Each year, the accidents were increased during the practices in Industrial high school. Especially, electricity is important in laboratory of industrial high school because many students used electrical equipment. A survey was conducted in industrial high school to know the states of electrical equipment and education. The survey form was administrated to 80 students and teachers in industrial high school. The data were analyzed in terms of the safety degree of electrical equipment, frequency of safety inspection, frequency and contents of electrical safety education, and concerns of head master in industrial high school. Successful strategies for accident prevention depend on effective analysis.

VDT증후군 예방을 위한 사무실 작업자들의 VDT 작업조사와 예방대책에 대한 연구
김유창,홍창우 동의대학교 산업기술개발연구소 2005 産業技術硏究誌 Vol.19 No.-
VDT(Visual Display Terminal) workers are increasing relatively according to moving from the manufacturing industry to service industry in industry structure owing to developing an info-communications. Office workers who sit work in front of the VDT for most of working time are exposed to the new risk of industrial accident occurrence such as musculoskeletal disorders, fatigue, visual disability caused the VDT work. Now work related musculoskeletal disorders(WMSDs) are issue in manufacturing industry such as shipbuilding and automobile and studies actively are in progress about it recently. While WMSDs related to the VDT work are approved of only special work, an example, a telephone operator, as industrial accident, systematic studies are short about it. It is expected for WMSDs related to the VDT work to increase rapidly because of spreading the superspeed internet and be a social problem in the future. Therefore, it is necessary to be prepared. In this study, a questionnaire about the status of the VDT work in office workers was implemented and results from that were used as a data to develop a VDT syndrome preventive program in the office work.

근골격계질환 예방을 위한 인간공학적 농작업 개선 지원시스템 개발
김유창;장은준 東義大學校産業技術開發硏究所 2010 産業技術硏究誌 Vol.24 No.-
The agriculture in Korea has seen rapid growth in its elderly population compared with other industries. Occupational injury rates of agricultural worker are very high in Korea. Until now there isn't preventive measure for agricultural worker because mostly preventive activity of occupational injury focused to the worker of manufacturing industry. Recently, Korea government starts to conduct several interventions for the improvement of agricultural work. So we need the ergonomics support system to match the characteristics and the ability of agricultural worker for the improvement of agricultural work. So this study proposes the development of an ergonomics support system foe the improvement of agricultural work.

Objectives : To report cubital tunnel syndrome due to repetitive motions. Methods : A worker complaining muscle weakness and atrophy of the right hand intrinsic muscles admitted to a hospital. We evaluated him with blood tests, neurophysio-logic studies (NCV & EMG), plain X-ray and US at the both elbows. We investigated his occupational history, and videotaped his work motions based on the work cycle at his previous work site. Finally, an ergonomics expert analyzed the motions using rapid upper limb assessment (RULA). Results : NCV & EMG studies reveals slow conduction velocity on both ulnar nerve across the elbow, more severely in the right side. US shows us compatible finding with diffuse neuritis of both ulnar nerves at both elbows. RULA score is 7. Conclusion : We confirmed that the worker's symptoms were related to his previous jobs demanding repetitive motions using the elbow joints. It is necessary that we should prepare appropriate measures to evaluate, prevent, rehabilitate, and help injured workers to return to work.

Recently, work-related musculoskeletal disorders(WMSDs) are one of major issues in occupational safety and health in Korea Main risk factors of WMSDs include manual handling of heavy weight loads, awkward posture, repetitive tasks, prolonged static muscle contraction, and so on. The number of injured workers has rapidly increased and the related regulation was amended to improve the work conditions and environments. And demands for workers' compensation and improvement of work conditions and environment to prevent WMSDs have increasingly been raised. This study focused on managerial system to prevent WMSDs. Literal survey and questionnaire survey were accomplished to propose a management system in Korea for preventing WMSDs.
