The objective of this study was to identify risk factors associated with the occurrence of musculo-skeletal symptoms of cashiers and provide suggestions for an improved workspace design. Workload and exertion of each task were measured using job analysis and posture analysis. The three most time-consuming tasks were waiting (43.8%), scanning (23.5%) and payment transaction (22.9%). It was analyzed that the workspace can be improved by applying Korean anthropometric data to the design of the desk height. The most common posture was a standing posture with neutral back, and bent lower arms and hands. Finally, it was revealed that ``scanning`` and ``payment transaction`` seemed more stressful than other operations. The result of the ergonomic evaluation would be a useful basis for designing an improved workspace.

Objectives: Research on workplace violence has been conducted, but rarely has been organized systematically. In this study, we summarize the definition and classification of workplace violence studies and review the literature on workplace violence. Methods: Using academic search engines PubMed, Google Scholar and DBpia, we found 856 papers including “workplace violence” and “adverse social behavior” AND workplace in the title published until December 2018, and 208 papers were selected. The selected papers were classified by continent and country, year of publication, occupation, classification criteria of workplace violence, and research topic. Results: By country, the number of articles in the United States was the most with 40 (19.2%), followed by China 27 (13%), Korea 16 (7.7%), and Taiwan and Australia 15 (7.2%). By job category, healthcare workers accounted for the largest portion with 162 (79.0%) of the total, and 80 of them were conducted on nurses. Other occupations included civil servants, manufacturing workers, toll collectors and wageworkers. Among the classification methods of workplace violence, 147 (67.4%) articles were classified as type and there was a difference in the type of violence defined for each article. In the research topic, 114 (44.2%) articles analyzed the effects of workplace violence, and 105 (40.7%) articles describe the prevalence and characteristics of workplace violence, and 23 (8.9%) articles analyzing the causes of violence. Conclusion: The research topic is biased toward the field of healthcare, so it is necessary to expand to include various occupations or other specified occupations. It is also necessary to prepare appropriate measures against workplace violence.

Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

목적: 산재예방과 근로자의 건강증진을 위하여 대부분의 사업장은 산업안전보건 비용을 지출하고 있다 본 연구는 근로자 규모별 및 업종별 제조업 사업장의 산업안전 보건 비용의 규모 및 구성요소의 상대적 크기를 파악하여 제조업 사업장의 산업안전보건 비용의 수준을 제시하고자 하였다. 방법: 2005년도 동향조사에 참여한 제조업 사업장 중 근로복지공단의 2004년도 확정보험료 자료와 연결이 가능하였던 1,228개 제조업 사업장에 대하여 동향조사에서 파악한 8개 항목의 산재예방 투자비용과 산재보험료 자료를 이용하여 산업안전보건 비용을 계산하였다. 결과: 근로자 1인당 산업안전보건 비용은 근로자 5인 이상 50인 미만 사업장의 경우 99만원,근로자 50인 이상 300인 사업장 87만원 및 근로자 300인 이상 사업장 177만원이었다. 5인 이상 50인 미만 사업장과 50인 이상 300인 미만 사업장에서는 산업안전보건 비용중 산재보험료가 각각 62.8%와 52.8%로 가장 많았으며,다음으로 안전시설 및 보호장치 투자비로 각각 20.1%,19.1%이었다. 300인 이상 사업장에서는 산재보험료 37.5%,인력유지비 23.0%,안전시설 및 보호장비 투자비 22.8% 순이었다. 5인 이상 50인 미만 사업장에 비해 근로자 규모가 증가할수록 인력유지비,활동비,건강관리비 및 기타비용은 유의하게 증가하였으며,작업환경측정비와 산재 보험료는 유의하게 감소하였다. 결론: 2004년도 제조업 사업장이 지출한 산업안전보건 비용의 수준은 규모별 및 업종별로 매우 다양하였다. 산재 예방과 건강증진 측면에서 산업안전보건 비용에 대한 체계적이고 지속적인 접근이 요구된다. Objective: This study evaluated the cost for occupational health and safety in manufacturing factories in Korea according to the factory's size and the industrial classification. Methods: The costs to prevent occupational injuries and promote the general health of the workers were calculated by using the data of The Occupational Safety and Health Survey in Korea in the year of 2005 and the data of the Industrial Accident Compensation Insurance (IACI) Premiums at the same factories for the year of 2004. Results: The mean cost per one worker was as follows: 990,000 won for the factory with 5∼49 workers, 869,000 won for the factory with 50∼299 workers and 1,773,000 won for the factory with more than 300 workers, In the factories with 5∼49 workers and 50∼299 workers, the premium for the IACI was the largest portion of the cost (62.8% and 52.8%, respectively) and the cost for gear to protect workers from dangerous machinehes was the next biggest portion of the cost (20.1% and 19.1%, respectively). The largest portion of the cost in the factories with more than 300 workers was the premium for the IACI (37.5%). Conclusions: The investment costs to prevent occupational injuries and to promote the general health of the workers were very diverse according to the size of the factories and the industrial classification. To reduce the occupational injuries and to promote the general health of the workers, systematic and continuous approaches to evaluate the investment costs for the occupational health and safety are required.
