        근골격계부담작업의 적절성에 관한 연구

        천인애(Inae Chun),김유창(Yuchang Kim) 대한인간공학회 2020 大韓人間工學會誌 Vol.39 No.5

        Objective: The purpose of this study was to identify the problems and appropriateness of musculoskeletal burden work by industry, and to present the improvement direction and efficient implementation so that musculoskeletal burden work can be applied to the workplace. Background: The Ministry of Employment and Labor defined the scope of 11 musculoskeletal burden work in 2003. However, controversy continues over the appropriateness of musculoskeletal burden work. There are missing elements such as vibration, job stress, and a subjective load of workers in determining whether musculoskeletal burden work. Also, intermittent work with less than 60 days of work is not included in the musculoskeletal burden work. Method: This study was conducted a questionnaire of 127 safety manager, health manager, general worker, and administrative supervisor. Of the 127 respondents, 33.1% respondents were engaged in the manufacturing industry and 66.9% were engaged in the non-manufacturing industry. The main contents of the questionnaire are appropriateness and improvement direction of the 11 musculoskeletal burden work. Results: The results of the appropriateness of including a subjective load of workers to the evaluation method of musculoskeletal burden work were statistically significant differences by industry. The results of the appropriateness of the 11 musculoskeletal burden work were not statistically significant differences by industry except for No. 4, and 48.6% of respondents replied that the 11 musculoskeletal burden work were not appropriate. Conclusion: The 11 musculoskeletal burden work should be improved to include factors that can cause musculoskeletal disorders such as vibration and job stress. The intermittent criteria of musculoskeletal burden work need to be improved. In addition, by integrating musculoskeletal burden work No. 8 to 10 related to weight handling, it seems necessary to judge the degree of burden on a simple and clear criterion. Application: A subdivided criteria is needed so that the criteria for determining musculoskeletal burden work can be applied to various industries. The result of this study can be used as the basic data for research on the improvement of musculoskeletal burden work.
