  • Occupational musculoskeletal disorders currently account for the largest proportion of the occupational illnesses in Korea. In this research, status of musculoskeletal disorders among the occupational illnesses was examined through workers' compensation claims data. Types and characteristics of musculoskeletal disorders were looked at other data set as well. The data sets included epidemiological investigation data reported by Occupational Safety and Health Research Institute, and data collected from occupational disease surveillance reports and Korean occupational health-related scientific journals. Number of cases, incidence rate and insurance benefits for occupational musculoskeletal disorders in Korea are increasing every year. In addition, musculoskeletal disorders occurrence is shifted from large enterprises group to small-and-medium group, from manufacturing to service sector, and from production workers to office and professional workers. Although low back pain is still most common, its occurrence characteristics is gradually shifted from traumatic to cumulative while musculoskeletal disorders are somewhat seemingly moved from lumbar to upper limb body part. Musculoskeletal disorders were observed to be more diverse and prevalent in epidemiological investigations or surveillance data rather in workers' compensation claims data. Musculoskeletal disorders occurrence is related to demographic factors, occupational psychosocial factors, and ergonomic risk factors at workplace for which appropriate preventive measures needed to be made accordingly.

  • We adapted association rules of data mining in order to investigate the relation among the factors of musculoskeletal disorders and proposed the method of preventing the musculoskeletal disorders associated with multiple logistic regression in previous study. This multiple logistic regression was difficult to establish the method of preventing musculoskeletal disorders in case factors can't be managed by worker himself, i.e., age, gender, marital status. In order to solve this problem, we devised association rules of factors of musculoskeletal disorders and proposed the interactive method of preventing the musculoskeletal disorders, by applying association rules with the result of multiple logistic regression in previous study. The result of correlation analysis showed that prevention method of one part also prevents musculoskeletal disorders of other parts of body.

  • Given the characteristics of construction work, which is highly dependent on labor compared to other industries, management of labor productivity is closely related with the construction industry. Therefore, it has become more important than ever to boost productivity in construction projects. The present study used a survey of form workers to conduct correlation analysis between factors of working tools, musculoskeletal disorders, and labor productivity. In addition, using structural equation modeling and the Sobel model, the study verified the mediating effects of musculoskeletal disorders. The findings of the analysis showed that friction sawing cutters are related with waist/back musculoskeletal disorders. In the relation between working tools and labor productivity, the hammer showed a strong positive relationship with Productivity1, standing out as the tool with the highest correlation. In the relation between musculoskeletal disorders and labor, hands/wrists showed a significant correlation with Productivity 1. The test result on the mediating effects of musculoskeletal disorders derived a statistically significant value, at Z=1.215 (p<0.05), suggesting that musculoskeletal disorders have mediating effects in the relation between working tools and labor productivity. Through this study, we identified relationships among factors related to labor productivity in construction sites; the findings of this study could be used as basic data regarding factors adversely affecting labor productivity, as well as to determine how to improve labor productivity strategically.
