We made a questionnaire about the burdening operations of construction workers in Korea. And we also movie was filmed about the patients who needed special management and workplaces that have many patients who suffer from pain. Some methods were devised to improve the situation by using various MSD analysis systems. To investigate the MSD condition of the construction workers of Korea, we made an investigation through questionnaire research at company construction fields. 1) Compared to the US, construction workers' MSD occurrence is significantly low (manufacturing workers 79.80%, construction workers 1.14%). 2) In this research, workers who needed special management was 8.22% and workers who confessed to pain was 4.67%. It is quite higher than 1.14% of 2005 governmental analysis. But workers who felt their pain were 233 (51.78%). Moreover, workers who answered their physical burdens were 'a bit hard' and 'very hard' were 208 (46.22%). We think that this is due to the avoidance of the workers against due to the repeated items of the questionnaire paper. 4) We analyze the operations whereis many workers confessed to pain. We are going to analyze concrete mending, block laying, painting, waterproof coating, reinforced concrete and masonry. We used ILI Soft Inc.'s MSDs Prevention Management System for analyze concrete mending, block laying and masonry operations. The result was AC4 (Very Harmful, prompt improvement is needed), Need prompt improvement and precise investigation, very high and back pain can occur. It means that MSD occurrence potential is high. 6) To improve this condition, the employers should pay attention to the prevention of MSD. Improvement of transportation and electrical tools, appropriate scaffold that considered the worker's individual height, efforts to make materials lighter, appropriate rest, improvement of heavy material handling and education (stretching, working motion, muscle intensity strengthen) are needed. 7) As a result, policy-making and systemic support for the prevention of MSD of construction workers are needed. Exact investigation about the construction workers' MSD and insurance benefit compensation should be considered.
