The job analysis of operating room nurses for ergonomic work posture analysis is divided into tasks. On the basis of that, a survey research and ergonomic work posture analysis are also carried out. Among operating room nurses of a cancer center in Kyonggi province who responded to the selfadministered questionnaire, nurses were observed and videorecorded to apply Rapid Entire Body Assessment(REBA) to ergonomic work posture analysis from April, 7 to May, 7. The results of analysis are as follows. The prevalence rate of musculoskeletal symptoms was 7.% and its prevalence rates by part of the body are these followings; lower back and leg/foot.9%, shoulder.%, neck.%, hand/wrist/ finger.%, arm/elbow.%. In accordance with the results of ergonomic work posture analysis, tasks that have a REBA score of have high-risk levels and require an immediate management. It shows there is a significant correlation with overall musculoskeletal symptoms and objective workloads that are estimated by REBA. In conclusion, the work conditions of operating room nurses should be improved. It is also necessary that inappropriate work postures and ergonomic work conditions are improved to prevent musculoskeletal disorders of operating room nurses.
