We analyzed the demographic and job features of 197 shipyard workers with work-related musculoskeletal disorders(ll/MSDs) compensated by the Industrial Accident Compensation Insurance Act, and the features of the disorders, the causes of operation and the induced behaviors. The three shipbuilding companies surveyed were located in Busan Metropolitan c i t y arid Cyungsangnam-do. The results were as follows. 1. The ages of lVMSDs patients in shipyard were 43.6 * 8.6 and the job tenure was 14.3 t 5.6. The 40’s of them was 40.1%. and the 30’s was 29.4%. Patients less than 5 year-work duration were 85.3%, and ones more than 16 year-work duration 6.6%. In occupations, welders were 32.5%, pre-welders 17.3%, and settirig engineers 6.6%. 2. The causes of WhlSDs in shipyard were works(95.4%) and outer crash or accident shock (3.6%). Based on the standard of the NlOSH induced behaviors, the causes were awkward posture (62.9%). excessive movenient(l9.3%) and repetitive rnovenient(l3.7%). 3. The compensated WhISDs by body part was the highest. 36%, in the spines, 32.0% in both the upper limbs and the spines, and 14% in the upper limbs. The number of cases of WhlSDs in body were 96 in the cervical, 79 in the lumbar and 72 in the shoulders. 4. As a result of chi-square test(f) between diagnosis and operation in body, welding and spot welding had the most diagnoses in all parts of the body among other occupations. Chi-square testw) between diagnosis and induced behavior in body showed that awkward postures recorded the highest rate and repetitive movements was the second. 5. The most hazardous occupation was thewelding(incidence rate=9.7) and the most hazardous behavior was the awkward posture.
