Abstract:
Pneumoconiosis is one of the most important occupational disease in Korea. In Pusan, most of pneumoconiosis is welders' pneumoconiosis developed in shipyard. With clinical (including interview with every patients) and radiological (chest radiographs) methods, author purposed to know the factors related to development of pneumoconiosis in shipyard welders and to apply the results to the concept for health care (management) of shipyard welders. The prevalence rate of welders' pneumoconiosis was calculated by the means of reading of chest radiographs of 547 shipyard welders. The prevalence rate of welders' pneumoconiosis (including suspected pneumoconiosis, category 0/1) was 7.9%. It was lower than that (8.9%) in same area studied in 1989. Prevalence rate increased as total welding duration increased and the welding work began early. It was higher in welders who did not use antidust mask. Probability of the occurance of welder's pneumoconiosis was related with the time that the welder began welding work. Sixteen cases among the 37 who were diagnosed as pneumoconiosis returned normal in the follow-up chest radiographs. There was no case aggrevated. The pertinent management for the personnels and their working environment contributed to the decrease of incidence of the welders' pneumoconiosis and the improvement of the disease. To prevent the occurance of the pneumoconiosis in shipyard welders, it seems to be necessary for the company to be supervised under the any legislation and to educate the welder to use the protective apparatus. It is suggested that considerate and continuous observation under the adequate management is preferable to the immediate conversion of the working department for the pneumoconiotic welders.
