The T. B. mass survey on 4, 073 employees of Seoul Electric Co. was conducted with 35 x 35mm film, from which suspected cases were rechecked with regular size film for further study. Through interpretation of films those x-rayed with regular size films are classified by USNT A Classification. To those groups suggestive of pulmonary: T. B. cases were given sputum test and E. S. R. cxamination to determine whether active or inactive. Having been given chemotherapy to them the following conclusions were obtained: 1. 99 percent of the total number of employees had participated in the survey and this showed good result. 2 5.59 percent pulmonary T.

Thc localizations for the pulmonary T. B. lesion were mostly seen on both upper lung field and when the Iesion was unilateral the right upper field was more affected and the cavity Icsion was also found frequently on the right subclavicular region. 5. E. S. R. and severity of pulmonary T. B. seem to have some relationship and variable results were obtained each in 1 hour and 2 hour period ovcr the cases of minimal and modadvanced. 6.
