This study aimed at providing fundamental data to take health care plan in the aspect of Oriental medicine by evaluating the lifestyle and yangseng(養生) levels by job-type of industrial workers. General characteristics, lifestyle, and yangseng levels were investigated through self-administration questionnaire in the course of Oriental health examination for 1,190 male workers at a manufacturing company located in the Chungcheongnam-do region, and the following results were obtained. The total mean of yangseng levels was 96.73 and the evaluation mark was 3.12. The highest mark was shown in the morality yasngseng, while the lowest mark in the activity and rest yangseng. In general, the higher were age and income level, the higher were yangseng levels, and yangseng levels were found to be high in non-smokers and those who have regularly exercised. For yangseng levels by job-type, total yangseng levels were found to be high in office workers, engineer workers, and manufacturing workers in order. For detailed categories of job-type including diet yangseng, activity and rest yangseng, sleeping yangseng, seasonal yangseng, and sexual life yasngseng, yangseng levels were generally found to be high in office workers but low in manufacturing workers. In this study, difference in yangseng levels could be found by job-type of industrial workers, and lifestyle and general characteristics were found to influence yangseng levels. Therefore it is deemed that close studies on health care by job-type are required for health promotion and care of industrial workers in the future.
