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.

This study was carried out to analyze any possible changes in the heart rate variability(HRV) of white-collar workers of a manufacturing firm based in Chollabuk-do Province when they are stressed due to their daily job performance and thereby to help them seek a more effective method of the management of their health and help them form more desirable habits of living by finding out how seriously his or her stresses from his or her job performance affect their quality of life(QOL). As a process of the above-mentioned manufacturer's plan to do an Oriental health examination on its white-collar workers, each of the workers of the firm was given a copy of questionaires. The questionaires carried questions regarding each of the workers' general characteristics, clinical history, health-related lifestyle and the QOL and each of the workers was asked to provide his answers to the questions listed on the questionaire. The examination progressed to measure any possible changes in the HRV of an individual worker. Among all of the questionaires filled out and collected from the workers, a total of 423 data were used as the data of the research except those that had answers which were not appropriate for the purpose of the research. The analysis of each of the workers' health related quality of life(HRQOL) showed that the younger, the lower the standard of education is, each of the subjects was found to tend to show a relatively higher QOL if only he is healthy. With regard to the worker's habits of living, those who exercise on a regular basis and who get a good sleep were also found to have a comparatively higher QOL With reference to the HRV, young workers, those who have spouses, those with a high level of academic background, those with a short work experience were found to tend to have a relatively higher HRV. As regards each worker's habits of living, those who do exercise on a regular basis were found to have a comparatively higher index of HRV. RMSSD was found to have an impact on workers' general health, on the other hand TP was found to have an impact on workers' role of emotion. This result was based on findings through analyzing interrelation between HRV and QOL that stresses have an impact on the QOL. Taking a look at the above results, it was learned that individual worker's efforts to promote his or her health, along with establish desirable habits of living, these two qualities are important methods to improve the quality of life. In addition, control of stresses is necessary to improve the QOL, which is possible through emotional stabilization.
