To investigate the work-relatedness of carpal tunnel syndrome of some workers at packing department in a rayon manufacturing company, reseracher studied the symptoms and physical sign related to carpal tunnel syndrome of the workers at packing, ysrning, and washing department. The results are as follows: 1. By the results of ergonomic study, the packing work had the considerable probability to develop the carpal tunnel syndrome. 2. The prevalences of symptoms, physical sign and case by definition were higher in woman workers than in man workers. 3. In female workers, the age-agjusted prevalence rates of symptoms were 11.6/1, 000 in workers at washing department, 111.6/1, 000 in workers at packing department, and 70.1/1, 000 in workers at yarning department. In male workers, the age- adjusted rates of symptoms were 92.1/1, 000 in workers at washing department, 210.1/1, 000 in workers at packing and delivery department, and 0.0/1, 000 in workers at yarning department. 4. In female workers, the age-adjusted prevalence rates of physical signs were 119.5/1, 000 in workers at washing department, 104.4/1, 000 in workers at packing department, and 84.5 in workers at yarning department. In male workers, the age-adjusted rates of physical signs were 65.7/1, 000 in workers at washing department, 59.0/1, 000 in workers at packing and delivery department, and 176.9/1, 000 in workers at yarning department. 5. In female workers, the age- adjusted prevelence rates of carpal tunnel cases by case definition were 123.1/1, 000 in workers at washing department, 1117.2/1, 000 in workers at packing department, and 60.2/1, 000 in workers at yarning department. In male workers, the age-adjusted of cases were 355.9/1, 000 in workers at packing and delivery department, and 0.0/1, 000 in workers at other two departments. 6. The most of female workdrs at washing departmentn had the work history at packing department. 7. We concluded the carpal tunnel syndrome of female workers at packing department were work related.

The purpose of this study was examine the health and food intakes of industrial workers who worked day and night. The questionnaire asked them about their health, stress, knowledge of nutrition, food habits, food intakes and frequency. The night-time workers had a stomachache compaired with day-time workers. Male day-time workers were more prone to stress than night-time workers in the area of job. In the areas of nutritional knowledge and food habits, there were no significant differences between day-and night-time workers for both male and female. Intakes of rice, bread, noddle, meat, fish. beans, vegetables in night-time workers were less than day-time workers. Also the male night-time workers consumed more milk and carbonated drinks than the day-time workers. The night-time workers were worse than the day-time workers and the female night-time workers were the worst. Considering the above results, the night-time workers should correct their food habits and have a well-balanced diet.

The concept of workers' participation in occupational health was introduced to Korea recently in relation to primary health care in occupational health. But there is confusion and debate about workers' participation concept. The purpose of this study was to review the concepts of workers' participation and to conduct evaluation the workers' participation status in occupational health and safety, 394 workers and 54 employers (5.6%) in north area of Kyunggi-Do, were selected and interviewed with a questionnaire by a trained interviewer from August to September 1990. In general, the concept of workers' participation is based on industrial domocratisation and Declaration of Human Rights which had been powerful ideologies in labor movement. Contrary to workers' participation, community participation is rooted in the Health Rights. So, it is necessary to consider concept of workers' participation to improve participation. The results of survey were as follows. 1. Most of companies (71.75) carried out occupational health education to workers in study area. 2. The Occupational Safety and Health Committee (OSHC) were set up in 24.1% among the study companies, and 72.7% of workers among respondents thought that OSHC was helpful to workers health. 3. The workers signed his name to personal health report in 43.1% and the rate of participation in occupational environment examination was 54.9%. 4. The workers prefer the OSHC (39.3%), owner (35.1%) and union (25.8%) as a occupation health organisation, but owners prefer OSHC (54.5%), manager (43.2%) and union (2.3%). 5. Among the factors of the general characteristics, the existence of labor union was a major determinant of workers' attitude and level of workers' participation. As we have seen, most levels of workers' participation are low in occupational health. The variable of existence of labor union among the factors was a ma determinant of workers attitude and level of workers' participation. Therefore, in order to promote workers health, it is necessary to ponder long deeply on occupational health care system under the viewpoint of workers' participation.

The purpose of this study was to examine the eating habits and nutrient intake of industrial workers who work day and night shifts. In the area of percentage of skipped meals, the day shift workers responded that they usually skipped breakfast and the night shift workers often skipped lunch and dinner. The day shift workers answered that they skipped meals because of lack of time. The night shift workers cited poor appetite as their main reason for skipping meals. The intake of calories, Vitamin $B_2$ and calcium of the industrial workers who worked day and night shift was lower than the Korean RDA. The intake of iron of the male night shift workers was lower than the Korean RDA The intake of calories, protein, calcium, iron, Vitamin $B_2$and niacin, vitamin C of the female night shift workers was lower than the Korean RDA. In the area of nutrient intake, the night shift workers both male and female got lower scales than the day shift workers. The nutrient intake of the female night shift workers was the worst. Because they cook for themselves and live alone, their nutrient intake and eating habits were bad. The night shift workers were worse than the day shift workers and the female night shift workers were the worst. Considering the above results, night shift workers should correct their poor eating habits, their nutrient intake and have a well-balanced diet.

This paper explores the impact of the external workers on employment performance in Korea, using Workplace Panel Survey (WPS). I find the use of external workers, e.g., temporary agency workers, in-subcontract workers, and contract workers, is mainly negatively related with employment performance. Especially the use of in-subcontract workers and contract workers is negatively related with the job creation rate of standard workers and the net growth rate of internal workers. The results show the existence of a substitute effect between the use of internal and external workers.

This study was undertaken to investigate whether the stress caused by day/night shifts on industrial workers can be affected through nutritional status. A sample of 573 female industrial workers, aged 17 through 23 years, from 4 different industries (2 in normal, 2 in 3 shift work pattern) were surveyed by questionaire examining their nutritional status, food intake, dietary habit, sleep complaint, performance of digestive organs, and degree of fatigue. Shift workers were surveyed during night work. The results are summarized as follows: 1. Sleep complaints and degree of fatigue in shift workers were higher than normal workers, whereas the performance of digestive organs were as lower than normal workers. These results showed that shift workers were more stressed than normal workers. 2. The workers who were surveyed were all poor in nutritional status. The intakes of calorie, protein, Ca, riboflavin, and ascorbic acid were lower than Korean Recommanded Dietary Allowences (RDA). Dietary habit of the shift workers was irregular. 3. There was a negative correlation between nutritional status and degrss of fatigue. The intakes of energy nutrients, ascorbic acid, and niain were significantly related to the degree of fatigue in which protein intake was found to be most influential. Among workers with the same level of protein intake, shift workers showed higher degree of fatigue. When the protein intake of shift workers was 100-125% of R.D.A., they showed the same degree of fatigue to the average normal workers.

This study aims to examine attitudes of Korean workers towards foreign workers and predictors of their attitudes. The data for this study come from a survey conducted among 500 Korean workers employed at the companies which also hire foreign workers in Gyeonggi and Incheon areas. The findings reveal that a little more than half of Korean workers agree to give foreign workers the same labor rights as Korean workers and to allow them to bring their family members into Korea while a little less than half of them do not agree to grant residentship or citizenship to foreign workers. Attitudes towards foreign workers tend to be favorable with increase in perception of multiculturalism, period of working experience with foreign workers and education, and with decrease in feeling of threat from foreign workers.

Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

The purpose of this study was to identify the attitudes of non-commercial foodservice dietitians toward hiring older workers who are over fifty-five years of age. Questionnaires were sent to 600 members of Korea Dietitians Association who are working in Seoul, Korea, Data from 233 usable responses were analyzed using the SAS package program. The study showed that dietitians do not have a favorable perception of hiring older workers. Dictitians responded older workers have more serious accidents than younger workers(under age 30). In addition, they think than older workers are harder to train, find it more difficult to adapt to adapt to new ways of working, and are slower in their work. On the positive side, the response did show that dietitians realize that older workers are not absent from work as frequently than younger workers and that they are more cooperate than younger workers. The data also showed that those dietitians who had more positive experience with older workers also perceive the workers in more positive way than those dietitians that have had a negative experience with older workers(p<0.001). Finally, dietitians who are working in industrial foodservice showed more positive attitudes toward older workers than the dietitians who are working in hospital and school foodservice(p<0.01).
