In this study, appropriate preventive measures are suggested as follows by analyzing industrial accident cases occurred for five years of company J and workers' survey. First, personnel management including meticulous shift work and rotation task for older workers should be made strictly in terms of safety and health management. Second, Industrial disasters occurred more in spring than in other seasons, so safety management will have to be enhanced in spring. That is, to reduce industrial disaster various occupational safety and health activities to prevent spring fatigue are needed. Third, to improve safety consciousness of workers, penalties for those who have not received safety training and for people without protective equipment are required. Also, hazard prediction training such as Tool Box Meeting shall be proceeded. Fourth, building of proactive safety culture that the workers themselves handle risk factors is urgent. Fifth, the company-wide safety and health programs including safety awards and cases presentation are needed to be planned.

The industrial use of MMMF(man-made mineral fibers), has been increasing, particularly since the banning of most asbestos products. Fibrous minerals can cause health abnormalities currently associated with occupational exposure to glass fiber. This study was conducted to evaluate health risks of glass fiber manufactory workers within the country. We examined questionaries, physical examination including auscultation, chest x-ray, pulmonary function test for 488 male workers, to go through their dermal itching symptoms and respiratory evaluation. we had the results as follows. 1. In 45% of the workers itching had been expressed at their entrance. At that time we was investigating, 18.5% had itching, and most of them complained it when they fall asleep and night. The Sequent itching site is waist and groin, upper and lower extremity in order, and it had been expressed mainly during summer and winter. 2. As the results of ventilatory functions test, 6.0% were obstructive type, 1.0% were restrictive type. So, glass fiber exposures should be controlled or elimination by protective devices in the workplace. 3. The means of FVC, $FEV_1,\;FEV_1%$ were in normal range. As the comparison of ventilatory functions by age groups, MMF was decreased significantly for the group, 50 years old and more than other groups. And the comparison by the serving periods at glass fiber producing factory, MMF was decreased for the workers had worked for $11\sim15$ years. Therefore, MMF be more sensitive index in the evaluation of ventilatory impairments caused by glass fiber workers.

The objective of this study was to investigate the nutritional and health status of women industrial workers by working fields. One hundred forty eight (105 lead and 43 office) workers were recruited from March 2005 to October 2005. Information on age, education, smoking and drinking status were collected using questionnaire and nutrient intake and diet quality of workers were assessed by average of two-day 24 hr recall method. Biochemical indexes including blood lead level (PbB), indexes for iron status, serum calcium (Ca) and serum lipid profiles were analyzed from fasting venous blood or serum. Results showed that education level of lead workers was lower than that of office workers (p<0.05), but nutrient intake levels were not significantly different by working fields. Overall nutritional status of the subject were good except for calcium, vitamin $B_2$, C and folic acid intakes. PbB of lead workers were significantly higher than that of office workers while mean corpuscular hemoglobin concentration (MCHC) and serum Ca levels were significantly lower in lead workers. MCHC was positively correlated with zinc intake (r=0.166) and serum Ca was positively correlated with vitamin C intake (r=0.179). This study confirms that lead workers need extra care to keep their health and nutritional management especially for the nutrients known to interact with lead. Tailored nutrition education for workers at specific working fields needs to be more focused for the improvement of health status of industrial workers.

This study analyzes the characteristics of occupational accidents of food delivery via motorcycle in terms of accident probability and work-days. Depending on their employment status, food-delivery workers were divided into "employed" workers (who work for restaurants) and "special-type" workers (who work for delivery platforms). Collected data include occupational accident-information during the last two years (1,468 cases for employed workers and 4,899 cases for special-type workers) and their risk information such as age, work experience, accident location, season of the accident, and weather conditions. The study finds that special-type workers had a significantly higher accident probability for the younger age group (80.8%), while employed workers had more accidents in both 20's or younger (34.9%) and 50's or older (25.4%). The number of work-days-lost was higher for special-type workers with less work experience, and it decreased with increasing work experience. Moreover, the chance for accidents was higher at night time (55%) than for day time (45%) for special-type workers as well as for employed workers. The number of work-days-lost was higher in foreign workers (180.79 days) than in Korean workers (121.44 days). Accident probability (30.7%) and work-days-lost (136.2 days) was higher in winter than in other seasons. In addition, accidents-per-day was higher on snowy days (12.7 cases per day) than rainy (8.1) and windy days (7.1). In addition, it was found that deadly accidents mainly caused injuries to face, head, and chest, while non-deadly accidents affected mainly the legs and feet. This study enables the development of better policies to prevent accidents of food delivery workers.

The objective of this study was to analyze the status of health examination, and the health care management of industries in Seoul. This will provide effective industrial health care services. 46 industries were selected as a sample, and were given self administered questionnaire developed by the academic affairs of community health nursing. The results of this study are as follows: (1) The general characteristics of industries: The greater part of the industries were manu facturing companies, 300-900 workers, in a one shift system. (2) The general characteristics of health man ager: 96% of the companies had industrial nurses and the larger industries had comprehensive health managers. 90% of the industrial nurses were full-time employees and 77% of the industrial physician were part time employees. 80% of the industrial physician were age 50 or older, while 59% of the industrial nurses were 25-29 years of age. (3) Health examination and follow up care: The proportions of the workers who took general health examination was 94%. Of those, 12% took secondary examinations. In secondary examinations, 36% were evaluated at the C-grade, 20% were evaluated at the D-grade. The proportion of the workers who were required to take special examination were 29% and of that, the proportion of the workers who actually took the examination was 88%. 85% of the workers who were recommended for follow up cares were given follow up care while working. The physical agents among the special examination were done the most frequently to detect the examination effects. (4) Health care services: Industrial nurses performed health examination most frequently and health education was done the least. There were significant differences in health care services according to the size of the industries. Companies with 300 workers or less had higher health care services than other groups. The three primary reasons of health care management and examinations of workers are: First, industrial nurses are requires to accumulate professional knowledge and experience through continuos' activities. Second, systematic and concert examination for industrial workers should be performed periodically. Third, it needs developing health education strategies that are important workers for health promotion in industries.

In the perspective of industrial health management, it is important for the employee to decrease their job stress, to improve their productivity and quality of labor. In this study, the job stress, and it's influence on PWI(Psychosocial Wellbeing Index) were investigated by the questionnaire survey of 138 industrial workers who had studied assistive technology in college. The contents of questionnaire consist of the demographic characteristics, job-related characteristics, job stress and psycho-social stress. We evaluated job stress by KOSS-SF(Korean Occupational Stress Scale-Sort Form) and psychosocial stress by PWI-SF(Psychosocial Well-being Index-Short Form). To analyze the results, we evaluated the exposure level of KOSS and PWI by demographic characteristics and job-related characteristics using significance tests. Also, we estimated the relationship among demographic characteristics, job-related characteristics, job stress and psychosocial stress, using correlation analysis. As a results, all workers were found to be in a group under the high risky stress. It showed that the scale index of female's job non-autonomy and pwi were much larger than those of male's. Therefore, to guarantee job autonomy of female workers should be more emphasized, to improve their working environment. Job type had significant relationships with many job stress category; physical environment, job demand, job instability and organization culture. Regarding pwi, the scale index of the workers who is in charge of the civil service such as contacting the disabled and the aged in person, were much larger than that of the other workers. Accordingly, the job stress management program including physical environment, job demand, job instability and organization culture, should be suggested, to decrease the stress of the workers in charge of the disabled and the elders service. The strongest predictors of pwi was organization system through maximum positive relations between organization system and pwi. Therefore, it indicates that improvement of organization system such as a fair merit rating, a manpower supply, demand plan and department cooperation is urgently needed to reduce pwi.

It is well known that Korea has got in an aged-society, and the speed of ageing is remarkably fast that has never seen before in the world. In spite of that, government officers and managers who are in charge of industrial safety seldom have interest in ageing workers, and much less ageing workers for themselves in the industrial fields. In the meanwhile the number of injured aged workers keeps going on and even increasing. Therefore this research was carried out to investigate the characteristics of aged workers on one hand, and to grasp the self-consciousness level of industrial workers on the problem of ageing. Furthermore, to develop countermeasures, opinions and hopes of middle managers in small- and medium-sized enterprises who were in charge of industrial safety and health were collected also. Though the reply rate was not so high as expected, opinions of safety and health managers were somewhat appropriate. They replied that the most urgent counterplan for ageing would be improvements of work environments followed by work assignments based upon personal aptitude. On the other hand, the self-consciousness level of aged workers was lower than middle managers, and they mainly complained of surgical disorders such as musculoskeltal disorders including lower back pains. However, they did not seem to recognize they are getting lose their physical function in maintaining body equilibrium.

If you examine the Industrial Disaster Analysis Content that occurs every year in the small and medium enterprise, industrial disaster occurs because of manager's lack of safety and worker's unprepared safety education. Therefore effective safety education systems are needed to offer adequate knowledge and technology to the workers. On this research, to give an effective education way to decrease industrial disaster we administered to the workers who are in charge of 300 workplace in Incheon area to search actual condition of industrial disaster and to disclose a link between industrial disaster and industrial safety education. We put in effect on frequency study and examined x2 using SPSSWIN 10.0. On the research, the results shows that the industrial safety education and training are in effect regularly and the satisfaction are low. But the manager's satisfactions are high through safety education. So it shows that we need to find a way to put in effect safety education to satisfy the workers.
