Worker exposures to total chromium, hexavalent chromium (VI), sulfuric acid and alkaline dust at electroplating operations and worker exposures to trichloroethylene (TCE) and methyl chloroform (MCM) at degreasing operations in eleven small industrial plants were evaluated. Appropriate local exhaust ventilation systems for both operations were designed and recommended. Results of the study are summarized as follows ; 1. Out of 134 measurements for airborne hexavalent chromium concentrations, seven were exceeding the Korean occupational health standard of $50{\mu}g/m^3$ and 45 were exceeding the NIOSH standard of $1{\mu}g/m^3$. With an exception of one measurement, concentrations of total chromium were below the Korean standard of $500{\mu}g/m^3$. 2. Worker exposures to chromium were closely related to the existing control methods at the electroplating operations. Local exhaust systems, partial coverage of the tank surface, and antifoaming agents on liquid surface were adopted as control methods. 3. With an exception of one sample, airborne concentrations of sulfuric acid and alkaline dusts were below the applicable occupational heatlth standards. 4. Three plants indicated that airborne concentrations of TCE and MCM were exceeding the Korean standards. Other plants showed lower concentrations than the standards. It should be noted that generally, the activities and workloads on the day of surveys were less than normal. 5. Since the most existing ventilation systems did not satisfy the ACGIH criteria, the ventilation systems should be improved. Some examples for designing appropriate ventilation systems are presented.

This study was conducted to evaluated the degree of job-related life style and stress of industrial workers to present fundamental materials of preventive oriental medicine. The medical examination with oriental medicine method was performed from October 14 to November 1, 2002 for the 474 industrial workers and general characters, life style and Psychosocial Well-being Index(PWI) were collected by using self-recording type questionnaire. The results were as follows; 1) All 474 of subjects were male, job type was distributed into technician, 37.8% of them, white collar worker, blue collar worker, research worker in an orderly fashion. 2) As a result of comparison between the job types in general characters, research worker group was the highest in education level, above 10 years group in employee duration and 1.5-2.99 million won group in monthly income was the largest group in all job type and the distribution was significantly different. 3) Analyzing the difference in life style according to the job type shows that significantly highest prevalence of drinking alcohol was found in blue collar workers, they drank alcohol 2-4 times a week and that workers did not smoke in all group of job type and the prevalence of exercise was significantly high in less than 1 time a week. 4) Analyzing the difference in the degree of stress according to the job type shows that blue collar worker group had the highest score in Factor 1, Factor 4 fields, technician group had the highest score in Factor 2 field and the differences were significant. Considering above results, the present study shows that there are difference in life style and stress according to the job type in industrial workers and that health management according to job type must be required to improve health condition and to prevent disease of industrial workers in the future.

Purpose: This study was conducted to understand the situation of general hospital worker's health management and health promotion. Methods: To investigate the current situation of health management in the hospital, structured questionnaires were sent to 122 occupational health providers by post. About 79% hospitals returned questionnaires. The data were analyzed using descriptive analysis, ${\chi}^2$-test by SPSS 12.0 program. Results: A quarter hospitals responded set up separated health care office for workers, 87.5% provided health educations, and 56.5% operated health promotion projects. In the contents of health promotion program embraced both health behavior practice and disease prevention, musculoskeletal disease control, infection control, smoking cessation, and exercise program were most commonly provided to the workers in order. Occupational health care provider chose the item such as budget limitation, manager's apathy, lack of employee's participation, cooperation provider, and so on as the reason of difficulty to run health promotion program in the hospital setting. Conclusion: Hospital managers need to construct infra to manage and promote worker's health. For example, establishing Industrial safety and health committee in hospital and arranging nurses who being fully responsible to worker's health. And occupational health care provider should advertise health promotion projects both managers and workers actively.

The containment building Kori Unit 1 may require sequential steps for full decommissioning. This study assumes that the containment building is to be used as an auxiliary building that handles nuclear power systems and materials during decommissioning before conversion into a greenfield. Through the derivation of guidelines and dose evaluation, it was confirmed whether the radiation workers were satisfied with the ALARA decision. The specific modeling of the external radiation exposure was performed based on the facility investigation procedures. The external radiation specific derived concentration guideline levels (DCGLs) for radiation workers in containment building were obtained using the RESRAD-BUILD code and were applied to the VISIPLAN 3D ALARA Planning Tool code to calculate the working dose and check worker safety. The derivation of site-specific and realistic DCGLs and dose evaluation via 3D modeling can contribute to the scenario development for the decommission and remediation of containment building.
