The research question in this study was to see whether there were similarities and differences in HR practices of IT-based companies in Korea. Interviews with 12 HR executives and a survey of 51 IT-based companies showed that there were IT industry-specific HR practices, but no group differences except one. The only one difference between two groups (small- and medium-sized firms versus multinational corporations) indicated that the latter was better positioned in various HR practices. Four HR themes emerged from analyses of interviews and a survey data: business environment, workforce management, HR practices, and HR for competitive advantage. The fact that none from large companies was found to have female HR executive calls for an in-depth study of what is occurring and what could be done to better the workplace in terms of diversity. A large-scale study using diverse methods in the future will produce more meaningful findings on HR practices in IT-based firms in Korea.

Occupational lung diseases (OLD) are a group of preventable conditions caused by noxious inhalation exposure in the workplace. Workers in various industries are at a higher risk of developing OLD. Despite regulations contributing to a decreased incidence, OLD remain among the most frequently diagnosed work-related conditions, contributing to significant morbidity and mortality. A multidisciplinary discussion (MDD) is necessary for a timely diagnosis. Imaging, particularly computed tomography, plays a central role in diagnosing OLD and excluding other inhalational lung diseases. OLD can be broadly classified into fibrotic and non-fibrotic forms. Imaging reflects variable degrees of inflammation and fibrosis involving the airways, parenchyma, and pleura. Common manifestations include classical pneumoconioses, chronic granulomatous diseases (CGD), and small and large airway diseases. Imaging is influenced by the type of inciting exposure. The findings of airway disease may be subtle or solely uncovered upon expiration. High-resolution chest CT, including expiratory-phase imaging, should be performed in all patients with suspected OLD. Radiologists should familiarize themselves with these imaging features to improve diagnostic accuracy.

Particulate filtering facepiece respirators (PFFR) is one of the most widely used items of personal protective equipments, and a tight fit of the respirators on the wearers is critical for the protection effectiveness. In order to effectively protect the workers through the respirators, it is important to find and evaluate the ways that can be readily applicable at the workplace to improve the fit of the respirators. This study was designed to evaluate effects of mask style (cup or foldable type) and donning training on fit factors (FF) of the respirators, since these are available at various workplace, especially at small business workplace. A total of 40 study subjects, comprised of 30~50s aged male and female workers in metalworking industries, were enrolled in this study. The FF were quantitatively measured before and after training related to the proper donning and use of cup or foldable-type respirators. The pass/fail criterion of FF was set at 100. After the donning training for the cup-type mask, subjects who passed the fit test were increased from 10 to 33. Moreover, the geometric mean (GM) of FF was increased by 340% in subjects who failed the test. In addition, the training effects for the cup-type mask were significant in female and 50s aged subjects. On the other hand, although the GM of FF for the foldable-type mask was also increased after the donning training, the GM of FF for the foldable-type mask and it's increase rate were smaller as compared to the cup-type mask. Furthermore, the differences of the increase rates of the GM of FF in sex and aged of the subjects were not significantly for the foldable-type mask. The multi-distribution of leak points for the foldable-type mask may be one of causes for the less effect of training on the fit of the foldable-type mask. These results imply that the raining on the donning and use of PFFR can enhance the protection effectiveness of cup or foldable-type mask, and that the training effects for the foldable-type mask is less significant than that for the cup-type mask. Therefore, It is recommended that the donning training and fit tests should be conducted before the use of the PFFR, and that efficient tranining programs for the foldable-type mask are required.

In this study, biomonitoring methods were developed to measure BTEXs exposure level in the air, metabolites of benzene and toluene in human urine, individual susceptibility markers in human blood for evaluation of the health effects about environmental pollution. We have also performed a small-scaled molecular epidemiology study on residents in Chuncheon and workers in workplace for these method applications. The workers in workplace were surveyed as study areas, and the residents in Chuncheon which is in the suburban area were surveyed as comparative areas in this study. Actually, 31 workers in as target group and 33 residences in as control group this epidemiological study. The results obtained from this study were as follows: 1. Benzene is a well-known carcinogen, it's median concentrations were 0.00024∼0.02057ppm at suburban area and 0.002∼00.654ppm at work place, These benzene concentrations were not exceed the OSHA(Occupational Safety and Health Administration) threshold benzene level of 1ppm in the states. 2. Metabolites product of benzene(t,t-Muconic Acid) and toluene(Hippuric Acid) were not significant both in suburban and workplace area. The median concentration of t,t-MA and HA were 0.0122, 1.44277g/g creatinine, respectively. 3. In the case of individual susceptibility markers as CYPlAl, 41.8% of them has homozygous wild type(W) and who has heterozygous variant type(H) was 35.4% and 22.8% of homozygous variant type(M) genetic type. In the case of CYP2E1, 62.82% of them has homozygous wild type(D) type, 34.62% of each has heterozygous variant type (DC) and 2.56% of them has homozygous variant type (CC). Who doesn't have GSTM1 gene was 46.25% and who has GSTM1 gene was 53.75％. Who doesn't have GSTT1 gene was 40.0％ in study groups and who has GSTT1 gene was 60.0%. Who has W genetic type, which is homozygous wild type of GSTP1, was 69.18% and H genetic type, which is heterozygous variant type was 28.4%. M genetic type which is homozygous variant type was 2.4%. 4. Concentration differences of metabolites such as t,t-MA and HA in urine, which is generated by individual susceptibility marker of GSTM1, GSTT1, GSTP1 gene of Phase I and CYP1A1, CYP2E1 gene of Phase II, was examined. As a result, GSTP1 and GSTM1 indicate slight differences depend on the amount of metabolites in urine, it was not statistically significant.

The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.

In Korea, based on the Revised Law of Occupational Safety and Health a new entity of institution was set up in 1990 to provide occupational health services to SSE in which three sorts of personnel as a team have to be involved. These institutions, in charge of scores to hundreds of workplace area-wide, have been providing occupational health services without payment from employers or employees, and government reimburses through the Occupational Injury Prevention Insurance since 1993. As a service provider, a team is composed of doctors, nurses and industrial hygienists. Undergraduate and postgraduate educations for the SSE occupational health are not specified and the question on the performance of the personnel has been raised. This study was designed to analyze the facilitating factors of and barriers to the performance and its improvement of these personnel. In 1997, the survey was conducted with all 58 institutions. Structured questionnaires were mailed to 200 personnel who were providing the occupational health service for SSE. The response rate was 51.7% for doctors, 58.6% for nurses, and 60.3% for industrial hygienist, respectively. Results are as follows : 1) There is a guideline for occupational service mandated by the government. Under the guideline, the minimum frequency of visiting workplace is assured with six times of doctors, 17 times for nurse and industrial hygienist in a year. There are one doctor for every 200 factories, one nurse and one hygienist for every 100 factories. 2) All respondents have basic qualification for occupational health service. About 16.7%. of doctors are certified in industrial medicine or preventive medicine, and 64.7% of industrial hygienists had first grade certification. Totally 66.7% of personnel have been involved in occupational health for more than one year. 3) As a support system for the performance improvement, 66.3% respond that they have been provided with educational materials, advice related to industrial environment and guidance of MSDS from Korea Industrial Safety Corporation. Most respondents indicate the lack of concern of employers and employees as a main barrier to the improvement of the service. Also they are in the need of the training opportunity more focused on SSE. The Governments policy for SSE is a principal facilitating factor. Training program focused on SSE situation, manpower, technical support, etc. are areas to be improved to have a better occupational health service for SSE in Korea.

The purpose of this study was to survey working conditions of women workers. We conducted a field survey of 504 manufacturing company with many women working from May 13 to June 29, 2002. We focused on only 3 categories of metal, textile and electronics industry. The result were as follows : 1. Subjects were constituted metal 27.0%, textile 37.9% and electronics industry 35.1%. Size distribution was small scale(<50 workers) 38.1%, medium(50-299 workers) 50.2% and large(${\geq}300$ workers) company 11.7%. Women workers' proportion was 43.6% of total workers, 63.8% of total contractors. 2. A medical examination enforcement of contractors workers was very poor in comparison with that of employees(p<0.001). 3. A 53.8% of total companies have conducted shiftwork system and 2-crew 2-shift(12 hours shift system) ranked first, 56.1%(151 companies). 4. Only 61.3% of total companies conducted more than 90 days as legal standard of a maternity leave and only 2.6% of total companies had a day nursery. In conclusion, many strategies for women workers are needed by companies and government. For example, the raising of understanding about maternity protection, social support insurancing of woman worker and occupational health system improvement for contractors and small size companies.

Purpose: This study was conducted to provide the fadamental information to prepare better Occupational Health Program for SSI based on the evaluation of the experience of nurse who were working in the Government-funded subsidized occupational health program for SSI. Method: The focus group method was used. Data was collected using focus group interviews and analyzed in the framework of the Grounded theory method as mapped by Strauss and Corbin(1990). The subjects were 14 nurses. Result: We identified 60 concepts, 30sub-categories and 6 categories(Table 1). Categories were Various services, Difficulties in implement Services, Successful strategies, Program Evaluation, Alternative Plans and Adaptation to new field. Conclusion: Nurses evaluated the effect of this program that autonomous health management ability has not changed although the possibility for the small scale industries to start the health management arose by acknowledging the importance of the health management of the workplace. In spite of many difficulties in implement services, nurses provided various health services using successful strategies. They suggest that various programs such as a model set-up suitable for the quality of workplaces and a role model set-up of the occupational health nurse for SSI as well as various efforts for the activated this program were needed. Nurses had a hard time in unfamiliar field when they began this program and overcame this difficulties with various strategies.
