This study identified the impacts of organizational commitment on medical service reduction rates by lifestyles of medical institution workers with a medium of environmental factors in a medical institution, and it conducted a survey targeting 300 medical institution workers in Jeolla-do, South Korea. The results are as follows. First, there was a significant difference in an organizational commitment by sociodemographic characteristics based on age, academic career, gender, marital status, occupational description, monthly earnings, the years of employment, and the type of hospital. Second, there was a significant difference in environmental factors by sociodemographic characteristics based on marital status, the years of employment, and the type of hospital. Third, there was a significant difference in the inpatient reduction rate based on the occupational description, years of employment, and the type of hospital. In the outpatient reduction rate, a significant difference was shown based on age, marital status, occupational description, the years of employment, and the type of hospital. Fourth, when analyzing the relationship between organizational commitment, environmental factors, and the reduction rate, there was a significant positive correlation between inpatient reduction rate and outpatient reduction rate. Fifth, when analyzing the impacts on the inpatient reduction rate by deploying organizational commitment and environmental factors at the same time, it was shown that the environmental factors mediated partially in organizational commitment and inpatient reduction rate. In the case of outpatient reduction rate, it was shown that the environmental factors mediated completely in organizational commitment and outpatient reduction rate. The present study is aimed to contribute to providing the baseline data for an efficient operational plan and effective workforce management of medical institutions.

This study was carried out in order to confirm the reliability and validity of the commitment inventory developed by Meyer and Allen, and to investigate commitment level of health manager, to compare two different professionals of health manager such as industrial health nurse and industrial hygienist to find out some characteristics that have effect on commitment. This survey was done by self-administered questionnaire to 227 respondents as the trainees of Industrial Safety Training Center, KISCO from June to December 1996. Authors classified commitment into two categories ; professional commitment and organizational commitment, and these two types of commitments have three different aspects ; affective, continuance, and normative commitment based on Meyer's inventory. The results were as follows; 1. Items of whole scales of the both type of commitments have three factors that represent three aspects of commitment ; affective, continuance, and normative commitment. This means that each type of commitment was reliable to use as measurement tool of three different aspects of commitment. Classification of items by factor analysis was more consistent in professional commitment than organizational commitment. Among 16 items of organizational commitment, four items were classified into different aspects of commitment with similar factor loading. 2. Commitment level of industrial health nurse was higher than that of industrial hygienist in affective, continuance professional commitment controlled by other characteristics. These differences can be due to other characteristics of specific task and background of health managers that were not used in this study. 3. The level of affective professional commitment was statistically different in age, sex, educational level, and that of organizational commitment was statistically different in only two variables such as age, and job tenure. The level of continuance professional and organizational commitments were different in sex group, but past history of employment have effect on continuance organizational commitment. The level of normative organizational commitment was affected by only age. As the above results, the tools of measurement of commitment developed by Meyer and Allen can be useful to measure the level of commitment of health manager. Three aspects of two types of commitments were influenced by different characteristics of health manager. Authors suggested future study on the affecting variables to the commitment such as background, task of health manager and organizational characteristics.

This study aims to understand how human capital is related to the inter-regional wage gap between the capital region and the non-capital region in Korea. We focus more specifically on whether the inter-regional wage gap is due to high levels of human capital in the capital region or due to high returns to human capital in the capital region. The decomposition method based on the unconditional quantile regression was used to examine how the relationship between human capital and the inter-regional wage gap varies along the wage distribution. When first estimating earnings functions from the two regions to apply this decomposition method, we included not only conventional indicators of human capital, such as education and on-the-job training, but also occupational skills including cognitive-interactive skills, technical skills, and physical skills. As a result, other things being equal, a large part of the inter-regional wage gap was explained by the human capital variables. Although the composition effect of the human capital variables existed in all the wage quantiles, the more important factor was the wage structure effect of the human capital variables. In addition, among the various human capital variables, the wage structure effect of years of education was a key factor in explaining the inter-regional wage gap. This study is meaningful in that it shows that the relationship between human capital and the inter-regional wage gap may vary depending on the wage quantiles.

Objectives : The purpose of this study is to evaluate the appearance of having relationship between the exposure to lead and cadmium and the dental caries targeting adults in the Republic of Korea. Methods : The study was designed as a cross-sectional study, using the data of the Fourth Korea National Health and Nutrition Examination Survey. The subjects as 1,966 people, who were confirmed the appearance of dental caries among 1,991 people of having been offered the heavy-metal concentration in blood. Statistical analysis was conducted using SPSS 19.0, according to complex sampling design. Results : As a result of multi-variate analysis on factors of dental caries, in Model I without correction, the gender, age, educational level, appearance of lifelong smoking, daily toothbrushing frequency, appearance of using dental floss, and subjective oral health status were recognized as important factors. In Model II with correction of gender and age, the educational level, daily toothbrushing frequency, and subjective oral health status were recognized as statistically significant factors. In Model III with correction of all factors, the gender, age, educational level, appearance of using dental floss, and subjective oral health status were functioning as statistically significant factors. As a result of statistically analyzing relationship between the exposure to lead and cadmium and the dental caries targeting adults, it was analyzed that there is no significant correlation. However, in case of lead, the tendency of being grown the cross ratio of dental caries could be examined in model I, which didn't correct disturbance factor, model II, which corrected gender and age, and model III, which corrected all variables of disturbance factor. Conclusions : The exposure to lead and cadmium was indicated to have no relationship with adults' dental caries. However, a continuous research of relationship was considered to be necessary by using Korea National Health and Nutrition Examination Survey, which is surveyed in the future.

Pneumconiosis is a sort of pulmonary fibrosis consequent to the inhalation of the respirable dusts. Thus, the pathogenesis of silicosis have concentrated largely on the early response of alveolar macrophage and the later fibroblastic stimulation. But the role of the other cells and continuing cell injury in the pathogenesis has not been fully studied. And the chemical factors such as prostaglandin, fibroblast stimulating factor and inhibiting factor and chemotaxin are also participated in the mechanism of pulmonary fibrosis in silicosis. In order to clarify the role of alveolar cells and prostaglandin, we investigated the changes of the cellularities in bronchoalveolar lavage fluid and tissue pathology in the experimental silicosis with the time sequence. The experimental animals were divided into 3 groups; control group received only intratracheal injection of 0.5 ml saline, silica group received the intratracheal instillation of 40 mg silica with the same amount saline, and aspirin group received 450 mg/kg of aspirin after silica instillation. The results were as follows: 1) The total cells of bronchoalveolar lavage fluid in the silica group markedly increased in comparison with the control group, but there was no significant difference between the silica and aspirin groups. 2) The percentages of alveolar macrophages to the total number of cells in the silica group tended to be lower than those in the control group and also lower than those in the aspirin group at the 1st week after silica instillation. 3) The percentages of neutrophils to the total number of cells in the silica group were significantly higher than those in the control group during the entire period and also higher than those in the aspirin group at the 3rd day after silica instillation. 4) In the silica group, the percentages of lymphocytes to the total number of cells were increased 143 progressively with the time course and those were significantly higher than those in the control group from the 3rd week after silica administration. There were marked differences of lymphocyte percentages between the silica and aspirin groups at the 1st week after silica instillation. 5) The inflammatory change was observed in the rat lung at the 1st day after silica instillation. Also the silicotic nodule appeared in the silica group at the 1st week but we could not find out that nodule in the aspirin group at that time. The fibrotic changes in the rat lung tended to be increased progressively with the time course, therefore, the diffuse fibrotic pattern appeared in the whole field at the 20th week after silica instillation. 6) By the electron microscopy, there were gradual increases of phagosomes and vacuoles in the alveolar macrophage in the silica group as compared with the control group. These results suggest that the neutrophils and the lymphocytes have also participated in the pulmonary fibrosis even though the alveolar macrophage has a major role, and prostaglandin mediate the inflammation and pulmanary fibrosis in the experimental silicosis.

To continue the growth of use of 5-star hotels by Koreans, who have recently shown the consumption trends pursuing the empirical value of a consumption process, and have turned into core customers of 5-star hotels in Seoul, it is necessary to study factors of experience value pursued by Koreans. As a result, fantasy is identified as a major leading factor in usage satisfaction among experiencial values. So it is important to reflect special concepts and atmospheres for emotional values, such as other world experience, new experience, and high-quality experience. And consumer return on investment was identified as a leading factor in positively affecting usage satisfaction. So it is important to develope a proper products that can enough benefits with reasonable prices. In the relationship between usage satisfaction and continuous usage intention, gender characteristics and occupational characteristics were found to play a moderating role. Male customers, and those with professional and self-employed occupations, were found to have higher continuous usage intention than females and other occupational customers. This is a result of the fact that customers with an economical power are likely to be continuous repeat customers of 5-star hotels, so the necessity of strengthening marketing activities such as research on the development of more differentiated and specialized products, service creation and atmosphere production for excellent consumers group.

This study analyzes the major factors affecting domestic middle-aged and elderly households' strength in consumption using the first and second wave of Korea Longitudinal Study of Ageing(KLoSA). First, household income and household liquid assets which are the strength in household consumption was analyzed and as a result, among various explaining variables, aged and elderly households with the higher education level and more household members, those in self-owned residence and in a state of labor and those which are the beneficiaries of special occupational pension scheme show relatively the same high level of strength in consumption. Then, the determining factor of household consumption was assumed based on the second wave of data and as a result, those with more yearly household disposable income and household liquid assets, those living in metropolitan cities with self-owned homes, those engaged in labor practice or which are the beneficiaries of special occupational pension scheme are more likely to have a relatively bigger contributory factor in increasing household consumption. By contrast, household's consumption decrease in the case of those with higher age, those who are the beneficiaries of national pension or those who are male.
