The purpose of this empirical study is to investigate the factors of self-leadership depending on individual characteristics, job characteristics, and qualities of leader-member exchange. Additionally, this study aims to discover the effect of self-leadership's outcome factors on organizational citizenship behavior and innovative activities. In order to verify research model and hypothesis, questionnaires were collected from department members working at general hospitals, hospitals, and clinics in metropolitan area of Seoul, which were 85 departments and 344 respondents. Collected data were analyzed with SPSS ver. 19.0 and Amos ver. 18.0 statistical package using Structural Equation Model. The results of the analysis showed that both individual characteristics and job characteristics have significant positive effect on self-leadership. Also, self-leadership had significant positive relationship on innovative action and organizational citizenship behavior. The implications of this study are as follow. First, this study empirically explained how self-leadership is applied in healthcare organizations. Second, it verified the relationship between causal factors and outcome factors of self-leadership. Also, prior researches of self-leadership have been conducted on business companies, but this study explored self-leadership at healthcare organizations, which increased external validity. Nowadays, many people are interested in the effect of leadership in order to overcome issues coming from enlarged organizations and to improve performance. Self-leadership will contribute to maximizing voluntary efforts of human resources and performance in a rapidly changing healthcare industry.

Recently, blogging has been regarded as a promising media for information sharing and relationship building. However, it is not quite sure if the technology acceptance model could be completely adopted also in relationship-based system such as blog. Hence, the purpose of this paper is to identify the factors affecting the usage of blogs. To do so, content analysis methodology is applied to extract meaningful factors affecting the usage of blogs in the opinions of the bloggers in a Korean portal site : Naver. We investigates the causal relationship among three factors ; perceived usefulness, perceived encouragement, and actual use in blogging. Moreover, public self-consciousness, self disclosure and telepresence are also considered as the determinants. The results show that public self-consciousness and self disclosure are significant elements affecting perceived usefulness and perceived encouragement, while perceived usefulness and perceived encouragement both affecting the actual use of blogs.

The Sightseeing ITS is defined as a system that gives tourists and inhabitants the information concerned with road network conditions, parking, sightseeing spots, and travel time in the relevant area. When focusing on tourists' excursion behaviors in sightseeing areas, however, it is sometimes found that they feel much annoyed with insufficient information about the area. While they also have a variety of needs to get information and make a decision about their excursions, it becomes one of important subjects to understand the actual circumstances of their information usage and to identify the causal relationship between their excursion patterns and the obtained information. This paper aims to investigate basic issues toward development of Sightseeing ITS and to modify an analytical model of tourist's excursion behavior considering information usage at Fuji five lakes Area, which is a representative sightseeing place in Japan. The relationship was analyzed using a structural equation model: information usage at the scheduling stage has an impact on tourists' individual cognition of the sightseeing area, tourists' individual cognition affects information usage at the excursion stage, and information usage at the excursion stage affects behavior during excursions. It is found that tourists' decision making behaviors on their excursion tend to depend on the information usage. This implies essential results to construct effective and customer oriented ITS.

Purpose: The purpose of this study was to determine whether Selection, Optimization and Compensation (SOC) Strategy mediated the relationship between job stress and health promoting behaviors among nurses. Methods: A descriptive causal relationship research design was used. 245 subjects recruited from the five general hospitals, which have over 500 beds in Seoul and Kyunggi-do, participated in the study by completing a survey which included questions about SOC strategy, job stress and health promoting behaviors. t-test, ANOVA, Pearson's correlation coefficient and multiple regression were used to analyze the data. SPSS/WIN 20.0 was used for all analysis. Results: The mean job stress score was 47.89; mean SOC strategy score was .71. 'Spiritual development' was the highest reported health promoting behavior with a mean of 3.57. Job stress was significantly and negatively related to health promoting behaviors. The result showed that all the mediating paths of SOC strategy were significant. The partial mediating model showed high goodness of fit demonstrating that the model was outstanding. Conclusion: SOC strategy mediated the relationship between job stress and health promoting behaviors. Applying better SOC strategies among nurses will increase flexibility in responding to job stress and will also better perform health promoting behaviors.

Financial ratios are key indicators of an organization's financial and business conditions. Among various financial indicators, profitability, financial structure, financial activity and liquidity ratios are frequently used and analyzed. Using the structural equation modeling(SEM) technique, this study examines the structural causal relationships among key financial indicators. Data for this study are taken from complete financial statements from 142 hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting teaching hospitals. In order to improve comparability, ratio values are standardized using the Blom's normal distribution. The final model of the SEM has four latent constructs: financial activity(total asset turnover, fixed asset turnover), liquidity(current ratio, quick ratio, collection period), financial structure(total debt to equity, long-term debt to equity, fixed assets to fund balance), and profitability(return on assets, normal profit to total assets, operating margin to gross revenue, normal profit to gross revenue). While examining several model fit indices(Chi-square (df) = 178.661 (40), likelihood ratio=4.467, RMR=.11, GFI=.849, RMSEA=.157), the final SEM we employed shows a relatively good fit. After examining the path coefficient of the constructs, the financial structure of the hospital affects the hospital's profitability in a statistically significant way. A hospital which utilizes its liabilities, more specifically fixed liabilities, and makes a stable investment decision for fixed assets was found to have a higher profitability than other hospitals. Then, the standard path coefficients were examined to directly compare the influence of variables. It was found that there were no statistically significant path coefficients among constructs. When it comes to variables, however, statistically significant relationships were found. between. financial activity and. fixed. asset turnover, and between profitability and normal profit to gross revenue. These results show that the observed variables of fixed asset turnover and normal profit to gross revenue can be used as indicators representing financial activity and profitability.

One recurrent theme within the literature on 6 sigma was the study of its effect on organizational performance. Nonetheless, most research were focused on analyzing the relationships between the implementation of different elements and several types of performance. This research incorporated the effect of organizational environment as a variable for explaining the impact of 6 sigma on business results. The model was tested using regression analyses, employing a survey of employees of hotels' cuisine departments involved in 6 sigma. The causal analysis results showed that dynamism, munificence and complexity influenced the degree of implementation of the main 6 sigma principles. Similarly, the dimensions of 6 sigma had an impact on employees' work commitment. The model could be used by hotels to assess their level of 6 sigma success depending on specific environmental characteristics.

Given the 4 contexts-parents, friends, teachers and community- of adolescents, this research verified the casual relationships between each contextual support and the suicidal impulse, and the gender difference. The 4-year longitudinal data(KYPS) collected from 3,697 adolescents were used in this study. Using the Autoregressive Cross-Lagged Model, the suicidal impulse was consistently present from the 3rd grade in middle school to the 3rd grade in high school with significant stability. Gender differences were founded in the effect of parental support among the 3rd grade in middle school. Also the negative effect of friends' support on the suicidal impulse among the first grade high school students. The effects were more stronger for girls than boys. Previous supports by teachers and community had no significant effects on later suicidal impulses. These results suggest that the study of suicidal impulse needs to examine the complex support system of multiple context layers.

The purpose of this study was to find general trends in dental fear among adolescences at 15-17 years of age, differences in levels of dental fear according to relevant variables, and the degrees to which those variables influence fear of dental treatment and their causal relationships. The researcher made use of a questionnaire including tools of questionnaire survey DFS, DBS and questions regarding characteristics of adolescences, and then analyzed covariate structure modeling by using LISREL 8.12 after conducting univariate analysis by employing SPSS. Cronbach's reliability coefficients showed higher in DFS(0.957), DBS(0.916), and GFS(0.910). The more recent experience in pain in the oral cavity and the stronger pain when treating dental disease and the more frequent experience in pain when treating dental disease and also the more broken dental appointments, the higher levels of dental fear showed with statistical significance. The linear structure equation model was statistically appropriate and well fit. By the model, severity and frequency of pain during treatment, experience of breaking dental visit appointment, distrust for dentists and general fear were directly influenced on dental fear.

This study aims to examine two hypothetical models for the variables of students' environmental perspective. First hypothetical model is the mediating role of recognition and familiarity between aesthetic and negativistic perspectives. Second hypothetical model is the separate path from humanistic to dominionistic perspectives. One hundred four tenth grade students participated in this study. We used Pearson correlation, partial correlation, and path analysis to examine the fitness of hypothetical models. The findings showed that the mediating role of recognition and familiarity between aesthetic and negativistic perspectives were statistically accepted. To prevent students' bias for fancy or gross animals, the learning (for instance, recognition and familiarity) may play role in reducing the bias. Second, there were two differential paths from humanistic to dominionistic perspectives (ecologistic-naturalistic path and scientistic-utilitarian path). While ecologistic-naturalistic path does not reach dominionistic perspective, scientistic-utilitarian path does reach dominionistic perspective. To prevent students' dominionistic perspective for nature, they need to understand ecologistic-naturalistic minds for the nature.

This study modeled 4-lane highway in three-dimensional virtual reality in order to overcome difficulties of field experiment. and the research subject was placed in a driving simulator. We survey the driver's cognitive characteristics to the alignment changes in the three-dimensional virtual reality highway. Especially, maximizing the identity of driving movements and virtual scenery on the basis of the data obtained by dynamic analysis module. we minimized simulator sickness for the graphic module of driving simulator. And we carried out cognitive evaluation on the basis of adjective words extracted by dictionary and the opinion of specialist. In this study LISREL model was used to detect the causal relation between geometry and safety in cognitive side, and found that geometric change affects the safety of drivers by static and dynamic road safety model in three-dimensional combined alignments. As the result, for constructing safety road. we consider drivers' cognitive characteristics as human factors in road design, and we think that they are very important factors to improve road safety.
