This study was designed to investigate the relationship between the stages of exercise behavior change and physical self-concept and self-efficacy of security employees in hotel casinos. The sampling was drawn from employees at 8 casinos which had more than 30 employees. Participants were selected by convenience sampling method and they completed questionnaires about Physical Self-Concept and Self- Efficacy by self-administration method under supervision of trained researchers SPSS 16.0 (Statistical Package for the Social Science) was used for data analysis in the present study. Reliability and validity were examined for the present study. The principle component factor analysis and varimax rotation were used for the present study. Eigen value 1.0 was the criterion for selecting factors. Chi-square (X) 2 test was utilized for measuring the difference in gender and types of job duties at the stages of exercise behavior change. One-way ANOVA was employed to examine the relationship between the stages of exercise behavior change as an independent variable and physical self-concept and self-efficacy as dependent variables. The Scheffe method was used to determine mean differences of groups as a follow-up test. Multiple regression analysis was utilized to test the difference of physical self-concept as dependent variable and self-efficacy as independent variable. To verify hypothesis for the study, a statistical significance level of $\alpha$=.05 was used. The results were as follow: first, there were differences found for gender and types of job responsibilities in the stages of exercise behavior change. Secondly, as security employees progressed through the stages of exercise behavior change, their physical self-concept and self-efficacy improved. Finally, physical activity and body fat had significant main effects on self-efficacy.

This study is for the pursuit of the basic application of the efficient conversion factor in the fee contract. This aims to investigate the effects of DEA efficiency index and conversion factors to identify and group the 60 hospitals with intern and residents education. To achieve the aims, AHP was used to select the inuput and output variables for DEA. It was found that the more inefficient in the technical and scale side, the higher the conversion factors were. Conversion factor and DEA efficiency index can be used very effectively to group and discriminant hospitals into a specialized general hospital and a general hospital. Even if the variables used to calculate DEA efficiency are applied to discriminant analysis, The conversion factor and DEA efficiency index have a significant power to make a function modeling. So, if we can make a more conclusive proof based on the large number samples, We can imagine to introduce a efficiency concept in the insurance fee contracts about a conversion factor in Korea Health Insurance System.

The purpose of this study was to explore organizational justice (distributive, procedural, and interactional justice) as the antecedent of and career satisfaction by conducting an integrative literature review. In addition, this study aimed to identify organizational support for career development (i.e., organizational sponsorship) as the potential mediating variable between organizational justice and career satisfaction. Based on an integrative literature review of previous research, this study proposed the conceptual model on the relationship between organizational justice and career satisfaction along with organizational support for career development. According to the conceptual model, organizational justice can add to the pool of important antecedents of career satisfaction, and organizational support for career development could mediate the relationship between organizational justice and career satisfaction. This study contributed to the human resource development (HRD) field through investigating the relationship between organizational justice and career satisfaction in a career development context in the workplace. Further, this study provided additional theoretical backgrounds to conduct organizational justice related research on diverse factors, such as potential mediating variables, influencing career satisfaction.

Reinforced concrete(RC) structural walls are major lateral load-resisting structural member in building structures. Generally these RC structural walls are coupled with each other by the coupling beams and slabs, and therefore they behave as RC coupled structural wall system. In the design of these coupled structural wall systems, member forces are calculated using elastic structural analysis. These elastic analysis methodologies for the design of coupled structural wall system was not reasonable because it can not consider their ultimate behavior and assure economic feasibility. Performance based design and moment redistribution method to solve these problems is regarded as a reasonable alternative design method for RC coupled structural wall system. However, it is not verified under various design parameters. In this study, nonlinear analysis of RC coupled structural wall system was performed according to various design parameters such as reinforcement ratio, ultimate concrete strain and wall height. Based on analysis results, design considerations for coupled RC structural wall system was proposed.

The purposes of this research was to examine the relationship between two forms of satisfaction, commitment and turnover intentions at organization, job. Also consistent with the Meyer et al(1993) notion of the three-component model of organizational commitment. Although researchers have examined organizational commitment in relation to a wide range of variables, there has been no discriminant validity of commitment at occupation and job. The purpose of the present article, are to compare the relation between satisfaction forms, commitment forms and turn intentions forms. Confirmatory factor analysis supported the proposed distinction between the three forms of commitment and two turnover intentions forms at the measurement level in the distribution industry(N=156). Results using structural equation analysis with AMOS18 showed that job satisfaction had an positive impact on job commitment forms. Organizational satisfaction positive impact on two turnover intentions forms. However it revealed that no significant relation between organizational satisfaction and job commitment, job commitment and job turnover intentions.

This study is purported for suggesting a new clustering algorithm that enables incremental categorization of numerous documents. The suggested algorithm adopts the natures of the spherical k-means algorithm, which clusters a mass amount of high-dimensional documents, and the fuzzy ART(adaptive resonance theory) neural network, which performs clustering incrementally. In short, the suggested algorithm is a combination of the spherical k-means vector space model and concept vector and fuzzy ART vigilance parameter. The new algorithm not only supports incremental clustering and automatically sets the appropriate number of clusters, but also solves the current problems of overfitting caused by outlier and noise. Additionally, concerning the objective function value, which measures the cluster's coherence that is used to evaluate the quality of produced clusters, tests on the CLASSIC3 data set showed that the newly suggested algorithm works better than the spherical k-means by 8.04% in average.

토폴로지 설계는 미리 형상이 결정되지 않은 새로운 개념의 제품을 설계하고자 할 때나 설계 경험이 풍부하지 못한 경우, 그 개념적 형상을 결정하는 데 매우 유용하다. 실제로 이러한 토폴 로지 설계의 결과를 최근 급속 시제품 제작기(rapid prototyping machine)와 함께 사용하게 되면 처음 개념설계에서 최초시제품의 형상을 예측하고 제작하는 데 많은 시간을 절약할 것으로 판 단된다. 그러나 토폴로지 최적화에 따른 구조물은 구조물의 한계 질량내에서 평균 강성이 가장 큰 구조물일 뿐, 국부적인 응력한계에 대한 최적화는 아니다. 따라서 최종적인 최적화 형상을 얻기 위해서는, 먼저 한계질량을 갖는 최적 토폴로지 구조물의 모델을 구하고, 이 모델에 대하여 설계변수에 따른 민감도 해석을 수행하여 최대응력의 한계값을 갖는 구조를 구하면 된다. 그림 10은 이러한 토폴로지 최적화와 민감도 해석을 통한 최적화를 수행하는 복합 최적설계 과정에 흐름도이다. 설계민감도 해석은 본 연구의 범위에 포함되지 않아서 여기서는 제외하였지만, 이에 관한 일반 상업화된 소프트웨어들이 많이 나와 있으므로 이를 참조하면 된다.
