This study aimed to examine structural relationship among role stresses (i.e., role conflict, role ambiguity), burnout, depression, and turnover intention among non-commissioned officers. A total 299 non-commissioned officers were participated in this study. Correlation analysis through SPSS WIN 18.0 and SEM through Amos 20.0 were conducted. The results showed that role stresses were significantly positive correlated with burnout, depression, and turnover intention. In addition, it was found that burnout mediated partially between role conflict and turnover intention. It was also revealed that burnout mediated fully between role ambiguity and depression and between role ambiguity and turnover intention as well as between role conflict and depression. From above the results, the implications of this study was discussed in terms of the necessity for building strategy to decrease turnover intention and depression of non-commissioned officers. Finally, limitations and suggestions for further researches were discussed.

This study was conducted to derive the new manager model in service economy era. It was logically explained that the modern economic society is different from the existing economic society, the modern organization that is the subject of management is different from the existing organization, and the tasks required by management are different from the existing tasks. It suggested the managerial model required for new managers. According to the proposed manager's model, the tasks required of new managers and essential qualities as managers to perform the tasks were presented. It suggested the role model that managers with required qualities should play. The role of a manager who becomes one with customers, the role of a manager who controls even his irrationality, the role of a manager who combines discernment and indiscriminateness, a flexible leadership role that combines charisma and tenderness, an administrator role that embraces regulations and non-regulations, and vision and non-vision. We derived the role of a manager who manages management, and a manager role model that utilizes both competition and non-competition. The managers engage in two opposing roles and perform management activities in a spiral dialectical cycle that develops while resolving the contradictions of each role. The method of embracing the two opposing parties internally and externally and the dialectical management execution process according to the change of the space-time axis were presented by borrowing the models of The Book of Change. Future research needs an empirical analytical study on this new Model. There is a need for studies that expand this study and develop it into a practical model and verify it in an analytical way.

In the distributed-computing environment, applications or users have to share resources and communicate with each other in order to perform their jobs more efficiently. In this case, it is important to keep resources and information integrity from the unexpected use by the unauthorized user. Therefore, there is a steady increase in need for a reasonable way to authentication and access control of distributed-shared resources. In RBAC, there are role hierarchies in which a higher case role can perform permissions of a lower case role. No vise versa. Actually, however, it is necessary for a lower case role to perform a higher case role's permission, which is not allowed to a lower case role basically. In this paper, we will propose a permission delegation method, which is a permission delegation server, and a permission delegation protocols with the secret key system. As the result of a permission delegation, junior roles can perform senior role's permissions or senior role itself on the exceptional condition in a dedicated interval.

The purpose of this study is to empirically analyze the impact of role stress (role conflict, role ambiguity, and role overload) on career commitment and turnover intention in small and medium-sized hospital workers in Busan. The subjects of the study were 418 nursing and administrative workers engaged in hospitals and general hospitals in Busan. Frequency analysis, correlation analysis, and regression analysis were conducted for empirical analysis. The results of the study are as follows. First, significant differences in some research variables were identified according to gender, age, educational background, marital status, and working years. Depending on the job type, there were significant differences in all variables such as role conflict, role ambiguity, role overload, career commitment, and turnover intention. Second, role stress was found to have a significant negative effect on career commitment and a significant positive effect on turnover intention. Among the role stress, it was confirmed that the role overload had the strongest influence on career commitment and turnover intention. This study is meaningful in that it analyzed the influence of role stress, including workers in all occupations, including nursing jobs, and empirically revealed the meaning of role stress as an explanatory variable of career commitment and turnover intention.

The purpose of this study is to examine the impacts of newspaper contents producers' role stress and burnout on their job satisfaction. For this, a survey was performed, of which the subjects were selected out of a great number of journalists employed in several newspapers. Finally, a total of 229 completed questionnaires were used for statistical inspections, such as correlation analysis and multivariate regression analysis. The results of this study can be summarized as follows: First, it is demonstrated that, the more stress journalists have with respect to role ambiguity, repetitive duties, and role conflict, which are three of the four factors causing role stress, they are less likely to have job satisfaction. However, role overload, the remaining factor of role stress, is shown to have nothing to do with job satisfaction despite it actually causes job stress most. Also, it is ascertained that role ambiguity among the aforementioned four factors of job stress has the most positive effect on job satisfaction in comparison. Second, burnout is shown to have negative correlation with job satisfaction. That is, it is identified that, the more burnout such as emotional exhaustions, depersonalization, and depreciation of personal accomplishment journalists perceive, they are less likely to have job satisfaction. In addition, it is become clear that depreciation of personal accomplishment, among the factors of burnout, has the strongest impact on job satisfaction.

IT기술의 변화에 따라 금융기관의 정보보호 또한 안정성을 보장하면서도 새로운 비즈니스모델에 적합한 보안대책이 요구되고 있다. 금융 어플리케이션의 보안은 정보의 기밀성, 무결성, 가용성을 만족하는 안전하고 신뢰할 수 있는 시스템과 네트워크, 그리고 보안사고에 큰 비중을 차지하고 있는 내부 사용자에 대한 적절한 권한 부여와 접근통제가 요구되어진다. 정당한 사용자가 접근하여 발생하는 보안 문제, 즉 내부자에 의한 악의적인 행위나 오용, 실수 등에 의한 기업의 피해는 외부자에 의한 의도적인 공격보다 피해 규모가 크다. 따라서 정당한 사용자로 인증을 받았다고 할지라도 업무처리에 있어서 필요한 최소한의 권한만을 부여하는 것이 필요한 것이다. 이를 위해 금융기관에 적합한 접근통제가 필요하다. 역할기반 접근통제는 적용범위가 제한적인 강제적 접근통제와 분산된 보안관리로 중앙에서 통제가 어려운 자율적 접근통제의 단점을 보완하고, 실제 업무처리에 적합한 특성을 갖는다. 하지만 기존 역할기반 접근통제를 금융기관의 다양한 금융 어플리케이션에 적용하면 다음과 같은 문제가 발생할 수 있다. 첫째, 금융 어플리케이션에서 사용되는 역할 추출 및 관리가 어렵다. 둘째, 다양한 비즈니스모델이 원하는 직무분리가 복잡하고 어렵다. 셋째, 악의적인 내부 사용자가 역할을 변조하여 과도한 권한을 가질 수 있다. 따라서 본 논문에서는 기존의 역할기반 접근통제에 인사정보 연동을 통한 효율적인 역할 추출 및 분류방안과 역할관리, 직무분리의 세분화 그리고 역할의 안전한 관리를 위해 X.509기반의 권한관리 기반구조(PMI)를 이용한 권한관리 기술을 금융 어플리케이션 환경에 효율적으로 적용하는 방안을 제시한다.

Information technology leadership roles have undergone fundamental change over the past decade. Despite increase interest in recent years, little empirical research on Information Technology has been done. This paper suggests results from a survey in Korea on Information Technology. The survey collected data on general leadership roles such as information roles, decisional role and interpersonal role, as well as on specific Information Technology leadership roles such as planning leader, R&D manager, general manager, chief operating strategist. The role of a change leader is positively influenced by the number of years, the extent of strategic responsibility and the organization's revenue while it is negatively influenced by the number of years in the current position. R&D manager can be predicted by strategic responsibility and chief executive's IT use, Manager can be predicted by the extent of strategic responsibility. Although several significant predictors of Information Technology leadership roles were identified, the more signigicant study should continue in the future.
