역할기반 접근제어(RBAC)는 역할(Role)과 역할계층(Role hierarchy)을 통해 사용자 및 접근권한 관리를 효율적으로 수행할 수 있도록 해준다. 그러나 시스템에 수많은 사용자, 역할, 권한이 존재하는 경우 한사람의 보안 관리자가 이들을 모두 관리하는 컷은 불가능하므로 역할을 관리하는 관리역할을 두어 시스템을 효율적으로 관리할 수 있는 방법(ARBAC)이 제안되었다. ARBAC는 URA(User Role Assignment), PRA(Permission Role Assignment), RRA(Role Role Assignment)로 구성되어있다. 본 논문에서는 URA99 모델을 기반으로 사용자-역할 관리를 위하여 관리도구를 구현한다. 구현된 관리도구는 오라클의 저장 프로시저를 사용하고 자바를 기반으로 한 EJB 컴포넌트로 구현한다.

한국기혼 여교수의 가족 및 직업역할 수행과 그 효과 및 인식 본 연구는 한국의 중상 층 기혼 여교수들의 그들의 가정과 직장생활의 균형을 위한 복수역할 수행에 따른 역할 긴장도 와 역할 만족도를 조사하는 것과 한국 기혼 여교수들이 그들의 취업이 자신과 가족에게 어떤 영향을 미친다고 인식하고 있는지를 조사하는데 그 목적이 있으며, 기혼여교수들과 4년제 대학에 근무하는 남자교수들의 부인 및 한국과학 기술연구소의 연구원들의 부인인 전업주부들과 비교하여 조사하였다. 본 연구의 결과에 따르면 여교수들은 전업주부들과 비교하여 더욱 높은 역할 만족도와 긴장도를 경험하는 것으로 나타났다. 대부분의 여교수들은 자신의 취업이 자녀들과 가족들에게 긍정적인 영향을 미친다고 인식하고 있는 것으로 나타났다.

본 논문에서는 유비쿼터스 환경에서 상황 인지 역할 기반 접근 제어(CA-RBAC: Context-Aware Role-based Access Control) 모델을 제안한다. 이 모델의 설계는 이러한 응용에서 상황 기반 접근 제어 요구사항에 의해 안내된다. 이러한 요구사항은 역할에서 사용자의 멤버쉽(memership), 역할 멤버에 의한 수행을 허용하는 것과 하나의 응용 환경에서 상황 기반 서비스 통합과 관련된다. 상황 정보는 역할 멤버에 의한 수행을 허용하는 것과 관련된 정책과 역할 멤버에 의해 역동적으로 인터페이스되는 서비스의 접근과 관련된 정책인, 역할 허용 정책에서 사용되어진다. 상황 정보의 역동적인 속성은 어떤 상황 조건이 유지되는데 실패했을 때, 허용 활동과 역할 멤버쉽의 해제를 위한 모델 수준의 지원을 요구한다. 이러한 모델을 근거로 하여 본 논문에서는 상황 인지 응용을 구축하기 위한 프로그래밍 프레임워크를 표현하고 상황 기반 접근 제어 요구 사항을 명시하고 강화하는 메커니즘(mechanism)을 제공한다.

This study investigated the mate selection preferences of single female teachers by investigating the desired traits in socioeconomic, physical attractions, psychological traits and family roles of their prospected marital partner, in order to explore the current trends in homogamous marriage. A questionnaire was distributed to 295 unmarried female teachers selected by convenience sampling from the various cities. The teachers pursued homogeneity in age, educational attainment, religion, and occupation while they preferred partners with higher income level. In terms of physical assets, the attraction that the teachers felt towards the partner was the most important physical appearances. The respondents preferred partners who are masculine and an androgynous partner. The teachers held high expectations towards their future spouses in that they desired to share the roles of emotional, financial support, child care and kin keeping. A partner who shared modern sex role attitudes was preferred over someone who held traditional one. The pursuit for overall homogeneity reflects that the teachers seek for equality in their relationships with prospected marital partners by exchanging similar characteristic.

This study applies the concepts of sociotechnical theory and role theory in order to verify the effects of stress (that is, technostress) created from information and computer technology (ICT) concerning role stress and performance. We suggest diverse perspectives concerning the elements leading to technostress along with the stress-creating process of ICT among organizational members. The following four major hypotheses are proposed: (1) Technostress is positively related to role stress (e.g., conflict and overload of roles), adverse psychological outcomes, and adverse IS use related outcomes, (2) Role conflict is positively related to adverse psychological outcomes and adverse IS use related outcomes, (3) Role overload is positively related to adverse psychological outcomes and adverse IS use related outcomes, and (4) Innovation support will play as a moderator between technostress, roles tress, adverse psychological outcomes and adverse IS use related outcomes. A partial least square (PLS) with data gathered data from ICT users of organizations was used to verify the proposed hypotheses. The results supported our claims excluding the hypothesis associated to the relationship between technostress and role stress. We suggest a theoretical implication based on the verification of technostress related to the current concept of stress experienced by individuals within organizations. We also propose that a practical implication concerning the opposite effect of technostress, can be utilized as a method of reducing role stress, and suggests a diagnostic tool for assessing the degree of technostress within organizations.

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.

This study attempted to examine the characteristics of discourse on the role of schools and to explore its implications. To this end, major daily newspaper articles during the pandemic, in which discourse on the role of schools increased rapidly, were reviewed. As a result, people made the following assumptions about the role of schools. First, schools are institutions that must provide equal learning. Second, schools are institutions that must provide caring education. These findings have led to renewed essential questions about the role of schools. It is also necessary to further subdivide and discuss the role of the school raised in the discourse. The results of this study implicated that all of these roles have the potential to bring about a structure that makes each teacher lean on passion and sacrifice without distinction between the role of the school and the role of the teacher.

Recently, role-based distributed system models have been proposed to support adaptive interactions in ubiquitous application environment. A Role-based distributed model regards an application as an organization composed of roles, and separate players running role processes from the roles. When an application is running, it binds a role with a player, and the player runs dynamically assigned role processes provided by an application for supporting adaptability. However, there has not been much attention on researches about development and runtime environment for role-based distributed systems. In this paper we suggest an application framework as an environment for developing and executing role-base distributed systems. The application framework is divided into two parts: an organization framework to manage and construct an organization composed of roles necessary in the application, and a player framework to provide running environment for players. In this paper, we focus on the organization framework which supports the creation and management of organizations, directory service for players and allocation of players to roles, and message brokering between roles and players. The proposed framework makes developers to be able to develop highly adaptive distributed systems in the ubiquitous environment.

This paper empirically explores how resources and family saliency of women entrepreneurs in IT business influence their business performance. Building up on prior research and Shelton[2006], we develop hypothesis on how the strategies of resolving wok family conflict relate to determinants of performance and business performance. The central hypothesis states that role sharing would be the strategy raising up the business performance. We also posit that the role sharing strategy would be adopted by women who show high saliency in both family and work. and women who have high levels of resources. Results suggest that financial resources have significant impact on role sharing strategy and the sales. The hypothesis of positive role sharing effect on the performance is not supported, indicating that combining family role might be an obstacle to business performance of women.
