역할-기반 접근 제어 정책의 경우 조직의 보안 정책을 보다 효율적이고 일관성 있게 관리할 수 있지만 각 역할의 계층에 의하여 권한의 상속이 결정된다. 이 경우, 하위 개념의 역할은 상위 개념의 역할이 가지는 권한을 수행 하여야 하는 경우에 적절히 대처할 수 없고 하위 개념의 역할에 필요한 새로운 권한을 추가해야만 하고 추가되는 권한은 관리자의 권한 제거 작업 이전까지 하위 역할에 귀속되는 문제가 발생한다. 따라서 본 논문에서는 이러한 문제를 해결하기 위하여 역할이 가지는 권한의 일시적인 위임을 통하여 이를 해결하고자 한다. 이를 위하여 권한의 위임을 수행하기 위한 정책과 새로운 역할-권한 관계의 정의, 권한 위임을 위한 새로운 프로토콜을 제시하였다.

Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.

This study was performed to assume the Sematic role of the obligatory argument of the predicate in a Korean sentence, and to accomplish the task to attach the assumed thematic role to the real corpus. With this study, the maximum of the Sematic role was determined and the Criterion of the Sematic role was set. The maximum of the Sematic role was determined 22. This study arranged the Sematic role of case marker and attached the Sematic role to the predicate of the sentence within The standard Korean Dictionary. The program to attach the thematic role was developed(UTagger-SR). The Sematic role of case marker and Case frame dictionary was equipped in this program. By attaching the Sematic role, it was found that the most important the Sematic role in the korean sentence is the theme of the predicate and the next is the subject of the predicate.

현재의 컴퓨팅 환경에서 기업이나 조직내의 사용자들은 다른 사용자와 자원을 공유하며 상호작용을 통하여 보다 효율적으로 작업을 수행하게 된다. 이 경우 공유하는 자원이나 정보의 불법적인 사용을 막고 데이터의 무결성을 유지하기 위하여 사용자의 인증과정이 필요하며, 또한 사용자의 작업에 대한 접근 제어(Access Control)의 필요성이 더욱 중요시되고 있다. 임의적 접근 제어(DAC)는 객체의 소유자에게 모든 위임의 권한이 주어지고 강제적 접근 제어(MAC)의 경우에는 주체와 객체단위의 정책 적용이 어려운 단점이 있다. 최근에는 역할-기반접근 제어를 이용하여 조직의 보안 정책을 보다 효율적이고 일관성 있게 관리하고자 하는 시도가 있다. 하지만 역할-기반 접근 제어의 경우 각 역할의 계층에 의하여 권한의 상속이 결정되는 문제가 발생한다. 하지만, 하위 개념의 역할이 상위 개념이 가지는 역할의 권한을 수행 하여야 하는 경우가 발생하는데 기존의 역할-기반 접근 제어 모델은 상기의 문제를 해결하기 위한 방법이 존재하지 않고 역할에 새로운 권한을 추가해야만 하는 문제가 존재한다. 따라서 본 논문에서는 이러한 문제를 해결하기 위하여 역할이 가지는 권한의 일시적인 위임을 통하여 이를 해결 하고자 한다. 이를 위하여 권한의 위임을 수행하기 위한 새로운 모델과 새로운 역할-권한 관계의 정의, 권한 위임을 수행하는 위임 서버, 그리고 이를 수행하는 프로토콜을 제시한다.

Purpose: This study intends to examine the effects of a stepwise communication education program among nursing college students, focusing on scenarios and nursing case-based role playing. Methods: The study design was a one-group repeated measure ANOVA. Participants were 27 nursing students in practice. Students participated in 5-week stepwise communication education program using SBAR; including 1 week of lecture education, 4 weeks of scenarios and nursing case-based role playing. The data were collected at each level of the education process: pre-education, after 1 week of lectures, and after completion of scenarios and nursing case-based role playing. Repeated measures ANOVA was used to determine changes in SBAR technique knowledge and communication self-efficacy. Results: The stepwise communication education program using SBAR was effective in increasing SBAR technique knowledge, and communication self-efficacy. The lecture-based education was effective only in the area of SBAR technique knowledge and its subscale, attitudes towards SBAR. However, scenarios and nursing case-based role playing was broadly effective across communication self-efficacy, SBAR technique knowledge, and its subscale, knowledge of the SBAR. Conclusion: Based on this study, we propose that it is necessary to confirm the effect of long-term SBAR communication education using scenarios and nursing case-based role playing in nursing students' practice.

The case marking phenomenon in Korean is closely related to semantic entailment and should be studied as an interface between syntax and semantics. Assuming a direct mapping between syntactic realization and semantic information, this study investigates the role of the accusative marker ul/lul in Korean, and explores the semantic constraints working on the argument realization on the basis of proto-roles hypothesis. Specifically, I will study various types of case alternations in Korean and clarify the role of the accusative marker ul/lul, which manifests the distinction between direct object NPs and oblique NPs.

It is generally known that children's development of 'gender schema' and 'gender role stereotype' has a positive relationship with the notion of 'gender role preference'. This study analyzed an unusual case focusing on the role playing of two brothers'. The elder brother, Hyoung-Gyoo, always preferred to take the female role, and he had a preference for feminine names like "Cordelia" whilst engaging in role playing situations. The brothers can be said to have crossed the border into the realm of intersexual role playing. The results revealed Hyoung-Gyoo's clear discrepancy between gender-related perceptions and reality, and showed his younger sibling Je-Gyoo's high level of acceptance towards his brother's extraordinary gender role preference. The results of this study can serve as a useful reference point for detailing unusual development from early childhood regarding 'opposite-gender-role seeking' characteristics.

Purpose: The purpose of this study is to investigate effects of shift work on married nurses' role conflict and job satisfaction. Method: Study subjects consisted of married nurses employed at four general hospitals with over 500 beds located in Seoul and Kyunggi area. The data were collected from March 15th to April 7th, 2004 using the survey and the subjects were asked to reply through self-administrative method. Results: Mean value of role conflict of nurses who worked shift work was measured 3.12 out of 5, and that of nurses who did not was measured 2.98. Mean value of job satisfaction of nurses who worked shift work was measured 2.79 out of 5, and that of nurses who did not was measured 2.86. There was a significant reverse correlation between mean level of role conflict and of job satisfaction. Both groups, nurses who worked shift work and nurses who did not, showed significant reverse-correlation in two areas. In the case of nurses who worked shift work, role conflict not showed a significant correlation. Job satisfaction showed a significant correlation with the plan to work as a nurse and remuneration in the case of nurses who worked shift work. Duty of supporting family was the factor affecting role conflict and measured 4.2% in the case of nurses who worked shift work, and the plan to work as a nurse and the academic background in the case of nurses who did not work shift work. Conclusion: To reduce role conflict and to improve the degree of job satisfaction, there should be taken a measure to improve a financial compensating system for working shift work for nurses who worked shift work, and to help nurses not working shift work to design plans for their job as nurses with stability.

This study investigates the role of private participation in FTA Negotiation in case of US, Mexico and Japan. We utilize Putnam(1988)'s two stage negotiation model, Schelling Conjecture and Principal-Agent(P-A) theory to understand the role of private sector in FTA Negotiation. Those theories are useful to understand the behavior and interaction of key players such as private sector, congress and government in FTA negotiation. Putnam(1988)'s two stage negotiation model divides the FTA negotiation process into two processes: the external negotiation with foreign country and domestic negotiation with domestic interest group. Principal-Agent(P-A) theory provides the theoretical foundation of Putnam's two stage negotiation model, which is that principal's interest is not identical to the interest of Agent. We showed that the private sector and congress play an important role in FTA negotiation in United States. In case of Mexico, the private sector and government occupy the dominant position in FTA negotiation. In particular, the cooperation of industry and government has been successfully established via COECE in Mexico. In contrast to these countries, the role of private participation in trade policy is relatively low in Japan and Korea.
