기존의 그리드 사용자 인가 시스템은 해당 로컬 시스템에 접근하는 사용자가 많아지게 되고, 사용자 프록시 인증서의 subject DN(Distinguished Name)과 로컬 시스템의 ID를 일대일로 매핑할 경우, 계정 관리 문제와 메모리 자원, 디스크 자원의 관리에 있어 많은 어려움을 겪게 된다. 이러한 문제를 기존의 그리드에서는 여러 subject DN이 하나의 로컬 ID를 공유하는 형태로서 해결하고자 하고 있다. 하나의 로컬 ID를 공유할 경우에 발생하는 문제는 수많은 그리드 사용자의 모든 요구사항을 적용하는데 있어 더 많은 불편함을 초래하게 된다. 이에 본 논문에서는 ID 기반이 아닌 인증서 기반의 사용자 인가 시스템을 제안하였다. 앞서 설명한 기존의 ID 매핑 방식의 인가 시스템 대신에 인증서내의 확장 필드에 사용자의 권한 등급을 추가하고, 이를 기반으로 자원에 대한 접근 제한 등급을 결정하도록 하였다.

Purpose: This case report was attempted to present the process of the end of life nursing care provided by the visiting nurse. Methods: The subject was a person who was decided the long-term care Grade 1 and received a visiting nursing service, and the service was terminated on the death, and then was selected as a case with the consent of his family. The data were collected through long-term care benefit provision records and interviews with the visiting nurse. The nursing process was presented by applying the Omaha System. Results: The subject had digestion-hydration problems and respiration problems in the physiological domain, and the problems of role change, caretaking/parenting, spirituality, and grief in the psychosocial domain were identified. Depending on the problem, the end of life nursing care was provided to the subject and family members through activities on physical symptoms/signs, dietary management, end-life care, and coping skills. Conclusion: We expect that if the visiting nurse provides anticipatory guidance on the death process, the subject will be able to prepare for death comfortably with the family at home instead of vague fear of death.

This research has investigated the perceptions of subject specialization services and the opinions of students majoring in library and information science preparing for librarianship, librarians operating in the field, and library directors on the status and ways of nurturing subject specialization for librarians, among others. To this end, based on the results of previous research and the survey questionnaire analysis, we have presented a policy to train subject librarians. First, we have proposed a plan for systematizing the current educational system within the department of library and information science. We have also suggested ways to secure subject expertise based on curriculum management, minor programs, multi-major programs, and interdisciplinary major programs based on the standard curriculum model. Second, we have presented a subject specialization educational system for field librarians, and further suggested details for the development of an educational program that can help build subject expertise and the operation of educational methods as well as the personnel in charge of implementing the educational programs. Third, we have proposed institutionalization of the qualifications of the subject librarian where the qualification requirements have been organized considering academic background, major program, library career, and career experience in the subject specialization service, further suggesting the implementation and maintenance of the system.

In this paper, cost analysis is conducted using inter-failure interval under renewable warranty subject to imperfect repair for multi-component system. One way to model the imperfect repair is to use the quasi-renewal process (Wang and Pham 1996). Two alternative quasi-renewal processes were suggested by Park and Pham (2010) using quasi-renewal process; first is an altered quasi-renewal process with random variable parameter and second is a mixed quasi-renewal process considering replacement service and repair service, simultaneously. In this study, we use the altered and mixed quasi-renewal processes and develop the warranty cost model to obtain the expected value of warranty cost and to help company make important decisions regarding the warranty policy. Numerical examples are used to demonstrate the applicability of the methodology derived in the paper.

In this paper, we consider a system working at both primary service and secondary service. A server can switch between the primary service and the secondary service or it can be assigned to secondary service as a dedicated server. A service policy is characterized by the number of servers dedicated to the secondary service and a rule for switching the remaining servers between two services. The primary service system is modelled as a Markovian queueing system and the throughput is a function of the number of servers, buffer capacity, and service policy. And the secondary service system has a service level requirement strategically determined to perform the service assigned. There is a revenue obtained from throughput and costs due to servers and buffers. We study the problem of simultaneously determining the optimal total number of servers, buffers, and service policy to maximize profit of the system subject to both an expected customer waiting time constraint of the primary service and a service level constraint of the secondary service and develop an algorithm which can be successfully applied with the small number of computations.

This study was conducted under the premise that the university library's subject specialization room is in need of major modifications in order to accommodate the needs of various majors. The subject specialization room will be able to support university library users who are inclined to use the general reading room. Therefore, the study presents spatial planning for the average university library's subject specialization room by taking into account student majors. This could be a guideline for the construction and renovation of university libraries in the future. The summary of results for this study and the conclusions are as follows: 1)Natural sciences subject specialization room should be, partially connected with the humanities/social science subject specialization room in order to provide an open-concept reference room. In the shared area connecting the two subject specialization rooms needs to be installed a staff counter and subject specialist librarian service booth for users of both subject specialization rooms. 2)For humanities/social sciences subject specialization room, partially connect with the natural sciences subject specialization room. In the connecting area between the two rooms, plan an open-concept lounge for resting and reading. 3)It is best to plan subject specialization room for art/music/physical education majors separate from the subject specification room of other majors. Structurally separate art/music/physical education major subject specialization rooms from the building or plan a separate room in an art/music/physical education building. Users of art/music/physical education majors showed a high preference for a spatially separated and specialized library structure, which proves that an art/music/physical education library need to be planed based on the specialized library structure found in law school libraries or medical school libraries. Plan the center of the room with open-concept based reading room. Use wall-sides, partitions, or shelves to create reading space separate from the shelving area.
