On this paper, we show the way of forming graph data structure via setting an edge between Korean actors if they appeared in the same movie. From this graph, we calculate the 'centralities' (which declared on this paper) for each actor, then examine distribution by ranking the actors of the centralities and analyze the change of the actor who is/was center on the graph by years. Finally, we suggest the way that sets the numerically Range limits on social group.

The present study was to investigate the basis of trust and distrust from the perspective of cultural psychology. We conducted a qualitative approach in terms of the reason to and psychological functions of trust and distrust. We also focused on the viewpoint of the relations between trust and distrust whether they are located on the continuum or independent dimensions. A total of 362 subjects participated in this study. The results revealed that the main reason to trust was interpersonal relationship, which indicated they have known each others well. On the other hand, the reason to distrust was based on the judgement of inconsistency between words and deeds, and other's selfish behavior. Therefore, the basis of trust and distrust was not only different but also located on the continuum. In addition, the principal psychological function of trust was a psychological safety, whereas that of distrust was a psychological anxiety.

The purpose of the national library is to collect all publications as part of the national heritage and preserve them. This study is undertaken to determine the coverage of the book collection of the National Library of Korea. Bibliographies for the year 2007 and 2008 publications are obtained from the Kyobo Book Centre and sampled 10 % systematically to be used as checklists. Coverage was determined by searching the citations against the OPAC of the National Library of Korea. Results indicate 92.25% of coverage for the books published in 2008, 78.10% coverage for the books published in 2007, and the cumulative coverage is 85.16%. The analysis shows time lag and subject fields with low coverage. Results are compared with previous studies. Reasons for the unpossessed books, such as delay of deposit and publisher characteristics, are identified. Recommendations for the coverage improvements and future research are suggested.

Evaluation of education and training is the act of measuring and observing contents related to an educational program and evaluating its quality; and thereby providing the basis for the changes in the curriculum. The National Library of Korea (NLK) has urgently needed to introduce an evaluation method that can enhance the performance and quality of its continuing education program. Therefore, this study is aimed at developing an evaluation model that can objectively and comprehensively measure the effectiveness of NLK's job training program for its librarians. To this end, the study applied Kirkpatrick's 4-Level Training Evaluation Model and conducted review of preceding researches, investigation of NLK's librarian continuing education program, along with analysis on the stakeholders' needs. Based on the results, the study suggested evaluation system to establish the directions of the evaluation system. The findings of this study are expected to be used as a practical evaluation system for NLK's librarian education program.

안전한 멀티캐스트란 동적으로 그룹 멤버가 변하는 환경에서는 현재의 그룹 멤버만 데이터를 얻을 수 있도록 멀티캐스트하는 방법을 말한다. 이를 위해 그룹 멤버간에 그룹키를 공유하며, 이 키로 암호화하여 데이터를 멀티캐스트한다. 전방향 안전성(forward secrecy)과 후방향 안전성(backward secrecy)을 제공하기 위해 멤버가 가입하고 탈퇴할 때마다 공유키를 변경해야 한다. 이 때 확장성을 위해 그룹키의 변경이 그룹 전체에 미치는 영향은 최소화되어야 한다. 지금까지의 연구는 확장성 문제를 해결하기 위해 플랫한 그룹키 공유 구조에서 계층 구조로 변화해 왔으며, 그룹의 파티션을 용이하게 하고 중앙집중 방식의 문제를 극복하기 위해 중앙 키 서버를 사용하지 않고 그룹 멤버가 생성한 값을 계산을 통하여 그룹키를 생성하는 프로토콜로 변화해 오고 있다. 하지만 지금까지 제안된 안전한 멀티캐스트 방식은 멤버의 가입은 확장성을 갖추고 있지만 멤버의 탈퇴는 그렇지 못하며, 성능 측면에서 많은 개선이 있었지만 실제 응용에 사용되기에는 아직도 연산 측면에서 적절하지 못하다. 이 때문에 이 논문에서는 실제 응용에서 안전한 멀티캐스트를 효율적으로 사용할 수 있도록 그룹키 분배를 위한 중앙 서버를 사용하지 않는 환경에서 가입과 탈퇴가 일어날 때마다 개별적으로 처리하지 않고 일괄 처리하는 여러 알고리즘을 제안하고 그 성능을 분석한다.

In order to enhance the performance of National R&D program, it is required not only the R&D funds and human resources, but also the composition of the research environment in which the researchers could fully concentrate on study. Particularly in Korea, executive burdens that arise in the course of the administration of research fund are frequently causing difficulties in concentrating on study. To remove this burden on financial management and maximize the efficiency of research funding, the government has implemented the central management system of the R&D fund. This study analyzed the moderating effects of the centralized management system of the R&D fund on the relationship between government fund and performance of the university research. Based on the analyzed result, this study concluded that the higher level of centralized management system of the R&D fund is implemented, the more influence on research outcomes grow. This study is significant to extend previous research point of view, as well as analyze the practical effect of government policies.

It has reported that a median bus-stop island on an exclusive median bus lane (EMBL) has shortened a crossing distance unit, encouraged a pedestrian's illegal crossing, and increased the number of accidents in the area. This study presents (1) the analysis of inappropriate pedestrian crossing patterns collected on exclusive median bus corridors and (2) the estimated performance of safety barriers restraining the occurrence of those. Total 19,649 pedestrian crossing data collected at the 'Sookmyung-university' median bus-stop, and the inappropriate pedestrian crossing patterns among those were grouped in terms of time and space violations. Physical safety barriers restraining illegal pedestrian crossings were considered as an alternative, and its performance in safety was quantified through microscopic simulation with conflict analyses by using surrogate safety assessment model. The findings suggest the number of conflicts reduced be 24.9 percentages compared to the one of the present condition when the physical safety barriers are placed at each of the eight ends of the EMBL pedestrian crossing.
