본 논문에서는 영지식 기술로부터 얻어진 신분인증 방식을 둔 사용자 쌍방에 그대로 적응시켜 얻은 상호 신분인증 프로토콜은 oracle session attack하에서 결코 안전하지 않음을 보인다. 그 예로서 참고문헌 (1)에 제시된 프로토콜은 신분인증 과정뿐만 아니라 키 분배 과정 역시 안전하지 않으며 또한 참고문헌 (2)의 프로토콜 역시 상호 신분인증 과정은 전혀 안전하지 않음을 보인다. 본 논문에서는 이러한 공격이 성공할 수 있었던 몇 가지 요인들을 분석하여 안전한 상호 신분인증 프로토콜을 설계하는 체계적인 방법을 제시하고 이를 바탕으로 기존의 신분인증 방식을 키 분배가 가능한 안전한 상호 신용인증 방식으로 재구성한 몇 가지 설계 예들을 제시하기로 한다.

The purpose of this study is to attempt a text network analysis for two years of 『Reference Materials for Librarian』 (2016-2017) published by the Library Operation Methodology Research Institute in North Korea. A text network analysis can measure how important a particular word by grasping the connectivity and relationship between words beyond a simple word frequency analysis, and it is also possible to interpret specific social phenomena and derive implications. Frequency, degree centrality, the betweenness centrality, community analysis of the collected words were calculated using NetMiner. As a result, the terms 'users', 'information services', 'information needs', 'information technology', 'social learning', 'computers', 'databases', 'information acquisition', 'information retrieval' and 'librarian' were appeared as important ones in understanding North Korean libraries.

The purpose of this study is to gain a better understanding of undergraduate citation behavior and to measure the contribution which an academic library makes in the academic writing of students. Citations in 80 student papers submitted in the academic paper competition was analyzed for types of items cited and the number of items in the library collection, etc. The findings indicate: 1) the level of undergraduates' citation knowledge is very low, 2) undergraduates prefer web resources (44.9%) to such academic resources as books, journal articles, theses or dissertation, and 3) undergraduates find academic resources in their academic library. Upon these findings, this study suggests that academic library staff should intervene to enhance undergraduate academic writing skills and to develope of educational material, including how to search for and cite reliable resources.

웹 자원의 휘발성에 대한 불안에도 불구하고 학술정보 유통의 거대한 통로로 웹이 부상함에 따라 웹상에 존재하는 정보자원들이 학술정보의 재생산에 활용되어 왔다. 이에 본 연구는 학술정보에 인용된 웹 자원의 현황을 살펴보고 그것의 접근성과 유용성이 어느 정도 보장되는지를 살펴보기 위해 문헌정보학 분야의 대표적인 학술지 중 하나인 한국문헌정보학회지를 대상으로, 2007년에서 2011년까지 5년간 수록된 논문에 인용된 웹 자원을 조사.분석하였다. 본 연구를 위해 수록된 논문들의 참고문헌 중 웹 자원 비율, 현시점에서의 웹 자원의 접근 가능성, 그리고 웹 자원 주소를 분석하여 도메인과 파일 각각의 비율과 종류에 대해서 조사하였다. 또한 표기된 웹 자원의 주소는 아니더라도 인용에서 사용한 정보를 통해 웹상에서 여전히 사용가능한지를 살펴보기 위해 세계 3대 검색엔진을 사용하였다.

This study was carried out on the citations within the chemistry field Ph.D. dissertations to ascertain what types of documents are the most frequently used in the research process, the most frequently consulted journals and obsolescence rate of the journals. The analysis covered 42 doctoral theses presented at 'K' university in Seoul from 2000 to 2008. The results obtained from the 3,258 citations revealed that the most frequently used documents were Academic Journal, which accounted for 91 percent of the total; 27 journals met 50 percent of the information needs; and the age of 50 percent of the citations was no older than 9 years. Finally, the results can be used as a tool for the collection management of the library. and Researcher with the chemistry field Ph.D. dissertation.

Due to the inferior condition of local library reference service, an air of indifference about users, and the increase in Internet resources, cooperative reference service in domestic libraries tend to be stagnant. The increase in Internet resources was reconsidered, aside from traditional library reference service, based on question and answer service. It shed new light on the importance of indirect service, which is focused on reliable knowledge base construction. This study analyzed cooperative reference service, which is managed by the Japanese Diet library that pursued indirect service contrary to ours. Based on that, it suggested a new takeoff possibility for Korean cooperative reference service.

This paper aims to explore the citation patterns of conference papers in 'Information Science' discipline and to analze impacts of various cited works-related factors on future citations of conference papers. Existing bibliometric studies has investigated citation patterns and the statistical relations between a variety of bibliographic factors and the future citations of literature. However, the attentions have been focused largely on journal articles, and the bibliometric studies targeting conference papers are still in an infant stage. Therefore, this study, which is based on 1,904 conference papers in 'Information Science' field, examined several citation patterns and the contributions of the factors about cited works - the number of cited works, type of cited works, citation rates and ages of cited works at the time of being cited and the rate of self-citedness - to the future citation of the citing target articles. The data source of this study including the properties of target articles and cited works and citation rates of target articles was Scopus. As the results, 53% and 29% of the cited works were conference papers and journal articles, respectively. 14% of them are non-traditional types such as web pages, technical reports, patent, etc. More than 60% of the cited works were 5 years old or less. Among several factors considered in this paper, the number of conference papers and the number of non-traditional types of works are the most contributing factors on the citation rates of target articles. The recency of the cited works is also significant contributor on the citation rates of target articles. That is, the target articles citing more conference papers and non-traditonal types of works earned more citations. The target articles citing recent works also earned more citations.

The Libraries are face to difficult of academic journal subscription for the increasing price of journal and the increasing number of journal. Bibliographic citation analysis is one of method of evaluating the use of a journal collection. This study is used bibliographic use and scatting of foreign academic journal in Library and Information Science found in doctorial dissertation of graduate students in Seoul city, for serve to complement another method of journal evaluation. Journal selection and cancellation may be done on the basis to dispersion of journal citation to usefulness of journal subscription in the library budget. But the library should not rely on one single evaluation technique, it should take advantage of combination technique.
