The aim of this study was to analyze the research trends on the digital libraries in Korea. To achieve this objective, a total of 578 author-assigned English keywords were collected from the 272 major LIS journal articles published in Korea during last ten years-period, i.e., 2007-2016. The collected data were analyzed using NetMiner V.4 to discover their 'degree centrality' and 'betweenness centrality'. As the results, 'Academic Library', 'Reference Service', 'Public Library', 'E Resource', and 'E Book' showed the most frequently conducted research topics, and 'Academic Library', 'Reference Service', 'Information Behavior', and 'E Resource' were the most influencing research topics. Finally, 'Academic Library', 'Metadata', 'Information Behavior', 'E Resource', and 'Librarian' seemed the most widely intervening research topics in this research.

Currently, there are many subscriber access networks: PSTN, ADSL, Cellular Network, IMT200 and so on. To these service providers that provide above network service, it is important that they authenticate and authorize legal subscribers and account for their usage. At present, There exist the several protocols that Support AAA(Authentication, Authorization and Accounting) service : RADIUS, Diameter, TACACS+. Nowadays, RADIUS has used for AAA service widely. It has been extended to support other access network environment. So, we extend RADIUS to support environment of Mobile IPv6. Mobile IPv6 uses IPsec as a security mechanism, basically. But, IPsec is a heavy security technology for small, portable, mobile device. Especially, it is serious at IKE, the subset of IPsec. IKE is a key distribution protocol that distributes the key to the endpoints of IPsec. In t:lis paper, we extend RADIUS to support environment of Mobile IPv6 and simplify the IKE phase of IPsec by AAA system distributing the keys by using its security communication channel. Namely, we propose the key distribution method for IPsec SA establishment between mobile node and home agent. The suggested method was anticipated to be effective at low-power, low computing deyice. Finally, end users feel the faster authentication.

This study analyzed the type, subject and open level of research data in the field of library and information science field shared by Figshare, and statistically analyzed the characteristics of data with relatively high recyclability. The results of the analysis showed that datasets and papers were most common data types, and open access and research data were the most common keywords of data, and that 70% of the data were published in a form that can not be processed mechanically such as pdf. As a result of analysis of the relationship between characteristics of research data and degree of sharing, open access areas such as APC (Article Processing Charge) were found to be most common in the subject. However in data type, gray literature such as paper found to be highly utilized rather than dataset.

The purpose of this study is to analyze academic research trends of the library management in Korea. Especially, this study focused on research trend analysis according to the sub categories of library management. For this purpose, this study analyzed a total of 359 papers of library and information science from 2004 to 2013 at the four academic journals of the National Research Foundation of Korea. As a result, it was found that the sub field which showed the highest performance was 'general management' and following sub fields were 'measurement and evaluation', 'human resource management', 'building and facility', 'policy and system.' However, there has been relatively less performance in the sub fields like 'marketing', 'organization management', 'budget management'.

While numerous studies have empirically investigated user behavior in LIS research community, less research has attempted to examine such studies in methodological perspective. Reflecting this, relevant studies have suggested the need to develop methodological framework for such studies. This study conducted content analyses of user behavior studies recently published in JASIST and analyzed factors which affect the external validity of result of such researches. The findings revealed various types and cases related to the generalization of the study results. Based on these, a methodological framework for user behavior studies were suggested.

원자료는 행하여진 연구결과를 도출하기까지 발생된 기초자료로써 다듬어지지 않은 자료를 의미한다. 이러한 원자료는 이미 행하여진 연구와 유사한 연구를 진행하는 후속연구자에게 있어 시간과 노력을 절약하는 것이 가능하게 해준다. 본 연구는 인문사회분야의 원자료 제공 서비스인 한국연구재단의 기초학문자료센터에 대한 문헌연구와 해외의 유사기관에 대하여 알아보고 지속가능한 서비스를 위한 방법인 오픈아카이브에 대하여 알아보고자 하였다. 향후 기초학문자료센터의 기 구축된 자료에 대하여 실제 사용자의 만족도를 조사하고 이를 통해 콘텐트의 보완 및 메타데이터 항목의 적절성과 질에 대한 실질적인 연구가 필요하다.

Today, the state of libraries in cur country is behind the times and the consdousness of people who use l i e s falls behind, too. Meanwhile, the workout and unlimited competitions have resulted in the crisis on the state of our libraries. The crisis on the state of cur libraries has led to that of our discipline. In this paper, I study the causes of crises in our discipline and libmies. I suggest some methods to cure the illnesses.

본 연구는 정보학 분야의 저명한 연구자 T.D.Wilson의 연구주제 분야를 네트워크 분석을 이용하여 해석해보고, 그의 연구는 물론 정보학 분야의 연구주제에 관한 이해를 도모하는 데 연구의 목적이 있다. 이를 위해 그의 저작을 대상으로 서지결합분석 방법을 이용한 군집 분석을 실시하여 연구주제를 나누어 보고 대표적인 연구주제와 논문, 그리고 인용빈도와의 관계를 규명하였다. 패스파인더 네트워크와 노드엑셀을 이용한 분석 결과, 대표적인 연구주제는 정보행위연구이고 논문으로는 "Human information behavior(2000)"로 나타났다. 더불어 '정보요구'라는 핵심 연구주제 아래 정보탐색, 정보관리, 정보이용, 웹정보에 이르는 정보학 분야의 다양한 연구가 이루어졌음을 알 수 있다.

In this paper, we analyzed the research trend of Library and Information Science field in Korea using science and technology authority data which has been constructed by KISTI. The authority data is a set of data given a unique identifier to identify a unique object for the authors, affiliations and journals of domestic and international academic paper that published in Korea or written by Korean authors. We examined collaborating patterns, authors and institutional productivity through analyzing the 5 domestic LIS journals published from 1997 to 2013.

As the first step in developing the optimal co-authorship allocation method, this study investigated the co-authorship allocation standards of Korean Universities on journal publications. The study compared the standards of 27 Korean universities with Library and Information Science (LIS) departments, and analyzed author rankings generated by applying inflated, fractional, harmonic, and university standard method of co-authorship allocation to 189 Korean LIS faculty publications from 2001 to 2014. The university standards most similar to the standard co-authorship allocation method in bibliometrics(i.e. Vinkler) were those whose co-author credits summed up to 1. However, the university standards differed from Vinkler's in allocating author credits based on primary and secondary author classification instead of allocation based on author ranks. The statistical analysis of author rankings showed that the harmonic method was most similar to the university standards. However, the correlation between the university standards whose co-author credits summed up to greater than 1 and harmonic method was lower. The study results also suggested that middle-level authors are most sensitive to co-authorship allocation methods. However, even the most generous university standards of co-authorship allocation still penalizes collaborative research by reducing each co-authors credit below those of single authors. Follow-up studies will be needed to investigate the optimal method of co-authorship credit allocation.
