This study aims to analyze and compare centrality and brokerage measures of journal citation network focusing on textmining research. The analytic sample was 193 academic articles collected from 136 KCI journals published in 2018. The journal citation network was constructed based on citation relations. The characteristics, centralities, and brokerages of network was analyzed. The journal citation network consisted 136 nodes and 413 links with directed and weight. According to the five types of centrality(out-degree, in-degree, out-closeness, in-closeness, betweenness), journals of social sciences, engineering, and interdisciplinary research showed higher centrality. Social sciences, engineering and interdisciplinary research journals also showed higher brokerages as a result of brokerage analysis which identify five types of brokerage roles(coordinator, gatekeeper, representative, consultant, liaison). The centralities and brokerages of journals are positively correlated. This study suggested how to construct journal citation network from the articles focusing on certain topics. This was meaningful study in terms of conducting brokerage analysis and comparing it with centrality in the journal citation network.

$\underline{Purpose}$: To analyze the recent citation trend and to find a way to improve impact factor (IF) of the Journal of Korean Therapeutic Radiology and Oncology (JKSTRO) by analysis of Korean Medical Citation Index (KoMCI) citation data of JKSTRO and comparison with that of mean citation data of all journals enlisted on KoMCI (KoMCI journals) during 2000-2005. $\underline{Materials\;and\;Methods}$: All citation data of entire journals enlisted on KoMCI and JKSTRO from 2000 to 2005 were obtained from KoMCI. The trend of total and annual number of published articles and reference citations, total citations and self-citations per paper, IF and impact factor excluding self-citations (ZIF) were described and compared on both KoMCI journals and JKSTRO. $\underline{Results}$: Annual number of published articles was decreased for 6 years on both KoMCI journals and JKSTRO (32% and 38% reduction rate). The number of Korean journal references per article is 1.6 papers on JKSTRO comparing to 2.0 papers on KoMCI journals. The percentage of Korean references/total references increased from 5.0% in 2000 to 7.7% in 2005 on JKSTRO and from 8.5% in 2000 to 10.1% on KoMCI journals. The number of total citations received/paper on JKSTRO (average 1.333) is smaller than that of KoMCI journals (average 1.694), there was an increased rate of 67% in 2005 comparing to 2000. The percentage of self-citations/total citations (average 72%) on JKSTRO is slightly higher than that of KoMCI journals (average 61%). IF of JKSTRO was gradually improved and 0.144, 0.125, 0.088, 0.107, 0.187, and 0.203 in 2000-2005 respectively. However, ZIF of JKSTRO is steadily decreased from 0.038 in 2000 to 0.013 in 2005 except 0.044 in 2004. $\underline{Conclusion}$: IF of JKSTRO was slightly improved but had some innate problem of smaller number of citations received. To make JKSTRO as a highly cited journal, the awareness of academic status of JKSTRO and active participation of every member of JKSTRO including encouraging self-citations of papers published recent 2 years and submission of English written papers, and active academic cooperation with related academic societies.

As topics of researchers become diverse horizontally or vertically, academic libraries have difficulties to identify the dynamic change of researchers' needs for academic publications. This research aims to illustrate the topic areas of researchers in a department of university by analyzing bibliographies of their publications. First, researchers' publications were used to discover the topic areas where the researchers had published. Second, the cited publications in those papers were analysed to identify the expanded topic areas of these researchers. Finally, highly cited journals were analyzed by network analysis method. The major finding is that the importance of topic areas by the number of journals was not necessarily proportional to that by the number of papers. Researchers have a tendency to use many papers in a small number of journals in a certain topic area. Furthermore, the importance of topic areas discovered by researchers' publications was not the same as that discovered by researchers' citations.

In the library domain, the metadata concerning the journal and the articles published in the respective journal are the important attributes that can be used to search academic related information. In order to conduct this study, the American JATS standard and the XML DTDs of journal articles commonly used by well-known publishers were used. By comparing JATS standard to XML DTDs used by Elsevier and Springer, we were able to extract a total of 50 metadata elements(10 about the journals, 7 about the issues, 22 about the articles, and 11 about the authors). Additionally, we identified a total of 7 mandatory elements, 9 applicable mandatory elements, and 34 optional metadata elements. The implication of this study is that we selected metadata elements using XML DTDs that are used in the real world.

As a major factor for efficient management and retrieval of the articles in databases, keywords are classified into uncontrolled keywords and controlled keywords. Most of Korean scholarly databases fail to provide controlled vocabularies to indexing research articles which help users to retrieve relevant papers exhaustively. In this paper, we carried out automatic descriptor assignment experiments to Korean articles using automatic classifiers learned with descriptors in international database. The results of the experiments show that the classifier learning with descriptors in international database can potentially offer controlled vocabularies to Korean scholarly articles having English s. Also, we sought to improve the performance of automatic descriptor assignment using various classifiers and combination of them.

In the many countries including United States, numerous librarians participate as research project members and publish papers in related/non-LIS journals. In recent years, the quantity of papers published by librarians in LIS journals and the non-LIS journals is similar. This study analyzed whether librarians join the research team in various academic fields in South Korea, carry out the research together, and publish the papers in co-authorship. This study collected and analyzed 319 articles of the authors affiliated with libraries published in the last 10 years from the Korea Citation Index. As a result, there were not many articles published by the authors in the non-LIS journal. Nonetheless, specific examples of librarians collaborating closely with other disciplinary research teams were observed; Medicine, Architecture, Materials Engineering, etc. Librarians' contribution in research projects in South Korea is expected to increase in the future. Therefore, it is desirable to prepare for this such as opening courses on research projects in the library and the department of LIS which is training librarians as well.

북한의 천문학 연구현황을 살펴보기 위해 북한 학자들의 연구 논문을 조사하였다. 북한 평양천문대에서 발행하는 대표적 천문학 학술지인 천문학통보를 비롯해 과학원 통보, 기상과수문 그리고 김일성종합대학학보인 물리학, 자연과학 등의 학술지에 게재된 천문학 논문을 조사하였다. 지난 10년간 북한 학술지에 실린 논문 중 확인된 150여 편 중에서 2015-2018년 천문학통보에 게재된 47편의 논문을 분석하였다. 그 결과 태양 분야 연구가 가장 활발하게 진행되고 있으며 고천문, 인공위성, 항성 등의 연구도 꾸준히 이어지고 있음을 알 수 있다. 북한 학자들의 해외 저널 논문을 조사한 결과 2007-2020년까지 16편을 확인하였다. 평양천문대, 김일성종합대학, 국가과학원 소속의 학자들이 주로 독일이나 중국의 학자들과 공동 논문을 발표하고 있는 것으로 확인된다.

Writing high-quality papers and publishing them at prestigious academic journals would be something that every scholar strives for. This study made a network with nine academic journals in South Korea in the field of public administration and public policy and analyzed the influence of academic journals through social network analysis. Using centrality measures, such as degree centrality, beta centrality, and eigenvector centrality, this study found that Korean Public Administration Review has the highest influence on the journal network, followed by Korean Public Studies Review. However, different choice of centrality measure led to different ranking of journals in terms of their influence.

More budget is supplied to R&D in Korea, more SCI articles are published rapidly recent years. But we can't know this SCI journals included the articles by Korean are subscribed print or licensed e-journals. So This study aims at discovering the trends and phases of SCI journals and articles published by Korean using bibliographic analysis. The SCI(Science Citation Index) database DVD version was used to search for the number of times paired Korean articles from 2004 to 2006.
