This study examined two characteristics of library and information science (LIS) journals in Korea through analysis of journal coupling with common authors. This study also illustrated the trend of Korean LIS research in the recent decade. The notable change is that record management and archival studies settle in LIS domain as a major research area. We introduced two indicators, Publishing Preference Index (PPI) and Researcher Attraction Index (RAI), based on the degree of common authors among journals. Both indicators revealed notable changes in author coupling, including reversal of PPIs in some journals, which can be interpreted as proof of changes in their author groups. The RAI analysis, which measured the degree of journals' attractiveness to Korean LIS researchers and author sharing between two journals, illustrated the journals' states in a domain; this result can help find both an isolated journal and strongly bonded journals in the specific domain. Journal coupling with common authors introduced in this study proved to be an effective investigative method for illustrating journals' states in a specified domain as well as a multidisciplinary area.

This study aims to identify the cooperative relations among researchers and their network structures based on the academic papers published in the field of lifelong vocational education and training from 2000 to 2015. Authors in three representative journals, 'Journal of Lifelong Education', 'Journal of Vocational Education Research', and 'Korea Research Institute for Vocational Education & Training,' during the periods, were selected and co-authorship network analysis was applied using NetMiner 4.0 in order to find the social relation among researchers and their academic influences. The results showed that the research productivity in the field of lifelong vocational education and training forms a shape of the power function where there exist components called, 'detailed research groups.' This network structure represents characteristics of a small world. In addition, the centrality analysis suggest authors with high centrality serve as co-authors who play as a central role on the network and exchange information with other researchers, while those with high betweenness centrality serve as a channel where they transfer knowledge and information among research groups. Increasing member of co-authorship has positively contributed to the opportunity and development of cooperative research among researchers in the field of lifelong vocational education and training. However it is recommended co-authorship be formed more heterogeneously instead of a few researches centrally dominate co-authorship. Various researchers should continually conduct research for good research performances.

This study came up a library thought and the theory of cataloging through analyzing the life and writings of Seymour Lubetzky who founded the principals of cataloging in the twentieth century. This study investigated the historical social, ideological, and cultural context, using a literature survey and the methodology of historical research. Moreover, this study aimed a comprehensive research based on the results of domestic and foreign fragmentary studies, and analyzed the effects of Lubetzky's thought of cataloging. Thus, this study found Lubetzky's library and cataloging thought. The theory of cataloging that analyzes the above findings is the design of cataloging rules and a bibliographical relationship establishment. First of all, the principles of descriptive cataloging should contain the necessity, simplicity, unity, consistency, finality, and the characteristics of interrelations, and clarify the purpose of cataloging. The bibliographical relationship is built on dividing a work as an intellectual product into a book as a physical substance. Moreover, a basic entry is entered on the basis of author names for planning the concentration of works, and a corporate name and an anonym are contained in the author names for extending the concept of author.

In this paper, we suggest a design method of a metamaterial-based low-profile antenna working at 425 MHz for LEO/Cube satellites. Satellites play an important role in linking th remote nodes in a wireless communication network and covering wide areas of the globe. Especially, an increasing number of universities or individuals aspire having their own satellites and build low-budget structures such as cube satellites in LEO and the ways to reduce the sizes of their satellites. Since the antenna occupies a major portion of the satellite surface, the antenna should be miniaturized for lighter weight. The proposed metamaterial low-profile antenna, unlike the conventional patch antenna, produces such a zeroth-order resonance to create an omnidirectional radiation pattern. Also, it is connected to a UHF waveguide bandpass filter as the feeding system to examine the possible change in the situation that the antenna is combined with the system. The performances of the monopole and proposed metamaterial antennas are compared to one another.

The purpose of this study was to analyze the trends of Classification Studies in Korea from 205 research articles in five scholarly journals in Library and Information Science during the period 1986-2011. Individual article was analyzed in the aspects of specific research topics, research methodologies, data collection & analysis, and the characteristics of classification research was suggested. The amount of research paper has increased during the period and the focus of the study was on practical use and most of the papers were about new classification schedules or modification of current classification systems. Most of the papers were literature research and comparative research on classification systems by professors or graduate students. Top 9 authors in classification research were professors or lecturers and a few authors were computer science major. Therefore, various research topics, research methodologies and collaborations with other disciplines are necessary for future classification research.

The purpose of this research was to investigate the characteristics of library and information science (LIS) field in Asian countries, focusing on the case of Taiwan. In order to conduct this study, the obtained statistical data and co-authorship networks based on eight major LIS journals in Taiwan were analyzed and compared to the case of South Korea. In Taiwan like Korea, papers published by a single-author and 2 to 3 co-authors were the most common. The centrality analysis showed that leading professors in the national-level university in Taiwan have strong and distinctive ties in the network. Additional unique characteristics pertaining to collaboration in Taiwan include the existence of journals focused on practical aspects in the field of LIS and active research participation involving librarians who publish papers in these journals.

The purpose of this study is to analyse the meaning and lexical morpheme of author keywords of humanities, social sciences, and art and sport in the Korea Ciation Index (KCI) and to propose a conceptual taxonomy of the author keywords. Four top-level concept categories such as 'Substance, Abstraction, General/Common, and Object' are replaced by seven more concrete categories such as 'object, action/function, property, theory/method, format/framework, general/common, and Instance'. In the middle and lower-level concept categories, the hierarchical structure is simplified and the unbalance of term distribution is reduced by creating, subdivision, integration, elimination, and movement of the categories. The result of the test based on the STNet shows that the replaced taxonomy of concept categories has the effects of making the term allocation more balanced and properties of terms more detailed.

This research aims to analyze domestic articles related to entrepreneurship and elicit implications for future research. To this end, bibliometric analysis was conducted for the authors and titles of 1,887 articles published in the Korean Citation Index between 1997 and 2016. First, in the author analysis, Dae Yong Chung, Bong Sik Bin & Jeong Ki Park, and Sung Sik Bahn were noticeable in terms of the number of articles, the number of citation and the formation of the researchers' network. Second, in the title analysis, the characteristics of entrepreneurs and education in entrepreneurship, entrepreneurial strategies and case studies, the empirical analyses regarding entrepreneurial performance, investment in startups, and Korean IT companies were found to be the most active research fields. The results of this study can be used in selecting co-researchers and exploring research areas in the future.
