  • 일반적으로 인간이 사용하는 몇 개의 주요단어를 이용하여, 문서의 분야나 주제어가 되는 일본어 키워드를 추출하는 점에 주목한다. 먼저, 학술논문에서 저자 자신이 부여한 키워드 중 분야 명이나 주제어가 문서 중에 출현하지 않는 경우를 분석하고, 단어의 개념정보를 기초로 복합어 생성규칙을 구축한다. 문서 의미와 상관없는 키워드의 추출을 억제하기 위해 중요도 결정법을 새롭게 제안한다. 추출된 키워드의 타당성 검사를 위해 자연.음성언어에 관한 일본어 논문 65파일의 타이틀과 초록부분을 이용하여 추출된 키워드의 타당성에 대한 실험을 한 결과 추출 정밀도는 중요도의 상위 1개를 출력한 경우 75%가 되어 제안방법의 유효성을 확인할 수 있었다.

  • 본 연구에서는 기술사업화 관련 1987년부터 2016년까지 국내 등재학술지에 발표된 198편의 논문을 선정하여 분석함으로써 관련 국내연구의 동향을 살펴보았다. 그 동안 축적된 국내 기술사업화연구의 시대별 흐름과 전체적인 경향을 살펴보고자 기술적분석(descriptive analysis)방법을 적용하여 연구영역, 연구방법, 연구주제, 연구대상에 대한 분석을 실시하였다. 연구시기별 분석을 통해 "기술이전촉진법" 제정 후 약 2년 후인 2002년부터 국내등재학술지에 기술사업화 연구논문 게재가 본격화되었고, 지난 2016년에는 2002년 대비 5배에 달하는 연구논문 증가세를 확인할 수 있었으며, 연구영역분석에서는 기술혁신 연구관련 4대 학회지(기술혁신학회지, 벤처창업연구, 기술혁신연구, 지식재산연구)의 연구논문이 전체의 40% 점유사실이 관찰되었으며, 분석대상논문들에 적용된 연구방법들을 살펴본 결과, 양적연구가 전체의 53%, 문헌연구 29%, 질적연구 11%, 혼합연구 8%의 순으로 나타났다. 연구대상별 연구동향은 기술수요기업을 대상으로 하는 연구가 전체의 33%, 정부의 정책 제도 및 시스템을 연구대상하는 연구가 29%를 점유하고 있다는 분석결과가 나왔으며, 연구주제의 동향분석과 관련해서는 '사업화 프로세스'를 주제로 연구한 논문이 전제의 28%, '기술사업화 요소'에 대한 연구가 전체의 23%를 차지함을 살표볼 수 있었다. 본 연구에서는 지난 30여년에 걸친 기술혁신정책들과 연계하여 그 동안 축적된 연구들을 분석하여 국내학계의 연구동향을 보다 넓은 시각에서 조망해보는 최초의 시도라는 점에서 우선적인 의의를 찾을 수 있으며, 기존 연구들을 체계적으로 분석하고 정리해 봄으로서, 그 결과로부터 향후 기술사업화 정책방향에 대한 시사점 제공과 향후 연구방향에 대한 실질적인 함의를 제공할 수 있는 기초자료로 활용될 수 있기를 기대해본다.

  • This study aims to analyze anti-bias education activities for young children in Korea by reviewing related research. Focusing on the themes of biases and teaching medium/methods applied in the research, it tends to enhance general understanding about anti-bias education activities for young children. For this purpose, a total of 125 research papers published from 1995- 2017 dealing with anti-bias activities/programs for young children were analyzed. The results of this study were as follows: In terms of the period of research, almost half of the studies (53 studies) were conducted from 2000- 2004. Regarding the themes of biases covered in the education activities, single bias related activities included 64.8% of the total studies reviewed, and the main themes of bias included disability and gender. In studies that included multiple bias themes, more than half investigated from three to five different bias themes, including appearance, family, disability, gender, race, and culture. The most common teaching medium/method applied in activities was children's story, accounting for 60.8% of all activities. The following was utilizing inclusive environment, which was 14.4% of the activities. Based on these findings, this study would help systematize the contents of anti-bias education and develop diverse teaching-learning approaches.

  • The study examines research themes, the relationship with other disciplines, and disciplinary organization of Information Science n order to analyze general research patterns in the field of Information Science. The methods used for this study is subject analysis of the journal articles and citation analysis. In result, it is found that most researchers in Information Science have studied on 'library-related information science'. But the study also finds the research pattern shift from library-related study to computer-related study.

  • Data journals and data papers have grown and considered an important scholarly practice in the paradigm of open science in the context of data sharing and data reuse. This study investigates a total of 713 data papers published in Scientific Data in terms of author, citation, and subject areas. The findings of the study show that the subject areas of core authors are found as the areas of Biotechnology and Physics. An average number of co-authors is 12 and the patterns of co-authorship are recognized as several closed sub-networks. In terms of citation status, the subject areas of cited publications are highly similar to the areas of data paper authors. However, the citation analysis indicates that there are considerable citations on the journals specialized on methodology. The network with authors' keywords identifies more detailed areas such as marine ecology, cancer, genome, database, and temperature. This result indicates that biology oriented-subjects are primary areas in the journal although Scientific Data is categorized in multidisciplinary science in Web of Science database.

  • The purpose of this study is to understand the trends and changes of the articles publishing the Journal of the Korean Association for Science Education(JKASE) in the past forty-four years. To this end, Latent Dirichlet Allocation(LDA) topic modeling analysis was performed on a total of 2,115 English abstracts of papers published in the JKASE from 1978 to 2021. As a result of LDA topic modeling analysis, a total of 23 topics were extracted, and each topic was presented with its related keywords and articles. Next, in order to examine how these topics have changed over time, we visualized the average weights of each topic for a 4-year cycle by using heatmaps. The topics that have risen or fallen were identified. The results of this study provide new insights into science education research in Korea in terms of revealing not only traditional research topics that have been consistently studied but also the topics that have changed in response to the development of educational philosophy or research methods, social or policy demands related to science education.

  • This study aimed at finding theological trends of Calvin Theological Journal by analyzing Library of Congress Subject Headings (LCSH). The study performed the time-series analysis and the analysis of distinctive terms by examining the main authors and the subject headings of the articles published in Calvin Theological Journal during 45 years. We also proposed a new method of dividing the analysis period with the change of authors and subject headings. In the analysis results, the 18 main authors had the three clusters and shared Calvin and the Reformed Theology, the Bible. The reformed characteristics were shown in the first and second period, but the reformed theology was at the margins. The frequency of Calvin became small in the third period, the frequency of the reformed theology became bigger than before, but it was at the perimeters. Literary criticism was clustered independently. There were lots of the terms of the reformed theology in the analysis of the distinctive terms in all three periods and especially in the 2-1 period science and religion were included as the distinctive terms. Therefore, the theological tendency of the Calvin Theological Journal seemed the reformed theology and Old Testament.

  • In order to satisfy the high expectations of consumers for a variety of consumer's desired subject area, information could be provided in the form of a map according to the analysis information. With the name change in 2015, LX would intend to play a role in building the information infrastructure that can be supported government policy as an intermediary between the government and private sector. Therefore, in this study, we would like to propose a plan that provide personalized information to the consumer. Through compositing a variety of time-series data(inner or outer of LX) based on public information, and analyzing spatially and temporally the rapidly changing land status. For these purpose, prior research and domestic or abroad thematic map service about thematic map making were reviewed. And the reason why the LX makes information map was presented. Also, themes of 3 field were selected, and depending on the data processing or analysis level and theme were subdivided, and then production and expression method were proposed.
