Objectives: The purpose of this study is to explore the research trends of elderly oral health through a language network analysis. Methods: A total of 354 published studies with 668 keywords were collected from the Research Information Sharing Service (RISS) between 2000 and 2022. Language network analysis was performed using Textom 6.0, Ucinet 6.774, and NetDraw 2.183. Results: The most frequent keywords were 'elderly', 'oral health', 'quality of life', and 'OHIP-14'. The result of frequency-inverse document frequent keywords showed similar results to the most frequent keywords. The N-gram of keywords shows that 'elderly', 'oral health' (18 times) and 'elderly', 'depression' (7 times). As a results of the analysis of degree centrality and between centrality, 'elderly', 'oral health', and 'quality of life' were found to be high. The CONCOR analysis identified the main clusters of 'quality of life', 'oral health behavior', 'health', and 'oral function disorder'. Conclusions: The results of the current study could be available to know research trends in elderly oral health and it is necessary to improve more comprehensive study in follow-up study.

While the body of research on metadata has grown substantially, there has been a lack of systematic analysis of the field of metadata. In this study, we attempt to fill this gap by examining metadata literature spanning the past 20 years. With the combination of a text mining technique, topic modeling, and network analysis, we analyzed 2,713 scholarly papers on metadata published between 1995 and 2014 and identified main topics and trends in metadata research. As the result of topic modeling, 20 topics were discovered and, among those, the most prominent topics were reviewed in detail. In addition, the changes over time in the topic composition, in terms of both the relative topic proportions and the structure of topic networks, were traced to find past and emerging trends in research. The results show that a number of core themes in metadata research have been established over the past decades and the field has advanced, embracing and responding to the dynamic changes in information environments as well as new developments in the professional field.

본 연구의 목표는 국내 외 기록관리학 동향을 비교 분석함으로써 각 나라별 연구 주제의 동향과 그 차이를 파악하는데 있다. 기존 수행된 기록관리학 분야에서 연구동향 분석의 한계점을 극복하기 위해 그 범위를 국제적으로 확대하여 적합한 8종의 국제 학술지를 선정하고, 2000년부터 2017년까지 게재된 논문의 저자정보를 통해 국가별 기록관리학 연구논문 게재 지수를 지리적으로 시각화 하였다. 또한 시계열 기반의 내용분석을 통해 기록관리학 분야의 국제적 연구동향의 흐름을 파악하였다. 나아가 국내 연구동향과의 연계분석을 위해 국내 기록관리학 관련 학술지 6종을 선정하여 그 결과를 비교하였다. 이를 바탕으로 국내 외 기록관리학 연구동향의 거시적 흐름과 나라별 차이를 규명하고 나아가 앞으로의 학문적 방향을 예측하고 발전 방향을 제시하고자 한다.

This study conducted a content analysis of the treatises published in JKHEA(Journal of the Korean Home Economics Association). In total, 2,136 articles published in JKHEA from 1995 to the first half of 2009 were reviewed. Articles were classified by subject matters, research methods, number of researchers, presence of research fund, language and number of reference. Although it is useful to employ content analysis in reviewing academic articles on human ecology in all journal publications, the sheer size of literature available makes this task nearly impossible. As such, we have chosen JKHEA as a popular representative journal on human ecology. This study presented the empirical results of research trends and other characteristics in JKHEA. As such, the results of this study presented a snapshot analysis of research on human ecology and future trends.

본 연구는 우리나라 대표적인 정보학분야 학회지인 "정보관리학회지"에 25년 동안에 발표된 학술논문을 대상으로 동향분석을 시도하여 각 시기별 우리나라 정보학분야의 학문적 구조와 그 변화를 파악하였다. 이를 위하여 먼저 25년을 1984-1994, 1995-2002, 2003-2009로 나눈 다음, 각 기간별 "정보관리학회지"에 실린 학술논문의 주제를 분석한 후 각 논문의 주제분포, 주제영역별 논문의 증감, 주제영역별 연도 분포를 살펴보았다. 또한 논문의 표제어를 이용하여 기간별 정보학의 지적 구조를 생성하였고 세 개의 지적 구조를 비교하여 정보학 연구의 변화를 분석하였다. 그 결과 "정보관리학회지" 연구의 주요 대주제 영역은 '정보서비스', '정보조직' 그리고 '정보시스템'이며 소주제 영역은 도서관서비스, 이용자연구, 자동문헌처리, 도서관통합시스템, 시소러스/온톨로지, 디지털도서관인 것으로 나타났다. 또한 표제어의 지적 구조를 분석한 결과, 정보학의 핵심영역은 여전히 정보검색이지만 각종 도서관이나 시스템에 활용된 정보기술 기법이나 서비스 평가에 대한 연구가 점점 늘어나고 이에 대한 주제영역이 확장되고 있음을 알 수 있었다.

This paper proposes an approach for visualizing research trends using theme maps and extra information. The proposed algorithm includes the following steps. First, text mining is used to construct a vector space of keywords. Second, correspondence analysis is employed to reduce high-dimensionality and to express relationships between documents and keywords. Third, kernel density estimation is applied in order to generate three-dimensional data that can show the concentration of the set of documents. Fourth, a cartographical concept is adapted for visualizing research trends. Finally, relative vitalization information is provided for more accurate research trend analysis. The algorithm of the proposed approach is tested using papers about Traditional Korean Medicine.
