We have been provided with a plenty of information about IT through the conferences. However, it is hard to find enough information or the latest trends from conferences because there are too many conferences. In this situation, we analyzed the latest trends related to the field of IT by exploiting the Netminer which is one of the software for analysis of social networks and measuring the Cosine Similarity between conferences, based upon keywords which are included in the conferences. We analyzed keywords of 24 conferences related to the computer network part of the IEEE (Institute of Electrical and Electronics Engineers) in the case of foreign conferences. We also analyze keywords of the KIISE (Korean Institute of Information Scientists and Engineers) conferences in the case of domestic conferences, during 2009-2010. We identified the trends through the frequency of keywords, the change of top 10 keywords ranking and the similarity between conferences.

This study aims to find out the ESG management keywords in the logistics industry through social network analysis using news article and sustainable management reports. In recent years, global climate change and Covid-19 have spurred companies to step up their new management system called ESG management. ESG is a combination of Environment, Social, and Governance. In the past, companies' financial performance was the most important, but in the current investment market, the movement to reflect ESG management factors in investment decisions is strengthening. This study aims to find out degree centrality, betweenness centrality, and closeness centrality through social network analysis after collecting related keywords to derive ESG management issues of logistics companies. This study collected 2,359 news articles searched under the keywords "ESG", "Logistics". In addition, data on ESG activities were also used for analysis by referring to the sustainable management reports of logistics companies. As a result of the analysis of degree centrality, it was found that ESG management of logistics companies is in progress, focusing on small enterprises and eco-friendly keywords, and is concentrated on social responsibility and eco-friendly activities. In the betweenness centrality analysis, logistics companies such as HMM and CJ Logistics were derived in a high ranking. In the closeness centrality analysis, eco-friendly keywords topped the list, while the number of keywords related to governance was relatively small, suggesting that logistics companies need to improve their governance structure.

Introduction. In this study, purpose is to analize the types of golf tourism, inbound or outbound, by using big data and see how movement of industry is being changed and what changes have been made during and after Covid-19 in golf industry. Method Using Textom, a big data analysis tool, "golf tourism" and "Covid-19" were selected as keywords, and search frequency information of Naver and Daum was collected for a year from 1 st January, 2023 to 31st December, 2023, and data preprocessing was conducted based on this. For the suitability of the study and more accurate data, data not related to "golf tourism" was removed through the refining process, and similar keywords were grouped into the same keyword to perform analysis. As a result of the word refining process, top 36 keywords with the highest relevance and search frequency were selected and applied to this study. The top 36 keywords derived through word purification were subjected to TF-IDF analysis, visualization analysis using Ucinet6 and NetDraw programs, network analysis between keywords, and cluster analysis between each keyword through Concor analysis. Results By using big data analysis, it was found out option of oversea golf tourism is affecting on inbound golf travel. "Golf", "Tourism", "Vietnam", "Thailand" showed high frequencies, which proves that oversea golf tour is now the re-coming trends.

본 연구는 커뮤니케이션이 활발한 SNS 속에서 사회적 이슈가 어떤 주제별로 나뉘어져 있고, 어떤 키워드들이 유기적으로 연결되었는지 그 연결 관계를 알아보고자 하였다. '미투'라는 새로운 단어가 생겨남과 동시에 큰 운동으로 번지고 있는 '미투운동'을 사회적 이슈로 간주하였고, 여러 SNS 중 특히 실시간 소통이 가장 활발한 트위터를 중심으로 분석을 실시하였다. 우선 키워드를 '미투'로 하여 관련된 키워드를 각 날짜별로 추출하였고, 주요 키워드를 파악한 후 토픽 모델링을 수행하였다. 이를 통해 사회적 이슈를 둘러싼 키워드들이 시간의 흐름에 따라 어떻게 변화하였는지 파악하고, 각 토픽 내의 키워드를 종합하여 토픽별 사회적 이슈의 다양한 관점을 해석하였다.

This study aimed to analyze the research trend related on obesity in physical education in Korea through the keyword network analysis and to establish a basic database for effective design of prospective studies. To achieve it the study crawled co-occured keywords with 'obesity' and 'physical education' from RISS and analyzed the list from 1990 to 2018. They include 25 journal papers and 38 dissertations. The results are as follows. First, recent 30 years 63 papers published in Korea with 'Obesity' and 'Physical Education', and there were 144 related keywords. Second, analyzing journals which have 'Obesity' and 'Physical Education', co-occured keywords in 4 centrality were 24 keywords(student, Korea, prevention, effect, level, body, activation, actual condition, lesson, child, investigation, participation, book, cause, activity, normal, degree, nutrition, physical strength, weight, elementary, light, inquiry, health), and 37 keyword occurred in top 30. Lastly, by CONCOR analysis the result could be divided into 2 clusters. One consists of the object of obesity and its invervention, and the other consists of negative keywords of obesity and its preliminery dimenstion. Through the result, this study showed the research trend which involves the concept of obesity in physical education in Korea. Through the result, prospective obesity research in physical education in Korea would be promoted.

본 연구는 사회네트워크분석(Social Network Analysis: SNA)방법을 활용하여 최근 6년간(2010~2015년)의 국내 및 해외 영재교육의 연구동향을 분석하는 데 목적을 두었다. 연구대상은 영재교육 관련 국내 KCI등재지인 '영재교육연구'(한국영재학회)와 '영재와 영재교육'(한국영재교육학회)에 게재된 논문 457편과 해외 SSCI학술지 'The Gifted Child Quarterly,' 'Journal for the Education of the Gifted,' 'High Ability Studies'에 게재된 논문 347편으로 선정하였으며, 각 논문의 영문 키워드를 추출한 후 SNA방법으로 키워드 네트워크와 연결중심성 분석을 실시하였다. 연구결과, 국내외 공통적으로 academically gifted, science gifted, gifted를 중심으로 achievement, identification, intelligence의 키워드 빈도가 가장 높게 나타났다. 따라서 영재를 대상으로 성취, 판별, 지능에 관련된 연구들이 가장 많이 이루어진 것으로 나타났다. 이외에도 cognitive, motivation, self-concept이 공통적인 관심 주제로 나타났다. 한편 국내에서는 creativity, gifted education, gifted education teacher를, 해외에서는 foreign countries, student attitudes를 키워드로 한 연구가 주를 이루었다. 국내 영재교육 연구에서는 해외와 달리 외국사례, 학생태도, 성별차이 관련 키워드 빈도가 거의 나타나지 않았다. 결론적으로 국내 영재교육 연구는 보다 다양한 관점에서 연구가 이루어져야 하는 것으로 해석되었다.

This study is to design a Semantic Navigation Retrieval System for Oriental Medicine Articles based on a XTM so that people can search and use them more effectively than before. Keywords extracted from articles are categorized 4 topics : herbs, prescription, disease, and action. Keywords analysis Ontology is modeled based on 4 topics and their relations, and then represented Topic maps. Next, Article analysis Ontology is consist of title, author, keywords, abstracts and organization Topics from metadata. Keywords and Article analysis Ontology were integrated through Keywords Topic. Korean Medical Article Retrieval System is optimistic in terms on search results supporting semantic navigation in the information service aspects and easier accessibility because all related information are semantically connected with each different DBs.

본 연구의 목적은 키워드 특징 면에서 문헌정보 저널에서 나타나는 유사점과 차이점을 조사하여 다양한 문헌 정보학 연구 영역을 발견하는 데 있다. 이 연구를 수행하기 위해 2004 년부터 2016 년까지 네 개의 한국 저널의 키워드가 RISS 데이타베이스에서 수집 되었고(http://www.riss.co.kr) 그리고 여섯 개의 국제저널의 키워드가 SCOPUS 데이타베이스에서 수집 되었다(http://www.scopus.com). 키워드의 특징은 한국 및 국제저널에 관하여서 자주 사용 되었던 키워드와 자주 사용되었던 독특한 키워드를 검증하는 연구이었다. 독특한 키워드란 한 분야에서는 나타나지만 다른 분야에서는 나타나지 않는 키워드를 말한다. 이 연구의 결과는 다음과 같다. 가) 키워드 빈도 분석 결과는 한국의 문헌정보 학의 연구주제와 연구특색을 보여 주는 것으로 나타났다. 나) 일반적으로 한국 저널에서 사용 된 키워드는 도서관과 관련된 주제의 영역을 나타냈고, 국제 저널에 사용되는 키워드는 서지 측정법과 관련된 주제 영역을 나타냈다. 다) 빈번히 사용되었던 독특한 키워드에서도 이러한 전반적인 연구 테마를 명백히 나타냈다. 라) 어떤 키워드는 쓰이는 범위가 한 국가나 지역으로 한정되어 있는 것으로 나타냈다. 이 연구의 중요한 시사점은 가장 자주 사용되는 키워드와 가장 자주 사용되는 독특한 키워드는 둘 다 문헌정보 학의 주제 영역을 적절하게 반영하고 있는 것으로 보인다는 것이다.
