  • This study aims to find the direction of subject-divisional plan and the change of composition factors in university Library. To confront new information environment, change of service providing environment, academic characteristics of universities. and users' information needs, the collection and service of university libraries are needed to be restructured based on subject-divisional plan. To adopt subject divisional plan effectively. it is necessary to recognize necessity and reasonability of subject - divisional plan by analyzing a change of physical, intellectual, human, and user factors in the libraries from the aspect of subject-divisional plan. That is, the collection and service of university libraries should be reorganized according to the subjects along with such changes as below. First, people came to consider convenience of space and path of building inside more than past. Second, collection becomes constructed and materials are located based on effectiveness rather than logicality. Third, subject oriented service of library became active through developing the subject abilities of librarians. Fourth, users have tendency to visit libraries lot a special subject matter.

  • 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.

  • 문서에서 저자의 의도와 주제, 그 안에 포함된 감성을 분석하는 것은 자연어 연구의 핵심적인 주제이다. 이와 유사하게 특정 글에 포함된 정치적 문화적 편향을 분석하는 것 역시 매우 의미 있는 연구주제이다. 우리는 최근 발생한 한 사건에 대하여 여러 신문사와 해당 신문사에서 생산한 기사를 중심으로 해당 글의 정치적 편향을 정량화 하는 방법을 제시한다. 그 방법은 선택된 주제어들의 문장 공간에서의 거리를 중심으로 그래프를 생성하고, 생성된 그래프의 기계학습을 통하여 편향과 특징을 분석하였다. 그리고 그 그래프들의 시간적 변화를 추적하여 특정 신문사에서 특정 사건에 대한 입장이 시간적으로 어떻게 변화하였는지를 동적으로 보여주는 그래프 애니메이션 시스템을 개발하였다. 실험을 위하여 최근 이슈에 대하여 12개의 신문사에서 약 2000여 개의 기사를 수집하였다. 그 결과, 약 82%의 정확도로 일반적으로 알려진 정치적 편향을 예측할 수 있었다. 또한, 학습 데이터에 쓰이지 않은 신문기사를 활용하여도 같은 정도의 정확도를 보임을 알 수 있었다. 우리는 이를 통하여 신문기사에서의 정치적 편향은 작성자나 신문사의 특성이 아니라 주제어들의 문장 공간에서의 거리 관계로 특성화할 수 있음을 보였다. 할 수 있다.

  • This study purposed to reveal the process of change in dismissed workers' experiences at dismissal and the subsequent period of unemployment. For this purpose, six dismissed workers' psychological experiences were explored using the phenomenological method as one of qualitative research methods. Data were collected through in-depth interviews with the workers on their psychological experiences at dismissal, continuous psychological or physical changes after dismissal, current state, etc. and from the analysis of the data were derived 12 sub-themes and they were categorized into four main themes. The four main themes were 'emotions experienced with dismissal,' 'psychological and physical symptoms,' 'patterns of social perception,' 'and ways of coping with dismissal.' The main themes and their sub-categories were described, and dismissed workers' specific experiences related to them were explained. Lastly, dismissed workers' changes and experiences were discussed based on previous studies.

  • The purpose of this study was to analyze domestic research trends over the past 20 years and future direction of forest ecology using text mining. A total of 1,015 academic papers and keywords data related to forest ecology were collected by the "Research and Information Service Section" and analyzed using big data analysis programs, such as Textom and UCINET. From the results of word frequency and N-gram analyses, we found domestic studies on forest ecology rapidly increased since 2011. The most common research topic was "species diversity" over the past 20 years and "climate change" became a major topic since 2011. Based on CONCOR analysis, study subjects were grouped intoeight categories, such as "species diversity," "environmental policy," "climate change," "management," "plant taxonomy," "habitat suitability index," "vascular plants," and "recreation and welfare." Consequently, species diversity and climate change will remain important topics in the future and diversifying and expanding domestic research topics following global research trendsis necessary.

  • The objective of the article is to find the research trends and the main traits presented in the keywords on abstracts of research articles of "International Journal of Education Development" from 2002 to 2017. To do this, Text Network Analysis(TNA) was applied targeting 966 papers on the journal and the major research outcomes are as follows. First, the frequency analysis on the keywords showed that the keywords like Administration of education program, Schools and instruction, Regional public administration, Educational support service, Elementary education, and Elementary and secondary school were analyzed more than 100 times and also high in centrality degree. Second, the analysis results of the keywords presented in those research articles by development goal periods showed that several new keywords like Elementary education, Elementary and secondary school, Education quality, Secondary education, Educational planning have emerged frequently after SDGs and these keywords showed high in their centrality analysis. Third, the analysis on education level showed that the keywords like Elementary education, Administration of education program, School children were high in frequency and centrality degree in Elementary level. In secondary level, Schools and instruction, Administration of education program, Academic achievement were high, and in high level, college and university was high, respectively.

  • As information technology advances and changes in the library environment, a flexible view and reinventing perspective of LIS research is necessary. This study focused on the investigation of the recent(2000-2003) research trends by analyzing the contents of articles from the major academic research journals for getting a future oriented view of the field. A taxonomy developed by Hawkins(2003) was applied in order to find out the major pattern of research in the domestic as well as international LIS Journals, and Chi-Square Tests Analysis was used to figure out if the research pattern has any effect on research environment(vice versa).
