I would like to trace back periodic social trend by searching if regular performance might have reflected on social trend on its theme by analyzing theme trend of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do and to provide the meaningful results for further study by checking if the theme of dancing performance is in relation with social structure. To perform this research, I had studied on previous thesis and reference books. For example, I selected three groups, of The National Dance Company of Korea, Dance Company of Seoul city, Dance Company of KyungKi-Do, to research their theme of regular performance through checking previous thesis related to, performance material, news articles, pamphlets from beginning to present. How to analyze is being proceeded from foundation of dancing company to present according to Kim Byungseok's classification method, which was consistently used for searching theme trend from previous study as below; 1) Theme based on traditional conscious,2) Theme based on Literature, 3) Theme based on Historic issues, 4) Theme based on abstract, 5) Theme based on reality, 6)Theme based on social issues.

Purpose: Health technology research & development is an important area to leading future. This study examined the current trends for 'oncogene' based on the research subject network to deduce a research front. Method: Papers were extracted from PubMed database using MeSH term for studies on 'oncogenes' and further categorized as papers published by Korean. Keywords were collected from all of articles. Research subject network was generated by keywords. Research subject network was analyzed by weighted degree centrality based social network analysis and transition of research subjects was analyzed by the time series. Results: On 'oncogenes', 'Genes, ras', 'Apoptosis', 'Signal Transduction' had a high degree centrality and currently 'Antineoplastic Agents', 'Prognosis', and 'Tumor Markers, Biological' were widely conducted. Conclusion: Consistency of research trend pattern was found by analyzing oncogene network with compromised to international vs. domestic trends. Analyzing keyword networks in various subject area, those will allow us to predict the research progress and propose evidence of research & developmental strategy.

논문에 부여되는 저자 주제어(author keyword)는 논문을 분류 및 검색하는데 활용될 수 있다. 이렇게 주제어를 부여할 때 자동으로 저자 주제어를 추천한다면 사용자에게 편리성을 제공하고 저자가 직접 부여한 저자 주제어 이외에 추가적으로 주제어가 있는지도 확인할 수 있어 유용하다. 본 연구에서는 논문에 달려있는 다수의 주제어 중 하나의 주제어를 선별하여 Labeled LDA를 이용해 주제어와 초록(abstract)의 관계를 학습했다. 이후 초록이 주어지면 자동으로 저자 주제어를 부여할 수 있도록 추천하는 기법을 제안하고 그에 따른 실험을 진행했다. 본 논문에서는 실험을 통하여 기계학습을 이용한 저자 주제어의 추천이 어느 정도의 성능을 보이는지 평가하고 향후 연구의 방향을 제시한다.

Second, the necessity of adopting subject divisional plan is to secure enough subject librarians and large space These necessities must be fulfilled prior to adopting the subject divisional plan. Third subject divisional plan model for efficient reference service of university library is 'wide-area subject divisional plan model'. 1) In the case of central library, the space model of wide-area subject divisional plan is programmed as undergraduate library for the undergraduate students. And each subject libraries is operated as research library for the professors and graduate students. 2) In central library, the collection model of wide-area subject divisional plan is practiced as offering reference and general education centered data for undergraduate students 'study. And each subject libraries is furnished with research papers, recent journals, and various major-related data. 3) The human resource model of wide-area subject divisional plan is applicated by arranging appropriate librarians at the right place. In the case of central library, the reference librarians and librarians who educate the users and take charge of function are set in to help undergraduate students with their study. Subject library needs to secure subject librarians, librarians who take charge of function, and graduate students who are related to the subject as student assistant. Then it is possible to discriminate reference service by subjects and users.

At the time of operating and studying the subject special librarians of university libraries, an aim of this study is to seek the ways for the users to be aware and make the best use of them, and to receive the necessary assistance from them. To achieve this, I examined carefully the operation and management states, and surveyed and analyzed the actual users' awareness of these operations. Furthermore, I investigated the way to improve the required qualifications to be subject-special librarians and the users' awareness of them. Therefore, I finally examined the way how they reconsidered the actual users in the university libraries.

We would generally use subject terms such as subject indexing for searching and accessing documents. So then, there must be any relationship between document's full-text and its subject terms. This study is started in this question. Master's theses in field of science and technology are worked with because full-text is relatively formatted. This study is to study locations of subject term on Thesis, distribution patterns of subject terms on content of full-text; 'Contents', 'Introduction', 'Theory', 'Main subject', 'Conclusion' and 'References'. Thesis were averagely composed of 1226.3 terms. And Subject terms were averagely compose of $12{\sim}13$ terms. As a result, 'Contents' and 'Introduction' have had the most frequency of subject.

주제어는 정보 서비스를 비롯한 여러 응용 분야들에서 유용하게 사용되는 지식이지만, 주제어 간 관계가 다양할 뿐만 아니라 목적에 맞도록 개별적으로 설계됨으로써 주제어 관계 속성 유형과 무관하게 공유가 가능한 주제어 공통 표현 모델이 제시되지 못하였다. 본 연구는 응용 분야, 온톨로지 종류와 무관하게 적용될 수 있으며 시맨틱 웹 서비스 간 공유가 가능한 주제어 공통 표현 모델을 제시하고자 한다. 이를 위해, 주제어 관계를 범용 클래스로 정의하고, 주제어 관계 속성 유형을 데이터타입 속성 (Datatype Property)으로 선언하였다. 또한, 주제어 역시 그 속성 유형을 데이터타입 속성으로 선언하였는데, 결국 다양한 유형의 관계들을 용이하게 표현할 수 있도록 하기 위한 것이다. 실험을 위해 주제어 간 관계수가 70,804,233개이며 주제어 관계 속성 유형이 4가지인 과학 기술 기반 정보 온톨로지와 주제어 간 관계수가 44,147개이며 주제어 관계 속성 유형이 13가지인 표준 정보 온톨로지를 대상으로 본 연구에서 제안한 주제어 공통 표현 모델을 적용하였으며 총 284,744,802개의 RDF(Resource Description Framework) Triple을 생성하였다.

It has been demonstrated through previous demand analysis that the subject-oriented service system in university libraries are in higher demand than the function-oriented system. Despite of the increasing number of studies that prove cost-effectiveness and operational efficiency of the subject-oriented library service, there are virtually no university libraries in Korea that fully operate subject-oriented service. This study aims to propose a set of practical guidelines for university libraries to introduce subject-oriented service in the midst of many existing constraints, namely staff shortage. The study describes responsibilities of subject specialist librarians and analyzes best practices of subject-oriented service. Also it shows current standing of university libraries of difference size based on web site research of four-year university libraries.

The purpose of this study was to propose the improvements for high quality of National Library of Korea (NLK) Subject Headings List which was developed as a subject access tool in 2002. For this study, literature review, case study for subject headings lists of national libraries, and data analysis of headings and relationships were performed. Several problems were found as follows: inconsistency of subject headings descriptions, unclear and unnecessary relationships among headings, inconsistency of hierarchical relationships, lack of currency, incorrectness of classification numbers, duplication of newly requested terms, and assignment of non-preferred and unregistered terms in bibliographic records. Focusing on these problems, modifications of subject headings and bibliographic records, installation and operation of an review committee on subject headings, and supplementation of a manual were suggested to improve NLK Subject Headings List.
