Library & Information Science in Korea has developed its curriculum corresponding to the rapidly changing social needs. Upon the arrival of information society, a series of structural adjustments were implemented including renaming the department, underpinning the sector of Information Science and Information Service. and opening new courses such as Archives and Records Management. Also, the overall course design has been fully modified in line with the newly adopted mechanism of major selection in the undergraduate academic program. This paper aims to explore the influence of the structural shifts in our society on the sector development of the Library & Information Science by an extensive comparative analysis on the variation of academic curricula before and after the new major selection system and the emergence of information society.

The purpose of this study is to describe the information environment of ST information users in Korea by examining their needs and satisfaction for documents. Comparison was made between the statistics of KISTI DDS and NACSIS-ILL document copy service, and data from the survey conducted for KISTI's ST information users in 2001 were analyzed. Findings include the low demand for documents delivery, low success rate in obtaining documents from domestic institutions, including KISTI, relatively high reliance on foreign DDS institutions, and difficulties in getting documents with speed, timeliness, and cost-effectiveness. It seems urgent to implement the strategic plans for more comprehensive and well-organized collection development and resource-sharing, and improvement of DDS.

최근 인용 네트워크 분석을 통해서 단일 문헌의 인용 영향력을 측정하려는 시도가 다양하게 전개되고 있다. 널리 알려진 PageRank를 보완하려는 일부 시도와 함께 h-index를 단일 문헌의 인용 영향력 측정에 적용한 단일문헌 h-index도 제안되었다. 이 연구에서는 Web of Science에서 검색한 계량정보학 분야 문헌집합을 대상으로 여러 측정 방식의 특징을 비교해본 후, 새로운 인용지수 2종을 제안하였다. 제안한 인용지수는 PageRank처럼 전역 네트워크 분석 방식인 지수 1종과 h-index처럼 지역 네트워크 분석 방식인 지수 1종으로서 상황에 따라 선택하여 사용할 수 있다.

Information extraction can facilitate the intensive analysis of documents by providing semantic triples which consist of named entities and their relations recognized in the texts. However, most of the research so far has been carried out separately for named entity recognition and relation extraction as individual studies, and as a result, the effective performance evaluation of the entire information extraction systems was not performed properly. This paper introduces two models of end-to-end information extraction that can extract various entity names in clinical records and their relationships in the form of semantic triples, namely pipeline and joint models and compares their performances in depth. The pipeline model consists of an entity recognition sub-system based on bidirectional GRU-CRFs and a relation extraction module using multiple encoding scheme, whereas the joint model was implemented with a single bidirectional GRU-CRFs equipped with multi-head labeling method. In the experiments using i2b2/VA 2010, the performance of the pipeline model was 5.5% (F-measure) higher. In addition, through a comparative experiment with existing state-of-the-art systems using large-scale neural language models and manually constructed features, the objective performance level of the end-to-end models implemented in this paper could be identified properly.

본 연구는 미국 ALA (American Library Association)가 인정한 문헌정보학 석사과정 (Master of Library Services) 교육과정에서 연구방법론의 현황과 특성을 분석하고, 문헌정보학 프로그램이 개설된 기관 내 다른 대학원 프로그램에서의 연구방법론의 위상을 문헌정보학과와 비교하였다. 연구결과 문헌정보학의 경우, 연구방법론에서 다루어지는 내용들이 매우 다양하고 일관성이 없었으며, 다수의 문헌정보학 프로그램들 내에서 연구방법론이 필수과목이 아니었으며, 상위20위에 드는 학교 중 절반만이 연구방법론을 필수과목으로 요구하였다. 그러나, 문헌정보학 프로그램이 개설된 기관 내의 자연과학 프로그램, 대부분의 사회과학 프로그램, 경영학 석사과정 (MBA), 사회복지학 석사과정들이 연구방법론을 핵심과목으로 요구하였으며, 이들 분야들은 자신의 분야의 특수성을 반영하는 연구방법론 과목을 개설하였다. 또한 이들 분야의 프로그램들을 승인하는 국가적인 기관들이 연구방법론의 필수과목 개설을 명시하였다. 털 연구는 문헌정보학의 학문적 경쟁력을 강화하고, 연구의 질을 향상시키기 위해서는, 문헌정보학 학문의 특수성을 반영할 수 있는 연구방법론의 개발과 연구방법론의 핵심과목 지정이 중요함을 제시한다.

Protein structure is highly related to its function and comparing protein structure is very important to identify structural motif, family and their function. In this paper, we construct an integrated database system which has all the protein structure data and their literature. The structure queries from the web interface are compared with the target structures in database, and the results are shown to the user for future analysis. To constructs this system, we analyze the Flat-File of Protein Data Bank. Then we select the necessary structure data and store as a new formatted data. The literature data related to these structures are stored in a relational database to query the my kinds of data easily In our structure comparison system, the structure of matched pattern and RMSD valure are calculated, then they are showed to the user with their relational documentation data. This system provides the more quick comparison and nice analyzing environment.

In this study, it was investigated if there were some differences on the preference of researchers to grey literature among seven different subjects in the field of science and technology using citation analysis. The result shows that there were some differences among researchers, depending on the subject area. It also appears that the preference of grey literature of researchers is dissimilar in journals in English and journals in Korean, regardless of the subject area. Finally, partial correlation coefficient among nine different types of material was counted with the control of languages used and subject areas included. Among nine types of cited documents, the value of partial correlation coefficient between proceedings and miscellaneous is larger than that of any other coupled comparison This means that researchers who cite articles from proceedings tend to include information from miscellaneous at the same time.
