It is our main aim in this study to discriminate the conceptual relationship between homographic descriptors. The roles of qualifier and the problems of the recent usage of qualifier such as Hangul, Hanja and foreign languages, which is based largely on the dictionaries, subject heading lists and thesauri, re analyzed within the framework of the our test thesaurus developed as a macro-the-saurus. Finally, we proposed some new ideas must be integrated into the Hangul qualifier in order to make it generally applicable within the field of dictionary, and the method of representing, selection principles and priority of Hangul qualifiers.

When Web-based special retrieval systems for scientific field extremely restrict the expression of user's information request, the process of the information content analysis and that of the information acquisition become inconsistent. Accordingly, this study suggests the re-ranking retrieval model which reflects the content based similarity between user's inquiry terms and index words by grasping the document knowledge structure. In order to accomplish this, the former constructs a thesaurus and similarity relation matrix to provide the subject analysis mechanism and the latter propose the algorithm which establishes a search model such as query expansion in order to analyze the user's demands. Therefore, the algorithm that this study suggests as retrieval utilizing the information structure of a retrieval system can be content-based retrieval mechanism to establish a 2-step search model for the preservation of recall and improvement of accuracy which was a weak point of the previous fuzzy retrieval model.

Oral history is the work to make the record of the verbal content recreated by the memories of the survivors. Oral history recording is accomplished through the collaboration of the interviewee, the interviewer, the cameraman, the recorder, the transcriber and etc. Therefore, it is important for the context at the time of the production to be expressed. So planning for the collection of oral records, the collection of oral records, and their preservation and maintenance should be managed systematically. This study, being started from this sense of problem, designed conceptual model of metadata to well reflect the contextual characteristics of the oral records of the women life of among the oral records and extracted the elements through this. The whole process of records management including from planning, production, preservation, management, and leading to use, related to the oral records of the women life, was classified into a hierarchy. It also proposed the system which can express the characteristics of the 'gender' through authority records and subject thesaurus.

This study compares and analyzes the numbers and characteristics of Korea-related subjects included in the 2008 Japanese edition of the National Diet Library Subject Headings (NDLSH) and the $2^{nd}$ edition of the Chinese Classified Thesaurus(CCT). The analysis results show that 258 subjects, approximately twice as many as 137 subjects in CCT, were found in NDLSH. There are more pure subjects that exclude the references in CCT than in NDLSH. On the other hand, much more subjects are found in NDLSH in the event that personal names, corporate headings, and subjects combined with detailed headings are included. Meanwhile, more subjects are relatively engaged in the fields of politics, diplomacy, and military in CCT because CCT is characterized by socialism and by being a pro-North Korea. Moreover, the considerable numbers of subjects reflecting North Korea's viewpoint are included in CCT. NDLSH changed only recently the names of both South and North Korea into the "Republic of Korea" and the "Democratic People's Republic of Korea", respectively. On the other hand, CCT more frequently uses "Joseon" than "Korea", and the distinction between the names is unclear. CCT thoroughly supports the stance of the developed country, directly involved in the disputable subjects between two countries such as "Dokdo", "the East Sea", "Dumangang", and "Baekdusan". Both heading lists consider "Balhae" as part of Chinese history in CCT, which has ignored the position of Korea.

The purpose of this study is to explore ways to improve accessibility to school library materials through analysis of elementary school students' information search behavior in DLS. Accordingly, the DLS search process was recorded for 26 students attempting a DLS search in the school library, and data was collected through a pre-search questionnaire on overall information needs and a post-search questionnaire on the search process and results. As a result of the analysis, satisfaction was found to be low when the main purpose of DLS use was simple leisure reading, when the search time and number of search words were long, and when there were too many search results. Accordingly, it was emphasized that curriculum subject-related metadata elements should be developed and a curriculum subject-specific thesaurus should be built and used to build lists and support user searches. In addition, it was suggested that the basic functions provided in external searches should be included, and a foundation should be laid in terms of resources and curriculum to systematically provide information utilization education to elementary school students who lack the ability to select search terms and judge the suitability of results after the search. It was proposed to provide an integrated search service with external resources and a personalized book recommendation service.

This study examined the method for adding related to "stomach neoplasms" as filters to the Medical Subject Headings (MeSH) for search as well as a method for improving the search efficiency through a word-proximity search by measuring the distance of co-occurring terms. A total of 8,625 articles published between 2007 and 2016 with the major topic terms "stomach neoplasms" were downloaded from PubMed article titles. The vocabulary to be added to the MeSH for search were analyzed. The search efficiency was verified by 277 articles that had "Stomach Neoplasms" indexed as MEDLINE MeSH in KoreaMed. As a result, 973 terms were selected as the candidate vocabulary. "Gastric Cancer" (2,780 appearances) was the most frequent term and 7,376 compound words (88.51%) combined the histological terms of "stomach" and "neoplasm", such as "gastric adenocarcinoma" and "gastric MALT lymphoma". A total of 5,234 compounds words (70.95%), in which the co-occurring distance was two words, were found. The matching rate through the MEDLINE MeSH and KoreaMed MeSH Indexer was 209 articles (75.5%). The search efficiency improved to 263 articles (94.9%) when the search filters were added, and to 268 articles (96.7%) when the 13 word-proximity search technique of the co-occurring terms was applied. This study showed that the use of a thesaurus as a means of improving the search efficiency in a natural language search could maintain the advantages of controlled vocabulary. The search accuracy can be improved using the word-proximity search instead of a Boolean search.
