In Korea tumors occurred frequently, and the tumor medicine used to treat them developed. Because tumors due to Koreans' physical constitution and environment and there has always been an impeding need for a cure, traces of such efforts can be found throughout Korean medical history. During the mid-Chosun dynasty, the government founded a government office that specialized in curing tumors. This study observes the establishment and operation of this institution.

Lisangsokdanbang is the oldest known medical document in existence. It is, however lost-its original copy could not be traced. But the contents of Lisangsokdanbang quoted in Uibangyuchwi, a document published in Chosun in 1447. Thus this study aims to restore the contents of Lisangsokdanbang based on Uibangyuchwi and present the synthesis of facts on Lisangsokdanbang extracted from the reference books.

In this paper, controller propose to prevent compressor surge and improve the transient response of the fuel flow control system of turbojet engine. Turbojet engine controller is designed by applying Artificial Neural Network PID control algorithm and make an inference by applying Levenberg-Marquartdt Error Back Propagation Algorithm. Artificial Neural Network inference results are used as the fuel flow control inputs to prevent compressor surge and flame-out for turbojet engine for UAV. High Gain Observer is used to estimate to compressor rotation speed of turbojet engine. Using MATLAB to perform computer simulations verified the performance of the proposed controller. Response characteristics pursuant to the gain were analyzed by simulation.

Purpose: The purpose of this study was to identify attitudes of adolescents toward suicide. Methods: Q-methodology which provides a method of analyzing the subjectivity of each item was used. Thirty middle and high school students classified 37 selected statements into a normal distribution using a 9 point scale. Collected data were analyzed using the Quanl PC Program. Results: Three types of attitudes toward suicide were identified. The first type (opposing suicide-moral minded) showed an attitude of opposing suicide and thinking that suicide is a sin. The second type (understanding-empathizing suicidal person) showed an attitude of understanding the situation of the adolescents who has suicidal ideation and empathizing with them. The third type (ambivalent attitude) showed an attitude of understanding the suicidal person but, at the same time, opposing suicide. Conclusion: Results of the study indicate that different approaches to suicide prevention programs should be developed based on the three types of suicide attitudes among adolescents.

플라즈마 화학증착법(PECVD)에 의해 실리콘 (100) 기판 위에 3C-SiC막을 증착하였다. 증착반응시 유입가스비, R$_{x}$[=CH$_4$/(CH$_4$+H$_2$)]에 따른 증착막의 결정성에 대해 검토하였다. 증착된 3C-SiC막의 결정성은 R$_{x}$ 값이 감소할수록 더욱 향상되었으며, 형성된 결정상은 (111) 면으로 최대의 우선배향성을 가졌다. Nanoindentation 방법을 이용하여 3C-SiC막의 압입깊이에 따른 경도 및 탄성계수를 측정하였으며, 유입가스비(R$_{x}$)의 변화에 따라서 막의 경도 및 탄성계수가 뚜렷이 변화하였다.

The objective of this study is to provide the basic data for the elements and form of bibliographic reference for citing internet sources. The analysis study through various styles were conducted for the purpose. In this paper, documentation styles recommended by MLA APA, CBE and Chicago manual, IS0690-2, SIST-02 are introduced. And, elements and forms of documentation styles for documenting information are carefully analyzed. Also, examples of reference for documenting internet resources were followed.

This study is to investigate the problems in mapping between MARC data and Dublin core metadata, and to evaluate metadata as a source of cataloging. In addition resource description framework and its XML syntax for processing metadata in different format were analyzed in the view from encoding and transporting metadata in the network environments.

As the OPAC has been changed by the automation of library catalog, AACR2 recognized as internationally standardized Cataloging Rules, and MARC transforming to automation program have some partial irrationality. In this study, I presented the methodology improving practically and specifically Cataloging Rules adjusted to Online environment, especially centering on AACR2R, after I reviewed the literature asserting a criticism and a renewal of AACR2 and MARC.

The goal of this paper is mainly to review and summarize the theory of cataloging. This artical reviews the theortical background of cataloging. First, the objectives and function of the library catalog was analyzed. Second, According to this methodology was researched the Cutter's theory of 'convenience of the public' on the cataloging, Osborn's 'the Crisis of Cataloging' (legalist theory of cataloging, perfectionism theory bibliographic theory and pragmatic theory) and Lubetzky's the theory of 'Cataloging Rules and Principles' and the last Houten' s 'In the Iron Age of Cataloging' theory.

This study examined issues of copyright relating to digitization of bibliographic data, copyrighted works, factual data, and manpower's data that the library have. It analyzed issues of copyright relating to the use of digital works and linking. Also It investigated legal issues related information service for user in the library and digital transmission service on need of user out of the library. Finally. this paper proposed basic task for solving issues of copyright in the context of digital libraries.
