Properties of Ag thick films fabricated by using low temperature curable silver pastes were investigated. Ag pastes were consisted of polymer resins and silver powders. Ag pastes were used for conductive or fixing materials between board and various electrical and electronic devices. Low temperature curable Ag pastes have some advantages over high temperature curable types. In cases of chip mounting, soldering properties were required for screen printed Ag thick films. In this study, four types of Ag pastes were fabricated with different compositions. Screen printed Ag thick films on alumina substrates were fabricated at various curing temperatures and times. Thickness, resistivity, adhesive strength and solderability of fabricated Ag thick films were characterized. Finally, Ag thick films produced using Ag pastes, sample A and B, cured at $150^{\circ}C$ for longer than 6 h and $180^{\circ}C$ for longer than 2 h, and $150^{\circ}C$ for longer than 1 h and $180^{\circ}C$ for 1 h, respectively, showed low resistivities of $10^{-4}$ $∼10^{-5}$ Ωcm and good adhesive strength of 1∼5 Mpa. Soldering properties of those Ag thick films with curing temperatures at solder of 62Sn/36Pb/3Ag were also investigated.

The purpose of this study is to improve the ability to select good encyclopedias by analyzing the evaluation points for print encyclopedias. For this purpose, it investigates S evaluating categories suggested in the related literatures, such as purpose & scope, authority, accessibility, writing style and characteristics & cost, and then draws and analyzes in detail the specific evaluation points under each categories. In the process of analysing special emphasis is placed on the theoretical appropriateness to each evaluating points, not simply suggesting another evaluation points. 본 연구는 인쇄본 백과사전의 평가요소를 추출하고 이를 분석함으로써 이상적인 백과사전을 선택할 수 있는 능력을 제고시키는데 목적을 둔다. 분석방법은 평가내용을 목적과 범위, 권위, 접근성, 기술형식, 형태, 특징과 가격 등의 여섯 가지 범주로 나누고 각 범주 아래에서 세부적인 평가요소를 추출하여 분석하였다. 분석은 단순히 평가요소를 제시하는 것이 아니라 각 평가요소별로 이론적 당위성을 제시하는데 중점을 두었다.

박준식,문정순,Park, Joon-Shik,Moon, Jung-Soon 한국문헌정보학회 2000 한국문헌정보학회지 Vol.34 No.1

본 연구는 기존의 인쇄본 백과사전 평가이론에 근거하면서도 CD-ROM 백과사전에 적합한 체계적인 평가기준을 개발하여 우수한 CD-ROM 백과사전을 선정, 구입하기 위한 지침을 마련하는데 목적을 둔다. 따라서 본 연구에서는 CD-ROM 백과사전의 평가기준을 도서관에서 CD-ROM 백과사전을 선정, 구입하는데 필요한 평가과정에 따라 서평지의 평가, 기본이 되는 인쇄본 백과사전, 시험용 디스크의 이용가능성, 하드웨어의 요구사양과 소프트웨어 설치의 용이성, 데이터베이스의 내용, 검색 소프트웨어, 단독 사용형과 네트워크용, Standard판과 Deluxe판, 가격의 9가지 범주로 나누고 각 범주 아래에서 세부적인 평가요소와 항목을 제시하였다. This study aims to provide a guide to the selection and purchase of a good CD-ROM encyclopedia by establishing evaluation criteria for CD-ROM encyclopedia. This study first divided evaluation criteria into the following rune categories: reviews available, print version, availability of trial disc, hardware requirements and ease of software installation, database contents, retrieval software, standalone/network version, standard/deluxe version, costs. Next, it suggested evaluation points and items in detail under each category.

Cutter-Sanborn 저자기호표에 관한 분석적 고찰

박준식,Park Joon-Shik 한국문헌정보학회 1992 한국문헌정보학회지 Vol.23 No.-

The purpose of this is to evaluate the contents through the anal us is of the merits and demerits, and its special quality of the Cutter-Sanborn Three-figure Author Table. table. The abstract of this study is as follows : With the results of the analysis of Cutter-Sanborn's Tabls, several advent-age were found in the area of enumerative-ordinal numbering system, mixed notation, and information retrieval. A defect is that each corporate author and serials and reference book's titles are difficult to be numbered, and there is serious diviation in percentages of the numbers assigned to each letter because each letter apportion rate was applied without any criteria. Such phenomenon decrease the effectiveness as author notation in several letters. The separation of headings are seriously unbalanced because the separation of heading is not consistent with actual publishing trends. This phenomenon made difficult individualization of materials in several letters.

정보봉사의 속성과 철학적 기반

박준식,Park, Joon-Shik 한국도서관정보학회 2010 한국도서관정보학회지 Vol.41 No.2

이 논문은 정보봉사의 개념과 속성을 밝히고, 이를 토대로 정보봉사의 철학적 기반을 세우는데 목적을 두었다. 정보봉사의 개념과 속성은 용어의 어원과 정의 및 내용, 역사적, 사회적 관점에서 그 근거를 밝혔다. 이를 통해 정보봉사라는 용어가 정보봉사의 본질과 속성 그리고 활동내용에 가장 적합한 명칭임을 논리적으로 증명함으로써 정보봉사의 이론을 체계화하였다. 정보봉사의 철학은 용어의 어원, 정의, 기능, 그리고 역사적, 사회적 관점 등에서 일관되게 흐르고 있는 정신인 교육, 정보, 상담 지도라는 세 요소와 봉사라는 인본주의적 요소를 중심으로 그 기초를 세우는 작업을 시도하였다. The purpose of this paper is deriving philosophical foundations of information services by clarifying its concepts and attributes. Clarifying its concepts and attributes is based on the origin of the term information services, definitions and contents, historical and social perspectives. The theory of information services was reorganized by logically demonstrating that the term "information services" is most suitable name to represent its essence, attributes, and activities. The philosophy of information services has the key elements as instruction, information, guidance, and service in humanistic aspects which have been shown consistently in the origin of the term, definitions, historical and social perspectives. This paper tried to establish philosophical basis for information services that is focused on these elements.

참고봉사의 이념과 기준설정을 위한 고찰 -미국에서의 이론과 전개과정을 중심으로-

박준식,Park Joon Shik 한국문헌정보학회 1981 한국문헌정보학회지 Vol.8 No.-

This study has two aims. one is to devide the ideology of reference service into three groups such as conservative, moderative, and progressive theories, and then investigate the validity of each theory as well as any problems to be suggested. The other is to establish appropriate standards of reference service according to the types of libraries and users, based on the analysis of such theories. Each theory has its own merits and demerits. Accordingly, it seems to be difficult to apply uniformly and theory into users who have different types of question and educational levels. And also it is difficult to apply into various libraries which have different aims of establishment, characteristics, and the users of each library. Consequently, it is suggested to set up a norm of reference service according to the types of libraries and users respectively. The conservative theory is applicable to small and medium sized public libraries, school libraries, and college and university libraries of which the users are mainly students and citizens. The progressive theory is desirable for special and academic libraries as well as large public libraries where the users are mainly specialists. and scholars.
