연구 개발자들은 자신의 정보활동에 있어 전체 활동의 20 ${\sim}$ 40%를 관련 정보의 탐색 및 분석에 사용하고 정보활동 결과는 개인 컴퓨터에 저장한다. 그러나 개인 컴퓨터상의 유용한 정보는 정보관리 및 공유 도구의 부재로 인하여 가치 및 유용성을 상실하고 있다. 본 연구에서는 데스크 탑 서치와 P2P 기반의 정보공유 기능을 갖는 시스템을 제안한다. 데스크 탑 서치를 통하여 연구 개발자는 본인의 컴퓨터에 저장된 정보를 효율적으로 활용할 수 있다. 연구 개발자들이 많은 시간을 들여 축적한 유용한 정보자원을 쉽게 공유할 수 있게 하는 P2P 기반의 정보공유는 연구개발 활동의 전체적인 생산성을 높일 수 있다.

The sweetpotato whitefly, Bemisia tabaci, is the major insect pest that transmitted over 100 plant viruses including tomato yellow leaf curl virus (TYLCV) of tomato plant as virus vector in the world. In this study, cDNA library of whitefly was constructed using Gateway system for selecting target gene in order to control of B. tabaci using virus-induced gene silencing (VIGS) vector with RNAi. First of all, when using oligo d(T) rimer, the calculated titer of cDNA library was confirmed with $1.4{\times}10^4$ clones and average insert sizes was confirmed with 1 kb. However, insert size was very big for construction of cDNA. Otherwise, when using attB-N25 random primer and sonication for 6 sec, the calculated titer of cDNA library was confirmed with $1.04{\times}10^5$ clones. But mostly insert band wasn't identified on the electrophoresis, because it seemed that insert size is too small (${\leq}100bp$), also the size of identified insert was somewhat big. Finally, when using oligo d(T) primer and sonication for 1 sec, cDNA insert of whitefly was appropriated for VIGS with 300-600 bp. However, cDNA sequence included a poly A and titer was very low to $5.2{\times}10^2$ clones. It was supposed that heat shock transformation was used instead of electro-transformation. It is considered that when constructing cDNA library for using VIGS vector, (1) random primer should be used for First strand cDNA synthesis in order to remove poly A and (2) sonication for 1 sec should be performed in order to get appropriated insert size and (3) electro-transformation should be performed in order to improve transformation efficiency.

도서관이 이용자에게 장애가 없는 도서관 서비스를 제공하기 위해서는 OPAC의 접근성과 검색성을 향상시키고, 도서의 검색, 식별 및 브라우징의 도구로써 ISBN의 활용가치를 높이는 것이 필요하다. 북마크릿은 웹브라우저의 '즐겨찾기에 추가' 또는 '연결(Links)' 툴바에 저장할 수 있는 작은 크기의 자바스크립트이다. 그리고 오픈소스인 북마크릿은 온라인서점의 웹페이지에서 ISBN을 추출한 다음, 해당 ISBN으로 도서관의 OPAC에서 도서를 검색할 수 있는 간단하지만 강력한 검색도구이다. 본 연구에서는 도서관 정보시스템의 새로운 환경인 Web 2.0, Library 2.0, OPAC 및 북마크릿에 대해 개괄적으로 고찰하였다. 그리고 해외에서 개발되어 활용되고 있는 네 가지 유형의 북마크릿에 대하 적용 사례를 비교 분석하고 그 특징과 장 단점을 정리하였다. 이를 통해서 국내 도서관의 OPAC과 온라인서점에서 북마크릿을 활용한 LibraryLookup 서비스 제공방안을 제안하였다.

The purpose of this study is to investigate the research trend of information user studies. The following findings are made. The literature on information user studies during 1980-1990 reveals 120 titles. The faculty members of university tend to publish their results in scientific journals and university publication while non-faculty members are more likely to represent their research papers in unpublished master thesis and bulletin. Subject distribution of research were classified into ten: user studies, material use studies, information needs and uses, user education, library use pattern, citation analysis, journal use, catalog use, information system, non-use study. Survey research, literature research, survey reserch and literature research use jointly, experimental research and citation analysis were employed for information user studies.

The author discusses about the collection development of old/rare collections in the university libraries. The method of this study is based upon the author's experiences at the University libraries and literature searching. Following items are discussed: (1) The characteristics and flow of old/rare books (2) Collection policies of old/rare books at the University libraries (3) Practical problems of the acquisition works concerning old/rare books (4) The conservation and weeding of old/rare book collection.

새로운 정보환경과 기술변화로 도서관 시스템에도 많은 요구변화가 생겨나게 되었다. 이와 같은 변화의 대안으로 나타나고 있는 것이 오픈소스 소프트웨어(Open Source Software)다. 해외에서는 도서관 오픈소스 소프트웨어의 필요에 의해 현재 발전.보급되고 있는 실정이다. 본 연구에서는 국내 관종별(공공, 대학, 전문)도서관의 도서관 시스템 현황과 해외 오픈소스 소프트웨어보급 및 판매 현황을 조사하여 분석하였다. 현황조사와 분석결과를 통해 국내 도서관의 오픈소스 소프트웨어 도입의 필요성을 제기하고자 한다.

사회 전반에 걸쳐 소셜네트워크서비스의 영향력이 높아짐에 따라 국내 대학도서관에서도 소셜네트워크서비스의 도입을 통해 이용자와 소통하려는 노력을 하고 있다. 이에 본 연구에서는 국내 대학도서관의 소셜네트워크서비스의 현황을 파악하고 소셜네트워크서비스의 이용률이 높은 도서관과 낮은 대학도서관을 선정하여 이용 및 비이용 요인을 도출하는 것을 통해 활성화 방안을 제시하였다.

In this Analysis using the evaluation data of public libraries located in Chungcheongnam-do, we compared and analyzed whether there was a difference in the average between the evaluation groups according to the size and institution of the public library, and analyzed the factors influencing the number of visitors to public libraries. The research data used public library evaluation data conducted in Chungcheongnam-do in 2020, and four areas of quantitative evaluation and nine detailed items were set as independent variables. Statistical analysis methods were T-test, ANOVA, and Regreesion. As a result of the analysis, it was found that there was a significant difference in the average of the evaluation group according to the affiliated organization and size. In addition, the factors affecting the number of visitors to public libraries were analyzed and presented. Implications were derived based on the analysis results, and can be used as a basis for establishing public library policies in the future.

We have cloned a ${\alpha}-COP$ homolog, ancop, from Aspergillus nidulans by colony hybridization of chromosome specific library using ${\alpha}-COP$ homologous fragment as a probe. The probe DNA was amplified with degenerated primers designed by comparison of conserved region of the amino acid sequences of Saccharomyces cerevisiae ${\alpha}-COP$, Homo sapiens HEP-COP, and Drosophila melanogaster ${\alpha}-COP$. Full length cDNA clone was also amplified by RT-PCR. Comparison of genomic DNA sequence with cDNA sequence obtained by RT-PCR revealed 7 introns. Amino acid sequence similarity search of the anCop with other ${\alpha}-COPs$ gave an overall identity of 52% with S. cerevisiae, 47% with human and bovine, 45% with Drosophila and Arabidopsis. In upstream region from the transcription start site, a putative TATA and CAAT motif were also identified.
