The books and circulation-related data in the Library Automation System(LAS) of C-academic library were collected and analyzed, and also the method which may be applied to the Customer Relationship Management (CRM) based on the results was suggested in this paper. Collected data were 269,387 bibliographic data of books, 12,281 patron data, and 39,269 circulation records. User identity, circulation frequencies, total number of circulated books, and publication year as relation factor from the analyzed data of circulation records were extracted. They were also analyzed, and verified by correlation coefficient.

The yeast surface-displayed cDNA library has been used to identify unknown antigens. However, when unknown target antigens show moderate-to-low abundance, some modifications are needed in the screening process. In this study, a directional random-primed cDNA library was used to increase the number of candidates for the unknown antigen. To avoid the loss of target yeast clones that express proteins at a low frequency in the cDNA library, a comprehensive monitoring system based on magnetic-activated cell sorting, fluorescence-activated cell sorting, and immunofluorescence was established, and a small number of target yeast cells was successfully enriched. These results showed that our optimized method has potential application for identifying rare unknown antigens of the human monoclonal antibody.

These experiments were carried out to construct mouse testis cDNA library and to to seen H-Y Ag gene. Mouse testis was obtained from BALB/c inbreed mouse that was after-born 1 week. Isolation of mouse testis total RNA was carried out by guanidum/cesium choloride, poly(A+) mRNAs were purified by oligo d(T)-cellulose chromatography method. To investigate protein synthesis activity, in-vitro translation carried out by total RNA and poly(A+) mRNA. The products of in-vitro translation were identified in 12.5% PAGE. Single strand DNA and double strand DNA were synthesized from poly(A+) mRNA and purified using phenol/chloroform/isoamylalcohol. Synthesized cDNA was combined with cohesive Eco RI polylinker, its recombination efficiencies were identified by X-gal and IPTG. In the cDNA library, 1$\times$107 phagemids were screened with 32P labelled probe. Hybridization were carried on $65^{\circ}C$ for 16~20hours. And 1$\times$106 phagemids were screened with rabbit-anti-H-Y. In former, select 5 positive clones, and later, 1 positive clone. Its southern blot analysis showed various size of insert cDNA from 0.7kb to 3kb.

This study has examined the cause of the library anxiety among foreign students upon visiting college libraries. 131 students were investigated using Library Anxiety Scale (LAS) to analyze the relationship between sex, grade, library use education, frequency of library use, Korean skill and cultural heterogeneity. The result of the LAS showed an average of 2.60 among foreign students, and the anxiety from the "mechanical barrier" was scored the highest. For sex, male students tended to be relatively more anxious than female students on the "accommodation of library" and "knowledge of library." Students who participated in the library use education were less anxious than those who did not, and the more one used library, the less one became anxious. Based on these results, the study proposes the way ahead for resolving library anxiety through library use education and frequency of use.

This paper examines the ways of using information resources available through information retrieval systems of portal sites. We analyze the types of information resources, search capabilities, and interfaces of Naver, Empas, and Google Scholar. Naver's retrieval system sells research reports, papers, patents information, etc. to users, which is similar to C2C(Customer to Customer in e-commerce environment). Empas provides information from journals, research reports, and proceedings with no charge. Google Scholar's noteworthy efforts are their collaborative programs with and/or for major U.S. libraries, such as "Library Link" and "Library Project." Considering the extended information retrieval services of portals, especially the services like Google Scholar's library programs, libraries need to develop more specialized services, such as the customized information service for individual user, development of user convenience tools like OCLC WorldCat, more accessibility through ubiquitous library concept, and collaboration among libraries.

For a public library. which is a regional information service agency. to acquire high competitiveness, preparation for uncertainties of future through understanding its own internal strengths and weaknesses. and external opportunities and threats based on assessments regarding knowledge information environment and characteristics of regional community. current status of the library, etc. Therefore. in this study, through SWOT analysis. one of competitive strategy analysis methods, the status of competitive strategy of C library was analyzed. In order to carry out the study interview and survey were performed with professional librarians, then through final consultations from management consulting experts, a plan to strengthen competitiveness for C library was devised. Conclusions from this study were as below. In order to strengthen competitiveness of C library offering distinguished high quality services through active cooperations with external institutions, efforts to improve library's position and stand following being selected as a library to visit for 2006 World Library and Information Congress, and revitalization of library usage through providing user oriented differentiated services are needed.

This study has been conducted to building a library intended for structures considered in the design of reclamation for design automation and developing browser for integrated management system. The library has been developed using a parametric modeling method capable of changing section shape, also classifying standard crossing and family library, has been developed according to the working environment. Classified library by the characteristics manages objects and working modeling on based BIM has been developed browser using the C# program for objects to use conveniently. By interworking between developed Browser and 3D Autocad based BIM, it is possible to use easily at design drafting, calculating quantities, developing a new library, and managing a library. The browser using effectively exclusive library to reclamation is developed in this study.

A subtracted cDNA library specific to osmotic stress of Haloxylon ammodendron (Mey.) Bge seedlings was constructed by suppression subtractive hybridization (SSH) and T/A cloning. SSH was performed between two groups of H. ammodendron seedlings, one was cultivated in Hoagland (H) solution as a driver and the other group was treated with osmotic stress of the Hoagland solution by the addition of 400 mM mannitol (M), as a tester. The library consisted of about 400 recombinant clones, with the average size being of 500 bp, ranging from 300 bp to 1500 bp. Using a PCR-select differential screening kit, 100 recombinant clones were randomly chosen from the subtracted cDNA library and hybridized with forward,reverse subtracted and unsubtracted probes for two rounds. As a result, 21 positive clones specific to osmotic stress were obtained and some of them were verified by Northern blot analysis. The sequencing analysis of 6 positive clones and the following homology comparison to GenBank [blastx] non-redundant databases characterized that two sequences obtained in this experiment may contribute to novel drought-related genes.

In this paper, we propose a method of class library repository design for provide reuser the object-oriented C++ class component. To class library design, we started by studying the characteristics of a reusable component. We formally defined the reusable component model using an entity relationship model. This formal definition has been directly used as the database schema for storing the reusable component in a repository. The reusable class library may be considered a knowledge base for software reuse. Thus, we used that Enumerative classification of breakdown of knowledge based. And another used classification is clustering of based on class similarity. The class similarity composes member function similarity and member data similarity. Finally, we have designed class library for hierarchical inheritance mechanism of object-oriented concept Generalization, Specialization and Aggregation.
