This study examines how CIP program of the Library of Congress distributes, provides an access to, and helps upgrade CIP data through bibliographic utilities. LC CIP program can be characterized by the participation of many U.S. mainstream publishers, a continuing increase in the number of CIP data assigned annually, and an effort to immediately upgrade the completeness and accuracy of CIP data in cooperation with bibliographic utilities. Cooperation between LC and bibliographic utilities in performing quality control is worth noting, when compared with the limitation of CIP program of the National Library of Korea. It is suggested that the National Library of Korea should provide complete and accurate bibliographic and authority records for other types of new and old library materials published in Korea as well as CIP data for new monographic materials.

LCSH is now used as a major subject access tool in library catalogs and national bibliographies. Internationally, LCSH has also gained wide acceptance. Over the years, many libraries in other countries have adopted or adapted LCSH. The purpose of this study is to analyze the historical process and characteristics of subject headings related to Korea in the LCSH, from the first edition to 30th ed. The analytic results show that the section of Korean history and related subject headings are different from the terms used in Korean academic world : Some subject headings considered important and essential are left out. We can also recognize the some headings are relatively too subdivided. The omitted and insufficient Korean subject headings are considered to be tied up with library policies of LC. Therefore our active support such as donation are being called for collecting more detailed analysis of Korea-related publications in LC.

In this paper, typical types of digital format were defined and digital format selection guidelines of US's NISO(National Information Standards Organization) and LC(Library of Congress) and Denmark's The State and University Library and the Royal Library were introduced. Five sustainability factors and quality and functionality factors were raised through analysing the three sample guidelines. The sustainability factors include descriptive, independency, consistency, widely adopted, and quality. Thus, digital format selection strategies for a library were developed.

The purpose of this study is to analyze the historical process and characteristics of subject headings related to Korea, China, Japan in the LCSH, from the first edition to 31th ed. The analytic results show that the headings in the 31th edition include in Korea 713, China 1,742, Japan 2,647, compared to Korea headings 4, China headings 49, Japan headings 24 in the first edition. Some subject headings considered important and essential are left out. We can also recognize the some headings are relatively too subdivided. The omitted and insufficient Korean, Chinese, Japanese subject headings are considered to be tied up with library policies of LC. Therefore our active support such as donation are being called for collecting more detailed analysis of Korea, China, Japan-related publications in LC.

The purpose of this study is to understand the direction of the community reading campaign in the U.S.A. known as 'One Book, One City' reflected in the books selected for this campaign for the past 20 years in terms of their classification numbers, subject headings, publication dates, and genres. Analyzed are the author and state lists of 'One Book, One City' Reading Promotions Projects available from the website of the LC (Library of Congress) Center for the Books, and bibliographic records of 735 books selected in only one 'One Book' program, accessed from LC OPAC. Major findings include continuing influences of the all-time favorite 'One Book' selections, including To Kill a Mockingbird and the extension of their span of life through The Big Read, preference for the recent publications, importance of P (Literatures and Languages) Class (530 titles, 72.1%) and PS(American Literatures) subclass (307 titles, 57.9%) in the LC Classification Scheme, distribution of books in 43 genres, including domestic fiction, historical fiction, and psychological fiction, etc., the use of 535 unique LC subject headings and much interests in "City and town life" (10 titles) and "World War, 1939-1945" (8 titles), and prominence of subject groups which begin with "African American..." and "Woman..." out of 96 groups of subject headings. It is found that the subjects and focus of the selected books expand from integration, understanding, integrity to human rights, environment, peace, etc. The limitations of this study is that the influence of the selected books and the changes in communities are not properly analyed.

Yeast surface-displayed antibody libraries provide an efficient and quantitative screening resource for given antigens, but suffer from typically modest library sizes owing to low yeast transformation efficiency. Yeast mating is an attractive method for overcoming the limit of yeast transformation to construct a large, combinatorial antibody library, but the optimal conditions have not been reported. Here, we report a large synthetic human Fab (antigen binding fragment) yeast surface-displayed library generated by stepwise optimization of yeast mating conditions. We first constructed HC (heavy chain) and LC (light chain) libraries, where all of the six CDRs (complementarity-determining regions) of the variable domains were diversified mimicking the human germline antibody repertoires by degenerate codons, onto single frameworks of VH3-23 and $V{\kappa}1$-16 germline sequences, in two haploid cells of opposite mating types. Yeast mating conditions were optimized in the order of cell density, media pH, and cell growth phase, yielding a mating efficiency of ~58% between the two haploid cells carrying HC and LC libraries. We constructed two combinatorial Fab libraries with CDR-H3 of 9 or 11 residues in length with colony diversities of more than $10^9$ by one round of yeast mating between the two haploid HC and LC libraries, with modest diversity sizes of ${\sim}10^7$. The synthetic human Fab yeast-displayed libraries exhibited relative amino acid compositions in each position of the six CDRs that were very similar to those of the designed repertoires, suggesting that they are a promising source for human Fab antibody screening.

The purpose of this study is to analyze the characteristics of OPAC displays of the National Library of Korea and the Library of Congress. based on the 'OPAC Display Guidelines(Draft)' published by IFLA. Discussed are such topics as a basic search process and the headings list, a brief display and the arrangement of bibliographic records, a brief record and a full record, use of terms and labels. link between records, and organization of screens for the OPAC display. It is strongly suggested that when compared with the LC's OPAC, the OPAC display of the National Library of Korea should be much improved by following the recommendations of the 'OPAC Display Guidelines(Draft)'.

This study intends to make a comprehensive inquiry into the quality of subject data in library catalogs. On the basis of National Library Subject Headings (NLSH) developed in 2002, National Library of Korea (NLK) has input the subject data into cataloging records since 2003. However a serious question could arise regarding whether the data are appropriate and desirable as a subject of the work. Under these circumstances, this study examined as follows: First, the meanings and attributes of the 'subject' were examined with a comprehensive literature survey. Second, a experimental analysis was carried out to measure the quality of the subject data. Sample records were selected from NLK, LC and A university library in Korea, and absolute and relative quality were compared. Finally, the substantial and realistic strategies for improving the quality of subject data were discussed.

The single-stranded large circular (LC)-sense DNA were utilized as probes for DNA chip experiments. The microarray experiment using LC-sense DNA probes found differentially expressed genes in A549 cells as compared to WI38VA13 cells, and microarray data were well-correlated with data acquired from quantitative real-time RT-PCR. A 5K LC-sense DNA microarray was prepared, and the repeated experiments and dye swap test showed consistent expression patterns. Subsequent functional analysis using LC-antisense library of overexpressed genes identified several genes involved in A549 cell growth. These experiments demonstrated proper feature of LC-sense molecules as probe DNA for microarray and the potential utility of the combination of LC-sense microarray and antisense libraries for an effective functional validation of genes.
