In this study, we aimed to examine the feasibility of establishing a shared preservation center with a focus on the Chungcheongbuk-do Office of Education. We conducted surveys to assess the current situation and gather perceptions. The research findings revealed the following: Firstly, the surveyed school libraries were already experiencing extreme levels of book saturation, necessitating the management of book saturation and proper book quantity. Secondly, very few libraries had the facilities required for book preservation. Thirdly, the research showed that in 78% of school libraries, book saturation already exceeded 75%, leading to a rapid increase in discarded books each year. Therefore, there is an urgent need for the systematic expansion of a shared preservation center. Moreover, given the difficulty of individual libraries in establishing facilities for preservation, valuable materials such as rare books and specialized resources should be transferred to a shared preservation center. Additionally, policies and regulations related to material preservation are deemed necessary.

This study aims to explore ways to improve self-censorship tendency in teacher librarians by identifying factors that influence the self-censorship which appears during collection development in elementary school libraries. For this purpose, first, we examined the concept of self-censorship through a review of related literature, then carried out a series of in-depth interviews as a pilot study to develop a questionnaire, which was used for a questionnaire survey. Finally, the survey data was analyzed statistically with SPSS 21.0, a statistical package. As a result, we have discovered statistically significant relationships between self-censorship and the characteristics in collection development policies, school library committees, and the complaints related with the library collections. Based on these results, the factors on the self-censorship were identified in the perception of the school librarians. Based on these results, we suggest to reinforce the function of review and approval of book selection in the school library committee, developed and approved a collection development policy include guidelines for dealing with users' complaints related to library collection, and stipulated a regulation for school library operation to remove inappropriate books from the library collection.

Due to the rapid growth of publications, librarians have been facing the problems caused by the shortage of stack as well as the quality deterioration of library collections. This naturally disappointed the user communities and the present library activities are weak and inadequate. It seems to the author that one of the desirable actions in remedying this problems is to weed library collections properly and regulraly. The purpose of this study is to establish weeding criteria in library collections, particulary in the fields of polictical science, economics and law In order to establish weeding criteria, shelf-time period which is the length of time that a book remains on the shelf between the last two users of a volume, was measured by examining the book cards or date-due slips of circulating books and collections which remained in the stack. The results of this study are as follows: (1) In the fields of political science economics and law, the shelf-time periods of general materials in Korean for circulation was measured. (2) This study shows shelf-time periods that vary in different subject fields. (3) Combining the shelf-time periods of books in active circulation and the total collection including books which have never been circulated, the size of library holdings which may satisfy a certain percentage of the current circulation can be estimated.

This study focuses on how public libraries in East Germany adjusted themselves into new environments after the unification during 15 years(1990~2005). First, system and operation of East Germany's public libraries are studied and public libraries in West and East Germany are compared before the unification. After public libraries in East Germany became unified with West Germany, the structure of East Germany's public libraries changed, many of public libraries and labor libraries were closed and collection in those libraries was discarded or replaced. Thus, it is studied how libraries enhanced their capabilities and discovered their roles or identities in changing situations in this research.

Today, one of the major pressures that libraries have been facing is the rapid growth of publications. Due to the rapid growth of publications, libraries have been faced the shortage of stack as well as quality deterioration of library collections. Naturally, these disa n.0, ppointed the users and made the present library activities weak and inadequate. One of the desirable actions in remedying these problems is to weed library collections properly and regularly. Weeding methods used in libraries are derived from the judgement by subject specialists, from the examining the imprint date and the past use patterns of a volume. Among these methods, the past use patterns are highly predictive of the future use, and can be used to create meaningful weeding criteria. Since the libraries in Korea have emphasized on numbers of library collection in the past, the libraries have neglected weeding library collections. Now, we must turn our concern toward the weeding library collections, and the attitude of the library services to the users must change from passive to active.

This study was to suggest the problems and the improvement plan of Digital Library System (DLS) which has solved the library management and has supported the data building for resource sharing in school libraries since 2001. The 9 DLS committees were interviewed about the current situation of DLS use and the problems of DLS system in the 6 areas of acquisition, cataloging, circulation and discharge, inventory, library statistics, and searching interface as the research methods. Based on the interviews, the improvement plans were suggested as followed. In acquisition, it was to need the acquisition system development and online purchase for users. In cataloging, the improvement of data quality management, and indexes and vocabularies control for upgrade of searching function were needed. The advanced circulation speed in circulation, the restoration of discarded data in inventory and the exact statistic data in library statistics were need to improve the DLS. This study would contribute to the betterment of DLS and increase the use of DLS.

The purpose of this study is to analysis the type of cited materials, dependence ratio of foreign information of domestic researchers, and to predicts half-life of life science for the collection development of libraries and user friendly information services. The journal articles was extracted from five subjects-medical science, pharmacy, food science, agricultural science, microbiology. In result, it was found that it citing the scholarly journal most plentifully, and dependence ratio of foreign information of domestic researchers was high most the microbiology. And then, half-life of life science was found 8.98 in agricultural science, and 7.11 in food science, and 6.96 in pharmacy, and so on.

Recently, it has been important issue to recycle the rapid increase of construction waste. The site-recycling of construction waste has been one of alternatives to recycle construction waste. The economic superiority of site-recycling was shown in previous studies, but it is hardly studied in the Quantification of social costs from site-recycling. This study identified the generation of the carbon dioxide from the site-recycling and Quantified the social costs of it. Also, this study performed the comparison and analysis of the social costs of the carbon dioxide in accordance with the aggregate production from the site-recycling, processing on commission, and a stony mountain. The results of this study indicated that the site-recycling was the most effective in the social costs.

Yuza (Citrus junos Sieb ex TANAKA) is a citrus fruit that is cultivated in northeast Asia. Citron is known for containing abundant antioxidants such as vitamin C, flavonoids, for example hesperidin and hesperetin, and terpenoids such as limononin. When mature citron is processed for tea or other beverage food products in Korea, massive amounts of seeds and pericarp are remained as waste. This study aimed to exploit the processed remnant of Citron for developing functional cosmetic applications. Ethanol extracts of Yuza seed and pericarp did not show significant radical scavenging activities measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) method. But they contained significantly high phenolic compounds. Cultured human dermal fibroblasts and HaCaT keratinocytes were irradiated with 25 mJ UVB and the citron extracts were added to the medium of each culture. Cellular damages caused by UVB irradiation were prevented by the addition of the Yuza extract. In addition, the reduction of the enhanced MMP-1 expression after irradiation of UVB in human dermal fibroblasts was observed. Also the increased level of pro-inflammtory TNF-$\alpha$ in the UVB irradiated HaCaT cells was decreased. The collagen expression was enhanced by the extract. Yuza extract markedly inhibited melanin production from $\alpha$-MSH treated B16F1 melanoma cells. Melanin assay, tyrosinase zymography results indicated that Yuza extract had strong depigmenting activity. In conclusion, Yuza ethanol extracts have good anti-photoaging and strong anti-melanogenic efficacies.
