The goal of this study is to analyze the feasibility of establishment of the collaborative repository for public libraries in Korea. To that end, its feasibilities were analyzed from the sides of the relevant laws, national policy, library's recognition, and actual collection space. As a result, the feasibility of establishment of the collaborative repository was revealed by enough. Accordingly, based on the this basic research, there is a need to develop immediately the construction and operation model of the collaborative repository. And the Ministry of Culture, Sports and Tourism, and metropolitan city and province must grant priority of cultural policy in the establishment of the collaborative repository.

The purpose of this paper is to research and suggest ideal environment for the preservation of the National library collections. Current conditions of National library was also investigated, and many results showed that not only technical resolutions but also reorganization of staffs and structure is needed. Moreover, for the realization of ideal preservation environment, mid-long term development plans for the National Library was also provided.

Efforts to establish a joint preservation facility for library materials are being discussed in the regional representative libraries recently, but this is mainly a movement in public libraries. This study aimed to provide a model for a joint preservation facility construction and management especially for the National Universities Library in Busan/Gyeongnam area. For this job, after analyzing the current situation, this study focuses on 1) estimated size of the planned facility calculated by investigating the size and equipment, operation policy, collection quantity and saturation status of participating library archives, 2) strategies for construction, proposed a joint preservation architecture construction management model such as organization and human resources, and standards for transferring materials.

This study analyzes the relevance of retention period assigned for each unit task based on the table of records management standards that has been used in schools around the country since January 2011. Retention period, which used to be appropriated on the basis of a record file in the classification scheme, has been re-appropriated on the basis of unit tasks after the table of records management standards have been introduced. However, the new retention period of school records directly apply the 7 retention periods defined for public institutions according to Public Records Management Act. Therefore, this study attempts to analyze the relevance of retention period for school records appropriated for unit task from various angles regarding laws, indexes, survey results, overseas cases.

The Retained documents disposal project, promoted in 1968 and 1975, was executed as part of administrative plans for prompt movement of the government in case of national emergency. It was main contents that archival documents were re-appraised and reduced the least, and then moved rearward. The Retained documents disposal project denied The Records Management System of Korean Government that had been founded in 1964, promoted reduction of documents physically for convenience to dispersion of the government. Korean Government had completed these projects and then reorganized records management system to reduce creation of archival documents systematically in 1979.

본 연구는 돼지 액상정액을 인공수정용 100ml 플라스틱 병에 보존하면서 BF5희석액과 Butschwiler 희석액 간에 보존 온도별 차이를 조사하고, BF5 희석액에서의 글리세롤 농도의 효과를 조사하여 돼지 액상정액을 좀더 장기간 사용할 수 있는 방법을 찾고자 실시하였다. 돼지 액상정액을 5$^{\circ}C$ 냉장고에 보존하면서 조사한 바에 의하면, 37$^{\circ}C$에서 0.5 및 2시간 배양후의 정자운동성은 전체 보존기간동안 BF5 희석액이 Butschwiler 희석액보다 유의하게 (P<0.05) 높게 나타났고, 정상첨체비율은 두 희석액간에 차이가 없었다. 돼지 액상정액을 15$^{\circ}C$에 보존하면서 조사한 바에 의하면, 3일부터 7일 보존시 까지 정자운동성과 정상첨체비율에 있어서 Butschwiler 희석액이 BF5 희석액보다 유의하데 높게 나타났다. BF5 희석액을 이용한 돼지 액상정액의 글리세롤 농도의 효과에 있어서는 최종 글리세롤 농도가 0, 2, 3, 및 5% 보다 1%일 때 가장 높은 정자운동성과 정상첨체비율을 나타내었다. 분만율, 복당 생존자돈수 그리고 출생시 평균 생시체중은 BF5 희석애과 Butschwiler 희석액간에 차이가 없었다. 이상의 연구 결과를 종합해 볼 때 BF5 희석액을 5$^{\circ}C$에서 Butschwiler 희석액은 15$^{\circ}C$에서 6-7일 동안 돼지 액상정액을 보존할 수 있었다.

The purpose of this study is to present some basic information essential for planning long-term preservation of digital audio files, which have been collected through 'Cultural Archetypes Digitization Project' by the Korea Culture & Content Agency. Needs and limitations of digitization of audio resources for their long-term preservation, digital audio archiving models(OAIS Reference Model and AHDS Model), some technical principles for audio digitization and preservation, preservation metadata and storing media for digital audio files were discussed. Compliance to the requisites listed in Audit Checklist for the Certification of Trusted Digital Repositories of RLG & NARA was suggested. It was also recommended to review the appropriateness of collaborating on digital preservation project with other institutions.

In this paper we explain the definition and component of electronic records, and reestablish the principle of the preservation. Also we discuss the conceptual approaches and requirements for long-term preservation in an electronic environment. The preservation in digital environment is to protect itself of record identity with the reliability and authenticity, and to ensure the accessibility of records. It needs to be periodical migration along with digital environment change for the long-term preservation of the electronic records. and to select software independent standard format. to ensure the integrity of electronic records along with this preservation strategy, process and relative information required for digital preservation are to record in the form of metadata. The preservation system is separated into four functional entities ; registration process, preservation process, access process, main record management system. Also, this article is conceptually to introduce the selection criteria of storage media, the security provision for the archive collections and the disaster recovery which apply to the digital archives.

The effects of grapefruit seed extract and $H_2O_2$ disinfectants on Pseudomonas aeruginosa were investigated by antimicrobial assay and scanning electron microscopy. Pseudomonas aeruginosa is a Gram negative bacteria and a common causative microorganism of bacterial keratitis. After incubation of soft contact lens in Pseudomonas aeruginosa suspension for 120 minutes containing the disinfectants, the grapefruit seed extract showed antimicrobial activity as good as the chemical disinfectant. The living rates of Pseudomonas aeruginosa in grapefruit seed extract and $H_2O_2$ disinfectants were $1{\times10^3CFU/m{\ell}$ and $0.5{\times}10^3CFU/m{\ell}$, respectively showing no major difference in the killing activity. However, the mechanisms of the antimicrobial activity were quite different as indicated by scanning electron microscopy of the bacterial surface morphology. Considering chemically or other toxins induced keratitis, the natural disinfectant isolated from grapefruit seed extract shows promising results as a soft contact lens disinfectant.

The effects of R products of B company and natural disinfectant naringin, well-known chemical disinfectant on Corneal endothelium and epithelium of rabbit were observed by scanning electron microscope. The main component of naringin is extract of grapefruit seed, which is one of the flavonoid widely recognized as natural antioxidants and used as preservative agent of food and cosmetics. The chemical disinfectants cytotoxicity in cell cultures were announced by MIT assay and LDH leakage assay. But there has been no study about that chemical disinfectants and natural disinfectants is inserted drops on rabbit's cornea directly. In this test R products B company and natural disinfectants has been dropped on the cornea of rabbits for one weeks and observed cytotoxiciy by light camera after rose bengal staining. Also, we analysed the damage of corneal epithelium and endothelium morphologically after enucleating the cornea by scanning electron microscope.
