The paste used for conserving and mounting has much to do with the life of cultural properties of paintings. Previous studies on the pastes dealt with elimination of protein from wheat flour as protein has been known to do harm to paste and investigated the effects of starch and protein content on adhesive strength and conservativeness. We found that protein content inversely affected adhesive strength while adhesive strength and viscosity of paste were proportionally related to starch concentration of the paste. The adhesives with more protein showed less conservativeness. Types and number of microorganisms were found to increase as protein percentage increased. All these results points that the higher content of protein in adhesive formula support higher microbial growth with reduced adhesive strength, but higher flexibility. The optimized paste of conservation treatment was wheat starch paste with not only minimize viscosity but also maximized adhesive strength.

Paper relics, which are made of natural ingredients, are more likely to be damaged by a compendium of complicated causes (e.g., physical, chemical, and biological causes) rather than by a sole cause. In December 2009, Culture Heritage Conservation Science Center discovered several damages in paper relics related to Chungmugong Yi Sunsin, and requested for conservation treatment from the Hyeonchungsa Shrine office. By conducting a comprehensive research to determine the damage level of each artifact, the center was able to establish a proper conservation method, and for two years after its completion of such research in 2010, it has been conducting treatment. This study suggests the proper ways to select adequate conservation treatment based on the type of paper relics - Documents and Books - through the case of artifacts related to Chungmugong Yi, Sunsin. Even though the conservation treatment on paper relics can suppress damaging speed and prevent another damages, it is impossible to stop aging process of relics. Therefore regular inspection is essential for prevent second damage.

Deterioration and brittleness of resources on the shelves of institutions such as libraries and archives have been increased and accelerated as time passes in accordance with the preservation environment and the nature of their own material. It can be a loss of current information with little importance in prolong the life of valuable materials and to preserve them in security, integrated preservation programs should be developed and implemented according to missions, sizes, the nature of collections, users, and budgets of individual institutions. In reality, most institutions, however, are not able to implement perfect preservation programs due to lack of budget, human resources, and expertise. To solve this problem, some institutions in similar circumstances have planned cooperative preservation programs in various levels. Through cooperative systems individual institutions can not only pursue common interests but gain real benefits for themselves. Consequently institutions are recommended to collaborate with in development and implementation of various preservation programs at local, national, and international levels in addition to individual institutional programs.

The purpose of this study is to explore the establishment and administrative strategies for shared repositories for academic libraries in Korea, using the US ReCAP (Research Collections and Preservation Consortium) Project as a case study. The US ReCAP Project was a collaboration between the New York Public Library and the university libraries of Columbia University, Harvard University, and Princeton University. In-depth interviews were conducted with librarians and administrators in charge of the ReCAP Project to understand the original vision of the project, as well as how the strategy and approach evolved over the years. The analysis results revealed that shared repositories for libraries have evolved into shared collections enabling shared use. But shared repositories require a central management system to be successful in the long-term. Additionally, findings showed that the shared repository filled more quickly than anticipated. This in turn required collaborative planning on shared collection development and selection policies to determine which materials to send to the shared repository.

The 3rd Library Development Plan raises the need to secure space through the establishment of a regional repository library as the issue of holding books is highlighted as a common problem in public libraries. The Korean Library Law Act also impose the responsibility of integrated management of local library materials on the regional representative library. Accordingly, this study aimed at Busan Metropolitan Library, which is operating a collaborative repository in earnest among regional representative libraries, and investigated the operation status of the collaborative repository and the perception of public librarians about the collaborative repository. The data necessary for the study were obtained through surveys, interviews, field surveys, and internal data analysis. Through this, the purpose of this study was to provide basic data that will help the Busan Metropolitan Library to operate the collaborative repository efficiently in the future, and at the same time, to present basic data that can be used as a reference for the operation of the collaborative repository of the representative libraries of other regions.

In the electronic records environment, along with discussions on ways to digitize analog records, it is important to prepare preservation strategies for each type of records produced and received electronically. In the same context, there is a need for discussion on applying a preservation format selection system with the goal of long-term preservation of data sets and audio-visual type electronic records other than document types. Audiovisual records must apply preservation strategies appropriate to the characteristics of each medium, such as images, audio, and video. This study establishes unique standards for selecting a preservation format for audio-visual electronic records through analysis of Significant Properties based on literature review, composed audio-type preservation format suitability evaluation items, and proposed a recommended format based on the results of applying them.

Due to its topographic complexities and various climatical condition, Korea exhibits diverse forest types. Dominant tree species in this zone are Quercus spp., Betula spp., Zelkova spp., Fraxinus spp., Pinus densiflora, Pinus koraiensis, and Pinus thunbergii ete. Genetic conservation in forest species in Korea there are three ways ; one is in situ, other is ex situ and third is in-facility conservation. In situ conservation include that are the present status of conservation of rare and endangered flora and ecosystem, the reserved forest, the national and provincial park, and the gene pool of natural forests. Ex situ conservation means to be established the new forest from in situ forest stands, progeny and provenance test populations, seed orchard and clone banks, and gene conservation in-facility. As a tool for low temperature storage, several aspects on in vitro system were studied ; (1) establishment of in vitro cultures from juvenile and/or rejuvenated tissues, (2) induction of multiple shoots from the individual micropropagules, (3) elongation of the proliferated shoots. Studies on cold storage for short-and long-term maintenance of in vitro cultures under $4^{\circ}C$ in the refrigerator were conducted. For the cryopreservation at $-196^{\circ}C$, various factors affecting survivability of the plant materials are being examined. The necessity of gene conservation of forest trees is enlarged not only to increase the adaptability for various environments but also to gain the breeding materials in the future. For effective gene conservation of forest trees, I would like to suggest followings ; 1. Forest stands reserved for other than the gene conservation purposes such as national parks should be investigated by botanical and gene-ecological studies for selecting bio-diversity and gene conservation stands. 2. Reserved forest for gene pool should be extented both economically important tree spp. and non-economical species. 3. Reserved forest for progeny test and clone bank should be systematically investigated for the use of Ex situ forest gene conservation. 4. We have to find out a new methodology of genetic analysis determining the proper and effective size of subpopulation for in situ gene conservation. 5. We should develop a new tree breeding systems for successful gene conservation and utilization of the genetic resources. 6. New method of in-facility gene conservation using advanced genetic engineering should be developed to save time and economic resources. 7. For the conservation of species with short-life span of seed or shortage of knowledge of seed physiology, tissue culture techniques will be played a great role for gene conservation of those species. 8. It is are very useful conservation not only of genes but of genotypes which were selected already by breeding program. 9. Institutional and administrative arrangements including legistlation must be necessarily taken for gene conservation of forest trees. 10. It is national problems for conservation of forest resources which have been rapidly destroyed because of degenerating environmental condition and of inexperienced management system of bio-diversity and gene conservation. 11. In order to international cooperation for exchanging data of bio-diversity and gene conservation, we should connect to international net works as soon as possible.

Regional representative libraries are installing joint preservation archives to solve the problem of lack of preservation space in libraries. This study conducted a survey of public library librarians through a questionnaire survey and an FGI method in order to prepare specific operational policies and implementation plans for the Chungnam Library Joint Preservation Archive, which is a regional representative library. Based on this, an operation policy and implementation plan suitable for the common preservation and use of printed and digital data, which is the goal of the Common Preservation Archive, was proposed. As a result of the study, first, the joint preservation library of the Chungnam Library should first transfer books and serials along with ownership in consideration of the condition and demand of the preservation space of participating libraries. Second, it is necessary to establish an operation management system that can be used by all participating libraries in order to quickly and conveniently operate the joint preservation data center and connect it with a cloud-based integrated data management system. Third, a plan for digitizing and archiving data that was judged to be digitized in the Common Preservation Archive was proposed.

배경: 이식폐의 보존 및 재관류 동안 cyclic adenosine monophosphate(cAMP)와 nitric oxide(NO)는 폐혈관 내 순환조절을 유지하는데 있어 중심적인 역할을 한다. 그러나 내치세포내의 cAMP와 NO 모두 허혈-재관류 과정 동안에 현저하게 감소한다. 이에 저자는 low potassium dextran(LPD) 폐조본액에 cAMP의 유사체인 dibutyry1 cAMP(db-cAMP)와 NO의 공여물질인 nitroglycerin(NTG)을 첨가하여 이들의 폐보존 효과를 알아보고, 이들은 첨가한 폐보존액 들의 효과를 비교하였다. 대상 및 방법: 토끼 폐장 분리관류 모형에 실험군은 각각 6마리씩 4개군으로 단순 LPD 페보존액만 사용한 경우(I군), LPD 용액에 NTG 만 참가한 경우(II군), cAMP 만 첨가한 겨우(III군) 그리고 두가지 모두를 첨가한 경우는 IV군으로 분류하였으며, 폐보존액이 주입된 심폐블록은 영상 1$0^{\circ}C$에서 24시간 동안 보관한 다음 100% 산소농도에서 기계호흡을 하면서 신선 정맥혈로 30분 동안 재관류를 시행하였다. 재관류폐의 평가를 위해 폐기능 및 폐부종 정도를 정량 측정하였으며, 유출로 혈액으로부터 tumor necrosis factor $\alpha$(TNF-$\alpha$)와 간접적인 NO의 총량을 알기 위해 nitrite/nitrate의 양을 측정하였다. 또한 재관류가 끝난 후 광학 및 전자현미경학적 소견을 관찰하였다. 결과: 모든 실험군 중 제 IV군 의 폐보존 능력이 가장 우수하였으나, 제 II, III, IV군 사이는 통RP적으로 유의한 차이가 없었다. 제 I군은 제 II, III, IV군들에 비해 유의하게 폐기능이 가장 나쁘고 폐부종 정도가 가장 심했다(p<0.05). 제 II군은 제 III군에 비해 더 좋은 폐기능을 보였고, 폐부종 정도가 덜 하였으나 통계적은 유의성은 없었다. TNF-$\alpha$ 는 제 IV 군이 Irns에 비해 유의하게 분비량이 적었다. (p<0.05). 총 NO의 양은 제 II군과 IV 군이 제 I 군과 III군보다 유의하게 높았으나(p<0.001), 제 II군과 IV군, 제 I군과 III군 사이 비교에서 유의한 차이는 없었다. 또한 제 I 군과 III군에서는 시간이 지남에 따라 유의하게 NO의 양이 점차 감소하였다. (p<0.05). 광학 및 전자현민경 소견상 폐포 및 폐혈관 구조가 제 II, III, IV 군이 I 군에 비해 더 잘 보존되어있었다. 결론: LPD 폐보존액에 db-cAMP 및 NTG의 첨가는 폐보존 효과가 모두 우수함을 확인하였고 이들의 폐보존 효과 차이는 거의 없음을 알수 있었다. 그렇지만 이들의 병합사용이 폐혈관 항상성을 더 잘 유지시킬 수 있고 허혈-재관류 손상을 줄여 폐보존 효과를 높일 수 있을 것이라고 기대된다.

As the use of information has emerged as the core of national competitiveness, major developed countries and the Korean government have realized the importance of data. They have pursued technical research and standard establishment for long-term preservation and continuously strived for systematic management and preservation of data. However, although various types of data are specified for the purpose of record management in the law, there is no specific method on how to collect, manage and preserve them, except standard electronic documents. In particular, management and preservation of huge datasets from the administrative information system have been strongly demanded above all. Any guidelines for datasets do not have been properly provided. After the framework for selecting preservation format must be prepared, the system can be supplemented and built. The framework considering the characteristics of the dataset should be specified more concretely, and empirical verification of the conversion and restoration for the dataset preservation format derived according to the selection criteria is necessary. Therefore, this study intends to propose a method for long-term preservation through empirical verification of the preservation format after deriving an evaluation the framework for the preservation format selection criteria considering the characteristics of the dataset.
