Digital preservation becomes, nowadays, one of the important business process in the academic libraries. This study is to investigate the librarians' perception on digital preservation requirements and to analyze the business practices of the digital preservation and digital preservation level in the 102 academic libraries. In results, it is found that the digital preservation specialists in academic libraries have almost same perception on basic policies and direction. Also, the study finds that the important function of digital preservation is to secure authenticity and integrity; policy and expertise are the most important key components for digital preservation; the most frequently reported barriers to preservation are the lack of willingness and funding problems; most librarians want to learn and train how to establish preservation planning and policy. In general, most librarian think that the level of digital preservation in the academic libraries is insufficiency. Therefore the academic libraries should establish the relevant digital preservation policy and business workflows and to develop capacity of digital preservation.

The objective of digital preservation is to ensure that digital information survives in usable form for as long as it is wanted That is to ensure long-term access to digitally stored information. The preservation of digital objects involves a variety of challenges, including policy questions, institutional roles, legal and rights issues, metadata, and technical strategies. In this paper, I introduce the definition of digital object life-cycle of digital object and related archiving workflow which are basic concepts of digital archiving. Also I focus on the aspects of current techniques used in digital information preservation including technology preservation, emulation, refreshing, migration, encapsulation.

The preservation metadata which is defined the property and history of changes must be describes logically and structurally for implementing long-term digital preservation. The preservation metadata makes the users to access and retrieve authentic digital resources and the managers of digital archives to manage and preserve more effectively the digital resources. his paper is review of recent developments relating to digital preservation metadata including the taxonomy of information object classes of Reference Model of OAIS and outlines some library-based projects. Next, the paper investigates how to develop and use the preservation metadata in university libraries and what is the core preservation metadata elements. Finally, the paper recommends the set of preservation metadata elements with broad applicability to digital preservation in university libraries.

To guarantee the long-term access to digital material, digital preservation needs to be systemized, and detailed investigation on cost elements of digital preservation should be done for the continued support of budget. To meet the needs in this area, this paper categorized the digital preservation cost into direct and indirect cost through deriving common elements used in prior research on this issue. For case analysis, two institutions, representing domestic University Library and National Library of Korea under large-scale digitization currently, are selected to analyze the current status of digital preservation and estimate the preservation cost. The case analysis shows the systematic preservation function should be performed to guarantee the long-term access digital material, even though a basic digital preservation is currently conducted. It was projected that the digital preservation cost for the two libraries, accounting for $11.8\%$ and $8.6\%$ of digitization cost, respectively, should be injected every year. However, the estimated figures are very conservative, because the cost for estimating the preservation function, such as installing digital repository and producing meta data, was excluded in the estimation. This proves that digital preservation is a synthetic activity linked directly and indirectly to various activities from production to access of digital object and an essential costs that should be considered from the beginning stage of digitization project.

현재의 고도 디지털 정보화 사회에서는 많은 자료들이 디지털로 생산, 관리, 이용, 보존되고 있으며 이들의 안전한 장기보존은 역사의 연속성 측면에서 매우 중요한 문제이다. 공공기관, 민간기업 등 대규모 조직에서는 조직의 연속성을 보장하기 위해 이런 디지털자료의 보관을 위해 많은 노력을 기울이고 있으나 개인의 디지털 자료는 영속성 있게 보관하기가 매우 어렵다. 이 논문에서는 개인이 소유한 디지털 유산도 안전하게 장기보존될 수 있어야 한다는 필요성을 제시하고 이를 위해 필요한 정책적, 기술적 방안들에 대해 검토해 보고자 한다.

The study identifies benefits arising from the digital preservation of research data. Through analysing studies on digital preservation and digital research data in a economic perspective, broad benefits from digital preservation of research data have been identified and analysed quantitatively as well as qualitatively. It provides the starting point of systematic management and preservation of digital research data. Furthermore, it attempts modelling for investigating and producing benefits both in quantity and quality that is fundamental to promote investments.

Digital information resource requires detailed metadata to ensure its long-term preservation and accessibility for future generations. This paper illuminated the characteristics of digital information resources, the concept of digital preservation and the necessity of metadata for long-term preservation of digital information resources. And this paper examined the 16 elements of RLG metadata for preserving digital information and the Reference Model for an Open Archival Information System(OATS) to support the interoperability of digital archiving. And then this study investigated concretely element sets of the preservation metadata for digital information resources in the Cedars and OCLC/RLG embodied within the OAIS framework. As result of the study, the paper suggested basic plan required to provide preservation metadata elements to preserve digital information resources in Korea.

The construction of preservation metadata is a prerequisite for the preservation of digital information. In the current approaches to digital archiving, however, there is no metadata structure optimized to describe preserved digital objects. This research proposed metadata packages that can support the description of digital objects from the perspective of the core processes of digital archiving. The proposed metadata packages consist of 4 wrapper elements and 25 sub-elements. They can provide detailed descriptions required to preserve digital objects in accordance with the core processes of digital archiving. Therefore, the proposed metadata package can be applied to digital archiving as a better approach to the description of digital objects compared to the approaches to information package.

University libraries have developed digital information resources for digital services and have tried to preserve valuable digital information. Because digital preservation raises challenges of a fundamentally different nature which we added to the problems to preserving traditional format materials, it is necessary that preserving digital resources must be discussed and researched actively. This study conducts risk management for exploring preserving technologies and assessing tools. It is found that most university libraries have used format conversion frequently and do not use the emulation technology. It is also found that medium refreshing has the lowest risk probability and isk impact, but information migration and emulation technology have the highest in the risk probability and in the risk impact individually and the absence of full-time professional staff causes high risk.

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.
