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.

중대사고관리 전략의 하나로서 피동형-설계에 적용되고 있는 용기내부보존(IVR)기념 - 이 논문에서는 실제적으로 원자로 압력용기벽 외부냉각(ERVC)방법을 사용한다 -이 규제측면에서는 용융물의 냉각가능성 쟁점의 해결이라는 문맥에서 조감되었다; 기술측면에서는 IVR개념의 신빙성 및 유융성이 언급되었다. 덧붙여서, 이 ERVC방법들이 개량형-설계에 적용되기 위하여 요구되는 점들이 규제측면과 기술측면에서 각각 검토되었다. 이 검토결과의 바탕위에서 용융물 냉각가능성/급냉가능성의 쟁점과 관련하여 전력연구원(KEPRI) 신형원전개발센타(CARD)에서 개발중인 한국차세대원전(KNGR)-설계에서 선택될 수 있는 대안적 전략들이 제안되었다: (1) 전략1A: 젖은공동방법의 신빙성에 기반을 두는 것; (2) 전략1B: 젖은공동방법/격납건물건전성에 기반을 두는 것; (3) 전략2A : ERVC방법의 신빙성에 기만을 두는 것, (4)전략2B: ERVC방법/격납 건물건전성의 균형된 접근법에 기반을 두는 것. 마지막으로, 신형-설계적용의 관점에서 각각 규제측면과 기술측면에서 본 현황파악 및 대책마련의 권고사항이 제시되었다.

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.

과학기술의 급진적인 발달과 환경보존규제 강화로 자동차의 수명도 그렇지만 항공기의 수명이 20년에서 10년, 앞으로는 더 짧아질지도 모르는 일입니다 빨리 기종을 확정하여 실력을 유감없이 발휘하는 길만이 항공산업을 발전시키는 길이라고 생각됩니다 우리 항공산업의 발자취와 개발의 중요성을 재인식하고, 국민과 호흡을 같이하는 새시대에 걸맞는 발전전략 차원에서, 정부의 구체적인 지원정책을 위시한 자세한 홍보의 필요성과 함께 기종선정이 조속히 마무리 되어야 합니다

This article intends to provide a direction for reconstructing the national regime of archival appraisal in electronic record environments. Functional appraisal, which inevitably carries out for appraising electronic records, has defects in aspect of selecting archives important in a national point of views. To do so, this article discusses defects of functional appraisal, and then suggests the necessity of archival appraisal strategies that complements functional appraisal. To investigate this archival appraisal strategies, it analyzes Australia's Whole-of-Government Functional Analysis, United Kingdom's Acquisition Policy and Appraisal Policy, Germany's Cooperative Cross-Archives Appraisal and Canada's Macro Appraisal. Ultimately, this analysis is able to establish a base of the regime of archival appraisal which will harmonize primary value at current stage with secondary value at non-current stage in a national point of views.

Although the important information are significantly increasing in the Web, it is easily disappeared because of the Web's characteristics. The purpose of this paper is researching and developing of base technology for archiving web records. First developing about the workflow which is the procedure of web archiving, and developing about metadata elements, the essential condition of preserving web records and accessing archived resources. Finally developing the architecture defined the overall items of web records archiving.

Assuring that the integrity of digital contents is reliably maintained is an important component of long-term digital preservation. The purpose of this study was to examine and analysis the best practices of digital preservation policy and provide the basis theory for establishing a preservation policy for maintaining the integrity of digital contents. In order to achieve the purpose of the study, we examined the digital archiving practices for maintaining the integrity of digital contents. Especially, we focused on the storage media and file formats, the media and format conversion, disaster prevention and recovery, management and handling, inspection and monitoring, and security policies.

This article identifies an emerging research paradigm and monitors the changes in digital preservation area using CiteSpace, a Java application which supports visual exploration with knowledge discovery in bibliographic databases. 74 articles on digital preservation field covering the time period from 1990-2005 were extracted from Web of Science. According to the result of analysis, core knowledge domains in digital preservation are technical preservation strategies, information network and preservation system, knowledge management and electronic government.

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.

The purpose of this study is to suggest the directions for building national digital archiving strategies. This present paper begins with surveying S&T information resources especially in public sector, and analyse the priority criteria for appraising and selecting the resources for long-term preservation. Emphasis is placed on identifying the critical tasks for each type of resources including scientific data, technical reports, theses, journal, web, e-prints, etc. and some levels of organizations in the national digital archiving framework. Based on the analysis, it suggests some strategic agenda for developing national digital archiving system.
