Traditional paper records have two aspects such that the paper records are information, and are information media itself. The preservation media for the paper records seems to be another forms for original ones including microfilm and optical disks. On the other hand, new-coming electronic records lack the aspect of information media. To guarantee the existency of the original electronic records we need the preservation media for the electronic records, different from the media for the traditional paper records. The preservation media helps the Authenticity, integrity, and usability as well. This paper describes the need for the preservation media, identifies problems on the existing concept for them, derives the principles to resolve the problems, and suggests the management policy based on the principles.

The purpose of this study is to provide the methods of preservation for paper, microfilm, digital media. First of all, for acidic papers produced in 19~20 centuries, this study evaluates and analyses deterioration and factors causing deterioration. For book, also, environmental condition for preservation, and a preservation mechanism through acid-free procedure were suggested. Second for microfilm, it emphasized physical and chemical properties, oxidised substance during developing film, materials related to preservation. Third, for digital storages, storage conditions and needs, such as life-cycle and capacity were introduced.

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 solids and the fluids in porous media have a relative velocity to each other. Due to physically and chemically different material properties and their relative velocity, the behavior of saturated porous media is extremely complicated. Thus, in order to describe and clarify the deformation behavior of saturated porous media, constitutive models for deformation of porous media coupling several effects need to be developed in frame of Arbitrary Lagrangian Eulerian(ALE) description. The aim of ALE formulations is to maximize the advantages of Lagrangian and Eulerian elements, and to minimize the disadvantages. Therefore, this method is appropriate for the analysis of porous media which are considered for the behavior of the solids and the fluids. For this reason, mass balance equations for saturated porous media are derived here in ALE description frames. ALE formulations of mass conservation for the solid phase and the fluid phase are expressed. Then, linear momentum balance equation for porous media as multiphase media is expressed.

Microfilm has been used as an important media for enhancing the long term preservation and improving access to records. However, because of technological changes, there have been discussion about whether we should keep using microfilm. This paper presents survey results to review the preservation methods such as microfilming and digitization. The content is organized according to the trends found in the survey from six archives and libraries, including Germany, France, the United Kingdom, and Japan. Moreover, we refer to other papers from the USA and Japan to require further review if we can accept digitized records as the original records, etc. The rest consists of four parts: the use of microfilm as a storage media for preservation, the authenticity of digitized records, the management of records on microfilm, and the preservation of electronic media. Finally, we would like to suggest the way to improve preservation systems and digitize records more widely.

모든 기록매체의 장기보존성과 신뢰성은 보존에 있어 중요한 요소 중 하나이다. DVD 광기록매체 또한 신뢰성을 평가하기 위한 다양한 국제표준 및 연구가 진행되었다. 국가기록원은 각급 기관에서 생산되어 이관된 다양한 종류의 DVD 광매체를 보존하고 있으며, 이에 대한 상태평가를 위해 선행된 표준 및 연구 내용을 바탕으로 이관된 광매체에 대한 상태를 측정을 하였다. 본 연구에서는 이관된 DVD 매체에 대한 평가 기준을 8개의 연속된 ECC블럭의 PI 에러값을 사용하였다. 측정된 PI 에러 값은 생산년도, 제조회사, 에러 발생 위치로 분류하였으며 시간에 따른 열화 정도, 기록 품질 그리고 에러 발생 위치에 따른 매체 상태와의 연관성을 연구하였다.

전자문서의 보존은 보존관리인들에게 새로운 과제를 가져다 주었으며, 오늘날처럼 정보를 파악하기 힘든 적은 없었다. 문서가 일단 매체로 전환되면 수 백년 혹은 수 천년까지 영속할 수 있었으나, 전자문서는 사라질 위기에 있어서 물리적으로는 이용할 수 없고 법적으로는 적합하지 않아 받아들여질 수 없는데, 이러한 현상이 나타나는 원인은 매체가 더 이상 쓰이지 않는다든가, 기술력이 시대에 뒤떨어져 쓰이지 않는 다든가, 표준이나 안내지침이 부족하거나, 보존관리인들의 전자문서관리와 보존을 위한 계획안을 마련하지 못한다는 등의 이유때문이라고 할 수 있다. 종이자료와 달리, 전자매체는 물리적인 객체로 보존될 수 없고, 전자문서는 단지 문서를 재생할 능력을 보존할 뿐이다. 그리하여 전자문서의 적절한 관리가 문서보존에 더 할 수 없이 중요하게 되었으며 전자정보관리의 초창기인 지금 우리가 최신의 문화유산이 지닌 잠재력과 함정을 모두 이해하기 힘들기 때문에 이를 완전히 이해할 때까지 완전한 보존해야 할 것이다.

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.
