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.

디지털화의 눈부신 발전으로 인해 대부분의 기록물들은 종이 위주의 생산방식에서 전자문서방식으로 패러다임이 변하고 있다. 이에 따라 정부적인 차원에서 이러한 전자문서에 대한 장기보존에 대한 연구가 요구되고 있으며, 이미 많은 국가에서 표준을 정의하여 기록물에 대한 장기보존 기법에 대한 연구가 활발하게 진행되고 있다. 이들 시스템의 대부분은 IS014721 표준으로 지정된 디지털 객체의 장기보존을 위한 참조모델인 OAIS(Open Archival Information System) 정보패키지 개념으로 사용한다. 이 정보패키지 방법은 보존하고자 하는 콘텐츠에 메타데이터를 두어 콘텐츠와 함께 인캡슐레이션을 함으로써 보존 및 활용을 가능하게 해준다. 그러나 기존에 연구는 장기보존에 관한 시스템 설계가 대부분이었고, 실제로 패키지를 구성하고 저장하는 방법에 대한 연구는 미진한 실정이었다. 따라서 본 논문에서는 멀티미디어 기록물을 위한 장기 보존 패키지를 설계 및 적용 하고자 한다. 이를 위하여 OAIS 참조모델을 기반으로 장기 보존을 위한 대용량 비디오 관리 시스템의 보존 정보 패키지의 구조를 제안 하였다. 장기보존 패키지는 기록물 그 자체와 기록물을 보존하기 위한 정보, 기록물을 설명하기 위한 정보를 저장한다. 또한, 추후 활용과 배포를 위하여 기록물 패키지의 정보를 저장하는 Meta-AIP와 실제로 기록물을 저장하는 Real-AIP로 구성되어 있다. 또한, METS를 이용한 실제 패키지의 예를 보임으로써 비디오 기록물 관리시스템에 적용 가능 함을 보였다.

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.

Recently, there are some discussions about cooperative library storage facilities as methods to relieve the pressure from shortage of library stacks in Korea. This study tried to inspect the preservation environments of 16 cooperative storage facilities in USA, Australia, France, Spain and Korea to help to prepare and establish cooperative storage facilities with ideal preservation conditions. To do this, some aspects of the preservation environments including basic conditions shelving system, HVAC(heating, ventilating and air conditioning) system, fire extinguishing system, security system and other preservation environments were compared and analyzed.

This study acknowledges that prevailing regulation concerning for the long-term preservation of electronic records focus mainly on document types, neglecting the preservation of electronic records from various administrative information systems. With the growing interest in data management in the era of big data, it is imperative to establish clear standards for the long-term preservation of datasets. The choice of preservation format for electronic records is based on the specific standards for each type of electronic record. These standards are formulated according to the significant properties relevant to the electronic record type. This study aims to identify the significant properties of electronic records of each record type, before creating specific preservation format selection criteria for these record types. To achieve this, we reviewed and analyzed R&D studies by the National Archives of Korea and the NARA in the United States. As a result of the research, 9 significant properties were identified for database-type entities, and 7 significant properties were identified for structured data-type entities.

Cell preservation is indispensable in animal cell culture process and should be established according to the cell characteristics. In this study, we experimented hypothermic preservation of CHO cells that is widely used in pharmaceutical industry to produce therapeutic proteins and established a stable method of preservation. The highest viability of CHO cells was obtained when the cells were preserved using rolling tube, which means the cells should be suspended to avoid the cell lumping during the preservation. Also, we obtained superior preservation result under the anaerobic condition. To evaluate the serum-free media as a preservation solution, we investigated cell growth after hypothermic preservation using serum-free media. High cell viability and normal cell growth was observed during 10 days using serum-free media. Moreover, we found that more effective preservation when ${\alpha}$-tocopherol and retinoic acid is added to media as an additive. In the case of 1 liter large scale hypothermic preservation using established protocol, cell viability and growth rate was obtained as good as small scale one. This study is considered to be helpful for hypothermic preservation of CHO cells and large scale hypothermic preservation may be available through the further studies.

The archives preservation chamber is an equipment that is able to store important archives with air-cleaning and isothermal-isohumidity control functions to permanently store archives in a highly safe environment. The chamber can only store small amounts of archives but it is crucial for organizations preserving archives to economically store a variety of archives, be it a medium or a small amount of documents. An arm of this study researches the current preservation status of the local record center to determine the need for such a chamber. In addition, in order to improve the air-cleaning and isothermal-isohumidity functions, the researchers of this study have conducted analyses to design the core parts. The preservation chamber that had been designed includes an archives preservation area, air-cleaning equipment, and environment measurement equipment. A preservation chamber is used to preserve small amounts of important archives safely. Thus, when a local record center is preserving various types of archives in small or medium quantities in a stack room, the preservation chamber can be used to aid their long-term preservation.
