Recently, according with a sudden increase of records produced and stored by digital way, it becomes more important to maintain reliability and authenticity and to ensure legal effect when digital records are collected, preserved and managed. On the basis of domestic legal procedure law and record management-related legislation, this paper considered judicial admissibility of evidence on electronic records managed by National Archives of Korea and drew potential problems when these are submitted to court as a evidence. Also, this paper suggested a plan applying digital forensics technique to electronic records management to ensure admissibility of evidence about electronic records stored in National Archives of Korea.

재시작 회복시 수행해야 할 작업략을 줄이기 위하여 주기적으로 수행되는 검사점 중 퍼지 검사점은 정상적인 트랜잭션들의 수행과 병행하여 수행된다. 트랜잭션들과 퍼지 검사점의 수행시, 로그 레코드 기록의 순서화를 위한 로그 래취를 획득한 상태에서 로그 레코드를 기록할수있으며, 트랜잭션 엔트리의 무결성을 보장하기 위한 트랜잭션 래취를 획득한 상태에서 트랜잭션은 로그 레코드의 기록과 관련된 트랜잭션 상태를 변경할수 있으며 검사점 프로세스는 트랜잭션의 상태를 검사할 수 있다. 퍼지 검사점과 트랜잭션들이 수행이 비동기로 수행되는 상황에서 로그래취와 트랜잭션 래취의 획득 및 해제 방법이 적절하지 못한 경우, 퍼지 검사점이 어떤 트랜잭션의 트랜잭션 상태를 검사하기 전에 그 트랜잭션에 의하여 기록된 로그 레코드이지만 그 퍼지 검사점이 그 트랜잭션 상태를 검사할때까지 그 로그 레코드의 기록상황이 그 트랜잭션의 트랜잭션 상태에 반영되지 않은 경우가 발생할수 있다. 이 경우, 기록 상황이 트랜잭션 상태에 반영되지 않은 그 로그 레코드를 그 퍼지 검사점에 대한 그 트랜잭션의 상태미방영 로그 레코드라고 한다. 본 논문은 상태미반영 로그 레코드를 발생시키는 상황들을 분석하고, 상태미반영 로그 레코드의 발생에 따른 문제점들을 기술하며, 상태미반영 로그 레코드의 발생에 대하여 전면 방지 기법, 일부 방지 기법 그리고 전면 허용하지만 회복시 이를 해결하는 기법등 세가지 해결책을 제시한다.

For the purpose of technological analysis in the marine accidents and their prevention, IMO have made it obligatory to load VDR which is similar to the black box in aircraft. However, in case of body sinkage, capsizing, stranding and plunging which are almost 10% of marine accidents, it is difficult to take out the necessary data from the VDR in order to analyze the cause of them. Therefore, this paper apply the navigation dangerousness evaluation technology to the VDR to improve its performance. And we suggest that the vertical acceleration which is one of the factors for evaluating seakeeping performance of a ship is to be added in the existing VDR record data recommended by IMO.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.

The idea of the vertical filing had been introduced in Japan at the beginning of the 20th century. This is regarded as a root of the management of business records and office works. After the Secund World War, The Occupied Army introduced the American method of the document management and the method as the filing system had been generalized among many offices. However, the filing method bad been regarded the needed skills for clerical staff. The business documents and records have increased in volumes and recognized their value as information resources in business and management. These movements have become a good grounding in introducing and development of records management. To spread the idea and method of records management in business offices, it is required that academic research and training systems must be developed and established. In such situation, The Records management Society, Japan has been established in1989 and the graduate corse on records management has been established in Surugadai Univ. in 1999. Those are the center of research and studying activities on records management in Japan.

3D object contents are used for various applications in the Web virtual space, where the main concerns are to navigate the 3D virtual space and visualize 3D objects. The techniques to manipulate 3D objects like disassembling and assembling and to record the manipulation process are the very first step. Until now, we can record only the result of 3D object manipulation. Thus, we have tried to study the representation technique to record meaningfully and replay the manipulation process of 3D structured objects. We analyzed the structures and their relations between components to construct 3D objects that are described in XML or VRML. Compared to the previous method, we studied a XML based annotation technique to record and store selectively by user. This technique makes 3D structured objects be used in the various applications by the selective recording and also selective replaying.

To develop a public services framework for the promotion of the public records use of the regional archives in Korea, we analyzed the previous related studies and observed the public services of the renowned overseas regional archives through the we sites. Then, the web 2.0 technology and its application to archives services have been studied. Based on the analysis, a public services framework consisting of 4 phases such as basic services, extended services I, extended services II, interactive services was developed. This framework of 4 phases is not a fixed universal system. Each of the regional archives would select the services they offer according to the budget, personnel, as well as the user community. Finally, community survey, user satisfaction evaluation, and the establishment of specific service guidelines are suggested for the advancement of the public services.
