This study investigated the perception and experience of users who visited in Seoul office of the National Archives, a branch of the National Archives of Korea(NAK). For collecting data, the study utilized the Researcher Survey Toolkit developed by Archival Metrics Project and revised the questionnaire to reflect services of NAK. Questionnaires completed by 47 users were collected and analyzed, and interviews with one survey respondent and two staff were performed. It was found that the purpose of the visit is mostly to identify records that prove land ownership of users' ancestors. Types of records frequently used were also those concerning lands and forests. User feedback on the staff was generally positive, and users perceived them to be helpful and kind. However, there was an opinion that the staff did not provide accurate information about whether NAK hold records that the user wanted to find. The staff also said that it was challenging to confirm where requested records are located when providing services for users. User evaluation on the usefulness and the ease of use of NAK portal services was not very positive, and it was perceived to be very inconvenient to search in the portal. Overall, users were satisfied with the services of NAK, although some users suggested that services need be provided efficiently, and NAK must clarify the criteria for the non-disclosure of public records.

One of the most important point in the Internet crime investigation is tracing back and pointing out a criminal host. However, criminals can forge a crime record stored in the crime host, or can utilize malicious applications in order not to leave a crime record. In addition, criminals can change the source IP address of a crime host and deny their involvement. In this study, we suggests the Network Forensic Evidence Generation and Verification Scheme (NFEGVS) to rectify the current limitation of Network Forensic technologies. This scheme can prove who and when the crime has occurred. In addition, this prevents leaking of symmetric key for guaranteeing certification and integrity of Forensic Evidence by proposing the Timestamp Secret Key Distribution Scheme, and minimizes performance degradation of router when generating forensic evidence with the Flow-Based Selection Scheme. In this paper, we implement the proposed scheme and evaluate overall performance of the proposed system.

The big problem of accidents at sea is negligent watch, it causes collision, fender bender, stranding, rollover, and sinking of fishing vessel. Most accidents happens without an eyewitness, it is difficult to identify the cause of the accident. VDR(: Voyage Data Recorder) is needed to identify a cause of the accident, the VDR is not usually used for fishing vessel because of high cost. Thus, this paper designs and develops a VDR system for fishing vessel. If the system is used, cause of a sea accident can be quickly identified. Also, a VDR system can be used for appropriate measures to fix a cause of the accident. Finally, it also can be helpful to prevent maritime accidents.

This study presents the problems in the records management of special project teams at J University. Methods for the improvement plan were also proposed in this study. To achieve these objectives, five special project teams from J University, which were supported by the Ministry of Education, were selected. To collect relevant information, twelve staff members and experts were then interviewed. The records produced by the projects should be managed as evidence of the project evaluation and transparent budget execution. Proper management can be a good material for research. However, the management of project teams is vulnerable in comparison with the records of other universities. The main reason is that although the project team produces various types of records, it has not been recognized as the Department of Processing. Another reason is that the project teams are temporary institutions and do not possess authority over the entire project process. To solve the aforementioned problems, this study proposes improvement plans in the following aspects: institutional, cognitive, administrational, and systemic. In the institutional and cognitive aspects, policy and regulation were set up. In the administrational aspect, the relation and role of each element were defined. In conclusion, the plans for building the Combined Archives System were suggested. In addition the methods on how to connect with the KORUS-which will be introduced in 2017-and the system currently being used are proposed.

Archival materials in film archives is a memories and archival documents of human which is generated from cultural activities of human being, and provided long-term relevant information. However, it is different general public audio-visual records because main purpose of representing culture to create the contents of private sector rather than evidence of the factual information of public service activities. Therefore, should determine the description principle and rule in order to reflect specific physical, intellectual characteristics. So as to control the description, that is need in the textual standards to base the specific purposes and rules thus analyzed the international description standards as Dublin Core, ISAD(G), FIAF Cataloguing Rules For Film Archives. As a result, more effectively to describe archival materials in film archives required significant modifications in the organizations of the areas and the elements. This study argues that first, to divide existence the concept and the reality (work/item) of archival materials in film archives. Second, to need understanding and indicating their content, context, structure. Third, to establish of the areas and the elements including a characteristic of it. The final suggestion organizes separately to 6th and 8th areas, 22th and 25th elements in two parts. This conclusion does not prepare to refer the status and/or policy of a particular film arhicve, can be set accordingly to a specific elements or sub-elements by the film archives.

This paper has two aims (1) to address the common European past by way of considering the development of the official archives of the European Union; and (2) to give specific attention to the activities of archivists in Germany. The EU archives contain the all the documents officially recording the common history of European integration from the establishment of the European Coal and Steel Community in 1951. It was at the beginning of the 1980s, thirty years after the production of these documents, however, that the Archives of the European Community (EC) began to be systematized for public use when the European University Institute in Florence in Italy was chosen as the deposit location for the archive. After the coming into effect of the Maastricht Treaty in 1993, the EC Archives were renamed as the EU Archives. Through the cooperation of the national archives of the each Member State of the EU with this EC Archives common norms regarding deposit were developed. This archives is a veritable gold mine for serious research into all and any official aspect of the institutional and policy history of today's EU, so for the formation of common European identity. The denazification process using the evidence of the archives contributed to the orientation of the New Germany towards Europe. The German archives then have been contributing to the redressing the past to a significant degree since after the Second World War. More recently, the establishment of the "Memory, Responsibility, and Future" Foundation in 2000 in Germany made possible cooperations with the archives of the East European countries and especially for the purpose of the providing evidence about former enforced workers under the Nazi regime. There has thus been developed European-wide networks among archives. These developments have furthered the common redressing of the European past and this process in turn has been contributing the enhancing the European spirit and identity. The thesis of this paper then is that historical research based on the EU archives and individual Member States can not only illuminate in great detail the stages of the history of European integration to date. The dissemination of such research can itself contribute to the process of the spreading of supranational ideas beyond Europe to other regions of the world.

해쉬 알고리즘은 디지털 포렌식 수사에서 디지털 증거의 무결성을 증명하기 위해 널리 사용되고 있다. 디지털 증거의 무결성은 동일한 데이터에서만 같은 해쉬 값이 계산된다는 성질에 의하여 증명된다. 일반적으로 동일한 데이터에 대한 해쉬 값은 서로 다른 포렌식 툴을 이용해서 계산을 해도 항상 같은 값이 출력될 것이라고 인식하고 있다. 하지만, CD-R 미디어의 경우에는 해쉬를 계산하는 포렌식 툴에 따라 값이 다르다는 특성이 있다. 이것은 해쉬 값이 CD 제작 도구에서 CD-R 미디어에 데이터를 기록하는 방식과 각 포렌식 툴 별로 CD-R 미디어를 인식하는 방식에 의해 영향을 받기 때문이다. 이러한 특성은 CD-R 미디어의 무결성 증명 시에 문제가 될 여지가 있기 때문에 디지털 포렌식 수사 절차에서 반드시 고려되어야 한다. 본 논문에서는 CD-R 미디어의 해쉬 값에 영향을 주는 요소에 대해 기술하고, 실험용 CD-R 미디어를 제작하여 대표적인 디지털 포렌식 도구들을 이용해서 확인한다. 이를 통해, 디지털 포렌식 수사 절차에서 CD-R 미디어에 대한 해쉬 값을 계산할 때 고려해야 할 사항을 제안한다.
