The key to the long-term preservation of electronic records is the long-term retention of the bitstream that contains the original functional attributes and appearances of the electronic records that were originally created and utilized. Considering economic and technical aspects, most of the major domestic and foreign archives have adopted a migration strategy that allows conversion to a new format depending on the stability and reliability of the format containing the original bitstream. However, as the type of electronic records varies and its scope continuously expands, several problems arise if a single migration strategy is observed. Therefore, the applicability of the emulation strategy is examined in this paper to reproduce the system and application environment where electronic records are created and utilized. As such, electronic records can be maintained without any changes in the bitstream by utilizing cloud computing technology.

Electronic record types are becoming diverse, and "composite electronic records," which are made up of various types of electronic records associated with functionality or user interaction that does not exist in current electronic document formats, are increasing. To ensure a continuous access to composite electronic records, metadata construction is a prerequisite for electronic records archiving. In this paper, we propose a metadata that can support archiving of composite electronic records associated with interactive functionality. The common elements were derived from an analysis of both domestic and international file format registry projects, and metadata elements related to functional requirements were identified from the analysis of the records on nursing education e-learning contents. We proposed the metadata elements for archiving composite electronic records, which consist of 25 high-level elements and 138 subelements.

Libraries and Museums have used archiving systems to preserve digital contents. Especially, university libraries mainly archive research resources including research papers. To the best of our knowledge, we proudly propose an educational repository oriented to archive overall educational process for the first time. To design the repository, we choose educational resources which need to be archived. Then, digital formats appropriate for long-term preservation are heavily discussed. Based on the design, we have practically implemented the system using representative repository software : DSpace, EPrints, Fedora, Omeka. Finally, educational resources of the specific subject are archived on each system, and the result of comparison is presented.

In this paper we explain the definition and component of electronic records, and reestablish the principle of the preservation. Also we discuss the conceptual approaches and requirements for long-term preservation in an electronic environment. The preservation in digital environment is to protect itself of record identity with the reliability and authenticity, and to ensure the accessibility of records. It needs to be periodical migration along with digital environment change for the long-term preservation of the electronic records. and to select software independent standard format. to ensure the integrity of electronic records along with this preservation strategy, process and relative information required for digital preservation are to record in the form of metadata. The preservation system is separated into four functional entities ; registration process, preservation process, access process, main record management system. Also, this article is conceptually to introduce the selection criteria of storage media, the security provision for the archive collections and the disaster recovery which apply to the digital archives.

In this paper we implemented various image processing filtering using the format converter. This design method is based on realized the large processor-per-pixel array by integrated circuit technology. These two types of integrated structure are can be classify associative parallel processor and parallel process DRAM (or SRAM) cell. Layout pitch of one-bit-wide logic is Identical memory cell pitch to array high density PEs in integrate structure. This format converter design has control path implementation efficiently, and can be utilize the high technology without complicated controller hardware. Sequence of array instruction are generated by host computer before process start, and instructions are saved on unit controller. Host computer is executed the pixel-parallel operation starting at saved instructions after processing start. As a result, we obtained three result that 1) simple smoothing suppresses higher spatial frequencies, reducing noise but also blurring edges, 2) a smoothing and segmentation process reduces noise while preserving sharp edges, and 3) median filtering may be applied to reduce image noise. Median filtering eliminates spikes while maintaining sharp edges and preserving monotonic variations in pixel values.

Social Network Service (SNS) has gained great popularity. Recently, facebook has been used most active. Most of government ministries of Republic of Korea operates facebook. In the case of facebook, it takes advantages of possibilities to inform the direction of policy to aggregate opinions of people for issues. Information gained from facebook has a very important value to be reflected in the policy or to understand public opinions. Long-term storage for this information should be considered. In the case of overseas, tools for long-term storage of documentary facebook have recently been developed. However, it does not save all the data in facebook and ignores the principles for long-term storage. These tools are limited to a simple backup. Therefore, this study aims to investigate how to reproduce, store and collect facebook page records of the government ministries.

Due to the trend toward computerization of business services in public sector and the push for e-government, the volume of records that are produced in electronic system and the types of records vary as well. Of those types, dataset is attracting everyone's attention because it is rapidly being supplied. Even though the administrative information system stipulated as an electronic record production system is increasing in number, as it is in blind spot for records management, the system can be superannuated or the records can be lost in case new system is developed. In addition, the system was designed not considering records management, it is managed in an unsatisfactory state because of not meeting the features and quality requirements as records management system. In the advanced countries, they recognized the importance of dataset and then managed the archives for dataset and carried out the project on management systems and a preservation formats for keeping data. Korea also is carrying out the researches on an dataset and individual administrative information systems, but the official scheme has not been established yet. In this study the items for managing archives which should be reflected when the administrative information system is designed was offered in two respects - an identification method and a quality requirement. The major directions for this system are as follows. First, as the dataset is a kind of an electronic record, it is necessary to reflect this factor from the design step prior to production. Second, the system should be established integrating the strategy for records management to the information strategy for the whole organization. In this study, based on such two directions the strategies to establish the identification for dataset in a frame to push e-government were suggested. The problem on the archiving steps including preservation format and the management procedures in dataset archive does not included in the research contents. In line with this, more researches on those contents as well as a variety of researches on dataset are expected to be more actively conducted.

Recently, various methods of collecting and preserving social media have been discussed in the field of archives and records management as social media is actively used as a way of communicating with the public in the government. In the United States, there is a move to acquire and preserve social media at the government level, and the National Archives (UK) already provides social media archives to users through Twitter and YouTube. In this study, we proposed the features, acquisition methods of social media by type and the preservation model based on case study results in terms of acquisition and preservation of social media archiving. In order to verify the effectiveness of the proposed methods, this study was applied to the social media of Gyeongsangnamdo provincial government. The results of this study is meaningful in that it suggested acquisition and preservation methods through actual collected results and it is expected that it will be useful for establishing the models for future social media archiving.

This research compares and analyzes the legal deposit of national online electronic publishing and related laws that were recently amended in order to preserve the exponentially increasing number of electronic books(e-books). Based on the analysis, it also seeks ways to initiate a legal deposit system of e-books in South Korea. The research, therefore, defines the exact range and types of e-books. This research proposes three conditions to introduce the legal deposit system in order to preserve South Korean e-books. The first is to establish a clear definition and classification of e-books as data subject to legal deposit for preservation purposes. The second condition is to establish a legal system in order to deposit and collect network(online-exclusive) type e-books. The final condition is to reflect the opinion of publishers and to create security measures against any loss of the companies.
