The target of managing electronic records should be the trusted record services to the end-users. The natural characteristics of electronic records yields the drawback in the authenticity aspect and in the integrity aspect, and current standards and methodologies have beed developed to treat this drawback. However the authenticity and the integrity concepts is hardly separated each other and too completed, so alternative "source" concept is introduced and a verification strategy for the origin of electronic records is discussed in this paper. According to this concept, current standards and methodologies may be criticized for the negligence of necessary information organizing/verification, the doubtful long-term verification, and the missing counter-strategy for the verification-failed records. To solve this, needed facters for origin verification is described, new preservation format divided into temporally-fluctuating (variable) part and immutable (fixed) part is proposed, and a strategy to prevent, avoidance, and detection/recovery important records is suggested.

In consideration of the drastic transformation of records management environments, this study aims to suggest the directions for redesigning the electronic records management policies at a national level. First, it clarifies the four implicit objectives of electronic records management policies since the 2006 amendment of the Public Records Management Act, such as comprehensiveness for ensuring the appropriate management of any type of digital records, digital-friendly processes for records management, proper management for guaranteeing the evidential value of digital records, and long-term preservation of digital records. Second, it examines the challenging environmental factors in the areas since 2006. Third, it reviews the achievement of the policies as well as failures based on analyzing the policy documents and data from the National Archives of Korea. Fourth and finally, it suggests core areas and directions for redesigning the electronic records management policies, emphasizing the inclusiveness for data-type electronic records.

Korea Institute of Science and Technology Information (KISTI) is a Worldwide LHC Computing Grid (WLCG) Tier-1 center mandated to preserve raw data produced from A Large Ion Collider Experiment (ALICE) experiment using the world's largest particle accelerator, the Large Hadron Collider (LHC) at European Organization for Nuclear Research (CERN). Physical medium used widely for long-term data preservation is tape, thanks to its reliability and least price per capacity compared to other media such as optical disk, hard disk, and solid-state disk. However, decreasing numbers of manufacturers for both tape drives and cartridges, and patent disputes among them escalated risk of market. As alternative to tape-based data preservation strategy, we proposed disk-only erasure-coded archival storage system, Custodial Disk Storage (CDS), powered by Exascale Open Storage (EOS), an open-source storage management software developed by CERN. CDS system consists of 18 high density Just-Bunch-Of-Disks (JBOD) enclosures attached to 9 servers through 12 Gbps Serial Attached SCSI (SAS) Host Bus Adapter (HBA) interfaces via multiple paths for redundancy and multiplexing. For data protection, we introduced Reed-Solomon (RS) (16, 4) Erasure Coding (EC) layout, where the number of data and parity blocks are 12 and 4 respectively, which gives the annual data loss probability equivalent to 5×10^-14. In this paper, we discuss CDS system design based on JBOD products, performance limitations, and data protection strategy accommodating EOS EC implementation. We present CDS operations for ALICE experiment and long-term power consumption measurement.

New environment change of electric power system focused in consumer's energy supply and demand. But electric power reliability preservation and reliability improvement countermeasure also need for long-term. It is need that change equipments that is composing electric power system in well-timed time and by maintaining, prevent breakdown beforehand and prevent consumer's power interruption by equipment fail. However, as only quantitative estimation is available by reliability estimation method that is presented in existing, it is no to use in dictionary fault prevention. Therefore, applied optimum reliability preservation through existent equipment fault data analysis of electric power system in equipment replace side, and this when maintain equipment replace of electric power system for reliability preservation using responsiveness analysis to base ordering evaluate. In existing about main equipment plain that this paper is power system the valued failure rate use this by score and precedence of electric power system equipment for replace of system considered expense.

Many historical archives have been deteriorated by aging with time. Various kinds of defects such as worm-hole, yellowing, brittleness are observed and their severity was dependent on raw material type, storage condition, and so on. For a long-term use and storage, a proper preservation treatment is required. Many studies on preservation and conservation have been carried out on hanji which was made from mulberry fiber, but there are few concerns on foreign paper. Therefore, aging and chemical strengthening treatment was done on paper made of bamboo and wood fibers depending on aging condition, the type and pickup weight of chemicals and treatment method. When methyl cellulose was treated with impregnation or brushing, the aged paper was strengthened effectively. The strengthening effect by chemicals was dependent on the aged condition of the paper.

In the fast growing digital environment, assuring continued authenticity is an essential and intransigent preservation consideration for digital data and records. Several key issues need to be addressed, including: What are electronic records and data?; Which intellectual and technical elements of data and records are essential for assuring authenticity in electronic format?; How should these be maintained and preserved over time?; How are authentic data and records used in various systems of practice?; and What are the best strategies of preserving authentic electronic records and data?. There have been many research projects to answer these questions to date. This paper discusses the characteristics of electronic records in light of preservation consideration and reports the activities and findings of some of the research projects in brief. This paper focuses on explaining the InterPARES (International Research on Permanent Authentic Records in Electronic Systems) Project, which is defining requirements for authenticity that can help develop strategies for long-term preservation in electronic records. To identify those requirements, more than thirty case studies have been conducted with government agencies, academic institutions, and various organizations in America, Canada, Europe, Asia and Australia and models developed for appraisal, preservation, and strategies in relation to the management of electronic records. The paper also suggests research questions and implications for preserving authentic electronic records as well as the encouragement for Korean research on digital preservation.
