A necessity increases but since a many manpower and the budgets are insufficient for archiving all digital resources the digital archiving at the science information center or the digital library has to be successively processed according to the priority. Therefore, in this research, whether it has to archive among digital resources which Korea Institute Science and Technology Information(KISTI) hold around any kind of contents or not makes analysis and valuation around the value for use. The priority evaluation plan that can become the system analysis and reflection based on this automatically tries to be proposed.

Classical novae (CNe) are interacting binary systems whose outbursts are powered by a thermonuclear runaway in accreted material onto the surface of a white dwarf (WD). The secondary star in such systems fills its Roche lobe and material is transferred onto the WD primary star via an accretion disk. Recurrent novae (RNe) show many similarities to CNe, but have had more than one recorded outburst. RNe play an important role as one of the suspected progenitor systems of Type Ia supernovae, which are used as primary distance indicators in cosmology. Thus, it is important to investigate the nature of their central binary systems to determine the relation between the parameters of the central system and the outburst type, and finally ascertain the population of novae that might be available to give rise to the progenitors of Type Ia SNe. A low outburst amplitude is adopted as a criterion that may help distinguish RNe from CNe and was therefore used to select targets for observations from ground-based observatories including the Liverpool Telescope and the Southern African Large Telescope as well as the full-sky space-based archive of the Solar Mass Ejection Imager (SMEI). We found that at least four objects currently classified as CNe are possibly RNe candidates based on their quiescent spectra. We also searched the SMEI archive for additional outbursts of bright CNe that might otherwise have been missed but did not find a conclusive example.

웹의 성장으로 사용자는 언제 어디서든지 유용한 정보의 이용이 가능해졌다. 웹이 광범위하게 사용됨에 따라 정보를 획득하기 위해 대다수의 사용자들이 웹을 의존하고 있다. 그러나 웹상의 모든 정보는 정보가 저장되어 있는 서버의 관리자들에 의해 계속적으로 갱신 또는 삭제되어 가고 있어 기존의 정보들은 그것의 중요성 여부와 관계없이 대다수의 정보가 소멸되고 있다. 따라서 오랜 기간에 거쳐 생성된 웹상의 중요 데이터(importance data)들을 효율적으로 활용하기 위한 웹 아카이브(archive) 시스템이 연구되었다. 그러나 현재 존재하는 웹 아카이브 시스템은 갱신되기 이전의 데이터를 다루기 위한 체계적인 처리기법을 제시하지 못하고, 수집된 데이터들에 대한 연관관계를 저장하지 못하여 데이터 관리에 있어 비효율적이라는 문제점을 가지고 있다. 이에 따라 본 논문에서는 웹으로부터 다운로드한 데이터를 레포지토리(repository)에 효율적으로 저장하기 위해 설계된 대표적인 WebBase를 기반으로 하여 갱신되기 이전의 모든 정보들에 대한 내용을 히스토리(history) 저장소내에 저장하여 정보를 효율적으로 활용할 수 있는 웹 아카이브 시스템의 구조를 제안한다.

As data management and intelligence capability become proxy indicators of national power, the risk provoked by high depending on digital technology ironically increases. The quicker the changes come to be, the more important digitizing existing data and management of digital data are. The management of archaeological data could not be exceptional. It has to be performed in a more comprehensive, systematic and rapid manner. In order to perform the task, the nature of archaeological data contained in the digital archive should be properly recognized in advance: the primary data are generated by excavation as a process destroying their sources, the data are enormous in type and quantity, including long-term and various human experience, and the natural extinction of primary data in handwritten form is likely to be more crucial than in any other discipline. These characteristics of archaeological data unimaginably devastated the possibility of recovering archives, when we face a digital dark age. Considering both recent trend and the nature of archaeological data mentioned above, we can derive strategies for building a sustainable archaeological digital archive. As an archaeology-major consumer of the digital data, I propose four strategic considerations: ① establishing a system of digital data literacy; ② enhancing evaluation and capability of data reuse; ③ building an international data sharing system; ④ developing it into the platform for digital archaeology.

Maul is a rural community with common culture and self-government system and generally consists of tens of houses living together in Korea. Maul is different from a village in the West. Maul archive is a community archive of a maul. It is not only the space to record the life of residents, history and culture of a maul but also the space to realize democracy by the participation of maul residents and to satisfy the cultural life of current residents. Nowadays, it is very important to establish maul archives to connect mauls and to communicate with the outside world, to reinforce the orignal form in maul culture and revive the alienated maul culture. To establish the maul archives, it is necessary to draw the recognition and continuous interest of the central and local government and scientifical study of scholars. The first step to found maul archives is to organize a committee. Then the committee will benchmark the preceding practices, collect, record and manage the maul archives. The maul archives is recommended to be housed in an existent traditional house with some remodeling for spaces of display and education, preservation and management. I believe that the maul archive is culturally meaningful for the resident. They will enjoy and develop their lives better, connected to outside world. The co-operation of the scholar, the resident, and the government will foster the maul archive to a success.

With the enactment and enforcement of the 「Public Records and Archives Act」, the Tottori Prefectural Archives newly enacted the "Records Management Ordinance" through a comprehensive review of the previous archive function. In accordance with this ordinance, which came into effect in April 2012, Tottori Prefecture expanded the records management institutions (Public Security Committee and Police Headquarters, etc.) A series of archive systems were improved, such as the expansion and reinforcement of the authority to appraisal and select. In addition, the Tottori Prefectural Archives went further and implemented the "Ordinance on the Preservation of Historical Documents, etc." from April 2017. Through this, the municipalities unit basic local government's record management support work was set as a unique function of the local archive, and a linkage and cooperation system was established for the preservation of private records of the prefecture area as well as the basic local area together with cultural heritage institutions such as museums and libraries. As a reference case that continuously guarantees the performance of various activities based on the mission and vision of the local archives in Korea that aim for 'autonomy of records' on the poor archival culture soil, it is worth paying attention to the case of continuous record management reform of the Tottori Prefectural Archives through the enactment of the original role and function of the archive.

The purpose of this study is to develop a metadata AP for managing the person and organization name authority data in the National Debt Redemption Movement Digital Archive, a small-scale digital archive. The design principles and core metadata elements were derived by analyzing person/organization(group or corporateBody) metadata standards, implementation practices, and guidelines of libraries and archives, and mapped to the National Debt Redemption Movement person/organization name thesaurus data and the Wikidata Linked Metadata Model, resulting in 10 elements in the identification area, 14 elements in the content area, 8 elements in the relationship area, and 4 elements in the control area. A simple structure schema was applied so that it can be applied even in small organizations, and for interoperability, the schema was proposed with reference to DublinCore and SKOS schemes, and the applicability was confirmed based on actual data. The results of this study can be utilized as a basis for institutions that recognize the importance of data management but have difficulty in applying it in practice, when they want to prepare a system for managing their own authority data.

Hadoop is composed with MapReduce programming model for distributed processing and HDFS distributed file system. Hadoop is suitable framework for big data processing, but processing of mass small files have many problems. The processing of mass small file in hadoop have problems to created one mapper per one file, and it have problems to needed many memory for store of meta information of file. This paper have comparison evaluation processing method of mass small file with various method in hadoop platform. The processing of general compression format is inadequate because of processing by one mapper regardless of data size. The processing of sequence and hadoop archive file is removed memory problem of namenode by compress and combine of small file. Hadoop archive file is faster then sequence file about combine time of small file. The processing using CombineFileInputFormat class is needed not combine of small file, and it have similar speed big data processing method.

Record management, especially in schools as an institution's information centre, needs serious attention from government agencies. Under record management policy, there needs to be practical guidance on record management specific to schools. This paper aims to construct a record management model based on the Eight Indonesian Education Standards to support school accountability in Indonesia. The urgency of this paper in filling the gap in the Electronic Record Management System (ERMS) role is primarily to support school accountability. It is important to include educational laws and regulations in Indonesia to be a foundation in archive management, including preparing the ERMS. This study aims to develop a model of record management in schools. The final stage in this research is to find the final model. The final model is a model that experts and practitioners have validated. A total of 30 records managers were selected for the interviews. Furthermore, the trial was carried out in 30 senior high schools. The research sampling consisted of representatives of archive managers at selected schools from five islands in Indonesia (Kalimantan, Java, Papua, Sumatra, and Sulawesi). Our research findings show that conceptual models meet valid criteria and significantly impact archivist performance in better schools. The practical implication is that the archival management model based on national education standards policies contributes to practical archives and records management to support school accountability.

Data storage related with writing and retrieving requires high storage capacity, fast transfer rate and less access time in. Today any data storage system can not satisfy these conditions, but holographic data storage system can perform faster data transfer rate because it is a page oriented memory system using volume hologram in writing and retrieving data. System architecture without mechanical actuating part is possible, so fast data transfer rate and high storage capacity about 1Tb/cm3 can be realized. In this paper, to correct errors of binary data stored in holographic digital data storage system, find cluster centers using clustering algorithm and reduce intensities of pixels around centers. We archive the procedure by two algorithms of C-mean and subtractive clustering, and compare the results of the two algorithms. By using proper clustering algorithm, the intensity profile of data page will be uniform and the better data storage system can be realized.
