컴퓨터에서 안정성은 가장 중요시된다. 파일 시스템의 안정성이 문제가 되어 시스템이 다운되거나 여러 가지 문제가 발생할 경우, 데이터가 손상 되거나 데이터 복구가 불가능하게 될 수 있다. EXT3 파일 시스템은 이러한 문제점을 보안하기 위해 기존의 EXT2 파일 시스템에 저널링 기능이 추가된 파일 시스템이다. EXT3 파일 시스템은 매우 안정적이고, 기존의 EXT2 파일 시스템에서의 변경 과정이 쉽고 간단하여 일반적으로 많이 사용 되고 있는 저널링 파일 시스템이다. EXT3 파일 시스템은 기본적으로 ordered mode 를 사용하는데 메타데이터가 저널에 기록되는 추가적인 과정이 이루어져야 하기 때문에 성능의 저하가 발생한다. 본 논문에서는 ordered mode 에 압축 저장 기법을 적용하여 효율적인 공간 관리와 쓰기 속도가 향상된 ordered mode 저널링 기능을 제안하여 파일 시스템 기능을 개선하고자 한다.

Large-scale and complex disasters have frequently occurred all over the world recently, and they are repeated every year. Accordingly, the need for the systematic management and utilization of raw-data and processing information in the past has increased. For this purpose, this study proposed a construction strategy for disaster and safety record information resources archives based on automatic acquisition, which can be used as a hub for disaster and safety information. Based on local and foreign case studies, several consideration factors for building the archives are determined. Finally, this study proposed four steps for constructing the archives. These are as follows: 1) complete enumeration survey of the disaster and safety record information resources, 2) automatic acquisition possibility study, 3) selection of the resources for preservation, and 4) automatic acquisition of metadata. The construction of the archives proposed in this study will facilitate integrated management, sharing, and use of scattered information resources on disaster and safety.

This study attempted to propose a faceted search function to supplement metadata for existing presidential gifts. To this end, based on 3,574 presidential gifts provided online by the Presidential Archives, identified the characteristics of records extracted from the gift name, gift giver, gift country, gift date, and receipt process, specifications, and characteristics of the presidential gift. Based on this, study designed a facet-based classification of presidential gifts with 5 basic facets and 51 sub-facets and structured facets define each facet element and assign an arrangement order and symbol. This classification system can be expected to be utilized as a basis for building faceted navigation by applying it to a search system. Through the study, it was confirmed that it was necessary to develop a new classification system for presidential gifts, and it was proposed to apply facet classification as an alternative classification system for this purpose.

With the increase in private and community archives to record various different shapes and forms of societies, the establishment of archives for social minorities has heightened. In line with these changes, this study analyzed the Korean queer archives "Queerarch," which focus on records and archives on sexual minorities. This study examined the current status of the archives of Queerarch, and grasped the characteristics of the queer archives and the problems of archival description elements. The current archival description elements used in Queerarch do not fully reflect the characteristics of the queer archives and the multilayer description method. To solve these problems, this study proposed a metadata schema that includes archival description elements that are based on archival description standards such as the General International Standard Archival Description (ISAD (G)), Manual of Archival Description (MAD), Rules for Archival Description (RAD), and others.

Those days when people used paper to make up and manage all kinds of documents in the process of their jobs are gone now. Today electronic types of documents have replaced paper. Unlike paper documents, electronic ones contribute to the maximum job efficiency with their convenience in production and storage. But they too have some disadvantages; it's difficult to distinguish originals and copies like paper documents; it's not easy to examine if there is a change or damage to the documents; they are also prone to alteration and damage by the external influences in the electronic environment; and electronic documents require enormous amounts of workforce and costs for immediate measures to be taken according to the changes to the S/W and H/W environment. Despite all those weaknesses, however, electronic documents increasingly account for more percentage in the current job environment thanks to their job convenience and efficiency of production costs. Both the government and private sector have made efforts to come up with plans to maximize their advantages and minimize their risks at the same time. One of the methods is the Authorized Retention Center which is described in the study. There are a couple of prerequisites for its smooth operation; they should guarantee the legal validity of electronic documents in the administrative aspects and first secure the reliability and authenticity of electronic documents in the technological aspects. Responding to those needs, the Ministry of Commerce, Industry and Energy and the Korea Institute for Electronic Commerce, which were the two main bodies to drive the Authorized Retention Center project, revised the Electronic Commerce Act and supplemented the provisions to guarantee the legal validity of electronic documents in 2005 and conducted researches on the ways to preserve electronic documents for a long term and secure their reliability, which had been demanded by the users of the center, in 2006. In an attempt to fulfill those goals of the Authorized Retention Center, this study researched technical standard for electronic record information package of the center and applied the ISO 14721 information package model that's the standard for the long-term preservation of digital data. It also suggested a process to produce and manage information package so that there would be the SIP, AIP and DIP metadata features for the production, preservation, and utilization by users points of electronic documents and they could be implemented according to the center's policies. Based on the previous study, the study introduced the flow charts among the production and progress process, application methods and packages of technical standard for electronic record information package at the center and suggested some issues that should be consistently researched in the field of records management based on the results.

This study aimed to examine the perception and experience of researchers in the field of mechanical engineering on research data creation and management, and suggest implications for research data management and services in the field. Research data management and services of domestic and foreign research institutes were investigated, and in-depth interviews were conducted with researchers belonging to domestic mechanical engineering research institutes to analyze the perception and conduction of research data creation and management according to four major categories: "research data, accountable conducting of research and compliance with research ethics, utility and effectiveness of research data management, and the value of sharing research data." To ensure effective research data management and services in mechanical engineering, it is necessary to conduct a data investigation on the process, type, and form of production to collect explicit metadata and implicit contextual information. It is also necessary to propose a plan to recognize research results using the publication of data journals and to prepare infrastructure such as a cloud-based system that supports safe data management and communication between researchers. In addition, it suggests that it is important for various officials in the research field to allocate roles and responsibilities for research data management and services at the organizational level.

The integrated management of community archives, which is conducted by incorporating them into the category of library data through the system of library materials management is more necessary for residents to use community archives by arranging and preserving them collected by public libraries, than management implemented through a separate system. This study therefore draw25 descriptive factors by comparatively analyzing descriptive factors of the descriptive standards for community archives such as ISAD(G) and DC, etc. and integrating common or similar ones. Such 25 drawn descriptive factors were empirically tested three times by professionals through the Delphi technique, and 3 descriptive sectors and 21 descriptive factors were finally drawn. The drawn descriptive factors were divided into mandatory, mandatory if applicable and optional through KORMARC-integrated format for bibliographic data and mapping and applied to the system of library materials management, by adjusting the descriptive factors for the systems.

본 논문은 NAND 플래시 메모리를 기반으로 한 임베디드 시스템에서 빠른 부팅을 지원하는 파일 시스템을 제안한다. 플래시 메모리는 비휘발성이며 기존의 하드디스크와 같은 자기 매체에 비해서 크기가 작고 전력소모도 적으며 내구성이 높은 장점을 지니고 있다. 그러나 제자리 덮어쓰기가 불가능하고 지움 연산단위가 쓰기 연산 단위보다 크다. 또한 지움 연산 획수가 제한되는 단점이 있다. 이러한 특성 때문에 기존의 파일 시스템들은 갱신 연산 발생 시, 갱신된 데이터를 다른 위치에 기록한다. 따라서 마운팅 시, 최신의 데이터를 얻기 위해 전체 플래시 메모리 공간을 읽어야만 한다. 이러한 파일 시스템의 마운팅 과정은 전체 시스템의 부팅 시간을 지연시킨다. 본 논문은 임베디드 시스템에서 빠른 부팅을 제공할 수 있는 NAND 플래시 메모리 파일 시스템의 구조를 제안한다. 제안된 시스템은 플래시 메모리 이미지 정보와 메타 데이터 블록만을 읽어 파일 시스템을 구축한다. 메타 데이터가 데이터 위치를 포함하기 때문에 마운팅 시, 전체 플래시 메모리 영역을 읽을 필요가 없으며 파일 데이터 위치 저장을 위한 별도의 자료 구조를 RAM 상에 유지할 필요가 없다. 실험 결과, YAFFS에 비해 $76%{\sim}85%$ 마운팅 시간은 감소시켰다. 또한 YAFFS에 비해 $64%{\sim}75%$ RAM 사용량을 감소시켰다.

In recent time, archival science has been in charge of positively preserving and handling with valuable things, as well as managing established ones, However, even though several archival methodologies that manage contexts among tasks, organizations and subjects exist nowadays, there is a lack of theoretical methodology on archiving focusing on valuable things. In this sense, this article dealt with a theoretical methodology which carries out archiving valuable things and represents it based on the value of records. Also, this paper, which covers a methodology that carries out archiving and representing one focusing on the value of the one to preserve, is divided into three chapters: putting in, managing, and viewing. To begin with, in the chapter of purring in, the methodology of documentation based on a strategy to distinguish and represent the value of the valuable things were explained. In addition, the article tried to explain the definition of how the valuable things based on the value of it can be put in, and presented how to divide the one for representation into the objet and the activity so as to provide an effective approach. At the same time, as this paper took an approach to the value of the one, it proposed a way to be able to do archiving effectively by applying a representation unit which has its own value. Secondly, in the chapter of managing, representation class and metadata for managing with a representable structure was considered. Metadata categories were illustrated in order to present the class from individual records to final representation valuable things and to make representation with ease. Furthermore, in the chapter of viewing, the process of representation using theoretically archived records was explained. In fact, viewing is the descriptive domain in general, yet this paper focused on the conceptional part. As a consequence, in this paper, a series of process was considered, which starts from how the subject of representation was archived to managing it. Moreover, the process has a meaning by itself in that it gives a practical method to be applied. Finally, the paper suggested that the argumentation on representation be expanded in the field of archival science so as to present theoretical grounds in this sort of work.

The National Assembly Archives of the Republic of Korea has been using the National Assembly Archives and Records Management System, which added some archival function to the Standard Records Management System that they had previously developed. However, the Standard Records Management System has limits in order to reflect all the business functions of the National Assembly Archives, which also acts as an archival institution, because the system had been developed and distributed to perform the function of a records center. Moreover, the current National Assembly Archives and Records Management System focuses on the management of official records transferred in accordance with the regulations. For this reason, it is difficult to register and manage various record types such as records of the members of the National Assembly (related to legislative activities), oral history collected from the National Assembly leader, audiovisual records of proceedings, and so on. As such, this study analyzed the problems of the current National Assembly Archives and Records Management System and conducted case studies of the systems in the National Archives, the Presidential Archives, Changwon City, and the Cultural Heritage Administration. Through this research, it proposed that system functions, metadata, the target system of the National Assembly Archives, and the Records Integrated Management System need a development plan.
