The importance of long-term preservation of various types of electronic records through dark archives is gradually increasing. However, the current dark archive does not have an optimized information package structure for long-term preservation of electronic records. In order to address these problems, this research proposed four element categories by re-organizing the OAIS reference model information package based on the core process of the dark archiving. The detailed descriptive items of each category consist of a total of 4 upper-level elements and 27 sub elements based on the OAIS reference model, ISO 23081, Records Management Metadata Standard, ISAD(G), ISAAR(CPF), ISDF, and ISDIAH. This structure can be used as a basis for constructing an information package optimized for dark archiving, and is expected to support the long-term preservation of electronic records more efficiently.

In this study, description elements of National Archives of Korea(NAK) and National Assembly Archives(NAA) were collected and analysed based on PDI(Preservation Description Information) of OAIS Reference Model(ISO 14721). As for NAK, records management guideline published in 2009 and metadata standards published in 2007 were analysed. As for NAA, Records management manual published in 2009 and metadata applied in national assembly records management system were analysed with group interviews. As a result, improved metadata details and sub-elements were suggested based on OAIS PDI concepts and Calanag's and Russell's research.

The purpose of this study is to propose a scholarly paper recommendation system based on metadata attribute similarity with excellent performance. This study suggests a scholarly paper recommendation method that combines techniques from two sub-fields of Library and Information Science, namely metadata use in Information Organization and co-citation analysis, author bibliographic coupling, co-occurrence frequency, and cosine similarity in Bibliometrics. To conduct experiments, a total of 9,643 paper metadata related to "inequality" and "divide" were collected and refined to derive relative coordinate values between author, keyword, and title attributes using cosine similarity. The study then conducted experiments to select weight conditions and dimension numbers that resulted in a good performance. The results were presented and evaluated by users, and based on this, the study conducted discussions centered on the research questions through reference node and recommendation combination characteristic analysis, conjoint analysis, and results from comparative analysis. Overall, the study showed that the performance was excellent when author-related attributes were used alone or in combination with title-related attributes. If the technique proposed in this study is utilized and a wide range of samples are secured, it could help improve the performance of recommendation techniques not only in the field of literature recommendation in information services but also in various other fields in society.

Recently, as the dissemination of the Internet and development of computer network technology, Research is actively underway for realization of the next-generation computing paradigm called Ubiquitous Computing. For realization of Ubiquitous computing, The data recognized from each sensors must be collected on real-time and transferred to applied service so that they may be used as data for providing service to users. However, there are several problem for realization. First, there is no standardization of sensor metadata, interface and event definition. Second, applied service has weak point that difficult of approaching to the data. Third, none interoperability with each platform and protocol. In this paper, we designed Sensor Service Description Language based on XML to resolve problem above. This Language expresses the measurement of the sensor and Service Metadata in the form to be standardized. In addition, we have proposed and development a reference model for USN application service.

Inundation Maps are used to predict potential areas of flooding through the signs of past flooding and flood inundation analysis for flooding expected in the future, and this has led to the development of various forms of disaster-related services by governments. However, each institution has its own individual scenarios for making maps for spatial expression. Therefore, the type of spatial information is not standardized and has many forms and structures. In this study, we attempted to design the metadata that would allow Inundation Map information to be shared and used in various fields. The international standard, ISO 19115, and the domestic standards, KS X ISO 19115, TTAS.IS - 19115 and TTAS.KO - 10.0139/R1 of TTA, were used in the design to derive an appropriate standard for comparative analysis by dividing into maintenance, constraints, metadata, spatial reference system, identification, and distribution. It is expected that inundation maps will be easier to utilize and distribute among institutions and private companies by systematically collecting and managing them through the metadata design based vector space information standard developed in this study.

In the field of defense M&S, we are actively pursuing researches that interoperable multiple war game models to simulate various combat environments at the same time. Although the 'unit DB(Database)' for operating the war game models is originated from the identical data, it has been recognized that the method of expressing the attribute of the data is different and the cross reference is impossible. As a result, it makes unnecessary time and effort in establishing the same unit DB in the organizations that operate the war game model. In this study, a method of reusing the unit DB of the training war game model to the analysis war game model with similar resolution and simulated logic was applied to the actual field. For this purpose, we defined the procedure for converting the unit DB by analyzing metadata of the 'Chang-Jo21', a combat training model for corps and division, and the 'Vision21', an analysis model for corps and division operation plan. And we introduced an algorithm that can map different metadata of two unit DBs. This study was meaningful as the first attempt to map and integrate heterogeneous metadata semantically for the reuse of unit DB between different war game models in defense M&S field. Also, it provided implications for the necessity of paradigm shift that reuse of the unit DB between two different war game models is possible and the need for standardization of the unit DB metadata in the defense M&S filed.

R&D Personnel information is constructed locally based on the needs of each institute and therefore is distributed over different databases. It does not support inter operability which makes it difficult to access and update that leads to the problem of ineffective usage. In this study, we have categorized the lower level information that forms the domestic S&T Personnel and defined the relationship between each type of information to suggest a standard for the data elements that guarantee the access to specific information in order to support inter operability. We have analyzed the human resource information database of domestic and foreign research institutes for the data modeling. We have also made reference to the standard metadata and database of other types that can be linked with the human resource information in designing the data elements. ISO/IEC 11179, the international standard for the metadata registry(MDR), was adopted to apply the object, attribute and expression to be described to the name of the data element.

In this study, a system to increase the expressiveness of existing standard terminology using three-dimensional (3D) data is designed. We analyze the existing medical terminology system by searching the reference literature and perform an expert group focus survey. A human body image is generated using a 3D modeling tool. Then, the anatomical position of the human body is mapped to the 3D coordinates' identification (ID) and metadata. We define the term to represent the 3D human body position in a total of 12 categories, including semantic terminology entity and semantic disorder. The Blender and 3ds Max programs are used to create the 3D model from medical imaging data. The generated 3D human body model is expressed by the ID of the coordinate type (x, y, and z axes) based on the anatomical position and mapped to the semantic entity including the meaning. We propose a system of standard terminology enabling integration and utilization of the 3D human body model, coordinates (ID), and metadata. In the future, through cooperation with the Electronic Health Record system, we will contribute to clinical research to generate higher-quality big data.

The current technological revolution pushes forward the innovation in the library information systems. This study proposes functional requirements and an architectural reference model of Semantic Library, recognized as a prototype of next-generation library information systems, that is a seamless convergence of the library information systems and the Internet technologies. Semantic Library can realize semantic interoperability and integration based on ontology and metadata, and also renovate information services for users with openness, sharing, participation and collaboration. Semantic Library will be effectively implemented by means of service-oriented architecture and the logical structure of FRBR. In this study, a reference model of Semantic Library consisting of 6 horizontal layers and 3 vertical elements is presented as a next-generation model of library information systems.
