Big data has a key engine of the new value creation and troubleshooting are becoming more data-centric era begins in earnest. This paper takes advantage of the big data, big data in order to secure the quality of the quality elements for ensuring the quality of Justice and quality per-element strategy argue against. To achieve this, big data, case studies, resources of the big data plan and the elements of knowledge, analytical skills and big data processing technology, and more. This defines the quality of big data and quality, quality strategy. The quality of the data is secured by big companies from the large amounts of data through the data reinterpreted in big corporate competitiveness and to extract data for various strategies.

Increasing the value of data, paradigm shifts in research methods, and specific manifestations of open science indicate that research is no longer text-centric, but data-driven. In this study, we analyzed the services for DCC, ICPSR, ANDS and DataONE to derive key elements and functional requirements for research data management and services that are still insufficient in domestic research. Key factors derived include DMP writing support, data description, data storage, data sharing and access, data citations, and data management training. In addition, by presenting functional requirements to the derived key elements, this study can be applied to construct and operate RDM service in the future.

The purpose of this study is to build a metadata set based on the semantic structure of the humanities field research articles for research data that can associate research data and research articles. To understand the interest of Humanities researchers, keywords of research articles were categorized. By proceeding the keywords classification and analyzing based on the semantic structure of general research papers, additional elements to be added were identified for reflecting the characteristics of the humanities field. Based on it, 17 metadata elements based on the semantic structure of research papers in the humanities field was determined. In order to evaluate whether the metadata is appropriate as a metadata for research data in the humanities field, a survey was conducted on researchers in the humanities field. As a result of the survey, 7 elements were judged to be suitable for use as metadata for research data in the field of humanities, and 10 other elements were identified as usable elements. Drawing on the survey results, the metadata based on the semantic structure of the humanities field research articles for research data was constructed.

Advances in VLSI technology have made it possible to have a larger number of processing elements to be included in highly parallel processor system. A system with a large number of processing elements and memory requires a complex data path. Multistage Interconnection networks(MINS) are useful in providing programmable data path between processing elements and memory modules in multiprocessor system. In this thesis, the performance of MINS for the star network has been analyzed and compared with other networks, such as generalized shuffle network, delta network, and referenced crossbar network.

In 1607, Matteo Ricci and Xu Guangqi translated Euclid's 《Elements》 and published 《Jihe yuanben, 幾何原本》. Though 《Elements》 consists of 13 volumes (or 15 volumes according to its editions), they translated only the first 6 volumes on the plane geometry. Why did they do so? This paper discusses about the three questions which naturally arise: What might be the motive of the translation of the 《Elements》? What method did they adopt for the translation? And why did they translate the 6 volumes, especially, the first 6 volumes, not completing the whole?

Sharing of CAD data plays a key role in the PLM and a lightweight model is widely used for visualizing and sharing a large data. The lightweight model is mainly composed of triangular elements to minimize file size. There is no problem at all to visually confirm the shape based on these triangular elements but there is a limit to numerically calculate the exact position on the curve or surface. In this paper, a boundary curve generation method using triangular elements is proposed to increase the utilization of lightweight models. After matching connectivity of triangular elements, boundary element edges are extracted. Boundary curves are generated by connecting of these boundary element edges. This proposed method has been tested on several models to demonstrate the feasibility.

Shell finite elements are widely used for the analysis of thin section objects such as sheet metal parts, automobile bodies and et al. due to their computational efficiency. Since many of input data for finite element analysis are given as solid models or triangulated surface models, one should extract midsurface information from these input data initially and then construct shell meshes on the extracted midsurfaces. In this paper, a method of generating shell elements on midsurfaces directly from input models have been proposed. In order to construct shell meshes, the input models should be triangulated on surfaces first, and then tetrahedral elements are generated by using an advancing front method, and finally mid shell surfaces are obtained from tetrahedral meshes. Some examples are given to demonstrate the efficiency of the proposed method.

Cultural assets are subject to general elements of deterioration due to aging of materials and surrounding conditions over time and these elements do not influence structural safety. However, wood cracking(penetrative), disparity of joints, deformation of structure, damage by insects and ground subsidence as the elements of structural deterioration as well as slanting of building structure caused by composite elements exert serious impact on safety of cultural assets. Therefore, repair must be administered by deciding the appropriate time and investigating the status. However, there are no grounds for making such decisions because investigative data on cultural assets have not been organized analyzed and the results of investigation have not been established as database. There is also lack of objectified bases. Therefore, this study aimed to investigate organize elements of structural deterioration with reference to cultural assets of building structures in Seoul so that to use the results found as the basic data for preservation of cultural assets.

In this paper, the degree of reflection of SW·AI elements and CT elements was investigated and analyzed for a total of 44 textbooks of Korean, social, moral, mathematics and science textbooks based on the 2015 revised curriculum. As a result of the analysis, most of the activities of data collection, data analysis, and data presentation, which are ICT elements, were not reflected, and algorithm and programming elements were not reflected among SW·AI content elements, and there were no abstraction, automation, and generalization elements among CT elements. Therefore, in order to effectively implement SW·AI convergence education in elementary school subjects, we will expand ICT utilization activities to SW·AI utilization activities. Training on the understanding of SW·AI convergence education and improvement of teaching and learning methods using SW·AI is needed for teachers. In addition, it is necessary to establish an information curriculum and secure separate class hours for substantial SW·AI education.

The purpose of this study is to present technical elements to improve the data utilization of the ISNI Korea Consortium, which is operated by the National Library of Korea, which is responsible for the registration of Korean names. The ISNI Korea Consortium aims to register various creation-related information in addition to bibliographic-related individual and organization name information. To this end, this study examines the ISNI Korea consortium, which is a data provider's consultative body, among other things, the metadata status of copyright organizations and the linked data specification of ISNI. As a result, data acquisition, refining, storage, identifier management, consortium metadata management, five in total, and RDF data management (repository) in terms of linked data, RDF data issuance, RDF data retrieval, RDF data inquiry, RDF data Eight technical elements, including download, ontology inquiry, standard term inquiry and mapping information management, were derived.
