The information system fields of spatial applications have rapidly grown during the last decade in Korea. Spatial data has been produced for a variety of systems without common standards until national GIS Committee defined the data exchange formats among spatial databases in the middle of 1990's. It aimed at promoting data sharing between the different systems in similar application fields. However, a considerable number of databases built prior to the introduction of the standards are not yet standard compliant but still play the roles of the main producers/consumers in the data collection field such as early developed huge AM/FM systems maintained by governmental organizations. The strong autonomy of these databases keeps their own data models, formats and descriptions from being standardized, which leads the sharing to a more difficult stage. Sharing is another way of data acquisition with least efforts and time away from direct collection. A data clearinghouse is the core module which directs users to the relevant data resources. The contents of datasets should be described with predefined metadata standards for precise indexing. Moreover, a number of technical problems have to be resolved for the common use of data between heterogeneous spatial database systems. However, the technical issues can be covered by the present information technologies. The difficulties persist in the political/institutional issues. Institutional issues are derived from the diverse sources such as political background, governmental policies, related laws and/or regulations. The paper will firstly make an analysis of current situation in terms of Korean policies, laws and regulations, secondly abstract the institutional issues from the situation analysis, lastly present guidelines for promoting spatial data sharing in Korea.

The standard metadata systems are very popular for the description of structures and semantics of information resources to realize sharing and exchanging information in global ubiquitous environment. In real application domain, various metadata elements are reused together with mix-and-match manner. An application system using diverse metadata systems is compelled with refinement and interoperability of metadata elements. Application profile is the general approach to resolve the various problems occurred in metadata application systems. This paper proposes Application Profile Core Ontology (APO) that can achieve the goals and functions of application profile, and describes metadata application system based on APO.

This study clarifies the definition of and to provides guidelines on educational objectives, core concepts, and content in developing a Human Rights Education Program for families. The Delphi survey method was used to develop a Human Rights Education Program for families. As a result, a Human Rights Education Program for families was defined as education that would ensure all members of the family enjoy universal human rights without discrimination. In addition, that the prejudice and discrimination against socially marginalized would not be created within the family by learning values and attitudes that respects human rights and freedom. The objectives were to learn the merit of respecting individuals, relationships, and community. Core concepts of the program were the rights for myself and others, communicating and responsibilities and a sense of citizenship. Content included human rights, respect of oneself and others, empathetic understanding, acceptance, communication in an intimate relationship, conflict management, sharing the role of caring the family, no discrimination against the socially marginalized, and creating an inclusive community culture. This study can be used as a guideline for family human rights education based on family human rights, which is the core of family democracy.

This study proposes a performance improvement for parallel-connected thyristor dual converters using a circulating current with an unbalanced parallel operation compensator. The proposed control method determines a variable reference value for the voltage PI controller according to voltage error at firing angle control applied to a difference current control. This method uses circulating current control to maintain a stable voltage and excellent current response during parallel operation. The effectiveness of the proposed control is verified with a simulation and an experiment based on the comparison of the performance of the proposed control method with other conventional methods.

With the recent increase in interest in the open science movement in science and technology fields such as open access, open data, and open source, the movement to share and utilize publicly funded research products is materializing and revitalizing. In line with this trend, many efforts are being made to establish and revitalize a system for sharing and utilizing research data, which is a key resource for research in Korea. These efforts are mainly focused on collecting research data by field and institution, and linking it with DataON, a national research data platform, to search and utilize it. However, developed countries are building a system that can share and utilize not only such research data but also various types of R&D-related computing resources such as IaaS, PaaS, SaaS, and MLaaS. EOSC (European Open Science Cloud), ARDC (Australian Research Data Commons), and CSTCloud (China S&T Cloud) are representative examples. In Korea, the Korea Research Data Commons (KRDC) is designed and a core framework is being developed to facilitate the sharing of these computing resources. In this study, the necessity, concept, composition, and future plans of KRDC are introduced.
