As IVAN(International VAN) becomes a major topic on the table of Korea U.S. Telecommunications Consultation, public concern to this area is growing. IVAN service has been dedicated to the business domain of PTT or public telecommunications operator, and its development has been so limited as well. However, the situation is being changed and IVAN liberalization is considered to be essential not to isolate itself from globilized networks. Seeing the fact UR is challengnign ITU in facilitating the trade of telecommunications services, the worldwide trend of liberalization is apparant. It should be addressed that a clear policy anouncement is necessary with regard to the liberalization of IVAN. The purpose of this paper is to conduct case studies of IVAN agreements and to draw policy oriented issues.

This study examines the social problem-solving R&D policies from the perspective of 'Mission-oriented innovation policy'. To this end, we analyzed the 'second science and technology-based social problem solving plan' in terms of civil society's participation, securing the government's dynamic capabilities, and government's risk investments. The plan introduces an institutional framework for civic participation for social problem-solving innovation, strengthening R&D program coordination and integration, and new innovation ecosystem formation. However, there is a need for a concrete program to overcome a path dependency of existing activities. Otherwise new institutions are likely to be formalized. In addition, in order to derive risk investment, it is necessary to integrate innovation policy with social policy fields such as community care and climate change. It is necessary to establish an policy process that combines the agenda of social policy beyond with R & D policy, and to forms a platform for problem solving, integrates various technologies, industries and resources.

This study examined the factors determining experience of flow in mobile social network games. Built upon the literature on flow experience in the Internet and online games, this study classified the determining factors into three categories. The first category is the content factor which includes graphic design, challenge, and incentive; the second is the device factor including ease of access and ease of control; the third is the social factor including social interaction and community activities. A correlation analysis was conducted to examine the association between each of the seven determining factors and flow experience. Additionally, a hierarchical regression analysis was performed to evaluate which of the selected factors would exert a relatively strong influence on experience of flow. Both analyses reached the same conclusions as follows: Graphic design, incentive, and community activities increase flow experience while challenge and ease of control exert little influence on flow experience. In addition, graphic design was the most influential element in determining flow experience, followed by community activities and incentive, respectively.

This study examined the activities of Community of Practice (CoP) of research data curators, including their community building and maintenance activities, by using activity theory as its main theoretical framework. The study used an embedded multiple-case study design for exploring the activities of three CoP of research data curators. The case study design used document analysis and semi-structured interviews to collect data. Besides the community building and maintenance activities, other activities were performed in the CoP of research data curators, which could be largely divided into curation activities, education activities, and communication activities. Membership was largely divided into institutional membership and individual membership, and the motives for members to join and contribute to the CoP vary from extrinsic to intrinsic motivations. Finally, we identified and categorized challenges and success indicators for CoP of research data curators as perceived by participants. In particular, we identified three types of challenges or contradictions the communities faced and 14 perceived indicators of success. This study informs the practice of research data curation by providing a knowledge base for building and maintaining a CoP of research data curators.

This study provides a systematic review of smart trade contracts, examining the research trends and theoretical background of utilizing smart contracts and blockchain technology for the digitalization and automation of trade contracts. Smart trade contracts are a concept that applies the automated contract system based on blockchain to trade-related transactions. The study analyzes the technical and legal challenges and proposes solutions. The technical aspect covers the development of smart contract platforms, scalability and performance improvements of blockchain networks, and security and privacy concerns. The legal aspect addresses the legal enforceability of smart contracts, automatic execution of contract conditions, and the responsibilities and obligations of contract parties. Smart trade contracts have been found to have applications in various industries such as international trade, supply chain management, finance, insurance, and energy, contributing to the ease of trade finance, efficiency of supply chains, and business model innovation. However, challenges remain in terms of legal regulations, interaction with existing legal frameworks, and technological aspects. Further research is needed, including empirical studies, business model innovation, resolution of legal issues, security and privacy considerations, standardization and collaboration, and user experience studies to address these challenges and explore additional aspects of smart trade contracts.

ERP supports the automation and integration of business processes of enterprises and records voluminous data about the business activities of enterprises. The academe and business enterprises are focusing on process mining, which improves the performance of business processes and strengthens compliance. However, these studies focused on analysis of the business process of large companies, which adopts foreign ERP, such as SAP ERP or Oracle ERP. In comparison with foreign ERP, domestic ERP lags behind in terms of logging and managing of event data. Therefore, the application of process mining to domestic ERP is a challenging task. The present study aims to analyze domestic ERP based on process mining to overcome this challenge. This study discusses the lessons learned from a case study in a Korean cosmetics manufacturing company. Our results are expected to strengthen the competitiveness of Korean small and medium-sized enterprises that adopt domestic ERP and realize the outcomes of the large investment of the Korean government on the ERP implementation of enterprises.

신기술의 발전에 대한 예측이 어려운 상황에서 가속력을 가지고 급변하는 경영환경은 새로움을 요구하고 있다. 그 새로움을 누가 어떻게 찾아 실행하는가가 기업의 경쟁력이 된다. 기업들의 경쟁력 강화를 위한 핵심적인 과제는 통제가 아닌 자율권을 부여함으로써 미래를 예측하고 능동적으로 대처하여 창의적인 역량과 능력을 갖춘 인재를 양성하고 관리 하는 것이며 이와 연결되는 개념이 슈퍼리더십이다. 지금 우리의 사회는 첨단 산업과 관련된 4차 산업혁명의 물결과 패러다임의 변화로 인해 창의성과 스피드 경영이 절실하다. 정형화된 환경이 아닌 위험과 도전이 공존하는 시간이다. 기업은 인재관리를 위한 노력과 그들이 현시대에 맞는 리더십을 갖추어 도전할 기회를 마련해 주어야 한다. 특히 새로운 혁명적인 기술이 출현 되고 기존의 기술이 고도화 및 극대화되는 산업 중심 시대에 구성원들의 잠재 능력을 배양해 기업이 경쟁 우위를 확보하고 최고의 경영성과 창출을 위해 슈퍼리더십의 필요성을 강조하고 있다. 이에 본 연구는 중소기업의 슈퍼리더십이 경영성과에 미치는 영향관계를 실증 분석하였다. 연구결과 기업이 지속할 수 있는 경영성과를 창출하기 위해서는 리더십을 개발하고 그에 맞는 인재를 육성하는데 더 많은 투자를 해야 한다. 지금과 같은 무한 경쟁시대에 기업이 지속가능한 성장과 더불어 생존하기 위해서는 조직구성원의 역량 극대화에 노력하고 그들이 몰입하게 하는 강력한 슈퍼리더십 구축이 절실하다고 판단된다.

For preservice teachers' instrumental-to-relational pedagogical content knowledge transformations, this research designed several didactical tasks based on Kinach's cognitive strategies. The researcher identified preservice teachers' understanding about what is a definition and how to teach it. By challenging their fixed ideas about definitions, the researcher could motivate them to embrace the new teaching approach which guides reinvention of definitions. The PCK development was not the simple process of filling their tabular rasa PCK with theories of mathematics education, but the dialectical process of identifying, challenging, changing and extending preservice teachers' existent PCK. This research will contribute to explore new directions of mathematics teachers' PCK development and the method of teacher education.
