Foresight, a major methodological tool in the STI policy toolbox, has recently featured new directions in methodological development, becoming influenced by progress in information and communication technologies and online tools. However, no overview of these directions has been available so far. Based on a literature review, an interactive workshop, and an international expert survey as well as expert interviews, the research presented here attempts to shed light onto some of the relevant issues by providing a structured overview of recent changes in order to further the debate on the future directions of methodological development in foresight. The paper outlines four clusters of emerging approaches in foresight:Integrated qualitative and quantitative approaches, IT-based and automated foresight, experiential foresight including new forms of communication and interaction such as visualization and gaming, and open and crowd-sourced approaches. The benefits and challenges of the approaches known so far are categorized and summarized, and areas of potential use for each of the clusters in STI contexts are identified.

The purpose of this study was to evaluate a group activity, reciprocal peer tutoring (RPT), in order to investigate advantages and challenges of RPT in promoting cooperative and collaborative learning environment for EFL University reading instruction. The participants in this study were 89 students taking an English reading course at a Korean university. RPT is a learning strategy whereby learners help each other and learn by teaching. This program was supported by a Vygotskyan perspective which assumes that learners gain mastery and develop cognitive skills through social interaction with more proficient others and their environment. This study relied particularly on participant perceptions through questionnaire survey and Anonymous Online class Report of the course. This study showed various advantages for tutors such as learning through teaching and becoming more autonomous and responsible for their own learning. Non-threatening and highly motivating learning atmosphere are parts of benefits for tutees. Other advantages for tutees included improved level of academic self-confidence, and motivation. This study also revealed several drawbacks associated with the problem of inaccuracy in students' production and students' demand for more direct teacher role. (182 words).

The concept of an "intelligent building" received significant attention from academic, industry and standard development organizations when technically termed a building management system (BMS). Wireless sensor networks (WSNs) and their recent development enhanced monitoring and control applications for the building's areas. This paper surveys and analyzes advantages of the main current and emerging approaches that may be fit for BMS. Specifically, we discuss challenges including interoperability, integration, overhead, and bandwidth limitation of WSNs in BMS. Based on analyses, we highlight the advantages of an IP-based and RESTful architecture approach as the most suitable solution for BMS using WSNs (BMS-WSN). The paper also describes our future direction and design for BMS-WSN based on these advantages. The purpose is to enable interaction of users with BMS-WSN in the same way as with any website while ensuring energy efficiency. A test-bed implementation and evaluation of a BMS application is also introduced in this paper to demonstrate the feasibility and benefits of IP-based and RESTful architecture for BMS.

일반적으로 공공시설에 대한 지정관리자제도 도입은 운영관리의 예산삭감과 민간에 의한 이용자 서비스 향상을 도모하기 위한 행정개혁의 일환으로 추진되고 있다. 일본의 경우 2006년부터 본격적으로 공공마리나시설에 지정관리자제도가 도입되기 시작하였으며 경제적 측면(예산절감)에서의 효율성에 대해서는 긍정적 평가를 받고 있다. 하지만 주된 업무가 서비스인 마리나에 있어 이용자 측면의 서비스 만족 등 효율성에 대한 논의는 전무하다. 따라서 본 논문의 목적은 첫째 일본의 지방자치단체법 개정에 의해 실행된 지정관리자제도(Designated Manager System, 이하 DMS)를 도입한 마리나의 현황을 파악하여 이점과 문제점을 도출한다. 둘째 공공마리나 시설 이용자의 관점에서 DMS 도입 전과 후의 이용자 서비스에 대해 비교조사를 실시한다. 첫 번째 목적에서 본 연구에서는 DMS의 경제적 이점과 지방자치단체 레벨에서 DMS의 중요성을 명확히 하였다. 이것은 DMS를 도입하여 공공시설 운영 및 관리에 참여하려는 민간 사업자, NPO에게 도움이 될 것이다. 또한 지금까지의 대부분의 연구는 DMS를 도입한 지방자치단체의 경제적 경비절감에만 중점을 두고 있었다. 따라서 본 연구에서는 이용자의 관점에서 DMS의 이점과 문제점을 밝혀내었으며 이것을 바탕으로 DMS를 도입한 마리나 시설의 운영 방향에 대해 검토하였다.

Global e-SCM (electronic Supply Chain Management) has become an important business strategy in a rapidly changing global competition environment. It encompasses both domestic business and overseas business. Overseas business, including B2B and B2G, involves the complex trade procedures across countries. So, the standardization of electronic documents (messages) and business processes is one of critical factors for the successful implementation of global e-SCM. Without standardized messages and streamlined business processes, the benefits of global e-SCM would not be guaranteed because of human intervention like re-keying business data, which may create errors, delay processes, cause additional data or procedures, etc. Thus, this paper is to review the implementation challenges of Global e-SCM, to address the needs for electronic information flows through the standardization in electronic documents and business processes for fast and accurate trade transactions in the global supply chain activities, and to assert the importance of adoption of international standards.

The rich cultural backgrounds and practices of children from native cultures are often absent in classroom instruction, as teachers might feel that they have inadequate knowledge and backgrounds in the unique practices of these populations. Historically, children from native cultures have had challenging educational experiences and poor educational outcomes. To address these challenges, we propose a Family and Culture Based (FCB) framework that draws from family-centered practice, asset-based practice, and culturally responsive pedagogy. This article describes the three steps of the FCB framework, which uses a teacher-as-learner approach to instruct students from native cultures by engaging teachers in reflection, gaining knowledge about the cultural practices of the family and community, and integrating the new knowledge into practice. We use a Pacific Islands case (Native Hawaiian family) and a Pacific Northwest case (First Nations family) to illustrate the potential benefits of using the FCB framework with indigenous students.

National Health Insurance Service (NHIS) has put a great effort on extending life expectancy, for last 40 years. The system has also made remarkable outcomes in achieving universal health coverage. However, it is facing challenges of low health insurance benefits and sustainability risk due to low birth rate and aging society at the same time. To overcome the difficulties and build a lifelong health security system for the nation, it is required for NHIS to make multilateral changes in its roles. Based on the quantitative growth achieved so far, NHIS needs to strive for the growth in quality by not only increasing coverage and reforming contribution imposition system, but also reorganizing the relevant systems such as lifelong health management support, rational adjustment to the medical fee, and benefit costs monitoring. In addition, it's important for NHIS to restructure the organizational culture by having specialty and communicating with people for high quality of administration and health insurance sustainability.
