사례기반학습을 통한 유아교사의 놀이 개입유형 변화경험 탐색
장은정(Jang EunJung),유영의(Yoo YungEui) 학습자중심교과교육학회 2020 학습자중심교과교육연구 Vol.20 No.5
본 연구는 사례기반학습을 통한 유아교사의 놀이 개입유형의 변화를 알아보는 것이다. 이를 위하여 B어린이집 만 4세반 담임교사 2명을 연구 참여자로 선정하였으며, 2018년 11월부터 2019년 11월까지 사례기반학습 설계, 예비연구, 연구 참여교사 선정 및 현장 방문, 사례기반학습 실행의 4단계로 연구를 진행하였다. 연구 참여교사의 놀이 개입유형의 변화를 알아보고자 교사들이 담당하고 있는 하늘 1, 2반의 자유놀이시간을 연구자가 비참여 관찰하였고, 참여관찰, 면담, 토의노트 및 저널, 사례기반학습 토의과정을 토대로 자료를 수집하여 분석하였다. 그 결과 사례기반학습을 통한 유아교사의 놀이 개입유형 변화는 놀이를 민감하게 관찰하고 반응하는 방관자 개입유형으로 변화하기, 놀이 환경을 풍부하게 제공해주는 무대관리자 개입유형으로 변화하기, 유아의 의견을 수용하며 놀이를 공동구성하는 공동놀이자 개입유형으로 변화하기, 유아주도의 놀이가 지속될 수 있도록 놀이를 안내하는 놀이지도자 개입유형으로 변화하기, 지시보다는 효율적으로 놀이를 제안하는 감독 및 방향전환자 개입유형으로 변화하기가 나타났다. The aim of this study was to investigate early childhood teachers’ changes in play intervention type through case-based learning. To this end, two homeroom teachers of 4-year-old class at B child care center were selected as the research participants. From November 2018 to November 2019, the research was conducted in four stages: case-based learning design, preliminary research, selection of participating teachers and field visits, and implementation of case-based learning. In order to investigate the participating teachers’ changes in play involvement type, the researcher conducted a non-participatory observation. Data were collected from and analyzed based on observation notes, interviews, discussion notes and journals, and case-based learning discussion process. As a result, it was found that early childhood teachers show the following changes in play intervention type: changes to a bystander who observes and responses sensitively to play, a stage manager who provides rich play environment, a co-player who accepts the opinions of young children jointly and organizes play, a play leader who guides play so that child-initiated play is sustained, and a director and redirector who efficiently suggests play rather than giving instructions

This study was designed to develop multilateral STI (Science, Technology and Innovation) cooperation strategies in response to the global shocks that we are currently experiencing and that may arise in the future. To this end, this paper first investigated the development of multilateral STI cooperation centered on the United Nations system (UN system), and then surveyed UN system’s response to global shocks such as COVID-19. The key findings of this study are summarized as follows. First, STI cooperation in the UN system has been continuously promoted as a means of achieving international security and development since the establishment of the UN. Security-related STI cooperation has been mainly discussed at the Security Council and the UN General Assembly, and the Related Agencies, such as IAEA, CTBTO, and OPCW, have been also playing a key role. Moreover, STI cooperation for development has been heavily discussed at the Economic and Social Council including CSTD and ESCAP, and Specialized Agencies such as ITU, UPU, IMO, WMO, UNESCO, WIPO, and WHO have also played a significant role for STI cooperation. Furthermore, policy agendas related to innovation, sustainable development, and digital technology have been increasingly emphasized for STI cooperation within the UN system these days. Recently developed organizations, such as the Technology Facilitation Mechanism (TFM) for Sustainable Development, and UNFCCC, are dealing with these emerging needs for STI cooperation. Second, the United Nations system has evolved to respond to global shocks. It has broadened the scope of cooperation in response not only to global security risk but also to economic and financial crises. It has further developed multi-lateral cooperation schemes to cope with various environmental emergencies as well as health emergencies. In particular, the UN system has devised and delivered immediate and comprehensive emergency responses in the amid of the recent COVID-19 pandemic. From the beginning of the outbreak, it defined COVID-19 as a complex crises that combine not only health issues but also socio-economic and humanitarian threats and strived to take comprehensive measures. In this process, the following needs for STI cooperation were identified and met: 1) joint research and R&D collaboration for scientific solutions to COVID-19 (treatment, diagnosis, vaccine, and prevention measures), 2) research data and resource sharing for accelerating R&D, 3) digital technology-based assistance to overcome crises, and 4) global consultation and communication based on reliable scientific information and knowledge. The occurrence of global shocks has led to new development of science-policy interfaces in the UN system. In order to fully utilize the newly created STI cooperation opportunities in emergencies, this study proposes to (1) support more STI experts to get engaged in UN cooperation process, (2) increase Korea’s contribution to global joint research and technology cooperation that directly tackle global crises, (3) actively participate in the UN’s system coordination activities and digital cooperation initiatives, and (4) to propose and lead a future STI cooperation agenda, such as crisis response based on future foresight. Furthermore, it is recommended to continuously strengthen Korea’s existing activities for STI cooperation in the UN system. Lastly, although not fully addressed in this study, STI cooperation beyond the UN system is so important that requires further research.
Development of additives for DME as a renewable energy

DME is generally expected to be used as a promising clean alternative fuel to diesel fuel. DME is not natural product but a synthetic product that is produced either through the dehydration of methanol or a direct synthetic from syngas. As DME has no carbon-carbon bond in its molecular structure and is an oxygenate fuel, it's combustion essentially generates no soot. DME has such cetane number of 55~60 that it can be used as a diesel engine fuel. However, DME has low lubricity but a proven method to solve the poor lubricity is by adding lubricity improver. Therefore, the aim of this study is to develop lubricity improver of DME as a transport fuel in Korea. In this study, we investigated a possibility of fatty acid ester compounds as a candidate to improve DME lubricity as compared with current lubricity improver of diesel. We also evaluated quality characteristics, storage stability of DME with lubricity additives.
