The purpose of this study was to develop 'Appropriate Technology' theme STEAM Program for the elementary students and investigate the effects of the program on creative thinking activity, scientific attitude and leadership. Participants were 3grade 85 elementary school students. Before and after the program, the participants were asked to take the tests about creative thinking activity, scientific attitude and leadership. The major results of this study were as follows. First, the total score of experimental group's creative thinking activity and all 4 sub-domains was significantly improved than those of comparative group(p<.05). Second, the total score of experimental groups' scientific attitude was significantly improved than that of comparative group(p<.05). Among 7 sub-domains, curiosity, voluntariness, perseverance were significantly developed. Third, total score of experimental groups' leadership was significantly increased than that of comparative group after the STEAM program (p<.05). In the first factor, the score of inner and inter personal characteristics were significantly developed.

It should be supported by the ease and economic production in terms of appropriate technology to be widely used in the real applying fields. In particular, the diagnosis of diseases is one of the most difficult areas to apply to the developing countries compared to other fields because of the high costs of professional manpower, equipment, and medial reagents. In recent years, paper, which is one of the most common materials around, has been used to fabricate the disease diagnostic chips, particularly without any special facilities or the equipment. These new technologies lead the possibility of using point-of-care testing devices that can be manufactured quickly in the field by lowering the production cost. These paperbased technologies will contribute to solve many of the deadliest medical problems in developing countries and ultimately improve the quality of human life.

As COVID-19, which occurred at the end of 2019, has become a global pandemic, it has emerged as an unprecedented event that quickly destroys a nation's medical and healthcare system in both developed and developing countries. In the 21st century, most of the civil society that aimed for hyperconnected society is facing a new crisis that has not been experienced so far. Indeed, lack of personal protective equipment, isolation of clustered communities, disruption of medical systems necessary for diagnosis and treatment, and disruption of educational and economic activities due to social isolation are emerging. Since the COVID-19 has occurred, many of the difficulties that have occurred in the past six months indicate the basic infrastructure a society should have particularly in a pandemic. These include personal protective equipment (PPE), decontamination and quarantine tools essential for effective response, rapid and precise large-scale diagnosis, medical devices required for patient care, and identification and fast and wide on-line networks that can be used in social isolation. In this first part, we would like to introduce some representative examples of 1) personal protective equipment, 2) prevention of personal and community health, 3) social response through big data and networks within the framework of appropriate technology.

Recently, with the development of the 4th Industrial Revolution era and the popularization of technologies the maker movement is spreading worldwide in various ways for education, entrepreneurship, and solving social problems. This paper introduces a case of establishing and operating a maker space in Tanzania, East Africa, one of the developing countries. iTEC Tech-shop was established in the first half of 2018 at the Nelson Mandela African Institution of Science and Technology (NM-AIST) in Arusha, Tanzania by Innovative Technology and Energy Center (iTEC), and has been operating for nearly two years. With the allocation of empty warehouse space from NM-AIST, physical facilities were established through the purchase and installation of equipment and hand tools. Based on the advice from Idea Factory of Seoul National University and Fab-Lab Seoul, iTEC Tech-shop operational system were established. Through a total of 7 technical workshops, iTEC Tech-shop provided training courses for about 180 local personnel. In addition, the smart Techshop test-bed project was promoted in order to improve the operation level along with securing sustainability of the Techshop. The case of the iTEC Tech-shop could be a useful case for institutions or organizations promoting the maker movement to developing countries.

The purpose of this study is to develop and implement the Appropriate Technology Science School program (ATSS) for youth operated by the Europe-Korea Conference on Science & Technology (EKC) since 2016. The development process consisted of pre-online management meetings, online and offline tutor training, operation of ATSS for youth, and satisfaction surveys. As a result of the development, the management team selected the mission-solving theme of "Transforming village using blockchain technology" through a pre-online meeting. The contents were reorganized according to the level of the participating tutees, and various learning activities such as co-building activities, games, and plays were newly introduced and developed first, and the programs developed through tutor training were demonstrated and improved. A total of 38 tutees and tutors from 6 countries participated in the 2018 ATSS. As a result, participants showed positive satisfaction overall. Tutees showed interest in dome co-building activities and hash function calculation activities, and tutors showed interest in lectures and monopoly games related to blockchain technology. The development and of the 2018 ATSS will contribute to the improvement of expertise in the operation of the EKC ATSS in the future to the management team. It will be an opportunity for tutors to experience that high-tech science and technology have a good impact on appropriate technology for the third world and community society. In addition, Tutees will be provided with an opportunity to indirectly experience the local situation and community society through a role play on the impact of blockchain technology on African villages.

수변전설비는 전기설비 중에서 가장 중요한 것으로 보통 전력회사의 배전선으로부터 특고압으로수전하는 경우와 공장구내의 2차변전설비로서 설치된 경우가 있다. 수변전설비의 계획이나 증설, 재배치, 등에서는 적정한 위치선정, 수변전실의 넓이, 용량 등을 살려야 한다. 그리고 수변전설비의 변압기용량, 차단기용량 및 콘덴서용량 등에 대해서 용량의 적정화를 검토한다.
