This study aims to theoretically examine the educational and living elements that are needed for social education in the school system and suggest an approach to apply this result to the environmental aspects of the space in schools. To do this, characteristics of space in exemplary middle school oversee were analyzed. Also, the characteristics and status of the school space environment that foster socialization were examined. In order to increase students' social skills, the following community space should be considered. 1) teaching and learning spaces facilitating a variety of teaching methods, such as lecture, discussion, seminar classes, 2) open-spaces for communication among students, such as home base, hall, library, museum, and restaurant, 3) open-spaces for STEM education, 4) transparent windows located in the boundary wall between classrooms and hallways, 5) a large performance stage for presentation of student activities and experiences, 6) smart-learning spaces for fluent ICT system in classes and in public spaces, 7) restaurants and libraries located in the middle space of the school, and 8) ecological environments for student learning.

The atmosphere strongly affects the Earth's spin rotation in wide range of timescale from daily to annual. Its dominant role in the seasonal perturbations of both the pole position and spinning rate of the Earth is once again confirmed by a comparison of two recent data sets; i) the Earth orientation parameter and ii) the global atmospheric state. The atmospheric semi-diurnal tide has been known to be a source of the Earth's spin acceleration, and its magnitude is re-estimated by using an enhanced formulation and an up-dated empirical atmospheric S2 tide model. During the last twenty years, an unusual eastward drift of the Earth's pole has been observed. The change in the Earth's inertia tensor due to glacier mass redistribution is directly assessed, and the recent eastward movement of the pole is ascribed to this change. Furthermore, the associated changes in the length of day and UT1 are estimated.

The senior welfare centers should provide integrated welfare services to the elderly whose needs are in change. So this paper tried to find a direction for improvement by identifying the spatial organization of the centers which are in Yeosu, Suncheon and Gwangyang. Classification of spaces of senior welfare center followed the guidelines 2020 for senior welfare center from Ministry of Health and Welfare which are consultation, medical rehabilitation, day or short-term protection, social education, home welfare, employment, welfare and public relations and PR planning and by adding management and public space. The above factors are invested and analyzed. The results of the survey and analysis of seven senior welfare centers are as follows. First, in the survey, the spatial organization of the senior welfare centers surveyed showed that the larger the size is, the dominantly lager the social education space is. Second, the space for day or short-term care, and employment is less than 1% of the total area, and most senior welfare centers do not have a basic space for this. Third, the space related to home welfare and counseling is very small, and more than half of the senior welfare centers do not have space related to it.

There is no doubt that science -and, therefore, science education- is central to the lives of all (NGSS, 2013). This manuscript focuses on ideas in astronomy that are at the foundation of elementary students' understanding of the discipline: the apparent motion of the sun explaining the day / night cycle on Earth. According to prior research demonstrating that neither children nor adults hold a scientific understanding of the big ideas of astronomy (NRC, 1996), understanding of concepts may base students' progress towards more advanced understanding in the domain of astronomy. We have analyzed the logic of the domain and synthesized prior research assessing children's spatial representation from an earth- and a space based perspective to develop a set of learning trajectories that describe how students' initial ideas about apparent celestial motion as they take school science can be build upon. In this study elementary students' representations were compared by their resident context including urban and rural. This study may present a first look at the use of a learning progression framework in analyzing the structure of astronomy education. We discuss how this work may eventually lead towards the development and empirical testing of how children learn to describe and explain apparent patterns of celestial motion.

The purpose of this study was to investigate children's ideas about growth of plants and their conceptural change after instruction to apply SPACE (Science Processes And Concepts Exploration) Learning strategy. For this study, a total of 55 students from infants to 5th grade were sampled. Data were obtained by the individual interview procedure and summarized by using network analysis. The major results of this study were as follows : 1. A very small number of students responded reforming or reorganisation of materials about the mechanism of germination and growth inside the seeds. 2. Almost all students confused between conditions necessary for germination and growth. Water and sunlight were mentioned by many students, while air and temperature were mentioned by a few students as the condition. 3. Some of the students showed that growth occurs continuously. Many students explaned occurence of growth about Plants related to the night, monning, or evening. 4. With the explaning about the necessary conditions for caterpillar growth, students mentioned conditions related in terms of human experience. 5. Many young childrens showed tendency of the egocentric and human-centered view of the world. Students scientific concepts increased significantly with age. Many students conceptions depend on the context-specificity ideas.

제7차 수학과 교육과정의 도형 영역에서는 도형 움직이기나 쌓기나무와 같이 학생들의 공간 감각 형성을 위한 학습 내용이 새롭게 도입되었다. 그러나 실제 교수학습이 이루어지는 학교 현장의 교사들은 교수 활동의 어려움을 이야기하고 있으며 학생들의 학습 성취도 또한 낮은 편이다. 도형 학습을 비롯한 초등학교에서의 수학 교육은 실물의 조작을 통하여 이루어졌을 때 가장 효과적이겠으나 학교 현장에서는 여러 가지 여건상 실물을 통한 학습은 어려운 실정이다. 그러므로 이를 극복하기 위해 적절한 웹 자료를 활용한 학습이 이루어지도록 해야 하겠으나 공간개념 형성 학습은 본 교육과정에서 새롭게 도입된 학습 내용이기 때문에 웹 기반 학습 자료도 부족한 실정이다. 이에 본 논문에서는 공간감각 증진을 위한 학습 내용을 추출하여 학습자 스스로 웹을 통해 학습할 수 있도록 하고 학습자들 사이에, 또는 학습자와 교사 사이에 활발한 상호작용이 이루어질 수 있는 도형학습 시스템을 설계하여 구현하였다. 애니메이션을 통하여 원리를 이해하도록 하고 흥미를 갖고 참여할 수 있도록 게임을 통한 학습이 이루어지도록 개발하였다.

In this paper, we prove two optimal inequalities involving the intrinsic scalar curvature and extrinsic Casorati curvature of submanifolds of generalized space forms endowed with a semi-symmetric metric connection. Moreover, we also characterize those submanifolds for which the equality cases hold.

Application of space technology in the field of communication and remote sensing becomes increasingly important in human life. Advancement of communications means shinks the size of our globe and that of remote sensing techniques improves the quality of human well-being. It is a world trent for each country to make its best effort in advancing its capabilities in these fields sometimes independently and other times jointly with other nations. Korea being no exception to this world trend is planning various starategies in application and development of space technologies. However, unfortunately, Korea is a new commer in this field. Statellite Technology Research Center (SaTReC) of Korea Advanced Institute of Science and Technology (KAIST) initiated to aquire satellite technology by sending its graduates abroad in 1989. As a result KITSAT-1 was launched in 1992 and KITSAT- 2 was launched in 1993 and they became Korea's first two satellites in orbits. Academic program including On-the Job-Training for Korean students at the University of Surrey, UK, is also an innovative scheme of mixing education and practical know-how for successful technology transfer, which resulted in a small but very capable and effective satellite experts group in Korea for self-propelled research and development in space activities. In this context, space development strategy should be considered in terms of the following factors; (1). Participation in international space activities as an active member to utilize international organization and to contribute to the peaceful use of space, (2). Development of national defence structure for independent activities in space, (3). Enhancement of manpower utilization for space development and promotion of national pride and (4). Education of youngsters for the extension of intellectual activities into the limitless space. In order to make very costly space development project most efficient, governmental level space development organization directed by the head of nation should be established and should manage all space development programs making full use of its all available resources including the advantage of the university based R&D capability.
