The Korean Astronomical Society (KAS) Education & Public Outreach Committee has provided education services for children and school teachers in Cambodia over the past three years from 2016 to 2018. In the first year, 2016, one KAS member visited Pusat to teach astronomy to about 50 children, and in the following two years of 2017 and 2018, three and six KAS members, respectively, executed education workshops for ~ 20 (per each year) local school teachers in Sisophon. It turned out that it is desirable to include both teaching of astronomical knowledge and making experiments and observations in the education in order for the program to be more effective. Language barrier was the main obstacle in conveying concepts and knowledge, and having a good interpreter was very important. It happens that some languages, such as the Khmer of Cambodia, do not have astronomical terminologies, so that lecturers and even the education participants together are needed to communicate and create appropriate words. Handout hard-copies of the education materials (presentation files, lecture/experiment summaries, terminologies, etc.) are extremely helpful for the participants. Actual performing of assembling and using astronomical telescopes for night sky observations has been lifetime experience for some of the participants, which might promote zeal for knowledge and education. It is hoped that these education services for developing countries like Cambodia can be regularly continued in the future, and further extended to other countries such as Laos and Myanmar.

In this study, a learning environment based on STEAM theory was proposed to support and improve learners' activities and achievements for convergent design education. The learning environment design influence STEAM education with intentional design and schedule coordination, schools can create informal environments that are crucial to STEAM education. The physical surroundings of the learning space should be applied to teaching methods and learning activity, especially for STEAM-based education, physical space conditions should support the learner's design thinking and process. Furthermore, STEAM-based education environment should support a vast array of experiences that allow students to learn the context around ideas and skills. For spaces for learning environment based on STEAM, common design principles should be considered such as technology integration, safety and security, transparency, multipurpose space, and outdoor learning. Therefore, the learning environment based on STEAM needs flexible and mobile, connected, integrated, organized, flipped, and team-focused surroundings to support the learners understand, participate, cooperate, and accomplish the design process.

본 연구는 지난 12년간의 우주위험 관련 언론기사의 토픽모델링 분석을 통해 우주위험별 언론 보도 현황을 알아보기 위한 목적으로 수행되었다. 빅카인즈(BIGKinds)의 뉴스 플랫폼에서 2010년부터 2021년까지의 태양폭풍, 인공우주물체, 자연우주물체에 대한 우주위험 기사를 각각 1200여건 이상 수집하였으며, 키워드 분석, 잠재적 디리클레 할당모형(LDA) 분석을 수행하였다. 그 결과 태양폭풍 관련 기사는 3개의 토픽인 태양폭발이 인공위성에 미치는 영향, 우주전파센터를 중심으로 태양폭발이 우리나라 전파 통신에 미치는 영향, 항공종사자와 우주방사선의 관계로 요약되었다. 인공우주물체 관련 기사의 경우 3개의 토픽으로 인공위성과 우주정거장이 우주쓰레기로부터 위협을 받거나 그 자체가 우주쓰레기가 될 수 있다는 토픽, 영화를 통한 우주쓰레기와 인류의 관계에 대한 토픽, 우주쓰레기 추적·감시 및 처리를 위한 우주강국들의 노력이라는 토픽으로 요약되었다. 자연우주물체 관련 기사는 2개의 토픽으로 국제 우주기관의 근지구소행성에 대한 추적·감시와 충돌 대책과 소행성과 혜성 충돌을 중심으로 공룡과 포유류의 진화 및 멸종 원인으로 요약되었다. 이로부터 2010년부터 현재까지 국내 언론은 우주위험을 사회, 문화 등 다양한 영역에서 총 8개의 주제로 대중들에게 그 위험성과 경각심을 전하는 역할을 하고 있음을 확인하였으며, 이러한 결과를 기반으로 우주위험에 대한 교육방법과 교육정책의 필요성을 제언하였다.

Previously, Park et al. (2005) defined an intuitionistic fuzzy metric space and studied several fixed-point theories in this space. This paper provides definitions and describe the properties of type(${\beta}$) compatible mappings, and prove some common fixed points for four self-mappings that are compatible with type(${\beta}$) in an intuitionistic fuzzy metric space. This paper also presents an example of a common fixed point that satisfies the conditions of Theorem 4.1 in an intuitionistic fuzzy metric space.

이 논문에서는 Norman Levin의 논문에서 나타난 semi-open의 개념을 사용하여 정의된 semi-continuous의 여러가지 성질을 조사하였고, semi-continuity를 위상공간의 first-axiom공간 pseudo-metric공간과 n-th product공간까지 조사하였으며, semi-continuous함수의 합성과 함수열의 극한과 Proximity공간의 mapping에 대하여 조사하였다. 그리고 정리의 역이 성립하지 않는 경우 반례를 들어 보였다.

Today, the paradigm of education is changing from teacher-centered, facility-centered, supplier-centered to student-centered, people-centered, and user-centered. In 2019, the Ministry of Education promoted the school space innovation project to provide a school space as a balanced life space, such as learning, play, and rest, through educational activities led by students, who are the leaders of the future society. Based on this, Incheon Metropolitan City Office of Education prepared a manual for practice while carrying out a project to build a future classroom. In those projects 'user participatory design' is applied as a new design approach and facilitators play an important role as experts in the process of user participatory design. However, it is different from the guidelines by the Ministry of Education in terms of facilitator role; facilitator in Incheon's future classroom projects can be in charge of designer part. This was possible because the design scope was limited to the classroom space and the construction permit work was not applied, and the Incheon Metropolitan City Office of Education seems to be able to successfully implement the plan derived through 'user participatory design' under the responsibility of the facilitator. However, this may be considered to be inconsistent with the basic purpose of the school space innovation project. In the case of the school unit project, it is considered that more systematic supplementation is necessary.

It is true that the social welfare center influences on the community service. The recent change of social environment has influence on the configuration of space for the community social welfare center. The social welfare center fills the role of family welfare, domiciliary care, community welfare, education culture etc. Education culture magnified, and it is acting role as the community education culture center by various program including cultural desire according to the modern request to the whole local resident. In such sense, this study explore the conditions of spatial configuration for the education culture unit of social welfare center in small city. For this study, it was investigated the space role and service funtion, the service program, the usage characteristics, the service importance. In sum, the useful data were collected, analyzed, and colligated by case study. Case study and analysis contents about education culture unit of social welfare center present the basic design data for the space plan of suitable social welfare center in small city.
