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.

This study aimed to confirm the status of media reports on space hazards using topic modeling analysis of media articles that are related to space hazards for the past 12 years. Therefore, Latent Dirichlet Allocation (LDA) analysis was performed by collecting over 1200 space hazards articles between 2010 and 2021 on solar storm, artificial space objects, and natural space objects from BIGKins news platform. The articles related to solar storm focused on three topics: the effect of solar explosion on satellites; effect of solar explosion on radio communication in Korea, centered on the Korean Space Weather Center; and relationship between aircrew and space radiation. The articles related to artificial space objects focused on three topics: the threat of space garbage to satellite and space stations and the transition of useful objects into space junk; the relationship between space garbage and humanity as shown in movies; and the effort of developed countries for tracking, monitoring, and disposing of space garbage. The articles related to natural space objects focused on two topics: International Space Agency's tracking and monitoring of near-Earth asteroids and the countermeasures of collisions, and the evolution and extinction of dinosaurs and mammals, with a focus on the collisions of asteroids or comets. Therefore, this study confirmed that domestic media play a role in conveying dangers of space hazards and arousing the attention of public using a total of eight themes in various fields such as society and culture, and derived education method and policy on space hazards.

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.

In this paper, we investigate the properties of the semi-continuous functions on the first axiom space, n-th product space, pseudo-metric space, and proximity space. Counterexample is used when the converse of the theorem is not hold.

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.

In this paper, we prove common fixed point theorems for semi-compatible mappings on intuitionistic fuzzy metric space with different some conditions of Park and Kim [10]. This research extended and generalized the results of Singh and Chauhan [14].
