In this paper, we introduce four different approaches of proving Cayley formula, which counts the number of trees(acyclic connected simple graphs). The first proof was done by Cayley using recursive formulas. On the other hands the core idea of the other three proofs is the bijective method-find an one to one correspondence between the set of trees and a suitable family of combinatorial objects. Each of the three bijection gives its own generalization of Cayley formula. In particular, the last proof, done by Seo and Shin, has an application to computer science(theoretical computation), which is a typical example that pure mathematics supply powerful tools to other research fields.

This study aimed at developing a family life education program to assist North Korean defector adolescents in their acculturation and adjustment process into South Korea. The program focused on building positive social relationships and managing healthy living, to allow them to develop appropriate skills needed to achieve social self-sufficiency. Researchers conducted interviews with defector adolescents as well as teachers of charter schools for defector students in order to identify the adolescents' needs. The contents of the program were carefully chosen to reflect the needs identified through the interviews. The program provides hands-on projects that are relevant to students' lives and consists of 10 study units that deal with different aspects of family life: food and dietary life, appearance and clothing, housing and community life, family and personal relationships, consumption, etc. The program was implemented in September through December, 2015, at Yeomyung School, which is an alternative highschool for North Korean defector adolescents. The program is expected to help North Korean defector students adopt the skills by experience and apply them in their daily life situations.

With the global rise in interest in competency-based education, the Ministry of Education of the Republic of Korea outlined six core competencies in the 2015 revised curriculum, essential for future society's 'creative and convergent talent'. This study introduces an HTE-STEAM constellation education program designed to develop the core competencies outlined in the 2015 revised curriculum and address the limitations of hands-on astronomy education. The program's effectiveness was assessed through a pilot test. The program was implemented at G Library, an out-of-school education site in Cheongju-si, Chungcheongbuk-do, targeting students from 3rd to 6th grade. The study's results include: First, the HTE-STEAM program significantly impacted all aspects of the STEAM attitude test except for 'self-concept', particularly influencing 'science and engineering career choice', 'consideration', and 'communication'. Thus, it has led to positive outcomes in the cultivation of future society's core competencies, including 'creative thinking skills', 'communication skills', and 'community skills'. Secondly, the HTE-STEAM constellation education program, despite covering the challenging concept of spacetime, was deemed easy by many students. Observations of students applying the spatial concepts they learned by using teaching aids suggest that the program was effective in enhancing students' understanding of the spatial structure of the sky and the universe. Additionally, this program aligns with the 2022 curriculum's updated standards for understanding the sky's spatial structure. Consequently, the HTE-STEAM constellation education program positively cultivates future society's core competencies and serves as a valuable complement to night observation practices in schools.

Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

Safety education delivered to construction workers in a lecture manner has limitations in concentration and immersion, so delivery power and interest are low. In order to improve unstable behavior through education and prevent safety accidents, it is necessary to change the paradigm to hands-on education. Purpose: Experiential safety education aims to contribute to preventing accidents for construction workers by quickly recognizing risks, improving emergency response skills, and verifying the effectiveness of pre- and post-learning. Method: Based on a survey of workers who experienced the same work environment as the actual construction site, an opinion survey on the pre- and post-safety experience education and a variable measurement tool were planned, and a research hypothesis was established. Results: The Bayesian theory and MC simulation analysis were used to analyze the structural equation model, and the change in construction worker behavior was confirmed through the intended safety (A), non-experiential education in the sub-area of anxiety (B), average, standard deviation, and minimum and maximum values. Conclusion: The effect of education and industrial accidents are reduced only when construction workers are motivated to participate.

Purpose: This study aimed to assess the effect of rowing ergometer training on the aerobic capacity and strength of male high school students over a 12-week period. Methods: Fourteen high school students volunteered to participate in the study. The subjects were divided into two groups: seven subjects in the experimental group and seven in the control group. The subjects in the experimental group performed rowing ergometer training for 75 min per session at three days a week for 12 weeks. The exercise intensity set the maximum heart rate (HRmax) from 40% to 80%. Aerobic capacity was measured by ventilation, cardiac output, and oxygen intake per body weight. Strength was measured by grip strength and back strength before and after training. Results: A significantly increased ventilation (p=0.01), cardiac output (p=0.01), and oxygen intake per body weight (p=0.00) were found in the experimental group. A significantly increased grip strength in the right and left hands (p=0.00, 0.00) and back strength (p=0.04) were observed in the experimental group. Conclusion: Rowing ergometer training can be an effective combined exercise for aerobic capacity and strength of high school students.

This study analyzes and compares the geomorphic characteristics and environmental changes of coastal plains such as the Anju and Hamheung Plains located in the west and east coasts of North Korea, respectively, based on topographic maps of the 1910s and satellite images of the 2000s. The Anju Plain, so called by as Yeoldusamcheonribeol, can be divided into alluvial plains, coastal plains and erosional plains. The Hamheung Plain can be regarded as alluvial plains formed by Seongcheon-river. Approximately 84.98$km^2$ tidal flats have been reclaimed to farmlands and saltpans, and the most channels of medium and small rivers have been straightened at the Anju Plain during the last one hundred years. At the Hamheung Plain, on the other hands, approximately 3.40$km^2$ land has been increased by the advances of coastal line of the Seongcheon-river delta with a maximum of 800m, and channels of Seoseongcheon-river which showed anastomosing channels have been disappeared by reclamation. Gwang-po has been decreased by artificial reclamations and river sedimentary processes.
