Purpose of study: Recognizing the importance of securing professionalism in church education in the context of the serious problem of church eucation in the Korean church today, this study aims to reveal the problems of current church education and suggest alternatives for solving the problems. Research content and method: The Korean church is facing crises. One of the crises is the decline in church membership and worship attendance. Another, more fundamental problem is the crisis of church education, where the number of students in Sunday schools is plummeting, and many young people are leaving the church. Many of them are questioning the quality of church education leaders. The decline and demise of Sunday schools does not bode well for the future of the Korean church. What the church needs to do to address these issues is to build up educational professionals. Leadership and professionalism are critical issues. Until now, the needs of church education in the Korean church have relied on dedication and life mission rather than professionalism. And these criteria were enough. It has been 34 years since the October 1989 resolution of the General Assembly of the Christian Church in Korea to establish a system of educators. However, little progress has been made and the system has not been changed to a system of educators. One of the ways to solve this problem is for the Korean church to prepare for the future of the Korean church by utilizing educators for church growth and the restoration of Sunday schools. Conclusions and Suggestions: For the function, mission, and purpose of the church, the system of educators is requested to be established in the Korean church as soon as possible to fulfill the professional church education and educational pastoral mission. In response to this call, current Korean church education needs to change and innovate. The direction of innovation is professional education, which means that there is a need and urgency for professional educators qs church education leaders.

This study employs photovoice research methodology to investigate adolescents' experiences in sibling relationships and to analyze the impact of sibling interactions on their development and growth. The participants comprised eight high school students with one sibling (four males and four females) residing in the Incheon region. The research process encompassed several stages: participant recruitment, orientation, photovoice activity (focus group interviews), data analysis, and conclusion derivation. During the photovoice activity, participants engaged in a narrative process of photographing, interpreting, and discussing their experiences. The narratives were categorized into four primary themes: structure and environment, emotional interactions, roles, and parental subsystems. The conclusions drawn from the study are as follows: First, the similarity formed in sibling relationships during adolescence contributes to psychological stability. Second, roles and expectations based on birth order can cause stress for adolescents, indicating the need for equitable role adjustments within the family. Third, conflict in sibling relationships is crucial for enhancing problem-solving and social relationship skills. Lastly, consistent parenting attitudes significantly affect the emotional well-being of siblings. This study emphasizes the significance of fostering a deeper understanding of human development and family relationships through an exploration of adolescent sibling dynamics within home economics education.

The purpose of this study was to develop a program to prevent recurrence, focusing on cognitive and behavioral factors to reduce gambling game behavior in children, and to verify the effectiveness to analyze basic data necessary for prevention education. Eight children in the 4th to 6th grades of male students were selected, an experiment and control group were formed, and the effectiveness was verified only after 3 months after the experimental group was conducted once a week. First, irrational gambling beliefs, the level of gambling problems, automatic thinking for children, and the level of gambling problems were reduced through cognitive behavior therapy programs to reduce gambling game behavior in children. Changes in maladaptive thinking that directly affect gambling game behavior instilled awareness of gambling game behavior. Second, self-control and impulsiveness, the behavioral variables, did not show any significant difference, but decreased in the overall average. Changes in cognitive variables influenced behavioral variables. Third, it was found to continue even 3 months after the end of the program. Changes in cognitive and behavioral variables later reduced children's gambling game behavior and helped school life and peer relationships through adaptive thinking.

It is difficult for mathematics teachers to develop mathematical modeling tasks and implement mathematical modeling lessons for their students. These difficulties serve as a reason why mathematical modeling lessons are not implemented well in school mathematics. In this study, we aimed to examine how preservice mathematics teachers (PMTs) modify mathematical modeling tasks in mathematics textbooks as a way to develop mathematical modeling tasks and how they implement the mathematical modeling lesson. In particular, we focused on how the openness and reality reflected in the task and the mathematical modeling process change as PMTs modify the tasks. We collected data through PMTs' evaluation reports on analyzing textbook tasks, task modification, lesson plans and implementations, peer evaluation, and self-evaluation. Then, we analyzed these data according to the case analysis process. The findings revealed that when PMTs modified the textbook task, they focused on and improved the openness and the defining variables and the model stages of mathematical modeling process. However, when PMTs implemented lesson, the openness and the defining variables and the model stages of mathematical modeling process were restricted again. PMTs did not focus on other stages. Based on these results, the theoretical and practical implications of the study was discussed.

In this study, we developed a STEAM program based on digital astronomical and space resources and applied it to 167 randomly selected elementary school students to examine the effectiveness of the STEAM program in enhancing creative problem solving skills. The results of this study are as follows: first, the statistical analysis of pre-test and post-test scores for creative problem-solving skills related to the STEAM program showed significant results (p<.05). This suggests that the STEAM program contributed to improving creative problem-solving skills through the procedural process involved in generating ideas and convergent thinking during the digital problem-solving. Second, the paired sample t-test based on the pre-test and post-test of the STEAM attitude test also showed significant results (p<.05). Analyzing digital materials and presenting pixel art projects positively influenced STEAM attitudes in terms of interest, communication, and usefulness. This underscores the need for developing integrative education programs utilizing advanced technologies in the future. Third, in the class satisfaction test conducted after the application of the STEAM program, the satisfaction factor scored an average of 3.55, interest scored 3.35, and overall class difficulty scored 3.46. The main difference from traditional classes was the focus on 'acquisition of future career information.' However, given the slight decrease in interest during the digital transformation and interpretation process, it is recommended that future classes allocate sufficient time for experiential activities. To generalize the developed program, future studies should consider various school levels, implementation periods, and difficulty levels.

This study is to identify the awareness and performance of hand washing according to the presence of Medical care onboard of Seafarers and provide basic data of education on hand washing that can be practically applied. 118 Seafarers were the study subjects and we distributed to those who agreed to participate in the study to carry out survey using questionnaire. The results showed that the average number of hand washing per day was 1~4 times (70 students, 59.3%). In the difference in hand washing perception according to the medical care board, statistically significant differences were found in all items except 'it needs to be completely dried after hand washing'(p<0.05). The difference in hand washing performance according to in-flight medical care was found to be statistically significant in all items except 'hand washing after coughing' and 'hand washing after touching money', 'before eating food such as drinks while working' and 'hand washing before patient contact' (p<0.05). The correlation between awareness and performance of hand washing showed that if awareness of hand washing is high, its performance is increased, too. We try to provide basic data of education on hand washing that can improve awareness and performance on hand washing based on the results of this study.

It has been 7 months since medical students boycotted classes and resident doctors left hospitals in protest against the government's policy to increase the number of doctors. As education was suspended and services at university hospitals reduced, medical gaps in medical care have emerged. As a result, concerns are growing about a potential crisis in the healthcare system. The reason for the doctors' strong opposition to the policy lies in several issues that need improvement in the government's decision-making process. By reviewing these issues, we look forward to drawing lessons for making better policy decisions in the future. First, because the evidence supporting policy decisions has various characteristics and scopes, it is important to thoroughly discuss these grounds with stakeholders. Second, the discussion structure for reviewing evidence and making decisions should consist of members capable of fully negotiating diverse perspectives and should be operated through a fair and transparent process. If these steps are not properly implemented, conflicts surrounding the evidence could escalate, thereby lowering trust in the government. When stakeholders lose trust in the government, the social costs of implementing policies may rise, and policy efficiency may decline. Therefore, it is time to restructure the decision-making system in the direction of reducing potential conflicts that may arise during the future policy implementation process and increasing trust in the government.

Recently, the use of generative AI has become more active in university education, but jewelry design education and research using generative AI are still insufficient. Accordingly, we would like to discuss the possibilities and limitations of visualization of jewelry design ideation and expression using generative AI in the jewelry design development education and ideation stage, as well as the experience and application of generative AI by college students. To analyze the impact of generative AI on the learning experience, it was analyzed from the perspectives of 'usability', 'usefulness', 'reliability', and 'satisfaction'. As a result, generative AI confirmed positive results in terms of usability and usefulness to trainees, and confirmed the potential for effects using personalized education and collective intelligence. The combination of jewelry design education and generative AI is part of convergence education, and the significance of this study is to lay the foundation for effective use in jewelry design education by analyzing learners' experiences and perceptions of using generative AI. This kind of education reflects the trends of the times for nurturing future society's talents and will contribute to the promotion of learners' broad creative thinking.

Most of oceanic current maps in the secondary school science and earth science textbooks have been made on the base of extensive in-situ measurements conducted by Japanese oceanographers during 1930s. According to up-to-date scientific knowledge on the currents in the Yellow Sea and the East China Sea (YES), such maps have significant errors and are likely to cause misconceptions to students, thus new schematic map of ocean currents is needed. The currents in the YES change seasonally due to relatively shallow water depths, complex terrain, winds, and tides. These factors make it difficult to construct a unified ocean current map of the YES. Sixteen major items, such as the flow of the Kuroshio Current into the East China Sea and its northward path, the origin of the Tsushima Warm Current and its path into the Korea Strait, the path of Taiwan Warm Current, the Jeju Warm Current, the runoff pattern of the Yangtze River flow, the routes of the northward Yellow Sea Warm Current, the Chinese Coastal Current, and the West Korea Coastal Current off the west coast of the Korean Peninsula, were selected to produce the schematic current map. Review of previous scientific researches, in-depth discussions through academic conferences, expert discussions, and consultations for three years since 2014 enabled us to produce the final ocean current maps for the YES after many revisions. Considering the complexity of the ocean currents, we made seven ocean current maps: two representative current patterns in summer and winter, seasonal current maps for upper layer and lower layer in summer and winter, and one representative surface current map. It is expected that the representative maps of the YES, connected to the current maps of the East Sea and the Northwest Pacific Ocean, would be widely utilized for diverse purposes in the secondary-school textbooks as well as high-level educational purposes and even for scientific scholarly experts.

Purpose : The aim of this study is to find the prevalence of obesity, the serum lipid levels and the age at menarche in adolescent female athletes and to examine the effects of exercise in adolescent stage. Methods : With a questionnaire regarding their age at menarche, physical measurement, body fat, and blood samples of the serum lipid levels to evaluate the hyperlipidemia were obtained from adolescent female athletes(n=107) and general adolescent students(n=650) who didn't exercise at regular intervals, aged 12 to 18 years. Results : The mean weight in the athletes' group was $53.3{\pm}7.3kg$ which was similar with $54.3{\pm}8.0kg$ in the control group. The mean height in the athletes' group was $161.4{\pm}5.4cm$, which was taller than $158.9{\pm}5.3cm$ in the control group. The prevalence of obesity by obesity index, body fat, and BMI in the athletes' group were significantly lower than in control group. There was no significant difference in age at menarche between two groups($12.6{\pm}1.3$, $12.9{\pm}1.2$). The levels of cholesterol, LDL cholesterol, and HDL cholesterol in the athletes' group were higher than in the control group. The levels of triglyceride in the athletes' group was lower than in control group. Conclusion : These data suggest the importance of exercise in adolescents for the prevention of obesity since it may reduce body fat and increase the height. There was no negative effect of exercise on the age at menarche. We think that more controlled assessment of nutrition, diet habit, hormonal effect and height are warranted to find the correlation with hyperlipidemia and exercise at the adolescent stage.
