Aircrews and passengers are exposed to radiation from cosmic rays and secondary scattered rays generated by reactions with air or aircraft. For aircrews, radiation safety management is based on the exposure dose calculated using a space-weather environment simulation. However, the exposure dose varies depending on solar activity, altitude, flight path, etc., so measuring by route is more suggestive than the calculation. In this study, we developed an instrument to measure the cosmic radiation dose using a general-purpose Si sensor and a multichannel analyzer. The dose calculation applied the algorithm of CRaTER (Cosmic Ray Telescope for the Effects of Radiation), a space radiation measuring device of NASA. Energy and dose calibration was performed with Cs-137 662 keV gamma rays at a standard calibration facility, and good dose rate dependence was confirmed in the experimental range. Using the instrument, the dose was directly measured on the international line between Dubai and Incheon in May 2023, and it was similar to the result calculated by KREAM (Korean Radiation Exposure Assessment Model for Aviation Route Dose) within 12%. It was confirmed that the dose increased as the altitude and latitude increased, consistent with the calculation results by KREAM. Some limitations require more verification experiments. However, we confirmed it has sufficient utilization potential as a cost-effective measuring instrument for monitoring exposure dose inside or on personal aircraft.

This study aimed to analyze the personality of 141 pre-service early childhood teachers who will be in charge of the quality of education in the early childhood curriculum and to verify the differences in the career resilience according to the personality types. Career resilirnce, which measures the ability to cope with various problems and create ideas according to the work environment, was judged to be a very important factor for teacher-child interaction and successful operation of the early childhood curriculum. The results of the study showed that, among personality types, in the case of extraversion and conscientiousness, groups with average scores or higher scored higher in creativity, flexibility, challenging spirit, and future orientation than the groups below. In the case of the openness personality, higher scores in creativity, flexibility and challenging spirit, and in the case of the agreeable personality, the group showed significantly higher scores in flexibility and future orientation. In the case of the neurotic personality, on the contrary, the group with below average score received higher scores in flexibility, challenging spirit, and future orientation. The significance of this study is that it suggests the need for comprehensive programs such as various extracurricular programs, curricula, and counseling to help and promote the formation of more positive personalities of pre-service early childhood teachers.

This paper proposes an artificial intelligence convergence education program for teaching the main concept and principle of Support Vector Machines(SVM) at elementary schools. The developed program, based on Jeju's natural environment theme, explains the decision boundary and margin of SVM by vertical and parallel from 4th grade mathematics curriculum. As a result of applying the developed program to 3rd and 5th graders, most students intuitively inferred the location of the decision boundary. The overall performance accuracy and rate of reasonable inference of 5th graders were higher. However, in the self-evaluation of understanding, the average value was higher in the 3rd grade, contrary to the actual understanding. This was due to the fact that junior learners had a greater tendency to feel satisfaction and achievement. On the other hand, senior learners presented more meaningful post-class questions based on their motivation for further exploration. We would like to find effective ways for artificial intelligence convergence education for elementary school students.

The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.

This study compared 431 acoustic terminology of South Korean industrial standards and North Korean national standards based on IEC 60050-801:1994 international standards. In addition, this study attempted to integrate acoustic terminology between the two Koreas. There were 139 (32.3 %) AA types with exactly the same form of terminology, 35 (8.1 %) Aa types with different spellings due to differences in linguistic norms, and 257 (59.6 %) AB types with completely different forms. Morphologically, there were more than twice as many different types of terminology as the same type. In the integration of acoustic terminology with different forms, 178 (61 %) North Korean terminology and 76 (26 %) South Korean terminology were adopted. we would like to overcome the limitations of this study through the following suggestions. First, the government should support academic exchanges between the two Koreas and encourage the establishment of common standards for acoustic terminology. Second, efforts should be made to share acoustic terminology data between the two Koreas and publish an integrated acoustic terminology dictionary. Third, South and North Korea should jointly launch a terminology committee to make efforts to revise international standards together.

This paper analyzes the spatial representations constructed by reality, filming, and narrative in the works of Hong Kong film director Wong Kar-wai, and how these spaces influence Hong Kong's urban culture, perception, and interpersonal relationships. To analyze Wong Kar-wai's films, Charles Sanders Peirce's semiotics concepts and Paul Virilio's spatial concepts were applied. Through this, we examined how the meaning embedded in the spatial representations of Wong Kar-wai's films could become a crucial factor in their success. Wong Kar-wai focused on the values of human relationships formed by society in his subject expression, directly representing the human inner world and prompting audiences to think about it. In this paper, we categorized the spaces depicted in Wong Kar-wai's films as public, private, and connective spaces, and analyzed them as a means to show the living environment and emotions of Hong Kong's youth. Through this, we determined that the spatial representations in Wong Kar-wai's films effectively demonstrate the cultural interpretation function of Hong Kong's citizen consciousness at the junction of Eastern and Western cultures and social connections. In conclusion, Wong Kar-wai's works provide a rich understanding of contemporary people's lives, emotions, and urban spaces, offering valuable insights into Hong Kong's film industry and cultural values.
