This paper suggests the necessity of design education to engineering majors through qualitative research on the characteristics of intelligent artifacts. Robot cleaner is one of intelligent artificial objects that can approach people's life without awkwardness. How do people think of robot cleaners and define their personality, these days? In this experiment, subjects use and observe four different robot cleaners that have different appearances, behaviors and sounds in an experimental setup where is similar to actual use environment. We measure subjects' preferences and assessments for four different robot cleaners' personality. The test subjects were 11 designers who frequently collaborated with engineers and were able to express and express opinions about products. Experimental results showed that robot cleaners with the highest scores in appearance, behavior, and sound had the highest preference. In contrast, robot cleaners with low scores in three factors showed different results in the preference ranking.

There has been increasing necessity of more precise prediction and measurements of aviation radiation in Korea. For our air crew and passengers' radiation safety, we develop our own radiation prediction model of KREAM. In this paper, we validate the KREAM model based on comparison with Liulin observations. During early three months of this year, we perform total 25 experiments to measure aviation radiation exposure using Liulin-6K in commercial flights. We found that KREAM's result is very well consistent with Liulin observation in general. NAIRAS shows mostly higher results than Liulin observation, while CARI-6M shows generally lower results than the observations. The percent error of KREAM compared with Liulin observation is 10.95%. In contrast, the error for NAIRAS is 43.38% and 22.03% for CARI-6M. We found that the increase of the altitude might cause sudden increase in radiation exposure, especially for the polar route. As more comprehensive and complete analysis is required to validate KREAM's reliability to use for the public service, we plan to expand these radiation measurements with Liulin and Tissue Equivalent Proportional Counter (TEPC) in the near future.

Life safety awareness level diagnosis is necessary for customized safety education and continuous safety awareness. As the starting stage of safety education for each life cycle, a scale that has verified the reliability and validity of high school students' life safety awareness has not yet been developed. In this context, the purpose of this study is to develop and validate the life safety awareness scale of high school students and to analyze interindividual differences. Questionnaire data was collected from April to June 2022 from 834 students in the first, second, and third grades of high schools in △△ city in Jeollabuk-do. A final 25-item scale was developed using the preliminary survey, preliminary test, the main test, descriptive statistical analysis, and exploratory and confirmatory factor analysis. This scale consists of four sub-factors: 'safety prevention', 'safety knowledge', 'safety preparation', and 'safety protection'. Good reliability and validity were verified by analysis of content validity and construct validity. The generalizability of the scale was verified by crossover validation between the search group and the crossover group. Based on the interindividual differences analysis, although there was a difference between genders in life safety awareness, there was no difference by grade level and academic achievement. This study is significant in developing the first valid scale that can measure high school students' life safety awareness and providing the necessity and rationale for life safety education by life cycle considering individual gender differences.

Objective: This study aimed to examine childcare teachers' perceptions and practice of music-math integrated activities, and their understanding of these activities. Methods: This study involved 201 childcare teachers from Seoul and surrounding areas. Surveys were employed to collect data on their background, implementation of music-math integrated activities, and the challenges they encountered. Additionally, a tool was also developed and utilized to measure the actual understanding of these activities. Data were analyzed using t-tests and ANOVA. Results: The results indicated that while teachers recognize the importance of integrated activities, they seldom implement them due to challenges related to resources and comprehension of concepts. Significant differences in the understanding of these activities were found based on teachers' experience, workplace type, age group of children under their care, and education level. Conclusion/Implications: In conclusion, the findings emphasize the necessity for the development and provision of pre-service and in-service training programs, along with support in educational materials for childcare teachers. These efforts are crucial to facilitate the effective implementation of music-math integrated activities.
