The purpose of this study was to explore the factors predicting increased usage hours of smartphone among adolescents. Secondary data was analyzed to be collected from a nationally representative sample of 2017 Korean adolescents. This study sample included 54,601 students in middle or high schools of Korea. The collected data were analyzed SPSS version 23.0 program for frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficient and binary logistic regression analysis. In the results, the mean usage hour of smartphone among the adolescents was 28.42 (SD 23.30) per week. Analyses of the differences in usage hours of smartphone according to research variables were found that the groups of lower level of study (F=1361.067, p<.001) and sociality content type (F=761.549, p<.001) spent more time, as compared to the other groups. The logistic analysis showed the predictive factors for increased hour of using smartphone were smartphone usage for sociality (OR: 2.44, 95% CI: 2.26-2.64) and peer group counselor (OR: 1.49, 95% CI: 1.49). Conclusionally, the findings of this study suggests that it needs to understand cause or purpose of smartphone using of adolescent and to cope and educate on the cause.

This study explored the concept of artificial intelligence and the problem-solving process that can be explained through literature research. Through this study, the educational meaning and application plan of artificial intelligence that can be explained were presented. XAI education is a human-centered artificial intelligence education that deals with human-related artificial intelligence problems, and students can cultivate problem-solving skills. In addition, through algorithmic education, it is possible to understand the principles of artificial intelligence, explain artificial intelligence models related to real-life problem situations, and expand to the field of application of artificial intelligence. In order for such XAI education to be applied in elementary schools, examples related to real world must be used, and it is recommended to utilize those that the algorithm itself has interpretability. In addition, various teaching and learning methods and tools should be used for understanding to move toward explanation. Ahead of the introduction of artificial intelligence in the revised curriculum in 2022, we hope that this study will be meaningfully used as the basis for actual classes.

Recently, domestic schools are increasingly interested in environmental education related to COVID-19 and the severe climate crisis, as well as artificial intelligence education related to the 4th industrial revolution that is rapidly approaching us. In particular, AI education is highly likely to be applied to 5th to 6th graders of elementary school, so measures related to connection with 1st to 4th graders are needed. There are many students who are not proficient in computers in the lower grades of elementary school, so there may be many restrictions in using the currently used teaching aids. Therefore, this study tried to develop an artificial intelligence education program for the lower grades of elementary school to secure the linkage of artificial intelligence education. The theme of the program was developed based on the topic of environmental education, which has recently increased in interest. As for the educational method, considering the developmental stage of the lower grades of elementary school, the STEAM education method was used, which was fused with various subjects and unplugged using play and games without a computer. of the program. For validity verification, Lawshe (1975)'s content validity ratio (CVR) calculation formula was used. The verification results were analyzed to be suitable for the purpose of development of all programs. In the future, it is necessary to measure the degree of effectiveness by applying the program proposed in this study to the lower grades of elementary school.

The purpose of this study is to examine personal characteristics of two elementary students who developed individual interest in science. 201 students of two elementary schools in Seoul participated in questionnaire survey engaged in to investigate students' interest in science, engagements and preference in science-related-activities three times a year. This case study was conducted with seven students who showed typical types of interest in science. Students wrote a photo-journal for 12 weeks. They were interviewed every other week by a researcher. We analyzed two students who developed individual interest. It turns out that RF participated in doing experiments at home, and disassembling and assembling things. Participation of activities was a process of solving curiosity. When he was unable to solve problems, he searches the internet or books. Sometimes he would ask for help from his teacher. JW engaged in activities: drawing, doing experiments at home, and going to informal education center. She communicated with others by using online-offline media. Curious questions were solved by herself. The two students have a tendency to solve problems by themselves. Also, positive science-related activities were going on at home and in school. This study not only give insights and understanding of students who developed individual interest in science but also provide implication for educators to examine personal characteristics of students.

Rapid changes in modern society after the COVID-19 have highlighted artificial intelligence talent as a major influencing factor in determining national competitiveness. Accordingly, the Ministry of Education planned a large-scale SW·AI camp education project to develop the digital capabilities of 4th to 6th grade elementary school students and middle and high school students who are in a vacuum in artificial intelligence education. Therefore, this study aims to develop a camp-type SW·AI education program for students in grades 4-6 of elementary school so that students in grades 4-6 of elementary school can acquire basic knowledge in artificial intelligence. For this, the meaning of SW·AI education in elementary school is defined and SW·AI contents to be dealt with in elementary school are: understanding of SW AI, 'principle and application of SW AI', and 'social impact of SW AI' was set. In addition, an attempt was made to link the set elements of elementary school SW AI education and learning with related subjects and units of textbooks currently used in elementary schools. As for the program used for education, entry, a software coding learning tool based on block coding, is designed to strengthen software programming basic competency, and all programs are designed to be operated centered on experience and experience-oriented participants in consideration of the developmental characteristics of elementary school students. In order for SW·AI education to be organized and operated as a member of the regular curriculum, it is suggested that research based on the analysis of regular curriculum contents and in-depth analysis of SW·AI education contents is necessary.

The purpose of this research is to establish the foundation for understanding the appearance of development, inheritance and acceptance of Toegye Yi Hwang(退溪李滉, 1501~1570)'s theory after his life by examining Udam Jeong Sihan(愚潭 丁時翰, 1625~1707)'s view on the Ido-seol(理到說), the Toegye's latter theory. After Toegye, Ido-seol was translated as 'The principle of matters reaches the human mind'. Galam Yi Hyunil(葛庵 李玄逸, 1627~1704), the contemporary scholar with Udam, criticized this translation for applying the directivity and motility to 'Li', the immovable principle. However, Udam agreed with the conventional interpretation of Ido-seol and understood it as the consilience of mind which got the entire principle(體) of 'Li(理)' and contained the application(用) of all things. He extended this concept as the level of 'sameness between objects and self [物我爲一]' based on his former theory, the exquisite interpretation of 'application of Li'. The meaning of 'sameness between objects and self[物我爲一]' is not amalgamation but applepie order of matter's principle in mind. The Udam's viewpoint is differ from Galam who tried to overcome the structural limit of Ido-seol by transforming 'Do(到)', the predicate of 'Ido(理到)', into 'Jin(盡)'. It means that he tried to interpret 'Ido(理到)' on the more essential aspect. His view can be the useful tool for understanding the Toegye's neo-Confucianism system with 'Li(理)' as central figure. It suggested that Udam's theory of the principle and the applecation of 'Li' can be the important theory to investigate the formation of Toegye schools' though and its development.

This study aimed to explore the constructs of the characteristics of at-risk learners with diverse educational needs in the blind spots of education, in order to understand them comprehensively and detect them early in schools. Participants were 156 elementary, middle, and high school teachers who filled out a semi-structured questionnaire consisting of open questions about their implicit knowledge of the characteristics of at-risk learners in the blind spots of education. Qualitative data were analyzed using a modified consensual qualitative research method. The main findings of this study are as follows. First, five domains and 16 categories were derived as the main constructs of the characteristics of learners in the blind spots of education. Second, the most listed of the five domains was the "domain of low learning and cognition," whereas the least listed domain was the "everyday life domain." Finally, deficiencies of interpersonal skills and interactive communications and categories related to family structure and functions frequently appeared among the 16 categories. Based on these results, implications and potentials for follow-up studies were further discussed.

Objectives: The number of schools offering school lunches has increased in China. This study examined the dietary quality of the lunches consumed by Chinese school-age children and adolescents, with a focus on comparing school lunches with home lunches. Methods: The first weekday 24-hour dietary recall data of 6~17-year-old students (n=1,084) from the 2011 China Health and Nutrition Survey were analyzed. The subjects were divided into the school lunch group and the home lunch group, and the dietary quality of lunches was compared between the two groups among 6~11-year-old students (n=634; 177 in the school lunch group and 457 in the home lunch group) and 12~17-year-old students (n=450; 144 in the school lunch group and 306 in the home lunch group), respectively. Frequently consumed foods, amount of food group intake, food group intake pattern, Dietary Diversity Score (DDS), and Dietary Variety Score (DVS) were examined. Results: The most frequently consumed foods in both lunch groups were rice and pork. An excessive intake of meat and insufficient intake of seafood were noted in both lunch groups. The school lunch group showed a lower level of vegetable consumption than the home lunch group (P=0.017 in 6~11-year-old students, P=0.003 in 12~17-year-old students). Although more students ate meals with a better dietary pattern in the school lunch group than the home lunch group, there were no significant differences in DDS and DVS between the two groups. Conclusions: Overall, the dietary quality of lunches was not superior in the school lunch group compared to the home lunch group. This suggests that much room remain for improving dietary quality of school lunches in China.

This study is a descriptive research study to find out the relationship between degree of Self-Esteem, Anger-Out, Anger-In, Anger-Control and SNS Addiction Tendency of high school students, and the factors that influence SNS addiction tendency. For a total of 10 days from May 18 to 28, 2020, a total of 100 people were collected using online questionnaires to those who were attending high schools in S and G regions and using SNS. As a result of the study, SNS addiction tendency and self-esteem(r=.385, p<.001), anger-control(r=-.354, p<.001) showed a normal inverse correlation, and an anger-out (r=.321, p=.001), anger-in (r=308, p=.002) showed a common net correlation. Factors affecting SNS addiction tendencies were self-esteem(β=-.297, p=.001), gender(β=.266, p=.003), and anger-out(β=.247, p=.007), with 27.7% explanatory power in the regression model(F=12.279, p<.001). Therefore, it is necessary to develop programs to increase high school students' self-esteem and lower their anger-out in order to reduce SNS addiction tendencies, especially for female high school students in gender.
