This study examined the effect of interparental conflict and parent-child conflict on overt aggression in upper elementary school students and investigates if children's father-child conflict or mother-child conflict mediated the effect of interparental conflict on overt aggression. The participants of this study were 532 of fifth to sixth graders from three elementary schools located in Seoul and Gyeong-gi province. Participants were asked to respond to a written questionnaire to measure research variables of the Peer Conflict Scale, the Conflict Tactics Scales, and the Conflict Behavior Questionnaire. Data were analyzed by descriptive statistics and hierarchical multiple regression. Mediating effects were examined using analysis procedures of Baron and Kenny. The major findings were as follows: first, the level of interparental conflict and parent-child conflict of both mothers and fathers in upper elementary school students increased the level of overt aggression. Second, parent-child conflict of both mothers and fathers in upper elementary school students partially mediated the relation between interparental conflict and overt aggression. Higher levels of interparental conflict resulted in higher levels of parent-child conflict, and the subsequently higher frequency of overt aggression in upper elementary school students.

Since elementary school is a time in which basic concepts like attitudes and mindsets about careers are formed, career education is very important to elementary school students. This study was conducted to investigate the effects of a gardening program applying the academic disciplines of Science, Technology, Engineering, Arts, Mathematics, and Society (STEAMS) on developing career education for elementary school students. In order to determine the effectiveness of the program on career development of elementary school students, this study was conducted with 28 upper elementary students in the experimental group who participated in the gardening program, and 30 upper elementary students in the control group who did not. The program was comprised of total 8 sessions, one session per week, with various garden activities. The career development scores of the two groups before and after the program were comparatively analyzed. Before the program, the experimental group had significantly lower scores for career development than the control group. After 8 weeks of the program, the control group did not show any changes in career development, while the experimental group that participated in the program showed a significant increase in career development, resulting in no difference in career development between the two groups after the program. Therefore, the program has positive effects on improving career development of upper elementary students who previously had insufficient career development. Overall, the program had positive effects on career development of upper elementary students, and further research is needed to systematically promote the STEAMS-based gardening program to promote interest and understanding of students by associating plant-based gardening activities with various subjects such as science, art, and social studies.

This study examined the influence of bullying victimization on reactive aggression among upper elementary school students, and the mediating effect of victim justice sensitivity on the relationship between such victimization and aggression. It also investigated whether negative urgency moderates the influence of bullying victimization on reactive aggression. The participants were a group of 262 children (114 boys and 148 girls) who were fourth to sixth-grade students from 10 elementary schools located in Seoul, Gyeong-gi, and Daegu. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and SPSS Process Macro Model 5. The results were as follows: First, victim justice sensitivity mediated the influence of bullying victimization on reactive aggression among upper elementary school students. Second, negative urgency moderated the effect of bullying victimization on reactive aggression, whereas the impact of this was greater when the level of negative urgency was high. The results suggest that reactive aggression among upper elementary school students could be effectively decreased by preventing bullying victimization, and reducing the level of victim justice sensitivity and negative urgency.

This study examined the effects of perceived discrimination on multicultural adolescents regarding feelings of This study examined the direct effect of socially prescribed perfectionism on interpersonal anxiety in upper elementary school students and the sequential mediating effect of dichotomous thinking and rejection sensitivity on this relationship. The sample comprised 306 upper elementary school students (grades 4 to 6; 149 boys, 48.7%) in Seoul, Incheon, and Busan. The Data were collected through an online self-report questionnaire completed by the participants and analyzed using SPSS version 27.0 and MPlus version 8.7 software. The analyses revealed three key findings. First the direct effect of socially prescribed perfectionism on interpersonal anxiety was not statistically significant. Second dichotomous thinking mediated the relationship between socially prescribed perfectionism and interpersonal anxiety, whereas rejection sensitivity did not. Finally, socially prescribed perfectionism influenced interpersonal anxiety through the sequential mediation of dichotomous thinking and rejection sensitivity. In conclusion, although socially prescribed perfectionism does not directly influence interpersonal anxiety, children may experience interpersonal anxiety in situations involving dichotomous thinking due to socially prescribed perfectionism, leading to rejection sensitivity. These findings suggest that interventions for interpersonal anxiety in upper elementary school students should focus on psychological problems attributed to socially prescribed perfectionism.

Purpose: This study was designed to examine the factors related to school adjustment of upper graders in elementary school. Methods: Data was collected through a questionnaire survey of 304 fifth and sixth grade students from October to November, 2014. The collected data was analyzed statistically through frequency, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient and multiple regression analysis, using the SPSS/WIN 22.0 program. Results: First, subjective school record and subjective health status showed significant differences in school adjustment. Second, social support and ego-resilience were positively correlated, while bullying was negatively correlated with school adjustment. Third, significant factors related to school adjustment were social support, ego-resilience, subjective school record. These variables explained 56.4% of the students' school adjustment. Bullying was negatively correlated with school adjustment, but the correlation disappeared in the multiple regression analysis, where protective factors such as social support, ego-resilience were controlled for. Conclusion: School nurses should develop plans to enhance social support (teacher support, parents support, friends support) as well as programs to improve the ego-resilience of upper elementary students to help them adjust to school and to prevent and manage bullying. Also family, school and the community should be connected cooperatively with each other.

Objectives: The purpose of this study was to provide basic data for air pollutant exposure modelling and understanding the contribution of respective microenvironments by assessing the time-activity patterns of Korean students according to variables such as grade, sex, weekday, and weekend. Methods: In this study, we compared the residential time of 521 (both weekday and weekend) lower elementary students, 1,735 (1,054 on weekdays, 681 on weekends) upper elementary students, 2,210 (1,294 on weekdays, 916 on weekends) middle school students, and 2,366 (1,387 on weekdays, 979 on weekends) high school students in different microenvironments according to grade, sex, weekday, and weekend. We used data from the 2014 Time-Use Survey by the Korean National Statistical Office for upper elementary students through high school students, and surveyed time-activity patterns of 521 lower elementary students aged 7-9 years. Each microenvironment was divided into indoor, outdoor, and transport. Indoor environments were divided into home, school, and other places. In addition, the results of previous studies were compared to this study. Results: Weekday time-activity patterns of Korean students indicated that lower elementary students spent $16.02{\pm}2.53hr$ in the home and $5.37{\pm}2.32hr$ in school. Upper elementary students spent $14.11{\pm}1.79hr$ in the home and $6.27{\pm}1.37hr$ in school. Middle school students spent $12.83{\pm}2.22hr$ in the home and $7.48{\pm}1.88hr$ in school. High school students spent $10.65{\pm}2.86hr$ in the home and $10.23{\pm}2.86hr$ in school on weekdays. High school students spent the least amount of time in the home and the most time in school compared to other grades Conclusions: Students spent most of their time indoors, including in the home, school, and other indoors. On weekdays, as the grade increases, home residential times were decreased and school residential times were increased. Differences in time-activity patterns according to sex were not found for either weekdays or weekends. It is estimated that Korean students could be affected by school indoor air quality. High school students could be most affected by school indoor air quality since they spent the most time at school.

This study compared the food habits and attitudes towards dietary life culture in types of feeding management, gender and grade. The subjects were 352 elementary school students who lived in Seocheon, Chungnam. The independently managed school students were better than jointly managed school students in food habits (p<0.05). In skipping school meals, upper grade students were skipped more than lower grade students (p<0.05). In rate of eating school meals, boys were faster than girls (p<0.001). The independently managed school students and the jointly managed school students were different on distasteful food. Boys disliked vegetables and girls disliked cereals and beans (p<0.05). Upper grade students ate more well-balanced meals than lower grade students (p<0.05). As for the question 'what you will do if the distasteful foods are provided through school meals', they responded. the highest percent of students, 'I will try once or twice'. And the response 'I have them for health' was higher independently in managed school students than the jointly managed school students (p<0.05), girls than boy (p<0.05), and the lower grades than the upper grades (p<0.05). As for the question 'what you will do if the distasteful foods are provided, after the guide for school meals was performed', the response, 'I will make an effort to have it' accounted for the highest percents, and there were differences in lower grade students who were high percents than upper grade students (p<0.01). As for the recognition for unbalanced diets, most of the students recognized that it is a 'bad habit'; the girl students accounted for more percentage than boys (p<0.05). The criterion of food choice were different in gender and grade (p<0.01). As for the factor of influences for the food habits formation, lower grade students were 'school education' and upper grade students were 'parents' (p<0.05). Thus, the systematic guide for proper intakes of nutrition should be performed. Also, the time when students can be educated by an expert of nutritional education, which is connected with school meals and students can grow healthily.

Elementary science curriculum is designed to be closely-related magnetism with electricity in a physics domain and this paper explored whether elementary school students have recognized of relationships between them and whether there are any trends in the degree of recognition by grades. The elementary students of 3rd to 6th grade (total 154 persons) in a school in a local city participated in the experiment. Two forms of questionnaire were administrated to each grades. In the first questionnaire about magnetism, students were asked to rank the physics terms as the degree of proximity into magnetism and to write briefly the reason. In the second questionnaire about electricity, students were asked to do the same routine. The closer to the central term in the diagram, the lower score were given and the terms were classified as closely related to magnetism, electricity and the rest. Calculated the response frequency and averaged by the ranked terms, it was examined that the scores of proximity in how students closely rated conception to magnetism and electricity. The result said that the upper grades students showed the degree of proximity with magnetism and electricity as closely. Therefore, the sequence of comprehension of magnetism and electricity concept, which was found in the elementary school curriculum, seems to be found in the elementary students＇ recognitions by grades.
