Purpose: The purpose of this study was to construct a structural model that explains the factors affecting aggression among elementary school students and to verify their suitability. Methods: The study period was from June to August 2018. The study subjects were fifth- and sixth-graders at an elementary school. In total, 291 surveys were collected, of which 259 were analyzed. Data were analyzed using SPSS version 24.0 and AMOS version 24.0. Results: The fit of the final model was acceptable ($x^2=160.08$ [p<.001], GFI=.921, AGFI=.869, CFI=.919, SRMR=.057, and RMSEA=.086). Thus, eight of the 10 hypotheses were shown to be statistically significant. Conclusion: The results of this study indicate that positive and open parenting behaviors and training children to engage in self-control are needed to reduce their aggression. In addition, considerable attention and education are required in the home, school, and society so that children can learn to properly recognize and express their emotions and establish suitable beliefs regarding aggressive behavior.

Objective: The aim of this study was to compare gait patterns of elementary school male students in higher grades according to their character styles. Method: 4 extroverted character male subjects (height: $141.35{\pm}7.75cm$, weight: $43.65{\pm}5.80kg$) and 4 introverted character male subjects (height: $145.38{\pm}8.94cm$, weight: $42.15{\pm}10.71kg$) participated in this study. Results: As for walk styles of elementary school male students in higher grades according to their character patterns, there was not significant differences in gait cycle, stride width, stride length and walking speed. According to examination of average ratio of maximum vertical ground reaction force according to their characters divided by weight, elementary school male students in higher grades with extroverted character showed 114.69% of weight and students with introverted character showed 122.82% of weight, which exhibited that students with introverted character had larger ratio as much as 8.13% than students with extroverted character. The statistical significance level was 0.000 showing significant difference. Conclusion: Our results indicated that male students in higher grades with introverted character press ground hard and walk with strong steps. On the other hand, male students with extroverted character walk with light steps.

Purpose: This study was conducted to analyze physical symptom-related and life-style factors affecting suicidal ideation of senior grade students in elementary school. Methods: Physical symptom-related and life-style factors were used to investigate suicidal ideation among 663 elementary school students. From February 11 to 15, 2018, data were collected using a structured questionnaire and analyzed using the $x^2$ test, Pearson correlation analysis, and logistic regression analysis in SPSS for Windows version 22.0. Results: The factors affecting suicidal ideation were gender, family structure, economic status, academic performance, exposure to school violence during the past year, physical symptoms, drinking experience, smoking experience, sleeping time, and ramen noodle consumption. The regression analysis showed that exposure to school violence during the past year (odds ratio [OR]: 102.99, 95% confidence interval [CI]: 51.19~207.19, p=.001), number of physical symptoms (OR: 1.25, 95% CI: 1.12~1.41, p=.001), drinking experience (OR: 3.17, 95% CI: 1.66~6.06, p=.001), and game and internet usage time (OR: 2.08, 95% CI: 1.08~4.01, p=.029) affected suicidal ideation. Conclusion: This study revealed that physical symptoms and life-style significantly influenced suicidal ideation. Therefore, interventions to reduce suicidal ideation in children must focus on improving children's physical symptoms and life-style.

Objective: The purpose of this study was to examine the relative influences of senior elementary school children's communication level with their fathers and peer competence on their happiness. Methods: The subjects of this study were 310 fifth and sixth grade students attending elementary school in Jeollanam-do. They responded to the level of communication with their fathers, peer competence, and happiness. For the data, t-test, Pearson's correlation analysis, and hierarchical regression analysis were performed. Results: First, there were some statistically significant differences according to gender differences in self-esteem and a sub-factor of happiness and the differences according to grades in open-type communication and problem-type communication. Second, it was found that children's happiness was highly correlated with communication with their fathers and peer competence. Third, the factors having the greatest relative influence on overall happiness were in the order of peer competence, open-type communication, problem-type communication, and gender. The variables influencing and the order of relative influence differed according to sub-factors of happiness. Conclusion/Implications: The present study revealed that peer competence has a significant impact on children's happiness. The results of this study suggest that research and development of convergent programs that can improve communication with fathers, peer competence, and children's happiness are necessary.

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.

In this paper, we characterize and analyze the technology elements and their hierarchy for the college graduating students performing capstone design projects in a game software major. When graduating students in a game software major must make a game for graduation, they need to know the pertinent technologies and their hierarchy. Technology analysis for game making would mean for students to recognize how the low level technologies taught in freshman and sophomore periods are linked to the high level technologies taught in junior and senior periods. Also, the analysis would help the professors design the game software major curriculum in detail based on the levels and the hierarchy of the individual technologies.
