Purpose: Several published policy statements have warned against the risks associated with trampoline use and recommended safety guidelines. However, few studies have focused on trampoline-related injuries in Korea. This study aimed to assess the incidence and characteristics of pediatric trampoline-related injuries presented to Ulsan University Hospital. Methods: We retrospectively reviewed the medical records of children aged <16 years with trampoline-related injuries who visited our Emergency Department between 2008 and 2017. Results: Over the 10-year period, 178 trampoline-related injuries were reported, which represented a significant increase (P=0.016). Most (87.6%) of the injuries occurred during the last 5 study years, and a rapid increase in injuries was observed in children aged <6 years. Lower extremity injuries (62.4%) were the most common, followed by injuries of the upper extremities, head and face, and trunk, including injuries to the neck and spine. Sixty-seven children (37.6%) had fractures, and proximal tibia fractures were the most common. Fractures were significantly more common in younger children (<6 years old) than in older children (P=0.026). Conclusion: In Korea, the mechanism of trampoline injury is similar to that of injuries incurred in indoor trampoline parks but is characterized by smaller spaces and multiple users. Trampoline use and the incidence of trampoline-related injuries in children aged <6 years are increasing rapidly. Prohibiting the use of trampolines for children aged <6 years, restricting simultaneous use by multiple children, and ensuring adult supervision should be strictly emphasized. Public awareness and policy guidelines are needed to reduce the incidence of trampoline-related injuries.

Propionic acidemia is an inherited organic acid metabolic disorder. During chronic recurrent metabolic crisis, multiple blood transfusions can cause secondary hemochromatosis. We report a patient with propionic acidemia who had iron overload that resulted in liver dysfunction, cardiomyopathy and diabetes. When multiple blood transfusions are unavoidable, use of chelating agents for iron can prevent complications such as diabetes and hemochromatosis.

The purpose of this study was to investigate the prevalence of social anxiety among late School-aged Children and identify factors influencing the tendency to social anxiety. A self-report survey was conducted with primary school children who were in the 6th grades. Two hundred and seventy eight children were included in the study. The instruments utilized in this study were SASCA-K (Korean Social Anxiety Scale for children and adolescents), SES(Self-esteem Scale), CAPS(Child and Adolescent Perfectionism Scale), DSRS-C(Depression Self-Rating Scale for Children), and IPPA-R(Inventory of Parent and Peer Attachment-Revised version). Data were analyzed using descriptive statistics, t-test, One-way ANOVA, Pearson correlation and multiple regression with SPSS WIN 23.0 program. Social anxiety for the schoolchildren was positively correlated with perfectionism and depression, whereas self-esteem and attachment security was negatively correlated with social anxiety. Stepwise multiple regression analysis showed that 38.0% of the variance for social anxiety was significantly accounted for by self-esteem, self-oriented perfectionism, depression, attachment security (Father-communication). The most significant factor influencing social anxiety was self-esteem. Findings suggest that expanding health education, counseling and school-based health education programs is necessary to prevent and intervention mental problems of late School-aged Children through integrated intervention by schools, families and communities.

This study examined the effects of academic self-concept (internal factor) and maternal parenting behaviors (external factor) on academic delay of gratification (ADOG). Additionally, models predicting ADOG were compared between Korean and Malaysian children. The participants of this study were 100 Korean third graders and their mothers, and 100 Malaysian third graders and their mothers. The children completed the modified versions of the Academic Delay of Gratification Scale for Children, and Academic Self-Concept Questionnaire. The mothers completed the Parenting Attitude Test. Pearson's correlation tests, independent t-tests, and multiple regression analyses were conducted to test the research hypotheses. The results showed that Korean children reported higher ADOG and academic self-concept scores than that of Malaysian children. Moreover, academic self-concept was found to have a significant positive effect on ADOG among both Korean and Malaysian children. There was no significant gender difference in ADOG for both Korean and Malaysian children. However, the effects of maternal parenting behaviors on ADOG were only detected among the Malaysian children, particularly on Achievement Press. That is, only for the Malaysian children, maternal pressure about academic achievement was found to have a significant positive effect on ADOG. In conclusion, only academic self-concept was found to be a significant predictor explaining the variance in ADOG among Korean children. On the other hand, academic self-concept and maternal parenting behaviors were shown as significant predictors explaining the variance in ADOG among Malaysian children.

Objective: This study investigates the main effects and interaction effects of mother's reactions to young children's negative emotions on the children's problem behaviors. Methods: A total of 346 mothers with toddlers completed questionnaires, the data were analyzed using Pearson's correlation coefficient and multiple regression. Results: First, mothers' supportive response to young children's negative emotions, including expressive encouragement, emotion-focused reactions, and problem-focused reactions, showed negative relations with the children's internal and external problem behaviors. Mothers' unsupportive response to children's negative emotions, including distress reactions, minimization reactions, and punitive reactions, showed positive relations with the children's internal and external problem behaviors. Second, an interactive effect was observed. For external problem behavior, mothers' lower distress reactions accompanied by higher emotion-focused reactions, lower punitive reactions accompanied by higher emotion-focused reactions, lower distress reactions accompanied by higher problem-focused reactions, and lower punitive reactions accompanied by higher problem-focused reactions all decreased children′s problem behavior. However, for internal problem behavior, only mothers' lower distress reactions accompanied by higher emotion-focused reaction decreased children′s problem behavior. Conclusion/Implication: The main interaction effect on mothers' reaction to young children's negative emotional expression shows that preventive intervention is needed to address problem behavior.

The purpose of this study was to explore the effects of children's self-regulation and teacher-child relationships on children's social behaviors. Participants were 239 4- to 5-year-old children(114 boys, 125 girls) and their 23 teachers. The teachers completed rating scales to measure children's social behaviors and teacher-child relationships. Children's self-regulation was assessed by a mother reported questionnaire. Data were analyzed using descriptive statistics, Pearson's correlations and stepwise multiple regression analysis. The major results of this study were as follows: First, Children's social behaviors were partially correlated with children's self-regulation and teacher-child relationships. Second, The most influential factor by children's social behaviors was teacher-child relationship. Specially, teacher-child intimacy was the most powerful factor predicting children's asocial behavior and prosocial behavior. While teacher-child conflict was the most powerful factor influencing children's aggressive behavior, hyperactive-distractible behavior and anxious-fearful behavior. Findings are discussed in terms of the importance of teacher-child relationships in the context of program development and guidance for maladjusted children.

This study was conducted to investigate the effects of participation in adult education on cognitive function, and the mediating effects of relationships with children among older adults. This study employed data from the 2011 Elderly Survey, and a total of 8,668 older adults over 65-years old were used for analysis. Multiple linear regression analyses were used to examine the mediating effect of relationship with children based on the approach proposed by Baron & Kenny (1986). The results showed that participation in adult education increased cognitive function of older adults. Adult education participation also increased satisfaction with relationship with children, and relationship with children was found to have a mediating effect. These findings suggest that there is a need to recognize the importance of the relationship between older adults and children when developing education programs for older adults.

This study examined the influence of mothers' reading and scaffolding behaviors on children's emotional experiences and memory recall during picture book reading. Sixty children, aged 6 and their mothers participated in this study. Each child-mother dyad was observed in a lab setting which was designed to evaluate child-mother interactions during a picture book reading. The data were analyzed using correlation and multiple regression techniques. Our results indicated that mothers' task-oriented reading behavior affected the children's lack of positive emotions, whereas mothers' fun-oriented reading behavior was associated with the children's positive emotions. The task-oriented reading behavior also accounted for children's poor memory performance in relation to the book. These results were discussed in terms of the relationship between emotion and cognition through book reading experiences.
