Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

Objective: The purpose of this study was to examine the sequential mediating effects of self-esteem and positive peer play interaction between warmth parenting and the social competence of preschoolers. Methods: The 7th wave of the Panel Study on Korean Children(2014) was used to analyze 1,113 preschoolers. Sequential mediation effects were analyzed using SPSS Process Macro(Hayes, 2013). Results: Warmth parenting indirectly affected preschooler's social competence (cooperation, assertion, self-control) by yielding sequential mediation effects on self-esteem and peer play interaction. Namely, warmth parenting does not directly affect social competence but does have a significant effect on preschooler self-esteem, which positively affected peer play interaction. This path increases the social competence(cooperation, assertion, self-control) of preschool children. Conclusion/Implications: In order to increase the social competence (cooperation, assertion, self-control) of preschool children, it is important for the preschooler to consider themselves a worthy person and to learn positive interaction techniques through warmth parenting.

Objective: The study aimed to examine the impact of a supportive school environment on children's prosocial behavior by investigating the sequential mediating effects of children's self-esteem and happiness. Methods: Results of the study were obtained by analysing data collected from 633 nine-year-old children in the 10th wave of the Panel Study on Korean Children(2017). The data were analyzed by descriptive statistics, correlation analysis and significance of mediated pathways using SPSS 23.0 and PROCESS macro 3.3. Results: First, children's self-esteem did not have mediational effects with respect to a supportive school environment and children's prosocial behavior. Second, children's happiness had mediational effects with respect to a supportive school environment and children's prosocial behavior. Lastly, a supportive school environment affects children's self-esteem, which affects children's happiness, thereby promoting children's prosocial behavior. Conclusion/Implications: In order to promote children's prosocial behavior, we should put emphasis on developing a supportive school environment, and increasing children's self-esteem and happiness. It is important that teachers treat children and classmates treat each other with a warm attitude so that they can value themselves and feel happiness in their lives.

The entrepreneurial activities of college students play a significant role in modern economic and social development, particularly as a solution to the changing economic landscape and youth unemployment issues. Introducing innovative ideas and technologies into the market through entrepreneurship can contribute to sustainable economic growth and social value. Additionally, the entrepreneurial intentions of college students are shaped by various factors, making it crucial to deeply understand and appropriately support these elements. To this end, this study systematically explores the importance and impact of role models through a multiple serial mediation analysis. Through a survey of 300 college students, the study analyzed how two psychological variables, growth mindset and entrepreneurial self-efficacy, mediate the influence of role models on entrepreneurial intentions. The presence and success stories of role models were found to enhance the growth mindset of college students, which in turn boosts their entrepreneurial self-efficacy and ultimately strengthens their entrepreneurial intentions. The analysis revealed that exposure to role models significantly influences the formation of a growth mindset among college students. This mindset fosters a positive attitude towards viewing challenges and failures in entrepreneurship as learning opportunities. Such a mindset further enhances entrepreneurial self-efficacy, thereby strengthening the intention to engage in entrepreneurial activities. This research offers insights by integrating various theories, such as mindset theory and social learning theory, to deeply understand the complex process of forming entrepreneurial intentions. Practically, this study provides important guidelines for the design and implementation of college entrepreneurship education. Utilizing role models can significantly enhance students' entrepreneurial intentions, and educational programs can strengthen students' growth mindset and entrepreneurial self-efficacy by sharing entrepreneurial experiences and knowledge through role models. In conclusion, this study provides a systematic and empirical analysis of the various factors and their complex interactions that impact the entrepreneurial intentions of college students. It confirms that psychological factors like growth mindset and entrepreneurial self-efficacy play a significant role in shaping entrepreneurial intentions, beyond mere information or technical education. This research emphasizes that these psychological factors should be comprehensively considered when developing and implementing policies and programs related to college entrepreneurship education.

This study was performed to evaluate the effect of increasing instream flow at Nonsancheon stream of Nonsan city by securing water storages in upstream reservoirs; Ge-ryong, Gyoung-cheon, Dae-dun, and Tab-jeong. The paralleled and cascaded upstream reservoir operations for 8 storage securing scenarios were considered to simulate daily streamflows at Nonsan station. Using Tab-jeong reservoir water storage, the DAWAST model's parameters were determined, and the verified result showed Nash-Schcliffe's coefficient of 0.666. Instream flows were analyzed to supply maximum $59.85Mm^3$ on an annually average from upstream reservoir storage securing scenarios. The storage securing set of 2 m heightened Ge-ryong, 5 m Dae-dun, and 1 m Tab-jeong showed that the additional secured water storages were $17.132Mm^3$ and instream flow at Nonsan station was increased to $2.183m^3/s$, 2 times of present condition.
