This study aims to identify the structural relationship between mastery-approach goal orientation, instructor support, problem solving, collaborative skills, and course satisfaction among students who participated in project-based learning. To achieve the purpose of this research, researchers have conducted surveys between June and December in 2019. A total of 283 cases were selected for analysis. According to the study, mastery-approach goal orientation and instructor support have positive effects on problem solving and course satisfaction. Instructor support has positive effects on collaboration skills, and problem solving has positive effects on collaboration skills and course satisfaction. Also, the mediating effect of problem solving in the relationship among mastery-approach goal orientation, instructor support, collaboration skills, and course satisfaction was found to be statistically significant. However, the path between mastery-approach goal orientation and collaboration skills was not statistically significant. Based on these findings, academic and practical implications were suggested.

This study aims to explore the structural relationships among experiences of being heard in home and school settings, self-esteem, and human rights awareness. Among the 2017 NYPI Cross-sectional Survey on the Rights of Youth & Children, 6,405 middle and high school students (47.8% females) were used to conduct a structural equation modeling using Mplus. It was found that children who experience being heard in the home or school display higher levels of self-esteem and awareness of human rights. It was also found that self-esteem is more likely to increase awareness of human rights. Self-esteem was also found to mediate the pathway between the experience of being heard at home or school and human rights awareness. In addition, there was no significant difference in path coefficients depending on whether they received human rights education. Practical implications for promoting home and school environments where children's opinions can be heard were discussed.

The purpose of this study is to determine how the factors that form the spatiality of an idle space affect the behavioral intention of tourists, and to confirm the role of local participation between the spatiality-forming factors and behavioral intentions. For this purpose, data from travelers was gathered and the study model was put to the test. As a result of the study, it was confirmed that physical factors, behavioral factors, and psychological factors had a significant effect on the intention of tourists. In addition, it was confirmed that local participation partially plays a mediating role between the spatiality-forming factors and behavioral intentions. According to the results of the study, the necessity of local participation and the measures were discussed when using the idle space, and it was suggested that additional research needs to be carried out targeting various idle spaces.

This study examined significant differences in the impact of workplace bullying on emotional depletion and organizational commitment, and used 400 questionnaires to examine whether there would be significant differences depending on social support. As an analysis method, we used SPSS 24 for sample characteristics, SmartPLS 3 statistical programs for verifiable factor analysis, reliability and validity, path analysis, and structural equation models. Studies have shown that bullying in the workplace affects significant positive (+) for emotional depletion, and that emotional depletion affects significant negative (-) for tissue commitment. The influence relationship between workplace bullying and tissue commitment was partially mediated in the direction of wealth (-), and the effect of emotional depletion on tissue immersion was shown to be significant differences in the control of social support. Implications are that bullying in the workplace affects emotional depletion, so corporate efforts to prevent bullying are urgently needed, suggesting that employees can improve their organizational commitment, by using a system or community that can promote communication with their bosses.

The purpose of this study was to examine the effect of parent-child interactions on children's academic performance focusing on the mediating effect of children's executive function difficulty. The data for this study were drawn from the Panel Study on Korean Children(PSKC). The participants were 559 children of elementary school and their families from 8th wave(1^st graders), 9th wave(2^nd graders), and 10th wave(3^rd graders) of PSKC. The data were analyzed with structural equation modeling. The results of this study were as follows. First, mother-child interaction and father-child interaction didn't have a significant direct effect on children's academic performance. Second, mother-child interaction had a significant positive indirect influences on academic performance through children's executive function difficulty. The results of this study indicated that mother-child interaction and children's executive function difficulty are important for children's academic performance.

This study designed a research model to analyze the relationship between organizational commitment and work performance for outsourcing workers. The path relationship was analyzed using the PLS-SEM of the sample collected through the survey. As a result of the study, organizational support perception had a direct effect on the work performance of outsourcing workers, and the company commitment and customer company commitment had a mediating effect. In addition, it was confirmed that the workers showed dual commitment to the company and the customer company, and the organizational commitment to both companies was complementary. It was also suggested that the outsourcing company's organizational support activities are more important for improving the work performance of workers.

This study aimed at examining the mediation effects of depressive symptoms on the association between social activity participation and marital satisfaction among couples in later life. The study included 1,196 married couples aged 65 or above who participated in the 7th Korean Longitudinal Study of Aging in 2018. The study variables were husbands' and wives' social activity participation, marital satisfaction, and depressive symptoms. Covariates were individual age, education level, subjective health, couples' household income, and number of children. The Actor-Partner Interdependence Mediation Model (APIMeM) and bootstrapping techniques were used to test the significance of the mediating impacts of depressive symptoms based on the dyadic data structure. The results showed that for both husbands and wives, active participation in social activities had significant effects on increasing marital satisfaction through lowering depressive symptoms. However, only the participation of husbands in social activities was positively associated with their own marital satisfaction by reducing their own and their partner's depressive symptoms. These findings suggest that the active social participation of individuals salient for promoting the quality of marital relationships in later life, particularly for preventing their own and their spouse's depressive symptoms.

우리나라 농촌 지역의 농업용저수지는 유역면적이 작고 홍수 도달시간이 짧아 홍수 대응에 어려움이 있으며, 대부분의 농업용저수지는 용수공급 목적으로 건설되어 홍수 대응능력이 부족한 실정이다. 한국농어촌공사는 수자원, 재난재해 등 농촌용수 관련된 다양한 정보의 통합관리를 위한RAWRIS(Rural Agricultural Water Resource Information System)을 운영하고 있으나, 소하천 및 농촌 지역의 홍수 피해 저감에 대한 관리와 노력은 도시 지역의 대하천 유역과 비교하여 여전히 부족한 실정이다. 이에 본 연구에서는 농촌지역의 과학적 재해관리를 위해 RAWRIS의 홍수량 산정기술을 개선하고, 저수지 홍수예경보에 필요한 기상청 초단기 강우예측자료의 활용성을 검토하고자 하였다. 이를 위해 농어촌공사에서 관리하는 농업용저수지 중 홍수배제시설인 레디얼게이트가 설치된 농업용저수지 30개소를 대상으로 해당 저수지의 수위계측 정보, 수문 방류 정보 등 저수지 홍수관리 현황을 조사하였다. 다음으로 농어촌공사가 운영 중인 RAWRIS의 홍수량 산정과정을 검토하여, 기존 RAWRIS에 CN값이 미설정된 저수지 유역의 CN값을 설정하였으며, 유역의 강우량 및 유효우량 산정 알고리즘 개선하고 저수지 유역별 강우-유출모형의 대표 매개변수를 제시하였다. 마지막으로 기상청에서 제공하고 있는 초단기 강우예측자료의 활용성 평가를 위해 기상청 강우예측자료와 저수지 유역의 면적평균강우를 비교하였으며, 예측 및 관측강우에 의한 홍수유입량을 산정하여 그 결과를 비교하였다. RAWRIS 홍수량 산정기술의 개선 효과를 검토한 결과, 예당저수지의 경우에는 첨두유량백분율 오차가 최대 50 % 이상, 결정계수(R2)가 최대 0.6 이상 개선된 것으로 나타났다. 다음으로 초단기 강우예측자료의 활용성을 평가하기 위해 RAWRIS에 제공되는 기상청 강우예측자료와 관측강우자료을 비교한 결과, 초단기 예측강우자료는 정량적, 정성적 신뢰도의 문제가 있어, 농업용저수지 홍수예측시스템에 그대로 적용하는데에는 무리가 있는 것으로 나타났다.

Effectiveness of corporate promotion using SNS will be meaningful from theoretical and practical perspectives. This study attempts to explore the implications of running corporate ambassador programs composed of university students, different from previous studies focused mainly on celebrity influencers. To this end, the research model was generated and the hypotheses were tested by the responses of 287 subjects who received promotional messages from university student ambassadors of a public corporation. Research findings confirmed that ambassador characteristics (intimacy, expertise) had a significant influence on corporate promotion by mediating SNS information characteristics (information provision, information playfulness, and information reliability). Furthermore, it is found that MZ generation perceived the higher intimacy, the higher information playfulness, while the older generation perceived the higher expertise, the higher information reliability. In order to generalize these research findings, further research considering more diverse demographic characteristics is necessary.

This study used the data of students from the 6th grade to the 3rd grade of middle schoolin the Korean Educational Longitudinal Study 2013 and classified them into subgroups with similar longitudinal changes in math academic achievement. In addition, the influence of longitudinal changes in the group's academic self-concept and teachers and parents academic support on the longitudinal changes in math academic achievement were analyzed, either directly or indirectly. As a result of the analysis, it was found that the academic self-concept of each group had a positive influence on the academic achievement in mathematics. In addition, the academic support of teachers and parents was found to have a positive influence on the academic achievement in mathematics through the mediating of the academic self-concept. In terms of direct and indirect influence on academic self-concept and math vertical scale scores, it was found that teachers' academic support had more influence than parents' academic support. The educational implications of these points were discussed.
