섬진강댐은 100년빈도 홍수에 대응토록 설계되어 홍수조절 능력이 타 다목적댐 대비 상대적으로 취약함에 따라 댐운영 체계 개선이 필요하다. 이에따라 K-water는 홍수시 피해를 최소화 할 수 있도록 댐운영과 관련한 홍수대응 체계를 개선하였다. 주요 개선대책은 섬진강 홍수조절용량 추가확보, 홍수기 강우특성을 고려한 홍수조절, 하류주민 및 기관과 소통에 기반한 정보 공유체계 확립, 디지털 트윈 기반 댐 운영 의사결정시스템 구축이다. 섬진강댐의 건설홍수조절용량은 3천만m³으로, 타 다목적댐 설계빈도인 200년 대비 홍수대응 능력이 미흡하다. 이에따라, 섬진강댐은 '21.1월부터 '22.12월까지 홍수기 제한수위를 기존 197.7m에서 2.5m 낮춘 194.0m로 시범운영하고 있다. 이를통해 기존 3천만m³에서 9천만m³까지 6천만m³의 홍수조절용량을 추가 확보하였다. 이와 연계하여 홍수기 동안 섬진강댐 운영수위 기준을 별도 수립하여 홍수기 전·후반으로 나누었으며, 전반기(~7/31)는 '20년 홍수상황에서 발생한 더블피크 집중호우(360mm)에 대응가능한 홍수조절능력을 확보하고, 후반기(8/1~)는 홍수조절능력을 최대한 확보함과 동시에 차년도 용수공급을 대비할 수 있도록 운영수위를 개선하였다. 그간 수문방류 정보는 '댐 관리규정'에 따라 방류개시 3시간 전까지 방류계획을 하류지역의 지자체 및 주민에게 통보하였으나, 하류주민들이 충분히 사전준비하기에 시간적으로 부족하다는 의견을 제시함에 따라 수문방류 24시간전 사전 안내토록 '수문방류 예고제'를 도입, 시행하였다. '댐 홍수관리 소통회의'를 통해 댐 운영기관-정부기관-주민이 댐 운영에 대한 전반에 대해 함께 공유하고 운영 제약사항 및 개선사항을 공동 발굴하여 대책을 마련하는 체계를 구축하였다. 댐 운영 개선사항과 더불어 댐방류 의사결정시, 실시간 하류하천 상황에 대한 확인이 어려움에 따라, 3D기반 의사결정 지원시스템인 Digita Twin Platform을 개발 및 구축하여 '22년부터 섬진강댐 운영에 시범적용을 추진하고자 한다.

This study aimed to explore the effects of private tutoring expenses, parents' monitoring affection, their children's learning value and self-regulated learning abilities on middle-school boys' and girls' English Math academic achievement. The subjects were the 3rd middle-school 1,123 students taking the private tutoring of English and Math who participated in the Korea Child Youth Panel Surveys(KCYPS). The data were analyzed with descriptive statistics, correlations and hierarchical regressions. The main results of this study were as follows. Firstly, regardless of middle-school students' sex, as monthly average private tutoring expenses were more, the levels of parents' monitoring, and their children's learning value self-regulated learning abilities were higher, so middle-school students' academic achievement was higher. Secondly, regardless of middle-school students' sex, their self-regulated learning abilities were the highest predictors of English Math achievement. Also, their learning value and parents' monitoring influenced middle-school boys' English Math achievement in order. On the other hand, monthly average private tutoring expenses influenced middle-school girls' English Math achievement. Furthermore there were no moderating effects of parents' monitoring affection, their children's learning value and self-regulated learning abilities between monthly average private tutoring expenses and middle-school boys' and girls' English Math achievement. Finally, based on the results, the importance of parents and Home Economics was suggested in attaining middle-school students' higher academic achievement. Especially, Home Economics can play an important role of enhancing middle-school students' self-regulated learning abilities and learning value necessary for middle-school students' higher academic achievement.

This study was conducted to identify the moderating effect of rejection sensitivity in the relationship between depression and interpersonal competence in university students. Data collection was conducted from September to October 2020, and 184 students attending universities in D City and C province in Korea completed the self-report questionnaire. The collected data were subjected to Pearson's correlation and hierarchical regression analysis using the SPSS 26.0 program. In this study, depression and rejection sensitivity of university students were identified as significant influencing factors on interpersonal competence, and rejection sensitivity confirmed a moderating effect on the relationship between depression and interpersonal competence. The results of this study provide basic data on the mechanisms of action between depression, rejection sensitivity, and interpersonal competence of university students, and suggest that elements of depression and rejection sensitivity should be included in intervention programs to improve university students' interpersonal competence. Based on the results of this study, we suggest a study for the development of an effective individualized intervention program that can improve the interpersonal competence of university students.

This study investigates the relationship between self-regulated learning ability, learning style and the degree of learning participation in on-line learning. After a four-year university course was constructed in an on-line learning environment and open on-line courses for a semester, in order to recognize the degree of learning participation, an analysis of system log files and notification of the number of bulletins were performed. The result indicates that self-regulated learning ability has a static correlation with the degree of learning participation, and that learning style is not statistically meaningful. Also, the relationship between self-regulated learning ability and learning style was not statistically meaningful. As to the learning style, researchers expected most students would be convergent, but 63.4 per cent of students (52 students) displayed dispersion. In conclusion, when on-line learning is designed, a proper self-regulated learning strategy will help better learning achievement.

This study examines how kindergarten teachers' empathy and efficacy in enlisting parental involvement predict perceived parent-teacher relationships and teacher burnout. It also investigates whether teacher efficacy in enlisting parental involvement moderates the relationship between kindergarten teachers' empathy, perceived parent-teacher relationships, and teacher burnout. A total of 208 public and private kindergarten teachers employed in the Chungbuk area participated in a survey, and the data were analyzed using JAMOVI (version 1.6.23). There were three major findings. First, both kindergarten teachers' empathy and efficacy in enlisting parental involvement positively predicted perceived parent-teacher relationships. Second, there was a significant interaction effect between teacher empathy and teacher efficacy in enlisting parental involvement on perceived parent-teacher relationships. Specifically, when teacher efficacy in enlisting parental involvement was high (M+1SD), teacher empathy significantly positively predicted parent-teacher relationships. By contrast, when teacher efficacy in enlisting parental involvement was average or low (M-1SD), the effect of teacher empathy on the perceived parent-teacher relationships was not significant. Third, both kindergarten teachers' empathy and teacher efficacy in enlisting parental involvement negatively predicted teacher burnout, but there was no significant interaction effect between teacher empathy and teacher efficacy in enlisting parental involvement on teacher burnout. This study identified the role of teacher efficacy in enlisting parental involvement within the context of kindergarten teacher-parent relationships and teacher burnout. It confirmed that the effect of teacher empathy on parent-teacher relationships is moderated by the level of teacher efficacy in enlisting parental involvement.
