The purpose of this study was to identify the mediating effects of positive thinking in the relationship between emotional expressivity and public speaking anxiety. Participants were recruited from one university freshmen located in Gwangju city. Data were collected from 146 university freshmen. The self-reported questionnaire was used to assess the level of positive thinking, emotional expressivity, public speaking anxiety. The SPSS WIN 23.0 version program was used with Baron and Kenny's 3-Step mediating effect and Sobel test. It was examined whether there was a mediating effect of positive thinking on emotional expression and presentation anxiety. In the second stage, emotional expressivity showed a significant effect on presentation anxiety. In stage 3, emotional expressivity was not statistically significant in presentation anxiety, and positive thinking was statistically significant in presentation anxiety. Positive thinking had a total mediating effect(z=-4.57, p<.001) in the relationship between emotional expressivity and public speaking anxiety. To reduce the public speaking anxiety among university freshmen, it is necessary to develop interventions that enhance positive thinking in addition to providing emotional expressivity.

This study is to examine the effect of the thinking styles and character development efficacy of childhood educational teachers on their commitment to teaching with the intention of clarifying that these two factors of childhood educational teachers are important internal variables in enhancing their dedication to teaching, and to seek ways of finding thinking styles and character development efficacy appropriate for childhood educational teachers. Childhood educational teachers at nursing schools and kindergartens located in Daejeon, Chungnam, and Chungbuk were chosen as the study objects. The results are as follows: First, it turned out that childhood educational teachers's commitment to teaching was in close relation to their judicial, monarchy, totalitarian, internal, and liberal thinking styles. As for childhood educational teachers' character development efficacy, personal efficacy and dedication to teaching showed a high level of correlation. This indicates that as childhood educational teachers preferred certain thinking styles, their commitment to teaching also could be enhanced, and that as childhood educational teachers' personal efficacy was high, their commitment to teaching was enhanced as well. Second, as for the positive effect of childhood educational teachers' thinking styles and character development efficacy on their commitment to teaching, it turned out that such factors as judicial and internal thinking styles, common teacher efficacy, and personal teacher efficacy affected professional recognition, such factors as judicial, internal, conservative, liberal thinking styles and personal teacher efficacy influenced their affection for teaching, and such factors as legislative, monarchy, anarchic, and liberal thinking styles and personal teacher efficacy affected zeal.

The aim of this study was to investigate the relationship among the variables and the influence of academic self-efficacy and critical thinking disposition on the problem solving ability of nursing students. A descriptive research design was employed in this study. The participants were 404 sophomore nursing students in D city, who were surveyed between May 2 and May 20, 2016, using self-report questionnaire. The data were analyzed with SPSS WIN 21.0 using descriptive statistics, ANOVA, t-test, Scheffe test, Pearson's correlation coefficient, and multiple stepwise regression analysis. Significant correlations among the academic self-efficacy, critical thinking disposition, and problem solving ability were found. In academic self-efficacy and critical thinking disposition, there were significant differences in gender, academic credit, interpersonal relationship, and satisfaction with nursing as a major. The problem solving ability showed statistically significant differences in academic credit, interpersonal relationships, and satisfaction with nursing as a major. The regression model explained 51.7% of the effect on the problem solving ability. Academic self-efficacy and critical thinking disposition were factors influencing the problem solving ability of nursing students. Based on these results, to increase problem solving ability of nursing students, it will be necessary to develop an educational program and strategy for improving the academic self-efficacy and critical thinking disposition.

This study was investigate difference between critical thinking ability and disposition for the development of convergence. Data were collected from Nov. 5th to 16th 2012, using critical thinking instruments. There was no statistically significant difference in critical thinking ability according to scholastic standards and problem-based learning classes but difference according to level of education(senior students were higher than the other grades), clinical practice education and completion of critical thinking subject. There was no statistically significant difference in critical thinking disposition according to anything. Upon examining the correlation between critical thinking ability and disposition, it was significant, although small. Therefore we should separate for evaluation into two parts; critical thinking ability and disposition.

This study aimed to investigate the mediating effect of hope between stress and suicidal ideation of adolescents. For the study, 399 adolescents were surveyed at 10 cities of Korea from May to August in 2010. Main results of the study were in the followings. First, it was found out that stress of adolescents was positively correlated with suicidal ideation, hope was negatively correlated with suicidal ideation, and stress influenced more suicidal ideation than hope. Second, suicidal ideation of adolescents tended to be low, stress was in the middle level, and agency and pathways thinking of hope was higher than middle level. Third, it was proved that agency and pathways thinking of hope was mediated between stress and suicidal ideation of adolescents. Lastly, for the female adolescents living in the metropolitan and large cities, only agency thinking of hope was mediated but pathways thinking was not mediated. Policy implications for preventing and decreasing adolescent's suicide were suggested.

This study proposed a traffic accident prediction model developed based on administrative districts of Seoul. The model was to find the relationship between accident rates and the representative land usage of the districts (development density) - the higher the development density (building floor area) is, the higher the traffic accident rate is. The findings showed that traffic accident statistics differ from (1) residential building floor area, (2) commercial building floor area and (3) business building floor area.

The purpose of this study is to investigate the features of elementary students' intuitive thinking emerged during problem solving activities as it related to thermal phenomena, focusing on when intuitive thinking appears and how it is related to logical thinking. For this, we presented a problem related to thermal phenomena to nine 5th-grade students, and examined how students' thinking emerged in the activities. We conducted clinical interviews to investigate the thinking process of students. The results of this study are as follows. First, students made their own solutions and justified it later during the emergence process of intuitive thinking. It was also found that students connected concrete materials and abstract concepts intuitively. They solved the problem by making predictions even when information is insufficient. Second, it was shown that intuitive thinking can emerge through the intended strategies such as drawing a mental image, thinking from a different perspective, and integrating methods. These results, which are related to the students' intuitive thinking has received little attention and will be the basis for helping students in the context of discovery of their problem solving activities.

교통사고 예측은 차량의 블랙박스 동영상을 통해 사고 발생을 최대한 빨리 예측하는 것을 목표로 한다. 이는 안전한 자율주행 시스템을 보장하는 데 중요한 역할을 한다. 다양한 교통 상황과 카메라의 제한된 시야로 인해 프레임에서 사고 가능성을 조기에 관찰하는 것은 어려운 도전이다. 예측의 핵심 기술은 객체의 시공간 관계를 학습하는 것이다. 본 논문에서는 블랙박스 동영상에서 사고 예측을 위한 계산 모델을 제안한다. 이것을 사용하여 사고 예방을 강화한다. 이 모델은 사고 위험에 대한 운전자의 시각적 인식에서 영감을 받았다. 객체 탐지기는 동영상 프레임에서 다양한 객체를 탐지한다. 탐지한 객체는 노드 생성기와 특징 추출기 동시에 통과한다. 노드 생성기에서 생성한 노드는 GCN 실행기를 사용한다. GCN 실행기는 각 프레임에 대한 객체의 3D 위치 관계를 계산한 후 공간 특징을 취득한다. 동시에 공간 특징과 특징 추출기에서 얻은 객체의 특징은 GRU 실행기로 보내진다. GRU 실행기 안에 시공간 특징을 암기하고 분석하여 교통사고 확률을 예측한다.
