  • In this paper, we propose an study of the facial emotion recognition considering the dynamical variation of emotional state in facial image sequences. The proposed system consists of two main step: facial image based emotional feature extraction and emotional state classification/recognition. At first, we propose a method for extracting and analyzing the emotional feature region using a combination of Active Shape Model (ASM) and Facial Action Units (FAUs). And then, it is proposed that emotional state classification and recognition method based on Hidden Markov Model (HMM) type of dynamic Bayesian network. Also, we adopt a Harmony Search (HS) algorithm based heuristic optimization procedure in a parameter learning of HMM in order to classify the emotional state more accurately. By using all these methods, we construct the emotion recognition system based on variations of the dynamic facial image sequence and make an attempt at improvement of the recognition performance.

  • This study was conducted to prove the structural relation of how effective teaching methods in remote design courses affects learning participation and academic achievement. The data was acquired and analyzed with case study of design classes. The scale of remote practical classes, learning participation and academic achievement were measured and the data acquired were verified using SPSS and AMOS to prove the influence. The results are as follows. First, using the lecture method in remote classes appeared to have a negative effect on cognitive, emotional, and behavioral participation. Second, flipped learning had a positive effect on cognitive and emotional participation but no effect was found on behavioral participation. Third, PBL had a positive effect on all emotional, cognitive, and behavioral participation. Fourth, videos did not have any meaningful effect on cognitive and emotional participation but had a positive effect on behavioral participation. Fifth, only cognitive participation had a positive effect on academic achievement, but no relations were found between emotional and behavioral participation and academic achievement. These results suggest that it is needed combining actual classes with the PBL method and flipped learning and creating different programs.

  • This study was conducted to develop and apply an out-of-school STEAM program model based on Social-Emotional Learning (SEL) for underprivileged students in the lower grades. To this end, a STEAM program based on SEL was developed, with the following characteristics. First, by integrating traditional STEAM learning elements and SEL elements, a structured program was designed with consistent stages, including mindfulness meditation→present an authentic situation→creative design→emotional experiences→reflection. Second, the program was structured so that elementary school students could develop mathematical thinking and scientific inquiry skills in problem-solving situations in daily life. Third, the detailed themes for each STEAM program involved storytelling-based problem situations, as well as activities centered on play and sympathy to reflect the educational needs of underprivileged students. From these characteristics, a total of five programs were developed and applied to 16 teachers and 354 lower-grade elementary school students in 16 community children centers nationwide. The results were as follows. First, while students' satisfaction with the STEAM program was 4.16, there were no significant differences in STEAM satisfaction according to gender. Second, while all students' interest and self-efficacy, which was one of sub factors of STEAM attitude, were significantly improved, no significant difference was seen in STEAM attitudes according to gender. Third, although students' SEL competencies were not significantly improved, relationship skills, which were among the sub factors of SEL competencies, were significantly improved, and there were no significant differences in SEL competencies according to gender. From these results, a discussion on the effect of the out-of-school STEAM program for underprivileged students and directions for follow-up studies was suggested.

  • This study examined affective representation by analyzing physiological responses measured using wearable devices and affective ratings in response to emotional videos. To achieve this aim, a published dataset was reanalyzed using multidimensional scaling to demonstrate affective representation in two dimensions. Cross-participant classification was also conducted to identify the consistency of emotional responses across participants. The accuracy and misclassification in each emotional condition were described by exploring the confusion matrix derived from the classification analysis. Multidimensional scaling revealed that the represented objects, namely, emotional videos, were positioned along the rated valence and arousal vectors, supporting the core affect theory (Russell, 1980). Vector fittings of physiological responses also showed the associations between heart rate acceleration and low arousal, increased heart rate variability and negative and high arousal, and increased electrodermal activity and negative and low arousal. Using the data of behavioral and physiological responses across participants, the classification results revealed that emotional videos were more accurately classified than the chance level of classification. The confusion matrix showed that awe, enthusiasm, and liking, which were categorized as positive, low arousal emotions in this study, were less accurately classified than the other emotions and were misclassified for each other. Through multivariate analyses, this study confirms the core affect theory using physiological responses measured through wearable devices and affective ratings in response to emotional videos.

  • During human development, rapid emotional growth develops in infancy, and emotional regulation affects positive emotional development. Therefore, it is important for infants to learn how to control their emotions in infancy. In this study, we propose music-based media content that can improve the emotional regulation ability of infants. In other words, this study suggests a projector-based interactive content that plays various musical instruments through movement of the body following the music on the basis of the Eurhythmics education. Children were asked to perform five instruments: bass, drums, tambourines, castanets, and maracas in their physical movements using their hands, arms, and legs, so that physical activity had a positive impact on the child's emotional regulation. This music - based interactive content is expected to provide an environment that can help improve the emotional regulation by concentrating the attention of children.

  • The purpose of this study wasto analyze the factors that enhance their learning achievement in a fieldtrip environment. For this academic goal, we analyzed a pattern of fieldtrip-related perception and attitudes of 19 science-talented students who participated in the 2007 KESO winter school. As for the perception type, the result of analysis showed that the science-talented students understood a fieldtrip as an experimental inquiry from an inquiry perspective, and that their understanding about a fieldtrip was based on anthropocentrism, positivism and instrumentalism from a science philosophy perspective. Regarding theattitudes type, the result revealed that the purpose of the winter school was mainly to learn knowledge in earth science, and that there was a significant tendency for the participating students to become a future scientist more eagerly than their parents expected. Students' fieldtrip-related academic self-concept was mostly positive while the participants experienced both positive and negative emotions.
