The recognition of human emotional state is one of the most important components for efficient human-human and human- computer interaction. In this paper, four emotions such as fear, disgust, joy, and neutral was a main problem of classifying emotion recognition and an approach of visual-stimuli for eliciting emotion based on physiological signals of skin conductance (SC), skin temperature (SKT), and blood volume pulse (BVP) was used to design the experiment. In order to reach the goal of solving this problem, half-against-half (HAH) multi-class support vector machine (SVM) with Gaussian radial basis function (RBF) kernel was proposed showing the effective techniques to improve the accuracy rate of emotion classification. The experimental results proved that the proposed was an efficient method for solving the emotion recognition problems with the accuracy rate of 90% of neutral, 86.67% of joy, 85% of disgust, and 80% of fear.

The purpose of this study was to examine the proximity of clothing to self and proximity of cosmetic to self by Degree of Cosmetics. The scales used in this study include the arranged on the basis of Sontag (1978) 's study for proximity of clothing to self, and the scale developed by the researcher for proximity of cosmetic to self. The subjects of this study were 885 adult women in Taegu. The data collected were analyzed by using MANOVA, ANOVA, and the Cronbach a was also applied. The results of this study were summarized as follows: 1. The persons with high degree of cosmetics showed high degrees of joy of change, self-value expression, novelty, self-consciousness and consciousness to others in the sub-factors of proximity of clothing to self, while there was not significant difference in physical satisfaction. 2. The persons with high degree of cosmetics showed high degrees of social confidence, skin care, joy of change, self-satisfaction, instrument of disguise in the sub-factors of proximity of cosmetic to self.

A driver's emotion is a very important factor of safe driving. This paper classified a driver's emotion into 3 major emotions, can be occur when driving a car: Surprise, Joy, Tired. And It evaluated the classifier using Hidden Markov Models, which have observation sequence as bio-signals. It used the 2-D emotional plane to classfiy a human's general emotion state. The 2-D emotional plane has 2 axes of pleasure-displeasure and arsual-relaxztion. The used bio-signals are Galvanic Skin Response(GSR) and Heart Rate Variability(HRV), which are easy to acquire and reliable. We classified several moving pictures into 3 major emotions to evaluate our HMM system. As a result of driving simulations for each emotional situations, we can get recognition rates of 67% for surprise, 58% for joy and 52% for tired.

This study was conducted in order to develop a Children's Playfulness Rating Scale(CPRS) and to analyze it in terms of item discrimination, validity, and reliability. The participants in this study consisted of 861 parents whose children were aged from three to six years old. The item discrimination, determined by comparing the highest and lowest group using ${\chi}^2$, Cramer's V, was found to be satisfactory. The reliability of factors, as measured by Cronbach's ${\alpha}$, ranged from .85 to .95. The results of factor analysis identified 4 factors and 35 items were then selected from the 45 items in the original scale. The four factors identified were as follows; (1) leading participation (2) cognitive flexibility (3) expression of joy (4) voluntary full immersion. Concurrent validity was also established by using correlations between the CPRS and CPS(Children's Playfulness Scale). In conclusion, these results demonstrated that the Children's Playfulness Rating Scale is both reliable and valid.

Customer delight is critical to firm's success in today's competitive environment. This importance has led marketing scholars and practitioners to recommend that firms improve their customers' delight because it is a key to customer loyalty. However, researchers and practitioners have also begun to express concern on the process that underlies customers' delight-loyalty relationship. The purpose of this paper is to investigate this question: 'Does it really matter that firms delight to their customers to achieve greater customer loyalty?' The results from one experiment using a scenario method and the data collected by questionnaire real that delighted customers(offered an unexpected gift) were significantly more warmth, joy and loyalty than satisfied respondents(offered a free gift). The warmth dimension of delight influenced positively on loyalty in satisfied customer group. In delighted customer group, both warmth and joy influenced positively on loyalty.

This study examined the affective prosodic characteristics observed from the children with cochlear implant (CI, hereafter) and normal hearing (NH, hereafter) along with listener's perception on them. Speech samples were acquired from 15 normal and 15 CI children. 8 SLPs(Speech Language Pathologists) perceptually evaluated affective types using Praat's ExperimentMFC. When it comes to the acoustic results, there were statistically meaningful differences between 2 groups in affective types [joy (discriminated by intensity deviation), anger (by intensity-related variables dominantly and duration-related variables partly), and sadness (by all aspects of prosodic variables)]. CI's data are much more louder when expressing joy, louder and slower when expressing anger, and higher, louder, and slower when it comes to sadness than those of NH. The listeners showed much higher correlation when evaluating normal children than CI group(p<.001). Chi-square results revealed that listeners did not show coherence at CI's utterance, but did at those of NH's (CI(p<.01), normal(p=.48)). When CI utterances were discriminated into 3 emotional types by DA(Discriminant Analysis) using 8 acoustic variables, speed related variables such as articulation rate took primary role.

This research employs the grounded theory approach among various qualitative methodologies in order to reach a deep understanding of both the experiential process that children undergo in block play and the essential meaning of it. The objects of this study are 22 children(female 7, male 15) in a 5-year-old class of K kindergarten at Guro district, Seoul. The result of this research shows that first, children take pleasure in block play because of the delight and sense of accomplishment in building, the joy in demolishing, and the happiness of embracing the world through dramatic play with building structures. Second, the characteristics of children's block play are popular subject of the play, decision of the subject, impromptu transformation and elaboration of building structures, and flow of the play according to friend/non-friend relationship. Third, the implicit rules shared by children have more significant influences upon the block play than the agreed rules at the beginning of semester.

The purpose of this study was to find out the mutual relations of self-efficacy proximity of cosmetic to self and proximity of clothing to self. The researcher used the scale of Sherer Mercadante Maddux Rrentice-Dunn Jacobs and Rogers(1982) for a general and social self-efficacy. The scale of Ryckman Roddins Thorton and Cantrell(1982) for a physical self-efficacy. The researcher corrected and supplemented the tools on the basis of Sontag(1987)'s scale for proximity of clothing to self. The researcher developed proximity of cos-metic to self. The subjects of this study were 172 girl students in the university. The research was analyzed by MANOVA Scheff post hoc test and Cronback a. The Results of this study were as follows: 1. The person who had a higher self-efficacy was higher in the hoy and skin-carve in the sub-causes of proximity of cosmetic to self. There was no difference in social-confidence self-satisfaction and disguise. 2. The person who had a higher self-efficacy was high in the self-expression and the physi-cal satisfaction in the sub-causes of proximity of clothing to self. There was no difference in the joy self-consciousness the consciousness of others and the novelity. 3. The person who had a higher proximity of cosmetic to self was higher in the joy, self-ex-pression and self-consciousness of others and the novelity. There was no difference in the physical satisfaction.
