The study is to examine how facial EMG responses change when children experience a positive emotion(happiness) and a negative emotion(fear). It is to prove that the positive emotion(happiness) could be distinguishable from the negative emotion(fear) by the EMG responses. Audiovisual film clips were used for evoking the positive emotion(happiness) and the negative emotion(fear). 47 children (11-13 years old, 23 boys and 24 girls) participated in the study Facial EMG (right corrugator and orbicularis oris) was measured while children were experiencing the positive or negative emotion. Emotional assessment scale was used for measuring children's psychological responses. It showed more than $85\%$ appropriateness and 3.15, 4.04 effectiveness (5 scale) for happiness and fear, respectively. Facial EMG responses were significantly different between a resting state and a emotional state both in happiness and in fear (p<001). Result suggests that each emotion was distinguishable by corrugator and orbicularis oris responses. Specifically, corrugator was more activated in the positive emotion(happiness) than in the negative emotion(fear), whereas orbicularis oris was more activated in the negative emotion(fear) than in the positive emotion(fear).

In this paper, a database is collected for extending the speech synthesis model to a model that synthesizes speech according to emotions and generating facial expressions. The database is divided into male and female data, and consists of emotional speech and facial expressions. Two professional actors of different genders speak sentences in Korean. Sentences are divided into four emotions: happiness, sadness, anger, and neutrality. Each actor plays about 3300 sentences per emotion. A total of 26468 sentences collected by filming this are not overlap and contain expression similar to the corresponding emotion. Since building a high-quality database is important for the performance of future research, the database is assessed on emotional category, intensity, and genuineness. In order to find out the accuracy according to the modality of data, the database is divided into audio-video data, audio data, and video data.

The present study describes a combination method to recognize the human affective states such as anger, happiness, sadness, or surprise. For this, we extracted emotional features from voice signals and facial expressions, and then trained them to recognize emotional states using hidden Markov model (HMM) and neural network (NN). For voices, we used prosodic parameters such as pitch signals, energy, and their derivatives, which were then trained by HMM for recognition. For facial expressions, on the other hands, we used feature parameters extracted from thermal and visible images, and these feature parameters were then trained by NN for recognition. The recognition rates for the combined parameters obtained from voice and facial expressions showed better performance than any of two isolated sets of parameters. The simulation results were also compared with human questionnaire results.

This study is to find a service that improves the subjective happiness of cancer patients that receive radiation therapy. One hundred and one cancer patients undergoing radiation therapy were enrolled in the survey to verify the self-consciousness and symptom distress that could affect the subjective happiness. Independent t-test, one-way analysis of variance, and Pearson correlation were conducted with the SPSS 20.0 program. Symptom distress of cancer patients undergoing radiation therapy showed highest in the order of fatigue, appearance changes, dizziness, loss of appetite, and sleep disorders. And lower symptom distress, higher private self-consciousness were significantly correlated with higher subjective happiness among patients receiving radiation therapy for cancer. Study findings reflect the necessity of an integrative approach combining physical, psychological and emotional interventions during a radiotherapy period. For this cause, it would be necessary to supplement previously existing service programs and organize a patient-friendly system that could affiliate regional cancer centers or Public health centers with the hospitals in which the patients are being treated.

The appropriate interpretation of social cues is a crucial ability for everyday life. While processing socially relevant information, beyond the low-level physical features of the stimuli to emotional information is known to influence human cognition in various stages, from early perception to later high-level cognition, such as working memory (WM). However, it remains unclear how the influence of each type of emotional information on cognitive processes changes in response to what has occurred in the processing stage. Past studies have largely adopted face stimuli to address this type of research question, but we used a unique class of socially relevant motion stimuli, called biological motion (BM), which depicts various human actions and emotions with moving dots to exhibit the effects of anger, happiness, and neutral emotion on task performance in perceptual and working memory. In this study, participants determined whether two BM stimuli, sequentially presented with a delay between them (WM task) or one immediately after the other (perceptual task), were identical. The perceptual task showed that discrimination accuracies for emotional stimuli (i.e., angry and happy) were lower than those for neutral stimuli, implying that emotional information has a negative impact on early perceptual processes. Alternatively, the results of the WM task showed that the accuracy drop as the interstimulus interval increased was actually lower in emotional BM conditions than in the neutral condition, which suggests that emotional information benefited maintenance. Moreover, anger and happiness had distinct impacts on the performance of perception and WM. Our findings have significance as we provide evidence for the interaction of type of emotion and information-processing stage.

Purpose: The purpose of this study is to examine the effects of clinical art therapy programs utilized at schools on adolescents' suicidal thoughts and stress relief and to validate their effectiveness as a type of adolescent suicide prevention program. Methods: 12 sessions of clinical art therapy for youth suicide prevention were provided, once a week for 90 minutes, for 20 students at five middle schools in Seoul who were at high risk of committing suicide. By using the paired sample t-test, the study presented qualitative data on the analysis of pre- and post- questionnaires and on the subjects' EEG test and saliva test. Results: First, through the clinical art therapy program, the subjects' happiness index improved significantly while their scores of depression and suicidal ideation (suicidal thoughts) decreased. Second, in the EEG and saliva test conducted after the art therapy sessions, emotional stability increased and stress was reduced significantly. Third, according to the results of pre- and post- K-HTP tests and individual activities, the subjects started to recognize the seriousness of suicide and show emotional stability and positive changes in overall attitudes, valuing the rights and life of their own 'precious selves' (self respect). Conclusion: The results of this study indicate that the clinical art therapy program is significantly effective at preventing suicidal ideation by reducing suicidal impulses and depression, by increasing the happiness index, which can serve as a protective factor against suicide, and by increasing emotional stability while reducing stress. Based on the results, there is a need to develop policy measures regarding art therapy programs which can be utilized at schools.
