Facial expression is an effective tool to express human emotion. In this paper, a facial expression analysis method based on the base faces and their blending ratio is proposed. The seven base faces were chosen as axes describing and analyzing arbitrary facial expression. We set up seven facial expressions such as, surprise, fear, anger, disgust, happiness, sadness, and expressionless as base faces. Facial expression was built by fitting generic 3D facial model to facial image. Two comparable methods, Genetic Algorithms and Simulated Annealing were used to search the blending ratio of base faces. The usefulness of the proposed method for facial expression analysis was proved by the facial expression synthesis results.

We surveyed to assess the impact of the mood states and sentiments resulting from forest experience on the school life satisfaction of Korean boarding middle school students (n=90). The average mood state score was 2.32 on a scale of 1-5, with the subscale of vigor scoring the highest (3.19). The average sentiment score was 3.08, with the subscale of subjective happiness scoring the highest (3.08). The average school life satisfaction score was 3.66, with the subscale of interpersonal relationships scoring the highest (3.91). The mood states resulting from forest experience explained 39.6% of the variance in school life satisfaction, and the regression model showed a significant fit (F=9.077, p<0.001). Similarly, sentiments resulting from forest experience explained 47.4% of school life satisfaction, with the regression model showing a significant fit (F=10.569, p<0.001). It can be concluded that forest experience positively impacts the school life satisfaction of Korean boarding middle school students.

This study examined the difference between the deaf and hearing adolescents of experiencing emotions and the intensity levels of expressing them. Three different video clips were used to induce pleasure, anger, and sadness. While watching the clips, facial expressions of the participants were recorded. The experienced emotions were measured by a self-report method, and the third person rated participants' expressed emotions based upon the recorded facial images. Two groups (deaf and hearing) were compared if those two groups shared the same experienced emotions, and whether the ratings scored by the third person corresponded with the self-rated scores. There was no significant difference in experienced emotion and its intensity level. However, hearing adolescents showed more intensive responses of pleasure than they reported, while deaf adolescents showed less intensive expressions of happiness than they reported themselves. Thus, hearing people might not be able to detect and fully comprehend how the deaf feel in general circumstances. This further indicates that the deaf adolescents cannot get enough supports from the hearing people when they express their feelings, and consequently, have a possibility of causing misunderstandings, conflicts, or even a break in relationships.

Objectives : The Self-Assessment Manikin (SAM) developed by Bradley and Lang is a non-verbal pictorial assessment tool that measures human emotion and has been widely used. However, the pictures in SAM have not been easy for Korean subjects to understand or relate to. The authors developed a new manikin (Emotional Valence and Arousal Manikin, EVAS) modeling it after Korean faces while modifying and standardizing the SAM. Methods : Forty-one healthy subjects participated in this study. They were asked to rate the emotional valence and level of arousal using both the SAM and EVAS after being exposed to pictures of facial expressions for affective neurosciences-Korean version. The internal consistency of the EVAS and the correlation between EVAS and SAM were examined. Resuts : Internal consistencies of the valence using the EVAS were from 0.63 (surprise) to 0.82 (happiness) and those of the arousal were from 0.90 to 0.95. Correlation coefficients of the valence and arousal between the SAM and EVAS were from 0.61 (both surprise and disgust) to 0.84 (neutral) and from 0.82 (sadness) to 0.94 (fear), respectively. Conclusions : We developed a new manikin (the EVAS) for the Korean population modifying and standardizing the SAM. The EVAS demonstrated a good internal consistency and validity. As such, it can be used in the field of human emotion research.

The purpose of this study was to investigate whether there is a difference between the deokhu activities and the flow level of the deokhu group. We also tested whether there are any real differences in emotion before and after the deokhu activities. The study included 227 adults and results were as follows. First, the deokhu group had a high cost of investing and a high rate of one-day investments, particularly for one-week activities and years of duration compare to the non-deokhu group. Second, the higher the degree to which they perceived themselves as deokhu and the level of deokhu activities were higher in flow. and the group of deokhu was more absorbed than the non-deokhu group. Third, there has been no change in positive and negative feelings before and after deokhu activities in the non-deokhu group. For the deokhu group, the positive emotions of happiness, joy, tranquility, pleasure increased and negative emotions such as anger, anxiety, sadness, shame, and guilt were significantly reduced after deokhu activities. The perception of deokhu and deokhu activities have positive functions that increase the level of flow, relieve negative feelings and enhance positive emotions.

The This study aims to verify the causal relationship among physically disability persons participation in exercise, heart rate variance, and facial expression recognition. To achieve such research goal, this study targeted 139 physically disability persons and as for sampling, purposive sampling method was applied. After visiting a sporting stadium and club facilities that sporting events were held and explaining the purpose of the research in detail, only with those who agreed to participate in the research, their heart rate variance and facial emotion awareness were measured. With the results of measurement, mean value, standard deviation, correlation analysis, and structural equating model were analyzed, and the results are as follows. The quantity of exercise positively affected sympathetic activity and parasympathetic activity of autonomic nervous system. Exercise history of physically disability persons was found to have a positive influence on LF/HF, and it had a negative influence on parasympathetic activity. Sympathetic activity of physically disability persons turned out to have a positive effect on the recognition of the emotion, happiness, while the quantity of exercise had a negative influence on the recognition of the emotion, sadness. These findings were discussed and how those mechanisms that are relevant to the autonomic nervous system, facial expression recognition of physical disability persons.

This study aims to investigate how religious orientation of college students and the religious fundamentalism are related to their subjective well-being, and the interaction of religious orientations and the religious fundamentalism on their well-being. The participants were 374 college students who studies at an university located in Seoul, whose average of age were 22.54 (SD=4.79). The psychological tests used in this research included the following: I/E-R, the Religious Fundamentalism Scale, the Spiritual Well-Being Scale, Emotion Frequency Test, Satisfaction with Life Scale, Subjective Happiness Scale, Life Satisfaction Motivation Scale, and Life Satisfaction Expectancy Scale. Although religious students experienced more religious well-being than non-religious students, their subjective well-being were not higher than those of non-religious students. Results reveal that religious orientations were positively related to subjective well-being such as life satisfaction, subjective happiness, and positive emotions, as well as spiritual well-being. However, those covariance was approximately 4~6% only. Religious fundamentalism was also positively related to spiritual well-being and life satisfaction, it was negatively related to the motivation to live though. On the other hand, moderate effects of the religious fundamentalism on the relations of religious orientations to most of subjective well-being variables. Results of simple main effect analyses indicated that the students who were strongly oriented toward religion with higher religious fundamentalism showed significantly higher existential well-being, positive emotions, life satisfaction, subjective happiness, and especially their motivation and expectation for future life, whereas there were no significant differences in subjective well-being of students with lower religious fundamentalism by religious orientation. This finding suggests that some religiosity variables could affect human well-being with interactions

The skin-tone in portrait photography is one of the most sensitive parts that need retouching by a photographer. To investigate the emotional reactions related to users' preferences for the skin-tone variations in portrait photography, two experiments were conducted. The first experiment included JND(Just Noticeable Difference) test to determine the general distribution of preferences with many photographs that varied in phases up to an extreme one, as a result, preferences for the brightest skin-tone and the red or magenta one were found. Based on the first experiment, we reduced the number of samples by adjusting their brightness to the brightest phase constantly. To intensify the second experiment, we reduced the number of the other colored samples to only one and made samples for five phases from green to magenta, namely the most preferred skin-tone in the first experiment. In the second experiment, the common preference for a neutral skin-tone and the partial difference between the two gender groups were found. In conclusion, the users' preference for a particular skin-tone was positively affected by emotions such as 'happiness' or 'comfortable'. With this investigation, we compiled some statistically meaningful facts to confirm that the preferences of the users depend positively on controlling the skin-tone in portrait photography.

Hanok (a traditional Korean-style house) has recently become a popular attraction for tourists all over the world. Jeonju Hanok Village, for example, attracted about 10 million visitors for 2 consecutive years. Observing Hanok's popularity, many local governments drew up plans to improve tourism dynamics by strengthening the advantages of Hanok. Emotionally rich experience is required to offer a greater satisfying experience that meets the demands of tourists. However, very few studies yet have addressed how to measure those emotions felt by users while experiencing Hanok. As an attempt to improve this situation, 182 emotional words were collected from earlier studies and classified into 33 groups with the Delphi method. Among the emotional words in each of the 33 groups, those of overlapping concepts on the characteristics of Hanok were re-grouped, and extracted the most appropriate 68 words. Additionally, a survey was conducted with 325 people who had experienced Hanok to gather 30-most representative emotions for measuring emotions felt from Hanok. The factor analysis of the 30 representative emotions resulted in classified 6 factors based on common features of emotional words: senses of aesthetics, happiness, novelty, ownership, balance and relaxation. The 30 representative emotions and six emotion categories found out by this study can help measure how much people feel certain emotions while experiencing hanoks. Further study will explore the degree of emotions hanok users feel about objects of hanok, such as roof materials and shapes, and body shapes.
