This study was intended to investigate the effects of forest therapy programs using school forest on the emotional stability and positive thinking of university students. The subjects were divided into an experimental group and a controlled group, and the number of subjects in each group was 35 and 25, respectively. The forest therapy program was conducted once a week from 4 September to 12 December in 2018 for a total of 8 sessions, and each session lasted two hours (120 minutes). The subjects were examined in the emotional state and positive thinking before and after the forest therapy program. To determine the difference in emotional stability and positive thinking before and after the program, I conducted a paired t-test and analyzed the data with the SPSS 21.0 program. The results indicated that students who participated in the program showed a significant increase in the stabilize emotional state and positive thinking. This study shows that forest therapy programs using school forests have an effect on students' emotions and positive thinking. Thus, it is necessary to promote the forest therapy program as an alternative activity for the treatment and prevention of mental health of university students.

The present study investigated whether the emotional states reading ability through facial expression changes by age(3-, 5-year-old and university student groups), sex(male, female), facial expression's presenting areas(face, eyes) and the type of emotions(basic emotions, complex emotions). 32 types of emotional state's facial expressions which are linked relatively strong with the emotional vocabularies were used as stimuli. Stimuli were collected by taking photographs of professional actors facial expression performance. Each individuals were presented with stories which set off certain emotions, and then were asked to choose a facial expression that the principal character would have made for the occasion presented in stories. The result showed that the ability of facial expression reading improves as the age get higher. Also, they performed better with the condition of face than eyes, and basic emotions than complex emotions. While female doesn't show any performance difference with the presenting areas, male shows better performance in case of facial condition compared with eye condition. The results demonstrate that age, facial expression's presenting areas and the type of emotions effect on estimation of other people's emotion through facial expressions.

In this study, the tasks of thermal equilibrium and heat insulation concept were divided into scientific and everyday contexts to analyzed the level of familiarity, feeling of knowing, state curiosity, and state anxiety that students feel in task contexts and their relationship. The subjects of this study were One hundred nine students in sixth grade of elementary schools located in metropolitan cities. The results of this study were as follows. First, there was no difference in the level of feeling of knowing, state curiosity, and state anxiety in the task of scientific and everyday contexts. In the case of familiarity, there was no consistent tendency in the concept of thermal equilibrium and heat insulation. And the group who recognized the task context familiarly had higher feeling of knowing and lower state anxiety than the group who recognized the task context unfamiliarly. Second, familiarity and feeling of knowing showed high positive correlation, state anxiety and familiarity showed negative correlation, and state anxiety and feeling of knowing had also negative correlation. In addition, familiarity had a negative effect on state anxiety, and FOK had a positive effect on state curiosity and a negative effect on state anxiety. There was no significant moderating effect of the task context. Third, in case of state curiosity, the group perceived the knowledge gap was very small had the highest state curiosity, and the group perceived the knowledge gap was very large had the lowest state curiosity. In case of state anxiety, the less the knowledge gap was perceived, the lower the anxiety was triggered. This study broadens our understanding of the learning process and provides implications for effective instruction strategies for students' cognitive and emotional states.

For a friendly interaction between human and robot, emotional interchange has recently been more important. So many researchers who are investigating the emotion generation model tried to naturalize the robot's emotional state and to improve the usability of the model for the designer of the robot. And also the various emotion generation of the robot is needed to increase the believability of the robot. So in this paper we used the hybrid emotion generation architecture, and defined the generalized context input of emotion generation model for the designer to easily implement it to the robot. And we developed the personality and loyalty model based on the psychology for various emotion generation. Robot's personality is implemented with the emotional stability from Big-Five, and loyalty is made of familiarity generation, expression, and learning procedure which are based on the human-human social relationship such as balance theory and social exchange theory. We verify this emotion generation model by implementing it to the 'user calling and scheduling' scenario.

Purpose: The purpose of this study was to investigate life stress, social support, and antepartum depression among Southeast Asian immigrant women married to Korean men. Methods: Ninety-three subjects were recruited from local women's clinics and multicultural family support centers in D City. The instruments used were the life stress scale, social support scale, and K-EPDS. All the instruments were translated into their corresponding mother languages (Vietnamese, Cambodian, and Philippine) and notarized. Results: The item mean scores of life stress and social support were 2.65 and 3.17, respectively, on a 5-point Likert scale. The mean score of antepartum depression was 10.16, indicating that they were generally in a depressive state. A positive correlation was observed between life stress and antepartum depression (r=.59, p<.001). Social support was negatively correlated with life stress (r=-.42, p<.001) and antepartum depression (r=-.39, p<.001). The best predictors for antepartum depression were life stress, marital satisfaction, and emotional support, and they explained 43% of the variance. Conclusion: Antepartum depression in Southeast Asian immigrant brides was significantly associated with life stress as well as lack of emotional support. Emotional support may reduce their life stress and antepartum depression.

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.

In this paper, human sensibility is measured on multi-modal environment and a sensitivity lighting system is implemented according to driven emotional indexes. We use LED lighting because it supports ecological circumstance, high efficiency, and long lifetime. In particular, the LED lighting provides various color schemes even in single lighting bulb. To cognize the human sensibility, we use the image information and the arousal state information, which are composed of multi-modal basis and calculates emotional indexes. In experiments, as the LED lighting color vision varies according to users' emotional index, we show that it provides human friendly lighting system compared to the existing systems.

There has been a considerable number of studies on aggressive behaviors and violences, but it is hard to find one that gives us clear and satisfactory answers with transparent conclusions. Juvenile aggressiveness seems to be caused by unsatisfied desire in the problematic situations and emotional instability. The aim of this study is to find out how emotional instability - especially mathematics anxiety - is correlated with aggressiveness and how aggressiveness affects mathematics proficiency, and thus to help students improve their academic proficiency by finding out appropriate measures to take in case of aggressive behaviors of students. Main tasks of this study are as follows : 1. To find out any correlation between aggressiveness of the experimental students and their mathematics proficiency. 2. Is there any correlation between aggressiveness and mathematics anxiety\ulcorner 3. Is there any correlation between aggressiveness and academic proficiency\ulcorner The conclusion of this study is as follows : 1. There are some negative correlations between the degree of mathematics anxiety and mathematics proficiency. This is mainly because negative emotional state developed from one's uneasiness for fear of failure disturbs one's learning process and thus weakens the will for achieving the task. 2. While aggressiveness doesn't show any significant correlations with academic proficiency, it does have some with mathematics anxiety.

Cell phone users frequently send and receive text messages with emoticons in their everyday lives, but emoticon and its emotional effect on message in mobile context has not been focused on. The purpose of this study is to investigate the emotional effect of emoticons on interpretation of text message considering valent texts and emoticons. Study 1 showed the effect of valent emoticons on neutral message, and also revealed that existence of emoticon, regardless of its valence, decreases rigidness and increases familiarity of message. In Study 2 that used positive and negative text messages, we found that emoticon still affects assessing sender's mood state and emotion. Result of interaction between valences of text and emoticon showed that participants in condition of incongruent pairs felt more sarcasm.
