This study proposed a Long-Short Term Memory network to consider changes in emotion over time, and applied an attention mechanism to give weights to the emotion states that appear at specific moments. We used 32 channel EEG data from DEAP database. A 2-level classification (Low and High) experiment and a 3-level classification experiment (Low, Middle, and High) were performed on Valence and Arousal emotion model. As a result, accuracy of the 2-level classification experiment was 90.1% for Valence and 88.1% for Arousal. The accuracy of 3-level classification was 83.5% for Valence and 82.5% for Arousal.

The purpose of this study was to show that yoga psychology aims to actualize the positive potentials in the depth of human mind with the perspective of body-emotion-mind-spirit integration. This approach is described in the context of modern positive psychology. For this purpose, the Self-realization of yoga psychology is discussed, which is to develop one's higher self as a center of psyche apart from one's psychological growth or maturation. An individual can experience positive emotions such as pleasure, joy, happiness and ecstasy through the typical yoga technique of concentration. Happiness is one of the main issues of positive psychology, but yoga psychology called it "ānanda" and divided it further into seven types. The positive emotions of positive psychology seem to be equivalent to positive states of mind in yoga psychology. But yoga regards calmness, tranquility, nonattachment and transcendence as the most valuable virtues for the full actualization of human potentials. From the perspective of yoga psychology, the tranquil state of mind is the wonderful fruit of long and arduous yoga practices. It is the calm and neutral state of mind which is free from all the turmoils of everyday life. Tranquility is beyond the scope of modern positive psychology's issues, but it offers some precious insights to them.

This study was performed to test the socioemotional selectivity theory (SST) with Korean adults. According to SST, perceiving their life as limited, people are motivated to enhance their mood by regulating their mood in such a way to maximize the positive emotions and weaken the negative ones. Being founded on the dialectical constructs which assume the positive and negative sides of emotional experience coexist, Korean adults were supposed to be less motivated to maximize positive emotions and weaken negative emotions. Thus the elderly koreans might regulate emotions not in the direction of maximizing the positive emotions and weakening the negative ones, but in the direction of not being highly aroused. 166 youth, middle-aged, and elderly were asked to rate the frequencies of 31 positive and negative emotions they had experienced during the last month. In addition, they were asked to judge whether they weaken / adapt / maximize their emotions after experiencing positive and negative events. The elderly experienced less positive emotions as well as negative emotions than youth. Youth experienced emotions of high arousal more often than those of low arousal, but the elderly experienced emotions of high arousal less often. The responses of weakening their negative emotions and their positive emotions were largest in the elderly group. On the other hand, the response of maximizing their positive emotions were largest in the youth group. These results show that the elderly maintains emotional stability by weakening both positive and negative emotions of high arousal.

This pilot study involved a single session of song-based music therapy to relieve the anxiety of intensive care unit (ICU) caregivers. Six caregivers of ICU patients participated in the intervention session individually. During the initial stage of the intervention, the participants' current emotional states were identified. Then they listened to familiar songs and playing a tone chime, which was intended to help them relax their body and reduce their psychological resistance. During singing experiences as an essential part of the intervention, the participants discussed the lyrics of songs in an attempt to find the meaning related to them. Also, they sang the songs with a live accompaniment in which their emotional states were reflected with changes in musical elements (e.g., tempo, dynamics, rhythm, or chords). In the final stage, they identified personal application to their everyday lives. To analyze the results, the State-Trait Anxiety Inventory (STAI) and a visual analog scale on emotional states were completed by participants before and after the session, and participants' verbal responses during the session were also recorded. According to the results, STAI anxiety scores significantly declined following the session. Also, they showed significant increases in positive emotions and significant decreases in negative emotions. This suggests that short-term music therapy can be an effective intervention for relieving the psychological distress of ICU caregivers.

This study was conducted by applying Selby and Joiner (2009)'s Emotional Cascade Model to the phenomenon of non-suicidal self-injury of adolescents, focusing on the school counselor's counseling experience. To this end, a focus group interview(FGI) was conducted with 56 counselors who had experience in counseling self-injured adolescents, and this study applied Braun and Clake's thematic analysis(2012). As a result, 8 categories and 16 subtopics were derived: 'negative emotional experience', 'maladaptive cognitive emotional dysregulation strategy', 'experience of emotional cascade', 'temporary relief of psychological pain', 'aggravation of the emotional cascade state', 'emotional pain from nonsuicidal self-injury', 'vicious cycle of nonsuicidal self-injury' and 'difficulty in controlling behavior that co-occurs with nonsuicidal self-injury'. These results are significant in expanding the understanding regarding the non-suicidal self-injury of adolescents through the perspective of school counselors who are in a position to consider the various systems surrounding adolescents in an integrated manner. Based on the research results, implications, limitations and future research were discussed.

Human has various types of emotions which affect speculation, judgement, activity, and the like at the moment. Specifically, walking is also affected by emotions, because one's emotion status can be easily inferred by his or her walking style. The present research on biped walking with humanoid robots is mainly focused on stable walking irrespective of ground condition. For effective human-robot interaction, however, walking pattern needs to be changed depending on the emotion status of the robot. This paper provides analysis and comparison of gait experiment data for the men and women in four representative emotion states, i.e., joy, sorrow, ease, and anger, which was acquired by a gait analysis system. The data and analysis results provided in this paper will be referenced to emotional biped walking of a humanoid robot.

The purpose of this study is to investigate the effects of clinical nurse's emotional intelligence (EI) and core self-evaluation (CSE) on career commitment. Subjects were 462 clinical nurses at two general hospitals in Seoul, and survey was conducted from May to July, 2017. Data were analyzed by t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression analysis. The results showed that career commitment was correlated with EI or CSE (r=.28, p<.001; r=.34, p<.001). EI was correlated with CSE (r=.44, p<.001). CSE, spouse status, EI, position, subjective health status, and working department were identified as the factors affecting the clinical nurse's career commitment ($R^2=.21$). To improve career commitment, it is necessary to assess clinical nurse's EI and CSE according to subjective health status, and to be considered marriage, position, and working department in developing a career convergence program.

Recently in HCI research, emotion recognition is one of the core processes to implement emotional intelligence. There are many studies using bio signals in order to recognize human emotions, but it has been done merely for the basic emotions and very few exists for the other emotions. The purpose of present study is to confirm the difference of autonomic nervous system (ANS) response in three emotions (boredom, pain, and surprise). There were totally 217 of participants (male 96, female 121), we presented audio-visual stimulus to induce boredom and surprise, and pressure by using the sphygmomanometer for pain. During presented emotional stimuli, we measured electrodermal activity (EDA), skin temperature (SKT), electrocardiac activity (ECG) and photoplethysmography (PPG), besides; we required them to classify their present emotion and its intensity according to the emotion assessment scale. As the results of emotional stimulus evaluation, emotional stimulus which we used was shown to mean 92.5% of relevance and 5.43 of efficiency; this inferred that each emotional stimulus caused its own emotion quite effectively. When we analyzed the results of the ANS response which had been measured, we ascertained the significant difference between the baseline and emotional state on skin conductance response, SKT, heart rate, low frequency and blood volume pulse amplitude. In addition, the ANS response caused by each emotion had significant differences among the emotions. These results can probably be able to use to extend the emotion theory and develop the algorithm in recognition of three kinds of emotions (boredom, surprise, and pain) by response measurement indicators and be used to make applications for differentiating various human emotions in computer system.

The study is to examine the psychophysiological responses evoked by negative emotions(fear and disgust) in children. 47 children(11-13 years old, 23 boys) participated in the study. While the children were experiencing fear or disgust emotion induced by audio-visual film clips, ECG, EDA, PPG and SKT are measured. Emotion assessment scale was used to confirm that emotions elicited by the film clips were significantly noticeable, which was measured self-report. The results turned out to be 100% and 89.4% of appropriate for fear and disgust emotions, respectively. Emotional intensity the children had experienced was rated as 4.05, 4.07 on 1-5 scale based on effectiveness of measurement of fear and disgust emotion. ANS reponses by fear and disgust were significantly between the resting state and emotional state induced. The result obtained from the fear emotion showed significant increases in SCL, NSCR, HR, RSA, RESP and HF. There was a significant difference in SCL and NSCR between the two emotions.

Purpose: The purpose of this research was to examine the effects of an exercise program on the physical, physiological, and emotional status of the aged. Method: This research adopted a nonequivalent control group pretest-posttest design. The subjects were 46 elders aged over 60 who were selected from those registered at three local health centers in G City, and 27 of them were assigned to the experimental group and 19 to the control group. The independent variable was the exercise program, and the dependent variables were physical status, physiological status, and emotional status. The exercise program was Performed for 60 minutes per time, 3 times a week and for 6 weeks. Data were collected from October to November, 2005. Result: Compared to the control group, the experimental group showed significant improvements in right lower extremity strength (F=46.119, p=.000), left lower extremity strength (F=53.265, p=.000) and waist flexibility (t=3.183, p=.003) as physical status, and in depression (t=-3.703, p=.001), perceived health status (t=4.821, p=.000), and self efficacy (t=3.866, p=.000) as emotional status. Conclusion: The results showed that the exercise program was effective in promoting the physical status, physiological status, and emotional status of the aged. Therefore, it is recommended to apply the program as a nursing intervention in clinical practice and education in communities.
