Autonomic and EEG responses of 38 college students were studied during 60-sec long presentation of International Affective Picture System (IAPS )slides evoking, according to subjective reports, negative (disgust, sadness, surprise) and positive (happiness, exciting) emotional. states. Observed were significant heart rate (HR) deceleration, large skin conductance responses (SCR), moderate respiration frequency slowing, reduction of frontal (F 3, F 4 ) and occipital (O 1, O 2 ) fast alpha, and increases of theta, delta and beta relative spectral power values during the first 30 sec of exposure of IAPS pictures. Analysis carried out to differentiate emotion categories according to autonomic responses indicated that observed HR deceleration was larger in magnitude in surprise and sadness than in disgust, SCR amplitude higher in sadness than in disgust. EEC showed significant differences in theta (F 3, F 4 ) and delta (O 1) power increase in disgust vs. happiness, fast alpha (F 3, F 4 ) power was lower in surprise than in happiness, and slow beta power higher. in happiness than in disgust (0 1). Despite some differences. observed within discrete emotion conditions, overall responses pattern of monitored parameters exhibited similar profiles with few variations, most. obvious. in disgust state, which suggests that affective visual stimulation elicits stereotypical responses in a given passive viewing paradigm. However, the magnitude of physiological responses may vary to certain extent across discrete emotional states making it possible to differentiate among particular experimentally-induced emotional states, e.g., disgust vs. sadness by ANS responses or disgust vs. happiness by EEG measures.

As smartphone usage has increased recently, so has smartphone addiction. Many of the smartphone users, however, do not even recognize the risk of smartphone addiction. In this experiment, smartphone users have been categorized into two groups by smartphone addiction measure (S-measure) developed by 2011 National Information Society Agency (NIA): A high risk group and a normal group. The changes of brain waves have been observed when the subjects were watching emotional videos of anger, sadness, happiness, and fear. The results show that the values of FP1 and FP2 (frontal lobe) theta band of the high risk group have been measured to be high, which indicate anxiety disorder. Although happiness and fear videos showed no difference between these groups, sadness and anger videos showed significantly different results for these groups: the brain waves of the high risk group showed higher values than those of the normal group. Therefore, this experiment showed that the high risk group takes feelings of sadness and anger more sensitively than the normal group.

Frontal (F3, F4) EEG responses were analyzed and compared during exposure too slides of International Affective Picture System (IAPS) in the study on 42 students. EEG responses during 20 s of exposure to slides intended to elicit happiness (nurturant and erotic), sadness, disgust, surprise, fear or anger emotions were quite similar and were exhibited in theta increase, alpha-blocking and increased beta activity, and frontal asymmetry. However, particular emotions demonstrated variations of the EEG response profiles, enabling to differentiate some pairs of emotions. The profiles showed higher magnitudes of EEG responses in exciting (i.e., erotic happiness) emotion. The most different pairs were exciting -sadness (theta, alpha and alpha asymmetry), exciting-surprise (theta, alpha asymmetry), and exciting-fear (theta, F3 alpha, alpha asymmetry). Nurturant happiness yielded the least differentiation. Differences were found as well within negative emotions, e.g., anger-sadness were differentiated by theta asymmetry, while disgust-fear by beta asymmetry. Obtained results suggest that magnitudes of profiles of EEG variables differentiate emotions elicited by affective pictures.

The purpose of this study was to identify the effect of experience emotion (i.e., happy, proud, sad, fear) on the risk perception. This study also examined interaction effects of emotion regulation (i.e., reappraisal strategy, problem focused strategy) between experience emotion and risk perception. The study collected data from 168 flight crew members in Korean commercial airlines, using an online research in which an experiment of emotion manipulation and a survey were included. The results of the study found the positive effect of happiness emotion on the risk perception regarding cases 1(these cases have high possibility of negative result and low circumstance control) and the positive effect of sadness emotion on the risk perception regarding cases 2(these cases have low possibility of negative result and high circumstance control). This study also found the interaction effect of reappraisal emotion regulation strategy between the relationship of happiness and risk perception regarding cases 2. From these results, the study provided that theoretical and practical implication that happiness and sadness emotion contribute risk perception and reappraisal strategy has a moderating role in the relationship between happy emotion and risk perception. Finally, based on these results, the limitations of this study and future research were discussed.

삶의 치유는 무덤으로 통할까, 아니면 죽음이 삶을 치유할 수 있을까. 삶에 있어서의 치유는 삶의 공간의 감정 회로에 존재한다. 그러면 죽음에서의 치유는 어떤 공간에 존재할까. 일단은 죽음에서의 치유는 삶의 너머에 있다. 임제(林悌, 1549~1587)는 그가 사랑하는 황진이의 무덤에서 슬픔의 시조를 읊은 것으로 유명하다. 문학치료를 위해, 이번에는 임제가 황진이의 무덤에서 읊었다고 하는 시조 "청초 우거진 골"의 감정들을 코딩하려고 한다. 이 시조는 사랑과 죽음, 무덤과 슬픔이라는 고통같은 슬픔의 사랑을 노래한다. 즉 사랑과 아픔 혹은 사랑과 이별이라는 상반된 개념이 일으키는 인간의 감정이 어떻게 융합하는지에 관련된 것이다. 임제의 이 시조는 무덤과 사랑과 슬픔이라는 기표들을 융합하여 '인생의 무상함'을 코딩한다. 이 '인생의 무상함'이 이 시조의 문학치료 기능이다. '인생의 무상함'은 인체의 긴장을 풀어주는 치유의 역할을 한다. 이렇게 문학치료가 이루어지면 아무리 고통스러운 삶이라도 우리들은 여유를 가지게 된다. 이 시조에서 전달하는 '인생의 무상함'에 대한 슬픔이 삶 전체를 관조하며 관용하는 문학치료의 효과를 전달하기 때문이다. 앞으로 이러한 연구를 지속하여 새로운 삶에 대한 감정 코딩이 이루어지길 기대한다.

이 글은 한돌 이흥건의 타래를 서사와 미학의 측면에서 분석한다. 이 때 등장하는 분석 요소는 자연과 인간, 소외와 관심, 분단과 통일, 디아스포라와 겨레 등 이항 대립의 현상과 본질이다. 1970년대 후반부터 1990년대 초반까지의 타래는 군사 독재 때부터 발생한 산업화와 도시화, 난개발, 서구화, 입시 위주 교육, 빈부 차, 인간 소외, 분단 갈등의 사회 문제를 무저항과 불복종의 정신으로 맞서는 상실과 고통의 체험 서사를 노래하였다. 그리고 창작 의욕이 단절된 공백기를 자기 성찰과 노력으로 극복한 이후의 타래는 '자연의 울림과 자기의 참모습', '디아스포라 의식과 겨레의 얼'을 일체화하는 디아스포라 서사시의 느낌이 두드러진다. <터>에서 시작한 조국과 국토, 겨레에 대한 서사시는 <한뫼줄기>를 전환점으로 뿌리보다 길을 찾는 디아스포라 의식이 선명해진다. 한돌은 음악보다 서사의 원천에서 영감을 얻는다. 그의 타래는 '노랫말을 위해서 리듬이 곁들어지는 것'에 치중한다. 이 때문에 타래가 갖는 기호학적 특성은 내재적 의미(슬픔의 정서)가 오묘해도 외형적 음운이 단순한 것이 한계다. 공감과 더불어 감동까지 끌어내는 데는 내포적(의미론적)인 부분과 외연적(음운론적)인 부분의 조화가 필요하다. 슬픔의 정서를 더 많은 사람이 공유하려면 음운론적 요소를 강화할 필요가 있다. 슬픔에 대한 공감과 감동은 동일한 경험의 이야기보다 비슷한 정서의 분위기에 이끌리는 경우가 더 많다. 타래 속 슬픔의 미학은 유년 시절부터 겪은 상실과 고독, 가난의 맥락에서 표출된 원초적인 체험 서사에서 출발하지만, 긴 공백기를 거치면서 심화한 슬픔의 미학은 타인(실향민, 해외 입양자, 러시아 고려인, 일본군 위안부 피해자 등)의 디아스포라 경험까지 자기화하면서 궁극적인구원 서사를 지향한다. 이로써 타래는 잠재적으로 민족의 한계를 뛰어 넘을 가능성도 지니게 되었다. '이산되는 소리'로서의 타래는 다른 세계 음악과의 접점에서 깊은 슬픔의 호소력으로 유리한 국면을 맞을 수 있다. 반다문화주의가 아닌 상호문화주의의 지향으로 글로벌 디아스포라 담론을 형성할 수도 있다. 한돌의 타래는 디아스포라 음악으로서 지속적으로 공감의 영역을 찾고 인식의 지평을 넓혀나가는 것이 향후 과제요 목표다.

This paper describes a technique for human sensibility evaluation using EEGs of 4 emotions. The proposed method uses the linear predictor coefficients as EEG feature parameters and a neural network as sensibility pattern classifier. For subject independent system, multiple templates are stored and the most similar template can be selected. EEG signals corresponding to 4 emotions such as relaxation, joy, sadness and anger are collected from 5 armature performers. The states of relaxation and joy are considered as positive sensibility and those of sadness and anger as negative. The classification performance suing the proposed method is about 72.6%. This may be promising performance in the human sensibility evaluation.

In this paper, our study focuses on obtaining the differences of emotional speech in three different vocal tract sections. The vocal tract area was computed from the area function of the emotional speech. The total vocal tract was divided into 3 sections (vocal fold section, middle section and lip section) to acquire the differences in each vocal tract section of emotional speech. The experiment data include 6 emotional speeches from 3 males and 3 females. The 6 emotions consist of neutral, happiness, anger, sadness, fear and boredom. The measured difference is computed by the ratio through comparing each emotional speech with the normal speech. The experimental results present that there is not a remarkable difference at lip section, but the fear and sadness have a great change at the vocal fold part.

Depression has a relatively high lifetime prevalence rate in spite of a genetic influence on its etiology and a high mortality rate in untreated cases. This suggests the possibility that depression gives us evolutionary benefits which we do not exactly know yet. There have been several hypotheses which tell us what evolutionary advantages depression could give us. The psychic pain hypothesis considers sad or depressed mood as a negative reward just like physical pain which we have to avoid for our protection and survival. The social rank hypothesis holds that depressed mood is very similar to the emotional state of the defeated in social competition which prevents him from further protesting or fighting that might cause additional damage to him. The inclusive fitness hypothesis views suicide as a sacrifice phenomenon to contribute to inclusive fitness. These hypotheses gives us new insights into mood disorders and also some suggestions about the conditions in which depressed mood or suicidal behaviors increase and the ways to reduce them.
