  • Korean constitutional type(Sasang Chejil) was considered with anxiety level and personality type in order variability frequently encountered in EEG research. Sasang Chejil type seems a very important factor to be controled to minimize the variabilty since Sasang Cheji subgroups showed distinct differences in EEG relative power ao more recording sites and frequency bands than the subgroups of anxiety level and personality type, well-reconized variability-contribution factors. It is likely that Tae-Eum Chejil type is predispositioned to be more relaxed and feel happier and less unhappy than So-Yang type since the former showed greater alpha relative powers and left-hemisphere activations at both of the resting and emotional states.

  • According to the literatural study on the causes of Infertility in women, the results were as follows. 1. The causes of Infertility in women were arranged scholarly thoery during to Jin-Yuan era (金 元 時代) from Huang-Di-Nei-Jing(黃帝內經), and literatures after Ming-Qing era(明 淸 時代) divided and added one's own thoery since they choose preceding thoery. 2. In the Modern Medicine, the causes of Infertility in women are divided the product obstruction of Oocyte, the union obstruction of sperm and oocyte by abnormality of vagina, cervix, corpus, fallopian tubes, pelvic, and peritoneum, Endocrine factor, Immunologic factor, and Emotion factor. 3. In the Oriental Medicine, the causes of Infertility in women are attached importance to functional side as 'asthenia-cool of uterus'(子宮虛寒), 'deficiency of vital energy and blood'(氣血虛), 'deficiency of yin'(陰虛), 'impairement of seven emotion'(七情傷), 'disease of extra mierdians'(寄經病), and so forth; while on the other in the Modern Medicine, the causes of Infertility in women are attached importance to organic side as abnormality of uterus and ovary. 4. In the successive literatures, 'asthenia-cool of uterus'(子宮虛寒) occupied most frequency in the causes of Infertility in women and in the next obesity(體肥), 'deficiency of vital energy and blood'(氣血虛), menstrual irregularity(月經不調), deficiency of yin'(陰虛), 'impairement of seven emotion'(七情傷), emaciation(體瘦), 'disease of extra mierdians'(寄經病), and so forth occupied much frequency. 5. In the bodily form, obesity(體肥) and emaciation(體瘦) occupied comparatively more frequency.

  • The paper is addressed to the topic of physiological response-specificity in disgust induced by visual stimulation. The purpose of this study was to evaluate reproducibility of physiological reactivity pattern during disgust elicited by the International Affective Pictures System (IAPS) in 2 experiments. Twenty-nine subjects participated in the first experiment with 3 visual stimulation sessions with disgust-eliciting slides (3 slides in each 1 min long session). In the second experiment disgust-eliciting slides from the IAPS were presented to 42 subjects in 2 sessions (one slide for 1 min). Spectral power of frontal EEG, skin conductance (SCL, SCR and NS.SCR), heart rate(HR), heart period variability(HPV) and respiration rate were recorded. Visual stimulation evoked 1:.n deceleration, higher power of high frequency component of HPV, increased SCL and NS.SCR frequency, frontal slow alpha blocking and moderate increase in fast beta power in most of the sessions in both experiments. However in the second experiment the EEG pattern associated with disgust showed inconsistent shifts in fast alpha and slow beta bands, but was marked by higher power of theta activity. Our data in both experiments emphasizes presence of disgust-specific profiles of autonomic and at the less extent EEG responses in visual stimulation context. Discussed are potential behavioral mechanisms leading to observed physiological manifestations in disgust elicited by visual stimulation. The results support the consideration that disgust is an withdrawal type negative valence emotion associated with relatively low autonomic arousal (low HR, low amplitude SCRs with relatively high NS.SCR frequency) and moderate EEG activation signs. Obtained data showed more consistent reproducibility of disgust-specific autonomic rather than EEG response patterns during visual stimulation design.

  • 외부환경의 변화에 의한 감성의 상태를 특정 자극을 인식한 후 나타나는 생리신호의 정량적인 분석기법을 개발함으로써 감성과 생리신호간의 상관관계를 찾고자 하는 연구가 절실히 요구되고 있다. 본 연구에서의 자극은 모터를 이용하는 자극기를 제작하여 부드러운 천과 거친사포를 피검자의 왼손바닥에 제시하였다. 그리고, 피검자에게 피부자극을 제시할 때 피검자가 자극의 특성을 인식하는 과정에서 발생되는 뇌파를 검출, 분석하고자 하였다. 분석방법으로서는 nonstationary한 신호분석에 유용한 특성을 가지고 있는 wavelet변환을 이용한 시간-주파수 EEG 신호의 특정범위에서의 시간-주파수 에너지성분의 변화를 관찰하였다. 그 결과 무자극시의 뇌파와 자극시으 뇌파를 비교하였을 때 부드러운 자극을 제시한 경우에는 낮은 주파수 대역에서 에너지가 우세함을 보였으며, 거친 자극에 대해서는 20-30Hz대역에서의 우세한 에너지 분포가 관찰되었다.

  • 본 논문에서는 감정에 따라 변화하는 혈류량을 측정하는 PPG 센서를 사용하여 감정을 인식하는 방법을 제안한다. 기존의 PPG 신호로부터 전력스펙트럼밀도(PSD; Power Spectrum Density)를 통해 주파수 영역에서 긍정적인 감정과 부정적인 감정을 판단하는 방법을 활용한다. 제임스 러셀의 이차원 원형 모델에 기반을 두어 감정을 기쁨, 슬픔, 짜증, 평온으로 분류하여 주파수 영역에 따른 에너지의 크기와의 연관성을 살펴본다. 본 연구는 웨어러블 디바이스에서 사용되는 동일한 PPG 센서를 사용하여 상위 네 종류의 감정을 영상 실험을 통해 주파수 영역에서 측정하였다는 것에 의의가 있다. 설문 조사를 통해 정확도와 개인에 따른 몰입 정도와 감정 변화 및 영상에 대한 바이오피드백을 수집하였다. 제안하는 방법은 앞으로 PPG 센서를 사용하는 상용화된 웨어러블 디바이스와 기존에 사용하는 스마트폰의 상황정보와 융합되어 모바일 어플리케이션 예측 서비스 등 다양한 개발이 될 것으로 기대된다.

  • The purpose of this study is to investigate the causal relationship between the variables related to media sports violence viewing experience, negative emotion, aggression and violent imitation behavior of middle school students and high school students. The subjects of 240 middle school students and 240 high school students were surveyed for 2 months. Among the collected data, 64 samples judged to have low reliability were excluded from the analysis, and the final 416 data were used. The questionnaire used in this study consisted of four potential variables including experience of watching media sports violence, negative emotion, aggression, and violent imitation behavior. Among the sub-variables of experience of watching media sports violence, exogenous potential variables except frequency, period and time and questions that are endogenous potential variables were composed of a questionnaire of 5-point Likert scale. results of this study were analyzed using the AMOS statistical program, which was used to identify the causal relationship between watching media sports violence and negative emotion, aggression, and violent imitation behavior. There was no significant difference in violent imitation behavior according to school grade. The causal models for media sports violence viewing experience, negative emotions, aggression and violent imitation behavior were found to be appropriate. It was found that there was a significant causal relationship between the viewing experience of sports violence and the violent imitation behavior. Therefore, in order to reduce the imitation behavior of adolescents, it is necessary to be more careful about the production and viewing of sports violence programs at the institutions and homes that produce media.

  • The purpose of this study is to explore the general trends and the correlations of parent-child conflicts, copings, and psychological well-being of single mothers and their children, and to analyze the variables explaining relationships between single mothers and their children. The subjects were 196 dyads of single mothers and their children who reside in Gwangju city and Jeonnam area. The data were analyzed with frequency, t-Test, Pearsons' r, and multiple regression by SPSS. The major findings are as follows: 1. Scores of single mothers and their children had conflicts and emotion-focused copings lower than median. Another scores of single mothers and their children had significantly higher problem solving focused copings and emotion-focused copings than their children except life satisfaction; 2. Conflicts, copings, life satisfaction, and depression of a single mother were positively related to those of children; 3. Life satisfaction of single mothers depends on the reason for spouse-loss, their own education background, and problem solving-focused copings. Also, that of children depends on problem solving-focused copings, mother-child conflicts, and the mothers' education. Depression of single mothers is dependent upon mother-child conflicts, emotion-focused copings, and mothers' education. Also, that of children is upon mother-child conflicts, emotion-focused copings, mothers' education, and problem solving-focused copings.

  • Speech can actively elicit feelings and attitudes by using words. It is important for researchers to identify the emotional content contained in speech signals as well as the sort of emotion that resulted from the speech that was made. In this study, we studied the emotion recognition system using a database in Arabic, especially in the Saudi dialect, the database is from a YouTube channel called Telfaz11, The four emotions that were examined were anger, happiness, sadness, and neutral. In our experiments, we extracted features from audio signals, such as Mel Frequency Cepstral Coefficient (MFCC) and Zero-Crossing Rate (ZCR), then we classified emotions using many classification algorithms such as machine learning algorithms (Support Vector Machine (SVM) and K-Nearest Neighbor (KNN)) and deep learning algorithms such as (Convolution Neural Network (CNN) and Long Short-Term Memory (LSTM)). Our Experiments showed that the MFCC feature extraction method and CNN model obtained the best accuracy result with 95%, proving the effectiveness of this classification system in recognizing Arabic spoken emotions.
