Purpose: This study aims to explore the relationship between exclusion experiences and tactile sensations in online contexts, moving beyond existing frameworks of social exclusion research. Social exclusion induces psychological and physiological pain similar to physical pain, which can lead to various behavioral responses aimed at overcoming these distressing experiences. This study focuses on the potential of touch to mitigate psychological and physiological pain. Individuals who experience social exclusion feel emotional distress, leading to an increased desire for physical contact, which is expected to influence their responses to positive tactile products. Data and methodology: To validate this, the study examines how individuals who have experienced social exclusion respond to tactile products, such as sweaters, in online environments. Results: The results indicate that participants in the exclusion condition had a higher purchase intention for tactile products compared to those in the control condition, confirming the psychological mechanism of the desire to touch these products. Conclusions: This research is the first to analyze the relationship between social exclusion and tactile products, contributing to the expansion of the field of social exclusion studies. Additionally, it provides practical implications for marketers regarding the exposure of products targeting individuals experiencing social isolation and emotional loneliness.

Pain is a complex symptom consisting of a sensation underlying potenial disease and associated emotional state. Acute pain is a reflex biological response to injury, in contrast, chronic pain consists of pain of a mininum of 6 months duration and associates with physical, emotional past experience, economic resources of the patient, family and society. Moreover, chronic pain is characterized by physiological affective and behavioral responses that are quite different than those of acute pain. The different type of stimuli exciting pain receptor are mechanical, thermal and chemical stimli and chronic pain are concerned with three of all stimli. The major three components of pain central(Analgesia) system in the brain and spinal cord are 'periaqueductal gray area of the mesencephalon', 'the raphe magnus nucleus' and 'pain inhibitory complex located in the dorsal horns of the spinal cord'. But unfortunately, the central biochemical mechanisms of chronic pain are not clearly defined. To proper management of chronic pain, comprehensive urderstanding as a psychosomatic aspect and multidisciplinary therapeuti-team approach must be emphasized.

Immigration of Koreans to the United States has increased since the 1960's. Adjusting to life in the United States produces a great deal of stress for immigrants. Despite better economic opportunites, many see the U.S. culture as threatening to their family and cultural values. Differences in culture, language, expectations and social behavior can lead to misunderstandings between health care providers and clients. These misunderstanding can leaf to frustration on the part of each. The ultimate result of this is that often Korean-immigrants do not get their health care needs met and stress response symptoms can lead to disease if there is no appropriate care. To determine the health care needs and concerns of Korean-Americans, a health needs assessment is needed. Appropriate and adequate information about the health care needs of these individuals is important as it relates to American policy changes allowing greater numbers of immigrants to enter the U.S. The purpose of this prospective study was to describe Korean-American stress response. This study focused on the primary presenting problems for which subjects reported having sought care. These included a variety of stress-related symptoms, including peripheral manifestations, cardiopulmonary symptoms, central-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, depression, anxiety, emotional irritability and cognitive disorganization. Of the 300 subjects who entered the study, 80% (N＝223) completed the questionnaire in full. Demographically, the percentage of females and males was 50% each and they ranged in age from 20 to 69 years. Ninety percent of the subjects were highly educated, 25% owners of business, 25% white collar professionals, 15% employed in sales or as skilled /unskilled labor, 30% had no occupation : and 5% were housewives or students. The SOS inventory is designed to quantify self-perception of behavioral, cognitive, and physiological components of the stress response. It consisted of 94 items divided into 10 subscales. The result of this study are as follows : The total mean 505 of all subjects (N＝223 was .8129 ; the mean 505 for male(N＝114) was .7665 and for females, (N＝108) .8594. The level of symptoms for central-neurologic and muscle tension was higher for than for males. The highest stress response of all subjects was emotional irritability symptoms(1.0644) : the lowest stress response of all subjects was peripheral manifestation symptoms.

The recognition of human emotional state is one of the most important components for efficient human-human and human- computer interaction. In this paper, four emotions such as fear, disgust, joy, and neutral was a main problem of classifying emotion recognition and an approach of visual-stimuli for eliciting emotion based on physiological signals of skin conductance (SC), skin temperature (SKT), and blood volume pulse (BVP) was used to design the experiment. In order to reach the goal of solving this problem, half-against-half (HAH) multi-class support vector machine (SVM) with Gaussian radial basis function (RBF) kernel was proposed showing the effective techniques to improve the accuracy rate of emotion classification. The experimental results proved that the proposed was an efficient method for solving the emotion recognition problems with the accuracy rate of 90% of neutral, 86.67% of joy, 85% of disgust, and 80% of fear.

Purpose: This correlation study was designed to examine the relationships among reported violence experience, hardiness, and job satisfaction of nurses in an emergency department and to identify the factors that predict their job satisfaction. Methods: The study was conducted using a convenience sample of one hundred and fifteen nurses from nine hospitals. Data were collected using structured questionnaires including Assault Response Questionnaire (Jung, 2008), Dispositional Resilience Scale-15 (Bartone, 1995) and job satisfaction Questionnaire (Yun, 2004). Data were analyzed by using descriptive statistics, Pearson correlation coefficients, and multiple regression. Results: Hardiness and job satisfaction were statistically significant positive correlation (r=.44, p<.001). Further, there was a negative correlation between response to violence experiences and job satisfaction (r=-.33, p<.001) and between hardiness and response to violence experiences (r=-.41, p<.001). Emotional response and physiological responses of violence experience and hardiness were significant predictors of job satisfaction, and explained 29.6% of the total variance. Conclusion: Previous experiences with violence were an important factor which contribute to lower job satisfaction as reported by emergency department nurses. However it was also noted that hardiness was an important factor that could be used to improve job satisfaction of emergency department nurses.

자동화된 운항 시스템 도입으로 항공안전은 크게 개선되었지만, 운항을 직접 담당하는 항공기 조종사에게는 새로운 도전이 생겼다. 항공운항 관점에서의 조종사의 스트레스를 Startle과 Surprise구분할 수 있다. Startle을 총소리 같이 갑작스럽거나 위협적인 자극에 대한 짧고 강한 생리적인 반응이며, Surprise는 자신의 예상을 빗나가는 예기치 못한 사건에 대한 인지-감정적 반응이다. Martin 등이 실시한 Startle 효과 실험(2012년)에서 조종사는 Startle 상태에서 반응 지연과 심박 수 증가 등 생리적인 반응을 확인하였고, Rahim의 Startle/Surprise 실험(2020년)에서 사전 계획된 비상조치훈련은 조종사의 호흡수와 맥박수의 변화가 없으나, 비계획된 상황과 항공기가 복잡할수록 호흡 수와 심박 수가 증가되었다는 사실을 확인하였다. 이 실험 결과를 바탕으로 국내 조종사 훈련에서도 기술적 능력을 전달에만 집중하는 것이 아닌 비기술적 능력에 대한 고려가 필요하며, 법령에 의한 기계획된 단순 반복적인 훈련 항목보다는 항공사의 상황을 고려한 비정형화된 다양한 비상조치 훈련의 도입이 필요하다고 하겠다.

Purpose: The purpose of this study was to identify the effects of family visits upon the stress response of patients and their families, Methods: This study was the interrupted time series design, The subjects consisted of 197 patients and 197 family members in the cardiac intensive care unit of S Hospital in Bucheon. Physiological stress responses such as blood pressure, heart rates, respiration rates, and oxygen saturation were measured using HP monitors. VAS was used to measure the emotional stress. Collected data was analyzed using repeated measure ANOVA, t-test by SPSS 17.0 statistical program. Results: The family visits did not change patients' blood pressure, pulse rate, respiration rate and oxygen saturation, However the anxiety level of patients and their family members were decreased significantly during family visits. Furthermore, 30-minute family visit reduced more effectively patient's anxiety than 15-minute family visit. Conclusion: Family visits need to be used as a means of nursing intervention to ease the emotional stress of patients and their families. In addition, increasing of visiting time should be considered.

We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are no quantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by visual stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. Seven university students were participated in this study. The experiment was devised with eleven experimental conditions, which are control and ten different types of visual stimulation based on IAPS (International Affective Picture Systems). Wavelet transformation was employed to analyze the EEG signals. Most positive and negative emotional response were compared in pairs. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with positive and negative stimulus were found. This study could be extended to establish an algorithm which distinguishes psychophysiological states of the subjects exposed to the visual stimulation.
