가상환경시스템은 매우 현실감 있는 정보를 제공할 수 있다는 점에서 산업, 의료, 교육훈련 등에 널리 사용되고 있다. 그러나 아직 많은 가상환경 시스템에서 부정적 요인으로 멀미나 시각피로로 대표되는 cybersickness 증세를 수반하고 있어 그 사용과 확산에 제약이 되고 있다. 한편 cybersickness 의 한 현상으로 볼 수 있는 신체동요도 이에 대한 객관적 지표로서의 가능성이 연구되어지고 있다. 본 연구에서도 가상환경시스템을 피실험자들에게 체험하게 하고 체험 전후의 신체동요으 변화를 측정평가 하였다. 측정 결과 가상환경 체험 후 약간의 신체 동요의 경향이 나타났으나 통계적으로 유의할만한 정도의 차이는 보이지 못했다. 특히 본 연구에서 신체동요의 변인으로 가정했던 Motion의 유무와 Feedback 의 유무에 대한 영향 분석 결과에서도 좌우 방향에 대한 Motion 유무만 차이를 보였을 뿐이었다. 신체동요는 비교적 간단히 객관적으로 cybersickness의 일면을 평가할 수 있는 지표로 후속 연구가 계속 요청되고 있다.

본 연구에서는 형용사로 감성 반응을 평가하는 일반적인 감성공학 연구에서 감성공학 연구에서 감성 공간을 보다 쉽게 도식화하고 평가 방법을 단순화시키는 전략을 제시하고자 한다. 기존의 감성공학연구에서는 수집된 감성 어휘를 순차적으로 정리해 줄이는 방법을 취한 다음 최종 어휘 목록을 이용하여 평가 대상이 다소 복잡하여 표본의 수가 많은 경우 어휘 목록을 인위적으로 줄이지 않으면 신뢰로운 반응을 기대하기 어렵다. 본 연구에서는 보다 단순한 방법으로 감성 반응을 포괄적으로 얻을 수 있도록 하기 위하여 감성 형용사를 설명하는데 필요한 최소 차원을 설정하고 차원 평정치에 따라 필요한 어휘군의 목록만 사용하여 어휘를 평가할 수 있는 방법을 제안하고자 한다.

최근들어 제품개발에 앞서 제품으로 인해 유발되는 감성을 측정하기 위한 시도가 늘고 있다. 그러나 제품을 사용하면서 나타나는 행동의 변화는 많은 영향 요소를 포함하고 있어 이를 해석하기가 어렵다. 본 연구는 안정을 유도하는 Herb차를 개발하거나 치약과 같이 사용으로 인한 감성유발 효과를 보고싶어하는 요구에 따라 시행하였다. 우선 실험전 피검자의 불안 척도, 기본 check list에 따라 피검자를 선택하였다. 또한 객관적 감성 지표로는 Fz, Fp1, Cz, Oz에서 뇌파를 측정하였고 EOG를 시행하여 noise를 제거하였다. 자율신경계 반응으로 galvanic skin resistance(GSR), 피부온도, 심박수등을 동시에 측정하였다. 이들 제품 사용으로 인한 객관적 감성 변화의 대조군으로는 행동 시행전에 측정하였다. 제품 사용 후 10분 간격으로 30-60분까지 나타나는 변화를 측정하였으며, 이들 제품들은 안정 효과를 유도하고자 기획되었으므로 대조군으로 00 $\times$ 0의 복잡한 계산문제를 주어 stress로 인한 감성, 걷는 동작, 손 씻는 행위등을 나누어 측정하였다. 본 연구의 결과에 의하면, 제품 사용으로 인한 감성의 변화는 GSR에서 가장 잘 반영되었고 또한 계산 문제로 인한 자극에서도 역시 GSR의 변화가 가장 뚜렷하였다. Herb차인 경우 기호도에 따른 차이가 나타났음을 알 수 있었다.

Environmental conditions are known to impact human health and behavior, emotions such as pleasure, anxiety, and depression, and reduce stress. Interior design that elevates emotional comfort and satisfaction can help improve mental health and well-being. This study is a systematic review that analyzed previous empirical studies that explored the effect of interior design elements on the user's emotional response which is quantitatively evaluated by bio-signal and qualitatively evaluated through self-reported questionnaire surveys. This paper aims to derive the attributes of interior design and biometric indicators that affect the user's positive emotion through the synthesis of previous studies and to confirm the feasibility of measuring bio-signals as an objective evaluation tool for architectural design and as a quantitative research method. As a result of the review, the biometric data from EEG, fMRI, ECG, EMG, GSR, and eye-tracking were used to measure the participants' emotional responses, which were manifested as positive or negative depending on certain attributes of interior design such as the form, color, lighting, material and furniture. The attributes of interior design related to the positive emotional response were the curved shape, high ceiling, openness of space, and subdued tone colors. Standard lighting conditions and wooden spaces were related to stress reduction in terms of comfort and relaxation. The free arrangement of furniture was related to the user's positive emotions. On the other hand, consistent experimental protocols could not be found, and although the sample sizes of the studies were small, the studies have demonstrated the feasibility of the emotional response measurement by using the biometric data. Therefore this method can be a useful objective tool in the measurement of human-centric data in architectural design, and to develop the evidence-based design to induce positive emotions and minimize stress.

In a sense that achievement emotion is directly associated with achievement activity of students and its result, drastic changes in educational environment such as expansion of e-learning due to COVID-19 may have a large impact on the achievement emotion of students inevitably. However, studies on the foregoing still remain insufficient, and development of a questionnaire capable of making a quantitative measurement on the achievement emotion of students under the environment of e-learning may become the basis of relevant studies, so this study developed the e-learning Achievement Emotions Questionnaire-Korean Middle school Science(e-AEQ-KMS) and verified its validity. e-AEQ-KMS in this study was developed based on the Achievement Emotions Questionnaire-Korean Middle school Science (AEQ-KMS) and by reflecting characteristics of e-learning science class. With 226 questions in total, the questionnaire is composed to measure 9 kinds of achievement emotion such as enjoyment, hope, pride, relief, anger, anxiety, hopelessness, shame, and boredom under 3 academic situations of class situation, learning situation and testing situation. The result of this study has a great significance in the way that it set out a framework for making a comparative analysis quantitatively on the achievement emotion of Korean middle school students in science for e-learning classes.

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.

Objectives: The aim of this study is to investigate the core emotion assessment instrument based on the Chiljeong. Methods: We searched for a literature review of oriental medicine and established the operational definition. Based on the existing psychological scale measurement, we selected the items and analyzed the reliability through a two-step preliminary study. Results: 1) Through the analysis of reliability after the two-step preliminary study (first: 170 items, n=63, second: 152 items, n=42), we had excellent internal consistency (Cronbach's alpha > 0.70) as well as good test-retest reliability (>0.70). Thus, we demonstrated that this scale had reliability. 2) Analyzing the correlation of each emotion, we had a comparatively strong positive-correlation (>0.6), except for Hui, and found a particularly high correlation of Sa, U and Bi. Conclusions: We developed the final 141 items of the core emotion assessment instrument through the two-time preliminary study. In the future, the main study on the clinical and non clinical groups of various ages should be continued.

The purpose of this study was to determine the relationships between fatigue, stress resistance and emotion in middle aged women under the developmental crisis using a brain wave measurement which is a cranial physiological index. From March 2005 to June 2009, women aged between 35 and 65 (N=4402) who volunteered for a brain wave test at the KRIJUS( Korea Research Institute of Jungshin Science) were monitored the brain function quotient (tension degree, anti-stress quotient and emotional quotient). Correlation and time-series linear analysis revealed significantly the relationships between fatigue, stress resistance and emotion. Also, according to the emotional propensity, cheerful propensity was higher in the cheerful and depressed propensity, positive propensity was higher in the positive and negative propensity, during the whole test, cheerful and positive propensity was higher. Therefore, it is necessary to increase the quality of life by decreasing fatigue and stress level of the middle-aged women to maintain and increase their individual health and the better family relationship.

This study investigates the effects of justice dimensions on negative emotion, consumer satisfaction after service recovery, repurchase intention and word-of-mouth intention in a context of service recovery. Behavioral intentions(repurchase intention and word-of-mouth intention) are critical to the discount store sellers' survival and success. The research model is an extension of previous studies, especially considering more recent developments in the service recovery literature. A survey using 458 customers in China was conducted, confirmatory factor analysis was conducted to test the validity of the measurement model, and AMOS analysis approach was used to gain important insights into how customer retention in the discount store business can be ensured. The results suggest that all three dimensions of justice had negative effects on negative emotion, had positive effects on satisfaction after service recovery. Negative emotion had negative effects on recovery satisfaction. Recovery satisfaction had positive effects on repurchase intention and word-of-mouth intention. Finally, this study suggests the implications of these findings and offers directions for future research.
