Decades of psychological research have shown that emotion brings users various kinds of physical and psychological advantages and disadvantages. Moreover, this also impacts human decision-making. However, in spite of the weight of emotion, combined with HCI, relevant research is still insufficient. We hypothesized that the user's temporal emotion could influence the product evaluation, especially in terms of product usability. Two studies were carried out to investigate the effect of induced priming on user evaluations. In exp1, we manipulated participants' temporal emotions using positive and negative images from IAPS. In our results, we saw image priming had a statistically significant effect, with the positive condition group giving the product high ratings for usability. In exp2, emotional image manipulation was conducted with valence and arousal. As a result, we found that the variables of valence and arousal had some interaction effects. These studies have demonstrated that temporally induced emotion could affect users' emotion in different ways, in addition to influencing product evaluations.

This study analyzed users' emotional responses to VI character design through YouTube comments. The researchers applied text-mining to analyze 116,375 comments, focusing on terms related to character design and characteristics of VI. Using the BERT model in sentiment analysis, we classified comments into extremely negative, negative, neutral, positive, or extremely positive sentiments. Next, we conducted a co-occurrence frequency analysis on comments with extremely negative and extremely positive responses to examine the semantic relationships between character design and emotional characteristic terms. We also performed a content analysis of comments about Miquela and Shudu to analyze the perception differences regarding the two character designs. The results indicate that form elements (e.g., voice, face, and skin) and behavioral elements (e.g., speaking, interviewing, and reacting) are vital in eliciting users' emotional responses. Notably, in the negative responses, users focused on the humanization aspect of voice and the authenticity aspect of behavior in speaking, interviewing, and reacting. Furthermore, we found differences in the character design elements and characteristics that users expect based on the VI's field of activity. As a result, this study suggests applications to character design to accommodate these variations.

This study introduced trust dimension as a mediating variable and analyzed in order to investigate the empirical mechanism on the process of leader's emotional intelligence which is a emotional factor to produce organizational effectiveness. Based on the empirical analysis, first of all, this study found whether the team leader's emotional intelligence gives an influence on the subordinate's trust in leader. Secondly, this study examined the multidimensionality of trust by selecting subordinate's cognition-based trust and affect-based trust on the team leader as mediating variables between team leaders's emotional intelligence and subordinate's affective commitment, organizational citizenship behavior. I found the theoretical implications based on this study; first, from the view on cognition-based and emotion-based trust, the integrated verification of the process of the trust in leader as a mediating role, second, verification of the relationship between leader's emotional intelligence and trust in leader which was not studied before, third, the methodological try to prevent from the common method bias problem through the evaluation of a team leader on a subordinate's organizational citizenship behavior. This study also suggested the ways to apply those theoretical implications to human resource management.

With the advance of digital technology, new methods which acquire color information and combine it with various contents are emerging. Color has some effect on emotion while it gives some information as component of an image. In addition, change in emotion and sensation from color stimulus makes some change in cognition. This research investigate the effect of color overlay on cognition depending on emotional state. With this goal, subjects consisting of 10 men and 10 women solved some problems with color overlay of red, orange, and green after watching short video clips which intend to induce target emotion. Experimental results show that red color overlay under positive emotion significantly reduces the average score of solving problems, while green overlay under negative emotion significantly increases it. It is also analyzed that there is not statistically significant difference in cognitive function with color overlay while it is significantly better under positive emotion than negative emotion without color overlay.

In this paper, we propose the active rule system applying with emotional margin for power saving control. The proposed system in this paper is a part of the system which derives smart power saving by adjusting the illuminance using active rules within compromising the user's emotion. For this, we set the specific range of standard illuminance and the lower bound of user's emotional margin of illuminance based on measurements and analysis, and use these data in design of active rules. And then, we design and implement the active rule system using mobile agent. The mobile agent in the proposed system migrates to the destination sensor nodes, acquires and transmits sensor data according to the purpose and needs through the active rules, and directly executes the actions corresponding to the optional events(changed sensor data and/or time etc.). And then, we show the potential applicability of the proposed active rule system in various active sensor network applications through the interaction with the rule base and mobile sensor network middleware system.

The purposes of this study were to: a) provide evidences concerning the effects of emotional leadership b) examine the impacts of emotional leadership on employee-related variables, 'job satisfaction', 'organizational commitment', 'organizational performance' and 'turnover intention', and c) identify a conceptual framework underlying emotional leadership. A survey was conducted from August 23 to November 3, 2005 to collect data from mid-level managers in food service company headquarters (N=219). Statistical analyses were completed using SPSS Win (12.0) for descriptive, reliability, factor and correlation analyses and AMOS (5.0) for confirmatory factor analysis and structural equation modeling. The main results of this study were as follows. First, the managers gave the highest point to their leaders in the emotional leadership competence 'organizational awareness : reading the currents, decision networks, and politics at the organizational level' and gave the lowest point in the emotional leadership competence 'influence: wielding effective tactics for persuasion'. Second, the means of job satisfaction was above the midpoint (3 points). Employees' job satisfaction with 'coworkers' was relatively high. However, the extents of satisfaction with 'payroll' 'promotion', and 'work environment' were relatively low. Third, the organizational commitment was above the midpoint (3 points). In the organizational commitment, 'loyalty' factor was higher than 'commitment' factor. Fourth, the means of organizational performance was above the midpoint. The highest organizational performance variable was 'internal efficiency; trying to reduce cost' and the lowest organizational performance variable was 'internal fairness ; equitable treatment and all are treated with respect with no regard to status and grade'. Fifth, most respondents intended on 'thinking of quitting ; towards turnover process'. Sixth, the test of hypothesis using structural equation modeling found that emotional leadership produced p[Isitive effects on job attitude and job performance. Emotional leadership enhanced job satisfaction and organizational commitment, and in turn, employees' attitude positive effects on organizational performance; emotional leadership also had a direct impact on organizational performance

본 연구에서는 시각자극에 의하여 안구 운동 시 뇌의 학습, 인지, 집중력을 활성화시키기 위하여 무한대 회로($\infty$)를 이용하여 연구를 수행하였다. 뇌파 유도를 하기 위한 무한대 회로($\infty$)는 LED 모양을 하고 있으며 이것을 실행시키기 위하여 LabView 프로그램을 사용하였다. 시각자극을 제시하기 위하여 LED의 수를 각각 26, 51, 101개로 구분하였고 점멸 시간은 50, 150, 250㎳로 하였다. 시각 자극 제시 조건의 변화에 의하여 유도되는 뇌파를 Fz, Cz, Pz, Fpl, O1, O2 부위에서 측정한 결과 LED의 수가 적고 점멸 시간이 길어질수록 $\beta$파의 비율이 증가하는 경향을 보였다. 이 결과는 LED의 점멸 움직임의 불연속적인 요인에 의하여 $\beta$파의 비율이 증가했을 것이라 생각한다. 본 연구를 통하여 얻어진 결론을 역이용하여 원하는 뇌파를 유도할 수 있는 시각 제시 방법이 완성되어 진다면, 이는 뇌기능 장애 환자의 재활이나 학습 장애의 아동에게 있어 효과적인 방법이 될 것이다.
