감정을 포함하고 있는 음성은 청자로 하여금 화자의 심리상태를 파악할 수 있게 하는 요소 중에 하나이다. 음성신호에 포함되어 있는 감정을 인식하여 사람과 로봇과의 원활한 감성적 상호작용을 위하여 특징을 추출하고 감정을 분류한 방법을 제시한다. 음성신호로부터 음향정보 및 운율정보인 기본 특징들을 추출하고 이로부터 계산된 통계치를 갖는 특징벡터를 입력으로 support vector machine (SVM) 기반의 패턴분류기를 사용하여 6가지의 감정- 화남(angry), 지루함(bored), 기쁨(happy), 중립(neutral), 슬픔(sad) 그리고 놀람(surprised)으로 분류한다. SVM에 의한 인식실험을 한 경우 51.4%의 인식률을 보였고 사람의 판단에 의한 경우는 60.4%의 인식률을 보였다. 또한 화자가 판단한 감정 데이터베이스의 감정들을 다수의 청자가 판단한 감정 상태로 변경한 입력을 SVM에 의해서 감정을 분류한 결과가 51.2% 정확도로 감정인식하기 위해 사용한 기본 특징들이 유효함을 알 수 있다.

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.

The purpose of this study is to investigate the effect of emotional intelligence on job satisfaction and organizational commitment of dietitians in elementary schools. The correlation analysis was conducted in order to examine the relationship among emotional intelligence, job satisfaction and organizational commitment. Multiple regression analysis was conducted to determine the impact of dietitians' emotional intelligence on job satisfaction and organizational commitment. The analysis results are as follows. Emotional intelligence showed a statistically significantly positive correlation with job satisfaction and organizational commitment. Especially, emotional perception and emotional intelligence had a correlation coefficient of 0.774, the highest but emotional management and organizational commitment had a correlation efficient of 0.254, the lowest. As for the effect of dietitians' emotional intelligence on job satisfaction and organizational commitment, emotional thinking promotion gave a statistically significantly positive impact on dietitians' organizational commitment. As dietitians' emotional function of thought and emotional management got higher, their job satisfaction got higher. As dietitians' emotional function of thought got higher, their organizational commitment got higher as well. These results recommend that development of an emotional intelligence promotion program to effectively control factors related to dietitians' emotional intelligence is necessary to enhance their job satisfaction and organization commitment in the future.

In general, the size of index set of the emotion-based control is smaller than that of the logic-based control. And thus, by using the concept of emotion we can control the behavior's patterns of multiple persons more softly from the global viewpoint. The principle just mentioned, we think, can be applied on fille general purpose system. In this paper we presented a n : n negotiation model in the deal based on emotional agent. Through the emotional layers of the agents we tried to show that the flexible control of the negotiation process is possible especially in case of dynamic environment.

This study was based on previous ones that demonstrate how social exclusion leads to a desire for physical warmth. Research was conducted using odor-induced emotions to predict social exclusion, leading to a pursuit of emotional warmth and avoidance of emotional distance. For this purpose, a preliminary study sought to select odors perceived to be emotionally warm and emotionally distant, after which two experiments verified differences in odor preference between the social exclusion group and the control group. Results indicated that individuals who have experienced social exclusion had a stronger preference for warm odors and a weaker preference for cold odors compared to those who have not been socially ostracized. This study has theoretical value in terms of expanding the social exclusion-induced desire for physical warmth into the emotional dimension as well as examining the avoidance of emotional coldness, which had been overlooked in previous research studies. This also leads to practical implications for comfort foods, character emotions, emotional-space design, and emotions for artificial-intelligence chatbots.

Currently, ICT is widely used in caring for the elderly living alone and preventing the disappearance of the elderly with dementia. Therefore, in this study, based on the government policy direction for the 4th industrial revolution, the use of AI technology-based care services, which are gradually increasing in community care, was sought to explore the current status and prospects for utilization and activation.AI speakers and caring robots, services that can be used for community care, help solve various problems experienced by the elderly, and are also used to relieve lack of conversation or loneliness by adding emotional functions. In order to activate community care using AI technology in the future: First, there is a need for continuous education to familiarize the elderly with AI devices and 'user experience (UX) design' for the elderly. Second, it is necessary to use human-centered technology that has a complementary relationship and enables emotional mutual relationships rather than using function-oriented technology. Third, it is necessary to solve ethical problems such as guaranteeing the user's right to self-determination and protecting privacy.

In this paper, we discussed learner's capability enhancement education suitable for the age of artificial intelligence (AI) using game analysis and archival research based on the 2016 Google Deepmind Challenge match between AI that possessed the finest deep neural networks and the master Baduk player that represented the best of the human minds. AlphaGo was a brilliant move that transcended the conventional wisdom of Baduk and introduced a new paradigm of Baduk. Lee Sedol defeated AlphaGo via the 'divine move and Great idea' that even AlphaGo could not have calculated. This was the triumph of human intuition and insights, which are deeply embedded in human nature as well as human courage and strength. Convergence science education that cultivates student abilities that can help them control machines in the age of AI must be in the direction of developing diverse human insights and positive spirits embedded in human nature not possessed by AI via implementing hearts-on experience and topophilia education obtained from the nature.

The recent COVID-19 pandemic has witnessed the rapid growth of the fitness app market, with weight management apps occupying a substantial market segment. In connection, a growing body of research has been conducted to examine design elements aimed at fostering user motivation and long-term engagement, without considering user characteristics, which are critical to understanding user responses to weight-loss apps. Therefore, to fill this research gap, this research focuses on the weight stigma of users and strives to examine what affects such user characteristics have on the weight-loss apps. The main findings of this study is that higher help-seeking intention and willingness to use weight management apps among those who show high weight stigma consciousness than those with low consciousness. This study further shows the interaction effects between weight stigma consciousness AI types of service. This research provides new insights on how to design elements of weight-loss apps targeting both non-stigmatized and stigmatized users. It shows that in designing public applications, feeling-based AI that considers the psychological needs of users may be more effective for individuals with weight stigma.
