The main objective of our research is analyzing user's emotional changes while using a product, to reveal the influence of usability on human emotions. In this study we have extracted some emotional words that can come up during user interaction with a product and reveal emotional changes through three methods. Finally, we extracted 88 emotional words for measuring user's emotions expressed while using products. And we categorized the 88 words to form 6 groups by using factor analysis. The 6 categories that were extracted as a result of this study were found to be user's representative emotions expressed while using products. It is expected that emotional words and user's representative emotions extracted in this study will be used as subjective evaluation data that is required to measure user's emotional changes while using a product. Also, we proposed the effective methods for measuring user's emotion expressed while using a product in the environment which is natural and accessible for the field of design, by using the emotion mouse and the Eyegaze. An examinee performs several tasks with the emotion mouse through the mobile phone simulator on the computer monitor connected to the Eyegaze. While testing, the emotion mouse senses user's EDA and PPG and transmits the data to the computer. In addition, the Eyegaze can observe the change of pupil size. And a video camera records user's facial expression while testing. After each testing, a subjective evaluation on the emotional changes expressed by the user is performed by the user him/herself using the emotional words extracted from the above study. We aim to evaluate the satisfaction level of usability of the product and compare it with the actual experiment results. Through continuous studies based on these researches, we hope to supply a basic framework for the development of interface with consideration to the user's emotions.

Background and Purpose: The emotions of people at various stages of dementia need to be effectively utilized for prevention, early intervention, and care planning. With technology available for understanding and addressing the emotional needs of people, this study aims to develop speech emotion recognition (SER) technology to classify emotions for people at high risk of dementia. Methods: Speech samples from people at high risk of dementia were categorized into distinct emotions via human auditory assessment, the outcomes of which were annotated for guided deep-learning method. The architecture incorporated convolutional neural network, long short-term memory, attention layers, and Wav2Vec2, a novel feature extractor to develop automated speech-emotion recognition. Results: Twenty-seven kinds of Emotions were found in the speech of the participants. These emotions were grouped into 6 detailed emotions: happiness, interest, sadness, frustration, anger, and neutrality, and further into 3 basic emotions: positive, negative, and neutral. To improve algorithmic performance, multiple learning approaches were applied using different data sources-voice and text-and varying the number of emotions. Ultimately, a 2-stage algorithm-initial text-based classification followed by voice-based analysis-achieved the highest accuracy, reaching 70%. Conclusions: The diverse emotions identified in this study were attributed to the characteristics of the participants and the method of data collection. The speech of people at high risk of dementia to companion robots also explains the relatively low performance of the SER algorithm. Accordingly, this study suggests the systematic and comprehensive construction of a dataset from people with dementia.

교통사고의 원인은 크게 차량요인, 도로환경요인, 인적요인으로 구성되는데 과거에 비해 비약적으로 발전한 기술로 인하여 현재는 교통참가자들의 교통행동이 가장 중요한 원인으로 주목받고 있다. 최근 활발하게 연구가 이루어지고 있는 정서는 인간의 판단과 행동결정에서 그 역할이 중요시 되고 있다. 이에 운전자가 운전행동을 판단하고 결정할 때에도 정서가 영향을 줄 것으로 예상되며 운전자의 정서가 운전행동에 어떠한 영향을 주는지 밝혀내는 것이 본 연구의 목적이다. 분석결과 긍정적 정서는 운전행동에 큰 영향을 주지 않지만 부정적 정서의 경우 안전운전 요인 및 여유운전 요인과는 부적(-) 상관관계를, 난폭운전 요인 및 법규위반 요인과는 강한 정적(+) 상관관계를 갖는 것으로 나타났다. 또한 회귀분석을 통해 적합도가 가장 높은 2차 함수 모형을 구축하였다. 본 연구는 운전자의 정서와 운전행동과의 관계를 확인했다는 점에서 의의가 있으며 교통사고를 줄이기 위한 정책을 수립하고 결정할 때뿐만 아니라 효과적인 운전자 교통안전교육의 기초연구로서 의미가 있다고 할 수 있다.

Neiging Medicine(內經醫學) based on Yin-Yang and Five elements was the main stream of Korea Traditional Medicine until the end of 19th century. And the establishment of Sasang Constitutional medicine. In this paper, author proved that the Yin-Yang of Sasang Constitutional Medicine was different from that of Neiging Medicine and that explained the Yin-Yang of Sasang Constitutional Medicine as our own medicine. After considering the philosophical and medical background of Sasang Constitutional Medicine, and author researched the Yin-Yang of ontology, structure, function, symptoms in Sasang Constitutional Medicine. Also we compared this with that of Neiging medicine. The results were as follows 1. Neiging Medicine was based on the Yin-Yang and Five elements centering on the nature and Sasang joy, and pleasure centering on the human. 2. The ontology of Sasang Constitutional Medicine were the mind as a unitary substance, the mind and body as a dual substance, and affair, mind, body, and objects as a four substance which were the basic theory of philosophy. 3. Sasang Constitutional Medicine explained social phenomenon with a four substancial structure consisted of affairs, mind, body, and objects, a complex four substancial structure consisted of heaves, human, nature and order, and a three dimension structure including time. 4. On the other hand Neiging Medicine recognized seven emotions as five emotions, Sasang Constitutional Medicine recognized seven emotions as qi, nature, and emotions which consisted of sorrow, anger, joy, and pleasure. The qi had an effect on internal and external part of body and the nature and the emotion had an effect on the upward and downward of body. 5. It was taked great importance to control the up and down balance and the internal and external balance in Sasang Constitutional Medicine instead of reinforcing and reducting method of Neiging Medicine. 6. The Yin-Yang of Korean Traditional Medicine developed centering on the human from centering on the nature and Sasang Constitutional Medicine was a practical medicine compared with Neiging Medicine.

This study describes a system for human sensibility evaluation using PPG(photoplethysmogram) signal and biofeedback algorithm to respond the bad(negative) mood. For this objective, PPG signals for two emotional states(positive/negative) are collected. To evoke the test emotions, happy(or joyful) and sad(or irritating) movie files are collected and played in subjects' monitor. From the acquired PPG signal, the heart rate variability(HRV) is calculated. Using the HRV and its FFT spectra, the human sensibility is evaluated. Since the heart is a representative organ which is controlled by the autonomic nervous system(ANS), the ANS may reflect the changes in emotion. The biofeedback algorithm is designed with motion image player interacting with the results of the sensibility evaluation. It was shown that HRV was changed according to the subject's emotions. Accordingly, the sensibility evaluation test showed feasibility of the our method.

As people are getting interested in themselves ever than before, the value of culture industry which can satisfy their emotions has been considered much more important. According to this, in terms of the 'space', it is better to represent 'space' not just as a functional space, but the human-centered and making human and nature together. In this society, the most human-centered design can be achieved by pursuing value which is friendlier to nature. And it is sure that the interior design that completes life quality as well as emotions of human will be common in near future. There already has been a try 'Green interior' in subway station in variety ways, and now it is needed to make indoor display in Seoul subway station different in order to satisfy human emotions. If culture space in Seoul subway station applied eco-element interacts with indoor environment, it is surely expected that people have better feeling on subway station as well as help eliminate negative elements which underground have had. In culture space, there are many advantages for displaying space into 'nature', that is, natural space represents the best comfortable and agreeable space, and future-oriented design when it gets interacted with environment. Application of 'Green interior' in Seoul subway station makes special place ness by its symbol and image, so that it derives people to have more natural and comfortable movement distance in subway station, offers more comfortable and cozy place as well. Furthermore, it makes people very moved by experiencing the most special culture space that they have ever had.

The goals of this study were to examine how children's recognition of various emotions, emotion expression, and social interactions among their peers differed according to their attachment styles. A total of 65 three to five years old children completed both attachment story-stem doll plays and a standard emotion recognition task. Trained observers documented children's valence of emotion expression and social interactions among their peers in the classroom. Consistent with attachment theory, children who were categorized as secure in the doll play were more likely to express positive emotions than children who were categorized as avoidant in the doll play. Children who were categorized as avoidant in the doll play were more likely to express neutral emotions among their peers than children who were categorized as secure and anxious in the doll play. The findings of this study contribute to the general attachment literature by documenting how attachment security plays a crucial role in having positive emotions in ordinary situations. It does so by also demonstrating how different attachment styles are associated with children's qualitatively different patterns of emotion processing, especially in terms of their expression of emotions.

Postmodernism, a cultural movement which occurred in the mid-20th century, avoided functional form, one of the features of modernism, and pursued post-rational and post-centric pluralistic thought which puts human emotions in importance. Postmodernism set a high value on emotional instincts of humans and focused on creation of empathy. It includes scepticism of rationalism and indicates the significance of emotional and psychological instincts of humans, or 'emotions'. Along with the big change in that time, more dynamic and unprecedented indoor spaces had appeared. Nigel Coates, who had taken various kinds of artistic activity from the early 1980s to the late 1990s, had tried to make a new approach of objet-focused emotional spaces. Such an approach made in the time when science and technology had rapidly developed and social structure had changed was considerably fresh, liberal, and futuristic. He interpreted spaces by escaping from realistic intentions and communicating with drawings, and designed object-focused emotional spaces by actively employing objets on the basis of ideas. He tried to make emotional sharing between the public and spaces through objet, and showed unique spaces in his own way by reinterpreting the meanings of spaces and stimulating human emotion. This study was intended to look into his artworks to show his way of approaching objets, and to find an application plan and the future possibility of the plan.
