Due to the recent pandemic and the development of ICT technology, the use of non-face-to-face and unmanned systems is expanding, and it is very important to understand emotions in communication in non-face-to-face situations. As emotion recognition methods for various facial expressions are required to understand emotions, artificial intelligence-based research is being conducted to improve facial expression emotion recognition in image data. However, existing research on facial expression emotion recognition requires high computing power and a lot of learning time because it utilizes a large amount of data to improve accuracy. To improve these limitations, this paper proposes a method of recognizing facial expressions using age and gender, which are image meta information, as a method of recognizing facial expressions with even a small amount of data. For facial expression emotion recognition, a face was detected using the Yolo Face model from the original image data, and age and gender were classified through the VGG model based on image meta information, and then seven emotions were recognized using the EfficientNet model. The accuracy of the proposed data classification learning model was higher as a result of comparing the meta-information-based data classification model with the model trained with all data.

The purpose of this study was to identify the effects of self-image congruity and alternative attractiveness on commitment and store loyalty when customers purchase clothes in a department store. A survey was conducted for this study and 530 answer sheets were analyzed using structural equation modeling. The results are as follows: First, self-image congruity has a significant positive effect on affective commitment and continuance commitment. Second, alternative attractiveness has no significant effect on affective and continuance commitment. Third, both affective commitment and continuance commitment have a significant effect on behavior intentions such as repurchase intention, word-of-mouth, and willing to pay more. Fourth, affective commitment has a stronger effect on word-of-mouth intention and willing to pay more than does continuance commitment. Finally, continuance commitment has a stronger effect on repurchase intention than does affective commitment.

Social network service users actively express and share their feelings about social issues and content of interest through postings. As a result, the sharing of emotions among individuals and community members in social network is spreading rapidly. Therefore, resulting in active research of emotion analysis on posting of users. However, There is insufficient research on emotion analysis for postings containing various emotions. In this paper, we propose a method that analyzes the emotions of an Instagram posts using hashtags and images. This method extracts representative emotion from user posts containing multiple emotions with 66.4% accuracy and 81.7% recall, which improves the emotion classification performance compared to the previous method.

브랜드 이미지가 마케팅에 미치는 영향이 커지면서 기업은 브랜드 가치 형성을 위해 온/오프라인 PR활동과 함께 브랜드 웹사이트를 적극적으로 활용하고 있다. 또한 학계와 관련 업계에서는 소비자들의 웹사이트의 이용 경험이 브랜드이미지 형성에 미치는 영향에 대하여 많은 연구를 진행해 왔다. 그러나 이와 반대로 웹사이트의 평가에 있어서 선 경험된 브랜드 이미지가 사이트의 평가에 영향을 미칠 수 있음에 대해서는 거의 연구되지 않았다. 본 연구에서는 브랜드 인지도와 브랜드 이미지를 통해 형성되는 브랜드 충성도-특히, 감정적 브랜드 충성도(Affective brand loyalty)-가 웹사이트의 사용자 경험에 있어서 디자인과 인터랙션디자인에 대한 감정적 평가에 미치는 영향에 대해 조사하였다. 이를 위하여 중국의 대학생, 대학원생 70인을 대상으로 중국에서 판매되고 있는 자동차 브랜드 8개를 선정하여 브랜드 충성도와 웹사이트의 사용자경험 평가에 대한 상관관계를 조사하였다.

This study was conducted to verify the relationships among the image of middle-low price chain hotels, service quality, consumption value, and customer emotion by using the AMOS 22.0 statistic package program. Confirmatory factor analysis and structural equation modeling methods employed for identifying the formulated hypothesis model. According to results, first, it is seen that the image of middle-low price chain hotels has positive effect on the service quality. Second, the image of middle-low price chain hotels has positive effect on the consumption value, and the consumption value has positive effect on the service quality. Third, the service quality does not have positive effect on the customer emotion. Last, the image of middle-low price chain hotels has positive effect on the customer emotion. In this study, we attempted to establish the management strategy device of middle-low price chain hotels by analyzing how the image of middle-low price chain hotels affect the service quality, consumption value, and customer emotion. As a result, when it comes to the service quality according to the image of middle-low price chain hotels, the conviction, in other words, the belief of the hotel staffs was the biggest one. In addition, when it comes to the consumption value according to the image of middle-low price chain hotels, the functional value, the kind service of the hotel staffs was seen as the highest satisfaction. More practical and theoretical implications for developing marketing strategy in context of middle-low price chain hotels has been suggested in conclusions.

This research deals with expressive definition of visual contents by using the distance between a subject and a screen resolution, and what changes affect the emotion of those looking at the expressive definition. A visual image captured from a HDTV screen was shown to the 61 students attending a university in the Busan area and SAM evaluation method was used to measure 3 different emotions such as pleasant, arousal, and dominance. While comparing different resolution, looking at high resolution contents rather than low resolution resulted in a direction of pleasant, arousal, and dominance. Also showing a different resolution than consistently showing the same resolution had a more volatile emotional effect. Aftermath multiple comparison resulted in a tendency for emotions to become unpleasant and un-arousal when high resolution contents were shown and then switched to a low resolution contents. There was no result of any significance in the control variables. Also on the aftermath multiple comparison on short, medium and long distance between the subject and the screen resolution, short distance had a bigger pleasant, arousal, and dominance emotional numbers than the rest. In a multiple variable verification result, a resolution and the distance of happiness and excitement showed a positive correlation.

This study examined the characteristics of brain's reaction pattern concerning the preference for product images and compared them with the result of subjects' intuitive evaluation of their preference for the same materials. Two tests were conducted; the first one that calculated comfort properties based on brainwave measurements in order to examine the impression given by the images of products presented separately, one-by-one, and the second one that had subjects evaluate the preference directly by comparing the images of all products simultaneously. The first test was titled 'Independent Cognitive Response' and the second test, 'Relative Cognitive Response', and their characteristics were as follows. In the 'Independent Cognitive Response', the state of emotion was expressed in absolute values based on the comparison with the information accumulated through the subject's own experience and the feeling expressed as 'pleasant' or 'unpleasant' persisted as absolute values. In the 'Relative Cognitive Response', the state of emotion relative to the information of other images compared in the stage of perceiving the images was expressed, and in this case, the state of emotion described as 'calm' or 'excited' acted as relative values.

본 작품은 보통의 애니메이션에서 나타나는 캐릭터는 등장하지 않고 거의 시종일관 미술적으로 창조된 이미지들의 애니메이션이다. 흔히 구체적인 스토리에 의해 등장하는 캐릭터들의 움직임 및 그 감정을 표현하는 애니메이션과 본 작품과 같이 구체적인 대사나 캐릭터에 의존하지 않는 이미지애니메이션을 비교해 보면 이미지애니메이션은 감독의 의도와는 상관없이 관객에 따라 느끼는 감정이 다양할 수 있다. 이는 추상미술을 감상하는 것과 같이, 보는 이에 따라 전혀 다르게 해석할 수도 있지만, 전체적인 분위기에서 감독이 의도한 것이 무엇인가를 생각하면서 감상하는 것도 좋은 감상법일 수 있다.

According to the growth of the service industry, stresses from emotional labor workers have been emerging as a social problem, thereby so-called the Emotional Labor Protection Act was implemented in 2018. However, insufficient substantial protection systems for emotional workers emphasizes the necessity of a digital stress management system. Thus, in this paper, we suggest a stress detection system for customer service representatives based on deep learning facial expression recognition. This system consists of a real-time face detection module, an emotion classification FER module that deep-learned big data including Korean emotion images, and a monitoring module that only visualizes stress levels. We designed the system to aim to monitor stress and prevent mental illness in emotional workers.
