In this paper, we propose a method of recognizing emotions using PPG sensor which measures blood flow according to emotion. From the existing PPG signal, we use a method of determining positive emotions and negative emotions in the frequency domain through PSD (Power Spectrum Density). Based on James R. Russell's two-dimensional prototype model, we classify emotions as joy, sadness, irritability, and calmness and examine their association with the magnitude of energy in the frequency domain. It is significant that this study used the same PPG sensor used in wearable devices to measure the top four kinds of emotions in the frequency domain through image experiments. Through the questionnaire, the accuracy, the immersion level according to the individual, the emotional change, and the biofeedback for the image were collected. The proposed method is expected to be various development such as commercial application service using PPG and mobile application prediction service by merging with context information of existing smart phone.

Purpose: This study aimed to evaluate the effects of a combined biofeedback and brief emotion regulation (C-BABER) program for sexually abused adolescents. Methods: This study employed a non-equivalent control group pretest-posttest design. The participants included 26 sexually abused adolescents from eight Sunflower Centers of South Korea-with 13 in the experimental group and 13 in the control group. The experimental group received four sessions of the individual C-BABER program, each lasting 60 minutes. Results: Compared with the control group, sexually abused adolescents in the experimental group exhibited significant score differences in traumatic symptoms, including depression (Z = - 2.24, p = .025), dissociation (Z = - 2.21, p = .027), anxiety (Z = - 2.02, p = .044), and posttraumatic stress (Z = - 2.01 p = .045); and impulsivity, including positive urgency (Z = - 3.35, p = .001) and negative urgency (Z = - 2.28, p = .023). Additionally, the experimental group exhibited significant score differences in meta-mood, including emotional attention (Z = - 2.45, p = .014), emotional clarity (Z = - 2.30, p = .021), and emotional repair (Z = - 2.28, p = .022); and emotional regulation modes, including emotional suppression (Z = - 2.65, p = .008) and cognitive reappraisal (Z = - 1.98, p = .047). Regarding bio-attention, significant changes were identified in the experimental group for the bio-attention rate and attention maintenance time in the posttest compared to the pretest (p = .001). Conclusion: The C-BABER program for sexually abused adolescents is effective in decreasing traumatic symptoms and impulsivity, and in improving meta-mood, emotional regulation mode, and bio-attention. Therefore, we recommend providing sexually abused adolescents the C-BABER program to help them regulate their emotions and effectively adapt to their lives.

The purpose of this study is to increase understanding of the library use behavior and preferences of the elderly by exploring positive and negative experience factors in the use of public libraries by the elderly. To this end, the Critical Incident Technique (CIT) was applied and individual in-depth interviews were conducted with elderly people who use public libraries. Analysis of the collected data was conducted by applying the constant comparison method, and 12 categories of positive experience factors and 12 categories of negative experience factors were derived under four areas: data, service-program, environment-facility, and emotion. Based on these results, suggestions were made regarding public library services for the elderly.

In the modern society, psychological diseases and impulsive crimes due to stress are occurring. In order to reduce the stress, the existing treatment methods consisted of continuous visit counseling to determine the psychological state and prescribe medication or psychotherapy. Although this face-to-face counseling method is effective, it takes much time to determine the state of the patient, and there is a problem of treatment efficiency that is difficult to be continuously managed depending on the individual situation. In this paper, we propose an artificial intelligence emotion management system that emotions of user monitor in real time and induced to a table state. The system measures multiple bio-signals based on the PPG and the GSR sensors, preprocesses the data into appropriate data types, and classifies four typical emotional states such as pleasure, relax, sadness, and horror through the SVM algorithm. We verify that the emotion of the user is guided to a stable state by providing a real-time emotion management service when the classification result is judged to be a negative state such as sadness or fear through experiments.

This essay studied the acting theories of Diderot, Delsarte, Meyerhold, and Artaud to know the historical formation of 'sign acting' and its theoretical and aesthetic appropriateness. The sign acting so far discussed shows the repetitive patterns of idea as follows. The sign acting (1) emphasizes the physical expression such as gesture and movement, (2) assumes that the physical expression functions as a sign evoking special emotion and thought, (3) thus recommends the imitation of the outer sign, (4) uses a tableau for the effective reception of outer sign, (5) aims for the spectator oriented aesthetics as it stresses the result of outer sign rather than the creative process of a role, (6) assumes that the emotional reaction or the intellectual understanding springs from the physical experience, (7) thus emphasizes the physical language rather than speech, (8) can attain the appropriateness of physical language by the recent theories of cognitive science. Besides having such commonness, the sign acting also reveals the individual differences. For instance, the intended sign for Diderot and Delsarte was the sign of emotion, for Meyerhold the stylized sign of circus and acrobatics, and for Artaud the spiritual sign. If Diderot and Meyerhold demands the cool consciousness for the correct sign acting, Artaud's sign acting tends to pursue the state of trance. And if Diderot, Delsarte, and Meyerhold think the sign acting on the level of sensory appeal, Artaud insists that the sign acting should dismantle the spectator's sense. As such the discussion of sign acting shows both recurrent ideas and new visions, forming an unity out of diversity. Perhaps the sign acting is a matter of practice before we consider it as a theory. It is not only supposed to have been existed practically since ancient theatre, but also used by actors consciously and unconsciously in expressing certain emotion and thought. We need to study the sign acting more academically, considering its long history and aesthetic potentials. In fact the sign acting has been an essential element of acting, in spite of bad reputation judging it as a banal and worn-out style. It is true that the sign acting, in the worst case, could produce a stereotypical expression. It was this aspect of sign acting that caused a fierce negative reaction of the realists who sought the natural expression based upon psychological truth. Of course the sign acting has a serious problem when it stays banal and artificial. But we need to see this issue from a different perspective. What is the natural expression of emotion? How is it free from the learned way of expression? In some respect, we use, in reality, a learned expression of emotion that could be accepted socially. For instance, when we attend a funeral, we use the outer sign of mourning gestures learned socially. If a semiotic expression pervades various aspects of our life, the acting, being the representation of life, seems not to be free from codified expression. The sign acting could be used consciously and unconsciously in all kinds of acting.

The purpose of this study is to explore the effect of individual difference variables on emotional change after indirect trauma among elderly. After Sewolho Accident in South Korea, we invested emotion of the elderly and collected the same variables from the same sample two months after the accident. In study, we examined how social support, depression, future time perspective, and active aging affect emotion of elderly and which emotions are affected by these four variables. As a result, when compared to the counterpart, those with lower perceived social support, future time perspective, and active aging and higher depression level experienced lower levels of positive emotion and higher level of negative emotion after indirect disaster experience. Overall, we could certify that social support, future time perspective, and active aging functioned as protective factors, whereas depression functioned as a risk factor. Implications and limitations for our findings were discussed.

YouTube realistically shows fake news and biased content based on facts that have not been verified due to low entry barriers and ambiguity in video regulation standards. Therefore, this study aims to analyze the influence of the media and YouTube on individual behavior and their relationship. Data from YouTube and Twitter are randomly imported with selenium, beautiful soup, and Twitter APIs to classify the 31 most frequently mentioned keywords. Based on 31 keywords classified, data were collected from YouTube, Twitter, and Naver News, and positive, negative, and neutral emotions were classified and quantified with NLTK's Natural Language Toolkit (NLTK) Vader model and used as analysis data. As a result of analyzing the correlation of data, it was confirmed that the higher the negative value of news, the more positive content on YouTube, and the positive index of YouTube content is proportional to the positive and negative values on Twitter. As a result of this study, YouTube is not consistent with the emotion index shown in the news due to its secondary processing and affected characteristics. In other words, processed YouTube content intuitively affects Twitter's positive and negative figures, which are channels of communication. The results of this study analyzed that YouTube plays a role in assisting individual discrimination in the current situation where accurate judgment of information has become difficult due to the emergence of yellow media that stimulates people's interests and instincts.

Contemporary era has witnessed a diversity of emotion and emotions being expressed through consumption. This paper examines the relationship between social paradigms and emotional design by means of literature study. In sections 2 and 3, I examine the prevalent social paradigms and the concept/development of emotional design. In section 4, I show the correspondence between social paradigms and specific types of emotional design. More specifically it is shown that "pluralism and decentrality" has led to fun design, individual design and participative design; "emotional revolution" has given rise to multi-sensory design, design with positive feelings, design with negative feelings and aesthetic design; "non-materialistic values" have their correspondence in design as performance and story-telling in design; and "organic worldview" finds its expression in ecological design with a wellness emphasis, and in interactive emotional design.

In existing method, research for landscape resource is driven by professional (or with the participation of local people at Tokenism level), and usually hinder local residents from reflecting their appreciations on the landscape resources in their own ways and eventually ends up with indistinguishable landscape planning. To avoid this, a profound understanding of what landscape they experience in their daily life and how they perceive it should be empirically analysed carefully. The purpose of this study is to apply walking behavior as a method to examine local residents' subjective perceptions and consider its usability. The researcher walked the site(Sucheongri) with the residents, carrying a GPS device, taking photographs of the landscape objects they described, and recording the relevant explanations. After gathering photographs and explanations which represent the research participants' individual subjective perception, the researcher analysed the explanation using open coding, based on grounded theory. By the analysis, 117 landscape objectives are identified and 18 reason factors for landscape perception were deduced from the explanation. Those factors could be classified as 'positive feeling inducing' and 'negative feeling inducing', and also as 'personal emotion based' and 'community based emotion'. By comparison between feeling map by conventional method and feeing map by new method, usability of new method was empirically reveled. Walking behavior makes it easier for researcher to get more abundant data in quantitative aspect and profound understanding with affection of respondent by allowing them to 'go beyond' the perceptions they remember. Finally new method with walking gives professionals a contextual understanding of a place and more resident-oriented plans and management on sites.

The 'Sliver-Spoon-Discourse' is currently witnessing growing complaints about the polarization and a sense of despair among many young people in Korean society. The 'Sliver-Spoon-Discourse' that compares one's subjective socioeconomic status to a spoon implies a sense of psychological superiority or deprivation. The present study empirically tested the current popular 'Sliver-Spoon-Discourse' based belongingness and explored how subjective socioeconomic status may affect the psychology of young people. This study examined the effects of subjective socioeconomic status on individual relative deprivation and subjective well-being. Data were collected from 307 undergraduate students enrolled at universities located in Seoul with both parents alive. The findings of this study were as follows. First, student respondents reported moderate levels of subjective socioeconomic status, relative deprivation, and subjective well-being. Second, after controlling for respondents' gender, age and family income, the students' subjective socioeconomic status was negatively associated with their level of relative deprivation. Finally, after controlling for respondents' sociodemographic characteristics, the students' subjective socioeconomic status was not significantly related to all the three sub-factors of life satisfaction, positive emotion and negative emotion as well as total subjective well-being. The results indicate that 'Sliver-Spoon-Discourse' based belongingness may instigate relative deprivation of young people without affecting their subjective well-being. The implications of the results are discussed for youth programs and policies.
