This study aims to empirically measure K-pop fans' content and the extent of online activities. To achieve the purpose of the study, the researchers identify the statistically significant online activities that determine the intensity of fan attachment toward K-pop artists. Further, the research confirms the relative importance of various meaningful online activities. Consequently, we can develop the K-pop Online Activity Index (KOAI) model and apply it to this index model empirically for each respondent. We found that the model consists of five online activities of K-pop fans: whether joining the fan club or not, whether paying per view V live+ or not, whether watching VODs associated with artists or not, the degree of fan club writing, the degree of watching a lot on YouTube to improve the value of my artists. This study has practical significance in that it allows K-pop marketers to improve their marketing performance by providing content that will enable them to more efficiently and effectively allocate marketing resources to various online activities to get fan responses. It allows accumulating academic knowledge to understand the behavior in the field of online behavior for K-pop fans.

The aim of this study is to clarify the psychological effects of walking in the urban forest and to examine how the effects differ in accordance with individual personality. The study subjects comprised 18 male Japanese university students ($21.0{\pm}0.8$ years old). These subjects were instructed to walk predetermined 20-min courses in the urban forest and the city (control). Three questionnaires (POMS, STAI-S, and SCL-90) were administered to assess the subjects' psychological responses. The KG's Daily Life Questionnaire was used to examine the subject's personalities for presence of the Type A behavior pattern. The study found that walking in the urban forest improved the participants' positive mood and decreased their negative mood, anxiety, and other negative mental symptoms. Moreover, Type B subjects showed a bigger change than Type A subjects on the SCL-90's obsessive and compulsive scale. Our results supported the premise that walking in the urban forest has relaxing effects, and that these effects can differ in accordance with the subject's personality characteristics.

The purpose of this study was to investigate how primary caregivers of children with developmental disabilities aged 6 to 18 years perceived on tele-music programs in which their children participated during COVID-19. A total of 83 caregivers who voluntarily agreed to participate in this study responded to a survey either on-line or in person and 67 questionnaires were included in the final analysis after deleting 16 incomplete responses. The results showed that tele-music programs were rated somewhat suitable for distance learning but that there was still a need for adult assistance to help children with developmental disabilities participate in the program. When comparing the perceptions of caregivers who participated in remote general education versus who participated in tele-music program, significantly higher level of program engagement and positive responses from a child were perceived with tele-music program. The caregivers who participated in tele-music program showed significantly greater willingness to participate in tele-music therapy in the future than those who did not. The findings of this study presents information on how tele-music therapy has been implemented to children with disabilities and what can be considered for the the development of a tele-music therapy program.

This paper reviewed the necessity of a information and communication technology (ICT)-based smart livestock system as a development strategy for the animal life industry in the future. It also predicted the trends of livestock and animal food until 2050, 30 years later. Worldwide, livestock raising and consumption of animal food are rapidly changing in response to population growth, aging, reduction of agriculture population, urbanization, and income growth. Climate change can change the environment and livestock's productivity and reproductive efficiencies. Livestock production can lead to increased greenhouse gas emissions, land degradation, water pollution, animal welfare, and human health problems. To solve these issues, there is a need for a preemptive future response strategy to respond to climate change, improve productivity, animal welfare, and nutritional quality of animal foods, and prevent animal diseases using ICT-based smart livestock system fused with the 4th industrial revolution in various aspects of the animal life industry. The animal life industry of the future needs to integrate automation to improve sustainability and production efficiency. In the digital age, intelligent precision animal feeding with IoT (internet of things) and big data, ICT-based smart livestock system can collect, process, and analyze data from various sources in the animal life industry. It is composed of a digital system that can precisely remote control environmental parameters inside and outside the animal husbandry. The ICT-based smart livestock system can also be used for monitoring animal behavior and welfare, and feeding management of livestock using sensing technology for remote control through the Internet and mobile phones. It can be helpful in the collection, storage, retrieval, and dissemination of a wide range of information that farmers need. It can provide new information services to farmers.

This study was conducted to explore parenting experiences for mothers of adolescent children. Participants in the study were 7 primary caregivers of children in the first to third grades of middle school in the Seoul area, and in-depth interviews were conducted from September to November 2019. After recording the interviews of each participant, the transcripts of verbal words and documents that were the summary of the interview were collected as data. In this study, the participants' perceptions of experiences and actions were analyzed by Smith & Osborn (2003)'s interpretative phenomenological method, which allows researchers to make meanings. As a result of data analysis, 6 major topics and 25 sub-themes were derived. The results derived from the parenting experiences of mothers of adolescents are largely six types: the implications of spending time with their children, unnatural act, the aesthetics of expression, the way to recharge energy, the mental heritage that they want to leave for their children, and resilience. The research results of this study can be presented so that they can learn the healthy responses and interaction of care-givers in a preventive educational dimension, as it provides both generality and specificity of how mothers should interact with their adolescent children in the field of clinical practice.

The purpose of this study was to compare participants' perceived emotion following harmonic changes in music. In this study, 144 participants, aged 19 to 29 years, listened to music online that included low to high harmonic progression in tonal music (major-minor). After listening to each piece of music, participants were asked to rate 4 items using a 7-point Likert scale: emotional potency, arousal, degree to which the harmony impacted the listener's emotions, and listener's preference for the music. There were significant differences between each of the four items upon the level of harmonic progression. When the participants were divided into two groups (i.e., those with a background in music and those with no background in music), there was a significant difference between the groups in terms of emotional potency, but there was no significant interaction effect. This study confirmed that various emotional responses in listeners can be induced by controlling the exogenous variables in musical excerpts. Based on this, it is expected that the harmonic progression level can be provided to the client to be used as an effective therapeutic tool in music therapy intervention.

If a company's actions to save or avoid taxes are judged to be tax evasion rather than legal tax action by the tax authorities, the company will not only pay tax but also non-tax costs such as damage to corporate image and stock price decline due to a series of tax evasion-related news articles. Therefore, this study measures the frequency of occurrence of tax evasion controversial keywords in internet news portal as a factor to measure the severity of the case, and analyzes the effect of the frequency of occurrence on corporate value. In the Korean stock market, we crawl related articles from internet news portal by using keywords that are controversial for tax evasion targeting top companies based on market capitalization, and generate a time series of the frequency of occurrence of keywords about tax evasion by company and analyze the effect of frequency of appearance on book value versus market capitalization. Through panel regression and impulse response analysis, it is analyzed that the frequency of appearance has a negative effect on the market capitalization and the effect gradually decreases until 12 months. This study examines whether the tax evasion issue affects the corporate value of Korean companies and suggests that it is necessary to take these influences into account when entrepreneurs set up tax-planning schemes.

Successor representation (SR) is a model of human reinforcement learning (RL) mimicking the underlying mechanism of hippocampal cells constructing cognitive maps. SR utilizes these learned features to adaptively respond to the frequent reward changes. In this paper, we evaluated the performance of SR under the context where changes in latent variables of environments trigger the reward structure changes. For a benchmark test, we adopted SR-Dyna, an integration of SR into goal-driven Dyna RL algorithm in the 2-stage Markov Decision Task (MDT) in which we can intentionally manipulate the latent variables - state transition uncertainty and goal-condition. To precisely investigate the characteristics of SR, we conducted the experiments while controlling each latent variable that affects the changes in reward structure. Evaluation results showed that SR-Dyna could learn to respond to the reward changes in relation to the changes in latent variables, but could not learn rapidly in that situation. This brings about the necessity to build more robust RL models that can rapidly learn to respond to the frequent changes in the environment in which latent variables and reward structure change at the same time.

The purpose of this study was to investigate families' responses and attitudes and the experiences of Korean LGBT individuals after revealing their sexual identity and sexual orientation and to determine how families' attitudes affected the mental health of these individuals. For this purpose, in-depth interviews were performed with 12 male and female LGBT participants, ranging from 19-30 years of age, who resided in Seoul and metropolitan areas, and reported coming out to or being outed by their families. One-to-one interviews were carried out using semi-structured questions, and the data from the interviews were analyzed using consensual qualitative research (CQR). Most of the families had very negative responses and attitudes to the participants coming out and exhibited rejection or avoidant attitudes; only a few of the families responded with receptive attitudes. As a result, the LGBT participants reacted with friction and coping behaviors, such as persuasion, participation in professional counseling, abandonment or avoidance, and running away from home. Most of the effects of the families' attitudes on the participants were negative psychological effects, such as anger, sadness, a sense of alienation, depression, anxiety, fear, trauma, helplessness, lowered self-esteem, alcohol dependence, and suicidal ideation and attempt, while receptive attitudes provided a sense of stability. For all participants, they reported that they were more likely to be hurt by their families' negative attitudes than by social attitudes. This study is significant because it provides framework for specifying families' attitudes and LGBT individuals' experiences after coming out in Korean society. It also outlines LGBT individuals' coping behaviors, psychological difficulties, and the process of coming out and provides suggestions for individuals to overcome. The results are expected to help counselors create practical strategies to better understand LGBT individuals and the psychological difficulties they may experience and provide proper interventions while counseling both the individual and the family.

The purpose of this study tries to show the effectiveness of integrated theater education for low-grade students who lack social skills with the direction of art education based on 'theatrical and educational theater' and 'theater therapy' in the revised curriculum in 2015. To do this, the researcher organized a theater camp organized by the social, cultural and arts education institute in Seoul for a total of 12 low-grade elementary school students for four weeks, and had a presentation session. In addition, the researcher observed the behavioral changes of the participating children to verify the social development of the theater education and after the conclusion, the final results were obtained through the in-depth interviews of the participants' parents and teachers. As a result, it was found that Social Skills Rating System(SSRS)' test, teachers' observation logs, interviews, and responses of participating children, which are the main subjects of this activity, had a great effect on improving their sociality and relationship. Therefore, the researcher tried to prove through this paper that theater education is effective in enhancing social skills as creative, personality and convergence education in preparation for the 4th industrial era and that it is important to solve communication problems such as the absence of human relationships.
