The purpose of this study was to analyze the factors that demographic factors, radiation knowledge level, and radiation awareness could be affecting the benefits of radiation. From July 2022 to July 2023, after receiving consent to participate by using the link of Naver through Social Network Service (SNS) for the general public, 312 people were surveyed by self-registration method without collecting personal information. The questionnaire consisted of a total of 25 questions following demographic factors (5 questions including age group by life cycle, sex, monthly household income, residence), radiation knowledge level (8 questions including basic physical, biological effects, radiation protection technology), radiation awareness (12 questions including risk, management, benefit). Independent sample T-test and ANOVA tests were performed for significant differences in the average radiation awareness between variables, and hierarchical regression was performed to identify influencing factors on radiation benefits. As a result, the benefit of radiation was significantly high among the radiation awareness, but the awareness of the danger of radiation was insufficient to the level of recognizing it as safe. Men had significantly higher awareness of radiation management and benefits than women, and the awareness of radiation management was significantly higher in the middle class with a monthly household income of 4.31 million won or more. The higher the knowledge level of radiation, the higher the awareness of the benefits of radiation. The factors that had a positive effect on radiation benefits were the high level of radiation knowledge and awareness of radiation management.

Purpose: This study was conducted to examine the structural relationships among mothers' parenting practices, child's self-esteem, and child's well-being and to explore the mediating effects of mothers' parenting practices on child's well-being through child's self-esteem. Research design, data, and methodology: Data from the 10th and 13th waves of the Korean Child Study Panel were used for the study, and data from 1,213 mothers and child were analyzed using SPSS 28.0 and the R statistical program. Results: First, in the relationship between the mother's parenting practices, the child's self-esteem, and well-being, the mother's authoritative parenting practices were positively correlated with the child's self-esteem and well-being. Second, the mother's authoritative parenting practices in preschool directly influenced the child's self-esteem in late school, and the child's self-esteem directly influenced the child's well-being. Third, mothers' authoritative parenting practices in the preschool years had a static effect on child's Well-being through the mediation of child's Self-Esteem in the late school years. The direct mediation effect of the Child's Self-Esteem was confirmed. Conclusions: To promote child's Well-being, mothers should adopt authoritative parenting practices with affection and control and try to improve child's self-esteem. In addition, programs that focus on improving child's self-esteem can be expected to enhance school-aged child's well-being.

The purpose of this study is to determine the impact of social network sports community consciousness on loyalty and sports attitude. In order to achieve this research purpose, the population of the study was selected as adult men and women over the age of 20 who are active in the social network sports community in 2022. The sampling method used cluster random sampling to select a total of 300 people, 150 men and 150 women, as research subjects. The survey tool used was the questionnaire method, and the questionnaire whose reliability and validity had been verified in previous studies at home and abroad was used by requoting, modifying, or supplementing it to suit the purpose of this study. It was also structured on a 5-point scale. Frequency analysis, factor analysis, reliability analysis, simple regression analysis, and multiple regression analysis were performed on the collected data using the statistical program SPSS Windows 20.0 Version. The results obtained through this process are as follows. First, social network sports community consciousness was found to have a partial effect on loyalty. Second, social network sports community consciousness was found to have a partial effect on sports attitudes. Third, social network sports community loyalty was found to have a partial effect on sports attitudes. Considering these results, various activities such as decision-making process, relationship formation, and opinion expression of modern people are carried out by the O-line community. In addition, while in the past it was a format that led from offline activities to online activities, currently, there are more and more formats that lead from online activities to offline activities. Therefore, modern people's SNS sports community activities provide many experiences, which creates a sense of community and sports attitudes are formed based on this. This can be said to lead to loyal activities.

본 연구는 소셜 감성(social sentimental)을 긍정 및 부정적 의견으로 구분하여 이들 의견이 개별 기업의 주식수익률에 미치는 영향이 비대칭적인지(asymmetric) 분석하였다. 이를 위하여 한국거래소에서 활발하게 거래되고 트위터 의견도 충분한 기아차, 아모레퍼시픽, 포스코, 한국전력 등 4개 기업을 분석대상으로 하였다. 주요 분석 결과는 다음과 같다. 첫째, 긍정적 의견은 개인투자자의 거래 비중이 상대적으로 낮은 아모레퍼시픽의 주식수익률에는 영향을 주지 못한 반면 나머지 3개 기업의 주식수익률에는 유의한 양(+)의 영향을 주었다. 둘째, 부정적 의견은 4기업의 주식수익률에 모두 유의하게 음(-)의 영향을 주는 것으로 나타났다. 특히 부정적 의견이 긍정적 의견보다 주식수익률에 미치는 영향이 더 크게 나타났으며, 이는 투자자들이 손실회피 성향 등으로 수익보다 손실에 더 민감하기 때문으로 보인다. 본 연구는 트위터의 긍정 또는 부정적 의견이 주식수익률에 비대칭적(asymmetric)으로 영향을 미치는 것을 발견하였으며, 이는 트위터의 의견을 투자자 심리(sentiment) 대용변수(proxy)로 활용할 수 있음을 보여준다.

K-POP의 가파른 성장세에 따라 댄스 콘텐츠 산업이 확산되는 추세이다. 최근 SNS의 보급이 증가하면서 자신의 댄스 영상을 촬영하고 공유하기도 한다. 그러나 춤을 처음 접하는 댄스 초보자들은 동영상을 보며 혼자서 춤을 출 때, 객관적인 피드백을 받기 어려워 춤동작을 습득하기 쉽지 않다. 본 논문에서는 MediaPipe를 활용하여 안무 영상과 사용자의 춤 영상을 비교하고 올바르게 동작을 따라 하고 있는지 검출해 주는 시스템에 대해 기술한다. 본 연구에서는 웹캠이나 카메라로 촬영한 사용자 영상과 안무 영상 간의 춤동작 유사도를 코사인 유사도와 COCO OKS를 활용해 계산하여 사용자에게 색상 지표(Color Map)를 기반으로 한 피드백을 주는 방식을 제안한다. 본 시스템을 통해 사용자의 춤동작에 대한 객관적인 피드백을 시각적으로 받을 수 있으며 초보자들도 정확한 춤동작을 습득할 수 있을 것으로 기대한다.

With the increase in online shopping and delivery food consumption since the pandemic, solving environmental problems caused by single-use packaging has become an important issue. 'Upcycling' is a combination of 'Upgrade' and 'Recycle', and it is the rebirth of obsolete or discarded objects by adding new value to them, and there are currently various upcycled products on the market. In order to activate upcycling, consumers' awareness of the environment and their values for consumption are very important. This study aims to investigate the influence of students' environmental concern, environmental experience, and consumption value on their purchase intention of upcycled products. Based on the results of previous studies on environmental concern, environmental experience, and consumption value, hypotheses were set, and a survey was conducted among university students nationwide to test the hypotheses. The results of this study are as follows First, environmental concern has a significant positive effect on purchase intention of upcycled products. It can be seen that the more environmental concerns such as global warming and waste disposal problems increase, the more positive attitudes toward upcycled products increase. Second, the research hypothesis that environmental knowledge will have a positive effect on the purchase intention of upcycled products is rejected. It was found that environmental knowledge is acquired through environmental education and many SNS, but it does not have a direct effect on the purchase intention of upcycled products. Third, it was found that the consumption value of college students has a positive effect on the purchase intention of upcycled products by increasing their positive perception of upcycled products. Fourth, college students' purchase intention of upcycled products has a positive effect on their behavioral intention to purchase upcycled products. The results of the study provide implications for relevant organizations such as universities and companies to effectively design upcycling-related education. It is also expected to have a positive impact on the use of upcycled products by providing basic information on the characteristics of consumers who purchase upcycled products.

Purpose - The purpose of this paper is to examine whether firms use social media to disseminate good news to various stakeholders thereby enhancing corporate social performance (CSP). Design/methodology/approach - This study collected data from various databases such as Korea Economic Justice Institute (KEJI) Index, VALUESearch, and TS2000, and such social media platforms as Instagram and Meta (formerly known as facebook). The sample of this study includes 3,474(firm-year) observations from 799 unique Korean firms between 2013-2022. This study conducts fixed effect panel regression analysis to test the hypotheses. Findings - First, we found both corporate use of social media, and the number of uploaded corporate news on social media were positively related to CSP. We also found that positive user reactions to the news on social media were positively related to CSP. Second, we examine the moderating roles of firm age in the relationships described above. The results show that firm age strengthens both the relationship between number of uploaded news on social media and CSP, and the relationship between positive user reactions to news on social media and CSP. Research implications or Originality - This study extends the social media research in the management literature by investigating how corporate use of social media, number of uploaded corporate news on social media, and the user reactions on the news on social media affect corporate social performance. For a practical implication, our results allow the stakeholders to better predict corporate future CSP. They suggest that ceteris paribus, firms that use social media actively, vis-a-vis firms that do not use social media actively, are more likely to get good CSP scores. They also suggest that such beneficial effects of social media will become more prominent as companies get older.

Make-up culture has recently emerged as a major trend among adolescents, and their knowledge of this culture is acquired from their peers. Adolescence is a period in which peer relationships have a significant effect on individuals' behavior and self-esteem. Also, adolescents are conscious of others' evaluation because they only want to exhibit their ideal-self. They generally apply make-up for various reasons; pursuing ideal beauty, concealing their insecurities and improving their own self-esteem. The purpose of this study is to design and implement the MUSE(Make-Up & Self-Esteem) project, to reduce self-esteem disparity based on make-up status. Ten female adolescents(mean age=17.0 yrs, SD=1.49) participated in the MUSE project, in which the participants gradually reduced their make-up steps and posted feelings about this on SNS. Also, events were designed for the participants to enhance their interest and become more focused on themselves without make-up. Resultantly, it was obeserved that after the project, the gap between the particiapnts' self-esteem with and without make-up decreased. More specifically, there was no significant difference in self-esteem with make-up before and after participating in the project, but a significant increase was observed in self-esteem without make-up after the project. Although the participants were mostly satisfied with the project, individual interviews were conducted to obtain feedback regarding how the project could be improved. The participants suggested that future project could be developed within their own peer group and the term of the project could be extended so that the participants could become accustomed to daily make-up reducing steps.
