  • This paper examines the economic factors that are related to the dynamics of the variance risk premium, and specially, which economic factors are related to the forecasting power of the variance premium regarding future index returns. Eleven general economic variables, eight interest rate variables, and eleven sentiment-associated variables are used to figure out the relevant economic variables that affect the variance risk premium. According to our empirical results, the won-dollar exchange rates, foreign reserves, the historical/implied volatility, and interest rate variables all have significant coefficients. The highest adjusted R-squared is more than 65 percent, indicating their significant explanatory power of the variance risk premium. Next, to verify the economic variables associated with the predictability of the variance risk premium, we conduct forecasting regressions to predict future stock returns and volatilities for one to six months. Our empirical analysis shows that only the won-dollar exchange rate, among the many variables associated with the dynamics of the variance risk premium, has a significant forecasting ability regarding future index returns. These results are consistent with results found in previous studies, including Londono (2012) and Bollerslev et al. (2014), which show that the variance risk premium is related to global risk factors.

  • Cultural heritage teaching and learning, which uses cultural heritage as educational content, has not been sufficiently analyzed and studied based on clear educational theories so far. Among educational theories, constructivism is a theory in which learning is a process of constructing learning contents determined by learners' individual experiences and interests, and the result is evaluated as a confirmation of whether or not they have the ability to carry out the process. Cultural heritage is a lively and interesting social and cultural product, and it is an educational content that has sufficient educational function and meaning for a textbook. It is considered to be a very meaningful study to apply the constructivist educational theory to the educational contents of cultural heritage with these characteristics. Based on this awareness of the problem, this study examined the characteristics and principles of constructivist teaching and learning, the characteristics of cultural heritage, and the principles of constructivist teaching and learning on a theoretical basis. In addition, from the perspective of constructivism, the current cultural heritage teaching and learning was analyzed and problems were derived. Based on this, the direction of cultural heritage teaching and learning is that the cultural heritage teaching and learning process should be learner-centered, the teaching and learning principle should be cognitive conflict, the teaching and learning content should be in the form of task solving, and teaching and learning activities should be cooperative. presented. In addition, an example of a program was presented to specifically show the actual state of teaching and learning of cultural assets from the perspective of constructivism. Cultural heritage teaching and learning research from the perspective of constructivism will be an opportunity to discover new meanings of cultural heritage that we have not yet found, and it will also serve as an opportunity to present and establish the direction of cultural heritage teaching and learning, which has been barren until now.

  • The reality of this study is that, in accordance with the development trend of human body art, art makeup and semi-permanent makeup are emerging as promising industries in the beauty industry among beauticians, and awareness of professional skill improvement is gradually increasing over time. Accordingly, interest in semi-permanent makeup has increased not only among beauticians who specialize in beauty industry or learn semi-permanent makeup, but also at beauty academies where they learn many beauty techniques, and this trending technology has been promoted at international beauty competitions by holding skill competitions for beauty technicians who specialize in semi-permanent techniques. As a venue for exchanging information about education, it is expected that synergistic effects such as dissemination of the education system can be expected. Korea's rapid industrial development has brought about great changes in the supply and demand of professional and detailed skilled manpower and in the formation of manpower in terms of technical level according to industrial development, and the skills and professional skills of beauty beauticians have improved due to the excellence of the professional education qualifications of beauticians and high skill evaluations. This had a significant impact on self-development and led to a re-recognition of the importance of efforts to achieve skilled skills.

  • Beyond the first nuclear age, which pitted the United States and the Soviet Union against each other, we are now in the second nuclear age, in which the decision-makers of nuclear weapons are diversified among countries large and small. India and Pakistan, two such countries, are antagonistic toward each other and possess nuclear weapons, but their nuclear posture and nuclear strategies are different. The examples of these two countries can provide clues to the future nuclear posture of North Korea, which faces South Korea. In particular, Pakistan's chosen posture of pre-emptive deterrence is a highly offensive nuclear posture that threatens to use nuclear weapons against an adversary to deter aggression. This is an option that can be accomplished even with a small nuclear arsenal that can be used as a first strike, so it seems to be the optimal posture for a nuclear-powered Pakistan to choose in response to an Indian threat. North Korea, which is outgunned by the United States and South Korea, is likely to continue to threaten to use nuclear weapons preemptively like Pakistan. However, it is expected to be defensive and quite conservative, like India, until it actually uses them to maintain its regime.

  • We rethink human existence as a assemblage through intersectionality by comparing autopoiesis and sympoiesis systems with reference to science fiction protagonists such as Ghost in the Shell, Neuralink, Camille, a genetic hybrid, and San Ti against the background of neo-materialism. Our findings reveal that, first, radical sympoiesis is characterized by the dissolution of individuals and boundaries, and attempt to explain existence solely through heterogeneous linkage and fusion; second, by ignoring the capacity for autonomous thinking at the individual level, they are unable to fully recognize the destructive nature of hybrid co-production or to develop practical responses to it. Third, we suggest that if the very survival of humanity is threatened by heterogeneous linkage, we should pay more attention to our identity as autonomous members of a autopoietic system rather than to heterogeneous sympoietic networks and we should also pay attention to the role of individual units in stabilizing self-regulation. Through this study, we aimed to contribute to overcoming the limitations of neo-materialism by arguing that it is likely to fail to provide an adequate practical vision if it is limited to describing the hybrid connections that recur through the intersection of beings, and by urging us to define the identity of the human species from a new perspective by utilizing various SF stories that trigger the imagination of destructive interactions between beings, and to explore the autopoiesis in terms of symbiotic interactions based on a certain level of boundary and self-regulation.

  • This study employs photovoice research methodology to investigate adolescents' experiences in sibling relationships and to analyze the impact of sibling interactions on their development and growth. The participants comprised eight high school students with one sibling (four males and four females) residing in the Incheon region. The research process encompassed several stages: participant recruitment, orientation, photovoice activity (focus group interviews), data analysis, and conclusion derivation. During the photovoice activity, participants engaged in a narrative process of photographing, interpreting, and discussing their experiences. The narratives were categorized into four primary themes: structure and environment, emotional interactions, roles, and parental subsystems. The conclusions drawn from the study are as follows: First, the similarity formed in sibling relationships during adolescence contributes to psychological stability. Second, roles and expectations based on birth order can cause stress for adolescents, indicating the need for equitable role adjustments within the family. Third, conflict in sibling relationships is crucial for enhancing problem-solving and social relationship skills. Lastly, consistent parenting attitudes significantly affect the emotional well-being of siblings. This study emphasizes the significance of fostering a deeper understanding of human development and family relationships through an exploration of adolescent sibling dynamics within home economics education.

  • Consumer happiness is the ultimate goal pursued by consumers, and it is important to understand the variables related to it. This study analyzed the mediating effects of sense of community and relational consumption to study the relationship between loneliness and consumer happiness. For the study, 288 university students were randomly sampled and an online survey was conducted from May 4 to May 31, 2023. For data analysis, serial mediation analysis was performed using Hayes' SPSS Process Macro (version 3.5.2) model 6, and Bootstrapping was performed to verify the significance of indirect effects. The results of the analysis are as follows: First, in the relationship between loneliness and consumer happiness among students, the sequential mediating effect of sense of community and relational consumption was statistically significant. Second, it was found that the level of loneliness of students seeking financial support has a negative effect on relational consumption, and relational consumption has a positive effect on consumer happiness. Third, when seeking psycho-emotional support, loneliness has a positive effect on a sense of community, a sense of community has a positive effect on relational consumption, and relational consumption has a positive effect on consumer happiness.

  • The purposes of this study are to obtain an in-depth understanding of the experiences of novice Home Economics teachers during their first year and to extract meaning from the experiences. The Photovoice was used as a research methodology. Participants in the study included three novice Home Economics teachers who passed the 2022 secondary school teacher recruitment examination and began working at middle schools in the Seoul metropolitan area from March 2022. Data were collected from February 2022 to January 2023, involving one written interview, nine monthly Photovoice projects, and two Focus Group Interviews. Thematic analysis was utilized for data analysis. The narratives of novice Home Economics teachers were divided into the narratives as 'Home Economics teacher' and as 'Novice teacher'. As being Home Economics teachers, participants constructed their narratives around three themes: 'Home Economics is a practical discipline', 'Home economics teachers are agents of change', and 'Home Economics is undervalued in the school.' Furthermore, the sub themes of the 'novice teachers' narrative included 'Now it's the real beginning', 'Teaching is a wonderful profession', and 'I will become a good teacher.' The significance of this study lies in the in-depth exploration of the lived experiences of novice Home Economics teachers during their first year and broadening the use of Photovoice as a research and teaching strategy.

  • Objectives: This study was carried out to understand the seroprevalence and risk factors for severe fever with thrombocytopenia syndrome (SFTS) among the Korea National Park Service (KNPS) workers. Methods: We used the stored serum samples (763) and survey results collected from the previous investigation on scrub typhus and Lyme disease among the KNPS workers during 2016-2017. The serum samples were analyzed by double-antigen sandwich enzyme-linked immunosorbent assay, which was used to test the total antibody including IgG and IgM. Results: The SFTS seroprevalence among the KNPS worrkers was 1.4%. In multivariate logistic analysis, the national park exploration programs (odds ratio, 3.48; 95% confidence interval, 1.01-12.01) was significantly associated with the seroprevalence of SFTS. Conclusion: This study was the first serological study of SFTS among forestry workers in South Korea. Although the KNPS workers are at a high-risk group of SFTS, the prevention activities related to the working environment and habit was insufficient. Thus, systematic prevention education and training for the KNPS workers need to be strengthened.

Reviewing the Concept of Gender Equality and Femininity in Daesoon Thought: Focusing on Meritorious Deeds and Implementing a Practice on the Based on the Resolution of Grievances for Women (대순사상의 남녀평등이념과 여성성 재조명 - 여성해원의 원리로 본 공덕과 실천을 중심으로 -)

  • This study focuses on reviewing the concepts, roles, meanings, and values ascribed to females and femininity as observable in Daesoon thought and in Feminist theory. Especially with regards to the process of achieving gender equality through the resolution of grievance for females in Daesoon thought, the study draws positive and desirable roles within this practice by specifically examining good deeds performed by females and practical roles that females play. By doing so, this study finds a way to go from the world of mutual contention to the world of resolving grievances that have arisen due to the oppression of yin and the encouragement of yang. First wave feminism can be summarized as the inclination for equality. In Daesoon thought concerning this and from standpoint of females, the most ideal image of woman is one of a female Perfected Being who is unified with Dao and has thereby achieved perfection of her humanity apart from gender. In the Later World (Hucheon), people can get results based on their hard work regardless of gender. The enlightenment of Dao is such that it is not important to distinguish between males and females. Both of them can be 'unified with dao'. Therefore, despite the similarity, the concepts of equality in first wave feminism and the resolution of grievance for women have differences in terms of their ideal vision of equality. The representative claim in second wave feminism is 'consideration' and, in this context, 'consideration' has pronounced feminine characteristics. In Daesoon thought, this sense of 'consideration' is related to the concept of 'Jamojijeong', a term that refers to motherly affection. However, it is not simply a virtue of females and mothers, but rather the value of 'Yin (pronounced in Sino-Korean as 'Eum')' called 'Eumdeok (hidden virtue)'. Jamojijeong means that people should behave in a modest way and this helps them achieve their aims. It is also closely related with 'femininity' in the sense of Eum. One of processes spreading it socially is to propagate virtue (Podeok) and if harmony is achieved through it, then 'right yin and right yang' emerge as the precondition by which Pyeong Do (Pacification of Tao) can be realized. Furthermore, because the aspect of Pyeong is a cosmic process, it has distinct differences from the social aims of feminism and the worldly aims of other numerous ideologies. In proceeding from the Former World (Seoncheon), an era of mutual contention, to the Later World, an era of mutual beneficence, it is essential to emphasize the connection between 'harmony (Hwa)' and 'propagating virtue' as the starting point from which the perspective of Daesoon thought aiming at the principle of 'Pyeong' and 'Hwa' emerges. Herein one can discover that the realization of Daesoon thought is based on the vitalization of the feminine value of 'Jamojijeong'.
