The issue of children′s education is the most important issue for all households in Korea. It is certain that the issue of private education for children is the first issue among household′s issues. This study is to recognize the current pictures of household primate education of Korean households. Also, whether the expenditure of private education effect the economic will-being of household. The data for this study was"the 3th Korean Labor Panal", conducted by Lobor in Korea. The sample was 1950 households from the panel data. The results of this study was as following: 1. The mean of monthly private education expenditure was 149273won for all households and 217,100won for households with high school students. 2. Almost 70% households had economic burden for private education expenditure. 0% households had no economic burden. 3. The factors of influencing the level of economic burden for private education were mother′s education level, mother′s job, the number of children, living location, monthly income, total asset of household′s. The factors of influencing the amount of monthly private education expenditure positively were living in 4. The economic well-being of household was analyzed by socio-economic variables, household′s financial variables, monthly private education expenditure, the level of economic burden of private education. The economic well-being were sub-categorized 4 divisions; the level of economic problem, the level of satisfaction for household′s income, the level of satisfaction for general living, the level of subject economic condition)

The growth of cheap, industrial, mass-production-so-called "fast fashion"-has led to dramatic increases in levels of consumption. Inexpensive products tend to foster unsustainable consumption behaviors, which negatively impact the environment and increase pressure to obtain goods at lower and lower prices; this, in turn, has the competitive effect of decreasing wages. This study focused on the concept of socially responsible consciousness in relation to fashion products. Environmental and labor issue concerns were employed as major variables. Empirical data were collected from males and females, between the ages of 10 and 50. Demographic differences were found in SR consciousness. For example, participants in their 10s, 40s, and 50s had higher levels of SR consciousness than those in their 20s and 30s. In addition, consumers' levels of environmental and labor issue concerns had varying effects on the criteria they used to select clothing. Product category type was also an influential factor. Moreover, the analysis showed that SR consciousness was less important in the apparel industry than in the food sector. The study also found an attitude-behavior link in relation to the concept of SR consciousness. The link was stronger for environmental concerns than for labor issue concerns. This study aimed to develop a better understanding of current customers' characteristics and levels of SR consciousness.

In this study, a zero-crossing spike current issue in a totem-pole bridgeless power factor correction (PFC) converter is comprehensively investigated for the first time. Spike current occurs when input voltage crosses zero, becomes a noise source, and causes severe common mode emission issues. A generation mechanism for electromagnetic interference (EMI) is presented to investigate the EMI problem caused by zero-crossing issue, and a noise spectrum due to this issue is predicted by a theoretical analysis based on the Fourier coefficient of an approximate spike current waveform. Furthermore, a noise reduction method is proposed and then improved to reduce the spike current. Experimental measurements are implemented on a GaN-based totem-pole bridgeless PFC converter, and the spike current can be effectively suppressed through the proposed method. Furthermore, the noise spectrums measured without and with the reduced zero-crossing spike current are compared. Experimental results validate the analysis of the noise spectrum caused by the zero-crossing spike current issue.

Purpose - This study aims to develop machine learning models to predict administrative issue designation in KOSDAQ Market using financial data. Design/methodology/approach - Employing four classification techniques including logistic regression, support vector machine, random forest, and gradient boosting to a matched sample of five hundred and thirty-six firms over an eight-year period, the authors develop prediction models and explore the practicality of the models. Findings - The resulting four binary selection models reveal overall satisfactory classification performance in terms of various measures including AUC (area under the receiver operating characteristic curve), accuracy, F1-score, and top quartile lift, while the ensemble models (random forest and gradienct boosting) outperform the others in terms of most measures. Research implications or Originality - Although the assessment of administrative issue potential of firms is critical information to investors and financial institutions, detailed empirical investigation has lagged behind. The current research fills this gap in the literature by proposing parsimonious prediction models based on a few financial variables and validating the applicability of the models.

This paper presents an efficient method for generating informative apparel fit comments by analyzing 122 fit reviews found in 7 menswear patternmaking textbooks, which include both domestic and foreign sources. The fit reviews for menswear were categorized into top and bottoms, and the expressions varied based on body parts, causes, and fit issue appearances. The causes of fit issues could be attributed to size errors and structural errors in both top and bottoms. Both top and bottoms had fit reviews concerning unique body types, but it could cause trouble among learners as both were based on unclear criteria for body type classification and lacked relevant explanations. Common fit issue appearances included compound wrinkles, pulling wrinkles, sagging wrinkles, and garment being away from the body. No clear correlation was observed between the causes of fit issues and specific appearances. Limitations were identified in using textbooks as educational data, such as inconsistent solutions for different body types or fit issues, and the presence of ambiguous visual materials. As a result, strategies such as categorizing fit issue appearances, providing 3D visual examples with subcategorized causes, body types and parts could enhance quality of fit reviews and improve fit outcomes in clothing production systems.

The term 'Nepo-baby' refers to someone whose career benefits from family connections. Criticism of the so-called Nepo-baby issue is growing, especially among the MZ generation, who highly value fairness. In this study, we explored how fashion consumers perceive the Nepo-baby issue and its impact on fashion brands. Consumers are more likely to compare themselves to Nepo babies and may experience feelings of powerlessness, unfairness, relative deprivation, and loneliness. These perceptions can lead to negative feelings toward the brand, resulting in disappointment. Our research hypotheses were tested using SPSS 26.0 and AMOS 23.0. Fashion brands promoting Nepo babies affect consumers' self-perceptions of powerlessness, unfairness, relative deprivation, loneliness, and negative feelings. Brand disappointment was tested using a structural equation model. Using a multi-group path analysis, we investigated consumers' perceptions of the Nepo-baby issue and general brand stories. Our research results reveal the significant impact of controversial Nepo babies on negative feelings toward fashion brands and brand disappointment.

This study conducted a qualitative research based on interviews with school teachers and instructors operating external activities about how the management of one's own appearance influence the changes in subjective happiness and self-esteem by focusing on maladjusted students of two alternative schools and ordinary middle and high schools in Gyeongsangnam-do province. Happiness refers to a positive emotion that can be felt continuously throughout life such as life satisfaction, good experience, and positive way of thinking. The sense of happiness is the satisfaction that one feels by interpreting and evaluating his or her experience in a positive way and can be defined as the positive emotions that can be felt when one perceives and uses the strengths and resources that he or she has. Although the self-esteem is formed, changed, and developed throughout life, the self-awareness and self-evaluation develop more actively than other stages of development particularly in adolescence, and the adolescents with low self-esteem are faced with more serious behavioral, scholastic, and psychological issues. I hope the results of this study not only help current adolescents at risk to improve their self-esteem but also become a chance to see the issue of adolescents at risk as a part of social issue instead of limiting the issue as personal or domestic issue by expanding the application scope of the results to adolescents in middle schools and high schools who have the potential of going astray in order to approach the issue on the level of the entire society.

이 연구에서는 해양환경에 대한 언론의 의제설정 경향을 연도별로 분석하여, 해양환경이 국내 언론을 통해 어떻게 의미화 되는지를 분석하였다. 지난 10년(2005-2014년)간 국내 4개 종합일간지(동아 중앙 경향 한겨레)에 해양환경에 관해 보도된 기사에 대해 R 프로그램과 넷마이너 프로그램을 활용하여 언어 네트워크 분석을 실시하였다. 연구 결과, 국내 언론에서 해양환경은 경제적 차원에서 의미화되었다. 지난 10년간 연도별 구분 없이, 언론은 해양환경에 대한 '개발'이슈를 주요하게 다루고 있는 것으로 나타났다. 해양 환경의 개발을 중심으로 다양한 '계획'과 단위 '사업'들이 중요한 상관관계를 가진 영역으로 다루어졌다. 하지만 해양환경의 '보전'이슈는 국내 언론에서 주요 의제로 언급되지 않았다. 해양환경은 효과적인 보전을 기반으로, 이와 동시에 합리적인 개발이 필요한 분야이다. 개발이슈만을 지나치게 부각하는 국내 언론보도의 의제설정경향은 해양환경을 개발의 대상으로 인식하는 데 막대한 영향을 미친다. 향후 해양환경 분야에 대한 언론보도의 방향성과 정보제공의 시사점에 대해 논의하였다.

The goal of today's environmental education is to enhance the understanding of the serious of environmental problems and the interactions among environment. With this perspectives people need to be aware that environmental education is no longer a liberal arts in university education, but play a vital role within the socio-cultural context. This study was performed to assess the changes in the university student's attitudes and consciousness in real life after the education of a point at issues of environmental problems. For this study 11 questionnaires which were composed of large scale environmental problems(water and air pollution), and small scale environmental problems(food additives, GMO, endocrine disrupter) were performed with self-administered by university students(n=781) who made a application for liberal arts related to environmental subjects. According to the analysis the most student's consciousness of a point at issue of environmental problems(water pollution, air pollution, additives, GMO, endocrine disrupter), and practical attitudes(i.e., practical attendant at congregation and internet voting) were change statistically significant(p<0.01) after the education of a point at issue of environmental problems rather than before. Specially, the score for the item of the large scale problem of environmental issues(water pollution, air pollution) were decreased significantly(p<0.01), but the score for the small scale problems, such as food additives, GMO, endocrine disrupter were increased significantly(p<0.01) after the education of a point at issue of environmental problems(p<0.01). And among the students that participated, 97.7% responded that such a point at issues of environmental problem is needed at the university. With this educational improvements supports the states that the education of a point at issue of environmental problems were more essential, practical and needed to students at university rather than that of an existing instruction. Thus, further studies are required to develop the education of environmental issues at universities like STSE programme.
