The purpose of this study is to survey fundamental limitations and problems of sports event hosting from the critical point of view and to set future-oriented perspective. The reason and legitimacy for hosting sports event have come from pragmatism based on ideological logic behind politics. Thus, the flow of advanced studies was mostly limited to the category of efficiency. However, there is fundamental limitation in sports even hosting in terms of its financial expectation and efficiency. Critical approach will contribute to minimizing side effects caused from blind acceptance through awakening dispassionate and realistic judgment. In addition, rational selection of sports even hosting can be achieved through interconnection of sports culturism's directivity as an advanced sense of sports culture, integrated perspective that penetrates problems of growth and distribution and local governance as apolitical philosophy, and of course, through concentration of energy.

This study recent changes in urban thermal environment caused by climate change generate diverse problems such as urban heat island effects, heat wave, and drought. Under this condition, with the increased perception and expectation of the quality of life, the urban citizens' desire for outdoor activities is increasing. This study conducted the thermal environment analysis focusing on the urban ecological park used by many urban citizens, and also suggested the renovation measures for urban ecological park considering the thermal environment. As the research site, the ecologically-favorable Gildong Ecological Pak with diverse space composition was selected. The measuring items were measured and analyzed by dividing them into thermal environment index and thermal comfort index. In the results of analysis in each type of park space, the forest zone showed the most favorable result. Based on such results, total three kinds of renovation measures for urban ecological park considering the thermal environment were suggested. Through this, the urban ecology park renovation plans were presented in three ways. The results of this study are meaningful in that it can be used as a base material for creating an ecological park considering the thermal environment.

In this study, we intended to present a class design plan that combines safety education and software education, which are very important in the school field, but are considered necessary for change. In order to realize safety education centered on indirect experience, the 12th class plan was devised as a "Smart Safety Commuter Road Production Project" using a physical computing tool called Bitbrick. Based on the 12th city's class plan, qualitative research was conducted with interviews with a total of five teachers, showing both the effectiveness and problems of applying them to the class. The effectiveness is that unlike conventional delivery-type safety education, indirect experience-oriented safety education centered on real-life situations is possible, and it can be expected that procedural thinking skills can be developed along with stimulating interest. However, the problem has been shown that the process of implementing the direct situation can be challenging and that even activities can be more efficient than group activities.

The Body Appreciation Scale-2 (BAS-2) measures the extent to which individuals feel, accept, and respond to their own bodies in a positive manner. Given the research need to explore positive body image and its associations with various sociocultural factors and related consequences among individuals with various cultural backgrounds, several studies have established the psychometric properties and factor structures of the BAS-2 in different languages and samples with different characteristics. The current study investigated the psychometric properties and measurement invariance of a Korean version of the BAS-2 in an older Korean adult population (599 older Korean adults with the average age of 70 years). Data were collected using both online and offline (paper-based) survey questionnaires. The results of exploratory factor analyses and confirmatory factor analysis evidenced the unidimensional factor structure and measurement invariance of the Korean BAS-2 among older Korean men and women, after dropping item 1. Scalar invariance was supported across gender, and men and women did not significantly differ in observed mean scores of the Korean BAS-2. The results also supported good convergent validity and criterion validity. Incremental validity was demonstrated by predicting self-esteem over and above measures of age, BMI, subjective financial and health status, body esteem, and ageism. High internal reliability and test-retest reliability over a 2-week period were confirmed. Overall, the results of this study support the reliable use of a Korean BAS-2 to measure positive body image among older Koreans after excluding item 1.

Korea has become the highest nitrogen balance (228 kg/ha) among 34 OECD member countries, and has the stigma of being a 'Nutrient overload country' as of 2019. Accordingly, research on the derivation and utilization of nutrient balance indicators and the 'regional nutrient management system' are being promoted to improve Korea's nutrient balance. It is necessary to support these policies and studies, form a public consensus on improving the nutrient balance, and evaluate the function of the public benefit. This paper aims to estimate the public benefit value of improving the nutrient balance based on an analysis of consumers' willingness to pay and recognition of Korea's nutrient excess for 600 consumers nationwide. As results, 21.2% of the respondents said they were aware of excessive nutrients in Korea, and 76.7% of the respondents said they were aware of the need for nutrient management. The average amount of intention to pay for the improvement of three pollution (soil, water quality, and air) that can occur due to a nutrient overload was ￦2,321.1 for soil pollution improvement, ￦2,391.2 for water pollution improvement, and ￦2,377.9 for air pollution improvement. The average willingness to pay for the three pollution reduction was ￦6,002.3. These results are expected to be used to form a public consensus on the balance of payments and to establish measures to enhance public interest values in the future.

This study evaluates the AI digital competencies of teachers and presents a step-by-step framework for teacher's AI digital competencies that can be utilized in training. To do this, AI digital competencies were analyzed from the perspective of utilization and disposition, linked with the Technological Pedagogical Content Knowledge (TPACK) perspective. Then, as a precedent for step-by-step teacher AI digital competencies, the 3-step competency of the British Education and Training Foundation and the UNESCO ICT Teacher Competency Framework were presented. In this study, teacher's AI digital competencies were divided into three stages: entry, adaptation, and leadership, considering precedent research and domestic conditions. The initial entry stage passed the validity test in the second round of the Delphi survey, and the other two stages passed in the first round. The final entry stage is described as a stage where teachers understand AI digital but have difficulty implementing it, the adaptation stage is a level applied to standard curricula, and the leadership stage is a level where AI digital is applied in advanced courses and teachers serve as models for others. Through the overall AI digital competencies presented in this study, detailed competency development is possible, and it can be used as a reference material for developing evaluation items.

Along with the government's policy to encourage youth entrepreneurship, each university is making great efforts to promote entrepreneurship, and university entrepreneurship programs can be said to be the most important part of supporting and activating college students' entrepreneurship. In order to increase interest in and participation in entrepreneurship and entrepreneurship programs, it is necessary to take an in-depth look at students' perceptions of entrepreneurship and entrepreneurship programs. Therefore, this study used the effectiveness hierarchy model to explore the perceptions of college students at each stage and to identify bottleneck factors that hinder participation in entrepreneurship programs. For this purpose, focus group interviews and in-depth interviews were conducted using samples with different levels of interest and participation in entrepreneurship and entrepreneurship programs, and bottleneck factors at each stage of the effect hierarchy model were presented. The research results complement entrepreneurship research that was focused on quantitative research, and add important practical implications by approaching the study with a particular focus on local university cases.

This study used data from the 8th main survey of the National Old Age Security Panel to find out the effect of grandparents' capital that provides family care for grandchildren on life satisfaction. As a result of the study, the influence of capital of the study subjects on life satisfaction was 20.1%. Among the grandparents' capital, household gross income and health status had a significant positive (+) effect on life satisfaction. In other words, the higher the household gross income of grandparents who provide family care to grandchildren and the better the health status, the higher life satisfaction. On the other hand, caring time was found to have a negative (-) effect on life satisfaction, which means that the longer the time to care for grandchildren, the lower the life satisfaction of grandparents. These results suggest factors influencing grandparents' life satisfaction in these days when the likelihood of grandparents caring for grandchildren increases, and it was found that household gross income, health status, and caring time are major variables. Based on this, a plan was suggested to increase the life satisfaction of grandparents caring for grandchildren.
