The purpose of this study is to identify physical activity levels of the basic livelihood security recipients elderly women, to investigate relation between cardiovascular disease risk factors and sacrcopenia based on the levels, and to develop physical activity programs for healthy life of the elderly. The subjects of this study were 134 old females with $71{\pm}6.67$ years old who used senior centers in K-gu. The authors used the International Physical Activity Questionnaire for investigating the physical activity levels of the elderly, measuring their physical activity levels for seven days on average and classifying them into two groups, the Low Physical Activity (n=77) and the Moderate Physical Activity (n=57) groups based on the levels. Blood pressure, waist measurement, TC, HDL-C, LDL-C, TG, Glucose, and atherogenic index (AI) were measured as the cardiovascular disease risk factors; percent body fat, appendicular skeletal muscle mass, total muscle mass, and skeletal muscle index were measured as factors related to sarcopenia. Independent samples t-Test was conducted to analyze differences on the two groups based on the physical activity levels, with ${\alpha}=.05$ the as significance level. According to the results, HDL (p=.017) were higher and AI (p=.007) was lower; percent body fat (p=.008) was lower, and ASM (p=.000), total muscle mass (p=.000), and SMI (p=.001) were higher. In conclusion, moderate intensity physical activities rather than low intensity ones may have positive effects on the cardiovascular disease risk factors and sarcopenia levels, and participation in regular physical activities with at least moderate intensity by various methods may be needed for prevention of illness and healthy life of the elderly.

Objectives: The purpose of this study is to analyze each country's infectious disease response capacities and, based on this, find areas for improvement in Korea's infectious disease management response. Methods: First, the capacity to respond to the COVID-19 infectious disease was analyzed by country using the SPAR scores of 96 countries around the world released by WHO in 2022. Second, we analyzed each country's specific COVID-19 quarantine performance using Our World in Data and the Global Health Security Index (GHSI). Results: First, the quarantine intensity index on January 24, 2021 was the highest in the Southeast Asia branch at 67.6, which had strong quarantine measures, and the lowest at 44.5 in the Africa branch. As of December 31, 2022, the quarantine intensity index in Europe was significantly lowered to 11.6. Second, the factor that influenced the SPAR indicator on the total number of patients per million population was national laboratory (C4), p=.027, and the factor that influenced the total number of deaths per million population was infection prevention and control (C9), p=.005., Risk Communication and Community Participation (C10) p=.040. The influential factor on GDP per capita was infection prevention and control (C9) p=.009, and the influential factor on GHSI was infection prevention and control (C9) p=.002. Conclusion: The research findings indicate that it was difficult to find a correlation between the SPAR, which is each country's self-assessment of their infectious disease capacities, and the number of COVID-19 cases or the intensity of pandemic responses. However, mortality rates, as well as factors such as the Global Health Security Index (GHSI) and national income, appear to be somewhat influenced. For future improvements in infectious disease management and response in our country, it is necessary to develop pandemic strategies that can reduce socio-economic costs based on more scientific and reliable data like JEE or GHSI, especially in preparation for potential unknown emerging infectious diseases. Based on this, proactive decision-making led by a control tower of experts and effective health communication are also required to respond to public health crises at a national level.

The aim of this study was to survey the effects of planned exercise over the age of 65 in male and female with regard to their self-efficacy, depression, and life satisfaction, based on the literatures of 14 master and doctoral dissertations published between 2004 and 2014. The subjects with program exercise habit were chosen considering the generalization of the physical characteristics of elderly subjects. The exercise duration was 50 minutes for 3 times a week for 12 to 24 weeks. Exercise intensity was an optimal aerobic exercise plan that the subjects themselves could perform. The average effect size of self-efficacy was 0.793 (26.1% increased), depression was -0.91(31.9% decreased), and life satisfaction was 1.506 (43.4% increased). These indicate that post-exercise psychological variables had a positive effect on self-efficacy and life satisfaction by lowering depression after regular exercise. Therefore, it is necessary to increase regular exercise participation and to provide sustainable scientific information for the aged and healthy living of the elderly.

In this study, we empirically investigated the antecedents of crowdfunding success in the arts and cultural field using the case of Tumblbug in Korea. We collected data on 494 projects listed on Tumblebug in the arts and culture category that includes feature film, documentary, short film, animation, and Web series, as of June 2018. We analyzed the factors associated with the final amount raised via crowdfunding on Tumblbug using the hierarchical regression method. We find that the social capital accumulated by a focal entrepreneur (i.e., the proposer/designer of a focal project) through prior participation in other related projects and social communication activities carried out during the funding period, respectively, have positive effects on the final amount raised. More interestingly, we also find that the intensity of social communication plays a central role in the funding success of arts and culture-related projects by supplementing the lack of the entrepreneur's social capital and the reward features including a given project.

Based on sports known to reduce adolescents' smartphone addiction, this study aims to identify the structural causal relationship between sport commitment and smartphone addiction. First of all, based on prior studies, it was intended to show that adolescents' sport commitment is effective in reducing smartphone addiction through social support and ego-resilience, and that such causal relationships vary significantly depending on gender. To this end, a survey of 605 middle and high school students was conducted, and the structural relationship between the four established latent variables was analyzed by analyzing the structural equation model using the SPSS 25.0 and AMOS 23.0 programs. According to the analysis, adolescents' sport commitment was found to have an adverse effect on smartphone addiction, and social support and ego-resilience in the relationship between the two variables were found to have a mediated effect. In addition, these results showed significant differences in gender. This study expanded the field of smartphone addiction and sports convergence study by revealing the relationship between sport commitment as psychological recognition variable and addiction Unlike previous studies using a participation time, duration, and intensity, and suggested that structural relationships with personal characteristic variables and gender-specific approaches are important. Through this, it is meaningful that it provided basic data for in-depth convergence study in the smartphone addiction and development of gender-specific programs.

Objective : The aim of this study was to identify subgroups of older adults with respect to their lifestyle patterns and examine the characteristics of each subgroup in order to provide a basic evidence for improving the health and quality of life. Methods : This cross-sectional study was conducted in South Korea. Community-dwelling older adults (n=184) above the age of 65 years were surveyed from April 2019 to May 2019. This study used latent profile analysis to examine the subgroups. Chi-squared (χ²) and multinomial logistic regression measures were then used to analyze individual characteristics and influencing factors. Results : The pattern of physical activity which is one of the lifestyle domains in elderly was categorized into three types: 'passive exercise type (31.1%)', 'low intensity exercise type (54.5%)', and 'balanced exercise type(14.5%)'. Activity participation was divided into three patterns: 'inactive type (12%)', 'self-management type (61%)', and 'balanced activity participation type (27%)'. In terms of nutrition, there were only two groups: 'overall malnutrition type (13.5%)' and 'balanced nutrition type (86.5%)'. Furthermore, as a result of the multinomial logistic regression analysis to understand the effects of lifestyle types on the health and quality of life of the elderly, it was confirmed that the health and quality of life were higher in those following an active and balanced lifestyle. In addition, gender, education level and residential area were analyzed as predictive factors. Conclusion : The health and quality of life of the elderly can be improved when they have balanced lifestyle. Therefore, an empirical and policy intervention strategy should be developed and implemented to enhance the health and quality of life of the elderly.

This study was conducted to test the effects of participation in 12-week program of boxing aerobics by obese middle-aged women on their body composition, blood constituents, and vascular compliance The samples are the middle-aged women in their forties or more, who has 30% or more body fat percentage, but has no medical history in cardiovascular disorders or metabolic diseases. The samples are divided into 8 of exercising group, and 8 of control group by random assignment. The intensity of boxing aerobics was HRmax 50% for the initial 4 weeks, HRmax 60% for the 5th to 8th week, and HRmax 70% for the 9th to 12th week. Each session took 60 minutes. The result is as follows. First, as a result of participating in the boxing aerobics program, body weight, body fat percentage, and muscle showed significant differences depending on the measuring period and the interacting term of the group and measuring period(p<.001), and the result of t-test on the sample matched to each group's measuring time also showed the significant increase or decrease in the exercising group(p<.001). Second, as a result of participating in the boxing aerobics program, the exercising group's TC, TG, HDL-C, and LDL-C, all showed significant differences in accordance with each group, measuring time, and the interaction term between groups and measuring time(p<.01, p<.001), and the result of t-test on each group's samples matched to the measuring time also shows significant increase or decrease in the exercising group(p<.01). Third, as a result of participating in the boxing aerobics programs, the vascular compliance of right hand, left hand, right hand, and left hand showed significant differences in accordance with each group, measuring time, and the interacting term between the measuring time and the group(p<.001), the t-test results of the samples matched to the each group's measuring time also showed significant differences in the exercising group(p<.001). To summarize the results above, it is suggested that the 12-week boxing aerobics program can improve body composition, blood constituents, and the blood circulation, which may prevent or enhance relevant diseases such as cardiovascular disorders.
