The purpose of this study was to investigate the relationship between physical activity participation habits, physical fitness level, and academic performance among the Reserve Military Training Corps (ROTC). Participants in the current study were 71 ROTCs from J University. Physical activity participation was investigated using the Global Physical Activity Questionnaire (GPAQ), and the level of physical fitness was measured by health-related physical fitness evaluation. For academic performance, university grade data (GPA) was approved by the head of the relevant school district, and the data were collected with the consent of the participants, and each data was analyzed. The correlation between physical activity participation habits, physical fitness level, and GPA was analyzed, and GPA by physical fitness level were compared. This study found that there was no statistically significant correlation between physical activity participation and academic performance. Otherwise, there was a statistically significant correlation between major subjects and total physical fitness score, cardiorespiratory fitness, muscular endurance, flexibility, and body composition. By the level of physical fitness, the ROTCs in the high-physical fitness group showed statistically significantly higher academic performance than the ROTCs in the low-physical fitness group. In addition, low level of physical fitness ROTC group was lower than the other. In conclusion, ROTCs with a high physical fitness level had a positive effect on improving learning ability compared to those who did not. By recommending an autonomous but systematic exercise training program, it is suggested to improve the physical strength of ROTCs and to cultivate excellent future military officers.

The purpose of this study was to examine the effects of a physical activity program on body composition, depression and risk factors of dementia in elderly women. Subjects were 40 women aged 65~75 years, classified into two groups (experiment group 20, control group 20). The factors measured in this study were body composition (weight, percent body fat, body mass index, body fluid), depression (BDI score) and risk factors of dementia (K-MMSE, LDL-C, HDL-C, insulin, ${\beta}$-amyloid, DHEAs) at 12 and 24 weeks before and after the program. Subjects of experiment group participated in a 24 week physical activity program (45~60 min, 3~4 day per weeks). Data were analyzed by repeated ANOVA method of SPSS, with accepting levels for all significances above ${\alpha}$=0.05. The results of this study were as follows. In body composition, the experiment group showed significant differences in the weight, percent body fat and body mass index compared to the control group. In depression score, the experiment group showed no significant differences regarding BDI score level compared to the control group. In risk factors for dementia, the experiment group showed significant differences in levels of K-MMSE, LDL-C, HDL-C, insulin, ${\beta}$-amyloid, and DHEAs compared to the control group. This study showed that a 24 week physical activity program had positive effects on almost all of the factors evaluated in elderly women, and that elderly women who did not participate in the program experiences no such positive effects. Therefore, regular participation in a physical activity program could be advocated as one strategy to enhance body fat, depression, and risk factors of dementia and may result in improving risk for diseases of age in elderly women.

Despite a growing trend in elder mistreatment, research about the problem and its effects on the victims has been sparse. Notably missing are the perspectives of older adults themselves, whose perceptions and responses to elder mistreatment are greatly affected by social and cultural context. The purpose of this study is to examine factors associated with older persons' perceptions of elder mistreatment and subsequent help-seeking behaviors. Six hypothetical scenarios featuring elders were the basis of interviews with 124 older persons, drawn by a quota sampling strategy. Findings indicated that older persons perceived situations of physical abuse (87.9%), financial abuse (86.3%), and psychological abuse (66.1%) to be elder mistreatment, yet respondents showed less sensitivity to elder mistreatment that took the form of physical mistreatment within a couple (47.6%), neglect (40.3%), and self-neglect (16.9%). Certain scenarios yielded less intention to seek help: namely, physical mistreatment within a couple, neglect, and self-neglect. Older persons' personal characteristics, social factors, and cultural factors exerted significant influence on both perception and help-seeking behavior. Perception was identified as a key factor that significantly influenced help-seeking behavior. Findings point to awareness of cultural and social context for success in elder mistreatment prevention, intervention, and policy design for this population.

Urban Green space takes charge of the important role for the physical activity and promotion of health to the residents. Therefore, this study is trying to examine the relationship between the various characteristics of green space and green space usage for physical activity and health promotion. A questionnaire survey was conducted to obtain the information about patterns of green space usage and perceived neighborhood environments for the residents living in Changwon-si, Gyeongsangnam-do(n=541). Geographic Information System(GIS) was used to construct spatial data about green space accessibility and physical neighborhood environments. A Multiple Linear Regression model was used to examine the association between the characteristics of green space and physical activity, perceived health status and BMI(Body Mass Index). The study results revealed that the residents' physical activities are positively and directly influenced by the number of available public parks and green spaces in the vicinity(${\leq}200m$). The frequency at which residents witness others exercising nearby or the perceived abundance of low-cost gym facilities also factor as positive influences. The closer to the park, the higher the number of parks and area of green spaces, the more comfortable the walk thereto and the denser the neighboring residential area distribution, the perceived health level was found to be the more positively influenced. Further, it was verified that BMI is correlated with the number of public parks and green spaces within 400 m of the resident's home as well as the safety of walkways, the density of neighboring residential areas, the ratio of road, and the density of crosswalk. The significant multiple regression models between the characteristics of green spaces and physical activities and perceived health level were extracted within the significance level of 10%. This study will contribute to provide better understanding the ways in which green space and neighborhood characteristics are associated with physical activity and health. The result of this research will be available in the landscape architecture plan aimed at improving the use of green space for physical activity and reducing obesity.

Purpose: The purpose of this study was to explore the relationship between milk intake and prevalence rates of chronic diseases using KNHANES data, and the significance of the relationship was tested based on meditators, socioeconomic status (income, education), dietary behaviors (smoking, alcohol drinking, breakfast, and eating out), and physical activity (walking, medium, and high). Methods: Using the 5th and 6th survey data of KNHANES, milk intake rates and presence of seven chronic diseases were summarized and analyzed by ANOVA for two groups of adult men and women as follows: hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, abdominal obesity, obesity, and metabolic syndrome. The dependent variables for the presence of seven chronic diseases regressed with socioeconomic, dietary behavior, and physical activity variables according to Logistic models. The dependent variables for milk intake using predictor variables of socioeconomic, dietary behaviors and physical activity were analyzed according to Logistic models. Finally, the significant socioeconomic, dietary behavior, and physical activity variables in the above model along with milk intake as a control variable or mediator variable regressed with significant chronic diseases according to Logistic models. Results: Milk intake, socioeconomic status, dietary behaviors, and physical activity were significantly different among the two groups of adult men and women, which were also critical factors to the prevalence of chronic diseases. The dependent variable for prevalence of chronic diseases regressed with significant factors of socioeconomic status, dietary behavior, and physical activity variables according to chronic diseases using the control or mediator variable of milk intake and summarized as follows: For adult men, milk intake controlled the education effect on diabetes partly, alcohol on hypertension and hypertriglyceridemia, low HDL-cholesterol, metabolic syndrome, breakfast on metabolic syndrome, eating out on obesity, and medium physical activity on hypertriglyceridemia. For adult women, household income on hypertriglyceridemia, diabetes, abdominal obesity, education level on hypertension, alcohol drinking, eating out, and walking activity on abdominal obesity, alcohol, breakfast, eating out, walking activity on low HDL-cholesterol, and medium physical activity on hypertriglyceridemia and low HDL-cholesterol were partly controlled by milk intake. Other significant socioeconomic status, dietary behavior, and physical activity variables related to prevalence of chronic diseases were fully controlled or mediated by milk intake. Conclusion: This study shows that milk intake (daily more than 200 g) prevents chronic diseases such as hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, obesity, abdominal obesity, and metabolic syndrome.

The purpose of this study was to investigate predictors and mediating effects of physical activity and nourishment regulation on well-being among young and middle aged patients on DM medication and to compare between those with non-pharmacological treatment and those without. Data were obtained from 2017 community health survey including 1,480 DM patients with oral medication in the age between 20 and 49. Using SPSS 25.0 and AMOS 25.0, path analysis was performed to explore the association between personal factors (socio-economic status, health habit, eating habit and compliance of health examination) and well-being, along with mediating effects of physical activity. Results demonstrated the different mediating role of physical activity. In medication only group, there was no direct effect of physical activity and no indirect effect of personal factors. Direct effect of physical activity and indirect effects of predictors were found in those with non-pharmacological treatment group. When developing strategies to enhance well-being of young and middle aged diabetic patients, proper reflection of their age specific traits and disease management capability are essential.
