In this study, the data from Korea National Health and Nutrition Examination Survey (KNHANES) was used to find out the relationship between breakfast patterns and suicide ideation of Koreans. This study used data from the 6th (2013-2015) and 7th (2016) of the Korea National Health and Nutrition Examination Survey (KNHANES) to analyze 8,508 participants, excluding those without information on breakfast frequency, age, gender, region, income levels, education levels, marital status, subjective health status, and drinking frequency for one year. The frequency of breakfast is classified as “5 to 7 times a week”, “3 to 4 times a week”, “1 to 2 times a week”, and “Rarely” (0 time a week). Whether breakfast accompanied by family members and non-family members was classified as “Yes” or “No” through a self-reported response to the question, “Did you eat with other people for most of the time when having breakfast during the past year?” When asked if he had seriously considered suicide in the past year, the answers were “Yes” or “No” through self-reported response and analyzed it through a chi-square test and multiple logistic regression. Analyses of associations after adjusting the correction parameters such as age, gender and income levels showed that the risk of suicide ideation was statistically significantly 1.41 times higher (OR: 1.41 95% CI 1.09-1.84) in the unaccompanied group, compared to those accompanied family and non-family members at breakfast. Also, the analysis of stratification by age showed that the risk of suicide was 1.45 times higher (OR: 1.45 95% CI 1.04-2.03) in the unaccompanied group, compared to those accompanied family and non-family members at breakfast. With the results of this study, it is necessary to seek ways to ensure that breakfast can be accompanied by family and non-family members, as well as efforts to reduce the rate of skipping breakfast.

The purpose of this study is to identify the potential for prevention of cardiovascular diseases when examinations of dyslipidemia are conducted for high-risk groups of cardiovascular diseases. A systematic literature review was carried out in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Group's systematic literature review reporting guidelines, and the search keyword was set to this : dyslipidemia and screening and high and risk and group and prevention and (CHD OR CAD OR CVD OR cardio heart disease OR coronary artery disease OR cardio vascular disease) As a result of the review, patients with diabetes and abnormal cholesterol levels were selected as high-risk groups, and the results of the examination of dyslipidemia in high-risk groups could reduce the possibility of cardiovascular disease. Hence, it is also believed that examination should be conducted in consideration of high-risk groups, and it is suggested that the cost effect of dyslipidemia examination for high-risk groups of cardiovascular diseases will continue.

The purpose of this study is to identify factors related to quality of life, focusing on oral health and nutritional status of vulnerable elderly people. A total of 368 middle and high-aged people aged 45 or older were selected as subjects of the study by conducting a full survey of vulnerable residents registered in the C-City Health and Living Center. From October 10 to December 20, 2019, the quality of writing, pronunciation, nutrition, subjective health, and quality of life were measured through a visit interview using structured questionnaires. There was a significant difference in the quality of life for the subjects (P = 0.003) between diabetes (2.93) and non-diabetic (3.09). The greater the discomfort of masticatory movement and pronunciation, the lower the quality of life (r = -0.239, r = -0.241), the higher the nutritional state, the higher the quality of life (r = 0.345). For diabetes, the factors affecting quality of life were subjective health (β= 0.376, P < 0.001), masticatory movement discomfort (β= -0.277, P = 0.049), nutritional status (β= 0.252, P = 0.005), and the modified explanation of the model was 29.1%. Overall, the quality of life of diabetics was an important factor in masticatory movement discomfort and nutrition. Therefore, it is suggested that a strategy is necessary to carry out proper oral health care in diabetes care.

Since 2015, Korea has been operating regional sports science centers in 10 cities across the country, and is pursuing a plan to systematically link athletes’ physical fitness through physical fitness measurements according to the athlete’s life cycle. For 243 elite athletes whose physical strength was measured by the Seoul Sports Science Center, the development direction of each sport type of the elite athletes in Seoul is analyzed through classification and grade. As a result of the study, in terms of basic physical strength, the difference in physical strength by sport type was significant in all items of muscle strength, muscular endurance, muscle power, cardiopulmonary endurance, agility, balance, and coordination except flexibility. As a result of analyzing the difference in the level of the physical strength factor according to the application of the fitness grade criteria for each sport type, the A type showed significantly higher differences in grip strength and back strength than the B and D types. It was significantly higher in sit-up than type A. Type B showed significantly higher physical endurance, muscle power, cardiopulmonary endurance, agility, coordination, and equilibrium compared to the A and D types, and D type showed higher physical strength level than the A type in cardiopulmonary endurance, agility, and balance. Based on the results of this study, it is considered necessary to compare the performance and physical strength of male high school students in Seoul and the characteristics of athletes by sport type to review the training method and improvement of the performance.

The purpose of this study is to investigate the sector-by-sector governance of Japan for support of transdisciplinary study, focusing on the cases of government sector, for-profit sector, and non-profit private sector. The research method of case study is applied to an example of the government sector, the Japan Society for the Promotion of Science’s ‘World Premier International Research Center Initiative (WPI)’, the ‘Beyond AI Institute’ by SoftBank Group Corp. as an example of the for-profit sector, along with the support of a research project by the Foundation for the Fusion of Science and Technology as an example of the non-profit private sector. Then these cases were analyzed particularly in terms of coherence, flexibility, and intensity. Using forms such as consortiums, which are irrespective of the existent university ranks, the advancement of support system for the commercialization of corporate-laboratory links and securing diversity of targets for convergence support and integrated management, it was concluded that the coherence, intensity, and flexibility of governance in support of transdisciplinary study could be increased as a result.

The purpose of this study is to explore the necessity and limitations of dementia exercise rehabilitation experts in the domestic dementia relief center. In recent years, the dementia relief center is expanding, and according to several previous studies, it is effective to apply exercise to the dementia risk group and early dementia patients. However, there are currently no experts in dementia exercise rehabilitation with in the domestic dementia relief center, and alternatives are being used to replace them. So we conducted research based on this. We conducted the study using two methods. The first is an analysis of 5 previous studies, and the second is to conduct interviews with three domestic dementia relief centers. First, the main contents of the 5 previous studies are the effect of exercise on dementia, the current status of the dementia relief center, and the necessity of a dementia exercise instructor in the dementia relief center. Based on this, interviews were conducted on three domestic dementia relief centers, and the contents of programs, instructors, certifications, participation rates, and facilities within the dementia relief center were found. In conclusion, we could know the necessity of a dementia exercise rehabilitation expert in the dementia relief center, and for this, it is necessary to establish a certificate of a dementia exercise rehabilitation specialist, a new professional training course, and a new professional educational institution.

The purpose of this study is to analyze the effects of the Tabata exercise program on male college students’ body composition, lower limb muscle strength, and cardiorespiratory functional capacity. For this study, eight male college students with an average age of 20.6 participated, and after applying the Tabata exercise program twice a week for 8 weeks, we did a comparative analysis by measuring body composition, lower limb muscle strength, endurance, and maximum oxygen uptake before and after the program. To analyze the differences between measurement values before and after the exercise, we used Wilcoxon’s signed rank test among nonparametric statistical methods. Among the changes in body composition, there was a significant increase in skeletal muscle mass, but the change in weight was not significant. The study exhibited significant statistical increase in the skeletal muscle mass from 31.9 kg to 32.8 kg, and basal metabolism, which increased from 1583 kcal to 1613 kcal. Weight and body fat increased, but no significant statistical change was detected. In muscular strength, the left flexor showed a significant statistical increase, and in muscular endurance, both the right flexor/extensor and left flexor/extensor displayed significant statistical increases. There was also an increase in maximum oxygen uptake, but not much critical difference. These results indicate that the Tabata exercise program, which involves many lower limb movements, enhanced improvements in muscle mass, muscular strength, and muscular endurance when performed for 8 weeks.
