Like Alzheimer's disease, Parkinson's Disease(PD) is one of the most common neurodegenerative brain disorders. PD results from the deterioration of dopaminergic neurons in the brain region called the substantia nigra. Currently there is no cure for PD, but diagnosing in its early stage is important to provide treatments for relieving the symptoms and maintaining quality of life. Unlike many diagnosis methods of PD which use a single biomarker, we developed a diagnosis method that uses both biochemical biomarkers and imaging biomarkers. Our method uses ${\alpha}$-synuclein protein levels in the cerebrospinal fluid and diffusion tensor images(DTI). It achieved an accuracy over 91.3% in the 10-fold cross validation, and the best accuracy of 72% in an independent testing, which suggests a possibility for early detection of PD. We also analyzed the characteristics of the brain fiber pathways of Parkinson's disease patients and normal elderly people.

The purpose of this study is to investigate the moderating effect of home-based welfare facilities for older adults on the associations between the activities of daily living (ADL) / instrumental activities of daily living (IADL) and the depressive symptoms among Koreans in later life. Multilevel analysis was conducted with Korean Longitudinal Study of Aging 5th data and the public report about welfare facilities from Ministry of Health and Welfare in Korea. Samples were 4,139 older adults over 65 years old. The dependent variable was depressive symptoms, and individual level independent variables were ADL and IADL. The ratio of home-based welfare facilities out of 10,000 older adults in each city and province was the moderator. As a result, the effects of ADL on depressive symptoms vary according to the proportion of elderly welfare facilities out of the old population in the community. In specific, the older adults who live in the place where the elderly welfare facility rate was higher were less affected by ADL. Also, the more IADL people had, the more depressive symptoms they had. However, the interaction effect between IADL and the proportion of home-based welfare facilities was not significant. It suggests that delivering welfare services helping ADL through the home-based welfare facilities may be useful for decreasing depressive symptoms. Moreover, considering the proportion of facilities and older population will be helpful to make the welfare facilities efficiently work.

PURPOSE: The study compared the satisfaction of the exercise program in a face-to-face and non-face-to-face manner with the same exercise program. METHODS: This study was conducted through convenience sampling for 57 seniors over 65 years of age. After conducting 30 minutes of the same exercise program face-to-face on the first visit and non-face-to-face on the second visit, a satisfaction survey was conducted. The survey data were processed statistically using SPSS 26.0 (SPSS Inc, IBM, USA). An independent t-test was used to compare the type of exercise program. The Spearman's Rank Correlation was conducted to correlate the satisfaction between cognitive function and education level. RESULTS: The overall satisfaction with the face-to-face program was higher than the non-face-to-face exercise programs. All three satisfaction items in face-to-face exercise programs were higher than in non-face-to-face exercise programs (p < .05). The main source of dissatisfaction in the case of face-to-face exercise programs was having a good relationship with people for face-to-face and a 'lack of communication' in the case of non-face-to-face. CONCLUSION: The elderly showed higher satisfaction in face-to-face exercise than in non-face-to-face exercise. This study is significant in that accurate satisfaction comparison was possible by conducting the same exercise program on the same subject for a relatively short time, and through this, the development of an exercise program was suggested.

The purpose of this study is to investigate the factors affecting the intention to use healing farming by setting aged readiness, rural healing supply condition, and rural healing service as independent variables. This study has been started based on the idea that it is necessary to provide healing service through healing agriculture to the rapidly increasing elderly people and urban people who need mental rest. Therefore, the purpose of this study is to find out the various factors influencing intention to use healing agriculture through empirical analysis. Second, we want to examine whether the variables influenced the intention to use more. Third, based on the results of these tests, we suggest the policy for activation of healing agriculture by examining the factors necessary for the promotion of physical and mental health of the elderly in the aging society and the revitalization of healing agriculture for the mental healing of the urban people. For this study, a questionnaire survey was conducted for men and women over 30 years old, and the final 356 copies were analyzed. The validity of the research hypothesis was verified by linear regression analysis. The results of the analysis are as follows. First, the physical preparation, emotional preparation, and economic preparation of aged care preparations were found to have a significant effect on intention to use. Second, natural landscape, accessibility, and stability of rural healing supply conditions were found to have a significant effect on intention to use. But economics and expertise were dismissed. Third, crop cultivation, animal medication and healing facilities of rural healing service were proved to have significant influence on intention to use. In order to increase the utilization of healing agriculture, it is necessary for the consumer to be well prepared for aging. In rural healing supply conditions, accessibility and safety should be provided for healing facilities in rural healing services.And to increase the intention to use it.

Unlike the semi-public system of city buses, Seoul's townbus are operated on a private operating system, which is poor condition to the changes in the environment. Sales decreased due to a decrease in the number of passengers due to COVID-19 and a demand for conversion due to the advent of competitive transportation methods, and the financial support of Seoul Metropolitan Government is continuously increasing. In this study, to analyze the characteristics of townbus operated by a private operating system, the townbus sales and surplus companies were analyzed by what factors were affected. For the analysis data, townbus financial statements of Seoul in 2018 were used, and townbus sales and surplus companies were applied as dependent variables, and townbus operation system, satisfaction survey, humanities and social variables, and subway and public bicycle characteristics were applied as independent variables. As a result of the analysis, the sales is affected by operating hours per vehicle, in-vehicle safety, the number of households, the number of elderly people, and public bicycle variables, and surplus companies are affected by in-vehicle safety, reliability, and public bicycle variables. In particular, public bicycles, a competitive means of transportation, had an impact on industry sales, and the townbus business environment is expected to become more difficult as time goes by. The industry is seeking self-rescue measures, and Seoul is required to strengthen financial support so that townbus can operate stably.

A monosomal karyotype (MK), defined as ${\geq}2$ autosomal monosomies or a single monosomy in the presence of additional structural abnormalities, was recently identified as an independent prognostic factor conveying an extremely poor prognosis in patients with acute myeloid leukemia (AML). In the present study, after excluding patients with t(15;17), t(8;21), inv(16) and normal karyotypes, 324 AML patients with cytogenetic abnormalities were the main subject of analysis. The incidences of MK were 13% in patients aged 15 to 60 years and 18% in those between 15 and 88 years old. MK was much more prevalent among elderly patients (p < 0.001) and was significantly associated with the presence of -7, -5, del(5q), abn12p, abn17p, -18 or 18q-, -20 or 20q- and CK (for all p < 0.001 except for abn12p p=0.009), and +8 or +8q was less frequent in MK+ AML(p=0.007). No correlation was noted between monosomal karyotype and FAB subtype (p > 0.05); MK remained significantly associated with worse overall survival among patients with complex karyotype (p=0.032); A single autosomal monosomy contributed an additional negative effect in OS of patients with structural cytogenetic abnormalities (P=0.008). This report presents the prevalence, feature and prognostic impact of MK among a large series of Chinese AML patients from a single center for the first time.

This study aims to review the trends of the population outflows in the metropolitan area of Busan and to investigate the factors that affect population out-migration to the Seoul metropolitan area. The following variables are considered for analysis: traditional population movement variables and quality of life variables, such as population, society, employment, housing, culture, safety, medical care, greenery, education, and childcare. The 'domestic population movement data', provided by the MDIS of the National Statistical Office, was used for this research. Out of the total of 57 million population movement data in the period 2012 - 2017, population outmigration from Busan to the Seoul metropolitan area was extracted. Independent variables were drawn from public data sources in accordance with the temporal and spatial settings of the study. The multiple linear regression model was specified based on the dataset, and the fit of the model was measured by the p-value, and the values of Adjusted R2, Durbin-Watson analysis, and F-statistics. The results of the analysis showed that the variables that have a significant effect on population movement from Busan to the Seoul metropolitan area were as follows: 'single-person households', 'the elderly population', 'the total birth rate', 'the number of companies', 'the number of employees', 'the housing sales price index', 'cultural facilities', and 'the number of students per teacher'. More positive (+) influences of the population out-movement were observed in areas with higher numbers of single-person households, lowers proportions of the elderly, lower numbers of businesses, higher numbers of employees, higher numbers of housing sales, lower numbers of cultural facilities, and lower numbers of students. The findings suggest that policies should enhance the environments such as quality jobs, culture, and welfare that can retain young people within Busan. Improvements in the quality of life and job creation are critical factors that can mitigate the outflows of the Busan residents to the Seoul metropolitan area.

Objectives: This study is to investigate the prevalence and related factors of metabolic syndrome among Korean adults aged 20 years and above. Methods: From the database of the $5^{th}$ Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2010, data of 5,670 adults who responded to all the questionnaires of health interview and had metabolic syndrome in the health examination were included in this analysis. SAS 9.2 was used for statistical analysis with complex sample survey modules and commands. Results: The prevalence rate of metabolic syndrome based on the criteria proposed by International Diabetes Federation (IDF) was 18.8%. The prevalence of metabolic syndrome in each group was: 20.7% of women, 43.1% among elderly over 70 years old, 40.6% of the divorced or the separated, 27.6% of recipients of economic support from the government, 23.6% of people who had alcohol dependency problem, and 43.7% of overweight or obese adults. Independent risk factors based on the multiple logistic regression analysis revealed that prevalence of metabolic syndrome was associated with female (odds ratio 1.59 [95% confidence interval 1.20-2.11]), age (50s 3.95 [2.11-7.37], 60s 5.62 [2.98-10.61], 70s 10.56 [5.25-21.25]), high school education (0.52 [0.37-0.74]), clerk occupation (2.14 [1.27-3.60]), divorced marital status (1.72 [1.15-2.59]), alcohol dependency (1.86 [1.16-2.98]), higher BMI (14.08 [10.60-18.70]). Conclusions: The metabolic syndrome is prevalent among Korean adult population according to IDF criteria. Several demographic characteristics and potentially modifiable factors are associated with metabolic syndrome. Identification of this high-risk group and management of these modifiable factors are warranted to reduce the prevalence of metabolic syndrome.
