The purpose of this study is to investigate the relative influence of diet and physical activity on obesity. The subjects were 155 adults aged 35-52 years from 24 neighborhood committees in 4 urban districts of Beijing (male : 78, female : 77). They were divided into normal weight, overweight and obese groups according to their BMI. The general information of the subjects was collected by interview-administered questionnaire. Dietary intake was obtained by three-day(two weekdays and one weekend day) food weighted method, physical activity was assessed by a validated combination of data obtained from activity monitors, bicycling information and activity records. There were no significant differences of age, gender, height, educational, family economic level, smoking and drinking between different groups. The proportion of flour intake was higher in obese group compared to normal weight and overweight groups, and that of vegetables is lower in obese group. The physical activity (PAL) was not significantly different between two groups of the normal, overweight and obese groups. After the adjustment for confounding factors using logistic regression model, we found that the proportion of flour intake was positively associated with obesity, while the proportion of vegetable intake was inversely associated with obesity. It is concluded that dietary patterns were associated with obesity and diets composed of more vegetables and less staple combined with physical activities could contribute to obesity prevention.

This study aims to analysis the migration tendency according to the residents' lifestyle in a large residential estate development. The lifestyle of residents in the suburban area who make their life by agriculture is different from that in the inner city. It may affect on the migration tendencies of the residents. Sin-seo residential land development district is located in the suburban of Daegu is chosen as the case study. This study examines the characteristics of residents' lifestyle and their migration tendency and analyzes the correlation between them. According to the results, the appropriate countermeasures to support the migrants are drawn as follows; First, the people who want to resettle and continue to do farming in the same place should be compensated with housing lands near their farmlands. Second, the residents who want to carry on a small business should be provided with the housing land near to the commercial zones. Third, the size of the new neighborhood unit should be enough to preserve the existing social structure as the social relationship among the neighbors is one of the most important factors in rural communities. Fourth, the high level of housing attachment of the residents needs to remain by maintaining the names of villages and roads of the neighborhoods. It is required to consider the lifestyle of residents and active communities when large residential land development district is planed in the suburban.

This study performed factor analysis for 21 independent variables related to the effect of illumination and suggested the effect by multiple regression analysis on the relationship between the effect of illumination and the satisfaction of use of a dependent variable to find the effect of illumination in urban parks at night and the effect of illumination on the satisfaction of use. The results of this study are as follows; 1) Of the 21 independent variables used to study the effect of illumination in urban parks at night, the impact on safety and possibility of crime was highly. The effects of illumination by factor analysis were abstracted as effects of removing anxiety, securing safety, increasing use. 2) As a result of multiple regression analysis, independent variables influencing satisfaction of use in urban park were proved as effects of removing anxiety, securing safety, increasing identity, preparing atmosphere and increasing use. Also, the effect of securing safety was the most important factor; it showed a level of importance 2 times higher than the effect of removing anxiety, and 7.7 times higher than the effect of preparing atmosphere in relative contribution of the effect of illumination to satisfaction of use. 3) Of the effects of illumination influencing satisfaction of use in urban parks, the effect of securing safety and the effect of increasing visibility were more significant than the effects of removing anxiety, preparing atmosphere and increasing use. This fact means that personal safety an the identity of persons or facilities in the space of use should be considered with priority in planning or designing illumination. Also, it implies hat, for night use in urban parks, lightness of the space is required for general safety of use at parks, and proper illuminance on the activity in the space of use should be required. The subject parks of this study are 8 urban neighborhood parks. The model on the effect of illumination and the satisfaction of use depends on characteristics and conditions of location of he park and user class, so the subject parks and persons should be varied, and the difference by sex or ages should be suggested.

The purpose of this study is to develop a simulation model of rural road path for infrastructure of green-tourism and public service in rural areas. This study makes an objective function for moving cost minimization considering car travel time according to road characteristics, which can route the optimal shortest road paths between the center places and all rear villages, based on GIS coverages of road-village network for connecting between center places and rural villages as input data of the model. In order to verify the model algorithm, a homogeneous hexagonal network, assuming distribution of villages with same population density and equal distance between neighborhood villages on a level plane area, was tested to simulate the optimal paths between the selected center nodes and the other rear nodes, so that the test showed reasonable shortest paths and road intensity defined in this study. The model was also applied to the actual rural area, Ucheon-myun, which is located on Hoengsung-gun, Kangwon-do, with 72 rural villages, a center village (Uhang, 1st center place) in the area, a county conte. (Hoengsung-eup, 2nd center place), and a city (Wonju, 3rd center place), as upper settlement system. The three kinds of conte. place, Uhang, Hoengsung-eup, and Wonju, were considered as center places of three scenarios to simulate the optimal shortest paths between the centers and rural villages, respectively. The simulation results on the road-village network with road information about pavement and width of road show that several spans having high intensity of road are more important that the others, while some road spans have low intensity of road.

Nowadays, interest in health care is increasing due to Coronavirus (COVID-19), and a lot of people are doing home training as there are more difficulties in using fitness centers and public facilities that are used together. In this paper, we propose a personalized exercise recommendation algorithm using personalized propensity information to provide more accurate and meaningful exercise recommendation to home training users. Thus, we classify the data according to the criteria for obesity with a k-nearest neighbor algorithm using personal information that can represent individuals, such as eating habits information and physical conditions. Furthermore, we differentiate the exercise dataset by the level of exercise activities. Based on the neighborhood information of each dataset, we provide personalized exercise recommendations to users through a dimensionality reduction algorithm (SVD) among model-based collaborative filtering methods. Therefore, we can solve the problem of data sparsity and scalability of memory-based collaborative filtering recommendation techniques and we verify the accuracy and performance of the proposed algorithms.

Purpose: This study aimed to investigate the association of social participation and depressive symptoms with health-related quality of life (HRQoL) among older adults living in urban and rural areas. Methods: This secondary, cross-sectional study was conducted with a total of 66,765 adults aged ≥65 years (urban-26,485 and rural-40,280) who participated in the household and individual surveys of the Korea Community Health Survey 2019. Data on the main study variables including social participation, depressive symptoms, and HRQoL were collected from August 16 to October 31, 2019. Multiple linear regression was used to identify the factors affecting HRQoL in urban and rural older adults. Results: The proportion of social participation (χ²=354.69, p<.001) and the level of HRQoL (χ²=12.06, p<.001) were significantly higher in older adults living in urban area than those in rural area. However, there was no significant difference in depressive symptoms between older adults living in urban and rural areas. Multiple linear regression analysis showed that social participation and depressive symptoms were significant predictors of HRQoL in both urban and rural older adults. Conclusion: Our main finding highlights that active participation in social activities and management of depressive symptoms in older adults regardless of living arrangements are crucial to improve HRQoL in later life. Interventions to increase social participation include early assessment of depressive symptoms in the community to promote HRQoL. More longitudinal studies are needed to identify the factors associated with HRQoL between older adults living in urban and rural areas while considering neighborhood environment and living arrangements.
