The purpose of this study is to examine demographic characteristics, psychological characteristics and patterns of supportive relationships with their children that affect the successful lives of the elderly. A survey was conducted of 410 people aged between 65 and 85, and 405 samples were used for the analysis. First, the supportive relation between the elderly and their children was categorized into four groups depending on the total amount and direction of support. The four groups consisted of the elderly who exchanged little or no support, those who only received support from their children, those who only gave support, and those who both gave and received support. Second, the more the elderly exchanged support and gave emotional support to their children, the better the chance that the elderly would lead a successful life in later years. Third, subjective health conditions most significantly affected the successful lives of the elderly who exchanged little or no support. The level of education was most significant for the elderly who only received support. The level of housing satisfaction mostly affected the elderly who only gave support. Mutual support primarily affected the elderly who both gave and received. Thus, we should provide health programs for the elderly who exchange little or no support to encourage a healthier lifestyle. In addition, opportunities for continuing education should be provided for the elderly who only receive support to make up any deficiency in education. Because spouses are mostly affected for those elderly who exchange little or no support and the elderly who only receive support, we should provide educational programs about how to be better lifetime companions to each other and also provide medical and in-home care for the remaining spouse even after the other partner is gone. Because housing satisfaction greatly affects the elderly who only give support, improvements in the residential environment are essential. Since the level of mutual support is crucial to the elderly who both give and receive support, programs on the development of human resources are needed for the elderly to interact dynamically and intimately with their children.

The position of the bridged tap is determined by that of the outlet in most modern apartments, since most of the indoor wiring utilizes the bus wiring structure when deploying the indoor communication line. These bridged taps deteriorate transmission performance in the specific frequency at the time of high-speed multimedia communication, which uses a high frequency bandwidth, since the duality of return loss worsens and line attenuation increases rapidly. As a result, analysis on this phenomenon is required. In this study, the test model is created by modeling the intercommunication facility of the apartment that is the most representative residential house type, and by understanding the structure and the environment of the indoor wiring. Also, how the bridge tap affects performance is analyzed when the VDSL service is provided, so that problems of intercommunication lines can be identified and methods for improving the proper intercommunication line can be suggested, which is suitable for accommodating high-speed multimedia service of the future.

In order to analysis of the water pollution of the Anyang stream(one of the biggest branch streams of the Han River) and its main tributaries, the geological and topographical and rainfall features in its basin were investigated. To do this, the water samples were collected 23 points of the upper, mid and down of Anyang stream and its tributaries and were analyzed based on the chemical methods, Korean Biotic Index(KBI) and Saprobien systems. The Anyang stream basin has a characteristic of topographical torrential heavy rainfall like a typical rainfall feature in Korea. The concentration and the outflow rate of rainfall is very different in seasonal, and water pollution in dry season is especially severe. After 1997, although the water quality status of stream has been improved gradually, the concentration of T-N and SS at the upstream is increased due to the deficiency of facility used for collecting wastewater released from industrial factories, livestock farms and residential areas. The mainstream of the Anyang stream is classified into the 5th grade water as polysaprobic water area according to Saprobien system and the biotic index is over 2.5 in overall. Most of tributaries have 1~3 grade water limit with ${\alpha}$- and ${\beta}$-mesosaprobic except the upper and mid streams of Samsung tributary, in which pollution status is the lowest part. Though Sambong tributary is ${\alpha}$-mesosaproboic, biotic index is low because of the appearance of abundant benthos animals in farming and fishing villages.

The importance of urban and regional natural park increases because of the needs for preserving the natural resources and providing with natural recreation space in nature. This planning of natural park management should be established based on the research of the various natural resources in the park. But for the lack of effective data synthesizing methods and concepts, only some restricted factors for zoning plan are considered even though GIS computer system for large complex simulation is used. Therefore, in this study three ecological zoning models such as Basic Factor Model (BFM), Visual Landscape Model (VLM) and Comprehensive Ecological Model (CEM) are proposed and applied to Byounsan Peninsula Nature Park(BPNP) for comparison with the current natural park zoning. The BFM has three components -elevation, slope and vegetation. The VLM has applied with six components -elevation, slope, vegetation, road type, and the visual distance. Finally the CEM's modelling factors have included all of BFM, VLM components are added with the land use type, nature and historic resource factors. The zoning concept of BPNP was based on "Minimization" focused on the specific factors. But introduced modelling concept is "Optimization" based on the total ecological environment. So the result of the modelling has larger area for preservation and development zoning compared with the current zoning whose characteristics are ambiguous which allows the environmental destruction. The future study issues will be the determination of the weighting factor, component reconsideration based on the ground truth data and the agriculture residential area zoning.

This study is to evaluate the classification system of rural-villages remodeling components which is provided for improving the quality of life for rural community by improvement of settlement environment. To achieve this, rural-villages remodeling components are classified according to the spatial structure of rural area through analysis of literature, then we have examined the applicability through case studies after modification work which is based on experts's discussion and rearrangement by pilot investigation of researcher. In the classification system of rural-villages remodeling classified productivity area, residential area, community area in first group and this classification is divided into 6 space to production, 4 space to residence, 5 space to community in second group by literature search, pilot investigation of researcher and field survey. The subject elements surveyed a total of 123 through the literature search, additionally, 1 element at a space to production and space to community in field survey for types in zoning cases. As a result, categories and items are decided that it is included 125 target elements.

The study looked into the effect of housing poverty on the depression level for the elderly in depth. In this study, we defined housing poverty as sub-minimum standard housing conditions, excess housing expenditure and housing instability. In order to verify the correlation of two variables, a mediating model structured by social welfare service was used which gave out the 4th Korea welfare panel data. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The results revealed that housing poverty of the elderly directly affected their depression level. Also the satisfaction of social service showed a partial mediating effect between housing poverty and depression level. But the mediating effect of social service experience between housing poverty and depression level was not statistically significant. The outcome of this study indicated the practical and social intervention to promote a mental health of the elderly by improving residential environment.

This study empirically analyzes the effect of pedestrians' personal and household characteristics and accessibility to public facilities on a walking safety satisfaction (WSS) level. The aim is to find ways to improve vulnerable pedestrians' WSS level and contribute to the creation of an inclusive urban environment. As a result of the analysis, age and gender variables were important for elderly people, and education was an important factor for disabled people. The WSS level was impacted by the factors of single-person households, income, and residential areas. In the case of accessibility to public facilities, the greater the satisfaction with accessibility to public institutions, urban parks and green areas, and public transport, the greater the WSS for the elderly and the disabled. And, the greater the satisfaction with accessibility to commercial facilities, the greater the WSS was for the elderly's WSS. However, the satisfaction with access to medical facilities was the opposite in the case of the elderly.

Despite the recent economic contraction caused by the Corona 19 incident, interest in the residential environment is growing as more people live at home due to the increase in telecommuting, thereby increasing demand for remodeling. In addition, the government's real estate policy is also expected to have a visible impact on the sales of the interior and furniture industries as it shifts from regulatory policy to the expansion of housing supply. Accurate demand forecasting is a problem directly related to inventory management, and a good demand forecast can reduce logistics and inventory costs due to overproduction by eliminating the need to have unnecessary inventory. However, it is a difficult problem to predict accurate demand because external factors such as constantly changing economic trends, market trends, and social issues must be taken into account. In this study, LSTM model and 1D-CNN model were compared and analyzed by artificial intelligence-based time series analysis method to produce reliable results for manufacturers producing furniture components.

This study analyzed the bicycle traffic patterns and identified the influence factors for each traffic purpose using the household traffic conditions survey for Seoul. The results are summarized as follows. First, as a result of surveying the bicycle traffic ratios according to the administrative dongs, there was a difference of 14.2% by region. Second, various personal characteristic variables, such as age, gender, income, occupation, and housing type, affect the bicycle mode choice, and bicycle passage increases when using facilities in residential areas. Third, among the neighborhood environments, the bicycle traffic for commuting purposes appeared to increase more in the areas of higher land use mix and lower crime rates. In addition, the bicycle road density and the inclination of the area commonly affect bicycle travel for commuting, shopping, exercising, and leisure.

Previous studies on the factors affecting residents' migration have shown that residents who feel dissatisfied with their residential environment are more likely to move to another area than those who feel satisfied. The main purpose of this study is to investigate the subjective evaluation of the decline of the place and its impact on the intention to stay. This study used the data from Hankyoreh 21 survey of the residents who have been residing in the declining regions. The main finding of this study is that residents have a much higher propensity to stay as they become older. The fact that residents' staying intention tends to increase with age seems to be closely related to physical and economic constraints of older residents. Therefore, it can be inferred from the result that the elderly are more likely to be exposed to disadvantageous environments than the young residents in the declining regions.
