The urban regeneration project is an activity that promotes the economy in underdeveloped commercial or residential areas and maintains urban communities through improvement of living in residential areas. Through this study, various successful cases of urban regeneration at home and abroad and surveys related to urban regeneration in Bongsan Village, Yeongdo, Busan were collected and analyzed. Key keywords for each case were derived, grouped, and top keywords were created. The 13 top keywords were evaluated using Likert's 5-point scale, and AHP was conducted for the 10 keywords that were finally selected. As a result of AHP analysis, the preference for "spatial and physical properties" was derived in the order of "publicity", "sustainability", and "identity". The preference of "content and system properties" was derived in the order of "resident participation", "convenience", "locality", and "local government participation". It is necessary to present a role as a design guideline for establishing urban regeneration designs in relation to various urban regeneration projects that will become more active in the future through the analysis of preferences of urban regeneration keywords derived through this study.

The construction of smart communities is a new method and important measure to ensure the security of residential areas. In order to solve the problem of low accuracy in face recognition caused by distorting facial features due to monitoring camera angles and other external factors, this paper proposes the following optimization strategies in designing a face recognition network: firstly, a global graph convolution module is designed to encode facial features as graph nodes, and a multi-scale feature enhancement residual module is designed to extract facial keypoint features in conjunction with the global graph convolution module. Secondly, after obtaining facial keypoints, they are constructed as a directed graph structure, and graph attention mechanisms are used to enhance the representation power of graph features. Finally, tensor computations are performed on the graph features of two faces, and the aggregated features are extracted and discriminated by a fully connected layer to determine whether the individuals' identities are the same. Through various experimental tests, the network designed in this paper achieves an AUC index of 85.65% for facial keypoint localization on the 300W public dataset and 88.92% on a self-built dataset. In terms of face recognition accuracy, the proposed network achieves an accuracy of 83.41% on the IBUG public dataset and 96.74% on a self-built dataset. Experimental results demonstrate that the network designed in this paper exhibits high detection and recognition accuracy for faces in surveillance videos.

This study explores consumers' intention and attitude to a small scale cohousing for the aged, which provide local communities with the small residential spaces where seniors can feel at home. Questionnaire method is performed, and 193 data were gathered in Jeonju city. The results are as follows. When respondents have a professional job, a owned house size($66-99m^2$, $132m^2$ or more), and disease or dementia, their intentions to move into a community friendly co-housing for the aged is high. The shortcomings of this housing are perceived low by college or graduate school graduates, but middle or high school graduates do not perceive low them. The respondents with the annuity of less than 4,000,000(KRW)/month perceive them in normal or higher, while those with the annuity of 4,000,000(KRW)/month or more perceive them in low. This annuity will be as a cost criterion to accept to move in this housing.

This study explores consumers' intention and attitude to a group home for the middle class elderly, which provide local communities with the small residential spaces where seniors can feel at home. Questionnaire method was performed, and 193 data were gathered in Jeonju city. The results are as follows. When respondents have a size of house (66.2-99.1 $m^2$), elderly disease or dementia, and their annuity or their spouse annuity, and when they are much old, their intentions to move into a community friendly group home for the aged is detected. The respondents and their spouse with the pension of more than 2,000,000 (KRW)/month have an intention to move to this group home. Also, they and their spouse with annuity have positive attitude to it, and these goups with the pension of more than 2,000,000 (KRW)/month have low negative attitude to it. So, house size, health condition, and annuity are variables to determine to move into it.

Recently, due to the growing concern of the public in rural amenities and hobby farming works, much more urbanites, especially near-retirees, have been interested in rural life style than before. However, in spite of popular preference to ruralities, little has been known about their demand on retired rural life. Therefore, this study examined urbanites' attitude to preparatory works for out-migration, preferred residential site conditions and life style in the countryside. For this purpose, data were collected from a survey with the sample of 386 urban residents aged 40 to 65 rho hoped moving into the countryside after retirement, through structured questionnaires. Descriptive statistical works were performed using SPSS/PC windows program. The major findings of this study were as follows; (1) Host of urbanites, who answered in this study, planned to prepare ex-urban movement in their fifties and to put into practice in their sixties. (2) Key factors of location decision on movement were proximity/accessibility to centre city, medical service level, and distance to their family or friends. And about a half of respondents wanted second home in the countryside. (3) Most favoured rural life styles were nature-friendly well-being and hobby/healthy firming. Generally, the respondents of this survey had the positive attitude to do works in their later life, especially preferred to farming and volunteering in their communities.

Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.

This study empirically investigates the degree of physical exclusiveness of multi-family housing estates and its socioeconomic effects. By combining various physical elements devised to blockade and control the entrance to the estate as well as housing units, it constructs the index to quantify the degree of physical exclusiveness for the multi-family housing estates of more than 300 households in Seoul. The statistics reveal that the degree of physical exclusiveness has increased over time and therefore, as a representative example, two-thirds of the estates are now equipped with barricade at the entrance, which often symbolizes 'gated community'. The estimation result of hedonic price model show that physical exclusiveness has a significant positive effect on housing price. The household survey data for the case study estates also demonstrate that the residents in the estate of higher degree of physical exclusiveness put a higher housing value on socioeconomic 'prestige' as well as 'community', beyond physical 'security', and have closer neighborhood relationship with the residents inside the estate. However, there is no significant difference in neighborhood relationship with the outside residents depending upon the degree of physical exclusiveness.

Urban park facilities and services offer a number of opportunities to fulfill individual, social, economic, and environmental benefits. Urban parks, provided through political measures as public goods, require balanced distribution in order to ensure social equity. The primary objectives of this study are to analyze the accessibility of urban parks and to examine whether urban parks are distributed equitably. GIS and statistical methods were used to investigate correlations between accessibility to neighborhood parks and socioeconomic status. As results, percentage of low-income population within the city was negatively related to park accessibility. Low-income dominated residential area, such as Sujeong-gu and Jungwon-gu have large low-income communities and less park accessibility compared with Bundang-gu, which are dominated by high-income residents. So, results from this study indicate that urban parks are not distributed equitably within Seongnam city. Therefore, creative strategies to provide urban parks for areas in need through the utilization of vacant lots, abandoned sites, and schools sites are necessary. Furthermore, budgetary priorities should be set to create new parks and revitalizing parks within the city's older neighborhoods are also needed.

In this study there was the analysis of government incentives and resident support of public crematoriums, typically identified in Korea as a locally unwanted land use (LULUs), in the metropolitan area. The study looked at what government programs would be potential incentives for allowing the crematoriums to exist in metropolitan communities. Such programs were diverse, with projects focused on: enhancing resident welfare, increasing resident income, funeral facilities and management consignment, community oriented programs, education, funding, and others. Among them, it was found that residents were most in support of programs for enhancing resident welfare and increasing income among residents. In order to resolve the complexities of community support for LULUs and government incentives to shift public perception of cremation, three main policies are proposed. First, it would be necessary to compliment additional project support policies which provide medical services, resident prefered projects, and improvement of substandard housing. Second, it would be important to establish ordinances concretely identifying residential support projects based on community needs assessment. Lastly, it would be of the government's best interest to build policies for resident supported projects that reflect local conditions and the residents' demands for allowing non-preferred facilities to be built, and then to analyze the economic feasibility of these demands.

In coastal residential communities, especially along the coastline, flooding is a frequent natural hazard that impacts the area. To reduce the adverse effects of flooding, it is recommended to elevate coastal buildings to a certain safe level. However, post storm damage assessment has revealed severe damages sustained by elevated buildings' components such as roofs, walls, and floors. By elevating a structure and creating air gap underneath the floor, the wind velocity increases and the aerodynamics change. This results in varying wind loading and pressure distribution that are different from their slab on grade counterparts. To fill the current knowledge gap, a large-scale aerodynamic wind testing was conducted at the Wall of Wind experimental facility to evaluate the wind pressure distribution over the surfaces of a low-rise gable roof single-story elevated house. The study considered three different stilt heights. This paper presents the observed changes in local and area averaged peak pressure coefficients for the building surfaces of the studied cases. The aerodynamics of the elevated structures are explained. Comparisons are done with ASCE 7-16 and AS/NZS 1170.2 wind loading standards. For the floor surface, the study suggests a wind pressure zoning and pressure coefficients for each stilt height.
