The purpose of this study is to derive and adapt the Valuation Factor of urban regeneration scientifically and synthetically, which is the basis of developing a rational plan for urban revitalization. For this, we have selected 37 factors relating to urban regeneration as outlined in preceding studies and inquiry about importance of factors. we analysed he Valuation factors influencing he importance of urban revitalization through a questionnaire which was completed by inhabitants and expert groups in Gwangju Metropolitan City. From he results of he Factor analysis using SPSSWIN(VER.14.0), it was found that the factors which influence the importance of urban regeneration are Environment, Function, Resources and Policy Factors. Environment Factor comprises amenity, culture, beauty and convenience, The while the Function Factor comprises interchange, information, complexity and security. This classification has credibility because of the high factor loading through the Varimax Factor Analysis and is due to a high Cronbach's coefficient. There is a strong correlation between the classified factors through correlation analysis. Finally, through AMOS (Analysis of Moment Structure) 16.0 it was found that the upper classification is credible because main suitability index confirms recommending an admission standard.

Recently, the construction and plan of super-tall building is attention link of new town development or urban core regeneration. Super-tall Buildings have many advantages and a lot of affects in urban contexts. Also, construction of super-tall building is will be able to social problem like urban core's decline, loss of openspace, incompatible urban scape, traffic congestion of urban core. But, compares to super-tall buildings affects in urban contexts, there was not extra ordinary study about super-tall building by the urban scale approaches. Therefore, need about study materplan planning of the site which is made to meet super-tall building and urban contexts. There are two main processes in this study. First, to analyze the factors affect to masterplan planning of the super-tall building's site. Through the analyzed factors, classify type of super-tall buildings and identify the type's state. Second, to classify and set the elements of masterplan planning factor in the site. Identify the masterplan planning factor's state by deployment materplan planning factor set the current applied to the constructed super-tall buildings. Through this process, identified the recent trend and providied the basic elements of materplan planning of super-tall building's site.

The purpose of this study was to investigate factors and variables which have significant effects on visual preference of urban stream in Taejon city and to suggest design & management information for urban stream. These works consist of two phases. First, we tested the Hyechon college students' visual preference for 36 spots of urban stream slide and then selected 10 spots slide by the Sturges' formula. Second, we analyzed factors and variables of visual preference of urban stream using the semantic differential scale method and then processed using descriptive analysis, factor analysis and multiple linear regression analysis. The major findings of this study can be summarized as follows. 1. The difference of landscape adjectives between the highest score of visual preference slide (No.10) and the lowest score of visual preference slide (No.2) was cleanness. 2. Three factors, the nature, the cleanness and the movement, were derived from the factor analysis. 3. Factors covering the visual preference of urban stream have been found to be the landscape of urban stream, the nature, the cleanness, and the movement. The visual preference factors of urban stream need to be considered in creating or restoring the ecological urban stream landscape.

Background and objective: This study was conducted to obtain empirical data for deriving necessary items for the creation and management of gardens in urban agricultural parks while maintaining the publicness of the place by examining the difference in perception among park visitors about the gardens in the public parks. Methods: A survey was conducted on users of urban agricultural parks in 6 locations and 113 copies of the questionnaire were collected. After understanding the demographic characteristics and the current use of the garden, we identified the importance of the necessary items for the public gardens. Results: 108 subjects(95.6%) responded that gardens are needed in urban parks, for psychological and emotional health (26.2%) and for interaction and friendship with family and neighbors(23.2%). For use of garden crops, most were private sales(96 subjects, 64.4%), and both sales preferred to partially donate their crops. Most used communal gardens operated by public institutions(30.1%). It was found that 96.4% of the respondents were satisfied with gardening activities, and 107(94.7%) of them showed their intention to participate in the gardening in the future. The Kaiser Meyer Olkin value was .848 and the significance level was .001, proving the validity of factor analysis. The factors were named composition elements(Factor 1), management items(Factor 2), convenience elements(Factor 3), and operational facilities(Factor 4). In the survey on the creation and management of gardens in urban agricultural parks, there were no statistically significant differences, but all items had correlations. Conclusion: The results have reflected the needs of actual users in establishing the plans to operate urban gardens, thereby having great utility value as the basic data for continuous garden management. Further research can be conducted to derive detailed elements that can guarantee sustainability of urban gardens and suggest high-quality data for management of gardens in urban agricultural parks.

In order to effectively evaluate the urban water security, the study investigates a novel system to assess factors that impact urban water security and builds an urban water poverty evaluation index system. Based on the contribution rates of Resource, Access, Capacity, Use, and Environment, the study adopts the Water Poverty Index (WPI) model to evaluate the water poverty levels of 14 cities in Gansu during 2011-2018 and uses the least variance method to evaluate water poverty space drive types. The case study results show that the water poverty space drive types of 14 cites fall into four categories. The first category is the dual factor dominant type driven by environment and resources, which includes Lanzhou, Qingyang, Jiuquan, and Jiayuguan. The second category is the three-factor dominant type driven by Access, Use, and Capability, which includes Longnan, Linxia, and Gannan. The third category is the four-factor dominant type driven by Resource, Access, Capability, and Environment, which includes Jinchang, Pingliang, Wuwei, Baiyin, and Zhangye. The fourth category is the five-factor dominant type, which includes Tianshui and Dingxi. The driven types impacting the urban water security factors reflected by the WPI and its model are clear and accurate. The divisions of the urban water security level supply a reliable theoretical and numerical basis for an urban water security early warning mechanism.

This study is to predict the spatial expansion of urban areas by applying CA(Cellular Automata)-Markov technique considering MCE(multi-criteria evaluation) and MOLA(multi-objective land allocation) of factor analysis. For the 10 administration districts$(3677.3km^2)$ including the whole Anseong-cheon watershed, the past six temporal land use data(1973, 1981, 1985, 1990, 1994, 2000) from Landsat satellite images were prepared. During this period, the urban area increased $233.71km^2$. Using the 36 indices composed of topological characteristics, population and land use change, the final factor map of MOLA was produced through 5 maps of MCE. Using 1990 and 1994 land use data, the 2000 predicted urban area of CA-Markov with factor map showed 0.06% improvement of absolute error comparing with that of CA-Markov without factor map. By the CA-Markov technique considering factor map, the 2030 and 2060 urban area increased $58.94km^2(0.78%)\;and\;60.14km^2(0.81%)$ respectively comparing with 2000 urban area$(313.19km^2)$. The 2030 and 2060 paddy area decreased $93.28km^2(2.54%)\;and\;93.65km^2(2.55%)$ respectively comparing with 2000 paddy area$(1383.23km^2)$.

In recent years, the natural damage associated with flood disaster has been dramatically increased. However, there is no rational method which reflects urban characteristics to estimate the regional safety assessment for flood disaster. The purpose of this study is to develop the regional safety assesment model for urban flood. Flood risk and reduction assesment were estimated by using the linear sum of the Z score of the assessment factors and the weight value of each factor from the expert survey data. And then the regional safety assessment was estimated by subtracting reduction factor value from risk factor value. GIS tool was used to estimate the factor assesment and integrated regional safety. This study can be used to determine the priority of flood protection project, execute the flood insurance and establish the urban plans and the flood mitigate plan.

Urban regeneration is a worldwide challenging project, showing a great interest in the sector. In order for Korea's urban regeneration to be settled successfully in the early stage, it is necessary to analyze and review the opinions and business performance of the urban regeneration areas. The purpose of this study is to evaluate the urban regeneration planning factors affecting urban regeneration on the satisfaction of citizens, public administration and region. This study surveyed the residents and experts of the Yeongju city, Gyeongsangbuk-do, where urban regeneration is actively doing with active participation of residents and local government. Based on the data of the survey, this paper performed frequency analysis, correlation analysis and multiple regression analysis as a analytic methods. The results revealed that 'community factor' was the most important factor to the satisfaction of residents in the urban regeneration project in progress. In the final stage(at present), both 'community factor' (0.387) and 'physical factor'(0.454) were found to have a significant effect on satisfaction. While the satisfaction from 'the economic factor'(0.111) has slowed but it has increased with 'the physical factors' in the process of regeneration project, 'the social factors'(-0.007) shows a downward trend. If the role of social factors and community factors are supported at the beginning step of the urban regeneration project, the physical factors and economic factors are continued to lead a sustainable urban regeneration in the long term.

This study was conducted (i) to recommend the high-scored education method as a adaptable method, and (ii) to find the most influential factor among the three acceptability components (feasibility factor, stimulation factor and reliability factor) to urban or rural residents. The accept-ability score of each health education method currently existing in urban and rural area was estimated. A total of 257 households in Guro 6-dong, Seoul, and 233 households in Jeomdong-myeon, Yeoju-gun, were sampled by interview survey using questionnaire. The four types of health education methods used in this study are; printed matter method, mailing service method. personal contact method, and group contact method. The major findings obtained from this research are as follows; 1) In urban area, the highest-scored in terms of acceptability is the personal contact method, followed by the mailing service, the printed matter, and the group contact. The mailing service method is found to be effective especially for the intelligent group people. 2) In rural area, the highest-scored in terms of acceptability is also the personal contact method, followed by the group contact, and printed matter method. In general, the group contact method is effective toward both urban-poor and rural housewives (especially in stimulation factor). To improve the health consciousness of the residents, there arises the need for the existing education program into better organized and diversified one and for educating health-educators by providing in-depth health knowledge.

The aim of this paper is to examine the determinants of residential satisfaction and attachment according to the urban multi-family dwelling types. On the basis of the surveys, the factor analysis and regression are employed as the empirical analysis on residential satisfaction and attachment in Daegu metropolitan city. The major findings are as follows; First, as for post-occupancy evaluation of residential environment of building and outside, the residents of complex type of multi-family housing satisfied with most of items more than studio type except the location, amenity facilities around building and utilities fee. Second, about the Residential Satisfaction and Attachment by types, the residents of complex type of multi-family housing satisfied with most of items more than studio type too. Third, the determinants in residential Satisfaction of complex types are 'welfare and amenity facilities factor', 'maintenance factor' and 'location factor'. On the other hand, the determinants in residents of studio type are 'inexpensive rent fee factor', 'welfare and amenity facilities factor' and 'maintenance factor'. Going forward, this research will help us better understand residential satisfaction from the point of residents and find new ways to improve resident satisfaction and attachment.
