The purpose of this study is to segment and examine urban farmers behavior by applying a two-step cluster analysis and multi-nominal logit model. The data were collected by a telephone survey with two-staged stratified random sampling in the cities around the country for the purpose of acquiring representative data. Respondents were asked to describe their awareness of urban agriculture, their agricultural activity, and sociodemographic characteristics. Among 2,000 cases, 381 cases(19.1%) which were of participants in urban agriculture were analysed in SPSS. From the findings, 27.3% of respondents had heard the word 'urban agriculture', and 25.5% of them regarded themselves as urban farmers. Four different clusters were derived from two-step clusters based on motive, place, companion, area and hours. They were 'Large scale hobby farming(cluster 1)', ‘Weekend farm/ hobby farming(cluster 2)', 'Land/ Self-supporting farming(cluster 3)', and 'Small scale hobby farming(cluster 4)'. The result of multinomial logistic regression showed that there were significant differences among these four segmented groups in terms of age, city size and housing type. In other words, there is quite a possibility that urbanites select different urban farming types according to their socio-demographic profiles. Therefore, the urbanite profiles can be used as the basis for promoting policy of several urban agriculture types. According to the result, policy directions for facilitating urban agriculture were presented.

The purpose of this research is to suggest directions for urban planning and policies for the creation of a happy urban environment. To achieve this objective, this study extracted the urban environment characteristic elements that were expected to affect the levels of individual happiness and empirically analyzed the factors that affect the happiness levels of people. To determine the elements of the urban environment, this research analyzed the variables, urban environment characteristics, such as physical environment, natural environment, social environment, and individual characteristics. Regarding the physical environment of the city, a lower population density and a higher level of walking environment satisfaction showed a high level of individual happiness. In terms of the natural environment of the city, more spacious park areas and higher green area satisfaction showed a high level of individual happiness. Finally, regarding the social environment of the city, social trust was found to affect the happiness levels.

Flooding in urban areas is caused by heavy rains for a short period of time and drains within 1 to 2 hours. It is also characterized by a small flooding area. In addition, flooding is often caused by various and complex causes such as land use, basin slope, pipe, street inlet, drainage pumping station, making it difficult to predict flooding. Therefore, this study analyzes the effect of each basin characteristic on the occurrence of flooding in urban areas by correlating various basin characteristics, whether or not flooding occurred, and rainfall(Limit Rainfall), and intends to use the data for urban flood prediction. As a result of analyzing the relationship between the imperviousness and the urban slope, pipe, threshold rainfall and limit rainfall, the pipe showed a correlation coefficient of 0.32, and the remaining factors showed low correlation. However, the multiple correlation analysis showed the correlation coefficient about 0.81 - 0.96 depending on the combination, indicating that the correlation was relatively high. In the future, I will further analyze various urban characteristics data, such as area by land use, average watershed elevation, river and coastal proximity, and further analyze the relationship between flooding occurrence and urban characteristics. The relationship between the urban characteristics, the occurrence of flooding and the limiting rainfall amount suggested in this study is expected to be used as basic data for the study to predict urban flooding in the future.

Urban space is a place that shows the behavior, experience and lifestyle of residents. Also by the combination of local attributes and assets, creating a space that reflects the unique image of the city. For the development of the city, it is important to actively reflect the identity of the space created by the difference of each space. In this study, we focused on the disparate of space and found the characteristics of urban space. And psychological factors on disparate images of the spatial analysis. As a result, 14 spatial image characteristics of Busan showed difference. In terms of dimensions, it could be classified as an natural, artificial, dynamic, static images. Also, the preference cluster of individuals showed a positive response in naturalness, openness, gentle slope and static space.

Since the 21st century, major cities in Vietnam faced housing shortage and there was a lack in office spaces. As a result, construction companies from over seas provided mixed-use apartment as a new type of urban housing. A large number of mixed-use apartments are built in big cities such as Hanoi and Ho-chi-minh City. However, research on mixed-use housing in Vietnam is insufficient. Therefore, the main purpose of this study is to understand the characteristics of mixed-use apartments and have an effect on the development of urban housing in Vietnam. This study focuses on examining the planning characteristics of mixed-use apartments in Hanoi. The research will be based on 10 mixed-use apartments that are already built or expected to be built in a few years. Therefore, this study starts by looking into the history of the Vietnamese urban housing. The study focuses on the transformation of urban housing since 2000. Then, the study will mainly focus on examining the mixed-use apartments in different aspects, in order to analyze the planning characteristics.

The purpose of this study is to clarify the characteristic of urban heat island intensity in urban area formed at a basin. Thermal environments for basin-type cities are influenced by significant topographic relief winds. In this study, we analyzed the diurnal variations of the heat island intensity according to meteorological condition and season using AWS(Automatic Weather observation System) data in Daegu Metropolitan area for 1 year(3/April, 2003 $\sim$ 2/April, 2004). In this study, we defined the urban heat island intensity as the air temperature difference between two points, the downtown and the suburban area. The suburban area is located at valley mouth around the western tip of Daegu. The results are summarized as follows; 1. The maximum heat island intensity was recorded at early morning under the meteorological conditions, calm and clear 2. The heat island intensity was strong in the order of winter, fall, spring and summer. 3. The heat island intensity came out minus values in the afternoon. This phenomenon is known as a com mon for basin-type cities. 4. The heat island intensity was twice or more in clear and calm than not so.

The agricultural population, the farming, the agriculture of our country has been decreased more rapidly than those of other countries. Also, the changing speed of the rural village in Korea has shown a similar trend. By considering the urbanization process and migration state caused by the economic growth and the increasing level of relative poverty in comparison with the urban area, it has been necessary to go through the impoverishment and slum-orientation of the rural area. In our country, the rural village became old age. So, the collapse is predicted to a population shortage if such trend is continued in the village society. according to investigate, Many urban peoples have opinion that migrates to a farm village. but those not migrate to rural community. The mainly reason is low life environment. therefore it is need the plan that the urban people migrates to a rural village, and must have the plan to be engaged in the agriculture. lt was the rural-fishing New Town development project that started in 2009 for 30~40 years's urban people. This study is about characteristic and improvement of Rural-Fishing New Town development project.

Urban-Hanok emerged as a result of urbanization of Hanok in the modern period. In particular, Urban-Hanok has been mass-produced from the early 1920s, when the population is concentrated in cities, until the middle. Large-scale development by the professional developer has been developed in large-scale land rather than individual client because housing shortage was serious problem. 11 Gahoe-dong was made in 1935-36 is representative Urban-hanok area of Bukchon. It was formed through division of large-scale Land in 1930's. In the 1930's, the large-scale development projects of Urban-Hanok was triggered by the two events. One is Land Investigation Project performed by the Japanese government to capitalization of property, another is the pro-japanese bought the large scale-land in Gahoe-dong at bargain price from The Japanese government. Each lot has still a topographical characteristics such as land-dividing quality, the way of development, characteristic quality of urban-tissue. 11 Gahoe-dong, Urban-hanok area was developed two ways. First, development have been adapted to the topography. The lots have reflected topographical conditions such as land cutting area, a retaining wall, land-diving was maintaining the original topography almost. Second, it was street oriented development. The lots have developed sequentially along the street. So, the lots's shape and size is different each. For this reason, this area distribute various type of Hanok.

The aim of this study was to suggest characteristics and strategies of urban development focused on Transit Oriented Development (TOD). For this study, the relevant concepts of TOD were reviewed, and the types of urban development based on TOD was surveyed. As a case study, 7 TOD projects implemented in advanced countries were analyzed in the terms to change in urban spatial structure, urban balance development and connection of public transportation. The conclusions are as follows. First, the regal system and the support mechanism for success of the public-private partnership are essential for TOD. Second, the role of public sector leads planning, implementation and management should be emphasized in the development process, and mitigation of the development density and revision of a municipal ordinance for promoting TOD are necessary. Third, a public transportation plan and land-use plan in the downtown areas should be integrated, and the enlargement of the urban infrastructure through public assets by the local authority is essential.
