This study is aimed at classifying different types of parks in Gwang-Ju city and providing efficient Planning and guidelines to satisfy the needs of park users. The first stage of this study was accomplished by site surveys of neighborhood parks in Gwang-Ju where park types, locations, neighboring conditions, park layout, and other physical environments were surveyed for the specific status of parks. With those basic data, urban neighborhood park types were classified into different categories: 1) urban neighborhood parks; 2) riverside neighborhood parks; and 3) natural(mountain side) neighborhood parks. For the second stage of this study, behavior patterns and satisfaction were investigated to provide empirical data on the relationship between the physical environment and human behavior. The main findings of this study can be summarized as follows: 1. The highest level of satisfaction for the users of urban neighborhood parks in Gwang-Ju city is the accessibility of the parks which are small but located in neighborhoods, The users tend to visit the nearby parks regardless of size. 2. The users have relatively high levels of satisfaction for urban neighborhood parks which have a lot of green zones or park facilities. Therefore, the park planner should consider the natural environment in the park area and should reconsider the type of park in the planning process. 3. The different types of urban neighborhood parks in Gwang-Ju city do not affect the level of satisfaction and the motivation of park visits. However, the accessibility of the parks is the most important factors of users' satisfaction regardless of the type of the park. 4. The level of user satisfaction for all of the urban neighborhood parks in Gwang-Ju city indicates that the users have a relatively low level of satisfaction. Especially, 26.2% of the users have a high level of dissatisfaction. The new parks, which have recently been developed, have a higher level of satisfaction than the old parks which have a lack of facilities, insufficient maintenance, and poor management planning in the park. 5. As a result of factor analysis, all city neighborhood parks showed a similar tendency with urban type parks, but showed a tendency that was different from the other park types.

This study is a contribution to the geographical understanding of Daejeon Area, playing the role of principal center of Choongchong Province. This area has been urbanized associated with Daejeon Basin, an important natural unit in the middle part of South Korea. In order to understand Daejeon Area in geographer's view, it is necessary to elucidate geomorphological environment of Daejeon Basin and urban expansion pattern associating with it. Our research is converged into dual objectives: one, description and interpretation of basin's landforms; other, urban expansion relating with geomorphological condition. Daejeon's urban expansion has progressed from the border zone of Daejeon Basin toward into the basin, and then vice versa. Relating to rivers valleys in the basin, the urbanization in the basin has been extended from the river valleys of lower order toward those of higher order. Understanding of the geomorphological mosaique of Daejeon basin is an important base for that of urban mosaique of Daejeon City.

This study is to find out the proper planting and utilization plans for climbing plants in urban community gardens. As a result, a majority of respondents claimed that it is acceptable to plant climbing plants in their plots of the community garden. In particular, those who have experiences with gardening activities responded that climbing plants could be allowed in the community gardens. There was a high tendency to use climbing plants in community gardens for aesthetic or ornamental use and for creating fences. Many respondents also claimed that the climbing plants should be planted outside or on the edge of the garden and that the plants should not cross over to other plots. Those who responded that the climbing plants should be planted outside or on the edge of the community garden wanted to use the plants for aesthetic or ornamental use. Those who wanted to use the plants for creating shades responded that the plants should be planted outside or on the edge of the garden. For proper planting of climbing plants in the community garden, it is necessary to consider the height of the vertical plant support depending to the gap between the plots in the community gardens, the shape and color of flowers, leaves, and stems for aesthetic use, and mixing of plants for the duration of the shade period. Accordingly, introduction of climbing plants can be considered to increase the diversity of plants in urban community gardens.

This study puts its purpose on presenting an integral system of representative urban landscapes, public design and colors, in practicing urban design in the context of local identity. An integral design of public design that successfully plans and executes local identity, and changes recognition of integral management of urban design, is suggested as followings. Firstly, when the catchment area is divided in metropolitan area, it should be reset according to the natural environment condition regardless of administrative area system like city and county. It is the method to classify the metropolitan area by researching and analyzing geographical condition, weather condition, soil and vegetation in detail and subclassify it by the visual commonness of natural environment. Secondly, it is necessary to access the urban landscape, public design and urban color from the overall aspect emphasizing the plan for each field and local identity. They should be practiced by the role and category of each field on the basis of consistent design strategy and instruction but the cooperation system is required as a process to reinforce and specify the mutual limit. Thirdly, the artificial structure is constructed through artificial adjustment depending on the urban formation process and the development time point. Therefore, it is necessary to pay attention to the rapid urban development, the change speed and the landscape formation of each age. It is necessary to classify the type of artificial landscape by age and form similarity and separate the area that should be generalized and controlled by entire metropolitan area form the area that should be specialized by basic local government.

Both domestic and overseas urban drainage systems have been actively researched to solve the problems of urban flash floods and the flood damage that is caused by local downpours. Recent urban planning has been designed to better manage the floods of decentralized rainfall-management systems, and the installation of green infrastructure and low-impact development (LID) facilities at national ministries has been recommended. In this study, we use the EPA SWMM model to construct a decentralized rainfall-management network for each small watershed, and we analyze the effect of the drainage-capacity improvement from the installation of the LID technologies in vulnerable areas that replaces the network-expansion process. In the design of the existing urban piping systems, it is common to increase the pipe size due to the increment of the impervious area, the steep terrain, and the sensitive entrance-ramp junction; however, the installation of green infrastructure and LID facilities will be sufficient for the construction of a safe urban drainage system. The applications of LID facilities and green infrastructure in urban areas can positively affect the recovery of the corresponding water cycles to a healthy standard, and it is expected that further research will occur in the future.

This study conducted observations at 72 traffic lights and road signs in Sejong-si, Korea from March to June 2019 in order to analyze nest-site, nest-site characteristics and feeding behavior in Tree sparrow (Passeer montanus) in urban. Feeding behavior during breeding season in 2019 was investigated at 10 Town representing traffic facilities installed on the road located in the center of the city and 10 Riverside Geumgang river's riverside road. We fitted both general linear model and regression model to our field data and estimated the spatial variation of initial date of the first feeding (i.e., being date of breeding) and the total number of caterpillar fed by parents per hour. Our results showed that the frequency of nest building on artificial structures, such as traffic lights, was about 26% higher and about 8 days earlier in the riverside. In particular, the first feeding was significantly faster when the nearest distance between nest to green field as foraging site was shorter whereas there was no significant effect of the number of nest within 50 meters on the first feeding. Number of caterpillars fed by parents was higher in the Riverside than in the Urban, and especially the number in the second brood was sharply decreased in the Urban. As we estimated average amount of caterpillars per hour to 446 traffic safety facilities in Sejong-si, it was estimated that Tree sparrows fed 18,742.8 caterpillars per hour during the breeding season. In this study, we showed that characteristics of nests built in artificial structures and feeding behavior in order to analyze effects of environmental condition in urban on life-history traits during the breeding season. Finally, we discussed the conservation of birds in urban and pest control effects.

An important factor in assessing the beneficial qualities of a city's intersection spaces can be measured by examining a pedestrian's approach to the space and calculating the openness observed in the overall design of adjacent buildings. These spaces are influential, since they offer opportunities for pedestrians to spend time and take in views of the surrounding environment. The intersection of horizontal components in cities such as Bundang-si and Suwon-si can provide a sense of openness or greenness. We believe that there is a need for careful analysis and study of such components, as defined by designations in Bucheon-si research, and that this study can give important insights for future urban planning and design. When assessing the openness of an intersection, a key variable is the reported rate of perforation, which factors into the greenness of a space. Because of the large and varied scope of this research, this rate is highly variable, as there were many differences between each site. In descending order of average ratios: Seongnam-si, 41.79% > Bucheon-si, 35.40% > Suwon-si, 30.42%. The data compared for each city was divided into study sites selected at downtown locations as well as in urban outskirts. Openness and greenness were analyzed at each downtown and outskirt site. A summary of the results shows a decreased openness average of -2.63% in downtown locations versus outskirt. The greenness ratios in urban outskirt areas were 4.86% greater than downtown locations on average. As it relates to the results of this analysis of openness, the comprehensive property zoning for each city was determined as a ratio of residential to commercial designations. This study analyzes view points within urban cross intersections in the downtown landscape. It presents basic data and research directions to promote a better environment with regard to openness, and consists of an analysis of the relationship between a variety of physical components.

This study is based on the premise that a garden space is a place that not only requires physical labor but also encourages conversation in the gardening group. We suggest the use of urban gardens as a place to revitalize local communities by promoting people to participate in various event programs. Through the theoretical study, we set the requirements that can be applied to "urban garden events". We developed measurement items and scales to be used as variables of each construction concept. Our survey was conducted on adults aged 19 and above who visited the 8th Korean Urban Agriculture Expo. Out of total 310 copies of the distributed questionnaire, only 298 effective samples were used in the empirical analysis. We can assume that people want to revitalize local communities based on the fact that 71 (23.8%) participants said they thought the purpose of the event is to achieve unity among residents. Throughout analysis, 15 of the necessary items were confirmed and classified into two factors: image of event (Factor 1) and evaluation item (Factor 2). As a result of verifying the relationship between educational level for Factor 1, age was significant in five items and education level was significant in six items. For Factor 2, four items were effective in relation to education level, while significant results were not found in relation to age. These results are expected to be significant if the intellectual curiosity of the residents is satisfied and the demand base of the urban garden events according to the characteristics of city people is expanded. Based on this study, it is necessary to conduct research on the use of urban gardens as an event with social functions as well as various programs that can be carried out in gardens to build and revitalize the community.

It is well known that urban relative humidity has continuous decreasing trend owing to the influence of urbanization. The change of relative humidity is directly influenced by two factors, namely, temperature effect and water vapor effect in various urban effects. In this study, the temperature and the water vapor effects on the relative humidity change were analyzed by using monthly mean relative humidities for a long period(1961~2013) in Busan and Daegu. The major results obtained in this study can be summarized as follows. Firstly, the urban dryness was caused mainly by water vapor effect in summer. But, for the other seasons, the urban dryness is mainly due to the temperature effect. Secondly, the relative humidity in Busan is on the decrease until now. This phenomenon is similar to another Korean huge cities such as Seoul, Daejeon and Incheon.
