This paper aims to identify planting design for the renewal of Okgu Park, located in Siheung, Gyeonggi-do. I designate planting concept fit spatial functions and also suggest planting designs that are proper for a growth environment. The spatial functions of the research site are divided on the basis of the park facilities, its surroundings, and usage. To understand the planting concept, this paper looks into the distribution of plant species and the precise planting structure. To understand the planting concept and the current usage of shade space in the park, I examine the distribution of plant species and the precise planting structure. There are 48 kinds of plants, with Zoysia japonica area (28.84%), Prunus yedoensis (8.0%), Pinus thunbergii (6.73%) and Zelkova serrata (6.38%) taking up the majority. 27 places were chosen for researching the precise planting structure. The research shows that the average green coverage ratio is 38.14% and the average green capacity coefficient is $0.72m^3/m^2$. The growth defective rate of trees in the shade areas is estimated by averaging the classified growth conditions of individual trees per block of shade areas. Areas with an inferior environment for growth and low spatial usage in Okgu Park are selected as subjects for planting design. After comparing the spatial functions with planting concepts and analyzing the growth of plants, I identify $36,236m^2$ areas with inferior growth condition. I also examine structures and the surrounding areas to find areas that require urgent planting improvement, specifically identifying landscape space and shade space around the fountain and the buffer space nearby the North gate. I rearrange spatial functions in the selected areas to devise a planting design considering the existing vegetation, layer structure, and its usage. I set the planting concept and direction to improve the landscape of the selected areas through implementing a planting design so the park users can be satisfied with each space.

Nowadays, according to the interests in the environmental infinity for the housing complex, there are various studies going on for setting general ideas and plans of them. And in some of the leading places are applied by the infinity of the natural environment. So, by this study, I analyzed the classification and the system of the infiltrated facilities for the rainwater and then suggested the problems about these and the studies for the generalization of the infiltrated facilities for the rainwater based on my real investigation of the center of infiltrated facilities for the rainwater in the Kiheung, Sangal Kum Hwa Village designed and builded by the Korea Housing Corporation for building housing complex with the infinity of the natural environment. I grasped the realities based on subject investigations and designs and found out the infiltrated facilities for the rainwater in the subject. Those are the porous concretes, pebbles and cobbles. The problems in the subject are supervision of these places and a shoddy and fault constructions by the ignorance and lack of recognition for the construction. These will be solved by reconsidering of the infiltrated facilities for the rainwater. The system of the infiltration is that the rainwater of the top of the building flows into the brook in the subject through the field of the subject. There must be going to be leading studies on the effect of these facilities and influence on the environment for the generalization of the infiltrated facilities for the rainwater of natural environment.

This report designs a landscape plan of six reservoirs in Sihung city which has possibilities both in development and in destruction. The report suggests how to create a leisure space in harmony with the surroundings in Sihung city. Building a leisure town will create the local residents' demand in recreational activities and improve the amenities. Therefore this study analyzes eco-friendliness of the land, conditions of fauna and flora, the quality of water and the usage figures of the six reservoirs so as to develop those six reservoirs more eco-friendly. Based on environmentalism, the leisure spot development plan attribute the ultimate importance to local residents' pleasant leisure time and recreations. With this master plan, the report suggests expanding the city's green space, since the city has under 50% out of the optimal percentage of green space per person. In addition, the report intends to plan each six reservoirs developed separately but organically connected at the same time that those six can put together and become a Sihung Green Way which makes the city's leisure space a belt. Apportioning the six reservoirs development levels in order to balance the development, accumulating and arranging buildings and facilities in available spaces according to the governing law, and creating resting area, promenade and parking lot to make an eco-city. Also the report suggests conserving environment and regulating contamination such as ban on fishing to move forward sustainable development. Since the adventives predominate the site, introducing indigenous plants should be necessary soon.

In this study, the preferences with regard to floral design in a public space and the correlation between such preferences and the image features of the floral design types were identified. Based on the review of the related literature, the floral designs placed in a public space were classified into three types(the flower bed, container, and three-dimensional sculpture types) according to physical factors, and were classified into two types(the indoor and outdoor types) according to environmental factors. In the floral-design type classified by physical and environmental factors, the flower bed and outdoor types, respectively, were highly preferred. The factor that was found to have the greatest influence on the preference for the flower bed type was 'well-orderedness', which included the adjective categories 'harmonious', 'clean', and 'simple'; that which was found to have the greatest influence on the preference for the outdoor-type floral design was 'identity', which included the adjective categories 'symbolic', 'distinctive', 'harmonious', 'impressive', and 'clean'. It can thus be concluded that the plants that are effectively displayed in a public space can express the nature and identity of the city itself, can be a yardstick for giving value to the city and for evaluating it, and can be important components of the urban landscape. A design that is suitable for the purpose of each public space and that reflects the factors that exert an influence on the users' floral-design type preference should thus be developed.

There are still a number of "olles" existing with traditional alley characteristics in the inner city of Jeju. As a matter of fact, the renovation of old buildings and the protection of alley space are facing a dilemma due to the existence of less than 4m-width-roads in the area of "Mu-geun-sung". This study examines the current status of alley space in "Mu-geun-sung" area; and puts forward to the potential possibility and limitation of alley space regeneration via exploring the applicable scheme of building agreement. In the field survey, a number of regions in inner city of Jeju witnesses the existing majority of invaluable, conventional olles. So as to grasp the feasibility in "Mu-geun-sung" area, we designs a simulating experiment to carry out the Building Agreement; and compares with the current development model in this area. Building Agreement implies to establish gradually a separation of land ownership under the existing unified development of landowners and users, thus to explore a variety of land exploitation systems by separating land ownership and right to use land. As a result, the deterioration of the street landscape results from the increase of building storey numbers. The damages to the surrounding environment brought by the newly built buildings will be minimized as well as keeping the maximum building volume rate. Obviously, these measures will alleviate infringement to the traditional residential sunlight and privacy space effectively, and reduce the pressure from high-rise buildings to the alley space, so that the landscape of the alley will enhance to form a more comfortable alley environment.

Rooftop greenery has been used as a way to solve urban environmental problems by creating green space in densely populated cities. This study was carried out to suggest more effective designs for roof-garden at hospitals through a post-occupancy evaluation. The roofgarden of Asan Medical Center was evaluated with regards to setting, proximate environmental context, users, and design activity by a multi-method including plan investigations, observations, in-depth interviews and questionnaires. The results are summarized as follows; the users' main activities included resting, walking, and talking. A number of users were observed at shaded spaces sitting on such things as benches, pergolas, and shelters. The satisfaction of the users showed high satisfaction level except in the amount of shade, facilities, and shelter. The variables affecting a overall satisfaction were ‘accessibility’, ‘safety’, ‘quality of surroundings’, and ‘suitability for speculation’. By comparing the design concept with using pattern, designer's intention was not reflected sufficiently in several aspects such as ‘event deck for therapy programs’, ‘grove and path’, and ‘low planters’. This study suggests some design implications; it is necessary to furnish shaded sitting places for passive behaviors and pathways for walking or a light exercise. A wind-break wall with glass windows could widen the users' views in a limited space. Natural shade like tree shade or pergola are more desirable than artificial shades. As for the vertical location of the roofgarden, the middle floor could be better than top area for accessibility. Characteristics of building and users should be considered in detail to provide distinct spaces. Proper technical standards for the greening of artificial ground should be established.

This study proposes a method of developing authoring tool that can easily and intuitively generate diverse digital leaves that compose virtual landscape. The main system of the proposed authoring tool consists of deformation method for the contour of leaf blade based on image warping, procedural modeling of leaf vein and visualization method based on mathematical model that expresses the color and brightness of leaves. First, the proposed authoring tool receives leaf input image and searches for contour information on the leaf blades. It then designs leaf blade deformation method that can generate diverse shapes of leaf blades in an intuitive structure using feature-based image warping. Based on the computed leaf blade contour, the system implements the generalized procedural modeling method suitable for the authoring tool that generates natural vein patterns appropriate for the leaf blade shape. Finally, the system applies visualization function that can express color and brightness of leaves and their changes over time using a mathematical model based on convolution sums of divisor functions. This paper provides texture support function so that the digital leaves that were generated using the proposed authoring tool can be used in a variety of three-dimensional digital contents field.

The ultimate goal of this research is to establish the movement rights of people with physical disabilities. To achieve this goal, the authors have investigated the regulation and restrictions of physical facilities to guarantee the movement rights and investigated how well these facilities were constructed. The authors then have analyzed and compared the results. The purposes of this research are as follows. First, the authors investigated and analyzed the present conditions of selected public facilities to propose improvement measures for the disabled, pregnant and seniors so that they could actively participate in cultural activities as normal people do. Second, the designs resulting from this research are provided so as to be helpful to disabled people in everyday life, which is different from previously conducted research. Third, the authors have selected facilities with outdoor areas to differentiate the results from those reported recently through research conducted on indoor buildings. The final step of this research is to provide basic design data on outdoor areas to establish true movement rights for the disabled. According to these research findings, the shortest moving distance cannot be guaranteed only by establishing facilities that follow the Article 3 law about guarantee of convenience improvement for the disabled. If the movement path is not regulated, the facility standards may not exist in one part and the part itself may become obscured and the distance could become longer than necessary. Accordingly, for real movement rights the movement path should be guaranteed not to be violated by other obstacles. The results of this study offer convenience when moving within the outdoor space of cultural facilities by providing direct information for the disabled. The value of this study is that it is the first study on movement rights and movement paths for people with physical disabilities.

Importance of color in floral design has been emphasized for long time, but it is difficult to find out standardization of color for floral design and for educational system. Wedding bouquet is major and important part of floral design and it shows same problem. The research is concentrated on color image analysis of wedding bouquet designs which have been submitted for 'Interflora World Cup Competition' with the intention to utilize the study result as the basic information of floral design. Colors of wedding bouquets from 20 different countries were analyzed. All of designers chose high brightness and saturation more for designing the bouquets. Warm colors and cold colors have been taken in similar portion. Blue color has been rarely used and it is probably because of the rarity of blue flowers. This study shows each continent has different color preference. European designers used wide variety of colors while Asian designers preferred red color. From this study, we found that color image scales of wedding bouquets represent 8 images out of 12 representative images. Four exceptions are 'clean', 'elegant', 'gentle' and 'modern' images.

The purpose of this study is to establish how community garden spaces should be used to restore communities engaged in village-rehabilitation projects. To achieve this purpose, we have analyzed the perceptions of local residents conducting a town-development project. The community reviewed the benefits of having a garden to improve the residents' quality of life and comfort. Given the role of gardens in revitalizing communities, it is necessary to build spaces where residents can relax and enjoy community life. Those who participated in this study hoped that their community garden would provide shade and relaxation, a children's play area, green spaces, and places for conversation. The space and facilities provided by community gardens vary, in accordance with the expectations and needs of each community. It is therefore inappropriate to apply uniform garden designs to all community gardens. Between 20% and 25% of a community garden should be allocated to each of the following: community space, ornamental space, and space for relaxation. As plants that provide shade and help to maintain the ecosystem are strongly preferred in community gardens, all plants should be chosen for their environmental benefits and functionality, rather than aesthetics. Residents may be willing to participate in a range of activities, including community events, the cultivation of plants, and garden management. Towns must therefore set up programs to support these activities. It is essential to continue studying and investigating the formation of community spaces and facilities, reflecting the characteristics of each community.
