The overall purpose of this study was to investigate pedestrians and commercial business men and employers' recognition on management of street trees and green spaces along street sides. The followings were main results of this study. Both pedestrians and commercial business men and employers mostly perceived positive influence of street trees on urban environment and their business. In addition, pedestrians gave higher scores of positive influence of trees function than those of commercial business men and employers. Pedestrians showed strong intention to participate management activities of street trees or green spaces. This study indicated that negative perception on street trees came from improper management rather than existence of street trees. Therefore, more intensive management actions are needed.

In order to address housing issues, alleviate the concentration of urban populations, and resolve other issues regarding residential spaces, large residential complexes have been developed in Korea since the 1970s. The changes to the residential culture due to such development projects propagated rapidly, making the apartment complexes the most representative form of housing in Korea. In developing such large-scale complexes, plans for public open spaces, which play an important role in formulating the quality of residential environment, have been mostly the same, only utilizing the spaces remaining after planning other types of spaces. The current study looks at the case of Tama New Town development project, a Japanese new town development project that has a similar public open space system in large scale residential complex development projects in Korea. In doing so, the current study aims to identify the features of public open space plans. In the conclusion, the study first finds that various public open spaces must be reviewed and introduced in term of predicting social demands. Second, the study suggests the policy-makers should actively introduce pedestrian paths as a public open space. Third, the study deduces the planning implications of applying the principle of original landscape preservation.

The objective of this study is to develop the design criteria of traffic island considering pedestrian level of service (LOS). In pursuing the above, this study gives particular emphasis to suggesting the minimum design space of traffic island in order to maintain pedestrian LOS C and D, and the critical pedestrian traffic volume that reflects the intersection geometry (2 lanes per direction) through the simulation analysis. The main results are as follows. First, the spaces of 160 traffic islands, which meet the pedestrian LOS C and D and reflects the pedestrian traffic volume by signal cycle, are drawn by using a commercial simulator VISSIM. The relevant spaces of traffic island in terms of both the pedestrian LOS and the pedestrian traffic volume are evaluated to range from $3.0m^2$ to $41m^2$. Second, the critical pedestrian traffic volume for the operation of traffic island is evaluated to be 1,000-1,300 person/hour at LOS C and 1,600-1,800 person/hour at LOS D, respectively, when a cycle of 120-150 seconds were applied to a intersection with two lanes per direction.

This study investigated how external environmentally-friendly factors adopted to improve the quality of outdoor spaces have been designed and used in the construction of apartment complexes. The goal of this study is to determine what areas should be improved through environmentally-friendly ways to create natural outdoor spaces in apartment complexes and enhance their availability and usefulness. For this study, 21 environmentally-friendly factors were chosen and a checklist by specific item was prepared. This study examine how these items were applied to basic planning, detail design, and construction in 4 target areas. As a result, it was found that the development of environmentally-friendly residential areas was an ultimate goal of the project during basic planning and design. All target areas focused on developing an inner greens network, eco-pond, brook, and pedestrian track as well as the growth of a variety of plants. Some differences have been observed, however, in terms of method. Furthermore, due to economic and technological problems and poor construction site conditions, green walls/green roofs/pedestrian tracks/use of rainwater have not been properly promoted. These kinds of problems must be improved through the development of environmentally-friendly construction methods and materials, the expansion of natural grounds areas, economic support, a satisfactory repair and maintenance system.

This study describes an improved model for estimating pedestrian LOS (Level of Service) by utilizing the space occupied by pedestrians. The method introduced the concept of conflict along the bi-directional pedestrian flow which enables calculating conflict area and average travel time in walking. Especially, the method incorporates the idea of generalized density concept which can consider effective walking area and pedestrian flow rates that might vary during the analysis period. After establishing methodology, adjustments of pedestrian LOS criteria in term of walking space occupied by pedestrians were performed. As a result, walking-occupied space at capacity level is 0.68 and corresponding pedestrian flow rate was calculated as 80 persons/min/m, while different pedestrian-occupied spaces were ordered to classify LOS at the points where the gradient changes. Furthermore, the statistical verification of service levels has shown that there is significant difference among all LOS categories at 5% significance level.

The purpose of this study is to investigate the causes of conflict that arise from public pedestrian passages installed in apartment complexes through a survey of residents' perceptions and to investigate the effects on the satisfaction with and necessity of the public pedestrian passage. This has significance as a preliminary research into determining solutions to conflict related to public pedestrian passages that are open spaces, accessible 24 hours a day to pedestrians including people who live outside of the apartment complex. The result of the residents' perception survey showed that there is conflict due to the public pedestrian passage. The main problem was the noise-related variables. While management and safety variables were also perceived as problems, privacy and ownership infringement variables were not. These problems were reduced to four factors through a factor analysis: unfavorable incidents, environment management, ownership infringement, and safety crimes. Analyzing the effects of the above factors on the satisfaction with the apartment complex, satisfaction with the public pedestrian passage and the necessity of the public pedestrian passage, demonstrated that the unfavorable incidents factor influenced all the variables. The safety crimes factor, which is an extended concept of the unfavorable incidents, affected both the satisfaction and necessity of the public pedestrian passage. The ownership infringement factor was found to affect the satisfaction of the public pedestrian passage only, and the environment management factor did not affect all the variables. In planning and managing public pedestrian passages, avoiding incidents and crimes should be considered as a priority to increase the satisfaction of residents and solve conflicts.

I investigated the relationship between social support, environmental factors, and color design within the public spaces of healthcare facilities. Through a comprehensive literature review and case studies from major hospitals in the United States, the United Kingdom, and Scotland, I explored how these elements contribute to public spaces' overall concept and function. The study emphasizes the need to establish a clear relationship between the social functions of these spaces and their physical and environmental characteristics. By examining theoretical frameworks and observed examples, I analyzed the impact of color design and the integration of internal and external spaces. The findings highlight that well-designed spaces, especially those utilizing effective color schemes and connecting indoor and outdoor areas, enhance user satisfaction and support healing processes. The results underscore the importance of communal spaces in healthcare facilities for psychological and social healing. I conclude that these spaces should be intentionally designed to foster social interactions among patients and visitors by improving pedestrian accessibility and incorporating social support structures.

One of the key problems in the design of high-rise commercial complex is how to guide reasonable pedestrian distribution in commercial space. In this study, pedestrian distribution in three high-rise commercial complexes in Shanghai and Hong Kong was studied using spatial configuration analysis software Space Syntax and quantification of physical elements in commercial spaces, such as functional attractiveness, entrances, escalators, level variations and passage width. Additionally, in an attempt to integrate functions with spatial integration and spatial depth, two combination variables, the spatial coefficient of function (IF) and spatial depth coefficient of function (F/D), were proposed. The results of the correlation analysis and multiple regression analyses reflected the following: (1) Regarding the influence on pedestrian distribution, there was a synergistic and complementary relationship between function and space; (2) The comprehensive flow distribution analytic model could successfully interpret flow distribution in high-rise commercial complexes and its R Square ranged up to about 70% in the three cases; (3) The spatial coefficient of function (IF) and spatial depth coefficient (F/D) could effectively integrate functions and spatial configuration, which could help close the gap between over-emphasis on function in commercial research and the lack of consideration of function in space-syntax analysis.

This study aims at presenting a plan to build an open space network system in the city of Daejeon, assuming that parks and the green space system as a broad concept are to make a network by connecting open spaces such as parks, green spaces, squares, pedestrian roads, historical spots, etc. In the case of old downtown in Daejeon, this study examined the possibility of applying an open space network in the city of Daejeon and categorize them according to the findings from examining the case area, which enables to make a plan for building an open space network system in Daejeon. As a result, public offices and business buildings as an active open space have public open spaces in front of buildings and these front public open spaces are connected to pedestrian roads(gray open space). Since these pedestrian roads are consequently connected to large parks and rivers(green or blue open space), this overall spatial sequence can form an open space system. In addition, parks and green spaces, which have been fundamental elements so far, exist in relatively small and scattered areas at the center of the city. Hence, more parks and green space are needed to improve a park and green space system. However, it is very difficult to create new parks and green spaces in downtown, especially in old downtown areas. Therefore making an open space network system which spreads out over the whole city will form a healthy open space network in the downtown area.

Residential site should have pedestrian road passing through the center of the site just for convenience and safety. However, apartment complexes developed in the past, the sites are just stuck by walls and pedestrian roads are not placed, inhabitans have difficulties for facility use and safety. Therefore, residents solve the problems as follows: they utilize the spaces, between apartment building and the wall, as walking route, and demolish the parts of the wall for connecting sites. In this study, it was thought that pedestrian road could be emplaced at the wall space between sites. For this, a low-rise apartment complex in Gwangju was selected developed in 1990s, and whether the space for pedestrian road was examined. The width from 2.4m to 8.0m could be secured, and there could be placed the pedestrian road at the wall space. However, this study is limited for the possibility of securing space, for the opinion of residents that might be damaged from the pedestrian road did not reviewed.
