One of the major factors which increase urban temperature is roads. This paper is aimed to investigate the effect of urban roadside vegetation on the road surface temperature. For this, surface temperature was measured at 18 spots using the thermal imaging camera in terms of road components including use of roadside land use, roadway, sidewalk, roadside vegetation and vegetation median barrier. The size of the roadside vegetation and related urban road characteristics were also measured. In terms of the effect of roadside vegetation on a decrease in road surface temperature, the roadside land use as a green area or open space was the highest, followed by the size of vegetation median barrier and the size of roadside vegetation. Besides road surroundings, an increase in the green zone such as roadside vegetation and median strip vegetation has a significant impact on lowering road surface temperature. Therefore, a good solution for reducing urban heat island effects would be to increase the area of roadside vegetation and green areas along roads.

The research described in this report was conducted to find out how elements of the natural environment contributed to the formation of Chang'an, how its water system reinforced its status as the capital city, and what role it took for its urban function based on studies of the canal constructions. During the period of Sui and Tang, Chang'an built a sophisticated water system using Qu(渠), the irrigation facilities. In the water system, hills are called Yuan(原), and rivers with the proper environment to be developed plan into urban infrastructure facilities for irrigation water, urban living water, the composition of garden-based facility, reservoirs, and others. They improve agricultural productivity and, consequently, increase the city's competitiveness as well as contributing to the urban infrastructure, serving as a convenient source and ensuring the quality of life was abundant. So, the urban effects of the water system have raised the capital's status. With the contribution of its pragmatic water system, Chang'an not only performed its urban function brilliantly, but also established itself more firmly as a capital city.

This study intends to analyze the relationships between images of arboreta or botanical gardens and the policy supports related to carrying capacity. For this purpose, a questionnaire survey was distributed to 723 public sites nationwide. The results consisting of an exploratory factor analysis, a confirmatory factor analysis, a correlation analysis, and a structural equation method showed that the images of the arboretum or botanical gardens contained 3 factors: cognitive, affective and shape factors. The cognitive factors greatly affected the policy support related to carrying capacity. The policymakers of the arboretum or botanical gardens can consider cognitive elements of images as important aspects in the planning and management factors to improve the support of visitors related to the policies of carrying capacity for sustainable use.

Personal distance is one of the basic and important concepts in the field of Environmental Psychology in influencing personal space, visible or invisible territoriality and psychological carrying capacity of contemporary urban dwellers. This study aims to analyze the bench users' behaviour and personal distances in urban parks for the first time in Korea, one of the representative landscape spaces in urban areas. For these purposes, this study has adopted a blind observation and pictorial analysis for bench users in Yeouido Park in Seoul. The main results of this study show that the average interpersonal distance between female and male(intimate relationship) is 47.5cm, the distance between female and female is 53.2cm, and the distance between male and male is 70.3cm. These results mostly support the previous western study results, but the interpersonal space and territoriality of Koreans in urban parks may be smaller than that for western societies.

This study investigated the effects of urban farm program on the participants' sense of community. Three public urban farms in Seoul were selected and surveyed. The results were as follows: First, the effects of the urban farm program on the sense of community were verified by a multifaceted analysis. There were significant differences in the interaction and sense of community between urban farms with and without regular programs. Program participants showed higher level of activity, interaction and sense of community compared to non-participants. Program participation was the most important factor in the path analysis. Second, the number of participating group, residential ownership and duration were important factors in the sense of community. This implies that urban farm programs should target house owners with long duration, in particular socially disadvantaged classes such as single-family and elderly household. Third, diverse cultural programs related to the regional society gained higher satisfaction than the simple agricultural educational programs.

This study was carried out to suggest an experimental base in selecting the cold tolerance of plants. The cold tolerance of the plants were subject to laboratory low temperature treatments and cold processing time were evaluated using both electrolyte leakage and regrowth test. The Logistic model of nonlinear regression analysis was used to evaluate the lethal temperatures that were predicted with the range of $-16.1{\sim}-24.4^{\circ}C$. The order of low-temperature resistance was Sedum reflexum > S. spurium > Ophiopogon japonicus > S. album > S. takevimense > Dianthus chinensis. At the lowest temperature of $13.4^{\circ}C$ the electrolyte leakage value of the plants were lower than 50% demonstrating that they could be applied stably to the roof installed in Korea during the winter with the lowest temperature of $-13.5^{\circ}C$.

This study intends to analyze the structural relationships among the servicescape of theme park, the affective image and the place dependence of visitors, one of the most important factors of place attachment. For this purpose, this study selects Lotte World in Seoul as a study site and conducts a questionnaire survey focused on visitors who visited the site previously. The results of an exploratory factor analysis, confirmatory factor analysis and structural equation method show that esthetics and amenity factors among servicescape of theme park affect the attractiveness and comfortableness of the affective image of visitors positively, and two factors of visitors' affective image also affect the their place dependence positively. Tourism planners or landscape designers can consider these useful servicescape elements of theme park as important planning and managing factors in order to improve the images of theme parks and the level of place attachment.

Following the September $12^{th}$, 2016 earthquake in Gyeongju-city, the observation can be made that South Korea is not a non-earthquake country. Because of its particular characteristics, urban green spaces are good sites for protection during an earthquake but studies regarding the suitability of park green spaces as a form of earthquake shelter are few, making it difficult to highlight the function of park green spaces as emergency shelters. The purpose of this study is to identify indicators for suitability impact factors of comprehensive parks as emergency earthquake shelter zones. Using the Delphi method, three rounds of survey were implemented. According to the analysis results of Average value, CVR, Consultation and Convergence, ten candidate indicators were removed in the candidate group. Twenty-seven suitability impact factors of comprehensive parks were retained, including 8 indicators in the field of safety, 6 indicators in the field of accessibility, and 13 indicators in the field of service effectiveness.

Strengthening the protection and management of very old trees is an important aspect of urban site preservation, urban design and construction. Rating various danger factors to evaluate the degree of danger posed can help to create the correct protective countermeasures. In order to develop the danger evaluation index, this study performed four round surveys by using the Delphi method and collected opinions from experts in related fields. Necessary indexes were fully added in the first and second round while the indexes falling beyond the guidelines were deleted. From the final analysis results, five areas derived a total of forty-one indicators to create a degree of danger index from vigour status, growth and development status, diseases and insect pests, soil status, and management status. The degree of danger evaluation index can provide basic data for the protection of very old trees.

This study found the possibility of using cemeteries within the locality as field trip destination. A comparison between Korea and the United States of America's active progress has derived the difference and the implications. Therefore, this article found that the cemetery has sufficient resources based on experience-learning place within the community. Therefore, when the active educational program was developed; it gained more abundant resources for education, as well as provided more different educational opportunities for the students than now. As the result of comparison, the reason why the educational program is actively progressing in the American cemeteries is that a beautiful and fresh environment has been built up such as a park or garden in a cemetery and has been preserved as a healthy forest ecosystem. Furthermore, it is because they actively used the cemetery within a community as the subject. If our cemetery can be renovated and the funeral culture can be changed to break down the image of an avoidable unpleasant facility, it would play a role as a field for learning experience.
