As a solution to environmental issues, such as climate change response, the carbon neutrality strategy, urban heat islands, fine dust, and biodiversity enhancement, the value of urban green spaces and trees are becoming important, and various studies dealing with the effects of trees for environmental improvement are being conducted. This study comprehensively considers the preceding studies on planting tree species, planting structure, planting density, and planting base to propose a direction for the planting renewal of green areas in urban parks and applies the findings to a renewal plan to improve the urban environment through landscaping trees. A field survey was conducted on the planting status of Seoul Children's Grand Park, a large-scale neighborhood park in Seoul, and based on the survey data, a planting function evaluation was conducted, and areas needing improvement in planting function were identified. The planting function evaluation was carried out considering the park function setting, planting concept according to spatial function, and planting status. As a result of the study, the direction of planting renewal according to functional change was derived for each stage of planting function evaluation. Increasing the green area ratio is a priority in setting up park functions, but user convenience should also be considered. As a concept of planting, visual landscape planting involves planting species with beautiful tree shapes, high carbon absorption, and fine dust reduction effects. Ecological landscape planting should create a multi-layered planting site on a slope. Buffer planting should be created as multi-layered forests to improve carbon absorption and fine dust reduction effects. Green planting should consist of broad-leaved trees and herbaceous layers and aim for the natural planting of herbaceous species. For plant species, species with high urban environment improvement effects, local native species, and wild bird preferred species should be selected. As for the planting structure, landscape planting sites and green planting sites should be composed of trees, shrubs, and trees and herbaceous layers that emphasize ecology or require multi-layered buffer functions. A higher standard is applied based on the planting interval for planting density. Installing a rainwater recycling facility and using soil loam for the planting base improves performance. The results of this study are meaningful in that they can be applied to derive areas needing functional improvement by performing planting function evaluation when planning planting renewal of aging urban parks and can suggest renewal directions that reflect the paradigm of functional change of created green areas.

To effectively lead "Innovative City Season 2", it is important to investigate whether the creation of an innovative city has a positive effect on the revitalization of the hinterland town economy. This study explores the effects (external effects) of increases in the number of workers at public institutions in the innovative city of Jeollabuk-do, located closest to the hinterland town (Jeonju-si). In the results, we show that increases in the number of workers positively affected the commercial real estate market, which is one of the barometers that show the revitalization level. On the other hand, the effect was found to be limited to the new downtown commercial real estate market with good accessibility and modernized facilities and services. This suggests that the innovative city adjacent to the hinterland town meets the purpose of the innovative city to some extent by generating a positive external effect, especially in accessible and modernized areas. To further expand the positive spillover effects of an innovative city on the hinterland town, it is necessary to expand public institutions for relocation, improve settlement conditions, and establish a practical cooperation system between specialized public institutions and hinterland-related industries.

In this study, an empirical analysis was performed with regards to traditional markets in Seoul, South Korea to find which physical maintenance elements, such as facility improvement for successful urban restoration, have greater effects on the expectation and activation awareness of successful urban restoration. This study targeted traditional markets located at the center of Seoul, which are visited by many domestic and international tourists as well as general consumers and are revitalizing the downtown area. A survey was conducted to collect a total of 515 completed questionnaires. Data analysis was performed using SPSS 23.0 and AMOS 22.0. The results of the analyses in this study indicate relevant urban invigoration factors (psychological, physical, diversity, functional, and stability factors), and it was observed that the expectation of urban regeneration was under the direct influence of the invigoration factors. Such a finding is meaningful in that it suggests a set of criteria to evaluate the concept of traditional markets in a comprehensive manner for successful urban regeneration while highlighting relevant invigoration factors for traditional marketplaces for the purpose of urban regeneration.

For buried gas pipelines, cathodic protection system shall be installed to protect against corrosion. The surveys of pipe-to-soil potentials for the gas pipelines should be carried out at the test box more than once a year. In urban, the test box is usually located on the driveway, therefore, it is difficult to measure the potentials. That is, traffic control is needed when carrying out the measurements of the potentials on daytime, or measurements of pipe-to-soil potentials at the test box located on the driveway have to be carried out in the late night when the traffic is light. We have developed remote potential monitoring system using the solid reference electrode and the wireless communication technology for the purpose of removing above problems. We have installed the developed solid reference electrodes at a site and monitored the potentials by wireless communication. Measured potential values were transferred to the server in office and analyzed. We have found the pipe-to-soil potentials transferred to the web server make no difference to the potentials measured directly on the site.

As GIS analysis method began to be introduced in late 1980's, studies of land development applying the GIS also started to be proceeded in various fields. Since 2003, Land Suitability Assesment has been adopted in order to prevent national land from development thoughtless for the environment and to plan appropriate national land management in terms of green development. Land Suitability Assessment System II based on diverse GIS analysis method such as Contour Analysis, Overlay Analysis, Network Analysis was particularly adopted to draft plans of specifying and altering of exclusionary zoning as well as installing and maintaining of urban planning facilities. But there has been a lot of problem, like an inaccurate basic data and assessment indicators, unmatched threshold, and contradicted evaluation result between each evaluating systems. Even though it is suited to an evaluation criteria, grade distribution is applied to start at 20, and development-centered evaluation result is offered. Now, we observed how suitability values and grading were changed, ordering to change grade distribution system from $20{\sim}100$ to $0{\sim}100$. In result, it showed changes of grades in some parcels. And in case of suitability values, 87% of parcels decreased to minimum 1 point, maximum 70 points. It means that changing grade distribution system of assessment system II doesn't have only influence on suitability values and grading but it is also an empirical analysis because of considering both development and maintenance.

Since the first 12 ones were designated in 1969, 228 places have been designated as tourism sites, and about 70 percent of them were designated before the 2000s. It shows that changes in most of tourism sites are needed in terms of physical, functional and environmental aspects. However, there are still not enough academic progress and policy consideration regarding the decline of tourism sites and the regeneration of them. This study aims to find the causes of decline and the factors to activate in tourism sites, to draw important conditions to recover the attractiveness of tourism sites in decline from the comprehensive analysis of causes and factors, and to apply the conditions to a real case in severely declining stage. According to the findings, the conditions for recovery could be restructured into four categories: 'The upgrade of hardware such as facilities in tourism site', 'the development of software such as contents and programs', 'the reinforcement of local capacity and institutional grounds' and 'the expansion of functions and the building of networks with various external stakeholders such as expert groups, related enterprises, talented individuals and so forth.

It constitutes a very important preliminary step to analyze how city image is assessed in order to determine the direction towards a desirable city image in planning on an urban landscape for future city image. This study aims to quantify the recognition and evaluation of a city image on the part of citizens, using multidimensional scaling and correspondence analysis. Furthermore, this study hopes to contribute to the quantified policy-making for improving city image by understanding how professionals and civil servants in the related field tend to recognize such image. The results from the study are as follow: 1. The image of Daejon City tends to be assessed strongly in the light of its history, dynamics, and size. While the City is recognized as new and changing in general, the civil servants consider the city as modest, and the professionals as mediocre. Therefore, the City should strive to conceive its own unique identity, which would lessen the current image of modest and mediocre. 2. Gap river, Dunsan New Town, and the Daeduk Reseach Complex turn out to be the symbolic representative venues of Daejon City, inspiring the city’s image. In contrast, Yoosung Springs, the original town, and the Expo Park do not fit the image of the City. The need to renovate these places presents itself. 3. As for the questions using “like” and “not-like”, citizens and professionals show the tendency of not liking the city’s image, whereas civil servants like it. It follows that the City needs to highlight its “modern and high-technological” image, illuminated by Dunsan New Town and Daeduk Reseach Complex. 4. An image positioning drawn from a correspondence analysis shows that the City of Daejeon can be classified as an administrative and horizontal city. As opposed to the prior simplistic analyses of city image, this study attempts to diagnose it accurately, so as to help with the gearing towards city images in the future.

Urban parks are important spaces of ecological and socio-cultural value to citizens who lead busy lives in increasingly complex and densely populated megalopolises. However, creating and maintaining city parks takes the will of the authorities to put it into practice and provide the attendant financial resources. That explains why we are focused on the budget aspects for the Seoul Metropolitan City in relation to creating park spaces. Our findings were as follows: 1) The overall city budget has steadily increased, but the budget allocated to Green Seoul Bureau and new park development has decreased since 2011. 2) As for elected officials, the budget grew during the time of the first, third, and fourth mayors as the creation of parks was considered to be a major priority, but after the sixth popularly elected mayor, the budget was sharply cut. 3) About 10% of the budget was allocated to the parks managed by the self-governing districts, compared to the ones under the direct management of the city. Furthermore, the analysis of the average annual budget for each park and how long (in terms of year) the budget for each park is invested showed that it was classified into three different types of category. Local governments adhere to the principle that their budget must be compiled and expended for a single year, which makes it hard to establish and push ahead with a long-term plan. However, as parks and green areas should not be approached from a short-term perspective for performance but from a long-term perspective, securing the consistent amount of budget is essential. This study has significance in that it attempted to analyze the budget issues related to parks, which has not been studied in depth so far, but the subject in this paper was limited to the budget for Green Seoul Bureau. Therefore, further research is needed because the parks managed by the self-governing districts were not considered.

The study shows solutions of long-term unexecuted urban park and activation plans to facilitate the business promotion of Private Park Developers. This study conducted a feasibility analysis to determine if the business of a special case is applicable. The result of this study is as follows about three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park. First, the three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park are the forest type Neighborhood Parks. Businesses of a special case's park developing cost(average 0.4%) have a relatively low percentage. It is most affected by Land Compensation(average 33.8%) and building construction expenses(average 59.1%). Second, long-term unexecuted urban parks' Land Compensation and building construction expenses seed capital are excessive. The Bongsan Park balance floor space index is 179 percent; a reasonable profit floor space index is 220 percent. The Mareuk Park balance floor space index is 351 percent; a reasonable profit floor space index is 420 percent. The Jungoe Park balance floor space index is 327 percent; a reasonable profit floor space index is 400 percent. Third, to facilitate the business of special cases in deliberating, Bongsan Park should change its second class general residential area. Jungoe Park must change the quasi-residential area and semi-residential area. Mareuk Park must change the general commercial area. In this way, the feasibility of promoting private park projects will be improved.

Forest healing is a natural method that utilizes various natural environmental factors of forests to enhance immunity and to heal mental and physical pathologies. The aim of this study is to suggest implications for the future development of forest healing by analyzing the characteristics of facilities and programs in 28 national and public healing forests in Korea. The concept of forest healing and programs is defined, and healing forests operating in Korea are classified by size. The facility operation and program characteristics of healing forests were analyzed according to size, and the results were used to suggest a future direction for the development of domestic forest healing. The research results are as follows. First, domestic healing forests have gradually been reduced in size since they were first opened in 2009, which is the cause of the competitive creation of local governments. Second, healing spaces, forest paths, and programs for the elderly, pregnant women and disabled should be expanded. Third, lodging programs need to be expanded, and subsidies for usage fees from local governments are required. Institutional supplementation should be provided to link program development and facilities and to clarify procedures and standards for forest healing facilities.
