As the Private-initiated Park Development Project (PPDP) is being actively implemented, there are concerns about the deterioration of ecosystem services due to the development of long-term unexecuted urban parks. This study aims to analyze the impact of the PPDP on the ecosystem services of urban parks by examining Central Park, which is PPDP No. 1 in Gwangju, Gyeonggi-do. A study was conducted using system thinking to comprehensively understand the changes in the ecosystem services due to the PPDP. As a result of the study, the first reason for implementing the PPDP was the local government's lack of financing. Second, it was found that the creation of urban parks through the PPDP initially deteriorated cultural services yet improved them over time, while the regulating and supporting services continued to decline. Third, trade-offs appeared between urban parks' ecosystem services (i.e.., cultural services, regulating services, and supporting services). Through this, it was confirmed that it is necessary to prepare measures for planning and managing urban parks that can reduce the trade-off between the ecosystem services of urban parks. The results of this study suggest that it is necessary to understand the relationship between environmental changes and ecosystem services over time when establishing urban park creation plans and management.

This study is to analyze the base of selection and feature of description on Korea-related content in Japanese curriculum(geography and history) and high-school geography textbooks. Japanese curriculum requires that there are two or three neighbor countries to be selected and their contents consist of life and culture and have to compare with those of japan in view of understanding and respect on similarity and difference. The content of physical environment is only dealt as factors influencing on life and culture because regional teaming of neighbor countries focus on it. Dok-do is described with conflict region in most of textbooks. But some textbooks describe Dok-do with territory of Shimane-Hyun in Japan or devide like japanese territory on the map. There are described han-gul(Korean language), confucianism, buddhism and christianity, han-bok(Korean clothes), rice and soup, bulgogi(Korean meat dishes) and scissors, spoon and chopsticks, ondol(Korean floor heater), etc. with the cases of specific Korean life and culture. And, exchange between Korea and Japan focuses on more cultural view increasing recently than political and economical view. Then Japanese high-school geography textbooks humanize geography because of they focus on life and culture and promote not only knowledge and understanding but also altruism and empathy because they focus on similarity and difference through comparison between neighbor country and Japan. This shows how to able to practice regional teaming in globalization and multicultural society.

The user behaviors in the parks around the commercial area may have different characteristics in comparison with the behaviors in typical neighborhood parks because they may be affected by nearby commercial facilities. The purpose of this study is to explore the characteristics of park users'behavior considering adjacent environments in the neighborhood parks located in central business district of Daegu and to suggest improvements and complements for the construction of new parks and remodeling current parks. According to the results, the land values were high and the percentage of deteriorated buildings was low around Gukchae Reward Movement Memorial Park and 2.28 Central Memorial Park. However, the commercial facilities were entirely declined along with a drop in land values around Gyeongsang-gamyeong Park and old people used this park more than young people. In terms of the purpose of park use, users of three parks had indirect behavior patterns related near commercial facilities rather than using directly park facilities and the age groups of park users were similar to the user groups of nearby commercial facilities. Also, the determinant factors of satisfaction with park use were varied depending on the difference of age groups of park users and park characteristics. Therefore, it is necessary to consider the effects of user age groups according to the changes of environment around parks for the construction and organization of parks.

The purpose of this study was to explore the influence of the topography and the neighborhood facility on the aged people's social network formation. The paper samples the aged people living in Changchun city located in a flat ground and Tonghua city located in a mountain region. Four selections of dwelling districts from the two cities are based on amount of the facilities maintaining the wealth and living area same to do the questionnaires. One hundred aged people are selected in the each dwelling district to fill out the questionnaires, and 386 valid questionnaires are finally obtained. The data obtained from the questionnaires are used to do some statistic analysis by using SPSS24.0 program. The results are shown as following: In the case of same amount of neighborhood facility for dwelling district, the aged people living in a flat ground use the facility more frequently and communicate more often with their friends and neighbors than the aged people living in a mountain region do, the social network forms more easily as well. In the other case of same topography dwelling districts, the aged people living in an abundant facility dwelling district use the facility more frequently and communicate more with their neighbors and friends than the aged people living in a mountain region do, so the social network forms more easily as well. Thus it can be seen that topography and amount of facility are significant influence factors of the aged social network formation.

Recently, due to the child-friendly city project being conducted by UNICEF, the movement to create a child-friendly cities has been actively promoted by the South Korean government. However, due to the lack of specific physical plans to improve the basic rights of children in the city, the project has been mainly implemented for educational and institutional projects. In this study, we investigated the activities of children and parents living in elementary school neighborhoods. Based on our investigation, we attempted to generate the desired results that can be referred to by physical planners looking to make changes to school neighborhoods by comparing and analyzing children and parents' activity range and life patterns in the neighborhood. The GPS and traffic log surveys were conducted as the primary research methods. The results of this study are as follows: First, both children and parents are most likely to walk in their neighborhoods. In addition, the use of private cars and school vehicles was high, but the use of public transportation was low. Second, the longer parents and children stayed together, the wider the range of their activities. Third, children who spent a lot of time with parents were more likely to have diverse life patterns than children who did not spend a lot of time with parents. Fourth, parents who live in elementary school neighborhoods frequently used commercial facilities and cultural centers around the school. Therefore, it is important to construct facilities around the school for parent-use.

We recorded the movement of wildbirds nine times at Hoam 1st Tunnel, Kkachisan Park, Deungneung pass to compare the movement between eco-corridor and neighboring crossing road from June to September, 2006. Among three areas, birds did not prefer the eco-corridor at pass type such as Kkachisan Park and Deungneung pass, however number of species and individuals were high at the eco-corridor at Hoam 1st Tunnel. Over 90m width and the slope location of eco-corridors can be beneficial for wild birds to enhance the movement along eco-corridors between isolated two patches. Average foliage volume under two meters showed the relation with bush nesters, and that from 7 to 8m had the highest relationship with canopy nesters. In Seoul city, target species should be considered at the construction of eco-corridors according to site characteristics, but Paradoxornis webbianus could be suggested as a main target species at eco-corridors. To enhance the movement of diverse wildbirds, we would implement that eco-corridors could be located at the slope area with the size of 1ha (over 90m width), eco-corridors could be planted and managed with the high foliage volume of shrub layer under twometers and canopy layer over 8 meters.

This study researched those universities for which fence opening and greening projects are being conducted by Seoul city. The forms of opened fences at 24 universities which have accomplished this project were classified into several types for each type of university, representative cases with many diverse facilities and active users were selected and investigated. The study was carried out using methods of field observations, literature review, and surveys. To maintain the confidentiality of the collected questionnaire analysis, the analysis of each type's usage frequency, overall satisfaction and a regression analysis with space environment and facilities, a one-way ANOVA for was used to validate the difference between types regarding satisfaction with the project. The results of usage type analysis were found to agree with the 3 analysis criteria-- installation location, user characteristics, and usage purpose--which were the legislative concepts. In overall satisfaction with facilities, it appeared that except for Seoul Women's College of Nursing with its rural district neighborhood type park, users were satisfied: with the small urban neighborhood park of Methodist Theological College, Konkuk University's small urban square park, and Sejong University's green space small city park. In general, users appeared to not have satisfaction with such features as fountains / hydroponic facilities, fitness facilities, and square facilities, which should be taken into consideration when pursuing further opening and greening projects. Regarding full satisfaction with the space environment, it was found that users were not satisfied with Seoul Women's College of Nursing's rural district neighborhood-style park, whereas they were satisfied with Methodist Theological College's small urban neighborhood park, Konkuk University's small urban square-style park, and Sejong University's green space small city park. In addition, it was shown that facilities use, convenience and privacy of the four parks were largely unsatisfactory for users, and that the small city parks located at roadsides were unsatisfactory regarding noise level, both of which should be most highly considered when conducting similar projects in the future.

Urban Green space takes charge of the important role for the physical activity and promotion of health to the residents. Therefore, this study is trying to examine the relationship between the various characteristics of green space and green space usage for physical activity and health promotion. A questionnaire survey was conducted to obtain the information about patterns of green space usage and perceived neighborhood environments for the residents living in Changwon-si, Gyeongsangnam-do(n=541). Geographic Information System(GIS) was used to construct spatial data about green space accessibility and physical neighborhood environments. A Multiple Linear Regression model was used to examine the association between the characteristics of green space and physical activity, perceived health status and BMI(Body Mass Index). The study results revealed that the residents' physical activities are positively and directly influenced by the number of available public parks and green spaces in the vicinity(${\leq}200m$). The frequency at which residents witness others exercising nearby or the perceived abundance of low-cost gym facilities also factor as positive influences. The closer to the park, the higher the number of parks and area of green spaces, the more comfortable the walk thereto and the denser the neighboring residential area distribution, the perceived health level was found to be the more positively influenced. Further, it was verified that BMI is correlated with the number of public parks and green spaces within 400 m of the resident's home as well as the safety of walkways, the density of neighboring residential areas, the ratio of road, and the density of crosswalk. The significant multiple regression models between the characteristics of green spaces and physical activities and perceived health level were extracted within the significance level of 10%. This study will contribute to provide better understanding the ways in which green space and neighborhood characteristics are associated with physical activity and health. The result of this research will be available in the landscape architecture plan aimed at improving the use of green space for physical activity and reducing obesity.

School facilities are important facilities in neighboring residential areas and occupy important physical and social positions. Not using school facility occur to an obstacle to the environment of the local residents and cause a great waste of local land resources, due to its size and location. Therefore, it is necessary to establish a system to identify the cause of the unsold school facility site and to prevent it. On the other hand, it is necessary to make quick use of the unemployed school facility site through conversion of usage.
