The purpose of this study is to classify urban green space, to assess an imbalance by an administrative district (Dong), and to establish the management zone of urban green spaces for the construction of an environmental city in Changwon. The spatial data of 1:5,000 digital maps, park data in Changwon, land cover by the Ministry of Environment, and IKONOS satellite images from 2003 were used for this analysis. The assessment of the imbalance of urban green spaces was analyzed with the Lorenz curve and Gini's coefficient. The establishment of the management zone was performed by network analysis of GIS. The results of this study are as follows: the urban green spaces were classified as a park green space, a natural green space, and a riparian green space. According to the results of assessment of the imbalance of green spaces, Gini's coefficient was analyzed at higher than 0.4. Thus, the spatial imbalance of urban green spaces in Changwon was evident. The management zones to solve the imbalance were established: "rich zone", "fair zone", "poor zone" and "broken zone". Therefore, the rich and fair zones which have rich green spaces must maintain the good conditions through analysis of the green network and a survey of civic attitudes. The poor and broken zones which have poor green spaces must improve quality and quantity through creation of additional green spaces, construction of an eco-industrial park, and utilization of children's parks and pocket parks.

생태계서비스란 자연생태계가 인간에게 주는 혜택을 통틀어 일컫는 용어이다. 생태계서비스를 정량화하기 위하여 다양한 모형이 개발되어 적용되고 있다. InVEST는 대표적인 생태계서비스 모형이며 그 중 서식지질 평가가 폭넓게 사용되고 있다. 우리나라에서는 국립공원을 대상으로 서식지질 평가가 실시되고 있다. 서식지질 평가를 위해서는 서식지질 초기값으로 위협인자에 대한 민감도 평가가 이뤄져야 하는데, 이는 국가 및 적용분야에 따라 판이하다. 그래서 그동안 진행된 국립공원 서식지질 평가를 바탕으로 전문가 설문(AHP)을 실시하여 서식지질 초기값인 민감도의 기준을 조정하였다. AHP실시 결과 자연초지, 경지정리가 안된 밭 등 10개 항목이 상향조정되었으며, 하천, 호소 등 8개 항목이 하향조정되어 총 18개 항목이 조정되었다. 조정된 민감도 결과를 바탕으로 도시형인 북한산국립공원과 계룡산국립공원, 사적형인 경주국립공원, 해상해안형인 한려해상국립공원 그리고 산악형인 지리산국립공원과 설악산국립공원을 대상지 서식지질 분석을 실시하였다. 분석결과 국립공원내 분포하는 시가화건조지역과 수역에 대한 부분이 서식지질 평가에 반영되었음을 알 수 있었다. 향후 이 기준을 이용하여 자연공원의 서식지질 평가가 가능할 것이다.

The purpose of this study is to suggest an improvement for the CPTED(Crime Prevention Through Environmental Design) guidelines for the urban linear park. We analysed the Changjeon-dong section of Gyeongui Line Forest Park into 12 sub-areas and evaluated CPTED design applied on the park based on analysis framework derived from 15 precedent studies by conducting on-site observations. Both surveys and in-depth interviews on users of the park were conducted and the results of analysis on the evaluation from users and the on-site observation were compared. We found that the lighting condition and the height of wall and trees at the park boundaries are very important to insure natural surveillance since the adjacent areas are easy to be hidden from passers-by and subject to invasion and threat of crime while protecting the privacy of residents on the boundary. There should be improvement on management facilities and crime prevention facilities for more safe and convenient use of the linear park and the adjacent commercial use during nighttime also need to be managed for conflicts between various type of users.

To preserve atmospheric environment of urban areas, it needs to create urban space considering air pollution sources and natural and geographical properties such as wind circulation. According to this study could examine climate and environmental characteristics of Daegu and accordingly suggest a climate map in urban environment and an "advice map" in urban planning. The urban area(area paved with asphalt and concrete) of Daegu has increased by more than five times since 1960. In addition, the analysis of thermal environment through satellite data shows that the surface temperature between a place paved with artificial structures and a farmland shows $10{\sim}20^{\circ}C$ difference during the daytime in the summer. Regarding the parks inhibiting the heat island of a city have the small area of trees, and the road paved with concrete is wide so that they hardly serve as the source of heat absorption. As Apsan is located to the south of Daegu and Palgonsan to the north and Daegu has east high west low type, mountain wind from mountains in the south and north passes a city and delivers heat and air pollutions at night. In the west of Daegue, there is the poorest environment and industrial facilities and environmental basic facilities are mostly located, so large residential complexes that are being built around the industrial facilities as if they set up a folding screen and therefore the poor environment is increasingly worse.

This study was aimed to propose the plan of creating a biotope reflecting an ecological education as well as its function as the habitats of amphibian in Namsan Urban Natural Park in Seoul. There were Cheonil mineral spring area which was located on the southern side of Namsan, wetlands which was already created on the east valley(800$m^2$) and a buffer area of the circumference(1,100$m^2$) as the biotope sites. Major fields of this study include a survey of the staus, a basic plan, a master plan; a survey of this site was focused on topography, water system, existing vegetation, wildbird, amphibian, trail; a detailed plan was focused on flow plan, planting plan, facility plan. Existing vegetation was classified into 8 types; Pinus densiflora forest, Pinus densiflora planted area, Prunus sargentii-Quercus spp. forest, Pinus rigida forest, Robinia pseudoacacia forest, artificial green space, wetlands, south beltway. There were Pinus densiflora planted area and Prunus sargentii-Quercus spp. forest as major vegetations of this site. 14 species and 33 individuals of wildbirds appeared, Rana temporaria ornativentris and Hynobius leechi were investigated in the wetlands.In particular, habitats of amphibian were divided eco-zone, buffer-zone and restore-zone, and habitats and facilities which would be suitable for the characteristics of each space were planned. As a result, environment elements of good habitats including spawn wetlands of amphibian, harbor of amphibian, water plant of wetland, wild shrubs forest, ecological landscape forest, wetland observation trail, fence of wetland protection and ramp by pebble and log were created at the site. The amphibian biotope of Namsan is rated high as an important space for conserving biodiversity. Accordingly, continuous monitoring of this biotope as a urban habitat is required as the environment changes.

The purpose of this study was to evaluate the urban park and the green spaces within the public service framework. It was investigated by identifying the priority elements as defined by the residents and to figure out the differences of residents' satisfaction for the parks in new and old downtown. This study surveyed 455 residents from 80 dong (neighborhoods) of 5 Gu(districts) in Daejon. In this study, satisfaction on the urban parks and the green spaces in the old downtown was compared with the new town area. The results were as follows: Those who lived in the new downtown areas showed higher satisfaction than those in the old downtown for the urban parks and the green spaces, as well as in all 8 other evaluation sections. Both new and old downtown residents scored high on the 'city landscape and the natural environment' and 'green spaces and facilitats' items, but scored low on 'citizen's respect' and 'acceptance of resident opinions'. The old downtown residents highly valued on easy access to the parks, while the new downtown residents focused on various activities and programs, as well as resident participation, as the parks. The variables affected the resident's satisfaction on the urban parks in old downtown areas consisted of 'information', 'diversity', 'supply decision'. Among these variables, 'diversity' had the most significant influence on the satisfaction level.

도시현상의 해석을 위해 공간정보는 필수적이다. 위치정보가 부족한 도시정보를 공간정보로 변환하기 위한 공간정보화 방법론이 꾸준히 개발되어왔다. 정형화된 주소정보나 지명 등을 이용한 Geocoding이나 이미 위치정보가 있는 공간정보와의 공간결합, 참조데이터를 활용한 수작업 형태 등이 대표적이다. 그러나 아직도 행정기관에서 작성되는 수많은 문서정보들은 비정형화된 문서형태로 인해 공간정보화의 수요가 있음에도 그동안 깊이 있게 다루어지지 못하였다. 본 연구는 자연어 처리 모델인 BERT를 활용하여 도시계획과 관련된 공개문서의 공간정보화를 진행한다. 주소가 포함된 문장 요소를 문서로부터 추출하고, 이를 정형화된 데이터로 변환하는 과정을 중점적으로 다룬다. 18년 동안의 도시계획 고시공고문을 학습 데이터로 사용하여 BERT 모델을 학습시켰으며, 모델의 하이퍼파라미터를 직접 조정하여 성능을 향상시켰다. 모델 학습 후의 테스트 결과, 도시계획시설의 유형을 분류하는 모델은 96.6%, 주소 인식 모델은 98.5%, 주소 정제 모델은 93.1%의 정확도를 보였다. 결과 데이터를 GIS 상에 맵핑하였을 때, 특정 지점의 도시계획시설에 관한 변경 이력을 효과적으로 표출할 수 있었다. 본 연구로 도시계획 문서의 공간적 맥락에 대한 깊은 이해를 제공하며, 이를 통해 이해관계자들이 더욱 효과적인 의사결정을 할 수 있게 지원하기를 기대한다.

In order to investigate the effect of air temperature reduction on an urban neighborhood park, air temperature data from five inside locations (forest, pine tree, lawn, brick and pergola) depending on surface types and three outside locations (Suwon, Maetan and Kwonsun) depending on urban forms were collected during the summer 2016 and compared. The forest location had the lowest mean air temperature amongst all locations sampled, though the mean difference between this and the other four locations in the park was relatively small ($0.2-0.5^{\circ}C$). In the daytime, the greatest mean difference between the forest location and the two locations exposed to direct beam solar radiation (brick and lawn) was $0.5-0.8^{\circ}C$ (Max. $1.6-2.1^{\circ}C$). In the nighttime, the mean difference between the forest location and the other four locations in the park was small, though differences between the forest location and locations with grass cover (pine tree and lawn) reached a maximum of $0.9-1.7^{\circ}C$. Comparing air temperature between sunny and shaded locations, the shaded locations showed a maximum of $1.5^{\circ}C$ lower temperature in the daytime and $0.7^{\circ}C$ higher in the nighttime. Comparing the air temperature of the forest location with those of the residential (Kwonsun) and apartment (Maetan) locations, the mean air temperature difference was $0.8-1.0^{\circ}C$, higher than those measured between the forest location and the other park locations. The temperatures measured in the forest location were mean $0.9-1.3^{\circ}C$ (Max. $2.0-3.9^{\circ}C$) lower in the daytime than for the residential and apartment locations and mean $0.4-1.0^{\circ}C$ (Max. $1.3-3.1^{\circ}C$) lower in the nighttime. During the hottest period of each month, the difference was greater than the mean monthly differences, with temperatures in the residential and apartment locations mean $1.0-1.6^{\circ}C$ higher than those measured in the forest location. The effect of air temperature reduction on sampling locations within the park and a relatively high thermal environment on the urban sampling locations was clearly evident in the daytime, and the shading effect of trees in the forest location must be most effective. In the nighttime, areas with a high sky view factor and surface types with high evapotranspiration potential (e.g. grass) showed the maximum air temperature reduction. In the urban areas outside the park, the low-rise building area, with a high sky view factor, showed high air temperature due to the effect of solar (shortwave) radiation during the daytime, while in the nighttime the area with high-rise buildings, and hence a low sky view factor, showed high air temperature due to the effect of terrestrial (longwave) radiation emitted by surrounding high-rise building surfaces. The effect of air temperature reduction on the park with a high thermal environment in the city was clearly evident in the daytime, and the shading effect of trees in the forest location must be most effective. In the nighttime, areas with high sky view factor and surface types (e.g., grass) with evapotranspiration effect showed maximum air temperature reduction. In the urban areas outside the park, the high sky view factor area (low-rise building area) showed high air temperature due to the effect of solar (shortwave) radiation during the daytime, but in the nighttime the low sky view factor area (high-rise building area) showed high air temperature due to the effect of terrestrial (longwave) radiation emitted surrounding high-rise building surfaces.
