This study was conducted for the purpose of deriving implications by observing the changing patterns and characteristics of the farmland reduction area in urban vicinity with Gimhae city, Gyeongsangnam-do as the subject. In order to achieve this goal, we first examined the problems and possibilities of farmland reduction area in urban vicinity through a theoretical review. Additionally, the characteristics of land use and community were examined for Gimhae city, Gyeongsangnam-do. The results of the study are summarized as follows. First, for 35 years from 1981 to 2015, Gimhae decreased $50.52km^2$ of farmland, which is about 17.4 times that of Yoido, and about 69.4% of the decreased farmland area. Second, the decrease in agricultural land has been expanding to the whole of Gimhae City from 1990 to 2010, and has been continuing since 2010 around dong-area. Third, in the farmland reduction area in urban vicinity, the number of settlements increases rapidly, but the aging population also increases. Fourth, the composition of the community is getting complicated with the change of the members. Taken together, it is necessary to manage the area efficiently because rapid change is present in the farmland reduction area in urban vicinity. Based on this, the implications are summarized as follows. First, there is a change in land use due to the reduction of farmland not designated as agricultural development region. Therefore, it is necessary to supplement the farmland-conversion standard. Second, despite the fact that land use management has been carried out, there have been problems such as uncontrolled development due to the development pressure beyond institutional management, and therefore it is necessary to improve the structural defects of the pertinent legal system. Fourth, while the traditional farming activities are decreasing with the decrease of agricultural land area, the increase in farms with secondary jobs and the urban-rural interchanges organization's efforts can lead to increased visits from outsiders that seek rural tourism and experiential learning.

Like other major cities in the world, Bangkok and some other cities in Thailand are expanding rapidly. The Office of Transports and Traffic Policy and Planning had selected three cities for a study of urban change; namely, Bangkok Metropolis and vicinity ( including Nontha buri, Samut Prakan , Prathum Thani, Samut Sakhon and Nakhon Pathom), Chiang Mai and Nakhon Nayok. The main objective of the study is to monitor urban development and urban extension as well as the change of landuse from farm land to urban area during two periods by using available satellite data. LANDSAT-5 TM and SPOT-HRV panchromatic were used for the first period and LANDSAT-7 ETM+ and IRS-lD panchromatic were used for the second period with a lapsed time of 14 years. I was found that during this period Bangkok Metropolis and vicinity extended 1,222 square kilometer; Chiang Mai 68.3 square kilometer, Nakhon Nayok 5.97 square kilometer. Most landuse categories which had been changed to urban were rice paddy and mixed orchard. Some suggestion for sound urban development based on satellite data was also included.

수원 화성을 건설할 당시 용연과 화홍문 일곽의 모습을 원형경관으로 보고, 이 일대 경관의 변모과정을 추적하여 원형 복원을 위한 자료 제공 목적으로 시도된 본 연구의 결과는 다음과 같다. 용연(龍淵)은 '용연정', '용두각'이라는 이칭에서도 확인되듯이, 용두암 위에 지어진 방화수류정은 용연과 일체감을 갖는 장소정체성이 부각된 시설이다. 방화수류정에 접한 용연의 남측 호안은 용두암의 자연지형을 최대한 이용하여 경계를 삼았으며, 현재 용연의 둘레길이는 원형보다 상대적으로 짧은 반면, 용연내 중도 크기는 1970년대 복원시 이미 원형보다 확대 복원된 중도를 보완하여 재정비한 명백한 과설계(過設計)의 사례로 보인다. 또한 용연의 깊이는 조성 후 지속적인 범람 등으로 복토된 상태에서 초기의 깊이를 상정하지 않은 채 실제 깊이보다 낮게 조성되었다. 그리고 현재 약 10m가량 들여서 설치된 토수구의 원형적 모습은 유천에 맞대어 시설되었던 것으로 추정된다. 한편, 용연의 식재경관은 용두암을 제외한 외곽으로는 버드나무가 단순림으로 환식되고, 중도에는 소나무와 관목성 낙엽활엽수를 혼식한 것으로 보인다. 조사대상 일원의 도입 식물 중에는 화성 건설 이후에 국내에 도입된 수종이 식재되고 있으며, 대부분 유락과 볼거리 제공을 목적으로 한 식재로 일관하고 있다. 또한 일대 성곽에는 일제 강점기인 1920년대만 하더러도 노송이 무리지어 심겨진 모습이 발견되나, 그 이후 도시개발과 한국전쟁의 여파로 조사지역에서 자취를 감추었고, 1980년대 이후 식재사업등 복원과정을 통해 재현되고 있으나 그 식재량은 원형경관에 비해 매우 미미한 실정이다. 이와 같은 결과를 바탕으로 용연과 화홍문 일곽 원형 경관의 진정한 복원을 위해서는 첫째, 용연 지반은 암반이 노출되도록 깊이 준설하고, 용두암과 화홍문 방향의 남서측으로 확장하여 불규칙한 반달 형태로 재조성하는 한편 중도의 크기는 대폭 축소하여야 할 것으로 본다. 둘째, 소나무나 용두암에 자생하는 식물상을 제외하면 대부분의 수종은 경승지로서의 관상 등 볼거리 제공의 목적으로 도입된 비 향토수종으로 처리되고 있음에 따라 화성 축성시 활용된 소나무를 중심으로 한 향토수종 위주로 대체되어야 할 것이다. 특히, 중도에 식재된 능수버들은 용연 외곽으로 처리하고, 중도는 소나무를 주목(主木)으로, 단풍나무나 화목의 낙엽활엽수 등을 첨목(添木)으로 하는 수종 전환이 요구된다. 셋째, 방화수류정에서 북암문 주변에 군식된 리기다소나무와 화홍문 인근에 식재된 스트로브잣나무 등의 외래종은 배격되어야 할 것이다.

In urban area, thermal pollution associated with heat island phenomena is generally regarded to make urban life uncomfortable. To overcome this urban thermal pollution problem, urban planning with consideration of urban climate, represented by the concept of urban ventilation lane, is widely practiced in many countries. In this study, the prevailing wind ventilation lane of a local winds in Daegu during the warm climate season was investigated by using surface wind data and RAMS(Reasonal Atmospheric Model System) simulation. The domain of interest is the vicinity of Daegu metropolitan city(about 900 $km^{2})$ and its horizontal scale is about 30km. The simulations were conducted under the synoptic condition of late spring with the weak gradient wind and mostly clear sky. From the numerical simulations, the following two major conclusions were obtained: (1)The major wind passages of the local circulation wind generated by radiative cooling over the mountains(Mt. Palgong and Mt. Ap) are found. The winds blow down along the valley axis over the eastern part of the Daegu area as a gravity flow during nighttime. (2)After that time, the winds blow toward the western part of Daegu through the city center. As the result, the higher temperature region appears over the western part of Daegu metropolitan area.

The purpose of this study was to compare the differences of the ecological attributes in the two types of urban park at Suwon and Goyang city. 'Directly linked park' is forests and rivers in the vicinity, it is capable of re-supply of the species and 'Isolated park' is forests and rivers apart, it is a difficult re-supply of the species. The result of assessment of the ecological attributes in the two types of urban park was analyzed as the percentage of 'Forest zone' was high, but the percentage of 'Area of permeable pavement' and 'Bush area' was low. 'The planting structure' was mostly 1-layer structure(47%) and 'Foreign tree species' is high by half the proportion. 'Age classes' were a 2-3age classes level, and 'Water body' could barely. Thus, ecological attributes degree was very low. In addition, results of investigation whether the difference of ecological attributes degree between the two types of urban park, also statistically analyzed that there is no difference. Therefore, when establishing the composition of the future plans of the city park, to take full account of the ecological situation in the surrounding parkland, and identify the ecological potential with the parkland. Next, it should be designed and planned of the park that fully utilizing the potential of this ecological attributes.

The Dongjung Au-Ag-Cu mine area was seriously contaminated with As and heavy metals-Cd, Cu, Hg, Mn, Pb and Zn etc. Those elements were highly accumulated in plants grown at farmland as well as farmland soil. Stream waters and groundwater which has been used as drinking water around the mine site contain high levels of heavy metals, especially As. As a result of human health risk assessment using EHS(Extraction of Heavy metals in Stomach and Small intestine) test for bioaccessible contents of heavy metals, there is a potential of cancer and adverse effects on human health for the residents of the mine area.

The Land Use Suitability Assessment System was recently introduced by the $\ulcorner$Act on Planning and Utilization of the National Territory$\lrcorner$ to use, manage, and develop the national territory, which integrated the National Land Use and Management Act and the Urban Planning Act. It provides a guideline for classifying land use into 5 classes according to locational characteristics, usability, and developmental conditions of land in the vicinity. The database is constructed with LMIS cadastral data, posted land price data, and data of related agencies such as the Korea Forest Service, the Ministry of Environment, and the Korea Water Resources Corporation etc. After the database construction, individual parcels are analysed by steps and classified into 3 sub areas - conservation, agriculture, and development using GIS. In this paper we evaluate land use suitability for individual parcels by constructing the Land Use Suitability Assessment System for Jinju city. Therefore, we suggest that this system provides vital data in the urban management planning process.

In order to use sea breezes to counter the heat island phenomena, i.e. to promote urban ventilation, it is necessary to clarify the effect of building morphology and height on large-scale wind fields. In this study, the sea breeze in the vicinity of the Kanto Plain in Japan is simulated using a mesoscale meteorological model incorporating an urban canopy model, and the inland penetration of sea breezes is accurately reproduced. Additionally, a mean kinetic energy balance within a domain (Control Volume; CV) moving along the sea breeze is analysed. From the results, it is clarified that the sea breeze is interrupted by the resistance and turbulence caused by buildings at the centre of Tokyo. The interruption effect is increased in accordance with the height of these buildings. On the other hand, adverse pressure gradients interrupt in the internal region.
