도심 도로변의 대기질은 주변의 고층 건물로 인한 거리 협곡으로 인하여 도시의 대기질에서 가장 빈번하게 기준을 초과하는 지역이다. 대부분의 대도시에서 고층 빌딩으로 구성된 도심 거리 협곡(urban street canyon)의 자동차에서 배출되는 대기오염물질은 운전자, 보행자, 도로변 작업자, 자동차 승객 등의 건강에 직접적으로 영향을 미칠 수 있다. 자동차 대기오염물질은 지표면에서 발생되기 때문에 거리 협곡은 배출원 인근의 대기오염물질 확산에 중요한 영향을 준다. 우선적으로, 거리 협곡은 협곡 상공에서 수직적인 혼합을 유도하게 된다. 둘째로, 거리 협곡의 형성은 협곡의 지형적 또는 물리적 경계 내의 오염물질을 정체시키게 되어, 협곡 상공으로 공기가 자유롭게 이동하여 오염물질을 수송하는 것을 지체시키는 경향이 있다.

The purpose of this study is to clarify locational characteristics and the road systems of existing 22 old settlements in Cheongju downtown of Korea. These old settlements are classified largely into two types by geographical feature; Hill type located in ridge and Valley type in the valley from the ridge. The Hill type is further categorized into San-rock located on ridge and Gogae located on hillside, and the Valley type into closed large and small valley, that is, Daegok and Sogok by the shape and size of the valley. The road systems are classified into outer road, approaching road, inner road, and side road. In San-rock type villages, Inner road is changed side roads by new arterial road, and new ones become inner road. The outer road are almost cut off, but side roads maintain. In the case of the Gogae type, main road becomes inner road, maintain old hierarchical road, and in other cases, villages are formed around side roads derived from main road, and outer road and inner road are cut off. Among the Valley type, Daegok type maintains old hierarchical road, while for Sogok type, outer roads are cut off, and new roads are outer road.

The purpose of this study is to clarify the transitional process of spatial configuration of 'Topdong Yangdalmal'; One of the existing 22 old settlements in cheongju city. The results are as follows. 1) Side roads are derived from Inner road until 1970, so large-scale lots are subdivided small-scale lots. The houses are mostly in 1970s and 1980s. The existing old houses are 11, their orientation are East South, and the entrance gives on side road. The orientation, court yard, and entrance of the houses nearby side roads keep ongoing, in spite of alteration and extension. Especially, Entrance is changed by the new arterial roads and subdivided lots, but, the houses nearby side roads are continued as in the past. 2) The newly built houses in 1970's are 20, and it's arrangements are equal to existing old one. The orientation of houses after 1980's is the same in 1970's. But, the entrance is changed by subdivided lots, and the size of the court yard are reduced or disappeared. In other hand, the houses as the same size of the existing houses, and Storyincrease continue court yard as in the past. Therefore, the houses which are nearby inner road, and increase story, are continued, in spite of the newly built one.

The purpose of this study is to review and evaluate the proper planning for 2030 Incheon Urban Parks & Green Space Master Plan. Some of the plans are aimed at multiple small districts within the city's old town, as local governments are planned to be sub-subsidized by Incheon Metropolitan City. However, these plans have become simple plans for each district and therefore find it difficult to collect from the perspective of the using system of the residents who are directly used. First, the construction of the urban park and green space network requires the construction of a service using system that can be felt by the users. Second, the basic idea of each district planned as the detailed strategy of the master plan should be planned through consultation with nearby the district. Third, specific targets and directions for the urban park and green space plan through the urban development project are needed.

최근 국지성 호우 등 홍수방어 시설의 설계빈도를 초과하는 강우 발생으로 홍수피해가 증가하고 있다. 그 중 도시지역의 내수침수 피해는 전체 피해액의 50%를 넘는다. 그러나 우수관거의 노후화 및 통수능 부족으로 우수의 즉각적인 배출이 이루어지지 않아 침수피해가 증가하고 있다. 침수피해의 주요 원인 중 저지대 지역 및 우수관거의 통수능력 부족이 침수피해의 가장 큰 원인을 차지한다. 따라서 도심지의 경우 내수침수로 인한 피해가 증가하고 있는 점을 감안하면 배수관거와 연계한 저류시스템 구축으로 침수 빈발 지역의 치수 능력 향상을 통하여 경제적 피해를 저감시킬 수 있다. 저류시스템은 현장 노면수 저류를 위한 측구 저류조와 저류조 운영 시스템을 의미하며, 저류조 운영 시스템 모델에 대한 연구를 수행하였다. 측구 저류조 운영 시스템 구축을 위해서 현장 센싱(Sensing)데이터와 연계할 수 있는 정보체계 및 운영 시스템 모델이 필요하다. 이에 센서를 활용한 도심지 측구 저류조 운영 시스템 모델을 제시한다. 먼저 센서의 구성은 측구 저류조 내의 협소한 공간과 전원공급, 방진·방수 문제를 해결할 수 있도록 구성되어야 하며, 무전원 근거리 이동통신기술(RFID)을 적용하여 측구 저류조 운영 시스템 수집서버와 통신하여 센싱 데이터를 저장한다. 데이터는 근거리 RFID 리더기가 측구 저류조로부터 센싱 정보를 수신하여 통신모듈에 수신한 저류조 개폐도어 열림과 닫힘 시그널(signal), RFID의 고유 ID 등을 전달 받아 운영 시스템 내의 RFID 이력 DB(Database)에 기록한다. 기록된 정보는 각각 RFID 일련번호, 기록 시간, 동적센서 시그널 값 등이 저장되어 각각의 측구 저류조의 상태를 확인할 수 있어야 한다. 저류량 산정을 위해서 GIS기반의 하수도 시설물 속성 데이터를 포함하는 운영 시스템을 구성해야 한다. 운영 시스템은 수집된 센서정보를 시계열 단위로 분석하고 위치정보 기준으로 측구 저류조 내의 총 저류량 산출에 필요한 기초정보를 제공하며 결과를 표출한다. 따라서 하수도 시설물의 속성정보를 포함하여 측구 저류조 및 센서의 속성정보 정의가 필요하며, 공간정보 파일(Shape File)을 적용하여 GIS 운영 시스템을 구축하여야 한다. 운영 시스템은 저류조 만관상태와 총 저류량을 산출하여 침수위험 알림을 제공할 수 있으며, 예상 강우에 따른 도심지 피해를 역으로 예측하여 강우사상 빈도에 따른 측구 저류조 체적을 결정할 수 있다.
