Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.

도심 지역은 인구집중, 토지 피복의 변화 및 교통량 증가 등의 인공열 배출원의 다양화 등의 요인에 의해 주변지역보다도 기온이 높은 도시 열섬(Urban Heat Island) 현상에 의해 독특한 도시기후의 특색을 보이게 된다. 일반적으로 도시 열 환경에 대한 연구는 도시 열섬의 강도나 현상을 파악하는데 집중되어 왔다. 최근 들어 도시 열섬 현상 완화 또는 개선을 위한 관심이 높아지면서 도시내에 존재하는 수면이나 녹지를 이용한 기후개선에 대한 연구가 진행되고 있다. 하천은 다양한 생물이 서식하는 공간이면서 생물의 다양성이 풍부한 생태계의 보고로 인간과 환경이 조화를 이루어 온 공간이기도 하다. 이와 같이 하천은 지역의 다양성과 특수성에 따라 가지고 있는 기능이 다양하다. 그 중 하천의 환경 기능은 많은 열용량을 축적시켜 수면의 온도상승을 적게 하여 하천의 온도는 물론 주변지역의 온도를 낮추는 역할을 하게 된다. 특히 흐르는 물은 대류와 혼합과정을 거치며 열을 운반할 수 있으므로 효율적인 축열체가 된다. 또한 하천의 물 등은 광의 투과성이 높기 때문에 표면에서는 반사되지 않고 수체 내에 열을 저장한다. 따라서 이러한 현상이 종합적으로 작용하여 도심하천은 도심지에서 높게 형성된 온도를 낮추는 냉각효과가 있다고 판단된다. 이러한 영향을 알아보기 위해 본 연구에서는 원격탐사 기법을 이용하여 도심하천이 도시 열완경 완화에 미치는 영향을 분석하였다. 분석을 위해 2009년 9월 6일 Landsat 7 ETM+ 위성영상을 이용하여 LST (Land Surface Temperature)를 추출하고, SEBAL (Surface Energy Balance Algori- thms for Land) 모델을 이용하여 지표면 열수지 성분을 추출하였다. 그 결과, 도심하천 주변의 온도가 도심지에 비해 $2{\sim}3^{\circ}C$ 정도 낮게 형성되었으며, 잠열은 주변 도심지에 비해 하천에서 높은 분포를 나타내었다. 그러나 하천 둔치나 하천 주변의 콘크리트, 아스팔트 및 나대지 등의 토지피복은 지표면 온도가 높게 형성되어 도심의 heat spot으로 작용하여 열 환경을 악화시키나 도심하천은 cool spot 작용을 하여 도심의 열을 완화하는 기능을 갖는 것으로 판단된다.

The main purpose of this paper is to analyze the influence of selection attributes of convention center on participant's satisfaction. Specially, this study is focusing on the moderating effects of city image and city attractiveness. In the dimensions of convention center selection attributes, many factors affect participant satisfaction can be assumed that. They are categorized as seven factors; main facilities, subsidiary facilities, operations management, human services, board and lodging, accessibility, and peripheral conditions. The data was collected from 260 foreigners who visited the Shanghai convention center in China. 237 respondents were analyzed via intercept survey based on self-administered questionaries. The results of this study supported the proposed conceptual framework overall. The findings indicate that first, main facilities, subsidiary facilities, human services, accessibility, and peripheral conditions affected positively participant's satisfaction. Second, the high level city image and city attractiveness have moderating effect between some selection attributes of convention center and participant's satisfaction.

홍수예보방법은 크게 기상법, 수위법, 강우-유출법으로 구분할 수 있으며, 수위법은 도시지역의 중소규모 하천유역보다는 한강, 낙동강 등과 같은 대유역의 홍수예보에 적합한 방법이다. 기상법을 통한 중소규모하천의 홍수예보는 신속성(주민대피에 필요한 예보선행시간)은 갖추고 있으나, 호우사상의 첨두 홍수량에 대한 정확성(도달하는 시간과 수위를 정확하게 예측하는 정도)은 부족하다. 반면 강우-유출법은 기상법에 비해 신속성은 떨어지나, 정확성에서는 기상법보다 신뢰할 수 있는 장점을 갖고 있다. 이에 본 연구에서는 강우정보만을 이용하여 홍수예보가 가능한 Flow Nomograph를 활용한 기상법과 실시간 강우자료와 레이더 초단기 예측강우를 연동한 강우-유출법을 실시함으로써 중소규모 도시하천의 실시간 도시홍수예보를 실시하고자 한다. 본 연구의 결과는 도시홍수예보를 통한 골든타임확보 및 피해저감에 큰 기여를 할 것으로 판단된다.

This study defined and classified no-net-loss-of-greenness (NNLG) based on the law, and then assessed the NNLG index by metropolitan cities and provinces in Korea after estimating NNLG evaluation indicators for the introduction of NNLG for health improvement of urban ecosystems. The results are as follows. First, NNLG was the comprehensive meaning that was included in the greenbelt and park greenbelt and the green area which was defined by the Act on Urban Parks, Greenbelts, etc. and the National Land Planning and Utilization Act respectively. Second, NNLG was classified as a park greenbelt which was included urban parks and greenbelts such as buffer greenbelts, scenic greenbelts, and connecting greenbelts, green areas which was included in green conservation areas, green production areas, green natural areas, and green coverage which is included forests, grasslands, and wetlands that were occupied by vegetation such as trees, shrubs, and plants. Third, NNLG index by cities and provinces was assessed based on the estimation of NNLG evaluation indicators, which included parks and greenbelt areas per capita, green areas per capita, green coverage per capita, ratio of parks and greenbelts, ratio of green areas, and ratio of green coverage. As a result, Sejong city got the highest point of NNLG index and Seoul and Daegu got lowest points of NNLG index among metropolitan cities in Korea. Chungbuk got the highest point of NNLG index and Kyonggi and Jeju got lowest points of NNLG index among provinces in Korea.

The mixed-use concept definition, this study reveals, is that the mixing three or more major types of urban uses implements for economical, social and environmental values in our urban space. With this definition the study explores Seoul's mixed-use phenomenon. The quantification method, the study uses, is the relative entropy which calculate the balance of each urban use in a certain area. The relative entropy method, also known as the LUM(land-use mix score), uses three urban-use categories which is derived from the mixed-use concept definition. Hundreds of building-use types in the building regulations are categorized and calculate the LUM of Seoul's legal-status neighborhoods. The result interpreted as the criteria of Seoul's mixed-use phenomenon and categorize mixed land-use status in a certain value: 'non mixed-use' category has a value 0.631 and below, 'unbalanced mixed-use' category has a value between 0.631 and 0.884, 'balanced mixed-use' category has a value between 0.884 and 0.991 and 'complete mixed-use' category has a value 0.991 and over.
