Outdoor advertising signs of sity is recorgnized as the most basic element forming street scenes of city as well as establishing the citys identity in firsthand and secondhand. It has just started by commercial measure but recntly, in the rapid economical growth and diversified social structure a grent number of business have been generated so that is brings an absoluce increage of kind and quantity in outdoor advertising signs. Such quantitative increase has caused now envirenmental city problems so a more effective control of outdoor advertising signs and sophisticatided and logical design is needed. Thus, I would like to set up the direction with street scenes of city can be formed through this study. Firstly, understanding the concept, special features, and strong, weark points of street scenes of city and outdoor advertising signs. Secondly, in present sitiation analysis, studing and comparing the chracteristic of our present outdoor advertising regulations with those of Japanese regulations. Thirdly performing the reserch upon now advertising signs can be influentia in city scenes and thereafter, issuing possible problem censequantly, I would like to suggest the direction of control policy of outdoor advertising signs as following (1). Leading differentiation of each reggion for the solution of environmental and scenic problem. (2). Non-realistic advertising regulation are needed to be amended for uping changing outdoor advertising signs. (3). Advertising problems should be settleed through effectiveness of outdoor advertising signs administration. (4). The problem of advertising agenics should be leaded short term and long term plan. (5). Collection of scenic pollution should be operated for building up a scenic and community consciousness. Therefore, with these suggestion of clear direction of polish, the improvement of city scenes and regional differentiation followed by activated local autonomy system can be induced so that a more beautiful city scenes can be achiveved.

Recent research has shown that university students experience severe stress and depleted directed attention due to study, social relationships, and economic dependency. Based on the stress reduction theory and the attention restoration theory, this study aims to investigate the effects of natural landscape on university students' stress and cognitive performance through a wide array of measurements including GSR(galvanic skin responsse), IBI(interbeat interval), ZIPERS(Zucherman Inventory of Personal Reactions), and mental arithmetic test. The restorative effects of natural landscape were compared with those of urban landscape. 128 university students participated in the study, and the data of 120 students was analyzed. The results showed that natural landscape was more restorative in relieving psychological stress and in enhancing cognitive performance than urban landscape, which evidenced the restorative effects of natural landscape. Therefore, it could be proposed that natural landscaping of the university campus contributes to students' stress reduction and cognitive enhancement. But such effects were not found in the two physiological measures(both GSR and IBI). Moreover, it was analyzed that urban landscape had a more beneficial effect than natural landscape for IBI, which might resulted from the participants' characteristics and the study landscape. Specifically, the young age span of the participants(average 23.8 years old) and the very natural setting of the university where they were enrolled might lead to the conflicting results in physiological measures. Also, the urban landscape used in the study had a sense of "scope", which is one of the Kaplan and Kaplan's restorative characteristics. Based on this opinion, it was suggested that future study should investigate the impact of the landscape type and contents as well as the participants' characteristics on the restorative effects of natural landscape.

By preservation of vegetation landscape in urban park, the uniqueness and attractiveness of a city can be created and maintained. In this study, the CAD simulation of Dwangju Park was implemented, and it was proved that CAD simulation can be used to preserve the vegetation landscape and to regulate the building construction. But, when simulated short range vegetation landscape, such as the position, height and forms of trees, vegetation structure, dtc., are can be important factors. And, the method of suveying and presenting trees in CAD for efficient simulation are need to be sutdied futher.

Korea's latest quantitative urban development led to a result to lose our public properties' identity provided by urban environment, so we now have to think how to solve environmental matter of one-sided public design. Because one city's public environment is the central axis to determine its first impression and also connected with its overall value, the region's value show obvious differences by its urban scape design. Therefore we analyzed current cityscape of Tokyo's Marunouchi street and Avenue des Champs-Elys$\acute{e}$es in Paris which applied how to connect visual and physical characteristics of urban space representation to outdoor space's nature well, and tried to reconsider what is our design identity of creative cityscape.

As the city in Korea has been developed rapidly and quantitatively, land viewscape has been neglected and is being recognized as one of the important issue that we have to interest in now. But land viewscape scene has not yet constructed numerically and objectively, therefore the analysis of urban viewscape had been made inefficiently, nonsystmetically, inexactively. In this study, the quantitative analysis of urban viewscape by using digital photogrammetry and GIS was made. At the result of this study, it was showed that 3D analysis of urban viewscape using digital photogrammetry is numerical, quantitative and objective not intuitive, quantitative and subjective.

근대 사회로 진입을 시도하면서 서양의 근대 문물이 국내로 쏟아져 들어오게 되었다. 그 중 전등은 고종의 필요에 의해 빠르게 도입되면서 서울의 경관을 근대적으로 이행시켰다. 전등으로 인한 야간경관은 도시의 시공간적 변화를 모두 지니는 경관으로 근대도시를 이해하는 데 중요하다. 이 연구는 서울 최초의 근대적 야간경관의 형성 과정을 추적하고자 했다. 한국에서 전등이 가장 먼저 설치된 곳은 1887년 경복궁의 건청궁이었다. 하지만 고종이라는 특정 인물을 위해 만들어졌다는 점에서 일면 중세적인 성격을 지닌 경관이라 할 수 있다. 궁궐에서만 사용되었던 전등이 민간인에게까지 전파된 데에는 전차 부설이 중요한 역할을 한다. 당시 사람들에게 전차는 부국강병의 지표이자 개화된 사회의 상징이었다. 전차의 이용객이 늘어나게 되면서 운행시간은 22시까지 연장되었다. 이때 전차의 야간운행은 1900년 종로 보신각에 가로등을 설치하는 계기가 된다. 종로 가로등은 민간이 볼 수 는 최초의 근대적 야간경관이다. 종로 야간경관은 일반 백성들이 쉽게 볼 수 있었으며 당시 백성의 상권을 위하여 조성되었다는 점에서 진정한 의미에서 최초의 근대적 야간경관이라 할 수 있다.

Recently, there seems to besome problems in the urban visual landscape as a result of continuous economic growth and industrial development. At the same time, the public has begun to be aware of the importance of visual resources, and the necessity for visual landscape conservation and improvement. Therefore, the development of evaluative indicators for systematic visual landscape planning and design is urgent. The purpose ofthis study is to discover evaluative models and indicators for the diagnosis of urban visual landscapes. This study included the selection of 18 physical indicators(statistical data) by literature reviews, adoption of field and questionnaire surveys at 12 autonomous districts in Seoul and surrounding major mountain valleys and river streams(i.e. Mt. Nam and Han-River). The content of the questionnaire is scenic beauty. Moreover, the linear regression analysis between the scenic beauty mean scores and the physical indicator scores figure out the scenic beauty prediction model. As this study suggests, the most important indicators in urban visual landscapes are 'Greens', 'Park' and 'the number of apartment buildings(higher than 20 stories).' Based on the results, greens and parks should be priority elements to considerin urban landscape planning and design. Moreover, since the number of apartment buildings that are higher than 20 stories has a negative correlation with the scenic beauty score, it can be used as basic data for landscape planning. For the scenic beauty prediction models and evaluative indicators suggest a direction of urban management, each indicator becomes basic data for visual landscape planning and design. In following studies, if physical indicators and case studies are added, the scenic beauty prediction models and evaluative indicators could be more synthetic and systematic. Moreover, the development of physical indicators in three dimensions(3D)(i.e. results from visual district analysis, view surface analysis) could be expected to obtain more general and varied results.

문명 발전에 의해 생활공간이 더욱더 복잡해짐에 따라 현실 세계의 3차원 공간으로서의 이해가 필요해졌고, 3차원 공간을 효율적으로 관리 및 분석하기 위하여 3차원 GIS에 대한 중요성이 대두되기 시작하였다. 현재까지의 3차원 GIS는 1990년대에 들어서 3차원 가상도시의 등장으로 도시 모델의 3차원 가시화에 대해 많은 연구가 진행되어 왔다. 이러한 3차원 가상도시는 도시 관리 차원에서 도시공간의 표현, 분석, 모델링, 시뮬레이션 등을 통하여 도시정보의 체계적이고 효율적인 관리를 가능하게 한다. 3D GIS 기술의 활용 사례로는 3차원 도시 경관 분석 및 도시 계획, 3차원 시뮬레이션, 3차원 위치기반 서비스, 도시 행정 관리 등이 있다. 3차원 도시 경관 분석 및 도시 계획 활용 분야에서는 3차원 GIS를 활용하여 새롭게 건설되는 건물들이나 토지 이용 변경에 따른 경관 분석을 가상공간에서 시뮬레이션 분석함으로써 경관 변화 예측 및 적합한 경관 설계에 대한 분석을 한다. 3차원 시뮬레이션의 경우 환경오염도 분석, 최적의 입지선정, 개발 전후의 경관 차이, 각종 재난에 따른 위험도 분석, 경관과 일조량 분석 등을 미리 가상도시에 시뮬레이션 함으로서 불필요한 업무를 줄일 수 있고 발생할 수 있는 결과 값을 예상할 수 있다. 3차원 위치기반 서비스의 경우 자신의 위치를 비교적 정확히 측정함으로서 생소한 도시를 방문하거나 위치를 찾아갈 경우 최단 경로 및 최적 경로를 탐색할 수 있다. 앞으로의 3차원 GIS 기술 동향으로 유비쿼터스 환경에서의 시공간분석(Temporal GIS)과 3차원 실내공간인지 기술 개발 등으로 볼수있다. 시공간분석은 시공간 질의를 통한 공간정보의 시간에 다른 변화 계산 또는 예측된 결과를 분석할 수 있고, 시공간 분석에 사용되는 공간적, 시간적 정보의 조합은 적어도 3차원 이상의 정보를 나타내기 때문에 필요에 따라 다양한 결과를 산출 할 수 있다. 종합적으로 시공간분석은 GIS의 분석 범위를 넓혀 주며 실시간 GIS 응용시스템 개발을 위한 주요 과업이다. 3차원 실내공간정보 표현기법과 공간분석 및 공간인지 기법을 이용한 통한 유비쿼터스 환경에서의 3차원 실내공간인지 기술 개발을 통해 최근 공간정보를 기반으로 한 위치기반서비스내 u-서비스 즉, 인간 행태의 분석, 관리 및 응용을 지원하도록 한다 이는 위치기반서비스 사용자의 주변상황에 대한 인지능력을 향상시켜주고 최근 사회적 이슈가 되고 있는 U-City의 성공여부에 직접적인 영향을 미칠것이다. 이를 위해 다음과 같은 기술개발이 수행되어야 할것이다. 첫째로, 공간인지 기술을 위한 3차원 실내공간표현 방법 개발, 둘째로, 3차원 실내공간정보를 이용한 공간분석 및 공간인지 기법 개발, 마지막으로 유비쿼터스 환경에서 3차원 실내공간인지를 위한 미들웨어 개발을 통해서 공간정보의 활용을 macro-scale 공간에서 micro-scale로 확산될 것이다. 그러므로, 본 세미나를 통해서, 3차원 GIS의 활용의 보편화와 대중화를 위해서는 3차원 데이터 획득 및 처리 방법, 3차원 공간데이타베이스, 공간 분석 및 가시화에 대한 기술적 이슈들을 논하고자 한다.

Three-dimensional GIS, which provides spatial information through expression techniques of virtual reality close to the real world and the web, is one of the fields that attract a new attention. In particular, Open GIS Consortium(OGC) announced a topological relationship specification of spatial object which supports interoperability while interest in interoperability of spatial data is increasing. However, this specification is limited to two-dimensional spatial object. So this research established a topological relationship of three-dimensional spatial object in order to improve urban landscape and provide a foundation to use GIS. Based on this, this study proposes ways to visualize landscape information which is appropriate for new town's circumstances. It can be concluded that this research has a bigger meaning since it established a base of sharing information about realistic urban landscape that can be accessed regardless of place and time.
