This paper proposes a semi-automatic image-based approach for 3-dimensional (3D) modeling of buildings along streets. Image-based urban 3D modeling techniques are typically based on the use of aerial and ground-level images. The aerial image of the relevant area is extracted from publically available sources in Google Maps by stitching together different patches of the map. Panoramic images are common for ground-level recording because they have advantages for 3D modeling. A panoramic video recorder is used in the proposed approach for recording sequences of ground-level spherical panoramic images. The proposed approach has two advantages. First, detected camera trajectories are more accurate and stable (compared to methods using multi-view planar images only) due to the use of spherical panoramic images. Second, we extract the texture of a facade of a building from a single panoramic image. Thus, there is no need to deal with color blending problems that typically occur when using overlapping textures.

X-SAR images taken on the coastal waters of Hwanghe province in Korea during SIR-C/X-SAR campaign in April and October 1994 are analysed. The SAR images show the peculiar signatures like nail marks, curved long string, and vortex streets patterns and they all seem to be produced by strong interactions between the topography in the coastal waters and tidal currents. The nail mark signatures are located at the same position of small scaled sand banks and the curved line patterns are almost identical to the outer boundary of large sand banks. Based on the tidal record, all the three images are taken at the almost same phase of tidal cycles, which are close to the low tide. It seems that bottom shapes are more strongly appeared on the SAR images when the tidal currents are slow. The front between two different current velocities caused by the flows along the steep boundaries of sandbanks is also the main factors imprinting the bottom features to the sea surface SAR images

접든성통제는 고속도로에 있어서 교통사고 감소의 가장 효과적인 수단들 중의 하나로 인식되어져왔다. 이러한 접근통제의 새로운 적용으로서 접근성관리는 과도한 투자 없이 일반도로상에서 교통사고를 감소시키는데 활용되고 있다. 이 연구의 목적은 도시간선도로상에 있어서 접근성관리와 교통사고와의 관계를 교통사고비용의 측면에서 분석하는 것이다. 이를 위해, 이 연구는 미국 텍사스주 대도시 지역내 중앙분리간선도로의 교통사고자료를 다중회귀모형을 이용하여 분석하였다. 이 연구는 자료분석의 결과 다음과 같은 사실을 발견할 수 있었다. 첫째, 접근성관리는 도시간선도로의 교통사고비용과 밀접한 관계를 가지고 있었다. 둘째, 이러한 접근성관리와 교통사고비용과의 관계는 도로의 교통상황과 도로변 토지이용상태에 따라 다양하게 나타났다. 셋째, 대체로 접근성관리와 관련된 요인이 교통상황 및 토지이용상태에 관련된 요인보다 더 교통사고비용과 밀접한 관계를 보였다. 마지막으로, 교통사고비용을 설명하는데 있어 가장 중용한 접근성 관리 요인은 외부접근로의 간격으로 나타났다.

This essay examines how the figure of Liberty has been refashioned in the streets of post-apartheid South Africa, addressing three public art works installed in Johannesburg over the past decade: Reshada Crouse's oil painting Passive Resistance, Marlene Dumas' tapestry The Benefit of the Doubt and William Kentridge's and Gerhard Marx's sculpture Firewalker. Even as these monumental works all reprise Delacroix's Liberty on the Barricades-an icon of the city street and its revolutionary barricades-so too this trio of Liberties have become mere phantoms of their vaunted archetype. Haunted specters, they quarrel with the mythologized chimera of Liberty, taking issue with the fraught tradition of pinning regime change onto the body of the female nude. Drawing instead on South African histories of women's resistance, in which female nudity has been repeatedly marshaled as a form of dissent, the Liberties circling Johannesburg hybridize their European template with local traditions of female political opposition to colonial and postcolonial male authority.

This study is to research the plane form of representative and comparatively well preserved the Eastern Orthodox church that is located in the old streets of Istanbul among the church built in the 6th century to the 12th century A.D. and arrange the organic nature of plane at the christian church of the times, the characteristics of the Eastern Orthodox church followed by religion ideology. Also it is required continuously to classify and arrange the building type about the historic remains of christian church in the suburbs of Aegean sea by means of the times, region, ideeology.

The purpose of this study is examine the characteristics of public open space in the office buildings located in urban commercial strip, in terms of its relationships to street, to building, and to order surrounding facilities. Theoretical basis of this research is that public outdoor spaces are to be the intermediate territory set between streets and a buildings. 5 commercial buildings in Seoul are selected as sample cases and they were closely analyzed in a comparative manner. Based on this comparison, several planning guidelines are suggested for the activation of the space, mainly in terms of the location of public open space in relation to street, the design techniques and devises reflecting the purpose of the space, and territorial arrangement and furniture layout, and the patterns of relationship to surrounding space and facilities.

There are many attempts to make more comfortable amenity in city districts and streets to provide a soundscape design. And the sound which reflects the culture and peculiarity of characterized the street must be preserved. Thus these attempts are recognized as another noise control to give the suitable environmental sound, not to reduce noise level. This study aims to analyze the behavior of the pedestrian and sound environment of the street sound, by measuring the sound level for the Insa-Dong Traditional Culture street. As the results, it is advisable to use the natural water sound dominating the district and to provide the staying spot to watch the event to be held. The results of this study could be used as fundamental data to recover the image of Insa-Dong Traditional Culture street to consider design concept of soundscape.

Street Fashion plays an important role as an indication of new trends staring point for Young people who are fashion-conscious sensitive to changes in fashion. This study aims at: (1) comparing street fashion trends of young women in Korea and Italy by analyzing the characteristics of young people's fashion in Seoul and Milan between the seasons of Autumn in 2001 to Summer 2002 ; (2) understanding the way young women create ´self-image´ through the clothes they wear on the streets. Finally, 1 expect this study to become a useful source of data for a more detailed analysis of the overall trend of young people's fashion between the East and West.

The fluid force reduction of a square prism having fences on the corner was studied by the measuring the drag and lift acting on the prism and by the visualization experiment of the flow around the prism. The height of the fence was 10% of the square width and the range of Reynolds number considered was from $Re=0.9{\times}104$ to $Re=2.1{\times}104$. The drag of the prism was reduced about 6.8% and the amplitude of the lift was reduced by attaching two normal fences on the rear corners of the prism. In this case, the separated flow at the front corners was reattached on the upper and lower sides of the prism and the vortex streets at the wake region were appeared more slowly than that of the prototype prism.

This paper presents an algorithm for tracking lanes on the road based on corner detection techniques. The proposed algorithm shows high accuracy regardless of lane divider types, eg, solid line, dashed line, etc, and thus is of advantage to city streets and local roads where various types of lane dividers are used. A set of experiments was conducted on real roads with various types of lane dividers and results show an extract ratio over 87% in average.
