As the 3D Greenery system is known to improve the urban environment, it works as new alternative for eco-friendly building and warrants further study for application to the domestic field. This study aimed to apply the design components for eco-friendly composition by investigating the spatial characteristics of the 3D Greenery System reflected in interior and exterior of buildings and to analyze the organization and design elements of domestic and foreign cases. The results showed that instances of the Greenery System tended to be a large scale and high-density development in order to expand various exterior spaces. Although its early forms were often found in such public facilities as exhibition and education purpose, cases of multi-unit dwelling have been growing. Allowing apartment residents to prefer intimate space by providing various such spaces for residential units and offering independent green spaces would induce diverse residents' lifestyles rather than monotonous design. The analysis also indicated that community space composed of various outdoor spaces and atmosphere would change life patterns of multi-housing and establish a real neighborhood through social interaction. Moreover, further investigation of the design patterns of outdoor space arrangement is needed since the Greenery system actively reflects the environmental characteristics of building sites and clearly shows a tendency to utilize natural terrain and slope in building shapes.

An optical system for a stereoscopic video recorder is designed with the field of view 42$^{\circ}$ and effective diameter 22 mm. We can use it by attaching it to the front lens of any video camera or camcorder to record a stereoscopic scene. This system is a double Kepler type afocal system to make the image erect and a bi-ocular type to record and display the stereoscopic scene. The optical tube length is folded with several flat mirrors and a beam splitter to be compact. This optical system is composed of 4 groups of lenses and each group serves as a relay lens for minimizing the vignetting effect. Whole field stereoscopic scenes may be captured by perpendicularly polarized alternated recording with a chopper and two perpendicular polarizers, without any loss of light energy. The displayed images may be seen stereoscopically with polarized spectacles and are kinetic because of an afterimage effect.

디지털 방송기술이 진보함에 따라 사용자들의 실감방송에 대한 욕구도 증가하고 있다. 실감방송의 목적은 3차원 AV 기술을 통해 사용자가 마치 녹음/녹화한 현장에 있는 것과 같은 느낌을 주는 것이다. 청취자가 녹음한 환경에 있는 것과 같은 느낌을 주는 3차원 오디오 신호의 획득을 위해 더미헤드를 많이 이용한다. 인간의 머리형태를 띤 더미헤드의 특성 때문에 더미헤드를 이용하여 획득한 신호를 헤드폰을 통해 재생하는 경우 입체감을 느낄 수 있다. 하지만 더미헤드의 형태 및 크기 때문에 공공장소에서 사용하기가 어렵고, 획득한 신호를 멀티채널 신호로 변환하기가 힘들며, 재생 시 전/후방 혼동현상이 많이 발생한다. 본 논문에서는 이러한 더미헤드의 단점을 극복하기 위해 머리형태를 구체로 간략화하고, 구체 위에 다수개의 마이크를 배치함으로써 3차원 오디오를 획득하고, 후처리 과정을 통해 다양한 재생환경에 적절한 재생신호를 생성할 수 있는 3차원 오디오 획득 및 재생 시스템을 제안한다. 제안한 시스템의 성능평가를 위해 무향실에서 주관적 방향성 평가 실험을 수행한 결과, 더미헤드 기술의 단점인 전/후방 혼동현상을 현저하게 줄일 수 있었다. 본 논문에서 제안한 3차원 오디오 시스템은 3D-TV나 실감방송 통에서 입체음향 콘텐츠 획득에 이용 가능하다.

The purpose of this study was to compare and apply quantitative indices for analyzing the total green space in an urban area, targeting Guro-Gu, Seoul. The indices were classified in terms of plane, solid and urban planning. The park area per person as an index of the park green's total volume was $2.34m^2$. This clearly shows the deficiency of park area. However, it did not reflect actual green space, since undesignated forests, rivers and green spaces in the city were excluded. Green coverage area per person in terms of plane was $18.85m^2$ and was useful as an index of actual urban planting, focusing on expansion of the green space. However, the conception of total volume of park green had limitation to be recognized as a unit of area. The number of trees and green area volume per person in terms of solid was 4.1 trees and $35.8m^2$, respectively. This enabled reflection on qualitative improvement plans such as increasing the volume of trees for the high density of developed areas.

21C 현대 문명사회에서는 도시의 고밀도 및 팽창으로 인하여 도시 내 생태계가 파괴되면서 생물서식처의 환경 악화 및 엄청난 감소가 초래되었으며, 그 결과로 인하여 인간과 생물이 접촉할 수 있는 공간이 현저하게 줄어들고 있다. 또한 도시 영역의 확장을 위하여 산림 및 녹지의 감소, 녹지의 분절 및 단절화, 해안 매립 등이 계획 없이 무분별하게 진행됨으로써, 각종 동식물의 개체 수 감소 및 토양의 건조화 등이 발생하고 있으며, 그 영향으로 생물종의 다양성이 떨어지고, 도시 생태계의 교란이 심해지고 있다. 이러한 도시 생태계의 교란은 도시에 거주하고 있는 시민들의 생활의 질이 떨어지게 하고 많은 환경 문제들의 주원인이 되고 있다. 지속적이면서도 자연친화적인 도시발전을 위해서는 도시 내 자연생태계를 회복하고 생물서식공간을 종합적으로 보전하면서 복원해야 한다는 요구가 높아지고 있지만, 이를 체계적으로 이루기 위한 방법론의 부재에 시달리고 있었다. 이러한 가운데 유럽을 중심으로 생겨난 비오톱(Biotope)과 비오톱 지도화 방법이 생태계를 보전하며, 시민들에게 다양한 자연체험과 휴양 기회를 제공하고 친환경적인 도시계획을 위한 핵심적인 역할을 하는 것으로 인식되고 있다. 하지만, 기존의 비오톱 지도는 이미지 기반의 2차원 지도로 제공되고 있어, 거리 및 공간 분석에 취약하고 정보전달력이 부족하여, 익숙한 전문가가 아닌 경우 비오톱을 이해하는데 상당한 정도의 시간이 필요하였다. 이에 본 논문에서는 공간정보가 결여된 2차원 형태의 GIS 데이터를 기반으로 3차원 공간 데이터를 자동으로 생성하고, 위성영상과 DEM(Digital Elevation Model)을 이용하여 3차원 지형을 만들어 각 주제도별로 입체적인 분석이 가능하도록 하였다. 또한 동영상 녹화 기능과 3차원 객체 추가 기능을 이용하여, 자연생태계를 고려한 도시의 설계를 진행하는 경우 3차원적인 모델링을 제공함으로써 효과적이면서도 사용자의 이해도를 향상 시킬 수 있는 정보 전달력을 가질 수 있도록 설계 및 구현하였다.

The purpose of this study is to analyze the impacts of three-dimensional land cover on changing urban air temperatures and to explore some strategies of urban landscaping towards mitigation of heat build-up. This study located study spaces within a diameter of 300m around 24 Automatic Weather Stations(AWS) in Seoul, and collected data of diverse variables which could affect summer energy budgets and air temperatures. The study also selected reflecting study objectives 6 smaller-scale spaces with a diameter of 30m in Chuncheon, and measured summer air temperatures and three-dimensional land cover to compare their relationships with results from Seoul's AWS. Linear regression models derived from data of Seoul's AWS revealed that vegetation volume, greenspace area, building volume, building area, population density, and pavement area contributed to a statistically significant change in summer air temperatures. Of these variables, vegetation and building volume indicated the highest accountability for total variability of changes in the air temperatures. Multiple regression models derived from combinations of the significant variables also showed that both vegetation and building volume generated a model with the best fitness. Based on this multiple regression model, a 10% increase of vegetation volume decreased the air temperatures by approximately 0.14%, while a 10% increase of building volume raised them by 0.26%. Relationships between Chuncheon's summer air temperatures and land cover distribution for the smaller-scale spaces also disclosed that the air temperatures were negatively correlated to vegetation volume and greenspace area, while they were positively correlated to hardscape area. Similarly to the case of Seoul's AWS, the air temperatures for the smaller-scale spaces decreased by 0.32% ($0.08^{\circ}C$) as vegetation volume increased by 10%, based on the most appropriate linear model. Thus, urban landscaping for the reduction of summer air temperatures requires strategies to improve vegetation volume and simultaneously to decrease building volume. For Seoul's AWS, the impact of building volume on changing the air temperatures was about 2 times greater than that of vegetation volume. Wall and rooftop greening for shading and evapotranspiration is suggested to control atmospheric heating by three-dimensional building surfaces, enlarging vegetation volume through multilayered plantings on soil surfaces.
