건물이 2층이상일때‘스팬드렐’ (Spandrel)은 그 건물외관의 주요디자인요소가 된다. 따라서 건물의 층수가 많을 수록 이 부분의 디자인은 더욱 더 중요해진다. 그렇기 때문에 오늘날과 같은 다층화의 시기에는 한건물의 개성이나 미관을 위해서 또는 도시의 아름다움을 위해서 ‘스팬드렐’의 설계-예컨대 ①춤(폭)과 길이, ②창과의 위치관계(창의 깊이),③ ‘스펜드렐’자체의 단면형, ④표면마감-는 건축가의 좋은 디자인을 요구하게 된다.

고층건물이 집중적으로 밀집돼 있는 여의도 한복판에서 유난히도 눈을 끄는 시원스러운 건물이 있다. 국회의사당앞 지하차도를 벗어나면 오른편에 우뚝 솟아있는 세련된 외관의 사학연금회관 -. 건물 정면의 주차장을 겸한 넓다란 공간은 기능면에서 뿐아니라 균형잡힌 조형미가 뛰어나 고층건물이 항용 지니는 저항감을 크게 상쇄시킨다. 사립학교 교직원들의 복지후생을 목적으로 설립된 지상21층, 지하3층의 사학연금회관의 방재시설 현황은 어떠하며 불의의 재난에 과연 어떻게 대비하고 있는가를 알아본다.

세계 태양광 시장은 실리콘 태양전지를 중심으로 기술경쟁에서 가격 경쟁의 시대로 변화되면서 중국의 저가화 공세에 의해 많은 기업들이 수익성 악화로 인해 도산하거나 위기에 처하게 되었다. 이러한 위기를 극복하기 위해 세계 각국에서는 다양한 타입의 태양전지를 개발하여 사업화를 시도하고 있다. 이러한 시도 중 하나가 투명 태양전지이다. 기존의 태양전지 패널을 설치하기 위해서는 추가적인 공간이 필요하고 건물 위에 설치했을 경우 채광과 외관이 좋지 않은 단점을 가지고 있다. 이러한 문제점을 해결하기 위해 건물의 유리창을 태양전지로 활용하는 방안이 도입되고 있다. 만약 유리창을 대신하는 투명 태양전지가 상용화 된다면 추가적인 공간이 필요하지 않고 건물의 채광이나 외관을 해치지 않아 건물의 에너지 비용을 절감하고 활용도가 높아질 것이다. 본 논문에서는 투명 태양전지의 개발 동향 및 방향에 대하여 논하고자 한다.

The investigations for mitigating wind-induced excitations of tall buildings have been carried out. The aerodynamic modification of a building shape changing the cross-section with height through tapering, which alters the flow pattern around the building, could reduce wind induced excitations of tall buildings. The fart that a tapered tall building might spread the vortex-shedding over a broad range of frequencies makes more effective for reducing acrosswind responses has been established. In this paper, to investigate the tapering effect for reducing wind-induced responses of a tapered tall building, high-frequency force-balance test was conducted. The six types of building models which have different taper ratio of 2.5%, 5%, 7.5%, 10%, 15% and one basic building model of a square cross-section were tested under the two typical boundary layers representing suburban and urban flow environment. The effect of wind direction was also considered.

In this study, the effect of obstacle aspect ratio on vortex in building canyon was numerically investigated using a computational fluid dynamics(CFD) model. The sensitivity experiments were performed in the cases of increasing building length(L) and height(H) by the width(W) of building canyon. The wind vector fields and secondary reverse vortex in building canyon were discussed in this study. For the horizontal vortex, the vortex zone increased as the building length increases, but the vectors at the middle of building canyon began to change in the case of L/W=2.5. In the case of L/W=3.0, the smaller primary vortex was presented with the secondary reverse vortex. For the vertical vortex, the vortex zone increased as the building height increases, but the direction of vectors at the bottom of building canyon began to change in the case of H/W=2.5. In the case of H/W=3.5, the smaller primary vortex was presented with the secondary reverse vortex.

The ability to extract useful information from an image, such as the human eye, is an interface technology essential for AI computer implementation. The building recognition technology has a lower recognition rate than other image recognition technologies due to the various building shapes, the ambient noise images according to the season, and the distortion by angle and distance. The computer vision based building recognition algorithms presented so far has limitations in discernment and expandability due to manual definition of building characteristics. This paper introduces the deep learning CNN (Convolutional Neural Network) model, and proposes new method to improve the recognition rate even by changes of building images caused by season, illumination, angle and perspective. This paper introduces the partial images that characterize the building, such as windows or wall images, and executes the training with whole building images. Experimental results show that the building recognition rate is improved by about 14% compared to the general CNN model.

This paper provides a method for generating flight path of Unmanned Aerial Vehicle (UAV) that is intended to be used in visual inspection of dome-type nuclear containment building. The method basically employs 3-D model to extract accurate location coordinates. Two basic route patterns that provide guide lines in defining moving locations were defined for each side wall and dome section of the containment. The route patterns support sequential capturing of images as well. In addition, several simple equations and an algorithm for calculation of the moving location on the route were developed on the basis of 3-D geometric characteristics of the containment building. A prototype computer program has been implemented to validate the proposed method, and a case study shows the method can visualize covering area in 3-D model as well.

The university building which is located in Daehak-ro where the commercial buildings are. The color of the building exterior and the signs are various to distinguish. To recognize the building exterior among the surrounding areas, it needs visual and bright color on it. The blue and white selected from the color of university identity. The core of the building is treated as a tower In vertically and white color is painted. And the rest parts of the building are treated horizontally and blue color is painted. The color of the building exterior shows the visual effects not only symbolism but attention.
