A high-rise Mixed-use building is a multi-purpose which has commercial, business and residential uses. In Korea, after the middle of 1990's, the rate of residential parts was Increased to 90%. Now, the residential parts finally bacame mainly. And residental spaces are more important than before. Residential spaces are according to variety trends such in their areas. Some companies have several interior design trend in their building. They sometimes use the interior trend when to sell their goods(apartments) in their macketing. Modern design is presented in almost dwelling-units-types. But Classic type is presented in large-units-types. Minimal design is presented in only some middle-units-type as well as in the cases of the companies having definite interior trend. Interior design trend is one another factor in dwelling spaces design.

현대인의 경우 대부분이 하루 중 80% 이상의 시간을 어떤 형태의 가정, 사무실, 공공건물, 학교, 병원, 지하시설물, 상가, 음식점, 자동차, 지하철 등의 실내공간에서 생활하고 있으며, 특히 어린이와 노약자, 병약자들의 경우 대부분의 시간을 실내에서 보내고 있는 실정에 있어 실내공기오염이 인체에 미치는 영향은 크다고 할 수 있다. 실내환경에는 대기환경과는 달리 물리적, 화학적, 생물학적으로 매우 다양한 오염물질들은 복합적인 배출원에서 기인되며 그 배출량은 물질에 따라 상당히 편차가 있을 뿐 아니라 오염물질 농도분포 역시 시간적, 공간적 특성에 따라 다양하게 나타날 수 있으며, 실내공기의 상태는 일차적으로 외부공기의 영향을 받게 되고 이차적으로는 담배연기, 스토브, 오븐, 시멘트, 건축자재, 페인트 및 벽면의 입자상 물질 등과 같은 실내오염원으로부터 영향을 받아 오염상태가 심해진다.

Up to now, most of studies on seismic analysis have been limited to analyze buildings and underground structures individually so that the interaction between them could not be analyzed effectively. Thus, in this study, a dynamic analysis was conducted for soil-structure interaction with a complex underground facility composed of a building and an adjacent underground structure constructed on a surface soil and the bed rock ground conditions. Seismic stability was analyzed based on interstory drift ratio and bending stress of structure members. As a result, an underground structure has more effect on a high-rise building than a low-rise building. However the above structures were proved to be favorable for seismic stability. On the other hand, tensile bending stresses exceeded the allowable value at the underground part of the building and the adjacent underground structure so that it turned out that the underground part could be weaker than the above part. Therefore, it is inferred that above and underground structures should be analyzed simultaneously for better prediction of their interaction behavior during seismic analyses because there exist various structures around buildings in big cities.

Recent spatial information technology has brought innovative improvement in both efficiency and accuracy. Especially, airborne LiDAR system(ALS) is one of the practical sensors to obtain 3D spatial information. Constructing reliable 3D spatial data infrastructure is world wide issue and most of the significant tasks involved with modeling manmade objects. This study aims to create a test data set for developing automatic building modeling methods by simulating point cloud data. The data simulates various roof types including gable, pyramid, dome, and combined polyhedron shapes. In this study, a robust bottom-up method to segment surface patches was proposed for generating building models automatically by determining model key points of the objects. The results show that building roofs composed of the segmented patches could be modeled by appropriate mathematical functions and the model key points. Thus, 3D digitizing man made objects could be automated for digital mapping purpose.

Recently residential-commercial buildings are being built more like residential-oriented apartments and also as deluxe residential houses targeting at the high-income bracket that is seeking for high Qualify of life. The important factors to provide a pleasant environment for residential-commercial buildings are both common space shared by occupants and the quality of service and the conveniences. These have already become prominent as important factors when choosing a residence. This research manipulates the characteristics of commonly shared space, being an important factor of amenity, in the residential-commercial buildings recently built for sale so that a reference to planning of common space in residential-commercial buildings can be provided for the future.

건물의 고도화, 복합화 되고 있는 현시대에 화재시의 인명안전을 위하여 피난 및 소화기술의 발전은 더욱 강조되어 재해대책의 기술의 발전이 필요하다. 또한 소방법의 개정으로 인하여 스프링클러를 비롯한 소방설비의 수요가 늘어날 것으로 전망되어진다. 그러나 기존의 소방설비는 많은 공간을 차지하게 되어 층간높이에 영향을 크게 미치는 단점을 가지고 있었다. 본 논문에서는 화재진압설비를 기존의 공조시스템과의 결합을 통해 설치비용의 감소와 함께 공간 절감을 꾀하기 위한 적절한 공조설비의 선택을 위한 연구를 진행하고자 한다.

Recently 3D GIS and its applications are getting attention increasingly as various ubiquitous-related techniques for 3D spaces are being developed. Although they call for quantitative measures such as accessibility, most accessibilityrelated studies are limited to 2D networks, not 3D indoor space levels. In this paper, we develop an accessibility index applicable to 3D models. We first examine the theory of Space Syntax which has been developed and used to measure the connectivity or relationships between spatial segments in urban or architectural environments. Then, we expand the principle to a more general form so it can be applied to both street and indoor space levels. We incorporate different types of impedances in moving between places including distances, turns and transfers between floors into the traditional Space Syntax that measures the spatial depths solely based on the structural forms. Finally, we illustrate the use of the proposed measure comparatively using a campus building.

With the rapid and wide-spread use of mobile communications much attention has been focussed on propagation in the urban area crowed with buildings. It is often surrounded by hills, forests, and mountains. The importance of surface scattering interference between transmitters and receivers on the rough surfaces has been interested and investigated. Therefore, a prediction method is necessary to estimate the influence of rough surfaces on microwave radio propagation. Moreover, most of the mobile communications are performed based on the digital communication system rather than the analog one. In this case, we must pay more careful attention to the signal delay caused by the phase delay due to the multi-path propagation. In this paper we have analyzed numerically scattering of electromagnetic waves from Composite structures by using FVTD (Finite Volume Time Domain) method. We consider two different types of rough surfaces such as periodic and composite structures.

This paper investigates applicability of Microsoft $Kinect^{(R)}$, RGB-depth camera, to implement a 3D image and spatial information for sensing a target. The relationship between the image of the Kinect camera and the pixel coordinate system is formulated. The calibration of the camera provides the depth and RGB information of the target. The intrinsic parameters are calculated through a checker board experiment and focal length, principal point, and distortion coefficient are obtained. The extrinsic parameters regarding the relationship between the two Kinect cameras consist of rotational matrix and translational vector. The spatial images of 2D projection space are converted to a 3D images, resulting on spatial information on the basis of the depth and RGB information. The measurement is verified through comparison with the length and location of the 2D images of the target structure.

주요 도시 지역에서 발생한 집중호우로 인하여 도시지역의 홍수 피해가 증가하고 있다. 2010, 2011년에 발생한 서울지역의 홍수로 인하여 인명과 재산피해가 발생하였으며, 2014년도에는 부산 경남지역에 발생한 집중호우로 도심지역에 홍수피해가 발생하였다. 이와 같이 증가하고 있는 도시 지역의 홍수피해 저감을 위하여 다양한 치수사업 및 홍수대책 연구가 진행되고 있지만, 일부지역에서는 여전히 침수 위험성이 상존하고 있다. 기후변화로 인하여 강우량이 증가하고 있는 상황에서 도시지역 내수 배제 능력이 변화하는 환경을 적절히 대응하지 못하여 새로운 기술 개발에 대한 필요성 증가하고 있다. 본 연구에서는 도심홍수 피해를 저감시키기 위하여 도심지 홍수의 복합적 원인을 고려한 공간해석에 필요한 실험 및 수치모의를 수행하였다. 도시 지역의 침수현상을 재현 검토하기 위해서 인공강우를 구현할 수 있는 강우 시뮬레이터를 이용하여 2010년, 2011년 도심홍수 피해가 발생한 지역의 도심지 모형을 제작하고 침수현상을 재현하였다. 인공강우 모형실험을 통하여 주요 도로망의 침수심 및 흐름전파 경향을 분석하였다. 다음으로는 도심 공간의 건물과 도로망 형태에 따라서 우수의 거동을 계측한 실험결과를 이용하여 지표수 모의 수치모형의 적용성을 검토하였다. 인공강우 실험결과와 수치모의결과를 정량적으로 비교하였으며, 각 실험결과에 의한 차이점을 분석하였다. 본 연구결과에 의하면 인공강우 시뮬레이터와 수치모의를 병행하여 도심지역 침수를 재현함으로써 도심홍수에 의한 피해를 저감 시킬 수 있는 대응기술을 발전시킬 수 있을 것으로 기대된다.
