This study reviewed the planning characteristics of contemporary Japanese middle school architecture on which related studies are insufficient, aiming to obtain new ideas for planning Korean middle school facilities. Fourteen case schools built after 1990s were selected and analyzed. They were divided into learning-living space and other major spaces. The planning characteristics of the case schools are summarized as follows 1) The case schools were classified into two categories, departmentalized classroom type (D type) and usual with variation type (UV type) by school system. These categories can also be the classification standard for basic architectural characteristics in learning and living space of case schools. 2) D type case schools have departmentalized classrooms, home base, media space and teacher's space for learning-living space. D type case schools are divided into 'attached-to-classroom type' and 'separate type' depending on the adjacency of the home base and departmentalized classroom. 3) UV type case schools have multipurpose space around the classroom for learning-living space and can be divided into two types, i.e., 'directly adjacent' and 'separate', depending on the connectivity to classroom of multipurpose room. 4) Specialized classrooms are designed to have the openness to the public and the own characteristics of school subjects strengthened and show the spatial differentiation with connected ancillary spaces. 5) Libraries are designed as complex zones grouped with computer labs, audio visual rooms and multipurpose halls not as a single room and as open plan not with a closed wall. 6) The gymnasium is the basic sports facility with a martial arts room and outdoor pool, which are for after-school activities as well as physical education class. 7) The terrace, balcony and outdoor stairs are frequently used architectural vocabularies as diverse outdoor spaces with a variety of functions.

The representative alignments for taking a stereo image by using a stereoscopic camera are the toed-in and the parallel alignment. In this paper, we tried to find important factors in the process that captures the stereo image by modifying parallel type 3D camera alignment to take the same object information as, for instance, when toed-in type was used. The modified parallel type 3D camera has merits in both types. As a result, three important factors are found by simulation to be inter-camera distance, field of view and convergence angle for both types. And the change of the convergence angle is known to be the most important factor at the stereo fusible area in processing. The effective ranges of these factors to simulate perfectly toed-in type by modified parallel type are strongly dependent on a user's circumstances such as mobile, official, theater and so on. Additionally, the error of the simulation is reduced when the focal length of the stereo camera is short and the convergence angle becomes smaller.

Response of buildings under seismic load is different according to fundamental period. It is provided in Korean Building Code(KBC2009) seismic response coefficient by fundamental period for seismic design of buildings. Recently, many researchers have studied on fundamental period and seismic response coefficient. However, studies on seismic design using Geographic Information System(GIS) are not sufficient. Therefore, this paper has analyzed on seismic response coefficient of buildings using ArcGIS. This paper can be evaluated efficiently for seismic analysis of structures. And this study will be used as basics of a reasonable seismic design using Geographic Information Systems(GIS).

Due to the acceleration of urbanization and advancements in technology, the importance of information related to indoor spaces has been increasing. Various scanning technologies are being developed to enable versatile utilization of the interior of buildings. In this paper, a system is proposed that utilizes 2D LIDAR for scanning, rotating, and moving LIDAR in the vertical direction to obtain a collection of 2D data, which is then aggregated to acquire 3D indoor spatial information. Finally, algorithms, including error correction, are applied to visualize the indoor structure in three dimensions and generate an output.

방수로는 홍수 피해 경감을 사용되는 구조적 대책으로 최근 국내에서 널리 계획되고 있다. 이러한 방수로는 보통 횡월류위어 등으로 대표되는 유입부 구조물을 통하여 하천 본류와 연결되지만, 평상시에도 본류의 유량을 일부 분담하는 형태로 설계되는 젖은 하도(wet channel) 형태의 방수로는 별도의 유입부 구조물을 설치하지 않고 바로 본류에 연결되는 것이 일반적이다. 유입부 구조물을 통해 연결되는 방수로의 특성은 유입부 구조물의 수리학적인 특성에 의해서 많이 좌우된다. 이에 반해 젖은 하도 형태로 본류에서 바로 분기되는 방수로는 그 특성이 방수로의 폭(W), 방수로 분류각$(\theta)$등에 의해서 많이 좌우되며, 만약 설계된 방수로의 횡단면 형상이 사다리꼴 또는 직사각형 단면을 따른다면 이러한 흐름은 "제한 영마루고 횡월류위어 흐름(restricted zero-height side weir flow)"으로 분류할 수 있다. 이러한 조건에서의 흐름은 일반적인 횡월류위어 흐름과 많이 다른 것으로 알려져 있다. 본 연구에서는 이러한 방수로 폭 및 분류각을 변화시켜 방수로 분류 조건을 다양하게 구현하여 실험을 수행하였으며, 특히 분류각 변화에 따른 유량계수의 변화를 분석, 검토하였다. 또한 측정된 방류량을 기준으로 산정된 유량계수를 기존 연구자들이 제시한 영마루고(zero-height) 횡월류위어 유량계수 산정식에 의해 산정된 결과와 비교하여 분석하였다. 분석결과 분류각이 90도인 경우 본류 프루드수의 증가에 따라 유량계수가 점차 감소하였으나, 분류각이 90도 보다 작은 경우에는 본류 프루드수가 증가함에 따라 유량계수가 점차 증가하는 것으로 나타났다. 이러한 한계를 만족시킬 입체 영상) 입체영상은 영화에서 시작되었으나, 20c후반기에 들어서면서 애니메이션 분야와 모바일, 광고 패널, 텔레비전등의 매체를 이용한 입체 영상의 개발로 인하여 특정 분야에 한정 시킬 수 없으므로 영상으로 칭한다. 입체 영상은 21c에 들어서면서 영상매체의 한 분야로 급부상하고 있다. 1900년 무렵부터 연구된 입체영화(3-Dimensional motion Picture)는 In여 년이 지난 지금 대중화를 눈앞에 두고 있다. 국내에서는 놀이 동산이나 박물관등에서 흔히 볼 수 있다. 하지만 앞으로는 HDW등의 대중화로 화질의 발전을 이룬 텔레비전 분야 등에서 실용화 될 전망이다. 국제적인 흐름과 함께 국내에서도 입체 영화에 대한 연구가 활성화 되어 영상산업의 한 주류로서 대두되고 있다. 이러한 상황에서 입체영상에 대한 이해와 콘텐츠(Contents)의 개발은 기술적인 진보에 발맞추어 준비되어야 한다. 본 논문은 이러한 기술적인 계보에 발맞춘 영상 콘텐츠 개발에 박차를 가하고자 앞으로의 발전분야에 대한 기술적인 면과 기법적인 면을 제시하여 기술만 앞서고 내용은 수입하는 수입국이기 보다는 미리 준비하여 비전문가나 타국의 기술에 선점 당하지 않는 분야로 성장할 수 있는 진보적인 영상 인들의 관심과 지속적인 연구를 독려하고자 한다.시민의 휴식 및 여가선용 공간으로 활용하기 위한 사업의 기초자료로 활용되며 이미 설계검토가 시작되었다. 본 연구결과는 유수지 및 저수지의 환경개선 사업의 선두적인 성공사례로 국내 타 지역의 유사한 사업에 있어 벤치마킹을 할 수 있는 훌륭한 사례가 될 것이다.요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백

We propose a camera system to acquire indoor stereo omni-directional images and its calibration method. These images can be utilized for indoor precise mapping and sophisticated imagebased services. The proposed system is configured with a rotating stereo line camera system, providing stereo omni-directional images appropriate to stable stereoscopy and precise derivation of object point coordinates. Based on the projection model, we derive a mathematical model for the system calibration. After performing the system calibration, we can estimate object points with an accuracy of less than ${\pm}16cm$ in indoor space. The proposed system and calibration method will be applied to indoor precise 3D modeling.

The aim of this study is to represent the residential population distribution in Seoul, Korea more precisely through the dasymetric mapping method. Dasymetric mapping can be defined as a mapping method to calculate details from truncated spatial distribution of main statistical data by using ancillary data which is spatial data related to the main data. In this research, there are two types of data used for dasymetric mapping: the population data (2010) based on a output area survey in Seoul as the main data and the building footprint data including register information as ancillary spatial data. Using the binary method, it extracts residential buildings as actual areas where residents do live in. After that, the regression method is used for calculating the weights on population density by considering the building types and their gross floor areas. Finally, it can be reproduced three-dimensional density of residential population and drew a detailed dasymetric map. As a result, this allows to extract a more realistic calculating model of population distribution and draw a more accurate map of population distribution in Seoul. Therefore, this study has an important meaning as a source which can be applied in various researches concerning regional population in the future.
