  • Within the paper an approach for the automatic extraction and reconstruction of buildings in urban built-up areas base on fusion of high-resolution satellite image and LIDAR data is presented. The presented data fusion scheme is essentially motivated by the fact that image and range data are quite complementary. Raised urban objects are first segmented from the terrain surface in the LIDAR data by making use of the spectral signature derived from satellite image, afterwards building potential regions are initially detected in a hierarchical scheme. A novel 3D building reconstruction model is also presented based on the assumption that most buildings can be approximately decomposed into polyhedral patches. With the constraints of presented building model, 3D edges are used to generate the hypothesis and follow the verification processes and a subsequent logical processing of the primitive geometric patches leads to 3D reconstruction of buildings with good details of shape. The approach is applied on the test sites and shows a good performance, an evaluation is described as well in the paper.

  • In this study, various factors affect on the reconstruction of the deteriorated apartment housing complex in the Taegu-City were analyzed. The conclusions obtained in this research were summarized as follows; 1) In case of 4 to 5 storied apartment buildings, those were main objects for reconstruction. The number of the buildings and households consisting apartment complex and the total building area and the ground area were appeared as major factors. Those factors were highly correlated with the consensus of reconstruction. 2) As a maximun area of reconstruction was limited, higher existing consensus capacity and its ratio affect negatively on reconstruction of deteriorated apartments. 3) The main motivation for reconstruction is disadvantages among the members of reconstruction association were main obstacles to reconstruct the deteriorated apartment buildings. Therefore, a resoanble alternatives for reconstruction plans and administrative managements were needed.

  • This study aims to find architectural characteristic of Nam-kwan-wang-myo as known as Nam-myo, Especially focusing on difference between before and after it's reconstruction in 1899. Nam-kwan-wang-myo is a shrine for Kwan-woo who was warlord in ancient china. Belief of Kwan-Woo was introduced to Korea in Japanese invasion of 1592 and the shrine was built in 1598. Belief of Kwan-Woo diffused for the late Joseon, during the reign of Gojong, many people have faith in Kwan-Woo including the king. There was four Kwan-wang-myo around the Hanyang at that time. In 1899 a fire of unknown cause broke out at Nam-kwan-wang-myo, so the main buildings burned down. The king instructed reconstruction of the shrine even though there was in financial difficulties, it had done in the midst of a national crisis. The buildings almost restored as before. The buildings in the shrine has strong characteristics of Chinese architecture because it made by people of the Ming dynasty. Two side-by-side roofs, accumulated brick exterior are important architectural feature, but also all the buildings in the mail hall area Surrounded by the closed-connected fence is hard to find examples in Korea traditional architecture. And Nam-kwan-wang-myo just had maintained architectural characteristics including layout of buildings, shape of the each building until it's reconstruction(1899).

  • In order to obtain a 3-D urban model, an abstraction of the surface model is required. This paper describes works on the 3D reconstruction and modeling by the grouping 3D line segments extracted from the stereo matching of edges, which is derived from multiple images. The grouping is achieved by conditions of degrees and distances between lines. Building objects are determined by the junction combinations of the grouped line segments. The proposed algorithm demonstrates effective results of 3D reconstruction of buildings with 2D aerial images.

  • 우리나라의 경우 급속한 경제성장을 이룩한 1970년대 이후 도시화가 빠르게 진행되어 주택부족 문제가 발생하게 되었고, 정부의 주도로 공동주택인 아파트를 꾸준히 건설하였으며, 민간 건설업체에서도 주택 수요를 충족시키기 위해 아파트를 대단지 형태로 건설하였다. 이러한 철근콘크리트 구조물로 건축된 아파트는 세월이 경과함에 따라 여러 가지 요인에 의하여 콘크리트가 열화 됨으로서 아파트 건축물이 초기에 가진 물리적인 성능 유지하기 어렵게 되며, 시대가 변화에 따라 아파트에 요구되는 기능과 형식이 변화하게 된다. 현재 아파트를 재건축하기 위해서는 건축년도와 안전진단 결과가 재건축에 해당하여야 하며, 이러한 조건이 만족하더라도 "시 및 주거환경 정비법 시행령" 제28조에 의거 아파트 전체 토지 지분 보유자의 75%가 재건축에 동의해야 재건축 할 수 있다. 즉 현재의 관련 법규에 의하면 아파트를 비롯한 주택의 재건축에 있어서 거주하는 주민들의 생각이 매우 중요하다고 할 수 있다. 본 연구에서는 대전지역 5개구에 위치하고 있는 25년 이상된 아파트에 실제로 거주하고 있는 주민들을 대상으로 실시한 재건축과 리모델링에 대한 선호도에 대하여 조사 분석하였다. 그 결과, 25년 이상된 아파트에서 거주하는 주민들은 거주자 생활 편의 개선을 위해서 리모델링을 선호하는 것으로 조사되었으며, 재건축을 선호한 주된 요인으로는 수익성 때문인 것으로 조사되었으며, 리모델링을 선호한 주된 이유는 시간 단축인 것으로 조사되었다.

  • Kyeongbokgung succeeded in regaining its status as a royal palace after the reconstruction that began in the second year of King Gojong(1865) only to have most of its buildings taken down in the early 20th century. Fortunately, however, there is the Pukkwoldohyong(Map of North Palace), which drew out each of the buildings of Kyeongbokgung and their arrangement in details in 1907 when the royal palace lost its original appearance. And there is another plot plan of the royal palace at the Korea University Museum, which labeled it Kyeongbokgung-Baechido(Planning Map of Kyeongbokgung Palace). The map presents almost the same plan as Pukkwoldohyong in terms of making and expressive methods, being estimated to have been made in 1888 since its building arrangement doesn't show the changes made after 1890. The map also offers more information about the uses of each building than Pukkwoldohyong and matches the excavation results of the relics. Kyeongbokgung-Jeondo(Map of Kyeongbokgung Palace), which is recorded to be made during the reconstruction of the palace in the early years of King Gojong in historical materials, describes the shapes and arrangements of the buildings in a concrete and realistic fashion. The Kyeongbokgung-Baechido seems to be one of the plans made in the process of restoring and repairing buildings that were lost or destroyed in fire. The Kyeongbokgung-Baschido has the following historic values; 1) it provides dues to estimate the early state of the palace after the reconstruction during the reign of King Gojong. In fact the Sujeongjeon and Heungbokjeon show the early state of the reconstruction; 2) it contains data with which to understand the changes to the palace after 1890, around which they added Hamhwadang and Jibokjae; and 3) it offers information about the uses of the palace's buildings from 1885 to 1880 with its descriptions of the building purposes and relationships regarding the life in the palace.

  • In Korea, construction and development has been continued rapidly since the 1970s, and the reconstruction and renovation market has recently been activated to improve old buildings. Most of the environmental evaluation of reconstruction and renovation projects is focused on the use of operating energy, and It is necessary to analyze carbon emissions throughout the life cycle for a comprehensive evaluation of reconstruction and remodeling projects. Therefore, this study quantitatively predicted carbon emissions from reconstruction and renovation based on ISO 14040s through case analysis for the purpose of evaluating the carbon emissions of renovated buildings from the perspective of the whole life cycle. In additional, the amount of carbon savings of each was analyzed through comparison with existing building.

  • The purpose of this study is to conduct researches on the aspects of reconstruction and remodeling of low-rise, dilapidated apartment buildings in the provinces, using comparative methodologies, consequently coming up with the findings in the following. 1) Unlike the rebuilding projects in which the movement process tends to be made in a bulk (in a simultaneous manner), it turns out that when it comes to remodeling, it would be advisable to attempt moving the inhabitants as a group either by the size of their residence or by the building. 2) Given the peculiarities of the construction management mechanism, remodeling projects might seem disadvantageous on the part of the management on account of inadequate accumulation of information and experience. Hence, based on the impeccable assessment of the current status of the subject buildings from the phase of planning, its imperative to closely look into and take into consideration a variety of direct and/or indirect factors in advance of the implementation. 3) A series of comparative researches from the perspective of economical efficiency that remodeling projects appear profitable considering the overall costs including financial expenses, varied taxes, and so on that will be eventually brought forth during the reconstruction period, and all the more so when allowing for the consequential effects which they ought to have upon the natural and human resources, environmental and ecological condition, business potentials, etc. Amelioration to be desired on the basis of the findings above.

  • Strong wind is the main factors of wind-damage of high-rise buildings, which often creates largely economical losses and casualties. Wind pressure plays a critical role in wind effects on buildings. To obtain the high-resolution wind pressure field, it often requires massive pressure taps. In this study, two traditional methods, including bilinear and bicubic interpolation, and two deep learning techniques including Residual Networks (ResNet) and Generative Adversarial Networks (GANs), are employed to reconstruct wind pressure filed from limited pressure taps on the surface of an ideal building from TPU database. It was found that the GANs model exhibits the best performance in reconstructing the wind pressure field. Meanwhile, it was confirmed that k-means clustering based retained pressure taps as model input can significantly improve the reconstruction ability of GANs model. Finally, the generalization ability of k-means clustering based GANs model in reconstructing wind pressure field is verified by an actual engineering structure. Importantly, the k-means clustering based GANs model can achieve satisfactory reconstruction in wind pressure field under the inputs processing by k-means clustering, even the 20% of pressure taps. Therefore, it is expected to save a huge number of pressure taps under the field reconstruction and achieve timely and accurately reconstruction of wind pressure field under k-means clustering based GANs model.
