As there are a lot of differences in the public building construction cost depending on the construction scale of actual construction cost system, a lot of problems occur in the estimation of the cost. So, the development of a predictive model depending on the construction scale shall be used in a way that it is applied to the case selectively and differently. This study drew a cost estimating model through a regression analysis. For this, 42 construction sites which were ordered during 2011 to 2012 by Public Procurement Service data were selected as a historical data. Based on the application of the model to new construction and the verification of its effect, the reasonable model for estimating the construction cost has been suggested.

This paper is to clarify on the characteristics of the Haeeumwonji and the Main Palace of the Goryo Dynasty. The architectural techniques and construction methods such as embankment, stylobate, stairway, foundation stone, and pave are similar to those of the Haeeumwonji and the Main Palace of the Goryo Dynasty. In order to express the hierarchy of the area and building, the materials, techniques, and forms of the embankment, stylobate, stairway, foundation stone and pave were used differently. The paving of the floor of the main building and area is also an active expression of the hierarchy and status of the building area and the building through the use of building materials, techniques and forms. This result confirms the support of Goryeo royal family and the upper class for the construction of Haeeumwonji, which is recorded in the historical documents. And it also shows that the architectural techniques and processing method of the same period were shared in the capital and provinces, which is an important clue that proves that the capital-centered architectural technology has spread to the provinces. It is expected that additional research will be needed on the characteristics of the period of 12th century architecture technique in which Haeeumwonji was built.

The former administration office building of Kyeong-seong-bu(京城府) was a building converted from the Japanese residency-general's of Kyeong-seong(京城理事廳) which was originally built as the Japanese consulate in Joseon(日本領事館). It was too worn and too small as a Kyeong-seong-bu administration office even with several annexes. Kyeong-seong-bu tried to build a new big administration office building at the vacant north side of the same site, which was closely faced to the rotary in front of the Bank of Joseon(朝鮮銀行前廣場). But this trial was ended in vain due to insufficient budget. Therefore Kyeong-seong-bu built a new administration office building in another site and moved to it in 1926 with debts. For paying for the debts Kyeong-seong-bu sold the former site after partitioning with new roads through it. As a result the nature of the former site and its surroundings was changed. This study traces the changes and inquires how the authorities in the colonial Joseon and various commercial powers of Kyeong-seong-bu behaved for their own interests in the meantime. It makes use of the historical records and documentary literatures between early 1910s and early 1930s.

The research objective of this thesis aims to utilize the history and culture of cities as resources and to solve the problems of modern urban environment which can produce non-personality in the age of globalization. This study deals the Sustainable Urbanism and Architectural System in the Historical city ; First, Historic resources and its spatial characteristics. Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders. In order to keep the order, rehabilitation, reuse, remodeling of urban space should be managed by various participations which concerned with the city and urban architecture. That can be say systematic approach for the sustainable environment.

If cultural Heritageis located in the downtown, conservation areas was developed or is being developed In most cases Therefore, in this case, the relative height of the building during construction than the regulatory limit is reasonable, is emerging need to be objectified. This study was utilizes GIS analysis techniques for 'View Corridor' and building height standards were determined. First, 'View Corridor' set and building height restrictions for the analysis of urban environmental factors were analyzed in. In particular, the topography and urban planning, and existing buildings, including the distribution of the physical urban environment, with detailed analysis on the major historical and cultural assets with a combination of a review of the impact factor for the formation of the urban landscape recognize the scope has been expanded. Second, the key selection criteria for View point largely focused on cultural Heritageand the surrounding communicative point of view and, consequently, connectivity, and symbolism, accessibility, analysis, factors such as Prospect, setting the standards by applying a detailed assessment of each item the main view point were derived. Third, the derived key View point on the terrain and landscape characteristics simulation analysis carried out by considering together the main axis, and this suggests a reasonable height for the proposed standards.

The work of constructing apartment housing involves various fields of industry that are linked to each other, and is based on a design document prepared by multiple technicians and architects. Consequently, design errors, material flaws or faulty construction works can cause defects, which sometimes overlap with each other. Construction companies should repair any defects found in a completed building within a specified period of time, and to do this, should establish a business plan by efficiently predicting the cost of defect repair. As it is very difficult for companies to accurately predict the occurrence of defects, historical performance data is used as a base. For domestic apartment housing units, data on the cost of defect repair is insufficient, so there are hardly any methods that can be used to make precise predictions. Therefore, the intent of this study is to develop a model that can predict the cost of defect repair by supply type and area, based on historical performance data with ten years worth of post-completion.

Architecture is the historical record of a society. Residential culture is one of the cultures, and includes all the living and customs of people living in the current society. In particular, the Native residence has the research value of changing the living culture because it contains the lives of farmers. The residential culture of the Korean-chinese people contains the poor, agricultural, and immigrant life that began as a livelihood. Therefore, residential culture is an important part of the Korean-chinese culture. However, due to population movement and urbanization, the deepening and aging of the rural community caused the destruction of the residential culture, and the residentials that had been vacant for many years were destroyed, and a large number of risky residential reconstructions are underway. At the point of progress from a voluntary personal building culture to a public building culture built by the government, a study on Renovation of dilapidated Building and a more reasonable residential reform plan is needed. Our housing culture should not only improve the living environment of current life, but also inherit the housing culture contained in history.

High-rise buildings are equipped with TMD (Tuned Mass Damper), a vibration control device that ensure the stability and usability of the building. In this study, the seismic response control performance was evaluated by selecting the design variables of the TMD based on the installation location of the twisted irregular building. To this end, we selected analysis models of 60, 80, and 100 floors with a twist angle of 1 degree per floor, and performed time history analysis by applying historical seismic loads and resonant harmonic loads. The total mass ratio of TMDs was set to 1.0%, and the distributed installation locations of TMDs were selected through mode analysis. The analysis results showed that the top-floor displacement responses of all analysis models increased, but the maximum story drift ratio decreased. In order to secure the seismic response control performance by distributed installation of TMDs in twisted irregular buildings, it is judged that the mass ratio distribution of TMDs will act as a key variable.
