Kangrung is a royal tomb for King Myoungjong and his wife, Queen Jeongsun. According the record, Myoungjong died on 1567 and was buried in the present location at Gongrungdong, Nowonku, Seoul. During the 2006 repair for the Jeongjagak (memorial hall) and Bigak (tombs' house) of Kangrung, a dendrochronological analysis had been conducted. We took 79 samples, 74 from Jeongjagak and 5 from Bigak, respectively, for dating. There were three major cutting groups, i.e., 1692-1694, 1737, and 1859-1861. The first group was well matched with the date of reconstruction, which was written on the 'Sangryangmun', a formal record about building activities. The tree-ring results confirmed that the present buildings of Jeongjagak and Bigak in Kangrung were reconstructed in 1695. The second and third cutting groups indicated major repairs in Bigak.

A simplified framework for the probabilistic estimation of economic losses induced by the structural vulnerability in single-story and single-bay precast industrial buildings is presented. The simplifications introduced in the framework are oriented to the definition of an expeditious procedure adoptable by government agencies and insurance companies for preliminary risk assessment. The economic losses are evaluated considering seismic hazard, structural response, damage resulting from the structural vulnerability and only structural-vulnerability-induced e]conomic losses, i.e., structural repair or reconstruction costs (stock and flow costs) and content losses induced by structural collapse. The uncertainties associated with each step are accounted for via Monte Carlo simulations. The estimation results in a probabilistic description of the seismic risk of portal-like industrial buildings, expressed in terms of economic losses for each occurrence (i.e., seismic event) that owners (i.e., insured) and stakeholders can use to make risk management decisions. The outcome may also be useful for the definition of the insurance premiums and the evaluation of the risks and costs for the owner corresponding to the insurance industrial costs. A prototype of a precast concrete industrial building located in Mirandola, Italy, hit by the 2012 Emilia earthquake, is used as an example of the application of the procedure.

The demand for more accurate and realistic 3D urban models has been increasing more and more. Many studies have been conducted to extract 3D features from remote sensing data such as satellite images, aerial photos, and airborne laser scanning data. In this paper a technique is presented to extract and reconstruct 3D buildings in urban areas using airborne laser scanning data. Firstly all points in a building were divided into some groups by height difference. From segmented laser scanning data of irregularly distributed points we generalized and regularized building boundaries which better approximate the real boundaries. Then the roof points which are subject to the same groups were classified using pre-defined models by least squares fitting. Finally all parameters of the roof surfaces were determined and 3D building models were constructed. Some buildings with complex shapes were selected to test our presented algorithms. The results showed that proposed approach has good potential for reconstructing complex buildings in detail using only airborne laser scanning data.

To express the original texture of the concrete, exposed concrete finishing technique has been applied in many buildings. However, it is likely to cause quality problems after construction is completed. In addition, because of costs and time issues, reconstruction and maintenance works are difficult and ineffective. Therefore, step-by-step proactive quality management based on sufficient consensus among participants(client, designer, contractor) is very importatnt. This study analyzed factors causing low quality exposed concrete and quality contol points applied to 'A' headquarter construction project.

Tree-ring chronologies can be used to date historical buildings by matching them with the chronologies of living trees or previously dated samples. Tree-ring dating gives a calendar year to each tree ring and produces the felling dates of logs or woods which had been used for buildings. In Korea, several chronologies of Japanese red pine(Pinus densiflora Sieb. et Zucc., 'sonamu' in Korean), a major species for the wooden building materials, have been developed and used for dating historical buildings. In this study, Tongmyungjeon Hall of Changkyung Palace in Seoul was dated by tree rings. The present Tongmyungjeon Hall was known to be reconstructed in A.D. 1834 after burned-out in A.D. 1790. We sampled total of 122 wood samples which were replaced during the repair process in 2002-2003. Felling dates of the samples were determined by the dendrochronological crossdating method. Crossdating method employs graphic comparison of the master patterns (ring-width chronologies of known dates) with those of the sample chronologies of unknown dates. Tree-ring dates confirmed that the reconstruction of 1834 utilized second-handed timbers as well as fresh-cut ones. The felling dates of wooden floor frames were mostly A.D. 1913, indicating the 'Ondol' floors were changed to the wooden floors around 1914 when the Japanese rulers brutally destroyed the royal Korean Palaces and transformed palace buildings to their offices or exhibition halls after occupying Korea in 1910. This study proved that tree-ring dating was a useful and accurate method to identify the critical dates for the history of Korean traditional buildings.

This study is purposed on applying to certifying environmental-friendly buildings about remodeling schools as an issue recently, keeping up a worldwide resource conservation movement. Application standard is directed, comparing with systems certifying green-schools in domestic and foreign policies. The following is the primary result of this study. First, on developing systems for certifying environmental-friendly buildings about remodeling schools, characteristics like ‘the phase of certifying essential lists and the diversity of certifying lists’, ‘developing departmentally into new-building, reconstruction, remodeling, existing-building in basic data’, ‘development of certifying existing-buildings as well as new-building’ in foreign systems should be developed appropriately for Korea. Next, not only reuse of the existing facilities but better assessment through diversification of classified contents in domestic system are carried out in comparing remodeling lists. Especially the primary list that is found out commonly limited lists certifying remodeling should be developed appropriately. Impossible lists getting certification should be applied to map out a concrete standard. Lastly, the range of certification should be diversified and developed sustainable like other systems for better assessment. Adding various lists suiting for Korea and departmentalizing score of phases and items in particular, for avoiding a needless collision between certification lists, absence of them. Above of all, basic direction about certifying environmental-friendly buildings about remodeling schools should be developed the only individual instrument, not for gaining it simply as a part of the environmental policy in Korea. This study has significance on vitalization of certifying environmental-friendly buildings, which performing primary environmental-friendly education facilities, based on its advance.

우리나라에 공공도서관이 많이 없다. 그 이유는 국민들의 공공도서관에 대한 중요성 및 필요성에 대한 인식 부족과 중앙 및 지방정부의 도서관건립에 대한 인색한 투자와 함께 효과적인 공공도서관 건립정책이 없었기 때문이다. 이제 선진국과 같은 작은 도서관 건립 및 운영 정책을 펴야 한다. 지역 재개발 및 아파트 재건축 추진은 이들 지역에 작은 규모의 마을도서관을 건립할 수 있는 좋은 기회이다. 서울에 있는 J아파트는 재건축을 추진하고 있는데, 이 시점에서 새로운 위치로 옮겨가는 동사무소와 우체국을 하나의 건물로 신축하고, 이 건물 내에 공공도서관을 설치할 수 있을 것이다. 도서관을 이들 시설들과 함께 1층에 배치한다면 시너지 효과를 발생시켜 세 기관 모두에게 도움이 될 것이다. 이처럼 재개발 및 재건축 지역에 공공기관 혹은 상엽시설과 함께 복합건물 형태로 작은 도서관을 건립하는 것은 우리나라 공공도서관의 부족 문제를 해결 할 수 있는 좋은 방법이다.

최근의 장기적인 건설경기의 침체와 부동산에 관련된 각종 규제의 강화로 인하여 건설회사는 신규사업에 대한 투자를 최소화하면서 동시에 많은 이익을 창출 하고자 한다 따라서 새로운 건축물에 대한 신축 보다는 기존의 건축물에 대한 리모델링을 선호하고 있는 실정이다. 또한 리모델링은 기존의 건축물에 대한 철거와 신축이라는 방법과 비교해 보았을 경우 폐기물의 배출 및 사용 자원의 수량 등의 측면에서 보다 환경적 이라고 할 수 있다. 이에 본 연구는 주거용 건축물인 아파트를 대상으로 합리적인 리모델링의 방법을 결정하기 위해 실수요자의 요구조건을 고려한 리모델링의 방법을 제안하였다 이를 위하여 먼저 리모델링 방법의 평가과정에 대한 이론적 고찰을 실시하고 이후 사용자의 요구조건의 수렴 과정을 정리하기 위한 가치평가 기준을 마련하고 이를 이용하여 리모델링 방법에 대한 평가를 실시하도록 한다 리모델링의 방법은 그 자체가 매우 다양할 뿐만 아니라 요구조건 또한 매우 다양 하므로 평가과정에서 의사결정기법인 계층적 의사결정기법을 적용하도록 한다.
