대통령 소속 국가건축정책위원회, 건축정책기본계획, 건축도시공간연구소, 공공건축가. 지금 우리 건축계를 정의하는 중요한 개념들이다. 이 모두 2007년 제정된 건축기본법에 근거한 내용으로서 당시 건설기술 건축문화선진화위원회, 건설교통부, 문화관광부의 '건축문화 선진화전략' 핵심과제였다. 그러나 '건축기본법'이 있어야 한다고 처음 주장한 사람은 김광현 서울대학교 건축학과 명예교수였다. 그가 연구책임자로서 건축기본법의 바탕을 만들었으며, 오늘의 건축계를 정의하는 건축기본법의 틀과 개념 그리고 용어의 설정도 거의 그의 구상에서 나왔다. 대한건축사협회(한명수 명예회장)와 건설기술 건축문화선진화위원회(김진애 위원장)가 이 법 제정을 위해 큰 힘을 기울였다면, 그는 이론적 기틀을 확립한 인물이다. 그는 학계에 있었지만 설계대가 제값 받기에 유독 관심이 많았다. 이유는 학생들이 사회에 나가 전문가로서 좋은 일을 할 수 있는 최대의 근거는 제대로 된 설계대가에 있다는 그의 지론 때문이었다. "학생들을 가르치는 최고의 목표는 그들이 사회에 나가 좋은 대접을 받게 하는 겁니다. 건축계에서 해야 할 가장 중요한 게 뭐냐고 지금 또 묻는다면 단언컨대 나는 제대로 된 '설계대가'라고 말할 겁니다." 김광현 명예교수는 과거 '공공발주사업에 대한 건축사의 업무범위와 대가기준'에서 '친환경건축물, 에너지효율등급' 등 추가업무에 대한 대가를 제대로 받을 수 있게 하자고 주장하고 이를 연구한 책임자이기도 했다. 그는 지금 젊은 건축사 건축교육 저변확대를 위한 '공동건축학교'를 설립해 활발히 운영 중이다. 월간 "건축사"가 국내 건축계 발전을 위해 힘써오다가 작년 2월 정년퇴임한 김광현 서울대학교 건축학과 명예교수를 3월 18일 그의 대학로 연구실에서 만났다. 그는 지난날을 회고하며 건축에 얽힌 이야기와 현재 하고 있는 일, 그리고 구상 중인 향후계획까지 다양한 이야기를 전했다.

This study is concerning on the Space Modification and Facilities Characteristics of the Busan Exported-cow Quarantine Service Station(1909) before and afrter on the limits of 1945. For on this purpose, National Archives & Records Service(DJB0002115), field survey, documents records and modern aged map were analysised by each period phases, 1909, 1924, 1946, 1951 and now so on. At results on this study is the discovery on the meaning of this placeness, Space Modification and Facilities Characteristics till now before the 120 years ago. And this place has been comprehenive meaning unique dwelling form and almost rarely existing refuge village of Korea War in Korea.

Construction work has potential risk factors in the process. Therefore, the safety management task is very important and requires continuous management. In particular, the importance of safety management in construction projects has been highlighted recently with the introduction of the act on punishment of serious disasters. In this perspective, this study intends to select and present high-risk construction types that requires safety management. The presented result is expected to present standards for systematically performing safety management of construction projects.

In this study, we conducted a study to evaluate the more accurate mechanical properties of concrete damaged by fire. In relation to this, in this study, the results of compressive strength and biaxial flexural strength were compared for concrete that received high temperature heat. As a result, both the compressive strength and the biaxial bending strength decreased as the heating temperature increased. As a result of examining the correlation between the compressive strength and the biaxial flexural strength, the biaxial flexural strength was smaller than the compressive strength.

In this study, the effects of aggregates on the properties of concrete as a study to determine the mechanical properties of high-temperature damaged concrete were examined. The samples to be reviewed are cement paste, mortar, and concrete, and the strength characteristics were reviewed after heating the compression strength and tensile strength properties. The increase in magnetic shrinkage at around 100℃ showed a significant drop in strength in mortar, which does not contain aggregates or has a small diameter, and after 300℃, concrete showed a sharp drop in strength due to the hydration and aggregation of cement.

Recently, as the use of high-performance concrete has become common, various problems related to high-performance concrete have become an issue. Among them, self-shrinkage of cement paste due to low water cement ratio is known to cause problems in the volume stability of concrete. To improve this, studies related to the mixing technology of cement-based materials and nano materials have been actively conducted. Looking at the results of prior research related to nano material mixing technology, generally, research results have been reported in which nano materials are incorporated into cement-based materials to improve material properties1). Among them, it was shown that the mechanical performance and various types of functionality of the cement composite are expressed. Among nano materials, carbon nanotubes (hereinafter referred to as CNTs) and graphenes are used in a mixture with cement-based materials. Accordingly, this study intends to compare the mechanical properties by incorporating various CNTs and graphene into cement paste.

The change of temperature and humidity in early-age concrete has a great influence on the durability of the structure. In this study, a reliable wireless sensor network system and a concrete embedded type Compressive strength prediction sensor were designed using the Arduino platform. The accuracy of the compressive strength prediction sensor was verified through a mock-up experiment, and it was confirmed that the experiment had sufficient accuracy to be used in the field environment.

Construction projects and buildings are becoming taller and larger, and the size of water tanks of production facilities and high-rise buildings is also gradually increasing. Most large water tanks apply a waterproofing layer to the water tank type concrete structure. The application of polyurea coating materials, which are excellent in water resistance, chemical resistance, physical performance, rapid hardening, and workability is gradually increasing as waterproofing and anticorrosion layer for water tank. As a result, defects such as water leakage and damage to the waterproofing layer are continuously occurring, causing production disruption, setback to users. Therefore, it is required to review suitability through performance verification of the waterproofing and anticorrosion system.

According to the domestic specification, the curing of the specimen for strength management used to determine the time of the mold deformity of the structure concrete in early spring and early autumn is cured in the field structure condition. However, when the seal curing is performed in the field, the temperature of the specimen is very low compared to the temperature of the actual structure, so the strength of the structure concrete predicted based on the strength of the specimen is much undervalued than the actual one, which causes the mold to be deformed. Therefore, this study analyzed the temperature history and compressive strength characteristics of the specimen for strength management through other sealing curing at 5℃ and concrete of the actual structure, and presented the most suitable curing method.

Since concrete is contaminated or radioactive during operation of nuclear power plants, it is the most important radioactive waste generated during the dismantling of a nuclear power plant. The amount of waste is different depending on the pollution state of each facility and the applied technology is different, so there is a big difference. We aim to reduce the amount of waste and increase the value of recyclability through technology to remove radionuclides attached to the surface. For this purpose, laser scabbling, which exfoliates the surface of concrete by irradiating a laser, and a facility system for controlling dust and dust are used in parallel. The purpose of this study is to evaluate the efficiency of laser scabbling by manufacturing simulated concrete for nuclear facilities, and to review the optimal mixing design conditions for nuclear facility structures.
