Old Russian Legation(1890) has been attracted public attention in terms of politics and foreign affairs than architectural style because of conditions of location and historical incident. Though it was heavily damaged during the Korean war, and only the tower has been restored, it is very important in architectural history in Korea, because it is the oldest western style brick building which is existing with the old bishop's house in Myeong-Dong. But it has been impossible to reveal exactly the original form as there has been few reliable materials(picture, drawing, document) and it's remains were nearly destroyed owing to development of the surroundings. Recently the decisive document(site outline map) was found, and new research on the architect Sabatine was studied. So I can get into close with the original form by the results. In this study, I tried to conjecture the original form of the old Russian legation(the size, style, plan and indoor space, arrangement of attached facilities) and I checked the location and structure of the room where King Gojong stayed when he took refuge, and the use of the passage in the basement.

The amount of surface chlorides of architectural structure in incoming salt environment depends on the characteristics of distribution of incoming salt in atmosphere. Therefore, many researches are being conducted on deducting the correlation between incoming salt amount attached to the surface of real structure and that of atmosphere after quantitative measurement. However, in real environment, these studies are somewhat far fetched. That is because incoming salt in atmosphere are changed by various climatic conditions and in the case of the structures surface, attached incoming salt may be carried away due to the rainfall. Therefore, this study aims to draw an improved proportional relation between the amount of sodium chloride in atmosphere and that attached to the surface of architectural structures by measuring the amount attached to each architectural material using artificial incoming salt generator that can control various climatic variables that can be caused in real environment.

In this study, material tests were performed on the masonry specimens constructed with bricks and mortar used in Korea. The specimens included two types of thickness(0.5B and 1.0B) and physical conditions (good and poor). It was shown that 1.0B specimens have 3.2~1.8 times larger shear strength than 0.5B specimens and shear strength of specimens in poor condition was 66%~38% of those in good condition. Average shear stress of masonry-infills was calculated from previous experimental studies, and relationships with failure mode, material strength of masonry, aspect ratio, and frame-to-infill strength ratio were investigated. In addition, the effects of masonry strength on the seismic performance of a masonry-infilled frame was studied using a simple example building. It can be seen that the obtained average shear stress were considerably higher than the default masonry shear strength recommended by the ASCE 41, and low values the strength of masonry does not guarantee conservative evaluation results due to the early shear failure of frame members.

Artificial lighting contributes greatly to developing civilizations. It allows daytime activities to continue throughout the dark hours of the day and thus increasing work productivity as well as allowing people to enjoy nighttime activities. In addition, artificial lighting is used to beautify landscapes, architectural monuments, and thus highlighting the social-economic development of a given place. However, excessive and improper usage of artificial lighting can lead to light pollution. Light pollution is a serious issue that is detrimental to human health. It has been linked to a number of health conditions including sleep disorder, visual discomfort as well as cancer. The effects of light pollution extend throughout the entire ecosystem, affecting both plants and animals. Furthermore, sky-glow from light pollution hinders astronomical observation. The current paper presents a study conducted on lit environment of a nightscape. The quality of the sky was measured in 144 spots using Sky Quality Meter (SQM) devices. The measured spots were chosen on the basis of land use as well as distance from the Halla Mountain.

This study is designed to suggest future development guidelines for leave-out lands in the land readjustment project area. For this purpose, physical conditions which affect living conditions were surveyed. The findings are follows. First, the living conditions in the lands are low with shortage of parking space and green area, narrow and low-performance road conditions, disordered fence and roof. Furthermore, illegal waste disposal made the condition even worse. Second, it is desirable to make separated plan for the leave-out lands because they have quite different living conditions from those of the land readjustment project area. Third, it is suggested that urban planning and architectural laws should pay attention to the leave-out lands to improve living conditions. It is also recommended that planning obligations for the leave out land should be imposed on land developers.

하수슬러지는 도시 하수처리시설이나 공단 폐수종말처리시설 등에서 배출되는 유기성 슬러지로서 높은 함수상태 (70-80%)와 중금속, 다량의 유기물 등으로부터 그 처리 및 재활용에 큰 제약이 되고 있으며, 아직까지 효과적인 방법이 없다. 이에 본 연구에서는 경제성 및 2차 환경오염 방지 차원의 보다 근본적인 하수슬러지 처리 및 자원화 기술개발의 기초연구로서, 특정 온도범위($650{\sim}800^{\circ}C$)내로 열처리하고 소정의 분말도로 조정된 소성하수슬러지의 포졸란 반응 활성도와 그 영향인자를 분석하여 콘크리트용 혼화재료로서의 활용 가능성을 검토하고자 수행되었다. 본 연구의 수산화칼슘(알칼리 활성제)을 이용한 소성하수슬러지 혼입 모르타르의 압축강도 발현특성 및 수화생성물 분석결과는 재령에 따른 소성하수슬러지의 포졸란 반응 활성을 명백히 보여주었으며, 기존 콘크리트용 혼화재인 플라이애쉬나 고로슬래그미분말과 비교해 볼 때, 콘크리트용 혼화재로서의 활용가능성을 확인할 수 있었다.

Current Architectural Facade Designs have been trending to increased glass areas resulting in increasing impact on interior lighting and daylighting. In regards to indoor environmental quality, the increase in window space has a large impact on the daylighting received which ultimately impacts the liveability of a space. Especially when considering seasons, in the summer, excessive daylighting can result in glare as well as put an increased load in conditioning the air space further reducing energy efficiency. As a result, in order to improve the sustainability performance of a building, it is important to limit the natural lighting exposure to properly meet the needs and conditions of the building occupants. One of the most representative features to limit excessive sunlight exposure, is to incorporate operable blind systems. To this end, this research has been based on simulations performance through the Radiance Program. Radiance is capable of analyzing performance of daylight and impact of sunlight. Through analysis of different slat angles and blind shapes, impact and minimization of energy usage was evaluated. Furthermore, seasonal analysis was performed in order to understand the effects of seasonal climate factors. Ultimately this research provides an analysis of operable blinds optimization and effects of blind shape, control factors and angle of shading.

우리나라 건설 현장에서는 인적요소인 건설근로자들의 경험과 행동에 따라 노동 생산성이 좌우된다. 건설현장의 노동 생산성을 향상시키기 위해서는 노동생산성을 저해시키는 잠재적인 요인들에 대한 전략적인 관리가 필요하다. 하지만 기존의 노동생산성 관리는 사전에 잠재적인 저해요인들을 도출하여 전략적으로 관리계획을 세우기보다는 현장에서 발생하는 현재적인 저해요인들만을 관리하는데 치중되어 있다. 이에 본 연구에서는 잠재적인 원인을 파악하는데 용이한 IPA를 이용하여 현장별 건설근로자의 노동생산성 저해요인을 비교분석하고자 하였으며, 근로자의 경제적인 문제에 대한 불만뿐만 아니라 근로자의 고용불안과 취약한 근로조건에 대해서 보호받고 있다고 느끼지 못하는 현실적 문제점을 파악 할 수 있었다. 이를 통해 현장관리자에게 실질적이고 현장에 적합한 관리측면의 전략적 시사점을 제시하며, 현장의 특성에 따라 노동생산성 향상의 중 장기적인 대책을 마련할 수 있을 것으로 기대된다.

정부의 온실가스 감축목표에 따라 건축물 부분은 26.9%가 할당 되었다. 신규 및 기존 주택에 대해 저에너지 지속 가능한 건축물의 변화는 과제이자 필수 불가결한 문제로 대두 되었다. 신축 건축물은 각종 제도와 규제완화로 저탄소 지속가능한 에너지 변환을 유도하고 있으나 기존건축물 670만동에 대해서는 전체 감축 목표는 나와 있는데 감축방안에 대한 기준이나 방향 제시가 부족한 것이 현실이다. 본 연구는 선정 대상 건축물을 직접 방문하여 현황을 조사하고 적용 기술요소를 반복 시뮬레이션 하여 가장 경제적이고 효과적인 녹색기술 개선책을 제시 하고자 한다.
