Abalone shell is a high strength and light weighted ceramic composite material, which is composed of $CaCO_3$ platelet and protein. Microstructure of abalone shell has a matrix structure that is similar to the bricks and mortar. The technology inspired from nature which consumes low energy at low temperature is called bioinspired technology. In this study, to make high strength and light weighted ceramic composite materials using bioinspired technology, porous green body was prepared with $Al_2O_3$ platelet. PMMA was infiltrated into the porous green body, then warm pressed to eliminate pores present in the composite. The microstructure of the composite was observed with FESEM, and the mechanical/thermal properties were measured.

Nacre is an organic-inorganic composite material; it is composed of $CaCO_3$ platelet and protein. The microstructure of nacre is a matrix that is similar to bricks and mortar. Technology inspired by nature is called biomimetic technology. In this study, to make high thermal conducting ceramic composite materials using biomimetic technology, a porous green body was prepared with BN platelets. PMMA was infiltrated into the porous green body to make a composite. The microstructure of the composite was observed with FESEM, and the thermal properties were measured. The thermal conductivity of the prepared organic-inorganic composite was 4.19 $W/m{\cdot}K$.

Today, as our industries and businesses are almost dependent on electric apparatus or on-line system, management system of electric facilities is necessary to be considered as the part of the maintenance of the building. Also, facilities of power supplies can't always provide stable power service because of various situations of blackout caused by natural disaster, construction of extension building or remodeling building. And sometimes the lack of emergency power supplies can be the reason of life and property loss. So a study of emergency power system is required. Therefore, we will research the current situation of emergency power equipment of Buildings, and analyze the importance of emergency power equipment depends on case.

Currently, the climate change and other environmental problems due to the global warming go beyond the simple dimension and change the paradigm of life and our economy. The problem is that the abnormal limate phenomena will most likely occur more frequently in the future. It will be the unexpected emergency. Highly integrated urban are will be devastated if energy supply is in the hamper. First data analysis should be to prepare and plan for emergencies. Therefore, we will research the current situation of emergency power system of buildings, and analyze the electricity consumption of buildings regarding emergency power system. Through this process, it will be selected that optimum capacity of emergency power system in Important building.
대규모 정전 시 건축물 관리자의 대응 및 비상용 예비전원설비 필요성에 관한 연구 - 대구광역시를 중심으로 -

최근 국내에서 일어난 '9 15 전국규모 정전사태'를 통해 우리나라가 대규모 정전에 대해 얼마나 무방비한 상태인지 인지하게 되었고, 본 연구는 향후 대규모 정전 시 피해를 최소화 하기 위해 설문조사를 통해 데이터를 수집하였으며, 이를 PASW 18을 활용하여 통계적 해석을 실시하였다. 연구의 결과는 향후 대규모 정전에 대비한 관리체계 연구에 활용될 것으로 기대된다.

Currently the climate change and other environmental problems due to the global warming go beyond the simple dimension and change the paradigm of life. The problem is that the abnormal climate phenomena will most likely occur more frequently in the future. So it will happen the unexpected emergency many times. Highly integrated urban area will be devastated if energy supply is in the hamper. Ensure the proper ratio of the emergency power system are reviewed to provide a basis for the energy security and system foundation in emergencies. This study investigates the principal building which will be considered relatively important in case of power cut to cities and analyzes the current architectural and fire fighting laws in relation to emergency power system. This is intended to set the appropriate emergency power system capacity according to the principal building energy consumption pattern. We calculated the demand factor to analyze the power consumption and emergency power system capacity achieved from the investigation sites. We don"t have any exclusive criteria for power facilities right now. However, we think it is necessary to set the appropriated criteria though we consider the office building total demand factor ranges from 32 to 60%.
