  • The concept of bio-housing comes from the new social and culture housing trends. Previous research have shown standards on performance criteria for bio-housing. However some criteria on that research were overlapped because they were merged from various current housing assessment systems. This current research looks on the duplication of criteria which were impossible to evaluate current housing assessment, and make specialized factors for bio-housing developments. Finally the research shows the magnitude of factors for bio-housing performance criteria.

  • 도심 내에서 발생하는 음식물쓰레기와 일반 가연성쓰레기인 생활폐기물을 수거 및 집하한 후에 바이오매스로 활용하고 이를 이용하여 생성된 에너지는 주거 및 상업단지 등에 공급하는 폐기물 제로 청정도시를 구상하였다. 바이오매스 순환거점으로는 바이오에너지화 시스템을 연계한 생활폐기물 자동집하시설을 설정하였다. 바이오에너지화 시스템은 바이오가스화, 연료화, 에너지순환공정으로 구성하였다. 음식물쓰레기는 처리하면서 바이오가스화하고, 일반 가연성 쓰레기는 열분해/건조하여 연료화하며, 발생되는 바이오가스와 연료는 에너지 순환공정에서 발전기, 보일러의 연료로 사용되게 하였다. 또한, 가상의 사업 대상지구에서 음식물쓰레기 35 톤/일, 일반 가연성 쓰레기 20 톤/일로 생활폐기물 총 55 톤/일에 대한 처리 및 처분에 있어서 기존도시와 폐기물 제로 청정도시에서의 탄소저감 및 건설비를 비교하였다. 그 결과, 폐기물제로청정도시에서는 기존 도시 대비 연간 탄소배출량이 약 2.7배 저감 가능하고, 폐기물 관련 환경기초시설의 건설비도 기존도시에 비교하여 약 15%절감이 예측되었다.

  • It is essential to investigate the structure and the main characteristics of BSN (Bio-Sensor Network) platform in built smart healthcare environment while designing healthy housing facilities. For this study, WSN (Wireless Sensor Network) data transmission technologies have been employed with medical sensors, and optimal medical devices would provide various Web 2.0 services by connecting to the WiBro network. The BSN platform normally recognizes in surroundings of WBAN (Wireless Body Area Network) or WPAN (Wireless Personal Area Network), and it is possible to manage sensor nodes by utilizing SOAP (Simple Object Access Protocol) and REST (REpresentational State Transfer). In addition, the feature of SNMP (Simple Network Management Protocol) for mobile gateway is also included for being adapted to huge network structure. Finally, BSN platform will play a role as important clues for developing personal WSN service models for smart healthy housing properties.

  • It is essential to investigate the structure and the main characteristic of Home USN (Ubiquitous Sensor Network) technologies in built ubiquitous environment while designing bio-sensors. For this study, Thermistor elements and Thermopile black body have been selected to implement ubiquitous technologies for bio-sensors and wireless network such as WiBro has been used to transfer sensing data to the BSN (Bio-Sensor Network) gateway. It is certain that efficiency of ubiquitous space design is improved if main components of each specific sensor network are analyzed precisely in digital way and corresponding communication modules are prepared accordingly. Ubiquitous technology, in conclusion, has to be applied not only with systematical mechanism or electronic setting but in human-centered atmosphere as well, keeping with deep consideration for bio-housing service factors in eco-friendly surrounding.

  • It is essential to investigate the structure and the main characteristic of Home USN (Ubiquitous Sensor Network) technologies in built ubiquitous environment while designing future residential space. For this study, three different housing types have been selected to implement ubiquitous technologies for residential space; those are regular, elderly, and single residence units. It is certain that efficiency of ubiquitous home design is improved if main components of each specific housing type are analyzed precisely in digital way and design models are prepared accordingly. Ubiquitous technology, in conclusion, has to be applied not on)r with systematical mechanism or electronic setting but in human-centered atmosphere as well, keeping with deep consideration for bio-housing service factors in eco-friendly surrounding; we call this Ubiquitous Humanism.

  • 본 연구에서는 아데노신3인산의 측정을 통하여 음식물 쓰레기의 발효-소멸반응에서의 미생물이 발생 및 활성정도를 총괄할 수 있는 인자를 도출할 수 있었다. 목질바이오칩을 이용한 음식물 쓰레기의 발효-소멸에서 무게감량 및 유기물 분해율이 높아질수록 아데노신3인산의 농도가 증가하였다. 아데노신3인산은 목질바이오칩의 종류별 유기물 분해 및 무게 감량에 대한 성능 선택성 설정에 유용한 인자로 활용 기대된다.

  • This study explores the environmentally innovative and low-impact technology, a zero food waste system (ZFWS) that utilizes food waste and converts it into composts or biofuels and curtails carbon emissions. The ZFWS not just achieves food waste reductions but recycles food waste into fertilizer. Based on a fermentation-extinction technique using bio wood chips, the ZFWS was employed in a field experiment of the system installed in a large-scale apartment complex, and the performance of the system was examined. The on-site ZFWS consisted of three primary parts: 1) a food waste slot into which food waste was injected; 2) a fermentation-extinction reactor where food waste was mixed with bio wood chips made up of complex enzyme and aseptic wood chips; and 3) deodorization equipment in which an ultraviolet and ozone photolysis method was employed. The field experiment showed that food waste injected into the ZFWS was reduced by 94%. Overall microbial activity of the food waste in the fermentation-extinction reactor was measured using adenosine tri-phosphate (ATP), and the degradation rate of organic compounds, referred to as volatile solids, increased with ATP concentration. The by-products generated from ZFWS comply with the national standard for organic fertilizer.

  • The housing is a human's basic space and the comfort and the safety are the most basic conditions. According to the flow of age for Well-Being since the 21th, the suppliers and the users of apartment are making best effort now for the embossment of green environmental quality of apartment, and outstretch their hands for marketing strategic purposes in a side of indoor and outdoor environment with distinctive elements. But these supply and use are on progress competitively with the simple distinction, it is thought that indoor and outdoor environment are must be promoted according to the survey of residents' consciousness. So this study aims to provide basic materials with residents for the promotion of comfortable dwelling environment by solving the basic safety problem and also aims to survey and analyze the residents' safety consciousness in object of physical and non-physical environmental quality of indoor and outdoor of apartment by analyzing indoor air quality pollution, the feeling of being victimize caused by air pollution and safety consciousness according to physical environment elements.
