10개동 1,038세대가 살고 있는 충남 천안시 두정동 대우그린아파트는 보일러의 노후화로 지난 2004년 9월 358kW급 열병합발전기 1기를 설치했다. 첫 해에 3억 8000만 원의 에너지비용을 절감하고 입주민을 위한 또 다른 에너지절감사업을 구상중인 대우그린아파트를 찾았다.

In this paper, we review an outline as premise for environmental analysis of green IT which has basic stage through the world in order to make knowledge map of green IT. We can analyze genuine environment for green IT based on this premise, and we expect that we can also use to analyse power of competition based on intellectual property after performing these environmental analysis.

This paper, reviews the characteristics of green consumers through a Focus Group Interview (FGI) method. This study shows that some remarkable changes are taking place in the lifestyles of green consumers compared with the past lifestyles of green consumers. Second, this study shows that green consumers have the correct green opinions about present environmental problems and they have a critical environmentally conscious attitude on this issue. Third, the research shows that green consumers behave environmentally (buying, use, and disposal acts) based on individual and personal standards. This study suggests (based on the research findings) methods to solve environmental problems to the government, corporations, and consumers as well as ways to increase the number of environmentally conscious consumers.

잠열축열 그린하우스 난방 시스템의 난방특성을 분석하기 위하여 이에 대한 열평형 이론을 정립하고 수치해석에 의하여 컴퓨터 시뮬레이션 모델을 개발하고자 잠열축열 그린하우스 난방 시스템의 열저항 회로망을 구성하였다. 그리고 그린하우스의 피복재, 내부 공기, 토양표면, 잠열 축열재와의 열평형 방정식을 구성하였으며, Newton-Raphson반복법을 이용하여 수치해석을 하였고, 실험 분석을 통하여 수치해의 타당성을 검증하였다. 시뮬레이션 모델을 위하여 C언어를 사용하였으며, 겨울철 (11월-2월)의 기후 조건이 유사한 여러 날을 선정하여 온도, 태양강도, 상대습도, 토양 수분함량 등을 자료로 하여 모델링을 하였다. 여기에 사용된 토양 조건은 사양토로 건조한 상태를 유지하였다. 이상과 같은 분석에 의하여 그린하우스내 경시적 공기온도 변화와 열전달 현상의 실험치와 이론분석 결과가 잘 일치하고 있음을 알 수 있었다.

Lean combustion performance of natural gas and hydrogen was compared in a spark-ignition engine. The lean combustion engine operation with natural gas was limited due to combustion instability at an excess air ratio (EAR) above 1.8. The total hydrocarbon (THC) emissions increased significantly with increasing EAR. The nitrogen oxides (NO_X) emissions were also high due to the limitation of increasing EAR. The lean combustion engine operation with hydrogen showed superior combustion stability as well as low THC and NO_X emissions, even at high EARs. However, boosting technology was required to reach the high EARs.

The aim of the study is to look at the relationships among emotional dimensions, commitment to environment, consumer typology, and quality of life. For this study, 303 students completed the questionnaires and SPSS and Amos 4 were employed. The findings are: First, positive emotion increases commitment to environment. Second, commitment to environment encourages green consumer behaviors and quasi-green consumer behaviors while it reduces non-green consumer behaviors. Third, green consumer behaviors increase quality of life while quasi-green consumer behaviors and non-green consumer behaviors do not have any influence on quality of life. Some practical implications are included.

This study analyzed that technological competition, variety and simility of Green IT fields using patents data. To achieve this, we limited range of Green IT that reduction of energy, eco-friendly technology. Therefore we conducted analysis of patents that power saving systems, light control system, smart system, cloud computing and green house/eco systems. As the result of that, power saving field was the most developed. The simililarty of power saving and cloud computing systems are very high and similiarities of light control system, green house/eco systems and smart system were very high.
