대해서 건중량을 측정한 후 건중량 대 생중량 비를 산출하였다. (Korea Forest Research Institute. 2007) 하지만 [표준목2]의 경우, 잎과 가지를 모두 분리하여 측정할 시간이 부족하여, 표준목의 일부분을 sampling하여 잎과 가지의 비율을 계산, 잎과 가지를 합한 무게를 측정하여 잎과 가지의 무게를 추정하였다.
Wildlife Overview
Wildlife traditionally refers to non-domesticated
vertebrates, but has come to broadly refer to all
wild plants, animals and other organisms.
Wildlife can be found in all ecosystems.

What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial

스웨덴의 교통시스템에 사용되는 에너지는 2006년 126TWh로써 스웨덴의 에너지정책의 주요한 부분을 차지하고 있다. 특히 교통 분야는 OIL, 즉 우리의 주요 목표인 탈 석유화와 가장 밀접하다고도 볼 수 있기 때문에, 스웨덴의 지역교통을 담당하고 있는 Stockholm Lokaltrafik(이하 SL
