뇌 연구방법
초기 뇌 연구방식은 특수한 정신기능의 장애가 있었던 사람이 죽고 난 후 그 사람의 뇌를 조사하여 손상부위를 확인함으로써 생전의 결손기능과 뇌 영역의 관련성을 밝혀내는 사후검증 방식을 택하였다. 이러한 연구는 뇌의 기본적인 해부학적 구조를 밝히는 데 도움이 되었지만 뇌가
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

Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.
Second, the certainty of Pulmuone Waters’ profitability in the long run is proved by its financial statements. Income statements in (Figure 2) show that sales revenue of Pulmuone Waters has increased 134%. Which is from ₩34,543,000,000 in 2008 to ₩46,357,000,000 in 2010. It is a high number of figures comparing to its competitors. For instance, Jinro&Hite has increased its revenue 1
Let's see the process flow of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysis by enzymes and then fermented to ethanol through the points. The initial contract for each course are as follows.

One of Amy’s Ice Creams stand out features, besides their fabulous and daring flavors like Shiner Bock ice cream, is their employees. These creative souls seem to always be in a great mood, and have no fear flinging scoops of ice cream around the store, and catching them in cups balanced on their chins. Though some have moved on to more prosperous full-time careers, there are those employees th
