1 Introduction
We're used to take a break or go somewhere for rest. But in Korea, the "leisure" wasn't usual concept for Koreans. Before 70's, we were too busy to have leisure time. But we held the Asian Games in 1986 and Olympic Games in 1988. After that, Leisure became popular and the demand of leisure made a huge increase. And also the law of travel restriction was removed. And increasing dem
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
pump와 컬럼사이에 고분자용액을 주입하기 위한 것으로, loop로 되어 있는 valve를 이용하여 분석라인에 원하는 양의 용액을 정밀하게 주입하게 설계되어 있다. 대부분 100 L (0.1 mL) loop를 사용된다. 주입구에 0.5~1 mL 주사기를 사용하여 0.15~0.20 mL 를 주입하면, 여분의 용액은 밖으로 유출되고, 0.1 mL (100 m

Lipopolysaccharides (LPS), also known as lipoglycans,
are large molecules consisting of a lipid and a polysaccharide
joined by a covalent bond; they are found in the outer
membrane of Gram-negative bacteria, act as endotoxins and
elicit strong immune responses in animals.
LPS is the major component of the outer membrane of
Gram-negative bacteria, contributing greatly to the structu
