1.1 크로마토그래피(Chromatography)
크로마토그래피는 chromos(color)와 graphein(write)의 합성어, 즉 색을 통해 분석하는 것으로, 혼합물(mixture)의 분리 방법 중 하나이다. 다른 혼합물 분리 방법 중 하나인 추출(extraction)과 같은 원리로 시행되지만, 하나의 상(phase)은 다른 하나의 상이 지나가는 동안 고정
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

value, gap of hip girth and waist girth. (N: Normal type, A: Small breast and big hip, H: Big breast and small hip). These basic data for garment size specification could be usefully adapted for the apparel companies' own sizing system according to their age targets and body shapes, to achieve efficient production and better fit. It also could be applied to furniture, automobile packaging, etc.
efficiency of the process as a whole. If the tasks are tightly coupled, with many cyclic dependencies, the pipeline will stall frequently, and tasks will need to be repeated because of dependencies on tasks that follow them.
The term ‘dependency structure matrix’ refers both to a particular representation of such dependencies, and to algorithms for reorganizing the dependencies by
