● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

Grafting onto
“Grafting-onto” involves the chemical reaction preformed, functionalized polymers with surfaces containing complementary functional groups
Grafting from
‘‘Grafting-from’’ involves an in situ polymerization of an initiator functionalized surface with monomer.

The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.

PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.
PHB Synthesis Pathway

So far, automobiles have been core transportation. Due to its importance to industrial development, policies were mostly automobile-centered. However, those have caused many side-effects such as traffic jam, parking space problem, air pollution, environmental degradation, and traffic accidents. We must respond to environmental changes by having a new form of tr

3000년 전 경의 고대 바빌로니아(Babylonia), 중국(China), 이집트(Egypt) 사람들 유적을 살펴보면, 그 시대에 실시된 인구조사(Cencus)에서 찾아볼 수 있다. 영어로 나라를 State라고 하는 데 상태라는 의미도 갖고 있다. 그래서 통계학을 나라의 상태를 조사하는 것이라는 의미에서 Statistics이라고 한다.
▶ 도시의 형성과정 = 문명의 형성과정
▶ 차일드(G. Child) : “문명:civilization의 발상은 곧 도시혁명”
▶ 도시의 발달 : 농경의 시작과 농업 생산의 잉여로 인하여 형성 -> 사회적 조직체계의 형성과 시장 및 교통수단의 발달로 인해 더욱 크게 성장 -> 산업혁명 이후 근대적 도시의 본격적 성장
