5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
- How to send the lenses into orbit, in one piece. Since conventional rocket systems with fossil fuel are expensive and polluting, professor Angel hopes to use a coil gun. While it could take 30 years to perfect, this technology might possibly be a revolutionary breakthrough in space travel. Angel's plan is for 20 coil guns to be built around the world, buried deep in mountains. The vertical gun
4. STRUCTURE DESIGN
4.1. Wing structure
Wing structure
The wing on the plane is a part that the highest load take. The large bending moments especially act on the point near the root of wing. Also, we should consider the number of spar, rib, position, skin thickness and taper ratio.
I Beam shape
4.2. I Beam
Beam theory shows that the I-shaped section is a very efficient form f
Functionalism
-개체의 본질을 보는 것은 불가능하다고 생각함.
-대신에 개체의 구성요소간의 상호작용만을 살핌.
온갖 현상을 끊임없는 생성, 소멸의 과정으로 이해하려고 한 19세기말의 과학 방법론이다.
Design으로서의 Functionalism
- Design의 수단으로 사용되는 기능주의는 programmatic한 필요와 사용
