rose, higher level of electricity application became possible to realize.

supercapacitors have a lot in common with batteries, but we can say that they are the newest form of battery.
You can charge it in a very short period of time and repeat a number of charge and discharge periods.
The energy efficiency is much higher than a battery.
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
Hybrid cars run on battery power at low speeds and switch to traditional internal-combustion at higher speeds. Since the capability of a secondary battery is not enough to replace the existing engine, it still needs to have both battery-powered motor and engine to generate enough power.
Clean Diesel
The diesel car has been recognized as the main culprit of air pollution, but people are beg

1. 이동통신의 개요
1-1 이동통신이란
무선통신이란 공간을 전송매체로 하는 통신으로 송신측에서 정보신호를 전자파에 실어서 공간에 방사하고 수신측에서는 공간을 거쳐 전송되어온 전자파를 수신하여 원래의 신호를 검출하는 방식의 통신이다. 또한 전파를 매체로 해서 통신하기 때문에 사
