● 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

Ⅰ-1. Motive and Purpose
-Ubiquitous Trend of RFID (Radio Frequency Identification) can replace the barcode system. So it has emerged as a major area of ubiquitous and has been being utilized in many uses due to the high efficiency and several benefits. So our team wants to analyze and get a deep understanding about general RFID system through existed case studies.

Ubiquitous Computing이 아니다.
2) 인간화된 인터페이스로서 눈에 보이지 않아야 한다.
3) 가상공간이 아닌 현실세계의 어디서나 컴퓨터의 사용이 가능해야 한다.
4) 사용자 상황(장소·ID·장치·시간·온도·명암·날씨 등)에 따라 서비스는 변해야 한다.

Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna. The chip is called a RFID transponder or a RFID ta
