● 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

Thus, our team decided to study about cosmetic market in China. We found that foreign companies like L’Oreal, Procter & Gamble Co and Shiseido have large portion of the China’s cosmetics market share while Korean companies have little portion of that. However, Korean beauty products also have high quality and Chinese people are favorable to Korean products. In other words, it is hard to under

Ⅰ. 골밀도측정기
골다공증을 정확하게 진단하려면 골생검이 필요하지만 환자에게 고통을 준다는 점에서 쉽게 시행할 수 없는 검사로 알려져 있다. 따라서 최근에는 골다공증을 진단하는데 골밀도 측정기에 의한 방법이 흔히 이용되고 있다. 골밀도가 골다공증의 진료에 이용될 수 있는 이유는 골밀
