2-1-1. Principle
“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res
fatal damage in some aspects as physical, financial, and time. We have called failure.
Let take attention about that how many causes about metal failure and suggestion about them. And we will show the several examples of bolt failures that have been involved in a certain environment. Through this article we can know how to use a bolt in appropriate situation and make a more sustainable bolt.

■ Design process of Phytoremediation
Area X Depth = Volume of soil
Volume X Density = Mass of soil
3. Soil’s mass X Heavy metal’s concentration
= Total amount of heavy metal calculate
4. ③ - concern standard = Disposal amount
5. Plant’s biomass and distribution ratio
▷ Disposal amount calculate for 3years
6. ④ ÷⑤ = Design period
Partial substitution of Ba by a smaller M2+ ion
unit cell volume decreases and the phase transition temperature decreases
An insulator at room temperature becomes semiconductive after doping
trivalent donars (e.g. La, Sb, Y) substitute for the Ba2+
pentavalent donars (e.g. Sb, Nb, Ta) substitute for Ti4+.

Liposomes
Liposomes are artificially prepared vesicles made of lipid bilayer.
Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases.
Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules.
Nano-particle drug carriers
Nano-particles are colloidal particles that range in size from 10 to 1000 nm i
2. Definition of scoliosis
Scoliosis is an abnormal curving of the spine. It runs straight down your back. Everyone's spine naturally curves a tiny bit. But people with scoliosis have a spine that curves too much. The spine might look like the letter "C" or "S"
Scoliosis is typically classified as either congenital (caused by vertebral anomalies present at birth), idiopathic (cause unknow

우리는 주변일상에서 쉽게 우유 및 유제품을 접할 수 있다. 흰 우유 뿐만 아니라, 맛과 향이 첨가된 다양한 종류의 우유들과 크기와 모양에 따른 다양한 포장법들도 자주 접하고 있다.
최근 식품업계에서는 포장이 기술이라 불릴 만큼 다양한 기술들로 경쟁 중이다. 이 중에서
