1. 서론
의식주는 인간의 가장 기본적인 생활이다. 그중에서도 식생활이 차지하는 중요성은 매우 높다. 특히, ‘국’과 ‘찌개’의 문화를 가지고 있는 한국사회의 식생활에서 냄비는 없어서는 안 될 중요한 역할을 한다. 광택이 나며 녹이 슬지 않고 깨끗이 씻기 쉬우며 오래 사용할 수 있다는 특성
light chains: 40 V x 5 J = 200
light chains: 30 V x 4 J = 120
H chains: 40 VH x 27 DH x 6JH = 6,480
320 L chains x 6,480 H chains = 2.1 x 106
Junctional diversity (addition or deletion of nucleotides at recombination sites, especially of H chain), estimated to add 3x107 fold to overall diversity.

ion-dipole and dipole-dipole interactions
- hydrophobic interaction (water-hating)
non-polar molecules do not dissolve in water
- amphpathic : a single molecule has two portion, polar and non-polar

Interactions coming from electrostatic, hydration, steric and van der Waals forces, changes in the surface hydrophobicity or conformational changes of the adsorbed molecules play an important role in the final bending.[1],[2] The easiest and most extended model to study the surface stress produced on cantilevers is based on the work of G.G Stoney in 1909. Looking for higher accuracy, some works h

chain. These basic structural properties play a major role in determining bulk physical properties of the polymer, which describe how the polymer behaves as a continuous macroscopic material. Chemical properties, at the nano-scale, describe how the chains interact through various physical forces. At the macro-scale, they describe how the bulk polymer interacts with other chemicals and solvents.
