Ion channels ion-selective and fluctuate between open and closed states
The membrane potential in animal cells depends mainly on K⁺ leak channels and the K⁺ gradient across the plasma membrane
The resting potential decays only slowly when the Na⁺- K⁺ pump is stopped
The three-dimensional structure of a bacterial K⁺ channel shows how an ion channel can wo

1. CATIA의 개요
CATIA는 Computer-graphics Aided Three-dimensional Interactive Application의 약자로서 항공기 및 자동차부품을 비롯한 산업 전반적인 분야에서 각광을 받고 있는 CAD/CAM/CAE 통합 솔루션으로서, 1981년부터 보급되기 시작한 CATIA는 전 세계 최고 제조회사인 보잉, 클라이슬러, BMW 및 IBM 등의 산업 현장에서 사
기존 전통방식으로 제조가 불가능한 Three-dimensional cooling mold, Aircraft parts 등을 더욱 weight lightening 하는 방향, 그리고 Personalized medical parts 등 다양한 방식으로 활용할 수 있습니다. 즉, additive manufacturing technology을 이용하면 다양한 소비자의 욕구를 충족시킬 수 있는 생산이 가능하다고 생각합니다.

3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

1. Not only is it easy to lie with maps, it’s essential. A map must distort reality in order to portray a complex, three-dimensional world on a flat sheet of paper. To take a simple example, a map is a scale model, but the symbols it uses for parks, restaurants, and other places are not drawn to the same scale, which―if taken literally―would make them much bigger or smaller in reality.
