-Conclusion & Discussion
Poisson's ratio is derived by dividing the horizontal strain modulus by perpendicular strain modulus. Poisson's ratio is a characteristic value of materials, and concretes have 0.16∼0.22 of it. The Poisson's ratio from the first experiment is 0.18 and thisis comprised in the range of theory, and the value from the second experiment is 0.16 which also comes under th
is manipulated
(e.g., when we push the power-off button instead of pushing hold button)
• Quantitative errors - too little or too much manipulation of the control is made
(e.g., when the volume get higher than the volume that we want initially)
We wanted to design our MP3 player to overcome this kind of errors.

1. Introduction
‘enzyme’이라는 단어를 접했을 때 많은 사람들이 실험실에서 사용하는 것으로만 생각한다. 실제 생활과의 거리가 먼 것이라고 생각하는 경우가 많이 있다. 그러나 우리 삶의 많은 부분에 효소가 들어와 있다고 할 수 있다. 특히나 효소의 사용이 보편화 되고 많은 연구와 개발이 이루어
is their inherent ability to repair physical damage. A growing trend in biomimicry is the creation of non-living structural materials that also have the capacity to heal themselves when cut, torn or cracked. Self-healing materials which can repair damage without external human intervention could give manufactured goods longer lifetimes and reduce the demand for raw materials, as well as improving
