동영상에서 워터마크를 삽입하는 경우 압축 영역에서 수행하는 것이 유리할 경우가 있다. 그러나, 압축 영역에서의 워터마크 삽입은 심각한 화질 저하를 가져올 수 있다. 본 논문에서는 MPEG-2 압축 방식에서 DCT 계수에 워터마크를 삽입하는 경우의 화질 저하에 대한 실험 결과를 제시 하고자 한다.

The performance of insulate materials gets worse with stress time in power system and because this causes lowering of function and accidents in equipment, development and performance improvement of excellent insulate materials are needed to make stable system. In this paper, to study the influence of degradation in XLPE, inner semiconducting layer and outer semiconducting layer, we studied dielectric characteristics at temperature $25{\sim}100[^{\circ}C]$ and frequency $20{\sim}1[MHz]$ and volume resistivity at temperature $25{\sim}100^{\circ}C$, voltage.
