  • It is well known that proper encapsulation is crucial for the lifetime of organic light emitting diode (OLED) displays. With the development of increasingly better barrier coatings and perimeter seals, it has now become very desirable to be able to precisely measure the rate of water vapor and oxygen permeation through barrier coatings and perimeter sealing. This paper demonstrates a new permeation measurement method that uses tritium-containing water (HTO) as a tracer material. The theoretical detection limit of this direct method is $2.4{\times}10^{-8}g/(m^2day)$.

  • 관상동맥우회술은 인공심폐기 및 심근보호의 안정성으로 인공심폐기사용하에 시행하는 것이 보편화된방법이다. 그러나, 좌전행지 및 우관상동맥에 병소가 위치하는 경우는 인공심폐기의 사용없이 심장이 박동하는 상태에서 관상동맥우회술을 시행하는 방법도 일부에서 시행되어왔다 저자들은 좌전행지 및 대각지에 협착을보인 환자에서 인공심폐기를 사용하지 않고 성공적으로 관상동맥우회술을 시행하였기에 보고하는 바이다.

  • We assume that the existence and termination conjecture for flips holds. A complex projective manifold is said to be of almost general type if the intersection number of the canonical divisor with every very general curve is strictly positive. Let f be an algebraic fiber space from X to Y. Then the manifold X is of almost general type if every very general fiber F and the base space Y of f are of almost general type.
