  • Abeles가 특성 행렬을 이용하여 기본 이론을 확립한 이래, 광학 박막의 설계는 개인용 컴퓨터의 출현으로 다양한 방법으로 쉽게 할 수 있으며, 그 응용이 빠르게 증가하고 있다. 또한 이온빔을 이용한 증착 기술의 발전으로 덩어리에 가까운 박막을 증착하고 있으며 박막의 광학적, 기계적 특성을 향상시키고 있다. 최근에는 초고속 다용량 광정보통신, 디스플레이, 레이저, 광센서, 광자기술, 광전자 등의 발전에 따라 고품질의 박막을 제작하기 위한 기술이 발전하고 있으며, 이에 따라 합성 설계 방법과 물질의 기본적 특성을 분석하기 위한 방법도 다양하게 발전되고 있다.

  • This study was performed to investigate the effects of glycine on the development of tolerance to and physical dependence on morphine. Repeated adminstration of morphine developed tolerance and physical dependence. Glycine (100, 200 and 400 mg $kg^{-1}$ i.p.) was administered intraperitoneally to mice for 7 days once a day 30 minutes prior to the morphine (10 mg $kg^{-1}$ s.c.). (omitted)

  • Several main nuclides($^{241}Am$, $^{152}Eu$ and $^{237}Np$) in radioactive waste solution were selected and examined to mutual separation with di-(2-ethylhexyl) phosphoric acid by solvent extraction technique. $^{237}Np$ was extracted more than 99.9% adding the $H_2O_2$ that was a good reductant for the oxidation state control of $^{237}Np$. $^{241}Am$, $^{152}Eu$ and $^{237}Np$ could be fairly well separated one another during the different sequence stripping stages, but about 7~9.6% of the other nuclides were still remained for the $^{241}Am$ stripping solution. This result shows that the product of $^{152}Eu$ and $^{237}Np$ was good, but $^{241}Am$ may be needed to further purification process. It was also discussed on the cause of the third phase formation phenomenon that was found in the solvent regeneration.
