  • An infinite dam with a compound Poisson input having exponential jumps is considered. As an output policy, we adopt the $P_{\lambda}$$^{M}$ Policy. After assigning costs to the dam we obtain the long-rum average cost per unit time of operating the dam and find the optimal values of .lambda. and M which minimize the long-run average cost.t.

  • 본 논문에서는 M2M에서의 WPA 기반의 인증 매커니즘을 제안하였다. 기기 간에 인증서를 배포하고 인증서를 이용하여 하나의 기기만 인증하는 것이 아닌 통신에 참여하는 기기 모두를 인증할 수 있는 매커니즘으로서 위장공격에 대한 위험위협 요소를 방어 할 수 있는 보안을 제공한다.

  • 티타늄알콕싸이드를 이용한 티타니아 입자 제조 및 $200-240^{\circ}C$ 정도의 수열처리에 의해 티타니아 입자의 물성을 제어하였고, 이를 이용하여 염료감응형 태양전지를 제조하여 티타니아 입자의 물성에 따른 태양전지 성능변화를 고찰하였다. 얻어진 티타니아 입자의 경우 수열처리 온도가 낮을수록 입자크기는 작았고 첨가되는 산농도에 따라 결정상의 제어가 가능하였다. 또한 태양전지 제조 시 입자 크기는 어느 정도 이상이 되어야 고효율 태양전지 제조에 적합하였고, 변환 효율은 9% 이상이었다.

  • Objectives : The Comparative Study Of The Eight Extra Meridians And The Primitive Meridians Will Improve The Understanding Of The Relationship Between Meridians And The Eight Extra Meridians, Which Ultimately Will illuminate The Origins Of Meridians. Methods Books From The Pre-Han And Han Dynasty, As Well As Publications Concerning Meridians And The Eight Extra Meridians Were Utilized. Results : Pathways Of The Eight Extra Meridians And The Primitive Meridians Travel Independently Without Connection With Other Meridians, And Have No Obvious Link With The Five Vital Organs And The Six Viscera. Additionally, The Terminology Of Both Meridians Is Similar, And Travel From Bottom To Top. Conclusion : The Eight Extra Meridians Have Several Similarities With The Primitive Meridians. Therefore, The Eight Extra Meridians May Be An Important Area To Investigate In The Future.

  • In order to evaluate the characteristics and quality of various Korean alcoholic beverage, the higher alcohols profiles were analyzed by gas-chromatography. Total amount of the higher alcohols depended on the type and class of the liquors. Gaschromatographic analysis showed that the type of Gin, Rum and Vodka except for SB contain n-propanol mainly. The amount of the higher alcohols determined was proportional to the content of the originally fermented liquor in the whisky. The difference in the ratio of iso-amyl alcohol content to that of iso-butanol may be useful as a parameter in evaluating the class of the whisky.
