  • The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who lack enough cartilage to be harvested in addition to possessing a weak cartilage framework. In this paper, the methods for overcoming the drawbacks of the septal extension graft, such as instability, a fixed tip, and insufficiency of cartilage, are presented, and the applications of each method for greater satisfaction with surgical outcomes are also discussed.

  • 본 논문에서는 부하변동에 대해 강인한 제어기를 구현하기 위해 PI제어기에 feedforward 외란상쇄관측기를 부가하여 구현하였다. 이로 인해 외란 변동 등의 상황에서 보다 안정적인 동작을 할 수 있도록 제안하였다. 이를 입증하기 위하여 Matlab으로 시스템의 안정도에 대해 시뮬레이션을 수행하였고, 5[Hp] 유도전동기에 대해 실험을 수행하여 제안한 시스템의 유용성을 확인하여 보았다.

  • This paper presents concrete pattern recognition method to identify the strength of concrete by evidence accumulation with multiple parameters based on artificial intelligence techniques. At first, zero-crossing(ZCR), mean frequency(MEANF), median frequency(MEDF) and autoregressive model coefficient(ARC) are extracted as feature parameters from ultrasonic signal of concrete. Pattern recognition is carried out through the evidence accumulation procedure using distance measured with reference parameters. A fuzzy mapping function is designed to transform the distances for the application of the evidence accumulation method. Results are presented to support the feasibility of the suggested approach for concrete pattern recognition.
