Abstract: A method for solving hidden preferred-user problems in a communication system using the cognitive radio technique is provided to prevent the signal interference by establishing a safety area in which a hidden preferred-user is not generated, and then guiding the transmission radius of a CR node inside the safety area. A transmission CR node searches a neighbor node in a safety area(401) and then grasps whether the neighbor node exists in a safety area(402). If the neighbor node does not exist, the transmission CR node connects to a preset common control channel(404) and then establishes a connection with the neighbor node after controlling the transmission radius(405).

Abstract: 본 발명은 전기방사를 이용한 원적외선 방출, 항균 및 소취 특성을 갖는 나노섬유 부직포의 제조방법에 관한 것으로서, 더욱 상세하게는 특정농도의 폴리우레탄 용액에, 유기용매에 용해되지 않는 기능성 무기입자 즉, 원적외선 방출입자, 항균 무기입자 및 소취 무기입자를 일정비율로 첨가한 전기방사 용액을 전기방사하여 나노섬유 부직포를 제조하는 방법에 관한 것이다. 본 발명의 제조방법으로 제조한 나노섬유 부직포는 섬유가닥에 무기입자가 혼입되어 공기와 접촉되는 무기입자의 표면적이 커서 무기입자의 효능과 지속성을 극대화 할 수 있다. 이에 따라 고효율로 원적외선을 방출하면서도 항균 및 소취 특성이 우수한 나노섬유 부직포를 얻을 수 있으며, 부직포는 자동차 헤드라이너 등의 내장부품에 유용하게 적용할 수 있다.
