  • 본 논문에서는 광대역 무선 네트워크 환경에서 제공되는 스트리밍 서비스의 품질 보장을 위한 적응적 전송률 제어 기법을 제안한다. 기존 기법들은 다수의 사용자들이 존재하는 광대역 무선 네트워크 환경에서 적응적으로 전송률을 조절하지 못하여 네트워크 자원 활용도가 낮고 패킷 손실률이 큰 문제점이 있다. 이를 해결하기 위해 제안하는 기법은 기지국에 접속한 단말의 수와 네트워크 상태를 고려하여 전송률을 조절한다. 실험 결과를 통해 낮은 패킷 손실률과 전송률 향상을 확인하였다.

  • To identify eriodictyol from the leaves of Lespedeza maximowiczii C.K. $S_{CHNEIDER}$, growing in Korea, the fresh leaves collected at Mt. Chil Bo, Geong Gi Province were used in the investigation. A white crystal was isolated from the water extract and it was identified as eriodictyol by its melting point, physico-chemical properties, thin layer chromatography and infrared absorption spectrum patterns.

  • 394 strains of soil microorganism were isolated from the Korean soil samples. The isolated strains were shake-cultured in oat-meal medium. The filtrates of the cultures were screened for the production of ${\alpha}-amylase$ inhibitors. Five strains were identified to produce ${\alpha}-amylase$ inhibitors. And these strains were identified as Actinomycetes.

  • 현재 항공기 운항 승무원의 효율적 관리를 위하여 CRM과 LOFT 교육 프로그램이 개발되었다. 이는 Blake & Mouton에 의한 리더십의 유형을 과업과 사람에 대한 관심 정도로 구분하여 5가지 유형으로 나누어 분석하고, 이를 훈련에 적용하고 있다. 그러나 사람의 성격 유형은 보다 복잡하고, 이에 대한 깊은 연구가 요구됨에 따라 본 연구에서 Enneagram에 의한 성격 유형을 고찰하고 민항공사 조종사들의 성격 유형과 성격별 선호 성격 그리고 과업 성과를 높이기 위한 성격간 상호 작용을 규명하여 항공기 운항 승무원 관리에 적용 할 수 있도록 하였다.
