본 논문에서는 우선 순위 기반의 예약 코드 다중 접속 (P-RCMA) 프로토콜을 제안한다. P-PCMA는 기존의 RCMA 프로토콜의 음성 트래픽 성능을 개선한다. P-RCMA는 두 개의 전력 수준을 유지하고 패킷 전송을 위해 공유된 코드를 경쟁하는 시점에 트래픽의 전송 특성을 고려한다. P-RCMA는 기지국 수신 단에서 전력 세기에 따른 캡쳐 효과를 이용하여 데이터 패킷보다는 음성 예약 패킷에 우선순위를 부여한다. 성능 분석은 EPA(equilibrium point analysis) 방법과 시뮬레이션을 이용하고 성능 척도로 음성 패킷 손실 확률 (voice packet...

본 연구에서는 개정범용토양유실공식(RUSLE: Revised Universal Soil Loss Equation)을 이용하여 미국 South Carolina 주 Congaree 유역에 대한 평균 연간 토양 유실량을 산출 하였으며 비점오염원 토양 유실 민감지역을 추출하였다. 평균 연간 토양 유실량은 강우-유출 침식성 인자, 토양침식성 인자, 지면특성 인자, 식생피복 인자, 그리고 토양보존 인자의 곱으로 계산할 수 있으며, 토양 유실 민감지역은 토양 유실량이 토양침식 허용량을 초과하는 지역으로 추출할 수 있다. 연구 결과, 전체 면적의 10% 이상의 면적이 비점오염원...

Objective: This study aimed to investigate the effect of different-sized airways of the inspiratory muscle trainer (IMT) on maximal inspiratory pressure (MIP) and the rating of perceived exertion, as measured by the modified Borg scale (m-Borg). Design: Cross-sectional study. Methods: Twenty healthy subjects (10 men, 10 women) volunteered for the study. The spirometry was used to measure MIP. The trial order of the three spirometry conditions was chosen randomly. After measuring the MIP and...
