The air transportation industry in Korea has grown very fast in aspect of the transportation scale as much as entering within the tenth in the world. However, as compared with the air transportation industry, the civil aviation pilots training has been performed at very low level in quantity and quality because of the high cost of pilots training, nation security, limited airspace use and falling behind of the science technology in relation to the aviation industry. In result, the number of airline pilots became lower than actual demands of both airlines, KAL and ASIANA. This produced many foreign captains employed, airline pilots overloaded and finally affected flight safety. In this paper, it was studied the actual reality and problems of civil aviation pilots training and presented the encouraging policies for civil aviation pilots training in Korea.

지형적 경계 (geofence)란 무인기가 침범하거나 또는 벗어나지 말아야 할 영역을 설정해 놓은 가상의 경계로서, 저고도 무인기 교통관리체계(UAS traffic management)의 필수적인 구성요소 중 하나이다. 본 연구에서는 perpendicular 알고리즘을 개선하여 지형적 경계를 단순화하는 기법을 제안한다. 제안된 기법을 실제 건물을 측정하여 얻은 데이터에 적용하여 성능을 평가하였으며, 제안된 방법이 기존 방법에 비해 공간적 낭비를 최소화하면서도 꼭짓점의 개수를 효과적으로 줄임을 확인하였다.
