Manned-unmanned teaming can be a very promising air-to-air combat tactic since it can maximize the advantage of combining human insight with the robustness of the machine. The rapid advances in artificial intelligence and autonomous control technology will speed up the development of manned-unmanned teaming air-to-air combat system. In this paper, we introduce a manned-unmanned teaming air-to-air combat tactic which is composed of a manned aircraft and an UAV. In this tactic, a manned aircraft equipped with radar is functioning both as a sensor to detect the hostile aircraft and as a controller to direct the UAV to engage the hostile aircraft. The UAV equipped with missiles is functioning as an actor to engage the hostile aircraft. We also developed a combat scenario of executing this tactic where the manned-unmanned teaming is engaging a hostile aircraft. The hostile aircraft is equipped with both missiles and radar. To demonstrate the efficiency of the tactic, we run the simulation of the scenario of the tactic. Using the simulation, we found the optimal formation and maneuver for the manned-unmanned teaming where the manned-unmanned teaming can survive while the hostile aircraft is shot-downed. The result of this study can provide an insight to how manned aircraft can collaborate with UAV to carry out air-to-air combat missions.

Recently, Korea Air Force has been facing a lot of problems in its pilot training system such as training time shortage due to the expensive gas price, noise pollution and difficulties in finding airspace for training. To tackle these problems, a new training system (called L-V training system) using both aircraft and its simulator has been suggested. In the system, a data link is established between aircraft and simulator to exchange their flight information. Using the flight information of simulator, aircraft can perform various air missions with or against imaginary aircraft (i.e., simulator). For this system, it is crucially important that fair fighting condition has to be guaranteed between aircraft and simulator. In this paper, we suggested an approach to impose a maneuvering restriction to simulator in order to provide fair fighting condition between aircraft and simulator.

방사선 치료에서 일정한 호흡주기의 유지가 필요한 흉부 및 복부를 치료할 때 환자의 자세와 belly board device의 사용 여부에 따라 다르게 나타나는 호흡신호의 차이를 통계적으로 분석하여 임상적용에 관한 유용성을 검정하였다. 호 흡주기유지는 supine 자세에서 비교적 양호하게 나타났으며, prone 자세에서 호흡주기 유지가 양호하지 않은 경우에 belly board를 적용하여 85%가 유의하게 다른 패턴의 호흡주기를 보였고, 57%는 호흡주기 유지가 양호하게 변화한 것으로 나타났다. 각 피험자의 비만도와 체중에 따른 호흡주기유지 안정성의 차이는 보이지 않았으며, 안정성의 상대 적 비교지수로 분석한 시간의 흐름에 따른 호흡의 안정성 유지는 supine 자세에서 비교적 안정적이었으며, 호흡주기 유지의 검정통계결과와 일치하였다(p=0.044, kappa=0.607). 흉부 및 복부 심지어 골반의 방사선치료에서도 호흡에 의한 환자의 움직임은 중요한 고려사항 중 하나이다. 환자의 치료부위와 target의 위치, 예상되는 plan의 beam arrangement에 따라, 환자의 자세 및 device의 여부가 결정되지만, 본 연구와 같이 호흡신호의 통계적 분석과 이의 적 용을 통해, 호흡유지에 최적의 자세, belly board와 같은 device 사용여부를 결정하여, 호흡주기의 유지 및 호흡의 안정 도 유지에 기여할 수 있을 것으로 사료된다.
