Food irradiation is beginning to provide a safe, effective, and economical alternative treatment for many food products, especially for the raw food of animal origin. The historical background and wholesomeness of food irradiation were examined. The application and effect of the process were investigated. The cost and benefit of the irradiated poultry meat were evaluated. The effect of irradiation on the poultry meat, poultry products, and microorganisms were reviewed. With the safety of irradiated poultry meat and poultry products established, the future of the process is promissing.

스마트무인기의 비행시험에 앞서 비행제어시스템을 포함한 전체 무인기 체계의 건전성을 검증하기위한 지상통합시험을 수행하였다. 지상통합시험은 비행체 인터페이스 시험, 비행체 HILS시험, 지상파워시험, 4자유도 치구시험, 안전줄 호버시험 순서로 진행되었으며, 각각의 시험을 통해 전체 무인기 시스템의 안전성을 입증하였다. 본 논문에서는 국내 최초로 개발된 틸트로터인 스마트무인기의 지상시험 절차와 각 시험에서 획득한 데이터 분석결과를 제시하였다. 지상시험 결과 비행제어시스템의 안전성이 충분히 입증되었으며, 비행시험이 수행가능하다고 판단되었다. The tilt-rotor Smart UAV(Unmanned Air Vehicle) has been developed by KARI(Korea Aerospace Research Institute) for civil purposes. In order to prove the reliabilities of total system of Smart UAV, the series of ground tests were performed including system interface test, aircraft HILS(Hardware In the Loop Simulation) Test, ground power test, 4-DOF (Degrees of Freedom) rig test, and tethered hover test. Many unexpected problems occurred at each ground test. With clearing these problems, the total Smart UAV systems were matured and the airworthiness was proven enough. After complete of additional ground test proposed by FRRB(Flight Readiness Review Board), the first flight test will be performed in this year. This paper presents the procedures and the analysis results of the ground tests for the tilt-rotor Smart UAV.
