Domestic nuclear facilities establish a physical protection system to respond to illegal transfer of nuclear materials and sabotage to nuclear materials and nuclear facilities, and operate a security search system in order to prevent the entry of controlled items into the facility. X-ray security search is also the most widely used for such security search. Since 2018, Korea Institute of Nuclear Nonproliferation and Control (KINAC) has developed the “X-ray security screening Web-Based Training Program (XWBT)” and has been using it in the physical protection education. The XWBT contains about 700 X-ray images of the item, and can learn X-ray images by type or package of the item. In addition, trainees can practice reading the X-ray image of the item or package, looking for controlled items, and determining whether the item could be passed or opened. However, there is a limit to Web-Based X-ray training program alone. This is because even if the same item is contained in the same bag, the X-ray image could be varied depending on the direction, angle, and other items in the package. Therefore, in addition to XWBT, X-ray reading practice education for actual luggage should be conducted in parallel. In addition, trainees should be familiar with various images through repetitive X-ray reading practice training so that they should be able to intuitively read X-ray images and find controlled items. Therefore, securing educational time is essential to produce skilled trainees. Korea Aviation Security Academy (KASA), which produces professional security inspectors, has established and operated a “Security search education filed for actual luggage” where trainees can pack their own bags, read X-ray images, and practice whether there are controlled items packed. In addition, KASA provides 40-hour training for security search personnel, which focuses on improving the practical skills that security search personnel must have. This study describes the current status of “X-ray Security Search” of Physical Protection Education for security personnel and presents course improvements through the case of KASA.

해상보안사고 리스크 저감을 위해서는 보안위협의 사전색출과 선제적 대비/대응이 중요하다. 다양해지는 해상보안사고의 예방/대비/대응/복구 단계를 입체적이고 통합적인 대응을 위해서 고강도 위협 대응에 집중된 군중심의 경계활동에서 해양경찰청으로 이관을 계획하고 있는 등 해상보안리스크 기반으로 대응전략이 바뀌고 있다. 해군과 해양경찰청이 운영하고 있는 해상 선박검색반은 보안위협의 사전인지를 위한 효과적인 방법으로 평가받고 있으며 선박의 활동으로 발생할 수 있는 해상보안사고를 차단하기위해 정선․검색․나포 등을 수행하고 있다. 본 연구에서는 선박검색반의 효과적인 직무 메카니즘 개발을 위한 기초연구로 선박검색반의 현황과 선박검색에 나타난 해상보안위협의 특성을 분석하였다.
