The importance of aviation safety has been emphasized recently due to the development of aviation industry. Despite the efforts of each country and the improvement of screening equipment, screening tasks are still difficult and detection failures are frequent. The purpose of this study was to examine the effect of feedback on improving signal detection performance applying a Simulated Baggage Screening Program(SBSP) for improving aviation safety. SBSP consists of three parts: image combination, option setting and experiment. The experimental images were color-coded to reflect the items' transmittance of the x-rays and could be combined as researchers' need. In the option, the researcher could set up the information, incentive, and comments needed for training to be delivered on a number of tasks and times. Experiment was conducted using SBSP and participant's performance information (hit, missed, false alarms, correct rejection, reaction time, etc.) was automatically calculated and stored. A total of 50 participants participated and each participant was randomly assigned to feedback and non-feedback group. Participants performed a total of 200 tasks and 20(10%) contained target object(gun and knife). The results showed that when the feedback was provided, the hit, correct rejection ratio and d′ were increased, however, the false alarms and miss decreased. However, there was no significant difference in response criteria(${\beta}$). In addition, implications, limitations of this study and future research were discussed.

본 연구의 목적은 수화물 검사 과제에서 장 복잡성과 위험물품 종류가 탐지율과 반응시간에 미치는 효과를 검증하는 것이었다. 참가자는 C 대학 학부생 62명이었고(남 45.2%, 여 54.8%), 평균 나이는 22.88세였다. 가상 수화물 심사(신호 탐지) 과제를 개발하여 사용하였고 참가자들은 실험에 대한 오리엔테이션과 과제 연습에 참가한 후 본 실험에 참가하였다. 참가자들은 총 200개의 수화물 검사 과제를 실시하였고 40개(20%)가 위험 물품을 포함하고 있었다. 본 연구의 독립변인 중 장 복잡성은 상(20개), 중(14개), 하(8개) 세 수준으로 위험 물품의 종류는 총, 칼, 액체, 그리고 라이터 4가지로 설정하였다. 종속변인은 위험 물품이 있는 이미지 중 표적 신호를 탐지한 비율(%)이었다. 연구 결과 장이 복잡할수록 탐지율이 유의미하게 감소하였고, 반응시간은 증가하였다. 그리고 위험 물품의 종류에 따라 탐지율과 반응시간은 달라지는 것으로 나타났다. 특히 칼의 탐지율이 가장 높았고 반응시간은 가장 짧았으며 액체의 탐지율이 가장 낮고, 반응시간은 길었다. 장 복잡성과 위험 물품의 상호작용 효과 역시 탐지율과 반응시간에 영향을 미쳤다. 칼은 장 복잡성에 영향을 받지 않았고, 라이터와 같이 작은 물품이 장 복잡성의 영향을 가장 크게 받은 것으로 나타났다.

Airport is shifted airport 1.0 to airport 4.0 called smart airport and services paradigm is changed into direction to point the customer targeted benefits. Smart airports make use of integrated Internet of Things components to provide added-value services. By integrating smart components, airports are being exposed to a larger attack surface and new attack vectors. Self-services such as web or mobile check-in, self check-in/tagging/back drop/boarding, etc. should be strengthened to make airport processes smarter, and technologies such as automatic immigration, smart security search, and automatic AI-based baggage search should be applied. In this paper, we describe the necessity and importance of smart airports and next generation security screening technology. Further, we describe a walk through-type smart security screening system.

As intellectual terror threats increase, we feel the limit in coping with those threats and the things we do are placing traditional X-ray machines & ETD and increasing aviation security staffs. In fact, even if air transportation system is the fast and most efficient transportation methods, it is true that there are many inconveniences to endure due to terror threats. In the name of security, even if we make a lot of efforts and time to screen both good-natured passengers, baggage, cargo and suspicious passengers, it is impossible to screen perfectly and it is not an efficient methods. Therefore, we introduce profiling system that reduce the effort to screen good-natured passengers but focus on screening dangerous passengers and baggages. Profiling system strengthens aviation security, using the concept "Selection & Concentration". Israel started to introduce manual profiling system in aviation security, which is interviewing suspicious passengers and it has been used in crime investigation since 1960. And it has been upgraded and diversified to CAPPS(Computer Assisted Passenger Screening Program) and SPOT(Screening Passenger by Observation). So, this theses is to study on the concept & kind of profiling and profiling methods adopted in airlines. Also it presents the method of introduction of profiling system in Korea and the necessity of making law on it.

Cost reduction and equality by exempting re-scanning of passengers, baggage and cargo secured from the first airport of departure, mainly in the European Union/European Economic Area(EU/EEA), Switzerland, etc. One-Stop Security(OSS) is being promoted to maintain the level of security while increasing speed and convenience, and movement is expected to expand worldwide. Therefore, this paper establishes the basic concept of OSS through a literature review of ICAO Standards and Recommended Practices(SARPs), and analyzes the actual conditions of OSS implementation in major countries such as the United States and the EU. It is intended to present the political, economic benefits for Korea and highlight the urgency of implementing the OSS system in the aviation industry including the cargo sector. Therefore, the practical implications of strengthening international cooperation through the expansion of government and airport operators OSS implementation to overcome the resource shortage problem of the existing national air cargo security system and to strengthen the status as a global aviation powerhouse were drawn up. There is academic significance that it raised the need for effective implementation of OSS, which was not previously covered.
