  • The study examined the effects of shift pattern and expertise on perceived workload and performance for aviation security screeners. 18 security screeners participated in this study, in which data were analyzed by dividing them into two groups (experts vs. less-experts). We measured their perceived workloads and performances (i.e., reading time through X-ray) as a function of shift pattern and time condition. As a result, highly experienced screeners (experts) showed high workload during the morning shift, while lowly experienced screeners (less-experts) reported high workload during the full-day and the afternoon shifts. In addition, less-experts took a longer time to inspect the baggage when they worked for the full-day and the afternoon shifts. Particularly, in the last time slot of the full-dat shift, expert screeners had a high workload, while both groups showed a high-level of workload at around 17:30 in the afternoon shift.

  • Countries recognize seriousness and concern about aviation terrorism, try to stamp out of it but aviation terrorism has been increasing in the world. Airport security is completely up to the result of security screening for passengers, check-in baggages and cargo at the check point. To complete effectively human and physical screening at the airport, it is essential to secure modernized screening equipment and specialized security screener, and airport security supervisor to supervising them. In this study, A survey conducted to find out the effect on screening equipment operating factors of airport security supervisor's individual attitude. The results of the study are as follow First, the duty view of airport security supervisor meaningfully affect expertise of screening equipment operating factors, satisfaction, reliability, and education and training, national point of view meaningfullly doesn't affect screening equipment operating factors. Second, the working condition effects on the education and training, if the working condition is getting better, intent to change occupation is getting lower. Third, duty stress meaningfully effects on the intent to change occupation, now airport security supervisor works in poor condition. Therefore, airport security supervisor needs to be prude of protecting the airport from the terrorism and various attacks and various kinds of aviation security regulations and procedures and comply with operating standards and keep the life of the country and its people, and needs to change awareness. And It is nessasary for government or airport authority or airline to prepare countermeasure for the improvement of their labor conditions.

  • According to the Annex 17 to the Convention on International Civil Aviation, an appropriate authority of each contracting state has to define and allocate tasks and coordinate activities between the departments, agencies and other organizations of the State, airport and aircraft operators and other entities concerned with or responsible for the implementation of various aspects of the national civil aviation security programme. The airport has to take leading role in implementing security tasks at airport area because the airport operator is the provider of airport facilities and services to its customer and the security activities belong to its services. So Republic of Korea Government enact the Law, Aviation Safety and Security. The Purpose of this Act is to prevent any unlawful act in airport facilities with international conventions, including the ICAO to provide for standards, procedures and mandatory matters needed to ensure the safety and security of civil aviation. But the Act has some error. So is this paper to review the revision of aviation security regulation and the changes of aviation security responsibilities and task assignment. There is the term "aviation security personnel", who are charged with the task of preventing any act of disrupting the order and safety in airport. But there is no term "security screening personnel" who performs to detect or search for dangerous object, such as weapons or explosives, which may be used for the unlawful obstruction.

  • In recent years, X-ray cargo inspection systems have been rapidly being installed at ports, airports, and borders to strengthen the security of baggage and the prohibition of transaction with drugs and contraband. We at Korea Atomic Energy Research Institute are currently developing a dual-energy X-ray cargo inspection system. In this study, a 64-channel charge sensitive readout system consisting of two 32-channel readout systems has been designed for collecting and amplifying signal charges from detector arrays. The 32-channel readout system was composed of 8 detector arrays (four photodiodes per one detector array, 2 mm pitch), 32 hold switches, 32 charge integrators, 32 reset switches, 32 sample-and-holds, 32 output switches, an output buffer, a frequency divider (divide by 4), and a 32-bit shift register. Each component was well designed and optimized for our system, and the size of the fabricated circuit board is $135mm{\times}71.5mm$. From the visible light tests, the output pulses and the corresponding images were successfully acquired according to the intensity of the incident light.

  • In general, an airport access system has influenced on airport terminal operation. The congestion and delay in service facilities at an airport are definitely depended on the patterns of passenger arrival behavior and time spent in a terminal. Therefore, it is necessary to analyze the passenger arrival behavior at an airport to improve the operations at passenger terminal. Passenger arrival patterns to an airport are mainly depended on factors such as the length of access time. reliability of access time. and provision of transport modes, etc. The focus of this paper is to estimate the relationship between the length of access time and passenger's total time spent to board aeroplane. For this, passenger surveys were conducted at the Gimpo International Airport for a large airport and Sacheon Airport for a small size airport. The mathematical relationship between arrival time at an airport prior to the scheduled time of departure(STD) and access time spent was then estimated. It is considered that the results of this study can be used to reduce congestion and delays, thereby to improve the efficiency of the passenger services at the airports.
