  • As the number of passengers and the amount of cargo is getting increased, the traffic of aircraft and moving vehicle at an airport is getting busy. Especially, due to the heavy traffic of moving vehicles in the area of airside, the safety management of them is getting important. The study has been performed for suggesting improved methods in order to reduce safety accidents between aircraft and moving vehicles by introducing a safety management system for moving vehicles in airside of an airport. In order to improve the level of safety with the efficient management of moving vehicles in airside, the analysis of the domestic and international trends of the related technology and regulations has been performed. As a result, the conceptual design of safety management system has been suggested by utilizing the location information technology and four layers (hardware, network, middleware and application) approaches of safety management system.

  • Airside 지역 콘크리트 포장의 조인트에 사용되는 충진재는 항공기 이 착륙시 엔진에서 뿜어져 나오는 고열의 후폭풍과 계류장에서 항공기의 정비 및 주유시 항공유 유출에 대한 저항성을 가지고 있어야 한다. 이러한 특성 때문에 공항용 조인트 충진재는 도로포장용과는 다른 충진재의 사용이 요구되고 있다. 본 연구에서는 국내외에서 사용되고 있는 3 종류의 충진재에 대하여 물리적 특성 시험과 성능시험을 실시하였다. 시험재료는 폴리썰파이드, 폴리우레탄, 실리콘을 사용하였다. 시험결과 폴리썰파이드 충진재는 내열성과 내유성에 대한 저항성이 가장 우수하였으며, 폴리우레탄, 실리콘 충진재의 순으로 시험결과가 나타났다. Airside 지역별 특성을 고려했을 때, 폴리썰파이트 충진재는 활주로와 계류장에, 폴리우레탄 충진재는 유도로에 사용하는 것이 적절하며 실리콘 충진재는 Airside 지역 충진재로는 부적합한 것으로 나타났다.

  • OBJECTIVES : This is a basic research for the domestic production of airport-airside deicers. This research selected basic materials for deicers appropriate for the pavement of domestic airports by evaluating the deicing performances of basic materials used in international-standard airport deicers and their impacts on pavements. METHODS : Laboratory investigation was conducted to evaluate the asphalt surface tensile strength, concrete scaling impact, ASR impact, and deicing performances of sodium formate (NaFm), potassium formate (KFm), sodium acetate (NaAc), and potassium acetate (KAc), which are the basic de-icing materials commonly used at international airports, approved by the FAA. In addition, the analyses were also performed on the airside deicer urea, which is currently used in domestic airports. RESULTS : Laboratory investigation confirmed that sodium formate, potassium formate, sodium acetate, and potassium acetate had superior surface tensile strength, concrete scaling impact, and deicing performance compared to airside urea, but they also had greater impacts on concrete ASR. Among these materials, sodium formate had the best asphalt surface tensile strength, concrete scaling impact, and deicing performance, while also having the greatest impact on ASR; hence, mitigation plans for ASR were needed, if it were to be used as airport-airside deicer. CONCLUSIONS : It is necessary to consider additional additives to prevent ASR of concrete pavements when developing airport-airside deicers using sodium formate, potassium formate, sodium acetate, and potassium acetate.

  • The development of Airside Vehicle Control System(AVCS) at Gimpo Airport aims to reduce ground safety accidents in movement area and improve airport operation efficiency and safety management service quality. The vehicle is controlled by a brake controller RTK-antenna and On-Board Diagonostics(OBD) module. Location data is transmitted to a nearby communication base station through a Wi-Fi router and the base station is connected to the AVCS by an optical cable to transmit location data from each vehicle. The vehicle position is precisely corrected to display information using the system. The system allows airport operators to view registered information on aircraft and vehicles and monitor their locations speeds and directions in real time. When a vehicle approaches a dangerous area alarm warnings and remote brake control are possible to prevent accidents caused by carelessness of the driver in advance.

  • In this article, we verify to influence in the management performance by the safety management system that is recommended by the ICAO for the safety management on the airside area in the airport. Also, We present a comprehensive mediator effect that the employees perceive safety culture and safety behavior. We design how participants were selected as study the employees from 4 airports on the airside areas of the Incheon International Airport, Gimpo International Airport, Jeju International Airport and Gimhae International Airport in the Korea using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed. Data analysis was to conduct structural equation modeling. Test of the hypotheses were verified to Maximum Likelihood Estimator. As a result of the analysis, safety behavior and risk management of the safety management system found out that affect management performance. Also, the employees of a high awareness about safety policy could be seen that is a high impact on management performance through a safety culture and a safety behavior. Safety behavior has significant mediator effect within the relationship between the safety management system and management performance. So, We provide guidance of the safety policies for the safety management on the airside area in the airport.

  • For the world's safest air traffic, safety-related areas through the large investment made in a sufficient safe level, but the airport's lack of safety management is concerned about the safety. Airside area is essential area for the flights, and activities of safe management in airside area is very important. Grafting of airside safety management and IT, importance of the safety and efficiency is growing. Advanced airports of world has applied GIS over 10 years ago, and through applying GIS, Airports GIS has been a specialized area. Therefore, this research is for geographic information standards and related laws, providing a guideline of regulations and standards for AIXM (Aeronautical Information Exchange Model), RTCA DO-272A (USER REQUIREMENTS FOR AERODROME MAPPING INFORMATION), FAA Advisory Circular 150/5300 -18A (General Guidance and Specifications for Submission of Aeronautical Survey to NGS: Field Data Collection and Geographic Information System Standards), and by analyzing aviation information and air map(notice "Civil Aviation Safety Authority No. 2009-1"), provide the direction of standardization for air map.

  • 안전관리시스템(Safety Management system, SMS)은 국제민간항공기구(ICAO)에서 정의된 서비스제공자의 의무사항으로 우리나라의 공항 분야는 2005년 부터 구축되어 현재까지 운영되고 있다. 항공교통량 증가에 따른 사고의 발생가능성 증가에 대응하기 위해 채택된 새로운 체계가 SMS라는 점을 고려할 때, 공항 SMS는 항공사와 조업사 등 관련 업체와 연계되며 이동지역에서 근무하는 종사자의 행동에도 긍정적인 영향을 미칠 수 있어야 할 것이다. 본 연구는 인천공항이 실행하고 있는 외부지향적인 SMS활동이 항공사, 조업사 등에 소속된 이동지역 종사자의 지식과 행동에 미치는 영향에 대해 연구하고자 하였다. 총 593명의 종사자가 조사에 참여하였으며, 공항SMS는 안전지식을 통해 안전행동에 영향을 미치는 것으로 나타났다. 이 연구 결과는 공항이 조업사 등 별개의 업체 종사자에 대한 안전정책 설정을 위한 기초자료로 활용될 수 있을 것으로 기대된다.

  • We conducted a study by computational simulation about the effects of frost thickness on the pressure drop and heat transfer characteristics as whole heat exchanger configuration changes. In order to perform the analysis for validation, we assumed that frost properties have constant values and the frost layers that are formed on the fin and tube surfaces are uniform. In order to find the constant thermal conductivity of frost layer, a variety of frost thermal conductivities are performed in our work and compared with the results by Lee et al. [4] and Yang et al. [5] proposed many experimental data about the 2-rows and 2-columns finned tube heat exchanger. The numerical results agreed well with the experimental data when frost conductivity is 0.07W/mK. After the validation had performed, we applied this procedure to the finned tube heat exchanger of domestic refrigeration and investigated the thermo-hydraulic characteristic of the heat exchanger affected by frost thickness according to the inlet velocities and temperatures of air considering the configuration change such as fin pitch.
