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.

It is difficult to expect the service improvements such as increased number of sailing and making new ship due to financial difficulty this is caused by deterioration of island dwellers. In addition, the safety of ship operation is also a problem with the supply of good sailors difficult problem of low wages and lack of safety working environment. T It is necessary to ensure the introduction of public operating system in coastal passenger shipping business to secure the public and safety. There are many practical constraints but if we obtain public sea ways, it will be possible to improve the operating system through the implementation from a subsidized line and taking off business licenses of an insolvent enterprise by enhancing safety control.

An analysis method of trajectory prediction has been suggested and the developed trajectory prediction module, which is an important functional component of the Arrival Manager (AMAN) of Jeju airport, has been tested by applying the suggested method. The objective of this method is to improve prediction performance of the trajectory prediction module. The trajectory prediction module predicts the trajectories based on the real-time track data and flight plans. Therefore, the suggested analysis method includes the simulation framework which is based on real-time playback, recording, and graphic display systems for testing. Besides, the definition of time error, which is a important index for the time based scheduling system, such as AMAN, is included in the suggested analysis method. An example of arrival time prediction accuracy improvement through the suggested analysis method has also been presented.

As the marine transportation has increased, the safe maneuvering system has been required. SOLAS obligated regulations for carrying AIS(Automatic Identification System) onboard. This system provides navigational information including identification, classification, position, a ship's course and voyage status from own vessel to ground and other vessels. Being utilized in the most development of application service for safe maneuvering, they are to be managed systematic. In this paper, we introduce a database system to manage the voyage status and navigational information of AIS message. It is classified by static or dynamic. An electronic navigational chart display system is implemented to verify the design.

The traditional regulatory approach to managing pilots fatigue has been to prescribe limits on maximum daily, monthly, and yearly flight and duty hours, and require minimum breaks within and between duty periods. This approach comes from a long history of limits on working hours dating back to the industrial revolution. So, the Council of ICAO recently adopted International Commercial Air Transport regarding the development and implementation of fatigue risk management systems(FRMS). The FRMS can provide better safety outcomes than current prescriptive flight and duty regulations while allowing greater operational flexibility. This study aim to analyzing relative importance of pilots' fatigue factors in order to minimize pilots' fatigue-related safety risks. More researches regarding monitoring and managing fatigue, based upon scientific principles, are required in the future.

UTM is an air traffic management ecosystem under development for autonomously controlled operations of UAS by the FAA, NASA, other federal partner agencies, and industry. They are collaboratively exploring concepts of operation, data exchange requirements, and a supporting framework to enable multiple UAS operations beyond visual line-of-sight at altitudes under AGL 500ft in airspace where air traffic services are not provided. Minimum Safe Altitude is a generic expression, used in various cases to denote an altitude below which it is unsafe to fly owing to presence of terrain or obstacles. The European drone regulation mentions that the UAS is maintained within 120 metres from the closest point of the surface of the earth during flight, except when overflying an obstacle. This study attempted to develop a minimum flight altitude database system. Based on domestic and international rules and regulations on setting the minimum flight altitude it is expected that it can be applied to the operation of aircraft and unmanned aerial system in UTM environments for specific area in Korea.

The overall Air Force's serious accident rate is decreasing, but the trainer's accident rate is on the rise from 0.24% in '00~'09 to 0.77% in '01~'19. Base on the SHELL model recommended by the ICAO, the risk factors of the introductory flight training course were analyzed, implications were examined, and safety promotion measures were proposed. A survey of 25 questions was organized based on regulations, guidelines, and related data for each component of the SHELL model in accordance with the introductory course of Air Force flight training. The survey was divided into a student group and instructor group and compared and analyzed into L-L, L-S, L-H, and L-E based on the results after conducting it, and implications for this were derived. Compared to other analysis factors, L-L showed that the average of the instructor group was relatively higher that of the student group in all questions.

K-drone delivery system is a commercial delivery system that ensures compliance with aviation safety. It is equipped with flight routes for automated deliveries and features a drone identification device along with a real-time monitoring system for drone positions. This study proposes the application of an ICAO SMS-based safety management system as an appropriate safety management framework that non-aviation personnel drone operators can adopt. It suggests that applying an ICAO SMS-based safety management system to the K-drone delivery system, similar to Europe and the USA, is valid. To introduce ICAO SMS into the K-drone delivery system, procedures must be established for building a drone safety management system, from business registration to drone operation and training. The main components of the drone safety management system are presented, including 8 items: safety policy and authority and responsibility, risk management, safety assurance, safety promotion, drone control system, drone delivery operation manual, drone maintenance manual, and accident response, incorporating the four fundamental elements of ICAO SMS and European Light UAV operator Certificate standards. Additionally, as a core aspect of the drone safety management system, a seven-step risk assessment procedure is proposed, which includes basic risk identification, hazard identification, risk scenario development, calculation of severity and likelihood, SMS matrix risk assessment, mitigation measures, and implementation determination.

Aircraft fuel cost is the largest airline expenses in airlines who play a major role in air transportation system. Airlines have been making a great effort to save fuel as much as they can. Among these efforts, the systematic fueling strategy has been taken a growing attention since it is recognized as a very cost-effective fuel management strategy. The systematic fueling strategy is the fuel saving strategy in which extra amount of fuel is loaded to utilize the fueling cost differentiation among the cities where the aircraft operate. In this paper, the aircraft fueling optimization model is proposed. The proposed model is to calculate precise amount of loaded fuel to minimize overall fuel cost assuming that the aircraft routing for all aircrafts and fueling cost in all airports where the aircraft fly are given. Compared with heuristic fueling strategy, the result of the proposed model is promising. Therefore, it is expected that the proposed model plays a major role in fuel management strategy in airline operation.
