As our whole society has become increasingly aware of safety and emphasizes the importance of preventing safety accidents, the airline cabin service sector is also facing a strong demand to improve practical system for aviation safety education. In this regard, the development of appropriate safety education programs and the getting of human resources who can develop and operate such programs are becoming key issues. This study aims to provide academic and practical implications for safety education and training in airline cabins by reconfirming the importance and direction of safety education in the context of airline cabin services, and by specifying and establishing qualification requirements for personnel who develop and operate such safety programs. To this end, we review the content that should be included in safety training programs, the qualifications required of developers, managers, instructors, and examiners who develop or operate such programs, and how safety training programs can be continually improved as relevant conditions change in the future. In addition, we have also suggested ways to train appropriate managers, instructors, and examiners, including improving the compensation system for them, and how to effectively manage trainees. In order to secure a higher level of aviation safety in the future, it will be necessary to continue research on the development of more diverse and high-quality aviation safety education programs and the training of related personnel.

Demand for air travel, which shrank sharply following the outbreak of the COVID-19, has recently recovered up to 80% before the spreading pandemic. As a result, the number of passengers are rapidly increasing again. However, financial difficulties and lack of skilled workers in the aftermath of a long-term recession and pandemic lead to a decrease in aviation safety awareness which is fundamental for safety culture. Consequently, this hazard can act as a potential risk factor for the global aviation industry preparing for a new leap forward in the post-pandemic era. Therefore, this study analyzed and defined the four key elements of aviation safety awareness; attitude, belief, perception, and value. Based on this analysis, this study combined the four key elements into the P-D-C-A cycle to derive what top management, middle managers, and workers should each do to continuously improve the positive safety culture.

Due to the recent rapid increase in passenger and cargo air transport demand, the capacity of Jeju International Airport has been approaching its limit. Even though in COVID-19 crisis which has started from Nov 2019, Jeju International Airport still suffers from strong demand in terms of air passenger and cargo transportation. However, it is an undeniable fact that the delay has also increased in Jeju International Airport. In this study, we analyze the correlation between weather and delayed departure operation based on both datum collected from the historical airline operation information and aviation weather statistics of Jeju International Airport. Adopting machine learning techniques, we then analyze weather condition Jeju International Airport and construct a delay prediction model. The model presented in this study is expected to play a useful role to predict aircraft departure delay and contribute to enhance aircraft operation efficiency and punctuality in the Jeju International Airport.

As the majority of Korean MRO demand is outsourced overseas, AMO by major foreign authorities is required to promote the Korean MRO industry to keep Korean MRO demand on shore. This study aims to promote consulting for AMO (obtaining repair station certification) by U.S. Federal Aviation Administration (FAA) for Korean maintenance companies. We analyzed AMO process, studied various industry cases, developed a model for AMO consulting, and identified core competencies for consultants. We suggested a five-step modified Milan model to apply AMO consulting process. We identified seven core competencies (ethics, communications, problem-solving, technical, relationship, resource management, organizational understanding) both social and technical for consultants. Additionally, we text analyzed more than 260 FAA AMO consultant resumes on Linkedin and interpreted frequent words (airline, audit, inspector, DER, regulation, ISO, system) to their competencies. This study contributes to promote consulting for the Korean MRO industry to be recognized by FAA and to develop the Korean MRO industry.

Heuksando is an island which belongs to Shinangun, Jeonllanamdo and is located on the southwest sea of the Korean peninsula. Around this island, there are many beautiful islands which embroider the archipelago such as Hongdo, Soheuksando, Haeuido, Gageodo. However in the transportation mode we could not offer convenience to all the visitors coming to this area because access to this place can be made only by ship from Mokpo harbor. So new airport is desirable to solve this problem in this area. Therefore, this study is forecasting air transportation demand between Heuksando and several domestic places in order to give the fundamental materials not only to address the appropriateness to construct a new airport but also to determine it's size and necessary facilities.

In today's competitive environment, supply chain management is a major concern for a company. Two of the key issues in supply chain management are transportation and inventory management. To achieve significant savings, companies should integrate these two issues instead of treating them separately. In this paper we develop a framework for modeling stochastic programming in a supply chain that is subject to demand uncertainty. With reasonable assumptions, two stochastic programming models are presented, respectively, including a single-period and a multi-period situations. Our assumptions allow us to capture the stochastic nature of the problem and translate it into a deterministic model. And then, based on the genetic algorithm and stochastic simulation, a solution method is developed to solve the model. Finally, the computational results are provided to demonstrate the effectiveness of our model and algorithm.

In order to predict the future needs of the aircraft repair parts, each military group develops and applies various techniques to their characteristics. However, the aircraft and the equipped weapon systems are becoming increasingly advanced, and there is a problem in improving the hit rate by applying the existing demand prediction technique due to the change of the aircraft condition according to the long term operation of the aircraft. In this study, we propose a new prediction model based on the conventional time-series analysis technique to improve the prediction accuracy of aircraft repair parts by using machine learning model. And we show the most effective predictive method by demonstrating the change of hit rate based on actual data.

In Korea, there is great lack in jet lease agreements compared to many other countries. Due to such scarcity in numbers of jet lease agreements, problems have never truly surfaced and legal foundation dealing with such issues have not yet been formulated. However, as the globalization is making the world smaller and smaller, the demand for jets will grow. As the Korean aviation industry is expanding tremendously, although very preliminary at this time, the interest and actual execution on private jet lease agreements will grow. The prediction of increase in the private jet ownership is causing the lease industry to be nervous and may require particular preparatory foundation works. Particularly, legal analysis and detailed review maybe necessary to set a precedent with will serve as the grounded rule in the future. It is notable that Vietnam, a country which is believed have a less developed aviation industry than Korea, had already established a specialized jet leasing company, VALC in 2007. Also, when leasing an airplane from a foreign financial institution, it is possible to obtain a government issued guarantee. Therefore, it is urgent for Korea to prepare the legal foundation for the future demands in aviation leasing, as well as private jet leases which in turn would promote national wealth and further develop the financial industry.

The proportion of airline accidents caused by human factors is steadily increasing. The aviation industry has made considerable progress in reducing the accident rate; however, since the early 1980s, the accident rate has remained constant. Due to airspace congestion, the safety margins of these existing safety promotion methods are gradually decreasing; thus, new methods to prevent accidents and quasi-accidents must be devised. Causative factors of aviation accidents include increased air traffic due to increased air demand, increased cumulative working hours due to long-distance flights, and complicated flight environments. Accidents often occur when several small errors accumulate in the normal course of operation, rather than after a single error. Accordingly, in this study, the impacts on air navigation due to human error by aviation maintenance personnel and varying international standards (i.e., KOCA vs. F.A.A vs. EASA) analyzed, and the relationship between human decision-making and behavior was investigated. The resulting safety analysis and alternatives were presented to prevent aviation maintenance accidents and cognitive ergonomics errors.

In response to the recent surge in aviation demand, major airport and aviation authorities continue to make efforts to formulate arrival procedures that take into account efficient aircraft separation, noise and environmental issues related to carbon (CO₂) emissions. In order to ensure efficient traffic control and environmental issues, as a result, a new concept Trombone, Point Merge, etc. have been introduced and widely used. However, these new concept incisions are becoming a factor that hinders operational efficiency and stability due to the restricted domestic airspace such as military airspace and excessive constraints of altitude, speed, etc. which do not reflect the concept of continuous descent operation and eventually needs to be modified to make continuous descent operation as feasible as possible. We herewith analyze and propose the way of improving flight safety and efficiency in the arrival operation procedure by supplementary modification which consequently contribute to the aviation industry international competitiveness.
