The International air transportation industry provides a vital communication link which brings prosperity to many states in our modern age. This invaluable link has been threatened by terrorism. Airlines have been one of the most attractive targets in the eyes of terrorists for several reasons, including particularly the international and symbolic nature of aviation, and the potential of multigovernmental involvement which can inevitably generate wide publicity. Terrorist attacks against civil aviation have been committed since the earliest days of civil aviation history. The first attack against civil aircraft dates back to the early 1930s. Since then, aircraft hijacking and other forms of attack against air transport operations have become one of the most serious challenges to the safety of flying. In recent years, a new form of threats against civil aviation has appeared. Man-portable air defense systems (MANPADS) in the hands of criminals, terrorists, and other non-state actors pose a serious potential threat to passenger air travel, the commercial aviation industry, and military aircraft around the world. The purpose of this study is to provide some countermeasures against such attacks. In order to foster a better understanding of the problem, an introduction of MANPADS and a brief history of attacks using MANPADS are presented. It also examines the level of threats, trends of attacks using MANPADS and the possible countermeasures to be taken by the international community.

In this paper, we classified a flight pattern of unmanned aerial vehicle(UAV) which will be operating in UTM system and analyzed its flight pattern by purpose of use. Flight patterns of UAV are sorted into three patterns which are circling, monitoring and delivery. We considered four cases of industry areas using UAV which are agriculture, infrastructure monitoring, public safety & security(p.s.s) and delivery. It is necessary to build a simulation model as a verification tool for applying the flight pattern according to the use of UAV to the real UTM system. Therefore, we propose the simulation model of UAV with updating states over time. We applied simulation to UAV monitoring flight pattern, and confirmed that the flight was done by the given input data. The simulation model will be used in the future to verify that the UAV has various flight patterns and can operate safely and efficiently for the intended use.

The air transport industry is experiencing unprecedented fluctuations in aviation demand through the Covid-19 pandemic, and is more focused than ever on maintaining and generating business profitability. During the pandemic, demand for air cargo has soared, and the conversion business from passenger aircrafts to freighters(P2F) is drawing attention as a new business in the aviation maintenance industry. This study derives important factors to be considered in order to successfully carry out the P2F project through a wide range of cases and related literature, and analyzes the relative importance of each factor using the analytic hierarchy process. Through a survey of 33 aviation maintenance experts with more than 20 years of field experience, the importance of main factors and their sub factors was determined and implications were drawn. As a primary result, in order to succeed in the P2F project, the main factors were identified in the order of skill, finance, and location. The most important sub factors for each main factors were identified in order of securing airframe modification skill, securing infrastructure construction cost, and creating P2F business complex and district. The quantified success factors suggested the critical direction for the successful development of Korea's P2F business, and presented viable and specific business strategies and implementation plans for each factors.

Until Montreal Convention was established in 1999, the Warsaw System is undoubtedly accepted private international air law treaty and has played major role on the carrier's liability in international aviation transport industry. But the whole Warsaw System, though it was revised many times to meet the rapid developments of the aviation transport industry, is so complicated, tangled and outdated. This thesis, therefore, aim to introduce the Montreal Convention by interpreting it as a new legal instrument on the air carrier's liability, specially on the passenger's, and analyzing all the issues relating to it. The Montreal Convention markedly changed the rules governing international carriage by air. The Montreal Convention has modernized and consolidated the old Warsaw System of international instruments of private international air law into one legal instrument. One of the most significant features of the Montreal Convention is that it sifted its priority to the protection of the interest of the consumers from the protection of the carrier which originally the Warsaw Convention intended to protect the fledgling international air transport business. Two major features of the Montreal Convention adopts are the Two-tier Liability System and the Fifth Jurisdiction. In case of death or bodily injury to passengers, the Montreal Convention introduces a two-tier liability system. The first tier includes strict liability up to 100,000SDR, irrespective of carriers' fault. The second tier is based on presumption of fault of carrier and has no limit of liability. Regarding Jurisdiction, the Montreal Convention expands upon the four jurisdiction in which the carrier could be sued by adding a fifth jurisdiction, i.e., a passenger can bring suit in a country in which he or she has their permanent and principal residence and in which the carrier provides a services for the carriage of passengers by either its own aircraft or through a commercial agreement. Other features are introducing the advance payment, electronic ticketing, compulsory insurance and regulation on the contracting and actual carrier etc. As we see some major features of the Montreal Convention, the Convention heralds the single biggest change in the international aviation liability and there can be no doubt it will prevail the international aviation transport world in the future. Our government signed this Convention on 20th Sep. 2007 and it came into effect on 29th Dec. 2007 domestically. Thus, it was recognized that domestic carriers can adequately and independently manage the change of risks of liability. I, therefore, would like to suggest our country's aviation industry including newly-born low cost carrier prepare some countermeasures domestically that are necessary to the enforcement of the Convention.

With the development of information and communication technology, the unmanned aerial vehicle industry began to attract attention as a new growth industry as it entered the fourth industrial revolution. As the size of the unmanned aerial vehicles and the scope of airspace vary from small drones to large unmanned aerial vehicles, the developed countries such as USA and Europe are developing plans for the integrated operation of manned and unmanned aerial vehicles. ICAO is also working on amendments to the relevant ICAO annexes to establish international standards and recommendations for unmanned aerial vehicles. Korea also needs to prepare for the integrated operation of manned and unmanned aerial vehicles that will come in the future, and for this purpose, it is necessary to review and revise the national regulation systems for the safe operation of unmanned aerial vehicles. This study analyzes the amendments of related annexes discussed on the Remotely Piloted Aircraft System (RPAS) pannel, and suggests the direction of revision of the Aviation Safety Act for the safe operation of unmanned aerial vehicles in comparison with the existing Aviation Safety Act.

Global warming has become one of the most important social responsibilities. After Kyoto protocol for greenhouse gas reduction by climatic change convention came into effect, developed countries are presenting various policies to reduce greenhouse gas that is produced in transport field. One of those policies is modal shift that change from road freight to sea, inland waterway and railway transportation that is eco-friendly. Because increase of road freight brings about road congestion and accident, logistics cost, air pollution and green house gases. Railways are superior to all other modes of transport in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. In developed country's government actively promoted relevant legislation, policies, and countermeasures known as modal shift policies to shift freight transport from road to large volume mode such as railway and ship. In this paper, we discuss the current situation in modal shift, compare it with cases in other countries EU and Japan, identify problems in Korea, and propose the following ways to enhance competitiveness of rail freight.

In this paper, the types of airport operation are categorized four groups in context of ownership and operational management; full government ownership and operation; government ownership with privatization of selected service; government ownership and private management; private ownership and operation. The term,"Privatization" has a different definition when it is used in different contexts and cultures. In this paper, the definition of"Privatization" in the context of airport, is that the movement of an entity from the government sector to the private sector. To keep pace with the remarkable growth in the air traffic volume of passengers and cargo, more and more mega-international airports have been built or are under construction. As the air transport demand is expected to increase at an even greater rate in the 21st century, the need for new conception airport is merging to solve the current problems such as airport congestions and flight delays which will be essential factors to decide whether the competitive airports or not. Presently, we researched the type of the operational management to strengthen the competitiveness for Korea's airports. Specifically, It is focused on the government ownership with privatization of selected services. It seems to be evaluated as government ownership and private management when it is actively utilized within Korea Airport Authority's law or Inchon International Airport's public corporation law. To make more competitive airport in 21st Century, however, it is desirable to seek for the method to gradually evaluate to private ownership and operation.
