  • To manage State Safety Program (SSP) in a more integrative and proactive manner, an aviation safety authority of the state shall detect and assess the risk of emerging or hidden safety hazards before they provoke accidents or incidents(ICAO, 2018). In case of South Korea, safety risk assessment is conducted by calculating the likelihood and severity of the hazard following ICAO's safety management manual. It is reasonable to extract the safety risk likelihood by calculating the number of occurrence caused by the hazard. However, it is ambiguous to assess the safety risk severity defined as the extent of harm that might be expected to occur as a consequence of the identified hazard. In this paper, a safety risk assessment method which quantitatively calculates the risk of hazard using aviation safety data(i.e. aviation safety mandatory report, etc.) is proposed. By utilizing the proposed method, the existing process that safety risk is being subjectively assessed by safety inspectors can be supplemented. So that essential aviation safety policy decision making can be accomplished by the accurate result of safety risk assessment.

  • This study is an empirical analysis of the cultural competencies of college students majoring in aviation services on their major satisfaction and professionalism. In order to focus on the cultural competencies of aviation service college students, who are rarely addressed in the preceding study and to see how cultural competencies have significant effects on their major satisfaction and professionalism, we divid them into six sub factors: willingness to participate, cognitive openness/flexibility, emotional control, patience with uncertainty, self-efficacy, and cultural empathy. And the mediated effects of major satisfaction on cultural competency and professionalism are analyzed to provide educational implications for cultural competency. Based on the results of this study, it is expected to apply to the education of aviation service-related departments, it will be a basic data to promote students' adaptation to the department and satisfaction of the department and to train global professional service personnel who can improve their post-employment work adaptability, job satisfaction, and service productivity.

  • 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.

  • Safety management paradigm which against human errors in aviation industry is now changing from the follow-up measures after accident in the past to systematic approach that a forecast the hazards and improve the working system of the group to prevent accidents. As human factors are based on the man's specific psychological traits, it takes much time and efforts to prepare the preventive measures. That's why aviation industry is interested in the accident-prevent measurements against human errors. In this thesis, therefore, we are going to introduce the efforts that aviation organizations have tried and recommend management systems and discuss the suggestive facts. At first, we discussed introduction of HFACS which is the systematic accidents-classification system related to human errors in the aviation organization and countermeasure in the aspects of management, technology/engineering, education training. We described about FOQA, LOSA, CRM/TEM, aviation safety information DB in the aspect of management, and explained safety technologies that prevent human errors or avoid technologically when emergency occurs in the aspect of technology/engineering. In the aspect of education training, we explained the application plan about safety programs(LOFT/Simulator use, CRM/TEM application etc).

  • The United Nations (UN) has tried to make international agreement to restrict artificial greenhouse gas emissions and the UN has concluded the UN Framework Convention Climate Change (UNFCCC) and the Kyoto protocol. Moreover, in 2012, the European Union announced that they will enforce the Directive 2008/101/EC. Therefore, after 2012, aircraft carriers that depart or arrive from EU will follow that regulation. For these reasons, Korea should prepare systematic and effective policy to reduce greenhouse gas emission from aviation activities. The purpose of this study is to find out effective measures to reduce greenhouse gas emission from aviation activities through research by countries all over the world. Here are the 4 measures to reduce greenhouse gas emission from Aviation activities that were found through research UK and Japan's policies. First, Korea should implement aggressive incentive policies. Providing proper incentive can attract voluntary participation of aircraft carriers to reduce greenhouse gas emission. Second, the government should adopt environmental tax on use of fossil fuels. Third, Korea should adopt the greenhouse gas Emissions Trading Scheme (ETS). Lastly, the Korea government should pull in with the international community to establish world-wide environmental policies.
