Flight instructors at aviation training centers are exposed to various stresses, such as stress caused by special work environments, stress caused by working conditions, and stress related to uncertain future airline employment. These stresses are expected to not only affect flight safety, but also adversely affect the job satisfaction of flight instructors, and consequently negatively affect the performance of high-quality flight education. Therefore, this study was conducted to understand the effects of these stresses on the job satisfaction of flight instructors by examining the stress experienced by flight instructors in flight, psychological, and physical aspects based on the results of previous studies on stress. To the end, this study conducted a survey of flight instructors belonging to aviation training centers, and as a result of analyzing the collected data, it was confirmed that the physical stress of flight instructors had a significant negative effect on their job satisfaction.

This study intends to present the UAM pilot qualifications and training and education systems based on the roadmap of technology for K-UAM operation system, which is being promoted for commercialization in 2025. There are currently about 250 eVTOL manufactures around the world, and they are gearing up to produce a variety of UAM aircrafts. In Korea, 35 companies including Hyundai Motor company, Korean Air, Lotte and SKT are accelerating the development of UAM aircrafts. UAM is being developed as a public goods concept centered on public transportation and urban aviation rather than private transportation. Therefore, the UAM pilot qualification and education and training system should be suitable for operations in densely populated areas and complex urban enviroments. In other words, in order to ensure safe UAM operations, the competencies and qualifications of UAM pilots should be clearly established.

This paper proposes a UAV equipped with an automatic control system for educational purposes such as navigation flight or autonomous flight. The proposed UAV is capable of automatic navigation flight and it is possible to control more precisely and delicately than existing UAV which is directly controlled. And it has the advantage that it is possible to fly in a place out of sight. In addition, the user may arbitrarily change the route or route information to use it as an educational purpose for achieving the special purpose. It also allows you to check flight status by shooting a video during flight. For this purpose, it is designed to check the image in real time using 5.8GHz video transmitter and receiver. The flight information is recorded separately and used as data to judge the normal flight after the flight. The result of the paper can be flighted along the coordinates specified using GPS information. Since it can receive real-time video, it is expected to be used for various education purposes such as reconnaissance of polluted area, achievement of special purpose, and so on.

A comprehension-based computational model of pilot action planning called ADAPT is presented to model pilot performance in a flight simulation context. Individual pilots were asked to execute a series of flight maneuvers using a flight simulator, and their eye-scanning, control movements, and flight performance were recorded in a time-synched database. Computational models of each of the 25 individual pilots were constructed, and the individual models simulated execution of the same flight maneuvers performed by human pilots. The time-synched eye-scanning, control movements, and flight performance of individual pilots and their respective models were compared to test ADAPT's predictive validity.

This paper examines how macroeconomic variables, such as interest rate differences, inflation, exchange rates, economic growth and external debt growth, affect capital flight in the ASEAN-8 countries. We apply a panel data model with fixed effect estimation for the data for eight countries from the period 1994 to 2018. We use the residual approach used by the World Bank to measure the value of capital flight. The results show that the interest rate differences, exchange rates, economic growth and foreign debt growth had a positive and significant effect on outward capital flight. A further implication of this finding is that the interest rate differences, exchange rate, economic growth and foreign debt growth are factors that trigger an increase in capital outflow in the ASEAN-8 countries. Nonetheless, inflation rate is not considered to be the main factor influencing capital flight, as average inflation in the ASEAN-8 countries remains relatively stable. This paper will be beneficial for policymakers in the ASEAN-8 countries and encourage them to constantly pay attention to these four variables, as they significantly influence capital flight, whereas they can disregard the impact of the inflation variable that is not significant in influencing capital flight.

Objective: The purpose of this study was to investigate the feasibility of a new vault technique through a kinematic comparison of the YANG Hak Seon and Yeo 2 vaults. Method: The photographic images of the YANG Hak Seon and Yeo 2 vaults were collected using a high-speed camera, and their kinematic characteristics were analyzed using three-dimensional image analysis. Results: During the post-flight phase of the Yeo 2 and YANG Hak Seon vaults, the time of flight, height of flight, and flight distance were similar. At the peak of the post-flight phase, the trunk rotation angle of the YANG Hak Seon vault rotated $457^{\circ}$ more than did the Yeo 2 vault. During the post-flight descending period, the twist velocity of the trunk was much faster with the YANG Hak Seon vault ($1,278^{\circ}/s$) than with the Yeo 2 vault ($1,016^{\circ}/s$). Conclusion: To succeed in the new technique, the average twist velocity during post-flight must be maintained at $1,058^{\circ}/s$ and the twist velocity must be increased from the ascending phase.

현재 항공 산업 분야에 우수한 조종사를 공급하기 위해 전 세계적으로 전문교육기관 제도 (ATO; approved training organization)를 활용하고 있다. 세계적으로 활용되는 이 제도는 각 국가에 맞는 실정으로 변형되어 활용되고 있다. 본 연구에서는 우리나라 조종사 양성 전문교육기관의 운영방식 및 교육 환경을 자세히 살펴보고, 국제민간항공기구의 국제표준, 미국, 유럽, 캐나다 등과 일본, 중국, 싱가포르 등 주변국의 비행 교육기관 운영방식 및 비행교육 환경을 비교하여 차이점을 도출함으로써 우리나라 전문교육기관 제도와 어떠한 차이를 보이는지를 비교하였다. 이러한 비교자료를 기반으로 해당 업무 종사자들의 설문 조사를 통해 국내 항공안전법 전문교육기관 지정기준에서 설정하고 있는 학과 수업 양에 대한 만족도가 설문대상의 특성에 따라 큰 차이가 있었고 학과 수업과목에 따라 중요도의 차이가 발생하였다.

현재 항공기 조종사들이 사용하고 있는 항공기동 도해도 방법은 2차원 공간 표현만을 사용하여, 3차원 정보 입력 시 한계가 있고 이를 직관적으로 이해하는 것이 어렵다. 이를 위해 도입된 항공기동 애니메이션 저작도구들은 사용법이 복잡하고 중간에 비행경로를 수정하거나 다수 비행객체들의 전투 상황을 실시간으로 인터렉티브하게 다룰 수 없다. 본 연구는 항공기동 교육을 위한 애니메이션 시스템 중 3차원 항공경로 생성방법에 관한 것이다. 본 연구에서는 2D 도해도에 스케치된 초기 입력과 실제 항공기 추력을 계산하여 실제 비행과 유사한 3차원 선형 스플라인 곡선을 생성해 낸다. 제안하는 선형 스플라인 곡선 생성 방법을 이용하여 항공기동 브리핑 및 디브리핑 시에 비행경로를 실시간으로 생성 및 수정하는 것이 가능하고 이를 애니메이션으로 즉시에 표현할 수 있다.
