While various efforts are being made to ensure aviation safety, air accident rate induced by pilot human factors is still high worldwide. In particular, among pilot human factors, it would be the most important issue for pilots to anticipate and recognize flight environmental factors beyond their control and to make a positive decision making(ADM). In the Republic of Korea Air Force(ROKAF), there were many dizzying experiences induced by bird strike incidents and developed into dangerous moments such as damage to the aircraft and pilots' increased mental stress. It is a matter of serious concern in terms of safety management and human factors to dismiss bird strike incidents as inevitable misfortune due to environmental factors. In 2018, the ROKAF Aviation Safety Agency(ASA) conducted an experimental study to enhance pilots' ADM competence that can anticipate and avoid a bird strike. As the way of the study, 'Bird Strike Preventing Information' had been written and distributed every week by the ASA to flight units in the ROKAF during the period of the study. Through enhanced pilots' perceptual ADM competence, there was a noticeable number of reduction in bird strike incident compared to previous years of the experimental study.

It is necessary to establish a UAV pilot license and training system because the number of UAV-related accidents has rapidly risen. Most of accidents are caused by the human factors such as the lack of control skill and aviation knowledge. In this paper, we investigate licensing policy of small UAV pilots and examine the level of UAV licensing system and classification criteria based on comparative analysis of national cases such as USA, UK and China. Recently, the Ministry of Land, Infrastructure and Transport Affairs is planning to improve the safety regulation by taking into account the risk level of the licensing system, which has been classified according to the existing weight and commercial purpose. From the comparative analysis, we suggested a improvement policy for UAV licensing system in the view of pilot license segmentation, beyond Visual Line-of-sight flight and high risk UAV for non-commercial.

In aviation, it is important to analyse and classify human error in detail. Because human error has been implicated in 70 or 80% of aviation accidents in literature review. But, there is little detailed classification and research of human error. In this study, Objectives are to establish human error model by classifying types of human error in detail and also to analyse human factors by using the established model. Analysis of the data uses Korea Aviation Incidents Reporting System(GYRO). The resulting from actual analysis, there is a some difference between flight steps for human error occurrence and types of human error are different according to the aviation personnel(pilot, ATC controller).

Flight safety in modern commercial aircraft depends on the ability of pilots to manage overall flight operations. ICAO has made it mandatory for airlines to adhere to Crew Resource Management(CRM) policies to reduce operational safety threats. CRM is a set of techniques designed to effectively manage the human resources, aircraft, and environmental factors in order to promote safety and enhance efficient air operations. When looking at the career backgrounds of new pilots joining the Republic of Korea's commercial airlines, discharged military fighter pilots represent the largest demographic. Fighter pilots are experienced in empowering leadership and directive leadership from their military training and culture. New commercial airline pilots with military fighter pilot training should effectively acquire the required civil aviation CRM skills. The present study has been carried out to determine how the leadership experience of this demographic affects the acquisition of CRM skills for commercial airlines, and it confirms that there is a positive correlation.

Aircraft and the three-dimensional environment in which they operate are not user-friendly for human beings. As a result, maintaining the proficiencies necessary to safely and efficiently fly an airplane are difficult, and costly. The physiological and emotional status of the human element remains crucial in maintaining safe performance by all crew members. In the study of Hagiwara et al.(1993). they called the physiological and emotional status of the human element into the human alertness or physiological activity and stress, fatigue, circadian rhythm, alcohol. smoking, and self-medication are known the major factors that deteriorate the human alertness. Accordingly. this paper deals with the quantitative and objective performance test based on tracking error and reaction time by means of the new computer test program into which the perception-motion system of human beings is applied. Throughout this experiment using performance test, the results suggest that performance capability in state of sleep deprivation 2 hours and alcoholic 0.05~0.06% in blood were more impaired than one in a normal state, and they further showed statistically significant differences between them, which were influenced by impairment factors of body regulation and pilot's grade. We also obtained the prediction value and the 95% confidence interval of tracking error and reaction time at the normal state for the purpose of distinguishing performance capability between the normal state and the abnormal state. And it is expected that the evaluation of human alertness using performance test will be applied to the quantitative assessment of an each pilot's realistic consciousness/attention, and will lead a flight commander to the accurate decision of mission approval prior to a flight.

The purpose of pilot clinical trial is to evaluate the efficacy and safety of acupuncture therapy on TEWL(Transepidermal Water Loss) and skin hydration. A total of 36 human who visited Dongshin University Oriental Medical Center from October 2nd, 2015 to July 31st, 2016 were included in the pilot clinical trial. Acupuncture therapy was performed at Gokji(LI11) and Daechu(GV14). We observed change of TEWL(Transepidermal Water Loss), skin hydration before and after acupuncture therapy. In the primary endpoint, index of TEWL showed a statistically significant decline($8.01{\pm}2.55{\rightarrow}6.58{\pm}1.97g/h/m2$, $7.40{\pm}2.65{\rightarrow}4.99{\pm}1.89g/h/m2$). Index of skin hydration showed statistical significance($52.83{\pm}6.53{\rightarrow}56.82{\pm}7.24$, $63.50{\pm}8.57{\rightarrow}64.96{\pm}8.48$). To evaluate the safety, vital sign check were conducted and showed no statistically significant result. And there were no severe adverse events during this study. According to the above pilot clinical trial, it is suggested acupuncture therapy were effective for skin moisturizing.

An airman licensing system is central to the establishment and management of a state's airman licensing which gives official privileges to a person to perform specific activities by evaluating applicant's knowledge and proficiency. In recent decades, the level of the domestic aviation industry continues to leap forward and state's airman licensing system has also been advanced. However, accidents caused by pilot human errors are still occurring. In particular, the pilot occupations require a lot of experience and knowledge and the student pilots receiving the initial flight training have formed their own flight habits based on knowledge, skill, training methods, procedures, etc learned from the flight instructor. This paper discusses possible ways on the improvement for the domestic flight instructor rating by analyzing domestic and international rules and procedures for a flight instructor rating.

The pilot's aeronautical decision-making during the flying greatly affects flight safety, and the importance of situational awareness has been greatly emphasized as a prerequisite for making the right decision. This is the reason why more research and interests are needed to help students entering the pilot training program develop excellent situational awareness from the initial stage of training. Situational awareness is closely related to long-term memory activities in human information processing, and pedagogy and cognitive psychology have emphasized the encoding techniques as an effective long-term memory method. This study was conducted to confirm whether pilot students' using the encoding techniques to learn flight education materials in the early stage of their training at domestic universities has a positive effect on improving their situational awareness.
