    Korean J Aerosp Environ Med 2007; 17(1): 22-27

    Abstract : Background: Vestibular reflexes, such as vestibule-sympathetic reflex, have been considered as an important physiologic mechanism to maintain peripheral vascular resistance in case of orthostatic stress. Vestibular function may play an important role not only in maintaining spatial orientation, but also in determining G-tolerance. The purpose of this study was to investigate the possible contribution of vestibular function to G-tolerance. Methods: Vestibular function was measured indirectly in 86 subjects by analyzing vestibulo-ocular reflex (VOR) using a rotating chair test. They were also exposed to +6Gz acceleration for 30 seconds with rapid onset run (1 G/sec). After G-exposure, they were classified into the Pass and the G-LOC group according to their success or failure to maintain consciousness during G-exposure. The VOR parameters of the G-LOC group were compared with those of the Pass group. Results: While VOR gain values of one subset of the G-LOC group (low gain G-LOC group, N=8) were significantly lower than those of the Pass group at rotation frequencies of 0.02, 0.04, 0.08, and 0.32 Hz, VOR gain values of the other subset of the G-LOC group (high gain G-LOC group) were significantly higher than those of the Pass group at all rotation frequencies. There was no difference of VOR phase value between the Pass and the G-LOC groups. Conclusion: This study suggests the vestibular function may be involved in determining G-tolerance. According to VOR gain values, we were able to recognize two distinct G-LOC subgroups compared with the Pass group. The difference between afferent or efferent vestibular flows and target organ response can be a possible explanation for different VOR parameters of G-LOC subgroups.

    비행훈련 시 학생조종사 인적요인 영향에 대하여

    Abstract : Purpose: Most aviation accidents are caused by human factors, and in recent years in Korea, human factors have been identified as the cause of 70% of aviation accidents. Human factors that influence pilots in the aviation field are closely linked to judgment ability and are crucial factors directly impacting flight proficiency. Methods: To explore the human factors that may affect student pilots during flight training, a survey was conducted among flight instructors holding pilot certificates. Results: The results aim not only to identify the human factors that can influence flight performance during training but also to establish a direction for safety by addressing the human factors related to student pilots, with the goal of maintaining safety. Conclusion: Understanding the human factors that affect student pilots, who will be responsible for transporting hundreds of passengers in the future, is essential for cultivating safety knowledge and risk management skills, making it a highly important matter for accident prevention.

    항공학과 학생들의 MBTI 성격 유형별 조직몰입 및 팀워크 역량 차이분석

    Abstract : Purpose: For students who have already decided on their career path by entering the aviation departments, this study aims to analyze organizational commitment and teamwork relationships using the Myers-Briggs Type Indicator (MBTI) personality type as a tool. Methods: In order to investigate the career choices of aviation workers according to MBTI personality types, a survey was conducted targeting enrolled in and graduating from the aviation departments, and organizational commitment and teawork were analyzed using SPSS WIN 21.0. Results: Sening, Feeling, and Perceiving were mainly found in students who chose cabin crew as their career, whereas students in department of flight crew and aviation maintenance showed high level in Instuition, Thinkg, and Juding. As a result of the analysis, the MBTI type for each career path of aviation students was mainly ENTP for flight crew students, ESFP for cabin crew students, and INTP for aviation maintenance students. Conclusion: Even if students make their choice based on advice, subjective and objective judgments in choosing a career path, there are cases in which the chosen job does not suit them. Therefore, it is hoped that various indicators such as the MBTI will be used to help studnes choose their career path.

    Deterioration and Recurrence in Flight Passengers with Ischemic Stroke: An Evidence Based Case Report

    Abstract : Ischemic stroke is a cerebrovascular disease characterized by a sudden neurological deficit due to thrombotic or embolic event. The physiological changes during in-flight related to high altitude, hypobaric hypoxic, is a condition that can affect blood circulation in the brain. There was limited evidence to prove the possibility of clinical condition deterioration and/or new onset of recurrent stroke among commercial flight passengers with ischemic stroke. This evidence-based case report aims to determine the possibility of clinical condition deterioration and/or new onset of recurrent stroke on commercial flight passengers with history of ischemic stroke related to hypoxia hypobaric during the in-flight or post-flight period. Three relevant articles were found in PubMed, EMBASE, Cochrane, and Ingenta library databases. After critical appraisal, all of the relevant articles were shown to be valid, important, and applicability with the level of evidence ranging from III–IV. There were no studies that reported a clinical condition deterioration and/or a new onset of recurrent stroke among commercial flight passengers with ischemic stroke. However, two studies reported a new case of ischemic stroke during in-flight with unknown etiology. Commercial flight passengers with history of ischemic stroke didn’t show any clinical condition deterioration and/or a new onset of ischemi stroke during in-flight or post-flight.

    항공분야에서의 블록체인 기술 현황

    Abstract : Blockchain is a type of distributed database managed through multiple network transaction details (P2P, Peer to Peer), and transaction information is stored on multiple computers (nodes) connected to the blockchain network instead of storing it in one server. It is an algorithm that binds transaction details to form blocks, connects multiple blocks like a chain, and then copies and distributes them by a large number of people. In the case of the aviation industry, it is worth making full use of blockchain technology to revolutionize existing systems and business processes in terms of cost and transaction transparency, so blockchain can become one of the innovative technologies that will change the paradigm of the aviation industry. As the blockchain market is still in an immature stage and the development of technology is expected in the future, it is necessary to prepare support measures to lead and preempt the global blockchain market in the future through development support and cooperation that can be actively used in the field.

    SHELL 모델에 근거한 의료사고 인적요인 분석의 탐색적 연구

    Abstract : The SHELL (Software, Hardware, Environment, Liveware) model is one of the models for determining the cause of aviation accidents. The human factors of medical accidents are analyzed through the SHELL model. This study is a case study that analyzed a total of three cases, including two medical accident court precedents and one large fire at a medical institution. In the human factor analysis of cases 1 and 2, the main factors were that liveware (human) violated the duty of care and did not follow the guidelines of the institution. The large fire incident in the hospital in Case 3 was caused by a lack of awareness of the safety of managers, the installation of illegal facilities and environments, lack of medical staff’s response and training, and the condition of patients who were mostly elderly. The liveware at the center of the SHELL model is the most important human factor, and the environment, facilities, and equipment surrounding liveware must be supplemented to prevent future medical accidents.

    한국공군의 예측적 안전관리를 위한 FOQA 시스템 고찰 연구

    Abstract : In 1962, British Airways implemented Flight Operations Quality Assurance (FOQA) for the first time in order to reduce the rate of increase in aviation accidents, which could increase due to the expansion of the aviation industry and the increase in traffic. After that, in 1995, it was developed for the purpose of collecting/analyzing flight data on technical defects and dangerous situations that occur in actual flights through voluntary participation programs by U.S. airlines. In the private sector, it has been regulated and operated in most countries since early 2000 according to the recommendations of International Civil Aviation Organization (ICAO) and Federal Aviation Administration. In addition, civil airlines are required to conduct FOQA as part of Safety Management System in accordance with ICAO ANNEX-6. The U.S. Air Force benchmarks the FOQA safety program in the civilian sector and applies it under the name of Military FOQA. Therefore, in the Republic of Korea Air Force, there is a need to ensure flight safety in an objective and scientific way by deriving event parameters for the introduction of the flight data analysis system in order to perform predictive safety management in accordance with the trend of the times.

    The Improvement of Pilot Fatigue Management

    Abstract : The fatigue of pilots is the most threatening factor in aviation safety internationally, requiring continuous management. In order to prevent aircraft accidents that may occur due to fatigue, this paper analyzes fatigue-related accident cases and previous research and suggests ways to improve the fatigue management of pilots. Problems in major fatigue accidents were active communication failure, lack of leadership of the captain, inadequate contingency management, lack of workload management, and the most important factors in accidents were inadequate decision making of continuing an approach without going around. It is necessary to proactively improve and establish go-around culture in the organization and manage human factors with training and procedures of Threat and Error Management and Crew Resource Management. In order to fundamentally prevent accidents related to fatigue fundamentally, it is necessary to establish Fatigue Risk Management and Safety Management System, and identify the actual threats and errors in the cockpit of the aircraft.

    포스트 코로나 대비 항공종사자 건강증진 방안: 싱잉볼 명상을 중심으로

    Abstract : COVID-19 has severely impacted the aviation industry, with air travel declining sharply and airlines cutting capacity as a result. Additionally, many countries have closed their borders to block spread of the virus. Air traffic controllers and pilots have also experienced negative effects, in that the experience required to maintain proficiency has decreased over the past three years. This has resulted in financial problems for airlines and air traffic control facilities, leading to increased job uncertainty and a manpower imbalance. As air traffic volumes begin to increase again, air traffic controllers and pilots responsible for passenger safety may experience extreme stress and anxiety in new situations. To address this problem, healthcare methods are needed to help aviation professionals to overcome stress and reduce anxiety. Meditation can stabilize the autonomic nervous system, promote relaxation and comfort in the mind and body, and could aid in smooth metabolism by suppressing the sympathetic nerves that cause our bodies to feel tension and activating the parasympathetic nerves. However, achieving the benefits of meditation can require time and effort, and general meditation can be challenging for individuals experiencing physical pain. Therefore, singing bowl meditation is recommended, as it can easily induce a meditative state. The sounds produced by Tibetan singing bowls can promote meditation by tuning the alpha waves, theta waves, and gamma waves of electoencephalography. Singing bowl meditation is a beneficial method for individuals with limited time or physical disabilities due to work schedules, such as air traffic controllers and pilots, to easily access meditation.

    항공교통관제분야 교대근무자를 위한 피로관리 전략

    Abstract : Recently, shift work, including night shift, has been widely implemented in modern society. These include workplaces that have to work 24 hours a day for production processes, such as petrochemicals, power plants, and steel industries, as well as industries necessary to secure public services such as gas and electricity. In particular, workers in the aviation sector are mostly engaged in shift work due to the nature of their 24 hours of continuous work. Most shift workplaces comply with legal work regulations, but they fail to take into account workers’ fatigue and focus only on compliance with regulatory requirements. Specifically, shift work needs to provide minimum guidelines for workers’ safety and health. Therefore, this study analyzed and reviewed the current status of shift work in the air traffic control field, where shift work is essential, and presented guidelines for the safety and health care of shift workers. First of all, the international shift work guidelines and domestic laws related to shift work were reviewed, and the characteristics of the shift work system in the air traffic control field were reviewed. For the guidelines, we discussed the shift method, shift speed (direction), shift work hours and hours, night work, and other considerations.
