    Korean J Aerosp Environ Med 2010; 20(2): 43-52

    Abstract : Aviation medical examination is closely related to flight safety. The purpose of the periodic physical examination is to prevent incapacitation in the cockpit with potentially disastrous consequences to life and property. Aerospace medical association of Korea has the authority to review aviation examination reports. The board of aviation medical examination can decide to the waiver or defer cases. They can make a medical decision based on the guidelines for aviation medical examiners, but the guidelines are not in detail. References of foreign country’s manuals of aviation medical examination such as International Civil Aviation Organization (ICAO), Joint Aviation Authority (JAA), and Federal Aviation Authority (FAA) are often utilized. The purpose of this study was to compare the aviation medical guidelines and the regulations in pilots with coronary heart disease of Korea and other countries. There was no significant difference between the Korean aviation medical manual and the others including ICAO, especially in the case of coronary heart disease.

    Abstract : In 2009, the Republic of Korea accepted ICAO’s changes to Annex 1 and extended the retirement age of civilian pilots from 60 to 65 years of age. From medical examination data submitted to the Aerospace Medical Association of Korea for the issuance of aviation medical certification in 2012, data for pilots over 60 years of age has been reviewed. A total of 216 pilots (3.5%) over 60 years of age applied for the issuance of aviation medical certificate in 2012 and the average age for the 223 pilots is 61.6±1.4. Among the 216 pilots, 126 (58.3%) pilots were determined to be fit for a flight, 89 (41.2%) were determined to be waiver, and 1 pilot (0.5%) was determined to be unfit. The research shows that civilian pilots over 60 years of age have a higher rate of waiver than pilots below 60 years of age, which also indicates the higher probability of in-flight incapacitation. Therefore, age, health conditions, flight experience, development of flight environment, and aviation safety should be considered first and foremost when making aviation medical decision on civilian pilots over 60 years of age.

    Korean J Aerosp Environ Med 2018; 28(2): 23-29

    Abstract : Obstructive sleep apnea (OSA) is a breathing disorder characterized by a secondary intermittent decrease in blood oxygen saturation concentration, increased respiratory ability, and frequent awakening due to obstruction of airflow through repetitive upper airway during sleep. In adults, it is known to occur in 2 to 4% of the total population. In the case of obstructive sleep apnea without treatment for a long period of time, there is a decrease in working productivity due to daytime sleepiness and concentration problems. In addition, there are several types of serious complications, such as anorexia nervosa, related diseases, metabolic syndrome, etc. The National Transportation Safety Board (NTSB) reported a six-fold increase in the risk of aviation crashes for pilots with OSA. Based on this, the Federal Aviation Administration (FAA) is required to evaluate OSA on an aviation medical examination. OSA is an important issue directly linked to aviation safety. The purpose of this study is to evaluate the importance of the evaluation of obstructive sleep apnea in aviation medical examination and the evaluation method of OSA in foreign and domestic aviation medical examination.

    비행 중 조종불능상태

    Young Hwan Kwon, M.D.
    Korean J Aerosp Environ Med 2018; 28(3): 49-51

    Abstract : “Incapacitation” means any reduction in medical fitness to a degree or of a nature that is likely to jeopardize flight safety. Incapacitation of flight crew during flight is a serious threat to aviation safety. The focus of the periodic medical examination has been to detect medical conditions, and almost exclusively the emphasis has been on detecting physical medical conditions that may pose a threat to flight safety during the ensuing period of validity of the Medical Assessment. Therefore, the aviation medical examiner should be able to understand the incapacitation to utilize it for flight crew health evaluation and promotion.

    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.

    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.

    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.

    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.

    중대재해처벌법 시행에 따른 항공분야 위험성 평가 기법 연구

    Abstract : Currently, an important keyword for safety issues in Korean society is the enforcement of the Serious Accidents Punishment (SAP) Act. The purpose of enacting the SAP Act is to prevent accidents and disasters by establishing a system in which society, business, and organizations systematically manage safety and health. The mandatory measures for the enforcement of the SAP Act are to have manpower and budget necessary for accident prevention, and to establish and implement a safety and health management system. Measures concerning the establishment and implementation of the safety and health system begin with the application or risk management procedures to identify hazards, eliminate risk factors, and prepare control measures. In order to increase the validity of the risk management application results, it is important to apply a technique for risk assessment that systematically evaluates risk factors. Therefore, this study intends to examine the recent trends and implications of risk assessment techniques. First, based on the risk assessment guidelines of the MOEL in Korea, major risk assessment techniques were considered and examples were presented. The representative risk assessment techniques consider are 4M, Checklist, HAZOP (HAZards & Operability Studies), What-IF, JSA(Job Safety Analysis), FTA (Fault Tree Analysis), ETA (Event Tree Analysis), and CCA (Cause Consequence Analysis).
