Air travel market has changed significantly by the emergence of a lowcost carrier (LCC). The LCCs offer lower fares and fewer frills than the traditional full service carriers (FSCs). The key competitive advantage of the LCCs is their ability to offer significantly lower fares, or at least to create the image of offering lower fares, while being able to generate profits by having low unit costs. LCCs have reshaped the competitive environment within air travel markets and have made significant impacts in the domestic passenger markets, which had previously been largely controlled by FSCs. The new demand for air travel experience through the low fares of low-cost airlines increases the likelihood of choosing not only low-cost airlines but also existing large airlines when choosing air travel. This generally equates to the intention of customers to move to more advanced products as their experience with new products increases. Therefore, the purpose of this study is to theoretically discuss the operating characteristics and market ripple effects of low-cost airlines, and to explore the theoretical implications of existing papers.

Purpose: The purpose of this paper is to study the epidemiologic series of Tsutsugamushi disease (TD), also known as scrub typhus in the Republic of Korea (Korea) and Japan. Methods: We investigated raw data of TD outbreaks from the National Notifiable Disease Surveillance System of the Korea Diseases Control and Prevention Agency in Korea, and the National Institute of Infectious Diseases in Japan, 2016 to 2020. Results: There were 36,785 cases of TD with a cumulative infectious rate (CIR) of 14.3 per 100,000 populations in Korea from 2016 to 2020. During the same period in Japan, there were 2,350 cases with a CIR of 0.4. When compared, Korea was much higher than that in Japan (P<0.01). In Korea, more females (60.2% of total cases) were infected than males (39.8%), while there was a significant difference between males (58.8%) and females (41.2%) in Japan, respectively (P<0.01). Conclusion: These differences in TD risk factors reflect differences of vectors/hosts, climate, and geographical and cultural characteristics between the two countries. The surveillance of TD, primarily a zoonotic disease, should be continued in order to obtain a better understanding of its current status. Moreover, guidelines for the prevention of TD, and its control measures should be more established. [ABSTRACT FROM AUTHOR]

As the number of passengers using aircraft increases around the world, there may be more medical measures needed within the aircraft. These medical measures may also include measures against serious situations such as cardiopulmonary resuscitation (CPR). However, since the environment is different from the hospital in the aircraft, it may be difficult to cope with such a situation. Moreover, such in-flight CPR may become more difficult at a time when the proportion of out-ofhospital CPR is decreasing due to the recent COVID-19 pandemic. In this paper, I would like to summarize how in-flight CPR is performed and review the main discussions on CPR in the COVID-19 pandemic, and finally suggest how to perform a safe CPR in the COVID-19 situation.

In Vol. 31, No. 3, our journal prepared three review articles, an original paper, and two case reports. First, as COVID-19 continues for a long time, aviation workers, including pilots, are also experiencing mental problems such as depression. Therefore, we have compiled the basic principles for improving the mental health of pilots. Next, it is difficult to properly perform cardio-pulmonary resuscitation (CPR) when a cardiac arrest situation occurs in an aircraft. Moreover, in the context of the COVID-19 pandemic, CPR is more difficult because medical staff and other passengers may also be exposed to infections. Therefore, we have summarized the principles of CPR on board and ways to perform CPR while keeping the safety of medical staff and other passengers in the COVID-19 situation. The sudden change of gravity caused by space travel has various effects on the human body, and among them, the effect on the immune system is profound. Therefore, we reviewed the research methods to study the effect of gravity on the immune system and the results. In addition, we analyzed the demographic characteristics and health status of immigrant visa applicants who intended to immigrate to the United States over the past five years. Next, through two case reports, we reported cases of determining physical fitness for aviation service in patients who recovered after receiving appropriate treatment for chronic myeloid leukemia or renal cell carcinoma.

The aircraft maintenance personnel qualification systems and trainings in Korea are constantly striving to meet the standards of the International Civil Aviation Organization (ICAO). However, Korean aircraft maintenance licenses are not recognized in most foreign countries. The reason for this is that the educational standards of the Korean maintenance training curriculum do not meet international standards such as those set by ICAO. Therefore, this study aims to examine the changing trend of The Korean aircraft maintenance qualification system and the current status of maintenance training through the study of international literature on ICAO, European Aviation Safety Agency, Federal Aviation Administration and previous studies in Korea. It will diagnose the problems and provide some suggestions on how to secure the international status of The Korean aircraft maintenance qualification system and the current status of maintenance training, and provide practical suggestions for fostering the aircraft maintenance technician.

Purpose: Shift work can have physical and mental effects by destroying the physiological rhythm cycle by working at a times that does not match the worker’s physical and daily life rhythm. Due to the nature of its mission, the Korean Air Force performs 24-hour shift work in various fields, and this study attempted to analyze the sleep quality and mental workload of air defense operation control personnel who require shift work. Methods: Three surveys were conducted to analyze fatigue and job difficulty, etc. A general questionnaire asking about mission-related experience and demographic characteristics, the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K), which measures sleep quality, and NASA-TLX (National Aeronautics of Space Administration-task load index), a subjective job difficulty assessment method. Results: Overall, there was no significant difference in the ‘total sleep index’ and ‘job difficulty’ as a result of comparing and analyzing the 5-team 4 shift method and other shift methods, but the ‘total sleep index’ score was analyzed twice as high as the reference score in both comparison groups. Conclusion: In order to prevent shift workers’ sleep-related fatigue and human errors that may arise from this, there is room for improvement in shift work, and as can be seen from the analysis results, it is necessary to manage the schedule by focusing on shift types rather than shift methods.

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. [ABSTRACT FROM AUTHOR]

Meteorological factors have a profound impact on aircraft operation and safety. Weather-related incidents accounted for 8% of all accident reports, according to data from the U.S. Federal Transportation Safety Commission’s 2009–2018 U.S. aviation accident/quasi-accident survey. The tendency of lightning strikes in domestic airports and surrounding areas is increasing year by year, but unlike major overseas airports, there is no official lightning warning system other than the radio wave system in case of lightning strikes from the Korea Meteorological Administration. Since each operator issues its own alerts based on the Significant Meteorological Information report, small agencies such as low-cost airlines have limited capabilities to mitigate lightning damage. This study aims to support the safety and smooth air traffic control of ground operators and aircraft through the introduction of lightning warning systems and equipment in Korea to protect ground workers and aircraft safety.

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.

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. [ABSTRACT FROM AUTHOR]

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).

Since its emergence in Wuhan, China, COVID-19 has spread and had a profound effect on the lives and health of people around the globe. Most people who develop COVID-19 fully recover, but current evidence suggests approximately 10% to 20% of people experience a variety of mid- and long-term effects after they recover from their initial illness. These mid- and long-term effects are collectively known as post covid-19 condition or "long COVID". Studies have shown that a significant number of patients complain of multiple symptoms over a period of several months or longer. The symptoms of long covid include fatigue or muscle weakness, dyspnea, cognitive impairment, and depression or anxiety. These chronic symptoms can also negatively affect aviation safety. Therefore, this review summarizes studies of the long-term effects of COVID-19, and aeromedical implications of long COVID. [ABSTRACT FROM AUTHOR]

Big data is a technology that processes a large amount of structured and unstructured data sets that are beyond the ability to manage data with commonly used data analysis methods. According to the amount and type of data is showing explosive changes, and the amount and type of data in the industry are also increasing remarkably. Now, how to extract meaningful information from the exploding data from those of data bunches and use it as valuable information is becoming a social task. In the existing traditional data, individual data itself was important, but big data must deal with a large amount of data and judge it from an overall perspective, so innovation of the existing data judgment method is needed. Big data has a common feature that can be called "3V": data volume, variety and velocity, because it is significantly different from existing traditional data handling method. Since the nature of big data has changed to the extent that it is impossible to smoothly collect and process it with existing technologies, various advanced big data processing technologies are needed to extract value. Big data is not a single technical item, but comprehensive technology in which various underlying technologies are fused. [ABSTRACT FROM AUTHOR]

For Mars exploration, spaceflight is advancing with the goal of sending manned spacecraft to Mars. Mars is 54.6 million kilometers away when it is closest to Earth. If a surgical emergency occurs during Mars exploration, it could take months or years to transport patients. Research estimates that an average of one surgical emergency will occur every 2.4 years during the Mars expedition for a crew of seven. Considering the astronomical cost of space travel and astronaut training, surgical treatment needs to be considered. There are various problems in performing surgery in space, but typically, physiological changes in the body due to microgravity, difficulty in performing surgery due to an unfamiliar environment, and difficulty in maintaining sterility can be considered. Also, since an experienced surgeon cannot ride on all spaceships, tele-surgery is required. As an alternative to overcome these problems, robot assisted minimal invasive surgery has been proposed. However, it is necessary to solve the signal delay caused by the longer distance. Other alternatives, such as the development of Robot technology, rapid transport due to trauma pod, and performing surgery while notifying the crew medical officer, have been suggested.
