    항공계열 대학생의 자기관리역량이 사회불안에 미치는 영향

    Abstract : Purpose:This study is a descriptive research study that analyzed the effect of self-management competence on social anxiety in aviation-related college students. Methods: Data were collected from a total of 90 students, including 40 from the Department of Aviation Operations and 50 from the Department of Aircraft Maintenance Engineering. Results: The self-management competence of aviation college students was found to be 3.55 points, and social anxiety was rated at 2.02 points. The study categorized students into groups based on their self-management competence levels, revealing that the group with high self-management competence had the lowest social anxiety at 1.65 points. The middle group showed social anxiety at 1.99 points, and the group with low self-management competence exhibited the highest social anxiety at 2.51 points. The study identified a negative correlation between self-management competence and social anxiety, indicating that as self-management competence increased, social anxiety decreased. Examining sub-elements of self-management competence and their correlation with social anxiety, the study found that self-emotion awareness and social anxiety exhibited a positive correlation. Conversely, self-control, confidence, self-expression, perception of reality, independence, and social anxiety showed a negative correlation. Multiple regression analysis revealed that self-control had a negative effect on social anxiety, suggesting that strengthening self-management competence. Conclusion: In terms of self-control, strengthening self-management competence could reduce social anxiety among aviation college students.

    항공산업 분야 사전 안전성평가 및 컨설팅 제도 도입에 관한 연구

    Abstract : Purpose: In the aviation industry, safety is paramount, requiring airlines to obtain an air operator certificate and undergo regular risk assessments. Major airlines often use international organizations or consulting firms for these assessments, while low-cost and small aircraft operators face challenges due to high costs. In contrast, the maritime sector has comprehensive guidelines under the Maritime Safety Act, benefiting from safety diagnosis companies’ support. However, the aviation sector lacks detailed regulations and companies dedicated to safety diagnosis tasks, with only basic standards for aviation academic review institution personnel under the Airport Facilities Act. Methods: This study statistically analyzed 57 experts working in public institutions, research institutes, and academia, including airline employees, after conducting a survey on the necessity, method, and operation of the aviation consulting system. Results: As a result of the survey analysis, 96.6% of the respondents said the safety of the aviation industry as a whole could be improved by introducing a consulting system. Conclusion: Accordingly, it is proposed to introduce a private safety evaluation and consulting system to secure the safety of airlines, aircraft operators, and specialized educational institutions and to improve policy efficiency. This includes shortening the risk assessment period of the Ministry of Land, Infrastructure and Transport and the necessity and scope of delegating safety-related tasks to private institutions.

    Air Traffic Control Threats to Pilots through Line Operations Safety Audits

    Abstract : Purpose: The purpose of this study is to understand the air traffic control (ATC) threats that cause airline pilots to commit errors during normal operations by identifying the prevalence of ATC threats to reduce ATC communication errors for safe flights. This study deals with ATC communication threats effect on the human performance of pilots through LOSA (line operations safety audit) implemented by Airlines. Methods: This study deals with ATC communication threats effect on the human performance of pilots through LOSA implemented by two domestic Airlines. Results: The prevalence of ATC threats shows that there are 60% of flights with at least one ATC-related threat. The frequent ATC threats have been identified as difficulties in understanding controller accents, changes of the runway, errors by ATC controllers, difficult clearance of altitude change and multiple clearances in one call. The most prevailing ATC threats occurred during the Descend, Approach & Land phase of the flight. Conclusion: In order to prevent accidents related with ATC and improve threats and human errors in the actual environment of pilots, it is necessary to identify and analyze the actual threats and errors in the cockpit regarding ATC. It is required to improve the management of ATC threats proactively. According to LOSA result, ATC threats are a frequent threat to pilots, and the most frequent type of ATC for pilots is difficult Accent or language to understand controller. These findings could be trained in the simulators and cockpit in a similar environment and workload as in actual flight for effective countermeasures.

    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.

    저비용 항공사의 특성과 항공운송 시장 파급효과의 이론적 논의

    Abstract : Air travel market has changed significantly by the emergence of a low-cost 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.

    항공 피로위험관리를 위한 생체수리적 모델 접근 방안

    Abstract : In the aviation sector, it is recommended to adopt an aviation safety management system (SMS) from international organizations (International Civil Aviation Organization, Federal Aviation Administration, etc.) and to apply a related system in each organization. Among them, fatigue management recommends fatigue risk management system (FRMS) operating as part of SMS proactive risk management. Advanced aviation organizations are developing and applying various related risk assessment techniques that consider characteristics in order to apply scientific and systematic FRMS. Among which the biomathematical fatigue model (BFM) are representative. The Bio-mathematical Model is designed to represent the level by converting it into a simple numerical score, taking into account various related factors for the measurement object. The BFM is tool to predict the level of fatigue of the crew based on scientific understanding of the factors that contribute to fatigue. The Biomathematical Model is used as a scientific approach that promotes the transition to a performance-based safety management. In this study, the recent trends and implications for the BFM developed and applied in the aviation field are to be reviewed. First, FRMS was considered within the SMS framework, then the characteristics and application methods of the BFM were examined, and finally, the direction of the development of the BFM was suggested.

    최근 6년간 일개 병원의 외국인 환자 현황과 코로나19의 영향

    Abstract : Purpose: As it becomes difficult to move between countries due to the spread of COVID-19, it can be expected that the number of foreign patients entering Korea for treatment will decrease significantly. The purpose of this study is to investigate the current status of hospitalization of foreign patients over the past 6 years and the impact of COVID-19. Methods: The sex, age, nationality, and histories of foreign patients who visited the International Medical Center from 2016 to 2021 were collected. A total of 25,569 subjects were analyzed. Results: For six years from 2016 to 2021, the number of foreign patients increased steadily before COVID-19 but decreased significantly after COVID-19. Overall, it was analyzed that the average annual growth rate of foreign patients from 2016 to 2019 was about 6%. However, due to the impact of COVID-19, the number of patients in 2020 decreased by about 57% compared to the previous year and by about 1% in 2021 compared to the previous year. Conclusion: It is believed that the decrease in foreign patients in a situation such as Corona 19 is due not only to the risk of infection, but also to the difficulty of moving between countries. In other words, it can be said that the driving force for the movement due to the medical skill gap still exists. Therefore, if this situation improves, it is judged that the phenomenon of moving abroad in search of medical care is inevitable.

    우주에서의 외과수술

    Abstract : 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.
