Editorial for Vol. 32, No. 2
Abstract : In Vol. 32, No. 2, our journal prepared 3 original articles, 3 review articles, and 1 brief report. A Survey of the laboratory tests item was conducted during aviation medical examination based on the 27 hospitals. The following items were implemented in all institutions, but other items was different by institution. Urine test, ophthalmic test (except fundus test), fasting blood sugar, complete blood cell count, electrocardiogram, electoencephalography, chest X-Ray, pure tone audiometry, and total cholesterol. The impact of COVID-19 on the flight training of student pilots was analyzed through a survey. On the positive side, fewer commercial flights and fewer flights mean more opportunities for students to train. Fewer face-to-face classes have freed up more time for self-care. In other words, students were able to plan and control their exercise, self-study, rest, and sleep time on their own. On the negative side, social distancing prevented them from riding in the back seat, leaving them less chance to get used to the cockpit.

우주에서의 외과수술
Surgery in Space
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.

The Enhancing Error Management of Pilot and Line Operation Safety Audit
Abstract : The human factors become the most important factor in aviation safety. In order to prevent accident, pilots should manage errors in the cockpit. International Civil Aviation Authority (ICAO) recommends airlines to implement line operation safety audit (LOSA) to identify the management of errors by pilots and understand real errors and the competencies. The LOSA may provide metrics of the prevalence of errors by each types and rate of trapping errors to management enhancing errors. Airlines may understand how crew respond and manage errors. The operator may enhance safety once they identify errors and train crew how they manage to reduce the most mismanagement errors. This study is to provide operators eight recommendations on how to enhance errors and LOSA understanding human errors collected through LOSA and enhancing the implementation of LOSA with guidance according to ICAO and Federal Aviation Administration.

Big Data: An Overview and Its Applications in Medicine and Aviation
Abstract : 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.

Investigation of the Status of Laboratory Tests Conducted during Aviation Medical Examination
Abstract : Purpose: The medical certification for pilots is required by the aviation safety authority based with the aviation safety act. Methods: In this study, medical examination items of the year of 2021 performed during the aviation medical examination in Korea were reviewed by retrospective analysis. Results: Data from a total of 27 hospitals were collected. The number of inspection items ranged from a minimum of 22 items to a maximum of 57 items, showing a difference of more than double. Data from tertiary general hospitals and large airlines showed a tendency to perform more items of test compared to clinic-level institutions. The ratios for each inspection item are as follows: 1) 100% inspection items: urine test, ophthalmic test (except fundus test), fasting blood sugar, general blood test (complete blood count), electrocardiogram, electoencephalography, chest posterior anterior, pure tone audiometry, and total cholesterol; 2) 65%–74% inspection items: triglyceride, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, blood urea nitrogen/creatinine, and hepatitis B surface antigen; 3) 57% inspection items: hepatitis B surface antibody, human immunodeficiency virus, and venereal disease research laboratory; 4) 50% inspection items: urate and fundus examination. Conclusion: There have been many changes in the medical field over the past 40 years, but in terms of examination items, the aviation physical examination does not reflect the flow of change. Over the past years, the number of pilots has increased significantly, the flight environment has changed, and medical examination methods have been developed and diversified. In accordance with this, it is necessary to change the test items.

A Thought on the Flight Training of the Students in Department of Flight Operation under COVID-19
Abstract : Purpose: The COVID-19 pandemic has wide spread to aviation. This study was conducted to find out the perception of flight training for student pilots in the flight training center in a university with COVID-19 pandemic. Methods: It analyzed through qualitative research by aviation subject matter experts in Korea. Results: The advantages of COVID-19 were the increased flight training opportunities due to significant decrease of aircraft operations in the airports, reduced ground school hours due to Social Distancing concerns of infection, difficulty in communication due to wearing masks, difficulty in purchasing parts for the maintenance, deterioration of skills due to reduced face to face class hours, and laxity in lifestyle were found. Conclusion: It was analyzed that the longer the corona pandemic, the lower the motivation of students due to uncertainty in the job market.

Epidemiological Aspects of Tsutsugamushi Disease (Scrub Typhus) Outbreaks in Republic of Korea and Japan
Abstract : 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
