This paper describes generic cognitive aspects of the air traffic controller's performance and perceptive activities unveiled through the past literature study. which underlines mental modelling and mental picture presented in the middle of complicated situational awareness and decision making process when air traffic controller comes to determine the distance between aircraft under control to maintain air traffic in a safe, orderly and expeditious way. It also describes human limit in terms of human memory in conjunction with relative workloads and environmental factor. In conclusion, It suggest that ATC authority will take into account the qualitatiive adjustment of training requirement necessary for ATC facility rating and refresher training to allow them more preparedness for better situational awareness and optimal decision making. In this paper controller's behavioral activators affecting their job performance are addressed in perspective of aviation safety.

Obstacle Limitation Surfaces (OLS) are set to protect a certain amount of airspace to limit objects, such as building, other structures, penetrating OLS for safety and regularity of aircraft operations in the vicinity of aerodromes. However, many civil petitions have been raising for effective utilization of lands and permission of building construction which penetrating OLS. While Republic of Korea are limiting installation of penetrating objects based on the National law of airport facilities, such objects are possibly permitted, only if, the possible risks coming from objects are acceptable or negligible in terms of safety and regularity in aircraft operations through the evaluation process, called as an aeronautical study. However, many countries are currently applying their own criteria, processes resulting in failing secure reliable results in aeronautical study. This research aims to establish the framework on criteria, process, and methodologies how the aeronautical study works including work flows between many stakeholder and responsibilities to be specified in national regulation system.

도심항공교통은 다수의 전기추진 수직이착륙 항공기가 이착륙 가능한 버티포트가 필요하다. 빌딩풍은 고층건물 주변부에서 발생하는 강풍으로 항공기 이착륙과정에서 항공기의 비행 안전성을 크게 훼손시킬수 있다. 본 연구에서는 항공기 이착륙시 발생할 비행안정성 분석을 위하여 먼저 빌딩풍 주변의 유동특성을 분석하는 연구를 수행하였다. 유동해석은 상용CFD 소프트웨어인 SimericsMP를 사용하였으며, 난류 모델은 k-ε RNG 모델을 사용하였다. 해석방법의 타당성을 검증하기 위하여 CAARC 빌딩모델의 표면 압력 계산결과를 풍동시험 결과와 비교⋅검증하였다. 두 개의 고충빌딩이 있는 상황을 가정한 후, 빌딩풍이 빌딩 주변부의 속도분포 변화에 미치는 영향을 분석하였다. 두 개의 고층 건물 사이의 거리가 증가하는 경우 와들 사이의 상호작용이 감소하는 것을 확인했다. 향후 본 연구를 확장하여 다양한 형상의 고충건물이 밀집해 있는 도심지역에 대한 유동해석 연구를 진행하고자 한다.

This study develops a forecasting method to estimate air cargo demand from ICN(Incheon International Airport) to all airports in EU with Seasonal Autoregressive Integrated Moving Average (SARIMA) Model using volumes from the first quarter of 2000 to the fourth quarter of 2009. This paper shows the superiority of SARIMA Model by comparing the forecasting accuracy of SARIMA with that of other ARIMA (Autoregressive Integrated Moving Average) models. Given that very few papers and researches focuses on air route, this paper will be helpful to researchers concerned with air cargo.

According to the statistics of the Ministry of Land Transport and Transportation in 2018, the average annual average number of air traffic users for has increased by 5.07% for domestic flights and 8.84% for international flights. Korea is facing a steady rise in demand from foreign tourists due to the Korean Wave. At the same time, a new lifestyle that values the quality of life of individuals is taking root, along with the emergence of LCC, and Korean tourists' overseas tours are also increasing, so improvement and expansion of domestic airport passenger terminals is urgently needed. it is important to develop a structured airport infrastructure by making efficient and accurate forecasts of aviation demand. in this study, based on the Big Data, long-term domestic and international demand forecasts for urban airports were conducted.. Domestic flights will see a decrease in the number of airport passengers after 2028, and international flights will continue to increase. It is imperative to improve and expand passenger terminals at domestic airports.

Student pilots receiving flight education are inexperienced in piloting and situation judgment skills and are greatly affected by various factors such as psychological, physical, and environmental factors. In particular, one of the most influential factors in the flight education of student pilots is the weather conditions. Unlike large aircraft used in the air transportation business, small aircraft used for flight education have a great impact on education, such as flight restrictions depending on weather conditions, psychological pressure in severe weather, and deterioration of student skills. Therefore, in this study, the meteorological characteristics of meteorological factors that have a great influence on small aircraft were analyzed. As a result of the analysis, an efficient and safe training operation method was suggested to a professional pilot aviation training organization through the adjustment of the training period for the season, the increase in aircraft operation rate, and a safe solo flight plan considering the weather.

This paper investigates the effectiveness of flight operation between airplane maintenance engineers and pilots who work together. The developed model is to identify the relationship between the attitudes of airplane maintenance engineers and pilots and the effectiveness of flight operation. The results indicate that the shared values and balanced power between airplane maintenance engineers and pilots are positively related with trust and job satisfaction, but conflict is negatively related. Further, trust and job satisfaction positively affect the effectiveness of flight operation. These findings suggest that the improvements of the relationships between airplane maintenance engineers and pilots need more efforts to ensure the aviation safety and efficient flights.

최근 전동킥보드 보급이 이루어지면서 이와 관련된 교통사고가 증가하고 있다. 이에 따라 전동킥보드 주행 시 헬멧 착용을 의무화하는 도로교통법 개정안이 시행되고 있지만, 물리적으로 대부분 현장에서 단속이 어렵다. 본 논문에서는 딥러닝 영상인식 기술을 활용한 객체검출(object detection) 모델인 YOLOv4를 기반으로 전동킥보드 사용자의 헬멧 미착용 검출시스템을 제안하였다. 이를 통해 전동킥보드 주행 시 헬멧 착용 여부를 효율적으로 단속하는데 활용 할 수 있을 것으로 기대한다.

This study is a study to secure accessibility in isolated, neglected and underdeveloped island areas. Theoretically explored ways to utilize UAM(Urban Air Mobility), which has recently attracted attention. This is a study for the important accessibility that is connected to the basic life of island residents. In particular, sufficient preparation time is needed, such as the selection of topics necessary for the change of the transportation service system for access to the island area, the public debate process, and the trial service period. Therefore, the secondary purpose of this study is to provide relevant basic data.

산업의 고도화에 따라 시간을 절약하고 공간을 활용하기 위한 방법으로서, 보다 큰 항공기, 보다 빠른 항공기에 대한 요구가 꾸준히 제기된다. 최근 불거진 지구온난화에 대한 이슈는 모든 산업의 초점을 친환경으로 돌려고 있어서, 항공기산업의 경우에도 예외 없이 보다 친환경적이고, 연료 효율적인 항공기개발에 집중하고 있다. 또한, 과거에 비해 자유의지가 강조되는 현재에는 보다 이용이 간편한 개인용 항공기의 출현이 요구되고 있어 이 분야에 대한 연구도 활발히 진행 중이다. 이에 따라 많은 국가들이 각각의 요구에 따라 초대형여객기(VLCT), 차세대 초음속여객기(HSCT), 그린항공기, 개인 자가용 항공기(PAV) 등의 형태로 개발을 서두르고 있으며, 일부 분야는 이미 상용화를 눈앞에 두고 있다. 특히 PAV의 수요는 향후에 자동차 시장의 일부를 대체할 것으로 예상되는 만큼 선진국들은 수요자의 요구에 따라 발 빠르게 대응하여 PAV에 대한 투자를 아끼지 않고 있다. 따라서 본 연구에서는 미래형 항공교통수단의 개발전망과 동향을 분석함으로써 앞으로 우리나라 항공기산업의 발전방향에 대한 시사점을 도출하고자 하였다. 특히 틈새 시장으로서의 PAV 분야의 개발동향과 전망을 살펴봄으로써, 동 분야에 대한 연구개발과 투자를 통한 우리나라 항공기산업의 발전기회를 모색해 보고자 하였다.
