All around the world, numerous scientists have been carried out researches of e-Science to improve performance of computations and accessibility of their experimental flexibilities for a long times. However, they still have been in difficulty securing high-performance computing facilities. In case of Aerodynamics, for example, a single experiment costs a tremendous amount of budget and requires a span of more than 6 months even though researchers have been developed diverse improved mathematical methods as well as relied on advanced computing technologies to reduce runtime and costs. In this paper, we proposed a multiple infrastructure-based scientific workflow environments for engineering education in fields of design optimization of aircraft and demonstrated the superiority. Since it offers diverse kind of computing resources, it can offer elastic resources regardless of the number of tasks for experiments and limitations of spaces. Also, it can improve education efficiency by using this environment to engineering education.

Due to the increased leisure time, national income levels, and increasing the desire for new experience, interest causes increasing demand for recent aviation leisure sport. This leads to the need for a competitive foundation of the expansion of aviation leisure sports market potential. In 2014, the MOLIT(Ministry of Land, Infrastructure and Transport) created definition of sport and recreational aviation industry in the Aviation Act. The most significant change in Aviation Act related to sport and recreational aviation, it allows easier access for those wishing to participate in the joy of flight and also creating a sport and recreational aviation business market expansion. Therefore, in this paper, by analyzing the trend of foreign policy trends and domestic policies that sport and recreational aviation has been enabled, it is trying to present the activation policy proposals of sport and recreational aviation that is suitable for Korea.

AeroMACS spectrum is a national resource internationally allocated by ITU at WRC-07. AeroMACS is an airport broadband mobile communication infrastructure based on WiMAX-based IEEE 802.16e that enables real-time video, graphics, voice, and high-speed data transmission. With the approval of ICAO's development technology standards in 2008, 50 airports in 11 countries have already completed the testing of D-TAXI or A-SMGCS technology using the AeroMACS infrastructure in 2019, starting in the United States in 2009. With many advantages in safety and convenience in terrestrial telecommunications operations, the system is becoming an area of performance improvement for airport operations in accordance with ICAO's ASBU plan. This paper examines the current status of domestic development of AeroMACS and lists service areas applicable to airlines and operators. It also seeks to promote safe and efficient next-generation airport mobile communication system services by presenting feasible partners management in the mobile area and use of aircraft communication systems for active technology development.

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.

Cyber attacks on aircraft and aeronautical networks are not much different from cyber attacks commonly found in the ground industry. Air traffic management infrastructure is being transformed into a digital infrastructure to secure air traffic. A wide variety of communication environments, information and communications, navigation, surveillance and inflight entertainment systems are increasingly threatening the threat posed by cyber terrorism threats. The emergence of unmanned aircraft systems also poses an uncontrollable risk with cyber terrorism. We have analyzed cyber security standards and response strategies in developed countries by recognizing the vulnerability of cyber threats to aircraft systems and aviation infrastructure in next generation data network systems. We discussed comprehensive measures for cybersecurity policies to consider in the domestic aviation environment, and discussed the concept of security environment and quick response strategies.

As urban traffic congestion and environmental pollution are becoming significant issues in major cities, Urban Air Mobility (UAM) is gaining attention as an efficient solution. In this study, we conducted a geographic information system (GIS)-based spatial analysis and clustering algorithm considering the actual data of the terrain and infrastructure in the Busan area, through which we were able to select the location of vertiports and corridors (flight routes) for the UAM operation. Based on the Gimhae International Airport, which is expected to be the center of the UAM infrastructure system in the Busan region, we judged that three vertiport locations in the target area were suitable. Subsequently, we used the A^* (A-star) algorithm considering Ground Risk to select a flight path that minimized both risk and distance. Through this, we confirmed a risk reduction effect of 80.168% compared to the minimum distance route.
