Technological advancement and demand of sUAS (small Unmanned Aircraft System)are rapidly growing, which makes the current legal system unable to follow. Currently, Aviation Security Act and its subordinate law exclude the registration and certification for non-commercial purpose sUAS weighing less than 12kg. Despite this sUAS being the most popular model for consumer, there is no way to regulate them legally. When there is sUAS crash accident, the operator legally responsible for the occurrence damage cannot be identified. It has been an issue for a long time with the concrete classification and registration of sUAS, but it has not been introduced yet. It is obvious that damages caused by sUAS will be transferred not only to operators but also to third parties. Discussions on liability insurance for these sUAS are actively being held. But first, it is necessary to identify who will be responsible for the damage caused by the sUAS. In other words, even with the liability system established, without clarified operator the damage occurred cannot determine who is responsible. According to the cases of America and Germany, they have enforced the law of registration and identification obligated to 200g or 250g sUAS. Therefore, it is necessary to prepare regulations on concrete classification and registrations to identify for noncommercial purpose sUAS as soon as possible in Korea.

In 2017, the world's first WIG ship (WIG: Wing In-Ground) pilot's license written test was conducted in Korea. The WIG ship is a ship that combines the characteristics of ships and airplanes. Therefore, the pilot of the WIG ship was allowed to apply only for those who had the aircraft pilot's license and the 6th class marine nautical license. The WIG ship pilot's license system was first introduced by Korea, so there are no international standards for the license system, and the introduction of a domestic qualification system also requires institutional arrangements due to various restrictions such as pilot training. However, in order to become a valuable industry as a future growth engine for the ocean, several urgent problems need to be solved, and that is the training of manpower for WIG ships. Therefore, I reviewed the institutional issues related to pilot training as this subject. Since 2001, various countries around the world have been discussing this issue, centering on IMO, and Korea has continued to participate and cooperate in IMO meetings. And the national qualification test for surface flying ships was conducted in Korea from 2011. However, there are still problems to be solved, and I pointed out the advancement of the manpower training system, the education and training system, and the designated national educational institution system. As a solution to this, it was suggested through the improvement of the license system and the operation of designated educational institutions. Among these solutions, I believe that the best way is to entrust the operation of designated national educational institutions to private educational institutions. However, I propose a plan that the government entrusts to private educational institutions, but the government is responsible for licensing and supervision. WIG ship will be a new market for the aviation industry and aviation workers.

Surprise and Startle are often cited as potential or contributing factors in the cause of aircraft accidents because they can negatively affect pilots' situational awareness and decision-making. Accordingly, it is necessary to more clearly understand the effect on flight safety through the psychological and physiological reactions that occur to the pilots. Therefore, this study empirically analyzed the effects of Surprise and Startle on the pilot's psychological and physiological responses using a helicopter flight training device for the first time in Korea. As a result of the analysis, the ratio of recognition of Startle and Surprise, heart rate, and respiration rate showed a high difference between private pilots and commercial pilots. This is analyzed as the difference between long-term flight experience and flight time. In addition to presenting effective information for improving the education and training field of helicopter pilots in the future, it is intended to provide basic data for related research.

With the recent increase in interest in metaverse in which virtual and physical spaces are digitally fused, many activities in physical spaces are expected to take place in web-based virtual spaces. Therefore, there is a need for research on a self-sovereign identity system that can secure privacy and mutual trust in a DID(decentralized identifier)-based virtual space environment. We, in this paper, developed and validated a reliable communication method consisting of DIDComm messages, a procedure for generating distributed identifiers, asymmetric keys, and DID documents based on Hyperledger Indy and DIDComm open sources. The developed communication method can be applied to verify each other by exchanging additional information and verifiable credentials for trust among communication participants.

An empirical analysis was conducted on the workload of helicopter pilots flying in high-risk flight environments such as ground obstacles and weather effects at low altitudes. To evaluate the workload, an independent sample t-test was performed using the NASA-TLX evaluation method most suitable for the aviation field, and the workload score was calculated by applying the analytical stratification method (AHP) to compare and analyze private and commercial pilots. There is a significant difference in mean between private and commercial pilots and the result of work load was obtained over 70%. This paper studied the 'surprise and startle effect' on the helicopter field for the first time. In the future, it is intended to contribute to the safe operation of helicopters by presenting a method for effective safety management by utilizing it in the field of education and training for helicopter pilots and providing basic data for preventing accidents caused by human error.

DO-330 Software Tool Qualification Considerations is a guideline for development of tools used to develop/verify software and hardware installed on aircraft. And among several processes, the verification process is very crucial as it occupies a large proportion for DO-330. Especially, in order to qualify tool with high safety level, test objectives must be performed with independence, accordingly, more time, cost, and manpower are required than other objectives. In addition, even if the test cases or test procedures are well defined, the higher the complexity of the test the higher probability of human error occurs. In this paper, we propose Script-based Test Automation Agent software structure for efficient DO-330 verification process of A661UAGEN tool developed by Hanwha Systems. Compared to the test performed manually by the test engineer, testing time of the Script-based Test Automation Agent is reduced by 87.5% and testing productivity is increased by 43.75%.

The International Convention on Standards for Training, Certification, and Watchkeeping of Seafarers (STCW) outlines the qualifications that maritime cadets must meet in order to serve as merchant marine officers. Maritime English is one of the most essential qualifications for STCW, and each national authority is implementing Maritime English education that complies with national and international regulations. In this study, an English proficiency background survey was conducted to investigate the factors related to the Maritime English skills and competencies. In line with this, maritime cadets utilized the Standard Maritime English Communication Phrases (SMCP) learning platform to track their learning progress and its efficacy. This study examined the applicability of the automatic scoring platform for Maritime English education, as well as its future potential for widespread use in the maritime education field.
