해상을 통해 반출입되는 항만 컨테이너는 선박과 항만에서의 안전사고를 예방하기 위해 국제해상위험물규칙의 규정을 준수하였는지 검사하고 컨테이너의 안전성을 점검한다. 하지만 지금까지의 컨테이너 및 위험화물의 검색은 대부분 사람에 의한 수동 운용으로 이루어지고 있어 향후 자율운항선박의 도래에 따른 자동화 항만을 위해서는 자동화된 검색 기술과 더불어 대상 컨테이너의 무인 자동화 검색이 가능하도록 운영이 될 필요가 있으며, 보다 진보적이고 효과적인 컨테이너 검색기술을 활용하기 위해 컨테이너 검색정보 표준을 개발하여 컨테이너 보안검색의 효율성 및 검색 활동에 대한 업무 비효율적인 문제를 해결하고자 한다.

Global discussions are actively underway regarding the introduction of urban air mobility (UAM) to revolutionize the paradigm in the innovative mobility industry. While research related to airspace, vertiports, navigation, and communication pertinent to Korean UAM is actively pursued by relevant research institutions, there is a significant dearth in studies focusing on establishing concepts for operational management by UAM operators and formulating control procedures. The commercialization of UAM necessitates the establishment of standardized operational management concepts, pivotal as benchmarks for the individual system development among multiple UAM operators. This paper analyzes UAM exceptional law, operational readiness, existing regulations pertaining to commercial and rotary-wing aircraft, and proposes suitable approaches to formulate domestic low-density operational management and control procedures. By presenting strategies for conceptualizing operational management and control procedures in the initial low-density environment for UAM, this paper aspires to contribute to future trail operations and the wider adoption of UAM.

Recently, vessel's average speed in the sea becomes fast because of the increasing of high-speeds vessel like a container ship and ferry. So, it is considered that speed control in the korean narrow waterway isn't the proper vessel traffic management, now. And, there is a rare paper studied about speed control quantitatively and numerically, especially speed control is discussing continuously, as abrogation of Incheon Port's speed control and alleviation of Kwangyang Port's speed control a according to navigating mariner's request. After this paper replayed the navigation traffic flow in the straight waterway using marine traffic flow simulation, the Environmental Stress Model is introduced to evaluate difficulty of each vessel's traffic.

Recently, ships' average navigation speed become faster than before because of the increasing of high-speeds vessel including container ships and passenger-ferries. So, it is considered that the speed limit in the navigation channel in Korea isn't proper for vessel management in these days. Also, there is rare paper studies about the speed limit quantitatively and numerically, especially the speed limit is discussing continuously, as abrogation of Incheon Port's speed limit and alleviation of Gwang-yang Port's speed limit according to the requests by the navigating mariners. Consequently this paper deals with the effectiveness of speed limits using the Environmental Stress Model, after replay of the navigation traffic flow in the straight waterway using marine traffic flow simulation technique.

This study is a pilot operation roadmap for the introduction of the co-pilot qualification (MPL) system, and the introduction of the MPL system in Korea is a new pilot education and qualification system based on competency. Therefore, it may be difficult to prepare for various matters such as securing initial regulations, securing training businesses or trainees, and establishing training infrastructure, so the roadmap necessary for pilot operation is very important for the successful introduction of the MPL system. In order to secure a training program and qualification system with proven MPL systems in the domestic aviation market, the government and aviation industry members will jointly participate to highlight the importance of a pilot operation roadmap for the domestic flight environment.

Our nation have several procedures and law for national airspace management, however those procedures and law not enough to manage airspace. Therefore, I have studied this paper for improving flight safety and for providing economics flight of civcil aircraft and military aircraft, also, for increasing efficiency of airspace through systematic airspace management, additionally, for improving nation defense ability and for preventation our nation damage when occuring airspace problem. Nowaday. in using airspace. two theory which freely use theory and use theory under jurisdiction is opposed by every nation in worldwide. Consequently. we can realize every nation endeavour to increase their jurisdiction airspace. However. our nation is not still prepared to cope with other nation when occuring airspace trouble. because airspace definition is not prescribed on our aviation law. Therefore. several problems which are improved in our airspace management are presented on this paper. The presented matters are as follows. First, The airspace definition is not prescribed on aviation law and responsibility limit of airspace management is ambugious. Second. problem on structure of approach control area and special airspace, Third. problem on airway system. Fourth. civil agency and military agency apply respectively different regulation in establishment of aircraft flight route, To grasp these problems, considered the airspace conception, airspace classfication. legal character of airspace. our nation airspace state and management together with other nation airspace state and management. also compared our nation airspace management with other nation airspace management. And. improvement methods to solve problems which was appeared by comparing and analysis are presented on this paper.

Ground, sea and air mobility, such as vehicles, ships, and airplanes, are generally operated by people. Based on the innovative development of autonomous decision-making systems and artificial intelligence (AI) following the recent fourth industrial revolution, research and development on maritime autonomous surface ships (MASS) is been actively performed around the world. Before the realization of the commercialization of MASS in international maritime transport, it is urgent to clarify the characteristics of this ship and its international legal status. This paper aims to analyze the concern of whether a ship without crew members will eventually be operated as a fully unmanned ship or can be recognized as a ship under international law as the number of crew members is gradually reduced owing to the development stage of autonomous ships. Consequently, based on the United Nations Convention on the Law of the Sea (UNCLOS) and the regulations of the International Maritime Organization (IMO), it was found that MASS has the same international legal status as general ships. In addition this paper presents the working principles of enacting and revising the IMO Conventions and international legal measures necessary for the safe operation of MASS.

At the design stage, it is very important to know the ship maneuvering characteristics from the view point of ship performance and for the safety of navigation. IMO only gives some criteria for ships in full load even keel condition. However, the ship generally is operated not only in full load condition but also in half load condition or ballast condition. Therefore we must estimate the ship maneuvering in different loading condition to ensure that the ship will satisfy with IMO rules and navigate safely in every condition. In this paper, we have investigated the maneuvering characteristics of a ship by simulation and experiments with real ship. By comparing with the results of simulation, the real ship tests conform with simulation test and previous researches. Therefore, the method base on real data is well done to estimate the ship maneuvering in different loading conditions. The change of ship's manoeuverability accoriding to ship's operation conditions was estimated.

This paper reviews and criticizes some issues as to the case of A and Others v. Finnair Oyj [2020] Case C-832/18 by examining EU Regulations and practical point of views. Under this case, the travellers brought an action against Finnair in light of the Air Passenger Regulation12, seeking compensation for both the first cancelled flight, and the delayed re-routed flight. Finnair had paid the first compensation, but refused to grant the second claim, arguing that the regulation did not set out that passengers were eligible for a second claim in those situations, and that the delay of the second flight was a consequence of 'extraordinary circumstances' under the regulation. The Court of Appeal in Helsinki has asked the CJEU whether an air passenger is entitled to a further compensation where a re-routed flight they have agreed to take is delayed, where both the original and rerouted flight are operated by the same air carrier. The CJEU held that the regulation does not in any way limit the rights of passengers where they find their flights being re-routed. As such, under earlier CJEU case law, the relevant travellers here were entitled to compensation for cancellation of the first flight and delay of the second flight. It also disagreed with Finnair's assessment that the technical failure in the re-routing flight was a matter of extraordinary circumstances.
