Smart Security is the global initiative of Airports Council International in collaboration with airports, airlines and governmental agencies. Its main objective is to create a step change in passenger and cabin baggage screening, escalating security costs and constantly evolving threats. Incheon International Airport should adopt and deploy smart security systems not only to strengthen aviation security but also increase passenger's experiences and operational efficiency by way of seamless security screening that it will lead to establish the best security environment to prevent terrorism and acts of unlawful interference.

주변국들의 군사혁신 추세는 현존하는 북한의 위협과 함께 한반도 주변의 안보환경을 매우 불안정하게 하고 있다. 우리는 주변강국의 군사혁신 추세를 대칭적으로 따라잡기는 어려우므로, 작지만 정보화, 과학화, 정예화된 당찬 군사력을 확보하고자 우리의 현 능력을 최대한 활용하여 정보통신 및 전장관리체제, 해상.해중.항공전력별 무기체계 발전, 부대구조의 재편성 및 전력운영개념의 발전분야를 중심으로 지혜로운 군사혁신을 추진해야 할 것이다.

In this paper, the combat effectiveness of ship guidance rockets to counter the threat of multiple USV(Unmanned Surface Vehicle) was analyzed in three cases. The probability of sinking a number of USVs approaching by distance was compared using various weapon systems and guided rocket systems installed on the naval vessels. As a result of the analysis, it was found that the combat effectiveness of the guided rocket was improved compared to the close defense system of the anti-ship missile installed on the naval vessels.

The penalty clauses of 'Aviation Act' and 'Aviation Safety and Security Act' going into effect now were legislated because the aviation safety is being more influenced by the aviation safety system compared to the ground or maritime transportation and it is possible the aircraft can harm to people and wealth located in the ground as well as threaten the safety of the passengers and crew on board when it is the target of crimes. However, analyzing the current acts, applicable objects and behavioral requirements of some provisions are too general, and they are providing severely high penalties in many clauses without separating applicable objects and behavioral requirements. In addition, there are some critical legislative defects and there is a problem in terms of law-applicable area in the legal system. It is inferred that these legislative problems of the criminal special-law related to the aviation were caused by following reasons; first, aviation security experts or policy-makers than criminal law experts attended more actively in the enactment process, second, the communication among specialist groups were not accomplished well enough.

외부이물질에 의한 손상(FOD)으로 인해 항공기 및 엔진 등의 원상복구를 위한 비용손실 뿐만 아니라 항공기 안전운항에 큰 위협요인으로 부각되고 있다. 그러나 우리나라 FOD와 관련 된 연구 실태는 엔진부품, 타이어, 기체 및 조류충돌에 의한 사건사고에 대한 통계분석 등이 주를 이루고 있으며, 잠재적으로 FOD를 유발할 수 있는 항공기를 정비하고 취급하는 정비사 및 지상 조업직원 등의 인적요인을 고려한 연구는 전무한 실정이다. 이에 본 연구에서는 FOD의 정의와 발생 원인들을 살펴보고, 항공정비사를 비롯한 지상 조업직원들의 인적요인에 의한 FOD 유발가능성 등을 연구하여 FOD방지를 위한 개선 방안을 제시하고자 한다.

전 세계적으로 미세먼지는 심각한 사회문제이다. 우리나라 또한 중국의 미세먼지와 디젤 자동차 급증 등에 의한 오염으로 인하여 호흡 시 들이마시는 공기의 질이 많이 나빠지고 있는 추세이다. 이로 인해 집 안의 환기를 위해 창문을 열거나 외출 후 귀가했을 때 옷에 붙은 미세먼지들에 의하여 집 안에 미세먼지가 쌓이게 됨으로써 건강을 위협할 수 있는 요소가 된다. 이러한 문제점들을 해결하고자 청소뿐만 아니라 공기청정 기능도 수행하게 되는 효율적인 측면을 가진 공기청정 기능을 탑재한 로봇청소기를 개발하였다. 따라서 본 논문에서는 로봇청소기의 초음파 센서와 미세먼지를 사용하여 자동으로 로봇청소기와 공기청정 기능을 탑재한 로봇청소기에 대한 연구 결과에 관해 기술하였다.

In order to provide precision approach service based on GBAS, air navigation service providers should validate the GBAS system performance against international standard requirements and receive approval. The GBAS manufacturer should define integrity threat, analyze the integrity monitors and evaluate performance of the implemented monitors to verify integrity performance which is critical to the aircraft safety. This paper describes a statistical test result to evaluate performance of the code carrier divergence monitors implemented in KARI Integrity Monitor System software. The paper introduces analysis and test procedure which is developed for the performance evaluation and describes the analysis, the test scenario generation and the test results. The results show that the implemented monitors can detect the expected minimum detectable errors with satisfying the probability of missed detection requirements.

The weapon-target assignment (WTA) problem is a matter of effectively allocating weapons to a number of threats. The WTA in a rapidly changing dynamic environment of engagement must take into account both of properties of the threat and the weapon and the effect of the previous decision. We propose a method of applying the Greedy Randomized Adaptive Search Procedure (GRASP) algorithm, a kind of meta-heuristic method, to derive optimal solution for a dynamic WTA problem. Firstly, we define a dynamic WTA problem and formulate a mathematical model for applying the algorithm. For the purpose of the assignment strategy, the objective function is defined and time-varying constraints are considered. The dynamic WTA problem is then solved by applying the GRASP algorithm. The optimal solution characteristics of the formalized dynamic WTA problem are analyzed through the simulation, and the algorithm performance is verified via the Monte-Carlo simulation.

The airline industry has been growing steadily since 2016 with more than 100 million air passengers, renewing the largest number of air passengers every year. Increasing air demand leads to an increase in air traffic in limited airspace, increasing the likelihood of accidents between aircraft. Due to the massive human and material damage caused by a single mistake, aviation safety is being heavily focused around the world to efficiently use limited airspace. Studies related to various human factors are underway as most of the aviation accidents are found to be caused by human factors, but research on human factors by controllers is insufficient while they are active in terms of control and operation. Given that 82% of air accidents caused by controllers are caused by human error, the importance of management of human error and changes in perception are urgently needed. This study aims to understand the seriousness of the controller's human error by analyzing the accident cases caused by the controller's human error using TEM to identify threats and errors and derive common human factors.

While the numbers of overseas travelers has been increased rapidly each year, the numbers of passengers in the aircraft also has continued to be increased gradually. In the mist of these increasing numbers, such accidents as threatening an aircraft safety like riot, aircraft hijacking and terrorism have happened constantly. In these circumstances, South Korean government has prescribed "Aviation on Security Act" in accordance with the Convention on International Civil Aviation and other international agreements. This act aims to prevent illegal activities and illegal items on the aircraft to ensure the safety and security of civil aviation. However, this act is not sufficiently regulating all the illegal crimes and illegal items on the flight. For the worse, there is a lack of effective supervisory capacity. Likewise, the inherent problems of the current laws relating to the prevention of the illegal items on the aircraft are appearing on the surface continually. Above all, illegal items on the aircraft are directly connected to the issue of aviation safety and security as well as a safe utilization of the flight service. Thus, when there occurs a serious accident on board, it surely would be led to a huge economic loss not mentioning the loss of lives following the accident. Therefore safety of the flight passengers cannot be guaranteed without ensuring the safety of aircraft facilities and good supervisory mechanism of illegal items on the aircraft. Accordingly, establishing a safe operation order tends to influence economy and tourism of a country in no small measure. Therefore, it is an urgent issue to settle down a reasonable and adequate supervisory regulations regarding the prevention of the illegal items on the aircraft. Consequently, in this article, I studied on a reasonal and effective mechanism to control the prevention of the illegal items and illegal acts on the aircraft in order to ensure a safety and security of civil aircraft.
