As weapons systems are fused with advanced technologies, many of the expenses for research and development are favorites, and that group demands high reliability of weapons systems before the lifecycle. However, empirical studies on the reliability of defense weapons systems are restricted to lack of attention and limitation of data. In this research, we proposed the process of collecting field operation specifications based on the experience gathered by visiting directly to the weapons system operator's trap, strategy and maintenance support force (COMROKFLT, Naval Logistics Command, Naval Shipyard, production company). We used this to derive the operation MTBF of the solubility inducing bullet shooting system and compared it with the target value at the time of development.

This paper describes a development of the operational architecture of a low altitude air defense automation system using a systems engineering approach. The future battlefield is changing to new system of systems that command and control by the network based BM/C4I. Also, it is composed of various sensors and shooters in an single theater. Future threats may be characterized as unmanned mewing bodies that the strategic effect is great such as UAVs, cruise missiles or tactical ballistic missiles. New threats such as low altitude stealth cruise missiles may also appear. The implementation of a low altitude air defense against these future threats is required to complex and integrated approach based on systems engineering. In this view, this work established an operational scenario and derived operational requirements by identifying mission and future operational environments. It is presented the operational architecture of the low altitude air defense automation system by using the CORE 5.0.

As digital environment rapidly changes, various identification infrastructures have been introduced. It inevitably caused the Interoperability issue between the identifiers. Especially, Interoperability issue between the same kinds of identifiers raised the problems such as decreasing usefulness and cost overhead for making bridge system. In this paper, we resolve this issue by suggesting ID mashup service based on XRI. Although both UCI and ICN are the dominant identification infrastructures in the soundsource domain, the modification of identifiers or the requirement of complex system are essential for Interoperability. The ID mashup service suggested in the paper is able to provide interoperable functions to outer world without modifying the structures and resolution service of both identification infrastructures.

본 논문은 현재 국방 체계의 상호운용성 수준을 평가하는 방법으로 사용하는 LISI 모델에 대해 개선되어야 할 내용을 제시한다. 우리 군은 국방 체계에 대해 상호운용성 수준 측정을 위해 LISI를 기반으로 한 자동화 도구를 활용하는 등 상호운용성 확보를 위해 많은 노력을 기울이고 있다. 그러나 소요제기/개념단계, 설계 단계에서 적용되는 LISI 모델에는 미흡한 점이 있다. 이를 극복하기 위해 본 논문에서는 아키텍처 구축 시 LISI를 적용하는 방법에 대해 제안한다. 상호운용성이 확보 가능한 아키텍처를 구축하기 위해 서는 LISI를 기반으로 아키텍처 대안들을 평가함으로써 향후 개발에 적용될 아키텍처가 상호운용성 요구를 달성하고 있음을 검증해야 한다. 더불어 본 논문은 LISI 모델 기반 상호운용성 평가를 위해 주요하게 고려되는 능력모델에 대한 절차(P), 응용(A), 기반구조(I), 데이터(D) 내용을 참조모델을 통해 최신화하는 방안에 대해 제안한다.

With the advent of industry 4.0 technologies like the artificial intelligence and the autonomous flight, 'Urban Air Mobility (UAM)' is being considered as an effective alternative to resolve the ground urban traffic congestion. Accordingly, many companies in the world including Korea are investigating on the development of UAM vehicles and operation systems. In this study, after identifying and classifying the essential elements of the UAM operation, the UAM system operational concept has been derived, then detailed analyses for each element has been performed. Based on the conceptual analysis of the UAM operation system, UAM flight routes in Seoul and Gyeong-In area have been established and confirmed to be operable through the performance analysis of UAM vehicles. The flight route analysis in this study is expected to be applied to UAM flight routes establishment in various cities in the future.

In this research, we propose the operational method of the RFID-based NPI (National Product Identifier) which can manage product assets for the Korean government in the future. First of all, we present the operational concept of the national product asset management. Second, we suggest the structure of the NPI which accommodates ISO/IEC 15459 and the method to encode NPI and related data to ISO/IEC 18000-6C tags. Finally, we propose the operational business processes to generate and manage NPI in the stages of product procurement and product asset management.

Unmanned aerial vehicles(UAVs) operating in the military for various purposes are designed to transmit information collected according to the purpose to GCS(Ground Control System), and to transmit/receive the vehicle's operational control and status information using wireless communication(or datalink). Currently, the military UAV systems in operation in Korea use unique communication methods, protocols, and message structures for each system. In this paper, we analyze the TM/TC data protocol of two types of military UAV systems currently under development and propose a more efficient TM/TC message design scheme in wireless communication(or datalink) environment. And we will discuss issues to be considered for standardization of technology for ensuring interoperability with many UAVs or newly introduced UAV systems.

자율운항선박은 제4차 산업혁명 시대의 핵심기술인 사물인터넷과 빅데이터, 인공지능 등이 집약된 미래 고부가가치 선박으로 주목받고 있는 반면, 실제 선박 운항 중 많은 위험요소들로 선박 안전상의 우려가 제기되고 있다. 해양교통에 있어 안전규제는 해사안전 증진 및 해양사고 위험성을 최소화하기 위한 중요요소라고 할 수 있으며, 자율운항선박 시대에서도 동일하게 작용할 것으로 보인다. 이에 자율운항선박 시대 준비를 위한 안전규제의 재정립은 선박의 안전운항을 위한 안전관리체계 정비를 위한 핵심사항이라고 할 수 있으며. 최근 국내·외에서 논의되고 있는 자율운항선박 운항을 위한 규제 개발 역시 중요한 의미를 가진다. 본 논문에서는 자율운항선박 운용을 위한 안전규제체계 개선을 위해 실제 상용화를 앞둔 자율주행자동차 안전위험 이슈 분석 사례를 기반으로 자율운항선박 운용에 따른 안전위험 이슈를 도출했다. 이러한 결과는 자율운항선박의 운용을 위한 규제 개발 논의 시점에서 향후 자율운항선박의 상용화 및 안전규제체계 마련을 위한 기초자료로 활용 할 수 있을 것으로 기대된다.
