As we live in real If era, If become a mandatory component for nations and organizations to survive in severe competition. If is also thought of as strategic asset for effective business operations, yet there is no proved statement on the interoperability and system integration which causes serious problem in terms of requirement engineering among current systems. The National Defense Enterprise Architecture Framework is a strategic information asset base, which define the military operation activities for the mission, the information necessary for military operations, the technologies necessary for implementing new technology in response to changing operational needs. It is an integrated model or representation. Information Systems will be evolved by the National Defense Enterprise Architecture framework. The purpose of this framework is to present overall picture of national defense information system domain so that information systems are interoperated, integrated and information sharing is increased among affiliated organization of Defense Military.

Unmanned surface vehicles(USVs) have been developed for special operations in foreign navies. These will be employed to conduct critical missions including inspection, coast guard, ISR, fire protection, precision strike, mine interception warfare and antisubmarine warfare. It is also known the USVs will be deployed at the front line of the network-centric warfare to replace the manned naval operations. The unmanned operation can, thus, minimize unnecessary risk to personnel and enhance the success probability for the imposed mission. In this research, the USVs which are under operation and development in foreign navies are investigated. Based on this, an USV with $7\~10m$ of length and 10ton of weight for the Korean Navy which can be deployed near the Northern Limit Line(NLL), is proposed.

The Korean heliospheric community, led by the Korea Astronomy and Space Science Institute (KASI), is currently assessing the viability of deploying a spacecraft at the Sun-Earth Lagrange Point L4 in collaboration with National Aeronautics and Space Administration (NASA). The aim of this mission is to utilize a combination of remote sensing and in situ instruments for comprehensive observations, complementing the capabilities of the L1 and L5 observatories. The paper outlines longterm scientific objectives, underscoring the significance of multi-point in-situ observations to better understand critical heliospheric phenomena. These include coronal mass ejections, magnetic flux ropes, heliospheric current sheets, kinetic waves and instabilities, suprathermal electrons and solar energetic particle events, as well as remote detection of solar radiation phenomena. Furthermore, the mission's significance in advancing space weather prediction and space radiation exposure assessment models through the integration of L4 observations is discussed. This article is concluded with an emphasis on the potential of L4 observations to propel advancements in heliospheric science.

Thermal imager is now regarded as one of the key observation devices for ISR activities and getting important more and more. As other detectors, however, the thermal detectors also have maximum input and therefore they will be saturated if the input IR energy exceeds the allowed range. The saturation in the thermal detector makes it impossible to distinguish the target from background, as a result, the thermal imager does not perform its own mission anymore. In order to get an insight related with the image saturation, this paper develops a saturation model for a thermal imaging system, not a thermal detector. The proposed modeling starts from analyzing the specification of a thermal imager. Coupled with the characteristic parameters of the object, the saturation model can be used to predict the distance on which the detector is saturated. The proposed saturation model prove its validity by applying it for the case of observing a flash-bang.

To develop a high-resolution electro-optical/infrared (EO/IR) payload to be mounted on a high-speed and performance fighter aircraft in an external POD for acquiring daytime and nighttime image information on tactical targets, simulations, including flight environments and maneuvers, should be performed. Such simulations are pertinent to predicting the performance of several variables, such as aerodynamic force and inertia load acting on the payload. This paper describes the development of a flight data acquisition and analysis system based on flight simulation software (SW) for mission simulation of super-maneuverability fighter equipped with EO/IR payload. The effectiveness of the system is verified through comparison with actual flight data. The proposed flight data acquisition and analysis system based on FlightGear can be used as an M&S tool for system performance analysis in the development of the EO/IR payload.

Unmanned Aerial Vehicles (UAVs), which were used for military purposes, are gradually expanding their application fields under the influence of electrification and digitalization. Starting from the field of aerial imaging and Intelligence Surveillance and Reconnaissance (ISR) mission, nowadays the possibility of Urban Air Mobility (UAM), which transports passengers and cargo with drones, is widely under discussion. In order to occupy the rapidly growing global unmanned aerial vehicle market in advance, it is necessary to secure core technologies and develop key UAVs components based on the new technologies. In the navigation field, it is necessary to secure a precise position with guaranteed reliability and continuity, unrelated to the operating environments. The reliability and continuity should be secured in the algorithm level and in the H/W component levels also. In order to achieve this technical goal, the Ministry of Science and ICT has launched the 'Unmanned Vehicle Core Technology Research and Development Program' in 2019 to support the R&D on the unmanned vehicle technologies. In this paper, authors introduce the unmanned vehicle core technology research and development program to the related researchers. The authors summarize the backgrounds of the program and show the technological tasks and objectives on the sub-programs in the unmanned vehicle navigation program. We present the program schedules especially focused on the test and evaluation of the developed technologies and components.

시장 경제 자본주의 체제 하에서 부의 불평등, 재분배 기능의 한계, 자본의 흐름에 따른 비효율적 과대생산과 과대소비, 인간 존엄성과 자유의 제한 등의 한계점이 드러나고 있다. 이러한 한계를 조정하기 위하여 새로운 공생의 가치 마련이 요구되고 있으며, 개별 기업 단위에서도 사회적 책임과 공유가치에 대한 요구가 강조되고 있다. 기업의 사적 영리와 사회적 가치를 동시에 추구하고자 하는 사회적 경제 또는 사회적 기업의 형태가 사회공유 가치창출의 대안으로 제시되어, 그 가능성과 영역을 확대하고 있다. 기술적인 면에서 인터넷과 스마트폰을 비롯한 모바일 단말기의 급속한 보급은 대중 참여의 공유경제 확산을 가능하게 만들고 있다. 정보통신 플랫폼과 빅테이터 분석과 같은 초고속 네트워크 통신 및 대용량 데이터 처리 기술의 발달은 개인 대 개인, 기업 대 개인 간의 소통이 실시간으로 가능하게 함으로써 광범위한 수요자와 공급자를 연결해 주어 공유 시장을 확대함에 큰 역할을 하고 있다. 이 논문에서는 지역 협력적 소비를 바탕으로 정보통신기술(Information & Communication Technology)을 활용하여 자전거 관련 공유경제 시스템을 구축, 사회적 기업으로 창업한 (주)푸른바이크쉐어링의 사례를 살펴본다. 푸른바이크쉐어링은 공유, 공생, 공헌의 사회적 책임을 사업 모형 속에 접목하여, 지역 내의 다양한 협력 주체들과의 협업을 통한 사회적 기업을 운영하고 있다. 사례 분석을 통하여, 사회적 기업의 지속가능성을 추구하는 핵심적 요인으로 지역 사회 네트워크 활용이 가능하며, 사회적 기업과 공유경제의 융합 사업 모형을 통해 사회적 기업의 한계를 극복할 수 있는 대안이 될 수 있음을 검토하였다. 또한 정보통신기술의 발달에 따른 기술적 환경 변화가 어떻게 공유경제 시스템에 효과적으로 적용될 수 있는지를 보이고자 하였다. 선행적 이론 정리를 위하여, 사회적 기업의 개념과 현황, 기업의 사회적 책임에 대한 선행 연구의 내용을 살피고, 공유경제의 개념과 특징, 기업의 공유가치 확대에 대한 이론을 정리하였다.
