The artificial intelligence (AI) is a technology that will lead the future connective and intelligent era by combining with almost all industries in manufacturing and service industry. Although Korea is one of the world's leading artificial intelligence group with the United States, Japan, and Germany, but its competitiveness in terms of artificial intelligence patent is relatively low compared to others. Therefore, it is necessary to carry out quantitative analysis of artificial intelligence patents in various aspects in order to examine national competitiveness, major industries and future development directions in artificial intelligence technology. In this study, we use the IPC technology classification code to estimate the overall life cycle and the speed of development of the artificial intelligence technology. We collected patents related to artificial intelligence from 2008 to 2018, and analyze patent trends through one-dimensional statistical analysis, two-dimensional statistical analysis and network analysis. We expect that the technological trends of the artificial intelligence industry discovered from this study will be exploited to the strategies of the artificial intelligence technology and the policy making of the government.

The warfare caused a dramatic change when new technology was introduced to the battlefield or when the technology was matured to change the concept of operation. Thus, the rapid development of science since the 19th century is also rapidly changing the aspect and speed of war, and the recent speed of change is making it more difficult to predict future warfare than in the past In particular, in the past, it was difficult to predict the future warfare based on the latest science and technology, because it was difficult to spread and seize advanced science and technology. But global human exchange, technology hijacking by internet, and developing of asymmetric skills and methods caused more complex to technology based warfare prediction. In other words, the nature and principles of war, together with the development of science and technology, should be considered togther to predict future warfare. Therefore this study is based on the thory and principles of war and the latest science and technology to predict the future warfare situation that the military will face.

Newly, the fourth industrial revolution is a way of describing the blurring of boundaries between the physical, digital, and biological worlds. It's a fusion of advances in AI (artificial intelligence), robotics, the IoT (Internet of Things), 3d printing, genetic engineering, quantum computing, and other technologies. At the world economic forum in Davos, switzerland, in january 2016, chairman professor klaus schwab proposed the fourth industrial revolution for the first time. In order to apply the AHP (analytic hierarchy process) analysis method, the first stage factors were designed as Natural, Water, Earth and Atom energy. In addition, the second stage factors were organized into 9 detailed energies presented in the conceptual model. Thus, we present the theoretical and practical implications of these results.

In the hyper-connected network, which network equipment is diverse and network structure is complex, the attack surface has also increased. In this environment, MTD(Moving Target Defense) technology is being researched as a method to fundamentally defend against cyber attacks by actively changing the attack surface. network-based MTD technologies are being widely studied. However, in order for network address mutation technology to be applied within the existing fixed IP-based system, research is needed to determine what impact it will have. In this paper, we studied the impact of applying network address mutation technology to the existing network protection system. As a result of the study, factors to be considered when firewall, NAC, IPS, and network address mutation technologies are operated together were derived, and elements that must be managed in network address mutation technology for interoperability with the network analysis system were suggested.

Development of 5th generation mobile telecommunication technology is visualizing ideal hyper-connected social information and communication technology (ICT). In particular, virtual reality (VR) technology is at the starting point for new expansion and leaps. This work defines virtual reality as media in this context and collects and analyzes discourse on its scalability around space and communication theory. We first elaborated the concept, starting with the early discussions of the virtual reality concept in 1990, and discussed the relationship between the physical world and digital information, expression and interaction immersion as a medium, simulation, art creation theory, and finally evolutionary development. In conclusion, beyond the discourse on the technology of virtual reality, academic subjects were required to have theoretical frameworks on cognitive science, neuroscience, social science, and humanities issues (ethics, personality, etc.) for the development and evolution of virtual reality. In other words, it is time for the evolution of virtual reality to be discussed, which can be moved beyond.

최근 모든 분야의 산업 발전에 있어 AI의 중요성은 증가하고 있다. 초연결성, 초지능성을 특징으로 하는 정보산업의 혁명인 4차 산업혁명은 핵심 기술인 AI가 견인하고 있기 때문이다. AI 산업의 시장규모는 기하급수적으로 성장할 것이라는 전망이 나오는 반면, 성장률의 둔화 추세와 이런 결과를 뒷받침하는 우려 사항들도 제기되고 있다. 특히, AI의 판단에 대한 신뢰는 AI의 활용을 위해 확보해야 하는 주요 과제로 인식되고 있다. 본 고에서는 방송·미디어에서도 AI에 대한 신뢰가 왜 중요한지, 그리고 이를 확보하기 위해 해외에서 어떤 활동들을 하고 있는지 특히 유럽의 동향을 위주로 소개하고자 한다. 또한, 사람들이 대부분의 생활 정보를 얻는 방송·미디어에서 신뢰할 수 있는 AI를 활용하기 위한 방송사의 역할에 대해 알아보고자 한다.

The study presents milestones for the Korean military to win the future battlefield based on the 4th Industrial Revolution. Chapter 1 deals with the necessity of research on how advanced countries operate industrial technology in the defense sector based on the 4th Industrial Revolution. Chapter 2 examines the current technology status of the 4th Industrial Revolution in Korea and the concept of Korean combat. Chapter 3 analyzes the military robotic technology of advanced military countries through examples of unmanned combat robots in the United States, Israel, and Germany. In the end, in future battles, it will be possible to dominate the battlefield only by taking a leap into a super-connected and super-intelligent military based on a high-tech platform. Our military should also research and develop military robotics in accordance with the characteristics of each combat system, and further expand and develop the concept of combat performance to protect our core capabilities and centers from enemy cyber, electronic warfare, and space attacks.

The ROK Army is promoting cutting-edge, future-oriented military development such as a mobile, intelligent, and hyper-connected Army TIGER system. The future infantry brigade plans to increase mobility with squad-level tactical vehicles to enable combat in multi-domain operations and to deploy various weapon systems such as surveillance and reconnaissance drones. In addition, it will be developed into an intelligent unit that transmits and receives data collected through the weapon system through a hyper-connected network. Accordingly, the future infantry brigade will transmit and receive more data. However, the Army's tactical information communication system has limitations in operating as a tactical communication system for future units, such as low transmission speed and bandwidth and restrictions on communication support. Therefore, in this paper, the information distribution capability of the future infantry brigade is presented through the offensive operation scenario and M&S.

The fourth industrial revolution can be called the hyper-connected-based intelligent revolution triggered by advanced information technology and intelligent technology, and the basis for implementing these technologies is 'data'. This study proposes a way to strategically use data in order to lead this intelligent revolution in the defense area. First of all, implications through analysis of domestic and international trends and prior research and current status of defense data management were analyzed, and four directions for development were presented. If the government composes conditions for building, releasing, sharing, distribution, and convergence of defense data considering the environment of national defense in the future, it is expected that it will serve as a foundation and a shortcut to be a digitalized strong military through smart defense innovation in the era of the fourth industrial revolution.
