This paper presents the spillover effects for mobile long-range radar Research and Development(R&D) program to improve Intelligence, Surveillance and Reconnaissance(ISR) capability on the national economy. To evaluate the effects using inter-industry analysis, we estimate that the R&D cost of mobile long-range radar system is about 54.2 billion won, assuming the development period to be 5 years from 2017 to 2021. The analysis results show that the inducement effects for production, value added, and employment are 55.7 billion won, 16.6 billion won, and 171 people, respectively. This study provides the good example of how to evaluate the economic spillover effects of developing weapon systems domestically, showing importance and benefits of it.

Today, the 4th industrial revolution has become a major issue in all areas of the world, and the defense sector is no exception. In particular, the characteristics of the future battlefields will be further expanded through the main technologies that will lead the 4th industrial revolution. The CPS(Cyber-Physical System) will strengthen the network characteristics and the IoT(Internet of Things) will expand the information gathering ability. In addition, big data technology will contribute to providing quality information, and artificial intelligence will make the best judgment based on the information provided through big data analysis. Finally, the robot performs an operational mission on behalf of human beings. Robots are expected to affect the future weapon system more specifically. UAVs(Unmanned aerial vehicles) are already in the process of being deployed and newly developed. UCAV(Unmanned Combat Aerial Vehicle) is expected to be used in combination with manned aerial vehicle due to technical limitations, but UAV is expected to replace all existing aircraft. The rate at which the 4th industrial revolution affects our daily lives and national defense is different from that of the 1st, 2nd and 3rd industrial revolutions. Therefore, it is necessary to hasten the investment in research and development of the weapon system. In addition, we must hasten establishment of operational concept based on combined UAV and manned aerial vehicle operations. In the future, it will be necessary to prepare an air operations mission using only UAV.

Unlike terrestrial transportation, marine transportation should consider environment factors in order to optimize path planning. This is because, ship's path planning is greatly influenced by real-time ocean environment-sea currents, wave and wind. Therefore, in this study, we suggest a ship path planning algorithm based on real-time ocean environment using not only $A^*$ algorithm but also path smoothing method. Moreover, in order to improve objective function value, we also consider ship's moving distance based on ship's location and real-time ocean environment data on grid map. The efficiency of the suggested algorithm is proved by comparing with $A^*$ algorithm only. This algorithm can be used as a reasonable automatics control system algorithm for unmaned ship.

In the era of Big Blur, a significant number of emerging technologies, have promoted unexpected rapid changes in technological and social developments. However, with radical innovation and change, many potential users rarely estimate how to utilize emerging technologies and their applications. This study proposes a framework for evaluating potential users expectations of emerging technologies. To do this, we gathered various posts in online forums as new data. In addition, we defined and estimated the satisfaction and suitability of emerging technologies through several indices. Then, we evaluated the utilization of emerging technologies by constructing PROMETHEE model which could analyze two heterogeneous variables - satisfaction and suitability. These implications can be used as directions for applying emerging technologies that can bring high utility to potential users in the future.

With the development of modern science and technology, weapon systems such as tanks, submarines, combat planes, radar are also dramatically advanced. Among these weapon systems, the ballistic missile, one of the asymmetric forces, could be considered as a very economical means to attack the core facilities of the other country in order to achieve the strategic goals of the country during the war. Because of the current ballistic missile threat from the North Korea, establishing a missile defense (MD) system becomes one of the major national defense issues. This study focused on the optimization of air defense artillery units’ deployment for effective ballistic missile defense. To optimize the deployment of the units, firstly this study examined the possibility of defense, according to the presence of orbital coordinates of ballistic missiles in the limited defense range of air defense artillery units. This constraint on the defense range is originated from the characteristics of anti-ballistic missiles (ABMs) such as PATRIOT. Secondly, this study proposed the optimized mathematical model considering the total covering problem of binary integer program-ming, as an optimal deployment of air defense artillery units for defending every core defense facility with the least number of such units. Finally, numerical experiments were conducted to show how the suggested approach works. Assuming the current state of the Korean peninsula, the study arbitrarily set ballistic missile bases of the North Korea and core defense facilities of the South Korea. Under these conditions, numerical experiments were executed by utilizing MATLAB R2010a of the MathWorks, Inc.

북핵 위기 대응을 위한 특단의 방안 필요성에 관한 연구 - 북핵 개발에 대한 NPT· IAEA 기능의 한계점을 중심으로 -

There is a need for special measures to overcome the North Korean nuclear threat that has recently been advanced. This study aims to analyze the limitations of the NPT and IAEA's functions and roles in relation to the issue of North Korea's nuclear development, which is an absolute threat to the security situation on the Korean Peninsula and surrounding Northeast Asia, and to propose special measures to respond to the fundamental North Korean nuclear crisis. South Korea must be at the forefront of its role to prepare for the Korean Peninsula's crisis, which is still facing the threat of North Korea and the lack of deterrence against nuclear proliferation. Furthermore, it is of utmost importance to seek long-term and preemptive countermeasures and to ensure the understanding and tolerance of neighboring countries on the justification for realizing them. As a result of analyzing it in search of a special plan, effective sanctions by the NPT and IAEA against North Korea's nuclear development activities were extremely limited and only extremely passive, such as repeating simple normative resolutions. Therefore, in order to properly prescribe effective resolution of the North Korean nuclear threat, the application of nuclear non-proliferation regime regulations is required more strictly, and in case of violating this, severe international sanctions must be initiated. As a result, a clear and effective solution is required in the existing approach to resolving the North Korean nuclear issue. This study proposes the need for tactical nuclear redeployment or provisional self-development as a special way to respond to the North Korean nuclear crisis. It is impossible to permanently rely on multilateral or bilateral dialogue or negotiations, as well as the provision of nuclear umbrellas and extended deterrence measures between Korea and the United States, which have previously been ineffective. It is time to break away from the framework of the existing approach given the advanced North Korean nuclear capabilities. As a result, the North Korean nuclear crisis must be overcome as a fundamental and effective countermeasure, and international sanctions and economic damage are expected, but national existence and maintenance of the right to live are ultimately more important.

한반도에서 재래식 무기의 군비통제 방안 -운용적 군비통제 방안을 중심으로-

이장호 ( Lee Jangho ),설현주 ( Seol Hyeonju ) 미래군사학회 2024 한국군사학논총 Vol.13 No.1

This paper aims to explore operational arms control measures for conventional weapons on the Korean Peninsula. In the wake of the Cold War's end, the international community has intensified its focus and efforts on arms control, expanding its scope and objectives. However, the Korean Peninsula is witnessing a concerning trend towards arms buildup rather than arms control, necessitating urgent diagnosis and solutions. Currently, North Korea's political stance, including its public declaration of the Republic of Korea as its main enemy, raises doubts about the feasibility of political dialogue and trust-building. Additionally, asymmetries in threat perception and military capabilities between the two Koreas present challenges in applying a step-by-step arms control approach. Emphasizing the paramount importance of a comprehensive plan for maintaining denuclearization and security on the Korean Peninsula, this paper argues that arms control is not merely an option but an inevitable necessity. By analyzing the conditions for arms control of conventional weapons on the Korean Peninsula, this paper proposes operational arms control promotion plans centered on trust-building and relationship improvement, aligning with global arms control trends.
