Soldiers management is the core of military combat power to preserve and accident prevention. But in unforeseen times and places did the unthinkable soldier causes an accident, the inexperienced primary officer were upset, and can often be quite nervous. And various accidents prevention is also win the war, the reason for existence in the military for combat readiness as a precondition for perfection. There are primary officers at the forefront of this critical mission. However, in spite of the lack of time to work for combat readiness, orders from higher units of troops management and that's level giving a lot of pressure to primary officer. So I made the primary officer military counseling model ike this. Using Primary officer counseling model is possible to rapid and efficient counseling advice against the target client soldier. The efficient counseling is must take precedence on understanding on client soldier deeply. Depth understanding someone needs a lot of effort and time. However, to Primary officer, it is true that they have a lack of condition that are enough to give the time and effort. Therefore, effective counseling and accident prevention is possible to use counseling model through choice and concentration activities.

The North's short-range projectiles and missiles are the Iskander-class missiles of the S-300 series, with a range of 270-420 kilometers and an altitude of 40-50 kilometers, making it very difficult to respond with South Korea's detection radar or striking weapons. The North's handling of the Seoul sea of fire also makes it very urgent for the South to deploy the weapons to power or introduce them as soon as possible, as it can identify its intention to strike the Seoul metropolitan area by equipping such short-range rockets and missiles with nuclear or chemical weapons. We will be prepared to prep are for reckless provocations by securing our own technology by continuously developing the Korean missile defense system and striking system, Kill Chain, which is designed to defend short-range missiles in the long-term, and securing our own technology.

Cyber space is a place where free activities are guaranteed. However, it is also true that not all individuals and countries strive for peaceful cyberspace, and that there is a growing tendency to gain unfair advantage through this space. Therefore, the state should reform laws and institutions to keep cyberspace safe. By establishing the "Basic Law on Cyberspace" which includes the law of the state law on cyberspace, it is necessary to be able to recognize and respond to the direction of the national legal discipline on cyberspace. The development of digital forensics is an urgent task due to the rapid development of IT. However, if the law is delayed for various reasons, some of the existing laws should be amended to improve the stability of the law in accordance with the circumstances. To this end, it is necessary to revise the "Information and Communication Infrastructure Protection Act", "Information and Communication Network Enhancement and Information Protection Act", "Integrated Defense Law", "Establishment of Defense Information Infrastructure Infrastructure and Defense Information Resource Management Act".

In this day and age physical and cyber boundaries have converged due to the development of new technologies, such as the Internet of Things (IoT) and the Cyber Physical System (CPS). As the relationship between physical system and cyber technology strengthens, more diverse and complex forms of risk emerge. As a result, it is becoming difficult for single organization or government to fully handle this situation alone and cooperation based on information sharing and the strengthening of active defense systems are needed. Shifting to a system in which information suitable for various entities can be shared and automatically responded to is also necessary. Therefore, this study tries to find improvements for the current system of threat information collecting and sharing that can actively and practically maintain cyber defense posture, focusing particularly on the structuring of information sharing platforms. To achieve our objective, we use a risk communication theory from the safety field and propose a new platform by combining an action-oriented security process model.

Recently, as weapon systems have become more complex and multi-functional, the difficulty of the operation and maintenance of weapon systems in the military have become increasingly difficult. On the other hand, the service period of operations and maintenance workers who perform operations and maintenance has been shortened, and the skill of system operation and maintenance has been lowered. This complexity and multi-functionality of equipment cause malfunctions and errors of users and maintenance personnel, and degradation of the reliability affects availability and combat readiness. In addition, life cycle costs have been gradually increasing. Therefore, I would like to suggest an improvement plan of the design of weapon systems and ILS (Integrated Logistics Support) in order to examine the implications of failure in the military. The weapon system is operated in the ROK Navy. Data from 730 cases of failure of weapon systems was collected, and analyzed. The results of the analysis are classified into failures that can be prevented in advance and failures that cannot be prevented. This shows the portion of preventable failures in weapon systems and proposes measures to minimize failures.

The standardization of weapon system parts is one of the elements of parts management and is an important factor for reducing the cost of acquiring and maintaining a weapon system, enhancing its reliability, improving interoperability, alleviating parts obsolescence problems, improving logistics efficiency, and strengthening the military's combat readiness. This study examined how to manage parts of domestic R&D weapon systems, overseas imports weapon system parts, and various commercial parts from a standardization perspective, and to study parts management methods for standardizing parts in the future. This system was used to achieve systematic part standardization in a military weapon system. To this end, this study investigated what elements are used to standardize weapon system parts. The importance and weight of each element were calculated using the AHP (Analytic Hierarchy Process), one of the decision-making techniques, and the design stage standards using the part selection method were studied. Through this, the selection process of standard parts, which has been made according to the experience and subjective judgment of designers and personnel, was improved to propose a systematic and objective method of standardizing weapons parts.

According to the 「Child Welfare Act, Article 16(1)」, when the age of a child reaches 18, he or she is discharged from prison. However, in order to prepare an effective support posture from the central government and local governments, a clear fact-finding survey on children who have completed protection is necessary. Therefore, in this study, the most basic questionnaire on housing, health, education, employment, and social relations of children living in Cheonan City after completion of protection is required. An investigation was conducted. As a result, the housing and social relationship of children living in Cheonan city were good compared to children living in Cheonan city compared to children who completed protection nationwide. Therefore, it was found that it is urgent to establish a close cooperation system with related organizations in this regard.

This paper addresses the berth allocation problem in naval ports. Navy vessels need various services such as emergency repair, missile loading, oil supply and many others while commercial vessels only unload and load container at the port. Furthermore, naval vessels have to shift frequently due to a limited capacity of the port. The objective of this paper is to minimize the total number of nesting vessels at the naval port. In other word, the objective is to maximize the total number of naval battleships engaging in the sea. A mixed integer programming(MIP) model is developed and experiments are conducted with ILOG CPLEX 11.0. We compare the computational results of the MIP model to the current scheduling approach by the ROK Navy. The results showed that MIP model performed well by minimizing the number of nesting vessels. and avoiding unnecessary shifts.

Recent aggressive threats by North Korea using small drones have heavily impacted on ROK(Republic of Korea) society and it seems to be agreed that counter-drone systems are required to protect our properties. ROK government has been investigating current counter-drone systems for national important facilities. However, there is no consensus standard to evaluate the systems. This paper is to propose a counter-drone system evaluation framework which is the outcome through RMA(Revolution in Military Affairs) thinking process. The RMA thinking process is currently well-implemented in ROK army to develop future military strategy. The proposed framework has 4 categories - threat analysis of North Korea small drones, convergence of detection, tracking and neutralizing systems, integrated operations and available experts and organization - which have corresponding criteria.
