The Army tried to settle the mission command in army command system in 1999 but still not be settled. One of the reason is the absence of practical plans of mission command. The purpose of this study is to find out the moderating effects of personal thinking type to the impact on organizational effectiveness about the impact on organizational effectiveness on sub factors the transformational leadership The main results of this study are as follows. <H1> The charisma and the personal considerations of sub factors of transformational leadership effected positively(+) on the job satisfaction, the charisma effected positively(+) on the organizational commitment. But There was no statistically significant influence on the personal considerations and the effort advocacy <H2> In the result of the moderating effects, in accordance the of a person's each cognitive processing traits is high and low, on the transformational leadership turned out to be a gap in the influence show the difference in organizational effectiveness.on the organizational effectiveness. This results suggest the following. The first. The military group regard highly commandand and discipline. so, the charisma of a superior is that a big impact on organizational effectiveness. The second, For the mission command is to become established in the army, It suggest that need to explore of sub factors of the mission command and need to consider of personal traits with the mission command.

Air Defense Command Control and Alert(ADC2A) system is a system that ensures simultaneity and integrity of air defense operations by combining sensors, weapons and Command and Control(C2) systems over a tactical network to protect forces, facilities and strategic points from enemy's air attack. Improving message processing speed is a very important factor for ADC2A, because it uses high frequency bit-processing of the Army standard KVMF message to communicate with internal and external systems. In this paper we proposed improved method of KVMF message processing for ADC2A system.

The army developed the ATCIS(Army Tactical Command Information System) for the battlefield information system with share the command control information through the realtime. The using the public key and the encryption equipment in the ATCIS is enough to the confidentiality, integrity. but, it is vulnerable about the availability with the zero day attack. In this paper, we implement the worm propagation simulation on the ATCIS infrastructure through the modelling on the ATCIS operation environment. We propose the countermeasures based on the results from the simulation.

In this paper, a command and control (C2) system development using a network emulator is treated. Due to the development of information and communication technologies enabling reinforcement of information exchange and computational capability, an operational concept network centric warfare (NCW) was introduced. In here, it summarizes a developmental test environment build based on dummynet, one of the software based network emulator, and an operational concept of target command and control system. Moreover, I explain command and control system developmental test cases and results, and suggest an operational concept to overcome limitations of target communication system. I expect this concept will reduce data traffic of proposed C2 system especially plot messages which is distributed same data with short interval.

In this paper, we considered the authoritative representation of Command and Fire Control System(CFCS) for the surface ship that was the engineering level model to develop system specifications and to analyze operational concepts on the concept design phase and to analyze military requirements, effectiveness and performance for the system. The engineering level model of CFCS can be used in simulation independently of the surface ship's type, and also it takes reuse, interoperability, and extension into consideration. The detailed sub-models, internal and external data interface, data flow among each sub-model, sensor and weapon models about the engineering level model of CFCS was defined. It was verified via engineering level simulations according to the V&V process.

첨단과학의 발달과 정보화 시대는 전쟁수행 패러다임을 근본적으로 변화시키고 있다. 이러한 전장 환경의 변화와 더불어 군 내부에서도 정보기술의 급격한 변화를 적극적으로 수용하고 21세기 국방을 건설하기 위한 국방 정보화 목표를 앞당기기 위해 수많은 정보기술체계를 도입하고 적용하고 있다. 이러한 수많은 체계들의 유입 속에서 각 체계간의 상관관계를 규명하여 효과적으로 사용하는 것은 중요한 문제로 대두되고 있으며, 이러한 문제의 해결방법으로 최근에 대두되고 있는 방법론이 사회연결망 분석(SNA : Social Network Analysis)이다. 사회연결만 분석은 무수히 많은 정보의 홍수 속에서 그들의 관계를 파악하고, 임무수행에 필요한 중요 노드를 식별하여 불필요한 자원을 낭비 하지 않은 중요한 요소를 분석 할 수 있는 유용한 방법론으로 사회, 문화 전반에 걸쳐 활발히 연구되고 있다. 본 논문에서는 이러한 사회연결망분석을 통해 지휘통제체계와 연계된 노드간의 관계를 규명하고, 관계망속에 속한 정보의 획득 및 흐름을 파악하여 이를 시각화하고자 한다. 이를 통해 현재 운용중인 지휘통제체계 구조에 대해 이해하기 쉽고, 용이하게 파악 할 수 있으며, 이를 기반으로 지휘구조의 조직과 조직적인 행동과 현상을 도출하고, 향후 군 네트워크 파워를 측정 할 수 있다.

Naval command and control system are very important for operation and their failures can be fatal for warfare. To prepare for these failures, we use feature selection method which is one of the data mining techniques. First, we analyzes failure data set of Navy from 2016 to 2018. And then We derive attributes that are associated with failure and to predict failure using feature selection method. We propose a method for prioritizing maintenance using the degree of association of attributes. This improves the efficiency and economics of command and control system maintenance.

Command and control (C2) information is exploding as sensor and network technologies development. In the C2 are a, processing information on time is very important. If it is not possible to process all information on time because of resource limitation, higher priority information should be processed first. For this, recommendation system is available. Because it can select and present information suitable for each user among tons of information in the order of priority. This study extends the triple-metric priority criterion, which is widely used to implement military communication networks, to the quadruple-metric priority criterion, and proposes a C2 information recommendation system based on it, and shows it's feasibility through experiments.

Purpose: This study identifies the impact on composition of the firefighting organization, fire command ability, and public opinion operation on organizational citizenship behavior for fire officials to respond to the earthquake disaster, and provides practical implications as basic data for firefighting organizations to cope with the earthquake disaster. Method: Questionnaire survey was performed for 159 fire officials, and the surveyed data was statistically analyzed by using SPSS 22.0 program. Result: First, the results of the verification of the hypothesis showed that the composition of the fire organization, firefield command ability and public opinion operation have a positive impact on organizational citizenship behavior. Second, the relative contribution of independent variables to the dependent variables was identified in the order of composition of fire organization, fire command ability and public opinion operation. Conclusion: The implications of this study suggested from a practical perspective that the government needs to organize firefighting organizations, develop firefield command ability and operate public opinion in advance in order to respond to earthquakes.

Due to its self-configuring nature, the tactical mobile ad hoc network is used for communications between tactical units and the command and control center (CCC) in battlefields, where communication infrastructure is not available. However, when a tactical unit moves far away from the CCC or there are geographical constraints, the data link between two communicating nodes can be broken, which results in an invalid data route from the tactical units to CCC. In order to address this problem, in this paper we propose a hierarchical connectivity maintenance scheme, namely ADLCoM (Autonomous Data Link Connectivity Maintenance). In ADLCoM, each tactical unit has one or more GW (gateway), which checks the status of data links between tactical units. If there is a possibility of link breakage, GWs request ground or aerial unmanned vehicles to become a relay for the data link. The simulation results, based on tactical scenarios, show that the proposed scheme can significantly improve the network performance with respect to data delivery ratio.
