As the trend of future war has been changed to network centric warfare, tactical data link should be needed for fast and accurate situation awareness. Nowadays, Korean air force conducts military operations by using aircrafts equipped with Link-16. The Link-16 can conduct multiple mission at the same time because it supports multi-net capability. Due to lack of frequency resource, the way to share the frequency with other systems has been studied and using L band with radar is considered as one of the candidates bands. However, the data link can be affected by the interference from radars when it shares the L-band because the L-band in Korea is already assigned to long-range detection radars. In this paper, we evaluate operational possibilities of tactical data link in the L-band based on Link-16.

Be expressed in network-centric warfare, mainly battlefield environment of the future. The purpose of the system for the war of the future, is to recognize the enemy before the enemy, and rapid decision-making, to hit accurately. For this reason, it is during the construction of the integrated system of C4ISR+PGM. In such an integrated system, it is necessary to further enhance the security aspects of the information. In particular, strengthening of security leads to a decrease of efficiency. Therefore, security and efficiency should be considered together. In this study, we provide a homomorphic encryption system that can be safely managed information environment on the battlefield of the future. The proposed method uses encryption technology of homomorphic that can be the arithmetic operations on encrypted state. It has changed from the state of the encryption. Therefore, the attacker can not know a decent information.

In Network Centric Warfare (NCW) environment, having a tactical communication network which provides high data exchange rate is very important. In the process, Korean Army developed Mobile Subscriber Access Point (MSAP) which is based on the commercial Wireless BroadBand (Wibro). MSAP is a vehicle attached base station which provide high data exchange communication environment in a given area. Thus MSAP can provide high data exchange rate and mobility to accomplish missions in the battlefield more effectively. In this paper, we propose an operational strategy of using MSAP to provide tactical communication network in the battlefield. The idea is to find the optimal location point of the MSAP in the operational area where all the troops in the operational area can be supported by the MSAP with a minimum number of MSAP. Since the current Korean Army's basic idea of using MSAP is just distribute this MSAP to each troop, so by applying our strategy we can save MSAP devices for more flexible operation. We will show our strategy's benefits through the mathematical model and the algorithm of the presented problem.

ADAS is the air defense control system performing air surveillance and identification of ROK and near air. This system is self-developed by Air Force, currently operated successfully as the alternative system of MCRC. ADAS processes converting and combining transferred the real time radar data detected by radars. additionally, it displays significant radar data as producing in tracks. Then, it uses the message queue for IPC(Inter Process Communication). the various tactical data processed in the server is ultimately send to the network management process through the message queue for transmitting to the weapon director console. the weapon director receives this transmitted tactical data through the console to execute air defense operations. However, there is a problem that data packet is delayed or lost since the weapon Director does not receive as the amount of tactical data from the server overflowed with air tracks and missions increased. This paper improved the algorism to display and transmit the various tactical data processed from ADAS server to numbers of the weapon director console in the real time without any delay or lost. Improved the algorism, established at exercise, the development server in the real operation network and the weapon director console, is proved by comparing the number of sending tactical data packets in the server and receiving packets in the weapon director.

In the defense field, weapon systems are increasing in importance, as well as the weight of the weapon system embedded software development as an advanced technology. As the development of a network-centric warfare has become important to secure the reliability and quality of embedded software in modern weapons systems in battlefield situations. Also, embedded software problems are transferred to the production stage in the development phase and the problem gives rise to an enormous loss at the national level. Furthermore, development companies have not systematically constructed a software reliability test. This study suggests that approaches about a qualityverification- system establishment of embedded software, based on a variety of source code reliability test verification case analysis.

A military shelter for communication and information is necessary to optimize the integrated combat ability of weapon systems in the network centric warfare. Therefore, the military shelter is required for EMI shielding performance. This study examines the stable measurement points for EMI shielding effectiveness of a military shelter for communication and information. The measurement points were found by analyzing the EMI shielding effectiveness measurement data with data mining technique and process capability analysis. First, a support vector machine was used to separate the measurement point that has stable EMI shielding effectiveness according to set condition. Second, this process was conducted with process capability analysis. Finally, the results of data mining technique were compared with those of process capability analysis. As a result, 24 measurement points with stable EMI shielding effectiveness were found.

Cyber attacks are an important factor that determines the victory and defeat of Network-centric wars in which advanced weapon systems are highly interlinked. In addition the increasing dependability on software as its develop as the latest fighter is demanding enhanced security measures for fighter software to Cyber attacks. In this paper, we apply the DO-326A, which is an airworthiness security certification standard, to design a risk-based security threat assessment process by reflecting characteristics and operational environment of fighter aircraft. To do this, we add the following steps in security threat assessment stage of DO-326A's airworthiness security certification process. First, we derive security threats of fighter. And then, we scored the security threat in terms of possibility and impact on the fighter. Finally, we determine the security risk severity.

Christian communities have long sought to find what type of moral judgment is appropriate and what the Christian behavior is, by taking the church's ethical norms and behavior patterns as objects of reflection. In the same context, Christian education also tried to base the psychological rationalism of J. Piaget and L. Kohlberg, but the reason-centered structural development theory was not the answer. In fact, the structural development theory, which emphasized autonomy while excluding emotions from the moral judgment process, over-emphasizing cognition or reason, eventually led to moral relativism, unlike what was intended. In addition, it was criticized for not being able to adequately elucidate the gap between human moral reasoning and behavior, and for attempting to interpret morality excessively within the context of social culture. Recently, these limitations of structural developmental theory have been reinterpreted by neuroethics, especially moral psychology theories, which claim that moral judgment ability is physically wired in the brain and relies heavily on networks between cortical and limbic system. The purpose of this paper is to review some of the newly emerged research themes of neuroethics, and then to discuss two main theories that explain morality in the perspective of neuroethics and the implications that Christian education should pay attention to.
