current mine detector can't division the section if it is conducted and it needs too much labor force and time. in addition to, if the user don't move the head of sensor in regular speed or move it too fast, it is hard to detect a mine exactly. according to this, to improve the problem using one direction ultrasonic wave sensing signal, that is made up of human body antenna part, main micro processor unit part, smart glasses part, body equipped LCD monitor part, wireless data transmit part, belt type power supply part, black box type camera, Security Communication headset. the user can equip this at head, body, arm, waist and leg in removable type. so it is able to detect the powder in a 360-degree on(under) the ground whether it is metal or nonmetal and it can express the 2D or 3D film about distance, form and material of the mine. so the battle combats can avoid the mine and move fast. also, through the portable battery and twin self power supply system of the power supply part, combat troops can fight without extra recharge and we can monitoring the battle situation of distant place at the command center server on real-time. and then, it makes able to sharing the information of battle among battle combats one on one. as a result, the purpose of this study is researching a smart wearable mine detector which can establish a smart battle system as if the commander is in the site of the battle.

현재 국내 e스포츠 시장 규모와 사용자들이 지속적으로 증가되고 있는 시점에서 배틀그라운드라는 게임이 e스포츠 시장에 진입하였다. 배틀그라운드가 현재 e스포츠에 끼치고 있는 영향이 크지만, 좋은 반응을 유도하지 못하고 있다. 본 논문에서는 좋지 않은 평을 받고 있는 배틀그라운드의 e스포츠화와 과거의 스타크래프트, LOL(리그오브레전드)과는 달리 배틀그라운드가 흥행하지 못하는 이유와, e스포츠에 적합한지를 연구하고, 차선책을 제안한다.

The Lanchester equations are widely used for modelling the direct-fire land battle. However, it is recognized that the Lanchester based models are less applicable to direct-fire land combat when the battle size is small, the forces are near parity or the inter-firing times of the combatants do not follw a negative exponential distribution. A comprehensive investigation has been conducted to establish the circumstances under which the Lanchester based models are applicable.

Recently, the mobile game market is growing due to the extension of mobile devices and internet. The mobile games are became a popular culture in society. But the existing mobile games have two simple forms. There are tow models in the mobile games. The first is as follows. The user downloads a game one time and play the game at off-line field. The second is as follows. The user play a battle game at on-line field. In the paper, we propose a new on-line "tug of war" game model which the user can play two kinds of game. They are the on-line battle mode game and the character raising mode game. Thus, this game model is different to existing mobile games and innovative model in mobile game market. This paper proposes a new research field in mobile game market with the characteristic that the user tan play two modes. One mode is the on-line tug of war battle mode and the other is the character raising mode.

"History is a mirror" means that we should be prepared for the threats of enemies through learning from repeating history. Currently South Korea is facing various provocations, including North Korea's nuclear weapons and missile s. For the protection of the life and property of its people, South Korea should regard North Korea as a main enemy and be fully prepared for the threats. The Korean War was a war between well-prepared North Korea and ill-prepa red South Korea. After Liberation, North Korean army incorporated the Chinese Communist army, placed battle equi pment with the support of the Soviet army, and finished corps-level training while South Korea at that time did not finish battalion-level training. In wartime and peacetime, an army should improve military security by concealing its own information and find its enemy's information. North Korea carefully prepared for the war, collecting information about the organization, deployment and operation of the South Korean army. South Korean army failed to cope with it and had hard times in its early battles. In this paper, I will emphasize the importance of military security, focusing on the Battle of Gaeseong, the early part of the Korean War.

A threat evaluation is the technique which decides order of priority about tracks engaging with enemy by recognizing battlefield situation and making it efficient decision making. That is, in battle situation of multiple target it makes expeditious decision making and then aims at minimizing asset's damage and maximizing attack to targets. Threat value computation used in threat evaluation is calculated by sensor data which generated in battle space. Because Battle situation is unpredictable and there are various possibilities generating potential events, the damage or loss of data can make confuse decision making. Therefore, in this paper we suggest that substantial threat value calculation using learning bayesian network which makes it adapt to the varying battle situation to gain reliable results under given incomplete data and then verify this system's performance.

This study is to apply the Quality Function Deployment Methodology to select the Navy Battle Lab location among possible location sites. The Quality Function Deployment is known to be one of the good methodology in reflecting users' need. Thus the Navy Battle Lab location should b e selected on the basis of satisfying the Navy and ADD requirments. The data to be applied in QFD has been collected from the Navy users and ADD researchers. After carrying out QFD procedures, Jinhae was selected as the best site of the Navy Battle Lab.

This study extends the existing method of Technology Forecasting with Data Envelopment Analysis (TFDEA) by incorporating a ranking method into the model so that we can reduce the required number of DMUs (Decision Making Units). TFDEA estimates technological rate of change with the set of observations identified by DEA(Data Envelopment Analysis) model. It uses an excessive number of efficient DMUs(Decision Making Units), when the number of inputs and outputs is large compare to the number of observations. Hence, we investigated the possibility of incorporating CCCA(Constrained Canonical Correlation Analysis) into TFDEA so that the ranking of DMUs can be made. Using the ranks developed by CCCA(Constrained Canonical Correlation Analysis), we could limit the number of efficient DMUs that are to be used in the technology forecasting process. The proposed hybrid model could establish technology frontiers with the efficient DMUs for each generation of technology with the help of CCCA that uses the common weights. We applied our hybrid model to forecast the technological progress of main battle tank in order to demonstrate its forecasting capability with practical application. It was found that our hybrid model generated statistically more reliable forecasting results than both TFDEA and the regression model.

In this paper, we review the characteristics of battle field, consider required properties of mobile radio network, and design network control architecture proper to battle field network. Also we design distributed algorithm which constructs network control architecture and transmission schedule. For the information of network connectivity and the immediate reconfiguration caused by failure, loss, or movement of nodes, configuration and transmission schedule, algorithms are to be executed periodically and for entire network reliability, algorithms must to be executed fully distributedly. At the time of loss or failure of primary local control node, we suggest the method which diminishes transmission delay. We explain the operation of network with examples. Finally designed algorithms are verified and analized by computer simulation.
