Impatience characteristics are an important factor to be considered in the defense field, which is sensitive to time, but there are not many cases applied. In addition, due to the difficulty of analysis that must consider various probabilistic factors (breakdown/maintenance distribution, impatience characteristics, etc.), military decision makers consider only simple data (number of occurrences per year, maintenance time, etc.) Therefore, in this study, a model capable of analyzing the performance of the emergency maintenance system for determining the appropriate size and organization of military and civilian maintenance personnel was presented in consideration of impatience characteristics and probabilistic factors. And through numerical analysis, the appropriate size of the military and civilian emergency maintenance teams was analyzed. This study is significant in that it can improve readiness of operational power and prevent waste of defense budget through efficient operation of the military's emergency maintenance system.

In this paper, we propose a new data-mining-based methodology for military occupational specialty assignment. The proposed methodology consists of two phases, feature selection and man-power assignment. In the first phase, the k-means partitioning algorithm and the optimal variable weighting algorithm are used to determine attribute weights. We address limitations of the optimal variable weighting algorithm and suggest a quadratic programming model that can handle categorical variables and non-contributory trivial variables. In the second phase, we present an integer programming model to deal with a man-power assignment problem. In the model, constraints on demand-supply requirements and training capacity are considered. Moreover, the attribute weights obtained in the first phase for each specialty are used to measure dissimilarity. Results of a computational experiment using real-world data are provided along with some analysis.

In next war, it will be expected that some requirement such as information acquisition, battlefield surveillance and control, increased power projection, precision attack by guided missile and electronic warfare may have special importance. The use of robot weapon system by Airforce will make up for some weak points of man based weapon system that Airforce currently has. And Airforce man/robot combined air vehicle weapon system can extend military operational theater and give its flexibility in next war where power, mobility and information should be all-in-one for military purpose.

A military uniform has two basic characters. One is functionality for field warfare and the other is decorativeness to express dignity and power to maintain systematic organization. For these purposes, the military uniform is maximizing its effects on functionality and decorativeness on each aspects of material, color, dignity, item, military ornaments and accessories. During wartime, the military uniform improved its functionality and gave much influence on normal clothing at the same time either directly or indirectly. Military look became more diverse. In a mood for the end of century and inflated material civilization, and with nostalgia for the fast, mixed styles of fast, presents and future have come out in variety. In Street Fashion, there are many alternative trends to meet diverse desires of teenagers, and the military look has been steadily favored. The functionality and the decorativeness of military look would have met fashion sense and taste of younger generations pretty well. First, teenagers are active, and the practical materials and functional designs of military style applied to their clothes. Second, they prefer challenging and creative styles, and the decorative elements of military clothing for the colors, patterns, accessories have been applied to they clothing. We may need to understand their culture and emotion more closely and help them enjoy sound and beautiful clothing culture. The military uniform adapted itself to natural and social environments and has been developed and improved, which made that possible.

The conjugate heat transfer from the simulated module in a horizontal channel with the variation of inlet air temperature is experimentally investigated. The aim of this study is to estimate temperature difference between a module and inlet air. This study is performed with the variation of parameters that are inlet air temperature(Ti=25~$55^{\circ}C), thermal resistance( $R_c$=0.05, 4.11, 158 K/W), inlet air velocity(Vi=0.1~1.5m/s), and input power(Q=3, 7 W). The results show that the effect of inlet air temperature is little, at the case of using conductive board. And input power was most effective parameter on the temperature difference between module and Inlet air.

This thesis is to make an appropriate national defense policy of Republic of Korea through studying the Hegemony Strategy of United States. I searched the theory of hegemony. The hegemony was differently defined by the point of time and region. The strong power nations with the hegemony have been making efforts to maintain their hegemony everytime. I have conclusion that the presence of hegemony once emerged, it brought regional stability in place whether it is coercive or beneficial. The stability and instability of international order IS not exclusively dependent on hegemony. Even if the safety of hegemony cannot guarantee absolute stability of international order, there IS on doubt that the hegemony has enormous impact on that. According to the hegemonic theory, the history of mankind equals to the history of rising and falling hegemony. The international order was changed as the hegemony changes. The United States has been making efforts to maintain her global hegemony during the post cold-war era as well. Taking all these into consideration, relevant military strategy direction able to pursue national interest is that to make up for the relative weakness in the strategic environment. South Korea have to prepare security policy response as following. First, South Korea should build the military force equipped with advanced weapons in military technology sector and solidify military diplomatic relation able to form cooperative relation in wartime. Second, South Korea should make solid Alliance of Korea and U.S. Third, develop and maintain multilateral security cooperation of East Asia. Forth, we could realize that there are means that can neutralize opponent's strong point by seeking one or two and more asymmetry in the aspect of strategy, tactics, and means through asymmetric strategy. Than the military force of South Korea should develop into a force that is able to overcome to the traditional North Korea's threat and new type of conflicts. And the force should have sufficient strength and be deployed to effectively defend the Korean Peninsula. So, we need to establish a denial and defense system against any hostile neighboring country. Therefore, ROK military forces preparing for the future should try to construct a future military power to gradually establish enough strength for self-defense to prepare for a uncertain security environment and when the Korean Peninsula is unified in a future.

The Republic of Korea, ranked as the 5th military power according to the size of its ground troops, discharges more than 200,000 manpower to the society annually; more than 13,000 of them are officers. The re-employment rate of discharged military personnels, who experience early retirement of 5 to 15 years compared to general public officers, is very low, only amounting to 53.2%. On the other hand, major developed countries exhibit great national scale of effort to take responsibility in helping the settlement of the soldiers who have dedicated their career for their countries. The re-employment rate amounts to 94%. Fully acknowledging such disparity, this paper examines various policies on discharged members support of developed countries, and aims to suggest developmental model on employment support designed for discharged members in the Republic of Korea.

This thesis is the result of the study about 'How we should develop the human resources program to gain human strength in the strategic environment of the future?' Once again, regional stability is interdependent with economic stability, political stability, and military stability of all the factors in the region. History shows that if a militarily capable regime lacks economic resources, then there is political pressure on the regime to use their military to acquire needed resources. The purpose of this study is to find the way that how to gain excellent human resources now and in the future. Military man power should be strong whenever. The Ministry of National Defense has "Reform Military Structure Plan". The focus of this Plan is Korean military strategy in the situation of the confrontation between South and North Korea and in the situation of the international relationship and the way of constructing the military strength for the future. To study these subjects, I reviewed the theories of "Acquisition Program of Human Strength" were developed and assessed the future strategic environment of the Korean Peninsula. From these studies, I suggest that The Ministry of National Defense should pursue preparing for the future military strategy and military structure. we should be skillful in supplementing the Human Strength. We should study about Military Revolution Plan and Human Strength structure for the future.
