Civil petitions and law suits against the military rifle shooting noise have been increased because many military shooting ranges are located near civilian residential area. In order to solve the noise problems, military have devised various methods. In this study, propagation properties of rifle shot through atmosphere were investigated. The military rifle shooting noise level at 5m from muzzle was between $l14{\sim}120dB$ in all directions. The noise level loom both backward and sideward away from system firing range consisting lines of 8 shooting locations were 90dB, when shots were all fired within 10 seconds. At present some of military bases established sound barriers, muzzle enclosures, silencers, and indoor shooting ranges to reduce noises and these prevention methods can reduce noise by $5{\sim}20dB,\;5{\sim}9dB,\;5{\sim}13dB,\;40{\sim}50dB$, respectively. Even though indoor shooting range has the best performance, it requires very expensive construction cost and has short length between target and shooter. In comparison, muzzle enclosure is cheap, but because it is installed in fixed position it can only be used in one shooting position. Therefore a commander should select appropriate methods to reduce military rifle shooting noise considering distance from residential area to the range, mission of military training, budget, etc.

To build an information oriented armed forces, the Korean military telecommunication networks adopt TCP/IP standard communication infrastructures based on ATM packet switched networks. Utilizing this network infrastructure, the Korean armed forces also applies to the areas of battleship management for efficient operation command controls and resource management for efficient resource allocations. In this military communication networks, it is essential to determine the least cost network topology under equal performance and reliability constraints. Basically, this type of communication network design problem is known in the literature as an NP Hard problem. As the number of network node increases, it is very hard to obtain an optimal solution in polynomial time. Therefore, it is reasonable to use a heuristic algorithm which provides a good solution with minimal computational efforts. In this study, we developed a simulated annealing based heuristic algorithm which can be utilized for the design of military communication networks. The developed algorithm provides a good packet switched network topology which satisfies a given set of performance and reliability constraints with reasonable computation times.

After successful nuclear tests Pakistan launched a more severe surprise attack toward India than before. It is highly possible that North Korea will adopt this Pakistan military strategy if it is armed with nuclear weapons. The North Korean forces armed, with nuclear bombs could make double its war capability through strengthening aggressive force structure and come into effect on blocking reinforcement of the US forces at the initial phase of war time. Therefore we may regard that Pyongyang's nuclear arming is a major one of various factors which increase possibility of waging a conventional warfare or a nuclear war. North Korea's high self-confidence after nuclear arming will heighten tension on the Korean Peninsula via aggressive military threat or terror toward South Korea, and endeavor to accomplish its political purpose via low-intensity conflicts. For instance, nuclear arming of the Pyongyang regime enforces the North Korean forces to invade the Northern Limit Line(NLL), provoke naval battles at the West Sea, and occupy one or two among the Five Islands at the West Sea. In that case, the South Korean forces will be faced with a serious dilemma. In order to recapture the islands, Seoul should be ready for escalating a war. However it is hard to imagine that South Korea fights with North Korea armed with nuclear weapons. This paper concludes that the Pyongyang regime after nuclear arming strongly tends to occupy superiority of military strategy and wage military provocations on the Korean Peninsula.

This paper shows procedure and strategies to improve military facilities and local residents' welfare through a civil-military sustainable cooperation project. Military installations tend to impede urban developments, so that a few civil compliant have been often filed. Meanwhile, it is sometimes impossible to relocate military units due to their own unique purpose, even though they belong to core sites of civil developments, which are generally indispensible due to urban expansion, magnified road networks and so on. The solution to offset these conflicts between civil and military demands, which are associated with military units and urbanization surrounding them, is to establish sustainable strategies which enable both civil and military be beneficial. In this study, it is described, decision making procedure to make some facilities of a military unit be better as well as promote local residents' welfare through securing high-quality sports facilities. Delphi-technique and Paired Comparison Method are used to collect civil and military opinions regarding sustainable agreements. As a case study, a civil military cooperation project between a military unit and a local government is introduced. With successful projects, it is expected that the better installations could lead positive images of a military unit, provide advanced athletic environments for both local residents and military personnels, and lessen defense cost to maintain them. Moreover, this project will go down as a paragon of civil military sustainable cooperation.

In case of the construction equipment using by the military camp, such equipments are different from those equipments using at general construction site, of which muffler(silencer) is attached at the passenger seat side, since such equipments are obsoleted, it is great part that a considerably loud noises are continuously diffusing. When working, such noise can be influenced a lot of effects to those working soldiers nearby the equipment, and though it is really terrible loud noise as much as can arise a civil complaints by neighboring civilians, but because its specialty of the military, it is real state that there are many difficulties in establishing an effective soundproof countermeasure due to study shortage and lack of the relevant material regarding to military construction equipment. Accordingly, this study has ever grasped the characteristics of noise by its each frequencies and by distances about those 9 kinds of construction equipments using chiefly by the military camp. As the result, it was known that the military construction equipment is generating the loud noise which can influence bad effect to the workers, and such high sound pressure level of low frequency band can harm even to far distance.

Since military weapon accidents or breakdowns are directly linked to enormous damage, it is important to analyze the causes of weapons system accidents. Recently, in the defense sector, there have been cases in which budget has been saved through analysis of the causes of frequent breakdowns and improvement activities that have occurred in the process of operating weapon systems since 2015. But due to the nature of the defense sector, it is not easy to collect data and studies on weapons system accidents have been insufficient so far. Therefore, this study aims to investigate the causes and types of military weapon accidents by collecting military weapon accident data for military weapon systems and analyzing trends by weapon system classification through the analysis process. It analyzes statistically and visually through social network analysis, NodeXL. It is expected that this study will help improve the stability of the weapon system by reducing the number of military weapon accidents and failures.

Information technology (IT) convergence have been recognized one of the key drivers in the industry perspective. Especially, IT convergence have been one of the most important innovative way for defense sector. Korea government established IT convergence policy in 2008 and have been applying it to the core industry such as automotive, shipbuilding and defense industries. Recently, the creative vitamin project has been launched. Vitamin 'D' means the way to create the value of defense industry. This research analyzes and evaluates various IT convergence business models based on an operation of defense IT convergence center from 2011 to 2014, which is the industry IT convergence centers. Defense IT convergence business models can be classified into four types of mission area as follows : weapon acquisition and management, military intelligence, military power construction, and resources management. We define the concept of defense IT convergence and describe the framework and processes for applying IT to the defense sector. We analyzes and evaluates various business models designed through defense IT convergence framework and processes.

President Lee, Syngman was ROK supreme commander at the Korean war. But, it is doubt that he executed his authority and responsibility by the ROK constitution and law. At the phase of the Korean War conduct, his role may be divided into 'military operation execution one' and 'political-diplomacy one'. He appointed unqualified person to the important position of the national defence, didn't make war execution system, and was not make to meet the war. And, after transferring the ROK force operation commanding authority to the Commander in Chief, UN Command, his role was extremely trivial at the military operation execution phase. Any way, he intended to recover the inferior national strength and military capacity with USA aid, and concentrated his effort toward diplomacy with USA. At last, he succeeded in making a mutual defence treaty and gained a big result to harden Korea national security after war. In sum, president Lee was shrewd politician and diplomat than military leader. And, it can be evaluated that he supplemented the lost part of military affairs side with diplomat one.

The medical system of the Central Military Command in the late Joseon Dynasty was practiced by military yakbang (clinicians 藥房), acupuncturists, and horse veterinarians. By analyzing and verifying various literatures, the following conclusions were obtained: 1) In the late Joseon Dynasty, military yakbang prioritized internal medical treatment over surgical treatment. Military yakbang were recognized before military acupuncturists were and had more medicinal gardens. This can be associated with the characteristics of the Military Medical Specialized Book that focuses on drug prescription. 2) The positions of military yakbang and military acupuncturists were not preferred by the Western Medical Offices (洋醫司). For example, in the latter days of King Sukjong's reign, positions were appointed from the Western Medical Offices but, on appeal, outside doctors were included as well. This is understood in terms of salary levels and guarantees of career opportunities. 3) The military acupuncturist was not selected based on ability as per the rules. If that was the case, more military acupuncturists would have been selected as royal acupuncturists (內鍼醫) under the system that continued until the late 19th century. In the future, it is expected that comparative studies will be conducted between local military medicine and the early Joseon's military medicine, thereby intensifying research on military medicine in the Joseon Dynasty.

Housewife plays a significant role in maintaining a health family life. If she can not function adequately due to high stress, it will affect quality of life of the household members. It also interferes with the normal process of family development. Futhermore, dysfunctional family will have effects on morale of the servicemen in military. This is a descriptive study. The main purpose of this study is to compare the level and types of stress between a group of military wives and a group of civilian wives and provide a data which can be used to develop a stress management program. Sample consist with 250 military wives and 250 civilian wives residing in metro Seoul area. Data collection was done during October 4, 1994-November 30, 1994. Stress was measured with the instrument developed by the researcher. The cronbach's ${\alpha}$ score of the instrument was .91. The data was analyzed by using SPSS-PC. The results of this study are : 1. The stress score was 47.09 for military wives, 36.56 for civilian wives. The range of score was 0-192. The stress level of military wives was greater than civilian wives. (t=4.80, P<.000) 2. The rank order of stressors of military wives were 1) move 2) residential environment 3) purchase of house 4) holidays. The rank order of stressors of civilian wives were 1) husband late return after work 2) arguments with husband 3) holidays 4) husband's drinking problem. The result shows that the main stressors of military wives are frequent moves, residential environment, uncertainty of the future, unsafe work environment of husband, and the lack of private life which are all associated with the military. Therefore, it is urgently needed to distribute this facts through military journal to understand the characteristic of the stress of military wives, and to develope appropriate health care program to lessen the stress.
