The heavy thermal load to battle tanks can cause electronic components' malfunction and crew to be put out of action. The thermal load is generated from Internal heat sources such as electronic devices installed in the room as well as extremely hot weather. In this study, heat and flow analysis for the cabin room of a battle tank was performed to deal with this thermal problem. This study presented the validation of simulation results in comparison with those of test, the investigation of optimal flow design for effective cooling in cabin room and finally the evaluation of thermal comforts to crew.

Ever though the authentic history on the first war between Kokurye and Sao-dynasty is not good enough. there are many kinds of suppositions and debates upon this war in the current history books. This study gathered current and old historical records and analyzed the next five results. First. Chang-rna (the rainy season of Korea) had a great effects on the battle. Second. unlike the authentic history. the war seized not only the effect of Chang-rna but also the battle action. Third, battle field is supposed have been in Im-yu-goan. Fourth, the Kokurye force did not come across the Chang-rna but made a great victory by using it intentionally. Fifth. there was a great strategist at that times whose name was Kang-Ie-Sik. But. in spite of many positive records there is little doubt on that he was the commander of the Im-yu-goan battle.

The purpose of this research is to reevaluate the success factors and significance of the battle through the analysis of the only successful Chuncheon district battle during the defense combat in the early part of the Korean War on June 25, 1950. The research results are the matters that are analyzed from the viewpoint of the armed forces of the Republic of Korea, focusing intensively on the successful aspect of the early defense combat against North Korean army's surprise invasion of the South and on the battle that thwarted the North Korean army's intensive surprise attack intention. This research attempts to reanalyze the Chuncheon District Battle in connection with the Kim Il-sung's strategic course of action in consideration of the operation plan of North Korean invasion of the South. In other words, it is to reanalyze the enemy tactics in connection with North Korean army's plan of invasion of the South. The fact that the 6th Division of the armed forces of the Republic of Korea destroyed the North Korean army's operations plans that were in accordance with Kim Il-sung's strategic plans has more significance than a simple tactical success. The Chuncheon District Battle should be reevaluated as the "decisive battle" which went beyond a successful early defense combat in a Chuncheon region, and which fundamentally defeated North Korean army's war plan itself by thwarting the Kim Il-sung's strategic plan.

It depend on relative combat power, patriotism and cohesion of citizen to victory in the battlefield. This stu dy try to analysis why the Germany army fail 'the Battle of the Bulge'. The Germany army plan of maneuve r to attack the France army was surprise attack in the beginning of World War II. The Germany army have initiative to make breakthrough Ardennes Ridge. The operation of the Ardennes Offensive Operation and the Battle of the Bulge is the typical features of blitzkrieg shock. However, the results are extremely different. In the course of the operational planning and decision the course of action, military security is most important fa ctor. We can see the truth in 'the Battle of the Bulge'.

There are many battle paintings among wall paintings in Kokuryeo. Most warriors in paintings wore armours in full kit. Armours in Three-Kingdom Period were contrived for strategy. They have been checked that Pangab suitable for infantry action had been worn in Shilla while flexible Chalgab for cavalry battle had been worn in Kokuryeo. As cavalry strategy in Kokuryeo was brought to Kaya Kingdom via battles in fifth century, Chalgab became also worn in South area. Pangab, Shaejagab and Nubigabot as well as Chalgab had also been worn on view of wall paintings. There were many kinds of helmets such as Jongjang-panju, Mangokjongjang-panju, Kwanmonhyoungbok-balju, Chongkakju and Kwaehyoungju. Accesory-Armours are Sanggab, Kyounggab, Sangbakgab, Gwinggab, Daetwaegab and Kyounggab. Those helmets and Accesory-Armours are quite similiar to excavations from Shilla, Kaya Kingdom area. As Kokuryeo wall paintings are related to excavations from South area, armours and helmets in those wall paintings can be a good data to investigate the full shape of excavations and how to use, while excavations are very useful to the study on method of construction and manufacturing of armours and helmets.

The movie, Battle of Wits which is based on the cartoon by Morihideki(森秀樹) is directed by Zhang Zhiliang(張之亮), a director from Hong Kong. Morihideki's cartoon is based on the novel by Sakemikenichi(酒見賢一). The movie represents a successful one-source multi-use case. Battle of wits, which deals with the Mozi's propaganda against war, presents the thought of Mozi School(墨家) in spring, autumn, and warring states. The movie criticizes aggressive war by powerful nations. Aggressive war is an extreme form of brutality and worthless action without any benefit. Aggressive war represents 'never each love(buxiangai, 不相愛)' and 'never each benefit(buxiangli, 不相利)' as understood by Mozi. The main character of the movie endeavors and successfully defends the enemy's attack as Mozi did. It is due to the propaganda of Mozi School 'not to attack(feigong, 非攻)' that they can defend themselves from the attack from a powerful nation. It means that 'the universal love(jianai, 兼愛)', the ideology of Mozi, is concretely actualized. The philosophy of Mozi School in the Battle of Wits has its limits as follows: the thought of Mozi School is just suitable during times of war and unnecessary in times of peace, the contradiction between universal love and hatred for one person; the Mozi School's faith in the nature of human beings to confront betrayal. This limit was also proposed in the movie. However, the movie presented how the masculinity of Mozi School, supplemented by the feminity of Daojia(道家), can succeed in achieving genuine communication. When focusing on this point, the movie can be interpreted as biased towards the philosophy of Daojia.

Purpose: In this study, we apply environmental stress screening (ESS) to battle management system (BMS) of a tank and use the ESS profile based on production process data, guided by MIL-HDBK-781/344/2164. Methods: To optimize ESS Profile of the BMS of a tank, we estimate ESS model parameters (e.g., defect density, screening strength) using primary production failure reporting and corrective action system (FRACAS) data of military supply contract firm. Results: First, we collect the Primary production FRACAS data of military supply contract firm. Second, we compute curve fitting approach to find patent defect density and latent defect density using FRACAS data. Third, we solve the equation of Defect Density(patent defect density + latent defect density)($D_{IN}$) and Screening Strength(SS) Using second step data. As a result of analysis according to the order, we calculate $D_{IN}$(Temperature stress case : 74.02, Vibration stress : 10.252) and : SS(Temperature stress case : 0.4632, Vibration stress : 0.4142) and confirm the Condition II-D based on MIL-HDBK-344. According to Condition II-D, it is necessary to modify existing ESS profile through decreasing the $D_{IN}$ and increasing the SS. Conclusion: Identification of defect causes through ESS approach reduce defect densities for production. It provides feedback to a lessons-learned data base to avoid similar problems on next generation tank BMS.

This article studied that the characteristics of the movement image shows clearly through the controlled movement which the experimental short animation film shows. Animation makes the short edit like live action film. In addition animation shows the movement image positively by redefining the relationship between the frames. By using the concept of the movement image, this article says the movement in animation is not only the technique but also the essential factor which makes the audiences recognize animation and causes emotion in them and the important factor which reveals the meanings of each animation.

The principle of Effective Based Operation applied to the Korean Theater resulted in measurable effects to win the minimum battle. Based on the finding, this study recommends the effect analysis methodology under the V-C interoperability system to acquire a weapon system. This method is followed as below; to confirm the effect data on the organized weapon system, to set MOE, MOP and effect considering the purpose of the analysis, to apply the appropriate operational concept and scenario on the weapon system, and then the available C Model is after action reviewed, adjusted, and given feedback. The V-C interoperability system enables to perform the real-time combat experiment under the virtual synthesized battlefield circumstances. The defensive battle organization and displacement of the future anti-tank guided weapon system was considered in the modeling process. Scenario was written, which encompasses company-level units and the battalion-level operation. Then the available AWAM was embodied and effect-analyzed, which formed the foundation of SBA.
