  • In this study, in terms of the exercise vehicles of the weapon systems having negative buoyancy, the analysis on the operation concepts was performed and the new methods of floating to surface were proposed. In case of having negative buoyancy, the additional methods for recovering the exercise vehicle have to be considered. As parts of recovering the exercise vehicle, for floating to surface the new methods of weight discharge, weight separation and sea water discharge were proposed. The conceptual design about sea water discharge method was performed. It was confirmed that those methods could be applied to the design of the exercise vehicle having negative buoyancy.

  • North Korea has recently developed and deployed missiles with various ranges as asymmetrical forces. Among them, short-range ballistic missiles with improved accuracy are expected to aim at achieving tactical goals by hitting important military facilities in Korea with a small number of missiles. Damage to the air force airfields, one of North Korea's main targets of missiles attack, could limit the operation of air force fighters essential to gaining air superiority. Based on the attack by the short range ballistic missiles, the damage probability of military airfields was simulated. And as the one of the concepts of passive defense, the way to reduce the loss of combat power was studied through the changes of the air force squadrons deployment. As a result, the effective deployment plan could be obtained to reduce the amount of power loss compared to the current deployment.

  • This study examines the training effectiveness of airsoft guns that look and operate like real guns. Airsoft guns were developed in Japan in the late 1970s and are now popular for leisure sports and training, especially in countries where gun ownership is permitted. In particular, Taiwan has been promoting airsoft gun games to train citizen soldiers, and military leaders such as the United States have also utilized airsoft guns for live fire combat training and combat troops' live fire training. However, due to strict usage regulations and the perception that it is a toy, it is underutilized in Korea despite being a good training tool. Therefore, this study will prove the effectiveness of airsoft guns and improve the military's combat capabilities through practical training using airsoft guns. In addition, it will improve the negative perception of airsoft guns and foster a new sports industry.
