This study estimates environmental noises and noise impacts on surroundings by relocation of military training center from city central to suburb. Devising noise prevention plans are found to diminish harmful influence and to design noise reduction system. The prediction is drawn in each separation distance. The measurement is conducted during shoot exercise by a light machine gun(M60), an assault rifle(K-2), a Panzerfaust 3 and a recoilless rifle. The measured noise is 103dB(A) at shooting range in military training center, that is very high noise level. The characteristic of shooting noise is momentary and impulsive, also high leveled through all frequency band. And the forecast of noise assessment at the intended area exceeds noise criteria. Consequently, civil complaint is highly expected. Therefore, noise control system is needed for firing range. General methodology, such as soundproof box and barrier can reduce noise level at residential area near shooting range, which is anticipated by simulation.

This article is to review the change of perception of Japanese Army on the public after Russo-Japanese War and its impact on military training system. I Keywords: Total War, military training, mobilization, Training for youths- Japanese War and World War I. Tanaka has been deeply interested in the relationship of between the public and the army earlier on. He regarded the army as a school to train ‘good citizens’ and is also interested in training of young people. After World War I, the thought of Total War System was more and more shaped up in Japan and the efforts to inspire it to the public through trainings were made. Especially the army implemented the military training sessions in all the schools as well as established “Training Institutes for youths” for non-school youth in order to get more suitable citizens for the army. These ideology educations enabled reformation of the public, and which effected positively to build Total War System lead mainly by the army later on.

Since June 25th 1950, the beginning of the cold war (Korean war), Korean peninsula is still in a state of war. Officially South and North Korean government call a truceafter three years from the beginning day, however both countries are still having several combats in these days. So every Korean citizen male has duty for serving military duty and this lasts even after the serving regular military force, as reserved military. Although South Korea is very small country, the size of military is very large so informing all reserved military takes some time. Since this nation is confronting the enemy and considering the global potential threat, South Korean military needs expedite informing system to call up the reserved military to active duty. In this project, the current informing system has been analyzed and compared with the new method which is using social network service such as Twitter. However mobilization order is very critical. So in our new model there are two ways combined. Using twitter to inform and then use traditional ways to finish the order. This method will provide more efficient and accurate way to cover the call ups.
