This paper is a sort of implication analysis of Korean War, and the study was conducted by investigating ``East-West Cold War Regime`` located upon Korean War, that is to say the conflict between USA and USSR. The result of investigation about the USA military policy and a series of war plan against USSR from 1945 to 1950 is as follows; Why did USA conduct the Korean War in accordance with the ``Far-East War`` and give up noninvolvement policy and also engage so rapidly in Korean War? We can understand the reason easily by looking at ``Acheson line`` from military doctrine point of view. During the Korean War, all operation orders including ``Incheon Landing Operation`` were issued by GHQ/FEC, not UNe. GHQ/FEC continued to issue the order even after establishing UNC, that means USA considered the Korean War in accordance with ``Far-East War``. The map-4[blockade line] shows the fact that USA engaged military forces in the Asian Continent at Korean War. It tells USA holds Japan of inner blockade line and less Hokaido and secure Okinawa. By the simple expression of the map, we may come to the conclusion that USA considered Okinawa the security zone of it`s survival. Although USA considered Japan the ``FEBA``, the fence of Pacific defense and could give up Japan. Also Korea looked alike ``GOP`` in military doctrine. Usually, the role of guard zone(GOP) is assuring the ``FEBA`` forces to have a plenty of time to prepare combat. We can understand easily the meaning of rapid commitment of USA through applying military doctrine. And also it may be because the opponent was not USSR, but North Korea.

This article proposes a new technique for the reduction of vibration and noise in the geared system by adjusting the distance between gear shafts. The vibration and noise may be produced by the abnormal force applied to the tooth face. And the force may be the cause of ununiform velocity in the driven shaft. If the velocity is obtained to be uniform by adjusting the distance between shafts. the vibration and noise may be reduced to some extent. In order to review, a dynamic analysis model for the gear train used in a mill turret and a test rig are developed. The velocities in the driven shaft are calculated by dynamic simulations for the model and noises in the test rig are measured with varying of the distance between shafts. The comparison of simulation and test data shows that the distance between shafts at the most uniform velocity has the lowest level of noise.
