This study provides the method to build the rotor system model using dynamic analysis software. also, it introduces the traditional methods of the rotor system modeling and informs the each merits and demerits. We will make up the flexible system of rotor system model with ADAMS, multi-body dynamics S/W, in order to develop dynamics model and get the response of plant model near to real model through connection the SIMULINK of MATLAB. We will develop the computing dynamics-controling model possible controlled simulation similar to a real model with controlling the plant model.

This paper will present an epidemiological information aspects of Japanese encephalitis in Korea of the past ten years from 1971 to 1980 and the medical statistical observation on the relative factor of Japanese encephalitis. It hoped that the information will be used for reference in future endeavors of study in the follows: The obtained results were as follows: 1. The mean of the incidence cases of Japanese encephalitis in Korea from 1971 to 1980 was 94.2±24.6(S.E.), that of incidence rate per 100,000 was 0.26±0.07 (S.E.) and that of case fatality rate was 3.6±0.89 per 100 cases. 2. The highest incidence cases of Japanese encephalitis could be found in younger whose age under 19 years old, which accounted 96% of the total incidence cases. 3. The correlation coefficient between the incidence cases of Japanese encephalitis and number of vaccinated in man was r=-0.416, its and pesticide consumtion amount was r=-0.432 and its and number of pig vaccinated was r=-0.485. 4. Correlation coefficient between year after imported and positive rate of HI test of Japanese encephalitis was r=+0.976.
