This thesis aimed at studying the development of the engineering manpower in industrial society today. In order to achieve the purpose, we must to be supported by its training to be based on the continuous government planning for the development of manpower It is proper that strategic management should be conducted for the vocational engineer training. In the view of the present situation, we dare assert that the following management should be followed ; 1. We believe that the motives of the engineer will be caused by the law of official rearing, 2. For the manager's concern, it is need for the system of accounting in the manpower to be established, 3. For the efficiency each other, it is urgent to take a trianqular position for the confidence through the value of rationalism above all mentioned words are concerned with having high morale and a normal act for the engineer.

To theoretically predict knock occurrence in S. I. engine as a function of engine design and operating parameters, transient local temperature and pressure, mixture density of flame front in combustion period are calculated. We next determined normal combustion period and auto ignition period of end gas using the prediction method on occurrence of spark knock which we suggested. We predict knock occurrence in S. I. engine by comparing consecutively normal combustion period with the auto ignition period of end gas in combustion period. Engine design and operating parameters such as compression ratio, engine speed, spark timing, inlet temperature and pressure are taken into account in this calculations. The predicted result are well matched with the experimental results in turbocharged engine. Therefore, this method will provide the systematic guideline for designing engines in view of knocking limits.

Recently the road traffic noise has appeared as a significant environmental issue because of dramatic increase of vehicles and expansion of newly constructed road. Therefore, this study proposes the method that improves prediction factors and models through analysis of the existing road traffic noise prediction model. Prediction factors can be improved by establishing guideline for diffraction attenuation and applying daily traffic discharge, peak traffic discharge, and average traveling speed through an analysis of level service. Prediction must be made by periods of one or five years during 20 years. Prediction models also can be improved to include better prediction model through setting the database, establishing functional relation between physical properties and noise levels by acoustic analysis, and developing models for road traffic noise prediction in residential areas.
