Introductory quality engineering education was studied. There has been much dispute regarding this type of education, in which the participants must struggle to make the initial paradigm shift. Quality engineering instructors have had much difficulty in motivating their students to take up quality engineering. This study identified current problems in introductory quality engineering education. In particular, instructional materials that will efficiently show the effectiveness of quality engineering and enable students to be educated effectively were studied.

Recently the design of experiments is used to decide optimum processing conditions. However when the control factor interaction between the several control factors becomes large, the calculated accuracy using the design of experiments becomes very bad. Then everybody should check the results regarding the best and the worst conditions in the experiments. If differences between the calculated vale and the experimental value for the best and the worst conditions become large, the results using the design of experiments are never used. Therefore, in the previous research, we have developed the tool for easily finding the control factor interaction in the design of experiments. This control factor interaction between the several control factors action is large fault, an obstacle for innovation and disliked by everybody. However when the reaction between the several control factors becomes large effect which is surpassed the estimate, the control factor interaction becomes the synergistic effect which is liked by everybody, the synergistic effect finally brings large profit, excellent license and innovation. Therefore in this research, the tool for easily finding the synergistic effects between the control factors was developed and evaluated using the program in the previous research. The program was the tool for finding the control factor interaction in the design of experiments, it was improved for the easily finding the synergistic effects by using the new algorithm, and was evaluated by the several mathematical models and the experiment. It is concluded from the result that (1) the new program can clear the synergistic effects between the control factors, (2) the program also can clear the complex multiplier effects and (3) the program can clear the synergistic effects with innovative profit in the actual example.

Earthquake prediction by the MT-system was proposed by Genichi Taguchi in 1995. Studies started in the Yano laboratory at Tokyo Denki University in 2004 demonstrated that earthquake prediction was possible to some extent, but there was considerable prediction error. A new study was started in line with new developments in the MT-system. Data collection was started in Tsukuba district. This paper gives a periodic analysis of seismic waveforms in the Tsukuba district and obtains the distances of ground vibrations by using the RT method, with the variance of the period as an attribute. The possibility of prediction by a further two-tail T method is shown, based on the variation of the distance over time. The estimated S/N ratio was -0.176 db and the sensitivity was 0.016 db. The prediction error was ±10% at a vibration velocity of 20μm/s.
