Research paper : Acquisition of skills on the shop-floor (N. Matsuki)−84−Synthesiology - English edition Vol.3 No.1 (2010) the rural areas to work in the large cities. I think we have come to the end of the age of manufacturing where high school graduates are called skilled workers while the college and graduate school graduates are called engineers. At the same time, the mass media message saying that the expert artisans of the family-run factories support the Japanese manufacturing industry must be corrected. While their role is not small in terms of required precision and cost, the future cannot be warranted by exaggerating the image of the artisans.Finally, I shall discuss to whom the expert skills belong. Discussion on the possession of invention by the corporate researcher started with the blue diode incident, but the possession of the skills of the expert skilled worker is hardly discussed. When the skills for processing that was cultivated carefully over time is converted to technology, is the skilled worker left with nothing? Recently, the problem has been raised on the outflow of skills when the corporate retirees are invited by foreign companies to provide local training overseas. However, we must first discuss the subject of the possession of skills. I think there must be serious discussion by various parties involved.6 ConclusionThe outline of the research scenario for the acquisition of expert skills and the results of the research were described. The results obtained in this research are as follows:(1) The method by computer system construction as an alternative of the expert skilled worker was proposed for skill acquisition; and (2) The alternative computer systems including the ones based on theoretical formula, experimental formula, and data mining were described.We also discussed the position of expert skills in the future manufacturing industry.The Digital Manufacturing Research Center has conducted research with the objective of “studying manufacturing scientifically.” I think the R&D for the acquisition and the visualization of expert skills has clarified the relationship between expert skills and manufacturing better than ever before.Fig. 7 Expert skill in casting and its visualization.01234567891004000600080001000012000140001600018000200002000TimeTemporal change of load on ladleLoadM.

It was unclear at what point this view was taken, and the paper was revised to clarify that point.2 Changes in setting of the scenario to match the actual situationQuestion (Kazuo Igarashi, Measurement Solution Research Center, AIST)You wrote that the direction was shifted to create an effective tool and allowed the use of methods outside the initial scenario because the initially set scenario could not be executed by ignoring the demands on site. However, estimating from the content of the factors that prompted the change, I think the items described here are important subjects that should have been
