This study aims definition of complex phenomena arising under screw thread fastening process and deep understanding of past relevant knowledge. So far, authors have been studied on screw fastening mechanism of a clamped body with M10 bolt-nut by using 3D elastoplastic FE analysis. In this paper, more precise analytical model is developed and the bolt-nut fastening process is calculated. Consequently, following matters were revealed. (a) Greatly complicated deformation of bolt-nut joined threads area under contacting was clarified qualitatively. Supporting contribution percentages of each thread to axial load was calculated; especially the first thread of joining screw thread supported about 31% of axial force. (b) Spring constant of bolt-nut or clamped part calculated by the present FEM was well accorded with some theoretical equations within 7% error. Contribution of elongation of each region with the bolt also agreed with these equations. Most of all, the validity of Sawa-Maruyama's equation was showed. (c) During fastening process, development of stress or strain at the bolted joint was visualized compatibly alongside of past knowledge and information.

Tremendous developments in science and technology have brought prosperity and an affluent lifestyle to mankind, but scientific and technological progress has also generated social issues related to the environment, security, ethics, and socioeconomic activities. Under these circumstances, a Science, Technology, and Society (STS) education that emphasizes the teaching of scientific and technological developments in their cultural, economic, social, and political contexts is required in order to cultivate human resources capable of making decisions about how to address these issues. In this study, we developed “nocobon,” a game-based teaching material for thinking on STS issues from various perspectives. “Nocobon” is a detective card game that can be played by a group of three to six people. The results of its prototype test for high school students suggest that players could acquire new knowledge and learn to think from different perspectives on STS issues through unlocking the mysteries in a series of “nocobon” cards. The results also indicate that “nocobon” could be a simple and convenient teaching material from the viewpoint of the time management.

Although the number of foreign visitors to Japan has increased remarkably in recent years, many licensed guides have not been usefully employed. One of the main reasons for this is that there is a problem with the system of producing new work-ready guides in Japan. Currently, the Japanese government only conducts the national examination, and informs successful applicants of a file of associations of licensed guides, which offer several days of basic training to a very limited number of new guides. Most new guides have no chance to take practical training to become a professional guide, and travel companies do not employ them. After examining guide systems in 54 countries and regions, I found that the following points are essential to a system which produces new work-ready guides: (1) A system which issues a license after several years of training, following a final examination (2) A license renewal system to secure the quality of a guide A system with these elements must be employed immediately in Japan in order to increase the number of a high-quality qualified guides, and to meet the strong demand from the inbound tourism industry.
