We are leaders of "ET Association" that is the association for study of engineering ethics that is in Chubu Blanch of IPEJ (the Institution of Professional Engineers, Japan). We have held for the first time "Technology Cafe" series four times from this April to July. That theme was "The public and engineers thinking the view of "safety and mind-peace"". This movement is a science & technology communications for public by engineers, similar to "Science Cafe" that scientists are primarily doing, Also, "Technology Cafe" is scheduled after October to continue. I'll report on that first approach and results with this paper.
