     This article describes current status and some future issues in education and training of operators for nuclear power plants. Based on the lessons learned from the accidents at Fukushima-Daiichi nuclear station, the regulation for Japanese nuclear power plants has been tightened. Following the tightening of regulation, the education and training of operators has been improved to take suitable counter operations in a design extension event as well as supposed abnormal plant situations. First, this article describes the outline of the new regulatory standards. Then, some examples of the education and training of operators, mainly the education and training menus at BWR Operation Training Center Corporation, are introduced. Some new activities at Japan Nuclear Safety Institute after the accidents are also introduced. A training menu to improve non-technical skills is described as a new trend of education and training of operators. This article concludes to point out some issues to be considered to make the education and training of operators more effective.

     The research group in JSQC for high reliability and safety has already proposed totally 6 kinds checklists in order to confirm and prevent the unfaithful manners inherent in quality management. To make up the checklists, many contents were argued by research members for a long time. Fundamental and important discussion contents were summarize to 10 topics. First half of them have already been reported. They would be useful to understand proposed checklists. Second half of them are conversationally described in this paper. They would contribute to activate quality management by utilizing checklists.

     The meetings of Technometrics research group take place once a quarter. In the meetings, we discuss mathematical statistical methodology and data analysis on various topics of Technometrics. The results produced by the discussion of this research group are opened in various conferences or journals such as Journal of the Japanese Society for Quality Control. In this report, 5 topics recently discussed in Technometrics research group are introduced. We appreciate it if the readers generate interests on our activity by this report.

     Agile software development is one of the keys to achieving digital transformation, but it is not as popular in Japan as in other countries. In Japan, it is considered difficult to perform project management and quality management for agile software development, and this has been a barrier to its spread in Japan. This paper presents an essential approach to project management and quality management when implementing agile software development, and shows its differences from traditional waterfall development or other iterative development. Based on this, we demonstrate how to plan the quality of the software to be developed and how to build its quality, and show that quality management is also possible in agile software development.

     TQM in corporate management is considered to be one of the best practices. TQM is especially popular in the manufacturing industry, but it’s time to think about what it should be in the future. This paper analyzes the manufacturing industry from the viewpoint of a business model and considers the future. It will also analyze the globally successful GAFA from the viewpoint of a business model and explore its secrets. Based on these results, it proposes a business model for the spread of TQM.

     直交対比を用いて自由度が 2 以上の平方和を自由度 1 の平方和に直交分解することで,要因効果の検出力が高まること,さらに,対比を固有技術的意味を持つように設定することにより,直交表や要因配置実験における要因効果の明細について詳細に検討でき,実務的に意味のある具体的な結論を導く方法を提案した.
     シミュレーションの結果から,通常の分散分析に比べ,本法の検出力は相当程度高くなり,母平均も不偏推定できることがわかった.
     また,飽和計画の場合,常法での解析は困難であるが,要因効果の平方和の自由度がすべて 2 以上のままである特別な場合を除き,自由度 1 の平方和が増えるにつれ,誤差の自由度が増えていく本法では,分散分析が可能となる.
     本研究の方法を適用すれば,3 水準以上の処理を含む実験の実務への適用を支援することができる.実務家にとって,検出力の高い解析法の利得は大きい.
