An advice instructed by a professional trainer is one of the important roles for skill learning of a trainee. Video movie recording is also an effective tool to recognize skill level visually. However, the trainee might misunderstand the advice because of ambiguity of natural language. Moreover, it is quite difficult to recognize an extremely quick and small action with the video movie. As a practical solution to overcome these problems, this paper reports quantitative action data collection, data analysis, and an example of training.

In deciding which IoT technologies should be introduced in the maritime industry, it is important to quantitatively compare their diverse functions. In this research, an evaluation method using a parametric ship operation simulator is proposed. The simulator consists of three models, shipping, loading and docking, with the shipper's QCD (safety, economy and delivery reliability) as evaluation criteria. The effect of introducing IoT technologies is evaluated by changing input parameter value. As a case study, evaluation of various kinds of actual IoT technologies was conducted. The Result showed that the proposed method can quantitatively compare each IoT technology considering technology's maturity levels.

Many IT venders need to adopt a mixture of waterfall and agile development, which is called mixed agile. In order to manage the mixed agile projects, project managers have to design the agility of the development process considering rework caused by requirement change. This study proposes a design method for mixed agile project. To be concrete, a new model to represent the agility for simulation of mixed agile process is proposed and a simulator which evaluates the mixed agile project based on the agility model is developed. A case study shows a demonstration of project design using the proposed method. The sensitivity analysis in changing the product 's structure and the process's agility is conducted and the result shows the usefulness and availability of the proposed method.
