Waste-printed circuit boards (WPCBs) are recycled in nonferrous metal smelters to recover valuable metals. Workers visually determine the similarity between images of previously handled WPCBs and images of substrates to be measured for their valuable metal content and classify the substrates to so that appropriate processing methods can be selected. In particular, groups of substrates of multiple types (mixed WPCBs) are more difficult for workers to process. Therefore, in this study, we propose a method to evaluate different types of substrates using segmented images of mixed WPCBs. Our results show that the proposed approach was able to classify substrates appearing in segmented images well.

With the recent emergence of a super-aging society, extending the healthy life expectancy of older adults has become increasingly important. Dementia has been reported to hinder the extension of healthy life expectancy. Electronic sports (eSports) have recently attracted wide attention to prevent dementia. People experience various emotions while playing eSports. The quantification of these emotions indicates the extent to which they enjoy playing eSports. This indicator can be used to evaluate eSports activities. We propose a method to estimate when emotions occur while playing eSports with the aim of creating a quantitative index to determine people's emotions while playing eSports. Consequently, we determined the possibility of estimating emotional arousal intervals by examining the changes in the saturation of the cheeks using machine learning.
