Abstract: A composite component includes an Si base layer that has first and second main surfaces that are opposite to each other, a rerouting layer on the first main surface, a through-silicon via that is electrically connected to the rerouting layer, and that extends through the Si base layer, and an electronic component layer on the second main surface of the Si base layer, and that includes electronic components each including an electronic component body and a component electrode on the electronic component body. The component electrode is connected to the through-silicon via. One or more of the electronic components have a curved shape that is curved to protrude in a mount direction in a cross-sectional view. A mount surface of the composite component corresponds to the curved shape in a cross-sectional view, and includes one or more first curved surfaces that are curved to protrude in the mount direction.

Abstract: A relationship index value computation unit 100A that extracts n words from m texts representing contents of free conversations conducted by m patients whose severity of dementia is known, and computes a relationship index value reflecting a relationship between the m texts and the n words, a prediction model generation unit 14A that generates a prediction model for predicting severity of dementia based on a text index value group including n relationship index values for one text, and a dementia prediction unit 21A that predicts severity of dementia of a patient from a text subjected to prediction by applying the relationship index value computed by the relationship index value computation unit 100A from a text input by a prediction data input unit 20 to a prediction model are included, and severity of dementia can be predicted without performing a mini-mental state examination.
