Outline of Final Research Achievements	The purpose of this study was to add a function to detect high-risk conditions of foot ulcers to a preventive support system for diabetic foot ulcers using thermography, and to examine its usefulness. We investigated the ease of use of the improved device with 10 healthy people, and it was 7.5 out of 10 points. In the home environment, we obtained the same plantar thermography pattern as the previous research conducted in the hospital, suggesting the feasibility of this device in the home environment. We created an algorithm to identify local skin temperature rises on thermographic images using the segmentation method, and as a result of examining 64 images of healthy volunteer's data, including 4 images of skin temperature rises, it was able to identify 3 images. In the future, it is necessary to verify the function of detecting high-risk conditions for foot ulcers using clinical images of foot ulcers.

Academic Significance and Societal Importance of the Research Achievements	潰瘍化の指標となるサーモグラフィを用いて、自身の足底の皮膚温を観察できるデバイスを改良し、そのユーザビリティと家庭環境における実現可能性を示したことは、サーモグラフィを用いた糖尿病足潰瘍予防支援システムを完成させるステップとなる。今後、臨床での検証を行い、システムが完成すれば、特に仕事などで忙しく頻回の受診が困難な壮年期の糖尿病患者、専門病院への受診が困難な在宅医療を受けている高齢の糖尿病患者、将来的には、糖尿病患者数が増加しているアジア諸国の糖尿病足潰瘍予防に貢献することが期待される。
