There is growing academic and practical interest in mental health and wellbeing care systems for elite athletes, including rugby players. Concerns about career transition and its maladaptation are one of the athlete-related factors for mental health problems. The Player Development Program (PDP), which has been implemented mainly in New Zealand, Australia and Europe etc., is a system that supports elite athletes from multiple perspectives while they are active players. According to international practice reports and papers, PDP can also contribute to improving performance. We documented the practice and the feedback of the PDP conducted by the Japan Rugby Football Playersʼ Association (JRPA) as a “Research Note”. In the current practice, from December 2020 to October 2021, we matched 11 active Japanese rugby players and 11 Player Development managers (PDM) in a one-to-one setting to provide an opportunity to speak online once a month. During the period, 10 out of 11 pairs completed the trial. From the feedback after the 10-month practice, the satisfaction of the players was high, and the PDMs answered that it was necessary for active players. Future challenges for promoting the PDP in the Japanese sports society are the specification of PDP in Japan, securing financial resources for the operation, and securing PDM human resources.

Sand erosion is a phenomenon in which the collision of solid particles erodes a material surface. The rate of sand erosion is higher in carbon fiber reinforced plastics (CFRP) than in metallic materials. Therefore, CFRP requires a light and protective coating material. Herein, to improve the erosion resistance of CFRP, five polyurethane coated CFRPs with different glass transition temperatures were investigated at elevated temperatures, and a prediction formula of the erosion rate at the elevated temperatures was established. Furthermore, computational fluid dynamics was used to predict the surface temperature and erosion rate of fan exit guide vane (FEGV) when polyurethane coating was applied, and the coating thickness for FEGV in the erosion environment was estimated based on these predictions.

ニューロバイオニクスにおける血流増加作用を骨盤内臓器の血流を測定することにより動物実験においてあきらかにした。血流増加作用は刺激直後から速やかにみとめられた。骨盤内臓器において、膀胱、陰茎、前立腺のいずれにおいても血流は増加した。ニューロバイオニクスの作用機序のひとつは虚血改善作用であることが示唆される。臨床的検討においては、電ニューロバイオニクスにより大脳皮質の一次感覚野付近に反応を認め、中枢神経系に対する反応が認められ中枢神経系の関与も示唆される。
