This study focuses on an at-home wrist rehabilitation system aimed at achieving a situation where a home-stay patient can receive rehabilitation from a therapist in a clinic. In a former report, a pneumatic driven at-home wrist rehabilitation system, which could be used for passive exercise, was developed. Using the same system that was developed, this paper discusses the realization of rehabilitation by active exercise based on the wrist characteristics obtained in passive exercise. Firstly, game-based active-resistive exercise is proposed. Then game-based active assistive exercise using the wrist characteristics obtained in passive exercise to set up the assist torque is proposed. From the experimental results in the clinic, the validity of rehabilitation by active exercises developed in this paper is verified. From the above, it is clarified that both passive and active exercise could be carried on by the at-home wrist rehabilitation system developed in this research.

This study focuses on the at-home wrist rehabilitation system aiming to achieve the situation where home-stay patients can accept rehabilitation from therapist in clinic. As the first stage, this paper discusses the development of the wrist rehabilitation by remote passive exercise for stroke patients. Firstly, based on the dynamic model of passive exercise, rehabilitation by remote passive exercise is proposed. Secondly, pneumatic pseudo-therapist which can realize the therapist's rehabilitation actions and pneumatic pseudo-patient which can realize the patient's resistance are designed and fabricated. Finally, based on the experimental result in clinic, the validity of the rehabilitation system developed in this paper is verified.

【背景】透析患者において睡眠障害の訴えの頻度は高いものの,その実態については十分に解明されていない.【目的・方法】透析患者の睡眠評価のため,維持血液透析患者41名に自記式ピッツバーグ睡眠質問票(PSQI)による主観的評価とアクチグラフによる客観的評価を行った.【結果】PSQIでは,睡眠薬群では全例,睡眠薬なし群でも40%が睡眠障害ありと判定された.アクチグラフでは,入眠障害・中途覚醒の指標が不良で,総睡眠時間が短縮していた.睡眠薬なし群は,睡眠薬群より中途覚醒が多く,これは日中の覚醒困難の訴えと関連していた.【考察】健常人の報告例と比較し,主観では中途覚醒が頻回で,客観には入眠障害を示し中途覚醒も頻回であった.【結論】透析患者の睡眠は不良であり,睡眠薬の服用は中途覚醒に一部奏効しているが,入眠障害は残っている.睡眠薬なし群では入眠障害の訴えが表れにくく,日中覚醒困難を伴う中途覚醒とともに問題となる.

In conventional bill money recognition machines, we develop the recognition algorithm according to the transaction speed and diffierence of various specifications. However, development of the algorithm for the recognition has been based on the trial and error method. Many researchers have reported that neural networks are suitable for pattern recognition because of the ability of selforganization, parallel processing, and generalization. In this paper, we present a new bill money recognition method with neural network and show the effectiveness of the present algorithm compared with the conventional method by discrimination functions. Furthermore, we transform bill money data by FFT into frequency domain to reduce influence of the noise due to conveyed fluctuation. Then we adopt these Fourier coefficients or its amplitudes as input of the neural network. We show that the ability of recognition can be evaluated in detail by introducing a new measure of reliability.

低濃度NMP溶液からキャスト製膜したポリアニリン膜を硫酸水溶液に浸漬し, ドープしてその導電率を求めた.硫酸水溶液の濃度の増加に伴い導電率は単調に増大し, pH=0.8以上で飽和に達した.重量変化, X線回折スペクトルによる構造変化から硫酸濃度がpH=2を超えると分子鎖間が拡大し硫酸イオンが導入され新たな結晶化が進み導電率が大きく増加することがわかった.
