Chemical warfare agents (CWA) continue to present a threat to civilian populations and military personnel in operational areas all over the world. Reliable measurements of CWAs are critical to contamination detection, avoidance, and remediation. The current deployed systems in United States and foreign militaries, as well as those in the private sector offer accurate detection of CWAs, but are still limited by size, portability and fabrication cost. Herein, we report a chemiresistive CWA sensor using single-walled carbon nanotubes (SWCNTs) wrapped with poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives. We demonstrate that a pendant hexafluoroisopropanol group on the polymer that enhances sensitivity to a nerve agent mimic, dimethyl methylphosphonate, in both nitrogen and air environments to concentrations as low as 5 ppm and 11 ppm, respectively. Additionally, these PEDOT/SWCNT derivative sensor systems experience negligible device performance over the course of two weeks under ambient conditions.

We investigated changes in the Activities of Daily Living (ADL) of stroke patients in a convalescent rehabilitation ward and a general ward using a Functional Independent Measure (FIM). The subjects were 109 patients hospitalized for rehabilitation purposes at the Oyamada Memorial Spa Hospital. The change in FIM at the time of hospitalization and that at 1 week later was investigated in 81 patients in the convalescent rehabilitation group (CRG) and 28 patients in the control group (CG). In addition, the CRG was investigated again after one month. Intensive rehabilitation service based on ADL and worksheets was introduced in the CRG. On the other hand, these were not introduced in the CG. The total score of FIM increased significantly (p<0.01) in the first week after hospitalization in both groups. The FIM-gain after one week in the CRG was high. With regard to each item, a significant improvement was observed in patients' motor skills while eating, grooming, bathing, dressing the upper body, dressing the lower body, toilet, bladder management, transfer bed/chair, toilet and tub, and walking/wheelchair (11/13). Multiple regressions were used to assess the relationships between FIM-gain (one week, one month), age, rehabilitation intensity and other predictive variables. Better rehabilitation outcomes were observed in patients with lower level of dementia and high rehabilitation intensity. It was thought that planned rehabilitation based on ADL was effective in the CRG, and it was suggested that the CRG's system is effective in the rehabilitation of stroke patients.
