Design of Occupational Therapy Interventions for Middle-Aged and Elderly Family Caregivers.

This study aimed to develop an interactive app for occupational therapy interventions for middle-aged and elderly family caregivers by integrating life review and narrative therapy. The results indicated that the interventions improved the mood of individuals, but the improvement in the quality of life was less significant due to the multiple facets of life. The interface design of the interactive app had good operating characteristics and was above average in terms of learnability and usability. Overall, the intervention program positively improved participants' psychological aspect, which was in line with the purpose of the life review. Thus, a focus group put forward specific suggestions on the contextual construction of life review, the intelligent development of guiding questions, scenario simulation, and the introduction of creative collaboration functions, which could be used as a reference for subsequent content adjustment and interface design.

Reusable macroporous photonic crystal-based ethanol vapor detectors by doctor blade coating.

This research reports the development of sensitive and reversible vapor detection by using three-dimensional macroporous photonic crystals. A scalable and roll-to-roll compatible doctor blade coating technology is utilized to fabricate flexible macroporous poly(ethoxylated trimethylolpropane triacrylate) (PETPTA) films with hexagonal close-packed pores which are interconnected. The pores are then coated with a layer of poly(2-hydroxyethyl methacrylate) (PHEMA) to create macroporous PHEMA/PETPTA films. The condensation of vapors in the PHEMA coated macroporous films leads to the increase of both the PHEMA swelling degree and the effective refractive index of the diffractive medium, resulting in the red-shift and amplitude reduction of the optical stop bands. The optical measurements reveal that the diffraction from the as-prepared macroporous photonic crystals sensitively monitors the vapor pressure of ethanol since the PHEMA layer displays a great volume dependence on ethanol due to a decreased Flory-Huggins mixing parameter. The dependence of the diffraction wavelength on vapor pressure and the reproducibility of vapor sensing have also been investigated in this study.
