Effects of Healthcare Technologies on the Promotion of Physical Activities in Older Persons: A Systematic Review.

This study aimed to explore the effects of health technologies on the promotion of health through physical activities of older persons. Following PRISMA guidelines, a systematic review of relevant articles published prior to 2020 was conducted from selected indices such as COCHRANE, PubMed, Science Direct, Proquest, including the use of hand search procedure. Twenty-seven articles were analyzed with significant findings influential to older people nursing: types of health technologies used for promoting physical activity; effects of technology use in promoting physical activity of older person care; and aspects that need to be considered in technology use among older persons. Characteristics of technologies were accuracy, usefulness, reliability, comfort, safety, and relevancy. Most technologies promoting physical activities for older people were wearable technologies that use artificial intelligence. Altogether, these technologies influenced overall healthcare behaviors of older persons. With healthcare technology efficiencies, proficiencies, and dependencies, technology-based healthcare have served older people well. Most technologies for older people care, such as wearables, reliably produce characteristics enhancing dependency and accuracy of bio-behavioral information influencing physical activities of older persons. Health technologies foster the values of physical activities among older persons thereby promoting healthy living.

Living alone and using social media technologies: The experience of Filipino older adults during the COVID-19 pandemic.

Prolonged implementation of lockdowns during the coronavirus disease 2019 (COVID-19) pandemic has resulted in older adults living alone in social isolation. The purpose of the study was to describe the meaning of the experience of Filipino older adults, who are living alone and using social media technologies during the COVID-19 pandemic. Eight participants who met the inclusion criteria were interviewed using the snowball selection technique. Transcribed interviews were read while also listening to the recorded interviews and highlighting significant words, phrases, and statements. An iterative process of analysis using van Manen's phenomenological approach identified thematic structures and categories revealing life-worlds of corporeality, relationality, temporality, spatiality, and materiality. The five general essences of flourishing, communicating, struggling, journeying and empowering, described the meaning of living alone and using social media technologies among older adults during the pandemic. The experience was expressed as "flourishing despite struggling to communicate, while journeying and empowering oneself and others." Older adults in isolation struggled to communicate with others however, with social technologies opportunities were opened for them in securing needed food, safety and security, maintaining their health, and their social connectedness. Despite the physical isolation and living arrangements during the pandemic, the use of social media technologies sustained older persons' well-being.

The Contagion of Pneumonia in Older Persons: An Application of the Bass Diffusion Model.

This aims to provide an understanding of the spread of pneumonia through analysis of the interaction between infected and potentially infected. Data from 2010 to 2018 on Pneumonia morbidity among older persons age 65 and above was extracted from the Department of Health Field Health Service Information System (FHSIS) annual reports. The data were used to represent the cumulative adopters by fitting them to the Bass diffusion model using the Bass Forecasting Spreadsheet. The number of new adopters was graphed to forecast the diffusion of Pneumonia. The number of cases is expected to increase. The adoption rate in 2024 will be around 45% of the current population. Morbidity of pneumonia is expected to peak in the year 2200, 190 years after the first data. The use of the model provided an insight into the cumulative nature of pneumonia infection due to the interaction between infected and the potentially infected.

Extrusion-Based 3D Printing of Hierarchically Porous Advanced Battery Electrodes.

A highly porous 2D nanomaterial, holey graphene oxide (hGO), is synthesized directly from holey graphene powder and employed to create an aqueous 3D printable ink without the use of additives or binders. Stable dispersions of hydrophilic hGO sheets in water (≈100 mg mL-1 ) can be readily achieved. The shear-thinning behavior of the aqueous hGO ink enables extrusion-based printing of fine filaments into complex 3D architectures, such as stacked mesh structures, on arbitrary substrates. The freestanding 3D printed hGO meshes exhibit trimodal porosity: nanoscale (4-25 nm through-holes on hGO sheets), microscale (tens of micrometer-sized pores introduced by lyophilization), and macroscale (<500 µm square pores of the mesh design), which are advantageous for high-performance energy storage devices that rely on interfacial reactions to promote full active-site utilization. To elucidate the benefit of (nano)porosity and structurally conscious designs, the additive-free architectures are demonstrated as the first 3D printed lithium-oxygen (Li-O2 ) cathodes and characterized alongside 3D printed GO-based materials without nanoporosity as well as nanoporous 2D vacuum filtrated films. The results indicate the synergistic effect between 2D nanomaterials, hierarchical porosity, and overall structural design, as well as the promise of a freeform generation of high-energy-density battery systems.
