The Effects of Physiotherapy Programmes, Aided by Virtual Reality Solutions, on Balance in Older Women: A Randomised Controlled Trial

Background: Modern technologies are being applied to maintain and improve the functional performance of older adults. Fully immersive virtual reality (VR) combined with a scope of dual-task (DT) activities may effectively complement conventional physiotherapy programmes for seniors. The study aimed to compare the effectiveness of a fully immersive virtual reality (VR) environment combined with a scope of dual-task activities regarding balance in older women. Methods: Eighty women were recruited to the study protocol and, following randomisation, allocated to two equally sized groups, one pursuing conventional OTAGO exercises, the other one the VR-solutions-aided exercise programme combined with a scope of DT activities. Physiotherapy sessions spanned 6 weeks, each one lasting 60 min, three times a week, in both groups. Results: Homogeneity analysis of both study groups indicated no statistically significant differences at the first measurement point. After the intervention, both study groups achieved significantly improved scores on all tests. The VR + DT group obtained better results in dual-task gait and single-leg standing, whereas the greatest difference was observed during SLS CL (1.52 s vs. 2.33 s—difference 0.81 s 53.2% change, p = 0.001). The OTAGO group performed better in the TUG single-task gait (11.35 s vs. 12.60 s, p < 0.001) and in the Berg balance scale. Conclusions: The VR + DT training is effective in improving individual balance as well as in reducing fall risks. VR-assisted physiotherapy should complement conventional physiotherapy programmes (e.g., OTAGO). The benefits of applying VR solutions indicate that older women might well use this form of activity regularly under the guidance of a therapist or a family member.

Factors that influence the uptake of virtual care solutions in Australian primary care practice: a systematic scoping review.

Uptake of virtual care solutions in primary care settings has increased exponentially, and current evidence suggests high patient satisfaction but mixed clinician views. This paper aimed to identify factors influencing its' implementation to support delivery to the right patient, in the right clinical context, at the right time. Further, this paper evaluates how the updated Consolidated Framework for Implementation Research (CFIR) can be used to assess these factors that contribute to the uptake of virtual care innovations. This systematic scoping review identified empirical research on factors influencing the uptake of virtual care solutions in the Australian primary care setting. Searches were undertaken in Embase, PubMed, Scopus, and Web of Science. The CFIR was used to code factors influencing the implementation of virtual care solutions. Inductive coding was used to generate new constructs where no appropriate CFIR construct could be identified. Fourteen eligible studies were identified as eligible for inclusion. Five common influencing factors were identified. Three are from the existing CFIR framework, and two are newly developed constructs. CFIR constructs included innovation relative advantage, capability, and IT infrastructure. New constructs included accessibility and suitability. A further six new constructs were identified (trust, privacy, governance, unintended consequences, preference, and choice) but these were not prominently mentioned. Common factors influence virtual care uptake in Australian primary care. The CFIR assisted in conceptualizing these but was not sufficient for capturing factors unique to virtual care. Newly developed constructs are noted to be of importance in the literature, but further research is needed to understand whether they are applicable in multiple contexts. http://links.lww.com/IJEBH/A286.

Virtualization and energy management optimization of high speed computer network data centers based on optical switching and network technology

With the development of cloud computing and big data technology, the scale and complexity of data centers are increasing, and the thermal energy consumption management of computer processors can effectively improve the energy efficiency of data centers and reduce operating costs. Therefore, this study discusses the application of high-speed computer network architecture based on optical switching and network technology in data center virtualization. By constructing a high-speed computer network model based on optical switching technology, virtualization technology is used to dynamically schedule and manage resources, combined with real-time monitoring system, and the energy consumption data of the processor is collected. Using the data analysis method, the energy consumption performance under different load conditions is evaluated and the optimization strategy is proposed. The experimental results show that the network architecture using optical switching technology significantly reduces the latency of data center and improves the resource utilization. In the thermal management of the processor, dynamic resource scheduling successfully reduces the energy consumption and effectively maintains the stability and performance of the system. As a result, data center virtualization solutions based on optical switching and networking technologies can significantly optimize the power management of computer processors and improve overall energy efficiency.

The accounting of virtual robots

Purpose: The aim of the article is to present the principles and methods of measuring the activity of virtual robots. We link the identified metrics to analogies of perceiving a bot as a machine, an automated process, or a digital employee. The latest phenomenon of the anthropomorphization of bots receives special attention.Methodology/approach: We used text analysis of technical and marketing documentation as the research method. We conducted the analysis as a case study using the software of a leading international RPA (Robotic Process Automation) provider.Findings: The results lead to the following conclusions: accounting using bots is multidimensional, embedded in technology, and carried out in real time. The virtual robot accounting solutions avoid the analogy of virtual employees; measurement covers both bots and operators, and the representation of activities is incomplete and distorted.Research limitations/implications: The research was focused on subjective recommendations of the RPA technology provider, taking into account their marketing goals. Originality/value: The research shows that embedded measurement technology automates raw data collection and enables real-time accounting for both bots and their operators. It thus contributes to the development of hybrid accounting. Simultaneously, this technology has a constraining effect, distorting measurement and redefining well-known and well-established effectiveness metrics.

These findings offer valuable insights for industry practitioners and provide a strategic framework to enhance user engagement and retention in VR events. Moreover, this research lays the groundwork for future explorations into VR efficiency in the broader context of virtual events.

Virtualization of Service Consumer Behavior in Poland – A Post-Pandemic Perspective

ABSTRACT This article explores the impact of the COVID-19 pandemic on the virtualization of consumer behaviors in the Polish service sector, emphasizing shifts in service delivery mechanisms. The pandemic acted as a catalyst, accelerating the adoption of virtual solutions across various sectors including tourism, gastronomy, culture, education, and healthcare, as necessitated by social distancing and other restrictive measures. The article first outlines the integration of digital solutions into various service sectors, focusing on the impact of these technologies on consumer behaviors and service delivery. Next, utilizing an online survey conducted in November 2022 with a sample of 1,100 respondents, whose socio-demographic profile corresponds with that of Polish internet users (Ariadna panel), the study examines consumer perceptions and the effectiveness of digital transformations during the pandemic. The findings indicate a high appreciation among Polish consumers for virtual solutions that improved access to and use of services during restrictive periods. However, the continuation of these virtual engagements post-pandemic appears selective, with significant inclination towards solutions in administrative, food delivery, and telemedical services, while long-term engagement in virtual cultural services is less favored. This study underscores the dual role of necessity and technological advancement in reshaping consumer interactions with service sectors, suggesting a sustained yet selective future for virtual service consumption post-pandemic.

Feedback to national medical commission regarding aadhar-enabled biometric attendance system at medical colleges in India.

Teachers are the backbone of any country, the pillars upon which all aspirations and dreams converge, if we paraphrase 11th President of India, Dr A P J Abdul Kalam,. A teacher of a Medical college has immense potential to shape the foundation and basic wisdom/ technical skills of a young student and resident. So, teachers' absence makes the learners bereft of these gifts- making them vulnerable to construct poor reasoning and judging clinical scenarios inappropriately: deriving incorrect or false interpretation from a given case presentation. For this reason, when the National Medical Commission (NMC) comes up and pushes for an idea ensuring physical presence of workforce at their respective workplaces, everyone should welcome the move. Nevertheless, like every fixture the virtual solution has its unique challenges, requiring nuances for proper assessment, demands reasoned and detailed dissection of actual ground -level situation; hence, I want the regulatory body to tweak the attendance -system to make it suitable for diverse atmosphere, varying working -conditions and rapidly -changing environment. Such formulation should have two- way communication channels between man (and woman) power as well as their regulators. Only then fine -tuning may be expected to be achieved to derive the maximum benefit while reducing chances of error/ omission/ glitch/ incompleteness and fault.

Elevating Security in Migration: An Enhanced Trusted Execution Environment-Based Generic Virtual Remote Attestation Scheme

Cloud computing, as the most widely applied and prominent domain of distributed systems, has brought numerous advantages to users, including high resource sharing efficiency, strong availability, and excellent scalability. However, the complexity of cloud computing environments also introduces various risks and challenges. In the current landscape with numerous cloud service providers and diverse hardware configurations in cloud environments, addressing challenges such as establishing trust chains, achieving general-purpose virtual remote attestation, and ensuring secure virtual machine migration becomes a crucial issue that traditional remote attestation architectures cannot adequately handle. Confronted with these issues in a heterogeneous multi-cloud environment, we present a targeted solution—a secure migration-enabled generic virtual remote attestation architecture based on improved TEE. We introduce a hardware trusted module to establish and bind with a Virtual Root of Trust (VRoT), addressing the challenge of trust chain establishment. Simultaneously, our architecture utilizes the VRoT within TEE to realize a general-purpose virtual remote attestation solution across heterogeneous hardware configurations. Furthermore, we design a controller deployed in the trusted domain to verify migration conditions, facilitate key exchange, and manage the migration process, ensuring the security and integrity of virtual machine migration. Lastly, we conduct rigorous experiments to measure the overhead and performance of our proposed remote attestation scheme and virtual machine secure migration process. The results unequivocally demonstrate that our architecture provides better generality and migration security with only marginal overhead compared to other traditional remote attestation solutions.

A Parallel Compression Pipeline for Improving GPU Virtualization Data Transfers.

GPUs are commonly used to accelerate the execution of applications in domains such as deep learning. Deep learning applications are applied to an increasing variety of scenarios, with edge computing being one of them. However, edge devices present severe computing power and energy limitations. In this context, the use of remote GPU virtualization solutions is an efficient way to address these concerns. Nevertheless, the limited network bandwidth might be an issue. This limitation can be alleviated by leveraging on-the-fly compression within the communication layer of remote GPU virtualization solutions. In this way, data exchanged with the remote GPU is transparently compressed before being transmitted, thus increasing network bandwidth in practice. In this paper, we present the implementation of a parallel compression pipeline designed to be used within remote GPU virtualization solutions. A thorough performance analysis shows that network bandwidth can be increased by a factor of up to 2×.

Comparative Analysis of Non-Pneumatic Tire Spoke Designs for Off-Road Applications: A Smoothed Particle Hydrodynamics Perspective

This study explores the development of a terramechanics-based model for non-pneumatic tire–terrain interaction, focusing on different spoke designs. The research investigates how four spoke shapes (honeycomb, modified honeycomb, re-entrant honeycomb, and straight spokes) affect non-pneumatic tire performance in off-road conditions. Using the finite element method (FEM) to model non-pneumatic tires, and smoothed-particle hydrodynamics (SPH) to model dry, loose soil, simulations were conducted to replicate real-world loading conditions. This study utilizes virtual environment solution finite element analysis software to examine the interaction between a non-pneumatic tire and dry, loose soil, with a focus on calculating longitudinal and vertical forces. These forces play a pivotal role in determining the motion resistance coefficient. The results show distinct variations in the motion-resistance coefficients among the spoke designs on dry, loose soil. This analysis helps to identify the spoke configurations that optimize energy efficiency and fuel consumption. By comparing and evaluating the four spoke designs, this study shows the effect of spoke design on tire motion resistance. This study concluded that the modified honeycomb spoke design is the most stable and the least sensitive to operating conditions.

Designing Virtual Coaching Solutions

Especially older persons are prone to disabilities and chronic diseases. These chronic conditions pose a worldwide challenge, leading to deteriorating health, economic strain, loss of life, and a decline in the quality of life (QoL). Therefore, healthcare institutions seek to enhance their strategies for disease prevention and management to uphold the well-being of the community. This leads to the need to regain independence and improve QoL to properly rehabilitate the patients. Virtual Coaches (VCs) in the form of Embodied Conversational Agents are seen as a relevant digital intervention to support the continuity of care. The paper at hand reports on a Design Science Research project about implementing a VC solution to support older patients' home rehabilitation. The study underpins four pivotal design principles: Adaptivity, Coaching Strategy, Multi-user Interface, and Sustainable Infrastructure. The final artifact was tested with 80 patients which were supported in continuing their inpatient rehabilitation at home by using a VC. The evaluation shows both positive results for usability and acceptance of the intervention for four different use cases and a positive impact on the QoL. Given the comprehensive clinical evaluation, the system represents a safe and appealing solution for ensuring the continuity of medical rehabilitation care and the access to personalized cognitive and motor function treatments.

Improving balance using augmented visual orientation cues: a proof of concept

Falls are a major health concern. Existing augmented reality (AR) and virtual reality solutions for fall prevention aim to improve balance in dedicated training sessions. We propose a novel AR prototype as an assistive wearable device to improve balance and prevent falls in daily life. We use a custom head-mounted display toolkit to present augmented visual orientation cues in the peripheral field of view. The cues provide a continuous space-stationary visual reference frame for balance control using the user’s tracked head position. In a proof of concept study, users performed a series of balance trials to test the effect of the displayed visual cues on body sway. Our results showed that body sway can be reduced with our device, indicating improved balance. We also showed that superimposed movements of the visual reference in forward-backward or sideways directions induce respective sway responses. This indicates a direction-specific balance integration of the displayed cues. Based on our findings, we conclude that artificially generated visual orientation cues using AR can improve balance and could possibly reduce fall risk.
