The global cloud computing infrastructure market, valued at $280 billion annually and dominated by three hyperscale providers (AWS, Google Cloud, Microsoft Azure controlling 65% market share), operates on an economies-of-scale model requiring massive capital expenditure ($1.5-2B per data center). This paper presents the first comprehensive empirical and theoretical analysis of Decentralized Physical Infrastructure Networks (DePIN) as a viable alternative, introducing novel frameworks including the Infrastructure Entropy Model (IEM) and Byzantine Efficiency Ratio (BER). Through 60 days of production testnet operation across 1,200 nodes in 35 countries executing 15 million tasks, we demonstrate that DePIN achieves 60-80% cost reduction for edge computing workloads while maintaining competitive median latency (42ms DePX vs. 45ms AWS Lambda@Edge, p=0.03). However, Byzantine fault tolerance imposes a measured 6.74× overhead, limiting DePIN viability to workloads tolerating eventual consistency and accepting 99.2% availability versus 99.9%+ enterprise SLAs. We prove the existence of sustainable tokeneconomic equilibrium under demand-driven issuance models, validated through 10,000 Monte Carlo simulations showing 82% network survival probability when demand growth exceeds 12% monthly. Our cost analysis reveals DePIN achieves competitive advantage specifically when centralized providers must replicate infrastructure geographically (multiregion deployments), where DePIN's distributed architecture provides coverage organically at no incremental cost. Market analysis identifies a $73-100B total addressable market by 2030 (26-36% of cloud infrastructure), concentrated in edge compute, content delivery, AI inference, and IoT aggregation-workloads where geographic distribution is inherently valuable and strong consistency is not required. This work provides the first rigorous economic and technical framework for evaluating DePIN viability, establishing that decentralized infrastructure occupies a sustainable niche complementing rather than replacing centralized clouds, with optimal adoption strategy being hybrid architecture allocating 70% of workloads to DePIN (cost-sensitive, edge-distributed) while maintaining 30% on centralized clouds (mission-critical, strong consistency).

Objective: This study aimed to determine the level of student satisfaction with using the AIpowered Socrative platform for providing quality assessment and instant feedback on the anatomical information of bones and joints, and its role in guiding correct technical performance in tennis. Methodology: The experiment was conducted during lectures in the second semester of 2025. A QR code for the Socrative website was displayed via a projector, allowing students to access it on their mobile phones. The lecturer controlled the timing of the questions to align with the flow of the lecture. Questions were presented on the students' phones, with their answers receiving instant feedback. Simultaneously, each student's results were displayed by name on the lecturer's screen. Results: The findings revealed exceptionally high levels of satisfaction: ease of use was rated between 86% and 98%, and the quality of assessment and feedback was rated between 90% and 97%. The platform was also highly effective in enhancing interaction and understanding of complex anatomical concepts (over 96%). Furthermore, the results demonstrated the students' ability to effectively apply this knowledge to improve their technical performance in tennis (94%) and to correct their conceptual understanding of the body's function as an integrated system (97%). Recommendations: The study recommends the official adoption of the Socrative platform in faculties of physical education, the provision of training for faculty members on its use, and the encouragement of future research to link theoretical content with practical application.

This study aimed to investigate the impact of the flipped classroom approach on the cognitive achievement of physical education students in a health education course, compared to traditional instruction. Employing an experimental design, second-year students were divided into two groups: a flipped classroom group and a traditional instruction group. The flipped classroom strategy was implemented with the first group, while the second group received conventional lectures. Cognitive achievement was assessed through five electronic examinations. The findings revealed statistically significant differences between the two groups, favoring the flipped classroom approach in all assessments. The study concluded that the flipped classroom is an effective pedagogical strategy for enhancing cognitive achievement and recommended its wider implementation across various academic levels and subjects within the faculty.
