Abstract

This study analyzed the influence of educational technology use on university learning within the framework of digital transformation in higher education. A quantitative, non-experimental, cross-sectional, correlational-explanatory design was employed. The sample consisted of 480 undergraduate students from five academic areas. Data were collected through a structured questionnaire with Likert-type scales assessing educational technology use and university learning. The instrument showed high internal consistency (α = 0.93). Descriptive, correlational, comparative, and regression analyses were conducted. The findings revealed a positive and statistically significant relationship between educational technology use and university learning (r = 0.64, p < .01). Students with high levels of educational technology use reported significantly higher levels of learning than those with medium and low use, F(2,477) = 61.37, p < .001. Multiple linear regression showed that educational technology use was the strongest predictor of university learning (β = 0.548, p < .001), explaining 46.7% of the variance in the dependent variable. The pedagogical purpose of technology use and digital interaction showed stronger associations with learning than simple frequency of use. The results suggest that digital transformation contributes positively to university learning when technology is integrated with clear pedagogical purposes, active engagement, and meaningful academic interaction. The study concludes that educational technologies are not inherently transformative; their impact depends on how they are used, the quality of instructional design, and the institutional conditions that support digital learning.

Abstract

Atherosclerotic disease significantly impacts patients with type 2 diabetes, who often present with recalcitrant peripheral ulcers. The angiosome model of the foot presents an opportunity to perform direct angiosome-targeted endovascular interventions to maximise both wound healing and limb salvage. A systematic review was performed, with 17 studies included in the final review. Below-the-knee endovascular interventions present significant technical challenges, with technical success depending on the length of lesion being treated and the number of angiosomes that require treatment. Wound healing was significantly improved with direct angiosome-targeted angioplasty, as was limb salvage, with a significant increase in survival without major amputation. Indirect angioplasty, where the intervention is applied to collateral vessels to the angiosomes, yielded similar results to direct angiosome-targeted angioplasty. Applying the angiosome model of the foot in direct angiosome-targeted angioplasty improves outcomes for patients with recalcitrant diabetic foot ulcers in terms of primary wound healing, mean time for complete wound healing and major amputation-free survival.
