Background: In recent years, Virtual Reality (VR) has emerged as a promising tool to improve the well-being and functional capabilities of older adults. Although VR applications have shown positive results, their impact on user experience and therapeutic outcomes still needs to be evaluated. Objective: This scoping review aims to analyze existing studies on VR use in older adults with neurodegenerative disorders, focusing on the factors that influence usability, satisfaction, and immersion, as well as the effects on emotional and cognitive well-being. Materials and Methods: Empirical studies in English were included on VR applications applied to older adults with cognitive impairment without study design restrictions. The search was conducted in IEEE Xplore, PubMed, Scopus, and Web of Science, identifying a total of 650 initial results. After screening, 14 studies met the inclusion criteria. Results: Immersive VR tends to generate a greater sense of presence, which contributes to improving emotional well-being and reducing neuropsychiatric symptoms, such as apathy and depression. However, its impact on cognitive functions, including memory and executive skills, varied depending on the level of immersion and participant characteristics. Despite these positive findings, significant heterogeneity was evident in study designs, measurement instruments, and user experience indicators. Conclusion: Virtual environments have great potential as a therapeutic tool for older adults, but their success depends on the personalization of applications and the adaptation of technology to the specific needs of this population. Future research should focus on developing standardized protocols, incorporating adaptive technologies such as artificial intelligence, and evaluating the long-term effects of VR to maximize its benefits and minimize its risks.

In recent years, robotics has transformed various industrial processes but has also influenced teaching methodologies. Although there are literature reviews on its application in professional training, many are outdated or lack a current focus on its impact in higher education. Addressing this gap, the present mini review examines the impact, challenges, and opportunities of this technology in the university setting. To this end, a search was conducted in the PubMed, Scopus, IEEE Xplore, APA PsycNet, and Web of Science databases, selecting 11 studies that addressed diverse applications of robotics, including educational robotics, robotic telepresence, human-robot interaction, and artificial intelligence applications. Their effects on teaching, the factors influencing their adoption, and the strategies used to optimize their implementation were analyzed. The findings show that educational robotics enhances student motivation and engagement, with prediction models reaching an accuracy of 98.78% in assessing academic engagement. Additionally, robotic telepresence emerges as an effective alternative for hybrid education, and social robots and AI-based tutors demonstrated their potential to personalize learning. However, methodological and structural challenges persist, such as the need to develop more accurate evaluation metrics and ensure accessibility and educational equity. Future research should focus on improving these aspects, enabling more efficient integration to enhance teaching processes. This study was registered in the Open Science Framework under the code: 10.17605/OSF.IO/KHDTU.

Solar ultraviolet (UV) radiation has increased in recent years due to ozone layer depletion and in Ecuador in particular, due to its geographical position and the height of its cities. Prolonged sun exposures in childhood increase the risk of causing malignant effects on the skin and eyes, such as squamous cell carcinoma, melanoma and cataracts. For this reason, this document describes the design of a device based on UV optical sensors that allows determining the existing radiation index. As a processing unit there is the Raspberry Pi 3B+ embedded board and to display the data physically there are LED panels. The storage of information is done through a database managed by MySQL and also implemented on the board. The levels of the ultraviolet radiation index (UVI) are presented through a graphical user interface (GUI) in real time, which also allows generating a report in a.csv file. Functional tests were carried out in the central courtyard of two educational units, to raise awareness among parents and authorities on the adoption of preventive measures that avoid possible damage to the skin of children when carrying out outdoor activities. © 2020, Springer Nature Switzerland AG.

The industrial sector, responsible for a substantial share of global greenhouse gas emissions, faces the dual challenge of advancing decarbonization while ensuring long-term competitiveness. Addressing this dilemma requires a transition toward renewable energy sources that not only reduce emissions but also enhance energy security and compliance with increasingly stringent climate regulations. This study examines the integration of renewable energy technologies into industrial processes, highlighting both opportunities and persistent barriers. On the benefits side, renewable adoption has the potential to deliver significant emission reductions, strengthen energy independence, and improve corporate reputation through alignment with sustainability targets. Nevertheless, limitations such as high initial investment costs, intermittency of supply, technological uncertainty, and unstable regulatory frameworks continue to hinder large-scale deployment. Emerging digital technologies, including machine learning for predictive maintenance and blockchain for energy traceability, are identified as enabling tools that improve efficiency, transparency, and integration across supply chains. By employing a narrative review methodology, this analysis synthesizes documented case studies and verifiable performance metrics to provide a structured view of current practices. Findings demonstrate that sector-specific renewable integration, such as solar thermal in manufacturing or green hydrogen in heavy industries is both technically feasible and economically viable under favorable conditions, yielding measurable reductions in carbon intensity. However, success depends on designing tailored strategies that consider local resource availability, fostering stable policy frameworks that reduce investment risk, and promoting cross-sector collaboration. Ultimately, a context-sensitive and adaptive approach emerges as essential to scaling industrial decarbonization without undermining competitiveness, ensuring that sustainability and productivity evolve in tandem.

The educational disorders that children present at an early age can cause them to not fully develop throughout their lives. In this research work a 3D virtual system that allows the child who has been diagnosed with dyslexia to complement the exercises performed in a conventional therapy is described. To achieve this an application was developed, the app consists of two games (each with three levels of difficulty), and that are part of the rehabilitation program. In each of these games virtual objects are combined with auditory messages to provide the user with an immersive experience, and to train more than one sense at a time. In the first game task, the activity asks the children to correctly locate the syllables that compose a word and for the second activity the children will listen to a word, after the games asks the children to select the correct word. This tool has been tested by a group of children (eight), with ages ranging from 8 to 12 years old, whose development can be supervised at home by their parents, since it is an intuitive and easy to use interface. The results obtained are stored in a database and in this way the medical specialist can monitor the progress of the child throughout his treatment. For the validation of this proposal the SUS usability test was used. © Springer Nature Switzerland AG 2020.

Access to electricity supply in remote areas is limited, despite having wealth of other natural resources such as water. This document presents the design and construction of a scale electric generation system, taking advantage of the hydraulic energy produced by a constant flow of water flow. For this, the turbine design is described, which is based on the principles of Francis and Kaplan. In addition, the structural design made in CAD/CAM software and the actual implementation of the system are shown. To determine the generated electric potential, the electromagnetic analysis is performed based on the Maxwell-Faraday equation and the respective calculations. The validation of this proposal is determined by conducting experimental tests with balanced, unbalanced, series and parallel coils and with their implementation in a home. © 2020, Springer Nature Switzerland AG.

Unmanned aerial vehicles (UAVs) are multidisciplinary technological tools, which are used in the military area for surveillance, reconnaissance and intelligence tasks in conflict zones. Due to its versatility and performance, this manuscript describes the implementation of a telemetry and video surveillance system to develop long-range missions in a UAV prototype. Communications subsystems and a ground station are integrated, with which an unmanned aerial system (UAS) is formed, carrying out the necessary calibrations and configurations. After a set of tests and the necessary adjustments, a long-distance mission is carried out and its energy consumption, height reached and trajectory tracking are analyzed. In addition, the video signal level obtained and the percentage of telemetry signal in each of the tests are established, which managed to be 90% with a distance greater than 4 km. They have good benefits, with a low economic investment, representing an interesting proposal for developing countries with a limited budget for their improvement. © 2020, Springer Nature Switzerland AG.

Virtual reality applications based on instrumental activities of daily living (iADLs) for cognitive intervention in older adults: a systematic review
(2023)

Background: In recent years, the use of virtual reality (VR) as a complementary intervention in treating cognitive impairment has significantly increased. VR applications based on instrumental activities of daily living (iADL-VR) could offer a promising approach with greater ecological validity for intervention in groups with cognitive impairments. However, the effectiveness of this approach is still debated. Objective: This systematic review aims to synthesize the effects of iADL-VR interventions to rehabilitate, train, or stimulate cognitive functions in healthy adults and people with mild cognitive impairment (MCI) and different types of dementia. Methods: A systematic search was performed in the Scopus, PubMed, IEEE Xplore, Web of Science, and APA PsycNet databases until September 2022 and repeated in April 2023. The selected studies met the search terms, were peer-reviewed, included an iADL-VR intervention, and were written in English. Descriptive, qualitative studies, reviews, cognitive assessment, non-intervention studies, those unrelated to VR or iADL, those focused on motor aspects, and non-degenerative disorders were excluded. The PEDro scale was used to assess the methodological quality of the controlled studies. To present and synthesize the results, we organized the extracted data into three tables, including PEDro scores, participant characteristics, and study characteristics. Results: Nineteen studies that met the inclusion and exclusion criteria were included. The total sample reached 590 participants, mostly women (72.67%). Approximately 30% were diagnosed with Alzheimer’s disease or dementia, and 20% had mild cognitive impairment. Variables such as authors and year of publication, study design, type of intervention and VR applied, duration of the intervention, main findings, and conclusions were extracted. Regarding demographic characteristics, the sample size, age, sex, years of education, neurological diagnosis, dropouts, and the city and country where the intervention took place were recorded. Almost all studies showed improvements in some or all the outcomes after the intervention, generally greater in the iADL-VR group than in the control group. Conclusion: iADL-VR interventions could be beneficial in improving the performance of cognitive functions in older adults and people with MCI and different types of dementia. The ecological component of these tasks makes them very suitable for transferring what has been learned to the real world. However, such transfer needs to be confirmed by further studies with larger and more homogeneous samples and longer follow-up periods.

Introduction: Virtual reality has established itself as an effective tool for analyzing user experience and simulating everyday activities. However, there are still many questions remaining, such as how the type of movement in immersive environments influences this experience. The present study evaluated these variables in a virtual supermarket developed for Oculus Quest 2, with the aim of comparing the perceptual and cognitive experience under two navigation modalities: locomotion and joystick. Methods: Twenty-two young adults (18–32 years old) participated in both groups. Usability (SUS), presence (PQ), everyday memory (PRMQ), and cybersickness (CSQ-VR) questionnaires were administered, all with moderate and high reliability (α = 0.685–0.912). Results: The results showed high levels of usability in both conditions (SUS ≥79), with no statistically significant differences between navigation modes (p = 0.521). Natural presence was significantly higher in locomotion mode (6.17 vs. 5.47); however, this result should be interpreted with caution, as it was derived from exploratory subscale-level analyses (p = 0.038). Cybersickness symptoms remained low (p > 0.05). A very strong positive correlation was also observed between usability and presence in the joystick group (ρ = 0.902; p < 0.001), indicating that interaction fluidity enhances immersion. Discussion: Both modes were ergonomic and safe, although with distinct profiles: physical locomotion increased perceptual naturalness, while the joystick reinforced the relationship between ease of use and immersion. These findings provide empirical evidence on how movement modulates the immersive experience and propose an experimental model, with implications for the design of virtual environments applicable to different populations in the future.

In this research work, a feasibility study is presented in order to install an electro-optical sensor on the Twin Otter DHC-6 aircraft of the Ecuadorian Air Force, to strengthen the strategic capacity of surveillance, reconnaissance and intelligence. The study took into consideration the limitations and restrictions inherent to the aircraft, which is why it was decided to make a temporary, non-invasive and easy to assemble installation. For the study of affectation, the aerodynamic, structural analysis, loads, weight and balance were considered. Mechanical components and a fairing have been designed in composite materials, so that the sensor attachment is safe and has an aerodynamic surface that reduces the drag coefficient generated. To validate this prototype, a comparison of the aircraft in its normal state with respect to the adhesion of this device is made through tests and simulations. © 2020, Associacao Iberica de Sistemas e Tecnologias de Informacao.
