Background: While nonprofessional caregivers often experience a sense of fulfillment when they provide care, there is also a significant risk of emotional and physical burnout. Consequently, this can negatively affect both the caregiver and the person being cared for. Intervention programs can help empower nonprofessional caregivers of people with chronic diseases and develop solutions to decrease the physical and psychological consequences resulting from caregiving. However, most clinically tested intervention programs for nonprofessional caregivers require face-to-face training, and many caregivers encounter obstacles that hinder their participation in such programs. Consequently, it is necessary to design internet-based intervention programs for nonprofessional caregivers that address their needs and test the efficacy of the programs. Objective: The aim of this study was to evaluate the effectiveness of a smartphone app–based intervention program to increase positive mental health for nonprofessional caregivers. Methods: This study was a randomized controlled trial of 3 months’ duration. A total of 152 caregivers over 18 years of age with a minimum of 4 months’ experience as nonprofessional caregivers were recruited from primary health care institutions. Nonprofessional caregivers were randomized into two groups. In the intervention group, each caregiver installed a smartphone app and used it for 28 days. This app offered them daily activities that were based on 10 recommendations to promote positive mental health. The level of positive mental health, measured using the Positive Mental Health Questionnaire (PMHQ), and caregiver burden, measured using the 7-item short-form version of the Zarit Caregiver Burden Interview (ZBI-7), were the primary outcomes. Users’ satisfaction was also measured. Results: In all, 113 caregivers completed the study. After the first month of the intervention, only one factor of the PMHQ, F1–Personal satisfaction, showed a significant difference between the groups, but it was not clinically relevant (0.96; P=.03). However, the intervention group obtained a higher mean change for the overall PMHQ score (mean change between groups: 1.40; P=.24). The results after the third month of the intervention showed an increment of PMHQ scores. The mean difference of change in the PMHQ score showed a significant difference between the groups (11.43; P<.001; d=0.82). Significant changes were reported in 5 of the 6 factors, especially F5–Problem solving and self-actualization (5.69; P<.001; d=0.71), F2–Prosocial attitude (2.47; P<.001; d=1.18), and F3–Self-control (0.76; P=.03; d=0.50). The results of the ZBI-7 showed a decrease in caregiver burden in the intervention group, although the results were inconclusive. Approximately 93.9% (46/49) of the app users indicated that they would recommend the app to other caregivers and 56.3% (27/49) agreed that an extension of the program’s duration would be beneficial. Conclusions: The app-based intervention program analyzed in this study was effective in promoting positive mental health and decreasing the burden of caregivers and achieved a high range of user satisfaction. This study provides evidence that mobile phone app–based intervention programs may be useful tools for increasing nonprofessional caregivers’ well-being. The assessment of the effectiveness of intervention programs through clinical trials should be a focus to promote internet-based programs in health policies.

Smart classrooms are physical learning spaces that, using data from the environment, students and teachers, are able to provide timely and valuable information to improve teaching and learning processes and foster decision-making. In this article, we provide an overview of how artificial intelligence techniques are being used to gain insights into the teaching and learning processes by analyzing data not only from the classroom context, but also from students and teachers. We identify the latest literature addressing the use of artificial intelligence techniques with data obtained from the smart classroom, present a taxonomy for the areas of application, review the state of deployment in schools, and discuss the current limitations. From the results, we conclude that the use of artificial intelligence techniques to analyze classroom data in real settings (i.e., primary and secondary schools) is still far from common. Most proposals are in the lower range of technological readiness levels and do not consider issues such as information security and privacy. Furthermore, most proposals focus on the development of technological products and do not address their impact on learning. Our paper concludes with an outlook on future work in this area with the aim of making the smart classroom a cornerstone for the future of education.

Critically ill patients that stay in Intensive Care Units (ICU) for long periods suffer from Post-Intensive Care Syndrome or ICU Acquired Weakness, whose effects can decrease patients’ quality of life for years. To prevent such issues and aiming at shortening intensive care treatments, Early Mobilisation (EM) has been proposed as an encouraging technique: the literature includes numerous examples of the benefits of EM on the prevention of post-operative complications and adverse events. However, the appropriate application of EM programmes entails the use of scarce resources, both human and technical. Information and Communication Technologies can play a key role in reducing cost and improving the practice of EM. Although there is rich literature on EM practice and its potential benefits, there are some barriers that must be overcome, and technology, i.e., the use of sensors, robotics or information systems, can contribute to that end. This article reviews the literature and analyses on the use of technology in the area of EM, and moreover, it proposes a smart health-enhanced scenario.

To assess the effectiveness of a smartphone app-based intervention compared to a regular intervention of caregivers in primary health care institutions. The intervention is aimed at increasing positive mental health and decreasing caregiver’s burden. Randomized and controlled trial with an experimental group and a control group. Subjects: 108 caregivers over 18, with a minimum of 4 months of experience as caregivers. Description of the intervention: an intervention with a smartphone app (n = 54) or a regular intervention for caregivers (n = 54). Each caregiver installs a smartphone app and uses it for 28 days. This app offers them a daily activity (Monday-Friday). These activities are related to the Decalogue of Positive Mental Health, which was designed ad hoc by a group of experts. The outcomes will be the score of caregiver burden, the positive mental health and participant satisfaction. These results will be assessed after the first, third and sixth month. The results of this study will offer evidence of the effectiveness of an intervention using a free smartphone app. If its effectiveness is proven and the results are acceptable, this could lead to a rethinking of the intervention offered to caregivers in primary care.

Software projects are amongst the most common professional activities of computer engineers. Gaining competences on the design and development of software projects is, however, a complex issue that cannot be tackled within a single subject. In this paper, we detail the design and implementation of a teaching methodology that aims at providing a comprehensive simulation of the whole life cycle of software projects throughout the coordination of the practical exercises of subjects of different courses. The proposal consists in developing the same software project in consecutive courses under the perspective of the three main roles involved in the project development: designer, developer and director. In the second course, the students exercise the developer role in teams of 4 people under the supervision of a student of the fourth course, who acts as the director. The director has previously proposed a formal design of the project in the third course (designer role). This methodology has been successfully deployed for 4 years in the Computer Engineering Degree at the Universitat Rovira i Virgili. The results show an improvement of the skills and competences related to the three involved subjects, which include better programming quality, better team coordination and fulfilment of deadlines, as well as a much practical view of the director’s role.
