    The health-disease situation of the population and health care delivery services are continuously monitored by epidemiological surveillance systems and health information systems, but since the first cases of COVID-19 appeared in December 2019 and spread globally, each country tried to control the virus by activating their own health protocols, but they became insufficient to face the pandemic and every control attempts seem impossible to all humanity, even more without the support of information technologies, which provides a rapid response for decision-making. Being that the reason why surveillance systems should help mitigate the spread of diseases and, at the same time, plan resources to protect the health status of citizens. Therefore, the aim of this article is to propose a model of a digital epidemiological surveillance 4.0, considering the current technological revolution and the constant evolution of the Internet. This model is divided into 4 phases: situational analysis, planning, execution and evaluation, and supported on 4 key components: logistic support, digital privacy and data protection, communication and technology, and disruptive innovation. A quantitative type of research was applied in a sample of 58 participants, all working as health staff in Chiclayo-Peru, to whom a data collection instrument, based on digital forms and interviews with medical epidemiologists, was applied, that information, which mainly considers the perception and perspectives of the epidemiological surveillance system, served as the basis for the proposed model.

    Aplicación del ultrasonido para conservar las propiedades antioxidantes de la pitahaya
    (Latin American and Caribbean Consortium of Engineering Institutions, 2024-01-01)
    Escribano Siesquén, William Enrique
    Pitahaya fruit has a considerable content of antioxidant and nutraceutical substances. Traditional techniques and thermal treatments used in fruit processing alter the phytochemical and nutritional components and limit their utilization, so a modern and suitable technology was sought to help preserve its components, finding ultrasound as one of the techniques that favors the preservation of the nutritional properties, bioactivity and antioxidants of the fruit pulp and its derived or processed products. In the processing of the pitahaya, the pulp was extracted by cutting it into slices and freezing it at -50°C, then freeze-drying it for about 49 hours. The dry ground sample was macerated in methanol for 7 days, separated into portions to determine the antioxidant capacity by DPPH method and analyzed by spectrophotometer. In a filtered portion, the antioxidant capacity was determined directly, and other portions were subjected to ultrasound before analysis, evaluating the times, power and frequency of application in order to preserve the natural antioxidant and nutritional composition of the pulp; it was found that the sample to which ultrasound was applied for 20 minutes at 180 W power and 40 kHz frequency was the most relevant to preserve the antioxidant capacity of the pitahaya pulp. © 2024 Latin American and Caribbean Consortium of Engineering Institutions.

    Digital transformation has become constant and has forced governments to reevaluate the validity of their educational models; therefore, regarding digital and information literacy, to train teachers to improve new digital skills becomes essential. For these reasons, this research will explore the instruction of teachers in digital and information literacy in basic education; likewise, there will be an observation of the research’s theoretical-methodological characteristics related to these variables, and, also, we will carry out an analysis of the most pertinent contributions on the impact of new literacies and competencies in the teaching–learning processes in basic education, with the purpose of obtaining a current state overview of its teacher training within the framework of the technologies’ usage linked to teaching. This review was based on the guidelines of the PRISMA protocol, and to select 56 documents, the Scopus and Web of Science (WoS) databases were used. The results show that, in the Scopus database, Spain is the country with the most research on the subject, with 29% of the total, followed by Indonesia, with 6%, and the United States, with 4%, and that the articles focus mainly on the social sciences and computer science. Likewise, in WoS, the country with the most research on the subject is Spain, with 30%, followed by Russia, with 10%, and Norway, with 8%, and the articles mainly revolve around the categories of education and communication. The research related to this topic uses a quantitative approach in 68%, a qualitative approach in 25% and a mixed approach in 7%. It was shown that there is a direct relationship between digital and information literacy and digital competency. In addition, it is also emphasized that digital and information literacy are continuous and long-term processes. More didactic proposals on digital skills would be necessary, over government policies and efforts, to achieve a community with a high level of digital and information literacy.

    This systematic review analyzed a total of 109 scientific articles with the aim of identifying, organizing, and synthesizing academic output related to digital literacy, technology adoption in agricultural sectors, digital skills, and socioeconomic and cultural factors that influence the implementation of emerging technologies. Peer-reviewed academic publications available in open access and written in English were reviewed, complying with the PRISMA protocol guidelines. They came predominantly from Europe, Asia, and Latin America, which allowed for a global perspective. Quantitative, qualitative, and mixed approaches were applied, highlighting the use of surveys, interviews, and bibliometric analysis. Factors affecting the adoption of precision agriculture by smallholder farmers, challenges for the implementation of technologies in rural contexts, and sociocultural barriers to technological innovation were evaluated. The trend focuses on the need for sound public policies, continuous training strategies, technological accessibility, and contextualized approaches to ensure effective technology adoption. In conclusion, a broad and critical overview of the advances, limitations, and challenges surrounding digital literacy and technology adoption is provided as a basis for an in-depth debate on the digital transformation of contemporary agriculture.

    The transition to more sustainable and climate-resilient agriculture is an urgent challenge in agricultural regions of developing countries such as Lambayeque (Peru), especially in rice cultivation. In this context, digital literacy is emerging as a key enabler for accessing climate data, adopting precision agriculture technologies, and implementing sustainable agricultural practices. However, there are gaps linked to sociodemographic variables such as age, which can moderate these technology adoption processes. The objective of this study was to analyze the patterns of association between digital literacy, access to finance, risk perception, and the adoption of sustainable agricultural practices, and to examine whether age moderates the association between digital literacy and access to climate data. To this end, a quantitative, non-experimental approach was applied, using Partial Least Squares Structural Equation Modeling (PLS-SEM). The sample consisted of 101 rice farmers in the Lambayeque region, who were given a validated questionnaire that included five theoretical constructs measured using Likert scales. The results of the structural model confirmed that digital literacy has a positive and significant association with access to climate data (β = 0.461, p < 0.001) and with the adoption of sustainable agricultural practices (β = 0.259, p = 0.015). A positive association was identified between access to finance and risk perception (β = 0.411, p < 0.001). Age was negatively associated with digital literacy (β = −0.196; p = 0.027); however, the formal moderation test (DL × Age) was not significant (β = −0.054, p = 0.421), so there is no evidence that age moderates the association between digital skills and access to climate information. These findings support the design of differentiated interventions that incorporate intergenerational digital training, inclusive financing policies, and hybrid technology transfer strategies tailored to access gaps. Taken together, the evidence is consistent with the idea that reducing the digital divide can strengthen agricultural sustainability and climate resilience in rural contexts in Latin America.

    The interaction of the university and its context determines the policies to ensure that research and development (R+D) have a positive impact on society. However, innovation and entrepreneurship (I+E) have been generating new scenarios and policies in the university. The aim of this study is to identify models for R+D+i+e interaction between the university and its context. In this research, a systematic mapping study (SMS) was performed in five digital libraries. In the process, 13,561 articles were obtained and 336 articles selected as primary studies. In the literature, 17 interaction models for R+D+i+e interaction between the university and its context were identified. The most reported models are: Industrial University, Triple Helix, Entrepreneurial University, Open Innovation and Stakeholders. Likewise, the main types of activities linked to the identified models are: research, innovation and the combination of research and development. In contrast, there are few for experimental development and entrepreneurship. © 2024 Latin American and Caribbean Consortium of Engineering Institutions. All rights reserved.

    We live in an increasingly digitalized and competitive world, so the use of technological resources in continuing education is essential. The objective was to determine the impact of the MOOC based on the flipped classroom methodology on the level of information competence and information literacy in primary school teachers. The approach was quantitative, pre-experimental design. The sample consisted of 810 teachers from the Lambayeque region. After the MOOC application, it was found that the competency of navigation, search and filtering of information, data and digital content obtained the highest score, with 2.84 in the pretest and 3.67 in the posttest on a scale of 1 to 5. The conclusion is the need to train teachers so that they are able to respond effectively and efficiently to the new challenges of this digital society.
