Objective: Design and validate digital educational messages on nutrition and food aimed at univer-sity students. Methodology: A descriptive and exploratory cross-sectional qualitative-quantitative study carried out in three phases: 1) nutritional-food diagnosis and design of educational messages, 2) content validation and 3) construct validation. Descriptive statistics were used for nutritional diagnosis. For content validation, expert judgment and the interclass coincidence coefficient (ICC) were obtained. For construct validation, we conducted interviews through focus groups. Results: The combined prevalence of overweight and obesity was 43.2%. The least consumed food group was fruit (5.7%). The preference for the consumption of sugary drinks differed between the sexes, being significantly higher in men compared to women. The design and content validation and con-struction of 22 digital messages were modified. The students' observations made it possible to identify aspects of the content and form of the messages that were modified and improved to achieve greater understanding and acceptance. Limitations: The study did not contemplate the im-plementation of the messages, so it is suggested to implement it to evaluate its impact on the health and nutrition of university students. Conclusions: The designed educational messages have content and construct validity, so they can be implemented in university students.

Objective: To analyze the centrality of work in professional women who perform paid activities and its impact on the construction of their work identity. Methodology: The research followed a qualitative approach, using semi-structured interviews and convenience sampling. Ten professional women participated, all self- employed  or  employed  in  the  public  or  private  sectors. Results: The interviewees' main advantage of working is financial, but they also view it as a foundation of identity and a means of contributing to society. They find meaning in work through personal development, productivity, and social recognition—key aspects for their autonomy. Regardless of their academic or professional background, the women showed a preference for working independently and having job flexibility. Despite this, they reported negative effects on their health due to workload and an imbalance between work and family life. Limitations: Although the sample is not representative, the findings highlight the importance of analyzing the meaning of work for Young women. Conclusions: The meanings that participants attribute to work are shaped by their career paths and gender-related experiences, and work constitutes a central element of their professional identity.

Objective: To analyze the Sonora Sustainable Energy Plan from an industrial policy perspective. Methodology: A systematic literature review using the SALSA framework (Search, Appraisal, Synthesis, and Analysis) focused on relevant themes. Results: Seven key factors are identified for transforming the Sonora Plan into a sustainable industrial policy: (1) institutional strengthening and participatory governance, (2) strategic planning, evaluation, and multilevel alignment, (3) strategic integration into global value chains, (4) talent development and science-industry linkages, (5) innovation, technological clusters, and industrial digitalization, (6) sustainable infrastructure and technological platforms, and (7) adaptive policies, sustainability, and public-private collaboration. Limitations: The study is limited by its reliance on secondary sources, the generalization of findings from international contexts, and the lack of empirical data on the socioeconomic impacts of the Sonora Plan. Conclusions: Transforming the Sonora Plan into a sustainable industrial policy requires a strong focus on sustainability, infrastructure development, and coordinated institutional frameworks.

Objectives: To document the knowledge that the inhabitants of Pachuca de Soto have about chile rayado and describe its uses, both in the rural areas where it is produced and in the city, where it is marketed, as well as to elaborate an infographic to disseminate information about this fruit. Methodology: Using an exploratory qualitative methodological approach, five in-depth interviews were conducted with people who work with chile rayado in the municipality of La Misión. The information and photos collected were used to create an infographic and to design a second interview, which was administered to thirty people in Pachuca de Soto. Results: Symbolically, the chile rayado is used against the “mal de ojo” (evil eye). In Pachuca, it is sold mainly in traditional markets, although some gourmet stores also distribute it. The interviewees showed interest in this local product and suggested strategies to spread more information about it. Limitations: Only people in the center of the city were interviewed, so the perspectives on chile rayado are limited to that sample; however, an attempt was made to interview men and women of different ages in an equitable manner. Conclusions: This work highlights the need to document the agro-food diversity of local products that are still commercially available in urban areas.

Objective: This study examines the influence of digital influencer credibility and the emotional connection between influencers and consumers on consumer engagement and purchase intention in the context of the typical regional beverage, bacanora, which has a designation of origin (DO). Methodology: A quantitative correlational approach was employed, utilizing multiple linear regression analysis to analyze data collected from a self-administered online survey administered to a sample of 114 influencer followers on social media. Results: The results suggest a differentiated influence. Consumer engagement is positively and significantly predicted by influencer integrity, authenticity, and similarity, but none of the credibility or parasocial interaction factors had a direct, statistically significant effect on purchase intention. Limitations: The study is limited by its cross-sectional design, which does not allow for establishing causality, by potential biases in follower responses, and by the restrictive scope of the analytical model, which excludes certain key variables that could act as mediators or moderators of the impact on purchase intention. Conclusions: It is concluded that the impact of digital influencers may be indirect, suggesting that engagement could mediate the relationship between influencer characteristics and purchase intention. Future research should explore these mediating variables.

Introduced fish can threaten aquatic biodiversity. Peru is a megadiverse country; its northern coast (Tumbes, Piura, Lambayeque, and La Libertad) exhibits greater fish diversity than its central and southern regions. In this area, introduced species exist; however, no research has been found that consolidates data on them. The aim of this research was to prepare a systematic review of introduced and potentially invasive fish in the northern coast of Peru. Following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) from 2020, 2,665 documents were obtained from Scopus, WoS, ScienceDirect, SciELO, PubMed, and Google Scholar. After removing duplicate documents and applying inclusion and exclusion criteria, six documents were selected. Eight additional documents were obtained from other sources. A total of 12 introduced species were reported: common carp (Cyprinus carpio), gambusia (Gambusia affinis), guppy (Poecilia reticulata), swordtail (Xiphophorus hellerii), tilapia (Coptodon rendalli), blue tilapia (Oreochromis aureus), Mozambique tilapia (Oreochromis mossambicus), Nile tilapia (Oreochromis niloticus), wami tilapia (Oreochromis urolepis), cobia (Rachycentron canadum), rainbow trout (Oncorhynchus mykiss), and hypostomus (Hypostomus sp.). Of these, five species were cichlids and three were poeciliids; eleven species were found in freshwater, five in mangroves, and two in the sea. Tumbes recorded the highest number of waterbodies with introduced species, Piura recorded the highest number of species (eight), while Lambayeque reported only one species in a waterbody. Seven species (common carp, gambusia, guppy, tilapias - blue, Mozambique, and Nile - and rainbow trout) have a high invasive potential, as they are among the 100 worst invasive species in Europe or worldwide. The evaluated documents have only reported the presence of introduced species without delving into their impact on ecosystems; therefore, further research in this direction would be advisable.

The objective of this study was to evaluate occupational risk factors in the Engraving, Sculpture, and Ceramics workshops of the Faculty of Arts at the Central University of Ecuador, considering current occupational health and safety regulations. Methodologies from the National Institute for Occupational Safety and Health (INSHT) were applied to measure noise and lighting levels, along with the IPMAQ methodology to assess the hazard level in the handling of chemical agents. The results showed that the Engraving Workshop presents a very high chemical hazard index (Q4), due to the handling of substances such as metallic oxides, solvents, and pigments without adequate ventilation or systematic use of personal protective equipment. This environment represents a critical health risk for students and staff, requiring immediate intervention. Regarding noise, the sculpture workshops in metal, wood, marble, and stone showed a medium risk level, caused by the continuous use of electric tools and heavy machinery. Although the maximum permissible levels were not exceeded, prolonged exposure may lead to adverse effects such as hearing loss or occupational stress. In terms of lighting, all evaluated workshops exhibited significantly lower levels than those required by Ecuadorian regulations, qualifying as high risk. This deficiency increases the likelihood of errors, visual fatigue, and accidents during the use of tools. It is concluded that it is essential to redesign ventilation and lighting systems, provide continuous training to workshop users, and promote an active culture of prevention. The joint participation of academic authorities, faculty, and students is key to ensuring safe and healthy environments, in alignment with the principles of educational quality and occupational well-being.

Knowledge of the geological evolution of the Oriente Basin is concentrated towards the north, here the information is abundant due to the presence of oilfields. In the southeastern area of the Oriente Basin, the available data is 2D seismic sections and a few exploratory wells with information from the Cretaceous to the most recent sequences. Hence, the geological interpretation of the pre-Cretaceous in this area is scarce. In contrast, the Peruvian side (Marañón Basin) has enough geological data and interpretations which are detailed in the models proposed by Calderón et al. and Zamora et al., that support this study. The delineation and interpretation of seismic facies allowed the recognition of pre-rift, syn-rift, post-rift, tectonic inversion, and evaporite uplift tectonic events associated with pre-Cretaceous lithologies. This study allowed the identification of the middle to upper Triassic extensional event that is absent towards the northern part of the Oriente Basin, and the Intra-Jurassic unconformity which is well marked towards Peru. The results are the first approximation to the understanding of the geological evolution of the study area in the transition of the Peruvian and Ecuadorian Andes. 

The consumption of natural spring mineral water has been growing worldwide in recent years, representing a market worth millions of dollars. Bottled mineral water from natural springs is a non-sterile product with an indigenous bacterial microbiota, which is why it requires periodic studies to guarantee its safety. Therefore, the objective of the work was to determine the bacteriological quality of bottled natural mineral water at the time of its commercialization in the city of Quito, quantifying different bacterial groups that are indicators of sanitary quality. Samples of bottled natural mineral water were obtained randomly in commercial establishments, evaluating five brands of bottled natural mineral water without gas. From each brand of bottled water, a total of eight plastic bottles with a volume of 1.50 liters of water from the same batch were collected during two sampling campaigns. The groups of heterotrophic bacteria, total and fecal coliforms, as well as the group of bacteria of the Pseudomonas quantified using the membrane filtration technique. The results obtained in the bacteriological analysis show the presence of heterotrophic bacteria in a range of 1.2 x 10 CFU/100 mL to 1.6 x 103 CFU/mL and bacteria of the Pseudomonas in a range of 2.0 x 10 at 5.2 x 10 CFU/100 mL. The presence of total coliforms and Escherichia coli was not observed in the samples analyzed. The results show higher numbers of bacteria than those established in national and international regulations.

The circular economy represents a modern production and consumption paradigm aimed at ensuring long-term sustainability. In the automotive sector, there is a rapid shift towards electric vehicles powered by batteries. These batteries, containing valuable metals such as lithium (Li), iron phosphate (FePO4), cobalt (Co), nickel (Ni), and others, become a significant social and environmental concern after their use in electric vehicles. This study explores the technical options for end-of-life lithium batteries from electric vehicles within a circular economy framework. It aims to recommend appropriate recycling techniques based on the compositions typically found in electric vehicle batteries in Ecuador. The methodology employed was qualitative descriptive, involving the search, evaluation, and analysis of factual information. After reaching the end of their useful life, the technical options for these batteries include reuse and recycling. Reuse involves assessing their condition for potential applications in residential and industrial sectors. Recycling aims to recover metals and materials through techniques such as mechanical and chemical treatments, including direct recycling. It is concluded that there are four technical possibilities for used electric vehicle batteries. In Ecuador, most electric vehicles are equipped with lithium batteries using LFP (lithium iron phosphate) technology, thus enabling the recommendation of an effective recycling technique to recover these high-value metals.
