University education faces a future influenced by generative artificial intelligence (AI), especially with tools like ChatGPT. The objective of this study was to map the literature to identify benefits, challenges, and ethical solutions. A bibliometric analysis and narrative review approach were used for documents from Web of Science (WOS) and Scopus in July 2024. A total of 792 WOS and 144 Scopus documents were analyzed using the search equations "Generative artificial intelligence" OR ChatGPT AND "Academic integrity." The data were processed using Bibliometrix and VOSViewer software. The bibliometrics show exponential growth in research since 2023, with a strong presence in areas such as education and computer science. The United States and the United Kingdom have led production and international collaborations with Stanford University and the University of California, San Diego, demo...

The study of the application of coatings on the pear is very scarce, for this reason the research aimed to "Evaluate the effect of beeswax and carnauba wax on the post-harvest life of pear (Packham's triumph)" The evaluation was carried out at the Universidad Privada de Tacna, Laboratory for the analysis of agroindustrial products. For this, carnauba wax and beeswax were used. Through previous experiments, treatments with beeswax (TCA), with carnauba wax (TCC) and a mixed treatment (TM, "beeswax and carnauba wax") were formulated, where it was found that the coating with greater fuel stability mix 40 % beeswax and 60% carnauba wax, for analysis purposes the parameters needed to measure were identified, such as total soluble solids (SST), titratable acidity, pH, weight, color, CO_2 and Firmness Concluding that the mixture treatment (TM, “beeswax 40% and carnauba wax 60%”) had better r...

In order to evaluate the post-harvest behavior of climacteric fruits, an experimental team was constructed to determine the intensity of respiratory rate in parts per million (ppm) of carbon dioxide (CO2) per unit of mass and time, for which purpose they were used : a K-33ICB sensor for CO2 measurement; Thomas 2000DV / 0,5 / E / LC air pump; a glass water trap with a diameter of 2.5 cm and a useful length of 6 cm; a 0.22 μm hydrophobic filter; a 150 μm particle filter; a breathing chamber with a volume of 5.0 x10-3 m3 constructed of glass with two tabulations for gas exchange and latex ducts. The Gaslab ® software was used to acquire data. In order to evaluate the equipment, Hass avocado fruits (Persea americana) were selected in the degree of physiological maturity with 8.26% of oil, then conditioned in the breathing chamber with an initial weight of one kilogram, then sealed hermeti...

The objective of the research was to estimate the relationship between changes in eating habits and emotional well-being of engineering college students at the Private University of Tacna during mandatory confinement due to COVID-19. The study was descriptive cross-sectional with a sample from 195 participants, two instruments were used; the psychometric scale of depression, anxiety and stress (DASS-21) and an instrument to measure eating habits that were validated by presenting an internal consistency value of α = 0.937 and 0.826 respectively. The variation in eating habits was evaluated using an instrument consisting of 19 items that diagnose whether the participant increased or decreased the consumption of healthy and unhealthy products. For the validation of the results, the DASS was adjusted by means of a confirmatory factor analysis that groups together the levels of stress, anxie...
