El estudio tuvo como objetivo general, establecer la relación entre la aplicación del modelo de tutoría y el mejoramiento de la calidad educativa en alumnos de la Universidad Peruana Unión, quienes cursaron estudios en el periodo lectivo 2016 – 2017. El estudio tuvo un enfoque cuantitativo, el tipo de estudio es sustantivo o de base, con un diseño descriptivo correlacional. El tipo de hipótesis empleado es el de correlación bivariada; en el que se busca establecer la relación o covarianza de las variables. Los instrumentos utilizados fueron dos cuestionarios para evaluar la aplicación del modelo de tutoría y la calidad educativa. La muestra estuvo constituida por 127 alumnos. La validación de los instrumentos se realizó mediante el juicio de expertos, mientras que la confiabilidad se realizó mediante la prueba de Alfa de Cronbach. Para establecer las correlaciones se tuvo ...

“Background: The great difference in scientific production among countries, especially in Latin America and the Caribbean, may be related to the economic growth of each nation, but countries with larger economies do not necessarily have higher scientific production. Political changes and unstable economies result in little sustainability of scientific production in the countries in these regions. The purpose of this study was to determine the impact of economic growth on scientific production, measured as the variation in the gross domestic product and the number of scientific publications, in Latin American and Caribbean countries. Methods: The analyzed information was collected from the open data source of the World Bank for the years from 2000 to 2018. The analysis was performed using unbalanced data panel models that cross-sectionally considered the countries of Latin America and t...

Objective: To assess the antibacterial activity of Psidium guajava fractions and their effects on adhesion of a multispecies biofilm consisting of Streptococcus gordonii, Fusobacterium nucleatum, and Porphyromonas gingivalis in vitro. Material and Methods: Guava leaves were obtained from the mountains of northern Peru, where they grow wild and free of pesticides. The antimicrobial activity of 25 mg/mL petroleum ether, 25 mg/mL dichloromethane and 25 mg/mL methanol fractions of P. guajava was evaluated by measuring inhibition halos, as well as the effect on the adhesion of multispecies biofilms at 4, 7 and 10 days of growth by measuring the optical density. In addition, antimicrobial susceptibility was compared using the Kruskal-Wallis test and its multiple comparison tests, and differences in mean biofilm adhesion between each fraction were assessed by repeated measures analysis and the ...
