The present study seeks to analyze the publications of articles in the Scopus database on environmental issues carried out by a private university in Peru between 2013 and 2024 through a review of bibliometric indicators in which 200 papers were selected and analyzed. The search was conducted by affiliation. The variables analyzed are: author, year, citations, journal, index, language and topics. The results allow us to see that the years 2022 and 2023 had a higher number of publications (n=54 and 52), 2017 reports a higher average total of citations per article (n=78.57), the journal with the most publications is "Marine pollution bulletin" from Switzerland with a Q2, SJR = 0.83, with 20 articles, the most relevant authors are: Alfaro-Shigueto (n=37) and Mangel JC (n=34), the clusters identified show words that are not normally associated with the field of environmental sciences such as: human, clinical study and non-human, the article with the greatest impact is "Microplastics in the Antarctic marine system: An emerging area of research", the countries in which they are published the most are Switzerland, the Netherlands, the United Kingdom, Germany and the USA. The impact level are between Q1 and Q2 with SJR = 0.39 up to 2.15.

The objective of this master's thesis was to evaluate the impact of the program of a youth orchestra in the Province of Buenos Aires on the operability of working memory, executive functions and verbal working memory with standardized tests. A transectional study was carried out, where two groups of adolescent participants were compared, with and without musical training. Significant differences were found in favor of the group with musical training in the direct digit tests, reverse digit tests and the verbal comprehension subtests (similarities, vocabulary and comprehension), adding to the studies that affirm that musical training affects working memory verbal. No significant differences were found in the other tests. Finally, it is concluded that the youth orchestra program benefits some aspects of cognitive development in its participants.

The study focuses on determining the relationship between nutrition and cognitive processes that affect academic performance in adolescent students. It is a non-experimental, quantitative, descriptive and cross-sectional research. 189 students, with an average age of 15, were selected as a sample. years. The dependent variable is made up of the school performance of the study population, determined through the Saber Tests and grade sheets and indirectly through neuropsychological tests, such as the TMT Test A and B, which measures the cognitive process of attention. and the Wisconsin test that measures executive functions and the Auditory Memory test that measures the memory process. The main independent variable of this study will be the anthropometric nutritional status of the students, determined through the calculation of BMI and hemoglobin. It is concluded that the relationship between BMI and hemoglobin with the different tests is weak, as is BMI and hemoglobin with the grades and results of the Saber Tests. Although the participating students present a high risk of acquiring eating habits that result in nutritional deficiencies. The results obtained show that the BMI in the majority is within normal ranges as well as hemoglobin, they also have good sleeping habits and the results of academic performance measured by grades and Test Saber are not as low as initially expected.

This study analyzes the impact of personalized feedback on formative assessment in higher education, considering the role of artificial intelligence in this process. A mixed-methods design with both qualitative and quantitative approaches was used, collecting data through surveys and response analysis on digital learning platforms. A total of 150 student responses from various institutions were analyzed to assess the effectiveness and perception of feedback. Results indicate that personalized feedback enhances meaningful learning and student motivation, although challenges remain for large-scale implementation. Pedagogical implications are discussed, and strategies are proposed to optimize its use in digital environments.
