Predicting enrollment in Special Basic Education in Peru using the Prophet algorithm

2025-07-18T05:04:07+00:00

The present study aimed to predict national enrollment in Special Basic Education (SBE) in Peru for the year 2025, based on the analysis of historical records from the 2019–2024 period. SBE, as a modality aimed at students with Special Educational Needs (SEN), represents a fundamental pillar in building an inclusive and equitable educational system. For this study, an official database from the Peruvian Ministry of Education (ESCALE) was used, which includes a total of 23,905 records with variables such as year, department, educational level, type of management, and number of enrolled students (TALUMNOS). After filtering and cleaning the data, the Prophet algorithm, specialized in time series modeling, was applied to estimate enrollment by level (Preschool, Primary, and Total Basic) for the year 2025. The results show a stabilization of enrollment around 28,371 students, very similar to the total recorded in 2024, suggesting a possible maturity in the SBE coverage system. The model’s accuracy was validated using statistical metrics, obtaining a coefficient of determination (R²) higher than 0.85 at all levels, and an R² of 0.9999 for the national total. Additionally, the MAE, RMSE, and MAPE values reflect excellent fit and low deviation. This study demonstrates the potential of machine learning models in inclusive educational planning and offers a useful tool for the formulation of public policies aimed at students with special educational needs (SEN).

Influence of metal sulfides on the strength of concrete with aggregates from the Tucsipampa quarry, Huancavelica

2025-09-23T19:41:25+00:00

This study analyzes the influence of metal sulfides present in aggregates from the Tucsipampa quarry, located in the province of Angaraes, Huancavelica, on the mechanical strength of concrete. The presence of minerals such as pyrite, chalcopyrite, and arsenopyrite was identified, which, when reacting with water and oxygen, generate byproducts that affect the durability and strength of concrete. Through physical-mechanical tests and petrographic analysis, it was determined that mixtures incorporating these aggregates present a significant decrease in their compressive strength, especially at older curing ages. Metal sulfides cause expansive reactions and increase internal porosity, compromising the concrete structure. As a result, it is concluded that the Tucsipampa aggregates require pretreatment or replacement with sulfide-free materials for use in civil works. This study seeks to raise awareness about the importance of mineralogical analysis in aggregates and contribute to improving the quality of construction in areas with a high presence of metal sulfides.

Environmental management in responsible and sustainable mining

2025-06-28T20:34:49+00:00

This article aims to analyze how sustainability has been addressed in the mining sector through a systematic review of recent academic literature. To do so, we used a qualitative and descriptive approach, reviewing studies published between 2021 and 2025 in the Scopus, Scielo, and Google Scholar databases. The reviewed research demonstrates a growing interest in incorporating responsible practices that mitigate negative impacts on the environment and promote local development. Common challenges are also identified, such as the weak implementation of environmental regulations, the need to strengthen community participation, and the key role of technological innovation. It concludes that, although significant progress has been made, gaps persist in the effective coordination of public policies, business strategies, and social expectations. This review provides a critical perspective on current trends and limitations surrounding sustainability in the mining sector, offering avenues for reflection for future research and more inclusive and sustainable policies.

Subsidence risk in the urban area of Lircay - Huancavelica

2025-07-25T05:18:31+00:00

Throughout history, vertical ground subsidence has occurred in many parts of the world, with rates ranging from several meters to just a few millimeters per year. This phenomenon is known as soil subsidence, which may have natural or anthropogenic origins. It is considered a geological hazard capable of causing material damage and even fatalities, thus representing a significant risk. Subsidence associated with karstification is caused by the indirect dissolution of calcium carbonate in carbonate rocks due to the action of water, which gradually dissolves the rock and forms cavities and caves. This, in turn, can lead to ground collapse, posing danger and vulnerability to exposed elements such as infrastructure, buildings, and people. The objective of this study is to identify areas that are relatively susceptible to vertical displacements (subsidence) and to understand the dynamics of hazard and vulnerability areas in order to assess the risk of soil subsidence in the Pueblo Nuevo and Santa Rosa sectors of Lircay. The methodology focused on identifying the causes of subsidence and the exposed elements. The results reveal a very high-risk level in 1.5% of the area, high risk in 4%, medium risk in 9%, and low risk in 85.5% of dwellings, due to the potential for ground collapse. It is concluded that the overall risk level ranges from low to medium, primarily due to the presence of calcareous soils, which, when in contact with rainwater, form karstic landscapes followed by subsidence.

Research Culture and its Influence on the Scientific Production of University Students

2025-07-19T05:03:03+00:00

This quantitative, descriptive, and cross-sectional study analyzed the influence of research culture on the scientific production of 305 accounting and financial sciences students from the National University Jorge Basadre Grohmann, Tacna, Peru, using census sampling and structured questionnaires with 20 items per variable (Cronbach's Alpha of 0.87), analyzed with SPSS v26 via descriptive statistics, Spearman's correlation, and linear regression. The results revealed a positive and significant correlation between research culture and scientific production, where commitment to research, participation in scientific activities, and knowledge of regulations were the most influential predictors. Furthermore, students in advanced cycles showed higher indices in both variables. Despite these findings, barriers such as limited access to databases, insufficient methodological training, and a lack of incentives were identified. It's concluded that strengthening research culture is crucial for increasing university scientific production. Implementing comprehensive strategies that promote early training, improve access to resources, and establish incentive programs is recommended to boost knowledge development in Latin American higher education.

Teaching perceptions and experiences in the use of generative artificial intelligence in higher education

2025-07-17T05:56:17+00:00

This study analyzes the perception and experiences of 42 higher education teachers regarding the use of generative artificial intelligence (GAI), especially ChatGPT. The data was obtained from a public dataset. The quantitative results reveal a predominantly favorable perception towards GAI, highlighting its usefulness in improving the educational experience, optimizing material preparation, and facilitating content comprehension. Teachers value the time savings and adaptability of these tools. However, there is greater caution and diversity of opinions concerning the promotion of critical thinking and learning assessment, suggesting reservations about their application in complex pedagogical processes. In addition to the preference for ChatGPT, the active exploration of other complementary tools (such as Humata.ai, ChatPDF) is evident, indicating a proactive attitude towards technological innovation. The study emphasizes the need for specific training, institutional support, and clear ethical frameworks for effective and responsible GAI integration. This research contributes empirical evidence in the Latin American context, an area with a scarcity of studies on the teacher's voice in this field.
