CATASTROAGRI -- Interactive data analysis and visualization application with a future projection for catastrophic agricultural insurance
CATASTROAGRI is an application developed to load, analyze and interactively
visualize relevant data on catastrophic agricultural insurance. It also focuses
on the analysis of an ARIMA (0,1,1) (0,1,1) model to identify and estimate
patterns in the agricultural data of the Puno Region, it presents a decreasing
trend because there is a significant relationship between successive values of
the time series, We can also state that it is not stationary because the mean
and variance do not remain constant over time and the series has periods, and
it is observed that the cases are decreasing and increasing over the years,
especially the amount to indemnify due to the behavior of the climate in the
highlands. The results of the analysis show that agricultural insurance plays
an important role in protecting farmers against losses caused by adverse
climatic events. The importance of concentrating resources and indemnities on
the most affected crops and in the provinces with the highest agricultural
production is emphasized. The results of the users' evaluation showed a high
level of satisfaction, as well as ease of use.Comment: In the process of sending magazine

Prediction of breast cancer with 98% accuracy
Abstract Cancer is a tumor that affects people worldwide, with a higher
incidence in females but not excluding males. It ranks among the top five
deadliest types of cancer, particularly prevalent in less developed countries
with deficient healthcare programs. Finding the best algorithm for effective
breast cancer prediction with minimal error is crucial. In this scientific
article, we employed the SMOTE method in conjunction with the R package Shiny
to enhance the algorithms and improve prediction accuracy. We classified the
tumor types as benign and malignant (B/M). Various algorithms were analyzed
using a Kaggle dataset, and our study identified the superior algorithm as
logistic regression. We evaluated algorithm performance using confusion
matrices to visualize results and the ROC Curve to obtain a comprehensive
measure of performance. Additionally, we calculated precision by dividing the
number of correct predictions by the total predictions Keywords Breast cancer,

Autoconfianza y su relación con el rendimiento, procedencia, logros y edad en jugadoras de voleibol peruanas en categoría de formación
The objective of the present research was to determine the relation between the self-confidence and the performance, place of origin, achievements and age of Peruvian volleyball players players in training category. This is a non-experimental, correlational, cross-sectional study. A total of 86 volleyball players, between 12 and 16 years old (age M=15.59-TD=0.74) were studied. The sports confidence inventory was applied to these volleyball players (reproducibility of .992). The results show that there is a statistically significant positive correlation between lack of confidence and performance (r = .310; p < .01), lack of confidence and provenance (r = .280; p < .01); confidence and age (r = .244; p < .05); overconfidence and achievements (r = .235; p < .05); level of self-confidence and age (r = .236; p < .05). On the other hand, there is a negative correlation, also statistically significant, between confidence and provenance (r = -.342; p < .01); overconfidence and yield (r = -.399; p < .01); self-confidence level and provenance (r = -.387; p < .01). It is concluded that self-confidence is to a large extent associated with sports performance, the geographical region from which they come and the age of the volleyball players, except with the sports achievements obtained in training category.El objetivo de este estudio fue determinar la relación de la autoconfianza con el rendimiento, procedencia, logros y edad en voleibolistas peruanas en categoría de formación. El estudio es de naturaleza no experimental, transeccional correlacional. Se estudió a 86 voleibolistas, de edades entre 12 y 16 años (M=15.59-DT=0.74), a quienes se les aplicó el inventario de confianza deportiva (reproductividad de .992). Los resultados demuestran que existe una correlación positiva, estadísticamente significativa, entre falta de confianza y rendimiento (r = .310; p < .01), falta de confianza y procedencia (r = .280; p < .01); confianza y edad (r = .244; p < .05); exceso de confianza y logros (r = .235; p < .05); nivel de autoconfianza y edad (r = .236; p < .05). Por otro, que existe una correlación negativa, también estadísticamente significativa, entre confianza y procedencia (r = -.342; p < .01); exceso de confianza y rendimiento (r = -.399; p < .01); nivel de autoconfianza y procedencia (r = -.387; p < .01). Se concluye que la autoconfianza en gran medida se asocia con el rendimiento deportivo, región geográfica de donde provienen y edad que presentan las voleibolistas, excepto con los logros deportivos obtenidos en categoría de formación.
