Los avances tecnológicos del entorno actual han generado una serie de retos, desplegando muchos esfuerzos a las organizaciones tanto privadas como públicas por estar en el avance de las tecnologías de la información y comunicaciones (TIC). Especialmente, las universidades como instituciones que propician el cambio y el avance de la sociedad, están inmersas en este contexto. Debido a esto desde hace años las universidades del país se han favorecido con los avances de las Tecnologías de la Información y Comunicaciones como una herramienta que propicia el desarrollo institucional y la competitividad sostenible basados en calidad. Los primeros sistemas informáticos en las universidades en la década del 1980, la dominaban los sistemas desarticulados específicos para cada requerimiento y usuario. Sin embargo, rápidamente se hace necesario el requerimiento de disponer sistemas inte...

Business intelligence provides significant assistance in decision-making by offering a comprehensive overview of the business and its workflow, presenting various alternatives to decision-makers. The research aimed to streamline decision-making within the company through the implementation of a Data Warehouse. The Kimball methodology was employed in the process, utilizing Atoti Apache Airflow and PowerBI software, which were fed with transactional data stored in a MariaDB database. Statistical analysis was conducted using R software within the RStudio environment. The study population consisted of 5 employees for the user satisfaction indicator, employing a convenience non-probabilistic sampling method, while for the indicators of report generation time and costs, the population comprised 360 management reports, sampled using a simple probabilistic method, resulting in a sample of 186 ma...

This study focused on implementing a Web System to develop the management of human and commercial talent in a supermarket, using the Scrum methodology. Sales and human resources systems were integrated to optimize customer perception and economic results, highlighting the effectiveness of Scrum in practical cases, such as the implementation of an online sales system for MSMEs caused by the health crisis caused by the spread of COVID-19. The economic results, supported by key indicators such as NPV, B/C and IRR, strengthened the viability of the project. The system was structured into three Sprints, each focused on specific stages, using the Laravel framework and performance testing with JMeter. Additionally, the development phase included the coding of all planned activities. In conclusion, this system promises to be highly beneficial to improve human and sales talent management. The eff...

The systems aim to reduce errors and costs. The objective of the information was to streamline the commercial management processes in the Rosita clothing store. Regarding the method: It was the SCRUM methodology, carried out with PHP.v8 and Laravel v9 framework, as well as MySQL Workbench 10.4.25 database; For the mobile, the Xamarin 5.9 development framework was used with the C# language, with 19 user stories stacked in 3 Sprints, executed in 98 days, at the end of which the modules will be provided. To differentiate the hypotheses, the Shapiro Wilk and Kolmogorov-Smirnov-Lilliefors normality tests were used, and inferential statistics were used using the student parametric test for paired data with a significance level of 5%. The research design was pre-experimental. The population was 14 people, the sample for the customer service time indicator was 603 clients, for information search...

The incorporation of web systems results in improved efficiency, process optimization, and greater precision in information management, generating a growing demand. In this context, the focus of this study was directed towards the implementation of web solutions aimed at optimizing the administrative management of bookstores. The SCRUM methodology was chosen as the approach for software development, characterized by its iterative and incremental nature. Thirty user stories were carried out in 3 sprints, executed on different days, each concluding with the successful implementation of a module. The results revealed a notable reduction of 38.51% in the average customer service time, with a positive impact of 61.49%. Information search experienced a significant decrease of 2.30%, with an impact of 97.70%. Additionally, the generation of receipts underwent a reduction of 33.70%, with an impa...

The emergence of Machine Learning (ML) technologies and their integration into agriculture has demonstrated a significant impact on disease detection in crops, enabling continuous monitoring and enhancing risk planning and management. This study applied image processing techniques such as thresholding, gamma correction, and the Stretched Neighborhood Effect Color to Grayscale (SNECG) method, alongside ML, to develop a predictive model for identifying five types of rice diseases. The ML techniques used included Logistic Regression, Multilayer Perceptron, Support Vector Machines, Decision Trees, and Random Forests (RF). Hyperparameters were optimized and evaluated through 5-fold cross-validation. In the results, the SNECG method successfully converted images to grayscale, capturing essential features of lesions on rice leaves. The ML models developed with these techniques showed evaluation...
