The progress of commercial activity has allowed logistics to evolve and increasingly achieve decisive positions in the development of companies and their aspirations in the global market. As technological development increases, new doors open to achieve greater efficiency in logistics management, generating value and satisfaction for target customers. The logistics performance index contributes as a reference in measuring these levels of efficiency and satisfaction. Through the review of various bibliography on the subject and the analysis of the Logistics Performance Reports issued by the World Bank, we reference the current situation of Cuba and the Latin American region and reflect some elements to take into account for the insertion of these countries in the dynamic marked by industry 4.0, where the management and integration of information is of special importance.

The object of investigation is the analysis of derived experiences from the results of an application of the pyramidal structure as methodological tool for students and professors on the research activity. The reference structure includes significant contributions to the solution of the fundamental problem of the insufficient conception of the research activity if organized by hierarchical levels with absence of actions for to transfer the scientific gestion of knowledge between those levels. The experiences derived from the design and the operation of the pyramidal research structure application are described as a contribution to an innovative form of knowledge exchange and a scientific development of the research skills. Given the qualitative nature of our research, we opted for a descriptive instrumental case study based on the analysis of various theoretical approaches and results derived from a research related to location by segments, stages or levels of results, expressed in the form of a pyramidal structure. Data were collected and evaluated according to the contributions of consultancies and advisories, work practices, diploma, master's and doctoral theses, all with a predominant use of theoretical and empirical research methods. It was determined that the results of the investigating activity of the students and professors, can get significantly better when the pyramidal structure tool of investigation adhibit an integrated organization by hierarchical levels, generating an information with scientific gestion of knowledge, in an ascending and descending flow, from the conception of teamwork headed by a tutor or General Coordinator.

La gestión de la calidad reviste singular importancia en el entorno competitivo que se desarrollan las empresas actualmente. La insatisfacción de los clientes puede estar generada en muchas ocasiones por la gestión inadecuada de las ventas en las empresas, es por ello que la presente investigacióntiene como objetivo: diagnosticar el servicio de ventas en negocios particulares de alimentos y bebidas. Se emplea un procedimiento de elaboración propia basado en los diferentes enfoques de gestión de la calidad. Para su ejecución se emplean técnicas como: las entrevistas, la tormenta de ideas, el diagrama causa-efecto, diagrama As – Is, análisis operacional, encuesta, análisis estadísticos, software SPSS  y la técnica de observación continua individual. Como principal resultado se determinó que la disminución de las ventas, reflejo de una insatisfacción de los clientes, está asociada a problemas con el personal (indisciplinas del obrero, las que aumentarían la productividad un 50 %), causas no asignables, las que generan un nivel de servicio del 86 %.

Ergonomics and the Safety and Health in the university environment not only provide comfort and well-being, but are also fundamental bases in academic and work performance; Therefore, the lack of an environment governed by the principles of Ergonomics could have a direct impact on the physical and mental health of workers. That is why the objective of this research is to study the ergonomic conditions of the Career Department of the Faculty of Industrial Engineering of the CUJAE. Anthropometric measurement is used with the implementation of photometry through the ImageJ software that allowed the preparation of the table of anthropometric dimensions of the work personnel. The analysis of the data produced by this methodology made it possible to carry out a diagnosis to evaluate the means available to the Department's workers, determining several problems in ergonomic conditions.

A digital platform is characterized by creating an adequate exchange of information between institutions and users, to consolidate the creation of value for all participants. The low adaptability of society to technological changes and the scarce knowledge of the use of digital platforms is presented as a problem. The general objective is to analyze the usability of the platforms in the quality of digital services to users of the Municipality of Canton Portoviejo. A methodology with a quantitative approach was used, with a descriptive analytical scope, 384 citizens were surveyed, to whom a survey was applied. The results reflect that, within the Decentralized Autonomous Municipal Government of Canton Portoviejo, a digital transformation is required that is related to the global trend that seeks to improve efficiency, transparency and accessibility, also presenting a strategy to establish improvements on its relevance.

The diagnosis was carried out at the CIMSERVICIM Basic Business Unit (UEB) where the absence of a specialized instrument containing the following was detected; functions, techniques and methods that allow the standardization of processes and that serve as a reference for the performance of accounting work, minimizing the risks of errors and guaranteeing strict compliance with the regulations in the country. Based on this problem, the objective is to propose a Manual of Accounting Procedures for the UEB of CIM Support Services. The design of the manual consists of three stages; consultation and analysis of the reference bibliography, design of the procedures that make up the manual; validation, implementation and evaluation. As a result of the research, the proposal of the Accounting Procedures Manual was made, validating the procedures that integrate it through the judgment of experts and reflecting the results in the Mathematical Statistical System MINITAB 17

Code obfuscation is one of the techniques used for privacy against reverse engineering attacks on the source code. This research presents a model to obfuscate the call graph as a source code protection technique and its validation through the performance of white-box and black-box tests and the evaluation of the obscurity performance and the cost of the model in static reverse engineering attacks. Based on the measures that are usually used to quantify the quality of obfuscation techniques and the most common obfuscation quality attributes, the use of the degree of diversification and obfuscation achieved by the call graph of the obfuscated program ϑ(P), with respect to the original program P in the model proposed by this work is based.

This study compares the use of Operation Research tools and the Odoo v.17 ERP System. Both tools are analyzed in terms of efficiency, flexibility and applicability in different productive contexts. The methodology used to implement each approach in a specific case study is described, the results obtained are presented and the benefits and limitations of each tool are discussed. The results show that both OR and Odoo offer significant benefits, but their applicability depends on needs and data availability. The conclusion highlights the importance of selecting the appropriate tool according to the production context.

The purpose of this paper is to propose a procedure for the improvement of the Integrated Human Capital Management System applicable to all Cuban enterprises and whose primary purpose is to increase the contribution of organizations to local development through the improvement of strategic business management of human resources. The proposed procedure, taking as a reference the criteria of various authors, the legislation in force and the principle of continuous improvement, consists of four stages and the techniques proposed are direct observation and those related to the process approach, the Vester matrix, expert method, diagnostic technology, brainstorming, impact matrix, SWOT analysis, teamwork, document review, which allow enriching and supporting the activities of the procedure. Improving human capital management leads to the creation of greater capacities for local development
