    Universities and companies have decision-making processes that allow to achieve institutional objectives. Currently, data analysis has an important role in generating knowledge, obtaining important patterns and predictions for formulating strategies. This article presents the design of a business intelligence governance framework for the Universidad de la Costa, easily replicable in other institutions. For this purpose, a diagnosis was made to identify the level of maturity in analytics. From this baseline, a model was designed to strengthen organizational culture, infrastructure, data management, data analysis and governance. The proposal contemplates the definition of a governance framework, guiding principles, strategies, policies, processes, decisionmaking body and roles. Therefore, the framework is designed to implement effective controls that ensure the success of business intelligence projects, achieving an alignment of the objectives of the development plan with the analytical vision of the institution

    En los 煤ltimos a帽os la deserci贸n ha sido una de las principales problem谩ticas de las universidades en Colombia y el mundo. Por otro lado, se ha identificado el gran potencial que tiene la implementaci贸n de inteligencia de negocio (BI), en donde la tecnolog铆a inform谩tica le ofrece herramientas al gerente para la toma de decisiones. En un proceso tan importante como el de la gesti贸n de la retenci贸n estudiantil, se plantean proyectos de BI para la visualizaci贸n de tableros de control e identificaci贸n de patrones para predecir que estudiantes son posibles desertores. Sin embargo en un ecosistema en donde se pueden ejecutar diversos tipos de proyectos de BI, donde intervienen diferentes dependencias y es necesario asegurar la entrega de valor; es necesario la implementaci贸n de Gobierno. El Gobierno de BI es un concepto reciente y poco implementado. Sin embargo en la Universidad de la Costa se ha identificado el escenario perfecto para construir una propuesta de marco de gobierno en inteligencia de negocio, enfocado principalmente en el proceso de deserci贸n. Con este proyecto se logr贸 proponer un modelo, procesos, roles, principios, pol铆ticas, estrategias y un 贸rgano de decisi贸n llamado BICC. Para el desarrollo de la propuesta fue necesario en primera instancia un diagn贸stico del nivel de madurez en el cual se encuentra el BI en la instituci贸n. Posteriormente a trav茅s de una an谩lisis se pudo construir una propuesta alineada a la estrategia de la universidad

    Ingenier铆a de SistemasThis thesis proposes the design, development, training and deployment of a web platform as a support tool to manage and evaluate quickly and simultaneously the different actors involved in a self-evaluation. This software allows you to store all the necessary information for self-evaluation process, also trace it and facilitates the collection of statistics that provide an analysis, which is necessary to give some judgments that will define how far an academic program of excellence is in terms of education鈥檚 quality. For the development of the platform we achieved the integration of two major market frameworks: Joomla and ExtJS. The first one gives us all the libraries for the ACL, session management, mail and application logic. And the other one offers us a variety of web鈥檚 controls which interact to the server, with an asynchronously way from the browser to make queries and storages in the database without reloading the web page, adding to the usability of the software. Through this project we replaced the pencil, paper or Excel macros that try to be instruments for the surveys implementations; for a complete web platform which is going to be scalable, concurrent, stable, secure and easily accessiblea presente tesis propone el dise帽o, desarrollo, capacitaci贸n y despliegue de una plataforma web como herramienta de apoyo para gestionar y evaluar de forma r谩pida y simult谩nea los diferentes actores que participan en un proceso de autoevaluaci贸n.

    La Ley Sarbanes-Oxley permite garantizar la integridad de la informaci贸n financiera de las empresas que cotizan en bolsa, y su principal objetivo es proteger al inversionista. Actualmente y con la intensi贸n de proteger los datos, las empresas almacenan y gestionan su informaci贸n financiera en infraestructuras tecnol贸gicas y sistemas inform谩ticos propios. Por otra parte, COBIT 5 es el marco de trabajo que se implementa para gobernar las Tecnolog铆as de la Informaci贸n (TI) y asegurar la alineaci贸n de TI a la visi贸n de la organizaci贸n. Sin embargo, COBIT no posee las herramientas que posibiliten el tratamiento en detalle de la informaci贸n financiera; por tal raz贸n, aqu铆 se propone articular COBIT 5 y el Marco Integrado de Control Interno del Committee of Sponsoring Organizations of the Treadway Commission (COSO ICIF), fundamentados en los lineamientos expuestos por las normas ISO 38500 e ISO 27001, para dar cumplimiento a la Ley Sarbanes-Oxley. Como resultado de esta articulaci贸n se obtuvo una gu铆a para el auditor financiero, que le permita definir controles de calidad basados en buenas pr谩cticas de controles de TI. Para lograr esto, se realiz贸 una alineaci贸n de los procesos de COBIT con los principios de cada uno de los componentes de COSO IC-IF. Adicionalmente, se propuso c贸mo evaluar el cumplimiento de los requisitos de la Ley desde una perspectiva de TI, aplicando buenas pr谩cticas en la implementaci贸n del control y la referenciaci贸n de los procesos de COBIT 5.The Sarbanes-Oxley Act makes it possible to guarantee the integrity of the financial information of listed companies, and its main objective is to protect the investor. Currently, in an effort to protect data, companies store and manage their financial information in their own technology infrastructures and IT systems. On the other hand, COBIT 5 is the framework that is implemented to govern Information Technology (IT) and ensure the alignment of IT to the organization's vision. However, COBIT does not have the tools that enable the detailed treatment of financial information; For this reason, it is proposed here to articulate COBIT 5 and the Integrated Framework of Internal Control of the Committee of Sponsoring Organizations of the Treadway Commission (COSO IC-IF), based on the guidelines set forth by the ISO 38500 and ISO 27001 standards, to comply To the Sarbanes-Oxley Act. As a result of this articulation, a guide was obtained for the financial auditor, allowing him to define quality controls based on good practices of IT controls. To achieve this, an alignment of the COBIT processes was performed with the principles of each of the components of COSO IC-IF. Additionally, it was proposed how to evaluate compliance with the requirements of the Law from an IT perspective, applying good practices in the implementation of the control and referencing of COBIT 5 processes

    Agriculture, and natural resources associated to its development like water, soils and forests, have a relevant role in the future of countries and environmental conservation. The optimization of these resources is made with the implementation of technological strategies and tools that make it possible. In this sense, we developed a monitoring prototype for agronomic variables in cassava crops (Manihot Esculenta Crantz) in the Atl谩ntico department (Colombia) based in WSN using Z1 motes as hardware platform and the temperature and soil moisture sensor SHT11. The operating system used was Contiki, and the routing protocol was RPL. The Network Performance Metrics evaluated were packet loss, RSSI (Received Signal Strength Indicator), LQI (Link Quality Indicator) and network convergence time. Then, a deployment model using Schl盲fli notation to determine the location and number of nodes, also we calculated the coverage range of the nodes to keep network uniformity. With these calculations, we obtained the linkage budgets between specks, and results were validated with RadioMobile software. Then, test fields were made in a cassava crop located in the city of Manati, Atl谩ntico. Finally, with the help of server client architecture XAMPP, all data was stored and visualized through SIMCA (Agricultural Crop Information and Monitoring System), a web application developed by authors
