    La Inteligencia de fuentes abiertas (OSINT) es una rama de la ciber inteligencia usada para obtener y analizar información relacionada a posibles adversarios, para que esta pueda apoyar evaluaciones de riesgo y ayudar a prevenir afectaciones contra activos críticos. Este ar-tículo presenta una investigación acerca de diferentes tecnologías OSINT y como estas pueden ser usadas para desarrollar tareas de ciber inteligencia de una nación. Un conjunto de transformadas apropiadas para un contexto colombiano son presentadas y contribuidas a la comunidad, permitiendo a organismos de seguridad adelantar procesos de recolección de información de fuentes abiertas colombianas. Sin embargo, el verda-dero aprovechamiento de la información recolectada se da mediante la implementación de tres modelos de aprendizaje automático usados para desarrollar análisis de sentimientos sobre dicha información, con el fin de saber la posición del adversario respecto a determi-nados temas y así entender la motivación que puede tener, lo cual permite definir estrategias de ciberdefensa apropiadas. Finalmente, algunos desafíos relacionados a la aplicación de técnicas OSINT también son iden-tificados y descritos al respecto de su aplicación por agencias de seguridad del estado.Open source intelligence (OSINT) is a cyber-intelli-gence branch used to obtain and analyze information related to potential adversaries, so it can support risk assessments and help to prevent damages against cri-tical assets. This paper presents a research about diffe-rent OSINT technologies and how these can be used to perform cyber intelligence tasks of a nation. A set of transforms addressed to the Colombian context are pre-sented, which were implemented and contributed to the community allowing to the law enforcement agencies to develop information gathering process from Colombian open sources. However, the real use of the information is given by the implementation of three machine learning models used to perform sentiment analysis over this in-formation, in order to know the opinion of the adversary about certain topic and understand his motivation and, in this way, define proper cyber defense strategies. Fina-lly, some challenges related to the application of OSINT techniques are identified and described regarding its use by state security agencie

    Sustainable development goals (SDG) incorporate multiple dimensions to measure the progress made by nations in consolidating their economic and human development. Consequently, the main objective of this study is to explore the structures of variation and covariation between the SDGs indicators interpreting and describing their current status by countries and regions of the world. This study assessed 40 SDG indicators reported by 125 countries in the 2021 Sustainable Development Report, using the HJ-Biplot multivariate technique, through which it is possible to analyze the existing relationships between indicators and countries in a multidimensional way. The results indicate that the global North countries currently display solid sustainability characteristics that favor economic growth, though more work is required to protect the environment and promote responsible production and consumption. On the other hand, the countries of the global South with less purchasing power must still work on policies and strategies to promote the health and well-being of their populations, enable access to essential household services (water, sanitation, electricity, and internet, among others), and promote equality

    A Metal-Organic Framework (MOF), iron-benzenetricarboxylate (Fe(BTC)), has been studied for the adsorptive removal of azo-dye Orange II from aqueous solutions, where the effect of various parameters was tested and isotherm and kinetic models were suggested. The adsorption capacities of Fe(BTC) were much higher than those of an activated carbon. The experimental data can be best described by the Langmuir isotherm model (R2 > 0.997) and revealed the ability of Fe(BTC) to adsorb 435 mg of Orange II per gram of adsorbent at the optimal conditions. The kinetics of Orange II adsorption followed a pseudo-second-order kinetic model, indicating the coexistence of physisorption and chemisorption, with intra-particle diffusion being the rate controlling step. The thermodynamic study revealed that the adsorption of Orange II was feasible, spontaneous and exothermic process (-25.53 kJ·mol-1). The high recovery of the dye showed that Fe(BTC) can be employed as an effective and reusable adsorbent for the removal of Orange II from aqueous solutions and showed the economic interest of this adsorbent material for environmental purposes. © 2014 by the authors.The authors thank Autonomous Metropolitan University for its financial support to the project “Synthesis, modification and application of porous solid materials to sorption phenomena and catalysis”.
