    Adopción de buenas prácticas en seguridad de la información enfocado en ambientes OT
    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Moreno, Diego Armando; López, Luis Carlos; Moreno, Diego Alejandro; Serrato Rodriguez, Yenny Isabel
    The advantages of the use of technology, digitization and connectivity currently in the OT operational industry are quite significant, but at the same time the possibility of suffering a cyber attack increases due to the greater exposure of the intrusion surface. In addition to this, currently industries of all kinds (electricity, gas, manufacturing, health, etc.) are targets of cybercriminals due to the great impact that the materialization of a risk can have on the company and/or society, the result of which is would have consequences such as: economic, reputational, environmental, to the integrity of people, etc.).

    Aeronaves no tripuladas como herramienta para el análisis de áreas no preparadas de aterrizaje en operaciones helicoportadas
    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Fuentes Mojica, Gerardo Alcides; Rodriguez Barón, Iván Felipe
    Air operations of helicopters in unprepared areas are a constant in the hydrocarbon environment, due to the remoteness of facilities and the challenging access to infrastructure caused by the difficult Colombian geography and its limited access routes. The lack of suitable heliport services in these areas forces a constant reliance on the use of unprepared areas to carry out aerial operations for the movement of personnel and cargo in helicopters, which are vital for supplying and maintaining the infrastructure related to the hydrocarbon industry. An additional factor in these high-risk operations is the limited time available to conduct a proper analysis of the terrain and various obstacles. This is why it is necessary for the planning team to present this information in a clear, objective, and precise manner to contribute to the decision-making of the crews. This allows for a precise assessment of the risks associated with operations in unprepared areas; otherwise, there would be inadequate management, resulting in uninformed decisions and a lack of appropriate safety and prevention measures that could lead to an accident. The proposed solution to address the challenge of helicopter air operations in unprepared areas lies in the strategic implementation of drone technology as the main tool for taking measures and identifying obstacles. This involves employing various image processing techniques such as photogrammetry and structure inspection. The product obtained will be presented to the crews and personnel involved in the operation briefing to enhance aviation safety.

    The land is a natural resource that has existed since time immemorial, it is therefore not a good that is produced or manufactured, which is why, since it is a pre-existing commodity, its quantification, weighting or determination of value becomes complex, for This is essential to have methodologies that explain the value of this resource. It should be noted that the land, like most of the assets that make up a property, are real estate (buildings, crops, plantations, among others) that are part of the asset to its owner. In a negotiation process under the market standard, the value of the asset will be the result of the independent analysis obtained to the land and the construction if it exists and part of the classic model. However, in these processes it often appears within the inventory of goods to be acquired by the buyer, environmental goods such as ecosystems which do not have adequate methodologies that correspond to the valuation principles of a negotiation, a situation that distorts the final value and that In the end, by not incorporating the value into this variable, the equity of its owners decreases, as does the environmental asset of the company as a whole. This project is formulated with the purpose of demonstrating the need to incorporate into the classic real estate valuation model, a variable that is considered independent from those included conventionally. In property negotiation processes for different projects that involve voluntary alienation or expropriation, and in areas that, due to their environmental wealth or geographical location, their intervention is necessary, what is the effect of not incorporating the environmental variable into an appraisal? Taking into account that an ecosystem from an environmental point of view is a biological system made up of living beings and the natural environment in which they live, how can a reference value be established to be incorporated into a valuation report?

    Análisis con Machine Learning de Peticiones Externas (PQRS) del Servicio Nacional de Aprendizaje - SENA para mitigación de incumplimientos normativos
    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Ayala Alfonso, Yésica Patricia; Durán Ramírez,Julio Mario; González Martínez., Edwin Fernando
    The National Learning Service - SENA receives Petitions, Complaints, Claims, Suggestions, Denunciations, Acknowledgments, Congratulations and Guardianship Actions (PQRS) that must be managed to guarantee a timely response to citizens who request the solution to their requirement; additionally, it must ensure the follow-up and compliance with the regulations that regulate the management of PQRS in Colombia, as well as automating processes that are currently carried out manually. For this reason, the purpose of this project is to analyze with Machine Learning models the PQRS received by SENA, which allow mitigating the risk of materializing regulatory breaches and manage to resolve the PQRS in a timely manner for the public. For this, the SEMMA methodology is used, being the more appropriate for the analysis of large databases. It should be noted that language tools were used of Python and R programming to execute and apply the analysis of the PQRS, obtaining conclusive results and satisfactory about the Machine Learning models chosen to predict the possible violation of rights of citizenship; therefore, with these results, it is considered necessary to suggest the implementation of the models executed before SENA.

    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Castillo Soto, Diana Carolina; Romero Ospina, Manuel Francisco
    Based on the application of multivariate analysis and cluster analysis, the article argues that there is an association between the characteristics of Colombians who emigrate and stand out as residents and different countries in the world. This article shows which are the main trends and similarities of the population given the destination country, it is established in this article that the migratory case of Colombians to Venezuela is unique in the migratory history of Colombia, it has no similarity with the characteristics or situations of migrants with other destinations and despite the fact that it is the oldest destination, consular records show that as of April 2021 it is the country that has received the most Colombians. high, the characteristics of educational level and marital status are tangentially distant from those shown by the population that registers as resident in Venezuela.

    Análisis de datos de vuelo durante la aproximación final de aeronaves categoría commuter
    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Rodríguez Villamil, Juliám; Fonseca Gomez, Lida Rubiela
    The development of this research was in order to identify possible trends to be carried out later, consider the possibility of generating recommendations on safety to operators, showing from some of the most basic concepts in aviation to the importance of implementation and maintenance of FDA flight data analysis programs, which can be costly at first, but the benefits obtained in the medium and long term can be incalculable, taking into account the effects that can occur due to a chain of errors not identified in air operations. For this we carry out a statistical analysis that in the future allows us to mitigate risks based on real data from the operation. For the statistical analysis, the R and SSPS software were used, which allowed us to identify deviations in the operation. Likewise, it will be identified that although the FDA programs can become a very useful tool at the local level, no guidelines were found to carry out an adequate implementation, making it necessary to refer to foreign advisory circulars to obtain an adequate guide on FDA matters.

    Análisis de elementos de tierras raras en cenizas de Carbón a través de técnicas de aprendizaje automático no supervisado (CLUSTERING)
    (Fundación Universitaria Los Libertadores. Sede Bogotá., ) Díaz Moreno, Héctor Felipe; Gonzalez Martinez, Edwin Fernando
    Coal ash is a byproduct of coal combustion in power plants, which contains a variety of chemical elements among which are the rare earth elements and given the special characteristics that the starting material COAL possesses, there is a high probability of being found in appreciable quantities. Colombia, as the main producer of Coal in Latin America and 5 in the world, presents as a good alternative in their search and since over the years they have been accumulating ashes in the surroundings of the thermal power plants product of the combustion for the generation of electricity and are not They have given other uses different from those traditionally established. A pile of ashes is characterized within a ash yard in a thermoelectric plant in Colombia, obtaining the amount of ETRs by ICP-MS and the elements older by XRF. To the results obtained from the study, the methodology of exploration and treatment of SEMM data. Clustering algorithms such as K-means, Hierarchical Clustering, and DbScan are used to explore segregation patterns in the data. Metrics such as the Silhouette coefficient, the sum of squares, the Calinski-Harabasz and Davies Bouldin partition criteria to assess the quality of the clusters obtained. Besides, Statistical tests are performed to determine the significance of the aggregates obtained. They are found for 3 to 4 segregations depending on the unsupervised algorithm used, showing that the groupings obtained have good quality in terms of between-group variance and these values ​​indicate that the groups are well separated and they have a high internal cohesion and are homogeneous, separated and cohesive within the groups, validating the segregation quality explaining more than 80% of the variability of the data. Since three to four groups comply with being the best segmentation obtained taking into account this result coal ashes can be treated differentially during the processes of extraction and/or benefit of the earth elements in this type or another of by-products of coal combustion showing a field of application still to be explored and with good growth prospect.
