Conformación de 11/50 Ensamble: Sistematización de una experiencia creativa
(Universidad Distrital Francisco José de Caldas) Ángel Garzón, Sara Marcela; Arroyave, Myriam
The present work is an analysis and critical interpretation of the experience of forming the contemporary music ensemble 11/50 Ensamble. This is carried out through the development of the methodological proposal: the Systematization of experiences, a new way of approaching the creative process. The work describes the analysis of the factors, circumstances, situations, and agents that intervene in the process of collective musical creation, within the scope of contemporary academic music and especially the musical moment of the 20th century called indeterminism. Based on the above, the concepts of creator, interpreter, and audience were redefined, and the work Recorriendo el Pensamiento de Sara Angel (2012) was staged and performed for the development of the socialization of results. The results of this work show the importance of carrying out an interpretation and critical reflection on musical work, in order to improve practice based on its theorization. All of the above with the purpose of motivating the local musician to participate actively in their current social, political and cultural environment in a society in which there is access to a great variety of information.
Caracterización florística y estructural de la vegetación en la Reserva Natural de la Sociedad Civil El Diluvio (Villapinzón, Cundinamarca)
(Universidad Distrital Francisco José de Caldas) Mora Porras, Angie Carolina; Cortazar Pérez, Ingrid Alejandra; Avella Muñoz, Edgar Andrés
The high mountain faces a serious crisis due to the transformation of its natural cover, particularly in the eastern sector, where 28% of the territory presents conflicts due to land overuse. The situation is especially critical in the Bogotá River basin, where pressure from agricultural activities, mainly potato cultivation, and cattle ranching have generated a 90% increase in ecosystem fragmentation between 2002 and 2018. In this context, the El Diluvio Civil Society Nature Reserve, located in Villapinzón, is a strategic area within the high mountain ecosystems due to its transition zones between the high Andean forest and the páramo. As part of the Chingaza- Sumapaz- Guerrero- Guacheneque and Cerros Orientales conservation corridor, the reserve plays a crucial role in water regulation and ecological connectivity, ecosystem services that benefit nearly 9 million inhabitants who depend directly on the resources of this watershed.
The methodology was structured in three phases: preparation, field and systematization. In the preparation phase, secondary information was collected and reconnaissance surveys were carried out to define 30 plots distributed in three strata (forest, grassland and grassland-herbaceous). The plots were 100 m² in size for the forest stratum, 50 m² for the grassland stratum and 50 m² for the herbaceous and grassland-frailejonal stratum. During the field phase, the plots were delimited and structural vegetation data, botanical and soil samples were collected using georeferencing and measurement tools. Finally, in the systematization phase, climatic data were analyzed, soil samples were processed in the laboratory, botanical collections were identified in the UDBC herbarium and vegetation was classified using phytosociological approaches, complemented with ecological indices to characterize the structure of the vegetation units found.
The syntaxonomic study of the vegetation in the El Diluvio Civil Society Nature Reserve identified four plant associations, including two new associations for the Eastern Cordillera: Clusio multiflorae-Weinmannietum tomentosae and Linochilo rosmarinifolii-Vaccinietum floribundi. In addition, the presence of the alliance Espeletio murilloi-Chusqueetum tessellatae, documented in the páramo of La Rusia in Duitama, was confirmed, and an undetermined alliance was described with two plant communities: Espeletiopsis rabanalensis with Aragoa cleefii and Espeletia barclayana with Scrobicaria ilicifolia.
The structural and physiognomic analysis showed a distribution pattern determined by environmental factors, where the Clusio multiflorae-Weinmannietum tomentosae forests develop on poorly exposed slopes with deep soils rich in organic matter, while the Linochilo rosmarinifolii-Vaccinietum floribundi grassland is established on rocky and well-drained soils. In the pajonal-frailejonal, a sequence from steep areas to low slope areas with poorly drained soils was identified, which influences species composition. The unusual presence of forests at higher altitudes suggests ongoing regeneration processes, probably influenced by anthropogenic intervention. The identification of these patterns provides a fundamental basis for the development of ecological restoration strategies in the upper Bogotá river basin, contributing to the conservation of key ecosystems in the region.
Propuesta de actualización de valores catastrales basado en capitalización de renta usando modelos de aprendizaje automático: Interpretación de áreas cultivadas y estimación de valor de suelo para cultivo de palma de aceite en la vereda Llano Grande San Martín - Meta
(Universidad Distrital Francisco José de Caldas) Forero Porras, Sebastián; Vergara Dueñas, Andrés Sebastián; Torres Colmenares, Oscar Fernando
This research proposes a system to determine cadastral values through rent capitalization using machine learning models and satellite image processing. It focuses on the identification of oil palm crops located in the Llano Grande district in San Martin, Meta (Colombia), to calculate the land value and propose a system that helps to improve the accuracy of the cadastral valuation. Neural networks and satellite images are used to determine the area of the crop and its profitability. The results show that this approach manages to reduce biases, considering the current land use, providing information that contributes to territorial planning and multipurpose cadaster management.
Zonas homogéneas físicas y geoeconómicas del suelo de los predios del área de influencia de la segunda línea del metro de Bogotá (L2MB) para la tercera estación (E3)
(Universidad Distrital Francisco José de Caldas) Gutiérrez Robayo, Libardo; Pérez Carvajal, Edwin Robert
This work focuses on the generation of reference values in 2024 within the zone of influence of the Second Line of the Bogotá Metro (L2MB), specifically for Station 3, after the announcement of its award and construction. This analysis will allow, in the future, to evaluate the impact on real estate values due to the public work once it is completed.
In order to understand this phenomenon, it was necessary to rely on different approaches to the theoretical bases and current background through similar studies developed in cities in other countries where projects of this magnitude have already been executed, and in the case of Colombia, the impact generated by the Medellin Metro inaugurated in 1995.
Experience tells us that in infrastructure projects of this magnitude there have been increases in land values that are attributed to various factors, such as greater accessibility to different areas of the city, improvement in the quality of the urban environment and the perception of greater value of the areas near Mass Transportation Systems such as the Metro.
Plan de gestión de proyectos para el abandono definitivo de un pozo de hidrocarburos, Colombia
(Universidad Distrital Francisco José de Caldas) Caro Rojas, Fabián Enrique; Velandia Durán, Edder Alexander
The project addressed project management for the final abandonment of a hydrocarbon well in Colombia. Its main objective was to design a management plan to optimize resources and comply with government regulations, while minimizing operational, environmental and safety risks. The project included an analysis of the market, demand and supply of well abandonment services, and considered the social, legal and environmental implications.
The results showed that a planning, based on the logical framework methodology, allowed the identification of the main actors involved and the associated risks, as well as the analytical structure of the project for its correct execution. Two alternatives for management were presented: implementing an internal structure or contracting an external consultancy. The conclusions show that the implementation of an efficient management plan not only contributed to the reduction of cost overruns, but also improved the company's credibility and competitiveness in the Colombian energy sector. In addition, it was shown that the project has the potential to contribute to the training of new researchers and the strengthening of project management research in Colombia.
