    Análisis de los riesgos materializados por la pandemia del Covid-19 y sus impactos en bares y discotecas de la ciudad de Medellín
    (Universidad EAFIT, 2022) Gutiérrez Buitrago, Dione Alejandra; Montoya Correa, Sebastián; Gómez Salazar, Elkin Arcesio
    The main objective of this study is to analyze the financial impacts of the risks materialized by the COVID-19 pandemic in bars and clubs classified as small businesses in the city of Medellín. For this, the identification of the risks and their financial impacts was carried out through a mixed methodology with the implementation of interviews with the main representatives of the guild and application of surveys aimed at the owners or managers of these establishments. The results obtained allowed to know the economic losses presented by the respondents, which served as a starting point to make the projection of the VaR (Value at Risk) of the sector at the local level and its extrapolation at the national level, making visible the financial reality and the capacity that the sector has in order to make its operation sustainable. This research may serve to strengthen government public policies and relief programs for this guild, opening lines of research to give continuity to risk management such as the monitoring of these and the effectiveness of the controls implemented.

    Seismic risk assessment for the residential buildings of the major three cities in Colombia: Bogotá, Medellín, and Cali
    (EARTHQUAKE ENGINEERING RESEARCH INST, 2020-01-01) Acevedo A.B.; Yepes-Estrada C.; González D.; Silva V.; Mora M.; Arcila M.; Posada G.; Mecánica Aplicada
    This study presents a seismic risk assessment and a set of earthquake scenarios for the residential building stock of the three largest metropolitan centers of Colombia: Bogotá, Medellín and Cali (with 8.0, 2.5, and 2.4 million inhabitants, respectively). A uniform methodology was followed for the development of the seismic hazard, vulnerability, and exposure models, thus allowing a direct comparison between the seismic risk of the different cities. Risk metrics such as exceedance probability curves and average annual losses were computed for each city. The earthquake scenarios were selected considering events whose direct economic impact is similar to the aggregated loss for a probability of exceedance of 10% in 50 years. Results show a higher mean aggregate loss ratio for Cali and similar mean aggregate loss ratios for Bogotá and Medellín. All of the models used in this study are openly accessible, enabling risk modelers, engineers, and stakeholders to explore them for disaster risk management. © The Author(s) 2020.

    Understanding epidemics from mathematical models: Details of the 2010 dengue epidemic in Bello (Antioquia, Colombia)
    (Elsevier Inc., 2017-03-01) Lizarralde-Bejarano, D.P.; Arboleda-Sánchez, S.; Puerta-Yepes, M.E.; Lizarralde-Bejarano, D.P.; Arboleda-Sánchez, S.; Puerta-Yepes, M.E.; Universidad EAFIT. Departamento de Ciencias; Matemáticas y Aplicaciones
    Dengue is the most threatening vector-borne viral disease in Colombia. At the moment, there is no treatment or vaccine available for its control or prevention; therefore, the main measure is to exert control over mosquito population. To reduce the economic impact of control measures, it is important to focus on specific characteristics related to local dengue epidemiology at the local level, and know the main factors involved in an epidemic. To this end, we used a mathematical model based on ordinary differential equations and experimental data regarding mosquito populations from Bello (Antioquia, Colombia) to simulate the epidemic occurred in 2010. The results showed that the parameters to which the incidence of dengue cases are most sensitive are the biting and mortality rates of adult mosquitoes as well as the virus transmission probabilities. Finally, we found that the Basic Reproductive Number (R0) of this epidemic was between 1.5 and 2.7, with an infection force (?) of 0.061, meaning that R0 values slightly above one are sufficient to result in a significant dengue outbreak in this region. © 2016 Elsevier Inc.
