Tratamiento normativo al status de beligerancia y terrorismo dentro del conflicto armado en Colombia

For about 50 years there has been an armed conflict in Colombia, but recently acknowledged by the government, leaving as a result huge social gaps, economic and devastating consequences and noticeable cultural changes in the national imaginaries of life and development. Terms as belligerency, terrorism, and armed conflict are now part of our lexicon. The pretension for this research is to address the issue of the regulatory treatment given by Colombian legislation to the status of belligerence, terrorism and armed conflict without neglecting of course that in this regard, our regulations have adopted those from the International Law through the Constitutionality cluster.En Colombia desde hace aproximadamente cincuenta años ha tenido lugar un conflicto armado, recientemente reconocido por el gobierno, que ha dejado como resultado grandes brechas sociales, consecuencias económicas devastadoras y cambios culturales notables en los imaginarios nacionales de vida y desarrollo. Términos como beligerancia, terrorismo y conflicto armado, hacen parte ahora de nuestro léxico. Es entonces como desde esta investigación se pretende abordar el tratamiento que desde la normativa se le ha dado al status de beligerancia, terrorismo y conflicto armado en la legislación colombiana, sin dejar de lado, por supuesto, que nuestra reglamentación ha adoptado normativas al respecto desde el Derecho Internacional mediante el bloque de constitucionalidad

El SECOP II y su implementación en la gobernación del departamento de Caldas

El gobierno de Colombia fijó mediante el Documento Conpes 3249, la política pública a seguir en materia de contratación del Estado. Para ello, entre otros criterios, estableció la creación de un sistema electrónico de contratación que se concretó mediante la expedición del Decreto 3485 (2011), sistema al que se le denominó SECOP (Sistema electrónico para la contratación pública), y está compuesto por tres plataformas: la Tienda Virtual del Estado Colombiano, el Secop I y el SECOP II.Por lo anterior, el semillero de investigación Contratación Estatal del Programa de Derecho de la Universidad Católica Luis Amigó, sede Manizales, decidió realizar un análisis sobre la preparación e implementación del SECOP II en la Gobernación del departamento de Caldas, con el fin de determinar si tal entidad cuenta con un grado o nivel óptimo de preparación jurídica, tecnológica, de infraestructura y de talento humano que le permita poner en funcionamiento esta plataforma de acuerdo con los parámetros dados por Colombia Compra Eficiente (CCE) como ente administrador de dicho sistema.El resultado expuesto es producto de un proceso de investigación jurídico-dogmática que desarrollaron los autores en cinco (5) fases mediante la aplicación de un método mixto con enfoque empírico-analítico

Transmisión vertical de virus dengue en Aedes spp. (Diptera: Culicidae) en Medellín, Colombia

Dengue is the world’s most important arbovirus. It is transmitted by the bite of females Aedes spp. mosquitoes, which normally become infected by biting a viraemic host. There are, however, numerous studies that have identified vertical transmission as a rare yet important mechanism of vector infection. This study was conducted in order to quantify the occurrence of vertical transmission of dengue virus in Aedes mosquitoes collected by the Secretary of Health in Medellin, Colombia in 2016 (epidemic year) and 2017 (endemic year). Specimens were identified to species and tested for dengue in pools by RT-PCR. A total of 6,708 mosquitoes were collected; 96 % were Ae. aegypti, and 4 % were Ae. Albopictus. 294 of 2,211 pools tested were positive for dengue virus, and 50 of the positive pools were exclusively male mosquitoes. For both epidemic and the endemic years, vertical transmission was detected, though it was more frequent in 2016. Vertical transmission was observed in mosquitoes collected from all sectors of the city, without a distinct spatial pattern. Our results suggest that vertical transmission is a more frequent event with greater epidemiological relevance than previously estimated. Additional studies are required to verify the infectivity of the virus detected in male mosquitoes and to specify the role of vertical transmission in the incidence of dengue virus.El dengue es la arbovirosis más importante en salud pública. Es transmitido por la picadura de mosquitos hembras de Aedes spp., que se infectan de manera horizontal al ingerir sangre de una persona virémica. Sin embargo, numerosos estudios han identificado la transmisión vertical como otro mecanismo de infección vectorial. Con el propósito de analizar la ocurrencia de transmisión vertical del virus dengue por mosquitos Aedes, se recolectaron mosquitos adultos en viviendas y otras locaciones durante los levantamientos de índices entomológicos realizados por la Secretaría de Salud de Medellín en los años 2016 (epidémico) y 2017 (endémico). Los ejemplares se identificaron y conformaron pools para la detección viral por RT-PCR. En total se recolectaron 6.708 mosquitos, donde, el 96 % y 4 % correspondieron a Ae. aegypti y Ae. albopictus, respectivamente. De los 2.211 pools conformados, 294 resultaron positivos para virus dengue, y 50 de estos correspondieron exclusivamente a machos de Aedes spp. Tanto para el año epidémico como endémico, se registró transmisión vertical, pero fue más frecuente en el 2016. Se observó transmisión vertical en todos los sectores de la ciudad, sin un patrón definido. La presencia de machos Aedes spp. infectados naturalmente con virus dengue sugiere que la transmisión vertical es un evento más frecuente de lo que se consideraba, y podría comprender una mayor relevancia epidemiológica. Estudios adicionales para verificar la capacidad de infección del virus detectado en mosquitos machos y precisar el papel de la transmisión vertical en la incidencia de dengue se hacen necesarios

Evaluation and Performance of a Positive Airway Pressure Device (CPAP-AirFlife™): A Randomized Crossover Non-Inferiority Clinical Study in Normal Subjects

Background and Objectives: During the COVID-19, the demand for non-invasive ventilatory support equipment significantly increased. In response, a novel non-invasive ventilatory support model called CPAP-AirFlife™ was developed utilizing existing technologies. This model offers technological advantages, including an aerosol-controlled helmet suitable for high-risk environments such as ambulances. Additionally, it is cost-effective and does not require medical air, making it accessible for implementation in low-level hospitals, particularly in rural areas. This study aimed to assess the efficacy of CPAP-AirFlife™ by conducting a non-inferiority comparison with conventional ventilation equipment used in the Intensive Care Unit. Materials and Methods: A clinical study was conducted on normal subjects in a randomized and sequential manner. Parameters such as hemoglobin oxygen saturation by pulse oximetry, exhaled PCO2 levels, vital signs, and individual tolerance were compared between the CPAP-AirFlife™ and conventional equipment. The study population was described in terms of demographic characteristics and included in the analysis. Results: It was shown that the CPAP-AirFlife™ was not inferior to conventional equipment in terms of efficacy or tolerability. Hemoglobin oxygen saturation levels, exhaled PCO2 levels, vital signs, and individual tolerance did not significantly differ between the two models. Conclusions: The findings suggest that CPAP-AirFlife™ is a practical and cost-effective alternative for non-invasive ventilatory support. Its technological advantages, including the aerosol-controlled helmet, make it suitable for high-risk environments. The device’s accessibility and affordability make it a promising solution for implementation in low-level hospitals, particularly in rural areas. This study supports using CPAP-AirFlife™ as a practical option for non-invasive ventilatory support, providing a valuable contribution to respiratory care during the COVID-19 pandemic and beyond

Research, Innovation and Extension to the service to society, in the framework of the Sixth Conference on Social Appropriation of Knowledge (SAK)

Annually, the Technological University of Pereira has been carrying out some events in the line of Social Appropriation of Knowledge. This has been done through the research, innovation, and extension Vice Rectory, moreover, these sessions are framed within the institutional objective: “Define and direct the guidelines for the institutional research that strengthen the research groups and the Seedbeds, through the formation of researchers, the development of science, technology, and innovation projects or programs, as well as the generation of networks and strategic partnerships that contribute to the creation and appropriation of knowledge for the society”. Therefore, the 6th Social Appropriation of Knowledge event took place under the title of “The research, Innovation, and Extension at the service of society” which was constituted as an academic and institutional opportunity where the results of the research projects from the last 5 years were published. The results of this event revealed, once again, the high academic level in investigation development at the university. There were 11 articles divided into 6 fields: Health, Engineering, Technology, Education, Industrial Technology, and Art, in which the results obtained by the research projects from the investigation groups were shown, promoting a knowledge exchange from their authors whose intellectual formation is diverse. With this publication, as part of a permanent effort to socialize the knowledge, the university promotes the circulation of its professors, students, and general community voices, having in mind that knowledge must be transferred through different channels, strengthening the academy and society in general, according to the institutional mission that invites us to incentivize a research culture in the university community.Presentation........................................................................................................... 5 Chapter 1.
