Formative research contributions to the development of Risaralda

Es importante establecer y visibilizar a los estudiantes los beneficios relacionados con la formación en investigación, dentro de los cuales encontramos el fortalecimiento de las capacidades de liderazgo así como el compromiso activo y las experiencias en independencia y colaboración. Así mismo, la formación integral hacia una mayor apreciación del valor de la literatura disciplinaria, generando de esta manera habilidades de pensamiento crítico, indagación y análisis. Además, esto permite forjar la confianza en sí mismo para presentar las propias ideas a la comunidad, permitiendo al estudiante la preparación de futuras actividades académicas, incluidos estudios de posgrado. La investigación formativa tiene como propósito la difusión de la información existente y permitir que el estudiante la integre como conocimientos, considerándolo como un aprendizaje permanente y necesario. Uno de los principales problemas que debe enfrentar la investigación formativa es el número de docentes con las capacidades necesarias para generar en el estudiante capacidades investigativas, exigiendo al profesor universitario adoptar una actitud contraria al objeto de enseñanza, generando un carácter complejo y dinámico del conocimiento.CONTENTS RETOS DE LA INVESTIGACIÓN EN PREGRADO..................................................5 CHALLENGES OF UNDERGRADUATE RESEARCH.............................................9 German Oved Acevedo Osorio CHAPTER 1 HEALTH AND SPORTS SCIENCES FACTORS ASSOCIATED WITH EXACERBATIONS OR CRISIS EVENTS OF CHRONIC NON COMMUNICABLE DISEASES.........................13 Giovanni García Castro, Sandra Milena Bedoya Gaviria, Isabela Patiño Pulgarín y Valentina Valencia Flórez ORAL ANTICOAGULATION IN PATIENTS WITH NON-VALVULAR ATRIAL FIBRILLATION IN A UNIVERSITY HOSPITAL IN COLOMBIA.....................................................................................................29 María Leonor Galindo Márquez, Adrian Giraldo Diaconeasa, Juan Darío Franco Ramírez y Eduardo Ramírez Vallejo PERFORMANCE IN INITIAL TRAUMAASSESSMENT OF EMERGENCY TEAMS FROM PREHOSPITAL CARE TEAMS..................43 Giovanni García Castro, Yamileth Estrada Berrio, Manuela Aguirre Torres e Isabella Díaz Leal ACADEMIC TRAINING AND WORKING CONDITIONS OF NURSING PROFESSIONALS IN PEREIRA - RISARALDA 2020.....................55 Miguel Ángel Gómez Puerta, Laura Isabel Orozco Santamaría, Alexandra Villa Patiño y Gladys Judith Basto Hernández EFFECTS OF DYNAMIC TAPE WITH ANTI-VALGUS APPLICATION ON VERTICAL JUMP PERFORMANCE IN PHYSICALLY ACTIVE WOMEN: A CASE STUDY ..........................................73 María Camila Arias Castro, Alejandro Gómez Rodas y Ángela María Cifuentes Ríos PROPOSAL OF CARE FOR DIAGNOSTIC PREVALENT NURSES IN AN EMERGENCY DEPARTMENT................................................................89 Tatiana Restrepo Pérez, Jessica Viviana Ríos Uribe, Anyi Daniela Lemos Córdoba, Anyi Katherine Mapura Benjumea and Mónica Margarita Barón Castro FACTORS AND CONCEPTS ASSOCIATED WITH THE INITIATION OF CIGARETTE CONSUMPTION IN UNIVERSITY STUDENTS OF PEREIRA, COLOMBIA ............................................................................... 113 Giovanni García Castro, Claudia Milena Bernal Parra, Natalia Cardona Arroyave, Brahiam Stiven Moreno Bustamante y Daniela Ospina Sierra CHAPTER 2 ECONOMIC, ADMINISTRATIVE AND ACCOUNTING SCIENCES TECHNICAL-FINANCIAL EVALUATION OF BEAN (PHASEOLUS VULGARIS) VARIETY CARGAMANTO IN THE VILLAGE OF THE MUNICIPALITY OF SIBUNDOY IN THE DEPARTMENT OF PUTUMAYO ................................................................................................ 131 Adriana María Cuervo Rubio, Alejandra Arango Baranza IMPLEMENTATION OF THE NIF IN MICRO-ENTERPRISES OF PEREIRA CITY ............................................................................................ 151 Laura Cortes Correa y Nataly Andrea Gutiérrez STRATEGIC FRAMEWORK FOR SUSTAINABLE PRODUCTION IN COLOMBIA................................................................................................... 163 Paulina Murillo Gómez, Manuela Ramírez Osorio, Laura Juliana Rodríguez Henao, Lindy Neth Perea Mosquera, Isabel Redondo Ramírez SUSTAINABLE INNOVATION IN MANUFACTURING INDUSTRY........... 179 Mariana Buitrago Zuleta, Laura Juliana Rodríguez Henao, Lindy Neth Perea Mosquera y Marlen Isabel Redondo Ramírez CHAPTER 3 ARTS, HUMANITIES AND SOCIAL SCIENCES PERSONAL AND FAMILY CHANGES OF UNDERGRADUATE PSYCHOLOGY STUDENTS.

Measurement of CP violation parameters and polarisation fractions in Bs0→J/ψK‾∗0 {\mathrm{B}}_{\mathrm{s}}^0\to \mathrm{J}/\psi {\overline{\mathrm{K}}}^{\ast 0} decays

The first measurement of ${C\!P}$ asymmetries in the decay ${B_s^0\to J/\psi \overline{K}^{*}(892)^{0}}$ and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of $3.0\,fb^{-1}$ of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of $7$ and $8\,\mathrm{TeV}$. Together with constraints from ${B^0\to J/\psi \rho^0}$, the results are used to constrain additional contributions due to penguin diagrams in the ${C\!P}$-violating phase ${{\phi}_{s}}$, measured through ${B_s^0}$ decays to charmonium.The first measurement of CP asymmetries in the decay ${B}_s^0\to J/\psi {\overline{\mathrm{K}}}^{\ast }{(892)}^0$ and an updated measurement of its branching fraction and polarisation fractions are presented.

Evidence for the strangeness-changing weak decay Ξb−→Λb0π−\Xi_b^-\to\Lambda_b^0\pi^-

Using a $pp$ collision data sample corresponding to an integrated luminosity of 3.0~fb$^{-1}$, collected by the LHCb detector, we present the first search for the strangeness-changing weak decay $\Xi_b^-\to\Lambda_b^0\pi^-$. No $b$ hadron decay of this type has been seen before. A signal for this decay, corresponding to a significance of 3.2 standard deviations, is reported. The relative rate is measured to be ${{f_{\Xi_b^-}}\over{f_{\Lambda_b^0}}}{\cal{B}}(\Xi_b^-\to\Lambda_b^0\pi^-) = (5.7\pm1.8^{+0.8}_{-0.9})\times10^{-4}$, where $f_{\Xi_b^-}$ and $f_{\Lambda_b^0}$ are the $b\to\Xi_b^-$ and $b\to\Lambda_b^0$ fragmentation fractions, and ${\cal{B}}(\Xi_b^-\to\Lambda_b^0\pi^-)$ is the branching fraction. Assuming $f_{\Xi_b^-}/f_{\Lambda_b^0}$ is bounded between 0.1 and 0.3, the branching fraction ${\cal{B}}(\Xi_b^-\to\Lambda_b^0\pi^-)$ would lie in the range from $(0.57\pm0.21)\%$ to $(0.19\pm0.07)\%$.Using a pp collision data sample corresponding to an integrated luminosity of 3.0  fb-1, collected by the LHCb detector, we present the first search for the strangeness-changing weak decay Ξb-→Λb0π-.

Search for the rare decays B0→J/ψγB^{0}\to J/\psi \gamma and Bs0→J/ψγB^{0}_{s} \to J/\psi \gamma

A search for the rare decay of a $B^{0}$ or $B^{0}_{s}$ meson into the final state $J/\psi\gamma$ is performed, using data collected by the LHCb experiment in $pp$ collisions at $\sqrt{s}=7$ and $8$ TeV, corresponding to an integrated luminosity of 3 fb$^{-1}$.
