O marketing mútuo como estratégia emergente: Caso de batata durante a pandemia de Covid 2019
Get PDFThis document presents the potato chain's main obstacles in Colombia during the pandemic and analyses one of many solutions applied. The mechanisms of collaboration in marketing are studied from a biological metaphor as an emerging strategy to solve the distribution problems of the potato chain. The virus emergence stands out as a deconstructive event, in which, in addition to deliberate strategies, an emerging one is required to solve the economic problems derived from the pandemic situation. Finally, this work identifies the emerging elements that favored this situation and proposes some factors to strengthen mutualist marketing as an alternative in a deconstruction event.En este documento se presentan los principales inconvenientes que tuvo la cadena de la papa en Colombia durante la pandemia y se analiza una de las soluciones aplicadas. Se estudian los mecanismos de colaboración en marketing desde la metáfora biológica, como estrategia emergente para solucionar los problemas de distribución de la cadena de la papa. Se destaca el surgimiento del virus como un evento deconstructor, en el que, además de las estrategias deliberadas, se requiere de otra emergente para solucionar los problemas económicos y de salud derivados de la situación de pandemia.

El Uso De La Voz Propia Y De La Voz Ajena En La Escritura De Contenidos Educativos Virtuales: Un Análisis Basado En Corpus
Get PDFThis paper examines, from the dialogism perspective, the use of one’s own and others’ voices present in three types of virtual learning objects —textual, sonorous, and audiovisual— that are part of the “Science, Technology and Society” course of the virtual master’s degree in Science, Technology and Innovation of the University of Antioquia, Colombia. The methodology used was corpus-based analysis following two predetermined categories: citations, and positioning marks. It is concluded that the corpus has a polyphony evidenced, for the most part, through reformulation and support citations, and an emphasis on subjectivity where the first person plural predominates, findings that can be correlated with the configuration of discursive behaviors influenced by the multimodal format of virtual objects and its pedagogical intentionality, and that reinforce the importance of intertextuality as a fundamental characteristic for the development of virtual and dialogical educational resources.Este artículo examina, desde el principio dialógico, el uso de las voces propias y ajenas presentes en tres tipos de contenidos educativos virtuales —textuales, sonoros y audiovisuales— que hacen parte del curso “Ciencia, Tecnología y Sociedad” de la Maestría Virtual en Ciencia, Tecnología e Innovación de la Universidad de Antioquia, Colombia. La metodología utilizada fue el análisis basado en corpus, teniendo en cuenta dos categorías predeterminadas: las citas y las marcas de posicionamiento. Se concluye que el corpus posee una polifonía que se evidencia, en su mayoría, a través de citas de reformulación y de apoyo, y un énfasis de subjetividad donde predomina la primera persona en plural, hallazgos que pueden correlacionarse con la configuración de conductas discursivas influenciadas por el formato multimodal de los contenidos virtuales y su intencionalidad pedagógica, y que refuerzan la importancia de la intertextualidad como característica fundamental para el desarrollo de recursos educativos dialógico

Análisis comparativo en la respuesta lineal de sistemas estructurales muro-pórtico representativos de Bucaramanga incorporando interacción suelo estructura
Get PDFThis paper evaluates the influence of Soil-Structure Interaction (SSI) on the linear structural response of regular wall-frame systems representative of Bucaramanga-Colombia using the substructure approach proposed by Winkler. Information was collected from existing local systems study using official databases. Using the 22 factorial design of experiments, nine artificial buildings were created with different soil types and number of floors. These buildings were designed and detailed under the fixed base idealization, following the local seismic-resistant regulations. Analyses were carried out including and excluding the ISE. The results revealed that the ISE had a significant influence on the linear response of structures located a high seismic hazard zone, presenting variation in the fundamental period, change in the modal response, increase in drifts and decrease in the base shear. In addition, it was found that it also affects the analysis method for the design.El presente artículo evalúo la influencia de la Interacción Suelo – Estructura (ISE) en la respuesta estructural lineal de sistemas muro-pórtico regulares representativos de Bucaramanga-Colombia utilizando el enfoque de subestructura propuesto por Winkler.

Medición de parámetros de signos vitales para emisión de alertas móviles
Get PDFone of the main concerns of people, especially the elderly or minors in this time of pandemic, is how to know their immediate state of health. A key indicator for this is reported by vital signs parameters such as temperature, heart rate and oxygenation; currently, wearable devices such as smart watches or bands, allow such monitoring by connecting to a cell phone; however, many users are unaware or fail to achieve the proper interpretation of such reports. For this reason, in addition to monitoring vital signs, the objective of this proposed system is to issue alerts that are sent automatically, not only to the user of the device, but also to a companion via text message whenever any of these parameters is outside the normal allowed range. This is achieved with a user categorization model supported by a system of rules that describes the normal allowed ranges, establishing criteria for issuing alerts. The main benefit of the proposed system is to have specific information in real time, of a body parameter that allows warning of an altered state of health, which is useful as information for making medical decisions, but can also be an important input data to identify an individual with possible risk of contagion of a disease, useful information in a pandemicUna preocupación en las personas, consiste en cómo conocer su inmediato estado de salud. Un indicador clave para ello, lo reportan los parámetros de signos vitales: temperatura, frecuencia cardíaca y oxigenación; Los dispositivos wearables, permiten ese monitoreo mediante conexión con un móvil; sin embargo, muchos usuarios desconocen o no logran la interpretación adecuada de tales reportes. Por esta razón, además de monitorear automáticamente los signos vitales (en periodos determinados de tiempo), el objetivo del sistema propuesto, consiste en emitir alertas que se envían automáticamente, no solo al usuario del dispositivo, sino también a un acompañante mediante mensaje de texto, cada vez que alguno de estos parámetros se encuentra fuera del rango normal permitido. Esto se logra con un modelo de categorización de usuarios soportado por un sistema de reglas que describe los rangos normales, estableciendo criterios para emitir las alertas. El beneficio principal del sistema propuesto, es tener información específica y en tiempo real, de un parámetro corporal permitiendo advertir un estado alterado de salud, insumo importante, para tomar decisiones médicas.
