RESUMENSe analiza crítica y reflexivamente los paradigmas en investigación desde la polémica cualitativa y cuantitativa y su relación con la evolución de la investigación en enfermería. De esta manera se presentan las diferencias entre los enfoques, se identifican los problemas de investigación en enfermería en el marco de los paradigmas; finalmente se plantean alternativas y reflexiones para potenciar la investigación en enfermeria. El supuesto que subyace a través del artículo es que el paradigma cualitativo no presenta mayor frecuencia de uso en investigaciones en enfermería, debido a la deficiencia en el conocimiento de dicho enfoque y la inadecuada inclusión de ambos enfoques en el proceso enseñanza/aprendizaje desde el diseño curricular; sin embargo, se categoriza en la importancia de ambos paradigmas dependiendo del objeto de investigación y la visión del investigador.Palabras claves: Investigación, enfermería, paradigmas, triangulación. ABSTRACTParadigms in research are critically and reflexively analyzed since a qualitative and quantitative polemic point of view, and their relationship with the evolution of the nursing research, likely the differences are presented, among the focuses, the investigation problems are identified in Nursing in the framework of the paradigms; finally alternatives and reflections regarding nursing research are presented. The supposition that underlies through the article is that the qualitative paradigm does not present bigger use frequency in nursing investigations, due to the deficiency in the knowledge of this focus and the inadequate inclusion of both focuses in the process teaching/learning from the curricular design; however, it is categorized in the importance of both paradigms depending on the investigation object and the investigator's vision.

Recepción INTRODUCCIÓNEl propósito en este trabajo es realizar análi-sis crítico y reflexivo de los paradigmas y su relación con la investigación en enfermería. Inicialmente se aborda conceptos y generalidades sobre paradigmas y antecedentes históricos de éstos. Luego se presentan las especificidades y diferencias de los enfoques positivista cuantitativo y del sustantivista cualitativo. Se continúa con la evolución histórica de la investigación en enfermería, los paradigmas y los problemas encontrados en la investigación de enfermería, en el marco de los paradigmas, alternativas y reflexiones para potenciar la investigación en enfermería. Finalmente se presentan las conclusiones.
Objective: To understand fear of death and its relationship with emotional intelligence and other variables in nursing students in the last years of study. Methods: A descriptive and correlational study. Students (n = 188) responded to a questionnaire about: socio-cultural characteristics; Fear of Death and Emotional Intelligence Scales. Results: We obtained a measure of medium to high for fear of death (x = 3.35) and also the emotional perception component was positively correlated with the fear of death, while understanding and emotional regulation were negatively correlated with fear of death. The higher scores for fear of death were associated with the female gender, with lower levels of courses, and the perception of lower academic preparation on the subject. Conclusions: High levels of emotional intelligence, associated with less fear of death, provides evidence for the necessity of developing emotional skills in students facing transcendent situations and the unknown, such as death and the dying process. Keywords: Attitude to death; Fear; Emotional intelligence; Students, nursing resumen Objetivo: Conocer el miedo a la muerte y su relación con la inteligencia emocional y otras variables en estudiantes de enfermería de los últimos años de estudio. Métodos: Estudio descriptivo y correlacional. Los estudiantes (n=188) respondieron a un cuestionario sobre: características socioculturales; Escalas de Miedo a la Muerte y de Inteligencia Emocional. Resultados: Se obtuvo un promedio medio-alto en miedo a la muerte (3,35). La percepción emocional se correlacionó positivamente con miedo a la muerte, mientras que la comprensión y la regulación emocional se correlacionaron negativamente con el miedo a la muerte. Las puntuaciones más altas de miedo a la muerte se asociaron con el sexo femenino, con los niveles inferiores de los cursos y con la percepción de menor preparación académica en el tema. Conclusiones: Los niveles altos de inteligencia emocional, se asociaron con menos miedo a la muerte, lo que evidencia la necesidad de desarrollar en los estudiantes habilidades emocionales frente a situaciones trascendentales y desconocidas, como son la muerte y el proceso de morir. Descriptores: Actitud frente a la muerte; Miedo; Inteligencia emocional; Estudiantes de enfermería resumo Objetivo: Conhecer o medo da morte e sua relação com a inteligência emocional e outras variáveis em estudantes de enfermagem dos últimos anos de estudo. Métodos: Estudo descritivo e correlacional. Os estudantes (n=188) responderam a um questionário sobre: características socioculturais; Escalas de Medo da Morte e de Inteligência Emocional. Resultados: Obteve-se uma medida de médio para alto em medo da morte (x=3,35) e também o componente percepção emocional se correlacionou positivamente com o medo da morte, enquanto a compreensão e regulação emocional se correlacionaram negativamente com o medo da morte. As pontuações mais altas de medo da morte associaram-se com o gênero feminino, com os niveis inferiores dos cursos e com a percepção...
Multimedia video streaming is the most used data consumption service on the Internet. Maintaining a data flow rate that provides the best video quality possible without overflowing the pipeline is challenging. Dynamic Adaptive Streaming over HTTP (DASH) is a commonly used protocol that sends video data in small packages called chunks. However, this technique can lead to video buffering issues and video pausing due to an empty video buffer. Adaptive Scalable Video Streaming (ASViS) is a more versatile protocol that uses scalable video coding, a flow-controlled user datagram protocol (UDP), and deadline-based criteria to manage the buffered data. Like transmission control protocol (TCP), ASViS adjusts the flow based on available bandwidth, and it can discard data based on video frame deadlines to prevent outdated data transmission. ASViS is compliant with RFC 8085, preventing it from overwhelming the Internet. The scalability feature allows ASViS to have the highest image quality possible in every frame allowed by SVC with the data layers available. A theoretical model is presented that predicts ASViS behavior under different network conditions. This work also shows how different parameters affect its performance and how it can be easily configured to optimize it.
