Atención sincronizada de tele rehabilitación en zonas rurales con apoyo de ayudas tecnológicas tele operadas: aplicación a un caso colombiano
Get PDFObjective: this research work proposes and evaluates a model for the provision of physical rehabilitation services supported by teleoperated technological aids, using the Internet as a communication channel for the care of the rural population, and by taking as the study region, a western subregion of Colombia around the municipality of Santiago de Cali-Colombia. Methodology: from the dynamics generated by the interaction between the service system and the users, characterized by the occurrence of events, a formal model was built, using a Colored Petri Net. To do this, a modelling methodology based on a top-down approach was proposed. Results: a model of the care system was developed and evaluated using Petri nets, based on a case study consisting of the current care model offered by a typical health service provider in Cali called "La Ladera ESE Health Network". The weighted improvements through the proposed system were: greater objectivity of traceability, speed of communication, better quality of rehabilitation, as well as the ability of the new system to contribute to greater precision in the initial diagnosis and subsequent periodic evaluation of recovery. Conclusions: the proposed protocol based on the model made it possible to attend concurrently and accurately diagnose up to three patients, through the implementation of technological aids to improve diagnostic support and allow a subsequent periodic evaluation of the patient´s recovery.Objetivo: este trabajo de investigación propone y evalúa un modelo para la prestación de servicios de rehabilitación física apoyados en ayudas tecnológicas tele operadas, utilizando Internet como canal de comunicación para el cuidado de la población rural, y tomando como región de estudio, una subregión del occidente de Colombia alrededor el municipio de Santiago de Cali-Colombia. Metodología: a partir de la dinámica generada por la interacción entre el sistema de servicios y los usuarios, caracterizada por la ocurrencia de eventos, se construyó un modelo formal, utilizando una Red Petri Coloreada. Para ello, se propuso una metodología de modelado basada en un enfoque top-down. Resultados: se desarrolló y evaluó un modelo del sistema de atención utilizando redes de Petri, a partir de un caso de estudio consistente en el modelo de atención actual que ofrece un proveedor de servicios de salud típico de Cali denominado "Red de salud La Ladera ESE". Las mejoras ponderadas a través del sistema propuesto fueron: mayor objetividad de trazabilidad, rapidez de comunicación, mejor calidad de rehabilitación, así como la capacidad del nuevo sistema para contribuir a una mayor precisión en el diagnóstico inicial y posterior evaluación periódica de recuperación. Conclusiones: el protocolo propuesto, basado en el modelo, permitió atender de manera concurrente y precisa el diagnóstico de hasta tres pacientes, mediante la implementación de ayudas tecnológicas para mejorar el soporte diagnóstico y permitir una posterior evaluación periódica de la recuperación del paciente
Modelado de un proceso de tratamiento de agua potable y las variables involucradas utilizando Redes de Petri Coloreadas
No full textA model that represents the behavior of a critical system or process, such as the drinking water treatment process, is vital for the evaluation of new procedures or their optimization without affecting the real system or risking the population, avoiding economic losses. Due to the complexity in the dynamics of drinking water treatment plants, the use of Coloured Petri Nets is recommended to model the behavior of the variables involved in the process. In this context, this work presents a structured procedure that allows obtaining a model considering a dynamic driven by the occurrence of discrete events and that generates useful information to verify the effectiveness and efficiency of new operating strategies. To evaluate this proposal, a model of the drinking water treatment process of Puerto Mallarino located in Cali, Colombia was developed, modeling both the stages of the purification process and the approximate behavior of the variables involved under the assumption that changes only respond to the intensity of the rainy season.
El disponer de un modelo que represente el comportamiento de un sistema o proceso crítico, como lo es el proceso de una planta de purificación de agua, resulta de vital importancia a la hora de evaluar nuevos procedimientos u optimizarlos sin afectar el sistema real o poner en riesgo a la población, evitando así pérdidas económicas. Debido a la complejidad en la dinámica de las plantas de purificación de agua, se recomienda el uso de redes de Petri coloreadas para modelar el comportamiento de las variables involucradas en el proceso. Este trabajo presenta un procedimiento estructurado para obtener un modelo considerando una dinámica dirigida por la ocurrencia de eventos discretos y que permite la generación de información útil para verificar la efectividad y eficiencia de nuevas estrategias de operación en una planta de tratamiento de agua potable. Para evaluar esta propuesta, se desarrolló un modelo de la planta de tratamiento de agua potable de Puerto Mallarino en Cali, Colombia, modelando tanto las etapas del proceso de purificación como el comportamiento aproximado de las variables bajo la suposición de que los cambios obedecen a la intensidad de las estaciones de lluvia.
 
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
