ABSTRACT
In recent years, communication systems, including RFID, have been used in intelligent beehives for beekeeping. RFID systems in the UHF frequency band offer reading distances of tens of centimetres, allowing the localisation and identification of the queen bee inside the hive. With this purpose, this work proposes an analysis of an environment of propagation that consists of a honeycomb frame, where the reader is placed within the frame, and the tag is placed in different positions over it. A honeycomb frame consists of a wooden box containing a honey wax panel, supported by metallic wires. The environment is modelled theoretically using its S-parameters and simulated in CST Studio. An analysis of these results and empirical measurements is performed. The results show that a periodicity in the received power of the tag is found with respect to the distance to the reader when the tag is located in a direction parallel to the wire, where local maximum and minimum values are found. Additionally, when the tag is placed over a wire of the frame, a higher received power is obtained compared to the case where the tag is placed between two wires. Furthermore, it has been observed that the reading range has increased with respect to free space, covering the full frame.
ABSTRACT
Fundamento: es importante la identificación de un grupo de competencias propias de la labor docente de los médicos de familia, que actúan como tutores en los escenarios formativos en la Atención Primaria de Salud. Objetivo: identificar las competencias docentes principales de los médicos de la familia, que se desempeñan como tutores en la carrera de Medicina, en el policlínico Área II del municipio de Cienfuegos. Método: investigación pedagógica de tipo descriptiva, en el que buscaba definir el grupo de competencias docentes básicas (académicas, didácticas y organizativas, para favorecer una gestión pedagógica de mayor calidad en los consultorios médicos como escenario formativo del Policlínico Universitario Cecilio Ruíz de Zárate durante el año 2010. Resultados: el 61,5 por ciento de los tutores tienen más de 10 años de formación médica, más de la mitad, el 73,1 por ciento de ellos no están categorizados, el 84,6 por ciento son especialistas de Medicina General Integral, más de la mitad recibieron el taller de preparación para tutores y el 96,2 por ciento consideran las competencias básicas como muy importantes. Conclusiones: predominó el sexo femenino, la mayoría de los profesionales tenían más de 10 años de experiencia como médico, existen deficiencias en el modo de actuación del tutor por la falta de personal categorizado, la mayor parte de los encuestados son especialistas en Medicina General Integral, la escasa preparación pedagógica de los profesionales, la utilización de la autopreparación como forma de mejorar los conocimientos pedagógicos y dentro de las competencias docentes básicas predominó la importancia del dominio de los conocimientos a impartir(AU)
Background: for the identification of a group of competitions characteristic of the educational work of the Family doctors that you/they act as tutors in the formative scenarios of the Primary Attention of Health in University Policlínico Cecilio Ruíz of Zárate. Objective: to identify the educational main competitions of the doctors of the family like tutors in the career of Medicine, in the Area II of the municipality of Cienfuegos. Method: pedagogic investigation of descriptive type in the mark of the medical education that looked for to define the group of educational basic competitions, what can favor a pedagogic management of more quality in the medical clinics as formative scenario of University Policlínico Cecilio Ruíz of Zárate during the year 2010. Results: 61,5 percent of our tutors has more than 10 years of medical formation; more than the half, their 73.1 percent is not categorized, 84.6 percent is specialist of general integral medicine, but of the half they received the preparation shop for tutors and 96.2 percent they consider the basic competitions as very important. Conclusion: deficiencies exist in the way of the tutor's performance for categorized personnel's lack, pedagogic scarce preparation and the assistance load of the professors in the primary attention of health(AU)
