A homogeneously filled triangular region with waveguide arms is considered as a possible building block when analyzing complicated H-plane structures by means of generalized scattering matrices. For triangular boundaries, a specific field representation i... see more

The microstructure, crystallographic structure and magnetic properties of ferroelectric-ferromagnetic PZT/CoCr heterostructures have been investigated by using XRD, SEM and VSM.~Upon applying an electric field, the in-plane magnetization of the heterostru... see more

Shading and inter-reflections created by the three-dimensional coral canopy structure play an important role on benthic reflectance and its propagation above the water. Here, a plane parallel model was coupled with a three-dimensional radiative transfer c... see more

The compound-structure permanent-magnet synchronous machine (CS-PMSM), comprising a double rotor machine (DRM) and a permanent-magnet (PM) motor, is a promising electronic-continuously variable transmission (e-CVT) concept for hybrid electric vehicles (HE... see more

This research was conducted to analyze the Mg doping concentration effect on the structure, morphology, and optical properties of ZnO thin film prepared using the sol gel spin coating method. The Mg concentration was varied in the mole fraction of 1%, 3%,... see more

The article describes the problem of spontaneous transformation of the planetary matrix of the social world, moving from the cell to the network structure, resulting not only in the changes of the world system of the planetary community, the shapes of nat... see more

Desarrollo de habilidades investigativas en el proceso formativo de los estudiantes de Medicina / Development of research skills in the training process of medical studentsDesarrollo de habilidades investigativas en el proceso formativo de los estudiantes de Medicina / Development of research skills in the training process of medical studentsde las Ciencias de la Salud, en especial de los médicos que egresan con la responsabilidad de asumir el trabajo en la Atención Primaria de Salud. Dada las insuficiencias de los estudiantes de medicina en el componente investigativo del proceso formativo, lo que incide en los modos de actuación de los graduados, se realizó una  investigación descriptiva y transversal. El objetivo consiste en  determinar cómo se comporta el  desarrollo de habilidades investigativas en el proceso formativo de los estudiantes de medicina durante el período enero  -  junio del año 2009.  El universo estuvo constituido por todos los estudiantes de medicina de la Universidad de Ciencias Médicas de Pinar del Río. Se seleccionó una muestra de forma aleatoria, estratificada y representativa, que incluyó a los estudiantes de todos los años de la carrera, profesores y directivos de la carrera. Se realizó una revisión bibliográfica, y  el análisis documental de los planes de estudio, utilizando como métodos empíricos: la encuesta, la entrevista y la opinión de expertos. El diagnóstico incluyó la aplicación de una encuesta a los estudiantes de la carrera de medicina, y entrevistas semiestructuradas a los profesores de la carrera. Se concluye que la mayoría de los estudiantes consideran los temas sobre metodología de la investigación recibida como insuficiente para el desarrollo de habilidades investigativas, los temas que investigan responden a intereses personales y los orientados por el tutor. La actividad científica estudiantil  constituye la principal vía identificada para el desarrollo de habilidades investigativas. Los estudiantes consideran muy necesario la disciplina  metodología de la investigación en su plan de estudio.Palabras clave: MEDICINA,  METODOLOGÍA, ESTUDIANTE.ABSTRACTThe necessity of increasing the quality of preparation for the research process of graduates in Medical Sciences is a matter of discussion in last academic courses, particularly medical personnel having the responsibility for taking on the work of Primary Health Care. In view of the insufficiencies of medical students on the research component during the training process, which bears on the ways the graduates perform, a descriptive and cross-sectional study was conducted. The objective was to determine the behavior of research skills in the training process of medical students during January-June 2009. The universe was comprised of all the students enroll at Medical College in Pinar del Rio. The sample was chosen at random, stratified and representative, that included the medical students enroll in all the academic years of medical studies, teaching staff and directors. A literature review and a documentary analysis of the syllabuses were carried out using empirical methods: survey, interview and the opinion of the experts. The instruments applied included a survey to the medical students and semi-structured interviews to professors. Concluding that the majority of the students consider the topics about methodology of research insufficient to develop skills, these topics respond to personal interest advised by the tutor. Student scientific activity represents the main identified way to develop research skills. Students consider the discipline of Methodology of Research very necessary in the syllabus.Key words: MEDICINE, METHODOLOGY, STUDENTS.

Extending results of Hershberger and Suri for the Euclidean plane, we show that ball hulls and ball intersections of sets of n points in normed planes can be constructed in O(nlog?n) time. In addition, we confirm that the 2-center problem w... see more

The subject matter of research in the article is the morphological structure of bone tissue in the lumbar spine, visualized by tomography in the sagittal and axial planes. The goal of the research is to create the most informative investigation method for... see more
