Student Research Work and Modeled Situations in Order to Bridge the Gap between Basic Science Concepts and Those from Preventive and Clinical Practice. Meaningful Learning and Informed beneficience  [PDF]
Elio A. Prieto González
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.77099
Abstract: Meaningful learning of basic science concepts is a difficult goal to reach among students from different health related university careers. We present an integrative approach based on different educational strategies like problem based, and situated learning as well as the use of models and organizers. Three cases from Medicine, Nursing and Nutrition show the difficulties in the comprehension and integration of basic and applied knowledge as well as the educational approaches adopted and the evolution of students. There is a discussion on the ethical relevance of deep basic and applied knowledge in the right solution of problems posed in class that attempt to model real life scenarios. There is a term introduced in this paper: informed beneficence. This concept expresses the assumption that the professional fulfillment of the ethical principle of beneficence is linked to knowledge and skills to propose appropriate solutions to individual or collective health problems.
Challenges Analyzing RNA-Seq Gene Expression Data  [PDF]
Liliana López-Kleine, Cristian González-Prieto
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.64053
Abstract: The analysis of messenger Ribonucleic acid obtained through sequencing techniques (RNA-se- quencing) data is very challenging. Once technical difficulties have been sorted, an important choice has to be made during pre-processing: Two different paths can be chosen: Transform RNA- sequencing count data to a continuous variable or continue to work with count data. For each data type, analysis tools have been developed and seem appropriate at first sight, but a deeper analysis of data distribution and structure, are a discussion worth. In this review, open questions regarding RNA-sequencing data nature are discussed and highlighted, indicating important future research topics in statistics that should be addressed for a better analysis of already available and new appearing gene expression data. Moreover, a comparative analysis of RNAseq count and transformed data is presented. This comparison indicates that transforming RNA-seq count data seems appropriate, at least for differential expression detection.
La consolidación del Monterrey "imaginario" en el contexto de la globalización: "Macroproyectos" urbanos
Prieto González, José Manuel;
Frontera norte , 2011,
Abstract: without ignoring functional effectiveness, cities are emphasizing seductive aesthetics as a tool for beneftting their own economy. over the last two decades, monterrey has joined a global trend that develops urban policies based on the construction of architectural and urban icons, and organizing large international cultural and sporting events, which are in themselves essential projects for transforming the city and solving its current problems. the development of urban "macroprojects" in monterrey has permitted the creation of an "imaginary city" -one that is marketable and ignores and substitutes the "real city". however, acting in this way entails its own risks, which is the subject of this article.
DETERIORO GENóMICO Y MANIPULACIóN GENéTICA: DESEQUILIBRIO EN LA PRIORIDAD DE LAS AGENDAS PúBLICAS
Prieto González,Elio A;
Acta bioethica , 2007, DOI: 10.4067/S1726-569X2007000200010
Abstract: unbalance in the treatment of two topics related to the conservation of the human genome integrity is analyzed here: the technologies for genetic manipulation and genome damage due to environmental pollution. lack of education and of information based on real facts, and the media sensationalist treatment, among other factors, provoke an unbalance between the media agenda and public needs. this leads to a lack of citizenship consciousness over the true threats that genetic material faces and the health risks that it involves
Extracción de puntos característicos del rostro para medidas antropométricas
González,Alejandro; Prieto,Flavio;
Revista Ingenierías Universidad de Medellín , 2010,
Abstract: in this research, a technique for the extraction of a 22 face landmarks set oriented to anthropometry applications has been proposed. the technique is based on wavelets gabor transformation and the elastic bunch graph matching (ebgm) algorithm. the ebgm algorithm was modified so that the extracted points correspond to face landmarks which are commonly used in face anthropometric measures. modifications were: some geometric restrictions to initially fit the centers location of the region search, and later for the definition of the region. results show that the face central points present location errors smaller than a millimeter, which is consistent with the measures in direct face anthropometry.

Abstract: Se analiza el desequilibrio en el tratamiento de dos temas que ata en a la conservación de la integridad del genoma humano: las tecnologías de manipulación genética y el deterioro genómico provocado por la contaminación ambiental. Las carencias educativas, la falta de información asentada en los hechos y un manejo sensacionalista en los medios, entre otros factores, desajustan las agendas mediáticas con las necesidades públicas, lo que desemboca en una falta de conciencia ciudadana acerca de las verdaderas amenazas a las que está expuesto el material genético y los riesgos de salud que ello implica O presente texto analisa o desequilíbrio no tratamento de dois temas que dizem respeito à conserva o da integridade do genoma humano: as tecnologias de manipula o genética e a deterioriza o gen mica provocada pela contamina o ambiental.

La consolidación del Monterrey "imaginario" en el contexto de la globalización: "Macroproyectos" urbanos
José Manuel Prieto González
Frontera norte , 2011,
Abstract: Sin renegar de la eficiencia funcional, las ciudades están poniendo mucho empe o en la seducción estética como herramienta de beneficio económico. Monterrey se ha sumado a una corriente global que concibe el desarrollo de políticas urbanas a partir de la construcción de íconos arquitectónicos y urbanísticos, y de la organización y celebración de grandes eventos culturales y deportivos de alcance internacional, como instrumentos esenciales para transformar la ciudad y solucionar sus problemas. La realización de "macroproyectos" urbanos en Monterrey ha permitido configurar una "ciudad imaginaria" -"vendible"- que ignora y suplanta a la "ciudad real". Actuar así, sin embargo, conlleva riesgos. éste es el tema del presente artículo.

Extracción de puntos característicos del rostro para medidas antropométricas Face landmarks extraction for anthropometric measures
Alejandro González,Flavio Prieto
Revista Ingenierías Universidad de Medellín , 2010,
Abstract: En este documento se propone una técnica para la extracción de 22 puntos característicos del rostro, orientada a aplicaciones de antropometría. La técnica se fundamenta en la transformada wavelets-Gabor y el uso del algoritmo EBGM (del término en inglés: Elastic Bunch Graph Matching). Este último algoritmo fue modificado para que los puntos extraídos correspondan a puntos característicos del rostro, los cuales se utilizan comúnmente en medidas antropométricas faciales. Las modificaciones consisten en un conjunto de restricciones geométricas para ajustar inicialmente la ubicación de los centros de búsqueda, y posteriormente para la definición de la región de esta búsqueda. Los resultados mostraron que los puntos centrales del rostro presentan errores de ubicación inferiores al milímetro, lo cual es consistente con las medidas en antropometría facial directa. In this research, a technique for the extraction of a 22 face landmarks set oriented to anthropometry applications has been proposed. The technique is based on wavelets Gabor transformation and the Elastic Bunch Graph Matching (EBGM) algorithm. The EBGM algorithm was modified so that the extracted points correspond to face landmarks which are commonly used in face anthropometric measures. Modifications were: some geometric restrictions to initially fit the centers location of the region search, and later for the definition of the region. Results show that the face central points present location errors smaller than a millimeter, which is consistent with the measures in direct face anthropometry.
A propósito de la nueva orientación dada a las pensiones de arquitectura en el extranjero a mediados del siglo XIX. Francisco de Cubas y su proyecto para una Casa de Maternidad
Prieto González, José Manuel
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 1998,
Abstract: One of the reforms that the architectural profession underwent in the mid-nineteenth century was the substitution of the traditional and exclusivelly artistic focus of students sojourns abroad for a tendency that combined the two dominant aspects of architecture: art and science. This transformation was encouraged by the aspiration of the new liberal bourgeois regime. The project of Francisco de Cubas abroad illustrates this development fo the first time. Entre las reformas experimentadas en el ámbito de la arquitectura a mediados del siglo pasado se encuentra la subrogación del tradicional y exclusivo enfoque artístico de sus pensiones en el extranjero, por otro que, más en consonancia con los requerimientos del nuevo régimen liberal-burgués, concilia los dos componentes básicos de la carrera y la profesión, el arte y la ciencia. Un proyecto del pensionado Francisco de Cubas ejemplifica por vez primera este cambio.
