La fábula digital, un recurso didáctico para la enseñanza de la literatura

Es innegable que las TIC en la aldea global han tenido gran impacto en diferentes campos sociales como la educación gracias a sus significativas ventajas a la hora de captar la atención de los educandos. Por ello resulta importante apostarle a un proyecto en el contexto escolar que afecte positiva y significativamente los procesos de enseñanza y aprendizaje de la fábula en una institución educativa del municipio de Dosquebradas. La implementación de un blog interactivo a través del diseño de una secuencia didáctica conducirá a los estudiantes paso a paso en el aprendizaje significativo del género fabula aprovechando los recursos digitales

Art-Based Healing Strategies in Colombia in the Context of Collective Trauma: A Literature Review

In Colombia, a country severely impacted by centuries of violence, many communities resorted to the use of art to overcome their collective trauma. The present research answers the question: “What is the existing literature that supports arts-based healing knowledge that has been developed in Colombia?” This research collects relevant data on the topic, gathered from professionals of different academic fields and reflects on it through an art therapy lens. Art-based healing strategies are reported in the literature associated with social and economic empowerment, reconnection of social fabric, transformation of social patterns and construction of hope. The present research highlights the ways in which art makes this possible. The findings of this paper build theoretical foundations that can be used in the integration of art-based healing strategies into existing therapeutic structures

Tunable ring resonator filter for OFDM Transmission systems

A novel tunable filter is theoretically demonstrated. It is based on a ring resonator with an amplifier and a noise filter in the loop. This optoelectronic device has potential as a high-sensitivity receiver and as a tunable demultiplexer in OFDM transmission systems.Publicad

Discrimination of milks with a multisensor system based on layer-by-layer films

Producción CientíficaA nanostructured electrochemical bi-sensor system for the analysis of milks has been developed using the layer-by-layer technique. The non-enzymatic sensor [CHI+IL/CuPcS]2, is a layered material containing a negative film of the anionic sulfonated copper phthalocyanine (CuPcS) acting as electrocatalytic material, and a cationic layer containing a mixture of an ionic liquid (IL) (1-butyl-3-methylimidazolium tetrafluoroborate) that enhances the conductivity, and chitosan (CHI), that facilitates the enzyme immobilization. The biosensor ([CHI+IL/CuPcS]2-GAO) results from the immobilization of galactose oxidase on the top of the LbL layers. FTIR, UV–vis, and AFM have confirmed the proposed structure and cyclic voltammetry has demonstrated the amplification caused by the combination of materials in the film. Sensors have been combined to form an electronic tongue for milk analysis. Principal component analysis has revealed the ability of the sensor system to discriminate between milk samples with different lactose content. Using a PLS-1 calibration models, correlations have been found between the voltammetric signals and chemical parameters measured by classical methods. PLS-1 models provide excellent correlations with lactose content. Additional information about other components, such as fats, proteins, and acidity, can also be obtained. The method developed is simple, and the short response time permits its use in assaying milk samples online.Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (project AGL2015-67482-R)Junta de Castilla y Leon - Fondo Europeo de Desarrollo Regional (project VA-011U16)Junta de Castilla y León (grant BOCYL-D-4112015-9
