REALIDAD AUMENTADA COMO HERRAMIENTA EN EL PROCESO DE APRENDIZAJE EN LA MATERIA DE ENVASE Y EMBALAJE DEL DISEÑADOR INDUSTRIAL

ResumenLas instituciones educativas incorporan recursos pedagógicos basados en el uso de tecnología que contribuya al aprendizaje, esta investigación presenta el desarrollo e integración de un recurso educativo en la materia de envase y embalaje para los alumnos de la carrera de diseño industrial. La institución no cuenta con laboratorios de producción y experimentación para la realización de envases, dada esta circunstancia se elaboró un material didáctico basado en realidad aumentada; que establece la relación entre los conceptos teóricos y la realización física de los experimentos con los dispositivos reales. Se eligió el tema de polímeros porque la mayoría de los envases que se encuentran en el mercado son creados con este material, además cuenta con diversos procesos de configuración y producción. Fueron considerados y evaluados los aspectos pedagógicos y tecnológicos mediante el desarrollo de dos instrumentos que conforman la realidad aumentada, se aplicó al total de los alumnos de los dos grupos de segundo semestre, al igual que a sus respectivos docentes. Con los resultados se identificó la aceptación de la herramienta y con ello la posibilidad de desarrollar otros materiales para la licenciatura, a fin de que contribuyan con contenidos virtuales en el aprendizaje mediante el empleo de dispositivos electrónicos digitales como: computadoras personales, tabletas o teléfonos inteligentes.Palabras Clave: Estrategia de aprendizaje, recurso didáctico, tecnología. AbstractEducational institutions incorporate educational resources based on the use of technology that contribute to learning, this research presents the development and incorporation of an educational resource for the field of packaging for students of industrial design career. The institution does not have production and testing laboratories for producing containers, given this fact it was made a teaching material, based on an augmented reality. This material establishes between theoretical concepts and the physical realization of experiments with real devices. The subject polymer was chosen because most containers that are found in the market are created with this material besides that, it also has various settings and production processes. They were considered and evaluated pedagogical and technological aspects by the development of two instruments that make augmented reality, applied to all students in the two groups of second semester, as well as their teachers. With the results we could identify that the tool was accepted and thus the possibility of developing other materials for the career with the purpose that they contribute with virtual content in learning through the use of digital electronic devices such as personal computers, tablets or smartphones.Keywords:  Didactic resource, learning strategy, technology

Collaborative elicitation to select a sustainable biogas desulfurization technique for landfills

[EN] The 2015 Paris Agreement within the United Nations Framework Convention on Climate Change establishes three key ways for the reduction of the emissions of Greenhouse Effect Gases: mitigation, adaptation and resilience of ecosystems. In this context, one of the major goals for methane recovery from waste is the process of obtaining biogas from biomass or waste, a form of fuel with zero impact on the carbon footprint of the planet. All possible uses of biogas depend mainly on the degree of purification obtained. The removal of hydrogen sulfide (H2S) is the main weakness in using biogas in industrial applications. If the use of biogas is intended for engines, turbines or to enrich the biogas to obtain natural gas, lowering the levels of H2S will be necessary, in order to avoid corrosion in gas lines and in engines. Biogas desulfurization can be achieved through different techniques: physical, chemical, biological or hybrid procedures. Selecting the most sustainable technique to clean biogas entails a complex problem, which involves the analysis of these desulfurization treatments under different criteria. In this paper, we present a novel collaborative elicitation to select the consensus procedure for the reduction of the concentration of H2S in biogases from landfills. The elicitation technique is based on fuzzy set theory and VIKOR method in order to handle intangible data and to avoid potential bias by the panelists. The proposed hybrid method guarantees traceability and transparency to achieve consensus among the panel of experts during the decision making procedure.Curiel-Esparza, J.; Reyes-Medina, M.; Martín Utrillas, MG.; Martínez-García, MP.; Canto-Perello, J.

Utilidad diagnóstica de los anticuerpos antitransglutaminasa tisular en niños con síntomas digestivos crónicos y sospecha de celiaquía

Introduction: Celiac disease is the most common chronic enteropathy in the world, but its occurrence in children with chronic gastrointestinal symptoms in our environment is unknown. Objective: To evaluate the diagnostic utility of anti-tissue transglutaminase antibodies in children with chronic digestive symptoms. Methods: A prospective study was carried out from January 2008 to April 2011 at the José Luis Miranda Pediatric University Hospital in Santa Clara. It included 535 infants in which anti-tissue transglutaminase antibodies was screened. Duodenal transendoscopic biopsies were taken, which were interpreted according to the Marsh-Oberhuber classification and were related to the serological test. The diagnostic efficacy of the antibodies was assessed and the frequency of celiac disease was estimated. Results: Only 11 patients were positive for antibody determination (2.1%). The predominant type of anatomo-pathologic lesion in patients who were positive for antibodies was typical of celiac disease (9 boys, 75%). There was an agreement between the serological and histopathological diagnosis of the duodenum (K=0.78, p<0.001). The frequency of celiac disease in the series was 2.2% (12 patients). The sensitivity and specificity of the antibodies was 75% and 99% respectively. Conclusions: There was a low frequency of celiac disease in the series, and a good diagnostic accuracy of the serological tests in children suspected of suffering the disease was achieved.Introducción: la enfermedad celíaca es la enteropatía crónica más frecuente en el mundo, pero se desconoce su ocurrencia en niños con síntomas digestivos crónicos en nuestro medio.

Conclusiones: se demostró baja frecuencia de celiaquía en la serie y se obtuvo una buena eficacia diagnóstica de la prueba serológica en niños con sospecha de esta enfermedad

Evaluation of different Project Based Learning designs in an MSc degree

[EN] The design and implementation of different Project Based Learning (PBL) approaches are presented in this paper. All of them were carried out in the framework of the MSc degree in Electronic Systems for Smart Environments from the University of Malaga. Four subjects were developed using different values of the three main parameters of PBL: teamwork, self-guided learning and project complexity. During two academic years, several indicators were used to evaluate these experiences: compliance with subject time schedules, scores obtained for the students, interaction of each student in his team and satisfaction of students with the experiences. Our results encourage the use of PBL in bachelor degrees but, at the same time, confirm that PBL implementation is not a trivial task when projects are complex or when a high level of autonomous learning is required from students. Teamwork difficulties have also been found. So, we discuss the need of reaching a minimum level of proficiency in some key competencies before using PBL.This work has been partially support by an Educational Innovation Project (PIE10-80) of University of MálagaGarcía Berdonés, C.; Molina Tanco, L.; Peña Martín, JP.; García Lagos, F.; Joya Caparrós, G.; Reyes Lecuona, A.; Trujillo Aguilera, FD.

Rapid characterisation of the extremely large landslide threatening the Rules Reservoir (Southern Spain)

When an active landslide is first identified in an artificial reservoir, a comprehensive study has to be quickly conducted to analyse the possible hazard that it may represent to such a critical infrastructure. This paper presents the case of the El Arrecife Landslide, located in a slope of the Rules Reservoir (Southern Spain), as an example of geological and motion data integration for elaborating a preliminary hazard assessment. For this purpose, a field survey was carried out to define the kinematics of the landslide: translational in favour of a specific foliation set, and rotational at the foot of the landslide. A possible failure surface has been proposed, as well as an estimation of the volume of the landslide: 14.7 million m3. At the same time, remote sensing and geophysical techniques were applied to obtain historical displacement rates. A mean subsidence rate of the landslide around 2 cm/year was obtained by means of synthetic aperture radar interferometry (InSAR) and ground-penetrating radar (GPR) data, during the last 5 and 22 years, respectively. The structure-from-motion (SfM) technique provided a rate up to 26 cm/year during the last 14 years of a slag heap located within the foot of the landslide, due to compaction of the anthropical deposits. All of this collected information will be valuable to optimise the planning of future monitoring surveys (i.e. differential global positioning systems, inclinometers, ground drilling, and InSAR) that should be applied in order to prevent further damage on the reservoir and related infrastructures.This work was mainly supported by the European Regional Development Fund (ERDF) through the project “RISKCOAST” (SOE3/P4/E0868) of the Interreg SUDOE Programme.

Mutations in TRIM63 cause an autosomal-recessive form of hypertrophic cardiomyopathy

Objective: Up to 50% of patients with hypertrophic cardiomyopathy (HCM) show no disease-causing variants in genetic studies. TRIM63 has been suggested as a candidate gene for the development of cardiomyopathies, although evidence for a causative role in HCM is limited. We sought to investigate the relationship between rare variants in TRIM63 and the development of HCM. Methods: TRIM63 was sequenced by next generation sequencing in 4867 index cases with a clinical diagnosis of HCM and in 3628 probands with other cardiomyopathies. Additionally, 3136 index cases with familial cardiovascular diseases other than cardiomyopathy (mainly channelopathies and aortic diseases) were used as controls. Results: Sixteen index cases with rare homozygous or compound heterozygous variants in TRIM63 (15 HCM and one restrictive cardiomyopathy) were included. No homozygous or compound heterozygous were identified in the control population. Familial evaluation showed that only homozygous and compound heterozygous had signs of disease, whereas all heterozygous family members were healthy. The mean age at diagnosis was 35 years (range 15-69). Fifty per cent of patients had concentric left ventricular hypertrophy (LVH) and 45% were asymptomatic at the moment of the first examination. Significant degrees of late gadolinium enhancement were detected in 80% of affected individuals, and 20% of patients had left ventricular (LV) systolic dysfunction. Fifty per cent had non-sustained ventricular tachycardia. Twenty per cent of patients suffered an adverse cerebrovascular event (20%). Conclusion: TRIM63 appears to be an uncommon cause of HCM inherited in an autosomal-recessive manner and associated with concentric LVH and a high rate of LV dysfunction
