Programa de desarrollo de la creatividad a través de la expresión y comunicación de emociones

Con la presente investigación se pretende conocer los resultados de la aplicación del programa de comunicación y expresión emocional, DISEMFE-CREA. La investigación va a llevarse a cabo en niños con un nivel de quinto de primaria, entre ellos, un grupo de alumnos con Síndrome de Down. En nuestro proyecto han colaborado cuatro centros pertenecientes a la provincia de Sevilla, donde se realizan un test y un cuestionario antes del desarrollo del programa, y después del mismo. El objetivo de esta recogida de datos, es comparar si los resultados han sufrido cambios antes y después del programa. Tras el análisis de los resultados, se concluye que, en nuestra muestra, tres de los centros donde se ha llevado a cabo el programa, han aumentado su nivel de creatividad, obteniéndose puntuaciones más altas en casi todos los factores de la mismaWith this current investigation, we pretend to develop the skill of the creativity through a communication and emotional expression plan called: “DISEMFE-CREA”. The investigation is going to be conducted with children who have a level of the fifth course of Primary education. As a matter of fact, some of them have special educational needs, a group of student called specifically “Syndrome de down”. In our project, there are four educational centers from Seville which have cooperated with us in order to do a survey before and after of the development of the programme. The aim of this study is to compare if the resulting data have experienced important changes throughout the whole programme, before and after. As a result of the analysis, we may conclude that three educational centers have increased the creativity level. In this sense, we have obtained high scores in almost all the items.Universidad de Sevilla. Grado en Educación Primari

Discrete inverse problem on grids

In this work, we present an algorithm to the recovery of the conductance of a n –dimensional grid. The algorithm is based in the solution of some overdetermined partial boundary value problems defined on the grid; that is, boundary value problem where the boundary conditions are set only in a part of the boundary (partial), and moreover in a fix subset of the boundary we prescribe both the value of the function and of its normal derivative (overdetermined). Our goal is to recover the conductance of a n –dimensional grid network with boundary using only boundary measurements and global equilibrium conditions. This problem is known as inverse boundary value problem . In general, inverse problems are exponentially ill–posed, since they are highly sensitive to changes in the boundary data. However, in this work we deal with a situation where the recovery of the conductance is feasible: grid networks. The recovery of the conductances of a grid network is performed here using its Schr ¨odinger matrix and boundary value problems associated to it. Moreover, we use the Dirichlet–to–Robin matrix, also known as response matrix of the network, which contains the boundary information. It is a certain Schur complement of the Schr ¨odinger matrix. The Schur complement plays an important role in matrix analysis, statistics, numerical analysis, and many other areas of mathematics and its applications.Postprint (author's final draft

Dirichlet-to-Robin matrix on networks

In this work, we de ne the Dirichlet{to{Robin matrix associated with a Schr odinger type matrix on general networks, and we prove that it satis es the alternating property which is essential to characterize those matrices that can be the response matrices of a network. We end with some examples of the sign pattern behavior of the alternating paths.Postprint (author's final draft

Green functions on product networks

We aim here at determining the Green function for general Schrödinger operators on product networks. The first step consists in expressing Schrödinger operators on a product network as sum of appropriate Schrödinger operators on each factor network. Hence, we apply the philosophy of the separation of variables method in PDE, to express the Green function for the Schrödinger operator on a product network using Green functions on one of the factors and the eigenvalues and eigenfunctions of some Schrödinger operator on the other factor network. We emphasize that our method only needs the knowledge of eigenvalues and eigenfunctions of one of the factors, whereas other previous works need the spectral information of both factors. We apply our results to compute the Green function of Pm×Sh , where Pm is a Path with m vertices and Sh is a Star network with h+1 vertices.Peer ReviewedPostprint (author's final draft

Dental research in Spain. A bibliometric analysis on subjects, authors and institutions (1993-2012)

Background: Bibliometrics is defined as the use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Our objective was to characterize Spanish scientific output in Dentistry through the analysis of Web of Science database in a 20- year period. By means of a bibliometric study documents were statistically analyzed using indicators that showed quantitative and qualitative aspects of the production. Specifically, time course of the scientific production within the time span was analysed, as were the journals where the article was published and the categories of Journal Citation Reports (JCR) in which they belong, thematic areas, authorship, and finally authors and institutions with the highest production in Spain. Material and Methods: By means of the design of a specific search strategy previously described in the scientific literature, we recovered all citable documents about Dentistry signed by Spanish researchers and included in the WoS database between 1993 and 2012. Results: A total of 3006 documents fulfilled the search criteria, of which 2449 (81.5%) were published in journals within the category Dentistry Oral Surgery and Medicine and 557 (18.5%) within other categories of the JCR. During the four quinquenniums studied, the production increased quantitatively (8.6-fold) and qualitatively. Finally, the universities of Granada and Complutense of Madrid were the institutions with the highest production and most prolific authors. Conclusions: The Spanish dental production sharply increased in the last two decades, reaching quantitative and qualitative levels similar to those of the other medical specialties in the country

Deposition of gum rosin microspheres on polypropylene microfibres used in face masks to enhance their hydrophobic behaviour

[EN] The present study aims to investigate the effects of gum rosin (GR) microspheres coating over the hydrophobicity of the outer layer of a polypropylene (PP) based surgical face mask. The gum rosin coating was deposited over the surface of the face mask outer layer by electrospraying technique. The deposition of GR microspheres was confirmed by field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR) analysis. The thermal analysis determined a cooperative effect between the microspheres and the mask fibre to increase the maximum degradation rate temperature and the onset degradation temperature. To follow the effect of the GR microspheres coating over the hydrophobicity of the surgical face mask, FESEM and wettability analyses were conducted before and after 3, 6, and 9 h of wearing time. In the FESEM image, it was seen that the microsphere was homogeneously distributed over the nonwoven fibre and its presence increases the roughness of the fibres due to the bulge of microspheres. The wettability measurements suggest that the microspheres coating helps to keep the original hydrophobicity of the outer layer of the surgical face mask even after 6 h of wearing time. Indeed, after 9 h of wearing time, the water contact angle (WCA) of the GR coated face mask is higher than the WCA of the surgical face mask without the coating at 3 h of wearing time. Therefore, the gun rosin microspheres coating improved the hydrophobicity of the surgical face mask which may allow improved protection and/or extended lifetime of use.This research was funded by the Spanish Ministry of Economy and Competitiveness (MINECO), project: PROMADEPCOL (MAT2017-84909-C2-2-R).

Engagement And Solidarity While Learning

2020 and 2021 were difficult years for students attending higher education and secondary education especially if they were preparing to enter higher education. Teaching was adapted, and assessments were the possible ones according to what we lived and experienced. Thus, students need innovative and stimulating teaching and learning practices that motivate and involve them in the teaching/learning processes. Information and Communication Technologies (ICT) and digital platforms have seen their indiscriminate use, not without sometimes, teachers and students questioning whether they were being used in the best conceivable way or taken full advantage of. Face-to-face group work and involvement with the needs of colleagues lost some space for achievement and effectiveness. The preference for individual work and the visible reduction in solidarity among colleagues was an issue/question posed at the beginning of this study. An activity was proposed over a semester to students of Statistical Methods from Informatics Engineering. This curricular unit enrols 533 students, 85 on an after-work basis. The objective of this proposal was to create a collaborative learning platform where students could interact with each other within the scope of the curricular unit. Cumulatively, it was an objective that students deepen the topics taught in class, including references provided, and reviewing exercises conducted by their colleagues. Regularly professors corrected the materials proposed by the students. All students who participated had access to all the work developed. The evaluation of students\u27 involvement, collaboration, and solidarity in addition to the results will be discussed and presented

Effect of thickness on color and translucency of a multi-color polymer-infiltrated ceramic-network material

Objectives: To evaluate the effect of thickness on color and translucency of a multi-color polymer-infiltrated ceramic-network (PICN) material. Methods: Specimens of 0.5, 1.0, 1.5 mm thicknesses were obtained by sectioning VITA ENAMIC® multiColor (E-MC) High Translucent CAD-CAM blocks (1M1-HT, 1M2-HT, 2M2-HT, 3M2-HT, and 4M2-HT). Spectral reflectance and color coordinates were measured on white and black backgrounds using a spectroradiometer, CIE D65 illuminant and CIE 45 /0 geometry. CIEDE2000 color and translucency differences (ΔE00 and ΔTP00) between thicknesses and adjacent layers were evaluated using their respective 50:50% perceptibility and acceptability thresholds (PT00 and AT00). Results: In general, ΔE00 between thicknesses for all shades and layers were above AT00 in general. Chroma decreased from cervical to incisal layers with statistically significant differences (p < 0.05), and ΔE00 between sequential layers were above PT00, for all shades and thicknesses. TP00 decreased from 0.5 to 1.5 mm and increased from cervical to incisal layers for all shades with statically significant translucency differ- ences (p < 0.05). In general, for all thicknesses, TPT00 < ΔTP00 < TAT00 for sequential layers. Conclusions: The gradient in color and translucency of E-MC PICN material was influenced by the thickness of the CAD-CAM block. In addition, color and TP transi- tion values between the layers depends on the thickness and shade. Clinical significance: The effect of thickness must be taken into account by dental technicians and dentists when CAD-CAM multicolor PICN materials are used.University of Granada, Grant/Award Number: A.TEP.280.UGR18Spanish Ministry of Science, Innovation and Universities, Grant/ Award Number: PGC2018-101904-A-I00Government of Andalusia, Spain, Grant/Award Number: P20-0020

Optical and colorimetric evaluation of a multi-color polymer-infiltrated ceramic-network material

Objective To evaluate color, translucency parameter and optical properties (scattering (S), absorption (K) and transmittance (T)) of a multi-color polymer-infiltrated ceramic-network (PICN) material. Methods Samples of shades 1M1-HT, 1M2-HT, 2M2-HT, 3M2-HT, and 4M2-HT from VITA ENAMIC® multiColor (E-MC) High Translucent were fabricated (n = 3). CAD-CAM blocks were cut and polished to 1.00 ± 0.01 mm of thickness. Diffuse reflectance and color coordinates were measured against white and black backgrounds, using a calibrated spectroradiometer, CIE D65 illuminant and the CIE 45°/0° geometry. Color and translucency differences were evaluated using 50:50% perceptibility (PT and TPT) and 50:50% acceptability (AT and TAT) thresholds. S and K coefficients and T were calculated using Kubelka–Munk’s equations. Data was statistically analyzed using Kruskal–Wallis, Mann–Whitney tests, and VAF coefficient. Result Mean C* and b* values increased from incisal to cervical layers with statistically significant differences (p < 0.05). In general, ΔE00 between sequential layers were above PT for all shades. In addition, translucency parameter (TP) increased from cervical to incisal and ΔTP00 values were greater than TPT00 and lower than TAT00 between all sequential layers. Layers from all shades showed similar spectral behavior for S (97.4% ≤ VAF), K (85.0% ≤ VAF) coefficients and T (95.3% ≤ VAF). However, these values presented significant differences (p < 0.05) from cervical to incisal layers. Significance The gradient in color and translucency of this novel CAD-CAM multi-color PICN material can assist dental technicians and dentists to reach greater esthetics than the pre-existing CAD-CAM monolithicmaterials.Project JA TEP-1136 from “Junta de Andalucía”, SpainMAT2013-43946R from the Spanish Ministry of Economy and CompetitivenessCNPq Brazil grant #302587/2017-
