[en] The number of sport centres, members of such centres and companies that manage them have grown significantly over the last 10 years. However, these centres register a high rate of dropouts, which becomes one of their main problems. Moreover, several studies suggest that a certain percentage of these dropouts involves a complete abandonment of physical activity, with all the consequences that it implies from a community point of view. Literature clearly identifies loyalty as an effective tool to prevent dropouts. In addition, a great number of studies analyse the relation between loyalty and other concepts such as perceived quality, satisfaction or recommendations as key aspects to guarantee members continuity. Nevertheless, the majority of these studies use questionnaires to measure it. In this study, we intend to analyse if behavioural variables, commonly recorded in the management software of sports centres, can predict the probability of dropping out in these centres. In the same way, we will evaluate the effectiveness of the model in different samples of the same sport centre and will assess whether every centre needs its own predictive model.

[gl] O número de centros deportivos, os abonados a estes centros e as empresas que os xestionan incrementáronse nos últimos 10 anos de maneira notable. Estes centros con todo, rexistran unha alta incidencia de baixas, o que se converte nun dos seus principais problemas. Diversos estudos expoñen que unha porcentaxe destes abandonos ademais implican o cesamento da práctica deportiva, coas consecuencias que iso supón desde o punto de vista comunitario. A literatura identifica claramente a fidelidade como unha ferramenta eficaz para previr as baixas. Ademais, numerosos estudos analizan a relación desta fidelidade con conceptos como a calidade percibida, a satisfacción ou a recomendación dos clientes como aspectos crave que garantirán a continuidade dos abonados. Con todo, a maioría destes estudos utilizan complexas enquisas para a súa medición. No presente traballo, pretendemos estudar se as variables de comportamento, rexistradas habitualmente nos softwares de xestión destes centros, poden ser predictivas da baixa do centro deportivo. Así mesmo, comprobaremos a eficacia do modelo nunha mostra diferente do mesmo centro deportivo e analizaremos se cada centro deportivo responde ao seu propio modelo predictivo.
[en] The intestinal microbiota is influenced by multiple factors and is decisive in health and in the development of diseases such as asthma or obesity. It can be modulated through diet and prebiotics, substrates that reach the colon and are metabolized by colonic bacteria, which produce beneficial molecules for the individual. The properties of prebiotics depend on their physicochemical characteristics, with low DP oligogalacturonides being an interesting alternative. This project proposes a method for the production of low molecular weight oligogalacturonide mixtures starting from lemon peel residues, which were processed by means of multi-stage aqueous extraction, hydrothermal treatment at 1550C and hydrolysis with commercial preparations of pectinases. The obtained mixtures presented antioxidant capacity.

[gl] A microbiota intestinal está influenciada por múltiples factores e é determinante na saúde e no desenvolvemento de enfermidades como a asma ou a obesidade. Pódese modular mediante a dieta e os prebióticos, sustratos que chegan ao colon e que son metabolizados polas bacterias colónicas, que producen moléculas beneficiosas para o individuo. As propiedades dos prebióticos dependen das súas características fisicoquímicas, sendo unha alternativa interesante os oligogalacturónidos de baixo DP. Este proxecto propón un método para a produción de mesturas de oligogalacturónidos de baixo peso molecular a partir de residuos de casca de limón, que foron procesados mediante extracción acuosa multietapa, tratamento hidrotermal a 1550C e hidrólise con preparados comerciais de pectinasas. As mesturas obtidas presentaron capacidade antioxidante.
[en] Soil water erosion acts on the carbon cycle, because it affects soil organic matter content and produces sediments, which are transferred it to the waters. This paper analyzes the effects of water erosion carried out by simulated rain on the total contents and structure of soil organic matter. We selected two different soil, developed over schist and granite, respectively. Each soil was submitted to 284 mm of simulated rain on microplots of 1m2. Initial (undisturbed) and final (degraded by erosion) surface layers of the studied soils and the respective sediments were sampled. Measurements of total carbon and nitrogen, and infrared spectroscopy (IR) were made in soil and sediment samples. The IR spectra were determined before and after removal of soil organic matter. Soil developed on granite was richer in carbon and nitrogen that the soil developed on schist and the contents of these elements varied during erosion. The inorganic fraction of undisturbed samples, eroded samples and sediments on schist showed a similar spectral response. The spectral response indicates that this fraction is dominated by kaolinite in two the soils studied. IR spectra also highlight differences in the structure of organic compounds in the undisturbed soil, the soil degraded by erosion and the sediments. Modifications affecting the structure of the soil organic matter content showed differences between samples of materials developed either on schist or on granite; therefore, the soil composition, mainly texture and organic matter content also affect the spectral response.

[gl] A erosión hídrica intervén no ciclo do carbono, xa que afecta ó contido en materia orgánica do solo e produce sedimentos que a transfiren ás augas. Neste traballo analízanse os efectos da erosión inducida por choiva simulada sobre o contido total e a estrutura da materia orgánica. Seleccionáronse dous solos, un desenvolvido sobre esquisto e o outro sobre granito. Cada solo someteuse á acción de 284 mm de choiva simulada en microparcelas de 1 m2. Mostreáronse as superficies iniciais (non alterada) e finais (degradada) dos solos estudados e os sedimentos producidos. Nas mostras de solo e sedimento leváronse a cabo determinacións de carbono e nitróxeno total, e de espectroscopía de infravermellos (IR). Os espectros de IR determináronse antes e despois de eliminar a materia orgánica. O solo desenvolvido sobre granito é máis rico en carbono e nitróxeno que o de esquisto e o contido destes elementos varía durante a erosión. Sobre esquisto, a fracción inorgánica do solo sen alterar, do solo erosionado e dos sedimentos presentan unha resposta espectral similar. A resposta espectral desta fracción indica que en dous solos predomina a caolinita. Os espectros de IR tamén poñen de manifesto diferenzas na estrutura dos compostos orgánicos do solo non alterado, o solo degradado e os sedimentos. Apreciáronse diferenzas entre as modificacións que sofre a estrutura da materia orgánica entre solos sobre esquisto e sobre granito; por tanto, a composición do solo, en particular a textura e o contido en materia orgánica afectan á reposta espectral.
[en] The propaganda develops as a fundamental factor in the adhesión inside the modern States-nation for is own stability or the legitimation as the develop of new politcal models inside it. Therefore, in this job, is proposed the study of the propaganda launched during the Second World War from de United Kingdom and the nazi Germany to know the diferences between both propaganda models thereby the influence of a external factor as the war to modificate them. To do it, we will stablish the objectives of the propaganda during a war conflicto to do a subsequent study between both models to his comparation. We will see, then, how many diferences between the regimes in relation to the freedom of speech or the diffusion of the propaganda before the war will blur at the moment the bombs star to explode and all the channels unify, if they weren´t already, in favor of the objectives of the State: win the war.

[gl] A propaganda desenvólvese como factor fundamental de adhesión dentro dos Estados-nación modernos tanto para a sua propia estabilidade ou a lexitimación dos seus obxetivos como para o desenrolo de novos políticos dentro de él. Así, neste traballo, proponse o estudo da propaganda lanzada durante a Segunda Guerra Mundial polo Reino Unido e pola Alemaña nazi para coñecer as diferencias entre ambos modelos políticos así como a influencia dun factor externo como o é a guerra para modificalos. Para iso, establecernos cales son os obxetivos da propaganda nun conflito bélico para o posterior estudo entre ambos modelos para a sua comparación. Veremos, polo tanto, como varias diferencias existentes entre os reximenes en relación a liberdade de expresión ou a difusión de propaganda antes da guerra difuminanse no momente en que as bombas comezan a estoupar e todos os canles se unifican, se non o estaban xa, nos obxetivos do Estado: gañar a guerra.
[en] Introduction: handball is a sport of high contact and multiple changes in rhythm, intensity and jumps so injuries presented in the lower limbs are a concern in this area due to the large number of them throughout the sports career of the player. The lateral sprains in inversion in the ankle are the most frequent injuries in this sport, but the variables that can increase the risk of this injury and others in lower limbs have not been sufficiently studied. The aim of this study is to determine the prevalence of foot injuries related to handball practice and in turn to determine variables associated with these injuries. Methodology: A cross-sectional, observational, descriptive study will be carried out where the different pathologies in the foot suffered by the athletes will be evaluated through the anamnesis and exploration of they and if there is any variable that we have analysed that increases the probability of suffering an injury.

[gl] Introdución: o balonmano é un deporte de alto contacto e múltiples cambios no ritmo, a intensidade e os saltos, polo que as lesións presentadas nos membros inferiores son unha preocupación nesta área debido ao gran número deles ao longo da carreira deportiva dos xogador As torceduras laterales en inversión no nocello son as lesións máis frecuentes neste deporte, pero as variables que poden aumentar o risco desta lesión e outras nas extremidades inferiores non foron suficientemente estudadas. O obxectivo deste estudo é determinar a prevalencia de lesións nos pés relacionadas coa práctica do balonmán e á súa vez para determinar as variables asociadas a estas lesións. Metodoloxía: Realizarase un estudo transversal, observacional e descritivo, onde se evaluarán as distintas patoloxías do pé sufridas polos atletas mediante a anamnese e exploración dos mesmos e se hai algunha variable que analizamos que aumenta a probabilidade de sufrir unha lesión.
[en] This research makes a biographical study about María Luisa Navarro Margati, teacher and pedagogue, whose training and profession are part of the Spanish renewal movement of the first third of the twentieth century. Her teaching work is confined to the Colegio Nacional de Sordomudos in Madrid (1912-1936). In the 20s and 30s of the last century she collaborated in the Madrid press, besides being co-founder and collaborator of Boletín Escolar (1917) and the Revista de Pedagogía (1922-1936). Around the same time, she stands out as a translator and commentator of authors who are limited to the New School. She is one of the few women who managed to become visible in the Second Spanish Republic; visibility that will cost her exile. She will live in England for a few years, far from working life. However, the Argentine exile will allow her to recover it: lectures, courses, university chair in Tucumán, and again the publishing world through Losada. Shortly before her death she left teaching duties to dedicate herself again to social work (as she did in the republican years and very briefly in England): she founded and directed the Commission of Aid to the Spanish Democrat (1945), to assist Spanish refugees in southern France.

[gl] Esta investigación realiza un estudo biográfico sobre María Luisa Navarro Margati, profesora e pedagoga, cuxa formación e profesión forman parte do movemento de renovación español do primeiro terzo do século XX. O seu labor docente limítase ao Colexio Nacional de Xordomudos de Madrid (1912-1936). Nos anos 20 e 30 do século pasado colaborou na prensa madrileña, ademais de ser cofundadora e colaboradora do Boletín Escolar (1917) e da Revista de Pedagoxía (1922-1936). Ao mesmo tempo, destaca como tradutora e comentarista de autores limitados á Escuela Nueva. É unha das poucas mulleres que logrou facerse visible na Segunda República Española; visibilidade que lle custará o exilio. Residirá uns anos en Inglaterra, lonxe da vida profesional. Non obstante, o exilio arxentino permitiralle recuperalo: conferencias, cursos, cátedra universitaria en Tucumán e de novo o mundo editorial a través de Losada. Pouco antes da súa morte, abandonou as tarefas docentes para dedicarse de novo ao traballo social (como fixo nos anos republicanos e moi brevemente en Inglaterra): funda e dirixe a Comisión Democrática Española de Axuda (1945), para axudar aos refuxiados españois no sur de Francia.
[en] Introduction: The available models of pharmacogenetic implementation with NGS (Next Generation Sequencing) technologies are scarce thus limiting their incorporation in healthcare processes. Hypothesis: A pharmacogenetic approach integrating NGS techniques, information technologies and clinical knowledge allow its application in health care. Objectives: To develop an NGS pharmacogenetic platform and a knowledge base for healthcare implementation. Analytical validation and clinical performance evaluation. Material and methods: A capture enrichment (SureSelect-XT, Agilent®) and paired-end sequencing (Illumina®) process was developed together with bioinformatics tools and a knowledge repository for the interpretation of genomic results. Analytical validation was performed with control samples from cell lines characterized on multiple pharmacogenetic platforms. Clinical performance evaluation was conducted in a cohort of 395 patients with rheumatic diseases. Results: Analytical sensitivities and specificities >99% were obtained. The individuals studied harbored variants of interest in an average of 5 of 20 genes analyzed and a median of 34 drugs per patient (26% of the total evaluated) that would require an alternative therapeutic approach due to their genotype. Conclusions: The developed platform demonstrated adequate analytical performance parameters and clinical performance for its implementation in healthcare. In addition, the importance of pharmacogenetics as a tool for rational drug use is corroborated.

[gl] Introdución: Os modelos dispoñibles para a implantación farmacoxenética con tecnoloxías de secuenciación de nova xeración, ou NGS polas súas siglas en inglés, son escasos, limitando a súa incorporación nos procesos asistenciais. Hipótese: Un enfoque farmacoxenético que integre técnicas de NGS, tecnoloxías da información e coñecementos clínicos permite a súa aplicación sanitaria. Obxectivos: Desenvolver unha plataforma farmacoxenética NGS e unha base de coñecemento para a implantación sanitaria. Validación analítica e avaliación do rendemento clínico. Material e métodos: Desenvolveuse un proceso de enriquecemento de captura (SureSelect-XT, Agilent®) e unha secuenciación de extremos pareados (Illumina®) xunto con ferramentas bioinformáticas e un repositorio de coñecemento para a interpretación dos resultados xenómicos. Realizouse a validación analítica con mostras control de liñas celulares caracterizadas en múltiples plataformas farmacoxenéticas. A avaliación do rendemento clínico realizouse nunha cohorte de 395 pacientes con enfermidades reumáticas. Resultados: Obtivéronse sensibilidades e especificidades analíticas >99%. Os individuos estudados albergaron variantes de interese nunha media de 5 dos 20 xenes analizados e unha mediana de 34 fármacos por paciente (26% do total avaliado) que requirirían un enfoque terapéutico alternativo debido ao seu xenotipo. Conclusións: a plataforma desenvolvida demostrou uns parámetros de rendemento analítico e de rendemento clínico adecuados para a súa implementación sanitaria. Ademais, corrobórase a importancia da farmacoxenética como ferramenta para o uso racional dos medicamentos.
[en] The hyperbolic paraboloid structures have undeniable advantages when used as modular elements. However, there is a certain lack of knowledge about geometric principles which determine the structural behavior of these surfaces, which causes a shortage of examples. The main contribution of this research lies in proposing a hyperbolic paraboloid cover piece that can be used as a modular element, enjoying advantages such as structural efficiency under stable equilibrium conditions, high aesthetic value or costs and supplies wastage reductions. Based on the basic element aforementioned, a series of experiments have been performed assembling several basic elements and making slight variations on its geometries, resulting three types of structures: awnings, sheds and porticoes

[gl] As estruturas en paraboloide hiperbólico posúen unhas vantaxes que resultan innegables cando se usan como elementos modulares. Con todo existe, en certa medida, un descoñecemento dos principios xeométricos determinantes do comportamento estrutural destas superficies, o que incide na escaseza de exemplos existentes. O aporte fundamental desta investigación radica na proposta dunha peza de cuberta en paraboloide hiperbólico que poda ser usada como un elemento modular, e que goce de vantaxes tales como: eficiencia estrutural baixo condiciones de equilibrio estable, alto valor estético ou redución dos costos e cantidades de material. A partires do módulo base realízanse una serie de experimentos mediante distintos modos de agrupación das pezas e pequenas variacións nas súas xeometrías, que dan como resultado tres tipos de estructuras: marquesiñas, cubertos e pórticos.
[en] There are a lot of external morphological human characters which differentiate us from each other. These will depend on their genetic expression that is conditioned by environmental factors, character, etc. In this work we study two in particular, the 2D:4D ratio (difference in length between the index finger and the ring finger of each hand) and the 1D: 2D ratio (size difference between the first toe and the second toe). These four ratios will be compared in two populations: the first randomly sampled and formed by 30 individuals, where we will compare each ratio according to sex, the tendency to be left or right handed and depending on each side of the body; the second one consist in a three generation family where we will analyze this traits as in the previous one. The results reflect that there are no significant differences between the left members and the right based on the analyzed individuals. In addition, it is also verified that there is no association between the ratios studied and the variables with which they were compared.

[gl] A diversidade na aparencia humana responde principalmente á gran cantidade de caracteres morfolóxicos externos que presentamos como especie. Estes, á súa vez, dependen da súa expresión xenética, condicionada por factores ambientais, o carácter, etc. Neste traballo estudaranse dous en concreto, o ratio 2D:4D (diferenza de lonxitude entre o dedo índice e o dedo anular de cada man) e o ratio 1D:2D (diferenza de tamaño entre o primeiro dedo do pé e o segundo). Compararanse estes ratios das catro extremidades do noso corpo en dúas poboacións: a primeira mostreada ó azar formada por 30 individuos, nela analizaranse cada ratio en función do sexo, da tendencia a ser zurdo ou destro e en función de cada lado do corpo; a segunda fórmana una familia con tres xeracións onde estudaremos a influencia dos mesmos rasgos comentados anteriormente. Os nosos resultados reflicten que non existen diferenzas significativas entre os membros esquerdo e dereito a partires dos individuos analizados. Ademais conclúese que non existe una asociación entre os ratios estudados e as variables coas que se comparaban.
[en] The Constitutional jurisprudence is a reference to different agencies that form part of the Judicial System. This is why it is necessary to discuss it widely, paying special attention before introducing any change on it. The present study deals with a particular jurisprudential change that has taken place in 2016 related to video-surveillance and the fundamental rights of the workers subjected to them, based on the sentence that has prompted this change

[gl] A xurisprudencia constitucional é un referente para os distintos órganos que compoñen o poder xudicial, polo que calquera cambio nela debe ser obxecto de análise e de especial atención. Así, neste estudo trátase un cambio xurisprudencial que tivo lugar en 2016 a respecto da videovixilancia e os dereitos fundamentais dos traballadores que se ven sometidos a ela, con base na sentenza do Tribunal Constitucional que o propiciou
[en] This paper aims at studying the interpolated refrain phenomenon. We will briefly approach the first, though exiguous, Provençal texts, in order to focus, then, on the three love poems by D. Dinis, where the aforementioned phenomenon occurs. Furthermore, we will refer to some of the other compositions of the Portuguese king, that we consider relevant for this case study. It must be taken into account that the number of compositions that show an interpolated refrain in the Galician-Portuguese medieval lyric corpus hardly exceeds fifty poems. This is why we consider the great use D. Dinis makes of this rhetorical device, that appears in thirteen poems of his authorship, to be outstanding. In this sense, the fact that the troubadour king uses interpolated refrains in such a high number of compositions could be seen as the definitive evidence of Afonso III, 'O Bolonhês' responsibility in the introduction of this rhetorical device in Galician-Portuguese lyric.

[gl] Este artigo pretende abordar o fenómeno trobadoresco do refrán intercalar. Deste modo, achegarémonos brevemente aos primeiros, aínda que exiguos, testemuños provenzais, para, a seguir, centrar a nosa atención na análise das tres cantigas de amor do rei Don Denís en que se desenvolve o citado fenómeno. Tamén faremos referencia a algunha outra composición do rei que consideremos relevante para o presente traballo. Debemos ter en conta que, no corpus da lírica medieval galego-portuguesa, o número de composicións que presentan refrán intercalar supera escasamente o medio centenar, razón por que consideramos destacábel o amplo uso que Don Denís fai deste recurso, xa que o inclúe en trece das súas poesías. Neste sentido, o feito de o rei-trobador recorrer ao refrán intercalar nun número tan elevado de cantigas podería ser o indicio definitivo que probase a responsabilidade do seu pai, Afonso III 'O Bolonhês', na introdución deste artificio na lírica galego-portuguesa
