Metodología para Incluir en las Cátedras la Vinculación con la Comunidad. Perspectiva del Diseño e Innovación Social
Authors: Vásquez Coisme Ladys 
Published: December 2024

La Pontificia Universidad Católica de Ecuador Sede Esmeraldas está al servicio de la comunidad, apoyando por medio de sus carreras al desarrollo social y económico de los grupos más vulnerables de la localidad.
Este estudio tiene la finalidad de explicar de forma descriptiva la metodología aplicada en la carrera de diseño gráfico para involucrar en asignaturas de diferentes niveles proyectos de clase, encaminados a satisfacer la necesidad de un grupo de la comunidad acorde al Plan Anual de la carrera.
Para conseguir los resultados esperados se desarrolló un proceso compuesto de varios pasos, que permitieron una intervención dinámica y versátil, involucrando a diferentes actores de la vinculación como: responsables de vinculación de la carrera, responsables de proyectos, docentes de apoyo, estudiantes y beneficiarios directos.
La metodología para la aplicación de este proceso, inició a partir de reuniones que integraban a diferentes estamentos como: la dirección de vinculación de la PUCE-Esmeraldas, dirección de la escuela de diseño gráfico, responsables de proyectos, docentes de apoyo y estudiantes. Entre las actividades planteadas estaban las visitas de observación, así como mesas de trabajo estructuradas por; el responsable de vinculación y de proyectos, en otro caso, los responsables de los proyectos y los docentes de apoyo. Posteriormente se realizaron conversatorios entre docentes de apoyo y estudiantes. Adicionalmente, se dieron entrevistas con los beneficiarios.
Como resultado de esta metodología se obtuvo que el 66% de los estudiantes de la carrera realizaron vinculación con la comunidad dentro de sus actividades académicas y del porcentaje restante, el factor predominante fue que pertenecían al primer nivel. Por otro lado, el 100% de los docentes designados a este proceso, cumplieron sus asignaciones. También se incorporó voluntariamente una docente, lo que incidió oportuna y positivamente en las acciones como parte de la vinculación.
Como conclusión la aplicación de esta metodología permitió que tanto docentes como estudiantes pudieran cumplir con la vinculación dentro de sus jornadas académicas permitiendo el trabajo autónomo al servicio de sectores desfavorecidos de la sociedad. De la misma forma se identificó que a los estudiantes de 1er nivel y los que tomaban de una a cinco asignaturas en diferentes niveles, no participaron en las actividades de vinculación, impidiendo que aportaran a los objetivos planteados en el proyecto.

Published: December 2024

Se presenta el caso de una paciente femenina de 40 años que llegó a la guardia del Hospital Oftalmológico Pedro Lagleyze por una disminución abrupta de la visión en su ojo derecho asociado al hallazgo de un glaucoma de ángulo estrecho no tratado. Se realizaron los exámenes pertinentes que incluyeron tomografía de coherencia óptica y angiografía por tomografía de coherencia óptica que revelaron lesiones maculares típicas compatibles con maculopatía media aguda paracentral (MMAP). Un mes después de recibir tratamiento adecuado, la paciente logró recuperar la agudeza visual aunque con un adelgazamiento de las capas medias de la retina como secuela. La MMAP puede estar asociada no solo con trastornos vasculares retinales sino también con isquemia retinal provocada por elevaciones agudas en la PIO. Este informe de caso sugiere que este último mecanismo puede ser parte de la fisiopatogenia de la MMAP. Las imágenes SD-OCT macular son esenciales para la identificación de lesiones en sus etapas de edema y atrofia, y deben considerarse en pacientes con disminución de la agudeza visual tras episodios de hipertensión ocular.

Det umuliges muligheder
Authors: Grue Rune David 
Published: December 2024

Artiklen er baseret på interviews med en række scenekunstnere, som alle har beskæftiget sig med det, jeg kalder “umulige” bearbejdelser – noget, jeg også selv har været optaget af i mit arbejde som instruktør og bearbejder. I artiklen forsøger jeg, eksemplificeret gennem de interviewedes praktiske erfaringer, at identificere nogle af de udfordringer, som kan gøre et materiale særligt vanskeligt at omsætte til scenen og få bearbejdelsesopgaven til at forekomme “umulig”. Artiklen beskæftiger sig med, hvilke kunstneriske strategier, de interviewede har brugt i mødet med disse udfordringer, og viser, hvordan netop det “umulige” i et materiale potentielt kan bruges som kunstnerisk brændstof. Artiklen er skrevet som del af mit KUV-projekt Umulige Bearbejdelser, støttet af Kulturministeriet.

The article is based on interviews with theatre artists, who have all dealt with what I would call “impossible” adaptations – something that I myself have been interested in as a director and adapter. In the article, using examples from the practical experiences of the interviewees, I try to identify some of the challenges which can make a material particularly difficult to transform to the stage, and make the task of adaptation seem “impossible”. The article deals with artistic strategies that the interviewees have used to confront these challenges and shows how precisely the “impossible” aspects of a material potentially can be used as artistic fuel. The article has been written as part of my artistic research project Impossible Adaptations, funded by the Danish Ministry of Culture.
« Combattre d’égale à égal »
Authors: Beauchez Jérôme , Mattont Josselin 
Published: December 2024

Au tournant des années 2000, les ethnographes ont investi les sports de combat — à commencer par la boxe — comme un laboratoire d’étude des dominations masculines et des résistances féminines éprouvées dans l’expérience du corps-à-corps. Une majorité d’études a souligné la subalternité paradoxale des combattants, aussi souvent dominants au regard de leurs aptitudes aux affrontements physiques que dominés en termes de position socio-raciale. La description de ces masculinités dominantes/dominées a dès lors guidé celle des hégémonies masculines dans les sports de combat. Par contraste, les ethnographes qui ont décrit les féminités combattantes les ont souvent observées et comprises du point de vue d’un « féminisme physique » majoritairement promu par des femmes blanches issues des classes moyennes intellectuelles. Qu’en est-il des combattantes subalternisées, de leur engagement physique et du sens qu’elles donnent à leurs épreuves de l’adversité, dans et au-delà du corps-à-corps ? C’est tout l’enjeu de cet article que d’apporter des réponses à cette question, aussi insuffisamment documentée par l’ethnographie que propice à interroger non seulement les féminités, mais le « féminisme pragmatique » des combattantes qui résistent quotidiennement aux dominations — de genre, de classe et de race — au travers de leur engagement dans une lutte inséparablement physique et sociale.
Du sens et de la connaissance en anthropologie
Authors: Jarousseau Hélène 
Published: December 2024

La discipline anthropologique, née en Occident, s’est développée dans le contexte des empires coloniaux. Elle s’est donné pour tâche de rendre compte de la diversité des sociétés et des cultures humaines ainsi que de l’unité de l’homme. Au lendemain de la Seconde Guerre mondiale, les colonies accèdent à l’indépendance. Cette situation amène une nouvelle génération d’anthropologues à renouveler profondément la perspective, en soulignant l’asymétrie des rapports entre sociétés colonisatrices et colonisées. La diversité masquerait les inégalités. Ancienne colonie française, devenue département français d’outre-mer en 1946, la société réunionnaise s’inscrit dans les enjeux des empires coloniaux européens ayant engendré localement de fortes inégalités sociales et culturelles. Mais ce n’est qu’à partir des années 1970 que les premiers travaux anthropologiques à La Réunion se sont développés. Cet article propose d’explorer ces derniers en les confrontant aux contextes dans lesquels ils ont pris naissance pour mieux appréhender les savoirs qui en ont résulté. Cette démarche a permis de mettre au jour les biais analytiques qui ont caractérisé mes travaux. Le travail de déconstruction réalisé interroge les connaissances produites sur la période 1970-2000 sans renoncer à concevoir et à utiliser des outils au service d’une connaissance heuristique.
Engineered Polymersomes for the Treatment of Fish Odor Syndrome: A First Randomized Double Blind Olfactory Study

Published: March 2020

AbstractTrimethylamine (TMA) is a metabolite overtly present in patients suffering from trimethylaminuria (TMAU), a rare genetic disorder characterized by a strong “fishy” body odor. To date, no approved pharmacological treatment to sequester excess TMA on the skin of patients exists. Here, transmembrane pH gradient poly(isoprene)‐block‐poly(ethylene glycol) (PI‐b‐PEG) polymersomes are investigated for the topical removal of TMA. PI‐b‐PEG amphiphiles of varying chain length are synthesized and evaluated for their ability to form vesicular structures in aqueous media. The optimization of the PI/PEG ratio of transmembrane pH gradient polymersomes allows for the rapid and efficient capture of TMA both in solution and after incorporation into a topical hydrogel matrix at the pH of the skin. A subsequent double blind olfactory study reveals a significant decrease in perceived odor intensity after application of the polymersome‐based formulation on artificial skin substrates that has been incubated in TMA‐containing medium. This simple and novel approach has the potential to ease the burden of people suffering from TMAU.

Published: March 2020

AbstractGraphdiyne (GDY), a rising star of 2D carbon allotropes with one‐atom‐thick planar layers, has achieved the coexistence of sp‐ and sp2‐hybridized carbon atoms in a 2D planar structure. In contrast to the prevailing carbon allotropes, GDY possesses Dirac cone structures, which endow it with unique chemical and physical properties, including an adjustable inherent bandgap, high‐speed charge carrier transfer efficiency, and excellent conductivity. Additionally, GDY also displays great potential in photocatalysis, rechargeable batteries, solar cells, detectors, and especially electrocatalysis. In this work, various GDY‐supported electrocatalysts are described and the reasons why GDY can act as a novel support are analyzed from the perspective of molecular structure, electronic properties, mechanical properties, and stability. The various electrochemical applications of GDY‐supported electrocatalysts in energy conversion such as hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, overall water splitting, and nitrogen reduction reaction are reviewed. The challenges facing GDY and GDY‐based materials in future research are also outlined. This review aims at providing an in‐depth understanding of GDY and promoting the development and application of this novel carbon material.

AbstractCrop yield prediction is a critical measurement, especially in the time when parts of the world are suffering from farming issues. Yield forecasting gives an alert regarding economic trading, food production monitoring, and global food security. This research was conducted to investigate whether active optical sensors could be utilized for potato (Solanum tuberosum L.) yield prediction at the mid.le of the growing season. Three potato cultivars (Russet Burbank, Superior, and Shepody) were planted and six rates of N (0, 56, 112, 168, 224, and 280 kg ha−1), ammonium sulfate, which was replaced by ammonium nitrate in the 2nd year, were applied on 11 sites in a randomized complete block design, with four replications. Normalized difference vegetation index (NDVI) and chlorophyll index (CI) measurements were obtained weekly from the active optical sensors, GreenSeeker (GS) and Crop Circle (CC). The 168 kg N ha−1 produced the maximum potato yield. Indices measurements obtained at the 16th and 20th leaf growth stages were significantly correlated with tuber yield. Multiple regression analysis (potato yield as a dependent variable and vegetation indices, NDVI and CI, as independent variables) could make a remarkable improvement to the accuracy of the prediction model and increase the determination coefficient. The exponential and linear models showed a better fit of the data. Soil organic matter content increased the yield significantly but did not affect the prediction models. The 18th and 20th leaf growth stages are the best time to use the sensors for yield prediction.

AbstractBackgroundWorkers employed in the coal mining sector are at increased risk of respiratory diseases, including coal workers' pneumoconiosis (CWP). We investigated the prevalence of CWP and its association with sociodemographic factors among Medicare beneficiaries.MethodsWe used 5% Medicare Limited Data Set claims data from 2011 to 2014 to select Medicare beneficiaries with a diagnosis of ICD‐9‐CM 500 (CWP). We aggregated the data by county and limited our analysis to seven contiguous states: Illinois, Indiana, Kentucky, Ohio, Pennsylvania, Virginia, and West Virginia. We estimated county‐level prevalence rates using total Medicare beneficiaries and miners as denominators and performed spatial hotspot analysis. We used negative binomial regression analysis to determine the association of county‐wise sociodemographic factors with CWP.ResultsThere was significant spatial clustering of CWP cases in Kentucky, Virginia, and West Virginia. Spatial clusters of 210 and 605 CWP cases representing an estimated 4200 to 12 100 cases of Medicare beneficiaries with CWP were identified in the three states. Counties with higher poverty levels had a significantly elevated rate of CWP (adjusted rate ratios [RR]: 1.15; 95% CI, 1.12‐1.18). There was a small but significant association of CWP with the county‐wise catchment area. Rurality was associated with a more than three‐fold elevated rate of CWP in the unadjusted analysis (RR: 3.28, 95% CI, 2.22‐4.84). However, the rate declined to 1.45 (95% CI, 1.04‐2.01) after adjusting for other factors in the analysis.ConclusionsWe found evidence of significant spatial clustering of CWP among Medicare beneficiaries living in the seven states of the USA.
Tunable Polycyclic Chiral Beams
Authors: Lan Yanping , Qian Yixian , Ren Zhijun 
Published: March 2020

AbstractThe generation of polycyclic chiral beams by inducing annular spiral zone phases that consist of multiple subphases is numerically and experimentally demonstrated. Each subphase is composed of a spiral phase, an equiphase, and a radial phase. The number and twisting direction of the spiral intensity lobes for every layer could be individually controlled. Furthermore, the orientations for the twisting lobes could be tuned by changing the introduced equiphase gradient. More importantly, such optical fields also show rotation property when the equiphases with gradient are dynamically and continuously imposed. This advantage of rotation also brings about the possibility of such chiral beams to rotate particles. Such beams would be advantageous for manufacturing tunable chiral metamaterials and have potential applications in optical tweezers and optical communication.

AbstractBiocomposites from poly(lactic acid) (PLA) and grape pomace (GP) were created via injection molding to examine the effects of GP in a PLA matrix. To optimize the mechanical performance the biocomposites were compatibilized with maleic anhydride grafted PLA (MA‐g‐PLA). The objective of this work was to create a model that could accurately predict the mechanical properties of GP/PLA biocomposites. A region of feasibility for the biocomposites was determined using a statistical design of experiments. Linear regression was used to model the mechanical performance and predicted results with an error of 10% for both tensile and flexural strength and 16% for impact strength. The model was verified with a biocomposite of PLA/GP/MA‐g‐PLA with a ratio of 62/36/2. This biocomposite had a tensile strength, flexural modulus, and impact strength of 25.8 MPa, 40.0 MPa, and 18.4 J/m, respectively. It was found that a linear model can accurately predict the mechanical properties of PLA/GP/MA‐g‐PLA biocomposites.
Experimentelle Untersuchungen zu lochrandgestützten Flachdecken mit Durchstanzbewehrung

Published: March 2020

AbstractZur Vermeidung eines Durchstanzversagens konventionell gelagerter Flachdecken wurden in den vergangenen Jahrzehnten auf Grundlage umfangreicher experimenteller Untersuchungen verschiedene Bemessungskonzepte erarbeitet und in Regelwerken verankert. Flachdecken mit einer Lochrandstützung und der damit verbundenen reduzierten Lasteinleitungsfläche fanden in diesen Bemessungskonzepten bislang keine Berücksichtigung. Vorangegangene experimentelle und numerische Untersuchungen zeigten das unterschiedliche Tragverhalten von Vollplatten und lochrandgestützten Platten. Es wurde festgestellt, dass infolge dieser Unterschiede im Rahmen der normativen Nachweisführung die Durchstanztragfähigkeit in Abhängigkeit von der konstruktiven Durchbildung der Anschlussstelle Stütze‐Flachdecke überschätzt werden kann. Aus den Untersuchungsergebnissen resultierte die Fragestellung, welche traglaststeigernde Wirkung durch den Einbau von Durchstanzbewehrung bei lochrandgestützten Platten mit kleiner Lasteinleitungsfläche erzielt werden kann. Zur Untersuchung dieser Frage wurde anknüpfend an die vorangegangenen Versuche an einem Plattenausschnitt mit einer Durchstanzbewehrung aus Dübelleisten ein Tastversuch durchgeführt. Nachfolgend wird über die Ergebnisse dieses Versuchs berichtet und ein Vergleich mit den Resultaten der vorangegangenen Untersuchungen vorgenommen.

Published: March 2020

AbstractSlim floor structures greatly increase the sustainability. Height of the buildings will be lower, while commercially available connections can help to design structures that can be dismantled later for re‐use. Choosing products that utilise recycled raw materials and building methods that accommodate low emission materials such as wood will result in even lower CO2 emissions.
