En Chile existe una progresiva precarización de la profesión docente (Ruffinelli, 2016) agravada por la actual crisis sanitaria COVID 19. En este contexto, la implementación de la educación a distancia ha tenido múltiples consecuencias para el profesorado (Villalobos Muñoz, 2021) y, particularmente para las mujeres, quienes deben hacer coexistir su rol de docente con el trabajo doméstico y de cuidados, complejizando la ya difícil conciliación laboral y familiar. Desde estas bases, este artículo tiene como objetivo analizar, desde una perspectiva de género, la situación de precariedad que vivencian profesoras de educación infantil y educación primaria en Chile y, además, conocer cómo dicha situación se ha agravado en el contexto de la pandemia. Para lograr este objetivo, se realizó un estudio cualitativo en base a entrevistas semiestructuradas a nueve profesoras de educación infantil y primaria de la Provincia de Valparaíso. Los principales resultados indican que la condición laboral ya precarizada se ha visto agudizada por la falta de recursos materiales, técnicos y procedimentales con los que se enfrentan a la docencia online. Por otro lado, la difuminación de fronteras entre el mundo laboral remunerado y los cuidados, como parte de las consecuencias del teletrabajo y de las propias relaciones de género tradicionales, ha generado una sobrecarga física y emocional para las profesoras. Finalmente, se da cuenta de que la gestión de las autoridades educativas y de las escuelas durante la pandemia, es visualizada por parte de las entrevistadas como incongruente con la realidad, tanto del profesorado como del estudiantado chileno.

Resumen (analítico) Se presenta una investigación sobre el ciclo de movilizaciones feministas universitarias de 2018, en la cual jóvenes estudiantes chilenas denunciaron violencia y acoso en instituciones de educación superior. Se visibiliza que la violencia contra las mujeres ha sido normalizada e invisibilizada, pues se encuentra arraigada en una cultura sexista. Así, se propone un objetivo doble: por un lado, identificar cuáles manifestaciones de la violencia de género fueron las principales catalizadoras de dichas movilizaciones; y, por otro, determinar cómo tales violencias se expresan en los contextos universitarios desde la voz de sus protagonistas. Este movimiento introdujo críticas profundas a la concepción de educación superior y acabó por revelarla como un campo de continua disputa política articulada con la genealogía del movimiento estudiantil chileno y con el resurgimiento de feminismos jóvenes en Latinoamérica. Abstract (analytical) This research focuses on the 2018 cycle of feminist mobilizations at univiersities in which young female Chilean students denounced violence and harassment in higher education institutions, highlighting that violence against women has been normalized and made invisible as it is rooted in the dominant sexist culture. A double objective was proposed for the study: identify which manifestations of gender-based violence were the main catalyst for these mobilizations; and determine how this violence is expressed in university contexts based on the voices of the protagonists of the mobilizations. This movement involved strong criticism to the conception of higher education, revealing it as a field of continuous political dispute that is articulated with the genealogy of the Chilean student movement and the resurgence of expressions of feminism by young people in Latin America. Resumo (analítico) É apresentada uma investigação sobre o ciclo 2018 de mobilizações feministas universitárias, em que jovens estudantes chilenas denunciaram violência e assédio em instituições de ensino superior; tornar visível que a violência contra a mulher foi normalizada e invisibilizada, por tanto, está enraizada em uma cultura sexista. Assim se propõe um duplo objetivo: por um lado, identificar quais as manifestações de violência de gênero foram os principais catalisadores dessas mobilizações; e, de outro, determinar como tal violência se expressa em contextos universitários a partir da voz de suas protagonistas. Este movimento introduz críticas profundas à concepção de ensino superior e acabou revelando-a como um campo de contínua disputa política articulada com a genealogia do movimento estudantil chileno e com o ressurgimento de jovens feminismos na América Latina.

Resumen: En este articulo nos proponemos reflexionar en torno a tres ejes analiticos clave de la epistemologia feminista con los cuales es posible abordar el pensamiento de las ciencias sociales del sur global. Primero, examinaremos el denominado punto de vista feminista. Segundo, revisamos las principales lineas del feminismo decolonial, y tercero, concluimos con los feminismos negros e interseccionalidad. Nuestro interes es presentar sinteticamente estos lineamientos que, desde una perspectiva feminista, trascienden las dicotomias analiticas de los estudios de genero, y permiten comprender la multiplicidad de experiencias dadas por los contextos de mujer/raza/clase. Estos tres enfoques pueden dialogar y enriquecer una produccion de conocimiento tradicionalmente eurocentrista y sexista, para contribuir a los supuestos que no solo emergen de los estudios feministas, sino que de la investigacion social en general.

[EN] Background and objectives: Thermal ablation of tumors plays a key role to fight cancer, since it is a minimally invasive treatment which involves some advantages compared to surgery and chemotherapy, such as shorter hospital stays and consequently lower costs, along with minor side effects. In this context, computational modeling of heat transfer during thermal ablation is relevant to accurately predict the obtained ablation zone in order to avoid tumor recurrence risk caused by incomplete ablation, and the same time to save the surrounding healthy tissue. The aim of this work is to develop a more realistic porous media-based mathematical model to simulate a microwave thermal ablation (MWA) of an in vivo liver tumor surrounded by healthy tissue. Methods: The domain is made up of a spherical tumor bounded by a cylindrical healthy liver tissue. The simulated microwave antenna is a 14 G HS Amica-Gen Probe, and the supplied power of 60 W is applied for 300 s and 600 s. The model consists in coupling modified Local Thermal Non Equilibrium (LTNE) equations with the electromagnetic equations. The LTNE equations include a variable porosity function which fits the porosity changing from the tumor core to the rim based on experimental measures in in vivo cases. Moreover, four different blood vessels' uniform distributions are investigated to compare the effects of different vascularizations of the considered target tissue. Results: The results are shown in terms of temperature fields, ablation diameters and volumes based on the Arrhenius thermal damage model with 99% of cell death probability. The outcomes show a very good agreement with a clinical study on human patients with hepatocellular carcinoma using the same antenna and energy setting, when terminal arteries distribution is included. Conclusions: In this work, an in vivo microwave ablation of liver tumor surrounded by healthy tissue is modeled with a variable-porosity medium approach based on experimental measures. The outcomes shown for distinct vascularizations underline the key relevance of modeling more and more accurately tumor MWA, by considering increasingly realistic features, avoiding tumor recurrence, and improving both medical protocols and devices.

[EN] Microwave (MWA) and radiofrequency ablation (RFA) are main ablative techniques for hepatocellular carcinoma (HCC) and colorectal liver metastasis (MT). This randomized phase 2 clinical trial compares the effectiveness of MWA and RFA as well as morphology of corresponding ablation zones. HCC and MT patients with 1.5-4 cm tumors, suitable for ablation, were randomized into MWA or RFA Groups. The primary endpoint was short-to-long diameter ratio of ablation zone (SLR). Primary technical success (TS) and a cumulative local tumor progression (LTP) after a median 2-year follow-up were compared. Between June 2015 and April 2020, 82 patients were randomly assigned (41 patients per group). For the per-protocol analysis, five patients were excluded. MWA created larger ablation zones than RFA (p = 0.036) although without differences in SLR (0.5 for both groups, p = 0.229). The TS was achieved in 98% (46/47) and 90% (45/50) (p = 0.108), and LTP was observed in 21% (10/47) vs. 12% (6/50) (OR 1.9 [95% CI 0.66-5.3], p = 0.238) of tumors in MWA vs. RFA Group, respectively. Major complications were found in 5 cases (11%) vs. 2 cases (4%), without statistical significance. MWA and RFA show similar SLR, effectiveness and safety in liver tumors between 1.5 and 4 cm., This work was supported by a grant for medical research from Spanish Government (FIS-PI12/00799) and by the Spanish Ministerio de Ciencia, Innovacion y Universidades under "Programa Estatal de I+D+i Orientada a los Retos de la Sociedad", Grant RTI2018-094357-B-C21.

In the last few years, we have been exploring the use of transparent nanocrystalline yttria-stabilized zirconia (nc-YSZ) ceramics as a biomedical transparent cranial implant, referred as the "Window to the Brain" (WttB). The WttB aims at providing chronical optical access to the brain for diagnostics and therapeutic procedures and it has shown to provide an effective means to obtain enhanced results from optical imaging techniques. The objective of this work is to explore the photothermal effects of the Wttb produced when it is irradiated by a laser source.We make experimental and computer models. The thermal effects of laser irradiation on the nc-YSZ samples were evaluated upon registering the induced temperature changes by means of thermal imaging. The computer models try to mimic the experimental models using a similar geometry, reproducing the physical situation by a couple thermal-optical problem and adjusting the main parameters from the experimental results.Experimental and computational coincides in results: Temperatures at the bottom surface of the implant does not exceed those which produce thermal damage. The quantitative comparison between experimental and computational models show that differences in results are under a reasonable value of 5% and qualitatively we observe a similar behavior. The results provide optimum values for the thermal-optical nc-YSZ parameters considering a linear and exponential relationship with temperature for the absorption coefficient: The thermal conductivity is k = 2.13 W/m·K and the absorption coefficient α varies from 426 to 526 mThe temperatures achieved in the nc-YSZ during the laser irradiation are suitable for biomedical applications. The combination of experimental and computational models contributes to build a clinically oriented model with the thermal-optical parameters values stablished and to determine their influence in results. Specifically, the absorption coefficient of the nc-YSZ samples is the most influent parameter in the obtained temperatures. Moreover, this combination provides a method to evaluate the relevant thermal-optical parameters of nc-YSZ samples obtained with different manufacturing processes.

Pregraduate students often have low success expectations toward their thermodynamics courses, which are often considered too abstract and remarkably difficult to understand. For this reason, they may not even try to reach any level of comprehension while settling for reproducing mathematical calculations and memorizing definitions to pass the exams. Traditional lectures on thermodynamics, focusing on mathematical deductions while neglecting the qualitative characterization of the concepts behind the equations, do not help in this respect. Aiming at a change in the teaching practice and focused on the second law of thermodynamics, the main goals of this work are to characterize the way of reasoning of the expert, to present a review on the most important learning difficulties encountered by students and categorize them into three groups: the disregard of qualitative understanding, the inherent conceptual difficulties, and those related to the students’ previous knowledge, and to propose some suitable teaching practices to assist instructors in this difficult but rewarding task.

Resumen La violencia de género atenta contra los derechos humanos de las mujeres más allá de su condición o procedencia. Este artículo presenta una investigación realizada en universidades chilenas durante 2019, que aborda, por medio de una metodología cualitativa, las experiencias de estudiantes universitarias que han vivenciado violencia de género ejercida por sus parejas. Con este objetivo, en primer lugar, se profundiza en las repercusiones emocionales que conlleva este tipo de violencia, así como las trayectorias y dificultades que las jóvenes deben enfrentar para conseguir finalizar las relaciones en que ha existido violencia. En segundo lugar, se analiza la incidencia de las redes de apoyo formales e informales con las que cuentan las jóvenes y los diversos niveles de confianza que estas proyectan. De manera preeminente, destacan aquellas redes que, desde dentro de los espacios educativos, fomentan la agencia y autonomía de las estudiantes y las impulsan a abandonar las relaciones con los agresores. Las experiencias recogidas visibilizan el papel ineludible que cabe a las instituciones de educación superior en la lucha contra la violencia de género.

[EN] The objective of this study was to compare three different heat transfer models for radiofrequency ablation of in vivo liver tissue using a cooled electrode and three different voltage levels. The comparison was between the simplest but less realistic Pennes' equation and two porous media-based models, i.e. the Local Thermal Non-Equilibrium (LTNE) equations and Local Thermal Equilibrium (LTE) equation, both modified to take into account two-phase water vaporization (tissue and blood). Different blood volume fractions in liver were considered and the blood velocity was modeled to simulate a vascular network. Governing equations with the appropriate boundary conditions were solved with Comsol Multiphysics finite-element code. The results in terms of coagulation transverse diameters and temperature distributions at the end of the application showed significant differences, especially between Pennes and the modified LTNE and LTE models. The new modified porous media-based models covered the ranges found in the few in vivo experimental studies in the literature and they were closer to the published results with similar in vivo protocol. The outcomes highlight the importance of considering the three models in the future in order to improve thermal ablation protocols and devices and adapt the model to different organs and patient profiles., This work was supported by the Spanish Ministerio de Economia, Industria y Competitividad under "Plan Estatal de Investigacion, Desarrollo e Innovacion Orientada a los Retos de la Sociedad", Grant No "RTI2018-094357-B-C21" and by the Italian Government MIUR Grant No "PRIN-2017F7KZWS".

The aim of this study is to identify aspects related to gender-based violence at Chilean universities, with a focus on three areas of analysis: the prevalence of violence against women in heterosexual relationships; the persistence of traditional gender constructs; and the reproduction of myths about this form of abuse, as well as the sexist imaginaries present in the student’s experiences. Theoretical support is drawn from feminist analyses that have examined the power structures in which these aggressions survive and reproduce, as well as the social dynamics that naturalize them. Studies have found that higher education is neither a protective factor against violence nor a tool that dismantles the gender imaginary that supports it. At a methodological level, 1,120 surveys were administered at three Chilean universities, encompassing the three aforementioned areas of analysis. The results point to the continuing prevalence of violence against women, as well as the endurance of myths and sexist imaginary that invisibilize the reproduction of gender power relations. The discussion and conclusions highlight the role of education and higher education institutions in driving changes in this area., Se presenta una investigación cuyo objetivo fue analizar aspectos relacionados con la violencia de género en el contexto universitario chileno abordando tres ejes en particular: prevalencia de violencia contra las mujeres en relaciones de pareja heterosexuales, pervivencia de constructos tradicionales de género, reproducción de mitos sobre este maltrato, así como imaginarios sexistas presentes en el estudiantado. El sustento teórico viene dado por los enfoques feministas que han examinado las estructuras de poder en las que permanecen y se reproducen estas agresiones, así como las dinámicas sociales que las naturalizan. Los estudios en el área destacan que la educación superior no es necesariamente un factor protector ante la violencia ni una herramienta que, de por sí, desmonte los imaginarios de género que le dan soporte. A nivel metodológico, se aplicaron 1.120 encuestas en tres universidades chilenas, en las que se abordaron los tres ejes de análisis ya señalados. Los resultados muestran un elevado porcentaje de violencia contra las mujeres y, a la vez, evidencian la subsistencia de mitos e imaginarios sexistas que invisibilizan la reproducción de este tipo de relaciones de poder. En la discusión y conclusiones, se releva el papel de la educación y de las instituciones de educación superior a la hora de promover cambios en este ámbito.

[EN] Radiofrequency (RF)-based monopolar (MM) and bipolar mode (BM) applicators are used to thermally create coagulation zones (CZs) in biological tissues with the aim of destroying surface tumors and minimizing blood losses in surgical resection. Both modes have disadvantages as regards safely and in obtaining a sufficiently deep coagulation zone (CZ). In this study, we compared both modes versus a switching monopolar mode (SMM) in which the role of the active electrode changes intermittently between the two electrodes of the applicator. In terms of clinical impact, the three modes can easily be selected by the surgeon according to the surgical maneuver. We used computational and experimental models to study the feasibility of working in MM, BM, and SMM and to compare their CZ characteristics. We focused exclusively on BM and SMM, since MM only creates small coagulation zones in the area between the electrodes. The results showed that SMM produces the deepest CZ between both electrodes (33% more than BM) and SMM did not stop the generator when an electrode lost contact with the tissue, as occurred in BM. Our findings suggest that the selective use of SMM and BM with a bipolar applicator offers greater advantages than using each type alone, This research was funded by the Spanish Ministerio de Ciencia, Innovacion y Universidades under the Programa Estatal de I+D+i Orientada a los Retos de la Sociedad, Grant No. RTI2018-094357-B-C21

[EN] The objective was to explore variations of temperature distribution and coagulation zone size computed by a two-compartment radiofrequency ablation (RFA) model when including simultaneously reversible changes in the tissue electrical conductivity (sigma) due to temperature and irreversible changes due to thermal coagulation. Two-compartment (tumor and healthy tissue) models were built and simulated. Reversible change of sigma was modeled by a piecewise function characterized by increments of +1.5%/degrees C up to 100 degrees C, and a 100 times smaller value from 100 degrees C onwards. Irreversible changes of sigma were modeled using an Arrhenius model. We assumed that both tumor and healthy tissue had a different initial sigma value (as suggested by the experimental data in the literature) and tended towards a common value as thermal damage progressed (necrotized tissue). We modeled a constant impedance protocol based on 90 V pulses voltage and three tumor diameters (2, 3 and 4 cm). Computer simulations showed that the differences between both models were only 0.1 and 0.2 cm for axial and transverse diameters, respectively, and this small difference was reflected in the similar temperature distributions computed by both models. In view of the available experimental data on changes of electrical conductivity in tumors and healthy tissue during heating, our results suggest that irreversible changes in electrical conductivity do not have a significant impact on coagulation zone size in two-compartment RFA models., This work was supported by the National Council of Science and Technology (CONACYT, Mexico) through a scholarship grant to Dora Luz Castro-Lopez, CVU registration No 446604; and by the Spanish Ministerio de Ciencia, Innovacion y Universidades under "Programma Estatal de I+D+i Orientada a los Retos de la Sociedad", Grant No "RTI2018-094357-B-C21".

En esta comunicación presentamos una experiencia sobre la formación en competencias, concretamente, para trabajar la comunicación efectiva. Realizamos un taller, de dos horas de duración, que tenía un carácter predominantemente práctico, aunque con alguna aportación teórica. En base a dos experiencias previas fuera de la docencia reglada, esta propuesta planteaba un triple interés: comprobar si era viable desarrollar el taller dentro de la docencia reglada, analizar el interés del alumnado en este tipo de formación, y comprobar la eficacia del taller en aras de una mejora de la calidad de las presentaciones del alumnado. Los resultados mostraron una satisfacción de la experiencia en todos estos ítems. Para poder obtener mejores resultados detectamos que el taller debe realizarse durante las primeras semanas del curso, para que así el desarrollo de las clases ordinarias suponga una práctica adicional sin necesidad de recurrir a sesiones especiales. In this communication, we present an experience on skills training. Specifically, we proposed a workshop to work the effective communication. The two-hours workshop was mainly practical, although some theoretical interventions were included. Based on two previous no formal teaching experiences, this proposal had a triple interest: to check if it was feasible to develop the workshop within formal teaching, to analyze the motivation of students towards this type of training, and to check the effectiveness of the workshop for the improvement in the quality of student presentations. The results showed a satisfaction of the experience in all these items. In order to obtain better results, it was detected that the workshop should be held during the first weeks of the course, so that the development of the classes involves additional practice without the need of special sessions.

[EN] Purpose: To improve the computer modelling of radiofrequency ablation (RFA) by internally cooled wet (ICW) electrodes with added clinically oriented features. Methods: An improved RFA computer model by ICW electrode included: (1) a realistic spatial distribution of the infused saline, and (2) different domains to distinguish between healthy tissue, saline-infused tumour, and non-infused tumour, under the assumption that infused saline is retained within the tumour boundary. A realistic saline spatial distribution was obtained from an in vivo pig liver study. The computer results were analysed in terms of impedance evolution and coagulation zone (CZ) size, and were compared to the results of clinical trials conducted on 17 patients with the same ICW electrode. Results: The new features added to the model provided computer results that matched well with the clinical results. No roll-offs occurred during the 4-min ablation. CZ transversal diameter (4.10 +/- 0.19 cm) was similar to the computed diameter (4.16 cm). Including the tumour and saline infusion in the model involved (1) a reduction of the initial impedance by 10 - 20 ohm, (2) a delay in roll-off of 20 s and 70 - 100 s, respectively, and (3) 18 - 31% and 22 - 36% larger CZ size, respectively. The saline spatial distribution geometry was also seen to affect roll-off delay and CZ size. Conclusions: Using a three-compartment model and a realistic saline spatial distribution notably improves the match with the outcome of the clinical trials., This work was supported by the Spanish Ministerio de Economia, Industria y Competitividad under the "Plan Estatal de Investigacion, Desarrollo e Innovacion Orientada a los Retos de la Sociedad" Grant TEC2014-52383-C3-R (TEC2014-52383-C3-1-R and TEC2014-52383-C3-3-R).

Resumen: Se presenta un estudio que exploró en las vivencias de maternidad de mujeres que ejercen la prostitución a nivel de vía pública. Así, se enfocó la maternidad como una institución social vinculada a imaginarios prescriptivos y a políticas de control de género; y a su vez, se entendió la prostitución como institución patriarcal que estigmatiza a las mujeres que la ejercen. En base al análisis de entrevistas en profundidad realizadas en Barcelona, los resultados dan cuenta que el ʻideal maternalʼ convive con el estigma de la prostitución, aunque no se interioriza negativamente, pues se desarrollan estrategias para gestionar la maternidad en el marco de una ʻvida ocultaʼ; sin embargo, también se vislumbra que esta gestión implica vivenciar experiencias muchas veces contradictorias en el marco del ejercicio de la prostitución. Summary: This paper presents a study that explored the experiences of motherhood in women who are involved in street prostitution. For this work, motherhood is focused as a socially constructed institution linked to prescriptive social imaginary and gender control policies; and, in turn, prostitution was understood as a patriarchal social institution where the associated stigma brands the experience of those women who exercise it. Based on the analysis of in-depth interviews conducted in Barcelona the results show that the ‘maternal ideal’ lives with the stigma of prostitution, although not negatively internalized as they have develop strategies to manage motherhood within a ʻhidden lifeʼ; however, it is also envisaged that this management involves living often contradictory experiences in the exercise of prostitution.

En esta comunicación presentamos una experiencia interdisciplinar realizada en la asignatura de Matemáticas 2 del Grado en Fundamentos de la Arquitectura de la Universitat Politècnica de València. La temática que utilizamos fue la relación entre función y forma. Concretamente, la experiencia conectaba las expresiones matemáticas que definen diferentes curvas cónicas y superficies cuádricas con su funcionalidad. La temática se desarrolló realizando seminarios, visitas y talleres, y se culminó con la realización de un trabajo en grupo cuyo objetivo era el diseño de las piezas de un ajedrez. La particularidad y principal característica del trabajo era que la representación de las curvas y superficies empleadas en el diseño se debía hacer únicamente utilizando las ecuaciones que definen estas formas. Los principales resultados de la experiencia se centraron en un aumento de la motivación, de la participación y del rendimiento del alumnado. In this communication we present an interdisciplinary experience carried out in the Metemáticas 2 subject which belongs to the Degree in Fundamentals of Architecture (Universitat Politècnica de València). We used as the main topic the relationship between function and form. Specifically, the experience we made related mathematical expressions which define different conical curves and quadric surfaces with their functionality. The topic was discussed by means of seminars, visits and workshops, and ended with a group work whose objective was the design of the chess pieces. The particularity and main characteristic of the work was that the representation of the curves and surfaces used in the design should only be done using the equations that define these forms. The main results of the experience focused on an increase in motivation, participation and student performance.
