        El recurso audiovisual como herramienta didáctica en la clase de español L2/LE : Ejemplo de propuesta didáctica con Diarios de motocicleta (2004)

        ( Arrayás Márquez José Antonio ) 한국스페인어문학회 2021 스페인어문학 Vol.- No.101

        This article begins by highlighting how integrating the work with audiovisual resources in the L2/LE class can facilitate the understanding of linguistic aspects and make the student cope more safely with lexical and grammatical content. It also points out how audiovisual material can increase student motivation, since it makes the target language and culture much more attractive and easier to decipher. This paper reflects on the convenience of bringing audiovisual resources to the language classroom, since for a long time the video materials that have been brought to L2/LE classes focused mainly on linguistic work, ignoring the cultural component present in all audiovisual production. Through the viewing of a movie or a chapter of a series, students are aware of other communicative aspects, such non-verbal language or socio-cultural aspects, wich are inserted in the real communication situations that we can find in the scenes. For all these reasons, the article shows that the cinema and other audiovisual materials are and should be first-rate didactic tool in L2/LE classes, since we can achieve in the classroom an integration of all skills fully contextualized: our students will read, listen, and speak in real communication situations. This work reviews the evolution of the use of audiovisual materials in the classroom, deals with the implications of the communicative approach and the exploitation of audiovisual resources, and explains the main advantages and disadvantages of working in language classes with audiovisual productions and how to select the most appropriate. Finally, three classroom activities are proposed to work with the movie Diarios de motocicleta (2004).

        Numerical analysis of a hydraulic gear micro motor

        Alberto Flores-Márquez,Fernando Velázquez-Villegas,Gabriel Ascanio 대한기계학회 2013 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.27 No.5

        This study investigates the critical parameters that have the most impact on the structural capacity of hydraulic gear micro motors,namely, motor configuration, output torque, and speed. Seven different motor configurations were evaluated in terms of output speed and torque, which depend on the number and size of gears. During motor operation, reactive loads generated by drag forces, viscous damping forces, and oil pocketing within two adjacent teeth in contact were numerically calculated. Stress analysis using the finite element method was also performed to evaluate the structure of the aforementioned gear motor configurations. The results demonstrated that the structural capacity of a hydraulic motor does not necessarily increase when using larger gears or by increasing the number of gears. Reactive loads increase as rotational speed and gear size increase. Higher lubricant pressure is also required to attain the required output torque and velocity.

        El desafío de traducir poesía coreana. La traducción al español de 하늘 우체국 - Casa de Correos Celestial (2019) del poeta Soo-Bok Kim

        José Antonio Arrayás Márquez 한국외국어대학교 통번역연구소 2020 통번역학연구 Vol.24 No.1

        The translation of literature often raises important problems of interpretation. But within the scope of translation, the translation to another language of poetry was always notable for its complexity. There is a widely extended topic of considering poetic language as intraducible, since we should not focus only on words, but also on the essence and soul of a genre, such as poetry, which has sometimes been labeled as something magical, ethereal and impossible to translate. Therefore, when we translate poetry we must bear in mind that the resulting text will not be an identical text to the original version, but a text transformed and adapted to the characteristics of its new readers. Poetry is more difficult to translate than prose, but also, if translation tasks are carried out between two extraordinarily distant languages, such as Korean and Spanish, the difficulties increase significantly. That is to say, such a translation work does not only require mastering the literal translation by the translator, but also requires a complete understanding of the regionalisms and connotations of the language of the source text and that of the target text. Through the study of the Spanish translation of 하늘 우체국 – Casa de Correos Celestial (2019) by the poet Soo-Bok Kim, a series of considerations and strategies are proposed to address this type of translation.

        The NER-related gene GTF2H5 predicts survival in high-grade serous ovarian cancer patients

        Javier Gayarre,Marta M. Kamieniak,Alicia Cazorla-Jiménez,Ivan Muñoz-Repeto,Salud Borrego,Jesús García-Donas,Susana Hernando,Luis Robles-Díaz,José M. García-Bueno,Ivan Márquez-Rodas,María José Echarri 대한부인종양학회 2016 Journal of Gynecologic Oncology Vol.27 No.1

        Objective: We aimed to evaluate the prognostic and predictive value of the nucleotide excision repair-related gene GTF2H5, which is localized at the 6q24.2-26 deletion previously reported by our group to predict longer survival of high-grade serous ovarian cancer patients. Methods: In order to test if protein levels of GTF2H5 are associated with patients' outcome, we performed GTF2H5 immunohistochemical staining in 139 high-grade serous ovarian carcinomas included in tissue microarrays. Upon stratification of cases into high- and low- GTF2H5 staining categories (> and ≤ median staining, respectively) Kaplan-Meier and logrank test were used to estimate patients’ survival and assess statistical differences. We also evaluated the association of GTF2H5 with survival at the transcriptional level by using the on-line Kaplan-Meier plotter tool, which includes gene expression and survival data of 855 high-grade serous ovarian cancer patients from 13 different datasets. Finally, we determined whether stable short hairpin RNA-mediated GTF2H5 downregulation modulates cisplatin sensitivity in the SKOV3 and COV504 cell lines by using cytotoxicity assays. Results: Low expression of GTF2H5 was associated with longer 5-year survival of patients at the protein (hazard ratio [HR], 0.52; 95% CI, 0.29 to 0.93; p=0.024) and transcriptional level (HR, 0.80; 95% CI, 0.65 to 0.97; p=0.023) in high-grade serous ovarian cancer patients. We confirmed the association with 5-year overall survival (HR, 0.55; 95% CI, 0.38 to 0.78; p=0.0007) and also found an association with progression-free survival (HR, 0.72; 95% CI, 0.54 to 0.96; p=0.026) in a homogenous group of 388 high-stage (stages III-IV using the International Federation of Gynecology and Obstetrics staging system), optimally debulked high-grade serous ovarian cancer patients. GTF2H5- silencing induced a decrease of the half maximal inhibitory concentration upon cisplatin treatment in GTF2H5-silenced ovarian cancer cells. Conclusion: Low levels of GTF2H5 are associated with enhanced prognosis in high-grade serous ovarian cancer patients and may contribute to cisplatin sensitization.

        Awake craniotomy removal of a corticospinal tract developmental venous anomaly hemorrhage: A case report

        Ignacio J. Barrenechea,Luis M. Márquez,Vanina A. Cortadi,Héctor P. Rojas,Robin Ingledew 대한뇌혈관외과학회 2023 Journal of Cerebrovascular and Endovascular Neuros Vol.25 No.3

        Developmental venous anomalies (DVAs) are composed of mature venous vessels that lack malformed or neoplastic elements. Although the hemorrhage risk is considered negligible, some patients may have neurological symptoms attributable to acute infarction or intracranial hemorrhage secondary to thrombosis, in the absence of a coexisting cavernous malformation. We report the case of a 42-year-old patient who presented with acute left-hand paresis secondary to a subcortical hemorrhage. This bleeding originated from a DVA in the corticospinal tract area and was surgically drained through an awake craniotomy. To accomplish this, we used a trans-precentral sulcus approach. After the complete removal of the coagulum, small venous channels appeared, which were coagulated. No associated cavernoma was found. Although the main DVA trunk was left patent, no signs of ischemia or venous infarction were observed after coagulating the small venous channels found inside the hematoma cavity. Two weeks after the procedure, the patient’s hand function improved, and he was able to resume desktop work. DVA-associated hemorrhage within the cortico-spinal tract could be safely removed with modern awake mapping techniques. This technique allowed the patient to rapidly improve his hand function.

        Interaction between non-ionic surfactants and silica micro/ nanoparticles. Influence on the cleaning of dried starch on steel surfaces

        Encarnación Jurado,Otilia Herrera-Márquez,Antonio Plaza-Quevedo,José M. Vicaria 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.21 No.1

        This work analyses the cleaning of starch retained on stainless-steel fibres using the experimental BSFdevice that simulates the behaviour of a CIP washing system. In the formulations used for the cleaning,silica microparticles are included and the effectiveness of the cleaning is assessed by analysing differentvariables: pH, flow rate, concentration of microparticles, and different surfactants (alkylpolyglucosidesand ethoxylated fatty alcohols). When silica particles were added to the cleaning solutions of non-ionicsurfactants, the detersive capacity of the surfactants was affected. This effect appears to be due to theinteractions between the silica particles and the surfactants used.

        Bioelectronics-on-a-chip for cardio myoblast proliferation enhancement using electric field stimulation

        Ángel Aragón,María Cebro-Márquez,Eliseo Perez,Antonio Pazos,Ricardo Lage,José Ramón González-Juanatey,Isabel Moscoso,Carmen Bao-Varela,Daniel Nieto 한국생체재료학회 2020 생체재료학회지 Vol.24 No.3

        Background: Cardio myoblast generation from conventional approaches is laborious and time-consuming. We present a bioelectronics on-a-chip for stimulating cells cardio myoblast proliferation during culture. Method: The bioelectronics chip fabrication methodology involves two different process. In the first step, an aluminum layer of 200 nm is deposited over a soda-lime glass substrate using physical vapor deposition and selectively removed using a Q-switched Nd:YVO4 laser to create the electric tracks. To perform the experiments, we developed a biochip composed of a cell culture chamber fabricated with polydimethylsiloxane (PDMS) with a glass coverslip or a cell culture dish placed over the electric circuit tracks. By using such a glass cover slip or cell culture dish we avoid any toxic reactions caused by electrodes in the culture or may be degraded by electrochemical reactions with the cell medium, which is crucial to determine the effective cell-device coupling. Results: The chip was used to study the effect of electric field stimulation of Rat ventricular cardiomyoblasts cells (H9c2). Results shows a remarkable increase in the number of H9c2 cells for the stimulated samples, where after 72 h the cell density double the cell density of control samples. Conclusions: Cell proliferation of Rat ventricular cardiomyoblasts cells (H9c2) using the bioelectronics-on-a-chip was enhanced upon the electrical stimulation. The dependence on the geometrical characteristics of the electric circuit on the peak value and homogeneity of the electric field generated are analyzed and proper parameters to ensure a homogeneous electric field at the cell culture chamber are obtained. It can also be observed a high dependence of the electric field on the geometry of the electrostimulator circuit tracks and envisage the potential applications on electrophysiology studies, monitoring and modulate cellular behavior through the application of electric fields.

        Fragility Assessment of Bridges Considering Cumulative Damage Caused by Seismic Loading

        Dante Tolentino,Sergio Márquez-Domínguez,J. Ramon Gaxiola-Camacho 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.2

        In this paper, an approach is proposed to obtain fragility curves of reinforced concrete structures which can accumulate damage due to inelastic behavior when they are exposed to seismic load sequences in a given instant of time. The cumulative damage caused by earthquakes is quantified considering the maximum drift. This study is mainly focused on the stochastic uncertainty and variability of seismic occurrence, which are considered the main sources that can influence the performance of the structural system. The approach is validated with the help of a numerical study using a reinforced concrete continuous bridge considering the effect of cumulative damage given by seismic sequences for different time instants of 0, 50, 100, 150 and 200 years, after bridge construction. The bridge is located in the transition part of the soil in Mexico City. Different drift thresholds are studied to evaluate the probability of being exceeded. The proposed approach demonstrates the importance of considering the effect of cumulative damage under seismic sequences. In addition, it is assumed that it could be possible to design bridge structures that develop a certain pre-established drift threshold.

        Physical Inactivity, Sedentary Behavior and Chronic Diseases

        Karimé González,Jorge Fuentes,José Luis Márquez 대한가정의학회 2017 Korean Journal of Family Medicine Vol.38 No.3

        New research into physical activity suggests that it is no longer sufficient just to meet minimum levels recommend-ed by health guidelines in order to reduce cardiovascular risk. Both physical inactivity and sedentary behavior have their own health hazards and need to be addressed separately, in order to explore their different deleterious mech-anisms. The aim of this review was to define and to characterize both concepts, and their relationship with major non-communicable chronic diseases. A PubMed database search was undertaken, using the following key words: physical activity, physical inactivity, sedentarism, sedentary behavior, and non-communicable chronic disease. This literature review provides an updated view on physical inactivity and sedentary behavior, and reevaluates their prevalence and association with major non-communicable chronic disease.

        Master-Slave Teleoperation of Underactuated Mechanical Systems with Communication Delays

        Ollin Peñaloza-Mejía,Luis A. Márquez-Martínez,Jaime Alvarez-Gallegos,Joaquín Alvarez 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.2

        This paper addresses the control problem of master-slave teleoperation of a class of underactuated mechanicalsystems with communication delays. The core of the proposed solution introduces a suitable couplingmatrix, so the complete error dynamics is written in a linear part, and a nonlinear one, for which the matchingcondition is satisfied. Then, from this representation, discontinuous causal controllers are designed to achieve bilateralcoordination in force and position. The proposal is valid for underactuated manipulators with second-ordernon-holonomic constraints, and represents, to our best knowledge, a contribution in teleoperation systems wherethese mechanisms have been barely considered. Numerical simulations and real-time experiments developed overthe Internet are provided to show the effectiveness of the proposed control scheme.
