Título: Improving Simulation Accuracy of Printed Antennas via Frequency-Dependent Permittivity Adjustment Autor(es): Campitelli, Emiliano Nehuen; Fuentes, Indra; Areta, Javier Alberto; Gómez Berisso, Mariano Abstract: Significant discrepancies between the simulated and measured resonant frequencies in printed antennas often originate from over-simplified dielectric modeling. We present a validation strategy based on the frequency-dependent adjustment of the real part of the relative permittivity εr(f), motivated by the discrepancies between the simulated and measured return loss. We present V.N.A measurements for the return loss of micro-strip patch antennas printed on PCB and explain some details of the finite element simulations. The commercial platform employed, the materials and the boundary conditions, particularly, the implementation of a frequency-dependent permittivity function. We discuss the implications and validity of the present approach and finally show the agreement between the predicted and measured return loss in a broad frequency range. Based on the comparison between the experiment and the simulations, we discuss the limitations of the present approach and the perspective of continuation

Título: Decisiones metodológicas para el estudio de la escritura colaborativa en el ingreso universitario: un abordaje etnográfico. Autor(es): Orellana, Mauro; Rodríguez, Claudia del Valle; Reinaldi, Agostina; Dahbar, Juan Ignacio; Eisner, Laura Abstract: The aim of this paper is to present the research decisions involved in an ongoing ethnographic study of students’ collaborative writing practices within a three-week entrance course at the Social Communication Faculty (Universidad Nacional de Córdoba, Argentina). The research strategy was designed to meet the dynamics of an intensive course to produce different types of data through a variety of instruments. In this article, we focus on three key instances of data collection (which are connected to three moments of the course): a student survey delivered at the start of the course; observation of digital literacy events during a class activity to become familiar with Google Docs as a writing platform; and talk-around-screen interviews once students had turned in their final collaborative writing task (i.e. a reading report). We describe the research choices that we made throughout the fieldwork period, present some preliminary results and outline some conclusions about the potential of the approach adopted for the study. We conclude that interweaving these different types of data sources yielded a broader and more complex view of the writing practices carried out by students during their first contact with academic literacies in higher education.

Título: Del déficit al contacto. Perspectivas sociolingüísticas sobre las literacidades en las aulas Autor(es): Eisner, Laura Abstract: This reflection article recovers the theoretical-methodological decisions taken in an ethnographic study of reading and writing practices in a secondary school for adults, with the aim of generating alternative approaches to the “deficit perspective”. Based on the contributions of the New Literacy Studies and the sociolinguistics of writing, two central approaches are developed: the first is to think of the classroom as a contact zone, in which subjects with different literacy trajectories and positions regarding the school assessment regime converge; this allows us to understand with greater precision the mismatches that arise in relation to school tasks and to capture the alternative resolutions that students produce, overcoming a standard/deviation view. The second shift consists of analyzing the students’ productions, not only as finished texts, but in terms of the use of their communicative resources, highlighting their capacity for agency in mobilizing these resources based on their own criteria of adequacy. Finally, the possible contributions of this approach to the design of transformative pedagogical proposals are considered, which conceive classrooms as rehearsal spaces in which students can explore new possible voices.

Título: Modernización Digital en la Defensoría del Pueblo de Río Negro: Implementación de Haberes Digitales en el Marco del Plan Estratégico 2023-2027 Autor(es): Cambarieri, Mauro Germán; Amico, Bruno Gabriel; Santagati, Adriana Abstract: In a growing context of digital modernization, the public sector seeks to adopt digital technologies to improve the efficiency, transparency, and accessibility of its services. In 2018, through Decree No. 19/18 (Province of Río Negro, 2018), the Province of Río Negro adhered to the Federal Commitment for the Modernization of the State (Government of Argentina, 2017) and approved its Provincial State Modernization Plan (Province of Río Negro, 2018). In accordance with these commitments, the Ombudsman's Office of Río Negro (DPRN), with the support of the Secretariat of Special Programs and Liaison with the Federal Investment Council (CFI) of the Province of Río Negro and the CFI, formulated its first Institutional Strategic Plan (PEI) (Ombudsman's Office of Río Negro, 2023). This proposes a new organizational model aimed at improving the performance, quality, and public value of the services provided, through process reengineering, the incorporation of information and communication technologies (ICTs), and results-oriented management. That same year, the DPRN initiated an internal digital transformation process as part of its institutional modernization program, defined in guideline number two (2) of its Institutional Strategic Plan (PEI). This paper presents the proposed technology and architecture for digital asset management, outlining concepts, technical application details, and explaining the context for its use, as well as associated benefits and necessary technical resources.

Título: Microcredentials in the Bachelor's Degree in Systems, a degree regulated by the State and the Role of the W3C standard in the development of Verifiable Credentials Autor(es): Cambarieri, Mauro Germán; Viadana, Claudia Alejandra Abstract: The UNRN Bachelor's Degree in Systems is promoting a project to implement a microcredential system that allows for the digital and verifiable certification of specific skills acquired during training. This initiative responds to labor market demands and aligns with the requirements established by the Ministry of Education, according to Higher Education Law No. 24,521 and Resolution 1558/2021, which define accreditation standards, core content, and graduate profiles based on specific competencies. Microcredentials offer timely and agile certification of these capabilities, providing value to students and graduates before employers and institutions. The project is structured into two components: an Organizational-Regulatory component, which establishes the conditions for approval and operation of the system, and a Technological component, which contemplates the use of Verifiable Credentials (VC) proposed by the W3C. This technology guarantees authenticity, integrity, and portability through cryptographic mechanisms, eliminating intermediaries in validation. In addition, it is proposed to join the MIT Digital Credentials Consortium, which will allow UNRN to join an international network, access best practices and contribute to the development of open standards, positioning the initiative with global projection

Título: Análisis del discurso académico de la Antropología Social Autor(es): Wielfling, Fernanda Abstract: Within the disciplinary community of social anthropology, ethnography is understood as an approach, a method, and a text (Guber, 2001). The ethnographies, the object of this research, represent the textualization resulting from fieldwork (Marcus & Cushman, 1982). This article presents an analysis of ethnographies published in specialized Argentine journals, from the perspective of the complex genre or macrogenre (Martin, 1992). To this end, Systemic Functional Linguistics (SFL) provides the theoretical framework for the analysis of academic discourse, in particular the stratified concept of genre, register, and language (Eggins & Martin, 2003). Under the category of complex genre or macrogenre, ethnography integrates basic genres such as narrative, descriptive, and argumentative through ideational strategies of projection and expansion (extension, elaboration, and amplification). Furthermore, to address the study of these extensive texts, the concepts of macrotheme and macrorheme allow us to understand the structure and the particular rhetorical-functional framework in which macrorhetorical movements can be identified (Hasan and Reza, 2004). This work aims to contribute to the understanding of specific discursive practices within the disciplinary field of anthropology and, complementarily, to evaluate the usefulness of LSF's theoretical tools for the analysis of academic discourse.

Título: Multiliteracidad: La relevancia de tareas multimodales procesuales para la enseñanza de una Lengua Segunda en entornos universitarios Autor(es): Montemayor Borsinger, Ann; Coria, Ana María; Porto, Melina Abstract: This paper analyzes, from a multiliteracies perspective, the relevance of processual multimodal perspectives for L2 tasks in university settings, given their potential to refine the use of qualitative assessments. In particular, it examines a task based on maus, a graphic novel about the Holocaust by American cartoonist Art Spiegelman, which includes the two central semiotic modes of image and language. The theoretical framework is based on Meyer et al.’s multiliteracies model, which considers the integration of content and language to be fundamental to learning. Students were asked to design an alternative book cover for Maus and write about it. While the literature has emphasized the possibilities and limitations of each mode, here we focus on the interdependent nature of these modal sets, considered as task-relevant products of a broader learning process that takes into account different embodiments of meaning-making. Three samples were selected from a corpus composed of 46 alternative covers of the graphic novel and their descriptive texts. The selection was based on a qualitative evaluation in the tradition of Systemic Functional Linguistics, considering the notion of more effective and less effective choices that realize meaning depending on the context. We first describe the multimodal process-based task that takes into account multiliteracies and their contexts of use, and then we discuss the qualitative evaluation processes, taking into account the notion of a modal set. Based on the contrastive analysis of the most effective and least effective covers with their corresponding texts, we illustrate the potential of this type of task for qualitative process-based assessment and its implications for language teaching at the university level.

Título: La mirada del arte o el arte del descubrir. Apuntes situados en torno a la construcción de paisajes Autor(es): Melendo, María José Abstract: This article examines the representation of nature in art through an exploration of various perspectives on the landscape as a concept linked to the human gaze upon a territory. The objective is to develop a specific and situated approach; therefore, a defined corpus of analysis will be addressed. The discussion of the work of Patagonian artist Lorraine Green will serve to illustrate the capacity of art to construct landscapes. In this regard, by revisiting the heuristic processes involved in the creation of such landscapes, it becomes possible to appreciate the power of artistic perception in that act of “making visible,” a notion that in this paper is invoked while acknowledging its polysemic implications. Keywords: Contemporary Art, Landscape, Patagonia, Drawing, Philosophy

Título: La curaduría como metodología de investigación Autor(es): Melendo, María José; Cabrera, Gustavo Javier; Belenguer, María Celeste; Bohlmann, Tamara Ivana Elizabeth Abstract: This article examines the heuristic potential of curatorship as a research process through a retrospective analysis of the exhibition The Construction of the Desert. 1878-2021, designed by the Plataforma Horizontal collective, of which we are part (UNRN). Displayed in 2021 at the “Juan Sánchez” Municipal Museum of Fine Arts in General Roca/Fiske Menuco, the exhibition brought together diverse visual materials —artworks, documentary and photographic records— to challenge the narratives of the “Conquest of the Desert”, the 19th- century military occupation of Patagonia that annexed Indigenous territories to the Argentine National State. We propose categorizing the exhibition as site-specific curatorship, as it engages with the sociopolitical tensions of the local context. By revisiting official narratives, we highlight the power of montage as a tool for crafting alternative narratives that amplify dissident voices and memories silenced by History.

Título: Jaquear el archivo. Reflexiones a propósito del proyecto Inakayal vuelve. Bordar el genocidio mapuche Autor(es): Melendo, María José; Cabrera, Gustavo Javier Abstract: Over the past few decades, contemporary art has shown a growing tendency to use archival material as a source for the production of aesthetic experiences -a phenomenon that is expressed through a plurality of poetic operations that explore modes of appropriation and re-signification of documents from diverse origins. Considering this phenomenon, this article examines the dynamics at play in Inakayal Vuelve. Bordar el genocidio Mapuche (“Inakayal Returns. Embroidering the Mapuche Genocide”), an artistic project by Argentine artist Sebastián Hacher that resignifies a corpus of photographs belonging to the photographic archive of the Museum of Natural Sciences of La Plata, taken in the 19th century within the context of the military campaign over the Patagonian territory known as the “Conquest of the Desert.” We propose that, through specific dynamics characteristic of contemporary art, Hacher reclaims these photographs not only to observe their visible aspect -that consolidated by the official narrative- but also to probe the traces of what has been silenced: the spectral records of the hidden side of the National State’s so-called civilizing enterprise, thereby bringing latent pasts to the surface.

Título: Nuevos aportes al conocimiento del ensamble de peces del estuario del Río Negro, provincia de Río Negro, Argentina. Autor(es): Ulloa, Victor Andrés; Tombari, Andrea Diana; Funes, Aimé Itatí Abstract: This study documents the presence of juveniles of Ramnogaster arcuata, Brevoortia aurea, and Patagonotothen sima in the Negro River estuary, Argentina. Specimens were collected in February 2022 using trawl nets. The detection of these early ontogenetic stages provides evidence of the use of the Negro River estuary as a site for reproduction and early development, contributing to the ichthyological knowledge of northern Patagonia.

Título: Dados de Emociones. El juego como una experiencia extensionista Autor(es): Savarese, Mariana Abstract: This article addresses the experiences of the outreach team with the outreach project La palabra también Golpea#PongámoslePunto, of the Universidad Nacional de Río Negro in connection with the Zonal Hospital Dr. Ramón Carrillo. The objective is to raise awareness about the effects that daily violence has on the health of the community. Based on the outreach experience in secondary schools, the project proposed to raise awareness in primary schools in Bariloche. It was shown that school is a key resource to positively influence the violent behavior of students, since it acts in the affective management of children and, in addition, in their families. Since emotional education prevents violence, the outreach team developed Dados de Emociones, a game whose main objective is to help children express their emotions and make situations of violence visible. The Convention on the Rights of the Child considers play as a child’s essential right, being a fundamental need for their physical, social and emotional development. Play allows children to work on their emotions by relating to them and, in turn, to their environment. Dados de Emociones is a transversal project that links health centers, children with their families, the educational community and the university, from the perspective of critical outreach. This work presents the experiences gained through Dados de Emociones.

Título: Yama, una danza de ángeles Autor(es): Guzmán, Rubén Héctor Abstract: This text presents an evaluative analysis of Yama, considered one of the most significant works in the filmography of Alberto Honik. The author highlights the work's visionary nature, placing it even beyond the aesthetic standards of experimental cinema of its time, both Argentine and international. Honik, who worked as a physician, links his life experience to the creation of the film: the images he recorded emerged so forcefully from his surroundings that he could not separate his hand from the camera. This union is interpreted in McLuhan's terms as a prosthesis of the gaze, but what emerges from it is not merely a technical extension, but rather images that become organs of perception, possessing an unheard-of nakedness and an almost sacred harmony. A parallel is drawn with representatives of Absolute Cinema (such as Ruttmann, Eggeling, and Fischinger), as Honik constructs a symphonic visual rhythm in a silent film. Following Michel Chion's question about what we hear from what we see, the text suggests that the images—torn from the flow of life—evoke sounds and music through their rhythmic and precise succession. Finally, the text underscores the uniqueness of Honik's gaze, comparing it to that of a Tuareg: its beauty lies not in an art conscious of itself, but in the ability to bear witness to a nature that finds, almost by chance, a gaze worthy of it. Descripción: El artículo "Yama, una danza de ángeles", de mi autoría, se presentará en el 10º Simposio LabTIS, Artes en Relación, UNRN (noviembre de 2026), se publicará en la revista Hyperborea del LabTIS y estará disponible en el RID UNRN.

Título: Manejo eficiente del riego en maíz con información satelital Autor(es): Martínez, Roberto Simón; Reinoso, Lucio Gabriel; Roman, Jose Luis; Neffen, Evelyn; Montenegro, Ayelen; Muzi, Enrique; D´Onofrio, Mariano; Zelmer, Hernán; Cerrota, Alfonso Abstract: Within the Río Negro Basin in Argentina, the area cultivated with maize is approximately 25,000 hectares, with a production of 275,000 tons. Although this represents less than 1% participation at the national level, it is a region where the cultivated area is continuously increasing and constitutes a strategic option as an input for meat production in Argentine Patagonia. The average yield is around 11,000 kg/ha. As with all crops in this region, maize production requires irrigation to achieve yields (production is null without irrigation). Considering the growing decrease in water availability for irrigation in the region, it is necessary to implement actions aimed at improving the efficiency of water resource use, focusing on maximizing water productivity. In this regard, standardizing the calculation of maize crop irrigation requirements will help increase the efficiency in the use of productive inputs such as water and fertilizers.In this study, the FAO 56 methodology is applied with the support of satellite information in order to validate its use in maize cultivation.

Título: Adquisición de habilidades de comunicación mediante simulación clínica: Aspectos destacados por estudiantes de medicina Autor(es): Guaresti, Germán; Letón, Gabriela; Veneziale, Juan Lautaro; Bellotti, Mariela Ines Abstract: Learning communication skills is central in medical education. Clinical simulation provides conditions to foster comprehensive teaching and learning processes, although it is necessary to understand student acceptance as a way to evaluate and improve the strategy. The objective of this study was to analyze the perception of medical students after introducing clinical simulation sessions to optimize the teaching and learning processes of communication skills. The study design is observational, cross-sectional, mixed, and uses census sampling. A survey was conducted through a questionnaire, and a descriptive analysis of the results was performed. The results reveal a generally good perception, where the majority of students highlighted the debriefingspace or final reflection (64.8%), while 27.8% valued clinical simulation as a space for applying knowledge and more than 20% referred to the simulation scenario or the experience with a simulated patient. In conclusion, the most notable space was debriefing as an area for reflection and learning, although other appreciated aspects such as the application of knowledge or the use of a simulated patient are also important in understanding clinical simulation as a tool for learning communication skills

Título: Evaluación de la etapa virtual del curso de ingreso a la carrera de Medicina de la Universidad Nacional de Río Negro, Argentina Autor(es): Bellotti, Mariela Inés; Tognetti, Celia Abstract: Introduction. The entry course for Medical School at the Universidad Nacional de Río Negro-Sede Andina, Argentina, consists of three mandatory and selective phases. The implementation of the first of these phases, which is carried out online, was evaluated in this work. Subjects and methods. A cross-sectional descriptive study was conducted. Students’ perception of the virtual classroom was assessed through an online survey which covered aspects such as classroom content, teaching performance, synchronous virtual meetings and interaction between participants. Results. Most (95%) of the surveyed population was satisfied with the online phase of the entry course. The materials offered in the virtual classroom were considered adequate, as was the performance of the teaching team. Synchronous virtual meetings were considered useful, while the interaction between the students themselves was not considered as effective at this stage. Conclusions. Students had a positive perception regarding the online phase of admission, and areas for improvement were identified. This work provides evidence on the usefulness of virtual classrooms as support for the learning of university students.
