ABSTRACT A young woman presented at our clinic with sudden visual loss in the right eye, recurrent vertigo, and right-sided tinnitus. We performed a complete ophthalmological evaluation. This revealed effects of the condition on the small arterioles of the peripheral retina. Susac syndrome is characterized by the clinical triad of retinal arteriolar occlusions, cochleovestibular manifestations, and encephalopathy (which can be identified by neuroimaging abnormalities). Early diagnosis and immunosuppressive therapy improved the patient's visual acuity and the remission of her other symptoms. Hemi-central retinal artery occlusion is an atypical neuro-ophthalmological finding in this disease. However, its identification as a sign of Susac syndrome may facilitate timely diagnosis and accurate treatment. eye vertigo rightsided sided tinnitus evaluation retina occlusions manifestations which abnormalities. abnormalities . abnormalities) patients patient s symptoms Hemicentral Hemi central neuroophthalmological neuro disease However treatment

Abstract This study handles the possibility of formulating artisanal paints for wall paintings whose pigments come from plants, considering the need for additives and techniques capable of guaranteeing a good performance for internal walls of buildings. The lack of recipes and publications on the proportion of each component to obtain a paint with good performance motivated the preparation of the present research, in which formulations were developed through experimental design of mixtures to obtain homogeneous suspensions that comply with the limits stipulated by NBR 15079-1:2021. The performance of the mixtures in the Abrasion Resistance Test was evaluated according to the variations in the proportions of the components of the mixtures, and the pH and viscosity variable. The results indicate that the highest levels of abrasion resistance were achieved by raising the levels of pigment and bactericide, while high pH indices showed high viscosity and good performance against abrasion resistance, and vice versa. Through this study, it is concluded that it is possible to elaborate paints with Curcuma Longa L. pigments and natural inputs with satisfactory performance for the application and elaboration of mural paintings on internal walls of buildings. plants buildings research 1507912021. 1507912021 15079 1 2021. 2021 15079-1:2021 variable bactericide versa L 150791202 1507 202 15079-1:202 15079120 150 20 15079-1:20 1507912 15 2 15079-1:2 150791 15079-1: 15079-1 15079-

Resumo Opresente estudo buscou formular tintas artesanais para pinturas de murais cujos pigmentos sejam oriundos de plantas, considerando a necessidade de aditivos e técnicas capazes de garantir um bom desempenho para paredes internas de edificações. A falta de receitas e publicações sobre a proporção de cada componente para a obtenção de uma tinta com bom desempenho motivou a elaboração da presente pesquisa, em que foram desenvolvidas formulações através de delineamento experimental de misturas para obter suspensões homogêneas que estejam em conformidade com os limites de desempenho definidos pela NBR 15079-1:2021. O desempenho das misturas frente ao ensaio de resistência à abrasão (RAU) foi avaliado de acordo com as variações das proporções dos componentes das misturas e as variáveis de pH e viscosidade. Os resultados indicam que os índices mais elevados de RAU foram alcançados ao elevar os níveis de pigmento e bactericida, ao passo que altos índices de pH apresentaram viscosidade elevada e bom desempenho frente à RAU, e vice-versa.

Abstract: This study addresses the application of the Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology in the analysis of dissolved gases in oil of power transformers, being this a critical component in electrical systems. The adoption of this six-phase structured method allowed a comprehensive evaluation of the condition of the transformer units of the Ecuadorian electrical system based on the analysis of investment and expansion data of the sector, as well as the study of 1 099 DGA (Dissolved Gas Analysis) profiles obtained from a population of 153 transformers located in the different regions of continental Ecuador. The findings described in this work have the potential to significantly improve investment and maintenance strategies and policies. In addition, the adoption of automation techniques in the DGA classification process is proposed, using supervised learning models to enhance the reliability and efficiency of the public energy service. The results suggest that this approach not only improves the diagnosis within the maintenance activities, but also provides a solid basis to draw a roadmap towards a predictive asset management, resulting in a substantial improvement of the reliability of the national power system.

ABSTRACT In this study, the particle sizes distribution model that best characterizes the granulometric composition of saprolite ores fed to the Cuban Caron process was determined. Three samples of soft and hard streamers from the Punta Gorda, Camarioca Este and Yagrumaje Sur deposits were evaluated. The main mineralogical phases of the samples were identified by the X-ray powder diffraction method. The predominance of the mineralogical phases lizardite, clinochlore and chlorite-serpentine was observed in the different samples under study. The determination of the parameters of the granulometric models and the evaluation of the quality of their adjustment with statistical techniques, allowed us to identify that the Swebrec function is the one that best describes the distribution of the experimental particle sizes of the streamer samples, with determination coefficients higher than 0,91 and residual errors lower than 6,9 %.

RESUMEN En este estudio se determinó el modelo de distribución de tamaños de partícula que mejor caracteriza la composición granulométrica de las menas de saprolitas alimentadas al proceso Caron cubano. Se evaluaron tres muestras de serpentinas blandas y duras concernientes a los yacimientos de Punta Gorda, Camarioca Este y Yagrumaje Sur. Las principales fases mineralógicas de las muestras se identificaron por el método de difracción de rayos X en polvo. Se observó el predominio de las fases mineralógicas lizardita, clinocloro y clorita-serpentina en las diferentes muestras bajo estudio. La determinación de los parámetros de los modelos granulométricos y la evaluación de la calidad de su ajuste con técnicas estadísticas, permitió identificar que la función Swebrec es la que mejor describe la distribución de los tamaños de partículas experimentales de las muestras de serpentinas, con coeficientes de determinación superiores a 0,91 y errores residuales inferiores a 6,9 %.

HIV/AIDS remains one of the world's most significant public health and economic challenges, with approximately 36 million people currently living with the disease. Considerable progress has been made to reduce the impact of HIV/AIDS in the past years through successful multiple HIV/AIDS prevention and treatment interventions. However, barriers such as lack of engagement, limited availability of early HIV-infection detection tools, high rates of HIV/sexually transmitted infections (STIs), barriers to access antiretroviral therapy, lack of innovative resource optimisation and distribution strategies, and poor prevention services for vulnerable populations still exist and substantially affect the attainment of the UNAIDS 95-95-95 targets. A rapid review was conducted from 24 October 2022 to 5 November 2022. Literature searches were conducted in different prominent and reputable electronic database repositories including PubMed, Google Scholar, Science Direct, Scopus, Web of Science, IEEE Xplore, and Springer. The study used various search keywords to search for relevant publications. From a list of collected publications, researchers used inclusion and exclusion criteria to screen and select relevant papers for inclusion in this review. This study unpacks emerging opportunities that can be explored by applying machine learning techniques to further knowledge and understanding about HIV service design, prediction, implementation, and evaluation. Therefore, there is a need to explore innovative and more effective analytic strategies including machine learning approaches to understand and improve HIV service design, planning, implementation, and evaluation to strengthen HIV/AIDS prevention, treatment, and awareness strategies.

In the course of the past three decades, the concept of "plain language" has garnered increasing attention. Recent developments have further solidified this field, given the International Federation for Plain Language's definition of plain language, as well as the introduction of an ISO (International Organisation for Standardisation) Standard for plain language in 2023. These milestones suggest that plain language is set to play a more significant role in public communication. The International Federation for Plain Language defines plain language as communication in which the wording, structure, and design are so clear that the target audience can effortlessly find, understand, and use the information they need. However, this definition has faced criticism for its vagueness. In an effort to refine the definition, the ISO Plain Language Standard was introduced. It includes four governing principles: 1) Readers get the information they need; 2) Readers can easily find what they need; 3) Readers can easily understand what they find; and 4) Readers can easily use the information. Both the definitions of the ISO Standard and the International Federation for Plain Language concentrate on the understandability and usability of information in creating effective plain language documents. In this article, I argue that alongside understandability and usability, user experience should be considered as a third measurable element of success in plain language documents. Although existing research primarily focuses on usability and understanding, it gives limited attention to user experience, whereas I argue that user experience is a crucial factor in the creation of successful plain language documents. More specifically, I explore in this article the preference of respondents for plain language techniques used in documents in an attempt to establish a connection between the user's experience of these techniques and the document's usability and understandability. I also delve into users' overall experience with plain language documents and assess whether there is a correlation between overall experience and users' perceptions of specific plain language techniques. I further analyse users'experiences with plain language techniques within specific contexts, namely the medical, legal, and financial domains, to determine if the context influences their experience. In addition, I investigate the relationship between users'experiences with plain language techniques and extratextual factors, such as qualification, income, home language, the variety of Afrikaans they speak, and their level of engagement with the document's content. This comprehensive analysis aims to clarify the role of user experience in the success of plain language documents and it potentially prompts a reconsideration of experience, in addition to understandability and usability, when creating successful plain language documents. The study employed a quantitative correlational research design to examine the relationship between respondents' experience of plain language techniques, understandability and usability, extratextual factors, and the contexts in which these documents are encountered. Data collection involved a questionnaire-based survey, with 506 respondents participating through convenience sampling. The survey was conducted on the SUNSurvey platform at Stellenbosch University and was shared across social media platforms such as Facebook, Instagram, and WhatsApp to target individuals matching specific population characteristics. Respondents read one of 18 selected plain language documents and answered questions about the documents. Extratextual information, such as respondents' highest qualification level, annual income, home language, the variety of Afrikaans they speak, and the frequency with which they were exposed to the context, were collected. Engagement with the selected document was measured using Likert-scale statements. To assess understanding of the documents, factual questions were included, and usability questions were asked if respondents received one of the six forms that were tested. Experience with the plain language documents was also measured by means of Likert-scale statements. Importantly, respondents'experiences with specific plain language techniques were assessed, allowing them to express their experience with said techniques. The results of the study regarding respondents'experience of the plain language techniques used reveal overwhelmingly positive feedback. The Likert-scale ratings indicated that respondents across various demographic groups had favourable impressions of plain language techniques. This suggests that these techniques not only enhance document usability and understandability but are also well-received by users. The analysis of relationships between different variables yields intriguing findings. While many comparisons did not show statistically significant correlations, the noteworthy results are those that did. When examining respondents 'experiences with plain language techniques in documents across three contexts, no statistically significant relationship could be established, indicating positive experiences with these techniques across all contexts without contextual influence. In terms of understanding, most comparisons revealed a positive relationship between the experience of plain language techniques and understanding. This implies that respondents with more positive experiences better understood the documents, aligning with existing research and suggesting that improved understanding leads to more positive experiences. However, for usability there was no statistically significant relationship between the experience of plain language techniques and document usability, indicating that the study could not establish a clear link between these two factors. When considering extratextual factors, few statistically significant relationships were found. Only the respondents' home language showed a significant relationship with their experience of plain language techniques, suggesting that Afrikaans speakers had more positive experiences. For other extratextual factors, namely qualification, income level, and variety of Afrikaans, there were no significant correlations. In conclusion, this study highlights that positive experiences of plain language techniques are associated with better understandability, emphasising the importance of user experience in creating successful plain language documents. The results are positive for document designers, as diverse groups of people had positive experiences with these techniques, making plain language a tool for improving interactions with public documentation. This study suggests that considering user experience is crucial in defining plain language beyond just usability and understandability.

Die definisies van sowel die International Federation for Plain Language as die ISO Gewone Taal Standaard beklemtoon dat verstaanbaarheid en bruikbaarheid noodsaaklik is vir die skep van optimale gewonetaaldokumente. In hierdie studie voer ek egter aan dat daar 'n derde meetbare element van gewonetaaldokumente is wat 'n effek op die sukses daarvan het, naamlik die manier waarop die verbruiker die gewonetaaldokumente ervaar. Vir hierdie studie is ' n kwantitatiewe korrelasionele navorsingsontwerp gebruik om die verhouding tussen respondente se ervaring, verstaanbaarheid, en bruikbaarheid van gewone-taaldokumente, asook respondente se persoonlike eienskappe, en die kontekste waarin die gewonetaaldokumente voorkom, te bepaal. Opnamenavorsing met 'n vraelys as die data-insamelingsinstrument is uitgevoer en 506 respondente het aan die studie deelgeneem. Die resultate van die studie dui daarop dat respondente oor die algemeen positiewe ervarings met gewonetaaltegnieke in dokumente gehad het. Verder is 'n sterk positiewe verhouding tussen die ervaring en die verstaanbaarheid van die gewonetaaldokumente gevind. Dit dui aan dat 'n positiewe ervaring tot 'n beter begrip van die dokumente bydra. Dit is egter nie die geval met bruikbaarheid nie, aangesien geen statisties beduidende verhouding hier gevind is nie. Wat betref buitetekstuele faktore, het slegs huistaal 'n statisties beduidende invloed op die ervaring van gewonetaaltegnieke gehad. Die resultate van hierdie studie dui dus daarop dat ervaring 'n belangrike faktor is in die sukses van gewonetaaldokumente, en gevolglik oorweeg moet word om ervaring as een van die elemente in die definisie van gewone taal in te sluit.

RESUMEN Introducción: A lo largo de los años se ha propuesto una notable variedad de protocolos quirúrgicos periodontales, cuyo enfoque pasó de la simple resolución de defectos de tejidos blandos a la realización de procedimientos predecibles y mínimamente invasivos. Inicialmente se usaba el injerto gingival libre. Posteriormente se han probado diversas técnicas, incluidas aquellas con sustitutos de tejidos blandos, como membranas tipo Alloderm. Hoy en día se considera el gold standard el injerto de tejido conectivo subepitelial asociado al colgajo de avance coronal. Por último, se ha examinado la técnica Pinhole, con mayor preservación de tejido y resultado más estético. Objetivos: El objetivo de esta revisión fue la comparación de técnicas actualizadas para el tratamiento de recesiones múltiples en maxilar superior e inferior. El resultado del procedimiento se evaluó en términos de cobertura radicular completa, reducción de la recesión, ganancia en altura y volumen, resultado estético, dolor postoperatorio y morbilidad del lecho donante y receptor del paciente. Material y métodos: Se realizaron búsquedas electrónicas y manuales para recopilar estudios de boca dividida, ensayos clínicos controlados aleatorios, series de casos, estudios piloto, libros de periodoncia, estudios de casos, revisiones sistemáticas y metanálisis, incluyendo los defectos de recesiónes gingivales múltiples, en maxilar y mandibular, de las cuatro clases de Miller, debido a su extensa evidencia. Resultados: Se incluyeron treinta y cuatro publicaciones y se extrajeron datos sobre el resultado de las técnicas quirúrgicas de dieciocho artículos. La evaluación clínica analizó la cantidad de cobertura radicular completa, la reducción de la recesión y la ganancia de altura y volumen, mientras que la perspectiva del paciente se expresó en términos de satisfacción estética y posibles complicaciones postoperatorias. Los procedimientos de los últimos diez años mostraron mejores resultados en todos los factores mencionados anteriormente. Conclusión: La predictibilidad y la estabilidad del tratamiento a largo plazo representan los factores que guían el proceso de elección de la técnica y que añaden valor a los procedimientos más actualizados. Se observaron progresos tanto a nivel estético, al reducir las discrepancias entre el área intervenida y el tejido circundante, como a nivel postoperatorio, al aminorar las molestias del paciente. Los desafíos propios de esta rama pronto podrían encontrar respuesta gracias a su rápida evolución, la cual permite concebir más avances.

ABSTRACT Background: Along the years, a remarkable variety of periodontal surgical protocols has been proposed, the focus of which has shifted from the mere resolution of a soft tissue defect to the performance of predictable and minimally invasive procedures. Initially, the free gingival graft was used. Subsequently, many different techniques were experimented, including those using soft tissue substitutes, such as the Alloderm membrane. Nowadays, the association of the connective tissue graft with the coronally advanced flap is considered the gold standard. Finally, the Pinhole technique, being a more conservative method in terms of tissue preservation and aesthetic outcome, was proposed. Objectives: The aim of this review was the comparison of the updated techniques for the treatment of multiple periodontal recessions, affecting both maxilla and mandible. The procedure outcome was assessed in terms of complete root coverage, recession reduction, gain in height and volume, aesthetic outcome, patient’s post-operative pain and morbidity of donor and recipient sites. Material and methods: Electronic and hand searches were performed to collect split- mouth studies, randomized controlled clinical trials, case series, pilot studies, periodontal books, case studies, systematic reviews and meta-analysis, including maxillary and mandibular multiple gingival recession defects of all four Miller’s classes, for its extensive evidence. Results: Thirty-four publications were included and data regarding the surgical techniques outcome were extracted from eighteen articles. The clinical evaluation analyzed the amount of complete root coverage, recession reduction and gain in height and volume, while the patient’s perspective was expressed in terms of aesthetic satisfaction and possible postoperative complications. Procedures in the last ten years showed better results in all the above-mentioned factors. Conclusion: Procedural predictability and long-lasting treatment stability embody the factors driving the technique election process and adding value to more updated procedures. Progress was observed both at an aesthetic level, by reducing the discrepancias between the surgical region and the surrounding tissue, and at a postoperative level, by reducing patient discomfort. The challenges inherent to this branch could soon find answers thanks to its prompt evolution, which allows for further advances to be conceived.

Resumen Kombucha es una biopelícula compuesta por un cultivo simbiótico de bacterias y levaduras, conocido como SCOBY (Symbiotic Culture of Bacteria and Yeast). El SCOBY sufre procesos de deterioro y pérdida de atributos nutricionales, bioactivos y sensoriales, lo que impacta negativamente en su vida útil. Estas pérdidas pueden evitarse mediante métodos de secado, que ayudan a prolongar la vida útil y conservar los compuestos de acción de sus constituyentes. El objetivo de este estudio fue someter y evaluar Kombucha SCOBY a las técnicas de deshidratación por calor y liofilización. Los análisis incluyeron pH, sólidos solubles totales, acidez titulable total, turbidez, contenido de compuestos fenólicos totales, actividad antioxidante, evaluación microbiológica y pruebas de toxicidad in vivo. Todos los análisis fueron evaluados estadísticamente a un nivel de probabilidad del 5%, utilizando el software SAS. Tanto las bebidas de Kombucha como los productos secos exhibieron cantidades considerables de compuestos fenólicos y actividad antioxidante. Los recuentos de microorganismos oscilaron entre 104 y 108 CFU.ml-1 para bebidas y productos desarrollados. En las pruebas in vivo con Caenorhabditis elegans, no se observó un aumento en la mortalidad y los gusanos alimentados con los productos fermentados mostraron un mayor crecimiento. Por lo tanto, este estudio concluye que la producción de formas deshidratadas y liofilizadas de productos a base de Kombucha es un campo de investigación prometedor y ventajoso para la salud humana.

Abstract Kombucha is a biofilm composed of a symbiotic culture of bacteria and yeast, known as SCOBY (Symbiotic Culture of Bacteria and Yeast). The SCOBY undergoes deterioration processes and loss of nutritional, bioactive and sensory attributes, which negatively impacts its shelf life. These losses can be avoided by drying methods, which help to extend shelf life and preserve the action compounds of its constituents. The objective of this study was to subject and evaluate Kombucha SCOBY to drying techniques by heat dehydration and freeze-drying. Analyses included pH, total soluble solids, total titratable acidity, turbidity, total phenolic compound content, antioxidant activity, microbiological assessment, and toxicity in vivo testing. All analyses were statistically evaluated at a 5% probability level, using SAS software. Both Kombucha beverages and dry products exhibited considerable amounts of phenolic compounds and antioxidant activity. Microorganism counts ranged from 104 to 108 CFU.ml-1 for developed beverages and products. In In vivo tests with Caenorhabditis elegans, no increase in mortality was observed, and worms fed with the fermented products showed enhanced growth. Thus, this study concludes that producing dehydrated and freeze-dried forms of Kombucha-based products is a promising and advantageous field of researchfor human health.

ABSTRACT The wholesome and competent training of the teacher of English at the University of Pinar del Río "Hermanos Saiz Montes de Oca" presented limitations, as the contents of the Caribbean cultural identity were not worked on in a coherent and systemic way, so this article had as its objective to propose a set of strategic pedagogical-didactic actions to better the training process of the Caribbean cultural identity, in the teachers of English at the University of Pinar del Río "Hermanos Saíz Montes de Oca". The dialectical research paradigm was used and a set of methods at the theoretical level (analysis and synthesis and induction and deduction), at the empirical level (document analysis, interviews, and focus groups), as well as descriptive statistical techniques. A preliminary diagnosis of the initial state of the training of the Caribbean cultural identity of the teacher of English at the University of Pinar del Río was carried out. A theoretical-practical basis related to the training of the Caribbean cultural identity was presented that served to develop the set of six strategic pedagogical-didactic actions to better this process. The updating, redesign, methodological work, training, and evaluation actions were articulated in a coherent and systemic way and allow the training of the Caribbean cultural identity of the teacher of English at the above-mentioned University.

RESUMEN Introducción: A lo largo de los años se ha propuesto una notable variedad de protocolos quirúrgicos periodontales, cuyo enfoque pasó de la simple resolución de defectos de tejidos blandos a la realización de procedimientos predecibles y mínimamente invasivos. Inicialmente se usaba el injerto gingival libre. Posteriormente se han probado diversas técnicas, incluidas aquellas con sustitutos de tejidos blandos, como membranas tipo Alloderm. Hoy en día se considera el gold standard el injerto de tejido conectivo subepitelial asociado al colgajo de avance coronal. Por último, se ha examinado la técnica Pinhole, con mayor preservación de tejido y resultado más estético. Objetivos: El objetivo de esta revisión fue la comparación de técnicas actualizadas para el tratamiento de recesiones múltiples en maxilar superior e inferior. El resultado del procedimiento se evaluó en términos de cobertura radicular completa, reducción de la recesión, ganancia en altura y volumen, resultado estético, dolor postoperatorio y morbilidad del lecho donante y receptor del paciente. Material y métodos: Se realizaron búsquedas electrónicas y manuales para recopilar estudios de boca dividida, ensayos clínicos controlados aleatorios, series de casos, estudios piloto, libros de periodoncia, estudios de casos, revisiones sistemáticas y metanálisis, incluyendo los defectos de recesiónes gingivales múltiples, en maxilar y mandibular, de las cuatro clases de Miller, debido a su extensa evidencia. Resultados: Se incluyeron treinta y cuatro publicaciones y se extrajeron datos sobre el resultado de las técnicas quirúrgicas de dieciocho artículos. La evaluación clínica analizó la cantidad de cobertura radicular completa, la reducción de la recesión y la ganancia de altura y volumen, mientras que la perspectiva del paciente se expresó en términos de satisfacción estética y posibles complicaciones postoperatorias. Los procedimientos de los últimos diez años mostraron mejores resultados en todos los factores mencionados anteriormente. Conclusión: La predictibilidad y la estabilidad del tratamiento a largo plazo representan los factores que guían el proceso de elección de la técnica y que añaden valor a los procedimientos más actualizados. Se observaron progresos tanto a nivel estético, al reducir las discrepancias entre el área intervenida y el tejido circundante, como a nivel postoperatorio, al aminorar las molestias del paciente. Los desafíos propios de esta rama pronto podrían encontrar respuesta gracias a su rápida evolución, la cual permite concebir más avances.

ABSTRACT Background: Along the years, a remarkable variety of periodontal surgical protocols has been proposed, the focus of which has shifted from the mere resolution of a soft tissue defect to the performance of predictable and minimally invasive procedures. Initially, the free gingival graft was used. Subsequently, many different techniques were experimented, including those using soft tissue substitutes, such as the Alloderm membrane. Nowadays, the association of the connective tissue graft with the coronally advanced flap is considered the gold standard. Finally, the Pinhole technique, being a more conservative method in terms of tissue preservation and aesthetic outcome, was proposed. Objectives: The aim of this review was the comparison of the updated techniques for the treatment of multiple periodontal recessions, affecting both maxilla and mandible. The procedure outcome was assessed in terms of complete root coverage, recession reduction, gain in height and volume, aesthetic outcome, patient’s post-operative pain and morbidity of donor and recipient sites. Material and methods: Electronic and hand searches were performed to collect split- mouth studies, randomized controlled clinical trials, case series, pilot studies, periodontal books, case studies, systematic reviews and meta-analysis, including maxillary and mandibular multiple gingival recession defects of all four Miller’s classes, for its extensive evidence. Results: Thirty-four publications were included and data regarding the surgical techniques outcome were extracted from eighteen articles. The clinical evaluation analyzed the amount of complete root coverage, recession reduction and gain in height and volume, while the patient’s perspective was expressed in terms of aesthetic satisfaction and possible postoperative complications. Procedures in the last ten years showed better results in all the above-mentioned factors. Conclusion: Procedural predictability and long-lasting treatment stability embody the factors driving the technique election process and adding value to more updated procedures. Progress was observed both at an aesthetic level, by reducing the discrepancias between the surgical region and the surrounding tissue, and at a postoperative level, by reducing patient discomfort. The challenges inherent to this branch could soon find answers thanks to its prompt evolution, which allows for further advances to be conceived.

Resumo A gestão de conflitos surge como uma alternativa viável para abordar as causas subjacentes quando surgem diferenças entre os membros de uma organização. Este artigo tem como objetivo propor um modelo de conciliação para gerir as causas de conflito entre os alunos de espanhol como segunda língua e o pessoal docente costa-riquenho de uma agência estrangeira, responsável pela preparação de candidatos voluntários em aspectos culturais, linguísticos e técnicos para o seu futuro emprego. Baseia-se nos resultados de uma investigação anterior que identificou as causas do conflito em ambos os grupos. O modelo de conciliação com uma abordagem colaborativa foi escolhido, uma vez que procura satisfazer todas as partes envolvidas através de uma estratégia em que todos ganham. Como resultado, foi concebido um modelo de conciliação em três fases, que inclui várias actividades presenciais e virtuais adaptadas ao período de formação limitado de três meses oferecido pela agência.

Abstract Conflict management emerges as a viable alternative for addressing underlying causes when differences arise among members of an organization. This paper aims to propose a conciliation model to manage the causes of conflict between learners of spanish as a second language and costa rican teaching staff at a foreign agency, which is responsible for preparing volunteer candidates in cultural, linguistic, and technical aspects for their future job. It is based on the results of previous research that identified the causes of conflict in both groups. The conciliation model with a collaborative approach was chosen, as it seeks to satisfy all the parties involved through a win-win strategy. As a result, a three-stage conciliation model was designed, which includes various in-person and virtual activities tailored to the limited three-month training period offered by the agency. In addition, the model is supported by principles of strategic educational administration, including a cycle of transformation and continuous improvement that begins with the vision and mission of the entity and continues with stages of planning, organizing, evaluating, and providing feedback
