RESUMEN Introducción: La investigación psicológica puede ser desarrollada por investigadores y también por estudiantes de pregrado o posgrado. En un nivel de pregrado, la investigación psicológica es especialmente desafiante debido a la capacidad limitada de los estudiantes para desarrollar problemas de investigación y enfoques metodológicos coherentes y lógicos. Objetivo: El objetivo de este estudio es identificar las principales tendencias de investigación en las tesis de grado en psicología de las universidades peruanas. Como objetivo específico, se distinguieron las tendencias de diseño de investigación cuantitativa y cualitativa. Metodología: Se realizó una revisión sistemática descriptiva y retrospectiva de tesis de investigación en psicología de estudiantes universitarios peruanos, iniciando el proceso de extracción de datos a partir de la base de datos RENATI para una fase inicial de selección. El análisis de datos se realizó en dos fases. Resultados: Primero se organizaron los datos en relación a su frecuencia de las categorías de sexo de los autores, las universidades se catalogaron como universidades 1, 2, 3, 4 y 5 según su ranking, las categorías de años de publicación, número de autores Se obtuvieron diseños, tipo de metodología y área de publicación. A partir de estas categorías se establecieron estadísticos descriptivos de frecuencia. En la siguiente fase, se utilizaron análisis textuales lexicométricos y estadísticos para identificar los temas de tendencia de investigación. Discusión: Los principales resultados muestran que diferentes temas se enmarcan predominantemente dentro de la línea de investigación de la psicología clínica y de la salud, principalmente los relacionados con los estilos de afrontamiento, el estrés psicológico y el bienestar.

ABSTRACT Introduction: Psychological research can be developed by researchers and also by undergraduate or postgraduate students. In an undergraduate level, psychological research is specially challenging due to the limited ability of students to develop coherent and logical research problems and methodological approaches. Objective: The objective of this study is to identify the main research trends in undergraduate psychological theses from Peruvian universities. As a specific objective, quantitative and qualitative research design trends were distinguished. Methods: A descriptive and retrospective systematic review of psychological research thesis of Peruvian undergraduate students was conducted, starting the data extraction process starting with RENATI database for an initial screening phase. Data analysis was conducted in two phases. Results: First, data was organized in relation to its frequency of the categories of authors' sex, the universities were catalogued as universities 1, 2, 3, 4 and 5 according to their ranking, the categories of years of publication, number of authors, designs, type of methodology, and area of publication were obtained. Descriptive frequency statistics were established based on these categories. In the next phase, lexicometric and statistical textual analysis were used to identify research trending topics. Discussion: The main results show that different topics are predominantly framed within the clinical and health psychology line of research, mainly those related to coping styles, psychological stress and wellbeing.

ABSTRACT Introduction: In Peru, a high proportion of fully immunized people against COVID-19 has been achieved, which has mitigated the severity of the disease. Thus, under the recommendation of experts, the Peruvian government issued Supreme Decree 118-2022-PCM, which indicated that the use of masks is optional in open and ventilated enclosed spaces as of October 1, 2022. Objective: The aim of the present study was to find out the reasons why people continued to wear masks even though it was not mandatory in outdoor environments. Methods: A total of 335 people participated, with an average age of 26.11 years (73.1% women). A data collection form was prepared where sociodemographic and health information was requested; in addition, the question "Why do you continue to wear mask despite it being optional in open and closed ventilated spaces?" was included. The data obtained from the last open question of the instrument was analyzed by means of a discursive textual analysis (DTA) and an exploratory analysis through IRAMUTEQ. Results: Results indicate that people continue to wear masks, despite the lifting of the restrictions, to avoid contagion of COVID-19 and other respiratory diseases. In addition, the prevention of possible infection and transmission of the virus also focused on the family and vulnerable people. Discussion: It is concluded that the practice of wearing masks may be influenced by individual perceptions of risk and interpretations of responsibility and solidarity towards others.

RESUMEN Introducción: En el Perú, se logró una alta proporción de personas completamente inmunizados contra COVID-19 que ha mitigado la severidad de la enfermedad. Es así que, bajo la recomendación de expertos el gobierno peruano emitió el Decreto Supremo 118-2022-PCM, donde se indicó que el uso de la mascarilla es opcional en espacios abiertos y espacios cerrados ventilados a partir del 1 de octubre del 2022. Objetivo: El presente estudio fue conocer las razones por las cuales las personas continuaron usando mascarilla a pesar de que no era obligatorio en ambientes exteriores. Metodología: Participaron un total de 335 personas con un promedio de edad de 26.11 años (73.1% mujeres). Se elaboró una ficha de recolección de datos donde se solicitó información sociodemográfica y de salud; además, se incluyó la pregunta "¿por qué sigue utilizando la mascarilla a pesar de que es opcional en espacios abiertos y cerrados ventilados?" Los datos obtenidos de la última pregunta abierta del instrumento se analizaron mediante un análisis textual discursivo (ATD) y un análisis exploratorio a través de IRAMUTEQ. Resultados: Los resultados indicaron que, las personas seguían utilizando mascarillas, a pesar de estar levantadas las restricciones, para evitar contagios de la COVID-19 y de otras enfermedades respiratorias. Además, esta prevención de una posible infección y transmisión del virus es enfocada también a la propia familia y personas vulnerables. Discusión: Se concluye que, la práctica de usar mascarillas puede estar influenciada por las percepciones individuales del riesgo y las interpretaciones de responsabilidad y solidaridad frente a los demás.

ABSTRACT Sorghum ( Sorghum bicolor L. Moench) is a crop of paramount importance for Brazil, used in human and animal food. Considering the reduced number of studies on the influence of using a densimetric table in seed processing and its respective reprocessing to the equipment, this study aimed to evaluate the physiological quality of processed sorghum seeds reprocessed in a densimetric table and stored for three months. The treatments consisted of four collection points in the terminal part of the densimetric table, representing the processing material: upper part (P1), upper middle part (P2), middle part (P3), and lower part (D). Subsequently, the samples that were reprocessed in the table came from P3 and were divided into the upper part, which was followed to bagging (P3R1), and the lower part (P3R2), which followed for disposal, totaling six treatments. Storage was performed in a refrigerated environment, using a completely randomized design, with the means being compared by Tukey’s test at 5%. We concluded that the reprocessing of sorghum seeds in the densimetric table can improve the physical quality of a lot due to its standardization at the end of the stages, contributing to the improvement of the physiological quality and use of the material that would be discarded. The equipment performance allows the removal of seed fractions with lower apparent specific mass and promotes positive stratifications in the physiological quality of sorghum seed lots.

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

Resumen Introducción y objetivo. Las fracturas del malar son las fracturas faciales más frecuentes después de las nasales y se asocian preferentemente a accidentes de tránsito. En nuestro medio no disponemos de trabajos que exploren las caracteriticas de esta condicion. Nuestro objetivo es caracterizar las condiciones asociadas a las fracturas malares en la ciudad de Cali, Colombia. Material y método. Estudio observacional descriptivo en pacientes que consultan en el Hospital Universitario del Valle y atendidos por Cirugía Plástica entre agosto de 2019 y marzo de 2020 con diagnóstico de fractura malar por escáner facial. Registramos las variables edad, sexo, origen, procedencia, escolaridad, ocupacion, estado civil, mecanismo de trauma, ciudad del trauma, clasificacion de fracturas del malar, lateralidad, fractura del arco cigomático y fracturas faciales asociadas. No incluimos análisis sobre el manejo de las fracturas. Resultados. Identificamos 25 fracturas malares en 24 pacientes. El 88% en mayores de 18 años; 83.3% varones; el grupo etáreo con más casos fue el de 21-30 años (25%). La causa más común fue el trauma contuso (50%), seguido por las caídas (21%) y accidentes de tránsito (21%). La fractura malar tipo 3 impactada según Knight y North fue la más común (36%). Conclusiones. Encontramos que, en nuestro estudio, el trauma contuso fue la causa más frecuente de fractura malar. Consideramos que la información obtenida puede ser util para que la autoridad local se plantee estrategias para reducir su incidencia. Al clasificar el patron de fractura no se encuentra un tipo único de fractura, sino de combinaciones, lo que nos lleva a pensar que se requiere una nueva clasificación.

Abstract Background and objective. Malar fractures have been described as the most frequent facial fractures after nasal ones. These are frequently associated with traffic accidents. In our environment we do not have studies that explore the characteristics of this condition. Our objective is to characterize the conditions associated with malar fractures in the city of Cali, Colombia. Methods. A descriptive observational study is carried out in patients who consult at the Hospital Universitario del Valle and are cared for by the Plastic Surgery Section between August 2019 and March 2020, with a diagnosis of malar fracture in the facial scan. The variables age, sex, origin, education, occupation, marital status, mechanism of trauma, city of trauma, classification of malar fractures, laterality, fracture of the zygomatic arch and associated facial fractures were recorded. Analysis of the management of fractures is not included. Results. We identified 25 malar fractures in 24 patients; 88% in people over 18 years old; 83.3% were men; the age group with the most cases were 21-30 years old (25%); the most common cause was blunt trauma (50%), followed by falls (21%) and traffic accidents (21%). Type 3 malar fracture impacted according to Knight and North was the most common (36%). Conclusions. Blunt trauma is the most frequent cause of malar fracture in our study. The information obtained can be useful for the local authority to consider strategies to reduce its incidence. When classifying the fracture pattern, a single type of fracture is often not found and, on the contrary, there were combinations which leads us to think that a new classification is required.

Resumen El uso de la punción-aspiración con aguja fina (PAAF) en el diagnóstico histológico de lesiones ocupantes de páncreas es una alternativa frente al uso de agujas tru-cut en la obtención de tejido para su análisis, con una incidencia más baja de complicaciones y una recuperación casi inmediata sin necesidad de internación. El objetivo fue valorar la efectividad diagnóstica de las PAAF de lesiones ocupantes pancreáticas guiadas por tomografía axial computada (TAC) por vía percutánea, y su tasa de complicaciones a corto plazo. Se analizaron de forma retrospectiva todas las PAAF realizadas mediante guía tomográfica por vía percutánea con control en tiempo real, entre abril 2010 y diciembre 2015. Todas las PAAF se realizaron en presencia de un patólogo que inmediatamente tiñó e informó como adecuado para el análisis. La confirmación diagnóstica se hizo con el análisis anatomopatológico diferido. De las 54 PAAF realizadas, el diagnóstico anatomopatológico informó positivo para células neoplásicas compatible con adenocarcinoma en 52 pacientes (96%) y en otros dos (4%) como negativo para células neoplásicas. La sensibilidad del método fue 94% y la especificidad del 100%. Se registraron 4 casos de morbilidad post punción (2 dolores epigástricos y 2 hematomas de pared abdominal). Las punciones percutáneas de lesiones ocupantes pancreáticas guiadas por TC pueden considerarse un buen método diagnóstico mini invasivo, seguro, con una morbilidad post punción baja. La presencia del patólogo en el procedimiento permitió el diagnóstico citológico inmediato.

Abstract Fine-needle aspiration (FNA) for the histological diagnosis of occupying lesions in the pancreas as opposed to tru-cut needle biopsy to obtain tissue for analysis has been associated with a lower incidence of post-procedure complications, with almost immediate recovery and no need for hospital stay. Nev ertheless, the question of the diagnostic effectiveness of percutaneous computed axial tomography (CT)-guided FNA in solid pancreatic lesions has been raised. The aim of this study was to confirm the diagnostic effectivity of percutaneous CT-guided FNA in pancreatic space-occupying lesions and to assess short-term complications. All percutaneous CT-guided FNA with real-time monitoring, performed between April 2010 and December 2015, were retrospectively analyzed. In all cases 21-gauge needles were used. All FNA were performed in the pres ence of a pathologist who immediately stained and reported as adequate for analysis in all cases. The diagnosis was confirmed by histopathological evaluation. Of 54 FNA performed, final histopathological evaluation revealed neoplastic cells compatible with adenocarcinoma in 52 patients (96%) and was negative for neoplastic cells in two patients (4%). The sensitivity was 94%, and the specificity 100%. Post-FNA morbidity was observed in four patients, consisting of epigastric pain in two and abdominal wall hematoma in two other patients. Percutaneous CT-guided FNA of pancreatic space-occupying lesions was found to be a good, minimally invasive and safe method with low morbidity. The presence of the pathologist in the procedure allowed for immediate cytological diagnosis.

RESUMEN Las infecciones crónicas posteriores a reparaciones de la pared abdominal pueden presentarse como colecciones que involucran a la malla y suelen obligar a su extracción, mientras que los pseudoquistes son colecciones estériles con una gruesa pared fibrótica que debe ser extirpada para lograr la curación. Presentamos una paciente de 75 años con antecedente de eventroplastia, que consultó por un tumor abdominal de 6 meses de evolución, con características imagenológicas de pseudoquiste parietal. Durante la operación se encontró una malla preperitoneal no integrada a los tejidos y rodeada de “biofilm” y líquido turbio. La prótesis se retiró fácilmente y la aponeurosis, muy engrosada, se cerró borde a borde. El posoperatorio transcurrió sin incidentes y el cultivo desarrolló estafilococo aureus sensible a trimetoprima-sufametoxazol. Seis meses después, la evolución fue favorable y sin signos de recidiva.

ABSTRACT Chronic infections after abdominal wall repairs may present as collections involving the mesh which usually require removing the mesh, while pseudocysts are sterile collections with a thick fibrotic wall that must be removed to achieve healing. We report the case of a 75-year-old female patient with a history incisional hernia repair who sought medical advice due to an abdominal tumor which appeared 6 months before consultation with imaging tests suggestive of an abdominal wall pseudocyst. Surgery revealed a preperitoneal mesh without tissue integration surrounded by biofilm and cloudy fluid. The mesh was easily removed and the edges of the thick aponeurosis were sutured. The postoperative period evolved uneventful and the fluid culture was positive for staphylococcus aureus sensitive to trimethoprim-sufamethoxazole. Six months later the patient evolved with favorable outcome without recurrence.

Resumen: El objetivo de este estudio es indagar las percepciones estudiantiles al participar de una experiencia de articulación curricular en tres cursos iniciales de ingeniería civil mecánica utilizando aprendizaje basado en proyecto. El proyecto consistió en el diseño y construcción de una armadura usando impresión 3D. Se identifican las oportunidades y tensiones al participar de la experiencia, y se proponen mejoras al diseño. Se recolectaron las percepciones y opiniones de 11 estudiantes de dos de los cursos intervenidos, en dos momentos del semestre, utilizando encuestas grupales e individuales. Se utilizó análisis de contenido para procesar la información recolectada. Los resultados son coherentes con la literatura en cuanto al incremento en la motivación, la significación de contenidos y la valoración de la experiencia. El mayor desafío identificado por los participantes fue el trabajo en equipo. Se concluye que para mejorar la experiencia de aprendizaje se propone aumentar las coevaluaciones y la capacitación específica del cuerpo docente.

Abstract: The objective of this study is to explore students´ perceptions of a project-based learning intervention of three first-year courses in a Chilean mechanical engineering program. The project consisted of designing and building a truss by using 3D printing. Students’ views regarding this learning experience are assessed to identify learning opportunities and challenges that may emerge while working on the project. Individual and group interviews and questionnaires were conducted twice per semester in two courses to gather the views of 11 students. Collected data was processed by content analysis. The results showed higher motivation and content significance and increased experience value. These results are in agreement with findings reported in the literature. Teamwork was the biggest challenge identified by the participants. It is concluded that the learning experience can be improved by including frequent co-evaluations throughout the experience and the training of instructors on collaborative work.

Abstract Filaria lorenzo n. sp. is described in the Lesser Grison, Galictis cuja from northern Patagonia, Argentina. The new species can be differentiated from the eight species of Filaria from the Old World by the shape of the sclerotized preesophageal ring. The four remaining species of the genus parasitize American Mephitidae and/or Mustelidae. Filaria carvalhoi from Brazil and F. texensis from USA lack a preesophageal ring, whereas F. taxideae from USA and F. conepati from Argentina share with our specimens a preesophageal ring mostly mushroom shaped. Our specimens differ from F. taxideae by lacking lateral alae, by a different ornamentation of the female tail and by the male lacking adcloacal papillae. The new species also differs from F. conepati by the shape of the preesophageal ring and by the shape of the eggs. The indirect examination of the types of F. conepati and F. carvalhoi, corroborated the existence of differences between these two species, allowing us to refute their synonymy, as proposed by some authors. Our results extend the taxonomy of Filaria to 13 species and comprise the first report of a filarioid nematode for an Argentinean mustelid, and the first report for Patagonia.

ABSTRACT This study is dedicated to the development of a methodology based on supervised machine learning for soybean classification and justified as technological innovation to predict whether soybean classification is in the standard or non-standard established by normative instruction No. 11/2007 of the Ministry of Agriculture, Livestock, and Food Supply (MAPA). This study aimed to develop a website using supervised machine learning to classify soybeans, providing an assertive decision-making process in real-time. A technological tool was created to assist the farmer and the storage unit in the classification of soybeans, considering the perceived reality and potential instruments consistent with the reality of the area. Therefore, a website in Python language was created using the Pandas, Pandas Profiling, Seaborn, Matplotlib, NumPy, Scikit-learn, PyCaret, and Streamlit libraries. In the end, the system could predict whether the soybean is in the standard or non-standard established by the soybean classification normative. In this sense, the results showed the robustness and precision of the proposed new methodology.

Hydrogen (H2) was one of the first molecules discovered by our society, being the most abundant element in the whole universe. Thus, H2 has gained a lot of attention throughout the years, and it has lots of applications in different areas, especially since it offers ways to decarbonize a lot of sectors, mainly the ones where it has been proved to be very difficult to meaningfully reduce those carbon emissions. Herein, the main aspects of the hydrogen economy and its main applications for energy, transportation and industries are described. These main areas outline how important is H2 for our society highlighting how H2 can make those well-known processes more sustainable and greener. By the end, a brief discussion on these applications with future perspectives is presented.

Abstract Blastocerus dichotomus is the largest deer in South America. We have used 25 microsatellite markers detected and genotyped by Next Generation Sequencing to estimate the genetic variability of B. dichotomus in Argentina, where most of its populations are threatened. Primer design was based on the sequence of a shallow partial genome (15,967,456 reads; 16.66% genome coverage, mean depth 1.64) of a single individual. From the thousands of microsatellite loci found, even under high stringency selection, we chose and tested a set of 80 markers on 30 DNA samples extracted from tissue and feces from three Argentinean populations. Heterozygosity levels were low across all loci in all populations (H=0.31 to 0.40). Amplicon sequencing is a fast, easy, and affordable technique that can be very useful for the characterization of microsatellite marker sets for the conservation genetics of non-model organisms. This work is also one of the first ones to use amplicon sequencing in non-invasive samples and represents an important development for the study of threatened species.
