Aprendizaje Basado en el Lugar (ABL) y el aprovechamiento de la experiencia cotidiana: revisión de una propuesta didáctica de trabajo de campo para aprender Geografía
Authors: Retana Quirós Daniela
Published: June 2023

With the purpose of strengthening the development of geographic skills in students, the design and application of the strategy "Active Pause: Let's read the space!" follow the guide of the Place-Based Learning (PBL) theory. The strategy proposes to validate the relationships that the students have built with their immediate environment and transfer them to the academic learning scenario, thus recognizing an opportunity to evaluate the understanding of the curricular contents reviewed during the class and to position the students as agents of construction and transformation of their territoriality. The proposal identified a student role that make them active and necessary, and a teaching role of guidance and accompaniment, where formative evaluation takes special prominence in a scenario of undeniable curricular flexibility, understanding that spatial readings are made from the autonomy and immediate experience of the students.
Voces de poetas
Authors: Colonna Valentina
Published: June 2023

En este artículo se pretende desarrollar un primer estudio fonético aplicado a la lectura de poesía española. Tras una presentación teórica, se presenta un análisis experimental. Primeramente introducimos y analizamos cualitativamente tres poetas representativos del siglo XX hispanohablantes, a saber, Rafael Alberti, Jorge Guillén y Pablo Neruda, para ser posteriormente comparados con  tres poetas contemporáneos. Se emplea un enfoque fonético experimental y se utiliza la metodología del proyecto VIP-Voices of Italian Poets, destacando un sistema de norma y variación. Finalmente se confirma la importancia de los estudios experimentales para profundizar la vocalidad de la poesía. Además, la investigación, aunque basada en un pequeño corpus de grabaciones, permite comparar tres principales estilos diferentes de lectura de poesía, considerando una selección razonada de índices. Por último, gracias a un enfoque cualitativo-comparativo, es posible detectar no sólo divergencias estilísticas entre el siglo pasado y el actual, sino también diferentes formas de producir uno de los principales aspectos retóricos de la poesía, es decir, el encabalgamiento.

The districts of Fener and Hasköy, in the Golden Horn, were mostly populated by the descendents of the Jews of Hispanic origin, they became an important scenery to meet them.Keywords: Spain, Ottoman Empire, The Enlighment, Sephardi Jews, Travel Literature, diplomats, soldiers, Balat, Hasköy, Angel Pulido, Pin i Soler.
Targeted disruption of hydroxyl chemistry and crystallinity in natural fibers for the isolation of cellulose nano-fibers via enzymatic treatment
Authors: Janardhnan Sreekumar , Sain Mohini
Published: June 2023

Cellulose is the Earth’s most abundant biopolymer. Exploiting its environmentally friendly attributes such as biodegradability, renewability, and high specific strength properties are limited by our inability to isolate them from the secondary cell wall in an economical manner. Intermolecular and intramolecular hydrogen bonding between the cellulose chains is the major force one needs to overcome in order to isolate the cellulose chain in its microfibrillar form. This paper describes how a hydrogen bond-specific enzyme disrupts the crystallinity of the cellulose, bringing about internal defibrillation within the cell wall. Bleached kraft softwood pulp was treated with a fungus (OS1) isolated from elm tree infected with Dutch elm disease. FT-IR spectral analysis indicated a significant reduction in the density of intermolecular and intramolecular hydrogen bonding within the fiber. X-ray spectrometry indicated a reduction in the crystallinity. The isolated nano-cellulose fibers also exhibited better mechanical strength compared to those isolated through conventional methods. The structural disorder created in the crystalline region in the plant cell wall by hydrogen bond-specific enzymes is a key step forward in the isolation of cellulose at its microfibrillar level.

Authors: Bhat A. H. , Abdul Khalil H. P. S.
Published: June 2023

This study presents the utilization of oil palm ash (OPA), a siliceous material from the fiber of oil palm biomass, as a nanofiller for the development of polymer nanocomposites. Polypropylene-based polymer nano-composites reinforced with OPA along with a compatibilizer were prepared by a melt-mixing technique, using a double screw extruder. Variations in the mechanical, morphological, and thermal properties with the filler and compatibilizer loading were studied. The best dispersion occurred in the polymer nano-composites for which the interactions between the polymer matrix and nanosized OPA appeared to be the highest. The particle size and the dispersion of the oil palm ash within the matrix were determined by transmission electron microscopy. The as-synthesized composite materials were typically characterized by tensile and impact test methods. The morphology of the composite materials was studied by scanning electron microscopy. The thermal properties determined by thermogravimetric analysis (TGA) showed enhanced thermal stability of a series of composite materials. Also, melting studies were carried out by differential scanning calorimetry.

Authors: Li Jinhui , Osman Mojeeb AL-Rahman EL-Nor , Teng Zhidong
Published: June 2023

In this paper, a dynamical model of malaria transmission with vector-bias and timedependent controls is investigated. The controls include the RTS,S malaria vaccine, using insecticide-treated mosquito net, treatment of infectious human, and indoor spraying. For constant controls, the existence and stability of equilibrium, as well as the existence of backward bifurcation, are obtained. The sensitivity analysis quantifies the impact of parameters and controls on the basic reproduction number. For time-dependent controls, by using the Pontryagin’s maximum principle the existence and expression of optimal controls are established. As an application of the model and control strategies, the malaria transmission and controls in Democratic Republic of Congo are discussed. To be specific, we simulate the reported cases of Democratic Republic of Congo by World Health Organization and predict the trends. Cost-effectiveness analysis and numerical simulations show that combining all controls can minimize the number of infected humans to the full extent, using insecticide-treated mosquito net is the most cost-effectiveness strategy, combining RTS,S malaria vaccine with using insecticide-treated mosquito net and treatment of infectious human is also cost-effective among all the strategies with good effect.
Application of PAN/α-Fe2O3-Bentonite as A Photocatalytic Membrane for The Photodegradation of Methylene Blue
Authors: Sitompul Dina Wardani , Kemala Tetty , Darmawan Noviyan
Published: June 2023

The intricate molecular structure of the dyes in wastewater makes it difficult to biodegrade, which could harm the environment. Currently, semiconductor-based photocatalytic methods are being developed to remove dyes from water. In this study, the α-Fe2O3-bentonite photocatalyst was synthesized by mechanical milling and immobilized in polyacrylonitrile (PAN) membrane by phase inversion. Analysis of the composition and surface morphology of the synthesized samples was carried out by FTIR, XRD, and EDX. The performance of the photocatalytic membrane was studied by investigating the removal of methylene blue (MB). Photocatalytic membrane with 2% α-Fe2O3-bentonite had the best performance in removing MB (10 ppm) that reached 99.84% at pH 11.5 with an irradiation time of 300 minutes under direct sunlight. The reuse cycle of the photocatalytic membrane was also carried out and the results showed that there is no significant change in the photodegradation efficiency after 3 cycles. Photocatalyst immobilization on PAN membranes is proven to overcome the post-recovery problem of photocatalysts and making easier to reuse. The photocatalyst membrane synthesized in this study can be used as an alternative for removing dyes from water.
The Potential of Nanocellulose Acetate as Surfactant for Water-Vegetable Oil Systems
Authors: Ibrahim Ikhsan , Ledyastuti Mia
Published: June 2023

Indonesia, as an agricultural country, has a variety of abundant plants. Cellulose is a component in plants that can be modified to increase its economic value. Resizing cellulose to nanocellulose and modification of nanocellulose to nanocellulose acetate can increase its potential as a surfactant. Resizing cellulose can be done using the strong acid hydrolysis method. An acetic anhydride reagent was utilized to convert the surface hydroxyl functional group into acetyl. The successful production and modification of nanocellulose were confirmed using fourier transform infrared and particle size analysis characterization. The infrared absorption spectrum of cellulose and nanocellulose showed no difference in peaks. Particle size distribution showed that nanocellulose I (CNC I) and nanocellulose II (CNC II) has sizes of 142 nm and 319 nm, respectively. The property of nanocellulose molecules in an oil-water system was simulated using molecular dynamics with GROMACS 2020.6 software. Appropriate trends can be seen in the interfacial tension of water-vegetable oil systems. The value of interfacial tension decreases with the addition of nanocellulose acetate compared to the addition of nanocellulose. With the agreement between the experimental and computational results, nanocellulose acetate can act as a surfactant.

Published: June 2023

Cancer is defined as a disease caused by progressive and abnormal cell proliferation in the body. This condition is caused by deoxyribonucleic acid (DNA) changes, which causes cells to lose their normal function. The aim of this study is to find that flavonoid compounds have a more stable interaction than tamoxifen as anti-cancer candidates. Research has been conducted in silico with molecular docking (AutodockTools-1.5.7) and molecular dynamics of 200 flavonoid compounds. Furthermore, pharmacokinetic parameters, toxicity, and the application of the Lipinski Rule of Five were investigated. Based on molecular docking results, the compounds eriocotrin, glabrol, kaempferitrin, linarin, and narirutin have more stable interactions with lower binding energy (∆G) than tamoxifen. From the results of molecular docking, molecular dynamics, and pharmacokinetic studies, it is predicted that the kaempferitrin compound can be used as an anti-cancer candidate and does not cause toxicity through further research.

Authors: Trzensimiech Annika Christina
Published: June 2023

Die vorliegende Arbeit untersucht den Zusammenhang zwischen KI-gestützten Auswahlprozessen und der Geschlechterdiskriminierung. Die Personalbeschaffung deckt den Personalbedarf eines Unternehmens durch Sichtung von Bewerbungen und Identifizierung qualifizierter Bewerber*innen. Unternehmen nutzen KI-Systeme, um Gender Bias zu beseitigen, aber es besteht die Beobachtung, dass Frauen trotzdem aufgrund ihres Geschlechts benachteiligt werden können. Es wird daher der Frage nachgegangen, inwieweit Frauen aufgrund eines Bias von KI-gestützten Auswahlverfahren in Bewerbungsprozessen diskriminiert werden. Das Ziel dieser Hausarbeit ist es, den Forschungsstand und die Anwendungsbereiche von KI-gestützten Methoden in Bewerbungsprozessen von Unternehmen zu untersuchen und anschließend auf potenzielle Gender Bias zu analysieren.

Retos epistemológicos de la archivística en las entidades privadas en Colombia
Authors: Navarro Alvarado Paula Estefanía
Published: June 2023

Este ensayo nace a partir de la identificación de las necesidades documentales de las entidades privadas en Colombia, las cuales no deben responder ante el ente rector archivístico de acuerdo con la ley colombiana. Al respecto, se identifican los retos epistemológicos que enfrenta la archivística en las entidades privadas, así como los elementos que brindan cientificidad al área, y se destaca el rol del archivista frente al abordaje de desafíos y la resolución de problemas. Para ello, se adoptó la técnica de observación pasiva a un proyecto de gestión documental en una entidad privada, y se corroboraron los datos obtenidos mediante la investigación bibliográfica. Así, primero, se evidenció el panorama de la archivística en las entidades privadas; posteriormente, se identificaron y desarrollaron tres retos epistemológicos: la adaptación de instrumentos archivísticos, el cuestionamiento del concepto de documento, y el cuestionamiento del alcance de la archivística. Como resultado, la principal característica que brinda cientificidad y disminuye cuestionamientos es la resolución de problemas basada en los paradigmas y la teoría propia del área; también, la unanimidad en el gremio acerca de la aplicación y la adaptación de herramientas archivísticas para garantizar la satisfacción del usuario. Se concluye que la archivística posee los fundamentos teóricos y los paradigmas necesarios para afrontar los retos epistemológicos en el campo laboral; sin embargo, en Colombia, el enfoque del archivista debe ser el usuario, a fin de que la resolución de problemas sea efectiva y no se aplique la teoría archivística de modo impositivo y burocrático.

Objetivou-se analisar a relação entre o processo de ensino aprendizagem e a saúde mental de estudantes do ensino superior do estado do Ceará, Brasil, durante o isolamento social na pandemia Covid-19. Estudo exploratório, descritivo e transversal, realizado com 3.691 estudantes universitários no ano de 2020. Analisaram-se as variáveis preocupação com a continuidade do curso de forma presencial, condições de acesso à internet e satisfação em relação à participação nas atividades pedagógicas durante o isolamento. Verificaram-se relações positivas (r>0) e estatisticamente significativas (p<0,001) entre a Escala Global MHI-38, as dimensões Bem-estar positivo e Distresse, as dimensões primárias e melhores condições de acesso à internet e satisfação quanto às atividades pedagógicas da instituição. Em contrapartida, constataram-se relações negativas (r<0) e estatisticamente significativas (p<0,001) entre as dimensões mensuradas e a preocupação com a continuidade do curso de forma presencial. As dimensões primárias apresentaram tendência para aumentar com o aumento da satisfação em relação às atividades pedagógicas e das condições de acesso à internet. Por outro lado, as dimensões primárias diminuíram com o aumento da preocupação com a continuidade do curso de forma presencial. Os resultados sugerem que a mudança no modelo de ensino aprendizagem impactou de forma significativa a saúde mental dos estudantes e que melhores condições de acesso às atividades tendem a otimizar o quadro, enquanto o intenso cenário de preocupação torna o adoecimento psíquico mais expressivo. Logo, cabe às instituições a criação e o fortalecimento das políticas de assistência aos discentes no âmbito da saúde mental.

Authors: Suwahono Suwahono , Zulfirman R. Krisna Dara Alifa
Published: June 2023

Understanding the Nature of Science (NoS) could help improve thinking and reasoning skills. Students could use their critical thinking (CT) skills to help themselves in solving problems. Based on the NoS, this study sought to assess the CT skills of chemistry pre-service teachers at university. This study used a qualitative with a case study as the method. A purposive sampling technique was elaborated to select the research object. The respondents were chemistry students at university. The data sources were open-ended questions and interviews from the NoS questionnaire. The method of data triangulation was employed to conclude the study findings. The results showed that the CT skills possessed by chemistry pre-service teachers: were interpretation skills, inference skills, and self-regulation skills. Those skills were still in the low category. The participants also lacked in explaining, evaluating, and analyzing the students' abilities. Thus, the understanding of NoS informants can be categorized in the transitional cohort. The research findings became the department's input because some students still struggled to analyze NoS aspects in chemistry, especially through each stage of CT skills. Hence, future research is suggested to develop the students' CT skills in applying the NoS aspect in chemistry learning, especially for the pre-service teacher.

O título poético desse texto que é sem dúvida um texto feminista, toca em áreas inclusivas e comuns às relações humanas. Brota de um sentimento de que muitas coisas e crenças nas quais acreditávamos ontem, foram caindo nos tempos de hoje. Tiveram seus sentidos derrubados muito embora ainda os seguíssemos numa espécie de repetição naturalizada dos mesmos. A repetição naturalizada nos ilude, enfraquece, cansa e até impede a reflexão sobre a vida de hoje. Por isso, há que revisitar-nos, revisitar nossos sentidos e buscas.

Determine the optimal fixation position tendon graft on the posterior surface of the tibia subject to recovery of the hamstring muscle which ensuring the greatest stability of the lower leg during external rotation. Methods. Models of the knee joint were built with different  attachment points of the popliteal graft muscle in the ANSYS software environment. The criteria for evaluating the effectiveness of selecting the fixation point of the transplant were chosen as the degree of movement of the finite parts elements of the model. Results. The smallest movements in all directions received in the case when the transplant fixed as far as possible outwards and upwards, near the joint surface. Maximum — in the direction of the coordinate axes, as well as full movement were recorded for the control model, in the absence of the hamstring tendon The nature of the distribution of displacement fields in all models p graft and control were identical. Biggest there were additional displacements in the direction of the x axis (outward). on the front border of the platform, and the largest negative (so far redins) on the back. The largest additional shifts to the sides the y (front) axes are fixed at the leftmost limit and the largest negative (back) — to the rightю Conclusions. In view of the stability of the lower leg during rotational loading, the most effective is fixation of the hamstring graft on the back surface of the fibula is as late as possible and closer to its cardiac surface, finished in this case, the dimensions are found to be the smallest in all directions. The greatest displacement in all directions obtained in the control model for less tendon hamstring muscle.

Authors: Chernyshov Olexandr , Golbaum Maksym
Published: June 2023

Spondylolisthesis is a pathology of the musculoskeletal system that causes a vertebra to move forward, sideways or backward. Most often, it is treated surgically using transpedicular structures. Objective. To present a clinical case of re-treatment for degenerative lumbar spondylolysis of the LV vertebral body using transpedicular and posterior autografting techniques. Methods. The clinical case of lumbar spine osteochondrosis, spondyloarthritis,posterior transpedicular fusion LV–SI, fracture of the screw in the body of the SI vertebra on the right, and spinal canal stenosis at the level of LV–SI is described. Lower paraparesis. Results. The patient underwent metal removal, decompression of the spinal canal at the level of LV–SI, open reduction of the LV vertebral body, posterior transpedicular fusion of LIV–SI and posterior autografting fusion. The surgical intervention was successful, despite the technical difficulties associated with removing the threaded part of the broken screw. According to the visual analogue scale, the patient had 8 points beforethe operation, which indicates acute pain syndrome, and after that the pain intensity decreased to 4 points. Muscle strength of the right and left lower extremities before surgery was 2 and 2.5 points, respectively, 5 days after surgery, improvement was recorded — 3 points for each limb. From the second day after repeated surgical treatment, the patient showed a significant improvement in muscle sensitivity and strength in both lower extremities.Conclusions. The clinical example of repeated surgery due to the failure of the metal structure and the deterioration of the patient's neurological status highlights the need for postoperative follow-up. Taking into account the percentage of complications after transpedicular spondylodesis, it is necessary tocontinue scientific research to improve the results of surgical treatment of patients with degenerative diseases of the spine.
Adult-Onset Still’s Disease after COVID-19 Vaccination: A Case Report and Review
Authors: Park Jung Wan , Lee Sung Won
Published: June 2023

To overcome the global pandemic of coronavirus disease 2019 (COVID-19), COVID-19 vaccination has been developed and distributed. Many people have received the vaccination worldwide. However, there are some vaccinated individuals who complain of side effects due to COVID-19 vaccination. We report the case of a patient who developed adult-onset Still’s disease (AOSD) after receiving the messenger RNA COVID-19 vaccine. A 21-year-old male patient without a previous medical history developed a fever on the day of the first dose of the vaccine. He had persistent fever, arthralgia of the knee and wrist, hyperferritinemia, transient skin rash, and negative test results for rheumatoid factor or antinuclear antibody. Positron emission tomography-computed tomography scan showed lymphadenopathies with reactive patterns and no malignancy. His symptoms and laboratory abnormalities gradually improved with glucocorticoid, cyclosporine, methotrexate, and tocilizumab treatment. Although its causality is still not confirmed, AOSD should be considered in a case that meets the diagnostic criteria after COVID-19 vaccination.

Nodular histiocytic/mesothelial hyperplasia (NHMH) is a very rare condition. It is generally thought to be associated with repeated mechanical or chemical stimulation. This study reported NHMH with papillary growth pattern in the ovary following high-intensity focused ultrasound (HIFU) treatment for uterine leiomyoma and adenomyosis. A 48-year-old female, who had a history of undergoing HIFU treatment 7 times for adenomyosis and leiomyoma of the uterus 6 months ago, was referred to the hospital. After the hysterectomy and right salpingo-oophorectomy, the patient was confirmedly diagnosed with nodular histiocytic and mesothelial hyperplasia with the papillary growth pattern of the right ovary. This benign reactive inflammatory lesion of the mesothelium mimicking malignancy must be kept in mind to avoid unnecessary treatment.

Castleman’s disease is a rare non-neoplastic lymphoproliferative disorder of unknown origin. It is classified into unicentric or multicentric based on its anatomical distribution. Multicentric Castleman’s disease can be subdivided according to the presence of human herpesvirus-8 (HHV-8) infection. Castleman’s disease has a rare incidence, and HHV-8-positive multicentric Castleman’s disease is even rarer. There are several types of natural course for this disease, and the rapidly progressing type can lead to death within a few weeks, emphasizing the need for prompt diagnosis and treatment. We report a recent case from Korea, presenting with multiple lymphadenopathies, confirmed as HHV-8-positive multicentric Castleman’s disease through biopsy, and achieving complete response with rituximab monotherapy.

The most important pests of acacia black locust (Robinia pseudoacacia L.) (Fabaceae) are: Appendiseta robiniae Gillette, Phyllonorycter robiniella Clemens, Parectopa robiniella Clemens, Nematus tibialis Newman and Obolodiplosis robiniae Haldemann, species from North America, where it also originates the acacia, which is the host plant. In Europe these species were introduced accidentally, being considered invasive species. In Europe, O. robiniae Haldemann was first reported in July 2003 in northeastern Italy, in Paese near Padua, from where it spread to almost the entire European continent, especially through trade in infested biological material from nurseries. The attack occurs in the species R. pseudoacacia L., R. viscosa L. and R. hispida L., mainly in urban areas, where it mainly affects their aesthetic value. The larvae develop characteristic leaf margin roll galls on the infested leaves. There are up to 6 galels on a leaflet, and on average there are up to 5-6 larvae. In Europe it develops two, three and, in optimal conditions, even four generations a year. Zoophagous entomofauna can cause population decline, especially parasitoid species. For Platygaster robiniae Buhl & Duso (Hymenoptera: Platygastridae) the percentage of parasites reported was up to 40%. A low percentage of parasitism can be produced by other species, such as: Aprostocetus sp., Chrysocharis sp. (Hymenoptera: Eulophidae), Eupelmus urozonus Dalman (Hymenoptera: Eupelmidae), Eurytoma verticillata F. (Hymenoptera: Eurytomidae), Mesopolobus mediterraneus Mayr. (Hymenoptera: Pteromalidae) and Torymus sp (Hymenoptera: Torymidae).
