Erster Hort aus der Hallstattzeit in Ostböhmen (Stíčany, Bez. Chrudim)
Authors: Jiráň Luboš , Jílek Jan , Vích David
Published: March 2023

Am 8. Februar 2014 wurde an einer beim Pflügen zerstörten Stelle im Katastergebiet von Stíčany in dem Bezirk Chrudim eine Ansammlung von Bronzeartefakten und Bernsteinperlen entdeckt, ein Fund, der unsere Vorstellungen zum erreichten Kenntnisstand der Hallstattzeitforschung in Böhmen korrigiert.

Die bisherige Erfahrung deutete darauf hin, dass die entsprechende Quellenbasis bereits soweit erschlossen war, dass die einzelnen lokalen Kultureinheiten nicht nur räumlich, sondern auch dinglich und inhaltlich zuverlässig bestimmt werden konnten, und dass eine detaillierte Verwandtschaft gegeben war. Zur einfachen Einordnung von Funden stand eine Chronologie zur Verfügung. Während neu erworbene Funde diese Vorstellung typischerweise bestätigten, widerspricht der hallstattzeitliche Hort, dem dieser Artikel gewidmet ist, deutlich. Immerhin handelt es sich hier um den ersten wirklich unbestreitbaren Hortfund aus der Hallstattzeit in Böhmen. Auf den ersten Blick ist diese Assemblage einzigartig, nicht nur wegen ihres Solitärcharakters und weil ihre Zusammensetzung die gegenwärtige Vorstellung artefaktischer Kompositionen in der tschechischen Schlesisch-Platěnicer Kultur der Hallstattzeit erheblich verändert, sondern vor allem, weil sie neue Erkenntnisse über kulturelle Zusammenhänge nach sich zieht. Es entsteht nun die Möglichkeit, neue Interpretationen zur Funktionsweise der Gesellschaft am Übergang von der jüngeren zur späten Hallstattzeit und über interkulturelle Beziehungen dieser Zeit im breiteren europäischen Raum zu wagen.
Constructing Monastic Landscapes of Southern Syria in Late Antiquity
Authors: Ashkenazi Jacob
Published: March 2023

While monastic landscapes in arid surroundings can be more easily defined, interpreting the imprint of monks on rural arable landscapes is more challenging. In the current study, I face this challenge by examining a late antique rural landscape, the fertile Vulcanic plains of southwest Syria, in the light of the document known as “the letter of the archimandrites of Arabia.” Analyzed by the distinguished orientalist Theodore Nöldeke in 1875, the letter is a declaration of faith, written in Syriac, dated to 570 and signed by 137 signatories, most of whom held the title of abbot (resh dira in Aramaic). Quite a few scholars have dealt with this letter and extracted valuable information out of its lines. In the following presentation, I will concisely review the various viewpoints from which they scrutinized the letter and offer an additional reading: a reading of a cultural landscape in which monasticism is a significant designer. Since archaeological records of monastic manifestations in this area are sparse and debated, I will use a comparative study of nearby rural landscapes that were surveyed during the last decades to facilitate a spatial interpretation of the monastic landscape encapsulated in and between the lines of the letter.

Published: March 2023

Background and aims: We sought to examine the interaction between CRY1 genotypes and low carbohydrate diet (LCD) score and the effect on insulin resistance, insulin sensitivity, homeostasis model assessment of insulin resistance (HOMA- IR) and quantitative insulin sensitivity check index (ISQUKI).
Methods: This cross-sectional study was conducted with a total of 228 overweight and obese women. The data related to anthropometric and biochemical measures were collected and a food frequency questionnaire (FFQ), with 147 items, was used to assess dietary intake. Based on the FFQ, we calculated an LCD score for each study participant, ranging from 0 to 70. Biochemical assessments, including TC, HDL, LDL, TG, FBS, insulin and HOMA-IR, were performed. Deoxyribonucleic acid (DNA) samples were assessed to be genotyped for the rs2287161, which was genotyped by the restriction fragment length polymorphism (PCR-RFLP) method. A generalised linear model was performed for interaction analysis.
Results: The results of the study demonstrated that, after controlling for several confounders, increased adherence to an LCD (T3 vs. T1) in the interaction with one risk allele genotype (CG) increases ISQUKI level (β: 0.001, CI: 0.00, 0.002, p=0.041). Also, there was a marginally negative interaction between higher adherence to LCD and two risk alleles genotype (CC) on insulin level (β: -0.012, CI: 0-0.024, 0.001, p=0.054).
Conclusions: This study revealed a negative interaction of CRY1 genotypes with two risk allele and higher LCD adherence on insulin level, and a positive interaction on ISQUKI. However, the mechanism of interaction between LCDs and CRY1 genotypes remains unclear.

Published: March 2023

Fused deposition modeling (FDM) is a well-liked additive fabrication method used to manufacture prototypes and components in industries. The quality of the 3D printed component depends on the temperature profile between the layers of the printed components and the process parameters. The deviations in the quality of manufactured components can be established using tools of metrology, including Coordinate-Measuring Machine and Machine Vision. This research is to determine the effect of temperature on the aforementioned phenomenon by using collected data to build a predictive model. The leading factor effect intrigue is stressed for the correlative closeness coefficient (Cn*) and Technique for Order of Preference by Similarity to Ideal Solution(TOPSIS). The most favorable combinations of the experiment were obtained from the response diagram at a layer thickness of 0.3 mm, print speed of 80 mm/sec, and infill percentage of 20%. It is noted that the parameters have a contribution of 55.60%, 33.16%, and 0.15%, respectively. The majority of agreeable combinations of the investigations were acquired from the main factor effect response diagram, a layer thickness of 0.3 mm, printing FDM speed of 80 mm/sec, and an infill percentage of material is 20% for maximizing the temperature gradient and minimizing shrinkage and warpage. A fuzzy logic expert system was used to predict the shrinkage allowances precisely with less than 5% error.

Authors: Meethum Piyanut , SUVANJUMRAT CHAKRIT
Published: March 2023

Hydroplaning is a hydrodynamic phenomenon and has crucial effects on motorcycle tires that roll on a wet road at high speed. It causes an accident that results in numerous injuries and deaths of motorcyclists. This accident happens to an overestimation of the dynamic tire performance. Therefore, this research aims to propose a mathematical model to predict the maximum hydroplaning speed of motorcycle tires. The motorcycle tire was experimentally performed the hydroplaning test by the developing machine. The fluid-structure interaction (FSI), in which a rolling tire interacted with fluid on the road, was modeled using finite element and finite volume methods. It compared against the experiment and was in good agreement. Therefore, motorcycle tire hydroplaning was studied by varying velocities, inflation pressures, and carrying loads. It was found that the hydroplaning speeds had a serious relationship only to the carrying loads. Therefore, the novel function of hydroplaning velocity was established in the carrying load form. It is simple to specify the maximum hydroplaning speed of motorcycle tires. In addition, it will be a good and novel guidance tool for motorcycle riding communities and motorcycle tire manufacturers to calculate hydroplaning resistance of their motorcycle tires.

Published: March 2023

Morphological matrix-based conceptual design has been proven to enable the generation of high-quantity, variety, and novelty concepts. Indeed, many studies have proposed methods for enhancing it. However, logical relations for determining the compatibility of solution principles (SPs) in combinatorial solution chain is yet to be established in the literature. This study attempts to develop a logical relation for determining the compatibility of SPs in solution variants chain. The features of the interaction boundary of each solution principle were characterised and vectorially numerated for onward matching of adjacent SPs in a combinatorial solution chain to determine compatibility. The consistency of the compatibility determinant (CD) was tested on engineering designer students. It was found that the students could determine the CD with excellent consistency. Besides, the applicability of logical relation for determining the feasibility of solution variants was tested and found applicable in many trials. Despite the limitation of the study, the results indicate that the logical compatibility determinant is consistent and applicable for the complete exploration of the morphological matrix design space. Therefore, this study provides a foundation for the development of a reliable CAD system for conceptual design.

Published: March 2023

In order to detect the size and shape of defects inside wood, a propagation velocity model of stress wave in the longitudinal section of trees in different direction angles was proposed and evaluated. The propagation velocity model was established through theoretical analysis. Four representative tree species in the northeast region of China were taken as test samples. The propagation velocity of stress wave in the longitudinal section of trees in different directions was measured using a nondestructive testing instrument. The corresponding regression model was obtained, which was in good agreement with the theoretical mathematical model. For the larch log samples, a healthy multiple regression model (z = 109.2×2 – 182.1y2 + 36.78x2y2 – 34.76x2y4 + 1627) with correlation coefficient R2 = 0.97 and root mean square error RMSE =17.81 was used to conduct two-dimensional imaging of defective logs. Based on the results of two-dimensional imaging, the highest fitness of the images was 94.24%, and the lowest error rates of defect cavities was 6.11%. The imaging results showed that this method accurately detected the internal defects of trees and was not affected by the size of defects.

Authors: Lagos Zita , De Mattos Pimenta Cibele Andrucioli , Urrutia María Teresa
Published: March 2023

Objective: To construct and validate the Nursing Warmth Scale (NWS) through the development of a standardized measurement of nurses' warmth, perceived from the perspective of patients, and identify the behaviors and factors associated with this feeling of warmth.
Materials and methods: The NWS was developed following the scale construction methodology under a triphasic model. The construction of items was elaborated based on the results of a previously published integrative review that consolidated the construct and the related variables. A qualitative phase was also incorporated to evaluate the latent variable. Content validity was assessed with 10 expert judges. An item try-out was conducted with 476 patients in health institutions. Exploratory factor analysis —through the common factor method and oblique rotation— was used for the item reduction process.
Results: The construct “Nursing Warmth” was established after the theoretical and empirical phases of the study. The literature review and interviews with 23 patients and 25 nursing professionals provided a set of behaviors divided into 2 categories: verbal and nonverbal behaviors. Exploratory factor analysis allowed identifying 5 factors and 35 items. The reliability was estimated through Cronbach's alpha. The identified factors are: F1-Nonverbal connection-relationship with the other (0.943), F2-Empathy (0.909), F3-Verbal connection-relationship with the other (0.914), F4-Inclusion (0.858), and F5-Confidence (0.852). The Tucker-Lewis Index was 0.901.
Conclusions: The NWS demonstrates evidence of reliability and validity. This tool may be useful in clinical settings and for teaching and research addressing interpersonal nursing skills.

Authors: Ramos Garzón Judy Ximena , Achury Beltrán Luisa Fernanda , Rojas Lyda Zoraya
Published: March 2023

Introducción: a nivel mundial, cada año cerca de 300.000 niños entre 0 y 19 años son diagnosticados con cáncer. El porcentaje de supervivientes va en aumento, llegando a 80 % en países desarrollados y 60 % en América Latina. Sin embargo, la expectativa y la calidad de vida de estas personas pueden verse comprometidas ante el desarrollo de cardiotoxicidad, un efecto adverso asociado al uso de algunos agentes antineoplásicos, como los antracíclicos.Objetivo: resaltar los aspectos clínicos relevantes para la prevención, detección oportuna, tratamiento y seguimiento de la cardiotoxicidad secundaria a la administración de antraciclinas durante la infancia.Síntesis de contenido: reflexión teórica que presenta consideraciones clínicas relevantes para guiar las acciones de enfermería y del equipo multidisciplinario en la atención y el cuidado de la salud cardiovascular de los supervivientes de cáncer a cualquier edad. Es importante destacar que en población pediátrica la única estrategia efectiva de prevención primaria para cardiotoxicidad por antraciclinas es la administración de dexrazoxano, mientras que la prevención secundaria debe incluir detección oportuna, control y  seguimiento de las alteraciones de la función cardíaca y de los factores de riesgo cardiovascular. Por su parte, la prevención terciaria se centra en el control de la enfermedad y el manejo farmacológico. Conclusiones: no existe un  tratamiento estándar para la cardiotoxicidad inducida por quimioterapia o radioterapia, siendo el objetivo principal de este tipo de tratamientos prevenir o retrasar la remodelación del ventrículo izquierdo. Todos los supervivientes requieren seguimiento vitalicio y búsqueda activa de signos de cardiotoxicidad, siendo fundamental la acción conjunta de diferentes profesionales y la consolidación de los servicios de cardio-oncología.

Authors: Díaz-Brochero Cándida , Diaz-Tribaldos Diana Carolina , Arteaga-Díaz Juan Manuel , González-Villa Ana María , Peralta Franco Jhon Jairo
Published: March 2023

Resumen
Introducción. El seudohipoparatiroidismo (SPT) es un trastorno genético poco frecuente que se caracteriza por la resistencia a la hormona paratiroidea (PTH). En Colombia existen pocos reportes sobre esta enfermedad, por lo que la publicación del presente caso contribuye a aumentar el interés en su búsqueda en el ámbito clínico.
Presentación del caso. Hombre de 18 años con antecedente de hipotiroidismo (diagnosticado a los 4 meses de nacido), retraso del crecimiento, desarrollo puberal tardío, obesidad, braquidactilia, fracturas patológicas, osteocondroma femoral, insomnio, parestesias y estreñimiento crónico, quien asistió al servicio de endocrinología de un hospital de tercer nivel de Bogotá (Colombia) remitido luego de haber estado hospitalizado por un episodio convulsivo. En dicha hospitalización los laboratorios evidenciaron hipocalcemia, hiperfosfatemia y 25-OH vitamina D en rango de insuficiencia con niveles elevados de PTH, y los estudios imagenológicos demostraron osificaciones heterotópicas y calcificaciones de ganglios basales del cerebro. Al paciente se le realizó un estudio genético que confirmó el diagnóstico de SPT1A, por lo que se le inició manejo con suplencia de calcio, colecalciferol y quelantes de fósforo, con lo cual evolucionó satisfactoriamente. Tanto el paciente como sus familiares de primer grado recibieron asesoramiento y valoración interdisciplinaria.
Conclusiones. El SPT1A es un trastorno genético complejo poco conocido pero de alta importancia clínica dentro de los diagnósticos diferenciales de hipocalcemia que debe considerarse ya que sin el diagnóstico y tratamiento oportunos, los pacientes pueden presentar consecuencias metabólicas graves y potencialmente fatales.
Zoé, bíos y biopolítica. Instrumentos para la administración de la vida desde el poder político
Authors: Hernández-Gamboa Rodrigo
Published: March 2023

La gestión, administración y disciplinamiento de la vida biológica desde el ejercicio del poder político en la modernidad se ha denominado biopolítica. El objetivo de este artículo fue examinar la constitución etimológica del concepto en su discernimiento con la vida entendida como zoé, es decir, como una vida virtuosa. En la antigüedad zoé formaba parte inherente del poder político, no obstante, en el siglo XVI se generó una transición hacia el bíos, como vida entendida en su naturalidad biológica que fue fundamental para el establecimiento del Estado moderno. Desde una metodología hermenéutica este artículo distinguió la relevancia del bíos para el ejercicio del poder político, concluyendo con la sacralidad del bíos para la organización política en la modernidad.
Biopolítica y cirugías plástico-cosméticas: ¿el discurso médico como estrategia de control?
Authors: Arroyo-Rojas Lellanis , Vallejo-Saldaña Francisco-Javier
Published: March 2023

Las decisiones tomadas en la cotidianeidad están orientadas por significados construidos y heredados, no neutros y que instituyen realidades. El presente texto tiene como objetivo dar cuenta de las estrategias de control ejercidas sobre el cuerpo por medio del discurso médico en el espacio de las cirugías plástico-cosméticas. Nos suscribimos a un análisis cualitativo inductivo del discurso, para indagar en la constitución de significados como salud y belleza dentro de la práctica médica, cabe resaltar que la lente teórica para analizar estos discursos parte de la analítica biopolítica. Concluyendo finalmente, que el discurso médico atiende al orden anatómico-quirúrgico que delimita diversas estrategias de control sobre los cuerpos y la vida; contribuyendo así, a la normalización de significados como “saludable” y “bello”.
Responsibility to Reconcile: Adopting New Terms to Foster Recognition
Authors: Espejo María-Paula
Published: March 2023

The present article is the second of a three-series collection of articles that analyze the power of language to introduce a new set of concepts in contexts where societies can foster peacebuilding in post-conflict scenarios. I build up on Hannah Arendt’s moral responsibility work to understand the need to analyze responsibility in transitional justice frameworks while landing it on peacebuilding discussions. The article advances in how this concept can contribute to fostering recognition, the role it plays in [re]building civic trust and, ultimately, promoting reconciliation. This study is motivated to find a way to engage civil society in the process where social grounds are rethought on respect as a basis. I present a proposal to use the concept of responsibility while suggesting a definition circumscribed to the context of peacebuilding during transition processes.

El reemplazo de las elites en Venezuela. Una explicación a partir del conflicto entre gobierno y medios de comunicación
Authors: Zambrano Andrés
Published: March 2023

El objetivo del artículo fue identificar la naturaleza sociológica del proceso político ocurrido en Venezuela durante el Gobierno de Hugo Chávez Frías. Esta investigación se realizó a partir del análisis de contenido de fuentes documentales y se reconstruyeron los hechos más relevantes desde 1999 hasta 2006, tomando como caso ejemplar el conflicto entre el Gobierno y los medios de comunicación privados. A partir de la filosofía política de Claude Lefort sobre el poder y la democracia, así como el concepto antropológico de institución de Fauconnet y Mauss. se concluye que desde 1999 el principal proceso político ocurrido en Venezuela es un reemplazo de elites. En consecuencia, el punto de inflexión de la democracia venezolana es anterior a esta fecha. El orden político del país ya se encontraba sumergido en un proceso autoritario antes de la llegada de Hugo Chávez Frías; sin embargo, la mayoría de los análisis publicados sobre su Gobierno tratan de una degradación de la democracia.

Respiratory syncytial virus (RSV) is one of the most interesting respiratory viruses in the world. This virus causes symptoms of illnesses like influenza and imposes a heavy burden on medical services and the economy. However, studies on RSV in Vietnam are limited, while most of the RSV research has primarily been done before 2015. We collected the clinical respiratory samples from severe acute respiratory infection (SARI) patients to screen for RSV by real-time RT-PCR and study their molecular characteristics. RSV-positive specimens with Ct value < 25 collected between 2017-2018 in north Vietnam were inoculated on the Hep2 cell line. The results showed that 25 (22.32%) RSV virus strains were harvested from the inoculation procedure with 18 RSV A and 7 RSV B. The whole genomes of four representative strains were sequenced with the Illumina iSeq 100. Phylogenetic trees analysis of each subtype were classified as two RSV A and two RSV B sequences as genotype ON1 lineage 1.2 and genotype BA9 respectively. These genotypes were identified as typical Vietnamese strains from 2009-2012. Nevertheless, the RSV strains before 2015 and those in this study had significant differences in the G gene, with 34–35 amino acids in RSV A and 4 amino acids in RSV B. Moreover, the first whole genome of Vietnamese RSV since 2016 may give more understanding of the molecular characteristics of RSVs in Vietnam.

Currently, nearly 36.5 million people live with Alzheimer’s disease worldwide, and acetylcholinesterase inhibition is considered the main treatment strategy against it. Seaweeds (or macroalgae) are a natural source of high-value bioactive compounds and have great potential in the production of health foods/foods, pharmaceuticals, cosmetics, animal feeds, biofertilizers, and biofuels. The most studied and applied seaweed species include red seaweed (Rhodophyta), green seaweed (Chlorophyta) and brown seaweed (Phaeophyta). This study aimed to evaluate the antioxidant and neuroprotective activities of extracts/substances isolated with solvents including ethanol 75o and 96o, water, n-hexane, ethyl acetate under normal and ultrasonic conditions (power 80W, frequency 4.7 kHz and for 1 hour) from 5 economically important seaweed species belonging to genera Caulerpa, Sargassum, Gracilaria, Ulva and Kappaphycus collected in Ninh Thuan and Khanh Hoa provinces, Vietnam. The results have shown that 05/30 extracts and substances (including SaE96S, SaH, SaHW, SaEA and fucosterol) isolated from five seaweed species exhibited high antioxidant activity through the free radical screening method using 2,2-diphenyl-1-picrylhydrazyl (DPPH) (with EC50 values < 5 mg/mL for extracts and EC50 value < 2 mM for substance) in comparison with positive control ascorbic acid (EC50 = 0.015 mg/mL); acetylcholinesterase inhibitory activity using acetylcholinesterase inhibitor screening KIT (with IC50 values of < 200 µg/mL for both extracts and substances), compared with positive control galantamine (with IC50 value of 52,8 µg/mL). The extracts/substances were able to protect the cell against cytotoxity in the C6 alzheimer’s disease cell model induced by amyloid beta-protein fragment (Aβ25-35). The results achieved from this research have proven that the extracts/substances isolated from seaweed species were a potential source of medicinal agents for the prevention and treatment of alzheimer’s disease.

Balanites vietnamica is described as a new species from Nui Chua National Park in Ninh Thuan province, Vietnam. It is morphologically close to and has been misidentified as B. roxburghii but actually differs in many vegetative and reproductive characteristics. The new taxon is found narrowly endemic in the semi-arid Phan Rang region and its distribution area has been much reduced. The new taxon is described, illustrated with field photographs of detailed botanical characteristics and compared to related species. This rare taxon is assessed as CR following the IUCN Redlist Categories.

Zooplankton often migrates within the water column for different purposes but mostly to find food and avoid predators. Vertical migration over 24 hours is called diel vertical migration (DVM). However, knowledge of DVM for different zooplankton species is limited. The present study analysized DVM based on species distribution in the water column at each different times of day at two stations on the central Vietnam shelf. One station was on the shelf (LT2) and another was on the shelf slope (FK002). The results showed that 69 zooplankton species, out of 191 recorded at the two stations, having strong DVM (dz > 15 m). Among them, 38 species were nocturnal and 36 species showed reverse DVM. Species with nocturnal DVM were less on the shelf station than on the shelf slope. Moreover, detailed analysis at LT2 showed 18 species having DVM at dawn and 13 species having DVM at sunrise. This study provides important data for zooplankton ecology in Vietnam and marine tropical waters.

Cephalotaxus mannii Hook. f. is a rare evergreen conifer native listed in the International Union for Conservation of Nature (IUCN) Red List, which is utilized for leukemia treatment. Although endophytic fungi from C. mannii was reported before, their cytotoxic property has not been revealed yet. In the present study, a total of 7 endophytic fungi were isolated from C. mannii collected in Ha Giang province, Vietnam, among which the isolate WQF18 was active against 5 tested pathogens with inhibition zones ranging from 18.0 ± 0.7 to 25.0 ± 0.4 mm. In addition, only ethyl acetate extract of isolate WQF18 showed cytotoxicity on A549 and MCF7 cell lines with IC50 values of 69.6 ± 2.3 µg/mL and 78.6 ± 1.6 µg/mL, respectively. PCR-based molecular screening revealed that the positive hits for both 10-deacetylbaccatin III-10-O-acetyl transferase (dbat) and taxadiene synthase (ts) genes involved in paclitaxel biosynthesis were only observed in the WQF18 isolate. Based on morphological and molecular identification, the WQF18 isolate was identified as Talaromyces wortmannii WQF18. The presence of paclitaxel in T. wortmannii WQF18 was further confirmed by dbat sequence alignment, phenotypic, and HPLC-DAD analysis. To the best of our knowledge, this is the first report demonstrating the paclitaxel-producing capability of endophytic fungi from C. mannii. These findings provide a new platform for deciphering paclitaxel biosynthesis of endophytic fungi from non-Taxus plants and further paclitaxel production.

Published: March 2023

Rainfall infiltration on the slope increases pore-water pressure in the soil/ rock mass and may cause landslides. Therefore, the precipitation, pore-water pressure and displacement show the kinematic variation of a landslide. In recent years, several approaches have been proposed to investigate the kinematic behavior. Among them, the combination of time series data and geotechnical model has demonstrated its effectiveness in stage classification of landslide kinematics. This paper aims to analyze and classify the stages of landslide kinematic variation with integrating weather and geotechnical monitoring data of Tan Son market landslides. The real-time monitoring station for Tan Son slow-moving landslides were equipped with fixed-in-place inclinometer probes and standard pore-water pressure sensors. The results show that landslide kinematics consist of three stages: stabilization, accumulation, and displacement. The displacement of the landslides was heterogeneous process. The velocity of the landslides significantly increased when the pore-water pressure ratio (ru) at the sliding surfaces > 0.53. While it is almost impossible to notice any displacement when the ratio r­u < 0.45. During the displacement state, the trend of inverse velocity variation gradually decreases to near zero hour/mm. In addition, early warnings of landslide can be released based on the kinematic stages and changes in inverse velocity in this study.
HISTÓRIA LOCAL NO DOCUMENTO CURRICULAR DO ESTADO DO PARÁ

Published: March 2023

O objetivo do artigo é problematizar a forma como está inserida a história local no Documento Curricular para Educação Infantil e Ensino Fundamental do Estado do Pará de 2019 (DCEPará), relacionando a presença dessa temática com os estudos teóricos sobre a história local e currículo. A pesquisa é documental, e, a partir das técnicas de análise de conteúdo de Bardin (2011), concluiu-se que, ao mesmo tempo em que há avanços com a presença de habilidades e objetivos de aprendizagens que acionam a história local de maneira crítica, há contradições entre as intenções e o que realmente é realizado no currículo. A forte presença da lógica quadripartite do conhecimento histórico, da história nacional situada no Sudeste e de papéis secundários para sujeitos como indígenas e negros contradizem um documento que afirma fazer do espaço amazônico eixo central do currículo.

Authors: Rios Pedro Paulo Souza
Published: March 2023

O presente estudo buscou discorrer acerca das relações de gênero e sexualidade na Educação de Jovens e Adultos – EJA a partir das práticas de currículo, por considera-las importante no processo pedagógico dos/as estudantes dessa modalidade de ensino, tendo por objetivo refletir de que maneira as questões as subjetivações de gênero sexual são problematizadas no currículo da Educação de Jovens e Adultos, numa escola da rede pública municipal, localizada no Território de Identidade do Piemonte Norte do Itapicuru, no Estado da Bahia. No que se refere aos procedimentos metodológicos optamos pelas narrativas (auto)biográficas, por entender que esse método de pesquisa favorece o estudo em questão, no sentido de possibilitar maior capacidade de análise no que tange ao objetivo proposto. A partir das narrativas foi possível evidenciar que as questões de gênero, sexualidade e diversidade precisam serem problematizadas dentro da escola, para que a mesma possa se constitui enquanto espaço de respeito às diferenças.
OLHOS DE VIDRO, “BLACK MIRRORS”

Published: March 2023

O presente artigo toma de empréstimo uma frase de um famoso canal televisivo – “Não é TV. É HBO!” – e a reformula no sentido de mostrar um panorama investigativo que evidencia a emergência de um determinado artefato cultural: as narrativas midiáticas seriadas. O objetivo é o de evidenciar que uma narrativa seriada “Não é TV. Mas é currículo!”, a partir de contribuições das teorizações pós-críticas em intersecção com o campo dos estudos culturais. O argumento é o de que esse currículo tem disponibilizado uma “prática da maratona” que reforça a dimensão biopolítica da constituição de uma “cultura seriadora”, que não se encerra no objeto que aqui investigamos, sendo capaz de se estender a diferentes aspectos das nossas vidas, com diferentes efeitos em nossas composições como sujeitos. Com isso, passamos a significar o currículo das narrativas midiáticas seriadas como um agenciamento biopolítico desterritorializado, isto é, uma combinação de elementos díspares cujas redes constitutivas caracterizam-se fundamentalmente pela total ausência de fronteiras, atravessando um território ilimitado que não pode ser confinado por barreiras inamovíveis. Na produção dessa “cultura seriadora”, atentamos para a regulação da vida social da audiência em um exercício particular de poder, tramando-lhe em uma rede discursiva que tem demandado múltiplas posições de sujeito para comportar o máximo possível de indivíduos. Concluímos que há aqui em jogo uma “narcotização programada da vida”, capaz de provocar o empalidecimento das nossas potências, o congelamento das nossas forças vitais e a proliferação das formas estáticas e estabilizadas a partir de redundâncias subjetivas.
O PAPEL REGULADOR DO COMITÊ GESTOR DA BASE NACIONAL COMUM CURRICULAR NA ELABORAÇÃO DA PROPOSTA CURRICULAR DA PARAÍBA

Published: March 2023

Neste artigo objetivamos analisar o papel assumido pelo Comitê Nacional de implementação da Base Nacional Comum Curricular (BNCC) na construção da Proposta Curricular da Paraíba. Para tanto, realizamos uma leitura crítica do papel do referido Comitê, no intuito de compreender o processo de formulação da referida Proposta. Com tal propósito,desenvolvemos uma pesquisa qualitativa, conjugando com a documental e a empírica. Nesta última, elegemos como sujeitos um representante do comitê gestor e quatro da assessoria técnica que atuaram na elaboração da Proposta, especificamente, da parte que trata da educação infantil. Constata-se, pois, que todos os passos de como proceder a reestruturação curricular já havia sido pactuado pelo Comitê Nacional, representado por integrantes do Ministério da Educação, União Nacional dos Dirigentes Municipais de Educação, Conselho Nacional de Secretários de Educação, Fórum Nacional dos Conselhos Estaduais de Educação e a União Nacional dos Conselhos Municipais de Educação, materializando-o no Guia de Implementação da BNCC. Desse modo, pretendeu-se realizar uma regulação de todo o processo de formulação para garantir o alinhamento à BNCC, limitando às ações e decisões da Comissão Estadual. Destacamos que há a resistência, por parte de diversas entidades educacionais, a tais documentos curriculares que objetivam alinhar à educação à lógica do mercado, além de que a complexidade das práticas pedagógicas revela que não são as determinações via decretos que modificam o fazer docente, embora possam influenciá-lo.
