Authors: Xu Xianfeng , Wang Ke , Lu Yong , Tian Yunbo , Hu Liqun , Zhong Ming
Published: October 2023

The vertical integration of ‘Generation-Grid-Load-Storage’ in microgrids for port areas is a prevailing trend. To comprehensively and accurately assess the operational efficiency of microgrids and develop an effective means for promoting the sustainable and scalable development of microgrids in port areas, an applicable evaluation index system and comprehensive evaluation method are essential. Addressing the issues of subjectivity in quantitative evaluation decision-making for different configuration and allocation schemes in port areas and the lack of a comprehensive evaluation system for microgrids in port areas, this study aims to scientifically and reasonably evaluate and select the most optimal configuration and energy dispatching schemes for microgrids in port areas. In this paper, the performance indicators of microgrids in port areas are hierarchically structured and classified into five dimensions: economic, energy efficiency, environmental, system reliability, and safety. A comprehensive evaluation index system for microgrid systems in port areas is constructed. Furthermore, an evaluation model for microgrid operational efficiency based on improved CRITIC-TOPSIS is proposed. The coefficient of variation is introduced to measure the relative strength and relative variation of indicators among dimensions, reducing the impact of correlation between indicators and improving the accuracy and objectivity of the evaluation results. Then, the TOPSIS method is used to calculate the comprehensive evaluation values and rank the optimal microgrid schemes in port areas. Finally, the feasibility of the evaluation index system and evaluation method for the operational efficiency of microgrids in port areas is verified through case analysis. The results indicate that the evaluation method based on improved CRITIC-TOPSIS can objectively and quantitatively evaluate the operational efficiency of microgrids in different port areas. The proposed method reasonably avoids the strong subjectivity in weight calculation by traditional expert judgment during the planning phase of microgrids in port areas, providing a new and scientifically effective engineering evaluation and analysis method for the evaluation of microgrid operational efficiency in port areas.

Authors: Wang Jing , Song Yuhong , Ge Beichen , Zhou Ying
Published: October 2023

Ecological sensitivity measures an ecosystem’s reaction and restoration difficulty to exogenous disturbances. Regional ecological and environmental challenges can be identified using ecological sensitivity evaluation. The regional characteristics and environmental challenges of plateau lakes were quantified to create four assessment indexes: landform, natural conditions, human activities, and ecological security. Eleven ecologically sensitive characteristics were chosen. We evaluated the landscape ecological sensitivity of the Erhai Lake Basin, China, using ArcGIS and the analytical hierarchy process (AHP). The results showed that the Erhai Lake Basin was mostly forest from 1990 to 2020 and that the dynamic land-use attitude increased and then reduced. The cultivated land became mostly woods and grassland. The largest building area was tied to reverting farms to woods and urban construction. The highest weight was from single-factor ecologically sensitive vegetation covering, followed by river systems and roadways, and lowest was from landslides and collapses. The ecologically sensitive areas with more vegetation and a greater distance from roads and woodland are harder to recover from harm. According to the thorough sensitivity analysis, the study region’s high sensitivity area is 1102.36 km2 (26.16%) and the higher sensitivity area is 1177.10 km2 (27.93%). The ecological sensitivity increases from neighborhoods to nature reserves. High-sensitivity areas were in hilly woods and grasslands with few people. The low-sensitivity area was around water and homes. The dynamic stability of the area ecological environment influenced ecological sensitivity. This study aims to provide sustainable land use solutions for the Erhai Lake Basin and a scientific basis for managing and protecting ecologically vulnerable areas.

Published: October 2023

The living spaces within vernacular dwellings undergo continuous adjustments in response to evolving lifestyles, society, and cultural shifts. Residents, guided by their understanding, integrate newly emerging functional spaces within the framework of traditional living environments. While appearing rough and A disorganized, this spontaneous and evolving arrangement of living spaces can reflect how residents incorporate contemporary lifestyles into the framework of traditional dwelling spaces. The research focuses on the traditional earth dwellings in the Inner Mongolia section of the Yellow River basin, aiming to explore the contemporary spatial organization within these local residences. The research uses typology to classify the plans and analysis as the spatial syntax theory to organizational characteristics of residential spaces. With the assistance of the Depthmap X software, Integration and Control Value parameters are computed. Combining the calculated results with the parameters’ meaning determines the following: (1) the plan organization is related to basic functional space types; (2) the stove, used for heating in functional spaces, serves as the center of the plan organization, and the basic functional spaces are typically arranged around this center; (3) both of these space types have extremely high Control Values over directly adjacent spaces and become the core spaces for daily living and activities. Researching the characteristics of local residential space organization and concretely showcasing local residential culture can provide a foundation for future construction that respects residents’ preferences and supports the sustainable development of local residential culture.

Published: October 2023

Short-term load forecasting is a prerequisite for achieving intra-day energy management and optimal scheduling in integrated energy systems. Its prediction accuracy directly affects the stability and economy of the system during operation. To improve the accuracy of short-term load forecasting, this paper proposes a multi-load forecasting method for integrated energy systems based on the Isolation Forest and dynamic orbit algorithm. First, a high-dimensional data matrix is constructed using the sliding window technique and the outliers in the high-dimensional data matrix are identified using Isolation Forest. Next, the hidden abnormal data within the time series are analyzed and repaired using the dynamic orbit algorithm. Then, the correlation analysis of the multivariate load and its weather data is carried out by the AR method and MIC method, and the high-dimensional feature matrix is constructed. Finally, the prediction values of the multi-load are generated based on the TCN-MMoL multi-task training network. Simulation analysis is conducted using the load data from a specific integrated energy system. The results demonstrate the proposed model’s ability to significantly improve load forecasting accuracy, thereby validating the correctness and effectiveness of this forecasting approach.

In the realm of scaffold-free cell therapies, there is a questto develop organotypic three-dimensional (3D) tissue surrogates in vitro, capitalizing on the inherent ability of cells to create tissues with an efficiency and sophistication that still remains unmatched by human-made devices. In this study, we explored the properties of scaffolds obtained by the electrospinning of a thermosensitive copolymer, poly(N-isopropylacrylamide-co-N-tert-butylacrylamide) (P(NIPAM-co-NtBA)), intended for use in such therapies. Two copolymers with molecular weights of 123 and 137 kDa and a content of N-tert-butylacrylamide of ca. 15 mol% were utilized to generate 3D scaffolds via electrospinning. We examined the morphology, solution viscosity, porosity, and thickness of the spun matrices as well as the mechanical properties and hydrophobic–hydrophilic characteristics of the scaffolds. Particular attention was paid to studying the influence of the thermosensitive polymer’s molecular weight and dispersity on the resultant scaffolds’ properties and the role of electroforming parameters on the morphology and mechanical characteristics of the scaffolds. The cytotoxicity of the copolymers and interaction of cells with the scaffolds were also studied. Our findings provide significant insight into approaches to optimizing scaffolds for specific cell cultures, thereby offering new opportunities for scaffold-free cell therapies.
“Pseudo”-Secondary Treatment Failure Explained via Disease Progression and Effective Botulinum Toxin Therapy: A Pilot Simulation Study
Authors: Hefter Harald , Rosenthal Dietmar , Samadzadeh Sara
Published: October 2023

Background: The objective of this study was to provide evidence from a simple simulation. In patients with focal dystonia, an initial good response to botulinum neurotoxin (BoNT) injections followed by a secondary worsening does not necessarily arise from an antibody-induced secondary treatment failure (NAB-STF), but may stem from a “pseudo”-secondary treatment failure (PSEUDO-STF). Methods: The simulation of the outcome after BoNT long-term treatment was performed in four steps: 1. The effect of the first single BoNT injection (SI curve) was displayed as a 12-point graph, corresponding to the mean improvement from weeks 1 to 12. 2. The remaining severity of the dystonia during the nth injection cycle was calculated by subtracting the SI curve (weighted by the outcome after n − 1 cycles) from the outcome after week 12 of the (n − 1)th cycle. 3. A graph was chosen (the PRO curve), which represents the progression of the severity of the underlying disease during BoNT therapy. 4. The interaction between the outcome during the nth BoNT cycle and the PRO curve was determined. Results: When the long-term outcome after n cycles of BoNT injections (applied every 3 months) was simulated as an interactive process, subtracting the effect of the first cycle (weighted by the outcome after n − 1 cycles) and adding the progression of the disease, an initial good improvement followed by secondary worsening results. This long-term outcome depends on the steepness of the progression and the duration of action of the first injection cycle. We termed this response behavior a “pseudo”-secondary treatment failure, as it can be compensated via a dose increase. Conclusion: A secondary worsening following an initial good response in BoNT therapy of focal dystonia might not necessarily indicate neutralizing antibody induction but could stem from a “PSEUDO”-STF (a combination of good response behavior and progression of the underlying disease). Thus, an adequate dose adaptation must be conducted before diagnosing a secondary treatment failure in the strict sense.

Published: October 2023

Coxsackievirus A10 (CV-A10) is a prevailing causative agent of hand–foot–mouth disease, necessitating the isolation and adaptation of appropriate strains in cells allowed for human vaccine development. In this study, amino acid sequences of CV-A10 strains with different cell tropism on RD and Vero cells were compared. Various amino acids on the structural and non-structural proteins related to cell tropism were identified. The reverse genetic systems of several CV-A10 strains with RD+/Vero− and RD+/Vero+ cell tropism were developed, and a set of CV-A10 recombinants were produced. The binding, entry, uncoating, and proliferation steps in the life cycle of these viruses were evaluated. P1 replacement of CV-A10 strains with different cell tropism revealed the pivotal role of the structural proteins in cell tropism. Further, seven amino acid substitutions in VP2 and VP1 were introduced to further investigate their roles played in cell tropism. These mutations cooperated in the growth of CV-A10 in Vero cells. Particularly, the valine to isoleucine mutation at the position VP1-236 (V1236I) was found to significantly restrict viral uncoating in Vero cells. Co-immunoprecipitation assays showed that the release of viral RNA from the KREMEN1 receptor-binding virions was restricted in r0195-V1236I compared with the parental strain r0195 (a RD+/Vero+ strain). Overall, this study highlights the dominant effect of structural proteins in CV-A10 adaption in Vero cells and the importance of V1236 in viral uncoating, providing a foundation for the mechanism study of CV-A10 cell tropism, and facilitating the development of vaccine candidates.

Published: October 2023

Pregnant women are considered to be a population vulnerable to influenza and COVID-19 infections, and the latest guidelines consistently recommend that they receive influenza and COVID-19 vaccinations. A cross-sectional questionnaire-based study was conducted among pregnant women in Poland to determine which factors have the greatest impact on their decision to vaccinate against influenza and COVID-19. A total of 515 pregnant women participated in the study. Among them, 38.4% (n = 198) demonstrated a positive attitude toward influenza vaccination, and 64.3% (n = 331) demonstrated a positive attitude toward COVID-19 vaccination. Logistic regression analysis revealed that the strongest influence on positive attitudes toward COVID-19 vaccination is having it recommended by an obstetrician–gynecologist (OR = 2.439, p = 0.025). The obstetrician–gynecologist’s recommendation to vaccinate against influenza also significantly influences the decision to vaccinate (OR = 5.323). The study results also show a strong correlation between the obstetrician–gynecologist as a source of information on influenza and vaccination and participants’ positive attitudes toward vaccination (OR = 4.163). Obstetricians have a significant influence on pregnant women’s decisions regarding vaccinations. Further recommendations to vaccinate and awareness-raising among obstetricians may be needed to increase the vaccination rate of pregnant women in Poland.

Prevention of infections is crucial in solid organ transplant (SOT) candidates and recipients. These patients are exposed to an increased infectious risk due to previous organ insufficiency and to pharmacologic immunosuppression. Besides infectious-related morbidity and mortality, this vulnerable group of patients is also exposed to the risk of acute decompensation and organ rejection or failure in the pre- and post-transplant period, respectively, since antimicrobial treatments are less effective than in the immunocompetent patients. Vaccination represents a major preventive measure against specific infectious risks in this population but as responses to vaccines are reduced, especially in the early post-transplant period or after treatment for rejection, an optimal vaccination status should be obtained prior to transplantation whenever possible. This review reports the currently available data on the indications and protocols of vaccination in SOT adult candidates and recipients.

Published: October 2023

Cyanide (CN) is a toxic environmental pollutant generated by various industrial activities, necessitating the application of bioremediation techniques for its degradation. Biodegradation is a more cost-effective and environmentally friendly technique with high efficiency in CN removal. This study isolated cyanide-degrading bacteria from Tutupaca mining site soil from Tacna, Peru. Bacillus subtilis strain TT10s was selected for its exceptional capacity to rapidly and completely eliminate cyanide under alkaline conditions (pH 10.5), removing 1000 ppm cyanide within 48 h. A kinetic analysis revealed that the biodegradation follows second-order rate kinetics (k2 = 0.08649 mg/(mg·h), R2 = 0.96622), consistent with the literature attribution of the rate-limiting step to the inducible cyanide dihydratase enzyme, which converts cyanide into ammonia and formate via the Michaelis–Menten model. Fourier-transform infrared spectroscopy (FTIR) spectral analysis further corroborated this enzymatic mechanism, showing the disappearance of CN peaks coupled with the emergence of ammonia (NH) and formate (C=O) peaks. Quantitative kinetic modelling integrated with FTIR profiles and degradation curves implicates cyanide dihydratase as the key rate-controlling enzyme in alkaline cyanide biodegradation without the need for an extra carbon source, generating interest for future bioremediation applications in highly contaminated environments.

Authors: Shen Xin-Tang , Belkin Igor M.
Published: October 2023

This review will serve as an entry point for international researchers who would like to tap into the vast scientific potential of Chinese-language literature on oceanic fronts. We focused on observational physical oceanography studies of marine fronts. A thorough bibliographic search netted 95 papers published in 1982–2023, with a sharp increase in the total number of papers from 2006–2010 to 2011–2015, when this number almost tripled. This trend continued unabated through the early 2020s. The sharp increase in Chinese-language publications preceded by several years a rapid increase in English-language publications in the same field. Regionally, the overwhelming majority of papers is focused on the China Seas, particularly the East China Seas and northern South China Sea. Elsewhere, a number of papers were dedicated to the Southern Ocean and North Atlantic. Thematically, papers on remote sensing of ocean fronts dominate the literature, with special attention to the development of front-detection algorithms that can be applied to satellite data on sea surface temperature, salinity, chlorophyll, and sea level anomaly. Numerous papers on marine fronts in the China Seas present important results that have to be considered by international researchers. Overall, this review emphasizes the significant contributions made by Chinese oceanographers, particularly to studies of the frontal oceanography of the China Seas.

Published: October 2023

Candidatus Accumulibacter belongs to phosphate-accumulating organisms (PAOs) which exhibit a cyclic metabolism and are capable of intracellular polyphosphate accumulation and their hydrolysis under feast-famine anaerobic-aerobic cycling. In consortia of activated sludge microorganisms, these bacteria are responsible for enhanced biological phosphorus removal (EBPR). The spectrum of the substrates used by Ca. Accumulibacter remains insufficiently studied. It was investigated by measuring the oxygen uptake rates (OUR) of Ca. Accumulibacter-enriched culture supplemented with 17 different organic substrates. The highest oxygen uptake rate values were observed in the presence of tryptone, volatile fatty acids (acetate, propionate, and butyrate), succinate, pyruvate, and amino acids (aspartate and glutamate). Phosphate dynamics in the medium under shifts from anaerobic to aerobic cultivation in batch experiments were studied for these compounds (except for tryptone). All tested substrates were shown to cause phosphate cycling (release in the anaerobic phase and uptake in the aerobic one), with OURs for the substrates correlating with the number of phosphates consumed during the aerobic phase. It was concluded that OUR may be used as an indicator of the monosubstrates used by Ca. Accumulibacter in the anaerobic/aerobic cycle. The possible pathways for substrate transport and metabolism by Ca. Accumulibacter are discussed using stoichiometric data and the results of metagenomic analysis.

The study aims to examine the influence of local endometrial injury on the results of thawed embryo transfer programs in patients with endometrial hypoplasia based on the analysis of clinical cases. The author analyzes two clinical cases of performing scratching prior to the implementation of the assisted reproductive technologies program in patients with “thin” endometrium and evaluates its effectiveness. Embryo implantation is a key stage limiting the effectiveness of assisted reproductive technologies, and depends on the receptivity and selectivity of the endometrium, the quality of the blastocyst, as well as on their cross-interaction. At the same time, two-thirds of im-plantation failures may be associated with endometrium impaired susceptibility. Endometrial hypoplasia is believed to be associated with a decrease in the probability of embryo attachment. Various therapeutic approaches have been proposed to improve its receptivity. The technology of local damage to the uterine mucosa was applied before the program of assisted reproductive technologies in two patients with “thin” endometrium. Following the transfer of thawed embryos, uterine pregnancy occurred in both cases, which ended with operative delivery on time.

The study aims to analyze the features of comorbidity and the nature of the course of sepsis in on- cohematological patients. A comparative analysis of the clinical examination and observation data of 25 patients with lymphoproliferative diseases (multiple myeloma and lymphomas) was carried out. The patients were divided into four groups as follows: the first group included patients who had received cytostatic therapy with sepsis complications, while the third group comprised those without complications; the second and fourth groups included patients with autologous hematopoietic stem cell transplantation after the course of cytostatic therapy with and without sepsis complications, respectively. The statistical analysis of the data obtained was carried out with the nonparametric Mann–Whitney test, the χ2 test and Fisher’s exact test were used in the analysis of qualitative indicators with p < 0.05. There were pronounced stages of chronic cardiovascular pathology in groups with sepsis complications, including those with fatal outcomes, which demonstrated the critical importance of vascular disruption as an underlying disease in the development, course, and outcomes of sepsis. In the study of biomarkers reflecting the activity of inflammation and cellular damage, the level of C-reactive protein in both groups with sepsis statistically significantly differed from that of groups without sepsis, while the level of lactate dehydrogenase showed statisti cally significant differences between the first and the corresponding third comparison group. A dramatic increase in the level of lactate dehydrogenase was detected in both groups with transplantation of autologous hematopoietic stem cells with and without sepsis complications. That corresponds to the literature data and is associated with an increase in the level of cell lysis following transplantation. There were no statistically significant differences in the level of thrombocytopenia (a typical marker value) between groups with sepsis and groups without sepsis. The earch for markers of risk and the severe course of sepsis require further research.

La realización de esta práctica a través de un video interactivo hace más atractiva para el alumno el aprendizaje de conceptos que generalmente se les ofrece mediante otras vías más convencionales como consecuencia del número tan elevado de alumnos matriculados en estas asignaturas. Además, les permitirá experimentar el fenómeno termodinámico a partir de varios ensayos, opción no disponible habitualmente como consecuencia de la limitación de espacio y horas de experimentación disponibles, así como por temas de seguridad.
Wildnisbildung: ein Beitrag zur BNE und Desiderat der Primarpädagogik
Authors: Simon Jaqueline , Simon Toni , Lindau Anne-Kathrin
Published: October 2023

Als eine wichtige Voraussetzung für eine Nachhaltige Entwicklung wird hochwertige Bildung gesehen, insbesondere Bildung für nachhaltige Entwicklung (BNE), die darauf abzielt, Menschen zu einem zukunftsfähigen Denken und Handeln unter Nachhaltigkeitsaspekten zu befähigen. Für die Umsetzung einer BNE bietet das Konzept Wildnisbildung spezifische Potenziale. Wildnisbildung knüpft inhaltlich am Thema Wildnis an, das aktuell u.a. hinsichtlich der Kernprobleme des globalen Wandels öffentlich, politisch und wissenschaftlich diskutiert wird und als geeignetes Thema für eine BNE gilt. Wildnisbildung orientiert sich am Leitbild einer Nachhaltigen Entwicklung, folgt den Kompetenzbereichen Erkennen, Bewerten und Handeln sowie den Bereichen Erleben, Sensibilisieren und Transformieren und fokussiert auf das sinnlich-leibliche Erleben von (ver)wilder(nder) Natur.

Gleich beansprucht aber unterschiedliche Ressourcen? Implikationen für einen nachhaltigen Auf- und Ausbau von Ressourcen in inklusiven Settings während des Lehramtsstudiums
Authors: Oetjen Birte , Martschinke Sabine
Published: October 2023

Der Beitrag berichtet von ausgewählten Ergebnissen einer Teilstudie des Projektes POWER (Empowerment für Studierende und Lehramtsanwärter*innen der Primarstufe Belastungen und Ressourcen in inklusiven Settings). Clusteranalysen mit (N =294) Grundschullehramtsstudierenden verweisen auf drei Studierendengruppen, die sich in ihrer Zufriedenheit und Vitalität signifikant unterscheiden. Die Analysen zeigen, dass ein Großteil der Studierenden sich entweder zufrieden, aber tendenziell wenig vital (Cluster 2), oder wenig zufrieden und wenig vital einschätzen (Cluster 3). Während zufriedene und vitale Studierende (Cluster 1) hohe inklusive Ressourcen (inklusive Einstellungen, Selbstwirksamkeitserwartungen, Widerstandskraft) aufweisen, schätzen sich besonders ungünstig beanspruchte Studierende (Cluster 3) nur wenig widerstandsfähig ein. Für das Cluster 3 bildet sich zudem ein heterogenes Ressourcenspektrum in Abhängigkeit vom Geschlecht der Studierenden ab. Es wird diskutiert, inwiefern die Ergebnisse für einen nachhaltigen Auf- und Ausbau von inklusiven Ressourcen bereits in der Lehrer*innenausbildung genutzt werden können und sollten. (DIPF/Orig.)
Making in der Primarstufe und ihrer Didaktik – Deutsch, Mathematik und Sachunterricht in einer von Digitalität geprägten Welt

Published: October 2023

Making bezeichnet im Allgemeinen „Aktivitäten von Selbermacher*innen, die sich (auch) digitaler Werkzeuge bedienen“ (Schön, Ebner & Narr 2020). Damit bietet es Anknüpfungspunkte für fachliche Bildung in der Primarstufe, die im Lichte einer „Kultur der Digitalität“ in besonderer Weise die sich verändernden Lebenswelten aufzugreifen versucht, Fragen von Nachhaltigkeit und nachhaltiger Entwicklung berücksichtigt, damit nachhaltig bildet und zur ko-konstruktiven Auseinandersetzung einlädt. Aus den Arbeitsbereichen der beteiligten Fächer Deutsch, Mathematik und Sachunterricht liegen bereits Konzeptualisierungen eines an die Besonderheiten digitaler Medien angepassten Lernens mit und über Medien vor. Bisher unterrepräsentiert sind jedoch inter- oder gar transdisziplinäre Zugänge der Fachdidaktiken. Das Konzept des Making bietet sich hier auf besondere Weise an, da mit der Projekt- und Produktorientierung des Making auf selbstverständlichere Weise inter- und transdisziplinäre Arbeits- und damit Lernprozesse einhergehen.

Wie gelingen virtuelle Analysen von Unterrichtsvideos im Grundschullehramtsstudium? – Variation der Analysebedingungen in der quasi-experimentellen Interventionsstudie „ViUVi“
Authors: Seger Alina , Hess Miriam
Published: October 2023

Zunehmend werden Unterrichtsvideos im Studium auch virtuell und asynchron analysiert. Diesem Online-Setting werden, neben den allgemeinen Vorteilen des Einsatzes von Unterrichtsvideos, spezifische Chancen zugesprochen. So kann beispielsweise der eigene Lernprozess flexibler organisiert und gestaltet werden. Allerdings hängt die Wirksamkeit der virtuellen Analyse von Unterrichtsvideos von deren konkreten Ausgestaltung ab. Besonderes Potenzial bietet dabei der gemeinsame Austausch. Da bislang kaum untersucht wurde, inwieweit die Bedingungen (Austausch, zeitmarkenbasierte Annotationen) Studierende bei Online-Unterrichtsvideoanalysen tatsächlich unterstützen können, wird dieser Frage in einer quasi-experimentellen Interventionsstudie nachgegangen. Vier Gruppen, bestehend aus Grundschullehramtsstudierenden in einem Grundlagenmodul der Universität Bamberg, mit jeweils verschiedenen Settings zur virtuellen, asynchronen Analyse von Unterrichtsvideos, werden dabei verglichen.

Was Kinder von Lerngesprächen erwarten – Lerngespräche im Spannungsfeld von Erwartungen und Bedürfnissen
Authors: Knapp Damaris
Published: October 2023

Lerngespräche dienen der lernförderlichen und unterstützenden Begleitung des Lernens von Schüler*innen. In diesem Beitrag wird die Perspektive von Kindern fokussiert mit der Frage, wie Kinder Lerngespräche verstehen und was sie von ihnen erwarten. Zunächst wird die Gesprächsform „Lerngespräch“ begrifflich geklärt und theoretisch eingeordnet. Ausgehend von einer explorativen Studie an Grundschulen werden zentrale Ergebnisse zu den Erwartungen von Schüler*innen dargestellt und diskutiert. (DIPF/Orig.)
“El yo epistémico lúdico”: una presencia en los educadores que enseñan matemática en los primeros grados
Authors:   , Sampaio Velasco Zultonney Flávio
Published: October 2023

Esta investigación tiene como objetivo indagar, a partir de la idea del “Yo Epistémico” de Bernard Charlot, los puntos característicos del “Yo Epistémico Lúdico” en educadores que enseñan Matemática y verificar cómo este se manifiesta/comporta en el proceso de producción del saber matemático en la sala de clase. Esta comprensión está asociada a cómo el educador, a partir de su práctica docente, organiza, produce y realiza actividades lúdicas en la enseñanza de la Matemática para alumnos de la enseñanza primaria (1º al 5º año). Esto se da en las formas de revisar, recordar, rescatar de la memoria una lúdica infantil, juvenil, o incluso en jugueteo adulto, en grupos familiares que rodean al educador, con la función de interpretar, reorganizar, reinventar, adaptar estas actividades para su contexto escolar en la sala de clase. La fundamentación teórica se basa en los estudios de Bernard Charlot con sus concepciones sobre: el yo epistémico y la relación de saber, así como en los estudios de otros autores sobre la memoria, la lúdica, la infancia, entre otros. Las unidades de análisis fueron 10 escuelas del municipio de Belém y 4 del municipio de Ananindeua, en el Estado do Pará - Brasil y los sujetos de la investigación fueron 80 educadores de la Enseñanza Básica Primaria. La recolección del material para la investigación se realizó a través de: observación directa; respuestas a cuestionarios; entrevistas informales; y apuntes en los registros de los diarios. Los análisis de los datos están dispuestos en el orden de los instrumentos – observación directa y registros en diarios, entrevistas, inventarios de saberes. Las primeras muestras de los análisis mostraron en los inventarios de saberes las ocurrencias más relevantes de los educadores que enseñan matemática, de los aprendizajes aunados al desarrollo personal, relacional, afectivo y profesional. El trípode entre: la perspectiva identitaria – que confirma la expectativa, condiciones y referencias de los educadores sobre el saber matemático y lúdico se revelaron como características para el proceso de construcción de lo que llamamos el “yo epistémico lúdico”; la perspectiva epistémica – en cuanto a la necesidad de la formación específica de contenidos matemáticos; y la perspectiva social –marcada por relaciones entre educadores, alumnos, aprendizajes y saberes matemáticos.
Multietiological abortion induced by Brucella melitensis and Chlamydophila abortus in a sheep fetus
Authors: DENİZ İbrahim , ORUÇ Ertan
Published: October 2023

In this case, multietiological abortion due to Brucella melitensis (B. melitensis) and Chlamydophila abortus (C. abortus) agents was defined in a sheep abortion. An aborted sheep fetus submitted to Konya Veterinary Control Institute (KVCI) from a sheep farm in Nigde province in Brucella spp. presence was determined by bacterial isolation method and confirmed by slide agglutination test with monospecific A and M sera. C. abortus was detected by real time PCR and immunohistochemistry (IHC) methods. In histopathological examinations, in the lung; hyperemia, hemorrhage and bronchopneumonia, In the heart; in the placenta with degeneration and necrosis of heart muscle cells; hyperemia, hemorrhage, edema, necrosis and mononuclear cell infiltrations were observed. In this study, it was emphasized that in the fight against sheep abortions, multi-etiological abortions involving more than one factor should be taken into consideration, as well as an etiological agent, and it would be appropriate to use multidisciplinary diagnostic methods to determine the abortion factors, thus contributing to the prevention of abortions, which is still an important problem in sheep breeding.
