Published: September 2024

Introducción. El avance legislativo en el reconocimiento de derechos de las personas homosexuales en España no ha supuesto que las aulas dejen de ser espacios poco seguros para el alumnado homosexual. Los y las docentes son agentes claves, sin embargo, son escasas las investigaciones que analizan e intervienen en el prejuicio sexual sutil de docentes hacia las personas homosexuales. El objetivo de este estudio es adaptar y aportar evidencias de validez y fiabilidad de la versión española de la Escala de Homonegatividad Moderna con docentes en formación.

Método. 772 docentes en formación inicial de la Universidad de Granada participan en un estudio con diseño instrumental. Ofrecen información de características sociodemográficas y responden tanto a la Escala de Homonegatividad Moderna, como dos escalas que miden el prejuicio hacia personas trans.
Resultados. La matriz de datos fue adecuada para el AFC con correcciones robustas por su alejamiento de la normalidad de las dos subescalas, se encontró un buen ajuste de los datos al modelo. El alpha de Cronbach, el índice de fiabilidad compuesta y de homogeneidad de los ítems arrojaron evidencias de buena consistencia interna. La VME mostró un valor adecuado y las correlaciones con constructos relacionados fueron positivas, significativas y menores que la raíz cuadrada de la VME.
Discusión y conclusiones. La versión española de la Escala de Homonegatividad Moderna permite medir el prejuicio sexual hacia personas homosexuales de docentes en formación y muestra más evidencias de validez para el modelo estructural de 11 indicadores que para el de 12 indicadores, con una adecuada consistencia interna y validez externa: convergente y discriminante.
<p>Applying the Dual Deficit Model: Do Students’ Test Preparation Strategies Moderate the Relationship between Test Anxiety and Students’ Academic Achievement?</p>
Authors: Nwosu Kingsley Chinaza , Onyemaechi Edeh Moses , Nkechi Ofojebe Edna , Cassim Hasina 
Published: September 2024

Introduction. Understanding the mechanism through which test anxiety impacts students’ learning outcomes is critical to its management. Test preparation strategies are associated with test confidence and could also affect students’ academic achievement. However, previous studies have underplayed the role students’ test preparation strategies could play in the associations between test anxiety and their academic achievement. Hence, the moderating roles of students’ test preparation strategies on the relationship between test anxiety and students' academic achievement were explained by framing our study within the dual deficit model.
Method. The cross-sectional research design was adopted, and 248 secondary school students constituted the sample.
Results. The major findings revealed significant negative relationships between the worry and the cognitive test anxiety subscales and students’ academic achievement scores. Furthermore, there was a joint significant negative relationship between the components of test anxiety and students’ academic achievement, whereas students’ test preparation strategies was not a significant moderator.
Discussion and Conclusion. Our findings indicate that learning strategies deficits may not significantly impact the effects of attentional-cognitive deficits on students’ academic achievement. It is concluded that cognitive-attentional deficit could defy strengths that may come from test preparation strategies.

Introducción. Este estudio busca evaluar psicométricamente las subescalas de inatención e hiperactividad/impulsividad de la Vanderbilt ADHD Teacher Rating Scale (VADTRS) para el diagnóstico del Trastorno por Déficit de Atención con Hiperactividad (TDAH) en niños y adolescentes en Chile.
Método. La muestra incluyó a 353 estudiantes de 2° de primaria a 3° de secundaria de tres escuelas en la provincia de Biobío, seleccionados mediante muestreo no probabilístico por conveniencia. La VADTRS es un cuestionario de observación conductual con 18 ítems que evalúan síntomas de inatención e hiperactividad/impulsividad. Se realizaron análisis estadísticos descriptivos, se evaluó la validez de contenido y se calculó la consistencia interna. Además, se llevó a cabo un análisis factorial confirmatorio para validar la estructura de la escala.
Resultados. Los resultados mostraron una alta concordancia inter-observador (v de Aiken = .96) y alta fiabilidad en la escala total (ω = .97) y subescalas de inatención (ω = .96) e hiperactividad/impulsividad (ω = .94). El análisis factorial confirmatorio validó la estructura de dos factores correspondientes a los síntomas del TDAH.
Discusión y conclusiones. La VADTRS demostró ser una herramienta confiable y válida para detectar el TDAH en estudiantes chilenos. Su fácil aplicación la convierte en una opción viable para identificar a quienes puedan enfrentar esta condición, permitiendo una intervención temprana y apoyo adecuado para mejorar su adaptación y desarrollo académico. La validación de esta escala es relevante, dado que la investigación sobre la detección del TDAH en Chile es limitada, y este estudio contribuye al campo de la salud mental infantil y adolescente. Implementar la VADTRS en el contexto educativo podría mejorar la detección temprana y proporcionar una atención más efectiva a aquellos estudiantes que presenten este trastorno, impactando positivamente en su bienestar y rendimiento académico. En conclusión, este estudio aporta conocimientos valiosos para la práctica clínica y la investigación en el área del TDAH en Chile.
Mechanical Shock Wave Suppression Structure in Hold-Down and Release Apparatus of Spacecraft

Published: September 2024

A lightweight and compact structural solution for mechanical shock suppression in spacecraft, such as the hold-down and release apparatus of satellites, is a critical and thorny issue. In this work, a ring-shaped structure is introduced to isolate mechanical waves within cylindrical shells. The underlying mechanism is that the ring-shaped structure undergoes different forms of deformation to counteract different modes of incident waves. A subwavelength Mn-Cu alloy ring is designed as a shock wave barrier in a typical spacecraft hold-down and release apparatus structure with multimodal wave excitation. We experimentally reveal that the Mn-Cu alloy ring reduces the peak value of the acceleration frequency response by 53.4% within a wide frequency range from 1 to 10 kHz. Meanwhile, in the time domain, the instantaneous acceleration peak can be weakened by 37.9%. This work provides a new strategy for shock control of shell structures in aerospace engineering and related fields.
Cytologic diagnosis and differential diagnosis of histiocytic signet ring cells in effusion specimens
Authors: Elahi Morvarid , Lam Hansen , Adams Christina , Li Qing Kay 
Published: September 2024

Objective:
Benign histiocytic proliferation in effusion specimens can be found in a variety of diseases such as rheumatoid arthritis, systemic lupus erythematosus, microorganism infections, trauma, reactive eosinophilic pleuritis, and others. In addition, nodular histiocytic/mesothelial hyperplasia is another well-recognized rare cause. The previous studies have shown that proliferative histiocytes have raisinoid nuclei and abundant eosinophilic granular cytoplasm and can be confused with malignant lesions, especially metastatic carcinomas. In this study, we evaluated the cytomorphology of benign histiocytes, discussed the diagnosis and differential diagnosis, and the clinical significance of histiocytic signet ring cells in effusion cytology.

Material and Methods:
Seven hundred and fifty-five benign effusion cases (433 pleural effusions and 322 abdominal fluids) were found over 1 year. Among benign cases, 35 cases (28 pleural effusions and seven abdominal fluids) were included with findings of dominantly histiocytic signet ring cell morphology as well as immunohistochemical (IHC) stains. The clinical findings were also correlated.

Results:
In contrast to the well-documented cytomorphology of raisinoid nuclei and eosinophilic cytoplasm of proliferative histiocytes in previous studies, we find that these cells predominately presented as signet ring cell morphology with clear cytoplasm. The most characteristic findings of benign histiocytes in pleural effusions are: (1) cells are arranged in sheets and/or scattered individual cells, but no two- or three-dimensional cell clusters; (2) cells are intermediate in size and with normal N/C ratio; (3) cells have eccentric located nuclei and abundant clear cytoplasm, giving signet ring cell appearance; (4) nuclei have fine granular chromatin pattern, no hyperchromia or coarse chromatin pattern, no nuclear atypia; and (5) immunohistochemical (IHC) stains demonstrate a strongly positivity for macrophage-histiocyte lineage marker CD68, but negativity for epithelial markers and mesothelial markers. Clinically, these patients do not demonstrate nodularity or lesions in the mesothelial lining of serous cavities.

Conclusion:
Our study provides a detailed characterization of benign histiocytic signet ring cells in effusion cytology. The differential diagnosis of histiocytic signet ring cells is broad. The most important differential diagnoses are metastatic adenocarcinoma and epithelioid signet ring cell mesothelioma. The accurate diagnosis is critical for the appropriate clinical management of the patient. Cytopathologists should be aware of the diagnostic pitfalls of benign histiocytic signet ring cells in effusion samples in daily practice.

The problem of using neural networks to select the optimal path of an autonomous transport object within the design of a control system for technical objects are discussed in the article. Static and dynamically obtained data about the operating environment are used. A method is proposed that allows one to take into account the restrictions on movement: terrain, probable static and dynamic obstacles - and choose the optimal path, taking into account the real dimensions of an autonomous object. An energy functional is proposed that ensures the achievement of a minimum of energy costs for movement under the condition of the safety of an autonomous object. A mathematical model has been built that meets the requirements of safety and optimal movement. The method allows you to find a solution in real time. A neural network providing the choice of a traffic area is presented. Examples of the algorithm’s operation for various operating conditions are given.

Гиперконвергенция (объединение ИТ-ресурсов в целостное решение с помощью типовых аппаратных блоков и программно определяемых устройств) стала одним из ведущих направлений в ИТ. В данной статье рассмотрено использование гиперконвергентных систем для виртуализации аппаратных средств, которые, в свою очередь, позволяют наиболее оптимальным образом распределять ресурсы вычислительных систем. Гиперконвергенция позволяет упростить управление IT-структурой: хранилищем, вычислениями, сетями, виртуализацией. Все эти задачи выполняются на одном оборудовании, что позволяет сократить время развертывания структуры, делает ее обслуживание более легким путем централизованного управления виртуальными средами через единый интерфейс и снижает трудоемкость рабочего процесса. Процессы приобретения, развертывания, поддержки и управления гиперконвергентной системой максимально оптимизированы, одним из главных ее преимуществ является простота масштабирования на основе блоков, за счет чего при необходимости система легко расширяется. В статье выполнен обзор системы виртуализации для обеспечения распределения ресурсов на основе гиперконвергентных решений, рассмотрены схемы работы такой системы, приведены примеры ее реализации.
Hyperconversion is the integration of information technology resources into a complete solution using standard hardware blocks and software-defi ned devices. hyperconversion has become one of the leading areas in IT. This article will discuss the use of hyperconverged systems for hardware virtualization, which will allow optimal allocation of computing resources. Hyper-convergence is used to simplify the management of the IT structure: storage, computing, networking, virtualization – all these tasks are performed on the same equipment, resulting in reduced deployment time of the structure and making it easier to maintain through centralized management of virtual environments through a single interface that will reduce the complexity of the workflow. The processes of acquiring, deploying and maintaining and managing a hyperconvergent system are optimized as much as possible, so one of the main advantages is simplicity of scaling based on blocks, and if necessary, the system can be easily expanded. The article will provide an overview of the virtualization system using hyperconverged solutions, consider the operation schemes, and provide examples of the system implementation.

Published: September 2024

Инерциальная навигация – это система, работающая на основе физических законов, существующих в пространстве независимо от деятельности человека. Обычно инерциальная навигационная система (ИНС) используется для определения положения, скорости и ориентации объекта, движущегося относительно поверхности Земли. Навигационная информация (положение, скорость и ориентация) беспилотного летательного аппарата (БПЛА) необходима для управления его полетом. Благодаря высокой устойчивости ИНС к препятствиям можно обеспечить надежный полет. В статье рассмотрены вопросы, такие как состав, принцип действия, устройство, преимущества и недостатки ИНС и указаны основные причины, обуславливающие важность использования этой системы. Кроме того, в статье предлагается модель инерциальной навигационной системы с оптимизированными параметрами для БПЛА, путем использования фильтра Калмана и внешних неинерциальных навигационных данных для повышения точности навигационной системы.
Inertial navigation is a system that works based on physical laws that exist in space, regardless of human activity. Typically, an inertial navigation system (INS) is used to determine the position, speed, and orientation of an object moving relative to the earth’s surface. The navigation information (position, speed and orientation) of an unmanned aerial vehicle (UAV) is needed to control its flight. Due to the high resistance of the INS to obstacles, a reliable flight can be ensured. The article discusses many issues, such as the composition, principle of operation, design, advantages and disadvantages of INS and indicates the main reasons for the importance of using this system. In addition, the article proposes a model of an inertial navigation system with optimized parameters for a UAV by determining methods for using the Kalman filter and external non-inertial navigation data to improve the accuracy of the navigation system data.
