Приведено обоснование использования метода главных компонент для оценки обобщённой характеристики дефекта при обработке многопараметровых акустических сигналов многократного зеркально-теневого метода контроля пруткового проката. Метод позволил сократить количество параметров сигналов при формировании критериев браковки, разработать методику оценки обобщённой характеристики дефекта, сформировать комплексный критерий браковки на основе недопустимого значения обобщённой характеристики дефекта для объектов из любых марок стали и любых диаметров. Результаты апробации предложенного подхода для оценки обобщённой характеристики естественных дефектов с использованием полученной регрессионной зависимости удовлетворительно согласуются с результатами металлографических исследований.
The paper provides a justification for the use of the principal component method for assessing the generalized characteristics of the defect in the processing of multi-parameter acoustic signals of the mirror-shadow multiple reflections method of bar stock testing. The method allows reducing the number of signal parameters in the formation of rejection criteria, developing a methodology for assessing the generalized characteristics of the defect, and forming a complex rejection criterion based on the unacceptable value of the generalized defect characteristic for objects made of any steel grades and of any diameters. The results of approbation of the proposed approach for evaluation of the generalized characteristic of natural defects using the regression dependence produced are satisfactorily consistent with the results of metallographic studies.

Теоретически исследован новый метод генерации лазерного излучения без инверсии населённостей в «красном» крыле D1-линии атомов щелочных металлов при резонансном поглощении широкополосного излучения лазерных диодов накачки на переходе D1. Причиной возникновения лазерной генерации является то обстоятельство, что в красном крыле спектральной линии вероятность вынужденного испускания превышает вероятность поглощения, если однородное уширение из-за взаимодействия активных частиц с буферным газом существенно превышает естественное (при больших давлениях буферного газа). Получены аналитические формулы, представляющие работу лазера на парах щелочных металлов при поперечной диодной накачке. Выяснено, что наиболее перспективным объектом для наблюдения лазерной генерации без инверсии населённостей в красном крыле D1-линии атомов щелочных металлов являются атомы цезия. В достаточно длинной активной среде (длина среды в 50 раз превышает её ширину) эффективность преобразования излучения накачки в лазерное излучение может достигать 57 % при давлении буферного газа 5 атм, интенсивности излучения диодов накачки 5 кВт/см2 и полуширине его спектра 1 см-1. Частота лазерного излучения может перестраиваться на несколько десятков см-1.
A new method for generating laser radiation without population inversion in the «red» wing of the D1 line of alkali metal atoms under resonant absorption of broadband radiation from pump laser diodes at the D1 transition has been theoretically investigated. The reason for the occurrence of laser generation is the fact that the probability of stimulated emission in the red wing of the spectral line exceeds the probability of absorption if the uniform broadening due to the interaction of active particles with the buffer gas significantly exceeds the natural one (at high pressures of the buffer gas). Analytical formulas that describe the operation of an alkali metal vapor laser under transverse diode pumping are derived. It has been found that the most promising objects for observing laser lasing without population inversion in the red wing of the D1 line of alkali metal atoms are cesium atoms. In a sufficiently long active medium (the length of the medium is 50 times greater than its width), the conversion efficiency of pump radiation into laser radiation can reach 57% at a buffer gas pressure of 5 atm, a pump diode radiation intensity of 5 kW/cm2, and a half-width of its spectrum of 1 cm-1. The frequency of laser radiation can be tuned by several tens of cm-1.

Published: September 2024

BACKGROUND
Clinical decision support (CDS) systems offer the potential to improve pediatric care through enhanced test ordering, prescribing, and standardization of care. Its augmentation with artificial intelligence (AI-CDS) may help address current limitations with CDS implementation regarding alarm fatigue and accuracy of recommendations. We sought to evaluate strengths and perceptions of CDS, with a focus on AI-CDS, through semistructured interviews of clinician partners.

METHODS
We conducted a qualitative study using semistructured interviews of physicians, nurse practitioners, and nurses at a single quaternary-care pediatric emergency department to evaluate clinician perceptions of CDS and AI-CDS. We used reflexive thematic analysis to identify themes and purposive sampling to complete recruitment with the goal of reaching theoretical sufficiency.

RESULTS
We interviewed 20 clinicians. Participants demonstrated a variable understanding of CDS and AI, with some lacking a clear definition. Most recognized the potential benefits of AI-CDS in clinical contexts, such as data summarization and interpretation. Identified themes included the potential of AI-CDS to improve diagnostic accuracy, standardize care, and improve efficiency, while also providing educational benefits to clinicians. Participants raised concerns about the ability of AI-based tools to appreciate nuanced pediatric care, accurately interpret data, and about tensions between AI recommendations and clinician autonomy.

CONCLUSIONS
AI-CDS tools have a promising role in pediatric emergency medicine but require careful integration to address clinicians' concerns about autonomy, nuance recognition, and interpretability. A collaborative approach to development and implementation, informed by clinicians’ insights and perspectives, will be pivotal for their successful adoption and efficacy in improving patient care.

Authors: Kairiené Aida , Mažeikienė Natalija 
Published: September 2024

Aim. This article presents the research on using cartography as a research method based on Gilles Deleuze and Félix Guattari’s (2004) insights. The aim of the study – to unfold and visualise students' learning experiences in non-formal and informal learning contexts beyond the classroom.
Methods. Cartography and rhizoanalysis. Cartography is a method of mapping (Wilmott, 2020). In order to create rhizomatic maps we used Deleuze and Guattari (2004) theoretical insights. The rhizoanalysis (Masny, 2015) was carried out according to Deleuze and Guattari’s (2004) rhizome principles: connectivity and heterogeneity multiplicity and rupture, cartography and decalcomania. The rhizoanalysis simultaneously reveals Alecia Youngblood Jackson and Lisa Mazzei's (2012) process of "thinking with theory". Thirty-eight students from upper-grade classes participated in this research. Each student’s learning path was depicted as their rhizomatic journeys, using various concepts such as nomads, lines of flight, becoming.
Results. The rhizoanalysis makes it possible to reveal students’ rhizomatic learning experiences, areas of interest and learning styles. Such a map challenges an existing hierarchical framework and conveys how students’ freely make connections through lines of flight and create their own learning paths.
Conclusions. This study demonstrates cartography as a useful methodology for visualising students’ learning experiences. Also, this study is unique and distinctive because it reveals the nomadic trajectories of individual learners and offers a thorough investigation of their activity destinations. The researchers of this study advise that students' non-formal and informal learning experiences be included into their formal education by using nomadic pedagogy.

Published: September 2024

Nos últimos cinquenta anos, a informática tem sido gradualmente integrada ao sistema educacional brasileiro. Essa integração passou por várias fases e programas, cada um com suas metas e desafios. Desde o Decreto nº 84.067 em 1979, que instituiu a Política Nacional de Informática, até a criação do ProInfo em 1997 e a Política de Inovação Educação Conectada (PIEC) em 2023, houve progressos significativos, mas também dificuldades na implementação eficaz dessas políticas. Este estudo busca compreender em um contexto histórico as políticas públicas voltadas para a informática, explorando a sua evolução no âmbito da educação brasileira, e destacando iniciativas e programas que moldaram a inserção de tecnologias digitais no ensino. Para a construção deste artigo, foi adotada uma abordagem qualitativa, com pesquisa bibliográfica. Com esse histórico, foi possível construir uma linha do tempo interativa que apresenta as políticas públicas concebidas no Brasil para a informatização das escolas e formação de professores, culminando no ensino da computação, proposto atualmente para as escolas de educação básica brasileiras, na Base Nacional Comum Curricular e seu Complemento.

Published: September 2024

ABSTRACT
Robust estimation of moment magnitude (Mw) can be challenging for Iraq due to the strong lateral heterogeneity across diverse tectonic zones. We aim to improve moment magnitude estimation by investigating the reliability of using a 1D coda envelope model in diverse tectonic zones of different lateral effects and offer a way forward for reliable estimates of Mw for small events that are difficult to waveform model. Iraq comprises two main tectonic zones: (1) the Outer platform, consisting of the northwestern Zagros fold-thrust belt and the Mesopotamian foredeep, and (2) the Inner Arabian platform which is overlain by the Iraqi desert. A simple 1D coda envelope model was used because coda waves have a low sensitivity to the source and path heterogeneity. Three separate coda calibrations were conducted to investigate the robustness of a single 1D calibration to fit the country: Whole-region calibration, Zagros calibration, and Mesopotamia calibration. In the whole-region calibration, we used stations from both the Zagros and Mesopotamia zones. In the two other calibration models, we used only stations that were in those particular zones. Ground-truth reference spectra derived from the coda spectral ratio method were used to constrain high-frequency site terms. There was no drastic difference when comparing the moment magnitudes calculated from the waveform modeling and the three calibration models. The results show that the 1D coda envelope model is a reliable method even for a region with diverse tectonic zones. Hence, we recommend using the whole-region calibration model for moment magnitude estimation that provides more complete path coverage and avoids biases introduced by path correction failures. The proposed calibration is a fundamental step in updating the comprehensive earthquake catalog and probabilistic seismic hazard assessments for Iraq.

Background: Aim was to assess the audiological function in children with autism spectrum disorder (ASD).
Methods: A prospective study conducted over one year at a tertiary care center involved 55 children: 30 with ASD (Group A) and 25 healthy children (Group B). Tympanometry, transient evoked otoacoustic emissions (TEOAE), and brainstem evoked response audiometry (BERA) tests were performed on both groups and compared.
Results: The study involved 55 children divided in 2 groups-ASD (Group A) and healthy children (Group B). Tympanometry showed Type 'A' curves in all group B children and in 26 out of 30 group A children; 4 children in group A with type 'B' or 'C' curves were excluded. In group A, 16.6% of children had TEOAE response in one ear, and 20% had no responses. All children in group B had TEOAE responses in both ears. BERA results showed significant differences between both groups in terms of inter-peak latencies between waves I and III and III and V (p<0.05), though the inter peak latency between waves I and V was not significant (p>0.05).
Conclusions: According to our study, patients with ASD in addition to neurological and behavioral assessment need regular auditory function testing as well.

Is vitamin D deficiency a risk factor in the occurrence and recurrence of febrile convulsions in children?
Authors: Thoppil Joanne , Jyothirmayi Chinta Annie , Arockiyaraj Magdalenal , Mathew Leni G. , Rebekkah Grace , Mathai Sarah 
Published: September 2024

Background: Febrile seizure (FS) is the commonest childhood seizure. Our aim was to evaluate low Serum 25(OH) vitamin D level (vitamin D) as a risk factor for FS and whether vitamin D supplementation reduces its recurrence.
Methods: A prospective cohort of children aged 6-60 months with FS (cases) and children with fever ≤3 days without seizures (controls) were recruited over a 2-year period. Vitamin D level was measured; those with low levels (<20 ng/ml) were treated with vitamin D for 3 months. Telephonic follow up was done upto 3 months regarding compliance, thereafter, upto 24 months for seizure recurrence.
Results: 259 children (125 cases,134 controls) were recruited. Overall, 90 children (34.7%) had low vitamin D level. There was no difference between cases and controls with low vitamin D levels (p=0.37). 22 (17.6%) children had seizure recurrence. Of this serum vitamin D level was low in 2 (9.1%) while 20 (90.9%) had sufficient levels (p=0.021). The odds ratio for FS recurrence was 5.8 times higher among cases with normal vitamin D level (>20 ng/ml).
Conclusions: There was no difference in mean vitamin D levels between cases and controls. However, there was significantly lower seizure recurrence in children who had low vitamin D level at presentation and had received vitamin D therapy. We postulate that treatment with vitamin D may reduce risk of FS recurrence even in those with serum vitamin D level in the “sufficient” range as per the recommended guidelines. Larger RCTs are needed to confirm these findings.
