Published: October 2024

Використання інформаційно-комунікаційних технологій в освіті становить відносно досліджене явище попри те, що воно не було центром уваги дослідників до початку XXI ст. Педагоги та дослідники вивчають проблеми використання інформаційно-комунікаційних технологій у контексті знаходження нових способів інтеграції таких технологій у навчальну діяльність. Однак, усупереч дослідженості інформаційно-комунікаційних технологій постають усе нові й нові питання, пов’язані з постійним розвитком галузі. Мету поданої розвідки становить висвітлення досвіду розробки й тестування додатків, як основного виду діяльності протягом навчальної практики «Інформаційно-комунікаційні технології в школі» у студентів-педагогів. Це уможливлює виявлення типів інформаційно-комунікаційних завдань. Методи. Досягнення поставленої мети передбачає послуговування такими теоретичними методами дослідження, як аналіз, систематизація й узагальнення використаних у розвідці джерел, синтез та інтерпретація отриманої інформації. У розвідці інтерактивні завдання класифіковано на три типи: пояснювальні, тренувальні вправи та завдання для перевірки набутих компетенцій. Досвід проведення навчальної практики «Інформаційно-комунікаційні технології в школі» доводить беззаперечну необхідність подібної діяльності, що ознайомлюватиме студентів-педагогів із технічними аспектами викладання та планування уроків. Збір зворотнього зв’язку демонструє щире зацікавлення такими сферами роботи. Студенти діляться досвідом відкриття для себе різних нових підходів до розробки завдань, додатків, які покращують роботу з матеріалом тощо. Педагог, який пройшов таку практику впевненіше почуватиметься не лише під час роботи з інформаційно-комунікаційними технологіями на заняттях у закладі середньої освіти, але й упродовж формування власного спецкурсу, викладання в дистанційному та змішаному форматах.

Authors: Datt Shyama , Datt Thakur , Singh N.P
Published: October 2024

Background: Over the past few decades, cases of dermatophytosis have been on the rise. Recently, the introduction of newer, less toxic antifungal drugs has improved treatment options. However, the prolonged use of antifungals has led to the emergence of acquired resistance among strains that were previously susceptible, as well as an increase in infections caused by less common species. This scenario underscores the growing need for rapid and accurate antifungal susceptibility testing methods. In this study, antifungal susceptibility was assessed using the in-vitro micro broth dilution method, adhering to the CLSI M38-A guidelines
Methods: 60 clinical specimens were collected from Nail and skin of the patients of dermatophytosis from Delhi (India). Minimal inhibitory concentration (MIC) was performed in microtiter plates with U-bottom and incubated at 35° C. Reading were taken after 48 & 96 hrs of incubation for Trichophyton mentagrophytes and Trichophyton rubrum, against 5 antifungal drugs namely fluconazole, itraconazole (triazoles), griseofulvin, terbinafine and Luliconazole.
Results: Most of the dermatophytes had uniform patterns of susceptibility to the antifungal agents tested. Low MIC values as 0.03μg/mL were found for 33.3%, 31.6% and 15% of isolates for itraconazole and terbinafine, respectively.
Conclusion: In conclusion, it may be useful to undertake periodical screening programs to detect the antifungal susceptibility of newer antifungal agents.
Explaining the Correlates of Child Mortality and Under-5 Survival in Nigeria
Authors: Molelekoa Thonaeng Charity , Oyekale Abayomi Samuel
Published: October 2024

Background: Survival of children under-5 is among the foremost public health concerns that has been pursued in the Sustainable Development Goals (SDGs). A proper understanding of the correlates of child survival is of paramount relevance to health policy formulation and development of interventions to promote child's health outcomes. This study therefore analysed the determinants of the number of recorded child mortality and survival in Nigeria.
Subject and Methods: The data were the Malaria Indicator Survey (MIS) that were collected in Nigeria in 2021. The samples were drawn with multi-stage sampling method following the 2023 Population and Housing Census sampling frame. A total of 14185 housing units were randomly selected of which 13887 were occupied and 13727 were successfully interviewed. In each household, all women belonging to the reproductive ages of 15-49 years were interviewed. A total of 14647 women were eligible, of which 14476 were successfully interviewed (Demographic and Health Survey (DHS), 2021). The data were analyzed using the Negative Binomial regression and logistic regression models.
Results: The logs of the number of dead children were significantly higher (p<0.05) for mothers from North West and North East Nigeria, while children from these regions also had a significantly lower probability of surviving. The mothers from urban areas had significantly lower log of dead children while urban children had significantly higher probability of surviving. Mothers with secondary and tertiary education had significantly lower log of dead children, while birth in the past five years and total children born reduced child’s survival. Twin children also had a significantly lower probability of surviving while mother’s maturity promoted child’s survival.
Conclusion: Promotion of child survival in Nigeria requires a concerted effort that disaggregates interventions across Nigerian zones with preferences for those in the north and rural dwellers. In addition, there is the need to promote interventions to assist women with multiple births, promote girl child education and discourage teenage pregnancies.
Wzrost gospodarczy Japonii : od restauracji Meiji do Abenomics
Authors: Tomeczek Artur F.
Published: October 2024

Aby zrozumieć niezwykle skomplikowaną sytuację ekonomiczną współczesnej Japonii, niezbędne jest poznanie trudnej historii tego kraju. Restauracja Meiji stanowiła rewolucją w japońskim społeczeństwie i gospodarce. W jej wyniku Japonia przekształciła się z państwa quasi-feudalnego w globalną potęgę ekonomiczną. Industrializacja Japonii wraz ze znaczeniem, jakie miała dla całej Azji, znalazły odzwierciedlenie w teorii klucza lecących gęsi K. Akamatsu. Japończycy nadzwyczaj umiejętnie zaadaptowali najlepsze instytucje krajów zachodnich, jednocześnie zachowując swoją niepowtarzalną tożsamość. Restauracja Meiji stanowi inspirację dla twórców współczesnych reform gospodarczych, które mogą wyprowadzić Japonię z wieloletniej stagnacji. Tak zwane trzy strzały Abenomics to reformy monetarne, fiskalne i strukturalne, których najważniejszym i najbardziej kontrowersyjnym elementem są rewolucyjne zmiany polityki monetarnej wprowadzane przez Bank Japonii. Głównym celem badawczym autora niniejszej pracy była identyfikacja czynników i barier wzrostu gospodarczego w Japonii ze szczególnym uwzględnieniem przyczyn długookresowej stagnacji gospodarczej po 1989 r. Przeprowadzona analiza japońskiej gospodarki dotycząca bardzo długiego okresu (1868–2018) pozwoli na głębsze zrozumienie przyczyn zarówno powojennego cudu gospodarczego, jak i okresu zwanego „straconymi dekadami”. Ewolucja gospodarki Japonii została przedstawiona na podstawie analizy źródeł historycznych, japońskich i międzynarodowych baz danych oraz najważniejszych pozycji w literaturze przedmiotu dotyczących wzrostu gospodarczego, polityki ekonomicznej i stagnacji sekularnej. Niniejsza praca stanowi atrakcyjną propozycję z perspektywy nauk ekonomicznych, politycznych i historycznych szczególnie dla osób zainteresowanych tematyką Japonii.

Published: October 2024

Objective: This study aimed to explore corneal curvature changes following strabismus surgery using a quadric surface fitting model to address ocular misalignment.
Material and Methods: In this prospective cross-sectional study, 54 completed cases (84 eyes) of patients aged 6–60 years old (mean 10 years old) undergoing horizontal rectus muscle surgery were examined using placido-based keratometry with the Oculus Keratograph 5M system. Data on corneal curvature were collected one week pre-operation, and again one week, one month, and three months post-operation. Asphericity in the vertical meridian (Qy) and horizontal meridian (Qx), and surgical-induced astigmatism (SIA) were calculated.
Results: The 84 eyes included were categorized into three groups: horizontal muscle surgeries, oblique muscle surgery, and combined horizontal and oblique muscle surgeries. Significant corneal prolation (steep central, flat peripheral) was revealed in the vertical meridian (Qy) at 3 months postoperatively for lateral rectus (LR) recession in the first group (p < 0.001), and the mean SIA was 0.45 D (95% CI: 0.35–0.56 D). A similar effect was seen in the vertical meridian of the third group (p < 0.01), with a mean SIA at 3 months of 0.27 D (95% CI: 0.23–0.32 D).
Conclusion: Lateral rectus muscle recession induces corneal vertical prolation for up to 3 months post-operation. Surgeons are thus advised to re-evaluate refraction and defer contact lens refitting, refractive surgery, and intraocular lens calculations for at least 3 months after the procedure.

Objective: To evaluate the effectiveness of a low-vision service by using three tools and to identify the specific outcomes obtained from each instrument.
Materials and Methods: Patients consecutively visiting the low-vision clinic at Siriraj Hospital, Bangkok, Thailand, were enrolled. The impact of the prescribed rehabilitation on patient quality of life was measured using three tools: the Low-Vision Quality-Of-Life Questionnaire (LVQOL); the generic EuroQol Five-Dimensional Questionnaire (EQ-5D); and the World Health Organization International Classification of Functioning, Disability, and Health (WHO-ICF).
Results: Out of the 104 patients recruited, 76 patients (mean age, 53 ± 16.2 years) completed the questionnaires before and after rehabilitation, which was assessed after 5.8 ± 2.0 months. Post-rehabilitation, the time of follow-up, patients had significant improvements in the mean scores of both the LVQOL scores and mean EQ-5D scores compared to before rehabilitation (P < 0.001), with Cohen’s effect sizes of 0.85 and 0.67, respectively. Subgroup analyses by age, severity, and cause of visual impairment also showed significant improvements in the LVQOL (P < 0.05), but not the EQ-5D score in the blindness severity subgroup. The ICF scores also showed significant improvement in most domains, including seeing functions, mobility across different locations, transportation use, meal preparation, economic self-sufficiency, community life, and recreational activities (P < 0.01).
Conclusion: Patients with low vision experienced significant improvements following vision rehabilitation, especially in terms of seeing functions and mobility. Evaluation by different questionnaire types could provide additional information. The WHO-ICF was effective in assessing each domain related to activity performance and participation.

A dinâmica laborativa do crowdsourcing on-line análoga ao trabalho escravo: uma análise sobre as atividades laborativas por meio das plataformas digitais
Authors: Mol Lucas Alves , Franco Ângela Barbosa
Published: October 2024

O estudo desvela como problema de pesquisa a oferta de serviços humanos, por meio de plataformas virtuais, em condições análogas ao trabalho escravo. Parte-se da hipótese de que ante a concorrência global, o trabalho intermediado pelas plataformas virtuais favorece a implementação de péssimas condições de trabalho e de jornadas exorbitantes em troca de uma retribuição pecuniária aviltante. O desrespeito às garantias clássicas de um trabalho digno é corroborado pela ausência de uma norma específica sobre o tema, bem como pelas recentes divergências jurisprudenciais, as quais apenas dificultam o resguardo de direitos dados como básicos de todo trabalhador. Assim, a partir de um estudo interdisciplinar do tipo jurídico-interpretativo, com espeque em dados secundários, a investigação ampara-se em um raciocínio dedutivo para destacar os preceitos constitucionais e trabalhistas capazes de fundamentar as precariedades dos trabalhos intermediados por plataformas virtuais. Nesse contexto, registra-se uma evidente semelhança do crowdsourcing on-line com o trabalho análogo ao de escravo.

To the best of our knowledge, we employ laser-induced breakdown spectroscopy (LIBS) to simultaneously measure multiple properties (pressure, equivalence ratio, and H2 ratio) of product gas under turbulent flow and highenthalpy conditions for the first time. We also introduce an improved LIBS signal acquisition configuration that enhances signal-to-noise ratio (SNR) and shot-to-shot stability. Under varying operating conditions (pressure: 3 to 15 bar, equivalence ratio: 0.7 to 1.2 and hydrogen enriched ratio: up to 50% by volume), the laser is focused at downstream of the multi-nozzle burner where combustion product gas flows turbulently. Laser-induced plasma (LIP) is generated and plasma spectra are simultaneously measured in both right-angle and backward directions. The Proper Orthogonal Decomposition (POD) and Gaussian Process Regression (GPR) model are employed to estimate multiple properties of product gas that exhibit non-linear correlations. POD extracts the principal features from the spectra and GPR model quantifies these properties. The results demonstrate that the proposed model achieves the highest prediction accuracy for pressure, hydrogen concentration, and equivalence ratio, with the average relative errors of model prediction (REP) values of 0.93%, 8.3%, and 1.45%, respectively. Furthermore, measurement in the backward direction yields a more stable and stronger signal intensity compared to those in the right-angle direction measurement. Specifically, the former successfully captures plasma spectra at 15 bar, whereas the latter fails to do so. This study significantly contributes to the precise measurement of combustion product gas in harsh high-enthalpy environments. Our approach provides important information for the design and optimization of combustion-related facilities and indicates promising applicability of LIBS in various other environments.

The confirmed benefits of tandem blades in terms of large flow turning angle, low flow losses and wide working range make them more competitive than conventional blades when applied in the rear stator of the multistage axial-flow compressor. However, the knowledge of complex correlations between three-dimensional (3D) tandem blade designs and compressor aerodynamic performance at design and off-design points have not been fully discovered so far. Thus, an explainable data mining framework integrating extreme gradient boosting (XGBoost) meta-model with Shapley additive explanations (SHAP) is proposed and implemented to the rear tandem-bladed stage of an F-class heavy-duty gas turbine compressor. This study involves both local explanation of feature importance as well as the identification of favorable variation directions for design parameters in terms of 2D meridional pre-diffuser, 3D blade sweep and bow, and tandem blade configuration parameters, which enable to extract priori design recommendations. The present work is beneficial for the development of three-dimensional design optimization of advanced tandem-bladed rear stage of compressors.

Aim: It is known that oral health is an integral part of general health and oral health is closely related to quality of life. This study aimed to evaluate the relationship between oral health-related quality of life, malnutrition and other oral health problems.

Methods: A sociodemographic form consisting of 25 questions was applied. The Oral Health Impact Profile and Oral Health-Related Quality of Life scales were used to assess oral and dental health and the Mini-Nutritional Assessment Test to assess nutritional status. T-test and Chi-Square test were used to determine whether there was a difference between the variables and their significance levels.

Results: The mean age of 300 people who participated was 64.90±15.38 years. It was determined that there was no statistically significant relationship between the Mini-Nutritional Assessment Test and Oral Health Impact Profile and Oral Health-Related Quality of Life Scale (p=0.763, p=0.429). 80% of the patients receiving home care stated that they needed oral health services. 98.3% of the patients stated that their family physicians did not make any recommendations for oral health.

Conclusion: We did not detect any relationship between the Oral Health Impact Profile and Oral Health-Related Quality of Life Scale and Mini-Nutritional Assessment in our study. In addition, poor oral health and malnutrition were found to be high in fully and semi-dependent individuals. There is a need for studies with different methods involving larger populations in this regard.

Authors: Shahinaj Rozeta , Hasanbelli Brunilda , Nurce Alma , Qirici Orieta
Published: October 2024

Aim: This study aims to investigate if fetal growth restriction in pregnant women with pre-eclampsia can predict adverse pregnancy and neonatal outcomes.

Methods: A retrospective study was conducted. The study population included pregnant women diagnosed with pre-eclampsia who gave birth at the University Hospital of Obstetrics and Gynecology "Queen Geraldine" of Tirana from January to December 2023. They were categorized into two groups: the group of pre-eclampsia associated with fetal growth restriction and the group of preeclampsia without fetal growth restriction. Data were collected from the medical records and were analyzed for obstetrical and neonatal outcomes using IBM SPSS Statistics for Windows version 27.

Results: The sample included 189 pregnant women, The group of patients of preeclampsia associated with FGR (46 cases) had significantly lower gestational age at delivery (35.54 vs. 37.18 weeks), lower birth weights (1919.5 vs. 3053g.), more perinatal deaths (12.90% vs. 2.27%), more stillbirths (32.60% vs. 7.69%), more preterm births before 34 weeks (41.30% vs. 20.27%), more cesarean deliveries (65.21% vs. 46.85%), more patients with HELLP syndrome (13.04% vs. 3.49%), more neonates with Apgar scores

Conclusions: This study highlights the significant impact of fetal growth restriction on maternal and neonatal outcomes in pregnancies complicated by pre-eclampsia. Our analysis shows that fetal growth restriction in patients with pre-eclampsia could predict worse pregnancy outcomes. The prevention, detection, and treatment of fetal growth restriction might have important positive reflections on public health.

Published: October 2024

Numerical models of crop response to irrigation and weather forecasts with internet access should be fully utilized in modern irrigation management. In this respect, we developed a new numerical scheme to optimize irrigation depth that maximizes net income over each irrigation interval. The scheme applies volumetric water prices to inspire farmers to save water, and it provides growers with real-time estimates of irrigation depth and net income over the growing season. To evaluate this scheme, we carried out a field experiment for groundnut (Arachis hypogaea L.) grown in a sandy field of the Arid Land Research Center (ALRC), Tottori University, Japan. Two treatments were established to compare the net income of the proposed scheme with that of an automated irrigation system. Results showed that although the proposed scheme gave a larger amount of seasonal irrigation water 28%, it achieved 2.18 times of net income owing to 51% higher yield compared to results of the automated irrigation system. The accuracy of rainfall forecast had little effect on the scheme outputs, where the root mean square error (RMSE) between observed and forecasted rainfall was 4.63 mm. By utilizing numerical simulation information of the soil–plant–atmosphere system into the proposed scheme, it would be a more cost-effective tool for optimizing irrigation depths than automated irrigation systems.

Published: October 2024

Background

Omalizumab (OMA) was the first FDA-approved biological drug for severe chronic spontaneous urticaria (CSU), and until today is the only beneficial and truly safe one. The objectives were: To assess the prevalence of CSU patients in whom OMA cannot be stopped over time. We also asked if biomarkers (e.g., anti-TPO antibodies and total IgE) could assist in anticipating this issue.

Methods

We used our prospective registry of 93 patients, which included CSU disease duration, the onset of OMA treatment, Urticaria Activity Score (UAS7) during follow-up, co-morbidities, serum IgE levels and the presence of anti-TPO antibodies. Finally, we assessed the response to OMA during a period of six years.

Results

Out of the 93 treated CSU patients, OMA was stopped in ten patients after six months being defined as failures. In another ten patients, OMA was discontinued after 2–4 years of therapy, achieving a remission. Seventy-three patients are still treated between 2 and 6 years, having different degrees of response. Of these, in thirty-eight (52%) patients, we could not stop OMA even after six years due to CSU relapses. The prevalence of lower serum IgE levels and anti-TPO antibody positivity was significantly higher in CSU patients in whom OMA could not be stopped.

Conclusion

This is the first study where OMA-treated CSU patients were followed up to six years. In half of them, long-term therapy of six years is still required.
Variational Bayes latent class analysis for EHR-based phenotyping with large real-world data
Authors: Buckley Brian , O'Hagan Adrian , Galligan Marie
Published: October 2024

Introduction

Bayesian approaches to patient phenotyping in clinical observational studies have been limited by the computational challenges associated with applying the Markov Chain Monte Carlo (MCMC) approach to real-world data. Approximate Bayesian inference via optimization of the variational evidence lower bound, variational Bayes (VB), has been successfully demonstrated for other applications.

Methods

We investigate the performance and characteristics of currently available VB and MCMC software to explore the practicability of available approaches and provide guidance for clinical practitioners. Two case studies are used to fully explore the methods covering a variety of real-world data. First, we use the publicly available Pima Indian diabetes data to comprehensively compare VB implementations of logistic regression. Second, a large real-world data set, Optum™ EHR with approximately one million diabetes patients extended the analysis to large, highly unbalanced data containing discrete and continuous variables. A Bayesian patient phenotyping composite model incorporating latent class analysis (LCA) and regression was implemented with the second case study.

Results

We find that several data characteristics common in clinical data, such as sparsity, significantly affect the posterior accuracy of automatic VB methods compared with conditionally conjugate mean-field methods. We find that for both models, automatic VB approaches require more effort and technical knowledge to set up for accurate posterior estimation and are very sensitive to stopping time compared with closed-form VB methods.

Discussion

Our results indicate that the patient phenotyping composite Bayes model is more easily usable for real-world studies if Monte Carlo is replaced with VB. It can potentially become a uniquely useful tool for decision support, especially for rare diseases where gold-standard biomarker data are sparse but prior knowledge can be used to assist model diagnosis and may suggest when biomarker tests are warranted.
(In)stability of de Sitter quasinormal mode spectra
Authors: Warnick C. M.
Published: October 2024

We consider how the quasinormal spectrum for the conformal wave operator on the static patch of de Sitter changes in response to the addition of a small potential. Since the quasinormal modes and co-modes are explicitly known, we are able to give explicit formulae for the instantaneous rate of change of each frequency in terms of the perturbing potential. We verify these exact computations numerically using a novel technique extending the spectral hyperboloidal approach of Jaramillo et al. (2021). We propose a definition for a family of pseudospectra that we show capture the instability properties of the quasinormal frequencies.

Background

The SCI-GDI is an accurate and effective metric to summarize gait kinematics in adults with SCI. It is usually computed with the information registered with a photogrammetry system because it requires accurate information of pelvic and hip movement in the three anatomic planes, which is hard to record with simpler systems. Additionally, due to being developed from the GDI, the SCI-GDI is built upon nine joint movements selected for a pediatric population with cerebral palsy, for which the GDI was originally developed, but those nine movements are not necessarily as meaningful for adults with SCI. Nevertheless, pelvic movement and hip rotation have been proven to have low reliability even when acquired with gold-standard photogrammetry systems. Additionally, the use of photogrammetry is limited in real-life scenarios and when used with rehabilitation technologies, which limits the use of the SCI-GDI to evaluate gait in alternative scenarios to gait laboratories and to evaluate technologies for gait assistance. This research aimed to improve the SCI-GDI to broaden its applicability beyond the use of photogrammetry.

Methods

An exploration of the mathematical relevance of each joint movement included in the original GDI for the performance of the metric is performed. Considering the results obtained and the clinical relevance of each of the 9 joints used to compute the SCI-GDI in the gait pattern of the SCI population, a more adaptable SCI-GDI is proposed using four joint movements that can be precisely captured with simpler systems than photogrammetry: sagittal planes of hip, knee and ankle and hip abduction/adduction.

Results

The reduced SCI-GDI (rSCI-GDI) effectively represents gait variability of adults with SCI as does the SCI-GDI, while providing more generalizable results and equivalent or stronger correlations with clinical tests validated in the population. During the derivation of the improved index, it was demonstrated that pelvic movements, hip rotation, and foot progression angle introduce high variability to the dataset of gait patterns of the adult population with SCI, but they have low relevance to characterize gait kinematics of this population. The rSCI-GDI can be calculated using the 14-feature vectorial basis included in the electronic addendum provided.

Published: October 2024

Our previous article entitled “Proteomics and its applications in breast cancer”, proposed a Breast Cancer Continuum Concept (BCCC), including a Breast Cancer Cell Continuum Concept as well as a Breast Cancer Proteomic Continuum Concept. Breast cancer-on-chip (BCoC), breast cancer liquid biopsy-on-chip (BCLBoC), and breast cancer metastasis-on-chip (BCMoC) models successfully recapitulate and reproduce in vitro the principal mechanisms and events involved in BCCC. Thus, BCoC, BCLBoC, and BCMoC platforms allow for multiple cell lines co-cultivation to reproduce BC hallmark features, recapitulating cell proliferation, cell-to-cell communication, BC cell-stromal crosstalk and stromal activation, effects of local microenvironmental conditions on BC progression, invasion/epithelial-mesenchymal transition (EMT)/migration, intravasation, dissemination through blood and lymphatic circulation, extravasation, distant tissues colonization, and immune escape of cancer cells. Moreover, tumor-on-chip platforms are used for studying the efficacy and toxicity of chemotherapeutic drugs/nano-drugs or nutraceuticals. Therefore, the aim of this review is to summarize and analyse the main bio-medical roles of on-chip platforms that can be used as powerful tools to study the metastatic cascade in BC. As future direction, integration of tumor-on-chip platforms and proteomics-based specific approaches can offer important cues about molecular profile of the metastatic cascade, alowing for novel biomarker discovery. Novel microfluidics-based platforms integrating specific proteomic landscape of human milk, urine, and saliva could be useful for early and non-invasive BC detection. Also, risk-on-chip models may improve BC risk assessment and prevention based on the identification of biomarkers of risk. Moreover, multi-organ-on-chip systems integrating patient-derived BC cells and patient-derived scaffolds have a great potential to study BC at integrative level, due to the systemic nature of BC, for personalized and precision medicine. We also emphasized the strengths and weaknesses of BCoC and BCMoC platforms.
