Authors: Türk Hakan , Arslan Erkan , Ün Sıtkı , Karabıçak Mustafa , Tongal Arda
Published: December 2024

Background: In rare cases, the catheter balloon cannot be deflated during catheter removal or repla-cement. In this study, we aimed to create a treatment algorithm for patients whose catheter balloon could not be deflated and to evaluate the effectiveness of a newly applied method.
Materials and Methods: 55 male patients who applied to our clinic between January 2020 and July 2023 because the foley catheter could not be removed were evaluated. The methods applied in line with the algorithm we applied in our clinic were evaluated in terms of complications. However, a new met-hod that has not been described before in the literature was evaluated in terms of complications and effectiveness
Results: A total of 55 patients were included in the study. The average age of the patients was 73.8 years. The average foley catheter stay was 14.9±8 days. When we examine the reasons for patients' catheterization; A catheter was placed in 5 patients, due to neurogenic bladder, 30 patients due to immobility, and 10 patients due to inability to urinate due to bladder outlet obstruction. All patients were successfully treated with the algorithm we applied.
Conclusions: In rare cases, failure to deflate the foley catheter balloon is a very disturbing situation for patients. However, complications, mostly minor, may occur during treatment. We think that this met-hod and algorithm we have described is a method that can be used safely like other methods.

Authors:   The Institute of Educational research Chonnam National University, Kim Minjeong
Published: December 2024

The purpose of this study is to explore learners' perceptions of peer assessment and evaluate its effectiveness based on the specificity of peer assessment criteria in teamᐨbased collaborative learning. The specificity of peer assessment criteria was examined through two independent variables: the use of detailed criteria and the presentation of evaluation grounds. Learners' perceptions were assessed via quantitative surveys and openᐨended questions focused on the usefulness and fairness of peer assessment, while the effectiveness was determined by the extent of equal participation in team activities, measured by actual team contribution scores. A total of 84 undergraduate students participated in the study. The findings revealed that the use of detailed criteria didn't show the statistical significance, but the provision of evaluation grounds significantly influenced learners' perceptions of the usefulness and fairness of peer assessment, though no interaction effect between the two was found. This suggests that regardless the use of specific criteria, evaluation grounds are provided enhances the perceived usefulness and fairness of peer assessment in evaluating team contributions. Moreover, the study found that group D (which used holistic criteria without providing evaluation grounds) demonstrated relatively unequal team contributions compared to other groups, highlighting the impact of specific peer assessment methods on team contribution within collaborative learning settings. To further clarify the quantitative results, openᐨended responses reflecting learners' perceptions of peer assessment were thoroughly reviewed to interpret the findings. The discussion was approached from the perspective of suggesting specific strategies for utilizing peer assessment to enhance learners' contributions in collaborative learning settings.

Seismic monitoring of the territory of the Northern Caucasus in 2020 was carried out by a seismic
network of 63 stations. The seismic network provided representative registration of earthquakes with KR≥7.0 in most
of the territory, in its central (including the Greater Sochi region) and eastern parts – with KR≥6.0, and in some local
zones – with KR≥5.5. In general, 3685 earthquakes were recorded in the region and its environs. 16 earthquakes were
felt in the Caucasus settlements, 26 of them occurred in the North Caucasus region. The maximum shaking intensity
Imax=5–6 according the MSK-64 was noted from the earthquake on December 12 with KR=12.9 on the territory of
the Chechen Republic (Tersk-Caspian forward trough). On the territory of Ossetia (Greater Caucasus), the Verkhne
Fiagdon earthquake of January 26 with KR=11.1 occurred. It was felt in populated areas up to I=4–5. Two notice
able earthquakes were registered in the Black Sea: on September 1 with KR=10.8 and on December 12 with
KR=10.5. They were felt in Krasnodar Region with intensity up to I=5 and I=4–5 respectively. In accordance with
the seismicity level scale "SOUS-09", seismicity of the North Caucasus in 2018–2019 is set as a "background average"
for the observation period from 1962 to 2020.

Authors: Zvereva A.S. , Skorkina A.A. , Gabsatarova I.P.
Published: December 2024

The spectral parameters of the sources of 38 earthquakes in the North Caucasus were determined
from the displacement spectra of S-waves for the period 2020. The calculations used events with an energy classes
KR=9.3–12.9 and waveforms from stations with epicentral distances 50–250 km. The values of local magnitudes
ML were calculated using a new calibration curve. The calculation of source spectra was carried out in the SEISAN
program based on the frequency-dependent quality factor Q(f). The following values were obtained: 0 – spectral
density, f0 – corner frequency, M0 – scalar seismic moment, Mw – moment magnitude,  – stress drop, and RMS
for each of the parameters. For 30 earthquakes with KR=9.0–12.9 focal mechanisms were calculated, which are
represented by reverse faults (including reverse faults with strike-slip components – 73 %), normal faults – 20 %
and strike-slip – 7 %, which corresponds to deformation processes in the collision zone of the Arabian and Eurasian
plates.

Published: December 2024

AI-based avatars embody human beings digitally and can interact with learners in real-time. Thanks to new LLM capabilities, they can perform numerous cognitive tasks and have advanced language capabilities. Available software solutions for the creation of AI-based avatars are frequently not grounded in educational theory and have yet to reach classrooms. In this technological contribution, we describe an authoring tool for creating AI-based avatars that builds on theories of situated learning. It allows users to conveniently create AI-based avatars with a web interface and distribute them via the web browser. Moreover, we report on the development of a collaborative learning application for language learning with an AI-based avatar as a teacher. A user study on this collaborative learning application demonstrated that learners view our avatars as authentic and are satisfied learning with them. We conclude with reflections on effective prompt engineering and insights into the characteristics of future AI-based avatars.

Drastic enhancements of direct and indirect light emissions from Ge microbridge web-structures via efficient light confinements
Authors: Inoue Takahiro , Odashima Ayaka , Nagao Masaki , Sawano Kentarou
Published: December 2024

Drastic enhancements of both direct and indirect light emissions are demonstrated from Ge microbridge web-structures fabricated based on the strained Ge-on-Si (110) substrate. This enhancement is concluded to be caused more predominantly by the light confinement effect in several-μm-scale microbridges than the induced strain. It is also remarkable that this effect works very well with a strain as small as 0.4%, making the fabrication procedure very easy and bridges very stable and rigid. These findings will, therefore, widen the applicability and raise the potentiality of here-proposed Ge web-structure microbridges toward Si optical integrated circuits.

Published: December 2024

The study sought to assess how visual impairment affects the performance of gender roles among Kipsigis women in Ainamoi Sub County in Kericho County. Among the Kipsigis, there are gender roles to be performed by men and women. Attributable to patriarchy and other socially constructed attributes, it is women who end up performing most of these gender roles in families. The research was conducted in Ainamoi Sub County, Kericho County. Households with visually handicapped women were its main goal. The investigation was guided by the social model of disability. The study employed a descriptive research methodology, and 166 participants who met the sample size were selected using a simple random selection procedure. A closed-ended questionnaire was used to gather data, and the Statistical Package for Social Sciences (SPSS version 21) was used for analysis. Descriptive statistics were used, and they were displayed as frequencies and percentages. Tables, charts, graphs, and summaries were used to display the data. Results showed that as a result of visual impairment, women in Ainamoi Sub County encounter challenges in mobility, identification and location of items and determination of quality. Challenges are also evident in meal preparation and cooking. Results showed that dependence on family and friends has seen visually impaired women navigate challenges, thereby perform their gender roles. It is recommended that family members motivate the visually impaired to perform their tasks. In cases of poor performance, family members should feel free to correct them. For businesses, it will be vital for them to provide necessary assistance to the visually impaired. For county and national governments, it is recommended that create awareness to minimize stigma on disability. It is also recommended that the visually impaired are involved in decision making before implementation of programmes and projects targeting them.

Published: December 2024

Ferrous iron toxicity is the most important problem of heavy metal research due to its widespread environmental occurrence and its harmful effects on plant growth and metabolism. Evaluating the impact of ferrous iron induced toxicity provides valuable insights into the biochemical and physiological responses of plants, including alterations in growth parameters, nutrient content and antioxidant defense systems. This study is aimed to investigate the effects of ferrous iron toxicity on growth, biochemical alterations and enzymatic antioxidant status in Capsicum annuum L. Experimental Capsicum annuum plants were divided into 4 groups. Group 1 served as control, received normal nutrients and water, while Groups 2, 3 and 4 were treated with increasing concentrations of ferrous iron 100, 200 and 400 mg respectively. The results demonstrated that ferrous iron significantly reduced several growth parameters, including germination percentage, root length, shoot length, fresh weight, dry weight and vigour index. Moreover, higher concentrations of ferrous iron led to a decrease in carbohydrate and protein levels, as well as reduction in the activities of important enzymic antioxidants such as catalase and superoxide dismutase indicating a weakened oxidative defense system. The findings highlight the harmful effects of ferrous iron toxicity in Capsicum annuum, underscoring the potential risks to agricultural productivity. This research not only deepens our understanding of ferrous iron induced toxicity but also emphasizes the necessity to developing strategies to protect crops from metal toxicity, ensuring sustainable agriculture and food security in contaminated environments.

Tesla valve response prediction and structure optimization using artificial neural networks
Authors:   Gao Tyantsyi
Published: December 2024

Ways to improve and optimize the Tesla valve design, the performance of which is extensively studied by combining artificial neural network (ANN) and response surface methodology (RSM) for a deeper analysis of valve performance are considered. Some key valve design parameters are selected for optimization using dipolarity (Di) and absolute pressure drop ratio (APDR) as response factors. Experimental data are obtained by numerical simulation. Forecasting models using ANN and RSM are built and their accuracy is compared. The developed two-stage Tesla valve demonstrated high efficiency in real-world conditions and can be effectively used as a check valve. The prediction results using the ANN model were more accurate than with the RSM model, and no retraining is required.

Interrelationship between power and geometrical parameters of a wheel
Authors:   Romanchenko M.I.
Published: December 2024

Expressions are obtained to determine the dependencies between the power and geometric parameters of the wheel when rolling in free, driven and braking modes, taking into account the longitudinal displacement of the center of the plot of normal reactions of the support surface relative to the geometric center of the tire contact pad. A linear relationship has been established between the displacement value and the coefficient of longitudinal force in the driven and braking rolling modes of the wheel. A graphical representation of the relationship between the power and geometric parameters of an automobile wheel with a Pirelli 11.0-R20 cargo tire in free and braking modes is presented. The above dependences between power and geometric parameters, taking into account the displacement of the center of the asymmetric plot of the normal reactions of the support surface, can find practical application in choosing and justifying optimal braking modes of automobile wheels in various road conditions.

Authors: da Silva Halecy Davidson Sousa , Franco Eryvelton de Souza , Lima Larissa Caroline de Almeida Sousa , Maia Maria Bernadete de Sousa
Published: December 2024

ABSTRACT Closure of the ductus arteriosus (DA) using cyclooxygenase (COX) inhibitors is considered the first-line treatment for hemodynamically significant patent ductus arteriosus (PDA). Physiologically, prostaglandins have a recognized role in PDA. Admittedly, the comparative efficacy and safety between ibuprofen and acetaminophen need to be determined for rational choice of drug therapy for closure of the DA in clinical protocols. This study aims to present the aspects of the efficacy and therapeutic safety of paracetamol versus ibuprofen in the treatment of PDA in premature newborns. A systematic review of the literature was carried out, following the recommendations of the PRISMA protocol, using the Medline, Pubmed, LILACS, and SciELO databases. Studies from the last 10 years (2013-2023) that analyzed the efficacy and/or safety of acetaminophen compared to ibuprofen in newborns diagnosed with PDA were included. Eight randomized clinical trials (RCTs) were selected for analysis, resulting in a sample size of 781 newborns with PDA treated with acetaminophen or ibuprofen. The efficacy of acetaminophen for DA closure is comparable to ibuprofen. There is no statistically significant difference in the incidence of related adverse effects between the two drugs in most studies. There is equivalence in the efficacy and safety of ibuprofen and acetaminophen to promote closure of the DA in premature newborns with hsPDA.

Índices inflamatórios sistêmicos proporção neutrófilo-linfócito (NLR), proporção monócito-linfócito (MLR), proporção plaqueta-linfócito (PLR), índice de inflamação imune sistêmica (SII), valor de inflamação pan-imune (PIV) e índice de resposta à inflamação sistêmica (SIRI) foram calculados. Índices inflamatórios sistêmicos foram comparados entre os grupos hsPCA e não hsPCA. Um p < 0,05 foi considerado estatisticamente significativo. Resultados Um total de 1228 pacientes foram incluídos no estudo, incluindo 447 pacientes no grupo hsPCA e 781 pacientes no grupo não-hsPCA. O valor PIV [mediana (Q1 - Q3): 5,18 (2,38-10,42)] no grupo hsPCA foi estatisticamente significativamente maior do que o valor PIV [mediana (Q1 - Q3): 3,52 (1,41-6,45)] no grupo não-hsPCA (p<0,001). De acordo com a análise ROC, o valor AUC do PIV para a previsibilidade de hsPCA foi de 0,618, e o nível de corte foi >8,66. Após até mesmo múltiplas análises de regressão logística, o PIV mostrou ser um parâmetro significativo para o diagnóstico de hsPCA (OR 1,972, IC 95% 1,114-3,011. p=0,001). Conclusões Um alto valor de PIV pode ser um indicador de uso rápido, baixo custo, simples e facilmente acessível para o diagnóstico precoce de hsPCA.

Published: December 2024

Abstract Background Increased oxygen tension and decreased prostaglandin levels cause ductal closure. The diagnostic role of systemic inflammatory indices in hemodynamically significant ductus arteriosus (hsPDA) in premature infants is unknown. Objectives We aimed to evaluate the role of systemic inflammatory indices in the predictivity of hsPDA. Methods Premature infants with gestational weeks (GW) of <32 weeks were evaluated retrospectively. Systemic inflammatory indices neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), pan-immune- inflammation value (PIV), and systemic inflammation response index (SIRI) were calculated. Systemic inflammatory indices were compared between hsPDA and non-hsPDA groups. A p <0.05 was considered as statistically significant. Results A total of 1228 patients were included in the study, including 447 patients in the hsPDA group and 781 patients in the non-hsPDA group. The PIV value [median (Q1 - Q3): 5.18 (2.38-10.42)] in the hsPDA group was statistically significantly higher than the PIV value [median (Q1 - Q3): 3.52 (1.41-6.45)] in the non-hsPDA group (p<0.001). According to the ROC analysis, the AUC value of PIV for the predictivity of hsPDA was 0.618, and the cutoff level was >8.66. After even multiple logistic regression analyses, PIV was shown to be a significant parameter for the diagnosis of hsPDA (OR 1.972, 95% CI 1.114-3.011. p=0.001). Conclusions A high PIV value may be a quickly used indicator with low-cost, simple, and easily accessible for the early diagnosis of hsPDA.

Background: Human immunodeficiency virus (HIV) is a significant concern in the field of global health. However, studies on the relationship between viral load, opportunistic infections, and quality-of-life among them are limited.
Objectives: This study aims to determine the relationship between viral load count, the presence of opportunistic infection, and the quality-of-life among people living with HIV.
Methods: A cross-sectional study was used involving 35 respondents recruited through convenience sampling. The quality-of-life of individuals living with HIV was assessed using the World Health Organization Quality-of-Life instrument for HIV. Statistical analysis using descriptive statistics, including mean, standard deviation, and proportion, and bivariate analysis with p-value<0.05.
Results: Of the 35 participants, the majority were male (57.1%), with a mean age of 41.63 (9.09), and had a low education level (51.4%). The mean quality-of-life score was 86.88 (12.27), with a mean duration of ARV treatment of 7.23 years (5.36), undetectable viral load (68.6%), living with opportunistic infections (80%), and with tuberculosis being the most common (52.63%). There was a significant correlation between viral load and overall quality-of-life (p-value 0.04).
Conclusion: The results of viral load testing and the identification of opportunistic infections can serve as indicators to assess the quality-of-life among people living with HIV. The outcomes of this study have practical implications for enhancing healthcare services in clinical settings.
