Authors: Mhlongo Thabo 
Published: February 2025

Abstract

This mixed-methods study examined teachers' perceptions of integrating coding and robotics into the science curriculum in Mpumalanga Province, South Africa. With an increasing need to equip learners with 21st-century skills, the study explored teachers’ preparedness, challenges, and recommendations for effective implementation. Data were collected from 47 teachers using a stratified purposive sampling approach. A structured questionnaire assessed attitudes, technology awareness, and professional development experiences, while open-ended responses provided qualitative insights. Findings indicated positive attitudes toward coding and robotics but highlighted concerns about inadequate training, resource constraints, and varying technological competency levels. Key barriers included insufficient infrastructure, limited professional development, and cultural perceptions. Statistical and thematic analyses identified significant relationships among these factors. The study recommends targeted teacher training, improved resource allocation, and collaborative networks to support successful implementation. These strategies aim to enhance teacher capacity, foster innovation, and ensure learners are well-prepared for the digital age.
Multimodal Transformer for Heart Disease Classification Using Multiple Heart Sound Spectral Analyses and Clinical Metadata
Authors: Fujisawa Shintaro , Fukazawa Yusuke 
Published: February 2025

Abstract

This study proposes a multimodal fusion framework for heart disease classification that combines multiple spectral analyses of heart sounds with clinical metadata. Our framework integrates four complementary spectral analysis methods (Stockwell transform, bispectrum, mel-spectrogram, and power spectrum) using Vision Transformers. This spectral fusion is further enhanced by incorporating clinical metadata processed through Bio\_ClinicalBERT, enabling the capture of diagnostic insights from specialist physicians. Our framework achieved superior performance, with the model that fused both spectral features and clinical data reaching an accuracy of 0.881. This fusion model outperformed the individual spectral models, which had an accuracy of 0.831, by 6\%. Additionally, incorporating clinical metadata resulted in a 2.6\% improvement in accuracy compared to the model that fused only the four spectral features, which had an accuracy of 0.855. Through SHAP analysis, we discovered that our model excels at detecting right-heart abnormalities, which are often difficult to identify through traditional auscultation. Furthermore, we identified the Stockwell transform and mel-spectrogram as particularly influential features. The Stockwell transform's ability to localize both time and frequency information allowed our model to capture transient patterns crucial for detecting subtle heart sound abnormalities. Similarly, the mel-spectrogram, designed to mimic human auditory perception, excelled in highlighting frequency-related features commonly recognized by clinicians.

Managing sanitation in unplanned urban areas: insights into manual emptying of onsite systems in Tandale, Dar es Salaam
Authors: Stephen Anna , Kimwaga Richard , M. M. Mulungu Deogratius , Izdori Fides 
Published: February 2025

ABSTRACT

Achieving Sustainable Development Goal 6.2 in unplanned urban settlements seems to be a challenge due to climate variability and population growth, which strain existing sanitation services. The study found out that all residents of Tandale rely on on-site sanitation facilities, with 70.8% using pit latrines, 27.1% using septic tanks, and the remainder utilizing eco-friendly options like Aqua privies (0.3%) and Eco-san (1.8%). Emptying is necessary as space is limited for digging new pits. About 52.4% of households use vacuum trucks, while manual emptying remains a significant practice at 24.9%, with 5.7% of residents discharging waste directly into drains and 17.0% never emptying their latrines. The high water table, narrow streets, and limited resources further complicate sanitation efforts, while climate variability, particularly flooding, exacerbates pit overflows and increases health risks. Additionally, the 9.19 km distance to the disposal site and uneven terrain hinder the feasibility of simplified sewers or gravity-based systems. Recognizing the impracticality of eliminating manual emptying, this study recommends that manual emptiers should be empowered to provide safer and more efficient services. Integrating Decentralized Wastewater Treatment Technology (DEWATT) with improved Manual Emptying Technology (MAPET) will offer a locally affordable and sustainable solution.

The presence of stray dogs in a community represents a significant risk factor in the spread and maintenance of Leptospira by acting as pathogen reservoirs and potentially transmitting the bacteria to household dogs and the peri-domestic environment, increasing the risk of zoonotic transmission of the disease. Here, we utilized an indirect ELISA employing recombinant LipL32 protein to detect IgG antibodies to Leptospira in serum samples from stray dogs in Mexicali, Northwest Mexico. Serum samples (n = 331) from stray dogs were collected from 2017 to 2020 and tested with the ELISA-LipL32. The results showed an overall seroprevalence of 46.52 % (154/331) over the four years, 46.36 % (51/110) in 2017, 57.95 % (51/88) in 2018, 28.85 % (15/52) in 2019, and 45.68 % (37/81) in 2020. The high prevalence of serum antibodies to Leptospira among the stray dog population indicates that Mexicali provides optimal ecological conditions for maintaining and disseminating leptospire throughout the city, increasing the risk of infection to other domestic or companion animals and the human population. Further epidemiological research is necessary to identify the serovars in the region and propose strategies to control the stray dog population and the propagation of Leptospira in the Northwest region of Mexico.

Introduction: Basketball-specific high-intensity interval training (HIIT) has been documented to be a time-efficient, skill focused training method for enhancing the aerobic performance. The aim of this study was to investigate the effects of basketball-specific HIIT on aerobic capacity in adolescent female basketball players. Materials and methods: Participants were 16 female basketball players, aged 13-15 years. They were equally and randomly divided into two groups: a control group and an experimental group. The subjects from the experimental group performed a basketball-specific HIIT protocol for 6 weeks (2 times per week, 25 minutes per session), before the basketball training. The control group followed a basketball training program for the same period, with the same frequency (2 times a week, 90 minutes per session). Pre- and post-intervention, the multi-stage fitness (beep) test was used to assess aerobic endurance. Results: After 12 training sessions, the experimental group showed a significant increase in test scores (p = .002, with a mean difference of 1.263). When compared to the control group, post-intervention, the experimental group showed significantly higher test scores (p < .001, with a mean difference of 1.69). The findings suggest that aerobic endurance increases in adolescent basketball athletes after 6 weeks of training. Conclusion: Basketball-specific HIIT appears to be a solid option for improving aerobic performance in adolescent female players while maintaining focus on basketball skills.

Energy-efficient Q-learning-based routing in wireless sensor networks
Authors: Chaudhari Archana , Deshpande Vivek , Midhunchakkaravarthy Divya 
Published: February 2025

Abstract
Wireless sensor networks (WSNs) are extensively used to collect and transmit data from the environment through sensor nodes for various applications such as agriculture, medicine, and military. The sensor nodes are located in remote locations and harsh environmental conditions. Sensors operate on a limited power source. The lifetime of the entire WSN depends on the power of its nodes. Also, successful data transmission via routing from the source node to the destination depends on the battery life of the sensor node. It therefore becomes necessary to have an energy-efficient routing path to ensure successful packet delivery from source to sink nodes. The work proposes an energy-aware Q-learning-based routing algorithm in WSN. To establish an energy-efficient route, the work exploits the rewards in Q-learning based on the node energy. Experiments conducted using the proposed work demonstrate enhanced packet delivery, throughput, and networks lifetime. A comparison of the work with a basic Q-learning-based routing algorithm exhibits improved performance.

Published: February 2025

Abstract
This paper presents the findings of a study on dose rate distribution in air and water phantoms, recorded using Gafchromic films. Low energy accelerator with X-ray tube (NALR), a system developed at the National Centre for Nuclear Research (NCBJ), generated by the dose rates. The primary objective of this research was to employ the X-ray tube as a source of X-ray radiation and assess dosimetry techniques using radiochromic films for radiological protection purposes. Gafchromic MD-55-V2 and EBT films were utilized for measurements. Two-dimensional measurements with Gafchromic dosimetry films were compared against ionization chambers AP 2.0 (in water) and PTW-23342 (in air) to validate radiation dose rate distributions. Furthermore, the film response over different days post-exposure highlights the importance of scanning radiochromic films on the first day after exposure.

На сегодняшний день существуют два принципиально различных хирургических подхода к хирургическому лечению пациентов с заболеваниями верхнечелюстной пазухи: экстра­назальный (через трепанационное отверстие в передней стен­ке верхнечелюстной пазухи) и эндоназальный (через средний носовой ход). Экстраназальный доступ обеспечивает хороший обзор операционного поля, что позволяет надежно удалить патологическую ткань из всех отделов пазухи, однако сопро­вож­дается травмированием мягких тканей лица и болью в проекции вмешательства в послеоперационном периоде. С по­яв­лением эндоскопической техники хирурги начали удалять че­рез естественное соединение верхнечелюстной пазухи в об­лас­ти среднего носового хода. Этот метод позволяет избе­жать травмирования передней стенки пазухи. В связи с чем, цель сос­тоит в том, чтобы проанализировать преимущества и недос­тат­ки экстра- и эндоназального доступа к верхне­челюстной пазухе на сегодняшний день.

To date, there are two fundamentally different surgical ap­proa­ches to the surgical treatment of patients with diseases of the maxi­llary sinus: extranasal (through a trepanation hole in the an­te­rior wall of the maxillary sinus) and endonasal (through the middle nasal passage) Extranasal access provides a good overview of the surgical field, allows you to reliably remove sinuses from all parts, but is accompanied by injury to the soft tissues of the face and pain in the projection of intervention in the postoperative period. With the advent of endoscopic techniques, surgeons began to remove the maxillary sinus in the middle nasal passage through the natural con­nection. This method avoids injury to the anterior wall of the sinus. The aim is to analyze the advantages and disadvantages of extra- and endonasal access to the maxillary sinus to date.
