Published: January 2025

Background. Already from the beginning of the ­COVID-19 epidemic, both in Ukraine and in the world, there was a problem of providing trauma care to victims with traumatic injuries, which was combined with similar problems with medical care for other categories of patients. The system of routing patients with hip fractures against the background of COVID-19 during the epidemic period, depending on the severity of the course, will allow to organize a system of providing medical care to such patients, which will correspond to both the personnel and material resources necessary to overcome the consequences of this pandemic. The aim of our study was to analyze the distribution of patients with femur fractures during the COVID-19 epidemic and to determine changes in approaches to their treatment. Materials and methods. To conduct our study, we retrospectively analyzed the treatment of 289 trauma patients who underwent inpatient treatment in 2019–2021. Results. The number of surgical interventions in patients with hip fractures decreased by only 2.8 %, which indicates the absence of changes in the tactics of treatment of patients with this pathology during the epidemic period. There were no changes in the number of patients with diaphyseal femur fractures; their number was constant in both research periods. However, during the epidemic period, an increase in the level of surgical interventions in patients with fractures of the diaphyseal part of the femur was found. During the COVID-19 epidemic, there was a decrease in the number of victims with fractures in the distal part of the hip. During the epidemic period, the rate of distal hip fractures decreased by 6.0 %. An increase in ope­rative activity was found in relation to patients with fractures of the distal part of the femur in the pre-operative period. Conclusions. In the period of COVID-19, the number of patients with hip fractures increased, and no changes in the structure of treatment of patients in this category were found. During the COVID-19 epidemic, there were no changes in the number of patients with diaphyseal hip fractures, their number was constant in both research periods. However, during the epidemic period, an increase in the level of surgical interventions in patients with fractures of the diaphyseal part of the femur was found. During the epidemic period, there was a decrease in the level of victims with fractures in the distal part of the thigh by 6.0 %, and an increase in operative activity was detected in relation to patients from this category.

Direct Position Estimation (DPE): A Potential Application in Geodetic Networks
Authors: Mudita Imam
Published: January 2025

Direct Position Estimation (DPE) is a relatively new technique in the Global Navigation Satellite System (GNSS) that is used to estimate the user’s position, velocity, and time directly from the correlation values of the received GNSS signal with the internal replica signals of the receiver. Unlike the conventional two-step approach, DPE infers the position directly from the sampled data without intermediate steps by joining signal tracking, and the navigation technique directly compares the expected signal reception of multiple potential navigation candidates against the actual received signal. The theoretical results indicate that DPE-based GNSS receivers can achieve more robust localization than conventional two-step receivers. DPE localization algorithms that compute the navigation solution directly in the navigation domain have been proposed, providing ways to address the challenges of conventional two-step receivers at the expense of additional computational load. Despite its high computational load, DPE is a more robust positioning algorithm than conventional two-step receivers in terms of multipath mitigation. The resilience of DPE against multipath and non-line-of-sight can even potentially offer applications in geodetic networks, where robust estimators are traditionally employed to counteract outliers.

Authors: Hasyim Faisal Ammar
Published: January 2025

Banjir sering terjadi di berbagai daerah di Indonesia, termasuk di Kota Pekalongan. Kajian InaRISK BNPB menyatakan bahwa semua kecamatan di Kota Pekalongan memiliki potensi bahaya banjir dengan tingkat sedang hingga tinggi. Keberadaan Daerah Aliran Sungai (DAS) Kupang merupakan salah satu faktor yang berpengaruh terhadap banjir di Kota Pekalongan. Seiring berjalannya waktu, DAS Kupang mengalami perubahan penggunaan lahan yang dapat mengurangi kemampuannya sebagai daerah resapan air. Genangan banjir sering terjadi saat Sungai Kupang meluap akibat hujan deras dan pasang air laut. Data dari Dinas Pekerjaan Umum Sumber Daya Air dan Penataan Ruang Provinsi Jawa Tengah menunjukkan bahwa Sungai Kupang telah meluap dan menyebabkan banjir sebanyak delapan kali dari tahun 2016 hingga 2022. Penelitian ini bertujuan untuk mengkaji pengaruh perubahan penggunaan lahan terhadap debit puncak di DAS Kupang melalui pemodelan debit menggunakan program HEC-HMS dengan metode Soil Conservation Services yang diterapakan pada kondisi penggunaan lahan tahun 2019, 2021, dan 2023. Debit hasil pemodelan digunakan dalam pemodelan banjir menggunakan program HEC-RAS. Analisis hasil pemodelan banjir didasarkan pada perbedaan data debit dan tinggi air laut yang digunakan dan dampaknya terhadap penggunaan lahan. Hasil penelitian menunjukkan bahwa perubahan penggunaan lahan secara bersama-sama berpengaruh signifikan terhadap debit puncak di DAS Kupang. Hasil pemodelan banjir menunjukan bahwa luapan Sungai Kupang tetap terjadi pada kondisi debit dan tinggi air laut minimum namun akan meluas pada kondisi debit dan tinggi air laut maksimum. Luapan Sungai Kupang paling banyak melanda Kecamatan Pekalongan Utara, khususnya terhadap badan air atau tambak dan pemukiman.
Sex of Things – An exploration of Bill Brown’s things through the lens of gender
Authors: Chatterjee Nivedita
Published: January 2025

Bill Brown’s ‘Thing Theory’ (2001) introduces the radical idea of the difference between ‘objects’ and ‘things’. For Brown an object is an entity which is functional and therefore obedient and docile drawing no significant attention from the user. A thing on the other hand is a recalcitrant object who has shed its utilitarian property and specifically by becoming non-functional makes its presence felt in the user’s /onlooker’s consciousness. This chapter uses Brown’s ‘Thing Theory’ (2001) as a tool to demonstrate that objects can be explored as both gendered and gender-ambivalent entities following their anthropomorphisation — a mass scale phenomenon Brown himself emphasises. This chapter argues that through the process of humanisation and subsequent internalisation objects can impact human perception of themselves in lasting and therefore powerful ways.
An Overview of the Methodologies in Drought Forecasting
Authors: R Angel
Published: January 2025

Drought has resulted in the massive destruction of lives, livestock and economy, locally and globally. Under the current
circumstances, the dry weather conditions are prevalent leading to water stress resulting in imbalance of the ecosystem. The
persistent dry weather eventually results in drought conditions, which indirectly affects the economy of the country. As a result, it
has become imperative to assess and mitigate the effects of the droughts. With the advancements in the machine learning
techniques, there has been a substantial improvement in the level of accuracy of the prediction of drought events. The
motivation of this paper is to review those machine learning techniques such as Extreme Gradient Boost, ARIMA, Long ShortTerm Memory (LSTM), Random Forest used in forecasting drought events. Considering the extensively used drought indices,
that is, the Standard Precipitation Index (SPI) and Standardized Precipitation Evaporation Index (SPEI) together with the
various meteorological parameters, the influence of the climate variables on drought forecasts are given more importance in the
present study. This study also includes review on single and hybrid models used for forecasting droughts. Further the gaps in the
reviews have been identified by critically observing the studies in the research articles which will enhance the efficiency of the
predictive models.
A Review: Study on Pharmacological Actions and Phytoconstituents of Saffron
Authors: Dwivedi Harshit
Published: January 2025

In recent years, there has been growing interest in isolating and examining novel bioactive compounds from natural
sources with significant health benefits. Saffron, derived from the dried stigmas of Crocus sativus L., has been traditionally used
for centuries in medicine due to its therapeutic properties and potential to address various pathological conditions. This review
aims to explore the medicinal attributes of saffron, evaluate its potential applications in modern medicine for treating a wide
range of disorders, and summarize both early and current evidence regarding the biological and pharmacological activities of
saffron and its active constituents, crocin and safranal.
Key Findings: Recent phytochemical and pharmacological studies highlight that crocin and safranal exhibit significant
activities, including antioxidant, anti-cancer, anti-diabetic, anti-inflammatory, and anti-atherosclerotic effects. However, most of
this evidence is derived from in vitro studies, with limited in vivo research supporting these claims. Additionally, although some
clinical trials provide preliminary evidence of saffron's ability to alleviate depression and enhance cognitive function in
Alzheimer’s patients, more robust studies are needed to confirm these effects

Determinants of tax avoidance disclosure moderated by firm size
Authors: Sari Nihayatul Maula , Nurdin Fajar
Published: January 2025

Purpose: This study aims to analyze the effect of sales growth, profitability, and inventory turnover on tax avoidance moderated by firm size.
Methodology/approach: This study uses secondary data from firm financial statements in a quantitative research approach. Companies in the real estate and property sectors that are listed on the Indonesia Stock Exchange (IDX) between 2020 and 2023 make up the population. 34 samples in all were chosen using a purposive selection technique, and moderated regression analysis (MRA) was performed using EViews software.
Findings: The study's findings show that while profitability and inventory turnover significantly reduce tax avoidance, sales growth has little influence on the practice. Firm size can minimize the impact of profitability on tax avoidance, but it has no influence on the link between sales growth and inventory turnover and tax avoidance.
Practical and Theoretical contribution/Originality: It is anticipated that the Directorate General of Taxes will use the findings from this study as a guide when evaluating corporate tax evasion. It also explains how business size influences the relationship between tax avoidance and inventory turnover, profitability, and sales growth.
Research Limitation: Because businesses have not been consistent in releasing financial reports over the 2020–2023 timeframe, and because the metrics are restricted to proxies for firm size, sales growth, profitability, and inventory turnover, this study has a narrow focus.  Additionally, only publicly available secondary data specifically, financial reports are used in data collecting.

Authors: Morais Júnior Rui Rosa de , Behenck Aramburu Arthur , Missio André , Beltrame Rafael , De Avila Delucis Rafael , Gatto Darci Alberto
Published: January 2025

This study presents an innovative approach to wood mineralization through various pretreatments, focusing on the application of chemically treated sawdust as aggregates in fly ash-based geopolymer composites. Eucalyptus wood sawdust underwent five distinct treatments: cold water washing (CWW), hot water washing (HWW), sodium hydroxide washing (SHW), calcium hydroxide mineralization (CHM), and Portland cement mineralization (PCM). Comparative analyses revealed that the properties of these geopolymer composites were comparable to, or exceeded, those achieved with traditional sand aggregate. The incorporation of the pretreated wood aggregates resulted in geopolymer composites with comparable compressive strength values at 30 and 90 days, with further strength improvements after aging especially for composites treated with HWW or SHW. Additionally, these composites exhibit the formation of a mineral layer on the wood surface, confirming successful mineralization. This study concludes that HWW and SHW treatments significantly enhanced the compatibility between wood and the geopolymer matrix, paving the way for developing light weight geopolymer composites with promising applications in the sustainable building materials.

Authors: Febriansyah Muhammad Zulfahmi , Raharno Sri , Setyawan Harry Prayoga
Published: January 2025

Industry 4.0 promotes the use of Cyber-Physical Systems (CPS) to improve production efficiency through seamless data exchange between virtual and physical components. However, in manual labor-driven environments, discrepancies between virtual stock data and actual material usage can create challenges for accurate production monitoring. This study focuses on addressing these discrepancies by integrating a stock-taking method into a production monitoring system. The system was implemented in an air conditioning train car assembly workshop, where differences of 2–3% between the predicted virtual stock and real-world quantities were identified. By applying the stock-taking method, virtual data were recalibrated to reflect real-time stock levels more accurately. The system's ability to track material usage and losses allowed for significant improvements in inventory accuracy, with immediate updates provided to the CPS. This approach minimizes human error in manual operations, ensuring that material predictions are more aligned with actual consumption. The results show that the implementation of the stock-taking method reduced the margin of error in stock predictions, improving overall production decision-making. These findings suggest that this method can enhance stock accuracy in manufacturing sectors, particularly in developing countries where manual labor is predominant. This study provides practical implications for optimizing material management and reducing production costs by leveraging CPS integration with stock-taking methods.

Published: January 2025

Este artigo apresenta a análise de uma experiência sobre a resolução de um exercício de matemática em sala de aula envolvendo o cálculo de área de um losango e a sua transformação em problema de matemática usando a Teoria dos Registros de Representação Semiótica, de Raymond Duval. Mais precisamente, pretende-se mostrar através desta experiência que o software de geometria dinâmica GeoGebra contribui para a transição de um exercício para um problema, passagem esta que se fundamenta na exploração e mobilização dos diferentes tratamentos e conversões em diferentes representações semióticas. A atividade foi desenvolvida em uma turma de estudantes do segundo ano do Ensino Médio, com o uso do GeoGebra sendo fundamental para um estudo mais dinâmico do objeto geométrico, permitindo aos alunos manipular o objeto, identificar elementos e enriquecer a figura com diferentes objetos geométricos. A análise dessa abordagem evidencia que o GeoGebra potencializa tanto a construção de tratamentos no registro figural quanto a interação dos alunos com o objeto, possibilitando um novo olhar sobre alguns tópicos de geometria e uma participação mais ativa na produção de conhecimento.

Natural dyes are one of the popular choices for textile dyes today. One part of the plant that has the potential to produce natural dyes is cocoa pod husk (Theobroma cacao L.) because it contains several secondary metabolite compounds, such as tannin which produces a brown color. The extraction method used in this research is Ultrasonic Assisted Extraction (UAE). This study aims to obtain the highest yield of natural dye extracts from cocoa pod husk by varying solvent types, extraction time, and material-to-solvent ratios using the UAE method. In addition, the types of compounds contained in extracts of natural dyes and color results on cotton fabrics were also obtained. The extraction process was carried out using several types of solvents, namely methanol, ethanol, acetone, and distilled water with varying extraction times of 30, 60, and 90 minutes. The research results show that the solvent that can extract the best natural dyes was ethanol with a yield of 11.43% and an extraction time of 90 minutes. Variable ratios of material to 96% ethanol solvent were also observed, namely at ratios of 1:5, 1:6, 1:7, and 1:8 for extraction times of 30, 60, 90, and 120 minutes. The research results were obtained for the ratio of material to ethanol solvent; 1:8 (w/v) and extraction time 120 minutes with a dye yield of 12.29%. The results of the UV-visible spectrophotometry analysis were obtained that the maximum wavelength of cocoa pod husk extract was 656.5 nm with an absorbance of 0.532. The results of the Gas Chromatography-Mass Spectrometry (GC-MS) analysis were obtained that the dye compound in the cocoa pod husk was tannin. Tannin compounds are natural dyes that can be applied to fabrics and will reduce the use of synthetic dyes. The application of dye extracts to cotton fabrics produced a brown color.

The increase in carbon emissions resulting from industrial activities has become a major concern for environmental and climate conditions. Carbon Capture and Storage (CCS) represents a significant effort to mitigate the CO2 problem. Aceh Province possesses a potential distribution of serpentine, which may serve as an effective material for CCS applications. This study evaluates the effects of gas flow rate, particle size, sorbent weight, and pressure on CO2 adsorption using chemically activated serpentine. The activation process involved hydrochloric acid (HCl) at three concentrations: 8%, 9%, and 10%, with particle sizes of 50 mesh, 100 mesh, and 150 mesh. Activation was conducted at room temperature with an acid-to-serpentine ratio of 10:1 for 30 minutes. Adsorption tests were performed at ambient temperature under pressures of 2, 3, and 4 bar, with adsorption times of 30, 60, and 120 minutes. Results indicate that activated serpentine treated with 9% HCl and a particle size of 150 mesh achieved the highest performance, demonstrating an adsorption efficiency of 33.01% and an adsorption capacity of 82.22% (0.0488 g CO2/g adsorbent) at a pressure of 2 bar. Both the Langmuir and Freundlich isotherm models closely fit the data (R² = 1). This study concludes that HCl activation significantly enhances the capacity and efficiency of serpentine as a CO2 adsorbent.

Authors: Siems Maria Edith Romano
Published: January 2025

A discussão que aqui apresentamos aborda as questões que envolvem os Serviços Educacionais Especializados em Educação Especial e como temos observado sua trajetória nas pesquisas que temos desenvolvido. O cerne da reflexão encontra-se nas perspectivas de compreensão da deficiência que orientam as práticas em educação especial e, como observado em nossos dados de pesquisa, em especial as de abordagem documental e histórica, vemos a retomada do modelo médico-biológico de compreensão da deficiência e uma intensa disputa dos profissionais e serviços de natureza clínica, pelos recursos orçamentários da Educação, explicitado na proliferação de Centros Especializados e da contratação de serviços e profissionais de apoio que desenvolvem atividades de natureza terapêutica, com frágeis vinculações à educação escolar. Trata-se de apresentação realizada durante a programação da quinta reunião da seção regional norte da ANPEd ocorrida em setembro de 2024 na Universidade Federal de Roraima – Campus Boa Vista.
Advanced sentiment analysis techniques to detect users’ perceptions related to the “health” of a railway company: Some evidence from European countries
Authors: Pagliara Francesca , Cutolo Ginevra , Sperlì Giancarlo
Published: January 2025

In this paper advanced Sentiment Analysis techniques were applied to evaluate public opinions reported by rail users with respect to four major European railway companies, i.e., Trenitalia and Italo in Italy, SNCF in France and Renfe in Spain. Two powerful language models were used, RoBERTa and BERT, to analyze big amount of text data collected from a social platform dedicated to customers reviews, i.e., TrustPilot. Data concerning the four European railway companies were first collected and classified into subcategories related to different aspects of the railway sector, such as train punctuality, quality of on-board services, safety, etc. Then, the RoBERTa and BERT models were developed to understand context and nuances of natural language. This study provides a useful support for railways companies to promote strategies for improving their service.
Visual Metaphor and Narrative: Ekphrasis in Fictional Narrative Prose of Late Antiquity
Authors: Paskaleva Bogdana
Published: January 2025

This article presents an interpretation of some functions performed by ekphrastic structures in the context of Ancient fictional narrative prose. Concrete examples are taken from two Ancient Greek novels: Daphnis and Chloe by Longus and Leucippe and Clitophon by Achilles Tatius. Using Olga Freidenberg’s conceptual and interpretative apparatus as a lens for reading the textual material, the central claim of the article is that within Ancient prose narrative, ekphrasis and metaphor are functionally interrelated, with ekphrasis serving to metaphorically embed narrative content within the mythological, affective, and genre-related fields of the textual production of meaning. At the same time, while adopting Freidenberg’s definition of metaphor as a primal state of cognitive indistinction between image and concept, the article attempts to go beyond her mythological interpretation of the Ancient novel and to provide a more socially and historically relevant understanding of the semantic features of this genre.
