The results showed that children in the experimental group experienced a significant increase in conceptual understanding compared to the control group, with an average increase in mathematical concept understanding. In addition, e-modules have also been shown to increase children's interest in learning and active involvement in the learning process. Obstacles faced during the study included limited access to technology and the need for training for teachers to optimally utilize e-modules. In conclusion, e-modules for early science and mathematics development are effective in improving conceptual understanding in early childhood, as long as they are supported by adequate infrastructure and good teacher competence in operating them.
Faecal microbiota transplantation in the management of obesity and type two diabetes mellitus
Authors:   , Cunningham Andrew L.
Published: February 2025

Obesity and type two diabetes mellitus (T2DM) represent complex metabolic disorders that continue to evolve into major global public health challenges, which impose a substantial burden on health infrastructure and resources. Contributing to the pathophysiology of these conditions is the gut microbiome, a vast community of trillions of bacteria coexisting within the human bowel which play a pivotal role in human metabolism. While a substantial body of literature has offered evidence supporting the involvement of the gut microbiota in metabolic diseases, the field remains in its early stages of development. The basic understanding of gut microbiota pathophysiology has sparked considerable interest in utilising microbiota for clinical applications. One rapidly emerging clinical modality is faecal microbiota transplant (FMT), designed to target and modify the intestinal microbiota which has demonstrated high effectiveness in the treatment of recurrent Clostridioides difficile infection. Although a small number of studies exploring FMT's potential to improve metabolic parameters have shown some early promise, it is important to note that this research is currently in the hypothesis-generating phase. This thesis delves into the development of, and analyses the results of a randomised feasibility study aimed at investigating FMT as a potential management strategy for individuals with T2DM and concurrent adiposity. The research encompasses a comprehensive examination of the microbiota profile of study participants revealing taxonomic differences, reduced alpha diversity metrics, and statistical associations with clinical biomarkers both before and after intervention. Additionally, it also includes an assessment of the clinical efficacy of FMT concerning biomarkers related to adiposity and glucose-insulin homeostasis, and explores the impact on participants' quality of life utilising a generic health status measurement tool. Lastly, it details an account of the successful establishment of a non-related frozen faecal donor programme.

Key Audit Matter and Audit Report Lag: A Preliminary Evidence from Indonesia
Authors: Yulianto Ahmad Rudi , Lokman Norziana , Mohd Razali Fazlida
Published: February 2025

The purpose of this study is to explore the potential influence of key audit matter on audit report lag. The authors analyzed data from key audit matter reporting in Indonesia for Indonesian public companies to test the relationship between the number of key audit matters and audit report lag. Data obtained from annual reports and multivariate linear regressions were employed to test the hypotheses. We find that key audit matters disclosure does not affect audit report lag. This suggests that audit firms in Indonesia may be treating key audit matters reporting superficially, as the selection of reported key audit matters does not appear to be closely linked to the audit efforts required to address these matters. The article focuses only on the Indonesian context, which limits generalizability. The results of this research will be informative for assessing the economic impact of key audit matter disclosures, which should be important for regulators, auditors, and accounting researchers. To the best of the authors’ knowledge, no prior study has examined key audit matters and audit report lag in Indonesia. This research contributes to the limited body of work exploring the consequences of key audit matters in developing country markets, particularly in Indonesia. It is also the first study to demonstrate that key audit matters are associated with delays in audit reports in Indonesia following the implementation of key audit matters in 2022.

Representações do corpo na literatura contemporânea escrita por mulheres: uma análise de A gorda, de Isabela Figueiredo
Authors: Magalhães Alessandra
Published: February 2025

Este artigo propõe uma reflexão sobre como a literatura escrita por mulheres vem representando os corpos femininos e suas complexas experiências. Para isso, analisarei o romance A gorda, da escritora portuguesa Isabela Figueiredo, publicado em 2016, que narra as memórias de uma protagonista submetida a uma cirurgia bariátrica. A alteração em seu corpo visa construir uma nova subjetividade, já que ela deseja experimentar uma vida em que não seja vista como um ser desprezível por ser gorda, pois seu corpo sempre foi alvo de repúdio desde a adolescência. Assim, mesmo que o papel da literatura na formação do imaginário social tenha se tornado mais relativo, ela ainda ocupa um lugar importante como forma de provocação e reflexão. Considerando que as narrativas literárias podem construir novos e variados – inclusive divergentes – olhares sobre o mundo, é fundamental refletir sobre o papel da literatura de autoria feminina na formação de um imaginário social acerca do corpo.

Trânsito e narração: os sentidos da viagem em Simpatia pelo demônio, de Bernardo Carvalho
Authors: Silva Alex Bruno da
Published: February 2025

Este trabalho propõe uma reflexão sobre o deslocamento do protagonista Rato no romance Simpatia pelo demônio, de Bernardo Carvalho. O objetivo é problematizar de que modo a representação do espaço transnacional, como território enunciativo da narrativa, articula-se à composição de uma personagem que, na crise da meia-idade, busca viver, na deambulação espacial, experiências homoeróticas e essa busca provoca uma necessidade de preenchimento íntimo, seja através do des/re/conhecimento de suas fragilidades, seja através da descoberta de sua essência ambígua. A partir disso, com base nas proposições de Marc Augé (1994; 2006; 2010), Tim Cresswell (2006) e Doreen Massey (2015), o recorte analítico focaliza ações e imagens de mobilidade presentes na obra, de forma que as implicações contidas no trânsito se desdobram em errância existencial.

Authors: Teixeira Nuno de Brito e Sousa
Published: February 2025

Este estudo centra-se na visão do chão na poética de Drummond que se estabelece como ângulo de observação, mas também de movimento e de arte poética que serve a construção das bases da sua poesia, movimento contínuo e transversal à sua criação pelo qual o sujeito poético se autocaracteriza. O objetivo deste trabalho é analisar esta perspectiva aliando-a a outros recursos que nos remetem para a concretização e a plasticidade das imagens. Por fim este trabalho centra-se por isso na forma como esta perspectiva é uma forma de intensificação da realidade que se conecta também a uma experiência de erotismo.
Thermophoresis of an aerosol cylinder in Brinkman medium within a cylindrical cavity
Authors: Nishad Shekhar , Madasu Krishna Prasad
Published: February 2025

This work presents the thermophoretic migration of a solid cylinder, whose direction is normal to its axis and situated in a concentric cylindrical cavity. The space between the particle and the cavity is filled with isotropic porous medium. The Kundsen number is considered to be small, so that the fluid flow through the porous medium is in continuum regime. The continuity of heat flux, temperature jump, viscous slip, thermal creep and thermal stress slip conditions are employed to solve the thermal transport and fluid flow equations. We have obtained analytical expressions for thermophoretic velocity, thermophoretic mobilities and drag force. The effects of the permeability, frictional slip parameter, particle-to-cavity radii ratio, and thermal conductivity ratio of particle to medium on thermoosmotic velocity, thermophoretic mobility and net normalized velocity are presented in graphical form. We have found that the thermoosmotic and thermophoretic mobility have maximum for the high permeability, and for the low radii ratio of particle to cavity. Reduction cases for the unbounded medium are also obtained. The present study has significant applications in industrial and engineering fields, such as manufacturing of precipitators, sampling of soot particles, air cleaning, etc.

Authors: Putera Gusti Muhammad Perdana , Suhartrono Eko , Prihatini Nopi Stiyati , Adhani Rosihan , Mahyudin Rizqi Puteri , Iskandar
Published: February 2025

Objective: The aim of this research is to analyze the relationship between the increase in the incidence of periodontal disease and the levels of nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO) in the air of Banjarbaru City.
 
Theoretical Framework: The relocation of the capital from Banjarmasin to Banjarbaru, South Kalimantan can have negative impacts. One of them is the occurrence of air pollution. Air pollution is suspected to be related to the incidence of periodontal disease due to the presence of several pollutants, including NO2, SO2, and CO. However, further studies are needed to examine the relationship between these pollutants and the incidence of periodontal disease.
 
Method: Data on pollutants NO2, SO2, and CO for the years 2021 and 2024 were obtained through spatial analysis using the Google Earth Engine (GEE) application. The data obtained will subsequently be visualized with the help of SURFER Version 23 software. The incidence data of periodontal disease in 2024 was obtained from the Banjarbaru City Health Office. The increase in pollutant levels was analyzed using a paired T-test, and the relationship between pollutants and periodontal disease was analyzed using multiple linear regression.
 
Results and Discussion: The research results showed a significant increase in SO2 and CO levels (P < 0.05). The research results also showed an increase in the incidence of periodontal disease from January to December 2024. An increase of 84.86% in periodontal disease is significantly related to air pollutant levels. The results of the statistical test showed a relationship of R2 = 0.72 (p=0.01; p<0.05). The pollutant that is significantly related to this disease is CO (p=0.00; p<0.05).
 
Research Implications: The results of this study prove that the increase in the incidence of periodontal disease in the city of Banjarbaru is related to the increase in air pollutant levels, particularly CO. The results of this study are expected to serve as a guideline for improving air quality in the city of Banjarbaru.
 
Originality/Value: The results of this study provide a new perspective on the impact of air pollution on dental health. Some previous research results have extensively discussed the relationship between dental and oral diseases and the increase in PM2.5 and PM10, but this research provides a new perspective that CO pollutants can also increase the risk of dental and oral diseases, particularly periodontal diseases.
Rozszczelnienie antropocenu. Nowy zwrot solidarnościowy w edukacji polonistycznej
Authors: Ochwat Magdalena
Published: February 2025

The article presents an attempt to decenter the Anthropocene in Polish language lessons by introducing a new, symbiotic perspective. Using tools from the new humanities, particularly ecocriticism, the author changes the perspective of interpreting selected school readings. She introduces new categories into humanities education, such as "withness," "flat ontology," "relationality," "agency," with "care" for the world being the most important. Care becomes a methodology for reading texts. The article concludes with outlining a new conceptual framework - the Symbiocene, which could replace the previous one, namely the Anthropocene - an era of conquest and consumption would be replaced by good coexistence. The Symbiocene, a community-based life between species based on mutual care, could become the basis for new stories in Polish language lessons.
Doświadczenie szkolnego wyobcowania przez uczniów ze specyficznymi trudnościami w uczeniu się a europejska idea "szkoły dla wszystkich"
Authors: Pomirska Zofia
Published: February 2025

The article deals with the issue of student alienation resulting from specific difficulties in learning to read and write. This psychosocial aspect of the functioning of dyslexic students at school is more and more often perceived as a serious problem with long-term effects, both individual and social. In this context, it seems reasonable to recall the assumptions of inclusive education, which can be an effective remedy against the alienation of students with dyslexia in the school environment.

Jak nie wychować faszysty albo o tym, że nawet "porządni ludzie" stają się nosorożcami
Authors: Kołodziej Piotr
Published: February 2025

The title of the article contains allusions to Georg Ziemer’s book How to Raise a Nazi and Eugène Ionesco’s drama Rhinoceros because the text raises the problem of fascism and the fascination of the modern world: attention is drawn to the symptoms of disturbing processes known from the past, which have been emerging, especially recently, and, similarly to pasts that are ignored and lead to exclusion, violence, hatred and contempt. As an institution with formative functions, school is increasingly anachronistic in its current shape and, by definition, based on coercion rather than freedom, which becomes a significant and endangered place in such a context. Therefore, the author of the text, referring to his own many years of teaching practice, legal conditions (the so-called core curriculum), diverse literature on the subject, literary and philosophical works and the current cultural and social context, point to these threats and, therefore, also to the problem of responsibility of people organising education both at the level of the entire country and in each specific class.
Pierwsze kroki w nauce języka, czyli jak nauczać dzieci z Ukrainy języka polskiego z wykorzystaniem przeznaczonego dla nich "Elementarza"
Authors: Błasiak-Tytuła Marzena
Published: February 2025

The article deals with issues related to planning Polish as a foreign/second language for children and emphasises the need to consider the language level of a child in L2. It is important to select appropriate vocabulary, grammatical structures and prosodic elements, taking into account the subjectivity of a learner as well as the right to form their own personality and self‑actualise according to their needs and interests. The curriculum should be tailored to the communication needs of a child.
An example of this approach is Elementarz [Primer], a reading primer for children from
Ukraine, developed by the FINE Foundation in co‑operation with UNICEF. This primer aims to support teachers and parents who want to help their children learn Polish from scratch. Therefore, each page of Elementarz contains short and simple instructions explaining how to solve a task with the child. The book is designed to encourage the child to engage in various activities – from colouring and cutting to glueing different materials. This approach is based on the author’s belief that physical activity and social interaction are fundamental to the development of a child.

Asset Forfeiture As An Instrument In Fighting Corruption
Authors: Lindasari Lindasari
Published: February 2025

This research employed a normative method to analyze the effectiveness of asset forfeiture in corruption cases, examining relevant laws, legal doctrines, and court decisions. The research addresses two main issues: the effectiveness of asset forfeiture in recovering state losses due to corruption and the factors influencing its success, as well as the challenges encountered in its application as a tool to combat corruption in Indonesia. The findings indicate that while asset forfeiture has the potential to recover state losses, its implementation is hindered by technical and institutional limitations, including the difficulty of establishing a direct link between seized assets and corrupt activities. Key factors influencing the success of asset forfeiture include weak coordination among law enforcement agencies, insufficiently trained personnel, and a lack of transparency in the asset seizure and management process. The primary challenge remains inconsistent law enforcement and weak oversight, which are compounded by legal and political obstacles. To enhance the effectiveness of asset forfeiture, legal reforms and the strengthening of law enforcement agencies, promoting greater synergy and professionalism in the fight against corruption, are essential.
Improved Data-Driven Trajectory Optimization Method Utilizing Deep Trajectory Generation
Authors: Gui Xuhao , Zhang Junfeng , Tang Xinmin , Bao Jie
Published: February 2025

The imbalance between air traffic capacity and demand, especially in the terminal maneuvering area, constrains the development of the civil aviation industry. To enhance the capacity, providing aircraft with optimal trajectories is the way forward. The key challenge of building a trajectory optimization model lies in embedding air traffic controllers’ operation experience into the optimization process. Previous efforts proposed a data-driven trajectory optimization method to learn operation experience from historical data for trajectory optimization use, which is limited by the issues of insufficient quantity and diversity of trajectory data. To solve those issues, an improved model is proposed to further improve the trajectory optimization performance. Firstly, this paper exploited a connecting-based trajectory generation model to generate massive synthetic trajectories. Then, this paper used a data-mining-based valuable trajectory identification technique to find valuable trajectories that can be used to enrich its operation experience. A case study on Guangzhou Baiyun International Airport was conducted to verify the proposed method. The results show that the proposed model successfully incorporates more operation experience during the optimization process. Compared with the benchmark model, the proposed model can adapt to more complex air traffic and provide optimal trajectories for more incoming aircraft.

Published: February 2025

Virtual assistants (VAs) are known to improve performance, reduce mental workload (MWL), and improve situational awareness (SA) in complex cognitive tasks. However, there is a lack of studies focusing on anomaly resolution tasks in time- and safety-critical environments such as long-duration exploration missions. This paper aims to investigate the effects of using a VA, namely Daphne-AT, on crew performance, SA, and MWL in the context of spacecraft anomaly treatment. Participants ([Formula: see text]) were tasked to detect, diagnose, and resolve anomalies in two different but equivalent experimental sessions (five anomalies with the VA and five anomalies without the VA). In each condition, performance was quantified based on the number of anomalies correctly resolved and the total time needed to resolve the anomalies. SA and MWL were quantified using the Situational Awareness Rating Technique and the NASA Task Load index. Results indicate that participants resolved more anomalies in less time during sessions with VA. MWL reduced significantly during sessions with VA. Although total SA did not significantly change between VA conditions, the subscales attentional demand and understanding improved with VA. These findings suggest that VAs are promising decision support tools for anomaly resolution in domains such as spaceflight, aviation, or emergency response.
Enhancing System Model Quality: Evaluation of the Systems Modeling Language (SysML)-Driven Approach in Avionics
Authors: Kausch Hendrik , Pfeiffer Mathias , Raco Deni , Rumpe Bernhard , Schweiger Andreas
Published: February 2025

Quality of software strongly depends on the quality of the models that are used throughout the phases of a development process. Therefore, ensuring model quality is an important aspect that makes a significant contribution to product quality. To determine its contribution to product quality, model quality must be evaluated and demonstrated using suitable indicators. In this paper, the influence of a holistic systems development approach on model quality is evaluated using a use case from the avionics domain. The model artifacts developed in Systems Modeling Language (SysML) version 2 are evaluated in terms of internal, external, and notation quality. A total of 26 indicators are considered to determine model quality. Whereas internal indicators are defined for individual model artifacts, external indicators are defined over multiple model artifacts. Several of the indicators are positively influenced by the expressiveness of the modeling language and the underlying mathematical semantics. Other indicators depend on the methodological guidelines that control the development process. In summary, it can be stated that the application of the presented development approach contributes to high model quality and thus high product quality.

Based on the Kirchhoff–Karman nonlinear theory, the postbuckling bearing capacity (PBC) of perforated plates under shearing load was studied and compared using a self-developed quasi-conforming element program with singular point identification and switching approach. The influences of geometric parameters on the PBC were analyzed. During calculation, the edge beams were introduced to simulate effects of boundary on PBC. The perforated plates were manufactured and tested to verify the accuracy of the numerical results. The results show that the influence of in-plane constraints along the normal of edges on the PBC is more significant. The PBC increases with the increase of plate thickness but is not sensitive to the change of the hole’s location. The reinforcement can reduce the stress concentration and increase the PBC by 7–133%. The PBC is greatly affected by the aperture [Formula: see text], and it is found that the optimal aperture [Formula: see text] exists when the side length [Formula: see text] is constant. The PBC under the optimal aperture is higher than that under other apertures. To facilitate the optimization design, a more refined geometric parameter library is provided by the least-squares method combined with the linear interpolation method. The interpolation results are verified by the existing numerical results.

The formation of a ground vortex at the inlet of a cylindrical nacelle operating in suction near a ground plane in the presence of crosswind is significantly delayed in wind tunnel experiments using aerodynamic bleed. Peripheral bleed actuation of the external airstream is utilized to alter and delay the near-ground flow reversal on the leeward side, which precedes the vortex initiation. It is shown that azimuthally symmetric or asymmetric bleed configurations can significantly delay the ground vortex formation, although at the expense of the decreased total pressure recovery. Utilization of about 21% global porosity over the upper inlet surface can delay the vortex formation to over 300% of the required dimensionless inlet momentum flux in the absence of control. Moreover, the circulation of a ground vortex that eventually forms in the presence of the asymmetric bleed actuation is reduced by nearly 40% compared to the corresponding ground vortex in the absence of control.

A multiscale repeating unit cell model of a single spherulite containing four disparate length scales was developed to predict the thermoelastic behavior of semicrystalline thermoplastic materials for composite aerospace applications. The continuum level scales were fully coupled and modeled using the generalized method of cells and the high-fidelity generalized method of cells micromechanics theories. Data from molecular dynamics simulations were used as inputs for the amorphous and crystalline constituents in the multiscale continuum models. Effective Young’s modulus, shear modulus, Poisson’s ratio, coefficient of thermal expansion, and thermal conductivity were predicted for polyether ether ketone and polyether ketone ketone, showing good agreement with the available experimental data from the open literature. Moreover, it is shown that predicted properties are fairly insensitive to the fidelity of the micromechanics model used at the highest continuum scale or the assumed shape of the spherulite.

This study aimed to explore the perception and usefulness of tourism theory in Brazil. Adopting a quantitative approach based on Stergiou and Airey's model (2018), a survey previously conducted in the UK was adapted. To this end, questionnaires were distributed among members of associations in the field, obtaining 135 responses. The results highlight the relevance of tourism theory in practice, emphasising the need for integration between the two facets to deal with challenges in destination management. In the Brazilian scenario, the importance of this relationship was more solid as compared to the UK context. This finding emphasises that courses in the area should consider the praxis of the social direction of research. Furthermore, it highlights the importance of addressing practical issues to strengthen the epistemic authority of researchers, emphasising that theory should adapt to practice and not practice to theory

This study conducts an analysis of the utilitarian and artistic handicraft work made from clay in the municipality of Ráquira Boyacá, in order to understand the role of tourism in the changes in handicraft practices and their relationship with market dynamics. The methodological horizon was oriented from the qualitative approach and the ethnography of places was used as a method. The information was systematized and analyzed using the qualitative analysis software ATLAS.ti. The findings indicate that artisans have been forced to generate changes and transformations in their traditional crafts, in order to keep up with contemporary trends, which are determined by tourism practices. It is concluded that tourist consumers are determining actors in the production, commercialisation and consumption of Ráquira's artisan work, inasmuch as, from their valuation system, symbols, images and representations, they reconfigure the artisan practices, forcing the artisan to resignify their occupation and, above all, the final artisan piece so that it is articulated to the economic dynamics of the region
‘Grafitización’ vs ‘turistificación’: ¿signos informales de apropiación de la ciudad o desprotección del área histórica no turística?

The historical city centre of Seville, especially its northern sector, is currently suffering the highest level of “graffiti” to which it has ever possibly been subjected. Unlike the southern area of the Old Town, where overtourism has replaced regular residents with temporary visitors, in the northern area of the centre the proliferation of graffiti is notable. This fact affects the local identity of the area's residents and reduces the architectural and urban quality of their surroundings. The presence and increase of these actions make us wonder if they are the result of social appropriation of this area of the city that still resists excess tourism and that citizens continue to recognise as their own. The objective of this research is to assess whether graffiti can serve as an indicator of non-tourist areas of the historical centre. In other words, graffiti can serve as a means whereby to differentiate tourist-saturated areas from residential areas. Through a photographic study and mapping of the affected areas, we identified whether this indicator is evident in those areas of the historical centre that can still be considered predominantly residential. It is remarkable that its presence immateri
Stalin’s “Revolution from Above” or the Radical Etatization of the Early Soviet Rural Society? To Rethink Approaches
Authors: Ignatieva E. A.
Published: February 2025

The concept “revolution from above” as a large-scale socio-political experiment demands a nuanced theoretical understanding. This article examines a model that provides a comprehensive analysis of this experience through the lens of social and humanities sciences. The “revolution from above” was an ambitious project that was realized from a “seeing like a state” perspective. However, it led to destructive consequences for both society and the system as a whole. The study highlights several “traps” encountered during the implementation of “socialist transformations”, such as limited transformations, lack of necessary financial resources, normalization of emergency measures, limited potential, unintended consequences. These factors played a pivotal role in the negative effects observed. To explore the transformation of rural Soviet society at the turn of the 1920s – 1930s, the article proposes a model of radical etatization. It concludes that the “revolution from above” was a natural culmination of the comprehensive process of etatization that had been underway since 1917. The forced and etatization of society during this period was executed by the party state through radical measures in both the political and socio-economic spheres. Consequently, this provoked a corresponding radicalization of positions and actions from rural society. The radical etatization project in rural areas was characterized by significant social conflict between the interests of the party state and those of early Soviet society.This article, which incorporates regional examples, delineates the destructive consequences of such societal transformations.
