Historical and Contemporary Perspectives: Metaphorical Significance of Tooth Extraction in Lithographs and Postcards in the 19th and 20th Centuries in Their Specific Socio-Historical Context.
Authors: Busch Wolfgang
Published: February 2025

In historical illustrations and caricatures, the extraction of a tooth served as a powerful metaphor and threatening gesture that extended far beyond the medical context. This article examines the symbolic significance of this dental procedure and the extracted tooth as an expression of loss, disempowerment, and territorial dispossession. T he comparison covers a wide range of visual representations from the French Revolution (17891799), the French July Revolution (1830), the Crimean War (1853-1856), the Austro-Prussian War (1866), the Franco-Prussian War (1870/71), to the First (1914-1918) and Second (1939-1945) World Wars and places them in their respective historical contexts. In this way, the comparison provides an insight into 150 years of European history in a dense and consecutive time sequence, which ultimately culminated in the great catastrophe of the Second World War. By analyzing lithographs and postcards as propaganda images, the article shows how the act of tooth extraction was used metaphorically to illustrate political and social upheaval. Particular attention is paid to the depiction of tooth loss as a symbol of loss of power and privileges, as an act of humiliation and disenfranchisement, and as a sign of territorial expansion, inevitably at the expense of another country, which thereby loses territory and influence. What happened in terms of political narratives during the period under study, and are there continuities and changes in the use of metaphors and symbols in political propaganda, and what role do emotionalization and simplification play? T he article also discusses ethical issues regarding the responsibility of artists and media creators when using art and symbolism as political tools. The Italian Illustrator Gino Boccasile (19011952) should be given special consideration in this context. This comparative study highlights the enduring power of the illustration of a tooth extraction as a visual and rhetorical device for conveying complex historical and political narratives and emphasizes the relevance of such metaphors in modern political communication.
As Tecnologias Digitais como condição habitativa e o Ensino de Filosofia
Authors: Miranda Junior Gilberto
Published: February 2025

O presente artigo tem por objetivo refletir sobre Filosofia, Tecnologia e Ensino de Filosofia no contexto do impacto das tecnologias digitais na sociedade atual e como isso se relaciona com o ensino de filosofia na escola básica. Ele resulta da pesquisa em desenvolvimento no Mestrado Profissional em Filosofia / PROFFILO. A discussão se desenvolverá sob três interrogações: que tipo de Filosofia deveria ser mobilizada politicamente na escolarização básica para se cumprir o previsto na LDB? De que forma a Tecnologia, enquanto condição habitativa, se insere na experiência social e na formação de nossa subjetividade nos exigindo que reflitamos sobre ela para além do aspecto do ensino profissional em que está inserida? E, por fim, de que forma o Ensino da Filosofia, enquanto campo científico autônomo, pode unir o tipo de Filosofia a ser mobilizada na escola e a compreensão crítica da Tecnologia em seu papel contemporâneo? Se hoje nossa vivência está imbricada com a tecnologia de forma muito mais fundamental que em outras épocas, é papel da Filosofia mobilizar um ensino tal que capacite a sociedade a pensar-se para transformar essa vivência, caso decida, inclusive de forma rebelde, colocando em questão as estruturas que criam, desenvolvem e mantém essa relação que coisifica o ser humano a favor de quem detém o poder sobre essas mesmas estruturas. O presente artigo reflete sobre isso e procura criar condições para a criação coletiva de um consenso de classe, trazendo uma articulação entre diversos pensadores, com maior ênfase para o pensador chinês Yuk Hui.

Published: February 2025

Understanding the dangers of gadget use is an understanding that discusses what is meant by gadgets, as well as the impacts caused by gadgets if they are played with for too long. However, in reality, what often happens is that there are still parents who do not understand the dangers of gadget use in early childhood. So it is necessary to make efforts to improve parents' understanding of the dangers of gadget use in early childhood by providing information services through audio-visual media. The purpose of this study was to determine whether information services using audio-visual media have an effect on improving understanding of the dangers of gadget use in parents of students. The research method used is a qualitative research method with a phenomenological research type. The sample or research informants were 5 parents of students at Hidayatut Tholibin Kindergarten, Bojonegoro. Meanwhile, the data collection techniques used in this study were questionnaires, interviews, observations and documentation. Based on the results of interviews before and after being given information services, it was concluded that all informants understood the dangers of gadget use after providing information services through audio-visual media and applying them to students. So it can be concluded that providing information services through audio-visual media has an effect on increasing the understanding of the dangers of gadget use among parents of students at Hidayatut Tholibin Kindergarten, Bojonegoro

Evaluating the implementation of an integrated work health intervention among cleaners in Denmark: Challenges and lessons learned
Authors: Poulsen Vivian Rueskov , Andersen Astrid Juhl , Mortensen Ole Steen , Streymá Margrethe Bordado , Korshøj Mette
Published: February 2025

Introduction: Work-related diseases and injuries represent a rising global health challenge, with 2.9 million deaths attributed to work-related causes in 2019. Work-related risk factors and diseases are unequally distributed across occupational groups, with cleaners identified as a vulnerable occupational group. Integrated approaches combining the prevention of disease and promotion of health in work health interventions have been developed. This process evaluation aims to assess the implementation of the Integrated Approach to Health, Wellbeing, and Productivity at Work (ITASPA) intervention. Methods: The ITASPA intervention was implemented at two workplaces among cleaners in Denmark. At each workplace, a committee of employees and line managers was formed to develop initiatives to prevent work-related injuries and diseases and promote workers’ health, safety, and well-being. Using the British Medical Research Council’s framework, this process evaluation assessed the implementation through reach, dose, fidelity, adaptations, mechanisms of impact, and contextual factors. Data from focus group interviews and field notes were utilized to evaluate the implementation. Results: A total of 91 cleaners provided data, and three workshops were held at each workplace. Lack of information about the intervention and motivation challenged the implementation. Furthermore, unwanted power dynamics were unintended consequences of the intervention. Contextual factors, such as many replacements, time pressure, and the absence of managers, challenged the implementation and fidelity. Conclusion: Integrated approaches to work health interventions among employees with short or no education can positively impact employees’ health, well-being, and safety if comprehensively implemented. However, attention should be given to unintended power dynamics arising from participatory approaches and the importance of management during implementation. Future interventions may benefit from increased attention to such factors to enhance long-term sustainability as well as realist evaluation approaches for more comprehensive evaluations of contextual factors. Trial registration: ITASPA was retrospectively registered at Clinicaltrials.gov on the 19 May 2023 (NCT05866978).

The study examined the use of time series models to forecast cement prices at the Al-Marqab Cement Plant in Libya, focusing on predicting cement prices for eight months during the year 2024. The study relied on monthly data spanning from 2021 to 2023.
The results showed that the price series was stable at the second-order difference, as confirmed by the Dickey-Fuller test, which indicated the need for this transformation. After evaluating the proposed models, the study concluded that the ARIMA (1,2,0) model was the most suitable for forecasting cement prices. Evaluation criteria such as Mean Squared Error (MSE) and Mean Absolute Error (MAE) were used to compare the models.
Since the results provide accurate forecasts of cement prices, they enable the plant management to make informed decisions regarding production and pricing in the upcoming period. The study recommends using these findings for production planning and pricing strategies. Additionally, future studies could expand the scope of research to include additional economic factors that may influence cement prices.

Covariance Estimation Of Millimeter Wave Channels Using Sparse Signal Recovery Algorithms In A Hybrid MIMO Architecture
Authors: Şenyuva Rıfat Volkan
Published: February 2025

In this paper, the channel covariance estimation of a single mobile station (MS) in a narrowband millimeter wave (mmWave) communication system was addressed. The communication system worked in time division duplex (TDD) mode and the channel covariance was estimated in the uplink communication. The base station (BS) had multiple antennas with a hybrid architecture of radio frequency (RF) chains made up of analog and digital combiners, while the MS had a single antenna. The investigated system model assumed the shared combining matrix scheme where the same combining matrix was used across multiple coherence blocks of the mmWave channel. The application of the sparse signal recovery algorithms including the simultaneous orthogonal matching pursuit (SOMP), the multiple response sparse Bayesian learning (MSBL), and the correlated sparse Bayesian learning (CSBL) to the system model were shown. The algorithms were evaluated numerically, and their normalized mean square error (NMSE) performances were compared against the benchmark oracle minimum mean square error (MMSE) estimator in multiple scenarios of varying number of RF chains at the BS and sparsity ratios for modeling the mmWave channel. The numerical results indicated that the CSBL algorithm provided the NMSE results closest to that of the oracle MMSE estimator in all the scenarios.
Investigation of Fragmentation and Abrasion Resistance of Basalt and Limestone Aggregates in Bitlis Region and the Relationship between MgSO4 and Flatness Index Values
Authors: Akıllı El Alev
Published: February 2025

The mechanical characteristics of aggregates have a direct impact on the performance of asphalt mixtures. The aggregates used in road construction must possess certain essential qualities; they should be clean, hard, durable, resistant to abrasion, of uniform quality, and free from harmful substances. Resistance to abrasion is a very important property in engineering fields involving the use of aggregates. The Los Angeles fragmentation and Micro-Deval abrasion tests are among the most commonly used mechanical tests to assess the performance characteristics of aggregates in terms of abrasion and fragmentation. This study examined the abrasion and fragmentation resistance, flatness index, and frost resistance of both basalt and limestone aggregates. The study also evaluated parameters within the Los Angeles and Micro-Deval test processes. Based on the test results, it was concluded that the Micro-Deval abrasion test exhibited a more consistent relationship with other physical and strength properties of the aggregates. Moreover, the Micro-Deval test provided more realistic values for assessing the fragmentation resistance of the aggregates. Additionally, it was concluded that the steel balls employed in the Los Angeles test did not accurately represent the true impact of the internal properties of the aggregates on the disintegration process.

Authors: Türk Mahmut , Haydaroglu Cem , Kılıç Heybet
Published: February 2025

This study focuses on the serious sustainability and reliability problem caused by non-technical losses (NTL) due to energy theft in electrical grid systems. In order to reduce these losses, we propose an artificial intelligence-based approach that utilizes deep learning architectures in the detection of different types of leakage (voltage leakage, current leakage and voltage-current leakage). Unlike the studies in the literature, the data set is converted into two-dimensional matrices and analyzed with today's popular approaches, Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) models; CNN surpassed LSTM's 64.17% accuracy rate with 97.50% accuracy rate. In addition, from the classical methods, 67.5 accuracy rate was obtained with the k-Nearest Neighbor (k-NN) method and 62.25 accuracy rate was obtained with the Support Vector Machines (SVM) method. Comparisons with such traditional methods have revealed the superiority of CNN in determining complex leakage patterns. The findings highlight the potential of CNN to be used as a reliable tool for real-time theft detection by integrating it into smart grid systems. Future research will aim to further increase the scalability and effectiveness of this solution by examining the integration of real-time data and hybrid model approaches.
Predicting Three-Dimensional (3D) Printing Product Quality with Machine Learning-Based Regression Methods
Authors: Tatar Ahmet Burak
Published: February 2025

This study examines how printing parameters affect the roughness, tensile strength, and elongation of 3D-printed parts used in various applications. Machine learning-based regression models were employed to optimize product quality. The open-source "3D Printer Material Requirement" dataset obtained from the Kaggle platform was utilized to predict product quality. This dataset includes input parameters such as layer height, wall thickness, infill density, infill pattern, nozzle temperature, bed temperature, print speed, printing material (PLA and ABS), and fan speed. These parameters were analyzed for their impact on the product's roughness, load resistance, and elongation under tensile force. Based on these evaluations, product quality was estimated according to its intended use. Parameters such as layer height, wall thickness, infill density, infill pattern, nozzle temperature, bed temperature, print speed, printing material, and fan speed were identified as key factors influencing output performance. Within this framework, prediction models including Linear Regression (LR), Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM), Gaussian Process Regression (GPR), and Multi-Layer Perceptron (MLP) were developed, and their performances were assessed using metrics such as accuracy (R²), error rates (RMSE, MSE, MAE), and computational time. Among these methods, GPR demonstrated the highest prediction accuracy for elongation, tensile strength, and roughness, with respective values of 0.98, 0.9, and 1. The findings indicate that machine learning applications are effective tools for quality prediction and optimization in the production processes of 3D printers. Furthermore, this study provides a novel perspective on quality control and design optimization in 3D printing processes.
CALF-GAN: Multi-scale convolutional attention for latent feature-guided cross-modality MR image synthesis
Authors: Zhu Xinmiao , Wang Yuan
Published: February 2025

Multimodal medical image synthesis plays a crucial supportive role in research within the field of biomechanics, providing high-precision data and analytical methods for studies on anatomical structures, tissue characteristics, and mechanical modeling. However, due to practical constraints, certain modalities of medical images may be difficult to obtain, posing challenges for model training and high-accuracy biomechanical research. Existing methods employ convolutional neural network (CNN)-based generative adversarial models to synthesize missing modality information across modalities. However, CNNs are limited in their ability to model long-range dependencies. Transformers offer a new paradigm to address these limitations, yet their high computational and memory demands remain a significant drawback. To tackle these challenges, we propose a novel generative adversarial model, termed the Convolutional Attention Latent Feature GAN (CALF-GAN), which leverages multi-scale convolutional attention for cross-modal medical image synthesis. A dedicated latent attribute separation module is employed to disentangle modality-specific features between source and target modality images, enhancing the synthesis of medical semantics, such as pixel intensity values. Furthermore, to improve the model’s capacity for long-range dependency modeling while reducing computational overhead, we design a generation module based on multi-scale convolutional attention, capturing long-range dependencies using only convolutional operations. Extensive experiments conducted on various medical image datasets demonstrate that CALF-GAN achieves remarkable generalizability and outstanding overall performance under low memory requirements, making it well-suited for application in high-precision biomechanics research.

Published: February 2025

The Covid-19 pandemic has profoundly impacted the education sector, especially teachers' psychological well-being. This study investigates anxiety, adaptability, and barriers to help-seeking behaviors among 468 Central Luzon teachers from state universities and colleges (SUCs). It also examines the relationships among these variables. Using a mixed-methods approach, quantitative data were gathered through an online survey, while qualitative insights were obtained from a virtual focus group discussion with seven participants. Results indicate that teachers experienced high anxiety levels (M=3.59), driven by health concerns, technology-related challenges, and transportation issues. Despite these stressors, their adaptability to work was also high (M=3.6), supported by coping strategies such as self-care, seeking support, and acceptance. However, moderate barriers to seeking professional help (M=3.0) were identified, linked to self-reliance, social stigma, and faith. The study further reveals that difficulties in seeking mental health support are associated with lower adaptability at work. These findings emphasize the importance of promoting self-care practices and resilience-building initiatives for SUC faculty during and beyond the pandemic.

Competencia, reforma de la regulación, privatización y competitividad
Authors:   Tribunal de Defensa de la Competencia, Petitbò Juan Amadeo
Published: February 2025

Los países industrializados han sido testigos de un proceso ininterrumpido de internacionalización de sus empresas y globalización de sus mercados y han iniciado la andadura de la liberalización económica y la privatización. Este movimiento ha ido acompañado de la extensión de la cultura de la competencia como reacción al exceso de intervencionismo y regulación ineficiente que han soportado sus economías durante muchos años y a los efectos de dicho intervencionismo sobre las empresas, los trabajadores y el propio sector público. No hay duda de los efectos positivos de la competencia sobre los precios, la oferta, la inversión, la ocupación y, en consecuencia, el crecimiento económico. Por estas razones, no sin dificultad, las políticas de introducción y defensa de la competencia y desregulación, han ganado importancia en los últimos años. Se trata de combinar, con las proporciones adecuadas, competencia, regulación, defensa de los intereses públicos y bienestar.
Servicio público y servicio universal en las telecomunicaciones
Authors:   Asesores Jurídicos Agrupados, S.L., Ariño Ortiz Gaspar , de la Cuétara Martínez Juan Miguel ,   Asesores Jurídicos Agrupados, S.L.
Published: February 2025

Se plantea la revisión del concepto jurídico de servicio público que aparece consagrado en el art. 128 de la Constitución. En la práctica éste ha quedado desplazado por el art. 90.2 del Tratado de Roma que impone la aplicación de las normas sobre la competencia en la medida en que éstas no impidan, de hecho o de derecho, el cumplimiento de la misión de servicio público de que se trate. Ello supone la desintegración vertical de estos sectores y la distinción en ellos de lo que es servicio público y de lo que no lo es. El concepto de reserva al sector público queda sustituido por la idea de servicio universal, que ha alcanzado un desarrollo muy preciso en el campo de las telecomunicaciones, en el que la Unión Europea ha realizado una de las formulaciones más completas del mismo. Dicho servicio se basa en los principios de universalidad, igualdad y continuidad a fin de permitir el acceso al mismo, con un nivel de calidad determinada, a todos los usuarios, independientemente de su situación geográfica y a un precio asequible.

La inacabada transformación del comercio vasco
Authors:   Gobierno Vasco, Gorospe Félix
Published: February 2025

La actividad comercial no recibe la atención y el reconocimiento que han tenido otros sectores de la economía, y que han pasado también por momentos de profunda transformación como en los que se encuentra este sector. Estos profundos cambios, todavía inacabados en el País Vasco, conducirán al sector a situarse como una actividad preponderante dentro del conjunto de la economía, y a sus empresas a los lugares principales del ranking empresarial. Uno de los elementos objeto de debate es el grado y el tipo de intervención pública que se requiere para impulsar su adaptación. Abordar una auténtica reforma, que es lo que este sector espera y necesita, significa actuar más allá que a través de la legislación exclusivamente, con un papel de liderazgo y desde una instancia con competencias superiores a las dispuestas desde las Comunidades Autónomas.
Reconfigurações nos direitos territoriais de indígenas, quilombolas e outras comunidades tradicionais: as repercussões internas dos padrões internacionais de proteção
Authors: Ribeiro Inafran
Published: February 2025

Este artigo analisa as relações entre padrões internacionais de proteção aos direitos humanos e os direitos territoriais de povos indígenas, quilombolas e outras comunidades tradicionais no Brasil. Realizou-se uma pesquisa documental e bibliográfica, e analisou-se o material com base na abordagem construtivista, a qual, nos estudos sobre direitos humanos, evidencia os papéis desempenhados por múltiplos atores nacionais e transnacionais nos processos de reconhecimento e efetivação de direitos. Argumenta-se que as reconfigurações internas observadas nos direitos territoriais foram influenciadas pela dinâmica de produção e reavaliação de padrões normativos internacionais, por meio da circulação de ideias entre organismos internacionais, agentes de Estado, ativistas, intelectuais e movimentos dedicados às causas indígena, étnico-racial e socioambiental. Como efeito da socialização de normas e perspectivas teóricas, ocorre o rompimento formal do sistema jurídico nacional com o paradigma integracionista e a criação e ressemantização de categorias teóricas e político-normativas, ampliando o rol de grupos titulares de direitos territoriais específicos

This article explains Indonesia's golden opportunity as the host of the G20 Presidents event in 2021-2022 and the benefits and great opportunities for Indonesia in the tourism sector. This study uses a qualitative method with a literature study approach. The G20 is a cooperation forum consisting of 20 countries formed to discuss financial and non-financial issues such as anti-corruption, digitalization, and women's empowerment. The existence of this forum itself is very important for each member country, including Indonesia as one of the members of the G20 Presidents. Thus, the holding of the G20 Presidents forum in Indonesia is a great opportunity for the Indonesian nation to introduce Indonesia as widely as possible to other nations. Especially in the tourism sector, with the hope of showing the world that Indonesia is a nation that is very rich in various resources. So that it can be a great opportunity for Indonesia to cooperate with other countries for the benefit of its own country in the economic aspect after the Covid-19 pandemic.

Authors: Nurlaili Lutvi Dwi
Published: February 2025

This study aims to explain the transmigration process of the Balinese Hindu community in Seputuh Raman, Central Lampung. This study uses a descriptive narrative method where the data is explained narratively without conducting in-depth analysis. Lampung Province is one of the provinces in Indonesia that is a destination for transmigration. It is also a province founded by various tribes, one of which is the Balinese community. Transmigration is an effort to develop a region that has been implemented since the era of regional autonomy, to develop new areas and reduce poverty. However, in the era of regional autonomy, transmigration must be adjusted to the characteristics and specific conditions of the region. The transmigration program is said to be successful because of the findings that mention the success of the Balinese community in building a life in Lampung since they first arrived in Lampung.

Published: February 2025

Background and Objectives: Thyroid is a butterfly shaped endocrine gland responsible for the regulation of body metabolism. Ultrasound is widely used for the detection of thyroid incidentaloma. Methodology: This study was conducted as a descriptive cross-sectional study among patients attending ultrasound clinics in Azadi hospitals and outpatient sonographic clinics for the assessment of the thyroid. A total 200 patients were enrolled. SPSS was used for the data analysis and a p-value of 0.05 was used as the level of significance. Results: Only 75 cases of incidentalomas were identified on sonographic assessment, others had a normal sonography; the prevalence of incidentaloma 37.5%. The majority of the incidentaloma were identified in females (84%) compared to males (16%). Around 2.7% had past history of radiation exposure. And only 2 out of the 75 cases were identified to have malignant potentials. Conclusion: Thyroid incidentaloma is reported to be a prevalent finding in literatures, similar results were seen in our study with a prevalence of 37.5%. Screening for incidentaloma using sonography can be beneficial for the early detection of incidental thyroid carcinomas as the incidence is raising overtime
