Published: January 2025

This study aims to determine the perspective of applying Pancasila values to Elementary School Teacher Education Students of the Muhammadiyah University of Surakarta. In the current era of open life, people's lives are colored by life patterns that are not always in line with the values contained in Pancasila. To counteract the negative impacts of the globalization era, awareness is needed to apply Pancasila values in every aspect of life. This study uses a qualitative method with a phenomenological approach based on subjective or phenomenological experiences experienced by individuals. The study results show that almost all students understand what Pancasila is. Then, in one of the questions asked regarding students' understanding of Pancasila and its contents, several sources have different opinions. This condition happens due to differences in perspective or the portion of one's assessment of others. It also shows that elementary school teacher education students at Muhammadiyah University of Surakarta know Pancasila. However, not all of them understand and properly apply the values of Pancasila in their daily lives.

Hacia una emancipación sin Dios moral
Authors: Berríos Guajardo Víctor
Published: January 2025

En este trabajo se presentan la autonomía de la moral de Kant y la "muerte de Dios" de Nietzsche como parte de un mismo proceso. La autonomía de la moral afirma que el hombre ya no necesita de un motivo externo a su voluntad para actuar moralmente. Nietzsche con la llamada "muerte de Dios", radicaliza esta tesis, en la idea de liberar al hombre de realidades supraterrenales. Así, se constituye un hombre que sufre por la pérdida de su referente vital, pero que al mismo tiempo le abre posibilidades de creación de nuevos sentidos, tan urgentes para el hombre actual.
Giro lingüístico/giro hermenéutico/ giro semiológico
Authors: Rojas Osorio Carlos
Published: January 2025

Diversas filosofías contemporáneas reclaman haber dado el giro lingüístico de la filosofía. La expresión "giro lingüístico" es de Richard Rorty, pero con distintos nombres diferentes autores se han referido al mismo fenómeno ruptural. Michel Foucault invoca a Nietzsche como el autor que ganó para el siglo XX el lenguaje como punto de partida del filosofar. Lyotard, en cambio, atribuye a Wittgenstein dicho viraje. Los estructuralistas invocan a Ferdinand de Saussure como el inspirador de toda comprensión del lenguaje que se desarrolla a lo largo del siglo XX. Pero esta investigación mostrará otros hitos decisivos tanto modernos como antiguos en los cuales se hizo del lenguaje el ámbito preferido del pensar y del filosofar.
El Nacimiento de la tragedia como crítica a la ciencia
Authors: Carrasco Pirard Eduardo
Published: January 2025

El artículo intenta mostrar que El nacimiento de la tragedia de. F. Nietzsche, de acuerdo con las indicaciones de su propio autor, debiera ser también encarado como una crítica de las ciencias. Encarado de este modo, el fin de la tragedia es una misma cosa que el nacimiento de la ciencia. Con lo cual se muestra la oposición existente entre arte y ciencia y el carácter ilusorio de la empresa científica cuando ella se piensa sin su complementariedad con el arte. La posibilidad de un conocimiento trágico en el que se produzca esta síntesis debería venir con el reconocimiento de la ciencia de sus propios límites. Con ello podría abrirse también la posibilidad de una reviviscencia de la tragedia, esto es, la posibilidad de un acercamiento del ser humano a la verdad de su condición de finitud.

Ciencias naturales y ciencias humanas: en busca del sentido
Authors: Reyes José Luis
Published: January 2025

El estatus de las humanidades frente a las ciencias naturales constituye un viejo pero persistente problema epistemológico. Un problema que hunde sus raíces en la también tradicional distinción entre naturaleza y cultura. Acudiendo a los últimos conocimientos entregados por la ciencia contemporánea, este trabajo se propone mostrar que las fronteras entre estas disciplinas y esos dos órdenes de
realidad se han desdibujado. La búsqueda de leyes en las ciencias naturales y de lo histórico o único para las humanidades, son los principales criterios que aquí se examinan.
Sobre el significado subjetivo de la probabilidad
Authors: Finetti Bruno de
Published: January 2025

Se explica cómo es posible introducir el concepto de probabilidad con todo rigor y demostrar las propiedades fundamentales bien conocidas del mismo, ateniéndose exclusivamente al punto de vista subjetivo. Tras haber indicado un procedimiento de carácter cuantitativo que se presta particularmente al tratamiento analítico, se analizan críticamente sus principios, demostrando que son de naturaleza puramente cualitativa y elemental.
El concepto de tiempo en la filosofía real de Hegel de 1805/6
Authors: Meyer Luisa H.
Published: January 2025

En el artículo, la autora lleva a cabo un análisis exegético del texto de la primera parte de la Filosofía Real (1805/6), la Filosofía de la Naturaleza (Mecánica),
donde Hegel tematiza el concepto de tiempo. Y constata que éste, en una primera consideración, aparece como "devenir observado" y es descripto, en cuanto tal, casi en los mismos términos que usa Aristóteles en la Física (IV). Pero en un segundo nivel de consideración, Hegel afirma que, lo que atribuimos al tiempo tenemos que atribuirlo, en realidad, a nuestro modo de intuir o "a la pura ipseidad del ser-para-sí", en un lenguaje que pone de manifiesto la presencia del pensamiento trascendental de Kant y de Fichte. A partir de lo que la autora constata en la Filosofía de la Naturaleza de 1805/6, concluye que una hermenéutica del problema del tiempo en Hegel exige una exégesis detallada del/los textos correspondientes cada vez y la delimitación de los ámbitos temáticos respectivos.El concepto de tiempo expuesto en la Filoso.fía de la naturaleza y toda la problemática implicada difiere en mucho de la que surge de la concepción de la necesaria historicidad del espíritu, por ejemplo. Por eso, concluye que partir, a priori, de una teoría única y unitaria del tiempo por parte de Hegel, sin llevar a cabo dicha exégesis, puede conducir a resultados hermenéuticos apresurados.
Ensayo sobre la "accidentalidad"
Authors: Carrasco Pirard Eduardo
Published: January 2025

Partiendo de la descripción de las condiciones de posibilidad del cálculo de probabilidades, se descubre lo Incalculable como reverso de lo calculable. Este descubrimiento negativo conduce a la descripción de la "accidentalidad", entendida como la entendió Matta, como circunstancia esencial en que se desenvuelve nuestra existencia. Ésta, a su vez, nos sugiere el ejercicio de un pensamiento positivo de lo Incalculable, cuyos orígenes encontramos en la tragedia y en la mitología griega. Finalmente, se exponen dos ejemplosde este mismo pensamiento en un texto de Nietzsche y en una frase de Mallarmé.
¿Quién Habla en la conciencia: Dios, el hombre o el ser?
Authors: Holzapfel Cristóbal
Published: January 2025

El examen que se emprende del fenómeno de la conciencia resulta revelador para la historia de la ética, partiendo por el mundo griego, en el que la conciencia queda testimoniada en distintas experiencias como la del daimon socrático, o las erinias que se convierten en euménides. Es además revelador para la historia de la ética que así como hay una ética heteronómica de la conciencia, y lo mismo cabe decir de la ética autonómica kantiana, asociada a una conciencia también autonómica. Y si en Fichte se llega a concebir la conciencia de la manera más elevada, como el "oráculo del mundo espiritual", es natural que después de él venga un momento de escepticismo tanto respecto del poder de la conciencia, como incluso de su existencia; éste es el caso de Schopenhauer. Probablemente en la misma línea de una toma de distancia del fenómeno de la conciencia, se presenta ella originalmente en Nietzsche en su análisis genealógico como "mala conciencia". Finalmente, en Heidegger la conciencia es en la medida de un "querer-tener-conciencia" y no más como una supuesta facultad en nosotros. Además, ella no dice nada, no comunica deberes, sino que su hablar es silente. Lo más esencial, el ser-sí-mismo al que llama la conciencia, no puede ser sino inefable.
Heidegger y el cristianismo
Authors: Carrasco Pirard Eduardo
Published: January 2025

El propósito de este trabajo es extraer las conclusiones que resultan del pensamiento de Heidegger de la historia del ser para establecer un ordenamiento en épocas de lo que comúnmente se llama "historia de la filosofía". Esto hace posible abordar el tema de la ubicación que ocupa el cristianismo dentro de este esquema, lo cual, por su parte, ayuda a comprender la confrontación entre filosofía y cristianismo que resulta de la particular interpretación de Heidegger sobre el rol que juega este movimiento religioso en la historia de Occidente y ayuda también a establecer de qué manera la superación (ir más allá) de la metafísica constituye necesariamente una superación del cristianismo.

Authors: Olejniczak Teresa
Published: January 2025

The resistance of Candida albicans and other pathogenic yeasts to azole antifungal drugs has increased rapidly in recent years and is a significant problem in clinical therapy. The current state of pharmacological knowledge precludes the withdrawal of azole drugs, as no other active substances have yet been developed that could effectively replace them. Therefore, one of the anti-yeast strategies may be therapies that can rely on the synergistic action of natural compounds and azoles, limiting the use of azole drugs against candidiasis. Synergy assays perperformed in vitro were used to assess drug interactions Fractional Inhibitory Concentration Index. The synergistic effect of fluconazole (1) and three synthetic lactones identical to those naturally occurring in celery plants—3-n-butylphthalide (2), 3-n- butylidenephthalide (3), 3-n-butyl-4,5,6,7-tetrahydrophthalide (4)—against Candida albicans ATCC 10231, C. albicans ATCC 2091, and C. guilliermondii KKP 3390 was compared with the performance of the individual compounds separately. MIC90 (the amount of fungistatic substance (in μg/mL) inhibiting yeast growth by 90%) was determined as 5.96–6.25 μg/mL for fluconazole (1) and 92–150 μg/mL for lactones 2–4. With the simultaneous administration of fluconazole (1) and one of the lactones 2–4, it was found that they act synergistically, and to achieve the same effect it is sufficient to use 0.58–6.73 μg/mL fluconazole (1) and 1.26–20.18 μg/mL of lactones 2–4. Based on biological research, the influence of the structure on the fungistatic activity and the synergistic effect were determined.
POLON, JEGO CHEMIA I TAJEMNICE: 125 ROCZNICA JEGO ODKRYCIA
Authors: Skwarzec Bogdan
Published: January 2025

The paper is of a review character and in historical terms, it contains an overview of research on polonium from the time of its discovery in 1898 (125 years ago) to the present time. The article contains a description of the state of knowledge about the chemistry of polonium, taking into account its physicochemical properties, as well as methods of its production and the radioactivity of its isotopes, as well as its current scientific and industrial applications. The issue of strong radiotoxicity of polonium and the dangers associated with research on it, as well as numerous example of diseases and death from its absorption into the human body, are described in detail. Despite the passage of 125 years since the discovery of polonium, it still fascinates researchers with its mysteries that have not been fully understood, revealed and explained. The sources of this peculiarity should be sought in the fact that although it is classified as a metal, it also has non-metallic properties and can form a number of different chemical compounds. Several chemical compounds of polonium have been tested, which are very easy to get into the human body, where it causes terrible havoc. Alpha particles emitted from decay of 210Po can cause damage to proteins and DNA that load to cell death or such changes in the body that consequently initiate the development of cancer. So you could say that polonium not only has a rich past, but also has an undeniably interesting future
PRZYRZĄDY POMIAROWE PIOTRA CURIE I ICH ZNACZENIE DLA BADAŃ NAD PROMIENIOTWÓRCZOŚCIĄ
Authors: Chrząstowski Piotr
Published: January 2025

This paper describes the instrumentation developed by Pierre Curie in the 1880s to perform very precise measurements of electric charge and very small currents. This system, developed 150 years ago, was almost as precise as most present digital electronic charge measurement apparatuses. Maria Skłodowska-Curie used the same Curie quartz-electrometric system during her research from the selection of the research subject to the final discoveries. The main experimental difficulties regarding the measurement of picoampere leakage currents generated by radioactive rays were presented. It was emphasized that the availability for Marie Curie of a precise ready-to-use electrostatic measurement technique played an important, if not decisive, part in her career and her research. A more general issue addressed here is that laboratory techniques are not only a prerequisite of modern scientific work, but in a great part influence knowledge production

Published: January 2025

When Marie Skłodowska-Curie began research on the radiation of uranium compounds discovered by Henri Becquerel, she uncovered two new chemical elements, sparking a revolution in atomic science. From the very beginning, radium was hailed as a miraculous element; its salts emitted heat, colored porcelain and glass, and emitted a unique glow. Radium quickly found applications in medicine, where it was not only used to treat diseases but also employed in „mild radium therapy” for preventive purposes. Radium, however, possessed not only healing properties but also purported to have the ability to beautify, rejuvenate, prevent, and captivate. A global „radium fever” ensued, leading to the addition of radioactive salts to almost all everyday products. The stories of the „radium girls” and golfer Eben Byers, however, cast a shadow over the fame of radium.

Published: January 2025

albutamol is a short acting, selective beta-2 adrenergic receptor agonist used to treat asthma, bronchitis, as well as prevent exercise induced bronchospasms. Although it is a small molecule, it has considerable conformational freedom. It has four polar groups (-OH and -NH) that can form a variety of intramolecular hydrogen bonds that stabilize individual conformations. It is well known, that such a intramolecular interactions greatly impact molecular properties, because the bioactive conformation of a given ligand could be stabilized by intramolecular hydrogen bonds. The aim of our research is to determine the preferred conformation of salbutamol, and to characterize the intramolecular interactions that stabilize its various conformers, both in a gas phase and in water modeled as a continuous dielectric. The analysis was carried out by B3LYP-D3 and MP2 methods with the 6- 311++G(d,p) basis set. The relative energies and geometrical parameters of intramolecular H-bonds are presented for six selected salbutamol conformers. Moreover, calculated monohydrates of lowest energy salbutamol conformer allow to estimate the interaction energy with water molecule and geometrical parameters of preferred complexes

Palladium is an investment metal that occurs extremely rarely, yet demand for this metal grows each year. Due to its unique properties, it plays a crucial role in many industrial sectors and everyday life. It is widely used in the automotive industry for catalytic converters, in the electronics sector for integrated circuits, in the energy sector as an electrode material in fuel cells, and for energy storage (hydrogen). Among many methods of obtaining palladium materials, electrochemistry holds great potential. By selecting appropriate parameters of electrodeposition process, it is possible to obtain palladium materials with specific chemical compositions (single-, binary-, or ternary-phase) in the form of layers or nanostructures with defined geometries (shape and size). The energy efficiency and catalytic performance of the obtained palladium materials can be enhanced by using suitable carriers with high conductivity, chemical and mechanical stability, and large surface area. Since the breakthrough announcement of cold fusion using palladium by Fleischmann and Pons, interest in palladium has increased significantly, and research on palladium-based materials continues to be extensive. The aim of this article is to discuss the properties of palladium, review research on the electrodeposition of palladium materials, and highlight selected applications (such as in fuel cells and hydrogen production and storage). Additionally, future research perspectives related to palladium will be outlined

Published: January 2025

As cybercriminals become their tactics, phishing URLs are increasingly operated to exploit unsuspecting users. This leads to notable financial loss and erodes user trust in online systems, influencing businesses and individuals. Though effective in specific scenarios, traditional signature-based and heuristic methods often require help keeping pace with the dynamic of phishing schemes. In this study, we introduce a hybrid model combining Gated Recurrent Unit (GRU) and Convolutional Neural Networks (CNN) to enhance phishing URL detection. Our primary purpose was to utilize both temporal feature extraction through GRU and spatial feature extraction using CNN, building a robust model capable of effectively identifying phishing attempts. We evaluated three models, GRU, CNN, and the proposed GRU+CNN hybrid, employing a Kaggle dataset containing over 2.5 million URL samples labeled as phishing. The GRU model reached 97.8% accuracy, while the CNN model performed slightly better, with 98% accuracy. However, the hybrid GRU+CNN model outperformed, achieving an accuracy of 99.0%, showing its superiority in addressing the complexities of phishing detection. Future work will optimize the hybrid model for real-time detection and investigate its adaptability to other cybersecurity domains, such as malware and social engineering threats.

Published: January 2025

Maintaining both rider safety and vehicle dependability on motorbikes requires accurate problem detection. Using an improved ResNet architecture with Improved Sea Fish Optimization (ISFO) and Deep Convolutional Neural Networks (CNNs), this research proposes a sophisticated method for auditory defect identification in motorbikes. The machine ears start by gathering a wide range of audio frequency-based signal datasets from motorbike that span a range of failure scenarios and operational settings. To eliminate noise and identify distinguishing characteristics, these signals go through preprocessing. Then, to extract high-level features from the pre-processed signals, an improved ResNet architecture is used, supplemented with ISFO. By integrating both local and global information, the ResNet architecture's inclusion of ISFO makes it easier to iteratively update feature representations. To further improve the feature representations' discriminative power, Deep CNNs are used. The real-time defect detection system is designed specifically for motorbike uses the learned model. The trained model is used to interpret incoming acoustic data from motorcycle operations. This allows for the identification and categorization of various issues, such as engine misfires, irregularities in the valves, wear on the bearings, and clutch bearing failures. Experiments show that the proposed method is a good fit for precisely categorizing motorbike issues. Analyses conducted in comparison with baseline models demonstrate the superiority of the ResNet-ISFO and Deep CNN technique, demonstrating its resilience and efficiency across a range of fault situations and operational conditions. Overall, the proposed acoustic problem detection system is a potential approach for improving maintenance procedures while also assuring the safety and dependability of automobile engine. Its incorporation into standard maintenance operations can aid in proactive defect identification, reducing downtime and improving vehicle performance.

However, there will be times when supply and demand are out of sync. One of the most difficult and time-consuming tasks in increasing agricultural output is managing and maintaining human and financial resources. In terms of increasing food production, managing resources, and manpower, smart agriculture is the way to go. to develop an IoT system for identifying crop diseases at a finer grain size by combining IoT with deep learning. This technology has the capability to identify agricultural diseases autonomously and provide farmers with diagnostic data. The research suggests a model for fine-grained disease diagnosis in the system called an attention-based convolution neural network with bidirectional long short-term memory (ACNN-BLSTM). The suggested approach incorporates a compensation layer that use a compensation algorithm to combine the outcomes of multidimensional recognition. It does this by first identifying in three dimensions: species, coarse-grained disease, besides fine-grained disease. The ACNN-BLSTM model's hyperparameters are fine-tuned using a hybrid approach called SA-GSO, which combines simulated annealing with glowworm swarm optimisation. This improves the model's detection performance. In comparison to other well-known deep learning representations, the studies demonstrate that the suggested neural network outperforms them in terms of recognition effect and usefulness for teaching real-world agricultural production tasks.
Integrating Homomorphic Encryption with Blockchain for Privacy Preserving Communication on the Internet of Vehicles

Published: January 2025

The Internet of Vehicles (IoV) has emerged as a transformative technology, enabling seamless communication among vehicles and infrastructure to improve road safety, traffic efficiency, and passenger comfort. However, the pervasive collection and exchange of data in IoV environments raise significant privacy concerns, as sensitive information about vehicle locations, driving patterns, and personal preferences may be exposed to unauthorized parties. To address these challenges, this study proposes a novel approach that integrates homomorphic encryption with blockchain to ensure privacy-preserving communication in IoV networks. IoV networks rely on the continuous exchange of data among vehicles, roadside units, and centralized servers to support various applications, including traffic management, navigation, and emergency services. However, the centralized nature of traditional communication architectures poses inherent privacy risks, as sensitive data may be vulnerable to interception, tampering, or unauthorized access. Data integrity was ensured through blockchain storage, with an observed tamper-proof rate of 99.9%, effectively preventing unauthorized access or manipulation of exchanged messages. Despite the additional computational overhead introduced by homomorphic encryption and blockchain operations, our system maintained efficient communication capabilities, achieving an average latency of 50 milliseconds and a throughput of 1000 messages per second. Moreover, scalability was demonstrated as our framework seamlessly accommodated an increasing number of vehicles and communication nodes, with observed linear scalability up to 100,000 connected vehicles. Security analyses revealed robust protection against eavesdropping, data tampering, and replay attacks, with a detection rate exceeding 98%. Overall, our results underscore the viability and effectiveness of our integrated approach in providing privacy-preserving communication for IoV networks, paving the way for secure and resilient connected transportation systems. As IoV continues to evolve, our approach can contribute to the development of privacy-enhancing technologies that empower users to fully leverage the benefits of connected transportation while safeguarding their privacy rights.

The Internet of Medical Things (IoMT) and Artificial Intelligence (AI) have changed the traditional healthcare scheme to an intelligent system. The data are produced continuously by millions of devices and sensors, exchanging important messages through supporting network devices that monitor and control the smart-world infrastructures. While compared with cloud computing, the data storage or computation are migrated to the network (near end users) by edge computing. Therefore, edge computing is highly required to satisfy intelligent healthcare systems' requirements. However, the confluence of IoMT and AI opens up new potential in the healthcare sector. The main objective of this paper is to create a disease detection model for heart disease utilizing AI approaches. The given model includes many phases, including data gathering, preprocessing for detection of outliers, classification of disease, and weight parameter adjustment. Initially, the Correlation Based Feature Selector (CFS) approach is used in this study to exclude outliers. Then, the research work employs a Chimp Optimization Algorithm (ChOA)-based Recurrent Neural Network (RNN) model for illness diagnosis. ChOA is to fine-tune the 'weights' parameters of the RNN model to categorize medical data better. During the testing, the given ChOA -RNN model achieved extreme accuracies of 96.16 percent in identifying heart disease. As a result, the suggested model may be used as a suitable illness analysis tool for intelligent healthcare systems.
