Published: December 2024

The ionosphere of the Earth often becomes turbulent and develops electron density irregularities that can cause rapid and random changes in the amplitude and phase of radio signals, which is known as ionospheric scintillation. In this study, the statistical behavior of global navigation satellite system (GNSS) ionospheric amplitude scintillation of varying intensities over the Chinese low-latitude station in Sanya (18.34°N, 109.62°E; magnetic latitude: 7.61°N) has been investigated with respect to its dependence on solar activity, seasons, local time (LT), and geomagnetic activity during the period from July 2004 to December 2021. A detailed study on the solar activity dependence of scintillation occurrence shows that the occurrence rates of strong and moderate scintillations significantly increase with enhanced solar activity, but weak amplitude scintillations do not entirely conform to this characteristic. In terms of seasonal dependence, the scintillations in Sanya from 2004 to 2021 mainly occurred during equinoxes and exhibit a distinct equinoctial asymmetry. This asymmetry is characterized by a higher occurrence rate in autumn than in spring during the years 2007, 2011, and from 2017 to 2021, while in other years, the pattern is reversed, with a higher occurrence rate in spring than in autumn. Regarding LT dependence, scintillations are predominantly observed during 19:30–23:30 LT, with a notable persistence beyond midnight during years of high solar activity. Furthermore, geomagnetic disturbances have been observed to promote weak scintillations at 20:00 LT during the autumn and winter of 2014, and from 20:00 LT to 01:00 LT the next day in the latter half of 2013. In contrast, during the spring and autumn of most other years with high solar activity, these disturbances have been found to inhibit weak scintillations from 20:00 LT to midnight. The promoting/inhibiting effect of geomagnetic disturbances on ionospheric scintillation is not solely influenced by electric field disturbances but is to some extent jointly controlled by a variety of factors including solar activity, season, and LT.

Published: December 2024

Current technologies could potentially solve many of the urban problems in today’s cities. Many cities already possess cameras, drones, thermometers, pollution air gauges, and other sensors. However, most of these have been designated for use in individual domains within City Hall, creating a maze of individual data domains that cannot connect to each other. This jumble of domains and stakeholders prevents collaboration and transparency. Cities need an integrated system in which data and dashboards can be shared by city administrators to better deal with urban problems that involve several sectors and to improve oversight. This paper presents a model of an integrative system to manage classes of problems within one administrative municipal domain. Our model contains the cyber-physical system’s elements: the physical object, the sensors and electronic devices attached to it, a database of collected problems, code running on the devices or remotely, and the human. We tested the model by using it on the recurring problem of potholes in city streets. An AI model for identifying potholes was integrated into applications available to citizens and operators so that they can feed the municipal system with images and the locations of potholes using their cell phone camera. Preliminary results indicate that these sensors can detect potholes with an accuracy of 91% and 99%, depending on the detection equipment used. In addition, the dashboards provide the manager and the citizen with a transparent view of the problems’ progress and support for their correct address.
A Lightweight ECC-Based Authentication and Key Agreement Protocol for IoT with Dynamic Authentication Credentials
Authors: Li Momo , Hu Shunfang
Published: December 2024

Due to the openness of communication channels and the sensitivity of the data being collected and transmitted, securing data access and communication in IoT systems requires robust ECC-based authentication and key agreement (AKA) protocols. However, designing an AKA protocol for IoT presents significant challenges, as most IoT sensors are deployed in resource-constrained, unattended environments with limited computational power, connectivity, and storage. To achieve anonymous authentication, existing solutions typically rely on shared temporary public keys to mask device IDs or validate sender certificates, which increases the computational overhead. Furthermore, these protocols often fail to address crucial security concerns, such as nonresistance to ephemeral secret leakage (ESL) attacks and a lack of perfect forward security. To mitigate the computational burden, we propose a dynamic authenticated credentials (DACs) synchronization framework for anonymous authentication. Then, we introduce an ECC-based AKA scheme that employs DACs in place of temporary public keys or sender credentials, enabling efficient and secure anonymous authentication. The security of the proposed protocol was rigorously verified under the Real-or-Oracle model and validated using ProVerif. Performance comparisons demonstrate that our scheme offered significant improvements in security, with an over 37% reduction in communication cost and computational overhead.

Influence of Lamb Wave Anisotropy on Detection of Water-to-Ice Phase Transition
Authors: Smirnov Andrey , Anisimkin Vladimir , Ageykin Nikita , Datsuk Elizaveta , Kuznetsova Iren
Published: December 2024

An important technical task is to develop methods for recording the phase transitions of water to ice. At present, many sensors based on various types of acoustic waves are suggested for solving this challenge. This paper focuses on the theoretical and experimental study of the effect of water-to-ice phase transition on the properties of Lamb and quasi shear horizontal (QSH) acoustic waves of a higher order propagating in different directions in piezoelectric plates with strong anisotropy. Y-cut LiNbO3, 128Y-cut LiNbO3, and 36Y-cut LiTaO3 plates with a thickness of 500 μm and 350 μm were used as piezoelectric substrates. It was shown that the amplitude of the waves under study can decrease, increase, or remain relatively stable due to the water-to-ice phase transition, depending on the propagation direction and mode order. The greatest decrease in amplitude (42.1 dB) due to glaciation occurred for Lamb waves with a frequency of 40.53 MHz and propagating in the YX+30° LiNbO3 plate. The smallest change in the amplitude (0.9 dB) due to glaciation was observed for QSH waves at 56.5 MHz propagating in the YX+60° LiNbO3 plate. Additionally, it was also found that, in the YX+30° LiNbO3 plate, the water-to-ice transition results in the complete absorption of all acoustic waves within the specified frequency range (10–60 MHz), with the exception of one. The phase velocities, electromechanical coupling coefficients, elastic polarizations, and attenuation of the waves under study were calculated. The structures “air–piezoelectric plate–air”, “air–piezoelectric plate–liquid”, and “air–piezoelectric plate–ice” were considered. The results obtained can be used to develop methods for detecting ice formation and measuring its parameters.

Authors: Bistroń Marta , Piotrowski Zbigniew
Published: December 2024

Image reconnaissance systems are critical in modern applications, where the ability to accurately detect and identify objects is crucial. However, distortions in real-world operational conditions, such as motion blur, noise, and compression artifacts, often degrade image quality, affecting the performance of detection systems. This study analyzed the impact of super-resolution (SR) technology, in particular, the Real-ESRGAN model, on the performance of a detection model under disturbed conditions. The methodology involved training and evaluating the Faster R-CNN detection model with original and modified data sets. The results showed that SR significantly improved detection precision and mAP in most interference scenarios. These findings underscore SR’s potential to improve imaging systems while identifying key areas for future development and further research.

Published: December 2024

Foods rich in polyphenols have beneficial effects on health. This study aimed to examine the impact of dark chocolate on endurance runners’ arterial function. Forty-six male amateur runners, aged 25–55, participated. The initial assessments included clinical testing, arterial stiffness measurements, and a cardiopulmonary exercise test. The participants then consumed 50 g of dark chocolate (70% cocoa) daily for two weeks, maintaining their usual training routine. After this period, the baseline assessment was repeated. The results showed significant improvements. Pulse wave velocity decreased by 11.82% (p < 0.001), and augmentation index by 19.47% (p < 0.001). Systolic brachial blood pressure reduced by 2.12% (p < 0.05), diastolic by 2.79% (p < 0.05), and mean pressure by 2.41% (p < 0.05). Central arterial pressure also decreased, with systolic by 1.24% (p < 0.05), diastolic by 2.80% (p < 0.05), and mean pressure by 2.43% (p < 0.05). Resting heart rate increased by 4.57% (p < 0.05) and left ventricular ejection time decreased by 4.89% (p < 0.05), particularly in athletes over 40. Exercise time increased by 2.16% (p < 0.05), heart rate (max) by 1.15% (p < 0.05), VO2max by 2.31% (p < 0.05), and anaerobic threshold shifted by 6.91% (p < 0.001) in exercise time and 6.93% (p < 0.001) in VO2max. In conclusion, dark chocolate improves arterial function in endurance runners, enhancing vascular health.
Tracking of Antibiotic Resistance Genes in Sludge from Treatment Plants for Organic Fraction of Municipal Solid Waste
Authors: Franchitti Elena , Mafrica Antonino , Traversi Deborah
Published: December 2024

Bacteria quickly acquire the ability to survive or grow in the presence of an antibacterial agent that should be able to inhibit or kill them, leading to increased mortality caused by infective diseases. The digestate from the anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW) is spread on soil, but the knowledge on the presence and persistence of the antibiotic resistance genes (ARGs) is limited. Thus, this study aims to evaluate the presence of seven ARGs (blaTEM, blaOXA, ermB, qnrB, sulI, sulII, tetA, and tetW) in the OFMSW and their persistence after the AD, using the innovative droplet digital Polymerase Chain Reaction (ddPCR), not yet used on this matrix. A total of 31 samples were collected from the influent and effluent of the AD in two plants located in Northern Italy. ARG concentration ranged between 4 and 9 Log gene copies/kg of sludge. A limited reduction in the concentration of antibiotic resistance targets given by AD was observed in the study (<1 Log). The persistence of ARGs after mesophilic digestion of the OFMSW suggests a risk of horizontal transmission when directly spread on soil. Further evaluations are needed for safe and sustainable reuse of such sludges.
Comprehensive Assessment of Groundwater Hydrochemistry, Driving Forces, Water Quality, and Associated Health Hazards in the Wen River Basin, Northern China
Authors: Tan Menghan , Gao Zongjun , Jiang Bing
Published: December 2024

Groundwater is essential for water resources, serving as a key drinking source in China. It supports daily needs for urban and rural residents, aids development, and maintains ecological balance. This study conducted a sampling survey of groundwater in the Wen River basin (WRB), assessing hydrochemical features, genesis mechanisms, water quality, and health risks. The findings reveal that groundwater in the WRB is weakly alkaline, with an average total dissolved solids (TDS) concentration of 755.24 mg/L. Freshwater constitutes approximately 81.48% of the groundwater, with the following order of concentration for cations: Ca2+ > Na+ > Mg2+ > K+, and for anions: HCO3− > SO42− > NO3− > Cl−. The predominant hydrochemical types are SO4·Cl-Ca·Mg and HCO3-Ca·Mg. The chemical composition of the groundwater is primarily influenced by silicate rock weathering, dissolution processes, cation exchange, and human activities. The average Environmental Water Quality Index (EWQI) value of 74.65 for the WRB signifies that the overall quality of the groundwater is quite good, indicating that the majority of the groundwater is suitable for drinking purposes. Notably, the inferior quality water is predominantly found downstream of the Wen River. Calculations of the sodium adsorption ratio (SAR), residual sodium carbonate (RSC), and percentage of sodium (%Na) indicate that groundwater at most sampling points is suitable for irrigation. Furthermore, the human health risk assessment (HRA) reveals that oral intake presents a greater health risk to individuals than dermal contact. The mean Hazard Index (HI) for children is 3.24, with a staggering 79.89% of non-carcinogenic health risk (NHR) values surpassing the acceptable standards. For adults, the mean HI is 1.39, with 53.44% of NHR values exceeding the standards. These data indicate that children are more susceptible to health risks than adults and that the midstream and downstream of the river exhibit higher health risks compared to the upper reaches. These findings can provide critical data for groundwater quality assessment and risk management in the WRB and offer guidance for future groundwater resource management and pollution control efforts.

Published: December 2024

Incorporating sewage sludge (SS) into soils presents a cost-effective and environmentally friendly option compared to conventional farming practices. However, SS could be perceived as a double-edged sword, as it may contain a broad spectrum of contaminants, such as heavy metals (HMs), microplastics (MPs), Pharmaceuticals in the Environment (PIE), and personal care products (PSPs), raising concerns for soil health, water resources, food safety, and human health. Council Directive 86/278/EEC, which regulates SS application in agriculture, specifies limits for six HMs but has not undergone substantive revisions since its inception in 1986, until the release of the updated working document SWD-2023-{final 158}. This study critically examines the legislative landscape across the European Union (EU) Member States (MSs), identifying heterogeneity in implementation, regulatory gaps, and the absence of thresholds for emerging contaminants. The results reveal significant disparities in the permissible concentrations of HMs across MSs and in comparison to international guidelines established by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). Furthermore, the absence of regulatory measures for MPs, PIE, and other common soil pollutants underscores critical deficiencies in the current framework. These inconsistencies contribute to varying levels of soil health across the EU and highlight the need for a harmonized approach. The findings of this study highlight the imperative for a comprehensive overhaul of the EU legislative framework governing SS application. As evidenced, the establishment of harmonized contaminant thresholds, rigorous monitoring protocols, and regulatory provisions for emergent pollutants is essential for addressing the identified regulatory gaps, enhancing legislative coherence, and promoting sustainable agricultural practices aligned with the EU’s environmental and public health objectives.

Green logistics talent is becoming increasingly scarce in this era of global sustainability. However, there has been a lack of research on how to develop this. This study explores effective approaches to cultivating green logistics talent within Chinese universities. The University of Science and Technology Liaoning (USTL), a university that has made outstanding achievements in green logistics talent cultivation (GLTC), was reported as a case study. The initiation, processes, and effects of GLTC at the USTL were introduced in detail. The nine processes included establishing cultivation objectives, determining the knowledge system, developing the course named Green Logistics Virtual Simulation Experiment, publishing the textbook Green Logistics Theory and Experiment, setting up the global Virtual Office for GLTC, promoting the reform of teaching model, etc. The four effects include 180,000+ people from more than 140 colleges worldwide using the course, a significant improvement in the quality of students’ green logistics knowledge and skills, etc. Finally, six successful experiences of GLTC at the USTL were analyzed, and a successful model was constructed. This study provides a comprehensive model for cultivating green logistics talent within higher education, using USTL as a case study, which provides important references for GLTC not only for Chinese universities but also for global universities.

Published: December 2024

Air pollution is a vital concern for developing countries, and the growing concentration of air pollutants in Kabul—the most polluted city in Afghanistan—has raised concerns about the health of its citizens. This study examines Kabul’s ambient air quality from a socio-economic and environmental perspective, primarily focusing on some crucial parameters, such as the Air Quality Index (AQI), nitrogen dioxide (NO2), particulate matter (PM2.5), and carbon monoxide (CO). Using multiple regression analysis modeling in R and data from satellite imagery, air quality monitoring stations, and Geographic Information Systems (GIS), this study demonstrates a strong relationship between air quality and urban green spaces, population growth, vehicle count, temperature, and electricity availability. Key results indicate that increasing urban green areas improves air quality, but that population growth and heat make air pollution worse. This study suggests that airborne pollutants could be reduced through efficient emissions management, green energy sources, and urban planning. These observations provide policymakers and urban planners with practical recommendations to enhance Kabul’s air quality and general public health.
Modeling and Solving the Multi-Objective Vehicle Routing Problem with Soft and Fuzzy Time Windows
Authors: Chen Ailing , Li Tianao
Published: December 2024

In the distribution field, distribution costs and customer service satisfaction are extremely important issues for enterprises. However, both the Vehicle Routing Problem with Soft Time Windows (VRPSTW) and the Vehicle Routing Problem with Fuzzy Time Windows (VRPFTW) have certain deficiencies in describing real-world scenarios. Therefore, this paper considers both soft time windows and fuzzy time windows, improving upon the traditional VRPSTW and VRPFTW models to establish a more comprehensive and realistic model called the Vehicle Routing Problem with Soft Time Windows and Fuzzy Time Windows (VRPSFTW). Secondly, to solve the relevant problems, this paper proposes a Directed Mutation Genetic Algorithm integrated with Large Neighborhood Search (LDGA), which fully utilizes the advantages of the Genetic Algorithm (GA) in the early stages and appropriately adopts removal and re-insertion operators from the Large Neighborhood Search (LNS). This approach not only makes efficient use of computational resources but also compensates for the weaknesses of crossover and mutation operators in the later stages of the genetic algorithm. Thereby, it improves the overall efficiency and accuracy of the algorithm and achieves better solution results. In addition, in order to solve multi-objective problems, this paper employs a two-stage solution approach and designs two sets of algorithms based on the principles of “cost priority” and “service-level priority”. Simulation experiments demonstrated that the algorithms designed in this study achieved a more competitive solving performance.

Published: December 2024

Objectives of the study: The aim of this study was to assess the impact of the COVID-19 pandemic on the epidemiology and clinical course of chickenpox in children based on 6 years of self-reported observations. MATERIAL AND METHODS: The medical records of 350 patients under 18 years of age hospitalised in the Department of Paediatrics, Infectious Diseases, and Hepatology between 1 January 2018 to 31 December 2023 were analysed retrospectively. RESULTS: During the analysed period, 350 children were hospitalised due to chickenpox, the fewest in the pandemic period, the greatest number in 2023. Complications of chickenpox were diagnosed in 297 children (84.86%). The most commonly diagnosed complications were bacterial dermatitis (168, 48%) and lower respiratory tract infections (13.42%). After the pandemic period, a generalised inflammatory reaction was observed significantly more often (p ≤ 0.01069). Among children hospitalised in 2023, 5.90% of patients with bacterial dermatitis required surgical intervention due to skin abscess or fasciitis. In 2023, 41.46% of cultures from swabs taken from skin lesions grew Streptococcus pyogenes. After the pandemic, children with chickenpox and gastrointestinal symptoms were hospitalised significantly less frequently (p ≤ 0.00001). CONCLUSIONS: In the post-pandemic period, there were more hospitalisations of patients with chickenpox complicated by bacterial skin infection progressing to a generalised inflammatory reaction or septicaemia, related to the increase in invasive group A streptococcal infections observed in Europe. On the other hand, thanks to the widespread adaption of hygiene practices and infection prevention measures, the number of patients with gastrointestinal symptoms significantly decreased.
Emerging Alternatives to Mitigate Agricultural Fresh Water and Climate/Ecosystem Issues: Agricultural Revolutions
Authors: Bushnell Dennis M.
Published: December 2024

Fresh-water food production/agriculture for both plants and animals utilizes some 70% of the planets’ fresh water, produces some 26% of greenhouse gas emissions and has a longish list of other societal-related issues. Given the developing and extant shortages of arable land, fresh water and food, along with climate/ecosystem issues, there is a need to greatly reduce these adverse effects of fresh-water agriculture. There are, especially since the advent of the 4th Agricultural Revolution, a number of major frontier technologies and functionality changes along with prospective alternatives which could, when combined and collectivized in various ways, massively improve the practices, adverse impacts and outlook of food production. These include cellular/factory agriculture; photosynthesis alternatives; a shift to off-grids and roads/back-to-the-future, do-it-yourself living (aka de-urbanization); cultivation of halophytes on wastelands using saline water; insects; frontier energetics; health-related market changes; and vertical farms/hydroponics/aeroponics. Shifting to these and other prospective alternatives would utilize far less arable land and fresh water, produce far less greenhouse gases and reduce food costs and pollution while increasing food production.
Analysis of the Differences Between Two Landslides on One Slope in Yongguang Village Based on Physical Models and Groundwater Identification

Published: December 2024

In 2013, a Ms 6.6 earthquake occurred at the boundary of Min County and Zhang County, triggering numerous landslides. Notably, two landslides with significantly different sliding characteristics emerged less than 100 m apart in Yongguang Village, Min County. The eastern landslide was characterized by instability induced by seismic inertial forces, whereas the western landslide exhibited flow slides triggered by liquefaction in loess. To further analyze the causes of these landslides, this study employed a 1 m depth ground temperature survey to probe the shallow groundwater in the area, aiming to understand the distribution of shallow groundwater. Based on the results from the 1 m depth ground temperature survey, a random forest model was applied to regressively predict the initial groundwater levels. The TRIGRS model was utilized to evaluate the influence of pre-earthquake rainfall conditions on landslide stability, and the pore water pressure outputs from TRIGRS were integrated with the Scoops3D model to analyze landslide stability under seismic effects. The results indicate that the combination of the 1 m depth ground temperature survey with high-density electrical methods and random forest approaches effectively captures the initial groundwater levels across the region. Notably, the heavy rainfall occurring one day prior to the earthquake did not significantly reduce the stability of the landslide in Yongguang Village. Instead, the abundant groundwater in the source area of the western landslide, combined with several months of pre-earthquake rainfall, resulted in elevated groundwater levels that created favorable conditions for its occurrence. While the primary triggering factor for both landslides in Yongguang Village was the earthquake, the distinct topographic and groundwater conditions led to significantly different sliding characteristics under seismic influence at the same slope.
Analysis of the level and dynamics of wages in agriculture
Authors:   Russian State Agrarian University — Moscow Timiryazev Agricultural Academy, Moscow, Russia, Dashieva B. Sh.
Published: December 2024

The article analyzes the dynamics of the ratio of the average monthly accrued
wages of agricultural workers to wages in the economy as a whole over a long
period of time, as a result of which four sub-periods were identified: the first — from
1959 to 1990, the second — from 1991 to 1999, the third — from 2000 to 2005, the
fourth — from 2006 to the present, characterized by different trends. Despite the growth
of nominal and real average monthly accrued wages of employees of organizations by
the type of economic activity «Agriculture, forestry, hunting, fishing and fish farming»,
its level remains one of the lowest among all types of economic activity, which negatively
affects the attractiveness of the agricultural sector for the employment of young
people, university graduates and older workers. In addition, the gap in the average
monthly accrued wages in agriculture with the highest paid type of economic activity
«Financial and insurance activities» reaches threefold differences. Whereas in one of
the most developed countries in Norway, which ranks second in the world in the human
development index, this gap is 1,7 times. It was determined that the variation in wages
by subjects of the Russian Federation is quite low and amounts to 28 %. It was also
revealed that even in the leading regions producing the largest volumes of agricultural
products (Krasnodar Krai and Rostov Oblast) among all regions of the country, the level
of wages in agriculture is low and is at an average level, but at the same time in the
Belgorod Region, which is distinguished by a high level of intensification and efficiency
of production, ranking third in terms of agricultural production, wages are paid 27 %
higher than the average level in the industry as a whole in all subjects of the Russian
Federation, which indicates the possibility of increasing the level of wages in agriculture
to a comparable level in other types of economic activity.

Published: December 2024

O artigo pretende problematizar objetos utilizados para a escrita e que se caracterizam como artefatos escolares tais como a pena, a caneta de pena e o tinteiro. Estes materiais foram essenciais ao ato de escrever cujo lugar de encontro se materializa na própria escrita. A pena, a caneta de pena e o tinteiro foram artefatos utilizados em âmbito escolar e não-escolar e que estiveram mobilizados, principalmente no século XIX no Brasil e também no início do século XX, por uma elite alfabetizada. Suas memórias e prescrições de uso foram deixadas em anúncios de ropaganda em revistas de ensino e em manuais didáticos. Rastrear estes usos através de sua circulação nestes impressos permitirá despertar marcas desse material, aparentemente banal, no presente, mas que serviu no passado para a aprendizagem e desenvolvimento da escrita. Utilizados para a escrita manuscrita, envolviam além da aprendizagem do ato de escrever e copiar, um treino caligráfico e o esforço muscular para seu uso com tinta e suas diferentes ponteiras. A abordagem teórica-metodológica centra-se na pesquisa bibliográfica articulada com imagens propagandeadas em impressos buscando ampliar possibilidades de conhecer um repertório de práticas do passado que ainda assolam nosso presente. Como resultados do estudo pretende-se demonstrar que esses artefatos usados para a escrita na escola e fora dela, circularam nos impressos como propagandas ou como indicativos para a aprendizagem e usos, demonstrando o modo como a escola e seus materiais foram sendo constituídos ao longo dos anos.

Authors: Ceylan İsmail , Dalakçı Muhammed Samed , Taşkaya Cengiz
Published: December 2024

Aim; Psychological problems are common throughout the world. Due to psychological problems such as stress and anxiety, the sympathetic nervous system is activated. Constant worry causes several physical, mental, and social difficulties, which threatens an individual's health. There are many methods used to overcome this troublesome situation, and one of them is massage. Massage has been used for thousands of years in many parts of the world. Massage therapy has a variety of biomechanical, physical, neurological, and psychosocial effects. Considering the positive effects of facial massage, it seems useful to investigate its effects on cognitive functions. However, as far as we have researched, there are few studies on the effects of facial massage in the treatment of cognitive functions. Therefore, our study aimed to examine the effect of facial massage on the anxiety and attention level of university students in the acute period by utilizing the effect of massage on blood flow and autonomic system.
Method; Classical facial massage was applied to 59 randomly selected first- and second-year university students, and the acute effects of the massage were recorded. Burdon Attention Test, Beck Anxiety Test and pulse measurement methods were used for evaluation.
Results; According to the results obtained, a significant decrease in pulse (p=0.001) and anxiety level (p=0.001) was observed immediately after the classical massage.
Conclusion; Classic facial massage is effective on pulse, anxiety. We hope that the result obtained on the effect on cognitive function will guide subsequent studies.
Pueblos indígenas y justicia en América Latina: una reflexión histórico-antropológica sobre el concepto de pluralismo legal
Authors: Cunill Caroline , Llanes Rodrigo
Published: December 2024

El trabajo compara fundamentos teóricos, características y beneficiarios de sistemas de justicia desarrollados en América Latina en dos momentos históricos: la época colonial y el período de reformas constitucionales de los años 1990, cuando se implementaron vías diferenciadas de acceso a la justicia para categorías distintas de personas. Se analizan los argumentos esgrimidos y los intereses en juego en la defensa de un modelo diferenciado de acceso a la justicia; las condiciones en las que se crearon tribunales gestionados por pueblos indígenas; y el reconocimiento de los sistemas normativos autóctonos por la Corona española y los Estados nacionales. Esta reflexión, que entrelaza el acercamiento histórico y antropológico, va de la mano de aquella que atañe a la forma en que el concepto de pluralismo legal se ha erigido como categoría para investigar los sistemas normativos de América Latina en diversos momentos de su historia, así como a las alternativas surgidas desde entonces.
Reseña sobre: Cuerpos bajo vigilancia: las mujeres en las misiones jesuíticas del Chaco, de Beatriz Vitar (2022)
Authors: Outeiral Imposti Lucía

La historiografía tradicionalmente ha desestimado el estudio sobre las prácticas y los roles de las mujeres indígenas en el Gran Chaco colonial replicando los argumentos de las fuentes jesuíticas sin realizar un cuestionamiento lo suficientemente crítico de ellos. En su nuevo libro, Cuerpos bajo vigilancia: las mujeres en las misiones jesuíticas del Chaco, Beatriz Vitar presenta los resultados de las investigaciones que ha realizado durante toda su trayectoria sobre la temática y analiza las fuentes más allá de lo que estas dicen de manera explícita, para así recuperar la realidad indígena femenina que se esconde detrás de las plumas eclesiásticas. El propósito del presente texto es reseñar su trabajo.
Dionysius the Areopagite and the Legacy of Iamblichus
Authors: Riesgo Gustavo
Published: December 2024

Neoplatonism takes a significant turn when Iamblichus integrates a mystical perspective based on the Chaldean Oracles into his doctrine. This compilation of fragments, which can be traced back to Babylonian Zoroastrianism, emerged in Hellenistic civilization and gained prominence as hermetic texts among philosophers from the 2nd century onward. For Iamblichus, the Neoplatonic concern regarding the feasibility of a return to the One is addressed not primarily through abstract theoretical philosophy, but rather through a philosophical wisdom illuminated by theurgic practice. Iamblichus affirms the legitimacy of the rites detailed in these hieratic texts by asserting that they were divinely inspired by God to Julian. Syrianus and Proclus play crucial roles in preserving and transmitting this legacy. By inheriting Iamblichus’ teachings, they not only regarded this theurgical approach as a quasi-refoundational element of Neoplatonism but also introduced their own contributions to its development. Moreover, they served as the intermediaries through whom these doctrines reached the author of the Corpus Dionysiacum. At this point, Dionysius the Areopagite enters the narrative. He revitalizes the concept of theurgy, though –as this work will endeavor to demonstrate– his effort to integrate Neoplatonism with Christianity reflects a return to Iamblichus’ original interpretation of theurgy. Dionysius’ doctrines provide a robust foundation for him to argue that the Christian rites instituted by Jesus –being performed by God himself, in and through his very person– are doubly true. Therefore, these rites assuredly lead to theosis, the sole means of achieving the union of the soul with the Christian God.
Entre Adán, la muerte y la causa: la exégesis patrística de Romanos 5:12 en la carta 152 de Focio
Authors: Rivera Díaz Pedro Emilio
Published: December 2024

El corpus epistolar de Focio, patriarca de Constantinopla en dos ocasiones (858-867 y 877-886), representa un documento significativo para la historia literaria no solo por su cantidad sino también por sus destinatarios y remitentes, que incluyen personajes importantes de su momento, así como amigos y familiares. A su vez, los contenidos son variados pues oscilan entre temas de corte personal, político, teológico y religioso. Entre las cartas se encuentra la 152, dirigida a su hermano Tarasio, en la que desarrolla la cuestión del sentido que diversos Padres de la Iglesia dieron a la frase “ἐφ᾽ ᾧ” en Romanos 5:12, tanto aquellos que considera incompletos (pues sobreentienden “Adán” o “muerte”), como el más idóneo (“porque”). Sin embargo, debido a que Focio no especifica abiertamente ninguna de sus fuentes, desde la publicación de esta carta (1651) se han hecho intentos por ubicarlas y comentarlas. El objetivo de este trabajo consiste en analizar bajo una nueva perspectiva aquellas que han sido ubicadas, así como presentar otra que no ha sido considerada hasta ahora.
Dionisio Areopagita y el legado de Jámblico
Authors: Riesgo Gustavo Ángel
Published: December 2024

El neoplatonismo da un giro significativo cuando Jámblico integra a su doctrina una perspectiva mística basada en los Oráculos Caldeos. Esta recopilación de fragmentos, que se remonta al zoroastrismo babilónico, surgió en la civilización helenística y ganó relevancia como textos herméticos entre los filósofos a partir del siglo II. Para Jámblico, la preocupación neoplatónica sobre la posibilidad de un retorno al Uno se aborda no tanto a través de una filosofía puramente abstracta, sino mediante una sabiduría filosófica iluminada por la práctica teúrgica. Jámblico afirma la legitimidad de los ritos detallados en estos textos hieráticos, sosteniendo que fueron inspirados por Dios mismo a Juliano. Siriano y Proclo desempeñan un papel crucial en la preservación y transmisión de este legado. Al heredar las enseñanzas de Jámblico, no solo consideraron este enfoque teúrgico como un elemento cuasi refundacional del neoplatonismo, sino que también introdujeron sus propias contribuciones a su desarrollo. Además, actuaron como los intermediarios a través de los cuales estas doctrinas llegaron al autor del Corpus Dionysiacum. En este punto, Dionisio Areopagita entra en escena. Él revitaliza el concepto de teúrgia, aunque –como este trabajo tratará de demostrar– su intento de integrar el neoplatonismo con el cristianismo refleja un retorno a la interpretación original de la teúrgia por parte de Jámblico. Las doctrinas de Dionisio proporcionan una base sólida para que él sostenga que los ritos cristianos instituidos por Jesús –siendo realizados por Dios mismo, en y a través de su propia persona– son doblemente verdaderos. Por lo tanto, estos ritos conducen ciertamente a la theosis, el único medio para lograr la unión del alma con el Dios cristiano.
Câncer de mama em gestantes e a segurança dos tratamentos disponíveis: uma revisão de literatura
Authors: Eckert Luiza Jandira , Corrêa Igor Rodrigues , Pereira Jessica Santos
Published: December 2024

O presente estudo tem o objetivo de realizar uma revisão de literatura para abordar a problemática do diagnóstico da neoplasia de mama na população de gestantes e mostrar as opções terapêuticas, como se realiza o estadiamento, a histologia mais prevalente, a organogênese fetal quando expostos aos diferentes tipos de tratamento e a segurança materna de acordo com a modalidade da terapia escolhida. O câncer de mama gestacional varia de cerca de 0,2% a 3,8%, entre todos os tipos de câncer de mama. Aproximadamente 15% dos diagnósticos são realizados antes dos 35 anos, sendo que 50% deles ocorrem durante o período gestacional e 50% durante a amamentação. O diagnóstico pode ocorrer de forma mais tardia devido às modificações gravídicas, apresentando um pior prognóstico. Mesmo com a grande quantidade de tratamentos, poucos se mostram seguros durante a gestação. Metodologia: consistiu em uma revisão de literatura, por meio da leitura de artigos junto às bases de dados: Google acadêmico, PubMed e Scielo, tendo como palavras-chave: Câncer de mama; Gestação; Oncologia Perinatal. Foram selecionados os artigos dos últimos 5 anos em línguas inglesa e portuguesa. Discussão: Pacientes portadoras de neoplasia de mama durante o período gestacional têm um maior risco de apresentar diagnóstico tardio devido às modificações gravídicas, o que leva a um pior prognóstico. Os tratamentos com maior segurança incluem a mastectomia e a quimioterapia, que devem ser realizados após o primeiro trimestre. A radioterapia mostrou-se contra indicada em todos os períodos gestacionais, sendo reservada para o pós-parto devido às modificações na organogênese fetal. Conclusão: o estudo apresenta a possibilidade de aprofundar o conhecimento sobre a segurança dos tratamentos realizados em gestantes portadoras de neoplasias mamárias, buscando avançar na qualidade do manejo e na segurança da terapia tanto para o feto quanto para as pacientes.

A gravidez na adolescência é uma questão de saúde pública com impactos psicossociais significativos. Este artigo analisa os desafios enfrentados por jovens mães, incluindo riscos à saúde materna e fetal, interrupção da educação e limitações de emprego. Fatores como a falta de informações sobre contracepção e condições socioeconômicas desfavoráveis contribuem para essa situação. A pesquisa qualitativa e descritiva foi realizada durante um estágio em um hospital de média complexidade, utilizando dados de históricos médicos, entrevistas e revisão de literatura. O relato de uma paciente de 14 anos com descolamento prematuro de placenta ilustra os riscos associados à gravidez na adolescência, como choque hipovolêmico e morte fetal intrauterina. O artigo conclui que a gravidez na adolescência é multifatorial, impactando a saúde física e mental das jovens, perpetuando ciclos de pobreza e limitando oportunidades educacionais. Uma abordagem multiprofissional é essencial para promover melhores desfechos para mães e bebês.

Published: December 2024

Introdução: A Compulsão alimentar (CA) se caracteriza pela ingestão de grandes quantidades de comida em um curto período, acompanhada por uma sensação de perda de controle. Este comportamento pode levar a consequências adversas, como ganho de peso, problemas metabólicos e transtornos alimentares, além de impactos negativos na autoestima e no bem-estar emocional. A modulação da microbiota intestinal em pessoas com CA tem ganhado atenção como uma abordagem complementar no tratamento de distúrbios alimentares. Objetivo: Analisar as evidências acerca da modulação da microbiota intestinal identificando os gêneros e bactérias envolvidos na compulsão alimentar, visando o controle dos efeitos do transtorno. Metodologia: É uma revisão integrativa da literatura nas bases de dados científicas Pubmed, Scielo, Google acadêmico e Lilac, nos idiomas inglês espanhol e português. Resultados e Discussão: Foram incluídos 7 artigos que no total descreveram 19 microrganismos envolvidos nos efeitos da CA, que podem agir na regulação da alimentação e emoção do hospedeiro de forma positiva ou negativa, modulando a composição do microbiota, ou com relação a certos tipos de hormônios envolvidos na CA. Conclusão: O principal probiótico pesquisado é do gênero Bifidobacterium, que é o mais abundante na microbiota intestinal do ser humano. A partir da avaliação dos achados observa-se que os microrganismos podem diminuir bactérias patogênicas e aumentar de bactérias benéficas para o organismo, além de auxiliar como um biomarcador metabólico.
