An Autonomous Vehicle Behavior Decision Method Based on Deep Reinforcement Learning with Hybrid State Space and Driving Risk
Authors: Wang Xu , Qian Bo , Zhuo Junchao , Liu Weiqun
Published: January 2025

Behavioral decision-making is an important part of the high-level intelligent driving system of intelligent vehicles, and efficient and safe behavioral decision-making plays an important role in the deployment of intelligent transportation system, which is a hot topic of current research. This paper proposes a deep reinforcement learning (DRL) method based on mixed-state space and driving risk for autonomous vehicle behavior decision-making, which enables autonomous vehicles to make behavioral decisions with minimal instantaneous risk through deep reinforcement learning training. Firstly, based on the various behaviors that may be taken by autonomous vehicles during high-speed driving, a calculation method for autonomous vehicle driving risk is proposed. Then, deep reinforcement learning methods are used to improve the safety and efficiency of behavioral decision-making from the interaction between the vehicle and the driving environment. Finally, the effectiveness of the proposed method is proved by training verification in different simulation scenarios, and the results show that the proposed method can enable autonomous vehicles to make safe and efficient behavior decisions in complex driving environments. Compared with advanced algorithms, the method proposed in this paper improves the driving distance of autonomous vehicle by 3.3%, the safety by 2.1%, and the calculation time by 43% in the experiment.

Published: January 2025

This study aims to examine context-specific post-migration stress factors and their differential impacts on the mental health of Syrian refugee women resettled in Houston, Texas, and urban communities in Jordan. A cross-sectional survey investigated sociodemographic and health-related conditions, psychological distress and coping (Perceived Stress Scale [PSS]), mental health-related symptomatology (Self-Report Questionnaire [SRQ]), conflict-related psychological distress (Afghan Symptom Checklist [ASC]), and post-migration stress (Refugee Post-Migration Stress Scale [RPMS]). Linear regression models examined factors associated with post-migration stress and mental health outcomes. A total of 127 Syrian refugee women participated in the study. Participants were in their mid-30s (mean age = 34.79 ± 11.2 years), married (66.9%), and reported low levels of education (44.8% below high school), low employment (27.2%), and elevated financial strain (91% below the poverty line). Jordan-based refugees exhibited higher scores on mental distress measures compared to their Houston-based counterparts; specifically more elevated psychological distress (p < 0.001), symptomatology (p < 0.001), and conflict-related distress (p < 0.001). Syrian refugee women in Houston reported higher social strain, while those in Jordan experienced greater financial hardship and barriers to accessing healthcare services. Mental distress among Syrian refugee women is influenced by specific post-migration stressors that vary by resettlement location. Targeted interventions are necessary to improve mental health outcomes in this population.
Factors Influencing Circular Carbon Economy Readiness Among Heavy Industries in China
Authors: Fu Bing , Zailani Suhaiza
Published: January 2025

This study examines the readiness of China’s heavy industries, which account for over 60% of the nation’s energy consumption and carbon emissions, to adopt the Circular Carbon Economy (CCE). CCE, an evolution of the Circular Economy concept, emphasizes carbon reduction, reuse, recycling, and removal. By integrating Institutional Theory, the Resource-Based View (RBV), and the Technology Readiness Level (TRL) framework, this study provides a comprehensive analysis of external and internal factors influencing CCE readiness. Data from 240 respondents were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM), offering a detailed understanding of the readiness landscape. The study combines theoretical insights with empirical validation, enriching the literature and providing actionable guidance for policymakers. Results underscore the importance of regulatory compliance, organizational commitment, and technological readiness in promoting low-carbon practices and advancing CCE readiness, while societal pressures and imitative adaptation showed limited influence. Furthermore, this study represents the first application of the TRL framework to assess CCE readiness in China’s heavy industry. This innovative approach extends the framework’s applicability beyond individual technologies to evaluate industry-wide readiness, offering a replicable methodology for similar studies in other developing countries. The findings bridge gaps in the literature and contribute to the global discourse on sustainable industrial transformation. They provide policymakers and industry leaders with critical insights to design strategies that enhance readiness and support China’s dual carbon goals, fostering a sustainable transition to CCE.

Authors: Di Jianguo , Liu Wenge , Sun Jiaqi , Zhang Dianfeng
Published: January 2025

In order to elucidate the market potential and competition strategies of various photovoltaic (PV) technologies in the context of future architectural trends, taking into account the aesthetic impact and evolving architectural styles, a suite of market assessment methodologies was proposed and applied to systematically evaluate five commercially available PV technologies. Three methodologies were employed or introduced: a comprehensive weighting approach that integrates the TOPSIS entropy weight method with user weight surveys, cumulative prospect theory (CPT), and a market integration method. The survey revealed that price emerged as the paramount factor distinguishing technologies, with a score of 4.8766, closely followed by conversion rates, at 4.8326. Aesthetics was deemed 3% more significant than government subsidies to consumers, scoring 4.4414. During the evaluation, technical indicators were translated into professional financial metrics. The results indicated that crystalline silicon PV technologies hold market advantages in both traditional and transparent applications. Monocrystalline silicon exhibited the highest utility in traditional settings, with a value of −0.0766, whereas polysilicon topped the charts in transparent applications, scoring −0.0676. However, when aesthetics was fully factored in, thin-film technologies began to outperform crystalline silicon, initially in transparent settings and subsequently in traditional ones. When both scenarios were merged, the market share of thin-film PVs increased with a rise in transparent applications, while that of crystalline silicon PVs decreased. Sensitivity and comparative analyses yielded diverse outcomes, validating the robustness of the findings. Further research unveiled that, beyond utility and cost, competition and technological factors also influence market shares, particularly when contemplating future shifts in architectural styles and innovations in product aesthetics. Considering the above, crystalline silicon PV can dominate the PVs in the building market due to their advantages of cost and efficiency, and thin-film PVs can increase their own market share with their aesthetic advantages in the future.
Do Tax Incentives Promote Corporate Green Investment?—Evidence from a Quasi-Natural Experiment Based on China’s Corporate Income Tax Reform
Authors: Xin Daleng , Yi Yanzhen , Shen Lanjun
Published: January 2025

It is essential for achieving green and sustainable economic development by using tax incentives to promote green investment. Using the data from the seventh, eighth, ninth, and tenth Chinese Private Enterprise Surveys (CPESs) conducted by the Private Enterprise Research Group and using China’s corporate income tax reform in 2008 as a quasi-natural experiment, this paper empirically analyses the effect of tax incentives on corporate green investment based on the difference-in-difference models. The research results show that tax incentives can significantly increase corporate green investment. The mechanism test shows that easing financing constraints is an important channel for tax incentives to promote corporate green investment. In addition, the role of tax incentives in promoting green investment varies depending on the type and location of the enterprise. Relatively speaking, tax incentives have a stronger effect in promoting green investment for corporates with low sales revenue, located in the eastern region, heavy pollution, and high innovation capability. By doing placebo tests and changing measurement methods of indicators for robustness tests, the conclusions of this paper are still valid. Therefore, the government should increase tax incentives to better promote corporate green investment.

Authors: Bąk Iwona , Sawińska Agnieszka
Published: January 2025

The sphere of leisure time fulfils important roles in human life, translating into the quality of life of the individual and society. Hence, comprehensive research is being conducted on the ways in which different age groups, including older people, use leisure time. However, few of them take into account factors related to the place of residence, which are important for respondents’ leisure time activities. This study aims to fill the gap in this regard. The aim of the article is to identify socio-demographic variables determining the way adults spend their leisure time, with a particular focus on older people in selected border municipalities in Poland. The study included 1068 individual questionnaire questionnaires completed in 2021 by respondents of border municipalities. One of the non-probability techniques was chosen as the method for selecting elements for the sample, namely, the quota method, which took into account the following characteristics of the population: age, gender, and place of residence. The analyses used selected methods of descriptive statistics and multivariate comparative analysis. The results confirmed that leisure use varied by gender, age, and education. The research also showed that, in the case of older people, leisure time use is influenced by elements relating to their place of residence. Particularly important were the development of green areas in the municipality, safety in the municipality, and the cleanliness of recreational sites.
Integrating Sentiment Analysis and Reinforcement Learning for Equitable Disaster Response: A Novel Approach
Authors: Alqithami Saad
Published: January 2025

Efficient disaster response requires dynamic and adaptive resource allocation strategies that account for evolving public needs, real-time sentiment, and sustainability concerns. In this study, a sentiment-driven framework is proposed, integrating reinforcement learning, natural language processing, and gamification to optimize the distribution of resources such as water, food, medical aid, shelter, and electricity during disaster scenarios. The model leverages real-time social media data to capture public sentiment, combines it with geospatial and temporal information, and then trains a reinforcement learning agent to maximize both community satisfaction and equitable resource allocation. The model achieved equity scores of up to 0.5 and improved satisfaction metrics by 30%, which outperforms static allocation baselines. By incorporating a gamified simulation platform, stakeholders can interactively refine policies and address the inherent uncertainties of disaster events. This approach highlights the transformative potential of using advanced artificial intelligence techniques to enhance adaptability, promote sustainability, and foster collaborative decision-making in humanitarian aid efforts.
A Versatile Electronic Dimer Exhibiting PT and Anti-PT Symmetry
Authors: Li Ruiqi , Gu Jiayang
Published: January 2025

We propose a versatile electronic dimer cooperatively coupled by means of mutual induction, capacitance, and resistance. In a lot of related works, the electronic dimer is inductively coupled, with one resonator characterized by positive resistance (dissipation) and the other by negative resistance (amplification). We go beyond this picture by considering capacitive and resistive coupling, and by exploring cases where both resistances are positive, as well as a case where the resonant frequencies of the individual resonators are different. Based on analytical derivation and numerical calculations, we obtain and observe the properties of parity-time (PT), quasi-PT (QPT) and quasi-anti-PT (QAPT) symmetry by adjusting the constitutive parameters of the system. This study provides a versatile and feasible platform for observing PT/anti-PT (APT) symmetry-based phenomena and provides a foundation for further studies on finding PT/APT symmetry in more sophisticated circuits.
Ball-Flight Viewing Duration and Estimates of Passing Height in Baseball
Authors: Benson Emily , Toole Andrew J. , Fogt Nick
Published: January 2025

Predictions of the vertical location of a pitched ball (termed the passing height) when the ball arrives at an observer may be based on internal models of ball trajectory and situational cues, kinematic cues from the pitcher’s motion, and visual ball-flight cues. The informational content of ball-flight cues for judgments of vertical passing height when the ball’s launch angle is small and when situational and kinematic cues are limited is unknown. The purpose of this study was to determine whether passing heights can be judged adequately from ball-flight cues and whether judgments of passing height improve as viewing time increases under the aforementioned conditions. Twenty subjects stood 40 feet (12.19 m) from a pneumatic pitching machine that propelled tennis balls toward them at three speeds (from 53 mph (85 kph) to 77 mph (124 kph)). The ball’s launch angle was constant. The subject’s vision was blocked at 100 ms or 250 ms after pitch release. Subjects indicated the height at which they expected the ball to arrive. In the absence of explicit situational cues or kinematic cues and in the presence of a small and constant launch angle, the longer viewing time of ball-flight cues improved passing height estimates but did not result in accurate responses for the slower speeds.
Investigation into the Prediction of the Service Life of the Electrical Contacting of a Wheel Hub Drive
Authors: Hempel Markus , Umland Niklas , Busse Matthias
Published: January 2025

This article examines contacting by means of ultrasonic welding between a cast aluminum winding and a copper conductor of a wheel hub drive for a passenger car. The effect of thermal stress on the formation and growth of intermetallic phases (IMC) in the contact is analyzed. By using microscopy, the growth constant under the specific load conditions can be identified with the help of the parabolic time law and offer a possibility for predicting the service life of the corresponding contacts. As a result, it can be stated that the increase in electrical resistance of the present contact at load temperatures of 120 °C, 150 °C, and 180 °C does not reach a critical value. The growth rates of the IMC also show no critical tendencies at the usual operating temperatures (120 °C and 150 °C, e.g., at 150 °C = 4.59 × 10−7 μm2/s). The activation energy calculated using the Arrhenius plot of 155 kJ/mol (1.61 eV) can be classified as high in comparison to similar studies. In addition, it was found that future investigations of the IMC growth of corresponding electrical contacts should rather be carried out with electric current. The 180 °C sample series were carried out in the oven and with electric current; the samples in the oven did not show clear IMC, while the samples exposed to electric current already showed IMC under the microscope.

Authors: Lunitsyna Yu. V. , Shevyakina A. O. , Tokmakova S. I. , Bondarenko O. V.
Published: January 2025

Relevance. Squamous cell carcinoma of the head and neck, including oral and oropharyngeal cancer, ranks as the seventh most common cancer worldwide, contributing to over 660,000 new cases and 325,000 deaths annually. Understanding the interplay of adverse factors, their association with disease development, and the creation of mathematical risk prediction models can play a crucial role in enhancing screening efforts and advancing primary prevention of malignant neoplasms.

Objective. This study aimed to identify significant risk factors for oral mucosa cancer in the Altai Krai population and to develop a mathematical model for disease risk assessment.

Material and methods. The study included 184 patients diagnosed with oral mucosa cancer, along with a control group of 416 healthy volunteers with no history or current diagnosis of oncological diseases. A total of 39 potential risk factors were analyzed across all participants. Statistical analyses were conducted to identify region-specific risk factors for Altai Krai. Binary logistic regression and ROC analysis were used to construct the risk prediction model.

Results. Comparative analysis between the patient group and the control group revealed differences in 19 of the 39 evaluated factors. However, the final risk prediction model identified five key factors significantly influencing disease development. Advanced age, smoking status, the number of cigarettes smoked, and alcohol consumption were found to substantially increase the risk of oral mucosa cancer, while engagement in intellectual work-related activities was associated with a reduced risk. The resulting formula demonstrated high predictive accuracy, with an Area Under the ROC Curve (AUC) of 0.91, a standard error of 0.024, and a 95% confidence interval of 0.856–0.955 (z-statistic: 17.50; significance level: P (area = 0.5) < 0.001). Both the sensitivity and specificity of the model were high.

Conclusion. The developed risk assessment model shows great promise for helping screen and diagnose oral cancer in the Altai Krai population. This tool could give dentists and healthcare providers a simple, practical way to identify individuals at risk early by using well-established risk factors.

Authors: Yatskevich E. E. , Iakusheva T. M. , Sopibekova A. E.
Published: January 2025

Relevance. The quality of life in children aged 13–17 years with amelogenesis imperfecta is a significant medical and social concern in modern dentistry. This issue is particularly important due to several key factors. Firstly, amelogenesis imperfecta is a rare hereditary condition that severely affects enamel formation and development, resulting in considerable functional and aesthetic impairments. Secondly, adolescence, particularly between the ages of 13 and 17, is a critical period for self-esteem development, intensified interpersonal interactions, and an increased emphasis on appearance in social adaptation. Thirdly, while modern dentistry provides various treatment options for amelogenesis imperfecta, their impact on the quality of life of adolescent patients has not been sufficiently studied.

Materials and methods. The study was conducted through the synthesis of clinical case data reported in publications and the practical experience of pediatric dentists at the V. F. Voyno-Yasenetsky Scientific and Practical Center for Specialized Medical Care for Children under the Moscow City Health Department. A total of 120 children were examined.

Results. Children with amelogenesis imperfecta often encounter significant social and psychological challenges, including difficulties in peer communication and the risk of social isolation. Managing such patients requires a comprehensive approach that extends beyond oral health care to include psychological support. The primary objectives of therapy are to preserve the teeth, restore their function, and improve aesthetics. Emphasis should be placed on maintaining oral hygiene through the use of specialized products and techniques. It is essential to consider each child's individual characteristics and address potential psychological barriers to treatment. Effective rehabilitation can greatly enhance the quality of life for these young patients and support their social integration.

Conclusion. The conducted study has revealed a significant impact of this condition on the physical, psychological, and social well-being of patients. The findings highlight the need for a comprehensive treatment approach that incorporates not only oral rehabilitation but also psychological support. Such an integrated approach can enhance the effectiveness of therapy and improve the quality of life of adolescents with amelogenesis imperfecta.

Published: January 2025

Introduction: Primary healthcare facilities are the first point of contact for the utilization of healthcare services. Adopting appropriate infection prevention and control (IPC) measures helps to control the emergence and spread of infection in the community. No study related to the knowledge, attitude, and practice of healthcare workers (HCWs) on IPC was done at the primary health facility level till the date of this study.
Aim: To assess the knowledge, attitudes, and infection control practices among Nepalese HCWs working in primary health facilities.
Methods: This was a descriptive cross-sectional study conducted among 156 health workers from municipalities of the Kathmandu district. Multistage simple random sampling was used in which five municipalities were selected randomly and health workers were selected proportionately afterward.
Results: Out of the total participants, more than half of them had not obtained infection control training. Only 15.4 3.2, and 10.3% of the respondents achieved maximum scores for knowledge, attitude, and practice items, respectively. Although staff had good knowledge and a positive attitude towards most aspects of infection control, nearly two-thirds (62.8%) of the participants had not heard about methicillin-resistant Staphylococcus aureus.
Conclusion: There was an irregular supply of basic supplies such as masks, gloves, aprons, supply of water, hand-washing basins, soap, and hand sanitizer. Therefore, every local level should equip all health facilities of its catchment area with the basic supplies as listed in the Minimum Service Standard guideline for the correct application of IPC.

Published: January 2025

The establishment of robust infection control practices is crucial in any new healthcare facility to ensure patient safety and prevent healthcare-associated infections (HAIs). All India Institute of Medical Sciences (AIIMS) Rajkot, a newly inaugurated medical institution in Western India, faced the significant challenge of implementing these practices from the ground up, beginning with its Outpatient Department services initiation on 31 December 2021.
The AIIMS Rajkot initiated its infection control program by forming a Hospital Infection Control Committee and appointing dedicated Infection Control Officers and Infection Control Nurses. This initiative was supported by comprehensive training programs, the implementation of advanced infection control measures such as bundle care, HAI surveillance, and the development of outbreak investigation teams. Furthermore, the hospital focused on the continuous improvement of these practices through routine audits and the use of a digital Infection Control Risk Assessment form.
The institution successfully integrated a structured infection control framework that includes rigorous training sessions, the implementation of a Hospital Infection Control Manual, and the establishment of a robust needle stick injury management team. These measures have led to improved compliance with infection prevention protocols, as evidenced by hand hygiene audits and reduced incidence of HAIs.
The journey of establishing infection control practices at AIIMS Rajkot highlights the importance of a structured approach in new healthcare settings. The successful integration of these practices not only enhances patient and staff safety but also sets a standard for future healthcare facilities. The AIIMS Rajkot’s proactive measures and continuous improvement efforts serve as a model for effectively addressing the challenges of infection control in a dynamic healthcare environment.

O hipotireoidismo na gestação é uma condição que pode causar diversas complicações maternas e fetais, como pré-eclâmpsia, parto prematuro e comprometimento do desenvolvimento neurocognitivo infantil. Os hormônios tireoidianos desempenham um papel essencial na saúde materna e no desenvolvimento do sistema nervoso fetal. Este estudo visa revisar as principais repercussões do hipotireoidismo gestacional, destacando a importância do diagnóstico precoce e do manejo adequado. Foi realizada uma revisão da literatura nas bases de dados PubMed/MEDLINE e Scielo. Utilizaram-se os descritores "Gestação", "Hipotireoidismo" e "Complicações", combinados pelo operador booleano AND, para identificar estudos relevantes publicados entre 1988 e 2024. Foram selecionados 11 artigos originais que atendiam aos critérios de inclusão, considerando a precisão, relevância e validade das informações apresentadas. Os estudos analisados evidenciaram que o hipotireoidismo clínico e subclínico durante a gravidez está associado a complicações como aborto espontâneo, hipertensão gestacional, descolamento prematuro de placenta, parto prematuro e baixo peso ao nascer. Além disso, a deficiência de hormônios tireoidianos pode prejudicar a mielinização e a formação cerebral fetal, aumentando o risco de déficits cognitivos e psicomotores na criança. Embora o rastreamento universal do hipotireoidismo gestacional ainda seja debatido, há consenso sobre a necessidade de avaliar mulheres em risco, como aquelas com histórico de doença tireoidiana. A reposição de levotiroxina mostrou-se eficaz na prevenção de complicações, especialmente quando iniciada precocemente.

Маргиналы от музыки: образ джазового музыканта в позднесоветском кинематографе
Authors: Журкова Д.А.
Published: January 2025

В статье рассматриваются четыре фильма позднесоветского кинематографа: «Шляпа» (1981), «Мы из джаза» (1983), «Когда святые маршируют» (1990), «Такси-блюз» (1990), в центре сюжетов которых оказываются герои, увлеченные джазом. Через эволюцию образа джазового музыканта в фильмах прослеживаются закономерности в рефлексии поздне­советского кинематографа о судьбе маргинализиро­ванной личности, особенно актуальной в свете стремительно меняющегося социального ландшафта эпохи. Общие лейтмотивы выбранных фильмов анализируются по двум направлениям: 1) психологические лейтмотивы в образе героя-джазмена и 2) особенности саундтрека. В психологической прорисов­ке джазовых музыкантов обозначаются два пути: создание группового и индивидуального портретов. В групповом портрете превалируют авантюрность натуры, страсть к новому и не поощряемому сверху искусству из-за рубежа. В индивидуализированных портретах преобладает личностная драма, сильнейший разрыв героя и с обществом, и с самим собой, обусловленный невозможностью полноценной профессиональной самореализации. Несмотря на то что герои-джазмены недолюбливают популярную музыку, авторы фильмов о джазовых музыкантах обраща­ются к ней, стремясь сделать саундтрек, рассчитанный на широкую публику. В «Шляпе» звучат рок и эстрада, в «Мы из джаза» присутствует стилизация под диксиленд, в «Когда святые маршируют» — знаменитые джазовые стандарты.

The article examines four films of late Soviet cinematography: “The Hat” (1981), “We Are from Jazz” (1983), “When the Saints Go Marching In” (1990), and “Taxi Blues” (1990). At the centre of the plots of all these films are characters with a passion for jazz. The study aims to trace, through the evolution of the image of the jazz musician, important patterns in the reflection of late Soviet cinema on the fate of the marginalised individual, especially relevant in light of the rapidly changing social landscape of the era. The general leitmotifs of the selected films are analyzed along two thematic directions: 1) psychological leitmotifs in the image of the hero-jazzman and 2) features of the soundtrack. Two ways stand out in the psychological portrayal of jazz musicians: creating group and individual portraits. In the group portrait, the image of the jazzman prevails adventurous nature, and passion for new and is not encouraged by the art from abroad. In more individualized portraits of jazz musicians, the personal drama, the hero’s strongest rupture with society and himself, caused by the impossibility of full professional self-realization, takes the upper hand. Although true film jazzmen dislike popular music, authors of films about jazz musicians strive to make a soundtrack designed for the general public. “The Hat” draws on rock and pop, “We Are from Jazz” stylizes Dixieland, and “When the Saints Go Marching In” uses famous jazz standards.

Чилектинский полихронный гранитоидный плутон расположен в Восточно-Магнитогорской подзоне Южного Урала. В плане он имеет форму большой линзы размером 4 × 14 км, вытянутой меридионально. Плутон сложен магматитами двух различающихся по возрасту комплексов: среднепозднедевонского краснинского (3-я фаза) и раннекаменноугольного куйбасовского (1-я и 2-я фазы). На девяти участках, характеризующих различные фазы комплексов массива, проведены исследования анизотропии магнитной восприимчивости и изучен состав магнитных минералов. По магнитным характеристикам и составу магнитных минералов пород Чилектинский плутон схож с подобными гранитоидными плутонами. Не обнаружено принципиальных различий в петромагнитных характеристиках однотипных пород различных комплексов и фаз плутона. По данным магнитной анизотропии на разных участках Чилектинского плутона реконструированы направления растекания магмы и установлена морфология отдельных тел (штоки и дайки).

The Chilektinsky polychronous granitoid pluton is located in the Eastern Magnitogorsk subzone of the Southern Urals. It has an elongated shape 4 × 14 km in size, stretched meridionally. The pluton is composed of magmatites of two complexes: the Middle-Late Devonian Krasninsky (phase 3) and Early Carboniferous Kuibasovsky (phases 1 and 2). The anisotropy of magnetic susceptibility and composition of magnetic minerals were investigated at 9 sites located in different phases of the complexes. The magnetic characteristics and composition of magnetic minerals of rocks of the Chilekta pluton are generally typical to those of similar granitoid massifs. No principal differences in rock magnetic characteristics between similar rock types from different complexes and phases of the pluton were found. On the base of magnetic anisotropy data, magma flow directions were reconstructed in different parts of the Chilekta pluton, and also the morphology of separate magmatic bodies (stocks and dikes) was established.

Многие нефтегазовые месторождения Пермского края характеризуются сложными геологическими условиями и требуют применения современных методов геофизических исследований скважин (ГИС) для обнаружения пропущенных залежей и оценки коллекторских свойств. Традиционные методы ГИС имеют ограничения при оценке таких сложных формаций, однако использование современных расширенных технологий каротажа доказало свою эффективность. В данной работе анализируется стандартный комплекс ГИС, применяемый на месторождениях Пермского края, и оценивается его применимость к сложным геологическим условиям.

Many oil and gas fields in the Perm region are in the late stages of development, with annual reserves dwindling. These fields, characterized by complex geology, thin stratification, and high-water saturation, require advanced geophysical logging (GIS) methods to detect missed hydrocarbon deposits and assess reservoir properties. While traditional GIS methods have limitations in evaluating such complex formations, the use of modern, expanded GIS technologies has proven beneficial. This paper analyzes the standard GIS complex used in Perm region and assesses its applicability to the Perm region’s challenging geological conditions.
Problemas epistémicos ligados a los pilares y dimensiones del desarrollo sostenible

El desarrollo sostenible ha adquirido una enorme relevancia para responder a la crisis ambiental y aunque no surgió de la academia, ha sido adoptada por ésta. Por eso, en este texto se profundiza desde la filosofía y la semiótica en los problemas epistémicos ligados al desarrollo sostenible, la sostenibilidad y la sustentabilidad, que son sintagmas problema que se basan en metáforas. A partir de un análisis bibliográfico cualitativo, de búsqueda de los supuestos implícitos y explícitos del desarrollo sostenible y crítica de sus argumentos, se realiza como objetivo, un análisis teórico-conceptual del modelo de los pilares de la sostenibilidad y de sus dimensiones desde una perspectiva crítica. También como objetivo, se profundiza en la lógica empresarial para comprobar si los tres pilares o tres dimensiones se pueden compatibilizar, y se devela la lógica imperante de construir propuestas de operacionalización del desarrollo sostenible (competencias para la sostenibilidad, indicadores de sostenibilidad y evaluaciones de sostenibilidad) sobre vacíos conceptuales. Con esto, el artículo establece que hay una profunda desconexión entre los niveles conceptual y operativo de la sostenibilidad. En conclusión, se muestra que la sostenibilidad no es un concepto operativo, sino que, en el mejor de los casos, es una hipótesis a demostrar por las generaciones futuras, o bien, de parte de las generaciones actuales respecto de repercusiones de las acciones de generaciones pasadas. Por esta razón, para atender la crisis ambiental, se requiere apelar a alternativas al discurso institucionalizado de la sostenibilidad, como la sustentabilidad, el ecodesarrollo y las perspectivas del Sur Global que incluyen saberes rurales e indígenas.

La Educación a Distancia (EaD) ha demostrado ser una herramienta valiosa para promover la inclusión educativa en comunidades marginadas y rurales, facilitando el acceso a la educación superior y contribuyendo al desarrollo social y humano en estos contextos. El objetivo de este trabajo consistió en analizar el impacto social y económico de los egresados de la modalidad a distancia en comunidades marginales y rurales para identificar áreas de oportunidades. La investigación se desarrolló en el Instituto Tecnológico de San Luis Potosí (ITSLP) perteneciente al Tecnológico Nacional de México (TecNM), con un enfoque cuantitativo y alcance descriptivo. La población de estudio fueron 179 egresados, pertenecientes a los municipios de: El Naranjo, Ahualulco, Moctezuma y Xilitla del estado de San Luis Potosí, de las carreras de Ingeniería Industrial e Ingeniería en Sistemas Computacionales; como instrumento de recolección de información, se aplicó un cuestionario desarrollado en Microsoft Forms compartido por correo electrónico. De las respuestas obtenidas, los resultados arrojaron que el 85% se desempeñan en el campo de su profesión y el 93% mejoraron su situación laboral. Sin embargo, solo el 10% se ha titulado; el problema localizado por lo que no se titulan, es la acreditación del idioma inglés. Respecto al nivel de identidad y pertenencia con la institución, el 100% la recomendaría a amigos, familiares o conocidos. Con base en el análisis de los resultados obtenidos, se puede afirmar que la EaD es una modalidad pertinente para que los jóvenes de comunidades marginadas o rurales continúen su formación profesional.

Published: January 2025

El presente trabajo analiza el impacto en jóvenes adolescentes de Objetos Virtuales de Aprendizaje (OVA), elaborados en el programa de aprendizajes musicales rítmicos Per-Q, como recursos para el desarrollo de la competencia intercultural. Per-Q: Programa de educación musical para ambientes virtuales de aprendizaje, fue un proyecto realizado en los estudios del posgrado de la Maestría en Gestión del Aprendizaje en Ambientes Virtuales del Sistema de Universidad Virtual de la Universidad de Guadalajara, presentado en su primera implementación como un curso en línea de aprendizajes rítmicos. Per-Q promueve la interculturalidad dentro de sus competencias principales, en donde la música se presenta como un elemento que fomenta la diversidad y el reconocimiento de la identidad cultural. Dentro del proyecto se elaboraron recursos digitales de creación original, que presentan información sobre el ritmo y los instrumentos de percusión en las culturas prehispánicas de México. Por medio de una investigación descriptiva mixta, fue posible conocer la percepción y las opiniones de adolescentes en edades entre los 12 y 18 años sobre dos de los recursos propios del programa. Los recursos, que por sus características se consideran como OVA, buscan acercar a las nuevas generaciones a sus raíces y tradiciones culturales por medio de la música e impulsar la competencia intercultural entre los jóvenes mexicanos.
Efficient use of non-steroidal anti-inflammatory drugs for treatment of joint pain in the practice of physicians and pharmacists

Background. Due to the prevalence of dystrophic degenerative diseases, the annual increase in the number of visits from young and middle-aged patients leading an active lifestyle, and the growing frequency of traumatic injuries of various origins, the problem of joint pain is particularly relevant.

Aim. To investigate the main factors influencing the effective and safe use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) in the treatment of joint pain syndrome.

Materials & Methods. Using the developed questionnaire, patients with articular pain syndrome were interviewed about the safety and rational use of NSAIDs.

Results & Conclusions. It was found that most often, people of working age with moderate intensity of pain syndrome sought medical care for joint pain. In one third of respondents, pain was accompanied by impaired motor activity in the joint. The largest proportion of respondents used oral systemic NSAIDs to reduce pain (46.7%), mainly non-selective сyclooxygenase inhi­bitors. A small proportion of patients (13.3%) who used NSAIDs topically preferred diclofenac, ibuprofen, and ketoprofen in the form of ointments and gels. 16.7% of respondents increased the dose of the drug on their own to achieve the desired therapeutic effect. 26.7% of patients simultaneously used several drugs from the NSAID group. However, the majority of the surveyed patients (63.3%) were not informed about the possibility of side effects associated with these drugs. A wide range of modern NSAIDs, a variety of dosage forms, high frequency and duration of use, and the potential risk of side effects require individual prescribing of drugs in this group. Prescribing timely and adequate treatment with a fast, effective and safe pain reliever remains an urgent issue in the daily practice of physicians and pharmacists.

¿La educación preescolar inclina la balanza a favor de las madres en el mercado laboral?
Authors:   , Zulli María Agostina
Published: January 2025

Este trabajo analiza el impacto de la inscripción en preescolar en los resultados laborales de las madres en Brasil, enfocándose específicamente en el efecto de la asistencia al preescolar del hijo menor y cómo este efecto varía según la presencia de otros miembros de la familia en el hogar. Utilizando un diseño de regresión discontinuia difusa que aprovecha los cambios en las regulaciones de edad de entrada al preescolar, encuentro que inscribir al hijo menor en preescolar incrementa en un 40% la probabilidad de participación de las madres en la fuerza laboral y en un 55% su probabilidad de empleo, además de aumentar los ingresos familiares en un 70%. Estos efectos positivos no se observan en las madres que inscriben a niños que no son los menores en el hogar. Cabe destacar que los efectos en el empleo son más pronunciados para las madres que no tienen otras mujeres adultas en el hogar, lo que resalta el papel del cuidado infantil informal en la reducción de las responsabilidades de cuidado de las madres. Los resultados sugieren un efecto positivo en las decisiones laborales de estas otras mujeres, aunque los efectos no son estadísticamente significativos, posiblemente debido al tamaño reducido de la muestra. Adicionalmente, los resultados indican que las decisiones laborales de los padres no se ven afectadas por esta política.

Published: January 2025

This qualitative study sought to examine the perceptions of parents and caregivers of young highly to profoundly gifted learners regarding their child’s social and emotional characteristics and related needs. A phenomenological design was used to collect data from a purposive sample of 12 parents of highly to profoundly gifted children aged 6 – 8 through semi-structured interviews. Data were analyzed using thematic analysis and generated four overarching themes including (a) social-emotional complexity and intensity; (b) nurturing needs during early elementary school; (c) seeking community and understanding; and (d) misunderstanding and misconceptions of HG/PG children. Findings from this study inform educators, counselors, therapists, and related service providers of the lived experiences of families of highly to profoundly gifted children and their needs.
