Authors: Danilova L. N.
Published: November 2024

Importance. The power of the Internet enables universal literacy, access to education for girls and children with disabilities, etc. The study aims to analyse the implementation of Internet and digital technologies into Ghana’s schools, which reveals the problems of this area, national specifics of integration, and ambitious projects of the government.

Materials and Methods. Based on comparative, sociological, statistical, and factor analysis, the educational documentation of Ghana, some international organisations, Ghanaian research, sociological surveys, reports from official departments, and feedback from students, teachers, and the media on the issue of digital technologies in schools have been studied.

Results and Discussion. National statistics on access to the Internet and the use of digital technologies by citizens in everyday life and on access and digital skills of Ghanaian teachers are analysed. The factors determining implementation of the Internet and technologies in Ghana’s society have been identified. The problems hindering digital integration in the school education system of Ghana have been identified. The legal framework for the digitalisation of Ghanaian education has been defined. The most significant projects of general education digitalisation are characterised and analysed.

Conclusion. Ghana has developed their information and communications technology policy that includes education digitalisation, which directions are appropriate infrastructure, educational environment, professional development of teachers, and development of schoolchildren's digital skills. They are supported legislatively, financially, and methodically; the authorities and public organisations implement different significant projects related to digital and technology Internet access. However, most of them are aimed only at certain small student groups, keeping many schoolchildren outside the technological modernization. Organisational difficulties that create such a contradiction include material and financial deficits of education and subjective rejection.
From ideological uniformity to thematic diversity. Some reflections on the modern historiography of the New Economic Policy
Authors: Nikulin V. V.
Published: November 2024

Importance. Analysis of modern historiography of the New Economic Policy makes it possible to assess the state of research on this science topic, identify the strengths and weaknesses of the historiographic process, and define promising areas of research. It is believed that the conducted analysis will help young researchers update their original scientific research.

Materials and Methods. The methodological approach to the analysis of literature, due to the presence of a vast number of publications, which makes a detailed historiographic analysis almost impossible, is based on a selection method, when the most authoritative publications are analysed, the assessments and conclusions of which have determined the angle of subsequent research. The second method is to focus on specific research areas that are clearly manifested in the modern historiographic process.

Results and Discussion. Modern historiography of the New Economic Policy is extensive both in thematic diversity and the degree of study of research issues. The study process continues; the New Economic Policy topics are far from exhausted and remain attractive to researchers. The re search process becomes methodologically multifaceted, more multidimensional in terms of sources, and interdisciplinary in content. The result of the modern historiographic process can be considered the development of a more realistic position in assessing the historical model of the New Economic Policy with all its elements.

Conclusion. The results of the study make it possible to give a realistic picture of the state of the modern historiographic process, identify new methodological approaches to the study of the New Economic Policy problems, expand the thematic diversity and pay attention to the problems in this historiographic segment.
Demographic profile of the “revolutionary turning point” generation of the Russian village in the first half of the 1920s
Authors: Ippolitov V. A. , Bezgin V. B.
Published: November 2024

Importance. The demographic portrait of peasantry in the first half of the 1920s is examined. The relevance of the study is due to the need for a comprehensive study of the Russian peasantry of the “revolutionary turning point” generation (born at the turn of the 19th and 20th centuries). The pur pose of the research is to provide a detailed demographic description of the specified age cohort of rural society during a period of large-scale socio-political upheavals.

Materials and Methods. The authors focus on the main demographic indicators: birth rate, mor tality, marriage rate, and natural population growth. In order to determine the factors that influ enced the model of demographic behaviour of peasants, statistical collections for the Voronezh, Oryol, Kursk, and Tambov provinces are analysed. These sources are characterised by the pres ence of objective data on the population with minimal ideological distortions. The paper uses a wide range of materials based on censuses, surveys, special studies, and observations. The works of prominent ethnographers of the 1920s are also considered.

Results and Discussion. The authors have analysed the demographic behaviour of the “revolu tionary turning point” generation during the new economic policy period. The influence of wars and revolutions on the family behaviour of peasants is studied. The features of marriage and di vorce are considered. The specifics of compensatory birth rate after a series of wars are examined. The main causes of mortality among peasants of the “revolutionary turning point” generation are established. The factors increasing life expectancy and decreasing the mortality rate of the rural population have also been determined.

Conclusion. Based on a wide range of sources, the conclusion is made about the contradictory model of demographic behaviour of peasants of this generation, which combined elements of tra ditionalism and modernist features.
Modern approaches to the study of collectivization in the context of modernization theories
Authors: Goncharova I. V. , Chuwardin G. S.
Published: November 2024

Importance. The key issue in Russia’s history has always been the agrarian question, which took the form of the collectivization of peasant agriculture in the 1930s. Late in the 20th and the first quarter of the 21st centuries, when a lot of new archive sources were involved in open circulation, the issue of transforming agrarian relations became the core of public and scholarly discourse. The purpose of the study is to analyse and systematise modern research approaches to the study of the collectivization process in the Soviet Union in the late 1920s–1930s in the context of modernization processes.

Materials and Methods. An interdisciplinary methodological approach is used in the research: the works of historians, sociologists, and cultural scientists on the problems of collectivization and modernization are analyzed. Methods of comparative and structural analysis are used in the study of historiography.

Results and Discussion. The publications of historians from the late 1980s to the 2020s devoted to “the great break” in the life of the Russian village are studied. Based on a comprehensive approach to the problem of collectivization, the versatility and interrelationships of various scientific views are highlighted; the research demonstrates that collectivization is not merely a local historical phenomenon but is a part of a broader, global process of modernization of Russia.

Conclusion. The agrarian issue of Russian history and historiography is a multifaceted topic essential for understanding the economic, social, and cultural processes of Russia. In the postPerestroika period, “the great break” has been re-evaluated. At first, it was heavily criticised, but later the objective reasons for the creation of the collective farm system were recognised. In modern historiography, collectivization is considered in the context of modernization of Russia, emphasizing the continuity of the pre-revolutionary and post-revolutionary periods.
History of economic and demographic development of the Chinese northeastern province of Liaoning (1954–1978)
Authors: Makeeva S. B.
Published: November 2024

Importance. Studying the Chinese province of Liaoning’s economic and demographic development history allows us to trace the origin of current problems related to the migration of the Chinese population to the eastern and south-eastern provinces and the decline in the birth rate throughout China. The economic and demographic development of Liaoning Province after the founding of the People’s Republic of China in 1949 until the start of the “reform and opening up” policy in 1978, was characterized by the processes of economic development and the formation of industrial infrastructure. The research aims to examine the history of the economic and demographic development of Liaoning Province in the context of the formation and functioning of northeast China's industrial base from 1954 to 1978.

Materials and Methods. The study uses materials from the population censuses of the People’s Republic of China for 1953, 1964; five-year plans (1953–1957, 1958–1962, 1966–1970, 1971–1975, 1976–1980); statistical collection on the industrial development of Chinese provinces from 1949 to 1989; statistical collections of Liaoning Province. The main research methods in preparing the study were historical-genetic and statistical.

Results and Discussion. In the process of reviewing the history of economic and demographic development of Liaoning Province from 1954 to 1978. several stages are identified: 1. 1953–1957 – economic and demographic development of Liaoning province during the implementation of the first five-year plan; 2. 1958–1966 – development in difficult conditions of industrial transformations; 3. 1966–1978 – development during the years of the “Cultural Revolution” and the transition to the policy of “reform and opening up”.

Conclusion. The formation of Liaoning as an important industrial base of China from 1953 to 1957. had an impact on strengthening the economic potential of the province and the growth of its population due to the migration influx of young qualified personnel from all over China to Liaoning. The unprecedented growth of steel enterprises, as well as three years of natural disasters (1959, 1960, 1961) were reflected in a decline in the birth rate and a decrease in the natural increase in the population of Liaoning Province in 1958–1966. During the Cultural Revolution, the development of Liaoning was accompanied by a decrease in the share of the metallurgical industry and an increase in mechanical engineering. The pace of technological industrial renewal slows down, and the number of skilled workers arriving in Liaoning declined. These processes and the introduction of family planning policies in China were reflected in a decrease in the birth rate and natural population growth in the province.
Escalation of the Palestinian-Israeli conflict: operation “Home and Garden”
Authors: Ermakov A. A. , Ryzhov I. V.
Published: November 2024

Importance. The escalation of the Palestinian-Israeli conflict, which acquired particular attention after the outbreak of war between Israel and the Hamas movement at the end of 2023, is examined. The purpose of the study is to identify the features of the Jennine invasion as a prerequisite for the conflict development towards large-scale escalation between Palestine and Israel.

Research methods. The research is based on the objectivity, historicism and a systematic approach principles. Along with general scientific methods, such as analysis and comparison, historical-comparative, retrospective, synchronous methods are used, without which it would be impossible to study the events that took place simultaneously in both parts of the Palestinian arena (in the Gaza Strip and the West Bank).

Result and Discussion. It is noted that the operation “Home and Garden”, as well as the events around it, clearly demonstrated the significant capabilities that West Bank radicals currently possess in the armed struggle against the Israelis, such as the ability to produce war weapons in large quantities on their own. The radicals have limited resources for military preparations, so the ability to manufacture means of armed struggle is necessary to effectively confront the Israelis. In addition, missile weapons can only be an addition to other, more necessary, means of armed struggle. Nowadays, the priority for operating in the West Bank radicals is the underground infrastructure deployment that can provide them with additional opportunity to maneuver forces and means during the confrontation with Israeli security forces.

Conclusion. It is noted that the operation “Home and Garden” is of particular importance due to the forces and means involved in its implementation and its results; it should be considered the main episode of the campaign in the Jenin area. The actions of the Israeli security forces weakened the radicals position, which subsequently simplified the maintenance of armed confrontation in the West Bank of Jordan at a level acceptable to Tel Aviv, while significant Israeli forces were involved in the fight against the radicals of the Gaza Strip and Hezbollah, and the possibility maneuvering of these forces and means was limited due to the synchronicity of the armed confrontation in the Palestinian and Lebanese directions.
Challenges and strategies in estimating soil organic carbon for multi-cropping systems: a review
Authors: Bai Zhiyuan , Zhang Datong , Wang Zechen , Harrison Matthew Tom , Liu Ke , Song Zhenwei , Chen Fu , Yin Xiaogang
Published: November 2024

Multi-cropping systems play a crucial role in global agricultural production. Accurately estimating the soil carbon sequestration capacity of multi-cropping systems is of significant importance for enhancing agricultural productivity, mitigating greenhouse gas emissions, and reducing carbon footprint. However, soil carbon cycling is more complex in multi-cropping systems compared with single-cropping systems, and existing assessment methods cannot accurately estimate soil carbon sequestration in multi-cropping systems with high operability. Here, we reviewed the accuracy and efficiency of the three primary global soil carbon assessment methods, including statistical models, process-based models, and the Intergovernmental Panel on Climate Change (IPCC) steady-state method. Our study concludes that it is difficult to simulate the dynamic evolution of soil organic carbon (SOC) using the statistical models, while the well simulation through process-based models demands a large amount of data. Additionally, the IPCC Tier 2 method cannot be directly applied to estimate SOC in multi-cropping systems due to mismatches in parameters and time steps. We suggest modifying the structures and parameters of the IPCC Tier 2 method by revising the inventory unit and redetermining the parameter values, which should efficiently address its bottleneck in estimating SOC for multi-cropping systems. Moreover, long-term experimental observations and multi-model ensemble simulations are beneficial for determining the parameter values to address the data deficiencies in IPCC Tier 2. This study aims to explore pathways for improving the accuracy of SOC estimation in multi-cropping systems and, thus, carbon footprint calculation worldwide.
ХАРКІВСЬКИЙ ЧАСОПИС «НОВА ГРОМАДА» В УМОВАХ РОЗГОРТАННЯ УКРАЇНСЬКОГО НАЦІОНАЛЬНО-ВИЗВОЛЬНИХ ЗМАГАНЬ НА СЛОБОЖАНЩИНІ В ЛИСТОПАДІ — ГРУДНІ 1917 Р.
Authors: Довбищенко М.
Published: November 2024

В статті досліджено редакційну політику харківського часопису «Нова Громада» в умовах розгортання Визвольних змагань українського народу в листопаді — грудні 1917 р. Розглянуто специфіку тогочасного українського політичного руху на Слобожанщині та проблему формування єдиного інформаційного простору, який би забезпечував поступ державотворчих сил у регіоні. Визначено політичне «Credo» членів редакційної колегії газети, які представляли українські соціалістичні партії Харківщини. Основну увагу приділено тематиці статей «Нової громади». Зокрема, набула широкого висвітлення тема культурно-національного відродження на Слобожанщині та повʼязана з цим проблема просвітянського руху та українізація освіти, обговорювалися перспективи економічного поступу й розвитку банківської справи, тощо. Водночас активно обговорювалися проблеми загроз нещодавно проголошеній Українській Народній Республіці та взаємодія з соціалістичними партіями Росії, передусім з більшовиками. Було зроблено висновок, що редакційна колегія часопису «Нова Громада» формувала інформаційну політику, яка сприяла культурно-національному руху на Слобожанщині, заохочувала розвиток кооперації та згуртовувала навколо себе прихильників Центральної Ради. Водночас редколегія й автори публікацій були носіями соціалістичних ідей з притаманними їм утопіями. Передусім це стосувалося тез щодо усуспільнення промислових підприємств та необхідності в конфіскаційній грошовій реформі. Великою помилкою був також класовий підхід до усвідомлення потенційних загроз Україні, нерозуміння сутності російського більшовизму та недооцінка його небезпек.

Siber Egemenlik Konusu
Authors: Kıllıoğlu Mehmet Erkan
Published: November 2024

Egemenlik kavramı, iktidar kavramı gibi devletin ortaya çıkışından bu yana gerek siyasetçileri, gerek devlet adamlarını gerekse de düşünürlerin üzerinde düşündüğü, yorum yaptığı, tanımlamaya ve kavramsallaştırmaya ve genel çerçevesini çizmeye çalıştığı kavramlardan birisi olmuştur. Zaman içerisinde devletin geçirdiği değişim ve gelişim süreci ile irtibatlı olarak gelişen egemenlik kavramı özellikle Westphalia uluslararası sistemi sonrasında ortaya çıkan ulus devlet merkezli yeni sistem sonrasında daha da ön plana çıkan ve üzerinde düşünülen bir kavram olmuştur. Düşünürleri, siyasetçileri ve devlet adamlarını meşgul eden bu kavram, modern çağda, özellikle iletişim alanında yaşanan gelişmeler ve Küreselleşme gibi süreçler sonrasında dünya siyasetinin değiştiği, dünyanın daha küçük ve ulaşılabilir hale geldiği günümüzde, sorgulanır ve tartışılır hale gelmiştir. Bu süreci aşmak adına Egemenlik kavramı da değişim geçirmiş, yeni dönemin şartlarına adapte olmak için, internet sayesinde sanal bir evrenin ortaya çıktığı ve hızla geliştiği bu dönemde karşısına çıkan meydan okumaları karşılamak adına Sanal-Siber Egemenlik olarak adlandırılan bir kavramla karşılık vermiştir.

Published: November 2024

In this forum article, we examine the state of the field of Peace and Conflict Studies in providing a platform to incorporate local knowledge to generate global insights. Many scholars in peace and conflict studies have traditionally relied on cross-national empirical analyses to investigate conflict dynamics, which can present opportunities for increased level of collaboration, methodological advancement, and interdisciplinary works. Whereas Western-oriented institutions and approaches serve as the locomotive of the production in the field, the vast majority of their data locates in non-Western contexts with diverse cultural, political, social, linguistic, and economic settings. Hence, the overarching theme of this forum emphasizes the benefits of an empirically-driven, methodologically rigorous research agenda that strongly incorporates local knowledge. We offer a platform to discuss the limits and prospects of Global North- South cooperation, the challenges of gathering dependable data, and the ways to overcome these issues while maintaining academic integrity and deepening our understanding of conflict dynamics. We believe that sustained investment in collaborative partnerships and capacity-building initiatives will be critical for unlocking the full potential of local expertise and insights in advancing knowledge-production and fostering peace and stability in conflict-affected areas.

Published: November 2024

At the late stage of field development, the reservoir pressure drops. For various reasons, liquid begins to rise into the bottomhole zone of the formation, which may entail a sharp drop in the gas well production rate and a reduction in the well life. There are many methods of flooded wells operating, among which the method of using foaming surfactants has recently become increasingly widespread. This paper examines the reasons for the influx of liquid into the wellbore, as well as the features of the use of foaming surfactants to intensify gas production from flooded wells. In addition, an overview was made of various types of foaming surfactants used to intensify gas production by removing liquid from flooded wells, their advantages and disadvantages, and the feasibility of using certain types of foaming surfactants was considered, depending on the mineralization of the liquid and the presence of gas condensate in its composition. An algorithm for selecting foaming surfactants to remove liquid from the bottomhole is presented. The requirements for foaming surfactant compositions are set forth. Processes occurring at application of foaming surfactants for liquid removal from wellbore are described. Parameters characterizing properties of foaming surfactants solutions and factors influencing foaming properties of surfactants are indicated. Methods of injecting aqueous solutions of surfactants into production wells are described. The technology of gas well bottomhole treatment with liquid surfactants, methods of process control, as well as problems that may arise when using surfactants are described.
PROPERTIES OF BITUMEN MODIFIED WITH ADHESIVE ADDITIVES BASED ON RENEWABLE RAW MATERIALS
Authors: Poliak Olha , Gunka Volodymyr
Published: November 2024

The main quality characteristics of road petroleum bitumen are: adhesive properties that determine the adhesion of binders to mineral materials; rheological properties that determine technological and operational parameters; physical and chemical properties that determine resistance to weather, climate and operational factors during the service life (aging resistance). Bitumen is the main binder of asphalt pavements, so it is the properties of bitumen that determine the performance of asphalt concrete. The adhesion of bitumen to mineral material, such as crushed stone or glass, is one of the main indicators in the design and construction of roads. This indicator determines the strength and service life of the road surface. Whereas a lack of cohesion can lead to significant damage to asphalt concrete. Since most distillation and oxidised bitumen have low adhesive properties, it is necessary to introduce adhesive additives to them. The most common method of improving the adhesion of bitumen binders to stone materials contained in asphalt mixtures is the use of adhesive additives (surfactants): cationic, anionic and non-ionic.
The problem of producing high-quality road bitumen is quite acute. There is an increasing number of studies aimed at the production of asphalt pavements from alternative renewable bioresources. That is why, in this paper, it is proposed to modify binding surfactants of plant origin. These surfactants are obtained by amidation of rapeseed oil. Such additives are profitable in terms of production, affordable, environmentally friendly and made from renewable raw materials, which are grown in sufficient quantities in Ukraine. The resulting additives were used to modify the bitumen and determine its adhesion to the surfaces of crushed stone and glass.

Published: November 2024

The article investigates the fly ash from Burshtyn TPP for its use as a component of binding raw material compositions for the production of small-piece concrete products. Based on the integrated characteristics of chemical and phase composition, it was found that the ash is ultra-acidic, is an amorphous substance and is characterized by low hydraulic activity. Calcium-containing additives (slag cement and/or hydrated lime) and an alkaline aggregate (soda solution) were used to activate the ash glass. The charges compositions using ash at the level of 75–90 wt. %, in which the type and amount of activator and the type of aggregate (alkaline solution or water) were subject to variation in order to optimize the technological parameters of the materials. For materials formed at a pressing pressure of 25 kgf/cm2 and hardened under steaming conditions, a positive effect of cement, alkaline aggregate and combined hardening activator on the properties of materials, their appearance and geometric dimensions was established. Such materials have a low level of mechanical properties; only certain charge compositions allow for a mechanical strength grade of M50 to M75. In order to improve the final mechanical strength of materials, the influence of pressing pressure, moulding moisture and hydrothermal treatment methods (steaming or parboiling) on the properties of materials of individual compositions was investigated. It has been determined that increasing the pressure up to 300 kgf/cm2 and autoclave treatment of semi-finished products can significantly improve the level of mechanical properties. The rational compositions of binder compositions with a high degree of fly ash use (75 and 77 wt. %) were determined, on the basis of which water-resistant samples of asphalt concrete grades M 125 and M200 in terms of mechanical strength and grade F25 in terms of frost resistance were obtained by semi-dry pressing. The materials are recommended for the manufacture of products for the construction of sidewalk elements, as well as wall small-piece concrete products.

A sample of 1897 digital panoramic radiographs were evaluated to determine the frequency of PIR and its covariates of location, depth, and inclination of the affected teeth. The authors’ calibration was performed before the study. The intraoperator agreement was determined by calculating the Kappa coefficient (0.72, CI 0.67-0.76). The radiographs were evaluated by the study's principal author (IEP), and the data were collected in a form designed for the study. The statistical association was determined using the Chi-square test, with a confidence level of 95%, and a p-value of less than 0.05 was considered significant. Results: The frequency of PIR was 3.95%, with no statistically significant difference between sexes (p>0.05). The most common findings were PIR in the lower right second molar (32.5%), a singular defect (89.3%), central location (44.5%), and superficial dentinal involvement (83.1%). These results aligned with existing literature. Conclusions: Our results describe the epidemiological profile of PIR in the present sample as a single radiolucent and small (grade I) defect located centrally in the coronal dentin, often affecting posterior lower teeth with a frequency lesser than 5%. These findings provided valuable insights for clinicians and researchers regarding the frequency and characteristics of PIR in Peruvian patients.

Uno de los impulsores de cambio que afecta a los humedales costeros peruanos es el crecimiento descontrolado de plantas acuáticas invasoras. Esta investigación tuvo como objetivo generar ecuaciones que expliquen la producción de biomasa de una población de P. stratiotes en el humedal Santa Rosa - Chancay - Lima y, a partir de ello, proponer un sistema de producción de compost y vermicompost. Se registró la biomasa de P. stratiotes (octubre del 2022 - febrero del 2023) para obtener modelos matemáticos que expliquen su evolución en el tiempo. Asimismo, se construyeron sistemas de producción de compost usando ocho diferentes tecnologías de compostaje tradicional y vermicospostaje; en cada caso se evaluó la calidad y eficiencia de compost obtenido. Los mejores modelos para el crecimiento de la biomasa fueron a) para los meses de invierno el modelo de descenso exponencial (R2=0.97; coef. De correl=0.99; Error st. =0.11) y b) para los meses de verano el modelo geométrico (R2=0.80; coef. De correl=0.90; Error st. =0.55). El compost de mejor calidad y eficiencia fue el de compostaje tradicional, con 30% de biomasa y con adición del acelerador microbiano. El crecimiento de P. stratiotes registrado en tiempo de duplicación tanto en verano (17.70 días) e invierno (20.64 días), sugieren realizar cuatro extracciones al año, obteniendo una producción total de cuatro toneladas de compost, bajo el modelo de descenso exponencial para un manejo controlado del crecimiento de la biomasa de P. stratiotes en la laguna principal.

Cortez (2023) destaca que el sistema de salud pública en Perú ha tenido problemas persistentes en liderazgo, financiamiento y monitoreo epidemiológico, afectando la calidad de los servicios. El organismo autónomo Controlaría General de la Republica ha implementado estrategias de control para mejorar el desempeño de los servidores y asegurar la calidad del servicio. Sin embargo, muchos servidores no comprenden la importancia del control interno, lo que lleva a brechas en comunicación y eficiencia, y a una atención deficiente. El estudio del Hospital Vitarte en el distrito Ate, durante 2022, utilizó una encuesta con 63 participantes para examinar la relación entre el Control Interno y la Calidad del Gasto. Los resultados indicaron que una mayor aplicación de controles internos se asocia significativamente con una mejora en la calidad del gasto, sugiriendo que fortalecer estos controles puede elevar la calidad del servicio en el hospital.

Objetivo: Determinar si una exposición prolongada a pantallas digitales en los estudiantes de medicina humana de la UCSUR aumentaría el riesgo de padecer el Síndrome Visual Informático. Métodos: Se realizó un estudio observacional analítico transversal en estudiantes de medicina de la Universidad Científica del Sur, usando muestreo no probabilístico por conveniencia. El Síndrome Visual Informático se evaluó virtualmente con el cuestionario SVI-Q en Google Forms, considerando características demográficas, exposición a pantallas, medidas preventivas y enfermedades oculares. Los resultados se analizaron con Stata 18 y el estudio fue aprobado por el Comité de Ética de la UCSUR. Resultados: La investigación encontró que la mayoría de estudiantes son mujeres (64.08%), con una mediana de edad de 20 años. El 59.22% usa lentes, principalmente con marco, un 55.83% tiene miopía y 48.54% astigmatismo. El análisis reveló que el uso de dispositivos por 4 horas o más durante clases virtuales aumenta significativamente el riesgo de padecer Síndrome Visual Informático (SVI). Se encontraron factores de riesgo significativos como uso prolongado de aparato electrónico, la computadora portátil y fijar la mirada en sitios lejanos. Conclusiones: La exposición prolongada a pantallas digitales aumenta significativamente el riesgo de Síndrome Visual Informático en estudiantes de medicina de UCSUR, especialmente en mujeres y miopes. Factores clave incluyen el uso extendido de aparatos electrónicos como las computadoras portátiles y fijar la mirada en sitios lejanos.
Estilos de aprendizaje y estrategias de enseñanza docente en estudiantes de posgrado de segunda especialización en administración y gestión en salud en universidades de Lima metropolitana – Perú

La práctica rutinaria donde el profesor planea los temas, transmite información y luego evalúa; los estudiantes oyen y siguen instrucciones; es una forma de enseñanza no coherente con los estilos de aprender del estudiantado que dificultan la generación de aprendizajes significativos. Esto se refleja en bajo nivel de competitividad, indisposición para el conocimiento y poca capacidad en el desempeño profesional. En este sentido, el objetivo de la investigación consistió en determinar la relación entre los estilos de aprendizaje y las estrategias de enseñanza en los estudiantes de posgrado. La investigación se sustenta en un diseño de estudio no experimental y transversal. El nivel o alcance del estudio es correlacional. La muestra la constituyeron 92 estudiantes. Para la recolección de los datos se utilizó el Cuestionario CHAEA y el cuestionario de Estrategias de Enseñanza. Para la prueba de hipótesis se empleó la prueba no paramétrica de Spearman. Se concluyó que existe relación positiva entre los estilos de aprendizaje y las estrategias de enseñanza. Asimismo, el estilo de aprendizaje predominante fue el reflexivo y las estrategias de enseñanza predominante fueron las de problematización. El estudio aporta insumos para la elaboración de estrategias didácticas que fortalezcan los estilos de aprender de los estudiantes.
