The social challenges of modern globalization caused by the COVID-19 pandemic have led to significant changes in the development of economic systems at various levels. Social development in the direction of a post-industrial society activates the introduction of digital technologies in all areas of life, which requires paying attention not only to the innovative component of its development, but also to the intellectual one, since the digital transformation requires a constant updating of knowledge; this determines the purpose of this scientific study. The article aims to highlight the influence of intellectual and innovative determinants in the development of regions under current conditions, which are outlined by the manifestations of the COVID-19 pandemic and global digitalization in the development of economic systems. The foundation of the system approach methodology made it possible to distinguish the development trends of the regions in the conditions of the COVID-19 pandemic and global digitalization. It is proposed to create guidelines for the intellectual and innovative promotion, determinants of the development of the regions in the conditions of the COVID-19 pandemic and global digitalization, according to the socioeconomic, scientific-technological, organizational and legal components. The main guidelines of efforts to increase the role of intellectual and innovative determinants in the development of regional systems in the conditions of the COVID-19 pandemic and global digitalization have been tested, taking into account the principles of complexity, integrity, flexibility, efficiency and long term.

Objetivos: Evaluar la presión arterial (PA) en escolares del estado Táchira e investigar su asociación con el índice de masa corporal (IMC), dado que constituyen factores de riesgo cardiovascular. Métodos: Se estudiaron 84 escolares, de 9,05±1,36 años, 57,14% femeninas, 42,86% masculinos. Se tomó PA, medidas antropométricas; se calculó IMC. Considerando sobrepeso IMC >p90, obesidad >p97 según curvas venezolanas; pre-hipertensión ≥p90, hipertensión 1 ≥p95, usando valores adaptados del NHBPEP. Resultados: 3,6% presentó pre-hipertensión sistólica, 4,8% PA diastólica elevada (3,6% pre- hipertensión y 1,2% hipertensión estadio 1). Hubo correlación positiva y significativa entre IMC y PA (p=0,0001). Se observó PA ≥p90 en 28,6% de los niños obesos versus 4,8% de los normopeso. No hubo asociación del IMC y la PA con género ni edad. Conclusiones: Se encontró PA elevada en escolares, demostrándose asociación estadística entre PA alta y exceso de IMC, ambas ocasionan daño orgánico, por ende la importancia de su evaluación, detección e intervención precoz.

La contextualización de la enseñanza consiste en adaptar los contenidos, estrategias y recursos a la realidad social, cultural y ecológica de los estudiantes; también, implica desarrollar las temáticas y sesiones de aprendizajes, utilizando ejemplos de la vida cotidiana. El objetivo de esta investigación fue caracterizar la enseñanza contextualizada para el aprendizaje de las Ciencias Naturales en los estudiantes de educación secundaria. La metodología utilizada en este estudio fue descriptiva, el diseño de campo, no experimental y transversal. La población estuvo constituida por 36 docentes de instituciones públicas de educación secundaria, del municipio Mara, estado Zulia, Venezuela. Los resultados expresan que los tipos de estrategias que favorecen el aprendizaje, los elementos que benefician la contextualización de los contenidos y las habilidades que contribuyen al aprendizaje de Ciencias Experimentales, son poco eficientes, por lo que se concluye, que los docentes que enseñan estas asignaturas utilizan en pocas oportunidades estrategias adaptadas al contexto que permiten promover el aprendizaje.

Several studies have been carried out related to the analysis of the relationship with respect to the dynamic properties of f and its hyperextension ̄f. However, the literature regarding the analysis of the effects of individual and collective chaos on their behaviour is scarce. Therefore, in this article several conjectures and questions are established according to the affectation of individual chaos in an ecosystem and its chaotic behaviour within the dynamics of this ecosystem, but as a whole. Thus, in the first instance, an introduction to the conceptualization of topological transitivity, chaos in the Devaney sense and how they are specified in continuous linear operators arranged in a Fréchet space (hypercyclic operators) will be established. In addition, the different notions of chaos that can occur depending on the relationship of the function, and its hyperextension will be described, to finally corroborate the present chaos with greater force than Devaney’saccording to the strong periodic specification property, the same one that applies to both f and a ̄f with the purpose of verifying the directionality in which individual and collective chaos can occur.

The purposeof the proposed research is to create a metaphysical portrait sketch of Melitopol in the symbolic circle "honey -milk -water" in the context of attracting symbolic resources problem in tourism.In an intensive way, and following thestrengtheningof homo viator phenomenon in the global world, research in the touristic field and philosophy of tourism are increasingly turning their attention to the "internal resource", including in this concept, in addition to natural and cultural-historical, also symbolic resource. The work uses such methods as dialectical and metaphysical, the principle of comprehensiveness of research, the general logical method, and other methods of scientific research. Tourist legend as an applied direction can become an effective marketing mechanism, as a result of which it is possible, using a symbolic resources variety and tools, to create humanitarian and social development perspectives, agreed and identified through analysis of mythological structures and conceptual shells for harmonious and effective development of these territories. In this aspect, tourism as oneof the mass culture branches will produce tourist flows directed to previously elaboratedterritorial brands.

The relevance of this scientific research is justified by the increased attention that the economic community pays to economic security, for the development of microeconomic systems in modern conditions of uncertainty, caused by global challenges, as a result of the COVID-19 pandemic. The purpose of the study is to identify the principles of the formation of an adaptive management system of economic security of enterprises in the conditions of the COVID-19 pandemic. The authors founded the methodological basis for the formation of the adaptive management system of the economic security of companies, based on the identification of the systemic approach and specific principles of compliance, duality and feedback, as well as the functions of adaptive management. The conducted research makes possible to generalize that the formation of a system of adaptive management of the economic security of enterprises in the COVID-19 conditions is a special type of management activity, which involves the use of a wide range of measures and tools for making effective management decisions, which are characterized by timeliness, flexibility, creativity and innovation.

La floculación es un método de precipitación que retiene los sólidos suspendidos, liberando aguas grises con una carga orgánica menor. El polvo de moringa tiene un efecto floculante y en este caso se evaluó su efecto entre las poblaciones bacterianas, especialmente las de importancia en salud pública. El estudio se realizó en la Ciudad de Reynosa, Tamaulipas, que tiene dos canales que conducen agua para uso urbano y agrícola. Cuatro sitios fueron muestreados, dos en la ciudad y los otros en la periferia de la ciudad. Las muestras de agua recolectadas en cada punto fueron divididas en dos. Un lote fueron los controles y al otro se les agregó polvo de moringa. Posteriormente, en todos los lotes se realizó una extracción de ADN para análisis metagenómico de la biota presente. Los resultados mostraron que hay un efecto floculante en las muestras de agua y que con el tratamiento se alteran las poblaciones microbianas; finalmente, se observa que las poblaciones de bacterias de importancia en salud pública no son retiradas con el tratamiento.

The objective of the article is to investigate the theoretical and practical aspects of digital medical care in the context of the challenges and opportunities of technological progress, and to outline the main guidelines for the development of digital technologies in the field of Medicine. The methodology consists in the use of a systematic method, which offers the achievement of sustainable development of digital technologies of medical institutions; the proposal is based on the adaptability and flexibility of the management structures of medical institutions, capable of using the available data and digital technologies to provide assistance to the population; a synergistic method based on self-organization and the search for the bases of self-organization, which can help medical institutions to overcome the crisis and instability. The study shows that the digital change is increasingly visible in Medicine. Thanks to digital technologies and tools in Medicine, particularly through eHealth technologies, prevention, diagnosis, treatment, monitoring and administration have been improved. The problems of digitization are discussed not for themselves, but for the improvement of medical care, digital health in the context of the challenges and opportunities of technological progress, the formation of a new concept of digital technologies in the field of health.
