Дистанционное образование в России в контексте обучения иностранным языкам

Every year the interest of youth in a foreign language as a means of international communication increases. New professions arise that require knowledge of a foreign language. Knowledge of a foreign language is a mandatory requirement for business communication and running anywhere in the world, evidence, and guarantee of competitiveness, professional socialization of the modern young generation. One of the priority tasks of the language training system is the improvement of teaching methods, the search for innovative methods, and advanced technologies for teaching languages. The article describes the current trends in Russian education, which are associated with the spread of distance education. It is proved that distance education is becoming increasingly important in terms of language training. It is shown that modern trends in education are associated, first of all, with the need to overcome the contradictions between the content of training and the requirements for the personality of the future specialist, the traditional organization of the educational process and the patterns of interpersonal and intercultural interaction.Cada año aumenta el interés de los jóvenes en un idioma extranjero como medio de comunicación internacional. Surgen nuevas profesiones que requieren el conocimiento de un idioma extranjero. El conocimiento de un idioma extranjero es un requisito obligatorio para la comunicación empresarial y la ejecución en cualquier parte del mundo, evidencia y garantía de competitividad, socialización profesional de la generación joven moderna. Una de las tareas prioritarias del sistema de capacitación en idiomas es la mejora de los métodos de enseñanza, la búsqueda de métodos innovadores y las tecnologías avanzadas para la enseñanza de idiomas. El artículo describe las tendencias actuales en la educación rusa, que están asociadas con la difusión de la educación a distancia. Está comprobado que la educación a distancia se está volviendo cada vez más importante en términos de capacitación en idiomas. Se muestra que las tendencias modernas en educación están asociadas, en primer lugar, con la necesidad de superar las contradicciones entre el contenido de la capacitación y los requisitos para la personalidad del futuro especialista, la organización tradicional del proceso educativo y los patrones de interpersonal e interacción intercultural. С каждым годом увеличивается интерес молодежи к иностранному языку как средству международного общения. Появляются новые специальности, требующие владения иностранным языком.Знание второго и последующих языков – это обязательное требование для делового общения и ведения бизнеса в любой точке мира, свидетельство и залог конкурентоспособности, профессиональной социализации современного молодого поколения.Одними из приоритетных задач системы языковой подготовки являются совершенствование методов обучения, поиск инновационных методов и передовых технологий обучения языкам.В данной статье описываются современные тенденции российского образования, связанные с распространением дистанционного обучения. Доказывается, что дистанционное обучение приобретает все большее значение в плане языковой подготовки. Показано, что современные тенденции в образовании связаны, в первую очередь, с необходимостью преодоления противоречий между содержанием подготовки и требованиями к личности будущего специалиста, традиционной организацией образовательного процесса и закономерностями межличностного и межкультурного взаимодействия

Influence of substances with acid pH on composite resins microhardness

Resin composites are aesthetic restorative materials widely used in Dentistry and changes in pH can promote amendments in composite surface, compromising their initial characteristics. The aim of this study was to evaluate, in vitro, the effect of low pH beverages on two commercially available materials, the composite resins ICE (SDI) and Durafill VS (Heraeus Kulzer). The materials were evaluated for surface microhardness obtained by Vickers microhardness testing. Fifteen samples were prepared with 11 mm diameter and 2 mm thick, each restorative material. The samples were kept in storage conditions of the following substances: Gatorade ® (pH 2,9); Coca- Cola ® (pH 2,2) and distilled water (pH 6,0; control group) under temperature of 37 ° C, and the environment of immersing exchanged every 24 hours. Five samples of each material were immersed in the beverages tested and monitored for periods of 24 hours, 7, 14 and 21 days. The results were submitted to multifactorial analysis of variance and Tukey test. There were statistically significant differences (p 0.05) for factors environment, material and time, and for the interaction between them. The distilled water resulted in higher values of microhardness, followed by Coca-Cola® and Gatorade®. The highest values of microhardness were obtained at baseline, followed by 7, 14 and 21 days. There was no statistically significant difference (p 0,05) between the times of 14 and 21 days. It was concluded that the nanocomposite better results and that the acidic pH associated with progressive immersion time significantly alter the microhardness of the composites evaluated

The price competition simulation at the trading market in the presence of electronic and traditional trade

In the present work, an attempt has been made to apply economic and mathematical methods for the simulation of electronic trading market operation based on price competition between e-trade companies and traditional trade enterprises. The developed price competition model based on the concept of symmetric product differentiation. The results obtained in the present investigation demonstrate that in a mixed strategy, firms sell products at different prices, depending on the price strategy or the volume release strategy. The company that sets the volume, sells more, but at a lower price than its competitor which sets prices. The influence of strategic output exceeds price influence. Thus, the company that sets prices, falls into an unfavorable situation and receives lower profits compared with its competitor with the strategy for the volume of production. The company that has decided to introduce electronic trading technology initially will bear losses

Crystal structure of {μ-6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolato}(methanol)(nitrato)nickel(II)sodium

In the molecular structure of the title compound, [NaNi(C18H18N2O4)(NO3)(CH3OH)], the Ni2+ ion has a slightly distorted square-planar coordination environment defined by two N and two O atoms which belong to a Schiff base ligand, viz. 6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolate. Seven O atoms form the coordination environment of the Na+ ion: four from the Schiff base ligand, two from a bidentate chelating nitrate anion and one O atom from a coordinating methanol molecule. In the crystal, the bimetallic complexes are assembled into chains along the b-axis direction via weak C—H...O hydrogen-bond interactions. Neighbouring chains are in turn connected through bifurcated O—H...O hydrogen bonds that involve the coordinating methanol molecules and the nitrate anions, and through π–π stacking interactions between phenyl rings of neighbouring molecules
