Semantic explication of the phenomenon of "continuing education": the essence, purpose, functions, stages, manifestation at the levels of principle and process
Authors: Двоеглазов С.И. , Забайкин Ю.В.
Published: December 2022

В 70-х годах ХХ века непрерывное образование в ранге прогрессивной идеи приобрело законодательную определенность в ряде документов ЮНЕСКО и в законе США (Lifelong Learning Act; 1976 г.) как обучение в течение жизни. На протяжении 70-90-х годов ХХ века непрерывное образование практически реализовывалось на основе принципов концепции Т. Хюсена (Husen T. The Learning Society. L.; Methuen, 1974 г.) "Общество, которое учится" (learning society). Выделением доминирующего акцента в раскрытии сути непрерывного образования как сложного феномена предусмотрено акцентирование внимания на рассмотрении непрерывного образования и как принципа, и как процесса. Детализируем указано. В частности, непрерывное образование, выступая важнейшим социально-педагогическим принципом, "отражает современную тенденцию построения образования как целостной системы, которая направлена на развитие личности и составляет условие социального прогресса. По сути, речь идет о новом взгляде на образование, о новом подходе к пониманию значения образования в современной жизни". Рассмотрение непрерывного образования, как процесса, требует определения ряда принципов, с соблюдением которых выстраивается непрерывное образование.

In the 70s of the twentieth century, continuing education in the rank of a progressive idea acquired legislative certainty in a number of UNESCO documents and in the US law (Lifelong Learning Act; 1976) as lifelong learning. Throughout the 70-90s of the twentieth century, continuing education was practically implemented on the basis of the principles of the concept of T. Husen (Husen T. The Learning Society. L.; Methuen, 1974) "The society that learns" (learning society). Highlighting the dominant emphasis in the disclosure of the essence of continuing education as a complex phenomenon provides for an emphasis on the consideration of continuing education both as a principle and as a process. We detail the specified. In particular, continuing education, acting as the most important socio-pedagogical principle, "reflects the current trend of building education as an integral system that is aimed at personal development and is a condition for social progress. In fact, we are talking about a new look at education, a new approach to understanding the importance of education in modern life." The consideration of continuing education as a process requires the definition of a number of principles, in compliance with which continuous education is built.

Published: December 2022

A ‘top down’ scaffold remodelling approach to library synthesis was applied to spirotricyclic ureas prepared by a complexity-generating oxidative dearomatisation. Eighteen structurally-distinct, sp3-rich scaffolds were accessed from the parent tricycle through ring addition, cleavage and expansion strategies. Biological screening of a small compound library based on these scaffolds using the cell-painting assay demonstrated distinctive phenotypic responses engendered by different library members, illustrating the functional as well as structural diversity of the compounds.

Authors: P.S. Leitão Maria Inês , Turos-Cabal Maria , Sanchez-Sanchez Ana Maria , Gomes Clara , martin fernandez vanesa , Herrera Federico , Petronilho Ana
Published: December 2022

Platinum (II) complexes bearing N-heterocyclic carbenes based guanosine and caffeine have been synthesized by unassisted C-H oxidative addition, leading to the corresponding trans-hydride complexes. Platinum guanosine derivatives bearing triflate as counterion or bromide instead of hydride as co-ligand were also synthesized to facilitate correlation between structure and activity. The hydride compounds show high antiproliferative activity against all cell lines (TC-71, MV-4-11, U-937 and A-172). Methyl Guanosine complex 3, bearing a hydride ligand, is up to 30 times more active than compound 4, with a bromide in the same position. Changing the counterion has no significant effect on antiproliferative activity. Increasing bulkiness at N7, with an isopropyl group (compound 6), allows to maintain the antiproliferative activity while decreasing toxicity for healthy cells. Compound 6 leads to an increase in endoplasmic reticulum and autophagy markers on TC71 and MV-4-11 cancer cells, induces reductive stress and increases glutathione levels in cancer cells but not in healthy cell HEK-293.
Deep Reactive Ion Etching of Cylindrical Nanopores in Silicon for Photonic Crystals
Authors: Goodwin Melissa J , Harteveld Cornelis A M , de Boer Meint J , Vos Willem L
Published: December 2022

Periodic arrays of deep nanopores etched in silicon by deep reactive ion etching are desirable structures for photonic crystals and other nanostructure for silicon nanophotonics. Previous studies focused on realizing as deep as possible nanopores with as high as possible aspect ratios. The resulting nanopores suffered from structural imperfections of the nanopores, such as mask undercut, uneven and large scallops, depth dependent pore radii and tapering. Therefore, our present focus is to realize nanopores that have as cylindrical as possible shapes, in order to obtain a better comparison of nanophotonic observations with theory and simulations. To this end in our 2-step Bosch process we have improved the mask undercut, the uneven scallops, pore widening and positive tapering by optimizing a plethora of parameters such as the etch step time, capacitively coupled plasma (ion energy) and pressure. To add further degrees of control, we implemented a 3-step DREM (deposit, remove, etch, multistep) process. Optimization of the etching process results in cylindrical nanopores with a diameter in the range between 280 and 500 nm and a depth around 7 µm, corresponding to high depth-to-diameter aspect ratios between 14 and 25, that are very well suited for the realization of silicon nanophotonic structures.

Authors: Álvarez-Yebra Rubén , López-Coll Ricard , Galán-Masferrer Pere , Lledó Agustí
Published: December 2022

We report a chiral deep cavitand receptor based on calix[5]arene stabilized by a cooperative network of hydrogen bonds and having a highly flexible structure. The dynamic features of the host have been studied by 1H NMR spectroscopy, revealing a bowl inversion motion that is slow in the NMR time scale. The cavitand displays enantioselective molecular recognition with a series of chiral quaternary ammonium salts, providing unprecedented stability ratios between the corresponding diasteromeric host-guest complexes. Molecular dynamics simulations corroborate the higher flexibility of the new host and the emergence of superior induced fit behavior with regards to resorcin[4]arene derived self-folding cavitands.

Solid ofloxacin-methylxanthines complexes were prepared by co-precipitation method. In vitro transport studies were performed and the samples were analyzed by HPLC method. In situ intestinal absorption of drugs was performed in Wistar Albino rats by rat gut technique.Results Solubility of ofloxacin was enhanced in presence of methylxanthines. Stability constants of caffeineofloxacin and theophylline-ofloxacin complexes were found to be 10.5 and 9.3 litremol respectively. These complexes belong to class lsquotype Arsquo and sub-class lsquoAL rsquo. Melting point FTIR and DSC results confirm the formation of complexes between methylxanthines and ofloxacin. In vitro transport studies reveal that methylxanthines were not readily available for transportation in presence of ofloxacin due to their complex form. Transport of theophylline 0.01 min-1 is twice faster than that of the caffeine 0.0046 min-1. In situ absorption studies indicated that the absorption of methylxanthines was differed in presence of ofloxacin and vice versa and their absorption followed zero order kinetics. Absorption rate constants of caffeine theophylline and ofloxacin were 4.44 5.25 and 3.7 h-1 respectively.Conclusion Regression and statistical results supported the significant interactions between ofloxacin and methylxanthines which are noteworthy for pharmacotherapy

Oscillations of a System of Rigid Bodies Partially Filled with Viscous Fluids Under the Action of an Elastic Damping Device
Authors:   V. I. Vernadsky Crimean Federal University, Forduk K. V.
Published: December 2022

In this paper, we investigate the linearized two-dimensional problem on small motions of a system of rigid bodies partially filled with viscous incompressible fluids and connected in series by springs. The first and last bodies are attached by springs to two supports with a given law of motion. The trajectory of the system is perpendicular to the direction of gravity, and the damping forces acting on the hydrodynamical system are generated by the friction of bodies against a stationary horizontal support. For the described system, the law of total energy balance is formulated. Using the orthogonal projection method and a number of auxiliary boundary problems, the original initial-boundary value problem is reduced to the Cauchy problem for a first-order differential-operator equation in the orthogonal sum of some Hilbert spaces. The properties of operator matrices, which are coefficients of the obtained differential equation, are investigated. A theorem on the unique solvability of the resulting Cauchy problem on the positive semi-axis is proved. On the basis of the proved theorem, sufficient conditions for the existence of a strong with respect to time solution of an initial-boundary value problem describing the evolution of a hydrodynamical system, are found. From a mathematical point of view, the system under consideration is a finite-dimensional perturbation of the well-known S.G. Krein’s problem on small motions of a viscous fluid in an open vessel.

The problem of guaranteed estimation with geometrically bounded initial states and integrally limited disturbances is considered under delay information in the measurement equation. At the additional assumptions the problem is reduced to the creation of the reachable set of a special system. A discrete multistage system is specified for which the information set converges in Hausdorff’s metric to the corresponding information set of the continuous system when the diameter of partition is reduced. A numerical example is given.

The paper continues a long series of our research and considers a secondorder nonlinear evolutionary parabolic system. The system can be a model of various convective and diffusion processes in continuum mechanics, including mass transfer in a binary mixture. In hydrology, ecology, and mathematical biology, it describes the propagation of pollutants in water and air, as well as population dynamics, including the interaction of two different biological species. We construct solutions that have the type of diffusion (heat) wave propagating over a zero background with a finite velocity. Note that the system degenerates on the line where the perturbed and zero (unperturbed) solutions are continuously joined. A new existence and uniqueness theorem is proved in the class of analytical functions. In this case, the solution has the desired type and is constructed in the form of characteristic series, the convergence of which is proved by the majorant method. We also present two new classes of exact solutions, the construction of which, due to ansatzes of a specific form, reduces to integrating systems of ordinary differential equations that inherit a singularity from the original formulation. The obtained results are expected to be helpful in modeling the evolution of the Baikal biota and the propagation of pollutants in the water of Lake Baikal near settlements
Regularización de los asentamientos informales a partir de niveles de sostenibilidad
Authors: Camargo Mora Maria Gabriela , González Macas Diego Javier
Published: December 2022

La sostenibilidad urbana es aquella que ofrece calidad de vida a sus habitantes sin poner en riesgo los recursos y el bienestar actual y futuro de la población, además procura la justicia social. Las dimensiones que intervienen para generar espacios sostenibles son la económica, la social y la ambiental, cuya interacción persigue la eficiencia, la equidad y la habitabilidad. Los asentamientos informales en una ciudad forman parte integrante de la trama urbana y registran diferentes niveles de sostenibilidad generados por desigualdades en las condiciones de integración espacial, emplazamiento, acceso a infraestructuras en red, equipamientos, servicios, empleos e ingresos, tenencia de la tierra y de la vivienda, entre otros. Estas desigualdades generan barreras marcadas que dificultan la gestión municipal en el proceso de regularización y consolidación de los polígonos informales, además limita que las personas allí localizadas asciendan socialmente, se integren a las dinámicas territoriales y logren mayores niveles de bienestar. A esto se suma, la ausencia de procedimientos claros de gestión y administración local de los asentamientos informales que limita identificar las problemáticas, las potencialidades de sus realidades para orientar el proceso de regularización y consolidación, la mitigación de vulnerabilidades y riesgos. Ante esta realidad surge la interrogante ¿Como los niveles de sostenibilidad de los asentamientos informales pueden orientar las políticas de regularización y consolidación? Medir la sostenibilidad en el total de asentamientos informales en un área urbana mediante el  cálculo de índices parciales e índice global de sostenibilidad permite identificar los problemas críticos y las desigualdades entre ellos, jerarquizarlos, priorizarlos y formular estrategias y actuaciones de una manera más acertada, dando prioridad a aquellos asentamientos en situación más crítica. Conocer los niveles de sostenibilidad de los asentamientos informales facilitan la gestión y regularización, en una acción conjunta de la municipalidad con las comunidades. Es una estrategia válida para orientar los procesos de  regularización, su consolidación y orientar inversiones.
La responsabilidad jurídica de la inteligencia artificial desde el derecho clásico

El presente trabajo tuvo como objetivo analizar las diferentes posiciones teóricas que en el mundo contemporáneo se establecen respecto la responsabilidad jurídica que se le atribuye a los sistemas de IA a partir de hechos acontecidos o ejecutados por estos algoritmos, considerando su autonomía en la toma de decisiones a partir de su aprendizaje autónomo. Si bien el desarrollo de la IA debiera dotar a la humanidad de incontables beneficios, cuando existe afectación, daño o puesta en peligro de bienes jurídicos protegidos por el derecho se hace necesario determinar sobre quién recae la responsabilidad jurídica si la decisión que causó el agravio fue del sistema de Inteligencia artificial.

En 2008 se argumentó que los contextos institucionales de las economías emergentes difieren de las economías avanzadas, las cuales configuran la acción emprendedora. En ese sentido, se revisó 60 artículos sobre el emprendimiento en las economías emergentes y se descubrió que en efecto las débiles estructuras institucionales pueden influir en el comportamiento emprendedor, también se encontró que las teorías existentes sobre el emprendimiento dejan vacíos al intentar explicar el fenómeno en países caracterizados por elevados niveles de desigualdad, inseguridad y entornos institucionales llenos de corrupción. Como resultado se ofrecen algunas orientaciones para futuras investigaciones sobre el emprendimiento en los mercados emergentes.

Formação sociocientífica deve ser entendida como a capacidade de relacionar o conhecimento químico com a realidade social, refletindo sobre as inter-relações ciência e tecnologia dentro da sociedade, buscando, assim, formar cidadãos críticos e aptos a uma tomada de decisão pessoal e social quanto a situações-problema relacionados com a Ciência e a Tecnologia. Nossa pesquisa teve como questão norteadora perceber se as licenciaturas em Química trabalham a formação de professores numa perspectiva sociocientífica como meio de diálogo entre a formação científica e sua relação com o contexto social, proporcionando a ampliação para além do modelo da racionalidade técnica, instituído historicamente. Nosso objetivo foi investigar elementos constitutivos de uma perspectiva sociocientífica na formação de professores nas licenciaturas em Química, visando identificar uma integração e articulação dessa formação com os saberes e práticas da formação docente. Nossa pesquisa foi do tipo qualitativa e escolhemos como método o Discurso do Sujeito Coletivo (DSC), de forma aproximada que consiste na junção do discurso de cada sujeito participante da pesquisa, suscitando uma síntese discursiva, que representa o pensamento qualitativo da coletividade, apresentando de forma simbólica o que pensa o coletivo social dos sujeitos da pesquisa. Os Locais de pesquisa foram as Licenciaturas em Química de duas Universidade uma Federal e outra Estadual. Observamos que a formação de professores licenciados em Química privilegia a racionalidade técnico-instrumental e os saberes científicos disciplinares, não dialetizando de forma substancial e contínua esses componentes com a perspectiva sociocientífica e crítica, nos processos formativos.

Feiras de ciências têm sido consideradas importantes espaços não formais de educação de ciências. Neste estudo, buscamos compreender a visão que expositores das primeiras feiras de ciências no Brasil, em São Paulo, nas décadas de 1960 e 1970, têm sobre as feiras de ciências em que participaram e o significado que tais feiras tiveram em suas trajetórias. Realizamos 15 entrevistas com 12 homens e 3 mulheres que tinham entre 10 e 18 anos de idade. Os entrevistados apontam que as feiras de ciências foram experiências positivas, com oportunidades de atividades práticas e protagonismo por parte dos alunos. Os entrevistados associaram a experimentação como uma parte fundamental do método científico e mencionaram o papel motivador que os professores de ciências tiveram no seu ensino e sua participação nas feiras. Entre os seis entrevistados que seguiram carreiras de pesquisa científica, cinco reconhecem sua participação na feira como um impulsionador decisivo de suas vocações.

A design feature of the construction of electric heaters for non-pressurized spacecraft using a heating element in the form of a tape of a material with high resistivity, located on a flat base (electrical insulating substrate) in the form of a snake with the organization of the necessary gaps between the tapes, is revealed. A mathematical model has been developed for calculating the main design parameters of electric heaters: power, mass, heated surface area. The nomenclature of efficiency indicators used as optimization criteria has been formed: power utilization factor, filling factor of an electrically insulating substrate tape, surface density, energy-mass efficiency, thermal efficiency of heating, target efficiency. The methodological principles for ranking the requirements for the parameters of electric heaters are determined using the selected optimization criteria: the preferred use of tape materials with high resistivity and minimum thickness. A method is formulated for step-by-step calculation of the parameters of electric heaters in the presence of restrictions on the maximum heat flux density determined from the conditions for the use of electric heaters. General recommendations have been developed for choosing the parameters of electric heaters: use increased voltage, minimize the thickness of the heating element tape and the width of the gap between the tapes, determine the minimum value of the tape length for the maximum heat flux density at a given voltage rating.

A shaping structure is element in most transformable reflectors to ensure the required accuracy of the reflective surface. An umbrella reflector shaping structure is a system of tensioned dimensionally stable cords in the open position. External factors influence the cords of the shaping structure, which lead to a change in the length of the cords throughout the entire life cycle of the product. It is advisable to assess the stability of the geometric dimensions of the cords, from the point of view of labor intensity, on a piece of the shaping structure – the arch system. To conduct this kind of research, there is a need to develop special technological equipment. The article considers the requirements for technological equipment and testing. The authors propose an original design of technological equipment, which allows fixing the cords of the arch system with boundary conditions similar to a real reflector. The paper describes a 3D model of the technological equipment, on the basis of which a prototype was made. The prototype ensured the assembly of a separate arch system corresponding to the standard design in terms of size, configuration and cord tension. Tests were carried out to assess the measurement error of the arch system in the manufactured experimental model. The test results confirmed the possibility of using the developed technological equipment for component tests of the shaping structure.

The main methods for the determination of the object position using code phase and signal carrier phase measurements are given. An accuracy of pseudorange measurements of both carrier phase and group delay code signal depends on local phase center variations for the signals coming from different directions. The relation of group delay and local phase center of the antenna is determined wherein the key factor is frequency dependence of phase or local phase center variation in solid angle of the radiation pattern. The definition of local phase center whose coordinates depends on the direction of radio signal is given. The single helical antenna analysis of local phase center position is carried out considering that the radio technical performances of the navigation antenna’s spacecraft «Glonass» depends on the same ones of its radiating elements. The features and the technique for hodographs computation of the helical radiator’s navigation phased antenna array using electrodynamic simulation tools are considered. The offset estimation of local phase center is obtained. The features of that offset in relation to the radiator construction depending on the operating frequency are detected.
