REFLECTION OF LABOR MARKET INTERESTS AND EXPECTATIONS IN EDUCATIONAL ORDER FOR CONTEMPORARY SCHOOL

Purpose of the study: The main objective of the study was the analysis of key labor market request content for the secondary education system, the level of employers' expectations compliance and actual learning outcomes, the research of resources and partnership interaction limitations of all interesting subjects in the process of an educational order development. Methodology: The main method was the questionnaire survey of experts (individual entrepreneurs, the heads of industrial and structural divisions) of Moscow (N = 316). The results of the expert survey showed the interest of employers in close cooperation with school in order to reflect the interests of the labor market in the educational order adequately. Results: The most motivated group is a small business, the leaders of the lowest level in the sphere of trade and service, who directly interact with the school graduates in the process of their early start of labor activity. The experts noted the problems in the development of the social competencies among schoolchildren: excessive self-esteem, an excessive level of claims, low level of willingness to work in a team, the lack of such qualities as responsiveness and responsibility. The cooperation between school and employers is limited to traditional sponsorship practices. The interaction of employers and educational institutions is quite fragmentary, it depends on a variety of random factors (personal and situational motives), which does not ensure the stability and the effectiveness of social partnership. Applications of this study: This research can be used for the universities, teachers, and students. Novelty/Originality of this study: In this research, the model of Reflection of Labor Market Interests and Expectations in Educational Order for Contemporary School is presented in a comprehensive and complete manner

Prediction of outcomes of cytomegalovirus infection of the initial few months of life

The research was based on the data of 155 newborns with manifestations of cytomegalovirus infection (CMV) appeared in the initial few months of life and on the results of the 7-years follow-up of this group of patients. While studying the courses and outcomes of CMV appeared in the initial few months of life in 155 patients of the tender age the disability is set for 22 (14,2 %) children. On the basis of discriminant analysis with the use of the most significant factors the model of prognosis of the outcomes of the carried infection was created in severe residual-organic disorders, dictating the necessity of determination of disability for children. This model can predict development of severe organ pathology in children of tender age after citomegalovirus infection appeared in the initial few months that will allow to select patients with high probability of disability and to realize for them individual rehabilitation measures to save their health in proper time

Журнальный клуб на английском языке в медицинском университете как перспективный инструмент обучения

Introduction. Despite widespread implementation of journal club in medical universities around the world, this activity is lacking in Russia. Currently, there are no publications about the evaluation of journal club at the Russian medical education system as an learning tool and its efficacy.The objective of this work was to describe the experience of participation in the journal club in order to assess participant’s satisfaction and preliminary efficacy of the meetings as well as to identify opportunities to improve and implement journal club rounds.Methods and materials.

Factors to affect inbred beet plants while developing material for linear selection

Considering its capacities, the generative system of Beta vulgaris L. is regarded as highly productive. While inbreeding, the reproductive potential of cross-pollinated beet plants with gametophytic self-incompatibility (SI) changes significantly and is determined by a joint effect of multiple factors including the level of inbred depression. In the present study, original data have been obtained revealing relationships between inbred beet seed productivity, its self-incompatibility and microgametophyte parameters, which is crucial for developing and maintaining constant fertile beet lines. It has been discovered that inbred depression increases the number of sterile microgametes and anomalous pollen grains, reduces pollen fertility and the length of pollen tubes. As a result, the seed yield in inbred beet progeny, including SI ones, reduces significantly just after the third inbreeding. At the same time, highly productive inbred beet is characterized by a lower rate of pollen tube growth in vitro. In inbred plants, there is no close relationship between pollen viability and seed productivity, because the elimination of germinated male gametes and degeneration of seed embryos may go over the entire period of fertilization starting its progamic phase. The SI plants have more degenerating embryos than self-fertile ones, but seed vessel outgrowth in the seeds with abortive embryos makes them morphologically similar to fertile seeds. For that reason, when assessing inbred beet plants based on their self-incompatibility/self-fertility, one should consider the qualitative characteristics of the seeds. Using the method of recurrent selection based on such factors as seed productivity, pollen tube length and field germination rate increase the output of plant forms with a potentially high self-compatibility in their progeny. To support such genotypes in the progeny, one has to, starting from the third inbreeding, perform sib crossing to reduce the negative effect of inbred depression and self-incompatibility

СОЗДАНИЕ СЕЛЕКЦИОННО ЦЕННЫХ БИОТИПОВ СВЁКЛЫ СТОЛОВОЙ С ИСПОЛЬЗОВАНИЕМ КУЛЬТУРЫ ШТЕКЛИНГОВ

The long period of time needed for production of homozygous ms-and mf-lines in biennial crop is a problem in development of heterotic hybrids in red beet. The use of steckling culture and protected cultivation technology are the  suitable methods  to  speed  up  the  development  of breeding lines. However, the relationship between exhibition of CMS trait in seed plants and horticulturally valuable traits of steckling is very important aim of the study to be considered. The study was performed in 2012-2014. The red  beet  inbreeding  lines (I2-I5), obtained  through steckling culture in low-volume technology under protected cultivation condition were used as a plant material for the study. The generations that were obtained were from cultivar population ‘Nezhnost’ and a hybrid population of foreign origin. As a result, it was shown that one of criterions of indirect selection of ms-form in inbreeding generation may be the fast-maturity of stecklings that determined their yield weight at harvesting. The average weight of steckling belonging to sterile plants in progenies of different inbreeding generations, not depending on the time of harvesting was higher than in fertile plants. Therefore, probability to select the valuable ms-forms among groups of fast-maturing  plants with  greater weight  of steckling was higher. The selection of stecklings from smaller size groups of middle maturing and late maturing inbreeding progenies is required to  develop valuable mf-lines with high ability for fertility maintaining.Проблемой при создании гетерозисных гибридов свеклы столовой как двулетней овощной культуры, является длительность получения гомозиготных ms- и mf-линий.   Для ускорения создания линейного материала  перспективно использование культуры штеклингов и защищенного грунта.  Однако  при  использовании  данного способа  важен характер взаимосвязи между проявлением признака ЦМС семенных растений и селекционно значимыми признаками штеклингов,  что и явилось целью данных исследований. Исследования  проводили  в  2012-2014  годах. Материал для исследований  – инбредные потомства  (I2-I5)  свёклы столовой, полученные  через  культуру штеклингов, с использованием малообъемной технологии  в  защищенном грунте. Потомства получены на основе сортопопуляции Нежность и гибридных популяций иностранного происхождения. В результате исследований установлено, что одним  из  критериев косвенного  отбора ms-форм  в инбредных  потомствах  может являться скороспелость штеклингов, которая определяет их массу к моменту уборки.  Средняя  масса  штеклингов  стерильных  растений в потомствах разных поколений инбридинга больше, чем у фертильных, не зависимо от срока уборки. Поэтому, вероятность отбора ценных ms-форм выше в группе скороспелых растений с большей массой штеклинга. Для создания перспективных  mf-линий  с высокой  закрепляющей способностью,  наоборот, целесообразно вести отбор штеклингов в более мелкой фракции среди среднеспелых и позднеспелых инбредных потомств

New V-shaped 2,4-di(hetero)arylpyrimidine push-pull systems: Synthesis, solvatochromism and sensitivity towards nitroaromatic compounds

Novel D–π–A–π–D type pyrimidine-based dyes, possessing (hetero)aryl electron-donating groups in 2,4-positions were synthesized, and their photophysical properties were investigated by using absorption and emission spectral analyses. All dyes proved to exhibit a strong emission solvatochromism with quantum yields up to 0.96, depending on their molecular structure and solvent polarity. The compounds have been established to undergo a reversible protonation, directed at nitrogen atoms of the pyrimidine ring, and these phenomena are associated with dramatic color changes. In addition, fluorophores 5a-d show a high sensitive response for nitroaromatic traces in solutions or real-time detection of their vapors in air. These findings indicate that the compounds obtained can be regarded as excellent fluorophores for fluorescent material applications. © 2018 Elsevier LtdRussian Foundation for Basic Research, RFBR: 17-03-00011-AMinistry of Education and Science of the Russian Federation, Minobrnauka: 4.6759.2017/BCThis work (synthetic part and sensory properties) was supported by the Russian Foundation for Basic Research (Research Project No. 17-03-00011-A ).
