Pedagogical potential of the artistic-design activity within the context of development of the graphic skills in adolescents

© Medwell Journals, 2015. Today the design activity holds a high position in the educational process of the modern schools as it forms the students' need and readiness for independent acquisition of the new knowledge, develops their personal qualities, teaches how to implement the own ideas in physical or esthetical form. Along with that in the course of review of the research literature (Emelyanova, Eremeyeva and Kalashnikova), we have found out that this kind of activity in the artistic education has been under investigated. Therefore, we referred to the concept of the artistic-design activity nature and determination of its pedagogical potential influencing the simultaneous, integrated activation of such components of the graphical skills development in adolescents as cognitive, practical, motivational, perceptive, emotional-sensual one. The following methods have been used in the research: review of the pedagogical, psychological, art science literature, analysis of the educational, program and regulatory documentation; observation, surveying, testing, interviewing, method of expert assessment, pedagogical experiment, generalization and systematization of empirical material, interpretation of data obtained. The result is that this study reveals the peculiarities of the artistic-design activity, its high pedagogical potential represented by the unity of the educational, developing and motivation functions has been determined and experimentally proven which promotes to the efficient and integrated development of graphical skills in adolescents. Practical relevance of the research consists in the fact that the results obtained may be accounted for and used by development of the adapted and proprietary educational programs by the arts and design teachers at general education schools and institutions for additional education providing specialized artistic training

Antibacterial effect of nisin in vitro

Results of experimental studies of antimicrobial action of gel compositions containing active substance nisin are presented in the article. It is shown that increasing concentration of nisin at constant concentrations of the other components in the mixture inhibits growth of Staphylococcus aureus and Pseudomonas aeruginosa. The optimal concentration of nisin at which the process of pathogens growth inhibition is the most effective was determined in the experiment

Investigation of physico-chemical characteristics of carboxymethylcellulose colloidal carriers for medical preparations

Introduction. Physico-chemical peculiarities of processes of preparation and aging of colloidal carriers (gels) based on carboxymethylcellulose (CMC) for medical preparations which are planned to be used as a treatment for burn wounds are considered in the article. Studies were conducted in the Central Scientific Research Laboratory of theKharkivNationalMedicalUniversity in 2019.The objectives of the study. The objective was to study the applicability of CMC solutions and their modified analogues for the gel-based pharmaceutical preparations.Material and methods. Experimental studies were carried out under laboratory conditions using equipment for viscosity and pH measuring.Results. The influence of concentration, temperature, and acidity on viscosity of gels was investigated. The gels were tested on aging during storage. The stability of these solutions and syneresis process were investigated. The influence of added modifiers – glycerol and ascorbic acid on the consistency, acidity, susceptibility to contamination and term of storage of the gels was determined.Conclusions. It is shown that unmodified solutions have the highest viscosity and the greatest stability. Increasing of temperature reduces duration of dissolution of CMC and viscosity of the gels. Modification by ascorbic acid significantly reduces viscosity and pH of gels, while addition of glycerol does not affect the stability but increases susceptibility of these solutions to contamination. Storage of obtained solutions for three months under normal conditions at room temperature leads to syneresis and total loss of initial consistency. The gels modified by ascorbic acid are shown to be the least stable. Graphic dependences of these processes are obtained and functions are calculated on the basis of experimental research with the use of mathematical modeling methods. The obtained models will allow to predict physical and chemical properties of gels in order to define the necessary parameters of preparation at the stage of development

The Influence of Meteorological Parameters and Other Factors on Soil Radon Dynamics

The paper presents the results of the research in the degree of the effect of space weather meteorological parameters and factors on the dynamics of soil radon levels and [alpha]- and [beta]-radiation flux densities in a seismically passive region. The cross-correlation analysis showed a significant correlation of [beta]-radiation flux density with temperature in summer, and no correlation in winter. A significant relation between [alpha]- and [beta]-radiation flux densities and pressure within the intra-annual range was not observed. The investigation of the high-intensity precipitation effect on radon volumetric activity and [alpha]- and [beta]-radiation flux densities showed their abnormal increase. The dependence of the anomaly duration on the depth was revealed. The abnormal jumps in [alpha]- and [beta]-radiation flux densities data series occur in the snow-melting periods as well. Low-intensity precipitations significantly violate the standard "diurnal variations" of [alpha]- and [beta]-radiation soil fluxes and radon volumetric activity. Fourier analysis showed the diurnal (24 hours) and semidiurnal (12 hours) harmonics for the observed radiation values at a depth of 0.5 m. The obtained results can be used for interpretation of the data on the soil radon monitoring in order to predict earthquakes, etc

Discussion questions about the role of a lecture in the process of teaching the discipline "Propaedeutics of pediatrics" in the context of modern medical education

Важливою задачею сучасної вищої школи України є всебічне вдосконалення навчального процесу на основі кращих досягнень світової та вітчизняної дидактики. Серед великого переліку форм і методів навчання у закладі вищої освіти лекція завжди посідала чільне місце. Проте на сьогоднішній день в умовах реформування вищої освіти питання про доцільність лекції, як невід’ємної частини навчального процесу, активно дискутується. Метою дослідження було визначення значимості і роль лекції в процесі викладання дисципліни «Пропедевтика педіатрії» в умовах сучасної медичної освіти. Проведено анонімне анкетування 593 студентів третього курсу Дніпропетровської медичної академії, серед яких: 377 респондентів – вітчизняні студенти, 170 – іноземні англомовні студенти та 46 – іноземні російськомовні студенти. Як показали результати, для більшості вітчизняних та іноземних студентів третього курсу лекція є обов’язковою формою навчання, а лекції з «Пропедевтики педіатрії» є досить інформативними та необхідними. Крім того, студенти досить високо оцінили роботу професорсько-викладацького колективу з розробки лекцій та рівень подачі лекційного матеріалу на кафедрі пропедевтики дитячих хвороб. Найчастішими пропозиціями як вітчизняних, так й іноземних студентів, щодо підвищення ефективності лекцій виявилися: збільшити кількості лекцій та навчальної інформації в них; наводити більшу кількість клінічних прикладів з власного досвіду практичного лікаря; збільшити кількість відеоматеріалів під час лекційного заняття. Отже, лекція в сучасних умовах вітчизняної вищої медичної освіти повинна залишатися провідною та необхідною формою організації навчального процесу. Для підвищення ефективності лекційного матеріалу викладачам необхідно враховувати індивідуальні особливості та потреби студентів
