Mechanics and Mathematical Modeling of Class III Treatment with Orthodontic Appliances with a Movable Ramp

Treatment of class III is a current problem in orthodontics that requires constant improvement of its methods, development of new or modifications of known methods and techniques. We have developed and studied the modification of removable functionally-directing orthodontic appliances for treatment of Class III, which consists of a plastic base, vestibular arc, retaining clasps, ramp, which is connected with the base by means of two torsion springs. Its usage ensures a prolonged contact of ramp with the teeth. We studied two types of club-shaped springs (torsion springs): one spring, which create an amortization effect during the action of the ramp, but do not change its inclination angle and second one – spring that seek to increase the angle of the ramp inclination due to the disclosure of its curl

A Creative Approach to Preparing Inclusive Music Lessons: The Role of Neuropedagogy in Inclusive Music Education

The article discusses the issue of music education for children with special needs in children’s art schools. It highlights the most relevant problem, namely, insufficient knowledge among music school teachers and art school teachers about the peculiarities of development and learning of such children. Besides, a significant gap in today’s music education is the lack of appropriate methods and techniques of music instruction that are suitable for learners with special educational needs. The article shows the most common disorders that allow for education in children’s music schools, reveals the difficulties encountered in teaching children with developmental delays and provides corresponding recommendations. The authors of this article believe that principles widely applied in corrective pedagogy can contribute to music education in children’s art schools. These principles include minimization, accessibility, cyclicity, intensification and comprehensiveness. When adapted to music pedagogy, they can be successfully incorporated into the educational process. Also, the article defines the category of children with special needs and describes a creative approach to preparing inclusive music lessons. Finally, it characterizes inclusion in music for children with developmental delays in mental and language abilities and identifies the role of neuropedagogy in inclusive music education.</p

Developing the Competency of Future Physical Education Specialists in Professional Interaction in the Field of Social Communications

The optimal combination of professional and personal qualities is extremely significant for professional activities of physical education specialists, who can engage in professional interaction in the field of social communications. The study aims to theoretically justify pedagogical conditions and experimentally verify the model of developing the competency of future physical education specialists in professional interaction in the field of social communications. At the formative stage, the following pedagogical conditions have been implemented: providing higher professional education of future physical education specialists with relevant information support; implementing an optimal combination of traditional and innovative modes of teaching, which assist the student in adapting to real-life conditions. The control group included in 36 individuals and the experimental namely, the questionnaire, titled “Clarifying Motivation to Achieve the Goal and the Striving for a High Social Status; the tests compiled by the author; the test, titled “Managerial Duties and Employee Relations”; a test for determining the ability to work in the system “man – man” and the test “Evaluating Organization and Communication Skills”. After the pedagogical experiment, 15.28% of CG students and 22.92% of EG students were at a high level of competency in professional interaction in the field of social communications. The results of the pedagogical experiment prove the effectiveness of the determined pedagogical conditions and the suggested model for developing the competency of future physical education specialists in professional interaction in the field of social communications

Ti-modifikovaný jílový kompozit pro odstranění vysoce toxických sloučenin chrómu ze znečištěné vody pomocí adsorpce

In the current work, 12 different Ti-modified clay composites were synthesised. XRD analysis and surface area measurements have been used to investigate the samples. The influence of the synthesis approach and adsorption experiment parameters on the final adsorption values of dangerous carcinogen Cr (VI) were investigated in concentration range from 2 mg/L to 42 mg/L with pH 4 and 6. In the result of the work the efficiency of carcinogen hexavalent chromium removing can be up to 98,5 % depending on the conditions.V současné práci bylo syntetizováno 12 různých Ti-modifikovaných jílových kompozitů. Pro vyšetřování vzorků byly použity RDX analýza a stanovení měrného povrchu. Byly zkoumány parametry adsorpčního experimentu na konečné hodnoty adsorpce nebezpečného karcinogenu Cr(VI) v koncentračním rozmezí od 2 mg/l do 42 mg/l s pH 4 a 6. Ve výsledcích práce bylo zjištěno, že účinnost odstranění karcinogenního šestimocného chromu může být až 98,5% v závislosti na podmínkách
