THE PECULIARITIES OF CALCIUM-PHOSPHORUS METABOLISM IN YOUNG CHILDREN
The issue of dental caries prevention has been discussed for many years; certain progress has been made in this area.
An important element in this respect is adherence to the basic rules of medicine «Non nocere» (do no harm).
Therefore, administration of any preventive medication should be strictly differentiated.
Of particular concern are young children with diseases of hard dental tissue against a background of somatic pathology, for example, genetically caused connective-tissue disease. Connective-tissue dysplasia is a developmental disorder of the connective tissue in embryonic and postnatal periods as a result of genetically modified fibrillogenesis in the extracellular matrix, leading to homeostasis disorders at the tissue, organ, and organism levels in the form of a variety of morphological and functional defects of visceral and locomotive organs with a progressive course.
Endogenous prevention allows subsequently a higher level of resistance to tooth decay. The use of calcium and phosphorus in the framework of the caries prevention programs is recognized as one of the most effective ways to prevent this disease.
In this regard, the aim of our study was to investigate calcium-phosphorus metabolism against a background of connective-tissue dysplasia in early-age children.
Materials and Methods. The study involved 39 children (the main group) aged from 1 year 2 months to 3 years with multiple caries and complicated forms of caries against a background of genetically caused connective-tissue disorder followed up at Dentistry Department of KhNMU.
All children were divided into four groups according to the age. Group 1 consisted of 7 children aged 14-18 months; group 2 - 8 children aged 19-23 months; group 3 - 7 children aged 24-29 months, group 4 -. 17 children aged 30-36 months. Consequently, the largest group (17 persons) included the children aged 30-36 months.
The children underwent biochemical tests of blood and urine for calcium and phosphorus content and excretion.
Our research revealed that the levels of calcium and phosphorus in the blood of the children in all age groups were within the physiological norm.
Calcium and phosphorus excretion with the urine in children of the main group was decreased (normal Ca excretion is 0.5-3.8 mmol/day, P – 1.0-25.0 mmol/day), thus at the age of 14-18 months Ca concentration was reduced by 0.1 mmol /day, P - 0.1 mmol/d., at the age of 19-23 months Ca concentration decreased by 0.15 mmol/day, P - 0.11 mmol/day, in children aged 24-30 months Ca concentration reduced by 0.1 mmol day, P -
0.18 mmol/day, in children aged 30-36 months Ca concentration decreased by 0.17 mmol/day, P - 0.17 mmol/day.
Conclusions.
1. When endogenous prevention is performed in early-age children with genetically caused connective tissue disorders, it is necessary to take into account the level of calcium and phosphorus excretion with the urine.
2. When genetically determined diseases of the connective tissue and the findings of blood and urine tests are present, the nutrition of the child should be corrected, i.e. meat broths, meat products, products from highgrade flour, semolina, milk products with a high fat content should be excluded
Approaches to the notion of a play in contemporary foreign psychology
The article introduces the definitions of a play and approaches to its understanding. On the basis of data obtained in several foreign studies the different criteria of play and such approaches to it as cognitive, narrative and socio-evolutionary are examined. The article provides the special analysis of terminological and contentual difficulties in search of play criteria and definition
The Importance of Taking Risks: A Report on the Conference
The paper gives an overview of the 14th interdisciplinary conference The Importance of Taking Risks held by the Welsh branch of the International Play Association. The meeting focused on various aspects of supporting children’s play and on the role of risk in child development. The conference had a clear multidis- ciplinary character and brought together specialists from a variety of fields: psychologists, teachers, social workers, experts in risk assessment, and health care professionals. The paper outlines how risk is understood in modern western theory and practice and distinguishes between risk and danger. A child must be taught to assess situations as safe or dangerous. However, modern developmental environment tends to reduce the possibility of risks for the child, which deprives him/her of the natural means of learning about the world and reduces creativity and independence and holds back the child’s self-regulation, prolonging compelled dependence and making children more infantile. The conference also involved discussions concerning tech- niques for risk assessment and a number of prevention programmes and practices. This work was supported by the Russian Foundation for Humanities (project No 15-06-10627 “Psychological and pedagogical analysis of children’s play environment of the modern city”)
The Children’s Playground in the Context of Cultural-Historical Psychology
The article describes the possible application of the principles of cultural-historical approach and activity theory to the inspection of toys and play environments. A children’s playground is treated as cultural means or artifact created by adults for starting a child’s activity. In terms of cultural and historical psychology, psycho-pedagogical analysis of a playground is based on the identification of the play value level and the compliance with the objectives peculiar to the age. Analysis and design are based on the understanding of the playground as a single space, where each element has the potential for any children’s development activity — games, communication, experimentation, etc. The following criteria of psychological and pedagogical inspection are identified and well-grounded: the principle of orientation to age-related peculiarities, the principle of high play value, the principle of transparency of objects, the principle of supporting acceptable risk, the principle of taking account of visitors’ activity levels, invitation to dialogue — the principle of dialogueness. The use of these principles in the course of designing playgrounds is illustrated by examples. These show that the conceptual apparatus of cultural and historical psychology may be used not only to explain the mechanisms and forms of mental development, but also for the analysis of particular conditions of a child’s mental development and design of play environments

Magic in healing practice: A case study in Vietnam and its philosophical assessment
The use of magic and religion in healing practices in Vietnam is relatively popular. In the folklore and folk religion of Vietnam, it is often said that “In case of sickness, follow any feasible cures [co benh thi vai tu phuong]” in the sense that all means, including using religious beliefs and rituals, will be used to get healing for oneself or one’s relatives. When people or their relatives get sick, besides going to medical facilities, they will look for a shaman, necromancer, monks, even priests, bishops, and pastors to cure the illness they or their relatives are suffering from. Based on Mircea Eliade’s theory published in The Sacred and the Profane (Eliade, 2016), the article has the ambition to offer a different perspective on the use of magic (sometimes considered as a religious ritual by the subject) to cure disease. We employ both the comparative and analytical methods of study as we explore concrete cases of treatment of patients with different religious beliefs (Ms. T’s case of treatment, following Buddhist practices in comparison with the healing cases of the Mother Goddess Worship and the Catholic Church). The authors propose that a uniquely Vietnamese philosophy of life (Life-philosophy) serves as a constitutive basis for the adaptation of magic in healing practices, being itself formed and influenced by these practices. © 2021, Slovenska Vzdelavacia Obstaravacia.

The Influence of BYOD Concept on Development of Learning Process in Universities
Education is one of the largest markets promoting implementation of Bring Your Own Device BYOD. The BYOD model was originated in colleges and universities, being stimulated by technologically advanced students, who demanded it, and administrators of educational entities, who agreed that allowance to get access to the network using personal devices was a competitive advantage. Nowadays this concept attracts great attention. People depend on their personal devices and want to have the opportunity to use them anywhere in order to make their life simpler and more efficient. While BYOD implementation increases, teachers determine new methods of integration of mobile devices into learning. The use of personal mobile devices of students for learning seems to be attractive for universities, since these devices would help to reduce expenses and to support teaching and learning. The research objective: to detect the level of influence of BYOD concept on learning process. In the conclsuoins authors confirm that BYOD is the dominant model in universities
