One of the challenges of modern education is to prepare young people for an informed choice of profession and successful implementation of professional activities in adulthood. Since digital skills and the acquisition of relevant competencies are key requirements of today, there is a need for pedagogical universities to train specialists capable of addressing the challenges of schoolchildren’s career self-determination, taking into account the school curriculum in mathematics, informatics, economics, and other fields. To address this challenge, it is necessary to utilize not only new career guidance technologies but also improved training programs for future teachers. The materials presented in the article were developed for the training of teaching staff at the Faculty of Mathematics of Perm State Humanitarian Pedagogical University as part of the implementation of the regional component of the curriculum, as well as for the continuing education of future teachers. The relevant professional tests were tested, in particular, during the implementation of the all-Russian project for early career guidance for schoolchildren “Ticket to the Future”, with state support as part of the national project “Education”. The study made it possible to identify new opportunities for implementing the paths of future professional self-determination for schoolchildren in the digital educational ecosystem and, on this basis, formulate recommendations for training math and informatics teachers, concerning both the content of specialized disciplines in the optional part of the curriculum and their teaching methods.

In the article, taking into account the challenges of the global information revolution, modern socio-educational realities, the authors substantiate the need for a communicative approach in teaching physics as one of the methodological approaches of a new scientific direction – psycho didactics of physics. The purpose of the article is defined as the coverage of some results of experimental teaching of physics to high school students of a secondary school based on a communicative approach with elements of bilingualism, its essence is characterized. Using a specific example, the author’s methodology for implementing this approach was first demonstrated, the need for its integration with other psycho-didactic approaches with the aim of comprehensive development of the student’s personality in the process of teaching physics is emphasized. Some experimental data are presented that make it possible, as a first approximation, to optimistically evaluate the results of testing the methodology of the communicative approach with elements of bilingualism in physics education, the prospect of further studies to obtain data on a more voluminous statistical sample is outlined , as well as to identify the possibility of using the proposed methodology in studying other disciplines in natural sciences in both secondary and high school.

The multilayer model of computer is its representation as a sequence of layers (levels): from physical encoding of the values 0 and 1 to application software. Each layer has a specific meaning for forming a complete picture of knowledge. In the article the traditionally distinguished layers of the model are compared with the content of the established at the school informatics course. It is shown that in the program of advanced course for grades 10–11 the material that is to one degree or another related to each of the layers can be found. however, in light of the urgent need for domestically produced computing equipment and its element base, the proportion of studying some layers should be increased. based on the analysis of the federal work programs for the school informatics course, specific recommendations are provided on possible improvement of the discipline content. the article will be useful for teachers, as well as for pupils interested in computers and wishing to connect with them future specialty.

Background. In the treatment of gastroesophageal reflux disease, patients are usually advised to make lifestyle changes and prescribe drugs from the proton pump inhibitor family, but drug-resistant gastroesophageal reflux disease is becoming an increasingly common problem. In addition to the growing resistance of gastroesophageal reflux disease to therapy with proton pump inhibitors, the safety of long-term therapy with drugs of this group has been increasingly discussed in recent years. In this regard, the question arises about finding safe alternative ways to get rid of clinical manifestations of the disease at uncomplicated stages of the course in patients with gastroesophageal reflux disease. Objective. Evaluation of the effectiveness of the use of the herbal preparation (biologically active supplement) Liv Lively in patients with non-erosive reflux disease. Materials and methods. 40 patients with non-erosive reflux disease were examined, who were tested before and 1 month after therapy with the herbal preparation using the RSI, GSRS (Russian version) and MOS SF-36 questionnaires. Results. In the examined patients, 1 month after treatment with the herbal preparation, there was a statistically significant decrease in the intensity of such esophageal and extraesophageal symptoms of the disease as hoarseness or voice change (р = 0.000057), coughing, perspiration, mucus formation or postnasal congestion, a feeling of the foreign body in the, as well as heartburn, burning sensation behind the sternum, in the esophagus, chest pain, digestive disorder (р = 0.000001). After treatment, there was a statistically significant decrease in the total score of the GSRS questionnaire, as well as in such indicators as abdominal pain, gastroesophageal reflux disease syndrome itself, as well as dyspeptic syndrome and constipation syndrome (р = 0.000001). In 1 month after the therapy, there was a statistically significant improvement in such indicators of the SF-36 questionnaire as the state of health in general and at the moment (p = 0.00001), improved tolerance to heavy physical exertion (р = 0.00001), as well as the general physical and emotional state, the indicator of physical pain and the tendency to feel susceptible to diseases (р = 0.000012).

We have summarized the results of xylotrophic agaricoid basidiomycetes long-term monitoring in some types of indigenous and derived forests in the southern taiga subzone of Perm Krai. We carried out the research by a stationary method on the test 50×20 m areas, one in each type of forest: spruce forest at the brook, sorrel spruce forest and birch forest. We did the work in three periods: I – 1975–1977, II – 1994–1996, III – 2010–2012. The collection of material was carried out annually: in August 3 times with an interval of 10 days (the species composition, number and air-dry biomass of basidiomes were taken into account), and in September once (only the species composition of fungi was taken into account). To date, we have established that the number of xylotrophic agaricoid fungi in the studied forest types varies from 60 (sorrel spruce forest) to 66 (birch forest). Most of the identified species belong to the Tricholomataceae family (37.7–43.3% of the total number of xylotrophic fungi species in each of the biogeocoenoses). There was an annual accumulation of detectable fungal species, with the largest number of species (67–75%) detected from 2 to 9 times, and 2–3% of them were permanent, occurring annually. There was relative stability of the species composition of higher vascular plants (Jaccard generality coefficient: J = 56–88) over time and more significant changes in the species composition of xylotrophic fungi (J = 36–50). The spruce forests had the most similarity of fungi species composition between the cenoses by periods (J = 44–52), and for the entire observation period, the sorrel spruce forest and birch forest had the maximum Jaccard index between cenoses (J = 56). The yield of xylotrophic agaricoid fungi in the studied cenoses varies by years of observation. The birch forest had the largest number and biomass of basidiomata for all the three periods of the research. A decrease in the number of basidiomes of xylotrophic fungi in the sorrel spruce forest was established with an increase in the average monthly air temperature in August (Spearman correlation coefficient: rs = −0.70). The sorrel spruce forest was the most favorable for the biota of xylotrophic agaricoid basidiomycetes, both in number (Shannon index: H = 1.23) and in biomass (H = 1.20), during all the research, since the biota of xylotrophes of the specified cenosis was more diverse and its components were most aligned.

BACKGROUND: This study examines the main aspects of the competence-based approach of dentists in the treatment of patients with increased tooth abrasion (ITA). ITA is a serious problem that can lead to oral diseases and tooth loss. The competence-based approach in the treatment of patients with ITA plays a key role in the prevention and treatment of this disease. A study examining the knowledge of dentists in providing care to patients with ITA will reveal the level of training of specialists in this field. This will allow us to assess the need for additional training and advanced training of dentists for the effective treatment of patients with ITA. The results of the study can be used to improve the work of dental institutions and educational programs for dentists. This will improve the quality of dental care, improve the prognosis of the disease in patients with ITA and reduce the risk of complications. AIM: To evaluate the knowledge of dentists of different specialties in providing care to patients with ITA. METHODS: The research is based on the results of a sociological survey conducted by questioning 175 dentists of different specialties. The survey was conducted according to the questionnaire developed by us «Assessment of professional competence in the tactics of managing patients with ITA by dentists of different profiles». The questionnaire included general information about the respondent (age, specialty), questions related to ITA (concept, complaints, symptoms, prevention, treatment), assessment of the questionnaire procedure. RESULTS: The study demonstrated a relatively low competence approach of dentists of various specialties in the prevention and treatment of patients with ITA. CONCLUSION: The study shows the lack of interaction between dentists in the treatment of ITA. The results of the study and the high prevalence of ITA have determined the need to develop clinical recommendations for the prevention and treatment of ITA.

Abstract One of the important areas in fluid mechanics is thermal convection; its study is an urgent task from the point of view of effective control of heat and mass transfer. With increasing energy consumption worldwide, improved energy transfer methods are required. Various complicating factors can either strengthen or weaken energy transport mechanisms. In the current work, attention is paid to the libration effect as one of the effective ways to control heat transfer in a rotating cavity. The experiments are aimed at a study of convective flows generated in a flat layer unevenly rotating around a horizontal axis. The flat boundaries are kept at different temperatures. It is found that the cavity librations noticeably intensify the heat transfer in a layer. The flow structure obtained using the PIV method for the cases of uniform and non-uniform rotation of the cavity is presented for the first time. The effectiveness of librations for the intensifying heat and mass transfer in a rotating hydrodynamic system is shown.
