ATTITUDES OF PRE-SERVICE TEACHERS IN PRIMARY AND PRE-SCHOOL PEDAGOGY TO WORK IN THEIR SPECIAL SUBJECT
No full textThe purpose of the study was to examine the attitudes of pre-service teachers in primary and pre-school pedagogy to work in their subject. 76 pre-service teachers in primary and pre-school pedagogy on the Bachelor’s degree from Trakia University in Stara Zagora participated in the research. Half of the respondents had professional experience at primary schools or kindergartens. A special questionnaire was applied, related to the attitudes of the future teachers. The statistical method used for the research was alternative analysis.
Factors influencing the professional realization and career development of the future teachers in the conditions of the dynamically reforming education in Bulgaria were presented. The pre-service teachers in primary and pre-school pedagogy were willing to continue their qualification and education. The future teachers would like to work in their special subject and would not change the profession. Different motives for professional realization of future teachers were established
USAGE OF 3D TECHNOLOGIES IN STEREOMETRY TRAINING
No full textStereoMV is a part of а dissertation on a topic "Stereoscopic Training System". The main purpose of the stereo system is to facilitate learning of the concepts of stereometry. The system is the author’s and offers a new approach for generating geometric bodies. The boundary method is used for creating the figures, which is based on the method of the boundaries of Isaac Newton and the "Indivisible" of the Italian mathematician Bonaventura Cavalieri. The study shows how by using 3D technologies such as virtual reality and 3D printing, the process of teaching in stereometry classes will be significantly facilitated. The report presents a comparative analysis of the existing and new way of creating a regular polygon. The graphics can be presented in two ways, namely: solid and transparent. The stereo system provides an opportunity for converting from solid to transparent. The 3D model depends on its geometry and appearance. Geometry means mathematical description and the appearance is defined by the: material, texture, light and transparency. After creating the stereometric figure, the system enables it to be converted to .obj file (mesh)
THE COMPARISON OF PIRLS, TIMSS, AND PISA EDUCATIONAL RESULTS IN MEMBER STATES OF THE EUROPEAN UNION
No full textThe PIRLS (Progress in International Reading Literacy Study), TIMSS (Trends in International Mathematics and Science Study), and PISA (Programme for International Student Assessment) have become gold standards for the international comparison of children’s performances, when aged 10 and 15 years.
This paper focuses on secondary analysis of basic statistical indicators on reading literacy (PIRLS), as well as the mathematics and scientific literacy (TIMSS) of pupils at 10 years of age, followed by their reading, mathematics and scientific literacy at 15 years of age (PISA). It compares the pupils’ main educational results in PIRLS and TIMSS with their PSA results. PIRLS, TIMSS, and PISA help to identify key problems within pupils’ educational levels in these selected literacies and create effective educational policy measures.
One aspect of the comparison within the research paper is the aggregate indicator; this is the arithmetic mean of PIRLS and TIMSS results, using pupils’ PIRLS results from 2001, 2006, 2011 and 2016, and TIMSS results from 2007, 2011 and 2015. The other aspect of the comparison is the aggregate indicator; which is the arithmetic mean of pupils’ PISA results for 2006, 2009, 2012 and 2015. A significant relationship was found to exist between the arithmetic mean of pupils’ PIRLS, TIMSS, and PISA results.
Political and professional policy decisions within schooling affect the early years of pupils’ school attendance. This has a significant impact on their future education at all levels of schooling. The findings of this paper support a hypothesis regarding the effects of pupils’ educational performance and the need for measures to improve education in schools that should be adopted on an ongoing basis

DEGREE OF DIGITAL TECHNOLOGICAL INTEGRATION IN THE BULGARIAN SECONDARY TECHNOLOGICAL EDUCATION
No full textGlobal informatization is one of the dominant trends in contemporary social reality. Digital information and communication technologies have enormous innovation potential for the overall modernization and transformation of education and the enrichment of pedagogical sciences. Realizing this potential requires technologies to be fully integrated into educational practice. A high degree of integration is a prerequisite for the implementation of constructivism, increasing autonomy, personal responsibility of learners and the opportunity for personalized learning.
Digital technological integration is a progressive change of education to a degree of transformation. In the process of gradual merging of information and communication and pedagogical technologies, innovative pedagogical practices are created, and they cannot be realized without modern technological means. The characteristics of the methods of teaching and learning with digital technologies determine different degrees of integration which are entry, adoption, adaptation, infusion, and transformation.
The current features of the applied methods for using Information Communication Technology (ICT) in the Bulgarian secondary education in technology, and entrepreneurship (grades 5-7) were studied by surveying 127 pedagogues teaching this subject. A questionnaire is attached examining the goals, frequency use of digital tools in the educational process, and the applied management decisions for choosing the digital tools and working with them. The analysis of the obtained data showed that ICT was used, but the degree of integration was low and corresponded to the initial levels of entry and initial adoption of the integration process. In isolated cases, lessons were held according to how students performed in activities specific to their level of adaptation
LABORATORY DIAGNOSTIC CRITERIA OF RENAL IMPAIRMENT IN PREMATURE NEWBORNS WITH SEVERE PERINATAL PATHOLOGY
No full textIntroduction: Critically ill neonates are at high risk of developing renal impairment (RI), including acute kidney injury (AKI), which is associated with short- and long-term pathological outcomes and increased mortality. The incidence of acute kidney injury varied by gestational age (GA) group.
Aim: Identify laboratory diagnostic criteria of RI in premature newborns (PNs) with different GA who had severe heterogeneous perinatal pathology.
Methods: The study was a prospective cohort of patients admitted electively to the III level Neonatal Intensive Care Unit at the Clinical Maternity Hospital 2 (Chernivtsi, Ukraine) between December 2015 and January 2018. One hundred sixty three PNs were treated at the hospital, from which a total of 68 patients were recruited into the study. Inclusion criteria: the GA is more than 24 weeks and less than 37 weeks; birth body weight is more than 500 g and less than 2500 g; presence of clinical signs of severe perinatal pathology. The severity of the perinatal pathology was classified on the basis of the neonatal Therapeutic Intervention Scoring System. The PNs were divided into three groups according to the GA: Group I consisted of 25 newborns born at the GA of 24-31 weeks, Group II – 25 newborns born at the GA 32-33 weeks, Group III – 18 newborns were born in a GA of 34-36 weeks.
The levels of sodium, potassium, calcium and chlorine, alanine aminopeptidase, and aspartate aminopeptidase were measured in serum. The levels of creatinine and urea were measured in serum and urine. The concentration of total protein, albumin, α1-microglobulin, and β2-microglobulin was measured in urine.
Findings and results: All PNs had signs of severe perinatal pathology and a neonatal Therapeutic Intervention Scoring System score of 10 or higher during the early neonatal period. There was no statistically significant difference in most serum biochemical parameters between groups of the study, excluding the level of serum chlorine. Our results demonstrated no significant difference in levels of urinary total protein and albumin between groups of the study, but showed a progressive increase the level of urinary creatinine and urea with increasing GA. The maximum level of urinary β2-microglobulin was found in “Late-Preterm” newborns who were born at 34-36 weeks, the minimal level of urinary α1-microglobulin was detected in patients with GA 32-33 weeks.
Conclusions: Our results demonstrated that most PNs with severe perinatal pathology have some aspects of impaired tubular and glomerular functions. This is evidenced by changes in urinary new biomarkers. We found direct correlations between GA and serum creatinine (r=0.31, p<0.05), urinary creatinine (r=0.40, p<0.05), urinary α1-microglobulin (r=0.37, p<0.05), and urinary β2-microglobulin (r=0.51, p<0.05). Longer longitudinal cohort studies on PNs are required to determine the prognostic and diagnostic criteria of RI in these patients
INVESTIGATION OF EXTERNAL RESPIRATORY FUNCTION AND HEMOSTASIS SYSTEM’S STATUS IN PATIENTS WITH CHRONIC OBSTRUCTIVE LUNG DISEASE WITH CONCOMITANT CHRONIC PANCREATITIS
No full textINTRODUCTION: It can be assumed that the comorbidity course of сhronic obstructive pulmonary disease (COPD) and chronic pancreatitis (CP) can enhance the clinical symptoms of both diseases and lead to frequent relapses of the pathological process due to changes in the proteolysis intensity of high and low molecular weight plasma proteins and the state of the hemocoagulation.
OBJECTIVE: To establish the features of hemocoagulation and proteolytic hemostasis at COPD with concomitant CP.
METHODS: 120 patients with COPD and CP were examined. The function of external respiration, total coagulation potential of blood plasma, the state of enzymatic and non-enzymatic fibrinolysis, total fibrinolytic activity were investigated.
RESULTS: CP contributes to the development of broncho-obstructive syndrome, and the maximum indicators of reduction of FEV1 relative to the proper values are observed in patients with a comorbid course of COPD and CP. Reducing the intensity of collagenolysis in patients of groups 1-2 contributed to the development of diffuse pulmonary fibrosis in response to chronic inflammation. The imbalanced increase in the intensity of proteolysis due to reduced expression of its inhibitors in COPD patients with CP led to progressive destruction of the cell membranes of alveolocytes, acinar epithelium of pancreas and epithelium of the bronchial mucosa, acceleration of their apoptosis and development of desquamation, atrophic changes, metaplasia, and the like. The above factors are active as inducers of inflammation, and the formation of pulmonary fibrosis and fibrosis of the pancreas.
CONCLUSIONS: In COPD patients with accompanying CP are an increase in the lysis rate of low and high molecular weight proteins and a decrease in blood collagenolytic activity on the background of a significant imbalance in the activity of plasma proteinase inhibitors. Defined suppression of the activity of the anti-coagulation system factors and enzymatic, Hageman-factor-dependent fibrinolysis indicates the formation of hypercoagulation syndrome in these patients
NANOCHROMIUM CITRATE: ANTIHYPERGLYCEMIC AND PANCREATOPROTECTIVE ACTION AGAINST UNDERLYING DEXAMETHASONE-INDUCED DIABETES MELLITUS
No full textINTRODUCTION: The Ukrainian State Scientific-Research Institute of Nanobiotechnology and Resources Saving has received nanochromium citrate (NCC), a new chrome compound, by means of the electric pulse aquananotechnology method.
OBJECTIVES: to determine nanochromium citrate efficacy with experimental dexamethasone-induced diabetes through the results of antihyperglycemic activity and its effect on the pancreatic histological structure.
METHODS: diabetes mellitus was simulated by dexamethasone administration on 18-month male rats. The morphological structure of the pancreas was examined in comparison with metformin. Examination of the pancreas morphological structure considered the amount, distribution and size of the pancreatic islets and their cellular shape.
RESULTS: on the 14th day of simulated diabetes mellitus the preventitive -therapeutic indication of nanochromium citrate promoted a decrease of glycemia level twice. The administration of nanochromium citrate with underlying diabetes mellitus is not inferior to metformin and its protective effect on the pancreas morphological structure exceeds the effect of metformin.
CONCLUSION: nanochromium citrate of experimental dexamethasone-induced diabetes mellitus in rats decreases the glycemia level twice which does not differ reliably from the effect of metformin antihyperglycemic. The cytoprotective effect of nanochromium citrate produced on the histological structure of the pancreas is found to exceed metformin action
ACCUMULATION AND MOBILE FORMS OF SOME HEAVY METALS IN ROADSIDE URBAN SOILS
No full textThe accumulation of heavy metals and toxic elements in the topsoil horizon of urban areas is a big environmental problem as they could have long-term implications not only for the soils themselves but also on the human health and well-being. Many studies have shown that there is a clear relationship between the level of urbanization, volume of traffic, intensity of anthropogenic activities and heavy metal load.
We aimed to analyze the accumulation of heavy metals at urban roadside soils and to assess the proportion of their mobile forms. The total content and mobile forms of Cu, Mn, Pb and Zn in soils samples collected along the main boulevards of Plovdiv (Bulgaria) was determined by two instrumental methods - ICP-OES and ICP-MS.
The maximal concentrations were found in the Central and Eastern administrative regions of the city of Plovdiv. This finding well correlated with the wind rose characteristics and urban gradient theory. Our results revealed that the mobile forms of Mn represented 1.38-2.21% of total content and the mobile forms of Zn represented 8.48-11.81% of total content in studied urban soils. Mobile forms of Cu and Pb varied significantly and were in the range of 7.04-14.2% and 7.3-18.67% of the total content, respectively
