TYPOLOGY OF DYSGRAPHIA ERRORS IN PERFORMING THE WRITING TASK 'PRODUCING YOUR OWN TEXT' BY BILINGUAL PRIMARY-SCHOOL STUDENTS
No full textThe article presents the results of a field logopedic study of third- and fourth-grade bilingual students and the research material created by them while carrying out a writing task of producing a text of their own. The aim of the experiment is to analyze the quantitative and qualitative parameters of the dysgraphia errors in bilingual students (ethnic Roma and Turks) at the text level and on this basis to identify their typology and dependence on some linguistic and social factors. For the purposes of the research, a toolkit has been developed that includes groups of methods for the study of the following: the psychosomatic and the academic status, the elementary graphic habits; the phonemic gnosis; writing in different situations; identification and typologization of typographical errors through a criterion system. The results clearly show that the prevailing errors made by the bilinguals are analytic-synthetic. Regarding the other types of errors, significant differences have not been registered. The analysis of the results showed significant differences in terms of gender, ethnicity/language status and type of settlement
ESTIMATION OF THE TIME SINCE DEATH BY USING THE POLARIZATION MULLER-MATRIX MICROSCOPY OF BIOLOGICAL TISSUE IN CASES OF ALCOHOL AND CARBON MONOXIDE POISONING
No full textIntroduction: This paper aims to investigate and substantiate the information capabilities of the objective method of azimuthal-invariant polarization Müller-matrix microscopy of histological sections of biological tissues (BT) in the diagnosis of time since death (TSD) in alcohol and monoxide poisoning.
Objectives: The purpose of the study was to evaluate the diagnostic capabilities of the azimuthal-invariant Muller-matrix polarimetry technique of the polycrystalline constituent of BT and human body fluids in determining the TSD in cases of alcohol and carbon monoxide poisoning.
Results: A comprehensive experimental study of the diagnostic efficiency of the azimuthal-invariant Muller-matrix polarimetric microscopy of the polycrystalline component of histological sections of the brain, myocardium, adrenal glands, liver, and polycrystalline blood films from dead persons for the diagnosis of TSD in cases of alcohol and carbon monoxide poisoning.A sensitivity range of 24 hours was determined using the method of the azimuthal-invariant Muller-matrix polarimetric microscopy of the polycrystalline component of histological sections of the myocardium for the diagnosis of TSD in cases of alcohol and carbon monoxide poisoning.
Conclusion: The results showed the effectiveness of the studied methodology and the prospect of further research in this direction
DIAGNOSTIC POSSIBILITIES OF ANALYSIS OF THE MAP OF LINEAR BIREFRINGENCE OF THE CRYSTAL FRACTION OF VITREOUS BODY FOR ACCURATE DETERMINATION OF THE TIME SINCE DEATH
No full textIntroduction: This paper discusses the possibility of polarization microscopic tomography of polycrystalline structure of vitreous body (VB) for use in forensics and in determining the time since death (TSD).
Objectives: The purpose of this study was to develop a new set of forensic criteria to enhance the functionality of the high-precision definition of TSD over a long period of time according to polarization microscopic tomography of the polycrystalline structure of the VB of the human eye by statistical and wavelet analysis.
Results: We obtained the numerical values of the change in the magnitude of the statistical moments of the 1-4 orders, which characterize the coordinate distributions of the magnitude of the linear birefringence (LB) of the polycrystalline component of the VB by the magnitude of the TSD. The results from our research illustrate the differences between the optical anisotropy of fibrillar collagen networks of VB layers with different TSD. The sensitivity range (36 hours) and accuracy (15 minutes) of the method of polarization tomography of the LB distributions of the polycrystalline component of the VB layers in the determined TSD were established.
Conclusion: These results confirm the experimental processes outlined accurately determine the time of death. In turn, will provide scientific evidence, specifications thereof, and objective expert opinion
THE IMPORTANCE OF THE INITIAL POSTPARTUM/ POSTNATAL HOUR AND SKIN-TO-SKIN CONTACT – A TIME FOR CHANGE IN BULGARIA.
No full textINTRODUCTION: This paper explores the practices surrounding skin-to-skin contact of mother and child immediately after birth within Bulgarian maternity wards and describes women`s experiences. It takes into consideration the research of Bulgarian experts in breastfeeding and contemporary recommendations for postnatal care worldwide.
Obstetric practices in local maternity wards are reviewed and evidenced by the research findings. The results put into perspective the different experiences that Bulgarian mothers have in local wards, and the authors explore these women`s attitudes towards the routine implementation of skin-to-skin contact in postnatal care.
The paper also outlines setbacks for introducing the practice in Bulgarian maternity wards due to the lack of midwife-led care and the importance of specialized care in optimizing health and a better understanding of skin-to-skin care.
OBJECTIVES: Purposes of this research are: (1) to explore women’s knowledge about skin-to-skin benefits, including their past experiences with the practice, and (2) to assess their own personal motivation and willingness to engage in the practice themselves.
METHODS: The methodology applied includes an online-based anonymous survey that aims to explore parents’ current levels of knowledge and gather their viewpoints regarding the practice. The research has been conducted on social media channels between the 26th of January 2020 and the 26th of February 2020 and includes women from varying local parent support groups: both respondents from a focus group, the area of Ruse, Bulgaria, and respondents from other major Bulgarian cities. The research findings are illustrated herein, and the authors discuss attitudes, as evidenced by the respondents’ opinions, expressed through the survey.
RESULTS: A total of 771 cases are included, which come from both groups. The research demonstrates common practices in local hospital wards are inconsistent with WHO recommendations and evidence-based medicine. Skin-to-skin care is practically a non-existent practice within immediate postnatal care, with most mothers separated from their baby during this crucial first hour(s). Almost all the women surveyed are willing to engage in, and embrace, skin-to-skin practices to be introduced as part of the routine within local maternity wards.
CONCLUSION: Midwives’ numbers in hospitals are dwindling, and women identify this is a worrying trend for the success of skin-to-skin bonding for new mothers. Evidence-based medical research and parental opinion compel us to rethink current postnatal practices, and therefore it is logical to suggest sustainable and realistic strategies for promoting and implementation of effective guidelines
EVALUATION OF EFFECTS OF CORRECTIVE EXERCISES ON PES PLANOVALGUS IN PRESCHOOL CHILDREN
No full textIntroduction: The foot forms the natural base of the human body bearing all its weight. Over the course of a person's life, the foot ensures the contact of the body with the terrain and creates the basic support during dynamic activities such as walking or running, especially on uneven terrain. (Véle, 2006)
Objectives: The aim of the research was to verify the effects of targeted corrective exercises on healthy foot development in preschool children.
Methods: The research was conducted from September 2018 to March 2019. The research sample consisted of 105 probands (59 preschool girls and 46 preschool boys), out of whom 7.62% had the physiological position of the arch on the right foot during baseline measurements. The average age of probands was 5 years. The measured parameters were the foot arch height without and with a load. Measurements were taken before and after rehabilitation intervention.
Results: The statistical analysis of the results confirmed the positive effect of rehabilitation treatment in all monitored variables on statistically significant diference in terms of an elevation in the foot arch (p <0.005) and the influence of risk factors contributing to the development of researched foot deformities. The obtained data were processed into tables and graphs and subsequently evaluated.
Conclusion: Our study has shown that the most effective is the active exercise strengthening. The affected muscles maintain the foot arch as well as the whole posture
DEVELOPMENT OF A POSTPROCESSOR FOR TURNING CENTER AND MULTI-TASK MACHINE WITH MULTI-CHANNEL CNC SYSTEMS
No full textThis article discusses the possibility of developing a postprocessor for turning center with 2 turrets and a multi-channel CNC system with NC program format characteristic of machine Mazak Integrex I series. Typical for these CNCs is the usage of two support programs - one for each turret. The CAD / CAM system PTC Creo is used to solve the problem, where tool transitions are developed for machining the workpieces. The postprocessor is software that translates the CL Data file i.e. turns it into a NC program with preparatory, technological, and supplementary commands to control the machine. G-POST, which is integrated into the PTC Creo CAD / CAM system, is used to develop the post-processor. To solve the problem, a specialized programming language FIL (Factory Interface Language) is used which, with its features and capabilities to work with files in ASCII code, achieves the ultimate goal - NC program in format characteristics suitable for machines Mazak Integrex I series
SOME ASPECTS OF THE MATERIALS’ OPTICAL LIMITING FEATURES
No full textDue to the effective use of the fullerenes and other nanoparticles in the materials for the general optoelectronic, laser and display technique, as well as for biomedicine, the different mechanisms to attenuate the light intensity are considered with good advantage in order to protect the human eyes and technical devises from high laser irradiation. Reverse saturation absorption, complex formation, scattering, etc. are taken into account. In the current paper the influence of the content of the nanoobjects on the interface relief is shown and considered as an additional possible optical limiting mechanism. Moreover, the diffraction from the nanostructured materials via high frequency Kerr effect is added to extend the numbers of the optical limiting mechanisms. Different experimental instruments and supporting models are presented. VIS lasers, AFM, OCA devises are applied to test and visualize the results. Theoretical and experimental data are in good coincidence
CLUSTERS, EUROPEAN POLICY IN EXCELLENCE OF MANAGEMENT
No full textThe European Union (EU) plays an important role in the developing of clusters, defined by the European Commission as groups of specialized enterprises – often SMEs – and other related supporting actors that cooperate closely together in a particular location. As a result, the EU launched the pan-European initiative to support cluster management (European Cluster Excellence Initiative). It recognizes the performance of cluster management by quality labels such as the Bronze, Silver, and Gold issued by The European Secretariat of Cluster Analysis. With reference to these certifications, the authors analyzed the cluster management excellence by critically studying the labels granted in terms of trends, numbers, sectors, countries, and regions. Based on the gathered results, the clusters initiatives (new or already existed) can benchmark themselves. Regional, national, and European policymakers will be able to estimate how specific factors of political, geographical, demographic, access to raw materials, and level of development can influence the number of clusters, their quality of management, and cluster typology. The goal of the research is to identify the number and type (bronze, silver, and gold label) of clusters in the EU and UK. As research methods, analyzes were performed using the European Cluster Collaboration Platform (ECCP) and European Secretariat for Cluster Analysis (ESCA) data. The main results of the research show that clusters differ not only in size or activity but also in quality. Most clusters are found in the rich countries of Western Europe. Most clusters in Europe that have a bronze label are often located on the Iberian Peninsula, the Balkans, and Central Europe
BULGARIA'S REAL CONVERGENCE IN THE CONTEXT OF POTENTIAL EMU MEMBERSHIP
No full textSince the entry of Bulgaria into the European Union, the country's full membership in the Economic and Monetary Union has become one of the national economic policy goals. In the recent period Bulgaria fulfils all the nominal convergence criteria, except for the criterion on exchange rate stability as long as the country does not participate in the ERM II mechanism (although Bulgaria has a currency board arrangement in place since 1997 and the Bulgarian currency is pegged to the euro). Despite that, Bulgaria remains the EU member with the lowest level of GDP per capita and lowest productivity and income levels. In June 2018 the Bulgarian authorities submitted a letter of intent to the EU policy makers to join the ERM II mechanism and the banking union. In July 2020 the mutual agreement to include the Bulgarian lev in the ERM II mechanism and Bulgaria to join the banking union was achieved. In the context of the future full EMU membership it is important to assess the evolution and the state of Bulgaria's real convergence. This paper looks at the Bulgaria's real convergence, understood as the convergence of GDP per capita, labour productivity and convergence of price levels. We use the Beta and Sigma convergence methods and explore the convergence in the 1999-2018 period. We also compare Bulgaria's real convergence to the real convergence of other CEE countries that are EU members (Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia), part of which have already accepted the euro and the other part are still outside of the euroarea. We also try to explain the economic reasoning behind the EMU accession path of Bulgaria. The results of the survey show that Bulgaria lags behind in its convergence process from other CEE countries, but at the same time we believe that the benefits of the euroarea membership outweigh the possible negative consequences
MACROECONOMIC FACTORS AND THEIR INFLUENCE ON THE VISEGRAD GROUP EXCHANGE RATES
No full textThe paper analyzes the effects of macroeconomic development on exchange rates and aims to point out indicators with a significant impact on the Visegrad Group's domestic currencies. Steep changes causing the Visegrad Group’s currencies to either appreciate or depreciate against the US dollar may result in higher risks for investors and even deteriorate the competitiveness of the particular country. The paper presents several macroeconomic indicators and their influence on four currencies, namely the Czech crown, Hungarian forint, Polish zloty and the Euro. As the Slovak Republic introduced the Euro as its official currency, the paper also analyzes it's impact on the common currency of the Eurozone. To emphasize international competitiveness, the research apart from traditional economic indicators, serving as a focal point in theories for exchange rate determination, incorporated economic complexity and corruption score as well. The findings indicate that during the period between 2000 to 2017, the two common indicators i.e. total reserves and corruption played the key role in determining the year-end spot exchange rates of the Czech crown, Hungarian forint and the Polish zloty. Besides corruption score, economic complexity serves as another significant indicator merely influencing the direction of the Euro's and the Zloty’s Dollar exchange rate movement. The last section compares the results of the OLS analyses for each country and verifies their accuracy through robust regressions. Overall, the model for the Czech crown represents the highest accuracy, regarding its predictive ability
