Published: April 2021

Background

Patients with left breast cancer who undergo radiotherapy have a non-negligible risk of developing radiation-induced cardiovascular disease (CVD). Cardioprotection can be achieved through better treatment planning protocols and through respiratory gating techniques, including deep inspiration breath hold (DIBH). Several dosimetric studies have shown that DIBH reduces the cardiac dose, but clinical data confirming this effect is limited. The aim of the study was to compare the mean heart dose (MHD) in patients with left breast cancer who underwent radiotherapy at our institution as we transitioned from non-gated free-breathing (FB) radiotherapy to gated radiotherapy (FB-GRT), and finally to DIBH.

Patients and methods

Retrospective study involving 2022 breast cancer patients who underwent radiotherapy at West Pomeranian Oncology Center in Szczecin from January 1, 2014 through December 31, 2017. We compared the MHD in these patients according to year of treatment and technique.

Results

Overall, the MHD for patients with left breast cancer in our cohort was 3.37 Gy. MHD values in the patients treated with DIBH were significantly lower than in patients treated with non-gated FB (2.1 vs. 3.48 Gy, p < 0.0001) and gated FB (3.28 Gy, p < 0.0001). The lowest MHD values over the four-year period were observed in 2017, when nearly 85% of left breast cancer patients were treated with DIBH. The proportion of patients exposed to high (> 4 Gy) MHD values decreased every year, from 40% in 2014 to 7.9% in 2017, while the percentage of patients receiving DIBH increased.

Conclusions

Compared to free-breathing techniques (both gated and non-gated), DIBH reduces the mean radiation dose to the heart in patients with left breast cancer. These findings support the use of DIBH in patients with left breast cancer treated with radiotherapy.

Introduction. Upper digestive tract endoscopy remains the gold-standard for detecting esophageal or gastric varices and assessment of bleeding risk, but this method is invasive. The aim of the study was to identify non-invasive factors that could be incorporated into an algorithm for estimating the risk of variceal bleeding.

Methods. A prospective study was performed on 130 cirrhotic patients. Tests were performed on all patients which included liver enzymes, complete blood count and coagulation parameters, abdominal ultrasound, elastography of both the liver and the spleen. Upper gastrointestinal endoscopy was performed in all patients included in the study and the results were classified, in accordance with Baveno VI into 2 outcome groups: Group 1 – patients with low bleeding risk and Group 2 – patients with varices needing treatment.

Results. The study lot (130 patients) was divided into: Group I (low bleeding risk – 102 patients), and Group II (high bleeding risk – 28 patients). Parameters found to have significant differences in univariate analysis were transaminases, platelet count, spleen size, INR, portal vein diameter and both liver and spleen elastography. Calculating AUROC for each parameter identifies spleen elastography as having the best result, followed by INR, AST and platelet count. Liver elastography had the worst AUROC. Independent variables identified by logistic regression included spleen elastography, INR, platelet count, spleen diameter, ALT, age, and gender.

Conclusions. Spleen stiffness is the best single parameter predicting the presence of high-risk esophageal varices.

Published: April 2021

Introduction. Hemodialysis (HD) patients have higher mortality rate than the general population. Recent studies indicate a significant role of non-cardiovascular risk factors in for mortality in HD patients. Leptin is protein hormone and may indicate malnutrition in HD patients. Its role in mortality in these patients is being examined. This study aimed to investigate the correlation between serum leptin levels and non-cardiovascular risk factors and relationship between leptin level and mortality in HD patients.

Methods. The prospective study included 93 patients on maintenance HD and follow-up period was 12 months. We measured leptin level and evaluated non-cardiovascular risk factors: nutritional status, anemia, volemia, parameters of mineral and bone disorder.

Results. Out of 93 patients 9 died during study and 1 underwent kidney transplantation. Malnutrition and hypervolemia were two main non-cardiovascular risk factors among deceased subjects. Leptin showed a significant direct correlation with nutritional BMI (r = 0.72, P < 0.001), fat tissue index (r = 0.74, P < 0.001) and statistically significant inverse correlation with leantissue index (r = -0.349, P < 0.05) and inverse correlation with volemic parameters (overhydration / extracellular water ratio (r = -0.38, P < 0.001), but no association with anemia and mineral bone parameters was observed. Elevated leptin levels were associated with better survival. However, no statistically significant difference in survival rates was observed between the study groups (Log-Rank P =0.214, Breslow P =0.211, Tarone-Ware P=0.212).

Conclusion. Deceased patients had significantly lower leptin values. Leptin was associated with two non-cardiovascular risk factors for mortality: malnutrition and hypervolemia.

Published: April 2021

Sepsis and septic shock are considered major factors in the development of myopathy in critically ill patients, which is correlated with increased morbidity rates and ICU length of stay. The underlying pathophysiology is complex, involving mitochondrial dysfunction, increased protein breakdown and muscle inexcitability. Sepsis induced myopathy is characterized by several electrophysiological and histopathological abnormalities of the muscle, also has clinical consequences such as flaccid weakness and failure to wean from ventilator. In order to reach definite diagnosis, clinical assessment, electrophysiological studies and muscle biopsy must be performed, which can be challenging in daily practice. Ultrasonography as a screening tool can be a promising alternative, especially in the ICU setting. Sepsis and mechanical ventilation have additive effects leading to diaphragm dysfunction thus complicating the patient’s clinical course and recovery. Here, we summarize the effects of the septic syndrome on the muscle tissue based on the existing literature.

Published: April 2021

This paper evaluates the possibility of using artificial aggregates from blast furnace slag, considered industrial waste, which can replace, in a certain dosage, the natural aggregates in the composition of an AB 22,4 asphalt mixture. Furthermore, it is presented the possibility to replace the usual filler with powders from industrial wastes such as the desulphurization waste, generated by the combustion of the energetic coal.

Laboratory studies and researches are carried out according to prescribed techniques. For this purpose, for the evaluation of the performance of the asphalt mixture recipes will be evaluated by static and dynamic tests as described in AND 605: 2016.

The results of this study show the possibility of using asphalt mixtures with different dosages of industrial wastes in composition.

The results obtained from the laboratory tests have shown that materials from industrial waste can be used in the design of asphalt mixtures with the purpose of replacing natural materials, used in certain dosages, which demonstrates good behavior in interaction with the usual bituminous binder.

Published: April 2021

Energy efficiency policy has been one of the European Union top priorities for decades and will continue to play a vital role in the next 10 years with the introduction of The Clean energy for all Europeans. Likewise, in Latvia energy efficiency has been given high priority; however, the energy efficiency targets for industry has lacked ambitions. This research focuses on evaluating the Latvian industrial energy efficiency policy using top-down approach and benchmarking energy intensity of Latvian industry to the average of the European Union’s. Results confirm that on average Latvian industry consumes 2.6 times more energy to produce the same amount of value added compared to the average in the European Union; however, every saved energy unit in Latvia would save twice less CO2 emissions considering already largely decarbonized energy mix. In the spotlights of the Green Deal proposed by the European Commission, much higher contribution in terms of CO2 reduction and energy efficiency will be expected from the industry. Nevertheless, energy efficiency targets for Latvian industry should be sector-specific, separately addressing CO2 intensive sectors, and non-intensive CO2 sectors with low added value.

For food industry, the production of functional pasta from non-conventional raw materials represents a challenge. This study aims to evaluate the potential of animal proteins of freeze-dried whey as a component for pasta production and its effect on the pasta qualities and consumer acceptance. Sweet whey was freeze-dried, then directly incorporated to pasta at a 20% level. Two pasta types (pasta non-enriched vs. enriched with whey powder) were manufactured following a small-scale pilot procedure, and then evaluated for their physicochemical and sensory qualities. Results of all analyses (whey, semolina and pasta) met the standards according to international legislation; however, the characteristics of enriched pasta differed. Whey addition significantly increased ash, proteins content, optimal cooking time and water uptake (P < 0.05); it significantly decreased moisture levels, colour parameters (CIE system: a* redness, b* yellowness) and the swelling index (P < 0.05). Sensory analysis revealed that overall sensory and product quality of enriched pasta was not affected by whey fortification and it was found acceptable by panelists. This study points out that whey powder could be used for the functional pasta production to increase proteins levels.

Published: April 2021

Studies in different countries comparing the quality of education in private and public schools have used a variety of measurement methods to determine educational quality and findings have been mixed. For the unique situation of Greece, the variable of student admission to the Greek university system, depending on whether the student’s secondary education was in the public or the private system, provides an apt outcome variable to measure relative educational quality. We provide estimates of the effect of private secondary schooling in Greece on students’ admission to their preferred university academic department, using data from nationwide surveys conducted identically in 2000 and 2015. This repeated-measures research design allowed us to compare the same set of factors between the two administrations, thus examining for the stability or change of their contribution over time. Our final sample consisted of 4740 secondary school students. We used a weighted questionnaire to investigate the effect of private schooling on the trajectory to university. In our empirical model, a multinomial logistic regression was performed to classify subjects based on values of a set of predictor variables. Results indicate that attending a private high school offers secondary education students a significantly higher probability of stepping successfully into an academic department of higher relevance to their academic preferences and future career expectations. We also find that private high school education significantly minimizes the efforts required for a student to enter a desirable university department. Positive correlations between the attendance of private high school education and demographic attributes of both students and their families were also found. Research and policy recommendations are included.
Comparing the Impact of the Net Income Versus the Comprehensive Income Over the Share Price for Companies Listed on the Bucharest Stock Exchange
Authors: Ioana Pop
Published: April 2021

As a consequence of adopting the IFRS in Romania, starting with 2012, for companies whose securities are admitted for trading on a regulated market, financial reporting demarches include ascertaining the comprehensive income in addition to the net income. The present paper aims at investigating how the share price evolves considering the level of the comprehensive income as compared to the reported net income, in a multiannual empirical study implying panel data analysis through Pooled OLS, Fixed Effects and Random Effects models processed through EViews. Furthermore, the informational and decisional utility of the two main forms of disclosed accounting results (the net income and of the comprehensive income) is examined through a sample of 57 notable companies listed on the Bucharest Stock Exchange. Admittedly, the empirical study findings substantiate the fact that both results categories are significantly associated with the evolution of the share price, rendering a heightened value relevance for the Romanian capital market investors. Moreover, the identified results indicate that from an investor standpoint, the comprehensive income does not bear a greater significance than the net income, the two having comparable impacts over the share price.

The Greek economic activity has been declined dramatically in recent years as many sectors of the economy that cannot cope with the new state brought about by the economic crisis. An economic crisis can be described as the phenomenon when an economy is characterized by a continuous and noticeable decline in its economic activity. As an economic activity, we are referring to all the macroeconomic dimensions of the economy, such as employment, the national product, prices, investments, etc. The downturn in the supermarket sector, which is attributed to the country’s financial situation, has led to a decline in the household disposable income. The present study was carried out at the time of the economic crisis, concerning a productive sector of the Greek economy, where millions of euros are exchanged hands. The objective of the study was to explore the impacts of the economic crisis on the sector by using a series of financial indicators. The results point to significant effects on the efficiency and earnings of the major actors of the sector.

Published: April 2021

The basis of coronavirus disease is an infectious process, accompanied by a varying degree of activity of pathological processes. Based on the study of the pathological course of infection, modern approaches to the treatment and prevention of complications of coronavirus infection are presented. The main strategic pathogenetic direction in the creation of effective programs for the treatment of COVID-19, as well as the prevention of fatal complications, should be a set of measures enhancing permissive regulatory influences and events. Endothelium, being a source of inflammatory mediators and a transducer of their regulatory effects on the vascular tone, is involved in the development and alternation of vascular reactions, changing the volume of perfusion. The main mechanism for the development of endothelial dysfunction and damage is associated with an imbalance between the generation of reactive oxygen species and the power of the antioxidant defense system. Any measures to protect the endothelium, reducing the severity of microcirculatory disorders and hypoxia, will have a therapeutic and preventive effect on fatal complications. In this regard, in the treatment of COVID-19, the use of synthetic gas transport preparations based on perfluorocarbon nanodispersed emulsions with a clinical effect directed at once to several patho-genetic links underlying the progression of COVID-19 disease can be quite effective. The necessity of a comprehensive effect on pathogenesis using sanogenetic principles of treatment, allowing influencing the speed and time of onset of resolution of inflammation, which can reduce the number of complications and deaths of the disease, is substantiated.

Published: April 2021

Objective

The objective of the study was to analyse and compare the subjective quality of life (S-QoL) of women with physical disabilities (PDs) through satisfaction with the quality of life domains and the overall quality of life assessment.

Methods

The sample comprised of women with PDs (n=137), divided into 4 age categories: 19-29 yrs. (n=53); 30-44 yrs. (n=25); 45-59 yrs. (n=24) and over 60 yrs. (n=35). The Subjective Quality of Life Analyses questionnaire and the WHO User Manual were used as a primary research method. The Wilcoxon Signed Rank Test was used to assess the differences between QoLDs, Kruskal Wallis test to assess differences in S-QoL among four independent groups and Mann Whitney U-test between two age categories.

Results

The highest satisfaction in all age categories of women was found in the social relations domain, and in the 19-29 yr-old women equally in the social relations and physical health domains. The highest dissatisfaction was reported with the psychological health and environment domains. The key finding is that the main differences are between the youngest category (aged 19-29 yrs) and the three older categories with regard to physical health, environment and overall QoL.

Conclusions

It is necessary to continue this line of research with a greater focus on exploring the ways in which the psychological health domain can be improved as an integral part of S-QoL, and to also focus on the QoL indicators that make up the environment domain and search for ways to enhance these.
Design and Analysis Methods for Composite Bonded Joints
Authors: Dobrzański Przemysław , Oleksiak Witold
Published: April 2021

A literature review on existing design and analysis methods for composite adhesively bonded joints has been conducted. Methods that might form a basis for development of practical engineering methodology for adhesively bonded joints were selected and described. Starting from the simplest and the fastest analytical methods (closed-form solutions): average shear stress, shear lag model and adhesive beam model through more complex and more time consuming numerical methods supported by finite element analysis: global models, local models, cohesive zone models. Assumptions and applicability of each method was discussed. Simple and fast methods in order to be reliable have to include many conservative assumptions and therefore may lead to over-designed structure (weight penalty). Structural optimization and weight reduction require the usage of more complex and time consuming methods. Therefore, selection of adequate methods should always be balanced against strength, durability, costs and weight.

COVID-19 represents not only public health emergency but has become a global economic problem. It has affected all economic sectors threatening global poverty. The important question that arises is what catalyses the spread of the disease? In this paper the relationship between population density and spread of COVID-19 is observed which is goal of the paper. For the purpose of the analysis the correlation between the population variables and COVID-19 variables on a global country level (209 countries) and regional level of individual countries with the most cases of infection is observed. The results have shown that on a country level variable population is statistically significant in all regression models for total cases, deaths and total tests variables whereas variable population density was not. The research results from this paper can be important and relevant for economic and health policy makers to guide COVID-19 surveillance and public health decision-making.
Iranian Women’s Veiling as a Gender Performance: Since Premodern Era to the Current Age
Authors: Khadem Makhsuos Hosseini L.
Published: April 2021

Iranian women’s veiling, as one of the major concerns of both women and the state, has been the subject of various studies. The present study in its broad range of investigation covers discussion of Iranian women’s hijab since pre-modern Iran to the current age. Meanwhile, it is more than a new historicist reflection on the way discourses construct norms. Here, within the framework of Butler’s performative theory, veiling is approached as a gender performance, which constructs and represents the identity of the wearer. The question is how Iranian women’s veiling as a gender performance is associated with competing discourses, and how recitations of veiling give them agency. It is hypothesized that women are not simply imposed the norm of veiling by the dominant discourses; rather, as active agents they can change the norms as they perform deviated recitation of norm of veiling. Veiling as a signifier has given different significations in each era, ranging from modesty, backwardness, nationalism, revolutionary, to displaying protest. We address the meanings that different dressing styles represent in three eras of pre-constitutional, post-constitutional, and postrevolutionary in Iran. Homogenized imposed veiling by Islamic authorities in pre-modern Iran, withdrew with secularization of state, was invoked as sign of revolution against the state, re-imposed by the state and ultimately fashioned by women. Thus, veiling in Iran is burdened with more cultural and even political meaning. In each discourse, the performance of veiling style defines women’s subjectivity as normal or abject. Women to be identified as viable subject perform the norms of religious or secularized modern discourse. The two produced binary polar, representing two kinds of subjectivities produced a gap between veiled, unveiled women or properly veiled and misveiled women. The imposed, removed and re-imposed hijab has not been the terminal decision of discourses. It is confirmed that today, Iranian women, supplied with education and global media can reflexively consider and fashion their identity. Nowadays, Iranian women’s fashion hijab is a deviated recitation of the idealized norm to resist the imposed norm. Fashion hijab as a deviated recitation of originally intended hijab by Islamic state is a threat to the Islamic discourse. Therefore, it is regarded as soft war imposed by Western culture on Iran. It is concluded that there has been a dialectical relationship between veiling performance of subjects as agents and viability of the dominant discourse.
The Role of the Museum Space Narrative in Constructing Historical Memory
Authors: Voronina A. I.
Published: April 2021

The paper concerns the issue of representation of historical memory. The museum is analyzed as the particular site of emergement of such a representation. The circulation of specific narratives belonging to a museum is viewed as the research object that is able to provide insights into the construction of historical memory. Therefore, the purpose of the undertaken study is to identify the role of the museum narrative in the formation of memory. This article focuses on the ways of exposing and assessing the effect that museum exhibitions and the concepts and the meaning they translate to the audience have on memory creation. The approach of the interdisciplinary scholar field of memory studies provides a framework for such an analysis. In particular, since the spatial dimension of memory is concerned, the contributions of Hayden White and of the theory of realms of memory of Pierre Nora are crucial. The text deconstructs the memory formation processes taking place in the space of museums using these theoretical and methodological ideas. The paper meets methodological challenges and research questions with conducting a case study. The exhibition of the Museum of the Mologa District that is a part of the Rybinsk State Historical, Architectural and Art Museum Preserve at the Russian Yaroslavl Region serve as the source of oral, textual and visual narratives. This museum offers a view on local history that is in a way unusual for Russian museums — it provides a less formal perspective, and, in addition, the museum was founded by an initiative group of the displaced people from the submerged town of Mologa. The museum displays are dedicated to this town that disappeared because of the construction of the Rybinsk hydroelectric power plant. With limited material evidence to illustrate the Mologa life, this role is passed to oral histories and memory narratives. Thus, based on the historical memory literature, the paper considers that the museum described could be characterized as a memory museum, different from traditional historical museums because of emotional links in the presentation of past events. The author concludes that the image of the flooded city presented in the museum is directly related to the traumatic nature of the social memory of the settlers. Thus, the meanings and the significance of the museum overflow to the realms of memory.
Poetry and its Audience in the Digital Age
Authors: Smolskaya E. P. , Barteneva A. S.
Published: April 2021

The study assesses the influence that new technologies, relative to the poetic content and poetry as art, have on the field of public relations. The main trends in the development of modern poetry as an object of online promotion, the ties connecting the digital format as such to this specific genre and the methods of modern media promotion are concerned as the key research areas. Digital technologies have produced profound changes in society and in the sphere of media. The impact of online tools and infrastructure both on poetry itself and for the methods on its promotion is also relevant. One should note, the digital reality does not necessarily require the flattening of style, the dominance of prose — poetry remains viable. Moreover, in the era of digital devices and the growing dominance of web technologies, poetry acquires new meaning and significance both as an art form and as a traditional need, which can be attributed to the domain of the spiritual. The adaptation to the digital reality shapes poetry in several aspects. This trend is reinforced by the development of traditional poetry as a type of multimedia content and the proliferation of poetry in social networks. The promotion of poetry has received little attention in both Russian and international academic contexts. PR in poetry is usually examined in broader or related frameworks, such as art marketing or publishing. This approach disregards the specificity of poetry as an art form. The available data lacks consistency, and the overwhelming majority of the relevant articles relate to popular science and journalism, not scientific literature. The analysis shows that in the modern age, poetry is pivoting on new platforms, online, while poetic content is actively integrating with the multimedia format. Poetry is able to address themes and ideas that resonate within new generations, thus remaining alive and proliferating. This finds proof in the context of online texts: they acquire the status of media which integrate traditional art patterns with the commercialized and blog-oriented digital art forms and industries (visual arts, music, etc.). This process manifests itself in the growing popularity of poetry among the youth, digitally. New methods of monetizing poetry are emerging, thus increasing the attractiveness of a poetic career.
Religious and Philosophical Concept of Semyon Frank in the Context of Western Christian Theology
Authors: Dolin V. A.
Published: April 2021

The article examines the theological concepts of Semyon Frank that derive from the system of Nicholas of Cusa’s Neoplatonism. The ideas of Frank are problematic in origin, as they are attributed to different religious traditions. The paper disputes the compliance of the Frank’s Cusa-like Neoplatonism with the provisions of Catholic theology. The methodological foundation underlying the research is based on method of content reconstruction and historical and comparative method. With the view to scrutinizing the ideas of theologians, the content of Frank’s concept was reconstructed. It presents God as a spiritual Absolute and focuses on the problem of the balance stroked between God and the world, human beings and society as a whole. The leading methodological idea applied by Frank is the principle of antinomic monodualism as the coincidence of opposites in the formula unity of two or duality is one. Theological steps of argumentation in favour of the religious philosopher’s keeping aside of the Catholic path are as follows. Firstly, the critical attitude the philosophy of Nicholas of Cusa takes when facing the Catholic philosophy of those times serves as the evidence base and the obstacle for Frank to become a close ally of the Catholic thought. Secondly, the article notes the criticism Semyon Frank has of the Augustinian proposition about the insignificance of human being before God, which is foundational for Catholicism. Third, the article substantiates the compatibility of Frank’s ideas with the Orthodox ideal of sobriety and the system of external change of human being as the foundation of the system of Orthodox education and selfimprovement, thus obscuring the thoughts of his ties with Roman Latinism. Another research line treats the common features philosopher has with the third Christian confession. When comparing Frank with the Protestant theology, parallels occur (i.e. the Frank–Niebuhr Christian realism), but they are insufficient to claim the Protestant turn of Semyon Frank. As a result, it is concluded that Frank’s religious and philosophical conception is a theology of philosophical theism developed by a bearer of the Orthodox faith, not Catholicism. In relation to Orthodox theology, it is a soft, non-radical version of Orthodox modernism, in which solutions of problems that were contemporary to Frank are combined with maximum possible preservation of the provisions of the Orthodox theology.

Authors: Kim I. V. , Penyugina E. N. , Barsukova I. M. , Minnullin R. I.
Published: April 2021

Relevance. Among the purposes and target indicators of the implemented National projects by the end of 2024 it should be noted increase in the expected duration of healthy life, increase in total coefficient of birth rate up to 1.7 on one woman which achievement is impossible without ensuring female health.

The purpose: the analysis of a flow of the patients of an obstetric and gynecologic profile coming to a versatile hospital of emergency medical service (2015–2019).

Methodology. Data of the versatile 800-bed hospital incorporating 60 beds for patients of an obstetric and gynecologic profile served as materials of a research. Statistical and analytical methods of a research are used.

Results. The analysis of the entering stream (36.4 thousand in 5 years) with the diagnosis on the “obstetrics and gynecology” profile (the diagnosis of the direction) showed that most of them —  50.6% (р<0.01) were directed by the medical organizations of emergency medical service, 36.3% —  the medical organizations of polyclinic link, 3.2% —  the medical organizations of stationary type, and 9.8% —  independently asked for medical care. 77.6% of patients arrived from 9:00 till 21:00, including 32.9% —  from 9:00 till 12:00; the condition of 94.3% is regarded as satisfactory (р<0.01), only 71.5% of patients came to specialized offices according to a direction profile. The average time of stay of patients in office was about 2 hours (121.2±117.0 min.).

Conclusion. Development of stationary offices of emergency medical service gives the chance of sorting of the arriving patients according to weight of a state and needs in specialized medical and diagnostic actions. The diagnosis only of 71.5% of the arriving patients corresponds to a direction profile. The share of patients (for 50.2%), capable to ask independently for medical care grows.

Aim. To conduct the marketing analysis of the frequency and causes of the irrational use of medicines according to the assessment of the Ukrainian pharmacists, participation of pharmacists in promoting the rational use of drugs, and identifying appropriate measures to improve the situation.
Materials and methods. To achieve this goal, a survey of pharmacists from different regions of Ukraine was conducted, 420 questionnaires were selected and processed.
Results. According to pharmacists, such types of the irrational use of drugs as false self-medication, polypharmacy, and the use of expensive drugs in the presence of cheaper alternatives are the most common in Ukraine. The most important reasons for this phenomenon are uncontrolled self-medication, the impact of advertising and the availability of many over-the-counter medicines. The Ukrainian pharmacists take certain measures to influence on the rational use of drugs: refusal to dispense medicines, supplement to the doctor’s prescription, correction of the duration of treatment, and others. When counseling pharmacy visitors the largest number of respondents provide information on the way, frequency and duration of taking a medication, the smallest part – recommendations for a healthy lifestyle or non-pharmacological recommendations for the treatment. The respondents consider compliance with the rules of dispensing prescription medicines, training and advanced training of pharmacists throughout their professional career, and limitation of excessive advertising of medicines as the most appropriate measures to promote the rational use of medicines.
Conclusions. The results of the research reflect the peculiarities of the Ukrainian pharmacy practice regarding the participation of pharmacists in promoting the rational use of medicines.
Key words: rational use of medicines; pharmaceutical care; pharmaceutical consulting; good pharmacy practice.

Authors: Cartaxo Simone Regina Manosso , Scos Josemary
Published: April 2021

O texto analisa o processo de produção da prática pedagógica das professoras alfabetizadoras iniciantes a fim de contribuir para o seu processo formativo. O referencial teórico está fundamentado na compreensão da teoria como expressão da prática (MARTINS, 1996). A pesquisa é qualitativa e a análise fundamentou-se em Bardin (2011). Os dados foram obtidos por meio de questionários aplicados em 40 escolas de uma Rede Municipal de Ensino e entrevistas semiestruturadas com 17 professoras. Os resultados indicam que a prática pedagógica das professoras se constitui por desafios, por determinantes externos e internos e estratégias produzidas a partir dos problemas originados na prática. O processo formativo dessas professoras requer ampliação dos espaços coletivos de trabalho e compreensão da especificidade da alfabetização.

This study aims to determine the factors that influence users in using electronic money in transactions. The Unified Theory of Acceptance and Use of Technology (UTAUT) is used as a research model with independent variables: performance expectations, facility conditions, social influence, expectations, perceived values, habits, beliefs, and hedonic motivation. The dependent variable in this study is actual use and interest to be used as a mediator variable. This research method uses an online survey method that is distributed using Google Surveys. This study's sample was 194 electronic money users spread across three major cities in Indonesia, such as DKI Jakarta, West Java, and Central Java. Primary data collected were analyzed using SmartPLS software. The study results explain that trust is a substantial factor in influencing the use of electronic money. Companies, in this case, must pay attention to system security factors to be able to attract millennials using electronic money.

Integrated estimation of parameters of radio transmitter power amplifier with automatic mode adjustment by two-frequency test signal
Authors:   Omsk State Technical University, Sak P. V.
Published: April 2021

Comparative estimation of energy parameters of power amplifiers of single-band radio transmitters using automatic mode adjustment using a deterministic two-frequency test signal instead of a random single-band signal modulated by speech is investigated in the work. Relationships are found that allow judging the power consumption of the terminal stage of the power amplifier with automatic mode adjustment under various types of modulation based on the results of measurements obtained during tests. The ratios between the power consumption of the output stage when amplifying the random speech signal and amplifying the deterministic two-frequency test signal are obtained both without taking into account losses in the controlled power supply and taking into account such losses. Method is proposed for calculation of energy gain and efficiency factor (efficiency) when applying automatic control of supply voltage of output cascades of shortwave transmitters intended for modulation with speech signals. The loss in the regulated power supply has been estimated. The advantage of power amplifier circuits with automatic mode adjustment is justified

Objetivo: Revisar e refletir acerca da importância da realização dos exames de rastreamento do Câncer colorretal (CCR). Revisão Bibliográfica: O CCR é uma neoplasia que acomete o intestino grosso, sendo responsável por números crescentes de óbitos nos países Ocidentais. Nesse cenário, temos que no Brasil, com exceção do câncer de pele não melanoma, essa neoplasia maligna apresenta incidência alta, sendo o segundo tipo de câncer mais prevalente nas mulheres e o terceiro mais prevalente nos homens. A maioria dos tumores são de causas esporádicas e podem ser evitados pela prevenção primária através de uma dieta equilibrada e prática regular de atividade física. Além disso, surge nesse contexto um destaque para a prevenção secundária, pois a utilização dos exames de rastreio e as campanhas voltadas para a identificação precoce são ferramentas essenciais para se evitar a progressão da doença na sequência adenoma-carcinoma. Considerações finais: Apesar da elevada incidência no país, o CCR é uma enfermidade curável quando detectada nos estágios iniciais. Dessa forma, desenvolver novos estudos sobre os métodos de pesquisa, diagnóstico e rastreamento, buscar o aprimoramento profissional e estabelecer políticas públicas eficientes nas campanhas que abrangem a prevenção secundária são estratégias significativas no combate à essa doença silenciosa.
