Contrasting Aspects in Noncompaction Cardiomyopathy
Authors: Ciobîcă Lucian-Mihai , Ionescu Oana-Petronela , Stanciu Silviu 
Published: April 2021

Abstract
Left ventricle noncompaction or noncompaction cardiomyopathy is a rare cause of cardiomyopathy, presumed to be the consequence of the cessation of the embryological phenomenon of progressive compaction of the ventricular myocardium (which normally occurs between the 5th and 8th week) with the persistence, to varying degrees, of prominent trabeculae and deep intertrabecular spaces Placed as an unclassified cardiomyopathy, this pathology is of interest due to different contrasting aspects observed in its evolution over time. The article reviews the etiopathogenic hypotheses, the diagnostic criteria according to the imagery used, the clinical forms of presentation and certain general principles of treatment. To illustrate the imagery used in this heart disease, the article has attached images of a case of noncompaction cardiomyopathy in a 26-year-old patient with left ventricular ejection fraction of 17% (measured by cardiac magnetic resonance imaging). Finally, the idea of the need for multicenter studies to establish whether this cardiomyopathy is an independent disease or a distinct phenotype which is not necessarily pathological is supported.
Two Pandemics Coalition: COVID-19 and Obesity
Authors: Hâncu Anca , Mihălţan Florin 
Published: April 2021

Abstract
COVID-19 epidemic caused by an influenza-like virus strain (SARS-CoV-2) invaded the world. The World Health Organization (WHO) announced this infection outbreak as a global pandemic on 11 March 2020. From one day to another the number of new cases is growing and also the number of deaths. This infection emerged earlier in Wuhan City and rapidly spread throughout China and around the world since December 2019. Another silent pandemic disease spreading mainly in industrialized countries is obesity. The best example is US were about 34% of the Americans are obese.
In actual context, it can be said there is a coalition of 2 pandemics. In Romania, obesity and overweight prevalence assessed by Predatorr study is at a high level: 34,7% overweight and 31,9% obesity. Systemic inflammation in obesity is the central mechanism leading to lung function decline. There are two main questions a) is obese more sensible to viral infection or b) potentially more contagious? The answer is positive to both. Recent WOF official position stated that obesity is a risk factor for developing severe forms of COVID-19. Donna Ryan’s message, as president of World Obesity Federation WOF,US emphasized at the beginning of April the risk for severe complications for persons with obesity who contracted the infection with SARS-CoV-2. Nutritional support in COVID-19 should prefer oral feeding, whenever is possible. A special attention should be dedicated to a healthy microbiome and intestinal immunity. Energy intake should be 25-30 kcal/body weight, with 1.2-2g/kg proteins. Enteral nutrition will be recommended in severe cases. Evidence is supporting the recommendation that for people at risk of developing COVID-19 to consider for few weeks a dosage of 10000UI/day of vitD3, than a maintainance dose of 5000 UI/day. The target must be to stabilize a level of 40-60 ng/ml for 25(OH) D concentration.Pulmonary rehabilitation, smoking cessation, included in a healthy lifestyle will be further steps after patients recovery from this infection. Facing this pandemic coalition, our messages should be stronger in stimulating prevention of obesity. Since more than a half of Romanian population is already overweight or obese, healthy lifestyle should become a daily prescription, not just a luxury recommendation. Daily, right messages from doctors acting like role models, in a partnership between general practitioner and other specialties like diabetologists, pneumologists, cardiologists, nutritionists will be efficient weapons against this cruel coalition: Obesity and COVID 19.

Comparative Analysis of the Banking Sector Competitiveness in Serbia and Montenegro
Authors: Grubišić Zoran , Kamenković Sandra , Kaličanin Tijana 
Published: April 2021

Abstract
Central banks often use certain concentration indices in their official reports to determine the degree of intensity of competition, of which the most common are the concentration ratio and the Herfindahl-Hirschman index. It is important to emphasize that when calculating the value of these indices, the National Bank of Serbia most often uses the absolute value of assets. In addition to the mentioned indices, the values of the Gini coefficient, Entropy coefficient, Rosenblatt index and graphical representation of the Lorenz curve in the period 2015–2019 are presented in this paper, using the balance sheet position loans and receivables from customers, but not including loans and receivables from banks and other financial organizations. The results of the static and dynamic analysis of concentration indicate that, compared to Montenegro, the banking sector of Serbia is characterized by a larger number of banks, less concentration on the market, and stronger intensity of competition. Although market changes are reflected in a reduced number of banks while a change in the dispersion of market shares affected the change in the market structures of the banking sectors, instability and uncertainty of the analysed sector remained unchanged in the case of both countries.
Does Monetary Policy Credibility Help in Anchoring Inflation Expectations? Evidence from Six Inflation Targeting Emerging Economies
Authors: Güler Aslı 
Published: April 2021

Abstract
Most emerging market central banks have adopted inflation targeting as their monetary policy system. The heart of inflation targeting system is inflation expectations. The success of a central bank in achieving targets depends on to the extent to which inflation expectations are formed by the announced targets. As the credibility of the central bank increases, its ability to affect the public expectation also increases. The public adjusts its inflation expectations based on announced inflation target only in case of that they believe that the central bank has the sufficiency to reach the inflation target. Credibility enables expectation to be formed in a forward-looking way by weakening its connection with the past. This study aims to contribute to the literature concerning the effects of credibility on monetary policy. For this purpose, using data of six emerging inflation targeting economies (Turkey, Brazil, the Czech Republic, Chile, Poland, and South Africa), the empirical tests were carried out in order to understand the effect of the credibility on the behaviour of inflation expectation in emerging economies. The findings denote that credibility is quite relevant to reduce inflation expectations and contributes to the strength of inflation targets being an anchor for inflation expectations.
A novel planar, broadband, high gain lateral wave antenna array for body scanning applications
Authors: Tokan Fikret , Cavallo Daniele , Neto Andrea 
Published: April 2021

Abstract
Three-dimensional body scanning systems are increasingly used in sensitive public areas such as airports. By providing a high resolution image of a person from all sides, it is possible to detect potential metallic, ceramic and explosive threats. For these systems, it is essential to design broadband antennas with a fan beam, highly directional radiation in one plane and wide in the other plane, and characterized by phase center stability as a function of frequency. In this paper, the planar lateral wave antenna (LWA) array is proposed to achieve these radiation requirements. The LWA has two critical shortcomings: the flaring part and the dielectric matching layers (MLs), to operate over very broad frequency bands. In this work, these shortcomings are overcomed by forming a connected array of planar LWAs to improve broadband performance and by applying necessary perforations on the dense dielectric lens antenna to create different effective relative permittivity regions. An eight element connected and perforated LWA array is designed to operate in the 8–24 GHz frequency band. The drilled holes are proved to play a similar critical role of MLs in internal reflection suppression. The results emphasize all crucial demands for body scanning systems.

Abstract
Life satisfaction, dimensions of internalized cultural values and self-efficacy related to emigration intentions for a long-term stay abroad of university students in five European countries.
Aim: To explore the associations between emigration intentions of university students form five European countries in relation to several intrapersonal and emigration self-efficacy. The second aim is to explore the mediating role of self-efficacy in relation to internalized cultural values and emigration intentions.
Sample and procedure: The sample consisted of 1223 students (females N=812, 66.4%, males N=411, 33.6%. M=21.95, SD=3.62) from five European countries. The data collection was completed via an online questionnaire (University of Antwerp, Belgium, Sofia University, Bulgaria, University of Miskolc, Hungary, Lithuanian University of Health Sciences, Lithuania, Pavol Jozef Šafárik University in Košice, Slovak Republic). The local ethics committee in every country approved the study
Statistical analysis: Statistical analysis was performed in SPSS 21. Differences in intrapersonal were analysed by ANOVA with a Scheffe Post hoc test. Binary logistic regression with the method enter controlling for country and age was used as a method of analysis. Mediational analyses were explored by using Hayes PROCESS tool.
Findings: The regression model explained between 29-38 percent of the variance. Those students with higher self–efficacy also with higher horizontal individualism were more likely to have emigration intentions compared to those with lower self-efficacy and HI, and those with lower satisfaction and vertical collectivism were more likely to have long-term emigration intentions compared to those with higher satisfaction and VC. Self-efficacy was found to mediate the relationship between horizontal dimensions of internalized cultural values and emigration intentions.

Abstract
This study investigated the impact of spaced and massed instruction on foreign language reading motivation and reading attitude among Iranian pre-intermediate EFL learners. To fulfil this objective, 60 Iranian participants were chosen among 120 students based on the results of Oxford Quick Placement Test (OQPT). The selected pre-intermediate participants were then divided into two equal experimental groups: spaced group and massed group. Afterwards, the researcher measured the participants’ reading motivation and reading attitude by administering a reading motivation questionnaire and a reading attitude survey as a pre-test. Then, both groups received the treatment. During the treatment phase of the study, the massed group was taught the reading comprehension in an intensive 60-minute session, while the spaced group was taught in three short sessions (twenty-minute session). After the instruction, a reading motivation questionnaire and a reading attitude survey as a post-test were carried out to both groups and finally the data were analyzed by running paired and independent sample t-tests. The outcomes demonstrated that there was a significant difference between the post-tests of spaced and massed groups. The findings indicated that the spaced group significantly out performed the massed group (p < .05) on the reading motivation and reading attitude post-test. The implications of this study make teachers know that teaching through spaced periods can produce better outcomes than teaching through one massed session.

Published: April 2021

Abstract

Introduction
Turkey histomonosis poses a serious threat to poultry production due to the ban on the use of effective drugs. The aim of the study was to evaluate the influence of a phytoncidal feed supplement on the course of histomonosis. The preparation was also analysed for immunomodulatory properties.

Material and Methods
Clinical observations and production monitoring were conducted in a flock of turkeys with histomonosis from their 11th to 56th weeks of life which were treated with the adiCoxSOLPF soluble supplement in a dose of 2.5 mL/L water. Later the preparation was used in a preventive dose (1 mL/L). The influence on the immune system was evaluated in broiler turkeys having been given adiCoxSOLPF for 3 days in doses of 1 or 3 mL/L. The T and B lymphocyte percentages in turkey blood and spleen tissue were analysed with flow cytometry. ELISA was implemented to evaluate antibody titres after Ornithobacterium rhinotracheale vaccination, and biochemical analyses were performed to evaluate the supplement’s safety.

Results
AdiCoxSOLPF was found effective in therapy and prevention of histomonosis. Additionally, adiCoxSOLPF stimulated both humoral and cell-mediated immune mechanisms, without impairing the functions of internal organs. The treated turkeys also yielded better production results (eggs/hen, fertility, and hatchability).

Conclusion
AdiCoxSOLPF possesses immunomodulatory properties and it can be used successfully in the prevention and therapy of histomonosis in turkeys.

Authors: Sieradzki Zbigniew , Mazur Małgorzata , Król Beata , Kwiatek Krzysztof 
Published: April 2021

Abstract

Introduction
Globally, genetically modified (GM) crops were grown on 191.7 million hectares in 2018, which were mostly sown with soybean, maize, cotton, oilseed rape, and rice. The most popular traits introduced through genetic modification include herbicide and pest insect resistance. The aim of this study was to identify and quantify genetically modified soybean used in animal feed in Poland.

Material and methods
This research was based on the real-time PCR technique. All methods for GM soybean events were adopted from the EURL GMFF database of methods and previously verified to meet the minimum criteria of acceptance. Over 15 years of research, 665 samples were examined in total.

Results
The most common GM soybean event was MON40-3-2, tested for from the beginning of the investigation. Next, in decreasing order of frequency, were MON89788, MON87701, and A2704-12. In the majority of samples (606; 91%) GM soybeans were identified at a content level above the 0.9% GM content threshold for mandatory labelling. Only 59 soybean samples (9%) were identified as GM negative. GM negative results were mainly identified during the analyses in the last three years of the study, from 2017 to 2019.

Conclusion
Our data clearly indicate that the majority of soybean used in Poland for animal feeding was genetically modified.
Evaluation of microstructure of the steels after exposure in supercritical CO2
Authors: Rozumová L. , Melichar T. , Berka J. , Velebil L. 
Published: April 2021

Abstract
The Brayton cycle with supercritical carbon dioxide is considered as an innovative technology with the potential to replace conventional steam cycles. The optimization of the supercritical CO2 cycle (sCO2) is necessary and important to achieve the required thermal cycle parameters. The above optimization focuses on the setting of the energy cycle as such, the design solution of the individual components and, the last but not least, on the selection of suitable construction materials. Due to the operating conditions, namely temperatures exceeding 550 °C and pressure up to 25 MPa, material research is one of the important areas of the research and development of sCO2 energy cycles. Construction materials for sCO2 power cycle equipment include HR6W, T92 and Haynes HR235 alloys. This work presents results of the corrosion test, in which samples of these materials were exposed to sCO2 at 550 °C and 25 MPa for 1000 hours. Corrosion after exposure was examined using a light optical microscope (LOM) and a scanning electron microscope (SEM). The significant differences in corrosion attack between the investigated materials and the formation of a protective oxide layer on the surface were observed.

Published: April 2021

Abstract
More and more international students come to Japan to study. Data shows that they tend to face learning related difficulties. Our study’s goal was to determine whether or not the English and Japanese hybrid class has created a multilingual and multicultural learning environment. Pre-instructional and post-instructional surveys were taken by the students taking the class, and the data was compared between high achievers and non-high achievers, and between Japanese students and international students. The results show that high achievers and non-high achievers, and Japanese students and international students all had positive perceptions of the class contents and instruction in Japanese and English. These findings tell us that the English and Japanese hybrid class provided meaningful and purposeful opportunities for creating a multilingual and multicultural learning environment for all groups and students. This was achieved by contextualizing relevant and appropriate topics and themes, such as social and cultural characteristics and issues of Japan and utilizing the target languages of English and Japanese for hybrid instruction.
Dancing Towards Personal and Spiritual Growth
Authors: Schuff Hildegunn Marie T. 
Published: April 2021

Abstract
This paper explores the place where dance and religious faith meet. It gives examples of learning experiences and processes of personal and spiritual growth that occur there. The paper is based on a study of dance in Christian contexts in contemporary Norway, that is part of the RESEP (Religion as Aestheticizing Practice) research project based at the University of Agder, Norway. The empirical material is based on participant observation of dance in churches and other Christian settings and on interviews with approximately 50 dancers in these settings. Dance provides the participating dancers with multidimensional meaning and perceived benefits. Through narratives and quotations, the paper sheds light on three ways in which the dancers in question experience processes that lead to growth through dance: 1) as a holistic and attractive way of learning and communicating, 2) as personal growth; by mastering dance through self-expression in a supportive environment, expressing and processing emotions, and moving towards better mental and physical health and wholeness, 3) as spiritual growth; by providing an interface with God that strengthens one’s listening to both God and oneself, and as a way of living their faith in interaction with others.
«Historia är något som konstrueras, det här är ett val» – om kritisk granskning i danshistorieundervisning
Authors: Samuelson Saga 
Published: April 2021

Abstract
This article examines and discusses how teachers at upper secondary school relate to teaching dance history within the course Dance Theory, focusing on the aim that students critically examine various dance history writings. The study uses interviews and open-ended questionnaires, and the material has been analysed qualitatively and discussed in relation to historiographical and norm-critical perspectives. The study shows that a historiographic perspective is important to teachers when they describe their teaching but less important when describing what they think students should gain from their studies. Instead, a general knowledge of dance history and an ability to connect one’s dancing to a historical context are central. The norm-critical perspective is manifested mainly in the teachers’ positioning of themselves, but as I understand it, the critical examination primarily lies within the norm rather than providing a means of looking outside the Western box. The next challenge is therefore to not only review the conditions in which history is created but also question and change the structures that create knowledge.
Daring in dance–Bachelor Students in Dance Developing Life Skills for the 21st Century
Authors: Rothmund Irene Velten 
Published: April 2021

Abstract
This article investigates how to find connections between dance education and the development of life skills for the 21st century by interpreting students’ experiences of daring in dance. The article draws on a section of my PhD thesis that focuses on BA students’ lived experiences in modern and contemporary dance. The project is informed by hermeneutic phenomenology, and the material consists of eleven students log books and interviews. One of the main themes in the material is daring in dance, which is connected to a transformative learning process. In this article I dig more deeply into the embodied dimension of such learning process and discuss how the result of this process can be interpreted as developing life skills for the 21st century. The analysis shows that becoming a professional dancer is a vulnerable process, encompassing both fear of failure and learning to trust one’s own competencies. Several of these competencies point toward skills recognised as important to learning in the 21st century, such as flexibility, problem solving, self-direction and social skills. By focusing on everyday embodied experiences of daring in dance, this research provides one example of the development of life skills in higher education based in empirical research.

Published: April 2021

Abstract
A comparative analysis of factors of vacuum rail’s competitiveness in Poland relative to other means of transport is presented. Only such determinants of competitiveness as price and time of travel are focussed on and compared with alternative solutions on selected routes. Impact of price changes on effectiveness of vacuum rail construction is additionally analysed. Investment effectiveness in the case of vacuum rail is considered in the long time-frame, given the time of infrastructure depreciation and of due return on sources of committed financing. The analysis helps to identify key factors which may decide competitive advantage of vacuum rail in Poland over other means of transport.
