Authors: Khalifeh Ala’ , Mansour Ma’moun , Alouneh Sahel 
Published: April 2021

Abstract
With the ever increasing demand for higher speed internet connectivity that can fulfil the application continuous need for higher bandwidth Google being the pioneer in many web-based services has launched a new UDP-based protocol named quick UDP internet connections (QUIC), which aims at providing faster data delivery without requiring upgrades or modifications to the network infrastructure. The goal of this paper is to provide an overview about QUIC protocol, propose the design and implementation of a test-bed, that is used experimentally to evaluate QUIC protocol under different network conditions and scenarios. In particular, the performance advantage of QUIC in terms of delay and throughput are examined taking into account different network conditions that resemble the real internet environment. Two scenarios are proposed, the first one investigates the protocol performance under a controlled network environment, while the second one tests the protocol in a real uncontrolled network. To achieve that, a test-bed is proposed and implemented that emulates the network impairments encountered in real-network such as packet loss, bit errors, and bandwidth limitation in a controlled manner. After that, QUIC is tested in real operational wired and wireless networks. In both scenarios, QUIC outperforms TCP in terms of delay, which strengthens QUIC position for being a potential alternative to TCP.

Published: April 2021

Abstract
The paper deals with calculation of overheating of a voltage instrument transformer used in medium voltage substations. Calculation of the primary and secondary windings is compared with measured values. These values are evaluated according to IEC 618691:2007, IEC 61869-3:2011 and IEC 60085:2007. In evaluation we focused on the state 1.9 × nominal voltage and thermal limiting output state. The article also compares the results for various parameters of instrument transformers that are necessary for clarification of calculation.
Meta-analysis of studies on the acquisition of receptive skills and vocabulary in CLIL
Authors: Cimermanová Ivana 
Published: April 2021

Abstract
Content and language integrated learning (CLIL) is a major area of interest within the field of formal education. There are numerous studies presenting data and results of CLIL implementation. The positive impacts have been reported in building positive attitudes to language learning, to content subject learning, increasing efficacy of language learning. Questions have been raised about the factors that (may) affect research results and their interpretation. Many small studies bring statistically non-significant data as they use small convenience samples. Meta-analyses enable the researchers to synthesise data from research with the same characteristics. The present article analyses the studies that focus on CLIL implementation at primary and secondary schools with special focus on receptive skills and vocabulary gains. Out of 385 selected studies were 9 included and applying randomised-effect model evaluated. The analysis found no statistically significant differences between the CLIL and EFL groups in listening and reading performance. Concerning vocabulary the statistically significant difference in favour of CLIL (p<0,0001) with overall estimate effect 0,84 and confidence interval ranging from 0,56 to 1,11 was observed.
Sociosemiotic Frontiers. Achievements, Challenges, and Prospects of Converging Semiotic and Social
Authors: Fomin Ivan 
Published: April 2021

Abstract
This article reviews the achievements and challenges that appear from attempts to integrate the studies of the semiotic and the social. Based on an analysis of the projects of Social Semiotics, semiotic sociology, and sociosemiotic approach to culture, it is suggested that the development of sociosemiotics could be represented (both retrospectively and prospectively) as trajectories of two frontiers. These are the frontier of sociosemiotic material and the frontier of sociosemiotic methodology. The frontier of sociosemiotic material represents how social semiotics progresses in broadening its scope by extending the set of materials which are considered as objects of sociosemiotic analysis. The frontier of sociosemiotic methodology describes how semiotic tools are integrated with other methodologies of social studies. The article shows what key steps have already been made to transcend the boundaries between social and semiotic research, and what directions are possible for further integration of social and semiotic sciences.
The lexicon of the “act of accepting (pratigraha)”: an approach to the multilayered Vedic culture
Authors: Candotti Maria Piera , Pontillo Tiziana 
Published: April 2021

Abstract
This joint work has its ground (and scope) in a variation-oriented reading of the Vedic sources, here applied to those which mention the act of the so-called “[gift-]acceptance” (pratigraha) within mechanisms for attaining and distributing the “goods of life” among all the members of a community. The most ancient occurrences are read and contrasted against the subsequent socio-ritual context where the well-known homonymous privilege and peculiar means of livelihood for Brahmans is depicted.
The tentative interpretation of the relevant passages and the consequent reconstruction of the several layers of the Vedic lexicon revolving around the verbal base prati-grah- might contribute to better assessing the presence of a specific Indo-Aryan cultural matrix that might have pre-existed (and co-existed with) the mainstream Vedic world, and to better understanding how later knowledge systems succeeded in creating a new all-encompassing balance.
Pulmonary Hypertension in Patients After Permanent Pacemaker Implantation
Authors: Yoncheva I.D. , Biserov D.E. , Negreva M.N. 
Published: April 2021

Abstract
Permanent pacemaker (PPM) implantation can lead to thromboembolic events at different times after the procedure. According to literature, 1.7% of patients with pulmonary embolism have an implantable cardiac device. This frequency is higher than reported so far, from 0.16 to 0.47% of the total population.
The pathophysiologic mechanism of pulmonary embolism in chronic thromboembolic pulmonary hypertension (CTEPH) is multifactorial. Recently, there is evidence that not only the organisation of thrombotic deposits in the proximal pulmonary arterial vessels is important, but also the development of small vessel disease, which plays an important role in the evolution and progression of the disease. The role of thrombosis in medical devices in contact with blood flow, such as stents, vascular grafts, heart valves, has been well studied and documented in scientific literature on biomaterials. It is clear that implantable cardiac devices such as pacemakers, similarly to other foreign surfaces exposed to blood flow, promote blood clotting and complement activation. Numerous studies to date have addressed the potential risk of distal vascular involvement of pulmonary circulation in the presence of a pacemaker, but none has conclusively proven this hypothesis.
Over the last decade, there has been significant progress in the therapeutic potential of CTEPH. Pulmonary endarterectomy remains the only therapeutic method that can lead to lasting clinical improvement in these patients while achieving a good quality of life. This method is operational, with high financial value and is associated with the presence of a highly specialised team of specialists. This justifies the search for ways to prevent the onset of the disease rather than treat the consequences.

Abstract
The performance group Landing was established in 2005 by 11 dance and performing artists, with an artistic vision to create site-specific dance projects. In 2008 Landing created an extensive site-specific project at the fully running St Olavs Hospital in Trondheim that was entitled Landing08. In this article we will share some of our experiences of this project. In 2010 Landing was reorganized into a production unit lead by us. Our aim is to initiate, produce, and support art projects that challenge target groups, sites and formats of presentation.
At arbejde med at begribe det fornemmede - en fortælling om et danseprojekt på et børnehjem i Rusland
Authors: Magven Anamet 
Published: April 2021

Abstract

Working with understanding the sensed: a narrative about a dance project at an orphanage in Russia is a paper based on a thesis for the postgraduate program Dance Partnership and Pedagogy at the National School of Contemporary Dance in Denmark (2008–10). The project was initiated by the partnership between the School of Contemporary Dance and the Greenhouse Project (Zelyonyi Dom) at the Orphanage # 9 in St. Petersburg, Russia. Zelyonyi Dom is a dance development project including 20 children from 8 to 12 years of age. A group of 9 children participated in the educational-dance-performance project discussed in this paper. The ten-day project was carried out in March 2010. The performance Petrushka premiered at the Fairytale Theatre in St. Petersburg. It was the first time the participating children performed on a real stage and they did so for a sold out 400 seat theatre. The project works with creative dance that approaches dancing, teaching and researching from a phenomenological perspective. It adopts a holistic view on the body, the psyche and the world and attempts to encounter the phenomena openly by suspending pre-made assumptions. The research explores moments of learning using the concept of attunement (“stemthed”) as it has been developed by Kirsten Fink-Jensen (1998). What is sensed in the dance space with the children, and how can one describe the sensed and nonverbal in words?
Particularities of media systems in the West Nordic countries

Published: April 2021

Abstract
This study compares the media systems of the West Nordic countries, namely the Faroe Islands, Greenland, and Iceland. All three countries are democratic welfare states with considerable institutional transfer from the larger Nordic countries. It is argued that the West Nordic media systems fit into the “Nordic model” when it comes to the perception of media as cultural institutions as well as the central role of public service media. On the other hand, the micro-size of the media systems in the West Nordic countries makes them vulnerable, and makes editorial independence more difficult compared with their larger Nordic neighbours. In particular, media outlets within these micro-size media systems seem more susceptible to clientelism, and journalists seem more inclined towards self-censorship. This article highlights how interplay between small size and distinct local factors shape the media system in each of the West Nordic countries.
Current aspects of polycystic ovary syndrome II: treatment of hyperandrogenism, insulin resistance and infertility
Authors: Zoltán Kun Imre , Ildikó Kun , Melinda Kolcsár 
Published: April 2021

Abstract
This work is a continuation of an earlier article published in this journal (no. 91/1: “Current aspects of polycystic ovary syndrome I: definition, pathophysiology, clinical manifestations, diagnosis and complications”). As the pathology of polycystic ovary syndrome is not fully known, the treatments used do not constitute a causal therapy, only pathogenetical interventions to break the vicious circles of pathological events. It does not currently have a universal therapeutic procedure or an approved specific drug. Treatment may be aimed at reducing hyperandrogenism, inducing ovulation and preventing complications. The patient’s complaints and desire for becoming pregnant should also be taken into account. In mild cases, an appropriate lifestyle (prevention/treatment of obesity) is sufficient, i.e. a 5-10% reduction in body weight can already result in significant improvement and also serves to prevent late complications (diabetes, hypertension, cardiovascular disease, hyperlipidemia). Oral contraceptives and antiandrogens are mainly used to treat hyperandrogenism (hirsutism, acne, and alopecia). A contraceptive whose progestogen component has antiandrogenic properties, or at least is androgen-neutral, is preferred, such as third-generation contraceptives. However, combined contraceptives (containing gestodene, desogestrel, drospirenone and cyproterone acetate) may increase the risk of venous thromboembolism and are therefore contraindicated in case of hypercoagulability. Antiandrogens (cyproterone acetate, spironolactone, finasteride, etc.) can also be used independently, but only with effective contraception (as these can cause feminization of the male fetus). Insulin resistance plays a crucial role in the development of this disease. Metformin is used as primary therapy, as it also has many other beneficial effects (e.g. cardiovascular and anti-cancer) described in recent years. These pleiotropic effects and their subtle mechanisms are discussed in detail. We highlight the possibilities of avoiding side effects and the current interpretation of rare contraindications (acidosis, hypoxic conditions, renal damage). Insulin resistance lowering agents include thiazolidinediones, acarbose, GLP-1 agonists, vitamin D, resveratrol, octreotide, but the beneficial effects of myoinositol and D-chiro-inositol are also mentioned. In the last part of the paper, the treatment options for infertility are discussed, highlighting the efficacy of clomiphene citrate, gonadotropins (“step-up”, “step- down” methods), IVF techniques, and ovarian drilling used for ovulation induction. We detail the importance and possibilities of the prevention of ovarian hyperstimulation syndrome and multiple pregnancies.
Where Law and Digital Health Care Meet…

Published: April 2021

Abstract
The modern information and communication tools and technologies of the 21st century open up new opportunities for patients and healthcare providers, thus contributing to human health, reducing the number of morbidities and premature deaths.
The application of modern technology in healthcare has resulted in a number of positive changes, but it has also been subject to multiple challenges, including legal dilemmas in this area: e.g. data management, data security and data protection, access to eHealth, etc.
After a brief introduction to the legal history of healthcare and the presentation of key statistics related to the current digital situation, the main objective of the present work is to analyze the relationship between health digitalization and law.
One of the key issues for successful healing in all historical eras is the legal protection and respect of patients and healthcare workers in the face of changes in the modern world. For this reason, it is important to address this unusual dimension of health care.
Study of factors affecting the performance of construction projects in AEC industry
Authors: Dixit Saurav 
Published: April 2021

Abstract
A construction project is like a living entity and requires the interconnection and coordination of several stakeholders and many of them have their objectives, which sometimes create a conflict of interest between the teams and within the teams. The success of any project is repeatable, and a set of attributes for the success of a construction project can be identified, requiring discipline and hard work. The construction sector is the engine of growth for a nation and supplies services and goods to other industries. The objective of the study is to analyse the enabling factors affecting the performance construction projects in Architecture Engineering and Construction industry. The methodology chosen for the study is to collect primary data from the Indian construction industry using structured questionnaire surveys. The collected data are analysed using reliability and factor analyses. The findings of the study provide the value of reliability, that is, Cronbach's alpha value of (0.86) of the data collected using a questionnaire survey. Furthermore, exploratory factor analysis produced five main significant factors based on covariance between the attributes and grouped into factors such as site management and coordination, leadership and financial management, planning, commitment, and coordination having a variance of 17.65, 11.8, 9.1, 8.5, and 7.5%, respectively. This article is the extended version of the paper accepted and presented at CCC2019.
Virtues – Moral Mirrors of Contemporary Society
Authors: Medved Ivana Ivančić 
Published: April 2021

Abstract
The aspiration for the ideal of a harmonious life assumes the systematic work on one’s own education of the soul and authenticity. Contemporary thoughts face us with a crisis of moral values. We ask the question if that crisis is reflected only on a social level, or must we observe and investigate the problem in the personal influence and responsibility towards society. This train of thought also forces the famous expression – quality of life – on us, which is considered a subjective indicator of satisfaction, i.e. dissatisfaction with the life of an individual in the evaluation of success when achieving personal needs and desires. Therefore, we will attempt to show what makes the ideal of a good life in this paper through the interpretation of the values in the work of Marcus Aurelius or, as the Stoics called it – the science of a virtuous life, and also the achievement of a positive subjective evaluation of the quality of life and satisfaction.

Published: April 2021

Abstract
Today, the importance of ecological education is often highlighted, although the current National Curriculum for Early and Preschool Education doesn’t even mention it. Although ecological education is not mentioned in this baseline document, various activities in this direction are often carried out in our kindergartens. An example of this is the play The Ecological Story by the author Sanja Seferović-Bosak from her collection of plays Maštarije: Igrokazi za djecu od 3 do 13 godina (eng. Pipe Dreams: Plays for Children of 3-13 years). This paper describes the preparation and performance of this play in 2017 in the kindergarten Radost (eng. Joy) in Novska. The theoretical part of the paper considers the basic settings of ecological education in early and preschool age, with special reference to current practice in Croatian kindergartens. The empirical part of the paper describes the stages of preparation and performance of the play The Ecological Story, with special reference to the compliance of this project with the requirements of the National Curriculum in terms of developing key competences for lifelong learning. The paper also contains an analysis of methodological procedures with particular reference to the preparation of musical numbers in the play.

Published: April 2021

Abstract

Introduction. The multitude of changes taking place in the female body in terms of the physiological aspect as well as in the psychological well-being in the perinatal period has become the motivation to find an answer to the question: what is the women’s satisfaction with life (SWL) after childbirth.

Aim. The aim of the study was to analyse the level of SWL among women after vaginal delivery and caesarian section according to selected socio-demographic characteristics.

Material and methods. The study included 128 females after vaginal delivery (n=58) and caesarian section (n=70) hospitalized at the maternity units in Lublin. The study was voluntary and anonymous. It was conducted in 2020 with the use of survey method and utilized two research tools: the Satisfaction With Life Scale (SWLS) and a questionnaire designed by the author in order to collect socio-demographic data.

Results. The mean SWL were 26.12±4.78 in women after vaginal delivery and 24.60±6.17 after cesarean section. Selected socio-demographic factors (age, education, marital status, place of residence, professional status) are significantly related to the satisfaction with life of women after cesarean section; while the material situation and living together with the family among women with vaginal delivery.

Conclusions. Analysis of the results obtained indicated that actions aimed at the improvement of SWL should be directed to young, unemployed, with primary and vocational education, unmarried women and with poor financial situation.

Abstract
Intensity-modulated radiotherapy (IMRT) is being practiced for the last several years with a special approach for radiation therapy in post-mastectomy breast cancer patients. Meeting the cardiac dose constraints has always been a challenge during radiotherapy planning by both IMRT and VMAT (volumetric modulated arc therapy) of post-mastectomy left breast patients. With the advancement in IMRT planning techniques, it has been modified to VMAT with more degrees of freedom for modulation and is being utilised more frequently. This helps in obtaining a suitable plan for achieving both the dose homogeneity in target volume and dose constraints to Organ at Risk (OAR). 10 Patients with carcinoma of the left breast (post-mastectomy) were selected for this study. VMAT treatment plans for these patients were generated for 6 MV photons on the Monaco treatment planning system (TPS) using two types of optimization modes i.e. Pareto and Constrained mode available in Monaco TPS. For comparative dosimetric evaluation of the efficacy of these two types of optimization modes similar calculation algorithms, calculation grids, arcs, and beam sequencing parameters were used for generating treatment plans. The dosimetric quantities such as volume receiving more than 95% of the prescribed dose (V95), volume receiving more than 107% of the prescribed dose (V107) and Maximum dose (Dmax) for target volume, mean dose (Dmean) for heart, volume receiving more than 30 Gy (V30) volume receiving more than 20 Gy (V20) volume receiving more than 5 Gy (V5) for ipsilateral lung and total monitor units delivered were analysed for both optimization modes. A judicious mix of multiple planning parameters and variables using these two modes of optimization was applied and recorded. Both optimization modes yielded similar outcomes. However, Pareto mode has shown better coverage for planning target volume (PTV) with comparable doses to OARs.
