Abstract
The aim of the work was to study the agglutination and hemolysis of erythrocytes under diff erent conditions in vitro in a patient with unknown cause of anemia and concomitant secondary instability of endoprosthesis.

Material and methods. One percent (1%) suspension of erythrocytes of a woman, 61 years old, A (II) Rh- (negative) presented with anemia was incubated with her serum and plasma at pH 7.3, pH 5.8 and 9.0, as well as with IgM α and β antibodies. Unithiol was used to destroy IgM antibodies. The samples were incubated for 12 hours at 37° C, and the presence of the agglutination and hemolysis was evaluated.

Results. The incubation of the plasma with unwashed erythrocytes of the patient led to the agglutination of the erythrocytes and the usage of the complement led to the hemolysis. After inactivation of IgM in the plasma the agglutination was absent and the hemolysis was present under usual conditions and at pH 5.8, whereas at pH 8.0 the hemolysis was attenuated, however a slight degree agglutination appeared. The usage of the complement led to the agglutination and the hemolysis, absent at pH 8.0. The plasma incubated with washed red blood cells and the complement led to the hemolysis. The incubation of the serum with washed erythrocytes led to the hemolysis at pH 5.8, attenuated after the usage of the complement. The contact of terbinophine with plasma and unwashed red blood cells led to the absence of both the hemolysis and the agglutination. Candida lusitaniae growth was detected in the plasma.

Conclusions. The agglutination of unwashed erythrocytes by own plasma, attenuated in the alkaline medium and enhanced in the acid medium, as well as the absence of the agglutination after the usage of terbinophine and the hemolysis in the presence of the complement might be the signs of mycogenic and autoimmune origin of anemia with the activation of autoimmune complement – binding antibodies.

Published: May 2020

Abstract
The esophageal diverticula are divided into pharyngoesophageal, parabronchial and epiphrenic. They could also be divided into congenital and acquired, true and false, pulsion and traction. Pulsion diverticula are usually formed in motor disorders of the esophagus, above the place of hypertension and uncoordinated peristalsis. They are pseudo-diverticula caused by increased intramural pressure, leading to herniation of the mucosa and submucosa through the focal areas of the esophageal wall. We present a 65-year-old woman who underwent left-sided transthoracic diverticulectomy, modified Heller esophagocardiomyotomy, and modified Belsey-Mark IV fundoplication due to a huge epiphrenic esophageal diverticulum.

Abstract
Cutaneous xanthogranuloma is a rare benign tumor and both adults and children could be affected. Head and neck area of the human body is the most commonly affected one which often poses a serious reconstructive challenge for the plastic surgeon who is in charge of removing the lesion. We report on a clinical case of an adult female patient who presented with cutaneous xanthogranuloma of the upper lip, involving the subnasal area. Both diagnosis and surgical treatment were difficult, considering the clinical behavior and location of the tumor. An innovative surgical approach going out of the dogmas of plastic surgery was applied and an excellent result was achieved.

Authors: Vasileva B. , Vodenicharova Al. 
Published: May 2020

Abstract
A vital aspect of the medical activity on which the medical care quality directly depends has been the doctor-patient relationship; it is of complex nature and is formed by a number of factors: professional ethics, communication culture of the doctor, the patients’ confidence in the doctor, etc. From an ethical point of view, the confidence of the patient has been an ethical indicator and criterion of particular importance for the quality and interpersonal relationship between the doctor and the patient. Data from the overview of a number of papers, as well as data from our own empirical study, has indicated the presence of a number of unresolved problems in this relationship. That has raised the significant necessity of a more thorough and comprehensive training of the medical staffin professional medical ethics in undergraduate and postgraduate training.

Authors: Gençoğlu Muharrem Tuncay , Agarwal Praveen 
Published: May 2020

Abstract
Emerging as a new field, quantum computation has reinvented the fundamentals of Computer Science and knowledge theory in a manner consistent with quantum physics. The fact that quantum computation has superior features and new events than classical computation provides benefits in proving mathematical theories. With advances in technology, the nonlinear partial differential equations are used in almost every area, and many difficulties have been overcome by the solutions of these equations. In particular, the complex solutions of KdV and Burgers equations have been shown to be used in modeling a simple turbulence flow. In this study, Burger-like equation with complex solutions is defined in Hilbert space and solved with an example. In addition, these solutions were analyzed. Thanks to the Quantum Burgers-Like equation, the nonlinear differential equation is solved by linearizing. The pattern changes of time made the result linear. This means that the Quantum Burgers-Like equation can be used to smoothen the sonic processing.

Published: May 2020

Abstract
In recent years, a rapid increase in the use of three-dimensional (3D) printing technologies in medicine, especially in the manufacturing of the diagnostic models, can be observed. In some cases, there is a need to fabricate transparent models that allow visualization of internal structures of the object. Unfortunately, techniques used to manufacture such models are often very expensive and time-consuming. The above-mentioned issues were the motivation for developing a new method of fabrication transparent models for visualization of internal structures for planning surgical treatments. This paper presents the process of making transparent models using the newly developed method – the stacked layers method. In order to compare this new method and one of the most common 3D printing technologies – fused deposition modeling (FDM) – the models for two medical cases using both of these methods were fabricated. As a result of this work, it can be concluded that the stacked layers method provides faster and cheaper way of making transparent medical models. The main features of fabrication process that have a huge impact on quality of the models made by new method were pointed. The results of this study suggest that models fabricated with the use of this method can be useful as a diagnostic tool in medical applications for planning surgical treatments.
Settlement Compactness as a Quality Characteristic of Land Use
Authors: Smilka Vladyslav 
Published: May 2020

Abstract
The aim of the research is to propose the method for forming an indicator of compactness of a populated population and to test it. The comparative analysis, structuring, geospatial modelling methods have been used in the research. Land use management and development regulation, which is carried out by urban planning documentation, is the spatial frame for sustainable territory development. Forming of quantitative and qualitative indicator system that characterises the level of urban development of a settlement is an overriding issue for state estimation of settlement development. Management decisions on land use management should be made taking into account the evaluation results. The compact form is an essential basis for the efficient and stable use of the settlement territorial resources. There is no single evaluation technique of settlement compactness; there are a variety of approaches and methods for the assessment of settlement form. The compactness level in this study is estimated by a system of indicators that attests to the multiplicity of land uses and the degree of accessibility to basic services and leisure facilities. The determining technique of component compactness has been tested in evaluating the planning structure of Kyiv. All planning quarters are rated according to a five-level rating scale. For each classification group, general recommendations have been developed to improve the land use system aimed at improving the compactness of the settlement. The results of compactness assessment can be used through geoinformation monitoring tools in the provision of administrative services as justification for managerial decision-making.

Internal Service Quality at our University - Centralizing vs. Decentralizing
Authors: Krause Regina , Berg Marco , Domröse Hartmut 
Published: May 2020

Abstract
This article looks at interdisciplinary services such as a career service center and start-up counselling for students. Using the example of the Wismar University of Applied Sciences, the question is examined as to whether it makes more sense for the students of the university to bundle these services in a central unit or whether it would be better to allocate them to faculties or departments on a subject- specific basis. The advantages and disadvantages of both solutions are discussed. In the concrete case of the Wismar University of Applied Sciences, it is shown that based on almost a decade of experience with its approach, the centralisation of these interdisciplinary functions has indeed led to synergies. The article also identifies a set of critical success factors which the design of such a solution will need to meet.

Published: May 2020

Abstract
The existing Master programs in Ukraine are based on separate branches of transport systems. The general approach used was to isolate and hence to study the single elements and to neglect the relationships between them within the whole analysis systems. Therefore, the developed educational modules, based on smart technology and environment (which exploit these neglected relationships) have not yet presented in the current curricula of Ukrainian Master programmes in transport systems. In this context, the paper presents the upgrading process of Master curriculum, designed and implemented in O.M. Beketov National University within the E+-KA2-CHBE Programme. In particular, how the local conditions and needs as well as the results of the international reviews on which the curricula were built are described. Finally, some indications for process transferability are provided.

A Critical Reflection on Relationship between ICT and Change Management in Enhancing Teaching and Learning Performances
Authors: Som Ratana , Dumitrascu Danut 
Published: May 2020

Abstract
Numerous studies have pointed out direct positive impacts of Information Communication Technology (ICT) on education quality. From just tool, ICT is being viewed in itself as quality or as catalyst for quality improvement. These findings have led universities worldwide to adopt ICT regardless of uncertainties. Consequently, not all of them succeeded. Proofs from cases around the world show that ICT produces positive impact only in the environment that fits. Such environment is fostered by an effective change management approach. The main aim of this paper is therefore to present the symbiotic relationship between ICT and change management, zeroing on how changes are managed to attain a proper ICT ecosystem for education quality improvement. It also aims to understand, through the conducts of extensive bibliographical research, along with critical content analyses, the roles of ICT in education, its design and impacts, and what constitutes effective change management approach for ICT inclusion. Key findings include: that the integration of ICT alone does not necessarily produce direct positive impact on teaching and learning, but its design; that a good design requires a proper change management process, driven by ICT, and that the involvement of all stakeholders, particularly functional managers, is critical to attain better performances.

Authors: Harmoinen Sari , Koivu Katri , Pääsky Leena 
Published: May 2020

Abstract
In this study, the authors analyze how students from the University of Oulu (N=1585) reflect on their possibilities to affect climate matters through social activity. The data was collected with an online survey in the autumn of 2019 and was analyzed with quantitative and qualitative methods. Readiness for climate actions in social activity was moderately low and lower than in other climate actions considered in the survey. The following categories were identified to explain readiness for social activity: Emotional Expressions, Trustworthy Information, Individual Freedom, Societal Responsibility, and Us Against the World-mindset. Some of the possibilities for climate actions suggested by students include developing and exporting Finnish innovations and expertise, leading by example, receiving and distributing reliable information, making decisions and regulations on a societal level, providing economical support for environmental organizations, and affecting personal actions.
Sustainable Use of Ecological Concepts in Educational Science
Authors: Svenkerud Sigrun Wessel , Madsen Janne , Ballangrud Brit Bolken , Strande Anne-Lise , Stenshorne Elisabeth 
Published: May 2020

Abstract
In this article, the authors discuss the use of ecological concepts (ecology, boundary, niche) in educational research to understand if and how these concepts from one field of science (ecology) can bring a new understanding to another field of science (education). We have conducted a systematic search in the ERIC database to identify articles where key concepts from ecology, such as ecosystem, boundaries and niche, are used in educational research. An algorithm inspired by Rodger’s (2000) contextual model of concept analysis was used to examine how the concepts contribute to explore, explain or understand an educational system or an educational process. We find that the use of ecology-oriented concepts is related to a circular rather than a linear causality between actors and environment and between thoughts and actions. Thus, an ecological educational approach is characterised by wholeness, and emphasizes context as well as the complex interconnected mechanisms in educational processes.

Published: May 2020

Abstract
The aim of the study was to determine the effectiveness of leachates from municipal landfill co-treatment with the dairy wastewater in an aerobic membrane bioreactor. It was working in MSBR (sequential membrane bioreactor) systems twice daily and was equipped with the immersed membrane module installed inside what enabled its back-washing performance. The system was working. The concentration of activated sludge in the membrane bioreactor was equal to 4.0 g/dm3. However, the sludge load was at the level of 0.06 g COD/(g d.m. · d). The oxygen concentration was at the level of 3.0 g O2/m3. The share of leachate was varied in a range of 5 to 15 % vol. The evaluation of the effectiveness of the treatment process was based on the change of parameters characterizing the crude sewage and treated sewage. All analysis was carried out according to standards. Following parameters were determined: COD, BOD5, TOC and concentrations of phosphate phosphorus, total nitrogen and ammonium nitrogen. Chemical analysis is often not enough to define the degree of wastewater treatment. It was used toxicological research to determine the effect on the environment. Toxicity of wastewaters was measured using biotests with Vibrio fischeri and Daphnia magna. The results revealed that the volume of leachate in the treated mixture should not exceed 10 % vol. The following conclusion can be drawn from the present research - co-treated wastewater was not toxic. Landfill co-treatment with the dairy wastewater impacts on the effectiveness of biological wastewater treatment. Leachate includes substances which have low susceptibility to biodegradation; on the other hand, dairy wastewaters provide a lot of organic compounds, which can help to treat them.
