Published: October 2020

Abstract
Introduction: Edentation is a major emergency and has an echo over the entire stomatognathic system. The treatment of partial edentation has undergone major changes in the last decades for multiple causes, including increasing the level of dental, medical education, introducing new techniques, methods, and materials, increasing the duration of retention of teeth on the arch.
Aim of the study: The aim of this study is to determine the degree of satisfaction of patients with a fixed prosthetic denture, to highlight the importance of communication between doctor and patient with repercussions on the results of prosthetic treatment, and evaluate the degree of awareness of oral health and oral hygiene practices.
Material and Method: For this study it was used a self-designed questionnaire, which explored both clinical and non-clinical dental services. The questionnaire consisted of three parts: first part (A) includes socio-demographic indices, part two (B) includes questions related to the doctor-patient relationship, and in the third part (C) the questionnaire asks questions regarding the general satisfaction of the patients with reference to the prosthetic tratament. The questionnaire also includes the material (s) from which the prosthetic denture is performed and the area of the edentation.
Results: The present study was performed on a batch of 117 people, 48 female, and 69 males between the ages of 21 and 60. Our results show that the majority of patients present metallic-ceramic dentures, located in most cases in the lateral area, and the majority of patients are satisfied with the prosthetic tratament. There were no patients complaining about the result of the tratament. Pacients are delighted by their relationship with medical staff.
Conclusions: The most important finding of this study states that a large proportion of patients showed a lack of knowledge regarding oral hygiene measures and the importance of maintaining a fixed prosthetic denture using a dental abutment. Also, the majority of the doctors did not pay attention to the post-treatment instructions regarding the maintenance of a fixed prosthetic denture.

Abstract
In the etiology of periodontal disease, dental caries act as a favoring factor. The purpose of our study was to evaluate the role of untreated or incorrectly treated carious lesions in the occurrence of pathological changes in the periodontal support. Material and methods: In order to evaluate the impact of the dental caries in the appearance of destructive lesions at the periodontal level, we examined 378 X-rays. The radiographies were selected based on the presence of approximal dental cavities, untreated or incorrectly treated and we appreciated the association of these factors with the presence and the level of bone resorption of the interdental septum. Results: On the 378 radiographies we examined, it was discovered the presence of 398 approximal carious lesions, of which 146 were associated with bone resorption. The examined radiographies permitted us to evaluate 1512 fillings inserted in second class cavities, of which 1103 were correctly done, and 309 were incorrect and associated with bone resorption phenomena. Incorrectly done restorations were associated with bone resorption phenomena due to the lack of contact with the adjacent tooth for 213 of these, and because of an inaccurate adaptation at the level of the gingival threshold for 96. Conclusions: The dentist has to pay a special attention to the approximal coronary restorations because these can favor the retention of bacterial plaque and, in most cases, can lead to bone loos in the alveolar ridge area.
Comparative study of the comfort in patients rehabilitated with three types of partial dentures
Authors: Bechir Farah , Suciu Ilinca 
Published: October 2020

Abstract
Introduction: At present, the researchers are targeted to improve and increase the biocompatibility of dental materials that are in direct contact with biological tissues. The biocompatibility of the dental materials that contact the tissues of the oral cavity present relevance for the patient, clinician, dental technician, and manufacturer.
Aim of the study: The aim of this study was represented by the comparative research regarding the comfort of the patients wearing removable partial prostheses with clasps made of wire and flexible polymers.
Material and Methods. Patients wearing partial dentures from Meliodent heat-cured acrylic resins with wipla wire clasps, flexible partial dentures made from Valplast and dentures with clasps of CuSil silicone rubber participated in this study. The research was performed on 3 groups, of 8 patients each, in which comfort levels (according to 5 criteria) were determined, after 6, 12, 18, respectively 24 months of the partial removable prostheses insertion in the oral cavity.
Results. Presence of decubitus lesions of the oral mucosa in the clasps areas was noticed mostly in the Valplast polyamide dentures (37.5%), existence of color changes at the base of prostheses and of clasps area appeared in 37.5% of the third group (CuSil PAD) patients, no patient included in the study presented allergic reactions and at the third and fourth recall, only 1 patient of all groups complained of unpleasant taste in the oral cavity.
Conclusion. The removable prosthetic restorations with clasps made of flexible polymers and CuSil gaskets of silicone rubber, although initially much more comfortable and therefore much better accepted by patients, after two years were no longer active, could not be activated and necessited technical restorations, compared to those made of wipla wire clasps, which were activated with pliers, or, in the case of fracture, were replaced by the technician in the dental laboratory.
Fatigue Degradation of the Ram-Air Parachute Canopy Structure
Authors: Szafran Krzysztof Stanisław , Kramarski Ireneusz 
Published: October 2020

Abstract
In this work, the authors continue researching issues related to fatigue of aircraft structures made of fabrics. Parachute systems are widely used in military, sport and recreational aviation. Braking parachutes as well as skydiving and troop parachutes are characterized by the repeated use of parachute canopies, which are exposed to wear and fatigue. Until now, parachutes were difficult to design aviation systems due to their complex and unsteady opening characteristics, large changes in the geometry of canopies, suspension lines and tape risers as well as exposure to stochastic atmospheric turbulence. The fatigue of the canopy fabric, suspension lines and tape risers is a problem that must be addressed by textile designers and designers of reusable parachute systems. The authors of this work demonstrate the complexity of operating a parachute in hard multiple use conditions and propose ways to extend the parachute’s service life without compromising safety.
Monetary Policy after the Great Moderation
Authors: Peña Guillermo 
Published: October 2020

Abstract
The interferences among some financial, economic and monetary variables are checked as an indicator of economic performance in the long run and for the monetary policy applied between the Great Moderation (GM) of 1987-2001 and the Global Financial Crisis of 2007-2009. For achieving this target, some Granger causality tests are applied to GDP growth, credit growth, and lending interest of 36 countries of the EU and the OECD for the full sample of 1987-2012 and the sub-sample of 2002-2007. Results corroborate the interferences among these variables for the discretionary monetary policy applied immediately after the GM, within the “Ad Hoc Era” or “lax period”, and independence when monetary policy was correctly applied and rules-based.
Financial System Stability, the Timing of Climate Change Action and the Federal Reserve
Authors: Schellhorn Carolin 
Published: October 2020

Abstract
Timely and effective climate action is a precondition for the stability of the global financial system and for long-term, inclusive prosperity. Because the Federal Reserve and other central banks share responsibility with legislative and regulatory authorities and other experts for maintaining financial system stability, the Fed also shares responsibility for effective climate action. For climate action to be effective in reducing greenhouse gas emissions and limiting global warming, it must be widespread, it must be substantive, and it must come sooner rather than later. The new low-interest rate monetary policy environment favors sustainable long-term, but also high-risk, investments. Market participants need timely guidance and support from regulatory and supervisory authorities, including the Federal Reserve, in order to expedite global fund allocations to low-carbon assets.

Published: October 2020

Abstract
The main goal of our study is to theoretically and empirically contribute to the analysis of relation between institutional features and R&D in business enterprise sector and consequently on sustainable economic growth. We exploited the available measures of institutional quality from World Government Indicators of World Bank and data on R&D in business enterprise sector. We employed First-Differencing GMM method to estimate the model on the balanced panel data including the following European countries: Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, Serbia and the Slovak Republic, for the time span of 2007-2017. The institutional features are statistically significant factor of R&D in business enterprise sector. We found that Government effectiveness and Control of corruption in particular are very important in supporting the R&D. These measures of institutional quality are key institutional determinants of R&D in business enterprise sector. R&D in business enterprise sector is one of the crucial parts of the overall R&D, and therefore policymakers have to develop favourable conditions for those activities in private firms. Institutional features should be an important variable in explanation of R&D intensity. The presented analysis empirically contributes to the body of knowledge on determinants of R&D for European countries that have to develop their institutions further in order to grow sustainably. This study is using contemporary methods for testing the underlying problem.
The Relationship between Inflation and Interest Rates in the UK: The Nonlinear ARDL Approach
Authors: Gocer Ismet , Ongan Serdar 
Published: October 2020

Abstract
This study reconsiders the Fisher effect for the UK from a different methodological perspective. To this aim, the nonlinear ARDL model recently developed by Shin et al. (2014), is applied over the periods of 1995M1-2008M9 and 2008M10-2018M1. This model decomposes the changes in original inflation series as two new series: increases and decreases in inflation rates. Hence, it enables us to examine the Fisher effect in terms of increases and decreases in inflation separately. The empirical findings support asymmetrically partial Fisher effects for the UK in the long-run only for the first period. Additionally, this study attempts to describe and introduce a different version of the partial effect concept for the first time for the UK.
GARCH Modelling of High-Capitalization Cryptocurrencies’ Impacts During Bearish Markets
Authors: Panagiotis Anastasiadis , Efthymios Katsaros , Anastasios-Taxiarchis Koutsioukis , Athanasios Pandazis 
Published: October 2020

Abstract
This study investigates how twelve cryptocurrencies with large capitalization get influenced by the three cryptocurrencies with the largest market capitalization (Bitcoin, Ethereum, and Ripple). Twenty alternative specifications of ARCH, GARCH as well as DCC-GARCH are employed. Daily data covers the period from 1 January 1 2018 to 16 September 2018, representing the intense bearish cryptocurrency market. Empirical outcomes reveal that volatility among digital currencies is not best described by the same specification but varies according to the currency. It is evident that most cryptocurrencies have a positive relationship with Bitcoin, Ethereum and Ripple, therefore, there is no great possibility of hedging for crypto-currency portfolio managers and investors in distressed times.
Monetary Base Controllability after an Exit from Quantitative Easing
Authors: Tanaka Atsushi 
Published: October 2020

Abstract
This study examines the problem that a central bank may face after exiting a monetary quantitative easing policy. It develops a simple dynamic optimization model of a central bank, which finds that if the bank needs to absorb a substantial amount of excess reserves when exiting, the monetary base may become uncontrollable. In this case, the bank has no option but to increase the monetary base by more than the target amount, which leads to an undesirable money supply expansion and, ultimately, to inflation pressures. The model shows the condition when a central bank faces such a challenging situation.
Thermal Structure of Water During the Summer in Lakes of the Polish Lowlands as a Result of their Varied Morphometry
Authors: Skowron Rajmund 
Published: October 2020

Abstract
The paper discusses the impact of lake morphometric parameters on the thermal structure of water during the period of summer stagnation. The summer period in the lakes is characterized by clearly expressed properties of the thermal structure of water, differentiating lakes from one another. The study was carried out on 141 lakes in northern Poland, for which at least 3 vertical water temperature measurements were taken in different years. They showed a significant influence of lake basin morphometry upon the thermal structure of water in lakes. In general, measurements of the vertical distribution of water temperature showed clear diversity, and depending on the depth also thermal layers (epi-, meta- and hypolimnion). The results of the analysis of 8 lake morphometric parameters and 10 thermal stratification parameters revealed the existence of significant dependencies between them. The best-preserved relations (statistically significant) occurred between the parameters characterizing the lake depth and meta- and hypolimnion properties, as well as the thermal stratification factor and heat content in a unit of volume.
Pedagogy and Education against the Collision of Ethoses
Authors: Kwieciński Zbigniew 
Published: October 2020

Summary
The essay proposes a way to search for common educational goals in a situation marked by deep political and worldview-related divisions in Polish society. It recalls Kazimierz Sośnicki’s concept of the “collision of ethoses” conceived in the 1930s, and the need to overcome shallow ‘ceremonialism’ in order to move towards a deeper experience of values, both spiritually and through altruistic actions.
Education for Humanity – as the Message of the Older Generation of Teachers – In the Light of their Memoirs 2016
Authors: Dróżka Wanda 
Published: October 2020

Summary
The article attempts to familiarise the reader with the memoirs of teachers compiled as a result of the third edition of the National Competition for memoirs and other autobiographical statements under the title “Teacher’s message: Generations of Polish Teachers for the Future” (2014–2016). In the light of the preliminary analysis of the texts submitted, an outline emerges of the mission that teachers would see for themselves, for their successors, and for education of the 21st century. It is something significant: the mission of protecting humanity for future generations, for preserving the world, for the survival of spiritual values confronted with consumerism, cybertechnology, and scientific progress on the basis of genetics, computer science, etc. Education appears in the light of these diaries as a space and a way to reinforce humanity, which is threatened from different sides. There are two approaches here, two concepts of education and training, and of the teacher’s role in this work, the more conservative and the more liberal. In general, it is a question of rational citizenship, the rational use of subjectivity and autonomy, which is similar to M. Nussbaum’s concept of remedying the citizenship crisis. This mission of education requires reflective, subjective and autonomous teachers, using discursive reflexivity (thinking about their own thinking), with an analytical attitude, respecting the requirement of interdependence, understanding the contemporary world, themselves and others. In turn, what this requires from teachers is deep knowledge, thorough education, a high level of culture, and humanistic, subjective and reflective changes in their education and professional development.
Women’s Academic Careers – Entanglements and Inspirations
Authors: Zaworska-Nikoniuk Dorota 
Published: October 2020

Summary
In the article “Women’s Academic Careers – Entanglements and Inspirations”, I write about the significant problem of the specificity of female careers related to gender and its stereotypical perception. The purpose of the research was to analyse the individual stages of women’s academic careers in the academic field of pedagogy (humanities and social sciences) in 2013–2019, based on the latest research reports (E. Kulczycki Report and the ‘Science in Poland’Report). The study uses data about pedagogy as a feminized discipline, in which the majority of academic staff are female. The main research question was: How do the individual stages of women’s academic careers in social sciences (especially pedagogy) progress, and what factors determine them? The research method used in this study was what is often referred to in colloquial language as “desk research”, i.e. reviewing and analysing scientific literature, analysing data sources, compiling them and mutual verification. The interpretative background of this research was an analysis of the mechanisms of gender inequalities at universities (related to the mechanisms of the labour market).

In recent years, increasing attention has been devoted to developing pedagogical approaches that are appropriate in heterogeneous classrooms. Teachers working in inclusive classrooms must develop forms of student work that do not isolate and stigmatize learners with special educational needs. In the first part of the article, the author analyzes the origin and essence of the idea of inclusive education. In the second part of the article, three forms of work organization for students in inclusion classes are characterized: Peer Tutoring, Cooperative Learning and Multi-level Teaching.
The Image of the Kindergarten Teacher in the Israeli Media
Authors: Alezra Fani 
Published: October 2020

SummaryRecognition of the importance of early childhood education is increasing. Many reports published in Israel and around the world deal with the powerful and critical impact of this era on individuals and society. In contrast, the professional image of the kindergarten teacher in Israel is seen as being as low-status as in many countries. This professional image influences the choice of teaching profession and the conditions of admission in teacher training colleges. The low-status image is influenced by many publications in the Israeli media. To say these publications are unflattering to the profession and to kindergarten teachers would be an understatement. In this article, I will try to answer the question: How is the kindergarten teacher’s image expressed in publications about kindergarten and kindergarten teachers in the media in Israel? The research tools are ten articles with the kindergarten tag on the news content sites Walla and Mako as of June 2019. The method chosen is content analysis, a research technique for objectively describing media content through which messages can be identified. In so doing, I will draw conclusions about what can be done to improve publications about the profession and at the same time to improve the image of the kindergarten teacher in society.
