The Impact of Digital Technologies on Neoclassical Labour Market
Authors: Petrová Kateřina 
Published: January 2023

AbstractLabour market economics works on the principle of a neoclassical approach. Competitive forces, corporate policy, collective bargaining, and state intervention create the reality of the market. Technological progress in advanced technology, robotics, and artificial intelligence is strengthening the economies of several countries. The article deals with the actual influence of digital technologies on the neoclassical paradigm of the labour market and the impacts on the tasks and requirements for the competencies of workers and the level of their qualifications. Research is based on secondary data from relevant sources with emphasis on the quality using the interface Primo database, enabling the search for data in full-fledged databases (Web of Science, ProQuest, etc.). The real minimum wage, employment rate and jobs at risk of automation were analysed to compare the situation in European countries. The main objective is to analyse the magnitude of the impact of digital technologies on the labour market. The results point to technological progress, especially automation, which eliminates job positions by substituting low-skilled workers with machine learning robots. Government can ensure more balanced inclusive growth in the area of education. The change in the concept of teaching leads to higher qualifications and skills for future employees.

Published: January 2023

Abstract
Waste transport is just one of the segments in the solid municipal waste management. Throughout the entire waste life cycle, starting by generation of waste, via storing, collecting, transporting, recycling, treating and depositing, several different polluting substances are emitted. The solid waste transport, apropos, transporting vehicles emit into the air different pollution substances such as CO2, CO, NOx, NMVOC, PM, PAHs etc. These substances can present certain problems for human health and environment. The research subject of this study is the analysis of solid waste transportation within the Banja Luka region (B&H), from towns and municipalities belonging to the region and transporting their mixed municipal waste to the Banja Luka landfill. In the analysis, following parameters are included: distance to the landfill, type of vehicle used for the waste transportation, type of the engine, vehicle capacity and the number of tours during a year. The study estimates the emission of CO, NOx, NMVOC, and PM2.5 during one year using the listed parameters and by applying EMEP/EEA guidelines for estimating the emission of polluting substances into the air. The largest emission of polluting substances (CO, NOx, NMVOC and PM2.5) is from the oldest vehicles. The newest vehicles had a significantly lesser emission of these polluting substances into the air. The recommendation for decreasing the emission from the transportation vehicles is to organise the transfer-stations, procure new vehicles, optimise the collection routes and decrease the number of tours, as well as to better the usage of the vehicle capacity level.

Abstract
As part of the routine control of the Tunisian network for the monitoring of the most problematic microalgae species Karenia selliformis and Alexandrium minutum and for the study of hydrophilic and lipophilic marine biotoxin profiles, clams and seawater samples from Boughrara lagoon were analysed during the past decade. The results showed that the abundance of Karenia selliformis and Alexandrium minutum in the Boughrara lagoon exhibited significant variability at annual scales. K. selliformis was recorded in all sampling years with interannual variability. Among the nine sampled years, 2010, 2012, 2016 and 2017 were, respectively, the most significant in terms of mean abundance (2.85, 2.42, 1.38, 1.69) ∙ 105 cells L–1. A. minutum species were observed in the water column during all investigated years except in 2013, 2016 and 2017, but in low concentrations compared to K. selliformis (≤ 7.4 ∙ 102 cells L–1). Using LC-FLD, traces of paralytic toxins (C1 and GTX-2) were detected in some clam samples. Their concentrations were largely below the regulatory limit. For the first time, N-sulfocarbamoyl gonyautoxin-2 (C-1) and gonyautoxin 2 (GTX-2) were detected in some clam samples from this region. LC-MS/MS analysis confirmed the presence of gymnodimines in some samples. The main peak corresponds to the GYM-A with high concentrations generally above 1 mg kg–1 of clams meat, which confirms the persistence of this neurotoxin in Boughrara lagoon.
Evaluating the impact of public financial support on innovation activities of European Union enterprises: Additionality approach
Authors: Lewandowska Małgorzata Stefania , Weresa Marzenna Anna , Rószkiewicz Małgorzata 
Published: January 2023

Abstract
The study aims at estimating the effects of support for research and development and innovation from the European Union (EU) budget for boosting innovation in European enterprises, using input, output, and behavioral additionality approach. The study is based on microdata of the Community Innovation Survey 2012–2014, covering a sample of 98,809 enterprises from 14 EU countries. The direct and indirect relationships between the variables were studied using path analysis. For the whole sample, three additionality dimensions were confirmed; however, the result differs across EU member states. Multi-additionality of EU grants was confirmed only for Spain; in eight EU countries, input and behavioral additionality were proved, and in two, only behavioral additionality was found. This leads to the conclusion that the potential of EU support is not fully exploited, in particular in Central and Eastern European countries, and there is room for improvements with regard to policy design and implementation.

Published: January 2023

Abstract
A variety of laboratory tests are used in the evaluation of the hepatic patients. Serum cholinesterase is reduced in liver disfunction in contrast with other enzymes. The aim of this study was to assess the value of serum cholinesterase in evaluation of the liver reserve function in cirrhotic patients. A total of 70 patients were divided into 3 groups according to the Child-Pugh Score. Using corelation analysis, the correlation between serum cholinesterase and albumin and serum plasma prothrombin time was analysed. Cirrhotic patients were grouped into A, B and C grades as per Child-Pugh score.
The results showed that cholinesterase levels tend to decrease according to the Child-Pugh score. The cholinesterase correlated with the albumin serum levels, value of Child-Pugh score and MELD-Na score and didn’t corelate to INR. In conclusion, correlated with the damage severity of the liver cells cholinesterase may respond to liver reserve function.

Abstract

Introduction. Chronic kidney disease (CKD) is one of the most prevalent public health problems of the elderly population. End-Stage Renal Disease (ESRD)’s most common treatment is dialysis. There are some dissimilarities between the sexes that are apparent in the status and the possible outcomes of CKD. This study aims to shed some light on these somewhat overlooked wwwvariations and their implications.

Materials and methods. We conducted an observational study on subjects with CKD, undergoing hemodialysis for at least 2 years. For participation, we selected an equal number of men and women, which were divided into 2 groups according to gender. Plasma levels of the following parameters were monitored: creatinine, urea, bicarbonate, phosphorus, calcium, alkaline phosphatase, vitamin D, FGF-23 and TNF-alpha. The differences of the variables between the two groups were evaluated using TTEST and CORREL test.

Results. A significant correlation was between the plasma levels of FGF-23 and gender (p =0.02). Regarding the plasmatic levels of urea, besides the expected difference in pre- and post- dialysis levels, we obtained a significant correlation between its post-dialysis value and gender (p =0.045). In regard to the plasmatic levels of the alkaline phosphatase, there was a significant correlation between its value and gender (p =0.01).

Conclusions. There is a significant correlation between the plasmatic levels of creatinine, urea, alkaline phosphatase, vitamin D, FGF-23 and gender. Women present lower levels of creatinine and urea, while men present lower plasmatic levels of vitamin D, alkaline phosphatase and FGF-23.

Abstract
Aortic stenosis is one of the most common valve diseases in patients over 60 years of age. Lack of prompt surgical correction by conventional valve replacement or interventional transcatheter aortic valve implantation (TAVI) increases the risk of morbidity and mortality, in the context of worsening clinical picture. Since the first interventional transcatheter valve implantation procedure in 2012 and to date, the evolution of technology and refinement of medical techniques has led to the refinement of the treatment method and thus to the improvement of the prognosis of patients with aortic stenosis undergoing TAVI after only one month.
Thromboprophylaxis in COVID-19

Published: January 2023

Abstract
The SARS-CoV-2 pandemic and its specific respiratory pathology has generated extensive research that has highlighted the specific nature of the disease (COVID-19). Thrombotic processes in the macrocirculation and microcirculation were among the first reported, accompanying respiratory (pulmonary) manifestations. Of the COVID-19 complications, thrombosis in the venous system (venous thrombosis and pulmonary embolism) and the atrial system (stroke) are the most numerous and severe in terms of evolution and prognosis. The prophylaxis of thrombotic processes in COVID-19, initially empirical, has gained a scientific basis based on research and experience of clinicians.
The current paper presents general data on macro- and microcirculatory thrombosis and the rationale for thromboprophylaxis. Thromboprophylaxis in non-hospitalized COVID-19 patients, “non-critical” and “critical” hospitalized patients and possible post-hospital thromboprophylaxis are presented.
Heparins (HGMM and HNF) are the most commonly indicated and used antithrombotic agents. Other antithrombotic agents - antiplatelets and direct anticoagulants (oral - DOAC) have a very limited and possibly negative role in thromboprophylaxis in COVID-19.
Cardiac Rehabilitation of Patients Following Myocardial Infarction

Published: January 2023

Abstract
Myocardial infarction (MI) - represents cardiomyocytes necrosis due to prolonged myocardial ischemia, occurring in the context of an imbalance between myocardial oxygen supply and consumption. According to the National Bureau of Statistics, in 2017, mortality from cardiovascular diseases made up 58.4% of all deaths, of which ischemic heart disease (IHD) constituted 52.5% and 8.5% were due to acute myocardial infarction.
Cardiovascular rehabilitation is used to optimize the physical, psychological and social functioning of the patient who suffered a myocardial infarction. The session includes 3 phases: the warm-up, the actual training and the recovery (relaxation) phase. The program is individualized, so it is necessary to correctly select the type, intensity, duration and frequency for maximum therapeutic effect.
Exercise-based medical rehabilitation is a supplement to drug therapy and post-infarction interventional surgery, as it improves cardiopulmonary function, optimizes drug therapy, decreases risk factors, increases exercise tolerance, improves mental status, reduces the risk of repeated heart attack and cardiac mortality. There are fewer complications due to bed rest and increased performance as a result of improved hemodynamic and metabolic function. As part of a cardiac rehabilitation program, physical activity helps with psychological adaptation and contributes to a successful return to work.
When policy clashes with practice: The case of teaching assistants in the Czech Republic

Published: January 2023

Abstract
Since the mid-2010s, Czech Republic has been implementing inclusive education measures on a wide scale. Five stages of supportive measures have been introduced, including the assignment of teaching assistants (TAs) for students with special educational needs. In the four years since the main reform, the assignment of TAs has become the most implemented supportive measure, even as their role in promoting inclusive education has been questioned in the scholarly literature. We base our findings on empirical research in primary schools and relevant policy documents. This paper focuses on the clashes between policy intentions and the practice of incorporating TAs into classrooms. We organise the findings into four categories of policy/practice conflicts: (1) ambiguous TA job descriptions; (2) insufficient TA qualifications; (3) combined TA contracts due to lack of funding; and (4) inconsistencies in TA appointments. Our findings suggest that, in practice, policy-regulated measures often do not correspond to the actual needs of schools.

Published: January 2023

Abstract
Czech parents place particular emphasis on ensuring the overall quality of life of their child when choosing a school. Our study shows how rural state schools understand this demand. A mixed approach was used in our research. In the first step, administrative data from all schools in municipalities with a population of up to 3,000 was used to shortlist 91 schools in demand by both catchment and non-catchment families. In the second step, socio-geographic data on type of municipality, online presentations, and other documents of the shortlisted schools were analysed. In the last step, case studies of 13 schools were prepared on the basis of parent surveys and interviews with stakeholders. We present case studies of three schools with different explicitly expressed approaches to satisfying parental preferences through a specific mix of care for well-being and valued characteristics of the rural environment. Our study adds to the existing literature on school choice and school leadership by describing specific developmental and/or marketing strategies of rural schools based on the real or perceived characteristics of the countryside.
Evaluation of Crushed Fine Materials
Authors: Gram Annika , Lagerblad Björn 
Published: January 2023

Abstract
As natural resources of sand and fine material used in the concrete industry are becoming more scarce, crushed materials are being used to a greater extent. Shape and texture of machine crushed materials differ from aggregates naturally ground, layered and sorted under the course of millions of years. It is assumed that crushed aggregates are more angular and of less smooth texture than natural aggregates, which will affect the flow behaviour of a suspension containing crushed material. In the mix design process of cementitous suspensions, an adequate rheology of the micro mortar (all constituents in the concrete being able to pass a 0.125 mm sieve, including the cement) is crucial. In this paper, the shape of fine particles is linked to the micro mortar plastic viscosity of the filler suspension including cement. The plastic viscosity here serves as an important quality assessment of the filler, since the micro mortar workability features are vital for the final mix design quality of the concrete workability.

Published: January 2023

Abstract

Introduction.
Due to the complexity of decathlon resulting from the number and diversity of the component events as well as difficult and time-consuming training required of athletes, high sports performance in this combined form of competition may depend on several factors.

Material and Methods.
The objective of the paper was to subject the careers of the world’s top decathletes competing between 1985 and 2018 to the principal component analysis (PCA) in order to explore and define interdependencies between the component events and the final result in decathlon at four stages of sports career development (from U20 – junior, through U23 and athletic excellence stage to decline in athletic performance).

Results.
The results made it possible to define the majority of the principal components determining high performance in decathlon.

Conclusions.
The analysis has shown that each sports ontogenesis stage has shared elements and a specific arrangement of events for every age category.
Crisis-Resistant Tourists – A Study of Hotel Online Reviews in the Times of Covid-19
Authors: Jezierski Adam , Wszendybył-Skulska Ewa , Kopera Sebastian 
Published: January 2023

Abstract

Introduction.
Tourists traveling in the times of crisis have a higher tolerance for risk and can be called ‘crisis-resistant’. The fact that they are ready to travel even if it is burdened with additional stress and obstacles makes them a valuable market segment for hoteliers, which is worth striving for particularly in the current pandemic situation. The research aims at better understanding of contemporary ‘crisis-resistant’ tourists through in-depth analysis of electronic Word of Mouth (eWOM).

Material and methods.
A web scrapping method was applied to acquire eWOM content posted by tourists traveling in the times of Covid-19. A total of 1239 reviews from 455 hotels were analyzed. Six hypotheses were tested with the use of T Test and Chi Square test.

Results.
The type of travel and the month of travel did not influence the frequency of coronavirus mentions. Similarly, reviews relating to COVID-19 did not vary in score nor in frequency of managerial replies. However, mention of coronavirus influenced the length of the review and its helpfulness.

Conclusions.
Crisis-resistant tourists treat issues related to the pandemic (including some in-hotel regulations and restrictions) as any other aspects of the hotel performance and accept them. Interestingly, those aspects do not negatively influence the total evaluation of the hotel, which may suggest that such tourists have already adapted to all the pandemic-induced burdens. At the same time, hotel managers fail to respond timely and adequately to negative comments, which seems to be of the key importance in such a situation.

Published: January 2023

Abstract
The objective of this study is to evaluate the effect of pozzolan on the durability of high-performance fiber concretes in two aggressive environments. For this, prismatic test pieces were made at (0%, 10%, 20%, and 40%) of pozzolan and immersed in two acids, hydrochloric and sulfuric. Then characterizations were carried out, such as the loss of mass, the depth of degradation and the mechanical resistance. The results obtained show that with the substitution rate of pozzolan, the loss of mass and the depth of degradation increase in the two acids, while the mechanical strength increases in hydrochloric acid and decreases in sulfuric acid.

Published: January 2023

Abstract
The aim of this research is to assess the mechanical performance of self-compacting concrete containing different percentages of fine aggregates, produced from the wastes generated by the cement plant industry and construction sites. Eight mixes, incorporating cement kiln dust (CKD) and hardened cement waste with partial fine aggregate replacement of 5%, 10%, 15%, and 20%, were produced and compared with a control mix made with 100% of crushed sand. The workability properties (e.g., flowability, passing ability, and resistance to segregation) and mechanical properties (e.g., compressive, flexural, and splitting tensile strengths) of all mixes were evaluated. The results showed that concretes containing recycled fine aggregates proved to have the best mechanical properties, compared to one made with crushed calcareous sand. However, self-compacting concrete with high mechanical strength could be produced with up to 15% wt. CKD replacement and with 10% wt. hardened cement waste replacement.

Authors: Franek Michal , Macák Marek , Hubová Oľga 
Published: January 2023

Abstract
The characteristics of aerodynamic forces acting on an elliptic cylinder with an aspect ratio of 0.5 with a wind attack angle from 0 to 90° and subjected to the boundary layer wind tunnel were investigated. The model was initially calibrated and compared with the existing work. The aspect ratio of the investigated model was 0.5, and the model was emerging in a turbulent flow. The mean and fluctuating drag and lift coefficients were investigated. The minimum drag coefficient occurred in the wind direction of 0° and the maximum at 90°. The lift coefficient was the largest in the 30° wind direction and the smallest at 0°. Fluctuating coefficients were similar profiles as the mean coefficients. Around the 30° wind direction, an inappropriate phenomenon occurred, caused by the generation of asymmetrical vortices structures and wake instabilities.
