Talent Selection and Management in View of Relative Age: the Case of Swimming
Authors: Nagy Nikoletta , Földesi Gyöngyi , Sós Csaba , Ökrös Csaba 
Published: February 2019

Abstract
Based on our empirical research, through the analysis of the birthdates of young competitive swimmers, the present paper aims to examine the system of talent selection and management in Hungarian competitive swimming complemented with a new element. The research population consisted of the registered junior competitive swimmers participating in the new talent management program of the Hungarian Swimming Association (N=235; average age: 11.44) due to the decision of the Coaches’ Committee. Our research was based on the analysis of documents and databases. Besides the descriptive statistics, Chi-square tests and the Kruskal-Wallis test were applied. The results show that swimmers born in the first three months of the year are still more likely to be recruited in the program than their relatively younger counterparts. Furthermore, as a potential effect of the new program, the dominance of the first quarter of the year is also characteristic among those eligible for the next level of talent management. The new selection system of Hungarian swimmers is still highly sensitive to the relative age. Thus, it is recommended to further investigate the functioning of the new talent management program in terms of selection and success.
The Chain Reaction Between the Media and Sport. The Impact of Rule Changes in Handball
Authors: Marczinka Zoltan , Gál Andrea 
Published: February 2019

Abstract
A long, historical cooperation exists between sport and the media. The media can lift up the profile of a sport, and sport provides a marketable topic/product to talk about. Rules have been changed and playing conditions adapted to add to the glamor and spectacle of sport, thus making sport more marketable, enhancing media coverage and making it more appealing for the viewer. In the history of handball, rule changes have been introduced for the same purpose. However, changing the rules has a great effect on the team’s performance, and thus on the coaches’ work as well. There is no doubt that among the rule modifications introduced by the International Handball Federation (IHF) in 2016, substituting the goalkeeper for another court player during an attack without wearing a special shirt has had the greatest impact on the game in recent times. The main aim of the study was to carry out empirical research in order to analyze the recent rule modifications by the IHF, particularly when substituting the goalkeeper for an extra court player during an attack. The 2017 World Championship in France provided an ideal opportunity to collate data in order to explore how often and effectively teams used this rule change at the latest world event. In addition, we have also sought out the opinions of elite coaches concerning the state of current rules in handball and what they would change in order to make this sport discipline more marketable for the media and for spectators. The results show that teams substituted their goalkeeper for an extra court player when in numerical inferiority on average twice as much as when in numerical superiority and on average twice as often when losing as when winning. Surprisingly, the teams’ average scoring effectiveness was a little bit higher than when they played in numerical superiority or with an evenly reduced number of players. In addition, the outcome of focus group interviews shows that most coaches think that measuring the attacking time, introducing the third referee into the game, and having better judgment concerning the fast start-off is necessary for the betterment of the game.
Hero and Antihero: An Ethic and Aesthetic Reflection of the Sports
Authors: Perez Carlos Rey 
Published: February 2019

Abstract
In Ancient Greece, the figure of the hero was identified as a demigod, possessed of altruistic and virtuous deeds. When Pierre de Coubertin reinstated the Olympic Games, the athlete was personified as a modern hero. Its antithesis, the anti-hero, has more virtue that defects, no evil but he does not care on the means to achieve his goals. In the eyes of everyone involved in sports competition, these characters captivate and at the same time, create conflicts of ethics and aesthetics. The purpose of this paper is to perform an ethical reflection linked to principles that contribute for the human growth and accomplishment, as well as the aesthetic on the perception of the sensitive, reverberated by sensations and feelings emerging from athletes. Connecting the ethic with the aesthetic spheres, we could have in the sports a phenomenon walking toward a common point between moral and aesthetic, between the good and the beauty.
The Business of Sport, Sledging and the Corruption of Play – an Interpretation through a Huizingian-Bourdieu Lens
Authors: Duncan Samuel Keith 
Published: February 2019

Abstract
Using a combined Huizingian-Bourdieu framework, this paper analyses the significance of sport’s transformation into a business and how the prevailing business structure that defines professional sport has influenced the ‘lived experience’ of those playing at sport’s elite level. Furthermore, this paper highlights how the actions of players, coaches and other participants serve to reinforce, legitimise and normalise the business characteristics of sport’s dominant business structure.
Importantly, this paper illuminates how the professionalization of sport corrupts the act of playing and indeed gives rise to play tactics, such as ‘sledging’, which both reflects the increased seriousness of sport and, in its very execution, further reinforces the dominant business structures of professional sport, all the while corrupting the essence of sport – play.
In doing so we are challenged to consider how society’s fields could be different in structure, and in the ‘lived experience’ within the field.
Discussing the Scientific Evidence Generation and Psychological Research Methods in Postmodern Societies
Authors: Sesé Albert 
Published: February 2019

Abstract
Evidence generation by current Social and Health Sciences is coping with some important barriers that difficult credibility of scientific products. Information and communication technologies have a strong impact over social relationships in our postmodern societies. The incidence of post-truth in our context is generating a pernicious relativism, far from contrasting the information veracity. The aim of this paper is to analyze and discuss the challenges of research methods and statistical models, more specifically for Psychological research, taking into account the impact of novel techniques as big data and virtual reality. Special attention is also devoted to the discussion about statistical shortcomings of psychological research and to the reproducibility problem. Finally, some potential solutions are proposed to be applied in order to improve the quality of scientific evidence.
The People Demand Social Justice: The Social Protest in Israel as an Agoral Gathering
Authors: Zysberg Leehu 
Published: February 2019

Abstract
The summer of 2011 has seen the first mass-scale social protest in Israel in its 70 years of existence. This social wave that shook the country, showed unique characteristics a-typical of most social and political uprisings, that go largely unexplained by social theories of social change and crowd psychology. In this article I am analyzing published reports of the social protest of 2011, and draw the analogy with the concept of ‘Agoral Gathering’ that may account for these events and support discussion of their aftermath.

Published: February 2019

Abstract
The new Ion Beam Centre (IBC) equipped with 6 MV tandem ion accelerator and 500 kV ion implanter systems was built at the Slovak University of Technology, Faculty of Materials Science and Technology (STU MTF). The facility provides Ion Beam Modification of Materials (IBMM) and Ion Beam Analysis (IBA), which includes Rutherford Backscattering Spectrometry (RBS), Particle Induced X-ray Analysis (PIXE), Elastic Recoil Spectrometry (ERDA) and Nuclear Reaction Analysis (NRA). Presented are selected experimental procedures carried out in the IBC during the first year of operation. They present examples of a typical IBA performed, such as thin film characterisation in nm to tens of µm range, elemental depth profiles and sensitivity to the light elements enhancement by non-Rutherford cross-section regime application along with the crystalline sample channelling spectra and boron content measurement.
On the Problem of the Ion Energy Loss in Thin Absorbers
Authors: Minárik Stanislav , Riedlmajer Róbert 
Published: February 2019

Abstract
Exact determination of energy loss of ion in materials is still a non-trivial task because of relatively complicated changes of the ion`s stopping power S(E) during transport of the probing ion inside the material structure. Energy loss of ion in the material structure always depends on the current value of continually decreasing energy of the ion, indeed. A purely theoretical approach can be applied to the energy loss calculation in some typical cases. Average energy loss of ion can be determined by means of the Bethe-Bloch analytical theory (1-6) (in high velocity region) and the Lindhard-Scharff-Schiøtt (LSS) theory (7-10) (in low velocity region). Currently, there is no acceptable exact theory to determine the energy loss of ion in intermediate-velocity region (11) and experimental data must be used in that case. Basically, only a finite number of discrete experimental data is always available. Therefore, if the problem how much energy the projectile ion loses in a certain distance travelled is solved, the modelling of function S(E) based on some acceptable assumptions must be applied.
In this contribution, we present the energy loss calculations in intermediate-velocity region of ion based on linear interpolation of experimental data. Calculation was carried out for a kapton foil using the data taken from Ziegler, Biersack (12). Energy values of an ion along its trajectory inside the foil were found, and the mean projected range of ion penetrating into the foil was calculated. Finally, the energy resolution was evaluated taking into account straggling provided that the foil is used as an absorber in the ERDA experiment.

Published: February 2019

Abstract
The trace element analysis system is presented using Proton Induced X-ray Emission (PIXE) analysis at a new Ion Beam Centre in Trnava. Standard PIXE system dedicated to the measurement of thick solid samples was extended by a new application for trace element analysis in aerosol samples. The sample holder was modified with respect to the dimensions of the aerosol filters, and a new sample holder and a Faraday cup (FC) were made. The first results of the PIXE aerosol analysis are presented in this paper. Furthermore, the geometric efficiency of the detection system was verified using 55Fe radioactive source emitting monoenergetic Mn X-ray lines. The measured data were compared with the Monte Carlo simulations regarding/disregarding the X-ray attenuation.

Authors: Drienovský Marián , Trnková Lýdia Rízeková , Čička Roman , Priputen Pavol , Pekarčíková Marcela , Janovec Jozef 
Published: February 2019

Abstract
The influence of increased Cu and Ag contents on the microstructure evolution in the utilized Sn-0.3Ag-0.7Cu (wt. %) solder was studied. The utilized solder was exploited in the wave soldering process at the temperatures of about 260 °C for several days. The samples investigation involved the differential scanning calorimetry, the scanning electron microscopy including the energy dispersive X-ray spectroscopy, and the X-ray diffraction techniques. To predict phase equilibria at various temperatures and temperature dependences of heat capacity, the Thermo-Calc software and the COST531 lead-free solder database were used. The original and the utilized solders were found to be very similar regarding the phase occurrence, but slightly differ from one another in microstructure evolution due to higher bulk contents of Cu in the latter solder. The obtained results contribute to both the better understanding of the microstructure evolution in low-silver Sn-Ag-Cu solders and the determination of compositional limits for those solders used in the wave soldering process.

Published: February 2019

Abstract
Borated austenitic stainless steel is used in nuclear industry due to the high neutron absorption efficiency. The plasma, laser and electron beam welding experiments were used for the study of the weld joints microstructure. The microstructure changes caused by welding process were observed by light optical microscopy and transmission electron microscopy. The microstructural characterization and microchemical analysis showed significant changes of the phase composition in the weld metal mainly. The austenitic dendrites were surrounded by eutectics, which were the mixture of the M2(C,B) and M23(C,B) borocarbides, δ-ferrite and austenite.

Conveyance of the Dramatic Work El Gran Galeoto by José Echegaray to the European Scene and His Reception in Bratislava at the End of the 19th Century
Authors: Laslavíková Jana , Calvo Beatriz Gómez-Pablos 
Published: February 2019

Abstract
This study looks at the work of Spanish playwright José Echegaray and the circumstances of his domestication on the European theatre stages at the turn of the 20th century. One of his most important works, El gran Galeoto55, arrived in Bratislava in 1889, only one year after its premiere in Vienna and three years after the opening of the new building of the Bratislava City Theatre. The premiere of the work, translated into German and in a theatrical adaptation from Paul Lindau’s pen named Galeotto took place around the same time as the premiere of the work Ralph William from the domestic author Josef Julian, which thanks to a similar theme was perceived as «Bratislava’s Galeotto».

Contribution of Slovak Directors to the Profile of the Czech Opera Theatre After 1993
Authors: Mojžišová Michaela 
Published: February 2019

Abstract
The ambition of the survey study, which maps the work of Slovak directors in Czech opera theatres after 1993, is to identify the number of Slovak creators in the opera-theatre discourse of the very closely connected countries in terms of culture and history while at the same time adding the professional biographies of Slovak artists – who are little known and reflected upon in their homeland – and parts of their works. The author concludes that the split of the Czechoslovak Republic and the subsequent creation of separate Czech and Slovak Republics did not have an adverse effect on the mutual contacts of our opera cultures. At present, we even enjoy intensified co-operation in both directions. The nonjudgmental attitude of Czech theatres towards the influence of Slovak film directors in the Czech Republic is clear: not only credible creators (Marián Chudovský), but also representatives of the younger generation of opera directors (Andrea Hlinková) and renowned drama directors with previous opera experience (Martin Huba, Roman Polák), as well as creators who had not yet worked on the opera scene at home (Martin Čičvák, Sláva Daubnerová) were presented with an opportunity to contribute. Despite the fact that their works represented the enrichment of the Czech opera-theatre, the Slovak director with the most significant contribution to the Czech opera theatre remains Jozef Bednárik, even two decades later.
Possiblities and Limitations of Translation of Slovak Drama Into Polish Culture
Authors: Spyrka Lucyna 
Published: February 2019

Abstract
The Polish and Slovak languages, as well as Polish and Slovak cultures, are considered very similar, so it would initially appear that there would be no obstacles limiting the possibilities of translating Slovak drama into Polish. It turns out however, that Slovak drama is not often translated into Polish. Older translations that were presented in Polish theatres were rarely followed in the press, and today they have been forgotten. On the contrary, current translations are published far more often than staged. The presented study evaluates this situation as a result of several limiting factors. In addition to the political conditions of cultural exchange and the manner in which publishers and theatres operate in Poland, there is also a linguistic closeness that negatively impacts on the quality of translations, as well as the stereotype of Polish and Slovak cultural proximity, which limits the interest of Polish audiences in Slovak drama.

Authors: Živković Slavoljub , Nešković Jelena , Medojević Milica Jovanović , Bajić Marijana Popović , Ostojić Dejan 
Published: February 2019

Summary
Introduction Efficient cleaning and canal design present a basic precondition for successful endodontic treatment. The aim of this study was to evaluate, using SEM analysis, the efficacy of cleaning the apical third of the canal with one instrument in both reciprocating motion and full rotation systems.
Materials and methods Thirty (30) single-rooted teeth (upper incisors), extracted due to periodontal reasons, were used and selected in 2 groups. In the group 1, instrumentation was done with a single instrument UNICONE with reciprocal movements (MEDIN, Czech Republic), while in the group 2, a single instrument XPS endo SHAPER (XPS) (FKG, Dentaire, Swiss) with full rotation was used. 2% solution of NaOCl and 17% EDTA solution were used as irrigation agents in both groups. SEM analysis of smear layer in the apical third was done at standard magnification of 1000x and presented on a scale of 1-5.
Results showed mostly clean canal walls and no smear layer in the apical region in both tested groups. Canal walls were somewhat cleaner after using UNICONE with reciprocal movements (80%) compared to the canals instrumented with XPS ENDO SHAPER (76%), but this difference was not statistically significant.
Conclusion Single-file NiTi systems did not remove smear layer completely, but provided efficient cleaning in the apical part of the canal. UNICONE file with reciprocal movements was somewhat more efficient in removing smear layer compared to the full rotation XPS ENDO SHAPER file.

Published: February 2019

Summary
Introduction In everyday clinical practice, we often encounter a lack of space for placing all the teeth present into dental arch; therefore it is often recommended to extract teeth within orthodontic treatment. In clinical practice, the most commonly used methods of closing space after are elastic chains and NiTi closed spiral springs. The aim of this paper was to compare postextraction space closure speed using two different sliding mechanisms, NiTi closed coil springs and elastic chains within treatment with fixed orthodontic appliances.
Material and Method The total sample in this study consisted of 46 postexstraction spaces in 23 patients indicated for the extraction of first premolars using treatment with fixed orthodontic appliances. Two sliding mechanisms, NiTi closed coil spring and elastic chains were applied to postextraction space closure. Postextraction spaces were monitored for 4 months with appointments every 4 weeks. During appointments mechanisms were activated and digital caliper was used to measure the width of the postextraction space.
Results The results showed that NiTi closed coil springs method achieved greater reduction in postexstraction space (3.94 mm) while with elastic chain method the closure of 3.10 mm was achieved. The total difference between these two methods in the observed period was 0.84mm and no statistically significant difference was found (p> 0.05). The lowest value for NiTi closed springs was 2.19 mm, while for the elastic chain it was 1.29 mm. The best postextraction space closure was 5.70 mm and it was completed using NiTi closed springs while for elastic chain the best value was 4.80 mm.
Conclusion: NiTi closed coil springs lead to faster closure of postextraction spaces in relation to elastic chain. Since this difference is minimal, in practice, both methods can be used equally.
