Published: October 2021

Summary
Coronavirus (Covid-19), which began in China as of 2019 and spread to almost all over the world in a short time; has shown that we need to plan our life with new strategies as well as changing our current lifestyle today. While we must implement new ways to prevent against Covid-19 and maintaining our healthy lives, we must also design new strategies for returning to sports and physical activities. Therefore, the purpose of this study was to reveal the return strategies for professional and recreational athletes during the quarantine periods in light of evidences. In this regard, firstly we examined the existing literature regarding return strategies to sports. As a result, individual performance and personal hygiene conditions should be considered, and athletic performance should be preserved while keeping a physical distance from teammates and others. The use of masks in sports should be encouraged, but new techniques should be developed by investigating the effect on performance. Consequently, for healthy individuals, low to moderate intensity (not high-intensity) exercise may be beneficial and recommend. However, due to the risk of spreading (person-to-person or contaminated surfaces), exercise is recommended in special places with good ventilation and the use of personal types of equipment.

Summary
Since physical activities affect the quality of life and activate a complete locomotor system, sports and physical activities can be treated as a determinant for a harmonious development of all child’s characteristics and anthropological characteristics. Because, childhood and youth are the most important formative periods, and some segments of development, for example, specific motor skills can be developed only with means used in sports, this research was conducted to find out do the fitness program (aimed at improving strength) after eight weeks had a positive effect on body composition and mobility and stability of subjects. A control group consisted of 11 female subjects and experimental group were 11 female subjects aged 16 years. The effects of the program on the fitness condition of the subjects were determined by assessing the body composition parameters (data obtained using the Body composition analyser TANITA BC-418) - the total percentage of fat tissue (FAT), the percentage of fat tissue segmentally (percentage of fat tissue of the left leg (FATll), right leg (FATrl), left arm (FATla), right arm (FATra) and body (FATb)) and estimation of mobility and stability levels - based on the application of Functional movement screening (FMS) method (seven tests) before and after the program is implemented. The success of the implemented program was confirmed because the program showed a statistically significant difference between the mobility groups of the subjects in the experimental in relation to the control group (deep squat t=3,464 p=0,006, step over a hurdle t=2,390 p=0,038, active lift of a stretched leg t=2,887 p=0,016, rotatory body stability t=3,130 p=0,011 and FMS t=5,721 p=0,000), and a positive effect on the composition of the body in terms of reduction of the percentage of fatty body has been shown segmentally.

Summary
The main aim of the present study was to examine the cardiovascular response, time-motion characteristics, game performance and rated of perceived exertion (RPE) during small-sided games (SSGs) with different number of players. The research group consisted of elite youth male soccer players (n = 18) (aged 16.5 ±0.71 years, maximum heart rate (HRmax) 196.42 ±5.31 beats.min−1) from the FC DAC 1904 Dunajská Streda U17 soccer club. Cardiovascular response measurements included heart rate (HR) expressed in minimum, mean and maximum values and time spent in different intensity zones. Total distance covered, high intensity running and the number of accelerations and decelerations were captured by GPS. Individual game performance and the number of technical-tactical actions were recorded during every SSGs. After the game time we collected the ratings of perceived exertion scores from each player. Results showed that SSG with small number of players (3 vs. 3) triggered the highest HR response with mean value 168.00 ±8.48 beats.min−1, players spent the most time in maximal intensity zone 0:09:06 minutes, of SSG duration. This format of SSG was the mostintense for the players´ cardiovascular system, but we can’t find statistically significant differences between the HR values in SSGs. External load was the most demanding in SSG1 too, like in internal load. The highest scores in individual game performance were recorded in SSG2. In RPE scores SSG1 was the most difficult from the players point of view. In conclusion, the present research demonstrates the effectiveness of SSG1 in training sessions. Therefore, the coaching staff has the possibility to choose between SSGs during training sessions according to their physical, technical, tactical and psychological objectives.
12 Months of Balance Training Decreases Ankle-Joint Injury Frequency in Young Girl Basketball Players
Authors: Nováková T. , Tufano J. , Veseláková A. 
Published: October 2021

Summary

Aim: Balance training can help reduce the frequency of ankle joint injuries in adults, but data on young girls is relatively scant.

Methods: Out of 91 female basketball players (7-16 years), 40 players were assigned to an experimental balance training group, and 51 players were assigned to a control group. Both groups performed their typical basketball training but the experimental group performed additional balance-focused exercises during the warm-up of their basketball training sessions.

Results: A total of 47 girls (52 %) reported at least one ankle joint injury in their entire basketball history (52.5 % in the experimental, 50.9% in the control group). There was a positive correlation between the number of ankle joint injuries and age before the experiment (r = 0.34, p < 0.001). During the 12-month study period, girls who participated in balance training suffered significantly fewer ankle joint injuries than the control group (χ2 = 3.8423, df = 1, p-value < 0.05). Increased risk for ankle joint injury in the future was confirmed according to logistic regression for girls with previous ankle joint injury in history (4.33 times) and girls who did not participate in the balance training program (3.97 times).

Conclusions: A progressive, barefoot balance training program that is simple and short enough to be performed during normal warm-ups can reduce the likelihood of suffering an ankle joint injury in young girls basketball players, which may be useful for athletes in other sports as well.

Published: October 2021

Summary
The variables impacting the efficiency of the offensive phase of the game in ice hockey may be determining factor for both the training process and game strategies. The research aimed to acquire and expand the knowledge about selected goal-scoring characteristics in the National Hockey League. A total of 511 even-strength goals were recorded in 129 randomly selected games in a regular-season 2020/2021 by indirect observation. Goals were differentiated by selected variable dimensions: location of the offensive team’s puck possession gain before scoring a goal, game situation preceding a goal, and the number of passes of the offensive team preceding a goal. Data were analyzed by performing a one–way ANOVA. Post hoc multiple comparisons were performed using the Tukey HSD test. The significance level of p ≤ 0.05 was used. Significant differences were found within all variable dimensions (p= 0.00001). In terms of the puck possession gain location, zone 1 (along the boards in the offensive zone) was the zone with the significantly highest mean score (p= 0.00305). Offensive zone play was significantly the game situation preceding most of the goals (p= 0.00000). The interval of the passes that preceded most of the recorded goals was the interval of 1 – 2 passes (p= 0.00000). Acquired results point out the dominance of particular variables and may help coaches to determine the content of the training process and game strategies. Based on the assumption of the realization of similar research in different environments in terms of the quality and age category, if the analogy would be found between the results of the present study and the results of potential studies, we can state the trends applicable to youth training.

Published: October 2021

Abstract
The structural, electronic and optical properties of the of ScxGa1-xP alloys have been investigated by using the full-potential plane-wave FP-LAPW method as implemented in the Wien2k code. The exchange-correlation (XC) energy of electrons was treated using the Perdewe-Burke-Ernzerhof parametrization (PBEGGA), and the Tran-Blaha modified Beck-Johnson potential (TB–mBJ). The lattice constant and the bulk modulus have been calculated and analyzed where a deviation from Végard’s law is observed for both.
The calculation of the band structure of binary GaP shows that there is an indirect gap of 2.27 eV, while for the ScxGa1-xP compounds there are direct gaps with values of 1.91 eV, 1, 39 eV, 2.04 eV and 1.849 eV for x = 0.25, 0.5, 0, 75 and 1, respectively.
At ambient pressure, the refractive index and the dielectric constant are in good agreement with the experimental results. The extinction coefficient does not begin to increase until a threshold, which represents the optical gap. This threshold is equal to 1.224 eV and it starts to increase to reach a maximum at an energy of 3.551 eV.

Published: October 2021

Abstract
The industrial sector of the Polish economy plays an important role in ensuring the socio-economic development of the country. The Polish industry accounts for 24.1 % of the country’s employed population and 25.1 % of the GVA. The article aims to model the structural parameters of the Polish industrial sector according to the criterion of increasing product innovation level based on a comprehensive assessment of the Polish industry performance in the regional context. The offered method focuses on estimating the industrial sector at the macro and meso levels using a set of indicators for investment, innovation, labour activity, and profitability. Correlation-regression analysis methods were used to prove hypotheses about the impact of product innovation on employment and wages in the industry. To optimise the structure of the Polish industrial sector, an economic-mathematical model was developed, which was solved using the linear programming method. The target functionality of this model is the level of product innovation, at which the gross average monthly wage of Polish industry workers will double (to the EU average). The simulation results, which was based on data from the Central Statistical Office of Poland, provide an analytical basis for selecting industrial policy benchmarks for Poland.
Application of factor analysis in company management – selected examples related to competitiveness and market success
Authors: Jurczak Jolanta , Jurczak Grzegorz 
Published: October 2021

Abstract
Factor analysis is a standard statistical technique for reducing data dimensionality, which is widely used in sociology, psychology, and demography. Also, financial and insurance institutions commonly use such a technique for marketing research. In recent years, factor analysis has been used, at the beginning rather diffidently, to analyse selected problems of business management, e.g. to troubleshoot consumer and company communication. There are some literature reports about the successful use of factor analysis in managing a company area. Nevertheless, the literature seems to lack examples with successful use of the method with a clear explanation of its rather difficult application in the field of competitiveness or potential company boost. The modest popularity of such a powerful technique in this particular field seems to be attributed mainly to the complexity of the method and its requirements concerning the data quantity. Besides, the factor analysis technique has great potential and can be used as an efficient tool to reduce the complexity of observed phenomenon or verify the accuracy of theoretical models. Therefore, the purpose of this paper is to present a vast potential of factor analysis (both exploratory and confirmatory) applied to solve various problems in company management, especially related to competitiveness and market success. Two case studies covering the subject of business management are presented to illustrate the benefits of factor analysis application. The exploratory factor analysis is exemplified by the search of factors related to the commercial success of the company, while the confirmatory technique is illustrated by a case study of the intellectual capital of the company and its factors related to competitiveness. The paper also presents the essence of the factor analysis, types of analysis, subsequent procedures, purposes, and its specific features. Finally, the applicability of the factor analysis to solve management issues and possible gain in management are discussed.

Authors: Sujová Andrea , Simanová Lubica 
Published: October 2021

Abstract
The article aims to assess the improvement of the process capability by implementing the Six Sigma methodology in furniture enterprises with different levels of the quality management system (QMS) and ownership. The implementation of the Six Sigma methodology according to the DMAIC steps, also analysis, evaluation, and comparison of the implementation results were performed to improve the process performance. The implementation of the Six Sigma methodology was carried out in an international enterprise with foreign capital and a certified Quality Management System (QMS) and in a domestic enterprise with purely domestic capital without an established Quality Management System. The implementation results confirmed the positive development in the key indicators of critical processes, namely, in the reduction of DPMO, the increase of efficiency and the level of Sigma Process, and the values of process capability indices. The positive effects were more pronounced in the international enterprise compared to the domestic. The application of the Six Sigma methodology brings better results in manufacturing companies with international management skills and implemented certified QMS. These two aspects can be key success factors by managing and improving process capability. The practical contribution of the paper can be seen in the proposal of suitable methods and tools by implementing Six Sigma conception in furniture manufacturing regardless of the ownership or level of quality management systems.
Critical Evaluation into the practical utility of the Design of Experiments
Authors: Sharma Mithun , Sharma Shilpi 
Published: October 2021

Abstract
The research aims to emphasise the relevance of the Design of Experiments (DOE) technique as a reliable method for ensuring efficient use of statistical methods in routine industrial processes. A case study approach with a deductive strategy was used to assess the effectiveness of different DOE methods to achieve the desired objectives. Screening, mid-resolution and high-resolution DOE methods helped identify, characterise, and optimise an experimental variable against the desired output response. A general framework for effective DOE is provided as part of DOE planning, including defining DOE objectives, selection criteria, noise reduction, and application across industries. Overall, various DOE models proved successful in identifying a complicated relationship between experimental variables and output response. However, when ideal DOE models may not be feasible, reducing test run by choosing lower resolution DOE or fewer replicates can still provide important insights into the experimental variables’ impact on output responses.

Authors: Halicka Katarzyna , Surel Dariusz 
Published: October 2021

Abstract
The increasingly more visible trend of population ageing necessitates creating technologies supporting the functioning of older adults. Consequently, more gerontechnologies emerge designed to help the older adults in their daily functioning, from devices monitoring the health to special trolleys improving the mobility or Virtual Reality devices for active learning. This article aimed to determine the most desired group of gerontechnologies among current and future users. It focused on individual assessments of the most desirable group of gerontechnologies based on various criteria. The investigation aimed to find the criterion rated the highest in the selected group of gerontechnologies. The gerontechnology group was assessed against seven groups of criteria distinguished by the authors, i.e., Technology Innovation, Technology Demand, Social and Ethical Criteria, Technology Usability, Technology Functionality, Technology Ease of Use and Technology Use Risk. The survey was conducted in the form of a questionnaire, using CAWI (Computer-Assisted Web Interview) and CATI (Computer-Assisted Telephone Interview) methods, with the research sample comprised of 1 152 residents of Poland. Thus far, no studies have been conducted to evaluate this group of technologies based on the above-mentioned criteria.
Factors influencing the adoption of Building Information Modelling (BIM) in the South African Construction and Built Environment (CBE) from a quantity surveying perspective
Authors: Venter Berco , Ngobeni Sams Pfukani , du Plessis Hendri 
Published: October 2021

Abstract
The construction industry has often been described as stagnant and out-of-date due to the lack of innovation and innovative work methods to improve the industry (WEF, 2016; Ostravik, 2015). The adoption of Building Information Modelling (BIM) within the construction industry has been relatively slow (Cao et al., 2017), particularly in the South African Construction and Built Environment (CBE) (Allen, Smallwood & Emuze, 2012). The purpose of this study was to determine the critical factors influencing the adoption of BIM in the South African CBE, specifically from a quantity surveyor’s perspective, including the practical implications. The study used a qualitative research approach grounded in a theoretical framework. A survey questionnaire was applied to correlate the interpretation of the theory with the data collected (Naoum, 2007). The study was limited to professionals within the South African CBE. The study highlighted that the slow adoption of BIM within the South African CBE was mainly due to a lack of incentives and subsequent lack of investment towards the BIM adoption. The study concluded that the South African CBE operated mainly in silos without centralised coordination. The BIM adoption was only organic. Project teams were mostly project orientated, seeking immediate solutions, and adopted the most appropriate technologies for the team’s composition. The study implies that the South African CBE, particularly the Quantity Surveying profession, still depends heavily on other role-players in producing information-rich 3D models. Without a centralised effort, the South African Quantity Surveying professionals will continue to adopt BIM technology linearly to the demand-risk ratio as BIM maturity is realised in the South African CBE.

Published: October 2021

Abstract
The subject of this study is a preliminary risk analysis during travel by the low pressure railway Hyperloop. The main objective was to formulate recommendations related to the development of the project of the new transport mode. The main analysis was preceded by the identification of Man – Machine - Environment system. Undesirable events were identified for each of the specified steps of a ride. For each event, a risk assessment was performed using Risk Score based method. The causes, effects and preventive actions were also listed. Events with the highest risk score were indicated. The need to develop procedures for safety checks and emergency situations was pointed out. It was shown that the safety analysis of the transport system should be extended after a final project development of the railway system and the necessary infrastructure.
Analysis of the possibility of using a geogrid to improve load bearing capacity of natural airfield pavements
Authors: Kowalewska Agata , Włodarski Piotr , Pietruszewski Paweł 
Published: October 2021

AbstractThe article presents an innovative method that was verified in the field. It is aimed to improve the load bearing capacity of airfield pavements, which are one of the elements of the flight safety system. Airfield pavements protect the runway in case when the aircraft is taxiing beyond the runway. Moreover, they are also used to perform starting and landing operations of military aircraft. Due to this, they need to have an adequate load bearing capacity that ensures the safety of performing aircraft flights. Airports cannot afford to be shut down for a long time; thus, it is essential to look for efficient and fast solutions that could improve the load bearing capacity of airfield pavements. The authors suggested to apply geogrid immersed in natural airfield pavement.
