Rescue of persons in traffic accidents on roads
Get PDFThe article deals with traffic accident rates in the Czech Republic and activities of the basic component parts of the integrated rescue system in relation to traffic accident addressing. On the basis of statistical data from the period 2011 to 2018, the purpose of the main component parts of the integrated rescue system in providing aid to victims of traffic accidents is emphasized. A real traffic accident is used to describe the intervention procedure with an emphasis on disentangling individuals from wrecked motor vehicles and provision of pre-hospital emergency care. Assessment of traffic accidents and the methods of their addressing are summed up in proposals for the safe rescue of victims, provision of (first) aid, and elimination of intervention-related complications.Slovenská Akadémia Vied, SAV: VEGA 1/0638/19; Ministerstvo školstva, vedy, výskumu a športu Slovenskej republiky; Kultúrna a Edukacná Grantová Agentúra MŠVVaŠ SR, KEGA: 049TUKE-4/2020Scientific Grant Agency of the Ministry of Education, Science, Research and Sport of the Slovak Republic; Slovak Academy of SciencesSlovak Academy of Sciences [VEGA 1/0638/19, KEGA 049TUKE-4/2020]; Cultural and Educational Grant Agency of the Ministry of Education, Science, Research and Sport of the Slovak Republic; [VI04000080]; [RVO/FLKR/2020/03
Analiza materiału konstrukcji obiektu z brązu w modelach 3D chmury punktów
No full textThe study deals with experimental research of the material of a bronze work of art. It characterizes the visual properties of the metallic material for perception by the human eye and lists the expected undesirable properties that may affect the quality of reproduction of the work in a 3D model of point clouds. The text also presents image capture for the use of the photogrammetry method. This method was used for 3D modelling of a real object in the exterior. The human eye is a significant environment of the perception of the object and the 3D modelling process. Lighting conditions also significantly affect the quality of the captured image and its processing into a point cloud. The results of the image quality of the original art transferred to the 3D environment reveal the essential attributes of the work when capturing the image. The experiment aims to determine the fundamental aspects influencing the image work with metallic objects and its conversion in the form of point clouds into 3D models for use in virtual reality. Attention is paid to the quality and complexity of processing the reproduction of the object into a point 3D model. And the influence of the properties of the metallic material and the surrounding exterior environment on 3D modelling by photogrammetry.IGA/CebiaTech/2021/00
Owners vs. managers. Disparities of attitudes on the business risk in SME segment
Get PDFThe article aims to identify disparities in the perception of business risks between the owners and managers of small and medium-sized enterprises (SMEs) in the V4 countries. The statements of strategic, market, personnel, legal and operational risks are the research's subject. Disparities of attitudes on the business risks were verified on the sample of 1585 SMEs by the mathematic method with the non-parametric approach – the Kruskal-Wallis test. The most significant disparities are in the perception of the adequacy of the market risk’s level in the case of SMEs. The owners are significantly more optimistic in their market risk assessment than the managers of SMEs. On the other hand, the managers compared to the owners present a more pessimistic assessment concerning the statement that the business environment in their field of doing business is over-regulated. The respondents presented the same attitudes in the cases of the operational and personnel risk statements. Continuity of views and the perception of the business risks are critical factors for the growth of SMEs’ business performance. Implications and consequences are generally valid for all SMEs, not only the ones from the V4 countries. © 2022, Amfiteatru Economic. All rights reserved
The influence of the Generation Z's perception and psychological ownership on repurchase intention of e-shopping: Evidence from Vietnam
Get PDFOne of the most significant achievements of Information Communication Technology (ICT) in commerce is e-shopping, which changes shopping behavior in the retail sector. This research examines how Generation Z's perceptions of e-shopping benefits and drawbacks and A qualitative method through in-depth interviews and a quantitative method via a questionnaire survey is employed to assess the Generation Z-ers' attitudes, perceptions, and psychology toward the benefits and drawbacks of e-shopping and their intention of choosing this channel for repurchasing. PLS-SEM will be associated to discover the relationships between Generation Z-ers' psychological ownership, perceptions of e-shopping benefits and drawbacks, and their online repurchase intention. Findings suggest that Generation Z-ers' online repurchase intention is due to perceived benefits, psychological ownership, and is regardless of perceived drawbacks. Furthermore, as a moderator of the effect of perceived drawbacks on repurchase intention, psychological ownership may lessen the Generation Z-ers' concerns of e-shopping drawbacks and enhance their online repurchase intention.Internal Grant Agency of FaME TBU in Zlin [IGA/FaME/2020/011
Antimicrobial properties of polymeric nanofibrous membranes containing ferrous sulphate
Get PDFThis paper reposts on nanofibers of polymers doped with ferrous sulphate (FeSO4) possibly in combination with quaternary ammonium salt (QAS) prepared by electrospinning. Three types of polymers (polyvinylidene fluoride/PVDF, polylactic acid/PLA and polyurethane/PU) with good electrospinning processability and good mechanical properties of nanofibers were chosen. The prepared nanofibrous membranes were characterised in terms of morphology of the fibres assessed by SEM, and the pore sizes were determined by porometry. The leaching test showed a firm anchoring of the additive in the nanofiber structure. Antimicrobial activity was monitored after 0 h, 4 h and 24 h using Staphylococcus aureus (CCM 4516) and Klebsiella pneumoniae (CCM 4415) strains. Furthermore, aerosol filtration efficycy was dermined and also quality factor of filtration. The membrane prepared from PU doped with FeSO4 showed the best antibacterial efficiency. The porosity and morphology of the nanofibrous membrane effectively contributed to the trapping of microorganisms. This system was also evaluated as the most suitable for the electrospinning process from the effectivity point of view. Spinning ang dopping process of preparation is easily applicatbole to the the industrial conditions of production which is very importatnt aspect of this submitted scientifique work. © 2021 NANOCON Conference Proceedings - International Conference on Nanomaterials.

On a generalized form of multiset finite automata with suppressed nonfinal states
No full textThe paper presents a generalized form of multiset finite automata. An important feature of the form is that all or almost all of its states are final. This leads to a new description of semilinear languages (which correspond to languages accepted by multiset finite automata) and can be used as a suitable tool for solving various problems from formal multiset languages theory. © 2022 American Institute of Physics Inc..

Fever status detection using artificial neuron network
Get PDFThis research paper proposes a monitoring system and a prototype that has been developed for detecting if a when fever is present in senior citizens or any other specific groups of people requiring continuous care. With various issues affecting the health of senior citizens, it is imperative to continuously monitor their health status. The monitoring system is beneficial as it will make it feasible to enable the real time detection of fever and thus allowing for the early treatment. Delaying treatment can lead to the underlining health issue going beyond the remediable condition. Thus, quick detection is vital. There are various issues that might causes illness in people. Some of the issues include virus outbreak, seasonal infections, disease, and old age. In this paper our focus is mainly on old age. This group of people is much more at risk of getting ill or frequently need more attention. In this project, the presence of fever or illness has been detected by using artificial intelligence (AI). The AI technique that is utilized in this project is artificial neural networks. The computation is done by first training the system and then secondly validating the trained system. After the training, the system is supplied with a new set of data, with a known state, to validate that the training was successful. To validate the system, it is provided with sample data to test its efficiency. If the system is well trained the validation data would label that data correctly. That label is known before the validation test, as the sample data had known labels. These known labels were not given to training but not validation system. The system is function properly if its label matched the sample data label. The conducted experiment demonstrated a successful detection with an efficiency rate of 82 percent.Faculty of Applied Informatics, Tomas Bata University in Zlin [IGA/CebiaTech/2021/001
Solow model with technological progress: An empirical study of economic growth in Vietnam through ARDL approach
Get PDFThis study aims to clarify the relationship between technological progress and economic growth in Vietnam. This investigation used annual data from the World Bank related to Vietnam from 1985 to 2019 and applied the approach of autoregressive distributed lag to evaluate the impact of technological progress on economic growth in Vietnam in the short and long term. The regression equation constructed in this investigation came from the analysis of the Cobb-Doulag equation and the Solow model. The results of the study showed that GDP per capita is affected by the variables of technological progress in the short and long term, which means that technological progress affects economic growth in Vietnam. This study also contributes to the area of economic growth research in Vietnam with important evidence-based results on the impact of technological progress on GDP per capita, and the findings of this study have several implications for the understanding of the role of technological progress in economic development. The current study is still limited to small sample sizes and does not cover all indicators for analysis; however, it provides the foundation for future investigations with larger sample sizes, and other elements of technological progress are modified and applied in specific fields.Internal Grant Agency of FaME TBU in Zlin [IGA/FaME/2020/011-Investigation]; Southeast Asia regionIGA/FaME/2020/01
The impact of gender-role-orientations on subjective career success: A multilevel study of 36 societies
Get PDFWe investigate the relationships between gender-role-orientation (i.e., androgynous, masculine, feminine and undifferentiated) and subjective career success among business professionals from 36 societies. Drawing on the resource management perspective, we predict that androgynous individuals will report the highest subjective career success, followed by masculine, feminine, and undifferentiated individuals. We also postulate that meso-organizational culture and macro-societal values will have moderating effects on gender role's impact on subjective career success. The results of our hierarchical linear models support the hypothesized hierarchy of the relationships between gender-role-orientations and subjective career success. However, we found that ethical achievement values at the societal culture level was the only variable that had a positive moderating impact on the relationship between feminine orientation and subjective career success. Thus, our findings of minimal moderation effect suggest that meso- and macro-level environments may not play a significant role in determining an individual's perception of career success
Empirical identification of the chief digital officer role: A latent Dirichlet allocation approach
Get PDFThis study examines the global demand for Chief Digital Officers (CDOs) to determine a universal CDO archetype in terms of competencies and tasks. It uses Bayesian statistics and Latent Dirichlet Allocation (LDA) topic modeling to measure multiple dimensions in a sample of 518 job postings for CDO positions. Findings show the hybrid nature of newly appointed CDOs, who feature a mixture of both business administration and technological skills. Further, the study highlights the pivotal role of CDOs in terms of strategic change in companies. The study has three major contributions. First, it showcases the value of LDA in job profiling research. Second, it bridges the existing knowledge gaps in CDO literature with empirical evidence from a global dataset and identifies a core CDO profile based on data extracted through LDA. Third, it illustrates the current market requirements for CDO positions, which is useful to both companies and candidates. © 2022 Elsevier Inc
