Purpose: The aim of the article was to analyse the qualitative approach to product improvement by Small and Medium Enterprises (SMEs) from the Visegrad Group (V4) countries (Poland, Slovakia, Czech Republic, and Hungary). Design/methodology/approach: The analysed results included a research sample of 379 companies in the electromechanical industry (machinery processing industry). The sample was obtained between March and September 2023 by means of a guided survey. Analyses of the results of quantitative research were carried out to verify the approaches of SMEs from V4 countries to pro-quality product, including comparative analyzes of the results obtained. Analyses were performed using the ANOVA test (repeated measure designs). The Mann Whitney U test was used to identify statistically significant differences in entrepreneurs' responses. The significance level adopted was a = 0.05. Findings: It has been shown that SMEs from V4 countries have different approaches to improving product quality. Additionally, it was shown that both in the case of pro-quality activities of SMEs from the V4 countries, the lowest consistency of assessments occurs in the following countries: Poland and Slovakia, Poland and Hungary, Slovakia and Hungary. Practical implications: Research results may contribute to more effective and coherent development activities of SMEs in the V4 countries as part of their sustainable development. Social implications: Based on the research conducted, it is possible to provide SMEs in V4 countries with a more adequate approach to undertake consistent and effective quality activities as part of the improvement of the product. Originality/value: Determining the current pro-quality approach to product improvement in SMEs in the V4 countries. The novelty is also the identification of the importance (level of importance) of these approaches in each V4 country, as well as the determination of the similarities and differences between these approaches in SMEs from countries in the Visegrad Group.

Purpose: The aim of the article was to analyse the pro-environmental approach to products improvement by SMEs from the Visegrad Group (V4) countries. Design/methodology/approach: The research was survey. The survey research was carried out in traditional (paper) and electronic form (MS FORMS). The survey was directed at electronic industries (machinery processing) belonging to small and medium enterprises (SMEs) from V4 countries. The results presented in the article refer to sample size of 379 SMEs, obtained between March and September 2023. Results were analysed in statistical way, i.e.: ANOVA test and Mann Whitney U test by significance level equal to a = 0.05. Findings: SMEs in V4 countries have a similar approach to pro-environmental improving of products. It was shown that pro-environmental activities of SMEs from the V4 countries, the lowest consistency of assessments occurs in the following countries: Poland and Slovakia, Poland and Hungary, Slovakia and Hungary. Practical implications: The research results may contribute to more effective and coherent development activities of SMEs in the V4 countries as part of their sustainable development, and also to take appropriate actions that will be supporting qualitative and environmental products. Social implications: The results can help SME entrepreneurs improve their products to protect the natural environment. In addition, they can be the basis for the development of SMEs from the V4 countries and their unidirectional development, which includes not only improving the quality of products, but also caring for the environment. Originality/value: The originality of the research is the determination of the current pro-environmental approach to product improvement in SMEs in the V4 countries. The novelty is the provision of current data on the importance of improving pro-environmental products in SMEs from the V4 countries and their comparison between companies in the electrical machinery industry.

Purpose: The purpose of the research was to perform an in-depth comparative analysis of proquality and pro-environmental approaches to the products improvement in SMEs (belonging to the electrical machinery industry industry) from V4 countries. Design/methodology/approach: An in-depth comparative analysis of pro-quality and proenvironmental approaches to product improvement was carried out in SMEs from V4 countries. Based on previous research (survey research conducted from March to September 2023 including 379 SMEs from V4 countries), two benchmarks for these approaches were developed and further analysed. Statistical analyses were used, i.e. Box-and-whisker chart and Wilcoxon paired test in STATISTICA 13.3. on the level of significance p<0.05. Findings: It was shown that SME entrepreneurs from V4 countries have a relatively similar approach to the improvement of pro-quality and pro-environmental products. The pro-quality approach is more important than pro-environmental in case of product improvement. Practical implications: Research results can be the basis for defining more precise directions for the development of SMEs in V4 countries and increasing cooperation between consortium regions in the development of product production in line with the idea of sustainable development and current customer expectations. Social implications: The results can have a positive impact on public attitudes, mainly entrepreneurs from SMEs, but not only in making further efforts to improve the quality of products while reducing the negative impact on the environment. This behavior may contribute to increased customer satisfaction with purchased products, but also to the development of the economies of the V4 countries and to meeting the requirements of sustainable development. Originality/value: Originality of the research includes determining the current approach of SMEs in the electrical machinery industry in V4 countries to meeting customer expectations regarding product quality, while striving to achieve environmentally friendly products.

Purpose: The purpose of this paper is to investigate whether the capital structure of stock exchange listed companies in individual countries of the Visegrad Group differs significantly, and whether these entities can be considered to be organizations implementing the principles of the golden and silver rules of accounting. Design/methodology/approach: The research hypotheses assumed were verified using appropriate statistical tools. Calculations were per-formed using the Gretl software and MS Excel. Findings: The basis for operating activity financing in the companies under examination mainly entailed equity. In practice, this means that most of the entities surveyed follow the silver, less frequently the golden (the more restrictive), rule of accounting. The results obtained for each country of the Visegrad Four differed significantly. The research conducted provides a basis for determining whether the golden and silver rules of accounting constitute factors affecting the decision-making regarding capital structure formation in companies listed in the Visegrad Group countries. The study covers companies listed in the four countries and provides a basis for further research in this area, with respect to both the sample size and the time series length. Research limitations/implications: The paper takes into account only listed companies, so its results do not explain capital structure behavior of other companies. The research is a contribution to further analyses of the capital structure, which covers all types of enterprises. Practical implications: The research conducted provides a basis for determining whether the golden and silver rules of accounting constitute factors affecting the decision-making regarding capital structure formation in companies listed in the Visegrad Group countries. The study covers companies listed in the four countries and provides a basis for further research in this area, with respect to both the sample size and the time series length. Originality/value: The most important principle of financing is that firms should try to match the characteristics of the financing as closely as possible to the characteristics of the assets being financed. Unfortunately, only a few studies on this subject can be found, especially internationally. Our research aims to fill a gap in the literature on the subject. It made possible to identify financing rules characterizing capital structure of the companies operating in different economic conditions. The study may be addressed to analysts, investors and managers of companies as well as researchers conducting research in corporate finance area.

Originated as a production management philosophy, Lean Manufacturing has successfully transferred and implemented globally. Lean genealogy studies have been conducted, indicating the essential concept now evolves to Lean Management (LM), which is applicable to many branches of production and services management, viz quality and productivity, human resources, knowledge and technology, etc. Innovation has been made to ensure a smooth customization of knowledge and principles, tailored to each organization who is eager to implement this state-of-the-art management system. However, failures are becoming commonplace due to the lack of understanding the core values, and insufficient intensification of compensation for cultural differences. In this paper, cases of implementing LM across the Visegrád group (V4) and the ASEAN Free Trade Area (AFTA) from previous literature are taken into consideration. Factors that differentiate the characteristic of LM are brought to discussion. Therefore, the discovered gap between the two trade blocs urges the in-depth amendment and modification of employed concepts, tools, etc. A model is consequently elaborated, which aims at facilitate the managerial decision-making process regarding knowledge transfer of LM between V4 and AFTA, based on critical factors related to human, technology and culture, i.e. Labor cost, Manual requirement, Awareness, Continuous Improvement culture. This model can be used to predict the change should be made, or the criterion should be fulfilled to transfer the implementation and knowledge of LM effectively.

The transformation process towards a low-emission, green economy implies an increase in the demand for new professions and competences. Quality changes of jobs under the influence of the idea of sustainable development are both an opportunity and a challenge for both countries and individual regions. Green jobs are created as a result of the development of eco-innovation, new environmentally friendly technologies. The development of green jobs is particularly noticeable in the renewable energy sector. The article presents the results of empirical research in the field of analyzing the number of green jobs in the renewable energy sector in the Visegrad Group. In order to identify and determine the nature and changes in the impact of individual factors on the development of green jobs, panel regression was used – a model with fixed effects. The dependent variable was the relative number of green jobs per million inhabitants in 2000-2016.

Color is not a physical quantity of an object. It cannot be measured. We can only measure reflectance, i.e. the amount of light reflected for each wavelength. Nevertheless, we attach colors to the objects around us. A human observer perceives colors as being approximately constant irrespective of the illuminant which is used to illuminate the scene. Colors are a very important cue in everyday life. They can be used to recognize or distinguish different objects. Currently, we do not yet know how the brain arrives at a color constant or approximately color constant descriptor, i.e. what computational processing is actually performed by the brain. What we need is a computational description of color perception in particular and color vision in general. Only if we are able to write down a full computational theory of the visual system then we have understood how the visual system works. With this contribution, a computational model of color perception is presented. This model is much simpler compared to previous theories. It is able to compute a color constant descriptor even in the presence of spatially varying illuminants. According to this model, the cones respond approximately logarithmic to the irradiance entering the eye. Cells in V1 perform a change of the coordinate system such that colors are represented along a red-green, a blue-yellow and a black-white axis. Cells in V4 compute local space average color using a resistive grid. The resistive grid is formed by cells in V4. The left and right hemispheres are connected via the corpus callosum. A color constant descriptor which is presumably used for color based object recognition is computed by subtracting local space average color from the cone response within a rotated coordinate system.
