Short supply chain means a supply chain involving a limited number of economic operators, committed to co-operation, local economic development, and close geographical and social relations between producers, processors, and consumers. It represents a relatively young concept in the Slovak Republic, that is underdeveloped at national level, but has received considerable attention at the international level. The objective of the paper is to evaluate the operation of a selected agricultural enterprise in a short food supply chain based on the example of the case study.

The artificial insemination (AI) represents the most effective biotechnological method used in horse breeding. Therefore, the optimization of already established protocols and their novelization are an important research topic globally with the one goal - to preserve and improve the quality of insemination doses and thus improve the fertility rate. The purpose of the study was to investigate the activity of Maca peruana and determine changes in physiological functions of stallion spermatozoa by adding a solution of Maca dissolved in DMSO and diluted with saline to concentrations 0, 2, 4 and 8% (CON, A, B, C, respectively). The samples were incubated at 37°C throughout the experiment and the measurements were performed in time intervals 0, 60 and 120 minutes. The quality of samples was evaluated by CASA and mitochondrial toxicity test. Motility and progressive motility of spermatozoa of stallions showed stimulative tendency in Maca treated samples especially in experimental group A that exhibited the highest percentages in all measured intervals. The mitochondrial toxicity test showed changes in Maca treated samples, whose survival was several percent higher than the control sample. In conclusion, the beneficial effect of Maca on spermatozoa has been partially confirmed but mainly when spermatozoa were treated with very low concentrations of additive. The study brings an attention to not widely used plant substance (Maca peruana) and offers numerous opportunities for further research concerned with male reproduction and AI in particular.

We are currently witnessing a sharp rise in prices, not only in Slovakia but throughout Europe. This price increase is caused by rising prices for many basic commodities on world markets, such as wheat, oil and natural gas. Energy prices, transport costs, as well as the prices of basic raw materials are rising, which must naturally be reflected in the increase in the prices of products intended for the final consumer. However, the prices of many products can also be affected by the efficiency of the supply chain that ensures their production. By clarifying all flows and relationships in the supply chain and optimizing its operation, we can reduce the price of the product. An SCM (supply chain management) application can be a useful tool to plan, record, evaluate and optimize the operation of a supply chain and facilitate mutual cooperation among the subjects that make it up. According to a survey, which we have done, there is not a single company using an SCM application in Slovakia today. The aim of this article is to point out the benefits and possibilities of such applications as one of the possible ways to mitigate the effects of inflation on the population.

The paper deals with the changes in online education, which became common practice during the COVID-19 pandemic at all levels of the education system. Another trend in the period was the hybrid education model used in the temporary reopening of schools. The management of schools and universities immediately introduced measures to ensure the continuity of education and its transition to the online environment and defined the rules for the implementation of work activities in the home environment, i.e. home office. The decisive factor in the optimal "setting" of new conditions of education and work is their digitization and wide application of information and communication technologies and Internet services. After two years, it can be stated that the pandemic "contributed" and accelerated the processes of digital transformation of classical education systems and traditional forms of work. Benefits of the period are from the perspective of the individual/society increasing the level of information literacy and digital competencies, increasing the use of online learning platforms and digital learning resources (content), new opportunities for self-development and self-education of individuals and shaping their digital competencies for living and working in society. On the other side can be observed negative effects of education and work in the online environment associated with long-term social distance of people in several areas of personal/working life. The author is a member of the working team for the creation distance learning methodologies at FEM and participates in the formulation of procedures and practical implementation of emergency distance learning (ERL) tools. For a comprehensive view of the issue of emergency remote learning, he used his pedagogical and work experience (teacher of IT subjects; administrator of ICT and IT support), but also the results of a controlled interview with participants in emergency remote learning (teachers/students FEM, their experiences, problems and attitudes) in comparison with domestic and foreign research and studies.

The Internet has become an integral part of modern people in the information society. It is also an important tool for digital communication. The digital communications market is constantly expanding with new multimedia services and applications. In this context, the aim of the article is to identify individual tools of digital communication at the NUTS II level in the conditions of the Slovak and Czech Republic in the period 2017-2021. The data were drawn from the Eurostat database. The analysis showed that the biggest share of the population uses the Internet for internet banking services in both countries. In the Czech Republic, 73% of the population use the Internet for this service and in Slovakia 58% of the population. On the contrary, the Internet is the least used for services related to the sale of goods and services. Only 10% of the population of the Czech Republic and 27% of the population of the Slovak Republic use this service. In the individual regions of Slovakia and the Czech Republic, the share of households connected to the Internet as well as the use of the Internet for formal and informal communication increased significantly in 2021 compared to 2017.

The main objective of this paper is to estimate the multiplier effect of financial instruments in Slovak agriculture. Slovakia intends to implement guarantee schemes as one type of financial instruments (FIs) in the CAP programming period 2023-2027. FIs are modern, transparent and efficient form of support to cover investment needs of farmers. They combine the experience of commercial banks with the CAP subsidies, which are limited. FIs should cover the financing gap, which arose in Slovakia due to suboptimal financing conditions for some types of farms. FIs can offer advantages for small and medium enterprises (SMEs), and farms, because they have similar difficulties with access to finance. In the first part of the paper, we evaluate the development of bank loans in Slovak agriculture over the period 2014-2020. Bank loans to farmers increased from 477,1 mil. EUR in 2014 to 900 mil. EUR in 2020. In the second part we describe the leverage effect of guarantees. Leverage effect is determined by multiplier, which depends on the guaranteed rate and guarantee cap rate. Based on these rates it is possible to determinate bank and guarantor’s shares on default risk. With a proposed allocation of 150 mil. EUR of FIs in form guarantees in Slovakia in 2023-2027(from CAP) and a multiplier of 5 it is possible to provide 750 mil. EUR in loans to farmers. Another 1 250 mil. EUR of bank loans could be provided to support agri-food sector. These loans will be supported by guarantees from Slovak state budget in volume 250 mil EUR. Use of guarantees is way, how to contribute to sustainability of farms and agri-food industry.

The aim of this paper is to provide an overview on the changing role of higher education on the local economic development of the regions of Hungary after the change of regime, with special focus on the rural areas. The level of qualification of the population has always been an important factor in economic development, thus the development of the human resource must be a key issue in development policies. The higher is the share of population with tertiary education, the higher is the potential for economic growth. As being lecturers in higher education for more decades, our aim was to see how the role and function of the higher education has changed over the years in Hungary and how important its role is nowadays by being a center for innovations, basis for spin-off and start-up businesses, by the establishment of regional research centers acting as knowledge-transfer hubs. We all know that SMEs, startups, businesses with innovative approach play a crucial role in the local economic development, not only in Hungary but in the whole European Union, so any measures targeting their development are inevitable, however, we need to see whether the human resource of the country at the moment is suitable for the establishment/development of such innovative enterprises. In this paper we examined the 18 counties located in the rural areas. We collected and analyzed the data for NUTS 2 regions and NUTS 3 level counties located in Hungary. Our aim was to see the tendency of the role of higher education in the development of rural areas.

Cornelian cherry (Cornus mas L.) is a naturally growing plant especially in Europe and Asia used mainly in traditional medicine in the past. At present, it is beginning to be given the importance again, as it can be an excellent source of bioactive substances with a high antioxidant activity. In this study, antioxidant capacity, total polyphenols, phenolic acids, flavonoids, anthocyanins, basic dry matter components and carbohydrates were investigated. The antioxidant activity was determined by DPPH method, the total polyphenols, phenolic acids, flavonoids, and anthocyanins were determined by spectrophotometric analyses. Analysis of selected bioactive substances showed that cornelian cherry is a rich source of polyphenols, which was reflected in its high antioxidant activity, especially in the stone due to significantly higher values (p < 0.001) of total antioxidant capacity, total polyphenols and total phenolic acid content when compared to the pulp. The stone of cornelian cherry also showed positive values of polyunsaturated fatty acids and carbohydrates content. This study contributes to the analysis of cornelian cherry, which can be used in the preparation of functional foods or in the medicine.

Bee bread is a product from the beehive which has unique properties and offers not only well absorbed nutrients such as fat, carbohydrates, and protein, due to the process of fermentation, but also whole spectrum of bioactive compounds. Bee products such as honey, bee venom, royal jelly is widely studied, but bee bread has not been well studied yet and there is a space for further experiments to study its impact. The present study was conducted to evaluate the effect on the growth performance of Japanese quails by adding bee bread into feeding mixture. Japanese quails (n = 80) were divided into four groups according to administered bee bread into feed mixture HYD 11, which was given ad libitum, as follows: P1 (n = 20) 2 g.kg -1 of bee bread, P2 (n = 20) 4 g.kg -1 , P3 (n = 20) 6 g.kg -1 , and the control without additives (n =20). The groups were kept under the same conditions. Data were collected from three weighing done on KERN PLE 4200-2N (Kern & Sohn, Germany) on the 1st day, when they were put into cages, then on the 28th day, and on the 56th day. A significant increase in weight (P ≤ 0.05) on 28 th day in group P1 compared with control group K was noticed. As a result of the research, we can conclude that bee bread has a significant (P ≤ 0.05) effect on elevating growth performance by addition 2 g.kg -1 of bee bread into feeding mixture. The effect of bee bread on growth performance shows positive impact, nevertheless, the results can be used for further examination.

As a result of the research, we can conclude that bee bread has a significant (P ≤ 0.05) effect on elevating growth performance by addition 2 g.kg -1 of bee bread into feeding mixture. The effect of bee bread on growth performance shows positive impact, nevertheless, the results can be used for further examination.","PeriodicalId":240144,"journal":{"name":"International Scientific Days 2022: Efficient Sustainable and Resilient Agriculture and Food Systems – the Interface of Science Politics and Practice.

Unfair trade practices have been applied by traders against consumers who, therefore, enjoy a strong legal protection. Legislation on the EU and also on the national level in Slovakia describes the nature of unfair trading practices that should be avoided in commercial transactions. This paper aims at developing the understanding of unfair trade practices in business-to-consumer relations by reviewing the relevant legislative framework and by providing an overview of types of unfair practices that are prohibited and practices that were subject to consumers’ claims.
