In terms of the volume of coffee is the second largest commodity traded in international trade and one of the most valuable globally traded agricultural commodities in human history. In addition, coffee is one of the most widely consumed beverages globally. In this way, it has a significant impact on millions of people worldwide, from farmers to consumers. The results show that the global coffee trade has grown steadily since 2000. In addition, the number of scientific publications in coffee is also growing exponentially. This article aims to collect and process the literature related to coffee. One of the essential scientific bibliographic databases, Scopus, was chosen and belonged to Elsevier. It contains more than 80 million records. This is one of the central archives in the literature that uses peer review to validate the research. A review of the literature revealed that there are few publications on the global coffee trade. Three historical stages of the coffee trade are identified and analyzed in the post-World War II period. The most important topics of these periods are dissected by the authors: fairtrade, coffee sustainability, coffee value chain, and various forms of regulation.

The traditional global food supply chains are not just complex, but they do not support the sustainability of agriculture. The business models with the greatest growth potential are those that would allow consumers to buy more directly from producers. Before COVID-19, these alternatives were not just popular but had a relatively high market share compared to post COVID-19 era. However, due to the pandemic and the changes in consumers’ purchasing behavior, the players of short food supply chains had to adapt to the new circumstances. This is why business model innovation is nowadays a priority, which means a substantial renewal of the value delivered to customers, and a significant transformation of the processes and activities of the company/network. The study aimed to examine the dynamic innovation through applied digital marketing solutions that could open up new sales channels and increase the competitiveness of the companies involved. Since Austria is one of the “greenest” countries, its consumers are interested in purchasing sustainably, so they strive to buy directly from the producers. This motivates the authors to use its representative sample to investigate how well adapted the Austrian direct sellers are to the unsteady circumstances. Based on a previous research framework, a principal component analysis was applied and the elements defined therein were the variables of non-hierarchical clustering. The used methods highlight the lack of online distribution and marketing of the farmer shops, which could multiply the harmful effects of the pandemic. The classification of the shops demonstrated the generally low share of innovative direct sellers. We conclude that in the new era, businesses that effectively apply open business innovation models will be able to compete in the market.

The success and the efficiency of e-Learning should be measured by a reliable method in order to use it effectively. Although, there are several studies about the success of e-Learning systems, only a few of them deal with the measurement of this success within the institutions. We made a questionnaire to evaluate the e-Learning application. The aim was to develop such questionnaire which is suitable to evaluate e-Learning quality. The basis of the e-Learning quality questions was a multi-dimensional model for assessing e-learning systems success (ELSS). The aim of the questionnaire were to compare the opinions of the students and the teachers and also to evaluate the Faculty of Economics and Business (FEB) of the University of Debrecen and the Corvinus University of Budapest (CUB) regarding the application of e-Learning. The role of the questionnaire for quality development is to give guidance for the FEB in implementing and using e-Learning. E-Learning in the CUB is applied under certain organized institutional circumstances. The e-Learning application of CUB works with an organization defined extended several faculties of the University, which can be a good example for FEB. We have used factor analysis and binominal logistic regression. We have examined whether the background variables manipulating the variables are possible to be developed on the basis of the answers. We used factor analysis to demonstrate this since it contracts the coherent factors into one common factor. Finally we used logistic regression to determine the importance of a given factor for the users of both faculties.

The aim of the AgroFE project is to play an important role in Agro-forestry trainings. Depending on the European countries, states or professional organizations and training actors try to reintroduce Agro forestry in the course of training and qualification in initial training and in adult education. The main objectives are to make a synthesis of needs and expectations, based on present the existing training actions and to set up a common framework; to build an innovative training system (contextualized, modularized trainings, use of ICT, professionals participation); to create a technical collaborative support for the implementation of the project with communication tools (information of partners and promotion) and for providing access to the resources and training services during and after the project (knowledge databank, interactive services). The user profiles (user groups) are Teachers, Professionals, Students, People with disabilities in professional situations, Knowledge feeders, Knowledge builders and aggregators. There are needs for handling many formats in the knowledge databank (Text in different file structures; Pictures or images; Audio and video files; Data and figures; Container format for exchange contents Pdf, html, Epub 3, etc.). More open source and exist tools and services have been evaluated, tested and used in creating the service architectures and finalize the system components. The Learning Management System, Collaborative Space, Videoconference Systems, Video Repository are implemented and used in the project. The architecture concept of the Knowledge Data Base and Services have been developed. The paper describes the results of the developments. The Moodle LMS system and videoconference servers (which can be used by videoconference equipment, user client software on desktop, notebook and smart-phone) is used for Collaborative working and learning environment. The Moodle (powerful, secure open source) learning and collaborative platform is used as project management, project assessments tools and e-learning / on-line learning. The videconference systems integrated with the Moodle system can demonstrate and show the path towards the near future service similar to the MOOC concept.

A hálózatokkal kapcsolatos kutatások módszertani alapját a gráfelmélet adja. A hálózatelemzés során nagy adatsokasággal dolgozunk és főként a szereplők szerepét és kapcsolatait vizsgáljuk, melyeket gráf hálózattal vizuálisan tudunk szemléltetni. A kapcsolati hálók elemzése egyre népszerűbbé válik a tudományos életben is. A szerzői kapcsolathálók nagy része néhány tekintélyes személy köré épül, akik egyfajta központi szereplőként irányítják saját hálózatukat, ezzel klikkeket hozva létre.
