Abstract: In the dairy sector, the operation of the various control systems operates at the strategic level in the same way as other industries, but at the level of the task control, they operate specifically way. The Balanced Scorecard is an excellent tool for measuring our strategic performance, but does not necessarily provide a clear feedback on causality and subsystems related to indicators. In our research, we highlight the deficiencies and the development possibilities of the balanced scorecard through the operation process and control system of a dairy farm operating in Hungary. The model will be further developed using the KPI-tree method, which will be illustrated in through an example of a causal relationship with a financial KPI.
Keywords: agribusiness, dairy sector, balance scorecard, control system, KPI-tree

Abstract: As more regulations to protect privacy and security for online interactions is carrying out, as more complications to perform these transactions is coming forward, affecting the intention to execute these interactions online especially for old people. This study aims to reveal the relation between intention to use high secured e-services with the age of user. This study finds that there is a positive relationship between the over-40 years online users’ ages and their retreating from completing online transactions due the complications of security and privacy procedures. Also, the study finds that 85% of people feel more comfortable to execute their transactions online with the high secure regulation, but from another perspective, 60% of persons between 40- 55 years old don’t prefer doing their transactions online due to the complication of transaction security procedures, where 92% of people over 65 are avoiding to do the financial transaction online and they need another person help to perform it more than 82% of times.
Keywords: E- services, online security, digital gap, 40 plus people, intention

Abstract: The Information Technology (IT) business ceaselessly endeavours to enhance regarding deploying products or offering services with the approach of new technology, and cloud computing is quickly moving in the promotion cycle because it will reshape the method of delivering services of data innovation. Decision-makers still have numerous worries that could drop the adoption of cloud computing. This paper will show a systematic literature review to investigate the present situation related to cloud computing adoption. This is done by analysing 25 studies published about cloud computing adoption. The results of this review describe the current situation regarding cloud computing adoption, it indicates that companies are facing critical problems before they decide to adopt cloud computing, it highlights the factors that affect cloud computing adoption and it shows the companies direction towards the innovative adoption process determined by technological, organizational and environmental contexts. Based on the findings, the paper provides a research agenda for the companies to investigate the terms of cloud computing adoption and its migration.
Keywords: Keywords: Cloud computing; Cloud adoption; Computing in developing countries; IT application; Technological innovation.

Abstract: The profitability of “mainstream” economic systems lies in outsourced external factors, which make it cheaper to waste resources than to track and eventually recover them. However, non-circular economic models, that is, without feedback, carry many risks. These include deficiencies in primary resources, including resource price volatility, declining supply chain efficiency, increasing bans on waste trading, declining costs of renewable energy sources, etc., and these unfavorable patterns can also be termed “linear risks”. Through the analysis of open and closed business models and the presentation of the value-creating processes of the ReSolve matrix, we want to demonstrate how modern IT systems and digital solutions can increase the efficient use of resources and reduce production risks.
Keywords: Keywords: business model; circular economy; value-creation; IT application; linear risk; circular value chain.

Abstract: The pollution caused power loss of solar modules can be reduced by using self-cleaning coatings. When applying these coatings, the basic question is how the coating itself effects on the power of the solar module. The recent paper deal with this. It examines power, reflection capability and power changes due to contamination and self-cleaning of 5 different coated solar modules and compares them with the measured values of an uncoated solar module. Based on the results of laboratory measurements, it can be stated that the effects of photocatalytic thin layer and lotus effect based coatings increase the power of the solar modules by average 2%. The effects of the same contamination reduced the power of all modules, but the power of the coated modules is higher. After spraying with rainwater, the examined coated solar modules operated at nearly 4% more power than the reference, uncoated solar module.
Keywords: photovoltaic, photocatalytic thin layer, lotus effect, reflection, contamination, power.

Abstract: The transformation of agricultural production systems is one of the pillars of today’s modern production structure. The use of digitized and big data systems and the integration of smart solutions are important for efficient business structures and environmental efficiency. This will make it possible to adapt production systems based on sustainability and economic efficiency criterias. All this can also be seen in the optimization of milk production systems, as the development of data collection systems, the systematization and analysis of the big data obtained are an important part of new business solutions. Technological development has made it possible to transform business systems using modern data collection and analysis methods. Efficient business solutions invest in technology-driven tracking of production parameters and enable flexible, immediate system development. This article provides an overview of the data collection and analysis options available through the digitization of dairy production systems, which can thus be used as a reference in subsequent system transformation and business transformation processes.
