Digitalization Process by Agricultural Companies, or the Results of a Questionnaire Survey
625-636Views:261The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

Indicators of environmental performance evaluation – theory and corporate case study
224-231Views:703In the last decades there was a change in the field of corporate performance evaluation. Performance management systems, indicator-based systems and new, intellectual capital-based evaluation systems have appeared. Finally new, wide range of corporate evaluating methods was born in theory and in practice too. It is also important to mention, that in a life of organizations there is an improvement in the activity in connection with sustainable development, and also in the usage of methods connecting to sustainable development. Therefore the evaluation in the dimensions of sustainability – in a case of environmental performance evaluation, or evaluation of corporate social responsibility – became more and more emphasised. We concentrate on the theory and practice of environmental performance evaluation. Summarize – based on definitions – the concept of environmental performance evaluation. We concentrate on peculiarities of environmental performance indicators – based on international standards and literature review; and also mention the characteristics of indicator systems. Based on theory, the practice is also important. Therefore we present a case study of a multinational company.

Innovation in Nonbusiness Organizations from a Conceptual Point of View
97-102Views:182The definitions of innovation have been transformed a lot over time since Schumpeter introduced his concept. Even recently one of the most prestigious innovation management references, the Oslo Manual have changed its concept. One rarely discussed aspect of the concept of innovation is that most of the definitions are referring to the business sector; only a few of them are referring to any kinds of organizations, including non-profit and governmental organizations. Any kind of organization must innovate sooner or later; therefore they have to learn how to manage innovation effectively and efficiently. That is why the broad type of definitions is recommended, involving not only for-profit organizations but non-profit and governmental organizations as well.

Human security issues of deep wells retraining
114-123Views:89Nowadays, in the world's energy production structure, fossil fuels dominate and at the same time cause a number of environmental problems. Comparing the use of conventional fossil fuels with geothermal energy, this kind of energy production is extremely beneficial, as there are no pollutants and a renewable energy source. Moreover, if we want to compare geothermal energy with other renewable energy sources (such as wind energy, solar energy, etc.), much of the benefits can also be attributed to geothermal energy becouse it is a stable energy source and the area requirement is low. Due to these extremely favorable properties, the study of the applicability of geothermal energy is gaining ground in renewable energy sources. In addition, it is well known that there are approximately 20 to 30 million abandoned oil wells in the world, plus sealed wells for other purposes, and the final number may be much larger. In the case of abandoned oil wells, the escaping residual oil may be a problem, which can lead to significant environmental problems. Taking these factors into account, research on the recyclability of abandoned wells for geothermal purposes becomes a target for more and more research topics around the world. It is interesting to note that a significant part of the publications are concerned with examining the technological potential of energy utilization, studying heat transport processes, and generating general, energetic or economical evaluations. A publication of a kind that would have evaluated the safety of recyclable abandoned wells in publishing databases was limited. It is therefore an important question that the abandoned wells, from the point of view of human security and environmental protection. How can they be reactive, how can the new technological elements be built up and how much human security factors of the newly created system are affected by the existing elements?

Management Practices from Christian Point of View
14-30Views:200Globalisation is a complex and worldwide process overarching historical times and continents. However the phenomenon brought efficiency and new opportunities to companies, providing practically free access to raw materials, labour and knowledge, it also caused negative effects like the degradation of the biosphere, greater social and economic inequality especially in the developing countries. There are some companies operating worldwide which have acquired great economic power and influence. and governments have only limited possibilities (if any) to regulate their operation. The expenses of profit maximisation are high, which are often ‘paid’ by the socialnatural environment (as externalities) and/or by humans. The aim of our study is to overview how current business relations could be formed to be more „human friendly”. The research is done from a Christian philosophy point of view, focusing on the employees as the major stakeholder group of the comanies. As part of the study some practical examples and Hungarian organisations related to this topic are introduced in order to highlight the relevance of the topic.

Simulation of BLDC Motor Drive Systems for Electric Vehicles Using Matlab Simulink
48-52Views:256The defining scientific developments of our time would not have been possible without the use of simulations. The aim of the research is to create a simulation of a BLDC motor. When creating a simulation, great emphasis must be placed on defining the purpose of the simulation. This basically determines the structure and complexity of the model. The model discussed here was created so that an optimization task could be defined more precisely by inserting it as a sub-model into a vehicle dynamics model. Scalability was another aspect, that is, to be able to increase the accuracy of the model with measured data in the future, as well as to be able to validate it. During the research, a BLDC motor efficiency map generation program was created, as well as an environment for testing the generated data. The created system gives researchers the opportunity to use a shape-correct efficiency model when simulating a BLDC motor even without measured data. This makes it possible to discover real relationships between model parameters when performing optimization.

Examination of road sections in Debrecen by noise mapping
287-295Views:90During the research, noise level calculations were performed for 13 numbered roads in and around Debrecen and a noise map analysis was conducted on the roads’ environment. The first examined year was 1995, the last was 2017. In the time interval, annual status was determined based on average daily traffic data. In addition to the road noise values calculated for each section, a noise map was prepared for each survey year. For the evaluation of the results a difference map of the highlighted periods was prepared. Typically, noise level increase from road sources was identified between 1995 and 2017 in a significant part of the studied area (southern and eastern parts of Debrecen and around the newly built roads). Stagnant noise level was diagnosed near the downtown of Debrecen and around the main road No. 4, furthermore in some places noise reduction was caused by the development of the road network (between Debrecen-Józsa and Hajdúböszörmény, between Debrecen and Látókép around road No, 33, and along roads No. 4808 and No. 4814) .

Company Valuation of an Entity Operating in International Accounting Environment
320-331Views:598Company and asset valuation plays a major role nowadays. Determining the company’s value is a key factor for management in appropriate decision making, and it is a necessary step for individuals who wish to invest and for investors. There are numerous models which utilize different methods for company valuation. In our study we based our valuation on the McKinsey model for a company in an international accounting environment. In the study we present the main attributes of the McKinley model, its structure, which includes the main steps of valuation. We put a special emphasis on the calculation of free cash flow, future balance sheets and profit and loss accounts anticipation as well as future turnover, which highly influences the changes of data in the future reports thus in the company value. The McKinsey model is a discounted cash flow model, in which the company value and the consequent future cash flow can be determined as present value.

Parametric Programming Applied to the Optimal Production Structure in Determining
375-389Views:138The agricultural planning often the question arises, how the different input (fertilizer, feed, irrigation, etc) from what to use on a production (land, animals) unit basis, and to what intensity. The input transformational efficiency experiments by setting analysis and evaluation. For example examined the nutrient replenishers fertilization experiments, the effect of nutritional values of the feed on the body weight gain, milk production in animal experiments. The input input efficiency to the external environment (weather, soil conditions, unexpected events), the technology used and the biological factors both influence. The farmer must be chosen in each sector, taking into account the magnitude of these inputs and environmental requirements. The economic optimum is usually trying to approach the sectoral level, which serves as the basis for future planning data. The mathematical programming models using relatively simply and quickly determine the optimal production structure. The models provide the specific resource requirements for, and the limitations of the objective function coefficients are calculated on the basis of sectoral. This becomes a deterministic model, and we can get the appropriate sectoral analyzes outstanding results of production structures. Therefore the relationships within sectors directly incorporate mathematical programming model and corporate interests placed above the interests of the industry to determine the intensity of the sectoral inputs. in their article a fertiliser application example, we present the production structure and the plant production sector fertiliser input of a time optimization, in which the fertilizer for specified sectoral relationships appear in the model objective function.
