  • The Role of Renewable Energy Sources in Energy Production and Use

    The role of renewable energies in energy management is growing both in the European Union and in Hungary. The use of renewable energy sources is already quite large (transport, heating, lighting, etc.) and it is advisable to deal with these energy sources in the year 2020. The use of energy from renewable sources can reduce greenhouse gas emissions and reduce dependency on the continuously problematic oil and gas market. A review of energy data over the last 10 years shows that renewable energy sources are playing an increasingly important role in the European Union. I support this finding by the fact that the share of energy from renewable sources in gross energy consumption has almost doubled in the last few years.

  • Grounds of changemanagement

    Organisations of the 21st century exist in a permanent change. Change management in business management deals with the analysis of directed and planned changes. However, it does not consider spontaneous changes.Change has been addressed in social science since the 1970s and is of growing importance. As in many cases adapting to the change is crucial for the organisations to survive. With the changeThese spontaneous changes are chaotic processes that are carried out without control. In this paper I present the evolution of changemanagement, and the most important questions of changes.

  • Submerged aquatic plant (Vallisneria spiralis and Egeria densa) utilisation as a biogas cleaner and feedstock of co-digestion

    Biogas was produced from sheep manure and two types of submerged aquatic plant (Vallisneria spiralis and Egeria densa). The gas cleaning was carried out by a water scrubber, where a significant part of CO2 and H2S can be separated from the gas. A part of water from the scrubber was circulated through an aquatic plant growth tank and the growth of used plants was examined. Addition of E. densa to sheep manure increased gas yield by 8% and the mixing of sheep manure and V. spiralis resulted in 21% increase in gas yield. With the used scrubber, 70-80 vol% methane content can be reached in the cleaned biogas, and the water from the scrubber (which contained dissolved CO2 and H2S) resulted in 56-87% increase in size as opposed to 12-44% increase in the control group.

  • Experimental Study Regarding The Influence Of Compliant Hinges Geometry In Mechanical Structures

    In this paper an experimental study will be carried out, on the influence of geometry, using different compliant mechanical couplings. In the first part of the paper will be presented the compliance of the couplings and a number of consecrated works on this theme will be quoted. The article continues with the case study made on three types of compliant joints. These joints and the mechanics that substitute them will be presented. Towards the end of the paper we explain the experimental method and its results. The final ideas concerning this work will be filled out by conclusions and research directions.

  • Statistical Evaluation of University Student’s Motivation and Personal Competency with Principal Component and Cluster Analysis

    The aim of the research is to do a statistical evaluation of agricultural and rural development engineer student’s motivation and personal competency. It sums up the late generation Y’s characteristics and challenges. To be a successful, graduated employee, not only the skill is needed but the personal competency as well. Altogether, 121 filled out questionnaires were collected from the students which were the prime source of the research. They had to evaluate influential factors to their motivation level and competence. The database was analyzed with descriptive statistic methods, principal component and cluster analysis. Studying the personal competency, five different factors were divided based on Belbin’s team roles and four clusters. The four clusters were established by the five factors. Analyzing the student’s educational motivation four different components were divided: the need of performance, social entertainment, the benefits of learning in the near future and the reach of the financial freedom. Based on the four components, generating clusters was not possible due to the significance level of the K-means cluster analysis because it was higher than 0,05 in every grouping variables.

  • Analysis of the Policy Background of Transport Related Use of Renewable Energy

    The EU energy policy prioritizes the following principles: sustainability, competitiveness and security of supply and addresses the reduction of greenhouse gas emissions as a priority. The related EU policy (including the White Paper on Transport) outlines these principles, identifies goals and opportunities for action. At company level methodological guidelines and standard procedures can be used to assess the carbon footprint of the organization, to generate efficiency goals and to prepare action plans. In the Hungarian policy framework, a comprehensive National Sustainable Development Framework Strategy defines the basic principles for the analysis of the sectorspecific or regional strategies. Sustainable Energy Action and Climate Plans (SECAPs) integrate energy and climate issues and include interventions and improvements for the better use of renewable energy sources in transport at municipal level. As a summary it can be stated that exploration of the policy background would needed to influence the use of renewable energy sources for transport and definition of the development goals can help economic organizations to transform their mobility patterns and reduce related carbon footprint.

  • The Landscape of Civil Society Organizations in the Economy of Kosovo

    Civil society organizations (CSOs) in the scientific literature have been studied broadly from various aspects such as cultural, political, social and economic. But as far as the last one is concerned, there is still a research gap because there is a lack of study about their contribution to economies under development, such as Kosovo, and which must be filled because of its importance. This paper tends to analyze the present situation of CSOs in Kosovo and their potential contribution to economic activity. Highlighting the activities, the structure and the place of these organizations in the economy will be the approach, in the beginning, to pave the way for further study of specific areas related to them. The methodology established contains analyses of secondary sources that are done by using data from the Ministry of Public Administration of Kosovo, Kosovar Index of Civil Society which is a regular report of the Kosovar Civil Society Foundation (KCSF), and other supplementary data. However, this will proceed after the scientific conceptual issues of CSOs and their place within the economy. Finally, the results show that civil society in Kosovo is very diverse with organizations in different sectors, and the economic activity sector consists of mostly agricultural NGOs.   In transition countries, CSOs are seen as an alternative that improves a particular sector. Thus far, there are over 10,000 organizations established in Kosovo, but relative studies suggest only 1000 to be active. Furthermore, their activity and contribution to economic development is little known so far, while the main problem of the economy remains unemployment.
