Grounds of changemanagement
257-267Views:607Organisations 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
172-180Views:178Biogas 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.

Statistical Evaluation of University Student’s Motivation and Personal Competency with Principal Component and Cluster Analysis
365-374Views:198The 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
124-129Views:91The 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
334-343Views:272Civil 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.

The Construction History and Photo Scanner Survey of the Minorite Church in Nyírbátor
53-66Views:69The medieval Minorite church of Nyírbátor suffered serious damages and became abandoned at the end of the 17th century. In the 18th century, the baroque reconstruction of the church began, and later a second period of Baroque modifications took place. After this, the church remained untouched for a long time. Then, in the 20th century once again renovations were deemed necessary, because of its poor condition at the time. During the 19th and until the end of the 20th century, several restoration works and archaeological excavations took place, which focused on certain aspects of the church. In this article, I would like to present a summary of the notes concerning the construction history of the church and the results and methods of the photo scanner survey I carried out.

Designing Aspects and Classification of Bearing Industry Box Handling Apparatus
325-334Views:95It has been an accepted tendency in the industrial practice since the last third of the 20th Century to decrease the living labour demand of the manufacturing processes. One of the main tools of it is the automation of production. In the design, the construction and the programming of the developed automata, the results of electronics, informatics and mechatronics can be used. All of the scientific fields mentioned above undergo intensive development. By the application of the results achieved in the design of the applications, the monotonous, dangerous and tiresome work not requiring expertise can be assigned to machines. In the longer run, the application of the automata is beneficial also in financial aspect, since the costs of living labour are continuously growing, while that of the mechatronic and technological devices show a rather decreasing tendency. Reliability is also an important aspect. It is well known for everyone that a well-designed and programmed automatic device performs its task without mistakes. If there is any objection or breakdown, on the basis of the currently valid safety technology rules, the machine stops, does not trigger any damage and after its repair, work can be continued.

Staying Employed and Employing Others: Leadership Styles and Management Strategies of Proprietors of Micro Enterprises in Developing Countries
408-419Views:204This study sought to find out the leadership style and management strategies of the proprietors of micro enterprises that have enabled them to stay in business this long and offering employment to several others in the midst of unfavourable economic conditions in developing countries. Management strategy and leadership style are complementary in pursuing organizational goal. Though, literature on the subject reveals that not much research has been done on the survival of micro business on the African’s continent regarding owners’ management strategies and the leadership style. We used mix methods in data collection and purposive samplings of thirty (30) micro enterprises’ proprietors were interviewed. The result reveals that owners of micro business practice multistrategies in their organizations. The Study found out that the Laissez Faire or Free Rein Leadership and the Bureaucratic Leadership were not practiced by any of the research participants. However, Authoritarian Leadership with strict instructions dominated Democratic Leadership and appeared to have been very effective and yielded result in most micro businesses.

Neural Network Based Enveloping Model of Agricultural Tyre
214-222Views:69The vibration properties of agricultural tractor’s tyres significantly influence its response in terms of the exposure of the human operator to mechanical vibrations, which is still one of the key problems in the design and exploitation of tractors. The behaviour of the tyre in this sense is significantly influenced by the mechanism ofgeometric filtering of the short-wavelength unevenness of the unprepared ground mostly encountered by tractor during in-field operations. Herein, this aspect of tyre behaviour was studied with tyre rolling quasistatically over singular obstacle. Based on experimental results, neural network based model of tyre enveloping behaviour was developed. Main model properties are high computational efficiency, simplicity regarding number of input quantities and absence of the need for explicit parametrization etc. Main shortcomings of modelling approach used are high developing effort, labour-intensive experimental preparations and lack of flexibility regarding tyre design and operating parameters

Volunteering in Sport
217-230Views:567The subject of our research was the examination of the sports ambition and its motivational background. Our aim was to examine the volunteer experience of young adults in volunteering. Our goal was also to analyze the areas in which sports are chosen most voluntarily and what motivates them in sport. The basis for our questionnaire research was the concept of volunteering "4 W" (who, what, where, why). The questionnaire was designed to answer these questions in relation to sports ambition. The data of the questionnaire completed by 371 young adults (mean age = 23.93, sd = 9.93) were analyzed using SPSS statistical software, where we calculated basic statistics (mean, standard deviation, median, mode) and Chi2 test. More than 75% of the respondents have already worked as volunteers. One of the most popular areas of volunteering was sport. The most frequented volunteering area was among schoolchildren and students as well as university sports among young people, after which the area of competition and recreational sports proved to be the most popular. The main motivation of young volunteer workers was the following, : „I had a good mood”, „I loved sport”, „teamwork”, „work experience”, „learning and skill development” and „career perspective”. Organizations, marketing and communication areas in the field of sporting events and sportsclubs volunteering were the most popular in the area where the respondents had experience. A significant difference was found in the field of organizing and marketing volunteering in sports events, 61% of Hungarians worked, while respondents from other countries were only 34.2% (p <0.05). In the field of communication, higher values of respondents from other countries (45.7%), compared with Hungarians (33.7%) (p <0.05).

Literature Overall of Fatigue Analysis Approaches of Vehicle Components Made of Rubber
130-140Views:149Generally, the most frequently used structural materials are metals which have high strength and stiffness. However, there are many cases when other important properties come to the front, as well as high deformation capacity with elastic behavior, high viscosity namely good damping effect. Due to its above mentioned properties, rubber is widely used in vehicle and automotive industry. Vehicle components made of rubber usually exhibit large deformations. Cyclic finite deformations generate temperature in hyperelastic materials. Furthermore it is necessary to take into consideration the effects of ambient temperature. The mechanical properties of rubber depend on temperature and temperature changes can accelerate chemical alteration processes which lead to the material deterioration and fatigue processes. Research on fatigue behavior and fatigue properties of rubber has a great significance for predicting fatigue life and improving durability of rubber products. There are several studies on the fatigue behavior of rubber-based materials, but there is less research in the fatigue life prediction considering the influence of temperature and temperature changes. First purpose of this paper is summarizing the influence of temperature and temperature changes on the fatigue behavior of rubber. The second purpose of this study is to provide an overview of the state of the art on the fatigue life prediction of rubber with primary focus on the different methods available for prediction of fatigue life under the influence of temperature and temperature changes.

Composition basics and analysis of visual language of the product
381-385Views:88The analysis of the visual language of the product demands deeper analysis of the user’s profile and built behavioral patterns. There is an existing group of factors that have relatively constant nature - gender differentiation, age differentiation, belongingness to specific group – social status, place in hierarchy, race, religion, people with special needs, etc. The analysis of the visual language of the product can be done by analyzing the basic arsenal of the composition - the means of composing form shaping: scale –related to the correct size of the products and their components; proportions –associated with organizing the form plastical and visual order of the whole and its parts; contrast - related to the shape of the product, semantical or bounded to past experience; color –bounded to both formal characteristics and plasticity, as well as to contrast and its meaningful designation; plastic of the form - linked to the proportions and scale, which determines not only the structural and formal characteristics of the products, but also the meaningful reading of the forms. The analysis of the individual composite devices is demonstrated by Ingo Maurer’s lighting fixtures.

Displacement: Translation and Rotation. Differences and Similarities in the Discrete and Continuous Models
104-124Views:120The motion (displacement) of the Euclidean space can be decomposed into translation and rotation. The two kinds of motion of the Euclidean space based on two structures of the Euclidean space: The first one is the topological structure, the second one is the idea of distance. The motion is such a (topological) map, that the distance of any two points remains the same. The bounded and closed domain of the Euclidean space is taken as a model of the rigid body. The bounded and closed domain of the Euclidean space is also taken as a model of the deformable solid body. The map – i.e. the displacement field – of the deformable solid body is continuous, but is not (necessarily) motion; the size and the shape of body can change. The material has atomic-molecular structure. In compliance with it, the material can be comprehended as a discrete system. In this case the elements of the material, as an atom, molecule, grain, can be comprehended as either material point, or rigid body. In the first case the kinematical freedom is the translation, in the latter case the translation and the rotation. In the paper we analyse how the kinematical behaviour of the discrete and continuous mechanical system can be characterise by translation and rotation. In the discrete system the two motions are independent variable. At the same time they characterise the movement of the body different way. For instance homogeneous local translation gives the global translation, but the homogeneous local rotation does not give the global rotation. To realise global rotation in a discrete system on one hand global rotation of the position of the discrete elements, on the other hand homogeneous local rotations of the discrete elements in harmony with global rotation are required. In the continuous system the two kinds of movement cannot be interpreted: a point cannot rotate, a rotation of surrounding of a point or direction can be interpreted. The kinematical characteristics, as the displacement (practically this is equal to translation) of (neighbourhood of) point, the rotation of surrounding of that point and the rotation of a direction went through that point are not independent variables: the translation of a point determines the rotation of the surrounding of that point as well as the rotation of a direction went through that point. With accordance this statement the displacement (practically translation) (field) as the only kinematical variable can be interpreted in the continuous medium.

„Return to the Countryside” – The Retention Possibility of the Sport
292-307Views:346Nowadays, one of the most interesting parts of sociology is the research of the rural areas’ specific features. Within these studies the rural areas ability for survival and to retain forms an important basis. A basic pillar of these, that the youth from these areas become sufficiently motivated to return to their rural homeland after finishing their studies and be able to redound the local social and economic development. Sadly, we experience the opposite of it. Young generations are fleeing to large cities and in medium or long term it leads to the decay of these involved settlements; in worst case scenario the results can be irreversible. In close relation with the aforementioned, we have to mention the specific behaviour of the local – rural – elite, which can be the source of further problems. In the course of our research, we wanted to investigate, that what is the reason that university students, who are studying in large cities don’t want to return or move to rural areas. Furthermore, we tried to give an inside view about their opinions of rural areas and the life in the countryside.
