Experiences of Establishing Up-To-Date On-Site Sampler Applications
210-241Views:74Spatial problems and spatial decisions are decisive in agricultural-environmental informatics systems and the solutions require systems that can collect, evaluate and display spatial data. The distinctive features of spatial informatics systems therefore have to be considered when establishing integrated spatial informatics systems.
However, the prepared spatial evaluations are not the only „added value” elements of a completed informatics system. The method of access can also speed up the work of participants and the whole system, making it more efficient with simple data-handling and the application of open standards. The significance of prepared database archives can also increase, since the accumulated data-assets are easy to utilize and become marketable. -
Conceptional Model of Regional Agricultural Water Management System
199-209Views:91Our study focuses on the water management improvement of the Hajdúsági-löszhát (loess ridge). The Hajdúsági-löszhát (loess ridge) is an intensive agricultural area. At the same time, the problem of increasing water demand is still not solved, so towards of safety production irrigation should be improved. To realise this should be known not even agricultural water demands but industrial and urban ones as well, thus a complex water management system is required to be worked out.
In the first part of the research, the water demand in the area is mapped, then a conceptional model of the Hajdúsági-löszhát’s (loess ridge’s) water management system is created. After collecting data the water management scenario is summarized in a real time model splitted into five periods.
During the research, the instruments of spatial informatics (GIS) are used to get acquainted with the variation of the hydrological parameters in space and time. To understand and simulate the different decision making processes and to choose the right decision alternative, a decision support system is created with the use of spatial informatics data.
In addition, considering the potentially right decision alternative, irrigation will be started in practice, an effect and after-effect inquiry will be made, and the results will be analysed, evaluated and summarized. Finally, a suggestion to the most adequate irrigation technology will be made. -
Basic Research for the Development of Fertiliser Spreaders
52-57Views:79The knowledge of the physical characteristics of fertiliser particles is essential for the constructors and operators of fertiliser distributors. Among physical characteristics, the most important are the frictional and aerodynamic properties for the description of particle movement. Adjustable angled slopes, shearing boxes and various rotating disks are used to identify frictional properties. We have developed a high precision shearing box with digital force measuring cells and a distance signaller (incremental transducer) that we use for slide tests efficiently. We measured the frictional characteristics of 6 different fertilisers: the inner coefficient of friction and the coefficient of friction on ten test surfaces most commonly used in machinery, and we specified the relationship between displacement, loading and the coefficient of friction. We can conclude that the material of the frictional surface significantly influences the force of friction.
However, our experience tells us that the shearing box is not suitable for the measurement of the inner friction, since the examined particles slide on the metal surface of the shearing box in a growing extent in the course of displacement, so it does not measure the real inner friction. Therefore, in our experiment we have developed rotating shearing equipment with a constant shearing surface to identify the inner friction. We tested the equipment with fertilisers and we identified the inner frictional characteristics of 6 different fertilisers. With the developed rotating shearing apparatus we could measure the real inner friction of the particles.
To identify the aerodynamic characteristics of granules, wind tunnels and free-fall tests are used. An elutriator have been developed for our investigation. We have used fertilisers for testing the measuring equipment and we have identified the aerodynamic characteristics of 6 different fertilisers. -
Development of a Decision Assisting Soil Information System in Agriculture
130-133Views:69Hungarian agriculture may be characterized by the industry-like, conventional farming of the past decades. This form of management concentrated exclusively on functions aimed at production. We have to decrease this disproportion, especially when joining to the EU, by reducing the intensive agricultural regions and adjusting to the goals of the 2000-2006 NAEP programmes, forming such an agricultural system which integrates the advantages of both environmental protection and complex agricultural systems based on rational foundations. Nevertheless it’s a rational decision to make the soil information system with an exact spatial informatics background as a foundation of agricultural system, because this promotes easy handling as well the connection to possible subsequent modules.

Interpretation of sustainability in the utilization of renewable energy sources
61-64Views:101The utilization of renewable energy sources (res) is crucial regarding to sustainable reconstruction of energy systems. The target is a balanced, sustainable development of Hungarian energy management considering equally the ecological, social and economic aspects. There are many different technologies of utilization of res varied by sources, conversion processes, size and products. The comparison of each technology and their sustainability assessment are required by the importance of efficient remodeling of energy infrastructure. The group of attributes was composed by numerous important parameters in the course of our analysis with the choice experiment (ce) methodology. The estimation of each attributes’ influence on the individual’s preferences and choices was possible by this method and the preferences of the statistical population was concluded. So thus the utility derived from each attribute was estimated. The result of the ce analysis for the population of experts is demonstrated in the current phase of our research.

Evaluation of IT-Investments
378-386Views:84An informatical innovation is essentially a private business in the life of a venture but the ability of evolution and adaptability of ventures is remarkable for the national economy too. This is why it is important to observe the economical effects of IT investments. The introduction of an information system – as in the cases of other investments – requires pre- and post-calculations for payback of fixed assest, thrift and profitability. The operation of an information system means not only one-off acquisition of instruments and intangible assets, but requires continuous development, version control and improvement of hardware in the sake of conservation. There is a high rate of depreciation of IT investments in Hungary, because such goods change too quickly, together with the economic environment. If the conservation of IT instrument value wanted one has to make new expansions continually. IT specialists have determined some indices, one of which is Total cost of Ownership, which is an important indicator for investment analysis. In practice, there are some other models and methods we can adopt in our analysis. In this paper, I collected several relevant and usable methods for pre analysis of IT projects. Management can adopt these models in his investment process to make sound decisions.

Examination of the presence and effect of udder edema in Holstein-Friesian cattle
125-130Views:105Mastitis is the most common disease of dairy cows and the most expensive in terms of treatment. For this reason, great emphasis must be placed on its prevention. Based on literature sources, it can be said that there is a positive correlation between the prevalence of udder edema and the occurrence of mastitis. Our studies were carried out in a dairy farm in Csongrád-Csanád county. So far we have collected data from 64 cows with udder edema. The severity of udder edema was evaluated on a scale of 0–3 points one week before calving and for 3 weeks after calving. We observed that udder edema occurred in 78% of the studied cows at the time of the first calving. After calving, the length and diameter of the four udder teats were examined. Both anterior and posterior teats were shortened in severely edematous cows. When examining the diameter of the teat, we found that, depending on the severity of the edema, the anterior and posterior udder teats were 2.5 and 1.6 and 1.6 and 1.5 mm thicker respectively than those of cows without edema.

Information and Communication Technologies in tourism
49-53Views:145Technological progress and tourism have gone hand in hand for years. Information communication technology (ICT) and tourism are two of the most dynamic motivators of the emerging global economy. Tourism can be considered as one of the most profitable sectors of the Hungarian economy, and in rural areas it is often the only successful economic activity.
Development of ICTs and the expansion of the Internet have changed dramatically in the past few decades. This process is noticeable in
Hungary, as well. Platform of tourism increasingly get to the Internet nowadays, which is vitally important because tourism is an information-intense industry. Therefore, it is critical to understand changes in technologies in order to maintain the crucial role of this sector in the Hungarian economy.
The aim of my study is to support the significance of tourism in Hungary and especially in the North Plain Region with the help of statistical data. Then, I try to show how ICTs appear in this sector and emphasize the role of these tools with some concrete examples. -
Strategic Steps in the Sheep and Goat Branches
61-68Views:122The balance of the sheep and goat branches can be summarised as follows:
If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
– the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
– the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
– the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
– the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
– the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
– the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable. -
e-services for the farmers
11-19Views:102Nowadays the different IT tools and use of the internet have appeared almost in every sectors of the economy, so it may give several benefits and help to the agricultural producers. In this article I give a brief overview about e-government and its’ opportunities, then I give a short description of a few important governmental and specialized administration on-line services which are provided to the farmers. According to many experts using of informatics may cause essential change in the operation of the administration because of the fact that the electronic administration may evolve. Generally speaking, today the egovernment services are already an indispensable device to the reformation of the public administration, the modification of services which suits to people's demands and the creation of the more adaptable, clearer public administration. The electronic
documents are free from formal errors which is either important for clients or offices. The cases can be arranged even from home in 24 hours of the day. The spread and success of the use of electronic services depend not only on the quality of services, but the IT readiness of the target audience is also very important factor. Unfortunately the affect of e-gap is bigger in case of the farmers. -
Movement of Particles in the Air
22-26Views:102The physical characteristics of particles (seeds and fertilisers) can strongly influence their movements both in seeding and spreading machines and in the air. It is therefore essential to study these particles when constructing such machines. In this respect the size, shape, coefficient of friction and aerodynamic resistance of particles are of great importance.
Due to their irregular shape, determining the size of particles is a troublesome process. A precise description of particles has to include several sizes and can be obtained from their screen size. Many physical properties of particles are relevant during movement in the air, but the aerodynamic resistance coefficient is the most important (Hofstee et al., 1990). Two types of wheat and four types of fertiliser particles were investigated (supported by the National Scientific Foundation OTKA, T-026482). An elutriator was designed and constructed (Csizmazia et al., 2000), in which an airflow is supplied by a centrifugal fan. Air velocity was measured with a thermal sensor. Particle sizes, mass and terminal air velocity were measured. The influence of the aerodynamic resistance coefficient on the particles’ motion is also discussed. -

Differences in Regional Development in the Northern Great Plain Region
170-180Views:120An important ambition of EU regional politics is the reduction of disparities. An important strategical objective of the Commission is to terminate underdevelopment and to ensure the development of the regions based on the principles of solidarity, equity and justice. The commission has dedicated forty percent of its common budget to achieve these goals. The differences in development are significantly influenced by the economic characteristics of the specific region, the quality and quantity of human resources, the accessibility of the region and factors influencing local quality of life.
The new spatial structure has been formed by the processes of the change of regime, the events of nineties and the economic renewal based onforeign capital investments parallel with crisis phenomenon. The economic, political and social consequences of the transformation have significantly transformed spatial structure and increased disparities. New disparities have formed, which strengthened due to the formation of east-west slopes and local crisis zones. The outstanding improvement of the capital resulted in great regional development differences, which can be detected when examining regional distribution of gross domestic product. The Eastern part of the country was most heavily affected by the collapse of heavy industry and agricultural mass production based on the Eastern markets.
It is of key importance for the region to strengthen regional competitiveness, which requires the application of consistent development-politics. Economic development is the most important, which can also draw the possibility of establishing welfare infrastructures. It is important to develop the processing industry, the supply networks and to ease the lack of capital it is also important to involve foreign capital. Developing agriculture plays an important role in transforming the structure of the economy. Since the conditions of the region, its traditions and long-term competitive advantages are favorable, thus can represent a greater ratio in the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting marketing, quality agricultural development and producer-retail cooperation. It is also highly important to promote development in transportation and informatics infrastructure and human resources.
In the future – based on the strength of the region – it is necessary to achieve such a consistent regional development politics, which by validating the principles of regional politics, serves the interest of utilizing regional development supports most efficiently and prevents the irreversible underdevelopment of the region and promotes fast development. -
Possibilities of Farm Management Decision Support
287-292Views:41Computer science has a major role in the decision-making process of farmers. In this process IT can be applied to virtually all phase: from infromation gathering to information processing. I am examining the position of informatics in the decision-making process. IT can be used in every single phases of the decision-making process. In my essay the useage of Internet and the possibilities it can provide play a significant role.After a brief description of the IT position of Hungarian agriculture I am introducing some programs, which can be used in the management’s decision-supporting system. Besides the Hungarian experiences the West European surveys also comfirm the application of Information Technology.

Regional Development Differences in Hungary and the Northern-Great Plain Region
62-71Views:116The most important endeavour of European Union’s regional policy is to moderate disparities. An emphasised strategic objective of member states, based on the principle of solidarity, fairness and justice, is to develop regions and almost forty percent of the common budget is devoted to achieving this objective.
Hungary, as a full EU member state, will get a new chance for underdeveloped regions, especially for the Eastern-Hungarian as well as the North Hungarian and North Plain Region.
The differences in development among the regions are significantly influenced by the economic characteristics of the specific region, quality and quantity of human resources, accessability of the region and other factors influencing local quality of life beside natural conditions.
The new spatial structure was formed by change of regime, processes of the nineties, primarily the economic renewal based on foreign capital investments and the crisis phenomena in parallel with these. The economic, political and social consequences of the transformation significantly changed spatial structure and increased disparities. New disparities formed which were further aggravated as a consequence due to the formation of the eastern-western slope and local crisis zones. As a result of the outstanding development of the capital, the long term differentiation of regional development differences can also be detected when examining the regional distribution of Hungarian gross domestic product. The collapse of heavy industry and agricultural mass production based on the eastern markets primarily affected the north-east counties in the eastern part of the country.
Strengthening regional competitiveness is of key importance for the region, which requires the application of consistent development policy. The most important is economic development which, if it operates well, also infers the possibility of establishing welfare infrastructures. Drawing in external sources to ease the significant lack of capital is important for the processing industry and the development of supplier networks. Agricultural development also plays an important role in transforming economic structure, since the characteristics of the region, its traditions and long term competitive advantages are favourable, therefore it is going to represent a higher ratio within the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting market accession, quality agricultural production and stimulating producer-retailer cooperation. The development of transportation and informatics infrastructure as well as human resource development plays a significantly important role in the development of the region.
In conclusion, the implementation of such a consistent regional development policy is required in the future, based on the strengths of the region, that serves the most efficient utilisation of regional development funds through the implementation of regional policy principles and prevents the irreversible decay of the region while promoting rapid development. -
An Efficient Method for Making an Educational Program
3-8Views:58Distance education, a new teaching method widely-spread in higher education nowadays, requires the extent use of multimedia self-study educational programs besides the traditional means and methods.
Experience shows that besides certain types of software like encyclopedias, dictionaries, language manuals etc. there is an ever growing demand for appropriate educational programs that can be tailor made, adapted or modified for various kinds of students.
These programs reflect the teacher’s approach to the subject and contain the relevant, up-to-date information.
Since they are used in a relatively limited circle, usually within a faculty of an institution or within a single subject area, it is crucially important to be able to produce them with as little energy and time as possible.
There is a PhD research program, aiming at creating a flexible multimedia framework, that can be a possible solution to the problem. This framework can be easily filled with different teaching materials compiled by certain teachers without advanced knowledge of informatics. The framework itself is carefully designed and guarantees high quality.
