Development Level of Settlements of the Statistical Subregion of Nagykálló
Published September 22, 2004

I have attempted to develop methods and applications for indices used to evaulate the development of settlements. At first stage the complex index applied by the Central Statistical Office (CSO) was differentiated according to economic, ecological and social aspects, and at the same time the system of indices was extended. As a result of these ...the ranking list of the exemined settlements has changed compared to the ranking based on the complex index applied by the CSO. There are significant differences particulary in the evaulation of the ecological development, however, in same cases ranking of economic and social development of settlements is also different. These analyses demonstrate that by using more indices the evaluation of development of settlement would be more objective, and by classifying according to the three functions of the country the countradictions would be more visible.

The Usage of New Multispectral Satellites in Agro-Environmental Protection
Published December 6, 2005

GIS, and especially remote sensing, offers great help in performing agro-environmental protection tasks. It can process a large amount of data to an arranged set of databases, and is also an excellent source of information. Moreover its keeps the geographical coordinates of all data during processing. The usage of remotely-sensed data is one of... the most up-to-date and effective ways to observe, analyze and understand the complex phenomena taking place in all the spheres of agricultural production (soil, water, air), and also to track and monitor the changes of different environmental parameters, as they constantly change in time and space. Several indices will be described, which can be derived from remote sensed data. Next, a relatively new hyperspectral satellite sensor (MODIS) will be introduced, as it can be a input data source in research performed in agri-environmental protection. Last, a new meteorological satellite (MSG-1) will be introduced, as its data are available for public usage, and it could be an important data source.

Spectral analysis of stress symptoms caused by apple powdery mildew (Podosphaera leucotricha
Published February 25, 2014

An orchard can be examined on the basis of spectral data, using methods with which the reflected radiation can be divided into a large number of (several hundreds) small spectral channel (some nm). Calculated on the basis of such hyperspectral data from different index numbers the water supply of foliage conditions can be well characterized....>

The research site is an intensive apple orchard, which located in University of Debrecen, Agricultural Sciences Centre, Farm and Regional Research Institute at Pallag. During my experiments the preliminary evaluation of spectral, non-invasive measurement method are carried out for detecting stress symptoms caused by Podosphaera leucotricha.

Based on the results narrow band greenness indices (NDVI705, mNDVI705, mSR705 and REP) can be used for determination of diseased canopy and for the detection of stress symptoms of Podosphaera leucotricha,. These statements can be utilized in precision plant protection systems, since it can be a basis for such integrated active sensors with LED or laser light source, measuring reflectance at the certain spectral range, which can facilitate real time status assessment of orchards and can control precision fungicide utilization.

Assessing of soil aggregate stability: the sand-correction and its relevance
Published October 20, 2009

Soil structure and changes in its quality caused by Maize stem (1), Wheat straw (2) and Maize stem & wheat straw (3) addition were assessed by three aggregate-stability indices. We observed that the NSI index formula proposed by Six et al. (2000) was nonsensitive to the changes in soil structure caused by the investigated organic matter add...ition. Furthermore it overestimates the aggregate-stability of the investigated silty sandy loam soil. Therefore we proposed a new modified NSI formula which is sensitive to the questionable treatments and that resulted in a more
realistic NSI data. The most sensitive index to differences of the investigated treatments were the Mean weight diameter (MWD) proposed by van Bavel (1953, in Kemper és Rosneau, 1986).

Evaluation of IT-Investments
Published December 6, 2005

An 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 invest...ments – 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.

The effect of the “Transcarpathia” Free Economic Belt on the investment activities of the region and its development of foreign trade relations
Published November 20, 2011

The article analyses the figures of foreign investments and their territorial distribution and their change due to the impact of the “Transcarpathia” Free Economic Belt. The article studies the consequences of the liquidation of the “Transcarpathia” Free Economic Belt and the issue of restoring allowances that formerly existed on its te...rritory.
The Free Economic Belt that was founded in 1998 and its customs and tax allowances invoked the settlement of affiliated firms of several world corporations, like the “Eurocar”, the “Yadzaki”, or the “Jabil”. However in 2005 the government of that time repealed all allowances granted by the “Transcarpathia” Free Economic Belt, and due to this the increasing dynamics of the amount of foreign stocks which was penetrating into the economy of Transcarpathia started to decrease. Many companies halted their work which went alongside with closing-down several thousands of workplaces. The working “Transcarpathia” Free Economic Belt had a positive effect on the social and economic indices of the region, so discussions regarding its restoration have already been started between the president of Ukraine and the governor of the region.

Regional Development Differences in Hungary and the Northern-Great Plain Region
Published March 4, 2005

The 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.

Characteristics of roe deer bot fly infection in the southern part of the Great Hungarian Plain
Published July 31, 2012

I am investigating the occurance of one of the diseases caused by parasites in plain roe deer populations, namely a botfly larvae, Cephenemyiastimulator, (Clark, 1815) ranged among the Oestridae family. Nasal botfly larvae are common roe deer parasites and are generally spread nationwide. The subject of the present survey is the processing of t...he data gained about roe deer bucks of the year 2009 and their infestation indices. I investigated botfly larvae in 90 bucks’ nasal and pharyngeal cavity. We have found botfly larva in 18.9% of the examined bucks (prevalence), this means 17 infected specimen. I collected 218 pieces of larvae from the samples, with a 12.8 pieces average intensity. In my investigations prevalence was lower and mean intensity was higher than in previous Hungarian researches. This was manifested both in my overall data, and in our examinations by the different age groups.

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">In an agricultural field or horticultural plantation, weeds compete with cultivated plants for water and nutrients. The transpirated water by the weeds is needed to be replaced, which saddles surplus costs on the farmer, which could reduce the profitability of crop production. The aim of the precision plant protection system is to protect cultivated plants by applying site-specific technologies and optimized herbicides combination and methods, without environmental damage. The first step of precision weed control is the scouting for weeds. Traditional and modern (passive and active remote sensing) weed surveying technologies are available to detect weeds. The examination was carried out in an intensive apple orchard with drip irrigation system, protected by hail net of the Study and Regional Research Farm of the University of Debrecen near Pallag. The spectral-based weed detection was worked out by the Tetracam ADC broadband multispectral camera and the GreenSeeker 505 vegetation indexmeter. A strong correlation observed between vegetation indices and weed coverage. Based on the collected data, weed maps are created in appropriate software environment, thus the spatial distributions of the weeds are determined. The species level discrimination and the recognition of weed structural parameters were executed based on the 3D point cloud data by Leica ScanStation C10 laser scanner.

The aggregate stability of the soil in respect to the uniform aggregate stability indicator
Published July 16, 2007

Soil structure and its quality are fundamental properties because they control many processes in soils. Tillage, crop and other factors influence soil structure. Efficient protection of it needs indication of changes in soil structure. A new Normalized Stability Index proposed by Six et al. (2000) tries to evaluate these changes, which was comp...ared with some former used indices. The most common method (wet sieving) was modified to reduce the confounding effects of different particle size distribution of different soil types and method used to the investigation. Changes in soil structure caused by tillage and crop management therefore have been made quantitative and comparable. In this paper, we review the new method and Normalized Stability Index proposed by Six et al. (2000) and present the results of our investigations.

Changes in the Quality Parameters of Wheat Samples of 16% Moisture Content during Storage
Published May 11, 2003

We have carried out storage experiments with wheat varieties Magvas, Fatima, Mv Emma and Mv Pálma from the 2001 growth year. During the first half of the experiments quality parameters, such as changes in moisture, protein and gluten contents as well as pharinograph readings, falling numbers and sedimentation indices were analysed and tested a...t an average initial moisture content of 13%.
The findings in the changes in the quality parameters of different wheat varieties with 13% moisture content as a function of storage time duration were published in an earlier paper of mine (12/04/2002).
This paper wishes to give an account of the second part of the storage test when the moisture contents of the different varieties were raised to 16% and the changes in the quality parameters were monitored for seven weeks. The findings show that contrary to what had been experienced in the first half of the trial, there were no changes in the protein contents, pharinograph readings, water uptake or Zeleny counts and falling numbers showed decreases with each of the varieties tested.

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The interspecific ’hybrid striped bass’ is the result of cross breeding. Their offspring have got good chances of growth and tolerate extreme water temperatures and the content of dissolute oxygen more than their parents. Furthermore, they are more resistant to diseases. Therefore, the hybrid is perfectly suitable for intensive fishery production.

Our experiment lasted for seven weeks. We analysed the indices of growth and production of the hybrid as the consequence of nurturing them with two feeds of high nutritive value during this period. We examined the content of fat and of fatty acids in the flesh of these fish. There were no considerable differences in terms of weight gain, feed conversion ratio and uneven growth between the two groups, while survival was less likely among the the fish which had consumed more fat. We demonstrated, examining the flesh of the individuals which had consumed feed containing lower fat content, that it was fattier and contained more dry matter than those that had been fed of higher fat content. Besides, the content of omega-3 and omega-6 fatty acids was higher in the fish that had consumed less lipids.

Consumption tendencies of foods of animal origin in Hungary
Published September 2, 2009

One of the most important indices of the population's food consumption are the quantities of the consumed foods expressed in a natural measure. In the course of my examination from the 1980 years I examined how our dietary habits changed. I was able to demonstrate it by the time series examination well, in which years and in a what kind of meas...ure these consumer changes occurred. The trend analysis was in it onto my help, that let me be allowed to depict his beat as the changes of the food consumption visual.
In his totality the Hungarian population nutritional and from his consumer customs we may relate that the present nourishment increases it unambiguous the diet pendant the risk of illnesses, furthers their development, aggravates their effect, and contributes to the population's adverse health conditions powerful.
It was over in some years, in a decade on a unfortunate manner, we lost the natural instinct of the selection of the food in a considerable part. Our diet fundamental the narrower and the customs of wider environment, his rules, the social values, beliefs define it. Because of this to feed it is necessary to study it.
The changed and the health-conscious nourishment would be  important for him herding back into a upturned dietary habit correct bed with a wide circle recognizing him with the population, his role could be big for the healthy, or functional foods. The nourishment gives his pleasure likewise while we take over healthy foods.
The recognition of the changes of the demand and accompanying him with attention could be the domestic food producers' fundamental interests. The consumer types and the market segments should be mapped, that they suitable marketing a strategy can be aimed at it, and into the direction of the healthy nutrition to push away, and would be need onto an efficient informative campaign, onto an advertisement message formulated well, onto the making aware of this, that let the advertisement supply an educational function in one.
