    In the domestic fish production, natural waters have yielded for several years about 7-8 thousand tons. This, from the point of view of outputs, considering the almost 130 thousand hectares of natural water, is rather low, it means approximately 55-60 kg/ha mixed fish.Although the various natural waters can differ significantly on the basis of yields, yet on the majority of the territories, the results were low. In the case of our extensive still waters and rivers, the reason can undoubtedly be found in the combined effect of the lack of the possibility of reproduction of the fish stock and the over-fishing. Fishery built on planning supposes the best possible knowledge in the given circum stances of the parameters of the water area and its fishstock. Lacking this knowledge, it is not possible to establish the optimal use fulness of the resources, what is more, the management can make faulty decisions – as a result of a lack of information -, which can risk the success of later activities.
    It is known that many factors have an impact on the success of the fishery, as well as some information in connection with the water area and the fish stock are necessary, the knowledge of which make it possible to manage the fishery in a planned way. One part of the information is available, while the other part is incomplete or not deep enough. The necessary data are dissimilar depending on their nature, can be obtained from different places, by different methods.
    As the first step for executing the field surveys and processing data, I developed a complex model, which contains in a unified system the steps of estimating the fishstock. I made the sampling on the basis of this. Part of the model is a fish faunistic survey, as well as a morphological survey of the water area. The information gained from these are important for making more accurate the system of devices of the samplings for stock estimation (duration, number of net-rows) and for assigning its place (places representing the best way the physical characteristics of the given water area). The major stages of stock-survey: A) faunistic survey, B) physical survey of the bed, and C) sampling with the help of gill-nets. This is followed by the evaluation by the computer module.
    The results of the research create a methodological and technical background for the fish faunistic and population biologic surveys still performed in different ways in our country, and by applying these methods together, all basic information about natural waters which help decision-making concerning fisheries can be obtaine deffectively.

    Expert systems are softwares that incorporate the experience of an expert and support decision makers by leading them through the thinking processes of an expert in the form of „if…then” rules. To use an expert system we have to work with knowledge expressed in a pre-determined form. To do so, we used a shell that can be purchased, and we acquired knowledge about the topic from experts through interviews and personal monitoring. Attributes that are non-measurable, such as many of the factors determining work-place organisation and revealing knowledge related to it, can be formed into words by using expert systems. The goal of the study was to present a suggested form of expert system model to help judge the level of work-place organisation.

  • On the Knowledge of University Students About the Strategies of National Sustainable Development

    The definition of sustainable development has a past which spans two decades. Today it is evident that the three pillars of sustainable development – environment, economy and society – have a strong correspondence and equally effect on every people. The UN’s Environment and Development Conference in 1992 declared the requirement in the document of Objectives for the XXI. century, that governments should prepare national sustainable development strategies. The World Conference of Sustainable Development in August 2002 made a stronger decision: „the states should make immediate steps forward … defining and preparing their national sustainable development, and for the purpose to start its realization until 2005”. Most of the countries fulfilled these requirements, and the Hungarian government promises to prepare its national strategy by the end of 2004.
    The aim of my study is to survey the knowledge of university students about the above mentioned process and generally about the topic of sustainable development. The selection of the target group is justified by the importance of young intelligentsia in the future. In order to examine their knowledge, I prepared a questionnaire and from the emerging primary data, my conclusion and statements have been deducted by a processing-analysing course, on the bases of which I made my suggestions.

  • The comparative evaluation of the preparedness and development of graduates

    The skill of dealing with people was given a special importance by the persons interviewed during my examination by means of questionnaires although most of the specialist works I
    consulted did not pay too much attention to this fact. When asked about the particular fields of further studies, only a small proportion of the respondents regarded the development of their
    personality important. I think to dissolve this paradox is necessary as without the development of personality it is impossible to improve interpersonal skills, that is one of the basic pillars of good performance at work. Regarding that it is the graduates who fill managerial posts, dealing with people belongs to one of their tasks.
    Among the respondents if the first degree were from a college and not from a university, the greatest proportion of those studying further would live in Heves and Borsod-Abaúj-Zemplén counties. However, this connection cannot be proved in Budapest. Individual motivation is the main drive of studying further after obtaining a degree in a greater and greater proportion.
    The graduates’ studying further is significantly directed to acquiring extra knowledge rather than a totally new profession and they get a deeper insight into the knowledge necessary for
    their profession driven by their own motivation.

  • The Misunderstood Role of Foreign Language Departments as Integrators of Knowledge Across Disciplines

    Special purpose language courses have always pushed the boundaries that set them apart from, for instance, courses offered in a business department. When we as foreign language teachers enter the special purpose language classroom and begin to explore such areas as ecology, agriculture, biology, mathematics or even law, we inevitably have had to immerse ourselves in those disciplines, in order to be effective. Foreign language departments, like those from any other field of academia, are continually developing courses with cross-disciplinary topics which challenge the competence of our staffs. However, my experience tells me that our ability as language teachers to integrate knowledge from across the disciplinary spectrum is misunderstood, mistrusted and under-exploited. This article explores this unused, and sometimes undiscovered, potential.

  • Review of the biology of plant psyllid (Cacopsylla pruni, Scopoli 1763), and its role in the spreading of European stone fruit yellows, ESFY-phytoplasma with Hungarian data

    The European stone fruit yellows (ESFY) phytoplasma disease caused by pathogen ’Ca. Phytoplasma prunorum’ induces serious damages in cherry, sour cherry, peach, and apricot orchards mostly in Europe. Its known vector is the plum psyllid (Cacopsylla pruni). Many articles report on the biology (morphology, taxonomy, life cycle etc.) and the method of transmission of the pathogen by the vector, and the possibilities of their control. This paper reviews our knowledge about the vector, and summarises the results of an inland research carried out in a northeastern Hungarian apricot orchards. Our goal was to show some important data for the farmers or anyone who is interested in this disease and its vector. And give some known method that we can protect our orchards against them to prevent the appearance of the disease. As the psyllid that became infected with the pathogen can hold its infectionous capacity during their lifetime, it is very important to have enough knowledge about their lifecycle, that we can determine the right time and method to control them. We also have to know how to identify them; therefore, this paper lists several important data which can be helpful. The most important keys of identification are their wing color, which dark borwn in the apex and brown is in the remaining part of the forewing. The length of the antennae is also an important factor, since other genuse’s species have longer antennae than twice the width of the head. C. pruni has as long antennae as twice the width of the head. They return to Prunus species in early spring and we have to protect our orhards in this period against them. We have to use preparations with a knock down effect on them to prevent the inoculation of the pathogen into the trees in our orchards.

    Aflatoxins due to their toxicity pose significant economic and human health threat; therefore, it is important to avoid this type of contamination in agricultural products. Until now significant aflatoxin contamination occurred mainly in foods of tropical and subtropical origin because the optimal growth of the producer Aspergillus species is between 32–38 ºC. Nowadays the aflatoxin contamination is becoming higher threat in Hungary, due to the imported products, the rising average temperature and the climatic changes. There is a significant knowledge on the genetic and environmental effectors of the aflatoxin production; however, it is remained a great problem to control mold contamination and toxin production in farming and stock-raising. Here we attempted to summarize the knowledge on aflatoxin production and attempts of the elimination.

  • Comparative studies to model bioavailability of pesticides in distinctive soil types

    Bioavailability of pesticides is determined by two major factors: soil characteristics and pesticides’ chemical feature. These factors result in a definite adsorption capability whose extent varies on a large scale. By revealing interactions between pesticides and soils it is of high interest to model bioavailability of widely used pesticides, as it is a key element in terms of prospective toxicological aspects. Our work signifies steps forward improving pesticide soil mobility prediction models as we created model systems representing correctly natural relations. Comparison of different solvent extraction methods proved to be an efficient tool to gain information on the bioavailability of some widely used pesticides as well as to model actual environmental processes.
    Comprehensive comparison has been made between different experimental methods by applying 5 extraction models showing diverse efficiency in extracting capability of pesticides. In some cases chloroform excelled in mobilizing pesticides from soil, however mostly application of humic acid solution as extraction model was found to be at least as efficient as methanol, chloroform or CaCl2-solution.
    Four chemically much different pesticide (simazine, acetochlor, chlorpyrifos and diuron) were applied to two soil types (both sandy and brown forest). The extracted amounts were determined by GC/MS technique. Adsorption coefficients (Kd) were also calculated for the examined samples.
    Obtained results for Kd indicated that chemical feature of pesticides seemed to be of utmost importance in terms of soil binding capability preceding the relevance of soil characteristics. Adsorption capability of chlorpyrifos proved to be the most pronounced preceding simazine and the least prone to bind to soil acetochlor and diuron

    Like many teachers of ESP in Hungarian higher education, I have for several years been spurred to track and investigate those interrelationships that exist between the expectations of the multicultural European job market of the 21st century and the linguistic literacy competencies required of those young graduates that are searching for jobs in such an environment. What specific knowledge or rather, what specific combination of knowledge, skills and cultural competencies do they need in order to succeed? Are we, language teachers aware of the responsibilities we have in preparing our students for such challenges? This paper publishes partial results of a national survey conducted in 2000. The investigations involved 120 teachers of ESP in higher education and 71 young graduates of technical universities or colleges with different profiles. The queries covered a wide range of issues of which we will only be examining one – from two perspectives, though – here: a.) The retrospective satisfaction of recent graduates with the language preparation they received and b.) The teachers’ assessment of the importance of the components of the preparation they provided.

  • GC-MS studies to map mechanistic aspects of photolytic decomposition of pesticides

    Transformation of pesticides in the environment is a highly complex process affected by different factors. Both biological and physical-chemical factors may play a role in the degradation, whose ratio depends on the actual environmental conditions.
    Our study aims to reveal specific details of photolytic degradation of pesticides as important soil contaminants. Significance of these studies is enhanced by the fact that pesticide decomposition may contribute to soil degradation, and have harmful biological effects by degrading to toxic products. The toxicity of the examined pesticides is well known, however very little information is available regarding their natural degradation processes, the quality, structure and biological impact of the degradation products.
    The photolytic degradation of frequently applied pesticides of distinctive types (acetochlor – acetanilide, simazine – triazine, chlorpyrifos – organophosphate, carbendazim – benzimidazole) was investigated. A special, immerseable UV-light source was applied in order to carry out photodegradation. The degradation processes were followed by thin layer chromatography (TLC) and mass spectrometry coupled with gas chromatography (GC/MS). EI mass spectrometry was used to identify the degradation species.
    Each of the studied pesticides underwent photolytic decomposition, and the detailed mechanism of photolytic transformation was established. At least four degradation species were detected and identified in each case. Loss of alkyl, alkyloxy, amino-alkyl and chloro groups might be regarded as typical decomposition patterns. Deamination occurred at the last stage of decomposition.

  • Stability and development of Transdanubian agricultural enterprises

    Personal fulfilment, financial security, flexibility, relationships, information, rules - these are all hallmarks of entrepreneurship. Furthermore, one more important factor should be added to the list, which enables satisfaction resulting from reliable income and self-fulfillment: this is openness. An open mind to changes, to novelties, and to the workforce is necessary. The central question of the present research is how to effectively develop Hungarian small and medium-sized agricultural enterprises, especially in the Transdanubian region, by utilizing these factors. In addition to production, institutional and price risks, agricultural enterprises, like other sectors, are also affected by massive labour shortages and resource-intensive development objectives. In the research, primary agricultural producers, micro, small and medium-sized enterprises were surveyed through questionnaire in the second and third quarters of 2019. Using the snowball method, both the development opportunities and the risks were mapped in this sector, mostly among growers. The research results show that there is a correlation between satisfaction and development and favorable workplace relationships. These correlations were presented by demonstrating the relationship between technological development, income satisfaction, stable job creation, and the need to try new developments. However, there seems to be an invisible boundary to development in the examined field, which may stem from uncertainty, and yet, it is important to maintain development and learning activity so that the right knowledge and know-how is available to the business when needed. Since the results show that there is a lack of openness to new technologies among the farmers in the studied region, and this may pose a problem in the future in terms of meeting the expectations of precision farming, it is recommended to focus on innovation in the agricultural sector in Hungary.

  • Will there be a horticultural triangle (cluster)? Thoughts about the reconstruction of the Hungarian horticulture between two European regions
    21-27

    The authors of this study seek the answer to the question how to develop, in the first decade or decades of the 21st century, the university-level
    horticultural scientific training, the horticultural innovation and the scientific co-operation between companies and universities in Debrecen and
    in the North Great Plain Region and – in a wider sense – in Hungary to a standard being competitive even in European terms. With the synthesis
    of the prospects of past, present and future, they drew the following conclusions. The reconstruction of agriculture, horticulture and food industry
    is a part of reforming Hungary's countryside. Horticulture, producing high added value, will be able to decisively contribute to the plan whereas
    the value presently produced in an agriculturally cultivated area of 1,000 euros/hectare can reach 2,000 to 3,000 euros in the next two decades.
    A necessary and indispensable precondition to achieving this is the strengthening of the innovation output of the Hungarian horticultural sector.
    Despite the numerous technical criticisms formulated in connection with the serious problems of Hungarian agricultural and horticultural
    scientific innovation, no progress has been made in this field for the past one and a half decade. The scientific research of this topic hardly
    continued or did not continue at all, the up-to-date surveys and in-depth analyses were missing. The objective, basic principles and tasks of the
    Act CXXXIV of 2004 (TTI) enacted concerning research-development and technological innovation are clear and progressive. The co-operation
    between the National Research Technology Office and the Hungarian Academy of Sciences, the setting up of the Innovation Fund are heartening
    opportunities. These – along with the new Higher Education Bill to be passed – may as well be suitable for restarting the Hungarian agricultural
    and horticultural scientific innovation. In our opinion, this requires a new, well-considered national agricultural programme, which can be
    conceived in the framework of the "Ferenc Entz National Horticultural Plan" proposed by us for horticulture. In the most eastern Hungarian
    university knowledge centre, at the University of Debrecen, the continuing of the horticultural scientific innovation strategy started in the last
    decade may be the focal point and generator of the development of the so-called "Hungarian Horticultural Triangle”, or "Hungarian
    Horticultural Cluster". This region comprises the Northern and Southern Great Plain Regions and the area between the Danube and Tisza
    Rivers. Here, about 70 to 75% of the total Hungarian horticultural commodity stock is produced. The objective of the HORT-INNOTECH
    DEBRECEN programme planned in 2004 by the University of Debrecen, Centre of Agricultural Science is to establish the horticultural scientific
    research-development and technological innovation structure and knowledge base of the Hungarian Horticultural Triangle / Hungarian
    Horticultural Cluster. In harmony with this, the objectives are to bring about competitive, new horticultural products, to improve the conditions
    of utilising them, to enhance the competitiveness of enterprises based on technological innovation, to make use of the research-development and
    innovation opportunities available in the regions in an efficient manner, to as full extent as possible, to encourage the creation of places of
    employment producing high added value in the field of horticulture, to improve the technical skills of those employed in horticultural researchdevelopment and to promote their enhanced recognition by the society.

  • Public opinion on the settlements’ environment and the use of renewable energy sources in the Micro-region of Gyöngyös

    This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’
    comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.
    These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.
    Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance the
    elaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)
    to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation also
    being impeded.
    The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of pollees
    opting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can be
    presumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. The
    overall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts of
    climate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies calling
    attention to the importance of raising environmental awareness and providing full information seems to be essential and should be
    implemented, through the media and education.

    After the relaunchment of the Lisbon strategy, the cohesion policy of the EU concentrates even stronger on the establishment of the knowledge based economy, on R&D activities and innovations. In the first chapter I demonstrate the funds division of the convergence and regional competitiveness targets in the financial perspective between 2007–2013. The first sheet shows unambiguously that the new member states from Middle-Eastern Europe and the Mediterranean countries spend their funds on convergence and cohesion issues. The situation is contrary in the highly developed Western-European countries, in the core regions, where decisive part of the funds are spent on competitiveness issues. In the second chapter of the study I present the Europe 2020 strategy of the EU, that is a crucial paradigm change in the European strategy-making. While the Lisbon strategy focused on the social cohesion of the European Union, the Europe 2020 strategy strives the fostering of the European competitiveness. In the third part of the study I make a comparison how the funds-allocation altered during the two financial perspectives.

    Nowadays, the socio-economic role and function of universities as well as their relationship with the industry, are more than ever in the focus of both the political and the academic spheres. The importance of knowledge and technology transfer is increasingly stressed in various economic development plans and strategies. The increased interest is due to the fact that universities are located at the crossroads of education, research and innovation, which might be crucial for the country's economic competitiveness. The commercialization of university research results is a well-defined task of technology transfer offices. Measuring the efficiency and successfulness of such offices is a difficult, but not impossible task. The present article aims to analyze the existing literature on measuring the efficiency of technology transfer activities and to introduce the most commonly used measuring methods of effective technology transfer. The article attempts to answer the question how to measure the efficiency of technology transfer by reviewing the available international literature and by analyzing secondary data.

  • Element content analyses in the Institute for Food Sciences, Quality Assurance and Microbiology

    The role of chemical elements to ensure and promote our health is undisputed. Some of them are essential for plants, animals and human, others can cause diseases. The major source of mineral constituents is food, drinking water has a minor contribution to it, so the knowledge of elemental intake through food is crucial and needs continuous monitoring and by this way it promotes the food quality assurance and dietetics.
    With the evolution of spectroscopic methods increasingly lower concentrations could be determined, so the elemental composition of a sample could be more precisely and fully described. Due to the results the gathered knowledge up to the present is supported and new observations can be done helping us to understand such complex systems as biological organisms are.
    The quality of a food is determined by the full process of its production, consequently it starts with agricultural production so elemental-analysis usually cover the whole soil – plant – (animal) – food chain, by this way the „Fork-to-Farm” precept is true in elemental analysis field also.
    The history of elemental analysis in the University of Debrecen, Centre for Agricultural and Applied Economic Sciences, Faculty of Agricultural and Food Sciences and Environmental Management, Institute of Food Processing, Quality Assurance and Microbiology goes back to 1980s when the so called Regional Measurement Central gave the background for research. The continuous deployment resulted in an obtain of an inductively coupled plasma atomic emission spectrometer (ICP-AES) in 1988, which extended the scope of examinations due to its excellent performance characteristics
    compared to flame atom absorption (FAAS) and flame emission spectrometers (FES). The instrumental park retain up to date correlate to the developing analytical techniques due to acquiring a newer ICPAES in 1998 and an inductively coupled plasma mass spectrometer in 2004 – which sensitivity is three order of magnitude better compared to ICP-AES. The Institute supports the work with its own ICP-AES and ICP-MS since 2011. 

  • Need for measurement of the innovation at Hungarian SMEs

    Competitiveness studies have shown that innovation could be breakout point for some economies, regions and enterprises. Knowledge acquisition, creation and exploitation of the knowledge base have been an essential element for economic growth. These knowledge-based economic processes come together with the innovation. Measurement of innovation by indicators has been playing a really emphatic role in making strategy whether it is national or EU planning.

    Enterprises have always tried to measure and quantify their innovation activities mostly through the results of their economic process. Companies have generally considered their products as part of the innovation. That was the reason that in most cases they only and exclusively focused on the finished product. Some of them was able to realize that details of the production process must be taken into account in order to the whole innovation activity could be measured.

    That is why I find it important to examine of what the innovativity of enterprises is made of, and in which way they can be measured.
    In addition I was looking for the answer to the questions that how much the measuring method allows you to compare enterprises for further examination.

    The development of measurement methods is an essential moment of the article. As it is compiled for me the most important aspect of innovation, according to the statistical document, the Oslo manual guides you through the measurement methods and operational processes They play a very important role in proving my hypothesis. Overall, our country’s innovation results show those areas where we have high endowments, and also those where are the weaknesses.

    Of course, systems and tools defined by the governing authorities of national economies will have the main role but the activity of the European Union will be the frame in the end, because without subsidies from the EU budget, national budget wouldn’t be enough to implement these aims.

    The Covid epidemic between the spring of 2020 and the summer of 2021 showed that there is an increasing demand for various forms of forest-related tourism. Number of visitors in forests broke records in certain places: 32 million visitor days were registered in 2020 in Pilisi Parkerdő Ltd. alone. In this article we present data originated from the automatic visitor counters placed on certain forest lookout towers. Processing the data, we can get an insight of the number and distribution of hikers in each period. As a result of the research, forest managers can learn more about the popular tourist destination, furthermore, knowledge is gained about the motivations and needs of forest tourism participants. Based on this, public welfare investments that meet real demands can be planned in a cost-effective manner. Ideally, the results achieved can bring satisfaction to all actors involved in forest tourism. On the demand (visitor) side, targeted and needs-tailored developments increase the experience factor of the time spent in the forest. On the supply (forestry) side, knowing the motivations makes the performance of public welfare tasks more efficient, which ultimately contributes to the improvement of the sector's image.

    Sustainability and multifunctionality look to be crucial points of the future of developed agriculture. Energy utilization of a part of the available biomass perfectly fits in these expectations. Bioethanol production allows for the substitution of the most expensive and most pollutable energy source, gasoline, by agricultural materials. This article contains a complex evaluation of economic characteristics of this method and calculations for the expectable economic effects of a would-be Hungarian bioethanol program. This essay includes the most important technological knowledge, a comparison between bioethanol and the competitive energy sources (gasoline, biodiesel, MTBE) and the most interesting elements of bioethanol programs operating in foreign countries. Introduced are which participants in the bioethanol chain have financial interests and counter-interests under present economic conditions in the spread of bioethanol by the enumerazation of macro- and micro-economic factors. The statements and consequences are based on my own calculatiosn so I am truly interested in any professional opinion.

    The paper deals with the soil biological research and its contribution to the changed cropping strategy and to the sustainable and environmentally friendly farming and management. The paper emphasizes the importance of biodiversity, as one of the most important ecological functions of soil. The organisms, populations and communities living in the soil play a key importance in the preservation of soil fertility. The most important research areas are presented dealing with in the last decades the national researchers and the challenges we face regarding the current soil biological problems. We have to prepare to examine the soil biological effectiveness of the more widely spread bio-preparations, bacterium preparations, and bioregulators. The prerequisites are the versatile knowledge of the biological state of soils and monitoring examination of the different effects soils had (including the mentioned preparations).

  • Evaluation of dry matter accumulation of maize (Zea mays L.) hybrids

    The increase of the grain yield of maize is closely correlated with its seasonal dry matter accumulation. Dry matter is accumulated into the grain yield during the grain filling period. The following maize hybrids were involved in the experiment: Armagnac FAO 490, Loupiac FAO 380 and Sushi FAO 340. In order to determine dry matter content, two samples per week were taken on the following days: 22nd, 25th, 28th, 31st August, 4th, 7th, 14th, 18th, 22nd, 25th, 29th September and 2nd, 6th, 9th, 13th October. In the course of sampling the weight of 100 grains from the middle section of 4 ears was measured in 4 replications. Dry matter content was determined after drying to constant weight in a drying cabinet at 60 °C. Harvesting was performed on 13th October 2017.

    The daily precipitation sum was determined by local measurements, while the daily radiation and temperature data were provided by the Meteorological Observatory Debrecen of the National Meteorological Service in Budapest. Among the agrometeorological parameters, an analysis was made of the precipitation during the growing season, effective heat sums during the vegetative and generative phase, and the water supplies. The daily heat sums were determined using the algorithm proposed.

    The amount of precipitation in the winter period before the 2017 growing season was 210 mm. The soil was saturated until its field capacity. The rather dry and warm March and April had a favourable effect, but there was no worthy amount of precipitation until May (51 mm) due to the condition of the dried seedbed. Sowing was performed on the 5th of May 2017 in a randomised small plot experiment. There was favourable precipitation and temperature during the growing season, thereby providing ideal conditions for maize development, growth and yield formation. There was near average amount of precipitation in each year. The total amount of precipitation in the summer period is 342 mm. Temperature was mostly above the average, but there was no long and extremely warm period.

    The Armagnac hybrid reached its highest dry matter mass 126 days after emergence. Physiological maturity was reached sooner (on the 119th day) in the case of Loupiac, and even sooner in the case of Sushi (116th day). The thousand grain weight of Sushi (which has the shortest ripening period) was 286 g at the time of physiological maturity, while that of Loupiac was 311 g. Compared to Sushi, Armagnac showed 12 g more dry matter accumulation (306 g). In the case of all three examined hybrids, physiological maturity was preceded by an intensive phase, when the dynamics of dry matter accumulation was rather quick. On average, Sushi gained 2.8 g dry matter per day between 103 days following emergence and physiological maturity, while the same values were 3.2 g for Armagnac and 3.3 g for Loupiac. The aim of the regression line slope is to predict the behavior of the dependent variable with the knowledge of the values and characteristics of the independent variables using the regression line equation. Furthermore, to determine how the location affected the dynamic of dry matter accumulation in the Armagnac, Loupiac and Sushi hybrids. In regression analysis, the coefficient of explanation showed that the effect of day in the Armagnac was 97%, in the Loupiac 94%, in the Sushi 90 %. The determination coefficient (R2) is useful in determing how the regression equation fits. But, as we have seen, the determination coefficient alone is not sufficient to verify the model’s accuracy, in addition to the determination coefficient (R2), the normality of the data or the residuals, the variance of the variables at different levels, the independence of the data relative to time and non-oblique. Observations are evaluated for the correctness of the fitted model.

    Dry matter values decreased evenly and slightly following physiological maturity. According to our research results, it was established that physiological maturity is followed by a moderate dry matter loss. Until harvesting, Armagnac lost 40 g of its thousand mass weight in 29 days, while the same value pairs were 69 g in 36 days for Loupiac and 29 g in 39 days for Sushi. Loupiac – which had the highest weight at the time of physiological maturity – lost the most of its dry weight; therefore, Armagnac and Sushi had higher values at the time of harvesting.

    The goal of research planning is to optimize human and material resources while maximizing efficiency. If there are databases that can be used as a substitute for own data collection, effective research can be facilitated by reallocating resources. In the case of environmental studies, the knowledge of the climatic conditions of the study period is known to be a key factor in research planning process.

     In the present study, the data of our meteorological station in our research area (known as “Szamárháti Tanya”, Kesznyéten, Hungary) was compared with the measurements of meteorological stations operated by the competent water authority. Stations were taken into the study within a 10 and 20 km radius over a period of 21 months, to determine which provided more relevant data from the area.

    During the evaluation of results, the relationship between the local and regional weather stations were determined, and deductions were made from the obtained results to support the decision which of the targeted investigations could be of greater benefit.

    One of the main economical problems of sheep breeding is that continual production is not possible due to the seasonality of animals. Today, genes, mutations that may develop aseasonality in sheep are extensively researched in order to make the establishment of populations capable of aseasonal estrus possible.
    According to the current knowledge, the GPR54 gene participates in the GnRH release from the hypothalamus, and thus in the alteration of the reproduction state of the organism. Our research is aimed to determine whether the GPR54 gene has allele variations that influence the proneness to aseasonal estrus in sheep in a different extent. Therefore, the GPR54 gene sequence of sheep is first examined.

    The summarizing data collection of our study has been carried out in the scope of the FP7-REGPOT-2010-1 ’UD_AGR_REPO’ project as a part of the cooperation with the University of Lincoln. The University of Lincoln is an important partner of the project, the knowledge transfer activities that have been carried jointly with them are multilateral. One of the most important cooperation areas is the analysis of rural areas, rurality itself, determination of breakout points, exploration of alternative income sources, diversification possibilities. Some part of the work of the University of Lincoln on the field of rural development is based on the assessment and documentation global similarities and differences of rural areas. Present study also contributes to that work, it has been prepared on the request of the University of Lincoln with the aim of providing insight into the special political and economic changes/processes that took place in Hungary, and through them into the structure and operation of the unique Hungarian rural areas.

    The study first positions the definition of rurality and rural areas into context on the basis of official EU and Hungarian legal classification. Then it covers the important agricultural nature of Hungary, which significantly determines the possibilities and properties of Hungarian rural areas. The further description of rural areas is completed by some historical summary, the introduction of ownership changes, detailed description of employment and income conditions and finally by the listing of breakout points of rural areas as a conclusion.

    With the development of computer-mediated communication, the definition of literacy has gained broader dimensions (Murray, 1991). The ability to use new technologies to access, adapt and make intelligent use of information and knowledge is by now viewed as an additional and essential component of literacy. Today’s interpretation of literacy (often referred to as “multiliteracy”) must incorporate the communication that takes place through a growing variety of text forms associated with information and multimedia technologies.
    Since it is fast becoming a basic instrument for building the literacies required for success in academic and workforce environments, used as a tool, information technology needs to become a critical component of student-centered English language education.
