Three experiments with dairy cows were conducted in an air-conditioned stable under controlled conditions. The objective of the study was to determine the effect of the regulated ionic microclimate on the emission of dust particles (aerosol) up to the diameter of 10 μm (PM₁₀). Four dairy cows were housed in common straw-bedded boxes and the stable was equipped with a vacuum ventilation system. To regulate the ionic microclimate, the apparatus Agri 1 000 (maximum voltage 7 kV, current 25 μA) was used. Thus the airborne dust concentration in the stable (42-132 μg/m³) was reduced by 12.7-26.2%. In experiments B and C statistical significance P ≤ 0.05 was reached. The emissive flow from the stable was decreased from 7.41-8.63 mg/h to 5.30-6.55 mg/h per one animal, i.e. by 24.1-31.3%. Owing to ionisation the ratio of n⁺ to n^- ions was changed. A unipolarity coefficient (P) was changed from 1.65-1.93 to 0.82-0.89, i.e. superiority of n^- ions.

An expert estimate of the weight of emissions produced in agriculture has been up to now made only through a final counting to the total REZZO 4 emission balance in the category of "other mobile sources" The existing situation is however unbearable since a proper methodology to determine the production of emissions in agriculture, i.e. in the department with a considerable consumption of fossil fuels, is still missing. The solution consists in a more precise specification of the weight of generated limited pollutants (CO, NO_x, SO₂, PM and VOC including CO₂) in the department of agriculture on the basis of the measured annual consumption of fuels in agriculture and with using the emission factors of fuels. Calculated results are compared with the original values finally counted for the REZZO 4 category of "other mobile sources" in 2000 and 2001 (Adamec 2002; Adamec et el. 2003). The calculation revealed that the weight production of individual pollutants in 2000 and 2001 reached only 28% and 27% for CO, 52% and 50% for NO_x, 69% and 66% for SO₂, 87% and 83% for PM, and 26% and 24% for VOC of the original estimates with final counts and was therefore much lower. The share of agriculture in the weight production of emissions from mobile sources in 2000 and 2001 was 3.1% and 3.1% for CO, 11.5% and 11.5% for NO_x, 19.8% and 18.8% for SO₂, 38.3% and 34.6% for PM, and 3.5% and 3.6% for VOC. The development of weight production for individual pollutants in the period from 1995-2005 is expressed by means of regression equations. Coefficients of reliability indicate that the measure of reliability of the interval determined by calculation is much higher than that of the reliability interval determined by values estimated through final counting that appear incidental. There are increasing efforts today focused on the replacement of diesel oil as a traditional fossil fuel in agriculture with biodiesel oil as a more environment-friendly fuel. The second part of results includes a monitoring of the impact of biodiesel oil emissions in cases where diesel oil was replaced by this ecological fuel in agriculture in the period from 2000-2005. It follows from the analysis that the weight production of pollutants in 2000-2005 would have been reduced by 4% in CO, by 28% in SO₂, by 52% in PM and by 4% in VOC while an increase by 20% and 32% would have been recorded in CO₂ and NO_x, respectively. Regression equations are used to express the development of the weight production of individual diesel oil and biodiesel oil pollutants in the period from 2000-2005. Reliability coefficients that are of constant character indicate that the development of the weight of pollutants from diesel oil replicates the development of biodiesel oil pollutants. The significance of achieved results consists in the provision of a more accurate general balance of emissions from one of so called other mobile sources in Czech Republic (apart from the department of transport), thus contributing among other things to a more accurate expression of the total weight of emission production within REZZO 4.

The study deals with the influence of the structure, texture and dynamics of a spruce-beech primeval forest on the bird community in Skalná Alpa National Nature Reserve in the Veľká Fatra Mts. (West Carpathians, Slovakia) in the years 1982-2002. The abundance of Norway spruce (Picea excelsa Lam.) was highest both in the optimum and decomposition stage. In the growth stage the number of Norway spruce (Picea excelsa Lam.) trees was quite low. The texture of spruce-beech virgin forest was very variable. Percentage ratios of individual stages on the area of 42.16 ha were as follows: growth stage 38.3%, optimum stage 20.1% and decomposition stage 41.6%. Altogether 46 bird species were represented in the bird community during the spring season. Mean total density was 85.8 ind/10 ha. The bird community consisted of 52 species in the summer season, 45 in the autumn migration season, 34 in the winter season, and of 47 in the spring migration season. The highest density was found in the bird community during the autumn migration season (109.8 ind/10 ha), the lowest in the winter season (24.6 ind/10 ha). During the spring migration season, both the spectrum of bird species and total density of bird community increased by the number of migratory species that came back from winter habitats.

Soil infiltration capacity is one of the key factors in the soil protection against unfavourable effects of water erosion. The purpose of its measuring was to compare and evaluate the changes of the soil physical properties and of water infiltration into soil caused by different intensity of soil cultivation at two individual sites. The ploughing (PL), shallow tillage (ST), and direct drilling (NT) effects on the soil physical properties, water infiltration into soil, and soil surface coverage with the crop residua under the soil condition loamy Haplic Luvisol, with long-term growing of maize (Zea mays L.) - Agroservis, 1^st Agricultural, a.s., Višňové - and clay soil of Calcic Chernozem (Cooperative farm Klapý), were compared. Soil bulk density values in the variant with ploughing showed in the depth up to 0.20 m considerably lower values as compared with the variants shallow tillage and direct drilling. Nevertheless, in the subsoil layer the bulk density of soil in the variant with ploughing increased in comparison with other variants. The results were also confirmed by the cone index values. At the plots in Višňové the infiltration was evaluated utilising the double ring infiltrometer, and by means of the coloured water infiltration. The results revealed significant differences in the water infiltration rate at various stages of the soil loosening. The highest average values were recorded for ploughing (1.00 dm³/min). The lowest values were found for the shallow soil tillage (0.18 dm³/min). The variant with direct drilling showed values of 0.53 dm³/min. The coloured water infiltration evaluation showed a different character of water flow in soil. The variant with ploughing showed water saturation in the top layer, the variants with reduced tillage were characterised by vertical macropores and crack effects with the water drain into deeper layers. Ploughing proved its advantage for the short-term rainfall retention. Similar results were also brought in the evaluation on the plot with clay soil (Klapý). The loosening effect was evident during coloured water infiltration in the period of snow thawing. The loosed soil layer showed a significantly higher soil water holding capacity as compared with variants with reduced soil tillage. The result showed major differences in the water infiltration rate into soil and different characters of water infiltration into soil at different soil tillage.

The paper presents the results of a regional analysis of climate change impacts on Norway spruce growth in the north-western part of Slovakia(Orava region). Radial increment was determined from nine X-tree sample plots established in the forests of natural character in the region. The analysis of PTT radial increment was done on tree disks cut from a height of 1.3 m by measurements of four perpendicular directions corresponding to the cardinal points. It was derived from the tree-ring width measured at breast height (1.3 m) while all the basic principles of tree-ring analyses were observed (transport and borehole treatment, measurements with digital positiometer to the nearest 0.01 mm, synchronisation of the tree-ring diagrams). A dendroclimatic model belongs to the category of empirical models based on the statistical evaluation of empirically derived dependences between the time series of tree-ring parameters and the monthly climatic characteristics. This statistical evaluation is based on a multiple linear regression model. Climatic models were used as basic tools for climatic change prediction. There is a scenario coming from the GCM category, which is derived from the models of Canadian Centre for Climate Modelling and Analysis in Victoria (British Columbia, Canada), used for a solution of this task. It is the latest connected model from the second generation designated CCCM 2000. For the purpose of this study the area averages were modified for the meteorological station Oravská Polhora with the 1951-1980 reference period. The modification includes two climatic characteristics, total monthly precipitation and monthly temperature means. The frequency analysis indicates that 24.4% of trees would react to the assumed climatic change negatively, i.e. by decreasing the increment, and 75.6% of trees would react positively. Most of the reactions are moderately positive. It is to conclude that 14.6% of trees will react to a climatic change significantly in a negative way, the reactions of 34.1% trees are considered to be unchanged and 51.3% of trees should react to the assumed climatic change positively (P = 0.95). It results from the analysis of the climatic change impact that the highest effect on stands situated on the upper forest limit can be expected.

We explored the ecological conditions, which influence the female Melolontha hippocastani F. in their selection of the locality for laying eggs. In the region of mass outbreak of M. hippocastani in the south-eastern part of the Czech Republic in selected experimental sample plots including 1 to 8 year-old forest plantations we explored the extent of losses caused by white grub feeding and the relation between the extent of the damage and the individual characteristics of the experimental plots. The relation between the extent of the damage and the method of establishment of the stands and degree of weed infestation at the time of swarming was evaluated statistically. The daily temperatures at the time of M. hippocastani swarming were recorded by means of automatic meteorological stations. A light trap was used to monitor the course of swarming.

Emmer and spelt are two hulled wheats that were widely grown in Spain until the latter 1960s. Twenty-nine emmer and twenty-six spelt lines obtained from Spanish accessions of these hulled wheats were analysed for quality traits and endosperm storage protein composition. The results showed a wide range of variability in these traits. Likewise, a certain association between some alleles of these proteins and the SDS-sedimentation volume has been detected.

The objective of this paper is to evaluate the contents of CF, NDF, ADF and ergosterol in the forage of Fistulolium, Dactylis glomerata and Arrhenatherum elatius from stands harvested at the end of the growing season. The contents of CF, NDF and ADF were analysed using the ANKOM Fibre Analyzer instrument. The ergosterol content was analysed by the HPLC method. The lowest CF content was in the Festulolium forage matter (26.8%). Conversely, the highest content was in the Arrhenatherum elatius forage (30.2%). The CF content gradually increased during autumn from 28.0% to 29.4%. Likewise, the NDF and ADF contents were lowest in Festulolium (58.3% and 32.3%, respectively). The highest NDF content was in Arrhenatherum elatius (60.5%). The ADF contents in Arrhenatherum elatius and Dactylis glomerata were comparable (35.9% and 35.1%, respectively). The NDF content increased during autumn from 56.4% to 62.0% and ADF content from 32.8% to 36.4%. The ergosterol content suggests a lower infestation of the Festulolium forage by fungi. While this content in the Festulolium forage was 94.9 mg/kg of dry matter (DM), in the Dactylis glomerata forage it was 136.7 mg/kg DM and in the Arrhenatherum elatius forage 139.9 mg/kg DM. Forage samples taken in December contained ergosterol on a level of 248.6 mg/kg DM. The species under study and the time of use in autumn exhibited a statistically highly significant effect (P < 0.01) on the contents of CF, NDF, ADF and ergosterol in the forage matter.

The main aim of this work was to compare the results of the water storages obtained in the experimental basins in the Jizerské hory Mountains before the time of snowmelt with the total outflows, which were measured in the hydrological stations during the snowmelt period in two winter seasons with extraordinary snow depths (2005 and 2006). The snow water equivalent (measured in weekly steps), daily precipitation amount, and runoff in hourly values were the input data; the calculated runoff coefficients were the output values. The runoff coefficients from the snowmelt periods of 2005 and 2006 were compared in the Uhlířská and the Jezdecká Basins. The runoff coefficient in the Uhlířská Basin increased in 2006 from 0.636 to 0.688 (increase by 4%) and in the Jezdecká Basin it increased in 2006 from 0.660 to 0.749 (increase by 9%). It may have been the result of a bigger volume of precipitation during the snowmelt period 2006. The calculated runoff coefficients, which express the differences between the water storage obtained and the total outflow, can describe the specific characters of the experimental basins. It may be useful for the estimation of the expected inflow into water reservoirs and also for the hydrological forecasting in the foothills of the Jizerské hory Mountains. The measured data of snow cover also serve as a check, and also for the possible adjustment of the snow water equivalent generated by the model SNOW 17 - which is a part of the forecasting modelling system Aqualog. This system is in everyday use for the Elbe river forecasts in the Forecasting Centre of CHMI. The usefulness of this procedure was proved especially during the floods arising from snowmelts in last years. The model SNOW 17 has been calibrated for the catchment of the Černá Desná Stream with the Jezdecká closing profile (one of the experimental basins in the Jizerské hory Mountains). The results obtained demonstrate a very good capability of the model to duplicate the dynamics of the snow cover accumulation and thaw, if quality input data are available.

Spirocerca lupi is accepted in Veterinary Medicine as the cause of true malignancies in dogs. Aortic lesions and esophageal nodular granulomas are pathological lesions of spirocercosis that are considered to be pathognomic for this disease. Post mortem and histopathological studies of 105 stray dogs both male and female of different age groups from various residential areas were performed and their esophagus were examined for any lesions and helminthic parasites. Twenty dogs (19.04%) were infected with S. lupi. The infection rate was significantly higher in dogs greater than one year old (23.5%) and in western areas (36.4%) with similar prevalence rate in males and females. At histopathologic level, two isolate but closely related fibrosarcoma masses were situated at the distal portion of the thoracic esophagus of one dog and in the site of junction of esophagus and stomach of another one. Metastasis were observed in the lung and mediastinal lymph nodes of one of the dogs. Despite presence of large population of stray dogs little information is available about S. lupi in this country, so this study was undertaken to obtain an overall picture of this infection in stray dogs of Shiraz area, southern Iran.

The results of research on the value production of the stands of poplar clones Robusta and I-214 carried out in Slovakia are presented. Models of value yield tables were constructed separately for each clone. The models simulate gross and net financial yield of wood production in dependence on the site index and age of stand. They were constructed on the basis of the models of assortment yield tables, timber prices according to assortments and the models of own costs of timber felling and processing. The clone I-214 produces a faster and higher proportion of thicker assortments of average and below-average quality, and therefore it has the higher value production at a younger age only. Robusta produces smaller diameter but higher quality assortments and has the higher value production only at an older age. The site index of the stand is the most important factor in the value production of poplar clones. Differences in the production between site indexes are much greater than between the clones.

The aim of the study was to assess terrestrial ecosystem development (mainly vegetation and soil characteristics) in the area of a sand mine cast (located in southern Poland) that has been either reclaimed or left for natural succession. A total of 20 sites in a chronosequence of 5, 17, 20 and 25 years were set up in two site categories: reclaimed and non-reclaimed sites. Selected properties of initial soils and features of vegetation were measured and they included carbon accumulation in soil; biomass and diversity of communities were also estimated. Next, based on carbon accumulation, the energy trapped in ecosystem components was estimated. Although the results of plant community investigation did not show the same distinct differences between site categories, the case study suggests that reclamation significantly accelerates ecosystem development. In comparison with spontaneous succession, the complete forest reclamation was found to increase the amount of carbon accumulation, thickness of humus horizon, and energy trapped in soil organic carbon and plant biomass in the developing ecosystem 2-3 times and nitrogen accumulation 5 times.

This paper uses a dynamic, partial equilibrium econometric model to analyze the impact of the 2003 CAP reform and changes of exchange rate on agricultural markets and agricultural incomes in Slovakia. We evaluate three scenarios: (1) baseline scenario with no change in agricultural policies (Single Area Payment Scheme and top-ups are assumed until 2015), (2) CAP reform scenario with full decoupling from 2007 and with modulation from 2013, and (3) exchange rate scenario. In the baseline scenario, production increases. Consumption increases with some exceptions (like pork). Agricultural income rises significantly in the baseline scenario. The full decoupling has a minor impact on agricultural markets relative to the baseline. Weak Euro would lead to higher prices and higher production but lower consumption. Change in the exchange rate causes substitution in consumption of certain commodities due to the relative price changes.

The paper addresses the initiative Tradice Bílých Karpat. It is the example of innovative use of local resources through joining together organic farmers and environmentalists. Content analysis (research technique used in combination with case study) proved to be an efficient tool when evaluating the impacts of this initiative for the public. The results documenting the impacts of this initiative for the public are rather of regional nature. They address only some activities of the Tradice Bílých Karpat, mostly those concentrated around processing of local apples. The paper also outlines the possible reasons for the existing image of this initiative presented in mass media and presenting it for the public.

The purpose of the situation analysis of the external environment is to find what is happening in the company environment now and in the future and how these factors will influence the activities and existence of the company. The paper deals with a situation analysis of the external environment of a specific company. This paper describes the external environment of the United Bakeries company using the STEPE analysis and in addition a situation analysis of the external environment was made. Next the probability estimation of the occurrence and influence of the factors is made for today, and for the near and long-term future.

Fluorescent Maillard compounds measurement provides more specific information on the extent of the Maillard reaction than other unspecific tools to monitor the reaction, and is suitable, as the first approach, to assess the nutritional quality of foods as related to protein damage. This work presents an optimised laboratory procedure for the measurement of total fluorescent intermediate compounds (FIC) associated with Maillard reaction, described and evaluated in a cereal-based product. Total FIC are evaluated using increased pronase E concentrations and different incubation times for the enzymatic hydrolysis, as well as three different sample clean-up steps after the enzymatic digestion. The effects of basic/acid media are considered for the stability of the fluorescent compounds. The standardised procedure is finally applied to breakfast cereals as a model of cereal-based products, analysing the correlation between total FIC production and fibre and protein contents. It is demonstrated that fluorescent compounds are mainly linked to the protein backbone in ready-to-eat breakfast cereals. Fluorescence measurement is presented as an inexpensive, rapid and accurate procedure to study the extent of Maillard reaction in breakfast cereals.

The study compares two methods for modeling the potential distribution of pests when applied to the European corn borer (Ostrinia nubilalisHubner). The development of the European corn borer (ECB) is known to be closely correlated with daily air temperature as well as other climate variables. The climatic parameters are, therefore, used to predict the potential geographical distribution using tested tools such as CLIMEX or ECAMON. These models consider the climatic suitability of a given site/region for the pest's development and, thus, the possible establishment of a population at a given location. In this study, meteorological data from 1961 to 2000 and from 45 meteorological stations were used to characterise the current climate conditions in the Czech Republic. Validation was based on available field data of the occurrence of ECB in the same period. The climate parameters were later modified according to the estimates based on the combination of three SRES emission scenarios and three global circulation models. Under all climate change scenarios, we noted a marked shift of the pest's potential niches to higher altitudes, which might lead to an increase in the infestation pressure during the first half of this century. The present area of the univoltine population will increase due to temperature increases even above 800 m a.s.l. In addition there is a risk of the establishment of a bivoltine population in the main agricultural areas and 38% of arable land in the Czech Republic before 2050.

Sequential extractions, metal uptake by Taraxacum officinale, Ruby's physiologically based extraction test (PBET) and toxicity characteristic leaching procedure (TCLP), were used to assess the risk of Pb and Zn in contaminated soils, and to determine relationships among soil characteristics, heavy metals soil fractionation, bioavailability and leachability. Regression analysis using linear and 2nd order polynomial models indicated relationships between Pb and Zn contamination and soil properties, although of small significance (P < 0.05). Statistically highly significant correlations (P < 0.001) were obtained using multiple regression analysis. A correlation between soil cation exchange capacity (CEC) and soil organic matter and clay content was expected. The proportion of Pb in the PBET intestinal phase correlated with total soil Pb and Pb bound to soil oxides and the organic matter fraction. The leachable Pb, extracted with TCLP, correlated with the Pb bound to carbonates and soil organic matter content (R² = 69%). No highly significant correlations (P < 0.001) for Zn with soil properties or Zn fractionation were obtained using multiple regression.

Producers in highland and semiarid regions have difficulty in increasing diversity in crop rotations due to unfavorable conditions imposed by cool temperatures, inadequate rainfall, and shorter growing periods. In such conditions, safflower appears as a promising alternative because it is cold and drought tolerant. The objective of this study was to determine the responses of the hybrid and open-pollinated safflower genotypes to irrigated and non-irrigated conditions in a highland environment. For this reason, the field research was performed during the years of 2001 and 2002 in eastern Anatolia, Turkey. According to the results of the study, safflower genotypes tested were well adapted to the cool and short-season conditions in this region. The response of seed yield to genotype varied depending on the growing seasons. The non-irrigated plants produced nearly the same seed yield as irrigated ones. Average seed yields of safflower genotypes tested were 914.3 and 928.0 kg/ha in 2001, and 1143.6 and 1139.9 kg/ha in 2002 years for irrigated and non-irrigated experiments, respectively. In general, the genotypes differed in all of the investigated traits. In both irrigated and non-irrigated experiments genotype × year interactions were very significant for all parameters. This research shows that in semiarid and highland environments safflower has a big potential value as an oilseed crop under dryland conditions.

Five grass species (Dactylis glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L.) and the hybrid Felina (Lolium multiflorum L. × Festuca arundinacea L.), commonly used in roughages for ruminants, were harvested at different maturities of primary growth (n = 60) and evaluated for contents of dry matter (DM), crude protein (CP), ash, crude fat, neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL), indigestible neutral detergent fibre (INDF) and digestible neutral detergent fibre (DNDF). INDF and DNDF contents were determined by in sacco rumen degradation of grasses for 12 days in non-lactating cows. ADL content was found to be highly correlated (P < 0.05) with DNDF (r = -0.87) and presented a reliable (R² = 0.78; residual mean square error of 17.65 g/kg DM; P < 0.0001) parameter to predict INDF contents. Over a six-week period of maturation INDF contents increased (P < 0.0001) in all studied grasses. It was confirmed by this study that the INDF contents of grasses, which markedly increased during maturation, could be effectively predicted from ADL contents.

Citrus Greening Disease (CGD) was critically reviewed with respect to its history, origin, symptomatology, host range, pathogenic association, identification and detection, transmission and management. It is evident that the citrus disease has emerged as a potential serious threat to citrus production in all the citrus growing countries of the world including Pakistan. It is has been proved that in Pakistan the greening disease is the major cause of citrus decline; hence it is necessary to formulate definite planning and strategies.

Important parts of the forest sector are forest engineering constructions and capital construction of forest road network which improve the optimal management of forests and forest stands and their reasonable opening by a forest road network. The basic frameworks of forest road network are forest transport roads of various grades and categories. The paper discusses the basic parameters of forest transport roads such as the length of forest transport roads and their density outspread to the area of a particular district above all. The conditions of forest opening in 41 Natural Forest Regions of the Czech Republic and in the Czech Republic as a whole are shown and confronted on the basis of these parameters. A dilemma of the double division of forest transport roads according to the standard ČSN 73 6108 - Lesní dopravní síť (Forest Transportation Network) and according to the methodology used by Forest Management Institute in Brandýs nad Labem is also described in the paper. Although it is not suitable to use two methods of evaluation, there is no tendency to unify it.

The paper evaluates the development of the tree numbers, secondary stand and species composition on eight partial control plots in Klepačov where the conversion of even aged forest managed under the system involving coupes to selection forest has been implemented within the framework of a long-term project. The plots capture various stages of conversion. Plots A, D, and H still possess structures nearing the forest of age classes. The assessment was made of the measurements taken in 1974, 1994, and 2004. Tree numbers on the partial control plots in the diameter degrees 10-70+ decreased in the first inventory period as compared with both the model situation and the initial situation in 1974 due to increased felling volumes in that period. The felling and the subsequent opening of stands resulted in a rapidly developing regeneration, which manifested itself by the increase in the number of trees in diameter degrees 2 and 6 above the values given by the model curve for these diameter degrees. In the second inventory period, tree numbers in these diameter degrees were lower by 11% as compared with the model situation and slightly lower as compared with the initial situation. Moreover, the results of the survey show that the forest stands under the selection system of management are massively invaded by broadleaved species, namely the beech and that danger exists that broadleaves will dominate in the future. This is generally considered undesirable because the quality of broadleaved stems in the stands under the selection system is low.

This report deals with the problems of the status of rural households in the stratification system of the post-socialist Slovak society. The authors take as the basis the concept of associated classification and knowledge about the trends in the development of the social structure of Slovak society in the transformation period. The processing of empirical data from the survey research of rural households in three districts served as an example to compare the classification of households within the economic and socio-cultural lines by the means of the selected indicators. The analysis refers to the inconsistency of the stratification of rural households according to the economic and income statuses as well as education, population and socioeconomic qualities which are significantly conditioned by the regional position and situation. The representative types of rural households for the individual social strata are characterized in the conclusions. They are characterized with regard to the used criteria.

The article deals with communication between a user and an expert system, especially from the viewpoint of psychology aspects of the communication process. Psychological factor of the communication between the user and the expert system seems to be marginal, although it is a necessary part of a final methodology of the expert system development. Domain expert, knowledge engineer as well as IT expert, who takes part in the expert system creation, usually sets up a unified and static communication interface that is identical for all users. The communication process form highly influences user's satisfaction of working with the expert system and his willingness to reuse that system. User's satisfaction expressed by some metrics is one of the key indicators of both efficiency and effectiveness of the expert system. If the system is not used because of the user's discontent, the money spent for its creation cannot be understood as an investment (asset), but as an expense. In the article, there are classified the users from the point of view of their personality type and some recommendations for a communication project development in the frame of the methodology of the expert system creation are suggested.

The objective of this study was to determine the effect of foliar urea applications on quality, growth, mineral content and yield of broccoli under field conditions in 2003, 2004 and 2005. Broccoli cultivars AG 3317 and AG 3324 were treated with foliar urea applications at different concentrations (0.0, 0.4, 0.8 and 1.0%). Foliar applications of urea, especially 0.8 and 1.0% resulted in larger heads, weightier heads and plants as well as higher plants. Conversely, the greatest head and leaf dry matter contents were obtained with no fertilizer-nitrogen application. SPAD chlorophyll readings that were measured in the third year increased with elevated urea concentrations. In regard to the nutrient content, it can be interfered that soil nitrogen fertilization and foliar urea applications increased the content of almost all nutrients in leaves and heads of both broccoli cultivars in three experiment years. Generally, the greatest values were obtained from 1.0% urea application for both cultivars. It results from the study that for optimum yields 0.61 and 0.96% concentrations of urea sprays could be successfully used to obtain better growth and yield in broccoli cultivars AG 3317 and AG 3324, respectively.

The paper deals with the possibilities of arsenic analysis in the soil. The aim is the selection and verification of the methods for analysis of As in the soil, which seem to be suitable for risk evaluation based on the increased As soil load. Economical and analytical availability of the methods is an important criterion. A sample set of 6 heavily contaminated soils was used to compare application potential of prevalent as well as less common procedures for determination of arsenic forms in soils. The results showed that substitution of analytically more demanding As total content analysis and sequential analysis for simple extraction using one-off agents seemed to be promising in many cases. The comparison and evaluation of statistical correlation of used methods of As analysis in the soil was realised. The results suggested that using the combination of simple 1M NH₄NO₃ extraction and determination procedure for amorphous Fe forms in the soil (the Tamm method) was suitable for the risk assessment stemming from the As contamination without necessity of the application of more complicated sequential extraction procedures.

An approximately 7-year-old 1.7kg, female Siamese cat with a history of a malocclusion and an inability to open its mouth was referred the Animal Medical Center, Chonbuk National University. The cat had shown signs since it was adopted four years earlier but the cause was not determined. The mandible was deviated 2 mm to left, the mouth could be opened only 2 mm and attempts to open the jaws caused considerable pain. Radiographs indicated new bone formation and a loss of joint space in the right temporomandibular joint(TMJ). 3-dimensional CT showed bony fusion and bone thickness in the right TMJ. The physical, 3-dimensional CT and radiographic examinations revealed right TMJ ankylosis. Under general anesthesia, surgical treatment was performed to remove the ankylosis block with subsequent interpositional arthroplasty using a temporalis myofascial flap. The patient showed distinct improvement in both the articular functionality and clinical signs.

The population dynamics of wood mouse (Apodemus sylvaticus) was studied in three forest complexes differing in food supply in the intensively managed landscape of southern Moravia. They included an old semi-natural floodplain forest dominated by oak (HL), production broadleaved forest with the predominance of oak and robinia (HA) and a pheasantry with various forest stands consisting of diverse species and age categories of trees with a quantity of additional food for additional feeding of pheasants and roe deer (RB). The population fluctuation within six-year monitoring was affected by seed years (acorn crops in 2003 and 2006), which resulted in an increase in the species population density in the next year. Statistically significant effects of the crop of acorns on the body weight of monitored species were also detected (P < 0.01, F = 1.44). Relative abundance differed significantly between the floodplain forest (HL) and RB and HA (P < 0.01). The two last-mentioned sites did not differ and only a trend of greater preference to the most variable biotope in RB was noted. It evidences the unsuitability of floodplain forest for the species. In spite of the food specialization in small seeds significant effects of the excess crop of acorns can result in a rapid increase in the Apodemus sylvaticus population which can then cause damage to the natural regeneration of oak or artificial regeneration by seeding although to a substantially smaller extent than the more harmful A. flavicollis.

Regional development strategy has to be designed with knowledge of human resources' development trends. Monitoring of this factor is of concern namely in rural areas where disfavourable demographic situation may occur. Leaving this problem unsolved would constitute depopulation of certain endangered regions. The paper is focused on analysis of human resources' condition and development granding groups of settlements by size.
