LINEÁRNÍ MODELY PŘÍJMOVÝCH VZTAHŮ VE SPOTŘEBITELSKÉ POPTÁVCE PO POTRAVINÁCH A ANALÝZA PRUŽNOSTI TĚCHTO VZTAHŮPavel Syrovátka, Miroslav NavrátilActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(6), 173-188|DOI:10.11118/actaun200553060173 The paper is focused on the use of the linear constructions for developing of Engel's demand models in the field of the food-consumer demand. In the theoretical part of the paper, the linear approximations of this demand models are analysed on the bases of the linear interpolation. In the same part of this text, the hyperbolic elasticity function was defined for the linear Engel model. The behaviour of the hyperbolic elasticity function and its properties were consequently investigated too. The behaviour of the determined elasticity function was investigated according to the values of the intercept point and the direction parameter in the original linear Engel model. The obtained theoretical findings were tested using the real data of Czech Statistical Office. The developed linear Engel model was explicitly dynamised, because the achieved database was formed into the time series. With respect to the two variables definitions of the hyperbolic function in the theoretical part of the text, the determined dynamic model of the Engel demand for food was transformed into the form with parametric intercept point: |

Teoretické vymezení podnikových akcií a dluhopisů soudobého světového kapitálového trhuOldřich RejnušActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(3), 171-184|DOI:10.11118/actaun200553030171 The article deals with the theoretical classification of "classic" capital market securities, i.e. corporate stocks and bonds. Its aim was to make a detailed analysis of the individual types of these securities from the viewpoint of their main characteristic features, and to look for possible ways of systemizing them and distinguishing them as unambiguously as possible. As the aim of this analysis was to identify the most important and typical properties of not only corporate stocks and long-term bonds that are commonplace in investing but also of those that are rare on financial markets, the analysis was made from a global viewpoint, i.e. without regard to the individual countries' legislative conditions. |
O vybraných reologických vlastnostech komerčně distribuovaných kečupůLibor Severa, Jana Simeonovová, Ivo Křivánek, Jaroslav BucharActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(2), 7-18|DOI:10.11118/actaun200553020007 The rheological properties of four different ketchups were determined. The viscosity, shear rate and shear stress were measured by use of Anton Paar DV-3 P Digital Viscometer and received data can be successfully characterized by several models, primarily by Hershel - Bulkley model. The ketchup was found to be a typical time-dependent thixotropic fluid. Shear stress and viscosity decrease with time of shear. Decrease during first 300 s is more significant than later decrease. The influence of spindle speed, shear rate potentially, on a sample viscosity was observed. The viscosity was rapidly changing during low speeds. The data were compared with Carreau model. Many other dependeces (low and high shear rates, difference between mixed and rested material etc.) were observed and modelled with satisfying results. Dependence of shear stress on shear rate under two temperatures was also examined. The tendency of increasing shear stress with increasing shear rate is evident. The samples were examined under temperature 22 °C and temperature 7 °C. |

Vliv rozdílné technologie zpracování půdy na druhové spektrum plevelů v ozimé řepceJan Winkler, Věra ZelenáActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(5), 187-194|DOI:10.11118/actaun200553050187 A community of weeds and crops is affected by a number of factors, including, among other things, also tillage. In the years 2000-2002, the composition of weed species in rape stands was evaluated on the fields with the total area of 551 hectares (1 hectar equals to some 2.47 acres). The evaluation was carried out with the application of methodology developed by Kühn (1982). On the fields located in the cadastral area of Olomouc - Holice, which had been cultivated in a traditional manner, 115 relevés were recorded. On the fields in the cadastral area of Bohuňovice, which had been cultivated with the application of reduced tillage, 97 relevés were recorded and evaluated. All of the above fields were subjected to the application of chemical agents reducing the occurrence of weeds. The data thus received were processed by means of multidimensional analysis of ecological data with the application of a RDA method (Redundancy Analysis). In the course of three years, 75 weed species were found on the fields under conventional tillage, on the average, 8.2 species per a relevé, while 66 weed species were found during the same period of time on the fields cultivated by means of reduced tillage, on the average, 8.6 species per a relevé. The application of RDA analysis enabled us to sort out the selected species of weeds (i.e. those the frequency of occurrence of which exceeded 15 %) into three groups. The conditions provided by the conventional tillage appeared to be more satisfactory for the weed species included in the first group (Arctium tomentosum, Elytrigia repens, Helianthus tuberosus, Chenopodium album, Lolium perenne and Papaver rhoeas). The species included in the second group, i.e. Alsinula media, Apera spica-venti, Atriplex patula, Bromus sterilis, Capsella bursa-pastoris, Equisetum arvense, Fallopia convolvulus, Myosotis arvensis and Thlaspi arvense., responded to reduced tillage by the increase in cover or by increased frequency of occurrence. The third group consists of species such as: Cirsium arvense, Chamomilla recutita, Galium aparine, Lactuca serriola, Matricaria maritima, Triticum aestivum and Viola arvensis. Their cover and frequency of occurrence were in a more degree influenced by factors different from the type of tillage. The manner of tillage appears to be only one of a number of factors that affect the occurrence of weed species. It influences them together with other factors and it is a factor of polyfunctional nature. |
Vybrané aspekty modelování devizového kurzu pomocí neuronových sítíVáclav MastnýActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(3), 109-116|DOI:10.11118/actaun200553030109 This paper deals with forecasting of the high-frequency foreign exchange market with neural networks. The objective is to investigate some aspects of modelling with neural networks (impact of topology, size of training set and time horizon of the forecast on the performance of the network). The data used for the purpose of this paper contain 15-minute time series of US dollar against other major currencies, Japanese Yen, British Pound and Euro. The results show, that performance of the network in terms of correct directorial change is negatively influenced by increasing number of hidden neurons and decreasing size of training set. The performance of the network is influenced by sampling frequency. |

Mendelianae Brun. 2005, 53(5), 143-150|DOI:10.11118/actaun200553050143 Fennel (Foeniculum vulgare var. vulgare Mill.) is an perennial herb, it is cultivated for the essential oil in the fruits. The quality criteria are essential oil content, microbiological contamination and residua of pesticides. The important part of the cultivation technology is ununiform maturity of the fruits. The aim of this work was to find out the influence of the desiccants on quality and yield characteristics of fennel fruits produced in field conditions in the first years of growing. Three preparations were applied: glufosinate-NH4, 150 g.l-1 (2 l.ha-1), diquat dibromide, 200 g.l-1 (3 l.ha-1) and glyphosate-IPA, 480 g.l-1 (3 l.ha-1) in three repetitions. The non treated control variant was also repetited three times. The samples were analysed for quantitative and qualitative parameters: the fruit yield (t.ha-1), the essential oil content (%, V/m), the essential oil yield (kg.ha-1), the essential oil composition and the residua content. |

ANALÝZA EKONOMICKÉ AKTIVITY A NEZAMĚSTNANOSTI OBYVATELSTVA JIhom*oRAVSKÉHO KRAJEJaroslava HudečkováActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(3), 49-58|DOI:10.11118/actaun200553030049 This article deals with analysis of the South Moravian region population economic activity and unemployment state and development. The analysis of the population economic activity and unemployment is a part of the demographic, social and economic population analysis. The unemployment is considered to be an unfavourable effect, but its low rate is a natural part of the market economy. The unemployment was from the general and registered unemployment rate in years 1995-2003 point of view evaluated. Some indicators of the South Moravian region were with the whole Czech Republic compared. The unemployment in the South Moravian region marked a negative development in mentioned period and in the year 2003 achieved value of 11.45%. The trend of the unemployment development was defined and also the seasonal character with the seasonal indexes was analysed. The highest unemployment was proved in winter months (January-March) and least in May and June. There was proved the high dependency rate among the number of vacancies, the number of applicants for one vacancy and unemployment rate. |
Statististická analýza agregátů souhrnného zemědělského účtu české republiky v období let 1998-2003Božena Bodečková, Erich MacaActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(6), 19-32|DOI:10.11118/actaun200553060019 Results of the statistical analysis of the of the total economic aggregate account for the Czech Republic enabled, in addition to the quantification of its performance, also to asses the developmental tendencies of economic phenomena under study. From this point of view, the most important were the data obtained within the framework of studies on the total output of Czech agricultural industry. Among the major indicators of the production intensity, the level of intermediate consumption was explored as well. This analysis involved also an exact estimation of both gross and net added value because such an analysis enables to express the the final economic effect of agriculture within the framework of the national economy as a whole. A complex approach to the solution of these problems is presented on the base of studies on the structure of both plant and animal production and of the total intermediate consumption |

Výzkum využití indikátorů ukládání biologicky rozložitelných odpadů (BRO) na skládkuJana KotovicováActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(5), 91-98|DOI:10.11118/actaun200553050091 The orientation of the research work for the exploitation of the preventive tools for the decrease of biodegradable waste comes out from the requirements, which are reposed on Czech Republic as a valid member of European Union. The Czech Republic have to follow the legislative requirements, which are defined for the waste treatment, in this case it deals with the EC Landfill Directive (1999/31/ES). The directive undertakes for the EU members to limit the volume of the biodegradable waste on the landfills. The main sense of this restriction is to reduce the volume of the emitted gas, mainly methane, into atmosphere. Therefore, it was assigned the Waste Management Plan of the Czech republic, which states in the interest of the strategic goals (the decrease of the specific waste production independently on the level of the economic growth, the maximal waste exploitation as a reserve of the primary natural resources and the minimalization of negative impacts on human health and environment by the waste treatment) the goal achievement in its binding part, what's the decrease of maximal volume of the biodegradable municipal waste deposited in landfills, thus the rate of this element will be the most 75% weighted in 2010, the most 50 % weighted in 2013 and the most 35 % weighted from the total volume rised in 1995. One of the ways, how to achieve the required reduction of the waste volume deposited in the landfills, is consistent exercitation of the preventive methods and the sound agricultural and sound operating practice methods. The main goal of the work consists in creation of methodics for the make prognosis of the region development charging by the biodegradable waste in the preventive tool exploitation. I identified the typical sources of biodegradable waste and the key areas of their uprise after the evaluation of environmental gains of the selected preventive projects by the creation of methodics. After this manner of data acquirement, I proposed and defined the indicators, which serve for the creation of model database of environmental gains in the regional measure, especially collection area of landfill. |

Mendelianae Brun. 2005, 53(4), 43-50|DOI:10.11118/actaun200553040043 In the years 1999 to 2001 in conditions of small-plot field experiments was carried out on loamy degraded chernozems at the Plant Breeding Station of Sládkovičovo-Nový Dvor to solve the problems of topdressing winter wheat (Triticum aestivum, L.), variety Astella, with different forms of nitrogenous fertilizers. Nitrogenous fertilizers were applied at the growth phase of the 6th leaf (Zadoks = 29). Four various forms of fertilizers were exemined: urea solution, DAM-390, DAM-390 + Dumag, DASA. Different weather conditions statistically highly significantly influenced grain yield in respective experimental years. Topdressing with nitrogen (30 kg N.ha-1) caused statistically highly significant increase of grain yield in all fertilized variants ranging from +0.29 t.ha-1 (applied of DAM-390) to +0.69 t.ha-1 (applied of DASA) according to respective treatments. Average grain yield in unfertilized control variant represented 7.23 t.ha-1. Nitrogen nutrition showed positive effect on the main macroelements offtake (N, P, K, Ca, Mg, S) by winter wheat grain in all fertilized variants. Nitrogen fertilizing positively influenced formation of wet gluten and crude protein with highest increment in variant with DASA and variant with DAM-390 + Dumag. |

Frekvence genotypů a alel PvuII polymorfismu genu estrogenového receptoru (ESR) u plemene bílé ušlechtilé a landraseEliška Goliášová, Josef DvořákActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(2), 33-38|DOI:10.11118/actaun200553020033 Genotype and allele frequencies of the oestrogen receptor gene (ESR) PvuII restriction site were investigated in populations of the main Czech maternal breeds. 1253 sows and gilts and 396 boars in Large White and 334 sows and gilts and 318 boars in Landrace were genotyped from blood samples by the modified PCR-RFLP procedure as described in Short et al. (1997). In Large White, the frequency of allele B was about 0.51. In Landrace, the frequency of allele B reached from 0.02 for boars to 0.03 for sows. No significant deviations of the observed genotype frequencies from the frequencies expected according to Hardy-Weinberg equilibrium were found in both breed. Opposite trends in allele frequencies development could be assumed for analysed sows and boars of both breeds. In Large White sows the frequency of allele B raised probably due prefering sows with BB genotype, whereas in Landrace population the frequency of allele B decreased from yet unknown reasons. |

Mendelianae Brun. 2005, 53(4), 145-150|DOI:10.11118/actaun200553040145 Measurements of 7 body measures and 6 indices of body conformation on 34 breeding individuals of Moravian warm-blooded horse and 19 of Sarvar horse (Leutstettener) were used to analyse the effect of country of origin (Czech Republik, Germany), sire lines or breed (Furioso, Przedswit, English thoroughbred, Sarvar, Others) and age (4 classes). All horses were measured by one person. Measures and indexes were analysed by GLM procedure. Significant differences were found between both Czech and German population only in index of body frame. Sarvar horses are longer to their height than Moravian warm-blooded horses. The shorter body frame have the horses by English thoroughbred, the longer by Furioso. The younger horses are higher than the older. According to results of Linear Description of Body Conformation we found out, that population of Sarvar horse is more balanced than population of Moravian warm-blooded horse. |
Konzistence podnikových procesů vyjádřenÁ formálním aparátem transakcíMilan Mišovič, Ivana RábováActa Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(3), 117-126|DOI:10.11118/actaun200553030117 Using a progressive Information Technology for development of Software Modules for Enterprise Information Systems brings a lot of practical and theoretical problems. One of them is a verification of results achieved in Life Cycle Stages. Object Oriented Analysis has the main position in the Object Life Cycle of Information Systems. It gives fundamental diagrams that will be processed in the Design and Implementation phases. We mention diagrams for enterprise processes and their refining to enterprise transaction diagrams. The Unified Modeling Language (UML) has been very often used to enterprise processes and transactions modeling. There is one of very practical and theoretical problems concerning enterprise processes - their internal consistency that can be observed on the level of object transactions. We have in mind such problem as transaction feasibility and object cooperation feasibility in transactions that are strongly bound with states of objects. Therefore, a testing of object complex transactions before their programming appears to be very useful activity. |
Daňová optimalizace při prodeji nehmotného majetkuEva FábkováActa Univ. Agric. Silvic. Mendelianae Brun. 2004, 52(6), 225-230|DOI:10.11118/actaun200452060225 During the implementation of their activities on the market, a lot of companies deal with the issues of increasing their market shares, the know-how improvement, gaining competitive advantage over their competitors, etc. One of the possibilities how to solve out the said problems is for instance the acquisition of know-how, databases, software, and patents which will provide the company with the competitive advantage from another company. At the acquisition of the assets, there is a great space for the tax optimisation, i.e. how to purchase (sell) the assets with the minimum tax burden. |
