On existing conditions on global market (almost identical quality, almost identical purchasing values) companies have to definite the total rating of importance of evaluative criteria. In post-crisis period the problem of suppliers' evaluation is one of the biggest, because companies had to use all resources and all possibilities to develop their own business. Many authors wrote about collaborative planning and warehousing as one of possibilities to optimization work inside supply chain. For this paper define small and medium-sized enterprises (SME) as enterprises with the size of maximum 250 employers.
In literature was read we couldn't find information about own system of suppliers evaluation for small and medium-sized enterprises.
SME can have some different types of business and in this case need the universal system of evaluation. The research of this paper is oriented on small and medium-sized enterprises with different types of business. The new theoretical universal method of calculation for evaluation existing suppliers for small and medium-sized enterprises will present in this paper. This theoretical method is based on average values. This method includes traditional evaluative criteria (quality, delivery time) and other (mobility of supplier, possibilities of new level of partnership). This method of evaluation can not be used for continual manufacture. New method can improve the total evaluation of supplier in small and medium-sized enterprises.

Research of the reproduction activities of Dendrobates auratus Girard, 1855 is part of a broader analysis of the problems encountered when keeping frogs from the family Dendrobatidae in captivity. The aim is to achieve an optimization of measures for successful breeding of these amphibians, for both the amateur hobbyist and conservationist alike. Due to the wide area they have colonized, many colour variations exist; the reproduction parameters of six differently coloured examples of the species were tracked. The collection of data happened in standardized conditions over two consecutive years (2007, 2008) and was aimed at measuring five indicators concerning reproduction, understanding of egg-laying dynamics during a year, measuring the risk of stock loss during different stages of development and determining if any differences existed between the different colour variations in these parameters. A noticable alternating cycle of rest and reproduction activities has been observed between equinoxes. In the harvest there were usually 5-10 eggs with an average incubation period of 10 days (8-18) at a temperature of 22 °C. The total duration of development was on average 74 days (64-103). The number of eggs in a harvest and the duration of incubation were statistically different with the blue form between different observed periods. Total mortality rate during ontogenesis reached 10-53%, the highest losses were in the period when the tadpole left its egg and began developing its hind legs, 5-60%. The optimisation of breeding conditions has been reccommended. Secondary benefits of this study research was the collection of new knowledge about ethology of this species in captivity.

In the world the interconnection of national economies and internationalization of economic processes occur. In turbulent changing business environment only those companies that understand the current trends in global economy may survive, develop and prosper. Therefore, the issue of internationalization for most companies becomes to be more important and the process of internationalization is the way how to stand this increasingly competitive environment. In presented contribution, the attention is paid to issues of internationalization of Slovak food industry enterprises such as their way of business internationalization, percentage share of foreign - trading activities on overall business activity, company evaluation of business internationalization or barriers of foreign markets penetration that researched companies have to deal with. Small and medium-sized enterprises (SMEs) are the engine of the Slovak economy, generator of development, innovation, growth and they employ more than 60% of employees. Almost all businesses operating in agri-food complex have character of small and medium enterprises. The results of carried research have shown that small and medium-sized companies are considered to be successful in operation on foreign markets in surrounding European countries.

The study is aimed at analysing the role of location as a factor affecting development of rural communities. Research findings presented in the paper are based on the findings from survey conducted by the Department of Social and Regional Policy of IAFE-NRI in 2006. Study showed that location of villages close to urban areas (especially where local self-government is located) affects their economic development. In opinion of almost every fifth of surveyed villages' representatives, location close to the town influenced development of entrepreneurship.

Studies on the effect of ashes on maize were conducted as a pot experiment on mineral soil, to which between 13.33 and 800.0 g ash∙pot^-1 was added, corresponding to the doses of between 10 and 600 t∙ha^-1. The research aimed to learn the effect of diversified ash doses on the content, uptake and proportions between Fe, Co, Mn, Al and Si in maize. It was found that with increasing ash dose in soil were significantly increasing the concentration of Fe and Si in plants (Fe: 110.15-209.96 mg.kg^-1 d.m.; Si: 40.60-76.10 mg.kg^-1), whereas concentrations of Co, Mn and Al in maize were decreasing (Co: 0.30-0.11 mg.kg^-1 d.m.; Mn: 207.83-44.65 mg.kg^-1; Al: 300.09-179.80 mg.kg^-1 d.m). Higher contents of the studied elements were detected in maize roots than in its aboveground parts. Obtained yield of maize aboveground parts from the objects where solely ash was used as the substratum was characterized by the optimal content of Fe (104.61 mg.kg^-1 d.m.), but deficient concentration of Mn (29.69 mg.kg^-1 d.m.) and Co (0.01 mg.kg^-1 d.m.). In effect of growing ash doses in soil Fe:Co, Fe:Mn, Fe:Al and Mn:Co ratios were widening, whereas Fe:Si, Mn:Al, Mn:Si and Al:Si ratios were narrowing. Growing ash doses in soil influenced a decreased uptake of Co, Mn and Al and increased Si absorption by maize.

The paper evaluates seven years (1993-1999) of Soil organic matter supply monitoring in multifactor field trials conducted by the Agricultural Research Institute in Kroměříž, Czech Republic, (mean annual temperature 8.9 °C, total annual precipitation 599 mm, medium Luvi-Haplic Chernozem). The studied plots were a part of nine-crop rotation: alfalfa the 1^st and 2^nd year, winter wheat, spring barley, sugar beet, spring barley, winter wheat, silage maize and spring barley. The Soil organic matter supply was measured on four plots: winter wheat after spring barley (var. 1), winter wheat after alfalfa (var. 2), spring barley after winter wheat (var. 3) and spring barley after sugar beet (var. 4). Soil samples were taken from April to July (14-day period) from topsoil (0-30 cm) and subsoil (30-60 cm). The content of Soil organic matter was determined by wet oxidation. Using bulk density, the C content (%) was converted to C supply (t.ha^-1). Average yield (t.ha^-1) reached 6.54 t/ha (var. 1), 7.47 t/ha (var. 2), 6.52 t/ha (var. 3) and 7.20 t/ha (var. 4). Evaluation of the results was carried out by the analysis of variance and time changes by the second-degree regression analysis. Results demonstrated that Soil organic matter supplies were significantly changed in topsoil. The highest supplies were found in barley after sugar beet (118 t.ha^-1), the lowest ones in wheat after alfalfa (111 t.ha^-1). As for the cereal species generally, it was documented that in topsoils under barley the supplies were higher than under winter wheat. In subsoil, there were significant differences between wheat after alfalfa (111 t.ha^-1) and barley after wheat (104 t.ha^-1). As for a difference in the Soil organic matter supply in subsoil according to the cereal species the situation was contrary than in topsoil. Higher supplies were under wheat. Generally (topsoil and subsoil), the highest supply of Soil organic matter was in barley after sugar beet (224 t.ha^-1) and similarly in wheat after alfalfa (222 t.ha^-1). The smallest supply was in the variant of wheat after barley (217 t.ha^-1). In topsoil, the average supply of humus was 114 t.ha^-1 and that in subsoil was 107 t.ha^-1 the difference being statistically significant.

The study presents the results of research on the use of barley caryopses hardness for prediction of the malting quality. Grain hardness was determined by three methods: Particle size index (PSI), hardness according to Brabender (BRA) and grain milling energy (GME). The correlations among methods for determining the kernel hardness were estimated as well among selected technological traits of barley and malt and kernel hardness. Significant correlations were found among PSI values and Final attenuation of laboratory wort from malt (0.73*) a Glycidic extract (0.70*). Values of kernel hardness measured by BRA significantly correlated with Final attenuation of laboratory wort from malt (-0.80*) and Soluble nitrogen of malt (0.64*). Grain milling energy values were statistically significant correlated with Nitrogen content in malt (0.64*). The preliminary results confirmed the possibility to use kernel hardness for prediction of some malting quality traits. Further studies will be done on larger number of samples.

The most business entities in Europe are small or medium-sized enterprises (SME), which have a legal obligation to prepare financial statements in accordance with a set of accounting principles accepted in their country. Those statements are available to creditors, suppliers, and national governments but they could be badly understandable to creditors, suppliers and subjects in other countries. This is a great obstacle of their activities in the EU internal market. The existence of 27 different national accounting systems in the EU can be held for the most important obstacle.
There are many ways how to develop compatible accounting standards for SMEs but the most significant activity in this field is the research project of IASB (International Accounting Standards Board). IASB has developed IFRS (International Financial Reporting Standards). Even though IFRS are suitable for all enterprises, their application in case of SMEs would be very expensive and could significantly increase compliance costs of taxation. This development has not been finished yet and there are still some problems which need to be solved before the introduction of accounting standards to the public.
The research has shown that IFRS for SMEs should be used mainly by the entities which do not have public accountability - i.e. that its equities are not publicly traded and do not hold assets in a fiduciary capacity for a broad group of outsiders. This paper discusses those IFRS modifications, which should be done in case of SMEs.

The subject of the Rájec project (the Drahanská vysočina Upland) consists in the analysis of ecological impacts of intensive management in spruce monocultures growing on original sites of beech. Long-term studies were aimed at particular stand and environment stages after clear-felling regeneration and at the origin of a spruce monoculture of the 2^nd generation. The establishment of the spruce monoculture can be considered to be most important. The highest attention was paid to the monoculture both from the aspect of carbon and nitrogen in particular components of the forest stand and their transport processes as well as from the aspect of water regime and biodiversity. The study was also aimed at the first stage of the clear-felled area development after felling a mature stand and also at functions of the herb vegetation, which reached its maximum production 4 to 7 years after felling. The paper objective was to assess spruce monocultures even outside their natural range from the aspect of changes in the forest environment as well as from the aspect of possible global changes of climate.

Due to the expansion of phylloxera into European vineyards rootstocks became an integral part of successful modern growing of grapevine. Breeding of rootstocks and their selection for resistance against both biotic and abiotic factors can be classified as a biotechnology. In this respect, the capability of grapevine plants to adapt themselves to pedological conditions, especially to drought and a high content of lime (or factors inducing their chlorosis) represents a very important breeding goal. In this survey possible causes of lime-induced chlorosis and drought damage and their consequences are analysed. Some important drought-and-lime induced chlorosis-related properties of some selected rootstocks are mentioned as well.

The paper deals with the results of a pilot study themed "Czech students and EU", which adumbrated a prepared extensive research in graduation years of secondary schools of the region Vysočina on the occasion of the Czech chairmanship in the European Union in the first half-year of 2009. The pilot study included 362 students of the Polytechnic College in Jihlava. Its objective consisted particularly in the rectification of a questionnaire and exploratory research into relationships between the knowledge and opinion parts of questionnaires even within the both mentioned parts by means of factor analysis and methods of structural modelling. With respect to the considerable number of respondents and standard conditions, which were ensured at completing the questionnaires it is not possible to ignore even results concerning the knowledge and views of the group of respondents as a whole as well as particular specific segments. Our research was inspired by a "Eurobarometer", but with respect to a fact that (unlike the Standard Eurobarometer) it refers to a specific target group, ie studying young people, it concerns only partly and only in some questions comparable examination. Therefore, the questionnaire (in contrast to Eurobarometer) involves also the knowledge part. This part includes eight fields. With respect to the study orientation of the respondents surprisingly worse results occur particularly in fields Institution, politics and law of EU (30% successfulness) and Economy and finance of EU (37% successfulness). On the contrary, the highest successfulness (of course, only relatively) was noted in fields Culture, education and sport in EU (63%). Generally, knowledge of students can be unambiguously evaluated as poor. The opinion part includes in total 20 items, which are divided into five fields. In particular respondents, sex, the size of the place of residence, political profile, social group of a household, ideas of a future carrier, knowledge of languages and interest in problems of EU were determined by means of identification questions. As for the opinion part, it is possible to state that opinions of students are not too marked (answers in the central part of an evaluation scale predominate but, at the same time, all values of the scale were used in all questions) and differences between segments of respondents are generally insignificant. The subject of the paper is particularly aimed at the analysis of results of the opinion part, in the concrete eight items from two fields (Social dimension of EU and Me and EU). For the first area, segments were compared according to sex and political orientation and for the second area, according to sex, language knowledge and interest in EU problems.

As a consequence of a rapidly changing environment, the success of organizations is dependent upon the ongoing and immediate adjustments of their information systems as reactions to these changes. Therefore, flexibility becomes one of the most crucial features in information systems. This paper specifies a data model oriented framework for the development of flexible information systems. The result of such process is a system that is sufficiently general and flexible in relation to solving problems related to changing environment. From general requirements related to data layer of information systems the paper discusses the definition of major elements of logical data model (entities and their hierarchical arrangement, attributes of the entities and their important characteristics, relationships among entities and their characteristics) as well as possibilities of implementation and definition of application logic and data presentation. Proposed framework enables the organization to specify its own database structure, which best matches the situation of the organization and its environment. Because an approach similar to meta-data approaches is applied, methods for information sharing and interchange can be easily specified as well as program logic for manipulation with the data base on the application layer and data presentation.

Rheological properties of Brie cheese with different time of ripening (1, 3, 4, 5, 6, 7 and 8 weeks) were evaluated. This evaluation has been performed using the indentation test at the constant speed of the indentor penetration (20 mm/min). Two types of the indentors (bar and ball) have been used. The hardness of the cheese increased during the first three weeks of the ripening and than it decreased. The properties evaluated from the indentation test approved the isotropic behaviour of the tested cheese. The viscoelastic properties of the tested cheese have been obtained. The se properties were achieved using a methodology enabling to convert the indentation force-displacement response into the stress-strain relations. The obtained viscoelastic properties are independent on the used type of the indentor.

The paper is focused on appreciation of differentiation of demographic development in CR regions. There are defined key factors of essential influence in a demographic situation on the basis of principal component analysis. With use cluster analysis there were created groups of regions with similar development. Analysis of basic regional differences follows.
Pieces of knowledge introduced in this paper resulted from solution of an institutional research intention MSM 6046070906 "Economics of resources of Czech agriculture and their efficient use in frame of multifunctional agri-food systems".

Objective of the paper is to point out selected patterns of Slovak consumers based on analysis of buying behaviour. Results of presented survey of consumer buying patterns and preferences have pointed out key characteristics of buying behaviour of Slovak consumers. We're able to confirm that new business companies as hypermarket and supermarket became main place for food shopping. Totally 72% of respondents indicated them as the type of store where they spend largest share of food expenses. The self-service shop, traditional business units, is still the shopping place for 14% of respondents. The most important factors influencing selection of the type of store are closeness and location of the store, assortment and product quality, store personnel and price level. More than half of the respondents consider opening times the key service for choosing the place for shopping. 49.6% of respondents is using car to do shopping, 35.5% of respondents walk. 32.5% of respondents is using advertising leaflets to plan what to buy. 14.6% of respondents answered that even though receiving leaflets, they don't read them. 31.3% of respondents are holders of loyalty cards. Most visited retail chain is Tesco.
Currently building of large-scale business formats slowed down and retail chains try to get closer towards customer not only by reducing floor space but above all by locating the stores in the centre of cities with lower population.

Lilac sage (Whorled sage), as one of the medicinal plants chosen as perspective for the recultivation of flowering meadows in the Czech Republic, was studied for the variability of its morphological characters, seed quality and content of essential oil. Seven particular populations of this genus were studied in the Czech Republic and there were found statistically significant differences in morphological characters (height and width of plants, length and width of leaves and length of inflorescences) but not in the content of the essential oil. Studied populations reached only between 0.028 and 0.072% of essential oil in dry mass and also the quality of seeds was found very low (germination between 0-52%) in the seeds from natural localities but this fact could be influenced by testing method.

The aim of this study was to determine the effect of a yeast culture (Saccharomyces cerevisiae CNCM I - 1077) addition in the diet of dairy cows on their rumen fermentation. Animals received a diet consisting of good maize silage with a higher dry matter content (18 kg), 6 kg of lucerne haylage, 5 kg of pea - silage, 3 kg of ensiled high moisture crimped corn, 1 kg of meadow hay, rape-cake 1 kg, brewer's grain silage 4 kg, and 8.0 kg feed mixture. The yeast culture was added to the mixture in the dose 2.8*10¹⁰ cfu/day and cow. The supplement of yeast culture showed a positive effect on ruminal VFA production by experimental group cows in comparison with control, higher production (P < 0.01) of acetic acid (58.50 ± 1.2583^b vs. 51.833 ± 2.409^a %), and lower production of propionic and butyric acid (24.667 ± 1.3744^a vs. 28.833 ± 1.863^b %). The average utilisation of ammonia was higher by cows in treated group (12.267 ± 0.754 mmol/L), but difference was not significant. The difference in number of protozoa of cows in the control and experimental groups was significant (P < 0.05) different (308.333 ± 24.390^a vs. 342.333 ± 10.9341^b ths /1 ml of rumen fluid).

The decision support systems commonly used in industry and economy managerial practice for optimizing the processes are based on algoritmization of the typical decision problems. In Czech forestry business, there is a lack of developed decision support systems, which could be easily used in daily practice. This stems from the fact, that the application of optimization methods is less successful in forestry decision making than in industry or economy due to inherent complexity of the forestry decision problems. There is worldwide ongoing research on optimization models applicable in forestry decision making, but the results are not globally applicable and moreover the cost of possibly arising software tools are indispensable. Especially small and medium forestry companies in Czech Republic can not afford such additional costs, although the results of optimization could positively influence not only the business itself but also the impact of forestry business on the environment. Hence there is a need for user friendly optimization models for forestry decision making in the area of Czech Republic, which could be easily solved in commonly available software, and whose results would be both, realistic and easily applicable in the daily decision making.
The aim of this paper is to develop the optimization model for the machinery use planning in Czech logging firm in such a way, that the results can be obtained using MS EXCEL. The goal is to identify the integer number of particular machines which should be outsourced for the next period, when the total cost minimization is required. The linear programming model is designed covering the typical restrictions on available machinery and total volume of trees to be cut and transported. The model offers additional result in the form of optimal employment of particular machines. The solution procedure is described in detail and the results obtained are discussed with respect to its applicability in practical forestry decision making. The possibility of extension of suggested model by including additional requirements is mentioned and the example for the wood manipulation requirement is shown.

The paper includes results of research work dealing with the study of the effect of mixing the traditional urea-formaldehyde adhesive Kronores CB 1100 D and the urea-formaldehyde adhesive Kronores CB 1200 D characterised by increased reactivity for selected physical and mechanical properties of particleboards, the content of free formaldehyde and productivity of the production line of particleboards. Within the research, other potential factors affecting properties of particleboards were also studied. Present adhesive prescriptions (1) and five experimental prescriptions were evaluated. In conclusion, optimum prescriptions were determined fulfilling the CSN EN 312 standard requirements for physical and mechanical properties of particleboards of P 2 class and a pressing factor was defined substantially affecting the rate of a production line or production productivity.

The paper presents the software procedure (using MAPLE 11) intended for considerable reduction of digital image data set to more easily treatable extent. The example with image of peach stone is presented. Peach stone, displayed on the digital photo, was represented as a polygon described by the coordinates of the pixels creating its perimeter. The photos taken in high resolution (and corresponding data sets) contain coordinates of thousands of pixels - polygon's vertexes. Presented approach substitutes this polygon by the new one, where smaller number of vertexes is used. The task is solved by use of adapted least squares method. The presented algorithm enables reduction of number of vertexes to 10 % of its original extent with acceptable accuracy +/- one pixel (distance between initial and final polygon). The procedure can be used for processing of similar types of 2D images and acceleration of following computations.

Series of the indentation of the ball (10 mm in diameter) by the constant speed into blocks of Edam cheese has been conducted. The indentation tests were performed at different speeds (1, 5, 10, 20 and 100 mm/min), and the corresponding force-displacement responses were fitted with an analytical solution to obtain the time-dependent constants and the instantaneous force-displacement response. The measurement has been performed for the cheeses of different stages of their maturity. The dependence of the indentation force on the penetration depth has been evaluated. This dependence can be fitted by a polynom. The indentation force decreases with cheese fat content. It increases with the loading rate. Its value also decreases with the time of the cheese ripening. The recently proposed method for the indenation of the ball into viscoelastic solids has been used for our data analysis. This procedure, which needs the use of the numeric methods, enables to obtain stress relaxation moduli, which describe the viscoelasticity of the tested materials. The obtained moduli describe the stage of the cheese maturity.

Besides agricultural primary production, the food industry and all other branches of the economy /services/ it is the information and communication technology used in retail that is one of the factors that markedly influence food retail. Therefore it is necessary to analyse the effect of electronic transactions that are used by food retail to attract and acquire other target groups of the consumers purchasing food. Though globally the retail companies (for ex. in Great Britain) invest in this technology heavily in order to increase their competitiveness on the market the food e-business in the Czech Republic has been more or less stagnating, though the recent years have been showing slight increase of interest in this form of shopping. This article identifies both the positive and the negative reasons of this situation. The technological level of computer network and its high accessibility proven by the fact that the vast majority of consumers can use internet for purchasing any kind of goods incl. food can be considered the positive reason. On the other hand the poor offer of food presented on the internet by retailers who - for fear of low demand for other kinds of food - focus mainly on beverages and dry food can be considered one of the negatives. The weakest point here is the timely delivery of goods in unchanged quality. Despite these facts the purchasing of food via internet can still serve well for busy or handicapped customers with limited mobility.

Risk management should ensure a company to be able to react to possible future situations in a good advance and through variant solutions. This should minimize both, a risk and possible negative risk consequences especially on trade and on a single existence of a company. Solution of negative consequences of risks is the one of important goals and of investigation of companies' management as well as of companies' owners. Submitted article presents the procedure of entities' risks selection for the purpose of their negative consequences covering by the means of insurance. This procedure has been elaborated by the author based on secondary research as well as on primary research. Author's primary research has been focused especially on observation and analysis of several tens of entities. The procedure presented in this article has been also fruitfully implemented in observed entities. The content of this article would become an asset of risk management as of the branch of science; it would be a benefit for insurance as for connected branch, and also for the sphere of management economics.

The paper is aimed at the evaluation of a relationship between the rate of investments and the rate of savings in selected Central European countries. A reference period for the analysis is 1995-2009. In all analysed Central European countries, the rate of investments permanently exceeded (but exceptions) the rate of savings in the period under investigation. Through fitting the development series of a calculated indicator as a difference of the rate of investments and the rate of savings in monitored countries by a polynomial of the second degree it was possible to compare developmental trends of this indicator in particular countries involved in this analysis. Polynomial trends of the difference indicator of the rate of investments and the rate of savings in Central European countries in the monitored period indicate similar developmental tendencies characterized (at the beginning of the reference period) by increasing the imbalance of the rate of investments and the rate of savings (on average until about 2003) and then by follow-up tendencies towards the gradual return to the balance. For the purpose of comparison, a difference was also monitored between the rate of investments and the rate of savings in EU15 countries as a whole, which permanently fluctuated around zero. The mean value of this indicator amounted to 0.11% for the period 1995-2009. Thus, in EU15 countries, the rate of investments roughly corresponded to the rate of savings (on a long-term basis). Based on this analysis, it follows that there is a correlation between the rate of investments and the rate of savings. Calculated parameters of particular regression functions are presented as Results in this paper. Indices of correlation and types of a regression function were calculated for particular countries. For the Czech Republic, these results are statistically highly significant using all three types of regression functions. In Poland, they can be indicated as statistically significant using the polynomial of the second and third degrees similarly as in Slovakia. In Hungary, already the use of a polynomial of the first degree results in statistically significant results. Using a polynomial of the third degree gives statistically highly significant results. The intertemporal analysis of investments and savings presented in this paper can be also used and developed as part of the problem of an intertemporal approach to the balance of payments.
