: In the Czech Republic, there is still a predominance of obsolete apple orchards that were established more than 15 years ago and that are not profitable under contemporary conditions. Typical features of these orchards are low or medium tree densities, freely growing semi-standard trees or hedgerows on semi-dwarf, or sometimes also on vigorous, rootstocks. The farmers are not always in a position to completely renovate them, and therefore they are interested in their topworking. The present paper studied the effectiveness of this measure under the current economic and market conditions of this country, using 3 types of orchards with different spacings and rootstocks and 5 groups of tree densities. Four cultivars were chosen as examples of different starting statuses for the modelling of subsequent development in three time horizons and for the prediction of profitability of this treatment. The profitability is based on an increase in farmer prices for cultivars that are presently recommended for replacement of the older ones according to the recent development of these prices on the fresh market. In the case of topworking for Spartan cv., an economic return of the measure can be expected at the earliest after 8 years of running the treated orchard. The greatest increase in profit can be achieved in orchards on the rootstock M 9. Nevertheless, with the decline of tree numbers in the orchard, or with the increase in tree losses, the general economic effectiveness of topworking notably falls. In the case of trees on the rootstock MM 106, this measure can have an economic effect only if at least 80% of the trees is in a good health state and it is presumed that the orchard will be used for another 10 years at least. A list of recommended cultivars to be used for replacement of the old ones is given.

The important part of the increase of regional potential is the farming of the land fund. The economic conditions for its utilisation have been already prepared. They are based especially on the drawing of funds of the European Union, namely for the period after the accession of the Czech Republic to the European Union and for the years 2007–2013. The measures concerning the land are included in the prepared programme documentation, especially in the Horizontal Rural Development Plan (HRDP) and in the Operational Programme “Agriculture”. The farmers will obtain the direct payment per area (SAPS) in addition to supports on foregoing measures. The requirements for environment-friendly farming of land will be increased in the future. The economic conditions for next period will concentrate on these priorities. It will concern the securing of public benefit contributing to the sustainable development of rural areas. The project assurance of these trends and their regional monitoring and evaluation will be important.

The levels are reported of the free 3-chloropropane-1,2-diol (3-MCPD), its bound forms, the recognised precursors of 3-MCPD, and the factors influencing its formation in 5 selected coffee surrogates and 18 malts in the Czech Republic. The coffee surrogates had the free 3-MCPD level in the range of < 9.0 to 32 &micro;g/kg while the highest amount was found in roasted barley. In malts, the free 3-MCPD levels were similarly low (< 9.0 to 45 &micro;g/kg) being the highest in roasted malts (16-45 &micro;g/kg). Nevertheless, the values found in either surrogates or malts, calculated after normalisation to 40% dry matter content, did not exceed the European Union limit of 20 &micro;g/kg adopted for soy sauces and acid-HVP. The risk for consumers could arise from the bound 3-MCPD, its elevated levels having been found in both coffee surrogates and malts. In coffee surrogates, the bound 3-MCPD levels varied between 145&minus;1184 &micro;g/kg product; the highest level was found in roasted barley. The bound 3-MCPD levels exceeded the free 3-MCPD levels 32 to 81 times. In malts, the bound 3-MCPD levels ranged from 4.0&minus;650 &micro;g/kg, the highest amount having been found in roasted malts (463&minus;650 &micro;g/kg). The bound 3-MCPD levels exceeded the free 3-MCPD levels 0.4 to 36 times.

Forest management in the Czech Republic (CR) was not shaped in the environment of natural forests but in the territory that was influenced by unregulated felling and animal grazing for a long time. Hence the fear for sustainable and balanced benefits from forests endangered by long-term uncontrolled exploitation was legitimate. Almost after three centuries of application of the sustainability principle, forests are considered not only as a source of renewable wood raw material but also as a tool of the environment formation. Mountain forests are an important landscape component of this country. They are an object of specific importance from the aspect of natural environment conservation, stabilization of natural processes and general landscape homeostasis. In addition, they fulfil a number of production and non-production functions. Cardinal elements of sustainable forest management in the CR conditions are as follows: management of the forest as an ecosystem, i.e. transition from exclusive care of forest tree species and their stands to care of the whole forest ecosystems; restructuring (conversion, reconstruction) of damaged and declining forests; optimum (species, genetic, spatial, age) structure of forest ecosystems differentiated according to site conditions and management targets; differentiated transition from general management to group or individual methods; utilization and support of spontaneous processes such as natural regeneration, competition and other principles of self-regulation. The above cardinal elements of sustainable forest management are applicable to forests of the CR in general, but their importance considerably increases in mountain forests where many species survive on the margin of subsistence. Moreover, mountain forests of CR have been heavily destroyed by anthropogenic factors, especially air-pollution ecological stresses, during the last three or four decades.

Tick-borne encephalitis virus (TBEV) is the most important arboviral agent causing disease of the central nervous system in central Europe. In this study, 61 TBEV E gene sequences derived from 48 isolates from the Czech Republic, and four isolates and nine TBEV strains detected in ticks from Germany, covering more than half a century from 1954 to 2009, were sequenced and subjected to phylogenetic and Bayesian phylodynamic analysis to determine the phylogeography of TBEV in central Europe. The general Eurasian continental east-to-west pattern of the spread of TBEV was confirmed at the regional level but is interlaced with spreading that arises because of local geography and anthropogenic influence. This spread is reflected by the disease pattern in the Czech Republic that has been observed since 1991. The overall evolutionary rate was estimated to be approximately 8×10−4 substitutions per nucleotide per year. The analysis of the TBEV E genes of 11 strains isolated at one natural focus in Žďár Kaplice proved for the first time that TBEV is indeed subject to local evolution.

The paper focuses on the current problem of factors influencing the reading of non-artistic texts and the development of reading strategies of pupils of secondary technical schools in the Moravian-Silesian Region of the Czech Republic. The paper aims to reflect, describe, analyse and evaluate which types of non-artistic texts, images, and depictions develop pupils' reading strategies. The text presents selected results of the quantitatively oriented questionnaire survey focusing on the identification of the relationship between the pupil's notion of a non-artistic text and course of work with the image as factors influencing their reading strategies. The partial goal of the pilot research is to point out the factors influencing student teachers at the Faculty of Education of the University of Ostrava in working with non-artistic text, an image in the text and their understanding.
