The diploma thesis deals with the protection of competition in the Czech Republic with a focus on telecommunications. The literature research describes in imperfectly competitive markets, competition, telecommunications sector and forms of his regulation and legislation in the Czech Republic and the European Union. The own part of the thesis deals with the analysis of the competitive environment of the telecommunications market and regulator measures in the Czech Republic.

The diploma thesis was focused to forest management of alder stands on the groups of forest habitat types 3L and 1L aiming to enhancement of quality production. The stands are located in the forest ranges Býchory,Ledce and Nymburk. On those localities alder is only marginal tree species even though according to the rule No. 84/96 Sb. about forest management planning alder belongs to the important soil improving and reinforcing tree species in several management sets of stands. While the stocking on the forest habita types 3L is insufficient in many cases the stocking on the forest habitat types 1L is optimal. . The stand 204 which is 41 years old, has stock volume 182,65 m3/ha, the stand 308 at the age of 39 years has stock volume 129,28 m3/ha. The stand 616 at the age of 72 years has stock volume 220,67 m3/ha and the stand 617 at the age of 72 years has stock volume 212,12 m3/ha. The tending proposal presents the alder silviculture as the integral part of forest ecosystems in the given landscape for the future management. 511E7 vegetation at the age of 76 years old has a of 167,13 m3/ha. Vegetation 511J8 at age 90 has a vocabulary of 203,33 m3/ha. Vegetation 512D5 at the age of 58 years old has a vocabulary of 166,75 m3/ha. The tending proposal is aimed to improvement of the quality status of stands and to maintenance the alder in forest ranges as an integral part of the landscape.

The aim of the dissertation work was to determine meat colour in cattle, sheep, pigs, poultry and pheasants. The aim was also to evaluate the effect of breed, age at slaughter, weight at slaughter, sex, content of intramuscular fat and feed on changes in meat colour. Lightness (L*), redness (a*), yellowness (b*), chroma (C*) and hue (h) of CIELab system were measured by spectrophotometer Konica Minolta CM 2600d in all analyzed samples. In selected samples both remission and content of colour pigments were measured using photocolorimeter Spekol 11 and by modified method according to Hornsey. According to the results pork meat was affected by selected biological factors in the smallest range. Sex of the fattening pigs (hogs and gilts) had not significant effect on meat colour, on none of the monitored parameters. Neither sire lines did affect colour meat parameters. Significantly the lightest (p < 0.05) meat L* (62.53) was found in group with the highest content of intramuscular fat (5.04 -- 9.50 %). The colour of beef was affected by chosen factors in the widest range. In bulls, heifers and steers the highest lightness L* was found in crossbreed with Charolais (L* 36.22; 37.23; 37.19). The type of cattle had a significant effect (p < 0.01) on meat colour in cows. There were observed significant differences (p < 0.01) between crossbreed of beef breed (L* 36.89) and dairy breed (L* 31.94), respectively dual purpose breed (L* 33.57). Czech Fleickvieh breed (C) had significant effect on pigments content in meat (p < 0.01) when crossing with dairy breed. There was found significant difference (p < 0.01) between crossbreed with C 50 -- 74 % (3.94 mg.g-1) and purebreed C 100 % (3.57 mg.g-1). The breed of lambs had not significant effect on meat colour (p > 0.05). The level of DDGS in broiler diets had a significant effect on meat colour (p < 0.05). The highest (p < 0.05) L* (55.58) of breast muscles was determined in broilers fed 10% DDGS in the diet. Colour of broilers meat was affected not only by the level of DDGS but also by extruded soybeans (EPS). Breast muscle was darker (p < 0.01) in EPS (L* 52.58) in comparison with breast muscle of broilers fed DDGS (L* 55.74). In pheasants there were not significant differences (p > 0.05) between sexes in breast meat colour. Sex of pheasants had significant effect (p < 0.01) on lightness (L*), redness (a*) and hue (h) in thigh muscles. Values a*, b*, C* and h of breast meat were significantly (p < 0.01) different between pheasants reared in aviary in comparison with pheasant from the wild. Thigh muscle was significantly darker (p < 0.01) in pheasants from wild than in pheasants from aviary.
