The Wine Market in the Czech Republic and the Politics of Wine
Vlašicová, Eliška ; Tomšík, Karel (advisor) ; Malý, Michal (referee)
The dissertation thesis is focusing on the wine market in the Czech Republic. The aim is to identify weaknesses in the wine sector in order to formulate recommendations for improving a current situation in the sector. The Common Agricultural Policy of the European Union and the Common Market Organisation for Wine was presented in the theoretical part of the thesis, where also theoretical aspects of a market including supply and demand were described, as well as an agri-food market and its specifics, wine commodity chain, determinants of demand, supply and prices of wine. In the following chapters an analysis of the wine market, especially with emphasis on the production potential of vineyards in the Czech Republic was created, and demand, supply and price of wine including a price transmission in the commodity chain of wine were modelled based on a regression analysis. The significant influence on demand of wine have had previous values of wine consumption and wine prices, substitutes consumptions (prices of substitutes were not a significant factors), household income and salary, a quality of the wine and awards in international competitions. Significant factors of the side of supply including the price of wine grapes, the price of wine, vineyard area, production of wine grapes, some aspects of weather and certain subsidies. A climate change, which is in progress, may result to the expansion of viticulture and winemaking in the Czech Republic and also to a change of varieties in vineyards. Demand has in the commodity chain of wine greater impact than the supply. It can have a negative effect on growers or winemakers. Planting of vines is not sufficient to maintain current levels of a production potential of vineyards in the Czech Republic. The ideal amount of annual planting vines should be about 655 ha. A related issue is financing a vineyards renewal, which is costly. Based on a financial analysis of small and medium-sized wine companies, it was found that these businesses cannot afford the renewal of vineyards from its own resources and will require grant assistance of the state, eventually EU.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell. During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation. The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL. In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found. To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Felix Mendelssohn Bartholdy and his Compositions for the Cello and the Piano
Šístek, Eduard ; ERICSSON, Mikael (advisor) ; KAŇKA, Michal (referee)
This thesis offers a brief overview of the life and the work of Felix Mendelssohn Bartholdy. It was no coincidence that Robert Schumann called him the Mozart of the 19th century: Being a prodigy from a very early age, he composed with such an unbelievable lightness. Many of his compositions have become an essential part of the world of music nowadays. Equally, his pieces for the cello and the piano, which are dealt with in the second part of the thesis, have their remarkable qualities and they are worth playing.

A pair of phase-synchronized semiconductor lasers for length metrology
Hucl, Václav ; Holá, Miroslava ; Čížek, Martin ; Řeřucha, Šimon ; Pham, Minh Tuan ; Pravdová, Lenka ; Lazar, Josef ; Číp, Ondřej
Semiconductor lasers are increasingly widespread in areas that have been so far dominated by He-Ne lasers. One of such areas is the length metrology, where He-Ne laser operating at 633nm wavelength is still a traditional source of coherent light for laser interferometers distance measuring. The advantages of semiconductor lasers compared with He-Ne laser are greater optical power and a significantly wider range of wavelength tuning without mode jumps. Another advantage is the possibility of frequency modulation of wavelength of the laser diode by directly changing the injection current. The benefits predetermine these laser diodes for the realization of dual-frequency laser sources for heterodyne interferometry. In this case, using a phase-locked loop technique the optical frequency of a laser diode is locked to the optical frequency of another laser diode with a certain frequency offset in the MHz order. In our contribution we present utilization of DBR laser diodes in implementing a dual-frequency laser source for laser interferometry with heterodyne detection.\n

Rules, bans, restrictions in healthcare facilities
KODETOVÁ, Věra
Rules, bans, restrictions in healthcare facilities Improving the quality of care for patients is the main goal of every healthcare facility. Satisfaction of patients with medical and nursing care is one of the indicators of quality. Patients have not only rights but also duties. Among other things, patients{\crq} duties include compliance with rules, bans and restrictions during a visit to healthcare facilities. This particularly concerns compliance with therapeutic rules, instructions given by a physician and other limitations associated with the operation of a healthcare facility. The main objective of this diploma thesis was to identify the patients{\crq} attitude and perception of rules, bans, and restrictions, find out how patients observe them and compare the number of rules, bans and restrictions in both outpatient and inpatient healthcare facilities. The data was collected in a survey undertaken in Nemocnice s poliklinikou Praha Italská (Hospital with Outpatient Clinic Prague Italska). This healthcare facility has 2 hospital wards and 31 specialist outpatient departments. A total of 188 respondents took part in the survey (102 outpatients and 86 inpatients). Five hypotheses were proposed. The first hypothesis, which predicted that most patients would perceive rules, bans and restrictions as burden, was not confirmed. The second hypothesis, which predicted that rules, bans and restrictions that were personal would create more stress in female patients than in male patients, was confirmed. The third hypothesis was also confirmed since female patients from outpatient departments of the healthcare facility were shown to be more compliant with rules, bans and restrictions than male patients. Female inpatients from hospital wards of the healthcare facility were not more compliant with rules, bans and restrictions than male inpatients. The fourth hypothesis was not therefore confirmed. Our assumption that inpatients from hospital wards of the healthcare facility are facing more rules, bans and restrictions than outpatients was disproved. The fifth hypothesis was not therefore confirmed. The author has chosen this topic for her diploma thesis because as a nurse she meets different kinds of patients on a daily basis who react differently to rules, bans and restrictions in this healthcare facility. The results of the survey led us to design training classes for nurses and information brochures for patients who visit healthcare facilities. A sufficient amount of information is a basic prerequisite for understanding and complying with rules, bans and restrictions.

Location-aware data transfers scheduling for distributed virtual walkthrough applications.
Přibyl, Jaroslav ; Sochor, Jiří (referee) ; Sojka, Eduard (referee) ; Zemčík, Pavel (advisor)
Důležitou součástí aplikací procházení distribuovanou virtuální scénou je proces plánování přenosu dat. Jeho hlavním úkolem je zajištění efektivního přenosu dat a maximální kvality renderovaného obrazu. Největší vliv na kvalitu renderované scény mají omezení síťového připojení. Tyto omezení lze redukovat pomocí multi-resolution reprezentace dat scény, určováním priorit stahování jednotlivých částí scény, a přednačítáním dat. Pokročilé metody pro určování priorit a přednačítání částí scény jsou založeny na predikci pohybu uživatele vycházející z matematického popisu jeho pohybu. Tyto metody jsou schopny predikovat následující pozici uživatele jen v krátké vzdálenosti od jeho aktuální polohy. V případě náhlých, ale pravidelných změn směru pohybu uživatele jsou tyto metody nedostatečné co do přesnosti i délky predikce. V této práci je navrhnut komplexní přístup k řešení plánování přenosu dat splňující i tyto požadavky. Navrhované řešení využívá predikci pohybu uživatele založenou na znalostech k určení priority stahování dat i předstahování částí scény. Provedené experimenty nad testovacími daty ukazují, že navržené schéma plánování přenosu dat umožňuje dosažení vyšší efektivity přenosu dat a vyšší kvality renderovaného obrazu během průchodu testovací scénou.

Cultural Centres
Adolfová, Barbora ; PROKOP, Petr (advisor) ; KAŠPAR, David (referee)
This thesis is concentrated on cultural centres built between years 1960 and 1990 in the former socialist Czechoslovakia. Six cultural centres have been chosen and analyzed to conclude the purposes they serve as well as the programs they offer. These chosen cultural centres are run as municipal organisations financed from the town budgets. The six towns where they are located are similar to each other in terms of their history, size and the time when their cultural centres were built. All of these centres share difficulties with the lack of cultural interest of local citizens, bad technical shape of the buildings in question and low budget. The aim of this thesis is to compare the functioning of these six cultural centres and conclude whether being directly funded and influenced by the municipal councils has a positive impact and should serve as a model for cultural centres or should be replaced by a different one. It also focuses on cooperation between the management of cultural centres and municipal officials, cooperation with other local cultural institutions and cultural centres from different towns.

Characteristics of the working behavior of Czechs and Ukrainians
BYKOVA, Sofia
The aim of this work is to create a transparent and comparable characteristics of the work behavior phenomenon within the cultures of those states - what is common and what is different between them, or maybe incompatible .It is supposed to have some analysis of possible conflicts and their connection with the mentality. The primary reason of this aim choosing is the specialty I study. My work contains information that could be interesting and useful not only for me and my future job, but also for managers and other employees. Overview of examined issues contains specific points, such as the fundamentals of economic psychology and behavioral economics (symbiosis of psychological and economic opinion on motivation and rationality of individuals), theories of motivation and reaction to different occurrence, characteristic of the term "mentality", general points about the human impact of the world economy. For realizing the goals of my work the following hypotheses have been proposed - Czech and Ukrainian mentality have significant differences, though these cultures are close. - Ukrainian and Czech employees are able to work effectively in a team and find a "common language" in the workplace. The difference in mentality does not obstruct on it. - Employers could be interested in the Ukrainian employees taking into account their high concernment and motivation. All three of the hypotheses were confirmed by observed data and comparison of mentality characteristics. Czechs are often tolerant to other cultures, moreover Ukrainian culture is not much different and does not create difficulties in the working relationship. Based on the fact that the chosen company has no conflicts associated with work behavior and differences in mentality, it's hard to define my contribution to this organization work.
