The position of women in the labour market.
Moskalová, Natalija ; Světlíková, Daniela (advisor) ; Klára, Klára (referee)
The thesis deals with the position of women in the labour market, describes the most obstacles women encounter in the labour market and offers possible solutions. The main objective of the thesis is to analyse the position of the women in the labour market, to define each notion related to discrimination, to recognize the factors that influence it and to find out the differences in remuneration of men and women. Further on, the thesis would like to approach the question if women are still more discriminated on the ground of the sex or whether the society manages to eliminate the discrimination of women thanks to the measures adopted. The thesis is divided into three parts. In the theoretical part of the thesis the legislative adaptation is being introduced, and it presents the effort of the state to eliminate the unequal approach towards women. The thesis analyzes the existing legal regulations of the discrimination law abroad as well as in Czech legislation. Some of the basic concepts linked to the given topic are explained, e.g. equality, positive measures and equal treatment. Another section of the theoretical part deals with discrimination, its forms and variations, discrimination on the reasons of sex and the ways of how to protect oneself from discrimination. In the theoretical part the method of analysis of information sources is used based on research literature. In the practical part of the thesis two ways of questioning are used. The first research method is a structured questionnaire in a form of a standard written questionnaire. A selected group of people is questioned to say their opinion on the given issue. The second investigation is done in a maneuvered interview with the respondents of the first questioning form, based on the prepared set of questions. The last part of the thesis elaborates the results of the research and draws the conclusions from these. Each question has a graph showing the results of the analysis followed by an exact description and explanation. The conclusion of the thesis provides a compact resume of the forms of protection which the discriminated person can use to avoid discrimination or for defense.

Influence of term of winter rapeseed (Brassica napus) desiccation on yield and seed quality
Rajtmajer, Stanislav ; Bečka, David (advisor) ; Petr, Petr (referee)
Rapeseed is the world's third most important oil plant (the second seminal). It is the most cultivation and most important oil plant in Czech Republic. Winter rapeseed reaches about 85% of the harvest area of oilseeds in the country. The desiccation of oilseed crop is sphere of agricultural engineering, which is still worth discussing. The main problems are how to use the product, what dose and which dates to choose to desiccate. The results of this thesis could help to partially clarify this complex issue. The aim of the thesis is to observe the effect of different terms oilseed rape desiccation by glyphosate on yield and seed quality. Small-plot experiments to investigate the influence of the term desiccation of winter rapeseed were established in the years 2013/2014 and 2014/2015 on the lands of the experimental station of the Czech Agricultural University, Faculty of Agronomy Food and Natural Resources at the Červený Újezd. In the first experimental year 2013/2014 was founded five variants in three replications (including undesiccated control). In the year 2014/2015 was founded seven variants in four replicates (including undesiccated controls). In the first experimental year was the first term desiccation 16. 6. 2014, the second year 8. 6. 2015. Subsequent periods of desiccation were a week apart. The variety of winter rapeseed used for the experiments was a hybrid variety Rohan. The desiccating agent was used Dominator active substance glyphosate. The dose of 4 l / ha + 200 l H2O. For all samples, both experimental, years yield was determined, the weight of a thousand seeds and oiliness. For desiccated variants were carried out pre-harvest analysis for the determination of solids in pods. Further, all harvested samples taken for laboratory germination test (Determination of germination) ISTA according to the methodology. The results of the experiment sprouting were statistically analyzed using ANOVA analysis of variance. Differences between mean values were evaluated by Tukey test, the computer program SAS at a significance level of p = 0.05. Effect of desiccation term influences of winter oilseed rape seed quality in terms of weight and thousands of seeds in terms of oil content. Too early desiccation (46 to 39 days before harvest) HTS reduced by 7-17% and the oil content of 2-4% of the overall average. Oiliness of the observed characters minimum interference term desiccation. Desiccation in the optimum date (17 days before harvest) increased oiliness of 1-6%. Influence term desiccation oilseed rape also greatly influences seed yield. Too early desiccation (46 to 39 days before harvest) reduced the yield by 11-14%. Undesiccated control in both years achieved the highest yields, increase yield by 5-12%. Desiccation in the optimum date (17 days before harvest) increased the yield of attempts by 5-6%. The term desiccation of winter rapeseed, also significantly affects the vitality of seeds, where very reduces energy germinating seedlings in the first days. The term desiccation, however, does not affect overall seed germination. Too early desiccation (46 to 39 days before harvest) EK2 decreased by 12-40%, EK3 decreased by 4-24%, 3-4% EK4 and extended MGT of 7-15%. In the first experimental year was the most vital option undesiccated control (EK2 = 50.4% = 91.3% EK3, EK4 = 97.9%). In the second experimental year was the most vital seeds of the optimal term desiccation, (Sixth term, 17 days before harvest) = 68.9% EK2, EK3 = 98.2%, EK4 = 100%. Seed samples of 2014/15 had a higher overall vitality of seeds, than samples from 2013/14, the overall vitality is probably worse given year old and transsilaged seed. The results of the two-year experiment that term desiccation affects the quality of seeds, the yield of seeds and vitality of seeds. Pre-analysis was determined optimum solids content in siliques desiccated samples to values of 40-50%. Like most technology seems to desiccation in the optimum date (17 days before harvest) and agro technology without desiccated vegetation. As the least appropriate technology seems very early desiccation (46 to 30 days before harvest). The first scientific hypothesis: Premature desiccation reduces seed yield, oil content and HTS. Yes, the hypothesis was confirmed. The second scientific hypothesis: Desiccation made in the correct term do not affect the quality of the seeds (oiliness and HTS). Yes, the hypothesis was confirmed.

This thesis analyzes the process of integration of Thai migrants into Czech society. The main aim is to explore the issue of Thai integration in Czech Republic by a quantitative research which haven`t been done fully in Czech Republic yet. Then on the basis of gained data to compare the state with another countries and to set the strategy of Thai integration in Czech Republic among the classic patterns of migrant behaviour or to identify the differences which could be specific only for Czech Republic. The thesis consists three main parts: theoretical, descriptive and practical. The introduction outlines the background of Thai migration. The theoretical framework, that follows, sets the gained information into theoretical concept of migration theories and defines important terms that accompany this thesis. Those analyzed information then help to evaluate the data gained by the practical part. The integral component of the thesis is descriptive part which outlines the development and reality of the investigated topic. The results of the questionnaire survey and interviews among Thai migrants in Czech Republic are presented in the practical part of this work. The conclusion establishes discourse between the theory and observed findings. There is also an assessment of the achieved results within the frame of...

The Effect of Oregano Essential Oil on Microbial Load, Drying Kinetics and Sensory Atributes of Dried Meat
Hernandez Hernandez, Helga Johana ; Banout, Jan (advisor) ; František, František (referee)
Microbial load can be controlled using either synthetic or natural preservatives. Particular interest has been focused on the potential application of plant essential oils as safer additives for meat. However, there is no published research on the use of essential oils during the meat drying process. This study was focused on enhancing the meat drying process. At first a value-added dried meat product by using oregano essential oil (OEO) to inhibit the growth of bacteria, and the sensorial response from assessors is presented. It was found that the application of the OEO in meat is effective in inhibiting Salmonella enteritidis and Escherichia coli. After 6 hours of drying at 55°C, 2 ml (0.038 ml l-1 air) and 1.5 ml (0.028 ml l-1 air) of OEO were considered the minimal inhibitory concentrations (MICs) against S. enteritidis and E. coli, respectively. Samples treated with 0.75 ml of OEO were more attractive for consumption compared with the control; at a higher concentration of OEO, the sensory quality of the food was affected. Next, the effect of modified blanching treatments on the drying behaviour of beef meat was evaluated by determining moisture ratio versus time curves and the influence on sensory quality of the resulted product. The 3 treatments under investigation were (1) oil treatment (2) steam blanching and (3) hot air blanching with 3 doses of oregano essential oil (1) 1.5 ml (2) 3 ml and (3) 6 ml. Each treatment had an effect on the drying time of the beef samples, however, the dose of oregano essential oil applied did not affect the drying process. The results showed that steam blanching was very effective reducing the drying time. Meanwhile, 1.5 ml and 3 ml hot air blanching samples and 1.5 ml oil treatment samples were judged as better from sensory point of view and the respondents considered that adding oregano essential oil enriched the pleasantness of the smell. In conclusion, a value-added dried meat product obtained by using oregano essential oil to enhance food safety received an acceptable sensorial response from consumers. Additionally, each modified blanching treatment tested influences the drying kinetics process, but the dose of oregano applied did not affect the drying process. In this sense, hot air blanching and oil treatment with the lowest dose had an acceptable sensorial response from consumers.

Biotransfer of selected risk metals into plants and their accumulation and distribution in plant organs
Le Minh, Phuong ; Lachman, Jaromír (advisor)
Contamination of soils with heavy metals is one of the serious environmental problems threatening human being. Heavy metals are considered as the special hazard of soil pollutants because of the adverse effects on the plant growth, the amount, activity of useful microorganisms in soils and the quality of food. Regard to the persistent and toxicity, the heavy metals are toxic when we consider different kinds of pollutants in soils. In the soil, zinc (Zn), cadmium (Cd), lead (Pb) and mercury (Hg) toxicities frequently occur than the other metals because of their precipitation and sorption by the soil. It is a very dangerous situation because when these metals are taken up by plants, they can be transported to the food web and food chains. In the present study, the accumulation of four heavy metals (mercury, zinc, lead and cadmium) in the whole grain of spring accessions of emmer, einkorn and common spring wheat cultivars and potato (Solanum tuberosum) is reported. Heavy and essential elements were monitored in potato cultivars in the exact field experiments and in hydroponically grown plants. The elements were determined by methods FAAS, ET AAS, and AMA (Advance Mercury Analysis). Statistical analyses were performed using SPSS 9.0 with the Tukey HSD (Honestly Significant Difference) test (alpha equal to 0.05). In our study, the concentration of heavy metals decreased in the order zinc (Zn) > lead (Pb) > cadmium (Cd) > mercury (Hg) in the wheat grain. The comparison between three varieties of investigated wheat revealed that the emmer wheat was rich in zinc content (62.12 mg kg-1 dry matter), while the spring wheat had the lowest average concentration of zinc in the grain (40.99 mg kg-1 dry matter). Generally, the values of lead concentration in grain wheat varieties were low (ranging from 0.1268 mg kg-1 dry matter to 0.2950 mg kg-1 dry matter). The concentrations of mercury in four typical growth stages of wheat (boot stage 10, heading stage 10.2 1/4 of head emerged, leaf-stage 10.2 and stage ripening 11 according to Feekes) were also determined. It has been shown that the concentrations of mercury in different wheat varieties were absorbed differently at different growth stages of plant. Stage 10.2 and leaf stage 10.2 showed the high mercury content (0.0152 mg kg-1 dry matter and 0.0214 mg kg-1 dry matter, respectively). Among individual varieties significant differences were determined. Amounts of toxic and potentially toxic elements detected in investigated potato tubers are characterized by a large variability within investigated groups. Performing statistical analysis (one way ANOVA) showed that there were no significant differences between two investigated groups of samples (samples from Uhříněves and Valečov in the year 2013 and 2014) considering either one of investigated metals. Measurable levels of mercury were found in smallest amounts in all investigated potato samples comparing to other metals (Cd, Pb). Plant cells compared to animal cells are characterized by the formation of cell walls. Plasma membrane or cell membrane is a biological active membrane separating the interior of cell from the outside environment. An adjusted method for isolation of protoplasts was developed and adapted for isolation of protoplasts from plant material (potatoes). In our experiment, the plants were grown hydroponically in the Research Institute of Plant Crops Prague-Ruzyně. If we examine the plant membrane, one option is to remove the cell wall by means of special mixture enzymes. Protoplasts were released in the dark at 25 degrees of Celsius for 18 hours. The 70 and 90 microns sieve was used to filter and then centrifugation for 5 minutes at 100 x g. All the steps were carefully carried out to prevent the damage or breakage of protoplasts.

Effect of Drying Pretreatments on Air and Solar Drying of Jerky Prepared from Eland (Taurotragus oryx) Meat
Kučerová, Iva ; Banout, Jan (advisor) ; Oliver, Oliver (referee)
Mathematical modeling of thin-layer solar drying and organoleptic properties of eland jerky was investigated in this study. Eland jerky was compared to the traditional beef jerky, inasmuch as both were treated with traditional jerky marinade (TM), TM with fresh pine apple juice (TMP), TM with honey (TMH), TM with Coca Cola (TMCCL) and compared to an untreated control (C). The influence of the marinades on the drying process was statistically significant. Based on the coefficient of determination, the root mean square errors and the chi-squares, the Two-term model was found to be the most suitable model for describing the solar drying kinetics of eland jerky. The mean effective moisture diffusivities of solar dried eland meat for the C and selected pre-treatments TM and TMH samples were 2.07 x 10-10, 1.45 x 10-10 and 1.43 x 10-10 m2.s-1, respectively. The activation energy values for solar dried eland jerky were 23.75, 26.22 and 26.97 kJ.mol-1 for C, TM and TMH, respectively. Organoleptic properties of dried eland meat was assessed by the 22 member degustation panel. The best scored pre-treatment was TMP, which has significant effect on texture, color and taste. Effect of the different pre-treatments on the overall combined color was calculated. Generally for both meat dried in both driers TMH marinade was evaluated as the one with the highest total difference contrariwise meat dipped in TMP pre-treatment has the lowest total difference.
