Do women with children have lower wage rate than childless women?
Lukášová, Nikola ; Brožová, Dagmar (advisor) ; Čermáková, Klára (referee)
The aim of the thesis is to demonstrate if women with children in the Czech Republic have a lower wage rate than childless women. The data from WageIndicator Foundation was processed by using the the least squares method. The conclusion is that motherhood has a negative impact on salaries. I also found that the depreciation of human capital influences only women with two or more children. It can be caused by the lenght of maternity leave. The main finding is that the wage penalty for motherhood actually exists. And the society and politicians should give the motherhood penalty more attention in the future.

The Issue of Contraception and Reproductive Health Care among Young People
BŘEZKOVÁ, Markéta
The dissertation is focused on the issue of contraception and reproductive health of young people. I therefore chose this topic of my dissertation because it interests me and it is also very current topic. I have specified the research in various types of secondary schools in Cesky Krumlov. The main aim of my dissertation was to map the knowledge of hormonal contraception and proven possible differences in sexual self behaviour in adolescent girls attending different high schools in Cesky Krumlov. The research was conducted using anonymous questionnaires that were distributed to girls aged 17 to 19 years. For my dissertation, I set four hypotheses that have been statistically confirmed. The results were interesting and there had been statistically significant differences in the level of knowledge about the risks of hormonal contraception among female students of Secondary Schools and other female students of Health Secondary Schools. In addition, the Vocational School students begin sexual life before other students of Secondary schools. Also the most common method of protection at first sexual intercourse is condom, but the most preferred contraceptives in adolescent girls, regardless of the type school studied, is hormonal contraception. According to the responses of girls we can see the differences in their own sexual behaviour, which is, in most cases conscientiously. Girls, however, are not sufficiently informed about hormonal contraception they use. I would advise to bring more lectures into schools about the positives and risks of hormonal contraception in general and also about all contraceptive options.

Awareness of women about nutrition problems such as breast cancer prevention
STAŇKOVÁ, Denisa
This thesis focuses on the awareness of women of the nutrition issue as the prevention of breast cancer. The aim of this thesis is to find out whether the women have enough information about nutrition and life style as the prevention of breast carcinoma, where they look for information, if they are interested in this issue and whether they consume food that could work as the prevention. Another goal is to detect possible differences in the attitude to the prevention between women without the potential risk and women with the increased risk, i.e. women over 45. Research questions were determined as follows: "What is the knowledge of women about the issues of nutrition as the prevention of breast cancer?", "What is the proportion of the food that has preventive effect on the rise of breast carcinoma and, on the contrary, the food that supports the tumour growth in the eating habits of women?", "Where do women get information on this issue?", "What is the difference in awareness and consumption of food between women without the potential risk and women with the increased risk, i.e. over 45. The thesis is divided into two parts, a theoretical and a practical one. In the theoretical part I focus on the breast anatomy, basic information on breast cancer and risk factors that are divided into influenceble ones and non-influenceble ones. In the most extensive part of my thesis focuses on the influenceble factors, that is nutrition and life style. I focus especially on nutriments, food and other life style factors that are most connected with breast cancer and have antitumour effects or, conversely, support the tumour growth. The practical part was made by means of a questionnaire which I placed on the Internet and handed out in the waiting room at the general practitioner. The questionnaire was anonymous with 34 questions of a closed and semi-enclosed type. Questions concerned nutrition and life style in relation to the risk of breast cancer and were devised to answer previously defined research questions. The questionnaire survey took place in January and February 2013. I acquired 105 filled in questionnaires from which I randomly chose 86 to obtain two numerously equal groups of women without the potential risk and with the increased risk, i.e. over 45. The result of the research part is that women do not have much information on the life style in connection with the breast cancer. Some respondents, while selecting food with preventive effect, were only guessing and often also marked food which was not related to the breast carcinoma at all. About one third of the respondents even believe that nutrition and other factors are not related to this disease at all. One third of the respondents also stated that they had no interest in learning more information on this issue. Women that have some information usually get it from the magazines and from the Internet. In terms of eating habits, the food of most respondents does not reach the needed quantity to have preventive effects. On the other hand, the food and drinks that support tumour growth do not occur on the menu of the respondents very often. While comparing answers of the women younger 45 and the older group of respondents, it was found out that the younger respondents showed greater unawareness of this issue. No significant differences were recorded in other questions. The results of the survey are graphically processed and evaluated in the final part of this thesis. I suppose this thesis is the contribution to clarifying the current situation of this issue. I believe that the topic of my thesis is up-to-date and that I managed to summarize the most significant information regarding this topic and fulfil the aims I set down. I would be very glad if my work led to the contemplation of this issue and subsequently to a more extensive propagation of the breast cancer prevention.

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.

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
