Environment in China - current state, problems and perspectives
Salačová, Aneta ; De Castro, Tereza (advisor) ; Neumann, Pavel (referee)
The problematics of the environment has been underestimated in China for a long time. This country has been developing with incredible speed in the last three decades. The price for such growth is the current state of the environment in China. The thesis is divided into three chapters. The goal of this thesis is to evaluate the current state of the environment in China and the development of the stance of the Chinese government towards the protection of the environment in the new millennium. In connection with the economic growth is analysed the dependence on air pollution and Chinese GDP. Last but not least are offered possible solutions and perspectives of the future development of air pollution in China.

Processing Differencies in Matters of Juvenile Perpetrators
KALIVODOVÁ, Martina
My bachelor thesis will concern criminal procedural law of juvenile offenders, focusing on the specifics of proceedings with juvenile offenders, which I shall compare to proceedings with adult offenders. In the introduction I will mention the history of criminal law with juvenile offenders, which has undergone significant changes. At first criminal law was only regulated by the penal code and by the criminal procedure, which only included provisions concerning juvenile offenders. This regulation was insufficient as it did not allow to reflect juvenile criminality. There were tries to enforce a new code of law, which would contain only juvenile justice. Quite recently, in the year 2004, because of growing juvenile criminality and the need to solve juvenile criminal cases differently, a new independent law n. 218/2003 Sb. on juvenile justice was created, with the full name of law n. 218/2003 on the liability of youth for unlawful acts and on juvenile justice and on change of some laws. This law brought many changes and represents a positive contribution in juvenile justice. In my work I will introduce the juvenile justice law and I will point out the facts resulting from it. At the beginning of my thesis I will shortly define the basic concepts dealing with substantive criminal law of juvenile offenders, which are distinct from the criminal law of adults, and the knowledge of which I consider necessary for full understanding of my work. The aim of my work is to highlight the differences in procedural criminal law, in criminal proceedings with juveniles. I will compare criminal proceedings with juveniles to those with adults, which differ in significant terms. I will focus on certain specifics, which I will describe, compare to general regulations and evaluate. To conclude, I will evaluate the current state of juvenile justice and provide my own opinion on this topic. I will describe certain drawbacks in the law and suggest their change. I will describe my own ideas about juvenile law.

Differences between men and women in the Czech labour market
Stroukal, Dominik ; Kadeřábková, Božena (advisor) ; Pavelka, Tomáš (referee) ; Němec, Otakar (referee)
This thesis consists of five articles that apply current world research on labor economics at the Czech Republic and confirms the significant differences between men and women in this market. It shows that gender has a significant influence on the preference on the labor market and, consequently, on employment and health. First, the thesis shows that preferences are relevant determinant of career and then we study the difference in preference of salary for men and women. Subsequently it shows that gender plays a significant role in explaining the relationship between homeownership, and unemployment, as well as unemployment and health. The first chapter was able to demonstrate that the preference for a career has a positive influence on the choice of career. The influence of higher education on prioritizing career proved to be positive and significant. Probability of a career choice is reduced by the presence of children, however, is not dependent on their number, which is contrary to the theory of preferences. The second chapter shows that Czech women prefer more non-monetary rewards than men. It has also been shown that people with university education are same in the preferences of non-monetary rewards regardless of the gender of the respondents, however, compared to the world's research, the Czech higher education increases this preference. It turned out that women prefer risk less than men. The third chapter demonstrates that although the housing market undermines labor mobility and employment in the Czech Republic at the regional level, therefore, that in regions with a higher rate of home ownership is higher unemployment, at the individual level, the owners of housing are unemployed are less likely. The estimates are significantly different for men and women. Men living in owner-occupied housing have a higher likelihood of employment than women. At regional level, however, this thesis shows that the high rate of home ownership increases unemployment for both men and women, in the long run only to women. The fourth chapter showed that men transition to homeownership reduces the likelihood of unemployment next year. For women, this relationship has proved to be insignificant. In addition, as insignificant showed the opposite relationship, the transition from unemployment to the newly acquired home ownership. The last chapter shows that the change in the working status to unemployment will increase in the future probability of worse health. Influence in less than two years, however, proved to be significant. An important conclusion is that men have a significantly stronger relationship between health and unemployment than women.

Kyzivát, Marek ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis describes the initial state of the computer network Basic Schools and Kindergartens Ohradní (ZŠMŠ Ohradní) in Prague 4 and then its reconstruction, which I largely contributed. ZŠMŠ Ohradní consists of four pavilions and from one building on the other side of the street. The aim of this study is to assess the initial state of the network and point out the shortcomings that we discovered. We found deficiencies in the operation stress tests, measurements and data cabling overall analysis. Original networks connectivity was 100Mb/s. Together with a colleague, we are network administrators. Furthermore, I am going to introduce a new form of network, which has identified deficiencies improved, by using on newer technologies. I will describe its structure, address allocation, active and passive components, and operated services. New network is capable of 1Gb/s, and its spine is going to be 10Gb/s soon. Benefits of this reconstruction is faster, more stable and more modern network that will facilitate the work of employees of ZŠMŠ Ohradní. To these improvements, I have mainly contributed by measurements. I participated in the design and implementation of new form of data network. I collaborated with fellow Poc to the configuration of active elements and network services in reconstructed network.

Libantová, Silvia ; Indrová, Jarmila (advisor) ; Chaloupka, Radek (referee)
Tourism contributes to the prosperity of destinations by bringing financial resources, new jobs, a higher level of services and infrastructure development. However, if tourism does not develop sustainably, it is accompanied by negative factors, as well. Especially, negative impacts on the environment, such as: water and soil contamination, increased noise and overcrowded destination during the high season. As a response to the worsening state of the environment and possible irreversible changes caused by irresponsible human behavior, the idea of sustainable development is becoming more important. The theoretical part describes tourism in the Slovak Republic and highlights plans for sustainable tourism development. In the practical part, the results of the questionnaire, related to the awareness of sustainable tourism in the Slovak Republic, are evaluated. The main objective of this thesis is to evaluate the current situation in the field of sustainable tourism and to make suggestions for its future development.

INFLUENCE OF LASER CUTTING AND PUNCHING ON MAGNETIC PROPERTIES\nOF ELECTRICAL STEEL M470-50A
Bulín, Tomáš ; Švábenská, Eva ; Hapla, Miroslav ; Ondrůšek, Č. ; Schneeweiss, Oldřich
Electrical steel M470-50A belongs to the most often used materials in electrical machines. Due to this fact, it is desirable to know the magnetic parameters after processing raw sheets into the required shape. Basic parameters of mechanical, electrical, and magnetic properties of the sheets are usually obtained from the producer but the magnetic properties are changing in dependence on additional machining processes. The aim of this study is to describe changes in parameters of magnetic behavior after punching, laser and spark cutting of the original sheets. The basic information of structure was obtained by optical and scanning electron microscopy. The magnetic parameters were acquired from the measuring of magnetic hysteresis loops in dependence on saturation fields and frequencies. The results are discussed from the point of view of applied\ncutting technology with the aim to obtain the best magnetic parameters and consequently a higher efficiency of the final product. Results can be used as input parameters in simulation of the electrical machine.

Fytochemical potencial of polyfenols contain in berries
KRUMPHANZLOVÁ, Iva
This thesis sums up findings on polyphenols and their positive influence on human health. In these fytochemicals, unlike in micronutrients, recommended daily amount cannot be estimated. Micronutrient deficiency in food can cause deficiency symptoms, while in polyphenol deficiency, the deficiency does not occur. When they are present in sufficient amount in food, it is considered functional food, which is important for civilization illnesses prevention. At the beginning of the theoretical part, the polyphenol classification from pharmacological and chemical point of view is represented. On the basis of this classification important role of antioxidants and flavonoids is described. Special attention is being paid to resveratrol, which is populardue to its well known "French paradox". The following part considers the polyphenol influence on human health. The way in which polyphenols protect our body from certain diseases is explained in detail. Most of the health benefits are supported by studies conducted on animals. These studies are also mentioned and described in this paper. In the theoretical part the process of absorption and the polyphenols safety for human body is also explained. Polyphenol sources are listed in the last subchapter. The work is mainly aimed at blueberry fruits (Vaccinium myrtillus) and vine grapes (Vitis vinifera). Other berries are briefly mentioned as well, such as cranberries, raspberries, blackberries and currant. The goal of this work is to create a diet that would provide a functional daily amount of polyphenols. This amount can be compared to 120 ml of native blueberries. Only products, consumable without cooking, are used in this diet. The second goal is to chart, which food products are adequate source of polyphenols. On the basis of these goals, research inquiries were defined. Research inquiry No. 1: What amount of polyphenols is contained in berries, especially blueberries. Research inquiry No. 2: Which food products (without cooking) are ideal to be included in diet, to provide adequate daily amount of polyphenols. To asses polyphenol content in blueberries, analysis of polyphenol content acquired through GEOMED program from Nemocnice České Budějovice a.s., department of clinical pharmacology, was used. Assessments were made using the HPLC method (high performance liquid chromatography) in cooperation with the biological centre AV ČR in České Budějovice. Thanks to this analysis, the first inquiry can be answered. An interesting phenomenon is discovered, that frozen blueberries have higher polyphenol content then cooled ones. Malvidin (malvidin-3-6"-acetoyl glycoside) was chosen as priority anthocyan since it is most represented in the blueberry. Remaining information about polyphenol content in certain food products were drawn on Joseph Maroon´s book, MD, FACS (2010). The practical part involves a diet for 14 days, which meets the given requirements. The results clearly show that it is possible to create a diet rich in polyphenols. A list of blueberry products accessible to everyone is included. Blueberry dairy products, jams, beverages, fruit salads and fruit pyre have been analysed. The list shows which product contains the most polyphenols. The required amount can be achieved by the proper combination of given products. The ideal one proved to be 200 ml of red wine and one blueberry dairy product (with the malvidin value higher than 64). Findings in this paper will serve to promote polyphenol awareness and itseffects. This diet can be used in nursing homes, where their positive influence on equilibrium can be applied. It can also be used in spas and other alimentation related facilities.

Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic
HALÁSZOVÁ, Monika
Bachelor Thesis called "Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic" deal with the intake of dietary supplements containing iodine and intake of other significant dietary sources of iodine in relationship to saturation with iodine in the monitored group of 300 children aged 11-12 years . The thesis is divided into theoretical and practical part. Theoretical part deal with established issues in light of current situation and uses the knowledge of specialized literature in these areas: iodine and his dietary sources, influence of deficient or excessive intake of iodine on thyroid gland and its function, and also the solution to iodine deficit in Czech Republic. The thesis also deals with dietary supplements and nutrition of school-aged children. Practical part is focused on quantitative research. This research was done on selected group of children who had low level of ioduria (iodine in urine) according to State health institution. Statistical file included 300 children of both gender in age from 11 to 12 who live in Czech Republic. The reason why children of this age were chosen is because of importance of optimal intake of iodine in period of physical and sexual evolution. The children were divided into two groups. One group had ioduria up to 300ug/l and the second group had ioduria over 300u/l. Data were collected through questionnaire. Because of age of respondents, the questionnaire was filled in presence of at least parent. The questionnaire should have also served to parents as information about iodine importance for their children. The individual evaluation of ioduria and questionnaire was given to parents upon their request. Collected data were evaluated in Microsoft Excel. In practical part, two main goals and two research questions are set. Their task is to determine the rate of usage of dietary supplements with iodine and to find out what significant sources of iodine the children with ioduria over 300u/l take in. The milk and milk products, salt with iodine, salted delicacies, sea products and dietary supplements with iodine were observed as probable main sources of iodine intake. The first goal was to find out the amount of iodine intake from dietary supplements for previously mentioned group of children. The second goal was to find out if the dietary supplements with iodine (or any other combination of food rich on iodine) are used by observed individuals with ioduria over 300u/l. The results of research show if the respondent's level of ioduria is affected by in taking the dietary supplements or food with significantly higher content of iodine. My own research proved relatively frequent (but irregular) intake of dietary supplements with iodine by whole examined population. On the other hand, usage of dietary supplements with iodine is probably not correlated with usage of table salt without iodine or with thyroid gland illness by individual respondent or in his family. The milk and milk products and table salt with iodine proved to be the main source of iodine. According to research, children with excessive ioduria consume sources of iodine as frequent as other children. Deeper insight into results shows that reason for excessive saturation with iodine is combination of intake of dietary supplements as well as other significant food sources of iodine, especially milk and its products. By several respondents, the higher level of ioduria can be caused by higher consummation of sea products or by usage of dietary supplements with iodine in last two days. The need for better awareness about suitable rate of iodine dietary supplements intake as well as medical importance for lowering the amount of (iodine) table salt in food was discovered by research. The optimal supply of iodine by higher percent of observed population could be also achieved by optimizing the content of iodine in milk.
