Kolařík, Vladimír ; Horáček, Miroslav ; Krátký, Stanislav ; Meluzín, Petr ; Chlumská, Jana ; Matějka, Milan ; Král, Stanislav
The paper presents planar diffractive structures with optical elements arranged in positions according to a phyllotactic model. Further, we discuss the creation of a diffractive phyllotactic pattern and its properties. One of the particular arrangements, a nesting of two different phyllotactic models possessing a different level of fineness, is described in details. The discussed arrangement of elements within a circle can be used also in the laser beam splitting application.

Human and social capital in primary education
KOKŠTEIN, Jiří
The thesis contains a theoretical insight into the studies that the issue of human and social capital involved from different perspectives, engage their evolution over time, their measurability, examine them, and complemented with other evidence. This part contains relation of human and social capital in relation to the aging of the human population and focuses on the human capital of older workers. Theoretical study ends with an insight into the basic education, the role of teacher and seeks to provide information on surveys already conducted in the area of education, which in the application of serve for me compared to the data obtained from the survey. The application part is focused on the teaching staff of primary schools. Education in currently globalized world, changing not only its content but also methods and forms of work. Irreplaceable role in this process is played by educators. To meet all the demands placed on them, it is essential that they pay close attention to their continuing education and sharing of acquired education, which is essential to the growth of human and social capital, because they are interacting. The work examines selected sample of teachers and approaches to this issue by detecting what is education motivates them whether they are satisfied with the benefits of educational events, what type of education they prefer etc. Working findings further analyzes looking for relationships between age and sex educators according to the hypotheses . Educator is someone who is in constant contact with other people. This of course also formalizes its attitudes and experiences. As a human being perceives the views of society and shapes on her own views, which it subsequently may influence the exercise of his profession. Therefore, in this part of the thesis is dedicated to exploring and bridging social capital, which determines the size of the circle of people with whom the teachers generally meet and interact. The last research that is possible to find thesis, it is perceptions of social status of teachers by themselves.

Green spaces in the city, their evolution and transformation on the example of Prague in 19th and 20th century
Kubecová, Barbora ; Klusáková, Luďa (advisor) ; Pokorná, Magdaléna (referee)
Green space is an essential part of the city urbanism. Research dedicated to development of the greenery and emergence of the first public parks contributes substantially to the understanding of urban issues and urban history. Green space has an aesthetic function, but is also a socially stratified space. Every city has its own unique greenery. It is not different in the case of Prague, whose dominant - Prague Castle creates unique linking of urban and green with Petřín and Malá Strana. The thesis "Green spaces in the city, their development and transformation on the example of Prague in the 19th and 20th century" aims to bring the historical development of Prague's greenery, especially the creation of public green space and point out the fact that people commonly accepted phenomenon of public parks was not always a matter of course. Development of green space, the struggle for its development and rescue, employed clubs, societies and individuals and has become one of the priorities for urban policy. Mainly the contemporary guides were used as a source for this work and for describing the emergence of the first public parks in the 19th century and the transformation of types of urban green areas. Other sources featured professional literature, contemporary book- published titles, memoirs, maps,...

The Role of Nurse in the Prevention of Disease of Civilisation
PAVLOVÁ, Martina
The current state Prevention is a complex care of a patient when we are trying to prevent from the occurrence or development of a disease, or when we want to prevent from its consequences and mitigate them. Recommendations for prevention set by a doctor must be on a scientific basis, and they must be a part of all branches of medicine. Their effectiveness depends on the cooperation between patients and medical staff. The basic and most efficient method of prevention is the health promotion and health education, which is closely associated with it. The term health promotion involves a set of activities and precautions for the purpose of making health better and sustaining it. Diseases of civilisation (hereinafter "DoC") are groups of diseases which are distinguished by their association to our lifestyles. Human body is more and more threatened from unfavourable influences of external environment, such as the quality of atmosphere, work environment and environment itself, the lack of physical movement, unhealthy diet, smoking, and alcohol consumption. The list of diseases of civilisation varies and changes together with our society and the development of our lifestyles. Among the most common or frequent diseases of current time are cardiovascular diseases, which involve atherosclerosis, hypertension, myocardial infarction, stroke, coronary artery disease and obesity. Furthermore, between civilization diseases include diabetes mellitus type 2 or cancer, etc. The goal of the thesis There are two goals set for this paper. The first goal was to find out what the role of a nurse in the prevention of diseases of civilisation was. The second goal was to find out what the above mentioned role of a nurse was from the point of view of patients. Methodology For the purpose of the research part of this thesis, qualitative research using semistructured interviews was carried out. Respondents were divided into two groups; the first one consisted of eight nurses working at internal medicine and neurological department of the hospital in České Budějovice and a nurse working in a private office of a general practitioner for adult patients. The second group consisted of eight patients of the above mentioned health facilities. Results According to our findings, nurses and patients have different oppinions on the role of a nurse. Nurses in disease prevention see themselves as an equivalent to a doctor when undertaking this practice and giving guidance. The patient speaks only to the nurse who emphasized what they were told by the doctor and reiterated the main points. They make available to them leaflets and brochures or Internet resources. In contrast, most patients see a nurse as a more important source of information than the doctor. Patients have the feeling that the doctor does not have enough time or does not want to be botherd with questions. Rather the patient turns to his nurse, which they sees as more appropriate and someone to whom they can confide in without bothering. Summary The goal of the thesis was to focus on prevention, DoC, and the role of a nurse in the prevention of such diseases, as well as to study this issue, look at it from the point of view of patients and nurses via the interviews carried out in this paper, and to analyse such information. Based on this analysis are published recommendations for nurses and patients.

Nutritional care about immobile patient on standard department of internal type
AMBLEROVÁ, Michaela
Nutritional care for immobile clients at a standard department of internal type becomes still more important, because nutritional care is important for maintaining good health and supporting quality of life. Nutritional status of immobile clients is very important to diagnose as early as possible in order to avoid all risks of potential complications. Adequate nutrition is also very important to maintain good mental health. The central objective of this work was to explore the specifics of nursing care in the field of nutritional care for immobile client at a standard department of internal type. Following this goal, three research questions were set up: How is the nutritional status of patients at a standard department of internal type assessed? What are the possibilities of application of nutrition for immobile client at a standard department of internal type? What are the specifics of nursing care in the fields of nutrition of immobile client at a standard department of internal type? The empirical part of the thesis was processed using qualitative research, which was realized through semi-structured interview technique. The interview contained 3134 questions, which focused on nutrition care for immobile clients on standard unit of internal type. The research sample consisted of nurses working in the standard department of internal type in the České Budějovice Hospital, a.s. Overall, this study leads to two findings, both positive and negative. Within the positive findings we can say that nurses provide adequate care in the application of nutrition per os. Negative findings relates to the fact that the interviewed nurses provide only basic care in case of the introduction of enteral and parenteral nutrition. They do not know more detailed specifics of enteral and parenteral nutrition. Based on this finding, we think it would be useful to organize regular seminars and trainings for nurses to expand their knowledge about this type of care, or at least remind it. This thesis can serve as an informational material for nurses in practice or students of other health professions. This work can serve also as a basis for further research.

Nursing procedures in taking blood pressure
SEDLÁKOVÁ, Tereza
By blood pressure is meant lateral pressure or the side pressure of a blood column on the side of a vessel. The pressure is created thanks to the action of heart as a blood pump. This pressure is not the same in different parts of the bloodstream. By the blood pressure is meant the arterial pressure or pressure in the artery, so the pressure in big blood vessels. The highest values are reached in the expulsion phase of the heart action, which is called systole. The lowest values are reached in the phase of filling heart chambers, which is called diastole. The sole nursing procedures required in the process of taking a blood pressure reading are many and all must be followed. This thesis is composed of a theoretical part and practical part. Introduction to the theoretical part is composed of the main terminology from the physiology of blood pressure. In the theoretical part we follow with division on hypotension and hypertension, which are the most common diseases related to blood pressure, with diagnosis and recommendation for treatment. This thesis also offers information about measuring blood pressure by the invasive and the non-invasive method. The theoretical part is focused on the importance of the nurse in the process of measuring blood pressure with emphasis on her knowledge and practical skills.

Pick´s disease and the specifics of the nursing care of a patient with this disease
KOPKAŠOVÁ, Lenka
Pick's disease is a degenerative-atrophic process that primarily affects the frontal and temporal lobes of the brain. Besides Alzheimer's disease, it is a lesser known form of dementia which affects people of younger age. Although the exact range of Pick's disease occurrence varies in the literature, the average reported age is between 50-60 years. The disease can change eating habits, cause emotional swings, inappropriate behaviour and sloppy appearance of the patients. The behaviour to others is often selfish, the patients are unable to listen to others and ignore their surroundings. Pick's disease is also characterized by inappropriate sexual behaviour. Globally, the number of dementia patients is still growing and according to expert guesses the increase will continue. Nursing care for patients with dementia is therefore becoming a very actual topic as dementia is called a quiet epidemic of our century. Nurses in their departments quite frequently encounter patients suffering from dementia of various origins at different stages of disability and the staff at healthcare facilities often regard these people as a burden. The aim of this thesis, which is called Pick's Disease and Specifics of Nursing Care for Patients with this Disease, is, based on the theoretical knowledge, to map definitions and diagnosis of Pick's disease, to define the needs of such a patient, and to list the most common problems in the nursing care. It focuses on people with dementia within medical facilities. For proper understanding of the problem, the thesis starts with the anatomy and physiology of the brain and the description of cognitive functions which are affected by the dementia syndrome and the definition of dementia. Based on the studied literature, dementia is divided according to various criteria. It has been found out that dividing dementia is not entirely uniform, but the essential facts and overall opinions of the authors do not diverge. Pick's disease belongs to a group of frontotemporal dementia and its position in this group has changed over time, as it is recorded in the literature. The thesis includes recommendations resulting from the studied literature in the approach to patients with dementia and emphasizes personal communication with the patients and empathetic and humane approach. Although medicine cannot prevent dementia, an early diagnosis of a specific type of dementia and correctly targeted treatment can increase the quality of life not only of the patients but also of their families. I have chosen this topic because I find it very current and interesting. During my nursing practice at the Surgery Department and Aftercare Department, I have met patients suffering from dementia and I did not know how to properly and efficiently communicate with them. For the theoretical part of my work, the methods of explanation, synthesis and induction on the basis of Czech and foreign information sources have been used. The most frequently quoted Czech authors in my thesis are doc. MD. Roman Jirák, PhD., the head of the center for diagnosis and therapy of Alzheimer's disease at the psychiatric clinic of the General University Hospital in Prague, the 1st Medical Faculty of Charles University. This thesis can serve as an informational and educational source both for nurses and the general public who may experience the disease within their families. It would be considered a great success if it helped nurses or family members to diagnose Pick's disease or other dementia at an early stage.

Účinky xenobiotik na oxidační stres, metabolizmus lipidů, integritu DNA a životaschopnost lidských buněk a rybích spermií in vitro
LINHARTOVÁ, Pavla
Pollution of the aquatic environment by inorganic and organic chemicals is a major factor posing a serious threat to the survival of aquatic organisms including fish. In addition balancing risks and benefits of fish consumption is nowadays an intensively discussed public health topic. Spermatozoa of almost all fish species are released into water environment where they can be directly exposed to various compounds, such as xenobiotics including toxic metals, prior to fertilization. In addition, exposure of parental adults to various xenobiotics may affect gamete quality, which may subsequently reduce fertilization success. On the other hand the advantages of eating fish are well-known, not only in the point that fish is a healthy source of protein and other nutrients, but eating contaminated fish may also confer various health benefits. Research over the past few decades has shown that the nutrients and particularly the n-3 fatty acids (FA) found in fish and seafood, are for examples protective against cardiac diseases and have a positive impact on brain development. The thesis provides a focus on two different cell model types. Firstly, human hepatocellular cells (Hep G2, ATCC) were used as in vitro tool for studying the effect of the intake of cadmium (Cd2+) contaminated fish on cytotoxicity, oxidative stress and fatty acid and phospholipid class compositions. Secondly, spermatozoa of one threatened species of fish, sterlet (Acipenser ruthenus) were used as in vitro model for studying effect of potentially hazardous xenobiotic compounds' occurring in open waters. Sperm from sterlet were exposed for 2h to environmentally relevant concentrations of DQ (0-150

Relationship between the coat colour and melanoma occurrence in horses
Hovorková, Kristýna ; Hofmanová, Barbora (advisor) ; Majzlík, Ivan (referee)
The literary review is divided into two main parts, the first part is dealing with the coloring of horses and their genetic base and the second part is dealing with melanoma formations of horses and their division. In the chapter about several color types of horses there is a description of forming basic color types which is done by three locuses: COLOR, EXTENSION and AGOUTI. Locus COLOR (CREAM) controls whether or not to create pigment. EXTENSION locus controls about the type of pigment and AGOUTI locus controls the distribution of pigment. The next subsection gives a breakdown of the white color in horses. Greying proces is related with locus GREY where there is a loss of pigment and the coat itself. This process and mutation is commonly connected with dermal melanoma. Non-pigmented spots called vtiligos are connected with the greying process, which is more intense with increasing age. Vtiligios are commonly found in grey horses, at the same locations as dermal melanoma. The places are perianal area under the tail, around the vulva, lips, eyes and around the penis. Melanoma formations are divided according to whether they occur in Grey horses or other colored horses and whether they have a benign or malignant potential. A further breakdown of melanomas at grey horses is whether it is a separate, smaller segments or large, associated lesions, when this condition is called dermal melanomatosis. At the end of the thesis there is a description of the treatment options for melanoma. The most effective appears to be a surgical removal of smaller formations. There were studies which have examined the anticancer action of the drug cimetidine but the results are not yet sufficiently conclusive. As preventing the occurrence of melanoma in grey horses it is appropriate to implement the necessary measures and individuals who are concerned should not be included in the next breeding.

Comparison of HPLC a GC-MS method for pesticide determination in soil
Chalbia Václavíková, Alena ; Kočárek, Martin (advisor) ; Havlík, Jaroslav (referee)
Physical and chemical properties of pesticides may vary significantly. Pesticides can be acidic, neutral or alkaline. Some compounds containing phosphorus, other sulfur, nitrogen or halogens. These atoms can be important for the detection of pesticides. Some of the compounds are volatile, others on the contrary not evaporate, which is also one of the important properties for chromatography. The diversity of pesticides actually makes it impossible to create a universal method, which is very impractical in terms of quality and time determination. Because that pesticides are one of the most chemicals in most countries. In the food and drinking water are limits on pesticides in order to avoid negative impact on public health. For residues in soil or surface water limits are set. (Lutz et al., 2006) The objective of this thesis is to evaluate the possibility of using two types of chromatographs with different detectors for the analysis of pesticide. Pendimethalin which was chosen for this work, will be analyzed usinga liquid chromatograph with UV detektor and gas chromatography with mass detector. Both this method will be compared as well two extraction methods (Soxhlet extraction and shaking), and two extraction agents (methanol and acetonitrile). Another point of the work is to provethe hypothesis that, for the determination of pendimethalin in soil is by gas chromatography using a mass spectrometer in comparison with the high performance liquid chromatography time and more expensive, but will achieve a higher yield and a lower detection limit of the pesticide.
