Kontrast zrn na velmi nízkých energiích v REM
Pokorná, Zuzana ; Frank, Luděk
When lowering energy of incident electrons to 100 eV and less, the elastic scattering becomes heavily anisotropic while the inelastic scattering progressively drops off. Energy dependence of the reflected signal becomes then specific to the crystal orientation. The experiments with the imaging of the metal polycrystals were done in the SEM equipped by the cathode lens.

Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.

Access to Information and Access to Justice in Environmental Matters in the Republic of Irealand and the Czech Republic
Vítková, Martina ; Stejskal, Vojtěch (advisor) ; Sobotka, Michal (referee)
This diploma thesis deals with access to environmental information and access to justice in environmental matters introduced by Aarhus Convention in the specific conditions of Czech Republic and Ireland. These rights are considered to be very important tools for environmental protection. At a time when people threaten their own existence by negative interference with the environment it is necessary that effective means for its protection exist. These means are access to environmental information and access to justice in environmental matters, which together can be called as environmental procedural rights. The first chapter of this thesis presents the sources of environmental procedural law and observes the development of law at international, European and national level. The most important international document in this field is the Aarhus Convention that was adopted in 1998 by most of the European countries and that provides for access to environmental information, access to justice and public participation in environmental decision-making. This convention has largely affected the law of the European Union, where several directives has been adopted, including most importantly the Directive 2003/4/EC on access to environmental information and the Directive 2003/35/EC on public participation in...

Nurse in the Course of Time - the History of the Nursing Profession in the Czech Lands
KOPULETÁ, Martina
The aim of this thesis is to map the historic development of the nursing profession in Czech nursing from the past to the present. The Bachelor thesis is composed purely theoretically. The development of nursing profession is described in its important millstones. To gain information, it was necessary to peruse a considerable amount of bibliographic publications, research papers and internet sources. Further off the theoretical part was enhanced by memories of former nurses who used to work at hospitals after the World War Two and during the communist regime. The nursing profession has being formed since time immemorial and this process still continues. Wars, social and political situation, scientific progress and new knowledge in medicine had a great impact on the foundation of nursing. The nursing profession had to go through a very long, winding and sometimes even thorny journey to get the position of independent scientific discipline, as it is nowadays. The nursing profession routs of in the past. First part of the thesis deals with nursing in the period of the early Middle Ages and describes its first two stages. First stage in nursing dealt with lay nursing care which was performed by family members in their homes. Second stage, charitable nursing, came along with faith in God and Jesus Christ. The church caretakers tended the poorest and needy people in hospitals and poorhouses. A great development in nursing, that also means nursing profession and medicine, was during Crimean War. This period is known as third stage of nursing activity that is the organised nursing. We owe it to Florence Nightingale, Nikolay Ivanovich Pirogov and Jean Henry Dunant. These personalities of world nursing gave the nursing profession solid foundation and order. Next part deals with acquisition of professional skills. The origins of nursing education in this country were significantly influenced by emancipation movements in 19th century led by Eliška Krásnohorská and Karolína Světlá who fought for women's rights and education for women. We have to be grateful to these women for establishment of the first nursing school in Austria-Hungary which was founded in 1874 in Prague. The nursing profession gained importance by foundation of this school and professional aiming education of nurses started being to be formulated. During the time until the World War Two it was mainly members of religious orders who cared about the ill in our hospitals. Nursing education was procured by Česká zemská škola pro ošetřování nemocných before the establishment of Czechoslovakia. At the beginning of the First Czechoslovak Republic civil nurses and graduate nurses were gradually integrated into hospitals where they most frequently hold the position of nurses in charge. Further the Bachelor thesis is about social and working conditions of nurses at ward. The conditions, in which the patients were hospitalized, are described as well.Nursing profession in the course of World War Two (1939 - 1945) monitored a specific development. Nuns had to leave hospitals and were replaced by German caretakers. After the war German doctors and nurses were displaced back to Germany. This unfavourable situation was solved by the return of religious orders, but it did not last long. In the 1950´s they had to leave hospitals again and definitively forever.The bachelor thesis further describes the 1990´s which are the years of enhancing the quality of nursing care and led to gradual gaining of independence in the field of nursing.Finally, personalities of Czech nursing care that anyhow, mainly by their work, contributed to the establishment and development of nursing profession are mentioned at the end of the bachelor thesis.

Noise, Transport and Structural Properties of High Energy Radiation Detectors Based on CdTe
Šik, Ondřej ; Lazar, Josef (referee) ; Navrátil, Vladislav (referee) ; Grmela, Lubomír (advisor)
Poptávka ze strany vesmírného výzkumu, zdravotnictví a bezpečnostního průmyslu způsobila v posledních letech zvýšený zájem o vývoj materiálů pro detekci a zobrazování vysokoenergetického záření. CdTe a jeho slitina CdZnTe. jsou polovodiče umožnují detekci záření o energiích v rozsahu 10 keV až 500 keV. Šířka zakázaného pásma u CdTe / CdZnTe je 1.46 -1.6 eV, což umožňuje produkci krystalů o vysoké rezistivitě (10^10-10^11 cm), která je dostačující pro použití CdTe / CdZnTe při pokojové teplotě. V mé práci byly zkoumány detektory CdTe/CdZnTe v různých stádiích jejich poruchovosti. Byly použity velmi kvalitní spektroskopické detektory, materiál s nižší rezistivitou a výraznou polarizací, detektory s asymetrií elektrických parametrů kontaktů a teplotně degenerované vzorky. Z výsledků analýzy nízkofrekvenčního šumu je patrný obecný závěr, že zvýšená koncentrace defektů způsobí změnu povahy původně monotónního spektra typu 1/f na spektrum s výrazným vlivem generačně-rekombinačních procesů. Další výrazná vlastnost degenerovaných detektorů a detektorů nižší kvality je nárůst spektrální hustoty šumu typu 1/f se vzrůstajícím napájecím napětí se směrnicí výrazně vyšší než 2. Strukturální a chemické analýzy poukázaly, že teplotní generace detektorů způsobuje difuzi kovu použitého při kontaktování a stopových prvků hlouběji do objemu krystalu. Část mé práce je věnována modifikaci povrchu svazkem argonových iontů a jejímu vlivu na chemické složení a morfologii povrchu.

Acceleration of Object Detection Using Classifiers
Juránek, Roman ; Kälviäinen, Heikki (referee) ; Sojka, Eduard (referee) ; Zemčík, Pavel (advisor)
Detekce objektů v počítačovém vidění je složítá úloha. Velmi populární a rozšířená metoda pro detekci je využití statistických klasifikátorů a skenovacích oken. Pro učení kalsifikátorů se často používá algoritmus AdaBoost (nebo jeho modifikace), protože dosahuje vysoké úspěšnosti detekce, nízkého počtu chybných detekcí a je vhodný pro detekci v reálném čase. Implementaci detekce objektů je možné provést různými způsoby a lze využít vlastnosti konkrétní architektury, pro urychlení detekce. Pro akceleraci je možné využít grafické procesory, vícejádrové architektury, SIMD instrukce, nebo programovatelný hardware. Tato práce představuje metodu optimalizace, která vylepšuje výkon detekce objektů s ohledem na cenovou funkci zadanou uživatelem. Metoda rozděluje předem natrénovaný klasifikátor do několika různých implementací, tak aby celková cena klasifikace byla minimalizována. Metoda je verifikována na základním experimentu, kdy je klasifikátor rozdělen do předzpracovací jednotku v FPGA a do jednotky ve standardním PC.

Physically-based Modeling and Simulation
Dvořák, Radim ; Racek, Stanislav (referee) ; Šujanský,, Milan (referee) ; Zbořil, František (advisor)
Disertační práce se zabývá modelováním znečištění ovzduší, jeho transportních a disperzních procesů ve spodní části atmosféry a zejména numerickými metodami, které slouží k řešení těchto modelů. Modelování znečištění ovzduší je velmi důležité pro předpověď kontaminace a pomáhá porozumět samotnému procesu a eliminaci následků. Hlavním tématem práce jsou metody pro řešení modelů popsaných parciálními diferenciálními rovnicemi, přesněji advekčně-difúzní rovnicí. Polovina práce je zaměřena na známou metodu přímek a je zde ukázáno, že tato metoda je vhodná k řešení určitých konkrétních problémů. Dále bylo navrženo a otestováno řešení paralelizace metody přímek, jež ukazuje, že metoda má velký potenciál pro akceleraci na současných grafických kartách a tím pádem i zvětšení přesnosti výpočtu. Druhá polovina práce se zabývá poměrně mladou metodou ELLAM a její aplikací pro řešení atmosférických advekčně-difúzních rovnic. Byla otestována konkrétní forma metody ELLAM společně s navrženými adaptacemi. Z výsledků je zřejmé, že v mnoha případech ELLAM překonává současné používané metody.

A historical view of the army nurse profession.
PAVLÍKOVÁ, Andrea
The thesis deals with the profession of a military nurse. We can assert that the official study of military, non-medical health-care related qualifications and its use in practice not only for military purposes dates back to the fifties of the last century. However, women as health care professionals, consequently in uniforms, have always been an actual issue. The development of health care activities always existed, however, we must not neglect influence of scientific and medical findings. The historical timeline of development of medical care in the battle field was recorded and ranges from pre-historical healing. The way of Christian medicine was negatively influenced by the Catholic Church. The dark period of the Middle Ages had actually wrested medical performance from the hands of specialists and the suffering were left to the "tender" mercies of the priests. The following part of the thesis concerns modern medicine where enlightenment reforms were exercised. Some of the original six-month courses for military surgeons were organised in this period of time; they weretransformed into Military Surgical Academy, out of which the famous Josefinum originated. A expression of humanity which supported a form of health care of war veterans was demonstrated by constructing buildings for invalid people. The second half of the nineteenth century is characterized by the phenomenon of the presence of nuns in military hospitals. This study goes further in depth of professionally organized healthcare right in the battle field, which dates back from the era of wars in the Crimea.This stage describes the transformation of caring into nursing which requires the necessity of specialized preparation of persons providing nursing practice. In addition, Henry Dunant engraved himself into the history of the profession of a nurse, as the founder of the Red Cross, who first trained health care professionals for working within armed intentions of the state. The continuation of this action sketches out the process of providing first aid in principal armed conflicts of the twentieth century. It describes the functioning of commander operated military health service of that time. WWI drove Czech medical staff to both sides of the front where they provided medical help to the injured. Nurses of the WWII already performed their duties in uniforms as the rightful members of the army. The thesis also mentions post-war usage of military health care professionals in secret foreign missions and their specialized erudition.Last but not least, it marginally discusses contemporary possibilities of modern health care service of the Army of the Czech Republic. The goal of the endeavours of writing this thesis was to chart out clearly the development of the profession of a military nurse within the historical context, focusing mainly on women coming from Czech regions. In order to make the history background concerning specific female participants of the world war conflicts understandable to the reader, this paper reports, in broader extension, peculiar medical and nursing findings, already from the era of prehistoric civilisations. The history study method were applied for the purpose of the theoretical thesis. The methodology is based on searching, studying, sorting and the consecutive systematic objective describing of the events from the past times with the intention to propose comprehensive report on the subject given. It was necessary to study inexhaustible amount of sources to obtain awareness of historical connections. Factual information was derived by analysing of primary and mainly secondary documents. The thesis sketches out histories of military health care and the profession of a military health care professional stemmed from the exploration of appropriate written sources and conclusion of the basic findings. The intentions of the work are not only to clarify the past but also to contribute to solutions of every-day issues.

Supervision in psychiatric nursing
RŮŽIČKOVÁ NEUŽILOVÁ, Michaela
Basic theoretical background The theoretical part of the thesis explores the issue of supervision and focuses on psychiatric nursing. It is divided into several parts. The first part is focused on supervision, briefly characterizes supervision as such, then it describes its divisions, functions and methods. It also explores the participants of supervision, the agreement on supervision, transcultural supervision and Balint groups. The following part describes historical development of psychiatric nursing, briefly presents the personality of Joyce E. Travelbee. In the conclusion of the theoretical part of the thesis the problems of education and competence of nurses in psychiatric care are introduced, marginally mentioning the Turku declaration. The aim of the work The main aim of the thesis is to investigate the awareness of nurses working in psychiatric care of the clinical supervision options. The task of the second objective is to find out the opinion on supervision of nurses working in psychiatric care. The third objective is focused on means to assist nurses working in psychiatric care in their personal development and growth within their practices. The purpose of the fourth objective is to find experience with supervision of nurses working in psychiatric care. The methods used Qualitative investigation was chosen for the empirical part of the thesis. The method used for data collection was in the form of semi-structured interview. The interviews with the respondents were taken down using a voice recorder and transcribed, qualitative data was then analyzed by pencil and paper encoding technique and semantically organized into 27. groups of categorization. The selection of a research sample was intentional, consisting of twelve nurses working in psychiatric care in the Czech Republic. Results The research focused on nurses who do not have personal experience with supervision revealed that they have certain awareness of the supervisory process, however not quite sufficient to be able to describe the nature and function of supervision in its entirety. Their knowledge is rather theoretical. They understood supervision as help to solve disharmonious relationships in the workplace, as well as it could improve communication skills of the nurses, it would also assist in dealing with crisis intervention and prevent burnout syndrome. The results regarding nurses who do not participate in the supervisory process clearly indicated that they have insufficient support and the opportunity for both their professional and personal growth in their workplace, while this important could be solved by supervision. The research, which covered only nurses who have had personal experience with supervision and regularly participate in it, showed that their knowledge and skills related to the supervision process are quite sufficient to be able to understand and use supervision practically in the whole range. These nurses sees supervision as a benefit that would allow them not only to understood themselves, but also to learn how to manage challenging situations that are a part of their profession. Supervision gives them confidence, provides support and teaches them to deal with people who are part of their work process. Supervision has become a tool for preventing burnout and showed them how to use their own potential effectively. Conclusion This thesis is focused on the use of supervision in psychiatric nursing. Working with mentally challenged patients is very demanding, therefore supervision plays its justified role there. If you do not know yourself and you are not able to solve your own problems, you can never effectively and comprehensively address the problems of others, who are often desperately waiting for your help. The results will be presented at professional seminars designed not only to nurses working in psychiatric care.

Gluten-free diet - reality in school facilities
JIRÁČKOVÁ, Marie
The topic of this bachelor thesis is gluten-free diet - reality in schools facilities. The goal of this work was to determine the number of school cafeterias in the Vysocina Region which provide gluten-free meals, to evaluate awareness of the canteen staff about preparation of the gluten-free diet and to describe the cooperation between the school cafeteria and family of the pupil with gluten-free diet. School meals are important to provide optimal intake of nutrition during the time the child spends in school, to establish proper eating habits and to better integrate the child into the group of its peers. Gluten-free diet is a necessary medical precaution especially for those with coeliac disease, in which case gluten can lead to villous atrophy, and for those with gluten allergy for whom gluten intake can cause anaphylactic shock. Adherence to the gluten-free diet is recommended also to those with non-coeliac gluten sensitivity diagnosis, although gluten causes only short-term complications, usually intestinal. The method of quantitative and qualitative research was used to make this thesis. The research sample consisted of 8 school cafeterias from the Vysocina Region which provide gluten-free meal to their pupils. Awareness about gluten-free diet principles of the managers of the cafeterias or of the cooks responsible for preparation of gluten-free meal was determined by means of semi-structured interviews. The calculation of the two-day menu of each cafeteria by means of the Nutriservis Profesional program was also part of this thesis. The results were compared with the recommended daily intake of energy, proteins, fat, and saccharides for pupils of elementary and secondary schools. The results of the quantitative research show that gluten-free diet is provided by only a small percentage of school cafeterias in the Vysocina Region. The qualitative research prove sufficient awareness of the cooks about gluten-free diet, with awareness of those cooks directly responsible for preparation of gluten free meals being at much higher level. It was also determined that the cooperation with parents of pupils with gluten-free diet is a usually one time occasion limited to an arrangement of nonperishable gluten free meal packages.
