Image segmentation based on relief
Gros, Jan ; Špiřík, Jan (referee) ; Křupka, Aleš (advisor)
The aim of this labor is to introduce the technique of image segmentation by flooding relief of landscape (watershed method). There are described some methods of image segmentation and explained the basic operations of the images, from which the morphological operations are used for watershed segmentation. Part of this labor is a short passage that deals with the use of some image filters for image preprocessing. The result of previous knowledge is presentation of segmentation algorithm designed by Lee Vincent and Pierre Soille. The next section describes the algorithm implementation in Java, contents and function of each class module and implementation using RapidMiner. The last section presents the results of the segmentation with created module using the test images without and with the use of some selected filters to reduce oversegmentation and improve the resulting segmentation.

Design and realization of extrusion head and connecting members for extrusion of circular plastic profiles
Novák, Jakub ; Veselý, Oldřich (referee) ; Koutný, Daniel (advisor)
In this work is developed a proposal for extrusion head for extruding plastic wires of small diameter. There is a new conceptual design of cooling, which allows shape extruded products already in the extrusion head and thereby eliminates the need for large cooling tanks. To determine the optimal design is used software named Virtual Extrusion Laboratory, which is used in practice for the simulation of the extrusion process. Then it is experimentally determined behavior of plastic material, when the temperature of the melt in the extrusion head is reduced.

The principle of prevention in environmental law
Dvořák, Libor ; Damohorský, Milan (advisor) ; Stejskal, Vojtěch (referee) ; Pekárek, Milan (referee)
The principle of prevention in environmental law The principle of prevention as one of a common legal principles plays also a key role in environmental protection. Once the environmental damage occurs, the remedy is more costly in all aspects, including economical ones. Moreover, some damage can be irreversible. Thus, modern environmental law and policy is based on prevention. The implementation of the principle is not only reduced to pollution prevention, but in broad meaning, to damage prevention. In secondary legislation, the principle of prevention is realized primarily through general prevention obligation (Act on the environment, Waste act, Water act, Nature protection act etc.). Environmental impact assessment is the essential instrument for implementation of prevention principle in environmental law. The environmental assessment covers plans and programs (strategic environmental assessment, SEA) and individual projects (environmental impact assessment, EIA) likely to have significant adverse effects on the environment. The most important result of environmental assessment are mitigatory measures including measures to prevent or reduce any environmental damage deriving from the implementation of the plans and programs or projects. Waste prevention is also a typical field for application of the...

Social dialog in local government in the Czech Republic
Odvárková, Markéta ; Dvořáková, Zuzana (advisor) ; Kleibl, Jiří (referee)
The aim of this work is to describe the quality of social dialogue in local government in the area of Czech Republic, to find out if there is, in the presence of trade union in the local government institutions, a positive influence on civil servants working for local authorities and if the impacts on austerity measures realized are reduced. For this purpose, it is important to give a detailed description of a position and function that the local government in the public sector in the Czech Republic has and to clarify a position of civil servants working for local authorities. In this work, there is also described the system of social dialog and there are analyzed the social dialog institutions with the aim of the local government. In order to find out the trade union influence over the public servants working for local authorities satisfaction, it is carried out a survey at all levels of local government. It is found a little influence on the satisfaction that the trade unions have, resulting from a relatively poor labor union organized character. This situation is, in connection with austerity measures, one cause of the social dialog in the public sector ineffectiveness.

Implementation of Health Policy Reform in the Czech Republic.
RICHTEROVÁ, Andrea
The introduction of user fees and surcharges for medicinal products and foods for special medical purposes is considered to be one of the steps preceding the implementation of health policy reform. As of 1 January 2008, four basic fees were introduced in the Czech healthcare system with the objective of reducing unnecessary demand and misuse of health care. The objective of my Diploma Thesis was to map and evaluate the effects of the introduction of user fees on patients{\crq} number of visits to outpatient specialists. Three main objectives were formulated during my work on this thesis. The first objective was to provide a coherent overview of the issues related to the introduction and use of fees introduced on 1 January 2008 for outpatient specialists. The second objective was to compare patients{\crq} rate of visits to outpatient specialists with the year 2007. The third objective was to evaluate whether the patients{\crq} number of visits to outpatient specialists decreased in relation to age, gender, care provided, and kind of disease. Subsequently, four hypotheses were formulated. Hypothesis 1: The patients{\crq}rate of visits to outpatient specialists decreased compared to the year 2007 as a result of the introduction of user fees. Hypothesis 2: Compared to the year 2007, the introduction of user fees resulted in no considerable decrease in the rate of visits for patients with chronic diseases. Hypothesis 3: The impact of user fees on the rate of visits to outpatient specialists will be comparable for both genders. Hypothesis 4: The introduction of user fees will not result in a prolongation of the interval between the respective visits of patients to outpatient specialists. Quantitative research and method of questioning were used to achieve the goals and verify the hypotheses. The questionnaire technique was used for data collection. The research survey group for the questionnaire comprised physicians with outpatient specialties practicing in South Bohemia, Hradec Králové, Liberec,and Plzeň Regions, Capital City of Prague, Central Bohemia, Ústí and Zlín regions. The final research group comprised 79 specialist physicians with specialties as follows: allergology and clinical immunology, anesthesiology, dermatovenerology, gynecology, surgery, internal medicine, pneumology, ophthalmology, ENT, oncology, orthopedics, neurology, psychiatry, rehabilitation, and urology. The Diploma Thesis met its main objectives, as well as its partial objectives. The second, third, and fourth hypotheses were confirmed. The first hypothesis was not verified successfully in this research. The results of my research suggest that user fees had an impact on patients{\crq} rate of visits to outpatient specialists and can be used for publication in professional journals.
