Soukupová, Eva ; Příhoda,, Jiří (referee) ; Sokolář, Radomír (referee) ; Michoinová,, Dagmar (referee) ; Rovnaníková, Pavla (advisor)
The doctoral thesis deals with the reactivity of burnt clays in connection with modified lime mortars. The theoretical part of the doctoral thesis provides an overview of the properties of lime mortars, their quality and ways of their degradation. The different types of burnt clays (brick powder, bentonites and burnt clay shale), their origin, properties and factors affecting their reactivity and methods of its evaluation are stated. The properties and reactivity of burnt clays are evaluated on the basis of determination of pozzolanic activity, mineralogical and chemical composition, surface area, density, content of the amorphous phase and granulometry in the experimental part of the doctoral thesis. The compositions of lime mortars containing burnt clays and evaluation of an impact of burnt clay on the properties of mortars in the fresh and hardened state are given. Consistency, bulk density, workability and air content of mortars in the fresh state are evaluated. Strength characteristics depending on the time, water absorbability, porosity, capillary attraction, adhesion, coefficient of diffusion resistance, frost resistance, shrinkage, mineralogical composition and microstructure of mortars in the hardened state are evaluated. Attention is also paid to the influence of the cellulose ether addition into the modified lime mortars.

Possible ways to breach the water supply system a draft of the measures to prevent its abuse in South Bohemia.
SOUKUPOVÁ, Eva
The theoretical part of the thesis focuses on the characteristics of water as the basic structural element of the life on the Earth. It also mentions regulations related to critical infrastructure, water protection and water management. It describes water management system of the Czech Republic and the South Bohemian Region. It similarly characterizes the most probable chemical, biological or radiological water contaminants that might be abused by a man in the case of trespassing into waterworks system objects. The aim of the thesis was to map possible threats to the waterworks system and to propose follow-up measures preventing the South Bohemian Waterworks System from abuse. Upon identification of possible threats in the territory of South Bohemia and from the point of view of the extent of the thesis the text then focuses on intentional threat of waterworks object by a man. The research part first deals with more detailed description of the South Bohemia Waterworks System, from drinking water via its pumping, treatment, storage to its supply to final consumers. The system of drinking water supply to inhabitants of South Bohemia is divided into sectors by means of AKIS method here. A questionnaire to employees working in the water management sphere was based on this division and particularly vulnerability and the level of security measures in the individual South Bohemian Waterworks System sectors was evaluated from the information based on their answers. In the second plan the research part of the thesis focuses on description of security elements used in South Bohemian Waterworks System objects accompanied by my own photo documentation of objects and areas administered by the South Bohemian Waterworks Union. The elements of passive and active protection used by the South Bohemian Waterworks Union are documented and described here. Application of two operation analysis methods relates to this part. Quantitative research of security of waterworks objects based on evaluation of the best secured object of the South Bohemian Waterworks System was first performed. The obtained results enable us to determine which of the South Bohemian Waterworks System premises has the best active and passive security against trespass of unauthorized persons. To assess relevancy of the quantitative security research the method of relative comparison of waterworks objects security and its consequent interpretation by the security index is also used. The security index describes object protection against possible trespass within the whole area of the object. Application of this method brings numeric interpretation and identification of the overall security of the South Bohemian Waterworks System with regard to preference of the monitored parameters. The same result is achieved by both the methods. The applied operation analysis methods have revealed that the heart of the South Bohemian Waterworks System, the Plav drinking water treatment plant, the only drinking water treatment plant of South Bohemia supplying majority of South Bohemia inhabitants with drinking water, is the best protected object. Pumping stations and water towers are further well secured objects. There are also completely unsecured object in the South Bohemian Waterworks System. The conclusion contains some measures that should prevent unauthorized persons from trespassing into all waterworks objects and thus protect drinking water against contamination. As the observation has revealed the protection of waterworks objects should be improved with regard to the worsening safety situation in the world. This also involves the costs the South Bohemian Waterworks Union should invest in security to introduce the most up-to-date security elements into practice. We may conclude that the major part of waterworks objects are secured against abuse both passively and actively.

Comparison of anti biological protection of the CR with selected EU countries
SOUKUPOVÁ, Eva
Comparison of anti biological protection of the CR with selected EU countries The system of application of hygienic-epidemiological measures within the Czech Republic is based on Act No. 258/2000 Col. on public health protection and on modification of some related acts defining the system of the public health protection bodies and on Directive No. 440/2000 Sb. stipulating the conditions of prevention of occurrence and transmission of infectious diseases and hygienic requirements for operation of healthcare facilities. The individual tasks given to the public health protection bodies as well as to the Integrated Rescue System units may sometimes be misunderstood. These tasks must be known so as the set goals can be performed and thorough hygienic and epidemiological measures can be ensured. Each state has its own biological security system, which very often differs from that of the Czech Republic. To be able to ensure civil protection in the Czech Republic it is necessary to know the legislation provision or the system of biological agent detection in neighbouring countries, i.e. in Slovakia, in Germany, in Austria and in Poland, to make the cross-border cooperation more effective and reliable. The thesis compares the methods of anti-biological protection in the Czech Republic and in the neighbouring states. The thesis also provides information on the differences in legislation and in anti-biological protection application, from both, the basic as well as professional points of view. Upon these comparisons and upon set criteria a conclusion has been drawn that the Czech Republic is ready to cope with an attack by means of B-agents and that some country has more elaborated protection.

Rights of Immigrants
SOUKUPOVÁ, Eva
The Czech Republic encounters problems of immigration after 1989. At present time there are about 2.5% of foreigners in the Czech Republic. This percentage is amongst the lowest within EU, however the predictions for the future are that the number is going to constantly increase. People come to the Czech Republic seeking better conditions for living and want to start a new life here. Therefore part of the government policy should be securing immigrants with equal access and equal opportunities in the labour market, in relation to health as well as social care. A quantitative research in the form of a questionnaire technique was selected in the practical part. Anonymous questionnaires for immigrants and public were used. The research aimed at immigrants was conducted in institutions engaged in helping aliens in Brno, České Budějovice, Hradec Králové, Plzeň and Prague. Total of 120 questionnaires were sent out. The questionnaire's returnability was 49%. The research set was therefore formed by 59 respondents. Research aimed at public was conducted in České Budějovice, Jindřichův Hradec and in Třeboň. Total of 110 questionnaires were handed out and their returnability was 100%. All questionnaires were evaluated and elaborated into percentage figures. Two goals are set in the thesis. To each of the goals two hypotheses were set. Goal 1: Find out the level of immigrants' knowledge about labour law and related regulations to it {--} health insurance, welfare. Hypothesis No. 1: More than half of the questioned immigrants know their rights. Hypothesis No. 2: More than half of the questioned immigrants know to whom they may turn to in case of problem solving. After questionnaire evaluation the first hypothesis was not confirmed and the second hypothesis was confirmed. Goal 2: Find out the level of public awareness of the law status of aliens living in the area of the Czech Republic. Hypothesis No. 1: More than half of the questioned respondents do not know the alien rights living in the area of the Czech Republic. Hypothesis No. 2: More than half of the questioned respondents know the organizations providing support for aliens living in the area of the Czech Republic. After evaluation of the questionnaire the first hypothesis was not confirmed and the second was confirmed.
