The Controlling Study
Herda, Tomáš ; Mikovcová, Hana (advisor) ; Herda, Zdeněk (referee)
The main goal of this Diploma´s Thesis is to make a model for calculation of water and sewer rates for the company Vodovody a kanalizace Náchod, a.s. when sticking to the set criteria both from the side of VaK Náchod, a.s. and law regulations. Based on the theoretical part an analysis of customer sensitivity to the price changes using the data for last 20 years follows. Findings from the first two parts are used in risk analysis in next part. The created model calculates the water and sewer rates based on the information from the company accounting system in the way to generate sufficient financial resources to fulfill the renovation plan of infrastructural property plant and equipment and to transfer given amount to the company funds. In addition, the model monitors whether the legal condition of maximal allowable increase of profit per m3 is met. In the customer sensitivity to the price changes part the price elasticity of demand for water and sewer rates is calculated based on the data from 1995 to 2015. The assumption of inelastic demand is confirmed. Risk analysis part is deals with potential risk regarding the demand and prices. Potential impacts for the most significant risk are quantified. The analysis uses knowledge gained in the first two parts. It was confirmed that potential risks are exiting but do not have any significant impact on the going concern of VaK Náchod, a.s. The created model has been already used for the calculation of prices for the year 2017. Customer sensitivity analysis to the price changes and link to the potential risks is an additional information for VaK Náchod, a.s. which validates that nowadays, there are no significant threats which could affect the demand and water and sewer rates significantly.

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.

The topic of this dissertation thesis is collection, analysis and evaluation of information about investment decisions making within public administration bodies. The investment decision making is examined in relation to allocation of public funds on investment activities and projects. The main goal of this thesis is to analyze and evaluate the current status of the investment decision making within the public sector. Subsequently the goal is to offer new or updated knowledge related to these issues, and bring recommendations to improve the investment decision making of public administration bodies. At first, there are described current knowledge in the field of investment decision making. This is followed by an analysis of assessment methods used for evaluation and selection of investment projects. The work is completed by recommendations for investment decisions making in the form of a normative model. The model should increase benefits of public investment expenses for society. There are used data obtained through a questionnaire survey of 430 subsidized firms, 169 state organizational units and state funds and 130 cities, boroughs and counties. Another important source of information was secondary data of selected ministries and agencies, legislation and literature.

Use of Interest Rate Models for Interest Rate Risk Management in the Czech Financial Market Environment
Cíchová Králová, Dana ; Arlt, Josef (advisor) ; Cipra, Tomáš (referee) ; Witzany, Jiří (referee)
The main goal of this thesis is to suggest an appropriate approach to interest rate risk modeling in the Czech financial market environment in various situations. Three distinct periods are analyzed. These periods, which are the period before the global financial crisis, period during the financial crisis and in the aftermath of the global financial crisis and calming subsequent debt crisis in the eurozone, are characterized by different evaluation of liquidity and credit risk, different relationship between financial variables and market participants and different degree of market regulations. Within this goal, an application of the BGM model in the Czech financial market environment is crucial. Use of the BGM model for the purpose of predicting a dynamics of a yield curve is not very common. This is firstly due to the fact that primary use of this model is a valuation of interest rate derivatives while ensuring the absence of arbitrage and secondly its application is relatively difficult. Nevertheless, I apply the BGM model to obtain predictions of the probability distributions of interest rates in the Czech and eurozone market environment, because its complexity, direct modeling of a yield curve based on market rates and especially a possibility of parameter estimation based on current swaptions volatilities quotations may lead to a significant improvement of predictions. This improvement was also confirmed in this thesis. Use of swaptions volatilities market quotations is especially useful in the period of unprecedented mone- tary easing and increased number of central banks and other regulators interventions into financial markets that occur after the financial crisis, because it reflects current market expectations which also include future interventions. As a consequence of underdevelopment of the Czech financial market there are no market quotations of Czech koruna denominated swaptions volatilities. I suggest their approximations based on quotations of euro denominated swaptions volatilities and also using volatilities of koruna and euro forward rates. Use of this approach ensures that predictions of the Czech yield curve dynamics contain current market expectations. To my knowledge, any other author has not presented similar application of the BGM model in the Czech financial market environment. In this thesis I further predict a Czech and Euro area money market yield curve dynamics using the CIR and the GP models as representatives of various types of interest rates models to compare these predictions with BGM predictions. I suggest a comprehensive system of three criteria, based on comparison of predicti- ons with reality, to describe a predictive power of selected models and an appropria- teness of their use in the Czech market environment during different situations in the market. This analysis shows that predictions of the Czech money market yield curve dynamics based on the BGM model demonstrate high predictive power and the best 8 quality in comparison with other models. GP model also produces relatively good qua- lity predictions. Conversely, predictions based on the CIR model as a representative of short rate model family completely failed when describing reality. In a situation when the economy allows negative rates and there is simultaneously a significant likelihood of their implementation, I recommend to obtain predictions of Czech money market yield curve dynamics using GP model which allows existence of negative interest rates. This analysis also contains a statistical test for validating the predictive power of each model and information on other tests. Berkowitz test rejects a hypothesis of accurate predictions for each model. However, this fact is common in real data testing even when using relatively good model. This fact is especially caused by difficult fulfilment of test conditions in real world. To my knowledge, such an analysis of the predictive power of selected interest rate models moreover in the Czech financial market environment has not been published yet. The last goal of this thesis is to suggest an appropriate approach to obtaining pre- dictions of Czech government bonds risk premium dynamics. I define this risk premium as a difference between government bond yields and fixed rate of CZK IRS with the same length. I apply the GP model to describe the dynamics of this indicator of the Czech Republic credit risk. In order to obtain a time series of the risk premium which are necessary for estimation of GP model parameters I firstly estimate yield curves of Czech government bonds using Svensson model for each trading day since 2005. Resulting si- mulations of risk premium show that the GP model predicts the real development of risk premiums of all maturities relatively well. Hence, the proposed approach is suitable for modeling of Czech Republic credit risk based on the use of information extracted from financial markets. I have not registered proposed approach to risk premium modeling moreover in the Czech financial market environment in other publications.

Assessment of devices used by the Armed Forces of the Czech Republic in case of radiation emergency.
LOŠKOVÁ, Romana
This Thesis deals with the option of employing the Armed Forces of the Czech Republic (ACR) when a radiation emergency is imminent. Primarily, it focuses on evaluation of selected devices designed for radiation reconnaissance; summarising of radiation protection related legislation; and study of approved procedures. At its beginning, this Thesis tracks the origin of early detection systems at the territory of the then Czechoslovak Socialist Republic and their gradual evolution into the the existing form. From the radiation emergency point of view, this nationwide system represents a priceless help for monitoring of radioactive contamination dispersion and for warning. The following part sums up basic information on what is an ionizing radiation, how it comes into being and which basic quantities describe it. This part also contains basic type distinction, description of consequences for human organism and the most significant interactions of sources of ionizing radiation that could be misused with the most probability. This specific topic is introduced here because of the subsequent part of this Thesis being named Radiological Dispersion Device, or the dirty bomb. The significant part of this Thesis is the summary and classification of related legislation. The first documents referred to are two international standards. Publication 103 the 2007 Recommendations of the International Commission on Radiological Protection is dealing, inter alia, with dosing limits determining dose levels in planned exposure situations and reference levels used for emergency exposure situations and existing exposure situations. Publication 96 Protecting People against Radiation Exposure in the Event of a Radiological Attack is more substantial for this Thesis since it partly copes with the protection of front-line units including Integrated Rescue System (IRS) components and it specifies maximum exposure time for intervening personnel. Based on the IRS Catalogue of Typical Activities (STC 01/IZS), Materialised and Verified Use of a Radiological Weapon, the ACR would be one of the intervening components in such an attack. This Thesis analyses in detail individual ACR procedures starting with activities before employment, through threat prevention, event reaction to post-event activities like decontamination followed by monitoring of personnel contamination and their health condition. The practical part deals mainly with one of the Thesis´s goals which was evaluation of selected dosimetric devices used by the military for radiation reconnaissance. For this purpose, the quantitative research processing their main parameters was applied. The analysis within a selected sample was used for comparing and the sumary index IVi then showed the status of device applicability for contemporary use in radiation emergency. The pre-defined goals of this Thesis have been met implementing the above methods. The comparison of individual devices and their evaluation in respect to their applicability in joint radiation emergency operation with other IRS components has been carried out via discussion. It has been found out that some of the devices are obsolete and do not comply with the requirements for this job. This fact reflects the reality that these devices were designed in the period of a potential nuclear war. This corresponds with their robust structure and high level of sensitivity which is not desirable for a radiation emergency. The most severe problem, however, seems to be the fact that some devices measure quantities in old, no more used, units which could cause misinterpretation. On the other hand, other devices are modern, sensitive at low levels of dose input and offer real-time information on a well organised LCD display. To answer the question of ACR´s readiness to intervene in a radiation emergency one has to say that the ACR is ready to meet its rescue and consequence management tasks at a satisfactory level.

Freedom of Expression and Censorship on the Internet and Social Networks
Reindl, Jan ; Čermák, Radim (advisor) ; Sova, Martin (referee)
This thesis is focused on freedom of expression and censorship on the internet and social networks. Its goal is to evaluate current situation of censorship of the internet, to describe the most often used methods of censorship and suppressing free speech, as well as methods of its circumvention. The thesis is focused on the progress of internet censorship in its shift from a tool of governmental domestic network control into a tool in the hands of multinational organizations. Some focus is also given to the importance of anonymity as a way to freedom of speech, and to the analysis of current situation and possible future outcomes. This thesis is divided into five chapters. The first one serves as an introduction into the problematics. Second chapter describes methods of internet censorship, the third one describes its circumvention. The fourth chapter looks into the current situation regarding the role of social media in terms of internet censorship and possible results of censorship as well as future evolvement. Fifth and last chapter is dedicated to research of anonymous parts of internet community that could otherwise face censorship.
