On possible approaches to detecting robotic activity of botnets
Prajer, Richard ; Palovský, Radomír (advisor) ; Pavlíček, Luboš (referee)
This thesis explores possible approaches to detecting robotic activity of botnets on network. Initially, the detection based on full packet analysis in consideration of DNS, HTTP and IRC communication, is described. However, this detection is found inapplicable for technical and ethical reasons. Then it focuses on the analysis based on network flow metadata, compiling them to be processable in machine learning. It creates detection models using different machine learning methods, to compare them with each other. Bayes net method is found to be acceptable for detecting robotic activity of botnets. The Bayesian model is only able to identify the botnet that already executes the commands sent by its C&C server. "Sleeping" botnets are not reliably detectable by this model.

University of South Bohemia students' knowledge of the first aid theory
MALANÍKOVÁ, Jana
This work is separated into two main parts, the theoretical part and the research. In the first part the reader is familiar with teoretic knowledge of the first aid. I thought it is absolutely necessary to mention here the definition of the first aid , basic first aid theory consisted of the laic aid and the technical one. This work also correctly describes the latest techniques of cardiopulmonary resuscitation at adults . The second chapter is a small reminder of a history of the Red Cross. This chapter contains information about the beginnings of the Red Cross, as was the case with the founding of the Red Cross in the Czech Republic, dats about the International Movement of Red Cross and Red Crescent Societies and basic information about the possibillities of the first aid training. The fourth chapter is devoted to the basic principles of treatment for some life -threatening conditions such as: shock, unconsciousness, fractures, bleeding and how to call EMS. To learn about the accessibility and the clarity of the information of the first aid at the same time, I tried to borrow from the various information sources. According to the information, I decided to include above- mentioned theory in the theoretical part of the work. The second part relates the research , which has been established for one primary objective : to find out knowledge of the theory of the first aid. The research was conducted at selected colleges JCU, questionnaires were completed by 159 students. I chose respondents from these faculties intended to find the information just at these students because they represent a particular age group but also the various sectors of human activities. I further modified the sample random with the same proportion of students from the various faculties in the number of 100 respondents. There was chosen a quantitative method for this research. The necessary dats were collected by using an anonymous questionnaires. A structured questionnaire (see Appendix 1) contained a total of 22 questions focused on the theoretical knowledge of the first aid of JCU student. I processed the dats to confirm or refute the hypotheses in advance. Evaluation of dats was carried out using statistical random selectio , contingency tables and the results were set out neatly into the graphs. The results were processed in the Microsoft Office Excel 2010 programme. The statistical evaluation of the research has shown that the average knowledge of all faculties are balanced.

Honc, Adam ; Strouhal, Jiří (advisor) ; Smrčka, Luboš (referee)
The aim of this thesis is to determine the market value of joint-stock company MSV Metal Studénka for 31. 12. 2015. The thesis is divided into theoretical-methodological and practical part. The former contains the definitions of terms, techniques and methods which relate to not only the problems of company appreciation but also insolvency law focusing on corporate restructuring. In the practical part, the theoretical groundwork is applied. After the initial introduction of the company including a brief description of the course of insolvency proceeding, a strategic and financial analysis is conducted. After the evaluation of the company's financial health and future perspective, a division of assets into operationally necessary and unnecessary, analysis and value generator prognosis, financial plan formulation and the evaluation itself follow. For the final company appreciation, the discounted cash flow method in the variant of free cash flow to the firm (FCFF) is used.

Using of the Care benefit by Users of Social services
ŠINÁKLOVÁ, Marie
The bachelor thesis deals with the widespread social benefit, the attendance allowance and problems associated with it, which implies the main objective of this work, to find out how or what for this allowance is used. This thesis consists of a theoretical and a practical part. In the theoretical part I focused mainly on the purpose, the principles and basic functions of the allowance. I have also described who is and who is not entitled to the allowance, and when such entitlement may extinguish. In this part, I also focused on what the allowance is intended for and what it has to be properly utilized for. Furthermore, I mentioned in my thesis the inspection in accordance with the Social Services Act and the means of protection applied by the state in order to prevent the abuse of the allowance. In the theoretical part, I also mentioned the history of this allowance when it still was an allowance for attending a close person. Due to the fact that the attendance allowance is intended for people who are disadvantaged in some way, I also put a chapter on disability into the theoretical part, where I gave a definition of disability, its types and forms or for example specific needs that result from such disability. In the second, practical part, the qualitative research method was applied. Data collection was conducted by questioning using the technique of a semi-controlled interview. Interviews were conducted with six communication partners that I have selected using the "snowball" method, so called accretion. The aim of this thesis was mainly to determine how or what for the attendance allowance is used by ist beneficiaries. Whether the amount of the attendance allowance is sufficient for its users to cover the costs of providing the social service. Whether users because of the low value of the attendance will be required to limit their individual needs and interests in some way. Whether users have identified some changes after the amendment of the Social Services Act. For the above objectives I tried to get the answers needed to solve the respective issue.

Infection risks of nursers at the inpatient wards
KUČÍRKOVÁ, Alena
Theoretical backround Working as a nurse is one the most human jobs, by serving to people, taking care and preserve health of a human, which is considered to be the highest value of human life for centuries. The aim of nurses is to take care of a human, to mitigate his or her symptoms and to comfort the life till its end if there is no possibility for full recovery. While they do previously described most of them are not aware of a need to take into account also their own health and especially protection against all dangerous microbes. In my bachelor thesis I analyse infection diseases sometimes also called occupational infections which are the most dangerous for nurses. All occupational infections are stated here together with their descriptions. In following parts of this thesis there are hygiene requirements on the workspace and finally in the last section hygienic-epidemic actions in a health care system are described. Objectives of this thesis Objective 1 Determine whether nurses comply with preventive actions against risks of infections. Objective 2 Determine whether nurses know risks of infections at patients departments. Objective 3 Determine whether nurses know how to defend their spread. Research questions Research Question 1: How do nurses protect themselves against risks of infections? Research Question 2: What information do nurses have about risks of infections in health care system? Research Question 3: In which way do nurses prevent the spread of infection to a de- partment? Methodology The bachelor thesis presents a qualitative research. Methods and techniques of a data collection, which we used in the work were participant observation and semi-structured interviews. The survey was carried out with 6 respondents in anesthesiology and resuscitation departments, surgical and internal intensive care units and intermediate care unit at Nemocnice České Budějvice a.s. The research method of an active observation was used during the survey. We observed certain facts that were recorded during the observation to a observation sheet (Appendix 4) and then transcribed and analysed. Data were collected using semi-structured interviews. The interview was conducted with the same respondents who were observed and recorded in a written form and then overwritten (Appendix 6). Results The results of the observations in the research study showed that nurses unfortunately do not comply with barrier nursing techniques as much as they should. The only thing that they fully comply with the overall finish, wear prescribed clothing and collection of biological material according to hygienic principles. Worse situation was in the using of protective equipment, disinfection and hand washing and eating food, where it did not comply 100%. In the next part of the research we focused on interviews with the observed respondents, the purpose was to find things that could not be identified by the only observing. The results showed that nurses do not even have much theoretical knowledge as regards to a occupational infection, or an injury treatment procedure when infected by an object. Conclusion The survey showed that while most nurses have a clue about good practices and knowledge of the occupational infections and hygienic-epidemiological measures ,but unfortunately theory is different from practice in which these things too oblivious. It emerged that unfortunately practice is different than the theory that we learn at universities and colleges.

Methods of Automated Model Transformations in Information System Analysis
Tůma, Jakub ; Merunka, Vojtěch (advisor) ; Toman, Prokop (referee)
This doctoral dissertation thesis has impact to holistically development extension of information systems. Thesis has impact to analytical models and its transformation methods.
This thesis is focused on models Business Process Modeling Notation (BPMN) and Business Object Relational Modeling (BORM). Model BPMN is developed since 2000. Model BORM is developed since 1993 and it is older. The thesis general target was extension of holistically development of information systems. The main target was to bridge the gap between BPMN and BORM models.
This thesis was inspired by Finite State Machine (FSM). The state of the art describes approaches to models transformation. In the analytical part the mathematical formula are used to describe transformation. This part is used to base for the implementation part. The implementation part contains transformation algorithm its description and verification on the case studies. Impact of developed transformation method is validated on the comparison with the other approaches.
The targets were aimed and documented automated transformation calculus. The impact of automated BPMN and BORM models connection using transformation method. The result is method of automated transformation from BPMN model to BORM model using algorithm. The transformation method is based on the Mealy automaton.

Non-invasive methods for sex and steroid homones determination in gibbons of the genus Nomascus
Bolechová, Petra ; Bartoš, Luděk (advisor) ; Pavel, Pavel (referee)
The gibbon primates of the family Nomascus are classified as critically endangered species, and, to date, basic understanding and information about their biology is missing. With regard to the status of these animals in the wild and captive populations in zoos, being familiar with their reproduction, may improve captive breeding programs. Data collection in this study was to be carried out by the practical use of non-invasive methods (polymerase chain reaction for DNA extraction and enzyme immunoassays), using faecal samples for analysis. The first method, polymerase chain reaction, was used for sex determination in juveniles, because of their coat colour and visual similarity of secondary sex characteristic in both sexes; it is not possible to determinate sex without handling the animal. Another main purpose of this study is to try and answer the hypothesis regarding the ovarian cycle of females, factors influencing their hormone concentration and also the onset of sexual maturity in females and the timing of their fur colour change. Hypotheses were checked by monitoring the concentration of progesterone and oestrogen faecal metabolites and by evaluation of the composition of breeding groups of gibbons with the ZOO influence. During a four year period (from 2010 till 2014), there were a total of 51 animals analysed from 16 different zoos with a faecal sample count totalling 1618 samples. The results confirmed the use of noninvasive methods for sex determination, and thus ensuring the maximum welfare standards. Endocrinological analysis confirmed the hypothesis of the influence of the environment (ZOO) to the hormone concentrations and female´s pregnancy effect in conjunction with her age on the final results of the male - father hormone concentrations. The initial information in this study is the confirmation of the onset of ovarian cycle in young females without connection to their fur colour change and a significant factor of a mother´s impact and her territoriality. This study is the first to present a long term monitoring of ovarian cycles in females and hormone concentrations of other individuals, both male and female, and from various age groups. The results allow us to understand the possible impact of zoo environments on the reproductive status of these gibbons and contribute to the general improvement of breeding management.

Employment in a state-funded institution
Brožová, Milena ; Světlíková, Daniela (advisor) ; Pikola, Pavel (referee)
This bachelor thesis is focused on employment in a state-funded institution. It is divided into a theoretical and an empirical part.
The theoretical part deals with analysis of legal regulations and their interpretation. The method of description is used in this part. The focus in legal regulations is on the problems of a state-funded institution, namely on the legal position and functioning and on management. The focus is also on labour relations, from the general definition to the conclusion of employment for a fixed period of time. The analysis of legal regulations is complemented with interpretations of authors of specialized publications.
Direct and indirect quotations are used in the text and are marked with footnotes.
The empirical part of this thesis deals with the application of legal regulations in a particular state-funded institution. The order of researched areas is in accordance with the theoretical part. The method of comparison and study of documents and internal regulations are used for analysing the data.
The primary research has shown that the legal regulations are applied without difficulty. The discovered discrepancy between the used terminology and the terminology in the Civil code does not invalidate legal documents and thus there is no need to mark it as a defect which needs to be fixed. Suggestions for discussion have been made, for which measures were proposed in the concluding part. The suggestions relate to arrangement of employment for a fixed period of time and its change to permanent contract and to allowance from the founder as a financial mean of a state-funded institution.
