New version of the Diffie-Hellman problem
Sayedová, Monika ; Holub, Štěpán (advisor) ; Hojsík, Michal (referee)
The Diffie-Hellman (DH) problem is a problem that is assumed to be difficult to do, hence the security of many cryptographic protocols is reduced to this problem. We show a new variant of the DH problem - the twin DH problem. We propose a method which allows us to simulate a decision oracle without knowing the discrete logarithms of the elements. We show twin ElGamal encryption and its security in a random oracle model. ElGamal is secure against chosen ciphertext attack when we assume that the symmetric encryption is secure against chosen ciphertext attack and the DH problem is hard. We prove that the DH non-interactive key exchange protocol is secure against an active attack in a random oracle model when the DH problem holds. 1

Need of a resuscitation standard in inpatient medical facilities
DLOUHÁ, Hana
The diploma paper presents a brief overview of the development of resuscitation in the world and current recommendations for resuscitation by the European Resuscitation Council. Also included is a description of basic diagnosis of a sudden cardiac arrest, providing vital functions, including the use of alternative materials and the problems of resuscitation in hospitals. Providing effective resuscitation is reflected in the quality of care provided, which is much emphasized nowadays, especially for the accreditation of medical facilities and the creation of standards for nursing care. The objective of this paper is to determine and compare the extent of knowledge of nurses in the inpatient departments of emergency cardiopulmonary resuscitation at two hospitals, one of which uses a standard resuscitation. Another objective is to create a resuscitation standard for nurses at inpatient departments, submit it to involved nurses for assessment and to determine to what extent the created resuscitation standard contributes to the work of nurses who have not used it yet. The first research question is: How do nurses view the newly created standard? The second research question is: Will nurses appreciate the contribution of the created standard? A given hypothesis implies a greater knowledge of nurses who use the resuscitation standard, than nurses who do not use it. The first phase used a quantitative survey using the questionnaire technique; skills and knowledge of nurses were mapped at two medical facilities, one of which uses a resuscitation standard valid for the entire facility. The questionnaire included 34 items, 21 questions dealt with the knowledge of nurses surveyed, and 13 questions mapped demographic data, work organization and the respondents{\crq} workplace experiences with resuscitation. Based on the results of the quantitative survey, the hypothesis has been confirmed. The results also unveil weaknesses in the training of medical personnel at both hospitals and the surveyed nurses{\crq} knowledge. In the second phase of the survey, nurses who did not have a resuscitation standard were presented with the resuscitation standard version for assessment. The assessment of the standard was carried out with qualitative survey using semi-standardized interviews with senior nurses at nursing stations. These nurses assessed the presented resuscitation standard positively; they welcome its presence and see its benefits in improving nursing care.

The Novel Fortress Besieged: A Translator's Challenge
Lexa, Filip ; Andrš, Dušan (advisor) ; Zádrapa, Lukáš (referee)
Qian Zhongshu's novel Fortress Besieged (Wei cheng), employing a wide variety of literary devices and abounding in cultural references, is a piece of literature exceptionally difficult to translate. This thesis identifies the main categories of problems the translator will encounter during its translation. Taking the English, French and Spanish versions of the novel as its ground, the thesis investigates what the paths are that the translator chooses when translating literary works culturally remote from the target language reader. The author starts out with the theories of Jiří Levý and approaches translation problems from a functional standpoint. He finds out, however, that a successful translation requires an effort not only from the translator but equally from the reader.

Web services support in the .NET framework
Fischer, Roman ; Buchalcevová, Alena (advisor) ; Máša, Michal (referee)
The work targets the very important part of service oriented architecture -- web services. It is focused at one of its practical implementation, from the Microsoft Corporation, especially in the last two releases of .NET Framework. The main target of this work is comprehensive summary and demonstration of Microsoft web services development. The principles of web services and their base in the .NET Framework are described here. At the beginning of this work the web services are put into the scope of service oriented architecture and their main principles are described. Subsequently the .NET Framework is explained with its main principles and with the comparison to the JAVA technology. This part is finished with the explanation of classic ASMX web services. The main part of this work focuses at detailed description of the theoretical and practical aspects of web services in the Windows Communication Foundation and the Windows Workflow Foundation context. Even the development of Windows Forms application is not left out, because they also have done a large progress and they are often consumers of web services. The options of securing web services in the .NET Framework are shown both theoretically and practically including authentication and authorization. The methods of transactional behavior are shown too. The work also focuses at the orchestration of web services including the explanation of workflows with the deployment example. At the end of the work there is revealed how to guarantee interoperability with other technologies, how to manage web services and how to ensure their versioning.

Passive forms in Italian and Czech from the perspective of functional styles
Čechová, Petra ; Obstová, Zora (advisor) ; Štichauer, Pavel (referee)
The aim of this thesis is to theoretically describe periphrastic and reflexive passive in both Italian and Czech language, to establish approximate frequency of Italian periphrastic passive in different functional styles with the help of parallel corpus InterCorp (version 8) and to analyse the means of its translation into Czech. The initial theoretical part deals with a brief description of grammatical categories of verbs, then it focuses on grammatical voice and diathesis and it discuss further the differences in the notion of these terms. Subsequent chapters deal with formal aspects of the passive in both Italian and Czech, with its function and with the restrictions of its use. The last chapter describes the use of the passive in functional styles. The following practical part describes in brief InterCorp and subsequently deals with the problem of analysing the approximate frequency of periphrastic passive in the belles-lettres, newspapers and official type of texts. Finally, it analyses 200 instances of the periphrastic passive in each of the previously mentioned functional styles and it focuses on the means of its translation into Czech.

Selecting an optimal set of features for the morphological tagging of Czech
Raab, Jan
This work continues in implementational and experimental project Morče, which aimed to create the best possible morphological Czech tagger based on hidden Markov model with averaged perceptron. Successfulness of algorithm depends mainly on a selected set of features describing a context, which determines choice of a tag. The work describes briefly the algorithm and its implementation. Main part of the work consists of a lot of experiments which explore possible feature sets, their successfulness and their relationships. Few clear rules are defined for comparison of versions. Fivefold crossvalidation with t-test is used for verification of statistical significance. After the work was started, new Czech data became available, so all experiments used data from PDT 2.0. Side effect of this work was statistical significant improvement of successfulness. However, the best Czech tagger was obviously not overwhelmed. Some modifications were made in order to perform automatic version development. It was executed in small extent and also described.
