The work deals with the topic of electronic communication with the tax authorities. The theoretical part starts with the research of related work and then the development of e-Government to nowadays form is presented. The legislation regarding electronic communication with tax authorities with possible changes towards future follows. The theoretical part of the work is finished with statistics regarding electronic communication with the tax authorities and with comparison of the situation in the Czech Republic with the situation in other European Union countries. In the practical part of the work, a set of best practices which should be obeyed by tax advisors is presented as a main output of the work. Practical part also contains a survey and statistical analysis of data arising from it. The survey is unique because of the fact that all respondents are tax advisors. In the last part, based on the survey, the benefits and shortcomings of the electronic communications with the tax authorities as well as possible steps to streamline are presented.

This thesis work is to do with the Information system of data boxes (ISDS) which is introduced from legislation's and user's point of view. Because the introduction of this system has influenced hundreds of thousands of subjects the main target of this thesis is to find out about the impact of the ISDS on users with the help of the analysis method. In this work firstly the data provided by the Ministry of Internal Affairs are examined and interpreted, secondly the results of the poll conducted by the author and then a cost-benefit analysis of the system from the users' point of view is carried out. The results of the work show that the ISDS was at the end of the examined period (2009 -- 2013) beneficial for its users and the total economic benefit for the respective period is 3.6 billion Czech crowns. This means that every crown spent on the operation of the system by the Ministry of Internal Affairs represents savings of 2 Czech crowns. The author of this work has come to the conclusion that the system is from a legislative, technological and economic point of view very well created. The author recommends to the system administrator its further development and also recommends to use its potential among thousands of OSVČ (the self-employed).

Master´s thesis analyses modern methods of communication in company management. The objective is to discover out the crucial defects of this issue and to outline possible solutions which would improve the weaknesses – of internal communication. The master´s thesis consists of three parts: The theoretical part is concerned about communicational instruments which have been used by the operational company ČEPRO, a.s. The analytical part describes implementation of communicational instruments in the company. (external communication, internal communication, crisis communication and communication during the new product implementation) The proposal part recommends appropriate elements for efficient communication within the current communication system in the company.

The master’s thesis concerns about analyses of existing conditions of Stim tools, PLC., its surroundings and factors influencing its customers. The thesis is based on theoretical knowledge of marketing, which is used for the company description in the practical part of the work. Based on the existing information a proposal of communication strategy for this company is suggested.

Die vorliegende Dissertation beschäftigt sich mit dem elektrochemischen Verhalten verschiedener Ferrocenyl-substituierter Thiophene. Dabei wird sich zunächst mit dem elektrochemischen Verhalten der Serie der Ferrocenylthiophene beschäftigt, die Anzahl der Ferrocenyleinheiten variiert von n = 1 – 4. Die Abhängigkeit der elektronischen Eigenschaften von numerischen und konstitutionellen Veränderungen der redox-aktiven Gruppen wird evaluiert. Daraus resultierend wird sich einer eingehenderen Untersuchung und Modifikation des 2,5-Diferrocenylthiophen-Motivs zugewandt. Diese Modifikationen werden im Kontext möglicher Ladungstransferprozesse zwischen den Ferrocenyleinheiten in den verschiedenen Redoxzuständen und unter Beeinflussung durch den Thiophen-Brückenliganden diskutiert. Es folgen des Weiteren Ausführungen zu Substitutionen an den Ferrocenylen (Einführung elektronen-ziehender Funktionalitäten) sowie der Vergleich zwischen einer Thiophen- und der Ethylendioxythiophen-Brückeneinheit. Anschließend wird sich mit der elektronischen Variation des Brückenliganden durch die Einführung von N-haltigen Substituenten befasst. In den abschließenden Kapiteln wird der Einfluss zusätzlicher σ- (Fischercarben-Komplexe) oder π-gebundener ([Ru(η5-C5H5)]+/[Ru(η5-C5Me5)]+) Übergangsmetallkomplexfragmente auf Ladungstransferwechselwirkungen im 2,5-Diferrocenylthiophen in verschiedenen Redoxzuständen beleuchtet.
