The aim of this thesis is to create a comprehensive view on questions of development and influence of media on society and related formation and processing of information. This thesis should also enable the reader easier understanding and orientation in this topic. For that reason the thesis is divided into four main parts. The first section describes what is information, and the relation among data, information and knowledge. The second part is devoted to development and influence of information and communication technologies. It describes ways which enabled and enable to deliver information to its recipient and also related changes brought by these technologies. In the next chapter there is desribed what influences our relations within the framework of single nations and how media help to their convergency and linking. And the last part of this thesis includes an analysis of possible use and misuse when affecting broad masses of people.

This thesis focuses on possibility of chaotic (specially economic) time-series prediction. Chaotic time-series are unpredictable in long-term due to their high sensitivity on initial conditions. Nevertheless, their behavior should be more or less predictable in short-term. Goal of this thesis is to show, how much and if any prediction, is possible by non-linear prediction method, and try to reveal or to reject presence of chaotic behavior in them. Work is split into three chapters. Chapter One briefly introduces chosen important concepts and methods from this area. In addition, to describe some prediction methods, there are outlined which indicators and methods are possible to use in order to find possibilities and boundaries of this prediction. Chapter Two is focused on modifications of FracLab software, which is used for create this prediction. Last chapter is experimental. Besides the description of examined time-series and methods, it includes discussion of results.

Graphic figures and various types of infographics have become an essential part of the scientific papers, business presentations and study materials. Although, authors of these documents often lack the knowledge of basic rules and principles of graphic design and learn how to create figures by trial and error. Literature addressing the issues of effective verbal (presentation skills) and non-verbal (principles of scientific writing) is available and accessible. Though literature addressing the issues of scientific figure design and general visual design are very few, sometimes non existent, despite the fact that images, figures and various charts are one of the most effective mediums for information sharing. This lack of material knowledge is detrimental to the quality of works of managers, professors and researchers. This thesis attempts to fill in this gap and motivate readers to further development and research of the issue. The thesis addresses the issue of figures from its core, those being the basic principles of image perception and interpretation. Building on concepts of theorists like Peirce, Saussure and Eco the thesis will then define the meaning and purpose of "Image Interpretation Value". Selected principles of figure construction and interpretation will be introduced. These principles will then be further analyzed and applied on the level of business and scientific figures. Each chapter will include various graphic figures and practical examples to enhance further understanding of the issue. The primary purpose and goal of this thesis is to create an easy-to-follow set of instructions and suggestions on how to design effective and intelligible figures to be used in the fields of business communication, scientific research and academic teaching.

The current legislation that regulates internal managing and controlling system in administrative bodies of the public governance lags behind in the implementation of international experiences and standards for excersing the internal audits. This fact causes many reactions in the general public and also in the professional society. Alarming news about corruption and wasteful use of the public sources are just the token of the problem. The goal of this thesis is to define and analyze the process of implementing the managing and controlling system and subsequently to create a plan for a successful implementation of the effective managing and controlling system in the public governance. In the theoretical part are characteristics and goals of the managing and controlling system, legislative framework and description of components for the managing and controlling system, that are based on international experiences and practice. In the analytical part is the analyze of the particular elements from the managing and controlling system and finally in the practical part is the proposal of implementation managing and controlling system and also the proposal of directive for the internal control, which is supposed to simplify the practical use in the public governance. There is a draft of the assessment of Internal Control System Effectiveness in the practical part of this thesis.

This paper contributes to the literature by presenting a detailed summary of existing problems with credit rating agencies and proposing a model of a European Rating Agency that acts as a competitor and benchmark to the established credit rating agencies. European Rating Agency (ERA) as a new entrant will make a difference by increasing rating transparency and reputation cost for rating agencies at the same time. A vital point when developing the idea of an independent rating agency was the minimization of regulation changes. This will help shareholder to better orientate and understand the functionalities of the European Rating Agency which will make its establishment process easier. Reputation cost (capital) are assumed to be the building blocks that support the unique position of current rating agencies. ERA is modelled specifically to target this information and use the fragile concept of trust and reputation to the benefit of all stakeholder.

The theme of this diploma thesis is Knowledge Management that is becoming the focus of business companies. The theoretical part of the work is divided into several chapters that discuss the basic principles of Knowledge Management. The aim of this work is to describe the principle of knowledge management and create a basic draft of the knowledge base for the KPMG company. In the introductory part of the work, terms commonly used in knowledge management are explained. Further, the knowledge capital of the company, types of knowledge management and the related knowledge strategies are described. Second half of the theoretical part concerns the responsibilities, tasks and roles in knowledge management. The last chapters of the theoretical part describe the individual phases of knowledge management introduction in a company. The practical part of this thesis is focused at analysis of KPMG company knowledge management and design of a knowledge base that can substantially reduce the time necessary for completion of certain deliverables. The chapter concerns mainly with description of the system architecture of the knowledge base, that the author has designed for the KPMG company.

The thesis defines the basic concepts of data, information and knowledge for which monitors the mutual ties. It uses them to define the dynamic process of knowledge that will further clarify the use of cognitive aspects of work with knowledge of the individual, group or organization. It follows the knowledge management processes that attach to the creation and knowledge transfer opportunities. An important part of this work is to assess the role of knowledge in information systems. In particular, it deals with the role tacit knowledge in decision support systems. For each types of systems observes their ability to work with knowledge and information, the suitability of the type of solved problems and their flexibility. Finally, considering the possibilities of further developments in relation to solving complex dynamic problems.

Diploma thesis focuses on clarifying of sociocybernetics principles and its connection to other sciences. It refers to possible approach to information, knowledge, systems. Further, it appeals to individuals in terms of social system and their values, abstract reality perception, utilization of feedback, autopoiesis (self-organization) and many others. Theoretical frame offers to reader awareness about this topic. Practical part points out possible application of this concept along complex organization analysis. Results of analysis refer to bottlenecks and possible improvements, in terms of sociocybernetics principles and methods.

This thesis compares the environmental information systems and the providing of environmental information from the government institutions. The objective of this work is to analyze current information systems under the Integrated environmental information system (JISZP) and verify the hypothesis that all these information systems are integrated. The further goal is to prove whether or not the Act No. 123/1998 is fulfilled in practice. The first part contains an analysis of JISZP systems according to various criteria.

At the present time, characterised by increasing complexity of not just socio-economics systems, decision-making in positions of executive management is becoming increasingly difficult. Although more and more attention is dedicated to use of information and communication technologies in corporate sector and organizations collect unprecedented amount of very detailed data from all areas, their real nature is often not considered. Data, information and knowledge, through which we can achieve real understanding of causes of the observed systems behaviour, are necessary basis for ability for prediction of tomorrow's effects of today's decisions. This thesis aims to highlight the essence of data, information and knowledge in organization and the necessity of systemic perception for creating efficient and effective decisions. The second part of this thesis presents design of system-dynamic model (including user interface), which explains the mechanisms of health care volume accounting in medical facilities with more departments. The model should facilitate understanding of functioning of hospitals by the public, and respect of general nature of medical facilities functioning to create a base for robust model-oriented decision support system for the management.
