The purpose of this thesis is to analyse and evaluate time management of managers of small businesses and to propose optimal use of their time. Specifically, the thesis focuses on time management of managers of small businesses in the sector of communications and information services. The first part of the thesis focuses on theoretical description of 10 techniques, which are considered to be helpful in pursuing more effective time management. The next part of the thesis is practical and it is focused on the aim of the thesis. Two methods of analysis were used for this purpose. Firstly, it was questionnaire survey focused on analysis of basic characteristics of selected file's time management. Based on that, I was able to prepare an approximate proposal for making time management of this sample more effective. In order to develop a recommendation that will be tested in practice, the effectiveness of this proposal was examined through a second research method and thus in-depth interviews. Two detailed individual interviews with each respondent were carried out. In the first one, the specific situation of each of the respondents was analysed and the universal plan was adapted according to their individual needs and proposed to them. Managers followed the plan for few weeks and then gave me feedback on its effectiveness through a second in-depth interview. The final recommendation is divided into 2 sub-sections. All steps in the plan are covered in detail. The proposal contains visual example of righty scheduled day.

Les services de téléphonie IP automatisent le traitement des stimuli de communication en utilisant des ressources réseaux. Cependant, l'ajout de services rend vulnérable le système de téléphonie car certaines propriétés de fonctionnement des services déployés ne sont pas garanties. Aucune solution de développement de services ne permet de simultanément garantir des propriétés de fonctionnement et d'exploiter des ressources réseaux. Cette thèse propose une approche fondée sur le concept des langages dédiés pour développer des services de communications. Deux nouveaux langages dédiés au domaine des communications ont été développés : SPL et Pantaxou. Le premier sert à router des messages de signalisation tandis que le second, plus généraliste, permet la coordination d'entités communicantes. Dans cette thèse, nous démontrons, grâce à SPL et Pantaxou, que les services de communications peuvent être développés avec un langage de programmation expressif tout en préservant des propriétés critiques du domaine. / IP telephony services use network resources to automate communication stimuli processing. However, deploying services on a telephony system leads to safety issues and programmers need to ensure some safety properties on their services. Several approaches allowing service development have quickly emerged. However, none of them is both expressive and safe. This thesis proposes a new approach that relies on domain-specific languages (DSL) to develop communication services. Two new DSLs have been designed for communication services, namely SPL (Session Processing Language) and Pantaxou. The first one allows to route signaling messages while the second one, more generalist, enables to define coordination logics of communicating entities. In this thesis, we demonstrate thanks to SPL and Pantaxou that communication services could be developed with an expressive programming language that preserves some critical domain properties.

This International Workshop is a high quality seminar providing a forum for the exchange of scientific achievements between research communities of different universities and research institutes in the area of innovation information technologies. It is a continuation of the Russian-German Workshops that have been organized by the universities in Dresden, Karlsruhe and Ufa before. The workshop was arranged in 9 sessions covering the major topics: Modern Trends in Information Technology, Knowledge Based Systems and Semantic Modelling, Software Technology and High Performance Computing, Geo-Information Systems and Virtual Reality, System and Process Engineering, Process Control and Management and Corporate Information Systems.
