Versatile O/R database manager
Plonka, Jan ; Kopecký, Michal (advisor) ; Říha, Antonín (referee)
The goal of this thesis is to design and implement a tool for the O/R databases administration. It places emphasis on maintainability, univerzality and extensibility of the solution. Without a need of installation, using web browser, it is possible to administrate remote databases from client workstation. The tool is easily extensible to support a new DBMS as well as a new object type within existing DBMS. The tool is intented for interactive schema management.

Reflective simulation of patients-in-bed movement
Gargulák, Jan ; Kindler, Evžen (advisor) ; Říha, Antonín (referee)
The work at first proposes ideas of the nested and external simulation. The external simulation works with the model M and the nested simulation work with the model N. The external simulation always calls nested simulation so that the nested model N is initialized according to the state of the external model M and then the nested experiment is performed. Its result can influence the state of the external model. The reflective simulation is a special case of the nested simulation when the external and the nested models are identical or almost identical. We describe how to implement reflective simulation in Simula language. Using this knowledge, we implement reflective simulation of patients-in-bed movement in Simula language. The resulting fully functional program clearly demonstrates properties of the reflective simulation.

Implementation of Modern Approaches in Electronic Health Record
Dioszegi, Matej ; Nagy, Miroslav (advisor) ; Říha, Antonín (referee)
In the present work we study the possible implementations of electronic health record using modern technologies. The main goal is decomposition of server functionality among multiple parts. We use the idea of web-services, which means that each part of the system offers services available for remote hosts. The components communicate with each other using the SOAP protocol. We also study the possibility of storing patient's administrative information into separate storage, which suits the purpose better than original data trees, which are used to store clicnical information. Besides, this separation is suitable for anonymization of data used by statistical computing. In my work the manner of storing patient's clinical data in data trees and possibility of flexible modeling of data layer using knowledge trees, which together create a knowledge base, is preserved.

Conceptual modeling of neurosurgical data.
Bystroň, Jakub ; Říha, Antonín (advisor) ; Nečaský, Martin (referee)
We present a new minimalistic conceptual model for hierarchical data called AC-model. Syntax part of this model is based upon the regular tree grammar theory. AC-model is composed of two parts - Archetype model and Constraint model. A-model is intended to model arbitrary regular tree grammar, C- model adds a first order logic constraints. We also prove that validity problem for ACmodel is NP-hard and conformance problem is undecidable. Along with this thesis C-model based validator of XML documents' semantics is presented.

Benefits of object-relational technology
Paľo, Martin ; Říha, Antonín (advisor) ; Kopecký, Michal (referee)
Lately, object-relational databases have become increasingly popular. Compared to the traditional approach, they provide many new possibilities. This thesis describes the general requirements on object- relationaJ systems and the new object-relationaJ enhancement of Oracle, as well as similar enhancements of other well-known database systems and their comparison with the SQL: 1999 database standard requirements. An essentia1 part of this thesis is concerned with the comparison of the relational and object-relational in1pJementation of the student information system using the Oracle 9i database server.

Clinical Content Harmonisation of Electronic Health Record
Nagy, Miroslav ; Říha, Antonín (advisor) ; Dostálová, Taťjana (referee) ; Veselý, Arnošt (referee)
Title: Clinical Content Harmonisation of Electronic Health Record Author: Mgr. Miroslav Nagy Department: Department of Medical Informatics, Institute of Computer Science v.v.i., Academy of Sciences of the Czech Republic Supervisor: RNDr. Antonín Říha, CSc. Supervisor's e-mail: riha@euromise.cz This PhD thesis deals with the possibilities of clinical content harmonisation in elec- tronic health records (EHR). In the first sections, the current state of the art in the field of EHR and other related fields is summarised, as well as that of the tools supported by current software technologies and the results of research in the field of medical in- formatics. The work is focused on analysis of obstacles in sharing medical data and on proposals of steps for overcoming these obstacles. Next, the utilized tools, modelling approaches, standards and coding systems used during the research are summed up. In the following sections the methods pointing to achieving harmonized clinical models are elaborated on and resulting clinical concepts mappings, supporting tools, developed EHR systems and semantic interoperability platforms are presented. In the conclusion these results are discussed and some future work is proposed. Keywords: electronic health record, semantic interoperability, clinical content, har-...
