Storage Mediums within the Times
Berecz, Tomáš ; Drahanský, Martin (referee) ; Křena, Bohuslav (advisor)
This paper discusses portable storage mediums. In the begining a set of characteristics is presented, by which the storage mediums are rated, along with a division of basic types of stored information. After the definition of the characteristics a chronological overview of the storage mediums is disclosed, with a detailed description. To sum up the paper, a group of tables may be found in the end, in which the mediums are sorted acording to different characteristics.

Poly-para-xylylene films preparation and characterization of their properties
Menčík, Přemysl ; Salyk, Ota (referee) ; Přikryl, Radek (advisor)
Poly-p-xylylene is a basic polymer of parylene family. It was discovered in 50s of the 20th century. In practical applications, there are used several derivates. Most of them are discussed in this thesis. Poly-p-xylylene has many utility properties, like barrier, thermal and mechanical properties. It can be used for conservation and protection of electronic equipments, medical tools and devices or museum exhibits. The most important property of parylene is its low dielectric constant which enables parylene to have good insulating properties in form of very thin layer. The most common precursor used for parylene coatings by Chemical Vapor Deposition (CVD) is [2,2]paracyclophane. Special device invented for this process was described in this thesis, including every part and assembly. The main aim of this thesis was to test properties of thin parylene layers on metal samples. High degree of polymer crystallinity was confirmed by confocal laser microscopy and optical microscopy in the polarized light measurements. Problems in the conventional method of production of parylene layers were found during the measurement of thickness of layers. Purity of deposited films was determined using Infrared spectroscopy (IR). Parylene barrier properties were quantified by the measurement of Oxygen Transmission Rate through a layer deposited on the surface of PP foil. Because the research has been mainly focused on protection of museum exhibits, the corrosion resistance test is the most important. Metal samples with thin parylene film were compared to samples with conventional restoration coating. The samples with parylene protection were slowly corroded by point corrosion. In contrast to them, the samples conserved by conventional restoration method were almost destroyed by corrosion.

Reconstruction of Data from Damaged CD/DVD
Jarolím, Jordán ; Zbořil, František (referee) ; Drahanský, Martin (advisor)
This bachelor thesis deals with the reconstruction of data from a damaged CD/DVD. The aim is to create an application which will be able to get a bitstream from an image (scanned fragments of a disc) acquired by an optical or electron microscope. This thesis also examines a data representation on the disc, process of preparation of specimens of CD and DVD and scanning of these specimens. The algorithm of the created software, its testing and results are described in this thesis as well.

Home Multimedia Centre
Burkert, Michal ; Herout, Adam (referee) ; Sumec, Stanislav (advisor)
This thesis deals with design and implementation application, that should be equivalent to several eletronic devices such as DVD player or videotape recorder. Computer used for this purpose is often branded as Home Theater Personal Computer (HTPC). This thesis studies available multimedia libraries and software in operating system Linux, that is used to create designed application. It shows some similar existing application to create HTPC either commercial or opensource.

Dětští mediální hrdinové
MADAROVÁ, Tereza
This bachelor thesis focuses on children's media heroes. Semi-structured interviews with selected children from ages six to twelve from elementary school in Kardašova Řečice were used for the research. Twenty one children participated in the research were answering questions about favorite heroes, watching TV, reading books or playing computer games. The primary purpose of this thesis was to determine what media heroes children choose, for what reason and where the heroes come from. The secondary purpose are the topics arising from the interviews with children, media consumption by children in general, its possible risk, pertinent regulation by parents and so on.

Creating an instructional DVD of Nordic Walking and compensation exercises for seniors
VEITHOVÁ, Monika
The aim of this study was to design and verify 5 month long Nordic Walking exercise program for seniors. The participants learnt proper techniques and gained physical power, after undergo the program. The theoretical part of this study discusses history of Nordic Walking, appropriate equipment and general characteristics of Nordic Walking including applicable walking techniques, overall influence on health and main principles of compensatory exercises. The methodology contains an instructional DVD. The Kasch step-test was used to evaluate physical mobility, physical power and muscle gain, according to Janda's hypermobility test. The results enhance common knowledge about Nordic Walking and put some improvement in practise.

Šatra, Michal ; Chrzanowská, Babeta (advisor) ; Čechovská, Irena (referee)
Bibliographic identification ŠATRA, Michal: The historical development of the technique of swimming styles in connection with changes in the rules [Diploma thesis]. Charles University in Prague. Faculty of Physical Education and Sport. Department of Swimming. Supervisor: Mgr. Babeta Chrzanowská. Prague: FTVS UK, 2012. Abstract The aim of this thesis is to describe the development of the techniques of each individual swimming style on the basis of all available materials and to discover its connection with significant changes in the respective style's rules. The purpose of this thesis is to point out the most important changes in the rules of swimming within their historical context. A DVD which contains a practical demonstration of various swimming styles forms part of this work. Keywords Swimming, free style, breaststroke, backstroke, butterfly, swimming style, swimming technique, historical development, contemporary style, rules, historical photos, DVD.
