The effect of selected parameters of stream water on gill morphology of brook charr and the structure of ichthyofauna of the Jizera Mountains
Hušek, Jiří ; Švátora, Miroslav (advisor) ; Dušek, Martin (referee)
The occurrence of ichthyofauna on the territory of the Jizera Mountains (Northern Bohemia, Czech Republic) is limited, besides other factors, by the water chemistry. pH value and pH-related concentration of inorganic monomeric aluminum (Ali) are crucial parameters of the water, determining the survival of fish in streams. Low pH and high concentrations of Ali cause severe damages to fish gills. The thesis deals with the influence of the water chemistry on distribution of ichthyofauna in the Jizera Mts and gill morphology in brook charr (Salvelinus fontinalis), a dominant fish species of the upper plateau of the mountains. The results show that the species diversity of fish in acidified streams is lower than that in streams without meaningful acidic episodes. Histopathological analyses of gills of brook charr individuals from an acidified stream confirm, that low pH values and high concentrations of Ali have a cummulative effect and lead to degenerative changes on gills. Key words: The Jizera Mountains, ichthyofauna, brook charr, gill morphology, water chemistry, toxic aluminium, acidification

Geocaching in relation to sustainable development
Dolejšková, Adéla ; Rynda, Ivan (advisor) ; Hušek, Jiří (referee)
This thesis is focused on relation between geocaching and sustainable development. It deals with this relation on basis of approach of geocachers to cache-making and on basis of state of caches in different areas. Approach of geocachers to cache-making tests by semi-structured interviews analyzed by Grounded theory and by internet data analysis. State of caches in different areas tests map data analysis. Outcome shows rather positive relation of geocaching and sustainable development. Strong points of the game are in positive influence on sustaining and shift of memory of places, increasing place atractivity and partly environmetal education. Study can be beneficial for instance for protected natural areas administration, public administration or administration of destination management of areas. Scientific benefit of this thesis lies in surveying this theme and creating basis for next research. Keywords: geocaching, sustainable development, sustainable tourism, destination management, environmental education. Powered by TCPDF (www.tcpdf.org)

Description of the Industry 4.0 concept, current application and market status
Hušek, Jiří ; Pour, Jan (advisor) ; Příklenk, Lukáš (referee)
This master thesis maps contemporary situation linked to the Industry 4.0 topic and sets it into connections and define its relations. The first part is dedicated to describing the beginning and nature of Industry 4.0. Next part shows main national initiatives of several countries. In the other part of thesis there is specific description of terms connected to this concept. Next part is about evaluating benefits, risks and restrictions. After that there is description of present use on market. The last part sums some predictions about Industry 4.0.

Analysis and solution design of document management
Hušek, Jiří ; Pour, Jan (advisor) ; Kohlerova, Zuzana (referee)
The main subject of the thesis is to analyze the current state of flux documentation in the Czech branch of the large company engaged in the production of rail vehicles. Included is also a newly proposed solution, which should reduce costs and save time of workers in the company. The main goal is to design a solution that will reduce the running costs compared to the current flux of documents. It should be economical, meet all the requirements of the organization and similarly challenging, both hardware and servicing. The thesis describes the current system of documentation that is associated with production processes in the company. It also defines the most important group of documents that are intended for the production and processes of each department. Based on this analysis, it is suggested a comprehensive ERP system for administration and control of production, which is connected with the Document Management System (DMS) based on workflow, as well as a system of Product Lifecycle Management (PLM). Augmentation of equipment of the controllers with tablets and hiring printing administrator is also suggested. The thesis is divided into five main chapters. The first chapter provides the basic theoretical concepts that are associated with problems of document management. The second chapter describes the analyzed company, the actual document types and environments in which they occur and documents are created in it. The third chapter analyzes the actual process of flux of documents of each department relating to the production itself. The fourth chapter describes the current state with its shortcomings, and in the fifth chapter a proposed solution is described.
