The modification of the product and its impact on financial indicators
Šikyňová, Katarína ; Mlejnková, Lena (advisor) ; Kvítková, Zuzana (referee)
The main purpose of diploma thesis named The modification of the product and its impact on financial indicators is to design products respectively. services worthy modifications to recalculate the costs and returns of this modification, and consequently its total return for recreational and gastronomic company operating in tourism. The theoretical part of this thesis contains definition of fundamental termsand market research through questionnaire survey, which aims to characterize the structure of the company and obtains from its customers their designs products. Afterwards the results of survey will be interpreted. At the end of the thesis, in cooperation with the management of the company, the effects of modifications on financial indicators will be analyzed to define if the modification is the desired effect .Analyze the effects of modifications is the main objectives of this thesis.

Possibilities and importance of physical education of pupils with visual impairment in the basic education.
VRŠNÍKOVÁ, Kateřina
Subject of this bachelor thesis is the opportunity and meaning of physical education for visually impaired pupils at primary school. The main aim is to perform a modification of the education plan for visually impaired pupils. The aim of this bachelor thesis is to present theoretic points of the meaning of physical education for optimization of development of all character attributes of the pupils with visual handicap. The other aim of this bachelor thesis is to modify an education plan in the subject "Man and Health" (Physical Education) for visually impaired pupils at primary school. This bachelor thesis is composed of a theoretical and a practical part. The theoretical part deals with the processing of the starting theoretic points, which topic is visually impaired pupils or children. I dedicate to visual handicap, its definition and classification in the literary research specifically. The theoretical part also presents the specifics of the visually impaired child's development, its motor, mental, cognitive evolution and its progress of exercise and spatial orientation. The other topic of the theoretical part is the early care and education system of visually impaired children. The last biggest chapter of the theoretical part are some chosen physical and sport activities for visually impaired children. e.g. athletics, swimming, cycling, goalball and showdown, suitable for visually impaired children. The practical part deals with a modification of the education plan itself at the primary school at České Budějovice. Firstly, there is introduced the aim of the thesis and research methodics. This is followed by a summary of the results of the quantitative research, modification of the education plan and the conclusion of the thesis. A document analysis and an interview were used as methods of research in this bachelor thesis. The interview was held with teachers from primary school at České Budějovice. On the base of research there was made a modified education plan for physical education. Suggested modifications have material, personnel, didactical and methological character. The base for data processing was research results from analysis and literature and from interview with teachers at the primary school at České Budějovice. This bachelor thesis should serve as a study material for pedagogic students at university, also for public and it should be used by teachers for visually impaired pupils at primary school.

Změna barvy povrchu modifikovaného dubového dřeva působením umělého slunečního záření
Rozboril, Tadeáš
This bachelor thesis conducted as an experiment is concerned by the color change of modified oak wood surface affected by artificial sun light. Part of the thesis is also focused on influence of chosen modification to the color change of oak wood surface. Samples of oak wood for experiment were modified by ammonia and by iron nanoparticles. Both modifications darken the surface of samples. Color change by the artificial sun light was measured on modified oak samples, also on subfossil and natural oak wood. The dry regime caused darkening of untreated oak, and whitening of all other samples. The wet regime caused whitening of all samples, however smallest color change was measured on samples modified by nano-iron.

Možnosti uplatnění modifikovaného dřeva ve stavbách
Peterková, Eva
The bachelor thesis summarizes modified wood and describes its use in buildings. The wood has changed physical and mechanical properties. It closer discusses about thermally modified wood because it is the most widespread in the world and also in Czech Republic. It has lower values of mechanical properties, but the thesis shows the possibility of using wood as a construction material in the areas with higher amount moisture content. Measurement confirms change of mechanical properties, especially bending strength, and the results of measurement compression strength show the possibility of use thermally modified wood in areas exposed to pressure.

Zkoušení pevnosti spoje lamelovaných hranolů pro výrobu oken
Hála, Marek
The first part of the diploma thesis deals with modern glued lamellar prisms for the production of windows, doors and their combination. The procedure of the euro balks production is the essential part of the work. Furthermore, the thesis focuses on the characterization of the wood modification, above all thermally modified wood which is currently used in practice. Moreover, at the present new modified material known as the wood treated by acetylation (Accoya). The practical part deals with the assessment of the bonded lamellar prisms' quality and rigidity. Next examination is devoted to two types of glue (PVAC, PUR).The prisms with two directions of the fibres in the middle layer were tested. The timber from the tangential and semi-radial direction was used for the middle layers. The conclusion if the produced prisms meet the requirements and satisfy the quality class for the window and door production, is included in the discussion.
