The thesis follows the bachelor thesis on comparison of morphological and economic parameters of various types of seedlings, which resulted in the planting of containerized and bare root seedlings of the European beech (Fagus sylvativa Linne) and the English oak (Quercus robur Linnaeus) in a forest regeneration in September 2011 and April 2012. The measurement of the height and thickness of the root neck of the seedlings was carried out on designated plots in March 2015. I also investigated possible mortality from the afforestation inspection in July 2012. Furthermore, 154 seedlings, 84 containerized seedlings a 70 bare root seedlings, in order to evalutate the development of the root system, its possible deformation and subsequently detection of the volume by using xylometric method. The data collected in the field were processed into tables and compared with the results observed in the bachelor thesis. The average figures for the height, the thickness of the root neck and the volume of the root system showed almost identical development of bare root and containerized seedlings in the forest cover, even though the figures of individual seedlings were highly variable. When reviewing the development of the root system, I found unacceptable deformation of the main taproot at 25% containerized seedlings and 20% bare root seedlings. The remaining seedlings were without deformation or with acceptable deformation of the taproot (wavy taproot, unbalanced taproot with the axis in the above-ground part, an outgrowth). It was discovered that containerized seedlings were more easily removable from the ground, the seedlings were not sufficiently fixed in the ground and its root system was in some cases less developed than it was with bare root seedlings. This may be influenced by several factors, e.g. the influence of richness of the root system on fine roots, the obstruction of development of the root system by cementing the surrounding soil when using the slit method. The bare root seedlings, the English oak in particular, showed root development to a greater depth, which is very important not only for sealing but also as an important factor in the drought season and extreme summer temperatures when there is rapid exhaustion of the moisture in the upper horizon of the soil due to the vapor. Unfortunately, it was not possible to verify these findings in a larger sample size, as there had been major damage of the forest.

The objective of this work is the creation of the design construction, your construction, the influence in the use but also the subsequent demolition at the end of the life of the building any way, or just at least hit the environment. In the first stage it is necessary to think about the necessity to reduce the volume of construction waste in the actual construction of the object. In the second place, it is necessary to solve the ecological aspect of construction throughout the life time construction, whether in the form of waste, and in the form of needed energy. Another essential part is the resolution of the material use in the construction due to construction waste during the demolition. Ideally used as many natural materials that are environmentally safe, easily degradable materials, and in most cases, renewable sources. However, the resulting construction project must meet all the trends of modern living and be a full-fledged construction of the 21. century, which, both in appearance and character fits into the current landscape. In conclusion, this work should be project, when, whose material composition will contain in the highest degree natural materials, especially wood, in which the use of these materials does not affect the quality of construction in terms of physical and mechanical properties and aesthetics of the building. While the actual construction and the technological process should be the shortest and easiest to.

MUDr. BOLDAJI, Abdollah The author in his PhD thesis deals with the assessment of long-term stability of commonly used bevel crown. The work deals with the changes in color, shape, surface integrity, marginal adaptation and the state of the surrounding tissues to determine the ideal facet material.
