Restoration of sgraffito on a cement base
Machačko, Luboš ; Bláha, Jiří
Hlavním záměrem předkládaného památkového postupu bylo popsat specifika sorelového sgrafita, pojmenovat hlavní problémy jeho restaurování a na postupech ověřených zkušebními zásahy navrhnout vhodné řešení. Podkladem stanovení postupu jsou výsledky terénního a laboratorního výzkumu získané v průběhu výzkumného projektu. Úvodní tezí výzkumu, který stanovení památkového postupu předcházel, byl literaturou často opakovaný fakt, že se pro sorelová sgrafita využívala cementové omítky. Objevoval se nejen v recentní literatuře, ale zdůrazňovaly jej i dobové příručky. Při samotném restaurátorském průzkumu a laboratorním vyhodnocení odebraných vzorků byl vyvrácen. Ukázalo se, že sgrafita 50. let byla ve většině případů prováděna tradiční vápennou technologií. Samotné cementové sgrafito se stalo až výsadou 60. a 70. let 20. století a často bylo využíváno v poloprofesionálním či přímo amatérském prostředí. Hlavním rozdílem mezi sorelovými sgrafity a sgrafity předchozích etap vývoje tak byla volba podkladu. Sorelová sgrafita byla často prováděna na cementovém (betonovém) podkladu, resp. na panelech. Ve zkoumaných příkladech nevyplynuly z této skutečnosti závažnější problémy, které by bylo nutné při restaurátorských zásazích aktuálně řešit. Předkládaný památkový postup tak především definuje ostatní problémy, s nimiž se restaurátoři setkali, a popisuje metody restaurování, které byly použity při vzorových restaurátorských zásazích, a které je možné aplikovat i na další památky z této skupiny.

Structural differences between rafter and purlin roofs. Summary of vulnerabilities of both types with regard to long-term durability of roof trusses.
Research report from the evaluation of the wooden construction of the movable roof of the garden pavilion Paraplicko in Cesky Krumlov Castle
Kloiber, Michal ; Bláha, Jiří ; Buzek, Jaroslav
The umbrella-shaped roof of the lookout pavilion can be lifted about a meter above the parapet wall by means of a unique lever mechanism. The impulse to write out the report was an order from the Český Krumlov Castle Administration with the seat of the Castle No. 59, Český Krumlov - Latrán which required to assess the condition of all important timber elements using NDT instruments and, in particular, to measure mechanical properties of wood. For that purpose the two apparatuses designed at ITAM were used to measure continually the mechanical resistance during the pressing of the jaws in the drilled hole and the resistance during the pushing of the steel pin to the surface. Gained results should contribute to design a gentle restoration of the unique lifting device

Survey report: Construction and technical assessment of the state of timber, trace analysis and surveying of a timbered barn in Skalička 3
Kloiber, Michal ; Růžička, Petr ; Buzek, Jaroslav ; Hrivnák, Jaroslav ; Bláha, Jiří
Surveys whose aggregate output is this survey report included the determination of the extent of damage to the timber, surveying, and trace analysis of the original craftsman working of a timbered barn belonging to house no. 3 in the village of Skalička u Hranic, which is located in the Přerov district in the Moravian region called Pobečví. The report has been drawn in response to the demand by the Wallachian Open Air Museum located in Rožnov pod Radhoštěm, which contained a request to diagnose the timber elements using NDT devices and carry out their trace analysis. The findings will contribute to a qualified assessment and proposal of a harmless transfer of this unique timbered building.
Principle of public budgets balance legislation
Bláha, Jiří ; Boháč, Radim (advisor) ; Marková, Hana (referee)
PRINCIPLE OF PUBLIC BUDGETS BALANCE LEGISLATION The question of public budgets balance belongs nowadays to the most discussed topics, both on the internal and international fields. Today it is quite evident that constant indebtedness of states affects not only their competetive ability and exercise but also global economic balance. The states with high share of debt in gross domestic products, which often arose in propitious years of economics, acertain that ovecoming of recession in this situation is much more difficult and painful - it is not possible to use surpluses of economic activities from propitious years, other indebtedness comes about and in this way the unfavourable economic situation intensifies. Therefore on the level of individual states and international organizations various measures are accepted, their aim is economic stimulation and resumption of economic growth. In a given case public budgets, especially budgets of individual states, and redistribution of resources accumulated in these budgets become very important. However resources of public budgets are not unlimited and it is necessary to draw a lesson from effects or even better to prevent from repeating previous mistakes again and the principle of public budgets balance comes to the fore. In connection with the question of public...
Budgetary rules and their projection in valid legislation
Bláha, Jiří ; Boháč, Radim (advisor) ; Marková, Hana (referee)
Every branch of law and all system of law is based on certain principles which came into existence by repeated utilization over the years and attested in practises. These principles should affect the existent branch of law and should be followed to be understood well, with the inclusion of thein regularities. However, how do these principles work in such a narrow area such as budget law as a sub-branch of financial law? Which principles do control over budget law and is it possible to find them in existent legal enactments? The thesis entitled Budget Principles in Valid Legal Regulations tries to answer these questions. At the same time the author assumes that by acquiring knowledge of particular budget principles is much easier to get in problems of budget law and of particular stages of budget process - setting of public budgets, budgetary procedure, implementation of budget and also budgetary control. Regarding to the fact that budget principles valid in legal order of the Czech Republic cannot be found completaly modified in any of the valid legal enactment, the main aim of this thesis is to find emergence of these principles or their parts in the legal system of the Czech Republic. However, the situation in the legal system of the European Union is different. Budget principles are there...
