Increasis in utillity value ingreecing by agrocultural products
SABOLOVÁ, Jana
Only few people are currently able to grow own food and therefore the use of substances that increase the durability of food products becomes almost inevitable. Additives which are added to foodstuffs fill several profitable functions that we as consumers of these products often take for granted. There are manifold reasons for using the additives, in particular provision of food safety and freshness, enhancing or maintaining of nutritional value, sensoric value, and simplification of the food availability to consumers. For these reasons, additional substances became an integral part of our lives.

Agrotechnology of cultivation and content of some biologically active substances in the plants of Silybum Marianum (L.) Gaertn.
KOBLIC, Petr
The milk thistle plant has been known for several thousand years. People observed its beneficial effects for human body as early as in the ancient times. The aim of my work was to study the influence of agricultural technologies to the content of biologically active substances in this plant. I dealt with agrotechnical procedures and climatic conditions which largely influence the content of silymarin complex in achenes of the monitored plant. I gained information in available resources from various authors. Furthermore, in my undergraduate thesis I attempted to clarify some of the methods for the determination of active substances in milk thistle. These active substances are influenced by elicitors. Some of them are described in the next part of my work. In conclusion I evaluated the small plot attempt and the economic evaluation of the proposed technology of growing the plants.

TUL team participated in Task C1 (THMC processes in a single fracture) using the software Geochemist’s Workbench and their own tool TrAper for connecting chemistry and deformation and Task C2 (flow and transport in the vicinity of the tunnel Bedřichov) using Flow123d software. Task C2 also includes the formulation of the assignment and coordination of the solution of other teams. The ÚGN team participated in Task A, focusing on saturation of bentonite seals in clay rock and closing the gap, with the help of the COMSOL Multiphysics software. The outputs are the joint report by international teams and papers in a special issue of a journal. The developed models and lessons learned contribute to the ability to predict phenomena in the deep geological repository. Another result is a set of documents for the Flow123d software. All of which are attached to the report as attachments.

Terms of trade: impact on the czech international trade and economic growth in 2005 - 2015
Dulovec, Adam ; Zamrazilová, Eva (advisor) ; Šimíček, Petr (referee)
The thesis is focused on the changes in the terms of trade in Czech international trade in the term of from 2005 to 2015, as the period after the Czech Republic joined the European Union. The terms of trade are an important indicator of the benefits and loses of international trade. The main aim is to analyze the changes of terms of trade, the causes of their changes, and the impact on the real economy. The direction of the overall terms of trade index was highly unsettled, and did not actually generated additional gains in the economy not over the reporting period. The overall terms of trades were most influenced by the price development of two groups of the Standard International Trade Classification, Crude materials and lubricants, and machinery and transport equipment. The prices of Crude materials and lubricants are determined mainly by changes in the oil prices. These were very volatile in the reporting period, the especially the collapse of the prices in both 2009 and 2014-2015, had a significant impact on the import prices of the Czech economy. The thesis also analyzes the impact of exchange rate on the international trade prices, in the period since November 2013, i.e. after the Czech National Bank has committed to maintain the rate of Czech koruna against the Euro above the level of 27 CZK/EUR, which helped to protect the economy from deflations and enhance the economic growth. The effect of the weak crown, that favored the Czech exporters, however a faded over time.

Perceptions of addictive substance of senior population.
MATOUŠKOVÁ, Monika
Diplomová práce se zabývá vnímáním návykových látek seniorskou populací. Jejím záměrem je především odhalení postojů a pohledů seniorů vůči nim. Cílem práce je zjistit, jak senioři znají a nahlíží na legální i nelegální návykové látky. Jaké s nimi mají zkušenosti a jak by se zachovali při případném střetu s nimi, či jejich uživateli. A v závěru objasnit, co za jejich rozdílnými postoji stojí. Teoretická část práce se zaměřuje na současný stav dané problematiky. Hlavní pozornost je věnována kapitolám: charakteristika stavu stáří a procesu stárnutí, populační stárnutí, změny spojené se stářím a návykové látky. Teoretickou část ukončují stěžejní kapitoly zabývající se vývojem užívání návykových látek v ČR po roce 1918 a senior jako potencionální uživatel. Pro naplnění cílů práce byl vybrán kvalitativní výzkum ve formě polostandardizovaného rozhovoru. Pro sběr dat byla použita technika dotazování s otevřeně formulovanými otázkami. Hlavními parametry pro výběr dotazovaných byl věk, pohlaví, bydliště a způsob bydlení. Náhodným výběrem byli vybráni respondenti ve dvou věkových kategoriích 60-75 let a 75let a více, ženy i muži. Ve výběru bylo přihlédnuto i k místu bydliště, zda respondenti pochází z velkoměsta či z maloměsta a zda přebývají v domácím prostředí či v institucích zajišťující sociální péči. Výzkumná část se věnuje jednotlivým výpovědím respondentů, které jsou pro lepší přehlednost graficky zpracovány. Celkový autentický přepis rozhovorů je umístěn v kapitole přílohy. Získané informace jsou dále analyzovány v kapitole diskuze. Výsledky výzkumu ukázaly velmi široké a různorodé nazírání seniorské populace na návykové látky. Ač se výpovědi respondentů v různých niancích lišily, v důležitých stanoviscích zůstávaly v podstatě stejné. Výběr respondentů poskytl rozsah, který v práci ukázal i problematiku závislostí v seniorském věku či překvapivé nahlížení seniorů na legalizaci marihuany. Získané výsledky diplomové práce by mohly dále posloužit jako drobný příspěvek ke zpracování edukativní intervence v seniorské populaci.
