The Founders of Post-Keynesianism and the Concept of Reswitching
Kraffer, Robin ; Potužák, Pavel (advisor) ; Chytilová, Helena (referee)
The thesis deals with the evolution of thoughts of Joan Robinson's, Nicholas Kaldor's, Piero Sraffa's and Luigi Pasinetti's with regards to the issue of reswitching. Discussing Robinson, Kaldor, and Sraffa, it addresses the importance of the discussion on imperfect competition and Keynes's theory for developing their opinions within the capital theory. This issue was challenged in the 50s by Robinson who asked how capital can be measured. She discovered an option of reswitching to a more capital-using technique during a wage increase, but she did not focus on it very much. The thesis also seeks the importance of Sraffa's solution to the invariant standard of value for developing the debate on reswitching the technologies in the 60s, which was joined by both Pasinetti and Robinson. However, Robinson refused again in the 70s to deem the reswitching important within the critique of the neoclassical theory, and thus joined Kaldor who had voiced similar thoughts. At the end of the thesis, the question of Robinson underestimating the importance of reswitching, as pronounced by Pasinetti, is answered - she underestimated it in the 50s, whereas it is impossible to give a clear answer when it comes to the 70s, despite the differences found among Post-Keynesians and Neo-Ricardians.

The participation of the nurse in the management of pain therapy by patients with malignant disease
KUČEROVÁ, Miroslava
The topic of this diploma thesis is ?The Nurse?s Contribution to the Management of Pain Treatment of Patients with a Malignant Disease?. The first objective is to ascertain whether nurses know the specifics of care of patients suffering from a cancer pain. The second objective is to ascertain whether nurses use an analogue score to assess the cancer pain. The third objective is to ascertain whether nurses document the pain intensity. The fourth objective is to ascertain whether nurses use non-pharmacological techniques to relieve cancer pains. The fifth objective is to ascertain whether nurses know the strategy of the WHO?s pain relief ladder. The research was conducted in the form of questioning while using the technique of anonymous structured questionnaires completed by the research set consisting of nurses in selected clinical wards with a high probability of occurrence of patients with an oncologic diagnosis. The total of 360 questionnaires was distributed, of which 198 completed questionnaires were returned. 105 questionnaires (53 %) came from the regional hospital in České Budějovice, 51 (26 %) from the St. Anne?s University Hospital in Brno and 42 (21 %) from the district hospital in Tábor. The research took place in March 2012. The results were assessed under the criteria preset by the author of the thesis. Hypothesis 1: Nurses are able to provide specific nursing care to patients suffering from a cancer pain, was confirmed. Hypothesis 2: Nurses assess the pain under the available analogue scores, was confirmed. Hypothesis 3: Nurses document the pain intensity, was disconfirmed. Hypothesis 4: Nurses use non-pharmacological techniques, especially physical ones, was confirmed. Hypothesis 5: Nurses know the strategy of the WHO?s pain relief ladder, was confirmed. In connection with the addressed issue, an educational leaflet about pain monitoring was drawn up for non-medical healthcare workers. This material describes the most frequently used methods of pain assessment and will serve as an overview of individual procedures including their specifics and application possibilities. The diploma thesis may serve for extending the knowledge of nurses in the field of pain treatment management.

CNC Programming if the Single Point Incremental Forming
Ladecký, Tomáš ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
V současné době se zvyšuje potřeba rozvoje agilních výrobních postupů, které lze snadno přizpůsobit neustálému zavádění nových produktů na trh. Jednobodové inkrementální tváření je nový, inovativní a proveditelný tvářecí proces s jednoduchým uspořádáním. Proces se provádí při pokojové teplotě (tváření za studena) a vyžaduje CNC stroj, nástroj s kulovou hlavou a jednoduché příslušenství pro uchycení obrobku plechu. V samotném procesu jde o přírůstkové formování, řízené CNC programem. Plastická deformace je lokalizována pod formovacím nástrojem takže plech je tvářen souhrnem pohybů lokální plastické zóny. Tento proces je zdlouhavý a proto se hodí pouze pro prototypovou výrobu nebo pro malé výrobní dávky. Na druhé straně umožňuje vyšší tvářitelnost ve srovnání s konvenčními procesy tváření, umožňuje použití levných nástrojů a také je charakterizován krátkou dobou od návrhu po výrobu produktu. Tato práce je výsledkem mezinárodní spolupráce Danmarks Tekniske Universitet v Lyngby a Instituto Superior Técnico v Lisabonu. Práce začíná krátkým hodnocením dílčích tvářecích procesů, pokračuje představováním jednobodového inkrementálního tváření a identifikací jeho praktických aplikací. Teoretická část obsahuje přehled nového rámce pro jednobodové inkrementální tváření, který je vytvořen na základě analýzy styku třecích sil. Praktická část projektu poskytuje úplný popis experimentálních technik použitých pro charakterizaci materiálů a stanovení limitů tvářitelnosti, dále se analyzuje vliv různých vstupních parametrů procesu (poloměru nástroje, tepelné zpracování materiálu obrobku, druh maziva,...). Tato část také obsahuje přehled experimentálního uspořádaní procesu jednobodového inkrementálního tváření i krátký popis CAD / CAM vývoje tří testovacích modelů. Poté jsou popsány v samostatné kapitole výsledky pozorování a analýzy hlavních parametrů procesů, které ovlivňují tvařitelnostní limity v jednobodovém inkrementálním tváření v souvislosti s aplikovaným teoretickým rámcem. Výsledky experimentů z časti objasňují probíhající mezinárodní diskusi kolem tvářitelnosti mechanismu jednobodového inkrementálního tváření vzhledem k tradičním metodám tváření. Jako logické pokračování prováděných experimentů, byla práce rozšířena na více-stupňové jednobodové inkrementální tváření, které umožňuje tváření součástek (kalíšku) se svislými stěnami ve více krocích. Za účelem objasnění procesů spojených s tímhle procesem byly navrženy a ve čtyřech krocích vyrobeny dva experimentální modely. Hlavním přínosem této práce k více-stupňovému jednobodovému inkrementálnímu tváření byla úspěšná výroba součásti s nekruhovým průřezem a kolmými stěnami. S cílem aplikovat celkové znalosti získáných v předchozích částí práce byla vyrobena prototypová součást. Popis designu a vývoje prototypu je součástí práce. V neposlední řadě jsou celkové závěry uvedené v poslední kapitole. Předpokládá se, že tato práce přizpívá k lepšímu pochopení mechanismu jednobodového inkrementálního tváření.
