Les malalties cardiovasculars són una de les principals causes de mortalitat als països desenvolupats. La majoria d'elles són degudes a malalties arterials (especialment les coron ries), que vénen causades per l'acumulació de placa. Aquesta patologia estreny el flux sanguini (estenosi) i afecta les propietats elàstiques i bio-mecàniques (arteriosclerosi) de les artèries. En les últimes dècades, l'Ecografia Intra-Coronària (EIC) ha esdevingut una tècnica usual de diagnòstic per la imatge i seguiment de les malalties coronàries. L'EIC està basada en un cateterisme que mostra una seqüència d'imatges corresponents a seccions de l'artèria sota estudi. La inspecció visual de cadascuna d'aquestes imatges proporciona informació sobre el percentatge d'estenosi, mentre que la inspecció de les vistes longitudinals propociona informació sobre les propietats bio-mecàniques, que pot prevenir un desenllaç fatal de la malaltia cardiovascular. Per una banda, la dinàmica arterial (deguda al batec del cor, entre d'altres) és un dels principals artefactes per poder explorar les propietats biomecàniques. Al mateix temps, les mesures manuals d'estenosi requereixen un traçat manual de les vores del vas, tasca feixuga que consumeix molt de temps i que pot patir variabilitat entre observadors.Aquesta tesi proposa vàries eines de processament d'imatge per explorar la dinàmica de les artèries i les seves estructures. Presentem un model físic per extreure, analitzar i corregir la dinàmica rígida transversal dels vasos i per recuperar la fase cardíaca. A més, introduïm un mètode estadístic-determinista per a la detecció automàtica de les vores del vas. En particular, l'enfoquem a segmentar l'adventícia. Un protocol de validació acurat per assegurar una aplicació clínica fiable dels mètodes és un pas crucial en qualsevol proposta d'algorisme. En aquesta tesi tenim especial cura de dissenyar protocols de validació per a cadascuna de les tècniques proposades i contribuïmm a la validació de la dinàmica in vivo amb un indicador objectiu i quantitatiu per mesurar la quantitat de moviment suprimida. / Cardiovascular diseases are a leading cause of death in developed countries. Most of them are caused by arterial (specially coronary) diseases, mainly caused by plaque accumulation. Such pathology narrows blood flow (stenosis) and affects artery bio-mechanical elastic properties (atherosclerosis). In the last decades, IntraVascular UltraSound (IVUS) has become a usual imaging technique for the diagnosis and follow up of arterial diseases. IVUS is a catheter-based imaging technique which shows a sequence of cross sections of the artery under study. Inspection of a single image gives information about the percentage of stenosis. Meanwhile, inspection of longitudinal views provides information about artery bio-mechanical properties, which can prevent a fatal outcome of the cardiovascular disease. On one hand, dynamics of arteries (due to heart pumping among others) is a major artifact for exploring tissue bio-mechanical properties. On the other one, manual stenosis measurements require a manual tracing of vessel borders, which is a time-consuming task and might suffer from inter-observer variations.This PhD thesis proposes several image processing tools for exploring vessel dynamics and structures. We present a physics-based model to extract, analyze and correct vessel in-plane rigid dynamics and to retrieve cardiac phase. Furthermore, we introduce a deterministic-statistical method for automatic vessel borders detection. In particular, we address adventitia layer segmentation. An accurate validation protocol to ensure reliable clinical applicability of the methods is a crucial step in any proposal of an algorithm. In this thesis we take special care in designing a validation protocol for each approach proposed and we contribute to the in vivo dynamics validation with a quantitative and objective score to measure the amount of motion suppressed.

The diploma thesis deals with medial images of selected events of the Ukraine War and their comparison in selected Ukrainian, Russian and Czech media. The aim of the diploma thesis is to identify, describe and compare medial images of key events of the Ukraine War in selected intelligence portals with various political orientation. The assumption is that there probably exist alternatives in opinion of the official Russian position in the frame of the Ukrainian and Czech media discourse. The first part of the thesis deals with theoretical concepts that are connected with propaganda and state-organised communication, and specifies the differences among them. Furthermore, a design of the research is introduced. The analytical part provides results and the content analysis detections in medial statements that were published in selected media between 20th February 2014 and 31st December 2014. The conclusion summarises the main detections of the research and their assets in the field of a propaganda survey.

This diploma thesis deals with the medial image of civil society and non governmet organisations in three main daily papers in Slovakia(Sme, Pravda, Hospodárske noviny). Thesis tries to answer the question - what kind of medial image were mentioned daily papers forming and publishing. Thesis also deals with the biggest non-governmental organisation in Slovakia - Košice - European capital of culture 2013 and its role and influence in that medial image. Im using method of contentual analysis. Im comparing this media image during two periods - January 2007 and January 2013.

The thesis is aimed on the role of seniors in the society of the west type with the stress on the society in the Czech Republic. In the theoretical part there is discussed the problematic of active life-conception in old years as the important condition of social health of both senior-ladies and senior-men. In next section there are presented myths having the base in the oldness and there are outlined the possibilities that seniors have in this area in the Czech Republic. Further, in the work there are discussed main problems that seniors have in recent society preferring youthfulness and sexual activity.In the practical part of the thesis there are presented some significant results of the research ``Senior-women in Roman Catholic Church{\crqq} that surveys the active life-conception, life style and life-contentment of its members older than sixty five years. There is discussed the influence of dissimilarities having the base in the difference in education or social status of senior-women or whether they live in the city or in a small village.
