Analysis of AVG signal

Bakalářská práce se zabývá analýzou signálu AVG (arteriovelocitogramu). Naměřená data vypovídají o rychlosti a charakteristice průtoku krve tepnami lidského těla. Signál je získáván ultrazvukovým měřením, využívá se odrazu mechanického vlnění od pohybující se tkáně a následné změny frekvence. Tento fenomén nazýváme Dopplerův jev. Na základě provedené analýzy určujeme přítomnost a stupeň ischemické choroby. K samotné klasifikaci dat byla použita metoda shlukové analýzy. Vyhodnocovací algoritmus pracuje v programovacím prostředí MATLAB.Bachelor´s thesis deals with analysis of AVG signal (arteriovelocitogram). Measured data predicate about speed and caracteristic of blood flow in human arteria. Signal is taken by ultrasound mesure. We use reflection of mechanic wave from moving objets followed by a chase of frequence. This fenomen is called Doppler effect. When we know analysis results we can diagnostic the existence and phase of ischemic desease. The clasification of the dates was made by methods of cluster analysis. Statistic algorithm was realised in programing world MATLAB.

Post-war Co-operation between the Union of Czechs and Slovaks in the SR of Croatia and Czechoslovakia

Poslijeratna suradnja Saveza Čeha i Slovaka u Hrvatskoj sa ČSSR prolazila je tokom vremena razdoblja uspona i padova, u ovisnosti o stanju bilateralnih odnosa Jugoslavije i Čehoslovačke. Pod političko-institucionalnom suradnjom podrazumijevaju se kontakti Saveza sa čehoslovačkim institucijama, te političkim predstavnicima, kao i cjelokupni spektar međusobnih političkih odnosa, koji se vremenski može podijeliti na četiri razdoblja: 1945–1948 (značajan faktor prekida suradnje jest rezolucija IB-a), 1948–1956 i 1956–1973., te od 1973. do danas. Tokom vremena mijenjali su se kako sadržaji, tako i oblici ove vrste suradnje. Kulturna suradnja obuhvaća šire područje kulturno-umjetničkih aktivnosti: gostovanja umjetničkih grupa iz Čehoslovačke, gostovanje ansambala pripadnika narodnosti u matičnoj zemlji, rad instruktora iz ČSSR s tim ansamblima na području Hrvatske, te nabavka knjiga, muzikalija, gramofonskih ploča i instruktivnog materijala iz ČSSR. Ova vrsta suradnje počinje praktično od 1956. Suradnja s područja školstva i njegovanja jezika odnosi se na seminare za nastavnike iz škola narodnosti u ČSSR i na ekskurzije, te na plasiranje elemenata jezika matične zemlje putem kulturne suradnje. Ova vrsta suradnje počinje 1958. U nju treba ubrojiti i studij pripadnika narodnosti u ČSSR.Post-war co-operation between the Union of Czechs and Slovaks in Croatia and the Czechoslovak Socialist Republic passed through periods of expansion and reduction depending on the state of bilateral relations between Yugoslavia and Czechoslovakia. Political-institutional co-operation included contracts between the Union and Czechoslovak institutions, between political representatives, as well as the entire spectrum of mutual political relations which can be chronologically divided into four periods: 1945–1948 (a significant factor in the discontinuation of co-operation was the resolution of the Information Bureau), 1948–1956, 1956–1973, and 1973 until the present. The contents and forms of this type of co-operation changed through time. Cultural co-operation included a wider field of cultural and artistic activities: visits by Czechoslovak artistic groups, visits to the old homeland by Czech and Slovak ensembles from Croatia, assistance given by instructors from the CSSR to ensembles in Croatia, the sending of books, musical material, gramophone records and instruction material from the CSSR. This type of co-operation practically began in 1956. Co-operation in the field of schooling and mother tongue maintenance involved the organisation of seminars in the CSSR for teachers from the nationality schools in Croatia, excursions and the influencing of Czech and Slovak speech in Croatia by recurring acquaintance with cultural elements from the old homeland. This form of co-operation began in 1958. Czech and Slovak students from Croatia studying in the CSSR were also a part of this type of co-operation

The Culture of the Czech Nationality in SR Croatia at the Moment

Poslijeratni društveno-ekonomski razvoj Jugoslavije značajno je utjecao na organiziranost i kulturni život češke narodnosti u SR Hrvatskoj. Unutrašnje migracije dovele su do odlaska mladih sa sela, a reemigracija u Čehoslovačku bila je uzrok odlaska najkreativnijih i najistaknutijih ličnosti. Rezultat tih procesa bio je ograničavanje ljudskog faktora i baze dotadašnjih središta narodnosti, kao i pad kvalitete kulturnih aktivnosti. Razvoj i prodor masovne kulture pridonio je izraženom padu interesa za kulturne aktivnosti i za radom u društvima. Za razliku od prijeratnog razdoblja, danas glavnu osovinu kulturnog života Čeha ne čini više raznovrstan rad u društvima, nego velike manifestacije tipa smotri (npr. »Žetvene svečanosti«). U većini društava kulturne se aktivnosti obavljaju u skladu s programom nastupa na smotrama, ali samostalnog kontinuiranog rada nema. Najveći problem jest animirati omladinu da se bavi kulturnim radom. Glavne kulturne aktivnosti jesu njegovanje folklora, dramski amaterizam i estradne priredbe, te koncerti duhačkih orkestara. U te aktivnosti omladina se uključuje ovisno o njihovoj privlačnosti. U zadnje dvije godine pokazalo se da u radu sa mladima najveće uspjehe postižu sekcije ili grupe pod vodstvom mladih voditelja koji preferiraju suvremeniji način rada, te aktualniji repertoar. Značajnu ulogu u kulturnom životu Čeha ima Savez Čeha i Slovaka, koji putem savjeta koordinira i osmišljava sav kulturni život narodnosti. Manifestacije i smotre u središtu su pažnje Saveza, koji radi podizanja kvalitete surađuje s odgovarajućim ustanovama u nas i u ČSSR. Za bolje osmišljavanje kulturnog života Savez bi ipak trebao precizirati dugoročniju i racionalnu kulturnu politiku, kojom bi se više poticao kontinuiran i stalniji rad u društvima, kako manifestacije ne bi bile svrha sebi.The postwar social and economic development of Yugoslavia has had an impact on the manner in which the cultural life of the Czech nationality in SR Croatia is organised. Internal migration has led the youth out of villages, and re-migration to Czechoslovakia has brought about the departures of the most creative and most eminent personalities. This has resulted in a restriction of the “human factor” and of the base of the former venues of the nationality, as well as a decline in the quality of cultural activities. The advance and breakthrough of mass culture has contributed to a pronounced drop in the nationality\u27s interest in cultural activities and work in societies. Unlike the prewar period that was characterised by diverse activities in soci¬eties, the backbone of today\u27s cultural life of the Czechs are grand convention-type manifestations (i e. harvest festivals). In the majority of societies cultural activities take place in accordance with planned participation in such manifestations, but there is no independent continuous work. The major problem is to win over young people for engaging in culture-related work. The main cultural activities are: folklore events, amateur drama and entertainments, as well as wind music concerts. The youth get included in those if they are attractive enough. In the past two years it has become obvious that the most successful at work with the young are the so-called sections or groups guided by young leaders who prefer more modem work methods and a more up-to-date repertoire. An important role in the cultural life of Czechs is played by the Alliance of Czechs and Slovaks, coordinating and enlivening the entire cultural life of the na¬tionality by means of a council. In the focus of the Alliance\u27s attention are manifestations and festivals. To improve their quality, the Alliance has co-operation with its counterpart institutions in this country and in Czechoslovakia. In order to make the minority\u27s cultural life more meaningful, however, the Alliance should work out a longer-term and more rational cultural policy so as to encourage work in societies on a continuous and more permanent basis and to prevent manifestations from being a means to their own end
