Multi-parameter MTS and SED criterion applied on a crack in an alkali-activated concrete specimen under mixed-mode loading
Malíková, Lucie ; Miarka, Petr ; Šimonová, H.
The paper is devoted to an analysis of a crack propagation in a semi-circular concrete specimen under three-point bending. I+II mixed-mode loading is ensured via an inclined crack. Crack deflection angle is investigated by means of the generalized/multi-parameter form of the Maximum Tangential Stress (MTS) criterion and Strain Energy Density (SED) criterion as well as experimentally. The multi-parameter fracture mechanics concept applied in this work is based on the approximation of the crack-tip stress field by means of the Williams series expansion (WE). It has been proved that this approach can help to describe crack behavior in some kinds of materials better than the classical (one-parameter: stress intensity factor) fracture mechanics. This conclusion is discussed also in this paper.

UV dosimeter for safer sunbath
Hinca, Sven Barbara ; Králová, Marcela (referee) ; Veselý, Michal (advisor)
V dnešní době je veřejnost konstantně vystavená slunečímu světlu a tím také UV záření. Protože UV radiace je prokázaným karcinogenem a kvůli rapidnímu zmenšování ozonové vrstvy v nedávné minulosti, monitorování osobního vystavení UV záření, a povědomí o riskantnosti ozáření vyššího než je bezpečná dávka, je důležitější než kdykoliv předtím. Tato práce je zaměřená na vývoj a zjednodušení osobní UV dozimetrie pro použití veřejností tak, aby každý uměl vyhodnotit riskantnost delšího vystavení UV radiaci.

The 1972 Interruption of Pregnancy Law in the context of the family and women's policy of the GDR
Sklenková, Kateřina ; Kunštát, Miroslav (advisor) ; Nigrin, Tomáš (referee)
Kateřina Sklenková: "The 1972 Interruption of Pregnancy Law in the context of the family and women's policy of the GDR." Abstract The Bachelor's thesis focuses on the Interruptionof Pregnancy Law of 1972, which was the only law in East Germany that was passed unanimously. It gave women the option to terminate a pregnancy during its first 12 weeks without any indication.There were ambivalent views in society about this practice. After numerous protests, the churches were granted an exemptionand abortioncould be denied on the basis of faith.In the wave of resistance that rose when it became apparent that artificial terminations of pregnancy would be criminalisedagain in the process of German unification, it can be seen that the Law was generally viewed positively.The thesis places the Law in its historical context and in the context of the regime's other family and emancipation policies This text answers the question of how it was possible that such a liberal norm was in place in the GDR. It explains that there were multiple factors. First, it was the socialist regime itself, which was supposed to be scientific and egalitarian in the spirit of the Marxist revolution. Then there was pressure from within the state, where the restrictive policywas criticisedbythe general public, backed by professional...

Influence of compensatory mechanisms arising from violin playing using the DNS method
Hryzlíková, Eliška ; Oplatková, Lenka (advisor) ; Pelíšková, Pavlína (referee)
This thesis investigates compensatory mechanisms arising from playing the violin. It summarizes the existing literature on the topic of the influence of violin playing on the posture of violinists and proposes a compensatory exercise according to the DNS method. The theoretical part describes the "ideal" position for violin playing, the effect of ergonomic aids, kinesiology of playing, anatomy of the shoulder girdle, and finally the compensatory mechanisms stemming from holding and playing the violin while sitting and connected health problems. The experimental part presents the results of case studies of 8 non-professional violin players aged from 18 to 30 years, evaluation of their posture and musculoskeletal disorders, and the proposed compensatory exercise according to the DNS method. The anamnestic data were obtained through a survey and the health condition of the musculoskeletal system is investigated using a kinesiological examination (inspection and palpation, anthropometric measurements, and specific tests for deep stabilizing system and scapula). Inspection and palpation measurement cannot be objectively measured and therefore the obtained measurements serve only as a relative guide for the evaluation. The greatest muscle load is generally in the areas of cervical spine and shoulder...

Back pain of working people
ZELENKOVÁ, Benedikta
This bachelor thesis deals with low-back pain in patients who are mostly sitting at work. The thesis is divided into two main parts, theoretical and practical. In the theoretical part, the function, anatomy and kinesiology of the spine are first described. It also explains the deep stabilization system, its importance and its examinations. Further, most common causes of vertebrogenic problems are described and the word pain itself together with is explained. In this part, pain is divided into several categories. In conclusion, individual examinations and possibilities of therapy in back pain are described. Individual examinations are also included in kinesiological analyzes of all patients. The practical part of the thesis was done in a form of qualitative research. The examined group consists of three respondents men in between 45 and 55 years who were suitable figures for this work. Two patients were patients from rehabilitation center in Borovany where I had the opportunity to work with them and the third patient is a member of my family and I worked with him at home. This part consists of elaborated case studies of individual patients, proposed therapies and their description and physiotherapeutic examinations after all therapies. The main aim of this work was to describe the possibilities of physiotherapy treatment in people with sedentary job suffering from back pain. The second objective was to map the problem, propose suitable therapy, and then evaluate its effect. I met with patients six times in six weeks. I stressed the importance of proper posture while sitting, standing and lifting heavy loads. All patients were well educated on this issue. Crucial is also regularity of the proposed exercises, which all can be done at home. The success of the therapy was evaluated by subjective patient's assessment and by comparison of kinesiology carried out before the start and after the end of the whole therapy. This allows me to state that both objectives of the work have been met.

Physiotherapy for patiens with sedentary jobs suffering recurrent pain in the cervical spine
HAVLÍČEK, Diana
This Bachelor thesis is about the issue of repeated pain in the cervical spin at patient with sedentary occupation. The aim of my work was to delineate the possibilities of various methods of physiotherapy and kinesiotherapy in the form of a complex therapeutic plan and to devise a set of exercises serving not only for therapy but also prevention of functional defects in the area of the cervical spine. I choose mostly from methodologies I met during my studies and convinced of their abilities. Inn the theoretical part there is a great attention focused to anatomy, function of cervical spine and functional disorders in this area. certain degree of importance has also been focused in describing the ergonomics of seduction and correct body shifting during sitting in the working process. Conclusion of the theoretical part creates selected physiotherapeutic procedures for the treatment of pain in the cervical spine at patients with sedentary occupations. The practical part was created thanks to the method of high quality, which was elaborated in the form of causes of three women from the age 45 to 50 years. They worked in a job requiring sitting at a minimum of eight hours a day, five days a week. These women had an input kinesiology analysis supplemented with a photographic documentation. On its basis was made a comprehensive therapeutics plan with individual therapies which was taking place once a week for two months. At the same time, they received a set of exercises, which were selected with regard to the possibilities of their everyday implementation at the office during their working hours. At the end of the research there was done an output examination. It was completed with photos and the subjective assessment of the condition and feelings of respondents. This bachelor thesis can be helpful not only for physiotherapists in the clinical practice dealing with problems of repeated cervical spine pains in patients with sedentary occupation, but also for the general people who can be in the state of endangerment of the origin of this prolact or by its permeability.

Nazi Anti-Semitism Remembered: Jewish Memorials in the SBZ and GDR between the Years 1945-1987
McQuiggan, Sean ; Emler, David (advisor) ; Šmidrkal, Václav (referee)
The thesis is an exploration into the Jewish memorial sites erected in the Soviet Zone of Occupation (SBZ) and German Democratic Republic (GDR) between the years 1945 and 1987. The primary aim of the thesis is to provide a collection of Jewish memorial sites in East Germany during the aforementioned time frame. It uses the theories of French historian Pierre Nora as well a number of other authors to legitimize the importance of these memorial sites. In addition, a typology was created by the author to ensure the proper collection of the memorial sites in order to reflect the research question: how was Nazi anti-Semitism remembered in the German Democratic Republic (GDR) through memorial sites between the years 1945-1987? The thesis is, however, more than just a collection of data. It also provides observations about trends and patterns in Jewish memorialization as well uses a method introduced by Ahenk Yilmaz to examine the individual characteristics of the sites. The thesis concludes that Jewish memorialization in the GDR was primarily a bottom-up approach, a fact that has been overlooked by many researchers in the field.
