The paper maps the use of the principle of randomness in artistic activity with a focus on visual art and the placement of Czech art into the world context. It examines the hypothesis whether randomness in the hands of the artist becomes an instrument to objectify his or her work and to approach the general principles of the natural world, which, according to the assumption, add novelty and consequently increases its artistic value. The text begins with an etymological interpretation of the concept of randomness, further observes the randomness as phenomenon in various social spheres, and eventually presents the artistic movements and artworks that systematically use randomness. An overview of avant-garde art and abstraction of the first half of the 20th century will allow the author to interpret the principles of randomness used in computer art. The work concludes with a detailed analysis of Zdeněk Sýkora's work, in which, according to the author, the development line of precomputational art is mirrored, along with a breakthrough to digital tools. The conclusion of the work reveals the diversity of the application of the principle of randomness in the art world and finds a common divisor in the objectivizing function, respectively the rising aesthetic value. Through this interpretation, Zdeněk...

This thesis is focusing on objectifying the postural function of diaphragm with a biofeedback sensor in patients with low back pain (LBP). The theoretical part provides an overview of known facts about the postural function of the abdominal muscles and diaphragm and the connection between their activation and the change in intra-abdominal pressure and the origin of LBP. The thesis gives specifics of LBP, its etiology and possible methods of classification of non-specific LBP, as well as the methods of evaluating subjective disability. Other methods of objectifying postural functions other than the one used in this thesis are mentioned briefly. Methodology: In the experimental part, we used a capacitive force sensor to test 31 patients with non-specific chronic LBP (aver. age 25.25, SD ± 4.66, aver. height 176.77 cm, SD ± 9.97, aver. weight 77.93 kg, SD ±18.40) in 3 posturally different seated scenarios - resting breathing, with added external load when the subjects held a dumbbell of 20 % of their body weight) and with maximum voluntary increase in intra-abdominal pressure (the diaphragm test). The sensor position was on lumbar triangle and in the groin area. Oswestry Questionaire v2.1a was used to evaluate subjective disability. Results: An independent t-test analysis showes increase in the...

This paper is devoted to a critical analysis of the book I and Thou in the attempt to identify the main points of the dialogical philosophy as presented by Martin Buber. The introductory passages present the background of the book in terms of time (the era after WWI), cultural background (the influence of Hasidism), or the history of philosophy (an opposition to immanentism, monism, idealism, transcendental philosophy etc.). The main goal of the following interpretation is to try to understand man as a person in his complex existential situation, i.e. through his potential relationships or objectifying attitudes to the world. Being is described as a dual structure either of the basic pair of words I-Thou or of the basic pair of words I-It. As opposed to the usual use of the term, dialogue is defined as a specific interaction of man and the remaining world metaphorically expressible by the structure of addressing-responding. By this scheme, the characteristic reciprocity and direct continuity is expressed. The dialogue is also placed in the area "between" I and Thou, which mediates the genuine, immediate and transcendental knowledge constituting the reality. Finally, the dialogical attitude is compared and contrasted to the monological comprehension of the world. Key words: personalism, dialogical...
