The Effect of Trunk Stabilization Activation on Upper Limb Support in a Healthy Population
No full textMain Objectives: To quantify the influence of trunk stabilization activation according to the DNS concept on hand support in the quadruped and bear positions in healthy individuals. Methodology: This pilot study included 51 healthy volunteers aged 22-58 years. Abdominal wall expansion, representing an indirect indicator of intra-abdominal pressure (IAP), was quantified using the Ohm Belt sensor, which measures mechanical load applied to its surface (in g). The support surface area of the palms (in cmš) was recorded using the PhysioSensing pressure platform. Two positions were assessed - quadruped (on all fours) and bear (with knees elevated 5 cm above the ground). Following the initial measurements, a standardized ten-minute intervention was conducted, including education and manual guidance on activating the deep stabilization system while in a supine position. Subsequently, the measurements in both positions were repeated with an effort to consciously activate trunk stabilization, supported by a pre-recorded verbal instruction. Results: All participants completed the study (23 men, 28 women; mean age 38.8 ± 11.5 years). Trunk activity was significantly higher in the bear position compared to the quadruped position (p < 0.001; d = 1.40). Instructions for trunk activation led to a significant..
Communication skills of preschool twins
No full textABCTRACT This thesis is oriented towards the development of speech and communication competences of preschool-age twins. It focuses on the risks, specifics and difficulties of the development of language abilities, skills and speech in the early and preschool age of twin children. The work is divided into two main parts, theoretical and practical. In the theoretical part, the background to the topic of the thesis is elaborated; professional literature, electronic resources, scientific studies were used. The first and second chapters are devoted to communication, the process of child speech development, the influence of upbringing and educational environment on the development of children's communication abilities and skills. The third and fourth chapters of the theoretical part focus specifically on twins, with an emphasis on the factors affecting the development of communication abilities and skills of twins. The theoretical part of the thesis also focuses on the most common disorders of communication, language and speech development in children in general and in preschool-age twins, as well as on the possibilities of speech therapy intervention in the preschool period. The practical part is focused on the development of communication skills and abilities of twins, at the age before the entry into primary..
The Function of "I" and "you" in the Discourse of Tabletop Roleplaying Games: A Corpus-Assisted Analysis
No full textThis diploma thesis is concerned with the function of the first and second person personal pronouns ("I", "you") in the discourse of tabletop roleplaying games, e.g. Dungeons & Dragons. First and second person personal pronouns are means of personal deixis referring to the speaker and addressee. Attention will be given to cases when the narrator uses the pronoun "you" to refer to players/ characters and when the players refer to themselves (the pronoun "I") or each other (the pronoun "you"). The aim is to identify lexico-grammatical contexts in which the pronouns occur. Considering that deictic uses of the pronouns "I" and "you" serve as a way of expressing the perspective and subjective view of a player/character, this paper aims to describe various strategies when characters or players (and the reference to them) are used for descriptions of the space and time around them and the development of the narrative line of the game (such as using "you" in locative structures, in the function of a subject with verbs of movement and perception or in collocations with expressions describing the mechanics of the game). In order to accomplish this aim, both quantitative and qualitative methods will be utilized, e.g. analyzing collocations, semantic categories and n-grams as well as KWIC analyses of more..
The impact of membership fees on the success of beachvolleyball clubs in Prague
No full textTitle: The Impact of Membership Fees on the Sporting Success of Prague Beach Volleyball Clubs Objective: The aim of this thesis was to determine whether the amount of membership fees influences the sporting performance of youth beach volleyball clubs in the U18 category. The study focused on comparing three Prague-based clubs with different fee levels, club philosophies, and degrees of performance orientation. Methods: The research took the form of a qualitative investigation based on semi- structured interviews with representatives of three Prague clubs, selected from eight respondents who met predefined criteria. The interviews focused on the topics of funding, training conditions and success and were subsequently analysed using thematic analysis. The quantitative part was complemented by results from the U18 Summer and Indoor National Championships in the period 2021-2025. Results: Analysis of the results of the Czech Championship shows that Club A had the most qualified pairs and medal placements in the period under review. Club C was in the middle of the results list, while Club B did not qualify at all in some years. The interviews showed that higher donations allow clubs to offer wider support. However, club philosophy and the way the funds are used also influence success. Club A emphasises..

No full textSurface-Aware Neural Radiance Fields
No full textAccurate and efficient 3D scene reconstruction is a fundamental problem in computer vision, with applications in augmented reality, robotics, and digital heritage preservation. Neural Radiance Fields (NeRFs) have emerged as a powerful learning-based method for photorealistic 3D reconstruction, representing the scene as a learnable radiance field and performing novel view synthesis by sampling opacity and color values from the field. They often rely on memory-intensive representations and ignore geometric priors readily avail- able. To address these issues, Tetra-NeRF recently proposed to use a tetrahedral grid constructed from sparse or dense point clouds via Delaunay triangulation as an adaptive scene representation, which this thesis aims to improve. Based on an experimental analy- sis, we show that reconstruction quality strongly depends on the placement of points near the surface. Hence, we propose a method for adaptive refinement of the tetrahedral grid, introducing pruning and splitting procedures guided by accumulated rendering weights and gradient norms to dynamically reallocate capacity to important regions of the scene. In addition, we propose a Dirichlet-based density weighting to guide the sampling process to focus training near likely surface boundaries. Experiments show that our approach..
Characterization of protein structures beyond natural selection and protein design
No full textProteins derived from random sequence space remain largely unexplored, yet they provide a new perspective on protein folding and evolution. This thesis investigates whether such proteins can adopt defined structural elements and resemble folds of natural proteins without evolutionary optimization. Out of the 21 sequences selected from a combinatorial library of random proteins, 17 were successfully expressed in Escherichia coli, and four were chosen for further characterization. During purification, the proteins exhibited concentration-dependent aggregation and a dynamic equilibrium between monomeric and multimeric forms, suggesting the presence of partially folded molten globule states. Only protein 4 could be purified in sufficient quantity for biophysical analysis. Due to aggregation, protein 4 was purified under denaturing conditions and refolded in the presence of Triton X-100. Circular dichroism spectroscopy revealed predominantly α-helical content with β-sheet elements, consistent with computational structure predictions. The multimeric nature of refolded protein 4, observed by size exclusion chromatography, prevented folding characterization by nuclear magnetic resonance. Nevertheless, the circular dichroism results support that random sequences can form defined secondary structures, and..
Do you hear? I see! Sound in Art education
No full textThe thesis Do You Hear? I See! explores the relationship between auditory perception and visual expression within the context of art education. Its aim is to examine how the ephemeral and often overlooked phenomenon of sound can be translated into visual form and what potential it holds for fostering interdisciplinary thinking among students. The theoretical part defines the concept of sound art, outlines its various typological approaches, and reflects on its position in contemporary artistic and educational contexts. It also includes an analysis of the national curriculum (RVP) with regard to the potential of sound in teaching. The practical part focuses on the implementation and reflection of authorial art lessons in which sound is used as a starting point. Through work with students, their responses, imagination, and ability to visually interpret auditory stimuli were observed. Interviews with gallery educators revealed that incorporating sound into educational practice enhances sensitivity, creativity, and a deeper awareness of the surrounding world. The thesis also offers a working typology of how sound appears in artistic practice, with each category highlighting a different aspect of the relationship between sound, space, body, thought, and media. This confirms the relevance and timeliness..
