Postural stability of near-sighted people
 Palivcová, Lenka ; Zahálka, František (advisor) ; Nováková, Tereza (referee)
Title: Postural stability of near-sighted people Objectives: To analyse relationships between selected parameters of postural stability and impaired visual acuity (myopia), which is revised by optimal visual correction, by diffusing glasses or by contact lenses. Methods: Investigations of stabilizing capabilities of erected posture in its various modifications. An objective measuring was performed by stabilometric platform type Footscan. The experiment involved twelve people with myopia of -3 to -6D visual acuity of an average age of 23 ± 4 years. Myopat group of bipedal standing position were tested with open eyes with vision correction, afterwards with eyes closed, then without any vision correction. The last measured positions were performed on one lower limb with visual correction and then without it. Total number of measured positions were ten upright positions, each of which was measured with 30 second interval. Results: A total travelled way of centre of pressure was determined as a parameter of postural stability evaluating. Positions on one lower limb clearly put the highest demands for stabilizing upright positions. The only aggravation of conditions stabilizing this position should be to eliminate vision correction, which was confirmed in 8 probands from a total of 12. Under a bipedal...

Modern diagnostic methods use in defectoscopy
 Vítámvás, Zdeněk ; Stránský, Lubomír (referee) ; Juliš, Martin (advisor)
Nowadays non-destructive testing offers various ways to detection defects in material. By selecting of suitable method or suitable combination of tests we can locate the defect and determine size of defect with sufficient accuracy. For higher probability of detect defects and for easier operation and evaluation are still evolve new ways of inspection. There are summarizes both ordinarily and modern methods using in defectoscopy in this work. There are describe its principles, courses of testing, suitability of use and there are drop next general information.
