Detecting JavaScript Code with Known Vulnerabilites
Randýsek, Vojtěch ; Jeřábek, Kamil (referee) ; Polčák, Libor (advisor)
This thesis deals with the detection of vulnerable JavaScript libraries and NPM packages. Based on existing studies, it summarizes the technological core of the Node.js platform and further focuses on selected vulnerabilities of the NPM system and existing means of protection. A Chrome browser extension able to detect and fix JavaScript code with known vulnerabilities on the web browser had been introduced. The tool was tested in a crawl of 50 000 websites. 8 129 vulnerable scripts were detected. The extension has been published to the Chrome Web Store as JS Vulnerability Detector .

Dastychová, Martina ; Chvostek, Lukáš (advisor) ; Svobodová, Irena (referee)
Title: The most common mistakes in crawl swimming in second and third school year from Benešov district and their remedy. Objective: The aim of this work will be to determine the most common mistakes that children in seconad and third grades make in the technical execution of the crawl swimming stroke. Methods: The research conducted for this work was supervised by the supervisor of the work, and an evaluation scale was used during the pocess. The obtained results were taken down in tabels and graph for clarity. Results: Based on the evaluation of the used scale, the most frequently recurring errors in the given movement category were revealed. In the correct body position, students made mistakes by the positioning their bodies incorrectly so that the water level crossed their forehead while swimming. In the activity of the upper limbs, the incorrect submersion of the arm dominated, which did not occur at the shoulder level. In the lower limbs, irregular movement and coordination prevailed. Regardless of gender, two most common mistakes were observed in breathing - students did not breath to the side and were unable to time inhalation correctly. KEY WORDS: swimming, crawl, mistakes in swimming, rating scale, swimming school, remedial exercises, younger school age

Teaching children the freestyle swimming stroke
Vajglová, Kateřina ; Svobodová, Irena (advisor) ; Kuhnová, Věra (referee)
The aim of this study is to compare two groups of children both practicing the freestyle swimming stroke. One group attended the Juklík swimming club from an early age and the second group attended swimming lessons provided through primary school. An integral part of this study was to compare the teaching methods, preparations and objectives used in the two models. Results of these observations are displayed in the form of graphs based on the results of an identical swimming test.

At the same time determine, whether was lifted memberships of modern pentathlonists (the number of clubs, the number of competitors). Methods: Comparison method for comparing performance results, the method of mathematical and statistical for processing of obtained data. Results: We found, that the swimming performance in modern pentathlon, due to this cooperation, in the surveyed category U15, has not improved. Furthermore, we found, that the influence of this cooperation between the Czech Union of Modern Pentathlon and chosen Swimming clubs, has lifted the number of competitors, who actively participates in the modern pentathlon competitions.

Analysis of stroking movements of crawl technique in persons with visual disabilities
Hájíček, Marek ; Jurák, Daniel (advisor) ; Zenáhlík, Aleš (referee)
Title: Analysis of stroking movements of crawl technique in persons with visual disabilities. Complained by: Bc. Marek Hájíček Supervisor: Mgr. Daniel Jurák Ph.D. Objectives: The aim of the study was to determine differencees among swimming technique of visually impaired swimmers and fully health swimmers. Methods: To assess the technique of the crawl swimming method, we used a 50 m swimming test, which we recorded and subsequently evaluated using the SmartPaddles technology and application. Results: Based on the results, we can say that the biggest differences in the technique of VI and fully health swimmers we recorded in the number of strokes per minute, in the total speed and in the execution of the stroke curve with the right and left hand. Fully health swimmer evenly distributed muscle strength between the two arms, while a swimmer with a VI had trouble maintaining muscle strength throughout the stroking movement. We have found that for visually impaired swimmers, it is necessary to devote more time to training and mastering swimming techniques than for healthy swimmers. Keywords Swimming technique, crawl, visual impaired, SmartPaddles.
