Negative numbers in contemporary primary school mathematics
Skálová, Tereza ; Slezáková, Jana (advisor) ; Jirotková, Darina (referee)
The aim of this thesis is to deal with teaching of negative numbers in mathematics in lower primary school. The thesis brings an overview of exercises related to negative numbers, which are available in textbooks dedicated to lower and upper primary school. Main part of the thesis is devoted to three different experiments - pupils experiment, teaching experiment and parlour game. The pupils experiment analysis the successes and troubles of pupils attending 4th and 5th class when filling out the worksheets focused on various models of negative numbers. Furthermore, the teaching experiment based on a questionnaire survey describes comments of lower and upper primary school teachers in regards to implementation and usefulness of negative numbers. Parlour game experiment demonstrates the ability of pupils to grasp mathematical phenomenon by playing a game. Key words: additive operations with negative numbers experiment models of negative number: thermometer, floor, surface environment Stepping environment Stairs word problems board game negative numbers

Detection of Signs of Fatigue in Functional Tests in Healthy Population by OpenPose
Skalová, Tereza ; Nováková, Tereza (advisor) ; Šorfová, Monika (referee)
Title: Detection of Signs of Fatigue in Functional Tests in Healthy Population by OpenPose Objectives: The aim of this study is if the OpenPose system can detect changes in range of motion and unwanted movements of other segments in repetitive a full arm abduction test with weight and a single leg stance based on comparation of changes in angles and relative distances between first and last seconds of the movement. Methods: This pilot study was dedicated to healthy people between 18 and 65 years. A video recording was made within an intervention while subjects were doing a full arm abduction test with weight and a single leg stance until the maximum endurance. Videorecording was processed by the OpenPose software which detects human movements base on algorithm without using a physical markers. Key point combinations (markers) were defined to obtain information about changes in movement and posture (angles, relative distances). Basic statistical measurements were done and compared between first and last seconds of the movement. Temporospatial data were collected to reach the results. Results: Almost all differences in key point combinations to detect arm abduction movement were evaluated as statistically significant. Changes in single leg stance were usually evaluated as not statistically...
