Conduction of low frequency current - TENS - through human tissues
Černíková, Kateřina ; Malá, Jitka (advisor) ; Pánek, David (referee)
Thesis title: Conduction of low frequency current - TENS - through human tissues Name: Kateřina Černíková The aim of the thesis: The aim of this study is to determine, whether applying low frequency TENS cause the conduction of electrical potential to muscle groups outlaying from the point of irritation. And if the frequency has an influence on the conduction. Subjects and Methods: Application of low-frequency current, namely transcutaneous electrical neurostimulation, in the frequencies of 45 Hz, 121 Hz and 235 Hz - on the paravertebral muscles, on the left side of the body. It's a pilot study involving 6 probands (1 man, 5 women) aged 20-30 years. Electrical activity was measured by surface electromyography. Spectral analysis carried out in the Master MyoResearch XP program was used to evaluate the measured data. Results are graphed for clarity. Results: It was confirmed that the condution of electrical potential in the organism exceeds the site of stimulated muscle. However, these are a very low values to be used in clinical practice. This conduction varies according to the applied frequency. With higher frequencies, electrical current gets more to outlying muscle groups. Furthermore, it was found that the frequency of applied current doesn't appears in the used frequency, but in its multiples....

What is the effect of highway proximity on house prices in the Czech Republic?
Černíková, Kateřina ; Lahvička, Jiří (advisor) ; Mirvald, Michal (referee)
This thesis investigates the effect of highway proximity in relation to house prices. Based on theory it's assumed, that houses located near highway may be more expensive due to better accessibility to different cities. For this analysis the hedonic price model has been used on 1.055 houses located in Kraj Vysočina and in the Benešov district. Those houses had been offered on sreality.cz webpage in 2012. It has been found, that every extra minute necessary for reaching highway ramp decreases the house value for 0, 4 %, although this can be claimed for houses located farther than 1km from the highway only. If the house is located within 0 - 400 meters (straight-line distance) the price (ceteris paribus) is lower in tens of percents (c. 60%). This is most likely caused by negative externalities produced by highway. In contrast to previous studies, it hasn't been confirmed any price premium for houses located far away from highway.
