Mobile Phone Location Data: Possibilities of Use in Geographical Research
Novák, Jakub
Charles University in Prague Faculty of Science Department of Social Geography and Regional Development Jakub Novák MOBILE PHONE LOCATION DATA: POSSIBILITIES OF USE IN GEOGRAPHICAL RESEARCH Synopsis of PhD Thesis Prague 2010 Supervisor: Assoc. Prof. Zdeněk Čermák Jakub Novák Synopsis of PhD Thesis 1 Jakub Novák Synopsis of PhD Thesis 2 INTRODUCTION Spatial mobility of world population has been unbelievably changing during the last decades. People from poor countries are moving thousands of kilometers to developed countries with the vision of material prosperity. Airplanes transport thousands of people in hours to places, where people had travelled much longer recently. Similarly, also an ordinary weekday is for the majority of population connected with relatively long moves between different places of daily activities. Traveling between home, work, kindergartens and schools, shops and leisure activities takes the significant part of our daytime. To capture the measureless amount of particular human creatures in their day-to-day moves through time and space seems to be almost impossible. In fact, it is not so unrealistic. Currently, we are surrounded by a number of electronic devices, which dispose with information about its location or record moving objects in their vicinity. Mobile phone is one of such...

Handwritten character clustering
Novák, Jiří ; Mrázová, Iveta (referee) ; Štanclová, Jana (advisor)
This diploma thesis deals with comparision of di erent method for handwritten character recognition. A goal is analysis of this problem, comparision of several pattern classi cation methods and methods for feature extraction. In details there are discussed three algorithms for data clustering. These algorithms are following: k-means clustering, k-neighbors algorithm and algorithm of iterative optimalization. Another three algorithms are using neural networks. These are algorithm of competition learning, back propagation algorithm and Kohonen selforganising maps. These method are tested and compared according to percentage of correctly recognized characters. A summary of our own results is included.

Possibilities of preoperative determination of local extent of prostate cancer
Záleský, Miroslav ; Urban, Michael (advisor) ; Jarolím, Ladislav (referee) ; Novák, Jaroslav (referee) ; Pacík, Dalibor (referee)
Author analyses results of methods of preoperative local staging of prostate cancer (digital rectal examination -DRE, prostate biopsy, statistical predictive nomograms etc.) Further he analyses results of imaging methods (CT, MRI, ultrasound and all of his modification- Doppler imaging, harmonic imaging, 3D reconstruction contrast enhancement).

Problems of renal tumours in patiens with terminal stadium of renal failure
Ürge, Tomáš ; Hora, Milan (advisor) ; Novák, Jaroslav (referee) ; Zachoval, Roman (referee) ; Morávek, Petr (referee)
Objective: Risk of renal carcinoma is minimal 10 x higher in group of patients in terminal stadium of renal failure (end stage kidney disease - ESKD). We have only some information about chromosomal changes in renal tubules, from which rise renal carcinoma, and about pathogenesis of renal carcinoma, which seems to be different from carcinoma in common population. Aim of the study: In clinical part we valorize characteristic signs of renal carcinoma in ESKD by using of statistic methods. In experimental part we can explain pathogenesis of this carcinoma by analysis of selective chromosomal aberations. Material, methods: In 2000 - 2007 were 184 patients with ESKD in care of transplant centre and nephrologic ambulation of Faculty hospital Plze_. In 15 patients we diagnose renal carcinoma. In this group we valorize: age, gender, causation of renal failure and dialysis duration. Age, gender and type of renal carcinoma we confront with carcinoma in common population. In experimental part we valorize numerical aberations in chromosome 7, 17 and Y of tubular epithelium using fluorescent hybridization in situ (FISH). Results: We have 15 patients in average age 55.7 ± 11.5 years, long of during dialyzation was 78 ± 54 months. We do not find dependence between causation of renal failure and genesis of renal...

Source of Information and Nursery Schools
Levá, Zuzana ; Fialová, Irena (advisor) ; Novák, Jaroslav (referee)
This bachelor work is focused on utilization of information resources in the kindergarten teacher's work. The theory defines information literacy and information resources, particularly digital resources. Practical part of the work deals with and describes various internet web portals dedicated to the kindergarten teachers and parents of the children. Using the question-form I have been collecting data about the information literacy of the kindergarten teachers and the way they use PCs and the internet in their daily work. Putting pieces together I propose the creation of complex web portal, which would be accessible not only for teachers and students of pre-school pedagogy but also for the parents of the children.

Immunohistochemical examination of microvascular density can be an additional prognostic factor in patients with superficial urinary bladder carcinoma, nevertheless, more extensive studies need to be carried out. Maximal microvascular density correlated with a recurrence free interval and in a case of bigger group of patients could be statistically significant. The statistical correlation between MVD and a nuclear p53 accumulation is that significant that we assume the p53 importance in the angiogenesis regulation of superficial urinary bladder carcinoma. The p53 positivity in non-tumor mucosa of urinary bladder in patients with superficial bladder cancer correlates with higher risk of tumor recurrence. According to our results the reason of urinary bladder carcinoma multifocality is genetic instability present in the whole urothelium at the time of tumor diagnosis. The PAX5 gene expression is a frequent finding in superficial transitional cell carcinoma of the bladder. From the prognostic point of view, high levels of PAX5 expression seem to be connected with higher recurrence and progression rates. The extent of lamina propria invasion seems to be a clinically relevant prognostic factor for progression of T1 bladder transitional cell carcinoma. Finding T1b tumor is connected with the risk of understaging....
