Standards of periradicular therapy under CT control of the department of imaging in the Hospital Jihlava
DOLEŽALOVÁ, Jarmila
The topic I have chosen for my bachelor thesis is treatment of backaches. I have focused on treatment options of radicular pains. The thesis is divided into theoretical and practical part. The first part focuses on description of spinal anatomy, neuroanatomy and spine functions. Backaches belong to the most common diagnosis of not only general practitioners but also specialists. Almost everyone, at least once in their life, visits a doctor with pains related to their back. There are a lot of factors involved in the rise of backaches. The permanently developing non-vascular part of the intervention radiology helps, thanks to its therapeutic methods, with backache treatments where conservative treatment procedure is inefficient for a patient. Current medicine offers a whole range of minimally invasive treatment algorithms. One of the possible minimally invasive treatment procedures in the area of cervical and lumbar segment of the spine is a periradicular local injection. The medical treatment into intervertebral area surrounding the spinal nerve is intended and performed under regulated CT control in sterile conditions. Another newer minimally invasive method is oxygen ozone therapy. This method exploits biochemical propertiesof ozone. Minimally invasive treatment methods are being successfully carried out at the ward of imaging methods in Jihlava's hospital. The difference between the two methods presented is the contents of the curative mixture. Both methods, closely described in the theoretical part, are accessible for the patient as well as well tolerated with minimal negative reactions related to the treatment. The conclusion of the theoretical part contains the description of the indication for an examination, the contents of a particular curative mixture, the information related to contraindication of this treatment as well as possible complications and also the description of therapeutic effects it has on a patient. It includes evaluation methods and comparison from time and financial point of view and an opinion of a radiology assistant. The practical part includes a detailed procedure and performance of medical treatment where the output shows the process of local radiology standards of individual methods designed for the needs of the ward of imaging methods in Jihlava's hospital. The processed standard will improve awareness from other hospital wards about this medical treatment. Subsequently I am comparing both methods which was the given aim of this thesis. The methodology of this assignment includes the evaluation of achieved results. The observed database was a group of patients that underwent a curative therapy in 2011 to 2013. The database includes the medical treatment, the age and gender of a patient and the treated part of the spine. It also shows the overall amount of treatments divided into individual years. The final assessment was based on a total number of 668 patients and is shown in graphs and charts. The explorative question of this assignment whether the number of patients of the minimally invasive therapy will grow while their age will decrease has proved to be true. These are some of the results shown in the graphs: the overall number of patients in the observed time period of 2011 2013 grows, however in 2013 we can notice the increasing number of female patients as opposed to the decreasing number of male patients in the area of lumber spine. Dividing patients into age categories shows that the number of patients increases up to the age group of 51 to 60 years of age, after that it decreases. The above mentioned age group formed more than 35 % of all patients. Minimally invasive medical treatments performed in the spine area improve the patient's life comfort and the positive healing effect makes their physical and mental condition as good as it was before.

Bayesian classification of digital images by web application
Talich, M. ; Böhm, O. ; Soukup, Lubomír
The contribution introduces web application for image classification that has been developed at the Research Institute of Geodesy, Topography and Cartography in the framework of grant project InGeoCalc (supported by Ministry of education of the Czech Republic). The web application is aimed to display, examine and classify digital image data. The data are expected to be obtained from Internet by means of Web Map Services (WMS) or from other sources (possibly non-registered). Image data from different sources can be combined and presented as composition of layers (coverage) with adjustable degrees of transparency. After gathering the data, Bayesian (supervised) classification is applied to distinguish separate regions in the image. User can choose between several classification methods and adjust pertinent parameters. Furthermore, several subsequent basic analytical tools are offered, namely computation of distances, areas or perimeters related to the classified regions, simple statistical summaries about classification results (e.g. distribution of classes, percentage of non-classified regions, etc.). The classification results and registration parameters can be saved for further use. The web application is based on common Internet standards (HTML, Javascript, SVG). The only requirement for running the application is an up-to-date Internet browser supporting SVG (Scalable Vector Graphics). Typical usage of the web application can involve land cover mapping based on satellite or aerial images. The application is available free of charge for any Internet user.

Experimental measurement of full-field strains in the vicinity of U-notch in ductile material
Jandejsek, Ivan ; Jiroušek, Ondřej ; Vavřík, Daniel
The paper deals with the measurement of full-field displacements and strains evolution in the vicinity of the U-notch in the flat high-ductile aluminum specimen during its loading. The full-field displacements are measured using Digital Image Correlation method in a set of vertices of a triangular mesh reflecting the presence of the stress concentrator. From the known displacements strain distribution is computed. The resulting strain field is compared with simultaneous strain gauge measurement. These strain gauges are located just in a few well-defined positions and serve for correction of a systematical error caused by rigid-body motion of the specimen during loading. The experimental results are used as referential for Finite Element simulation using the same triangular mesh.

The Role of Scientometric Criteria in the Formation of Budget and Qualification Growth at Pavol Jozef Šafárik University in Košice, the Slovak Republic
Černák, Juraj
Pavol Jozef Šafárik University in Košice, according to the number of its students (approx. 8,700), belongs to the group of smaller-size public universities in Slovakia. The major part of its budget income (approx. two thirds) comes from a direct state subsidy. The subsidy amount is defined by the Methodology of the Ministry of Education, Science, Research and Sport of the Slovak Republic that is modified yearly. This Methodology uses various input data that are related to research activities of a university, the results of the last complex evaluation, the amount of financial resources obtained from home grant agencies and from abroad, as well as the publications of lecturers, research staff and students of a university, etc. The amount of publications as a scientometric criterion was for the first time used in 2005 and since then its proportional representation has risen substantially and it represents a strong motivational aspect for universities in Slovakia. The number of publications also plays important role in the qualification growth of P. J. Šafárik University lecturers and research staff. The specific requirements as to the categories and numbers of publications to be met by a candidate for the habilitation (associate professor status) and inauguration (full professor status) are defined by several legislative documents and are further specified by the documents approved by the Scientific Board of the University. The qualification growth of lecturers is also important for the University as it has its influence on the amount of the direct state subsidy. The presentation will focus on the importance of the publication activities as one of the scientific criterion relevant to the research and scientific activities of the University and the methods of publication registration by the Ministry and the University, their strengths and weaknesses will be discussed.

Recovering of Company's Website
Lang, Michal ; Lohr, Václav (advisor) ; Martin, Martin (referee)
Summary
Small business operating in villages usually face the problem of lack of customers,
especially if they offer luxury products. The budget of such companies is often limited
and therefore they cannot afford an expensive advertising. The company website is one of the few
solutions that can get customers from outside the rural areas and thus create new business
opportunities and increase revenues of such companies. The main goal of the thesis is to attract
customers to a company website and thus help small businesses seeking customers in their difficult
situation. The theoretical part starts with the basics. It describes what systems are suitable for
different kind of web pages and the main part is focused on factors that influence an overall website
performance.
The second part shows how to achieve the stated goal on an example of a small joinery
company Atyp truhlářství Lang. The company is present on the Internet since April, 2009. The
work with a real website allows to compare results before and after the changes implementation.
The practical part starts with an analysis of the original website. It determines strengths and
weaknesses of the web and it provides suggestions for improvement. After this, the academic work
deals with the implementation of suitable factors. The final chapter evaluates the original and new
version of the site and represents how the made changes are reflected in the site traffic.
Keywords
Website design, SEO, on-page factors, off-page factors, CMS, Content Management
Systems, increase site traffic
Objectives and Methodology
The main objective of diploma thesis is to increase the website traffic, its attractiveness for
customers and thus help small companies located in rural areas to get new clients. The first part
helps to achieve the stated goal by dealing with aspects influencing the overall web page
performance and also provide basic knowledge related to the website design. Consequently, the
sub-objective of this part is an identification of factors that significantly affect the site traffic. The
second part aims to apply the gained knowledge on an example web page of small company Atyp
truhlářství which faces a problem of a lack of customers. It starts with the analysis of the original
website that shows its strangeness and weaknesses. This will provide an information about possible
improvements. The part of authors own work aims to implement suitable factors from the
theoretical part into the website design. The objective of the final part is to compare the changes
made with the original design and determine if the new site solution has really improved the number
of visits and its attractiveness for customer.

The essential information for the masters thesis elaboration were obtained from an analysis
of printed sources as professional books, journals, annual reports and online resources as well.
Statistical data reflecting the original website traffic were extracted from MySQL database. The
new data about number of visitors were already get in friendlier form of Google Analytics outputs.
In addition to that, author also discussed his academic work with website experts and used his own
knowledge acquired during the university studies of information technology.
Results and Conclusion
The website overall performance is greatly influenced by the system on which it operates.
For this reason, the literature review provides an overview about Content Management Systems
and Static Site Generators. There are explained differences between these two approaches to a website design and are given recommendations about what kind of pages are suitable for each
approach. The main part identifies 30 on-page and off-page factors that have a positive or negative
impact on the final website traffic.
The practical part consists an analysis of the examined site. It discovered the following
weaknesses. The positioning is very bad in Search Engine Result Page and it is almost impossible
to find the web without an exact knowledge of the company name or its location. Content can be
considered as extremely poor with overall 279 words only. There were also two technical issues.
The first caused a traffic data loss for the last five years due to exceeding 50MB of MySQL memory
limit. The second was related to plugins deployment that used up the whole PHP memory limit. It
resulted in WordPress strong unstability. The website speed test was disastrous. The small page
size of 762,52kB was loaded for 4,38 seconds. An acceptable result would be less than 2 seconds.
Concerning security, the site did not use secured protocol and the next risk could pose deployed
plugins that are frequent targets of hacker attacks. The used template was not mobile-friendly and
therefore it was difficult to browse the pages on mobile device. In addition to that the graphical
appearance had a low attracting power, it was not able to adequately impress the customers. The
site was visited by an average of 25 people a day in 2011. Furthermore, only 63% of visitors come
from the Czech Republic. Unfortunately, more actual data could not be obtained because of the
data loss. After considering of all mentioned issues above was proposed a complete website
recovery with an implementation of suitable factors from literature review.
The examined website is extremely static without a dynamic content and the frequency of
updates is relatively low. The web pages are managed by a technical contributor and it is the reason
why graphical user interface of CMS is not required. After evaluation of all previous technical,
speed and security issues was selected a static site generator for the website design.

The important chapter is represented by implementation of suitable factors that should as a complex lead to an increase of a site traffic. First important factor is a content. The original word
count of 279 words was improved to 1809 words which is 7 times more than in the past. Before
writing the articles, an analysis of relevant terms were made. Those terms are included across the
web content. The new articles are meaningful and they provide product details and customer
reviews. Moreover, the content is structured, there are 9 unordered lists included and main titles
are differentiated by importance. Each page has internal links to other subpages. The text clarity
and an inclusion of relevant terms are equal to a better rank of a page. The number of images has
decreased from 112 original images to selected 42 images on the new website. This is because of
a very bad image quality of most old pictures. The high quality images can cause customer interest
for the product, higher time on site and lower bounce rate. Meta descriptions were implemented
individually for each web page with regard to the page content. The new website was accepted by
a certification authority (CA) and the unsecured Hypertext Transfer Protocol was replaced by
Secured Hypertext Transfer Protocol (HTTPS). It means the site is trustable and secure for
browsing. There are no plugins used and therefore an attack risk is much lower. The template was
tested on 17 screen resolutions. All tests were successful and the site is fully responsive. Almost
33% of customers use some mobile device to browse a web. The current web eliminates the loss
of visitors coming from mobile devices. Furthermore, Google officially announced that secured
and responsive websites get priority. The site speed test had two rounds. The first test can be
considered as very good. The page load time was 842ms and overall page size was 1.1.MB.
Nevertheless, after the compression of large files the site became even faster. The page size
decreased by 30% to 771,6kB and the final load time speed up by 31% to 580ms. Currently, the
website is faster than 96% of all tested domains which is a perfect score. The adjusted site speed is
7,5 times faster than the original speed. No flash, advertisement or other disruptive elements are
available on the web. The web page is newly available on Google+, Pinterest and Twitter. These
factors are able to boost direct page traffic. The design is clean and simple just to avoid leaving
customers confused. The readability is also very good. Combination of black/blue text on the white
background or white text on the black/blue background doesnt cause any readability issues. Social
buttons and a quick company contact is present on each page in header and footer section. Another
change was made in traffic measurement. The website started to use Google Analytics for tracking
visitors. The actual traffic data are more accurate and the possibility of data loss is reduced.
The main goal of diploma thesis was to improve the website traffic. The web page was
measured from 01.12.2015 to 29.02.2016. The average site traffic was 23,0 visits a day in
December 2015. This number reflects the original site traffic which was around 25 visits a day with
a decrease of 8%. The biggest change in traffic development was found between 08.01.2016 to
13.01.2016 when the average site traffic was 77,2 visits a day. Those changes are explained by an
influence of social media. Author has written a post about Atyp truhlářství on Facebook on 8th
January 2016. The post was shared by 8 people and it attracted many people to visit the website.
4
From January 14th to the end of the month, the average daily traffic was 32,3 visits. The last month
was noted slightly higher traffic of 32,6 visits a day. The comparison of data from December 2015
and from February 2016 shows a visible increase in number of visits in February 2016 where the
traffic was higher by 41,7%. There is a positive increasing trend in a number of visits since the
beginning of December 2015. Moreover, majority of visitors 81,3% come from the Czech Republic
and it is a better result than by the original web pages with 62% only.
The recovery of a small joinery website atyptruhlarstvi.cz was successful. It improved the
website traffic and many other aspects as content, speed, security, responsiveness, social media etc.
The web design itself and implemented factors can be considered as crucial elements that influence
the final number of visits. For this reason, the made changes on a web page can really help small
business in rural areas to get new customers. There were also identified factors that affect an overall
website performance with an emphasis on a positive site traffic development. An overview about
different website design approaches is provided as well.
