Plants traditionally used in the Czech Republic for their antimicrobial properties: An overview and comparison with scientific studies
Ježková, Pavlína ; Nový, Pavel (advisor) ; Houdková, Markéta (referee)
The use of plants in medicine and folk medicine is probably as old as humanity itself. Medicinal plants have accompanied human throughout the stages of its historical development and herbs were the first medicines which human met. Healing herbs were the most accessible and often only therapeutic agent.
In the first part of the thesis, the information about the history of medicinal plants, natural method of therapy, phytotherapy, biologically active substances of plant and about antimicrobial agents are summarized. Some specific cases of plants with antimicrobial activity are also listed.
The second part presents data obtained by comparing data on the traditional use of plants for their antimicrobial activity in folk medicine to scientific data available from the Web of Science database. The traditional use of plants was investigated according to data from the most comprehensive Czech herbarium of medicinal plants from Jiří Janča and Josef Antonín Zentrich. From a total of 363 plants, 207 species whith presumable antimicrobial activity were selected from the herbarium,. For these plants were subsequently searched and evaluated all records from scientific databases mentioning their antimicrobial activity.Sbsequently, all records on these species mentioning their antimicrobial activity were searched on the scientific database and evaluated.
After the comparison and evaluation of the data gathered about the initial 207 species, 31 plants, which should exhibit antimicrobial effects according to the aforementioned herbals but scientific records are confirmed unsatisfactorily or not at all, were selected. This group of plants can serve as the basis for future research to confirm or refute their antimicrobial activity.

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.
2
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.

Rain impact on FSO link attenuation based on theory and measurement
Brázda, V. ; Schejbal, V. ; Fišer, Ondřej
The FSO link becomes a usual mean of modern wireless communications. But it suffers from atmospheric particles causing attenuation. That´s why this random attenuation must be carefully considered by the FSO link design. As it is known the most serious atmospheric phenomenon is fog, and low cloudiness. But the rain attenuation (night mare of mm wave links) is not negligible on optical links, too. In this contribution we focus on rain attenuation from theoretical as well as experimental point of view. Statistics and rain event analysis are shown. There is an overview and a comparison of several formulas for rain attenuation derived from DSD or rain rate. Rain is not the worst phenomena for the transmission but we can’t neglect its influence on FSO. Only full understanding of influence of real atmosphere can lead to solution of a high availability of FSO systems.

Microalgal Growth Problem for the Photosynthetitc Factory and its Optimization: An Overview and Further Analysis
Čelikovský, Sergej
The overview of the micro-algal growth problem for the photosynthetic factory and its optimal control solution is presented here. First, the model description and its properties like Haldan steady state dynamics, light integration property and the forward invariance of the set of biologically well-de ned states are described. This shows that the model meets basic experimentally based requirements. Further, its optimal control problem is formulated and solved analytically for the one dimensional singular perturbation based reduction. Properties of the optimal control for the reduced model are discussed and compared with some experimental observations. Among them, the general biotechnological paradigm that on large time intervals the optimal solution is, in certain sense, almost constant, is substantiated. As a new original result of this paper, the explicit solvable di erentiable equation for the unsaturated part of the optimal control is derived.

Measures after real akcident on impregnation line (associated with the release of hot impregnating oil)
KUKLOVÁ, Radka
In his work focus on what risks there is a risk to people and the environment in wood preservatives. My thesis concerns specifically one company, which became a serious accident some time ago. It also entails my goals. The objectives of the work are the analysis and risk evaluation technology of boiler impregnation impregnation line no 4 and the assessment of the safety of these chemical technology operations and further evaluation of the sufficiency of the technological measures imposed on impregnating line after the last crash. In the theoretical part is described by the company has, therefore, impregnation of Bristol in particular about what kind of company it is, what it actually produced, where it is situated and its history. In the next part of the theoretical risks described are, what the risk is, what are the species and what is covered. In addition, here I deal with dangerous substances, which are handled in this company. I present here, as they are dangerous and in what concentrations there are and how they are stored. Last but not least, the theoretical part of my work deals with the analysis of the resulting handling chemical substances. The obligations of the State laws No. 262/2006 SB., labour code, Regulation of the Government No. 361/2007 Sb. laying down the conditions for the protection of health at work, Act No. 258/2000 Coll., on the protection of public health and amendment to certain related laws, Decree No. 432/2003 Coll., laying down the conditions for the classification of the work into categories, limit values for indicators of biological exposure tests, the conditions of collection of biological material for the implementation of biological exposure tests and requirements for the reporting of work with asbestos and biological agents. In the next part of this work deal with the wood, its properties, parasites and the possibilities of the impregnation and in the last part I was just an accident and its aftermath. The theoretical part is in the summary is processed so that the reader after reading an overview of the status of the company, what the company does, what kind of wood is here and as aerosol inhalants. Furthermore, in order to have an overview of what hazardous substances are handled here, as they are dangerous and how many are stored here. Furthermore, according to which the laws and ordinances are obliged to follow and what actually happened here, or why it was needed to handle the job. The next part of this work, the research part, described the methodology of research, which provides the procedure by which was obtained the data needed for part of the score. Method of investigation, to obtain the necessary information, was implemented by means of a risk analysis, namely the method of What happens when (What-If Analysis). This method is based on the issues of the different situations that might happen in the circumstances and to research whether or not to become, and what is the likelihood. Chosen were such questions that touch the impregnation of boiler No. 4 and any accidents that might happen on this boiler. These questions were also chosen on the basis of previous crash. Persons who respond to questions, were selected by function and expertise. A total of 23 issues. Results section contains the results of the risk analysis. Found results are given in the form of tables that show the questions and answers. Below are the individual parts of the analysis described here, where it is stated what they represent and what each question and answer it results in conclusions. After a total evaluation of the research, based on observed data, it can be concluded that the protective measures in the company after the crash was increased to an acceptable degree. Protective measures, of course, has been here before, but due to the fact that the crash occurred so was not sufficient. But the subsequent measures of protection, which was introduced after the crash, they are sufficient.
