Effect of sowing rate on the yield formation and quality of spelt wheat in organic farming
Myšková, Radka ; Capouchová, Ivana (advisor) ; Petr, Petr (referee)
The area of cultivated land used for organic farming expands every year, as does consumer demand for organic food. Organic farming is a system of land cultivation without chemical inputs, because chemicals can have a negative impact on the environment, human health as well as health of farm animals. An important part of organic farming are also various sowing methods based on the alternation of a broad range of different crops. Dinkel wheat (Triticum spelta, also known as spelt or hulled wheat), is ideally suited for this system, as it is less demanding in terms of external environmental conditions than bread wheat (Triticum aestivum, also known as common wheat.
The aim of the bachelor thesis was to gain insight about the impact of the seeding rate on the yield and the consequent profit from dinkel wheat in organic farming. A second objective was to evaluate any differences in the values of selected quality indicators of grain, depending on the seed rate. Finally, on the basis of the obtained results, to choose the seeding rate which proved to be ideal in given conditions.
The results of our experiments with selected genotypes of spring and winter dinkel wheat and control varieties of bread wheat sown in different seeding rates (100, 200, 300, 400 and 500 germinable seeds per m2) in the organic way of farming in the Research Station in Prague - Uhříněves show that the spring genotypes of dinkel wheat had a peak of offsetting almost a month later, in comparison with the control variety of spring bread wheat. Winter genotypes of dinkel wheat had this peak of offsetting approximately two weeks later than the control variety of winter bread wheat.
Both dinkel wheat and the control variety of bread wheat from low seeding rates (1.0 and 2.0 million of germinable seeds/ha) offset more as expected, and simultaneously achieved a higher average weight of dry aboveground biomass and biomass of the roots per plant than plants of high seeding rates (4.0 and especially 5.0 million of germinable seeds/ha).
The evaluated genotypes of dinkel wheat compared to the control varieties of bread wheat were generally characterized by intense offsetting, higher weight of dry aboveground biomass, and especially higher weight of dry matter of roots per plant.
Achieved yields were negatively influenced by the course of weather conditions, especially by the drought throughout most of the vegetation period in 2015 - spring varieties of wheat, however, were affected by the drought far more than winter wheat.
Based on the resulting yields, we can say that in our experiment the spring genotypes of dinkel wheat had the highest yields in the seeding rate of 4.0 million of germinable seeds/ha, for winter dinkel wheat the best seeding rate was 3.0 million of germinable seeds/ha (however, variety of Rubiota had a high yield already with the seeding rate of 2.0 million of germinable seeds/ha). To specify the information, it is needed to obtain results from more years.
From the evaluated genotypes, the yield of white spring dinkel wheat slightly outperformed the control variety of bread wheat Granny and in particular the second genotype of dinkel wheat, T. spelta KEW. In the case of winter varieties, the yield of dinkel wheat Alkor outperformed the second variety of winter dinkel wheat Rubiota as well as the control variety of bread wheat Penalta.
The evaluation of qualitative parameters showed that genotypes of dinkel wheat outperformed the control varieties of bread wheat, especially in the content of N-substances and wet gluten content in grain dry matter. Both spring genotypes of dinkel wheat also achieved very good results in the Zeleny sedimentation test - both exceeded the minimum value required from wheat for bakeries (30 ml). Also winter varieties of dinkel wheat Rubiota exceeded this limit. The number of decrease was high in the evaluated varieties of winter wheat, while spring wheat was negatively affected by sprouting due to the rainy weather just before the harvest. The level of seeding rate had no effect on the values of qualitative indicators.

Effect of fertilization of permanent grassland on the substrate biogas yield
Stibůrek, Jakub ; Fuksa, Pavel (advisor) ; Jiří, Jiří (referee)
The aim of this study was to extend knowledge about the influence of permanent grassland fertilization on the yield and the quality of biogas.
During the years 2013 and 2014 three levels of fertilization (non fertilized control, N50PK, N200PK) were tested. Samples were taken from the experiment site Černíkovice, Benešov region. For anaerobic digestion, a 40 day mesophilic conditions batch test was chosen.
A statistically significant decrease of substrate biogas yield (SBY) and area biogas yield (ABY) with higher doses of fertilizers occurred between non fertilized control (575.4 ml/g; 3332.4 m3/ha) and N200PK variant (460.5 ml/g; 2605.7 m3/ha) in 2013. The only statistically significant differences in the quality of biogas were found during the first day of anaerobic digestion, when the highest doses of fertilizers caused higher concentration of methane (33.2 %) compared to control variant (22.6 %).
Application of fertilizers had no significant effect on SBY in 2014. Still, the highest SBY was obtained from the non fertilized control (762.7 ml/g) compared to N50PK (707.6 ml/g) and N200PK variant (732.8 ml/g). Furthermore, significant most of the ABY was obtained from the N50PK (2911.5 m3/ha) compared to the non fertilized control (2296.3 m3/ha). The only significant differences in biogas quality were found during the initial 7 days of the test. Most of the methane was contained in biogas from the non fertilized control (59.1 %), and least amount of the methane was found in the N50PK variant (57.9 %).
ABY is highly influenced by the yields of phytomass, which were negatively affected by the late first cut caused by unfavorable site conditions in 2013.
Cumulative biogas production showed that the most important part of anaerobic digestion was during the initial 14 days, which produced upwards of 80 % of total biogas yields in both years.

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.

Enzyme activity and molecular characterization of fungi in decaying wood
KONAROVSKÁ, Kristýna
Decomposing wood is necessary part of forest ecosystem. Wood is robust and hardly decomposable material. Some fungi can use enzymes to degrade lingocellulose. This bachelor thesis is concerned with these fungi and enzymes. Goal of this work was to describe factors affecting composition of fungal community in deadwood. Two different kinds of trees - beech and fir had been sampled from trunks and branches and ergosterol content, fungal biomass, activity of extracellular enzymes and fungal community composition were determined. Main watched property has been different source of samples coming from tree trunks (T) or branches (B) and from Silver fir (FWD) or European beech (CWD) thus forming 4 categories FWD-T, FWD-B, CWD-T and CWD-B. Analysis confirmed higher potential activity of enzymes and higher pH in samples taken from branches specifically endocellulose, exocellulose, endoxylanase, N-acetylglukosaminidase a -glukosidase. Ergosterol marker confirmed higher biomass content in branches. Ascomycet or Basidiomycet fungi content was not dependent on type of wood or its size. Enzyme activity and fungi biomass with lower pH confirms higher fungi enzymes content in branches in comparison to trunks. Presence of fungi influences substrate thanks to active metabolism. Higher biomass values were linked to faster branches colonization and their decomposition.

Evaluation of grain yield formation and state of health in winter wheat: line versus hybrid cultivar
MAGOČI, Jan
The aim of this thesis is the evaluation of grain yield formation and state of health of the line and hybrid wheat. For this target it was founded a one-year small-land experiment on the land of the Faculty of Agriculture of The University of South Bohemia in České Budějovice in September 2014. The experiment had 16 different variants in four repetitions, where the main factor was the different cultivar - Hybrid Hymack and line Tobak were sown at two different dates (early date 20th September, late date 29th October). In both of sowing dates, cultivars also differed in amount of seed quantity, where for Hymack it was 1,1 and 2,2 MKS/ha and for Tobak it was 3,5 and 4,2 MKS/ha. The last option was the stimulation by using the products from the company EGT and checking. During the vegetation, the number of plants per square meter, number of tillers and number of spikes were monitored and the state of health was evalueted. After the harvest were evalueted the grain yield, volume weight, HTZ and the number of grains per spike. The indicative measurement was made by the N - tester and a Sun Scan. The results achieved during the one-year small-land experiment show, that due to the influence of favorable year and high intensity of cultivation, a line cultivar Tobak achieved a higher yield (10,4 t/ha) compared to hybrid cultivar Hymack (10,4 t/ha) about 7 %. In the evaluated parameters the biggest difference was in HTZ, when Tobak had 47 grams and Hymack had 43,5 grams. This difference was the reason for higher yield of the line cultivar. Both of cultivars have achieved a better yield in the early sowing date and responded positively to the application of the growth stimulators. On the contrary, in the late date of sowing, cultivars reached a higher volume weight of the grain. During the growing season, the hybrid cultivar had better state of health and considerably higher tillering capability and the leaf area. The hybrid wheat's yield potential can be applied especially in unfavorable conditions such as drought or poor quality soil. At high intensity of cultivation supported by suitable climatic conditions, hybrid wheat hasn´t got an economic application in comparison with profitable line cultivars. The reason for this, is the high price of the seed and need for higher doses of nitrogen. The hybrid wheats are suitable for unfavorable growing regions with early sowing.

Charakteristika reprodukčních vlastností hřebců působících v inseminaci
BÚDOVÁ, Alena
One of the requirements for a successful insemination in horse breeding is the selection of quality stallions which produced ejaculate in enough quantities and of good quality. For this purpose were discovered methods of dealing with the evaluation of semen quality. In this dissertation was ejaculate evaluated by using an objective computerized method CASA, system SCA. Monitoring the quality of sperm was performed on 11 breeding stallions involved in artificial insemination fresh sperm in ZH Písek. 53 samples of ejaculate were evaluated. Volume, sperm concentration, total and progressive motility and sperm vitality were monitored. Volume of ejaculate was from 20 to 127.5 ml. Average values of sperm concentration for individual stallions were from 104.18 to 384.4 M/ml. Average values of total motility were moving by interval from 51.23 to 89.54 %. Average progressive motility was move from 12.99 to 47.12 %. At sperm vitality were discovered average results from 35.16 to 71.21 %. The average value of individual stallions was identical to the Decree of the Ministry of Agriculture, which sets minimum requirements for quality indicators for short-term preservation of semen. Also the quality of the semen of stallions was compared by age. The first group was made by stallions to 10 years old and the second group were older stallions. It was found that the younger stallions to 10 years had higher semen volume and greater sperm concentration. Stallions older over 10 years had higher levels of total and progressive motility and sperm vitality. Next ejaculate quality was evaluate by the time interval between samples. Regular taken from stallions is doing better ejaculate quality but the time interval between samples is important. The best values were found in samples with interval between the sampling 4 or more days. The worst quality of sperm was in the samples with the interval between 1-2 days.

Fyzikální vlastnosti medů
Slováček, Robin
The bachelor thesis is focused on the physical and rheological properties of honeys and influences on these properties. Physical properties of honeys are very different depending on chemical compositon on honey, sources of honey, climatic and geographic conditions. Crystallization of honey depends on the content of glucose and frucose. Nectar honey crystallize more rapidly than honeydew honey, because nectar honey has got a higher amount of glucose. The density of honeydew honeys is higher then nectar honey. The higher density of honey have a honeydew honeys, it is about a minerals. The colour of honeys depends on botanic origin, processing method and lenght of storage. Nectar honeys are lighter than honeydew honeys. Electrical conductivity is very important feature, because this feature we can find out the botanic origin of honey. Honeydew honeys have a higher electric conductivity, because they have got a larger amout of minerals. Rheological properties of honeys depends on composition of sugar and botanic origin.Viscosity is a reological properties of honeys which dicreases with increasing temperature.

Influence of wood structure on wood properties of tropical species
Baar, Jan
The presented thesis is focused on aesthetical and acoustic properties of tropical wood. The discussed tropical species are utilized in Europe mainly for their unusual appearance and colour in joinery and furniture production. The irreplacable acoustic properties like low internal friction predestine specific species for production of musical instruments. The colour of six selected tropical species - jatoba (Hymenea courbaril L.), massaranduba (Manilkara bidentata A. Chev.), muiracatiara (Astronium graveolens Jacq.), angelim amargoso (Vatairea spp.), angelim pedra (Hymenolobium spp.) and angelim vermelho (Dinizia excelsa Ducke) - were analyzed and expressed in CIEL*a*b* colour space. Subsequently the samples were exposed to artificial sunlight and the light-induced discolouration rate and progress was evaluated. The colour change was rapid in zhe first hours of exposure and all species showed a similar trend in lightness (L*) change - initial darkening replaced by gradual fading. The change in chromatic parameters (a* and b*) change was specific for individual species and probably related to the chemical composition of the extractives. The overall discolouration of lighter coloured wood samples is more distinctive. The extractive content of tropical species is usually high and determines wood colour. The wood of African Padauk (Pterocarpus soyauxii Taub) and Jatoba (Hymenaea courbaril L.) was extracted in a mixture of methanol, water and acetone. The total extractives and total phenolic content was measured. Extractive content was related to colour parameters and above all to lightness in both species. The increase in extractive content leads to a lighter and more yellow colouration of Jatoba wood while African Padauk was darker with a higher amount of extractives. In Jatoba, a positive correlation was found between extractive content and the rate of discolouration. The extractives are responsible for intensive discolouration of tropical woods in contrast to light coloured woods from the temperate zone, where the yellowing is primarily caused by lignin photodegradation. The sound velocity was measured by ultrasound and resonance longitudinal method in heartwood of doussie (Afzelia bipindensis), merbau (Intsia bijuga), wengé (Millettia stuhlmannii Taub.), muiracatiara (Astronium graveolens Jacq.) and zebrano (Microberlinia brazzavillensis). The sound velocity was not related to the density in any case. Although anatomical structural characteristics as fiber length or ray ratio positively influenced it. With longer fibers and slender rays the sound velocity increased. Other acoustic properties like dynamic young modulus of elasticity, specific modulus of elasticity, internal friction and acoustic conversion efficiency (ACE) were determined and were related to measured anatomical features. The differences in composition of wood tissue of individual species were the main source of departure between the assessed relationships. The wood with longer fibers and lower frequency of rays reached lower values of internal friction. The stiffness of wood characterized by the dynamic modulus of elasticity was correlated with fiber and ray tissue. A higher volume of fibers influenced the stiffness positively, while ray volume had the opposite effect on stiffness. Positive effects of fiber length and ray ratio were found for dynamic modulus of elasticity and for acoustic conversion efficiency as well. Both values increased with longer fibers and higher ray ratio. The sound velocity is the basis of some nondestructive techniques for determination of wood mechanical properties. The comparison of density and three dynamic moduli of elasticity (longitudinal and flexural resonance method and ultrasound method) in prediction of mechanical properties was carried out. The density was evaluated as a poor predictor when the samples are not straight-grained and defect free. The interlocked grain often occurred in tropical species and its presence influences the mechanical properties of wood but not wood density. The dynamic moduli of elasticity showed strong correlation with the static modulus of elasticity. Among nondestructive techniques, the weakest correlation was found for the ultrasound method, which is probably partially explained by different measuring mechanism. The prediction of the modulus of rupture is less accurate when the dynamic modulus of elasticity is compared with the static modulus of elasticity; however, it was still good in comparison with the density model.

Motivace, hodnocení a odměňování zaměstnanců zákaznického servisu
Schovancová, Leona
This work focuses on very topical issue, and that is motivation, evaluation and remuneration of employees in customer service. All three areas are closely linked, and only their mutual optimization and compliance can increase efficiency and productivity in customer service. It is a very specific area in which most employees not only care about existing customers, but gain new customers, provide information, handle claims and complaints and they are the gateway for each company. Customer Service is demanding in both, quantitatively and qualitatively to human resources. Businesses try to find a reasonable balance between the cost of human resources and their further education and the required power and goal fulfillment. As in the care and sales, good human resources are of the highest importance. It is not enough just to hire good people, they must be further developed educated and coached. It is necessary to focus on their motivation, it is not always possible to motivate each employee in the customer service individually, rather their preference and needs should be determined and those should be satisfied. Most employees prefer clear and objective assessment in connection with a transparent system of remuneration. It should also be a business objective. Sales are more and more important activity in customer service and it is no longer sufficient just to take care of existing customers. It is necessary to develop retention measures, and especially focus on the acquisition and re-acquisition activities. Success is critical for motivation and quality of staff. The thesis is therefore focused on identifying ways to optimize human resources management, especially in the areas of evaluation and remuneration so as to achieve even higher productivity and to fulfill sales plans. Based on the found strengths and weaknesses in employee satisfaction surveys with regard to one of the strategic objectives of the RWE Group, which is to increase market share in electricity, this means the need to increase sales, there has been proposed modification of the current system for evaluating employees' customer centers with a direct impact on remuneration. Modified system of evaluation of service employees will be more motivating, because overreaching of sales plan will be the possibility to receive up to 50 % more of variable wage component. Newly, evaluated will not be only sales figures, but the effort to sell as well. Monitored customer centers are in different locations and the CR has different regional conditions, which are mainly the different practices and different people and activities of competitors. It is important to recognize and motivate employees to implement the menus, although they are not always used. Evaluation protocol for internal supervision was modified significantly; greater significance was given to the criteria that directly support the current performance targets. Significant changes were also seen in the evaluation protocol that includes not only an overview of evaluation results, but there is listed the number of sales made, the amount of bonuses received for the sale, to calculate the total variable part of total wages and salaries to be paid. In the area of remuneration for service staff proposed a change of the ratio of fixed and variable components of wages from the current 85 : 15 to 80 : 20. Optimized system of remuneration consists of salary, bonuses and rewards for sales and rewards for sales in sales contests. Newly was developed a system of pay commission sales in customer centers. The proposed salary is fixed at the minimum wage for the group work in the CR, it is 8900 CZK. Now the average fixed salary of vendors is 15 660 CZK. Employees will have a greater portion of variable pay. The largest share of the variable component will be bonuses for the number of concluded contracts. Due to higher incentive bonus payment system for contracts, it is designed progressively. Newly, there is no upper limit for wages. Part of the variable components of wages will continue to be paid for customer-oriented access and correct communication; the evaluation will be conducted according to the newly proposed system for sellers' evaluation. Dissertation on a specific department analyzes current situation in the customer service in the area of motivation, evaluation and remuneration. It identifies strengths and weaknesses and proposes solutions for eliminating of weaknesses. Not always, however, the interests of employees and the company are in compliance, the work focuses on optimizing of these areas especially in terms of achieving its goals, it means from the viewpoint of a business.
