Darbo „Studijų kokybės vertinimas nuotolinio mokymosi sistemose“ tikslas – sukurti įrankį, kurio pagalba būtų galima nustatyti studijų kokybę nuotolinio mokymosi sistemoje. Pagrindiniai šio darbo uždaviniai yra orientuoti į darbo tikslą. Šiame darbe aprašytas, realizuotas ir į Moodle NMA įdiegtas Statistikos modulis, kurio pagalba galima nustatyti, ar yra ryšys tarp studento pažymio ir apsilankymų skaičiaus kurso medžiagoje. Pritaikytas statistinis metodas - koreliacijos koeficiento skaičiavimo metodas. Darbas inovatyvus tuo, kad tokio pobūdžio modulis sudaro sąlygas įvertinti besimokančiųjų nuotolinių studijų kokybę. / The main purpose of master work is to create the tool for quality evaluation in distance education systems. The Statistics module is described, created and realized in Moodle distance education system, because Moodle is open source software and is free to making it versatile for growing users’ needs. Statistics module helps to relate student‘s mark and his/her number of visits in course material. In this module was fitted method of correlation coefficient calculation. Such module allows evaluating the study quality of students’ in distance education.

Ekonomiką kartais ištinka įvairios krizės, pasitaiko stichinių nelaimių ar kitokių reiškinių, kurie iš esmės paveikia ekonomikos elgesį. Šis poveikis labai gerai atsispindi ekonominių rodiklių laiko eilutėse, kurių elgesys po tam tikros krizės ar stichinės nelaimės gali pakisti kardinaliai. Toks pasikeitimas paprastai vadinamas struktūriniu pasikeitimu. Tačiau dažnai pasitaiko atvejų, kai plika akimi sunku įžiūrėti esamus struktūrinius pasikeitimus, todėl šią problemą būtų galima išspręsti taikant specialius testus struktūriniams pasikeitimams aptikti. Šiame darbe nagrinėjami trys žinomi testai struktūriniams pasikeitimams nustatyti. Darbo tikslas palyginti šių testų galią ir pasiūlyti naują testą, kuris pasižymėtų patrauklesnėmis charakteristikomis. Nagrinėdami testus, skirtus struktūriniams pasikeitimams tikrinti, matėme, kad CUSUM testas nėra pritaikytas epideminio struktūrinio pasikeitimo atvejui, tuo tarpu kitų trijų testų, skirtų epideminiams struktūriniams pasikeitimams tikrinti, galia mažai skiriasi, tačiau naujai išvestas testas yra pranašesnis prieš kitus tuo, kad duomenyse esančių išskirčių netraktuoja kaip galimo struktūrinio pasikeitimo. / Sometimes there happen different crisis in economics, sometimes occur natural disasters or other phenomenons which substantially affect the behaviour of the economy. This impact reflects in a time series of economic indicators whose behaviour may go into the melting-pot after some crisis or natural disaster. Usually such a change is called a structural change. Very often structural change is hardly visible then this problem can be solved by applying special tests for detecting potential structural change. In this paper three known tests for identification of structural change are examined. The aim of this work is to compare the power of these tests and propose the new one which will have more desirable features. During the investigation of the tests that are designed for detecting structural changes it emerged that CUSUM test is not fitted for the case of epidemic structural change. Whereas the power of other tree tests that are designed for detecting epidemic structural changes differ narrowly, however the new test has the advantage against the other tests – it does not treat an outlier as a possible structural change.

The thesis deals with the evaluation of the natural recreational potential of a selected area. The evaluation is based on three different methods with different approaches. Selected methods are TERPLAN, Inverse Distance Weighting IDW and Focal statistics. The evaluation was situated in the Central Bohemian Region in the territory of Smecno, Ledce and Prelic. Input data for TERPLAN were created by vectorization of base maps. The TEPRLAN method needed to be edited for needs of selected area, because the original form of the TERPLAN is strictly focused on several landscape features. Input data for the other two methods comes from questionnaires. Landscape features were divided into five groups which each of them represent a specific sort of a recreation. These groups were rated according to the results of questionnaires. The IDW method evaluated the recreational potential on basis of distances between the centers of towns and landscape features. The result of this method is an interpolated value of recreational potential for its center. The recreational potential was counted for every town center and their merger gives a final raster layer as a result of recreational potential of whole area. The method of focal statistics was counted for mean and sum of input values. The raster layer of mean focal statistics represent a distribution of important landscape features in area. Second method of focal statistics with sum leads to the results that summarize recreational potential of each segment in area. Results of these three methods were supplemented with field research. According to the results of all methods was selected part of area with greatest recreation potential where was situated plans to boost actual potential. These plans should bring recreation opportunities closer to the public. Outcomes of this thesis can be used as input for next strategic planning development of this area.

Main goal of the diploma thesis is to describe household consumption and its survey in the Czech Republic not only from the macroeconomic but mainly from the microeconomic standpoint. Consumption expenditures are the main subject of many long-term analysis and forecasts which help by implementation of economic and politcal precautions. In connection with the historical development of statistic as a scientific disciplin there is also a significant stress on a methodical development of household budget surveys which examine consumption expenditures of different social groups and household types. After the analysis of development and structure of household consumption surveyed by National Accounts and Household Budget Surveys the attention is given also to household consumption in member states of the European Union among which is also the Czech Republic.

The drug use is a big problem of today world. The impact of drug use affects all members of human society -- individuals, families, communities and even whole states. We can describe the situation of drug use by means of analysis of drug use in the particular districts of the Czech Republic. This diploma thesis focuses on the identification of the social, economic and demographic factors that contribute to the appearance of socially pathologic environment of drug use. The results of this thesis can be used for an identification of regions in jeopardy of drug use and for the reduction of influence of particular factors.

Currently, there is an urgent need to conduct analysis of teaching statistical courses at the Faculty of Management University of Economics in Prague in order to analyze the current teaching methods, which are at the time of this thesis in the current academic year 2009-2010. Another aim is to propose a new method of teaching that reflect emerging trends in education, which would help students to understand and absorb the learning.

This diploma thesis deals with statistical monitoring of strength properties of aluminium. The theoretical part is focused on the description of mechanical properties of aluminium, the influence of corrosion on aluminium and its alloys, the use of aluminium in various industries. Furthermore, the theoretical part presents statistical monitoring with a focus on the Minitab program. In the practical part there is experimental measurment which includes the comparison of results, in which the tensile properties of aluminium not influenced by corrosion are compared with effects of the corrosion bath,with impacted samples that were in the corrosion chamber for 300, 500 and 700 hours. Furthermore, there are presented various statistical methods for evaluation of tensile test results.
