Bonitní a bankrotní modely / Financial health models and bankruptcy prediction modelsONDOKOVÁ, Lucie January 2016 (has links)
The main aim of the master thesis is to compare of different methodologies of financial health models and bankruptcy prediction models and their cause to company classification. The work deals with the applicability of models on the sample of 45 prosperous companies and 45 companies that were initiating in insolvency process. Sample contain about 33 % companies from building industry, 33 % retail, 16,7 % manufacturing industry and 16,7 % of the other industries mainly services. The special kind of contingency table - the confusion matrix - is used in the methodology to calculate sensitivity, specificity, negative predictive, false positive rate, accuracy, error and other classification statistics. Overall model accuracy is obtained as a difference between accuracy and error. Dependencies of models are acquired based on Pearson´s correlation coefficient. The changes (removing of grey zone and testing new cut-off points) in models are tested in the sensitivity analysis. In practise part there are about 12 financial models calculated (Altman Z´, Altman Z´´, Index IN99, IN01 and IN05, Kralicek Quicktest, Zmijewski model, Taffler model and its modification, Index Creditworthiness, Grunwald Site Index, Doucha´s Analysis). Only two financial indicators (ROA and Sales / Assets) in results were important as crucial part for more than one model. Then are classifications of companies in models determined. It shows that the best models according to overall accuracy are Zmijewski and Altman´s Z´´. On the other hand the worst models are index IN99 and both versions of Taffler´s model. The classification is not caused excessively by extreme values, year of the model creation or country of the origin (hypothesis 1). Based on results it is suggested that the bankruptcy prediction is an accurate forecaster of failure up to three years prior to bankruptcy in most examined models (hypothesis 2). It is observed that the type of model and industry influence the classification of models. In the end, the changes based on sensitivity analysis in the worst companies are made. All of three changes have increased overall classification accuracy of models.

Klasifikace žánrů pomocí strojového učení / Genres classification by means of machine learningBílek, Jan January 2018 (has links)
In this thesis, we compare the bag of words approach with doc2vec doc- ument embeddings on the task of classification of book genres. We cre- ate 3 datasets with different text lengths by extracting short snippets from books in Project Gutenberg repository. Each dataset comprises of more than 200000 documents and 14 different genres. For 3200-character documents, we achieve F1-score of 0.862 when stacking models trained on both bag of words and doc2vec representations. We also explore the relationships be- tween documents, genres and words using similarity metrics on their vector representations and report typical words for each genre. As part of the thesis, we also present an online webapp for book genre classification. 1

Ošetřovatelské klasifikační systémy NANDA International, NIC, NOC a jejich využití při hodnocení bolesti u dětí po ortopedických operacích / Nursing classification systems NANDA International, NIC, NOC and their use in pain management in children after orthopedic surgeryDYMÁKOVÁ, Kateřina January 2013 (has links)
The aim of Graduation thesis is utilisation of classifying systems NANDA International, NIC and NOC by solving of nursing issue Acute pain at children after orthopaedical major surgeries. Part of successful and well adjusted treating of pain is its careful recording into medical documentation. For the goal of creating of the documentation there could be used international classification systems NANDA Intermational, NIC and NOC, with their aid it is possible to complete comprehensive aid, which describes each step of the treatment praxis. The first goal of the thesis was to map awareness of the nursing staff of systems mentioned. The second goal was creating of an aid using separate parts of system NANDA International, NIC and NOC aimed to diagnostics, solving and evaluation of the Problem of Acute pain at children after major surgeries. The last goal was verifying of beneficial effect of the new created documentation in praxis. The first research specimen was build by 58 nurses from four hospitals in Czech Republic working in children's departments. It was approached 8 hospitals altogether, nursing staff of four of them participated in the survey. The second research specimen was build by nurses from Children department in Hospital Pribram. The third part of research was built by 5 children admitted to hospital. The criterion for their attendance was their major surgery operation and their diagnosis Acute Pain. We used the half structured questionnaire for collecting of figures, models method and ideas of content analysis of documents and quasi experiment. Particular steps of research were realised as following: In the period of time February 2013 till March 2013, 60 questionnaires were distributed. Return was 100%. Cooperation with nurses from hospital Pribram lasted from 1. 3. 2013 until 29. 3. 2013. The medical documentation was created during this period of time, the method was tested and evaluated from nurses point of view. We found out, the nurses are familiar with system NANDA International but not aware of other two systems mentioned above. It was researched on statistical basis dependency between awareness of the specific classifications and the highest education grade and age of the nurses was considered, as well. During our stay in Hospital in Pribram, the practical aid was created aimed to evaluation and solving of the issue Acute Pain after orthopedical surgeries. This aid was tested in the same department then. A record was taken into amended forms by children after major surgeries. Concerning forms aimed for nursing praxis there were recorded not only intensity, characters and localisation of the pain, there were recorded which significant marks and connected factors from NANDA International Taxonomie II were possible to observe by particular children. There were recorder information which activities were used for children into forms containing interventions and activities drawn from from classification NIC. Last but not least, the pain was considered on the daily basis using classification NOC. As we found out from discussions with nurses cooperating during the research, more than a half of them perceive the use of the above mentioned aid very contributive. One idea appeared, the aid is needed in the Czech nursing practice. From this point of view, it would be beneficial to pay attention to this issue in the future.

Monozoické tasemnice rodu \kur{Monobothrium} (Cestoda: Caryophyllidea) z Palearktické a Nearktické zoogeografické oblasti / Monozoic tapeworms of the genus \kur{Monobothrium} (Cestoda: Caryophyllidea) from the Palaearctic and Nearctic zoogeographical regionsČAPKOVÁ, Lenka January 2014 (has links)
The genus Monobothrium Diesing, 1863 includes two Palaearctic species (parasitizing cyprinids, possessing postovarian vitelline follicles, lacking an external seminal vesicle and having digitiform or cuneicrispitate scolex) and five Nearctic species (parasitizing catostomid fish, lacking postovarian vitelline follicles, possessing an external seminal vesicle and having loculomonobothriate, monobothriate or loculotruncate scolex). Based on these morphological differences, supported by preliminary molecular data, five North American species (originally placed in Monobothrium) are proposed to be transferred to Promonobothrium Mackiewicz, 1968 as new combinations. European species Monobothrium auriculatum Kulakovskaya, 1961 should be transferred to Caryophyllaeus Gmelin, 1790 as C. auriculatus n. comb. As a result of this transfer, Monobothrium becomes monotypic, with M. wageneri Nybelin, 1922 representing its only species.

Klasifikace ubytovacích zařízení v České republice a v zahraničí / The classification of accommodation facilities in the Czech Republic and foreign countriesKOHOUTOVÁ, Klára January 2010 (has links)
The aim of my thesis is to aprise the reader with the meaning and purpose of classification of accommodation in the Czech Republic. I am trying to compare the classification of 2009 with the present classification valid since 2010 till 2012 but also with classifications of other countries. For this comparison I chose the classification of the accommodation in Great Britain which is according my opinion very detailed but also with the classification of other, mainly European countries (with the American classification I compare the classification only in general terms).
