Opis:: Introduction: Third molars (TMs) are the most frequently impacted teeth due to the frequent lack of space in the dental arch resulting in their malposition or inability to erupt. Partially erupted TMs that cause recurrent inflammatory conditions must be removed. The aim of this study was to assess TM position on panoramic radiographs. Materials and methods: We evaluated 200 panoramic radiographs of patients 18-72 years of age. Teeth were assessed in terms of the presence of dental follicle, cervix/root ratio and root development stage. Maxillary TMs were assessed using the Archer and Pell and Gregory classifications, whereas the mandibular ones according to Pell and Gregory, Winter, IAN and Pederson classifications. Results: 622 TMs were assessed. In the maxilla, the most common type was A-positioned, vertically angulated TM with completely formed root/roots. In the mandible, the most common type was A1-positio- ned, mesioangular TM with completely formed root/roots and without enlarged follicle. According to Pederson’s index, 59.44% TMs were moderately difficult to extract. Most roots were in contact with inferior alveolar nerve. Conclusions: The use of the classifications mentioned above is helpful in assessment of the surgery difficulty level. In the long term this allows to increase the predictability of the procedure and minimize the intra- and post-operative complications.

Opis:: In the paper, the authors are presenting the outcome of web scraping software allowing for the automated classification of source code. The software system was prepared for a discussion forum for software developers to find fragments of source code that were published without marking them as code snippets. The analyzer software is using a Machine Learning binary classification model for differentiating between a programming language source code and highly technical text about software. The analyzer model was prepared using the AutoML subsystem without human intervention and fine-tuning and its accuracy in a described problem exceeds 95%. The analyzer based on the automatically generated model has been deployed and after the first year of continuous operation, its False Positive Rate is less than 3%. The similar process may be introduced in document management in software development process, where automatic tagging and search for code or pseudo-code may be useful for archiving purposes.

Opis:: Kin term patterns and language familieThe anthropologist G. P. Murdock has found a strong correlation between the kin term patterns (or feature-values) for the relative (feature) “sibling” and language families. This important finding for language classification, however, has not been pursued further. In particular, it has not yet been tested whether the kin term patterns domain as a whole, including the patterns for other features (“grandparents”, “uncles”, “aunts”, “nephews and nieces”, etc.), is sufficient to demarcate all language families from one another. This paper presents a large-scale computational profiling of all language families in terms of their kin term patterns. The most significant findings are: (i) that language families can be quite neatly differentiated on the basis of their kin term patterns, and therefore these patterns may be considered as strong indicators of genetic affiliation, and (ii) that the kin term patterns for the features “nephews and nieces (= siblings' children)”, “siblings”, and “siblings-in-law” - i.e. all features including the idea of siblings - are the best predictors of genetic affiliation, as they are significantly more frequently used in the profiles than any other feature. Modele terminologii powinowactwa i pokrewieństwa a rodzina językowaAntropolog G. P. Murdock odkrył silny związek między modelami powinowactwa i pokrewieństwa dla krewnych (rodzeństwa) a rodzinami językowymi. To ważne odkrycie w klasyfikacji języków nie było odpowiednio dalej wykorzystywane. W szczególności nie sprawdzono jeszcze, czy domena modeli powinowactwa i pokrewieństwa jako całości, w tym modele dla innych cech („dziadkowie”, „wujkowie”, „ciotki”, „siostrzeńcy i siostrzenice” itp.) są wystarczająco ukształtowane we wszystkich rodzinach językowych. W niniejszym artykule przedstawiono profilowanie komputerowe na dużą skalę wszystkich rodzin językowych pod kątem ich modeli powinowactwa i pokrewieństwa. Najważniejsze wnioski są następujące: (i) rodziny językowe mogą być zróżnicowane na podstawie modeli powinowactwa i pokrewieństwa, dlatego też te modele mogą być uważane za silne wskaźniki genetycznej przynależności, oraz (ii) modele dla cechy „siostrzeńcy i siostrzenice (= dzieci rodzeństwa)”, „rodzeństwo” i „rodzeństwo przyrodnie” - czyli wszystkie cechy, w tym rodzeństwa - są najlepszymi przesłankami genetycznej przynależności, ponieważ są znacznie częściej używane w profilach niż jakakolwiek inna funkcja.

Opis:: For the contemporary business, the crucial factor is making smart decisions on the basis of the knowledge hidden in stored data. Unfortunately,m traditional simple methods of data analysis are not sufficient for efficient management of modern enterprizes, because they are not appropriate for the huge and growing amount of the data stored by them. Additionally data usually comes continuously in the form of so-called data stream. The great disadvantage of traditional classification methods is that they assume that statistical properties of the discovered concept are being unchanged, while in real situation, we could observe so-called concept drift, which could be caused by changes in the probabilities of classes or/and conditional probability distributions of classes. The potential for considering new training data is an important feature of machine learning methods used in security applications (spam filtering or intrusion detection) or decision support systems for marketing departments, which need to follow the changing client behavior. Unfortunately, the occurrence of concept drift dramatically decreases classification accuracy. This work presents the comprehensive study on the ensemble classifier approach applied to the problem of drifted data streams. Especially it reports the research on modifications of previously developed Weighted Aging Classifier Ensemble (WAE) algorithm, which is able to construct a valuable classifier ensemble for classification of incremental drifted stream data. We generalize WAE method and propose the general framework for this approach. Such framework can prune an classifier ensemble before or after assigning weights to individual classifiers. Additionally, we propose new classifier pruning criteria, weight calculation methods, and aging operators. We also propose rejuvenating operator, which is able to soften the aging effect, which could be useful, especially in the case if quite ”old” classifiers are high quality models, i.e., their presence increases ensemble accuracy, what could be found, e.g., in the case of recurring concept drift. The chosen characteristics of the proposed frameworks were evaluated on the basis of the wide range of computer experiments carried out on the two benchmark data streams. Obtained results confirmed the usability of proposed method to the data stream classification with the presence of incremental concept drift.

Opis:: This chapter is focused on the application of association rules to classify medical data. There is no data mining technique that can produce consistent results for all types of medical data. The effectiveness of a data mining technique depends, among other things, on the type of data collected for study. The purpose of the following work is to see if combining two data mining methods will give better results than using them individually. For this purpose, data on breast cancer in women was used. The results showed that using a hybrid combination of association rules to produce a classifier can improve classification performance.

Opis:: This investigation intends to examine whether there is a correlation between the speed of execution of mathematical tasks successfully resolved and the execution speed of the physical motor control tasks. The specific objectives defined are: knowing if there is a correlation between the times obtained in the activity of Mathematics and times in the activity of Motor Expression; Verify if there is a correlation between the times obtained in the activity of Mathematics and times in the group activity; Verify if there is a correlation between the times obtained in Motor Expression activity and the times obtained in the group activity. The methodology adopted for the realization of this study falls mainly on a positive paradigm, assuming a correlational nature typology. The study was conducted with a group of 22 children. These children performed three timed activities, individually, one for each domain and for the group task. The data analysis was conducted using the statistical program SPSS (version 20). After analysis and processing of data we have obtained positive correlation for all tests, however with very different correlation coefficients. We had a correlation coefficient of r = 0.051 between the activity of Mathematics and the activity of Motor Expression, revealing a tiny positive correlation. The test between the activity of Mathematics and Group Activity originated the correlation index r = 0.749; revealing a moderate positive correlation. In the test between the activity of Motor Expression and Grupo Activity, we had a correlation coefficient r = 0.191, which indicates a weak positive correlation. It was still observable that these data change when we focus only on the results of children aged 5 years old. In the first a correlation index r =0.315 was obtained, changing from tiny to weak positive; the second got an index r = 0.843, changing from moderate to strong positive; the third got an index r = 0.678, and therefore the positive correlation moderate.

Opis:: This article focuses on the issue of drug nominations above the word level. It assumed that every jargon expression composed of two or more elements is a phraseologism. The analysis encompasses 274 phraseological expressions excerpted from the most recent lexicogra- phic sources. Among the analyzed drug nominations there were observed all kinds of expressions divided according to semantic as well as formal criteria. Moreover, phraseological phonetic, mor- phological-grammatical, word-formation and lexical variants were distinguished.
