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:: Dispute and controversy are parts of our culture and cannot be omitted on the Internet (where it becomes more anonymous). There have been many studies on controversy, especially on social networks such as Wikipedia. This free on-line encyclopedia has become a very popular data source among many researchers studying behavior or natural language processing. This paper presents using the category structure of Wikipedia to determine the controversy of a single article. This is the first part of the proposed system for classification of topic controversy score for any given text.

Opis:: Airborne laser scanning (ALS) is one of the LIDAR technologies (Light Detection and Ranging). It provides information about the terrain in form of a point cloud. During measurement is acquired: spatial data (object’s coordinates X, Y, Z) and collateral data such as intensity of reflected signal. The obtained point cloud is typically applied for generating a digital terrain model (DTM) and a digital surface model (DSM). For DTM and DSM generation it is necessary to apply filtration or classification algorithms. They allow to divide a point cloud into object groups (e.g.: terrain points, vegetation, etc.). In this study classification is conducted with one extra parameter–intensity. The obtained point groups were used for digital spatial model generation. Classification is a time and work consuming process, therefore there is a need to reduce the time of ALS point cloud processing. Optimization algorithm enables to decrease the number of points in a dataset. In this study the main goal was to test the impact of optimization on the results of a classification. Studies were conducted in two variants. Variant 1 includes classification of the original point cloud where points are divided in the groups: roofs, asphalt road, tree/bushes, grass. On variant 2 before classification, an optimization algorithm was performed in the original point cloud. Obtained from these two variants object groups were used to generate a spatial model, which was then statistically analyzed.

Opis:: Background: Orofacial clefts are the most common congenital anomalies of the head and neck. Aim: The aim of this paper is to present own group of patients with different types of isolated orofacial clefts. Material and method: A retrospective study presenting patients with different facial clefts was carried out in the group of 473 patients born in the city of Lodz. Results: In the whole group there were: 434 patients with cleft lip and/or palate, 28 with nose clefts and 11 with rare facial clefts classified according to Tessier categorization. Conclusion: In our group, the majority of cases comprised of typical cleft lip and/or palate. Nose clefts are not always a part of craniofacial clefts, but isolated nose clefts can occur and can be observed as midline defects or ala nasi anomaly. A simple system may be adequate for surgical repair, with the more detailed classification schemes important for further understanding of the disease.

Opis:: Efforts of the scientific community led to the development of multiple screening approaches for COVID-19 that rely on machine learning methods. However, there is a lack of works showing how to tune the classification models used for such a task and what the tuning effect is in terms of various classification quality measures. Understanding the impact of classifier tuning on the results obtained will allow the users to apply the provided tools consciously. Therefore, using a given screening test they will be able to choose the threshold value characterising the classifier that gives, for example, an acceptable balance between sensitivity and specificity. The presented work introduces the optimisation approach and the resulting classifiers obtained for various quality threshold assumptions. As a result of the research, an online service was created that makes the obtained models available and enables the verification of various solutions for different threshold values on new data.

Opis:: In the article a quantitative and valuable structure of transactions of land properties has been analyzed, especially taking into consideration lands intended for a dwelling-houses building, in Poland, in the years 2009-2011. Using one of the multivariate analysis methods the analysis and the evaluation of the spatial diversification of the voivodeships with regard to the analyzed properties turnover were done. Statistical data came from the Central Statistical Office publication titled ”Properties turnover”. After the reduction of the initial set of diagnostic features with parametric method, the final set, which was a basis for the voivodeships’ classification, was obtained. Finally five classes of voivodeships similar with respect to the turnover of lands intended for a dwelling-houses building were obtained.

Opis:: Suevite is the impact breccia rock with glass particles that attracts the attention of researches because of its broad variability. Many characteristics of the environment and impact process determine this attention, and, in consequence, various descriptions and names of the rock are presented in the literature. The Rochechouart impact structure is a good example of suevite or suevite-like rock diversity in its several localities (Rochechouart, Chassenon, LaValette, Montoume). The relationships between suevite components and target rocks can be exemplified by Kara and Popigai and other astroblemes. To simplify the classification of the rock, its main and more stable components (matrix, glass, clasts) should be considered. More detailed analysis of the suevite components can be used for sub-classifications, similarly as it is done for other Earth rocks. In addition, a short description of suevites from various astroblemes is presented. The possibility of the monomict suevite breccia creation is discussed.

Opis:: Objective: To assess taekwondo sparring performance variables, such as joint ranges of motion, reaction times, and kicking foot speeds, to serve as a framework for developing sport-specific classification in Para-taekwondo competition. Methods: After a standard taekwondo warm up, athletes executed five popular scoring techniques, back kick, cut kick, fast kick, turning kick, and tornado kick five times each (25 total). Kinematic and kinetic variables were recorded by a motion capture system of seven infrared cameras and two force plates. Maximum joint range of motion, foot velocities, and reaction time were calculated. Results: Collapsed over kick, maximum hip abduction motion, maximum hip flexion, maximum knee flexion, peak foot velocity, reaction time for male athletes were 47.8 ±10.4°, 46.3 ±7.6°, 105.3 ±14.0°, 11.5 ±2.4 m/s, and 0.46 ±0.06 s respectively. maximum hip abduction motion, maximum hip flexion, maximum knee flexion, peak foot velocity, reaction time for female athletes were 49.1 ±6.8°, 43.9 ±11.0°, 94.2 ±13.7°, 10.9 ±2.2 m/s, and 0.48 ±0.11 s respectively. Conclusions: The results of this study provide a foundational framework for future studies designed to compare and assess Para-taekwondo athletes with various physical and neurological impairments. From this, future studies may move towards developing practical on-site sport specific testing methods which may ultimately assist in making taekwondo-specific classification for Para-taekwondo competitions.
