Nowadays, Google estimates that more than 1000 billion the number of images on the internet where the classification of this type of data represents a big problem in the scientific community. Several techniques have been proposed belonging to the world of image-mining. The substance of our work is the application of swarm intelligence methods for the unsupervised image classification (UIC) problem following four steps: image digitalization by developing a new representation approach in order to transform each image into a set of term (set of pixels); image clustering using three methods: firstly a distances combination by social worker bees (DC-SWBs) based on the principle of filtering where each image must successfully pass three filters, secondly Artificial social spiders (ASS) method based on the silky structure and the principle of weaving and the third method called artificial immune system (AIS); For the authors' experiment they use the benchmark MuHavi with changing for each test the configuration (image representation, distance measures and threshold).

The accumulation of secretions in the airways of ventilator-dependent patients is a common problem, and if not detected and treated in due time, it greatly increases the risk of infections and asynchrony. Unfortunately, cardiogenic oscillation modifies the flow signal shape that can confuse clinical staff and modern lung ventilators. In this article, the authors use an artificial immune system algorithm in a pre-processed flow signal. The authors' approach was able to automatically detect the presence or absence of airway secretions, even if the sample contains the influence of cardiogenic oscillation. The training and validation of the algorithm was carried out using a database containing flow signals of 457 respiratory cycles, obtained from three patients in different ventilation modes. The algorithm trained with 60% of the base cycles, was able to achieve specificity and sensitivity above 0.96 in the classification of the remaining cycles of the base.

In the article the practical aspect of application of principles of biological immune system for solving the problem of analysis and classification of email is viewed. In the capacity of analyzed emails ordinary emails (electronic mail) and mails from closed systems (electronic document flow or business management systems) were taken. In the article two-classification artificial immune system was developed with further comparison of effectiveness of their usage with naive Bayesian classification algorithm. Practical realization of the developed system with the application in the system of analysis of emails of the commercial structure is carried out.

Given the diversity of anatomical and functional manifestations of congenital anorectal malformations, the most relevant remains development of classification of this pathology, for the same understanding by doctors of the manifestations of this defect and developing optimal common criteria for treatment tactics and strategies. The paper presents historical and current information on the classification of anorectal malformations in children. The main contradictory issues of the existing classifications are identified. The relevance of the use of Krickenbeck classification in the treatment of these defects is highlighted. Under the influence of different colorectal schools, historically, different educational and methodological approaches to the treatment of anorectal malformations. The first International Congress of Pediatric Surgeons was held in Melbourne, Australia, in 1970. The Melbourne meeting established an international classification of anorectal malformations. It was based on the development of defects at the stages of embryogenesis and their division by sex. Also, they are divided into: low, intermediate and high anorectal malformations. The second World Meeting of Pediatric Surgeons was held in Wingspread, Wisconsin, USA, in 1984, when F. D. Stephens and E. Smith, with a group of experts from around the world, proposed a detailed PAHR classification. The advantage of the Wingspread classification was that it could be used to predict the most optimal surgical treatment for various variants of anorectal defects. The third international conference on the development of standards for the treatment of congenital anorectal malformations took place in Krickenbeck, Germany, in 2005. This conference radically changed the latter classification, removing the terms «low», «intermediate» and «high» and the differences between female and male anomalies. The assessment depended on the presence and type of fistula. The reason for adopting such a classification was the great difficulty in comparing the results of different operations according to the old Wingspread classification. The peculiarity of this classification is the great contribution of colleagues from the Indian and Asian subcontinents to the surgical treatment of several anomalies, in particular: Pouch colon, which are rare in other countries. Today, pediatric surgeons in Ukraine generally do not use the Krickenbeck classification, despite the fact that it is generally accepted in most countries. This leads to the application of different approaches to the surgical treatment of congenital anorectal malformations, which emphasizes the relevance of further study of this issue. The informed consent of the patient was obtained for conducting the studies. Key words: congenital anorectal malformation, classification, children.

AbstractDespite of the political instability in South Korea, there are strong and solid relations between universities and industry. These relations continue to lead economic growth and technical innovation in this country. This is the conclusion reached by Reuters in the third annual classification of Asian and Pacific universities, working on achieving progress in sciences and creating new technologies [29]. Korea Advanced Institute of Science and Technology, currently known as KAIST, is ranked the first for the third year in a row. Historically speaking, KAIST is the oldest Korean university dedicated for research, sciences, and engineering. It has three branch campuses in the following cities: Daejeon, Seoul, and Busan. The university produces a large number of innovations and applies for more patents than the other 75 universities on the list. In addition, researchers all over the world cite highly the research and patents of this university.

The article tells about the life and professional activities of the famous Slavist A.D. Dulichenko. Focusing on his interest in the study of micro-languages, the author emphasizes the influence of the national tradition on the formation of an approach to the study of linguistic rarities. In the overview of Professor Dulichenko’s main achievements in Russian studies, the author emphasizes his contribution to the world Slavic studies and the study of the languages of Slavia in the cultural space of traditions and times. Evaluating Dulichenko’s research in terms of the Humanities in the 21st century, the author draws attention to the multidimensional nature of his research method as well as polyglotticism, and deep knowledge of regional characteristics of microlanguages. Drawing on numerous books by Dulichenko, namely Introduction to Slavic Philology, which was the first to include detailed information about the Rusin and other minor languages and make it part of the syllabus for Philology in Russia, the author concludes that it is necessary to revise the traditional understanding of this discipline in higher education. The author pays special attention to the Compendium- Reader on Slavic Microlanguages – documentary evidence of the diversity of Slavia in its written traditions and oral forms of expression. Analyzing the structure of the book and highlighting its conceptual provisions, the author actualizes Dulichenko’s ideas about the status of literary microlanguages and their place in the classification of Slavic languages.
