В работе рассматривается задача исследования зависимости между двумя множествами номинальных признаков. Производится поиск связей между множествами, где в качестве меры зависимости рассматривается коэффициент неопределенности. Для расширения исходных множеств используются алгебраические методы: алгоритм быстрого перечисления точек грассманиана.
Отличие работы от других: поиск не только наибольших связей между множествами, но и самых устойчивых симптомов, в смысле уменьшения количества значимых связей и снижения уровней зависимости при их исключении из совокупностей , названных номинативными представителями.
Были получены следующие результаты: Получены искомые подмножества признаков по алгоритму быстрого перечисления точек грассманиана и наилучшие связи между получившимися подмножествами. Реализованы два метода поиска номинативного представителя: частотный способ и метод, основанный на удалении признаков. Получены номинативные представители обоих множеств при помощи методов многомерной статистики.

Canonical analysis of categorical data with application in marketing. Scientific Supervisor: Alekseeva Nina Petrovna. Field of study: Applied Mathematics and Computer Science. Profile: Computational Stochastics and Statistical Models.
In work the dependence research problem between two sets of nominal attributes. Search of communications between sets where as a metrics used uncertainty coefficient. For expansion of initial sets used algebraic methods: algorithm of fast enumeration grassmanian points.
Unlike other works: search not only the greatest communications between sets, but also the steadiest symptoms.
Results: Received the desired subset by algorithm of fast enumeration grassmanian points and the best connections between subsets. Implemented two methods of search nominative representative: the frequency method and a method based on removing the attributes. Obtained nominative representatives of both sets using multivariate statistical methods.

To the 100th anniversary of Irina Antonova
No full textThis article is dedicated to the legendary Russian museum figure Irina Antonova (20.03.1922 —
30.11.2020), who worked at the Pushkin State Museum of Fine Arts for 75 years, 52 years of
which as its director. The development of the Pushkin State Museum of Fine Arts under the
leadership of Irina Antonova is seen by the author of this article as part of the evolution of
museum work in the Soviet Union and the Russian Federation. The article emphasizes that the Pushkin Museum was often ahead of its time, laying the groundwork for major changes. For
example, with the opening of the Museum of Private Collections as part of the State Museum
of Fine Arts, the rehabilitation of private collecting in the country took place. The December
Nights festival created by Irina Antonova in collaboration with the brilliant pianist Svyatoslav
Richter in 1981 became a matrix of art festivals that took place in various museums of the
country during the following decades. The Pushkin State Museum of Fine Arts was charged
with promoting Western art in the USSR, of which it brilliantly took the advantage when
started displaying works by Picasso, Matisse, Leonardo da Vinci’s Mona Lisa, masterpieces
of drawing from the Albertina Museum in Vienna, Western European and American paintings
from American museums and others famous exhibitions. This is the visible part of Irina
Antonova’s dynamic activity. She approached academic work no less thoroughly, as well as the
organization of study and cataloguing of the collection of the State Museum of Fine Arts. And,
of course, much credit must go to Irina Antonova for preparing the program for the development
and reconstruction of the Pushkin Museum, which has been repeatedly revised and is
being finalized before our very eyes under the direction of Marina Loshak

<p><strong>Background</strong><br />
The aim of research is retrospective studying of the frequency and structure of affect by malignant neoplasms of the maxillofacial area in one of the industrial district of Kharkov.<br />
<strong>Methods</strong><br />
The results of retrospective studying of the frequency and structure of affect by<br />
malignant neoplasms in the maxillofacial area in one of the industrial districts of<br />
Kharkiv are described in the article. The retrospective analysis was carried out taking into account the age, sex, localization and disease stages.<br />
<strong>Results</strong><br />
According to the results of the performed research it was established that the incidence during 10 years tended to growth, predominantly with the aged and senile people. The high percentage of the initially revealed patients with the advanced stages of disease was defined.<br />
<strong>Conclusions</strong><br />
Performing the retrospective analysis of the frequency and structure of malignant<br />
neoplasms of the maxillofacial area among the population of the industrial district of Kharkov, it should be stated that over the last decade the incidence trended upwards.<br />
Analysis of the frequency of detection of certain stages of the disease indicated that primary revealed advanced forms of cancer patients.<br />
The obtained data can be evaluated as the consequence of insufficient efficiency of preventive examinations and late address of patients.</p>oral cance
