[The medical support of large-scale international events].

The medical support is one of the most important components of effectiveness of international sports events. The purpose of the study is to analyze results of implementation of organizational approaches to medical support of international sports competitions at the World Skills Championship 2019 in Kazan, previously developed and successfully approved on the model of the 2013 World's Students Games (Kazan). The medical support plan included preparation of regulatory base, resources of medical infrastructure at sports venues, including personnel training and measures to eliminate the medical and sanitary consequences of emergencies. At the objects of the Championship, 21 medical aid posts, 23 mobile medical teams functioned, and 22 ambulance teams were on duty. The estimated number of medical staff involved in work at the Championship venues was 120 people, or 8.9 people per 100 contestants. There were 1883 registered medical requests. The largest percentage of requests fell on staff (29.6%), volunteers (20.4%), contestants (18.1%) and visitors (10.7%). Among the accredited persons, the most requested medical assistance was for respiratory diseases (8.5 ‰), diseases of the nervous system (8.4 ‰) and injuries (7.2 ‰). The application of developed approaches to medical support of international sports competitions for the World Skills World Championship allowed to organize provision of medical care to client groups at high level.

[The organizational principles of medical support of ceremonies of opening and closing international sport competitions (as exemplified by the XXVII Summer World Student Games of 2013 in Kazan)].

The results of implementation of developed approaches to medical support of ceremonies of opening and closing international sport competitions are demonstrated by the example of the XXVII Summer World Student Games in Kazan in 2013. The ceremonies took place at the venue with capacity of 45,000 spectators. The number of requests for medical assistance during the opening and closing ceremonies was 5.1 and 2.5 per 1000 spectators and accredited participants, respectively. Six individuals were evacuated to hospitals (0.1 cases per 1000 spectators and accredited event participants). The experience of organization of medical support of opening and closing ceremonies of international sport competitions is of practical significance in the framework of preparation and holding of international events in Russia.

On the integrable elliptic cylindrical Kadomtsev-Petviashvili equation.

There exist two versions of the Kadomtsev-Petviashvili (KP) equation, related to the Cartesian and cylindrical geometries of the waves. In this paper, we derive and study a new version, related to the elliptic cylindrical geometry. The derivation is given in the context of surface waves, but the derived equation is a universal integrable model applicable to generic weakly nonlinear weakly dispersive waves. We also show that there exist nontrivial transformations between all three versions of the KP equation associated with the physical problem formulation, and use them to obtain new classes of approximate solutions for water waves.
