To the improving of high-tech medical care access for the patients with severe dermatoses

Authors analyzed the normative legal documents that at different stages determined the general procedure for organizing the provision of high-tech medical care and the sources of its financing. Statistical data on the provision of hightech medical care for the population of the Russian Federation on the profile of "dermatovenerology" are presented. The authors have shown in dynamics that since the release of high-tech medical care as a separate type of medical care (1992), there is the change in the number of medical organizations that provide this type of medical care in the Russian Federation. The authors outlined the main problems of low accessibility and provision of the population of certain subjects of the Russian Federation with this type of medical assistance. The list of nosological forms on the profile of "dermatovenerology" remains extremely insufficient for today, the severity of the course and approaches to treatment of which can be attributed to the number of high-tech medical care. The experience of the work of the federal medical organization in the provision of high-tech medical assistance on the profile of "dermatovenerology" is presented. Proposals have been formulated to improve the quality, availability and improvement of the model for providing high-tech medical care to patients with the most severe dermatoses. The analysis of the literature data, normative legal documents and the experience of the medical organization of federal subordination is presented. The review of step-by-step development and increase of accessibility of high-tech medical aid on the profile of "dermatovenerology" was conducted

Exclusive pp→nnπ+π+pp \to nn \pi^{+}\pi^{+} reaction at LHC and RHIC

We evaluate differential distributions for the four-body $p p \to n n \pi^+ \pi^+$ reaction. The amplitude for the process is calculated in the Regge approach including many diagrams. We make predictions for possible future experiments at RHIC and LHC energies. Very large cross sections are found which is partially due to interference of a few mechanisms. Presence of several interfering mechanisms precludes extraction of the elastic $\pi^+ \pi^+$ scattering cross section. Absorption effects are estimated. Differential distributions in pseudorapidity, rapidity, invariant two-pion mass, transverse-momentum and energy distributions of neutrons are presented for proton-proton collisions at $\sqrt{s}$ = 500 GeV (RHIC) and $\sqrt{s}$ = 0.9, 2.36 and 7 TeV (LHC). Cross sections with experimental cuts are presented.Comment: 22 pages, 18 figures, calculations have been corrected, new processes added, discussion expanded in print in Phys. Rev.

SEM and AFM studies of two-phase magnetic alkali borosilicate glasses

The morphology and composition of four types of two-phase alkali borosilicate glasses with magnetic atoms prepared by inductive melting have been studied. The results of scanning electron microscopy point to uniform distribution of Na, Si, and O atoms in these samples whilemagnetic iron atoms formball-shaped agglomerates. The magnetic properties of these agglomerates have been confirmed by magnetic force microscopy. Atomic force microscopy had shown that in these samples two different morphological structures, drop-like and dendrite net, are formed. The formation of dendrite-like structure is a necessary condition for production of porous magnetic glasses. The obtained results allowus to optimize the melting and heat treatment processes leading to production of porous alkali borosilicate glasses withmagnetic properties. The first results for nanocompositematerials on the basis ofmagnetic glasses containing the embedded ferroelectrics KH2PO4 demonstrate the effect of applied magnetic field on the ferroelectric phase transition.

Organization of internal control of quality of medical care (Faculty Clinics of Irkutsk State Medical University)

Currently, there is no normative document at the federal level that determines the format of the organization of internal control of medical care quality in a medical organization. The system of standardization in the sphere of public health of the Russian Federation remains incomplete. In this regard, in the multidisciplinary medical organization, innovative approaches have been developed and implemented in the management of the medical care quality and ensuring the safety of medical activities: the development of a number of local regulatory documents; strengthening the expert institute (setting up a department for quality control and safety of medical activities); increasing the role of the internal expertise of the quality of medical care; standardization of medical care; improving the organization of work of middle and junior medical links; strict adherence to the three-stage internal quality control with the obligatory presence of self-control when monitoring the quality of work of medical, middle and junior medical personnel. The authors show the dynamics of the main indicators of the quality of care at the stages before and after the introduction of new approaches to improve the internal quality control of medical care. The presented data testify to the effectiveness and expediency of the proposed measures

The+basic+algorithm+for+the+design+and+construction+of+a+monocultural+innovation+organization

Algorithmization of management activities in the transition to the digital economy is one of the most important tasks of modern management science. Sketch design is defined by the algorithm creation tool. This algorithmization method is applied to the processes of choosing the type of a homogeneous product, its quality and other consumer properties, utility for the consumer and manufacturer. Products are classified according to their purpose and the resources for their production. The quality of the product is defined as the ratio of the actual properties of the product to the normative ones, while it is necessary to take into account the influence of manufacturing defects, which entails a transition from linear to non-linear quality functions. The cumulative assessment of the product for the consumer is determined taking into account his subjective assessment of the properties of the product, expressed in the weight of the quality of individual utilities. For a manufacturer, the aggregate assessment of product quality directly depends on the main properties of the product, taking into account its other properties, and inversely depends on the cost of purchasing it, taking into account their functional elasticity. The algorithm is recommended for use by specialists dealing with algorithmic management activities

The article discussesthe current problem of food quality control, the content ofstrontium-90 and cesium - 137 in the body of wild game birds-wild game inhabiting the territory of the Republic of Sakha (Yakutia). The object for research were carcasses of wild game 3 species: black grouse; partridge; grouse. Radiation safety of wild game as a food product was determined by its compliance with permissible levels of specific activity of radionuclides, in particular 137Cs and 90Sr. These indicators are regulated by TR CU 021/2011 “on food safety”. According to the long-term (2013-2017) results of our studies 137Cs and 90Sr in carcasses of wild game, Northern, Central, Vilyuisk and southern ecological zones of the Republic of Sakha (Yakutia) was not found to exceed the permissible concentration. As a result of our research, the following results were obtained: the content of 137Cs and 90Sr in grouse carcasses: southern - 70.54±0.71 and 26.43±2.54; Central-64.81±0.18 and 20.89±1.95; Vilyuiskaya - 73.12±0.01 and 28.48±1.18. Black grouse does not live in the Northern ecological zone. The results of the study of partridges are as follows: South-69.04±2.95 and 28.17±0.05; Central - 58,69±2,18 19,87 and±0,39; Vilyui - 70,84±1.55 and 27,87±0,04; North - 28,17±0.05 and of 10.83±0,50. In the study of grouse is established: the content of radionuclides in the southern zone - 71,24±1,95; Central was 60.05±0.01 and of 21.11±1,95; Vilyui - 71,11±0.55 and of 11.47±0,32. According to the results of our studies, the data of exceeding the maximum concentration of 137Cs and 90Sr in the carcasses of wild game in all ecological zones of Yakutia were not established.Обсуждается актуальная в наше время проблема – контроль качества продуктов питания, в частности, содержания цезия-137 (137Cs) и стронция-90 (90Sr) в организме диких промысловых птиц – боровой дичи, обитающей на территории Республики Саха (Якутия). В регионе представители тетеревиных птиц (тетерев, куропатка, рябчик) являются объектом традиционного промысла местного населения и пользуются повышенным спросом на внутреннем рынке, поэтому данная тема является весьма актуальной. Объектом для исследований были тушки боровой дичи трех видов: тетерев, куропатка, рябчик. Радиационную безопасность мяса дикой промысловой птицы как пищевой продукции определяли ее соответствием допустимым уровням удельной активности радионуклидов: 137Cs и 90Sr. Нормативы элементов описаны ТР ТС 021/2011 «О безопасности пищевой продукции». В результате наших исследований получены следующие результаты: содержание 137Cs и 90Sr в тушках тетерева в Южной зоне – 70,54±0,71 и 26,43±2,54, Центральной – 64,81±0,18 и 20,89±1,95, Вилюйской – 73,12±0,01 и 28,48±1,18 Бк/кг. В Северной экологической зоне тетерев не обитает. Результаты исследования куропаток на содержание 137Cs и 90Sr следующие: Южная зона – 69,04±2,95 и 28,17±0,05, Центральная – 58,69±2,18 и 19,87±0,39, Вилюйская – 70,84±1,55 и 27,87±0,04, Северная – 28,17±0,05 и 10,83±0,50 Бк/кг.
