Acute toxicity of chitosan samples was determined by the value of 50% lethal dose (LD50) in experiments on white nonlinear mice aged 2-2.5 months weighing 18-22 g, from which groups of 10 animals were formed. Chitosan preparations were administered once intraperitoneal in a volume of 0.5 cm3 (solution in acetic acid). For control animals, an aqueous solution of acetic acid with a pH of 5.8 was used. The animals were observed after injections of the tested drugs for two weeks.  We took into account the appearance and behavior, the state of the coat and visible mucous membranes, the attitude to feed, mobility, volume and frequency of breathing, the timing of the death of animals or their recovery. The radioprotective properties of chitosan against ionizing radiation were investigated. The preventive and therapeutic effect of low-molecular chitosan in intraperitoneal administration at doses of 200 mg / kg live weight in experiments on male mice weighing 20-25 g, subjected to gamma irradiation at doses up to 800 BER (BER - man roentgen equivalent) on the installation "Gamma-panorama" (radiation source Cs137, duration 58.5 min.). It was shown that mice of the experimental group I, which were administered chitosan three days before irradiation, remained alive during the entire observation period (30 days.). Animals II, III and IV of the experimental group was injected with 3, 9 and 22 days after irradiation, the survival rate to the end of the experiment they accounted for 86, 43 and 29%, respectively, with 100% mortality in the control (irradiated animals without the use of chitosan) and intact animals in the control II (non-irradiated animals).

A Structural Approach to the Classification of the Letters in the Images
Authors: Липкина Анна , Lipkina Anna , Местецкий Леонид , Mesteckiy Leonid
Published: November 2019

The paper proposes a mathematical model of the concept of grapheme, the main purposes of which are to formulate a strict definition of the concept of «grapheme» and to highlight the overall structure of images of the same characters. The construction of the grapheme is based on a continuous skeletal approach, which involves the construction of the skeleton of a binary image of the symbol with its subsequent regularization. We also use the constructed model for the problem of text recognition on a digital image. For this purpose, features based on vertex positions in the grapheme model are extracted from the model, and the classifier is trained on these features. It determines which class the grapheme selected from the binary image of one symbol belongs to. We also consider the method of processing the input image with text for better selection of characters, lines and words. The experiments show the performance of the proposed grapheme model. The classification algorithm shows results comparable with modern methods of text recognition.

Published: November 2019

This article shows the possibility of combining modern software development technologies. SCADA systems usually do not use the full power of modern visualization technologies (rendering of three-dimensional objects, spatial transformation, etc.). In addition to graphics, users of these systems have a question about the possibility of using GIS systems to facilitate the determination of the location of objects (on global, local, and other maps). Using all the technologies described in this article, a system was developed that meets the basic requirements of the SCADA system. The developed system perfectly combines three-dimensional visualization and support of the GIS system. These implementations showed excellent results and feedback from users (with the test and final versions of the program).

Authors: Лебедев Леонид , Lebedev Leonid , Вирясов Михаил , Viryasov Mihail , Громов Владимир , Gromov Vladimir
Published: November 2019

The paper describes the intelligent format CIFc for compressed representation of color graphic images (GI). The proposed format is an extension of the effective IFc format, which is based on the correlation-extremal contour methods (CECM) of character-text information recognition. The technology for obtaining descriptions in CIFc format is based on the decomposition of the original GI with the selection of the text layer and the color layer. The text layer is represented by a black-and-white image obtained as a result of binarization of the bleached GI, and is a foreground mask. The color layer includes background and color information about the foreground mask and is compressed using wavelet transform. Compression of the text layer after its vectorization is carried out by the two-criteria KECM algorithm in the self-learning mode. Image restoration is carried out in reverse order on the basis of the restoration of each of the layers. A theoretical justification is given for the effectiveness of the representation of color GI in the proposed CIFc format in comparison with the closest analogue of DjVu. The theoretical justification of the effectiveness of the proposed CIFc format in comparison with the closest analogue of DjVu and the results of experiments on model and real color GI’s are given.

Authors: Рязанов С. , Ryazanov S. , Решетников Михаил , Reshetnikov Mihail
Published: November 2019

Existing mathematical models for calculating gearing are quite complex and do not always make it possible to quickly and accurately obtain the desired result. A simpler way to find a suitable gear option that satisfies the task is to use computer modeling and computer graphics methods, and in particular solid-state modeling algorithms. The use of geometric modeling techniques to simulate the process of shaping the working surface of gearing is based on the relative movement of intersecting objects in the form of a “workpiece-tool” system. This allows you to obtain the necessary geometric model that accurately reproduces the geometric configuration of the surfaces of the teeth of spatial gears, taking into account the technological features of their production on gear cutting machines. This information allows you to perform on the computer imitation control the movement of the cutting tool. Ultimately, this boils down to the problem of analytic description and computer representation of curves and surfaces in three-dimensional space. As the gear cutting tools, the most widely used are disk and worm modular mills (shaver), gear cutting heads, dolbyaki and lath tools. At the moment there are no computer algorithms for obtaining the “dolbyak” producing surfaces, which are obtained by a tool with a modified producing surface. A change in the geometric shape of the tool producing surface will lead to a change in its working surfaces, which may lead to an improvement in their contact. This article shows the application of the developed methods and algorithms of geometric and computer modeling, which are intended for shaping the working surfaces of the Dolbyak tool. Their application will speed up the process of calculating intermediate adjustments of machines used for cutting gears, bypassing complex mathematical calculations that, under conditions of aging of the gear-cutting machines, their wear and the inevitable reduction in the accuracy of their kinematic chains.

Published: November 2019

Rendering of large 3D scenes with a convincing level of realism is a challenging computer graphics problem. One of the common approaches to solving this problem is to use different levels of details (LOD) for scene objects, depending on their distance from the observer. Using hierarchical levels of detail (HLOD), when levels of details are created not for each object individually, but for large groups of objects at once, is more effective for large scenes. However, this method faces great challenges when changes occur in the scene. This paper discusses a specific class of scenes with a deterministic nature of events and introduces a method for effective rendering of such scenes based on usage of so-called hierarchical dynamic levels of details (HDLOD). Algorithms for generating HDLOD and their use for visualization of the scenes are also described.

Published: November 2019

The work is devoted to the problems of constructing a generalized computational experiment in the problems of computational aerodynamics. The construction of a generalized computational experiment is based on the possibility of carrying out parallel calculations of the same problem with different input data in multitasking mode. This allows carrying out parametric studies and solving problems of optimization analysis. The results of such an experiment are multidimensional arrays, for the study of which visual analytics methods should be used. The construction of a generalized experiment allows one to obtain dependences for valuable functionals on the determining parameters of the problem under consideration. The implementation of a generalized experiment allows one to obtain a solution for a class of problems in the ranges under consideration, and not just for one problem. Examples of constructing a generalized computational experiment for various classes of problems of computational aerodynamics are presented. The article also provides an example of constructing such an experiment for a comparative assessment of the accuracy of numerical methods.
Perceptually Motivated Method for Image Inpainting Comparison
Authors: Молодецких Иван , Molodetskikh Ivan , Ерофеев Михаил , Erofeev Mikhail , Ватолин Дмитрий , Vatolin Dmitriy
Published: November 2019

The field of automatic image inpainting has progressed rapidly in recent years, but no one has yet proposed a standard method of evaluating algorithms. This absence is due to the problem’s challenging nature: image-­inpainting algorithms strive for realism in the resulting images, but realism is a subjective concept intrinsic to human perception. Existing objective image-­quality metrics provide a poor approximation of what humans consider more or less realistic. To improve the situation and to better organize both prior and future research in this field, we conducted a subjective comparison of nine state-­of­-the­-art inpainting algorithms and propose objective quality metrics that exhibit high correlation with the results of our comparison.

In the present study, 45 patients with schizophrenia syndromes and 39 healthy subjects are studied with electroencephalogram (EEG) signals. The study groups were of different genders. For each of the two groups, the signals were analyzed using 16 EEG channels. Multiscale entropy, Lempel-Ziv complexity and Lyapunov exponent were used to study the chaotic signals. The data were compared for two groups of subjects. Entropy was compared for each of the 16 channels for all subjects. As a result, topographic images of brain areas were obtained, illustrating the entropy and complexity of Lempel-Ziv. Lempel-Ziv complexity was found to be more representative of the classification problem. The results will be useful for further development of EEG signal classification algorithms for machine learning. This study shows that EEG signals can be an effective tool for classifying participants with symptoms of schizophrenia and control group. It is suggested that this analysis may be an additional tool to help psychiatrists diagnose patients with schizophrenia.

Published: November 2019

To date, flying unmanned aerial vehicles (UAVs), with digital cameras on board, have become commonplace. The resulting images are collected in orthophotomaps and more used for visual analysis. A numerical analysis of the content of images is still poorly developed. One of the areas of analysis is the allocation of vegetation in the image and the determination of types. There are many ways to highlight plants in an image, such as texture, color, or index analysis. In this paper, we set the task of processing the image obtained from the UAV, isolating the vegetation in the image, selecting the desired plants from the set, and estimating the area occupied by this plant in the image based on texture analysis.

Processing and text mining are becoming increasingly possible thanks to the development of computer technology, as well as the development of artificial intelligence (machine learning). This article describes approaches to the analysis of texts in natural language using methods of morphological, syntactic and semantic analysis. Morphological and syntactic analysis of the text is carried out using the Pullenti system, which allows not only to normalize words, but also to distinguish named entities, their characteristics, and relationships between them. As a result, a semantic network of related named entities is built, such as people, positions, geographical names, business associations, documents, education, dates, etc. The word2vec technology is used to identify semantic patterns in the text based on the joint occurrence of terms. The possibility of joint use of the described technologies is being considered.

Published: November 2019

The object of the work is to compare and analyze external and internal exposure doses and assess damage to the population living around nuclear power plants with VVER-type reactors (on the Rostov and Kalinin nuclear power plants), within a certain radius, taking into account the wind rose. There will also be proposed measures for the possible addition and refinement of formulas. The method of calculating the doses of external and internal exposure, as well as damage to the population in the ring segment of rumba. External and internal exposure doses for Kalinin and Rostov NPPs have been considered. An assessment of material damage was conducted. A variant of the format of the atlas of risk assessments is proposed. Initial assumptions have been made regarding the discrepancy in the results obtained for both doses and damage. One of the possible reasons for the discrepancy in the results of calculating the dose and damage to the Kursk and Smolensk NPPs may be the difference in the terrain. We need to take this into account. By relief changes we mean not ravines and slopes, but hills, mountains, fields. Additionally, you can consider the type of terrain: steppes, forests, etc., although all this will contribute to the already quite a long distance from the nuclear power plant. In the future, it is planned to continue work on the atlas of risk assessments and think over its more convenient format.

Published: November 2019

This article reviews the problems of color saturation correction during dynamic range compression of images. Special attention is drawn to emulation of human vision and photo cameras effects during processing of the images which have very bright areas (with brightness more than an order of magnitude greater than average brightness of the rest of the image). A method of desaturation of the brightest parts of images is suggested. This method provides lowering of the color saturation of each pixel depending on the pixel brightness. The improved method lowers saturation only of the brightest parts of an image. The size of the desaturated part of the image should not exceed 25% of the size of an entire image.

Introducción: el tronco venoso gastrocólico, según lo descrito por Henle en 1868 se forma de la confluencia de las venas gastroepiploica derecha, cólica derecha y pancreático duodenal anteroinferior. Su localización y conocimiento anatómico es de importancia quirúrgica en la movilización duodeno pancreática y colo-epiploica. Material y métodos: se utilizaron 13 cadáveres formolados, adultos, de ambos sexos. Se registró: formación del tronco venoso gastrocólico, calibre de los afluentes y del tronco, distancias entre: cuello del páncreas y borde superior del duodeno III, vena mesentérica superior a duodeno II. Se topografió el tronco venoso en relación a las estructuras mencionadas. Se registró largo del tronco, distancia al borde superior del duodeno III y al borde inferior del cuello de Páncreas. Resultados: la conformación más frecuente fue por confluencia de las venas cólica derecha, gastroepiploica derecha y pancreático duodenal anteroinferior. El calibre medio del tronco venoso fue 5,65mm (3,3mm-10mm). La distancia media entre duodeno III y cuello de páncreas fue de 31,34mm (13,2mm-51mm). La distancia media entre vena mesentérica superior y duodeno II fue de 34,23mm (23,8mm-45,7mm). El largo medio del tronco venoso fue 9,43mm (3,2mm-16,3mm). Conclusión: se constató, en la mayoría de los casos, que la confluencia de formación del tronco venoso se daba según lo descrito clásicamente. Este se situó más frecuentemente de disposición oblicua hacia abajo y adentro, y en el cuadrante ínfero-interno respecto al cuadrilátero dado por una línea vertical desde cuello del páncreas a duodeno III y una horizontal desde duodeno II hasta la vena mesentérica superior.
HAS REFORM OF THE SYSTEM OF PUBLIC HEALTH INSURANCE FOR THE POOR IN INDONESIA INCREASED HEALTH INEQUALITY? CONSIDERING DIFFERENT ACCESSIBILITY OF PUSKESMAS
Authors: Rinasih Rinasih
Published: November 2019

Though the Indonesian government reformed its public health insurance system for the poor in 2008, the country still faces challenges with the disparity of accessibility to primary healthcare centres (puskesmas). This study examines whether the 2008 healthcare system reforms increased health inequality of the poor. Using data from the RAND Indonesian Family Life Survey (IFLS) and The Village Potential Statistics (PODES), this study found an indication that, in the aftermath of the reforms, the gap widened in the tendency for the poor to make insurance claims depending on their level of access to healthcare centres. Therefore, to protect the poor from catastrophic out-of-pocket expenditure, besides the provision of public health insurance, the government needs to be concerned about the accessibility of public health care, which includes not only the provision of direct healthcare infrastructure, but also improving road access conditions.

Impuesto a la Renta, progresividad y capacidad de pago, ¿Quién soporta la carga fiscal en Tungurahua?
Authors: Mera Bozano Fabián , Villacís Corella Mateo
Published: November 2019

Conforme el sistema tributario en el Ecuador el Impuesto a la Renta es un impuesto progresivo que recae directamente sobre la renta de los contribuyentes en función de su capacidad de pago, esto se refleja en la Provincia de Tungurahua donde el impuesto, cuyo número de declarantes ha sido creciente, recae en los ciudadanos de rentas altas, lo que permite una adecuada redistribución de la riqueza, sin afectar el derecho a la propiedad, con una tasa impositiva efectiva que se encuentra muy por debajo del promedio de América Latina, descartando la posibilidad de un impuesto confiscatorio, y que más bien da la posibilidad de reducir la contribución fiscal a través de la deducción de gastos personales dentro de la política de equidad tributaria.

Estimación de la función de utilidad del consumidor ecuatoriano en el año 2012
Authors: Cervantes Jiménez Miguel , León Castañeda Eduardo
Published: November 2019

El presente artículo genera tres funciones de utilidad del consumidor ecuatoriano en los ámbitos nacional, urbano y rural con base en una función de utilidad tipo Cobb-Douglas y datos de la Encuesta Nacional de Ingresos y Gastos de Hogares Urbanos y Rurales 2011-2012, cada una con doce bienes cuyos exponentes representan la proporción del gasto de cada bien respecto al gasto total. Los consumidores del Ecuador destinan la mitad de gasto en alimentos y bebidas no alcohólicas, transporte y otros bienes y servicios. El gasto destinado a los alimentos en las zonas urbanas y rurales es de 23 por ciento y 32 por ciento, respectivamente. El decil I destina el 60 por ciento de su ingreso a satisfacer estas necesidades, mientras que el decil X utiliza entre el 41 y el 50 por ciento de sus recursos, dependiendo de si habitan zonas urbanas o rurales, respectivamente. Las funciones de utilidad de los consumidores se pueden utilizar para analizar los efectos de la aplicación de políticas públicas como el establecimiento de precios controlados, subsidios o de cambios impositivos.
