The problem that is being solved in the research is to increase the efficiency of decision-making in management tasks while ensuring the given reliability, regardless of the hierarchical nature of the object. The object of research is the decision-making support systems. The subject of the research is the decision-making process in management tasks using an improved cat flock algorithm. The research hypothesis is the possibility of increasing the efficiency of decision-making with a given assessment reliability. In the course of the research, an improved method of parametric optimization based on the improved algorithm of the cat flock was proposed. In the course of the research, the general provisions of the theory of artificial intelligence were used to solve the problem of analyzing the state of objects and subsequent parametric management in intelligent decision-making support systems.
The essence of the method improvement lies in the use of the following procedures, which improve basic procedures of the cat flock algorithm, namely, search and chase:
– training of individuals of a cat flock with the help of evolving artificial neural networks;
– taking into account the type of uncertainty of the initial data while constructing the metric of the path of the cat flock, which reduces the time of searching for the optimal solution;
– searching for a solution in several directions using individuals from the cat flock, which reduces the time of searching for the optimal solution;
– initial display of individuals from the cat flock not randomly;
– additional consideration of the chase parameter, which limits the chase area, which allows to take into account the priority of the search;
– the ability to determine the need to involve additional network hardware resources.
An example of the use of the proposed method is presented on the example of assessing the state of the operational situation of a group of troops (forces). The specified example showed a 17–23 % increase in the efficiency of data processing due to the use of additional improved procedures

The object of this study is an approach to solving the problems of designing service-oriented networks that warn about emergencies using dynamic programming. The main issue is the complexity of algorithmization of processes that describe the achievement of an optimal solution in multi-stage nonlinear problems. The possibilities of applying the Bellman optimality principle for solving the set tasks for the purpose of their application in the field of engineering and technology are determined. Based on the Bellman functional equation, a model of the optimal number of sensors in the monitoring system for warning of emergencies was built.
A feature of the design is that using the classical Bellman equation, it is proposed to solve problems of various technical directions, provided that the resource determines what exactly makes it possible to optimize work in any way. Important with this approach is the planning of the action as an element of some problem with the augmented state. After that, the proposed structure in formal form extends to other objects.
A problem was proposed and considered, which confirmed the mathematical calculations, as a result of which an optimal plan for replacing the sensors of the system was obtained; and the possibilities of significant cost reduction were identified. In the considered example, an optimal plan for replacing the system sensors was compiled and the possibility of reducing costs by 31.9 % was proved.
The proposed option was used in the development of information technology for modeling a service-oriented network based on energy-efficient long-range protocols; some of the identified features were further developed in the design of a recommendation system for issuing loans and developing an interactive personnel training system

The object of this study is the production technology of bread with pumpkin paste. The task to enrich bread with pumpkin paste was resolved.
The influence of different amounts of pumpkin paste on the technological parameters of the quality of wheat bread and culinary quality was investigated. It was established that the addition of pumpkin paste influenced the technological parameters of the quality of bread. Bread baking loss decreased from 10.8 % to 9.9 with the addition of 5 % pumpkin paste. In the variant with 60 % pumpkin paste, the bread baking loss was 3.8 %. With the addition of 5–25 % of pumpkin paste to the bread recipe, bread shrinkage increased significantly to 4.2–4.3 % compared to control (3.5 %). A significantly larger volume was obtained by adding 25–30 % pumpkin paste. With this amount of paste, this indicator was 207–211 cm3/100 g of dough and 346–348 cm3/100 g of flour. With the addition of 35–60 % of pumpkin paste, the volume of bread was 330–338 cm3/100 g of flour. A significantly higher specific volume was obtained by adding 25–30 % of pumpkin paste – 2.0 cm3/g of dough and 2.3–2.4 cm3/g of bread. The addition of pumpkin paste increased the mass of bread from 133 to 135–166 g.
It was established that the organoleptic assessment of bread did not change from the amount of pumpkin paste. The smell, taste, pores in size and uniformity correspond to the highest level of assessment – 9 points. The elasticity and consistency of the crumb was at the level of 7 points. The surface of the crust corresponded to 3 points, the glossy surface – 3 points.
A distinctive feature of the research results is that in the technology of bread it is necessary to add 25–30 % of pumpkin paste. The use of this amount of pumpkin paste provides bread with a volume of 346–348 cm3/100 g of flour. The smell and taste of bread according to this recipe is high – 9 points.
The recommendations reported here can be used by small and medium size enterprises for the production of bakery

The aim of the work was to create an approach for the development of HPLC methods for the determination of meldonium in dosage forms with the usage of salts of chaotropic anions in mobile phases.
Material and methods. Analytical equipment: Shimadzu UPLC system LC-40 PDA; Shimadzu Nexera-i LC-2040C 3D-Plus, controlled by software Lab Solution version 5.97, electronic laboratory balance RAD WAG AS 200/C, pH-meter I-160MI. Meldonium dihydrate (purity 99.3 %) was purchased from Sigma-Aldrich (Switzerland), and Vasopro capsules 500 mg were purchased from a local pharmacy. Chromatographic conditions: Agilent Zorbax C-18 SB 150 mm x 4.6 mm 3.5 μm column was used (Agilent Technologies, USA). Mobile phases: 1) 0.25 % KPF6 w/v – 0.1 % v/v 85 %H3PO4 95 % – 5 % ACN, 2) 0.3 % bis-(trifluoromethane)sulfonimide lithium salt 97 % w/v – 0.1 %v/v 85 % H3PO4 80 % – 20 % acetonitrile. Flow rate - 1mL/min, T=32 °C, detection UV=at 4 channels - 190 nm, 195 nm, 200 nm, 205 nm.
Results and discussion. We have proposed two approaches using two different salts of chaotropic anions - potassium hexafluorophosphate and bis-(trifluoromethane)sulfonimide lithium salt – for the HPLC method development. The chaotropic effects of these anions toward meldonium strongly influenced the analyte migratory behaviour. Both mobile phases involved, in addition to the use of a chaotrope, also the use of acetonitrile and pH adjustment with 0.1 % v/v 85 % H3PO4 solution. The detection wavelength (190 nm, 195 nm, 200 nm, 205 nm) was selected experimentally. The results were obtained for 8 concepts. Parameters of the chromatographic system confirm the conclusions and results of this investigation for the influence of chaotropic salts on N-containing molecules in an acidic pH medium, by increasing their retentivity and improving peak shape and uniformity homogeneity, even on the column without end-capping and base-deactivating. Validation of the analytical method was carried out following the requirements of SPhU. Conclusions. HPLC methods for the determination of meldonium in dosage forms have been developed, using positive impacts of chaotropic salts on the molecules containing N-atoms in their molecule on their retentions and peak symmetries on the chromatogram. The validation of the analytical methods showed their suitability for pharmaceutical analysis

Context. The proposed article relates to the field of visual information processing in a computer environment, more precisely to the determination the parameters of the interest object in the image, in particular, the contour of the interest object In most cases, the contour of an object is a simply connected sequence of curve arcs.
Objective. The purpose and subject of the study is to find and to propose such a definition of the digital curve arc, as the most important element of the object contour in the recognizable image, which does not contradict modern neurophysiological conceptions about visual perception, and to recognize the object contour as a sequence of the digital curve arcs.
Method. The representation of the image in the form of a structural model is used, one of the structural elements of which is the contour of the object, consisting of digital curve arcs. Also, the image is considered as a cellular complex which corresponds to modern ideas about human visual perception.
Results. The new definition for arc of a digital curve as a sequence of digital straight segments is proposed, which does not contradict to modern concepts of neurophysiology. In contrast to the known definitions of a curve arc, the proposed definition of a digital curve arc makes it possible to determine the start and end points of the arc. According to the description of the contour of an object as a simply connected closed sequence of line segments, it is proposed to construct a description of the contour as a sequence of arcs of digital curves.
Conclusions. The use of the proposed definition of the digital curve arc in image processing makes it possible to recognize the contour of an object in an image and present it in a form close to visual perception. For best results, the use of variable resolution in image processing algorithms is recommended.

El objetivo principal de la investigación, a partir de la cual se genera este artículo, fue identifcar los estilos de vida y hábitos alimentarios entre adultos jóvenes de 25 a 30 años de edad, mediante un estudio comparativo con las poblaciones ubicadas en la ciudad de Pasto (Nariño) y en Pitalito (Huila).
La investigación se basó en el paradigma cuantitativo, utilizando técnicas que involucraron directamente al individuo y al fenómeno a investigar, logrando así adquirir factores precisos que se pudieran medir. Se abordó con enfoque descriptivo correlacional lo que permitió comparar los resultados en las dos ciudades; además, se realizó mediante un diseño transversal, teniendo en cuenta a su vez el aspecto correlacional, puesto que la encuesta se aplicó a la población y posteriormente se llevó a cabo una descripción de los resultados en relación con las diversas variables y la teoría.
Entre los rasgos relevantes del grupo objeto de estudio están el grado de escolaridad, dado que una parte considerable de la población tenía nivel profesional, y el estado civil, puesto que en gran porcentaje resultaron ser solteros. Por otra parte, para la obtención de datos se utilizaron instrumentos como el Cuestionario de Perfl Estilo de Vida [PEPS-I], el Cuestionario Internacional de Actividad Física [IPAQ] y el Cuestionario de Frecuencia de Ingesta de Alimentos [CFIA].
En cuanto a los datos recolectados del estilo de vida, se evidencia que mantienen la califcación positiva, teniendo en cuenta que se evaluaron aspectos de nutrición, ejercicio, niveles de actividad física, manejo del estrés, autoactualización y soporte interpersonal, en este último aspecto se encuentra una diferencia entre las dos regiones; paralelamente a ello se recolectó información sobre los hábitos alimentarios, donde se reﬂeja mínimamente la diferencia en el consumo de algunos alimentos entre las dos zonas.
Se concluyó que los grupos estudiados en los dos municipios presentan grandes diferencias en cuanto a estilos de vida y hábitos alimentarios, siendo inﬂuenciados por aspectos como las condiciones geográfcas (clima, población total), condiciones de vida, escolaridad y el estrato socioeconómico.

Many countries were affected by the appearance of SARS-COV-2 that was spreading rapidly, causing damage to humanity and causing a global crisis, this generated a generalized quarantine to avoid the physical approaches recommended by the health system, affecting all students in the world, since it was wanted to avoid forming foci of contagion in educational centers, for this reason, some automated systems that are marketed in the markets were applied to combat the pandemic in educational centers, but they are inefficient when registering the work attendance of teachers, causing loss of time in the registration process and causing an agglomeration of people due to the failure in the registration process, in addition to not allowing to manage the reports of the teacher's work attendance. In view of this problem, in this article the management of an automatic system was carried out to generate reports on the attendance control of the teaching staff in the educational center and control the working hours of each teacher to be visualized through a user interface, being able to control the labor discipline of each teacher since all the records will be stored in a database. Through the development of the system, it was observed that the system works effectively since an efficiency of 98.87% was obtained in its operation to control the time of entry and exit of each teacher, being an accepted value since the process is conducted safely.

Diagnosis of initial epithelial pathology maybe difficult in Oral Squamous Cell Carcinoma (OSCC), early invasive squamous cell carcinoma and other atypical epithelial malignancies, under routine Haematoxylin and Eosin (H and E) stain. In this context, an appropriate differential stain capable of distinguishing epithelial cells in the connective tissue may well prove to be a valuable aid. In the present study, we endeavor to use Modified Cajal's trichrome stain for making diagnosis easier without resorting to expensive diagnostic aids. Aim of present study is to assess both the epithelial and connective tissue elements in early invasive carcinoma, verrucous carcinoma and oral squamous cell carcinoma in tissue sections stained with modified Cajal's trichrome stain (MCTS) and to compare it with H and E-stained sections. Formalin-fixed, paraffin-embedded tissue blocks of early invasive SCC (n = 10) Verrucous carcinoma (n = 10) OSCC (n = 10) were stained with MCTS and H&E. The sections were compared based on set histopathological criteria. In SCC cases stained with MCTS, invasion into connective tissue and keratin pearls were strikingly evident. Depth of invasion could be more accurately determined. Thus, CTS is a good differential stain, clearly delineating the epithelial elements from the connective tissue elements visually.

Mucormycosis is a rare fungal infection with high morbidity and mortality rate as compare to its prognosis which is poor. Coronavirus disease 2019 (COVID-19) infection may be associated with a wide range of bacterial and fungal co-infections. We report the case of a patient with COVID-19 infection, which, during the course of the treatment, developed rhino-orbital mucormycosis. Very few cases of mucormycosis of mandible have been reported in literature. In this article, we present three cases of mucormycosis affecting mandible and the surgical management for it given in our institute. Extraction of all mobile teeth was done along with mechaincal curettage and sequestrectomy performed.Patients are kept in regular follow up and referred to Prosthodontics department for rehabilitation.COVID-19 associated mucormycosis is aggressive and locally invasive, therefore early diagnosis and management is imperative to improve prognosis and help reduce morbidity. Mandible is not affected frequently by mucormycosis but is aggressive. Caution before attempting dental extraction which can worsen ongoing infection will ensure good outcomes, shorter hospital stay and better rehabilitation.
