PURPOSE: The aim of this study was to assess the anatomic, demographic, etiologic and clinical profile of patients presenting with uveitis at a tertiary care hospital. It was an observational study done with the aim of determining gender predilection and age group vulnerability of uveitis along with the types of uveitis and comparing infectious and non-infectious causes.
RESULTS: 36 patients of all age groups with uveitis were included in the study. Systemic and ocular examination was done, relevant investigations were performed. Mean age of patients studied was 34.92 ± 9.6 years with female predominance. Most common symptoms were ocular pain, redness followed by photophobia with 38.89% patients having recurrent symptoms. Most common type of uveitis was anterior uveitis followed by intermediate uveitis and posterior uveitis. Majority of patients had bilateral involvement. Some of the patients had associated co-morbidities like rheumatoid arthritis, diabetes, hypertension etc.
CONCLUSION: Identifying the cause of uveitis is required for appropriate treatment. Hence a multidisciplinary approach to the diagnosis and management of patients with uveitis between the ophthalmologist and a team of specialists in other areas of medicine is the need of the hour.

Objective. The goal of the study is to optimize a computer model of a Vivaldi antenna with conductive plates on the same side as the resonator.Method. The study is based on electrodynamic modeling methods.Result.The paper presents a computer model of a Vivaldi antenna with conductive plates on one side with a resonator. A comparative analysis of two types of Vivaldi antennas was carried out of the dependence of the beam width and the voltage standing wave ratio on the radius of the current-conducting plate curve in the form of lobes and the values of the opening in two planes θ = 900 (the plane of the antenna's opening) and φ = 00 (the plane perpendicular to the antenna's opening plane) in the frequency range from 3 to 24 GHz. The influence of the shape, size and position of the resonator on the SWR value and the width of the antenna radiation pattern was determined. VSWR values are given for different shapes and sizes of the resonator. The main parameters of the resonator have been identified, which affect the characteristics of the antenna.Conclusion.

Methods for assessing the connectivity of an undirected bipolar labeled graph taking into account the destructive impact of external threats on its vertices
Authors: Voevodin V. A. , Krahotin N. A. 
Published: April 2024

Objective. The main arguments that position the problem of assessing the connectivity of the bipolar graph in relation to the conditions of destructive impact of external threats (threats) as relevant for assessing the vitality of information systems (IS) are discussed operating under conditions of information security threats.Method. The following are presented: formulation of the problem of assessing connectivity for conditions of exposure to threats; a brief overview of existing methods for structural modeling of bipolar structures; results of the analysis of the applicability of existing methods for assessing the stability of functioning (stability) of bipolar structures in relation to conditions of exposure to threats. The initial conditions are accepted: the stability of the information system as a whole depends deterministically on the stability of its structural elements and the network structure itself; the problem of assessing the connectivity of a two-pole structure is basic for assessing the connectivity of the corresponding multi-pole structures; the stability analysis of the impacted object is carried out using minimax criteria, and the result is presented in the form of the minimum value of the stability function and the moment in time of the occurrence of this event.Result. Limiting factors that prevent the use of existing methods to solve the problem have been identified. The main limiting factor is that existing methods are based on probabilistic stationary models that require representative statistics. The second, no less important limiting factor is that the situation characterizing the impact of threats is very dynamic (not stationary), the events themselves are very rare, and the assessment period is comparable to the period of response to threats, which does not allow obtaining effective assessments of sustainability. It is proposed to: generalize existing methods for conditions of non-stationary functioning process, for which, when assessing, take into account changes in the probabilistic characteristics of nodal elements over time; as an indicator characterizing connectivity, use the minimum value of the stability function determined during the period of exposure to threats. The price to pay for ensuring the sustainability of the functioning of the affected object under the influence of threats is the need to ensure structural redundancy.Conclusion. The results of the study can be used by persons who simulate both the object of impact and the processes of its functioning, to make a decision on ensuring the continuity of production processes under the conditions of the impact of threats.

Objective. The purpose of the work is to apply mathematical modeling methods to solve problems of ensuring road safety on highways.Method. Quantitative methods for analyzing road safety problems (BDD) are based on probability theory, mathematical statistics, information theory, multifactor analysis, reliability theory, modeling, programming and other mathematical methods.Result. The main trends in the study of road safety problems are considered. It is indicated that the mathematical dependences of the influence of a limited number of factors are unsuitable for a satisfactory description of the “driver-vehicle-road-environment” (VADS) system as a whole. Paying attention to the uncertainty of objects, properties and connections of the VADS system, the need to use a systematic approach in solving these problems is justified. The need to take into account regional conditions in road safety is discussed. Mathematical models recommended for solving problems of ensuring road safety are presented.Conclusion. Generalization, systematization of the vast empirical material of road accidents accumulated as a result of specific studies taking into account economic, social and demographic conditions and the development of theoretical concepts based on system representations are the most important conditions for solving the problems of ensuring road safety.

Inequalities in Transition to Homeownership in Household Life Cycle
Authors: Matel Anna 
Published: April 2024

Abstract
The housing situation changes with the household formation cycle. Age, marital status and having children are key to explaining the tenure status of households. However, the question of what factors differentiate owners and tenants if they are at the same stage of household formation arises. Using the logit model method, the determinants of tenure status of Polish households in the same life cycle stages were compared. The study used EU-SILC data for 2018. It showed that both the determinants of housing choices and the strength of their impact differ. At the household formation stage, income and the size of the city are important determinants. At this stage, housing choice is limited due to the availability of the rental market and the need for young people, who migrate to larger cities, to become independent. At the stabilization stage, the source of inequality was the gender of the household head, education, health and marital status. It has been observed that entering into an informal relationship by divorced persons does not equalize their chances of homeownership.
