Published: December 2022

Introduction: Hospital atmosphere and managerial support during the COVID-19 pandemic are important factors in determining the quality of nursing care, however, support that is not provided properly can cause work stress, causing burnout syndrome which results in low quality of work. The purpose of this study was to explain the relationship between managerial support and hospital atmosphere with burnout syndrome of nurses at COVID-19 unit. Methods: The research design was correlational descriptive with a cross-sectional approach. A total of 64 nurses at COVID-19 unit at the referral hospital for COVID-19 patients in Surabaya who handle COVID-19 patients directly for at least 2 months and treat COVID-19 patients at least 1-2 patients every day in the isolation room were selected through a simple random sampling method. The variables in this study were managerial support, hospital atmosphere, and burnout syndrome. Perceived managerial support was measured by the Managerial Support Questionnaire, the Hospital Atmosphere Questionnaire for perceived hospital atmosphere, and the Maslach Burnout Inventory to measure burnout syndrome. The results were analyzed by descriptive analysis and logistic regression test with a significance value of p≤ 0.05. Results: The results showed that there was a significant relationship between managerial support (p = 0.027) and hospital atmosphere (p = 0.026) with burnout syndrome. The relationship between managerial support and hospital atmosphere is negative. The higher the managerial support and hospital atmosphere, the lower the burnout syndrome level. Conclusion: High managerial support and a good hospital atmosphere can reduce burnout syndrome among nurses at COVID-19 unit. The results of this study are expected to be a reference for hospitals in preventing nurse burnout syndrome so that the quality of service increases.

Published: December 2022

The area of the study is located in northern Iraq on the western side opposite the confluence of the Tigris River with the upper Zab tributary, about 45 km southeast of the city of Mosul within the Hamrin-Makhoul zone belonging to the foothills zone within the unstable area. The area contains rocks of many formations ranging in age from the Lower Miocene to the Quaternary, and includes the formations of the Euphrates, Fatha, and Quaternary deposits. Sulfur deposits are present in the Fatha formation within the productive bed which contains three major sulfur-bearing horizons or zones separated by several heterogeneous layers of marly claystone and dolomite limestone of different thicknesses. The formation of sulfur due to the processes of reducing gypsum or anhydrite with the availability of hydrocarbons and the action of anaerobic bacteria, where hydrogen sulfide gas H2S is produced, which is later oxidized by groundwater, forming sulfur ore with the help of other factors represented by tectonic and hydrogeological factors.
The mineral reserves of sulfur deposits were recalculated and estimated using the geostatistical method, as it is one of the modern applications adopted in the Rockwork-14 program, which takes into account the location of each model in relation to the other within the mineral deposits extensions and even outside the boundaries of those extensions, which gives high accuracy and reliability about the amount of reserves depending on the group Among the important criteria, such as thickness, concentration of the ore, and density, the reserve of sulfur in the Mishraq sulfur field-1 was estimated at 121,230,554,68 tons.
The validity and suitability of using the open mine method for extracting sulfur in the study area was discussed based on a decisive and important factor, which is the stripping ratio, which determines the type of appropriate extractive method, and it was equal to 6 for the entire study area, a large value that exceeded the maximum permissible limit of 5. This method is not economically feasible due to the high extractive cost and the presence of sulfur at different depths ranging between 80-230 m as well as the presence of environmental and geological problems that hinder the use of this method in sulfur extraction.
The study was based on the data obtained for a group of (9) exploratory wells that were drilled in the region.

Published: December 2022

Un análisis de cadena de valor de la pesquería de arrastre en el Pacífico mostró que más del 50 % de los empleos generados en esta pesquería son ocupados por mujeres, y que la mitad de estos son aportados por las platoneras del distrito de Buenaventura. Las platoneras son mujeres afrodescendientes comercializadoras de productos pesqueros basados en las capturas incidentales de esta pesquería y que hacen parte integral de la pesquería de arrastre. Desconociéndose el aporte a la economía local y al sector pesquero, este estudio describe el rol de las platoneras en la pesquería para realizar un mapeo de la cadena de valor sensible al género y nutrición. Para esto, se aplicaron entrevistas a 123 platoneras en cinco puntos de comercialización del distrito. El análisis mostró que ellas perciben en promedio $87.500 COP diarios. La edad promedio es de 50 años y 94 % se encuentran afiliadas al sistema de salud bajo régimen subsidiado. Las platoneras comercializan alrededor de 60 productos y su papel es clave para el dinamismo del sector pesquero, la economía y la tradición gastronómica local.

В статье описаны результаты разработки алгоритма обнаружения аномалий временных рядов с учетом особенностей предметной области. Алгоритм предполагает нахождение прогноза временных рядов с использованием LSTM-сетей, обнаружение аномалий по полученному прогнозу, фильтрацию найденных аномалий в соответствии с возможными отклонениями значений временного ряда от тренда, отраженными в онтологии, и логический вывод результатов поиска с использованием набора SWRL-правил. Эффективность предложенного подхода подтверждена рядом экспериментов, проводимом на бенчмарке данных по работе нефтяных вышек.
The paper describes the results of the development of an algorithm for detecting anomalies in time series, taking into account the specifics of the subject area. The algorithm involves finding a time series forecast using LSTM networks, detecting anomalies based on the obtained forecast, filtering the found anomalies in accordance with possible deviations of the time series values from the trend reflected in the ontology, and logically deriving search results using a set of SWRL rules. The effectiveness of the proposed approach has been confirmed by a number of experiments conducted on the benchmark of data on the operation of oil rigs.

Authors: Фридман Александр Яковлевич 
Published: December 2022

В настоящей работе предлагается метод ситуационного моделирования промышленно-природных комплексов (ППК) на различных уровнях управления их безопасностью: от решения вопросов стратегического развития систем регионального масштаба и выше до оперативного управления структурой специализированных ППК при необходимости многократного принятия решений на ограниченном наборе известных альтернатив. Метод обеспечивает интеллектуализированную расчетно-логическую обработку информации о разнотипных характеристиках подобных комплексов с возможностью их анализа и сравнения в статике и динамике. Актуальность работы определяется усложнением ППК в современном мире и усилением их влияния друг на друга, а с другой стороны - появлением больших объемов дополнительных сведений о поведении ППК в связи с ускоряющимся развитием Интернета вещей. Новизна подхода заключается в унификации применения инструментов исследования сложных нестационарных структур в рамках причинно-следственной парадигмы, а также в ориентации на применение экспертных знаний для постановки и решения задач многокритериального сопоставления и выбора предпочтительных вариантов структуры ППК. Полученные альтернативы при необходимости можно дополнительно исследовать их имитацией с использованием специализированных для решения задач безопасности цифровых двойников компонентов ППК.
This paper proposes a method for situational modeling of industrial-natural complexes (INCs) at various levels of their safety management: from solving issues of strategic development for systems of a regional scale and above to operative control of the structure for specialized INCs when multiple decision-making is required on a limited set of known alternatives. The method provides an intellectualized computational-logical processing of information regarding different types of characteristics of such complexes with the possibility of their analysis and comparison in statics and dynamics. The relevance of the work is determined by the complication of INCs in the modern world with the resulted strengthening of their influence on each other, and on the other hand, by the emergence of large amounts of additional information about the behavior of INCs in connection with the accelerating development of the Internet of Things. The novelty of the proposed approach lies in unification of using tools for studying complex non-stationary structures within the framework of the cause-and-effect paradigm, as well as in focusing on applying expert knowledge for setting and solving problems of multi-criteria comparison and selection of preferred options for the structure of an INC. The resulting alternatives, if necessary, can be further investigated in more detail by their imitation with using digital twins of INC’s components specialized for solving safety problems.

Authors: Малышкин Юрий Андреевич 
Published: December 2022

В статье исследуется ассимптотическое поведение числа максимальных деревьев в модели графов равномерного присоединения. В предлагаемой модели рассматривается последовательность графов, которая строится по следующему реккурсивному правилу. Мы начинаем построение с полного графа на $m+1$ вершине, $m>1$. Затем на $n+1$-ом шаге мы добавляем вершину $n+1$ и проводим из нее $m$ ребер в разные вершины, выбранные равномерно из вершин $1,\ldots,n$. В статье получен результат о скорости сходимости числа максимальных деревьев в указанной модели с помощью стохастической аппроксимации.
We study the asymptotic behavior of the number of maximal trees in a uniform attachment model. In our model, we consider a sequence of graphs built by the following recursive rule. We start with the complete graph on $m+1$ vertices, $m>1$. Then on the $n+1$ step, we add vertex $n+1$ and draw $m$ edges from it to different vertices, chosen uniformly from $1,\ldots,n$. We prove the convergence speed for the number of maximal trees in such a model using the stochastic approximation technique.

В работе рассмотрено асимптотическое поведение резерва организации, подверженной риску в случае, когда число факторов, приводящих к убытку, случайно. Помимо новых результатов работа содержит обзор последних результатов автора, касающихся асимптотического поведения резервов страховых компаний. Проведено асимптотическое сравнение деятельности таких организаций в терминах необходимого добавочного числа таких факторов. Рассмотрены два примера, иллюстрирующие полученные результаты. Первый пример касается сумм независимых случайных величин, а во втором рассматривается трёхточечное симметричное распределение и распределение Пуассона.
The paper considers the asymptotic behavior of the reserve of an organization exposed to risk in the case when the number of factors leading to a loss is random. In addition to the new results, the paper contains an overview of the author's recent results concerning the asymptotic behavior of insurance company reserves. An asymptotic comparison of the activities of such organizations is carried out in terms of the necessary additional number of such factors. Two examples illustrating the obtained results are considered. The first example concerns sums of independent random variables, and the second one deals with a three-point symmetric distribution and a Poisson distribution.
