Authors: Rianto Adita , Pratama Ahmad Rafie
Published: November 2021

COVID-19 was declared a pandemic by the World Health Organization (WHO) due to the virus's uncontrolled spread around the world, including in Indonesia. The Indonesian government has made a number of steps to stop COVID-19 from spreading, one of which is COVID-19 vaccinations. However, not everyone thinks the vaccination is a good idea. Just like in many other countries, Indonesian people responded in different ways to COVID-19 vaccination posts on social media, be it from government officials/agencies or news portals. Their responses can be used to help the government decide on a better vaccination strategy that will help minimize the virus spread and end the pandemic in Indonesia. Using the lexicon method in determining the content sentiment in COVID-19 vaccination posts on Facebook, this research found that unlike news portals that tend to post a more balanced content (36% positive, 20% negative, and 44% neutral out of 23,623 posts with min score = -19, max score = 24, mean score = 0.25, and SD = = 1.43), government accounts posted much more positive content, both in terms of quality (min score = -15, max score = 40, mean score = 4.16, SD = 6.76 ) and quantity (69% classified as positive) than they did the neutral (15%) and the negative content (16%) out of 723 posts. Subsequent analysis with Two-Way ANOVA tests discovered that COVID-19 vaccination posts by the news portal accounts can elicit more varied reactions from the public than government accounts that tended to elicit only positive reactions. It is also confirmed that both the content sentiment of COVID-19 vaccination posts in Indonesia and the account types making the posts as well as their interaction terms do have an impact on how the public responses to them.

Un regard sur l’histoire des médecins scolaires (MS) montre que leur activité a toujours été étroitement liée aux conditions de vie et à la situation sanitaire des enfants, adolescent-e-s, leurs familles et leur entourage. Les MS travaillaient en réseau avec les institutions dans lesquelles se trouvent les enfants et qui agissent autour de l’enfant, et ils entretenaient le contact avec les groupes marginaux. Il s’agissait en première ligne de rattraper celles et ceux qui tombaient entre les mailles du système; cela pour permettre, au moyen d’une approche à bas seuil et si nécessaire active, l’accès aux soins et à la prévention à toutes et tous, indépendamment du statut social.
NEGARA KESEJAHTERAAN (WELFARE STATE) DALAM KONTEKS KEBIJAKAN POLITIK EKONOMI ISLAM DI INDONESIA
Authors: Jamil Irpan
Published: November 2021

ABSTRAKDalam konteks keislaman, Islam adalah ajaran yang komprehensif yang didalamnya memiliki konsep negara, pemerintahan, kesejahteraan ekonomi dan lain-lain. Dalam pandangan Islam, negara tidak bisa lepas dari konsep kolektif yang didalamnya termasuk landasan moral dan syariah Islam. Dalam konteks sekarang, negara kesejahteraan (Welfare State) merupakan sesuatu yang sangat penting dan mempunyai nilai yang strategis, mengingat bahwa negara kesejahteraan dianggap sebagai salah satu  jawaban yang paling tepat atas bentuk keterlibatan negara dalam mengubah kesejahteraan rakyat. Dalam konteks keindonesiaan cita-cita mewujudkan negara kesejahteraan sudah direncanakan jauh sejak negara ini didirikan, walaupun dalam perjalanannya menemui banyak permasalahan dan tantangan, bahkan ketika upaya-upaya yang berkaitan dengan perangkat untuk menuju konsep tersebut sudah tersedia termasuk didalamnya aturan-aturan yang telah disusun dalam bentuk perundangan ataupun kebijakan politik. ABSTRACTIn the context of Islam, Islam is a comprehensive teaching which includes the concept of the state, government, economic welfare and others. In the view of Islam, the state cannot be separated from the collective concept which includes the moral foundation and Islamic sharia. In the current context, the welfare state is something that is very important and has strategic value, considering that the welfare state is considered as one of the most appropriate answers to the form of state involvement in changing people's welfare. In the Indonesian context, the ideals of realizing a welfare state have been planned long since this country was founded, although along the way it encounters many problems and challenges, even when efforts related to the tools to achieve this concept are already in place, including the rules that have been compiled in form of legislation or political policy.

Published: November 2021

The article presents an analysis of the long-term dynamics of the hydrochemical conditions of the water of the Shershnevsky reservoir for 1972-2020 during the spring flood and summer low water. The features of the development of water quality indicators over time are determined: pH, mineralization, turbidity, color, suspended solids, the content of dissolved oxygen and organic substances by permanganate oxidability and BPK5, as well as changes in the concentrations of ammonium, nitrite, nitrate nitrogen and phosphates. In the water of the Shershnevsky reservoir for the period 1972-2020, trends of a significant decrease in mineralization, turbidity and permanganate oxidability were noted in both phases of the hydrological mode. In the summer low water period, a significant increase in chromaticity, oxygen content in water and orthophosphates was detected.. The revealed features of changes in the hydrochemical regime indicate an increase in the processes of anthropogenic eutrophication of the Shershnevsky reservoir – the only drinking source of the Chelyabinsk agglomeration and make it possible to predict the state of the aquatic ecosystem. The information obtained can be implemented in the process of making management decisions on environmental protection measures for the Shershnevsky reservoir.

Published: November 2021

Investigation and choice of an effective sorbent are significant for protection of water bodies against boron The boron high concentration in natural waters produces toxic impact on aquatic biota due to its high biological activity. This paper studied the dynamics of boric acid sorption from aqueous solutions by polycondensation anionite SB-1 synthesized on the base of monoethanolamine and epichlorohydrin. The anion exchanger contained aminooxyethyl and alcohol functional groups in its structure. Methods. It has been established the influences of the ion form of the anionite on the dynamic characteristics of boron sorption from both a model boric acid aqueous solution (0.43 mol/dm3) and an industrial wastewater effluent after boric acid production (0.47 mol/dm3), other things being equal (pH = 5.0; the volume rate of the solution passing through the anionite layer = 1.5 ml/min∙cm2; t = 20 0C). Structural studies to determine the form of boron in the anionite phase were performed using the IR spectroscopic method. Dynamic characteristics of boron sorption (the cation and overall ion-exchange capacity values, period of the protecting effect of the filter) were determined graphically from the sorption curves. Results. It has been found that the hydroxyl form of the anion exchanger SB-1, in comparison with the chlorine form, performs superequivalent boron sorption while boron sorption from both a model and real production solutions. For the first time we have demonstrated that at the initial stage, boric acid sorption is carried out owing to the chemisorption, resulting to the formation of stable hydroxoborate forms [B(OH)4]– in the ionite phase. As the anionite is being saturated and the concentration of free functional hydroxyl groups is decreasing, the formation of polynuclear forms of boric acid [B4O5(OH)4]2– occurs in the anionite phase by sorption of boric acid molecules on free tetrahydroxoborate anions and, further, the complex formation of polynuclear forms of boron by the nitrogen atom of aminooxyethyl functional groups. It has been stated that desorption of boron from anionite is considered to be effective when carried out with a 2 n. NaOH solution with a regeneration degree of 0.995.

Despite development of central water supply systems, springs still remain to be important sources of drinking water. In this work, the study of water quality in springs of Yekaterinburg city and its settlements was performed with the attention to radiological factor. Activity concentrations of radium-226 were determined in water of 20 springs. Methods. Determination of the radon-222 activities of was performed using gamma-spectrometry vis the equilibrium bismuth-214 gamma line. To determine radium-226, 5-liter water samples were taken, the radium was preconcentrated on a T-5 sorbent; then radium was separated on a thinlayer MnO2-PE sorbent followed by measurement on an alpha spectrometer. Results. In the vast majority of cases, activity concentrations of radium-226 were lower than the detection limit (0.3 Bq/L); the maximal activity concentration of 1.03 ± 0.27 was found that corresponded to the internal dose of 0.21 ± 0.05 μSv/y due to daily consumption of this water. No correlations were found between content of radium-226 and concentrations of radon-222, uranium-238 and alkaline earth ions. At the period of 09.2020 – 06.2021, monitoring of radon activity was performed in seven springs with previously found high radon content. Significant seasonal variations of radon activity were found; for some springs the difference between the minimal and the maximal activity reached 3. In the most cases, increase of radon activity occurred in water during winter that can be explained by both an increase of radon solubility in cold water and a decrease of flowrate.

Recently, the problem of creating new types of storage devices having non-volatile memory and commensurate in speed and number of rewriting cycles with operational storage is getting more relevant. However, microminiaturization of most known devices of this kind appears to have already reached scaling limits. In this regard, many computer developers have become involved in the development of low-power processors based on nanoelectromechanical relay elements. The article proposes nanorelay and logical elements based on graphene and hexagonal boron nitride having piezoelectric properties. It describes their design features, working principles and expected characteristics are described. It is noted that for the successful practical implementation of the proposed idea it is advisable to carry out additional works on synthesis of new two-dimensional piezoelectric and electroconductive nanostructures, which allow to reduce control voltage and the distance between relay contacts even in the off state.

The article discusses the determination of navigational data corruption, which received by the satellite navigation system as well as traffic control of ground mobile robots. It also specifies the movement features of ground robots, which affect the data integrity monitoring. It proposes an algorithm of control to implement the methods of autonomous onboard monitoring of the navigational data integrity. The algorithm is based on the equations of signal correspondence in various parts of the control system. It is designed to determine the inoperability of the satellite navigation system that implies the loss of signal and failure in the navigation problem solution. The algorithm takes into account the non-deterministic nature of moving ground robot with possible stops in the process of following the trajectory. The article considers the implementation variants of algorithm to assess reliability for the control system containing additional sensors of the robot’s displacement and for the hardware-redundant system containing no additional sensors. The results of modeling the movement of a ground mobile robot along an arbitrary trajectory in case of navigational data corruption are presented. The features of algorithm based on the simulation results are described in the article. The authors considered variants of robot control in case of navigational data corruption. The structure of the system and a method for controlling a mobile robot in case of satellite navigation system failures are also proposed. The method is based on the control mode in the system, according to the measured data of the position of the robot in the case of navigational data corruption or otherwise according to the data calculated from the robot model. The implementation of the method makes it possible to avoid significant deviations of the robot from a given trajectory of movement at intervals of signal loss of the satellite navigation system.

Generally, this is the experience of production workers, economists, designers, etc. that used to get a preliminary assessment of feasibility of hardware manufacturing at an enterprise. For a preliminary assessment, it is enough to understand the complexity of the product and available analogues. At the same time, it is not always possible to calculate an accurate production time for the product due to the lack of a complete set of design and technological documentation. The article presents an approach to calculating the production time of hardware using neural networks based on existing data for previous periods and types of hardware using. This approach allows estimating the production time without using accurate data on the design and manufacturing technology. The article also describes the structure of neural networks and defines the training sample. Some experiments were conducted based on the sample data, which allowed determining the initial weight coefficients of the neural network. The software implementation is made in the form of an additional module for an interactive web resource and uses T-SQL.

Nowadays image processing problems are becoming increasingly important due to development of the aerospace Earth monitoring systems, radio and sonar systems, medical devices for early diagnosis, etc. However, the most of the image processing works deals with images defined on rectangular two-dimensional grids or grids of higher dimension. In some practical situations images are set on a cylinder, for example images of pipeline sections, blood vessels, rotary parts, etc. The peculiarity of the domain for specifying such images requires its consideration in their models and processing algorithms. The article deals with autoregressive models of cylindrical images and gives some expressions of the correlation function depending on the autoregression parameters are given. To represent heterogeneous images with random heterogeneities, ‘doubly stochastic’ models are used in which one or more images control the parameters of resulted image. The spiral scan of a cylindrical image can be considered as a quasiperiodic process due to the correlation of image rows. The article proposes the pseudogradient algorithms for the modal identification. The statistical modeling proves these algorithms give good model identification.

The analysed studies of combat simulation shows that the theory of dynamic systems, in particular the Lanchester model, is used for dynamic simulation of military conflicts. A large number of Lanchester models, each of which takes into account particular and specific factors, has already existed. However, these models examine a symmetric bilateral conflict. At the same time, in the Lanchester models class there are no models of multilateral conflicts. The purpose of the paper is to form the generalized Lanchester model of a multilateral conflict. The elements of scientific novelty of this model are to take into account different strategies of parties in a multilateral conflict and different conflict levels for the strategies. This model allows us to study the dynamics of resources changes of the conflict parties, to identify local wins and losses in the transition mode of the model, to draw conclusions about the global wins and losses of the parties, to form recommendations about choice of the parties’ strategies and the values of the parameters of their strategies for achieving a global win. The article outlines the ways for further research on the development of this generalized Lanchester model.

The article discusses an approach to calculating the performance of objects exposed to adverse effects (AE), based on Markov models of queuing theory operating in a random environment. Three types of models of service queuing systems with an unlimited and a limited queue are investigated differing from each other in the message processing modes performed in the recovery process after AE: (1) incoming messages continue to be executed with a different performance compared to the normal mode; (2) in the process of recovery, incoming messages are accumulated, and processing is blocked; (3) in the process of restoration, no messages are received and no processing of messages already in the queue is carried out. The modes of operation of objects change as a result of random influences of the external environment (cyberattacks, influences of the external environment or object failures). The models are considered under the simplest assumptions about the distributions of the input flows of messages arriving at the object, their service time, the distributions of the time of occurrence of the AE and the recovery time of the object after that (Poisson flows and exponential time of the considered time intervals). The developed models make it possible to evaluate the design decisions taken from the performance point of view on the organization of message service for a given survivability under stationary assumptions. Numerical examples illustrate the use of models for assessing performance indicators and some indicators of survivability of the objects under study.

The article deals with an adaptive method developed and an algorithm that implements it for the rapid evaluation of traffic characteristics and parameters in high-speed corporate multiservice communication networks. This algorithm operates in real-time environment. High-speed corporate multiservice networks are characterized by high dynamics of changing their state, including changes in the characteristics of transmitted traffic. Under these conditions, the automated network management system should provide the required quality of communication services and services provided to users. Thus, the relevance of this study is determined by the need to implement network management processes in a mode close to real time, with a given quality in the conditions of dynamic priority of unknown changes in network characteristics. The basis of the proposed method is the concept of conditional non-linear Pareto - optimal filtering by V.S. Pugachev, which consists in the fact that traffic parameters are estimated in two stages. Firstly, the forecast of parameter values is estimated, and then their correction is made with the following observations of parameters. Traffic parameter forecasts are made in a small sliding window, and refinement of current traffic parameter estimates is implemented by pseudogradient procedures, the parameters of which are regulated by the method of fuzzy Takagi-Sugeno logical output. In this case, increments in pseudo-gradient procedures are calculated relative to the average value of previous estimates calculated in a small moving window as well. This method reduced the average relative error of estimating the intensity parameters of non-stationary network traffic by 1.4-1.9 times, and also reduced the size of the sliding window in which it is processed from 1.7 to 4.2 times.The proposed method and algorithm belong to the class of methods and algorithms which require a preliminary training. The average relative error in estimating traffic parameters does not exceed 7%, which is a sufficient value for the implementation of operational network management tasks.

Stricter requirements for the efficiency and reliability of technical systems predetermine an in-depth study of electromechanical systems. The study involves taking into account the heterogeneity of their physical and vector space as operational factors that have a significant impact on the energy efficiency and reliability of the object. The proposed topological approach to the study of heterogeneous electromechanical systems (NEMS) is based on the analysis of their vector space. The multidimensionality, heterogeneity, and composite nature of the vector space are analyzed. Typical examples of the restrictions imposed on space vectors by the connection schemes of three-phase and multiphase NEMS windings are given. The main energy field is presented and the principle of the formation of the effective energy state of NEMS is formulated. Describes the tasks and method of implementing the operational diagnostics of NEMS based on the topological approach. In conditions of uncertainty, as well as heterogeneous quality, insufficient data, the feasibility of sharing the methods of fuzzy cognitive and logical analysis and modeling is substantiated. A cascade hybrid model is proposed, as well as methods for studying the vector space and operational diagnostics of NEMS based on it.

The article discusses the on-board information system that will ensure a safe and steady operation of a wheel-mounted boom lifting equipment. The proposed configuration of information panel clearly demonstrates all changes in the angle of boom-lift body orientation while performing necessary production operations and can prevent pre-emergency situations in time. The processing of logged performance values is a very complex and labor-intensive process. Therefore, authors propose to consider the possibility of using the software to reduce time required for performance analysis. The article deals with an algorithm presented here in the form of a block diagram for serial data acquisition, which allows processing logic chain data transferred from the measurement components. The presented mathematical expressions allow authors to calculate the time intervals required for data acquisition and the duration of experimental data recording for further analysis. The proposed combination of the measurement components of on-board information system includes tilt angle meters, force meters, an information panel, and a voltage maintenance unit. All that measurement components of the on-board information system are space saver and can be easily placed on the body of the boom lifting equipment. The figures and tables presented in the article indicate efforts at the creation and commissioning of the on-board information system for boom lifting equipment. As a result, it should be noted that the proposed on-board information system ensures the reliability of a wheel-mounted boom lifting equipment and it is also reasonable to use it for almost all wheel-mounted boom lifting mashines as well as for hoisting equipment.

Published: November 2021

Based on the analysis of the existing distributed control system of the diesel fuel mixing unit, the imperfection of the control loops of the kerosene fraction, the depressant-dispersant, cetane-increasing and antiwear additives were revealed due to the fact that they do not take into account the quality indicators of commercial diesel fuel if there are in-line analyzers of its characteristics in the automated system. It leads to the need for the operator to participate in the control of the flow rate of these flows. In this regard, the unit was simulated on the basis of experimental and statistical methods, based on the results of which a virtual analyzer of the lubricity of commercial diesel fuel was developed. Proposals have been formulated for the modernization of control loops with the consumption of depressant-dispersant and cetane-increasing additives, kerosene fraction, adjusted for the qualitative characteristics of commercial diesel fuel, as well as the consumption of antiwear additives, corrected according to the results of the readings of the developed virtual analyzer of the lubricity of fuel. Programs for the implementation of modernized control loops in the language of functional blocks of the Centum VP controller have been developed.

The article deals with the mathematical models of decision-making in the management organization systems. The models are based on the receptor-ligand interaction methods studied in the biokinetics. The article describes an interaction between initial data coming to the organization system and knowledge database generated on the basis of operation experience. The combination of matching pairs creates decisions for resolving problems and achieving the goals. The interaction may take one or more stages. For one stage the models were developed in the form of differential equations when the starting amount of data is not equal to the one in knowledge database. When the amounts are equal, the model is represented as Riccati equation in a special form solving by an indefinite coefficient. The article considers cases when information recourses of initial data and the ones of knowledge database are not uniquely defined. The similar models are developed for two stages of interaction. The article gives the examples of calculation of information recourses amount for a decision in case of different ratios of initial data/ knowledge database.

When monitoring a real production process using statistical methods, the question of early detection of violations arises. In most cases, several indicators are monitored simultaneously in the production process, and a change in the values of some indicators leads to a change in others. If there is a dependence of indicators for their monitoring, multivariate statistical control tools are used, in particular generalized variance chart. By varying the parameters of the chart, its efficiency can be significantly increased, this allows minimizing the time the process is in an unstable state.Applying the approach of A. Duncan, which he developed for Shewhart charts, a formula for the expectation of the duration of an unstable state of a process was obtained and a Python program was developed to minimize it. To test the set optimization problem, the calculation of the data of two process indicators is given and the optimal parameters of the generalized variance chart are obtained, at which the duration of the process in an unstable state is minimal.

Published: November 2021

The article deals with the solution to the problem of determining the motion mode of an object along a complex trajectory. A hybrid stochastic model is used to describe a complex trajectory. The solution of the problem is based on the application of a sequential decision rule about the choice at an unknown time of the hypothesis about the current mode of motion, with a limited size of the bank of competing Kalman filters. An algorithm is constructed for calculating the average size of the Kalman filter bank in the case of M-possible motion modes. The algorithm is developed in a general form, therefore, it can be used not only for the four types of object motion models considered in this paper, but also for any linear discrete-time models with Gaussian noise presented by equations in the state space. The algorithm for a priori estimation of the average size of a bank of competing Kalman filters for M-possible modes of motion is implemented in MATLAB, the results of computer simulation are presented.

The generalized variance algorithm is used to control the multidimensional scattering of the process. The generalized variance is understood as the determinant of the covariance matrix of the process. The control efficiency is estimated by the average length of the series, that is the number of observations from the moment of violation of the process to the moment of detection of this violation. Both analytical and numerical methods can be used to estimate the average length of the series for different control types. One of the most common types of the process violation is an abrupt or gradual increase in its dispersion. The aim of the article is to estimate the average length of the series of the generalized dispersion map under the trend of multidimensional scattering.

It is relevant for a developer of hardware and software systems to assess the duration of development in advance and determine the main factors influencing on its success. Bulk production or bulk production with little changes can be assessed based on the experience. However, when making preliminary assessment, some factors that had not a great effect before may not be considered. The article describes an approach to calculate the duration of hardware and software system development based on analogues, statistics and factors effecting the production. At the same time, it should be noted this method provides only a preliminary assessment and its usage requires additional s.

Two problems arise when extracting terms consisting of several words using linguistic methods of text analysis: 1. A linguist has no skills in software systems development, however he (she) is required to present his (her) knowledge in the form of software system fragments or constructions in a formal language. 2. Most software developers are not qualified enough in linguistics. This problem creates a semantic gap between the methods of linguistic analysis of texts and their software implementation. The article presents an approach to extract the terms consisting of several words based on syntactic patterns tailored for a linguist. The proposed approach does not require additional skills and usage of various languages to describe syntactic patterns by a linguist. The prototype of the software system was developed. The software system allows describing syntactic patterns without having knowledge of a formal language. Moreover, as against the analogs the developed system is capable to use syntactic patterns in external systems for text analysis. The server of the prototype has an interface to make the syntactic patterns.

The article gives a brief overview of standard methods of quality control and defect diagnostics of plated-through holes (PTH) of printed circuit boards (PCB) and considers their main disadvantages. It scrutinizes the methods of thermal control, which are reduced to PTH heating and monitoring the temperature. The main disadvantage of common methods is that they require a contact during heating the PTH and temperature measurement, which leads to significant errors and low reliability of control. The article describes a non-contact method involving heating only one side of the PTH by a laser beam and non-contact temperature measurement of the PTH ends by an IR camera. The authors propose a thermal equivalent scheme of PTH to analyze the transient thermal processes in PTH, which takes into account the heat removal from the plating of PTH into the PCB material. It is shown that the quality of plating can be estimated by the temperature difference between the upper (heated) and lower ends of the PTH, and the quality of adhesion between PTH plating and the PCB material can be estimated by the ratio of temperature increments. The article describes peculiarities of this method and gives the results of its testing on a real sample.

Introduction. The development of bilateral relations in the context of globalization and European integration involves expanding the range of forms of cooperation, as well as those areas covered by cooperation. The implementation of medical reform in Ukraine necessitates the intensification of the exchange of experience in the medical field with other countries, including Poland. The rapid processes of digitalization against the background of the Kovid-19 pandemic determine the modernization of communication tools and cooperation in the field of health services.The purpose of the article is to study the state and prospects of exchange of experience in the field of medical services between Ukraine and Poland.Research methods. To achieve the goal set in the article, general scientific and special methods were used, namely: analysis and synthesis, induction and deduction, abstraction and concretization, systematization, as well as elements of comparative analysis. The methodological basis for the study are national and international regulations of Ukraine and Poland, which regulate the functioning of health care and bilateral relations in the field of medical services, scientific works of domestic and foreign researchers, statistical reports and more.Results. The exchange of experience in the provision of medical services between Ukraine and Poland is carried out in a slightly different state of health care and taking into account Ukraine’s integration intentions using tools such as conferences, seminars, webinars, academic mobility of scientists and students, bilateral agreements between medical institutions with the support of local governments and self-government, etc. Digitalization, on the one hand, expands opportunities for collaboration, and on the other - necessitates the need to improve the quality of technical equipment of hospitals and makes new demands on human capital. Improving the exchange of experience in the field of  medical services is enhanced by receiving technical assistance from Polish partners, including under the auspices of international institutions, such as the EU, WHO, UNICEF, etc. Perspective areas are the introduction of the eHealth system in Ukraine, as well as the involvement of Polish specialists to modernize the management system in domestic health care facilities. The article details the recommendations for intensifying the exchange of experience between Ukraine and Poland in areas and tools.Perspectives. Future research is important to focus on an interdisciplinary analysis of the consequences of health care reform in Ukraine and Poland in the context of the impact on the well-being of citizens.
