Digitalisation in the Health Sector: A South African Public Law Perspective
Authors: Cachalia Firoz , Klaaren Jonathan
Published: November 2022

The landscape of the health sector in South Africa as seen from a regulatory perspective is rapidly changing under the disruptive impact of digitalisation. Drawing on a paradigm of "strong rights" protection, particularly a robust privacy law fit for the digital age and sourced in the nation's Constitution, the operationalisation and application of health privacy regulation in post-apartheid society is briefly described. The note then enumerates and assesses a number of specific digital health technologies currently in use in interventions in South Africa. To do so, we adopt the international World Health Organisation (WHO) classification of digital health interventions. We also cover the recent South African response to the COVID-19 pandemic, noting the establishment in South Africa of the COVID-19 Tracing Database and subsequent technological interventions aimed at enhancing contact tracing and other responses to the pandemic. The establishment of the initial database was a development at the interface of the law enforcement and health sectors, which raised concerns regarding its risks to privacy, but it also raised hopes regarding its potential rewards in protecting public health.

Authors: Hood Stephanie
Published: November 2022

For when extremely high transformation efficiencies are needed (e.g., for transforming plasmid DNA libraries). Adapted from An improved yeast transformation method for the generation of very large human antibody libraries. Overview: Using strain BY4742, transformation efficiencies were optimal using 400 µl of concentrated cells and 1 µg of plasmid DNA, yielding ~3.5 million transformants per electroporation. It is possible that other strains may have different optima. The protocol is designed to allow for 2 electroporations per culture (yields ~1ml of concentrated cells) and can be scaled up for producing libraries.
The Spaces of Social Services as Social Infrastructure: Insights From a Policy-Innovation Project in Milan
Authors: Bricocoli Massimo , Marani Benedetta , Sabatinelli Stefania
Published: November 2022

The spatial organisation of social services has long been residual for both urban planning and social welfare policies in Italian cities. This often results in randomly chosen locations and poor design arrangements, which ignore the role that space might play in fostering social life and inclusion. The scarce relevance given to the topic both in research and implementation is connected to the historical evolution of social services in the country and the scant resources devoted to their provision. Basing itself on the debate on welfare spaces and social infrastructures and drawing on a collaborative-research experience within an experimental policy-innovation project developed in Milan, this article tackles the role of space in social services provision following three directions. Firstly, it analyses how, at the urban level, welfare innovations and the interplay between urban planning and welfare policies might contribute to reshaping the traditional physical structures of social services and their map to favour more inclusive patterns of access to local welfare. Secondly, it investigates the role of social services as social infrastructures in increasing accessibility, reducing stigmatisation, and interpreting in a more inclusive way the complex public-private partnerships that allow welfare implementation nowadays. Finally, it discusses how, in the face of contemporary trends in the activation of welfare spaces, traditional urban planning tools are challenged in monitoring their increasingly dynamic distribution in the city. This highlights the need to develop innovative urban planning strategies and tools to effectively support decision-making and design.
ORIGINAL TEXTBOOK “WATER BODIES OF UKRAINE AND RECREATIONAL ASSESSMENT OF WATER QUALITY” WAS PUBLISHED
Authors:   Taras Shevchenko National University of Kyiv, LYUBITSEVA O.O.
Published: November 2022

The content of the textbook “Water bodies of Ukraine and Recreational Water Quality Assessment” published by Taras Shevchenko Kyiv National University professors Valentyn Khilchevskyi and Vasyl Grebin in 2022 was analyzed. The textbook, which is the first of its kind in Ukraine, describes water bodies objects of Ukraine, which gives an idea of their recreational potential. The book examines WHO recommendations on recreational water quality and the creation of recreational water safety plans, the EU directive on bathing water quality management, and features of regulatory assessment of water quality for recreational purposes in Ukraine. Quantitative characteristics of natural and artificial surface water bodies on the territory of Ukraine are as follows: 63,119 rivers; about 20 thousand lakes; 1054 reservoirs; 50793 – ponds; 6 large channels. The importance of the use of water for recreational purposes in the 21st century is put on a par with the economic and drinking and industrial water supply, as well as for the purposes of agriculture and energy. The WHO recommendations on recreational water quality, which are discussed in the training manual, are aimed at protecting public health through the safe management of water quality for recreational purposes, in particular: establishing national health targets for recreational waters, which include: microbial content (from fecal pollution); cyanotoxins (from harmful algal blooms); if necessary – other microbial hazards, beach sand and chemicals; development and implementation of recreational water safety plans (RWPS) for priority bathing places; carrying out constant surveillance and informing about the risks of diseases associated with recreational water and timely provision of information about health risks to the public. The training manual emphasizes that along with the normative assessment of the state of beaches by controlling state bodies, a system of international voluntary environmental certification of beach management is developing in the world. The “Blue Flag” program belongs to them. In 2021, 4,831 beaches and marinas in 50 countries received the Blue Flag. Beaches that received the “Blue Flag” are included in the list of the World Tourism Organization as recommended for visiting. Ukraine joined the Blue Flag program in 2010. And in 2021, 19 Ukrainian beaches were awarded the Blue Flag certificate..
The Method of Determination of Properties of Air Springs with Two Pressure Stages and Counterpressure
Authors: Nakaznoy Oleg A. , Tsipilev Alexander A.
Published: November 2022

BACKGROUND: The issues of choosing reasonable properties for suspension system of wheeled vehicles, including vehicles for agricultural purposes, still remain relevant, especially for the vehicles, which load capacity is comparable to their curb mass. Significant difference between static loads, acting in suspension under the curb and total masses of a vehicle, is a consequence of high load capacity. Two or three times difference is possible (depending on axles load distribution), whereas 70% to 80% of mass of trailing load is on rear axles. Use of convenient suspension systems with metal springs is not able to ensure demanded nonlinearity of properties, where non-zero static wheel travel under the curb mass is kept with reasonable value of period of vertical eigenmodes for curb-massed and total-massed vehicle as well as with dynamic factor value. Air springs with two pressure stages are more advanced solution, as they allow choosing stiffness for small and large wheel travel by means of operation of different pressure stages, which volumes are conditioned by differents stiffnesses in area of static displacement.
AIMS: The aim of the study, which results are given in this paper, is to develop the method of determination of main design parameters and characteristics of air springs with two pressure stages (stiffnesses) and counterpressure, applicable for ensuring non-zero static wheel travel of curb-massed vehicles with keeping the given value of dynamic factor.
METHODS: The analytical analysis methods are used.
RESULTS: An example of implementation of the developed method for the KamAZ-53215 Selhoznik truck is given as the study result.
CONCLUSIONS: The dependencies, presented in the paper, make possible to determine main design parameters of uncontrolled air suspensions with two pressure stages (and stiffnesses) and counterpressure for wheeled vehicles, which give an opportunity to ensure given values of static wheel travel and dynamic factor and, in addition, provide insignificant increase of stiffness in comparison to air suspensions without counterpressure.

Authors: Altukhova Tatyana A. , Altukhov Sergey V. , Shukhanov Stanislav N.
Published: November 2022

BACKGROUND: The solving of priority tasks for the development of the agro-industrial complex considers the creation of advanced scientific developments. Innovative research of technical means and technologies of mechanization of agricultural production is not an exception in this regard. In the agricultural sector of Russia, crop production occupies a key place, in which the cultivation of grain crops is a priority. In the whole range of operations in the production of grain, the most important part of it is post-harvest processing of grain. One of the main stages in the post-harvest processing of grain is drying, in which the raw materials are brought to the moisture regain (down to 14%). Proper preparation of grain for storage ensures its reliable safety.
AIMS: Modernization of the granular materials dryer by means of new technical solution at the level of patentability.
METHODS: Research of the state of the issue on the topic under consideration with the help of a review of literary sources. Patent search for technical devices of grain dryers. Studying the principle of their functioning and design features. Analysis and generalization of the material for the adoption of a new design solution.
RESULTS: The use of innovative technologies with the new generation harvesters, characterized by high productivity, has significantly reduced the duration of harvesting, and this, in turn, has significantly aroused the interest in drying. The use of dryers with improved quality indicators of functioning significantly reduces the time for preparing raw materials for long-term storage, reduces grain losses in the field during harvesting, and, in addition, makes it possible to carry out the process of transferring grain from the field to a special long-term storage warehouse in the shortest possible time and with the least losses. There are various ways of drying granular materials. These are main methods based on increasing the temperature of the processed material. Drying of grain with the help of heated air has become the most widespread.
CONCLUSIONS: As a result of the conducted research, the drawbacks of existing technical devices for granular materials drying, as well as the principles of their functioning, have been revealed. A detailed analysis of literary sources, including a patent search, made it possible to upgrade the processed raw materials dryer, characterized by a simple and reliable design.
Justification of the design parameters of the blade of the rotary working body of the solid fertilizer spreader
Authors: Shvarts Anatoly A. , Korotkov Ilya V.
Published: November 2022

BACKGROUND: Organic, mineral and organomineral fertilizers in both granular and powder form are used in agricultural production in order to increase of soil fertility significantly, as well as to replenish soil reserves of micro-, meso- and macroelements. For fertilizer screening on a surface of a field, agricultural producers use machines with centrifugal-type working bodies which have horizontal or vertical rotation axis. In pursuance of the task of reducing the shift time consumption, a number of researchers find it reasonable to use a low-frame design of the machine to make direct loading of it from the dump truck body possible. For machines, having such design, rotary spreading working bodies with blades on a horizontal rotation axis are the most suitable.
AIMS: The article is concerned with the justification of the design parameters of the blades of the rotary spreading working body of the low-frame body spreader of solid mineral and organomineral fertilizers.
METHODS: The length of the working surface of the rotor blade with a horizontal rotation axis is justified theoretically for the most uniform distribution of solid fertilizers. An example of calculating the length of the blade of such a device based on the previously established overall dimensions of the spreader is given.
RESULTS: On the basis of experimental data, the expediency of using trough-shaped blades with a length of 110 mm was confirmed. The most effective design parameters of the dimensions of the rotor blades for screening fertilizers were established, taking into account the reduction of possible options for fertilizer granules crushing by means of preventing their recirculation inside the rotor casing. The relevance of research of devices with rotary working bodies on horizontal axes of rotation is argued.
CONCLUSIONS: Possible prospects for future research and the possibility of further improvement of the low-frame granular fertilizer spreader are proposed.

Variación espacio-temporal del valor b en el Volcán Cerro Machín, Colombia
Authors: Makario-Londoño John
Published: November 2022

Se llevó a cabo un estudio de la variación espacio-temporal del valor b de la relación frecuencia-magnitud de sismos ocurridos en el Volcán Cerro Machín (VCM), Colombia, para el período 2007-2020. Se pudo establecer que el valor b presenta variaciones espaciales caracterizadas por valores altos (1,1-1,3) en la parte superficial del volcán, debajo del domo principal y hasta una profundidad de 1 km. Entre 1 y 6 km de profundidad, se observaron valores normales a bajos (0,8-0,6). Bajo el domo Tapias, entre 8 y 13 km de profundidad, se observaron valores altos de b (1,1-1,3). Estos valores anómalos indicarían zonas de circulación de fluidos hidrotermales en la parte superficial y posibles reservorios de magma en la parte más profunda del VCM. Adicionalmente, se observaron variaciones temporales del valor b; se destacan tres cambios importantes, relacionados con variaciones en la actividad del VCM: el primero, ocurrido en noviembre 2008, se asoció con un enjambre al NE y E del domo principal (3-5 km de profundidad); el segundo, ocurrido en agosto-diciembre 2010, se asoció con la presencia de sismicidad profunda (12-18 km) a unos 8 km al SE del domo principal, y el tercero, ocurrido en febrero de 2018, se asoció con un enjambre sísmico (3-5 km de profundidad) al SW del domo principal. Estos tres cambios se interpretan como posibles intrusiones de pulsos de magma, asociadas a un dique o silo superficial (<4 km de profundidad) y a una entrada de magma a mayores profundidades (>15 km). Algunos de estos cambios en el valor b estuvieron asociados con cambios geoquímicos o de deformación de la superficie. Los resultados de este estudio muestran que el cálculo rutinario del valor-b sirve como herramienta de monitoreo volcánico para el VCM.

Authors: Kanwal Naumana , Iqbal Muhammad Javed , Mushtaq Mariam
Published: November 2022

Syntactic choices and complexity reduction make translation communicative for the readers. This paper underscores the syntactic choices as well as complexity reduction in Urdu translation of Punjab laws in English. The study focuses on legal communication in a minimalistic perspective. It draws upon the theory of minimalism proposed by Chomsky (1993), along with the three-stage model by Nida and Taber (1969). Data is analyzed by employing Burton’s (2021) clausal analysis. The legal data used for the research comprises Punjab laws in English and their Urdu translation. The findings reveal minimalism as a useful strategy in the translation process for reducing structure complexity and making the translation understandable to laypeople. The study is beneficial to English-Urdu translators since it instructs them on how to make their translations communicative, especially when dealing with legal texts. It is also useful for academics in the field of Translation Studies who are working on minimalist views.Keywords: minimalism, complexity reduction, legal translation, syntactic choices, communication

Authors: Gil-Plazas Andres-Fernando , Rubiano-Buitrago Julián-David , Boyacá-Mendivelso Luis-Alejandro , Herrera-Quintero Liz-Karen
Published: November 2022

4340 steel powders were processed with an additive manufacturing process using the FFF (Fused Filament Fabrication) technique. A composite filament was developed to print samples and study the effect of the bed and nozzle temperatures on its physical and microstructural properties. The printed samples were debinded and sintered by: Solid State (SS) at 1300 °C or SLPS (Supersolidus Liquid Phase Sintering) at 1420 °C. Metallography and scanning electron microscopy (SEM) identified the microstructure and phases. The hardness of the sintered samples was measured with the Vickers method. The SLPS process contributes to better densification and volume contraction; however, it promotes geometrical distortion of the samples compared to the SS samples. The microstructure of the sintered samples consists of ferrite situated in the original austenite grain and bainite. The sintering mechanism significantly influenced the hardness of the samples. Finally, a part was designed, printed, debinded, and sintered with the aim of studying the maximum inclination angle, the minimum vertical and horizontal holes, and the minimum vertical layer thickness, which can be obtained through the whole process.

The services supported by data networks have become widespread, so the architectures of the new data networks are service-oriented. They are endowed with intelligence, flexibility, and programmability. The preceding is with the aim of providing acceptability by users. Thus, this paper presents the construction of a video transmission scenario over a software-defined network (SDN, Software-Defined Networking) using free software and modifying its behavior with background traffic, on which the Quality of Experience (QoE) is estimated. Subjective and objective metrics were used for the QoE estimation. For the first one, the Mean Opinion Score (MOS) was used, while the second one was studied with the Full Reference Image Quality Assessment (FR-IQA). Finally, a correlation between the two types of metrics was proposed.
“The Devil in Disguise”: A Test of Machiavellianism Instruments (the Mach-IV, the Machiavellian Personality Scale, and the Five Factor Machiavellianism Inventory)
Authors: Grabovac Beata , Dinić Bojana M.
Published: November 2022

The main aim of this study was to test the the convergent, discriminant, and criterion validity of the Serbian adaptations of three Machiavellianism instruments (Mach-IV, Machiavellian Personality Scale - MPS, and Five Factor Machiavellianism Inventory - FFMI) based on their relations with HEXACO traits, distress aspects (anxiety, depression, and stress), and emotion regulation strategies (supression and reapraisal). The sample included 195 participants (80% women). The results showed that the Mach-IV and the MPS are mutually more similar to each other and their main negative correlate is Honesty-Humility, while the FFMI appears as distant from the other instruments and its main positive correlates are Extraversion and Conscientiousness and a negative one is Emotionality. Furthermore, the Mach-IV and MPS showed positive relations with distress aspects and non-adaptive emotion regulation (supression), while the FFMI showed opposite patterns of relations. Since the FFMI captures the most items and facets, it explained the most variance of distress and regulation strategies, but the Mach-IV and the MPS, especially its amorality facet, showed significant incremental contribution in explanation of anxiety, stress, and suppression. The implications of the use of each of the three instruments are discussed.

Brand registration is a crucial aspect of running a product for business advantage. It is very important that the parties will fight over the brand even though there are many other brands that can be used because the brand serves as the business image. In Indonesia, trademark registration and legal protection of counterfeit marks are regulated in Law Number 20 of 2016 on Marks and Geographical Indications. This is a normative legal research, which the study concludes that the laws and regulations that have been enacted are deemed sufficient to provide legal protection against trademark disputes that may arise. However, the problem lies in the subject matter, namely the operator who examines the application for registration of the mark and the applicant for the mark.

The mechanism for filling the post of interim Chief of Region in the pre-election 2024 leaves a problem with the future of democracy and constitutionalism. This study aims to answer the urgency of rearranging the mechanism for filling the positions of Chiefs of Region from the constitutional democracy. This research method uses normative/doctrinal research using a statutory and conceptual approach. The results of this study conclude: that there is an urgency to rearrange the filling of the position of the acting Chief of Region on the grounds that a) the central government has taken the constitutional rights of the people in the regions by appointing an official; b) There has been a shift in regional autonomy in the implementation of general elections, in this case the Minister of Home Affairs does not authoritatively consider the input of the governor in filling the temporary position of the acting Chief of Region. With such urgency, it should be the regional secretary who must fill the vacancy in the pre-election position in 2024.

Published: November 2022

The electrochemical CO2 reduction reaction can lead to high value-added molecules production while helping decrease anthropogenic CO2 emissions. Copper can reduce CO2 to more than thirty different hydrocarbons and oxygenates, but it lacks the required selectivity. We present a computational investigation of the role of nano-structuring and alloying in Cu-based catalysts on the activity and selectivity of CO2 reduction to one-carbon products: carbon monoxide, formic acid, formaldehyde, methanol, and methane. The adsorption, activation, and conversion of CO2 were computed on monometallic and bimetallic (decorated and core-shell) 55-atom Cu-based clusters. The dopant metals considered were Ag, Cd, Pd, Pt, and Zn, located at different coordination sites. The relative binding strength of the intermediates at different applied potentials were used to identify the optimal catalyst for the selective CO2 conversion to one carbon products. It was discovered that single atom doping with Cd and Zn is optimal for the CO2 to carbon monoxide conversion. The core-shell models with Ag, Pd, and Pt provided higher selectivity for formic acid and formaldehyde. The Cu-Pt and Cu-Pd showed lowest overpotential for methane formation.

Our search returned ten (10) eligible articles involving 1,713 viral cirrhosis cases representing eight (8) countries. A meta-analysis was performed on our eligible studies using the random effect model. A protocol was registered with PROSPERO (CRD42022321790). Results: The pooled prevalence of SBP in HBV associated cirrhosis had the highest estimate [8.0% (95% CI, 2.7 – 21.0%; I2= 96.13%; p < 0.001)], followed by SBP in HCV associated liver cirrhosis [4.0% (95% CI, 1.3% – 11.5%; I2 = 88.99%; p < 0.001)]. China (61.8%, CI: 57.1 – 66.3%), the USA (50.0%, CI: 34.6 – 65.4%), and Holland (31.1%, CI: 21.6 – 42.5%) had the highest estimate for SBP in HBV associated liver cirrhosis, SBP in HCV associated liver cirrhosis and SBP in HBV+HCV associated liver cirrhosis respectively. There was a significant difference in the prevalence of SBP in viral hepatitis-associated liver cirrhosis with the year of sampling and method of SBP detection at P<0.001. There was an increase in SBP incidence at the beginning of 2016 across the liver cirrhosis in this study. Conclusion: The findings of this review revealed an increase in the incidence of SBP in viral hepatitis over the last decade, the latter could be due to the global increase in Bacterial resistance. This indicates a possible future rise in the global prevalence of SBP among HBV, and HCV-related liver cirrhosis.

Authors: Alguacil Francisco José , López Félix Antonio
Published: November 2022

The behaviour of the pseudo-protic ionic liquids TOAH+Cl- and TODAH+Cl- in the facilitated transport of indium(III) from HCl solutions is described. Metal transport is investigated as a function of different variables: hydrodynamic conditions, HCl concentration in the feed phase and indium and carrier concentrations. The experimental data are used to model both transport systems and to estimate diffusional parameters associated to them.

Published: November 2022

The processing of semi-structured textual data for further use in DM models is a labor-intensive process, which, in addition to material costs, can increase the time required to build a model, and, as a result, worsen the efficiency of decision-making. This article presents visual models of semistructured text data and methods for their processing at the stage of exploratory analysis. Exploratory analysis will reduce the time to select significant variables at the initial stage of the study and, in the future, avoid the processing of redundant or insignificant variables. The use of visualization will help to include in DM model and process only data that will improve DM model quality. The process of using visualization of textual data in the process of exploratory analysis and the construction of two types of visual models is described - interactive "quantitative" visualization and visualization of relationships between words and other variables in the data under study. Approbation of the developed models is described on the example of labor market analysis. Examples of visualization of the content of the "soft skills" field from the CV and vacancies are presented, displaying both the skills most often mentioned by applicants from various professional fields, and the impact of mentioning these skills on inviting applicants for interviews. The experiment showed that the use of the developed visual models makes it possible to determine whether it is necessary to include a text variable in the DM model at the stage of exploratory analysis.

Published: November 2022

Unmanned aerial vehicles (UAVs) can be used to improve the efficiency of searching for missing people and vehicles in the natural environment. However, the use of UAVs alone may not be enough. To get a tangible effect, the authors of the article are developing a software package that includes a neural network core for processing images from UAVs, a web interface for the coordinator of the search operation and a mobile application for members of search groups working on the ground. The article substantiates the importance of the visualization subsystem for the software package being developed. The data output for the coordinator of the search operation and the participants of the search groups working on the ground are systematized. The following types of data are highlighted: information about the search area and the search targets; information about the image sets from flights and about image analysis; information about the participants of the search operation; information about the progress of the search operation; data about the search operation for a member of the search group; data on the results of search operations. Approaches to visualization of the listed data are described, interface elements for their visualization are selected and developed. Improvements to the software package are proposed and implemented considering the requirements for visualization.

Authors: Charninе Michael Mikhailovich
Published: November 2022

This paper presents the results of a method designed to realize visualization of long-term prediction of trending research topics in the field of social and cognitive robotics. Meaningful topics were identified among the words included in the titles of scientific articles. The longevity of the citation trend growth was the target for the machine learning algorithm CatBoost. We conducted experiments on a dataset including 5 million scientific publications to demonstrate the effectiveness of the proposed model. The accuracy rate of 5-year forecasts for a number of experiments was about 60%. Trending topics are built from trending keywords located closely in the semantic vector space. The following trending topics in the field of social and cognitive robotics have been identified: recognition, deep learning, engagement, disorder, conversation, cognitive computing, attention, robotic platform. Trending keywords and topics are visualized on a semantic map built using the t- SNE method. Visualization helps to see the Big Picture, identify promising directions, understand trending topics and reveals related keywords.
IR Sensor Test System

Published: November 2022

Methods for testing IR sensors, which are currently widely used as a source of information about the environment in various sectors of the national economy, are being investigated. It is shown that due to the transformation of the informative parameters of the observed scene by the sensor, information loss at the output of the device is possible. The structure of the testing system has been developed, the main element of which is a patented generator of reference test signals, which makes it possible to evaluate the following informative parameters: thermal signal characteristic, distortion, resolution. The heat-signal characteristic is built as a result of scanning heated plates, statistical processing of measurement results and approximation of the results of statistical processing by a linear dependence. Distortion is estimated based on the results of assessing the coordinates of the IR LEDs on the stage of the generator of reference test signals. The resolution is estimated by the results of constructing the surface of values of the output signal of the IR sensor when scanning heat-generating plates located at some angle to each other. For each case of assessing the information content, an appropriate assessment methodology is proposed. The results are recommended for use at enterprises involved in the development, production and operation of IR sensors.
