If the solid body makes a spatial motion, then at any point in time this motion can be decomposed into rotational at angular velocity and translational at linear velocity. The direction of the axis of rotation and the magnitude of the angular velocity, that is the vector of rotational motion at a given time does not change regardless of the point of the solid body (pole), relative to which the decomposition of velocities. For linear velocity translational motion is the opposite: the magnitude and direction of the vector depend on the choice of the pole. In a solid body, you can find a point, that is, a pole with respect to which both vectors of rotational and translational motions have the same direction. The common line given by these two vectors is called the instantaneous axis of rotation and sliding, or the kinematic screw. It is characterized by the direction and parameter - the ratio of linear and angular velocity. If the linear velocity is zero and the angular velocity is not, then at this point in time the body performs only rotational motion. If it is the other way around, then the body moves in translational manner without rotating motion. The accompanying trihedral moves along the directing curve, it makes a spatial motion, that is, at any given time it is possible to find the position of the axis of the kinematic screw. Its location in the trihedral, as in a solid body, is well defined and depends entirely on the differential characteristics of the curve at the point of location of the trihedral – its curvature and torsion. Since, in the general case, the curvature and torsion change as the trihedral moves along the curve, then the position of the axis of the kinematic screw will also change. Multitude of these positions form a linear surface - an axoid. At the same time distinguish the fixed axoid relative to the fixed coordinate system, and the moving - which is formed in the system of the trihedral and moves with it. The shape of the moving and fixed axoids depends on the curve. The curve itself can be reproduced by rolling a moving axoid over a fixed one, while sliding along a common touch line at a linear velocity, which is also determined by the curvature and torsion of the curve at a particular point. For flat curves, there is no sliding, that is, the movable axoid is rolling over a stationary one without sliding. There is a set of curves for which the angular velocity of the rotation of the trihedral is constant. These include the helical line too. The article deals with axoids of cylindrical lines and some of them are constructed.

Authors:   National University of Life and Environmental Sciences of Ukraine, Aftandiliants Ye. G.
Published: May 2021

It is based of process analysis of structural steel operation at elevated temperatures and stresses, it is established that their workability depends with the chemical composition of steels and operation stress, time, temperature. The heat-resistant structural steels alloying is aimed for reducing the intensity of softening processes, that is, the redistribution of the alloying elements between the solid solution and the separation phases, their coagulation and changes of the crystal structure defects. The results of the study of chemical composition effect, temperature, stress and operation time on the creep and durability of structural steels are presented in the article. Analytical dependences of the relative elongation in the creep process and time at which the destruction of the chemical composition of heat-resistant structural steels and such operational factors as temperature, stress and holding are calculated. It is established that the creep and durability of heat-resistant structural steels, in the experiment conditions, are determined by their chemical composition in quantity 61–64 %, temperature 7–18 %, holding time 11 %, stress state 18–21 %. Nitrogen and vanadium alloying have been shown to more effectively reduce the softening degree heat-resistant steel during creep process than the molybdenum alloy, since the coagulation process of carbides and nitrides in steels with nitrogen and vanadium receives less development than carbides in steels alloyed by molybdenum.

The article analyzes the quality of the implementation of the optimal laws of simultaneous motion of the tower crane slewing and the trolley movement mechanisms. The estimation was carried out according to the maximum and root-mean-square values of the deviations of the theoretical and experimental characteristics. In addition, the graphical dependencies have been built. The data were estimated according to the characteristics of the speed of movement of the trolley and the rotation of the crane, as well as the angles of deflection of the load in the normal and tangential directions in the modes of acceleration and deceleration of the mechanisms. As a result of the analysis, it was found that the main reasons for the deviation of theoretical and experimental data on the characteristics under study are that the stiffness characteristics of the crane metal structure have not been taken into account, the parameters of the mechanisms are not accurately determined, and there are no feedbacks on the control characteristics (the speed of rotation of the crane and the speed of trolley movement). However, when implementing optimal control by means of a frequencycontrolled drive, pendulum oscillations of the load in the normal and tangential planes are eliminated. In addition, the analysis of the current loads of the drives of mechanisms and the acceleration of the crane boom was carried out. It was found that with optimal control, there is a significant decrease in the maximum values of acceleration, which means a decrease in dynamic loads on the crane metal structure. Also, the maximum currents in the motor windings of the crane mechanisms have been reduced, which, of course, will have a positive effect on the energy efficiency of the crane mechanisms.

Thus, it is suggested parents should focus on the growth and fitness of schoolboys by giving proper exercise time and a balanced diet.
THE INCREASE OF RIVER FLUOR CONTENT USING WHITE AND GREEN FLUORIDE STONE
Authors: Sari Emilda
Published: May 2021

Fluoride content in water consumed by the people of Mekar Sari Village, Tatah Makmur District, Banjar Regency, South Kalimantan Province is still below the WHO recommendation and the Ministry of Health of Indonesia. This study aims to determine the differences in the ability of fluoride stones from the peat area - Liang Anggang, Banjar Regency and fluoride stones from Tanah Laut area of South Kalimantan in increasing fluoride content in river water. This type of work is analytical research. The experiments were carried out in river water by means of preliminary treatment until the turbidity is less than 5 NTU. Furthermore, the processed water was re-circulated into a â€œflour increase portableâ€ device to manipulate the processed water with stones containing fluoride. Variations in research include 24 hours, 48 hours and 72 hours recirculation; fluoride stones types were from Liang Anggang area and from Tanah Laut. The results show that green stones from Tanah Laut area can increase fluoride content in processed river water to 0.63 mg / l. This means that the ability of this green stone is lower than that of white stone in increasing fluoride content in processed river water.
Choosing Interim Sample Sizes in Group Sequential Designs
Authors: Tarima Sergey , Flournoy Nancy
Published: May 2021

This manuscript investigates sample sizes for interim analyses in group sequential designs. Traditional group sequential designs (GSD) rely on “information fraction” arguments to define the interim sample sizes. Then, interim maximum likelihood estimators (MLEs) are used to decide whether to stop early or continue the data collection until the next interim analysis. The possibility of early stopping changes the distribution of interim and final MLEs: possible interim decisions on trial stopping excludes some sample space elements. At each interim analysis the distribution of an interim MLE is a mixture of truncated and untruncated distributions. The distributional form of an MLE becomes more and more complicated with each additional interim analysis. Test statistics that are asymptotically normal without a possibly of early stopping, become mixtures of truncated normal distributions under local alternatives. Stage-specific information ratios are equivalent to sample size ratios for independent and identically distributed data. This equivalence is used to justify interim sample sizes in GSDs. Because stage-specific information ratios derived from normally distributed data differ from those derived from non-normally distributed data, the former equivalence is invalid when there is a possibility of early stopping. Tarima and Flournoy [3] have proposed a new GSD where interim sample sizes are determined by a pre-defined sequence of ordered alternative hypotheses, and the calculation of information fractions is not needed. This innovation allows researchers to prescribe interim analyses based on desired power properties. This work compares interim power properties of a classical one-sided three stage Pocock design with a one-sided three stage design driven by three ordered alternatives.
Self-Harm Detection for Mental Health Chatbots
Authors: Deshpande Saahil , Warren Jim
Published: May 2021

Chatbots potentially address deficits in availability of the traditional health workforce and could help to stem concerning rates of youth mental health issues including high suicide rates. While chatbots have shown some positive results in helping people cope with mental health issues, there are yet deep concerns regarding such chatbots in terms of their ability to identify emergency situations and act accordingly. Risk of suicide/self-harm is one such concern which we have addressed in this project. A chatbot decides its response based on the text input from the user and must correctly recognize the significance of a given input. We have designed a self-harm classifier which could use the user’s response to the chatbot and predict whether the response indicates intent for self-harm. With the difficulty to access confidential counselling data, we looked for alternate data sources and found Twitter and Reddit to provide data similar to what we would expect to get from a chatbot user. We trained a sentiment analysis classifier on Twitter data and a self-harm classifier on the Reddit data. We combined the results of the two models to improve the model performance. We got the best results from a LSTM-RNN classifier using BERT encoding. The best model accuracy achieved was 92.13%. We tested the model on new data from Reddit and got an impressive result with an accuracy of 97%. Such a model is promising for future embedding in mental health chatbots to improve their safety through accurate detection of self-harm talk by users.
Use of Semantic Interoperability to Improve the Urgent Continuity of Care in Danish ERs
Authors: Andersen Sine Nordstrøm Lambert , Brandsborg Cecilie Mørk , Pape-Haugaard Louise
Published: May 2021

Reuse of patient data from prehospital electronic health record (EHR) to EHRs in emergency rooms is currently non-existing. In Danish EHRs, access to patient data recorded in prehospital settings is either not available or accessible in a PDF file. The amount of patient and administrative data registered at the prehospital unit is high and includes a rich representation of the accident, the patient and treatment. By applying emphasis framing to the representation of data, information overload can be diminished. Several international studies have investigated the suboptimal reuse of data within this field. Hence, the aim of this pre-study was to develop webservices based on emphasis framing to increase interoperability between the prehospital health record and the emergency room’s EHR. In this study, requirements engineering and emphasis framing was applied. Iterative linear requirement specification process was chosen as a frame to address the aim. The five included phases were revisited due to the iterative nature of this study. Tools used in the requirement engineering process were semi structured interviews and direct observations. The pre-study resulted in 12 Fast Healthcare Interoperability Resources (FHIR) profiles using SNOMED CT terminology bindings. The profiles contained elements which represented primarily patient data recorded in the prehospital setting. The profiles were compared to a case representing the urgent continuity of care to validate their ability to standardize data from prehospital health records. Conclusively, FHIR profiles can be modelled to standardize prehospital urgent patient data to support the patient trajectory. With the applied emphasis framing, the clinical context and content have been maintained.

Authors: Bowles Juliana , Webber Thais , Blackledge Euan , Vermeulen Andreas
Published: May 2021

To facilitate personalised healthcare provision across Europe, we envision solutions that enable the secure integration and sharing of medical health records. These solutions should address privacy concerns, such as granular access control to personal data, establishing what should be accessible when and by whom, whilst complying with collective regulatory frameworks such as the European General Data Protection Regulation (GDPR) and adhering to international standards on how to manage information security. The proposed healthcare system design integrates technologies such as blockchain and scalable data lakes with adequate system routines to guarantee the secure access of confidential data. In this paper, we present the essential architectural components for the secure integration of medical records in a blockchain-based platform. We present a patient-centric data retrieval approach which incorporates a structured format to compose access rules.

Published: May 2021

Blood products and their derivatives are perishable commodities that require an efficient inventory management to ensure both a low wastage rate and a high product availability rate. To optimize blood product inventory, blood transfusion services need to reduce wastage by avoiding outdates and improve availability of different blood products. We used advance visualization techniques to design and develop a highly interactive real-time web-based dashboard to monitor the blood product inventory and the on-going blood unit transactions in near-real-time based on analysis of transactional data. Blood transfusion staff use the dashboard to locate units with specific characteristics, investigate the lifecycle of the units, and efficiently transfer units between facilities to minimize outdates.

Published: May 2021

Skin cancer has become the most common cancer type. Research has applied image processing and analysis tools to support and improve the diagnose process. Conventional procedures usually centralise data from various data sources to a single location and execute the analysis tasks on central servers. However, centralisation of medical data does not often comply with local data protection regulations due to its sensitive nature and the loss of sovereignty if data providers allow unlimited access to the data. The Personal Health Train (PHT) is a Distributed Analytics (DA) infrastructure bringing the algorithms to the data instead of vice versa. By following this paradigm shift, it proposes a solution for persistent privacy- related challenges. In this work, we present a feasibility study, which demonstrates the capability of the PHT to perform statistical analyses and Machine Learning on skin lesion data distributed among three Germany-wide data providers.

An Electronic Health Record Approach to Understanding Drug to Drug Interactions and Associated Knowledge Gaps in Intergrated Care of Multimorbidity
Authors: Despotou George , Arvanitis Theodoros N.
Published: May 2021

Multimorbid patients are prescribed a number of medications in parallel, which may often interact with each other, resulting in adverse effects. However, clinical guidelines on prescription of medications predominantly focus on individual conditions do not consider the guidance in the context of other guidelines, resulting in conflicts. C3-Cloud is an integrated care architecture managing multimorbidity, which amongst others, provides clinical decision support, based on reconciled guidelines, and active monitoring of drug interactions. To identify the severe interactions that resulted from multimorbidity management, in order to reevaluate guidelines as well as to identify knowledge gaps in prescribing practice. Method: Descriptive statistical analysis of interactions identified by the C3-Cloud clinical decision support, collected from the C3-Cloud FHIR repository. As part of a feasibility study, a number of interactions were identified, along with variable practice in how chemicals are represented in the EHR. 191 known severe interactions were identified. The Atorvastatin/Verapamil interaction was the most frequent. The approach has identified a number of interactions where the severity was not available, highlighting the need for further clinical review.

Authors: Schmidt Thomas , Nøhr Christian , Koppel Ross
Published: May 2021

Information Security Awareness among employees in healthcare has become an essential part in safeguarding health information systems against cyber-attacks and data breaches. We present three simple security awareness questions that can be included in larger surveys gauging other aspects of information systems. The questions have been tested in a national Danish survey to evaluate correlations among medical profession, computer proficiency, experience, and place of employment. We find that dissatisfaction with system usability is strongly linked with reduced information security awareness, and that clinical professions have different responses to security concerns.

Published: May 2021

In Clinical Decision Support System (CDSS), relevance of alerts is essential to limit alert fatigue and risk of overriding relevant alerts by health professionals. Detection of acute kidney injury (AKI) situations is of great importance in clinical practice and could improve quality of care. Nevertheless, to our knowledge, no explicit rule has been created to detect AKI situations in CDSS. The objective of the study was to implement an AKI detection rule based on KDIGO criteria in a CDSS and to optimize this rule to increase its relevance in clinical pharmacy use. Two explicit rules were implemented in a CDSS (basic AKI rule and improved AKI rule), based on KDIGO criteria. Only the improved rule was optimized by a group of experts during the two-month study period. The CDSS provided 1,125 alerts on AKI situations (i.e. 643 were triggered for the basic AKI rule and 482 for the improved AKI rule). As the study proceeds, the pharmaceutically and medically relevance of alerts from the improved AKI rule increased. A ten-fold increase was shown for the improved AKI rule compared to the basic AKI rule. The study highlights the usefulness of a multidisciplinary review to enhance explicit rules integrated in CDSS. The improved AKI is able to detect AKI situations and can improve workflow of health professionals.
Social Determinant Trends of COVID-19: An Analysis Using Knowledge Graphs from Published Evidence and Online Trends
Authors: Gleize Martin , Mulligan Natasha , Di Bari Alessandro , Bettencourt-Silva Joao H.
Published: May 2021

This paper presents the results of a new approach to discover related health and social factors during the COVID-19 pandemic. The approach leverages a knowledge graph of related concepts mined from a corpus of published evidence (PubMed) prior to the pandemic. Population trends from online searches were used to identify social determinants of health (SDoH) concepts that trended high at the outset of the pandemic from a list of SDoH topics from the World Health Organization (WHO). The trending concepts were then mapped to the knowledge graph and a subsequent analysis of the derived insights, spanning two years, was conducted. This paper suggests an approach to derive new related health and social factors that may have either played a role in, or been affected by, the onset of the global COVID-19 pandemic. In particular, our results show how, from a list of SDoH topics, Food Security, Unemployment trended the highest at the start of the pandemic. Further work is needed to continue to ascertain the validity of the derived relations in a population health context and to improve mining insights from published evidence.

The exhaustive automatic detection of symptoms in social media posts is made difficult by the presence of colloquial expressions, misspellings and inflected forms of words. The detection of self-reported symptoms is of major importance for emergent diseases like the Covid-19. In this study, we aimed to (1) develop an algorithm based on fuzzy matching to detect symptoms in tweets, (2) establish a comprehensive list of Covid-19-related symptoms and (3) evaluate the fuzzy matching for Covid-19-related symptom detection in French tweets. The Covid-19-related symptom list was built based on the aggregation of different data sources. French Covid-19-related tweets were automatically extracted using a dedicated data broker during the first wave of the pandemic in France. The fuzzy matching parameters were finetuned using all symptoms from MedDRA and then evaluated on a subset of 5000 Covid-19-related tweets in French for the detection of symptoms from our Covid-19-related list. The fuzzy matching improved the detection by the addition of 42% more correct matches with an 81% precision.

Published: May 2021

To facilitate interaction with mobile health applications, chatbots are increasingly used. They realize the interaction as a dialog where users can ask questions and get answers from the chatbot. A big challenge is to create a comprehensive knowledge base comprising patterns and rules for representing possible user queries the chatbot has to understand and interpret. In this work, we assess how crowdsourcing can be used for generating examples of possible user queries for a medication chatbot. Within one week, the crowdworker generated 2‘738 user questions. The examples provide a large variety of possible formulations and information needs. As a next step, these examples for user queries will be used to train our medication chatbot.

Epidemics of diabetes and its complications is a global threat to the health of human population. In 2040, the number of patients with diabetes is predicted to rise to 642 million. Diabetic retinopathy and nephropathy are the most dangerous complications. Chronic hyperglycemia is a major factor that determines the development and progression of microvascular complications of diabetes including retinopathy and nephropathy. Key biological pathogenic mechanisms of microvascular complications involve over-production of reactive oxygen species and activation of intracellular signaling pathways and their modulators. OCT angiography is a safe and informative early diagnostic tool to assess vascular retinal abnormalities and to monitor treatment efficacy. Proteinuria was long considered the gold standard to evaluate and monitor kidney functions. However, one-third of patients develop diabetic nephropathy in normal albuminuria. Degradation products of glomerular filtration barrier are thought to be perspective biomarkers of early diabetic nephropathy. End-stage renal disease requires kidney transplantation. In addition to the improvement of uremic syndrome, kidney transplantation favors the course of diabetic retinopathy. Keywords: diabetes, diabetic retinopathy, diabetic nephropathy, optical coherence tomography, OCT angiography, kidney transplantation.

Dry eye disease (DED) is common in the general population, and the number of patients is growing. Several risk factors including the COVID-19 pandemic and associated ubiquitous personal protective equipment (such as eye wear or face mask) wearing and distance learning and telework contribute to this process. This disease more and more affects the quality of life and labor productivity. However, the prevalence of DED in Russia is understudied while the studies vary in quantity and quality thus preventing the compilation of data and their extrapolation on the general population. This issue is further exacerbated by the lack of study coordination in a whole country and, as a result, the use of different methods and diagnostic criteria, samples of unequal age, comorbidities, region, and climatic geographical living conditions. This review paper attempts to summarize major trends and issues and to outline ways to study and solve them. Keywords: dry eye disease, DED, prevalence, epidemiology, tear, ocular surface.

An Unattainable Ideal: Youth and Patriotism in Russia
Authors: Lassila Jussi
Published: May 2021

The chapter discusses patriotism’s role and future prospects in Russia in relation to its principal target, Russia’s youth. Beneath the overall conformism with the Kremlin’s patriotic policies, youth’s relatively marginal engagement with any fixed patriotic identity is to be found among a variety of patriotic activists who prefer a distinct patriotic position to the state and the rest of society. In generational terms, Russia is witnessing a deepening gap between the policymakers of patriotism and the youth. On the one hand, the state repeatedly attempts to strengthen patriotism as an ideological tool in controlling societal and cultural processes, while, on the other hand, youth’s departing views from Soviet-like modes of patriotic education ignite demands to increase the role of patriotism further. Over the course of the next 10–15 years, it is very likely that an change in the balance between Soviet-era and post-Soviet cohorts of policymakers and conductors of patriotic policies will have a significant impact on the role and meaning of patriotism in Russian society.
