BackgroundCancer survival in the UK remains low compared to other Western countries including Australia, Canada and European countries. Delays in cancer diagnosis have an adverse impact on patient well-being and survival. Welsh Government outline a number of challenges with respect to earlier cancer diagnosis, including a lack of awareness of ‘red flag’ symptoms and difficulties among GPs and other healthcare professionals in identifying cancers that present with vague or non-specific symptoms. For some cancers, earlier diagnosis is associated with greater survival, better patient experience and quality of life, and lower healthcare costs.

MethodsThe ThinkCancer! intervention is a complex behaviour change intervention, which aims to change the behaviours of primary care practice teams when thinking of and acting on clinical symptoms that could be cancer. From an NHS perspective, we conducted a feasibility economic analysis of the ThinkCancer! intervention. We used micro-costing methodology to determine whether it was feasible to gather sufficient economic data to cost the ThinkCancer! intervention. Due to the Covid-19 pandemic, the intervention was mostly delivered remotely in a digital format. Intervention deliverers completed data collection sheets (including forms recording materials used and intervention deliverer time) and provided information on primary care staff attendance at each of the ThinkCancer! workshops. Budget impact analysis and sensitivity analysis were conducted to explore the costs of face-to-face delivery of the ThinkCancer! intervention as intended pre-COVID-19.

FindingsThe total costs of delivering the ThinkCancer! intervention across 19 general practices in Wales was £25,030. Costs per practice ranged from £431 to £2,498, with an average cost per practice of £1,311 (SD: 579.5). The potential budget impact if the intervention were to be delivered face-to-face across the 19 general practices would be £34,630. Sensitivity analysis revealed that if the intervention were to be delivered by one GP educator, the total estimated cost for face-to-face delivery would be £31,232. With the addition of one support role assisting the GP educator with the intervention delivery, the total cost of face-to-face delivery is estimated to be approximately £33,138.

ConclusionsResults of this feasibility study are being used to inform a definitive economic evaluation alongside a pragmatic randomised controlled trial. Primary care interventions to expedite the diagnosis of symptomatic cancer have the potential to reduce large costs to the NHS and improve patient and carer outcomes as later stage cancer treatments are often longer, more aggressive to patients, with larger associated healthcare costs compared to earlier stage treatment.

Published: March 2022

BackgroundAlmost twenty percent of women worldwide experience mental health disorders following childbirth. Despite their importance and consequences, postpartum psychiatric disorders are still under-investigated. In Brazil, studies are restricted to state capitals and are not representative of the country as a whole. Understanding the factors associated with postpartum psychiatric disorders can provide insights for adequate maternal mental health screening. This study was conducted with the objective of evaluating factors associated with postpartum psychiatric disorders in Brazil.

MethodsWe used Authorization of Outpatient Procedure data for women who used community mental health services in Brazil between 2008 and 2012. The dependent variable was the diagnosis of mental disorders and behavioural factors associated with the puerperium (ICD-10 code F53). Age categorized in quartiles and Psychosocial Care Centre (CAPS) coverage were covariates considered for the analysis. To partially neutralize the bias from repeated observations, we used the Proximity Index (PP), created through of geographic information for each visit to the level of the patient’s neighbourhood. We used Generalized Additive Models for Location, Scale, and Shape (GAMLSS) with double Poisson distribution.

FindingsWe identified 6,802 records of mental and behavioural disorders associated with the puerperium diagnoses. Among them, 47.6% of the outpatient records were for diagnosis of ICD F53.1, and 32.09% for ICD-10 F53.0, which correspond to severe and mild mental disorders associated with the puerperium, respectively. Diagnosis for ICD-10 F53.0 was higher between the ages of 26 and 30 (10%), while diagnosis for ICD F53.1 was higher between the ages of 31 and 35 (12.7%). For each increment in the maternal age unit and CAPS coverage percentage, there is an increase of 1.01 (p<0.001) in the occurrence of postpartum psychiatric disorders.

ConclusionsOur results showed that increases in maternal age and municipal CAPS coverage heightened the risk of postpartum psychiatric disorders. With regards to severity, we found that diagnosis for ICD F53.0 (mild mental and behavioural disorders associated with the puerperium) was higher among women aged between 26 and 30, while diagnosis for ICD F53.1(severe mental and behavioural disorders associated with the puerperium) was higher among women aged between 31 and 35. Our findings support the need to improve knowledge of maternal mental health and to integrate routine screening into postnatal care settings, for the early identification of women who are at risk, and to apply timely preventive and therapeutic approaches.

Sex Differences in Health Behaviors of Austrian Teachers and School Principals
Authors: Motevalli Mohamad , Tanous Derrick R. , Wirnitzer Katharina
Published: March 2022

IntroductionCurrently, about 2% of the European working population (~5 million people) are teachers, who are a characterized occupational group with various roles as educators, partners, counselors, social directors, professional managers, and political theorists. Teachers’ health has a remarkable effect on teaching quality, and consequently, on the success of students of future generations. Public and occupational health are highly related to lifestyle behaviors (including diet type and PA); however, little is known regarding lifestyle patterns in different groups of teachers, particularly males and females. This study aimed to investigate sex differences in health/lifestyle behaviors of Austrian secondary-level teachers and school principals.

MethodsThis cross-sectional and multidisciplinary study is a part of the bigger Austrian-wide research project From Science 2 School (www.science2.school/en; supported by Federal Ministry of Education, Science, and Research). A sample size of 89,243 teachers and principals from 2,554 secondary schools (level I & II) were invited to participate, and a total number of 1,350 teachers and principals (1.5% of eligible Austrian participants; aged 45.8±11.4; 69.7% females) completed an online survey. In addition to sociodemographic information, a complete profile of lifestyle behaviors (e.g., diet type: omnivorous, vegetarian, vegan; nutritional patterns; exercise and sports activities; smoking habits; and alcohol consumption) was evaluated.

FindingsMale teachers were 2.1 years older than females (p<0.01). While there was no sex difference in leisure-time sports participation (p>0.05), males engaged in club sports more than females (39.1% vs. 24.9%; p<0.01). The frequency of sports/exercise engagement was higher in males compared to females (3.1 ± 1.5 vs. 2.9 ± 1.4; p=0.02). Omnivorous diet was significantly more common in male teachers (93.9% vs. 87.2%; p<0.01), while a vegetarian diet was significantly more prevalent in females compared to male teachers (9.8% vs. 3.4%; p<0.01). There was no significant difference between male and female teachers in the prevalence of vegan diet (p>0.05).

ConclusionDespite some differences in lifestyle components between females and males, teachers in both sexes appeared to have a healthier lifestyle compared to general populations reported by similar investigations. This finding might be associated with the higher educational level of teachers, particularly their improved individual capabilities (including knowledge, skills, competencies, values, and qualifications) and social advantages (e.g., networks, general living conditions) to implement toward scientifically well-accepted healthy behaviors. This study can serve as a starting point for future health-related interventions focusing on sex differences in the dual approach of “healthy eating – active living” considered the practical recommendation to achieve sustainable health.

Molecular biology applications of the red king crab duplex-specific nuclease
Authors: Shagin DA , Rebrikov DV
Published: March 2022

Duplex-specific nuclease (DSN) from hepatopancreas of the craboid Paralithodes camtschaticus (red king crab) has a unique combination of properties. Along with thermal stability and a high optimal temperature of catalysis, this enzyme exhibits high substrate selectivity, cleaving only DNA in duplexes (DNA-DNA or DNA-RNA). Accordingly, it digests neither single strands (nor single-stranded regions) of DNA, nor RNA strands with any secondary structure. Such properties make it possible to create unique protocols based on DSN, which is also an important object of fundamental research in the field of nuclease evolution. The review considers diverse applications of the red king crab DSN in modern methods of molecular biology.

Following Government Policy, the face-to-face teaching system is now being transferred to the online system or known as the online system. The problems that arise in choosing the right method to use in the teaching and learning process in the midst of thispandemic are a dilemma for teachers. Some of the alternative applications offered must be adapted to the conditions of the school, teachers and students. The application used must be able to be accessed and understood by every teacher and student so that learning objectives can be achieved. The focus of this research is the use of Google Classroom media in online learning and its advantages and disadvantages. Researchers conducted field research with a descriptive qualitative approach to the learning process in schools. The results show that online learning through Google Classroom has advantages and disadvantages. The advantages include that teachers can use various media for the learning process, both those contained in the Google Classroom or other media that can be linked to the classroom. While the drawbacks are network problems and the limited quota that students have can be an obstacle in the learning process, as well as the low level of student activity in the learning process. Almost 31 students who answered the questionnaire stated that Google Classroom was not very effective because it certainly could not replace face-to-face meetings. Because there are many things that cannot be done through google classroom.

Climate Change (Policy) Skepticism: Policy Performance Risk and Support for Fossil Fuel Taxation among Europeans
Authors:   ", CAMPBELL Jesse W. ,   Associate professor, Department of Public Administration, Incheon National University, Incheon, South Korea"
Published: March 2022

"Concern about climate change does not translate unconditionally into support for policy action, and some citizens are skeptical that (costly) public policies will address climate change effectively. I argue that risks to policy performance at the country level attenuate the link between climate change concern and support for policy action. Using a large sample of public opinion data from residents in 23 (mostly) European countries and both country and respondent- level estimates of policy performance risk, I demonstrate that the link between climate change concern and support for fossil fuel taxation is weaker for citizens in countries where policy performance is threatened. This result holds regardless of whether risk is operationalized as governance or economic risk. I discuss the need to overcome climate change policy skepticism in contexts with stronger policy performance risk profiles."

THE SITUATION OF DIGITALIZATION OF INCLUSIVE EDUCATION AND THE PROBLEMS IN ARMENIA
Authors: Asatryan Samvel
Published: March 2022

There is no doubt to state that the 21st century is the century of digital information and endless technological possibilities. A century when thousands of new high-tech mechanisms are being created at an incredible speed, the main goal of which is the most comfortable and convenient life for people. Digital technologies have filled almost all spheres of human life and activity. Today, a large number of countries in the world have a successful experience in the introduction and use of digital technologies in education. Undoubtedly, they play a special and important role in the education of people with disabilities, the disabled and people with special needs.
The exercise by persons with disabilities of the right to education, a fundamental human right, is fraught with several challenges. The lack of necessary conditions for full participation in the educational process that meet the individual needs and abilities of students, as well as the use of insufficiently effective teaching methods, leads to the fact that the youngest people with disabilities cannot get a good education and profession. The inaccessibility of education is one of the main reasons preventing the full inclusion of disabled people in the life of modern society.
Results of the study indicate that the correct use of the capabilities of modern digital technologies by the teacher will contribute to effective work to overcome violations of psychophysical development.

Strengthening the strategic protection of Russia in conditions of external geopolitical challenges by means of settlement of the Russian space
Authors: ZAKHAROV Valerii K.
Published: March 2022

Subject. The paper is devoted to the description of population and life support settlement of the Russian space as an internal strategic response to the external geopolitical challenge of the Pan-American geopolitical world.
Objectives. The aim is to describe strategic and tactical aims of the Pan-American geopolitical world in the worldwide Pan-American hegemonic exploitation project, special aims of this project with respect to Russia, and to point out the way of necessary and possible Russian counteraction to the achievement of these aims.
Methods. The study employs the population and space conception of strengthening the strategic protection of the State by means of population and life support settlement of the Russian space.
Results. The paper describes the Pan-American hegemonic exploitation project, aimed at strategic retaining of the achieved USA-centered world order. Within this project, the Pan-American geopolitical world is forced to realize the strategic restraint of the European Union and China as its major geopolitical and geo-economic rivals. This strategic restraint is impossible without establishing a complete control over Russian natural resources and infrastructure by the Pan-American world.
Conclusions. In conditions of the said external geopolitical challenge, Russia will not be able to ensure its strategic protection without its own population and life support settlement of the Russian space. The paper provides a theoretical substantiation of necessary economic and administrative measures directed to the said strategic settlement.
Forecasting cryptocurrency market prices
Authors: IVANCHENKO Igor' S.
Published: March 2022

Subject. This article explores the cryptocurrency market and the changes in the three most popular cryptocurrencies currently, namely Bitcoin, Ethereum and Tether, in particular. Objectives. The article aims to answer the question whether it is possible to predict the cryptocurrency rate taking into account the high market value volatility or not. Results. Testing the cryptocurrency market for information efficiency made it possible to choose the most adequate model for predicting the market prices of cryptocurrency, namely the Heterogeneous Autoregressive model of Realized Volatility – HAR-RV model. Despite the simplicity of the structure, the HAR-RV model shows good results in predicting the market prices of cryptocurrency. Taking into account that forecasting the changes in time series using regression models fails with unexpected spikes in market information, the Shannon entropy gets calculated, the values of which warn the researcher in advance about the growth or decline of the cryptocurrency rate. The article proposes to enhance the predictive properties of the HAR-RV model by calculating the Shannon information entropy for the studied time series. Conclusions and Relevance. Currently, despite the high volatility of the cryptocurrency, the changes in its market price can be predicted quite accurately. Cryptocurrency meets all the Austrian School's requirements for money, and in the future, it will be able to compete with fiat currencies significantly. The proposed method of forecasting the changes in time series can be used by analysts and traders concerning their stock, exchange, and money market activities.

In this work, the optical emission spectrum technique was used to analyze the optical emission spectrum of (CdO: Fe) plasma produced by laser Nd: YAG with a wavelength of (532) nm, a period of 10 ns, and a focal length of 10 cm in the energy range of (200-500) mJ. The electron temperature (Te) was determined using the method of line intensities ratio. Using the Saha-Boltzmann equation, the electron density (ne) was determined. Other plasma parameters such as plasma frequency (fp), Debye length (λD) and Debye number (ND) were also measured. The CdO: Fe (at a mixing ratio of X= 0.5.) plasma spectrum was observed for different energies. As a function of the laser energies, the changes in electron temperature and densities were studied.  The value of the electron temperature, at X=0.5, was (0.420 - 1.160) eV  for laser energy (200-500) mJ, respectively.

A Multi-Objective Task Offloading Optimization for Vehicular Fog Computing
Authors: Abdullah Sura Kh. , Jabir Adnan J.
Published: March 2022

Internet of Vehicle (IoV) is one of the most basic branches of the Internet of Things (IoT), which provides many advantages for drivers and passengers to ensure safety and traffic efficiency. Most IoV applications are delay-sensitive and require resources for data storage and computation that cannot be afforded by vehicles. Thus, such tasks are always offloaded to more powerful nodes, like cloud or fog. Vehicular Fog Computing (VFC), which extends cloud computing and brings resources closer to the edge of the network, has the potential to reduce both traffic congestion and load on the cloud. Resources management and allocation process is very critical for satisfying both user and provider needs. However, the strategy of task offloading to fog node in constraints of energy and latency is still an open issue. Several research works have tackled the resource scheduling problem in the field of VFC; however, the recent studies have not carefully addressed the transmission path to the destination node, nor has it considered the energy consumption of vehicles. This paper aims to optimize the task offloading process in the VFC system in terms of latency and energy objectives while taking the deadline constraint into considerations by adopting a Multi-Objective Evolutionary Algorithm (MOEA). Four different execution/transmission models are proposed where vehicle resources are utilized for tasks execution and transmission, and the well-known Dijkstra's algorithm is adopted to find the minimum path between each two nodes. The simulation results show that the models which involve the vehicles in the transmission process have reduced the latency and the total energy for the VFC system significantly in comparison with other models and the current state of the art methods.
Offline Handwritten Signature Verification Based on Local Ridges Features and Haar Wavelet Transform
Authors: Abdul-Haleem Mela G.
Published: March 2022

Multiple applications use offline handwritten signatures for human verification. This fact increases the need for building a computerized system for signature recognition and verification schemes to ensure the highest possible level of security from counterfeit signatures. This research is devoted to developing a system for offline signature verification based on a combination of local ridge features and other features obtained from applying two-level Haar wavelet transform. The proposed system involves many preprocessing steps that include a group of image processing techniques (including: many enhancement techniques, region of interest allocation, converting to a binary image, and Thinning). In feature extraction and analysis stages, a combination of local ridge features and other features obtained from the details of Haar wavelet subbands are extracted. Each wavelet sub-band image is fragmented into blocks with overlap and then the local features and wavelet energies are extracted from each block. Experiments were performed using a database of 600 signature prints collected from 100 persons, (i.e., 6 samples per person). The recognition accuracy of the system was the optimum (100%) using two decomposition levels. For verification purposes, the False Reject Rate for the system was (0.025%) while False Acceptable Rate was (0.03%) respectively.

The article shows the features of the cam with concave profile, the method of kinematic calculation of the pusher when it moves along a concave and rounded surface. The formula for determining the magnitude of the pusher velocity on the concave surface of the cam is refined. A method for determining the coordinate center for the radius of the concave surface of the cam is proposed. To increase the speed of the plunger and intensify the fuel injection process in high-pressure pumps of lowspeed diesel engines, it is recommended to use cams with concave profile. The calculation is performed using the Mathcad system of the stroke, speed and acceleration of the pusher depending on the angle of rotation of the cam shaft. Using the Mathcad program for cams with a concave profile, graphs of the pusher lift, changes in its speed and acceleration are constructed.

Authors:   Omsk State Transport University, Moskalev Yu. V.
Published: March 2022

The article has considered an approach to determining the minimum of the secondary winding coils turns of a transformer three-phase-multiphase phase number converter. Each phase of the secondary winding of the considered converter consists of three coils connected in series placed on three different rods of the magnetic circuit. In order to solve the optimization problem, the interior-point method is used. As an example, for a three-phase-five-phase converter has determined the minimum number of turns of the secondary winding, the total power consumed by the coils of the secondary winding is calculated. A vector diagram EMF of the coils of the secondary winding is constructed, explaining the formation of a symmetrical five-phase EMF system at the terminals of the secondary winding. Using the proposed approach, it is possible to design a transformer converter of the number of phases with a three-phase primary winding and a multiphase secondary winding, the number of phases of which is more than two.

Authors:   Omsk State Technical University, Khomchenko V. G.
Published: March 2022

The article discusses the kinematic scheme of the lever crank-slider mechanism of the third class, on the basis of which the executive mechanism of a mechanical non-clutch press is proposed under the patent for the invention (RF patent No. 2752399). Switching mode of operation of the press is carried out by moving the control slider from one stationary position to another. The kinematic parameters of the lever mechanism are assigned in such a way that in operating mode the law of motion of the working body of the press is close to the law of motion of the output link of the fourlink central crank-slider mechanism, and in the idle mode — the working body makes small movements (approximate stand) at full rotation of the crank. The analytical dependencies necessary for calculating the mechanism and the corresponding example are given.
