Authors:   The National Research Tomsk Polytechnic University, NADEZHDINA Yuliya Yur’evna
Published: November 2020

The relevance of the research. Natural conditions of the construction area of the Elegest–Kyzyl–Kuragino railway are extremely difficult. The territory under development is located in two regions: the Krasnoyarsk Territory and the Tyva Republic and crosses the complex mountain system of the Western Sayan Mountains. The climate of the territory under consideration is sharply continental, the average annual air temperature is –5.4 °С, the distribution of precipitation is uneven (northern part is 290–300 mm, southern part is 400–420 mm). Moreover, research is complicated by the length of the object, which is more than 400 km. For the Republic of Tuva, the projected railway will play an important role in the development of the fuel and energy complex, as well as in the development of the country’s economy as a whole. The study area is poorly studied, but it is characterized by the development of various geological processes, including permafrost. There is very little information on the distribution of permafrost, and it is scattered. The purpose of the work is to summarize and analyze information on the distribution of permafrost in the study area. The material examines the relationship of elevation marks with the spread of permafrost, and also gives a brief description of the geological conditions of the study area, relief, and possible dangerous geological processes. Methods of research. Generalization and construction of the map was carried out using AutoCAD and ArcGIS software products. As a result of the work, an analysis of literature sources on the distribution of permafrost and seasonally frozen rocks was carried out, information was generalized and a map of the distribution of permafrost by type (continuous, island, discontinuous) was constructed, and the boundaries of the distribution of permafrost were clarified in accordance with the altitude and type of permafrost.

Relevance. Ground ice is one of unstable components of the cryolithozone and occupies 400–600 km3 in total. Changes in the conditions of heat transfer of ground ice under the influence of external or internal factors can lead to the formation of thermokarst sinkholes, solifluction mudslides, cryogenic landslides and other dangerous cryogenic phenomena in the frozen rock mass. Various methods are used to study underground ice. You can distinguish the method of GPR. Its advantages are efficiency and high detail of measurements. However, the process of identifying underground ice based on the results of processing and interpreting ground-penetrating radar data is currently not formalized in the form of an algorithm. Purpose of the work. Rapid mapping of geocryological structures requires the development of an appropriate algorithm (sequence of formalized procedures) for the processing and interpretation of ground penetrating radar data. Methodology of the algorithm is based on the analysis of characteristics of GPR traces, the use of fast Fourier transform to calculate the spectra of GPR traces and further analysis of the results. Results of the study. The developed algorithm will make it possible to quickly study the structural features of the frozen rock massif with the release of layer ice. The algorithm was tested on the results of physical and computer modeling of ground-penetrating radar measurements of rock mass with ice included. Conclusions. The use of algorithms for processing and interpretation of ground-penetrating radar data for the operational mapping of geocryological structures of frozen rock massifs makes it possible to reasonably and rationally apply a set of measures to prevent the occurrence of unfavorable geotechnical processes or to reduce economic losses when negative geocryological processes are activated.

MSMEs – a mainstay for the developing economy
Authors: Kakkar Manisha , Kumar Amit
Published: November 2020

This research paper aims to understand all the factors preventing micro, small and medium enterprises from growing despite their great potential, the possible existence of any internal or domestic differences in the way the entrepreneurs from various Indian communities approach business. The question remains whether there are any external or domestic differences in their entrepreneurial orientations. The work also presents some policy-based suggestions to solve such issues that hinder the magnification potential of MSME units. The MSME units offer jobs to more than seven people. However, they do not grow because of many difficulties discussed in this paper. Due to the lack of opportunities, MSMEs are unable to attract foreign investments. MSMEs can stop the migration of young people coming from rural areas to urban cities if MSMEs get developed. MSMEs represent a high-priority sector of the growing and developing economy. Therefore, we need to focus on this sector to transform developing India into a developed country. This paper is an attempt to analyze the reasons for the difficulties of MSMEs.

Published: November 2020

This article analyzes the previously unknown aspects of using media technologies as tools for preventing the spread of HIV infection among young people in the Siberian region. Accordingly, the purpose of this article is to analyze the effectiveness of video cases in the prevention of HIV infection among young people. The authors rely on the idea of social prevention of dangerous diseases as a social institution that is functionally focused on the development, active assimilation and use of socio-cultural norms and skills, the risk of spreading diseases. The theoretical and methodological basis of the work is the approaches of well-known foreign scientists related to the issues of preserving society, stability of social systems, and coordination of the interests of the state and the individual. This article is based on materials of the monitoring study, which was conducted in 2019-2020 in the framework of preventive measures of HIV infection specialists of the “Center for Preventing and Fighting AIDS” in conjunction with volunteers. The authors of this article analyze the results of the survey: the questions were aimed at studying the awareness of young people about possible transmission routes, potential risk groups, clinical features of HIV infection and AIDS, as well as the awareness of young people about the HIV infection in general before and after preventive measures with the help of video sessions. This study makes a number of conclusions concerning the dynamics of students’ general awareness and their relationship to the HIV infection, as well as the effectiveness of media in preventing the HIV infection among the youth of the Republic of Khakassia. The results show that in the contemporary period of active usage of digital technologies, it is advisable to prevent HIV infection in the youth environment by using video cases. At the same time, educational organizations and educational institutions are the most optimal platform for performing HIV prevention work with young people. Finally, the main priority of HIV prevention should be to understand and understand the possibility of infection due to risky behavior of young people.

Authors: Maltseva Anna V. , Kasatkin Dmitrii M. , Temnyi Igor I.
Published: November 2020

International youth exchanges are one of the most relevant forms of international youth cooperation and an important aspect of state youth policy. This article attempts to draw public attention to the subjective aspect of youth exchanges by pointing out specific demands and requirements of modern generation students, who act as the main consumer of international youth programs. The Russian-speaking academic community generally lacks research on international youth exchanges and, specifically, on the youth’s demand for such exchanges. This article aims to characterize the current situation and to determine how the demand for international youth exchanges will develop in the longer term. This study also answers the question of who and why needs youth exchanges, and how to ensure that international programs are in demand. Finally, the study correlates opportunities for exchange development offered by the state with the youth’s demand for such exchanges, and examines the impact that exchanges have on young people. This work focuses on youth exchanges as a part of Russian state youth policy and on its youth cooperation with other countries. The emphasis is placed on students of St. Petersburg, one of the centres of international youth exchanges in Russia. The data was collected in January 2020 via an online survey in the social networks VKontakte and Facebook, as well as WhatsApp and Telegram messengers. It included 424 respondents aged 18 to 25. The study has revealed what students expect from and how prepared they are for international exchanges, as well as what possible risks and motivations are related to such exchanges. The obtained data has been correlated with the opportunities offered by the state. Based on the results of the study, a number of recommendations have been made. They can be useful for legislative and executive authorities, who are responsible for the legislation on exchanges, and for both for- and non-profit organizations, directly involved in organizing certain exchange programs.
Application of 3D Printing Technology in Bone Tissue Engineering: A Review
Authors: Feng Yashan , Zhu Shijie , Mei Di , Li Jiang , Zhang Jiaxiang , Yang Shaolong , Guan Shaokang
Published: November 2020

Clinically, the treatment of bone defects remains a significant challenge, as it requires autogenous
bone grafts or bone graft substitutes. However, the existing biomaterials often fail to meet
the clinical requirements in terms of structural support, bone induction, and controllable biodegradability.
In the treatment of bone defects, 3D porous scaffolds have attracted much attention in the
orthopedic field. In terms of appearance and microstructure, complex bone scaffolds created by 3D
printing technology are similar to human bone. On this basis, the combination of active substances,
including cells and growth factors, is more conducive to bone tissue reconstruction, which is of
great significance for the personalized treatment of bone defects. With the continuous development
of 3D printing technology, it has been widely used in bone defect repair as well as diagnosis and rehabilitation,
creating an emerging industry with excellent market potential. Meanwhile, the diverse
combination of 3D printing technology with multi-disciplinary fields, such as tissue engineering,
digital medicine, and materials science, has made 3D printing products with good biocompatibility,
excellent osteoinductive capacity, and stable mechanical properties. In the clinical application of
the repair of bone defects, various biological materials and 3D printing methods have emerged to
make patient-specific bioactive scaffolds. The microstructure of 3D printed scaffolds can meet the
complex needs of bone defect repair and support the personalized treatment of patients. Some of
the new materials and technologies that emerged from the 3D printing industry's advent in the past
decade successfully translated into clinical practice. In this article, we first introduced the development
and application of different types of materials that were used in 3D bioprinting, including metal,
ceramic materials, polymer materials, composite materials, and cell tissue. The combined application
of 3D bioprinting and other manufacturing methods used for bone tissue engineering are also
discussed in this article. Finally, we discussed the bottleneck of 3D bioprinting technique and
forecasted its research orientation and prospect.
The Potential Clinical Value of Curcumin and its Derivatives in Colorectal Cancer
Authors: Yao Zhaoying , Le Thi Ha , Du Qianming , Mu Huiwen , Liu Chao , Zhu Yubing
Published: November 2020

Background:

Curcumin, a naturally occurring polyphenol, possesses pleiotropic pharmacologic
properties, including anti-inflammatory and anti-oxidant activities. Epidemiological evidence suggests that
curcumin intake is associated with a reduced risk of Colorectal Cancer (CRC), highlighting the enormous
potential of this botanical agent in the prevention and treatment of CRC.

Objective:

We summarize the anticancer activity of curcumin and its derivatives in CRC.

Methods:

We conducted a literature review on the therapeutic effects of curcumin and its derivatives in CRC.

Results:

In this review, a summary of the activities of curcumin in the treatment of CRC regarding its
bioavailability, anticancer activity, modes of action, curcumin delivery systems have been provided based on the
researches from preclinical experiments. Also, we discuss the therapeutic effects of curcumin derivatives in CRC.
The human clinical trials that used curcumin or curcumin derivatives for the treatment of CRC are also
highlighted here.

Conclusion:

Curcumin possesses great potential as a chemopreventive agent in CRC. Moreover, emerging
evidence reveals that it can be an effective adjuvant to CRC therapy. To date, few studies have explored the anticolon
cancer activity of curcumin formulation and curcumin derivatives in vivo; therefore, more works are
needed to confirm their effectiveness. In clinical trials, curcumin treatment protocols (formulation, dose, and
duration) vary among studies. However, these trials consistently point out that the compound is well-tolerated
and safe, albeit with little consensus on its therapeutic efficacy.
Stress state of the foundations of buildings and structures
Authors: Agakhanov E. K. , Khidirov S. T. , Gabibulaev G. G.
Published: November 2020

Objective. Determination of the stress state of a ground base with a trapezoidal cutoff from the action of own weight, according to the conditions of equivalence of effects, is reduced to determining the stress state from the external surface load distributed according to the hydrostatic law.Methods. The problem of determining the stresses in the structure foundations at any degree of areas development of a plastic strain of the soil has a strict mathematical formulation, and similarity criteria can be obtained using a simpler construct of similarity theory. The simulation is performed by using similarity criteria based on which the model is executed, the loading conditions are determined, and the transition from the values measured on the model to the corresponding values of the full-scale structure is carried out. Similarity criteria can be obtained either with the help of similarity theory or with the help of dimensional analysis. An even greater effect of increasing the self-weight of a model made of transparent optically sensitive material can be achieved using the immersion method in conjunction with the centrifugal modeling method. If necessary, the stresses in the model area are fixed using the "freeze" method.Result. Using the equations system of the mixed problem of the elasticity and plasticity theory, and the scale method, similarity criteria are established for modeling stresses in the foundations of buildings and structures. Limitations on the choice of similarity multipliers for loose soils, the possibility of using the method of centrifugal modeling, as well as features of modeling connected soils are noted.Conclusion. A necessary condition for the similarity of the stress states of loose homogeneous bases in nature and the model is the equality of the similarity multipliers of the geometric scale and the force factor.

Authors: Mesropyan A. V. , Platonov E. A. , Rakhmatullin R. R.
Published: November 2020

Objective. The article deals with aspects of modeling the working processes occurring in marine thrusters of amphibious vehicles, taking into account the specifics of their operation. Methods. The methods of 3D modeling of propellers in CAD and CAE packages are applied, which can determine and optimize the parameters of ongoing work processes with reliable accuracy. Results. A mathematical construct is proposed that allows calculating the characteristics of marine thrusters of amphibious vehicles. The propeller is designed to provide more thrust compared to the original design, making it possible to increase the speed of movement on the water and reduce the radius of circulation when moving through the water. The calculated version of the propeller provides an increase in thrust by 36%, allows developing a high speed on the water, and significantly reduces the radius of circulation of the ferry-bridge machine when maneuvering on the water. Conclusion. The proposed option for increasing the speed and maneuverability of ferry vehicles on the water is the most effective and least expensive; a promising direction for further research to achieve maximum efficiency is the creation and verification of software, hardware, and methodological complexes for modeling the joint operation of the "marine thruster - hull - power plant" system.
Shaping the appearance of a long-range aircraft at the stage of developing a technical proposal
Authors: Gorbunov A. A. , Pripadchev A. D.
Published: November 2020

Objective. The process of designing a long-range aircraft, in particular at the preliminary design stage, involves comparing and analyzing a large number of design alternatives with specified performance criteria. At the same time, the problem of choosing the composition of rational design parameters is solved, which is an actual problem of the preliminary design stage of a long-range aircraft. Methods. The developed method allows determining the vector of parameters that provides rational characteristics for a given efficiency criterion. In this regard, the authors propose to introduce a global efficiency criterion - the takeoff weight of the long-range aircraft, and the specific criteria are the aerodynamic quality in cruise and the value of fuel efficiency. Results. In this formulation of the design problem, it is necessary to solve several interrelated problems, some of which are formalized, while others do not yet have a mathematical construct and software that allows automating the process. A distinctive feature of the proposed approach to finding a rational design solution is the use of statistical analysis methods in combination with methods of high-precision mathematical modeling, software-implemented in a single information environment using the Fortran V and C++ languages. Conclusion. The proposed method for selecting the composition of rational design parameters allows forming the appearance and providing the specified characteristics for its component elements at the early stages and stages of designing the long-range aircraft.
The Greek Middlebrow Magazine Μπουκέτο (1924‒46) and its Supplements
Authors: Gkogkou Despoina
Published: November 2020

This article introduces one of the first popular literary miscellanies published in Greece after the First World War, Μπουκέτο [Bouquet] (1924‒46). The first of its kind in the country, it led the way to a new type of periodical with subject matter ranging from serialized novels to short jokes, along with a modern layout featuring fine and plentiful illustrations. Drawing on Pierre Bourdieu’s theory of the cultural field, the article starts by showing that the magazine was a manifestation of middlebrow culture, combining commercial values with legitimate cultural aspirations and an eagerness to educate the masses. After situating the magazine in the cultural field of Greek periodical publishing and specifying its audience, the article focuses on its supplements, which followed the magazine’s publishing success. These were spin-off publications associated with the magazine, such as Βιβλιοθήκη του Μπουκέτου [Bouquet’s Library] (1924‒36), a series of translated classic novels, the annual Ημερολόγιον του Μπουκέτου [Bouquet’s Calendar] (1926‒33), and pamphlets or pull-outs sewn into the central pages of the magazine. The analysis draws attention to the characteristics, as well as the threads connecting them to the parent publication. The article traces the reasons that triggered the magazine’s subsidiary products and, by extension, the purposes they fulfilled, as well as the way they were used by the magazine throughout its lifespan in an attempt to create a name for itself and engage its readership.
Strolling the Streets to Discover the Cities: Cosmopolitan Collage in the Independent Magazine Flaneur
Authors: Anderson Natasha
Published: November 2020

The modern indie magazine Flaneur: Fragments of a Street, an English-language periodical published in Germany from 2013 onwards and distributed worldwide, examines a single street of a foreign city in each issue via a creative compilation of various visual and visceral materials in order to construct multimedia fragments into a cosmopolitan collage. Owing to its incorporation of sensate components, its focus on transnational networks, and its evocation of the figure of the nineteenth-century flâneur in order to bring urban environments to life for its widely dispersed readership, Flaneur offers a focal point in the diverse expanse of contemporary independent magazine publications. In order to capture the kaleidoscopic nature of modern life, the publication creates an amalgamation of poetic text, unusual layout, visual input, and haptic interaction within its printed pages. As a result, the interaction between mosaic content and multilayered flexibility within this modern, German magazine functions as the driving force in Flaneur’s goal to both build imagined communities across borders and establish an embodied, emotional reading experience.
Indie Magazines as Brands: Aesthetic Communication and Designing the Kinfolk Experience
Authors: Scheiding Oliver
Published: November 2020

Over the past years, Kinfolk magazine’s minimalist aesthetics has created a visual voice for a global slow lifestyle audience. Although Kinfolk has become a publishing phenomenon with many imitators, lifestyle magazines are frequently treated as light fare. Pioneering this particular genre of lifestyle magazine, Kinfolk fulfills a deeper purpose of helping readers define themselves. The magazine helps curate and perform lives and strives for authenticity, attraction, and positive valuation to generate short-term affective experiences and long-term cultural value. This article analyzes Kinfolk’s aesthetics as an architecture of relations assembling visual and textual page arrangements that are recurrently meant to be looked at more than read. While current studies associate Kinfolk’s slow lifestyle with Instagram’s blend of people and photography, this article seeks to demonstrate how editors, designers, and art directors have extended the visual personality of the magazine. In doing so, it will explore the magazine’s advanced aesthetic communication, establishing Kinfolk as the template for the millennial set and the culture of neomodernism.

In deze studie werd de invloed van het bedrijf, het seizoen en de gezondheid van de dieren op de samenstelling van consumptiemelk afkomstig van merries beoordeeld. Ook de fl uctuaties in de tijdwerden bekeken. Uit de resultaten blijkt dat er op een gegeven tijdstip een signifi cante variatie (p <0,0001) bestaat in vet, vetzuren, eiwit, lactoferrine, lysozyme, lactose en ureum tussen bedrijven onderling. Op bedrijfsniveau werden er grote signifi cante fluctuaties in de tijd vastgesteld voor de meestemelkcomponenten (p < 0,01 tot 0,0001). De fluctuaties tussen de verschillende bedrijven waren beduidend kleiner dan die binnen de bedrijven. Er kan besloten worden dat de samenstelling van paardenmelk weinig homogeen is, zowel tussen de bedrijven op een vast tijdstip als binnen de bedrijven in de loop van het jaar. Er zijn significante aanwijzingen dat seizoen, voeding, uiergezondheid en het niveau van wormbesmettingde samenstelling van deze melk kunnen beïnvloeden.

Published: November 2020

Dentro do programa de atividades que o Serviço de Aperfeiçoamento da Prefeitura do Distrito Federal pretende cumprir, foi dè logo cogitada a questão da necessidade de rever, para adaptação à atual realidade da Administração de Pessoal da Municipalidade, o regulamento referente a cursos de treinamento que, baixado pelo Decreto n.° 8.115, de 12 de junho de 1946, ainda hoje vigora, muito embora — diga-se de passagem — não tenha chegado à plenitude sua execução. Algumas tentativas nesse sentido houve — é certo — mas não passaram disso. Digna de registro, neste particular, foi a ação do extinto Departamento de Organização que, através da também extinta Comissão de Seleção e Aperfeiçoamento, planejou e chegou mesmo a instalar e executar alguns cursos de administração. A série de alterações profundas e freqüentes de ordem político-administrativa que iria então se suceder, caracterizando-se por uma descontinuidade administrativa, sem precedentes, provocaria o total colapso daquelas atividades que apenas se esboçavam. Houve depois a reintegração do órgão de aperfeiçoamento no exato âmbito de suas atribuições. Estamos nesta fase.

Mesmo assim, isolando-se êsses ciclos, cada qual oferece curioso panorama administrativo, tanto pelas influências recebidas __ acg0 da política européia sempre divergente — ou mesmo pelo caráter de subdivisão que a incipiente economia colonial determinava, não deixando, dêsse modo, que se formasse uma diretiva ou conduta homogênea sob um ponto de vista administrativo comum.

Measurements of the current-voltage characteristics of ion emission during the rupture of film samples of polyethylene terephthalate, polyimide, and polyphenylene ether in high vacuum have been carried out. Positive ions begin to be detected at a pulling potential of 100–200 V, and their number monotonically increases to saturation with increasing potential. Emission of negative ions is observed at a potential of << 200 V and in the range of 0–50 V has a resonance character, and the position of the resonance peaks is determined by the nature of the polymer. The discovered resonant nature of negative ion emission corresponds to the proposed physical mechanism of ion formation

Research has indicated that older adult participation in resistance training provides foundational strength for performance of activities of daily living. The purpose of this study was to investigate the effects of a six-week progressive resistance training intervention on functional fitness among community-dwelling older adults. From 2010–2015, twelve sessions of a six-week resistance training intervention included 95 community-dwelling older adult participants (37 male, 58 female; Mage=73.5+7.2). Resistance training interventions included bi-weekly, 1-hour sessions targeting all muscle groups. Assessments included arm curl, chair stand, back scratch, chair sit-n-reach, 2-minute step test, and 8 foot-up-and-go. The Wilcoxon Signed-Rank Test was performed to evaluate group differences between baseline and post-intervention. Significant differences between pre- and post-assessments were found for upper- and lower-body strength (z=6.81, p< .001; z=6.46, p< .001, respectively); upper- and lower-body flexibility (z=3.81, p< .001; z=4.85, p< .001, respectively), aerobic endurance (z=6.04, p< .001), and dynamic balance and agility (z=5.52, p< .001). The resistance training intervention resulted in significant improvements in functional fitness among community-dwelling older adult participants. Abbreviations: 1-RM, 1 Repetition Maximum

SAR-CoV-2 originated from China with first case reporting from Wuhan, has been declared as pandemic by WHO on March 11 2020, which has affected millions of people around the globe with 213 countries and territories infected worldwide. It has caused the death of around 0.6 million individuals with no specific or promising vaccines or treatment available until now to prevent COVID 19, which has been approved; this has led the world to a global crisis not only on the health front but also affected the economic sectors. Researchers across the globe are working around the clock with their level best to discover promising therapeutic approaches for COVID 19, but till now for the treatment, only 3 therapeutics have been approved, including dexamethasone in U.K. and Japan, Avigan in Russia, Italy, and China and remdesivir in Japan and Australia; also convalescent plasma therapy is seen to be effective in critical cases of COVID-19, however, there are limitations with the use of this plasma therapy like the time point of treatment, optimal dose as the dose may vary with number of patients the particular therapeutic effects of convalescent plasma therapy will be further explored in randomized clinical trials. Several complete multinational studies are investigating alternative therapies. More than 100 countries entered a cooperation to evaluate applicants for high-profile COVID-19 diagnosis with this most massive WHO's cooperation. According to WHO's information, there are 28 vaccine candidates under clinical evaluation, with 6 of them entering phase 3. This review emphasizes the allopathic approaches along with the Chinese herbal medicine for the prevention of COVID-19. This paper also includes a brief discussion on the vaccine and nutritional supplements.

Virtual patients and clinical decision-making skills: How students learn to diagnose depending on their psychological characteristics (Preprint)
Authors: Zalewski Bartosz , Walkiewicz Maciej , Guziak Mateusz
Published: November 2020

BACKGROUND

The process of conducting a clinical assessment is a highly complex task. Virtual Patient (VP) technology may be a useful tool to complement educational activities based on real patients and it is widely used in medical education.

OBJECTIVE

The goal of this exploratory study is to analyse which psychological characteristics of clinical psychology students are related to the effectiveness of learning clinical decision-making skills with the use of VP.

METHODS

Authors’ VP was used for measuring the ability to learn the decision-making in 29 last-year clinical psychology students by: negative vs positive aspects of a patient’s functioning, reactance, coping, stage of change, cognitive errors, adequacy of assessment data, and the quality of assessment. Psychological questionnaires were used for measuring student’s: need for cognitive closure; ability to achieve closure; beliefs of changeability on human traits; the level of hope, intelligence, positive vs negative affect, and academic knowledge.

RESULTS

Developing clinical decision-making with the use of VP is effective for students who have a higher ability to tolerate ambiguity and complexity of data. Students convinced of the changeability of human traits take into consideration more diverse data and the process of diagnosis requires the analysis of complex phenomena. Students with dominant negative affect seem to build diagnoses more carefully and make fewer cognitive errors than those with positive affect.

CONCLUSIONS

Our study indicates which properties of students support and which weaken the acquisition of the ability to make a diagnosis.

BACKGROUND

The COVID-19 global pandemic has disrupted structures and communities across the globe. Numerous regions of the world have had varying responses in their attempts to contain the spread of the virus. Factors such as public health policies, governance, and sociopolitical climate have led to differential levels of success at controlling the spread of SARS-CoV-2. Ultimately, a more advanced surveillance metric for COVID-19 transmission is necessary to help government systems and national leaders understand which responses have been effective and gauge where outbreaks occur.

OBJECTIVE

The goal of this study is to provide advanced COVID-19 surveillance metrics for Canada at the country, province, and territory level that account for shifts in the pandemic including speed, acceleration, jerk, and persistence. Enhanced surveillance identifies risks for explosive growth and regions that have controlled outbreaks successfully.

METHODS

Using a longitudinal trend analysis study design, we extracted 62 days of COVID-19 data from Canadian public health registries for 13 provinces and territories. We used an empirical difference equation to measure the daily number of cases in Canada as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R.

RESULTS

We compare the week of February 7-13, 2021, with the week of February 14-20, 2021. Canada, as a whole, had a decrease in speed from 8.4 daily new cases per 100,000 population to 7.5 daily new cases per 100,000 population. The persistence of new cases during the week of February 14-20 reported 7.5 cases that are a result of COVID-19 transmissions 7 days earlier. The two most populous provinces of Ontario and Quebec both experienced decreases in speed from 7.9 and 11.5 daily new cases per 100,000 population for the week of February 7-13 to speeds of 6.9 and 9.3 for the week of February 14-20, respectively. Nunavut experienced a significant increase in speed during this time, from 3.3 daily new cases per 100,000 population to 10.9 daily new cases per 100,000 population.

CONCLUSIONS

Canada excelled at COVID-19 control early on in the pandemic, especially during the first COVID-19 shutdown. The second wave at the end of 2020 resulted in a resurgence of the outbreak, which has since been controlled. Enhanced surveillance identifies outbreaks and where there is the potential for explosive growth, which informs proactive health policy.
