Planning of the Interregional Tourist Route in the Urals
Authors: Zyrianov Aleksandr I. , Zyrianova Inna S. 
Published: July 2021

Abstract
The article aims to attract the attention of geographers to the development of technology for the design of tourist routes. The world and Russian experience of designing long interregional tourist routes is considered. The authors’ approaches to route design are illustrated by the example of the Urals. Interregional tourist routes in Russia are actively developed with the support of the government. They are initiated by interacting regions and especially federal districts. Interregional routes are tours covering several adjacent regions or regions that are close not territorially, but thematically in tourist aspects. Such routes are quite different, but they have mainly cultural and informative goals as well as an excursion, transport and sometimes cruise style. Among all the interregional routes, the ‘Golden Ring’ and the ‘Volga-Kama’ river cruises are exemplary, among which the ‘Moskovskaya krugosvetka’ stands out due to the uniqueness of the ring shape of the route. The geographic features of the Urals are at the heart of the logical decisions for the preparation of the interregional tourist project ’The Great Ural Route’. The Urals have attractive, image, logistic and other opportunities for organising a large tourist route. A route should be developed for residents of the country and foreign guests, which will introduce the most striking and characteristic objects of the macro region as a whole. Moreover, the annular shape of the route is most preferred. It is advisable to lay the route in most of the Ural regions. It should include the main cities, landscapes of different natural zones, the most significant excursion sites and distinctive territories. Geographic route design technologies make it possible to make them relevant for a long time.

Abstract
This paper present the results of our project to develop the preliminary design of a jet trainer plane (JTP) with a two-person crew, the base version of which is intended for cadet training. We first consider the assumptions and requirements for the new aircraft, and review the parameters of existing aircraft designs in the similarly-purposed class. Next we argue for certain design choices, regarding the aircraft layout, cockpit configuration, wing location and wingform, tail scheme, and powerplant. The resulting aircraft design is calculated to have a maximum flight speed of 940 km/h, a ground-level rate of climb of 100 m/s, and a range of 1130 km. The plane’s take-off mass is calculated, in three approximations, at 2264 kg. Lastly we present the training plane’s geometrical parameters, general view, and master geometry.

Published: July 2021

After 2009, accredited Canadian engineering schools began to develop processes to map the Canadian Engineering Accreditation Board-Graduate Attributes(CEAB-GAs) to their curriculum and integrate ways to measure them. At around the same time, several Canadian universities embarked on a process to identifytheir own University-wide Graduate Attribute (UGAs). UGAs are assumed to be applicable across study disciplines; i.e. the university experience as a whole.To address the need to assess students on the basis of the CEAB GAs and the UGAs in the Faculty of Engineering and develop the basis for an integrated graduate attribute management system, an interdisciplinary team conducted a yearlong qualitative study with the purpose of exploringthe intersection of the UGAs with CEAB-GAs. The key objectives were to develop a mapping process between the two sets and to explore management strategies for assessing both sets of graduate attributes. Two independent teams performed the mapping exercise using a sequential mixed methods study design. A qualitative exploratory mapping study was followed by a quantitative aggregation of the mapping results. Integration of the qualitative and quantitative study results was completed as part of the interpretation of the results. Both forward and backward mapping took place. Results demonstrated that, although generic, UGAs may not necessarily capture specific professional program graduate attributes such as the CEAB-GAs. The study also highlighted the need for more revisions and updates of UGAs by including various stakeholders who can substantially contribute to implementation and assessment of UGAs.

Published: July 2021

In-person laboratories in undergraduate engineering provide students with tactile opportunities to build career-related skills, which are reflected in the graduate attributes of program accreditation criteria. TwoMechanical Engineering laboratory courses at the University of Alberta implemented live-streaming amidstthe abrupt and indefinite move to online learning due to the COVID-19 pandemic over the Fall 2020 term. A highly motivated and technically competent lab instructional team derived the necessary set-up of hardware, software, and personnel to implement pedagogical strategies that replicated the in-person experience with mechanical equipment as much as possible. This innovative approach enabled students to be involved in the demonstration of experiments in real time, interacting with teaching assistants and peers to ask questions and receive feedback. Students preferred live-streaming of labs as compared to pre-recorded videos.

Much attention is currently paid to the study of the antioxidant properties of various objects – individual antioxidants, dietary supplements, medicines, liquid plant extracts. Antioxidant medicines are widely used as the main or additional correction agents in the treatment of a number of diseases. Therefore, the study and development of procedures for determining the antioxidant activity is a prospective task for today.
Aim. To determine the contribution of different concentrations of ethanol to the level of the antioxidant activity (AOA) of ascorbic acid solutions by the potentiometric method.
Results and discussion. The different ethanol content in the solution had the following percent of the contribution to the value of AOA of ascorbic acid solutions – 1.85, 3.56, 4.89, 6.76, 7.63 % for 20, 40, 60, 80, 96 % ethanol, respectively. The linearity of the procedure was proven in the range from 0.039 to 0.31 mmol/L.
Experimental part. The object of the study was solutions of ascorbic acid prepared using ethanol of different concentrations – 20, 40, 60, 80, 96 %. Potentiometric measurements were conducted by a Hanna 2550 pH meter (Germany) with an EZDO 5010 combined platinum electrode. Weighing was carried out using an АN100 digital analytical balance (AXIS, Ukraine) with d = 0.0001 g. Ascorbic acid was purchased from Sigma Aldrich (≥ 99.0 %), K3[Fe(CN)6], K4[Fe(CN)6], NaHPO4, KH2PO4 were of analytical grade.
Conclusions. It has been found that ethyl alcohol affects the change of the potential in the electrochemical cell and the level of AOA of ascorbic acid solutions. The percentage of the contribution of different concentrations of ethyl alcohol to the AOA value ranges from 1.85 to 7.63 %. The approach and the formula for calculation that take into account the effect of ethyl alcohol on the final AOA result of the test sample of ascorbic acid in a water-alcohol solutions have been proposed. The results of this study can be used in the pharmaceutical and food industries to determine, assess and control the AOA level of dietary supplements, liquid extracts, tinctures, medicines, and alcoholic beverages.

Aim. To study the indicators characterizing the epidemiological profile of the population of Ukraine concerning HIV and AIDS in the dynamics of the years.
Materials and methods. Data from the Center for Public Health of the Ministry of Health of Ukraine were used. Both general theoretical (historical, analytical-comparative, systemic, logical, etc.) and applied methods (epidemiological, mathematical-statistical, etc.) were applied.
Results. It was found that during 2015-2019 there was an increase in the rates of HIV infection of the population, both sexually and parenterally (excluding data for 2017). In 2019, the number of cases of human infection through sexual contact increased by 27.1 % compared to 2015, and via parenteral infection – by 31.4 %. The trend towards a systematic decrease in the number of children born to HIV-infected mothers during the entire follow-up period was positive. In 2019, compared with the data for 2015, there was an increase in the number of HIV-infected adults by 3.1 %, while AIDS patients, on the contrary, decreased by 11.3 %. An important fact was a decrease in the number of HIV-infected children under 18 by 27.3 % and children under 14 by 27.6 % in 2019 compared to 2015. A negative trend was an increase in the number of deaths from AIDS-related pathologies among adults in 2015-2018, as well as among children under 18 years of age in 2019 by 18.0 %. Based on the results of the analysis of the structure of HIV-infected people by age, there was a systematic increase in the proportion (%) of adults (from 81.0 % in 2015 to 86.6 % in 2019). In addition, the number of adult patients per HIV-infected child under the age of 18 was increasing (2015 – 4.27 adult patients, in 2016 – 4.98 people, in 2017 – 4.91 people, 2018 – 5.39 people, and 2019 – 6.68 people).
Conclusions. The presence of positive trends in the development of the epidemiological profile of the population of Ukraine for HIV and AIDS requires not only financial support from the state and society in the future, but also the development and implementation of the appropriate social and educational projects aimed at preventing further spread of this infection among the population.

Published: July 2021

Project-based learning (PBL) allows students to identify and find solutions to real-world problems using inquiry-based learning. With the exception of Correll and Bornstein (2018), very little has been written about using PBL to redesign college and university Curriculum Resource Centers. The authors of this article used PBL in conjunction with the Association of College and Research Libraries (ACRL) Guidelines for Curriculum Materials Centers (CMCs) and the three themes for PBL success in higher education identified by Lee et al. (2014) to work with a small class of upper-level elementary education pre-service teachers to redesign an academic library Curriculum Resource Center.

Published: July 2021

Enquanto política de formação docente a ser executada sob o regime de colaboração entre a União e entes federados, o Plano Nacional de Formação de Professores da Educação Básica (Parfor) completou uma década. Mas sua continuidade foi tolhida pelo decreto nº 8.752/2016, enquanto seus cursos ainda estão vigentes e pesquisas sobre ele são realizadas. Os documentos aqui analisados ”“ teses de doutorado e relatório científico de um grupo de pesquisa ”“ apontam para uma riqueza de dados, Ã s vezes contraditórios, que nos tensionam a pensar dialeticamente a realidade dos cursos no âmbito do Parfor, considerando seus aspectos negativos, mas também suas potencialidades.
