Methodological Approaches Towards the Use of Inclusive Tourism as a Tool of Economic Development of Russian Federation

Introduction. The development of inclusive tourism should contribute not only to the higher accessibility of tourism services for people with specific needs, but also to development of the tourism industry in general as well as to development of national economy. However, in the existing literature the problems of development of inclusive tourism are often separated from problems of development of national economic development. The goal of the paper is to propose approaches for implementation of the potential of inclusive tourism to foster the growth of the national economy. Methods. The research is based on the general method of analysis and synthesis. From the theoretical point of view the research uses the ecosystem approach. Table methods are used to present the results of the research. Results. We demonstrate that the use of the potential of the inclusive tourism for the national economy requires inclusion of people with specific needs in the processes of value creation within the tourism industry development of new destinations, absence of opposition between different groups of customers of tourism services and ecosystem approach towards relations management between stakeholders of the tourism industry. The concept of a continuum of customers of tourism services based on the criterion of specific needs is proposed. Conclusion. Inclusive tourism should not be seen as opposed to traditional tourism. In addition, the inclusive tourism should not be viewed as exclusively socially oriented activity. The strategy of development of inclusive tourism should be built on the idea of considering it as an integral part of the tourism industry as a whole.

Machine learning assisted adaptive LDPC coded system design and analysis

AbstractThis paper proposes a novel machine learning (ML) assisted low‐latency low density parity check (LDPC) coded adaptive modulation (AM) system, where short block‐length LDPC codes are used. Conventional adaptive modulation and coding (AMC) system includes fixed look‐up table method, which is also called inner loop link adaptation (ILLA) and outer loop link adaptation (OLLA). For ILLA, the adaptive capability is achieved by switching the modulation and coding modes based on a look‐up table using signal‐to‐noise ratio (SNR) thresholds at the target bit error rate (BER), while OLLA builds upon the ILLA method by dynamically adjusting the SNR thresholds to further optimize the system performance. Although both improve the system overall throughput by switching between different transmission modes, there is still a gap to optimal performance as the BER is comparatively far away from the target BER. Machine learning (ML) is a promising solution in solving various classification problems. In this work, the supervised learning based k‐nearest neighbours (KNN) algorithm is invoked for choosing the optimum transmission mode based on the training data and the instantaneous SNR. This work focuses on the low‐latency communications scenarios, where short block‐length LDPC codes are utilized. On the other hand, given the short block‐length constraint, we propose to artificially generate the training data to train our ML assisted AMC scheme. The simulation results show that the proposed ML‐LDPC‐AMC scheme can achieve a higher throughput than the ILLA system while maintaining the target BER. Compared with OLLA, the proposed scheme can maintain the target BER while the OLLA fails to maintain the target BER when the block length is short. In addition, when considering the channel estimation errors, the performance of the proposed ML‐LDPC‐AMC maintains the target BER, while the ILLA system's BER performance can be higher than the target BER.

Three-dimensional reconstruction of light field based on cubic B-spline curve fitting

Fringe projection profilometry has been widely used in three-dimensional (3D) reconstruction. In this paper, we replace the camera with a self-made light field camera to achieve structured light field 3D reconstruction. Our self-made light field camera boasts higher resolution and lower cost with the ability to adjust spatial and angular resolution as needed. A novel 3D reconstruction method based on cubic B-spline curve fitting is proposed to directly fit the relationship between phase and 3D coordinates, and the look up table method is utilized to accelerate the entire calculation process. The experimental results demonstrate that the proposed method can accomplish 3D reconstruction of the structured light field under various viewing angles. Specifically, it has respectively reduced the computation time for phase and modulation intensity by 64.03% and 41.43%, and the reconstruction time is decreased by 32.99% without compromising the reconstruction accuracy.

Spreading behavior of biological SIR system of a COVID-19 disease through a fast Taylor wavelet based numerical algorithm

In this paper, we provide a unique, cost-effective numerical method for solving the SIR model of a COVID-19 disease using the method of Taylor wavelets and collocation technique. The model’s mathematical structure is represented by an ordered collection of ordinary differential equations that are nonlinear. We use the functional matrix of integration of Fibonacci wavelets to translate the given model into a set of computational equations, which we next simplify using the Newton–Raphson method. The given model is solved using the proposed method under various conditions to analyze the outcomes graphically and numerically as well. To demonstrate the efficiency and easy applicability of the method, we have also made a numerical comparison of the solution with some other methods in tables. The behavior of the approximate solutions of susceptible, infectible, and recovery curves under the proposed method is analyzed. MATLAB software is used to perform all the related calculations.

This approach maintains a high accuracy while limiting hardware size for suitability in sound rendering applications. Consequently, our proposed hardware-based inverse cosine calculation method is a valuable tool for achieving high efficiency and accuracy in 3D sound rendering.

Financial statements of companies as an object of investment valuation in the context of global economic uncertainty

Subject. This article examines the financial statements of companies in the focus of investment valuation as an effective mechanism for reducing risks in the context of global economic uncertainty. Objectives. The study aims to conduct an investment assessment of "young" companies that went public and entered the stock market after 2020 in the midst of the global pandemic. Methods. For the study, we used a systems approach, analysis, comprehensive investment assessment, and the table method. Results. The article presents the results of the investment evaluation of three companies that attracted the most interest among investors during the global pandemic, namely, Krafton Inc., Xpeng, and Airbnb Inc. Conclusions. Investment valuation of assets helps develop a competent investment strategy that can bring income in the future. In present-day developments, many investors pay more attention to some non-price indicators. However, if building a long-term investment strategy, one should rely on more objective indicators, for example, analysis of financial statements, ratio analysis, and investment evaluation.

Analysis of methods used to identify combustible gas and vapour-related factors contributing to explosions in the context of assigning explosion and fire safety categories to premises

Introduction . The authors have classified numerous publications, addressing the assignment of explosion and fire safety categories to premises, buildings and outdoor facilities, into the three groups: 1) sources of information that are in effect (including in-house and region-wide documents), sources that were in effect; 2) manuals and guidelines on category assignment; 3) publications that confirm (refute) or clarify some provisions, specified in regulatory sources. This article can be included into the third group of publications. Goal. Analysis of different methods, used to identify the value of Z factor; identification of strengths and weaknesses of each method, development of recommendations on the application of these methods. Objectives . The objective is to identify the substance-related factor contributing to explosions, use particular cases to demonstrate the efficiency of this or other identification method. Results and discussion. The analysis of Z factor identification methods, describing the contribution of vapours of highly flammable liquids to an explosion, has proven that three types of procedures can be used to find the Z factor value: the method of tables (that uses the maximal possible tabular value of Z = 1; for gases and aerosols Z = 0.5; for vapours of highly flammable liquids Z = 0.3); the computational method based on a pattern of three-dimensional gas and vapour spreading on the premises; however, this method, if applied, may involve a high probability of errors due to numerous conditions limiting its applicability; hence, the unexplainable value of Z may exceed 1. Besides, the computational method is extremely laborious. Its application requires the clarification of conditions for its use; the graphical method (based on the dependency graph of Z on the X parameter). This method is the simplest and the most reliable one. When the graphical method is used to find the value of Z , the excess oxidant ratio must be taken as being equal to one, and the Х parameter must be calculated according to the following formula: Х = 0.99 Р s.v / С st.c . Conclusions. The graphical method, used to find the value of Z , is simple and reliable. When the Х parameter is identified, the excess air ratio is used: φ = 1.9, which leads to the underestimation of Z , the vapour-related factor contributing to explosions. To prevent the unreasonable underestimation of Z , the excess air ratio must be disregarded or taken as being equal to 0.99.

CONTROL OF WORKING BODY OF AIRBORNE AIRCRAFT POSITIONING MECHANISMS BY MEANS OF STEPPER MOTOR IN STEP CRUSHING MODE

Step splitting control mode of the electric drives stepper motors working bodies of the positioning mechanisms of onboard aviation equipment is carried out by means of programmable controllers. From their output signals, pulse-wide signals are formed by means of drivers that control power transistors, which are included in the windings of a stepper motor.
 A simpler version of building control systems for stepper motors (SM) involves the use of programmable timers, which requires its reprogramming when changing the step splitting factor.
 In the process of step splitting the shape of the current in the winding of the SM approaches sinusoidal with an increase in the number of sine discretes stored in the controller's memory. However, in this case, the sine samples must follow at a higher frequency, which difficulties in programming them.
 There is a problem of finding new ways of programming in the controller's memory information about the changing shape of the supply voltage SM in the process of step splitting in order to ensure the maximum speed of the code and the minimum consumption of the processor time of the microcontroller.
 To solve this problem, it is proposed to specify information about the changing shape of the SM supply voltage not in the form of sine samples (table method), but the sum of the coefficients of the Walsh-Fourier series, the amplitudes of which depend of value of the step splitting factor.
 The Walsh-Fourier series is a natural basis for approximating the pulsed supply voltage of a stepper motor. Structural diagrams of digital and analog systems for stepper motors in the step splitting are proposed.
 In the digital control system, the Walsh matrix is entered into the permanent memory of the controller, the size of which is determined by the value of the minimum step splitting factor, and the column vectors of the coefficients of the amplitudes of the Walsh functions are entered into the random-access memory, each of which corresponds to its step splitting factor.
 The input controller sets the program for implementing the inverse Walsh transform to the control controller, as a result of which control signals for the driver are generated at the output of the DAC controller. As its output, control signals are generated for power transistors including in the windings of the stepper motor.
 In the analog control system, the main links are the Walsh functions generator and the block of summing coefficients. In the block of summing coefficients of each Walsh function is assigned an amplitude corresponding to a given step splitting factor, and then they are summed. As a result, a pulsed voltage is formed, which is fed to the input of the driver, as in a digital system. It is shown that an analog control system can be used to form low-frequency quasi- sine signals of high stability. They can be used in precision electric drives with high stability.

Intelligibility and Recognition of Announcer's Speech during Electric Acoustic Conversions in a Transformer

The purpose of the article is to outline the procedure and the results of the study of the influence of the distance from the sound source to the transformer on speech intelligibility and speaker recognition by voice during electro-acoustic conversion in a transformer. Of all the existing methods for measuring speech intelligibility and voice recognition, the objectified method of articulatory syllabary tables was used. The choice of the method is due to the fact that with a large number of dictated and, accordingly, adopted syllables, the influence of various factors is averaged out. Averaging also occurs if different groups of speakers and auditors take part in the tests. This is the objectivity of the articulatory method. Objective results can also be obtained by using speech to precisely reproduce sound combinations that do not have a semantic load, since when receiving words or phrases, it is possible to think out and restore the elements of the speech distorted by the communication path. The experimental procedure was determined. For the study, a transformer was used as an electroacoustic transducer, and a multifunctional search device ST031M “Piranha” was used as a control and measuring equipment. The selection of speakers and auditors was carried out for the research team. The selection was carried out among men and women between the ages of 18 and 30 who had no obvious speech and hearing impairments and were native speakers of the Russian language. The dependences of the values of the level of speech intelligibility and recognition of the speaker's voice on the distance between the sound source and the transformer are derived. The distances from the sound source to the transformer are determined, at which speech intelligibility corresponds to different quality classes according to GOST 16600-72.

FIRST-YEAR UNIVERSITY STUDENTS’ EDUCATIONAL/COGNITIVE MOTIVES FOR STUDYING IN RIGA AND SMOLENSK SAMPLES

For a successful pedagogical process, university teachers need to know the learning motivation of students, monitor it, and take into account its peculiarities while developing learning materials and choosing educational strategies. Especially great attention should be paid to the motivation of first-year students, as in the first months of studies freshmen face increasing difficulties sometimes negatively affecting their motivation. The paper presents some results of an international study of students’ motivation and focuses on one group of learning motives of first-year students, namely, on their Educational/cognitive motives. The aim of the study is to analyse and compare the Educational/cognitive motives of the first-year students at the universities of Riga and Smolensk, as well as to study the interrelationship between this kind of learning motives and the psychological atmosphere in the student group. In the survey carried out in December 2019, 129 students from EKA University of Applied Sciences (Riga, Latvia) and Smolensk State University (Russia) participated. The technique of diagnostics of learning motivation by 7 content scales was used for data collection. For studying the psychological atmosphere in the student group, the technique of 10 bipolar scales was chosen. Table method, descriptive statistics, analysis of statistical indicators, method of comparison, correlation analysis were used in the data processing. The data analysis shows that a few months after the start of studying, the learning motivation of the first-year students is at an average level. However, for successful training, it could and should be improved. In the Latvian sample, indicators for both the general learning motivation and Educational/cognitive motivation are slightly higher than in the Russian one. The correlation analysis reveals statistically significant correlations between the psychological atmosphere and motivation of students. The results of the study are useful for further investigation of students’ motivation and search of the ways to increase it.

Use of Personal Protection Equipment by Moscow Subway Passengers under Conditions of COVID-19 Pandemic

The Subway is the most important means of transport in Moscow. The active flows of passengers in the metro can contribute to the spread of infectious diseases with airborne and contact mechanisms of transmission, including the coronavirus infection COVID-19. The aim of the study was to assess the level of adherence to the use of personal protective equipment (facial masks, gloves) by passengers of the Moscow Subway. Materials and methods. A prospective study based on a visual assessment of passengers in a rolling stock of the Moscow subway, with division into cohorts of those using masks and gloves (K1), using only masks (K2), using masks in violation of the rules of use (K3) and not using personal protection equipment (K4) was conducted. Observations were carried out during the 42nd and 43rd weeks of 2020 in various subway clusters with a division in time into morning, afternoon and evening hours. Additionally, passengers were ranked into groups by occupation during the trip. Statistical processing included the identification of frequencies, their 95 % confidence intervals. To compare the significance of differences in the prevalence of features in paired groups, the methods of 4-field tables (χ2 Pearson) were used. Results and discussion. 18053 observations were validated, covering 61.3 % of stations. Men accounted for 54.7 % (9867). During the observation period, the following shares were established: K1 – 5.2 % (95 % CI 4.9–5.5), K2 – 51.9 % (95 % CI 51.2–52.7), K3 – 26.9 (95 % CI 26.2–27.6), K4 – 16 % (95 % CI 15.4–16.6). The level of adherence to the proper use of PPE is significantly lower among men. Land lines have the lowest proportion of passengers using PPE. Among passengers using electronic devices and paper media, a higher proportion of those wearing masks with violation of the rules of use, compared to passengers without activities, was established. Among passengers using electronic devices, the proportion of those using gloves is the lowest. Within two weeks of follow-up, a significant increase in the frequency of PPE use was revealed.

ПЕРФОРМАЦІЙНІСТЬ ДІЙ: МОЖЛИВІ ВІДПОВІДНОСТІ З ПОГЛЯДАМИ ДЖЕНІФЕР ГОРНСБІ ПРО ПРОЦЕС ДІЇ, ДІЇ, АКТИВНІСТЬ, ЗДАТНІСТЬ ДО ДІЙ

The article is devoted to outlining crucial aspects of defended approach to actions and agency in comparative with primarily J. Hornsby's views. The proposed approach is continuation of developed in the defended by the author candidate (PhD) and doctoral dissertations ideas. J. Hornsby is an outstanding classical philosopher of nowadays, her legacy is connected primarily with analytic tradition; and within it with philosophy of action and agency, philosophy of language, philosophy of mind, metaphysics, epistemology. Particularities of and relations between such important, but remaining to be vague notions as actions, events, facts, norms, values, evaluations were clarified (using the method of tables). These tasks disclosed ontological (metaphysical) modes actual for both philosophy of action and agency from one side and ontology (metaphysics) – from another. Ontology of action involves metaphysical processing (performing of action) and metaphysical results (achievements by action). The mentioned seem in accordance with J. Hornsby's views. Standard treatments of actions and agency were critically mentioned. The critics against them is due to missing or rather losing in and by them the need of the notion of an agent; because it is intention that causes an action. In the defended approach, as well as in J. Hornsby's theory, the role of an agent has priority. But the most interesting notion from her findings is proved to be trying or attempt to act. It was diversely described, used and shown promising. When successful trying to action coincides with this action. Trying to action is a reason for action. Trying to action does not represent, but present an action. Thus, justification of an action is directly within the action; because action performatively shows itself. Actions performatively validate correspondent events, facts, norms, values, evaluations.

Lingbao Huxin Pill Alleviates Apoptosis and Inflammation at Infarct Border Zone through SIRT1-Mediated FOXO1 and NF- κ B Pathways in Rat Model of Acute Myocardial Infarction

To investigate whether Lingbao Huxin Pill (LBHX) protects against acute myocardial infarction (AMI) at the infarct border zone (IBZ) of myocardial tissue by regulating apoptosis and inflammation through the sirtuin 1 (SIRT1)-mediated forkhead box protein O1 (FOXO1) and nuclear factor-κ B (NF-κ B) signaling pathways. Six-week-old Wistar rats with normal diet were randomized into the sham, the model, Betaloc (0.9 mg/kg daily), LBHX-L (0.45 mg/kg daily), LBHX-M (0.9 mg/kg daily), LBHX-H (1.8 mg/kg daily), and LBHX+EX527 (0.9 mg/kg daily) groups according to the method of random number table, 13 in each group. In this study, left anterior descending coronary artery (LADCA) ligation was performed to induce an AMI model in rats. The myocardial infarction area was examined using a 2,3,5-triphenyltetrazolium chloride solution staining assay. A TdT-mediated dUTP nick-end labeling (TUNEL) assay was conducted to assess cardiomyocyte apoptosis in the IBZ. The histopathology of myocardial tissue at the IBZ was assessed with Heidenhain, Masson and hematoxylineosin (HE) staining assays. The expression levels of tumor necrosis factor α (TNF-α), interleukin (IL)-6, IL-1 β, and intercellular adhesion molecule-1 were measured using enzyme-linked immunosorbent assays (ELISAs). The mRNA expressions of SIRT1 and FOXO1 were detected by real-time qPCR (RT-qPCR). The protein expressions of SIRT1, FOXO1, SOD2, BAX and NF- κ B p65 were detected by Western blot analysis. The ligation of the LADCA successfully induced an AMI model. The LBHX pretreatment reduced the infarct size in the AMI rats (P<0.01). The TUNEL assay revealed that LBHX inhibited cardiomyocyte apoptosis at the IBZ. Further, the histological examination showed that the LBHX pretreatment decreased the ischemic area of myocardial tissue (P<0.05), myocardial interstitial collagen deposition (P<0.05) and inflammation at the IBZ. The ELISA results indicated that LBHX decreased the serum levels of inflammatory cytokines in the AMI rats (P<0.05 or P<0.01). Furthermore, Western blot analysis revealed that the LBHX pretreatment upregulated the protein levels of SIRT1, FOXO1 and SOD2 (P<0.05) and downregulated NF- κ B p65 and BAX expressions (P<0.05). The RT-qPCR results showed that LBHX increased the SIRT1 mRNA and FOXO1 mRNA levels (P<0.05). These protective effects, including inhibiting apoptosis and alleviating inflammation in the IBZ, were partially abolished by EX527, an inhibitor of SIRT1. LBHX could protect against AMI by suppressing apoptosis and inflammation in AMI rats and the SIRT1-mediated FOXO1 and NF- κ B signaling pathways were involved in the cardioprotection effect of LBHX.

The Effect of Different Surgical Approaches of Ultrasound-Guided Quadratus Lumborum Block on the Analgesic Effect in Cesarean Section

Objective To study the effect of different surgical approaches of ultrasound-guided quadratus lumborum block on the analgesic effect in cesarean section. Methods 150 parturients underwent elective caesarean section in our hospital from February 2017 to February 2020 were enrolled in this study. They were divided into observation group and control group according to the method of random number table, with 75 cases in each group. In control group, anterior QLB was used, while in observation group, posterior QLB was used. The operation process was performed by the same anesthesiologist. If the injection situation was not ideal, the position of needle tip was timely adjusted. Both groups were given sufentanil 100 HQ/kg (diluted with 100 mL normal saline) and a single addition of morphine 50 mg (diluted with 100 mL normal saline) for self-controlled analgesia after operation. The postoperative time to first water intake, the time to first discharge from bed, hospital stay and satisfaction degree of labor pain were compared between the two groups. The numerical pain score (NRS) and visual analogue scale (VAS) scores of rest and movement at different time after operation were compared. The dosage of sufentanil and morphine in perioperative period and the occurrence of postoperative adverse reactions were compared between the two groups. Results The time to first water intake, the time to first discharge from bed and hospital stay in the observation group were significantly shorter than those in the control group (P &lt; 0.05), and the satisfaction score of analgesia in the observation group was significantly higher than that in the control group (P &lt; 0.05). The NRS score of observation group at TO, 1, 2, 3 and 4 after operation was significantly lower than that of control group (P &lt; 0.05). There was no significant difference in VAS score of rest and movement at 4 and 8 h after operation between the two groups (P &gt; 0.05); the VAS score of rest and movement at 12 and 24 h after operation in observation group was significantly lower than that in control group (P &lt; 0.05). The amount of sufentanil and morphine used in the perioperative period in the observation group was significantly less than that in the control group (P &lt; 0.05). The total incidence rate of adverse reactions in observation group was not significantly different from that in control group (P &gt; 0.05). Conclusion Both anterior and posterior QLB can provide analgesia after cesarean section, but posterior QLB can better relieve the postoperative pain of parturients, which is worth popularizing in clinic.

A Multimodality Information Synchronization Scheme for a Multisource Information System in the Electric Grid

A multisource and heterogeneous database is an important problem that disturbs the use of the electric power information system. The existing database synchronization scheme has some problems in practical applications, such as high resource loss and poor portability. This paper presents a high-efficiency database synchronization scheme for the electric power information system. The database is monitored, and its changes are captured by the shadow table and trigger method. Thus, data could be exchanged in trusted networks and nontrusted networks. In addition, a predetermined strategy is used to avoid data conflicts and ensure consistency and reliability of data synchronization. The above method is applied in the protection system of power networks. The results show that the synchronization scheme can effectively ensure the security of the system and has higher synchronization efficiency.
