Updated Tourist Formalities as a Response to the COVID-19 Pandemic Challenges and New Terrorist Threats
Authors: TRIHUBA Tetiana
Published: December 2021

In the process of organizing and conducting tourist trips, travel companies and tourists perform a large number of tourist formalities. Failure to comply with at least one formality becomes an obstacle to crossing the border into the destination country, movement around the country and residence of temporary stay, and so on. The issue of their compliance during the pandemic has become particularly acute. Along with the existing tourist formalities, a number of new ones are being formed. The lack of a unified approach to the updated formalities creates significant obstacles to the resumption of Tourism. It is important to emphasize that the new tourist formalities and their analysis have not been reflected in scientific works. The article examines the impact of adding and changing tourist formalities on the development of Tourism and ensuring security, both in the host countries and in the countries of permanent residence of travellers (upon return). Much attention is paid to the peculiarities of the formation of new tourist formalities (medical and sanitary) in the countries that first started receiving Ukrainian tourists, the interdependence of changes in medical and sanitary tourist formalities with changes in the epidemiological situation is studied. Such studies allow us to identify which formalities are effective in stopping the spread of the pandemic, and which are duplicate, ineffective; they open up prospects for forming a unified approach for countries that accept tourists. At the same time, the article reveals the essence of the introduction of the ETIAS system. The article analyses the change in the security situation state, thanks to the implement of this system, and proves the need for further research on the impact of fulfilment of the ETIAS system requirements on stopping terrorist acts. A special stage for the development of domestic and international tourism was the implement of vaccination against COVID-19. There are new documents required for travellers — «vaccination passports». The article examines the impact of vaccination and the implement of an immune passport on the development of tourism during the pandemic and the post-pandemic existence of mankind. The directions, examples of implement, and stages of the process of recognizing immune passports as one of the main driving forces of tourist medical and sanitary formalities of international tourism are highlighted.

Published: December 2021

Based on scientific literature and online journalism, the article identifies theoretical and practical problems of formation and development of mentoring. It is revealed that theoretical dilemmas are caused by confusion in the conceptual apparatus of the specified direction of researches. The operationalization of terminology and the conducted semantic analysis of a number of definitions synonymous with mentoring: mentoring, coaching, tutoring allowed to formulate the characteristics of mentoring as a separate complementary category. Identification of the means used by mentoring, forms of communication, program results and their projection on the purposes of HR-management allowed to form a model of implementation of mentoring in hotel personnel management. In general, the theoretical principles and practical possibilities for mentoring outlined in the article outlined conceptual solutions for the professional development of staff in the field of HR hotel management, adapted to the conditions of crisis and fluctuating lockdown. It is noted that the practical barriers to the implementation of mentoring are related to cost savings of economic entities in the conditions of uncertain crisis framing, limited supply and lack of a consolidated business platform of mentors. Analytical tools and methodological tools used in the development of information sources in the field of HR management, as well as certain aspects of mentoring, created the preconditions for achieving the objectives of the study — to determine the essence of mentoring and justify its implementation in the practice of HR management. Methodical and practical recommendations for the implementation of mentoring by hotel business entities to ensure the formation of staff competencies and motivated development of labor potential. The need to create a digital consolidated platform of mentors’ proposals and conditions of interaction with clients (ment) has been identified. Prospects for further research are outlined, which are to develop a methodology for assessing the effectiveness of mentoring and its individual tools for HR management and other business processes of the hotel.

Using Immersive Virtual Reality to Examine How Visual and Tactile Cues Drive the Material-Weight Illusion
Authors: Naylor Caitlin Elisabeth , Proulx Michael J , Buckingham Gavin
Published: December 2021

The material-weight illusion (MWI) demonstrates how our past experience with material and weight can create expectations that influence the perceived heaviness of an object. Here we used mixed-reality to place touch and vision in conflict, to investigate whether the modality through which materials are presented to a lifter could influence the top-down perceptual processes driving the MWI. University students lifted equally-weighted polystyrene, cork and granite cubes whilst viewing computer-generated images of the cubes in virtual reality (VR). This allowed the visual and tactile material cues to be altered, whilst all other object properties were kept constant. Representation of the objects’ material in VR was manipulated to create four sensory conditions: visual-tactile matched, visual-tactile mismatched, visual differences only and tactile differences only. A robust MWI was induced across all sensory conditions, whereby the polystyrene object felt heavier than the granite object. The strength of the MWI differed across conditions, with tactile material cues having a stronger influence on perceived heaviness than visual material cues. We discuss how these results suggest a mechanism whereby multisensory integration directly impacts how top-down processes shape perception.

Published: December 2021

The interaction between cucurbit[8]uril (Q[8]) and chloramphenicol (CPE) was investigated using single-crystal X-ray diffraction spectroscopy, isothermal titration calorimetry (ITC) and UV–vis, NMR and IR spectroscopy. The effects of Q[8] on the stability, in vitro release performance and antibacterial activity of CPE were also studied. The results showed that CPE and Q[8] formed a 1:1 inclusion complex (CPE@Q[8]) with an inclusion constant of 5.474 × 105 L/mol. The intervention of Q[8] did not affect the stability of CPE, but obviously reduced the release rate of CPE in artificial gastric and intestinal juice; Q[8] has a slow-release effect on CPE. The antibacterial results showed that the minimum inhibitory concentration (MIC) of CPE and CPE@Q[8] toward Escherichia coli (E. coli) was 1.5 × 10–3 and 1.0 × 10–3 mol/L, respectively, and toward Staphylococcus aureus (S. aureus), the MIC was 2.0 × 10–3 mol/L for both CPE and CPE@Q[8]. Therefore, Q[8] enhanced the inhibitory activity of CPE against E. coli.

Published: December 2021

Until the end of the XX century, anchovy sprat was the leading object of marine fishing in the Caspian Sea. At the beginning of the XXI century, there was a mass death of this species, as well as an outbreak of the number of mnemiopsis comb - a powerful consumer of feed zooplankton. There was a redistribution of keel clusters in the sea. The main part of the fishing stock of keels began to be distributed in the Middle Caspian Sea. The main object of marine fishing has become an ordinary sprat. In recent years (2015-2020), there has been an increase in the number of anchovy sprats. The materials of keel surveys also confirm the annual growth in the number of juvenile sprats. This paper presents the results of recent years of observations, shows the dynamics of the number and biomass of the population, the parent part of the herd, total fertility. The efficiency of spawning and the survival coefficients of the generation in early ontogenesis are shown. Environmental factors that have a direct impact on the formation of the anchovy sprat stock are described.

Published: December 2021

The analysis of data on the conduct of fish-biological tests for the period 2016-2020 is presented at fish breeding plants of Primorsky and Khabarovsk territories on juveniles of chum salmon experimental granulated and extruded starter feeds, both with the use (compound feed V1M) and without the use of fermentolysate (compound feed V1M-BF). The highest average daily gains, as well as the average final weight of juveniles, were noted when dry fermentolysate was used as part of the starting compound feed. This is consistent with the data available in the literature on the positive effect of the products of partial protein fermentolysis at the initial stages of salmon development. When carrying out biological experiments, there is a high survival rate of fry from 97.5 to 99.9%, a low feed ratio for granulated feed with dry fermentolysate (0,64-0,80) and a protein utilization ratio (0,25-0,35).

APPROACH TO THE FORMALIZATION OF THE PROCESS OF CONDUCTING SPECIAL ACTIONS BY A SPECIAL FORCES UNIT USING THE ANALYTICAL-STOCHASTIC MODEL.
Authors: Kokoiko A.
Published: December 2021

The current realities of the military-political situation in the world comprise the emergence of a significant number of new contradictions of various natures between states and entire regions, and in some countries acute territorial, religious and ethnic confrontations that have led to a number of armed conflicts. In addition, international terrorism, drug smuggling, illegal arms trade and organized crime pose serious threats today. The emergence of these threats brings the necessity of drastic changes in approaches to resolving them. A significant share in the settlement of these conflicts belongs to the Special Operations Forces, which is the youngest and most advanced component of the Armed Forces of Ukraine. The authors identify one of the main problems that is the lack of a unified approach to the formalization of the process of conducting special actions.

The purpose of this article is to form a mathematical model of the process of conducting special actions by the unit of Special Operations Forces during the planning and conducting of special operation. The authors propose an approach to the formalization of the process of conducting special actions by a special forces unit, using an analytical- stochastic model.

Unmanned aerial vehicles (UAVs) allow effective solving the problems of reconnaissance, relaying information on targets to means of fire destruction and striking on any type of object. However, there are many problematic issues regarding the creation of a communication system for remote control of UAV of medium and long range, obtaining video information about reconnaissance objects in real time.

The methods allow to estimate the value of the deviation of the carrier frequency of the transmitter of the radio communication channel of unmanned aerial system (UAS) in the normal mode of its operation from the value of the prototype stated by the Developer based on the instrumental measurement of the average or assigned frequency of modulated radio emission.

The purpose of the article is to consider the methods, technical means and conditions of instrumental evaluation of the radio emission frequency of UAV‟s radio channels transmitters by means of radio frequency control.

This technique defines a set of procedures and rules for instrumental evaluation (measurement) of radio frequency of UAVs prototypes radio transmitters by means of radio frequency control in order to verify compliance of its parameters with the requirements of technical conditions or specifications for experimental aircraft.
CONSIDERATION OF THE "CONDITION-BASED" ALGORITHM OF AVIATION EQUIPMENT OPERATION WITH THE USE OF GROUND MEANS OF TECHNICAL CONTROL AND ON-BOARD MEASURING SYSTEMS IN THE STATE AVIATION OF UKRAINE
Authors: Kuzmich О. , Arkushenko P. , Andrushko М. , Haidak I. , Pashchenko S.
Published: December 2021

The article highlights the main aspects and features of the algorithm of aviation equipment operation "condition-based" with the use of ground technical means of control and on-board measuring systems and the formation of decision- making principles for further operation of aircraft.

To develop methods of technical diagnostics of any technical equipment, it is necessary to identify which parameters characterize its condition and reliability as well as to establish diagnostic criteria and limit values of the controlled parameters.

Depending on the nature of the parameters being controlled, there are parametric and physical methods of diagnostics. Based on the results of the diagnostics, we must get a straight answer: whether or not it is necessary to perform repairs or maintenance of the equipment being tested, taking into account the ensuring of failure-free operation before the next diagnostics.

Currently, a large number of different measuring equipment that can measure signals that meet the parameters of the object of control and diagnostics are successfully used to objectively determine the technical condition of aircraft.

The use of the laboratory for technical diagnostics of aviation equipment in conjunction with on-board measuring systems will provide an opportunity to make a quality technical diagnostics and reasonable conclusion to decide on further operation of the sample of aviation equipment. The use of mentioned laboratory will also predict the occurrence of failures of aviation equipment systems and units.

Only a comprehensive approach to the technical diagnostics of aviation equipment with employment of all means of technical control (ground, on-board) will prevent sudden failures of aviation equipment systems.

Authors: Surkov O. , Lobanov A.
Published: December 2021

Based on the results of the study, a scientific and applied problem was formulated, a hypothesis (multifactorial) was advanced, and partial scientific tasks were identified to develop a holistic methodology for strategic planning of the development of the Armed Forces of Ukraine based on capabilities.

The relevance of the study is due to the emergence of new problems in the field of defense and military development, a decrease in the objectivity of strategic decision-making in determining and adjusting the development strategy of the Armed Forces in the long term, and the effectiveness of strategic planning for the development of the Armed Forces as a whole through the introduction of capabilities-based planning methodology in the defense forces.

The requirements of modern regulatory legal acts of Ukraine regarding the introduction of planning based on the capabilities, functions of the Ministry of Defense of Ukraine and the General Staff of the Armed Forces of Ukraine, as well as the tasks of the Interdepartmental Working Group on the Defense Review (a temporary subsidiary body of the Ministry of Defense of Ukraine) are analyzed.

The reasons for the emergence of problems in the construction and development of the Armed Forces are investigated, as well as contradictions in the definition and adjustment of the strategy for the development of the capabilities of the Armed Forces for the long term are revealed. The strategic planning of the development of the Armed Forces and defense planning are differentiated according to the goal, results and responsibility between the subjects of planning.

The scientific and applied problem lies in the need to develop a concept of strategic planning for the development of the Armed Forces of Ukraine based on the capabilities, a set of special methods, techniques and approaches to determine and adjust the strategy for the development of the capabilities of the Armed Forces in the long term. A research hypothesis (multifactorial) about the conditions for achieving the effectiveness of strategic planning for the development of the Armed Forces of Ukraine on the basis of capabilities is put forward and partial scientific tasks are identified, which will be devoted to further research.

Published: December 2021

West Bengal has several leather industries and as such huge amount of leather are processed every year. The tannery effluents are discharged into the land and open water causing soil and water pollution respectively. Chromium is one of the most toxic inorganic contaminants which is well known for its carcinogenicity. Thus, our study focuses on investigating the bioremediation potential of common microflora isolated from tannery wastewater. In our study, Isolate 1 has the highest ability to reduce chromium (Cr6+) as compared to others. Isolate 4 has the highest protease, lipase and leather degradation activities. Isolate 1 shows the maximum keratinase activity making it an effective strain for keratinase production. Also, it has been found that pH 8 and temperature 40 °C was most suitable for keratinase production. Owing to the multidimensional ability of these two isolates, they were identified by 16S rRNA sequencing and it reveals that Isolate 1 and Isolate 4 belong to Bacillus cereus F4810/72 and Brevibacillus brevis F4810/72 respectively. Thus, this study establishes the role and efficiencies of these microorganisms in combatting pollution, particularly in the water bodies in which harmful chemicals leak regularly owing to improper waste management by various industries.

Natural bacterial strains with valuable technical properties are a vital biological resource for developing new biopreparations and rotating already known microbial preparations in the world market. This study describes a new natural strain B. pumilus 16, which was isolated from the rhizosphere of Cichorium. The strain was identified using morphological and physiological parameters, biochemical tests, and primers Pum-f. and Pum-r. Antibiotic sensitivity and antagonistic activity against Escherichia coli were determined by diffusion of discs and delayed antagonism methods, respectively. The new natural strain (like type strains) fermented arabinose, cellobiose, mannitol, mannose, salicin, sucrose, and trehalose, and gave a positive reaction to arginine dihydrolase, ONPG, Voges-Proskauer test. It also gave a negative reaction to inositol, raffinose, sorbitol, methyl-D-glucoside, inulin, and lecithinase. B. pumilus 16, unlike the test strains, was capable of fermenting citrate. Strain B. pumilus 16 was highly sensitive to cephalexin (37.9±0.7 mm) and enrofloxacin (25.7±8.9 mm); sensitive to ole-andomycin (17.1±1.9 mm), benzylpenicillin (18.5±1.2 mm), and monomycin (16.0±0.6 mm); resist-ant to oxacillin. By the agar blocks method (7.3±1.5 mm), a more pronounced antagonism of the new strain against E. coli was recorded than by the method of agar wells (5.3±0.6 mm). Due to the level of antagonistic activity, B. pumilus 16 was more effective than the type strains (two of which did not show an antagonistic effect). On the basis of this, the new strain can be recommended for inclusion in the bacterial preparation composition for the national economy.

A non-standard class of variational problems of Herglotz type
Authors: Martins Natália
Published: December 2021

In this paper, we extend the variational problem of Herglotz considering the case where the Lagrangian depends not only on the independent variable, an unknown function \begin{document}$ x $\end{document} and its derivative and an unknown functional \begin{document}$ z $\end{document}, but also on the end points conditions and a real parameter. Herglotz's problems of calculus of variations of this type cannot be solved using the standard theory. Main results of this paper are necessary optimality condition of Euler-Lagrange type, natural boundary conditions and the Dubois-Reymond condition for our non-standard variational problem of Herglotz type. We also prove a necessary optimality condition that arises as a consequence of the Lagrangian dependence of the parameter. Our results not only provide a generalization to previous results, but also give some other interesting optimality conditions as special cases. In addition, two examples are given in order to illustrate our results.

Graph labeling is a source of valuable mathematical models for an extensive range of applications in technologies (communication networks, cryptography, astronomy, data security, various coding theory problems). An edge $ \; \delta - $ graceful labeling of a graph $ G $ with $ p\; $ vertices and $ q\; $ edges, for any positive integer $ \; \delta $, is a bijective $ \; f\; $ from the set of edge $ \; E(G)\; $ to the set of positive integers $ \; \{ \delta, \; 2 \delta, \; 3 \delta, \; \cdots\; , \; q\delta\; \} $ such that all the vertex labels $ \; f^{\ast} [V(G)] $, given by: $ f^{\ast}(u) = (\sum\nolimits_{uv \in E(G)} f(uv)\; )\; mod\; (\delta \; k) $, where $ k = max (p, q) $, are pairwise distinct. In this paper, we show the existence of an edge $ \; \delta- $ graceful labeling, for any positive integer $ \; \delta $, for the following graphs: the splitting graphs of the cycle, fan, and crown, the shadow graphs of the path, cycle, and fan graph, the middle graphs and the total graphs of the path, cycle, and crown. Finally, we display the existence of an edge $ \; \delta- $ graceful labeling, for the twig and snail graphs.
Noise Management in Homomorphic Encryption Scheme: Analyzing of Algorithm

Homomorphic encryption is the Swiss army of cryptography. It allows to perform computations on encrypted data. this conjecture of processing on encrypted data was stated by [RAD78]. Until Gentry breakthrough in 2009, only partial solutions were offered. They deal with encrypted data with bounded functions in operations.Gentry raised the bound of number of operations by introducing a new method called the bootstrapping. This method allows to reduce the noise in the ciphertext and to perform more computing on it. Since Gentry's breakthrough, several improvements and several alternatives to the bootstrapping technique have been proposed to improve execution time and reduce resource consumption.  This article studies the growth of noise and the noise management strategy in homomorphic encryption. It also presents the trend of hoping strategy from 2009 to 2016. Through the DGHV, it shows the management of noise on a one-bit encrypted message.
Selection of Habitat-Enhancing Plants Depends on Predator–Prey Interactions

Shallow areas of drawdown reservoirs are often devoid of adequate fish habitat due to degradation associated with unnatural and relatively invariable cycles of exposure and flooding. One method of enhancing fish habitat in these areas is to sow exposed shorelines with agricultural plants to provide structure once flooded. It remains unclear if some plants may be more suitable than others to provide effective fish habitat. To determine the fish habitat potential of various crops, we performed a replicated tank experiment evaluating the selection of agricultural plants by prey and predator fishes with and without the presence of the other. We submerged diverse treatments of potted plants in outdoor mesocosms stocked with prey and/or predator fish and monitored selection of plant species, stem density, and stem height over 0.5-h trials. Prey fish selected the densest vegetation, and selection was accentuated when a predator was present. Predators selected the second highest stem density and were more active when prey were present. Prey schooling was increased by predation risk, suggesting that cover was insufficient to outweigh the advantages of increased group size. Our data indicate that the perception of cover quality is reciprocally context dependent on predator–prey interactions for both predator and prey. Applications of the two most selected plant treatments in this study could enhance structural habitat for both predator and prey fishes in reservoirs, adding to their already reliable functionality as supplemental forage crops for terrestrial wildlife.
