THE PURPOSE. Charging infrastructure is one of the factors influencing the transition to electric vehicles, as the electric vehicles in operation are characterized by a small range and a long battery charge period. Today, the development of the charging infrastructure depends only on the networks of stationary charging stations, which also have disadvantages (high cost, lack of mobility, etc.). Therefore, the purpose of this work is to study the design features of mobile electric vehicle charge units (MCSEU) for the development of draft design documentation for the creation of a new MCSEU project. This issue includes the study of the world market of manufacturers of modern mobile chargers, the study of technical and operational features that are today presented to modern energy storage and storage systems.MATERIALS. The authors of the article processed and analyzed data on the current state of the charging infrastructure in Russia and the world, based on materials from Russian and foreign authors, as well as information on the development strategy of the electric transport industry in Russia and the world, in particular, data from Madison Gas and Electric.RESULTS. The obtained analytical results are one of the aspects that will be taken into account when developing mobile charging devices for electric vehicles. This mobile charger technology significantly expands the possibilities of using electric vehicles, in particular electric vehicles, and also solves various problems of the fuel and energy complex associated with autonomous power sources and distributed generation systems.CONCLUSION. The charging infrastructure is one of the factors influencing the transition to electric vehicles, as the electric vehicles in operation are characterized by a small range and a long period of charging the traction battery. However, this process will be long and in the near future networks of charging stations will be created, including mobile charging units for electric vehicles.

Published: January 2022

THE PURPOSE. The necessity of establishing emission standards for highly toxic substances with carcinogenic properties in the context of the implementation of new principles of state regulation of environmental protection activities at energy enterprises is substantiated and confirmed. The analysis of the features of the formation and burnout of carcinogenic polycyclic aromatic hydrocarbons in the flue gases of boilers during the combustion of coals in lowtemperature conditions of the furnace process is carried out. Based on the analysis, the total and partial indicators of the harmfulness of flue gases were calculated in order to assess and predict the overall toxicity of coal combustion products, taking into account the contribution of carcinogenic substances.METHODS. When calculating the overall toxicity of flue gases, a systematic analysis and generalization of experimental data on the content of carcinogenic and non-carcinogenic polycyclic aromatic hydrocarbons in the combustion products of low-power boilers was applied.RESULTS. As a result of the performed study, the contribution of carcinogenic and non-carcinogenic polycyclic hydrocarbons to the overall toxicity of boiler flue gases during the combustion of Azeysky, Mugunsky, Cheremkhovsky and Tugnuy coal was determined. It is shown that substances such as benz(a)pyrene, fluoranthene, pyrene and phenanthrene significantly affect the level of the total indicator of the harmfulness of combustion products from 38.8 to 53.6%.CONCLUSION. The obtained research results can be applied at energy enterprises at the stage of substantiating the introduction of regime-technological and environmental measures in order to develop measures to improve environmental efficiency through technological rationing of carcinogenic emissions.

Frequent Flyer Cost Estimation
Authors: Zhukov V. E. 
Published: January 2022

The marketing activity of a modern airline is quite diverse. Under the conditions of an oligopoly, airlines develop their business in competition for a passenger.In modern conditions in Russia, the use of dumping methods of the early 1990s is very ineffective. There are no weak airlines left on the long-distance air transportation market, and in regional markets large companies lose to small regional carriers due to the high cost of performing flights on large-capacity aircrafts of the airline’s fleet.Generally, non-price methods of competition come out on top. Flexible tariff policy, advertising, and high service in servicing passengers remain leading traditional methods of competing for a passenger.This article is devoted to the study of another marketing method for attracting passengers, or rather retaining passengers on the airline’s flights, which is development of bonus programs, frequent flyer programs. PJSC Russian Airlines (Aeroflot) was chosen as the object for the study. The subject of the research is the «Aeroflot Bonus» program.The objective of the study is to study the cost of the program. For research purposes, this is the value of the frequent flyer program point. The problem proposed to be solved is to determine the amount of expenses for implementation of the bonus program of frequent flyers. When solving the problem in its staging part, the assessment is not limited to direct costs associated with the costs of marketing efforts in the form of costs for organising a special advertising department, issuing bonus cards, software, and wages. The estimation refers also to indirect costs in the form of unreceived proceeds from free bonus tickets. Besides, a rough estimate has been made of the airline’s hidden costs due to an unpaid seat on the plane. The study conclusions indicate that hidden costs will be taken into account in calculating the cost of a flight and the bonus program has a right to exist.

ABSTRACTBullying is a negative behavior that many students do. This behavior occurs a lot in the school environment carried out by senior students against juniors. The individual's ability to control emotions is low causing behavioral disturbances, so they choose to do bullying behavior. One of the factors that influence bullying behavior is emotion regulation. This study aims to determine the relationship between emotional regulation and bullying in class XII students at SMA Negeri 2 Makassar. Respondents in this study were 202 students using a simple random sampling technique. This study uses a quantitative approach with data analysis techniques Spearman rank correlation and t-test. The study used a bullying scale and an emotion regulation scale. The results showed there was a significant relationship between emotion regulation and bullying (p=0.001, r=-0.230). Its means that the higher the emotional regulation, the lower the bullying in class XII students at SMA Negeri 2 Makassar and there are differences in bullying behavior based on gender. The implication of this research for students is that they need to improve their ability to regulate emotions to avoid bullying or other negative behavior.Keywords: Emotion Regulation, Bullying, Students.

Background: To describe the characteristics and outcomes of patients with a clinical diagnosis of COVID-19 and false-negative SARS-CoV-2 reverse transcription-PCR (RT-PCR), and develop and internally validate a diagnostic risk score to predict risk of COVID-19 (including RT-PCR-negative COVID-19) among medical treatment.
Case presentation: Herein, we report a 42-year-old male patient from myagdi district Nepal presenting with high grade fever, dry cough, headache and dizziness on the August 10, 2021 during second phase of COVID-19 pandemic. There is no history of hypertension and diabetes. He went for RT-PCR test at local COVID-19 screening center and reported as negative for RT-PCR test. After that he referred to Lumbini Zonal hospital for further evaluation. RT-PCT swab test was performed again and reported negative. On the chest X-Ray, there was opacity on both lungs and the patient was referred to cancer hospital for lung cancer screening. The patient underwent for HRCT chest and biochemical laboratory tests for further evaluation. The chest High Resolution Computed Tomography (HRCT) indicated ground grass opacity (GGO) with crazy paving a typical COVID-19 interstitial pneumonia. In the biochemical laboratory test, there were elevation in Leukocyte (Total WBC count), Neutrophil, Glucose, Bilirubin Direct, Bilirubin Total, SGOT/AST, SGPT/ALT and Lactate Dehydrogenase (LDH). There was low count found in Lymphocyte, Eosinophil and Monocyte. These laboratory parameters findings are typical sign of COVID-19 patients. Then patient was isolated and treatment of given according to COVID-19 treatment guidelines. On September 12, 2021, all diagnostic tests showed that patient recovered from COVID-19.
Conclusion: It is safe to suggest that a symptomatic patient with typical chest HRCT and lab findings for COVID-19 should be quarantined or isolated even with 2 negative RT-PCR tests.

Annotation. The level of subjective control may vary in different regions depending on social and economic living conditions, moral attitudes and level of education of the population. Circumstances such as age, gender and constitutional variability in the locus of control cannot be ruled out (although there is very little research on this issue). The purpose of the study is to conduct a comparative study of the typological delineation of the emotional-dynamic pattern in practically healthy Ukrainian women without and taking into account the somatotype. Primary anthropo-somatotypological and personality indicators of practically healthy Ukrainian women aged 21 to 35 of different somatotypes were selected from the database of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. Determination of the components of internality by J. Rotter in the modification of E. F. Bazhin, S. O. Golinkina and O. M. Etkind included the definition (sten): indicator of the scale of general internality of the level of subjective control, indicators of the level of subjective control in the industry achievements, failures, family relationships, educational (professional) relationships, interpersonal relationships, health and disease. Statistical processing of the results was performed in the license package “Statistica 5.5” using non-parametric evaluation methods. The reliability of the difference between the values between the independent quantitative values was determined using the U-Mann-Whitney test. There was a lower level of general internality and subjective control in the field of achievement in mesomorphic women compared to women without taking into account somatotype and women of other somatotypes. According to the scale of internality in the field of failures in women without taking into account somatotype, endo-mesomorphs and representatives of the middle intermediate somatotype, the most developed sense of control over negative situations and the tendency to blame themselves for trouble compared to mesomorphic women. It is characteristic that in the sphere of family relations this image emerges especially clearly in mesomorphic women; they consider their partner, not themselves, to be more responsible for the events of family life. Women of intermediate somatotype compared to women without somatotype and women mesomorphs and ectomorphs have a higher level of internality in the field of interpersonal relationships. The level of subjective health and disease control in endo-mesomorphic women is significantly lower than in ectomorphic women. Thus, the level and various parameters of subjective control can be used as personal markers of the studied somatotype, which will create optimal and most individualized recommendations for psychological support, adaptation and coping strategies.

Published: January 2022

Objectifs et contexte : L’arrivée des tests de panel de gènes a augmenté la complexité de la communication en consultation d’oncogénétique. Une attention quant à l’impact de cette communication sur les préoccupations et les besoins d’aide psychologique s’avère d’autant plus indispensable. Cette étude vise à en quantifier le type et l’ampleur, avant et après la communication du résultat de test génétique, chez des femmes s’adressant à la consultation d’oncogénétique pour réaliser un test de susceptibilité au cancer du sein ou de l’ovaire en Allemagne, Espagne et France.
Participants et mesures : Parmi les 752 personnes invitées consécutivement à participer à cette étude, 646 (86 %) ― dont 510 (68 %) atteintes d’un cancer du sein―ont répondu à un questionnaire (PAHC (Psychosocial Aspects of Hereditary Cancer)) portant d’une part sur les préoccupations spécifiques à la démarche en oncogénétique et d’autre part sur leurs besoins d’aide psychologique ; questionnaire proposé après la consultation initiale d’oncogénétique initiale (T1) et, pour 460 (61 %) d’entre elles, deux mois après la communication du résultat du test (T2).
Résultats : Soixante-dix-neuf (17,2 %), 19 (4,1 %), 259 (56,3 %), 44 (9,6 %), 59 (12,8 %) femmes ont reçu respectivement les résultats suivants : un variant pathogène sur BRCA1/2 ou sur autre gène à risque élevé ou modéré, un résultat négatif non informatif, un résultat négatif vrai, ou la présence d’un variant dont la signification clinique est incertaine (VUS). Le type de préoccupations et les besoins d’aide psychologique se sont révélés variables selon les pays. Cependant, globalement, les préoccupations les plus fréquentes (> 70 %) étaient relatives à la perte d’un proche familial par cancer, et les moins fréquentes (< 5 %) relatives au soutien des proches. La plupart de ces préoccupations persistent deux mois plus tard, à la suite du résultat de test génétique. En revanche, le besoin d’aide psychologique a globalement diminué sur le plan statistique, excepté, selon le pays, pour les préoccupations familiales/sociales, les difficultés émotionnelles ou les aspects pratiques.
Conclusions : Dans notre étude portant sur des femmes issues de trois pays européens s’adressant à la consultation oncogénétique en vue de réaliser un test de susceptibilité au cancer du sein ou de l’ovaire, la plupart des préoccupations liées à la situation génétique persistent deux mois après la communication du résultat de test, et les besoins d’aide psychologique se manifestent surtout dans le champ des relations et des émotions.

Published: January 2022

Background: Functional appliances such as Bionator have been used to treat Class II malocclusion. The purpose of this study was to compare the skeletal, dental and soft tissue effects of Bionator appliances with Multi-P (a newly developed appliance) in the treatment of Class II malocclusion.
Subjects and methods: 45 class II children were chosen and randomly assigned to either the Bionator or Multi-P treatment group. After excluding 13 patients from the study, 21 patients in Bionator and 11 patients in Multi-P group have participated in the study. Lateral cephalograms were analyzed at the beginning (To) and at the end of treatment (T1) to evaluate the changes in both groups. The paired t.test and Levenâ€™s test were enrolled for statistical analysis.
Results: Reduction of ANB angle was detected in both treatment groups. The Bionator group underwent insignificant greater mandibular advancement as measured by the SNB angle. (p= 0.737) The mandibular plane angle increased insignificantly in both groups. (p> 0.05) The inclination of upper incisors decreased significantly in Multi-P group. (p= 0.042)
Conclusion: Both appliances are effective therapeutic means for class II treatment associated with mandibular deficiency and may lead to normalization of the dentoskeletal parameters at the end of the treatment.
