Published: May 2022

One of the promising applications of nickel hydroxide is electrochemical electrochromic devices. To significantly improve the characteristics, the role of polyvinyl alcohol (PVA) in the synthesis and structure of composite Ni(OH)2-PVA films was investigated by studying the effect of its concentration (30, 40, 50 g/l) and polymerization degree (17-99, 24-99, 30-99 types). Adhesion was investigated visually, and electrochemical and electrochromic properties – by cyclic voltammetry with simultaneous recording of optical characteristics. It was shown that at a concentration of 30 g/l, the film peeled off and had weak electrochemical and electrochromic properties. The presence of two cathodic peaks (E=500–510 mV and E=560 mV) on the cyclic voltammetry showed the presence of nickel hydroxide in the PVA matrix and nickel hydroxide with adsorbed PVA. This indicates the dual role of PVA as a surfactant and as a template. At low concentrations, the role of PVA as a surfactant prevailed. Increasing the concentration led to an increase in the film characteristics by strengthening the role of PVA as a template: at 50 g/l, the film did not peel off and has good electrochemical and electrochromic characteristics.
It is shown that at a low degree of polymerization, PVA (17-99 type) mainly played the role of a surfactant but was also a template. The film cracked and had mediocre characteristics. The use of medium polymerization PVA (24-99 type) gave a film with high adhesion, electrochemical and electrochromic characteristics. It is shown that in this case, PVA performed the function of a template, there was only one cathodic peak on the voltammogram at E=500–510 mV. It was found that the use of PVA with a high degree of polymerization (30-99 type) led to a significant deterioration of the characteristics, including complete peeling of the film. This is probably due to the loss of PVA in the film

Published: May 2022

The article proposes a new approach to solving the problem of biofouling at the facilities of the circulating cooling system of the Zaporizhzhia Nuclear Power Plant (ZNPP) by regulating hydrobiological studies. In the course of the studies, 4 species of hydrobionts were found that formed massive fouling on water supply facilities: filamentous algae Oedogonium sp. and Ulotrix zonata with a total biomass of 123.6±18.44 g/m2, tropical molluscs Melanoides tuberculata and Tarebia granifera of the Thiaridae family with a biomass of 20.09 g/m2. The shells of dead mollusks drifted along the pipes of the circulation system with the flow of water and interfered with the operation of pumping stations. Also, the blue-green algae Microcystis aeruginosa, which dominated the phytoplankton of the cooling pond, belonged to the potential bio-hindrances. The hydrobiological regulation was developed with the aim of timely detection of hydrobionts capable of active reproduction and creation of biological obstacles. It provides for four types of monitoring: current (operational), extreme (control), deployed (research) and background (hydrobiological monitoring of the Kakhovka reservoir in the zone of influence of waste warm waters). For each type of monitoring, the subjects of control (a group of hydrobionts), control parameters (species composition, abundance, biomass) and frequency of control are determined. The regulation of hydrobiological monitoring makes it possible to minimize the consequences or prevent the occurrence of accidents and emergencies in the operation of the ZNPP cooling circulation systems associated with biological obstacles, and can be used as an example for solving similar problems at other power facilities. The article also contains practical recommendations for improving the ecological state of the cooling pond and preventing the massive development of dangerous aquatic organisms by introducing biomeliorator fish with a different food spectrum into the reservoir

This paper considers the task of ensuring the energy and environmental security of regions under the conditions of shortage of traditional energy resources. The method of expert assessments has been applied to justify the choice of types of acceptable energy resources that provide an increase in the relative energy supply of the territories of the regions.
A list of factors from 6 groups has been devised and compiled that includes 27 indicators characterizing the technological, environmental, and other consumer characteristics of energy resources available for use.
The maximum and minimum values of the indicator scores, the permissible intervals for their change, and the weighting coefficients that assess the importance of the indicator in the list have been determined.
The method of expert assessments is supplemented by a random number generator for the formation of an information field on the values of the characteristics of energy resources and statistical processing of data on acceptable energy resources under the conditions of the considered regions.
A quantitative comparative analysis of available energy resources and technologies based on them was carried out. It is proposed to use the acceptability index and the environmental conservation index as a criterion for the preference of a resource. Index values equal to or greater than 1 indicate resource preference. It is shown that for the base region under consideration, such resources are nuclear, solar, wind, and hydropower.
The method of expert assessments makes it possible to get an objective idea of the acceptability of using a certain energy resource to ensure energy security, taking into consideration its environmental impact in a particular region of the country.
A quantitative comparative analysis of the state of the existing structure of energy resources in the region and their availability has been carried out.
To conduct a comparative analysis of acceptability by indicators and types of resources, a graphical and analytical methodology was used. The reliability of the results obtained was assessed using a concordance coefficient.
The results could be useful for devising projects for the development and ensuring the energy security of the regions in the context of reforms

This paper considers an approach to resolving referential relations when extracting information from a text. The proposed approach is an attempt to integrate the multifactorial model of the activation coefficient with the approach to resolving the referential ambiguity of the text when replenishing the ontology. The found objects are compared based on an assessment of the proximity of attributes and relationships of objects. An ontological interpretation of relations and measures of similarity of attributes based on a multifactorial model is proposed. This model is distinguished by the fact that it makes it possible to introduce the concepts of "rhetorical distance", "linear distance", "animation", "distance between paragraphs", and "syntactic and semantic role of the antecedent". A multifactorial model is proposed, which is a necessary and sufficient component for the purpose of explaining the measure of similarity of referents for choosing the best applicant. The counting system and its modification were revealed by trial and error; the work was carried out until the selected numerical weights began to explain all the available material. The current study also examines the factors of choice of reference devices that make it possible to work with complex sentences and texts. Moreover, examples of finding a measure of proximity in a multilingual system for the Kazakh, Russian, and English languages are offered. For the current paper, texts in the Russian, English, and Kazakh languages were used as a source for practical tasks. The texts were selected using news articles on the Internet sites where translations into other languages, including those named above, were offered.
The authors of this study have done massive practical work, which confirms the correctness of the thesis they are considering

Benign breast disorders are usually hormone induced and therefore usually seen in the reproductive period of life with dramatic fall in incidence after menopause. As compared to breast cancers, benign breast lesions are 10 times more common.

The aim of the study was to determine the spectrum and incidence of various benign breast diseases in female patients attending our institute and to compare the results with those of other studies.

Material and methods: 80 cases of benign breast diseases which were clinically diagnosed and confirmed pathologically or radiologically were subjected for therapeutic interventions and the results were analysed.

Results: In the present study of 80 cases, the age group most affected by benign breast diseases was 21-30 years. 63 patients (78.8 %) presented with lump in the breast and 23 patients’ common symptom is pain. In most of the cases of lump had duration between 7-12 months (38.8 %), pain for 1-5 days (13.8 %), discharge for 0-5 days (11.3 %). Both breasts were involved in 6 cases (7.5 %) whereas right and left breasts are equally involved in 47 cases each (46.25 %). Most of the patients were nulliparous (46.3 %) followed by multiparous (38.8 %) and uniparous (15.0 %). Fibroadenoma constituted in 53.8 % of patients (44 cases), breast abscess constituted 21.25 % (17 cases). The most commonly affected age group was 21-30 years. 63 patients (78.8 %) presented with lump in the breast and 23 patients presented with pain. HRUSG findings correlated with that of clinical diagnosis in 70 cases. 60 cases underwent core biopsy, and in 41 cases (68.33 %) there were fibroadenoma and 7 cases (11.66 %) fibro adenosis. 59 cases (73.75 %) underwent excision, and 18 cases (22.5 %) incision and drainage.

Conclusion: The most common benign breast disease was fibroadenoma. Most common age group affected with benign breast disease was 21-30 years. 88.7 % of clinical diagnosis, 90.3 % of radiological diagnosis, 93.3 % of core needle biopsy diagnoses were correlating with the histopathology diagnosis

Authors: Yunger Vitaly , Hbur Zoryana , Krylova Iryna
Published: May 2022

Highlights the essence of the concept of “self-management” and provides its author's interpretation. The goals and objectives of self-management in general and separately in the field of health care are considered. It was found that in order to effectively manage the staff of a health care institution, the manager, first of all, needs to know the science and art of self-management. General and local principles of science and practice of self-management are indicated.

The aim of the article is to develop and analyze the main features of self-management as the basis of success of a modern health care manager.

Materials and research methods are general scientific research methods such as systems analysis, comparison, generalization, swat analysis, forecasting. Studying the already studied components of the selected topic, such research methods as generalization, comparison, systems analysis were used. The basis for the study were the works of domestic and foreign scientists.

Results: the article establishes that self-management helps the leader: rationally organize their work and the work of their subordinates; realize professional and life goals; avoid stressful situations; increase efficiency; enjoy the work done. An analysis of the scientific literature has led to the conclusion that strong leadership is important to ensure the success of any medical institution. A manager who pays due attention to self-development is the key to the success of a healthy atmosphere in the team. Research indicates a high level of professionalism and creativity achieved by managers only when they have a need for professional self-development, self-improvement, as well as when they show a motivational and value attitude to themselves as a subject of medical activity.

Conclusions. Summarizing the above, it should be emphasized that self-management certainly affects the development of the modern manager of health care, so the following suggestions for the implementation of this method: to overcome administrative barriers to maintaining old management methods; to avoid problems caused by the inertial nature of public consciousness; reduce the level of conflict in the team; to overcome differences in professional competence; instill immunity to the fear of sanctions of the team - ridicule, overt and covert condemnation, ignorance
Structural changes of brain vessels in cardiosurgery patients with postoperative stroke
Authors: Mankovskyi Dmytro
Published: May 2022

Hypoxic-ischemic lesions of the brain of cardiac surgery patients as a leading factor in stroke have been studied. The importance of prolonged thrombosis, embolism, which exacerbate the general degenerative changes in the central nervous system is recognized.

The aim of the research – to study the morphological changes of the vessels of the brain of cardiac surgery patients with postoperative stroke on the background of hypoxic-ischemic complications.

Materials and methods. Pieces of cerebral vessels were subjected to microscopic examination. Histological sections were stained according to Van Gieson.

Results and their discussion. The study of the structure of the vessels of the brain of persons who were in the group intact to neurological pathology control, showed the presence of anatomical and functional changes that are fully consistent with the sex-age norms of postnatal human ontogenesis.

The drugs of the clinical observation group contained signs of pathological changes characteristic of hypoxic-ischemic disorders. It is obvious that their appearance and intensification contributed to the development of ischemic stroke. Structural and functional changes mainly concerned the vascular walls, their layers, paravasal spaces, the blood system as a liquid phase, in fact. Endothelial layer with signs of desquamation. Endothelial cells are characterized by signs of hyperchromia of the nuclei, the shift of the latter in the direction of one of the poles of the cells, the appearance of heterochromatin. Contacts between cells are weakened, defects are visible in the surface layer. Perovascular edema, which is formed in the case of increased permeability, leads to a certain isolation of individual vessels from the surrounding tissues, followed by the development of hypoxia. Defects of the wall layers lead to the activation of the migratory properties of platelets, encourage the appearance of megakaryocytes, erythrocyte thrombi, which are in close contact with the endothelial layer of blood vessels. On histological specimens, brick-red blood clots abundantly cover the damaged inner layer of vascular walls, sometimes completely filling their openings. Over time, defects in the layers of the walls are accompanied by thrombosis, inflammation, edema.

Conclusions. Hypoxic-ischemic brain lesions in cardiac surgery patients play a leading role in stroke. Priority is given to hypoxia, which contributes to ischemia, trophic disorders, atrophy, necrosis, necrobiotic changes. The latter are the organic basis of pathogenetic patterns of focal cerebral infarction (with progressive destruction of brain cells, its vessels, the development of prolonged thrombosis, embolism, increased general degenerative changes in the central nervous system)

Authors: Kholodniak Olena , Kovalenko Sergiy
Published: May 2022

Acyl isothiocyanates and their functional derivatives (acyl thioureas and acyl thiosemicarbazides) are an important group of organic compounds that are widely used in the synthesis of heterocycles and in chemistry as catalysts, ligands, colorimetric hemosensors, etc. In recent years, there has been an increased interest towards this class of compounds as promising biologically active compounds, especially since the latest advances in medicinal chemistry for them are not sufficiently studied.

The aim. To summarize and systematize information for the last 10 years on methods of synthesis and biological activity of substituted acyl thioureas and acyl thiosemicarbazides.

Materials and methods. Web-tools for finding scientific information (Reaxys, Scopus, Google Scholar, ScienceResearch, SciFinder, Web of Science, etc.).

Results and discussion. Literature sources related to the methods of synthesis of substituted acyl thioureas and acyl thiosemicarbazides were systematized and analyzed. The main approaches for the formation of these compounds are revealed: stepwise formation from carboxylic acids, through acyl chlorides and acyl isothiocyanates followed by nucleophilic addition of amines or hydrazides of carboxylic acids ("one-pot synthesis"), nucleophilic addition of amines or hydrazides of carboxylic acids directly to acyl isothiocyanates and parallel microwave synthesis using acyl isothiocyanates and amines as reagents. The possibility of their use as ligands for the formation of complex compounds with transition metal ions was discussed. In the review biological activity of these structures, namely antimicrobial, fungicidal, antitumor, antiviral, antifungal and other activities was detailazed.

Conclusions. The basic approaches to the synthesis of substituted acylthuoureas and acyl thiosemicarbazides which include the application of carboxylic acids, their derivatives (acyl halides and isothiocyanates) and N-nucleophiles as initial compounds were discussed. It was shown that aforementioned class of the compounds reveals the versatile biological activity and are promising for further structural modification aimed to the search of novel drugs

The aim to conduct a comparative analysis of the population's consumption of antiepileptic drugs in the retail pharmaceutical markets of developing countries, including Ukraine, Kazakhstan and Belarus in the period 2016-2020.

Materials and methods. The objects of the research were the data of marketing agencies that monitor the domestic pharmaceutical market in the countries under study. In particular, the range of AED in Ukraine was determined using the market research system «Pharmstandard» of the company «Morion». Analytical-comparative, systematic, graphical, logical, mathematical-statistical research methods were used.

Results. The results of the study show that the market of antiepileptic drugs in Ukraine, Kazakhstan and Belarus mainly depends on foreign manufacturers, in particular by 60 %, 92 % and 46 % respectively in 2020, and does not meet the needs of the population in accordance with WHO recommendations. It is established that in the market of Ukraine, Kazakhstan during 2016-2019 there is a general trend of increasing retail sales of antiepileptic drugs, which are not included in the WHO Basic List of Essential Medicines, both in natural and in monetary terms. The results of the analysis of retail sales of drugs in the Belarusian market in quantitative and monetary terms indicate an increase in sales of drugs for the treatment of epilepsy, which are included in the WHO Basic List of Essential Medicines.

Conclusions. The presence in Ukraine of a difficult situation with the consumption of antiepileptic drugs in comparison with other countries of the reference group indicates the need to implement comprehensive programs to combat the spread of epilepsy and the introduction of models for the rational use of limited health resources

The article presents clinical case of Job syndrome, variant of primary immune deficiency disease confirmed genetically. This case is interesting for its early diagnosis due to comprehensive assessment of anamnestic, clinical, and laboratory data. Such typical phenotypic features as facial dysmorphisms, recurrent localized purulent infections, and laboratory parameters (absolute neutropenia and eosinophilia) were the major signs of autosomal dominant hyper IgE syndrome in a child with normal IgE levels. The combination of 2 heterozygous mutations in STAT3 gene inherited from his father and his mother has played its role in disease clinical features in the child.
Headaches and Humility: Introducing Preservice Teachers to Undergraduate Research
Authors: Baker J.
Published: May 2022

For some teacher educators, the singular goal of teacher preparation is to license new teachers, not develop critical thinkers. This lack of thinking beyond lesson plans, course standards, and classroom management to explore high impact practices – such as undergraduate research – leads to the deterioration of the education field and limits preservice teachers’ understandings of their own curricular and pedagogical practices. This article is a poetic reflection – through headaches and humility – on how 157 preservice teachers (PTs) made connections between curricular research and practice. The article also addresses steps taken by a teacher educator to ensure their success and mechanisms to overcome preservice teachers’ (as well as other teacher educators’) perceptions that educators do not need research skills.
Trauma and Academic Impact: Stories From At-Risk Youth
Authors: Morton Brenda
Published: May 2022

Youth continue to leave school prior to earning a high school diploma, despite focused attention and resources on this population of students (Porche, et al., 2011), leaving unanswered questions as to what support this group of students need. Researchers identified attendance, disciplinary issues, and low grade point average, as prevalent in dropouts, but few have explored the story behind the statistics. This study sought to fill this gap in the literature by exploring the role of trauma and Adverse Childhood Experiences (ACEs) in the lives of students at risk for academic failure, by examining their lived experiences. To that end, this study reports the lived experiences of a group of high school students enrolled in an alternative education program in a rural, Pacific Northwest high school. The participants shared the challenges and supports that they believed influenced their academic journey. These challenges and supports were found both at home and in the classroom. Their lived experiences provide compelling rationale for the importance of trauma-informed training for school personnel. By understanding the prevalence of trauma and ACEs, and the connection to academic impact, interventions can be created to support this vulnerable group of learners (Iachini, Petiwala, DeHart, 2016).
Adjusting to Change: Learning American Sign Language Online During A Global Pandemic
Authors: Gournaris Kara
Published: May 2022

Second language acquisition of American Sign Language (ASL) requires opportunities for engagement with native language models (Krashen, 1988). The shift to online instruction due to the impact of COVID-19 presented unique challenges for ASL programs across the United States. With little time to redesign courses, instructors and students had to navigate the experience of online learning together. The students who participated in this 2020 study at Western Oregon University (WOU) shared their raw experiences related to this transition, and unfortunately, one year later, many of the same barriers reported by students persist. The purpose of this article is to share their stories, and present evidence that face-to-face instruction of ASL is essential and cannot simply be replaced with online learning without negative consequences. Access to immersion opportunities and consistent engagement with native language models are not easy to replicate in online environments, pointing to the fact that there is a need for face-to-face opportunities to acquire ASL when it is safe to do so.

Published: May 2022

Introduction. Clinical trials are the gold standard for assessing the effectiveness and safety of treatments. The objective of the current study was to assess provider opinions regarding implementing pediatric clinical trials in various practice settings across Kansas.  
Methods. The study was completed within the Sunflower Pediatric Clinical Trials Research Extension (SPeCTRE), an affiliate of the IDeA States Pediatric Clinical Trials Network (ISPCTN). A cross-sectional, 36-item survey was administered to a state-wide convenience sample targeting health care providers and clinic staff.  
Results. A total of 119 health care providers and clinic staff completed surveys; 31% were physicians. Physicians were more likely than other clinic staff to have experience with clinical trials (correlation coefficient [CC]=0.270, p=0.004). When compared to urban respondents, rural providers were less supportive of recruitment for clinical trials in their practices (CC=-0.251, p=0.008) and more likely to feel comfortable referring patients for clinical trials involving treatments that their insurance did not cover (CC=0.302, p=0.001). 
Conclusions. A range of rural and urban health care professionals support the performance of pediatric clinical trials but identify several barriers as well. These results will support future pediatric clinical trials across the country including Kansas.
Causes of Anemia in Patients Seen in a Rural Community Hematology Clinic
Authors: Featherstone Sarah , Cathcart-Rake William , Zackula Rosey , Beck Larry
Published: May 2022

Introduction. Anemia is a common medical disorder seen in consultation by hematologists. This study was performed to determine the incidence of the etiologies causing anemia in patients referred to the hematologists at Tammy Walker Cancer Center (TWCC) in the rural Kansas community of Salina. An additional goal of the study was to compare the frequencies of different etiologies for anemia in this cohort of patients with those previously reported by four academic medical centers.

Methods. A retrospective review of the medical records of 152 patients seen at TWCC between August 2015 and May 2019 was performed. The patient’s history and physical exam, complete blood count and various additional hematologic studies ordered at the discretion of the TWCC hematologist were used to determine the etiology of each patient’s anemia.

Results. The most common causes of anemia found in the chart review were iron deficiency (48.7%), hematologic malignancy (14.5%), chronic inflammation (13.8%), renal insufficiency (11.2%), and unexplained anemia (9.9%). While the incidences of anemia due to hematologic malignancy, chronic inflammation, and renal insufficiency were similar to that reported previously by four academic medical centers, significantly more iron deficiency and less unexplained anemia were found in the patients referred to TWCC.

Conclusions. The causes of anemia in patients seen at TWCC were similar to those reported by academic medical centers; however, the incidences were different. The differences in findings may reflect dissimilarities in the demographics of referral populations, the duration and extent of the evaluation at TWCC, or referral patterns.

A classifier for violations detected during internal audits as state-funded higher education institutions
Authors: Spiridonova Natalia E.
Published: May 2022

Subject. A classifier of violations is a tool used to standardise and improve audit activities and, thus, increase their efficiency. It allows structuring possible violations, connecting them with risks related to the activities of state-funded institutions, and providing a uniform approach to the systematisation of violations. Since internal audits in state-funded institutions are characterised by a lack of regulations and an absence of standard methods, there is a need to study issues related to their practical implementation. This proves the importance of the problem studied in the article. Objectives. Developing a structure for the classifier of violations detected during internal audits at state-funded higher education institutions. Methodology. The following methods were used to achieve the goals: analysis, grouping, comparison, and generalisation. Results. The article proposes a structure for the classifier of violations detected during internal audits at state-funded higher education institutions. It establishes how the developed structure for the classifier of violations can be adapted to the activities of state (municipal) institutions of various types and spheres of activity. It determines the main characteristics which help record violations and signs indicating a high probability of their detection. Results and discussion. A critical analysis of the results of the study was used to identify its main advantages and disadvantages. The ways of minimising the impact of the identified disadvantages were proposed. Conclusions. The results of the study can be used by both scholars and practising specialists to develop and update classifiers for violations at state (municipal) institutions.
Term structure of risk factor premiums: evidence from international equity markets
Authors: Korotkikh Viacheslav V.
Published: May 2022

Subject. Factor models are among the most popular tools for the analysis of stock market risks. For a long time, factor models were developed mainly by the formation of additional risk factors. However, static linear specifications are usually not sufficiently sensitive to structural changes in the market and to changes in the operational regimes of markets and in this regard they have a limited number of functions. The idea of regime switching is natural for markets and is intuitively comprehensible, therefore, in order to take into account the non-linear dependencies in factor models of risk analysis, it is advisable to use the mechanism of Markov regime switching with them. Objectives. Statistical analysis of the dynamic properties of the factor structure of risk premiums for transactions with stock market financial instruments based on a modification of the Fama & MacBeth procedure that takes into account the current market regime. Methods: In our study, we used parametric methods of data analysis and machine learning methods, description, analysis, synthesis, induction, deduction, comparison, and grouping method. An EM algorithm was used for the parametric identification of models with Markov regime switching. Results: The paper provides convincing evidence that the relationship between the excess return of financial instruments and factor loads is influenced by the current regime in the market. The main feature of the low volatility regime is the presence of a positive statistically significant risk-adjusted premium. The change in the current regime in the market is accompanied by the transformation of the factor structure of the risk premium. This fact indicates that it is reasonable to divide risk factors into speculative and protective risk factors. Speculative factors include market risks, the risk related to the size of the issuing company, and the momentum effect risk. They have a positive and significant premium in the low volatility regime. The protective factors include risk factors related to value, capital investment, and return on equity. The protective factors are characterised by a positive and significant premium only during periods of high volatility.

Gynecomastia is a reviewed condition portrayed by the development of the male bosom that influences a critical extent of the male populace. Plenty of fluctuating careful methodologies at present exists in the writing; consequently, this complete audit tried to break down careful practice examples and patterns as they relate to gynecomastia grade and seriousness. The ongoing writing was questioned using the PubMed and MEDLINE data sets — given predefined boundaries and individual audits, 17 investigations were eventually included. Key information focuses included gynecomastia grade, careful intercession, the pace of confusion, including hematoma, seroma, disease, corruption, and channel use. Two-example t-test was used for additional investigation. A sum of 1112 patients went through careful treatment for gynecomastia. Skin-saving mastectomy regardless of liposuction was the most often utilized technique followed by mastectomy with skin decrease. Significant complexity rates went from 0% to 33%, with hematoma development being generally normal (5.8%) followed by seroma (2.4%). There was a higher pace of hematoma/seroma arrangement among creators who regularly used channel situation (9.78% versus 8.36%; P = 0.0051); nonetheless, this is logically inferable from the enormous error in the level of grade III patients found in each gathering (50.23% versus 4.36%; P = 0.0000). As a wide assortment of careful procedures exists for the treatment of gynecomastia, an individualized methodology given gynecomastia grade and patient inclination might help the specialist in giving ideal results. This senior creator's favoured technique for the treatment of gynecomastia is shown in the included calculation.

The Role of Target Representation in Subsequent Search Misses Effect
Authors: Ermolova A.M. , Gorbunova E.S.
Published: May 2022

Subsequent search misses (SSM) effect is the decrease in accuracy of the second target detection after finding the first target in visual search task. Two main explanations of this phenomenon (resource depletion and «perceptual bias» accounts) refer to functioning of attention. In this experiment, the dependence of effect’s magnitude from the degree of target’s representation accuracy was studied. The degree of representation accuracy detail may be varied by target template: we used the verbal title of the target category, the morphed averaged image of an object from a category, or both title and image (target templates are provided in ascending order of representation detail). Participants’ task was to search for the targets among distracters. Targets could be identical or perceptually different. 60 participants (12 male, 48 female) aged from 18 to 35 (M = 21.33, SD = 3.61) participated in the study. SSM magnitude was shown to depend on the type of target. The results are discussed in the context of combined (mixed) theory of the SSM.

The article aims to present the results of the study of intercultural competence as a predictor of effective intercultural interaction. The mechanism by which this effect is achieved is currently poorly understood. The study involved students from Russian universities (N=748) aged 18 to 25 years (M=20.09, SD= 1.73). 85% of the sample were women. The following methods were used: “Integrative questionnaire of intercultural competence”, the Scale of intergroup anxiety U.The scales of Attributive confidence and perceived predictability and Self-assessment of the effectiveness of cross-cultural communication was from the studies of W. Gudykanst, Scale of evaluation of the desire to interact with a partner of other cultures. All scales were modified for the study and showed good reliability. The theoretical model was tested using path analysis. The effects of all components of the integrative model of intercultural competence on the desire to interact with a partner in intercultural communication and self-assessment of its effectiveness were found, except for the “lack of ethnocentrism”sub-scale. It is also shown that the effects of cross-cultural interest and cross-cultural stability on the perceived effectiveness of communication with a foreign cultural partner and the desire to interact with them are mediated by intergroup anxiety and perceived predictability of cross-cultural communication.
Possibilities of Dispositional and Situational Variants of Coping Strategies Assessment (on the Model of General and Pandemic-Specific Versions of COPE)
Authors: Rasskazova E.I.
Published: May 2022

The problem of stability / variability of ways of coping with stress and of the need of diagnostic of situational coping is actual for both psychology of stress and self-regulation psychology. The pandemic situation presents a model of the overall stressful situation that allows such a comparison. The aim is to reveal methodological differences in assessing general and specific (for a pandemic situation) coping strategies and their relationship with the reaction to a pandemic and subjective well-being, and their dynamics over 3—4 weeks of the self-isolation regime. 402 adults filled the general and situational (for a pandemic) versions of COPE, Satisfaction With Life Scale, Scale of Positive And Negative Experiences, measures for anxiety and adherence to self-isolation recommendation. After 3—4 weeks, 203 respondents re-completed the well-being and pandemic reaction scales. The results demonstrate that in a pandemic situation, people are more likely to report using behavioral disengagement, restraint and acceptance, and less often to report all other strategies than in general. Situational use of emotional support and emotions venting improve the prediction of anxiety of the negative consequences of a pandemic and anxiety of infection. Denial and non-acceptance of the pandemic predict low adherence with recommendations. An increase in infection anxiety in 3—4 weeks is more pronounced in those using emotional support and substances, while decrease in anxiety of negative consequences — in those with lower use of emotional support and lower behavioral disengagement in pandemic.
Dynamic Scheduler for WSN Applications in Precision Agriculture
Authors: Amit Kumar Bindal Kunal Goel,
Published: May 2022

Sensors may be configured to collect the various parameters those do not change over a long interval (i.e. water level, soil attributes/ fertilizer quantity of agriculture land/ growth of crops). In case, if all sensors start transmission after a lengthy intermission, it may cause packet drop over network and excessive resources may be exhausted due to retransmission. To manage the bulk data forwarding with minimum resource consumption, in this paper, an application scheduler is introduced to enforce the discipline bulk data transmission. Its performance is analyzed using LEACH protocol under the constraints of various parameters (Throughput/remaining energy/number of dead/alive sensors) with sensor density (100-300).
Investigation of Water Pollution in the River with Second-Order Explicit Finite Difference Scheme of Advection-Diffusion Equation and First-Order Explicit Finite Difference Scheme of Advection-Diffusion Equation

Published: May 2022

The perseverance of this research article is to investigate water pollution in rivers with a second-order explicit finite difference scheme of advection-diffusion equation (ADE) and a first-order explicit finite difference scheme of ADE. For investigation, two numerical schemes exploit here FTCSCS and second-order Lax-Wendroff type of ADE which is our new proposed one. In earlier Lax-Wendroff, type scheme existed only for hyperbolic partial differential equation (PDE), here a new second-order Lax-Wendroff type scheme is proposed for parabolic PDE and in addition assist to investigate water pollution with an expectation of better yield compared to the existing one. We implement numerical schemes to estimate the pollutant in water at different times and different points of water bodies. We investigate the numerical behaviour of water pollution by implementing the explicit centred difference scheme (FTCSCS) for advection-diffusion and for our proposed second-order Lax-Wendroff type scheme. Our computational result verifies the qualitative behavior of the solution of ADE for various considerations of the parameters.
A Survey: Detection and Mitigation Techniques of Sybil in the Networks
Authors: Dr Shaveta Rani, Dr Paramjeet Singh Meena Bharti,
Published: May 2022

Wireless networks are complicated to put together, and the more people use them over time, the more complicated they become. Wireless networks are made up of many different types of technology, which means they have vulnerabilities. One vulnerability is that they are easily spoofed or impersonated by Sybil attacks. In a Sybil attack, the attacker disguises themselves as someone else and generates various identities to have access to the system. This type of attack is typically accomplished by creating multiple fake user accounts. The attacker then uses these fake accounts to promote their content or ideas, vote for their own content or ideas, and/or harass other users. Since wireless networks are very resource-constrained, it is vital to develop more efficient and lightweight trustworthy security mechanisms to identify & track Sybil attacks as these are a major concern for the stability or security of the network. There are some security schemes for prevention against Sybil attacks, like cryptography, privacy-preserving solutions and lightweight authentication. Cryptography and privacy-preserving techniques require key management and additional infrastructure overhead, which makes them difficult to establish and maintain in a limited resource environment. The lightweight trusted system detects & avoids single node and multi-node attacks under different conditions. In this paper, a survey is conducted on various techniques for the detection of Sybil attacks.
