Published: January 2023

The Picaresque tradition is a mode of writing that began in Spain in the 16th century and flourished in the 17th and 18th centuries throughout the rest of Europe. It is a literary tradition that has continued to influence modern fiction writing to date. The current paper examined the picaresque and popular African literature narrative techniques through conducting an in-depth analysis of the following texts; Kill Me Quick, Mission to Kala, The Angels Die, and A Sport of Nature. To effectively address the task, the study examined narratives and narrative techniques in the prose fiction under study. The paper then deployed the Structural Literary Theory in an effort to decode the intertextuality between the texts. The study established that the texts under study are interconnected through the main characters, especially the picaro/picara. An examination of Gustav Freytag’s narrative structure was conducted and similarities and differences in the narrative structures of the texts under study was observed. The Postcolonial Literary Theory was also consulted where specific strands of the theory as propounded by Vorn Gorp, and Frantz Fanon were blended to furnish the study with the necessary theoretical backbone to exhaustively study picaresque narratives in popular literature. In conclusion, the study established that the Picaresque and Popular Literature writing modes are interconnected through the use plot and main characters. The study also established that the non-linear and episodic plot structures are the most commonly used techniques in picaresque and popular writing modes.

Authors: LEPEYKO T. , JIANPING M.
Published: January 2023

The problem of personnel management of a multinational company, where the personnel represents a specific national culture, but for the efficient performance of the organization, must fully accept its organizational culture, is relevant for business now. This is what provokes a conflict between the values of the personnel’s national culture, which are always shared by the carriers of this culture and the expected personnel’s behavior, which is a manifestation of the organizational culture. The purpose of the study is to conduct an analysis of the values of the personnel’s organizational and national culture in a Chinese multinational organization (School of Economics and Management of Neijiang Pedagogical University) based on a value approach to determine a possible conflict between the national and organizational culture of the personnel in this organization and to develop practical recommendations for eliminating this conflict to increase the personnel effectiveness in a multinational organization in the context of Chinese culture. The scientific methods that were used are methodological approaches developed by M. Rokeach, S. Schwartz and G. Hofstede for the study of personnel’s organizational and national culture in an organization based on the value approach. The main results of the analysis of the personnel’s organizational and national culture in this Chinese multinational organization indicate a significant influence of the personnel’s Chinese national culture (for the personnel being the carrier of this culture) on the personnel’s organizational culture in this organization and the presence of a conflict between the personnel’s organizational and national culture. The practical significance of the obtained results is that the proposed recommendations for adjusting the structure of personnel’s values will allow the management of the company to eliminate the conflict between the personnel’s national and organizational culture and increase the efficiency of this personnel

Published: January 2023

The relevance of the research topic lies in revealing of the trend of accounting in the context of Ukraine’s European integration aspirations through the study of theoretical issues and experience of Ukraine. The reforming of accounting has already been launched in Ukraine, but this path is quite difficult and slow; however, it is of great importance in the formation of the economic significance of Ukraine and its adaptation to international requirements. In recent years, reform has become even more important, as the country’s European integration aspirations determine the rapid development of all economic sectors. Today’s challenges, such as the aftermath of the COVID-19 pandemic and military action in Ukraine, are modifying business conditions and making it urgent to propose ways to reform and address trends in accounting in Ukraine. The purpose of the study is to reveal the trend of accounting in the context of Ukraine’s European integration aspirations through the disclosure of theoretical issues and experience. The analysis of the problem proved that a large number of problems associated with the development of accounting existed, and there was an urgent need for its detailed study and solution. The results of the study highlighted the features of accounting in the European integration environment and the characteristics of the stages of development of accounting. The practical significance of the research results is the possibility to apply them on the Ukrainian enterprises in order to improve the skills of accountants in theoretical knowledge and possible application in the discipline of “Accounting” in universities

Published: January 2023

The globalization of economic relations and the integration of Ukraine into the world financial market have significant impact on decision-making in an insurance company in Ukraine. These aspects actualize the study of the insurance companies’ activities in the conditions of world financial market cyclical development, and it determines the purpose of the article. The purpose of the study is to develop theoretical and methodological provisions and practical recommendations for managing reinsurance in conditions of cyclical development of the global financial market. Solving the tasks set in the research was carried out using scientific methods of analysis, synthesis, induction, deduction, and analogy – to study trends in the development of the Ukrainian insurance market; logical generalization – to determine the peculiarities of reinsurance management in conditions of cyclicity of global financial markets; comparative and statistical analysis – for analyzing the share of premiums belonging to non-resident reinsurers; Fourier analysis – for analyzing the cyclicity of the development of the global financial market and the reinsurance market in Ukraine. Global business activity develops cyclically. The first cycle is long-term and consists of 14 quarters. Within the long-term cycle, harmonics of a shorter cycle, namely 1 year, were detected. The reinsurance market in Ukraine also develops cyclically. The length of the cycle is 4 quarters. It was established that the peaks of the harmonic oscillations of the development cycle of domestic reinsurance and the world cycle of business activity are antiphase, that is, the phase of the oscillations differs by half a period. The length of the domestic reinsurance development cycle and the global business activity cycle are equal, and the distance between the extremes of the cycle functions is 2 quarters. The practical value of the obtained results is that the established relationships between the cycles and phases of the global business activity development and the reinsurance market of Ukraine provide a toolkit for making management decisions regarding the modeling of a reinsurance portfolio effective structure in the insurance company
A NONLINEAR MATHEMATICAL MODEL OF DYNAMICS OF PRODUCTION AND ECONOMIC OBJECTS

Published: January 2023

A person who makes decisions regarding the management of an industrial and economic object feels the need for tools to solve numerous problems that arise in the process of functioning of this object as an economic system in the conditions of interaction with the environment. The purpose of this work is to build an analytical model of the production and economic system, which would allow studying the structural changes that may occur in the process of functioning of economic objects with a closed cycle of production activity and which determine the possible ways of evolution of an open economic system over time (phase trajectories of evolution). The methodology of nonlinear dynamics and economic synergy was used to create the model. The work proposes a mathematical model of the production and economic system with a small number of phase variables that have a market interpretation, and determines endogenous and exogenous parameters that characterize the state of the system and the direction of its development. The model contains a system of two ordinary differential equations with quadratic nonlinearity. This formalization made it possible to obtain general information about the development trajectories of this system and its stationary states with the identification of the most significant critical modes of functioning. Qualitative analysis based on this model showed that non-linearity leads to non-unity of equilibrium states and the existence of both stable and unstable development trajectories of the economic system under study. This model can be used to manage any complete economic unit in which an independent closed cycle of reproduction is ensured

Background: Celiac disease (CD) is an autoimmune disease triggered by a permanent sensitivity to gluten, causing a significant disturbance to the small intestines and multiple other organs. We aim in this study to assess physicians’ knowledge, practice and attitude towards celiac disease screening. Assessing the physicians’ knowledge will help us to understand how we can improve the practice regarding celiac disease. Methodology: A cross-sectional study using a validated questionnaire from previous studies distributed electronically among primary care and pediatric physicians. The questionnaire consisted of: 7 questions about physicians characteristics, 15 questions about knowledge, 15 questions about attitude and 5 practice questions. Respondents were asked to identify any queries they had about the questions. Time needed to fill the questionnaire was approximately 10 minutes. Results: The final sample was 264 participants with mean age of 32.31 years old where 79.9 % of the participants were aged under 40 years old. Moreover, 52.3 % of the participants were females. Considering specialty, we found that 48.5 % of the participants were family medicine physicians while 47.0 % were general pediatrics. Chronic/ intermittent diarrhea and weight loss were the most commonly known symptoms among the participants (85.1 % and 85.6 % respectively) followed by abdominal pain (78.1 %). Considering the best first line screening tool of celiac disease, 78.1 % of the participants successfully identified Anti-tissue transglutaminase antibody and 85.6 % of them were able to identify bowel biopsy as the best tool in order to confirm the diagnosis of CD, however only 20.9 % correctly identified Anti-endomysium antibody as the best tool for follow-up. Conclusion: We found that there is a deficiency in knowledge about CD among physicians with no significant difference between pediatrics and family medicine physicians. The physicians had moderate knowledge considering symptoms and risk factors of CD with good knowledge considering the diagnosis tool. More educating courses should be provided to the physicians about the diagnosis and management of CD. Key words: awareness, Celiac disease, pediatric age group, Saudi Arabia

Published: January 2023

Introduction: Celiac disease (CD) is an autoimmune disease of the small intestine in which ingestion of gluten leads to destruction of intestinal areas in affected patients. Lifelong adherence to a gluten-free diet (GFD) is the only possible treatment for CD. It is less evident in adults considering the nutrient status in patients on GFD. Therefore, the aim of the study is to systematically evaluate the effect of GFD on the nutritional status of celiac patients. Methodology: A comprehensive electronic search with time and language restrictions was done. Several known databases were included: “Google Scholar, PubMed, The Cochrane Library, Web of Science” from 2000 to 2022. Keywords used included “celiac disease”, “nutrient status”, “gluten-free diet”, “nutritional deficiencies”, “dietary deficiencies”, “nutrient intake”, “micronutrient”, “macronutrient”, “vitamin”, “mineral”, “fiber intake”, “Protein intake”, and “Fat intake” Results: The electronic search strategy conducted in this review ended in 875 hits which after removing duplications reduced to 360 studies. These 360 studies were considered eligible for further evaluation, from which 346 studies were excluded for different reasons as 216 studies were based on title and abstract, 86 studies were not relevant to the subject of this study or of this review, 17 were considered replies of authors, 2 were books, and 27 were reviews. Finally , 12 articles were included in the qualitative synthesis of the present review. Conclusion: The current review showed that gluten free diet is associated with unbalanced intake of macro and micronutrients in both, celiac women and men mainly because of the unhealthy dietary habits and difficulty eliminating gluten from the diet which leads to low cereal intake and high consumption of processed gluten free products.

Background: Chronic rhinosinusitis is one of the most prevalent chronic diseases worldwide, affecting all age groups. It is a condition leading to a significant decrease in the quality of life of patients, and requires a specific treatment approach. This study aims to assess the prevalence, quality of life and risk factors of chronic rhinosinusitis in order to develop and promote public health, wellbeing and awareness. Methodology: This is a cross-sectional study which was conducted in the Kingdom of Saudi Arabia, from August to October 2021. We collected the data using a validated, self-administrated online sinonasal outcome test (SNOT-22) questionnaire in Arabic. The questionnaire was distributed through social media and aimed to assess the prevalence and risk factors of chronic rhinosinusitis in the Kingdom of Saudi Arabia in 2021. Results: In the current study, we collected data from 4963 individuals in Saudi Arabia who responded to to our questionnaire. Participants had a mean age of 31.99 (SD=11.59) years old, 62.0% were females and 92.9% were Saudis. Among the total sample, the prevalence of chronic rhinosinusitis (CRS) was 22.5%. The prevalence of CRS was significantly lower in patients aged between 18-29 years old (19.4%) compared with the 30-49 age group (27.1%) and 50-69 age group (23.2%) (P=0.000). Moreover, we found that the prevalence of CRS was significantly higher among females (24.0% vs 20.2%, P=0.002) and among Saudis compared to non-Saudis (22.9% vs 17.6%, P=0.022). Furthermore, there was a significant reduction in the quality of life among patients with CRS where the mean score of SNOT-22 was 44.04 (SD=25.38) compared with 26.82 (SD=26.35) in non-patients. Conclusion: The current study revealed a high prevalence of CRS among individuals in Saudi Arabia especially among older females, those with chronic conditions and those who had been exposed to different risk factors such as smoking. Moreover, CRS was found to have a significantly negative impact on the quality of life for those participants diagnosed with the condition.

Background: There is lack of research which identifies and analyses the quality of life among patients with primary open angle glaucoma by using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) and the World Health Organization Quality of Life abbreviated version questionnaire (WHOQOL-BREF) tool. Therefore, the aim of the current study was to assess the quality of life among patients in Riyadh, Saudi Arabia with primary open angle glaucoma using these tools. Methodology: This was a cross sectional study conducted among patients with primary open angle glaucoma who lived in Riyadh, Saudi Arabia. Data was collected via an online questionnaire and through contact with the patients in Arabic. The questionnaire included two main tools to assess the quality of life among patients with open angle glaucoma including the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) and the World Health Organization Quality of Life abbreviated version questionnaire (WHOQOL-BREF) tool. Results: In the current study, we collected 392 responses to our questionnaire from patients who were diagnosed with open angle glaucoma. The mean score of the NEI VFQ-25 was 69.68 (SD=21.08) where the highest scores were reported in colour vision (76.47 (SD=27.28)), followed by social functioning (74.32 (SD=25.21)), general vision (73.55 (SD=16.72)), general health (71.4 (SD=18.64), and distance activities (71.46 (SD=23.53)). The poorest quality of life because of open angle glaucoma was reported considering role difficulties (65.53 (SD=27.58)), ocular pain (66.01 (SD=23.54)) andmental health (66.06 (SD=23.84)).

The assembly of profound global developmental and intellectual delay, short stature and severe growth restriction, certain characteristic dysmorphic facial features, with the occasional inclusion of behavioral abnormalities, sensory disturbances, as well as some vague bony involvement that can be rather inconsistent, all constitute an extraordinarily uncommon clinical entity coined as “Alazami Syndrome”, the diagnosis of which can be further established by genetic studies confirming the autosomal recessive biallelic frameshift mutations in the LARP7 gene, culminating in a complex and novel form of primordial dwarfism (PD). Herein, we report a patient presenting with this disease, comorbid with pathogenetic variants in SEPSECS mRNA as well, which cause an amalgamation of central nervous system anomalies that include microcephaly, atrophy, mental retardation, and epilepsy, termed as “Pontocerebellar hypoplasia”, accentuating the rarity of our case, as no such variants of these ailments have been formerly defined in preexisting literature. Genetic sequencing of our patient provides further affirmation of the culpability of the pathogenetic variants for each respective condition, and which suggests a potential connection between Alazami syndrome and other genetic malformation disorders.

The largest proportion of patients were house wives or unemployed (41.3%). More than half of the participants were school –educated (59.7%), while 18.7% were university educated. Almost half of participants (46.6%) reported disease duration between 6-9 years, while for that of 29.2% it was 2-5 years, and for 24.3% was 10 years or more. HbA1c was <7% in 46% of participants. Only 18.3% of participants were awareof DPN. Two-thirds of participants had poor knowledge level about DPN. The most frequently experienced neuropathic symptoms were feeling weak all over most of the time (62.7%), having an open foot sore (59.7%), having muscle lower limb cramps (48.7%) and experiencing burning lower limb pain (45.7%). Prevalence of DPN according to the history part of the MNSI was 9.3% of type 2 diabetic patients had DPN. Participants’ knowledge levels were significantly higher among those with DPN (p=0.045). However, their knowledge levels did not differ significantly according to their personal or clinical characteristics. Conclusions: Most type 2 diabetic patients in Abha City have poor knowledge about DPN and its risk factors. However, prevalence of DPN among them is relatively low.

Published: January 2023

This article introduces EERCASE, a Computer Aided Software Engineering tool that is based on the best practices of the Model Driven Development paradigm to provide a consistent environment for relational database design. EERCASE follows the graphical notation of the Enhanced Entity–Relationship model according to Elmasri and Navathe, implements the EERMM metamodel to avoid syntactically invalid constructs, shows and describes static semantic errors, and generates data definition code that takes into account advanced structural validations. The theoretical and technical framework used for the implementation of EERCASE is discussed, with emphasis on the restrictive and informative validations performed by it. In addition, considering feedbacks on modeling errors and code generation, EERCASE is also presented as a computational environment that favors active learning.

Published: January 2023

The gut microbiota of insects is one of the unexplored areas. The association with these microbiomes plays a vital role in supporting their survival and combat with ecological challenges. Mosquito is one of the focal attention insects among the Arthopods, being the vector of many pathogenic diseases including dengue and malaria. A variety of strategies have been designed and implemented to fight against these vectors including obnoxious use of insecticides. Indiscriminate use of insecticides has led to development of resistance against broad range of insecticides. Crucial role of bacteria in insecticide resistance has been under discussion. Many studies focus on the insecticide resistance due to gut microbiome. Thus, the role of gut microbiome is an important area for designing new vector control strategies and their role in improvement of a healthy environment.

Titanium Extraction Metallurgy Developments and Control of Impurity Elements
Authors: R.V.S. Nagesh Chaganti
Published: January 2023

Titanium extraction metallurgy poses numerous challenges owing to a combination of various characteristics such as high chemical reactivity, high melting point, strong affinity towards oxygen and nitrogen, pyrophoricity of nascent sponge. Kroll process of magnesium reduction of has become the widely employed titanium sponge production technology. Sodium reduction of TiCl4 known as Hunter’s process has also been employed for the industrial production of titanium sponges for about two decades. Subsequently quoting techno-economic reasons, the Hunter sponge plants across the world have been closed. There have been several efforts over the years to evolve an alternative to the Kroll process mainly to achieve a simple and cost and energy-effective titanium extraction process. Control of impurity elements in the titanium metal during the metal extraction process assumes greater importance as thermodynamics does not favour any purification method to be employed for the metal. This chapter brings out historical developments in titanium extraction metallurgy and highlights recent developments as well to produce high-purity titanium sponges required for titanium alloys for the end applications across various sectors.

Authors: Dudhamal Tukaram
Published: January 2023

In Ayurveda, treatment with intentional therapeutic heat burns is called Agnikarma (thermal cauterization), which is one of the para-surgical procedures. It is also called Dahan Karma (thermal cauterization). Various painful conditions like joint pain, sciatica, tendinopathies, headache, abdominal cramps/discomfort, and few convulsive disorders like epilepsy, schizophrenia, psycho-somatic disorders, and some skin diseases can be treated with this intentional heat burn therapy. Agnikarma has widely been used in clinical practice since time immemorial and is said to have immediate and long-lasting relief, as mentioned in the Indian traditional therapy. This para-surgical procedure is practiced in all teaching institutes of Ayurveda in India, and many researchers are publishing the research work done on Agnikarma in musculo-skeletal disorders. In this chapter, the concept of Agnikarma along with a brief procedure and published evidence-based research studies on osteoarthritis (OA) of the knee joint treated with Agnikarma are critically analyzed. This chapter contributes the knowledge of the Indian traditional para-surgical procedure in musculoskeletal disorders in general and OA knee joint in particular.

Published: January 2023

Dusty plasma offers an extensive study of space and astrophysical environments. In this chapter, we have studied some of the basic properties of dusty plasmas, interaction of dust and plasma particles, and the effect of intramolecular attraction and repulsion between these plasma and dust grain particles. During these investigations, we have discussed a few basic relations of dusty plasma and the effect of dust particles on the nonlinear wave structures in dusty plasma. Here, we have also studied the various aspects of dust-acoustic solitary waves (DASWs) in inhomogeneous plasma. To study and analyze the various aspects of DAWs in inhomogeneous plasmas, the governing fluid equations of plasmas are considered to derive the Korteweg de-Vries (KdV) equation. The solution of the KdV equation is obtained as soliton or solitary wave. The solitary wave solution indicates the various characteristics of DASWs in the inhomogeneous dusty plasma. In this chapter, a systematic and extensive study on DAWs is also included for the inhomogeneous and unmagnetized plasmas.
High-Temperature Effects on Supersonic Flow around a Wedge
Authors: Volkov Konstantin
Published: January 2023

The development of the flow pattern that arises during the interaction of a shock wave with a wedge is discussed. Mathematical modeling of the flow around the wedge is carried out with Euler equations. These equations describe the unsteady flow of an inviscid compressible fluid around a wedge in a two-dimensional domain. To take into account high-temperature effects on super- and hypersonic flows, the model developed takes into account equilibrium chemical reactions in the air, ionization, and dissociation processes. The initial parameters of the flow are set equal to the parameters of the flow behind the shock wave in accordance with the Rankine–Hugoniot relations. The solutions to the problem obtained with the model of ideal perfect gas and the model taking into account high-temperature effects in the air are compared. The influence of high-temperature effects on the distribution of flow quantities is discussed.
