Yoga: Maintaining Healthy Employees at Workplace
Authors:   Associate professor, Doon Group of Institutions, Rishikesh., Bhakuni Dr. Seema
Published: April 2022

The origin of yoga dates back to the Vedic era, when the Indian saints stressed the importance of meditation among their disciples to concentrate on studies. They started practising ‘yoga’ and it started to spread in other countries due its spiritual and physical importance. The ‘Rigveda’ though, stresses on the importance of yoga and despite the fact that it is valued by many people till now, it started gaining momentum after the declaration of the International Yoga Day on 21st June 2015. Considering its importance, first yoga university was opened in 2013 in Gujrat. Many schools introduced a yoga teacher and a period for yoga practice in the schools. The corporate or the service sector where the employees have to bear the long working hours without the opportunity to move in different directions, have no strict law related to practice of yoga. Generally, the employees either sit or work in the same posture with only a break for taking lunch. Yoga is widely practiced on 21st June but there is no provision for its practice on the other days. If yoga is introduced in the workplace as a norm, it will help the employees in remaining fit; mentally and physically both, which will result in maximum productivity from their end and the same will ultimately affect the organisation positively. The need of the hour is to understand the importance of yoga in the workplace to maintain a healthy workforce to get the desired outcome.

This article presents a description of the developed information and analytical decision support system for choosing the optimal production scenario for an agricultural enterprise IAS PPR Kazagro Choice. The problem of making managerial decisions on scenarios for the production of agricultural enterprises in Northern Kazakhstan is due to the presence of many criteria (parameters) of production and market conditions. The correctness of the consideration of the criteria predetermines the quality of management decision-making according to the preferred scenario for the functioning of an agricultural facility. The IAS PPR Kazagro Choice contains the concept of finding the best (optimal) production scenario among all possible alternative scenarios. The development of IAS PPR Kazagro Choice is based on the author’s mathematical model with a dominant hierarchy of the problem of choosing a production scenario and on the implementation of the hierarchy analysis method. IAS PPR Kazagro Choice makes it possible for a decision-maker to choose a preferred (optimal) scenario for the production of an agricultural enterprise in conditions of multifactorial influence and the availability of expert information. Distinctive characteristics of IAS PPR Kazagro Choice: focus on solving poorly structured problems; combination of traditional methods of access and processing of computer data with the capabilities of mathematical modeling. The specific applied value of the work lies in the possibility of using an adaptive implementation model for making managerial decisions on the choice of the preferred production scenario for a wide range of agricultural enterprises.

The problems of formulating and solving the problem of making decisions on the control of the hydrotreating process in a fuzzy environment are investigated and an effective method for solving such problems with the involvement of experts, their experience, knowledge and intuition is proposed. The statement of the problem of controlling the hydrotreating process, which takes place in the hydrotreating reactor and is characterized by the indistinctness of the initial information, is obtained in the form of the problem of making decisions on the choice of the optimal operating mode of the hydrotreating reactor. The management criteria were chosen to maximize the volume of production, i.e. hydrogenate, and improving the quality characteristics of the manufactured products. In the mathematical formulation of the decision-making problem for the management of the hydrotreating process in a fuzzy environment and the development of a method for its solution, the ideas of the principle of the main criterion and maximin were used by adapting them to work in a fuzzy environment. A heuristic method has been developed for solving the assigned decision-making tasks for controlling the hydrotreating process in a fuzzy environment. The originality and novelty of the applied approach to the formulation and solution of the decision-making problem in a fuzzy environment consists in increasing the adequacy of the decision made in a fuzzy environment due to the maximum use of the initial fuzzy information.

In this work, work has been carried out to systematize and analyze the main criteria that S-boxes must satisfy in order to ensure a high level of cryptographic strength of symmetric cryptographic algorithms. The set of all possible criteria for their assessment can be divided into unconditional and conditional. The unconditional criteria are those that must be met by S-boxes in order to ensure their resistance to major cryptanalytic attacks. Conditional refers to additional criteria that S-boxes must meet in order to compare S-boxes that meet the unconditional criteria. The paper presents a reasonable choice of a set of unconditional criteria that determine the optimality of S-boxes.
Stabilized finite element method for the saturation equation in the two-phase nonequilibrium fluid flow problem
Authors:   Amanzholov University, Ust-Kamenogorsk, Kazakhstan, Omariyeva D. A.
Published: April 2022

In this paper, an approximate method for solving the saturation equation in the problem of twophase nonequilibrium flow in porous media is constructed. This problem is being studied as part of the work carried out under a grant project funded by the Ministry of Education and Science of the Republic of Kazakhstan, Grant No. AP08053189. This equation refers to an equation of the convection-diffusion type with a predominance of convection and with an additional term containing the third-order derivative of the solution. Due to the hyperbolic nature of the equation, its solution is accompanied by a number of difficulties that lead to the need for a careful choice of the solution method. One of the difficulties is the appearance of non-physical oscillations at the interface of the two phases. Three classical stabilized finite element methods (SUPG, GLS and USFEM) are compared based on computational experiments. In addition, comparative calculations were performed using several stabilization parameters due to the sensitivity of the stabilized methods to the choice of these parameters and the significant dependence of stability and accuracy on them. Methodological calculations are carried out and the results of calculations with different values of mesh configurations, stabilization parameters are presented.

Published: April 2022

Emotion control in stressful situations is an important aspect of mental health. On the other hand, acute stress, affects the prefrontal cortex control, probably resulting in a loss of emotion regulation abilities. To lessen the threat, the stress response activates a number of defensive systems, including hormone messenger communication. In this article we are going to examine the present literature in relation to emotion control via understanding the function of the primary stress hormone, cortisol, and that of the catecholamines, epinephrine and norepinephrine. We have also presented and underlined the role of ICTs, web and mobile applications, AI & STEM tools, serious games, e-learning, tele-education services, etc., in the support and improvement procedures for achieving emotional self-control and regulation of the stress hormones.

Background: Heart failure with reduced ejection fraction is responsible for half of heart failure cases worldwide and implicates in substantial morbidity and mortality. However, even with clinical history and physical examination associated with conventional complementary exams, many patients remain without etiological diagnosis. Cardiac magnetic resonance has offered the possibility to clarify a variable proportion of these cases. Objective: To verify how much cardiac magnetic resonance contributes to etiologic diagnosis of heart failure with left ventricular ejection fraction <50% in a specialized service. Methods: We included individuals referred to cardiac magnetic resonance with heart failure and left ventricular ejection fraction <50% by transthoracic echocardiogram, without defined etiology, from January, 2017 to June, 2018 in a tertiary hospital. Results: The sample consisted of 87 patients, with average age of 45±16 years, 49% male and left ventricular ejection fraction 32%±13. Of the patients, 55,3% had etiological diagnosis through cardiac magnetic resonance: 33,4% myocarditis, 11.5% non-compaction cardiomyopathy, 6.8% Chagas disease, and for hypertensive heart disease, amyloidosis and arrhythmogenic right ventricle dysplasia, 1,2% each. Late gadolinium enhancement was positive in 61% and non-ischemic pattern predominated (50,5%). Reverse remodeling occurred with normalization of ventricular function in 13% of patients. Conclusion: The performance of cardiac magnetic resonance in patients without etiologic diagnosis of HF with left ventricle dysfunction is clinically significant, since it contributed more than 50% of the time to the etiology and prognosis of patients. This positive impact occurred in a tertiary cardiology teaching service, so it is possible that in other circumstances the role of the cardiac magnetic resonance may be even greater than that here presented.

An 18-year-old patient developed a direct carotid fistula after a mild craniocerebral trauma. The patient presented with tinnitus and exophthalmia, both pulsatile and on the left. A carotid Doppler study revealed high blood flow velocities and reduced resistance rates in the left internal and common carotid arteries compatible with a direct carotid fistula. Computed tomography angiography of the brain confirmed the carotid fistula. The patient was successfully referred for endovascular embolization treatment. This case demonstrates that carotid Doppler may play an important role in the diagnosis of direct carotid fistulae and the follow-up of patients undergoing endovascular therapy.

Published: April 2022

Background: Elevation of left ventricular filling pressures secondary to diastolic dysfunction plays a central role in the pathophysiology of heart failure. However, international guidelines still fail to diagnose diastolic dysfunction in some cases. Objective: To evaluate left atrial reservoir function in indeterminate diastolic function Method: Observational study with individuals in sinus rhythm and preserved left ventricular ejection fraction, submitted to echocardiogram and divided into three groups according to the combined analysis of E/e´ ratio and indexed left atrium volume: Group 1, if normal left ventricular filling pressures; Group 2, if increased left ventricular filling pressures and Group 3, if indeterminate left ventricular filling pressures. Two-dimensional speckle tracking was used to measure peak left atrial strain (LAS). Analysis of variance, Student’s t test and receiver-operator curve (ROC) were used in the statistical analysis. Results: We included 58 patients who had 61 ± 14 years old, 57% of whom were women, and had average left ventricular ejection fraction 62 ± 7%. Groups 2 and 3 had lower LAS than Group 1 (20 ± 5% versus 22 ± 6% versus 30 ± 8%, respectively, p = 0.004), but did not differ between them (p = 0.93). LAS was a good predictor of elevated left ventricular filling pressures (p = 0.026; area under the curve = 0.80), obtaining sensitivity of 60% and specificity of 80% with a cut-off value ≤ 20%. Conclusion: The findings suggest that the left atrial reservoir function of individuals with indeterminate diastolic function is similar to that of individuals with advanced diastolic dysfunction, rendering LAS the potential to support the reclassification of indeterminate diastolic function.

Published: April 2022

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited disease of the cardiac muscle characterized by right ventricular dysfunction (global or regional) with or without left ventricular (LV) involvement in the presence of histological evidence of the disease and/or electrocardiographic abnormalities according to published criteria. ARVC has age-dependent penetrance and is mainly characterized by episodes of ventricular arrhythmia that can progress to sudden cardiac death (SCD). The estimated prevalence ranges from 1:2,000 to 1:5,000, with a predominance in the Caucasian population and in people who practice strenuous exercise or competitive sports. Despite its low prevalence, ARVC represents approximately 5–20% of CSM cases in young people.

Background: The use of myocardial perfusion scintigraphy in asymptomatic patients remains restricted to very specific clinical situations, many of which are addressed in the appropriate use criteria (AUC) for myocardial perfusion scintigraphy. Objective: To critically analyze the application of these criteria in indicating the tests performed in asymptomatic patients of the Dante Pazzanese Institute of Cardiology, a population that is notably at high cardiovascular risk. Methods: The study selected asymptomatic patients undergoing myocardial perfusion scintigraphy to investigate ischemia.Indications for tests were classified as appropriate, inappropriate, or uncertain. A fixed low uptake, transient low uptake, or transient ischemic dilation were considered changed results. The statistical analysis assessed the correlation between the degree of recommendation of indications and the presence of changed test results. Results: From an initial selection of 2,999 medical records, 490 were considered asymptomatic and included according to the previously established inclusion criteria. Only 9.8% of the indications were inappropriate, while 61.4% were appropriate and 28.8% were uncertain. Fixed low uptake of the radiopharmaceutical occurred in 43.5% of cases versus transient low uptake in 16.1%. An appropriate or uncertain test request was a predictor of a changed test result in this population. Conclusion: The use of AUC for myocardial perfusion scintigraphy proved effective at predicting abnormal test results in an asymptomatic population at high cardiovascular risk, especially patients with uncertain indications, which may mean that some of the indications considered uncertain may be appropriate for a population at high cardiovascular risk.

Background: The assessment of intravascular volume and fluid responsiveness is challenging in the management of critically ill patients. Diagnostic methods of hemodynamic monitoring must be safe, reproducible, and practical. Objective: To describe the applicability of ultrasound indices of the inferior vena cava in the assessment of intravascular volume and prediction of fluid responsiveness in critically ill patients. Method: A systematic review performed of the PubMed®, Latin American and Caribbean Health Sciences Literature, and Scientific Electronic Library Online databases for articles published in the previous five years. The descriptors used were “inferior vena cava,” “ultrasonography,” “fluid responsiveness,” and “volume status.” Results: The search identified 13 relevant articles. The collapsibility index of the inferior vena cava was 25%–50% as the cutoff point for defining hypovolemia and showed applicability in predicting fluid responsiveness in patients breathing spontaneously with cutoff points of 25%–57%. In mechanical ventilation scenarios, the distensibility index of the inferior vena cava was more effective at predicting fluid responsiveness than the other measurements with variation of 10.2%–20.5%. The inferior vena cava/aorta diameter index was especially useful in the pediatric population for defining intravascular volume; however, in adults, there were many divergences in its applicability. Conclusion: The assessment of intravascular volume and fluid responsiveness through ultrasound indices of the inferior vena cava is applicable and safe for diagnosing and monitoring hemodynamic instability. However, studies of value standardization are necessary due to divergences in the cutoff points used in each index.

The article considers the main historical approaches to the concept of a welfare state. It is substantiated that despite different eras, it is a certain level of economic development in a particular country in the corresponding period that causes an objective need for a transition to a welfare state, acting as a kind of incentive for this process. But the goals and principles of the welfare state as a whole remain unchanged. Thus, the historical character of economic laws is manifested. As a specific example, the main directions of the modern socio-economic policy of the Republic of Belarus on the way to the formation of a welfare state are revealed.

The tax is the most important economic category that forms the basis of the tax system and the formation of the revenue side of the country's budget. In any socio-economic formation, taxes play a decisive role in the development of society, despite the changing forms of tax exemptions and their smooth flow from natural to value. At each stage of the development of society, the evolution of the forms of tax exemptions corresponds to the manifestation of the action of three philosophical categories: chaos — uncertainty — order. Since it is difficult to predict the nature of the development of society, it is necessary to be prepared for the fact that at some point the tax system is in chaos, it is replaced by some uncertainty that predetermines the emergence of order. Based on the definition of the concept of tax, presented in the Tax Code of the Russian Federation, its main structural elements are highlighted, using which the tax model is built. The model can be filled with additional and optional elements. The integration of these three groups of structural elements of the tax will make it possible to present its characteristics in the most complete way. The tax is not only the most important category of the tax system, but also a working category, which is emphasized by the manifestation of the action of its functions — fiscal, regulatory, stimulating, reproductive, control. The relationship of the selected functions is presented on the example of the use of the most important tax instrument — tax benefits. The tax should be considered as a living organism seeking self-development. Obviously, in the future, the forms of tax exemptions will be improved, and the tax itself and its model will have a more dynamic look.

MANY ARE CRYING, “WHO WILL SHOW US ANY GOOD?” – VOICES OF DECEMBER 2007 POST-ELECTION VIOLENCE VICTIMS IN KENYA
Authors: Mbutu Paul , Wanjigi Jimi
Published: April 2022

Purpose: This study analyzes and brings to light the voices of the victims who suffered particularly the socio-economic effects of the 2007 December violence and land clashes that took place in Kenya. During the 2007 December violence and land clashes, women, children and men were affected differently by the conflict, with women and children suffering most of the effects such as death, physical injuries and insufficient resources to take care of their basic needs. Consequently, as women experienced the immediate consequences of the conflict, they were the first to receive humanitarian assistance from international Non-Governmental Organizations (NGOs) like the Red Cross and a few indigenous ones. The voices of the victims narrating the violence they went through and the trauma they lived with would engage the minds of peace-caring persons to speak against violence of this nature in the future.

Methodology: Utilizing a qualitative study approach, the study focuses on 17 interview transcripts, statements taken from Kenyan newspapers of January 2008, online newspapers during the same period, eyewitness accounts as recorded in papers. For the theoretical framework, I used thematic analysis because these were stories “told” by the affected individuals.

Findings: My aim was to purposely establish how the rhetorical narratives as told by the affected individuals “chain out”. Are there any running main themes and patterns across the narratives? What is the “master narrative? What are the “counter narratives”, how are they constructed, and how do they attack the master narrative? One of the key issues I identified in my literature review as the cause of violence in Kenya is land. Violence was rampant and severe in the rich agricultural region of the Rift Valley.

Unique contribution to Theory, Policy and Practice: The study underscores the importance of listening to people’s voices and the stories as told by the victims themselves. Narrative framework and mainly thematic analysis framework helped in the analysis of the stories told by the violence victims. The country seemed to be polarized along ethnic lines – which to me, is a big deterrent for development. Politically, people need to be educated on their political rights and not be misused by politicians for their own advantage. The government, the judicial system, the church and the Electoral Commission of Kenya should address the issues raised by these traumatized and overwhelmed individuals.

Soil is a natural medium that is one aspect of supporting the life of all living things, including plants. Soil chemical properties greatly affect the growth process of oil palm plants, especially in the production process of oil palm fruit bunches. The purpose of this study was to determine the soil's chemical properties in oil palm plantations. The method used in this study is a descriptive method by conducting surveys and laboratory analysis. Soil samples were taken randomly at a depth of 0-20cm at four points of plantation land. Several parameters have been analyzed, such as pH, total N, CEC and exchangeable Al (Al-dd). Soil samples were analyzed at the Laboratory of Soil Research Indonesian Oil Palm Research Institute (PPKS) Medan. Determination of the criteria for assessing soil chemical properties based on the soil fertility standards issued by the Soil Research Center (BPT) Bogor (2009). The results of the analysis showed that the soil pH was slightly acidic, total N was low, CEC was low and Al-dd was very low.

Published: April 2022

A series of sisal fibre reinforced concrete roofing tiles were produced and tested using both standard methods and non-standard methods of testing corrugated Roman II tiles. The concrete was blended with ground granulated blast-furnace slag to various degrees to determine the optimum blend. The effectiveness of solar chamber curing was studied. The curing method was based on the utilization of solar energy to produce moisture movement in a sealed system with a chamber temperature that is significantly higher than the normal level in the surroundings. The failure modes and strengths of the tiles under bending load were presented and discussed. The effect of admixtures was also investigated on some of the samples. The viability of the techniques studied for commercial production of concrete roofing tiles was discussed.
