The challenges for Ukrainian theatre art in the years 2020-2022
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Korobko M. I.
Published: September 2022

The purpose pf the article is to monitor the challenges faced by Ukrainian theater during the global coronavirus crisis and the war in Ukraine in 2020-2022. During its long history, the Ukrainian theater has experienced various difficulties: bans (the Ems Act and the Valuev Circular in the 19th century), strict censorship (in the late 19th century and almost all of the 20th century), and two World Wars. General socio-cultural factors, political crises and, finally, war were also added to the background of the great theatrical crisis, which was present even before 2020. Responding to the challenges of the times, the theater searches for and develops new models of broadcasting and communication with its audience. But Ukrainian theaters, unlike their Western counterparts, were able to open in mid-2020 and more or less work in 2021. The XXI century was marked by difficult pandemics in 2020 and 2021 and the war in Ukraine (which lasted from 2014 in Donetsk and Luhansk regions, the occupation of Crimea and the spread of war throughout our country in 2022). In addition to objective geopolitical problems, there are problems of new political reforms, underfunding, and lack of professional staff (because the theater is not only actors and directors, but also educators, playwrights, and cultural audience, and various workers, whose audience not to see). All these factors have called into question the existence of even large professional theaters, not to mention smaller and unprofitable theaters. The theater is now in a particularly difficult situation, almost on the verge of extinction. Theatrical workers are trying to find new ways to express themselves and attract spectators, sponsors and funds in order to survive. They are looking for new genres, new drama, new themes for their performances. At the moment, almost all theater groups are trying to find non-standard forms of work: online screenings, immersion performances, open-air performances and more. The problems became bigger when the full-scale war started in February 24. However, Ukrainian theaters reopened their doors for spectators in April, after the month of total silence and non-action. And this fact gives us the hope for living.
Political party as a derivative of the TV show in contemporary Ukraine: cultural technology of image versus ideology
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Pavlova O. Y.
Published: September 2022

The author analyzed the TV show "Servant of the People" and how it influenced the functioning process of political parties in Ukraine through the prism of the correlation of ideological and technological practices in the TV show. The methodology of the study is based not on the analysis of the content of political programs and organizations, but on the logic of hierarchies and transformations of cultural practices. The main marker of the dominance of technology over ideology in the 2019 presidential elections in Ukraine was the fact that a political party is created with the same name after it became clear that the success of the show ensured the victory of the protagonist's representative in the elections. Mass media is a form of cultural power of an ever-expanding group of educated people. It combines the elements of ideology and technology of image. The historical dynamics of the mass media demonstrates several historical stages in this process. The first stage is the print media: the text-centrism of this media creates an ideological dominant for unifying into large enough groups of people at the cost of the regulative idea of rational discourse. The decentralization of political positions, represented as variety of political parties, is carried out as rational criticism. The second stage is optical media (cinema and television): the circulation of images from this period creates a positive emotional connection to the political leader beyond the mediations of the rational bureaucracy. The dramaturgical style of media criticism does not assume an active position of a rational subject, but a passive mass viewer, who expresses an evaluative position on professionally produced images, including images of the political sphere. The technology of image production dominates the ideological narrative. The third stage is the reproduction of optical media in Internet practices. Here the simplification of production and circulation, of discourse and image, leads to a new level of immediacy in the connection between the political leader and his voters, on the one hand. On the other hand, the political, as well as other elite spheres, are beginning to lose their privileged status in the democratization of cultural capital production. Internet media suggest a de-differentiation of image and discourse, ideology and technology of image. There is a certain imbalance towards the production of images above narrative.

Published: September 2022

The article considers the social preconditions and socio-cultural context of the formation of art practices as a cultural phenomenon of the XX century and identifies the causes and features of sectoral influence on other forms of activity in modern conditions of digitalization of social space. It is noted that the process, which reflected the binary stratification of high culture and "one-dimensional" (according to H. Marcuse) civilization, accumulated protests of the last century and formed in the structure of society field of practice – art practice, appears in modern culture in a new capacity construction of socially demanded spheres of interaction. Hypertext, interaction, co-creation, as characteristic features of the culture of postmodernism determine the principles and approaches of modern Internet, virtual, media practices. Network art practices, art projects, virtual exhibitions – what became possible with the beginning of digitalization, was a few decades ago rather an aesthetic experiment, marking the contours of creativity. The development of digital technologies, with which various spheres of activity are fused today, has formed fundamentally different conditions for the transit of practices, instant real implementation in various fields of human activity. The article provides examples of appeals to such areas of actualization of art technologies as education, psychology, social work and more. The article states that art practices, as a specific format of creativity of an experimental, interactive, dialogic nature, which absorbed various intentions of the culture of the XX century: protest moods, demarcation and at the same time borrowing of artistic traditions, acute presentation of social problems, etc., occupies a place in the development of information culture XXI century leading place in visualization of future prospects, new contours of digital civilization. However, the extent of their involvement was determined by factors of an individual, subjective nature. It is the information processes, network interactive communication, and the singularity of the fields of practice in various spheres of activity that determined the new order of introducing art practices into a wide spectrum of the sectoral development of society.
The problem of integrating Gender Studies and business ethics fields
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Lyubivaya M.-M.
Published: September 2022

usiness ethics is a branch of applied ethics that examines ethical principles and moral issues in or caused by business. Like other branches of applied ethics, business ethics has both a descriptive and a normative element. In its descriptive function, business ethics most often connects the work of the business world with the processes of markets, economic growth, profit, technological achievements, as well as the practice of organization and management. In its normative use, the business of business ethics is the study of the structures, policies, and principles that underlie the often taken-for-granted descriptive aspects of the business world and the associated behavior of individuals and organizations.

It is hard to imagine the horrors that took place during the Second World War. Concentration camps began to appear almost immediately after Adolf Hitler came to power in Germany. The goal of such camps is the isolation, slave exploitation and destruction of all whom the Nazis considered enemies of both the German people and the state itself. The worst thing is that the people who were taken to such camps had no idea what was waiting for them there. The term of their stay was indefinite, they left their homes, not knowing that they would never return to them. All that fear, pain, despair, misunderstanding is hard to comprehend and describe in words.

Features of subjective well-being of Russian and Chinese students: A comparative analysis of the problem
Authors: Pilishvili T. S. , Danilova A. L. , Savushkina A. I.
Published: September 2022

Introduction. The subjective well-being of students is an important factor affecting academic achievements and professional development. The number of Chinese students studying in Russia is already quite large, and there is a potential for growing cooperation between our countries. Therefore, the study of the subjective well-being of Chinese students in their comparison with Russian students is relevant not only from an academic point of view (as a cross-cultural study of the globalising world), but also from a practical point of view.

Aim. The aim of the present research is to theoretically and empirically study the subjective well-being in general and its individual components among Chinese students getting higher education in Russia, in comparison with Russian students there.

Methodology and research methods. The methodological principles of the study are activity-based and subject-activity approaches, as well as the principles of consistency and system analysis. The theoretical study was conducted using the bibliographic method. The empirical study used the testing method and methods of statistical data processing.

An empirical study was conducted on 392 students of the RUDN. The following psychodiagnostic methods were applied in the study: “Scale of Subjective Well-Being” by A. Perue-Badu (adaptation by M. V. Sokolova), “Questionnaire of Self-Attitude” (V. V. Stolin, S. R. Pantileev), “Oxford Happiness Questionnaire”, “Subjective Assessment of Appearance” (V. A. Labunskaya, E. V. Belugina), and “Scale of Basic Beliefs” by R. Yanov-Bulman (adaptation by O. Kravtsova). The statistical Mann-Whitney U criterion was used for the calculations. The calculations were performed using the IBM SPSS Statistics 23 program.

Scientific novelty and results. The scientific novelty and the most significant research results consist in identifying the features of subjective well-being and related personal characteristics of Chinese students studying at Russian universities, in comparison with Russian students there. It was found that most of the indicators of subjective well-being of Chinese students are at a lower level than those of Russian ones. The exception is the parameters “psychoemotional state” and “tension and sensitivity”, for which Chinese students show better scores.

Practical significance. The practical significance of this work is that the authors developed the recommendations aimed to improving the indicators of the subjective well-being of Russian and Chinese students studying in Russian universities.
Features of teacher’s reflection: Connection with personal and professional value orientations
Authors: Belolutskaya A. К. , Krishtofik I. S. , Mkrtchyan V. A.
Published: September 2022

Introduction. The development of professional reflection is determined by the nature of the activity in relation to which it is carried out. At the same time, teacher professional reflection is an effective resource for the development of educational activities. At the present stage, there is a wide variety of education models. Each educational model is characterised by its special values; reflection has its own special meaning, purpose, and result in a specific educational model.

Aim. The current research aims to present the authors’ model for studying the features of teacher professional reflection; to discuss the results of testing this research model, which made it possible to draw a number of conclusions about the presence and nature of the relationship between the level of teacher professional reflection and their personal and professional values.

Methodology and research methods. The present research is based on the activity approach, theoretical provisions on the structure and functions of reflection of activity, the meaning of reflection in various models of education, the types of professional pedagogical reflection. The research model is developed through the questionnaire method and the case method. The study involved primary and secondary school teachers of three educational complexes in Moscow (N = 63).

Results. It has been established that the values of the life and professional plan of the subjects are consistent with each other, and professional actions are generally not related to the declared professional values. The authors confirmed the hypothesis that the reflection of positional type has a significant positive relationship between the degree of congruence between the values declared in the survey and those manifested in solving problematic professional situations and the level of development of reflection of these types.

Scientific novelty lies in the development of a model for studying the features of professional reflection associated with the personal and professional values of the teacher. The results obtained in the course of its approbation can serve as a basis for understanding the mechanisms for the development of professional reflection of teachers in various models of education.

Practical significance. The developed methodology for studying the features of professional reflection of teachers can be used for the further creation of the set of tools for self-assessment and the development of professional pedagogical competence, the core of which is pedagogical reflection.

Introduction. Involvement of stakeholders into curricula modernisation in modern educational institutions has always been significant due to the existing misbalance between the social requirements and outdated educational materials.

Aim. The aim of the research is to analyse the three dimensions of stakeholder involvement into curricula modernisation in education on the basis of Kostanay regional university named after A.Baitursynov (Kostanay, Kazakhstan): maximal involvement, partial involvement, and formal participation.

Methodology and research methods. The research is based on the 10 sessions 1.5 h each organised on the platform of the virtual foresight laboratory (VFL) specially designed for the realisation of maximal involvement of the participants. Two in-depth face-to-face interview sessions with the focus groups (FG) participants (1 entry interview and 1 post-sessional interview) were organised and processed.

Results. The results of the sessions with 6 stakeholders represented focus group 1 that demonstrated the new maps of the future curriculum and modernised the text of the existing educational curriculum in terms of the goals, content and competencies requirements. The highlights include the following results of the study: the FG1 participants  indicated  their synergy in foreseeing the future through mapping, trends design and discussions  in VFL; there was the increase of the learning gain among FG1 stakeholders in terms of the structure of the curriculum, educational programme, types of competencies,  foresight research; the personal growth of stakeholder  involvement  into curricula modernisation  was directly observed, as their gained experience was reflected in further modernisation  of educational programmes  of other majors.

Scientific novelty. The research presents the key theoretical role of virtual foresight laboratory in curricula modernisation, basic theoretical issues on design of the future maps and foresight planning.

Practical significance. Practical outcomes in curricula modernisation can be adapted to any educational institutions aimed at perspective planning and foresight applications.
The Effect of Sumac Juice Given to Broilers by Drinking and Inhalation on Performance, Immunity Response and Some Blood Parameters
Authors: IZADEEN RASHEED Hersih , YURTSEVEN Sabri , BESKİ Sleman Said Mohammed
Published: September 2022

This study was planned to determine the effects of sumac juice and different application methods on the fattening and immune performance of broiler chickens. The study started with 240 Ross 308 broiler chickens at the age of 1 day. The trial model consisted of 6 groups in total, in the 3*2 interaction model, in which three different sumac levels were given in two different ways. Each group was arranged to contain 4 replications, and 10 broilers per replication. Birds were supplemented with three different levels (0, 5, and 10 g/liter) of sumac both in drinking water and via inhalation. This experiment lasted 42 days. Live weight and feed consumption were determined on the 10th, 24th, and 42nd days. On the 32nd day of the study, the chickens were vaccinated against infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) by adding them to drinking water for an immunity test. During slaughter, blood samples were taken for antibody titers, and hematological tests and lipid profiles were performed. It was observed that the additive of sumac given by drinking water or inhalation did not have a significant effect on the growth performance of broilers. However, steam application significantly reduced feed consumption and body weight gain. Sumac was not effective in reducing the lipid profile, particularly cholesterol, in the serum of broiler chickens. In addition, although the production of antibodies against NDV and IBV in broilers was improved to some extent, the antibody titer against IBV showed a significantly positive improvement with inhalation administration.

Published: September 2022

Academic health centers (AHC) both contribute to and are influenced by the communities they serve. As part of a central commitment to improving human health, there is a need for AHCs to acknowledge their history related to race and racism, the resulting impact on current health disparities, and the disparate treatment of racial and minoritized communities. As AHC’s care for Black and Brown communities, they have a unique responsibility to redress their respective legacies of bias, discriminatory practices, and experimentation without consent. One way to achieve this is to provide learning opportunities for in-depth engagement with students, faculty, staff, health care providers, and community members in conversations regarding racial equity, which are essential to shaping and impacting change at an individual and institutional level. Virginia Commonwealth University in Richmond, Virginia, launched a new initiative, History, and Health; Racial Equity, designed to (a) increase awareness of our institution’s history, impact, identity, and culture, and (b) support meaningful conversations around history, health equity, structural racism, and health sciences education. Urban and metropolitan universities may learn from and replicate this program and encourage such conversations in their communities.
Anchored or Detached? A Student Commentary on Equity, Diversity, and Inclusion at Urban Institutions
Authors: Parks Amanda , Scott Gerron , Seijo Chariz , Keys Troy
Published: September 2022

In 2020, Americans witnessed the COVID-19 pandemic disproportionately impact the most minoritized groups. Concurrently, the innumerable police killings of Black Americans re-ignited racial justice protests across the world. As a result, students, faculty, and staff observed a rapid push by administrations to enact diversity, equity, and inclusion (DEI) initiatives and commit to creating more equitable and inclusive climates. Since higher education's inception, urban anchor institutions have played an integral role in the political, social, and economic well-being of their surrounding communities. After 2020, as the distance between universities and their surrounding communities continues to expand, it’s as critical as ever for urban and metropolitan universities to dismantle the pervasive inequities that torment their students and surrounding communities. Although numerous anchor institutions have expressed their commitment to DEI initiatives in recent years, minoritized students, faculty, and staff continue to face systemic barriers to academic and professional achievement and overall well-being. Given this discrepancy, we, four graduate students from an urban anchor institution, were invited to provide recommendations for universities to dismantle inequities and provide a more inclusive, anti-racist environment for its students. As such, we address three concerns: increasing the diversity of faculty and staff, correcting housing and medical injustices of the past, and remodeling campus safety and policing. Our commentary also provides actionable steps for urban anchor universities to address these challenges, particularly for minoritized students and communities.

A 2-Phase Method for Solving Transportation Problems with Prohibited Routes
Authors: Ackora Prah Joseph , Acheson Valentine , Barnes Benedict , Takyi Ishmael , Owusu-Ansah Emmanuel
Published: September 2022

The Transportation Problem (TP) is a mathematical optimization technique which regulates the flow of items along routes by adopting an optimum guiding principle to the total shipping cost. However, instances including road hazards, traffic regulations, road construction and unexpected floods sometimes arise in transportation to ban shipments via certain routes. In formulating the TPs, potential prohibited routes are assigned a large penalty cost, M, to prevent their presence in the model solution. The arbitrary usage of the big M as a remedy for this interdiction does not go well with a good solution. In this paper, a two-phase method is proposed to solve a TP with prohibited routes. The first phase is formulated as an All-Pairs Least Cost Problem (APLCP) which assigns respectively a non-discretionary penalty cost M*ij <= M to each of n prohibited routes present using the Floyd¢s method. At phase two, the new penalty values are substituted into the original problem respectively and the resulting model is solved using the transportation algorithm. The results show that, setting this modified penalty cost ( M*) logically presents a good solution. Therefore, the discretionary usage of the M <= ∞ is not a guarantee for good model solutions. The modified cost M*<= M so attained in the sample model, is relatively less than the Big M ( <= ∞) and gives a good solution which makes the method reliable.
Rapid steering towards successful derotation- A novel technique using hypodermic needle
Authors: Sundareswaran Shobha , Mishra Navnita
Published: September 2022

Correction of rotated teeth requires significant time and efforts with conventional mechanics. Unwanted iatrogenic effects may also occur on the teeth adjacent to the rotated teeth if not undertaken correctly. The time taken for derotation of teeth can also add to the overall treatment time.

In this article, we are presenting a simple clinical technique using a hypodermic needle for faster and more efficient derotation of teeth. This technique has been found to be useful in correction of even severely rotated teeth.
“Era of Prophylaxis”: KGB Practices in Work with Religious Organizations during the “Khrushchev period” (Based on Leningrad Materials)
Authors: Boldovskiy Kirill
Published: September 2022

The article is devoted to the analysis of the participation of state security agencies in the anti-religious campaign of the “Khrushchev period”. The main emphasis is placed on 1959—1964, the time when new approaches to this issue were being formed in the KGB. In the first part, the author focused on the struggle of the KGB against illegal, i.e. not passed state registration, religious movements. The second part is devoted to the eradication of any uncontrolled trend within official religions, as well as the participation of security officers in anti-religious propaganda. The author paid the main attention to the application of a new method of combating dissent — the so-called “prophylaxis”. The main sources for the study were reports on the work done by the KGB Leningrad Department to the leading party bodies, as well as articles published in specialized journals. The author makes a number of conclusions about the degree of effectiveness of the KGB work with believing citizens and the reasons of such a great interest in the religious life of citizens.
“Measures to Further Compromise Continue”: the Information Potential of the Special Messages of State Security Agencies in the 1950s and 1960s (Based on the Materials of the Tyumen Region)
Authors: Kliueva Vera
Published: September 2022

The article is devoted to the analysis of information content of regional materials on the religious landscape of the Tyumen region. The article is based on documents from the fund of state security agencies deposited in the state archive of the socio-political history of the Tyumen region. Researchers can work with documents dated earlier than 1964. The materials describe a variety of methods of working with different faiths. In addition, the available data contain statistical information and socio-demographic characteristics of believers. Descriptions of religious practices and religious everyday life have been preserved. It is concluded that the materials of the regional state security agencies are an important source in the context of a lack of information about the religious situation in the Soviet provinces in the post-war USSR.

Review of Cleaning Methods for Solar Cell Array
Authors: Satheesh N.
Published: September 2022

With the fossil fuels in the verge of exhaustion, the renewable sources are being seen as the prospective potentials for energy, the solar photo voltaic technology is one such source that can look up. One of the problems in installing solar energy is pollution/dust and reduces the efficiency of the photovoltaic cell and major power loss when unwanted obstructions cover the surface of the panels. The obstruction turns the shaded cell into a resistor, causing it to heat up and consume extra power. There is urgency in improving the efficiency of solar power generation, to address this issue, we have discussed about self-cleaning solar panel, and different types of mechanical cleaning technology for solar panels in this paper.A transparent electrode material such as indium tin oxide delivers an alternating current to the top surface of the panel. As it swings between being positively and negatively charged, it creates an electric field that repels charged particles/dust.A fully automated, simple mechanical design use a rotating brush made up of soft microfiber in conjunction with air blowers which will remove all dust without water and without scratching.A nano-coating with hydrophobic and self-cleaning properties for photo voltaic panels, the coating’s effect stops dust and bird faeces from sticking to PV panels, keeping them clean, maintaining their efficiency.

Risk Management of Staff Training
Authors: Zeng Yue-zheng
Published: September 2022

As an investment to the enterprises, staff training has both risk and income. So the risk management of staff training turns to be a key link of the human resources management work in the enterprise. In this paper, starting from the connotation of employee training risk management, it is shown that the main reasons of employee training risk are as follows: the wrong idea, the imperfect training system, unreasonable training technology, loss of talents, cultivating the competition, enlargement of professional and technical secrecy, and the time lag of getting training benefits. Aimed at different causes of the staff training risk, the measures to prevent the occurrence of risk or reduce the loss of training risk to minimum are put forward. They are establishing a correct concept of staff training, building the effective training system, adopting appropriate training technology, preventing the loss of employees after training, strengthening the protection of enterprise technical and commercial secrets, eliminating or reducing devaluation of training project value.

Authors: Bidaki Reza , Zarnegar Fatemeh , Saghafi Fatemeh
Published: September 2022

Health concerns, changes in lifestyle, job losses, economic hardships, and the death of family members during the Covid-19 pandemic have led to depressive disorders. Here, a 39-year-old man referred to a psychiatric clinic with the complication of depressed mood, which was exacerbated by stress, anxiety, restlessness, and insomnia. In addition, he was referred to a cardiologist and dermatologist because of uncontrolled tachycardia and urticaria. After detailed examination, the final diagnosis was COVID-19, along with anxiety disorder and dermatological diseases.
Since the Coronavirus disease (COVID-19) can cause stress and psychological problems, it can disrupt the patient's healing process if ignored. On the other hand, there seems to be a strong association between psychiatric illnesses with COVID-19 and urticaria that can be investigated.
Emergency operation of redo second and third mitral valve regurgitation in a patient with a history of the mitral valve prosthesis, coronary artery bypass graft surgery, and moderate aortic regurgitation: a case presentation
Authors: Khalili Ahmadali , Faravn Amir , Parizad Razieh
Published: September 2022

Redo cardiac surgery is usually more complex than initial surgery and has a higher risk of mortality due to the risks associated with sternotomy.
Thoracotomy is a procedure through which easy access to the heart and valves is possible, taking less time. There is no need to release the adhesions of the previous operation. In addition, there is no possibility of heart rupture and unstable hemodynamics in the second CABG operation.
Safe peripheral Cardiopulmonary bypass (CPB) access and right thoracotomy are preferred in patients with unstable hemodynamics with a history of CABG and mitral valve replacement (MVR) surgery.
A 60 -year old man with a history of prosthetic MVR, CABG, and right-hand paresis due to cerebrovascular accident (CVA) was referred to Madani Hospital in Tabriz, Iran (2020). Transthoracic echocardiography (TTE) revealed signs of severe dysfunction of the prosthetic mitral valve (PMV). Whereas, on anticoagulation, a left ventricular ejection fraction (LVEF) was about 40%, and the patient had mild to moderate aortic regurgitation (AI). The patient underwent an emergency redo MVR operation using the thoracotomy techniques and coronary intervention (hybrid procedure). After two weeks, TTE showed a decreased mobility of one PMV leaflet, and the patient did not respond to full anticoagulation. Therefore, the third surgery was performed.

Objectives: Coronary artery revascularization is the standard treatment for patients with severe left main coronary artery disease (LMCAD). In cases where the patient refuses surgical revascularization or PCI, medical treatment will be the only option. The purpose of this study was to compare the one-year outcomes of patients with (LMCAD) in terms of surgical or medical treatment.
Methods: This prospective cohort study was conducted on 139 patients (91 men and 48 women) with severe left main coronary artery disease who were diagnosed by coronary angiography from 1st Mar 2014 to 28th Feb 2014. Patients were followed up for one year as to major adverse cardiac and cerebral events (MACCE) including death, non-fatal myocardial infarction, stroke, and hospitalization.
Results: From total of 2661 coronary angiographies, 139 patients (5.2%) with a mean age of 63.2±7.2 years had LMCAD. The mortality rate in the medical treatment group and the surgical group appeared to be 16.7% (6 cases) and 8.7% (9 cases) respectively (p =.156). The rate of stroke in the medical group turned out to be 5.6% (n=2) and in the surgery group 2% (n=2) (p =.27). The rehospitalization rate was 19.4% in the medical treatment group but 4.9% in the surgical group (p =.013). During one year, the survival rate was significantly lower in the medical group than the group undergoing coronary artery bypass graft surgery (58.3% vs. 84.5%) (p =.002).
Conclusions: In the short term, the optimal medical treatment of patients with LMCAD was not significantly different from that of CABG patients in terms of fatal cardiac and cerebral events. However, rehospitalization was more common due to recurrent angina pectoris.

Objectives: Heart failure is one of the most common chronic cardiovascular diseases, which often triggers disability or death. Health-related Quality of life (HRQoL) is one of the most critical factors in deciding how to treat these patients. In this study, we want to figure out the effect of different factors on the quality of life in patients.
Methods: This cross-sectional study was performed on 129 patients with heart failure referring to the center of Afshar Hospital in Yazd City, Iran 2017-2018. The standard (Shot Form survey) SF-36 questionnaire was used to measure different dimensions of quality of life.
Results: In the present study, 77 men and 52 women with heart failure were included and the relationship between comorbidities, heart failure classification factors, age, sex, and history of hospitalization with quality of life was measured. The result revealed a significantly higher quality of life in patients under 50 years (P = 0.005) as well as in men (p<0.001). And in the total population, the average quality of life appeared to be 45.46.
Conclusions: Quality of life in patients with heart failure is related to gender and age, so in women over 50 years, the quality of life proved lower but not related to factors such as, hospitalization, type of failure and stage of the disease. Among diseases related to heart failure, only people with high blood pressure showed lower quality of life scores. The total quality of life index score among our subjects was reported to be moderate to low.

Objectives: Children are the most important asset in any country. Since cardiovascular diseases are built up little by little from childhood, this study attempted to detect the relationship between psychological, spiritual, and social health conditions and cardiovascular risk factors in children.
Methods: This study is a cross-sectional study performed on 1035 children aged 6-18 years by multi-stage random cluster sampling in 2016 in Yazd province of Iran. The lifestyle questionnaire (LSQ) was used to collect data. In addition, demographic information (i.e., age and sex) and cardiac risk factors were measured. Logistic regression and t-test were used to analyze the data.
Results: In this study, by increasing the mean score of psychological and spiritual health, fasting blood sugar (FBS) decreased significantly (OR = 0.14, 95% CI: 0.02-0.80, P trend = 0.003 and OR = 0.05, 95% CI: 0.01, -0.28, P trend = 0.013). Also, with increasing the mean score of spiritual health, body mass index (BMI) reduced significantly too. (OR = 0.35, 95% CI: 0.18-0.66, P trend = 0.014). However, social health failed to be significantly associated with cardiac risk factors.
Conclusions: FBS in children aged 6-18 years is affected by psychological and spiritual health. BMI and the level of spiritual health also turned out to be inversely related. As a result, psychological and spiritual health dimensions should be improved to lower the risk factors for cardiovascular diseases in children aged 6-18 years.

Objectives: An accurate non-invasive evaluation of coronary artery disease (CAD) is essential in choosing the right management plan. Dobutamine stress myocardial perfusion imaging (MPI) is a substitute test for patients who cannot exercise. This study aimed to assess the relationship between dobutamine-induced hypotension and risk stratification of annual hard cardiac events evaluated by MPI.
Methods: This study is a retrospective study conducted on 1004 patients from October 2015 to august 2019.These patients referred to Rasoul Akram Hospital, because they could not exercise electrocardiography or had contraindications to vasodilator therapy, they were subjected to dobutamine Tc99m-Sestamibi single photon emission tomography (SPECT) protocol. During the protocol, blood pressure was measured with a one-minute interval.  From among the participants, 247 patients had decreased blood pressure by more than 20 mmHg during infusion. Then for patients, a gated MPI scan was performed, and  MPI with a quantitative and visual interpretation determined the risk stratification of the patients. Multivariable logistic regression model assessed the associations between decrease in blood pressure (above 20 mmHg) and risk stratification.
Results: A total of 1004 patients with a mean age of 59.07 years were studied. Of these patients, 247 had > 20mmHg drop in systolic BP from baseline. This study revealed a significant correlation between hypotension during the dobutamine stress test and high-risk scan patterns in myocardial perfusion scan. Moreover, there was a significant correlation between age increase, smoking, diabetes mellitus, transient ischemic dilation (TID), high baseline blood pressure, and history of CABG or angioplasty with a high-risk scan pattern in MPI.
Conclusions: This study demonstrated that hypotension during the dobutamine stress test is correlated with high-risk scan patterns in MPI.

Objectives: Cardiovascular diseases are the most critical causes of mortality in the modern world. Additionally, most acute coronary events result from sudden thrombosis leading to atherosclerotic plaque rupture. Computerized tomography (CT) angiography can identify the characteristics and quantity of plaques. This study investigated the relationship between plaque and moderate coronary stenosis.
Methods: This study was a retrospective diagnostic study comprising 91 patients who had been referred to CT angiography at Afshar Hospital in Yazd City, Iran, from 2017 to 2018 and undergone coronary angiography CT while bearing moderate coronary artery stenosis. Using the CT report, location, plaque density, the extent of stenosis, and vein involved were all extracted and recorded. The patients were followed up for one year from the time of the CT scan using the MACE questionnaire. Ultimately, data was analyzed using SPSS software version 22 through Chi-square, Fisher's exact test, and t-test.
Results: The results revealed the mean age of the patients to be 62.76±1.08 years; 39 (42.9%) women and 52 (57.1%) men. Based on the obtained results, the most common involved vessel, location of stenosis in CT angiography, and plate density included the left anterior descending artery with 75.8%, the middle part of the left anterior descending artery with 29.7%, mixed density with 54.9% and one segment with 62.6% frequency. Also, according to the significant adverse cardiac event (MACE) questionnaire results, the frequency distribution of cardiovascular events in the studied patients did not exhibit any evidence of cardiovascular events in the patients' one-year follow-up.
Conclusions: There was no evidence of cardiovascular events in the patients with moderate coronary artery stenosis during a 1-year follow-up.
