Mathematical model of transition of a production enterprise to a circular economy
Authors: Saraev Leonid A. , Тalikina Marina E.
Published: July 2021

In the published article, a mathematical model of an enterprise is proposed, the production activity of which is described by two production functions. The main production function converts resources into the products of an enterprise, the additional production function turns resources into its waste, which are usually included in costs. Enterprises of a waste-free circular economy organize their own production so that the waste of an enterprise becomes new production factors and is completely converted into additional useful products. The process of transition in time of an enterprise of an ordinary economy to an enterprise of a waste-free circular economy is described using a special dimensionless transformation function, which varies from zero to one. Two variants of the peculiarities of changes in the economic indicators of an enterprise that arise during the transition to waste-free production are considered. In the first case, a one-factor manufacturing enterprise was investigated, which in its production activity uses only one resource, which integrates the volumes of factors of production consisting of fixed capital, production assets involved in the production of labor resources, used in the production of materials, applied technologies, of various kinds innovation. In the second case, a two-factor manufacturing enterprise has been investigated, which in its production activity uses two resources, the first of which is fixed capital and production assets, the second production factor includes labor resources involved in production. Regularities have been established for changes in the time of production, waste, profits and costs of an enterprise when introducing waste-free technologies for the case of one-factor production. Anumerical analysis of the obtained economic and mathematical model shows that the maximum value of the enterprise's profit changes over time and corresponds to the level of the introduced circular technologies.

Authors: Tolmacheva Ekaterina A. , Podbornova Ekaterina S.
Published: July 2021

Indirect taxes play an important role in the Russian tax system, one of which is VAT. Value added tax is one of the most complex taxes in the Russian tax system. The article is devoted to the study of changes in budget income from the increased VAT rate. A comparative analysis of changes in budget income from an increased VAT rate is carried out. The list of basic and special indicators of changes in budget income from the increased VAT rate has been clarified. Particular attention is paid to the facts that have a significant impact on changes in budget income with an increased VAT rate. VAT is capable of ensuring the stability of the entire Russian system of public finance in the long term, not to mention the fact that stability is especially important in a crisis. Therefore, any steps to change the tax, especially in the direction of increasing, should be carefully calculated from all possible points of view, and not only from the side of additional income to the budget. In this regard, the objectives of this study are to determine the significance of factors affecting the quality of VAT administration, to identify the main constraints that reduce the efficiency of VAT collection in the OECD countries and Russia, and to develop recommendations for improving the quality of VAT administration in Russia.

KRITARCHY AS A SPECIAL FORM OF STATE (ON THE EXAMPLE OF SOMALIA)
Authors: Makutchev А. V.
Published: July 2021

The article analyzes the characteristic features of kritarchy a specific structure of society based on the power of the courts. Experts consider kritarchy primarily as a social or legal system, and some consider it a political regime. The author of the article attempted to study kritarchy as a form of state, a set of political and legal components (methods of organization of higher authorities, territorial structure of power, ways of its implementation) that can replace the usual forms of state in traditional societies. Kritarchy is considered a historical form of social and state structure that is not found today. Nevertheless, Somalia from the late 1980-ies to the present day, according to the author, is a modern example of kritarchy. In a weak, failed state, Somali society returned to a traditional way of life that created the basis for kritarchy. The author analyzes the courts as a substitute for the standard system of government, Somali law (a synthesis of customary and Islamic law) as an analog of standard legal systems, it demonstrates the viability of kritarchy as a form of state in the absence of traditions of usual forms of state in society.
ROLE OF THE REFORMS OF THE 1550-IES AS INSTITUTIONAL ANTI-CORRUPTION MEASURES
Authors: Fomenko R. V.
Published: July 2021

The article considers the prerequisites for the implementation, nature and significance of institutional measures to counter corruption at the local government level in Russia during the reforms of the 50-ies of the XVI century. The problems of evolutionary development or deliberated formation of new ways of combining public and private interests at the local level, interchangeability and complementarity of different forms of state administration, regional and local self-government are put. The article shows that in the search for ways to counteract abuse by vicegerent, the Central government gives wide powers to the bodies of local self-government. But the state will be able to completely abandon the vicegerent system only by the beginning of the XVII century. In turn, corruption costs were also evident in the activities of local authorities, which forces the state to create additional internal institutional mechanisms, and to impose anti-corruption expectations on new bureaucratic bodies voivodes, which were becoming a local continuation of the prikaz system.

INFLUENCE OF FAMILY AND KINSHIP RELATIONS ON THE IMPLEMENTATION OF CERTAIN INSTITUTIONS OF CRIMINAL PROCEDURE LAW: PROBLEM STATEMENT
Authors: Shestakova L. A.
Published: July 2021

The author of the article establishes the mutual influence of criminal proceedings, the interests of the family, minors, morality, political, religious, corporate and other social norms. The norms of criminal procedure law regulate a wide mound of public relations. These relations often have no connection with the criminal procedure form. Social norms often have a regulatory role in the sphere of criminal procedural relations. The Russian legislator does not take this circumstance into account. The law has lost its connection with other socio-cultural systems (morality, religion). Family relations signifi cantly change the content of all stages of the criminal process. Value and moral attitudes affect the legal position of participants in criminal proceedings. The state musts to accept the opinion of the Russian population about justice and morality. This opinion of the people should be consolidated in the Criminal Procedure Code. There is not a legislative mechanism to implement this idea. This circumstance interferes with the accounting of family relations in criminal procedure law.
Duchowość miłosierdzia według papieża Franciszka
Authors: Chmielewski Marek
Published: July 2021

Za sprawą ostatnich papieży, a szczególnie Franciszka, charakterystycznym rysem Kościoła katolickiego w trzecim tysiącleciu jest kult miłosierdzia Bożego. Domaga się on kształtowania odpowiednich postaw duchowych, które we współczesnej teologii duchowości opisuje się przez wskazanie na ich aspekt poznawczy, aksjologiczno-afektywny i praktyczno-działaniowy.

Tematyka miłosierdzia tak głęboko przenika życie Kościoła, że można mówić nie tylko o duchowości miłosierdzia, ale o miłosierdziowym wymiarze duchowości chrześcijańskiej.

Kult Bożego miłosierdzia jest ściśle związany z liturgią, dlatego – zwłaszcza liturgia eucharystyczna – ma również miłosierdziowy wymiar. Kształtowanie postaw miłosierdzia znajduje więc w niej swe źródło.

Особенности формирования половозрастной идентификации у детей дошкольного возраста
Authors: Лифенко И.И.
Published: July 2021

Проблемой сходства и различий в психологии мужчин и женщин занимаются уже несколько поколений ученых. Воспитание детей без учѐта особенностей биологического пола способствовало и способствует тому, что немало молодых людей в силу отсутствия у них основополагающих представлений о «мужественности» и «женственности» и при отсутствии полового воспитания в совокупности с конфликтными ситуациями в процессе принятия своей гендерной роли погружаются во внутриличностные конфликтны и живут в разрез с установленными нормами общества. Изучение процессов формирования гендерной идентичности поможет направить половое воспитание в нужное русло. От этого многое зависит в формировании будущей личности, а именно: уверенность в себе, наличие устойчивых личностных установок, и в итоге эффективность общения с людьми, благополучие семейных отношений.

Authors: Sadeghi Roxana , Toloui Amirmohammad , Pourhoseingholi Asma , Taherpour Niloufar , Sistanizad Mohammad , Omidi Fatemeh , Haji Aghajani Mohammad
Published: July 2021

Introduction: The correlation between echocardiographic findings and the outcome of COVID-19 patients is still under debate.
Objective: In the present study it has been endeavored to evaluate the cardiovascular condition of COVID-19 patients using echocardiography and to assess the association of these findings with in-hospital mortality.
Methods: In this retrospective cohort study, hospitalized COVID-19 patients from February to July 2020 with at least one echocardiogram were included. Data were extracted from patients’ medical records and the association between echocardiographic findings and in-hospital mortality was assessed using a multivariate model. The findings were reported as relative risk (RR) and 95% confidence interval (95% CI).
Results: Data from 102 COVID-19 hospitalized patients were encompassed in the present study (63.7±15.7 mean age; 60.8% male). Thirty patients (29.4%) died during hospitalization. Tricuspid regurgitation (89.2%), mitral valve regurgitation (89.2%), left ventricular (LV) diastolic dysfunction (67.6%), pulmonary valve insufficiency (PI) (45.1%) and LV systolic dysfunction (41.2%) were the most common findings on patients’ echocardiogram. The analyses of data showed that LV systolic (p=0.242) and diastolic (p=0.085) dysfunction was not associated with in-hospital mortality of COVID-19 patients, while the presence of PI (RR=1.85; 95% CI: 1.02 to 3.33; p=0.042) and patients’ age (RR=1.03; 95% CI: 1.01 to 1.08; p=0.009) were the two independent prognostic factors of in-hospital mortality.
Conclusions: It seems that LV systolic and diastolic dysfunction was not associated with in-hospital mortality of COVID-19 patients. However, presence and PI and old age are possible prognostic factors of COVID-19 in-hospital mortality. Therefore, using echocardiography might be useful in management of COVID-19.
Pregnancy and Childbirth During COVID-19 Pandemic: A Case Series and Review of Literature
Authors: Rahmani Shaghayegh , Norkhomami Sonia , Shahi Behzad , Keykha Mahjoubeh
Published: July 2021

Introduction: In March 2020, the World Health Organization introduced the Coronavirus disease 2019 (COVID-19) pandemic as a global health concern and predicted that without any changes in the transmission process, the disease would reach its peak in April. Hence, it was not unreasonable to expect the referral of pregnant women in all trimesters. Since respiratory illnesses can increase the risk of infectious diseases and maternal mortality, it is justifiable to consider COVID-19-positive cases as high-risk pregnancies.
Case presentation: The present study introduced six pregnant women with COVID-19 and discussed the points to consider in managing these patients.
Conclusions: Pregnant women are at increased risk in all epidemics of infectious diseases due to their physiological and immunological changes. Moreover, the safety of the fetus is another important issue to consider.
Accuracy of SARS-CoV-2 Detection in Saliva for COVID-19 Diagnosis: A Systematic Review and Meta-Analysis
Authors: Elkady Dina M. , Abdella Walid Shaban , Abdella Muhamed , Kopeya Abdelrahman Elsayed , Hamdallah Aboalmagd
Published: July 2021

Context: There is an unmet clinical need to develop simple, easy, rapid, and accessible testing for the detection of SARS-CoV-2. Recent reports suggested that saliva may be a host for the virus. The existence of SARS-CoV-2 in saliva can be associated with oral manifestations in infected patients. A systematic review was conducted as well as a meta-analysis to evaluate the diagnostic accuracy of detecting SARS-CoV-2 in saliva and investigate the association between positive saliva test and oral manifestations of COVID-19.
Evidence acquisition: A literature search in MEDLINE via PubMed, Scopus, Web of Science, and Cochrane was done in June 2020 and updated in February 2021 using relevant keywords. We screened studies for eligibility. The extracted data were analyzed using Meta-Disc software.
Results: Eighteen studies were included. Pooled data from eligible studies showed that the sensitivity of diagnosis of SARS-CoV-2 in saliva was 0.86 (95% CI, 0.83–0.89), and the specificity was 0.98 (95% CI, 0.96–0.98). COVID-19 was associated with oral diseases as amblygeustia, dry mouth, dryness, inflammation of the mouth, and enlargement of lymph nodes in the submandibular regions.
Conclusions: Our results showed that the saliva has a high accuracy in the detection of SARS-CoV-2.

Published: July 2021

Background: Alterations in sperm mitochondrial DNA (mtDNA) affect the functions of some OXPHOS proteins which will affect sperm motility and may be associated with asthenozoospermia. The purpose of this study was to investigate the correlation between 7599-bp and 7345-bp sperm mtDNA deletions and asthenozoospermia in Jordan.
Methods: Semen specimens from 200 men including 121 infertile and 79 healthy individuals were collected at the Royal Jordanian Medical Services In-vitro fertilization (IVF) units. The mtDNA was extracted followed by mtDNA amplification. Polymerase chain reaction (PCR) was conducted for the target sequences, then DNA sequencing was performed for the PCR products. Chi-square, Fisher's and Spearman's tests were used to calculate the correlation. 
Results: The results showed a significant correlation between the presence of 7599-bp mtDNA deletion and infertility where the frequency of the 7599-bp deletion was 63.6% in the infertile group compared to the fertile 34.2% (p<0.001, (OR=3.37, 95% CI=1.860 to 6.108)). Additionally, the sperm motility showed a significant association with the frequency of the 7599-bp deletion (p=0.001, r=-0.887). The 7345-bp mtDNA deletion showed no assoctiation with the infertility (p=0.65, (OR=0.837, 95% CI= 0.464-1.51)) or asthenozoospermia (p=0.98, r=0.008).
Conclusion: We demonstrated a significant correlation between asthenozoospermia and the 7599-bp mtDNA deletion but not the 7345-bp mtDNA deletion in the infertile men in Jordan. Screening for deletions in sperm mtDNA can be used as a pre-diagnostic molecular marker for male infertility.

Published: July 2021

Background: The purpose of this study was evaluating the relationship between fatty acid (FA) intakes and the Assisted Reproductive Technique (ART) out-comes in infertile women.
Methods: In this descriptive longitudinal study, a validated food frequency questionnaire (FFQ) was used to measure dietary intakes among 217 women with primary infertility seeking ART treatments at Isfahan Fertility and Infertili-ty Center, Isfahan, Iran. The average number of total and metaphase II (MII) oocytes, the fertilization rate, the ratio of good and bad quality embryo and bio-chemical and clinical pregnancy were assessed. Analyses were performed using mean, standard deviation, Chi-square test, ANOVA, ANCOVA, logistic regres-sion.
Results: A total of 140 women were finally included in the study. There was a positive relationship between the average number of total and MII oocytes and the amount of total fatty acids (TFAs), saturated fatty acids (SFAs), monoun-saturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), linoleic ac-ids, linolenic acids, and oleic acids intakes, while eicosapentaenoic acids (EPAs) and docosahexaenoic acids (DHAs) intakes had an inverse relationship. Consuming more amounts of TFAs, SFAs, PUFAs, MUFAs, linoleic acids, and oleic acids was associated with the lower fertilization rate, whereas the con-sumption of linolenic acids and EPAs increased the fertilization rate. The ratio of good quality embryo was directly affected by the amount of PUFAs intakes. Additionally, there was a negative correlation between the amount of SFAs in-takes and the number of pregnant women.
Conclusion: TFAs, SFA, PUFA, and MUFA intakes could have both beneficial and adverse impacts on ART outcomes.

Published: July 2021

Background: Uterine leiomyomata (UL), commonly known as uterine fibroids, are benign smooth muscle tumors of the myometrium. They cause pelvic pain, abnormal uterine bleeding, and infertility in women of reproductive age. The ovarian hormone estrogen is the main stimulator for the fibroid growth. The etiology is not yet clearly understood; however, UL are believed to be monoclonal tumors arising from a common progenitor cell. Chromosomal cytogenetic abnormalities have been demonstrated in 40-50% of the fibroids. The most frequent tumor specific genetic alterations in UL were identified in exon-2 of Mediator Complex Subunit 12 (MED-12).
Methods: In the present study, twenty-two multiple fibroids were evaluated both from the same uterus and from different uteri, of four women, for somatic mutations in hotspot region of MED-12. The tissue DNA of the UL's was isolated, amplified by PCR visualized on gel and sent for Sanger sequencing.
Results: The results indicate several variants in exon-2 and flanking intronic regions, seven exonic variants and five intronic variants which provide evidence that multiple UL in the same uterus may not be clonal in origin.
Conclusion: This study indicates genetic heterogeneity. UL may not have a clonal origin, these exon-2 variants of MED-12 gene could be involved in UL progression.

The purpose of this study was to evaluate the threshold of inflation that is tolerant of Indonesia’s economic growth rate. The basic question to be answered was what level of inflation is safe enough for economic growth. To answer this question, this study used Indonesian macroeconomic data, specifically data on inflation and economic growth between 1969-2017 sourced from the Central Statistics Agency and Bank Indonesia. The data analysis method used was a threshold regression model that was repeated manually by entering an acceptable inflation simulation value based on inflation experience in Indonesia. The simulation results showed that the inflation threshold that is safe for growth is around 7 to 8 percent per year. However, the model showed that inflation of 3 percent is the optimal level for growth. One concludes that an inflation rate of around 3 percent can be used as a guide in determining the inflation target in Indonesia.

Entrepreneurial Motivation in the Fourth Industrial Revolution
Authors: Wardani Shanti Ike , Latifah Nunuk
Published: July 2021

This study aimed to analyze the entrepreneurial motivation of members of Pemberdayaan Kesejahteraan Keluarga (PKK) in the Trenggalek Regency during the fourth industrial revolution. A descriptive qualitative approach was used. Data collection involved interviews and triangulation techniques. The results indicated that people are motivated to start a business because there is the hope of making a profit to meet their needs. By being an entrepreneur, a person is free to carry out their affairs in their way, enjoy their profits, gain additional income, and be free of the rules of the organization/company, intervention or influence of others. Also, people want to be an entrepreneur because they have a sense of pride in being able to be independent in making capital, managing supervision and being a leader for themself, and trying to get out of the challenges of their life without expecting help from others. However, people who try to become entrepreneurs in the fourth industrial revolution face challenges. It is necessary to increase the government’s participation in creating new entrepreneurs to face these challenges. One approach is providing training to equip the community with skills and abilities in utilizing the resources they have. It is important to change the mindset of the community to become entrepreneurs.

Praying Rooms in Shopping Centres: Are They Important?
Authors: Retnosary Rieke , Salleh Nor Zafir Md , Masruroh Siti
Published: July 2021

The majority of Indonesia’s population are Muslims who must perform the obligatory five prayers daily in which the prayer times have been determined. Shopping centres can encourage ease of worship for Muslim visitors by preparing a praying room to make them feel comfortable and linger longer in the shopping centre, which positively impacts economic development. In this study, 85.3% of respondents selected praying rooms as the most important category compared to the other three categories in shopping centres. A questionnaire, observations and interviews were conducted in a shopping centre in Kabupaten Karawang as a case study to corroborate these initial findings, to determine if religious facilities are essential for Muslim visitors. Praying rooms are important for visitors, especially to promote cosiness for worship, and after praying, visitors can decide to stay and spend more time in the shopping centre. The respondents reported that the provision of worship facilities would benefit the management and tenants/outlets which offer products because the visitors linger in the shopping centre, increasing the products purchased.

The COVID-19 pandemic has a very broad impact. This pandemic not only affects health, but also education. This is because measures to prevent the spread of the virus require the application of physical distancing. With the application of physical distancing, conventional learning in the classroom cannot be implemented, so distance learning media is needed to continue the teaching and learning process. Learning media in an educational context is a very strategic instrument that helps determine the success of the teaching and learning process. This is because with their limitations, humans are often less able to capture and respond to things that are abstract or that have never been recorded in their memory. Media can support learning by providing a deeper understanding of the material being discussed. This study aimed to design, build and test a business simulator application integration system (SIMBIZ-Integrated) as a distance-learning medium that could help the learning process which has been disrupted due to the COVID-19 outbreak. In addition, this research examines the current conditions of media utilization in distance learning and the effectiveness of the use of business application media in introductory business courses.

Malang is one of the cities that supports the creation of a competitive creative economy. There are a number of industrial clusters spread throughout the Malang area, one of which is the Sanitair cluster. Industry security in Malang was very high before the COVID-19 pandemic. The COVID-19 pandemic has caused a decline in the economy and in activity in the creative economy sector in Malang, including in the Sanitair industry cluster. The economic shock caused by the COVID-19 pandemic gradually subsided as the stability of the domestic financial market and economic sectors stretched. However, the supply and demand sides of the industry were both hit, so recovery efforts still need more time. The spread of the virus also has not shown signs of ending along with the increasing trend of cases and confirmed deaths. The demand for various social and economic activities is getting stronger, marked by loosening of physical distancing in many areas. On the other hand, the existing public health infrastructure is still inadequate. So, there is a high risk to moving back the various wheels of social and economic activity in the Sanitair industry cluster in Malang. COVID-19 affected the supply chain of the SME industry, including the absorption of products, the availability of raw materials, suppliers and the distribution process of the Sanitair industry.
