Authors: O. A. Kovalishin
Published: December 2020

The main function of a woman’s reproductive system is pregnancy and the birth of healthy offspring. In women with menstrual dysfunction in the pubertal period, more than 70% of pregnancy complications are observed, the most common of which are menacing miscarriage and placental insufficiency. Despite the medical and social significance, today there is not enough information about the reproductive potential of women with menstrual dysfunction in the puberty period, and their pregnancy and childbirth.The objective: аccording to laboratory and instrumental methods of research, to study the features of the course of pregnancy in women with menstrual dysfunction in the puberty.Materials and methods. According to the nature of the disorders, the main group of pregnant women (n=120) who had a menstrual pathology in the puberty were divided into 3 subgroups (n=40): the first – pregnant women with primary oligomenorrhea in the anamnesis, the second – with a late age menarche, the third - with puberty bleeding. The control group included pregnant women (n=40) with the correct rhythm of menstruation in puberty.Results. A clinical study found that women with menstrual irregularities in the puberty were significantly more likely than women with the right rhythm of menstruation, pregnancy was complicated by a threatening miscarriage in the early stages, threatening premature birth and chronic placental insufficiency.During the dynamic observation of pregnant women using modern diagnostic examination methods, placental dysfunction in the period of 11–14 weeks was detected in 15,0% of women, chronic placental insufficiency (compensated form) in 30–40 weeks – in 6,7%. At 36–40 weeks, chronic placental insufficiency was diagnosed in 59,2% of women, of which a subcompensated form with growth retardation of the first degree in 8,5% was diagnosed. A histological examination of the placenta revealed chronic placental insufficiency in 62,0% of women, of which 6,5% were in subcompensated form.Conclusion. In the course of a scientific search, an attempt was made to find a confirmation of the assumption that the basis of the genesis of placental dysfunction and related gestational complications in patients with disorders of the formation of menstrual function has a history of hormonal and metabolic imbalance, implantation endometrial insufficiency and vasculogenesis dysfunction, the premises of which are laid on stage of the pathological puberty.The results of the studies indicate the need to improve prognostic and diagnostic methods for the prevention of pregnancy complications in women with menstrual dysfunction in the puberty, based on new knowledge about the mechanisms of their development, and in the current demographic crisis are the requirement of the time.

The work found the shape of spectral lines of electromagnetic radiation produced by a relativistic quantum of magnetic flux moving in a Josephson transmission line under the action of a purely fluctuating external current and dissipation. It is shown that even in the case of a Gaussian noise current, the shape of the spectral lines of electromagnetic radiation has an essentially non-Gaussian form. The limited dispersion of the frequency of electromagnetic radiation (which is determined by the pinching of the spectral lines of radiation) is proved, due to the relativistic properties of the quantum magnetic flux. This is another unique aspect of the relativistic quantum magnetic flux - as a carrier of electromagnetic radiation in the Josephson transmission line.

Accounting information is very essential in the taking of value creation decisions in an organization. Therefore the objective of this study is to identify the relation between the quality of the Accounting Information System and overall Performance within industrial firms. More specifically it builds on the model of Ives, Hamilton and Davis (1980) and Raymond (1984), to propose the conceptual framework of success factors of an accounting information system. The research is an inductive/interpretative research based on the content analysis of five case studies. A conceptual framework of success factors in the light of the model of Raymond (1984) in the Cameroon context is presented based on the analysis of the data suggesting that organizational factors are based on size, the environment and differentiation of information system. While individual factors are based on level of education, leadership style, recruitment etc. Industrial firms should differentiate and integrate their accounting information systems so that they can improve their overall performance. Keywords: Accounting information system, industrial organization, overall performance, differentiation, integration, coordination mechanisms.

A variety of plant and animal resources (waste) can be used as biofuel. The use of biofuel is less profitable than fossil fuels, so many countries introduce special subsidies to encourage their consumption. However, to obtain these subsidies, it is necessary to prove that companies, in case of purchasing imported materials, buy them in countries that support the principles of the current climate agreement. Unlike the United States, which left the Paris climate agreement, Russia has ratified it. This means that European companies have a strong economic interest in purchasing biofuel from Russia, and not from the United States. And Russian timber companies are increased in their motivation for the efficient processing of waste of their main production into a popular export product — fuel pellets and briquettes. However, many timber producers are faced with the problem of choosing a particular type of fuel that is optimally produced in specific production conditions. Keywords: wood waste, biofuel, fuel pellet, fuel briquette.

Published: December 2020

The pandemic of coronavirus disease 2019 (COVID-19) caused by the newly discovered virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), had been noticed to have high morbidity and mortality. Apart from pneumonia, COVID-19 can also cause damage to the cardiovascular system, and co-occurring with cardiovascular injury leads to a poorer prognosis. Besides, amid the pandemic of COVID-19, the management of critical cardiovascular events needs to further account for the highly infectious coronavirus, prompt and optimal treatments, clinician’s safety, and healthcare provider’s capacity. This review article aims to provide more comprehensive and appropriate guidance for the management of critical cardiovascular disease, including ST-segment elevation myocardial infarction (STEMI), non-STEMI acute coronary syndrome, cardiogenic shock, acute heart failure, cardiopulmonary resuscitation, and advanced care planning, during the COVID-19 epidemic.

To investigate the right heart function in coronavirus disease 2019 (COVID-19) patients with acute respiratory distress syndrome (ARDS), a retrospective analysis of 49 COVID-19 patients with ARDS was performed. Patients were divided into severe group and critically-severe group according to the severity of illness. Age-matched healthy volunteers were recruited as a control group. The cardiac cavity diameters, tricuspid annular plane systolic excursion (TAPSE), tricuspid valve regurgitation pressure gradient biggest (TRPG), pulmonary arterial systolic pressure (PASP), maximum inferior vena cava diameter (IVCmax) and minimum diameter (IVCmin), and inferior vena cava collapse index (ICV-CI) were measured using echocardiography. We found that the TAPSE was significantly decreased in pneumonia patients compared to healthy subjects (P < 0.0001), and it was significantly lower in critically-severe patients (P = 0.0068). The TAPSE was less than 17 mm in three (8.6%) severe and five (35.7%) critically-severe patients. In addition, the TAPSE was significantly decreased in severe ARDS patients than in mild ARDS patients. The IVCmax and IVCmin were significantly increased in critically-severe patients compared to healthy subjects and severe patients (P < 0.01), whereas the ICV-CI was significantly decreased (P < 0.05). COVID-19 patients had significantly larger right atrium and ventricle than healthy controls (P < 0.01). The left ventricular ejection fraction (LVEF) in critically-severe patients was significantly lower than that in severe patients and healthy controls (P < 0.05). Right ventricular function was impaired in critically-severe COVID-19 patients. The assessment and protection of the right heart function in COVID-19 patients should be strengthened.

Published: December 2020

Acute kidney injury following cardiac surgery (CS-AKI) represents a severe postoperative complication, negatively impacting short-term and long-term mortality. Due to the lack of a specific treatment, effective prevention remains the most powerful tool to overcome the CS-AKI burden. Improving the preventive strategies is possible by establishing appropriate preoperative risk profiles. Various clinical models were proposed as a means to assist physicians in stratifying the risk of CS-AKI. However, these models are used for predicting severe forms of CS-AKI, while their predictive power for mild forms is insufficient. Our paper represents the first systematic approach to review all proposed preoperative risk factors and their predictive power. Our strategy is the starting point for selecting and comparing the predictive elements to be integrated into future risk models. Heart failure, chronic hyperglycemia, anemia, obesity, preoperative exposure to nephrotoxic drugs or contrast media, inflammation, proteinuria, and pre-existing kidney disease were systematically reviewed and were found to be associated with an increased risk of postoperative CS-AKI. As no externally validated and universally accepted risk models currently exist, the clinical judgment and a good knowledge of the preoperative risk factors in the light of new evidence may help personalize preoperative risk profiles as the cornerstone of prevention measures.

Published: December 2020

Given the trends in the modern world, as well as the rapid growth of digitalization, it is safe to say that it will inevitably affect almost all areas of human life and activities. Dmitriev’s English dictionary defines the word readiness: «It is a state where everything is done to start doing something.» Accordingly, an assessment of the company’s readiness to integrate modern digital technologies will identify opportunities, risks and threats, strengths and weaknesses of the enterprise, as well as to formulate a list of initial measures that need to be implemented. Thus, there is an urgent need to find an answer to the following questions: «How (by, what criteria and indicators) to measure readiness?», «What are the approaches to readiness assessment?» The purpose of this article is to develop a model and algorithm to assess the company’s readiness to integrate modern digital technologies. Modelling techniques were used to achieve this goal, as well as to analyze and generalize information. As a result of the research, a model for assessing the company’s readiness to integrate modern digital technologies has been developed and tested, based on the quality management model presented in the ISO 9000 series standards. A particular example shows how to use it and what it ultimately allows you to see and evaluate.

The quality issues of new services directly affect the competitiveness of service organizations. However, the introduction of new services to the market is often limited only to the construction of the logistics of business processes, and the design applies only to technological equipment and infrastructure, the quality of which ultimately does not always ensure the quality of the services provided. At the same time, quality management affects mainly operational aspects, that is, it covers the later stages of the service life cycle. In resource-intensive service industries (for example, transport, communications, etc.), the high cost of equipment and infrastructure reduces the possibility of changes in service delivery technologies to improve their quality, which leads to inefficiency and market failures due to the fact that the new service does not match the real needs of customers. Despite this, forecasting and planning the quality of a service at the stage «making a decision» to launch a new service on the market remains largely without sufficient attention. The authors prove the need to design the quality of services at the stage «making a decision» to bring new services to the market. The purpose of the article is to describe the approach developed by the authors to assessing the quality of projected services at the early stages of their life cycle, which makes it possible to integrate qualitative and quantitative indicators of the future service and take into account the forecast requests of customers. The proposed approach has two features: (1) forecasting customer requirements for the quality of services is based on the results of machine learning based on data on existing and potential customers, as well as on the basis of the accumulated knowledge base of customer experience and expert opinions; (2) multi-criteria optimization is used, while some of the optimized parameters are discrete and high-quality. In conclusion, the authors demonstrated the advantages of the developed model on the examples of transport and logistics business in the field of passenger and freight transportation in Russia.

The study had provided shows the characteristics of the some surfaces obtained with the electrochemical mechanical processing and describes the common effect of processing modes and its conditions on the surface microrelief. This shaping method is taking an efficiency on finishing operations, which are required both in traditional ways of processing by subtracting the workpiece material, and in an additive technologies. One of the main advantages of an electrochemical machining is the ability at achieving high surface quality and the absence of impacts on the lower layers of the workpiece's surface. The results of surface studies are considered with an example of aluminum, bronze-graphite, iron-graphite, and recommendations are given for improving the surface quality of ductile metal based parts including the materials of the tool blade and its characteristics. The study has focused on the turning, milling and abrasive machining. The greatest relevance of the application of this processing method is associated with the impossibility of obtaining accurate geometric parameters of parts by the most widely used shaping methods at the present, especially for processing parts made of ductile metals and its alloys.

Learning technical genres – a blended learning approach
Authors: Dževerdanović Pejović Milena
Published: December 2020

Research studies dedicated to the application of blended learning in modern linguistics are on the rise. With the interdisciplinary nature of science and curricula, researchers are combining traditional methods with contemporary digital sources and text processing tools. Regardless of the many methods and approaches recommended, there is no set methodology widely proven to be successful, due to different student profiles, language competences and the learning environment. This paper presents the results of the blended learning approach taken at the University of Montenegro’s Faculty of Maritime Studies in Kotor. The traditional teaching approach has been combined with genre and discourse knowledge, with the support of digital and internet tools. The goal of the research is to demonstrate that students of the English for Specific Purposes (ESP) course may benefit from genre- and linguistics-based knowledge applied in the technical and digital environment. Moreover, it is argued that a corpus- and genre-based approach to teaching professional genres provides an opportunity to enrich ESP classes. This approach has primarily proved to be beneficial in teaching technical and engineering genres. Language precision is the essence of effective language competence.

Greece is the dominant force in global shipping and the Greek-owned fleet represents 54,28% of the European Union (EU) fleet in dwt and almost 20% of the world fleet in dwt. Even though there have been many studies for the Greek seafarers, there are no studies for the contribution of the seafarers’ wives to the so-called “Greek shipping miracle”. The purpose of this research is to record and highlight the social profile and the aspects of the daily life of the Greek seafarers’ wives. Furthermore, the research aims to shed light on the attitudes and perceptions of seafarer’s wives towards the seafaring profession. 145 wives of active seafarers, from Chios Island, filled out questionnaires specially made for the purposes of this research. Additionally, 15 in-depth interviews were conducted, in order to analyze and clarify some important findings that were obtained from the completion of the questionnaires.
Perspectives of cruise tourism in the City of Rijeka
Authors: Jugović Alen
Published: December 2020

Purpose – This article discusses a type of activity, level of consumption, and cruise ship tourists’ satisfaction in a destination to understand the perspectives of cruise tourism in the city. Design/Methodology – The research was conducted during 2018 by personal interviews or website questionnaires among 163 cruise tourists in the city of Rijeka, Croatia. The survey included 15 questions that were categorized into five thematic units. The data were processed by descriptive statistics. Findings – According to a slight increase in travelers’ consumption but also their overall satisfaction, the results suggest an increase in destination attractiveness. The economic results are still at a modest level. A set of measures has been proposed to improve tourism services in the destination. Originality of the research – Given those cruise companies are permanently on the lookout for attractive destinations, it is up to cities to attract cruise ships to their ports. It is necessary to assess and check the tourists’ experience of a cruise destination permanently so that the offerings of port city can be adjusted to the changing demands of passengers. Limiting factors associated with cruising point to caution in assessing the future of cruise tourism, especially in a city where this kind of business is just beginning.

Singing behavior via reduced predation risk
Authors: Schruth David , Jordania Joseph
Published: December 2020

A surprisingly diverse array of animals produce sounds with song-like qualities in order to communicate who and where they are to conspecifics when their senses of smell, and in some cases vision, are rendered ineffectual across long or occluded distances. Social factors are typically considered to drive the evolution of such calls, but here we consider broader effects of habitat which are often difficult to observe, measure, and analyze, and are thus typically neglected. We tested the hypothesis that ecological protections from predation enabled animals to call by neutralizing the risk inherent in vocally forfeiting position. We compiled data on human and non-human singing species that live in arboreal, aerial, or aquatic (i.e. non-planar) habitats, to measure the degree to which each presumably helps to reduce predation and thereby allow singing. We find that singing species also forfend predation via larger size as well as increased levels of arboreality and flight. Arboreal primates and birds do appear to sing significantly more so than terrestrial ones. Hunting and warfare in humans, respectively, likewise correlate with the musical features of rhythmic and melodic tension. In all species explored, however, only body size universally correlates positively with singing behavior. We conclude that effects of predation, especially when viewed in a larger, food-web context, play a central role in determining who sings and who does not.
Twenty-Five Years After the ADA: Situating Disability in America’s System of Stratification
Authors: Maroto Michelle Lee , Pettinicchio David
Published: December 2020

Americans with disabilities represent a significant proportion of the population. Despite their numbers and the economic hardships they face, disability is often excluded from general sociological studies of stratification and inequality. To address some of these omissions, this paper focuses on employment and earnings inequality by disability status in the United States since the enactment of the 1990 Americans with Disabilities Act (ADA), a policy that affects many Americans. After using Current Population Survey data from 1988-2014 to describe these continuing disparities, we review research that incorporates multiple theories to explain continuing gaps in employment and earnings by disability status. In addition to theories pointing to the so-called failures of the ADA, explanations also include general criticisms of the capitalist system and economic downturns, dependence on social welfare and disability benefits, the nature of work, and employer attitudes. We conclude with a call for additional research on disability and discrimination that helps to better situate disability within the American stratification system.
Do COVID-19 Lockdown Policies Weaken Civic Attitudes? Survey Evidence from the United States and Europe

The spread of COVID-19 has prompted governments to implement restrictions to public life and the economy (broadly, "lockdown policies''). We evaluate the short- and medium-term impacts of lockdown policies on civic attitudes relevant for the health of democracy. Using survey data collected daily between March and May 2020 in the United States and four European countries from 27,317 respondents and a difference-in-differences design, we document that lockdown policies increase authoritarian values and, to a lesser degree, support for autocracy. We find no effects on satisfaction with democracy and the government, out-group hostility, and generalized trust. Additional analyses reveal that the effects persist for at least seven weeks, that these effects persist after the lifting of lockdowns, and that economic support packages have limited ability to alleviate these effects. We discuss the implications of our findings for how governments might need to accompany lockdowns with measures that strengthen civic culture.
Assessing mortality registration in Kerala: The MARANAM Study
Authors: Gupta Aashish , Mani Sneha
Published: December 2020

Complete or improving civil registration systems in sub-national areas in low- and middle-income countries provide several opportunities to better understand population health and its determinants. In this article, we provide an assessment of vital statistics in Kerala, India. Kerala is home to more than 33 million people and is a comparatively low-mortality context. We use individual-level vital registration data on more than 2.8 million deaths between 2006 and 2017 from the Kerala MARANAM (Mortality and Registration Assessment and Monitoring) Study. Comparing age-specific mortality rates from the Civil Registration System (CRS) to those from the Sample Registration System (SRS), we do not find evidence that the CRS underestimates mortality. Instead, CRS rates are smoother across ages and less variable across periods. In particular, the CRS records higher death rates than the SRS for ages where mortality is usually low and for women. Using these data, we provide the first set of annual sex-specific life tables for any state in India. We find that life expectancy at birth was 77.9 years for women in 2017 and 71.4 years for men. Although Kerala is unique in many ways, our findings strengthen the case for more careful attention to mortality records within low- and middle-income countries, and for their better dissemination by government agencies.
Inefficient Procurement in Times of Pandemia

Published: December 2020

The public health and economic crisis caused by the COVID-19 pandemic has pushed governments to substantially and swiftly increase spending. Consequently, public procurement rules have been relaxed in many places to expedite transactions. However, this may also create opportunities for inefficiency and corruption. Using contract-level information on public spending from Colombia’s e-procurement platform, and a difference-in-differences identification strategy, we find that municipalities classified by a machine learning algorithm as more prone to corruption react to the spending surge by using a larger proportion of discretionary non-competitive contracts and increasing their average value, especially to procure crisis-related items. In these places, contracts signed during the emergency are more likely to have cost overruns, be awarded to campaign donors, and exhibit a range of implementation inefficiencies. Our evidence suggests that large negative shocks such as the recent COVID-19 pandemic may increase waste and corruption.
Burdens, Sludge, Ordeals, Red Tape, Oh My! A User’s Guide to the Study of Frictions
Authors: Madsen Jonas Krogh , Mikkelsen Kim Sass , Moynihan Donald
Published: December 2020

Recent years has seen dramatic growth to the study of frictions that individuals experience, especially in their interactions with the public sector, creating both the potential for new research opportunities and conceptual confusion. We seek to head off the latter by providing, in one place, a definition, description of the development, and comparison of four dominant conceptions of frictions: ordeal mechanisms, red tape, administrative burden, and sludge. In particular, we discuss the four concepts' definition and use in terms of their objectivity, distributive effects, object and domain, and deliberate design. The paper helps researchers to understand the overlap and distinctions between these concepts, and the role of public administration in these different traditions. Comparisons of the different approaches' thinking also suggest opportunities for mutual learning.

With the continued global expansion of COVID-19 transmission and the mounting threat of the disease, the timely analysis of its trend in Nepal and forecasting the potential situation in the country has been deemed necessary. We analyzed the trend, modelling, and impact assessment of COVID-19 cases of Nepal from 23rd January 2020 to 30th April 2020 to portray the scenario of COVID-19 during the first phase of lockdown. Exponential smoothing state-space and autoregressive integrated moving average (ARIMA) models were constructed to forecast the cases. Susceptible-infectious-recovered (SIR) model was fit to estimate the basic reproduction number (Ro) of COVID-19 in Nepal. There has been an increase in the number of cases but the overall growth in COVID-19 was not high. Statistical modelling has shown that COVID-19 cases may continue to increase exponentially in Nepal. The basic reproduction number in Nepal being maintained at a low level of 1.08 for the period of 23rd January to 30th April 2020 is an indication of the effectiveness of lockdown in containing the COVID-19 spread. The models further suggest that COVID-19 might persist until December 2020 with peak cases in August 2020. On the other hand, a basic reproduction number of 1.25 was computed for total cases reported for the 22nd March to 30th April 2020 period implying that COVID-19 may remain for at least a year in the country. Thus, maintaining social distance and stay home policy with an implementation of strict lockdown in the COVID-19 affected district is highly recommended.

Wound healing is a complex process and prevention of wound infection is crucial for wound care as colonization of bacteria delays the healing process. For rapid healing, the wound dressing should have an antibacterial property and biocompatible. Herein, we proposed the use of cinnamon essential oil, a natural antimicrobial agents, incorporated electrospun poly(ɛ-caprolactone) (PCL) fibrous dressings. The wound dressing scaffolds were successfully prepared by electrospinning of the blend solution of poly(ɛ-caprolactone (PCL) with different concentrations of cinnamon essential oil. The mats were characterized by field emission scanning electron microscopy (FESEM), Fourier transform infra-red (FTIR), thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC) analysis. FESEM results revealed that the incorporation of cinnamon oil generated the membrane with fine fibers along with nanofibers compared to uniformly distribute the nanofibers for pristine PCL. Experimental results of cell viability assay and microscopy imaging showed that the as-fabricated composite wound dressing scaffold exhibited excellent cell viability for fibroblast (NIH-3T3) cells. The antimicrobial activity of the composite scaffold was assessed from the zone of inhibition against Gram-positive and Gram-negative bacteria. Results indicated that the fibrous mats inhibited the growth of Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria- Escherichia coli, Salmonella typhimurium, and Pseudomonas aeruginosa showing high antibacterial activity. Overall, our results concluded that the introduced scaffold might be an ideal biomaterial for wound dressing applications.

Published: December 2020

We present a study of the Sloan Digital all Sky Survey Data Release 12 (SDSS DR12) optical spectra of an interacting dwarf galaxy NGC 2604 that has redshift 0.0069. Thirteen characteristic emission lines were identified in the wavelength range of 3885 Å to 6742 Å, the strongest line was due to Hα emission with a value of emission-line flux 1538.8 erg/s/cm2/Å. The other twelve emission lines were observed because of OI doublet, Hβ, Hγ, Hδ, OIII doublet, HeI, SII doublet and NII doublet transitions. Eleven characteristic lines agreed perfectly with the Gaussian distribution with greater than 99.9 % coefficient of regression. However, full-width half maximum (FWHM) was found to be less than 5 Å. No absorption metallic lines were observed in the spectra which indicates that the galaxy was either newly formed. The line metallicity of the galaxy was found to be 8.4 dex and the extinction coefficient was 0.2134. The star formation rate due to Hα emission after extinction correction was found to be 0.0927 Mʘ year -1 which is almost double of the value (0.057 Mʘ year -1) before correction.
