12. Evaluation of Optimal Storage and Transport Medium for the Detection of Group B Streptococcus in StrepB Carrot Broth
Authors: Trotman Grant A. , Bard Dien , Raney J.
Published: April 2021

Group B streptococcus (GBS) is the leading infectious cause of morbidity and mortality among newborns in the USA and optimal detection of GBS colonization in pregnant women is paramount. In 2010, the Centers for Disease Control and Prevention (CDC) revised consensus guidelines for the prevention of GBS disease to include identification by chromogenic media such as StrepB Carrot Broth (CB). However, limited data are available to determine the optimal storage and transport medium (TM) required to optimize GBS survival. We compared ESwab and Amies TM to recover GBS in CB for up to 144 h at 4oC, 21oC and 24oC. 50 isolates of GBS from vaginorectal swabs were evaluated. 100 μL aliquots of 103 CFU/mL suspensions were inoculated onto Amies and ESwab TM and stored at the evaluated times and temperatures. At 24 h time periods, Amies and ESwab TM were inoculated into CB and incubated for 24 h. Results were quantified as 0, 1+, 2+, 3+, and 4+ with the degree of pigmentation correlating with the recovery of GBS. ESwab was superior to Amies at all temperatures but was optimal at 21ºC and 24ºC, whereas recovery in Amies was significantly decreased at these temperatures. Results support the use of CB to facilitate detection of GBS. Furthermore, this demonstrates that ESwab TM is superior to Amies TM for recovery of GBS, particularly when stored at 21ºC and 24ºC. In light of these findings, the CDC may consider expanding the recommendations to include alternate transport systems in addition to non-nutritive medium.

Published: April 2021

DOI 10.24917/20837275.9.4.1Artykuł porusza problem metodologiczny topografii krajobrazu filmowego. Dla podejścia tego równie ważne co dyskurs wizualny, zorientowany na tryb analizy estetycznej są praktyki kulturowe, pozwalające w procesach filmowego postrzegania i przetwarzania krajobrazów dostrzegać elementy życia i doświadczenia. Zasadniczą tezą jest stwierdzenie, że do filmowejeksploracji krajobrazu i miejsca daje się zastosować praktyka wizualnego mapowania. Mapowanie w filmie rozumiane jest jako sposób myślenia, zarówno twórcy (reżysera, operatora), jak i odbiorcy dzieła (widza), który wiąże się z przyjęciem przez nich pewnego punktu widzenia oraz zastosowaniem/odkrywaniem określonej taktyki. Wśród strategii mapowania wyróżnione i omówione zostały, za Teresą Castro: chorografia (opis), topofilia (miłość do miejsca) i penetracja.Topography of a film landscapeThe paper raises the issue of the methodological problem of topography of a film landscape. For this approach are equally important – the visual discourse oriented on an aesthetic analysis mode and the cultural practices enabling to recognize the elements of life and experience in the processes of film perception and transformation of landscapes. The fundamental thesis is the statement that it is possible to use the practice of visual mapping to explore a landscape and place. The mapping in a film is understood as at the same time a way of thinking of a creator (director, operator) and a recipient of a work (a viewer), which is connected with adopting by them certain point of view and the application/ discovering of a specific tactics. Among the strategies of mapping, according to Teresa Castro, there were distinguished the following: chorography (description), topophilia (love of place) and surveying.

Case report: early onset narcolepsy initially misdiagnosed as obstructive sleep apnea syndrome
Authors: Almbaidheen Mahmut , Bodur Muhittin
Published: April 2021

Background. Narcolepsy is a chronic neurological syndrome, which is characterized by excessive sleepiness, cataplexy, hypnagogic hallucinations, and sleep paralysis during the rapid eye movement period of sleep. This disease is commonly diagnosed within adulthood. However, the first symptoms often appear in childhood and/or adolescence. Pediatric cases of narcolepsy generally remain unrecognized and undiagnosed. Clinical heterogeneity, prolonged onset and diverse symptoms contribute to the delay in diagnosis and treatment in childhood.
Case. This report describes a case of narcolepsy in an 8,5-year-old male patient who was misdiagnosed as obstructive sleep apnea syndrome and many other diagnoses at different hospitals over a period of 3 years before the correct diagnosis was made.
Conclusions. Narcolepsy in children is a rare neurological syndrome, which can occur with uncommon and atypical clinical presentations. In our case report we aimed to highlight pediatric narcolepsy, which could help to make more appropriate approaches and prevent misdiagnoses or diagnosis delay in these cases.

Crude oil price prediction using CEEMDAN and LSTM-attention with news sentiment index
Authors: Hu Zhenda
Published: April 2021

Crude oil is one of the most powerful types of energy and the fluctuation of its price influences the global economy. Therefore, building a scientific model to accurately predict the price of crude oil is significant for investors, governments and researchers. However, the nonlinearity and nonstationarity of crude oil prices make it a challenging task for forecasting time series accurately. To handle the issue, this paper proposed a novel forecasting approach for crude oil prices that combines Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN), Long Short-Term Memory (LSTM) with attention mechanism and addition, following the well-known “decomposition and ensemble” framework. In addition, a news sentiment index based on Chinese crude oil news texts was constructed and added to the prediction of crude oil prices. And we made full use of attention mechanism to better integrate price series and sentiment series according to the characteristics of each component. To validate the performance of the proposed CEEMDAN-LSTM_att-ADD, we selected the Mean Absolute Percent Error (MAPE), the Root Mean Squared Error (RMSE) and the Diebold-Mariano (DM) statistic as evaluation criterias. Abundant experiments were conducted on West Texas Intermediate (WTI) spot crude oil prices. The proposed approach outperformed several state-of-the-art methods for forecasting crude oil prices, which proved the effectiveness of the CEEMDAN-LSTM_att-ADD with the news sentiment index.

Published: April 2021

ABSTRACT – This article examines the objective and quantifiable data conversion in visual and syncretic discursive forms aimed at mobilizing experiences of the conveyed senses. In addition to making the invisible visible, what is proposed here is to make the unspeakable visible by analyzing the overdetermination of the effect of intensity, proximity, and presence on news content. To achieve this goal this paper uses empirical data obtained from infographics printed in The New York Times (NYT) and Folha de S.Paulo newspapers on the covid-19 pandemic. This was chosen because the objective data in numbers and figures affect how true opinion is shaped and the infographics were recurrently employed (during our research period) by all media as an effective mechanism for understanding the facts. The empirical methodology is anchored in the perspective of tension semiotics that provides theoretical foundations for studying the sensitive dimension of interactional processes.RESUMO – Propõe-se neste artigo examinar o processo de conversão de dados, considerados objetivos e quantificáveis, em formas discursivas visuais e sincréticas voltadas a mobilizar experienciações dos sentidos veiculados.

Authors: Krishtal M. I. , Shchekoturov A. V.
Published: April 2021

Social networks increasingly act as a full-fledged tool in the process of expressing one’s identity and self- presentation. The object of this study was the cross-platform self-presentation of Russian students in three different social networks: «VKontakte», «Facebook» and «Instagram». The authors consider cross-platformness in the article refers as the ability to simultaneously construct the desired impression in various Internet platforms, taking into account the specifics of their functionality and audience. The subject of the study is the motives and characteristics of cross-platform self-presentation in these social networks. The research method is in-depth interviews with students of Immanuel Kant Baltic Federal University (Kaliningrad, Russia). The paper carries out narrative analysis in a special software package Atlas.ti. The authors pay particular attention to the motivations for using social networks, as well as the similarities and differences in the pictures and content published on different virtual platforms. The main conclusion of this study is that social media users prefer different forms of self-presentations. The authors found that the nature of self-presentation is related both to the motives for using social networks and their technological capabilities. On Facebook, the prerequisite for the formation of self-presentation is the ability to communicate with a more serious and adult audience. In «VKontakte» – to be part of a community consisting mostly of close friends and peers. In «Instagram» – the visual perception of a person by a person. Along with this, the specificity of self-presentation is also affected by the different functionality of social networks. In particular, «Instagram» provides the most effective opportunities for account users to show events from their lives.
Political leaders and young people: interaction in social networks
Authors: Komarova A. A.
Published: April 2021

In modern Russian society, there is a deep gap between political activity and active political communication with young people, bringing information to this target audience. Political leaders are the force that is able to convey to people values and guidelines, the meaning of life, to show the way to the future, to lead for the implementation of the necessary changes in the social, political, and economic life of society. However, the established methods of communication are not effective, as a generation has grown up with different social ideas about political leaders and other communication needs. This article is devoted to the study of the interaction of political leaders with young people through the mass media at the current stage of development of Russian society. The paper considers the theoretical foundations of the research of the youth audience. As a result of a comprehensive study, the author revealed the awareness of young people about current politicians. The article takes as a basis the names of politicians from the top 100 most influential politicians in Russia, according to the Agency for Political and Economic Communications. The first part of the research is devoted to the study of the value orientations of modern youth. The paper reveals the problems in communication between modern politicians and young people, investigates the information channels used by young people to receive current political news. The most important source of political information for the youth audience is the Internet and social networks. This is due to the increasing role of social networks in the global communication processes in general, as well as the involvement of the youth audience in the media consumption of social network content. Young people see the greatest communication problems in the status and financial gap between current politicians and youth groups, as well as the difference in value orientations and the age barrier. For a comparative analysis of the data, the sample was divided according to the criteria of age (respondents were divided into three age groups) and gender.

Процессы самоорганизации в водном растворе L-цистеина, нитрата серебра, карбоксиметилцеллюлозы (КМЦ) и сульфата натрия исследованы с использованием методов вискозиметрии и УФ спектроскопии. Установлено, что водный раствор на основе L-цистеина и нитрата серебра (цистеин-серебряный раствор - ЦСР) хорошо совместим с водным раствором КМЦ, образуя при этом прозрачный гидрогель без введения электролита-инициатора. Рост концентрации КМЦ в растворе и дополнительное введение электролита (сульфат натрия) приводило к увеличению вязкости получаемых гидрогелей.

Self-organization processes in an aqueous solution of L-cysteine, silver nitrate, carboxymethyl cellulose (CMC), and sodium sulfate were studied using viscometry and UV spectroscopy methods. It was found that an aqueous solution based on L-cysteine and silver nitrate (cysteine-silver solution - CSS) is well compatible with an aqueous solution of CMC, thus forming a transparent hydrogel without introducing an initiator electrolyte. An increase in the concentration of CMC in solution and an additional introduction of an electrolyte (sodium sulfate) led to an increase in the viscosity of the resulting hydrogels.
THE IDENTIFICATION OF CENTRAL JAVA CLASSIC ERA’S ARCHITECTURE (BOROBUDUR AND PRAMBANAN, (9TH CENTURY) ON THE TEMPLE IN THE CAMBODIA’S TRASITIONAL ERA (BAKONG, 9TH CENTURY) MORPHOLOGICAL TYPOLOGY STUDIES (MASS ORGANIZATION, FLOOR PLAN, FIGURE AND ORNAMENTS)
Authors: Pratomo ; Rahadhian Prajudi Herwindo Galih Andika
Published: April 2021

Abstract- Architectural temples of the middle classical era such as Prambanan and Borobudur temples are thought to have inspired the temples in Indochina. It has become a common guess both among the tour guides in Cambodia or the researchers who reviewed the Khemer Kingdom Architecture. The existence of the relationship between the temple in Java and the temple in Cambodia is possible because Jayawarman II, who later build the kingdom of Khemer, once lived in Java when large middle classical temple style architecture was built. To find out the architectural connections of temples in Java and in Cambodia then the first thing to do is to know all the architectural unsurts in both temples. So the purpose of this study is to know the unsurts of spatial, plan, figures and temple ornaments of the middle classical era of Java and pre-Angkor temple era. This research is done by qualitative method of comparative. Qualitative research is applied by visiting and observing physical objects, then discussed using theories relating to research topics. While the object is selected using purposive sampling method, with the basic object of research is closely related to the style, wholeness and scale. Of the 80 points used in identifying architectural unsurts in the mass structure, floor plan, figures, and ornaments, the authors found 13 very similar points, 50 points to Bakong but not similar, and 17 points missing from Bakong. Based on these results the allegation that the temple of the middle classical era of Java has a relationship with the transitional era are becoming stronger. Key Words: morphology, architectural elements, Borobudur, Prambanan, Bakong

Abstract- In the early stage of the scenario realization has been done improvements in the alun alun area, also Jl. Jend. Sudirman. In the year 2016 carried out revitalization pedestrian paths on block Jl. Jend. Sudirman. Revitalization of pedestrian paths is preferred because pedestrian paths are the most basic public spaces to facilitate the movement of pedestrians from one place to another. However, the activity on this relatively new pedestrian path affects other names with existing building frontages.By qualitative method, this research read the pattern of dissemination of activity and condition of frontage of building on research object. This is done to determine whether the frontage of buildings and activities in the outer space have a relationship with each other. From this study found that the activity is not only influenced by the nature and material frontage of the building, but there is also a typology of space formed by the frontage of the building. Typology of space is closely related to the activities that occur in outer space.                 Key Words: Frontage, Active Frontage, City Furniture, Building Functions, Activities, Outer Space.
Anti-inflammatory activity of raw and processed stingless bee honey
Authors: Chong K.Y. , Chin N.L. , Yusof Y.A. , Fakurazi S.
Published: April 2021

The anti-inflammatory activity of raw and processed Kelulut stingless bee honey was
investigated for its ability to inhibit nitric oxide (NO) production in lipopolysaccharidestimulated RAW 264.7 cells. Raw honey was optimally processed by thermal processing
and thermosonication at 90°C. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium
bromide (MTT) cell viability assay showed that Kelulut honey from 7.8 to 500 µg/mL was
not cytotoxic to RAW 264.7 cells as it resulted in at least 80% viable cells after 24 hr.
Both raw and processed honey from 10 to 300 µg/mL displayed an increase and decrease
in NO concentrations, suggesting a mixed effect of NO inhibition and enhancement.
Maximum NO inhibition of 17.5% was recorded from 20 µg/mL of thermally processed
honey while the highest NO enhancement of 7.8% was from 10 µg/mL of
thermosonicated honey. The NO effects were independent of honey concentration and
processing techniques, suggesting its potential robustness in medicinal properties as part
of the diet.

Moisture sorption characteristic is important in determining the stability of bio-based
plastic during packaging and storage condition. This study was carried out to investigate
the moisture sorption characteristic of starch-based film. Moisture sorption test was
conducted at different temperatures (5, 30 and 50°C) and relative humidity (23-75%). The
experimental data was fitted using several models. Based on the Peleg model, the
maximum rate of absorption and absorption capacity occurred at higher relative humidity.
Guggenheim Anderson de Boer (GAB) model was the most suitable model to fit the
experimental isotherm data and it is useful to predict the water sorption properties of the
film which relate to different relative humidity conditions. In addition, the shelf life of
film was reduced when placed under lower temperature due to the higher sorption
capacity of moisture. The sorption properties of the starch-based film are important and
worth investigation as it will be useful for the final application in food packaging due to
its dependency on this behaviour.

Authors: Cherkasova V. A. , Slepushenko G. A.
Published: April 2021

Digitalization is one of the most urgent problems for Russia; companies need to gain a competitive advantage, increase their efficiency and improve business performance. The aim of the study is to identify the relationship between the financial performance of Russian companies and the degree of digitalization of their business processes. Operating profit was chosen as the main financial indicator reflecting the results of the current core activities of the companies. To calculate the digitalization index, McKinsey information data was taken on six parameters: digital marketing, digital product experience, e-commerce, electronic customer relationship management (E-CRM), social networks. The authors used regression analysis of data from 482 companies from 20 industries for the period 2017–2019 as a research method for testing the hypotheses. The findings of the study revealed that the digitalization index has a positive effect on the operational efficiency of companies, but the degree of influence differs depending on the industry, age, and size of the enterprise. The authors concluded that the greatest effect from digitalization is observed among companies with traditionally high digital maturity. These are companies from the financial, technology, or communications industry, where business digitalization is vital and where a slowdown in digital transformation processes can push such enterprises far back in the ranking. Assessing the impact of digitalization of Russian companies on their operational activities will allow the management of companies to choose the right strategy in matters of digital transformation, which will ensure the company’s competitiveness, increase its efficiency and contribute to its development. On a national scale, the results of this study can help decide which industries should be subsidized for digital innovation.

Published: April 2021

Distributed data storage technologies are becoming an integral part of the modern economy. In this regard, today it is veryrelevantto a search for formalized approaches to assessing the impact of blockchain technologies on key parameters of macroeconomic generations. Thesubjectof the research is the system of relations between economic entities of the national economy, associated with the perception of blockchain technologies that permeate economic processes. Theaimof the study is to develop a methodological toolkit for scenario forecasting of possible consequences for the national economy of the introduction of blockchain technologies into the economic sector. The authors applymethodsof cointegration analysis, scenario modeling, substantiation of the studied patterns by methods of regression analysis, etc. The authors use works of foreign and Russian scientists, official data of the Federal State Statistics Service of the Russian Federation as an information and statistical database. The authors systematize positive and negative externalities; propose an algorithm for studying the influence of blockchain technologies on the dynamics of GDP through the transformation of the key parameters of the functioning of the financial and real sectors of the economy; build a model and assess the possible impact on GDP of the integration of blockchain technologies into the economy. As a result, the authors make the followingconclusions: to the greatest extent, the integration of blockchain technologies into the business processes of the national economy affects the change in the financial results of credit institutions, an increase in capital liquidity of economic agents, as well as the acceleration of the processes of socialization of channels of access of business entities to financial markets (expanding access of economic agents to exchanges). Scenario modeling of changes in these factors made it possible to establish that the potential for additional GDP growth in the Russian economy can reach about 1% per year as part of the integration of distributed data storage technologies into the system of economic relations. The developed and approved methods for the formalized assessment of the impact of blockchain technologies on the dynamics of economic growth create the basis for clarifying methodological approaches to the study of the problem posed, open up new opportunities for holding discussion platforms on this topic.

Published: April 2021

The article aims to analyze the external and internal growth factors of the People’s Republic of China in 2010–2017. The authors use methods such as input-output modeling, statistical methods, content analysis of scientific publications. The study explores different perspectives on China’s rapid economic growth in recent decades. In particular, the authors consider neoclassical models that investigate and explain the dynamics of the Chinese economy due to the accumulation and development of factors of domestic production. Some studies are analyzed, which consider economic growth as a result of the final demand, both internal and external, on the basis of the input-output approach. The article examines the views that interpret the monetary policy as one of the most important factors in stimulating economic growth. The authors, based on the economic growth decomposition method, determine the components due to domestic demand and the components due to exports, both for the entire Chinese economy and for particular industries. Сalculations based on the data of input-output balances for 2010–2017 allowed the authors to draw a conclusion about the significant contribution of domestic demand to the economic growth of China in the context of active monetary stimulus. Thus, the novelty of the study is ensured by the fact that Thirlwall’s law does not apply to modern China –– stimulating the economy in China does not lead to a decrease in the trade surplus due to the monetary and financial sovereignty, industrial competitiveness, and the innovative economic development. The search for tools for adapting China’s monetary policy to the realities of Russia and the Republic of Belarus opens up opportunities for future research on the topic.
Problems of Financial Investigation and Recovery of stolen Assets
Authors: Zemskov V. V. , Prasolov V. I.
Published: April 2021

In the context of the globalization of national economies, the processes of recovering stolen assets are becoming a difficult task, requiring their tracing and detection not only in our country but also in foreign jurisdictions. Not only country’s law enforcement agencies but also corporate governance bodies should play an active role in the process of detecting and recovering stolen assets. In this regard, the improvement of methodological tools that facilitate the tracking, detection and recovery of stolen assets is of scientific and practical interest and ensures the relevance of the study. The purpose of the study is to improve the mechanisms for countering the withdrawal of assets by unscrupulous owners, interest groups. The authors apply methods of dialectical scientific cognition based on a set of recognized private scientific and general scientific methods: formal-logical, comparative-legal, statistical, intersectoral legal analysis. The scientific novelty of the research is the identification of negative factors affecting the volume of stolen assets, their impact on the economic health of the state, private sector, and the improvement of methods for detecting and recovering assets. The results of the study help the authors to identify the main problems of detection and recovery of stolen assets, formulated the directions of the strategy for the return of stolen assets, formalized the processes of tax administration in countering the legalization of illegally obtained property. The recovery of stolen assets is an extremely time-consuming process which requires not only collective action of government agencies but also effective interstate cooperation within the legal framework. The paper presents a comparative analysis of the legislation of a number of countries. The authors identify deficiencies in the Russian law, which does not fully prescribe the procedure for detecting and returning stolen assets to the territory of the country. The authors conclude that in order to improve the mechanisms for countering the withdrawal of assets, it is necessary to apply an integrated approach, improving the legislation of the Russian Federation and fostering collective action of the country’s law enforcement agencies, private sector, and society to successfully confront new challenges and threats. The results of the study may be used to improve the competence of law enforcement officers involved in detecting and returning stolen assets, as well as to develop a more successful methodological and evidence base approach in countering the legalization of illegally obtained property.

Authors: Stroev P. V. , Milchakov M. V. , Pivovarova O. V.
Published: April 2021

The authors investigate the prospects for the spatial development of modern Russia highlighting the supporting regions considered in the budgetary aspect. The relevance of the study is due to the insufficient evidence for the effectiveness of the current policy of “equalization”, as well as the need for breakthrough growth of the Russian economy within the framework of national development goals. The present paper aims to identify one of the key elements of the supporting framework of the spatial organization of Russia in terms of the level of fiscal capacity. The research methodology is based on the use of complex, statistical and comparative analyses. The authors used official data of Rosstat on the population, tax and non-tax revenues, gratuitous receipts in 2010 and 2019 by regions of Russia. The authors highlight the key aspects of the spatial development of the Russian economy in the regional context: human capital development, economic development, the functioning of spatial structures of various types, fiscal capacity, environmental component, location of information and communication infrastructure, and geopolitical position. The influence of the fiscal capacity parameter on the sustainable socio-economic development of the region is justified. The fiscal capacity index of the constituent entities of Russia is analyzed at the end of 2010 and 2019, the main trends are identified. The study presents a cartographic visualization of the Russian regions by per capita fiscal capacity for tax and non-tax revenues of the consolidated budgets in 2019. The authors carried out a comparative analysis of the revenues of consolidated regional budgets on the macro-regional level, as a result of which the leading regions were identified and their budget parameters described.The present paper outlines one of the key elements of the supporting framework of Russian spatial organization from the point of view of fiscal capacity and identifies potential regions supporting spatial development in the context of macro-regions. The authors conclude that the supporting framework of the spatial organization of Russia, formed by the level of fiscal capacity, characterizes the financial potential of the territories, which can contribute to the development of interregional cooperation, including through the use of mechanisms for ensuring “horizontal” inter-budgetary transfers and budget loans. The prospect for further research on this topic consists in assessing and shaping other elements of the spatial development of Russia and identifying, by uniting them, supporting regions that can stimulate the development of not only the semi-periphery and periphery of their macro-regions but also of the entire country.
