Potassium Levels in COVID Subjects: Current Observations and New Possibilities for its use in COVID Diagnosis
Authors: Padmanabhan Sriram
Published: June 2021

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) causing covid infection in humans is a major global threat to healthcare and economy. According to the recent statistics of the World Health Organization (WHO), the disease has already involved all continents, with almost 117,498,522 cases with more than 2,606,626 deaths all over the globe until March 2021. It is thus, imperative to study and develop pharmacological treatments suitable for the prevention and treatment ofCOVID-19. The COVID causing virus is mainly transmitted through cough or sneeze droplets generated by an infected person. Hence its early and accurate diagnosis appears essential for minimizing spread, prevention and eventually containment of the pandemic. Also, since the clinical presentation of the COVID infection is varied starting from asymptomatic to severe cases, it reinforces the need for detection methods that are simple, early and with good sensitivity and specificity. This article reviews impact of potassium ions in functioning of various organs in humans and its possible role in COVID disease progression.

Published: June 2021

By investigation of movement of the Assur groups in normal connecting condition, and by inspection of the kinematic pair concept, the conclusions were found that “The freedom of Assur group is zero” in the Planar Mechanism Composition Principle conflicts with the fact that Assur group can move, and the external kinematic pairs of Assur group are inconsistent with the kinematic pair concept. Proposals were put forward then that the motion characteristics of Assur group should be studied in normal connecting conditions, Grade I Linkage Group should be introduced, and the PPP Type Linkage Group existence as an example was provided. Some new views were put forward in discussion of Planar Mechanism Composition Principle. And then an example of mechanism analysis was given to show that the correct statement of the Mechanism Composition Principle is helpful to solve mechanism analysis problems.

Zmiana układu sił w stosunkach międzynarodowych: analiza potencjałów z perspektywą do lat 2025−2030
Authors: Smolaga Lech , Smolaga Mateusz
Published: June 2021

This article focuses on the political effects of ongoing shifts in the world economy. Using various indicators, including shares in the global Gross Domestic Product, expenditures on research and development, external balance on goods and services, and military expenditures, the authors present how the positions of major powers in international relations (the United States, the European Union and its countries, Japan, China, and Russia) have changed over the last few decades. Current data and the extrapolation of trends reveal that we are witnessing significant changes in economic power across the world. This has undoubtedly exacerbated existing tensions in international politics. The text tests the hypothesis that a weakening of the major economies of the global North (the US, EU, and Japan), and related shift in the balance of power, are driving the world towards the existence of a multi-polar international system.

Improved Image Denoising Methodology using Deep CNN Bilateral Filter Compared to Additional Methods
Authors: Bora Pallavi , Chaudhary Kapil
Published: June 2021

Image Denoising techniques are widely used to
remove the noise from the images. Due to the ease of the bilateral
filter, it is used very often to remove the noise from the images. In
this paper, a novel approach has been proposed to enhanced
bilateral filter in conjunction with CNN as a booster to eliminate
Gaussian noise from Grey images. Studies reveal that standard
CNN using a bilateral filter is the best technique to eliminate
Gaussian noise from images along with high PSNR values. This
paper also performs a comparative study of the various existing
techniques for image denoising with the CNN technique and the
applied Bilateral filter Method as a de facto to improve the results
in terms of enhanced PSNR values. ECND Net (Enhanced CNN)
applied to noisy images with standard deviation σ = 15 gives
PSNR values up to 32.81 In comparison to this when both
bilateral filter and deep CNN applied, in conjunction produces
improved PSNR values up to 34.73 along with the equivalent
standard deviation. The results in this work reveal better
performance in terms of PSNR as compared to other methods.
The test result proves that the bilateral filter Method along with
CNN can improve the quality of restored images significantly
better.

The data transmission system in the optical WDM network increases the speed of packet transmission by the wavelength of light beams . The Selection of the wavelength and the shortest path to transmit the packets form source to destination is a challenge in a large network architecture. To solve these two problems, the optimization model must handle both the objectives. In this paper we are proposing a novel multi-objective optimization algorithm to solve both the problem of wavelength allocation and shortest path identification in a WDM network. This can be achieved by the enhanced model of Multi-Objective Hunger Locust Optimization algorithm (MO-HLO). In this, it analyse traffic level in a network path and the availability of wavelength present at each time instant. The proposed system retrieves the parameters of network architecture and with the weight value of dynamic traffic occur in the routing path. Among these data, the optimization selects the best among overall feature set of the WDM arrangement. The MO-HLO algorithm extracts the combination of each attribute to form the cluster that segregates the routing path along with the traffic range. From the fitness of the objective function of MO-HLO, the best routing path and the availability of wavelength for a node can be analysed at each time instant.
Moss as Bio-indicator for Air Quality Monitoring at Different Air Quality Environment
Authors: Yatim Nurulshyha Md , Azman Nur Izzatul Afifah
Published: June 2021

Air quality monitoring by using bio-indicator
currently being promoted and frequently used in studies due to
their advantages compared to other scientific approaches. The
advantages of using bio-indicator as a bio-monitoring in air
quality are, it remains the cheapest, most available and simplest
matrix for reliable atmospheric monitoring. This study was
conducted to determine moss ability to be used as a bio-indicator
for air quality monitoring when expose to different air quality
environments. Four environmental conditions were chosen to
conduct this study; urban area, reserve forest, living room and
smoker’s room. Leucobryum glaucum or Holland moss is used as
the bio-indicator to monitor the air quality. Gridded containers of
moss were left at each study location for the duration of two
weeks. Physical observation was monitored weekly by examining
colour changes of the moss. Survivability rate of the moss was
determined by counting the numbers of grid where moss growth in
each container. The data was recorded through physical
observation of moss responses and survivability rate towards
different air quality environment. The data was analyzed by using
SPSS. Moss reacted accordingly towards different air quality
environments. Moss reacts mostly at highly polluted environment,
in smoker’s room by changing from fresh green to brownish in
color. In conclusion, moss can be used as a bio-indicator in air
quality monitoring to determine air quality condition because
moss changes its physical appearance and growth rate by the
influenced of surrounding environment.
Adsorption Kinetics of Malachite Green Dye Removal from Aqueous Solution by using
Banana Stem
Authors: Kumar K Arun , S, Sandeep.
Published: June 2021

This research work goals at searching the
effectiveness of Malachite Green dye removal using banana stem,
an agricultural waste as an activated carbon. The banana stem
activated carbon was made ready in the laboratory by
carbonization followed by activation. Adsorption studies were
carried out to check the effect of various experimental conditions
like different pH values, varying contact time, initial
concentration of dye and changing banana stem carbon dosage
on the removal of Malachite Green dye from aqueous solution at
constant Temperature and agitation speed. The equilibrium
experimental data were used for applicability of Langmuir and
Freundlich isotherm models and the kinetic models. Batch test
showed that maximum of 99% of dye was removed when the dye
concentration was 2 mg/L, at an adsorbent dose of 0.75 gm/L at
dye pH 8 in 45 minutes. From the obtained results it is validated
that the equilibrium data’s favorable for both Freundlich and
Langmuir isotherms. Maximum adsorption capacity of banana
stem carbon on malachite green dye was found to be 8.29 mg/g. It
was prevailing that the adsorption process followed the
pseudo-second-order rate kinetics. It was observed that intra
particle diffusion is not the only rate-limiting step in this
adsorption system but also regression results indicate that the
linear regression model gives the best results. The above
observations recommend that Banana stem carbon can be
competently implemented for removal of malachite green dye from
aqueous solution in the adsorption treatment processes.
Development measures for slums of Dhaka city
Authors: Ahmed Sinthia Sanjida
Published: June 2021

Dhaka, the capital city of Bangladesh is extremely populated, unhygienic and environmentally degraded city. The growing number of population and environmental degradation are due to natural disaster and economic depression. As a result, the rate of urban poor is and producing huge pressure on urban lands, housing and infrastructure. Due to limited resources these poor people encroached open spaces, wetlands, vacant plots or even footpath for shelter. They don’t have any access to proper job market, healthcare facilities, education and sanitation either. These constraints are mostly resulted from the failures of the government in initiation proper policies and measures. Past policies of slum clearance, modernist apartment projects, housing provision, self-help, sites and services, and in-situ upgrading have not been effective at solving the crisis. This is now prime time to established planning and environmental management policy and sustainable development of the city area. Urban land management, rehabilitation and socio-economic development of the slum dwellers are also very important issues. The key focus of this paper is to find out sustainable development process for urban slum dwellers and build sustainable living place for them which are free from eviction, criminals, rent seekers and other miscreants.
PATTERNS AND CORRELATES OF DECENTRALISATION IN PRIVATE NIGERIAN ENTERPRISES
Authors: Inegbenebor A. U.
Published: June 2021

The ability of private Nigerian entrepreneurs to initiate and institutionalise effective organisational structures and processes needed to carry out complex industrial activities is crucial to the realisation of the objective of rapid, selfreliant, industrial development of Nigeria. This study examined the patterns and correlates of a key structural variable in the organisational process — decentralisation of decision-making authority. The study was based on a sample of forty-one manufacturing enterprises in the Midwestern Zone of Nigeria which were wholly owned by private Nigerian entrepreneurs. The results indicate that decentralisation of decision making was generally limited. Participation of the Board of Directors was restricted. There was marked variation in decentralisation in the functional areas with finance function as the least decentralised and production/operations function as the most decentralised. The response to the contingencies of size and technology was considered appropriate while the response to competition was contrary to expectation. Apart from this, the nature of decentralisation in the enterprises was in the direction generally found in more advanced economics.
Critical Failure Mechanisms in Isolated Three-phase Multilevel Inverters Design
Authors: Iglesias-Rojas Juan Carlos
Published: June 2021

Isolated multilevel inverters are widely used in renewable energy systems and industrial applications. Isolated IGBT topologies exploit the usage of low-frequency transformers that improve robustness and reliability. However, critical failure mechanisms should be considered at the design stage to ensure proper performance. This paper describes these critical failure mechanisms, such as short circuit, cross-conduction, IGBT high inductive load avalanche, IGBT second turn-on, VS-undershoot, transformer inrush current, IGBT thermal runaway, and cable switching interference. Furthermore, this paper comprises design techniques to prevent these failures. The previous failure mechanisms come from the inverter's power stage, except switching interference from control signal cables and directly affecting the control device functionality. This work also proposes a circuit topology based on FPGA resources to reduce switching interference from control signal cables. It behaves like a fault tolerant digital input that effectively filters bouncing events shorter than 2μs. Measurements report satisfactory experimental results upon constructing a 45kVA ac-side-isolated 13-level inverter.

O diabetes é uma doença caracterizada por distúrbios metabólicos que resultam na elevação da glicose no sangue, de forma que pacientes diabéticos necessitam de cuidados a fim de controlar os níveis de glicemia. Uma das consequências dessa patologia é o surgimento do pé diabético, que se traduz em problemas circulatórios, neurológicos e ortopédicos. Outras intercorrências podem aparecer, como as úlceras arteriais e venosas, as quais, se não tratadas, têm significativa chance de evoluírem e levarem à amputação do membro inferior afetado. Os podólogos auxiliam a medicina na prevenção de problemas relacionados aos pés e são, portanto, os profissionais de saúde capacitados aos cuidados dessas ulcerações. Além de atuarem de modo preventivo na orientação de pacientes, eles também desenvolvem um trabalho de acompanhamento e higienização. A profilaxia realizada por um podólogo é a melhor medida para o não surgimento de lesões nos pés e, na iminência dessas, caberá orientar o paciente de modo a não extensão do trauma.

ДЕТЕРМИНАНТЫ ФОРМИРОВАНИЯ ГЛОБАЛЬНОЙ ИНКЛЮЗИВНОЙ ЦИРКУЛЯРНОЙ ЭКОНОМИКИ
Authors: Юсупова М.Д.
Published: June 2021

Транзитивный путь перехода с линейной к циркулярной экономике сказывается изменением позиционирования глобальных рисков. Так, основными рисками на 2020 г. определены риски, связанные с окружающей средой, которые занимают первые позиции в рейтинге в течение трех последних лет (в 2019 г. самым влиятельным был риск экстремальных погодных явлений). Постепенный рост осознания этого риска привел к изменению видения как производителей, так и потребителей. Эксперты оценили изменение климата как основной риск 2019 г. Таким образом, для смягчения данного риска мировым бизнес-сообществом предложено имплементировать циркулярные «конструкции», уменьшая использование ресурсов и предоставляя приоритет низкоуглеродистым материалам. Потенциальные положительные последствия перехода к циркулярной экономике в отношении выбросов парниковых газов значительны, и достичь их можно главным образом за счет повышения эффективности использования ресурсов, увеличения срока полезного использования основных средств, увеличения переработки и повторного использования сырья.

Published: June 2021

Background: As one of the vulnerable groups to be infected by COVID-19, healthcare workers are required to obey the hospital rules and protocols. However, it may remain challenging for them, especially related to the provision of using personal protective equipment.Objective: This study examined the obedience of medical personnel to personal protective equipment in preventing the transmission of COVID-19 at PKU Muhammadiyah Hospital Yogyakarta, Indonesia.Methods: This cross-sectional study examined 259 medical personnel (medical doctors, nurses, and midwives) in the hospital. Descriptive statistics, Chi-Square test, and multiple logistic regression were used for data analysis.Results: The majority of respondents were nurses (80.3%) and female (63.3%). Those who had a poor attitude would be three times more likely to have poor obedience to using personal protective equipment (Adj. OR: 2.81, 95% CI: 1.52 - 5.19). Sex, age, length of work, level of knowledge, level of motivation, and facility support were not correlated with obedience to using personal protective equipment.Conclusion: The finding reported that many medical personnel were not obedient to using personal protective equipment because their response to disease prevention was poor. The results can be used for further intervention and education or training programs for medical personnel.

Authors: Pisaniak Paulina , Żołądź Joanna , Tarczoń Aleksander , Ozga Dorota
Published: June 2021

Aim: Stigmatization is about making a division – people are grouped into better and worse, people with mental disorders are very often perceived as different, which is why they are largely stigmatized. Mental illnesses are a growing problem among the society of developed countries, therefore, the problem of stigmatization of these people has also become noticeable, which may adversely affect their mental condition and the convalescence process. The aim of the study is to assess the degree of stigmatization of mentally ill people by paramedics.
Material and methods: An original questionnaire was used to collect the data, distributed from February 15, 2020 to April 7, 2020. among paramedics working in various medical rescue units and in units cooperating with the National Medical Rescue system. We collected 91 respondents replied. The research was a pilot study.
Results: Paramedics are a professional group that does not show any particular signs of stigmatization in relation to the mentally ill, but single responses were obtained, which may indicate a given respondent’s lack of understanding for the mentally ill.
Conclusions: In order to prevent stigmatization of the mentally ill, it is very important to educate not only paramedics, but also representatives of other medical professions who have contact with people suffering from mental disorders.

Results: Methods of direct contrasting of the biliary tract make it possible to visualize choledocholithiasis with 86.5% accuracy, with 84.1% common bile duct strictures, with 87.8% stricture of biliodigestive anastomosis and with 97.5% accuracy of cholangiocarcinomas.
Conclusions: Direct antegrade bile duct enhancement should be used if ERCPG has low explanatory value. PTCG in case of “endoscopically complicated forms” of choledocholithiasis, CBD and BDA strictures and cholangiocarcinomas enhances all bile duct sections and helps assess the level and completeness of biliary blockade. Following PTCG, measures can be taken to achieve biliary decompression regardless of OJ genesis.

Aim: To study the formation of pathological brain systems and their transformation during treatment in patients with acute and chronic cerebral ischemia, using the method of quantitative EEG with wavelet analysis. Material and methods: In the period from 2016 to 2020, 120 people aged 40 to 68 years with CSI and IS were comprehensively examined in dynamics. Patients underwent quantitative EEG (qEEG) with wavelet analysis on days 1, 7, 14, 21, 28. In addition to the protocol, one group of patients received ethylmethyhydropyridoxine succinate. Results: The formation of a new system with a decrease or disappearance of the dominant frequency in the delta range, the appearance of a dominant frequency in the theta range and a subdominant frequency in the alpha range indicates the restoration of brain function. The applied course of neurometabolic therapy leads to such a change in the EEG wavelet graphs after 3-4 weeks in 86.6% of patients. And in the control group, similar changes occur during this period only in 53.3% of patients. Conclusions: To assess the effectiveness of treatment of acute and chronic cerebral ischemia, it is advisable to use a complex of amplitude-time representation of an EEG signal using continuous wavelet transform. The effectiveness of neuromethobolic therapy aimed at eliminating mitochondrial dysfunction can be assessed using the method of quantitative EEG with wavelet transformation, to study the formation and destruction of stable pathological brain systems in patients with cerebral ischemia.

Встановлені в процесі досліджень закономірності показують, що коефіцієнти морозостійкості асфальтобетонів різною мірою знижуються під впливом циклічних заморожувань-відтавань. Дана робота дозволяє рекомендувати використання додаткових коефіцієнтів запасу морозостійкості при проектуванні нових автомобільних доріг з шарами нежорсткого дорожнього одягу. Для визначення необхідного показника запасу морозостійкості  розглянуто дорожню конструкцію з ВБН В.2.3-218-186-2004 «Дорожній одяг нежорсткого типу». З цієї конструкції взято модулі пружності асфальтобетонів верхніх шарів та розраховано зміну коефіцієнтів запасу міцності з урахуванням зміни модулів під дією циклічних заморожувань-відтавань.

Великопролітні просторові конструктивні системи найчастіше застосовуються в будівлях та спорудах, де одночасно перебуває велика кількість людей, тому їх проектування, зведення та експлуатація вимагає постійного вдосконалення. Одним із шляхів вирішення цієї проблеми є пошук надійних природних аналогів і їх використання в просторових конструктивних системах.
The Solution Ways of the Agricultural Problems in Samtskhe-Javakheti Region
Authors: Kenchoshvili Mariam Kenchoshvili Mariam
Published: June 2021

In Georgia agriculture faces many challenges though there are few beneficial movements in this sector. As the article mainly describes the challenges of potato production development, the statistical data analysis will be useful. In 2008-2019 local potato supply rate was increased from 86% up to 93% in the country, especially in the condition when the potato land plots reduced from 24 thousand to 16.4 thousand ha, while the quantity of the produced potato has been increased unequally. Rural farms, regardless they are domestic or commercial are still flexible on the market against the prices of other agricultural product, this was the reason why the total potato land plots used to increase or reduce. In many cases the reason for reduction of the plots is the problems with harvest sales and low prices compared to primary cost of the product due to which the cultivated land plots were reduced. In addition, 99% produce potato.
The majority of Samtskhe-Javakheti residents was and is engaged before and now in the agriculture actively. The region population is actively involved in both crop production and livestock breeding. The speed of production volume changing in the agriculture gives us possibility to base regional development concept on agricultural development in combination with the processing industry. For the recent years the size of the state funding of the sector is permanently increasing, though there are many indicators showing that it is early to talk about quality improvement of the field.
Additionally, the article discusses the steps made towards development of agriculture and there are stipulations about the reasons of their ineffectiveness. The solution ways and directions are also suggested for overcoming the causes on the example of Samtskhe-Javakheti region. By considering the fact that potato production is the major direction of the crop production in Samtskhe-Javakheti, the discussion mainly focuses on existing situation in potato growing of the region, analyzing the situation, threats and opportunities, strengths and weaknesses.
In Summary, we have developed the model for the region in order to have a precedent for overcoming the challenges in the potato production, which will show the rural household and enterprises how it is possible to reflect supporting policy of the state on the financial results of the activities. The model does not require great financial expenses, though it can be an important stimulus for other domestic farms and the example for the regional cooperatives developed on the model, supporting to development agriculture and entire region together processing industry.

Every business company is profit-oriented. The scale of profit is determined by the effectiveness of the activity, the quality of service provided to customers, speed of service, simplicity and all of the above -is the result of ongoing business-processes in the company. The forced stagnation can occur at any stage of the project development, however, even if it is not so, after a certain period, there always comes a moment, when changes in the work process are inevitable.
The prerequisite for the proper writing of business-processes is a thorough knowledge of the ongoing processes in the company and the existence of relevant qualified staff. Because if any link is dropped or misspelled during the business-process cycle, the whole business-process will be wrong and the result will inevitably affect the company's efficiency.
The Business-Process optimization has become vital for modern companies, especially in the age of digital technologies. The companies face the new challenges every day, and the modern technologies allow them to achieve their goals easily and at a much lower human or material costs.

The Liner services provides regular shipments of goods between ports within the set timeframe. A fixed route, the obligation of receiving cargo and to go to sea with established schedule distinguishes line service from the sea transportation of bulk cargo.
Containerization, establishment and improvement of routes and infrastructure helped liner shipping to become the driving force of Global economy, which supports the growth of international trade, development of different business forms such as mainly small and medium sized businesses.
The shipment volume of containerized cargo was 37.1 M.TEU in 1994, by 2020 the figure reached up to 143.3 M.TEU. This indicator was growing at a high rate on East-West route during 1990-2016; In terms of North-South, South-South and intraregional route same measure was high between 1990-2004 years. Afterwards, Abovementioned growth has become more stable.
Containerization changed the structure of Liner fleet. If general cargo vessels deadweight was growing during 1970-2010 (From 40.5M Dwt to 99.7M Dwt), in the latest 10 years, the tonnage has been decreasing and as for 2020 it was 74.6M Dwt. In exchange for this the number of container ships have been growing consistently and in 2020 it consisted of 274.7M Dwt.
Maersk became the largest line operator since 2001 (with a market share of 9.4%) and by 2020 it’s share of the business has grown to 17%. The company owns container terminals worldwide, including the Poti container terminal. MSC is on second place (9.4% market share), COSCO is on third place (12.4%) and CMA CGM takes forth place (11.8%).

The title of the article - "Development of Georgia's Trade Relations with Ukraine" shows Georgia's trade relations with Ukraine. According to the information presented in the article, which is spread over the years 2016-2020, in this 5-year period, the total trade turnover and export-import are increasing, which does not apply to the last 2020. This year, all the above indicators have been reduced - turnover by 9%, exports - by 13%, imports - by 6%. The author connects this situation with the cooling of diplomatic relations between the two countries. Because of Saakashvili's personality and emphasizes that this situation has improved today.
Georgia has a special close economic and economic ties with Ukraine among the countries of the world. This applies not only to the export-import of goods, but also to tourist traffic, investment, employment, etc. Sh. This relationship was established in 1995 with the conclusion of the Free Trade Agreement [1].
One of the characteristic features of foreign trade between Ukraine and Georgia is the fact that Georgia's share in the total foreign trade of Ukrainian goods is insignificant (about 0.5%), while Ukraine's share in Georgia's total trade turnover reaches 5.1%. According to the results of January-September 2020, among all Georgia's trading partners, Ukraine ranks 7th in terms of trade turnover, 5th in terms of exports of goods and 8th in terms of imports of goods. Georgia-Ukraine turnover in 2020 compared to 2019 has decreased - by 9%, exports - by 13%, imports - by 6% (Table 1). Under these conditions, there is an increase in some goods, in particular, an increase in imports:
 Beef - by 43%;
 Copton – by 17%;
 Milk and cream – by 29%;
 Flat rolled- by 10%.
As for exports from Georgia to Ukraine, the export of ferroalloys (17 times) and the export of scrap (6 times) have increased.
