Damping analysis to improve the performance of shunt capacitive RF MEMS switch
Authors: Thalluri Lakshmi , Kumar K.V.V. , Sekhar Konari , Babu Bhushana , Kiran S.S. , Guha Koushik
Published: December 2021

This paper describes the significance of the iterative approach and the
structure damping analysis which help to get better the performance and
validation of shunt capacitive RF MEMS switch. The micro-cantilever based
electrostatic ally actuated shunt capacitive RF MEMS switch is designed and
after multiple iterations on cantilever structure a modification of the
structure is obtained that requires low actuation voltage of 7.3 V for 3 ?m
deformation. To validate the structure we have performed the damping
analysis for each iteration. The low actuation voltage is a consequence of
identifying the critical membrane thickness of 0.7 ?m, and incorporating two
slots and holes into the membrane. The holes to the membrane help in stress
distribution. We performed the Eigen frequency analysis of the membrane. The
RF MEMS switch is micro machined on a CPW transmission line with Gap-
Strip-Gap (G-S-G) of 85 ?m - 70 ?m - 85 ?m. The switch RF isolation
properties are analyzed with high dielectric constant thin films i.e., AlN,
GaAs, and HfO2. For all the dielectric thin films the RF MEMS switch shows a
high isolation of -63.2 dB, but there is shift in the radio frequency.
Because of presence of the holes in the membrane the switch exhibits a very
low insertion loss of -0.12 dB.

Authors: Bag Biplab , Biswas Sushanta , Sarkar Partha
Published: December 2021

In this paper dual wideband high gain circular shaped microstrip antenna with
modified ground plane is presented for wireless communication systems. The
overall dimension of the proposed antenna is 50 x 40 x 1.6 mm3. The
radiating element consists of circular shaped patch which is excited by
microstrip feed-line printed on FR4 epoxy substrate. The ground plane is on
the other side of the substrate having a rectangular ring shape to enhance
the peak gain of the antenna. The proposed antenna exhibits two wide
fractional bandwidths (based on ? -10 dB) of 61.1% (ranging from 2.0 to 3.8
GHz, centred at 2.88 GHz) and 53.37% (ranging from 5.48 to 9.6 GHz, centred
at 7.44 GHz). The measured peak gain achieved is 8.25 dBi at 8.76 GHz. The
measured impedance bandwidth and gain suffice all the commercial bands of
wireless systems such as 4G LTE band-40, Bluetooth, Wi-Fi, WLAN, WiMAX,
C-band, and Xband. The measured results are experimentally tested and
verified with simulated results. A reasonable agreement is found between
them.

Published: December 2021

using cloud computing develops, one of the problems that managers face at
the organization level is that the personnel cannot work with these systems,
users do not accept these new systems and the problem of accepting these
technologies, effective factors in accepting them and the existing barriers
in accepting them by users are very important. In many organizations wherein
cloud computing has been launched, a time period is required to accept this
new system by their personnel. If this time period is less and the personnel
can work with these systems earlier, the productivity increases in the
organization. The present paper aims the analysis of effective factors on
acceptance of cloud computing by personnel working in Birjand International
Airport in South Khorasan County (Iran) based on Roger?s diffusion of
innovation theory. Examination of effective factors on acceptance of cloud
computing in an organization can pave the way for improving its
implementation and performance. This research has been done by descriptive
survey method and its community includes personnel working in different
official and informatics departments of Birjand International Airport. The
data gathering instrument was questionnaire and for determining
questionnaire validity opinions of masters and for determining consistency
Cronbach's alpha has been used. For data analysis descriptive and
inferential statistics have been used. The results of present paper
indicated that there is meaningful and positive relationship between
acceptance features of cloud computing and perception elements of
testability, comparative advantage, visibility, complexity, and
compatibility of cloud computing with its acceptance rate and there is
meaningful and negative relationship between features of perception of not
needing cloud computing and its acceptance rate. But there was no meaningful
relationship between perception of cloud computing test opportunity and its
acceptance rate. As one of the modern ways of providing electronic service
has been cloud computing in recent years and it has many benefits for air
transportation systems, this paper presents a model for analysis of
effective factors in acceptance of cloud computing among personnel of an
airline company (airport) and it can be used for examining cloud acceptance
in other air companies.
SARS-COV-2: Rise and fall of the Croatian scenario. An ethnography of the corona-politics in the Croatian pandemic crisis management
Authors: Prica Ines
Published: December 2021

The oscillations in the Croatian scenario of the struggle with the pandemic
are followed by the considerable rearrangements of the key social actors.
The initial success in the controle of the disease, as well as goverment
measures for the rescue of national economy (recognized as the return of
social state), have led to the unprecedentent public suppport and hope in
the renowal of the disturbed social cohesion. The optimism was projected in
the unexpected cognitive collectivity awaken by trust in the credible and
expert management of the crisis, clear of political manipulations.
Nevertheless, the divergence in both political and professional judgements
of the coming changes of epidemiological measures, aimed to balance the
public health and the social-economic risks, have led to the unexpected
realignments of the social-critical stances, especially concerning the
cultural understanding of labour economic relations, marked by the conflict
of the public and private sector.
The pandemic: A breeding ground for authoritarian power grabs
Authors: Zaric Zona , Mladenovic Ivica
Published: December 2021

This article attempts to demonstrate that the COVID-19 pandemic provided
possibilities for numerous (non)democratic governments to impose new
restrictions on civil liberties, persecute opponents, limit protests and
introduce new mass surveillance techniques, thus turning a devastating
biological virus into a damaging political virus that has markedly eroded
the overall state of freedom in the world in just a few months. In countries
considered non-democratic, but also in so-called democratic ones, the
restriction of freedoms is justified in the name of preservation of mere
biological life (zo?). This new historical event unveils the fact that the
crisis has not been handled using democratic means, even in democratic
states, but rather by means they have in common with all states, including
the most authoritarian ones: by using tracking technologies, without any due
process or control by intermediary bodies, by taking decisions by a few, and
by using the urgency of the situation in order to be granted excessive
powers. Using the interpretive framework of Michel Foucault, Gilles Deleuze
and Giorgo Agamben, we illustrate the new direction of late capitalism and
the dormant political effects of handling the health crisis.
Together alone: Opportunities and limitations of mature coresidency during the COVID-19 pandemic
Authors: Mitrovic Katarina
Published: December 2021

The subject of this paper are cultural representations of disease, care and
dependence in households of the so-called ?mature coresidency?. This concept
refers to families in which parents live with their adult children and
focuses on the phenomenon of ?extended youth? - longer transition to
adulthood, economic and residential dependence of young people in the
parental home. The life of young people with their parents, in research and
narratives, is often perceived as a forced, conditioned by the political and
economic situation in the country. Having in mind the circumstances under
which the situation with the COVID-19 pandemic developed and changed, from
months of fear and panic to formal closure in the form of quarantine, I
discuss family dynamics, division of labor, and possible changes in the
roles of family members responsible for household maintenance, grocery
shopping etc. Furthermore, I analyze whether the attitude towards living
together has changed in the situation of the COVID-19 pandemic, by examining
how interlocutors interpret their own roles, obligations within the
household and care for its members. The aim of this paper is to review the
opportunities and limitations of family cohabitation while examining whether
young people and their parents perceive coresidency during the pandemic as a
positive and strategic, or a negative and dangerous circumstance. Moreover,
it will be discussed if young people, perceived as a risk in public sphere,
are also perceived as a risk within their own households. The paper relies
on the results of a qualitative research conducted in Belgrade since April
2020 among young adults their parents.
“To go crazy, to snap and that's it…” coronavirus pandemic and nursing homes in Croatia
Authors: Vukusic Ana-Marija
Published: December 2021

Starting from the assumption that the COVID-19 pandemic has had the strongest
impact on social groups that were already vulnerable and marginalized, and
underlined existing social inequalities, I focus on some of the consequences
of pandemic control measures on the daily lives of elderly people. In the
first part of the paper, I deal with the ?positioning? of elderly people in
the context of COVID-19 protection measures - which, following the
recommendations of the World Health Organization, were adopted by individual
countries - discussing the features of ageism that can be read from them.
Later I focus on the characteristics of protection measures in nursing homes
in Croatia and, using as material media articles that thematize the lives of
the people in these institutions, indicate some of the consequences of a
strict prevention regime on the lives of these people, their mental and
physical health but also some of the fundamental human rights, such as
dignity, freedom, and equality.

Published: December 2021

Low-cost decorated sodium alginate beads with polyaniline (Alg@PANI beads) were easily prepared using a cross-linking method, and employed for the adsorption of Cr(VI) from aqueous solutions. The effect of several influencing parameters, including temperature, contact time, Cr(VI) concentration, and adsorbent dosage, was investigated and optimized using central composite design (CCD) under response surface methodology (RSM). The analysis of variance (ANOVA) of the quadratic model and the analyzed model revealed that the models were statistically significant, with a low P-value (<0.0001) and a high correlation coefficient value (R2 = 0.93). The optimum parameters for total adsorption were as follows: adsorbent dose 0.027 g, pH 2, contact time 45 min, temperature 38?C, and Cr(VI) concentration 29.24 ppm. The findings of this study indicate that the prepared Alg@PANI beads could be effectively used to remove Cr(VI) ions from aqueous solutions.

Pancreastatin (PST), a chromogranin A–derived potent physiological dysglycemic peptide, regulates glucose/insulin homeostasis. We have identified a nonsynonymous functional PST variant (p.Gly297Ser; rs9658664) that occurs in a large section of human populations. Association analysis of this single nucleotide polymorphism with cardiovascular/metabolic disease states in Indian populations (n = 4,300 subjects) displays elevated plasma glucose, glycosylated hemoglobin, diastolic blood pressure, and catecholamines in Gly/Ser subjects as compared with wild-type individuals (Gly/Gly). Consistently, the 297Ser allele confers an increased risk (∼1.3–1.6-fold) for type 2 diabetes/hypertension/coronary artery disease/metabolic syndrome. In corroboration, the variant peptide (PST-297S) displays gain-of-potency in several cellular events relevant for cardiometabolic disorders (e.g., increased expression of gluconeogenic genes, increased catecholamine secretion, and greater inhibition of insulin-stimulated glucose uptake) than the wild-type peptide. Computational docking analysis and molecular dynamics simulations show higher affinity binding of PST-297S peptide with glucose-regulated protein 78 (GRP78) and insulin receptor than the wild-type peptide, providing a mechanistic basis for the enhanced activity of the variant peptide. In vitro binding assays validate these in silico predictions of PST peptides binding to GRP78 and insulin receptor. In conclusion, the PST 297Ser allele influences cardiovascular/metabolic phenotypes and emerges as a novel risk factor for type 2 diabetes/hypertension/coronary artery disease in human populations.

Most genome-wide association studies (GWAS) of complex traits are performed using models with additive allelic effects. Hundreds of loci associated with type 2 diabetes have been identified using this approach. Additive models, however, can miss loci with recessive effects, thereby leaving potentially important genes undiscovered. We conducted the largest GWAS meta-analysis using a recessive model for type 2 diabetes. Our discovery sample included 33,139 case subjects and 279,507 control subjects from 7 European-ancestry cohorts, including the UK Biobank. We identified 51 loci associated with type 2 diabetes, including five variants undetected by prior additive analyses. Two of the five variants had minor allele frequency of <5% and were each associated with more than a doubled risk in homozygous carriers. Using two additional cohorts, FinnGen and a Danish cohort, we replicated three of the variants, including one of the low-frequency variants, rs115018790, which had an odds ratio in homozygous carriers of 2.56 (95% CI 2.05–3.19; P = 1 × 10−16) and a stronger effect in men than in women (for interaction, P = 7 × 10−7). The signal was associated with multiple diabetes-related traits, with homozygous carriers showing a 10% decrease in LDL cholesterol and a 20% increase in triglycerides; colocalization analysis linked this signal to reduced expression of the nearby PELO gene. These results demonstrate that recessive models, when compared with GWAS using the additive approach, can identify novel loci, including large-effect variants with pathophysiological consequences relevant to type 2 diabetes.
Cobalamin Intake and Related Biomarkers: Examining Associations With Mortality Risk Among Adults With Type 2 Diabetes in NHANES
Authors: Wang Shanjie , Wang Ye , Wan Xin , Guo Junchen , Zhang Yiying , Tian Maoyi , Fang Shaohong , Yu Bo
Published: December 2021

OBJECTIVE

Despite that periodical monitoring of cobalamin (vitamin B12) in metformin-treated patients with diabetes is recommended, cobalamin-associated mortality benefits or risks remain unclear. We investigated the association between cobalamin intake and related biomarkers and mortality risk in adults with diabetes using metformin or not.

RESEARCH DESIGN AND METHODS

This study included 3,277 adults with type 2 diabetes from the National Health and Nutrition Examination Survey (NHANES) and followed up until 31 December 2015. Weighted Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% CIs for mortality risk.

RESULTS

Among 3,277 participants, 865 all-cause deaths occurred during a median follow-up of 7.02 years. There was no robust relationship between all-cause mortality and serum cobalamin or intake of foods or cobalamin supplements, regardless of metformin treatment (each P ≥ 0.120). The doubling of methylmalonic acid (MMA), a cobalamin-deficiency marker, was significantly associated with higher all-cause (HR 1.31 [95% CI 1.18–1.45], P < 0.001) and cardiac (HR 1.38 [95% CI 1.14–1.67], P = 0.001) mortality. Cobalamin sensitivity was assessed by the combination of binary B12low/high and MMAlow/high (cutoff values: cobalamin 400 pg/mL, MMA 250 nmol/L). Patients with decreased cobalamin sensitivity (MMAhighB12high) had the highest mortality risk. The multivariable-adjusted HRs (95% CIs) of all-cause mortality in MMAlowB12low, MMAlowB12high, MMAhighB12low, and MMAhighB12high groups were 1.00 (reference), 0.98 (0.75–1.28), 1.49 (1.16–1.92), and 1.96 (1.38–2.78), respectively. That association was especially significant in metformin nonusers.

CONCLUSIONS

Serum and dietary cobalamin were not associated with reduced mortality. Decreased cobalamin sensitivity was significantly associated with all-cause and cardiac mortality, particularly among metformin nonusers.

KiddyCAT- ja BigCAT -itsearviointilomakkeiden suomennosten normatiiviset ja psykometriset ominaisuudet
Authors: Jansson-Verkasalo Eira , Lindblad Siiri , Vastamäki Essi , Eggers Kurt , Vanryckeghem Martine
Published: December 2021

Lasten kommunikointiasenteita arvioivan “Communication Attitude Test for Preschool and Kindergarten Children Who Stutter” (KiddyCAT) ja aikuisten kommunikointiasenteita arvioivan “Communication Attitude Test for Adults” (BigCAT) -testien kansainvälinen tutkimus on osoittanut, että änkyttävät lapset ja aikuiset suhtautuvat kielteisemmin puhumiseen kuin sujuvasti puhuvat verrokit. Tämän tutkimuksen tavoitteena oli arvioida KiddyCAT-Fin- ja BigCAT-Fin-testien suomennosten pätevyyttä (validiteettia) ja luotettavuutta (reliabiliteettia). Lisäksi tavoitteena oli määritellä kummallekin testille kliinisen käytön tueksi katkaisupistemäärä, jonka ylittävä pistemäärä ilmaisee keskimääräistä kielteisempää kommunikointiasennetta. Tutkimuksessa 86 alle kouluikäistä lasta (joista 41 änkyttävää) täytti KiddyCAT-Fin:n 12 kysymystä sisältävän itsearviointilomakkeen ja 109 aikuista (joista 29 änkyttävää) täytti BigCAT-Fin:n 34 kysymystä sisältävän itsearviointilomakkeen. Itsearviointien kokonaispistemäärien keskiarvot olivat lähellä alkuperäisten englanninkielisten versioiden arvoja. Lisäksi änkyttävien lasten ja aikuisten kommunikointiasenteet olivat merkitsevästi kielteisemmät kuin sujuvasti puhuvien. Kummankin testin sisäinen konsistenssi ja uudelleenmittausreliabiliteetti olivat korkeat. Suomennettujen KiddyCAT:n ja BigCAT:n voidaan todeta erottelevan änkyttävien ihmisten kommunikointiasenteet tehokkaasti sujuvasti puhuvien ihmisten asenteista
Toimijuus ja vuorovaikutusjärjestys amerikkalaisten suomenoppijoiden itsenäisessä kielenkäytössä
Authors: Räsänen Elisa
Published: December 2021

Aiemmat tutkimukset ovat osoittaneet vastakkainasettelun luokassa ja luokan ulkopuolella tapahtuvassa kielenkäytössä ja oppimisessa. Tässä artikkelissa tarkastelen neljää amerikkalaista suomenoppijaa ja sitä, miten he hakeutuvat aktiivisina toimijoina itsenäisiin suomen kielen käyttötilanteisiin. Artikkelin aineistona on portfoliotehtävä, jossa oppijat ovat dokumentoineet ja reflektoineet itsenäistä, luokkahuoneen ulkopuolella tapahtuvaa kielenkäyttöään. Tarkastelen aineistoa Scollonin ja Scollonin (2004) neksusanalyysia ja van Lierin (2010) ekologista viitekehystä hyödyntäen. Artikkelin analyysimenetelmänä on diskurssianalyysi. Portfolioissa dokumentoidut vuorovaikutustilanteet rakentuivat hierarkkisesti, mikä usein syntyi oppijan pyrkimyksestä saada vuorovaikutuskumppanista ja -tilanteesta maksimaalinen hyöty ja kielellinen altistus. Lisäksi hierarkkisuutta loivat oppijan ja asiantuntevan suomenpuhujan erilaisiksi koetut roolit. Vuorovaikutus rakentuikin usein oppijan aloitteen ja asiantuntevan kielenkäyttäjän vastausten varaan. Tämä artikkeli osoittaa, kuinka suuri merkitys aloitteellisuudella, toimintaympäristöllä ja vuorovaikutuskumppaneilla on vieraan kielen oppijoiden itsenäisessä kielenkäytössä. Tutkimustuloksia voi hyödyntää vieraan kielen pedagogiikan kehittämiseen, jotta se vastaisi paremmin oppijoiden todellisia kielenkäyttötarpeita.
Ambient Air Pollution and Mortality Rate in Nigeria: An ARDL Approach
Authors: Amos Nuhu Sunday , Adofu Ilemona
Published: December 2021

The study on ambient air pollution and mortality rate in Nigeria is an attempt to evaluate the effect of ambient air pollution proxied by carbon dioxide on non-accidental, cardiovascular and respiratory disease related mortality in Nigeria from 1970-2019. Time series data adopted from World Development Indicators were analyzed using Auto Regressive Distributed Lag Model. Results suggest a positive relationship between CO2 and crude death rate in Nigeria. Thus, the result of ARDL for lnCruder as the dependent variable showed that carbon dioxide emission was positively related to the crude death rate. Consequently, one unit increase in the quantity of carbon dioxide emission increased the death rate by 19% at lag 1, all things being equal. A similar result was obtained for CO2 and life expectancy where carbon dioxide emission was found to have a negative effect on life expectancy. The study concludes that carbon dioxide emission has a negative effect on human health and causes death in human beings. Therefore, further study is recommended on ways of abating carbon dioxide emissions through the use of technologies that generate less carbon dioxide and the adoption of domestic practices that reduce the quantity of CO2 produced in the environment.
Post COVID-19 and the Potential of Blended Learning in Higher Institutions: Exploring Students and Lecturers Perspectives on Learning Outcomes in Blended Learning
Authors: Ntim Stephen , Opoku-Manu Michael , Addai-Amoah Kwarteng Anthony
Published: December 2021

This study explored students and teachers of Higher Educational Institutions perspectives on the potential of Blended Learning post-Covid-19. Using Shea’s 2007 Four-Model of Blended Learning and the framework of Complex Adaptive Blended Learning (BL) Systems, this paper investigated the correlation between Blended Learning (BL) and students learning outcomes in constructivists learning. The findings provided convincing support that Online Blended Learning offers some potential for teaching in higher institutions more than the stand-alone traditional face-to-face classroom. This is especially the case when teaching intends to enhance students reciprocal learning, students’ inquiry-based learning, learners posing questions and seeking answers on their own, as well as promoting cooperative/collaborative learning among students. Even though, the findings did not entirely dismiss the traditional face-to-face teaching, nevertheless, the results strongly suggest that blending face-to-face teaching with online teaching offers tremendous potential for inquiry-based and constructivist learning more than the traditional classroom face-to-face teaching alone. Additionally, BL creates both cohesive and effective learning environment overcoming geographical and physical barriers of traditional classroom teaching to promote self-paced critical learning among students, especially in institutions of higher learning.
Active Listening as A Basic Skill of Efficient Communication Between Teachers and Parents: An Empirical Study
Authors: Chatzinikola Maria E.
Published: December 2021

This study deals with active listening as a basic skill of efficient communication used by teachers in their communication with their students’ parents. Two hundred and twenty-two teachers and thirty-three principals of primary education school units participated in this empirical study. Teachers mention that they use active listening in their communication with parents with attention and observation, they accept parents’ words, they maintain a neutral position and they show empathy to share their reflections and feelings. Moreover, during the use of active listening as an active skill of efficient communication between teachers and parents, teachers mention the contribution of their verbal intervention. In this way they ask open-ended and closed-ended questions for clarifications, and they repeat the parent’s main views without expressing their personal opinion. During their verbal positioning, teachers first mention to parents the good characteristics of their children, then they focus on their learning weaknesses.

This paper looks at Science taught in Ghana generally. It defines Science and science education fundamentally, as the methodical observation, conception, analysis, and exhibition of patterns to understand what exist in the physical universe which is evidence-based and their interactions with each other. The understanding of these processes keeps changing as new relationships and explanations emerge. The motion and interactivity with materials employed by the pedagogies become key elements for creating exciting, dynamic and captivating experiences that motivate students to learn and pursue a science course with a greater sense of purpose. Science education is the teaching and learning of science to non-scientists, such as school children, college students, or adults within the general public. The field of science education includes work in science content, science process, some social science, and some teaching pedagogy. However, the employ of inappropriate teaching methodologies is one of the factors that contribute to the low participation and performance of students in science. Little effort is made to relate the concepts learnt and the examples/illustrations used to real life, especially within the context of the students' own lives and environment. This article attempts to proffer a concise definition to merge the ideas from some scholars for a better understanding of science; meaning of Science Education; relevance of the study of science (or science education); problems of science teaching in Ghana and the effects and propounds a challenging model for implementation for effective science teaching in Colleges of Education in Ghana.
Highly Effective Learning and Application Thereof to Roma Pupils Elementary Education System in Slovakia
Authors: Pankevič Michal
Published: December 2021

Fragmentation of educational content, caused by the scientific-subject structure of the traditional school, in many cases inhibits the motivation and activity of pupils in the educational process. The saturation of knowledge, skills, and competencies— especially of roma pupils in elementary education—is thus underestimated and in many cases lags behind the standard level of the majority of pupils. It follows that the effectiveness of elementary education—especially for roma pupils—increases proportionally with the relevancy and a certain attractiveness of teaching organizational forms and methods whereby it is implemented. One of the alternative solutions for increasing the level of effectiveness of elementary education (inter alia) of roma pupils is the pedagogical concept of highly effective learning based on an integrated thematic teaching system. It turns out that in this context this concept can be considered as a motivating and activating element expanding the knowledge level of pupils, while at the same time enriching them educationally. It integrates strategies that are focused on the discovery, action, cooperative, authentic, and confluent learning of pupils. This paper deals with the issue of the educational concept of highly effective learning in terms of its application to roma pupils in the first grade of elementary education. It presents the current results of a pedagogical experiment as the elementary empirical method of research in the field of social climate, creativity, and the level of knowledge of pupils within the elementary first-grade educational environment.

The Features of the Reference Frame Concomitant to the Cosmic Microwave Background
Authors: Svishch V. M.
Published: December 2021

The features of reference frame, concomitant to the cosmic microwave background, immobile relatively cosmic microwave background, are considered. It is shown that the features of reference frame, concomitant to the cosmic microwave background (CMB), are determined by its properties. Any other object in the Universe and reference frame concomitant to it, is immersed in the CMB and moves relative to the reference frame concomitant to microwave background radiation. The zero pecular velocity of the reference frame concomitant to the microwave background radiation is analogous to the zero temperature on the Kelvin scale. Time in it is most rapid in relation to the time in any other reference frame, observable and measurable in any of them. The features of time, pecular speed, relative speed of two inertial RF, stellar aberration, and Doppler effect in the reference frame concomitant to the microwave background radiation are considered. According to the determined relative velocity of the two reference systems and the peculiar velocity of the reference system with the observer, the components of their relative velocity are determined. Determining the components of the relative velocity of the reference frames with determining the synchronous time for all points at any time in the reference frame concomitant to microwave background radiation, allows us to investigate the possibility of determining the speed of light "one way" and using it to navigate vehicles in distant space. Stability of angular location of heterogeneities of CMB in reference frame concomitant to CMB, allows us to use these heterogeneities for the increase of exactness of astronomic reference frames HCRF and ICRF.

Published: December 2021

Die Aufgaben im Projektmanagement werden weiter an Bedeutung gewinnen, Angebot und Nachfrage nach Zertifizierungen im Projektmanagement sind groß und nehmen zu. Daher stellt sich die Frage, welchen Wert und welchen Nutzen Zertifizierungen im Projektmanagement haben. Dazu wurden über 3.600 nach IPMA zertifizierte Projektmitarbeiter/innen in Deutschland befragt. Ermittelt werden die Motive, welche die Befragten dazu bringen, ein Zertifikat im Projektmanagement anzustreben. Diese Motive werden verglichen mit dem Wert und dem Nutzen, die Jahre später tatsächlich wahrgenommen werden. Im Ergebnis leisten die Motivbündel „persönliche Herausforderung“, „fachliche Weiterentwicklung“ und „berufliches Weiterkommen“ deutliche Beiträge zur Motivation, eine Zertifizierung im Projektmanagement anzustreben. Insgesamt weisen die Befragten ihren Zertifikaten erheblichen Wert bei und halten ihr Engagement und ihren Aufwand für eine Zertifizierung für lohnenswert. Über 80 % der Befragten sprechen eine Empfehlung für das Erlangen eines Zertifikats im Projektmanagement aus.

HISTORICAL AND MODERN ASPECTS OF TREATMENT OF LOWER LIMB VARICOSE VEIN DISEASE (THE LITERATURE REVIEW)
Authors: Gumenchuk Oleksandr , Shevchenko Olena , Kobzar Oleksandr
Published: December 2021

In developed countries, lower limb varicose vein (LLVV) is determined in 25% of the adult population. The high prevalence of varicose vein disease and the likelihood of severe complications developments determine the socio- economic importance of ﬁ nding the eﬀ ective methods of treatment this pathology. Age, height, female gender, overweight and heredity are well known traditional risk factors. The pathogenesis of LLVV is a complex and multifactorial process.The aﬀ ected of endothelial cells is the main pathogenetic link in the LLVV development, that leads to a violation of their antithrombogenic properties. In the future, other membranes of the vein wall are involved in the pathological process. The development of LLVV is associated with a violation of the venous valves and their damage as well. The main method for diagnostic LLVV is ultrasound CT angiogram, that allows you to simultaneously visualize the researched vessel, determine the direction of blood ﬂ ow and its parameters, its individual anatomical features. There are conservative and surgical methods of LLVV treatment. The ﬁ rst attempts of the conservative management for this disease were wrapping the aﬀ ected leg, as evidenced by the rock paintings that had been found in the Sahara Desert. The current analogue is the compression therapy, which plays a major role in the conservative management of venous diseases. Before the conservative method of treatment of LLVV the drug therapy is used as well. The use of various herbs for the management of blood vessels was common in ancient India. Currently, there is the wide range of modern pleotropic drugs. Aulus Cornelius Celsus removed varicose veins with a tiny hook, which is an extremely early version of a varicose vein treatment performed today. In the following centuries, the methods of surgical treatment of this disease were constantly have been improved. Nowadays, the most frequently used methods of varicose vein obliteration are based on endovasal thermal damage of the venous wall, that leads to the occlusive ﬁ brosis and transformation of the vein into a connective tissue cord. The main advantages of these interventions are minimal trauma, speedy rehabilitation, and good cosmetic result.

Research methods. The methods of analysis, synthesis, comparison, generalization are used in research. Scientific novelty. Today, economic issues cannot be considered in isolation without the problems of the industrial sector. We now understand that industrialization is the primary factor in creating an independent and developed domestic market for each country, as the statistics show. Understanding of these high-quality changes, the introduction of industry in the economic sector of the country, can best be seen in the example of the world's most powerful economy - the United States. How this power arose, what this country as a whole and in the region had to go through, what conditions were created for further growth, and what legacy this country has now, we are interested in all this as a fundamental example of building a successful economy. Conclusions. The effects of industrialization have helped the United States raise its status in the international arena by conquering new markets for its own products. Changes also happened in American society which realized it`s status in a world economy and supported such ideas as imperialism but these ideas have taken on a different form from the European model. Structurally, the United States has built a network of clusters that have created points of attraction and economic diversity in different parts of the country

So, we can summarize that the establishment of the training system on the one hand took place during the implementation of real-time training, and on the other – the participants of the educational process (teachers, students, interns, graduate students, doctoral students, teachers, students, parents, administrative staff, etc.) give large and common personal influence at the distance learning process. However, the system of secondary education still received a short "test" period to implement the transformation of all elements of classroom learning to the distance one. High educational institutions in Ukrainian educational space has been somewhat improved in distance learning a bit faster than schools by the availability of online educational resources (Moodle, repository, web resources of higher education institutions with elements of self-study), which have not yet been widely used in secondary schools generally.
