The process of implementing information technologies in all areas of economic, political, social life, etc. in the Republic of Moldova has also determined the evolution of cybercrime. New “virtual” dimensions of national infrastructure are being formed, which are becoming more and more important for local and international politics. As a result, in recent years it has been found that computer systems, networks and data are being used more and more frequently for criminal purposes, and the materials that could be evidence of these crimes are also stored and transmitted through these networks by perpetrators. Cybercrime, espionage, propaganda, diversion and excessive exploitation of personal data through electronic communications networks are used as basic tools at all stages of designing a hybrid security threat. Cyberspace-specific threats are characterized by asymmetry and accentuated dynamics and global character, which makes them difficult to identify and counteracted by measures proportional to the impact of the materialization of risks. Moldova is currently facing threats from cyberspace at the address of critical infrastructures, given the increasing interdependence between cyber infrastructures and infrastructures such as those in the financial banking, transport, energy and national defense sectors. The globality of cyberspace is likely to amplify the risks to them by affecting both the sector to the same extent private as well as public. Threats to cyberspace can be classified in several ways, but the most commonly used are those based on motivational factors and the impact on society. In the prevailing conditions cybersecurity is becoming one of the most important areas for ensuring internal security and the effective operation of state institutions in all spheres of social and economic life.

Medicamentos em contexto local indígena
Authors: Diehl Eliana Elisabeth , Almeida Ledson Kurtz de
Published: March 2021

O estudo sobre medicamentos em contextos locais é uma importante estratégia para a compreensão de como estão inseridos em diferentes realidades, entre elas as indígenas. No Brasil, ainda são raras as pesquisas que identificam os medicamentos que fazem parte do cotidiano dos povos indígenas. Esse trabalho examina os medicamentos encontrados (a “farmácia caseira”) nas casas Xokleng de uma aldeia da Terra Indígena (TI) Ibirama-Laklãnõ e o contexto de circulação e uso dos mesmos. A pesquisa de campo envolveu a observação participante e a utilização de entrevistas e questionário, esse último aplicado em setembro de 2008 e fevereiro de 2009. Nessa TI (em torno de 2.000 habitantes), cada uma das sete aldeias existentes na ocasião da pesquisa contava com um posto de saúde (PS), com agentes indígenas de saúde e auxiliares/técnicos de enfermagem próprios; dois médicos e um dentista atuavam em todos os PS; uma enfermeira permanecia no Polo-Base, como coordenadora, e outra atendia nas aldeias. Em 40 casas (95% do total) de uma das aldeias, foram identificados 456 medicamentos, sendo 21% genéricos. Segundo a classificação Anatômica Terapêutica e Química, destacaram-se os antieméticos, os analgésicos e antipiréticos, os anti-inflamatórios e antirreumáticos não esteroidais e os antibacterianos. Os comprimidos, as soluções orais em gotas, os xaropes e as pomadas se distinguiram entre as formas farmacêuticas. Os medicamentos foram prescritos pelo médico do PS e por outros médicos, entre outros profissionais de saúde, tendo sido ainda obtidos por automedicação. A aquisição dos medicamentos foi majoritariamente no PS da aldeia ou no Polo- base. Os dados indicam uma forte medicalização desse grupo indígena, estimulada por uma atenção à saúde caracterizada pelo assistencialismo hipermedicalizante, de caráter curativo. Além disso, osetor saúde ignora que a práxis dos usuários indígenas de como e quando usar os medicamentos é orientada pelos conhecimentos locais, experiência da doença e por conflitos de poder que intervêm  o acesso e distribuição de medicamentos.
Estado como fazenda de domesticação
Authors: Leirner Piero C.
Published: March 2021

Este artigo pretende explorar as possibilidades de uma divergência em relação ao tratamento usual que se faz em relação ao estado como parte de uma esfera política. Partindo da crítica à própria concepção de “político” como antagônica a uma esfera “doméstica”, ajusta-se a sintonia fina de uma concepção de estado ao modus operandi de seus agentes nativos, e tem-se como principal questão justamente o fato de que a faixa de transmissão em que o estado opera tem tantos canais quantos forem possíveis de se realizar através de seus agentes. Buscando entender essa profusão de faixas, tenta-se aqui polarizar em um caso etnográfico que tematiza certas imagens privilegiadas: ausência de estado, domesticação, inimizade, o indômito, o selvagem, tomados a partir do ponto de vista de uma etnografia com militares na Amazônia. A partir disso, busca-se aqui entender como se produziu uma imagem artificial da política como sinônimo de estado, tomando conexões etimológicas, históricas e antropológicas que mostram o imbricamento entre processos estatais e um vocabulário da domesticação, que produz uma espécie de agenciamento que estou chamando de fazenda de domesticação. Por fim, a hipótese a ser defendida é que político e doméstico não se constituem em polos antagônicos, mas, antes, que o político é domesticação.
Caipora e outros conflitos ontológicos
Authors: Almeida Mauro W. Barbosa de
Published: March 2021

Decidi trazer reflexões ainda informes sobre uma economia política da natureza e de entes não-naturais. Essas considerações dão continuidade a uma crítica em andamento ao relativismo antropológico. Parte dessa crítica consiste no reconhecimento do conflito entre ontologias, bem como das áreas de acordo entre elas. Mas por que é que uma conversa sobre a economia política nos trópicos traz consigo a palavra ontologia em seu próprio título? Esta é a primeira pergunta.
Matéria do Parentesco
Authors: Carsten Janet
Published: March 2021

Assumindo como ponto de partida o ensaio recente de Marshall Sahlins, What kinship is - andis not (2013), este artigo propõe uma série de reflexões sobre o momento atual do estudo antropológico do parentesco. A definição de Sahlins do parentesco como “mutualidade do ser” é ampla e inclusiva. Ao invés de focar no que é ou não o parentesco, me afasto da dicotomia englobante do “biológico” e do “social”. Ao contrário, uso sua discussão, assim como escritos sobre parentesco de outros acadêmicos, para ir além e pensar sobre “espessamento” e “diluição” do parentesco, sobre como ele é feito e dissolvido ao longo do tempo, sobre gradações de parentesco e sobre diferentes substâncias e metáforas por meio das quais esses processos ocorrem. Partindo de uma pesquisa de campo recente sobre sangue, assim como de minhas pesquisas anteriores, amplio as maneiras em que temporalidade e substância são mutuamente entrelaçadas, sugerindo que elas são intrinsicamente incorporadas no parentesco e nas capacidades que ele evoca.

Published: March 2021

Introdução: O processo de envelhecer é influenciado por diversos fatores, entre eles as doenças crônicas e os eventos adversos onde se destaca o evento quedas. As quedas de pacientes internados estão entre os principais eventos a serem prevenidos nas instituições e são prioridades dentro do programa de segurança do paciente. Elas podem acarretar consequências graves aos pacientes, como traumas, fraturas, dependência e morte. Objetivo: Identificar os cuidados de enfermagem, quanto ao evento quedas, para a segurança de idosos internados nas unidades de internação de clínica médica. Método: Pesquisa qualitativa do tipo exploratório-descritivo, realizada no período de março a abril de 2018, em duas unidades de Clínica Médica de um hospital escola, com Enfermeiros. A coleta de dados deu-se através de entrevista semi-estruturada, sendo essas gravadas, transcritas e analisadas segundo análise Minayo. Pesquisa aprovada pelo número: 80907517.5.0000.012. Resultados: Participarem 15 Enfermeiros, 14 mulheres e um homem.  Através das entrevistas identificaram-se três categorias: Medidas de prevenção para quedas, extrínsecas, intrínsecas e comportamentais (avaliação dos riscos de quedas, ferramentas, e medidas de prevenção); Cuidados de enfermagem aos idosos que tiveram episódios de quedas (cuidados imediatos e registros dos cuidados) e Notificação das quedas no ambiente hospitalar (realização, fluxo de encaminhamento, divulgação dos eventos e subnotificação). Conclusões: Foi possível concluir que os Enfermeiros conhecem os fatores de risco e implementam ações de prevenção para as quedas, entretanto não conhecem ou pouco utilizam ferramentas e protocolos que padronizem as ações e auxiliem nos cuidados diários ao idoso com risco de quedas.

Published: March 2021

Introdução: Doenças crônicas não transmissíveis são comuns em idosos, os quais podem apresentar descompensações e serem hospitalizados. No Brasil, o cuidado ao idoso é culturalmente realizado por um membro familiar. Muitas vezes, esse familiar assume a responsabilidade pelo cuidado de maneira repentina, sem nenhum preparo prévio ou apoio, o que pode resultar em intensa sobrecarga. Nesse contexto, pesquisadores apontam que o esgotamento físico e mental pode influenciar negativamente a qualidade de vida do cuidador. Objetivo: Avaliar a sobrecarga de cuidadores familiares de idosos inseridos no contexto hospitalar. Método: estudo transversal, quantitativo, realizado com 98 cuidadores familiares de idosos que estavam internados na Santa Casa do município de São Carlos-SP. Foram utilizados os seguintes instrumentos: Questionário de caracterização do cuidador, do contexto de cuidado e Inventário de Sobrecarga de Zarit. Na análise descritiva dos dados foram estimadas distribuições de frequências, médias, desvios padrão e proporções. Resultados: a maioria dos cuidadores era do sexo feminino (88,8%), com média de idade de 54,1±13,5 anos e casadas (74,5%). Cuidavam do seu progenitor (45,4%) ou cônjuge (32,0%), há 51,6±84,3 meses, durante 16,2±7,7 horas por dia, sem treinamento prévio (81,6%). Em relação à sobrecarga, o escore médio obtido foi de 34,3±16,9 pontos. Todos os cuidadores entrevistados apresentaram algum nível de sobrecarga, sendo a sobrecarga moderada mais prevalente (49,5%), seguida de moderada a severa (25,8%). Conclusão: cuidadores familiares de idosos hospitalizados apresentaram alta prevalência de sobrecarga. Torna-se necessário identificar precocemente essa condição para que sejam planejadas intervenções para melhorar a qualidade de vida desses indivíduos.

A leptospirose é uma zoonose de grande importância em saúde pública. Cento e quatro (104) amostras de urina de bovinos abatidos na região centro-oeste do Estado de São Paulo, Brasil, foram avaliadas para detectar Leptospira spp. As amostras foram mantidas em PBS e em culturas de EMJH e Fletcher. Observamos crescimento de microrganismos em 13 amostras do meio Fletcher, embora não tenha sido observado no meio EMJH. Por PCR, 25 animais (amostras) foram positivos com os primers LEP1 / LEP2, sendo que 16 amostras foram mantidas em PBS, seis em meio Fletcher e três em meio EMJH. As 25 amostras foram submetidas a PCR com o gene LipL32 para verificação da patogenicidade. Uma amostra amplificada e por sequenciamento resultou em 99,77% de similaridade com Leptospira kirschneri sorovar Canicola e Leptospira interrogans sorovar Pyrogenes. Este é o primeiro relato de isolamento de Leptospira kirschneri sorovar Canicola e Leptospira interrogans sorovar Pyrogenes em amostra de urina bovina na Região Centro-Oeste do estado de São Paulo, Brasil. Concluímos a importância da leptospirose no rebanho avaliado e a atenção para o risco ocupacional, devido à possibilidade de urina contaminada nas pastagens e disseminação da infecção para outros animais e pessoas contactantes.
A narrative inquiry of nursing experiences during the Covid-19 pandemic
Authors: Vitale Susan Ann , Lowers-Roach Maureen , Lumley Lisa A.
Published: March 2021

This research focused on nursing care during the early phase of the Covid-19 pandemic. The experiences of 18 nurses and 3 nurse practitioners were analyzed through qualitative narrative inquiry. Riessman’s analytic approach guided identification of thematic similarities. The nurses in this study were emotionally exhausted by the rapid rise in patients and the daily death toll. The challenge of so many gravely ill cases required creative adaptations to address overcrowding and lack of resources. Teamwork proved immeasurable. Nurses advocated for their patients and families and were proud to have worked in this emergency. Nurses dealt with stressors by maintaining prior coping practices and developing new ones and relied on support from their family, hospital and community. A common objective was to establish and maintain the highest-possible levels of care in spite of challenging conditions. Proficiencies developed in coping with unprecedented challenges can help plan for future healthcare crises.
Examining the Degree of Foreign Trade Dependence and Its Influence on GDP Growth
Authors: Nuhanović Senija , Nurikić Mirnesa Baraković
Published: March 2021

Contemporary international economic environment registers an increasing relationship and interdependence of countries regardless of the degree of their development. In the open economy, the development of foreign trade mainly implies the growth of gross domestic product (GDP). The basic goal of this paper is to examine the influence and effects of trade dependence on GDP. Trade dependence is used to describe a country for which exports and imports are very important. This coefficient also shows the degree of national economy openness. The analysis included the area of Bosnia and Herzegovina for the period 2010-2018, whereby the relevant statistical data were processed for export, import, GDP, as well as the selected coefficient of foreign trade dependence. The results showed the existence of a short-term or long-term relationship between GDP and the total export and import, as well as between GDP and export.
Refugee Crisis in North America: Comparative Case Study of the United States and Canada
Authors: Dossan Zhanna
Published: March 2021

The US continues to lean toward a traditional, negative approach (Gomez, 2018) and to encourage cultural diversity in Canada. In their initial immigration legislation, the Canada and US shared profound resemblances: both began with Euro- and Christian-centered laws in order to limit the influx of migrants from Southern/Eastern Europe and Asia. The researcher has taken an empirical approach to a comparative methodology, and performed a study of the immigration policies of each country empirically. Both qualitative and also quantitative data analysis approaches were used for the present research. The findings of the research suggest that the two countries share some of the foundational similarities concerning their initial immigration law. For instance, this includes the inception of their policies with the base as Euro and Christian policies, where both attempted to achieve restricted migration flow from the Asia as well as Southern/Eastern Europe. However, with time, the changes in the migration policies have occurred due to the diverging socio-cultural as well as geographical aspects.

De last tot een uitgave van geld of goed: verplichting en vorderingsrecht?

In dit artikel bespreekt de auteur de last tot uitgave van geld of van een goed, al dan niet ‘uit de nalatenschap’, aan een of meer personen ten laste van een of meer (of de gezamenlijke) erfgenamen. De keuze van de wetgever om een dergelijke last niet meer als schuld van de nalatenschap te beschouwen, en de daaruit voortvloeiende aanpassingsoperatie van de nodige bepalingen in Boek 4 BW, heeft soms tot onnauwkeurige, soms tot inconsistente en soms zelfs tot onjuiste resultaten geleid.

Expert Judgement gives crisisteam continuous insight in the effectivity of measures

Crisis teams from waterauthorities want to have insight into the current risks for the area. The ‘Continuous insight’-method is used by them to monitor the risks of drought and high water and to draw up what-if scenarios for training and exercise. Various cases have now shown that Expert Judgement can be used to gain a clearer picture of the effectiveness of measures and to take a more balanced decision. The Expert Judgement method has been tested and applied by a group of international experts as part of the EU project DRIVER +. During an extreme situation, the crisis team may encounter dilemmas. The engaged group of experts follows a fixed procedure to provide advice to reduce flood risk evacuate to prevent loss of life.

Each expert makes his own assessment of the effect and impact of the measure envisaged. Each expert provides an explanation of the individual assessment. Then, under the guidance of a process supervisor, the experts discuss individual assessments and exchange arguments. This can lead to new insights. Each expert makes his own assessment again. The result is a probability distribution of estimates and an expected value. This expert assessment of the measure is taken to the crisis team, so that the chance of success and the assessment of the consequences of the proposed measure can be adjusted. The crisis team can take the decision immediately afterwards.

By following this procedure risk information is made visible. By linking expert knowledge with observations, a better substantiated expectation can be drawn up. According to the participants in the international meetings, the Expert Judgement method in combination with ‘Continuous insight’ helps to make better informed and faster choices. The method fits within the existing crisis management structure. The next step is to implement this method in the day-to-day affairs of crisis management.
Thermal characterization of halloysite
materials for porous ceramic preforms
Authors: Kujawa M. , Suwak R. , Dobrzański L.A. , Gerle A. , Tomiczek B.
Published: March 2021

Purpose: The aim of the study was to investigate the possibility of sintering raw (natural)
halloysite and pure halloysite to produce porous ceramic preforms, and determination of
sintering temperature based on the results of investigations into thermal effects, linear
changes and phase transitions.
Design/methodology/approach: Due to mullitisation ability of halloysite at high
temperature, alternative applications based on the sintering technology (including the
production of reinforcement of metal matrix composites) are being searched for. Pure
halloysite and Dunino halloysite were selected for the study.
Findings: Pure halloysite, characterized by low impurities, dimensional stability during sintering,
softening temperature above 1500ºC and ability to transform into mullite at temperatures above
950ºC could be used as a base for the production of sintered, porous mullite preforms.
Research limitations/implications: Presence of impurities in Dunino halloysite,
contribute to the shift of the sintering temperature towards lower temperatures and caused
a rapid and uncontrolled shrinkage of the sample and the appearance of the softening
temperature at 1300ºC.
Practical implications: Based on the research of thermal (DTA/TG, linear changes in
high-temperature microscopy) and XRD studies it is possible to determine the sintering
temperature of pure halloysite to manufacture the porous mullite preforms with open porosity.
Originality/value: The received results show the possibility of obtaining the new mullite
preforms based on pure halloysite.
A study of bearing capacity of skirted
octagonal footings resting on different
sands
Authors: Thakur A. , Dutta R.K.
Published: March 2021

Purpose: After a thorough study of literature it is concluded that the studies related to
unskirted/skirted octagonal footings on sand have not yet been investigated. Thus, this
paper presents a numerical analysis to assess the ultimate bearing capacity of the unskirted,
unskirted-embedded, singly and doubly skirted octagonal footings resting on different sands
(S1, S2, and S3). The length of skirt and depth of the embedded footing were varied from
0.0B to 1.5B.
Design/methodology/approach: The numerical square and octagonal footing with singly
and doubly skirted footing models were developed using Plaxis 3D software.
Findings: The results of the doubly skirted octagonal footings ultimate bearing capacity
were marginally higher in comparison to the singly skirted footing at all normalised skirt
depths as well as for all sands up to a Ds/B ratio 0.25 beyond which the increase in the
ultimate bearing capacity in case of doubly skirted footing was appreciable.
Research limitations/implications: The results presented in this paper were based on
numerical analysis. However, for the actual footings the soil placement and compaction,
details of skirt construction and the stress level will be different from the numerical analysis.
Further investigations using full-scale numerical models simulating field size footings were
recommended to generalize the results.
Originality/value: No such study on singly and doubly skirted octagonal shaped footings
were conducted so far. Hence, an attempt was made in this article to predict the bearing
capacity of those footings using Plaxis 3D.

for educational institutions and scientific
establishments
Authors: Kozub P. , Kozub S. , Lukianova V. , Borysova L. , Taraduda D. , Kachur T.
Published: March 2021

Purpose: To develop a new concept of laboratory support for learners at different levels of
education to maintain a high education quality in conditions of limited opportunities, such
as lockdown, lack of funding, etc.
Design/methodology/approach: To create a new concept, the practical experience of
school teachers, educators of technical colleges and universities, research workers, as well
as experience of scientists in the educational field published in open information' sources
was taken into account. The development of a new concept was carried out from 2014 to
2016, and its implementation, introduction into the educational process, and possible ways
to solve technical and organizational difficulties from 2016 to the present. In the last year,
special attention was paid to distance learning.
Findings: The development and the first practical steps to implement the new concept
of updating the laboratory support of educational institutions clearly demonstrate of its
practical implementation' feasibility. Positive consequences from the implementation were
identified as constant improvement of laboratory equipment, increase in the educators’ level,
transformation of virtual distance learning based on lectures and videos into real learning
with "live" visual demonstration of physical, chemical, biological and other processes
and experimental research. As a recommendation, should wish that at the state level to
recommend the implementation of this approach and to propose some legal mechanisms
to overcome identified problems.
Research limitations/implications: The present study was conducted for Ukrainian
educational institutions with the involvement of foreign students from different countries
studying in Ukraine.
Practical implications: The introduction of a new concept into the educational process
in countries with a weak economy will improve the educational quality and reduce the cost
of creating laboratory support.
Originality/value: Equipment should not only be a teaching tool, but also a teaching
subject.
Managing Experiential Co-creations in Cooperative Networks – Learnings from Tourism
Authors: Bieger Thomas , Laesser Christian
Published: March 2021

Tourismus ist ein multidimensionales Phänomen, das nicht nur einen wichtigen globalen Wirtschaftssektor darstellt, sondern auch geografische Muster, soziale Gemeinschaften, regionale Wirtschaftsnetzwerke und politische Beziehungen beeinflusst. Aufgrund der umfassenden Natur und des integrativen Charakters des Tourismussektors gab es schon immer Bestrebungen, diesen Untersuchungsgegenstand auf der Grundlage systemischer und disziplinübergreifender Ansätze zu analysieren. Eine der Haupteigenschaften touristischer Dienstleistungen ist die Abhängigkeit von Co-Kreationen, denn touristische Produkte bestehen aus verschiedenen Dienstleistungselementen, die von unabhängigen Unternehmen zusammen mit Kunden erbracht werden. Diese Sonderausgabe enthält Beiträge, die verschiedene Perspektiven auf die Koordination der touristischen Dienstleistungskette abdecken. Es enthält auch Artikel, die sich mit wichtigen Ressourcen mit öffentlichem Gut-Charakter für touristische Unternehmensnetzwerke und Destinationen befassen, wie z.B. Daten und Qualität von Arbeitsmärkten. Zweitwohnungen eröffnen den Zugang zu wichtigen Ressourcen für Destinationen. Die unterschiedlichen Rollen von Kunden als Koproduzenten, Kunden und sogar Investoren sind ein Thema, das ebenfalls behandelt wird.de

Improving the Orchestration Resilience of a Smart Integrated Tourism Destination – A Case Study in the Swiss Alps
Authors: Nanchen Benjamin , Bovier Anyssia , Golay Benoît , Salamin Jérôme , Fragnière Emmanuel
Published: March 2021

Most tourism destinations in Switzerland are fragmented. The result is that actors along the customer’s journey intervene in a disordered way. To create a smart integrated tourism destination, we posited that collaboration between these different actors should be trained upstream, in the design process. However, this training requires a laboratory independent of day-to-day business activity and allowing a type of rehearsal by the local stakeholders in the tourism industry. Through a case study based on SWISSPEAK Resorts (SPR), this research article illustrates that merely creating a digital marketplace for tourism is not enough to ensure a truly smart, integrated customer experience. Based on consecutive pre-experiments, we concluded that digital trust was of primary importance for the resilience of a smart integrated tourism destination and that orchestrating and rehearsing it was essential.
Kooperative Bildungsstrukturen zwischen der Hotellerie und der Wissenschaft als Erfolgsmodelle für Arbeitgebermarkenbildung und Mitarbeitergewinnung
Authors: Bohne Hartwig
Published: March 2021

Dieser Beitrag zeigt Erfolgskriterien gemeinsamer Personal- und Bildungsprojekte von Hotelunternehmen und Hochschulen mit hotelspezifischen Studienangeboten auf. Beeinflusst durch demografische Entwicklungen und eine veränderte Präferenzordnung gewinnen Markenschärfung und Personalgewinnung an Bedeutung, so dass Kooperationsmodelle ein lösungsorientiertes Instrument darstellen, um auf Marktentwicklungen strategisch-innovativ zu reagieren. Als Referenzmodelle werden sowohl die Typologie-Matrix mit zehn unterschiedlichen Kooperationsmodellen als auch der ASP-Trialog eingesetzt, aus denen sich die drei Erfolgsfaktoren privilegierter Bildungspartnerschaften „Attraktivität“, „Sicherheit“ und „Persönlichkeit“ ableiten lassen. Dadurch können mit intelligenten Kooperationsmodellen nachhaltige wirtschaftliche Vorteile erzeugt werden, so dass Bildung als Markenkern eines attraktiven Arbeitgebers interpretiert wird. Kooperationsfähigkeit und -wille werden dadurch zu einem strategischen Erfolgsfaktor der Hotellerie.

This chapter presents a novel method for compressing satellite imagery using phase grating to facilitate the optimization of storage space and bandwidth in satellite communication. In this research work, each Satellite image is first modulated with high grating frequency in a fixed orientation. Due to this modulation, three spots (spectrum) have been generated. From these three spots, by applying Inverse Fourier Transform in any one band, we can recover the image. Out of these three spots, one is center spectrum spot and other spots represent two sidebands. Care should be taken during the spot selection is to avoid aliasing effect. At the receiving end, to recover image we use only one spectrum. We have proved that size of the extracted image is less than the original image. In this way, compression of satellite image has been performed. To measure quality of the output images, PSNR value has been calculated and compared this value with previous techniques. As high-resolution satellite image contains a lot of information, therefore to get detail information from extracted image, compression ratio should be as minimum as possible.
Nomophobia Kids and Proprioception
Authors: Vaishnavi Giridharan
Published: March 2021

Proprioception is the sense of self movement and body position. The CNS integrates proprioception and other sensory system such as vision and vestibular system in order to create body position, movement and acceleration. It is developed by movement and works with surroundings. Children using smartphones for a long time result greater impact on the sensorimotor function and their proprioception is affected. In this topic, the write up is going to be regarding the proprioceptional deficit and the problems associated because of that of children using mobile phones for a prolonged period of time. The proprioceptive system has an extensive influence at the protection of human fitness. When the proprioception is dysfunctional, the vital anxious device does no longer recognize the ideal fame of tonicity of the muscular tissues at rest or in motion, does no longer combine effectively the records that comes from sensory receptors, and has issue in modulating multi-sensory integration, with outcomes in motor behavior and cognitive function.

Published: March 2021

This chapter is focused on the massive potential and increasing interest on Fluorinated Ionic Liquids (FILs) as task-specific materials. FILs are a specific family of ionic liquids, with fluorine tags equal or longer than four carbon atoms, that share and improve the properties of both traditional ionic liquids and perfluoro surfactants. These compounds have unique properties such as three nanosegregated domains, a great surfactant power, chemical/biological inertness, easy recovery and recyclability, low surface tension, extreme surface activity, high gas solubility, negligible vapour pressure, null flammability, and high thermal stability. These properties allied to the countless possible combinations between cations and anions allow the design and development of FILs with remarkable properties to be used in specific applications. In this review, we highlight not only the unique thermophysical, surfactant and toxicological properties of these fluorinated compounds, but also their application as task-specific materials in many fields of interest, including biomedical applications, as artificial gas carries and drug delivery systems, as well as solvents for separations in engineering processes.
Anisotropic Mechanical Properties of 2-D Materials
Authors: Li Qiang
Published: March 2021

While prior reviews and research articles focused on the various synthetic routes and microstructural controls of 2D nanomaterials as well as their functional applications, this chapter discloses the anisotropic behaviors of 2D materials and puts emphasis on the mechanical anisotropy of three distinct 2D materials, namely graphene, MoS2 and Al alloy coating, representative of carbon, inorganic and metallic 2D crystalline materials. Except for the relatively low interlayer cohesive stress, the in-plane anisotropy of the former two materials classes is subjected primarily to the hexagonal structure of the unit cells of the graphene and MoS2. The anisotropy of metallic thin films with high-density grain boundaries with preferential directionality, rendered by the non-equilibrium synthetic methods, results from both the conventional Taylor factor and the directionality of the grain boundaries. Despite 2D materials’ wide spectrum of applications, such as electronics, energy devices, sensors, coating etc., the mechanical anisotropy could be critical for certain mechanical applications, such as friction, and provide instructions on the durability, reliability and property optimization in the various applications of different 2D materials.
Felty’s Syndrome
Authors: Gorodetskiy Vadim
Published: March 2021

Felty’s syndrome (FS) is an uncommon subset of seropositive rheumatoid arthritis (RA) complicated by neutropenia with or without splenomegaly. The pathogenesis of neutropenia in FS is still not fully understood, but it is believed that the principal cause is neutrophil survival defect. Autoantibodies against peptidylarginine deiminase type 4 deiminated histones, glucose-6-phosphate isomerase, and eukaryotic elongation factor 1A-1 antigen may contribute to neutropenia development in FS patients. Splenic histology in FS shows non-specific findings and spleen size do not correlate with neutropenia. Cases of T-cell large granular lymphocytic leukemia with low tumor burden in blood and concomitant RA are clinically indistinguishable from FS and present a diagnostic challenge. Examination of T-cell clonality, mutations in signal transducer and activator of transcription 3 gene, and the number of large granular lymphocytes in the blood can establish a correct diagnosis. Optimal approaches to therapy for FS have not been developed, but the use of rituximab seems promising. In this chapter, the epidemiology, pathogenesis, clinical manifestations, differential diagnosis, and treatment options for FS are discussed.

The subject of research in this article is a comparative analysis of the condition, causes and consequences of poverty in Serbia and the surrounding countries. Poverty as a multidimensional phenomenon, on the one hand, implies insufficient income to meet basic living needs, while on the other hand, it also covers various aspects of human rights, such as' inability to employ, inadequate housing and inadequate access to social protection for health, education and communal services. Due to a significant decrease in economic activities, but also due to the effect of numerous noneconomic factors, in the Republic of Serbia and the surrounding countries the last three decades there has been a decrease in the standard of living of the population and a concomitant increase in poverty. The results of the research indicate that economic growth and development, with a proactive role of the state in improving social protection systems, better education and development of social entrepreneurship, are key factors that contribute to employment growth and living standards, and consequently the decrease in the poverty rate.

Coronavirus crisis from 2020 in USA is a mixture of financial and economic crisis that happened in 1929-33 and 2007-09. The body of work is permeated with attitudes in regards to the coronavirus crisis from 2020 and previous financial crisis from 2007 to 2009 by the world renowned economists and Nobel Prize winners Joseph Stiglitz and Pol Krugman and former presidents of the Federal Reserve Bank Ben Bernanke, Alen Greenspan and others. The US Federal Reserve Bank opted with a relaxed approach to the monetary politics during the coronavirus crisis - a new-old approach that they picked many times before. Current coronavirus crisis measures to the monetary politics in USA on one side will contribute to deflation while on the other side it will grow consumption and production with delay until 2021. Because of the social distancing during the coronavirus crisis, new problems emerged like the economic distancing of the USA economy, enormous debts to FRB on all levels because of emission of securities, bonds, mortgage and other form of securities which caused growth of activity of the top notch monetary institution in USA.

The key elements of serendipity are luck and contemplation. The discovery process includes the recognition of the finding potential based on knowledge and experience. Serendipitous discoveries are common in biomedical sciences. A significant number of pharmaceuticals is the result of serendipity. Drugs belonging to antimicrobial agents, central nervous system active substances as well as antitumor agents, gained great benefit from serendipity conditions. Besides in the traditional, irrational approach in the drug design, serendipitous discoveries have also played role in modern strategies, such as the drug repositioning and the development of multi-target antitumor agents. Serendipitous drugs discoveries can be classified as laboratory or clinical ones, depending on the drug development stage and the circumstances under which the combination of unforeseen events, the knowledge and skills of the researcher occurred. The discovery of a new drug is impossible without outstanding science as well as the dedication, freedom, and open-mindedness of the researcher to act, think, take a risk, and challenge dogmas.
Iritable bowel syndrome as the first manifestation of Hashimoto's tireoiditis
Authors: Jandrić-Kočić Marijana
Published: March 2021

Introduction. Hashimoto's thyreoiditis has a complex effect on the gastrointestinal tract, which includes hormone receptor alteration, neuromuscular disorders, myopathies caused by intestinal wall infiltration. Case report. A 44-year-old patient appears in the family medicine clinic due to moderate pain in the lower part of the abdomen present for the past three months, which intensifies before defecation and stops immediately after defecation. He has two to four liquid stools daily in which he has not noticed the presence of mucus or blood for the past two months. He negates earlier illnesses as well as diseases relevant to heredity. Physical examination provides a neat finding. Ultrasound examination of the abdomen is within the age range. Thyroid ultrasound identifies the right flap of a 48x24x10 mm diametre with hypoechogenic calcified nodus 14x12 mm in diameter (meets the criteria of the American Thyroid Association for aspiration biopsy), left flap of 44x20x14 mm diameter. The following are the laboratory findings: TSH 7.66 mIU/l, FT4 6.42 pmol/l, TG 5080 ng/ml, calcitonin 8.94 pg/ml, TG-At 24.99 IU/ ml, TPO-At 500 IU/ml. The patient is instructed on a hygienic dietary regimen and includes spasmolytic and antidiarrheal, and referred to a nuclear medicine specialist who performs an aspiration biopsy (TBSRTC IV follicular tumor). The Oncology Consilium indicates surgery (right-sided lobectomy) with extempore verification and further follow-up. Pathohistological examination of the removed right lobe excludes the presence of malignant disease (struma coloides multinodosa glandulae thyroideae). Antidiarrheal therapy is discontinued and replacement therapy is administered (levothyroxine sodium tablets 50 mcg, qd). Subsequent proctosigmoidoscopy shows a neat finding. One year after surgery the patient is in remission of the disease. Conclusion. Diagnostic evaluation of the thyroid gland in patients with irritable colon syndrome significantly improves quality of life, reduces occupational absenteeism and health care costs.
