The analysis of individual micrometre- and submicrometre-sized particles collected by IAEA’s safeguards inspectors on swipe samples during in-field verification activities requires the implementation of a sustainable quality control system such as suitable microparticulate reference materials. To this end, pure and neodymium-doped uranium oxide-based microparticles utilising an aerosol-based particle production process were prepared. SEM/EDX measurements confirmed the monodispersity of the produced microspheres as well as the incorporation of 15 mol% Nd into the compound particles. The timeline of structural investigations mirror the ongoing alteration of particles being stored under laboratory atmosphere. While results from in-SEM Raman (CEA, DAM) on microparticles after two years storage time point to the formation of U3O8 and a minor fraction of schoepite phase (hydrated UO3), in U L3-edge XAFS after four months storage time and U M4-edge HR-XANES after ten months storage time spectra (INE-Beamline and ACT station @ KIT synchrotron radiation source) mainly U(IV) and U(V), respectively, was observed. These results provide new insight into ageing mechanism of the microparticles after preparation. From these results important conclusions with respect to storage conditions and shelf life of the reference particles can be drawn. The first batch of pure U-oxide microparticles produced in Juelich was successfully certified regarding the isotopic composition and the U amount per particle and applied in an international laboratory exercise NUSIMEP-9.

As of 2020, more than 400 nosologies of primary immunodeficiencies are known. For most children with this pathology, the key immunological diagnosis remains unclear due to the lack of pathognomonic symptoms, as well as low medical alertness due to the relative rarity of these diseases. Primary immunodeficiencies are not fatal if diagnosed early, moreover, they are treatable with the possibility of a full life or complete recovery. Today, information technology has become an integral part of everyday life. The ability to evaluate a clinical patient record online is a modern important step. Purpose — to create an online test, available to both physicians and patients, to detect suspicious cases of primary immunodeficiencies in children based on possible clinical manifestations. Material and methods. Collection and analysis of a child's clinical record on suspicious manifestations of primary immunodeficiency, age and gender comparisons using web technologies. (PHP, MySQL). Results. International and Ukrainian developments of clinical criteria for suspected primary immunodeficiency in a child have been transformed into an online test containing 35 clinical inquiries to a child's parents or attending physician, followed by analysis of a child's gender and age. As a result, the test user receives the result of the alertness level in terms of urgency to consult a pediatric immunologist. Conclusions. The immunological online test showed considerable interest, a high detection rate of suspicious cases of primary immunodeficiency. The test can be used with patients who come for an appointment or with hospital patients. The study was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the institution specified in the work. Informed consent was obtained from the parents of the children for the research. The authors declare no conflicts of interest. Key words: pediatric immunology, primary immunodeficiencies, online, test, clinical criteria.

Published: February 2021

Background. Mucopolysaccharidosis (MPS) type II is an X-linked hereditary disease from the lysosomal storage diseases group. The absence or malfunctioning of the iduronate-2-sulfatase enzyme leads to disruption in glycosaminoglycans (GAG) degradation. The GAG accumulation in lysosomes leads to dysfunction of various tissues and organs. There are neuropathic (severe) and non-neuropathic (relatively mild) forms of the disease. Early diagnostics of non-neuropathic form of MPS II is quite difficult due to slow disease progression and because early symptoms are hard to notice. Clinical Cases Description. This article describes three clinical cases of non-neuropathic form of MPS II. Patients had following symptoms: non-rough facial features changes (gargoylism), hepatomegaly, hernias, recurrent otitis, non-inflammatory joint contractures, and cardiac valves involvement. The children height conformed to the age or was little lower than reference values. The described form of MPS II is characterized with the absence of cognitive impairment. Conclusion. Enzyme replacement therapy efficacy has been shown via disease progression slowing down, significant improvement of clinical symptoms and quality of life.

Enamel defects (i.e. hypoplasia, diffuse and demarcated opacities), in particular Molar Incisor Hypomineralization (MIH), are alterations of dental enamel with underlying implications in affected children. A proper diagnosis and clinical dental records are needed to improve clinical management of enamel defects in primary health setting. This cross-sectional study aimed to determine the prevalence of enamel defects in 6-year-old children attending to Family Health Centres in Talca city and comparing the clinical diagnosis with that registered by general dental practitioners (GDPs) on the clinical dental records. Children (n=318) were evaluated by a calibrated examiner using the modified DDE index criteria. Almost half of children had enamel defects (47.5%; n=151). The proportion of children affected by demarcated opacities (36.8%; n=117) was higher than those effected by hypoplasia (13.8%; n=44) and diffuse opacities (12.6%; n=40). MIH prevalence was 19.8% (n=63) and 22% (n=14) of MIH-affected children presented the severe form. Clinical dental records registered by GDPs recorded 6.6% (n=10) of enamel defects, but the type of defect was not consistent with the clinical examination undertaken by the calibrated examiner. These findings suggest that enamel defects are prevalent in the studied population, but only few cases were registered in clinical dental records. To achieve diagnosis consensus, the registration section for enamel defects in the clinical dental record at Family Health Centres may need some improvement. Further diagnostic training for GDPs working in the public sector may also be necessary.

Published: February 2021

BACKGROUND: Telephone triage services (TTS) play an increasing role in the delivery of healthcare. The objective of this study was to characterize the users of a TTS for non-critical emergencies, describe the types of advice given and their subsequent observation, and assess the influence of TTS on the use of the healthcare system in a sanitary region of Switzerland. METHOD: Data from a TTS based in the French part of Switzerland will be analyzed. This service consists of a medical contact center for non-critical emergencies, with trained nurses available 24/7. We created a questionnaire based on literature search and inspired by other questionnaire to assess these different points. All calls for medical complaints from adults (people aged > 18 years old) during a 3 months period (from July 2018 to September 2018) will be listed. 20 calls per day will be randomly selected with the software STATA. Research students will contact users 2 to 4 weeks after the initial call to reach a total sample of 430 users. In this descriptive study, the main outcome is to evaluate if the call to TTS change the attitude of care (dichotmomous variable yes/no). We expected a change in 20% of users of CTMG (p = 0.2) with a 99% confidence interval of (15% - 25%). Using the general formula ?=??/22?(1−?)/?2 we find n = 425, being e=0.05 the half width of the desired confidence interval, ?=0.01 the 1’s complement of the confidence level (99%), and ??/2 the (1−?/2) quantile of the standard normal distribution (?=0.01 → ??/2 =2.58). We will use STATA15.0 to perform the statistical analyses.

Published: February 2021

The purpose of this paper is to explore the potential of synergising of two major theories that sprang from two entirely different disciplines, namely the human-computer interaction (HCI) and the arts. Indeed, there are vast and diverse gaps when two different theories, such as technology and art, are to be combined to develop a new element that complements to both disciplines. In this paper, the proposition is to measure the user experience when dealing with an art object that infuses with digital technology. Augmented reality (AR) derived from the HCI discipline and customarily to UX as a measurement tool. On the other hand, a comic is an aesthetic object that requires an aesthetic-friendly method as its measurement tool. Ultimately, this paper proposes an integration of the UX and AX theories to evaluate an AR comic.

Published: February 2021

With the widespread adoption of big data technology, the diversity of data sources is continuously evolving. Data service technology is a technology derived from providing effective data interfaces for data applications. Based on the adaptive deep learning algorithm, this study proposes an improved service plan. First, the problem of randomly selecting the sending location of the data packet in the asynchronous random service scheme was analyzed, which leads to the waste of channel resources. Then, combined with the adaptive deep learning algorithm, an adaptive service scheme is specified. For the problem of large delay, the data frame is divided into multiple uniform position intervals. Therefore, the user learns the position interval until the user tends to select a position within the fixed position interval to send the data packet. Furthermore, in the algorithm’s iterative process, adaptive deep learning was usedbased on the ability of the algorithm to perform intensive learning. A detailed analysis of the various scenarios, the essential mode of the technology, and the computer simulation of the throughput and packet loss rate indicators of the proposed scheme in the three environments are provided to demonstrate the superiority of the proposed scheme.
Permissioned vs. Permissionless Blockchain: How and Why There Is Only One Right Choice

Published: February 2021

The blockchain structure can be utilized in an efficient way to verify and ensure the integrity of the data and prevent historical transactions from tampering, such that if one block is altered, then the rest of next blocks are no longer valid. However, it is possible to re-calculate all the next blocks in a closed and permissioned network, such that all altered blocks will become valid again. In other words, only chaining blocks to each other, based on the hash of the previous one, cannot ensure the integrity and the security of the data and protect transactions against tampering. In this paper, we motivate why permissionless blockchain in an open network should be considered as the only acceptable type of blockchain and show that permissioned blockchain and closed network makes chaining transactions (i.e. blockchain) as an unhelpful structure. Of course, this never means that we ignore the existing problems in permissionless blockchains (such as, scalability of the network and transaction throughput), but also, we argue that permissioned blockchain cannot be an acceptable solution for those problems, where chaining transactions will no longer be meaningful. In other words, in a closed network, we no longer need to chain transactions. Although, this is a central issue and has been addressed in recent years, we are trying to bring new elements and an enriched point of view.

Gramaticalização do verbo ver: uma análise comparativa no português e no espanhol
Authors: Silva Izabel Larissa Lucena , Torres Fábio Fernandes
Published: February 2021

Este trabalho tem por objetivo analisar a gramaticalização do verbo “ver” no português e no espanhol, a partir de dados consultados em diferentes corpora digitais, orais e escritos, com base em Givón (1995, 2001), Gonçalves et al. (2007), Heine et al. (1991), Lehmann (2002 [1982]), Heine e Reh (1984), entre outros. Considerando-se a gramaticalização não apenas como um processo relacionado à mudança diacrônica de um item ou construção, mas também como um processo elaborativo-criativo motivado por aspectos cognitivo-comunicativos (GIVÓN, 1984), constatou-se que o verbo perceptual “ver” exerce diferentes funções, que podem ser distribuídas em um contínuo de abstratização semântica e mudança categorial.

Collocation and semantic prosody – a gauge for bias in political discourse?
Authors: Guilherme Pedro
Published: February 2021

This paper aims to outline the relationship between collocation, semantic prosody and political discourse, as these linguistic phenomena may appear in utterances that subliminally carry biased views. The analyses of different corpora – namely one comprised of 2016 Donald Trump’s presidential campaign speeches – shows that there are indeed cases of collocation and semantic prosody that display a certain degree of bias in the speakers, mainly Donald Trump. The president’s collocational patterns also suggest that his discourse falls in line with his populistic stance in politics. The paper then proceeds to discuss the dialogical relationship between the studied linguistic phenomena and society.
Пріоритетний алгоритм завантаження як частина оптимізаційної моделі завантаження повітряних кораблів

Published: February 2021

Мета: розробка нового алгоритму оптимізації завантаження з метою вирішення проблеми оптимального завантаження повітряних кораблів із подальшим впровадженням алгоритму у новітню модель оптимізації. Методи: евристика, формалізація, комп’ютерне моделювання.  Результати: був розроблений новий алгоритм оптимізації, який передбачає розташування груп контейнерів, мінімізуючи час завантаження. Обговорення: Більшість вивчених наукових праць містять різноманітні характеристики вирішення проблеми пакування, оптимізаційні моделі рюкзака, а також виділяють термін «завантаження повітряних кораблів» як проблему вибору контейнерів, пакування та завантаження у вантажний відсік повітряного корабля. Такі моделі сконцентровані на окремих аспектах, в той час як, у реальному часі, проблема оптимізації тісно пов’язана із здійсненням хендлінгових операцій. Вищезазначена новітня модель оптимізації завантаження передбачає декомпозицію проблеми завантаження та впровадження нового пріоритетного алгоритму його планування. Даний алгоритм відноситься до механізму попереднього розташування засобів пакетування у вантажному відсіку повітряного корабля заздалегідь, у пріоритетному порядку, з метою вивантаження згідно документів, із виключенням перевищень допустимих значень із центрування та завантаження та із зменшенням часу завантаження та послідовним скороченням хендлінгових та операційних витрат.

Мета: представлення результатів оцінювання після впровадження розробленої моделі оптимізації завантаження та аналіз адекватності цієї моделі з метою доведення її ефективності, за допомогою зменшення головного критерію – часу завантаження. Методи: експеримент, евристика, статистика, імітаційне моделювання. Результати: розроблена модель оптимізації завантаження пройшла усі процедури верифікації, а аналіз експериментальних даних підвищив її значущість у процесі авіаційного завантаження. Обговорення: Розглянуто деякі параметричні критерії оцінки адекватності моделей для зазначення, що ефективність моделі оптимізації завантаження не може бути оцінена саме за цими критеріями. Тому, оптимізаційна модель з часовими критеріями має бути проаналізована на предмет адекватності лише за непараметричними критеріями, а саме – за Т– критерієм Вілкоксона. Стаття надає результати аналізу експериментальних даних, що демонструють різницю між параметрами моделі та реальною тривалістю процедури завантаження / розвантаження у реальних умовах. Імітаційна модель підтверджує мінімізацію часу завантаження після імплементації оптимізаційної моделі. Отже, результати верифікації моделі можуть розцінюватися як заключна частина дослідження ефективності впровадження  інтегрованої мультикритеріальної моделі оптимізації завантаження повітряних кораблів.

Os microrganismos endofíticos, vivem no interior dos tecidos de plantas sem causar nenhum dano aparente ou sinal externo de infecção às mesmas e são pouco estudados. Esses residem, preferencialmente, nos espaços intercelulares mais do que nos espaços intracelulares dos tecidos vegetais e já foram detectados em plantas tropicais, temperadas e de florestas boreais. Os microrganismos endofíticos apresentam importante papel nos ecossistemas influenciando na biodiversidade das comunidades e mediando as interações ecológicas. Além disso, podem atuar na defesa das plantas, diminuir os danos causados por agentes patógenos, insetos, acelerar a emersão de sementes, promover o equilíbrio da planta em condições adversas e aumentar o seu crescimento. Nesse trabalho encontra-se uma breve revisão de artigos científicos que abordam o amplo espectro de atividades biológicas que compostos produzidos por microrganismos endofíticos podem executar, reforçando a importância desses como fonte de compostos de interesse medicinal.

Published: February 2021

Para mitigar o impacto do despejo indiscriminado de esgoto nos corpos hídricos são necessárias tecnologias de tratamento relativamente simples, eficientes e de baixo custo, destacando-se a disposição no solo (declivoso e vegetado) através do escoamento superficial. Neste trabalho, realizado em escala de bancada, comparou-se as concentrações de nitrogênio e carbono total no esgoto afluente a uma rampa contendo Brachiaria decumbens, com o coletado após os processos de escoamento superficial e infiltração na camada subsuperficial do solo. Avaliou-se o desempenho de uma rampa vegetada e contendo solo-exposto e ainda a remoção de fósforo do solo pela braquiária. Os resultados mostraram que a eficiência de remoção de nitrogênio utilizando B. decumbens foi próxima às relatadas por estudos realizados em escala real. A concentração de fósforo no sistema vegetado foi 52,8% menor do que a do não vegetado. A disponibilidade de fósforo no solo não foi fator limitante na sorção de nitrogênio pela espécie forrageira. Essa metodologia é viável, portanto, deve-se incentivar o seu uso como meio eficaz de tratamento de esgotos sanitários.

Modern state of technical means to remove uncontrolled vegetation
Authors:   Rostov State Transport University, Platonov A.A.
Published: February 2021

The article analyzes, systematizes and evaluates the demand for machines, mechanisms and equipment used to remove uncontrolled tree and shrub vegetation from the territories of linear infrastructural objects. The existing technological processes that form exclusively mechanical methods of removing unwanted tree and shrub vegetation are analyzed. The technical means of mechanization of work on the elements of the technological process used on the territory of linear infrastructure facilities are systematized. The predominant use of a specific number of technical means by implementing organizations is shown, indicating their characteristics and the main defining criteria of demand. It has been established that there is almost complete absence of both small means of mechanization, allowing to reduce the share of manual labor when carrying out work to remove unwanted vegetation in hard-to-reach places of the cleaned areas, and specialized pick-up loaders of felling residues. The definition of a technical means of raking up unwanted vegetation is proposed and formulated as a «forest rake» It was revealed that in a number of regulatory documents there are incorrect names for motorized hand-type brush cutters, corresponding recommendations for production are given. The results of the work can be used by enterprises engaged in the maintenance and operation of linear infrastructure facilities.

We studied the hereditary conditionality of species specificity of 8 poplar species by the starch content in the tissues of their shoots. The objects of research were: white pyramidal poplar: (P. alba L., f. piramidalis); black poplar (P. nigra L.); Italic poplar (P. nigra, var. italica Münchh.); Chinese poplar (P. Simonii Carr.); balsamic poplar (P. balsamifera L.); poplar larrity (P. laurifolia Ledeb.); white poplar (P. alba L.); aspen (P. tremula L.). Starch concentration in various tissues of annual shoots were established during microscopic studies with histochemical staining of preparations. Statistical processing of the actual material was performed using one-way and two-way anova. It was found that the types of poplars differed in the presence of starch in different tissues. The white pyramidal poplar and its typical shape showed similarities in its content. Aspen differed from them in a somewhat large amount of this substance. The species included in one section were more similar to each other, with a noticeable difference from the representatives of other sections. The difference in ratings between sections of black and balsamic poplars is less noticeable than between each of these sections and white poplars. The influence of the genotype on the formation of physiological differences reaches 72 %. Differences between accounting trees of the same species are less pronounced than between the taxonomic groups compared, and do not reach the level of significant ones. The species specificity of poplars growing in the Nizhny Novgorod region, according to the physiological characteristics associated with the starch content in the tissues of their shoots, is hereditary.
Role of Social Media in Shaping Public Risk Perception during COVID-19 Pandemic: A Theoretical Review
Authors: Tsoy Diana , Tirasawasdichai Tanin , Ivanovich Kurpayanidi Konstantin
Published: February 2021

Various national and global media outlets have daily reports and updates concerning the Coronavirus pandemic, reporting on the number of infected, quarantined, hospitalized and deaths, as well as new policy measures and restrictions introduced and implemented. While traditional media still plays a significant role in shaping risk perception, social media can be considered even more influential. The aim of the paper is to reflect on the impact of social media exposure during COVID-19 on perceived threat and efficacy by the implementation of PMT theory through EPPM model. We point to the interaction between the EPPM model and SDT (self-determination) theory in ‘Stay at home’ behaviour. The paper ponders on the usefulness of social media in achieving better preventive results among people. Social media platforms’ immense potential in forming peoples’ opinions and risk perceptions calls for crisis communication management on the part of governments, Security and Reconnaissance staff, and policymakers. Joining forces with leading scientists from various domains, such as epidemiology, governance, economy, and psychology, should create strong, potent and persuasive content tailored to fit the social media format and healthcare protection campaigns. The news should deliver the message clearly and reliably, following the suggestions of the EPPM model standard. In the instance of the ‘Stay at home’ campaign that promotes abiding with social distancing recommendations, experts should combine appropriate images, data and information according to fear-driving model, and provide reliable guidelines concerning protective measures citizens can take to ensure safety. Apart from freight inciting strategy, propaganda should focus on educating and emphasizing the effectiveness of complying with the norm.
(Im) posibilidad de escribir el trauma. El silencio en El profundo Sur de Andrés Rivera
Authors:   Universidad de Chile, Vidal Barría Cristian Ignacio ,   Chile
Published: February 2021

The questions around literary writing and its possibilities for representing violence and historical trauma is a current discussion in both philosophical and literary studies. This article addresses these complexities and examines, through a reading of the novel El profundo Sur (1999) by Argentine writer Andrés Rivera, the possibilities of the literary text as a device that tries to represent or depict violence and trauma through a fictional narrative. The novel takes as its setting and historical reference the massacre of workers in Buenos Aires in 1919, also known as the “Semana Trágica”. Rivera, whose aesthetics is marked by the use of the ellipsis, elaborates a reflection on language, fiction, and the reconstruction of a historical event through literature.

This article examines some dilemmas posed by the analysis of the academic field of research in the university system. In order to do so, we recur to the experience recorded in a biographical-narrative text done by a teacher-researcher. In this biographical record, the traces, marks and voices of devices that refer to performative forces that shape contemporary ideas of the university and that seek to perform the subjectivities and identities of academics are noticed. The dilemmas, although they are posed in a subjective register, are analyzed as effects of meaning generated by the instituting action of Academic Capitalism, the Global Reform of Higher Education and the Culture of Auditing as concurrent processes that operate in the regulation of the field. academic-scientific since the establishment of neoliberal policies in the Argentine university system since the nineties and that still persist. In this reading key, the unique dilemmas of the researcher bring out a dispute of meaning of greater scope generated by the transition towards a university model based on the logic and governance instruments of Academic Capitalism.

This article approaches entrance to higher education, in teaching formation programs, and seeks to find possibilities of intervention as regards drops in this level. We are interested in getting back an experience in process, among groups of early years students, which promotes academic accessibility in these times of sanitary emergency. From a sociocritical perspective in education we recover contributions from Birgin (2015), Ezcurra (2011) and Bourdieu (2007) to reflect on higher education entrance, in which inequalities -originated at lower levels- are reproduced, together with negative views translated into practices, and the absence of certain necessary habitus to be able to go through the teaching formation. It is interesting to register the analysis in an unprecedented present, from the irruption of virtual education, which has led to the resignification of bonds and group work in learning and teaching.

Published: February 2021

The prevalence of anxiety disorder in Indonesia increases significantly every year. It is worth special attention, especially in facing the uncertainty during pandemic. Acceptance and Commitment Therapy (ACT) is one of the third-wave cognitive behavior therapy (CBT), usually used for anxiety disorder treatment. In this research, I want to examine the effectiveness of Acceptance and Commitment Therapy (ACT) to decrease the level of Generalized Anxiety Disorder (GAD), taking General Anxiety Disorder-7 (GAD-7), Geriatic Anxiety Inventory (GAI), and Beck Anxiety Inventory (BAI), as the standard. It uses a meta-analysis techniques processed by statdirect trial version 2.0. It involves 17 experimental journals of ACT and GAD (n experiment group = 574; n control group = 513). The assessment of ACT and GAD bases itself on random effect size (I2 = 83.3%), without any publication bias (-3.88). The result shows that ACT is still effective to decrease the level of GAD (d= -.66; medium effect size). The result concludes that the ACT needs the assistance from other interventions. It also suggests research replication to multiply the references related to the effectiveness of ACT.

Published: February 2021

Amateur children’s and youth press (samizdat) has historical roots in Russia, including in the Siberian-far Eastern region. At each stage it was characterized by specific features conditioned by socio-cultural factors of the time. The purpose of the article is to analyze current trends in the development of children’s samizdat. The work is based on an extensive source database. The author analyzed data from “The Russian school press Register”, looked through PDF-versions and online school publications on the official pages of almost one hundred educational institutions in the region, as well as individual printed samples of children’s and youth amateur magazines, studied the sites “Dai Zin”, “Children’s samizdat” and a number of blog communities popular with teenagers. The investigation showed that in the first quarter of the new Millennium the unique phenomenon called samizdat is an actively developing part of the information space. There was a quantitative growth of children’s and youth (teenage) press. Its type-specific and content characteristics have become more diverse. Along with subcultural periodicals prepared by young correspondent, home-made book are also published. The rapid development of new information technologies has resulted in the emergence of new forms of self-publishing: online magazines, blogs of young authors.

This article provides an overview of the scientific productivity of the regions of the Republic of Belarus according to the data of the scientometric systems Scopus and Web of Science. The aim of the work is to present the results of bibliometric analysis of research activities in separate regions of the country. The following indicators are calculated: the number of organizations and publications, citations, average citations per article, highly cited publications. The performed analysis is relevant, since the topic of the regional distribution of publication activity in the Republic of Belarus has not been covered yet in the professional press. The analysis showed that the scientific productivity of the regions in Belarus is at a low level, even with the observed increase in publication activity in recent years. The results obtained can be used as initial data by specialists in their further research, heads of scientific organizations for making managerial decisions in the field of scientific policy, determining the most promising areas of research, etc. It is concluded that in order to improve the results of research activities of the territorial-administrative regions in the Republic of Belarus, it is necessary to actively develop national and international scientific cooperation.

Authors: Zheng Yasi , Liu Wenjun , Liu Yadong
Published: February 2021

We address the dynamics of two-dimensional Navier-Stokes models with infinite delay and hereditary memory, whose kernels are a much larger class of functions than the one considered in the literature, on a bounded domain. We prove the existence and uniqueness of weak solutions by means of Faedo-Galerkin method. Moreover, we establish the existence of global attractor for the system with the existence of a bounded absorbing set and asymptotic compact property.
