Published: February 2021

Latar Belakang: Literasi kesehatan adalah kemampuan seseorang untuk mendapatkan, memproses dan memahami informasi serta pelayanan kesehatan dasar yang diperlukan untuk mengambil keputusan yang tepat mengenai kesehatan. Penelitian mengenai bagaimana literasi kesehatan berkaitan dengan status kesehatan seseorang masih belum banyak dilakukan di Indonesia, terutama karena belum adanya instrumen yang layak untuk mengukur tingkat literasi kesehatan. Penelitian ini bertujuan untuk mengadaptasi versi singkat dari instrumen Health Literacy Scale yang dikembangkan di Uni Eropa (HLS-EU-Q16) agar dapat digunakan untuk kelompok usia remaja akhir dan dewasa muda di Sumatera Barat. Metode: Penelitian kualitatif ini mengambil data melalui wawancara kognitif dengan 10 mahasiswa tingkat pertama di Universitas Andalas, Sumatera Barat yang direkrut secara purposif pada Juni 2019. Panduan wawancara dikembangkan dari 16 pertanyaan dalam instrumen HLS-EU-Q16 yang telah diterjemahkan ke dalam Bahasa Indonesia. Hasil: Secara umum informan banyak yang kurang paham dengan penggunaan frasa yang baku (seperti â€œmengambil keputusanâ€, â€œmembutuhkan pemeriksaan kesehatanâ€ dan â€œmenilai mana perilaku sehari-hariâ€ serta informan mengakui kesulitan memahami kosa kata â€œdokter lain atau second opinionâ€). Kesimpulan: Instrumen HLSE-EU-Q16 dapat digunakan untuk kalangan usia remaja akhir dan dewasa muda dengan penyesuaian pada pilihan frasa yang lebih mudah dipahami.

Investigation of power transformers technical condition in the Murmansk region and methods for their protection from the influence of geomagnetically induced currents.
Authors:   Northern Energetics Research Centre, Aksenovich Tatiana V.
Published: February 2021

The location territorial features of the Murmansk region electric power system determine its susceptibility to geomagnetically induced currents flowing through the dead-grounded neutrals of the transformers (autotransformers) during geomagnetic storms. The current values can sometimes reach tens of amperes and lead to half-period saturation of the steel core, and as a result to loss of reactive power, the appearance of harmonics, vibrations and windings overheating. All this can cause an emergency shutdown of lines or failure of the equipment itself. The article considers the analysis of the transformers and autotransformers technical condition of substations of voltage classes 110–330 kV on the Kola Peninsula. Statistics on the core types of the devicesare provided. Existing methods to reduce the effect of geomagnetically induced currents on transformers, as well as their advantages and disadvantages, are discussed.

Published: February 2021

At the moment, constraint programming technology is a powerful tool for solving combinatorial search and combinatorial optimization problems. To use this technology, any task must be formulated as a task of satisfying constraints. The role of the concept of global constraints in modeling and solving applied problems within the framework of the constraint programming paradigm can hardly be overestimated. The procedures that implement the algorithms of filtering global constraints are the elementary “building blocks” from which the model of a specific applied problem is built. Algorithms for filtering global constraints, as a rule, are supported by the corresponding developed theories that allow organizing high-performance computing. The choice of a particular software library is primarily determined by the extent to which the set and method of implementing global constraints corresponds tothe level of modern research in this area. The main focus of this article is focused on an overview of global constraints that are implemented within the most popular constraint programming libraries: Choco, GeCode, JaCoP, MiniZinc.

Authors:   Institute for Informatics and Mathematical Modelling KSC RAS, Balbukova E.V. ,   TGC-1 Training Center
Published: February 2021

When operating a thermal power plant (TPP), it is of great importance to ensure the reliability and safety of the enterprise while minimizing the cost of maintenance and repair of equipment. The currently used strategy for preventive maintenance is to carry out periodic work at predetermined times, regardless of the technical condition of the equipment. At the same time, the operating timefeatures, heterogeneous loads and, consequently, various equipment wear are not taken into account. Almost always there is an episodic deviation of the operating parameters of a particular equipment from the nominal values, which leads to an intensification of the wear processes and thereby a decrease in the residual life of this equipment. Therefore, the urgent task is to create tools for information and analytical support for planning repair and maintenance work based on the assessment and prediction of the condition of equipment using data from operational monitoring and computer modeling. In this paper, we pose the problem of creating an information system for assessing and predicting the states of an energy boiler as one of the key nodes of a TPP.

Coupling biocatalysis with high-energy flow reactions for the synthesis of carbamates and β-amino acid derivatives
Authors: Leslie Alexander , Moody Thomas S , Smyth Megan , Wharry Scott , Baumann Marcus
Published: February 2021

A continuous flow process is presented that couples a Curtius rearrangement step with a biocatalytic impurity tagging strategy to produce a series of valuable Cbz-carbamate products. Immobilized CALB was exploited as a robust hydrolase to transform residual benzyl alcohol into easily separable benzyl butyrate. The resulting telescoped flow process was effectively applied across a series of acid substrates rendering the desired carbamate structures in high yield and purity. The derivatization of these products via complementary flow-based Michael addition reactions furthermore demonstrated the creation of β-amino acid species. This strategy thus highlights the applicability of this work towards the creation of important chemical building blocks for the pharmaceutical and speciality chemical industries.
Functional load of gradation of evaluative meanings in woman’s portrait descriptions (based on the material of modern Ukrainian women’s prose)
Authors: Shevchuk Zoreslava
Published: February 2021

The article attempts to analyze the estimated value of language units by finding out their functional load on the gradation scale in woman’s portrait. The interpretation of the key concepts “portraiture”, “rating scale” is given. Due to the broad approach to modeling of woman’s portrait in fiction, the concept of “gradation” as a category that reproduces the positive / negative attitude to the object and, accordingly, its movement on the scale of general evaluation is proposed to interpret. The main markers of the expression of gradation in woman’s portrait descriptions are adjectives, adverbs, pronouns, which has been found. They intensify or de-intensify the meaning on the scale of traditional (established) antinomies. The role of color names on the gradation scale is determined (to characterize the hair of a woman with a red nucleus). The gradation of the estimated value of language units in other descriptions of the internal state, the character of a woman (mostly with negative values) is reproduced. The gradation series of nomenclatures is demonstrated, in which the process of formation of original paraphrased nominations is traced.
Terms of morphemic and word-formation in the East Slavic grammars of the 16th century
Authors: Ariskina Olga
Published: February 2021

The work is devoted to a multidimensional consideration of the terminology of morphology and word-formation in the East Slavic grammars of the 16th century. (The Grammar of 1586, The Grammar "Adelfotis" in 1591, The Grammar of Lavrеntii Zizanii in 1596)
The term is a linguistic unit for special purposes, which is the verbalized result of professional thinking, which denotes the concept of a certain scientific theory and serves to coding (concentration, fixation, storage), transmission (transfer of information), communicate, transmutation of knowledge (cognition: comprehension, processing, augmentation) and orientation in a certain special area, therefore an important place in describing the terminology of the past is assigned to the orientational aspect, which allows us to analyze the terms not only from the perspective of origin, word-formation, functioning, but also from the perspective of the explanation of the rationality of the author's nomination and the appropriateness of the perception of it by the addressee. Terminology is explored through the prism of the linguistic persona of grammarians by using the method of logical-semantic analysis.
At the stage of generation of the terminology of the doctrine of morphemic and word formation, the large number of calquing terms (almost 50% of the total number) was used. The Russian basis of the calquing was found out, which consists in the existence in the Russian language of the lexical-semantic method of derivation. Also for this stage, the functioning of terms formed by substantivation is characterized.
Dynamics of the exponent of terms of morphology and word-formation of the XVI century is due to the variation and synonymy, the dynamics of significatum – the reality (changes in language) and the development of scientific knowledge.
In the XVI century the terminological system in the field of word-formation is formed as a system, with enough clearly appeared hypo-hyperonical relations.
Reframing Working, Rethinking Learning: The Future Skills Turn
Authors: Ehlers Ulf-Daniel , Eigbrecht Laura
Published: February 2021

Research on Future Skills is one of the current hot topics in education, management and organizational research. In times of global networked organizations and steadily accelerating product cycles, the model of qualification for future jobs seems debatable. Can we really prepare graduates and employees for the future by the predominant model of knowledge acquisition? Do we already have adequate concepts for competence development in higher education and work environments? An international study led to the identification of the change processes that the working and learning world are undergoing as well as of the Future Skills that will be needed in highly emergent future contexts – including digital competences, but transcending them. This calls for new strategies and concepts concerning structural, teaching and learning aspects and a new way of embracing lifelong learning concepts. “Future organizations” have been identified that have already set out for dealing with those new demands. By learning about their innovative approaches concerning employees’ competence and skills acquisition, a veritable turn away from specialist knowledge and towards Future Skills can be observed – and cannot be ignored by higher education.Keywords: Future Skills, Higher Education, Learning, Competence, Delphi Survey, Education Research

Use of Artificial Intelligence to Predict University Dropout: A Quantitative Research
Authors: Agrusti Francesco , Bonavolonta Gianmarco , Mezzini Mauro
Published: February 2021

The main aim of the research is to predict, as early as possible, which student will drop out in the Higher Education (HE) context. Artificial Intelligence (AI) is used for replacing repetitive human activities, e.g. in the field of for autonomous driving or for the task of classification pictures. In these areas IA competes with the man with fairly satisfactory results and, in the case of college dropout, it is extremely unlikely that an experienced teacher can “predict” the student’s academic success based on only on data provided by administrative offices. In this study used administrative data of about 6,000 students enrolled in the Department of Education of the University of Roma Tre to train convolutive neural nets (RNC). The trained network provides a probabilistic indicating, for each student, the probability of abandonment. Then, the trained network provides a predictive model that predicts whether the student will dropout. The accuracy of the obtained deep learning models ranged from 67.1% for the first-year students up to 94.3% for the third-year students.

The coronavirus disease 2019 (COVID-19) have devastated the globe and continues to be a protracted saga. In the absence of specific efficacious medical remedies, efforts to encounter and contain this emerging virus concentrated on vaccine production. A plethora of novel vaccines has been under development by major companies in different countries. To date, around 60 vaccines are in clinical trials with many other ones continuously added to the evolving pipeline. The variety in their corresponding designed platform and phases, warrants to tackle and understand what is being presented in the literature and launched in the market. 

Thus, this study is intended to enlighten and educate the medical community by reviewing the different vaccine platforms, and briefly explaining their mechanism of action with an emphasis on those that reached most advanced stages.
Coadded Spectroscopic Stellar Parameters and Abundances from the LAMOST Low Resolution Survey

Published: February 2021

I combine duplicate spectroscopic stellar parameter estimates in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 6 Low Resolution Spectral Survey A, F, G, and K Type stellar parameter catalog. Combining repeat measurements results in a factor of two improvement in the precision of the spectroscopic stellar parameter estimates. Moreover, this trivializes the process of performing coordinate-based cross-matching with other catalogs. Similarly, I combine duplicate stellar abundance estimates for the Xiang et al. catalog which was produced using LAMOST Data Release 5 Low Resolution Spectral Survey data. These data have numerous applications in stellar, galactic, and exoplanet astronomy. The catalogs I produce are available as machine-readable tables at https://doi.org/10.7281/T1/QISGRU.

The dark matter halo masses of galaxies can be estimated from their stellar masses via abundance matching (AM). For both the Milky Way and M31, the AM mass is higher than the mass inferred from kinematics. The higher AM masses exacerbate the missing satellite problem. The difference is especially pronounced for M31, for which

The Xisha Islands are composed of the Yongle Islands and the Xuande Islands in Hainan province, China. It has one of the highest species diversities in the world and is also a typical oceanic distribution area of coral reefs globally. The ichthyofauna of the Xisha Islands were recorded by underwater visual census in May 2019 and July 2020. The survey data were combined with previous records of species into the checklist of the Xisha Islands presented herein. A total of 691 species belonging to 24 orders and 97 families was recorded. The major families were Labridae, Pomacentridae, Serranidae, Chaetodontidae, Hexanchidae, Lutjanidae, Scaridae, Gobiidae, Scorpaenidae, and Carangidae. In this study, the coral fish diversity index (CFDI) of six families (Chaetodontidae, Pomacanthidae, Pomacentridae, Labridae, Scaridae, and Acanthuridae) was 229, indicating 756 coral fishes. In terms of the IUCN Red List, one species is Critically Endangered (Glyphis gangeticus), six species are Endangered (Stegostoma fasciatum, Aetomylaeus maculatus, Aetomylaeus vespertilio, Epinephelus akaara, Cheilinusundulatus sp., and Xiphias gladius), 16 species are Vulnerable, and 13 species are Near Threatened in the Xisha Archipelago, so conservation should be strengthened in this area in the future.

One species is a new record for China (Dischistodus pseudochrysopoecilus) and 23 species are newly found in the Xisha Islands.

Bacon et le cercle de l’expérience
Authors: Peterschmitt Luc
Published: February 2021

Dans cet article, nous examinons pourquoi Bacon ne justifie pas réellement les modes de l’ experientia literata , sinon en donnant des exemples. Le problème est qu’il semble livrer le début de l’invention au hasard. Nous y voyons en réalité le signe du pragmatisme de Bacon. Dans l’ experientia literata , la raison est par principe écartée, puisqu’on s’avance en terrain inconnu. Cependant, Bacon considère que les procédures en sont efficaces, parce qu’elles sont déjà admises : elles ont déjà fait leurs preuves, de sorte que l’on sait déjà qu’il s’agit de pratiques fructueuses. C’est que cette experientia literata témoigne d’une forme de savoir sédimenté, une « expérience » commune dont chacun peut se servir. Si elle est efficace, c’est qu’en réalité, on ne part jamais de rien dans la recherche.
« Anti-Darwin »
Authors: Salanskis Emmanuel
Published: February 2021

Cet article vise à apporter un éclairage sur les trois textes de 1888 que Nietzsche a intitulés « Anti-Darwin », à savoir un paragraphe du Crépuscule des idoles et deux fragments posthumes. Mon objectif est plus précisément de comprendre pourquoi l’expression « Anti Darwin » apparaît seulement en 1888, sachant que Nietzsche avait déjà adressé des critiques au darwinisme dans son œuvre antérieure, mais sans recourir à cette formule spécifique. Ma thèse est que les trois textes « Anti-Darwin » font partie du projet de transvaluation générale des valeurs qui caractérise l’année 1888.

La Belgique entre la France et l’Allemagne
Authors: Bitsch Marie-Thérèse
Published: February 2021

Point de rencontre entre la France et l’Allemagne, la Belgique est un terrain parfois propice à la coopération économique et financière mais, plus souvent, un enjeu dans les rivalités politiques ou commerciales.

« Industrialisée à outrance » et densément peuplée, plaque tournante du commerce international, la Belgique apparaît comme un marché convoité où la France est menacée d’un « Sedan commercial » face à une Allemagne dont la pénétration pacifique ne cesse de progresser. Terre d’élection du libéralisme économique, elle devient le point d’ancrage de sociétés financières à vocation internationale qui drainent les capitaux français et allemands et permettent au Royaume de participer largement à l’expansion mondiale. Ces relations d’affaires entre les trois pays, exceptionnellement développées quoique marquées par certaines dissymétries, témoignent d’un cosmopolitisme économique et financier déjà vivace à la Belle Époque.

Pays neutre par la volonté des Puissances, la Belgique constitue un enjeu politique et stratégique, surtout après 1904-1905, lorsque les États garants de sa neutralité sont groupés en blocs antagonistes entre lesquels la tension monte. Alors que la France et l’Allemagne cherchent chacune à l’attirer dans son camp, en créant des solidarités de fait fondées sur des affinités culturelles, des sympathies politiques ou des intérêts convergents, le gouvernement belge s’efforce de tenir la balance égale entre ses deux voisins. Exercice délicat qui ne laisse à Bruxelles qu’un rôle politique limité sur la scène internationale. Pourtant, le 2 août 1914, la Belgique rejette, avec une grande fermeté, l’ultimatum allemand.

Published: February 2021

In this chapter, the authors study a weighted-((f / (r, s)), k)/ (m, n): G system. The system consists of mn components arranged in a matrix form and the system works if all the sub matrices of order (r, s), the total weight of the working components is greater than f and the total weight of the working components in the system is at least k. This chapter deals with the evaluation of fuzzy reliability and fuzzy mean time to failure of the considered system with the application of fuzzy universal generating function and fuzzy Rayleigh distribution. In this study, the authors formed some prepositions to understand the behaviour of the considered system with respect to different varying parameters and also present an illustrative example to understand them.
A Novel Entropy Measure for Interval-Valued Intuitionistic Fuzzy Set and Its Application to Failure Mode and Effect Analysis
Authors: Kumar Kamal , Mani Naveen , Sharma Amit , Bhardwaj Reeta
Published: February 2021

The failure mode and effect analysis (FMEA) is widely used an effective pre-accident risk assessment tool to identify, eliminate, and assess potential failure modes in different industries for enhancing the safety and reliability of systems, process, services, and products. Therefore, this chapter presents a new approach to rank the failure modes under the interval-valued intuitionistic fuzzy set (IVIFS). For this, a novel measure to measure the fuzziness known as entropy measure is proposed. Some properties and axiom definition of the proposed entropy measure have been presented to show the validity of it. Afterwards, the proposed entropy measure is utilized to obtain the weight of risk factor and developed an approach under the IVIFS environment to determine the risk priority order of failure modes. Finally, a real-life case of FMEA has been discussed to manifest the developed approach, and obtained results are compared with the results obtained by the existing methods for showing the feasibility and validity of the proposed approach.

The development of metal-matrix composites (MMCs) has mainly been driven by the growing needs of modern applications for lightweight materials yet strong enough to withstand high service loading. On the other hand, carbon nanotubes (CNTs) presenting excellent combination of mechanical and physical properties have already performed as an excellent strengthening to reinforce MMCs. In present study, an air induction furnace was used to fabricate aluminum-multiwall carbon nanotubes (Al-MWCNTs) composite. The process was benefited for better dispersion of the CNTs, which was validated during microscopic studies. Additionally, the mechanical properties were significantly augmented i.e., the yield strength from 64±3 to 115±2 MPa, the tensile strength from 82±2 to 125±3 MPa for matrix material and Al-CNTs composite, respectively. The structural analysis including, grain size, crystallite strain and dislocation density were investigated using X-ray diffraction to relate with the improvement in the properties.

Authors: Shakir Muhammad Fayzan , Tariq Asra
Published: February 2021

Polymer nano composites based on poly vinyl chloride matrix were fabricated using polyaniline (PANI) and graphene nano platelets (GNP) as electrically conductive nano filler for the application of electromagnetic interference (EMI) shielding. DC conductivity was first evaluated by using cyclic voltammetry and found an increasing trend of electrical conductivity as PANI and GNP was added in PVC matrix that confirms the formation of electrically conductive network structure. Dielectric properties like dielectric constant, dielectric loss and AC conductivity were evaluated in frequency range of 100 Hz to 3 MHz that gives basic prediction for EMI shielding effectiveness. Vector Network Analyzer (VNA) was used to assess EMI shielding properties using coaxial cable method in 11GHz to 20GHz range and it was found that a maximum of 29 dB shielding was archived with the incorporation of 15 wt% of PANI in PVC. This value increased to 56 dB as 5 wt% GNP added in PVC/PANI 15 wt% blend. Interaction of matrix with filler, nature of filler and dispersion of filler in matrix are the key parameters for achieving high shielding effectiveness.

The article aims to investigate the feasibility of oxidation protection imparted to C-103 Nb-based alloy by fused slurry silicide coating of R512E (60Si20Fe20Cr) carried out at lower temperature (1200 °C) for higher dwell time i.e. 12 hours. The findings reveal that the coating treated can impart sufficient oxidation resistance the alloy, which may withstand the desired application conditions wherein oxidation protection for smaller time period is needed. Moreover, this treatment is not found to deteriorate other mechanical properties of the alloy in 'As coated' condition.

Published: February 2021

High temperature applications of self-lubricated sliding surfaces have gained industrial importance during the recent years. One popular system is based on sintered Ni-Cr composites with addition of solid lubricants. In the present work these composites were prepared under controlled sintering conditions with different combinations of solid lubricants (MoS2, Ag and CaF2) at 1200 °C under flowing argon. The physical properties such as sintered density, relative density and porosity were studied. The microstructures and phase studies of the Ni-Cr based composites were conducted using SEM analysis while the hardness of the composites was measured by Vickers Micro Hardness Tester. The friction tests were conducted with ball on disc configuration following ASTM G-99-95a standard. The MoS2 solid lubricant provides best lubrication at room temperature which is demonstrated by a low friction coefficient compared to pure Ni-Cr composites. The SEM pictures of worn out tracks show solid debris distribution, and filling of pores with solid lubricant phases. The time taken for stabilization of friction coefficient also varies with the type of solid lubricant. Dual and multiple additions of solid lubricants are also able to reduce the friction of coefficient compared to pure Ni-Cr composite.
