On conceptual provisions of design standards for earthquake-resistant construction
Authors: Perelmuter Anatoly V. , Kabantsev Oleg V.
Published: December 2020

Introduction. The standards for earthquake-resistant construction have undergone three revisions over the past decade. Each new revision was accompanied by serious discussions. However, no fundamental changes were made to the planned level of seismic safety and methods of safety assurance. Today the scientific and technical level of these standards does not satisfy many specialists, that’s why the engineering community is considering the development of new generation standards. The overall purpose of the work is to focus the attention of specialists not so much on methodological issues of design, as on unresolved or underdeveloped issues. For some of them, solutions are presented that should be considered as the subject for discussion. Materials and methods. Analyses of the regulatory requirements for the means and methods of seismic protection, publications with proposed improvements, and a comparative analysis of regulatory documents of different countries were carried out. We also analyzed the experience of implementing regulatory requirements in software systems. Results. The importance of establishing a relationship between the limit states of structures and the categories of the technical state of facilities during and after seismic impacts was emphasized. The importance of formulating requirements for the analysis of buildings and structures, different levels of responsibility when checking their response to effects of earthquakes, having different recurrence, was also emphasized. We have formulated relevant recommendations that are offered as starting points of discussions. The need for more detailed regulation of the analysis in the time domain was highlighted. Problems were identified that need to be solved both with respect to the initial seismological information and with respect to draft strain diagrams describing the construction material. Considerations were provided on the set of requirements for the design of construction facilities according to the “building + base” pattern, boundary conditions for the considered part of the base and the recalculation of accelerograms in terms of their lower boundaries. Conclusions. Although the above considerations do not claim to be the final solution to these problems, they can serve as the basis for the development of a new generation of standards or as a material, which initiates relevant research and decision making.
The analysis of a free two-layer composite beamon the elastic foundation
Authors: Filatov Vladimir V. , Kuzhin Bulat F. , Thi Linh Quyen Hoang
Published: December 2020

Abstract

Introduction. This article offers a methodology for the analysis of a two-layer composite beam on an elastic foundation that represents a one-parameter Winkler model. The behaviour of two-layer beams is described by A.R. Rzhanitsyn in his theory of composite rods that have rigid transverse and elastic-yielding longitudinal connections between layers. The theory of composite rods allows to study the stress-strain state (SSS) of multilayer foundation beams, having a layer featuring low thermal conductivity, and perforated beams.

Materials and methods. However, analytical solutions to these problems involve certain difficulties; therefore, they are often inapplicable. We propose to apply a numerical method, a method of successive approximations (MSA), developed by professor R.F. Gabbasov at the Department of structural and theoretical mechanics of the Moscow State University of Civil Engineering. MSA has proven to be an effective and highly accurate method designated for analyzing static/dynamic loads, applied to beams, slabs and shells, and for making stability calculations. The difference-based variation of the MSA method has a number of advantages over difference equations of the “classical” finite difference method (FDM). The proposed methodology allows to take into account various types of boundary conditions without involving contour points. Сoncentrated forces, concentrated moments, and piecewise distributed loads can be taken into account as loading types.

The article describes a problem solving algorithm. The system of initial differential equations is solved using difference analogs. Typical difference equations for regular and boundary points are provided.

Results. The analysis of a composite free-lying beam on an elastic foundation illustrates the proposed approach. The qua-lity of the analysis results is controlled by performing a numerical study of the solution convergence using several nested meshes.

Conclusions. The proposed method can be used in the engineering practice of design organizations and the educational process of higher educational institutions training civil engineering specialists.
Knowledge Transfer About Earthquake Disaster Mitigation To Children Through TF-IDF
Authors: Umran Maria , Sarim Hafiz Mohd.
Published: December 2020

Abstract: Past observations during a disaster identify that when children are separated from parents, they suffer due to the inability to comprehend disaster mitigation concepts. This study proposes a process from the existing framework K-Nearest Neighbor (KNN) and Term Frequency - Inverse Document Frequency (TF-IDF) for extracting a large body of knowledge in the form of documents into simple words. Those simple words can be arranged into contextual lyrics utilizing an Artificial Intelligence lyrics generator and then orchestrated into a song using a music generator. The piece, which is the output of the proposed process, is utilized to transfer the knowledge about earthquake disaster mitigation to children. A quantitative analysis of questionnaires on students aged 9-10 in Banda Aceh shows the song's highly significant effect in transferring the knowledge about earthquake disaster mitigation to children.

Authors: Mardina Vivi , Yusof Faridah , Alam Md. Zahangir
Published: December 2020

Abstract: In this study, the kinetic of a thermo-stable extracellular protease produced by Bacillus licheniformis (ATCC 12759) cultured in skim latex serum fortified media was investigated. The enzyme was stable up to 65 oC after incubation for 60 min at pH 8. The Lineweaver-Burk exhibited vmax (maximum rate) of 37.037 U/mg min-1 and KM (Michaelis-Menten constant) of 8.519 mg/mL. The activation energy (Ea) of casein hydrolysis and temperature quotient (Q10) were found to be 4.098 kJ/mol and 1.038 - 1.034, respectively, at a temperature ranging from 35 oC to 65 oC. The results of the residual activity test allowed estimating activation energy for irreversible inactivation of the protease (denaturation) which was approximately Ea(d) = 62.097 kJ/mol. The thermodynamic parameters for the enzyme irreversible denaturation were as follow enthalpy (59.286 ≤ΔH*d≥ 59.535 kJ/mol), Gibbs free energy (97.375 ≤ ΔG*d≥ 93.774kJ/mol), and entropy (-122.797 ≤ ΔS*d≥ -101.992 kJ/mol). These thermodynamic parameters inferred that the thermo-stable proteases could be potentially important for industrial application, for example, in the detergent industries.Abstrak: Pada penelitian ini, kinetika protease ekstraseluler termo-stabil yang diproduksi oleh Bacillus licheniformis (ATCC 12759), yang dikultur dalam media yang diperkaya serum lateks skim diselidiki.

Satysfakcja z pracy i poczucie sensu pracy u więźniów
Authors: Lenart-Kłoś Katarzyna , Nowicka Justyna
Published: December 2020

Praca to jeden z najważniejszych czynników resocjalizacji. Rozwija i kształtuje właściwe prospołeczne postawy więźniów. Stanowi narzędzie reedukacji i działań na rzecz zapobiegania powrotności do przestępstwa. Wysoki poziom poczucia sensu pracy prowadzi do zwiększenia satysfakcji i zaangażowania więźniów. Pomaga również w odnalezieniu się na rynku pracy po zakończeniu odbywania kary pozbawienia wolności. W badaniach uczestniczyło 198 pracujących osadzonych przebywających w Areszcie Śledczym w Lublinie.  zastosowano kwestionariusz WAMI M. Steger’a, Skalę Satysfakcji z Pracy A. Zalewskiej oraz kwestionariusz autorski. Zbadano, czy istnieje związek między satysfakcją z pracy a poczuciem sensu pracy, a także jakie są deklaracje dotyczące zamiaru podjęcia pracy po odbyciu kary pozbawienia wolności. Więźniowie z wyższym osobistym poczuciem sensu pracy odczuwają większą satysfakcję z pracy, a także częściej chcą działać dla dobra społecznego, budują bardziej realistyczne plany wolnościowe, odczuwają mniejsze obawy przed odnalezieniem się na rynku pracy po zakończeniu odbywania kary. Odpłatność za pracę więźniów wpływa na poziom odczuwanej z niej satysfakcji. Wysokie poczucie sensu pracy i zadowolenia z możliwości jej wykonywania wśród pracujących więźniów są istotnym elementem warunkującym zaangażowanie osadzonych w proces resocjalizacji.

Znaczenie zasobów w przystosowaniu osobistym osób przyjmujących leki bez recepty
Authors: Modrzyński Robert , Radoń Aleksandra
Published: December 2020

Przyjmowanie leków bez recepty stało się w Polsce powszechnym zjawiskiem. Co piąta osoba używa ich niezgodnie z zaleceniami, niejednokrotnie przekraczając dopuszczalnedawki. Problem ten dotyczy różnych grup społecznych i zawodowych. Nie zawsze wiąże się to jednak z uzależnieniem i może doprowadzić do strat na wielu różnych obszarach. Bezwątpienia poszukiwanie psychologicznych powiązań, stanowiących o potrzebie sięgania po lekarstwa bez zalecenia lekarskiego staje się pierwszoplanowe. Teoria Zachowania Zasobów Stevana E. Hobfolla (COR) może stanowić alternatywną koncepcję rozumienia zjawiska używania leków bez recepty. Teoria ta opiera się na założeniu, że aktywność człowieka jest skoncentrowana na zdobywaniu, utrzymywaniu i ochronie zasobów. Ich zdobywanie lub utrata ma fundamentalne znaczenie dla jakości życia i stanowi źródło motywacji do określonego zachowania. Z perspektywy COR utrata zasobów lub brak możliwości ich pozyskania może tłumaczyć wysoki odsetek osób używających leki bez zalecenia lekarskiego. Głównym celem pracy jest uzyskanie odpowiedzi na pytanie, jakie funkcje spełnia dystrybucja zasobów w kształtowaniu przystosowania osobistego. Ponadto równie ważne jest rozstrzygnięcie, jakie istnieją zależności pomiędzy czynnikami psychospołecznymi a przystosowaniem osobistym u osób przyjmujących leki bez recepty.

Materiał i metody: Badania miały charakter poprzeczny. Zastosowano kwestionariuszowe badania 300 osób używających leki bez zalecenia lekarskiego. Wykorzystano do tego Kwestionariusz Oceny Zachowania Zasobów S.E. Hobfolla (COR-E), Test Zdań Niedokończonych (RISB) J. Rottera, Inwentarz Depresji Beck’a (BDI) oraz Wielowymiarową Skalę Spostrzegania Wsparcia Społecznego (MSPSS) G. Zimeta.

Wyniki: Modelowanie równań strukturalnych wskazało na przyczynową relację pomiędzy zyskiem w zasobach a przystosowaniem osobistym (p = 0,001) jak i utraty zasobów i przystosowania osobistego (p = 0,003). Powiększająca się pula posiadanych zasobów oraz mniejsze doświadczanie ich utraty są predyktorami przystosowania. Potwierdzona została hipoteza mówiąca, że proces pozytywnej adaptacji u osób przyjmujących leki bez recepty zależy od dystrybucji zasobów.

Wnioski: Osoby przyjmujące leki bez recepty w sytuacji doświadczania utraty zasobów przejawiają symptomy nieprzystosowania osobistego. Umiejętność właściwego przystosowania siędo zmieniających się warunków życia i radzenia sobie z problemami zależy przede wszystkim od możliwości pozyskiwania zasobów.
A "RADIAÇÃO" DE ALMAS, ESPÍRITOS E CABOCLOS EM ANDARAÍ, BAHIA
Authors: Pedreira Carolina
Published: December 2020

Esse artigo trata a “radiação” como processo gerador de continuidades e criador de vínculos entre pessoas e entidades – almas, espíritos e caboclos – em dois contextos: no jarê, nome que se dá ao candomblé de caboclo na região da Chapada Diamantina, Bahia, e no terno das almas, um ritual de lamentação conduzido ao longo da Quaresma. A partir de uma etnografia realizada na cidade de Andaraí, argumento que a experiência da “radiação”, muitas vezes definida como um estágio anterior à incorporação, também pode ser pensada como um modo de ser com essas entidades, que, como qualquer relação, demanda atenção, conhecimento e zelo.
A PASSAGEM DOS CABOCLOS. OU COMO OS CABOCLOS TOCAM
Authors: Siqueira Paula
Published: December 2020

Ao me concentrar inicialmente no estudo da ação feiticeira nos terreiros de candomblé do interior da Bahia, a experiência do dia a dia do trabalho de campo mostrou que, se a vivência feiticeira era de fato presente, ela estava profundamente vinculada com a relação íntima travada por humanos e seus caboclos. Por isso, neste artigo, procurei descrever o enredo feiticeiro como uma forma específica de composição – a captura por composição - dentre as várias outras composições incessantemente articuladas pelos mais diferentes seres no candomblé (seres humanos e caboclos, é claro, mas também por entidades espirituais diferentes, sejam elas santos ou exus). Pude assim acompanhar pessoas e seus caboclos, ambos dando passagem a outras entidades espirituais que, por sua vez, modularam o domínio dos primeiros, conjugando assim novas temporalidades e conhecimentos, com resultados sempre imprevisíveis.

Neuroinflammation plays an important role in brain damage after acute carbon monoxide poisoning (ACOP). The nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing (NLRP) 3 inflammasome triggers the activation of inflammatory caspases and maturation of interleukin (IL)-1β and -18, and has been linked to various human autoinflammatory and autoimmune diseases. In this study we investigated the effects of hyperbaric oxygen (HBO2) on NLRP3 inflammasome activation after ACOP. Mice were randomly divided into four groups: sham group (exposure to normobaric air – i.e., 21% O2 at 1 atmosphere absolute); HBO2-only group; CO + normobaric air group; and CO + HBO2 group. Cognitive function was evaluated with the Morris water maze; myelin injury was assessed by Fluoro-Myelin GreenTM fluorescent myelin staining and myelin basic protein (MBP) immunostaining; and mRNA and protein levels of NLRP3 inflammasome complex proteins were measured by quantitative real-time PCR and Western blot, respectively. Additionally, serum and brain levels of IL-1β and -18 and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase were determined by enzyme-linked immunosorbent assay. It was found that HBO2 improved learning and memory, and alleviated myelin injury in mice subjected to acute CO exposure. Furthermore, HBO2 decreased NLRP3, absent in melanoma 2 (AIM2), caspase-1, and apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain mRNA and protein levels, and reduced brain and serum concentrations of IL-1β and -18 and NADPH oxidase. These results indicate that HBO2 suppresses the inflammatory response after ACOP by blocking NLRP3 inflammasome activation, thereby alleviating cognitive deficits.

Iron rust was an iron oxide compound that was less attractive, dirty, brown in color, and could pollute the environment, causing water to turn brown. To minimize iron contamination, conversion was carried out into iron (III) sulfate which was useful as an adsorbent for textile dyes. The purpose of this study was to determine the effect of sulfuric acid concentration and volume of H2O2 10% used to convert iron rust into optimal iron (III) sulfate compounds. The method used was a laboratory experiment on a batch scale and the hydrate content in iron (III) sulfate was carried out by the gravimetric method and its ability as an adsorbent was carried out based on the adsorption of dyes using the spectrophotometric method. The results showed that a reactor filled with 3 grams of iron rust powder and 100 mL of sulfuric acid was stirred at 425 rpm at 80 0C for 30 minutes, added 15 ml 10% H2O2 followed by stirring and heating until the solution was saturated, cooled to form crystals. The crystalline yield in these conditions was the increase in sulfuric acid concentration which resulted in low process efficiency, namely 30.34% at 50% sulfuric acid concentration and 15 mL 10% H2O2. The addition of 10% H2O2 solution to 50 mL of 20% sulfuric acid solution and 3.0 grams of a carat as much as 5 mL-10 mL 10% H2O2 produced iron (III) sulfate with 26.53% process efficiency. Iron (III) sulfate is a white, light gray crystal with the chemical formula Fe2 (SO4)3.5 H2O which was a rhombic shaped crystal. and able to absorb the dye which showed that 1.0 g of iron (III) sulfate was able to absorb the highest amount of red dye in a volume of 100 mL of textile dye solution.

Mitral valve (MV) repair for mitral regurgitation (MR) due to posterior
leaflet (PL) prolapse is achieved nowadays with a great success rate and
a good survival, similar, in certain subgroups. In this paper, Sakaguchi
et al describe their results in two groups of patients with PL prolapse.
Some patients underwent resection (resection group) and others chordal
replacement with/out limited resection (respect group). Results were
similar in terms of survival and MR recurrence. Our goal is to
eliminate, as much as possible, MR when a patient with degenerative MR
is operated on. Reduction of the mitral orifice and consequently an
increase of the transmitral gradient is the rule. MV repair for
degenerative MR provides great results, but there is not a single
surgical technique. A close evaluation of the anatomical findings will
allow us to choose the best strategy for the individual patient. An open
mind is the most important characteristic that a surgeon should have to
repair a prolapsing PL without residual regurgitation and dangerous
gradients.

Some selected Ostrowski type inequalities and a connection with numerical integration are studied in this survey paper, which is dedicated to the memory of Professor D. S. Mitrinovic, who left us 25 years ago. His significant influence to the development of the theory of inequalities is briefly given in the first section of this paper. Beside some basic facts on quadrature formulas and an approach for estimating the error term using Ostrowski type inequalities and Peano kernel techniques, we give several examples of selected quadrature formulas and the corresponding inequalities, including the basic Ostrowski's inequality (1938), inequality of Milovanovic and Pecaric (1976) and its modications, inequality of Dragomir, Cerone and Roumeliotis (2000), symmetric inequality of Guessab and Schmeisser (2002) and asymmetric inequality of Franjic (2009), as well as four point symmetric inequalites by Alomari (2012) and a variant with double internal nodes given by Liu and Park (2017).
Experimental investigation of higher alcohols as self-rewetting fluids in closed loop pulsating heat pipes
Authors: Chidambaranathan Sriram , Rangaswamy Swaminathan
Published: December 2020

Heat recovery plays an important role in all energy systems. The dissipation of heat is drastically increasing due to the advancement of electronic components. To cool the electronic components many heat recovery devices are introduced and out of which heat pipes play an important role. Pulsating heat pipe is a new type of heat transfer device which was introduced by Akachi in mid-1990. It is used mainly in the cooling of electronic components because of its potential for removing high heat flux. An experimental study was made to investigate the heat transfer performance of pulsating heat pipe using self-rewetting fluids of high carbon alcohols. The latent heat of vaporization plays an important role in the heat transfer performance of pulsating heat pipe. It was observed that the high carbon alcohols showed a decrease in the latent heat of vaporization. The high carbon alcohols such as 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, and 1-octanol were mixed with the deionized water to form a self-rewetting fluid. These self-rewetting fluids showed a unique behavior due to the inverse Marangoni effect. It was observed that the lower thermal resistance and higher heat transfer coefficient was obtained, especially in the dilute aqueous solution of 1-octanol.
Experimental investigation of using graphene nanoplatelets and hybrid nanofluid as coolant in photovoltaic thermal systems
Authors: Alshikhi Omran , Kayfeci Muhammet
Published: December 2020

It is a common observation that the photovoltaic (PV) panel shows a compromised performance when its temperature rises. To handle the performance reduction, most PV panels are equipped with a thermal absorber for removing the solar cells? excessive heat with the help of a heat transfer fluid. The mentioned thermal absorber system is termed as PV thermal or simply PV/T. This study aims to experimentally investigate the effects of a graphene nanoplatelets nanofluid, distilled water, and hybrid nanofluid as transfer fluids in PV/T collectors. A hybrid nanofluid comprises Al2O3 and graphene nanoplatelets. An outdoor experimental set-up was installed and tested under the climatic conditions in Karabuk, Turkey, to measure the inlet as well as outlet PV/T fluid temperatures, ambient temperature with solar radiation, and surface temperatures of both PV/T collector and the PV panel. The mass percentage of the coolant fluids was 0.5% (by weight) and their flow rate was 0.5 Lpm. Results show that the graphene nanoplatelets nanofluid is the most effective fluid because it showed superior thermal efficiency among all the tested fluids. Adding a thermal unit to the PV/T unit increased the overall energy efficiency by 48.4%, 52%, and 56.1% using distilled water, hybrid nanofluid, and graphene nanofluid, respectively

Authors: Ponnusamy Sathyakala , Gangadharan Sundara , Kalaiarasu Balaji
Published: December 2020

This study investigates the hidden thermal losses of glass plate, collector plate, water pipe and storage tank of solar water heater in the process of energy conversion. The present non-conventional energy methods are insufficient, whereas the exergy analysis provides a remarkable solution. Thus, employing the exergy analysis, entropy generation, exergy destruction, and exergy efficiency of each subsystem of solar water heater are computed. The obtained results showed that the entropy generation and exergy destruction are high during the heat transfer in each subsystem. Henceforth, the existing solar water heater design is modified placing hexagonal honeycomb structure between the glass plate and the collector plate and also water pipe is insulated to trap huge amount of solar energy. The proposed design exhibits improved exergy efficiency when compared with the existing model, which enhances the performance of the system.
The Attitude of Soviet Security Organs to the Home Army (July 1944 – January 1945)
Authors: Rogut Dariusz
Published: December 2020

The article deals with the problem of relations between the Soviet State Security Organs and the Home Army, an underground Polish military organization, in the final period of the Second World War. The author concludes that the main tools for establishing the Communist dictatorship and suppressing Polish society were the NKVD, NKGB, and SMERSH. Repression was aimed at broad groups of Polish society (landlords, teachers, doctors, clergy, etc.) and at certain individuals who were considered by the Soviet leadership as dangerous, hostile, and threatening the new Communist authorities. According to some estimates, from January 1944 to the end of the 1940s, 80–100 thousand Poles were arrested in the territory of the Second Polish Republic, of whom several thousand were convicted (not counting Polish citizens of other nationalities). They were held in screening and filtration camps, camps for prisoners of war and internees, correctional labour camps and labour battalions of the NKVD-MVD. The arrests, internment, mass deportations and trials of this period contradicted the norms of international law and marked the beginning of the new, Soviet, period of occupation.
Soil Quality Assessment in Relation to Food Crop Productivity to Support Agribusiness-Based of Dry Land Management by Scoring of Soil Quality
Authors: M Rachman L
Published: December 2020

To support Indonesian’s food self-sufficiency program, more quantitative and accurate data are required on the character of soil data needed, which can be more easily understood, practical and suitable for crop selection as well as for the right fertilizer recommendations to support the agribusiness development, implementation and operation. The purpose of this research is to develop and assess soil quality in relation to the productivity of major food crops by using Soil Quality Score Plus (SQS Plus) to support agribusiness-based management of dry lands. The use of SQS for assessing soil quality in principle determines the weighted average score obtained from the score of each selected key parameter multiplied by its weight. The SQS for the 36 locations observed varies from 2.36 (low) to 4.12 (high). SQS Plus adds letter(s) after a score to indicate the limiting factor(s) of soil ecosystem. The most limiting factor is low carbon organic content (72.2 % from the 36 locations observed), followed by low P availability (58.3%), and low total organic N (41.7%). Data of correlation between SQS and crop productivity is not good as expected.  Crop growth and crop production are not only determined by soil quality and its limiting factors.

O uso da tecnologia de realidade aumentada em catálogos de produtos com acesso a partir de dispositivos móveis, em especial aqueles desenvolvidos em aplicativos, indica a necessidade da avaliação da qualidade da experiência de uso destes. Os processos de avaliação de tais aplicações fornecem subsídios para indicar o estado atual do uso dessa tecnologia e possíveis aprimoramentos. Assim, o objeto de análise deste artigo é um catálogo virtual de venda que possui uma área que utiliza realidade aumentada para disponibilizar um provador virtual: o aplicativo para iPhones X e Xs desenvolvido pela marca de óculos Warby Parker. A pesquisa busca, num primeiro momento, o referencial teórico de heurísticas de avaliação que possam ser utilizadas em casos de aplicativos que fazem uso de realidade aumentada para dispositivos móveis e sua utilização na avaliação do objeto em estudo. Em seguida, foi testada a percepção de qualidade do aplicativo e a relação da experiência deste com a realidade aumentada. Para tanto, adotou-se a técnica de observação sistemática da interação de vinte usuários pertencentes ao público pretendido pela marca, seguida de entrevistas. Dessa forma, a partir de um exemplo atual, buscou-se avaliar a experiência de uso com a realidade aumentada em catálogos para dispositivos móveis e recomendar quais procedimentos de avaliação são mais adequados para futuros testes. Destacou-se, ainda, quais as vantagens e fraquezas encontradas em cada técnica avaliativa. A pesquisa revelou que a realidade aumentada utilizada no aplicativo possui alto grau de qualidade mas, também, indicou uma relação entre a qualidade da experiência de uso do aplicativo e a impossibilidade da simulação do peso do objeto ou do conforto desse no rosto do usuário: este ponto foi indicado como problemático por usuários que já utilizam óculos de grau. Porém, também foi revelado que, nos usuários que efetivaram a compra pelo aplicativo, a realidade aumentada teve um peso de mais de 70% nessa decisão, indicando que um bom uso da tecnologia pode ajudar na decisão de compra.
Hibridismo de técnicas artesanais e tecnologias digitais no design gráfico contemporâneo
Authors: Nikolaus Simone Fernandes , Gisela Belluzzo de Campos
Published: December 2020

Esta investigação apresenta a discussão sobre a combinação de técnicas artesanais e tecnologias digitais – considerada como um processo híbrido – que surge como uma tendência na área do design gráfico brasileiro. A partir de recursos teóricos sobre técnicas, tecnologias, conceitos, fundamentos do design e metodologias projetuais aplicada no estudo de caso, observa-se que muitos designers recorrem ao uso de técnicas artesanais como recurso de criação diferenciado, que possibilita atingir maior qualidade conceitual nos projetos.

A fundamentação teórica desta pesquisa parte de algumas definições acerca do termo design e, mais precisamente, design gráfico a partir de Cardoso (2008) e Villas-Boas (2003). Na sequência, para definir os conceitos relacionados à produção de imagem, considera-se as articulações de Santaella (2001), assim como a discussão sobre o hibridismo aplicado ao campo da arte e do design, de acordo com as considerações de Couchot (2005), Moura (2005) e Paula (2012). Para compreender como ocorre o hibridismo ao longo do processo de criação, é apresentado uma investigação sobre métodos de projeto, a partir da metodologia projetual fundamentada por Munari (1998). Esta pesquisa apresenta também exemplos de processos híbridos, que envolvem técnicas artesanais mescladas às digitais de projetos do design gráfico brasileiro contemporâneo. Para um estudo mais detalhado sobre este tema, apresenta um estudo de caso de design brasileiro. Com isso, esta pesquisa se propõe a analisar e descrever a metodologia utilizada no projeto Paper Town, do designer gráfico Rafa Miqueleto, que apresenta o hibridismo da técnica artesanal de modelagem em papel com a tecnologia digital, relacionando-o aos fundamentos do design propostos por Lupton e Phillips (2008).

An Empirical Research on Pilgrims Wayfinding Satisfaction Study: A Consideration for Improving Wayfinding Experience in Al Masjid Al Haram
Authors: Basiouni Abdullah
Published: December 2020

Millions of Muslims visit Makkah Al-Mukarramah every year for Hajj and Umrah. It is a mandatory part of both Hajj and Umrah rituals to visit Al Masjid Al Haram for various activities. Huge crowds and lack of prominent wayfinding signs make Hajis spend more time inside Haram trying to find their way that too in a tense and panicky state of mind. This paper aims at assessing the gravity of wayfinding associated challenges faced by Hajis by applying the well-known Customer Satisfaction Model and proposing possible solutions to minimize potential adverse effects. Convenience sampling was used to collect the data from the proposed sample size of 2000 from various nationalities and regions. A total of 618 responses were received. The structural equation modeling (SEM) method was used for path analysis using AMOS 21 analytical tool and results revealed a reasonable fit between data collected and the model used: chi2 (485.95), chi2 / DF (3.77), RMSEA (0.07), CFI (0.92), and all values of Cronbach's alpha are greater than 0.78. The results substantiated that Hajis face problems in wayfinding inside Haram, which leads to Hajis finding it challenging to navigate in the Haram area. When the respondents were presented with alternative solutions to improve their wayfinding inside Haram, the results showed a statistically significant improvement in the satisfaction level.
ОСНОВЫ МЫСЛИТЕЛЬНОЙ ДЕЯТЕЛЬНОСТИ
Authors: Ашшурский Эмир
Published: December 2020

В данном теоретическом исследовании всесторонне рассмотрена качественно новая концепция человеческого мышления и памяти, основанная на принципах психоламаркизма, неовитализма и системно-эволюционной иерархии. Причем особая роль в этих процессах отводится гистоновым белкам и астроцитам. Кроме того, отдельной строкой сказано также и о труднообъянимых пока еще способностях некоторых земных уникумов к гиперкалькуляции и другим чудесным мнемоническим феноменам. Что же касается общего смысла статьи, то он состоит в неоднократно уже ранее озвученной и детально нами разобранной идее об очевидной неизбежности диктатуры разума.

Authors: Zakirov Aidar , Zaripova Aigul
Published: December 2020

This paper discusses the problem of a GR concept comprehensive perception within the framework of Russian political science. Some researchers believe that GR is a modern replacement for the classic term “lobbyism” and is not new. Others call it a new direction in corporate management. Still others believe that GR is a new approach to political management. However, it cannot be denied that this area is gaining weight, evolving, and forming a research conceptual model. In this paper, an analysis and assessment of existing approaches to the definition of the GR concept by Russian and foreign political scientists are carried out. An author's definition of GR was put forward based on an understanding of the main goal of interaction between business actors and public authorities. In particular, GR is understood as the activity of representatives of large business actors in building sustainable relations with government to achieve competitive advantages and create favorable conditions for their own economic activities.

Unrealism in russian prose of early 20th century
Authors: Astashchenko Elena V.
Published: December 2020

The aim of the article is to analyze the multilevel manifestation of the text modality - from grammatical to aesthetic and build a general concept of unrealism as a peripheral, but permanent, constant of the modernist era. However, the ubiquity and dominant delimitation, necessary of structures with conjunctions of unreal comparison, with the predominance of those derived from future forms over those derived from the imperfect, also serves to strengthen the independence of the artwork from social pressure. Subsequently, the characteristic structures of modernity, analogous to the European "future in the past", building an alternative reality, are supplanted by the imperative mood of the second person, with the illocutionary act of calling for a change in the existing reality, in the primitive vanguard and the third person with the "pust" particle [let] in the middle of the 20th century, gradually degenerating into the imperative mood with the "puskai" particle [May], whose motivating pathos is extremely low.
