Dünyada lojistiğin önemi her geçen gün daha da artmaktadır. Lojistik operasyonlarının bir parçası olan karayolu taşımacılık faaliyetleri kamyonet, kamyon ve çekici-yarı römork birleşimi araçlar ile yapılmaktadır. Bu araçlar istahap haddi ve yükleme alanı kapasitesinin fazla olması nedeni ile en yaygın kullanılan araçlar arasında yer almaktadır. İhtiyaçlar doğrultusunda karayollarında seyreden araç sayısının artması karayollarındaki kaza riskinin de artmasına neden olmaktadır. Son on yılda bazı ülkelerde karayolu güvenliğini iyileştirmede önemli ilerleme kaydedilmiş olsa da, genel küresel sonuçlar çok daha kötüdür ve küresel karayolu ölümleri ve yaralanmalarını önemli ölçüde azaltmak için acilen değişikliklere ihtiyaç vardır. Karayolu trafik kazaları, küresel olarak kaza sonucu ölümlerin ilk nedenini oluşturmaktadır. Karayolu trafik kazaları, her yıl 1,3 milyondan fazla ölümden sorumluyken, ölümcül olmayan yaralanmalara ilişkin tahminler 20 milyon ila 50 milyon arasında değişiyor. Otomobilin ağır yük taşıtına arkadan çarpması durumunda meydana gelen ölüm oranlarının düşürülmesi için Regülasyon 58.03 seviyesi yayınlanmıştır. Bu çalışmada, Regülasyon 58.03’e uygun arka koruma donanımı tasarımı sonlu elemanlar yöntemi ile analiz edilmiştir. Yapılan analiz çalışmaları sonucunda tasarımda dikkat edilmesi gereken kritik noktaları tespit edilmiş ve nihai tasarım 58.03’de belirtilen yeni test kuvvetlerine göre test edilerek uygunluğu ispatlanmıştır. Anahtar Kelimeler: Regülasyon 58.03, Trafik kazalarındaki ölüm oranları, Arka koruma donanımı

Published: January 2022

Aim: This study aims to evaluate the effect of quality in health standards implemented at health institutions on the motivation of healthcare professionals.Method: The universe of this study consists of 202 healthcare professionals working at the private Medicana Bahçelievler Hospital operating at European Side of Istanbul with the 898 approval number on the date of 12.03.2019. In this research, the responses of the participants for the questions of the questionnaire were analyzed by the use of AMOS 24.0, and SPSS for Windows 22.00 programs. The sub-dimensions of quality standards in health care services (QSH), and motivation of employees (ME), being the scales used in the research, were determined by exploratory factor analysis, and then the crosscheck of these dimensions was performed by confirmatory factor analysis. Thereafter, values of Cronbach’s alpha, being the reliability coefficient, and composite reliability, and convergence validity were calculated. The effect of quality standards in health care services (QSH) on the motivation of employees (ME) was examined through a structural equation model with implicit variables. And the comparison of all dimensions and sub-dimensions of the scales of quality standards in health care services (QSH), and motivation of employees (ME) as per demographic attributes was searched by one-way analysis of variance (ANOVA), independent samples t-tests.Results: As a result of the research, it has been observed that the quality standards in healthcare have a significant and positive effect on employee motivation. It was found that the managerial processes dimension of the quality standards in health affects the motivation of the employees in a significant and positive way by using only psychological and social tools, but the use of economic tools and organizational managerial tools among the motivation tools does not affect the motivation of the employee. However, it is seen that quality standards in health do not affect the dimension of educational processes by using psychological and social tools, which are motivational tools, and positively and significantly affect employee motivation by using economic and organizational-managerial tools.Conclusion: According to the demographic attributes of the participants of the research, it was determined that quality standards in health, and motivation of employees were being affected in a positive direction as their education and experiences increase. It was observed that the increase of the age of employees was positively affecting the managerial processes of quality standards in health, but that it wasn’t affecting their motivation. It was determined that the gender of employees wasn’t affecting the quality standards in health, and motivation of employees.

Authors: Tiznado-Granzotto Rodrigo
Published: January 2022

Los bosques pantanosos de la zona Centro - Sur de Chile se distribuyen entre las regiones de Coquimbo a Los Lagos (30°- 41°28´ S). Destacan en la región de La Araucanía los bosques pantanosos denominados Pitrantos, dominados por Blepharocalyx cruckshanksii y Myrceugenia exsucca. Actualmente, los pitrantos se encuentran bajo el permanente estrés de las actividades antrópicas y podrían convertirse en ecosistemas extintos antes de ser científicamente conocidos. El objetivo de este trabajo es caracterizar estructuralmente un bosque pantanoso sin intervención antrópica en la comuna de Pitrufquén, Chile. Para esto, se estableció en el área de estudio una parcela rectangular de 300 m2 en donde se registró la especie arbórea, se midió la altura y el DAP de todos los individuos de tipo latizal, se contó el número de brinzales de cada especie y, finalmente, se contabilizó el número de plántulas en 50 subparcelas de 1 m2, distribuidas dentro de la misma parcela de muestreo. El bosque pantanoso establecido en el sitio de estudio se encuentra conformado por nueve especies arbóreas, todas latifoliadas, perennifolias y nativas; la más abundante Myrceugenia exsucca con 11.928 individuos por hectárea; seguida por Drimys winteri con 5.952 individuos y alturas totales máximas de 20 y 18 metros, respectivamente. Posee una estructura típica en cuanto a la altitud y longitud en donde se establece, y se encuentra regenerando con especies propias a una avanzada dinámica sucesional.
Una mirada de la identidad del docente sobre la base de la práctica y el saber pedagógico en la disociación entre teoría y práctica
Authors: Pereira Ramírez Any Oliveth
Published: January 2022

A lo largo de la historia de la humanidad, estudiar a los sujetos desde distintas miradas ha sido el principal interés de las diferentes ciencias. En tal sentido, la pedagogía como disciplina tiene una gran misión: se trata de la formación del ser humano en su constante evolución. En favor de ello, el presente artículo tiene como finalidad estudiar la identidad del docente sobre la base de la práctica y el saber pedagógico en la disociación entre teoría y práctica. Es por ello que se empleó la investigación documental a fin de acceder a la literatura especializada y desarrollar una mirada crítica ante el objeto de estudio. A partir de allí se logra concluir que la identidad del docente es un proceso que se va edificando de manera paulatina desde las actuaciones pedagógicas. Igualmente, el formador va construyendo sus propios conocimientos, valores, creencias, actuaciones, impresiones y actitudes producto de la realidad que tiene próxima. Finalmente, la identidad del docente es un proceso único en cada pensador de la educación, que va a estar determinado por su propia trayectoria y oportunidades que tenga para desarrollarse como profesional y pensador de la educación a plenitud.

Published: January 2022

Antioxidant capacity of poorly soluble natural antioxidant kaempferol, in particular free or loaded in two types of cationic micelles, was studied on non-enzyme induced lipid peroxidation (LPO) in vitro. The micelles were based on triblock copolymers - poly(2-(dimethylamino)ethyl methacrylate-b-poly(propylene oxide)-b-poly(2-(dimethylamino)ethyl methacrylate (PDMAEMA-PPO-PDMAEMA) and poly(2-(dimethylamino)ethyl methacrylate-b-poly(ε-caprolactone)-b-poly(2-(dimethylamino)ethyl methacrylate (PDMAEMA-PCL-PDMAEMA). The lipid peroxidation was induced by incubating of rat liver microsomes with iron sulphate and ascorbic acid (Fe2+/AA). The effect of free and micellar kaempferol (at concentrations 25, 50 and 75 μg/ml) was assessed after 20 min incubation time. In the non-enzyme lipid peroxidation model, the kaempferol-loaded micelles significantly decreased the formation of malondialdehyde (MDA). The effect of kaempferol loaded in PDMAEMA-PCL-PDMAEMA micelles was more pronounced, showing an improved antioxidant activity in the conditions of oxidative stress and lipid peroxidation in vitro.
Obstacles sur le chemin de la psychothérapie pour les personnes âgées dépressives : un modèle d’accès en plusieurs phases
Authors: Falk Katrin , Kammerer Kerstin
Published: January 2022

Les maladies dépressives sont aussi répandues en Allemagne parmi les plus de 65 ans que parmi les populations plus jeunes, mais les personnes âgées font beaucoup plus rarement appel à un traitement psychothérapeutique que leurs cadets. L’étude Psychotherapie im Alter – Barrieren und Möglichkeiten des Zugangs (PSYTIA, « Psychothérapie et troisième âge – obstacles et possibilités d’accès ») examine, en Allemagne, à l’aide de méthodes de recherche qualitatives et quantitatives, quels sont les obstacles qui font hésiter les populations âgées atteintes d’une maladie dépressive à s’engager sur le chemin de la psychothérapie, et quelles sont les possibilités d’accès. Sur la base d’entretiens semi-directifs avec des personnes âgées dépressives (n = 18), des médecins généralistes (n = 14) et des psychothérapeutes (n = 11) de Berlin, nous avons reconstitué les étapes de l’accès à la psychothérapie dans son aspect social, un processus dans lequel différents acteurs jouent un rôle, chacun avec sa perception et sa conception propres. On peut distinguer quatre phases dans ce processus : 1. Le ou la patient(e) a besoin d’explications et de recevoir de l’aide (trouver un remède) ; 2. Il/elle envisage une psychothérapie ; 3. Il/elle cherche un psychothérapeute ; 4. Il/elle développe une relation psychothérapeutique bénéfique. La présente contribution révèle, pour chacune de ces phases, quels obstacles se dressent, quelles possibilités existent, et l’importance que cela revêt dans la décision des personnes âgées dépressives de faire appel à un traitement psychothérapeutique. Les résultats montrent qu’il est possible de faciliter l’accès de cette tranche d’âge à un traitement psychothérapeutique, tant à travers l’organisation générale qu’à travers le rôle de chacun des acteurs.

Published: January 2022

In the present paper we study the asymptotic behavior of discretized finite dimensional dynamical systems. We prove that under some discrete angle condition and under a Lojasiewicz's inequality condition, the solutions to an implicit scheme converge to equilibrium points. We also present some numerical simulations suggesting that our results may be extended under weaker assumptions or to infinite dimensional dynamical systems.

The slime mould algorithm (SMA) is a metaheuristic algorithm recently proposed, which is inspired by the oscillations of slime mould. Similar to other algorithms, SMA also has some disadvantages such as insufficient balance between exploration and exploitation, and easy to fall into local optimum. This paper, an improved SMA based on dominant swarm with adaptive t-distribution mutation (DTSMA) is proposed. In DTSMA, the dominant swarm is used improved the SMA's convergence speed, and the adaptive t-distribution mutation balances is used enhanced the exploration and exploitation ability. In addition, a new exploitation mechanism is hybridized to increase the diversity of populations. The performances of DTSMA are verified on CEC2019 functions and eight engineering design problems. The results show that for the CEC2019 functions, the DTSMA performances are best; for the engineering problems, DTSMA obtains better results than SMA and many algorithms in the literature when the constraints are satisfied. Furthermore, DTSMA is used to solve the inverse kinematics problem for a 7-DOF robot manipulator. The overall results show that DTSMA has a strong optimization ability. Therefore, the DTSMA is a promising metaheuristic optimization for global optimization problems.

Published: January 2022

This study focuses on the attitude control of a flexible spacecraft comprising rotating appendages, magnetic bearings, and a satellite platform capable of carrying flexible solar panels. The kinematic and dynamic models of the spacecraft were established using Lagrange methods to describe the translation and rotation of the spacecraft system and its connected components. A simplified model of the dynamics of a five-degrees-of-freedom (DOF) active magnetic bearing was developed using the equivalent stiffness and damping methods based on the magnetic gap variations in the magnetic bearing. Next, a fixed-time sliding mode control method was proposed for each component of the spacecraft to adjust the magnetic gap of the active magnetic bearing, realize a stable rotation of the flexible solar panels, obtain a high inertia for the appendage of the spacecraft, and accurately control the attitude. Finally, the numerical simulation results of the proposed fixed-time control method were compared with those of the proportional-derivative control method to demonstrate the superiority and effectiveness of the proposed control law.

Antimicrobials are therapeutic substances used to prevent or treat infections. Disinfectants are antimicrobial agents applied to non-living surfaces. Every year, several thousand tonnes of antimicrobials and their by-products are released into the environment and in particular into the aquatic environment. This type of xenobiotic has ecological consequences in the natural environment but also in technological environments such as wastewater treatment plants and methane fermentation sewage sludge treatment plants. The constant exposure of microbial communities not only to high concentrations but also to sub-inhibitory concentrations of antibiotics is a key element in the development of antibiotic resistance in aquatic environments and in soils. The future of antimicrobials lies in the development of biosourced or bioinspired molecules. The observation and deciphering of interactions between living organisms is the key to this development.
THERMAL PERFORMANCE OF FELT TYPE VEGETATED FACADE SYSTEMS IN A TEMPERATE CLIMATE DURING HEATING AND COOLING PERIODS
Authors: Yüksel Elif Özer , Türkeri Nil
Published: January 2022

Using vegetated facade systems (VFS) as a sustainable solution for existing and new buildings and evaluating thermal performance of these sytems are not a new concept. However, there is a gap in literature about measuring thermal performance of VFS applied on an insulated wall. Also, in the research literature, there are few studies measuring thermal performance of felt type VFS in temperate climates, and data about the thermal performance of VFS during winter periods is still scarce. Thus, the aim of the present study is to measure the thermal performance of a felt type VFS applied on a thermal insulated existing wall that us located in Kocaeli, Turkey, under Csa climate conditions during heating and cooling periods. Test results indicate that the felt type VFS acts as a shading device and has a positive contribution to the thermal performance of building walls during a cooling period. In daytime when there is a high amount of solar radiation, felt type VFS decreased exterior surface temperatures of the insulated existing wall by a maximum of 24.4°C, 32.2°C and 37.2°C, in spring, summer and fall periods, respectively. Additionally, indoor air temperatures of the vegetated facade were lower than indoor air temperatures of the reference facade with the maximum difference of 1.8°C during the cooling period. Also, test results indicate that the vegetated facade never dropped to below 0°C while exterior surface temperatures of the reference facade dropped below 0°C at nighttime in the winter period. Thus, it can be claimed that the felt type VFS behaves as a thermal buffer and enhances the thermal performance of the exterior wall of the existing building during heating periods at nighttime. As a conclusion, although differences between exterior surface temperatures of vegetated and reference walls were high, differences between interior surface temperatures of vegetated and reference walls were not meaningful. That is due to the fact that the existing building exterior wall assembly includes 5 cm thickness thermal insulation material which enhance the thermal performance of the brick wall. Finally, according to solar reflectance results, it can be claimed that vegetated facade systems have a positive effect on reducing urban heat island effect.

Pollution continues to be a menace affecting different aspects of life such as health, productivity, and comfort. This paper focuses on the elimination or reduction of sound pollution in buildings using cement-based boards made from pretreated coconut coir and oil palm fibers obtained from agricultural residues. The study includes an account of the preparation of fiber cement boards made from Portland cement Type 1, limestone powder, water, sand, and pretreated coconut coir and oil palm fibers at 5, 10, 15, and 20% by weight of powder materials, respectively, and a high-range water reducer in order to make sure that the natural materials would be spread in an even way throughout the specimens. Sound insulation tests were performed as key indicators of the performance of the fiber cement boards. It was found that an increase in the proportion of natural materials resulted in fiber cement boards with decreased density, compressive strength, and flexural strength. Furthermore, in relation to both physical and mechanical performance, the boards incorporating coconut fibers were superior to those incorporating oil palm fibers. With an increased proportion of natural fibers, sound insulation performance tended to improve. The boards prepared with coconut coir and oil palm fibers in this study yielded acceptable physical and mechanical properties and showed promise in relation to providing insulative protection against sound.
In a holistic perspective, time is absolute and relativity a direct consequence of the conservation of total energy
Authors: Suntola Tuomo
Published: January 2022

We are taught to think that the description of relativistic phenomena requires distorted time and distance. The message of this essay is that, in a holistic perspective, time and distance are universal coordinate quantities, and relativity is a direct consequence of the conservation
of energy. Instead of the kinematics/metrics-based approach of the theory of relativity, the dynamic universe (DU) approach starts from the dynamics of space as a whole and expresses relativity in terms of locally available energy instead of locally distorted time and distance. In such an
approach, e.g., the frequency of atomic clocks at different states of motion and gravitation is obtained from the quantum mechanical solution of the characteristic frequencies, and the unique status of the velocity of light becomes understood via its linkage to the rest of space. In the kinematic/metrics-based
theory of relativity, we postulate the principle of relativity, Lorentz covariance, the equivalence principle, the constancy of the speed of light, and the rest energy of mass objects. The conservation of momentum and energy is honored in local frames of reference, and time and distance are
parameters in frame-to-frame observations. In the dynamics-based DU, the whole space is studied as a closed energy system and the energy in local structures is derived conserving the overall energy balance. Any local state of motion and gravitation in space is related, through a system of
nested energy frames, to the state of rest in hypothetical homogeneous space, which serves as the universal frame of reference. Relativity of observations appears as a direct consequence of the overall energy balance and the linkage of local to the whole—with time and distance as universal
coordinate quantities. DU postulates spherically closed space and zero-energy balance of motion and gravitation. DU does not need the relativity principle or any other postulates of the theory of relativity. Primarily, the theory of relativity is an empirically driven mathematical description
of observations, with postulates formulated to support the mathematics. DU relies on mathematics built on the conservation of an overall zero-energy balance as the primary law of nature, which makes DU more like a metaphysically driven theory. Both approaches produce precise predictions. The
choice is philosophical—nature is not dependent on the way we describe it.

Adolescence is a period of transition, marked by habits that can influence the health of individuals in the long run. This study aimed to analyze the association between physical activity and food consumption in adolescents. This is a cross-sectional study with a probabilistic sample of 1.570 school adolescents from Montes Claros, MG, Brazil. The level of physical activity and consumption of fruits, vegetables, sweets, and soda/soft drinks was analyzed. Logistic regression was performed (significance level 5%). Among adolescents, 80.8% were classified as not active and practiced physical activity for at least 60 minutes in less than five days a week. In relation to food, 85.2% and 34.3% of adolescents reported consuming legumes and fruits less than three times a week, respectively. Consumption five times a week or more of treats was 64.1% and soft drinks 90.3%. Those who consumed fruit three times a week or less were 40% more likely to be less active. Those who consumed soda more than five times a week were twice as likely to be little active. Low levels of physical activity were associated with consumption of fruit less than or equal to three times a week and soft drinks greater than five times a week. There is a need to encourage the promotion of healthy lifestyle habits regarding the practice of physical activity and food consumption among adolescents, in school and family contexts.
Perceptions of Sri Lankan Seafarers about the Necessity of Ratifying the Ballast Water Management Convention in Sri Lanka
Authors: Kulathunga I. C. , Weerasena K. S. A.
Published: January 2022

The International Maritime Organization (IMO) developed and adopted the “International Convention for the Control and Management of Ships' Ballast Water and Sediments” (Ballast Water Management Convention or BWM Convention) in February 2004 to prevent the uptake or discharge of invasive alien species and harmful aquatic organisms and pathogens within ballast water and sediments [5]. The BWM Convention entered into force on the 08th of September 2017. In 2020, 85 countries have ratified the Convention, representing 91. 11 per cent of world merchant shipping tonnage [4]. Yet, Sri Lanka as a Flag State (FS) has still not ratified the BWM Convention [8]. This research explored the perception of the Sri Lankan seafarers about the necessity of ratifying the BWM Convention by Sri Lanka. The data for this qualitative/ quantitative study were gathered via interviews and questionnaires given to 80 merchant navy officers from both deck and engineering departments. Results of this study show that the Sri Lankan merchant navy officers bear the idea that Sri Lanka should ratify the BWM Convention as Sri Lankan waters receive ballast water from international vessels threatening the Sri Lankan marine ecosystems, economy and human health. Findings of the study revealed most of the Sri Lankan merchant navy officers have identified the need of ratifying the BWM Convention to preserve the coastal and marine environment and protect the endangered and indigenous aquatic species living in Sri Lankan waters. The respondents also viewed that Sri Lanka as a Port State (PS) should establish port reception facilities and provide training for port state control officers. Most of the merchant navy officers highlighted the need of a national policy framework strengthened by scientific research to address the issue. The financial incapacity to develop a task force and a national strategy, as well as the financial inability to develop scientific research skills and continuous monitoring & training were identified by the respondents as the main challenges to ratify the BWM Convention by Sri Lanka.

Recent advancements in microfluidics and high-throughput sequencing technologies have enabled recovery of paired H and L chains of Igs and VDJ and VJ chains of TCRs from thousands of single cells simultaneously in humans and mice. Despite rhesus macaques being one of the most well-studied model organisms for the human adaptive immune response, high-throughput single-cell immune repertoire sequencing assays are not yet available due to the complexity of these polyclonal receptors. We used custom primers that capture all known rhesus macaque Ig and TCR isotypes and chains that are fully compatible with a commercial solution for single-cell immune repertoire profiling. Using these rhesus-specific assays, we sequenced Ig and TCR repertoires in >60,000 cells from cryopreserved rhesus PBMCs, splenocytes, and FACS-sorted B and T cells. We were able to recover every Ig isotype and TCR chain, measure clonal expansion in proliferating T cells, and pair Ig and TCR repertoires with gene expression profiles of the same single cells. Our results establish the ability to perform high-throughput immune repertoire analysis in rhesus macaques at the single-cell level.

Immune response dysregulation plays a key role in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis. In this study, we evaluated immune and endothelial blood cell profiles of patients with coronavirus disease 2019 (COVID-19) to determine critical differences between those with mild, moderate, or severe COVID-19 using spectral flow cytometry. We examined a suite of immune phenotypes, including monocytes, T cells, NK cells, B cells, endothelial cells, and neutrophils, alongside surface and intracellular markers of activation. Our results showed progressive lymphopenia and depletion of T cell subsets (CD3+, CD4+, and CD8+) in patients with severe disease and a significant increase in the CD56+CD14+Ki67+IFN-γ+ monocyte population in patients with moderate and severe COVID-19 that has not been previously described. Enhanced circulating endothelial cells (CD45−CD31+CD34+CD146+), circulating endothelial progenitors (CD45−CD31+CD34+/−CD146−), and neutrophils (CD11b+CD66b+) were coevaluated for COVID-19 severity. Spearman correlation analysis demonstrated the synergism among age, obesity, and hypertension with upregulated CD56+ monocytes, endothelial cells, and decreased T cells that lead to severe outcomes of SARS-CoV-2 infection. Circulating monocytes and endothelial cells may represent important cellular markers for monitoring postacute sequelae and impacts of SARS-CoV-2 infection during convalescence and for their role in immune host defense in high-risk adults after vaccination.
Traditional Medicinal Plant Species Belonging to Fabaceae Family in Ethiopia: A Systematic Review
Authors: Asfaw Melese Mengistu , Abebe Firew Bekele
Published: January 2022

There are approximately 213 families of flowering plants in Ethiopia and among them 92 families contain species with medicinal properties. However, there is no compiled information that comprehensively expresses which plant species belong to each family. In the present review, a total of 127 medicinal plant species belonging to Fabaceae family and used to treat various human and livestock diseases were reported from 62 articles (53 published and 9 unpublished journals). Calpurnia aurea (26.7%) and Millettia ferruginea (11.8%) were among the most frequently cited species of Fabaceae followed by Trigonella foenumgraecum (11.02%). The highest numbers of species of Fabaceae (62 species) were reported from Southern Nation Nationalities Peoples (SNNP) region, and 58 species were from Oromia region. Regarding growth habit, the majority were shrubs (43 species) followed by tree (39 species) and herbs (38 species). The frequently used plant parts were leaves (19.7%) roots (17.3%) and the whole plant (16.5%). 40.5 % of the prepared medicinal plant remedies of Fabaceae were administered through the oral methods in different regions of the country. The most commonly treated health problems by species of Fabaceae were: snake bites (25 species), evil eye (19 species) and wounds (18 species) in various regions of the country. From the finding, it was concluded that Fabaceae family is providing a diverse medicinal plant species for the treatment of different human and livestock health care systems in Ethiopia. Thus, further research activities on phytochemical characterization and conservation would be suggested for better utilization from this family.
Faster point compression for elliptic curves of $j$-invariant $0$

Published: January 2022

Предлагается новый метод сжатия двух точек (до $2\lceil\log_2(q)\rceil + 4$ битов) для эллиптической кривой $E_b : y^2 = x^3 + b$ с $j$-инвариантом $0$ над конечным полем $\mathbb{F}_q$ при $q\equiv 1\pmod 3$. Точнее, получены простые явные формулы преобразования координат $x_0, y_0, x_1, y_1$ двух точек $P_0, P_1 \in E_b(\mathbb{F}_q)$ в два элемента $\mathbb{F}_q$, дополненные четырьмя битами. Для восстановления (на этапе разжатия) точек $P_0, P_1$ предлагается извлекать корень шестой степени $\sqrt[6]{Z} \in \mathbb{F}_q$ из некоторого элемента $Z \in \mathbb{F}_q$. Известно, что при $q\equiv 3\pmod 4$, $q\not\equiv 1\pmod {27}$ это можно сделать с использованием только одного возведения в степень в $\mathbb{F}_q$. Таким образом, новый метод сжатия оказывается значительно быстрее классического метода для координат $x_0, x_1$, в котором разжатие использует два возведения в степень в $\mathbb{F}_q$. Показано, что новый метод можно использовать для сжатия одной $\mathbb{F}_{q^2}$-точки на кривой $E_b$ с $b \in \mathbb{F}_{q^2}^*$.

Проверочные матрицы линейных кодов с максимальным расстоянием ($\mathrm{MDS}$-матрицы) - важный элемент современных криптографических примитивов, обеспечивающий наилучшее рассеивание входных битов. В ряде работ изучались способы построения и описания $\mathrm{MDS}$-матриц для использования в низкоресурсной криптографии. Однако мало внимания уделялось влиянию приводимости предлагаемых $\mathrm{MDS}$-матриц, которая может позволить злоумышленнику использовать наличие нетривиальных инвариантных подпространств у соответствующих преобразований. В данной статье предлагаются некоторые методы построения $\mathrm{MDS}$-матриц с примитивными характеристическими многочленами, имеющие повышенную стойкость по отношению к атакам, основанным на инвариантных подпространствах.
Context and Co-text in Bernard Ogini’s Hamlet for Pidgin (Oga Pikin)
Authors: Abonyi Odirin V.
Published: January 2022

This article examines a phenomenon that may trigger a resurgence in the pleasure of reading or watching performances of Shakespeare’s plays in Nigeria: adaptation and translation into Naija (previously Nigerian Pidgin). Specifically, it examines how the Naija translation Hamlet for Pidgin (Oga Pikin) is prototypical for such a revival. The study adopts a comparative approach and explicates how anaphoric reformulation (AR), cataphoric reformulation (CR) and exophoric reformulation (ER) condition the translation’s peculiar lexico-semantic choices in terms of borrowing, reduplicatives, calquing and the like. These forms enter a networked relationship within the co-text and context to bring about a contemporary equivalent to Hamlet. Readers and audiences extract meaning through clues such as collocation, background knowledge and other linking strategies provided consciously or unconsciously by the author/translator. The article concludes that this translation is also significant for its shift away from the cathartic effect of Shakespearean tragedy and towards a comic mode that has greater popular appeal.
