Experimental Study on the Flexural Behavior of Reinforced Polystyrene Blocks in Concrete Beams
Authors: Tat Lim Yong , Hua Ling Jen , Wei Lau Ji , Min Alicia Yik Yee
Published: May 2021

A new type of lightweight beam system was recently proposed by embedding polystyrene in beams to improve structural efficiency. This removes the non-performing concrete in the neutral axis and tension region to provide a comparable strength as a solid beam. There are, however, limited studies conducted to investigate the structural behavior of such beams. Therefore, this research presents an experimental investigation to assess the effect of polystyrene shapes in the beams. This involved testing a solid beam and five lightweight beams under flexural load using a four-point load test. The inclusion of polystyrene was estimated to have reduced the self-weight of beams by 8.6% to 11.8% when compared with the solid beam. The results also showed the ellipse polystyrene with a width of 70 mm and height of 50 mm produced the highest effective strength to weight ratio (sw) of 1.12 and performed 12% better than the solid beam. Moreover, the lightweight beams have more weight reduced than the strength, and those with ellipse polystyrene were found to have performed better than circular ones based on first crack load, ultimate load, and effective strength to weight ratio (sw). The beams with ellipse polystyrene allowed better stress distribution and this gave them a higher strength than sphere shape. For industry application, the polystyrene content is recommended to be greater than 10% while the effective strength to weight ratio (sw) of the beam is greater than 1. The successful reduction of the weight without affecting the structural performance has the ability to help in reducing construction costs.
The shared fish stocks conservation: revisiting the unconnected enforcement

Published: May 2021

“There is plenty of other fish in the sea," goes the old cliché as many stocks have been overfished by industrial fisheries, that the over-activity made some fish species in danger. The scope of this paper covers the enforcement issue of Southern Bluefin Tuna (SBT) as endangered fish species. Taking Indonesia, New Zealand, and Australia as member States who catch SBT, this paper is a conceptual study using content analysis aiming to review how these three-member States officially treat SBT stocks. Based on the discussion, it found that since the shared characteristic of SBT, in areas beyond national jurisdiction it might create regulatory gaps. While international provisions have been entered into force in respect of endangered fish stocks in high seas areas, however, a lacuna remained in which the law cannot reach the national fishing area. This situation may lead to a discrepancy framework at the national level. Therefore, this paper argues that connectivity is crucial to link enforcement among relevant States with the real interest. In this context, the enforcement must consider the movement path of SBT from a coastal State (the spawning ground), the flag State (the fishing vessel), and the Port State (the place to land SBT).

ANALISA BIAYA PEMANFAATAN FLY ASH SEBAGAI MATERIAL DASAR BETON SELF COMPACTING GEOPOLYMER
Authors: Chichilya S. P. Sondakh  , Stevanny Gumalang  , Mickson Pinori
Published: May 2021

Proses pemadatan dengan vibrasi untuk mendapatkan beton yang berkualitas memiliki kesulitan ketika diperhadapkan dengan model struktur yang kompleks. Sehingga beberapa dekade terakhir telah dilakukan penelitian dan pengembangan beton yang bisa memadat sendiri, yang dikenal dengan nama self-compacting concrete (SCC). Pengaplikasian SCC di Indonesia masih terbatas karena biaya pembuatannya yang cukup tinggi. Komposisi semen pada beton SCC lebih banyak dari beton konvensional yang artinya menimbulkan polusi udara lebih tinggi. Jumlah produksi semen berbanding lurus dengan jumlah CO2 yang dilepas ke atmosfer, maka industri semen dunia memberikan kontribusi besar terhadap emisi gas rumah kaca global. Beberapa penelitian mulai berinovasi mengkombinasikan SCC dan teknologi penggantian semen secara keseluruhan dengan material pozzolan yang memiliki karakteristik seperti semen. Salah satu alternatif material pengganti semen portland adalah fly ash yang merupakan material buangan pembakaran batu bara di PLTU. Agar Fly ash bisa mengikat seperti semen diperlukan aktivator. Campuran fly ash dan aktivator dikenal sebagai semen geopolimer, sehingga kombinasi dua teknologi beton ini disebut beton self compacting geopolymer dengan material dasar fly ash.  Di Indonesia, beton self compacting geopolymer masih terbatas dalam tahap pengujian mix design, sehingga penulis tertarik mengetahui tinjauan ekonomis beton jenis ini, dan bermaksud menganalisa biaya pembuatan beton self compacting geopolymer ini menggunakan material lokal, fly ash dari PLTU II Amurang, Sulawesi Utara. Penelitian dimulai dengan pemeriksaan material lokal di Sulawesi Utara untuk mencari mix-design beton. Dilanjutkan dengan melakukan pengujian experimental untuk mendapatkan karakteristik kelecakan beton segar dan kuat tekan beton. Selanjutnya dilakukan analisis biaya produksi berdasarkan mix-design per 1 m3 beton. Pengujian kelecakan dari pasta Beton Self Compacting Geopolymer dengan material dasar fly ash melalui metode slump flow,V-funnel test dan L-Box Shaped test menunjukkan bahwa sudah memenuhi syarat SCC juga menghasilkan beton mutu K-250. Beton geopolimer dikombinasikan dengan beton SCC yang biayanya memang sudah relatif tingi menghasilkan biaya pembuatan yang juga tinggi.

El Parnaso en exilio: Adaptaciones cinematográficas de la literatura uruguaya durante el periodo silente
Authors: Torello Georgina
Published: May 2021

En el periodo del cine silente, la adaptación de obras literarias es una de las maneras que el nuevo medio encuentra para legitimarse y, por supuesto, para abastecer de tramas a producciones que se consumen con gran rapidez en los países donde la industria florece. Latinoamérica también participa de estos pasajes intermediáticos, aunque en la mayoría de los casos lo hace precariamente. El presente artículo se ocupa de tres adaptaciones cinematográficas de textos literarios uruguayos realizadas en el exterior: Tabaré, de Juan Zorrilla de San Martín (Lezama y Canals de Homs, México, 1917), Los muertos, de Florencio Sánchez (Defilippis Novoa, Argentina, 1919) y Brenda, de Eduardo Acevedo Díaz (Martínez y Gunche, Argentina, 1921). Desde una perspectiva transnacional, se indaga en las zonas de tensión, alianzas y resistencias que esos cruces entre cine y literatura generaron en Uruguay. Se destaca que en todos los casos la recepción implicó una apropiación de esas obras extranjeras como nacionales o regionales, hecho que lleva a una redefinición de lo extranjero, asociado por lo general a la industria norteamericana.

Prensa y Estado en Cuba. Aproximaciones a un escenario en transición
Authors: Rodríguez Arechavaleta Carlos Manuel
Published: May 2021

El artículo aborda las dinámicas de cambio del periodismo actual en Cuba en estrecha conexión con las estrategias de rearticulación de la hegemonía ideológica del Estado. Basado en una investigación documental, analiza las condiciones específicas de esta relación dada la constante amenaza del gobierno norteamericano y los valores de la ideología socialista del régimen. Es fundamental abordar la emergencia del periodismo independiente on-line vinculado a la desprofesionalización del modelo de prensa socialista con orientación ideológica partidista, las políticas y condiciones de acceso a Internet y las estrategias de control y vigilancia del Estado. El factor distintivo parece ser la alta contingencia, la polarización ideológica y la radical confrontatividad entre el Estado y este emergente modelo de periodismo. No obstante, estas nuevas prácticas periodísticas, su cultura y percepción de roles, muestran una revalorización significativa del modelo de prensa ideológica partidista hacia un periodismo cívico que está contribuyendo de forma importante al desarrollo de una esfera de contención transnacional que potencia la deliberación sobre el futuro cubano.

Published: May 2021

On the basis of social learning theory, we explored the mechanism through which chief executive officers' use of the servant leadership style affects middle managers' voice behavior. We analyzed data obtained from a sample of managers of firms in the energy industry in China. We found
that chief executive officers' servant leadership had a positive influence on organizational collective promotion focus through its effects on top management team servant leadership. Further, organizational collective promotion focus was positively correlated with middle managers' voice behavior
through the mediator of middle managers' promotion focus. Finally, a promotion focus motivated middle managers to speak out more often in their organizations. Theoretical and managerial implications are discussed.

Successful production of healthy seedlings in a forest nursery can be ensured through seed treatment to enhance germination. This study assessed the effects of pre-sowing treatments on the germination of Jatropha curcas; to provide the best treatment for enhancing seedling production. The experiment was laid in a completely randomized design with four treatments: (i) control (T1), (ii) soaking in; water at room temperature at room temperature for 16 hours (iii) cow-dung slurry for 16 hours (iv) 98% concentrated sulphuric acid for 5 minutes Each treatment received 10 seeds and was replicated 5 times giving a total of 200 seeds sown in sterilized river bank sand. Germinated seeds were counted, converted to percentages and arsine values. The data were further subjected to analysis of variance and significant means were separated using Duncan multiple range test (DMRT) at 0.05 level of significance. The results showed that seeds with no pre-sowing treatment had the highest mean germination (66%), DMRT revealed that significant difference (P<0.05) existed between seeds with no pre-sowing treatment and other treatments. The study concluded that viable Jatropha curcas seeds have no germination problem; the seeds could be germinated without pre-sowing treatment.

Firewood serves as the principal source of energy for cooking and heating, for many rural communities, but the impact of firewood extraction on the forest is often undermined. The present study was undertaken to assess the firewood consumption pattern by households living near community forests of East Khasi Hills District, Meghalaya and the impact of such activity on species diversity and population structure on such forests. Data on firewood consumption and preferred firewood species, and impacts of firewood harvesting on species diversity and population structure were collected through household surveys and phytosociological studies respectively. The surveyed households showed high dependency on firewood and the consumption pattern varies with the family size. The preferred firewood species are those of hardwood trees such as Quercus spp., Lithocarpus spp., Castanopsis spp. and Myrica spp. Firewood extraction have negative impact on forests, resulting in decrease in species diversity and population of the preferred firewood species. Statistical analysis revealed that species richness and diversity and density differ significantly in protected and unprotected forests. Despite low per capita consumption of firewood and precautionary measures like regulated harvesting in the study area, firewood harvesting cannot be ignored as an important cause of forest degradation and biodiversity loss. More research into local ecological and cultural contexts and perceptions concerning costs and benefits can help devise sustainable management options, including alternative sources of fuel.

Published: May 2021

New changes to the school curriculum by enacting a minimum competency assessment (MCA) with PISA criteria in 2021 have led to confusion over the form of MCA questions among teachers and students due to limited learning resources at schools. This study aimed to produce valid and practical PISA COVID-19 mathematics tasks (PISAComat) potentially affecting mathematics literacy. This study involved 27 secondary-level students aged 15 years old with different levels of mathematics skills. Design research in the form of development studies was chosen as the core framework of this research assisted with the online learning platform. Data were analyzed descriptively through observations, tests, interviews, and document reviews. A set of PISAComat on quantity and change & relationship at the level of reasoning was gained after a formative evaluation. The formative process was conducted through zoom meetings and intensive communication at WhatsApp Group (WAG) to produce valid and practical PISAComat. After being tested in the classroom, the resulting PISAComat had been potentially effective in promoting students' mathematics literacy and life skills during the COVID-19 pandemic.

Published: May 2021

Background Fever in neutropenia (FN) remains a frequent complication in
pediatric patients undergoing chemotherapy for cancer. There are only
conflicting and weak recommendations for and against antibiotic
prophylaxis during chemotherapy. Procedure Pediatric patients were
observed in a prospective multicenter study (NCT02324231). A score
predicting the risk to develop FN with safety relevant events (SRE;
bacteremia, severe sepsis, intensive care unit admission, death) was
developed using multivariate mixed Poisson regression. Its predictive
performance was assessed by internal cross-validation and compared with
the performance of published rules. Results In 238 patients, 318 FN
episodes were recorded, including 53 (17%) with bacteremia and 68
(21%) with SRE. The risk prediction score used three variables:
chemotherapy intensity, time since diagnosis and type of malignancy. Its
cross-validated performance, assessed by the time needed to cover (TNC)
one event, exceeded the performance of published rules. Two clinically
useful score thresholds were found: a threshold of ≥11 resulted in 2.3%
time at risk and 4.1 months TNC; a threshold of ≥8 in 24.9% time at
risk and 12.1 months TNC. Using external information on efficacy and
timing of intermittent antibiotic prophylaxis, 4.3 months of prophylaxis
were needed to prevent one FN with bacteremia, and 5.2 months to prevent
one FN with SRE, using a threshold of ≥11. Conclusions This score, based
on three routinely accessible characteristics, accurately identifies
pediatric patients at risk to develop FN with SRE during chemothearpy.
The score can help to design clinical decision rules on targeted primary
antibiotic prophylaxis and corresponding efficacy studies.

Published: May 2021

This study presents the immunomodulatory potential of Abrus precatorius Linn. (Indian wild licorice) leaves. A hydroalcoholic extract of A. precatorius leaves (EAPL) was prepared by maceration. Thirty male mice were divided into five groups as follows: control group, model control group (cyclophosphamide-treated), and three treatment groups (treated with EAPL at doses of 100, 200 and 300 mg/kg, per os, daily for 14 days). Parameters, including hematological, biochemical, organ indices, hemagglutination test (HA titer), delayed-type hypersensitivity (DTH), interleukin-2 (IL-2) level, splenocyte proliferation and liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) analysis were evaluated. Histopathological examination was carried out for the spleen, kidney and liver. Cyclophosphamide (CPMD)-induced changes in white blood cells, lymphocytes and platelets were improved in the treatment groups. Total protein and albumin levels in the treatment groups were significantly higher. EAPL treatment significantly stimulated splenic T-lymphocytemediated proliferation. Neutrophil adhesion was insignificantly decreased in the model control group compared to the normal control group, which was slightly improved by EAPL treatment. EAPL treatment significantly improved the HA titer and cell-mediated immunity, which is an indication of antibody production. The IL-2 level was significantly higher in the treatment groups that received 200 and 300 mg/kg EAPL. LC-QTOF-MS analysis of EAPL showed the presence of flavonoids, lignans, iridoids and phenolic glycosides. These results suggest that A. precatorius leaves are a good candidate for a new immunomodulatory herbal formulation.
Thermoelectric generators
Authors: Patel Jay , Singh Manmohan
Published: May 2021

As the world is changing and developing with every passing day, the requirements of power are also increasing. There is a shift in utilizing the electrical energy as much as possible and for this reason, many countries have already made policies for completely ruling out the machines which don’t run on electricity. Apart from electricity, there are other forms of energy that can be used to convert that form into a more desirable form. For example, in a plant where the smoke comes out of the chimneys or in a car, the smoke carries a large amount of thermal energy with it. This energy is nothing but a waste and reduction in the efficiency of the systems. If somehow, this energy could be recovered, the efficiency can be increased. Thermoelectric generators serve for this purpose. Thermos electric generators get the heat and using the principle of heat conduction and p and n type materials, the heat can be directly converted into the electricity. There are many materials available in the market for p and n type but in our case, we chose silicon germanium which is also one of the most commonly used. First of all, a single module of thermoelectric generator will be made using p and n type material, as well as using conductive material and some ceramic substance. Then, the entire assembly will be made and this assembly will be exported to Ansys where custom materials will be added and applied on to the geometry. After performing analysis on full model, a comparative study will be presented in which the effect of material of conductive plate on to the voltage difference will be studied

Plasma streams flowing from space engines interact with other life-support systems of space stations, in particular with solar panels. The magneto-plasmadynamic motor is a source of rarefied low-temperature plasma and can be used in production of semiconductor devices, integrated circuits and in a number of other areas. At the same time, the optimization of such a plasma source involves the active use of electric probes for diagnosis of plasma formations. In the work the original methods for processing the probe experiments in plasma flows, including the use of flat and cylindrical oriented probes as well as the non-stationary probes, which allows expanding the capabilities of the probe method for plasma diagnostics, have been presented. The optimization of the probe measurement schemes has been discussed. The results of probe mea-surements in jets, both in the bench conditions and in conditions of the Earth’ ionosphere, have been presented. The study has been carried out using both full-scale and computational experi-ments. In the work the original methods for processing the probe experiments in plasma flows, including the use of flat and cylindrical oriented probes, as well as non-stationary probes, which allows expanding the capabilities of the probe method of plasma diagnostics, have been pre-sented. The studies have been carried out using the bench and computational schemes. The re-sults obtained are important for plasmadynamic technologies in microelectronics and for radio communication with spacecraft powered by plasmadynamic engines.

A turn from homogeneous to heterogeneous architectures permits to achieve the advantages of the efficiency, size, weight and power consumption, which is especially important for the built-in solutions. However, the development of the parallel software for heterogeneous computer systems is rather complex task due to the requirements of high efficiency, easy programming and the process of scaling. In the paper the efficiency of parallel-pipelined processing of video information in multiprocessor heterogeneous systems on a chip (SoC) such as DSP, GPU, ISP, VDP, VPU and others, has been investigated. A typical scheme of parallel-pipelined processing of video data using various accelerators has been presented. The scheme of the parallel-pipelined video data on heterogeneous SoC 1892VM248 has been developed. The methods of efficient parallel-pipelined processing of video data in heterogeneous computers (SoC), consisting of the operating system level, programming technologies level and the application level, have been proposed. A comparative analysis of the most common programming technologies, such as OpenCL, OpenMP, MPI, OpenAMP, has been performed. The analysis has shown that depend-ing on the device finite purpose two programming paradigms should be applied: based on OpenCL technology (for built-in system) and MPI technology (for inter-cell and inter processor interaction). The results obtained of the parallel-pipelined processing within the framework of the face recognition have confirmed the effectiveness of the chosen solutions.
Generalizations of regular and normal spaces II

Published: May 2021

A family m_X of subsets of a nonempty set X is called an m-structure. A set X with a topology_x001C_ and m-structure mX is called a mixed-space and is denoted by (X,tau,m_X). As a generalization of g-closed sets due to Levine, we introduce the notion of mg-closed sets in (X,tau,m_X). By using m_g-open sets, we define and investigate mixed-regularity and mixed-normality in (X,tau,m_X). As special cases, we obtain I_g-regular spaces and s-normal spaces.

Time as a Hidden Curriculum: Qualitative Study of Challenges Faced by Students with Mobility, Speech, and Visual Disabilities in P-12 Settings
Authors: Ressa Theodoto , Daniels Derek , Wells-jensen Sheri
Published: May 2021

Formal education is schedule driven yet time as a hidden curriculum pertaining to students with disabilities is understudied. The authors share different challenges around disability: The first author has a physical disability and is a wheelchair user and teaches disability and equity studies in education, the second author stutters and teaches speech-language pathology, and the third author is blind and is a white cane user and teaches linguistic and disability courses. Informed by personal and educational disability experiences, the authors examine three case scenarios related to the schooling of learners with mobility, speech, and visual disabilities in P-12 settings to understand the interaction of time and curriculum and the impact on their education. Since time as a hidden curriculum can be a barrier for students with physical, speech, and visual disabilities, then there is a need for the reconceptualization of time within the frame of curriculum development to genuinely support the schooling of students with disabilities.

Authors: Treer Tomislav
Published: May 2021

The aim of this research is to compare the average individual weight of the four most important fish species in fisheries (Cyprinus carpio, Silurus glanis, Esox lucius and Sander lucioperca), caught by angling in different parts of the Sava River catchment in Croatia. Significant differences were expressed between the counties along the Sava River catchment, with the smallest specimens (p˂0.05) caught in Vukovar-Sirmium county. Artisanal fishery is mostly developed in that part of the Sava River, along with angling in both countries – Croatia and Bosnia and Herzegovina. Furthermore, the inflow of the River Bosna passes through urban and industrial cities of Bosnia and Herzegovina. It can be concluded that implementing recreational fishing surveys with the specific aim of obtaining data on average individual weight is useful for fishery management.

The construction industry consumes a large quantity of cement, which therefore leads to a high CO2 emission due to the cement manufacture. The partial replacement of cement by supplementary cementations materials (SCMs) is considered as the most promising alternative to reduce the environmental impact of this industry. This investigation aims to evaluate the performance of calcinated clay (calcined bentonite at 850 °C) used as partial replacement of cement in cement-based mortar. The evaluated performances include the physico-chemical and mechanical properties, as well as microstructural characteristics.. Various characterization tests, including laser granulometry, X-ray diffraction (XRD), and X-ray fluorescence spectrometry (XRF) have been investigated. In addition, the hardened properties of different mortar mixtures were also investigated. Mortar mixtures incorporating different calcinated clay percentages corresponding to 8, 10, 12, and 14%, by mass of total binder content, were proportioned. Termogravimetric analysis (TGA) and its derivative (DTG), Differential scanning calorimetry (DSC), and microstructural (Scanning electron microscopy (SEM)) analysis were carried out on samples of mortar mixtures. Furthermore, the 28-d hardened properties were assessed to assess the pozzolanic activity of the investigated mixtures. Strength activity index (SAI), DSC, and TGA analyzes are presented. The obtained results showed that all the mixtures exhibited adequate pozzolanic activity conforming to the ASTM C618 specifications.

In this study, we will analyze the instantaneous control in the recruitment of civil servants in the Republic of Kosovo. The purpose of the study is to achieve knowledge of the object of study, ie how the procedure of recruitment of civil servants is carried out, which procedures should be implemented until the establishment of employment in the civil service of Kosovo and which bodies are competent to control the legality of administrative acts of state administration bodies in the field of recruitment and establishment of employment of civil servants. Specifically the detailed aspects of the facility, ie how the recruitment is performed, how a labor relationship is established in the civil service of Kosovo, and how the control is applied internal versus the legality of administrative acts of public administration bodies in the field of recruitment of civil servants and by whom. The result of this study is the achievement with the knowledge of the object of study. In this study to achieve or not to confirm the hypotheses raised, we have used descriptive and statistical methods. Primary data are taken from the annual reports of the Ministry of Public Administration on the state of the civil service, the work reports of the Independent Oversight Board for Civil Service, literature, legal acts, and general normative acts governing the field of recruitment in civil service. The conclusion of this study is that the staffs in the civil service are not accepted according to the principle of merit, that the state administration bodies largely respect the deadlines for the establishment of labor relations, that there is no instantaneous control in the field of recruitment of civil servants. Had the proper influence on the heads of state administration institutions to recruit civil servants on the basis of merit.

Chronic Hepatitis C virus (HCV) infection is defined as persistence of HCV RNA in the blood for more than six months. HCV is a major cause of chronic liver disease and cirrhosis. It’s serious public health problem, affects about 71 million people worldwide. HCV doesn’t destroy hepatocytes directly. It activates the host's innate and acquired immune system and causes liver injury indirectly. Behind hepatic, HCV can cause extra-hepatic manifestations. One of them is renal disease which can lead to end-stage renal disease, ESRD. The prevalence of HCV infection in patients on hemodialysis is high, ranging from 5% to 60%. HCV infection is a significant cause of morbidity and mortality in patients with ESRD on hemodialysis. In this review, we discuss HCV infection and chronic renal disease as comorbidities, their severity and outcome.

Published: May 2021

The socio-economic development of economic-territorial units subordinate to administrative-management institutions appears as one of the main tasks. The values of alternative indicators reflecting socio-economic development may differ, which makes it difficult to unambiguously assess the importance of the indicators. The applied available methods are either too receptive or does not provide sufficient accuracy. The proposed FARE-M methodology for determining the importance of indicators is the prolongation of the technique for establishing the importance of FARE (Factor Relationship) weights already used for research purposes. The employed technique is based on the internal balance of system elements that is the essential systemic feature. This allows, unlike in the case of the AHP method, the weights of the indicators to be determined with reference to the first row of the data matrix only.

Published: May 2021

The efficiency of the public finance system is conditioned also by the efficiency of public procurement processes. The Slovak healthcare system has been under pressure to increase long-term efficiency. With respect to achieve the efficiency in healthcare system, the efficient public procurement is necessary condition. It is important to examine the factors influencing the public procurement system in the health sector as well as the causal relationships that would provide a valuable platform for the evaluation mechanisms aimed at the effectiveness of the planned purchases. The healthcare sector is specific because it is difficult to consider the effectiveness of the medical equipment in public procurement as well as its long-term effects, the total cost of the treatment and the individual requirements of the patient. The aim of the study is to clarify, whether the use of GPA impact the occurrence of savings within the public procurement process and if application of GPA induces the competition among tenders, thus whether the use of GPA increase number of offers. We use data on public procurement in healthcare sector in Slovak republic in 2019. The focus of analysis is on the Agreement on Government Procurement use by Slovak public procurement bodies and its impact on competition and creation of savings in public procurement process. Our findings suggest that the use of Agreement on Government Procurement induce emergence of savings in public procurement and increases the level of competition. Analysis also indicates that there exists relatively tight correspondence between competition and emergence of savings within public procurement process. It holds that higher the number of offers is, the higher savings are.

Authors: Skorik Kseniya Vladimirovna
Published: May 2021

The research focuses on the problem of semiotic status of objects in the Anglo-Saxon and Russian charms. The text of charms is the object of the research. The aim of the research is to define the semiotic status of objects in the Anglo-Saxon and Russian charms and to reveal the functioning of the objects in the text of a charm. The work deals with charms as examples of a sacral text. The research is promising due to the fact that studying a sacral text in this context is based on the anthropocentric approach. The tasks of the research include the following: to denote the status of a charm as a sacral text, to describe the semiotic status of objects in a charm, to reveal the role of a ritual in the objects’ acquiring the features of signs, to define the functions of semiotic objects in the charms. The scientific novelty of the research is in its comparative analysis of Russian and Anglo-Saxon charms in terms of linguistic semiotics. The author points out and describes several functions of semiosis as a system of objects that have a semiotic status. The major conclusion made as a result of the research is that the symbolic functions of material cultural objects in a sacral text enable the objects to acquire various features when they are included in the ritual component of a charm.
