Decentralized Cloud Storage Using Blockchain
Authors: Shalom G. Richa , Nirogi Ganesh Rohit
Published: September 2022

Abstract: Because of its accessibility and ease of use, cloud storage has become the most widely used type of storage on the market in recent years. However, the privacy and data security of cloud storage are at risk. The protection of data security and privacy is the main topic of this essay. We suggest a blockchain-based decentralised storage system. Since blockchain is a distributed peer-to-peer system, any processing node connected to the internet can join and build peers' networks, maximising resource usage. Blockchain protects data security. The user's file is encrypted and shared among a number of network peers in the proposed system utilising the IPFS (Interplanetary File System) protocol. Hashes are generated by IPFS. The path of the file is indicated by the hash value, which is kept on the blockchain. This project is focused on decentralised secure data storage, high data availability, and effective storage resource usage.

Strategic environmental assessment is an effective tool for improving the level of environmental safety in various areas. The purpose of the article is to identify and classify the main tasks of strategic environmental assessment in subsoil use, taking into account its role and functions in the subsoil management system, and to suggest ways to improve environmental safety in subsoil use by means of strategic environmental assessment. The materials for the article were the results of many years of authors' research on various aspects of the methodology for assessing the environmental safety of subsoil use and scientific source analysis. The main research methods were comparison, deduction, analysis, synthesis, and classification. The authors grouped the tools of the strategic environmental assessment into five main groups: analytical, organisational, scientific and technical, control and procedural, and media. Analysis of the legal framework determines the need to finalise the draft of the Subsoil Code to take into account the requirements of the Law of Ukraine "On Strategic Environmental Assessment" in the context of carrying out state examination and assessment of reserves and resources of minerals and establishing conditions for mineral raw materials, drafting industrial development (technological scheme) of the deposit. The classification of the tools of strategic environmental assessment in subsoil use is carried out. Analysis of draft legislation in the field of subsoil use shows positive changes in achieving sustainable development goals. Simultaneously, the authors identified some inconsistencies between different legislative acts and projects.

Authors: Brown Harry , Acosta Marina
Published: September 2022

El objetivo de esta investigación es caracterizar los colectivos que se movilizaron en las elecciones panameñas de 2019 en torno al hashtag #NoALaReelección. El marco conceptual articula los desarrollos teóricos de la sociología política con el estudio de las redes sociales digitales. Además de la revisión bibliográfica, la propuesta cuali-cuantitativa de la investigación es exploratoria y descriptiva. Dentro de los principales hallazgos destaca que hubo cinco grandes clusters que guiaron la conversación digital, aunque con escasa interacción entre ellos; que el hashtag fue la manifestación virtual de un actor político y no una expresión casual, espontánea y desorganizada; y que el movimiento anticorrupción que se generó se condice con el tipo “desde arriba”.
Three Scenarios of the Future of Work: Technological Unemployment, Compensation, Hollowing Out
Authors: CAMPA RICCARDO
Published: September 2022

This study compares the dominant narratives on the future of work. It shows that a paradigm shift is underway in the context of scenario analysis, as a consequence of the impetuous development of robotic and computer technologies. Near the two main traditions of thought, which respectively emphasize ‘technological unemployment’ and ‘compensation,’ a third vision of the future is emerging that examines trends and scenarios ignored by traditional economic theories. This third narrative places particular emphasis on the ‘hollowing out’ phenomenon. It states that automation will not cause the complete disappearance of work, but only of the average qualified one. In other words, in the absence of corrective interventions, the society of the future will be characterized by the presence of a minority of privileged citizens, who will be able to fully enjoy the fruits of automation, surrounded by a majority of citizens engaged in precarious and degrading jobs. This study shows that the third narrative is only relatively new. Socio-technical expectations went full circle, reviving a prognosis already present in Karl Marx’s works.

Authors: PAYÁ CASTIBLANQUE RAUL , BENEYTO CALATAYUD Pere
Published: September 2022

El presente da cuenta de una investigación sobre las desigualdades de género en las condiciones de trabajo, empleo y salud laboral, en base a la explotación de la Encuesta Nacional de Condiciones de Trabajo, realizada en 2015 por el Instituto Nacional de Seguridad e Higiene en el Trabajo, cuyos microdatos hemos analizado mediante modelos de regresión logística ajustados por situación familiar y niveles educativos y estratificados por situación ocupacional y sector de actividad. Los resultados obtenidos demuestran que las mujeres presentan mayor probabilidad de tener peores condiciones de empleo, mayor exposición a riesgos psicosociales y de sufrir mayor sintomatología psicosomática. Por contra, los hombres se encuentran más expuestos a riesgos físicos y químicos y con mayor probabilidad de sufrir lesiones, accidentes de trabajo y problemas auditivos. Identificadas las desigualdades de género, se proponen políticas públicas para proteger y mejorar la seguridad y salud de las mujeres trabajadoras.
Las “prácticas del retorno” en la desaparición de personas: la materialización más allá de la ausencia
Authors: CASADO NEIRA DAVID
Published: September 2022

En los casos de desapariciones humanas se abre un amplio campo de actuación de prácticas articuladas bajo la secuencia del “rastreo/prospección, búsqueda, localización e identificación” (“las prácticas del retorno”). Es difícil hablar de desapariciones sin las prácticas del retorno y de quien las lleva a cabo. Lo que queda tras la desaparición son los recuerdos, las emociones, las reclamaciones, las reivindicaciones y los duelos; pero también todo lo que material y sensitivamente que persiste. Aquí la desaparición se materializa en su forma más biotecnológica. La desaparición se ha redefinido como el producto de una incursión de diversas experticias a las que se han subyugado todas las demás.
Correlation of EFL learners’ metalinguistic knowledge and grammatical accuracy
Authors: Sanosi Abdulaziz B
Published: September 2022

Grammar teaching has been a topic of debate for a considerably long time. Researchers and teachers discussed the benefits and shortcomings of its explicit instruction, which entails students’ awareness of metalanguage. Although much research has investigated metalanguage, its effect on improving students’ grammatical accuracy is still an unresolved issue, and the research concerning it is relatively limited. Nevertheless, it is widely recognised that metalanguage is beneficial for grammar teaching. Responding to this research gap, the present study investigated the relationship between EFL students’ metalinguistic knowledge and their grammatical accuracy. The researcher adopted a descriptive quantitative research design where two tests were administered to undergraduate participants (n=124). The tests scores were analysed using the Blackboard item-analysis tool and SPSS software to generate statistical information regarding the participants’ scores. The study findings revealed a significant positive correlation between the scores. This correlation was moderate and occurred at the students’ overall score level. Moreover, the study revealed a proper level of metalinguistic knowledge that was not in perfect parallel with students’ grammatical accuracy. The generated findings can provide insightful implications for grammar teaching. This finding is significant for EFL teachers as it supports claims on the importance of explicit grammar instruction. It is also essential for learners as they can use metalanguage to develop their learning. Moreover, the study suggests areas that may be helpful for researchers to further explore the issue.

The material specification is one aspect of teaching English at a vocational high school. Materials should be well-prepared to facilitate and promote students’ comprehension of concepts. This study aimed to develop instructional reading materials for Palembang – Tourism-Destination that are valid, practical, and potentially effective for students enrolled in a Travel Agent Study Program at one vocational school in Palembang, South Sumatera Province, Indonesia. The product was developed to meet the students’ needs. This research was a developmental study, with research phases including design, evaluation, and revision phases. Questionnaires, interviews, and reading comprehension tests were used to collect data. The data were analyzed quantitatively and qualitatively. A formative evaluation was conducted to determine the product’s validity, practicality, and potential impact. Experts evaluated the content, media, and instructional design for validity. The results indicated that the established product was extremely valid, scored an average of 3.65 for all evaluated elements. Practicality was rated highly in one-to-one and small-group evaluations, with average scores of 3.55 and 3.35. The results of the field test showed that the established texts had a high potential for impact, as 79.16 percent of students earned the required passing grade. As a result, it is reasonable to assume that the established product can be used in the classroom as the product for reading.

Published: September 2022

Collaborative skills have been perceived as the most important skills by learners, instructors, and employers alike in comparison to communication and entrepreneurial skills. Despite its significant role in the workplace, many find that working together with others may complicate tasks due to limited background knowledge and problems with social dynamics. There has not been a single assessment created to assess online collaboration as an integrated performance during group-based tasks. The present study, therefore, attempts to examine learners’ online collaborative performance and the dimensions contributing to effective online collaboration at the tertiary level. A mixed-method research design was adopted using surveys and interviews. A number of 508 undergraduates from local universities were given a questionnaire inquiring about their online collaborative behaviour in group work, while 30 of them were interviewed. The findings indicated that the communication tools and technological facilities category were rated the highest in online collaborative performance, whereas sharing responsibilities was rated the highest in team dynamics. There was also a significant correlation between online collaborative performance and team dynamics. Interview responses showed that learners agreed that good communication, clear goals, and team commitment were important elements for successful online collaboration. Despite the potential to enhance students’ online collaborative performance, collaborative learning is demanding for learners and educators alike.

Published: September 2022

Evaluating the learning outcomes of a certain course implementation can improve the quality of education. This study is focused on Indonesian EFL undergraduates’ perceptions of the relationships between teacher performance, technological resources, online project-based learning (OPJBL), and ESP learning outcomes. Participants of the study have attended English for specific purposes (ESP) online courses during school closures due to Covid-19. A survey was addressed to 350 undergraduates after a one-semester implementation of the OPJBL. The students were requested to rate their perceptions on validated items using a 7-point Likert-type scale for the data collection. The data were modelled and computed through partial least square structural equation modelling (PLS-SEM). The main findings of the study revealed that teacher performance and technological resources were significant in predicting OPJBL. Similarly, OPJBL was found to play a significant role in affecting ESP learning outcomes. Teacher performance and technological resources were also correlated to ESP learning outcomes. Significant differences were found among students’ locations for all variables. The findings highlight the benefits of the SEM approach for establishing the proposed framework and assessing the links between variables concerning the OPJBL and learning outcomes.
Texts used in the English language arts classroom of an American Islamic school
Authors: Parlindungan Firman , Rodgers Adrian
Published: September 2022

In this article, we examine what texts were selected for use by a middle school language arts teacher working in an American Islamic school. The literature has found that schools play an important role in supporting immigrant students to navigate a new culture, especially by selecting and providing appropriate texts for learning. Since students’ interaction with texts can mediate knowledge and identity construction, what cultural information and whose culture is embedded in the texts matter for language learning. As such, we wondered what texts a teacher would use to bridge the minority culture of the students with the majority culture in which the students lived. One teacher’s language arts class with 20 students at one American Islamic school was observed for one academic quarter and then described using a case study method. We qualitatively analyzed classroom observations, field notes, teacher interviews, and teacher and student work samples. We found that the teacher was able to use both academic texts, virtual texts, and teacher-created documents to explore some of the issues that the students face on a daily basis. This study further adds to the existing knowledge that culturally relevant texts may mediate students’ understanding of the larger socio-historical contexts in which they reside including a chance to develop language skills necessary for communication and learning.
Investigating the sociological use of slang from a hearer-oriented perspective
Authors: Mahmud Masrizal , Sadli Muhammad , Sari Diana Fauzia
Published: September 2022

Numerous studies have investigated the importance of slang in linguistics in various media, including novels. The dominant works on this subject have focused solely on the structural explanation of slang, leaving out its sociological context and meaning. Given the nature of slang itself as a pure informal language, studies about the semantic meaning of slang must be essential. This research looked into the slang words and expressions in a true-crime novel entitled ‘Black Mass’ by Dick Lehr and Gerard O’Neill in 2000. The goal is to discover the semantic meaning of slang words and expressions in the novel using the qualitative method and Mattiello’s hearer-oriented (2008) theory as the underlying theory. We applied the documentary method to retrieve the data and further analyzed it using Miles et al.  (2014) theory. Heavily influenced by the setting of South Boston and its crimes, Black Mass data indicated that this novel’s slang is primarily attributed to freshness and novelty. Subsequently, we found evidence of the novel’s use of desire to impress and faddishness, playfulness and humor, and impertinence properties. Color and musicality are this novel’s least common categories of slang, with only four occurrences in the entire manuscript. Given that the novel’s literature cover is still scarce, it is hoped that these findings are helpful to those who are interested in studying and researching the semantic area.
Narrenworte spricht der Narr - Sprichwörter in Erasmus’ Lob der Torheit
Authors: Descœudres Claude-Eric
Published: September 2022

Michel de Montaigne, einer von vielen, die die Werke des Erasmus von Rotterdam in den nachfolgenden Jahrhunderten lasen, stellte sich als Kind vor, Erasmus habe selbst zu seinen Dienstboten in Sprichwörtern gesprochen. So erzählt er es in seinen Essays.
Sprichwörter sprechen unmittelbar zu uns, und wir sprechen sie nicht selten aus, ohne uns darüber im Klaren zu sein, woher sie stammen. Erasmus hat sich in jahrelanger Arbeit auf deren Spuren gemacht, ihre Herkunft erkundet und nach ihrer Bedeutung gefragt. Mit seinen „Adagia“ ist ein immenses Werk entstanden, das aus 4154 Einträgen besteht.
Auch Stultitia, die Göttin der Torheit, nutzt Sprichwörter, um sich verständlich zu machen. Hier werden erstmals sämtliche Sprichwörter zusammengetragen, die in Erasmusʼ unverwüstlichem Klassiker „Das Lob der Torheit“ von 1509 auftauchen.

Authors: Nouri Ali , Zandi Taleb , Etemadizade Hedayatollah
Published: September 2022

This study was conducted to examine the influence of access to and use of information and communication technology (ICT) on academic achievement and motivation. Data were collected from 300 students (12- to 16-year-old; 160 boys) from Sanandaj, Iran. The ICT Familiarity Questionnaire was used to assess the level of students’ access to and use of ICT at school and outside of school. Students’ Grade Point Average was considered as an indicator of academic achievement and their scores of Academic Motivation Scale as a measure of academic motivation. The findings revealed that students had more access to and use of ICT at home than school. The majority of participants reported that they used digital devices for the first time when they were between 7 and 10 years old. The students spent more time using the Internet outside of school during weekdays. They used digital devices more frequently for general than academic activities. The canonical analysis indicated that ICT-related factors are significantly correlated with academic performance. However, students’ access to and use of ICT at school was the most influential factors affecting academic achievement. Furthermore, access to ICT at school and using digital devices at an earlier age were the most contributing factors correlated with academic motivation.
Selecting the most informative set of the deep-ocean tsunami sensors based on the r-solution method

Published: September 2022

В данной работе начальная форма волны цунами (ниже именуемая источником цунами) представляется как решение обратной задачи математической физики на основе инверсии удаленных записей пришедшей волны, что позволяет детально изучить факторы, влияющие на результаты восстановления. Исследуемая задача является некорректной, что приводит к ожидаемой неустойчивости численного решения, существенно уменьшить которую позволяет регуляризация, основанная на методе усеченного сингулярного разложения (SVD) (далее метод r-решения). В рамках предложенного подхода на основе анализа распространения энергии олны предлагается методика выбора наиболее информативной части имеющейся системы наблюдения для реального события цунами на Соломоновых островах 6 февраля 2013 г. Метод может быть полезен при разработке новых систем мониторинга цунами.

A significant constituent element of tsunami forecasting is to gain some insight into an initial tsunami waveform (below referred to as a tsunami source). Representing a tsunami source as a solution to the inverse problem of mathematical physics based on the inversion of remote records of the incoming wave allows one in detail to study the factors affected the inversion results. The above issue is an ill-posed one that causes the expected instability of the numerical solution. The regularization based on the truncated singular value decomposition (SVD) method (below referred to as the r-solution method) allows one to avoid this obstacle. Within the method proposed, we offer the methodology for selecting the most informative set of the tsunami sensors for the case of the Solomon Islands Tsunami of February 6, 2013, as an example. The method can be used in designing a tsunami warning system.
On the Instability of Iodides of Heavy Main Group Atoms in their Higher Oxidation State
Authors: Chakkingal Parambil Priyakumari , Perumal Sathya S R R
Published: September 2022

Inert pair effect—the tendency of s orbital of heavy atoms to stay unreactive, is a consequence of relativistic contraction of the s orbitals. While the manifestations of this, on the reactivity depends on the nature of the substituents, this aspect is often overlooked. Divalent Pb prefers inorganic substituents, whereas tetravalent Pb prefers organic substituents. Among the inorganic substituents, again there are specific preferences—tetravalent Pb prefers F and Cl more than Br and I. It is as though the relativistic contraction of s orbital of Pb is more significant with Br and I substituents, than with Cl, F and alkyl substituents. Herein, we address the problem using molecular orbital approach. We explain why typical hypervalent systems, like 12-X-6, 10-X-5 (X is a heavy atom, the number preceding X is the number of valence electrons surrounding X, and the number after X is the coordination number) with less electronegative substituents carrying lone pair (such as Iodine), and Lewis octet molecules like PbI4 are unstable, but their dianions (14-X-6, 12-X-5, PbI42-) are not. For heavy atoms, the relativistic contraction of s orbital renders the antibonding combination of s with ligand orbitals (σ1*) very low-lying, making it a good acceptor of electrons. Thus compounds where σ1* is empty are kinetically unstable, when an electron donor with appropriate energy (such as lone pair on Iodine or bromine) is present in the vicinity. Donor-acceptor interaction between σ1* and the lone pair on I or Br (F and Cl lone pairs are energetically far away from σ1*) is responsible for the instability of such compounds. The kinetic stability of tetraalkyl lead compounds is due to the absence of lone pairs on the alkyl substituents. This work illustrates the key factor responsible for the instability of heavy element iodides and provides a molecular-level insight on extended solid-state structures via quasi-relativistic density functional computations.
Posthumous Repugnancy
Authors: Kultgen Benjamin
Published: September 2022

I argue that the possibility of posthumous harm ought to be rejected. My argument centers on a kind of repugnancy case involving posthumous harm. Supposing the existence of posthumous harm, a person whose wellbeing was extremely high while she was alive could incur small posthumous harms over a long enough period such that it is true of that person that she had a life not worth living. I respond to various objections and in the end conclude that rejecting posthumous harm is preferable to all other options.
An Insight into the Electronic, Optical and Transport Properties of a Half Heusler Alloy: NiVSi
Authors: Radouan Djelti , Anissa Besbes , Benaouda Bestani
Published: September 2022

The half-Heusler alloy NiVSi is investigated theoretically by using first-principles calculations based on the density functional theory (DFT). For a better description of the electronic properties, the TB-mBJ potential is used for exchange-correlation potential. The structural, electronic, magnetic, optical and thermoelectric properties was calculated by WIEN2k software. The negative cohesive and formation energies found reveal that the NiVSi is thermodynamically stable. Electronically, the NiVSi is a half-metal with an indirect band gap of 0.73 eV in the spin-down channel whereas the spin up channel is metallic. The total magnetic moment is of 1. Optically, the obtained high absorption coefficient in ultraviolet wavelength range, make the NiVSi useful as effective ultraviolet absorber. Thermoelectrically, a high figure of merit in the p- and n-type region was obtained, what makes this compound very functional for thermoelectric applications. The generation of a fully spin-polarized current make this compound unsuitable for spintronic applications at room temperature, a doping may be a satisfactory solution to improve this property.
Effect of the Relativistic Electron Beam on Propagating Whistler-Mode Wave for Ring Distribution in the Saturn Magnetosphere
Authors: Annex E.H. , Pandey Rama S. , Kumar Mukesh
Published: September 2022

Cassini and many investigators reported whistler chorus near Saturn equatorial plane moving outwards. Whistler can propagate when going to high latitude and can alter its characteristics while interacting resonantly with available energetic electrons. Here investigating wave for a relativistic beam of the electron. It is observed and reported by Cassini Magnetospheric Imaging Instrument (MIMI) that inward radial injection of highly energetic particles is most dominant in Saturn intrinsic magnetosphere. Within this paradigm, an empirical energy dispersion relation for propagated whistler-mode oscillations in quasi Saturn magnetospheric plasma from such a non-monotonous ringed distribution function has been established. The kinetic approach and method of characteristics methodologies were used in the computations, which have been shown to be the best for building perturbed plasma states. The perturbed distribution function was estimated using the unperturbed particle routes. The ring distribution function was used to construct an unexpected growth rate expression for relativistic plasma in the inner magnetosphere. The results from the Saturn magnetosphere have been calculated and interpreted using a range of parameters. Temperature heterogeneity was shown to be a significant source of free energy that aided the propagation of a whistler-mode wave. By raising the peak value, the bulk injection of energetic hot electron injection impacts the growth rate. Growth was also demonstrated to be accelerated when the propagation angle increased. The research contributes to a better understanding of the relationship between wave and particle emissions and VLF emissions on a large scale.
Interactions of Novel Phosphonium Dye with Lipid Bilayers: A Molecular Dynamics Study
Authors: Zhytniakivska Olga
Published: September 2022

In the present work the 100-ns molecular dynamics simulations (MD) were performed in the CHARMM36m force field using the GROMACS package to estimate the bilayer location and mechanisms of the interaction between the novel phosphonium dye TDV and the model lipid membranes composed of the phosphatidylcholine (PC) and its mixtures with cholesterol (Chol) or/and anionic phospholipid cardiolipin (CL). Varying the dye initial position relative to the membrane midplane, the dye relative orientation and the charge state of the TDV molecule it was found that the one charge form of TDV, which was initially translated to a distance of 20 Å from the membrane midplane along the bilayer normal, readily penetrates deeper into the membrane interior and remains within the lipid bilayer during the entire simulation time. It was revealed that the probe partitioning into the model membranes was accompanied by the reorientation of TDV molecule from perpendicular to nearly parallel to the membrane surface. The analysis of the MD simulation results showed that the lipid bilayer partitioning and location of the one charge form of TDV depend on the membrane composition. The dye binds more rapidly to the neat PC bilayer than to CL- and Chol-containing model membranes. It was found that in the neat PC and CL-containing membranes the one charge TDV resides at the level of carbonyl groups of lipids (the distances ~ 1.1 nm, 1.2 nm and 1.3 nm from the bilayer center for the PC, CL10 and CL20 lipid membranes, respectively), whereas in the Chol-containing membranes the probe is located at the level of glycerol moiety (~ 1.5 nm and 1.6 nm for the Chol30 and CL10/Chol30 lipid membranes, respectively). It was demonstrated that the dye partitioning into the lipid bilayer does not affect the membrane structural properties.

Published: September 2022

The level of development of modern nuclear technologies forms a request for the development of new branches of science. At the same time, chemical dosimetry methods are also being improved [1, 2]. The essence of such methods consists in the quantitative determination of the radiation-chemical damages to the molecules of a substance when it is exposed to ionizing radiation [3, 4]. Liquid and solid solutions of organic dyes have intense bands optical absorption and fluorescence in the visible region of the spectrum, which makes it possible to use them in dosimetry systems [5, 6]. The use of organic dyes makes it possible to determine the absorbed dose in the range from 10-6 to 104 M Rad [7, 8]. In this work, we studied the processes of interaction of gamma-ray and high-energy electron fluxes with an aqueous solution of the organic dye methyl orange (C14H14N3О3SNa) [9, 10]. The calculations and experiment were carried out on a resonant electron accelerator with energies up to 30 MeV. The electron beam energy was 15 MeV. A tungsten converter was used to generate gamma quanta. The thickness of the converter varied from 0 to 6 mm. We have developed a computer program in C++ to simulate the irradiation process. This program uses the Geant4 class library based on the Monte Carlo method and runs in multi-threaded mode. For calculations, the model “PhysicsList emstandard_opt3” was chosen as the most suitable one. The value of radiation damage per one incident electron and produced gamma-quantum is determined in the work. The simulation results are compared with experimental data. Based on the results obtained, conclusions were drawn about the main mechanisms leading to the decomposition of organic dye molecules, and methods for optimizing the experiment for further research were proposed.
Specific Features of the Simulation of the Particle Diffusion Processes in Spatially Periodic Fields
Authors: Аksenova Viktoriia Yu. , Marchenko Ivan G. , Marchenko Igor I.
Published: September 2022

This paper is devoted to the studies of the specific features of the simulation of the particle diffusion processes in space – periodic potentials using Langevin equations. Different methods used for the presetting of initial conditions and their effect on the obtained solutions have been analyzed. It is shown that the system is nonequilibrium for all the methods of the presetting of initial conditions during a certain time interval of ttrm. This interval is increased as 1/γ with a decrease in the friction coefficient. A reasonable description of the transient processes of particle transport and diffusion requires a preliminary system thermalization procedure. A new method of the presetting of initial conditions that provides the most accurate description of equilibrium system has been suggested. It consists in the generation of the initial particle coordinates and velocities that correspond to the equilibrium distribution of harmonic oscillators with a specified temperature. The use of such initial conditions enables the computations with a good accuracy using no thermalization procedure at T < 0.1. The classic method of the determination of diffusion coefficients D as a limit limt→ꝏ (σ2/t) has been analyzed. It was shown that the use of it for computer-aided calculations is limited by the restricted computational time. It results in that the computation of D under certain conditions becomes impossible. A new method was suggested for the determination of the diffusion coefficient using the linear approximation of the dependence of dispersion on time. This approximation can only be possible after the kinetic temperature attains its stationary value. The suggested method requires several orders of magnitude less time in comparison to the classic method. As a result, it enables the computation of the diffusion coefficient even in the cases of total previous failure. The obtained data are of great importance for correct simulation computations of diffusion processes and for the appropriate physical interpretations of obtained data.

CZTS is working as an absorber layer, ZnCdS as a buffer layer and ZnO as a window layer with back and front contacts. The Zn content was varied from 0% to 10% and bad gap was changed from 2.42 to 2.90 eV as described in the literature. The impact of this band gap variation has been observed on the performance of solar cell by using SCAPS-1D software. The efficiency was varied due to variation in bandgap of ZnCdS thin film layer. The simulation was carried out at 300K under A.M 1.5 G 1 Sun illumination. The energy bandgap diagram has been taken from SCAPS to explain the different parameters of solar cell. The effect of ZnCdS having different bandgap values was observed. Then the thickness of CZTS layer was varied to check its effect and hence at 3.0 um gave the imporved efficiency of 13.83% roundabout. After optimization of CZTS layer thickness, the effect of working temperature was examined on the performance of solar cell. The absorption coefficient variation from 1E+4 to 1E+9 cm-1 caused major effects on the characteristics parameters of solar cell along with on J-V characteristics and Quantum Efficiency curve. At 1E+9 cm-1 absorption coefficient the efficiency of solar cell boost up to 16.24%. This is the remarkable improvement in the efficiency of solar cell from 13.82% to 16.24%. After optimization of all parameters, simulation was run at 280K, having CZTS thickness of 3.5 um, with 10% content Zn in ZnCdS (2.90 eV), and absoption coefficient of 1E+9, the model efficiency reached up to 17.6% with Voc of 0.994 V, Jsc 26.1 mA/cm2 and Fill factor was 71.4%.

Bu çalışmanın amacı, Ankara’da yükseköğretimde turizm eğitimi alan öğrencilerin, Covid-19 sürecinde, uzaktan eğitime yönelik bakış açılarını değerlendirmektir. Bu amaç doğrultusunda; Ankara’da ön lisans, lisans ve lisansüstü düzeyinde turizm eğitimi alan 383 öğrenciye dört bölümden oluşan bir anket uygulanmıştır. Araştırma sonuçlarına göre öğrenciler, uzaktan eğitim konusunda bazı olumlu düşüncelere sahip olmalarına rağmen dersleri okula gelerek, yüz yüze takip etmek istemektedirler. Uzaktan eğitimin, sosyal ortamdan uzak kalma, teknik sorunlarla karşılaşma, eğitimci ile iletişimlerini zorlaştırma gibi sakıncaları olduğunu düşünmektedirler. Çalışmada ayrıca, turizm öğrencilerinin uzaktan eğitime bakış açılarının değerlendirmeye yönelik alt boyutlardan kullanılan teknoloji, sistem ve uygulamaların; yaş, program ve kurum türü değişkenlerine göre farklılık gösterdiği sonucuna ulaşılmıştır. Bununla birlikte öz yeterlilik alt boyutunun tüm değişkenlere göre farklılık gösterdiği bulunmuştur. Uzaktan turizm eğitimine yönelik bakış alt boyutunun ise, program türü, yaş ve cinsiyet değişkenlerine göre farklılık gösterdiği tespit edilmiştir. Analizlerde t testi, ANOVA ve Mann-Whitney U testi kullanılmıştır.
TALAK SURESİ 4. AYETTE GEÇEN “ADET GÖRMEMİŞ OLANLAR“ İFADESİNİN KAPSAMI ÜZERİNE BİR İNCELEME
Authors: CANPOLAT Orhan
Published: September 2022

İddet, evlilik akdinin boşanma, ölüm veya fesih nedeniyle sona ermesi halinde, kadının yeniden evlenebilmesi için beklemek zorunda olduğu süredir. İddet, Yüce Allah tarafından ayrıntılı bir şekilde Kur’an da belirlenmiştir. Bekleme müddeti evlilik akdinin sona ermesi gerekçesine bağlı olarak değişmektedir. Bu sebepler: Boşanma yoluyla ayrılan kadınlar, hamile kadınlar, adetten kesilen kadınlar, adet olmayan kadınlar ve kocası vefat eden kadınların bekleyecekleri iddet süreleridir. İddetin sadece hamileliğin tespiti ve nesebin karışmasını önleme amacıyla sınırlandırılması doğru olmaz. Çünkü bu konuda Kur’an’da ön görülen süreler dinin taabbüdî nitelikteki hükümlerindendir. Bu davranış, dini olduğu kadar fıtri ve insani bir davranış olup, bütün toplumlarda ve dinlerde rastlanan bir haldir.
Corporate Social Responsibility and Bank’s Performance under the Mediating Role of Customer Satisfaction and Bank Reputation
Authors: Nguyen Kim Quoc Trung
Published: September 2022

This paper aims to examine the indirect linkage between corporate social responsibility (CSR) and firm performance via the effects of customer satisfaction and bank reputation. The study applies Structural Equation Modelling (SEM) to a sample of top managers, finance managers, chief accountants, and employees in Vietnamese state-owned commercial banks. The findings explore the statistically significant effect of CSR on bank performance under the mediating role of customer satisfaction and bank reputation, which are not concerned by previous studies. Because CSR activities assist banks in maintaining their reputation by complying with a long-term commitment to stakeholders' interests and providing valuable customer benefits to increase their satisfaction. So, the research results show that customer satisfaction and the bank's reputation promote a positive relationship between CSR and bank performance. Doi: 10.28991/ESJ-2022-06-06-012 Full Text: PDF
Extraction of Choreography for Service robots from a Ningyo Joruri Acting script by associative model
Authors: Narita Masahiko
Published: September 2022

What we should do with service robots to attract people’s attention and communicate more smoothly? We are proceeding with the robot OSONO project, which is referring to Japanese Joruri puppets, with the theme of utilizing expressions that incorporate the "Performing arts and technology" that has been passed down through the ages. In this paper, we propose the associative model that clarifies the correspondence between Ningyo Joruri’s acting script of the performance, and the choreography, and its meaning. And using this method, we discover a number of choreographies that can be used for service robots from the performance record video. Then we will prototype robot OSONO2 and implement this choreography on it so that we confirm that it is possible to express typical poses and typical choreography comfortably by mainly static evaluation. As a result, a series of flows for extracting the choreography for service robots from the acting script / acting video will be established.

This paper intends to develop a model of Big Data Analytics (BDA) utilization in Indonesian context. This is important due to the lack of related research on what factors influencing company to adopt BDA as their strategic and somehow secret weapon to win in nowadays intensified competition among companies in industries. By the model, this paper aims to contribute additional knowledge on what factors influence company to adopt this emerging technology as part of their strategic action in winning the market. Thus, intended questionnaires are distributed to about 206 companies. However, only 124 responses can be gathered and proceed using Part-Least Square (PLS) Structural Equation Modeling (SEM) and TOE Framework by adopting SmartPLS 3.0. By processing those data, two significant insights can be generated. First, BDA adoption in Indonesia is mainly encouraged degree of technology savviness, organizational readiness, and better anticipating environmental changes. Second, Organization readiness is also influenced by technology savviness and environmental changes anticipation. the company needs to master its technology which in Indonesia, compatibility and relative advantage could be significant issue. Thus, for those who want to adopt this emerging technology need to develop technology savviness and organization readiness while anticipate environmental changes.
