Methods to delineate membership in a ‘core’ community are inconsistent, rarely test the hypothesis of a ‘core’, and can mislead ecological analysis
Authors: Gans Maya , Custer Gordon , Diepen Linda van , Buerkle C. Alex
Published: June 2021

Community ecology includes linking variation in system functions to the
distribution and abundance of taxa. In inferring processes, functions,
and causal taxa, it is common practice to assume a core community can be
defined and that attributes of the core are representative of the entire
dataset. Assuming categorical thresholds in abundance exist has the
potential to be misleading, especially if rare taxa are contributing to
ecological processes. Additionally, there are no standard criteria for
core membership, complicating comparisons across studies. Rather, the
existence of a core set of taxa can be treated as a hypothesis that may
or may not be supported. We considered four methods commonly used for
defining a core in studies of microbiomes and applied them to two
published microbial data sets and simulations covering a range of
plausible communities. We evaluated the ability of each method to
correctly categorize taxa. Assignment of core taxa varied substantially
among methods and datasets. Additionally, the ability of evaluated
methods to capture the simulated core was contingent on the distribution
of taxon abundances. While able to correctly identify core taxa in
select cases, the methods disagreed more often than not. Given the lack
of agreement among core assignment methods, categorization of taxa into
sets corresponding to core and non-core is questionable and requires
testing and validation before use in any particular context. Our results
do not support applying methods of dimension reduction for core taxa
classification, but instead provide additional rationale to favor
analyses that use abundance data in their entirety.

A Comprehensive Review on Depression Detection using Computer Intelligence
Authors: Mahawar Hema , Verma Ravi , Agrawal Chetan
Published: June 2021

The depression that has affected millions of patients and their families in the last decade has been one of the most common diseases of mind. However, almost all methods of medicating anxiety depend on series of questions evaluations and professional judgments of depressive symptoms, which are highly reliant on doctors’ experience and time-consuming. The aim of our research is to create an objective and practical method for detecting depression in adolescents using facial characteristics. The majority of teenagers are wholly unaware that they have been depressed. Some teenagers hide their depression from others, whether they are even aware of it. An automated system is needed to select the teenagers who face depression. Various research projects aimed at identifying depression are explored in this article.

Solar photovoltaic (PV) systems have mainly been used in the past decade. Inverter-powered photovoltaic grid topologies are widely used to meet electricity demand and to integrate forms of renewable energy into power grids. Meeting the growing demand for electricity is a major challenge today. This paper provides a detailed overview of the topological trend of inverters with connection to the photovoltaic grid, as well as the advantages, disadvantages and main characteristics of the individual inverters. For proper integration into a network, coordination between the supporting devices used for reactive power compensation and their optimal reactive power capacity for grid current stability is important.

Authors:   LLC «NPF ELNAP», GORSHKOV Andrey V. , KOROLEV Ilya V. ,   NRU «MPEI», SHCHERBACHEVA Olga S. ,   NRU «MPEI»
Published: June 2021

An analysis of the current regulatory documents on electrical safety shows that the methodological guidelines for determining the induced voltage on disconnected overhead power lines (OHL) located near the operating OHL contain methodological and methodological errors. These errors can lead to a significant underestimation of the determined induced voltage. It has been established that the method specified in the regulatory documents for determining the maximum possible value of the induced voltage by means of a single measurement with subsequently multiplying the measured value by a certain recalculation factor k does not allow in principle to determine it reliably. To determine a reliable value at a certain point of the disconnected overhead line, in general, it is necessary to measure the induced voltage at the same point of the overhead line at different values of the currents affecting the overhead line. The article formulates the main and auxiliary tasks of determining the reliable values of the maximum possible induced voltage. The main principles of the methods for solving the stated tasks are considered.

There are many cases of incorrect work of relay protection due to the fact that most of the using devices are outdated. However, it is difficult to make a comprehensive replacement of all protections with modern ones due to the lack of funding and the high cost of modern devices. Therefore, an important task is to develop ways to solve this issue in the conditions of partial uncertainty of the initial information. An approach using game theory is considered that allows planning a reconstruction of relay protection with a limited budget and minimal risk. The choice of one of two variants for the reconstruction of the relay protection under conditions of uncertainty and lack of information is analyzed. When proving the options of reconstruction of relay protection, the most appropriate criteria were found to be the Hodges–Lehmann, Wald, and Bayes criteria. It is shown that the choice of the optimal strategy, taking into account the minimization of damage during the actions of relay protection, will allow to combine the indicators of reliability and efficiency when choosing the variant of reconstruction. The obtained results illustrate that this approach is promising for improving the reliability and correct distribution of budget funds during the reconstruction of substations.

Published: June 2021

The test section design of the TVS-MEI experimental setup intended for studying the hydrodynamics and heat transfer in a fuel assembly with micro fuel elements is developed, and the setup hydraulic circuit is modernized. The setup process characteristics correspond to the operational parameters of VVER-1000 reactor plants (a pressure up to 16 MPa and coolant temperature up to 350°C). The internal heat release in the bed of metal pebbles is obtained by high-frequency induction heating. A technology for compacting the test section made of high-strength alundum ceramics and a special clamping device for holding the bed were developed. The fuel assemblies with micro fuel elements have the outer geometrical parameters fully identical with those of the conventional assemblies with fuel rods. A technology for installing, wiring, and sealing thermocouples in the test section has been developed. Experimental studies aimed at determining the pressure loss and flow friction coefficient for a cylindrical pebble bed were carried with the following coolant operating parameters: P = (2--7) MPa and G = (0.05--0.5) kg/s. In processing the obtained experimental results, the dependences of pressure loss on the coolant mass velocity and the pebble bed flow friction on the Reynolds number were identified and plotted. The first experimental data on the temperature distribution in the pebble bed are obtained. The main objective of the experiments was to determine the possibility of heating the considered test section by using the chosen method.

Published: June 2021

Decisions made adopted in an enterprise power system in managing the electric energy consumption are analyzed. The urgency of the subject matter is stemming from the global-wide growth in the demand for electric energy and a systemic increase in the cost of energy resources. The study was carried out at an operating enterprise considered as an organizational and technical system. The subject area boundaries and the types of power engineering structures are determined at the enterprise. The system was decomposed into subsystems with identifying the applied organizational and technical managing/control actions. The power consumption management problem is formulated taking into account the minimization of financial costs, and its solution is found for one element. An algorithm for determining the optimal measure to be taken in the system is proposed, which offers a solution taking into account the specified criterion (financial expenditures for consumed electricity) and constraints (prototype functionality and energy payment budget). The algorithm checks the control actions in the course of system operation, which is the system lifecycle longest part. The structure of the decision making support system for managing the power consumption of an element is developed. The structure determines the sequence of measures to be taken in applying control actions with subsequently verifying the decisions made. Experimental studies were carried out on a system element, which that have demonstrated the practical applicability and financial savings, thereby testifying the possibility of further application of the study results in the power systems of enterprises belonging to all levels.

Deriving regional pedotransfer functions to estimate soil bulk density in Austria
Authors: Foldal Cecilie , Jandl Robert , Bohner Andreas , Berger Ambros
Published: June 2021

Soil bulk density is a required variable for quantifying stocks of elements in soils and is therefore instrumental for the evaluation of land-use related climate change mitigation measures. Our motivation was to derive a set of pedotransfer functions for soil bulk densities usable to accommodate different levels of data availabilities. We derived sets of linear equations for bulk density that are appropriate for different forms of land-use. After introducing uncertainty factors for measured parameters, we ran the linear models repeatedly in a Monte Carlo simulation in order to test the impact of inaccuracy. The reliability of the models was evaluated by a cross-validation. The single best predictor of soil bulk density is the content of soil organic carbon, yielding estimates with an adjusted R2 of approximately 0.5. A slight improvement of the estimate is possible when additionally, soil texture and soil depth are known. Residual analysis advocated the derivation of land-use specific models. Using transformed variables and assessing land-use specific pedotransfer functions, the determination coefficient (adjusted R2) of the multiple linear models ranged from 0.43 in cropland up to 0.65 for grassland soils. Compared to pedotransfer function, from the literature, the performance of the linear modes were similar but more accurate. Taking into account the likely inaccuracies when measuring soil organic carbon, the soil bulk density can be estimated with an accuracy of +/− 9 to 25% depending on land-use. We recommend measuring soil bulk density by standardized sampling of undisturbed soil cores, followed by post-processing of the samples in the lab by internationally harmonized protocols. Our pedotransfer functions are accurately and transparently presented, and derived from well-documented and high-quality soil data sets. We therefore consider them particularly useful in Austria, where the measured values for soil bulk densities are not available.

Published: June 2021

Objetivo: Explorar na literatura acerca do uso da videolaparoscopia (VLP) como intervenção no tratamento da apendicite aguda em gestantes e as possíveis implicações desse procedimento na saúde materna-fetal. Revisão bibliográfica: Verificou-se a predominância de vantagens na abordagem laparoscópica em comparação à apendicectomia aberta, uma vez que configura-se um método seguro e minimamente invasivo. Sendo uma técnica mais difundida atualmente, dados de pesquisas mais recentes sugerem que a técnica laparoscópica possui menor probabilidade de complicações, além de funcionar como um método não só diagnóstico como também terapêutico, que pode ser realizado em qualquer trimestre da gravidez. Algumas complicações como lesão ao útero gravídico, diminuição do fluxo sanguíneo uterino e eventos tromboembólicos para a gestante, bem como menor risco de depressão respiratória para o feto, foram evidenciadas. As diferenças entre as técnicas foram apresentadas, revelando um menor risco de hospitalização, infecções, irritação uterina, hemorragias, dor pós-operatória e íleo paralítico na cirurgia laparoscópica.  Considerações finais: A abordagem laparoscópica é mais segura que a apendicectomia aberta e deve ser considerada como procedimento padrão em pacientes grávidas.
Simplistic calculation of the tunneling splittings for proton transfer in malonaldehyde and formic acid dimer using the one-dimensional Schrödinger equation
Authors: Tikhonov Denis
Published: June 2021

In this manuscript we present an approach for computing tunneling splittings for large amplitude motions.

The core of the approach is a solution of an effective one-dimensional Schrödinger equation with an effective mass and an effective potential energy surface composed of electronic and harmonic zero-point vibrational energies of small amplitude motions in the molecule.

The method has been shown to work in cases of three model motions: nitrogen inversion in ammonia, single proton transfer in malonaldehyde, and double proton transfer in the formic acid dimer. In the current work we also investigate the performance of different DFT and post-Hartree-Fock methods for prediction of the proton transfer tunneling splittings, quality of the effective Schrödinger equation parameters upon the isotopic substitution, and possibility of a complete basis set (CBS) extrapolation for the resulting tunneling splittings.

Published: June 2021

Recent concurrent advances in methodology development, computer hardware and simulation software has transformed our ability to make practical, quantitative predictions of relative ligand binding affinities to guide rational drug design. In the past, these calculations have been hampered by the lack of affordable software with highly efficient implementations of state-of-the-art methods on specialized hardware such as graphical processing units, combined with the paucity of available workflows to streamline throughput for real-world industry applications. Herein we discuss recent methodology development, GPU-accelerated implementation, and workflow creation for alchemical free energy simulation methods in the AMBER Drug Discovery Boost (AMBER-DD Boost) package available as a patch to AMBER20. Among the methodological advances are 1) new methods for the treatment of softcore potentials that overcome long standing end-point catastrophe and softcore imbalance problems and enable single-step alchemical transformations between ligands, and 2) new adaptive enhanced sampling methods in the "alchemical" (or "λ") dimension to accelerate convergence and obtain high precision ligand binding affinity predictions, 3) robust network-wide analysis methods that include cycle closure and reference constraints and restraints, and 4) practical workflows that enable streamlined calculations on large datasets to be performed. Benchmark calculations on various systems demonstrate that these tools deliver an outstanding combination of accuracy and performance, resulting in reliable high-throughput binding affinity predictions at affordable cost.

Inverse Material Search and Synthesis Verification by Hand Drawings via Transfer Learning and Contour Detection
Authors: Serov Nikita , Vinogradov Vladimir
Published: June 2021

Nanomaterials of various morphologies and chemistry have an extensive use as photonic devices, advanced catalysts, sorbents for water purification, agrochemicals, platforms for drug delivery as well as imaging systems to name a few. However, search for synthesis routes giving custom nanomaterials for particular needs with the desired structure, shape, and size remains a challenge and is often implemented by manual research articles screening. Here, we develop for the first time scanning and transmission electron microscopy (SEM/TEM) reverse image search and hand drawing-based search via transfer learning (TL), namely, VGG16 convolutional neural network (CNN) repurposing for image features extraction and subsequent image similarity determination. Moreover, we demonstrate case use of this platform on calcium carbonate system, where sufficient amount of data was acquired by random high throughput multiparametric synthesis, as well as on Au nanoparticles (NPs) data extracted from the articles. This approach can be not only used for advanced nanomaterials search and synthesis procedure verification, but also can be further combined with machine learning (ML) solutions to provide data-driven novel nanomaterials discovery.
On-Surface Synthesis of Variable Bandgap Nanoporous Graphene
Authors: Wang Dingguan , Arramel Arramel , Lu Xuefeng , Ming Yang , Wu Jishan , Wee Andrew
Published: June 2021

Tuning the bandgap of nanoporous graphene is desirable for applications such as the charge transport layer in organic-hybrid devices. The holy grail in the field is the ability to synthesize 2D nanoporous graphene with variable pore sizes, and hence tuneable band gaps. Herein, we demonstrate the on-surface synthesis of nanoporous graphene with variable bandgaps. Two types of nanoporous graphene were synthesized via hierarchical C-C coupling, and verified by low-temperature scanning tunneling microscopy and non-contact atomic force microscopy with CO-terminated tip. Nanoporous graphene-1 is non-planar, and nanoporous graphene-2 is a single-atom thick planar sheet. Scanning tunneling spectroscopy measurements reveal that nanoporous graphene-2 has a bandgap of 3.8 eV, while nanoporous graphene-1 has a larger bandgap of 5.0 eV. Corroborated by first-principles calculations, we propose that the large bandgap opening is governed by the confinement of π-electrons induced by pore generation or the non-planar structure, and can be explained by Clar sextet theory. Our finding shows that by introducing nanopores, semimetallic graphene is converted into semiconducting nanoporous graphene-2 or insulating wide-bandgap nanoporous graphene-1.

Controllable fabrication of the enantiospecific molecular superlattices is a matter of imminent scientific and technological interest. Herein, we demonstrate that long-range superlattice chirality in molecular self-assemblies can be tailored by tuning the interplay of weak intermolecular non-covalent interactions. Different chiral recognition patterns are achieved in the two molecular self-assemblies comprised by two molecular enantiomers with identical steric conformations, derived from the hexaphenylbenzene – the smallest star-shaped polyphenylene. By means of high-resolution scanning tunneling microscopy measurements, we demonstrate that functionalization of star-shaped polyphenylene with fluorine (F) atoms leads to the formation of molecular self-assemblies with the distinct long-range chiral recognition patterns. We employed the density functional theory calculations to quantify F-mediated lone pair F ···π, C-H··· F, F···F interactions attributed to the tunable enantiospecific molecular self-organizations. Our findings underpin a viable route to tailor long-range chiral recognition patterns in supramolecular assemblies by engineering the weak non-covalent intermolecular interactions.

In this study, faceted mesocrystals have been assembled from the dispersion of truncated cubic-shaped iron oxide nanoparticles stabilized by oleic acid (OA) molecules using the non-solvent “gas phase diffusion technique” into an organic solvent. The effects of synthesis conditions as well as of the nanoparticle size and shape on the structure and morphogenesis of mesocrystals were examined. The interactions of OA capped iron oxide nanoparticles with solvent molecules were probed by analytical ultracentrifugation and double difference pair distribution function analysis. It was shown that the structure of the organic shell significantly depends on the nature and polarity of solvent molecules.
A multifaceted role of progranulin in regulating amyloid-beta dynamics and responses
Authors: Du Huan , Wong Man Ying , Zhang Tingting , Santos Mariela Nunez , Hsu Charlene , Zhang Junke , Yu Haiyuan , Luo Wenjie , Hu Fenghua
Published: June 2021

Haploinsufficiency of progranulin (PGRN) is a leading cause of frontotemporal lobar degeneration (FTLD). PGRN polymorphisms are associated with Alzheimer’s disease. PGRN is highly expressed in the microglia near Aβ plaques and influences plaque dynamics and microglial activation. However, the detailed mechanisms remain elusive. Here we report that PGRN deficiency reduces human APP and Aβ levels in the young male but not female mice. PGRN-deficient microglia exhibit increased expression of markers associated with microglial activation, including CD68, galectin-3, TREM2, and GPNMB, specifically near Aβ plaques. In addition, PGRN loss leads to up-regulation of lysosome proteins and an increase in the nuclear localization of TFE3, a transcription factor involved in lysosome biogenesis. Cultured PGRN-deficient microglia show enhanced nuclear translocation of TFE3 and inflammation in response to Aβ fibril treatment. Taken together, our data revealed a sex- and age-dependent effect of PGRN on APP metabolism and a role of PGRN in regulating lysosomal activities and inflammation in plaque-associated microglia.

Coisas do caminho: crédito, confiança e informação na economia do comércio de gado entre Viamão e Sorocaba (1780-1810)
Authors: Gil Tiago Luís
Published: June 2021

O objetivo principal deste livro é compreender uma economia dita “de Antigo Regime” a partir do estudo das formas como o crédito era praticado na dinâmica das relações pessoais, tendo como pano de fundo uma sociedade católica, corporativa, com uma hierarquia social baseada na política que incluía, no seu devido lugar, capitães, brigadeiros, pardos, donas, pretos, tenentes e forras. O contexto para isso é uma rota mercantil que interligava as localidades de Viamão e Sorocaba, passando por diversos outros lugares, mais ou menos importantes, como Vacaria, Lages, Lapa, Castro e Itapetininga. Uma rota comercial de um produto único, praticamente: os animais, especialmente mulas, cavalos e reses. Nesse sentido, falar de uma economia de Antigo Regime não é fazer desta definição uma simples forma de rotulagem. É preciso, antes, tomá-la em suas especificidades, procurando entender a originalidade de suas formas. Este trabalho é sobre os homens que faziam a rota das tropas e seus negócios. Procura entender como funcionava o acesso ao crédito, o crédito financeiro, mas também o crédito como sinônimo de confiança. E aqui entram todos: capitães, índios, criminosos, brigadeiros, conselheiros ultramarinos e secretários de estado e ultramar.

Metaforizando a encenação teatral, propõe visão ampla dos espaços em que o espetáculo se desenvolve distribuindo-se entre a platéia, bastidores e palco, suportes de estruturação da sua abordagem, que segue longo percurso e faz adequada seleção dos pontos de parada em que se detém. Diante do repertório crítico já considerável, que nas últimas décadas se desdobrou em centenas de artigos, ensaios e livros sobre a obra da escritora que examina, o autor segue, no entanto, uma via própria, ao desvendar territórios com um novo olhar, multiplicando as vias de acesso a essa obra e as possibilidades de diálogo entre áreas afins.
Nutrient criteria to achieve New Zealand’s riverine macroinvertebrate targets
Authors: Canning Adam D , Joy Michael , Death Russell G
Published: June 2021

Waterways worldwide are experiencing nutrient enrichment from population growth and intensive agriculture, and New Zealand is part of this global trend. Increasing fertilizer in New Zealand and intensive agriculture have driven substantial water quality declines over recent decades. A recent national directive has set environmental managers a range of riverine ecological targets, including three macroinvertebrate indicators, and requires nutrient criteria be set to support their achievement. To support these national aspirations, we use the minimization-of-mismatch analysis to derive potential nutrient criteria. Given that nutrient and macroinvertebrate monitoring often does not occur at the same sites, we compared nutrient criteria derived at sites where macroinvertebrates and nutrients are monitored concurrently with nutrient criteria derived at all macroinvertebrate monitoring sites and using modelled nutrients. To support all three macroinvertebrate targets, we suggest that suitable nutrient criteria would set median dissolved inorganic nitrogen concentrations at ~0.6 mg/L and median dissolved reactive phosphorus concentrations at ~0.02 mg/L. We recognize that deriving site-specific nutrient criteria requires the balancing of multiple values and consideration of multiple targets, and anticipate that criteria derived here will help and support these environmental goals.
NUANSA HEGEMONIS ASOSIATIF DALAM PENAMAAN KULINER MASYARAKAT URBAN SURABAYA

Published: June 2021

The purpose of this research is to describe the associative meaning that is formed from the culinary name in Surabaya and to describe the hegemonic nuances inherent in it. This type of research is descriptive qualitative, the data source is the Surabaya urban community and the data is in the form of culinary names that were created. Researchers use a data analyzing corpus. The naming of urban culinary is full of associative meanings that have different connotations from culinary names in the past, representing the psychic condition of the community because naming is a medium of language which is a reflection of the brain and soul of the wearer, the nuances of capital hegemony around class differences, exploitation and oppression. reflected in the names of foods consumed by the urban community in Surabaya in particular. A hegemonic society has not yet reached the point of becoming a survivor, still lamenting the fate and associative baper through the culinary names it created. Efforts to build the community's mentality so as not to continue to feel like a hegomonic victim can be started with the creation of optimistic culinary phrases or terms.

Foi aplicado questionário semiestruturado aos piscicultores e identificado por meio do licenciamento ambiental emitidos a distribuição na bacia, utilizou-se o método geoestatístico de krigagem para análise da concentração produtiva. A série temporal evidenciou aumento de tanques e área passando de 707 em 2008 para 2.441 em 2020. Quanto a instalação dos tanques 60% dos piscicultores utilizam área de pastagem e 40% área de Preservação Permanente. O sistema de cultivos mais empregados é o extensivo, com a criação predominante da espécie Colossoma macropomum, sendo o principal canal de escoamento o próprio Estado onde a produção é comercializada em feiras, mercados e frigoríficos.
Numerical Modeling of Unsaturated Soils Problems
Authors: Fredlund Murray D.
Published: June 2021

Numerical modeling (finite element analyses) of saturated-unsaturated soils problems generally involves the solution of linear or nonlinear partial differential equations, PDEs. The soil properties for unsaturated soils usually take on a functional form that subsequently requires an iterative procedure to obtain a solution. Special numerical solution techniques are helpful (and in some cases necessary) in order to have confidence that the results of the numerical solution are accurate. The dynamic upgrade of the finite element mesh (and time steps) during the iterative solution process have proven to be of significant value in ensuring the proper convergence of the numerical solution. The unsaturated soil property functions are usually obtained through use of estimation procedures based on the measurement of the soil-water characteristic curve, SWCC. One or more estimation procedures have been proposed in the research literature for soil property functions for each physical process of interest in unsaturated soil mechanics. The numerical modeller must be aware of the relationship between the estimated soil property functions and the solution technique. Boundary conditions required when solving unsaturated soils problems often involve the assessment of moisture and thermal flux conditions computed from meteorological records. There are conditions and requirements that must be quantifiable when solving unsaturated soils problems. The estimation of the unsaturated soil property functions makes the solution of unsaturated soils problems more complex than those of saturated soils.
Bilmecelerde metaforik dil üzerine
Authors: KUYMA Erol
Published: June 2021

İnsan, sosyal bir varlık olarak çevresi ile sürekli etkileşim halindedir. Bu etkileşim; davranışlara, bilişsel sürece ve iletişimin merkezinde yer alan dile de yansımaktadır. Sosyal hayatta edinilen deneyimler, bilişsel şemalar aracılığıyla yeni öğrenmelere ve anlamlandırmalara kapı aralar. Sözlü kültür ürünü olan bilmeceler de halkın duygu, düşünce ve deneyimlerinden izler taşıyan, kalıplaşmış sözlerdir. Bazı bilmece örneklerinde görülen metaforik yapı, bilmeceyi oluşturan bilişsel süreci ve temel düşünceyi de göstermektedir. Bu yönüyle bilmeceler, toplumsal bilincin söyleme dönüştüğü metaforik dil örnekleridir. Bu çalışmada, konularına göre sınıflandırılmış bilmece örneklerinden yola çıkılarak bilmecelerdeki metaforik yapı tespit edilmeye çalışılmıştır. Bilmecenin karşılığı ile soru kısmı arasında kavramsal düzeyde gerçekleşen aktarımlar, bireysel ve toplumsal deneyimleri gösteren metaforları işaret etmektedir. Kavramsal haritalama, kaynak alanı oluşturan soru kısmı ile hedef alanı oluşturan cevap kısmı arasında gerçekleşmektedir. İki alan arasındaki ontolojik ve epistemik uygunluk, bilmecenin cevabı ile öznesi arasındaki eşleşmelerle sağlanmaktadır. Diğer bir deyişle bilmecenin öznesi ile cevabı arasında imaj şemaya dayalı bir yapılandırma söz konusudur.

Published: June 2021

Due to Covid 19 today, most universities in Turkey have preferred online teaching methods for the courses in their programmes. Therefore, students’ readiness is important in the design and implementation of online learning. Also, their satisfaction with online courses is a necessary process for online learning applications to be successful. The aim of this study is to investigate the level of online readiness of students (1st, 2nd, and 3rd students) at Translation and Interpretation Department at Selçuk University. The data was gathered through the The Scale of Online Learning Readiness (Yurdugül and Alsancak Sırakaya, 2013) including five dimensions (18 items with a 5 point Lickert scale) as computer/Internet self-efficacy, self-directed learning, and motivation for learning, learner control, and online communication self-efficacy. The reliability coefficient of the scale was found to be Cronbach's Alpha coefficient (α = .864). The study shows that students at all class levels are familiar with the teaching in an online environment and do not have any difficulties. Also, it was found that male students had higher Online Communication Self-Efficacy levels than female students. It was determined that those aged 24 and above were more successful in managing their own learning than those in the 18-20 age groups. There was a significant difference was found between Computer and Internet Self-Efficacy sub-factor and owning a computer and it was found that those who participated in web-based training were higher in both the total and the Computer and Internet Self-Efficacy sub-factor compared to those who did not.
