An ROI-based robust video steganography technique using SVD in wavelet domain
Authors: Pilania Urmila , Tanwar Rohit , Gupta Prinima
Published: February 2022

Steganography is a technique that embeds secret information in a suitable cover file such as text, image, audio, and video in such a manner that secret information remains invisible to the outside world. The study of the literature relevant to video steganography reveals that a tradeoff exists in attaining the acceptable values of various evaluation parameters such as a higher capacity usually results in lesser robustness or imperceptibility. In this article, we propose a technique that achieves high capacity along with required robustness. The embedding capacity is increased using singular value decomposition compression. To achieve the desired robustness, we constrain the embedding of the secret message in the region of interest in the cover video file. In this manner, we also succeed in maintaining the required imperceptibility. We prefer Haar-based lifting scheme in the wavelet domain for embedding the information because of its intrinsic benefits. We have implemented our suggested technique using MATLAB. The analysis of results on the prespecified parameters of the steganography justifies the effectiveness of the proposed technique.
Flipped or traditional online teaching? Two different strategies to handle teaching in nursing education during the COVID-19 pandemic
Authors: Holm Patrik , Beckman Linda
Published: February 2022

Objectives

The aim of this study was to investigate differences in academic achievement between two groups of students who were taught the same course online within the nursing program but through two different teaching strategies and to examine the students’ attitudes towards flipped classroom.

Methods

Online lectures using Zoom was given to teach a course regarding the immune system and another course was taught the same subject in flipped classroom approach using video lectures followed by seminars. Academic achievement were compared between the groups, and perspectives on flipped classroom were investigated using a questionnaire.

Results

The main findings were that participation in flipped classroom seminars had a positive effect on academic achievement (OR 2.3 (CI [1.001–5.1]), and that students preferred the flipped classroom approach over traditional lectures.

Conclusions

This study suggests that a student centered teaching strategy like flipped classroom is an effective way to increase the students’ engagement and academic achievements.
Stress-strain characteristics and service life of conventional and asphaltic underlayment track under heavy load Babaranjang trains traffic
Authors: Setiawan Dian M.
Published: February 2022

A more durable rail track structure is fundamental in the railway industry, allowing the government to operate the train with higher speed and axle load. That means more passengers and better quality of railroads travel, thereby reducing the maintenance costs and ensuring passengers’ comfort and safety. The effect of a sub-ballast and asphalt layer thickness and freight train traffic with low operational speed on mechanical behavior and design life of conventional track and asphaltic underlayment track, are presented in this paper. One of the significant findings to emerge from this study is that an AC layer with minimum thickness of 0.20 m is required in the asphalt underlayment track application for Indonesian railway infrastructure to facilitate Babaranjang freight trains with up to 50% more tonnage. The evidence from this study also suggests that the asphalt underlayment track with 0.20 m thick of AC layer that contains grade PG70-28 binder could be beneficial to be applied in Indonesian railway system so that the rail track could be constructed with less volume of works than the regular Indonesia's conventional track with 0.40 m of sub-ballast layer.
Kantian vs. Platonic: The Ambiguity of Schopenhauer’s Notion of Ideas Explained via Its Origins
Authors: Sattar Alexander
Published: February 2022

The ‘Platonic Ideas’ in Schopenhauer’s metaphysics are (merely) appearances. On the other hand, as the immediate objecthood of the will, they are the essences of species and the only object of true aesthetic cognition, which leads beyond mere appearance. To explain this apparent incongruence, I offer an analysis of Schopenhauer’s early metaphysics (1809–1814), and its transformation into the metaphysics of will, fleshing out the several and divergent concepts of (Platonic) ‘idea’. Specifically, first, as part of his religious and neo-Platonic early philosophy; second, in the context of his ‘true criticism’ in the spirit of Kantian transcendental philosophy; third, as identical to the thing in itself as part of the metaphysics of will, heavily influenced by Kant’s notion(s) of ideas from CR and CJ. Explaining Schopenhauer’s mature notion of Platonic Ideas genetically as a set of homonymic notions helps us better explain its divergent meanings in WWR.

Authors: Li Rui , Song Yueqiang
Published: February 2022

In the present work, we are concerned with the multiple solutions for quasilinear Choquard equation with critical nonlinearity inRN{{\mathbb{R}}}^{N}. We show multiplicity results for this problem, which are characterized, respectively, by the new version of symmetric mountain-pass theorem and the mountain-pass theorem for even functionals. The novelty of our work is the appearance of the convolution terms as well as critical nonlinearities.

Authors: He Qiming , Xiang Gaoqiang , He Chengen , Lai Qi , Yang Yingkui
Published: February 2022

The coupling of metal oxide nanoparticles and electrochemically active polymers has been considered as an effective way to improve the lithium storage performance of individual electrode materials. This work reports an electrospinning process followed by thermal annealing to produce composite nanofibers of cyclized-polyacrylonitrile (cPAN) containing Co3O4 nanoparticles (cPAN/Co3O4). The as-prepared cPAN/Co3O4 nanofiber exhibits a porous nanostructure with an average diameter of 85 nm. When used for lithium-ion battery, the cPAN/Co3O4 anode delivers a reversible specific capacity as high as 997.6 mA h g−1 at 0.1 A g−1, and still maintains 396.5 mA h g−1 at 1.0 A g−1. Meanwhile, the cPAN/Co3O4 anode shows good cycling stability with a retention of 81% capacity after running 50 cycles at 0.1 A g−1. The electrochemical performance of cPAN/Co3O4 significantly outperforms its individual counterparts of cPAN and Co3O4.
Attentional Structure and Phenomenal Unity
Authors: Wiese Wanja
Published: February 2022

Some authors argue that phenomenal unity can be grounded in the attentional structure of consciousness, which endows conscious states with at least a foreground and a background. Accordingly, the phenomenal character of part of a conscious state comprises a content aspect (e.g., hearing music) and a structural aspect (e.g., being in the background). This view presents the concern that such a structure does not bring about phenomenal unity, but phenomenal segregation, since the background is separated from the foreground. I argue that attention can still lead to a form of phenomenal unity that connects the foreground with the background. Experiencing oneself as controlling the focus of attention can, at least occasionally, bring about an experienced connection between the attentional foreground and the attentional background of a conscious experience.

Open-Span Printing Method for Assessment of Early-Age Deformations of Additively Manufactured Cement-Based Materials Using an Isosceles Triangle
Authors: Moini Reza , Olek Jan , Zavattieri Pablo D. , Youngblood Jeffrey P.
Published: February 2022

Successful additive manufacturing of cement-based elements depends upon understanding the materials' fresh properties and their influence on early-age deformations. However, to be able to monitor early-age deformations of cement-based materials for 3D-printing applications, one must be able to assess these distortions “in situ,” that is, during the actual 3D-printing operation. This paper discusses the use of a new open-span printing method as a tool for evaluating the deformation of freshly printed plain cement paste filaments containing chemical admixtures. The method uses a rigid isosceles triangle as a support structure that allows for the deposition of filaments over varied span lengths. The vertical deformations of filaments printed with materials of variable composition (i.e., different solids content and types of chemical admixtures) were quantified. Elements printed using materials with increased solids content were observed to develop reduced mid-span deflection across span lengths larger than 12 mm. This test method can be used to inform the selection of materials in order to achieve suitable shape stability (e.g., to ensure minimal early-age deformations).
A Methodology to Assess Early Age Fracture Performance of 3D Printable Cementitious Mixes
Authors: Kompella Sriram K. , Lo Monte Francesco , Cucchi Marco , Marcucci Andrea , Bassani Andrea , Guanziroli Stefano , Ferrara Liberato
Published: February 2022

Digital fabrication with cement-based materials requires that specific attention is paid to rheological and mechanical material properties in both the fresh and hardened states. For the layered extrusion process, the cement-based material needs to satisfy the “printability” requirement, which may involve fracture resistance at very early ages to multiaxial stress states. This paper presents a methodology to identify the mechanical response under direct tensile and shear stresses as a function of time to determine the printability of the mix, with reference not only to the quality of the finishing but also to the speed of the printing process.

La cornamenta del toro de lidia es la parte anatómica más delicada de este animal, dado que su carácter ofensivo y estresable hace que sufra lesiones traumáticas durante el año previo a la lidia. Actualmente, se protege el cuerno con una funda de fibra de vidrio, con el objetivo de proteger su integridad. Con este trabajo, se pretende estudiar la resistencia mecánica del cuerno del toro de lidia; se analiza la posible influencia del enfundado. Para ello, se ha recogido cuernos de 50 toros de lidia de 4 a 5 años; 25 de ellos habían sido enfundados 6 meses antes de su lidia. Se ha analizado la resistencia mecánica del cuerno: cepa, pala y pitón; se utiliza el equipamiento Instron Electropulse E10000, siguiendo una metodología similar a la empleada por Horcajada et al. (2009). Se realiza tres pruebas de resistencia mecánica: compresión directa, tracción indirecta y flexo-tracción. Todas reflejaron una alta resistencia del cuerno, sin diferencias entre sus partes. Se observa un efecto beneficioso del enfundado, favorece el espesor del estuche de queratina en la cepa del cuerno; el cual fue mayor en los cuernos de los animales enfundados. Además, se comprueba una mayor resistencia de los cuernos enfundados en la prueba de tracción indirecta. Por otra parte, los cuernos de mayor longitud y diámetro resistieron presiones más altas, absorbiendo el hueso cornal, mayoritariamente, la presión ejercida.

Invention of a computer "Kyiv" architecture using a concept of Addressed Programming Language
Authors:   National University ", Yuschenko Yu.O. ,   Kyiv-Mohyla Academy"
Published: February 2022

The article is devoted to the history of the origin of high-level programming in Ukraine. The transition from calculations by arithmometers and logarithmic rulers to solving problems on the computer "Kyiv" using pointers and tree-like formats (abstract data types are analogous) is described. The factors that contributed to this transition include: the experience of providing instructions for calculations by arithmometers, and the experience of programming on MESM. As a result a computer "Kyiv" has been developed with a hardware-implemented possibility of high-level programming, invention of the Addressed Programming Language with indirect addressing (pointers), tree formats and declarative capabilities. Hardware-realized demining of pointers in the computer "Kyiv" is one of the outstanding inventions of Ukrainian engineers and mathematicians at the initial stage of the information technologies development. At that time it was significantly ahead of the world technologies. Programming in computer "Kyiv", unlike Plankalkül, could identify and process complex structures. The paper describes the individual applications of the Address Programming Language, which was implemented on many Soviet-made computers and has been used by programmers for more than 20 years. Due to the so-called "Iron Curtain", scientists in the field of programming outside the post-socialist world still do not know about the invention of pointers by Kiev scientists. A textbook describing the Addressed Programming Language was translated into many languages. A monograph with a description of the computer architecture "Kyiv" and of the Addressed Programming Language was translated into English and published in the United States in 1966.

Introducción. El consumo de frutas y vegetales correlaciona inversamente con la incidencia de enfermedades degenerativas como diabetes, enfermedades cardiovasculares, ciertos tipos de cáncer y cataratas asociadas al envejecimiento, dada la acción de compuestos bioactivos como vitamina C, polifenoles y carotenoides. Objetivo. Evaluar el perfil nutricional de once frutas cultivadas en Costa Rica. Materiales y métodos. Este estudio se realizó en el Centro Nacional de Ciencia y Tecnología de Alimentos de la Universidad de Costa Rica, en el 2010. Se determinó el contenido de fibra dietética, polifenoles totales, reportados como equivalentes de ácido gálico (EAG), carotenoides totales expresados como µg β-caroteno y la capacidad hidrofílica de absorción de radicales de oxígeno (H-ORACFL) de once frutas tradicionales o subutilizadas: banano (Musa AAA subgrupo Cavendish cv. ‘Grand Naine’), mora tropical de altura (Rubus adenotrichos cv. ‘vino con espinas rojas’), melón (Cucumis melo cv. ‘Veracruz’), higo (Ficus carica cv. ‘Brown-Turkey’), mango (Mangifera indica cv. ‘Tommy Atkins’), papaya (Carica papaya híbrido ‘Pococí’), pejibaye (Bactris gasipaes H.B.K), piña (Ananas comosus cv. híbrido MD-2 ‘Gold’), membrillo (Cydonia oblonga), jocote (Spondias purpurea cv. Tronador) y tomate de árbol rojo (Solanum betaceum). Las frutas fueron recolectadas en localidades de San José, Cartago, Alajuela, Guanacaste y Limón. Resultados. Seis de las frutas estudiadas presentaron contenidos de fibra dietética entre 4,2 y 6,6 g 100 g-1. La mora tropical de altura presentó el mayor contenido de compuestos fenólicos totales (538 ± 97 mg EAG 100 g-1) y la mayor actividad antioxidante (62,1 ± 4,0 μmol equivalentes de Trolox g-1), y el pejibaye cocido presentó el mayor contenido de carotenoides (72 ± 4 µg β-caroteno g-¹). Conclusión. Se evidencia los altos contenidos de compuestos bioactivos en frutas comúnmente cultivadas en Costa Rica, características nutricionales asociadas a beneficios para la salud, respaldados por estudios clínicos y epidemiológicos.
La traduction chez Dezső Kosztolányi et Jorge Luis Borges: une pensée du décentrement
Authors: Caupenne Marie-Julie
Published: February 2022

What do Dezső Kosztolányi and Jorge Luis Borges have in a common ? There are both short stories’ writers and translators who wrote essays on the art of the translation. Moreover they tried to put the problems of translation into fictions. We propose first to study the different translation theories of these two authors. The second point concerns the analysis of two short stories: “Gallus” from Kosztolányi’s Kornél Esti cycle and “El enigma de Edward Fitzgerald” from Borges’ complete works because Gallus and Fitzgerald, the main characters, are translators; in fact, the thought of translation is not only present in the theory, but could be elaborated through fictional texts.

The present chapter focuses on discussing the idea of his personal socialist believes. The author discusses socialism by dividing it into two parts.

Next, the second (part on the) content of faith will also be further divided into two sections: (1) the revolution of thought, and (2) practical action.
Openness towards the Religious Other in Buddhism
Authors: Roloff Carola
Published: February 2022

This chapter argues that in Buddhism—irrespective of the religious other’s understanding of ultimate reality—there is potential for fruitful exchange and common ground with other religions. For the peaceful and respectful coexistence of religious communities it is crucial to address—and not to exclude or minimize—the different views of their respective religious truths. Cultivating an inner attitude of benevolence and openness will prove advantageous for our interaction with others. Three central Buddhist teachings are analyzed in view of their potential for openness towards the religious others in theory and in practice: the Four Immeasurables, the Skill in Liberative Technique and the Two Truths. These teachings, although not explicitly spoken about, still have the potential to generate openness towards and elaborate on the religious other with reference to modern societies in the 21st century.

Komersialisasi adalah sebuah proses dimana struktur dan isi sebuah media diatur dan disesuaikan dengan keinginan konsumen atau khalayak, sehingga konten dari media tersebut hanya berdasarkan profit oriented saja, yang mengakibatkan isi media menjadi seragam, stereotipikal, dangkal dan tidak otentik. Terdapat beberapa pandangan ketika kita menelaah media dengan perspektif ekonomi politik. Diantaranya perspektif liberal dan perspektif kritis

Algunas notas de lectura para Freud después de la Primera Guerra Mundial
Authors:   Universidad de Granada, Rodríguez Juan Carlos
Published: February 2022

Si hay un texto que me haya impresionado siempre en la historia de la literatura escrita en castellano es sin duda un poema sin nombre de autor, un poema anónimo (¿qué importa el nombre propio en este caso?). En el siglo XVI-XVII se podía escribir así: “No me mueve mi Dios para quererte / el cielo que me tienes prometido”. Esto ya de por sí es básico. Lo que mueve al amor es el amor del Cristo crucificado y bajado a la Tierra para salvarnos. El “homo viator”. Pero en verdad lo que impresiona no es eso. Lo que impresiona es exactamente la ausencia del daño, aunque se sea consciente del daño
Linguistic Progmatics of English Borrowings in Russian Mass Communication Discourse
Authors:   Volgograd State University, Volkova Olga
Published: February 2022

The paper focuses on linguistic and pragmatic peculiarities of English borrowings used in the discourse of mass communication in Russian. The analysis of Russian-language web content has enabled the author to identify the symbolic significance of shoe names borrowed from the English language. The system of values referred to a fashionable lifestyle was revealed and described; the thematic domains, such as sports, healthy lifestyle, active life position, and eco-activism are highlighted. The shoe names borrowed from English are regarded in the article in terms of translingual units and are defined as linguistic signs, which belong to another language, but the speakers, who are the agents of network communication, use them ad hoc to convey the ideas through switching the language code. Translingual units are found out to be universal symbols in the context of global mass culture. Having crossed the borders of the languages, they broadcast new values. Meanwhile, they spontaneously go through the main stages of linguistic adaptation and actively penetrate the network content of mass communication. The article presents the techniques of the borrowed shoe names translingual adaptation. The identified techniques include translingual derivation, partial grammatical categorization, conversion and blending, which consists in the occasional composition of the original, graphically unadapted English stem – a proper noun denoting a brand name of the shoe manufacturer, and a Russian suffixoid -ovsk-, which forms relative adjectives with the generalized meaning of sharing characteristics, prescribed to the object, indicated by the root morpheme. Phonetic assimilation of translingual shoe names presupposes following pronunciation rules of the Russian language, including the reduction of vowels in the first pre-stressed syllable; devoicing voiced consonants at the end of a word; palatalization; coexistence of diphthongized and monophthongized variants of vowel pronunciation, which indicates the incompleteness of phonetic adaptation.
