There is little empirical research concerning whether flipped learning can be a viable alternative to the traditional present-practice-produce class of EFL (English as a foreign language) oral/aural skills for adult learners. The present study addresses this gap by investigating the effects of flipped learning on adult learners’ improvement in EFL speaking. Twelve Korean native speakers participated in a language course comprised of 24 sessions for a three-month period (60-minute per session, 2 sessions per week); six of them were assigned to a control group where they received traditional offline lectures in the classroom while the other six participated in flipped learning. Learners with similar backgrounds and attitudinal profiles were chosen as a focus group and their achievements and classroom behaviors were compared. The results indicate that when compared in pairs of shared learner variables, students in the experimental group invariably outperformed their counterparts in the control group on both immediate and delayed post-tests. Students in the flipped classroom also demonstrated some characteristic behavioral features that were not observed in the control group, such as connecting prior and current discussions, formulating more elaborated and personalized questions, and exercising autonomy by proposing their own discussion topics.

Authors:   The Institute of Educational research Chonnam National University, Sung Yoonhee
Published: January 2020

Compared to the extensive amount of research on the harmful effects of gender role conflict on men and others over the past few decades, relatively little attention has been given to examining factors that affect the formation of gender role conflict. Thus, the purpose of the present study was to explore the effects of egalitarian family environment(father s engagement in domestic chores, mothers power in financial decision-making), father characteristics(emphasis on success, emotional disconnection, lack of interest, violence, and mentorship), and contact with females(whether one has female siblings, proportion of female friends during middleand high school). Participants were 171 undergraduate and graduate male students from a university in a southern provincial area in South Korea. Results indicated the control variables and independent variables accounted for 15% of the variance in male gender role conflict. and that fathers violence and lack of interest were significant predictors of male gender role conflict. Limitations and directions for future research were discussed.
A Key Institution for Writing the Economic and Political History of Ottoman Muslims in the Early Modern Period
Authors: Spyropoulos Y.
Published: January 2020

Abstract This articles main argument is that in the course of the eighteenth century, the Janissary corps evolved into a powerful platform for the exchange of people, goods, and ideas between different localities covering a vast geographical area. By elaborating on this idea this paper maintains that the Janissaries should be treated as a key institutionfor the examination of Muslim economic and political history in the Ottoman periphery.We claim thatthe studyof their networkshas the potential to drastically redefine our current perception of the sociopolitical and financial role of Muslims in the early modern Ottoman Empire.Such a research can help us create a more balanced and less Eurocentric picture of the trading operations of Muslims in the regionand better understandthe dissemination of ideas and political movements between a number of Muslim communities where the Janissaries had a strong presence.

Аннотация Главныи тезис статьи то, что на протяжении XVIII века, корпус янычар эволюционировал в мощную платформу перемещения людеи, товаров и идеи между различными регионами обширного географического пространства. Обосновывая эту идею, автор статьи подчеркивает, что янычары как институт являются своеобразным ключом к исследованию экономическои и политическои истории исламских общин на периферии Османскои империи. На взгляд автора, исследование этих сетеи взаимодеиствия позволяет радикально пересмотреть нынешнее восприятие социополитическои и финансовои роли мусульман в Османскои империи раннего Нового времени. Подобные исследования дают возможность выработать более сбалансированную и менее евроцентричную картину мусульманских торговых операции в регионе, и лучше понять распространение идеи и политических движении среди различных исламских общин в тех регионах, где присутствие янычар было значимым.

Thus the load carrying capacities will be increase with this air breathing engines. This work gives a report on the design, analysis of optimal 2D scramjet engine inlet operating at Mach 7 without use of movable geometry. A computational study for scramjet inlet with different ramp angles is carried out. Several cases are considered to compress the air by rounding leading edge without moving the whole cowl up and down, by fixing the cowl lip and assuming axisymmetric inlet with rounded edge. The numerical tests are conducted to obtain maximum total pressure recovery, drag force and outlet Mach number for given flight condition. Two dimensional effects are studied with Navier-strokes approach to compute the pressure and Mach number at a different location. Oblique shock waves, expansion waves and shock wave interactions are primarily focused. Computational Fluid Dynamics (CFD) solver is used; steady flow simulations are carried out for inlet geometries with one, two, three and four ramps. Geometrical shape is redesigned based on oblique shock wave analysis. The corrected model is tested on Fluent with boundary layer considerations that the theoretical analysis is not able to cover. Lastly, a conclusion summarizing the design process is drawn and the optimal model is recommended for the Mach 7 inlet with different ramps with contraction ratio 10. It had been observed that two ramp scramjet inlet model has been preferred to use which has optimum pressure recovery and lower drag.

Polar codes, presented by Arikan, accomplish the ability to acquire nearly error-less communication for any given noisy channel of symmetry with "low encoding and decoding complexities" on a huge set of fundamental channels. As of late, polar code turned into the best ideal error-correcting code from the perspective of information theory because of its quality of channel achieving capacity. Though the successive cancellation decoder with approximate computing is efficient, the proposed ML-based decoder is more efficient than the former. As it is equipped with the Modified Processing Element which shows the better performance with the properties of Median Filter. The proposed ML-based decoder diminishes the area and power consumed and logic utilization. In the present paper, effective polar decoder architecture is structured and executed on FPGA utilizing Vertex 5. Here we examine the proposed unique construction that is appropriate for decoding lengthy polar codes with less equipment multifaceted nature.

A bus lane is a lane which is provide only for operating buses and used to avoid traffic congestion. The current bus transit system in Chennai, known as MTC (METROPOLITAN TRANSPORT CORPORATION), is accommodating about 4 million transport units sufficient to accompany increasing number of passengers. Buses have to share the lane with other vehicles, which affects their capacity, speed, reliability, and quality of service. Due to traffic congestions, travel during peak hours in Metropolitan cities has become unattractive. An attempt has been made in this paper to provide lanes only for operation of buses. Three arterial roads connecting Kelambakkam to Sholinganallur, Chennai central to TambaramVandaloor zoo to Tambaram were selected for the study. Traffic volume survey was conducted in these areas. Based upon the survey conducted and analysis made, suggestions are proposed for the exclusive bus lanes for theselected area where traffic congestion is more during peak hours.

In the North-East and Arctic regions of the Russian Federation, self-propelled drilling rigs of various modifications are in high demand for drilling of various purpose wells during exploration and engineering works. Due to the geographical inaccessibility of the production sites during the warm season, the bulk of drilling work is carried out in winter. The drilling fleet of exploration companies is becoming obsolete due to the lack of stable production of new generation drilling equipment by domestic plants, so now the process of purchasing imported equipment with higher technological capabilities, but not enough adapted to work in the harsh climatic conditions of the cryolithic zones of the northern and arctic regions, has begun. Besides, the enthusiasm for imported equipment, as we know, leads to constant dependence on foreign companies - suppliers of spare parts, technological means and materials and providing maintenance of drilling rigs.

Good’s and personal transport are becoming vital with time and money aspects and the roads and vehicles on the roads are expected to perform optimally drastically increasing the speed on the road network and constantly increasing and modifying the infrastructure needed to meet the demands. As the speed of the vehicle increases the accident rate and the damage caused by the collision will also increase. Safety of the road network is not to be compromised and proper systems to ensure the safe passage of the vehicle and proper warning systems are to be implemented. This system should be viable in all the condition and should be cost-effective. In this paper we are implementing a vision based system to identify the lane and other vehicles from the video it captures from a properly calibrated camera mounted on the front side of the vehicle. The system is designed to automatically and continuously detect the lines exploiting the new processing techniques and warning the driver if any other is in the breaking distance of the vehicle or if the vehicle is moving out of the lane. Cost effectiveness of the system is a major aspect as many of the available systems use equipment which very good at performing their task but are not affordable. Effort is put in making the system cost effective and not compromising with the reaction time and accuracy..

Published: January 2020

Проаналізовано, що типологізація культури є розгляд культури та її специфічні культурологічні підходи відповідно до її внутрішньої динаміки та історичного розвитку, класифікаційні особливості, розподілу за типами культур людської цивілізації. Простежено, що процедура типологізації культур залежить від обраного критерію, тому теорія культури може запропонувати різноманітні варіанти класифікацій. Виділено такі типи культур: етнічна культура, з розглядом дефініції «етнічність».  Показано, що етнічна культура найбільше виявляється у таких сферах, як природна, або національна, мова, а також в певному порядку побуту, у повсякденній поведінці, в традиціях, звичаях, віруваннях, типових ментально-психологічних рисах її носіїв. Зроблено висновок, що вищою формою етнічності в сучасному світі є нація і що на фундаменті етнічної спільності часто виникають національні культури. Доведено, що національна культура вміщує всю сукупність цінностей, норм, звичаїв, вірувань людей, що належать до однієї нації, тобто тих, хто має територіальну, господарську, ментальну і мовленнєву спільність. Простежено, що концептуальним підходом у типологізації культури є загальновизнана основа для об’єднання культур у групи, якою слугує поняття «культурна епоха». Зіставлено формалізаційний і цивілізаційний підходи у типологізації культур. Доведено, що цивілізаційний підхід у типологізації культур розрізняє окремі цивілізації за такими характерологічними критеріями, як історичний період, географічний простір, провідна технологія виробництва, політичні відносини, специфіка духовного життя. Проаналізовано, що загальновизнаною в теорії культури є історична типологізація культур,  концептуальним підходом якої є класифікація за історичним типом із подальшими узагальненнями, виокремленнями типових груп і тенденцій розвитку.

Spory na temat istnienia/wykorzystywania biografii na gruncie pedagogiki i nauk o wychowaniu uwidaczniają, jak wielopłaszczyznowe jest podejście pedagogów do badań biograficznych. Różnorodność tematów i ich ujęć, które ukazali autorzy artykułów zebranych w drugim tomie „Biografistyki Pedagogicznej”, tylko sygnalizują wielość problemów badawczych koncentrujących się wokół badania biografii, uczenia się z niej i wychowania poprzez poznawanie losów zarówno tych, którzy żyli w poprzednich wiekach, jak i osób z naszego otoczenia i nas samych. Bogactwo zarówno podejść badawczych, jak i możliwości praktycznego wykorzystywania biografii w szeroko pojętej pedagogii sprawiło, że redaktorzy zdecydowali się na ułożenie artykułów w tomie w porządku chronologiczno-problemowym. Układ taki daje możliwość przedstawienia ciągłości pewnych podejść badawczych i wychowawczo-dydaktycznych wykorzystujących biografię, a jednocześnie ukazujących ich ewolucję.
Ultra low loss and dispersion flattened microstructure fiber for terahertz applications
Authors: Habib Ahasan
Published: January 2020

In this paper, a rectangular core hexagonal lattice porous core photonic crystal fiber (PC-PCF) is reported for effectively guiding the terahertz light signal. Finite element method with circular perfectly matched layer boundary condition is employed to find out the propagation characteristics of this proposed porous core fiber. Extensive simulation results of that microstructure fiber over wide frequency range shows that very low effective material loss of 0.035 cm-1, large effective area of 1.79×10-7 m2 and high core power fraction of 36% can be obtained simultaneously. In addition, for same designing condition nearly zero flattened dispersion of 0.46 ± 0.07 ps/THz/cm can be achieved over 600 GHz frequency band in terahertz range. Furthermore, other important parameters like single mode operation, confinement loss and bending loss are also investigated rigorously for the proposed fiber. The excellent results of this optical waveguide will pave the way to implement it in various real life terahertz applications.
Tracing Media Audience Relationship Through Agenda Setting A Study of Cable News Channels in Pakistan
Authors: Raza Dr. Muhammad Riaz
Published: January 2020

The aim of this research study was to trace the relationship between media presentations and public priorities. To trace the media and public relationship for media influence on the public through agenda-setting, four issues Pak-US relations, energy crises, and national reconciliation ordinance were studied on two leading news cable channels, The Express and The Geo News Randomly selected news shows and bulletins for a period of one year have been examined to gauge the media agenda while a survey to cable television viewers of two news channels has been conducted separately to check the audience’s agenda on these issues. 156 news bulletins and the same number of prime time talk shows were analyzed through agenda-setting and framing models to gauge media agenda. Results confirmed strong connections between media’s issues salience and the audience’s issue priorities on four understudied issues. Correlations were measured from r +0.66 to r +0.90 with a p-value of less than .001. H1 and H2 have confirmed the strong media influence on the public priorities in ranking the understudied issues.
Unification of the Quintuple and Septuple Product Identities
Authors: Chu Wenchang , Yan Qinglun
Published: January 2020

By combining the functional equation method with Jacobi's triple product identity, we establish a general equation with five free parameters on the modified Jacobi theta function, which can be considered as the common generalization of the quintuple, sextuple and septuple product identities. Several known theta function formulae and new identities are consequently proved.

We show how to construct a cubic partial cube from any simplicial arrangement of lines or pseudolines in the projective plane. As a consequence, we find nine new infinite families of cubic partial cubes as well as many sporadic examples.
Double Crystals of Binary and Integral Matrices
Authors: Van Leeuwen Marc A. A.
Published: January 2020

We introduce a set of operations that we call crystal operations on matrices with entries either in $\{0,1\}$ or in $\mathbf N$. There are horizontal and vertical forms of these operations, which commute with each other, and they give rise to two different structures of a crystal graph of type $A$ on these sets of matrices. They provide a new perspective on many aspects of the RSK correspondence and its dual, and related constructions. Under a straightforward encoding of semistandard tableaux by matrices, the operations in one direction correspond to crystal operations applied to tableaux, while the operations in the other direction correspond to individual moves occurring during a jeu de taquin slide. For the (dual) RSK correspondence, or its variant the Burge correspondence, a matrix $M$ can be transformed by horizontal respectively vertical crystal operations into each of the matrices encoding the tableaux of the pair associated to $M$, and the inverse of this decomposition can be computed using crystal operations too. This decomposition can also be interpreted as computing Robinson's correspondence, as well as the Robinson-Schensted correspondence for pictures. Crystal operations shed new light on the method of growth diagrams for describing the RSK and related correspondences: organising the crystal operations in a particular way to determine the decomposition of matrices, one finds growth diagrams as a method of computation, and their local rules can be deduced from the definition of crystal operations. The Schützenberger involution and its relation to the other correspondences arise naturally in this context. Finally we define a version of Greene's poset invariant for both of the types of matrices considered, and show directly that crystal operations leave it unchanged, so that for such questions in the setting of matrices they can take play the role that elementary Knuth transformations play for words.
Maximal Fillings of Moon Polyominoes, Simplicial Complexes, and Schubert Polynomials
Authors: Serrano Luis , Stump Christian
Published: January 2020

We exhibit a canonical connection between maximal $(0,1)$-fillings of a moon polyomino avoiding north-east chains of a given length and reduced pipe dreams of a certain permutation. Following this approach we  show that the simplicial complex of such maximal fillings is a vertex-decomposable, and thus shellable, sphere. In particular, this implies a positivity result for Schubert polynomials. Moreover, for Ferrers shapes we construct a bijection to maximal fillings avoiding south-east chains of the same length which specializes to a bijection between $k$-triangulations of the $n$-gon and $k$-fans of Dyck paths of length $2(n-2k)$. Using this, we translate a conjectured cyclic sieving phenomenon for $k$-triangulations with rotation to the language of $k$-flagged tableaux with promotion.
On Two Problems Regarding the Hamiltonian Cycle Game
Authors: Hefetz Dan , Stich Sebastian
Published: January 2020

We consider the fair Hamiltonian cycle Maker-Breaker game, played on the edge set of the complete graph $K_n$ on $n$ vertices. It is known that Maker wins this game if $n$ is sufficiently large. We are interested in the minimum number of moves needed for Maker in order to win the Hamiltonian cycle game, and in the smallest $n$ for which Maker has a winning strategy for this game. We prove the following results: (1) If $n$ is sufficiently large, then Maker can win the Hamiltonian cycle game within $n+1$ moves. This bound is best possible and it settles a question of Hefetz, Krivelevich, Stojaković and Szabó; (2) If $n \geq 29$, then Maker can win the Hamiltonian cycle game. This improves the previously best bound of $600$ due to Papaioannou.
The prime power conjecture is true for $n < 2{,}000{,}000$
Authors: Gordon Daniel M.
Published: January 2020

The Prime Power Conjecture (PPC) states that abelian planar difference sets of order $n$ exist only for $n$ a prime power. Evans and Mann verified this for cyclic difference sets for $n \leq 1600$. In this paper we verify the PPC for $n \leq 2{,}000{,}000$, using many necessary conditions on the group of multipliers.
The Sandwich Theorem
Authors: Knuth Donald E.
Published: January 2020

This report contains expository notes about a function $\theta(G)$ that is popularly known as the Lovász number of a graph $G$. There are many ways to define $\theta(G)$, and the surprising variety of different characterizations indicates in itself that $\theta(G)$ should be interesting. But the most interesting property of $\theta(G)$ is probably the fact that it can be computed efficiently, although it lies "sandwiched" between other classic graph numbers whose computation is NP-hard. I have tried to make these notes self-contained so that they might serve as an elementary introduction to the growing literature on Lovász's fascinating function.
Ordres Bipartitionnaires et Statistiques sur les Mots
Authors: Han Guo-Niu
Published: January 2020

Soit $U$ un ensemble de couples de lettres. Foata et Zeilberger ont introduit les $U$-statistiques pour les mots quelconques. Dans cette note, on établit une condition nécessaire et suffisante pour que les deux définitions "maj$_U$" et "maj2$_U$", qu'on rencontre dans le cas classique, sont équivalentes. Il est remarquable que cette condition est exactement la même que celle qui a été trouvée pour l'équidistribution des deux statistiques "maj$_U$" et "inv$_U$".
The Robinson-Schensted and Schützenberger Algorithms, an Elementary Approach
Authors: Van Leeuwen Marc
Published: January 2020

We discuss the Robinson-Schensted and Schützenberger algorithms, and the fundamental identities they satisfy, systematically interpreting Young tableaux as chains in the Young lattice. We also derive a Robinson-Schensted algorithm for the hyperoctahedral groups. Finally we show how the mentioned identities imply some fundamental properties of Schützenberger's glissements.
