Published: March 2022

Linear Feedback Shift Register (LFSR) systems are used widely in stream cipher systems field. Golomb used the recurrence relation to find the next state values of single LFSR depending on initial values, s.t. he can be considered the first who can construct a linear equations system of a single LFSR. Attacking of key generator means attempt to find the initial values of the combined LFSR's.In this paper, a Golomb's method introduced to construct a linear equations system of a single LFSR. This method developed to construct a linear equations system of key generator (a LFSR system) where the effect of combining function of LFSR is obvious. Finally, before solving the linear equations system, the uniqueness of the solution must be tested, then solving the linear equations system using one of the classical methods like Gauss Elimination. Find the solution of linear equations system means find the initial values of the generator. One of the known generators; Modified Bruer generator, treated as a practical example of this work.

Salivary Alpha-Amylase and Calcium levels Evaluation as a Biomarker in Stress Patients Undergoing Surgical Wisdom Tooth Extraction
Authors: Al_Sheakh Ali
Published: March 2022

The salivary enzyme alpha-amylase has been proposed as a biomarker for stress-induced activity of the sympathetic nervous system. In the growing field of amylase research, recent studies have underscored the usefulness of salivary alpha-amylase in this regard. Calcium is the major component of bones and teeth, and it is not surprising that disturbances in calcium metabolism have been implicated in most of the major chronic diseases, including renal disease, osteoporosis; and periodontal tissues.Twenty healthy Iraqi male undergo wisdom tooth extraction from undergraduates dental students were considered in this study with age mean of 22 years old, 2 ml samples of stimulated saliva were collected prior ten mints of surgical wisdom tooth removal, and recollected after one week fromsurgery from these students, the samples were analyzed to assess changes in ∝-amylase and calcium ion concentration under controlled conditions. The collected data predicted elevation of amylase level from ((7652.965 ±34.0410) to (7674.710 ± 68.8958) IU/L) with a significant change. And also increase in the calcium ion concentration level from (0.1465 ± 0.048) to reach level (0.1975± 0.100) mmol/L. Positive correlation were recorded between alpha amylase and calcium concentration when plotted the correlations values of stress and no stress individual's. In a conclusion. Acute stresscaused by wisdom tooth removal will elevate level of amylase in saliva significantly, howeverSignificant increasing in calcium concentration was observed in the stimulated saliva in comparison with the non-stimulated saliva with significant mean changes. However, our result predicted elevated levels of calcium concentration of the stimulated saliva than the non-stimulated (after extraction).

Cross-Validation of Elevation Data Interpolation
Authors: Ali Hussain
Published: March 2022

Most geographical spatial analysis requires a continuous data set and this study is designed to create such a surface. Digital model of landscape is an important part within creation of geo-information systems. It is an important tool in applications, which model an Earth’s surface like geomorphology, hydrology, geology, cartography, ecology, etc. Many software products offer different interpolation methods for creation of digital model of landscape. Its accuracy and quality is impacted by selection of an interpolation method and precision input data. Several studies have demonstrated that various spatial interpolation techniques perform differently depending on the type of attribute, geometrical configuration of the samples, spatial resolution, world region, etc. Hence, selecting the best interpolation technique for each particular situation is a key factor. The major objective of this paper is to assess the spatial variability of elevation data in Iraq by comparing different interpolation procedures. The elevation data were interpolated using a deterministic method (Inverse square distance) and geostatistical methods in ArcGIS. Cross-validation is a sample reuse algorithm for quantitative comparison of experimental performance of alternative interpolation methods. Cross validation can help make an informed decision as to which method provides the best results. Two diagnostic statistics are mainly considered in this paper from the results mean error, and root mean square error.

Sliding Mode PWM-Direct Torque Controlled Induction Motor Drive with Kalman Filtration of Estimated Load
Authors: Vo Hau Huu , Tran Dat Vinh Phat , Thieu Tri Quang , Le Tuan Anh , Dong Chau Si Thien , Brandstetter Pavel
Published: March 2022

The paper presents an application of sliding mode controller and Kalman Filter (KFSMC) in speed control of pulse-width-modulation direct torque controlled induction motor drive. The performance of the direct torque control (DTC) is degraded by the uncertainty of stator resistance. In order to increase the robustness of the controlled system to the uncertainty, a sliding mode controller (SMC) is utilized to replace the proportional-integral (PI) speed controller in the conventional DTC drive structure. Computation of SMC requires estimation of load, and Kalman Filter is integrated to reduce noise in load estimation and chattering phenomenon in speed response. Simulations are carried out at different reference speeds in a wide range of noises of stator resistance. Indices including ITAE, settling time, overshoot, and undershoot are employed to compare the performance of drive structures. Results confirmed the desired characteristics of the proposed drive structure.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
Formação ao Longo da Vida (FLV) de professores de Língua Portuguesa: agenciamentos e possibilidades
Authors: Oliveira Mateus Esteves de , Parreiras Vicente Aguimar
Published: March 2022

Neste artigo, discutimos, como objeto de pesquisa, o papel da Formação ao Longo da Vida (FLV) na trajetória profissional de um grupo de professores de Língua Portuguesa de uma cidade do interior de Minas Gerais. A noção de FLV considera o sujeito trabalhador como protagonista da sua trajetória formativa (FERREIRA, 2012; MEIRIEU, 2005; MERLE, 2006). Nesse sentido, buscamos, nas narrativas de vida dos participantes, traços de identificação para com essa ideia, bem como os benefícios, advindos da formação contínua, nas suas práticas pedagógicas. Para tal tarefa, como metodologia, utilizamos a Análise de Conteúdo (BARDIN, 2016) e projetamos oito categorias de análise. Por fim, concluímos que, mesmo havendo condições que dificultam a FLV no contexto pesquisado, os participantes reconhecem a necessidade de se colocarem como agentes centrais dos seus próprios percursos pessoal e profissional no decorrer da vida, agenciando, desse modo, diversos meios (AHEARN, 2001) para autoconstrução da identidade profissional.
Economic Policy Think Tanks in Germany and the United States and their Strategies of Policy Advice
Authors: Rauscher Natalie , Thunert Martin
Published: March 2022

This paper approaches the question if and how think tanks still matter, i.e. if they can make a difference, by looking at the contribution of American and German think tanks with a thematic focus on economic and social policy (broadly defined) to policy-advice in general and at their role in emphasizing advice relevant to the world of work and to a workforce/employee perspective in particular. The epistemological interest focuses on think tanks’s understanding of policy-making and advisory activities - including questions about the perceived influence and success of their advisory activities, the target groups of their consulting activities and the demand think tanks see for distinctive forms of policy advice, and in the question which consulting channels and instruments are utilized and how effective they are. In its second part, the paper addresses the question, how think tanks can advance and support policy research and policy advice around issues of the world of work and the employee/worker persepective.
Die Idee des bedingungslosen Grundeinkommens in Nordamerika – Debatten und Pilotprojekte in den USA und Kanada
Authors: Thunert Martin , Rauscher Natalie
Published: March 2022

Im zweiten Jahrzehnt des 21. Jahrhunderts hat die Diskussion um die Idee eines bedingungslosen Grundeinkommens oder Universal Basic Income (UBI) in Nordamerika Fahrt aufgenommen. Dazu trug in den USA auch das Buch des ehemaligen Gewerkschaftsführers Andy Stern mit dem Titel Raising the Floor bei, das in Deutschland bisher eher unbekannt blieb und daher hier rezensiert wird. Im medialen Diskurs der USA findet das Thema Grundeinkommen während der vergangenen zehn Jahre ein zunehmendes Echo, in der linksliberalen Medienlandschaft allerdings mehr als in der konservativen. Das bedingungslose Grundeinkommen taucht medial zumeist im Kontext der Themen automation und Zukunft der Arbeit - insbesondere im Zusammenhang mit den Themen sharing oder gig economy auf. Ein vielbeachtetes Experiment zum bedingungslosen Grundeinkommen fand in den Jahren 2017 und 2018 in der kanadischen Provinz Ontario statt. Obwohl das Pilotprojekt aufgrund eines Regierungswechsels vorzeitig beendet wurde, offenbarte die wissenschaftlich-konsultative Begleitung des Pilotprojektes wichtige Evidenz-basierte Erkenntnisse u.a. zum Verhalten der Bezieher eines Grundeinkommens und kann so dazu beitragen, die Debatte um ein Grundeinkommen zu versachlichen und die Begleitforschung zu diesem Thema zu verbessern, nicht nur in Nordamerika.
First records of the invasive slug Arion lusitanicus auct. non Mabille (Gastropoda: Pulmonata: Arionidae) in Romania
Authors: Păpureanu Anna-Maria , Reise Heike , Varga András
Published: March 2022

The invasive pest slug Arion lusitanicus (also known as Arion vulgaris) has spread throughout much of Europe within the last 60 years, becoming one of the worst agricultural and horticultural pest species. It has now been detected in Romania for the first time. There are dense populations at two sites in Braşov County (2013) and another occurrence in Mureş County (2012). We review occurrences in neighbouring countries and discuss evidence that A. lusitanicus might have arrived in Romania earlier. Further research on the species’ spread in Romania and on its impact on the native fauna and flora is necessary.

Do Barroco a periferia: a complexidade da cultura do Século XVII e XVIII no campo curricular das artes visuais
Authors: Melo Lucas Almeida de , Silveira Marcelo da Rocha
Published: March 2022

O artigo apresenta reflexões entre o Barroco e a Cultura do Século XVII e XVIII e as complexidades de seu ensino nas Artes Visuais. A disciplina acaba sendo uma perfumaria no campo curricular educacional e até mesmo um privilégio dentre as escolas. O Barroco é um período complexo que envolve relações entre política, geografia, história entre muitos outros aspetos.  A importância política do papel do professor está em sintonia com o currículo sobre o Barroco nas escolas e em suas periferias? É possível ensinar sobre a arte e a cultura Barroca sem pensar em questões de cunho político? A busca errônea por uma arte apolítica, em sua grande maioria, vinda de pais de alunos ou da direção da escola, esconde um abismo cultural sobre o papel da arte diante a sociedade e, além disso, ignora o racismo epistemológico do currículo. Como ensinar um período tão complexo com tão poucos tempos de aula em artes? É necessário aproximar o Barroco e entender suas reverberações na cultura contemporânea.

Em suma, pretendemos ponderar sobre os caminhos da Arte Educação no ensino virtual, bem como de estratégias híbridas e a necessidade de pensar e planejar para democratizar essas práticas, de maneira urgente.
Inclusive Physical Activity to Promote the Participation of People with Disabilities: A Preliminary Study
Authors: Di Domenico Felice , D’isanto Tiziana , Altavilla Gaetano , D’Elia Francesca , Raiola Gaetano
Published: March 2022

Background: Physical activity brings improvements in the quality of life in all individuals, disabled and non-disabled. There is little evidence in the literature of inclusive physical activity in which disabled and non-disabled people participate at the same level.

Objectives: The study aimed to demonstrate the effectiveness of an inclusive training program, structured in such a way as to encourage physical activity for all participants with and without disabilities, in improving body composition, explosive strength, and endurance.

Methods: A sample of twenty-four subjects (mean age: 24.09±3.92 years), 12 disabled and 12 non-disabled, was selected. Quantitative input and output data were recruited at 16-week intervals using a battery of tests: anthropometric measurements, Vertec Squat Jump test, and Yoyo Endurance Test. During the 16 weeks, all participants followed an appropriately structured training program in four mesocycle without any differences. Input and output data were compared employing the t-test for dependent samples.

Results and conclusions: The results showed statistically meaningful improvements at an alpha level set at 0.05 for the three parameters tested. These results confirmed the effectiveness of the proposed inclusive training protocol on the improvement of the tested parameters in all participants. These strategies didn't jeopardise the achievement of the overall objectives set; on the contrary, improvements in BMI, explosive strength, and endurance strength of 4.8%, 4.3%, and 56.2% respectively were observed.
El teatro itinerante y su público: El espectador como protagonista de una teatralidad renovada en la España republicana (1931-1936)
Authors: Guégo Rivalan Inès
Published: March 2022

Drawing on a number of travelling theatre experiments in Republican Spain (1931-1936), the present article examines their contribution to the revival of Spanish drama by studying more specifically the response of active, expressive, empathetic audiences. Beyond the Latin rule of placere, movere et docere, the necessary conditions for dramatic instinct and emotion to appear were then challenged. Examining the interactions of the barracos’, the missionaries’ and the public’s views sheds light on the making of the modern actor and spectator in the late Silver Age.

Partiendo de algunas experiencias de teatros itinerantes en la España republicana (1931-1936) se procura evaluar sus aportaciones a la renovación teatral española, en particular, estudiando las reacciones de públicos expresivos, empáticos y activos. Más allá del principio latino placere, movere et docere, en la época se cuestionaron también las condiciones necesarias para que pudieran advenir el instinto teatral y la emoción. El estudio de la interacción entre las miradas cruzadas de los barracos, de los misioneros y del público permite revelar la construcción del actor y del espectador de teatro modernos al final de la Edad de Plata.

A tool to model Virus Particle Exposure in Residences (ViPER)
Authors: Zimmerman Stephen M , Polidoro Brian , Ng Lisa C , Dols W Stuart , Emmerich Steven
Published: March 2022

Virus Particle Exposure in Residences (ViPER) is a web-based, single zone indoor air quality and ventilation analysis tool developed by the National Institute of Standards and Technology (NIST) for evaluating an occupant's relative exposure to virus-laden particles exhaled by a temporary, contagious visitor inside a dwelling (i.e., subsequently referred to as the home). This tool is specifically designed for use in a residential environment. When an occupant (the home's resident) anticipates having a visitor (a potential, temporary and continuous source of virus-laden particles), this tool can be used to vary a set of input parameters and then compare the changes to either particle concentration or integrated exposure. Some such parameters include home size, visit duration, and portable air cleaner effectiveness, as well as mechanical ventilation rates and heating, ventilating and air-conditioning system operation strategies. This tool is based on a database of 1,296 CONTAM simulation results. CONTAM is a multizone indoor air quality and airflow analysis program developed by NIST. ViPER allows users to compare a base scenario meant to represent their home against multiple what-if scenarios meant to mitigate their exposure to virus-laden particles. ViPER is available, along with CONTAM and other NIST-developed software, on the NIST Multizone Modeling Website https://www.nist.gov/el/energy-and-environment-division-73200/nist-mult .
Labor productivity as a factor of sustainable development of agricultural enterprises
Authors: Kolesnikova Tatiana , Naumova Tatyana , Smolennikova Lyudmila
Published: March 2022

In modern conditions of industrial and economic activity, the problem of labor productivity research and identification of reserves for its growth is acute. Labor productivity analysis allows you to assess the degree of labor organization, detect problems and develop methods to eliminate them. The purpose of the work is to study the indicators of labor productivity assessment and develop measures to improve the labor efficiency of employees of an agricultural organization. Recently, for the successful conduct of the production and economic activities of the enterprise, the issue of the working time spent on performing a certain type of work and the possible loss of profit from its irrational use is acute. It is proposed to eliminate the identified problems by introducing into the production cycle an automatic solution unit of the RIA NWR for the preparation of ready-made working solutions of mineral fertilizers and plant protection products. The introduction of this mortar unit will reduce the costs of production processes that cause the loss of part of the profit due to the irrational use of working time. The practical significance of the study is due to the fact that theoretical and practical recommendations can be used by specialists of agricultural organizations in order to increase the efficiency of the use of labor resources.
Ordinary Gamers - The Vanishing Violence In War Games And Its Influence On Male Gamers
Authors: Gieselmann Hartmut
Published: March 2022

War games often try to simulate the characteristics of real weapons - their range, loading times and the bullets’ caliber in order to create an authentic image of war. What they do not show is its authentic violence. Usually we do not see blood pixels and splatter orgies as in dungeon games in which the player has to fight monsters and zombies with eg. magic swords. Instead pictures of a clean war are presented in which civilians hardly ever appear and every weapon hits the target remote-controlled. Because of the simulation’s naturalism gamers may believe that a genuine war looks like the one the screen - and, in fact, today’s soldiers are not faced with the ‘white in the eye of the enemy’ any longer what they do see are symbols on the radar or abstract objects on a computer screen.
Accordingly, the real war more and more looks like a computer game while the computer game increasingly looks like reality.
Among the currently most popular war game genres are World War 2 games. They met their renaissance with the 1998 release of Stephen Spielberg’s Hollywood movie “Saving Private Ryan”. The film starts with an impressive staging of the battle following the landing at Omaha Beach in 1944 and subsequently a number of WW2 games were published in which gamers could re-enact the battle over and over on the internet. The respective gamers are organised in so called clans which often refer to historical divisions of Allied forces or German troops. Some of them even play under the names of well-known SS divisions such as “Leibstandarte Adolf Hitler”.

Most of the other gamers in this community do not seem to object to SS-clans who argue that they were only re-enacting their idols’ campaigns and did not share their biologist and racist world view. Thus, they try to promote the image of the bravely fighting SS-soldier in disregard of the war crimes committed by the Waffen-SS. Such arguments resemble the patterns used in speeches of the German Neo-Nazi party NPD.
In my article, I will analyse popular war games and the way they try to advance the image of the brave soldier and a intriguing weapon technology while neglecting the effects of violence and atrocities and how these games do not appear in the daily discussion about violence and are mostly elided by the protection of minors.
Assembling a Mosaic of the Future: The Post-Nuclear World of Fallout 3
Authors: Pichlmair Martin
Published: March 2022

Fallout is a series of role-playing games set in a prolonged nuclear age that follows the fictional Great War of 2077. Its story follows an alternate history scenario that branches from our history at about 1950. During the years following the nuclear fallout, the earth changes its face. Species mutate, some animals become sentient, and many humans lose their mind. This review focusses on the historic context of the nuclear age and how it informed the world of Fallout.
Just Gaming: On Being Differently Literate
Authors: Kendall Alex , McDougall Julian
Published: March 2022

How do videogame players who are ‘by day’ engaged in formal media and literacy education understand the boundaries between playing, reading and writing in the sphere of ‘Media 2.0’ in relation to the kinds of reading practices they are obliged to be immersed in during formal learning? How might empirical witness to such cultural practices usefully inform current educational policy debates in the United Kingdom in relation to the current ‘Literacy’ and ‘Media Literacy’ agendas and their attendant discourses?   This paper presents emergent findings from a qualitative research study undertaken with a small group of 16-17 college students who are regular players of Grand Theft Auto IV. It attempts to explore the multiplicity of their ways of telling (about being, in the game) in relation to poststructuralist theories of difference and in particular Lyotard’s (1985) notion of ‘gaming’ – whereby the rules of literacy are always-already local, fluid, changing and contested. Drawing on approaches from critical discourse analysis the thoughts and reflections of the students in relation to what they think it means to read, and be a reader and to play and be a player are explored.   By giving voice to game players who are often spoken for, this paper offers findings that will be informative for colleagues with an interest in Media Literacy as social practice, as opposed to a set of competences. Thus we suggest that the use of poststructuralist critical theory (informed by Lyotard’s ‘Just Gaming’ intervention) for such discussion is neither abstract nor ‘only’ theoretical but, because the videogame as a media form resists ‘orthodox’ representational concepts, that such a theoretical context is an obligation, and of direct ‘practical’ value in the development of policy and practice around Media Literacy.
Repelling the Invasion of the “Other”: Post-Apocalyptic Alien Shooter Videogames Addressing Contemporary Cultural Attitudes
Authors: Lizardi Ryan
Published: March 2022

In the current videogame landscape, a great deal of first-person shooters are being made that depict a post-apocalyptic invasion by an “alien” force that must be repelled. Culture in a given context can become preoccupied with certain issues and themes because of the societal situation it is born from. This allegorical function serves to speak to historically grounded contemporary concerns. Many of today’s contemporary concerns are related in some ways to 9/11, and the scholarly works that address the influence this event has had on videogames seem to pay closer attention to games that deal with these issues on an explicit level. This analysis moves past the singular historical event of 9/11 to show how latent long term attitudes and beliefs can be addressed by cultural texts on a more allegorical level. Through looking at the FPS invasion videogame texts themselves, such as the Resistance and Killzone series, it becomes clear that what these games are speaking to is a latent fear and mistrust of those culturally different. Through a fair amount of “Othering,” a steadfast ethnocentric viewpoint, and a reliance on the theme of the justified war, these games speak to contemporary cultural attitudes that are intertwined with the reputation of the US overseas. Instead of addressing these concerns head on, these videogame cultural texts place them within thinly veiled allegories that make explicit the desire to repel the invasion of forces that threaten the Western world.
Screening Play: Rules, Wares, and Representations in “Realistic” Video Games
Authors: Reyes Ian , Adams Suellen
Published: March 2022

In highlighting the apparatus as the keystone for the magic circle of video gaming, we displace players—the subject of ludology—and “text”—the subject of narratology. This is not to deny the importance of players’ agency or the meanings of texts in video gaming; rather it is to reconsider these with regard to the screening of player from played inherent in the gaming apparatus. To better understand the situation of homo ludens in these more mediated play spaces, we turn to Jacques Lacan’s account of “split” subjectivity and retread it by explaining how it may well explain the operation of a magic circle spanning three dimensions of screen-play: rules (Symbolic dimension), representations (Imaginary dimension), and wares (Real dimension). In the end, we come around to the other space of Huizinga’s theory—the connections with the non-game world—to show that the value of video game play is also found beyond the apparatus, that the experience and enjoyment of video games are affected in part by social reality and, in turn, social reality is being affected by the experience and enjoyment of video games. Arriving at this point by first theorizing the video game apparatus, however, highlights matters of video game design more so than issues of audience or textual analysis. To illustrate this perspective, we conclude by defining three ways to analyze video games in terms of “realism,” proposing three types of video game realism: representational, simulative, and inverse.
Discourse Engines for Art Mods
Authors: Poremba Cindy
Published: March 2022

This paper presents a genealogy of "art mod" (artistic videogame modification) definitions and frameworks. Such frameworks serve, either intentionally or unintentionally, to establish modding within a tradition of analysis and critique: whether participatory design, alternative media, folk art, and/or fine art. By situating the definition and history of art mods within a particular discourse, researchers construct the ground from which to make arguments towards organizing the reception and critique of these works. Such arguments include whether mods in general (and art mods in particular) are inherently political or banal (even boring), whether these works speak back at all to games themselves (and whether they should), whether these works are powerful and disruptive; or compromised (by virtue of their parasitic position), and as a result marginal. A genealogy of art mod frameworks highlights the boundary politics of the critique of art mods, and the problem of presenting transparent interpretive lenses in an interdisciplinary field such as game studies.
