DETERMINATION OF OPTIMAL DESIGN AND WORKING PARAMETERS OF A VIBRO-PRESS FOR DEHYDRATION OF DAMP DISPERSIVE WASTES OF FOOD INDUSTRY
Authors: Sevostianov Ivan
Published: September 2022

Vibro-pressing equipment its one from most effective kinds of machines for dehydration of damp dispersive wastes of food industry (alcoholic bard, beer pellets, beet press, coffee and barley slime) for their further using as valuable additives to agricultural fodders or as fuel. In comparison with other equipment for mechanical dehydration (hydraulic, belt and screw presses, centrifuges) vibro-presses with hydraulic pulse, unbalanced or electromagnetic drive provide the same or higher productivity (20 ÷ 25 t / h) and energy efficiency (2,7 ÷ 3,2 kW / t) under lower final humidity of processed wastes (20 ÷ 25% against 70 – 76% - in case of realization of other mechanical methods). The last advantage allows do not conduct an additional drying of the wastes and that provides significant decrease of general power consuming of the working process. For provision of high efficiency parameters of the vibro-blowing dehydration there is need to provide optimal values of working and design parameters of the equipment for their realization. There are several approaches for research of the vibro-press equipment. The approaches that realized with help of differential equations of movement of the machine’s executive elements or differential equations of balances their energy provide high accuracy of calculations but because of complexity of these equations they are unsuitable for creation of a method of engineering design calculation of the machines. In the article are proposed algebraic equations and formulas for definition of optimal parameters of the vibro-pressing equipment for dehydration of damp dispersive wastes of food industry for realization of given parameters of efficiency and with consideration of initial and final physical-mechanical characteristics of the processed waste. There are conducted calculated diagrams of these parameters.
Ancestralidade e identidade em Negrum3 - Uma pedagogia negra acerca de gênero e de sexualidade
Authors: Azevedo de Mesquita Marcus Vinicius , Penha de Souza Edileuza
Published: September 2022

Black Brazilian Cinema is a concept that affirms the presence and the black culture in cinema since the arrival of the first literate slaves in Brazil, at the same time that it questions the structure of cultural and knowledge production. In this article, we seek a pedagogical approach to black cinema. The objective is to work with the universe of meanings and discourses existing in the film NEGRUM3 (2018), by the filmmaker Diego Paulino. We consider that ancestry, converted into an analytical category, is a key concept to understand the discourse present in the analyzed film, in which it becomes evident the need to establish a dialogue with the African past, in an attempt to resignify the boundaries of gender and sexuality for Afrodiasporic populations in the present and in the future. In this sense, we analyze the film considering the concept of Pretagogia that values the body and the orality, as a producer of black epistemology and identity. We establish dialogues with black authors/authors and carry out an analysis that considers the film as an artistic work that grounds meanings in narrative structures by means of filmic, visual and sound apparatuses. Our article demarcates the pedagogical character of Brazilian Black Cinema and demonstrates how it can make paradigmatic changes through the way it portrays certain themes, making possible the reconstitution of black history and the establishment of a pedagogy of hope.
Ficções do real no documentário Era o Hotel Cambridge - Eliana Caffé (2016)
Authors: Serafim Jose Francisco , Andrade Regina Gloria , Ramos Natalia
Published: September 2022

This communication aims to analyze the documentary made by Brazilian filmmaker Eliana Caffé, The Cambridge Squatter, made in 2016, from the point of view of reality and fiction, in view of the hybridization of genres proposed by the filmmaker. Caffé in his feature film mixes professional and social actors intertwining stories of migrants and refugees who find themselves living in what was once a luxury hotel in the downtown area of São Paulo, the Hotel Cambridge. For different reasons, they are in a situation of social vulnerability and in this collective space, they have one of the few possibilities of having a house, as well as food, in addition to being able to share stories and experiences ranging from refugees from the war in Congo to Syrians who left their country. The film also presents the situation of Brazilians, especially Northeasterners, who migrate from their places of origin in search of better living conditions, seeing this possibility in the city of São Paulo. In its political bias, it presents the various movements and NGOs involved in the struggle for the right to housing, and the problem of the abandonment of downtown and being occupied by “homeless” people. There are many themes punctuated in Caffé’s film, this communication will mainly address issues linked to this representation of poverty, the vulnerability of these people, and their struggle for a space of housing and social dignity, as well as the relationship and imbrication between the real and the fictional.
Online college writing education and self-directed learning
Authors:   Korean Association for Literacy, Lee Mijung
Published: September 2022

Due to the coronavirus pandemic (COVID-19), the university implemented nonface-to-face classes to prevent class loss and maintain stability despite quarantine. In a situation where online classes are becoming routine, it is important to study the efficacy of classes. Self-directed learning process is essential for writing efficacy. Self-directed learning refers to an active learning process in which students take the initiative to acquire knowledge. This study is important as a proactive learning process must be premised for online classes.
Writing classes involve a self-direction since it is required for the completion of a piece of writing. However, students feel the burden of communication, and the instructor feels the burden of a large number of people. This was found to be a phenomenon in which learning management was hindered and a sense of isolation deepened.
Self-directed learning activities in online classes were established as a process of mutual cooperation through step-by-step learning goals and group meetings. This, in turn, strengthened deep knowledge of specific subject areas and the knowledge of social context. The survey also showed similar results. Students showed a sense of achievement in the process of mutual cooperation and problem solving. Self-directed learning is not an outcome that must be accomplished alone. Self-directed learning becomes possible when combined with problem-solving team work based on respect.

Authors:   Korean Association for Literacy, Jeong Jongseong , Choi Jinoh
Published: September 2022

The purpose of this study was to investigate the perception of elementary school teachers about dyslexia, which was receiving major attention in school settings. Three hundred nine elementary school teachers were surveyed regarding their perceptions about the causes, symptoms, diagnosis, and treatment of dyslexia. Survey data were analyzed by descriptive statistics and regression analysis. The results of the analysis were as follows. First, it was found that elementary school teachers generally did not know or have inaccurate knowledge about dyslexia. In particular, the correct response rate for the treatment of dyslexia was 12.8%, and that for the cause of dyslexia was 24.3%, indicating that the level of accurate recognition was very low. Second, teaching experience, confidence of teaching, in-service training experience related to dyslexia, experience of completing subjects with dyslexia, and experiences of teaching students with dyslexia had a positive or negative effects on the perception of dyslexia. In particular, the rate of misconceptions among teachers who had in-service training experience and completion of subjects was relatively high. The results of this study indicate that teacher training or education for correct perceptions of dyslexia is urgent for elementary school teachers. Also, the results show that current dyslexia-related teacher training programs should be updated based on the latest research of dyslexia.
A Critical Discourse Analysis of Refugee Bill: Focusing on the comparison of bills proposed by the National Assembly before and after 2018
Authors:   Korean Association for Literacy, Lee Juhee
Published: September 2022

This study aims to critically analyze the discourse about refugees formed in Korean society and find the social wrong in the discourse through the Discourse Historical Approach, which combines historical and sociological approaches with linguistic analysis. To this end, taking 2018 into account, when 500 Yemeni refugees arrived in Korea, we compare and analyze the bills proposed before and after 2018 and find the discourse topic and strategy (description strategy, argumentation strategy, perspective strategy) for each period. This study shows that the refugee discourse before 2018 mainly deals with the ‘crisis of refugee protection’ from a humanitarian perspective, and refugee discourse after 2018 deals with the ‘crisis of the state’ from the perspective of xenophobia and neo-racism. These findings suggest that the discourse strategies used in refugee discourse after 2018 have the characteristics of propaganda in that they eventually stimulate public anxiety and create an atmosphere of fear, which implicate social wrong.

In addition, there are also research problems (research problems) about not achieving sales at Krisna souvenirs typical of Bali Sunset Road. This research was conducted on Krisna souvenirs typical of Bali Sunset Road with an unlimited population and the sample of this study amounted to 55 consumers. All data obtained from the questionnaire distribution are feasible to use, then analyzed using SPSS 24.0. The results of the study provide that relational marketing has a positive and significant effect on customer loyalty, e-word of mouth has a positive and significant effect on customer loyalty and relational marketing and e-word of mouth have a positive and significant effect on consumer loyalty. The implication of this research is that relational marketing can be improved by taking into account indicators of trust, reciprocity, bonding, and empathy. E-word of mouth can be improved by taking into account indicators of the willingness of consumers to talk about positive things about the company to others, recommending company services to others, and encouraging friends/relations to make purchases of company services. Consumer loyalty can be improved by taking into account indicators of regular repurchases, buying across product lines and services, recommending others, and pointing out immunity to competitors' attraction.

¿Existe sesgo político en el reparto municipal de los fondos regionales? El ejemplo de la Región de Murcia
Authors: Ríos Ana-María , García Antonio José , Guillamón María-Dolores , Benito Bernardino
Published: September 2022

Las debilidades que presenta el modelo de financiación local provocan que en algunos municipios haya surgido el debate sobre si la distribución de los fondos de los entes superiores de gobierno se realiza en base a principios adecuados o simplemente son resultado de criterios puramente partidistas. En este contexto, este trabajo tiene por objetivo analizar cuáles son los criterios que determinan la cantidad de fondos que reciben los 45 municipios que conforman la Región de Murcia por parte de ésta durante el periodo 2009-2017. A través de un modelo de datos de panel estimado por efectos fijos, se obtiene que el ciclo electoral es el único factor político relevante. Por su parte, los criterios presupuestarios de suficiencia, inversión y deuda per cápita son los más relevantes para determinar las transferencias que reciben los ayuntamientos. Finalmente, destacar que el desempleo ha sido el único factor socio-económico relevante.
Accelerating Early Massive Galaxy Formation with Primordial Black Holes
Authors: Liu Boyuan , Bromm Volker
Published: September 2022

Recent observations with JWST have identified several bright galaxy candidates at z ≳ 10, some of which appear unusually massive (up to ∼1011
M
⊙). Such early formation of massive galaxies is difficult to reconcile with standard ΛCDM predictions, demanding a very high star formation efficiency (SFE), possibly even in excess of the cosmic baryon mass budget in collapsed structures. With an idealized analysis based on linear perturbation theory and the Press–Schechter formalism, we show that the observed massive galaxy candidates can be explained with lower SFE than required in ΛCDM if structure formation is accelerated/seeded by massive (≳109
M
⊙) primordial black holes (PBHs) that make a up a small fraction (∼10−6–10−3) of dark matter, considering existing empirical constraints on PBH parameters. We also discuss the potential observational signatures of PBH cosmologies in the JWST era. More work needs to be done to fully evaluate the viability of such PBH models to explain observations of the high-z Universe.

Published: September 2022

There is an increasing interest and growing practice in Citizen Science (CS) that goes along with the usage of websites for communication as well as for capturing and processing data and materials. From an educational perspective, it is expected that by integrating information about CS in a formal educational setting, it will inspire teachers to create learning activities. This is an interesting case for using bots to automate the process of data extraction from online CS platforms to better understand its use in educational contexts. Although this information is publicly available, it has to follow GDPR rules. This paper aims to explain (1) how CS communicates and is promoted on websites, (2) how web scraping methods and anonymization techniques have been designed, developed and applied to collect information from online sources and (3) how these data could be used for educational purposes. After the analysis of 72 websites, some of the results obtained show that only 24.8% includes detailed information about the CS project and 48.61% includes information about educational purposes or materials.

Reflections on the ethics, potential, and challenges of artificial intelligence in the framework of quality education (SDG4)
Authors: Flores-Vivar Jesús-Miguel , García-Peñalvo Francisco-José
Published: September 2022

This article analyses and reflects on the ethical aspects of using artificial intelligence (AI) systems in educational contexts. On the one hand, the impact of AI in the field of education is addressed from the perspective of the Sustainable Development Goals (specifically, SDG4) of the UNESCO 2030 Agenda, describing the opportunities for its use by teachers and students. On the other hand, there is an emphasis on the uncertainties caused by the fears of some who think, for example, that AI robots will replace human teachers. The methodology used is based on a documentary review, supported by reports and studies conducted by researchers as well as institutions and organizations committed to the development of AI and its capacity for action in the educational field, and the ethical questions that experts and organizations around the world are raising. The results seek to influence and deepen the ethical implications that AI can have in the educational field. Finally, some critical questions about the ethics and challenges of AI in education are proposed, concluding with the need to add proposals with new research and political actions which could lead to the creation of an ethical observatory of AI for education.

El artículo analiza y reflexiona sobre aspectos coyunturales de la ética en el uso de los sistemas de Inteligencia Artificial (IA) en contextos educativos. Se aborda, por un lado, el impacto de la IA en el campo de la Educación, desde la perspectiva de los Objetivos de Desarrollo Sostenible (concretamente, ODS4) de la Agenda 2030 de la UNESCO, describiendo las oportunidades en su uso por parte de docentes y estudiantes. Por otro, se hace hincapié en las incertidumbres, sobrevenidas por los temores de algunos que piensan, por ejemplo, que los robots de IA reemplazarán a los profesores humanos. La metodología utilizada se basa en la revisión documental que parte de informes y estudios de investigadores, así como de instituciones y organismos comprometidos con el desarrollo de la Inteligencia Artificial y de su capacidad de acción en el ámbito educativo, para, a partir de ahí, abordar las cuestiones éticas que se vienen planteando por parte de expertos y de organizaciones de todo el mundo. Los resultados obtenidos buscan incidir y profundizar en las implicaciones éticas que la Inteligencia Artificial puede tener en el ámbito educativo. Finalmente, se proponen algunas cuestiones clave de la ética y los retos de la IA en la educación concluyéndose en la necesidad de sumar propuestas con nuevas investigaciones y acciones políticas, retos que podrían materializarse con la creación de un observatorio ético de IA para la educación.
(Un)founded fear towards the algorithm: YouTube recommendations and polarisation
Authors: García-Marín Javier , Serrano-Contreras Ignacio-Jesús
Published: September 2022

Social media have established a new way of communicating and understanding social relationships. At the same time, there are downsides, especially, their use of algorithms that have been built and developed under their umbrella and their potential to alter public opinion. This paper tries to analyse the YouTube recommendation system from the perspectives of reverse engineering and semantic mining. The first result is that, contrary to expectations, the issues do not tend to be extreme from the point of view of polarisation in all cases. Next, and through the study of the selected themes, the results do not offer a clear answer to the proposed hypotheses, since, as has been shown in similar works, the factors that shape the recommendation system are very diverse. In fact, results show that polarising content does not behave in the same way for all the topics analysed, which may indicate the existence of moderators –or corporate actions– that alter the relationship between the variables. Another contribution is the confirmation that we are dealing with non-linear, but potentially systematic, processes. Nevertheless, the present work opens the door to further academic research on the topic to clarify the unknowns about the role of these algorithms in our societies.

Las redes sociales han instaurado una nueva forma de comunicarse y entender las relaciones sociales. A su vez, en lo que podría entenderse como un aspecto negativo, los algoritmos se han construido y desarrollado bajo el paraguas de un amplio abanico de conjeturas y diferentes posiciones al respecto de su capacidad para dirigir y orquestar la opinión pública. El presente trabajo aborda, desde los procesos de ingeniería inversa y de minado semántico, el análisis del sistema de recomendación de YouTube. De este modo, y, en primer lugar, reseñar un resultado clave, las temáticas analizadas de partida no tienden a extremarse. Seguidamente, y mediante el estudio de los temas seleccionados, los resultados no ofrecen una clara resolución de las hipótesis propuestas, ya que, como se ha mostrado en trabajos parecidos, los factores que dan forma al sistema de recomendación son variados y de muy diversa índole. De hecho, los resultados muestran cómo el contenido polarizante no es igual para todos los temas analizados, lo que puede indicar la existencia de moderadores –o acciones por parte de la compañía– que alteran la relación entre las variables. Con todo ello, trabajos como el presente abren la puerta a posteriores incursiones académicas en las que trazar sistematizaciones no lineales y con las que, tal vez, poder arrojar un sustento más neto y sustancial que permita despejar por completo parte de las dudas sobre el papel de los algoritmos y su papel en fenómenos sociales recientes.

A new family of hybrid three-term conjugate gradient method for unconstrained optimization with application to image restoration and portfolio selection
Authors: Malik Maulana , Sulaiman Ibrahim Mohammed , Abubakar Auwal Bala , Ardaneswari Gianinna , Sukono
Published: September 2022

The conjugate gradient (CG) method is an optimization method, which, in its application, has a fast convergence. Until now, many CG methods have been developed to improve computational performance and have been applied to real-world problems. In this paper, a new hybrid three-term CG method is proposed for solving unconstrained optimization problems. The search direction is a three-term hybrid form of the Hestenes-Stiefel (HS) and the Polak-Ribiére-Polyak (PRP) CG coefficients, and it satisfies the sufficient descent condition. In addition, the global convergence properties of the proposed method will also be proved under the weak Wolfe line search. By using several test functions, numerical results show that the proposed method is most efficient compared to some of the existing methods. In addition, the proposed method is used in practical application problems for image restoration and portfolio selection.
Enhanced Aquila optimizer algorithm for global optimization and constrained engineering problems

Published: September 2022

The Aquila optimizer (AO) is a recently developed swarm algorithm that simulates the hunting behavior of Aquila birds. In complex optimization problems, an AO may have slow convergence or fall in sub-optimal regions, especially in high complex ones. This paper tries to overcome these problems by using three different strategies: restart strategy, opposition-based learning and chaotic local search. The developed algorithm named as mAO was tested using 29 CEC 2017 functions and five different engineering constrained problems. The results prove the superiority and efficiency of mAO in solving many optimization issues.

Media coverage is an important tool in the fight against smoking. So, in this paper we will incorporate media coverage in a deterministic SIRS model for smoking. Those who have studied this deterministic model have shown that by setting the constants of this model, we can control the tobacco epidemic. But this model is not very realistic: it does not take into account the action of media coverage and some other random factors. Thus, we incorporate the media coverage into this model and obtain a deterministic model with media coverage. Also, to take into account some randomness in the contact between individuals or sudden events that could disrupt the action of media coverage, we introduce in our deterministic model with media coverage white noise and jumps. We first prove the boundness of the solutions and the stability of the smoking-free equilibrium state of the deterministic model with media coverage. We prove that the solution of the stochastic differential equation with jumps of the stochastic model is unique, positive and global. Under certain conditions, we show that this solution oscillates respectively around each equilibrium state of our deterministic model. This allows us to consider conditions that lead to converge towards an extinction or persistence of smoking. The paper is ended by numerical simulations that corroborate our theoretical results.
Semantic Continuity in a Cross-Linguistic Perspective: Evidence from Slavic Verbs of Pulling and Pushing
Authors: Sherstyuk Alina , Reznikova Tatiana
Published: September 2022

This article presents some results of cross-linguistic research on verbs of pushing and pulling in nine Slavic languages. These data call into question the traditional notion of the semantic field as a clear-cut class of lexical units. It is shown that, due to semantic adjacency, fields may overlap, so that in different languages the same event may be described by verbs that would be assigned to different semantic fields in the traditional approach. The violation of inter-field boundaries is evidenced by both synchronic and diachronic data.

Systematic review of urinary biomarkers of female bladder outlet obstruction (fBOO)
Authors: Bilé Silva Andreia , Dinis Paulo Jorge , Abranches Monteiro Luís
Published: September 2022

Objective: Diagnosis of bladder outlet obstruction (BOO) in females is often challenging, not only because of the overlap in storage and voiding symptoms in women with various etiologies of lower urinary tract (LUT) dysfunction but also due to the lack of standardized urodynamic criteria to define the condition. There is an unmet need of biologic markers to evaluate BOO in females as an adjunct to other clinical criteria. We sought to elucidate the role of urinary biomarkers in female BOO. Material and methods: We performed a systematic review of studies involving urinary biomarkers in female BOO. The search was performed in PubMed. A total of 58 papers were retrieved and 2 were included for final analysis.Results: Currently, there are no validated biologic markers for female BOO available. Having a biomarker that can be obtained through a urine sample will be an invaluable tool to evaluate and counsel patients with LUT symptoms and possible BOO. The use of NGF as an indicator of BOO in female patients seems to be promising: NGF levels are elevated in women with BOO when compared with normal controls. Conclusions: We found that NGF levels may be applied as a useful biomarker in the diagnosis and evaluation of female patients with BOO symptoms. It will not completely replace other clinical diagnostic tools such as formal urodynamic testing but play a role as a supplement to it. Nevertheless, further studies should be conducted to establish NGF levels as a female BOO biomarker and a routine testing modality.

This paper reviews about the current technologies like artificial intelligence in the healthcare for smart cities.
Enumeration of three-quadrant walks via invariants: some diagonally symmetric models
Authors: Bousquet-Mélou Mireille
Published: September 2022

In the past$20$years, the enumeration of plane lattice walks confined to a convex cone—normalized into the first quadrant—has received a lot of attention, stimulated the development of several original approaches, and led to a rich collection of results. Most of these results deal with the nature of the associated generating function: for whichmodelsis it algebraic, D-finite, D-algebraic? Bymodel, what we mean is a finite collection of allowed steps.

More recently, similar questions have been raised for nonconvex cones, typically the three-quadrant cone$\mathcal {C} = \{ (i,j) : i \geq 0 \text { or } j \geq 0 \}$. They turn out to be more difficult than their quadrant counterparts. In this paper, we investigate a collection of eight models in$\mathcal {C}$, which can be seen as the first level of difficulty beyond quadrant problems. This collection consists of diagonally symmetric models in$\{-1, 0,1\}^2\setminus \{(-1,1), (1,-1)\}$. Three of them are known not to be D-algebraic. We show that the remaining five can be solved in a uniform fashion using Tutte’s notion ofinvariants, which has already proved useful for some quadrant models. Three models are found to be algebraic, one is (only) D-finite, and the last one is (only) D-algebraic. We also solve in the same fashion the diagonal model$\{ \nearrow , \nwarrow , \swarrow , \searrow \}$, which is D-finite. The three algebraic models are those of the Kreweras trilogy,$\mathcal S=\{\nearrow , \leftarrow , \downarrow \}$,$\mathcal S^*=\{\rightarrow , \uparrow , \swarrow \}$, and$\mathcal S\cup \mathcal S^*$.

Our solutions take similar forms for all six models. Roughly speaking, the square of the generating function of three-quadrant walks with steps in$\mathcal S$is an explicit rational function in thequadrantgenerating function with steps in$\mathscr S:= \{(j-i,j): (i,j) \in \mathcal S\}$. We derive various exact or asymptotic corollaries, including an explicit algebraic description of a positive harmonic function in$\mathcal C$for the (reverses of the) five models that are at least D-finite.
Tightness of supercritical Liouville first passage percolation
Authors: Ding Jian , Gwynne Ewain
Published: September 2022

Liouville first passage percolation (LFPP)
with parameter

\xi >0

is the family of random distance functions

\{D_h^\epsilon\}_{\epsilon >0}

on the plane obtained by integrating

e^{\xi h_\epsilon}

along paths, where

h_\epsilon

for

\epsilon >0

is a smooth mollification of the planar Gaussian free field. Previous work by Ding–Dubédat–Dunlap–Falconet and Gwynne–Miller has shown that there is a critical value

\xi_{\mathrm{crit}} > 0

such that for

\xi < \xi_{\mathrm{crit}}

, LFPP converges under appropriate re-scaling to a random metric on the plane which induces the same topology as the Euclidean metric (the so-called

\gamma

-
Liouville quantum gravity metric
for

\gamma = \gamma(\xi)\in (0,2)

).

We show that for all

\xi > 0

, the LFPP metrics are tight with respect to the topology on lower semicontinuous functions. For

\xi > \xi_{\mathrm{crit}}

, every possible subsequential limit

D_h

is a metric on the plane which does
not
induce the Euclidean topology: rather, there is an uncountable, dense, Lebesgue measure-zero set of points

z\in\mathbb C

such that

D_h(z,w) = \infty

for every

w\in\mathbb C\setminus \{z\}

. We expect that these subsequential limiting metrics are related to Liouville quantum gravity with matter central charge in
