Authors: Weber Philip , Mahmood Faisal , Ahmadi Michael , von Jan Vanessa , Ludwig Thomas , Wieching Rainer 
Published: March 2023

AbstractIn recent years, emerging approaches to chatbot-guided food coaching and dietary management, while innovative and promising in nature, have often lacked long-term studies. Therefore, with this work, we pursued a participatory approach within a design case study to the co-design and development of a nutrition chatbot for elderly people. Overall, 15 participants were directly involved in the study, of which 12 participated in the initial co-design phase, seven in the first real-world evaluation study over four weeks, and three in the second evaluation study over seven weeks. We contribute to the fields of Human-Computer Interaction by showing how the long-term use of such a chatbot in the area of nutrition looks like, which design implications arise for the development of nutrition chatbots, and how a participatory design approach can be realized to design, evaluate and develop nutrition chatbots.

Authors: Al-Khafajy Dheia G. Salih , Majeed Mashhadi Radhwan R. 
Published: March 2023

Abstract
The purpose of this study is to investigate the effect of an elastic wall on the peristaltic flow of Carreau fluid between two concentric cylinders, where the inner tube is cylindrical with an inelastic wall and the outer wall is a regular elastic sine wave. For this problem, cylindrical coordinates were used, and a short wavelength “relative to channel width for its length,” as well as the governing equations of Carreau fluid in the Navier–Stokes equations. Then, the analytical solution has been investigated by using the regular perturbation technique. The solutions obtained by this perturbation are up to the fourth-order in dimensionless Weissenberg number (

W

e

{W}_{{\rm{e}}}

). The performed computations of various parameter values such as velocity, shear stress, and wave frame streamlines are discussed in detail for different values of the Weissenberg number (

W

e

{W}_{{\rm{e}}}

). The obtained results demonstrate that the fluid velocity increases with the increase in the value of

W

e

{W}_{{\rm{e}}}

and some features of the wall, while the opposite behavior is observed with the increase in other features of the wall. Hence, the presented numerical analysis reveals many aspects of the flow by considering a non-Newtonian Carreau fluid model, and the presented model can be equally applicable to other bio-mathematical studies. The results were evaluated using the Mathematica software program. The Mathematica program was used by entering various data for the parameters, where the program showed the graphs, then the effect of these parameters became clear and the results were mentioned in the conclusion.
A time-step-robust algorithm to compute particle trajectories in 3-D unstructured meshes for Lagrangian stochastic methods

Published: March 2023

Abstract
The purpose of this paper is to propose a time-step-robust cell-to-cell integration of particle trajectories in 3-D unstructured meshes in particle/mesh Lagrangian stochastic methods.
The main idea is to dynamically update the mean fields used in the time integration by splitting, for each particle, the time step into sub-steps such that each of these sub-steps corresponds to particle cell residence times.
This reduces the spatial discretization error.
Given the stochastic nature of the models, a key aspect is to derive estimations of the residence times that do not anticipate the future of the Wiener process.
To that effect, the new algorithm relies on a virtual particle, attached to each stochastic one, whose mean conditional behavior provides free-of-statistical-bias predictions of residence times.
After consistency checks, this new algorithm is validated on two representative test cases: particle dispersion in a statistically uniform flow and particle dynamics in a non-uniform flow.
A Warehouse Theory of Capital Accumulation
Authors: Cheung Steven N. S. 
Published: March 2023

Abstract
An interesting puzzle in 20th century economics is that in her magnum opus, The Accumulation of Capital (Robinson, J. 1956. The Accumulation of Capital. London: Macmillan.), Mrs. Joan Robinson made no mention of the name Irving Fisher. Zero, none. In my view, Mrs. Robinson was the greatest British economist since Alfred Marshall, and Irving Fisher was the greatest economist ever lived. Yes, with a great diversity of subject matters, Fisher in economics was a Mozart in music, a Rembrandt in art, or a Darwin in biology. In short, Fisher was a genius.
Integrated circuits based on broadband pixel-array metasurfaces for generating data-carrying optical and THz orbital angular momentum beams

Published: March 2023

Abstract
There is growing interest in using multiple multiplexed orthogonal orbital angular momentum (OAM) beams to increase the data capacity of communication systems in different frequency ranges. To help enable future deployment of OAM-based communications, an ecosystem of compact and cost-effective OAM generators and detectors is likely to play an important role. Desired features of such integrated circuits include generating and detecting multiple coaxial OAM beams, tunability of OAM orders, and operation over a wide bandwidth. In this article, we discuss the use of pixel-array–based metasurfaces as OAM transmitters and receivers for mode division multiplexing (MDM) communications in near-infrared (NIR) and terahertz (THz) regimes.
Production Network and Emission Control Targets-Theoretical Approach
Authors: Eslamipoor Reza , Wang Zheng , Kolade Oluwaseun 
Published: March 2023

Abstract
By spurring trade, the level of income and consumption and production increase, which consequently causes a more polluted environment. As global economic integration escalates, the possibility of contention becomes more translucent. The foundation of this article is based on the Ricardian model regarding consumption and production pollution function in six scenarios depending on Autarky or trade situation. There is also a difference in the relative labour size of countries. Also, pollution tightness can clarify whether there are any concerns about climate change regarding the production pollution function and consumption pollution function. The theoretical approach proves that unemployment does not occur when we have no concerns about climate change and this tightness of pollution would not impact the level of production and consumption. The emission intensity, relative labour size and tightness of pollution targets are the key elements discussed in both Autarky and trade. The critical point about trade is that it enters specialization, and the home country only produces good 1 and the foreign country only produces good 2. The main finding of this paper, based on a simple theoretical approach, is about the impact of one unit change in relative labour size regarding pollution tightness with respect to the labour force of both home and foreign countries is provided at the end.
SOCIAL AND PEDAGOGICAL SUPPORT FOR INTERNALLY DISPLACED CHILDREN UNDER MARTIAL LAW
Authors: Protas Oksana 
Published: March 2023

Millions of Ukrainian families with children have been forced to leave their permanent place of residence, moving to safer places under the current conditions of martial law in the country, which in its effects corresponds to the difficult life and often traumatic circumstances. The challenge arises in the need to meet the needs of new residents for social, medical, psychological, legal, social and pedagogical services, and appropriate living conditions. Forced moving can cause emotional and physical stress, fear, depression, inability to adequately assess events and make decisions, respond to them, and adapt to the changed conditions. The need for social protection and psychological and social and pedagogical assistance takes on increasing importance for families, in particular for children in difficult circumstances as a result of military actions. The article reveals the peculiarities of providing social and pedagogical support to children of internally displaced persons under martial law. The need for a multilevel comprehensive system of support for victims and displaced persons, the organization of intersectoral and interdepartmental interaction between specialists of corresponding services in providing complete psychological and social and pedagogical help, and coordination of efforts of various specialists is brought up to date. The need for social and pedagogical and psychological support for internally displaced children, which may require the recovery of their mental health and social well-being, an appropriate response to hostilities, and adaptation to new, changed conditions, is emphasized. It was established that social and pedagogical support is a type of activity of a social care teacher, aimed at organizing preventive and operational social and psychological and pedagogical assistance in preventing and overcoming situations that violate the vital activities of children. An analysis of models of social and pedagogical support for internally displaced children in difficult circumstances has been conducted. The technology of social and pedagogical support for children of internally displaced persons is considered. The relevant directions and content of social and pedagogical support for children of internally displaced persons under martial law are outlined. It is noted that modeling and organization of social and pedagogical support for children of internally displaced persons who suffered from military operations or were forced to leave their homes will help them to overcome the psychological trauma of military events, and will contribute to successful adaptation to the new changed conditions.
Keywords: internally displaced persons, difficult life circumstances, social services, adaptation of internally displaced children, social and pedagogical support, model of social and pedagogical support for children of internally displaced families.

Published: March 2023

The article reveals the theoretical aspects of learning English and its place and role in modern education. The main tasks and content of profilisation are determined. The methods of reading and listening to the texts while learning English and ways of improving them are studied. Nowadays, school profilisation is one of the important directions of Ukrainian general education modernisation. The introduction of subject-oriented instruction in the junior (1st-4th) grades of general educational institutions is determined by the current trends in the national education development, the state and society social services commissioning to school, the socio-economic and socio-cultural development of Ukraine, as well as by the analysis of the successful practices of foreign countries’ school education. The theoretical basis for the subject-oriented instruction implementation is the Laws of Ukraine “On Education” and “On General Secondary Education”, the Concept of Subject-Oriented Instruction in Junior School, the State Standard of Basic and Complete General Secondary Education and other regulatory documents. The main theoretical advances of domestic and foreign scientists with reference to the best practices in junior students’ education organisation are embodied in the Concept of Subject-Oriented Instruction in Primary School.
Keywords: profilisation, foreign language activity, authentic speech, monologue speech, foreign language communicative competence, reading and listening skills, literary and colloquial speech.

CULTURAL APPROACH IN SHAPING THE READINESS OF FUTURE EDUCATORS FOR CREATIVE ARTISTIC AND CONSTRUCTIVE ACTIVITY WITH PRESCHOOLERS
Authors: Boryn Galyna 
Published: March 2023

The article is devoted to the analysis of the ethno-aesthetic component of the cultural approach in the process of preparation of future educators for the management of creative artistic and constructive activity of preschool children. Particular attention is paid to the fact that improving the training of future educators for the upbringing of preschool children is related to the revival of the cultural and educational mission of a higher education institution, establishing those educational relationships that provide for the unity of forms, methods and means of spiritual and creative development of future teachers. It is emphasized that the basis of the cultural approach is the system of value attitude to the social environment, to itself. In modern pedagogical science, the cultural approach is a methodology, which is based on the pedagogy of humanism, it involves the formation of a future personality in the relevant historical and cultural conditions of life, development, education. It has been found that the preparation of future educators of preschool education institutions is a permanent edging process, the content of which is agreed by ukrainian society. At the heart of this process - customs and traditions of the лkrainian people, orientation on national models of folk art. It is clarified that the aesthetization of the educational process in the higher education institution is focused on the use of those forms and methods that contribute to the formation of pedagogical culture of the applicant with the means of art. Ukrainian folk art, penetrating the content of students' learning, provides opportunities for the comprehensive harmonious development of the future tutor, promotes the realization of his creative potential. The procedures for the implementation of the ethno-aesthetic component of the cultural approach during the artistic and constructive activity of education applicants in higher education with the activation of the following characteristics are considered: integrity and sub-sensory (hypersensitivity) of the perception of the world, synergy, imagery, association, sensitivity.
Keywords: cultural approach, artistic and constructive activity, educational process, preschool education institution, ethnosthetic component, professional training, higher education institution, education applicants, preschool children.

Authors: Gavriel-Fried Belle , Serry Meytal , Katz Dana , Hidvégi Dorottya , Demetrovics Zsolt , Király Orsolya 
Published: March 2023

AbstractBackgroundRecovery from mental health and behavioral disorders is classically defined as a reduction in symptoms. More recent definitions see it as a process in which individuals improve their health, wellness and other life domains. The inclusion of gaming disorder (GD) in the 11th International Classification of Diseases in 2019 prompted growing interest in GD. However, relatively little is known about recovery from GD, and there is scant literature describing or assessing its course.ObjectivesThis scoping review was designed to explore the state of the art on recovery from GD (e.g., terminology and measures used to assess recovery, main topics in studies about recovery from GD).MethodsPubMed, Web of Science, and Scopus databases were searched and critically reviewed according to PRISMA guidelines. We included empirical studies in English covering individuals across all age groups who met the diagnostic criteria of GD/internet gaming disorder (IGD) according to valid scales that relate to recovery or any change, and were published before February 2022.ResultsA total of 47 out of 966 studies met the inclusion criteria. Recovery as a concept is not explicitly mentioned in GD studies. Rather, changes in subjects' disorders are described in terms of decreases/reductions in symptom severity, or improvement/increases. These changes are primarily measured by scales that evaluate symptom reduction and/or improvement in GD and other psychopathologies.ConclusionsThe concept of recovery is included in the GD field but is not clearly mentioned or used. Therapists and researchers should aim to promote and integrate the notion of recovery in GD.

AbstractBackground and aimsThe World Health Organization's International Classification of Diseases (ICD-11) includes Compulsive Sexual Behavior Disorder (CSBD), a new diagnosis that is both controversial and groundbreaking, as it is the first diagnosis to codify a disorder related to excessive, compulsive, and out-of-control sexual behavior. The inclusion of this novel diagnosis demonstrates a clear need for valid assessments of this disorder that may be quickly administered in both clinical and research settings.DesignThe present work details the development of the Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI) across seven samples, four languages, and five countries.SettingIn the first study, data were collected in community samples drawn from Malaysia (N = 375), the U.S. (N = 877), Hungary (N = 7,279), and Germany (N = 449). In the second study, data were collected from nationally representative samples in the U.S. (N = 1,601), Poland (N = 1,036), and Hungary (N = 473).FindingsAcross both studies and all samples, results revealed strong psychometric qualities for the 7-item CSBD-DI, demonstrating evidence of validity via correlations with key behavioral indicators and longer measures of compulsive sexual behavior. Analyses from nationally representative samples revealed residual metric invariance across languages, scalar invariance across gender, strong evidence of validity, and utility in classifying individuals who self-identified as having problematic and excessive sexual behavior, as evidenced by ROC analyses revealing suitable cutoffs for a screening instrument.ConclusionCollectively, these findings demonstrate the cross-cultural utility of the CSBD-DI as a novel measure for CSBD and provide a brief, easily administrable instrument for screening for this novel disorder.

Published: March 2023

O presente trabalho teve como objetivo a produção enzimática de um éster com atividade antioxidante (galato de isoamila) por esterificação de ácido gálico e álcool isoamílico em meio de solvente (terc-butanol). Oito lipases comerciais de diferentes fontes (microbianas e animal) foram empregadas na forma livre (extratos brutos) como biocatalisadores. As reações foram conduzidas empregando 0,25 mol L-1 de cada reagente (ácido gálico e álcool isoamílico), agitação mecânica de 240 rpm, 40°C, 4 h de reação e 1000 unidades de atividade enzimática baseada na hidrólise da emulsão de azeite de oliva. Os máximos valores de porcentagem de conversão foram obtidos para as preparações de lipase de Pseudomonas fluorescens – LPF (41,5 ± 5,1%) e de pâncreas suíno – LPP (38,4 ± 2,3%), a preparação de lipase testada com menor custo. A produtividade para estes sistemas de reação foi da ordem de 25 µmoles de ácido gálico consumido h-1 U-1. Estes revelam que a aplicação de uma lipase de baixo custo (LPP) pode ser promissora na produção de ésteres com propriedades antioxidantes, uma importante classe de compostos empregados na área de alimentos e cosméticos.

Health practices refer to individuals' role in maintaining health and preventing diseases (Weldekidan, 2022). The COVID-19 pandemic has dramatically impacted the community, affecting people's lives and health. Adhering to health practices imposed by the Department of Health is vital to prevent the spread of the virus. This study utilized the descriptive quantitative research design aided by a self-made questionnaire. The tool was subjected to Cronbach's Alpha test, obtaining a result of 0.765 for the Lifestyle and 0.826 for the preventive measure. The instrument was distributed via an online platform to one hundred randomly selected residents of San Antonio, Duero, Bohol, from 18 years old and above, to determine their health practices used in preventing the spread of COVID-19 infection. Results revealed that the majority of the respondents had "Very good health practices" in terms of preventive measures; and had "good health practices" in terms of Lifestyle. Data was further subjected to the Spearman rho test and chi-square test and revealed a significant relationship between the Age and level of health practices; and between the zonal where the respondents live and the level of health practices.
