Many research studied that realistic mathematics education (RME) can be an alternative solution to students’ difficulties in learning mathematics. Various forms of technology additionally are further employed to support students' mathematical achievements. However, research on the implementation of virtual learning environments (VLE) with the RME approach is still lacking. The main goals of this research were to create an instructional process of virtual learning environments on realistic mathematics education to improve seventh graders' mathematical modeling abilities and to examine the effect of designs on mathematical modeling ability. Theory of realistic mathematics education and virtual learning environment literature were integrated. The design model developed was verified by experts to be tested. The pre-test / post-test test method was carried out to see the effectiveness of the design. The sixty-seventh graders from a secondary school in North Sumatera were selected as samples. The instructional process developed consists of four stages, namely (1) purposing contextual problems, (2) defining situations from contextual problems, (3) solving problems individually or in groups, and (4) reviewing and comparing solutions. The developed virtual learning environment consists of 5 components, namely (1) users management, (2) content and activities management, (3) resources management, (4) visualization and communication management, and (5) evaluation and assessment management. The mathematical modeling ability concerning experimental group students is significantly higher after being taught through a realistic mathematics education instructional process via a virtual learning environment. Comparison of the experimental group with the control group also showed the same results.

Sexually dimorphic claws predict courtship and mating sequence in the intertidal oribatid mite Fortuynia atlantica (Acari, Oribatida)
Authors: Pfingstl Tobias , Kerschbaumer Michaela
Published: July 2022

Fortuynia atlantica, is a sexually dimorphic oribatid mite and although observations are lacking, direct sperm transfer is assumed. We found an additional sexual dimorphism in claw morphology, with females showing relatively smaller and more curved claws, which may point to a possible direct contact during reproduction. Males possess lateral notogastral projections and these could be used as ‘handles’ by the females in the course of some kind of mating. The claws of the females are large enough to embrace the male’s lateral projections and the females’ first legs are long enough to attach to the males’ body from behind without hampering its movement with the rest of the legs. Based on these indications, we propose a hypothetical mating scenario where the male attracts females via pheromones, the female approaches from behind and clasps with the claws of the leg I the ’handles’ of the male. This stimulates the male to deposit a stalkless spermatophore and in a final step the male leads the still attached female over the spermatophore to absorb it. Observation of living specimens is ultimately necessary to verify the existence of the proposed or any other mating behaviour.
SELF-EFFICACY TO OVERCOME EXERCISE BARRIERS IN INDIVIDUALS WITH CANCER-RELATED LYMPHEDEMA
Authors: Buchan J. , Janda M. , Box R. , Rogers L.Q. , Hayes S.
Published: July 2022

Although cancer survivors are recommended to exercise, they may lack confidence (self-efficacy) to be active. This research aimed to measure exercise barriers and related self- efficacy in individuals with cancer-related lymphedema as well as examine relationships between self-efficacy and participant characteristics. A cross-sectional survey was under- taken in individuals with cancer-related lymphedema using a validated 14-item Likert scale assessing self-efficacy to overcome general and lymphedema-specific exercise barriers (0%=not at all confident, 100%=extremely confident).
Demographic, medical and lymphedema data were also collected. Of 109 participants (52% response), 79% (n=86) had breast cancer-related lymphedema. Participants were found to be moderately confident to exercise when facing general (48% [95% CI: 44, 52]) and lymphedema-specific exercise barriers (51% [95% CI: 47, 55]). Participants who were female, sedentary (p<0.05), had lymphedema for ≥2 years, and reported greater symptom burden (p<0.05) recorded lower general exercise barriers self- efficacy. Lower lymphedema-specific exercise barriers self-efficacy was reported by individuals who were sedentary, had cancers other than breast, and higher symptom burden.
These findings suggest general and lymphedema-specific barriers challenge exercise confidence in those with cancer-related lymphedema, and strategies tailored to improve confidence in overcoming exercise barriers are warranted. Supporting individuals to be sufficiently active during and following cancer treatment should consider behavior change strategies tailored to the unique needs faced by
individuals with lymphedema.
Technology – Military Art Connections in the Military Training Process
Authors: Grigoraş Constantin
Published: July 2022

The issue of the technological revolution and its impact on military operations and, implicitly, on the force training process, in the current conditions, is a highly timely, interdisciplinary research topic at the confluence of technical, military, and economic sciences. The increasing complexity of weapons systems under the technological evolutions generates the need to adapt training processes both in terms of the learning methods and of the techniques used, but above all, in terms of the technologies applicable to force training where, a multitude of opportunities have been generates by the advent of the computer. The new technologies have led to a compression of time and a widening of the area of confrontation and a diversification of tactics, techniques, and procedures used in military conflicts, which requires an appropriate response in the area of military operations training. The essence of this paper is to find the most effective ways of training military forces by studying the impact advanced technologies have on this phenomenon.
Evolution of Conflicts, Strategies, and High-Precision Weapon Systems
Authors: Oprean Georgel
Published: July 2022

It’s been a few decades since military operations success has become difficult to define. During the Cold War, the outcome of a war between relatively symmetrical forces was predictable and the adversary was forced to admit defeat. In recent decades, the paradigm has changed radically in the political, diplomatic, and military domains, against the background of a geopolitical context characterized by complexity and instability, where the competitive struggle for hegemony between states is fierce and the proliferation of new risks, asymmetric, and hybrid threats requires the adaptation of strategies and capabilities to the new operational environment. New high-precision search-and-rescue, missile, communications and computing systems are a clear technological opportunity, and their ownership and usage is a real prerequisite for success in military operations. These sophisticated, integrated and synchronised technologies are, and will remain in the future, vectors of strategic deterrence because of their ability to detect and engage targets with maximum accuracy and effectiveness.
Legal Approach to the Democratic Control of the Armed Forces
Authors: Stoian Alexandru
Published: July 2022

The existence of contemporary states is directly conditioned by the ways of effectively defending the values, institutions and state resources. The organization and endowment of the armed forces is the expression of the will of the holders of political power and therefore ensuring the democratic character of the control of the armed forces becomes an imperative of today’s global society, an imperative that is achieved through legal means. The process of militarization of contemporary states is supported by the legal framework that establishes the extent and type of political and administrative control that is exercised during this process. An important role in this legislative context is played by the constitution, the fundamental law of each state, which sets out the general principles and modalities for ensuring democratic control of the armed forces. Whether it is a direct control exercised by the people through a referendum or another similar means of expressing the will in connection with military matters of national interest, or it is an indirect control, carried out by the representative authorities, whose members are elected to represent the will of the people, democratic control of the armed forces is a matter of current
Hypothesising in Contemporary Organisational Management Research. What Really Matters?
Authors: Todăriţă Elida , Porancea-Răulea Andreea , Ranf Diana , Badea Dorel
Published: July 2022

Management is an economic science and more than ever, temporal, as a direct effect of the level of social development, with many interdependencies with other fields of knowledge. Generically said, studies and research in the field of organisational management involve a high level of difficulty compared to other types of sciences because they primarily investigate aspects related to the soft component of the organisation, the human resource. The results, operationalised through the design and implementation of decisions, are achieved by people, for people, and people are involved in the (micro or macro) organisational universe with different experiences and expertise, different attitudes, different expectations, transforming other types of resources. It is difficult to translate purely qualitative aspects, which can be extracted from an organisational framework often by observation, into quantitative contexts that support the transformation of conclusions into judgements of principle value. In this context, the article examines the role, importance and usability of the hypothesis as a management tool. Starting from the highlighting of topical issues in the field of management science, an attempt is made to answer the following questions: in what situations can hypotheses be used? what are the application peculiarities and, subsequently, the advantages and disadvantages? what established typologies have been highlighted in the investigation of management issues? The theoretical observations are doubled in significance by a case study based on the use of the Competing Hypotheses Model (CHA). To summarize, the quality of the conceptual representations and semantics of the construction of a working hypothesis can bring us closer or further away from the organisational reality of interest, with direct effects on the relevance and effects of the activity undertaken.
How Smart Power Influences Economic
Power – A Brief Overview on the
Sino-American Tariff War from 2018 to 2021
Authors: Murea Maria Mirona , Nica Lenuţa Ella , Georgescu Aimée Andrada Theodora
Published: July 2022

Today’s Transnational Companies (TNCs) have gained an increased role in the diplomatic realm, due to
recent globalization developments. International relations focus around trade liberalization and creation of
deep interdependencies limiting the use of hard power as a coercive method. The 1990’s, Joseph’s Nye concept
of soft power has gained importance in the political and economic diplomatic negotiations, influencing also
the TNCs internationalization decisions, leading to a deeper market globalization. The speed of
globalization development and dynamics of international relations brought to the forefront a new type of
power: smart power. Today’s world is dominated by two major economic actors: USA and China, and their
sensitive bilateral relations has brought into light a modern Thucydides’ Trap. To avoid a potential war,
each country used different smart power strategies: China had a long run-oriented strategy with smaller gains,
while the USA aimed for a big impact in a short period of time, obtaining opposite results influencing the
global business environment, and the TNCs performances worldwide. The research objective is to analyze
the impact of the two opposite smart power strategies on the main TNCs by country, comparing their
revenues, profits and changes in profit, of the first top 10 rankings presented in Forbes 500 during a time
period starting 2018 (since the “tariff war” began) to 2021 (present). The main results emphasized that
economic power is divided among TNCs from the USA and China, despite the existence of tense diplomatic
and economic relations.

Published: July 2022

El cambio climático es un problema de interés público a escala global. Por sus dimensiones espaciales y temporales, este fenómeno requiere la construcción de una perspectiva global amplia para ser legible. Sin embargo, ¿cómo se manifiesta su estudio en lo local? Este artículo explora algunas particularidades de las ciencias del clima practicadas en Chile a partir de entrevistas y observaciones con integrantes del Centro de Ciencias del Clima y la Resiliencia. El artículo argumenta que las ciencias del clima en Chile presentan una condición híbrida, entre vida local y pertenencia global. Para ello, explora la tensión entre las condiciones locales de investigación en Chile y el estudio global del cambio climático en torno a dos aspectos centrales: el uso local de dispositivos de visualización y la organización de las comunidades epistémicas que estudian el clima. Mostramos que existen condiciones locales que afectan la forma de producir conocimiento. Esta “cultura de lo inacabado” permea y da forma al conocimiento producido en Chile. Concluimos discutiendo el lugar de las ciencias locales en la globalidad del cambio climático.
Effects of State Degeneration in 3D Quantum Lenoir Engine Performance
Authors: Fahriza Ade , Sutantyo Trengginas E. P.
Published: July 2022

We study the performance of the quantum Lenoir engine using single-particle confined within the cubic potential. In 3D potential structure, particles degenerate into multiple states at identic energy level which occurs on the excitation state of the particles. Deliberating the degeneration effects, the confined particle has possibility to produce more energy efficiency as engine’s working substance. The particle is able to freely move in three directions of x, y, and z-axis simultaneously, which gives three degrees of freedom to the particle in the cubic potential. By limiting to two eigen states, a basic explanation to the condition of the particle was provided. The efficiency of 3D quantum Lenoir engine is better than the classical model of the Lenoir engine despite the similarity in the formulation. Moreover, we also consider the efficiency comparison between the 3D model, with some state modifications, and the 1D efficiency of the quantum Lenoir engine. As expected, degeneration of the particle’s states plays a role in the enhancement of the quantum Lenoir engine’s efficiency. Moreover, we also derived the power output of the 3D quantum Lenoir engine. Thus, this study clearly gives a sight of the performance of quantum Lenoir engine model in the 3D manner.

Presented in this paper is a public service data base for Kirkuk city. The data base is based on dividing the town into a number of main districts and coding the zones and neighborhoods in each of the main distracted. This coding would help in constructing a comprehensive indexing system for the available services in the Nations zones of the city. The system may then be utilized in the plans of future expansion of the city in order to reduce discrepancies in the distribution of public services. It has been found that the block system is better and more suitable than other existing methods. It can be implemented easily by governmental establishments that are involved in such services uses geographical information system (GIS).

Published: July 2022

In this work four types of wastewater namely domestic, dairy, sugar and textile are used to perform statistical analysis. These wastes are treated by extended aeration system. Inlet and outlet COD and S.S are used to make the statistical correlation for F/M range of 0.1-1. The results showed that the relation between COD and SS is linear for domestic, dairy and sugar waste having a correlation coefficient 0.9323, 0.8774 and 0.8698 respectively. The relation is of third degree for textile waste with correlation coefficient of 0.557 due to chemicals and heavy metals. The relation between F/M and COD for all wastes is linear. To predict COD value leaving treatment plant using F/M and SS values which are allowed to be thrown to the water body, Duncan test was made depending on outlet COD and SS which show that extended aeration is not suitable for textile waste.
Design and Implementation of a Cpld-Based Multilevel Inverter Depending on a Complex Programmable Logic Device (CPLD)

Published: July 2022

A complex programmable logic device (CPLD) based multilevel inverter has been designed and implemented. The design involves three main parts. The first part is the switching angle generator (SAG), which determines the switching angles from an optimized primitive angle. The second part is the switching pulse generator (SPG), which controls the drive circuit of the inverter. The timing circuit is the third part, which provides the necessary timing for both SAG and SPG. Implementing both SAG and SPG using a CPLD device mean high speed cycle time. Hence an accurate timing for the switching angles is obtained compared to other procedures that uses software for calculating and generating the switching angles, such as microcontroller. MATLAB work space has been used to acquire and analyze the inverter output via the PC sound card. Results of the implemented inverter staircase output voltage, as well as the output frequency spectrum are obtained.
Predicting and rationalizing the Soret coefficient of binary Lennard-Jones mixtures in the liquid state

Published: July 2022

The thermodiffusion behavior of binary Lennard-Jones mixtures in the liquid state was investigated by combining the individual strengths of non-equilibrium molecular dynamics (NEMD) and equilibrium molecular dynamics (EMD) simulations. On the one hand, boundary-driven NEMD simulations are useful to quickly predict Soret coefficients because they are easy to set up and straightforward to analyze. However, careful interpolation is required because the mean temperature in the measurement region does not exactly reach the target temperature. On the other hand, EMD simulations attain the target temperature precisely and yield a multitude of properties that clarify the microscopic origins of Soret coefficient trends. An analysis of the Soret coefficient suggests a straightforward dependence on thermodynamic properties, whereas its dependence on dynamic properties is far more complex. Furthermore, a limit of applicability of a popular theoretical model, which mainly relies on thermodynamic data, was identified by virtue of an uncertainty analysis in conjunction with efficient empirical Soret coefficient predictions, which rely on model parameters instead of simulation output. Finally, the present study underscores that a combination of predictive models and EMD and NEMD simulations is a powerful approach to shed light onto the thermodiffusion behavior of liquid mixtures.

For sustainable storage of electrical energy, all-organic batteries based on redox-active polymers promise to become an alternative to conventional lithium ion batteries. Yet, polymers can only contribute to the goal of an all-organic cell as electrodes or as solid electrolytes. Here, we replace the electrolyte with a sustainable deep eutectic solvent (DES) composed of sodium bis(trifluoromethanesulfonyl)imide (NaTFSI) and N-methylacetamide (NMA), while using poly(2,2,6,6-tetramethylpiperidin-1-yl-oxyl methacrylate) (PTMA) as cathode. The successful combination of a DES with a polymer electrode is reported here for the first time. The electrochemical stability of PTMA electrodes in the DES at the eutectic molar ratio of 1:6 is comparable to conventional battery electrolytes. More viscous electrolytes with higher salt concentrations can hinder charging and discharging at high rates. Lower salt concentrations on the other hand lead to decreasing capacities and faster decomposition. The used eutectic mixture of 1:6 is best suited uniting high stability and moderate viscosity.

Published: July 2022

Fruto de uma pesquisa vinculada à Universidade Federal de Mato Grosso do Sul – UFMS, Câmpus Naviraí, o objetivo do artigo consiste em compreender a relação entre as políticas públicas propostas para a Educação Infantil e o discurso presente no critério para ingresso nesse espaço na rede municipal de educação local. Questionários semiestruturados foram aplicados aos gestores das instituições de atendimento à infância, escolas de Ensino Fundamental que ofertam pré-escola e uma entrevista foi realizada com a Coordenadora de Área da Gerência de Educação (GEMED). Da análise dos dados, foi possível afirmar que: 1) o número de crianças que, atualmente, necessitam ter acesso à Educação Infantil em Naviraí/MS é significativo; 2) diante disso, os Cieis se baseiam em lista de espera para atender a demanda; 3) quando a situação é emergencial um critério mais frequente é dar preferência para a criança cuja mãe é trabalhadora, dado que reforça a visão assistencialista.
NARRATIVAS AUTOBIOGRÁFICAS DE PROFESSORAS SOBRE CRIANÇA(S) E INFÂNCIA(S) NOS ESPAÇOS DE EDUCAÇÃO INFANTIL NO SERTÃO CEARENSE
Authors: Dos Anjos Ana Maura Tavares
Published: July 2022

Este trabalho objetiva refletir sobre as concepções de professoras acerca do conceito de criança(s) e infância(s) e as possíveis implicações da Sociologia da Infância na prática pedagógica docente. Nesse sentido, interrogamo-nos sobre as concepções de professoras de educação infantil sobre infância e criança, tendo em vista que o entendimento de tais conceitos são prerrogativas que permeiam e subsidiam a práxis pedagógica da professora e do professor de educação infantil. Para isso, dialogamos sobre infância(s) e criança(s) à luz de Sarmento (2005), Corsaro (2002), dentre outros autores, sua relação com as políticas de educação infantil e a BNCC (2017). O estudo, qualitativo, teve o corpus de análise constituído de narrativas de 8 (oito) professoras e revelou que as concepções de criança(s) e de infância(s), apresentadas pelas professoras, corroboram as prerrogativas legais e os pressupostos da Sociologia da Infância.

Published: July 2022

O artigo debate o crescimento do número de evangélicos no Brasil e na América Latina apontando suas repercusões nas políticas públicas e suas crescente influência na Educação latino americana, especialemente após a eleição presidencial de 2018 no Brasil.  Destacamos que a ideologia política neopentecostal parece ajustar-se às reformas ultraliberais formulada pelas políticas da chamada Escola de Chicago inclui privatizações, desregulamentação ambiental, flexibilização dos direitos trabalhistas e a terceirização de serviços públicos, aprofundando a ideia do Estado como “prestador de serviços”, abandonando-se por gradualmente preocupações sociais, ambientais e políticas inclusivas, inclusive na educação.
Relações étnico-raciais: uma tarefa para a formação de professores
Authors: Andrade Genilsa Soares de , Bisol Benedetta
Published: July 2022

O artigo apresenta os resultados de um estudo exploratório sobre as relações étnico-raciais como componente curricular na formação de professores, focando especialmente no problema da discriminação dos negros no Brasil e da inclusão no currículo da história e da cultura afro-brasileira. Examinamos os currículos de oito cursos de licenciatura em pedagogia de Instituições de Ensino Superior (IES) da região Centro-Oeste do Brasil. Os dados sugerem uma disparidade significativa entre formação docente em instituições públicas, mais consistente e articulada, e em privadas, aparentemente mais limitada e incompleta. Contudo, não foi possível apresentar uma avaliação conclusiva, dada a escassa quantidade de informações disponibilizadas pelas IES privadas investigadas, então sugerimos uma nova pesquisa que considere um número maior de instituições, com o objetivo de verificar o peso real da disparidade de formação entre universidade pública e privada, assim como abordar especificamente os conteúdos da formação docente sobre relações étnico-raciais.
