One of the efforts of an educator in creating a conducive teaching and learning atmosphere or class that gives a pleasant impression for students in listening and understanding the content of the subject matter explained by a teacher. Not infrequently also in the learning process there are various kinds of problems in children ranging from falling asleep during class hours, the lack of neatness of students, lack of uniform attributes, for example not cursing ties, belts and socks. In more serious problems, sometimes students can act out of bounds such as student delinquency and lack of student courtesy to the teacher. The problems arise from internal and external factors. Strategies in creating an effective and conducive learning environment, the role of the teacher here is not the same as being required to teach a material but the teacher must be able to control and coordinate the class and students, so it is necessary for the teacher's role in it to be able to direct students to things that better reflect students such as biological children and pay attention to behavior and a teacher must be fair in making decisions so that there is no jealousy among other students. A teacher should pay more attention to students like their parents. The approach taken by a teacher is a behavioristic, cognitive, and humanistic approach.

Education is an effort that aims to develop a complete human being which includes three aspects, namely cognitive, affective and psychomotor aspects. To be able to achieve the educational goals which consist of these three aspects, it is necessary to develop various aspects of personality, including intellectual, social, and emotional. Individuals have two intelligences, namely thinking (intellectual intelligence) and feeling (emotional intelligence). Behaviors that refer to indications of low emotional intelligence of students such as not going to school without explanation, arriving late, fighting, saying rude / dirty words, not listening to the teacher during class, lying and fighting against the teacher. This study aims to determine the increase in students' emotional intelligence through a transactional analysis approach. The method used in this study is the Classroom Action Research method with 8 students as the research subject indicated low self-emotional intelligence.

This study aims to explore the concept of God for the mystics and its contribution to religious tolerance in Indonesia. The questions to be answered in this research are (1) What is the concept of God for the Mystics ?, (2) What and how does the concept contribute in relation to religious tolerance, especially in Indonesia. This research is a qualitative research. The data source comes from the literature. The analysis method uses a hermeneutic which consists of elements of description and interpretation. The results of this study found that the God of the mystics is an impersonal God, in the sense of not being described. Another reality besides Him is His image. He is One and the cause of everything. He can only be found or approached by those who have purified themselves. The contribution of the mystics to the tolerance of the religious community lies in the similarity of their conception of God, namely as God who is undefined. This similarity can be used as a meeting point that allows the Religious community to be more inclusive and enlarge the equation, not the other way around

Today's realities have led to the fact that in various sources they are actively considering the issue of finding options for improving the system of repair and restoration of weapons and military equipment in the Armed Forces of Ukraine and improving (modernization) of mobile means of maintenance and repair of anti-aircraft weapons. Of course, in most cases, the subject of these works is the consideration of means of maintenance and repair of automotive equipment, somewhat less often of armored weapons and equipment, and, unfortunately, there are almost no works related to mobile means of maintenance and repair of missile and artillery weapons.
The previous article was devoted to the analysis of the composition of mobile means of maintenance and repair of missile and artillery weapons in the Armed Forces of Ukraine and the procedure for their use. The issue of improving the existing mobile means of maintenance and repair of weapons of the missile and artillery nomenclature was also considered. The material presented in it created the conditions for justifying in this article the technical requirements for the properties of mobile means of maintenance and repair of missile and artillery weapons. In the opinion of the authors, it is appropriate to substantiate such properties as maintainability, technological equipment and cost-effectiveness of repair samples of missile and artillery weapons.
The substantiation of the above technical requirements will create all the prerequisites for the development of recommendations necessary for the development of mobile means of maintenance and repair of modern missile and artillery weapons, the main ones of which may be - recommendations regarding the basic chassis and body of a van (container), regarding the equipment and specialization of the workshop and regarding the functional filling and calculation of the workshop.

The history of small-sized, low-speed unmanned aerial vehicles, in contrast to the history of unmanned aerial vehicles, is not counted for half a century, but only for two dozen years. The first publications devoted to small-sized and low-speed unmanned aerial vehicles were published after 2008. The number of publications on the specified subject significantly increased in 2017-2018. It is during this period that military operations using small-sized and low-speed unmanned aerial vehicles become widespread. As an example, we can mention the attacks on the oil refinery in Saudi Arabia in September 2019, the attack on the airport in the city of Jizan in the same Saudi Arabia in July 2020, the attacks on the Russian air base in the Syrian city of Khmeimi in 2019-2020.
Almost every day, from the regions of the planet where armed conflict is taking place, there are reports of the destruction of storage places of weapons and means of destruction, which affects the course of armed conflicts. It is significant that unmanned aircraft are increasingly being used to destroy weapons. The article highlights the factors that determine the effectiveness of the use of unmanned aerial systems for the destruction of weapons storage sites, and predicted dynamic changes in these factors.
The rapid development of microelectronic technologies, which is currently observed, became the basis for the improvement of unmanned aircraft systems, the expansion of the range of tasks performed by unmanned aircraft, the emergence of new classes of devices and the improvement of the tactics of their use. The rapid development of microelectronics is also considered from the point of view of confirming Moore's law, forecasts for the near future, clarifications of the law for the present time, clarifications of forecasts for the next 15 years. Conceptually, the opinions of the authors regarding the minimization of losses of weapons of destruction are presented, the basis of which are their own observations of the statistics of losses from storage sites of weapons of destruction of the Armed Forces of Ukraine for the period from 2003 to 2018, the causes of losses.

From Society to Shehui : The Early Configuration of a Basic Concept in Modern China
Authors: LI Gongzhong
Published: July 2023

Abstract: As a traditional term used in ancient Chinese, shiehwui mainly implied the gatherings and meetings related to folk festivals for the worship of and making offerings to shie , the gods of soil. The manifestation of shiehwui frequently was the
target of condescension or outright condemnation from the government or Confucian elites. During the early dissemination of the western concept of Society into China, one factor that facilitated its entry was the Christian missionaries’ knowledge of traditional Chinese shie
and hwui , especially the secret societies, which they applied to their translations from English into Chinese. When the modern concept of shakai (written as , the same Chinese characters), formulated in Japan, was imported into Chinese at the turn of the 20th century, it became
blended with the old word of shiehwui, and found a connection to the daily life experience of the lower classes in traditional China. As a result, the new concept of Shehui in modern China possesses two kinds of connotations. On the one hand, it points toward the new direction
of historical changes. On the other hand, it still retains the associations of condescension, dissatisfaction and anxiety that inform the perspective of the ruling class toward this term.
The Arcanum of Life – On Hegel’s Idea of Life
Authors: GUO Guanyu
Published: July 2023

Abstract: This paper investigates Hegel’s idea of life, which is on the one hand significant to the research of the dynamic structure of Hegelian absolute idea and on the other hand provides a relevant philosophical foundation for our current exploration of life. In
this paper, the research on the idea of life is mainly based on Hegel’s Science of Logic and is divided into two parts, namely an argumentative reconstruction of the moments of the life-idea and an interpretation of its role in the inner-logical process of the idea itself. Through
the study of these two dimensions, this paper shows that the complex logical structure of the life-idea is, as claimed by Hegel, in its forming activity, in its negative unity, the only one unified process and plays four relevant roles in the inner-logical construction of the idea itself,
namely in the core concept of Hegel.

Authors: Fillol Mazo Adriana , Martín López Miguel Ángel
Published: July 2023

El cumplimiento del derecho a la alimentación precisa de acciones que se instrumenten a partir de un marco de análisis integrado y coherente que permita abordar de forma sistemática tanto las obligaciones internacionales establecidas a nivel de tratados, como los diversos acuerdos alcanzados en documentos estratégicos (como los Objetivos de Desarrollo Sostenible). Para reforzar el cumplimiento de este derecho y paliar las deficiencias del sistema de gobernanza alimentaria se han elaborado indicadores, tanto en el plano universal como en el regional, que ofrecen pautas o herramientas para realizar el diagnóstico de la situación del derecho a los efectos de evaluar y medir el cumplimiento a la alimentación. En este trabajo nos hemos centrado en analizar la matriz de indicadores que se proponen en el marco del sistema interamericano de derechos humanos y se ha prestado especial atención al estudio de aquellos indicadores que pueden resultar más favorables para proteger y promover el derecho a la alimentación de la población rural, entendiendo por tal a los agricultores familiares/locales, a las personas sin tierra y a los pueblos indígenas.

Published: July 2023

The role of intangible assets such as intellectual capital promoting corporate competitiveness and further shareholders’ value has attracted attention in the finance literature. This study investigated intellectual capital efficiency as a source of creating shareholders’ wealth in Nigeria. To achieve the study's aim, correlational research design was adopted. The study’s data were collected from content analysis of financial statements of listed service companies in Nigeria. The sample used in this study includes 17 service firms listed on the Nigeria Exchange Group from 2011 to 2022. The VAIC model was utilized to estimate intellectual capital. Descriptive statistics were conducted while some diagnostic tests were piloted before the regression analysis. The random effect regression model was used to verify whether the studied variables impact shareholders’ wealth of listed service companies in Nigeria. Findings indicated that value added intellectual coefficient as a measure of intellectual capital has a significant positive association with shareholders’ wealth. Results further revealed that human capital efficiency, relational capital efficiency and capital employed efficiency (as components of intellectual capital) are significantly and positively associated with shareholders’ wealth while structural capital efficiency has a positive but not significant relationship with shareholders’ wealth creation. The study concludes that efficient management of intellectual capital can enhance shareholders’ wealth in listed service companies in Nigeria and recommends amongst others that firms should make strategic plans regarding intellectual capital and intangible assets as it can increase corporate competitive advantage.

Aim: To examine the changes in the anxiety levels of pregnant women in the last two years, since the onset of the COVID-19 pandemic and to determine how sociodemographic characteristics have affected these levels.

Materials / Method: State-Trait Anxiety Inventory (STAI) was given to 400 low-risk pregnant women visiting the antenatal outpatient clinic within a two years interval regardless of their gestational age. Besides the anxiety inventory, the sociodemographic characteristics of the participants were also noted. The results were evaluated at the end of two years.

Results: Gestational week, working status, whether the pregnancy was planned or not, and partner support were not statistically significant between groups(p|>0.001). The averages of state and trait anxiety of pregnant women were higher at the beginning of the pandemic than the pregnant women were after two years period(p=0,000,p=0,038, respectively). While there was no difference related to age at the beginning of the pandemic, the level of trait anxiety increased as the mother’s age increased in the period after two years(p=0.047). The anxiety level of primigravidas was found to be higher compared to the multiparas. Pregnant women who were working while the social restrictions were being imposed due to the pandemic had lower anxiety levels than those who were not(p=0.049).

Conclusion: Even though working during social restrictions seems quite risky because of the disease transmission, it has a positive effect on reducing the level of anxiety in pregnant women with social support. Therefore, psycho-social support programs for pregnant women should be kept ready in major disasters.

Published: July 2023

We present a new selection of 358 blue compact dwarf galaxies (BCDs) from 5000 square degrees in the Dark Energy Survey, and the spectroscopic follow-up of a subsample of 68 objects. For the subsample of 34 objects with deep spectra, we measure the metallicity via the direct T

e
method using the auroral [O iii]λ 4363 emission line. These BCDs have an average oxygen abundance of 12+log(O/H) = 7.8, with stellar masses between 107 and 108
M
⊙ and specific star-formation rates between ∼10−9 and 10−7 yr−1. We compare the position of our BCDs with the mass–metallicity (M–Z) and luminosity–metallicity (L–Z) relation derived from the Local Volume Legacy sample. We find the scatter about the M–Z relation is smaller than the scatter about the L–Z relation. We identify a correlation between the offsets from the M–Z and L–Z relation that we suggest is due to the contribution of metal-poor inflows. Finally, we explore the validity of the mass–metallicity–SFR fundamental plane in the mass range probed by our galaxies. We find that BCDs with stellar masses smaller than 108
M
⊙ do not follow the extrapolation of the fundamental plane. This result suggests that mechanisms other than the balance between inflows and outflows may be at play in regulating the position of low-mass galaxies in the M–Z–SFR space.

Accreting white dwarfs (WDs) in cataclysmic variables (CVs) show short-period (tens of minutes) brightness variations that are consistent with nonradial oscillations similar to gravity (g) modes observed in isolated WDs. The dwarf nova GW Librae was the first CV in which nonradial oscillations were observed and continues to be the best-studied accreting WD displaying these pulsations. Unlike isolated WDs, accreting WDs rotate rapidly, with spin periods comparable to or shorter than typical low-order oscillation periods. Accreting WDs also have a different relationship between their interior and surface temperatures. The surface temperature of an accreting WD varies on a months-to-year timescale between dwarf nova accretion events, allowing study of how this temperature change affects g-mode behavior. Here we show results from adiabatic seismological calculations for accreting WDs, focusing on low-order (ℓ = 1) modes. We demonstrate how g-modes vary in response to temperature changes in the subsurface layers due to a dwarf nova accretion event. These calculations include rotation nonperturbatively, required by the high spin rate. We discuss the thermal history of these accreting WDs and compare the seismological properties with and without rotation. Comparison of g-mode frequencies to observed objects may allow inference of features of the structure of the WD such as mass, surface abundance, accretion history, and more. The variation of mode frequencies during cooling after an outburst provides a novel method of identifying modes.

We use medium- and high-resolution spectroscopy of close pairs of quasars to analyze the circumgalactic medium (CGM) surrounding 32 damped Lyα absorption systems (DLAs). The primary quasar sightline in each pair probes an intervening DLA in the redshift range 1.6 < z
abs < 3.5, such that the secondary sightline probes absorption from Lyα and a large suite of metal-line transitions (including O i, C ii, C iv, Si ii, and Si iv) in the DLA host galaxy’s CGM at transverse distances 24 kpc ≤ R
⊥ ≤ 284 kpc. Analysis of Lyα in the CGM sightlines shows an anticorrelation between R

A Past Episode of Rapid Tidal Evolution of Enceladus?
Authors: Ćuk Matija , El Moutamid Maryame
Published: July 2023

Saturn possesses a dynamically rich system containing numerous moons and impressive rings. Whether the rings of Saturn are much younger than the planet itself has been a long-standing open question; more recently a young age has been proposed for some moons. The recent detection of the fast orbital evolution of Rhea and Titan strongly suggests a highly frequency-dependent tidal response of Saturn, possibly through the excitation of inertial waves within the planet’s convective envelope. Here we show that resonance locking to inertial waves cannot explain the dynamical structure of the Saturnian system or the current tidal heating of Enceladus. On the other hand, both the observations and our modeling results indicate that the system is not consistent with evolution under equilibrium tides. We propose that the system’s architecture can best be explained by a relatively high “background” tidal response coupled with discrete resonant modes. In this view, only Titan may be in a true long-term resonance lock with a tidal mode of Saturn. Rhea is most likely currently experiencing a transient period of fast tidal evolution as it passes through a mode, rather than being locked into it. Assuming that Enceladus went through a temporary period of fast tidal evolution, we can reproduce its present resonance with Dione and satisfy other dynamical constraints. Additionally, we conclude that the long-term tidal response of Saturn to Tethys must be weaker than expected from frequency-independent tides, as already found by observations.
Rating of the mobility of Military Logistic Vehicles Used in the Polish Armed Forces
Authors: Wiejak Grzegorz , Grzelak M. , Mroczek R.
Published: July 2023

Mobility of military vehicles is a key element of military transport and it guarantees safety of the logistic system of the Armed Forces. The aim of this article is to compare medium-load and high-mobility means of transport belonging to the Polish Armed Forces and to identify the vehicle with the best parameters. The Analytic Hierarchy Process method was used for this, and this paper approximates its assumptions and process. Seven vehicles currently in use by the Polish Armed Forces were compared. As a result of the analysis, a hierarchy of the studied vehicles was established, ranking them from the highest to the lowest rated. The paper allows to assess whether the currently purchased Jelcz 442.32 is a good choice in the procuring policy of the Polish army.

Authors: Tong Ping , Zhang Qunjiao
Published: July 2023

This paper is concerned with the existence of solutions to the Caputo fractional differential inclusion of $ 1 < \alpha < 2 $ with initial and impulsive boundary conditions. A novel existence result is presented based on the fixed-point theorem of Dhage for multi-valued operators with some assumptions. Finally, two examples are provided to explicate the applicability of the main result.
Some results on the space of bounded second κ-variation functions
Authors: Ereú Jurancy , Marchan Luz E. , Pérez Liliana , Rojas Henry
Published: July 2023

In this paper, we prove that if a globally Lipschitz non-autonomous superposition operator maps the space of functions of bounded second $ \kappa $-variation into itself then its generator function satisfies a Matkowski condition. We also provide conditions for the existence and uniqueness of solutions of the Hammerstein and Volterra equations in this space.
Existence and uniqueness of radial solution for the elliptic equation system in an annulus
Authors: Wang Dan , Li Yongxiang
Published: July 2023

This article discusses the existence and uniqueness of radial solution for the elliptic equation system

   \begin{document}$ \left \{ \begin{array}{ll} -\triangle u = f(|x|, \ u, \ v, \ |\nabla u|), \; \; x\in \Omega, \\[10pt] -\triangle v = g(|x|, \ u, \ v, \ |\nabla v|), \; \; x\in \Omega, \\[10pt] u|_{\partial \Omega} = 0, \; v|_{\partial \Omega} = 0, \end{array} \right. $\end{document}

where $ \Omega = \{x\in \mathbb{R}^{N}:\; r_1 < |x| < r_2\}, \; N\ge 3, \; f, \; g:[r_1, \; r_2]\times \mathbb{R}\times \mathbb{R}\times \mathbb{R}^+\to \mathbb{R} $ are continuous. Due to the appearance of the gradient term in the nonlinearity, the equation system has no variational structure and the variational method cannot be applied to it directly. We will give the correlation conditions of $ f $ and $ g $, that is, $ f $ and $ g $ are superlinear or sublinear, and prove the existence and uniqueness of radial solutions by using Leray-Schauder fixed point theorem.
Stability and bifurcation of a delayed diffusive predator-prey model affected by toxins
Authors: Wu Ming , Yao Hongxing
Published: July 2023

In this work, a diffusive predator-prey model with the effects of toxins and delay is considered. Initially, we investigated the presence of solutions and the stability of the system. Then, we examined the local stability of the equilibria and Hopf bifurcation generated by delay, as well as the global stability of the equilibria using a Lyapunov function. In addition, we extract additional results regarding the presence and nonexistence of non-constant steady states in this model by taking into account the influence of diffusion. We show several numerical simulations to validate our theoretical findings.

A Virtual Linguistic Landscape Analysis of Higher Education Institutions and Their Use of Pronouns of Address in the Hispanic and Lusophone World
Authors: Guarin Daniel , Cardoso Larissa Oliveira
Published: July 2023

The use of space, both physical and virtual, has been extensively studied in relation to language, with many researchers considering it a determining factor. This chapter investigates the virtual linguistic landscape (VLL) of universities in ten Hispanic countries and five Portuguese-speaking countries to examine the use of pronouns of address (PoA) on their digital platforms. With the exponential increase in communication through digital means in recent years, computer-mediated communication has become a relevant topic in understanding human interaction through virtual devices. In this study, the authors specifically analyze the use of second-person singular pronouns in the VLL of higher education institutions in Hispanic and Portuguese-speaking countries, focusing on their social media platforms. The findings reveal that tú is the predominant PoA in Spanish-speaking institutions, whereas você prevails in Portuguese-speaking institutions on their social media.
