Authors: Rego-Agraso Laura , Ríos-de-Deus María-Paula , Mosquera-González María José , Rodicio-García María-Luisa
Published: May 2023

In the context of the subject of the Degree in Social Education called “Dynamics of communication and collaboration in socio-educational action”, the didactic design corresponding to the experience of analysis of the mainstream music video is presented. This is one of the contents located in the framework of the uses of ICT and networks from the socio-educational point of view. These cultural artefacts produced and distributed by the music industry have millions of views in the various streaming platforms, particularly among young people, and can thus influence the generation of identities and social imaginaries. The methodological design presented here divides the students' work into several consecutive phases using collaborative learning as a central axis. This experience was carried out in the context of the subject, offering an innovative response to the treatment of these contents in the classroom, favouring positive interdependence and promoting interaction as well as indirect familiarization with the precepts of qualitative research. The proposed tasks are approached from a situated point of view, current and linked to a reality close to the students, which awakens their curiosity and motivation. The work also includes oral presentations, the use of technological resources and the development of teamwork skills.

Authors: Rodríguez Rodríguez Carmen , Santiago Gómez Elvira
Published: May 2023

The project Imaginando Reglas is part of the Laboratorio Ciudadano Rompiendo Reglas LAB Menstruacción digna y Ecosaludable promoted by the Gender Equality Group of the Faculty of Education Sciences of the University of A Coruña. The project aims to implement a participatory and collaborative research methodology on menstruation. The objective is to rethink and reconceptualise menstruation, questioning our normalised concept of menstruation, based on a critical view of the methods used to control it. The methodology used consisted in a participatory and collaborative dynamic put into practice in two sessions. Based on the concept of "sociological imagination” (C. Wright Mills), we applied critical thinking by becoming aware of the relationship of the individual with society, with the present and with the past. Based on a serie of questions, the methods used to control menstruation were described, followed by a local, global and historical analysis of the results, which were then shared with the group.

Aim      To study the dynamics of right ventricular function and pulmonary hemodynamics in patients with pulmonary hypertension during mechanical circulatory support of the heart.

Material and methods  A retrospective analysis was performed for 25 implantations of left ventricular assist device performed in the Meshalkin National Medical Research Center from 2006 through 2021. Mechanical assist devices were implanted in 21 men and 4 women (median age, 37.5 [29; 48] years). All patients had severe, NYHA functional class III-IV chronic heart failure refractory to the optimal drug therapy. Invasive measurements showed that mean pulmonary arterial pressure (MPAP) was 50 [44.5; 60] mm Hg, transpulmonary pressure gradient (TPG) was 16 [14; 19] mm Hg, and calculated pulmonary vascular resistance was 5.4 [4.9; 9] Wood units, which is an absolute contraindication (TPG >15 mm Hg or pulmonary vascular resistance >5 Wood units) for heart transplantation (HT).

Results Duration of left ventricular support was from 17 to 948 days. For 12 (48 %) patients, the HT was performed at 180-948 days following the implantation of left ventricular assist device; 3 patients are presently waiting for HT; 10 patients died from various complications, 6 of them died during the hospital stage. Already during the early stage after the implantation of the mechanical assist device, pulmonary hemodynamics significantly improved. Thus, in one week, MPAP decreased from 50 [44.5; 60] mm Hg to 36 [33; 38] mm Hg (р=0.012) whereas pulmonary vascular resistance decreased from 5.4 [4.9; 9] to 2.9 [2.4; 3.6] Wood units (р=0.008). Follow-up showed further improvement of pulmonary hemodynamics; at 1 month, MPAP was 29 [27; 30] mm Hg and by the time of HT, MPAP was 2.0 [24.8; 26.3] mm Hg (р=0.01), i.e., reached a normal level, which made it possible to perform HT. Similar dynamics was observed for other variables that reflected pulmonary hemodynamics.

Conclusion      Mechanical support of the heart is able to alleviate manifestations of pulmonary hypertension in most patients with end-stage heart failure. It is necessary to develop an algorithm for identifying the category of patients with a high risk of progression of right ventricular failure.

Difficulties and Solutions of Intelligent Fitness Assistance Device to Help Students with Weak Physical Fitness
Authors: Liu Yucai
Published: May 2023

Intelligent fitness assistance device is an intelligent (electromechanical or other power) assistance device. According to the
actual situation of students with weak physical fitness, the device gives intelligent help. In order to reduce the difficulty
of fitness and improve the fitness efficiency, this study introduced the relevant theories and technologies in the field of
intelligent electromechanical into students' fitness. We collected and sorted out corresponding theories and technologies
from the field of physical fitness and the field of intelligent electromechanical assistance, sought the integration point
of the two interdisciplinary disciplines, took electromechanical assistance as the main technical support, take students
with weak physical fitness as the service object, and sorted out and innovated intelligent fitness assistance devices mainly
under the guidance and help of experts in physical education and physics. Literature research method, interdisciplinary
research method, simulation method (model method) and other methods were used to collect and sort out corresponding
technologies based on students' fitness needs and innovation. Aiming at the problems of weak physical fitness and
insufficient strength and endurance of students, an intelligent booster device was designed to scientifically improve
the fitness level and effect. In the current sports environment of weak national physique, declining physique of students
of all ages, and extensive restrictions on students' fitness, sports intelligent fitness assistance device is time-saving
and efficient and has strong discipline and technology integration. However, there are integration difficulties between
the two. The sports intelligent fitness assistance device promotes the subjective development of students' fitness in
multi-dimensional and multi-way from the objective level of hardware, in terms of fitness willingness, operation
feasibility Safety controllability and long-term guarantee, which has strong practical significance. The test design
is a push up intelligent electromechanical booster device, which is trial manufactured by using electromechanical theory
and mature ready-made machines (this time, due to limited funds and technical level, the variable frequency lifting motor
that is easy to purchase and test is selected); Computer programming based on single chip microcomputer is used to realize
the integration of computer knowledge and sports knowledge. Generally speaking, the concept of this study is basically
realized, and the device basically runs normally. In the follow-up research and exploration, the scientific and technological
level of research, design and manufacturing will be improved, and more scientific, efficient, and safe devices or equipment
will be provided for students' fitness.
Effects of Active Video Game Interventions on Physical Health and Development Among Healthy Preschool Children
Authors: Zhou Wanjiang , Palos Perez John Jose , Adams Kaitlyn , Gao Zan
Published: May 2023

Early physical activity (PA) interventions during preschool ages are necessary and critical to cultivate healthy movement
behaviors for healthy growth and development. The increasing obesity rate among children is a major public health concern
globally, which is largely due to poor adherence to participating in regular PA. Active video game (AVG) interventions have
been increasingly used in promoting PA. The narrative review synthesized current literature regarding the effect of AVG
interventions on physical health and development indicators among healthy preschoolers. A systematic review was performed
in Academic Search Premier, CINAHL, ERIC, PubMed, SPORT Discus, and Web of Science, following the PRISMA guidelines. A total
of seven experimental studies were included; two were home-based interventions and five were center-based interventions.
Three studies confirmed AVG interventions had a positive effect on the targeted outcomes: fruit and vegetable acceptance,
execution function, and perceived competence. All other studies found partially positive effects on PA levels, motor skill
competence, fundamental movement skills, or cognitive flexibility. The available evidence suggests that AVGs could be a
promising channel to promote PA outcomes that contribute to physical health and development in preschoolers. The results
underline advantages and usages of AVG interventions in preschoolers although evidence provided limited robustness. There
is a paucity of studies that investigated the effect of AVG PA interventions on physical health and development in healthy
preschoolers. Future studies are needed to replicate findings and test feasibility and efficacy of AVG PA interventions.
THE ROLE OF "THINK TANKS" IN THE USA INFORMATION WARFARE SYSTEM
Authors: Romachev Roman V.
Published: May 2023

Aim. To investigate the activities of the U.S.’ “think tanks” in Russia in terms of the intelligence functions they perform to misinform the enemy.

Methodology. By implementing historical sources analysis, content analysis and case studies, the author investigated the U.S.’ think tanks activities and the history of their participation in the informational and psychological warfare against Russia during the SMO in Ukraine in 2022; the intelligence product offered by “think tanks” was also examined in the study.

Results. The study established that private intelligence companies operate under the legend of “think tanks” in USA. They have a significant informational and psychological influence both on a potential enemy (misinform the enemy, induce the enemy to act in a certain manner) and on the domestic and foreign policies of the United States itself.

Research implications. The findings of the study can become the basis for the development of practical recommendations for the Russian authorities on building communication and business relations with the Western think tanks.
The Effect of Corrupt Practices on Electoral Participation, Campaign Activities, and the Performance of the Democratic Transition in Somalia
Authors: Omar Bincof Mohamed
Published: May 2023

The aim of this study is to examine the nexus between electoral corruption and political participation, such as voting and campaign activities, and the performance of the democratic transition in Somalia. Corruption has become endemic in political systems and democratic practices, leading to a global crisis. In particular, fraud, meddling, clannishness, and unsuccessful transitions marred Somalia's electoral past, which contributed to a dysfunctional state. This study used a qualitative method to interview 18 people from different professions. The findings of the study shed light on the pervasive corruption that has plagued recent indirect elections. The study observes that candidates have been threatened, election lists have been altered, votes have been purchased, and results have been manipulated, all of which have discouraged voters. The author finds that since clan representatives and traditional elders are compensated, the decision on who to vote for is also affected. The paper argues that much work remains to protect Somalia's fledgling democracy, achieve political participation, implement anti-corruption and accountability measures, and enact election campaign legislation.

Published: May 2023

Background: It is hypothesized that feeding lactic acid as a feed additive has the potential to alter the pharmacokinetics of many antimicrobial drugs being used for the treatment of infectious disease in general and marbofloxacin in particular; leading to either increased or decreased efficiency. Hence, the present study was planned to explore the effects of lactic acid pre-treatment on the pharmacokinetics of marbofloxacin after oral administration in broiler chickens. Methods: The pharmacokinetics of marbofloxacin was investigated following single dose oral administration (5 mg/kg) in lactic acid pre-treated (8 gm/l each, oral, 10 days) broiler chickens. The plasma concentration of marbofloxacin was determined by ultra-high-performance liquid chromatography to workout pharmacokinetic profile of marbofloxacin using non compartment model. Result: The AUC (area under curve) of marbofloxacin declined from 14.70 ìg·h/mL to 6.16 ìg·h/mL after pre-treatment of lactic acid. Similarly, the average values of maximum plasma concentration (Cmax) of drug decreased from 2.11 ìg/mL to 0.98 ìg/mL and mean body clearance (ClB) increased from 0.47 L/h/kg to 1.03 L/h/kg. The average elimination half-lives (t½â) of marbofloxacin before and after pre-treatment with lactic acid were 4.89 h and 2.81 h, respectively. Furthermore, the investigation revealed alteration of pharmacokinetic parameters evident in lactic acid pre-treated broiler chickens (as compared to non pre-treated birds) requiring adjustment of dosage regimens.

A total of 25 male rats, 3 months of age, 150-200 gram body weight were used. This research consists of five treatments. P0 were normal skin, P1 were used 1% silver sulfadiazine, P2, P3, and P4 were gel combination of binahong leaf and turmeric rhizome extracts with increase concentration of binahong leaf extract i.e. 1.25%, 2.5%, and 5%, while turmeric rhizome extract i. e 2% for each treatment. Treatments have been given topically for 14 days, twice a day, started after burn wound application. At the end of the treatment period, skin excision was carried out, then the histopathological examination was performed. Microscopic observation on the wound healing process on mature collagen density showed that P0 was not a significant difference with P3 and P4, but P0 was significant difference with P1 and P2. The better burn healing process on P3 is allegedly because of the activity of saponin, and tannin, contained in the binahong leaf extract 2.5%, and curcumin in turmeric rhizome extract 2% have been proven to be effective for topical burns therapy.
Numerical Analysis for Estimating Penetration Depth by Ship-dragged Fluke Anchor
Authors: Kang Haneul , Kim Jeonghun , Chun Insik
Published: May 2023

Anchor penetration by ship anchoring is emerging as a major risk factor for submarine cable. A numerical analysis method was established to predict the anchor penetration depth by ship-dragged fluke anchor in relation to setting the optimal burial depth of submarine cable. The soil resisting forces (bearing force, friction force) generated during the anchor penetration process were calculated for each of the fluke, shank and mooring chain of the anchor. The results of the numerical analysis were compared with the existing chart values of Vryhof (2015). It was found that it is desirable to use the force coefficients of strip foundation for the fluke and shank, and the force coefficients of a single vertical pile for mooring chain. The numerical analysis well reproduced the penetration trajectory in which the inclination angle of the lower surface of fluke gradually converged to zero.
Introducing Principles and Standards for Responsible Investment
Authors: Danilov Y.
Published: May 2023

The article provides information on the latest developments in the field of building sustainable finance standards as an integral element of the sustainable development model. The rapid growth of responsible investment naturally created a demand for the formation of principles and standards both for responsible investors themselves and for corporations wishing to attract responsible investments. The development of standards, norms and rules that ensure the effectiveness of responsible investments is carried out in close cooperation with international financial organizations, associations of market participants and regulators. The article presents a general picture of this process, including information about its main participants, their most important decisions and achievements in the field of implementing the concept of sustainable finance. It is divided into 4 blocks. The first block talks about the rules and regulations for responsible investment, including the requirements developed by such investors in relation to themselves. The second block briefly describes the process of standardizing the disclosure of non-financial information and the problems of ensuring its reliability. The standards for disclosure and confirmation of the reliability of information about the adherence of corporations to the principles of sustainable development create the basis for the formation of long-term trust, which is a prerequisite for the functioning of the sustainable development model. The third block briefly describes the styles of responsible investing and the trends in their application. The fourth block is devoted to proposals and projects for central banks to change their monetary policy in order to stimulate responsible investment. The article is aimed at the widest range of readers interested in the problems of responsible investment, focusing on the most important documents in this area developed abroad in recent years.

Published: May 2023

The work reports a facile synthesis of high thermally-stable nanocrystalline anatase TiO2 nanoparticles (NPs) doped with different atomic concentrations (0.5, 1.0, 3.0, and 6.0%) of Gd3+ and Nd3+ ions by a template-free and one-step solvothermal process, using titanium(IV) butoxide as titanium precursor and dimethyl sulfoxide (DMSO) as solvent. The structure and morphology of the Gd3+, Nd3+, and 0.5%Gd3+-0.5%Nd3+/doped TiO2 NPs have been characterized by using various analytical techniques. The Gd3+/ and Nd3+/TiO2 molar ratios were found to have a pronounced impact on the crystalline structure, size, and morphology of TiO2 NPs. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) studies revealed the proper substitution of Ti4+ by Gd3+ and Nd3+ ions in the TiO2 host lattice. The as-prepared Gdx/TiO2, Ndx/TiO2, and Gd1.0/Ndx/TiO2 bimetallic NPs, x = 0.5, 1.0, 3.0, and 6%, have been investigated as electrocatalysts for hydrogen evolution reaction (HER) in 1.0 M KOH solution using a variety of electrochemical techniques. At any doping percentage, the Gd1.0/Ndx/TiO2 bimetallic NPs showed higher HER catalytic performance than their corresponding counterparts i.e. Gdx/TiO2 and Ndx/TiO2. Upon increasing the Nd content from 0.5 to 6.0%, the HER catalytic performance of the Gd1.0/Ndx/TiO2 bimetallic NPs was generally enhanced. Among the studied materials, the bimetallic Gd1.0/Nd6.0/TiO2 NPs emerged as the most promising catalyst with an onset potential of -22 mV vs. RHE, a Tafel slope of 109 mV dec-1, and an exchange current density of 0.72 mA cm-2. Such HER electrochemical kinetic parameters are close to those recorded by the commercial Pt/C (onset potential: -15 mV, Tafel slope: 106 mV dec-1, and exchange current density: 0.80 mA cm-2), and also comparable with those measured by the most active electrocatalysts reported in the literature. The synergistic interaction of Gd and Nd is thought to be the major cause of the bimetallic catalyst's activity.

Published: May 2023

In recent years,"cloud tourism" has developed rapidly and has gained a wide audience, gradually becoming a new operation form of sustainable development in the tourism.However, research on the audience perception, psychological needs, and behavior in this area is still in its infancy. Taking the tourism webcast on the Chinese Weibo platform as an example, this paper constructs a cognitive-emotional model of Chinese tourists' "cloud tourism" and explore the impact mechanism of "cloud tourism" on audience behavioral willingness by drawing on the "cogni-tive-emotional" theory, combining with text analysis and grounded theory. The findings suggest that "cloud tourism" can satisfy the audience's cognitive needs to a certain extent, but the expe-riential nature of tourism is far from sufficient, and it is difficult to realize the essence of tourism. In the future, "cloud tourism" still needs to continuously exert positive effects, becoming a visual presentation of traditional tourism and a novel operation form of sustainable development.

Authors: Chu Shuwen , Liang Yuzhang , Lu Mengdi , Yuan Huizhen , Han Yi , Masson Jean-Francois , Peng Wei
Published: May 2023

Metal plasmonic nanostructures have promising applications in biosensing due to their ability to facilitate light-matter interaction. However, the damping of the metal leads to a wide full width at half maximum (FWHM) spectrum and results which restricts its sensing capabilities. In this research, we present a novel non-full-metal nanostructure, namely indium-tin oxide (ITO)-Au nanodisk arrays consisting of top ITO nanodisk arrays and a bottom gold layer, and compare the coupling mode with the full-metal nanodisk arrays. The FWHM of proposed ITO-Au nanodisk array reduces to one fifth of that all metal nanodisk arrays, which is generated mode-coupling by surface plasmon modes at metal interfaces with magnetic resonance mode. Furthermore, the thickness variation of nanodisks has no impact on the sensing performance of this ITO-based nanostructure, ensuring excellent tolerance during preparation. We fabricated both structures by using template transfer and vacuum deposition techniques and calibrated their sensing performances by detect Immunoglobulin G (IgG) protein molecules. Both theoretical and experimental results demonstrate that ITO-Au nanodisk arrays provide an effective solution for biosensing applications.
A Brief Review on Micro-particle Slurry Rheology in Grinding and Flotation for Enhancing Fine Mineral Processing Efficiency
Authors: Zeng Guangsheng , Zhu Yangge , Chen Wei
Published: May 2023

These years have witnessed growing research on applying rheology in grinding and flotation treatment of finely disseminated ores. The slurry rheology has long been identified as the comprehensive effect of inter-particle interactions, including their aggregation (coagulation and flocculation) and dispersion states in slurry, which are more impactive under the fine-particle effect. In this regard, rheology has the potential to play a significant role in interpreting the flowing and deforming phenomenon of inter-particle aggregates, particle-bubble aggregates, and flotation froth. Though much attention has been paid to the rheological effect in industrial suspension, this has not been the case for mineral grinding and flotation for fine particles. The influential mechanism of rheology on the sub-processes of mineral processing has not been systemically concluded and revealed thoroughly, without which the underpinning mechanism for enhancing the processing efficiency has been difficult to discover. This paper reviews the current application and importance of rheology in the fine mineral processing, and the potential research direction in the field is proposed.

Published: May 2023

Video behavior recognition often needs to focus on object motion processes. In this work, a self-organizing computational system oriented to behavioral clustering recognition is proposed, which achieves the extraction of motion change patterns by binary encoding and completes motion pattern summarization using a similarity comparison algorithm. And in the face of unknown behavioral video data, a self-organizing structure with layer-by-layer accuracy progression is used to achieve motion law summarization by using a multi-layer agent design approach. Finally, the real-time feasibility is verified in the prototype system using real scenes to provide a new feasible solution for unsupervised behavior recognition and space-time scenes.
Spacetime as a Complex Network and the Cosmological Constant Problem
Authors: Nesterov Alexander
Published: May 2023

We propose a promising model of discrete spacetime based on nonassociative geometry and complex networks. Our approach treats space as a simplicial 3-complex (or complex network), built from "atoms" of spacetime and entangled states forming n-dimensional simplices (n=1,2,3). At large scales, a highly connected network is a coarse, discrete representation of a smooth spacetime. We show that for high temperatures, the network describes disconnected discrete space. At the Planck temperature, the system experiences the phase transition, and for low temperatures, the space becomes a triangulated discrete space. We show that the cosmological constant depends on the universe’s topology. The "foamy" structure, analogous to Wheeler’s "spacetime foam," significantly contributes to the effective cosmological constant, which is determined by the Euler characteristic of the universe.
NUVO Model for the Grand Unified Theory Initial Formalization Part I: Cosmic Scale
Authors: Austin Rickey
Published: May 2023

n this article a first attempt at formalizing a new approach to the grand unified theory is introduced. This theory named NUVO is based primarily on considering two aspects of inertia. The first aspect is how a mass couples to space, introducing definitions to distinguish massive particles from massless particles. The second aspect is space’s availability to couple to massive particles. In essence these are the two contributions of inertia; mass and space. Postulates, clarifications, and a mathematical structure are introduced. Part 1 covers the physics of the very large (cos- mic), laying ground work for part two which applies the structure to the very small (quantum). The cosmic application of the theory will show a strong correlation to empirical data and correspondence to General Rela- tivity, including; time dilation, length contraction, and orbital advances. Departing from the canonical findings of General Relativity by predicting a quantization of physical units under the effect of acceleration and or gravity.

Published: May 2023

One of Indonesia's development goals in 2020-2024 is to form quality and competitive human resources. One of the efforts to achieve this goal is to improve the quality of maternal and child health. However, the issue of Maternal and Child Health (MCH) is still a challenge for the Indonesian health system. This study aims to determine the modeling and to obtain provincial groupings based on the degree of maternal and child health in Indonesia. The method used is Structural Equation Modeling Partial Least Square-Prediction Oriented Segmentation (SEM PLS-POS). The results of the PLS SEM analysis showed that the environmental variables and health services had a significant effect on the health status of mothers and children with an R2 value of 48.8%. The grouping of provinces based on the degree of maternal and child health in Indonesia using PLS-POS produces 3 segment classes. Segment 1 consists of 11 provinces, segment 2 consists of 13 provinces and segment 3 consists of 10 provinces with a large influence between different latent variables.
Hopf Bifurcation in a Modified Leslie-Gower Two Preys One Predator Model and Holling Type II Functional Response with Harvesting and Time-Delay
Authors: Waldani Gesti Essa , Chalimatusadiah Chalimatusadiah
Published: May 2023

In this paper, a modified Leslie-Gower two preys one predator model and Holling type II functional response with harvesting and time-delay were discussed. Model analysis is carried out by determining fixed points, then analyzing the stability of the fixed points and discussing the existence of the Hopf bifurcation. In some conditions that occur in nature indicate the occurrence of hunting of prey and predator species by humans. Therefore, this model is modified by adding the assumption that prey and predators are being harvested. Another modification given to the model is the use of time delays.The delay time term is for taking into account the case that the members of the predator species need time from birth to predation for being active predators. The first case is a model without time delay, it is obtained that 3 fixed points are unstable and 7 fixed points are stable. One of them is the interior fixed point tested with the Routh-Hurwitz criteria. The second case is a model with a delay time, the critical delay value is obained. Hopf bifurcation occurs when the delay time value is equal to the critical delay value and also fulfills the transversality condition. Observations on the model simulation are carried out by varying the value of the delay time. When the Hopf bifurcation occurs, the graph on the solution plane shows a constant oscillatory movement. If the value of the delay time given is less than the critical value of the delay, the controlled system solution goes to a balanced state. Then when the delay time value is greater than the critical delay value, the system solution continues to fluctuate causing an unstable system condition.

The purpose of this study is to find out how the critical discourse analysis of Kompas.com and Republika.co.id in reporting on the proposed postponement of the election which was rolled out by Muhaimin Iskandar as a political ijtihad. Using a qualitative approach with the critical discourse analysis method of the Van Dijk Model, several theories in research place Image Theory, Ijtihad Theory as supporting theories for the main theory. The results of the study show how each media in March equally objectively discussed themes related to the proposed postponement of the elections initiated by Muhaimin Iskandar and several political party leaders. This conclusion is reinforced by the macro structure, super structure, and macro structure which mutually reinforce the theme. The situation was different when the phenomenon of rejection began to emerge towards the idea of postponing the elections in April 2022. Even though the discourse that was presented seemed to be the same, if observed in detail there were differences that emerged between the two media. Kompas.com at this moment still tends to be objective in discussing Muhaimin's mature attitude, which seems not to insist on continuing his idea. Republika.co.id presents different discourse concepts through macro-structure, super-structure and micro-structure which tend to be unfavorable to Muhaimin's position, one of which is because he makes joke-like quotes as headlines. In the perspective of ijtihad in the field of self-image politics, what Muhaimin Iskandar has done through the proposed postponement of the 2024 elections can be called the seriousness of the parties concerned to build their own image.
