The Changes of Histone Methylation Induced by Adolescent Social Stress Regulate the Resting-State Activity in mPFC
Authors: Wang Jiesi , Zhang Wei , Xu Hang , Ellenbroek Bart , Dai Jiajie , Wang Li , Yan Chaogan , Wang Weiwen
Published: October 2023

Early-life stress can lead to sustained alterations in regional resting-state brain functions, but the underlying molecular mechanism remains unclear. Stress can also induce sustained changes in epigenetic modifications across brain regions, which are not limited to a few genes; rather, they often tend to produce global levels of change. The functional implication of these changes also remains to be elucidated. We hypothesize that global epigenetic changes may partly modulate the resting-state functions of brain regions to influence behavior. To test this hypothesis, we used an adolescent social stress (ASS) model in mice and examined the relationship between epigenetic modifications and regional resting-state brain activity using resting-state functional magnetic resonance imaging (rs-fMRI). The results showed that, compared to the control mice, the stressed mice showed increased anxiety and social avoidance behaviors and greater levels of dimethylation of histone H3 at lysine 9 (H3K9me2) in the medial prefrontal cortex (mPFC). In addition, the resting-state activity represented by the amplitude of low-frequency fluctuation (ALFF) was significantly lower in the mPFC of stressed mice. To verify the relationship of H3K9me2 and ALFF, the specific inhibition of H3Kme2 was performed by using the drug UNC0642, which reversed the anxiety behavior induced by ASS and significantly increase the ALFF value of mPFC in both normal and ASS animals. Our study is the first to report an association between histone modifications and rs-fMRI findings, providing a new perspective for understanding of the significance of regional brain epigenetic changes and a possible molecular explanation for rs-fMRI findings.
TOTAL FLOAT MANAGEMENT TECHNIQUE UNDER THE FLOAT AND RESOURCE LOADING
Authors: Vo Huy Minh
Published: October 2023

Schedule delays in construction projects are a common occurrence and have a significant impact on the overall project duration. Plentiful delay analysis techniques have been proposed and utilized to resolve these issues.The total float management method is widely accepted and considered the most fundamental approach as it effectively resolves four major delay issues and measures float consumption. However, current delay analysis techniques have often overlooked the allocation of float and resources, which can remarkably affect the determination of delay responsibilities for involved parties. This study aims to enhance the total float management approach by intensively incorporating float and resource loading considerations before delayanalysis implementation. The research methodology includes an extensive literature review, identification of crucial issues related to schedule delays arising from the lack of resource and total float allocation, and the application of enhanced total float management under float and resource loading through a case study for test validation. The research findings provide transparent insights into delay liability considering both time delays and float consumption and emphasize the importance of float and resource allocation in the early stages of construction projects for a consensus before analyzing and assigning delay responsibilities. Future studies could focus on legalizing the procedural considerations of float ownership and resource allocation in contractagreements.

A research and development study was conducted from September 2020 to April 2023 involving 9 hospitals, 24 district health centers and 319 commune health stations. The main objective of the study was to establish,refine, and update a system for controlling directly transmitted diseases in Ho Chi Minh City, as well as assess its practical implementation. Before the system update, the study identified limitations in disease surveillance, particularly in monitoring cases that were not examined or treated at hospitals. The existing reportingmechanisms also resulted in incomplete disease data, with subpar data quality due to delays and inadequate processing of reported cases. Considering the prevailing circumstances, management requirements and usage needs, the system underwent enhancements and integrated GIS capabilities. This allowed healthcare personnel to swiftly and accurately identify disease cases, determine contacts, establish epidemiological zones, tracetransmission chains, and monitor the implementation of control measures. The improved control system has been successfully implemented, ensuring effective management of community-based hand, foot, and mouth disease. Additionally, the system demonstrates the potential for broader applicability in managing other directly transmitted  diseases.

Published: October 2023

Currently, the utilization of cocoa pod has not been maximized, resulting in waste and foul odors that disturb the environment. However, cocoa pod  contain a relatively high amount of cellulose compounds that serve as an energy source or nutrition for bacteria to carry out metabolic activities, thus holding the potential to be used as a substrate in microbial fuel cells (MFC). Based on this, the aim of this research is to investigate the bioelectricity generated by a MFC using cocoa pod husk as a substrate, including voltage, current, and power density, in order to determine the potential of cocoa pod husk waste as an electrical energy source. In this study, a double chamber MFC consists of an anode chamber with copper electrodes and a cathode chamber with zinc electrodes, separated by a salt bridge. The bacteria used were Saccharomyces cerevisiae, and the substrate was made from cocoa pod husk waste. Bioelectricity testing involved measuring the voltage, current, and power density produced by the MFC over several minutes. The measurement results for maximum voltage, maximum current generated, and maximum electrical power (at 6 days) from the reactor were as follows: 36.0 mV, 0.19 mA, and 456 mW/m2, respectively.
For a Better Disaster Management in Türkiye's 100th Anniversary: District Disaster Management
Authors: KOVANCI Ezgi
Published: October 2023

On the planet, there are various natural hazards, and in the coming years, their frequencies and intensities are likely to vary. These disasters can be diversified into subcategories. Regardless of the way disasters occur, the consequences they create can lead to catastrophic outcomes for both humanity and the environment. It is evident that inequalities among countries result in some nations bearing a more severe burden of the consequences, despite being less responsible for environmental degradation. Due to inadequate infrastructure and financial resources, these countries endure the repercussions more harshly and become more vulnerable. Despite differences in the levels of fragility and development among countries, it is possible to minimize the risks of disasters turning into catastrophes through organized disaster management. In the study, the distinction between the terms hazard, disaster, and catastrophe is clarified in order to eliminate conceptual confusion. Additionally, the development indices of countries and their vulnerability to disasters are evaluated. In the second section, the essential elements of effective disaster management are outlined in subcategories. The third and final section of the study elaborates with examples on why district disaster management plans should be an effective model in disaster management.
“Soft skills” in foreign studies: Sociological, marketing and educational approaches
Authors: Getmanskaya E. V. , Chertov V. F.
Published: October 2023

The article presents a wide range of foreign studies on the influence of soft skills on the success of business environment in the context of the dynamics of “soft skills” development. The subject of thematic analysis includes business research, sociological measurement data, information from career centers, a management perspective, academic research, and educational technologies. The heterogeneity of the fields of analysis is due to the authors’ twofold aim: to present the understanding of soft skills in the academic environment and to characterize the models of their formation at different stages of education and working life. In this regard, professional groups of students and workers (programmers, construction workers, MBA students) were analyzed, and significant differences in the amounts and sequences of their soft skills acquisition were revealed. Scientific works that propose variants of soft skills taxonomy are studied; attention is paid to objective difficulties in formalizing personalized competences. The conclusion is formulated that today the efforts of foreign research thought regarding the systematization of soft skills are fixed on the enumerative (non-hierarchical) principle, as evidenced by numerous lists of soft skills in Western and Asian interdisciplinary studies, while the problem of soft skills formation requires their clear ranking. In general, the article can be addressed both to researchers studying “soft skills” and their indicators within a particular professional group, and to scientists analyzing the general understanding of soft skills that has been consolidated in foreign scientific literature over the last two decades.
On the analysis of sociodynamics of student youth competences in the sphere of Internet technologies and safety of network behavior

Published: October 2023

The article analyzes the sociodynamics of student youth competences, in particular future lawyers, in the sphere of information technologies and security of network behavior in the conditions of activation of destructive network influences during the special military operation of Russia on the territory of Ukraine. The relevant competencies of students were analyzed in the framework of systematic, purposeful mastering of them according to the results of the entrance and final questionnaire in the form of self-analysis. In the process of the research the following tasks were solved: (1) study of the sociodynamics of network behavior of young users, their knowledge, competencies, attitudes, specific actions and deeds that affect the physical and psychological state in the conditions of interaction in the virtual environment and the use of digital technologies; (2) analyzing the knowledge about the risks of destructive effects of using various Internet resources and content, studying their readiness to counteract negative network influence in modern conditions; (3) analyzing the correlation of the obtained data with the analytics published on the Internet in 2020–2022 based on the results of sociological surveys on similar topics.

As the surveys have shown, in order to form safe online behavior of young people on the Internet, minimize the risks of destructive network influence, and ensure information security, it is important to initially and systematically instill the skills of competent online behavior in children, adolescents and young users at all stages of their development and education. It is necessary to teach them to correctly define the boundaries of reliability and misinformation, to ensure the mastery of knowledge about the basics of information security, to form and consolidate skills and competencies to apply the acquired knowledge, including critical thinking, and to counteract destructive network influences. These tasks are especially relevant in the current socio-political environment of special military operation and intensification of information warfare.

On the issue of circumstances, aggravating punishment in the commission of crime, under Article 2434 of the Criminal Code of the Russian Federation
Authors: Seliverstov N. O.
Published: October 2023

The article studies problematic theoretical issues of application of the criminal law in case of presence of circumstances aggravating punishment in case of destruction or damage of military burial places, as well as monuments, steles, obelisks, other memorial structures or objects perpetuating the memory of those who died in defense of the Fatherland or its interests or dedicated to the days of military glory of Russia, according to article 2434 of the Criminal Code of the Russian Federation (CC RF). In particular, the most common circumstances aggravating punishment in committing an act under article 2434 of the Criminal Code of the Russian Federation are investigated, namely: in cases of recidivism of crimes, occurrence of grave consequences, committing a crime during mobilization. The author applied the methods of statistical, systemic and comparative legal analysis, formal logic. It is argued that the recognition of recidivism of a crime does not affect the social danger of a deed, but this circumstance should be taken into account in penalization for the appointment of fair punishment based on the personality of the offender. The author’s classification of grave consequences to be taken into account in the case of committing an offense under Art. 2434 of the Criminal Code of the Russian Federation is proposed. A number of aspects of such a circumstance aggravating punishment as committing a crime during mobilization, especially in relation to negligent crimes, are criticized. The author concludes that it is justified to take into account the commission of a crime during mobilization in relation to article 2434 of the Criminal Code of the RF. This will have a positive impact on the practice of imposing criminal punishment for a crime against the historical memory of those who died in defense of the Fatherland, especially since the purpose of imposing a just punishment — including the prevention of committing socially dangerous acts.

Published: October 2023

Brushing your teeth is one way to clean your teeth and take preventive measures in improving dental and oral hygiene. The horizontal technique is a technique that is widely used when brushing teeth. The roll technique is often recommended because it is simple and efficient, while the fone's technique is a proven technique suitable for children because it is easy to do. The purpose of the study was to analyze the hygiene index of brushing teeth with horizontal method, roll and fone's method in children aged 9-12 years. This type of research is an quasi-experimental research with pre-test and post-test designs. There search was carried out by treating respondents and checking the n hygiene index before and after brushing teeth with the horizontal method and the fone's method. The study sample amounted to 45 people with three treatments. The data were analyzed by t-test. The results of the study with paired t-test ? value (0.00<0.05) mean that there is a significant difference between before and after brushing teeth with horizontal, roll and fone's techniques. The average surface of these cleaned teeth is no more than 75% of the tooth surface. The horizontal method averages 51.55%, roll 72.57% and fone's 70.05%. Judging from the increase in hygiene index score, the highest horizontal method increased hygiene index by 34.5%. There is no difference in hygiene index after brushing teeth with horizontal roll and fone's methods. It is recommended to respondents to brush their teeth at least twice in the morning before eating and at night before going to bed with brushing techniques that have been taught, especially fone's. For further researchers, it is recommended to examine the hygiene index with other brushing methods in order to see more effective methods in cleaning all tooth surfaces.

Authors: Cantelli-Forti Alessandro , Colajanni Michele , Russo Silvio
Published: October 2023

The risk of data exfiltration remains a concern, even when the connectivity of the victim system is limited or the domain is physically isolated. This paper delves into the unique challenges associated with data exfiltration in surface and submarine naval scenarios in the absence of persistent data connections. It explores contexts where attacks through the supply chain can pose a serious risk even if the compromised hardware or software is not connected to any network or even (apparently) switched off. The attacks exploiting vulnerabilities in some components of the supply chain can serve as a conduit for data exfiltration. This study aims to enhance the overall security posture of maritime systems by identifying possible exposures and mitigating the risk of data exfiltration and covered channel attacks.

Published: October 2023

This paper presents a comprehensive approach to designing and optimizing a Hierarchical Rule-Base Reduction (HRBR) based Adaptive-Network-Based Fuzzy Inference System (ANFIS) for symmetric linguistic variables. Specifically, the linguistic joint membership functions that underlie the ANFIS are defined, focusing on symmetrical inputs/outputs and jointly optimized trapezoid membership functions to reduce the number of training parameters. Further optimizations for the ANFIS were derived based on design assumptions, including training the membership functions on closed or single-sided domains. The optimal output membership weights based on mean square error optimization were also symbolically obtained. The online training of the ANFIS's input/output membership functions was performed using the DDPG (Deep Deterministic Policy Gradient) algorithm. A simulated skid-steered vehicle was used to validate the approach and performed waypoint-to-waypoint path following. Experimental results using the Clearpath Jackal demonstrated that the ANFIS model converged quickly, typically within 6 to 10 episodes of training, from an initial MAE and RMSE of 0.88 and 1.02 meters, respectively, to a final MAE and RMSE of 0.087 and 0.10 meters. The results highlight the effectiveness of the ANFIS approach for vehicular robotics applications and suggest promising avenues for future research and development.

Micro-electro mechanical systems (MEMS) accelerometer has been implemented in various applications across industries. To expand its application to textiles, here we propose a facile fabrication and packaging method for fiber-shaped flexible MEMS thermal accelerometer. The sensing structure was fabricated through a standard microfabrication process on a thin polyimide film substrate. The film was then cut into stick shape and packaged inside a flexible resin tube through a facile insertion process. A sensitivity improvement strategy by mitigating the thermal mass around the sensing structure was also introduced. Gravitational acceleration measurement using the proposed sensors was demonstrated using an inclination stage. Finally, measurement of human hand movement using the proposed sensors was demonstrated.

New Results of Target Circumnavigation Problem with UAV Using Bearing Measurements
Authors: Wang Dongzhen
Published: October 2023

Target tracking using bearing-only measurement with UAV is extensively studied recently years because of its potential value in engineering applications. This brief revisits the problem about slowly moving target tracking using the target circumnavigation scheme. Instead of developing improved algorithm, we mainly present some new results for the typical circumnavigation algorithm in the literature. From a different perspective, the overall convergence analysis is conducted for the typical algorithm under the same conditions assumed in existing work, and it is found that the conclusion made in prior work is not accurate because of the implicity assumption. In this brief, we present a more accurate convergence analysis for the typical target circumnavigation algorithm, simultaneously giving the sufficient conditions for convergence or divergence. Simulation examples validates our results.
Unlocking the Power of Reconfigurable Intelligent Surfaces: From Wireless Communication to Energy Efficiency and Beyond
Authors: Pereira de Figueiredo Felipe Augusto
Published: October 2023

Reconfigurable Intelligent Surfaces (RIS) are a class of metamaterials that have gained significant attention in recent years due to their potential to revolutionize wireless communication, sensing, and imaging technologies. RISs consist of a planar array of closely spaced, subwavelength-sized elements that can manipulate electromagnetic waves in a controllable manner. By reconfiguring the geometry, material properties, or phase of individual elements on the RIS, the surface can be customized to meet specific application requirements. 

RISs can potentially improve wireless communication by creating virtual channels, reducing interference, and improving overall quality. They can also enhance the efficiency of energy harvesting systems and improve sensing and imaging technologies by manipulating the propagation and scattering of electromagnetic waves. Additionally, RIS could be used to increase privacy and security by selectively blocking or allowing certain frequencies of electromagnetic waves. 

In this article, we provide a brief history of the development of RIS and discuss the design and fabrication of RIS structures. We also explore the potential applications and benefits of RIS technology, including improved wireless communication, enhanced energy efficiency, advanced sensing and imaging, and increased privacy and security. Finally, we highlight some of the current research challenges and future directions for RIS technology. Overall, RISs hold great promise for advancing a wide range of technologies and applications, and we expect to see many exciting developments in this area in the future.

Published: October 2023

We present a new anisotropic driving force model to compute the anisotropy of the mobility and impact ionization rate in TCAD simulations of SiC devices. We derive the model from the relationship between the mobility, driving force, and carrier heating, where the obtained driving force along the c-axis and that perpendicular to the c-axis depend on the gradient of the quasi-Fermi potential and the mobility anisotropy factor (the mobility ratio along the perpendicular direction to that along the c-axis). Since mobility also depends on the driving force, we solve for the mobility anisotropy factor to determine the anisotropic mobility and driving force together. We also propose a new interpolation scheme to consider the anisotropy of the impact ionization rate using the derived anisotropic driving force. We compare the present model with the existing models in the commercial simulator and demonstrate its applicability to the simulation of a 4H-SiC vertical power MOSFET device. 
A Stable Quadrupedal Jumping Control based on SLIP Dynamics Realization with High Reduction Ratio Actuator
Authors: Hong Jeongwoo , Bae Sangjin , Hong JinSong , Yeo Changmin , Oh Sehoon
Published: October 2023

Recent quadruped robots achieve high performance motion control relying on optimization and reinforcement learning. However, there’s ongoing research to achieve high performance motion control through dynamic motion implementation based on simple and dominant principles. In this paper, a control approach is proposed that employs admittance control in the rotating workspace to project the SLIP dynamics onto articulated legs, which describes the dynamic behavior of the compliant leg. Furthermore, a comprehensive control framework is presented that allows the motion control of the quadruped robot exploiting the SLIP dynamics by establishing a Jacobian that relates the motions of trunk and SLIP-realized legs. Notably, the robotic leg used in this work features high reduction ratio gears, typically unsuitable for the legged robots due to low backdrivability and significant joint nonlinearity. Through the vertical jumping motion, the effectiveness of the proposed method is validated, which enables the quadruped robot motion control with SLIP-realized legs, even with high gear ratio actuators.

Published: October 2023

In the last years, location-aware services and network management have driven the demand for user location estimation in mobile networks. Nevertheless, the location obtained from user terminals is not usually accessible to mobile operators. In addition, available cell Key Performance Indicators (KPI) vary highly from network to network, and only a few of them are always enabled widely. Currently prevalent Machine Learning (ML) based solutions have achieved high precisions, but they are bounded to a trained scenario, restricting their application to new areas. We propose a method for creating scenario-agnostic prediction models which solves the above problems by applying feature engineering, over a small set of easily obtainable KPIs, applicable for any ML method. Finally, the performance of the proposed method is demonstrated using a real network dataset.

Досліджено характеристики та параметри фотоелектричних модулів (ФМ), які отримані шляхом швидкого сканування вольт-амперних характеристик (ВАХ) за допомогою автоматизованої вимірювальної системи на мікрокомп’ютерній платформі Rasberry Pi. Розроблено теоретичну модель та алгоритм обробки даних для аналізу змінення параметрів ФМ з напругою й отримання їх взаємозалежностей. Чисельне визначення цих параметрів дає змогу охарактеризувати електричні втрати й процеси рекомбінації в фотоелементах при різних зовнішніх умовах. Показано, що в окремих областях напруги поблизу точки максимальної потужності коефіцієнт неідеальності pn-переходу А може набувати великих значень (до 4-5), що характерно для ФМ, виготовлених за сучасними технологіями. Проаналізовано змінення послідовного опору Rs і фактора A поблизу напруги холостого ходу залежно від рівня сонячної радіації.

The model of coaching for prisoners in Correctional Institutions is inseparable from a dynamic, which aims to provide more provisions for prisoners in facing life after completing their sentence (free). The research method used is normative juridical. The results of this study conclude that the functionalization of the prisoner development system in the Penitentiary in realizing the purpose of punishment is as an implementing agency for the guidance of prisoners based on protection through its functions, namely providing education, rehabilitation and also reintegration. The factors that hinder the implementation of the purpose of sentencing in Correctional Institutions are influenced by the factor of integration between the criminal justice sub-systems, the factors of the law that still seem "opposite" to the spirit of development, the factor of the perpetrators of the crime, the factor of human resources, in this case Prison officers, infrastructure factors and legal culture factors.

Authors: Sousa Livia Lopes de , Souto Fernanda Carneiro de Bastos
Published: October 2023

O aumento da população idosa no Brasil e seus desafios de saúde bucal são temas cruciais que requerem atenção urgente. Com base em dados demográficos e de saúde, é evidente que os idosos enfrentam barreiras significativas no acesso aos serviços odontológicos adequados. O objetivo deste trabalho foi identificar as principais barreiras para promoção da saúde bucal nos idosos no Brasil. Tratou-se de uma revisão narrativa de literatura, que utilizou os descritores de pesquisa: “Idosos” e “Saúde Bucal” e “Promoção saúde” junto com os operadores booleanos “AND” e “NOT” seus correspondentes na língua portuguesa e inglesa. Inicialmente, os descritores foram utilizados através do PubMed Advanced Search Builder - pelos MeSH`s da base de dados PubMed. Posteriormente, foi realizada a busca na livraria eletrônica Scielo. Foram encontrados 93 artigos nas duas bases de dados com a possibilidade de serem selecionados. Após realizar a filtragem pelo título e resumo, foram selecionados 77 artigos, ao passo que somente 42 atenderam aos critérios de inclusão. Concluiu-se que, para superar as barreiras e promover efetivamente a saúde bucal dos idosos, é essencial adotar medidas abrangentes que incluem a reformulação das políticas e do sistema de saúde pública, com foco na disponibilidade de serviços odontológicos de qualidade para essa faixa etária. Além disso, é fundamental sensibilizar a população idosa sobre a importância dos cuidados com a saúde bucal, destacando como isso afeta diretamente sua qualidade de vida.

Published: October 2023

Introdução: Muitos indivíduos encontram-se insatisfeitos com a cor atual dos seus dentes e neste contexto destaca-se a busca por dentes brancos.  Porém, devido ao custo elevado do tratamento de clareamento dental em consultórios, alguns produtos chamados “over the counter” (produtos de venda livre em farmácias ou supermercados) surgiram no mercado prometendo clarear os dentes sem muito esforço, como pastas dentais clareadoras e os enxaguatórios bucais clareadores, possindo diversos princípios ativos, que utilizados em associação com a escova dental prometem clarear as estruturas dentárias. Mas, será se há realmente nesses cremes dentais substâncias químicas clareadoras? Objetivo: Analisar os cremes dentais clareadores disponíveis no mercado, com o intuito de avaliar a sua composição química e verificar a existência de substâncias clareadoras em sua formulação, a fim de avaliar se esses produtos são efetivos em clarear os dentes. Método: Estudo observacional, a escolha dos locais de coleta foi feita por conveniência e a amostra do estudo foi selecionada de forma randomizada. Foi elaborado um quadro para a identificação de cada produto, de acordo com o rótulo do mesmo, contendo: data da coleta, número da amostra, classificação do dentifrício, marca e os clareadores listados. A análise dos dados foi realizada de acordo com o método de análise temática de Braun e Clarke. Resultados: Foram coletados 21 cremes dentais, sendo 8 marcas comerciais. Dentre os 21 cremes dentais analisados, 90,4% dos cremes dentais analisados possuíam apenas produtos substâncias abrasivas em sua composição, e aqueles que apresentaram substância clareadora (9,5%), a substância encontrada foi o peróxido de hidrogênio 1%. Os principais abrasivos encontrados nas amostras foram a sílica hidratada (90%), seguida do dióxido de titânio e bicarbonato de sódio, ambos com 38% e Mica (23,8%). Conclusão: A maioria dos cremes dentais analisados, que alegam ter efeito clareador, não contêm substâncias clareadoras efetivas em sua composição. Em vez disso, o efeito clareador é obtido por meio do uso de agentes abrasivos.

Este artigo tem como objetivo evidenciar o grau de conhecimento dos funcionários do MT - Hemocentro, sobre o manuseio dos resíduos sólidos gerados pela instituição. Trata-se de uma estudo descritivo conduzido no Hemocentro de Mato Grosso, cuja amostra foram os 61 funcionários que estavam em atividade e aceitaram participar da pesquisa respondendo ao instrumento de pesquisa, sendo 84% do sexo feminino e 16% do sexo masculino, distribuídos em setor de atuação abrangem o Laboratório com 34% da amostra; 30% da amostra para o setor de Doação; 23% da amostra para o setor do Ambulatório e 13% da amostra para o setor de Administração da instituição. Conclui que o Hemocentro do MT produziu em média 6 toneladas de resíduos classificados A e E no período de janeiro a abril de 2009. Foram identificadas oportunidades de melhorias dentro do PGRSS entre elas destacamos: necessidade de treinamento mais intensivo, em especial no tema “relevância da segregação”, a implementação da visão do todo no processo de gerenciamento de RSS, uma vez que uma parte importante da equipe desconhece o terno “disposição final” e veem pouco o seu papel na corresponsabilidade da gestão ambiental.
