Prior to the intensified civil and armed conflicts in Ethiopia, remarkable progress was made in the health sector, which has persuaded the  Ministry of Health to give special focus on building a responsive and resilient health system in the second five-year health sector  transformation plan (HSTP II 2021-2025). However, the years-long civil and armed conflicts have been fueling the COVID-19 crisis and  have caused multi-sectoral infrastructure damage, human life loss, and economic crisis. In 2021 alone, the conflict causes more than five  million internal displacements of persons (IDP) and thousands civilian deaths. Review of reported government data has shown that 3,508  health posts, 750 health centers, and 76 hospitals were partially or completely damaged in four regions. Looting of medical equipment and facilities for amenities was devastating. More than 19 million people were affected by the armed and civil conflicts between 2020 and  2021. Unless peace is ensured across the nation the sooner possible, it is foreseen that the devastation may further worsen, and recovery  may be a far-fetched possibility. Therefore, in addition to restoration of the disrupted health services, it is the right time for the Ministry  of Health to incorporate the humanitariandevelopment nexus as a joint strategy with the Disaster Prevention and Preparedness  Commission (DPPC) to ensure a resilient health system for similar multifaceted conflict-related health crisis, disasters, and infectious  outbreaks.
Mostafa Maged sling technique to treat prolapsed uterus in an easy way (New Technique)
Authors: Ali Mostafa Maged
Published: September 2023

Background: In the female population, pelvic organ prolapse is a common problem that lowers people's quality of life in terms of their  health. Depending on the severity of the prolapse and the symptoms, there are many treatment options. Simple observation, vaginal  pessaries, or surgical management are all possible treatments. Reconstructive pelvic surgery with or without mesh augmentation and  obliterative surgery are two surgical treatments that are available. Due to the contentious concerns surrounding the use of mesh and the  rising demand for uterine preservation, surgical practices are currently shifting.

Methods: Just two cases are included in this study due to  the rarity of this condition. In this study, I introduce a new technique to the literature (Mostafa Maged sling technique) which will be challenging. This technique depends on round ligaments and ovarian ligament to hitch up the whole uterus.

Results: There were no  difficulties following the procedure. None of the patients required blood transfusions, and there were no signs of dehiscence or incision  infection. Non-steroidal antiinflammatory medications were administered to both patients as analgesia. On the first postoperative day,  the foley catheters were removed from both patients.

Conclusion: A simple and new manueuver is applied in the literature to treat the  uterine prolapse. It is easy to learn and easy to perform. We need further studies to compare different techniques including Mostafa  Maged sling operation to manage uterine prolapse.

Published: September 2023

Background: Ethiopia has implemented a community-based health insurance (CBHI) program to provide coverage to 80% of the  population and shield underprivileged individuals from the detrimental effects of exorbitant medical expenses. However, there is a  paucity of data regarding its utilization and pertinent concerns. This study aimed to evaluate the utilization of CBHI and its associated  factors among informal workers in Berek District.

Methods: This community-based cross-sectional study was conducted between June 15  and July 15, 2022. The sample population comprised 538 households selected using a multistage sampling approach. Data analysis was done using SPSS Version 26. Variables with P-values of less than 0.25 during the bivariate analysis were selected for multivariate analysis  using binary logistic regression. The statistical significance threshold was set at a p-value of 0.05.

Results: The utilization of Community- Based Health Insurance (CBHI) was 49.8%. Age between 30 and 39 years, monthly earnings of less than 1500 Ethiopian Birr, presence of  chronic illness, membership in social organization, and possessing adequate knowledge were found to have a statistically significant association with the use of CBHI.

Conclusion: The utilization of CBHI was low within the confines of this district. Age, income, social group  membership, and chronic illnesses were significantly associated with CBHI utilization.

Ticks are a significant threat to livestock production, and the synthetic acarcides used to control them have had negative effects on the environment, non-target organisms and the animals being treated. As a solution to this problem, it is necessary to explore alternatives that are safer for humans, animals, and the environment. The use of medicinal plants offers a promising solution. In this study, the acaricidal efficacy of Momordica charantia, a medicinal plant, was evaluated using the adult immersion test (AIT). The aqueous extract and essential oil (EO) of M. charantia leaves were evaluated. A positive control (2% cypermethrin) and negative control (distilled water) were used. Different concentrations (2.5, 5, 10, and 20%) of both aqueous and EO of plant were tested with 10 ticks per group. Tick mortality, reproductive index (RI), and inhibition of oviposition (IO %) were measured at 24 hours, 7 days, and 14 days post-treatment (PT). Statistical analysis was conducted using the probit method, with a significance level of p < 0.05. The results showed that both the aqueous extract and EO of M. charantia exhibited low acaricidal activity. Even at the highest EO concentration (20%), only 45% tick mortality was observed. The effect on oviposition was negligible, as the aqueous extract did not inhibit oviposition in live engorged female ticks. Consequently, M. charantia may not be a suitable alternative to synthetic acaricidal agents available on the market.
Le projet architectural à travers une pensée croisée entre l'art et la science
Authors: Zair Kaouthar
Published: September 2023

L’enseignement de l’architecture se présente comme un carrefour d’échange interdisciplinaire, qui ne se base pas seulement sur le volet pratique, mais qui comporte une approche théorique faisant appel aux notions et références développées dans les cours théoriques. Il se présente ainsi comme un laboratoire de recherche et d’expérimentation sur l’architecture dans son écriture extérieure et intérieure en tant que discipline intégrant la forme et l’espace, développant des approches pédagogiques interactives et complémentaires. Le choix d’un dispositif pédagogique comme prétexte pour aborder l’interdisciplinarité dans le projet architectural devrait en conséquence être bien réfléchi avec un cheminement méthodologique ciblé qui permettrait d’explorer la synergie entre architecture et ingénierie, architecture et design de l’espace, architecture et sculpture, architecture et urbanisme. Faire intervenir les spécialistes tels que plasticien, ingénieur, historien, sociologue, conservateur du patrimoine et urbaniste dans la conception d’un projet architectural ne peut qu’enrichir les connaissances de l’apprenant et développer chez lui un esprit de collaboration et d’échange.
Estimating Classification Accuracy for Unlabeled Datasets Based on Block Scaling
Authors: Shingchern D. You  , Kai-Rong Lin  , Chien-Hung Liu
Published: September 2023

This paper proposes an approach called block scaling quality (BSQ) for estimating the prediction accuracy of a deep network model. The basic operation perturbs the input spectrogram by multiplying all values within a block by , where  is equal to 0 in the experiments. The ratio of perturbed spectrograms that have different prediction labels than the original spectrogram to the total number of perturbed spectrograms indicates how much of the spectrogram is crucial for the prediction. Thus, this ratio is inversely correlated with the accuracy of the dataset. The BSQ approach demonstrates satisfactory estimation accuracy in experiments when compared with various other approaches. When using only the Jamendo and FMA datasets, the estimation accuracy experiences an average error of 4.9% and 1.8%, respectively. Moreover, the BSQ approach holds advantages over some of the comparison counterparts. Overall, it presents a promising approach for estimating the accuracy of a deep network model.

Due to the growing demand for photovoltaic power generation systems for grid-connected renewable energy systems, the high-quality energy and the good efficiency are necessary. For this reason, two-level parallel inverters are used in grid-connected PV systems connected to standard AC and DC connections are widely utilized. This structure is often relied on to raise the quality of the power and increase the power conversion efficiency. This article proposes a grid-tied energetic system composed of a photovoltaic source connected to the grid by the means of DC-DC boost converter controlled by hell clamping algorithm MPPT to improve the harvesting of the PV power, and of two VSIs connected in parallel interfaced by a coupling filter and controlled by two methods namely, classic DPC-PI and improved DPC-ST. An extensive simulation analysis was carried out to validate the proposed control approach by the comparison with the conventional method base on PI regulator. The proposed technique introduced a superior performance in terms of lower voltage stress at the DC-link, the THD of the injected current, and the ripples of the active and reactive power.

Passivity-based control is a well-known strategy for synthesizing stable controllers because it models and manages systems based on their global state space equations. It also permits proving the system's stability by making it passive, which is an undeniable advantage over traditional controllers that have limitations in terms of applications, saturation, and the inability to verify stability. Previous research used nonlinear control based on passivity method to control the energy distribution between the embedded sources, they did not investigate the impact of the dumping matrix parameter, which was typically considered to be a positive random value. In contrast, the results of this investigation show that it significantly affects system behaviour, especially in the transient-state domain. The primary objective of this study is to develop and evaluate an energy management strategy for hybrid electric vehicles powered by Fuel Cells as the primary source and Supercapacitors as the secondary source. The fast response with less overshoot is ensured by optimizing the damping matrix parameter using a well-known optimization technique named Novel Equilibrium Optimizer. The proposed technique is successfully demonstrated in a Matlab® simulation environment, and the control system exhibits robust dynamic behaviour. Finally, despite the complexity of this technique's mathematical proof, it provides a simple, efficient feedback control law for a real electrical vehicle application.

In this article, we carried out a study on the behaviour and efficiency of an oscillation-damping system, mounted on the driving axles of railway vehicles to mitigate stick-slip oscillations. The occurrence of the stick-slip phenomenon is particularly harmful in operation because it generates wear on the tread surfaces of the wheels and rails, generates fatigue stresses in the axles and diminishes locomotive performance. To reduce these inconveniences, we proposed installing on the axles a damping system to reduce stick-slip oscillations and studied the behaviour and the efficiency in the operation of this system.

The Unified Power Flow Controller (UPFC) is one of such emerging FACTS devices that can manage the power flow in Transportation System. Based on the control system associated with the management of UPFC, both the controllers of shunt and series converters of UPFC are controlled conventionally using PIs controllers. However, the PI system alone cannot control the UPFC in the presence of uncertainty of system parameters and disturbances. For this reason, the use of novel robust techniques based on artificial intelligence theory in the design control of UPFC is very efficient for improving its performances. In this regard, four approaches have been used in this study to replace the conventional PI controller and enhance the performance of the UPFC for power flow reference tracking. In the first approach, the fuzzy logic technique (Mamdani and Sugeno types) has been employed to provide dynamic control of series and shunt converters of UPFC, whereas in the second method, the controllers of UPFC are performed through the optimization techniques such as: PSO, PSO_SQP, and GA techniques. The proposed techniques based UPFC are tested in MATLAB/Simulink software by using UPFC with a 48-pulse voltage source converter (VSC) equipping a High Voltage (HV) electrical network. In terms of dynamic performance, the simulations’ results and the comparative analysis clearly show the superiority of the intelligent controllers regardless of the variation of powers that affecting the model plant. Compared to PI controller, they ensure good performance in terms of tracking and decoupling.

Published: September 2023

Islam as a religion has been found to impact the ethical beliefs and behaviours of Muslim consumers from different countries, as well as consumers’ choice of services and some taboo products on the basis of Islamic Shariah law. The emergence of Islamic marketing and Islamic branding in various parts of the world and the increasing middle-class Muslims in Indonesia are interesting phenomena to study. Using the qualitative approach, this study aims to explore the development of Islamic marketing, Islamic branding, and middle-class Muslim in Indonesia. The results showed that Islamic marketing is still new in the literature and the definition of the true meaning of Islamic marketing is still being developed. In addition, Islamic branding is closely related to the halal concept. The behaviour of Muslim middle-class in Indonesia is very challenging and it has enormous potential. The discussions are explained further.

Published: September 2023

A educação patrimonial é imprescindível para conhecer e reconhecer os patrimônios, a cultura, a história e a memória de diversos grupos. Contudo, o conceito de patrimônio cultural se modificou e se ampliou ao longo do tempo, e, nesse movimento, não só bens artísticos e históricos são valorizados e reconhecidos, mas também as mais diversas formas de tradições. Em Ervália, Minas Gerais, os bens tombados são de origem elitista e religiosa, porém, eles e as mais variadas tradições culturais poderiam ser utilizados de forma crítica e construtiva no processo de ensino-aprendizagem, principalmente na educação patrimonial. Nesse sentido, o presente trabalho buscou averiguar como a educação patrimonial ocorre na prática em escolas estaduais do município, onde foi enviado um questionário aos educadores que nelas atuam, para averiguar informações, aprofundar análises e construir sínteses. Com as respostas dos educadores, novos conhecimentos podem ser pensados e construídos para o processo educacional, levando em consideração o que os educandos já sabem. Algumas propostas de intervenções também foram apresentadas, direcionadas a uma boa condução de práticas educativas que envolvam educandos, educadores e a população do município em torno da educação patrimonial.

Published: September 2023

Este trabalho caracteriza-se como uma pesquisa qualitativa, exploratória e participante, resultante da análise de um recurso pedagógico denominado “Rodas de Conversa”, realizado por uma escola da rede privada do interior de Minas Gerais durante o período do ensino remoto. Portanto, objetivou-se analisar as diversas vozes que compuseram as rodas de conversa com alunos do Ensino Fundamental. O material empírico consistiu em entrevistas semi-estruturadas realizadas com um grupo de 33 participantes (entre eles, 3 membros da coordenação pedagógica, 10 professoras, 1 pai e 9 mães e 10 alunos). Em uma perspectiva dialógica, elegemos o Construcionismo Social como nosso aporte teórico, bem como as contribuições de Paulo Freire, patrono da educação brasileira, a partir da sua proposta de uma educação libertadora. Na revisão de literatura, buscamos publicações no banco de periódicos da CAPES que buscaram analisar trabalhos com rodas de conversa no âmbito da educação básica e da formação continuada de professores nos últimos anos. Como metodologia, a análise temática das entrevistas possibilitou a visualização de alguns aspectos, que destacamos ao longo da pesquisa. Após essa etapa, obtivemos quatro principais categorias – rodas de conversa como: mecanismo de interação pessoal; recurso socioemocional; espaço para aprender valores e, por fim, de desenvolvimento de competências e habilidades diversas. Além disso, dentro dessas categorias, elegemos subcategorias que se relacionavam diretamente como elementos presentes nas falas dos entrevistados. Ademais, a investigação realizada nos mostra o anseio pelo retorno ou existência de um recurso que leve os alunos a conversarem sobre emoções, sentimentos e diversos outros temas que os participantes consideram necessários para o debate entre os pares. Colocar-se em diálogo nas escolas: eis um desafio, porém uma necessidade do século XXI no campo da educação e acreditamos que a criação de rodas de conversa podem ser estratégias importantes neste sentido.

The study of the asymptotic behavior of an entire transcendental function of the form f(z) = Pn anzpn, pn ∈ N, on curves γ going to infinity arbitrarily, is a classical problem, goes back to the works of Hadamard, Littlewood and Polia. Polia posed the following problem: under what conditions on pn does there unbounded sequence {ξn} ⊂ γ exist such that lnMf(|ξn|) ∼ ln|f(ξn)| for ξn → ∞ (Polya’s problem). Here Mf(r) is the maximum of the modulus f on a circle of radius r. He showed that if the sequence {pn} has zero density and f is of finite order, then the indicated relation between lnMf(|ξn|) and ln|f(ξn)| is always present. This assertion is also true in the case when f has a finite lower order: the final results for this case were obtained by A.M.Gaisin, I.D.Latypov and N.N.Yusupova-Aitkuzhina. We consider the situation when the lower order is equal to infinity. A.M. Gaisin received an answer to Polia’s problem in 2003. This is the criterion. If the conditions of this criterion are satisfied not by the sequence {pn} itself, but only by a subsequence — a sequence of central exponents, then the logarithms of the maximum modulus and modulus of the sum of the series will also be equivalent in the indicated sense on any curve γ going to infinity.

The paper proposes a mathematical model for describing the movement of the working body of the plow, taking into account the vibration effect. The model is used to simulate the movement of the working body of the plow with an uneven speed of the traction unit. It was found that when accelerating, a stationary displacement of the working body of the plow occurs, as well as a decrease in the amplitude of oscillations and an exit to a stationary mode with a small amplitude of several millimeters. The specific power also reaches a stationary value over time. The parameters of steady oscillations depend on the stationary value of the speed of movement and the properties of the soil.

В статье рассматриваются вопросы оценки бюджетной обеспеченности арктических регионов с целью выравнивания доходов и повышения благосостояния населения. Проведен анализ объективных и субъективных факторов, влияющих на пространственную дифференциацию арктических регионов в рамках проводимой государственной политики по выравниванию бюджетной обеспеченности. Выполнены сравнительный анализ и оценка влияния показателей уровня бедности и среднемесячной заработной платы при расчете индекса бюджетных расходов в разрезе групп арктических регионов. На основе Методики выравнивания бюджетной обеспеченности с учетом новаций, введенных с 2023 г., дана оценка изменения индекса бюджетных расходов арктических регионов. Выявлена тенденция к изменению подходов в государственной политике выравнивания бюджетной обеспеченности арктических регионов в пользу субъективных факторов пространственной дифференциации с учетом финансово-экономических условий, сложившихся диспропорций в социально-экономическом развитии регионов, неоднородности бюджетных обязательств и бюджетного финансирования. Учитывая необходимость влияния промышленного освоения Арктики на повышение качества жизни народов Севера и народосбережение, предлагается усилить вовлеченность добывающих компаний в решение социально-экономических задач развития арктических территорий и поддержки местного населения на основе социального инвестирования таких компаний в районах своей деятельности.
Новое в раскрытии финансовой информации, связанной с устойчивым развитием в концепции ESG (версия МСФО)
Authors: Афанасьев М.П. , Шаш Н.Н.

В статье рассматриваются вопросы формирования финансовой и нефинансовой отчетности в рамках процесса конвергенции глобальных систем финансовой отчетности US GAAP и IFRS. Приведены результаты сравнительного анализа основных концепций систем нефинансовой отчетности в корпоративном секторе экономики. По результатам проведения контент-анализа выявлены основные барьеры, тормозящие внедрение в корпоративном секторе систем нефинансового учета и нефинансовой отчетности в рамках глобальных систем финансовой отчетности. На основе анализа официальной статической информации сделан вывод, что в России наблюдается общемировой тренд, отражающий некоторое снижение количества представленных корпоративных нефинансовых отчетов. Обосновано, что формирование единых стандартов системы нефинансовой отчетности, которая сможет наиболее полно отражать отраслевую специфику компаний, не только повысит качество предоставляемой отчетной документации и ее сопоставимость, но и позволит использовать нефинансовую информацию в бизнес-практике, формируя новые прогрессивные бизнес-модели, ориентированные на устойчивое развитие и наиболее полный учет принципов ESG в деятельности. Выявлено, что основным препятствием для устойчивого корпоративного поведения следования ESG принципам является гибкий подход, поскольку его применение не формирует реальных стимулов для проведения более эффективной корпоративной политики в сфере устойчивого развития. Сделан вывод, что в текущих условиях внимание следует сосредоточить на подготовке унифицированных стандартов нефинансовой отчетности, интегрированных в действующие глобальные и национальные системы финансовой отчетности. Доказано, что отдельный акцент необходимо сделать на формировании нормативной базы для включения метрик и индикаторов, оценивающих результаты деятельности компании в сфере устойчивого развития, в публичную корпоративную нефинансовую отчетность.

Published: September 2023

В работе рассматривается проблема оценки эффективности субсидий для авиатранспорта в России с точки зрения привлечения дополнительного пассажиропотока. В области внимания, прежде всего, находятся региональные авиамаршруты, не включающие г. Москву. Для оценки эффектов использована обширная база данных по авиамаршрутам в России, размеру субсидий авиаперевозчикам, региональным макроэкономическим показателям в период 2012-2021 гг. Статистические гипотезы тестируются на основе моделей панельных данных, логистической регрессии. По результатам анализа можно говорить о том, что наблюдается статистически значимый эффект субсидирования авиамаршрутов в России с точки зрения изменения пассажиропотоков. При этом реакция на субсидии по различным авиамаршрутам разная. Среди них выявлено несколько типовых кластеров, различающихся степенью эластичности пассажиропотока по субсидиям. На основании модели бинарного выбора сформулирован «обратный» тест для оценки статистической значимости субсидий, также подтвердивший сделанные выводы.

Lack of instructional materials like computers was determined as one of the problems the ALS itself has faced therefore, this study objectified the basic computer skills among Alternative Learning System (ALS) Learners in San Jose, Dinagat Islands. 51 ALS learners comprised the respondents’ group and the assessment was conducted at Sta. Cruz, San Jose, Dinagat Islands. Results revealed that majority of the ALS learners had good knowledge of operating Windows, while a large percentage of them cannot effectively operate the Microsoft Word software with little to no knowledge of creating and editing documents. On the other hand, learners were determined to be beginners whose knowledge of operating emails and the internet were insufficient and were less exposed to learning Excel as this has found more complicated to use. However, ALS learners showed positive personal interest in learning computers despite their inability to own one due to socioeconomic or situational. Thus, it may recommend that the government must support the ALS program by providing an adequate number of computer facilities to cater to all the ALS learners and better enhance their level of basic computer skills, particularly in areas of General Windows, Microsoft Word, MS Excel or Spreadsheet and Internet/E-mail. Significantly, the DepEd needs to closely monitor the ALS program as its parallel learning system, so that out-of-school youth are provided with improved learning opportunities in all areas, especially in ICT.

The purpose of this research is to find out the method of calculating Zakat company in KSPPS Bakti Huria Syariah based on maslaha and the role of Zakat in increasing business continuity. The type of research used was qualitative research with a phenomenological approach, which is located at KSPPS Bakti Huria Syariah on Jln. Malengkeri. The results showed that the company’s zakat provisions in KSPPS Bakti Huria Syariah are based on AD/ART where the amount of zakat issued is based on the profits earned deducted by the obligation multiplied by 2.5% every month at each branch which is then collected at the head office. Maṣlaha-based zakat consists of two components, namely profits and blessings, blessings obtained, namely the blessings of heaven in the form of rewards at the end of the day, blessings on earth in the form of positive images obtained from the community, loyalty and productivity from employees. In addition, the role of zakat in increasing business continuity can be seen from KSPPS Bakti Huria Syariah getting a positive image from the community which in the long term will increase profits, from a capital and financial aspect since the transfer of KSPPS Bakti Huria Syariah has increased from the number of branches of 25, an increase in the number of members, from the aspect of human resources, the provision of training facilities for skill development, religious studies and the provision of educational facilities for branch heads. The implications of this research are expected to be a source of development and application for other researchers, especially those related to the method of calculating corporate zakat, corporate zakat based on maslaha, and the effect of zakat on business continuity. In addition, this research is expected to be able to become a basis for the government or related institutions to make more binding regulations.

Positive living and social support are crucial factors that possibly enhance the wellbeing of perpetually professed consecrated women as they endeavor to serve God and humanity. This research attempted to investigate the relationship between positive living and social support among perpetually professed consecrated women in the Archdiocese of Nairobi, Kenya. The study addressed four objectives; to examine the levels of positive living, to investigate the levels of social support, to examine the relationship between demographic characteristics and positive living, and to establish the relationship between positive living and social support among perpetually professed consecrated women in the Archdiocese of Nairobi, Kenya. The participants were 320 perpetually professed consecrated women. The study used the correlational research design. It used proportionate stratified random sampling technique and simple random sampling technique. Positive Living Scale and Berlin Social Support Scale were used. Data was analyzed using SPSS version 25. Findings revealed that 54.8% (n = 176) of the respondents scored a high level of positive living, 34.6% (n = 110) of the respondents scored a moderate level of positive living, while 10.6% (n = 34) had a low level of positive living. On social support, findings showed 48.4% (n = 151) of the participants had a high level of social support, 44.6% (n = 144) scored a moderate level of social support, while 7% (n = 25) of the participants were at a low level of social support. The study established that there was a weak positive relationship between positive living and social support among perpetually professed consecrated women in the Archdiocese of Nairobi, Kenya (r = .104; P = .042). The study recommended that superiors of religious communities may try to be physically available, and also be ready to listen to their members and be able to understand them in order to enhance good emotional wellbeing that may enhance positive living. The study further recommended that the perpetually professed consecrated women in the Archdiocese of Nairobi Kenya, who were at low and moderate levels of positive living and social support, may be helped in counseling and psychological assessments so as to identify issues that could be responsible for low and moderate levels.
