The research included an introduction, and a preface in which he talked about Ibn Hisham and his book Al-Mughni, and Shihab Al-Khafaji and his book jokes, and two sections, The first section was devoted to his diligence, and his grammatical doctrine, and made in two requirements: the first: for his efforts and diligence, and the other: for his grammatical doctrine, and the second section was devoted to: evaluating those intakes, And made in two requirements: the first: for the reasons of the drawbacks, and the other: for the grammatical assets that relied on them in the drawbacks, and concluded the research with a conclusion in which the most prominent results were included. The research took the descriptive approach and the analytical approach as an approach. The research reached results, including: that many of the books of Al-Khafaji, may God have mercy on him, are still in manuscript, and that he was free in his choices not affiliated with others, and in many matters of disagreement tended to the Basrians, and agreed with them, and that he did not explain everything that came in Al-Mughni’s text.
Arabic And Western Rhetoric: A Conceptual Introduction To Argumentation Critical Discourse Analysis
Authors: Ramadan Ibrahim , Alkhamis Abdulrahman
Published: March 2024

This paper aims to present a theoretical approach to studying the Argumentative study, also known as modern rhetoric, the paper has followed a limpid path moving between the various definitions of argumentation using the descriptive-analytical method. Firstly, it differentiates the two types of argumentation: the logical and the linguistic. Then, it deals with the most well-known contextual definitions of argumentation in both Arabic and Western argumentative studies. Aristotle was the first to refer to the types of argumentation. Hence, the paper shows his endeavors in this respect. The article contributes to the advancement of Arabic language and teaching by providing theoretical foundations, pedagogical insights, cross-cultural understanding, historical context, methodological applications, relevance to modern scholarship, and the validation of Arabic rhetorical traditions. This study aims to give a brief and easy idea of Aristotle's efforts in the field of argumentation, especially the logical arguments and the subjective moral arguments, and the functions of these moral arguments of benefit, influence, and enjoyment, whether they relate to the orator (Aetos), the audience (Pathos), or the speech itself (Logos). Then, the research concluded with examples of these self-created arguments. The study results showed a comprehensive concept of the arguments in Arab and Western thoughts. Moreover, the researchers proved that Aristotle's topics and thoughts were one of the greatest sources of nourishment for the modern argumentative lesson; Arabic rhetoric did not lag behind the Western lesson in its care for argumentations and its methods of analysis, and they demonstrated the applicability of the mentioned concepts in the study.

Published: March 2024

Online learning needs to humanize the experience, especially in this day and age when technology is upending our lives and curriculum delivery methods are evolving quickly with new tools and applications. It is crucial, therefore, to humanize both our instruction and our students' learning at disruptive moments. This study aimed to investigate how Al-Madinah International University (MEDIU) undergraduate students experienced humanizing learning in a virtual learning environment. The researchers use a sequential mixed-method methodology to collect information for their analysis of the humanization of education in virtual learning environments. (320) undergraduate students from Al-Madinah International University participated in the quantitative portion of the study by answering both open-ended and closed-ended questionnaires. The qualitative data was analyzed using a thematic method, and the results were used to support the quantitative findings by creating themes using ATLAS ti. The quantitative data was analyzed using descriptive statistics. According to the study's findings, 87% of respondents said that humanizing education in a virtual learning environment had been successfully applied, while the remaining respondents were unsure. According to the qualitative data, most ODL instructors must attend training on using humanizing education in virtual learning environments. During the module compilation process, the participants suggested that ODL programs incorporate the cultural information students have learned at home and in their communities. Given that most respondents have an Arabic language background, the curriculum needs to consider their culture. Students from Arabic and Islamic backgrounds, in particular, should have their culture at the center of lectures in the virtual learning environment, according to the institution.

Percepciones de salud materno-infantil y efectos de incentivos económicos en los Altos de Chiapas, México: Análisis Post-Prospera
Authors: Morales-Domínguez Magdalena del Carmen
Published: March 2024

Objetivo: Analizar las percepciones de mujeres indígenas y personal de salud en los Altos de Chiapas tras Prospera, para visibilizar cómo el programa cambió la atención de la salud materno-infantil, específicamente en relación con la presencia o ausencia de incentivos económicos.
Material y Método: El estudio, basado en la teoría fundamentada, utilizó nueve entrevistas grupales con mujeres (54 participantes) y nueve entrevistas semiestructuradas con siete enfermeras y dos médicos.
Resultados: La relación entre las mujeres y el personal de salud en el marco de Prospera fue percibida como una obligación motivada por un incentivo económico, en lugar de ser vista como una corresponsabilidad. Los temas de intervención, como las pláticas de orientación en salud y las consultas médicas que implicaban la asistencia a la unidad médica, al finalizar el programa la mayoría de las mujeres dejaron de asistir. Este cambio en la dinámica sugiere que la relación construida en torno al incentivo económico no logró fomentar una corresponsabilidad sostenible en el cuidado de la salud materno-infantil, después de la conclusión de Prospera.
Conclusiones: En el programa Prospera, se observaron ventajas como el monitoreo de la salud materna, pláticas de salud y la provisión de suplementos vitamínicos. Sin embargo, la falta de una corresponsabilidad efectiva y la percepción de obligación condicionada al incentivo económico, influyeron en la disminución de la asistencia a las unidades médicas y en la adopción de prácticas de cuidado preventivo, lo que podría minimizar todas las ventajas obtenidas. Este hallazgo resalta la importancia de diseñar intervenciones sociales, que vayan más allá de la mera obligación y fomenten una participación activa y sostenible en el cuidado de la salud materno-infantil.

Alî Nazîf’in Miftâhu’l-Bedâyi’den Tercüme ve Telif Yoluyla Ürettiği Belâgate Dair Eserler
Authors: AKDAĞ Ahmet
Published: March 2024

Fars edebiyatında edebî sanatlar ve bazı şiir terimlerini ele alan eser yazma geleneği Râdûyânî (öl. 507/1114’ten sonra)’nin Tercümânü’l-Belâga’sı ile başlayıp Reşîdüddîn Vatvât (öl. 573/1177)’ın Hadâiku’s-Sihr fî Dekâiki’ş-Şi‘r adlı eseri ile önemli bir merhaleye ulaşmıştır. Vatvât’ın eseri konuyla ilgili kendisinden sonra yazılan eserlerin temel başvuru kaynakları arasında yerini almıştır. Vahîd-i Tebrîzî’nin Miftâhu’l-Bedâyi isimli eseri de Vatvât’ın eserinin tesiriyle edebî sanatlar ve bazı şiir terimleri üzerine kaleme alınan eserlerdendir. Bu eser, 19. yüzyılın ikinci yarısı ile 20. yüzyılın ilk yarısında yaşamış müelliflerden Alî Nazîf tarafından Tercüme-i Miftâhu’l-Bedâyi adıyla 1300/1882-83 yılında Türkçeye tercüme edilmiştir. Alî Nazîf, altı sene sonra bu tercümesini esas alarak Zînetü’l-Kelâm adlı eserini yazmıştır. Zînetü’l-Kelâm’da daha önce yazdığı tercümesine bazı eklemelerde bulunmuş ve tercümenin bazı kısımlarını eksiltmiştir. Her iki eser detaylı olarak analiz edildiğinde Zînetü’l-Kelâm’ın müstakil bir telif olmaktan ziyade daha önce yazılan tercümeden üretilen bir telif olduğu görülmektedir. Osmanlı telif geleneğinde başka dilden bir eserin Türkçeye aktarılması esnasında kaynak metne ilaveler yapma ve kaynak metinden eksiltme veya özetlemelerde bulunma geleneği çokça başvurulan bir usuldür. Söz konusu eserlerin tercüme addedilmesi yeterli olmadığından araştırmacılar tarafından bu eserleri ifade etmek için telif-tercüme terimi önerilmiştir. Alî Nazîf’in Zînetü’l-Kelâm’ı da telif-tercüme görünümüne sahip bir eserdir. Ancak bu eser, doğrudan kaynak bir metin yerine müellifin daha önce Miftâhu’l-Bedâyi üzerine yazdığı tercümesinden üretilmesi yönüyle tercümeden telif mahiyetindedir. Temelde bu hususları ele alan çalışmamız, iki bölümden müteşekkildir. Çalışmanın birinci bölümünde yaşadığı yüzyıl ve vefat tarihi konusunda kaynaklarda birbirinden farklı tarihler öne sürülen Vahîd-i Tebrîzî’nin yaşadığı zaman dilimi çeşitli karinelerden hareketle tespit edilmeye çalışılmış ve eserleri hakkında bilgi verilmiştir. Yine bu bölümde Alî Nazîf’in de hayatı ve eserlerine de kısaca değinilmiştir. İkinci bölümde ise Miftâhu’l-Bedâyi tercümesinde uygulanan yöntem ve bu tercümeden üretilen telif bir eser olması yönüyle Zînetü’l-Kelâm üzerinde durulmuştur.
Protestplätze, Partizipationsräume, Parallelwelten : wissenschaftliche Betrachtung und aktuelle Bewertung von Alternativmedien
Authors: Kast Matthias
Published: March 2024

Von links bis rechts, von partizipationsfördernd bis demokratiezersetzend; es gibt sie in diversen Ausformungen und in jedem Mediensystem; sie sind wie der professionelle Journalismus bedeutsam, werden aber vielfach als unqualifiziert abgetan: Alternative Medien. Da sie bis heute verschiedenste Zuschreibungen erfahren, tut sich die Wissenschaft schwer, zeitgenössische Alternativmedien zu erklären; für die Gesellschaft bleiben deren Entstehen, Bestreben und Bedeutung oft nebulös. Dies ist problematisch, vermag doch erst das Wissen über Alternativmedien das zeitgenössische Mediensystem vollumfänglich begreifbar zu machen. Daher widmet sich diese Arbeit dem Thema aus einem theoretischen Blickwinkel. Sie greift auf bestehende Werke zu Alternativmedien zurück und verwertet sie für eine aktuelle Definition und Bewertung. Die Studie zeigt, dass das heterogene Feld der Alternativmedien heute Standpunkte sämtlicher Ideologien kennt, verbindendes Element aber allzeit die Kritik an den klassischen Medien ist. Gleichwohl weisen zeitgenössische Alternativmedien wesentliche Gemeinsamkeiten zu ihren „Antagonisten“ auf. Im Ergebnis trägt die Arbeit zum besseren Verständnis und zur theoretischen Fortentwicklung des Gegenstandes bei.

Authors: Silva Pedro Felipy Cunha da , Araújo Wagner Junqueira de
Published: March 2024

Introdução: Um avançado processo de transformação digital já estava em curso, quando recebeu o impacto da ampliação do trabalho remoto durante e após a pandemia de COVID-19. Objetivo: Este estudo buscou compreender como estão sendo gerenciados os metadados de preservação relacionados aos registros digitais arquivísticos das instituições federais de ensino superior brasileiras. Metodologia: Parte de um estudo de caso do Centro de Ciências Jurídicas da Universidade Federal da Paraíba e da aplicação de pesquisa junto às Instituições Federais de Ensino usuárias do software SIPAC Protocolo, por meio de um questionário enviado para dezesseis instituições. As respostas foram tabuladas utilizando o software Microsoft Excel, e posteriormente analisadas com o auxílio do software Rapid Miner. Resultados: Obteve-se uma descrição dos metadados armazenados, com a diferenciação daqueles gerados de forma automática dos inseridos manualmente pelo usuário. Conclusão: Observou-se que esses metadados, quando associam as transações e requisitos, validam o registro produzido, permitindo que os dados nele constantes possam se tornar um documento manifestado e acessível ao usuário no decorrer do tempo.  Esse processo nem sempre cria um registro digital arquivístico; apenas quando evidencia e serve de prova das atividades de uma pessoa ou instituição. Foi possível notar ainda que o caráter dinâmico dos recursos digitais requer a reunião de informações com nível de segurança razoável, garantindo que o ambiente computacional no qual a informação foi criada poderá ser reproduzido com o passar do tempo. Desta forma, os registros permanecerão acessíveis, independentemente da existência do formato e das condições técnicas em que foram concebidos.

L’alignement pédagogique en pharmacie clinique permet-il de renforcer l’autonomie des étudiants ? Retours d’expérience, stratégies et perspectives
Authors: Breilh Dominique
Published: March 2024

L’alignement pédagogique, basé sur l’approche par compétences, consiste à harmoniser les objectifs d’apprentissage, les méthodes d’enseignement, les évaluations et les retours, créant ainsi un continuum cohérent d’expériences éducatives. Cependant, cette approche ne se limite pas à la synchronisation des éléments du parcours universitaire ; elle s’étend également à la promotion de l’autonomie des étudiants, les encourageant à devenir des professionnels de santé indépendants et formés aux évolutions des activités pharmaceutiques qui s’ouvrent à eux. Dans le cadre du dispositif NewDEAL, sur une période de sept mois (octobre 2022 à avril 2023) et à l’aide d’un accompagnement personnalisé de la part d’une ingénieure pédagogique de la MAPI (Mission d’Appui à la Pédagogie et à l’Innovation, université de Bordeaux), j’ai mis en place les objectifs d’apprentissage ainsi que les grilles critériées d’évaluation. Cet alignement pédagogique s’inscrit dans le cadre de mes enseignements en formation initiale de la 2e année jusqu’à la 6e année des études de pharmacie à l’université de Bordeaux ainsi que pour les activités en pharmacie clinique durant les stages hospitaliers. Le plus délicat reste toutefois les étapes de communication, de sensibilisation auprès des pairs ainsi que les travaux concernant l’évaluation. Cet article a pour objectif de communiquer sur la mise en place réussie de l’alignement pédagogique et ses premiers retours d’expérience dans le domaine de la pharmacie clinique.

Time Expansion Wave Theory—A New Approach to Understanding the Universe and Its Expansion
Authors: Jarvis G K
Published: March 2024

We review time expansion wave theory and refine our model showing it to accurately match observed cosmological luminosity data. The theory augments general relativity to create a container within which quantum effects can be explained by treating time as an artefact of a fourth spatial dimension that we observe as the expansion of the universe. This leads us to explain mass creation, the speed of light limit, gravity, black holes without singularities and other macroscopic effects. Our model leads to an expansion velocity of 6.87 0.36 × 106 ms-1, which results in a Hubble expansion rate constant of 71.3 3.7 km/s/Mpc. Because of the finite window of time in which we exist, an extra a degree of freedom is available leading to interesting interpretations at the subatomic level. At this size range, then a spin is allowed within the time dimension explaining why wave particle duality occurs and explains the electromagnetic force and other quantum mechanical properties. It provides a solution to the double slit conundrum and can explain how quantum entangled partners can behave in a quantum way and pass seemingly time-defying information. The potential quantitative origin of the fine structure constant which governs the size of the electromagnetic force is also strongly indicated by this theory.

Authors: Pérez-Terrazo Andrés , Moreno Martin , Trejo-Zúñiga Iván , López J. Alberto
Published: March 2024

Wind turbines are a solution for sustainable energy, significantly reducing carbon emissions and fostering a circular economy for more cost-effective and cleaner power generation, in line with worldwide environmental aspirations. In this context, this research aims to explore a novel Two-Stage Twisted Blade micro-Vertical Axis Wind Turbine ($\mu$-VAWT) alternative inspired by the Savonius Rotor (SR). This investigation utilizes the $\kappa-\omega$ SST turbulence model to explore the power coefficient ($C_P$) and torque coefficient ($C_T$), finding $C_P$ values ranging from 0.02 to 0.04 across the turbine by altering the free stream velocity ($V$). $C_T$ analysis further delves into four specific sections, highlighting areas of particular interest. These results are validated by examining velocity contours, pressure contours, and streamlines in four horizontal sections, demonstrating that the proposed turbine model exhibits minimal torque fluctuation. Moreover, the analysis of vertical wind streamlines illustrates very low interference with various wind turbine proposals, underscoring the turbine's efficiency and potential for integration into diverse wind energy projects.

Authors: Havadar Tarkan , Kalkavan Arslan , Özen Gökmen
Published: March 2024

The purpose of this study is to investigate the effect of trainer behaviors on the anger and aggression levels of athletes. This study was conducted with 748 athletes with an active license who are over 18 years of age and participate in individual and team sports branches. In this study, the "Coaching Behavior Assessment Questionnaire" and the “Competitive Aggressiveness and Anger Scale" were used as data collection tools. The study results showed that athletes’ levels of evaluation of the trainers' behaviors were high, while the levels of aggressiveness and anger in sports were low. It was determined that there is a negative low-level relationship between the athletes’ evaluation levels of the trainers' behaviors and the aggressiveness and anger levels in sports and that the trainer's behaviors predict the anger and aggressiveness levels of the athletes by 9% and 6%, respectively. The results of this study show that the attitudes and behaviors of trainers can affect the emotional states of athletes and have the potential to increase or decrease their anger and aggressiveness levels. Trainers who exhibit positive, supportive, and modeling behaviors help create a healthy sports environment and help athletes maintain emotional balance.

Published: March 2024

SOC stock (SOCS) changes caused by land use changes are still unclear, and understanding this response is essential for many environmental policies and land management practices. In this study, we investigated the temporal-spatial and vertical distribution characteristics of SOCS on the Western Sichuan Plateau (WSP) using the sparrow search algorithm-random forest regression (SSA-RFR) models with excellent model applicability and accuracy. The temporal-spatial varia-tions in the SOCS were modeled using 1080 soil samples and a set of nine environmental covariates. We analyzed the effect of land use changes on the SOCS on the WSP. The total SOCS increased by 18.03 Tg C from 1990 to 2020. The results of this study confirmed that the SOCS in the study area has increased significantly since 2010, with an increase of 27.88 Tg C compared to the total SOCS in 2010. We found that the spatial distribution of the SOCS increased from southeast to northwest, and the vertical distribution of the SOCS in the study area decreased with increasing soil depth. Forest and grassland are the main sources of SOCS, the total SOCS in the forest and grassland accounted for 37.53 and 59.39% of the total SOC pool in 2020, respectively. Expansion of the wetlands, forest, and grassland areas could increase SOCS in the study area.
Artificial Intelligent to Combat Loneliness and Social Isolation in Japan an Aid or Cure
Authors: J Guruprakash , L.B Krithika
Published: March 2024

Loneliness is becoming prevalent across Japan in spite of its a dense population and communal culture. Surveys show 40% of adults report isolation across demographics. The contradiction emerges due to deteriorating social structure with modernization, economic parity, urbanization, and fading conventional setup. The continually social withdrawals, called “hikikomori." Relief seekers have embraced AI based emotive robots, digital avatars, and immersive VR as low-stakes social surrogates despite limited capacity to cultivate human intimacy. To stabilise government attempts awareness through reforms, scheme and support services. But a concrete transformation can be brough in with work-life balance, gender equality and rewire the metrics for self-esteem. Even a perfectly personalized AI cannot replace the human affection lacking in the society. Lasting solutions demand technological aids be balanced by confronting and reinventing community purpose and bring in structural change. Overall Japan’s endemic isolation reveals the societal fraying when modernization privileges independence over interdependence. The path forward rests on restoring cultural foundations to reverse loneliness and social isolation.

This study concerns the transport and retention of polydisperse micron-sized (16 ± 6 µm) of microplastics (MPls) in porous media under varying flow rate conditions. Sorption kinetics were modeled using first-order reversible and irreversible kinetic sorption models, with sensitivity analyses providing insights into each sorption parameter's effect. Both numerical modeling and experimental measurements were employed to assess sand filter retention rates. The impact of flow rate on sorption reveals variations in distribution coefficient (Kd), mass transfer coefficient (β), and irreversible sorption rate (K1). Lower flow rates are correlated with higher Kd and β values, indicating an increase in sorption and diminished mass transfer rates. The findings revealed that an increase in Kd resulted in a more gradual sorption process with a decrease in peak concentration, whereas changes in β influenced the rate of sorption and peak concentration to a lesser extent compared to Kd. Lower K1 values are associated with higher peak concentrations and decreased retention efficiency. Retention rates were evaluated by a numerical model and found as 28 ± 1% at a flow rate of 31 ml min⁻¹ and 17 ± 1% at 65 ml min⁻¹. The introduction of MPls into soil environments has been noted to modify transport dynamics into soil. As a result, these alterations effects hydrological characteristics of soil, thereby impacting quality of groundwater and agricultural output. The mean absolute error (MAE) of 6% between modeled and observed retention rates suggests minor discrepancies. This study highlights the importance of examining retention efficiency and the accuracy of numerical models in porous media during MPl transport.

Abstract: The venom-containing barb attached to their ‘whip-like’ tail provides stingrays a defensive mechanism for evading predators such as sharks. From human encounters, dermal stingray envenomation is characterized by intense pain often followed by tissue necrosis occurring over several days to several weeks. The bioactive components in stingray venoms (SRV’s) and their molecular targets and mechanisms that mediate these complex responses are not well understood. Given the utility of venom-derived proteins from other venomous species for biomedical and pharmaceutical applications, we set out to characterize the bioactivity of SRV from three local species that belong to the Dasyatoidea ‘whiptail’ superfamily. Multiple cell-based assays were used to quantify and compare the in vitro effects of these SRV’s on different cell lines. All three SRV’s demonstrated concentration-dependent growth inhibitory effects on three different human cell lines tested. In contrast, a mouse fibrosarcoma cell line was markedly resistant to all three SRV’s, indicating the molecular target(s) for mediating the SRV effects are not expressed on these cells. The multifunctional SRV responses were characterized by an acute disruption of cell adhesion leading to apoptosis. These findings aim to guide future investigations of identified SRV proteins and their molecular targets for potential use in biomedical applications.

Weight thresholding (WT) is a method intended to decrease the number of links within weighted networks that may otherwise be excessively dense for network science applications. WT aims to remove links to simplify the networks by holding most of the features of the original network. Here, we test the robustness and the efficacy of the node attack strategies on real-world networks subjected to WT that remove links of higher weight (strong links). We measure the network robustness along node removal with the largest connected component (LCC). We find that the real-world networks under study are generally stable in terms of robustness when subjected to WT. Nonetheless, WT by strong link removal changes the efficacy of the attack strategies and the rank of node centralities. Also, WT by strong link removal may trigger a greater change in node centrality rank than WT by removing weak links. Network science research finding important/influential nodes in the network has to consider that simplifying the network with WT methodologies may change the node centrality.
Mathematics of Epidemics: On the General Solution of SIRVD, SIRV, SIRD and SIR Compartment Models
Authors: Schlickeiser Reinhard , Kröger Martin
Published: March 2024

The susceptible-infected-recovered-vaccinated-deceased (SIRVD) epidemic compartment model extends the SIR model to include the effects of vaccination campaigns and time-dependent fatality rates on epidemic outbreaks. It encompasses the SIR, SIRV, SIRD, and SI models as special cases, with individual time-dependent rates governing transitions between different fractions. We investigate a special class of exact solutions and accurate analytical approximations for the SIRVD and SIRD compartment models. While the SIRVD and SIRD equations pose complex integro-differential equations for the rate of new infections and the fractions as a function of time, a simpler approach considers determining equations for the sum of ratios for given variations. This approach enables us to derive fully exact analytical solutions for the SIRVD and SIRD models. For nonlinear models with a high-dimensional parameter space, such as the SIRVD and SIRD models, analytical solutions, exact or accurately approximative, are of high importance and interest: not only as suitable benchmarks for numerical codes, but especially as they allow us to understand the critical behavior of epidemic outbursts as well as the decisive role of certain parameters. In the second part of our study, we apply a recently developed analytical approximation for the SIR and SIRV models to the more general SIRVD model. This approximation offers accurate analytical expressions for epidemic quantities, such as the rate of new infections and the fraction of infected persons, particularly when the cumulative fraction of infections is small. The distinction between recovered and deceased individuals in the SIRVD model affects the calculation of the death rate, which is proportional to the infected fraction in the SIRVD/SIRD cases but often proportional to the rate of new infections in many SIR models using a posteriori approach. We demonstrate that the temporal dependence of the infected fraction and the rate of new infections differs when considering the effects of vaccinations and when the real-time dependence of fatality and recovery rates diverge. These differences are highlighted for stationary ratios and gradually decreasing fatality rates.

Floods, recognized for their erratic behavior and devastating effects, are a significant threat as a natural disaster. In Brunei Darussalam, the impact of climate change is becoming increasingly evident through higher temperatures and an expected increase in annual rainfall (5.0mm per year from 2021 to 2050), highlighting the critical need for updated flood risk management techniques. In line with the climate resilience and adaptation objectives of WAWASAN 2035, this paper introduces an innovative approach—a cutting-edge flood risk management framework that utilizes the capabilities of big data analytics, sophisticated machine learning algorithms, and smart Internet of Things (IoT) sensors. Traditional methods, which rely on numerical and physical data modeling, often do not provide precise short-term flood forecasts. Our suggested framework uses machine learning to analyze real-time flood forecasting, sensor data and enhance warning systems, addressing the shortcomings of traditional approaches. The key advantage of this approach is its potential to drastically decrease flood-related damages, protect lives, and boost infrastructure resilience. This proposal is not only in aligns with Brunei's vision for a safe and climate-adaptable future but also marks a significant step forward in adopting innovative and sustainable flood risk management solutions amidst an evolving climate.

In patients with schizophrenia, metabolic syndrome is associated with cognitive impairments. We carried out a second analysis of data from a longitudinal trial to examine the relationship between weight gain and cognitive function in patients with first-episode schizophrenia (FES) over the first 6-month antipsychotic treatment. Baseline and 6-month endpoint measurements were taken for both cognitive function and body weight. Linear and logistic regression analyses were applied to investigate the bidirectional relationship between weight gain and cognitive function. Clinically relevant weight gain (CRW) was defined as an increase in body weight ex-ceeding 7%. The final analysis included 337 participants. Lower baseline scores in processing speed (OR=0.837, p=0.007), working memory and attention (OR=0.889, p=0.043), and executive function (OR=0.863, p=0.006) domains were significantly associated with CRW at the 6-month endpoint. After adjusting for confounders, CRW was found to be associated with improvement in the Brief Visuospatial Memory Test (p=0.036). The findings suggest that patients with lower baseline cognitive performance experienced more substantial weight gain. Conversely, weight gain was correlated with cognitive improvements, particularly in the domain of visual learning and memory. This suggested a potential bidirectional relationship between weight gain and cog-nitive function in patients with first-episode schizophrenia.

Elizabethkingia anophelis is an opportunistic pathogen causing lifethreatening infections in humans, particularly in immunocompromised patients, neonates and elderly. Infections caused by this species are exceptionally challenging to treat due to its multiresistance to antimicrobials. We report a case of central line-associated bloodstream infection by E. anophelis in a 2.5-year-old girl with acute lymphoblastic leukemia successfully treated with a combination of piperacillin/tazobactam and amikacin. The literature was also reviewed on paediatric infections caused by E. anophelis. Accurate identification with MALDI-TOF, or using molecular techniques, is crucial because of varying susceptibilities among species. Early, accurate diagnosis and prompt effective treatment optimize outcomes.

Reactive oxygen species (ROS) play a pivotal role in cellular function, and their overproduction contributes to oxidative stress, fatigue, aging, and diseases. To counteract these effects, incorpo-rating antioxidant-rich nutrients is recommended. Functional waters, including electrolyzed hydrogen water (EHW), are gaining attention for potential antioxidant effects through daily in-take. This study employs aquaphotomics and near-infrared spectroscopy (NIRS) to elucidate the molecular mechanisms behind the antioxidant activity of EHW. Previous investigation reported a 100% loss in antioxidant functionality through autoclaving, and a 40% decrease with hydrogen gas removal, prompting the current investigation into the mechanisms of antioxidant effects and especially the role of water molecular structure in it. Aquaphotomics analysis of near infrared (NIR) spectral data revealed that the primary characteristic of EHW associated with anti-radical function is presence of water solvation shells. Autoclaving and degassing led to loss of these water molecular species and a significant increase in free water molecules. The study suggests that water shells (solvation shells) in EHW play a crucial role in neutralizing ROS, although the specific ions or nanoparticles responsible for creating these shells remain unidentified. This concept aligns well with existing proposals of the crucial role of water solvation shells in ROS neutralization.
