While the inundation has affected the daily lives of the residents, showing that there's always room for improvement, it has also highlighted the importance of proactive risk management in dealing with natural disasters. This provides an ideal opportunity to enhance risk management and ensure that similar issues don't arise in the future. This research aims to evaluate the effectiveness of the inundation management strategies implemented by the government and the local community. To achieve this, we are conducting a descriptive study. The collaborative efforts of various public organizations, including the Regency BPBD, Provincial BPBD, Public Works Office of Bina Marga and Water Resources of Sidoarjo Regency, village officials, sub-districts, and Koramil, are a testament to the commitment to tackle this challenge. The community's active involvement is crucial for the success of these efforts. The Bringin Kulon area's comprehensive approach to inundation management includes normalizing water pumps, cleaning water hyacinth and sediment, and installing floodgates. The risk management strategy, though time-consuming, is proving to be highly effective. The community's involvement, though limited, is crucial for the success of these efforts.

Cysteine protease inhibitors (CPIs) have a vital role in the strict regulation and control of cysteine protease activity. In this work, a cysteine protease inhibitor (CPI) from watermelon (Citrullus lanatus) seeds was isolated, purified, and partially characterised. Ammonium sulfate precipitation was used to extract CPI, then size exclusion chromatography and ion exchange were used to further purify it. Papain was used to assess the inhibitory action, and identifying the ideal temperature stability and method of inhibition were part of the biochemical characterisation. The protein content of the fractionated samples ranged from 3.6 to 6.5 mg/L, whereas the crude sample of C. lanatus seed had 9.2 mg/L. Cysteine protease inhibitor (CPI) was isolated from C. lanatus seeds, and the highest inhibitory activity occurred at 60–100% saturation of (NH4)2SO4. The CPI inhibitor exhibits a competitive mode of inhibition on papain, with the same Vmax = 1.06 μmol/min, Km = 2.5 μM, and Ki = 4.00 μM. Its activity is retained up to 65°C, but it drastically decreases beyond 70°C. The work advances knowledge of the biochemical characteristics of CPIs obtained from plants and highlights their applicability in the agricultural and pharmaceutical sectors.

Published: February 2025

Belum ada satu pun undang-undang yang secara khusus mengatur tentang bagaimana mengukur batas-batas apa yang termasuk malpraktik kedokteran dan apa yang tidak termasuk malpraktik kedokteran secara seragam. Tujuan dari penelitian ini yaitu: (1) untuk mengkaji dan menganalisis batasan unsur perbuatan melawan hukum pada dugaan tindak kealpaan medis; (2) Untuk mengkaji dan menganalis kedudukan norma disiplin profesi kedokteran dalam membatasi dugaan tindak pidana kealpaan medis. Jenis penelitian yang digunakan penulis dalam penelitian ini adalah penelitian yuridis normatif. Pengumpulan data yang digunakan penulis dalam penelitian adalah studi dokumentasi dengan pendekatan perundang–undangan (statute approach) dan pendekatan konseptual (conceptual approach). Pembuktian batasan unsur perbuatan melawan hukum pada dugaan tindak kealpaan medis didasarkan atas dipenuhinya tidaknya unsur-unsur tindak pidana tersebut sangat tergantung dari jenis malpraktik yang dituduhkannya. Kedudukan norma disiplin profesi kedokteran dalam membatasi dugaan tindak pidana kealpaan medis dapat tercermin dari Putusan MKDKI sebagai alat bukti untuk pembuktian adanya kelalaian tindakan medik dalam hukum acara pidana dan ratio decidendi sesuai Putusan Mahkamah Konstitusi Nomor 14/PUU-XII/2014. Jika pelanggaran disiplin itu lebih dekat dengan bidang etik, karena menyangkut bidang moral dan pengembangan mental sehingga tidak langsung terkena bidang hukum. Namun untuk menyangkut bidang hukum, masih harus dilihat seberapa jauh dan seberapa berat sifat kelalaian itu. Jika memasuki ranah hukum pidana, maka harus ada kelalaian berat (culpa lata).

CoronaVirus Disease 2019 is a respiratory disease caused by Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) which is transmitted through the air and droplets of fluid. One of the health protocols recommended by the World Health Organization (WHO) is washing hands. Hand-washing activities have limitations because not all places provide them, so the alternative that has been circulating in the community is hand sanitiser. However, the alcohol content and synthetic antibacterials cause dry and irritated skin. The purpose of this study was to create an antibacterial hand cream from putri malu leaf as a utilization of wild plants. Putri malu leaf extract and chitosan were made in the form of nanoparticles, and then an evaluation of the physical characteristics of the hand cream preparation was carried out in the form of pH, organoleptic, homogeneity, and stability observed for 14 days. The antibacterial activity of putri malu leaf extract and hand cream was tested against S. aureus and E. coli. The particle size obtained was 1529.5 ± 42.5 nm. The results of the physical characteristics obtained were pH 6.15; dark orange, odourless, stable at room temperature, and high homogeneity. Antibacterial testing of putri malu leaf extract against S. aureus produced an inhibition zone of 10.27 mm at a concentration of 25% and antibacterial hand cream produced inhibition zones of 23.18 mm and 12.22 mm with an extract concentration of 10% so both are classified as strong antibacterials that are effective against S. aureus and E. coli bacteria.

Published: February 2025

A Síndrome de Guillain-Barré (SGB) é uma polirradiculoneuropatia inflamatória aguda associada a processos infecciosos e, em alguns casos, a imunizações. Com o avanço da vacinação contra a COVID-19, surgiram relatos sobre a possível relação entre a imunização e o desenvolvimento da SGB. Este estudo realizou uma revisão integrativa da literatura para analisar a incidência da SGB em indivíduos vacinados contra a COVID-19. Foram pesquisados artigos publicados entre 2020 e 2024 nas bases EMBASE, Medline/PubMed, Cochrane Library, Science Direct e Scielo, utilizando descritores relacionados à síndrome e à vacinação. Após a aplicação dos critérios de inclusão e exclusão, 16 artigos foram analisados. Os resultados sugerem que algumas vacinas, especialmente as de vetor viral, podem apresentar uma maior associação com o desenvolvimento da SGB, ainda que a relação causal não esteja completamente esclarecida. Estudos epidemiológicos adicionais são necessários para compreender os mecanismos imunológicos envolvidos e garantir a segurança das vacinas.
The Stone Left Unturned: An Assessment of the Impact of Marketisation on the Higher Education Experience of Students with Disabilities
Authors: van der Merwe Leoni
Published: February 2025

The marginalisation of persons with disabilities (PWDs) in South Africa and the world over is not a novel concept; this is evidenced by such persons experiencing poorer health outcomes, higher rates of poverty, economic exclusion, and lower educational achievements. Although general inroads have been made in the realisation of equality in South Africa, the Commission for Employment Equity’s Annual Report for 2021-2022 notes that PWDs comprise 1.2% of the total workforce. Disability is viewed as both the proverbial seed and fruit of poverty and is regarded as a contributory factor to societal exclusion. Higher education institutions (HEIs) play a pivotal role in promoting lifelong learning in addition to the provision of skills, competencies, and expertise to the labour market. In conjunction with various societal stakeholders, HEIs are instrumental in eliminating barriers to entry experienced by students with disabilities (SWDs).
Infusing Decoloniality into the Pedagogy of International Law at South African Tertiary Institutions
Authors: Ncube Swikani , Lenong Jentley
Published: February 2025

The complicity of the regime of international law and the Global North in legally justifying and sustaining colonial projects is patent. Decoloniality – as the new logic and milieu of power composed and comprehended in the aftermath of colonialism – challenges the benevolence of contemporary international law pedagogy. A plethora of research occupies this theme, although the resultant findings have not found their way into the teaching of international law at South African universities. This chapter proposes a framework that informs the necessary pedagogical transformation for the incorporation and teaching of decoloniality in the international law curriculum at tertiary institutions in South Africa.

ТRANSFORMATION OF THE INDIVIDUAL HOUSING CONSTRUCTION MARKET: INTRODUCTION OF ESCROW ACCOUNTS AND CHANGES FAMILY MORTGAGE TERMS
Authors:   Baikal State University, Irkutsk, Shepina Svetlana V.
Published: February 2025

More than half of the construction in the Russian Federation currently accounts for individual housing construction. The popularity of such an option for purchasing real estate has a number of objective and subjective reasons. Traditionally, individual residential buildings were built by small construction contractors or by the future owners themselves.
The adoption in mid-2024 of Federal Law No. 186-FZ "On the construction of residential buildings under construction Contracts using escrow accounts" radically changed the business conditions for construction companies in this market. In addition, the change in the terms of the family mortgage from July 1, 2024, when loans for the construction of private housing under this program can only be obtained for individual construction projects financed through escrow accounts, also gave an additional impetus to qualitative changes in the market.
There is uncertainty about the direction of development of the market for the construction of individual houses in the new financial conditions, as the experience of introducing project financing and escrow accounts for the construction of apartment buildings turned out to be ambiguous.
These circumstances determine the relevance of this study. The article will consider the trends of market development in the new economic conditions. We believe that the introduction of escrow accounts and project financing in the field of individual housing construction will lead to the same changes as in the market for the construction of apartment buildings.

The article considers current issues of teaching French in Russian technical universities. Based on the analysis of France's achievements in science, technology and engi-neering over the past 500 years, the authors conclude that the country has maintained its high intellectual and creative potential to this day. French universities occupy leading positions in the authoritative international rankings QS, THE and ARWU and successfully conduct fundamental research, publishing their results in more than 900 French-language journals indexed in the Scopus scientometric database. To get acquainted with their materials, you need to know spe-cialized French, since modern machine translation systems are not able to adequately convey the content of scientific and technical text. A national network of high-speed railway lines is being created in Russia; in France it has existed since 1981, and is currently the largest in Europe and continues to expand and improve. Knowledge of French is the key to information about innovative developments in this area, which is necessary for the implementation of the Russian project. In the context of a decline in the degree of relations with Western countries, which arose not at Russia's initiative, the vector of Russian foreign policy has reoriented itself towards the countries of the African region, where the French language is widely spoken. This has resulted in the initiation of a number of joint long-term projects in the oil and gas sector (production, transportation, processing, personnel training) with a total value of $500 billion. The scale of the upcoming work increases the relevance of its French language in leading tech-nical universities in Russia.

Authors: Kopylchak O. , Kazymyra I.
Published: February 2025

У цьому дослідженні представлено гібридну модель, яка поєднує колаборативну фільтрацію та глибокі нейронні мережі для підвищення ефективності навчальних рекомендацій. Такий підхід дозволяє оптимізувати процес генерації рекомендацій, забезпечуючи високу гнучкість і точність навіть при обмеженій кількості даних. У випадках, коли наявних даних недостатньо для ефективного навчання нейронної мережі, алгоритм автоматично переходить до використання колаборативної фільтрації, що зберігає якість рекомендацій і стабільність роботи моделі. Результати тестування на наборах даних показали, що гібридна модель підвищує точність і адаптивність рекомендаційної системи порівняно з традиційними методами. Поєднання двох методів дозволяє використати їхні переваги та мінімізувати недоліки, що робить модель універсальною в різних контекстах і з різними обсягами даних. Це особливо актуально у сфері освіти, де дані користувачів можуть бути обмеженими або неповними. Впровадження цієї моделі дає можливість створювати більш ефективні освітні платформи, які забезпечують персоналізоване навчання для широкої аудиторії, враховуючи індивідуальні потреби та вподобання користувачів. Важливою особливістю алгоритму є його здатність адаптуватися до змін у навчальному контенті та налаштовувати рекомендації відповідно до потреб кожного користувача. Це сприяє підвищенню задоволеності користувачів і покращує загальну якість освітніх послуг. Ефективна робота з обмеженими даними підвищує точність і адаптивність системи рекомендацій. Усі ці властивості роблять запропонований алгоритм перспективним інструментом для розвитку персоналізованих освітніх платформ, які краще відповідають індивідуальним потребам. Це сприяє ефективнішому навчанню та кращому засвоєнню матеріалу, що є важливим для розвитку сучасного інформаційного суспільства

Study and Analysis of Students' Representations Regarding the Concept of Cellular Respiration
Authors: Rahioui Fatima , Jouti Mohammed Ali Tahri , El Ghzaoui Mohammed
Published: February 2025

In the discipline of life and earth sciences, so many concepts such as the case of photosynthesis, digestion, blood circulation, and respiration have seen their multidisciplinarity and complexity, which makes it difficult for students to learn them. This problem is aggravated when the initial conceptions of learners are neglected by teachers in their classes. This study aims to study the concept of learning of cellular respiration. To do this, we conducted an epistemological analysis using a written questionnaire highlighting the difficulties encountered by second-year bachelor's students from two fields (life sciences and earth and physical sciences) in mastering this concept. These analyses also allow us to obtain descriptions of the effectiveness of the didactic transposition processes (external and internal) as well as the constraints that create in the construction of scientific knowledge among learners and classify them according to different levels of the didactic codetermination scale. Based on the results, there is no doubt that the teacher has heavy responsibilities both in and outside the classroom. In this work, we emphasize the need to assess the tenacity of the most frequent misconceptions among learners. The use of design inventories seems to be effective for this evaluation to draw up an assessment of the need for training.

Authors: Asubiojo Ojo Raphael
Published: February 2025

In an era characterized by the rapid advancement of educational technology, the role of teachers in ethically and effectively integrating these tools into their teaching practices is crucial. This study examines the intersection of educational technology and ethics, emphasizing the importance of equipping teachers with the knowledge and skills needed to navigate this evolving landscape responsibly. As digital tools become increasingly widespread, educators are confronted with a variety of ethical challenges, including the protection of student privacy and ensuring equitable access to technological resources. This study explores the ethical dilemma teachers’ face when utilizing educational technology and offers strategies for addressing them. The study uses a descriptive research design of the survey type. The population of the study comprises all Basic Science and technology teachers in Ekiti State secondary schools. One hundred and twenty Basic Science and technology teachers were used as sample size which was selected using multi-stage sampling techniques. Three research questions were raised and answered descriptively using simple frequency counts, percentage and mean. Also two corresponding hypotheses were formulated to guide the study. Data for the study were collected using structured questionnaire developed by the researcher and validated by experts in test and measurement and two educational technology experts. The results showed that most teachers of Basic Science and technology were not fully aware of educational technology ethics and therefore possess little or no knowledge in the application of educational technology ethics in their teaching and learning process. Recommendations were made that teachers should undergo professional training in the utilization of educational technology ethics which will promote student achievement, equity and ethical integrity.

La investigación realizada analiza la influencia de las familias en el uso de las Tecnologías de la Información y la Comunicación (TICs) para apoyar el aprendizaje de inglés en estudiantes con Necesidades Educativas Especiales (NEE). Utilizando un enfoque mixto, se combinan datos cuantitativos y cualitativos para comprender las dinámicas familiares y su impacto en el proceso educativo. Los resultados revelaron que la mayoría de las familias brindan un apoyo moderado a sus hijos en el uso de las TIC para el aprendizaje del inglés. Si bien las familias reportan acceso a la tecnología, el docente identifica barreras significativas, destacando la necesidad de un diálogo más efectivo entre la escuela y el hogar. Las TICs se identifican como herramientas clave para motivar y fortalecer habilidades académicas, aunque su uso no siempre es óptimo debido a la falta de formación de los padres y, en ciertos casos, al desinterés de los estudiantes. Los padres han mostrado interés en recibir capacitación, subrayando la importancia de los programas de capacitación que refuercen su rol educativo. Se concluye que el trabajo conjunto entre autoridades, familia, docentes y estudiantes, apoyado por recursos tecnológicos adecuados, es esencial para transformar el aprendizaje y promover el desarrollo integral de los estudiantes con NEE.

La citricultura es relevante en México por la superficie plantada, volumen y valor de la producción, empleos e ingresos que genera en el medio rural. Veracruz es la entidad con mayor volumen de producción de cítricos en el país. El municipio de Gutiérrez Zamora, Veracruz es importante productor citrícola, sin embargo, las unidades minifundistas, con bajos niveles de productividad y precio de la fruta, derivan en escasa capacidad para el sostenimiento de las familias. El objetivo de investigación fue analizar los problemas principales de la citricultura de Gutiérrez Zamora desde la perspectiva de los productores. Para cumplir esto, fue desarrollado un estudio cuantitativo de alcance exploratorio y descriptivo. Se aplicó un cuestionario a 43 citricultores por medio del muestreo no probabilístico de bola de nieve. Los datos colectados se analizaron mediante estadística descriptiva y el apoyo de bibliografía relacionada con el tema. Los diversos problemas expresados por los citricultores están relacionados con la comercialización, cuestiones ambientales, productivas, de organización y de políticas de apoyo. Se concluye que iniciativas de atención a los citricultores deben considerar estrategias de adaptación a las problemáticas ambientales, así como el fortalecimiento de la colaboración familiar y comunitaria.

Dentre as alterações dentárias de tamanho a microdontia ou dentes conoides, são bastante frequentes na clínica odontológica e a busca pela harmonização estética do sorriso através de formas conservadoras e minimamente invasivas, tem ocorrido cada vez mais no dia-a-dia dos consultórios. Atualmente a resolução desses casos com técnicas reabilitadoras minimamente invasivas é possível graças à evolução de técnicas, materiais e protocolos reabilitadores que atuam minimamente sobre a superfície dentária, mantendo-a praticamente hígida. Dessa forma, a estética do sorriso é restabelecida através de procedimentos indiretos conhecidos também por “lentes de contato dentais”. Tais lentes apresentam resultados extremamente satisfatórios e com grande naturalidade. A técnica exige uma correta seleção de caso, verificando quais realmente recebem a indicação para tal reabilitação, associado a um correto planejamento e execução da técnica. Dessa forma, o presente relato de caso apresenta a reabilitação de dentes conóides, que receberam a técnica indireta de lentes de contato, por causarem uma desarmonia ao sorriso pelo tamanho inadequado, mostrando indicações, contra indicações e a técnica de confecçãode laminados cerâmicos de mínima espessura sem desgaste, com resultado altamente satisfatório.

We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses from the Atacama Large Millimeter/submillimeter Array, stellar masses and redshifts from multiband photometry, and JWST/NIRCam rest-frame optical imaging. Using mass-controlled samples, we find an increased fraction of interacting galaxies in the starburst regime at all redshifts out to z = 4. This increase correlates with star formation efficiency (SFE) but not with gas fraction. However, the correlation is weak (and only significant out to z = 2), which could be explained by the short duration of SFE increase during interaction. In addition, we find that isolated disk galaxies make up a significant fraction of the starburst population. The fraction of such galaxies with star-forming clumps (“clumpy disks”) is significantly increased compared to the main-sequence disk population. Furthermore, this fraction directly correlates with SFE. This is direct observational evidence for a long-term increase of SFE maintained due to disk instabilities, contributing to the majority of starburst galaxies in our sample and hence to substantial mass growth in these systems. This result could also be of importance for explaining the growth of the most massive galaxies at z > 6.
Three-dimensional Transport of Solids in a Protoplanetary Disk Containing a Growing Giant Planet

Published: February 2025

We present the results of combined hydrodynamic and particle tracking post-processing modeling to study the transport of small dust in a protoplanetary disk containing an embedded embryo in three dimensions. We use a suite of FARGO3D hydrodynamic simulations of disks containing a planetary embryo varying in mass up to 300 M
⊕ on a fixed orbit in both high- and low-viscosity disks. We then simulate solid particles through the disk as a post-processing step using a Monte Carlo integration, allowing us to track the trajectories of individual particles as they travel throughout the disk. We find that gas advection onto the planet can carry small, well-coupled solids across the gap opened in the disk by the embedded planet for planetary masses above the pebble isolation mass. This mixing between the inner and outer disk can occur in both directions, with solids in the inner disk mixing to the outer disk as well. Additionally, in low-viscosity disks, multiple dust pile-ups in the outer disk may preserve isotopic heterogeneities, possibly providing an outermost tertiary isotopic reservoir. Throughout Jupiter's growth, the extent of mixing between isotopic reservoirs varied depending on dust size, gas turbulence, and the Jovian embryo mass.

Strong emission from doubly ionized oxygen is a beacon for some of the most intensely star-forming galaxies. JWST enables the search for this beacon in the early Universe with unprecedented sensitivity. Using UNCOVER DR1 JWST/NIRCam and Hubble Space Telescope (HST) imaging data of A2744, we identify strong (rest-frame EW >  500Å) [O iii]5008 emitters at z ∼ 7 based on excess F410M flux. We find N = 68 z ∼ 7 [O iii] candidates, including N = 33 with deep HST coverage required to rule out lower-redshift interlopers (13.68 arcmin2 with F814W 5σ depth  >28 AB). Such strong emission lines can produce very red colors often misinterpreted as evidence for old, massive stellar populations, but are shown to be emission lines where we have spectra. Using this deep HST sample, we derive a new [O iii] luminosity function (LF) spanning

. There is little evolution between this LF and published [O iii] LFs at 3 < z < 8, and no evidence of a turnover at faint luminosities. The sizes of these extreme [O iii] emitters are similar to their low redshift counterparts, the Green Peas. The z ∼ 7 [O iii] LF aligns with the Lyα LF at the bright end, suggesting many of these galaxies are also Lyα emitters.
