Published: August 2024

Background: The clinical syndrome of shock, a clinical state characterized by inadequate tissue perfusion, is one of the most dramatic, dynamic and life-threatening problems faced by the physician in the critical care setting.
Methods: This retrospective observational study analysed all critically ill children aged 1 month to 12 years who were admitted to our hospital’s Pediatric Intensive Care Unit (PICU) between January 2023 and December 2023, requiring mechanical ventilation and presenting with clinical evidence of shock. The majority of deaths in this cohort were attributed to decompensated shock. The Paediatric Index of Mortality 3 (PIM3) score was calculated for each patient to evaluate the severity of illness and predict outcomes. The authors meticulously documented the patterns of morbidity and mortality across different types of shock and assessed the outcomes in the PICU. All collected data were systematically compiled and tabulated for comprehensive analysis.
Results: The frequency of shock in our PICU was 2.1% (n=257). However, among mechanically ventilated patients it was present in 104.31 patients. Septic shock was the most commonly encountered shock (62.6%). Out of 186 cases, 125 survived (67.2%), 61 died (32.8%). Shock had no correlation with PIM3 score and mortality.
Conclusions: Shock is a significant cause of morbidity and mortality in children, especially those under 5 years of age. In our study, septic shock was identified as the most prevalent form of shock, with severe pneumonia being the leading cause. We found that mortality rates were higher in patients who required prolonged mechanical ventilation. To improve outcomes and management strategies, larger prospective multicentric studies in developing countries are highly recommended.

Authors: Naznin Tamanna , Monir M. Moniruzzaman , Rahman Mohammad Lutfar , Yeasmin Sabina , Afroj Nayma , Tasnim Asma
Published: August 2024

Background: Melasma, an acquired pigmentary disorder, presents as symmetric, hyperpigmented macules and patches, primarily on the face. Its prevalence ranges from 1.5% to 33.3% and affects women more than men, impacting self-image and quality of life. Genetic predisposition, sun exposure, and hormonal factors significantly increase tyrosinase activity. The study aims to find an association between serum iron profile and melasma among female patients.
Methods: This hospital-based cross-sectional study occurred in the Department of Dermatology and Venereology at Dhaka Medical College Hospital, enrolling 100 women from July 2022 to June 2023. Participants were divided into groups: Group A (patients with melasma) and Group B (healthy respondents without melasma).
Results: The study compared two groups, finding no significant differences in age, marital status, occupation, or income. Group A had a higher percentage of patients with a family history of melasma (70% vs 28%) and significantly lower levels of hemoglobin, serum ferritin, iron, and transferrin saturation, but higher TIBC levels compared to Group B. Melasma was mainly central facial and symmetrical. Group A had a higher frequency of low haemoglobin, ferritin, iron, and transferrin saturation. The mMASI scores showed a negative correlation with hemoglobin, iron, ferritin, and transferrin saturation, and a positive correlation with TIBC, indicating more severe melasma with poorer iron profiles.
Conclusions: There was a significant inverse correlation between low body iron stores and the severity of melasma, indicating that iron deficiency may contribute to or aggravate melasma in females. Therefore, the findings suggest that iron supplementation could improve treatment outcomes for melasma.

How Credible Is the Central Bank of Russia to Russian Households?
Authors: Petrova D. A.
Published: August 2024

The article examines the degree of public trust in the Central Bank of Russia after the transition to inflation targeting. For this purpose, the author analyzes available data from inFOM consumer surveys of confidence in the Bank of Russia as a whole as well as in its inflation targets from 2014 to 2024. Public  confidence  in  the  Bank  of  Russia  remained  relatively  high  from  2014  to  2017  as  inflation targeting was adopted, but the Bank became far less credible to households from 2019 to 2022 because they did not believe the inflation target of 4% was achievable by the end of the current year or over the medium term. This is probably due to their lack of awareness that the Bank’s principal goal is price stability even though they are actually experiencing high inflation. The households surveyed think that government authorities are largely responsible for controlling inflation. Furthermore, consumers do not take notice of the information provided by the Central Bank of Russia. Using news articles from Russian media, posts from news communities on the VKontakte social network, and Google Trends search queries, the author shows that consumers who ignore information about the Bank’s policy are at a serious disadvantage when there is economic uncertainty. The discrepancy between  the  inflation  expectations  of  consumers  and  professional  forecasters  diminishes  as  the volume of information tied to the phrase “Bank of Russia” increases in media, social network posts, and online searches.

China's Impact on Sustainable Economic Growth in Central Asian Countries in the Context of the Silk Road Economic Belt
Authors: Zhang Bin , Nadyrov Sheripzhan , Stepanov Anatoly
Published: August 2024

This paper examines how the economic relations between China and the Central Asian countries affect the economic development of the Central Asian countries in the context of the Belt and Road economy. China has come up with the global economic strategy initiative known as `"`One Belt, One Road" as a way of incorporating and expanding its economic activities around the world into this initiative. The article argues that China's economic activities in Central Asia are part of its global economic strategy. China's global "``Belt and Road Initiative" is aimed at realizing its political aspirations through economic dominance, which then leads to a virtuous cycle. Of course, we all know that every country in the world needs to develop its economy, and Central Asian countries are no exception. Central Asian countries have the need and desire to cooperate with China to develop their own economies, which is the basis of this article.  The method of argumentation in the article is to analyze the development needs and relations of cooperation between the two sides in terms of economic indicators, trade cooperation, economic dependence, infrastructure investment, geopolitical pattern of energy, and transportation of goods of Central Asian countries, respectively, and at the same time, data from World Energy Statistics Yearbook, World Bank, China Statistical Yearbook, and China's Outward Foreign Direct Investment Statistical Bulletin are used as the basis. This provides a clear understanding of the patterns of economic cooperation between China and Central Asian countries, and how they interact with each other. Despite the end of the Cold War and the collapse of the Soviet Union, Central Asia remains a central element of the People's Republic of China's (PRC) security strategy, a strategic location that creates a continuum between China's internal and external security. The guiding principle of China's policy towards Central Asia is primarily stability, which is the main theme of current Chinese politics, with the goal of ensuring continuity from domestic stability to the stabilization of border regions and surrounding areas. Throughout their independent existence, the Central Asian states have had different perceptions of Russia, the United States, China, and European countries, which is one of the prerequisites for the formation of multidirectional foreign policies in Central Asian countries. The balance of interests among Russia, the United States, China, and European countries in the region is of vital importance for Central Asian countries, which ensures the independent foreign policy and development paths of Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan, as well as contributes to the stability of the region.

Authors: Baron Petr , Pivtorak Oleksandr , Ivan Ján
Published: August 2024

The present paper focuses on generating a digital laboratory model at the department by applying the structure from motion technique. The generated digital model is then utilized to create simulation models for application in virtual and augmented reality environments. Nine different approaches to photogrammetric imaging in the laboratory were tested in the experiment. These approaches involved variations in the number of photographs and scanning positions. The results of the experiment were divided into three categories: unsuitable, which required significant modification; incomplete, which required further modification; and suitable, which was directly usable. Some images were unusable due to the similarity of objects in the scene. Experiments showed that some parts of the laboratory were more appropriate to image separately. It was also found that dark and shiny surfaces of objects presented a problem for the computation of the models. Therefore, it was necessary to use markers or colours to eliminate this problem.

Published: August 2024

One of the 21st-century skills that students must possess is critical thinking. An instrument is needed to assess the level of success in developing students' critical thinking abilities. The contribution of this research is the development of numeracy problems based on Education for Sustainable Development (ESD) that can measure students' critical thinking abilities. This research is quantitative, with analysis using Ministep software and involving 75 students as research subjects. Numeracy problems were developed using the 3-D model with the stages of define, design, and develop. The results of this study indicate that the 15 developed numeracy problems are valid as they meet at least one criterion of validity and reliability, with an item reliability value of 0.96. This suggests that the instrument can effectively measure critical thinking skills, cover a diverse range of difficulty levels, and ensure that the formulated questions are suitable for measuring and assessing various student abilities. These results indicate that the ESD-based numeracy problems developed can be used as reference material in similar research or studies related to the analysis of students' critical thinking abilities in solving ESD-based numeracy problems.

Authors: Ong Jia-Xuan , Tong Gee-Kok , Khor Kok-Chin , Haw Su-Cheng
Published: August 2024

In this competitive business world, accurately predicting customer churn is crucial to maintaining and preventing revenue loss. However, due to the imbalanced nature of customer churn data, traditional machine learning algorithms often fail to identify churned customers accurately. This has led to exploring resampling techniques, demonstrating their efficacy in addressing this issue. However, current studies in the customer churn prediction field frequently overlook the untapped potential of comprehensive investigation and comparison of resampling techniques. Instead of exploring and comparing various resampling methods, many studies predominantly rely on a single resampling method, such as SMOTE. Hence, this paper aims to compare and evaluate the effectiveness of several resampling methods, including oversampling, undersampling, and hybrid techniques. We utilized the benchmark dataset, telecommunication customer churn, from IBM Watson, where approximately 26.5% of the customers have churned, indicating that the data is imbalanced. Our results demonstrate that the combination of random forest with a hybrid sampling method – SMOTE-ENN obtained the best result. The combination yields an F1 score of 95.3% and an accuracy of 96.0%, surpassing the studies that utilized the same dataset. This highlights the benefits of comparing resampling techniques in predicting customer churn, specifically in imbalanced datasets.

Authors: E Daou Elie , Özcan Mutlu , Salameh Pascale , Salameh Ziad
Published: August 2024

Objectives: We aimed to evaluate ceramic-alloy interface and emphasize the alteration of alloy microstructure after ceramic layering.
Materials and Methods: Thirty-two discs made from a ceramic-alloy combination of pre-sintered cobalt-chromium (CoCr), cast CoCr, cast nickel-chromium (NiCr), or pre-sintered zirconia were prepared with eight discs in each group. Four specimens were examined as manufactured and four were ceramic-layered. Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-Ray diffractometer (XRD), and an atomic force microscope were used for analysis. Non-layered specimens received ceramic fire-heating without adding any ceramic. Alloy microstructure was compared before and after ceramic veneering or heating within the same group. Mean differences in grain size and surface roughness were compared among groups. P<0.05 was considered significant.
Results: SEM showed a close bonding interface between alloys and ceramics. EDX demonstrated differences compared to the manufacturer’s composition. Ceramic-layering reduced grain size for both milled alloys (P<0.05), whereas grain size increased in cast groups (P=0.011). Heat treatment did the same for the CoCr groups (P=0.013). Ceramic veneering increased the surface roughness of the cast CoCr (Gi) (P=0.029) and NiCr (Wi) (P=0.005) groups, whereas zirconia roughness average (Ra) showed a slight decrease (P=0.282). XRD showed no differences among zirconia, NiCr, and milled CoCr groups before and after veneering. Crystallite size differed between monoclinic and tetragonal phases in zirconia.
Conclusion: The study highlights that ceramic-layering induces significant microstructural changes in alloys, enhancing bonding potential and mechanical stability. Pre-sintered materials show a fine homogeneous surface, optimizing ceramic adherence and potentially improving clinical outcomes.

Climate change represents, today, one of the greatest challenges regarding the availability of water resources for the cultivation of food and raw materials of plant origin that the world's population so badly needs. Sugarcane, due to its high added value to produce several products and whose accumulation of sucrose is mainly due to a perfect dosage of water, brought to light the need to obtain new irrigation strategies, thus aiming at a more sustainable, efficient and economical management of water consumption in this sector. As an alternative to this challenge, drip irrigation stood out, which allowed not only a more precise control of water dosage, but also essential nutrients for the development of sugarcane. Taking advantage of this, a sugar and alcohol plant in the interior of the state of São Paulo, whose identity will be preserved, made several investments to implement this system on its farms and one of these projects will be discussed in detail about the dimensioning of the entire piping network. which involves the pumping system, from water collection to discharge into a storage tank, responsible for supplying the dripping, using a pre-dimensioned pump and respecting the specifications defined by the client for this work. In addition, the free software Scilab was used to implement the piping and pumping sizing procedure, as an extra tool, in addition to development in Excel.

Published: August 2024

Cigarette butts are a significant environmental issue, mainly when they are improperly discarded. However, this waste type is recyclable, since its structure is based on cellulose acetate, which is used in the industrial sector for absorbent and filtering purposes. The aim of the present study is to chemically change cellulose acetate deriving from cigarette filters by incorporating iron to it, in order to use it as catalyst in effluent treatment processes. Three different methods were used for iron immobilization purposes in basic, acidic and ferric media, for 7 days. The method showing the best iron adsorption, based on spectroscopic analyses, was the one wherein cigarette butts remained in contact with 0.1 mol/L ferric solution. Therefore, the group of cigarette butts resulting from this method was used in Fenton and photo-Fenton processes. Moreover, it recorded positive results for textile dye mix discoloration, as evidenced by spectral changes in the 350-700 nm range, which pointed out significant color change in the assessed sample. Although the current article results from a preliminary study, the herein collected data point towards the potential use of cigarette butts as alternative to treat effluents deriving from companies that use large amounts of dye.

Published: August 2024

Anafilaksja to stan zagrażający życiu, charakteryzujący się szybkim przebiegiem i wymagający natychmiastowej interwencji. Zachodzi zarówno w mechanizmie immunologicznym, jak i nieimmunologicznym. Wywoływana jest przez różnorodne czynniki, takie jak pokarmy, leki czy jady owadów. Spektrum objawów jest bardzo szerokie; najczęściej obserwuje się objawy skórne, ze strony układu oddechowego oraz pokarmowego. Diagnostyka opiera się na kryteriach klinicznych, a głównym elementem leczenia jest domięśniowe podanie adrenaliny. Prewencja polega na unikaniu wyzwalaczy, a gdy nie jest to możliwe, należy rozważyć przeprowadzenie desensytyzacji. Zgony spowodowane wstrząsem anafilaktycznym są rzadkie i często wynikają z opóźnionej lub niewłaściwej pomocy medycznej oraz braku świadków, którzy mogliby wezwać pomoc. Szacuje się, że około 1% przypadków wstrząsu anafilaktycznego kończy się zgonem. Rzadko dochodzi do zgonu w wyniku samobójczych prób poprzez celowe wywołanie reakcji anafilaktycznej. Diagnostyka pośmiertna stanowi wyzwanie ze względu na brak specyficznych zmian, dlatego należy dokładnie ocenić okoliczności zgonu, historię medyczną oraz wykluczyć inne potencjalne przyczyny. Istotne jest zidentyfikowanie czynników mogących wywołać reakcję anafilaktyczną, takich jak spożyte pokarmy czy kontakt z alergenami. Kluczowa jest szybka i dokładna diagnostyka w celu uniknięcia błędów wynikających z procesów rozkładu ciała po śmierci. Badania histopatologiczne oraz oznaczenie markerów biochemicznych, takich jak poziomy tryptazy i IgE, mogą być pomocne w ustaleniu przyczyny zgonu.

Foram analisados documentos curriculares no período de 2016 a 2021 e registros produzidos pela coordenação pedagógica e professores nos Horários de Trabalho Pedagógico Coletivo (HTPC) de uma escola de Educação Infantil localizada em uma cidade do interior de São Paulo. Para tal, utilizou-se a metodologia da pesquisa bibliográfica e documental pautada no referencial teórico de Laurence Bardin, seguindo as etapas de pré-análise, tratamento dos resultados, inferência e interpretação. A partir dos indícios deixados nos registros, foi possível concluir que, apesar do período de suspensão do atendimento presencial por consequência da disseminação do vírus SARS-CoV-2, responsável por ocasionar a pandemia de COVID-19, o currículo foi ressignificado e adaptado às adversidades apresentadas em um momento de crise.
Popular Modernisms: Art, Cartoons, Comics and Cultural In/Subordination
Authors: Barber Bruce
Published: August 2024

Popular Modernisms offers a practical explication to the symbolic contest of cultural power, as this is representative of the struggle between various groups and constituencies over the social meanings and cultural relevance, or lack thereof, of modern(ist) art. I have demonstrated how the “shock of the new” represented in the various activist and antagonist projects of the modernist and post-modernist avant-gardes, have resulted in various socio-cultural responses; that humour in the form of parodies, graphic satires, pastiches, grotesques, lampoons, and burlesques of the products and ideas of high culture—produced by those outside of the production and reception sites of cultural dominance—has served the interests both of tension management and social critique.

Learning in the 4.0 revolution era requires teaching staff to prepare innovative and creative learning models and methods according to students' needs. To meet these needs, the role of technology is needed in its implementation. An online learning system via LMS is the right solution for today's students. To foster collaboration between students and increase learning activities, a project-based learning model was chosen. Teaching materials were developed using Dick and Carey's development design through several stages leading to formative evaluation. The resulting product is then implemented in large lecture classes. The results of the implementation show that there has been an increase in student learning activities when implementing this learning. The percentages of each activity in sequence are giving consideration activities reaching 95.15%, training activities reaching 91.21%, interpreting activities reaching 71.96%, applying activities reaching 68.30%, evaluating activities reaching 66.18%, and creative activity reached 51.24%. The results of student learning activities show a tendency for students' thinking structures from easy things to difficult things.

Aproximación a las potencialidades de una gobernanza para la paz en el contexto del posacuerdo
Authors: Arias Campos Rosa Ludy
Published: August 2024

La situación que experimenta Colombia después de la firma del acuerdo de paz entre las farc-ep y el Estado colombiano, se caracteriza por la confluencia de diversas situaciones que, al tiempo que obstaculizan su implementación, retrasan las medidas de carácter integral para la construcción de una paz estable y duradera. Con este panorama, se mezclan procesos como la manipulación de la información sobre los alcances de los acuerdos, el poco apoyo del Gobierno, la polarización de la opinión pública, el fortalecimiento de los grupos armados ilegales en los territorios y el asesinato de líderes y excombatientes, al tiempo que se mantienen expresiones de compromiso on la paz por parte de las organizaciones sociales, algunos partidos políticos, la academia y la cooperación internacional.
Un extraño despertar: balance de la gobernanza en Suramérica por las revueltas del 2019
Authors: Castañeda Lozano Yebrail
Published: August 2024

El estallido social del 2019 en todo el mundo muestra la insatisfacción y el desencanto de la población debido a la mala gestión de los gobiernos de turno. De manera particular, se investigó el caso de los países suramericanos y se mostró que, debido a los prolongados gobiernos de derecha e izquierda, se generaron los fenómenos políticos como la manipulación, el populismo, la corrupción y la polarización, con el trasfondo histórico de las desigualdades sociales de las poblaciones. Las comunidades no se sienten representadas por los gobiernos y hay “un extraño despertar” que exige políticas participativas, consensuadas y conmensurables. La carencia de una gobernanza transparente y participativa por parte de los dirigentes de las ramas del poder público profundiza los problemas económicos y políticos en toda la región, con prácticas clientelistas, abusos de poder y de corrupción. La buena gobernanza propicia el respecto por los poderes, por las instituciones y por los organismos estatales.

Ephemeral gully and rill erosion have significant effects on agricultural land around the world. The characterization and quantification of these phenomena require us to determine their geometry and evolution, through either 3D or 2D approaches. 3D techniques are able to cover large areas at the expense of accuracy in their measurements, while 2D techniques are more accurate but can only be utilized on small areas at plot scale. This chapter highlights the current state of the art of ephemeral gully/rill measurement techniques based on the characterization of channel cross-sections. Gully/rill erosion is characterized and channel volume measuring techniques are described. Factors contributing to measurement error are explored, including (i) resolution of cross-section elevation profiles, (ii) channel size and shape, and (iii) number of cross-sections used per unit channel length. The case study indicates that the authors’ approach accurately determines the cross-section geometry of small erosion channels.
Advances in tracking sediment transport from agricultural land
Authors:   University of Sheffield, UK, Parsons Anthony
Published: August 2024

The distance particles are transported is important because (i) is necessary for reconciling measurements of erosion made at different scales; (ii) it impacts on travel times of pollutants that adhere to eroded soil particles; and (iii) it is important for identifying sources of pollutants in waterways. Tracking soil particles is difficult because of their size, typically well under 2mm. This chapter reviews bulk tracking of sediment movement and tracking of individual particles. Most studies are small-scale and further work is needed to implement their findings to erosion from agricultural land, in combination with models that explicitly consider transport distance.
EKONOMI KERAKYATAN BERBASIS POTENSI LOKAL
Authors: Hasmawati Fifi
Published: August 2024

Ekonomi kerakyatan dapat dikatakan suatu sistim yang berbasis pada kekuatan ekonomi rakyat. Karena  ekonomi kerakyatan sendiri merupakan  kegiatan perekonomi atau usaha yang dilakukan oleh rakyat kebanyakan  yang secara swadaya mengelola sumberdaya ekonomi yang mampu diusahakan dan kuasainya, mereka mengharapkan bisa terpenuhi kebutuhan dasar keluarga dan tidak mengganggu kepentingan masyakarat sekelilingnya. Hal ini sering kita dengar dengan disebutkan  Usaha Kecil dan Menengah (UKM). Konsep ekonomi kerakyatan dikembangkan sebagai usaha untuk lebih mengedepankan masyarakat untuk membangun kesejahteraandengan pemberdayaan masyarakat. Kemakmuran masyarakatlah yang diutamakan bukan kemakmuran orang perorang. Sebab itu perekonomian disusun sebagai usaha bersama berdasarkan atas asas kekeluargaan. Tujuan utama penyelenggaran dari sistim ekonomi kerakyatan adalah mewujudkan keadilan sosial bagi seluruh rakyat Indonesia melalui peningkatan kemmpuan masyarakat dalam mengendalikan jalannya roda perekonomian. Hal ini mampu menjangkau sasaran pokok  ekonomi kerakyatan yaitu tersedianya peluang kerja dan penghiduan yang layak, sistim jaminan sosial bagi fakir miskin dan anak telantar, distribusi kepemilikan modal yang material relatif merata, pendidikan nasioanal secara cuma-cuma, dan kebebasan masyakat dalam mendirikan sektor ekonomi ataupun menjadi anggota serikat ekonomi.
