Published: July 2023

The city of Douala in Cameroon is facing great challenges in terms of its demographic growth, economic development and urbanization, especially in relation to environmental and economic factors. However, there has been significant growth in its road transport sector, which has led to an excessive demand for the consumption of fossil fuels and an increase in greenhouse gas emissions in recent decades within this sector. However, no concrete policy has yet been put in place to improve the energy efficiency of the transport sector. This work aims to identify the driving factors and determine their contributions to the variation in energy consumption. In this study, a decomposition analysis via the Logarithmic Mean Divisia Index (LMDI) method is used for the period of 2010–2019 to quantify the respective effects of the driving factors on the variation in energy consumption. Based on the study of the literature, we classified four main driving factors in the road transport sector that contributes to the total variation in energy consumption, such as vehicle energy intensity, vehicle intensity, gross domestic product (GDP) by capita, and population scale, with each contributing 13.06%, 31.30%, 12.85%, and 42.76%, respectively. In particular, we note that the energy intensity coefficient of the vehicles from 2013 to 2016 and that of the intensity of the vehicles coefficient from 2010 to 2011 and 2012 to 2013 are the two factors that have, nevertheless, led to a slight decrease in the variation in energy consumption. This implies that an improvement in these two factors would contribute to enhancing the energy efficiency of the road transport sector of the city of Douala. It will therefore be necessary to put in place several energy-saving strategies that would lead to a rationalization of energy consumption in order to reduce greenhouse gas emissions by road transports. Policymakers should take this study into account to achieve a balance between energy consumption and economic growth to better integrate the notion of sustainable road transport.

Published: July 2023

As primary components of solar power applications, photovoltaic cells have promising development prospects. Due to the characteristics of PV cells, the identification of parameters for circuit models has become a research focus. Among the various methods of parameter estimations, metaheuristic algorithms have attracted significant interest. In this paper, a hybrid-strategy-improved dragonfly algorithm (HIDA) is proposed to meet the demand for high parameter-identification accuracy. Tent chaotic mapping generates the initial position of individual dragonflies and aids in increasing the population diversity. Individual dragonflies can adapt their updated positions to various scenarios using the adjacent position decision approach. The whale optimization algorithm fusion strategy incorporates the spiral bubble-net attack mechanism into the dragonfly algorithm to improve the optimization-seeking precision. Moreover, the optimal position perturbation strategy reduces the frequency of the HIDA falling into local optima from the perspective of an optimal solution. The effectiveness of the HIDA was evaluated using function test experiments and engineering application experiments. Seven unimodal and five multimodal benchmark test functions in 50, 120, and 200 dimensions were used for the function test experiments, while five CEC2013 functions and seven CEC2014 functions were also selected for the experiments. In the engineering application experiments, the HIDA was applied to the single-diode model (SDM), engineering model, double-diode model (DDM), triple-diode model (TDM), and STM-40/36 parameter identification, as well as to the solution of seven classical engineering problems. The experimental results all verify the good performance of the HIDA with high stability, a wide application range, and high accuracy.

Published: July 2023

The initial and vital stage in the diagnosis of malaria involves extracting DNA. The efficiency of malaria testing is restricted by the multiple steps involved in commercial DNA extraction kits. We attempted to improve an existing loop-mediated isothermal amplification (LAMP) for the detection of Plasmodium knowlesi by using a simple DNA extraction approach, making it a feasible option for mass screening. We utilized a simple nucleic acid extraction method directly from whole blood for the detection of P. knowlesi, taking only 5 min to complete. The extracted DNA was evaluated by two fluorescent-based LAMP and one colorimetric-based LAMP assay. The detection limit for both SYTO-LAMP and SYBR green-LAMP was 0.00001% and 0.0001% parasitemia, respectively. Meanwhile, neutral red-LAMP had a detection limit of 0.01% parasitemia. Combining this simple and inexpensive DNA extraction method, SYTO-LAMP could serve as an alternative molecular diagnosis for the detection of P. knowlesi and other human Plasmodium spp.

From the beginning of public vaccinations until the relaxation of COVID-19 measures, many case reports, case series and case–control studies have been published indicating cutaneous side effects of COVID-19 vaccination. Post-vaccination pustular eruption was reported as well, with a challenging differential diagnosis between pustular psoriasis, AGEP (acute generalized exanthematous pustulosis) and neutrophil pustular eruptions. We report a case of 56-year-old woman presented with acute generalized pustular flare up culminated 5 days after the second dose of BNT162b2(Pfizer) vaccination. She was diagnosed with pustular psoriasis flare and due to the regulating role of IL-1 in pustular psoriasis and in the cytokine storm observed in cases of COVID-19 postvaccination inflammation; we decided to treat the patient with an IL-1 antagonist, subcutaneous anakinra (100 mg daily) along with acitretin. One week later, after anakinra withdrawal, she presented a pustular psoriasis flare and a 7-day anakinra re-administration led to a satisfactory improvement in the skin lesions. We also reviewed the medical literature and found 28 case reports with pustular eruption after the COVID-19 vaccination. We compared the patients reported, regarding sex, age, number of doses, post-vaccination period and vaccine brand, and compared those results with our patient. Finally, as indicated by our case and other cases with similarly treated pustular eruptions. targeted therapy to this cytokine imbalance such as anakinra (IL-1) antagonist can improve the clinical course of the patient.

Published: July 2023

Rotavirus is an important cause of fatal pediatric diarrhea worldwide. Many national immunization programs began adding rotavirus vaccine following a 2009 World Health Organization recommendation. Kenya added rotavirus vaccine to their immunization program at the end of 2014. From a cohort of 38,463 children in the Kisumu health and demographic surveillance site in western Kenya, we assessed how the implementation of the rotavirus vaccine affected mortality in children under 3 years of age. Following its introduction in late 2014, the span of rotavirus vaccine coverage for children increased to 75% by 2017. Receiving the rotavirus vaccine was associated with a 44% reduction in all-cause child mortality (95% confidence interval = 28–68%, p < 0.0001), but not diarrhea-specific mortality (p = 0.401). All-cause child mortality declined 2% per month following the implementation of the rotavirus vaccine (p = 0.002) among both vaccinated and unvaccinated children, but diarrhea-specific mortality was not associated with the implementation of the rotavirus vaccine independent of individual vaccine status (p = 0.125). The incidence of acute diarrhea decreased over the study period, and the introduction of the rotavirus vaccine was not associated with population-wide trends (p = 0.452). The receipt of the rotavirus vaccine was associated with a 34% reduction in the incidence of diarrhea (95% confidence interval = 24–43% reduction). These results suggest that rotavirus vaccine may have had an impact on all-cause child mortality. The analyses of diarrhea-specific mortality were limited by relatively few deaths (n = 57), as others have found a strong reduction in diarrhea-specific mortality. Selection bias may have played a part in these results—children receiving rotavirus vaccine were more likely to be fully immunized than children not receiving the rotavirus vaccine.

Published: July 2023

Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), is a prevalent global infectious disease and a leading cause of mortality worldwide. Currently, the only available vaccine for TB prevention is Bacillus Calmette–Guérin (BCG). However, BCG demonstrates limited efficacy, particularly in adults. Efforts to develop effective TB vaccines have been ongoing for nearly a century. In this review, we have examined the current obstacles in TB vaccine research and emphasized the significance of understanding the interaction mechanism between MTB and hosts in order to provide new avenues for research and establish a solid foundation for the development of novel vaccines. We have also assessed various TB vaccine candidates, including inactivated vaccines, attenuated live vaccines, subunit vaccines, viral vector vaccines, DNA vaccines, and the emerging mRNA vaccines as well as virus-like particle (VLP)-based vaccines, which are currently in preclinical stages or clinical trials. Furthermore, we have discussed the challenges and opportunities associated with developing different types of TB vaccines and outlined future directions for TB vaccine research, aiming to expedite the development of effective vaccines. This comprehensive review offers a summary of the progress made in the field of novel TB vaccines.

Reducing the stigma and discrimination faced by men who have sex with men (MSM) and transgender women (TGW) in healthcare settings is key to improving health outcomes. Using a one-group pre- and post-test design, we tested the efficacy of a theory-informed, multi-level pilot intervention (“Harmony”) among 98 healthcare workers (HCWs) to reduce sexual orientation and gender identity (SOGI)-related stigma and discrimination faced by MSM and TGW in two public hospitals. The intervention contained group-level (a half-day workshop) and individual-level (four videos) components. Using multi-level modelling, we compared knowledge, attitudes, and comfort level among HCWs across three timepoints: pre-intervention, post-intervention, and follow-up (2 months after the intervention). Client surveys were conducted among 400 MSM/TGW (two independent samples of 200 MSM/TGW) attending the intervention hospitals, before the intervention among HCWs and three months after the intervention. Generalised estimating equations assessed service users’ satisfaction with hospital services, discrimination experiences, and positive interactions with HCWs. Significant changes were observed in primary outcomes: 30% increase in positive attitude scores (incidence rate ratio (IRR) = 1.30, 95% CI 1.13–1.49) and 23% increase in the proportion of HCWs reporting being comfortable in providing care to MSM/TGW (IRR = 1.23, 95% CI 0.03–1.68). Similarly, there was a significant improvement in secondary outcomes (scores): support for non-discriminatory hospital policies (IRR = 1.08, 95% CI 1.004–1.15), the importance of asking SOGI questions in clinical history (IRR = 1.17, 95% CI 1.06–1.29), and perceived self-efficacy in providing clinical care (IRR = 1.13, 95% CI 1.01–1.27). Service users’ data provided corroborative evidence for intervention efficacy: e.g., 14% increase in the proportion of MSM reporting overall satisfaction with hospital services and 6% and 15% increase in the scores of positive interactions with HCWs in the combined sample of MSM/TGW and TGW, respectively. The Harmony intervention showed preliminary evidence for improving positive attitudes, comfort level, and understanding of the healthcare issues of MSM/TGW among HCWs, warranting large-scale implementation research.
VSG Control for Cascaded Three-Phase Bridge Based Battery Inverter
Authors: Qi Xiaojing , Zheng Jianyong
Published: July 2023

With the increasing number of new energy sources connected to the grid, the unbalanced output of three-phase grid-connected inverters and the lack of no inertia and damping characteristics in the traditional microgrid control system will seriously affect the stability of voltage, frequency, and power angle for microgrids. This paper proposes a novel cascaded three-phase bridge inverter topology for the battery system used for the electric vehicle. Compared with traditional cascaded H-bridge inverters, the proposed multilevel inverter can achieve self-adaptive balance for three phases. The mathematical model of a cascaded three-phase bridge inverter is established in this paper. Based on the voltage and current equations of a multilevel inverter, a new modulation strategy named carrier phase-shifted-distributed pulse width modulation (CPSD-PWM) was developed, which is more suitable for cascaded three-phase bridge inverters. The harmonic analytic equations of carrier phase-shifted pulse width modulation (CPS-PWM) and CPSD-PWM are constructed by the double Fourier analysis method. Compared with the traditional PWM modulation strategy, the CPSD-PWM can reduce the output harmonics and improve the balance of the three-phase output, which can realize the three-phase adaptive balance in the cascaded three-phase bridge inverter. This paper develops a cascaded three-phase bridge multilevel power converter system based on the virtual synchronous generator (VSG) control strategy. The voltage and frequency of inverter output can be accurately controlled in both island mode and grid-connected mode through active power-frequency regulation and reactive power–voltage regulation, and the stability of primary frequency regulation for the multilevel microgrid inverter can be improved by collaborative optimization of virtual inertia and virtual damping. The CPSD-PWM modulation strategy and VSG control strategy are verified by the simulation results and experimental data for the cascaded three-phase bridge inverter.

New estimates related with the best polynomial approximation
Authors: Bustamante Jorge
Published: July 2023

In some old results, we find estimates the best approximation \(E_{n,p}(f)\) of a periodic function satisfying \(f^{(r)}\in\mathbb{L}^p_{2\pi}\) in terms of the norm of \(f^{(r)}\) (Favard inequality). In this work, we look for a similar result under the weaker assumption \(f^{(r)}\in \mathbb{L}^q_{2\pi}\), with \(1<q<p<\infty\). We will present inequalities of the form \(E_{n,p}(f)\leq C(n)\Vert D^{(r)}f\Vert_q\), where \(D^{(r)}\) is a differential operator. We also study the same problem in spaces of non-periodic functions with a Jacobi weight.

Background: Colorectal cancer (CRC) is the third most common cancer in Iran, where there is no organised CRC-screening programme. This study aimed to evaluate feasibility of CRC screening using a qualitative fecal immunochemical test (FIT) among Iranian average-risk adults. Methods: In this feasibility study, 7039 individuals aged 50–75 years were invited by community health workers (CHWs) in southern Tehran and its suburban districts between April 2018 and November 2019. The CHWs performed a qualitative FIT with cut-off level 50 ng Hb/mL buffer and referred those with positive-FIT for colonoscopy to the endoscopy center of Shariati hospital in Tehran. Outcomes included acceptance rate, FIT positivity rate, colonoscopy compliance, detection rates and positive predictive values (PPVs) with 95% confidence interval for CRC and advanced adenomas (AAs). Results: Acceptance rate at initial invitation was 71.7%. From 4974 average-risk adults (1600 males and 3374 females) who were offered FIT, 96.8% (n=4813) provided valid samples, of whom 471 (9.8%) tested positive. Among FIT-positive participants, 150 (31.8%) underwent colonoscopy; CRC was detected in 2.0% (n=3) and adenomas in 27.3% (n=41). Detection rate of CRC and AAs per 1000-FIT-screened participants was 0.6 (0.1–1.8) [males: 0.7 (0.01–3.6), females: 0.6 (0.07–2.0)] and 4.2 (2.5–6.4) [males: 5.9 (2.6–11.0), females: 3.4 (1.7–6.0)], respectively. PPVs were 2.0% (0.4–5.7) for CRC and 13.3% (8.3–19.8) for AAs. There was no association between gender and the studied outcomes. Conclusion: Our results partially support the feasibility of scaling up organized CRC-screening through the existing healthcare system in Iran; it remains to be discussed carefully to ensure the capacity of healthcare system for adequate colonoscopy services.

Background: COVID-19 infection and its neurological manifestations were seen in children although less common than adults. The aim of this study was to determine the frequency of different types of neurologic findings of hospitalized children with COVID-19. ] Methods: This retrospective study was performed on hospitalized pediatric patients aged≤18 years with confirmed SARS-CoV-2 at Children’s Medical Center Hospital. Neurological manifestations were defined as the presence of any of the following symptoms: seizure, altered mental status, behavioral/personality change, ataxia, stroke, muscle weakness, smell and taste dysfunctions, and focal neurological disorders. Results: Fifty-four children with COVID-19 were admitted and their mean age was 6.94±4.06 years. Thirty-four of them (63%) were male. The most frequent neurological manifestation was seizure (19 [45%]) followed by muscle weakness (11 [26%]), loss of consciousness (10 [23%]), and focal neurological disorders (10 [23%]). Other neurological manifestations consisted of headache (n=7), movement disorders (n=6), behavioral/personality change (n=5), ataxia (n=3), and stroke (n=3). Twenty-nine percent of our patients had leukocytosis. A neutrophil count above 70% was seen in 31% of participants. Among our patients, 81% had a positive reverse-transcription polymerase chain reaction (RT-PCR) test for SARS-CoV-2. Conclusion: During the current pandemic outbreak, hospitalized children with COVID-19 should be evaluated for neurological signs because it is common among them and should not be under-estimated.

Published: July 2023

Inflammatory bowel disease (IBD) is associated with body composition changes, which are associated with clinical prognosis, response to therapy, and quality of life in IBD patients. Therefore, it is critical to review the body composition distribution in IBD, summarize the potential factors affecting body composition distribution, and take steps to improve the body composition distribution of IBD patients as early as possible. In the current review, we searched PubMed via keywords ‘inflammatory bowel disease’, or ‘IBD’, or ‘Crohn’s disease’, or ‘CD’, or ‘ulcerative colitis’, or ‘UC’, and ‘body composition’. Malnutrition and sarcopenia are common in IBD patients and are associated with the clinical course, prognosis, and need for surgery. Disease activity, reduced nutrition intake, vitamin D deficiency, and intestinal dysbiosis are factors contributing to changed body composition. Early use of biological agents to induce remission is critical to improving body composition distribution in IBD patients, supplementation of vitamin D is also important, and moderate physical activity is recommended in IBD patients with clinical remission.

Genetic analysis of non-syndromic hearing loss (NSHL) has been challenged due to marked clinical and genetic heterogeneity. Today, advanced next-generation sequencing (NGS) technologies, such as exome sequencing (ES), have drastically increased the efficacy of gene identification in heterogeneous Mendelian disorders. Here, we present the utility of ES and re-evaluate the phenotypic data for identifying candidate causal variants for previously unexplained progressive moderate to severe NSHL in an extended Iranian family. Using this method, we identified a known heterozygous nonsense variant in exon 26 of the DIAPH1 gene (MIM: 602121), which led to "Deafness, autosomal dominant 1, with or without thrombocytopenia; DFNA1" (MIM: 124900) in this large family in the absence of GJB2 disease-causing variants and also OtoSCOPE-negative results. To the best of our knowledge, this nonsense variant (NM_001079812.3):c.3610C>T (p.Arg1204Ter) is the first report of the DIAPH1 gene variant for autosomal dominant non-syndromic hearing loss (ADNSHL) in Iran.

Circulación de imágenes de animales híbridos entre Mesopotamia y el norte de África en el IV milenio a.C.
Authors: Maydana Sebastián
Published: July 2023

La reciente reedición de un libro de David Wengrow dedicado a los “monstruos” en el arte egipcio y mesopotámico del IV milenio a.C. supone una excusa perfecta para discutir el rol de las imágenes en la historia, en las sociedades humanas y en sus interrelaciones. Mientras que su teoría, cognitivista, considera a las imágenes de animales fantásticos apenas como mecanismos de traducción del mundo circundante, otros académicos (entre los que me incluyo) le otorgan al arte y a la imaginación un papel activo en la creación de dicho mundo. En esta oportunidad me gustaría demostrar la utilidad del segundo abordaje para comprender la historia antigua de sociedades con tradición iconográfica antes que escrita. Para ello, discutiré el modelo cognitivista de “transmisión” de este tipo de imágenes impugnando la centralidad que es asignada a las ciudades, y privilegiando en cambio los espacios inter-urbanos como verdaderos ámbitos para el intercambio icónico. Pensar la imagen no como un emblema transmisor de significados, sino como un instrumento para influir sobre el paisaje y modificar lo existente, permite entender mejor las dinámicas de relacionamiento entre diferentes unidades políticas en el pasado a través de la utilización de iconografías compartidas.
La dimensión imperial y atisbos de africanidad para pensar las independencias africanas
Authors: De Altube Ramiro
Published: July 2023

Una imagen instantánea de Ghana en 2022, como ejemplo de las repúblicas africanas actuales, nos muestra la singularidad de su recorrido, dificultades para la consolidación del Estado-nación y la soberanía conseguida hace décadas, además de algunos elementos complejos cuya comprensión puede ser modificada si cambiamos parcialmente la perspectiva, incorporamos la dimensión imperial e inscribimos el proceso de las independencias políticas formales en una mirada de larga duración. Eso implica pensar la historia de los modos de producción de otra manera y destacar los elementos de continuidad neocolonial. Este enfoque quizás ayude a entender los trazos de la narrativa común de los líderes independentistas que insiste en la africanidad y los valores propiamente africanos como forma de resistencia cultural y fundamento del futuro que estaban ayudando a construir.

Küresel ölçekli hızlı değişim ve dönüşüm, artan çevresel belirsizlikler, iklim krizi, ekolojik dengede meydana gelen bozulmalar, örgütlerin sürdürülebilirlik performansını olumsuz yönde etkilemektedir. Çevresel belirsizliklerin olduğu bu yeni düzende firmaların sürdürülebilirliği sağlayabilmelerinde; yeşil yenilik faaliyetlerinde bulunmaları, çevreci davranışlar göstermeleri ve dayanıklı olmaları önem kazanmaktadır. Bu çalışmanın temel amacı, örgütsel dayanıklılık kapasitesi, yeşil yenilik, algılanan yeşil örgütsel davranış, çevresel belirsizlik ve sürdürülebilirlik performansı arasındaki ilişkilerin incelenmesidir. Araştırma 2020 yılı Türkiye’nin 500 Büyük Sanayi Kuruluşu (İSO 500 ve İSO İkinci 500) listesinde yer alan firmalarda çalışan yöneticilerin katılımıyla ve anket yöntemiyle gerçekleştirilmiştir. Nihai örneklem 430 yöneticiyi içermektedir. Verilerin analizinde SPSS 26 ve AMOS 24 yazılım programları kullanılmıştır. Araştırma ile örgütsel dayanıklılık kapasitesinin yeşil yeniliği, algılanan yeşil örgütsel davranışın yeşil yeniliği, yeşil yeniliğin sürdürülebilirlik performansını, örgütsel dayanıklılık kapasitesinin sürdürülebilirlik performansını ve algılanan yeşil örgütsel davranışın sürdürülebilirlik performansını pozitif etkilediği tespit edilmiştir. Çevresel belirsizliğin, yeşil yenilik ile sürdürülebilirlik performansı arasındaki ilişkide moderatör etkisinin bulunduğu, örgütsel dayanıklılık kapasitesi ile yeşil yenilik arasındaki ilişkide ise moderatör etkisinin bulunmadığı saptanmıştır. Araştırma sonuçları dikkate alındığında, örgütlerin dayanıklılıkları, sürdürülebilirlik ve yeşil odaklı politikalara sahip olmaları onların varlıklarını devam ettirebilmelerinin yanı sıra gezegenin makro boyuttaki sorunları aşabilmesi ve gelecek kuşaklara yaşanabilir bir dünya için de kilit bir rol oynamaktadır.
EĞİTİM HARCAMALARI İLE CİNSİYETE GÖRE GENÇ İŞSİZLİK İLİŞKİSİ: TÜRKİYE ÖRNEĞİ

Eğitim bireylere yönelik olmasına rağmen toplumu etkileyen bir olgudur. Eğitimli bireyler eğitimli toplumları; eğitimli toplumlar ise gelişim ve değişimi getirir. Bu bağlamda eğitimin toplumsal ve ekonomik birçok etkiye sahip olduğu söylenebilir. Çünkü eğitim günümüzde teknolojik ilerleme ve gelişimin yapı taşını oluşturmaktadır. Öte yandan eğitim bireylerin bilgi birikimini artırarak ve becerilerini geliştirmesini sağlayarak beşerî sermayeye etki etmekte ve istihdamları üzerinde etkili olmaktadır. Yani eğitim beşerî sermayeye etki ederek bireylerin istihdam edilmelerini artırabilmekte veya işsiz kalma olasılıklarını azaltabilmektedir. Eğitimin bu etkisinin cinsiyete göre farklılık gösterip göstermediği ise güncel bir araştırma konusudur. Bu bağlamda çalışmanın amacı eğitim harcamaları ve genç kadın/erkek işsizliği arasındaki nedensellik ilişkisinin araştırılmasıdır. Çalışmada Türkiye’de 1988-2020 dönemi kamu eğitim harcamaları ve genç kadın/erkek işsizlik verileri Fourier Granger nedensellik testiyle analiz edilmiştir. Çalışmanın sonucuna göre eğitim harcamalarından genç kadın işsizliğine doğru bir nedensellik ilişkisi bulunduğuna ulaşılmıştır. Genç kadın işsizliğinden eğitim harcamalarına; eğitim harcamalarından genç erkek işsizliğine, genç erkek işsizliğinden eğitim harcamalarına doğru ise nedensellik ilişkisi bulunmadığı tespit edilmiştir.
Proximidad, demora y cuidados: El activismo urbano de Territorio Tolosa
Authors:   , Di Meglio Juan Francisco
Published: July 2023

En esta investigación analizamos las prácticas de acción colectiva de Territorio Tolosa, colectiva que realiza lo que denominamos activismo urbano en La Plata. Nos interesó abordar su actividad durante el año 2020, con el ciclo de charlas performáticas “(re!) parar” como insumo para la construcción de datos, poniendo la mira en lo que consideramos los instrumentales centrales del activismo de Territorio Tolosa: las nociones de Proximidad, Demora y Cuidados. El encuadre general que tiene el trabajo es el de dar cuenta y analizar repertorios de acciones de activismo urbano en un escenario marcado por políticas urbanas regresivas. Así las cosas, durante esta tesis tomamos como tareas de investigación, por un lado, el indagar en los repertorios de activismo – sus influencias filosóficas, las mencionadas tres nociones centrales, la articulación de Territorio Tolosa con otras colectivas – y, por otro, radiografiar la configuración espacial y las políticas urbanas platenses, sobre todo aquellas que dialogaban con el referente empírico seleccionado. La investigación se desarrolló en base a una estrategia metodológica cualitativa que permitió adentrarnos de manera profunda en los modos de significación y prácticas de los sujetos, realizando un estudio de caso, y utilizando herramientas como la descripción densa, la etnografía digital, el análisis del discurso y de los usos de las imágenes.

In this paper, we introduce the concept of ϕ-2-absorbing primary hyperideals in multiplicative hyperrings. Several results concerning ϕ-2-absorbing primary hyperideals are proved. We prove under certain conditions that the intersection of two ϕ-2-absorbing primary hyperideals is also a ϕ-2-absorbing primary hyperideal. Examples of ϕ-2-absorbing primary hyperideals are also studied

Indonesia merupakan negara yang kaya akan biota laut, salah satunya adalah makro alga. Pembuatan review artikel ini dilakukan untuk menambah pengetahuan tentang ilmu bahari khususnya dalam isolasi metabolit sekunder pada makro alga. Kelompok makro alga atau lebih dikenal dengan sebutan rumput laut merupakan tumbuhan tingkat rendah yang memproduksi senyawa metabolit sekunder. Isolasi pada makro alga menunjukkan adanya senyawa metabolit sekunder yang terkandung (flavonoid, steroid, terpenoid, alkaloid, fenol, saponin). Metode yang digunakan pada review ini merupakan suatu tinjauan literatur (literatur review) terhadap lima jurnal dan berdasarkan teori-teori yang relevan. Adapun untuk mendapatkan ekstrak sampel dilakukan teknik yang sama yaitu maserasi menggunakan pelarut yang sesuai karakteristik zat yang akan diisolasi selama 1-3 hari. Sedangkan untuk mengisolasi senyawa metabolit sekunder digunakan teknik kromatografi kolom, kromatografi gas-spektometri massa (GC-MS) dan kromatografi lapis tipis (KLT).

Introduction. The article analyzes social security components and its interaction with social cohesion. Approaches to understanding social security and its elements are considered. Key approaches to understanding social cohesion and its components are presented. The main indicators of social security and social cohesion and their impact on society's current social development are investigated. Directions for further development of their effective interaction with the aim of forming high-quality social capital are identified.
Aim. The aim of the article is to study key features of the formation of social security and cohesion, taking into account current trends in society.
Method (methodology). The methodological foundation of the study is based on scientific works on the current state and peculiarities of the formation of social security and cohesion. Dialectical, systemic, and synergistic approaches were used at all stages of the study along with the methods of general scientific cognition: comparison, analysis and synthesis, induction and deduction.
Results. Globalization processes and current crises in the world, pandemic challenges and war in our country, the socio-economic problem of increased export orientation, dependence on energy imports and shortcomings in domestic market development significantly raise the issue of social security at all levels. The decline in the standard of living and quality of life, imperfect reforms in Ukraine's economy, social deformations and property inequalities that lead to aggravation of social confrontations in society require analysis and assessment of the level of social security in order to improve the population's welfare.
In modern conditions, there are different approaches to defining social security and social cohesion. Moreover, the criteria and indicators of social security in the European Union have been considered and improved for quite some time. One of the possible indicators of the effectiveness of social security can be the Social Progress Index, which is an integral indicator and is determined by a number of parameters and criteria. The goal of further research is to structure the components of social security and clearly define the role of social cohesion in it.
