Authors: Rincón Martínez Julio César , García Gómez Carmen , González Trevizo Marcos Eduardo
Published: April 2022

Los estudios sobre confort térmico desarrollados bajo las bases metodológicas del enfoque adaptativo, advierten una dependencia importante de la sensación térmica de los sujetos respecto a las condiciones climáticas exteriores del lugar habitado. Las condiciones adversas del ambiente térmico pueden influir negativamente en el bienestar, la eficiencia y el confort de los sujetos, lo que deriva en la subutilización de los espacios cuyas condiciones higrotérmicas son inapropiadas para la actividad para la que fueron construidos. El objetivo de este trabajo consiste en estimar el rango de confort higrotérmico para espacios exteriores en dos bioclimas representativamente extremos en México: Cálido-húmedo y Semifrío-seco. El primero presenta una temperatura media anual de 26.2 °C y una precipitación total anual de 1,094.8 mm, mientras que el segundo, una de 17.3 °C y una de 217.3 mm, respectivamente. Los estudios son de tipo correlacional y fueron analizados con 605 evaluaciones y el registro simultáneo de la temperatura, la humedad relativa y la velocidad de viento, durante el periodo cálido. Los cuestionarios aplicados se diseñaron con base en la ISO 10551 y la ANSI/ASHRAE 55; asimismo, los instrumentos de medición física se establecieron a partir de la ISO 7726. Los datos recabados fueron procesados estadísticamente con el método de Medias por Intervalos de Sensación Térmica. El rango de confort higrotérmico estimado para el bioclima Cálido-húmedo fue de 21.8 °C a 34.9 °C para la temperatura y de 38.3 % a 85.8 % para la humedad relativa, mientras que para el Semifrío-seco fue de 19.4 °C a 25.0 °C y de 54.2 % a 84.0 %, respectivamente. Estas estimaciones responden a la adaptación que las personas presentan con su ambiente inmediato, a razón de las condiciones climáticas locales de cada lugar y el periodo de evaluación estudiado.
Metodología para encontrar la deformación volumétrica de un suelo expansivo y parcialmente saturado con la menor cantidad de ensayes posible
Authors: Méndez Herrada Iliané , Pérez Rea María de la Luz
Published: April 2022

La deformación volumétrica es un parámetro fundamental para el cálculo de los asentamientos de ciertos y determinados tipos de suelos dentro de un estudio geotécnico, particularmente de los suelos arcillosos y con grandes potenciales de expansión. En este trabajo se pretende encontrar una metodología que nos permita llegar a este valor con la menor cantidad de ensayes posibles, pero manteniendo su efectividad y precisión. Para tal propósito se estaría empleando un modelo constitutivo elastoplástico desarrollado por Verdín Montes. Debido a que este modelo es solo aplicable a suelos arcillosos o con un alto contenido de finos, la metodología también queda condicionada a este tipo de suelos, por lo que previamente se debe contar con la información de su clasificación. La implementación de un modelo para suelos no saturados en el cual la variable de esfuerzo efectivo permita simplificar las ecuaciones constitutivas, representa la unificación de todas las teorías de mecánicas de suelos en una sola ecuación. Es por ello que este modelo ofrece grandes ventajas ante las deformaciones que presentan los suelos expansivos. Para encontrar la deformación volumétrica se deben realizar ordenadamente las siguientes pruebas: Cálculo de succión, grado de saturación y elaboración de la Curva de Retención Agua-Suelo, cálculo de la relación de vacíos inicial y máxima, determinación de los parámetros generales k y l, cálculo de la relación de vacíos mínima, cálculo de los esfuerzos efectivos mediante la ecuación planteada en este artículo, cálculo de la densidad relativa, cálculo del índice de expansión y el índice de expansión-colapso, y por último la determinación de la deformación volumétrica mediante la ecuación descrita
Multi Images Steganography using Neural Network

Published: April 2022

Abstract: Currently, the most successful approach to steganography in empirical objects, such as digital media, is to embed the payload while minimizing a suitably defined distortion function. The design of the distortion is essentially the only task left to the stegnographer since efficient practical codes exist that embed near the payload-distortion bound. The ractitioner goal is to design the distortion to obtain a scheme with a high empirical statistical detectability. In this paper, we propose a universal distortion design called universal wavelet relative distortion (UNIWARD) that can be applied for embedding in an arbitrary domain. The embedding distortion is computed as a sum of relative changes of coefficients in a directional filter bank decomposition of the cover image. The directionality forces the embedding changes to such parts of the cover object that are difficult to model in multiple directions, such as textures or noisy regions, while avoiding smooth regions or clean edges. We demonstrate experimentally using rich models as well as targeted attacks that steganographic methods built using UNIWARD match or outperform the current state of the art in the spatial domain, JPEG domain, and sideinformed JPEG domain.

Published: April 2022

Abstract: The world faced so many problems during the Covid-19 pandemic. Washing our hands was an integral part of preventive measures of the Covid-19. But it is found that it wastes so much water in the world. Many people do not have access to clean drinking water and face water scarcity. The sanitizer is also used by many people. But excessive use of sanitizer with high alcohol concentration leads to dry, itchy skin. The indirect consumption of sanitizer through the hands leads to the risk of other health conditions. In this proposed system, fog making technology is used for dispensing sanitizer. So that only the required quantity of sanitizer is dispensed and it covers the entire surface area of hands, guaranteeing the disinfection of hands. This system is proposed to reduce water usage by around 90%. It also saves 20-30% of the water that rolls over the hands while washing the hands and also the water required for washing hands. This system did not completely replace the handwashing method but it helped in saving a remarkable quantity of water. It also helped in preventing skin diseases and other potential health hazards.

Published: April 2022

Abstract: In recent times, monitoring health round the clock is crucial. These data must be transferred to the hospital in realtime, which is usually done with the help of Wi-Fi. There can be delays in transferring due to various reasons. To tackle this, we can use Light Fidelity (Li-Fi). Li-Fi uses light as a medium to transfer data. As the speed of light is faster, the data can be transferred very quickly. This will help by alerting the medical staff early and letting help get to the needed in a faster period. In rural areas, there may be fewer facilities having a Wi-Fi connection, but light will be easily available. So, by using Li-Fi, the senior citizens, or a person in need of round-the-clock care with have better care.

Corporate Governance Practices in Building Sustainable Development in Present Indian Scenario
Authors: Yadav Dr. Sushama
Published: April 2022

Abstract: Corporate Governance (CG) is concerned with a set of principles, ethics, values, morality, rules, regulations, and procedures, among other things. The global economic environment is long-term expansion. Enterprises should base their positions on transparency and an integrated approach to sustainable products and services, and their active participation of all stakeholders should contribute to society's and the planet's general well-being. It is not enough to have a one-time or shortterm accountability policy; it must be a long-term, consistent corporate mindset. It frequently necessitates fundamental shifts in the mindset of business owners, managers, and employees, who consider the long-term interests of society in addition to their own corporate goals and customer wants and wishes. Corporate governance and its practices are the major research concerns among industries, academicians, and scholars from the few decades. Academic research, particularly on sustainability indexes, has brought corporate governance and corporate social responsibility closer together in recent years. In fact, the most important indexes consider corporate governance, as well as other environmental and social factors. In this present article it has tries to discuss the role of corporate governance and their practices in building sustainable development in present Indian scenario. Keywords: Corporate Governance, Building, Sustainable Development, Ethics, Principles, Social, etc.

A study was conducted to survey rust fungi which the insect Mycodiplosis Rübsaamen (Diptera: Cecidomyiidae) larvae feed on, at different locations along the Syrian coast during 2008-2020. The study showed the presence of gall midge Mycodiplosis spp on 77 plant species feeding on 57 fungal species belonging to 8 genera. Results showed that larvae appeared in March and continued until June on Phragmidium violaceum infecting Rubus sanguineus and on Puccinia menthae infecting Mentha spicata. Whereas, larvae that feed on fungi which infect host plant late in October, appeared at the beginning of infection and continued until November, such as Cerotelium fici on Ficus carica. The results showed a difference in the frequency of the presence of Mycodiplosis larvae on the plant families and varieties of rust fungi. The occurrence of Mycodiplosis larva on 12 plant families was 100% due to presence of larva on all rust-infected plant families, whereas occurrence rate on some plant families varied and reached 92.31% on Fabaceae plants, and no presence was observed on Plumbaginaceae plants. Second stage larvae consumed 82.37% of the uredio-pustules of Puccinia conclusa. Keywords: Biological control, Diptera, Cecidomyiidae, Mycodiplosis, Uredinales, Syria

Published: April 2022

The phytohormone ethylene is one of the main causes of postharvest spoilage of fruits and vegetables. The effective management of ethylene concentration is of great importance to reduce postharvest losses of fruits and vegetables. The reduction in ethylene caused by using KMnO4 was found to delay the ripening of many climacteric fruits such as apple, bananas, melons and tomatoes. Interestingly, the general aim of this work is to evaluate the effectiveness of KMnO4 in reducing ethylene concentration during storage of climacteric fruit. For this purpose, ethylene-enriched mixture was passed inside a cylinder with a bed of activated carbon treated with KMnO4 and t gas samples entering and exiting the cylinder were analyzed for ethylene concentration by injecting in gas chromatography (GC-FID) after 15, 30, and 45 minutes and results obtained were compared with a similar set up but with only activated carbon as ethylene adsorber. The results showed that maximal ethylene removal was in the cylinder with activated carbon treated with KMnO4 which removed 91.71% of ethylene 45 min after treatment compared with 61.93% ethylene removal by only using the activated carbon. The results also revealed that the activated carbon with KMnO4 10 days after storage reduced ethylene concentration by 43.94% compared with 28.77% for the activated carbon. Keywords: Ethylene, activated carbon, KMnO4, climacteric fruit, adsorption, GC-FID.

Produto de uma pesquisa de pós-doutorado e de discussões promovidas em eventos internacionais da Rede Acadêmica Verano TIC, este artigo foi criado a partir da inquietude de três pesquisadores (do Brasil, Chile e Bolívia) e parte do pressuposto de que a escola é, ou deveria ser, um espaço dinâmico de transformação. Assim, buscamos discutir os possíveis desdobramentos e caminhos que surgem na construção de um novo desenho da sociedade e, porque não dizer, de escola. De um modo geral, a pandemia de Covid-19 revelou narrativas, respostas, incertezas e desencontros, em um estado geral de crises dentro da crise. A partir do depoimento de três professores experientes da educação básica, os quais são convidados a refletir sobre as mudanças da escola ao longo dos anos, este artigo traz uma discussão a partir de diferentes autores da educação e áreas afins. Vale ressaltar que este se baseia na abordagem qualitativa, adotando a análise dos depoimentos a partir de oito questões que norteiam o diálogo com os professores. Tendo em vista as reflexões promovidas, que abre uma janela para profundos debates sobre a escola e seu futuro pós Covid-19, se faz urgente um trabalho coletivo para pensar o modelo de escola e de formação que queremos e necessitamos.

Published: April 2022

Objetivou-se investigar as dificuldades encontradas por estudantes no ensino superior, suas condições subjetivas que interferem no sucesso ou fracasso na universidade e as práticas que instituições estão adotando para dirimir tais problemas. Foi realizada uma revisão de literatura com busca sistematizada, que permitiu a recuperação de 51 trabalhos entre teses, dissertações e artigos científicos. Os resultados apontam que os estudantes enfrentam dificuldades principalmente no primeiro ano de curso, período em que ficam evidentes problemas de adaptação. Além do mais, estudantes demonstram dificuldades com estratégias de estudo, relação professor-aluno e pares, aulas expositivas e ferramentas de avaliação. Estudantes que se sentem vocacionados em relação ao curso, com autoestima elevada, autoconceito positivo e sentimentos de autoeficácia, tendem a superar melhor as dificuldades. Pesquisas sugerem que as universidades implantem programas de apoio ao estudante.

Do espetáculo, da liquidez e da desinformação. Nossa sociedade é exaustivamente rotulada e analisada por pensadores e pesquisadores interessados em compreender quais mecanismos estruturam as relações e construções sociais. Mecanismos que também são capazes de nos desviar de assuntos importantes da pauta pública ou, simplesmente, aliviar o peso da realidade coletiva. Neste artigo, refletimos sobre tais fenômenos dentro de um ambiente em rede, onde tudo se interconecta com agilidade e se dissolve na mesma velocidade. Em tal contexto, levantamos exemplos das técnicas discursivas de Bolsonaro a fim de entender como a maior liderança do país protagoniza um espetáculo interativo e constante de ódio, desinformação e tensão permanente.

COVID-19 pandemic telephone two-week-wait referrals in Head and Neck cancer – How safe were they?: A retrospective cohort study
Authors: Lau Kin Lun , Wilson Margarita , Oozeer Nashreen , Cocks Helen
Published: April 2022

Key Points 1. During the COVID-19 pandemic, NHS cancer referral guidance
recommended a move from face-to-face clinics to telephone appointment.
In this study, we reviewed the safety of telephone clinic for urgent
2-week wait cancer referrals. 2. In the 7 months study period during the
COVID-19 pandemic, 1062 urgent 2-week wait cancer referrals were
received in our regional head and neck specialist unit, reflecting a
7.3% decline compared to pre-pandemic data. 3. At 6-months follow-up,
98 (9.2%) patients received a new diagnosis of malignancy. 95 of them
received their diagnoses promptly after their initial telephone clinic,
whereas 3 patients received a delayed diagnosis. 4. There is a late
diagnosis rate of 0.28% but we discussed in our cases that late
diagnosis does not inevitably lead to worse clinical outcome or harm. 5.
Telephone clinics will likely remain in some capacity after the
pandemic, while telephone clinics are pragmatic means to maintain
patient flow during the pandemic, they could result in risk of late
diagnosis.
Rigorous homogenisation of an optimal control problem for multispecies diffusion-reaction equations
Authors: Kundu Arghya , Mahato Hari
Published: April 2022

We study an optimal control problem governed by diffusion-reaction
equations in a periodic porous medium (bounded domain). Our control
problem is equivalent to a convex minimization problem. We take a
$L^2$-cost functional and pose controls on the mobile species
present in the pore part of the domain. One of the main aims here is to
characterize a given control to be an optimal control for the
microscopic problem. We obtain the existence of solution of the control
problem and analyse a relation between optimal control and its adjoint
state. Then, we do the homogenization of the optimal control problem
(diffusion-reaction model with cost functional) by a formal asymptotic
analysis and then via rigorous two-scale convergence and periodic
unfolding method.

Authors: Pelland-Marcotte Marie-Claude , Tole Soumitra , Bouhelier Eve , Lee Susan , Halparin Jessica , Mammen Cherry , Lyons Karen , Amid Ali
Published: April 2022

Thromboembolism is a major complication of nephrotic syndrome (NS).
Hypoalbuminemia, loss of anticoagulant proteins, increased procoagulant
proteins, hemoconcentration, and platelet activation contribute to a
hypercoagulable state. Despite being well-described, the optimal
management of thromboembolism in NS remains unclear. Rivaroxaban, a
direct factor-Xa inhibitor has recently been shown to be safe and
efficacious in treating pediatric venous thromboembolism but has not
been well studied in NS. We present an adolescent with steroid-dependent
NS, deep vein thrombosis and submassive pulmonary embolism successfully
treated with rivaroxaban. We perform a systematic review of the reported
safety and efficacy of direct factor-Xa inhibitor in this population.
Efficacy and safety of permissive hypercapnia in preterm infants: A systematic review
Authors: Ozawa Yuri , Miyake Fuyu , Isayama Tetsuya
Published: April 2022

Context: In adults, permissive hypercapnia reduces mortality
and ventilation duration. However, in preterm infants, findings from
past research regarding the efficacy and safety of permissive
hypercapnia are controversial. Objective: To evaluate the
efficacy and safety of permissive hypercapnia versus normocapnia in
preterm infants on mechanical ventilation. Data Sources:
MEDLINE, EMBASE, CENTRAL, and CINAHL Study Selection: Published
randomized controlled trials (RCTs), non-RCTs, interrupted time series,
cohort studies, case-control studies, and controlled before-and-after
studies were included. Data Extraction: Two reviewers
independently screened the title and abstract and full text, extracted
data, assessed the risk of bias, and evaluated certainty of evidence
(CoE) according to the Grading of Recommendations Assessment,
Development and Evaluation approach. A meta-analysis of RCTs was
performed using the random-effects model. Results: Four RCTs
(693 infants) and one cohort study (371 infants) were included. No
significant differences existed between the permissive hypercapnia and
normocapnia groups for bronchopulmonary dysplasia (BPD) (risk ratio
[RR] 0.94; 95% confidence interval [CI] 0.74-1.18; very low
CoE) and a composite outcome of death or BPD (RR 1.05; 95% CI
0.90-1.23; very low CoE). Permissive hypercapnia may increase
necrotizing enterocolitis (RR 1.69; 95% CI 0.98-2.91; very low CoE),
although the null or trivial effect cannot be excluded. No significant
differences existed between the two groups for any other outcome
assessed (very low-to-low CoE). Limitations: The sample sizes
were less than the optimal sizes for all outcomes assessed, indicating
the need for further trials. Conclusions: Permissive
hypercapnia did not have any significant benefit or harm in preterm
infants.
A lentinan-loaded hydrogel with a core-shell structure in-duces broad-spectrum resistance against plant virus by acti-vating the expression of CML19

Published: April 2022

Control of plant virus disease largely depends on the induced plant
defense achieved by the external application of synthetic chemical
inducers with the ability to modify defense-signaling pathways. However,
most of the molecular mechanisms underlying these chemical inducers
remain unknown. Here, we developed a lentinan-loaded hy-drogel with a
core-shell structure and discovered how it protects plants from
different virus infections. The hydrogel was synthesized by adding a
chitosan shell on the sur-face of the polyanion sodium alginate-calcium
ion-lentinan (LNT) hydrogel (SL-gel) to form CSL-gel. CSL-gel exhibits
the capacity to prolong the stable release of lenti-nan and promote
calcium ions release. Application of CSL-gel on the root of plants
induces broad-spectrum resistance against TMV, TuMV, PVX and TRV.
Further-more, RNA-seq analysis identified that the calmodulin-like
protein 19 gene (CML19) is upregulated by the sustained release of
calcium ions from the CSL-gel, and silenc-ing and overexpression of
CML19 alter the susceptibility and resistance of tobacco to TMV. Our
findings provide evidence that the novel and synthetic CSL-gel with the
sustainable release of LNT and calcium ion strongly inhibits the plant
virus infection. This study uncovers a novel mode of action by which
CSL-gel with the stable release of calcium ion triggers CML19
expression.

Assessment of a score of clear or nearly clear(PGA0/1,IGA0/1)) and the
paitents who reported adverse events (AEs) at 4-12 weeks. Secondary
criteria were the propotion of patients with 75 % reductions in
Psoriasis Area and Severity Index (PASI 75) and the number of patients
who reported drug withdrawal due to adverse events at 4-12 weeks.We
combined with hierarchical cluster analyses to consider efficacy, safety
and tolerability. Results: The review included 24 randomized controlled
trials of topical treatments for plaque psoriasis with 9748
participants. This network meta-analysis showed that topical treatments
were significantly more effective than placebo at 4-12weeks, in addition
to tofacitinib ointment. hierarchical cluster analyses shows that
topical calcipotriene and betamethasone
dipropionate(Cal/BD),roflumilast,betamethasone,halobetasol-propionate
and tazarotene(HP/TAZ), halobetasol were comparable with respect to high
short-term efficacy, safety and tolerability, especially Cal/BD and
roflumilast.

The role of topographical pattern on cell behavior regulation has been
recognized but has not been elucidated yet. Here, using soft lithography
techniques to allow mass-production of microgrooved substrates with
varying dimensions at mesoscopic scale (from single-cell to
multicellular scale), we identified the spatial distribution of cancer
cells in response to topographical pattern due to contact guidance. We
observed that increasing depth and groove width is accompanied by more
obvious preferential distribution on ridges. Determination of cell
density and migrate velocity signatures reveals that the preferential
distribution on ridges is caused by cell upward migration. Then, based
on the investigation of influences of soluble factors concentration and
quantification of cell-substrate adhesion, the cell upward motility was
considered to be governed by cell-substrate adhesion caused by contact
guidance due to different constraints. Interestingly, in response to the
topological feature dimensions, the upward migration of cells is driven
by alternative mechanisms based on FAs (focal adhesions) constraints
(single-cell scale) and entropic maximization (multicellular scale).
Understanding the mechanism of contact guidance on mesoscopic scale
provides basic support for the study of cell alignment and migration,
thereby aiding in disease progression prediction, especially for cancer
metastasis.

After implantation of a biomaterial, both the host immune system and
properties of the material determine the local immune response. In a
scaffold-induced immune micro-environment, immune cells like macrophages
present functional heterogeneity and plasticity. With the advancement of
technology, emerging techniques such as single-cell RNA sequencing
(scRNA-seq) enable high-resolution characterization of immune cell
populations. In-depth understanding of the interaction between scaffolds
and the host immune system helps to provide clues for the design of
biomaterials to optimize regeneration and promote a pro-regenerative
local immune micro-environment. In this review, we discuss the
procedures of foreign body reaction in brief, present recent advances in
elucidating mechanisms of foreign body response, and discuss the
application of scRNA-seq in probing the scaffold immune
micro-environment. With regard to biomaterial design, we summarize the
influences that physical and chemical properties of biomaterials have on
cell behaviors in the micro-environment and provide some reference to
designing immunomodulatory biomaterials.

Tujuan: Penelitian ini akan membahas mengenai, pertama, bentuk perlindungan hak cipta pada platform Youtube menurut Undang-Undang Hak Cipta (UUHC). Kedua, aturan hukum yang berkaitan dengan digital kreatif pada platform YouTube menurut Undang-Undang Informasi dan Transaksi Elektronik (UU ITE).Metodologi: Penelitian ini menggunakan metode pendekatan yuridis normatif berdasarkan peraturan perundang-undangan yang dikonsepkan sebagai kaidah atau norma yang menjadi patokan berperilaku manusia yang dianggap pantas. Data yang digunakan berupa data sekunder dengan mengkaji literatur serta peraturan perundang-undangan terkait hak cipta dan korelasinya dengan hukum teknologi informasi dan transaksi elektronik dalam digital platform YouTube. Analisis data yang digunakan bersifat yuridis kualitatif.Temuan: Penelitian ini menunjukkan pemerintah Indonesia belum secara maksimal melindungi pencipta, pemegang hak cipta dan bahkan content creator yang telah mewujudkan ide kreatifnya ke dalam bentuk konten video di YouTube. Di samping itu, masih maraknya praktik pelanggaran hak cipta dalam digital platform YouTube juga merupakan bukti bahwa aturan hukum yang berlaku saat ini belum dapat menjawab persoalan di atas.Kegunaan: Hadirnya mekanisme hukum yang secara bersamaan mampu memenuhi hak eksklusif dari pencipta serta content creator guna mewujudkan digital kreatif sebagai bentuk pembangunan ekonomi Indonesia menjadi kenyataan dan menghindari benturan kepentingan antar kedua belah pihak. Di samping itu, diperlukan sebuah aturan hukum yang spesifik dan konkret dengan sanksi yang tegas terhadap perbuatan pelanggaran hak cipta sebagai bentuk perlindungan hak cipta secara maksimal.Kebaruan/Orisinalitas: Berbeda dengan penelitian yang telah dilakukan sebelumnya, tulisan ini memiliki perbedaan yang menekankan pada aspek digital kreatif sebagai salah satu pengembangan dari ekonomi kreatif yang bertumpu pada peranan digital platform.

Authority in resolving disputes regarding the results of general elections is the authority of the constitutional court granted by the constitution. While the authority in resolving violations is structured, systematic and massive is the authority of the electoral supervisory body granted by law. In the dispute over the results of the general election, which was decided by the constitutional court, the constitutional court did not have the authority to test the petition filed on the basis of a structured, systematic and massive violation because the constitutional court only based on the dispute over the results as intended in its authority. The court verdict has been in accordance with the authority held according to the original instruction given by the constitution, which wants the implementation of elections that are sovereign and carried out on a direct, public, free, confidential, honest and fair basis.

The global economic crisis has resulted in various global financial institutions experiencing losses and bankruptcy. The recurring global financial crisis in the world requires solutions to be resolved and prevented. The global economic crisis has resulted in various global financial institutions experiencing losses and bankruptcy. The perfect Islamic Sharia is able to provide a way out of the grip of the global economic crisis that has hit many countries today. The Islamic economy is one of the significant steps the government must take in dealing with negative spreads and the vulnerability of the global economy. Sharia banking is considered to be more crisis resistant than conventional banking if economic conditions deteriorate. This is because Islamic banking is more flexible in dealing with any situation. Islamic banking is increasingly recognized in the community from day to day. Not only for Muslims, but also for those who are non-Muslims. This study aims to determine the Islamic economy as the best solution in solving the problem of the global economic crisis. The data used in this research is secondary data. The results of this study indicate that the Islamic economy is a solution to the global economic crisis. Islamic banking can help in overcoming the burden of the crisis in the short term and also in the future.

Published: April 2022

The purpose of this article is to find out how international law plays a role in the Israeli-Palestinian war during the Covid-19 pandemic. The method in writing this article was a literature study by collecting literature from journals and books relevant to the topic, then analyzing it, and then making conclusions. The emergence of the Covid-19 pandemic that spreads rapidly raises concerns about the socio-economic conditions of Palestinian citizens. The challenge is getting bigger in tackling these two problems simultaneously. The condition of Palestinian citizens is increasing concerning with the destruction of WASH facilities (water, sanitation, and hygiene), the inhibition of the supply of necessities that will enter the Palestinian state, as well as the destruction of the natural environment since these aspects can be used to prevent the spread of the Covid-19 virus. International humanitarian law actually exists to limit the occurrence of such incidents, but these regulations are violated by the military and the Israeli government. This article is helpful to find out how the actions of the state of Israel against Palestine during the Covid-19 pandemic are based on the perspective of international law. This article was compiled with references to various literary sources from national and international journals and books. In addition, it also uses the latest news from the topics discussed. The result of this literature study is that the conflict that is being experienced by Israel and Palestine is not getting better with the increasing number of attacks on Palestinian civilians.
