Demand Theory of Sharia Micro Economic Perspective
Authors: Makrifah Ririn , Rahman Miftahur
Published: March 2024

The purpose of writing this article is to find out about the theory of demand in sharia microeconomics and what is related to the discussion of the theory of microeconomic demand. Economics is a human act as a consumer to fulfill needs and desires or make various requests for various goods and services in everyday life. Islamic economics itself is never separated from moral and religious values because every activity is always associated with the Shari'a. Islamic economics is the knowledge and application of sharia law to prevent injustice in the use and disposal of material resources with the aim of providing human satisfaction and carrying out these activities as an obligation to Allah and society. The Qur'an calls the economy the term istishad (saving, economy) which literally means "middle" or "moderate". Therefore, as Muslims we must take a moderate stance in acquiring and using resources. A Muslim is not allowed to be stingy (royal, exaggerating) nor is he allowed to be stingy (bakhl). The view of Islamic economics regarding demand is almost the same as conventional economics, but there are limitations for individuals to behave economically in accordance with sharia rules. In Islamic economics, "Islamic" norms and morals, which are Islamic principles in economics, are a determining factor for an individual or society in carrying out their economic activities. Therefore, Islamic economic theory is different from conventional economic theory

Krisis keuangan global juga berdampak pada sektor perbankan, salah satunya dalam melakukan penyaluran kredit. Bank lebih selektif dalam melakukan kebijakannya untuk penyaluran kredit, sehingga hal ini memunculkan fenomena credit crunch. Pada sektor perbankan syariah, fenomena credit crunch lebih identik dengan penggunaan istilah financial crunch.. Fenomena ini memiliki hubungan dengan tingkat pembiayaan bank, karena saat terjadinya krisis keuangan bank lebih selektif dalam menyalurkan pembiayaannnya, disinilah terjadi perubahan dalam penawaran dan permintaan pembiayaan. Adapun variabel yang digunakan untuk menjelaskan pengaruh financial crunch pada bank syariah yaitu Non Performing Financing (NPF), Dana Pihak Ketiga (DPK), dan Financing To Deposit Ratio (FDR), serta adanya variabel pembiayaan UMKM untuk melihat pengaruh nya terhadap pertumbuhan ekonomi di Indonesia, yang diproyeksikan dengan data IPI. Dalam penelitian menggunakan model analisis Vector Error Correction Model (VECM) menggunakan data time series bulan Januari 2010 – Maret 2021. Hasil penelitian ini menunjukkan tidak adanya fenomena financial crunch pada saat terjadinya krisis keuangan, serta adanya perubahan pembiayaan UMKM juga tidak dapat menekan angka IPI. Kata Kunci : Financial Crunch, NPF, DPK, FDR, Pembiayaan UMKM, Pertumbuhan Ekonomi, IPI, VECM.

Published: March 2024

Ninguém tem dúvidas de que os alinhadores são os aparelhos mais requisitados do momento. Mas o que poucos sabem é que, entre vários fatores críticos, a colaboração do paciente, ou seu grau de adesão, é uma das principais causas de insucesso nos tratamentos ortodônticos. Pois é, costumo dizer que não existe “o melhor” aparelho, “a melhor” prescrição, nem aparelho milagroso... Existem possibilidades de escolhas, sempre com importantes limitações presentes em todos os sistemas de aparelhos, quer sejam fixos ou removíveis, dependendo do tipo de paciente que estamos tratando.

Published: March 2024

INTRODUÇÃO: É importante determinar o limite aceitável de protrusão e retrusão dos incisivos superiores para alcançar o melhor diagnóstico associado à satisfação do paciente em relação à estética do perfil.OBJETIVO: Avaliar a influência da posição anteroposterior dos incisivos centrais superiores na atratividade facial, julgada por ortodontistas e leigos. MÉTODOS: Fotografias de perfil facial de dois indivíduos sorrindo, com ângulo de convexidade facial, altura vertical e proporção facial dentro da normalidade, foram digitalizadas e manipuladas para simular protrusão (+) e retrusão (-) dos incisivos centrais superiores em incrementos de 1 a 5 mm. Para determinar a atratividade facial, as imagens foram avaliadas por 20 ortodontistas e 20 leigos. Modelos lineares generalizados foram desenvolvidos, considerando distribuição, assimetria e desfecho, tipo (ortodontista ou leigo) e sexo como efeitos dos gráficos e incrementos na posição anteroposterior dos incisivos superiores como subparcelas. RESULTADOS: Os ortodontistas consideraram o intervalo entre -2mm a +5mm o mais atrativo. Os leigos acharam o intervalo entre -3mm e +5mm o mais atrativo. Os ortodontistas do sexo masculino atribuíram uma pontuação de atratividade significativamente maior à imagem com retrusão de -2 mm do que as ortodontistas (sexo feminino). Não foram encontradas diferenças estatisticamente significativas quando comparados ortodontistas e leigos. CONCLUSÃO: A posição anteroposterior dos incisivos superiores influenciou na atratividade facial dos diferentes graus de retrusão e protrusão. Incisivos superiores retruídos foram considerados menos atrativos. Não houve diferença na avaliação da atratividade do perfil facial entre ortodontistas e leigos e entre homens e mulheres.

Authors: Consolaro Alberto
Published: March 2024

INTRODUÇÃO: O uso de aparelhos ortodônticos que podem ser removidos pelos pacientes, de acordo com sua vontade e/ou necessidade, implica em conhecermos os fenômenos celulares e teciduais da primeira fase passiva da movimentação dentária induzida e sua transição para a segunda fase ativa, o que requer a mobilização de osteoclastos para que ocorra a reabsorção óssea. MÉTODOS: Informações já publicadas foram resgatadas dos trabalhos clássicos e mais significativos, nos quais as pesquisas revelaram os fenômenos periodontais nessas primeiras 24 horas, inclusive a Teoria das 10 horas, de Andrews. DISCUSSÃO: Entre a primeira e a segunda fases, tem-se a mobilização e ativação dos osteoclastos; mas, se houver interrupção da força, pode acontecer a desmobilização e até a remobilização dessas células, e isso pode atrapalhar a velocidade e o tempo esperado de movimentação, a depender de alguns fatores. CONCLUSÃO: É fundamental o profissional conhecer detalhadamente esse processo, para instruir e convencer o paciente a usar o aparelho da forma mais contínua possível, para se obter os melhores resultados clínicos.

The results of the study showed that the growth of Gracilaria sp. polyculture with milkfish provided absolute growth of 3615.89 ± 330.84 g; Relative Growth Rate (RGR) 180.79 ± 16.54 %; and Specific Growth Rate (SGR) 2.29 ± 0.13 %/day were significantly higher, compared with the growth of Gracilaria sp. monoculture. Monoculture Gracilaria sp showed absolute growth of 1912.71 ± 386.94 g; RGR 95.64 ± 19.35 %; and SGR 1.48 ± 0.22 %.day-1. Nutrient content in polyculture pond waters revealed nitrate 1.08 ± 0.09 mg.L-1 and phosphate 0.18 ± 0.04 mg.L-1 were significantly higher compared to nutrient content in monoculture pond waters which were nitrate 0.71 ± 0.22 mg.L-1 and 0.07 ± 0.04 mg.L-1. Polyculture Gracilaria and seaweed provide higher production due to the enrichment from nutrient content.
Deconstructing Teacher Engagement Techniques for Pre-service Teachers through Explicitly Teaching and Applying “Noticing” in Video Observations
Authors: Scott Kristina , Rohde Leigh
Published: March 2024

Student engagement is a complex measurement that can be viewed through behavioral, emotional, and cognitive constructs. Authentic intellectual engagement requires more than task compliance and requires teachers to make decisions and moves to promote engagement. Pre-service teachers need to have these teacher decisions deconstructed and explicitly reconstructed to “notice” and make sense of it. This study conducted a qualitative document analysis of 31 pre-service teachers’ observational reflections on a pre-selected video-recorded lesson. A pre- and post-assessment was used. When pre-service teachers were given explicit instruction on “noticing” teacher moves to enhance student engagement through multiple constructs, their understanding of student engagement within a lesson shifted from literal and compliance-focused to a multi-dimensional construct involving behavior, emotion, and cognition. The assessments also shifted focus from what the teachers did to the impact the teacher’s decisions had on student engagement and learning. Future research should look at how noticing skills in video observations can transfer to the pre-service teachers developing their teaching skills in the classroom.

Published: March 2024

The mechanical properties of wood are affected by member size and loading rate. Axial compression tests with different seismic strain rates and sizes of specimens were carried out to investigate the static and dynamic dimensional effects of Yunnan pine timber. And obtained load-displacement curves, compressive strength, modulus of elasticity, peak strain and Poisson’s ratio. Weibull’s weakest chain theory, Bazant’s law of dimensional effects and Carpinteri’s law of multiple fractal dimensional effects were used to analyze the dimensional effects on the compressive strength of wood, and to establish a wood strength model that takes strain rate effects and dimensional effects into account. The results showed that the compressive strength, elastic modulus, and Poisson’s ratio of Yunnan pine wood exhibit both size and strain rate effects. Under the coupling effect of strain rate effect and size effect, the size effect of Yunnan pine wood strength decreases with increasing strain rate, while the strain rate effect increases with increasing size. A size effect model for compressive strength of wood considering strain rate effect based on three theories and experimental data can well describe the dynamic size effect of Yunnan pine wood strength.
Effect of grain size on fatigue strength of 304 stainless steel

Published: March 2024

In this study, three types of 304 stainless steel samples with different strengths were prepared by refining the grain size through rolling. The microstructure of the samples was observed by electron microscopy. The influence of grain size on the static tensile properties and fatigue strength of the material is mainly attributed to changes in the plastic deformation fracture mechanism and micro-deformation mechanism. In addition, a new fatigue strength prediction model is proposed based on the influence of tensile strength and work-hardening capacity. Compared with the staircase method and Basquin formula models, the proposed model maintains the accuracy of fatigue strength prediction while reducing the cost of fatigue experiments. This provides a new approach for predicting the fatigue strength of specific materials and improving anti-fatigue design capabilities.
On the stochastic elliptic equations involving fractional derivative
Authors: Phuong Nguyen Duc
Published: March 2024

This study is focused on finding the solution to the initial value problem for the fractional elliptic equations driven by the Wiener process. First, with some strong conditions on the input data, we establish the regularity of the solution. With relaxed conditions of the input data function, our forward problem is ill-posed in the sense of Hadamard. For this ill-posed problem, the truncation method is used to construct a regularized solution. Under prior assumptions for the exact solution, the convergence rate is obtained.

This study aims to synthesize inclusion complex derived from sorafenib (Sor) and hydroxypropyl-β-cyclodextrin (HPβCD) (denoted as [Sor-HPβCD]). The complex of Sor with HPβCD has been synthesized in a mixed solvent of H2O-DMSO, with a DMSO volume fraction of 80 %. The results of FTIR, DSC, and UV–Vis analysis have demonstrated the success of complex formation: the intensity of some characteristic peaks for the Sor binding decreased after complex formation, indicating that a part of the guest molecule has entered the cavity of the HPβCD molecule. This is further supported by the DSC analysis results, showing the transformation of the complex’s crystalline form to an amorphous form. The phase solubility diagram study also indicates that the solubility of Sor significantly increases, approximately 7 times higher than pure Sor, after complex formation. The results of the cell growth inhibition activity test in a water environment show that the complex inhibits the growth of Hep-G2 cells with an IC50 value of 62.4 μg/mL, while pure Sor does not exhibit activity as it is practically insoluble in water.

Grain-preferred orientation significantly influences the brittle fracture mechanism and failure mode of crystalline rocks. However, current grain-based models (GBMs) based on particle flow code (PFC) software are mostly proposed on the basis of the Voronoi tessellation method for grain boundary generation, which is difficult to simulate the heterogeneity of microstructure such as shape and orientation of rock minerals. To study the effect of grain-preferred orientation on macroscopic mechanical properties and microscopic characteristics of crystalline rocks, a novel grain-based microstructure transformation method (MTM) is proposed. Based on the MTM, a GBM with a target aspect ratio and crystal orientation is obtained by transforming the Voronoi crystal geometry through a planar coordinate mapping. Specifically, embedded FISH language is used to control random mineral seed size and distribution pattern to generate Tyson polygons. A polygon geometry that satisfies the rock texture is obtained as a grain boundary by spatially transforming the vertex of the Tyson polygon. The transformed complex geometry is taken as the crystal structure of the GBM, and the Lac du Bonnet granite models with different aspect ratios and crystal orientations were developed in PFC2D. Finally, a series of unconfined compressive strength tests are performed in PFC2D to verify the proposed modeling methods for the geometric variation of the crystals and to study the effects of the preferred orientation of the grains on the macroscopic mechanical properties and microscopic fracture mechanisms of the crystalline rocks from different perspectives.

Published: March 2024

Knowledge of the long-term consequences of child sexual abuse (CSA) is crucial to further develop preventive strategies and treatment programs. The aim of this study is to investigate attachment and mentalizing ability in people who have experienced CSA. Attachment style, measured with the Experiences in Close Relationships-Relationship Structures Questionnaire (ECR-RS), and mentalization, measured with the Reflective Functioning Questionnaire (RFQ), were examined through a quantitative questionnaire survey in a sample of 49 individuals who had experienced CSA, and a control group of 612 with no history of CSA. The CSA group was, to a greater extent, identified with insecure attachment style. In addition, participants with insecure attachment were more likely to use hypomentalizing compared to individuals identified with a secure attachment. No significant association was found between attachment style and the relationship between the victim and the offender or the length of traumatic episodes.
