Published: June 2023

This study aims to describe the concept of Sharia Fintech Lending and its regulatory readiness in Indonesia. Along with the development of technology and online lending issues that are troubling the public, sharia fintech lending grows and develops. However, the challenges of online lending make this industry little known to the public, so its development tends to be slow. In quantitative terms, this industry is not as much as conventional fintech. Therefore the government (OJK) initiated regulations for this industry supported by the DSN MUI Fatwa. However, after it was implemented, it turned out that there were many obstacles that hindered the growth of sharia fintech lending. Based on the research findings, OJK needs to review this regulation to make it more flexible and support the development of Islamic banking fintech more rapidly

Introduction: The objective of this study was to analyse the morbidity and mortality factors of HIV-infected children. Material and Methods: This was a 10-year retrospective study from 1 January 2012 to 31 December 2021. All children aged 0-15 years with a positive HIV serological test or PCR under antiretroviral treatment and having a medical file were followed up in the two CMCs of the Ratoma commune. Results: We collected 183 records of HIV-infected children on antiretroviral treatment. The median age was 3 years with extremes of 2 months and 15 years. More than half (60.1%) were <5 years old. More than half of the children (65.1%) were at WHO clinical stage (3 and 4). 60.8% had anemia with a median hemoglobin level of 10.7 g/dl. Respiratory diseases (39.34%) were the most common morbid events. Almost half (44.3%) were alive and followed up, 17.5% died, 23.5% lost to follow-up and 14.8% transferred. Anemia (18.75%) was the most common cause of death. Maternal non-education (p = 0.001), very low income (p = 0.0001), clinical screening (p = 0.0003), severe immunodepression (p = 0.002), tuberculosis (p = 0.007), clinical stage 3 (p = 0.0001) were the main risk factors associated with deaths. Conclusion: The application of the new WHO recommendations for medical management, which require early initiation of antiretroviral treatment, the improvement of PMTCT performance and the promotion of systematic screening are necessary to reduce the morbidity and mortality of HIV-infected children in our context.
The Impact of the COVID-19 Pandemic on Youth Education
Authors: Vasile Emilia , Radu Brindusa Mihaela , Manea Liliana , Anton Lia
Published: June 2023

The COVID-19 pandemic has led to the closure of schools in 20 countries and the closure of preschools in 19 countries in Europe and Central Asia. This affected a total of 49.8 million children, from preschool to high school, who had a very disruptive last semester of school (if there was one at all), culminating in the closing schools. The pandemic has deeply affected education and aggravated the existing social inequities in the region. Children from low-income families, children living in rural areas with poor infrastructure, children from ethnic and linguistic minorities, children with disabilities, migrant and refugee children, children in conflict with the law, children and young people who do not attend educational institutions, boys and girls living in difficult conditions or in abusive homes already faced significant barriers to participation in education and learning and had less education and social advantages than their peers. The paper presents some considerations from much larger research that analysed the impact of the COVID-19 pandemic on young people.

Introduction: More and more evidence suggests that inflammation is positively associated with age-related cognitive decline and may play a role in the development of dementia. Method: Physiological pathways linking the immune system to the central nervous system are reviewed in this article and studies regarding the association between inflammation and neurocognitive function are reviewed from literature. Results: Recent studies show that midlife inflammation is related to cognitive function and brain morphology. Human studies combining different markers of inflammation, neuroimaging methods and cognitive tests are consistent with studies on animal models which conclude that inflammation contributes to lowering cognitive performance over and above more traditional cardiovascular risk factors such as: hypertension, metabolic factors, smoking and subclinical atherosclerosis. The studies reviewed had limitations by not estimating the impact of multiple factors known to affect circulating levels of inflammatory mediators such as: acute inflammatory disease, psychological stress or physical activity. Conclusions: Circulating markers of inflammation predict future risk of cognitive decline and possibly contribute to the pathophysiology of preclinical neurocognitive decline.
Analysis of future defense policy priorities with AHP
Authors: Kim Dongmin , Bae Kwanpyo
Published: June 2023

Future defense systems cannot maintain the large-scale military force they currently have owing to population decline. Accordingly, the paradigm of military force construction and operation must change from being quantity-to quality-oriented. These changes render the effects of existing defense policies ineffective and highlight that the policies need to be updated. This study analyzes the preferred defense policy in the future defense environment using AHP. This is because efficient allocation and utilization of limited resources and rational decision-making according to policy priorities and in accordance with the paradigm shift in the construction and operation of future defense systems are necessary. The results reveal that the most important policy priority is utilizing science and technology effectively in the future defense. In addition, the policy priorities should be given to policies that focus on the development of weapons systems and acquisition of skilled manpower.

Identification the key strategies of resilience of Ukrainian teachers in the conditions of war
Authors: BANIT Olga , MERZLIAKOVA Olena
Published: June 2023

Background. The problem of individual resilience is becoming especially relevant today, when Ukraine is at war. The issue of preserving physical and mental health of Ukrainians is especially important. No one here was not ready to live and work in war conditions. At the same time, we are able to form an optimal response to these events with the help of resilience. The purpose of the article is to identify the key resilience strategies of Ukrainian teachers in war conditions based on the analysis of the results of the research conducted by the authors. Methods. This research is a part of wider program "Codes of resilience", developed to improve the resilience skills of teachers. The authors use the multidimensional model of overcoming stress and finding internal stability "BasicPh" of Prof. Mooli Lahad to identify the key resilience strategies of Ukrainian teachers in war conditions. This model consists six channels for coping with stress: – belief; A – affect; S – sociability; I – imagination; C – cognition; Ph – physiology. Results. The results of the study showed that the most influential way to overcome stress for teachers is their cognitive settings. Information analysis, critical thinking skills, planning strategies, etc. are the most common ways among teachers to respond to external challenges. The second most influential factor of stress resistance is the worldview of teachers. It turned out that teachers do not actively use their own emotional settings to overcome stress. The same we can say regarding their creative settings. The readiness of teachers to rely on the strength of communities in difficult times (social settings) also needs additional attention and additional research. This factor was the least influential.

The impact of Covid-19, the increasing number of new technologies being applied in education, as well as increasing interest in the metaverse. Closely related to this virtual environment is life in the field of education. This study aims to explain the type of metaverse, the potential and limitations of its educational application. The four metaverse categories emphasize different functions, types, or sets of Metaverse technologies. There are four spectrums of technologies and applications in the metaverse, namely augmentation, simulation, intimate technology, and external technology. The use of augmented reality in health is in the form of virtual clothes so that you can examine parts as human anatomy laboratory simulation. Spinal surgery that applies virtual technology. Utilization in the learning environment is through new forms of social communication space, freer settings for creation and sharing, and additional virtual experiences. The limitations of the metaverse are weaker social relations, and users of the metaverse who do not have an identity, and the abuse of simulation as a representative of student identity in the everyday world. Prediction of changes in daily life patterns as a negative impact of the metaverse. However, the unlimited opportunity to be a form of communication in social life is the hallmark of the metaverse. It is hoped that in the future it is recommended to use the metaverse in education, namely the teacher must conduct a careful analysis beforehand so that students can gain knowledge in the metaverse, the teacher must prepare class designs for students so that they can solve problems and carry out activities cooperatively, adaptively and creatively. Instructional designers and educators need to understand well the type of category and class metaverse.

TD-CARMA: Painless, Accurate, and Scalable Estimates of Gravitational Lens Time Delays with Flexible CARMA Processes
Authors: Meyer Antoine D. , van Dyk David A. , Tak Hyungsuk , Siemiginowska Aneta
Published: June 2023

Cosmological parameters encoding our understanding of the expansion history of the universe can be constrained by the accurate estimation of time delays arising in gravitationally lensed systems. We propose TD-CARMA, a Bayesian method to estimate cosmological time delays by modeling observed and irregularly sampled light curves as realizations of a continuous auto-regressive moving average (CARMA) process. Our model accounts for heteroskedastic measurement errors and microlensing, an additional source of independent extrinsic long-term variability in the source brightness. The semiseparable structure of the CARMA covariance matrix allows for fast and scalable likelihood computation using Gaussian process modeling. We obtain a sample from the joint posterior distribution of the model parameters using a nested sampling approach. This allows for “painless” Bayesian computation, dealing with the expected multimodality of the posterior distribution in a straightforward manner and not requiring the specification of starting values or an initial guess for the time delay, unlike existing methods. In addition, the proposed sampling procedure automatically evaluates the Bayesian evidence, allowing us to perform principled Bayesian model selection. TD-CARMA is parsimonious, and typically includes no more than a dozen unknown parameters. We apply TD-CARMA to six doubly lensed quasars HS2209+1914, SDSS J1001+5027, SDSS J1206+4332, SDSS J1515+1511, SDSS J1455+1447, and SDSS J1349+1227, estimating their time delays as −21.96 ± 1.448, 120.93 ± 1.015, 111.51 ± 1.452, 210.80 ± 2.18, 45.36 ± 1.93, and 432.05 ± 1.950, respectively. These estimates are consistent with those derived in the relevant literature, but are typically two to four times more precise.
A Constraint on the Amount of Hydrogen from the CO Chemistry in Debris Disks
Authors: Iwasaki Kazunari , Kobayashi Hiroshi , Higuchi Aya E. , Aikawa Yuri
Published: June 2023

The faint CO gases in debris disks are easily dissolved into C by UV irradiation, while CO can be reformed via reactions with hydrogen. The abundance ratio of C/CO could thus be a probe of the amount of hydrogen in the debris disks. We conduct radiative transfer calculations with chemical reactions for debris disks. For a typical dust-to-gas mass ratio of debris disks, CO formation proceeds without the involvement of H2 because a small amount of dust grains makes H2 formation inefficient. We find that the CO to C number density ratio depends on a combination of n
H
Z
0.4
χ
−1.1, where n
H is the hydrogen nucleus number density, Z is the metallicity, and χ is the far-UV flux normalized by the Habing flux. Using an analytic formula for the CO number density, we give constraints on the amount of hydrogen and metallicity for debris disks. CO formation is accelerated by excited H2 when either the dust-to-gas mass ratio is increased or the energy barrier of chemisorption of hydrogen on the dust surface is decreased. This acceleration of CO formation occurs only when the shielding effects of CO are insignificant. In shielded regions, the CO fractions are almost independent of the parameters of dust grains.
LIMFAST. I. A Seminumerical Tool for Line Intensity Mapping
Authors: Mas-Ribas Lluís , Sun Guochao , Chang Tzu-Ching , Gonzalez Michael O. , Mebane Richard H.
Published: June 2023

We present LIMFAST, a seminumerical code for simulating high-redshift galaxy formation and cosmic reionization as revealed by multitracer line intensity mapping (LIM) signals. LIMFAST builds upon and extends the 21cmFAST code widely used for 21 cm cosmology by implementing state-of-the-art models of galaxy formation and evolution. The metagalactic radiation background, including the production of various star formation lines, together with the 21 cm line signal tracing the neutral intergalactic medium (IGM), is self-consistently described by photoionization modeling and stellar population synthesis coupled to the galaxy formation model. We introduce basic structure and functionalities of the code, and demonstrate its validity and capabilities by showing broad agreements between the predicted and observed evolution of cosmic star formation, IGM neutral fraction, and metal enrichment. We also present the LIM signals of 21 cm, Lyα, Hα, Hβ, [O ii], and [O iii] lines simulated by LIMFAST, and compare them with results from the literature. We elaborate on how several major aspects of our modeling framework, including models of star formation, chemical enrichment, and photoionization, may impact different LIM observables and thus become testable once applied to observational data. LIMFAST aims at being an efficient and resourceful tool for intensity mapping studies in general, exploring a wide range of scenarios of galaxy evolution and reionization and frequencies over which useful cosmological signals can be measured.
Exoplanet Nodal Precession Induced by Rapidly Rotating Stars: Impacts on Transit Probabilities and Biases
Authors: Stephan Alexander P. , Gaudi B. Scott
Published: June 2023

For the majority of short-period exoplanets transiting massive stars with radiative envelopes, the spin angular momentum of the host star is greater than the planetary orbital angular momentum. In this case, the orbits of the planets will undergo nodal precession, which can significantly impact the probability that the planets transit their parent star. In particular, for some combinations of the spin–orbit angle ψ and the inclination of the stellar spin i
*, all such planets will eventually transit at some point over the duration of their precession period. Thus, as the time over which the sky has been monitored for transiting planets increases, the frequency of planets with detectable transits will increase, potentially leading to biased estimates of exoplanet occurrence rates, especially orbiting more-massive stars. Furthermore, due to the dependence of the precession period on orbital parameters such as spin–orbit misalignment, the observed distributions of such parameters may also be biased. We derive the transit probability of a given exoplanet in the presence of nodal precession induced by a rapidly spinning host star. We find that the effect of nodal precession has already started to become relevant for some short-period planets, i.e., hot Jupiters, orbiting massive stars, by increasing transit probabilities by order of a few percent for such systems within the original Kepler field. We additionally derive simple expressions to describe the time evolution of the impact parameter b for applicable systems, which should aid in future investigations of exoplanet nodal precession and spin–orbit alignment.

Studying open clusters (OCs) may help to provide a comprehensive understanding of the structure and evolution of the Milky Way. Many previous studies have systematically searched for OCs near the solar system within 1.2 kpc or 20° of Galactic latitude. However, few studies have searched for OCs at higher Galactic latitudes and deeper distances. In this study, based on a hybrid unsupervised clustering algorithm (friends-of-friends and pyUPMASK) and a binary classification algorithm (random forest), we extended the search region (i.e., Galactic latitude

and performed a fine-grained blind search for Galactic clusters in Gaia DR3. After crossmatching, the newly discovered cluster candidates are fitted using isochrone fitting to estimate the main physical parameters (i.e., age and metallicity) of these clusters. These cluster candidates were then checked using manual visual inspection. Their statistical properties were also compared with previously exposed cluster catalogs. We found 1179 new clusters with considerable confidence within 5 kpc.
A new species of Siphlonurus Eaton, 1868 (Ephemeroptera, Siphlonuridae) from Yunnan, China
Authors: Yang Kun , Li Xian-Fu , Tong Xiao-Li , Cai Qing-Hua
Published: June 2023

Siphlonurus dongxi Li & Tong, sp. nov. from Shangri-La City, Yunnan Province, China, is described based on egg, nymph, and winged stages. The new species is closely related to S. davidi (Navás, 1932), and can be distinguished by the colour of the imago, the forking point of MP, the penis, posterolateral spines of tergum IX of imagoes, and first abdominal terga nymph, as well as the structure of the egg. The new species and S. davidi have the same morphological and structural characteristics, such as the long cubital area with many intercalaries, cross veins between C, Sc, RA, and RSa1 surrounded with distinct pigments, the strong curvature of vein CuP in the forewing, the broad expansion of the hindwing, the membranous penis lobes fused without teeth, supporting the proposition of a new species complex, the Siphlonurus davidi group. The structures of the penis and the egg of the new species could help understand the origin and evolution of the genus Siphlonurus.

Le trouble de personnalité limite (TPL) est un trouble complexe au sein duquel l’autoagressivité physique et psychique occupent une place importante. L’autoagressivité peut se manifester chez les adolescents et, plus particulièrement, chez ceux qui sont susceptibles de développer un TPL. Vingt-six adolescents provenant d’une école secondaire ont complété des questionnaires autorapportés évaluant l’automutilation, la prise de risque, les traits de personnalité limite en émergence, les symptômes du TPL, l’impulsivité et l’estime de soi. Les résultats révèlent que lorsque l’on contrôle pour l’impulsivité, les liens entre l’automutilation et les traits de personnalité limite en émergence, l’automutilation et les symptômes associés au TPL, la prise de risque et les traits de personnalité limite en émergence ne perdurent pas. De plus, il n’y a pas de lien entre les symptômes du TPL et la prise de risque. Enfin, la sévérité des symptômes du TPL prédit de plus fortes manifestations d’autoagressivité psychique. Il n’y a pas de lien entre l’émergence de traits de personnalité limite et l’autoagressivité psychique. Les limites et forces de l’étude sont discutées.
Le Parrain : sociologie du don, rhétorique du Don et ethnographie du migrant
Authors: Provenzano François
Published: June 2023

L’article prend pour objet le personnage du Parrain rendu célèbre par le roman éponyme de Mario Puzo, puis par la saga cinématographique de Francis Ford Coppola. Ce personnage est resitué dans les différentes lignes narratives qui structurent sa mise en fiction (histoire sociale, histoire familiale, récit d’initiation, tragédie amoureuse), pour ensuite être envisagé au prisme de la théorie du don de Marcel Mauss. La forme particulière d’économie sociale et affective illustrée par le Parrain permet d’éclairer la spécificité du don mafieux. L’article s’attache ensuite aux codes de la représentation verbale du personnage, qui soutiennent son caractère ethnicisé. Dans son dernier mouvement, l’article s’interroge alors sur ce que la qualité d’émigré sicilien apporte à ce personnage et à la compréhension des dynamiques sociales dans lesquelles il évolue.
Bilan et perspectives de la décentralisation de l’action sociale et médico-sociale
Authors: Jacquey Bénédicte
Published: June 2023

La décentralisation a entraîné l’affirmation du département-providence. L’aide sociale locale s’est fortement développée mais reste fragilisée par un déficit de gouvernance et un financement inadéquat. Elle doit aussi faire face à une forme de désarmement intellectuel de l’État sur la question sociale.
Des instances sociales locales de consultation, concertation et coordination à repenser ?
Authors: Rabiller Stéphanie
Published: June 2023

Aujourd’hui, la démarche « aller-vers » comme la logique de parcours témoignent d’un changement de paradigme de l’intervention publique. Il ne s’agit plus d’imposer un cadre préétabli, mais de retenir la singularité de la personne ou d’un groupe cible à l’échelle locale pour proposer un accompagnement adapté partant des attentes et des besoins. Cette approche territoriale et populationnelle induit une organisation horizontale de l’action publique et moins de distanciation avec les personnes accompagnées. D’où une prolifération de lieux de consultation, concertation et coordination ouverts à tous les acteurs du champ des politiques sociales, représentants d’usagers compris. L’étude vise à explorer cette collaboration élargie et propose des pistes de réflexion pour faire de ces espaces des lieux d’intérêts communs.
Global existence and stability of temporal periodic solution to non-isentropic compressible Euler equations with a source term
Authors: Ma Shuyue , Sun Jiawei , Yu Huimin
Published: June 2023

In this paper, the 1-D compressible non-isentropic Euler equations with the source term $ \beta\rho|u|^ \alpha u $ in a bounded domain are considered. First, we study the existence of steady flows which can keep the upstream supersonic or subsonic state. Then, by wave decomposition and uniform prior estimations, we prove the global existence and stability of smooth solutions under small perturbations around the steady supersonic flow. Moreover, we get that the smooth supersonic solution is a temporal periodic solution with the same period as the boundary, after a certain start-up time, once the boundary conditions are temporal periodic.

Published: June 2023

In this paper, we study the finite volume element method of bilinear parabolic optimal control problem. We will use the optimize-then-discretize approach to obtain the semi-discrete finite volume element scheme for the optimal control problem. Under some reasonable assumptions, we derive the optimal order error estimates in $ L^2(J; L^2) $ and $ L^\infty(J; L^2) $-norm. We use the backward Euler method for the discretization of time to get fully discrete finite volume element scheme for the optimal control problem, and obtain some error estimates. The approximate order for the state, costate and control variables is $ O(h^{3/2}+\triangle t) $ in the sense of $ L^2(J; L^2) $ and $ L^\infty(J; L^2) $-norm. Finally, a numerical experiment is presented to test these theoretical results.

Outbreaks of infectious diseases pose significant threats to human life, and countries around the world need to implement more precise prevention and control measures to contain the spread of viruses. In this study, we propose a spatial-temporal diffusion model of infectious diseases under a discrete grid, based on the time series prediction of infectious diseases, to model the diffusion process of viruses in population. This model uses the estimated outbreak origin as the center of transmission, employing a tree-like structure of daily human travel to generalize the process of viral spread within the population. By incorporating diverse data, it simulates the congregation of people, thus quantifying the flow weights between grids for population movement. The model is validated with some Chinese cities with COVID-19 outbreaks, and the results show that the outbreak point estimation method could better estimate the virus transmission center of the epidemic. The estimated location of the outbreak point in Xi'an was only 0.965 km different from the actual one, and the results were more satisfactory. The spatiotemporal diffusion model for infectious diseases simulates daily newly infected areas, which effectively cover the actual patient infection zones on the same day. During the mid-stage of viral transmission, the coverage rate can increase to over 90%, compared to related research, this method has improved simulation accuracy by approximately 18%. This study can provide technical support for epidemic prevention and control, and assist decision-makers in developing more scientific and efficient epidemic prevention and control policies.
