Authors: Mulyani Noris Hadi Sri , Prasetya Hanung , Murti Bhisma
Published: January 2024

Background: Postpartum depression is a form of depression that occurs during the puerperium with specific symptoms that appear 4-6 weeks after delivery and can last for months, affecting the happiness and emotional relationship between mother and child. This study aims to analyze the effect and estimate the size of the effect of family support, family income levels and domestic violence on the incidence of depression among postpartum women with a meta-analysis.

Subject and Method: The meta-analysis was carried out using the PRISMA flowchart and the PICO model. Population: postpartum mothers. Intervention: strong family support, high family income levels and domestic violence. Comparison: weak family support, low family income level and no domestic violence. Outcome: postpartum depression. The online databases used are Google Scholar, Hindawi, PubMed, Science Direct, Scopus, and ResearchGate. There were 18 cross-sectional studies published in 2013-2023 that met the inclusion criteria. Analysis was performed with RevMan 5.3.

Results: Meta-analysis of 18 articles with cross-sectional research designs from different countries, with a sample size of 29,638 research subjects. The results of the meta-analysis show that there is an effect of family support on the risk of postpartum depression. Mothers who received high family support had a risk of experiencing postpartum depression by 0.69 times lower compared to those who received low family support (aOR= 0.69; 95% CI= 0.38 to 1.27; p=0.240). Mothers with high family income levels have a risk of experiencing postpartum depression by 0.50 times lower compared to low family income levels (aOR= 0.50; 95% CI= 0.28 to 0.90; p=0.020). Mothers who experience domestic violence have a risk of postpartum depression by 4.20 times higher compared to those who do not experience domestic violence and the relationship is statistically significant (aOR=4.20; CI 95% =2.56 hingga 6.88; p<0.001).

Conclusion: Strong family support and high levels of family income reduce the risk of postpartum depression. Meanwhile, domestic violence increases the risk of postpartum depression.

Keywords: Postpartum Depression, Family suport, Family income, Domestic violence.

The Validity of Transmission of Ijazah Hadith Musalsal Through Social Media Salafi Ulema Perspective: A Study of Sanad Connectedness (Studies al-Tahammul wa al-Adā')
Authors: Su’aidi Hasan , Marwan bin Mohammad Amin  , M. Ikmal
Published: January 2024

The focus of this paper is on the quality and understanding of the hadith in the DSNMUI Fatwa No. 108 of 2016 concerning halal tourism. The use of hadith as a source of fatwas is important, especially with regard to the legality of an Islamic perspective. However, like a fatwa, this hadith is not followed by an explanation regarding the quality of the hadith and how to understand the meaning that comes from the hadith so that it can be used as a source of fatwa. On the one hand, it must be ensured that the hadith can be accounted for as originating in the Prophet, both in sanad and matan so that its use has high validity. In addition, the existence of hadith when it was born has a distance in time and space that is quite far so whether reinterpretation is needed or not. To answer the problem, this study uses library research by applying the method of criticizing sanad, matan and ma'anil hadith. In the data analysis using descriptiveanalytical techniques.This paper shows that there are two hadiths used by DSN-MUI. The first hadith narrated by Imam Ahmad bin Hanbal is of da'if quality because there are two narrators who are considered weak, namely Ibn Lahi'ah and Darraj bin Sam'an. Meanwhile, the second hadith, which was narrated by Imam al-Bukhari and Imam Muslim, is of valid quality. The content of the meanings of the two hadiths used by the DSN-MUI is a recommendation for travel that is not only aimed at entertainment or a healthy body, but also travel compassion and increase obedience.
A study of the correlation between magnesium and ferritin levels and the severity of the disease and sleep quality in restless legs syndrome
Authors: Üstün Özek Sibel
Published: January 2024

Background/Aim: Restless legs syndrome (RLS) is a chronic neurological disease that impairs sleep quality, causes emotional stress and affects daily activities. While the association between disease severity and low iron and ferritin levels is known, the magnesium (Mg) results are contradictory. This study aimed to investigate the influence of low Mg and ferritin levels on the severity of the disease and sleep quality.
Methods: A case-control study included 50 RLS patients aged 18–78 years and 50 healthy control patients. Mg and ferritin levels were measured, considering values below <1.8 mg/dL and 75 ng/mL as low. Both groups completed the International Restless Legs Syndrome Severity Rating Scale (IRLSSG) to assess the severity of RLS, as well as the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) to evaluate subjective sleep quality.
Results: The mean age of RLS patients and the control group was 47.06 (13.35) years and 43.30 (15.43) years, respectively (P=0.196). The RLS patients had an IRLSSG score of 25.16 (6.85). The PSQI total scores, subscale scores, and ESS scores of RLS patients were significantly higher than those of the control group. However, no significant difference was observed in the IRLSSG score, PSQI, and ESS scores based on Mg and ferritin levels. Sleep latency was found to be shorter in individuals with Mg deficiency.
Conclusion: Sleep disorders are prevalent among RLS patients. No correlation was found between Mg and ferritin levels and disease severity or sleep disorders. Furthermore, Mg deficiency did not appear to exacerbate the IRLSSG score or sleep disorder scores.
Exploring the impact of directionality on disfluencies in simultaneous interpreting
Authors: Gierszal Sylwia , Łyda Andrzej
Published: January 2024

This paper focusses on the concept of directionality in interpreting. The main aim of this study is to investigate four types of disfluencies in simultaneous interpreting performed by students and the impact of pausal phenomenon on directionality. Disfluencies being inseparable element of speech are the factor that has a substantial influence on interpreting process including directionality. The participants in this study were 12 advanced interpreting students who interpreted simultaneously two texts from A language into B language and two texts from B language into A language. Their outputs were later analysed taking into consideration four types of disfluencies and verified how they influence directionality. This study offers some insights into occurrences of disfluencies. Research findings show that students display tendency to produce more disfluencies while interpreting into A language. In addition, the obtained results highlight the necessity to focus not only on fluency but also on disfluencies while interpreting training to improve quality in simultaneous interpreting in both directions.
Conodont-based stratigraphy in the Devonian of the Serre Massif (southern Italy)
Authors: Navas-Parejo Pilar , Somma Roberta , Canero Rosario Rodriguez , Martin-Algarra Augustin , Perrone Vincenzo
Published: January 2024

The results of litho- and biostratigraphic studies of three sections measured in weakly metamorphosed Famennian carbonate successions of the Stilo Unit in the Serre Massif (Calabria, southern Italy), together with recently published stratigraphic data related to other Devonian carbonates from the same area, allow definition of three formations: Assi Formation, San Giovanni Formation, and Ponte Vina Formation. The Assi Formation consists of grey, slightly nodular limestones alternating with thin-bedded calcareous slates; the type section has recently been dated, by conodonts, as Early-Middle? Devonian. The San Giovanni Formation consists of reddish nodular limestones, rich in greyish matrix, and contains Famennian (Late Devonian) conodonts. The Ponte Vina Formation is mainly composed of metacarbonates recently dated as Late Devonian by means of conodonts. These new data suggest correlation with nearby domains belonging to the Sicilian Longi-Taormina Unit or other better-known Paleozoic sequences in the western Mediterranean area, such as the Alps and the Betic and Rifian chains, and indicate that the studied succession developed in a sedimentary basin along the northern Gondwana margin during the Devonian.

Currently the North American Stratigraphic Code, (NACSN 2005, Article 37) sets restrictions on the use of the term “complex” for lithodemic units. With exceptions for “volcanic complex” and “structural complex,” a complex must consist of more than one genetic class of rock (i.e., sedimentary, igneous or metamorphic). Thus, the use of the term “complex” to describe masses of intrusive rocks is not allowed. Asimilar restriction is also included in a recent British Geological Survey proposal for using lithodemic units to classify igneous rocks (Gillespie et al. 2008).Currently the North American Stratigraphic Code, (NACSN 2005, Article 37) sets restrictions on the use of the term “complex” for lithodemic units.

Stratigraphy and paleogeographic significance of a Late Pennsylvanian to Early Permian channeled slope sequence in the Darwin Basin, southern Darwin Hills, east-central California
Authors: Stevens Calvin H. , Stone Paul , Magginetti Robert T. , Ritter Scott M.
Published: January 2024

The complex stratigraphy of late Paleozoic rocks in the southern Darwin Hills consists of regionally extensive Mississippian and Early to Middle Pennsylvanian rocks overlain by latest Pennsylvanian to Early Permian rocks, herein called the Darwin Hills sequence. Deposition of this latter sequence marked the beginning of the Darwin Basin. In Mississippian time, a carbonate platform prograded westward over slightly older slope deposits. In the Late Mississippian this platform was exposed to erosion and siliciclastic sediments were deposited. In Early to Middle Pennsylvanian time the area subsided, forming a west-facing ramp that was subjected to deformation and erosion in Middle or early Late Pennsylvanian time. Later this area was tilted westward and deep-water sediments were deposited on this slope. In latest Pennsylvanian to earliest Permian time, a major channel was cut through the older Pennsylvanian rocks and into the Upper Mississippian strata. This channel was gradually filled with increasingly finer grained, deep-water sediment as the area evolved into a basin floor by Early Permian (Sakmarian) time. Expansion of the Darwin Basin in Artinskian time led to a second phase of deposition represented by strata of the regionally extensive Darwin Canyon Formation. The geology in this small area thus documents tectonic events occurring during the early development of the Darwin Basin.

ANALYSIS OF TRAINING AND SYSTEMS FOR FRENCH TEACHERS IN SENEGAL
Authors: LY Thierno
Published: January 2024

The training of future secondary school teachers of french has always played a very important role in education policy in Senegal. Indeed, among other objectives, it is essentially based on the acquisition of knowledge related to the subject of french, pedagogical and didactic skills, and a perfect knowledge of the content of secondary school curricula. This raises the issue of content and practical approaches in teacher training. Thus, the question is what curriculum content, what pedagogical and didactic tools and approaches are used to the training practices of future french teachers in Senegal. To better answer these questions, we first checked the content and arrangements for training future teachers of french. The initial results show that the content, tools and teaching approaches used in training practices are not always in line with those officially recommended and are not fully stabilised and applied in didactic situations.

Published: January 2024

A precipitação no estado de Alagoas - Brasil, apresenta um comportamento espacial e temporal extremamente irregular, o que possibilita a análise do comportamento hidrológico e da variabilidade pluviométrica da região. Para melhor compreender a variabilidade das chuvas em Alagoas entre 2000 a 2022, foram utilizados dados de precipitação da rede orbital GPM-IMERG (Global Precipitation Measurement) e de pluviômetros, bem como o Índice de Anomalia de Precipitação (IAC) e o Índice de Precipitação Concentrada (IPC), para entender a dinâmica de eventos anormais de chuvas e suas formas de variabilidades. Observou-se que as chuvas em Alagoas exibem um padrão sazonal, com precipitações anuais variando aproximadamente entre 500 mm e 1.900 mm, evidenciado pelos valores do IAC, que oscilaram entre as categorias de "extremamente chuvoso" e "extremamente seco". Por outro lado, o IPC anual mostrou alta estabilidade, sendo geralmente classificado como "Baixa irregularidade", com exceção apenas em 2009. Quanto à capacidade de detecção dos dados do GPM-IMERG, os resultados evidenciaram que nos meses chuvosos, os erros espaciais foram discrepantes, permanecendo abaixo de 10 mm. No entanto, nos meses com menor volume de chuvas, os erros foram significativos, atingindo cerca de 30 mm. Esta pesquisa demonstrou a utilidade dos dados do GPM-IMERG na análise da precipitação em vastas áreas, o que pode subsidiar a proposição de medidas para reduzir ou mitigar os conflitos decorrentes da escassez de água, além de identificar alternativas para melhorar o acesso da população aos recursos hídricos.
Impacts of changes in land cover and land use on the hydrological cycle of the Tapuio River sub-basin/AL
Authors: Silva Leal Rafaella Silva Leal , Almeida Nadjacleia Vilar , Silva Milena Dutra da
Published: January 2024

The climate forecasts in the IPCC latest assessment report (AR6) point to rising global temperatures. The northeastern semi-arid region is characterized by extreme droughts and intense rainfall, indicating a scenario of climatic extremes. Climate change directly affects the hydrological cycle because it modifies the entire dynamics of the system, causing major environmental impacts in river basins. These impacts are intensified by changes in land cover, favoring modifications to landscapes through alternative land uses. In this sense, the study arises from the need to analyze how changes in land use and cover can affect the dynamics of the hydrological cycle in the Tapuio river sub-basin from a space-time perspective. The region was chosen based on the observation of data collected during the IV scientific expedition to the Lower São Francisco. For the study, a simulation was carried out using the SWAT tool with land use and land cover data (2000 and 2020), soil type, slope and climate data (precipitation and temperature). The simulation generated the delimitation of 24 microbasins and 553 HRUs for the year 2000 and 662 for the year 2020, as well as visualizing the main parameters of the hydrological cycle. It was found that there was a significant increase in surface runoff of 4%, sediment production of 9% and a reduction in potential evapotranspiration of 0.42%. The conclusive analyses indicate that the conversion of the savannah formation use classes for pasture and temporary crops would have been the main cause of the changes in the hydrological cycle in the Tapuio river sub-basin.

Innovative telemedicine technology usage in rare diseases management in primary care in a COVID-19 pandemic era: Lessons learnt and recommendations for future practice
Authors: Olowu Adekunle
Published: January 2024

COVID-19 affected routine healthcare significantly and impaired the capability of healthcare organizations to deliver quality healthcare to achieve expected patient outcomes, including the care of patients with rare diseases. The rationale for this review is to highlight the important contribution of telemedicine technology to improving care quality of patients with rare diseases in a pandemic era. Aims and Objective: To explore the role and impact of telemedicine digital technology usage and user satisfaction in patients with rare diseases in the last two years since the COVID-19 pandemic. Methodology: An electronic database search was conducted using the PRISMA guide with search terms ‘telemedicine’ and ‘rare diseases’ in the last 2 years since the COVID-19 pandemic. The final search identified about 10 papers after screening, applying the exclusion criteria and sorting for eligibility and relevance. Results: Of the 10 papers reviewed, 6 were research articles while 4 were review articles. For the research papers there were 5239 participants or responders in total, with 1476 (28.2%) patients, 50 (0.01%) carers and 3713 (70.9%) clinicians and workers. The average age recorded by 4 of the research papers was 43.4 years while one paper particularly emphasized that telemedicine digital technology was used preferably by clinicians below 50 years of age. 52.5% of Clinician and Worker participants in 2 Studies were Male while 47.5% were Female, while only 22% of patient participants were Male, with 78% being Female. One paper recorded the proportion of patients who used telemedicine as 22.8 %, a second recorded the highest proportion of clinicians’ telemedicine usage as 59.8%, a third paper concluded the highest number of carers who were satisfied with telemedicine usage was 90%, with 58% also supporting its usage and a fourth recorded that 86% of patients were satisfied with its usage. However, another paper recorded that 26% of clinicians (psychiatrists) were not keen to use telemedicine. Conclusion: This review concludes that there is some evidence that telemedicine digital technology is a viable option and can be a long-term solution to primary care patients’ access to quality care in the post-pandemic era, including patients with rare diseases. International collaboration of clinicians via electronic or digital platforms will enhance quality of care, especially targeted to younger male physicians below the age of 50. Guidelines and protocol for its use within governmental laws and legal boundaries need to be strictly followed to ensure patient safety, reduce waiting times and achieve positive patient outcomes.

Authors: De Oliveira Tailize , Girardi Alessandro , De Aguirre Paulo César , Severo Lucas
Published: January 2024

Batteryless devices are essential for hard-to-reach applications such as implantable biomedical devices.Powering such devices is a difficult task, and energy harvesting from the environment is mandatory. Among the power sources available in urban areas, RF signals stand out. However, the RF power at the receiving antenna is not constant, and energy-harvesting circuits should provide a stable DC output voltage. In this paper, we present an RF energy harvestingbased power management system that provides a stable 0.4-V DC supply voltage to power low-voltage systems. A closed-loop impedance matching tuning system is used to automatically regulate the system DC output voltage by tuning the input impedance matching network. The proposed circuit is implemented at schematic level in a 65-nm standard CMOS process.The entire system power efficiency (PCE) is 48.28% at the input power level of -14.92 dBm. The proposed solution is demonstrated for powering low-voltage devices with a regulated output voltage of 0.4 V and 16 uW resistive load.

Authors: Isal Muhammad Aryanang , Sidik Rahmat Maulana
Published: January 2024

Penelitian ini bertujuan untuk menganalisis dampak inovasi bisnis Social Commerce bagi pelaku UMKM, keberadaan Tiktok Shop sebagai Social Commerce sudah lama diantisipasi oleh pemerintah luar negeri, sedangkan pemerintah Indonesia juga sudah mengeluarkan kebijakan larangan praktek monopoli melalui Social Commerce, sebagaimana diatur dalam Permendag 31/2023. Globalisasi dan kemajuan teknologi menjadi tak terelakkan dalam mengubah perilaku bisnis di Indonesia, namun jangan sampai hal tersebut justru dapat membunuh pelaku usaha kecil (UMKM). Sehingga peran pemerintah untuk menyusun regulasi menjadi penting untuk melindungi kelangsungan UMKM. Penelitian ini menggunakan pendekatan penelitian Socio-Legal Studies yaitu melakukan analisis hukum doktriner dan studi interdisipliner dengan melakukan analisis wacana kritis terhadap statement dari aktor-aktor yang berkelindan dalam kebijakan Social Commerce. Dalam penelitian ini dapat disimpulkan bahwa perlindungan UMKM melalui Permendag 31/2023 tidaklah cukup, praktek monopoli bisnis tidak hanya terjadi pada Social Commerce saja melainkan juga terjadi di sektor E-commerce konvensional sehingga perlu adanya komitmen khusus untuk mengawasi Social Commerce dan E-commerce. Disisi lain pemerintah juga perlu meninjau perjanjian internasional dalam hal ini seperti ACFTA agar dapat sesuai dengan kebutuhan UMKM dan dapat menghindari praktek predatory pricing.

Stability Analysis of Nonlinear Dynamic Systems Using the Lyapunov Method Approach
Authors: Peranginangin Andreas Perdamenta
Published: January 2024

A new approach to the stability analysis of homogeneous nonlinear systems is proposed, based on the concept of candidate Lyapunovfunctions, where the focus is not on the positive definiteness of the candidate Lyapunovfunctions, but on the negative definiteness of their derivatives. After having ensured the negative definiteness of the derivative function, on the basis of the sign assignment of the primitive function, the stability of the equilibrium is analyzed, where the necessary and sufficient conditions are declared at the same time. The selection of the tendency of the Lyapunov candidate function is primarily performed in the form of a linear combination of some simple functions. The unknown coefficients in the structure of the candidate function are computed based on the negative definiteness of the derivative function. Then, using these coefficients in Lyapunov function, sign of primitive function in state space is argued. Thus, the stability/instability of the equilibrium point can be deduced from the triple sign settings of the candidate function. Furthermore, in the process of negative definiteness of the derivative function, the coefficients are obtained using two independent methods. The proposed theoretical results are supported and their effectiveness is demonstrated by numerical simulations.
