TAMBAHAN BIAYA PADA TRANSAKSI PEMBAYARAN SISTEM PAYLATER DI MAKETPLACE DALAM PERSPEKTIF AKAD MUAMALAH KONTEMPORER
Authors: Bariroh Muflihatul
Published: October 2024

This article aims to examine in depth and try to emphasize understanding regarding the emergence of a discourse and debate among the Muslim community regarding the legality of the paylater practice which has raised doubts among Muslims because several previous literatures stated that the use of the pay later method is prohibited because of the additional costs of the total principal expenditure which is indicated contains usury. Paylater itself or the pay later system is one of the new digital payment systems in today's marketplace without using a credit card. Paylater offers convenience facilities for platform users in shopping so they can make payments at a later date. This research method is a qualitative type which is prescriptive descriptive using an instrumental case study type approach. This approach is used to express a deep and detailed picture of a situation or object, where the author aims at a deep understanding of an issue or reformulating a theoretical explanation. The research results show that additional costs in the paylater payment system by platform users have not automatically considered usury. Through in-depth understanding, with the option of using a taqsith sale and purchase contract and/or a kafalah bil ujrah contract, the addition of the paylater payment system can be justified. These additional costs can act as a margin in buying and selling or can act as a fee or reward in a kafalah bil ujrah contract, such as fees in sharia card practices.
KHILAFAH DALAM PEMIKIRAN KH AHMAD BAHAUDDIN NURSALIM
Authors: Ula Siti Khoirotul
Published: October 2024

This article explains the views of KH Ahmad Bahauddin Nursalim on “the khilafah” as prescribed in Surat An-Nur verse 55. The method used in this research is a qualitative research with a content analysis approach and using al-Ghazali's philosophy for analysing. This research analyzes the explanation of KH Ahmad Bahauddin Nursalim about the khilafah as presented in the video containing his study of the Book of Tafsir Jalalain. It was found in You Tube account entitled “Ngaji Gus Baha Jogja” with the theme “Makna Khilafah” in a video that lasts 1 hour, 25 minutes, and 35 seconds. This research found that KH Ahmad Bahauddin Nursalim believes that the promise of Allah about the realization of Islamic khilafah for the believers is likely to be realized in the future, not today. Hence, he advised those who had knowledge to be patient and not to fail in interpreting the verses of the Qur'an. Khilafah, for the time being, cannot be applied in Indonesia because of its highly multi-religious and multicultural demographic conditions. If the khilafah is applied, there is potential chaos that threatens the sovereignty of the country. The view of KH Ahmad Bahauddin Nursalim is a moderate one in the very harsh rejection of khilafah and not out of the original meaning of the text of Surat an-Nur verse 55. If reviewed from the theory of division categories of maslahat according to al-Ghazali in understanding the text about this khilafah, the view of KH Ahmad Bahauddin Nursalim that “khilafah is irrelevant for today's time” can be categorized as maslahat dzaruriyat; otherwise, then there will raise chaos. For further research, the author suggests that the view of Khilafah by KH Ahmad Bahauddin Nursalim can be compared with the views of other moderate scholars.
QAWL QADIM AND QAWL JADID (Study Of Ash-Shafi’i’s Legal Synthesis Model on Zakat)
Authors: Monady Hanief , Rahmi Nispan
Published: October 2024

One proof of the unique freedom of legal thought in the early days of Islam in the first Hijriah/7 AD and second Hijriah/8 AD centuries, was the emergence of a large collection of legal views that grew in various centers in Iraq, Hijaz, Syria and Egypt. One of them is the moderate Shafi'i school founded by Muhammad bin Idris Asy-Syafi'i. This research aims to describe the contextualization of Ash-Shafi'i legal events and thoughts regarding Qawl Qadim and Qawl Jadid, as well as to synthesize Ash-Shafi'i law when faced with different social conditions in society, while many legal cases have emerged that require solutions. law immediately. This research is in the form of qualitative descriptive research, using a literature review. The research objects of this research are writings and texts that describe and are related to this research using content analysis data processing methods from these writings. From the results of the analysis it was found that Ash-Shafi'i in carrying out legal synthesis, both in the context of Qawl Qadim and Qawl Jadid, did not only adhere to historical texts, but also used ra'yu, both of which were used in a balanced and parallel manner.

Hanswilkeite, KFe3+S2, is a new potassium-rich natural sulfide discovered in the pyrometamorphic suite of the Hatrurim Formation, southern Negev Desert, Dead Sea basin, Israel. The mineral occurs in sulfide-calcite assemblages confined to black-colored calcite-spurrite marbles. It forms single-crystal grains up to 1 mm in size, isometric to lath-like, often intergrown with a less-common rasvumite, KFe2S3. Associated minerals include srebrodolskite, tilleyite, fluormayenite, cuspidine, fluorapatite, oldhamite, pyrite, and andradite. Macroscopically, hanswilkeite has a deep-purple color, dull metallic luster and brown-black streak. The Mohs’ hardness is 2. Moderate cleavage was observed along the c-axis. The calculated density is 2.654 g·cm-3. The Raman spectrum contains the following bands: 379, 357, 289, 236, 167, 131 and 124 cm-1. In reflected light, the mineral has very strong pleochroism from yellow-pink to dark-grey. Anisotropy is very strong, ∆R589 = 69 %. Reflectance values for COM required wavelengths measured in air, Rmax/Rmin (λ, nm) (%): 16.0/9.2 (470); 19.6/9.3 (546); 18.5/9.0 (589); 32.0/9.3 (650). Chemical composition (electron microprobe, average of 6 points, wt. %): K 23.78, Ca 0.44, Fe 34.75, Mn 0.60, Zn 0.47, S 39.46, Total 99.5, that corresponds to empirical formula (K0.98Ca0.02)1.00(Fe1.00Mn0.02Zn0.01)1.03S1.98 (Σ = 4 apfu) or ideally KFe3+S2. Single-crystal X-ray diffraction study shows that the mineral is monoclinic, space group C2/c (#15), with unit-cell parameters a = 7.0914(5), b = 11.3154(5), c = 5.3992(3) Å, β = 113.244(7)°, V = 398.08(4) Å3 and Z = 4. Strongest lines of X-ray powder diffraction pattern [d in Å(I)(hkl)]: 5.68(100)(020,110); 3.270(31)(130); 3.227(29)(111); 2.921(45)(–221); 2.510(12)(131); 2.198(12)(–132); 1.880(10)(330). The crystal structure has been solved and refined to R1 = 0.038 for 454 unique observed reflections [I ≥ 2σ(I)]. The structure consists of infinite chains of edge-sharing tetrahedra [FeS4]– centered with Fe3+; the sulfide chains are linked by K+ ions. Hanswilkeite is the third discovered dithioferrate mineral: a sulfosalt that contains [FeS2]– anion with iron in Fe3+ state. Other known natural dithioferrates are erdite, NaFeS2·2H2O, and raguinite, TlFeS2. Hanswilkeite has a synthetic counterpart and a group of related synthetic sulfides and selenides, well studied due to specific electrical and magnetic properties owed to their quasi-one-dimensional structures. The mineral can be considered as an indicator of an extreme potassium-rich environment superimposed onto anhydrous and oxidizing formation conditions. The association with oldhamite is herein discussed in view of super-reduced conditions previously supposed for oldhamite geosynthesis.

Published: October 2024

AbstractThe purpose of this writing is to promote the commandment of loving others as the theological foundation underlying the praxis of religious moderation. The method used is library research, with a descriptive analysis approach to various reference sources. This research resulted in findings on the importance of living the commandment “love your neighbor as yourself” and making it a lifestyle or lifestyle (daily action). This study confirms that the implementation of religious moderation can begin with a correct theological understanding of moderation, because a correct understanding of the theological basis of religious moderation will encourage moderate behavior. Christianity teaches the law of love which emphasizes the balance of people’s relationships with God and others. Loving God is proven by loving other to the same standard as loving himself. This balance is the basic principle of religious moderation. The teaching of love is also emphasized in the golden rules of love with the principle of solidarity.
AbstrakTujuan penulisan ini adalah untuk mengedepankan perintah mengasihi sesama sebagai landasan teologis yang melandasi praksis moderasi beragama. Metode yang digunakan dalam kajian ini adalah penelitian kepustakaan, dengan pendekatan analisis deskriptif terhadap berbagai sumber referensi. Penelitian ini menghasilkan temuan tentang pentingnya menjalankan perintah “mengasihhi sesama seperti diri sendiri” dan menjadikannya sebagai gaya hidup atau lifestyle (tindakan sehari-hari). Kajian ini menegaskan bahwa penerapan moderasi beragama dapat dimulai dari pemahaman teologis moderasi beragama dengan benar, sebab pemahaman yang benar terhadap landasan teologis moderasi beragama akan mendorong perilaku moderat. Agama Kristen mengajarkan hukum kasih yang menekankan pada keseimbangan hubungan manusia dengan Tuhan dan sesama. Mencintai Tuhan dibuktikan dengan mencintai sesama sama seperti mencintai diri sendiri. Keseimbangan inilah yang menjadiprinsip dasar moderasi beragama. Ajaran cinta juga ditekankan pada hukum emas dengan prinsip solidaritas.
Quantum phases of hardcore bosons with repulsive dipolar density-density interactions on two-dimensional lattices
Authors: Koziol Jan Alexander , Morigi Giovanna , Schmidt Kai Phillip
Published: October 2024

We analyse the ground-state quantum phase diagram of hardcore Bosons interacting with repulsive dipolar potentials. The bosons dynamics is described by the extended-Bose-Hubbard Hamiltonian on a two-dimensional lattice. The ground state results from the interplay between the lattice geometry and the long-range interactions, which we account for by means of a classical spin mean-field approach limited by the size of the considered unit cells. This extended classical spin mean-field theory accounts for the long-range density-density interaction without truncation. We consider three different lattice geometries: square, honeycomb, and triangular. In the limit of zero hopping the ground state is always a devil’s staircase of solid (gapped) phases. Such crystalline phases with broken translational symmetry are robust with respect to finite hopping amplitudes. At intermediate hopping amplitudes, these gapped phases melt, giving rise to various lattice supersolid phases, which can have exotic features with multiple sublattice densities. At sufficiently large hoppings the ground state is a superfluid. The stability of phases predicted by our approach is gauged by comparison to the known quantum phase diagrams of the Bose-Hubbard model with nearest-neighbour interactions as well as quantum Monte Carlo simulations for the dipolar case on the square and triangular lattice. Our results are of immediate relevance for experimental realisations of self-organised crystalline ordering patterns in analogue quantum simulators, e.g., with ultracold dipolar atoms in an optical lattice.
Comparison of SEMG-Based Hand Gesture Classifiers
Authors: DeLello Guilherme , Chaves Gabriel , Caldeira Juliano , Lima Markus
Published: October 2024

Machine learning techniques have shown success in classifying hand gestures. As the prevalence of prosthetic devices continues to rise, the adoption of non-invasive technologies, such as surface electromyography (sEMG), becomes paramount. This study systematically assesses the isolated influence of classification algorithms within hand gesture recognition (HGR) systems using sEMG data and dynamic time warping (DTW) based features. This approach effectively handles temporal variations in sEMG signals by leveraging DTW, ensuring input features are invariant to gesture speed. Six supervised learning classifiers were evaluated: the multilayer perceptron, support vector machine, logistic regression, linear discriminant analysis, k-nearest neighbors, and decision tree. Cross-validation was employed to fine-tune the segmentation hyperparameters, significantly improving results. To ensure reproducibility, the source code has been made available, the proposed system design has been detailed, and the evaluation protocols have been described. Our findings indicate that logistic regression outperformed other classifiers in this setup, achieving 95.2% accuracy in classifying six hand movements from ten healthy individuals, representing a 1.6% improvement over the best previously reported performance using the same publicly available dataset. Future research will assess the proposed HGR system’s generalization capability on larger datasets suitable for training more complex classifiers, including deep learning models.
Conversion of waste paper sludge into magnetic biochar for activation of peroxydisulfate for tetracycline removal
Authors: Zhang Xin , Zhang Hongtao , Cai Shuhan , Hu Zehong
Published: October 2024

The Fe2+-peroxydisulfate (PDS) process is an effective method to enhance paper sludge dewaterability. However, the generated waste of iron-rich sludge cake needs to be disposed of properly. Converting sludge cake into magnetic biochar catalysts can help to shorten its environmental risks, recover resources, and reduce catalyst costs. In this work, the magnetic sludge biochar (Fe-SBC) was prepared and applied as a PDS activator to remove tetracycline (TC). Results showed that the Fe-SBC pyrolyzed at 600 °C presented excellent catalytic activity for PDS to degrade TC (rate of 74.89%) under the optimum conditions (intrinsic pH, 10 mM PDS, 0.5 g/L Fe-SBC, and 50 mg/L TC). It was found for the first time that the addition sequences of the biochar catalyst and PDS were insignificant on TC removal. Furthermore, the TC removal mechanism was proposed to be free radicals (·OH, SO4·−, and O2−·) and non-radical (1O2) pathways working together for TC removal, for which 1O2 was dominated. In addition, coexisting ions (Cl− and CO32−) had an inhibitory effect on TC degradation. This work will provide a new recycling approach for waste paper sludge in wastewater treatment.
Implementation of an Automated System Using Machine Learning Models to Accelerate the Process of In Silico Identification of Small Molecules As Drug Candidates
Authors: Sevimoglu Tuba
Published: October 2024

Drugs are commonly utilized to diagnose, cure, or prevent the occurrence of
diseases, as well as to restore, alter, or change organic functions. Drug discovery is a
time-consuming, costly, difficult, and inefficient process that yields very few medicinal
breakthroughs. Drug research and design involves the capturing of structural information
for biological targets and small molecules as well as various in silico methods, such
as molecular docking and molecular dynamic simulation. This article proposes the idea
of expediting computational drug development through a collaboration of scientists and
universities, similar to the Human Genome Project using machine learning (ML) strategies.
We envision an automated system where readily available or novel small
molecules (chemical or plant-derived), as well as their biological targets, are uploaded
to an online database, which is constantly updated. For this system to function, machine
learning strategies have to be implemented, and high-quality datasets and high quality assurance
of the ML models will be required. ML can be applied to all computational drug
discovery fields, including hit discovery, target validation, lead optimization, drug repurposing,
and data mining of small compounds and biomolecule structures. Researchers
from various disciplines, such as bioengineers, bioinformaticians, geneticists, chemists,
computer and software engineers, and pharmacists, are expected to collaborate to establish
a solid workflow and certain parameters as well as constraints for a successful outcome.
This automated system may help speed up the drug discovery process while also
lowering the number of unsuccessful drug candidates. Additionally, this system will decrease
the workload, especially in computational studies, and expedite the process of
drug design. As a result, a drug may be manufactured in a relatively short time.

Authors: Singh Sonia
Published: October 2024

Cardiovascular disorders develop the highest rates of mortality and morbidity worldwide,
emphasizing the need for novel pharmacotherapies. The Chinese medicinal plant S. baicalensis
has a number of major active components, one of which is called baicalin. According to emerging
research, baicalin reduces chronic inflammation, immunological imbalance, lipid metabolism,
apoptosis, and oxidative stress. Baicalin improves endothelial function and protects the cardiovascular
system from oxidative stress-induced cell injury by scavenging free radicals and inhibiting
xanthine oxidase. Therefore, it helps prevent CVD such as hypertension, atherosclerosis, and cardiac
arrest. In this review, the therapeutic effects of baicalein are discussed in relation to both the
prevention and management of cardiovascular diseases.

Authors: Bodiwala Kunjan B. , Dhameliya Tejas M. , Sureja Dipen K. , Patel Manish P.
Published: October 2024

Background:

Aqueous solubility is a key parameter in understanding drug transport
in the body and also in the development of analytical methods. Determination of a complete
pH-solubility profile is essential during the pre-formulation stage, and it is also required to define
the class of drug according to the biopharmaceutical classification system.

Objectives:

This study aimed to generate solubility data to obtain a complete pH-solubility
profile for Atorvastatin calcium using the spectrophotometric method and to develop models
for the prediction of aqueous solubility of Atorvastatin calcium at a given combination of the
pH and temperature.

Methods:

The developed pH independent spectrophotometric method was applied to determine
the pH solubility profile of the drug at three different temperatures. Models for the prediction
of solubility were generated by using a full factorial design and validated by determining
solubility experimentally at some combinations of pH and temperature within the design
spaces.

Results:

Solubility of Atorvastatin calcium was found to increase gradually with pH within a
range of pH 1.2-4.0 and pH 9.0-12.0 while increasing drastically with pH within a range of pH
4.0-9.0 at all three temperatures. Experimental values of solubility of Atorvastatin calcium
were found to be in good agreement with predicted values from models.

Conclusion:

Predictive models generated from the experimental values are good indicative of
the solubility of Atorvastatin calcium with respect to temperature and pH of the medium and
can be used for accurate prediction of aqueous solubility within the design space of the models.

dosage form using the RP-HPLC method.

Methods:

RP-HPLC analysis was performed using a C18 column of dimension 150×4.6mm, 5
μ. The chromatography system comprised an Agilent 1220 Infinity II LC equipped with a
VWD detector and a 1220 Infinity II LC binary pump, wherein the instrument operation was
managed through Control Panel software at a flow rate of 0.5 ml/min. Methanol: water in the
ratio of 55:45 was used as the mobile phase, and the effluents were analyzed at 275nm. The
proposed method was validated for various parameters like linearity, precision, accuracy, robustness,
ruggedness, selectivity, limit of detection, limit of quantification, and assay as per the
ICH Q2(R1) guidelines.

Results:

Linearity was noted over a concentration range of 50-250 μg/ml with a correlation coefficient
of 0.999. The limit of detection (LOD) and limit of quantification (LOQ) were determined
to be 16.02 and 48.56 μg/mL, respectively. The % RSD for interday and intraday precision
studies was less than 2%, which was within the official RSD limit. Recovery analysis performed
using marketed formulation was found to be in the range of 97-105%.

Conclusion:

The method developed was validated according to the ICH guidelines. Hence, it is
evident that the developed method is novel, sensitive, precise, and reliable, and it can be successfully
applied to estimate Calotropis gigantea in bulk material and its herbal dosage form.

Published: October 2024

The Stone Matrix Asphalt (SMA) concrete mixture generally consists of aggregates, fillers, and additives. Stone dust filler has become a scarce component in the composition of the mix. One alternative filler that can be used is geothermal waste, which contributes to environmental pollution reduction and enhances its utility. This research investigates the influence of geothermal waste content as a substitute filler on the characteristics of Stone Matrix Asphalt (SMA) mixtures. The laboratory research follows the SNI 8129:2015, examining aggregate, filler, and asphalt materials. Subsequently, test specimens are fabricated to determine the optimum asphalt content (OAC). The OAC produces test specimens for Marshall, VCA, IRS, ITS, TSR, CL, and AFD tests. These tests are conducted at each geothermal waste filler substitution level, ranging from 0%, 10%, 20%, 30%, to 40%. The analysis results indicate that using geothermal waste as a filler in SMA mixtures performs optimally at a 40% substitution level. Increasing the substitution level enhances VFWA and density while decreasing VITM and VMA, as well as flow values. The SMA mixture achieves good stone-on-stone contact, demonstrated by the VCA value. As IRS and TSR indicate, geothermal waste improves stability and indirect tensile strength, enhancing the mixture's durability. Geothermal waste enhances the overall integration and homogeneity of the mix, making it resistant to plastic deformation and high temperatures, as observed in CL results.
The Effect of Pilot Reaction Time and Line-Up Time on Runway Occupancy Time Take-Off about Runway Capacity (Case Study: Soekarno-Hatta International Airport)

Published: October 2024

One way to increase runway capacity is to set the Runway Occupancy Time Take-Off (ROTT) standard. Following the Aeronautical Information Publication of Soekarno-Hatta International Airport, the ROTT standard is set at 90 seconds. However, many aircraft have a ROTT of more than the standard. This can cause a decrease in the optimal level of runway capacity utilization. It is suspected that factors affect ROTT, namely Pilot Reaction Time and Line-Up Time. This study aims to analyze the effect of Pilot Reaction Time and Line-Up Time on ROTT at Soekarno-Hatta International Airport. The population used is aircraft taking off from Soekarno-Hatta International Airport, with the sample being aircraft taking off in peak seasons. The research method uses Quantitative Methods with observation data collection techniques using the Doratask Method. The data was processed using Non-Parametric Statistics using the Spearman Rank Correlation Method. The results of this study indicate that pilot reaction time has no significant effect on ROTT. However, pilot reaction time has a significant positive and strong relationship with ROTT. Line-up time significantly influences ROTT with a positive and very strong relationship. Pilot reaction time and line-up time simultaneously significantly influence ROTT with a positive and very strong relationship. Pilot reaction time and line-up time have a significant positive relationship.

As population growth continues, so does consumption and the need for basic human necessities, necessitating ongoing development. This development process often relies on non-renewable resources, generates waste, and emits harmful gases, usually neglecting sustainability. The Circular Economy (CE) concept can be applied to support sustainability in the construction industry. This regenerative system replaces the linear economy, focusing on optimizing material utilization and value throughout the product lifecycle and reducing waste generation. Through a Systematic Literature Review based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, this research provides an overview of CE practice trends that the construction industry in Indonesia can adopt based on lessons learned from other countries. The results indicate that CE implementation in Indonesia is highly relevant and important for supporting sustainability from economic, environmental, and social perspectives. To achieve these benefits, Indonesia must overcome various barriers, including less supportive policies, low consumer demand, limitations in the supply chain, and technological and infrastructure constraints. The CE principles commonly applied by the Indonesian construction industry in waste are reduction, reuse, and recovery. To ensure the successful implementation of CE in the construction sector, the Indonesian construction industry can learn from the best CE practices implemented in other countries and adopt effective and efficient strategies to achieve sustainability. However, successful implementation requires commitment and collaboration from various stakeholders, including the government, industry, and academia.

Published: October 2024

La tolerancia al frío tiene valor adaptativo en plantas perennes de clima templado-frío, por lo que es importante detectar variación genética en ella para árboles forestales. En dos ensayos de progenie de Pinus pseudostrobus establecidos en Pueblo Nuevo, Puebla (S1, 2853 m) y Teolocholco, Tlaxcala (S2, 2355 m), se determinó el índice de daño celular (ID) en plantas de cuatro años con una prueba de congelamiento, y se estimó su relación con el crecimiento en altura y variables bioclimáticas del sitio de origen de las familias en la región central de México. La tolerancia a frío se determinó con la pérdida de electrolitos (ID) a -15 °C durante 4 h. El análisis de varianza se realizó con Proc Mixed, usando un diseño de bloques completos al azar. El ID fue diferente (P<0.05) entre sitios y mayor en S1 (60.7%) que en S2 (50%); los parámetros genéticos indicaron que la tolerancia al frío está bajo control genético (h2f ≥0.50).  El crecimiento en altura de las plantas en S2 fue mayor que en S1. Las variables bioclimáticas de mayor correlación (r≥0.55) con ID y el crecimiento en altura están relacionadas con la humedad, temperatura y precipitación de otoño-invierno. El daño por heladas en las familias varió entre sitios, lo que demuestra que existe interacción genotipo-ambiente asociada con resistencia al frío para algunas progenies; además de que los factores climáticos asociados con la humedad, la temperatura y precipitación también son importantes en la adaptación y crecimiento de las progenies de P. pseudostrobus

Assessing Visitor Expectations of AI Nursing Robots in Hospital Settings: Cross-Sectional Study Using the Kano Model
Authors: Kang Aimei , Wu XiuLi
Published: October 2024

Background

Globally, the rates at which the aging population and the prevalence of chronic diseases are increasing are substantial. With declining birth rates and a growing percentage of older individuals, the demand for nursing staff is steadily rising. However, the shortage of nursing personnel has been a long-standing issue. In recent years, numerous researchers have advocated for the implementation of nursing robots as a substitute for traditional human labor.

Objective

This study analyzes hospital visitors’ attitudes and priorities regarding the functional areas of artificial intelligence (AI) nursing robots based on the Kano model. Building on this analysis, recommendations are provided for the functional optimization of AI nursing robots, aiming to facilitate their adoption in the nursing field.

Methods

Using a random sampling method, 457 hospital visitors were surveyed between December 2023 and March 2024 to compare the differences in demand for AI nursing robot functionalities among the visitors.

Results

A comparative analysis of the Kano attribute quadrant diagrams showed that visitors seeking hospitalization prioritized functional aspects that enhance medical activities. In contrast, visitors attending outpatient examinations focused more on functional points that assist in medical treatment. Additionally, visitors whose purpose was companionship and care emphasized functional aspects that offer psychological and life support to patients.

Conclusions

AI nursing robots serve various functional areas and cater to diverse audience groups. In the future, it is essential to thoroughly consider users’ functional needs and implement targeted functional developments to maximize the effectiveness of AI nursing robots.

Published: October 2024

Background

Artificial intelligence (AI) has been increasingly recognized as a potential solution to address mental health service challenges by automating tasks and providing new forms of support.

Objective

This study is the first in a series which aims to estimate the current rates of AI technology use as well as perceived benefits, harms, and risks experienced by community members (CMs) and mental health professionals (MHPs).

Methods

This study involved 2 web-based surveys conducted in Australia. The surveys collected data on demographics, technology comfort, attitudes toward AI, specific AI use cases, and experiences of benefits and harms from AI use. Descriptive statistics were calculated, and thematic analysis of open-ended responses were conducted.

Results

The final sample consisted of 107 CMs and 86 MHPs. General attitudes toward AI varied, with CMs reporting neutral and MHPs reporting more positive attitudes. Regarding AI usage, 28% (30/108) of CMs used AI, primarily for quick support (18/30, 60%) and as a personal therapist (14/30, 47%). Among MHPs, 43% (37/86) used AI; mostly for research (24/37, 65%) and report writing (20/37, 54%). While the majority found AI to be generally beneficial (23/30, 77% of CMs and 34/37, 92% of MHPs), specific harms and concerns were experienced by 47% (14/30) of CMs and 51% (19/37) of MHPs. There was an equal mix of positive and negative sentiment toward the future of AI in mental health care in open feedback.

Conclusions

Commercial AI tools are increasingly being used by CMs and MHPs. Respondents believe AI will offer future advantages for mental health care in terms of accessibility, cost reduction, personalization, and work efficiency. However, they were equally concerned about reducing human connection, ethics, privacy and regulation, medical errors, potential for misuse, and data security. Despite the immense potential, integration into mental health systems must be approached with caution, addressing legal and ethical concerns while developing safeguards to mitigate potential harms. Future surveys are planned to track use and acceptability of AI and associated issues over time.
Supervised and Unsupervised Screen Time and Its Association With Physical, Mental, and Social Health of School-Going Children in Dhaka, Bangladesh: Cross-Sectional Study

Published: October 2024

Background

Children’s screen time has substantially increased worldwide, including in Bangladesh, especially since the pandemic, which is raising concern about its potential adverse effects on their physical, mental, and social health. Parental supervision may play a crucial role in mitigating these negative impacts. However, there is a lack of empirical evidence assessing the relationship between parental screen time supervision and health outcomes among school children in Dhaka, Bangladesh.

Objective

We aimed to explore the association between supervised and unsupervised screen time on the physical, mental, and social health of school-going children in Dhaka, Bangladesh.

Methods

We conducted a cross-sectional descriptive study between July 2022 and June 2024. A total of 420 children, aged 6‐14 years, were enrolled via the stratified random sampling method across three English medium and three Bangla medium schools in Dhaka. Data were collected through a semistructured questionnaire; anthropometry measurements; and the Bangla-validated Strength and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI) Scale, and Spencer Children Anxiety Scale (SCAS).

Results

A total of 234 out of 420 students (56%) used digital screen devices without parental supervision. We did not find a substantial difference in the duration of the daily mean use of digital devices among the supervised students (4.5 hours, SD 2.2 hours) and the unsupervised students (4.6 hours, SD 2.4 hours). According to the type of school, English medium school children had a mean higher screen time (5.46 hours, SD 2.32 hours) compared to Bangla medium school children (3.67 hours, SD 2.00 hours). Headache was significantly higher among the unsupervised digital screen users compared to those who used digital screens with parental supervision (175/336 students, 52.1% versus 161/336 students, 47.9%; P<.003). Moreover, students who used digital screens without parental supervision had poor quality of sleep. Behavioral problems such as conduct issues (119/420 students, 28.3%) and peer difficulties (121/420 students, 28.8%) were observed among the participants. However, when comparing supervised and unsupervised students, we found no statistically significant differences in the prevalence of these issues.

Conclusions

The findings of the study showed that the lack of screen time supervision is associated with negative health effects in children. The roles of various stakeholders, including schools, parents, policy makers, and students themselves, are crucial in developing effective guidelines for managing screen use among students. Further research is needed to demonstrate causal mechanisms; identify the best interventions; and determine the role of mediators and moderators in households, surroundings, and schools.
