Authors: Jamil Alvian Nur , Thohir Muhammad
Published: November 2023

The role of technology in the education sector is increasing and has impacted the realm of learning activities. Technology-integrated learning is highly needed to facilitate both teachers and students in their activities. Using asynchronous learning models provides flexibility with easy and efficient access in terms of time. The research aims to describe the implementation of the asynchronous learning model assisted by videos in the subject of akidah akhlak, as well as the learning outcomes of the experimental and control groups, and the effectiveness of the asynchronous learning model assisted by videos in improving student learning outcomes. The research method used is quantitative with a proper experimental design. The experiment takes the form of a pretest-posttest control group design, with an experimental class receiving treatment in the form of asynchronous learning assisted by videos, and a control class implementing conventional methods. The research results show that the questionnaire on video implementation obtained a TCR score of 82.95% for variable X and 81.79% for variable Y, both falling within the 81-100% interval scale, indicating a "Very Good" category. The post-test results of the experimental class yielded a score of 86.43, while the control class scored 76.57. The paired sample t-test showed an average difference of 15.29 for the experimental class, while the control class had an average difference of 8.71, with a n-gain value of 0.27 for the control class, indicating a "low" category, whereas the experimental class had a n-gain value of 0.53, falling within the "middle" category. The implementation of engaging video learning media creates a non-monotonous learning atmosphere, and the questionnaire on video implementation received a "Very Good" rating. The use of the asynchronous learning model assisted by videos effectively improves student learning outcomes in Islamic creed and ethics, as evidenced by a larger difference in the experimental class compared to the control class.
Experience ecosystems and healthcare design
Authors: David Gary C
Published: November 2023

When thinking about experience design, our attention often goes to individual categories of people, such as customers, patients, users, employees, and the like. However, people do not exist outside of systems. Therefore, when considering designs, we need to consider the entire experience ecosystem and how elements of those system intersect and align. We examine this principle through the lens of medical records and EHR systems. By approaching design through a systems perspective, we can create better solutions that fit the broader needs of system stakeholders. We conclude with recommendations for how to better execute a systems design approach to foster better integrative experiences.
Study of the Effect of Diabetes Mellitus I on Bone Mineral Density of
Upper and Lower Limbs by Dual-Energy X-Ray Absorptiometry
Authors: Sami Abdel Aziz1 Zainab , Dawood Numan S. , Al-khalisy Maan H.
Published: November 2023

Background: Bone mineral density (BMD) has been assessed using Dual-Energy
X-ray absorptiometry (DEXA). This procedure is considered to be of vital importance in assessing the general condition of individuals concerning their skeletal
mineralization. BMD is measured according to the results of the DEXA examination of the vertebral column and pelvis. Although diabetes mellitus (D.M.)is
known to affect BMD, the information regarding this relationship is not currently
particularly clear. Objective: This study concentrates on the point that the assessment of BMD for the vertebral column is insuffi-cient to give a realistic and
correct picture of the mineralization of the remaining part of the skeleton. Besides,
this study elicited a generalized view of the mineralization of the different body
parts between genders and between the left and right sides of the body. The effect
of DM I on BMD was evaluated well in this research. Method: This study involved
165 patients complaining of bone pain (85 male and 80 female), about half of
whom suffered from diabetes, involving both genders.
Further, 90 healthy volunteers had been studied and were considered to constitute
the control group. All individuals (255) in this study were exposed to the study of
their BMD via DEXA for all parts of the body. Results: The DEXA exam revealed
highly statistically significant differences between the sides of the body in the
same subject. In addition, there were significant differences in BMD between
females and males and highly statistically significant differences between the
control and patient groups with DM I. Finally, this study offered strong evidence
that the BMD of the vertebral column and pelvis did not give an accurate picture of
mineralization in the different parts of the body for a given subject.
In conclusion, the DEXA scan for the whole body and each part separately shows
promising results as alternative parameters of the DEXA scan for the spine or hip
only for accurate diagnosis. Our results indicate that the BMD of the left and right
sides for women was less than for men in all cases (average, osteoporosis, and
DMI with osteoporosis) for the same sides and between their upper and lower
limbs. Patients with DMI revealed significant reductions in BMD in comparison
with other subjects who were not diabetic, even if they had osteoporosis.

The effect of different enamel surface preparations on microleakage
under orthodontic brackets
Authors: Asaad Ali Ayat , Issa Saleem Alan
Published: November 2023

Microleakage is caused by many factors, including polymerization shrinkage of
the resin, thermal expansion differences between the enamel and the adhesive,
and inadequate adherence. This study aims to assess the microleakage value under orthodontic brackets after three distinct enamel surface preparations and
compare the results to the traditional procedure. Fifty-four intact upper premolars
were randomly distributed into three groups. First group 18 teeth etched with
36% phosphoric acid Dentsply. Second group 18 teeth etched with %1.23 acidulated phosphate fluoride (APF) incorporated phosphoric acid 25%APF
75%phosphoric acid Dentsply. Third group 18 teeth etched with Trans
Bond TM Plus Self-Etching prime 3M Unitek, Monrovia, USA. Then, according to
the manufacturer's instructions, all groups bonded to stainless steel brackets RAZOR, IOS, USA, using light-cured composite 3M Unitek/ Monrovia, USA. Then,
each subgroup was divided into 3 subgroups, 6 teeth each. The first subgroup
thermocycled 500 cycles between 5 C and 55 UC in deionized water and tested
after 24 hours of water storage. The second subgroup was also thermocycled and
tested after 2 months of water storage. The third subgroup was subjected to cyclic
acid attack for 2 months by an acidic solution pH=2.5. Microleakage was evaluated using a dye penetration technique. All samples are sectioned and evaluated
under a stereomicroscope. For statistical analysis, the Kruskal-Wallis test was
employed. P=0.05 was the level of significance. A significant difference was between etching groups following a thermocycler and a twenty-four-hour water
storage, no significant difference after thermocycling and two months of water
storage, and significant difference at the occlusal side and between overall means
of compared etching groups. This study revealed that the highest microleakage
values were in the SEP self-etch prime group, then EF 1.23% APF incorporated
phosphoric acid group and the ER 36% phosphoric acid group. The gingival side
had more microleakage than the occlusal side. Adding around 20-25 percent of
1.23 percent of phosphoric acid for enamel preparation before orthodontic bonding increases microleakage values, but SEP remains the highest.

Published: November 2023

Background: Chitosan is a promising polymeric that has received much attention
recently. Chitosan nanoparticles have wide applications as a nanocarrier for
different organic and inorganic substances. Materials and Methods: In the present
study, copper (CuNPs), chitosan nanoparticles (CNPs) and Cu/CS nanocomposite
(Cu/CNC) were prepared and characterized. All prepared nanoparticles were
inspected by X-ray diffraction (XRD), Fourier transform infrared spectroscopy
(FTIR), Field emission scanning electron microscope (FE-SEM ), Energy
Dispersive Spectroscopy (EDS), UV/VIS spectroscopy, and zeta potential. Finally,
the antimicrobial activity of CuNPs, CNPs and Cu/CNC was tested by disc
diffusion assay at different concentrations (0.5-2 mg/ml) against Candida albicans,
Klebsiella. pneumoniae , Pseudomonas aeruginosa , Proteus mirabilis ,
Cryptococcus sp. , Staphylococcus aureus, Escherichia coli, and Acinetobacter sp.
Results: The results showed an absorbance peak at 550 nm due to the presence of
Cu/CNC. From the FTIR spectrum, a peak at 686.66 cm-1 refers to the copper
successfully binding with chitosan. Furthermore, the particle size average of
Cu/CNC was 36.34 - 48.27
Cu/CNC has the highest growth inhibition zone at a concentration of 2 mg/ml
against C.albicans, P.aeruginosa and S.aureus with the diameters (9.75±0.35,
15±1.41, 15.5±0.70) mm, respectively. Conclusion: This study showed that
Cu/CNC has higher antimicrobial activity than CNPs and CuNPs. It presented
higher antibacterial activity against gram-negative bacteria than gram-positive
bacteria.

Nonface-to-Face Visitation to Restrict Patient Visits for Infection Control: Integrative Review
Authors: Jeong Hyunwoo , Choi Yonsu , Kim Heejung
Published: November 2023

Background

In the COVID-19 pandemic, a visit restriction policy for patients has been implemented in medical institutions worldwide and visits are being made using alternative communication technologies. This shift has also required the use of platforms to prevent negative consequences of these restrictions.

Objective

The purpose of this review was to comprehensively explore nonface-to-face visits as an alternative during infection prevention and to synthesize the scientific evidence of their benefits and disadvantages.

Methods

A comprehensive search was conducted via the PubMed, Embase, CINAHL, Cochrane, and Web of Science electronic databases; unpublished trials in the clinical trials register ClinicalTrials.gov; and Virginia Henderson International Nursing Library up to September 10, 2021. The search query was developed according to the guidelines of the Peer Review of Electronic Search Strategies and included keywords on the topics of telemedicine and visitation restrictions. The inclusion criteria were a nonface-to-face modality using telemedicine with family in a hospital setting, experimental and observational studies, and articles written in English. The exclusion criteria were inaccessible in full text, not related to patient or family involvement, mainly focused on the study protocol, or only discussing the pros and cons of telemedicine.

Results

Overall, patients’ families experienced emotional distress due to restrictions on face-to-face visits. Nonface-to-face virtual visits compensating for these restrictions had a positive effect on reducing the risk of infection to the patient and the family. This further encouraged psychological and physical recovery and decreased psychological distress. However, nonface-to-face virtual technology could not replace the existence of actual families, and technical problems with networks and devices are reported as limitations.

Conclusions

Ensuring the availability of technology and educating on the same in alignment with the characteristics of patients and their families, nonface-to-face virtual visits need to show more potential as an effective patient-centered treatment strategy based on more research and advanced practice.
The Effects of Antenatal Interventions on Gestational Weight Gain in Low- and Middle-Income Countries: Protocol for a Systematic Review
Authors: Wang Dongqing , Nguyen Christine H , Fawzi Wafaie W
Published: November 2023

Background

Gestational weight gain (GWG) is a crucial determinant of maternal and child outcomes yet remains an underused target for antenatal interventions in low- and middle-income countries (LMICs).

Objective

This systematic review aims to identify and summarize educational, behavioral, nutritional, and medical interventions on GWG from randomized controlled trials conducted in LMICs.

Methods

Randomized controlled trials that documented the effects of antenatal interventions on GWG in LMICs will be included. The interventions of interest will be educational, behavioral, nutritional, or medical. A systematic literature search will be conducted using PubMed, Embase, Web of Science, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Library from the inception of each database through October 2022 (with an updated search in January 2024). A total of 2 team members will independently perform the screening of studies and data extraction. A narrative synthesis of all the included studies will be provided. The risk of bias will be assessed using the Cochrane Risk of Bias tool. The certainty of the evidence for each homogeneous group of interventions will be assessed using the GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach. A narrative synthesis of the included studies will be conducted to summarize mean differences (with 95% CIs) for continuous outcomes and risk ratios, rate ratios, hazard ratios, or odds ratios (with 95% CIs) for dichotomous or categorical outcomes. Available information on the costs of interventions will also be summarized to facilitate the adoption and scale-up of effective GWG interventions.

Results

The development of the research questions, search strategy, and search protocol was started on September 20, 2022. The database searches and the importation of the identified records into Covidence were performed on October 7, 2022. As of September 2023, the title and abstract screening was ongoing. The target completion time of this systematic review is April 2024.

Conclusions

Without effective interventions to manage GWG, the potential to improve maternal and child health through optimal GWG remains unrealized in LMICs. This systematic review will inform the design and implementation of antenatal interventions to prevent inadequate and excessive GWG in resource-limited settings.

Predicting Early Dropout in a Digital Tobacco Cessation Intervention: Replication and Extension Study (Preprint)
Authors: Yu Linda Q , Amato Michael S , Papandonatos George D , Cha Sarah , Graham Amanda L
Published: November 2023

BACKGROUND

Detecting early dropout from digital interventions is crucial for developing strategies to enhance user retention and improve health-related behavioral outcomes. Bricker and colleagues proposed a single metric that accurately predicted early dropout from 4 digital tobacco cessation interventions based on log-in data in the initial week after registration. Generalization of this method to additional interventions and modalities would strengthen confidence in the approach and facilitate additional research drawing on it to increase user retention.

OBJECTIVE

This study had two research questions (RQ): RQ1—can the study by Bricker and colleagues be replicated using data from a large-scale observational, multimodal intervention to predict early dropout? and RQ2—can first-week engagement patterns identify users at the greatest risk for early dropout, to inform development of potential “rescue” interventions?

METHODS

Data from web users were drawn from EX, a freely available, multimodal digital intervention for tobacco cessation (N=70,265). First-week engagement was operationalized as any website page views or SMS text message responses within 1 week after registration. Early dropout was defined as having no subsequent engagement after that initial week through 1 year. First, a multivariate regression model was used to predict early dropout. Model predictors were dichotomous measures of engagement in each of the initial 6 days (days 2-7) following registration (day 1). Next, 6 univariate regression models were compared in terms of their discrimination ability to predict early dropout. The sole predictor of each model was a dichotomous measure of whether users had reengaged with the intervention by a particular day of the first week (calculated separately for each of 2-7 days).

RESULTS

For RQ1, the area under the receiver operating characteristic curve (AUC) of the multivariate model in predicting dropout after 1 week was 0.72 (95% CI 0.71-0.73), which was within the range of AUC metrics found in the study by Bricker and colleagues. For RQ2, the AUCs of the univariate models increased with each successive day until day 4 (0.66, 95% CI 0.65-0.67). The sensitivity of the models decreased (range 0.79-0.59) and the specificity increased (range 0.48-0.73) with each successive day.

CONCLUSIONS

This study provides independent validation of the use of first-week engagement to predict early dropout, demonstrating that the method generalizes across intervention modalities and engagement metrics. As digital intervention researchers continue to address the challenges of low engagement and early dropout, these results suggest that first-week engagement is a useful construct with predictive validity that is robust across interventions and definitions. Future research should explore the applicability and efficiency of this model to develop interventions to increase retention and improve health behavioral outcomes.

La Reserva Jaguar del Norte es una propiedad privada ubicada en la sierra sonorense, dentro de una compleja matriz paisajística, con un amplio legado de uso ganadero. Esta región, identificada como prioritaria para la conservación, dispone de pocos datos sobre las trayectorias de cambio en la vegetación, un elemento clave para evaluar el impacto de las áreas naturales protegidas. Este trabajo presenta información acerca del efecto de las acciones con fines de conservación, sobre la composición de la vegetación tras el establecimiento de la reserva en el año 2003. Para ésto, se caracterizaron las comunidades vegetales presentes y se generaron clasificaciones supervisadas de cobertura con imágenes satelitales de mediana y alta resolución para realizar un análisis cambio de la cobertura vegetal (2003-2018). Las precisiones generales de las clasificaciones fueron iguales o superiores a 0.75, valor que aumentó al utilizar imágenes de mayor resolución espacial. El uso combinado de diferentes resoluciones espaciales presentó ventajas para entender las transiciones de composición entre diferentes comunidades vegetales. Las tendencias encontradas indicaron un aumento del matorral subtropical y una disminución del pastizal inducido, lo que refleja transformaciones hacia una mayor diversidad de especies y una reducción de posibles amenazas para la biodiversidad a nivel paisaje.

The article examines the role and place, the peculiarities of functioning of one of the most specifi c groups of the Soviet society of the clergy. A brief digression is given concerning the policy of the Soviet government in relation to the Muslim clergy of the subregion. It is emphasized that this group in the fi rst Soviet decades went through a diffi cult path from a strategic partner of the young Soviet government, which made a signifi cant contribution to its victory in the subregion under consideration, to a principled opponent subjected to repression. It is noted that during the Great Patriotic War, despite the fundamental changes in the sphere of state- confessional relations, there was a break in the continuity of generations of ministers of worship in the republic, as a result of which a personnel vacuum was formed. It is associated with the specifi cs of the religious policy of the occupation authorities. The sources of recruitment of the Muslim clergy of the period of the 40–80s of the 20th century, their origin, educational level, role and place in the society of the subregion are analyzed. The statements and conclusions put forward are supported by archival documents. In conclusion, it is concluded that, despite the low level of preparedness and narrowed functionality, the Muslim clergy of Kabardino- Balkaria of the historical period under consideration fulfi lled the role of the guardian of religious knowledge and traditions. Thus, it played an important role in maintaining household religiosity, the level of which in these years continued to remain quite high.
Tamper Detection against Unitary Operators

Security of a storage device against a tampering adversary has been a well-studied topic in classical cryptography. Such models give black-box access to an adversary, and the aim is to protect the stored message or abort the protocol if there is any tampering.In this work, we extend the scope of the theory of tamper detection codes against an adversary with quantum capabilities. We consider encoding and decoding schemes that are used to encode a k-qubit quantum message |m⟩ to obtain an n-qubit quantum codeword |ψm⟩. A quantum codeword |ψm⟩ can be adversarially tampered via a unitary U from some known tampering unitary family UAdv (acting on C2n).Firstly, we initiate the general study of quantum tamper detection codes, which detect if there is any tampering caused by the action of a unitary operator. In case there was no tampering, we would like to output the original message. We show that quantum tamper detection codes exist for any family of unitary operators UAdv, such that |UAdv|<22αn for some constant α∈(0,1/6); provided that unitary operators are not too close to the identity operator. Quantum tamper detection codes that we construct can be considered to be quantum variants of classical tamper detection codes studied by Jafargholi and Wichs ['15], which are also known to exist under similar restrictions.Additionally, we show that when the message set M is classical, such a construction can be realized as a non-malleable code against any UAdv of size up to 22αn.
The promise of N-Acetylcysteine in the Treatment of Obsessive-Compulsive Disorder
Authors: Carollo Massimo , Carollo Nicola , Montan Giulia
Published: November 2023

Obsessive-compulsive disorder (OCD) is a challenging psychiatric
condition with limited treatment responses to standard therapies like
selective serotonin reuptake inhibitors and cognitive-behavioral
therapy. This letter to the Editor is intended to raise awareness within
the scientific community about the potential use of N-acetylcysteine
(NAC) as an alternative treatment, targeting the glutamatergic system
dysfunctions and the inflammatory cytokines implicated in OCD.
Preliminary studies suggest that NAC, at doses of 2,000-3,000 mg daily,
can significantly alleviate OCD symptoms. Despite its promise and
favourable safety profile, further research is imperative to establish
optimal dosages and long-term efficacy. To date, the lack of suitable
pharmaceutical forms with appropriate dosages hinders its empirical
clinical application. In conclusion, NAC offers a potential adjunctive
treatment for OCD, meriting more rigorous investigation.
A Backup Protection Scheme for Hybrid HVDC Transmission System Combining Energy Function and Directional Criterion

Published: November 2023

By combining the LCC rectifier and MMC converter, the hybrid HVDC
transmission system reduces the construction cost while avoiding the
commutation failure problem. However, traditional protection schemes for
HVDC transmission systems are not fully suitable for the hybrid HVDC
transmission system with two types of converters. A new backup
protection scheme is proposed in this paper to improve the reliability
of the hybrid HVDC transmission system. The energy functions for two
types of converters are first constructed using data at the AC side to
obtain the energy level of each converter. The backup protection scheme
is then designed by calculating the improved Hausdorff distance change
rates of energy levels, which is a supplement to the traditional
protection scheme using DC voltage/current. Furthermore, a directional
protection scheme is introduced to identify the fault near the T area.
The proposed protection scheme is verified by the Wudongde ±800kV
three-terminal hybrid HVDC transmission model built on PSCAD. The
results show that the proposed protection scheme can identify the fault
pole and the fault line even in the case of up to 800Ω fault resistance.
Sliding indents of hard coatings: analysis of failure morphologies and intermediate fracture energies
Authors: Bhattacharyya A S
Published: November 2023

Sliding tests both in micro and nano level were done on hard coatings developed on silicon substrates and 304SS substrates using magnetron sputtering. Different types of failure morphologies manifested themselves and were found to be a function of substrate, indenter, loading nature apert from the coating. Linear profiles of the failed segments along with analysis of the scratch track were done which provided a qualitative depiction of adhesive, wear and abrasive properties of the coatings useful for their heavy duty and microelectronic applications
Far-field effects of the Nile damming on the silica cycle in the Southeastern Mediterranean Sea

Published: November 2023

Silica plays a key role in the growth of silicifying primary producers
(e.g., diatoms) and hence the ocean carbon pump. The Mediterranean Sea’s
eastern Levantine Basin (ELB) is a low silica (and low N and P)
ultra-oligotrophic basin. Before 1965, Nile autumn floods were a major
source of dissolved silica (DSi) and other nutrients to primary
producers of the ELB continental shelf, also known as the Nilotic cell.
The construction of the Aswan High Dam (AHD) in the mid-1960s, blocked
these floods, drastically diminishing the autumn-diatom blooms offshore
the Nile delta. However, the far-reaching and long-lasting effects of
the Nile damming on the Si cycle in the ELB remain unclear. Here, we
studied the distribution of biogenic silica in deep-sea short sediment
cores, collected hundreds of kilometers from the Nile outlet, at depths
range of 1100 – 1900 m, offshore the ELB Israeli coast. We show a
concurrent decrease (of up to 79%) in biogenic silica accumulation
rates in surficial sediments relative to underlying sediments, mostly
reflecting the effects of Si (dissolved and particulate) retention by
the AHD on diatoms production, export and burial in the ELB. This
far-field effect was most pronounced in deep-sea areas subjected to
intense lateral transport of resuspended sediments from the shelf via
intermediate nepheloid layers and to coastal water intrusions, along the
path of the pre-dam, flood plumes. Our core records show that the AHD
worsened nutrient-diminished, unfavorable conditions for diatoms that
persisted in the deep ELB at least during the last four millennia.
Long-term Response of Peatland Carbon Exchange to Climatic Changes in the Hudson Bay Lowlands

Published: November 2023

Northern peatlands have been a persistent net sink of atmospheric carbon
(C) due to the greater rates of gross primary production (GPP) compared
to ecosystem respiration (ER). Global warming has raised concerns about
the C sink strength of northern environments. In the vast peatlands of
the Hudson Bay Lowlands (HBL) region of Canada, warming-induced changes
in sea ice dynamics over the Bay have altered its advective influence on
the adjacent lowlands. Despite our knowledge of the short-term C
exchange in these peatlands, there remain uncertainties in the long-term
combined response of GPP and ER to climate change. In this study, the
satellite data-driven Vegetation Photosynthesis and Respiration Model
(VPRM) was employed to investigate the response of peatland GPP, ER, and
net ecosystem exchange (NEE) to temperature and moisture changes. The
results show contrasting net CO2 exchange at the two peatland sites over
the last 20 years, with the fen acting as a net C source (+24 g C m-2)
to the atmosphere and the bog serving as a net C sink (-130 g C m-2).
There is ample evidence that a warmer and wetter climate enhanced GPP
more than ER, while cooler temperatures weakened the peatland net C
sink, regardless of the moisture conditions. Additionally, the advective
influence of Hudson Bay on the lowlands produced markedly different C
dynamics between offshore and onshore winds, with higher respiration
rates (12%–26%) during offshore winds. We discuss the implications
for peatland C balance under more frequent onshore winds in the region.

Stratospheric sulfate aerosols play a key role on atmospheric chemistry
and Earth’s radiation budget, but their size distribution, a critical
parameter in climate models, is generally poorly-known. We address such
gap for the 2022 Hunga Tonga-Hunga Ha’apai (HT-HH) volcanic eruption by
exhaustively analyzing a set of satellite observations (TROPOMI, IASI,
AHI, CALIOP) together with photometric ground observations from the
worldwide open-access AERONET network. We document a rapid growth of
HT-HH sulfate aerosols in the days following eruption, faster than
observed for 1991 Pinatubo eruption, likely due to the exceptional
hydration of the stratosphere by this phreatomagmatic eruption. An
unusual aerosol fine mode (peak radius in 0.3-0.5 µm) is identified at
20 stations of the southern hemisphere until May 2023 (time of writing).
Nevertheless, 1.4 years after eruption, HT-HH sulfate aerosols remain
smaller than Pinatubo particles. Smaller aerosols backscatter more
efficiently visible light and sediment more slowly than larger
particles, implying stronger and longer-lasting negative radiative
forcing.
