Published: July 2020

Background

Atrial fibrillation (AF) is a common arrhythmia that adversely affects health-related quality of life (HRQoL). We conducted a pilot trial of individuals with AF using a smartphone to provide a relational agent as well as rhythm monitoring. We employed our pilot to measure acceptability and adherence and to assess its effectiveness in improving HRQoL and adherence.

Objective

This study aims to measure acceptability and adherence and to assess its effectiveness to improve HRQoL and adherence.

Methods

Participants were recruited from ambulatory clinics and randomized to a 30-day intervention or usual care. We collected baseline characteristics and conducted baseline and 30-day assessments of HRQoL using the Atrial Fibrillation Effect on Quality of Life (AFEQT) measure and self-reported adherence to anticoagulation. The intervention consisted of a smartphone-based relational agent, which simulates face-to-face counseling and delivered content on AF education, adherence, and symptom monitoring with prompted rhythm monitoring. We compared differences in AFEQT and adherence at 30 days, adjusted for baseline values. We quantified participants’ use and acceptability of the intervention.

Results

A total of 120 participants were recruited and randomized (59 to control and 61 to intervention) to the pilot trial (mean age 72.1 years, SD 9.10; 62/120, 51.7% women). The control group had a 95% follow-up, and the intervention group had a 93% follow-up. The intervention group demonstrated significantly higher improvement in total AFEQT scores (adjusted mean difference 4.5; 95% CI 0.6-8.3; P=.03) and in daily activity (adjusted mean difference 7.1; 95% CI 1.8-12.4; P=.009) compared with the control between baseline and 30 days. The intervention group showed significantly improved self-reported adherence to anticoagulation therapy at 30 days (intervention 3.5%; control 23.2%; adjusted difference 16.6%; 95% CI 2.8%-30.4%; P<.001). Qualitative assessments of acceptability identified that participants found the relational agent useful, informative, and trustworthy.

Conclusions

Individuals randomized to a 30-day smartphone intervention with a relational agent and rhythm monitoring showed significant improvement in HRQoL and adherence. Participants had favorable acceptability of the intervention with both objective use and qualitative assessments of acceptability.

Authors: Wu Huailiang , Sun Weiwei , Huang Xinyu , Yu Shinning , Wang Hao , Bi Xiaoyu , Sheng Jie , Chen Sihan , Akinwunmi Babatunde , Zhang Casper J P , Ming Wai-Kit
Published: July 2020

People across the world have been greatly affected by the ongoing coronavirus disease (COVID-19) pandemic. The high infection risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in hospitals is particularly problematic for recently delivered mothers and currently pregnant women who require professional antenatal care. Online antenatal care would be a preferable alternative for these women since it can provide pregnancy-related information and remote clinic consultations. In addition, online antenatal care may help to provide relatively economical medical services and diminish health care inequality due to its convenience and cost-effectiveness, especially in developing countries or regions. However, some pregnant women will doubt the reliability of such online information. Therefore, it is important to ensure the quality and safety of online services and establish a stable, mutual trust between the pregnant women, the obstetric care providers and the technology vis-a-vis the online programs. Here, we report how the COVID-19 pandemic brings not only opportunities for the development and popularization of online antenatal care programs but also challenges.
Public Perception of Artificial Intelligence in Medical Care: Content Analysis of Social Media (Preprint)
Authors: Gao Shuqing , He Lingnan , Chen Yue , Li Dan , Lai Kaisheng
Published: July 2020

BACKGROUND

High-quality medical resources are in high demand worldwide, and the application of artificial intelligence (AI) in medical care may help alleviate the crisis related to this shortage. The development of the medical AI industry depends to a certain extent on whether industry experts have a comprehensive understanding of the public’s views on medical AI. Currently, the opinions of the general public on this matter remain unclear.

OBJECTIVE

The purpose of this study is to explore the public perception of AI in medical care through a content analysis of social media data, including specific topics that the public is concerned about; public attitudes toward AI in medical care and the reasons for them; and public opinion on whether AI can replace human doctors.

METHODS

Through an application programming interface, we collected a data set from the Sina Weibo platform comprising more than 16 million users throughout China by crawling all public posts from January to December 2017. Based on this data set, we identified 2315 posts related to AI in medical care and classified them through content analysis.

RESULTS

Among the 2315 identified posts, we found three types of AI topics discussed on the platform: (1) technology and application (n=987, 42.63%), (2) industry development (n=706, 30.50%), and (3) impact on society (n=622, 26.87%). Out of 956 posts where public attitudes were expressed, 59.4% (n=568), 34.4% (n=329), and 6.2% (n=59) of the posts expressed positive, neutral, and negative attitudes, respectively. The immaturity of AI technology (27/59, 46%) and a distrust of related companies (n=15, 25%) were the two main reasons for the negative attitudes. Across 200 posts that mentioned public attitudes toward replacing human doctors with AI, 47.5% (n=95) and 32.5% (n=65) of the posts expressed that AI would completely or partially replace human doctors, respectively. In comparison, 20.0% (n=40) of the posts expressed that AI would not replace human doctors.

CONCLUSIONS

Our findings indicate that people are most concerned about AI technology and applications. Generally, the majority of people held positive attitudes and believed that AI doctors would completely or partially replace human ones. Compared with previous studies on medical doctors, the general public has a more positive attitude toward medical AI. Lack of trust in AI and the absence of the humanistic care factor are essential reasons why some people still have a negative attitude toward medical AI. We suggest that practitioners may need to pay more attention to promoting the credibility of technology companies and meeting patients’ emotional needs instead of focusing merely on technical issues.
ВЛИЯНИЕ ТВЕРДОФАЗНОЙ РЕКРИСТАЛЛИЗАЦИИ С ДВОЙНОЙ ИМПЛАНТАЦИЕЙ НА ПЛОТНОСТЬ СТРУКТУРНЫХ ДЕФЕКТОВ В УЛЬТРАТОНКИХ СЛОЯХ КРЕМНИЯ НА САПФИРЕ

Высокая плотность структурных дефектов является основной проблемой при изготовлении электроники на гетероструктурах «кремний на сапфире» (КНС). Современный метод получения ультратонких структур КНС с помощью твердофазной эпитаксиальной рекристаллизации позволяет значительно снизить дефектность в гетероэпитаксиальном слое КНС. В данной работе ультратонкие (100 нм) слои КНС были получены путем рекристаллизации и утонения субмикронных (300 нм) слоев кремния на сапфире, обладающих различным структурным качеством. Плотность структурных дефектов в слоях КНС оценивалась с помощью рентгеноструктурного анализа и просвечивающей электронной микроскопии. Кривые качания от дифракционного отражения Si(400), полученные в ω-геометрии, продемонстрировали максимальную ширину на полувысоте пика не более 0,19-0,20° для ультратонких слоев КНС толщиной 100 нм. Формирование структурно совершенного субмикронного слоя КНС 300 нм на этапе газофазной эпитаксии обеспечивает существенное уменьшение плотности дислокаций в ультратонком кремнии на сапфире до значений ~1 • 104 см-1. Тестовые n-канальные МОП-транзисторы на ультратонких структурах КНС характеризовались подвижностью носителей в канале 725 см2 Вс-1.

The high density of structural defects is the main problem on the way to the production of electronics on silicon-on-sapphire (SOS) heteroepitaxial wafers. The modern method of obtaining ultrathin SOS wafers is solid-phase epitaxial recrystallization which can significantly reduce the density of defects in the SOS heteroepitaxial layers. In the current work, ultrathin (100 nm) SOS layers were obtained by recrystallization and thinning of submicron (300 nm) SOS layers, which have various structural quality. The density of structural defects in the layers was estimated by using XRD and TEM. Full width at half maximum of rocking curves (ω-geometry) was no more than 0.19-0.20° for 100 nm ultra-thin SOS layers. The structural quality of 300 nm submicron SOS layers, which were obtained by CVD, depends on dislocation density in 100 nm ultrathin layers. The dislocation density in ultrathin SOS layers was reduced by ~1 • 104 cm-1 due to the utilization of the submicron SOS with good crystal quality. Test n-channel MOS transistors based on ultra-thin SOS wafers were characterized by electron mobility in the channel 725 cm2 V-1 s-1.

Authors: Палач З.
Published: July 2020

Оценка изотопного состава топлива – важная задача для атомной энергетики. Известно несколько основных методик по определению изотопного состава тяжелых элементов, например урана, как более точных и длительных, так и экспрессных. Для производства с большим количеством образцов оптимален метод полного испарения, обеспечивающий высокую степень автоматизации и приемлемую точность анализа. Полное испарение также позволяет снижать уровень квалификации в подготовке образцов, уменьшая тем самым погрешности в результатах. В работе проведена проверка стандартных образцов состава NBS U010, NBL U030a и NBL U050 методом полного испарения с помощью термоионизационного масс-спектрометра Phoenix (Isotopx, Велико­британия). Статистическая обработка результатов серии экспериментов показала, что по сравнению с другими метод полного испарения лучше соответствует по точности требованиям к определению изотопного отношения 235U / 238U и согласуется с литературными данными.

Abstract : Orangutan is classified as an endangered species. Forest clearance for a variety of purposes and functions over the region led to the limited habitat for orangutans. Orangutans habitat is fragmented into several regions led to the survival of a population of a species depends on habitat conditions. Performing a nest survey is important to give a deeper understanding of the ecology and help determine the best protective management measures. We provide basic data of orangutan density and orangutan nesting characteristics in protected forest area Sibongkaras village. This study was conducted in April 2019 until June 2019 in protected forest area Sibongkaras village, Pakpak Bharat. Tracking begins with observed the presence of a nest based on a purposive sampling method. And data retrieval was done by line transect method. Data analyzed at Universitas Nahdlatul Ulama Sumatera Utara. Our result showed that the orangutan population density was 0.0072 individuals/km2 or 0.72 individuals/ha. The dominant position of the nest is in a position which is a position I nest close to the main stem of the tree with the nest number 13 (43.3%). Generally, the nest is found at an altitude of  >15 meters with a sum of 27 nests (90%).Abstrak : Orangutan diklasifikasikan sebagai spesies yang terancam punah.

Melakukan survei sarang penting untuk memberikan pemahaman yang lebih dalam tentang ekologi dan membantu menentukan langkah-langkah manajemen perlindungan terbaik. Kami menyediakan data dasar kepadatan orangutan dan karakteristik sarang orangutan di kawasan hutan lindung Desa Sibongkaras. Penelitian ini dilakukan pada bulan April 2019 hingga Juni 2019 di kawasan hutan lindung Desa Sibongkaras, Pakpak Bharat. Pengamatan dimulai dengan mengamati keberadaan sarang berdasarkan metode purposive sampling. Dan pengambilan data dilakukan dengan metode transek garis. Data yang diperoleh di analisis di Universitas Nahdlatul Ulama Sumatera Utara. Hasil Penelitian kami menunjukkan kepadatan populasi orangutan di 0,0072 individuals/km2 atau 0,72 individu / ha. Posisi sarang yang dominan adalah pada posisi sarang yang berada di posisi paling dekat dengan batang utama, dengan jumlah sarang 13 (43,3%). Umumnya sarang ditemukan di ketinggian > 15 meter dengan jumlah 27 sarang (90%).

Islamic Character Education in E-Learning Model: How Should It be Implemented?
Authors: Mustofa Mutmainnah , Ahmadi Rulam , Karimullah Imam Wahyudi
Published: July 2020

Recently, studies examining the inclusion of Islamic character education in schooling sectors have been exclusively discerned. The research mainly focused on teachers’ and students’ perceptions, curriculum and materials development, as well as policy implementation. Albeit the results of these studies shared significant insights in teacher education programs, very sparse discussions were carried out with regard to how the Islamic character education should be enacted. Interestingly, virtual education nowadays also challenges the implementation of this notion. In this work, therefore, we propose a model of Islamic character education cultivation employing e-learning approach in a schooling context. The use of participatory action research (PAR), additionally, is encouraged to capture learning cycles of Islamic character in the classroom between teachers and students. This proposal, if implemented by teachers, would contribute to better realization of moderate teachings of Islam through character education.

Pregnancy recognition in ruminant affects numerous genes regulation.
Interferon-stimulatory gene (ISG15), an ubiquitin-like protein that mediates
theconjugation of different proteins through its ISGylation enzymes UBE1L
and UBCH8, is also differentially expressed during early pregnancy. The
purpose of this study was to investigate the role of ISG-15 in the
establishment of pregnancy and conceptus elongation during early post
conception periods and to ascertain the presence of ISGylation enzymes UBE1L
and UBCH8. Therefore, sheep were synchronized through cloprostenol sodium
and gonadotrophin releasing hormone-1 and serviced by rams. The blood was
collected on the post-mating days 6, 11, 12, 13, 14, 16, 17, 21, 23 and 25.
The ISG-15, UBE1L and UBCH8 primers were used to amplify the corresponding
transcriptomic region using PCR. Recovery rate of each transcriptomic
fragment was compared with the housekeeping gene GAPDH. ISG-15 expression
was higher on day 12, contrary to UBE1L were higher on day 6 and UBCH8 on
day 21. Furthermore, the ISG-15 is ubiquitin-like protein, mediates UBE1L
and UBCH8 enzymes to guard the conceptus against viral pathogenicity during
early pregnancy.
Estimates of alcohol-related mortality in Serbia (2016-2018)
Authors: Marinkovic Ivan
Published: July 2020

The impact of alcohol on mortality is not negligible, not globally and
especially not in Europe. Alcohol as a mortality factor in Serbia has not
yet been specifically analysed, chiefly due to a lack of data. The cultural
pattern and results from surrounding countries - as well as research on the
extent of alcohol consumption in Serbia - all suggest that alcohol-related
mortality represents a significant share of total mortality, especially
when it comes to men. The results of the study on alcohol abuse or excessive
consumption in this paper do not confirm that this mortality factor places a
significant burden on the population. This paper provides estimates of
alcohol-related mortality using guidelines from the World Health
Organization. Analysis of the direct impact and estimates of the indirect
impact of alcohol on mortality in Serbia (2016-2018) show that the average
number of deaths is about 2,500 annually. The number of alcohol-related
deaths is highest in the later years of life, while the proportion of
alcohol-related deaths is highest in early adulthood. Men are more likely to
consume alcohol, so their mortality is higher as a consequence. Men die from
alcohol-related causes at a rate almost four times higher than that of
women, and they have more deaths caused by alcohol than women across all
age groups. The overall alcohol-related mortality rate for men is 56.6 per
100,000, while for women it is significantly lower at 14.2 per 100,000. The
most common cause of alcohol-related mortality is in the form of digestive
system diseases (about 26% of all alcohol-related deaths in Serbia),
followed by tumours and violence (24% and 23% respectively). From region to
region (NUTS 2), significant differences in alcohol-related mortality can
be noted. Every third death due to alcohol occurs in Vojvodina, which leads
the way for both sexes. There, values for men are as much as 60% higher than
those in the Sumadija and Western Serbia regions, while those values are
about 30% higher for women. Standardised alcohol-related death rates are
highest in the north of Vojvodina, in the districts of North Backa and North
Banat (NUTS 3). Moravicki, Sumadija, and Pirot districts have values that
are about 30% lower than average for Serbia. Excessive alcohol consumption
is one of the preventable mortality factors that can be addressed with
appropriate prevention measures. Some good reasons to avoid alcohol abuse
include longer lifespan, lower likelihood of depression, significantly lower
likelihood of committing suicide, and lower likelihood of dying from liver
disease. Those who drink less are also less likely to be involved in a car
accident or have to deal with the police. When consumed in excess, alcohol
disrupts family relationships, leads to obesity, damages the brain, and
causes sexual dysfunction.
