Published: June 2023

Đã có nhiều bằng chứng về mắc đái tháo đường ở người nhiễm SARS-COV-2 sau giai đoạn cấp. Tuy nhiên nguy cơ phát triển mới đái tháo đường ở giai đoạn hậu COVID-19 chưa được biết đầy đủ. Trong bài tổng quan này chúng tôi trình bày chứng cứ đã được báo cáo về mắc mới bệnh đái tháo đường sau COVID-19 ở người bệnh nhẹ lẫn nặng phải nhập viện. Trong tương lai chắc chắn cần có thêm nhiều nghiên cứu về ảnh hưởng của SARS-COV-2 trên nồng độ glucose và HbA1c có theo dõi liên tục theo thời gian để hiểu đầy đủ tiến triển của bệnh đái tháo đường hậu COVID.

Abstract

There is growing evidence suggesting that beyond the acute phase of SARSCOV-2 infection, patients could experience diabetes. However, the risks of new - onset diabetes in the post - acute phase have not yet been comprehensively characterized. In the review, we summarized the reported evidence of diabetes incidence after COVID-19 in individuals with mild disease in primary careorwith more severe disease in hospital settings. Future studies should investigate the effects of SARS-COV-2 infection on glucose and HbA1c levels on a continuous scale in order to fully understand the progression of post - COVID diabetes.
IMPLEMENTASI WAKAF UANG PADA MASA KESULTANAN UTSMANIYAH

ABSTRACT

Waqf has an important role in Islamic society from ancient times to the present. The scope of waqf assets has grown to the point of cash waqf. During the Ottoman Empire, waqf was a practice that was widely practiced by philanthropists to help others. Then this practice expanded to a wider range of cash waqf. The concept of waqf used is to lease waqf assets and take profits in accordance with sharia principles. This cash waqf was then managed into a legal and strict waqf system, so that the cash waqf during the Ottoman Empire was not only for the welfare of the community but also the support for the country's economy.

Published: June 2023

This study sought to find out how the media covered terrorism acts in Uganda during the year 2010. Whether the media coverage affected the image and operations of security agencies and what would be the best strategies for the media to adopt in covering terrorism acts in Uganda. It is also based on four main theories of Violence, Terrorism, Media and Framing in relation to security and terrorism. The study adopted content analysis and interviews as the main methods of collecting data. It started with library research where most of the relevant literature was obtained. It was followed by archival research at New Vision, Monitor and Red Pepper newspapers library at their headquarters in Kampala. All the newspapers of 2010 were perused and vital information compiled for the final report. Interview guides were also administered to key informants from the media and security personnel that provided crucial information. The findings indicate that disconnection between security agencies and the media is caused by the gaps which exist about knowledge of each other’s roles and interests. The journalists have little knowledge about terrorism, their interests, operations and the close relationship between the media and terrorism. The study makes a number of recommendations that may be useful to all stakeholders in Uganda in the war against terrorism. Joint training, respect and following the ethical and code of conduct, timely and accurate sharing of information, enacting ring laws, and having respect to each other’s roles and the existing laws.
Teachers’ Use of Instructional Materials in the Teaching and Learning of Mathematics in private Secondary Schools of Gasabo District, Rwanda
Authors:   University of Rwanda, Mugisha Enock , Uworwabayeho Alphonse , Urwibutso Amina
Published: June 2023

The use of instructional materials makes the teaching and learning of mathematics simpler, more engaging, more enjoyable, and more closely connected to real-world applications. This study explored the teachers’ use of instructional materials in the teaching and learning of mathematics in private secondary schools in the Gasabo district, Rwanda. A case study research design under the qualitative method was employed. The convenience sampling technique was used to select five private secondary schools while the purposive sampling technique was adopted to select two teachers from the five private secondary schools in the Gasabo district, Rwanda. Self-administered questionnaires and classroom observations of ten mathematics teachers from the five schools were used for data collection. The collected data was read and reread, edited, and coded for easy interpretation and understanding in assessing its qualitative accuracy. The findings indicated that most instructional materials are available. However, the most ones used are textbooks and writing materials. The analysis of the classroom observations in relation to the sociocultural theory and Gagnes’ theory of instructional design revealed that most mathematics teachers used instructional materials as a way of presenting new content more memorable and meaningful to the learners. However, some teachers did not allow students to actively interact with the materials, and thus, students were not given the opportunity to enhance their active learning and participate in constructing their knowledge of the mathematics content. Based on the conclusion of this study, it is recommended that teachers should be creative enough to improvise simple instructional materials to spice up their teaching and not to prove unconcerned on the premise of unavailable or inadequate instructional materials. In-service training programs on instructional material utilization should be organized by school leaders to enable teachers to gain more knowledge on the use of instructional materials in the teaching and learning process.

Authors:   University of Rwanda, Kabalisa Janvier
Published: June 2023

The abstract and microscopic character of some physics concepts, make it difficult for pupils to acquire them conceptually. The current study sought to determine how engineering students' conceptual grasp of electromagnetism was affected by learning through real-life application-based classroom activities. Seventy-three (73) students successfully completed the study at IPRC Huye, with 35 in the experimental group and 38 in the control group. In experimental group, the teaching intervention used real-world applications, whereas the control got conventional instruction. Two physics teachers gave lectures on magnetostatics, current electricity, electrostatics, and electromagnetic induction. The conceptual assessment of electricity and magnetism. Independent sample t-test and normalized learning gain were all used in the analysis. Mean mark in pre-test for both control and experimental group are 31.5 and 33.5 respectively and significant value p=0.679 which meant that there was no significant different in conceptual understanding between the groups before the treatment. The mean mark after treatment was found to be 52.44 and 68.5 respectively and significant value p= 0.00 which indicated that there was a significant different in conceptual understanding of electromagnetism between control and experimental group after intervention. Despite being both categorized as being in the medium category, the major findings showed that students in the experimental group increased their conceptual knowledge of electromagnetism more than those in the control group (g_av=0.520>g_av=0.31).The findings of this study concluded that hands-on exercises that linked ideas of electricity and magnetism were noted as the most interesting by students and physics teachers.
Differences in learning retention and experience of augmented reality notes compared to traditional paper notes in a chiropractic technique course: A randomized trial
Authors: Cade Alice E. , Stevens Kirk , Lee Alan , Baptista Lisa
Published: June 2023

Objective

To investigate if a written guide or augmented reality (AR) guide improves free recall of diversified chiropractic adjusting technique and to capture participants' impressions of the study in a poststudy questionnaire.

Methods

Thirty-eight chiropractic students were evaluated for diversified listing (a nomenclature denoting vertebral malposition and correction) recall, pre-AR and post-AR, or written guide review. The vertebral segments used were C7 and T6. Two randomized groups reviewed an original course written guide (n = 18) or a new AR guide (n = 20). A Wilcoxon-Mann-Whitney (C7) and t test (T6) compared group differences in reevaluation scores. A poststudy questionnaire was given to capture participants' impressions of the study.

Results

Both groups showed no significant differences in free recall scores after reviewing the guides for C7 or T6. The poststudy questionnaire suggested a number of strategies could be used to improve current teaching material such as more detail in the written guides and organizing content into smaller blocks.

Conclusion

Use of an AR or written guide does not seem to change participants' free recall ability when used to review diversified technique listings. The poststudy questionnaire was useful to identify strategies to improve currently used teaching material.

Importance

MET inhibitors have recently demonstrated clinical activity in patients with MET exon 14 (METex14)-skipping non–small cell lung cancer (NSCLC); however, data with longer follow-up and in larger populations are needed to further optimize therapeutic approaches.

Objective

To assess the long-term efficacy and safety of tepotinib, a potent and highly selective MET inhibitor, in patients with METex14-skipping NSCLC in the VISION study.

Design, Setting, and Participants

The VISION phase 2 nonrandomized clinical trial was a multicohort, open-label, multicenter study that enrolled patients with METex14-skipping advanced/metastatic NSCLC (cohorts A and C) from September 2016 to May 2021. Cohort C (>18 months’ follow-up) was an independent cohort, designed to confirm findings from cohort A (>35 months’ follow-up). Data cutoff was November 20, 2022.

Intervention

Patients received tepotinib, 500 mg (450 mg active moiety), once daily.

Main Outcomes and Measures

The primary end point was objective response by independent review committee (RECIST v1.1). Secondary end points included duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety.

Results

Cohorts A and C included 313 patients (50.8% female, 33.9% Asian; median [range] age, 72 [41-94] years). The objective response rate (ORR) was 51.4% (95% CI, 45.8%-57.1%) with a median (m)DOR of 18.0 (95% CI, 12.4-46.4) months. In cohort C (n = 161), an ORR of 55.9% (95% CI, 47.9%-63.7%) with an mDOR of 20.8 (95% CI, 12.6-not estimable [NE]) months was reported across treatment lines, comparable to cohort A (n = 152). In treatment-naive patients (cohorts A and C; n = 164), ORR was 57.3% (95% CI, 49.4%-65.0%) and mDOR was 46.4 (95% CI, 13.8-NE) months. In previously treated patients (n = 149), ORR was 45.0% (95% CI, 36.8%-53.3%) and mDOR was 12.6 (95% CI, 9.5-18.5) months. Peripheral edema, the most common treatment-related adverse event, occurred in 210 patients (67.1%) (35 [11.2%] experienced grade ≥3 events).

Conclusions and Relevance

The findings from cohort C in this nonrandomized clinical trial supported the results from original cohort A. Overall, the long-term outcomes of VISION demonstrated robust and durable clinical activity following treatment with tepotinib, particularly in the treatment-naive setting, in the largest known clinical trial of patients with METex14-skipping NSCLC, supporting the global approvals of tepotinib and enabling clinicians to implement this therapeutic approach for such patients.

Preventing islet β‐cells death is crucial for treating type 2 diabetes mellitus (T2DM). Currently, clinical drugs are being developed to improve the quality of T2DM care and self‐care, but drugs focused on reducing islets β‐cell death are lacking. Given that β‐cell death in T2DM is dominated ultimately by excessive reactive oxygen species (ROS), eliminating excessive ROS in β‐cells is a highly promising therapeutic strategy. Nevertheless, no antioxidants have been approved for T2DM therapy because most of them cannot meet the long‐term and stable elimination of ROS in β‐cells without eliciting toxic side‐effects. Here, it is proposed to restore the endogenous antioxidant capacity of β‐cells to efficiently prevent β‐cell death using selenium nanodots (SENDs), a prodrug of the antioxidant enzyme glutathione peroxidase 1 (GPX1). SENDs not only scavenge ROS effectively, but also “send” selenium precisely to β‐cells with ROS response to greatly enhance the antioxidant capacity of β‐cells by increasing GPX1 expression. Therefore, SENDs greatly rescue β‐cells by restoring mitophagy and alleviating endoplasmic reticulum stress (ERS), and demonstrate much stronger efficacy than the first‐line drug metformin for T2DM treatment. Overall, this strategy highlights the great clinical application prospects of SENDs, offering a paradigm for an antioxidant enzyme prodrug for T2DM treatment.

Journal master lists for Web of Science, Scopus, and CrossRef were searched for the African journals. A total of 2,229 unique active African journals were identified from Ulrich (N = 2,117, 95.0%) and AJOL (N = 243, 10.9%) after removing duplicates. The volume of African journals in Web of Science and Scopus databases is 7.4% (N = 166) and 7.8% (N = 174), respectively, compared to the 45.6% (N = 1,017) covered in CrossRef. While making up only 17.% of all the African journals, South African journals had the best coverage in the two most authoritative databases, accounting for 73.5% and 62.1% of all the African journals in Web of Science and Scopus, respectively. In contrast, Nigeria published 44.5% of all the African journals. The distribution of the African journals is biased in favor of Medical, Life and Health Sciences and Humanities and the Arts in the three databases. The low representation of African journals in CrossRef, a free indexing infrastructure that could be harnessed for building an African‐centric research indexing database, is concerning.
The design and evaluation of a nudge‐based interface to facilitate consumers' evaluation of online health information credibility
Authors: Zhang Yan , Liu Jiaying , Song Shijie
Published: June 2023

Evaluating the quality of online health information (OHI) is a major challenge facing consumers. We designed PageGraph, an interface that displays quality indicators and associated values for a webpage, based on credibility evaluation models, the nudge theory, and existing empirical research concerning professionals' and consumers' evaluation of OHI quality. A qualitative evaluation of the interface with 16 participants revealed that PageGraph rendered the information and presentation nudges as intended. It provided the participants with easier access to quality indicators, encouraged fresh angles to assess information credibility, provided an evaluation framework, and encouraged validation of initial judgments. We then conducted a quantitative evaluation of the interface involving 60 participants using a between‐subject experimental design. The control group used a regular web browser and evaluated the credibility of 12 preselected webpages, whereas the experimental group evaluated the same webpages with the assistance of PageGraph. PageGraph did not significantly influence participants' evaluation results. The results may be attributed to the insufficiency of the saliency and structure of the nudges implemented and the webpage stimuli's lack of sensitivity to the intervention. Future directions for applying nudges to support OHI evaluation were discussed.
Common mode conductive noise cancellation for multiphase converter using auxiliary winding
Authors: Sasaki Mamoru , Imaoka Jun , Yamamoto Masayoshi , Nakano Akira , Fuse Koji
Published: June 2023

A multiphase DC‐DC converter consisting of a coupled inductor and fast switching devices enables power electronics equipment to achieve a high‐power density. However, with such devices, the fast voltage transition generates substantial common mode (CM) noise. However, there are very few studies on CM noise reduction for multiphase converters using a coupled inductor. Therefore, in this paper, a CM noise reduction method is proposed for a multiphase DC‐DC converter that hardly lowers the power density.

Production systems are characterized by static configurations and slow adaption to changing requirements. They no longer meet current trends in mutability and dynamic adaptation. Software-defined Manufacturing (SDM) like other software-defined approaches leverages abstraction of hardware to achieve higher flexibility. Based on abstracted hardware, software defines desired functionalities. Requirements from the Operational Technology (OT), especially determinism, must be combined with the flexibility and interoperability of Information Technology (IT). This paper proposes a stack that enables the implementation of SDM based on a requirements analysis. It covers the main phases of the life cycle of automation applications and additional requirements from SDM. We derive the necessary components while resorting to existing approaches whenever possible. Means for applications engineering, configuration, deployment, and orchestration, as well as execution at run time, are developed.
Influence of the Joining Force on the Nugget Diameter During Resistance Spot Welding of Aluminum Materials
Authors: Pestka Jonas , Weihe Stefan
Published: June 2023

Ever new requirements for the environmental compatibility and safety of products do not stop at the automotive industry. This results in ever shorter time windows for the pre-series processes. For this reason, time-consuming preliminary tests must be minimized to ensure an accelerated start-up and production that is as trouble-free as possible. This maxim applies to all parts of the production of an automobile, but especially to the body shop, where just-in-time production has been the norm for years and any downtimes are particularly severe. In order to meet these requirements, it is advantageous to understand or predict the result of a production process as well as possible.

This paper deals with resistance spot welding of aluminum and aims to generate knowledge about the relationship between setting parameters and target value. Since resistance spot welding has a large number of setting parameters and a comprehensive investigation of these would go beyond the scope of this study, the focus is on the joining force and the features to be generated from it. The target parameter is the nugget diameter of the joining points. The data are determined experimentally and evaluated with the help of Machine Learning (ML) approaches. The correlations are presented in graphical form. The quantification of the influence of the joining force on the nugget diameter is expected to lead to a reduction of tests and thus to a gain in time.
Towards an Automated System for Robot Assembly Cell Layout Optimization
Authors: Beck Joshua
Published: June 2023

The manufacturing industry is exposed to various challenges: Increasing competition from companies abroad, the growing unpredictability and volatility of markets, and rising customer demands forcing manufacturers to be highly flexible and offer low-cost products. Using simulation tools, productions systems can be planned and analyzed before the deployment in the field, reducing the commissioning of named systems and avoiding cost-intensive errors. However, manual generation and validation of simulation models is a tedious task and demands expert knowledge of the planners about the simulations tools used. Automated generation of simulation models promises to reduce further commissioning time, making simulation tools more cost-effective. This paper compares existing approaches for 3D simulation generation and/or validation and further presents a concept for automated generation of a 3D model of a robot cell, creating a simulation and validating the processes taking place with minimum user intersection to accelerate robot cell commissioning. This is done by combining layout information with assembly related information extracted directly from 3D product model.

Published: June 2023

Due to ever faster changing market requirements, industrial production equipment needs to become much more flexible. For this reason, the Institute of Mechanical Handling and Logistics and the Institute of Electrical Energy Conversion are developing versatile, automated, and easily adaptable solutions to increase the flexibility of future intralogistics systems. As part of the ANTS 4.0 research project, a modular low-cost automated guided vehicle has been created, which breaks down the flow of goods into its smallest units: A small load carrier. The vehicle is prepared to be charged inductively and guided by color coded LED strips inside the floor, controlled from a superordinated artificial intelligence algorithm. In case of finding an obstacle by the object detection integrated in the floor, the route is recalculated and adapted in real-time.
Performance Comparison of Supervised and Reinforcement Learning Approaches for Separating Entanglements in a Bin-Picking Application

Published: June 2023

Machine Learning helps to separate entanglements in Bin-Picking Applications. The goal is to create a system that finds a path to separate an entanglement, starting from a single visual input. To realize such a system both supervised and reinforcement learning methods can be implemented. For both of these approaches we set up a motion model and the remaining properties of the real robot cell are implemented in a simulation scene. While the simulation scene can be used to create training data for the supervised learning approach, it is also the learning environment for the reinforcement learning model. Therefore, there are similar premises for comparing the two models. What needs to be investigated is which of the two methods separates the most entanglements and offers the least setup effort. The setup effort in general and the performance are examined for both approaches in simulation and also in real-world experiments. The reinforcement learning model outperforms both of the supervised learning models in the setup effort and the separation rate by over 15 percent points.

Published: June 2023

To achieve a high overall equipment effectiveness in a manufacturing process, reducing the number of defective units is crucial. It is therefore vital to identify the root causes of defects to be able to rectify them. However, the analysis of defective units can be a time-consuming and costly task.

By using machine learning, we can leverage data of the manufacturing process, like process states and different measurement values, to identify the root causes for the defects. We propose to use this data as features for the classification of a unit as defective or as belonging to a specific defect class. We can then identify the root causes for the defects by calculating the importance of the features.

In this paper, we compare our feature-based approach with deep learning methods based on the attention mechanism. The evaluation of our approach on data of a complex production process shows, that our approach clearly outperforms the deep learning methods. It also revealed the challenges in the collection of meaningful data
Enabling Single-Sensor Simultaneous Condition Monitoring of Several Vibration-Emitting Machine Parts Using Neural Networks

Published: June 2023

In production environments, monitoring the vibration of a machine or parts thereof can yield important information about the condition of the machine. The most common recommendation for vibration-based condition monitoring is to place a vibration sensor on each part of interest. These vibration sensors usually output preprocessed data, for example the root mean square value of a predefined time window.

We propose to use machine learning to simultaneously monitor several vibration-emitting machine parts using only one single vibration sensor. Due to the superposition of multiple vibrations, this is not feasible using preprocessed sensor data. Our approach therefore consists of a one-dimensional convolutional neural network, which uses the raw vibration signal as input to classify the status of the monitored machine parts.

As a first proof of concept, we monitored the status of three different motors. Using our approach, we were able to detect, which motors were running at a given time with high accuracy. We were able to significantly improve the classification results by transforming the raw data into the frequency domain. Our results are promising and show, that monitoring several vibration-emitting machine parts at the same time using only one vibration sensor is feasible.
