    There has been an increase of content related to Quran and Hadith on the internet over the past few years. Diacritical Digital Quran is very sensitive to tampering. Diacritics are the symbols used beneath/above Quranic verses for reading purposes of the Quran. Minor change in diacritics can alter the meaning of a particular Quranic verse. Hence, there is a need for an authentication system to differentiate between fake and original verses. In this work, a model is proposed related to automatic authentication of Digital Quran. Authentication model is divided into two phases: tokenisation and authentication. For tokenisation, regular expressions are used to split input Quranic verse into single characters. In case of authentication, existing and standard exact matching algorithm i.e. Quick search (QS) is used. On testing the proposed model by comparing popular search engines and other related existing works, our approach is 100 % accurate in terms of full verse detection.

    Non-alcoholic fatty liver disease (NAFLD) is one of the main causes of fibrosis. Liver biopsy remains the gold standard for the confirmation of fibrosis in NAFLD patients. Effective and non-invasive diagnosis of advanced fibrosis is essential to disease surveillance and treatment decisions. Herein we used routine medical test markers and logistic regression to differentiate early and advanced fibrosis in NAFLD patients from China, Malaysia, and India (n1 = 540, n2 = 147, and n3 = 97) who were confirmed by liver biopsy. Nine parameters, including age, body mass index, fasting blood glucose, presence of diabetes or impaired fasting glycemia, alanine aminotransferase, γ-glutamyl transferase, triglyceride, and aspartate transaminase/platelet count ratio, were selected by stepwise logistic regression, receiver operating characteristic curve (ROC), and hypothesis testing and were used for model construction. The area under the ROC curve (auROC) of the model was 0.82 for differentiating early and advanced fibrosis (sensitivity = 0.69, when specificity = 0.80) in the discovery set. Its diagnostic ability remained good in the two independent validation sets (auROC = 0.89 and 0.71) and was consistently superior to existing panels such as the FIB-4 and NAFLD fibrosis score. A web-based tool, LiveFbr, was developed for fast access to our model. The new model may serve as an attractive tool for fibrosis classification in NAFLD patients.

    OBJECTIVE: The aim of this study is to ascertain the psychological impacts of coronavirus disease (COVID-19) among the Pakistani health care workers (HCWs) and their coping strategies.

    METHODS: This web-based, cross-sectional study was conducted among HCWs (N = 398) from Punjab Province of Pakistan. The generalized anxiety scale (GAD-7), patient health questionnaire (PHQ-9), and Brief-COPE were used to assess anxiety, depression, and coping strategies, respectively.

    RESULTS: The average age of respondents was 28.67 years (SD = 4.15), with the majority being medical doctors (52%). Prevalences of anxiety and depression were 21.4% and 21.9%, respectively. There was no significant difference in anxiety and depression scores among doctors, nurses, and pharmacists. Females had significantly higher anxiety (P = 0.003) and depression (P = 0.001) scores than males. Moreover, frontline HCWs had significantly higher depression scores (P = 0.010) than others. The depression, not anxiety, score was significantly higher among those who did not receive the infection prevention training (P = 0.004). The most frequently adopted coping strategies were religious coping (M = 5.98, SD = 1.73), acceptance (M = 5.59, SD = 1.55), and coping planning (M = 4.91, SD = 1.85).

    CONCLUSION: A considerable proportion of HCWs are having generalized anxiety and depression during the ongoing COVID-19 pandemic. Our findings call for interventions to mitigate mental health risks in HCWs.

    BACKGROUND: Technology, including mobile apps, has the potential to support self-management of long-term conditions and can be tailored to enhance adoption. We developed an app to support asthma self-management among people with limited health literacy in a web-based workshop (to ensure physical distancing during the COVID-19 pandemic).

    OBJECTIVE: The aim of this study is to develop and test a prototype asthma self-management mobile app tailored to the needs of people with limited health literacy through a web-based workshop.

    METHODS: We recruited participants from a primary care center in Malaysia. We adapted a design sprint methodology to a web-based workshop in five stages over 1 week. Patients with asthma and limited health literacy provided insights into real-life self-management issues in stage 1, which informed mobile app development in stages 2-4. We recruited additional patients to test the prototype in stage 5 using a qualitative research design. Participants gave feedback through a concurrent thinking-aloud process moderated by a researcher. Each interview lasted approximately 1 hour. Screen recordings of app browsing activities were performed. Interviews were audio-recorded and analyzed using a thematic approach to identify utility and usability issues.

    RESULTS: The stakeholder discussion identified four themes: individual, family, friends, and society and system levels. Five patients tested the prototype. Participants described 4 ways in which the app influenced or supported self-management (utility): offering information, providing access to an asthma action plan, motivating control of asthma through support for medication adherence, and supporting behavior change through a reward system. Specific usability issues addressed navigation, comprehension, and layout.

    CONCLUSIONS: This study proved that it was possible to adapt the design sprint workshop to a web-based format with the added advantage that it allowed the development and the testing process to be done efficiently through various programs. The resultant app incorporated advice from stakeholders, including sources for information about asthma, medication and appointment reminders, accessible asthma action plans, and sources for social support. The app is now ready to move to feasibility testing.

    The advancement of internet nowadays have drives the university students place great reliance on the internet for almost all matter. However, if the internet is heavily used, it may have a detrimental effect which could contribute to an Internet Addiction Disorders (IAD) among university students. IAD could create problem in developing relationships like normal people and appear to have low quality of memory. Thus, this is definitely not good to students. Knowing that by listening to Quran verse has a potential to improve the memory, hence this study is carried out. The study utilized a brain-computer interface Emotiv EPOC+, multichannel electroencephalography (EEG) detection during dual N-back tasks (spatial and verbal) where subjects were given with load level from 2-back to 3-back. Five (5) out of two hundred (200) participants of USIM’s students (20-23 years old) were recruited to continue with the brain scan experiment after getting a high score which indicated their severe level of addiction in a screening addiction test, Young’s Internet Addiction Test. Subjects were administered with a pre‐ and post‐tests to analyze and evaluate the effects of implementing Quran listening in their dailies for two months. The behavioral assessment exhibited accuracy increment between pre- and post- tests by 13.4% from 9.4%. While the EEG power value showed there were significant differences (p=0.002) in brainwaves between the pre- and the post- tests for 2 back; as the dominant brainwave found at the frontal and prefrontal cortex for delta and theta bands. The research revealed that the theta power band presented as the most dominant brain wave associated with N-back task for the enhancement of working memory which influence by the listening to Surah in Al-Quran.

    Compared with females, little research on muscularity and the sociocultural influences on this domain has been conducted with males in non-Western societies. The current study explored these sociocultural predictors of drive for muscularity among Malaysian male college students, specifically in terms of ethnicity and exposure to media (i.e., Internet and social media). In total, 166 male college students from two universities in Kuala Lumpur were asked to rate the questionnaires as to muscularity-oriented attitudes and behaviours. Multivariable general linear model analyses revealed that being Chinese was a strong predictor of muscularity-oriented attitudes and behaviours. In addition, modern media, particularly, Internet use and the number of followers on Instagram, was found to significantly predict males' drive for muscularity. Overall findings suggest that males of particular ethnic groups may be at higher risk for negative body image compared to the other ethnic populations and modern media use may accelerate drive for muscularity, which may also in turn place males at higher risk for excess muscularity-oriented thoughts and behaviours.

    Objective: A paradigm shift towards a PBL bidirectional dialogic feedback can enhance learners' performance. This study aimed to investigate undergraduate medical students' perceptions of their PBL feedback.

    Methods: We sent e-mail invitations to a web-based survey to year one and two students at College of Medicine, King Saud University. Items included the process, content, and benefits of PBL feedback.

    Results: Of 209 respondents, 110 (53%) were first and 99 (47%) were second-year students. About 50% agreed that the feedback was regularly provided at scheduled timing and 72% perceived feedback environment as non-threatening. Agreement rates that the tutors asked students first to assess their performance, tell them what went well, what the areas for improvement are and develop with them an improvement plan were 59%, 61%, 61% and 52%, respectively. 61% agreed that tutors judged performance not personality. More year one students significantly agreed that the PBL feedback helped them to improve their knowledge acquisition and non-technical skills.

    Conclusion: Many of our PBL tutors have started the shift to a dialogic bi-directional feedback. We recommend continuing the faculty development efforts, peer-reviewing, and seeking student's feedback within the academic quality satisfaction surveys.

    Because students' ability to use statistics, which is mathematical in nature, is one of the concerns of educators, embedding within an e-learning system the pedagogical characteristics of learning is 'value added' because it facilitates the conventional method of learning mathematics. Many researchers emphasize the effectiveness of cognitive apprenticeship in learning and problem solving in the workplace. In a cognitive apprenticeship learning model, skills are learned within a community of practitioners through observation of modelling and then practice plus coaching. This study utilized an internet-based Cognitive Apprenticeship Model (i-CAM) in three phases and evaluated its effectiveness for improving statistics problem-solving performance among postgraduate students. The results showed that, when compared to the conventional mathematics learning model, the i-CAM could significantly promote students' problem-solving performance at the end of each phase. In addition, the combination of the differences in students' test scores were considered to be statistically significant after controlling for the pre-test scores. The findings conveyed in this paper confirmed the considerable value of i-CAM in the improvement of statistics learning for non-specialized postgraduate students.

    Geographical Information Systems (GIS) and three dimensional (3D) World Wide Web (WWW) applications usage are on the rise. The demand for online 3D terrain visualization for GIS data has increased. Current users demand for more complex data which have higher accuracy and realism. This is aided by the emergence of geo-browsers in the market which provide free service and also cater for the commercialized market. Other new technology driving the market is the use of software such as CityGML, Virtual Reality Markup Language (VRML)/ Entensive 3D (X3D), geoVRML, and Keyhole Markup Language (KML). These technologies also play an important role for this new era of online 3D terrain visualization. The aim of this paper is to implement the online 3D terrain visualization for GIS data by using VRML technology and launching the system into three different web servers. The data used for this system are contour data and high resolution satellite image (QUICKBIRD) for Universiti Putra Malaysia (UPM) area. Testing was done only for satellite image overlaid to 3D terrain data. The web servers used in this experiment were the Spatial Research Group Server in UPM, Universiti Utara Malaysia (UUM) web server, and ruzinoor.my web server. The comparison was based on the performance of web servers in terms of accessibility, uploading time, CPU usage, frame rate per second (fps), and number of users. The results from this experiment will be of help and guidance to the developers in finding the right web servers for the best performance on implementing online 3D terrain visualization for GIS data.

    Introduction: Internet addiction is an increasingly worrying phenomena affecting people globally especially the youths. This study aimed to determine the prevalence of internet addiction among undergraduate students in a Malaysian public university and its associated factors. Materials and Methods: A cross-sectional study involving 322 undergraduate students, identified through cluster sampling was conducted using a pretested, self-administered questionnaire. The questionnaire includes socio-demography, use of information technology gadgets and internet usage. Internet Addiction test (IAT) was used to identify internet addiction. Data was analysed using SPSS version 22. Results: From 322 respondents, 25 (7.8%) were categorised as addictive internet users, while 182 (56.5%) were problematic internet users. The commonest online activity includes social networking (86.6%), entertainment (77.3%) and educational purposes (77.0%). From multivariate analysis, problematic and addictive internet use was significantly more common among male students (AOR=2.47, 95% CI [1.43, 4.26]), those who received study loan (AOR=1.93, 95% CI [1.10, 3.39]) and other types of funding (AOR=3.95, 95% CI [1.59, 9.80]) compared to those on scholarships, and those who spent between four to ten hours a day accessing the Internet (AOR=2.43, 95% CI [1.13, 5.23]) compared to those using the Internet for two hours or less a day. Conclusion: The prevalence of problematic and addictive internet use among respondents were higher compared to previous researches among Malaysian adolescents. It is recommended that an awareness programme on responsible use of the internet be conducted to prevent students from becoming addicted which may impact negatively on their educational performance and social life.

    The management of a chemical inventory is necessary for safety purposes as well as for fulfilling regulatory compliance. In most academic laboratories, the management of chemicals is still being done manually, which is time-consuming. As a result, data are not updated and expired chemicals are unintentionally used. This research proposes that UHF Class 1 Gen 2 Radio Frequency Identification (RFID) technology be used in the development of a chemical inventory information system to ease chemical tracking as well as to shorten the inventory process time. An information system integrating RFID data and a web-based rule identification interface was developed. WAMP 2.2.17, PHP 5.3.5 and MySQL 5.5.8 were downloaded and a programming language was written to check the expiration date of the chemicals as well as to produce alert notification status. Wireless technology through GSM modem helped in producing alert messages using the Short Message System (SMS) of the nearly expired chemicals to the handphone of the person in charge in real time.

    In the near future, the Internet of Vehicles (IoV) is foreseen to become an inviolable part of smart cities. The integration of vehicular ad hoc networks (VANETs) into the IoV is being driven by the advent of the Internet of Things (IoT) and high-speed communication. However, both the technological and non-technical elements of IoV need to be standardized prior to deployment on the road. This study focuses on trust management (TM) in the IoV/VANETs/ITS (intelligent transport system). Trust has always been important in vehicular networks to ensure safety. A variety of techniques for TM and evaluation have been proposed over the years, yet few comprehensive studies that lay the foundation for the development of a "standard" for TM in IoV have been reported. The motivation behind this study is to examine all the TM models available for vehicular networks to bring together all the techniques from previous studies in this review. The study was carried out using a systematic method in which 31 papers out of 256 research publications were screened. An in-depth analysis of all the TM models was conducted and the strengths and weaknesses of each are highlighted. Considering that solutions based on AI are necessary to meet the requirements of a smart city, our second objective is to analyze the implications of incorporating an AI method based on "context awareness" in a vehicular network. It is evident from mobile ad hoc networks (MANETs) that there is potential for context awareness in ad hoc networks. The findings are expected to contribute significantly to the future formulation of IoVITS standards. In addition, gray areas and open questions for new research dimensions are highlighted.

    The explosive growth of social networks in recent times has presented a powerful source of information to be utilized as an extra source for assisting in the social recommendation problems. The social recommendation methods that are based on probabilistic matrix factorization improved the recommendation accuracy and partly solved the cold-start and data sparsity problems. However, these methods only exploited the explicit social relations and almost completely ignored the implicit social relations. In this article, we firstly propose an algorithm to extract the implicit relation in the undirected graphs of social networks by exploiting the link prediction techniques. Furthermore, we propose a new probabilistic matrix factorization method to alleviate the data sparsity problem through incorporating explicit friendship and implicit friendship. We evaluate our proposed approach on two real datasets, Last.Fm and Douban. The experimental results show that our method performs much better than the state-of-the-art approaches, which indicates the importance of incorporating implicit social relations in the recommendation process to address the poor prediction accuracy.

    The investments and costs of infrastructure, communication, medical-related equipments, and software within the global healthcare ecosystem portray a rather significant increase. The emergence of this proliferation is then expected to grow. As a result, information and cross-system communication became challenging due to the detached independent systems and subsystems which are not connected. The overall model fit expending over a sample size of 320 were tested with structural equation modelling (SEM) using AMOS 20.0 as the modelling tool. SPSS 20.0 is used to analyse the descriptive statistics and dimension reliability. Results of the study show that system utilisation and system impact dimension influences the overall level of services of the healthcare providers. In addition to that, the findings also suggest that systems integration and security plays a pivotal role for IT resources in healthcare organisations. Through this study, a basis for investigation on the need to improvise the Malaysian healthcare ecosystem and the introduction of a cloud computing platform to host the national healthcare information exchange has been successfully established.

    Postquantum cryptography for elevating security against attacks by quantum computers in the Internet of Everything (IoE) is still in its infancy. Most postquantum based cryptosystems have longer keys and signature sizes and require more computations that span several orders of magnitude in energy consumption and computation time, hence the sizes of the keys and signature are considered as another aspect of security by green design. To address these issues, the security solutions should migrate to the advanced and potent methods for protection against quantum attacks and offer energy efficient and faster cryptocomputations. In this context, a novel security framework Lightweight Postquantum ID-based Signature (LPQS) for secure communication in the IoE environment is presented. The proposed LPQS framework incorporates a supersingular isogeny curve to present a digital signature with small key sizes which is quantum-resistant. To reduce the size of the keys, compressed curves are used and the validation of the signature depends on the commutative property of the curves. The unforgeability of LPQS under an adaptively chosen message attack is proved. Security analysis and the experimental validation of LPQS are performed under a realistic software simulation environment to assess its lightweight performance considering embedded nodes. It is evident that the size of keys and the signature of LPQS is smaller than that of existing signature-based postquantum security techniques for IoE. It is robust in the postquantum environment and efficient in terms of energy and computations.

    BACKGROUND: Diabetes is becoming a very important health issue in rapidly developing nations and there is an urgent need to improve overall diabetes self-management education in these countries. Although e-health is an emerging theme, only a few successful web-based studies on diabetes self-management have been reported.
    PURPOSE: We describe the development, implementation, and process evaluation of an Internet-delivered dietary intervention program (myDIDeA) for diabetic patients in a developing country.
    METHOD: Specific dietary components to be included in the intervention module were first identified through a comprehensive review of literature and guidelines. The lesson plans and the study website were then developed based on the evidence, Transtheoretical Model's Stages of Change and user-centered design approach. Finally, the effectiveness of the website was tested through a randomized-controlled trial to promote dietary change in patients with type 2 diabetes. The participants in the intervention group (n = 66) were given access to myDIDeA for 6 months. Process evaluation in form of intervention adherence and program reception were conducted at post intervention.
    RESULTS: The response rate for the process evaluation was 89%. On average, each participant logged in at least once for each lesson plan and spent almost 12 min on the site. The participants' content satisfaction, acceptability, and usability scores were satisfactory. The primary outcome of the trial, Dietary Knowledge, Attitude, and Behavior score was strongly correlated with content satisfaction (r = 0.826, p Internet-based intervention programs to other health behaviors and issues related to self-management of chronic conditions. In addition, interactivity, peer support via social media, and other means to stimulate the interest of participants can be explored.
