    Fifth-generation (5G) networks offer high-speed data transmission with low latency, increased base station volume, improved quality of service (QoS), and massive multiple-input-multiple-output (M-MIMO) channels compared to 4G long-term evolution (LTE) networks. However, the COVID-19 pandemic has disrupted the achievement of mobility and handover (HO) in 5G networks due to significant changes in intelligent devices and high-definition (HD) multimedia applications. Consequently, the current cellular network faces challenges in propagating high-capacity data with improved speed, QoS, latency, and efficient HO and mobility management. This comprehensive survey paper specifically focuses on HO and mobility management issues within 5G heterogeneous networks (HetNets). The paper thoroughly examines the existing literature and investigates key performance indicators (KPIs) and solutions for HO and mobility-related challenges while considering applied standards. Additionally, it evaluates the performance of current models in addressing HO and mobility management issues, taking into account factors such as energy efficiency, reliability, latency, and scalability. Finally, this paper identifies significant challenges associated with HO and mobility management in existing research models and provides detailed evaluations of their solutions along with recommendations for future research.

    Sharing of knowledge through Continuing Medical Education (CME) contribute immensely to professional development of skills in clinical medical practice. Thus, the writing of CME articles should adopt an approach that addresses the needs of the readers by attempting to fill gaps in their knowledge, skills, and ethics about clinical care. As such CME articles should be comprehensive and focused on specific areas. The specific learning outcomes should be well defined. In designing and development of such articles, pedagogic principles are to be borne in mind. In this article we outline a guide to writing a CME article, incorporating both the principles of instructional design and directed selflearning. The ideal CME articles will transit through multimedia-enhanced interactive online learning, with greater use of connectivity through the internet. Synchronous and asynchronous learning is in greater need, as distance and online learning are increasingly popular. Authors of CME articles will need to eventually design CME articles to be interactive, enriched with multimedia to engage their readers. Lesson plans employing instructional design principles should aim to promote both instructions for learning and formative assessment ensuring learning have taken place, and outcomes have been achieved. This article describes on how to write effective CME articles for medical journals.

Thus this study aimed to explore the feasibility of Digital Memory Album (DMA) to support reminiscence work and subsequently evaluate the psychosocial benefits of the DMA system for older adults with dementia living in community. Method: This was an exploratory case study involved five participants with mild to moderate dementia and their primary caregivers. Each participant had an opportunity to review their own life history using Life Review Experience Form (LREF) with the researcher for 8 consecutive weeks in which subsequently facilitated in development of a personalised digital life story. Caregivers provided additional information to support the development of DMA. The whole process was audio recorded. The digital life story was presented in multimedia format and displayed using the DMA. The DMA was given to the participants for review. Qualitative data was collected using semi structure questions with the participants and caregivers immediately after the completion of DMA and 6 weeks after having the DMA as a gift. Results: Analysis of the audio-records and interview data indicated that DMA promoted psychosocial wellbeing which included enjoyment, comfort, stimulate long term memory and enhanced communication and social interactions with family members and friends. Caregivers expressed the DMA helped them in recollecting the past and better understanding of their loved ones. It also reoriented their focus on their loved ones from their disability to the remaining strength. Conclusion: For the first time, this study demonstrates the feasibility of using DMA in improving the psychosocial wellbeing for people with dementia in Malaysia.

    Objective: This study aims to develop, validate and determine the reliability of an interactive multimedia strategy
    to prevent tobacco use among the young (TUPY-S) from an adolescents’ perspective. Methods: A descriptive study
    design was utilized. A modular instruction guideline by Russel (1974) was followed in the entire process, comprising
    a feasibility study, a review of existing modules, specification of the objectives, identification of the construct criterion
    items, learner analysis and entry behavior specification, establishment of the sequence instruction and media selection,
    a tryout with students and a field test. Result: Feasibility was agreed among the researchers and the school authorities.
    Culturally suitable rigorously developed tobacco use preventive strategies delivered using information technology (IT)
    are lacking in the literature. The objective of TUPY-S is to prevent tobacco use among adolescents living in Malaysia.
    Identified construct criterion items include knowledge, attitude, intention to use, self-efficacy, and refusal skill. The target
    population was early adolescents belonging to generation-Z. Content was developed from the adolescents’ perspective
    and delivered using IT in Malay language. Content validity, assessed by six experts in the field and module development,
    was good at 86%. The students’ tryout showed satisfactory face validity subjectively and objectively (85.5%) and
    high alpha Cronbach reliability (0.91). Conclusion: TUPY-S was confirmed to suit early adolescents of the current
    generation living in Malaysia. It demonstrated good content validity among the experts, satisfactory face validity and
    reliability among the target population. TUPY-S is ready to be evaluated for its effectiveness among early adolescents.

    Telehealth refers to the integration of information, telecommunication, human-machine interface technologies and health technologies to deliver health care, to promote the heath status of the people and to create health. The Malaysian Telehealth Application will, on completion, provide every resident of the country an electronic Lifetime Health Record (LHR) and Lifetime Health Plan (LHP). He or she will also hold a smart card that will contain a subset of the data in the Lifetime Health Record. These will be the means by which Malaysians will receive "seamless continuous quality care" across a range of health facilities and health care providers, and by which Malaysia's health goal of a nation of "healthy individuals, families and communities" is achieved. The challenges to security and privacy in providing access to an electronic Lifetime Health Record at private and government health facilities and to the electronic Lifetime Health Plan at homes of consumers require not only technical mechanisms but also national policies and practices addressing threats while facilitating access to health data during health encounters in different care settings. Organisational policies establish the goals that technical mechanisms serve. They should outline appropriate uses and access to information, create mechanisms for preventing and detecting violations, and set sanctions for violations. Some interesting innovations have been used to address these issues against the background of the launching of the multimedia supercorridor (MSC) in Malaysia.

    Transmission opportunity (TXOP) is a key factor to enable efficient channel bandwidth utilization over wireless campus networks (WCN) for interactive multimedia (IMM) applications. It facilitates in resource allocation for the similar categories of multiple packets transmission until the allocated time is expired. The static TXOP limits are defined for various categories of IMM traffics in the IEEE802.11e standard. Due to the variation of traffic load in WCN, the static TXOP limits are not sufficient enough to guarantee the quality of service (QoS) for IMM traffic flows. In order to address this issue, several existing works allocate the TXOP limits dynamically to ensure QoS for IMM traffics based on the current associated queue size and pre-setting threshold values. However, existing works do not take into account all the medium access control (MAC) overheads while estimating the current queue size which in turn is required for dynamic TXOP limits allocation. Hence, not considering MAC overhead appropriately results in inaccurate queue size estimation, thereby leading to inappropriate allocation of dynamic TXOP limits. In this article, an enhanced dynamic TXOP (EDTXOP) scheme is proposed that takes into account all the MAC overheads while estimating current queue size, thereby allocating appropriate dynamic TXOP limits within the pre-setting threshold values. In addition, the article presents an analytical estimation of the EDTXOP scheme to compute the dynamic TXOP limits for the current high priority traffic queues. Simulation results were carried out by varying traffic load in terms of packet size and packet arrival rate. The results show that the proposed EDTXOP scheme achieves the overall performance gains in the range of 4.41%-8.16%, 8.72%-11.15%, 14.43%-32% and 26.21%-50.85% for throughput, PDR, average ETE delay and average jitter, respectively when compared to the existing work. Hence, offering a better TXOP limit allocation solution than the rest.

    This systematic review was aimed to evaluate the effectiveness of technology-enhanced learning (TEL) used in medical teaching for undergraduate medical students. The objectives are to (a) identify various teaching modalities which are used to enhance TEL; (b) evaluate whether TEL is more effective than traditional learning (TL) in cognitive and affective learning domain outcome. The empirical studies were searched in the following databases: Google Scholar, MEDLINE, ERIC, ProQuest, Cochrane Library and Scopus. All papers published from 2008 to 2018 were included. From eligible studies, the study design, study field, study population, intervention methods, type of assessment and learning achievement were abstracted and summarized the information. The search results were independently reviewed by two authors. From a pool of 1384 articles, 43 eligible articles were identified, enrolling 7292 undergraduate medical students examining comparative study between TEL and traditional learning. The results showed that there was a high degree of heterogeneity seen amongst the included studies in terms of TEL modalities used. The majority of intervention studies favoured online resources, while the rest used various offline multimedia electronic devices, virtual simulations and blended modes. Overall findings showed promising data that TEL is better than TL with regards to knowledge gain and skill acquisition, as well as providing higher student satisfaction. In all, the findings present blended learning in a positive and promising light in time, particularly where systematic reviews on technology-enhanced learning in the field of the undergraduate medical programme have produced mixed result.REVIEW ARTICLEA Systematic Literature Review on Technology-Enhanced Learning in Medical EducationMay Honey Ohn1*, Bareth Ravindran2, Chan Zhi Wei3, Khin Maung Ohn4, Ng Pey Luen5Borneo Journal of Medical Sciences 14 (1) January, 2020: 3 – 171 Emergency Department, Sandwell & West Birmingham NHS Trust, United Kingdom2 Surgical Department, Hospital Tuanku Ja’afar Seremban, Kuala Lumpur, Malaysia3 Orthopaedics Department, Hospital Sungai Buloh, Kuala Lumpur, Malaysia4 Department of Surgery, Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia5 Radiology Department, Hospital Queen Elizabeth II, Sabah, Malaysia* Corresponding author’s email: mayhoney.ohn@gmail.com Received: 14 July 2019 Accepted: 5 November 2019Borneo Journal of Medical SciencesBJMSKeywords: blended learning, technology-enhanced learning, medical education, hybrid learning, undergraduate medical students

    According to the survey on various health centres, smart log-based multi access physical monitoring system determines the health conditions of humans and their associated problems present in their lifestyle. At present, deficiency in significant nutrients leads to deterioration of organs, which creates various health problems, particularly for infants, children, and adults. Due to the importance of a multi access physical monitoring system, children and adolescents' physical activities should be continuously monitored for eliminating difficulties in their life using a smart environment system. Nowadays, in real-time necessity on multi access physical monitoring systems, information requirements and the effective diagnosis of health condition is the challenging task in practice. In this research, wearable smart-log patch with Internet of Things (IoT) sensors has been designed and developed with multimedia technology. Further, the data computation in that smart-log patch has been analysed using edge computing on Bayesian deep learning network (EC-BDLN), which helps to infer and identify various physical data collected from the humans in an accurate manner to monitor their physical activities. Then, the efficiency of this wearable IoT system with multimedia technology is evaluated using experimental results and discussed in terms of accuracy, efficiency, mean residual error, delay, and less energy consumption. This state-of-the-art smart-log patch is considered as one of evolutionary research in health checking of multi access physical monitoring systems with multimedia technology.

    The increasing demand for network applications, such as teleconferencing, multimedia messaging and mobile TV, which have diverse requirements, has resulted in the introduction of Long Term Evolution (LTE) by the Third Generation Partnership Project (3GPP). LTE networks implement resource allocation algorithms to distribute radio resource to satisfy the bandwidth and delay requirements of users. However, the scheduling algorithm problem of distributing radio resources to users is not well defined in the LTE standard and thus considerably affects transmission order. Furthermore, the existing radio resource algorithm suffers from performance degradation under prioritised conditions because of the minimum data rate used to determine the transmission order. In this work, a novel downlink resource allocation algorithm that uses quality of service (QoS) requirements and channel conditions to address performance degradation is proposed. The new algorithm is formulated as an optimisation problem where network resources are allocated according to users' priority, whereas the scheduling algorithm decides on the basis of users' channel status to satisfy the demands of QoS. Simulation is used to evaluate the performance of the proposed algorithm, and results demonstrate that it performs better than do all other algorithms according to the measured metrics.

    Objective: This paper intended to review and analyse relevant published articles which have studied or applied multimedia as the educational medium for patients or their caregivers. The benefits were also recorded.

    Method: The search was performed across the databases EBSCO Host, Springer Link, Science Direct and PubMed for relevant studies. Only full-text articles using English as a language of publication were included. Eligible articles included any usage of multimedia intervention as health information delivery for patients or caregivers. No restriction for publication date was set to permit a wider capture.

    Result: Twenty articles met the inclusion criteria involving a total of 1,797 respondents. The studies have been conducted in various countries mostly in North American region followed by Europe. The focused disease for each study varied from asthma to cognitive impairment but most were on cancer. Problems in caregiving and depression were also reported. The overall data suggested that the multimedia-based education had generated modest improvement in self-efficacy, patient satisfaction, coping skills, and perceptions of social support. Cost benefits were also recorded. Additionally, patients’ behavioural changes were well maintained in parallel with the intervention programme.

    Conclusion: The evolution of multimedia as an educational medium is growing and its incorporation has benefited health education management especially in improving patients’ and their family’s psychosocial outcomes. However, due to still limited scientific evidence to support its value, further multimedia-based interventions should be developed out of the need to share information and knowledge among patients as well as caregivers.

    There are many problems in the routine badminton teaching; there are mainly three aspects in college teaching. One is that the hardware equipment related to badminton is not enough; the second is that the badminton teaching does not meet the educational goals; the third is that the participation of college students is not high, which is no longer suitable for the current practical teaching. In order to improve the teaching method of badminton and improve the students' special performance of badminton, this paper studies the teaching of badminton based on multimedia environment. 82 students majoring in badminton were randomly divided into two classes. The experimental class (n = 41) used multimedia badminton teaching, and the control class (n = 41) used traditional badminton teaching, which lasted for one semester. Before and after the experiment, the students' physical fitness and badminton performance were tested. And the two classes of students were to send questionnaires to investigate interest in learning badminton and teaching satisfaction. The results of standing long jump, 50 m, and 800 m of the experimental class were improved by 0.2 m, 1.13s, and 16.25s, respectively. This shows that the physical quality and badminton performance of the experimental class under the multimedia environment are better than those of the control class under the general teaching. In the experimental class, 16 students are very interested in learning badminton, and 22 students are very satisfied with the multimedia teaching method; in the control class, only 9 students are very interested in learning badminton, and only 13 students are very satisfied with the traditional teaching method, which shows that the interest and satisfaction of students in the experimental class under the multimedia environment are higher than those in the control class under the traditional teaching.

    INTRODUCTION: This study aimed to evaluate whether multimedia counselling (MC) using a touchscreen computer is as effective and time-efficient as conventional counselling (CC) in promoting correct metered-dose inhaler (MDI) technique, with or without the valved holding chamber (VHC).

    METHODS: Participants in the MDI-only and MDI-with-VHC groups were randomly assigned to the MC group or CC group. No blinding was imposed. Inhalation technique was assessed using checklists before and after counselling. Time spent on counselling was determined for all participants, while time taken to perfect the technique was determined only for participants who achieved perfect technique within one hour.

    RESULTS: The CC group had more elderly participants than the MC group, but the difference was not significant. MDI-only and MDI-with-VHC users showed significant improvement in their inhaler technique after multimedia (44.5 ± 28.0% and 44.1 ± 14.4%, respectively) and conventional counselling (36.8 ± 20.5% and 37.0 ± 14.6%, respectively). No significant difference in MDI technique enhancement was found between the two groups. Although no significant difference was found between the MC and CC groups with regard to the time spent on counselling and the time taken to perfect the technique, the average time spent on counselling was longer for MDI-only users. MDI-only users had 13.5 times the odds of failing to achieve perfect technique compared to MDI-with-VHC users (95% confidence interval 1.50-121.32, p = 0.020).

    CONCLUSION: MC and CC significantly improved MDI technique. Both methods showed comparable short-term effectiveness and time-efficiency in MDI technique education. VHC was beneficial, especially for MDI-users with hand-lung coordination problems.

    Camera attribution plays an important role in digital image forensics by providing the evidence and distinguishing characteristics of the origin of the digital image. It allows the forensic analyser to find the possible source camera which captured the image under investigation. However, in real-world applications, these approaches have faced many challenges due to the large set of multimedia data publicly available through photo sharing and social network sites, captured with uncontrolled conditions and undergone variety of hardware and software post-processing operations. Moreover, the legal system only accepts the forensic analysis of the digital image evidence if the applied camera attribution techniques are unbiased, reliable, nondestructive and widely accepted by the experts in the field. The aim of this paper is to investigate the evolutionary trend of image source camera attribution approaches from fundamental to practice, in particular, with the application of image processing and data mining techniques. Extracting implicit knowledge from images using intrinsic image artifacts for source camera attribution requires a structured image mining process. In this paper, we attempt to provide an introductory tutorial on the image processing pipeline, to determine the general classification of the features corresponding to different components for source camera attribution. The article also reviews techniques of the source camera attribution more comprehensively in the domain of the image forensics in conjunction with the presentation of classifying ongoing developments within the specified area. The classification of the existing source camera attribution approaches is presented based on the specific parameters, such as colour image processing pipeline, hardware- and software-related artifacts and the methods to extract such artifacts. The more recent source camera attribution approaches, which have not yet gained sufficient attention among image forensics researchers, are also critically analysed and further categorised into four different classes, namely, optical aberrations based, sensor camera fingerprints based, processing statistics based and processing regularities based, to present a classification. Furthermore, this paper aims to investigate the challenging problems, and the proposed strategies of such schemes based on the suggested taxonomy to plot an evolution of the source camera attribution approaches with respect to the subjective optimisation criteria over the last decade. The optimisation criteria were determined based on the strategies proposed to increase the detection accuracy, robustness and computational efficiency of source camera brand, model or device attribution.

    Under the framework of disciplinary knowledge integrating technology, the multimedia teaching application of music performance attracts a major opportunity for reflection and reconstruction. The purpose of this study is to explore the laws and experiences of music performance teachers' multimedia teaching applications under the framework of subject teaching knowledge integrating technology. Through the research to understand the classroom multimedia teaching application of music performance teachers, according to the research results, relevant strategies are put forward for the application of music performance teachers' classroom multimedia teaching, in order to effectively improve the classroom teaching effect of music performance teachers. This research mainly uses the classroom observation method and data statistical analysis method and takes 100 music video lessons of the National Educational Resources Public Service Platform as the survey object. A total of 100 teachers were observed and scored in the classroom through the compiled multimedia teaching observation table for music performance teachers, and then the data was analyzed to draw conclusions. The conclusions of this study are as follows: The multimedia application behaviors of the teachers of the excellent courses are different from those of the teachers of the daily classes. The two types of teachers have differences in the effectiveness of multimedia teaching application of music performance, and the scores of the practical application of information technology are uneven. The overall score of multimedia teaching applications of excellent course teachers is higher than that of daily course teachers, and the classroom teaching effect is better. In this regard, based on the observation and assessment of the effectiveness of multimedia teaching applications by two types of teachers, this paper puts forward some suggestions for music performance teachers to improve the effectiveness of multimedia teaching applications in classrooms from the aspect of teachers themselves and educational functions. It is hoped that it can provide some theoretical basis and practical materials for the personal and professional development of music performance teachers.

    Background: Colorectal cancer is a major public health problem. A way to decrease this cancer is through dietary behavioural changes. The aim of this study was to determine the effects of education on dietary behaviour based on the health belief model (HBM) using multimedia.

    Methods: In this clinical trial study, 98 participants were randomly allocated to an HBM group (n = 48) and a control group (n = 50). The HBM group received an audiovisual compact disc (CD) that contained information about nutritional behaviour of colorectal cancer (CRC) prevention based on HBM that lasted 45 min. Both groups completed questionnaires regarding demographic factors, knowledge and HBM constructs, and a three-day dietary recall at the beginning of the study, 1 week after, and 3 months after the education. The outcome of this study was measured by the amount of food servings consumed and dietary micronutrient intake.

    Results: At the baseline, there were no significant differences between groups regarding demographic factors. Findings showed that self-efficacy (P < 0.001), severity (P < 0.001), and benefits (P < 0.001) were perceived to be higher, and knowledge (P < 0.001) was increased in the HBM group compared to control group 3 months after education. There was a significant increase in fruit and vegetable (P < 0.001) and dairy (P = 0.001) intake and a significant decrease in red meat servings (P = 0.016) in the HBM group compared to the control group. Also, intake of vitamin D (P < 0.001), folate (P < 0.001), calcium (P = 0.008), and dietary fibre (P < 0.001) was increased in the HBM group compared to the control group 3 months after education.

    Conclusion: Education plans based on HBM and implemented through multimedia can change nutritional beliefs and behaviours for the prevention of colorectal cancer.

    Heuristic Evaluation (HE) is used as a basis in developing a new technique to evaluate usability or
    educational computer games known as Playability Heuristic Evaluation for Educational Computer Game (PHEG). PHEG was developed to identify usability problems that accommodate five heuristics, namely, interface, educational elements, content, playability and multimedia. In HE process, usability problems are rated based on severity score and this is followed by presentation of a mean value. The mean value is used to determine the level of usability problems; however, in some cases, this value may not accurate because it will ignore the most critical problems found in a specific part. In developing PHEG, a new quantitative approach was proposed in analyzing usability problems data. Numbers of sub-heuristics for each heuristic involved were taken into account in calculating percentage for each heuristic. Functions to calculate critical problems were also introduced. Evaluation for one educational game that was still in development process was conducted and the results showed that most of the critical problems were found in educational elements and content heuristics (57.14%), while the least usability problems were found in playability heuristic. In particular, the mean value in this analysis can be used as an indicator in identifying critical problems for educational computer games.
