    Stone Mastic Asphalt (SMA) is one type of asphalt mixture which is highly dependent on the method
    of compaction as compared to conventional Hot Mix Asphalt (HMA) mixture. A suitable laboratory compaction method which can closely simulate field compaction is evidently needed as future trend
    in asphalt pavement industry all over the world is gradually changing over to the SMA due to its excellent performance characteristics. This study was conducted to evaluate the SMA slab mixtures compacted using a newly developed Turamesin roller compactor, designed to cater for laboratory compaction in field simulation conditions. As the newly developed compaction device, there is a need for evaluating the compacted slab dimensions (which include length, width, and thickness), analyzing the consistency of the measured parameters to verify the homogeneity of the compacted slabs and determining the reliability of Turamesin. A total of 15 slabs from three different types of asphalt mixtures were compacted, measured, and analyzed for their consistencies in terms of length, width, and thickness. Based on study the conducted, the compacted slabs were found to have problems in terms of the improperly compacted section of about 30 mm length at both ends of the slabs and the differences in the thickness between left- and right-side of the slab which were due to unequal load distribution from the roller compactor. The results obtained from this study have led to the development of Turamesin as an improved laboratory compaction device.

    INTRODUCTION: Doctors play an important role to assess and manage pain. Failing to do so properly, pain will affect the quality of life and increase the length of hospital stay for patients. In Queen Elizabeth Hospital (QEH), Kota Kinabalu, Sabah, pain assessment and management programs have been conducted on a regular basis. However, there has been no studies to assess the effectiveness of these programs.

    METHODOLOGY: This is a cross-sectional study to assess the knowledge and attitude on pain assessment and management among medical officers at QEH. A universal sampling technique was used, to represent medical officers from major clinical departments. The Knowledge and Attitudes Survey Regarding Pain (KASRP) questionnaire was used for this study.

    RESULTS: A total of 278 questionnaires were distributed to medical officers. The study sample consisted of 125 females (44.9%), and 153 males (55.1%). The age group of the participants ranged from 25 to 41 years old. A 116 respondents scored less than 60% on the knowledge of pain (41.7%). These findings show there was a deficit in their knowledge and attitude about pain. There was also a difference of scores between genders, where the male doctors performed better than the female doctors. There was a difference between scores among doctors from different departments. The highest mean score was from the department of Anaesthesia (80.2%). There was also a difference regarding pain knowledge based on the years of working as a doctor, where the highest passing rate was from doctors working for more than five years.

    CONCLUSION: This study demonstrated that there is a lack of knowledge and attitude on pain assessment and management among QEH medical officers who responded to this study. This will support the plan on a more aggressive and continuous education programme to improve pain assessment and management among doctors in QEH.

    INTRODUCTION: Medical practice involves routinely making critical decisions regarding patient care and management. Many factors influence the decision-making process, and self-confidence has been found to be an important factor in effective decision-making. With the proper transfer of knowledge during their undergraduate studies, selfconfidence levels can be improved. The purpose of this study was to evaluate the use of High Fidelity Simulation as a component of medical education to improve the confidence levels of medical undergraduates during emergencies.

    METHODOLOGY: Study participants included a total of 60 final year medical undergraduates during their rotation in Medical Senior Posting. They participated in a simulation exercise using a high fidelity simulator, and their confidence level measured using a self-administered questionnaire.

    RESULTS: The results found that the confidence levels of 'Assessment of an Emergency Patient', 'Diagnosing Arrhythmias', 'Emergency Airway Management', 'Performing Cardio-pulmonary Resuscitation', 'Using the Defibrillator' and 'Using Emergency Drugs' showed a statistically significant increase in confidence levels after the simulation exercise. The mean confidence levels also rose from 2.85 to 3.83 (p<0.05).

    CONCLUSION: We recommend further use of High Fidelity Simulation in medical education to improve the confidence levels of medical undergraduates.

    INTRODUCTION: Patients with chronic pain have been one of the most difficult patients to manage during the COVID-19 pandemic. As pain physicians navigate through this pandemic in order to maintain contact with their patients, telemedicine emerged as a very useful tool. It helped patients to access care despite being in distant areas, or during the lockdown period. The objective of this research is to assess the perception of chronic pain patients who received telemedicine therapy. Self-efficacy and coping level of pain among these chronic pain patients were also assessed.

    MATERIALS AND METHODS: This is a cross-sectional study involving patients who are under follow-up at the Chronic Pain Clinic, Hospital Pulau Pinang for more than a year and received telemedicine during this pandemic. Participants had to fill out a self-administered questionnaire. Once respondents completed the questionnaires, the answered questionnaires were collected for analysis.

    RESULTS: A total of 154 patients between 22 and 88 years old were included in this study. Most of the participants had a history of pain for more than 3 years (44.2%). The majority of our patients are still working (55.8%). From the patients who were working, 7.8% of them lost their jobs during the pandemic. 31.2% of patients reported that the pain condition had worsened while the rest did not experience any difference in their pain condition. More than half (59%) of the patients' reported telemedicine was beneficial for their pain management, while only 41% felt that their telemedicine was helpless for their pain management during the pandemic.

    CONCLUSION: Telemedicine is beneficial for patients with chronic pain. Telemedicine can be used poste-pandemic and may produce a good outcome with patients.

    Geopolymer concrete has the potential to replace ordinary Portland cement which can reduce carbon dioxide emission to the environment. The addition of different amounts of steel fibers, as well as different types of end-shape fibers, could alter the performance of geopolymer concrete. The source of aluminosilicate (fly ash) used in the production of geopolymer concrete may lead to a different result. This study focuses on the comparison between Malaysian fly ash geopolymer concrete with the addition of hooked steel fibers and geopolymer concrete with the addition of straight-end steel fibers to the physical and mechanical properties. Malaysian fly ash was first characterized by X-ray fluorescence (XRF) to identify the chemical composition. The sample of steel fiber reinforced geopolymer concrete was produced by mixing fly ash, alkali activators, aggregates, and specific amounts of hook or straight steel fibers. The steel fibers addition for both types of fibers are 0%, 0.5%, 1.0%, 1.5%, and 2.0% by volume percentage. The samples were cured at room temperature. The physical properties (slump, density, and water absorption) of reinforced geopolymer concrete were studied. Meanwhile, a mechanical performance which is compressive, as well as the flexural strength was studied. The results show that the pattern in physical properties of geopolymer concrete for both types of fibers addition is almost similar where the slump is decreased with density and water absorption is increased with the increasing amount of fibers addition. However, the addition of hook steel fiber to the geopolymer concrete produced a lower slump than the addition of straight steel fibers. Meanwhile, the addition of hook steel fiber to the geopolymer concrete shows a higher density and water absorption compared to the sample with the addition of straight steel fibers. However, the difference is not significant. Besides, samples with the addition of hook steel fibers give better performance for compressive and flexural strength compared to the samples with the addition of straight steel fibers where the highest is at 1.0% of fibers addition.

    Amniotic membrane has the potential to be used as scaffold in various tissue engineering applications. However, increasing its biostability at the same time maintaining its biocompatibility is important to enhance its usage as a scaffold. This studied characteristics genipin-crosslinked amniotic membrane as a bioscaffold. Redundant human amniotic membranes (HAM) divided into native (nAM), decellularized (dAM) and genipin-crosslinked (clAM) groups. The dAM and clAM group were decellularized using thermolysin (TL) and sodium hydroxide (NaOH) solution. Next, clAM group was crosslinked with 0.5% and 1.0% (w/v) genipin. The HAM was then studied for in vitro degradation, percentage of swelling, optical clarity, ultrastructure and mechanical strength. Meanwhile, fibroblasts isolated from nasal turbinates were then seeded onto nAM, dAM and clAM for biocompatibility studies. clAM had the slowest degradation rate and were still morphologically intact after 30 days of incubation in 0.01% collagenase type 1 solution. The dAM had a significantly highest percentage of swelling than other groups (p
