BACKGROUND: There have been some concerns related to manual handling of large items in industry. Manual handling operations of large sheet metal may expose workers to risks related to efficiency as well as occupational safety and health. Large sheet metals are difficult to move and burdensome to lift/transfer, and handling the sharp sheet edges may result in contact stress and/or cut injuries on the workers. METHODS: Through observation, interview, and immersive simulation activities, a few problems related to current handling of sheet metals were identified. A sheet metal trolley-lifter was then designed and fabricated to address these issues. A pilot study on the use of the developed trolley-lifter for handling sheet metals was conducted to compare between the new and traditional handling methods. RESULTS: The pilot study of the trolley-lifter showed promising results in terms of improving the cycle time, manpower utilization, and working postures compared with the traditional handling method. CONCLUSION: The trolley-lifter offers an alternative solution to automation and a mechanized assistive device by providing a simple mechanism to assist the handling of sheet metals effectively and safely.

Introduction: This study aimed to determine the risk factors of CHD among the Malaysian adult population. Methods: Using a cross- sectional observational study design, this study involved 365 adult patients aged between 30-64 years, attending clinics from eight government hospitals and four health clinics in Terengganu, Pahang, Selangor, Putrajaya, Penang, Kedah, Johor and Sabah from February 2018 until September 2020. Sociodemographic characteristics, clinical and dietary data, physical activity and stress level were recorded using a structured questionnaire. Multiple logistic regression was used to analyse CHD risk factors. Results: The overall response rate was 99.2%. The adjusted odds ratio of CHD was greater for age (AOR; [%95 CI]) (1.043;[ 1.009,1.078]); waist circumference (1.033;[1.009, 1.057]); total fat intake (1.035;[1.021, 1.050]); full cream dairy products intake (1.004;[1.001, 1.008]); smokers vs non-smokers (4.691;[2.399, 9.176]); individual with family history of CHD vs without family history (2.705;[ 1.496, 4.891]); married vs single (0.434;[ 0.217,0.867]); and lower for HDL cholesterol (0.185;[0.052, 0.662]); Chinese vs Malays (10.619;[ 2.255, 49.995]); and third lowest income (0.197;[ 0.073, 0.532]) and forth lowest income (0.167;[ 0.056, 0.499]) vs lowest income. Conclusion: Age, race, income, smoking and marital status, family history of CHD, waist circumference, HDL cholesterol, total fat intake, full cream dairy products intake were significantly associated with CHD among this population. This finding is particularly important to the primary health carers to identify at-risk CHD individuals thus appropriate intervention could be provided.

Aims: Coral diseases have emerged over the last several decades, causing a loss of live coral cover in the Caribbean and Indo-Pacific reefs. Hence, microbiological and disease cultural techniques are commonly used to investigate their causative microbial agents. This is the first study to identify the potential of pathogenic Vibrio spp. isolated from apparently white syndrome (WS) coral disease in Tioman Island Marine Park using biochemical and molecular techniques. Methodology and results: The Vibrio colonies were isolated from 108 samples of WS infected corals (Acropora cytherea and Montipora aequituberculata) including seawater, sediment and algae found adjacent to infected coral colonies. A total of one hundred representative Vibrio isolates were characterized and most of them (n=50) were identified as V. vulnificus, V. alginolyticus and Photobacterium damselae following biochemical analysis. The molecular analysis revealed six Vibrio spp. (V. coralliilyticus, V. hepatarius, V. brasiliensis, V. tubiashi, V. campbellii, V. ishigakensis) and one Photobacterium rosenbergii. Vibrio coralliilyticus isolated from all infected coral samples may be highly responsible for the sign of WS disease. Conclusion, significance and impact of study The findings of this study provide baseline data and information on potential coral pathogens identified in the coastal waters of Tioman Island. Etiological disease study is suggested to validate their severity and virulence factors in the future.
