Introduction: Smoking tobacco has been a longstanding issue worldwide, but the trend of smoking electronic cigarette (e-cigarette) is now on the rise. Many people have the view that smoking e-cigarette is safer and less harmful, and this is worrying. Adolescents and young adults are easily influenced by advertisements on e-cigarette. Thus, this study was conducted to determine the knowledge, attitude, and practice on e-cigarette among university students. Materials and methods: A cross-sectional study using self-administered questionnaire among 484 university students was carried out in a public university in Negeri Sembilan, Malaysia. Results: Respondents were 19 to 25 years old undergraduates, with the majority being female. In terms of smoking status, 32 (6.6%) of them were smokers, with only nine have ever tried e-cigarette, and only one being a regular user. Bivariate analysis showed knowledge, attitude and practices score on e-cigarette were correlated. Statistically significant associations were found between knowledge score and gender (p<0.001), while attitude and practice scores were associated with gender (p<0.001), household income (p = 0.013 and p = 0.001 respectively), as well as smoking status (p<0.001). Multivariate analysis revealed that being female and being a non-smoker were associated with higher attitude and practice scores. Conclusion: In conclusion, the awareness on e-cigarette needs to be improved among young adults and a more holistic intervention strategy should be implemented to prevent the rise of e-cigarette smoking.

Past studies show that non-ionizing radiation (NIR) exposure may affect living things. Thus, this kind of exposure needs to be monitored to provide sustainable public health. The proper measurement technique and the high gain antenna are required to obtain an optimum reading. The main purpose of this paper is to provide the performance analysis results of a circular patch (CP) antenna which operates up to 4 GHz. The antenna is designed and simulated using CST Studio Suite® software which has a simple circular radiation patch structure with half grounded plane with defected ground structure (DGS) design. The comparison between the performance of the proposed CP antenna characteristics and the simulation results were presented in terms of the radiation pattern, bandwidth, S-parameter, gain and efficiency for validation. Based on the actual measurement results, the CP antenna performance is acceptable since it successfully operates within the targeted frequency band (S-parameter: 0.89 GHz to 4 GHz) with the percentage of frequency bandwidth (FBW) that is equal to 127.2%. Besides, the highest gain of simulated and measured obtain are 2.099 dBi and 5.17 dBi respectively with the omnidirectional radiation patterns for both measurements. The developed antenna is suggested to be used in the ambient reading of frequency signals for NIR exposure measurement purpose. © Penerbit UMT.

The World Health Organization (WHO) has initially categorised COVID-19 infection as a Public Health Emergency of International Concern (PHEIC) in late January 2020 and later on declared the outbreak as a pandemic on March 11, 2020. On February 4, 2020 the first Malaysian positive COVID-19 patients was detected. It was estimated through a thorough decision tree technique, cumulatively 22,000 positive patients were expected to be infected nationwide. At the current rate of disease detection, screening yield and clinical capacity in Malaysia, the identification of the positive patients will have to be continuously done until middle of May 2020. In addition, a prediction with the forecasted testing capacity was also conducted. In contrast with the earlier estimation, massive testing causes the number of positive patients to be saturated earlier, by the end of April 2020. Based on the projection, 346, 307 cumulative tests will be conducted with 225,100 cumulative positive cases will be identified. Of the numbers, the cumulative number of patients in care would be 17,631 with 705 cumulative number of admission to intensive care unit and 353 cumulative patients required for ventilator. The cumulative death and cumulative discharge are expected to be 394 and 6008 respectively. Currently, it is challenging for Malaysia to flatten the epidemic curve due to the constraints of healthcare resources. These challenges potentially highlight the need for realistic strategies with regard to the country’s capacity.
