One of the variables leading to the global spread of COVID-19 cases is the weather, which includes temperature and air quality. In this study, an investigation of the association between precipitation and COVID-19 cases was conducted to provide useful information on the possibility of this climate factor (precipitation) on the progression of COVID-19 cases for an appropriate management strategy. Secondary COVID-19 and rainfall data obtained from the Ministry of Health and the Meteorological Department in Malaysia were used for the study. The collected data were subjected to Pearson correlation analysis. The results of this study showed that both rainy days and rainfall amount were insignificant to COVID-19 cases, indicating that rainfall amount was not associated with COVID-19 transmission in Terengganu, Malaysia. Thus, this discovery could be used to inform individual and COVID-19 supervisors and the government as it prepares for the new weather season.

There is a recognised need for a questionnaire playing a crucial role in eye care. Substantial research has been undertaken on the role of a questionnaire assessing the vision-related quality of life. However, the need for pictures to be embedded as a part of the questionnaires has not been recognised. This study investigated the verbal and visual interpretation of pictures about signs and symptoms of eye problems. 60 subjects aged 18 to 40 years old were recruited using convenient sampling in this cross-sectional study. Sixteen pictures representing three domains (physical signs, behavioural signs and visual- related activity) were included. The verbal interpretation was recorded for each picture. The visual interpretation was recorded as fixation count and duration using a heat map for three pictures representing each domain. All pictures (100%) under the physical signs category provided a high percentage (more than 80%) of correct verbal responses. A significant difference in the verbal responses was found between gender and two different levels of education for behavioural signs and visual-related activity pictures (p<0.05). Significantly longer fixation duration was found among respondents who provided incorrect verbal responses compared to correct verbal responses (p<0.05). A simple picture with direct information like ocular misalignment was more interpretable than a picture with abstract information like ‘glare’ and ‘writing up and downhill’. Both verbal and visual interpretations of the picture are closely correlated. Therefore, selecting pictures of eye care questionnaires for the general population should consider a minimum cognitive load to improve interpretability.

Inadequate knowledge, negative attitudes and unsafe practices while handling chemicals can contribute to incidents such as fires, accidents, injuries and fatalities at academic institutions and laboratories. The purpose of this study is to evaluate the knowledge, attitudes, and practices (KAP) of lab personnel towards chemical safety at an academic institution. A cross-sectional study was conducted among 123 laboratory personnel at Universiti Teknologi Mara (UiTM), Malaysia using purposive sampling. A self-administered questionnaire was distributed by email to collect data which was analysed using descriptive statistics, a Spearman Correlation Coefficient measures and a Chi-Squared test. In general, the respondents’ knowledge and attitudes towards chemical safety were high with median scores ranging between 79.2% and 88.9%, respectively. However, their practices were moderate, with a mean score of 74. 1%. There was a weak correlations between attitudes and the level of knowledge (rs = 0.38, p < 0.05) and practices (rs = 0.19, p < 0.05). There were significant associations between department, campus and training status (χ2 value, p < 0.05) with knowledge and practice levels. Although the overall scores were satisfactory, some aspects still need improvement, especially with regard to the Globally Harmonised System (GHS) of Classification and Labelling of Chemicals symbols, personal protective equipment (PPE) compliance and emergency response procedures. The practice of eating and drinking in laboratories by lab personnel is an issue that also requires attention.
在处理化学品时，不充分的知识、消极的态度和不安全的做法可能导致学术机构和实验室发生火灾、事故、伤害和死亡等事件。本研究的目的是评估某学术机构实验室人员对化学品安全的知识、态度和实践(KAP)。在马来西亚马拉理工大学123名实验室人员中进行了一项横断面研究，采用有目的的抽样方法。通过电子邮件分发自我管理问卷收集数据，并使用描述性统计、斯皮尔曼相关系数测量和卡方检验对数据进行分析。总体而言，受访者对化学品安全的知识和态度较高，得分中位数分别在79.2%和88.9%之间。然而，他们的实践是适度的，平均得分为74分。1%。态度与知识水平(rs = 0.38, p < 0.05)和实践(rs = 0.19, p < 0.05)呈弱相关。院系、校园、培训情况与知识水平、实践水平有显著相关(χ2值，p < 0.05)。虽然总体得分令人满意，但有些方面仍需改进，特别是在化学品符号分类和标签全球统一制度、个人防护装备合规和应急程序方面。实验室人员在实验室的饮食习惯也是一个需要注意的问题。

This study aims to explore participants’ insights and feelings towards exergame concepts to promote physical activity (PA). Specifically, aspects such as participants’ perceptions, knowledge and motivation towards exergame were analysed to investigate how exergame influences their engagement with PA and learning during online distance learning (ODL). This study adopted a qualitative research design. Both video recording (2 minutes/video) and drawings (i.e., discussed in part two) were utilised to explore the participants’ perceptions, knowledge, and motivation with exergame. Convenience sampling was utilised to gather participants who comprised of 45 first-year undergraduate physical and health education (PHE), biology and chemistry major students ages between 20-25 years (i.e., 13 males and 32 females, respectively). The Interpretive Phenomenological Analysis approach was referred to develop the procedures and instruments while Consider.ly software (Usertime Solutions GmbH) was used to analyse data from the videos and drawings. Additionally, the keywords and significant answers were also noted, clustered into main themes to ease understanding and superordinate themes related to this study. Findings indicate that: (i) Exergame concepts were effective in increasing both participants’ learning enjoyment and PA level, (ii) The addition of exergame was successful in promoting higher engagement between participants and educators, (iii) A lot of participants reported higher motivation to learn course contents and (iv) Perceived exergame as an opportunity to sharpen their thinking skills through challenges presented in exergame. Overall, the findings contribute to our understanding of how pedagogical strategies such as exergame can be adopted in and out of the classroom to promote desirable learning experiences and academic outcomes.

Wind energy is one of the five fuels that can support the reduction of greenhouse gases and climate change impact. Wind energy is one of the most promising renewable energy sources that can be exploited to succeed in 1/20 of the renewable energy mix in Malaysia. This study aimed to determine the value of GHG savings on wind energy potential based on Meteorological Aerodrome Report (METAR) data in Malaysia to establish a suitable wind farm in Kudat and Langkawi Island that can potentially generate electricity. The wind speed data were collected from the METAR report broadcasted hourly. Wind speed extrapolation was based on the selected wind turbine generator (WTG) with 950 kW and 60 kW capacity. The prospect of wind energy was analysed using the Weibull distribution to determine the parameter of shape (k) and scale (c) from the wind speed frequency distribution. Finally, the Annual Energy Production (AEP) and the GHG savings were estimated. Based on the study, the annual reduction of GHG emissions ranges from 150 to 1,300 tonnes of CO2 per year. The ten-year projection roughly estimates about 1,500 to 13,000 tonnes of CO2 per year. Implementing a low-carbon, cost-effective energy source would undoubtedly enhance Malaysia’s sustainable energy system, as proposed by the United Nations Sustainable Development Goals 7.

Accommodation of micro fluctuation has been the subject of many studies of ocular stability. Although there are three existing micro fluctuation reporting approaches encompassing the standard deviation approach, root means square approach and Fourier transform analysis, the direct comparison of these approaches is lacking. This study aims to descriptively compare the three reporting approaches using a single subject in the initial analysis. Measurement was done on the right eye using an open-field autorefractor (WAM-5500 Grand Seiko Co., Ltd., Japan) via the dynamic mode while looking at a distant target. The standard deviation (SD) approach recorded 0.1723 D accommodation micro fluctuation which was nearly identical to the root means square (RMS) approach of 0.1719 D. As for the Fourier transform (FT) approach, the variation was apparent in the low-frequency but not in the high-frequency component. Additional analysis showed the correlation coefficient between RMS and SD, between FT and SD and between FT and RMS was at 0.5776, 0.4745 and 0.4276, respectively (all P-values <0.01). In conclusion, the accommodation micro fluctuation can be aptly described through the root means square approach as it has fewer errors than the standard deviation approach and is less complicated than the Fourier transform approach.

The waters within the Royal Belum State Park are predominantly utilized for recreational activities and are the main source of water for indigenous tribes. Changes in population density, tourism and climate changes may impact water quality and the consequences to human and ecological health are of economic and social importance. An assessment of water quality in Temenggor Lake, Royal Belum State Park has been conducted at two sampling locations, namely visitor water activity areas (fishing, swimming, canoeing) and indigenous people water activity areas (dishes washing, laundry, open bathing) to determine and compare the microbiological and physicochemical parameters and to classify the safety of water usage based on the National Water Quality Standards classification for water activity use with body contact. Six locations were selected and analysed in-situ for temperature, dissolved oxygen, pH level and turbidity while total suspended solids, biochemical oxygen demand, ammoniacal-nitrogen, total coliform, enterococci and Escherichia coli were analysed in the laboratory. Results indicated that all physicochemical parameters (temperature, turbidity, total suspended solids, dissolved oxygen and biochemical oxygen demand) except pH and ammoniacal-nitrogen at the six samplings stations were within the acceptable range for water activity use. All stations were within class I to IIB for microbiological parameters in comparison to the National Water Quality Standards classification for Malaysia. This indicates that the waters were safe for water activity with body contact. Visitor water activity areas were safe and clean compared to indigenous people’s water activity areas and the differences were statistically significant. There is modest and visual evidence that the indigenous community may further reduce the water quality in their areas based on their daily sanitation practises of dishwashing and open defecation on land. Hence, the responsibility falls on the authorities to provide a good sewage management system and treated water at the indigenous people’s settlement to protect the lake water quality from deteriorating in the future and contributing to the adverse health effects of its users.

Food waste is the second-highest source of solid waste in Malaysia. It accounts for about 32% of the total volume of waste generated in the country. Western food restaurants and Indian Muslim (also known as Mamak) restaurants in Northern Region, Malaysia are fast-growing food establishments and have become common among Malaysians of different races. Thus, this study aimed to identify the waste generation, carbon footprint and water footprint during the daily operation of these two types of food establishment. The waste from the food establishment was classified and measured into three categories: Preparation loss (PREP), serving loss (SERV) and customers’ plate loss (PLATE). The Material Flow Analysis (MFA) was used to exhibit the amounts of food waste generated and the factors that most significantly contributed to the amount of food waste during daily operations. The findings of this study presented that PLATE waste contributed to most of the food waste with 62.9% (Western) and 54.9% (Indian Muslim), compared to PREP losses generated which were 37.1% (Western) and 45.1% (Indian Muslim). The weekly average electricity consumption was 17.3 kWh (Western) and 267.8 kWh (Indian Muslim). Besides, the total weekly carbon footprint was 17.6 kgCO2e (Western) and 29.24 kgCO2e (Indian Muslim). Meanwhile, the total average water consumptions were 21.82 m3 (Western) and 38.2 m3 (Indian Muslim) and the total carbon footprint emission per week was 7.5 kgCO2e (Western) and 13.19 kgCO2e (Indian Muslim). The management of the food establishment may be able to recognise the areas for improvement in reducing food waste generation and carbon footprint from their daily operations.

It accounts for about 32% of the total volume of waste generated in the country. Western food restaurants and Indian Muslim (also known as Mamak) restaurants in Northern Region, Malaysia are fast-growing food establishments and have become common among Malaysians of different races. Thus, this study aimed to identify the waste generation, carbon footprint and water footprint during the daily operation of these two types of food establishment. The waste from the food establishment was classified and measured into three categories: Preparation loss (PREP), serving loss (SERV) and customers’ plate loss (PLATE). The Material Flow Analysis (MFA) was used to exhibit the amounts of food waste generated and the factors that most significantly contributed to the amount of food waste during daily operations. The findings of this study presented that PLATE waste contributed to most of the food waste with 62.9% (Western) and 54.9% (Indian Muslim), compared to PREP losses generated which were 37.1% (Western) and 45.1% (Indian Muslim).

A global pandemic known as COVID-19 now threatens public health systems worldwide. The COVID-19 virus is spread by many sources, including environmental factors. Infectious diseases are transmitted and are resistant to certain environmental factors, including temperature, humidity, wind speed and population density. Through preferred reporting items for systematic reviews and meta-analyses, a study on the effects of environmental factors on the spread of COVID-19 cases in Asia was carried out to provide evidence-based knowledge and serve as a basis for health care and preventative guidelines (PRISMA). Search databases like Web of Science (WoS), Scopus and PubMed were used to find the data. A total of 52 full-text papers, 1,780 abstracts and 16 systematic review articles were examined. The results indicate a clear correlation between environmental factors, population density and the occurrence of COVID-19. These findings suggest that environmental factors may play a role in the distribution of COVID-19 in Asia.
被称为COVID-19的全球大流行现在威胁着世界各地的公共卫生系统。COVID-19病毒有多种传播途径，包括环境因素。传染病具有传染性，对温度、湿度、风速和人口密度等环境因素具有抵抗力。通过系统评价和荟萃分析的首选报告项目，开展了环境因素对亚洲COVID-19病例传播影响的研究，以提供循证知识，并为卫生保健和预防指南(PRISMA)提供依据。使用Web of Science (WoS)、Scopus和PubMed等搜索数据库查找数据。全文论文52篇，摘要1780篇，系统综述文章16篇。结果表明，环境因素、人口密度与COVID-19的发生有明显的相关性。这些发现表明，环境因素可能在COVID-19在亚洲的分布中发挥作用。
