Drivers’ posture is one of the factors that can contribute to driving discomfort. Subjective evaluation is needed in
determining the driving discomfort problem. The purpose of this study is to examine the reliability of different
driving postures that may lead to drivers’ discomfort. A total of thirty-four healthy Malaysian drivers were involved
in this study. Respondents were required to sit on the driver’s seat with the required adjustments of three different
postures and fill-in the given subjective evaluation form. The same procedure was repeated for each respondent
after three days for purpose of conducting test retest evaluation. The reliability statistical analysis result shows the
study was reliable and valid with a Cronbach’s alpha coefficient equal to 0.827. The comparison means that ANOVA
analysis also shows significance difference between these three groups of postures for all measured parameters. In
conclusion, the result from this study shows the subjective evaluation conducted is reliable and can be used for
drivers’ posture discomfort study.

Road transport is the movement of passengers or goods on the road. To date, issues concerning the safety of students and school institutions have continued to attract public attention. The recent spate of incidents insideand outside the school compoundhas brought the issue of children safety into our attention. These include the escalating number of road casualties. This study was conducted to observe road hazard outside the school compound and analyse the safety risksfaced by school children by using the risk matrix. The risks are calculated to include likelihood and severity of hazard as identified in the Guideline of HIRARC 2008. The area selected was the East Coast state of Peninsular Malaysia, with over 111 schools randomly selected in Kelantan. Results werethen analysed and six highlighted hazards were discussed. The results show that the main road posed the highest risk due to speeding vehicles. These vehicles failed to slow down when approaching the school area. The school administrationmustenhance the safety of the staff, students, and public while in the school area. In conclusion, road safety awareness must be instilledamong teachers, students, parents and road users alike.

This study investigates indoor environmental factors in several offices from one of the university at Malaysia's East Coast, focusing on enhancing occupational health and well-being among university staff by examining lighting quality and thermal comfort. Monitoring sampling were done based on hazard reports logged and data from three main offices or location were collected in this study. Utilizing Extech HD450 Heavy Duty Data Logging Light Meter to measure illuminance, the study found that most sampled points fell below the Occupational Safety and Health Guidelines' recommended range of 300-500 lux, indicating insufficient lighting that can cause visual discomfort and reduce productivity. Thermal comfort assessments, conducted with EVM-7 Indoor Air Quality 3M QUEST and AirPro Solution Models AP500, revealed acceptable temperature and humidity levels but often inadequate air velocity, particularly in the Science Officer's Office, leading to poor air circulation and potential health issues. The study highlights the necessity of improving lighting solutions by installing additional fixtures or upgrading existing ones for sufficient and evenly distributed illumination and enhancing ventilation systems to ensure adequate air movement. Addressing these deficiencies is crucial for creating a conducive working environment, promoting employee satisfaction and productivity. This research focuses solely on monitoring and analyzing the collected data. No qualitative evaluation has been conducted as part of this study. This research advocates for a holistic approach to Indoor Environmental Quality (IEQ), involving regular assessment and targeted interventions to enhance the overall quality of university office environments, ultimately fostering a healthier and more productive workplace.
