Malaysian Journal of Public Health Medicine.2020;20(Special 1):1-5. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.673

Chemicals usage has been reported as the cause of accidents in a laboratory. Those accidents have caused many injuries, even fatality in many sectors, one of which happened in the University Teaching Laboratory. Accidents usually happen because of unsafe behavior, while unsafe behavior is caused by bad safety perceptions. This paper investigates the correlation of perceptions and behavior in University Teaching Laboratory. The result measured by regression analysis to find out the relationship between two variables showed that there is a strong relationship between perceptions and behavior. Therefore, safe behavior can be created through creating good perception.

Malaysian Journal of Public Health Medicine.2020;20(Special 1):6-13. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.662

Learning is important for the development of children with special needs. Slow learners, which are included in the special-needs category suffer from extreme timidity thus making them unable to actively involved in learning sessions. It is important for them to actively involve in the learning activities as it affects their academic achievement. This study involves two phases of activities which are; Phase 1, identification specification through literature review and expert interview, and Phase 2, model development. From the specification identification phase, suitable elements and components are identified, gathered, analysed and organised to prepare a comprehensive model. Therefore, a robotic-based model for slow learners’ learning is proposed. The model consists of the elements and the components that emphasize interactive student-centred learning. The model is derived from Care-Receiving Robot, Social Development Theory and Triple-D Model which consists of the teacher (More Knowledgable Other), the student, the robot (Care-Receiving Robot), learning by teaching to invoke student-centred learning, and evaluation (Triple-D Model).

Malaysian Journal of Public Health Medicine.2020;20(Special 1):14-22. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.663

Reported fatal accidents in Malaysia construction industry contributed the highest number among other industries since 2009 until 2018. These statistics are alarming and elucidate the need to conduct scientific research to find the solution to solve the problem. Safety and health issues remain critical to the construction industry due to its working environment and the complexity of working practices. To prevent an accident, hazard identification is essential to construction safety management because unidentified hazards present the most unmanageable risks. Therefore, this research is conducted to help in reducing occupational accidents in the construction industry, and it can be considered worthy. This study aims to understand the triggering events, and their factors leading to fatal accidents are of significant input. The obtained data were analyzed using a statistical analysis program. Data collections of 139 numbers of respondents have been conducted in six different construction sites in east Malaysia. The result showed that there is a correlation between worker's perspective on safety management in the construction site and accident that can lead to a more fatality rate compared to other sectors. The corresponding recommendations are ultimately put forward as fatal accident prevention in construction activities. The patterns found in this paper can contribute valuable direction for formulating accident prevention strategies. In future research, reporting of an accident and near misses are essential to be further explored.

Nature of psychosocial risk as to the unseen hazards in the working population, potentially exposing the workers towards the adverse effect of mental health. Compromising the well- being of mental health could lead to deterioration of work performance. The objective of this study is to analyze the constructed measure of psychosocial risk factors and work performance of manufacturing workers using statistical analysis. Then, the constructed measure is used to find the correlations between the two factors. A set of the questionnaire is administered to 258 manufacturing workers. The questionnaires were adapted and adopted from Copenhagen Psychosocial Questionnaire (COPSOQ III), NIOSH Generic Job Stress Questionnaire, and Individual Work Performance Questionnaire (IWPQ 1.0) and the instrument were found to be reliable (Cronbach Alpha value = 0.7 ). After conducting Exploratory Factor Analysis by using Principal Component Analysis, the construct validity to conduct data collection in the manufacturing industry is tested. Using eight factors understudy that already extracted using factor analysis, it is found that there are significant psychosocial risk factors present in the manufacturing industry. As for the association between psychosocial and work performance, it is found that there is a significant association between psychosocial risk factors and work performance. This study is essential to explore the presence of psychosocial risk factors that underlies in the manufacturing industry, which might affect worker performance and well-being. For future research, it is recommended so that this study can be replicated to other manufacturing industry or different types of industries to see the robustness of the developed instruments. At the same time, the issue of psychosocial risk factors and workers' performance also can be identified, and the mitigation can be planned.

R Zirwatul Aida R Ibrahim ; Raja Zirwatul &lsquo ; Adawiah Raja Ibrahim

Malaysian Journal of Public Health Medicine.2020;20(Special 1):30-37. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.665

This study investigates the mall's Indoor Air Quality (IAQ) to compare changes in levels of Volatile Organic Compounds (VOCs) concentration in the morning and evening. It also explores the sources of emission released that could be related to occupants' health status (dizziness, headaches, flu, running nose, nose stuffy, nose irritation, eye irritation, watery eye, and eye reddening). A questionnaire survey approach was used to collect quantitative data involving 32 workers from malls in Malacca, Malaysia. This study established models to measure changes in VOCs level in two different sessions for a given area. Also, predictors related to the work context (human performance and condition) were found to be significantly related to occupants' symptoms. Two significant values identified the changes in VOCs concentration for morning and evening sessions in the lobby, bakery, eye ware shop, mobile centers, and supermarket. No evidence supports the exposure towards the personal individual in the present findings. This study contributes to the literature on levels of VOCs in the shopping mall as well as the emission sources. It also suggests that more comprehensive monitoring can be achieved, particularly in the context of Malaysia.

Malaysian Journal of Public Health Medicine.2020;20(Special 1):38-44. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.666

A coal mining industry typically applies a 24-hours working time, which enforces some workers to stay conscious during night shift, opposing human body's biological clock. This study aims to analyse the level of fatigue experienced by high dump truck operators (HD operators) in a coal mining site in East Kalimantan, Indonesia. This study utilizes primary data which obtained from distributing Industrial Fatigue Research Committee (IFRC) survey to all HD operators and secondary data (for Fatigue Likelihood Scoring -FLS) which consists of HD operators’ working schedule that currently applied in the company. Results obtained is analyzed using Fatigue Risk Management System (FRMS) framework which combines FLS classification and Dawson-McCulloch’s model of fatigue risk trajectory. This study reveals that based on IFRC survey, HD operators experienced low/mild fatigue due to insignificant influence of fatigue-related factors contained in the survey. However, consideration for improvement is in need since the resultof fatigue for night shift operators is close to moderate level. In addition, based on FLS, the level of fatigue indicates that HD operators experienced excessive working hours, in which in FRMS graph classified as fatigue-related errors. Thus, this studyproposes several strategies as the hazard control mechanism: (1) providing optimum resting time, (2) equipping operators with audio music that lead to positive energy and increasing work focus, and (3) adding afternoon shift to balance the working hours.

Malaysian Journal of Public Health Medicine.2020;20(Special 1):60-63. doi:https://doi.org/10.37268/mjphm/vol.20/no.Special1/art.705

Nurse is a profession that has a quite high workload. It can be seen from how often they should encounter situations which compel them to undergo precisely right decision in saving patients’ lives. Various environmental conditions increase the frustration rate of the nurses, such as noise of the crowds and medical equipment, as well as smell of medicines and wounds at once. Moreover, demands from the patients’ family make it even tougher for them. Therefore, this study aims to measure the mental workload of the nurses at Intensive Care Unit (ICU) and emergency unit (IGD) in the Hospital ZA based on their years of service. The study was conducted using the method of NASA-TLX (National Aeronautics and Space Administration – Task Load Index). It measured the workload in six dimensions: Mental Demand (MD), Physical Demand (PD), Temporal Demand (TD), Own Performance (P), Effort (EF), and Frustration Rate (FR). The results of the study show that the average value of the nurses’ workload at ICU and IGD is in the category very high (respectively 80 and 83) for the nurses with 0-3 years of service, and the most contributing factor for both the primary groups is the effort (EF).
