Abstract

In the new era of world industrialization, ergonomics plays an important role to improve occupational safety and health, and productivity in most industries including an aerospace industry. However, the manufacturing industry in Malaysia does not put any priority on ergonomics awareness, for an example, by not selecting a suitable height of workstation with operators’ anthropometry. Ergonomics so far has litle impact in Malaysia as majority of the Malaysian managers had believed that the ergonomics is not considered to be associated with performance. In a recent study on ergonomics awareness in Malaysian manufacturing industries by Mustafa et al., (2009), the researchers discovered that the main factors for the lack of ergonomics awareness were the lack of information/education/training and no pressure from the top management to initiate the ergonomics programmes. As a consequence, operators are exposed to various ergonomic risk factors and prone to have ergonomic injuries. The objective of this study was to reduce the maximum effort level of lumbar muscles of operators by changing the height of workstation using suitable anthropometry among operators. 

This study has conducted two analyses; analysis for quantify maximum effort level of lumbar muscle, and analysis for identify comfort level of working posture The surface Electromyography (sEMG) and Rapid Upper Limb Assessment (RULA) method from Computer-Aided Three-Dimensional Interactive Application (CATIA) software are used to evaluate maximum effort level of lumbar muscle, and comfort level of working posture respectively. Results for maximum effort level of lumbar muscle and comfort level of working posture found that by changing the anthropometry with suitable height of workstation has diminished the physiological stress such as work load in lumbar fascia muscle as well as extreme working posture. 

The study concluded that anthropometry of operators associated with the height of workstation was influenced the maximum effort level of lumbar muscle and comfort level of working posture when operators performing their jobs. The appropriate selection of workstation’s height can contribute significantly to improve physiological performance of the operators.

Abstract

In aerospace industries, many working tasks require their workers to perform the works in push-pull activities. The workers need to push or pull the mould tool in a long distance in to a workplace. Performing these activities continuously throughout the working hours, may lead to an early initiation of musculoskeletal disorders (MSDs) symptoms as workers developed muscle fatigue particularly concerning the hand muscles. Grip strength is the force applied by the hand to pull objects and is a part of hand strength. Repetitive usage of hands will create an imbalance between closing and opening (antagonist) muscles, which can lead to problem such as carpal tunnel syndrome (CTS). 

The primary purpose of this study was to develop a regression model based on psychophysical and biomechanical factors that contributes to fatigue, in which the models can predict the relationship between the input parameters and output responses. The methodology used for this study focused on three types of data collection which were questionnaire and observation which conducted as the preliminary study to prove the problems that have been stated and experimental was conducted by using surface Electromyography (sEMG) and Tekscan system to evaluate the muscle fatigue and hand grip pressure force of the Lay-up workers who were performing push activity. 

This study investigates the hand grip pressure force for the right hand and left hand within 5 minutes and 10 minutes of time exposure while workers pushing the mould tool, and study the relationship between time exposure with hand grip pressure force and muscle fatigue. The input parameters evaluated were time exposure, hand side and body mass index (BMI); while the output responses are muscle fatigue (voltage), hand grip pressure force (left hand), and hand grip pressure force (right hand). Two polynomial equations were successfully developed and validated. The modelling validation runs were within 90% prediction interval of the developed models and their residual errors compared to the predicted values were less than 10%. The significant parameters that influenced the output responses were also identified. Muscle fatigue was influenced by time exposure, hand side, BMI, and interaction between hand side and BMI; while hand grip pressure force was influenced by time exposure, hand side, BMI, interaction between time exposure and hand side, interaction between time exposure and BMI, and interaction between hand side and BMI.

Abstract

Improper riding behavior is one of the leading contributors for road crashes. Not wearing helmet, speeding, riding during fatigue and sleepy, and improper procedure during merging in traffic are among the poor behaviors of motorcyclists. For this study, improper merging behavior is the focus. 

The objectives of the study are: (i) to evaluate motorcyclists head check behavior during merging in traffic; (ii) to evaluate the differences of motorcyclists head check behavior during merging in traffic with different environments – highway and town (with and without U-turn situations). A naturalistic observation study was done where 1091 motorcyclists were observed at eight locations (scenarios) – four of highway road environment, two of town with U-turn environment, and two of town without U-turn environment. The dependent variable is the percentage of head checks. If a motorcyclist performs head check towards the target zone (the area in which the potential hazard may merge – at the entering road) while in the launch zone (the area where a motorcyclist should turn his or her head to the target zone – on the leaving road), he or she was scored one, else he or she was scored zero. 

It was found that, in overall, the percentage of motorcyclists who performed the head check (39.9%) is less than those who did not performed the head check (60.1%) – p ≤ 0.001. In term of the type of the road environment, similar results were found for the merging with highway environment (29.4% performed head check) and town without U-turn environment (31.4% performed head check). In contrast, for the merging with town with U-turn environment, the opposite result was found (75.7% performed head check). These differences were significant with p ≤ 0.001. This study provides prevalence information about Malaysian motorcyclists’ behavior in general and, more particularly, their behavior on the head check during merging in traffic. The findings shall recommend for an improvement to the current Malaysia riding/driving education system and road users awareness program in which may decrease the road crashes.

Abstract

Driver distraction is becoming a growing concern in Malaysia since in vehicle electronic devices are becoming more common in cars. Among the technologies being installed in cars is Heads Up Display (HUD). HUDs are meant to help drivers to focus their attention towards the forward roadway while driving by providing a simplistic display of speed and car navigation while driving. In this study, a Kansei Engineering approach is used to translate the usability requirements for HUD interfaces. A new HUD interface design was developed based on important features such as digital speed indicator, speed limit sign, as well as the indicator for the next turning.

Abstract

Numerous studies are conducted to study the ergonomics risk factors among schoolchildren and office workers. No study had been conducted yet on the ergonomic risk factors for university students in Malaysia. The aim of this study was to investigate the risk factors associated with musculoskeletal discomfort among the university students. This is a cross-sectional study. The respondents were selected using a simple random sampling method. Musculoskeletal discomfort (MSD) was recorded using MSD Questionnaire. Rapid Upper Limb Assessment (RULA) was used to assess awkward posture of student’s torso namely bending forward movement, leaning, sitting and twisting. Rapid Office Strain Assessment (ROSA) was used to quantify risk associated with the work station of the students with computer related activities. Anthropometric measurement which consist of weight and sitting measurement of a respondents using anthropometry set to measure the possible mismatch between the body dimension of the students and furniture dimension. Four possible mismatch that measured were popliteal height and seat height; buttock-popliteal length and seat depth; knee height and table clearance; and elbow rest height and table height. Results showed that the prevalence of discomfort among the students was 76.7%. Results of Chi Square test showed that there was no association between discomfort and demographic factors for gender, age, BMI and ethnicity. There was no association between discomfort and ergonomic factors including ROSA (χ² = 2.635, p-value = 0.105), RULA (χ² = 4.634, p-value = 0.099), MSD complain (χ² = 0.032, p-value = 0.857) and mismatch (χ² = 0.332 p-value = 0.564). The prevalence of discomfort was high among the students. Therefore, a recommended chair dimension was recommend for the use in hostels to avoid the increasing of risks among the students.

Abstract

This paper reviews the importance of incorporating human factors and ergonomics (HFE) in the development of Malaysian green buildings. Apparently, the development of green buildings is often focussed on achieving energy efficiency, low carbon emission, and lower operation and maintenance cost. However, green buildings should not only be environmentally and economically sustainable. Instead, it should also be socially sustainable. Social sustainability is connected to HFE and this could help to improve the quality of green development. It is imperative to consider HFE in green buildings as it is a discipline related to the understanding of the interaction among humans and other elements of a system in order to optimise human well-being and overall system performance. However, many tend to overlook the importance of human factors in green buildings and this may lead to some of the green features failed to be implemented, performed or not utilised in a way that maximises the performance of green buildings, thus restraining the green features’ usability and their potential benefits. Therefore, based on literature review, this paper reviews the need to incorporate human factors in the green building development and how this could benefit to improve the performance of green buildings in the Malaysian context. The findings show that HFE is still in its infancy stage in Malaysia. HFE is mostly implemented in the workplace focusing on occupational safety and health to reduce musculoskeletal disorder, risk, absenteeism and illness. The findings presented in this paper could create awareness among the practitioners on the benefits of creating flexible and ergonomic green buildings that accommodate building users, promote a healthy, comfortable and productive environment.

Abstract

The objectives of this study are to determine the prevalence of carpal tunnel syndrome (CTS) among the frontline counter workers and the associated risks. A cross sectional study was conducted among 100 frontline counter staffs whose working at the telecommunication company in Klang Valley area. A stratified random sampling was used to select the respondents. Respondents were interviewed by using structured questionnaire and Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). The structured questionnaire is used to determine demographic data, meanwhile CMDQ is to measure the discomfort of both right and left hands. A Rapid Office Strain Assessment (ROSA) is designed instrument to quantify exposure to office work environment. ROSA is a picture based posture checklist to obtain the risk level of workstation. The finding revealed that the prevalence of CTS among counter workers of the telecommunication company was 63%. Chi Square test indicated that there was no association between sociodemographic factors for age, gender, BMI, and race except marital status and education level with p>0.05. On the right hand, nearly 53% of the respondents had discomfort on the index and middle finger (χ²=8.45, p=0.07), 31% on the ring finger and pinkie (χ²=6.97, p=0.13), 42% on the distal thumb (χ²=1.93, p=0.75), 38% on the hand and metacarpal area (χ²=7.36, p=0.12), 53% on the thumb base (χ²=3.95, p=0.41), and 40% reported discomfort on the heel of hand (χ²=4.50, p=0.34). There was no significant association between office work design and CTS. This study found that the counter workers in telecommunication company reported high case of CTS. The prevalence of CTS was high however showed no association with the workstation assessment among counter workers area.

Abstract

Purpose: Elderly taxi drivers among the whole taxi drivers are rapidly growth in Malaysia. The older taxi community may continue to serve their service even after retirement age of sixty years old. Therefore, older taxi drivers need to take specific consideration during driving activities according to ability and capability to sustain their life and minimizing injuries and avoiding accidents. 

Objective: This study is aimed to determine the characteristics and discomfort seating posture among elderly taxi drivers. 

Methodology: A pilot study was conducted with elderly taxi drivers using a self-administered questionnaire. It included questions on socio- demographic data, work characteristics and discomfort seating posture of the affected body part. Purposive method sampling used base on inclusive criteria; age 60 years old and above, self-driving taxi more than 1 year, no disabilities and driving using a national car. SPSS software used to analyse data. 

Results: The majority were employed by companies (59.1%) and worked more than eight hours daily (90.9%). The majority (95.5%) driving distance more than 150km per-week. More than half respondents (59.1%) having feeling back pain past 12 months. The highest feeling of discomfort on seating posture among elderly taxi drivers is at right buttock (50.0%) and left buttock is only (45.5%). At the lower back body parts indicates the highest (36.4%) discomfort on seating posture compares to other parts.

Conclusions: An elderly taxi drivers potentially having MSD causes of current car seat design and the seating posture may not follow ergonomics principles. Most of the respondents had low awareness of important seating posture to improve their lifestyle and health.

Abstract

OBJECTIVE: This study aims to develop a recommended permissible weight standard for different types of lifting, horizontal distances, gender and body mass index (BMI) among Asian population. 

METHODOLOGY: This cross-sectional experimental study recruited 72 young adults using criteria of gender and BMI (underweight, normal and overweight). Two sessions were used 1) first session is to determine maximum lifting strength (MLS), 2) second session is to determine the maximum acceptable weight to lift (MAWL). Both sessions need the respondents of two-handed exertions in four lifting types (back lifting, upper-body lifting, arm lifting and shoulder lifting) across two horizontal distances (toes aligned with and posterior to the exerted handle). Total of 8 lifting tasks were performed by each of respondent in each session. Wilcoxon sign test was used to compare between MLS and MAWL and Kruskal-Wallis test to compare MLS and MAWL between 3 different BMI. 

RESULT: For all different types of lifting and horizontal distances shows that there is a significantly higher MLS compared to MAWL (p<0.05). Male respondent had a significantly higher (p<0.05) MLS and MAWL compared to female for all types of lifting and horizontal distances. Respondent with higher BMI had significantly higher (p<0.05) MLS and MAWL compared to underweight and normal. The study showed that the maximum weight lifted and acceptable weight for lifting is at upper-body compared to back, arm and shoulder lifting types. The recommended acceptable weight to lift for male upper-body is 17.8 ± 3.5 kg and for female is 11.3 ± 4.0 kg. 

CONCLUSION: Recommended that lifting use acceptable weight limit compared to maximum weight limit. Permissible weight standard should consider gender, BMI, horizontal distances and lifting types.

Abstract

One of the main challenges that hugely effect readers’ performance is cognitive load. It plays a pivotal role to facilitate readers to learn, memorize, and digest a piece of novel information. However, cognitive load can also have insignificant impacts on reading task when the cognitive demands of the reading task when to solve a complex problem. This article proposed a computational model of cognitive load during reading task, based on Cognitive Load theory, to get deep understandings on the dynamics of cognitive load and how the different types of load like intrinsic, extraneous and germane load are affecting the level of cognitive load. A number of simulation experiments were conducted and the results showed that the model is able to produce realistic behaviours under different personalities and conditions. Furthermore, an automated verification was implemented to evaluate the model.
