    Repetitive Strain Injury (RSI) is the most common occupational injury faced by computer users. Computer users faced
    higher possibility of getting RSI due to their prolonged working time and static posture. The three main objectives of
    this study are, first: to identify the prevalence of RSI among computer users; second, to investigate and determine the
    RSI risk factors; and third to analyze the association between RSI risk factors and the prevalence of RSI among computer
    users at a Telecommunication Company X. A total of 100 respondents were selected based on their daily exposure to
    computer usage of more than 4 hours. Nordic modified questionnaire was used to gather respondents’ sociodemographic
    data, job’s information, physical risk exposure, physical symptoms and their awareness level towards RSI.
    Body Parts Symptoms Survey (BPSS) form were also used to identify the body parts exposed to the RSI risk among
    computer users. The data was analysed using Statistic Package for Social Science (SPSS) version 22. Study results showed
    that the 41% of computer users in Telecommunication Company X felt tired at the upper-back near the neck and 38%
    at the shoulder region. In conclusion, the prevalence of RSI among computer users is high at upper back near the neck
    and at the shoulder region. There is a significant association between risk factors of RSI and the prevalence of RSI
    among the computer users at Telecommunication Company X.

    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.

    This paper reviews various papers since the year 2000 until 2016 regarding visual technology in human anthropometry
    study, and discusses three major points; (1) the methods and objectives of the research, (2) the subjects of the
    experiments and (3) body parts involved in the anthropometrical measurements. Measurement using visual
    technology is claimed to be more accurate in obtaining anthropometrical data compared to the conventional method
    using manual tools. However, commercial visual technology system can be very costly. Based on the reviewed
    studies, a significant amount of research has adopted various visual processing methods to predict the human’s body
    measurement. All of the studies utilized the applications of enhanced technologies that are able to reduce time and
    human errors that normally occur during traditional hand-operated measurement. Usually, in order to prove that
    their result is promising, the studies compared their results with the results gained from manual measurement. The
    finding from this review is a preliminary step towards developing a camera-based system in anthropometry
    measurement for the use in automotive ergonomics design.

    Awareness of occupational noise and its effects is growing. At No. 11 squadron base, Sukhoi jet was identified as the main culprit of occupational noise that affects not just the employees of the base but also civilian people in the surrounding area. The objective of the study is to identify the noise level produced by Sukhoi two-engines jet during maintenance operations. Investigations were carried out using Bruel & Kjaer 2250 sound level meter hand-analyser. Measurements were performed directly under the Sukhoi jet body and then 10 metres, 50 metres, 100 metres, 1000 metres and 1500 metres away. The jet engines could operate at two levels, at 72% RPM and at 85% RPM. The civilians are only exposed to its noise from more than 1000 metres away. The results from this study are analysed and noise mapping and noise contouring are produced which give the level of noise exposure. The maximum noise is recorded t 122dB(A) and the minimum is at 60dB(A). The farther the noise from the jet is measured, the lower the values recorded. From the noise mapping, the effects of noise exposures on both the employees at the base and the civilian at the neighbouring surrounding could be identified. Even though the exposures are only for 5-10 minutes, it is still considered as a threat
