There has been a growing concern on the rising of environmental issues in Malaysia over the last decade. Many environmental studies conducted in this country began to utilise the chemometrics techniques to overcome the limitation in the environmental monitoring studies. Chemometrics becomes an important tool in environmental fields to evaluate the relationship of various environmental variables particularly in a large and complex database. The review aimed to analyse and summarize the current evidences and limitations on the application of chemometrics techniques in the environmental studies in Malaysia. The study performed a comprehensive review of relevant scientific journals concerning on the major environmental issues in the country, published between 2013 and 2017. A total of 29 papers which focused on the environmental issues were reviewed. Available evidences suggested that chemometrics techniques have a greater accuracy, flexibility and efficiency to be applied in environmental modelling. It also reported that chemometrics techniques are more practical for cost effective and time management in sampling and monitoring purposes. However, chemometrics is relatively new in environmental field in Malaysia and various scopes need to be considered in the future as the current studies focused on very limited number of major environmental issues. Overall, chemometrics techniques have a lot of advantages in solving environmental problems. The development of chemometrics in environmental studies in the country is necessary to advance understanding, thus able to produce more significant impacts towards the effective environmental management.

The purpose of this review is to provide the overview of available systems and potential future systems for communication during disaster in Malaysia. Electronic searches in major subject loci databases such as MEDLINE (via PUBMED), Ovid, Science Direct, Scopus, IEEE Xplore digital library and Springer are used in conducting the reviews. The major challenge is to integrate between readily available communications systems at pre-disaster, during disaster and post-disaster. Therefore, this review will further provide information for the policy makers, responsible personnel as well as researchers on the vulnerability of the communication systems during disaster and the future direction of effective communication system in Malaysia.

Body fat percentage is regarded as an important measurement for diagnosis of obesity. The aim of this study is to determine the association of high body fat percentage (BF%) and lifestyle among adult women. The study was conducted on 327 women, aged 40-59 years, recruited during a health screening program. Data on socio-demography, dietary intake and physical activity were collected through validated questionnaires. BF% was measured using InBody 270 Body Impedance analyzer machine. Association between lifestyle factors and body fat percentage were investigated using multiple linear regression, adjusted for age and body mass index (BMI). Intake of protein, calcium and physical activity on household intensity were the predictors of high BF%.
