Background: Low birth weight (LBW) is a well-known factor associated with neonatal mortality and has contributed to a range of poor health outcomes. Thus, the objective of this study was to determine factors associated with LBW infants. Methods: A matched case control study was conducted in Universiti Kebangsaan Malaysia. Data of deliveries were obtained from Total Hospital Information System and medical records. All registered deliveries from January to June 2012 were used as sample populations. There were 180 pairs of cases and controls matched on babies’ gender. Fourteen variables were analyzed: maternal age, ethnicity, gravida, parity, gestational age, maternal booking weight, height and body mass index (BMI), history of low birth weight infants, birth interval, booking hemoglobin levels, hypertension, diabetes mellitus and mode of delivery. Results: Younger mother (t = 6.947, p < 0.001), lower booking BMI (t = 3.067, p = 0.002), prematurity (t = 12.324, p < 0.001), history of LBW infants (OR = 3.0, p = 0.001), LSCS (OR = 0.06, p = 0.001) and current hypertension (OR = 3.1, p = 0.008) were found significant in bivariate analysis. Multivariable conditional logistic regression identified younger maternal age (AOR = 2.9, 95% CI = 1.86 -4.51, p 13.58, p = 0.045), prematurity (AOR = 2.4, 95% CI = 1.79 -3.26, p < 0.001), and current hypertension (AOR = 4.5, 95% CI = 1.06 -19.22, p = 0.041) as significant factors associated with LBW infants. Conclusion: Younger maternal age, history of LBW infants, prematurity and hypertension have been recognized as predictors of LBW infants. The importance of pre-pregnancy screening, early antenatal booking and proper identification of high risk-mother needs to be strengthened and enforced in effort to reduce incidence of LBW infants.

Mechanical and Adhesion Properties of UV Curable Coating Based from Epoxidized Oil

引用

材料科学与工程（中英文B版） 2011年第4期1卷 452-456页

In this research, epoxidized oil (EO) has been exploited as a raw material in epoxy resin production. Epoxy resin produced from EO can be used for specific applications such as in coating industry. Conventional epoxy resin was said to be hazardous to human and is rather costly. On the other hand, EO which is sustainable from nature and cheaper, exhibits excellent properties such as adhesion to various substrates, good pigment wetting properties and thermally stable. The aim of this research is to substitute raw material of epoxy resin with epoxidized oil that exhibits similar properties as the conventional one. UV curable coating was prepared by copolymerization of EO with different monomers. Formulated resin was then applied on glass substrate and cured by ultraviolet (UV) radiation. From test performed, UV curable coating EO was found to possess excellent adhesion and scratch resistance. Coating samples have high adhesion force and passed high pencil grade. Hardness of this epoxidized system is high; all has minimum hardness of 5B while it has low volatile organic compound (VOC) about 2% due to probably residual monomers. The system is solvent free and is an energy efficient coating. EO can be potential material for UV curable epoxy system suited to be applied for coating with different hardness and mechanical properties.

Aerobic Degradation Process in Palm Oil Mill— Issues, Challenges and Upsurging Its Efficiency through Bioremediation

Palm oil mill effluent (POME) is liquid waste produced from palm oil extraction process. Discharging it to the river without treatment is violation according to Malaysia Environment of Quality Act (EQA) 1974. In Malaysia, ponding system is a conventional treatment method for POME due to its economical and simple process. The treatment process mainly involves two main treatment phases;anaerobic and aerobic degradation. Anaerobic degradation has a proven track record in reducing pollutant properties in POME up to 85%. The real challenge is to increase the efficiency of aerobic process as the biological oxygen demand (BOD) discharge limit has been further reduced from 100 mg·L-1 to less than 20 mg·L-1. One of economical and feasible approach to increase the efficiency of aerobic phase is via bioremediation. This paper describes the limitation of aerobic degradation in ponding system, besides discussed on the important aspects that need to be optimized for a success implementation of bioremediation and its challenges.

Intraday Lead-Lag Relationship between Index Futures and Stock Index Markets:Evidence from Malaysia

引用

Journal of Modern Accounting and Auditing 2018年第10期14卷 561-569页

作者： Jude W. Taunson mohd. fahmi Bin Ghazali Minah Japang Abd. Kamal Bin Char Universiti Malaysia Sabah SabahMalaysia

This paper investigates the lead-lag relationship between the stock index futures(known as FKLI)and its underlying index,the Kuala Lumpur Composite Index(KLCI)in the emerging Malaysian *** 15-second interval data,cross-correlation,and the partial adjustment model,we find a bi-directional asymmetric lead-lag relationship and that the KLCI’s lead over FKLI is much *** evidence also suggests that the KLCI returns over-react to information,more so once thin trading effects are ***,the evidences suggest that traders prefer to exploit stock specific information in the underlying market despite the advantages of trading the index futures.
