Source of apportionment of air quality parameters at federal port of Malaysia with emphasis on ship emission
No full textAir pollution is becoming a major environmental issue in Malaysia. Centered on data obtained from the
Malaysian Department of Environment (DOE), this analysis focused on identifying possible causes of
air quality heterogeneity across the research area. 14 air quality parameters in 7 monitoring stations for
ten years (2009-2018) were gathered. To determine the source of air pollution around the study region,
the Principal Component Analysis (PCA) approach from a chemometric methodology was applied. The
PCA method has identified three varimax factor (VF) with 11 air quality parameters are the most
significant parameters around the study area. It can be inferred from the analysis that the use of the
PCA approach in chemometric techniques can be applied for the purpose of source apportionment. Accordingly, this study suggested that efforts should be put as a priority in the monitoring of ships
emissions sources in Malaysia Federal Ports area and successful management of Malaysian air quality

The challenges in implementing mixed economy of care practices in child welfare network in Malaysia
No full textThe Social networks play a very important role in the well-being of children. This is because; the welfare network
serves as a charitable service provider to meet their needs. Child welfare networks include family members, children,
schools, peers, neighbors, community members and institutions offering health, education, health, food and drink
services, love, safety, protection and a healthy environment. This article describes the network mapping of child
welfare services in the custody of public institutions. A study was conducted to explore the practice of implementing
the welfare services network of children at STB Marang, Terengganu Malaysia using the qualitative design of the
Grounded Theory to obtain the raw data. A set of interview protocols have been developed as a guide to conducting
face-to-face and deep interviews with 30 respondents of 24 different agencies. The main findings of the study found
that although public custody in Malaysia practiced a mixed economy of care approach, service network operations
were in conflict with the mixed economy of care approach adopted. As a follow-up to the findings of this study, the
Social Network Development Model was developed. This model can be a productive tool in developing an integrated
welfare network for children in Malaysia

Diversity and abundance of hymenopteran parasitoids at two different elevations in Redang Island, Terengganu, Malaysia
No full textA study was conducted to determine the diversity and abundance of hymenopteran parasitoids in two
different elevations of the coastal and inland forest of Redang Island, Terengganu. Three Malaise traps
were installed at each three sampling points in both plots, respectively. The insect samples were collected
after seven days and brought to the laboratory for sorting, enumeration, and identification process up to
family level. The abundance of parasitoids between two plots was compared using T-test analysis while
the comparison of hymenopteran parasitoids abundance between different families was analysed using
one-way Analysis of Variance (ANOVA). The insect diversity was analysed using the Shannon-Weiner
Diversity Index (H’). Overall, there were 48 individuals of parasitoids from 13 families were collected and
no significant difference (P>0.05) of parasitoids abundance between both plots. However, the parasitods
population in inland forest was more diverse (H’=1.58) compared to the coastal forest (H’=1.42). Thus,
there was a significant difference (P<0.05) of parasitoids abundance among the 13 different hymenopteran
families. The most abundant family was Braconidae with 24 individuals followed by Ichneumonidae with six
individuals whilst the least abundant families were Elasmidae, Mutillidae, Diapriidae, Chalcididae,
Eulophidae, Pompilidae, Chrysididae, and Platygastridae with only one individual, respectively. In
conclusion, the diversity of hymenopteran parasitoids in the inland forest was higher than coastal forest
although the abundance was not significantly different. Other parameters such as vegetation species and
distribution, and abiotic factors should be considered in future studies in order to d
