Identifying relationship involving learning styles and problem solving skills among vocational students

Mohamad Mimi Mohaffyza, Yee Mei Heong, Rajuddin Muhammad Rashid, Tee Tze Keong,

Abstract

The purpose of this study was to determine the relationship between students’ learning styles and problem solving skills among students in Building Construction Course at Vocational School. This study also investigated the differences between the students’ type of learning styles and their ability to solve the problem using their creative thinking. A survey was carried out on 68 vocational students in Building Construction Course from two Vocational Schools. Felder-Soloman’s Index of Learning Styles (ILS) and elements of creative thinking in problem solving for Vocational Education were the tools used in this study. Creative thinking in problem solving elements was categorized from the subject specification used in Building Construction curriculum. In brief, the ILS have five dimension; Processing, Perception, Input, Understanding and Perception. The results show that the Input style dominates the learning styles of Building Construction’s students in Vocational School and mani.....

Culture medium and varietal selection for establishment of callus culture of Artemisia annua

Chin, Chee Keong

Abstract

Plant tissue culture technology offers the potential of producing medicinally important secondary metabolites such as anti-malarial artemisinin from Artemisia annua. In this study, callus induction of three different varieties of A.annua, namely T1, T2 and Hi varieties was carried out using leaf explants on Murashige & Skoog (MS) and Litvay (LV) media with three different supplementations. MS medium added with 0.5 mg/L BA, 0.5 mg/L NAA and 0.5 g/L of casein hydrolysate (CH) induced the highest yield of callus biomass compared to the effect of picloram- or 2,4-enriched MS medium. T2 variety was found to be the highest yielding variety in this medium. Picloram-enriched MS medium induced better callus in term of callus biomass and friability than 2,4-enriched medium. Hi variety induced in MS medium added with 0.5 mg/L picloram produced highest callus biomass among the three varieties. Callus formed on 0.5 mg/L picloram was also much more easily dispersed than callus of all three varieties.....

Optimal preservation and storage regimes of total RNAs from different fish tissues

Keong, Bun Poh

Abstract

Standardized and optimized methods in preservation and storage of RNA samples on three different tissues were elucidated on fish tissues. The treatments used included excision of fresh tissues, preservation of tissues by immersing completely in RNAlater followed by immediate freezing at -80°C prior to RNA assays. Current data suggests that preserving fish tissues in RNAlater with subsequent storage at -80°C produced satisfactory amount of RNA from dorsal fin and gonad, but not from muscle tissues. The optimized method will provide an alternative storage method option and enables greater usage of RNAlater for preserving RNA from animal cells...

Comparative transcriptomic study of matured fruit and post-fruit developmental stages in Malaysian durian varieties

Poh, Keong Bun

Abstract

Durian (Durio zibethinus Murr.) is a famous tropical fruit in Malaysia and well-known for its sweet and creamy taste and unique strong aroma. Despite the differences, durian fruit undergo similar fruit developmental stages upon maturity. However, not much information related to metabolic changes at molecular level are available for fruit development in durian. Hence, the aim of this study was to identify and analyze fruit development transcriptomic changes on six commercial durian varieties (D24, D99, D160, D168, D197, and D200). The transcriptome analysis via RNA-seq assays generated 67 to 234 million raw reads, which are assembled into 49,601 genes with protein coding genes as the largest gene biotype, with a total of 35,832 genes (72.2%). All genes were annotated against Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). GO analysis revealed genes were highly linked to biological process, cellular components and molecular function, with the highest representation.....

Legal and Shari’ah Issues in Takaful agents in Malaysia: an overview

Hal, Lai Keong

Abstract

This article aims at inter alia highlighting some important legal issues pertaining to Takaful agents in Malaysia. With the Takaful industry transcending the conventional insurance market locally and globally, Takaful agents have become an important tool in the recent development in the Takaful industry. Hence, the discussion will touch on the legal and Shari_ah position and the rights and liabilities of the Takaful agents parallel to promote and protect and maintain Takaful agents. This article fills that gap by providing specific recommendations regarding to Takaful agents in the Takaful industry. This article is intended to outline a more realistic and nuanced view, based on law and Shari_ah analytical techniques. It is intended to suggest the reasons why legal framework could be an appropriate platform to determine these issues on Takaful agents. Insofar as the current law_s definition of Takaful agent was ambiguity. Yet, there is no legal framework solely supervises the Takaful ag.....

Ploidy detection, genetic diversity, and quantitative trait loci mapping in molly fish (Poecilia spp)

Keong, Remmy Bun Poh

Abstract

A study was conducted to construct a preliminary linkage map for molly, Poecilia and to test association between markers and QTL traits. In I inkage map construction, three major steps were involved. First is the development of mapping population. Background genetic information of the parental species such as occurrence of triploidy and genetic variability were crucial before any attempt to develop a mapping population. Triploid detection was carried out in this study by using highly polymorphic microsatellite (SSRs) primer pairs. Ten SSRs primer pairs could clearly differentiate among one, two and three alleles which could be used to infer different ploidy levels. The presence of two alleles indicates a diploid at that particular locus and evidence of three alleles could be inferred as triploid. If such association was direct, the occurrence of triploidy in molly fish sampled in this study was extremely low and negligible......
