Thisstudy wascarried out to prepareepoxy/ natural hydroxyapatite composite  for  potential biomedical application. Natura hydroxyapatite (nHAp) powder was extracted fromTilapia fishscales via the thermal method. Thenatural hydroxyapatite wasmilled for48 hoursanddriedby spraymethod. The nHAp particle size wasdetermined using mastersizer 2000 particlesizeanalyser and the chemical structurewas confirmed using XRD) and FTIR analysis.The particle sizeof nHAp wasidentifiedto bebetween1 and 10microns. Mechanicalpropertiesof epoxy/ naturalhydroxyapatitewereinvestigated by using impactand flexunral test. The highest flexural strength ofepoxy/nHAp composite was recorded when the nHAp filler was10 wt%which is 77%incrementascomparedtoepoxyalone.Theimpactstrength was increased up to two-fold as compared to neat epoxy.The scanning electron micrograph (SEM) and EDX analysis showed uniform dispersion of nHAp particles within the epoxy matrix for the composites with 10 wt% filler loading..

The objective of this research is to investigate the relationship between hazard ratio or survival function of graduate employability and 8 explanatory variables. The 8 explanatory variables are as follows: gender, CGPA, geographic region, English language proficiency, area of study, curriculum satisfaction, carrier guidance services satisfaction and monthly family income. In order to study a survival function of graduate employability, we have developed a sequence of binary numbers (employed (1) or unemployed (0)) at a particular time of being employed among first degree graduate students (N=2228). The data is based on a survival study data, which traces the survival function of graduate students within 12 months of window opportunity. We have used the complementary loglog model in various forms. For the simple complementary log-log link model, the results showed that the hazard risk with baseline hazard ratio relate to graduates' gender, CGPA, satisfaction with career guidance, the g.....

Conjugation of poly(ethylene glycol) (PEG) to poly(lactide-co-glycolide) (PLGA) renders the latter with enhanced biocompatibility and broader overall capability in biomedical application. Novel miktoarm star polymers comprising PLGA and PEG segments are of interest for their potential as drug carriers. Thus, a series of miktoarm star copolymers, PLGA-(mPEG)2, with different PLGA arm molecular weights and methoxy-PEG (mPEG) arm (2000 g/mol), were synthesised via a four-step reaction using carbodiimide chemistry with a low steric hindrance trifunctional linker aminoadipic acid (AAA) and characterised by proton nuclear magnetic resonance (¹H NMR), fourier transform infrared (FTIR), gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). Results show that the miktoarm star polymers PLGA17.0-AAA(mPEG)2 and PLGA43.4-AAA(mPEG)2 formed stable nanoparticles and PLGA4.6-AAA(mPEG)2 self-assembled into stable nanomicelles. Fluorescence spectroscopy showed that the critic.....

Background This study aimed to observe the cartilaginous matrix production in SRY (sex determining region Y)-box 9 (SOX9)- and/or telomerase reverse transcriptase (TERT)-transfected chondrocytes from monolayer to three-dimensional (3D) culture. Methods The genes were transferred into chondrocytes at passage-1 (P1) via lipofection. The post-transfected chondrocytes (SOX9-, TERT- and SOX9/TERT) were analysed at P1, P2 and P3. The non-transfected group was used as control. The 3D culture was established using the chondrocytes seeded in a disc-shaped PLGA/fibrin and PLGA scaffolds. The resulting 3D “cells-scaffolds” constructs were analysed at week-1, -2 and -3. The histoarchitecture was evaluated using haematoxylin and eosin, alcian blue and safranin o stains. The quantitative sulphated glycosaminoglycan (sGAG) content was measured using biochemical assay. The cartilage-specific markers expression were analysed via real-time polymerase chain reaction. Results All monolayer cultured ch.....

This study aims to describe the process of the development of a creative drama module that could be used as tool for the socialization of learners with autism. Objectives of the study are to identify common socialization deficits of learners with ASD and to develop a module using drama activities.This descriptive study is conducted to investigate how drama activities could be used as tool to help learners with autism engage in social interaction. Data were collected through interviews,observations, and checklist analysis. Semi-structured questions were used in the interviews.Instruments used were interview questions, observation field notes and evaluation checklist.Descriptive analysis was used to examine thecollected data. Findings of the study show that learners with ASD share common deficits in socialization; drama activities are helpful in encouraging socialinteraction among learners with ASD and the module in creative drama could be used as a tool for the socialization. Im.....

Emphasizing only on intellectual intelligence without stressing on feelings and emotions could negatively affect an individual’s emotional development. Development of stable emotion regulation strategies is important for an individual to function appropriately in different contexts. Although there are many scales developed to measure emotional intelligence (EI), there is a dearth of instruments to measure EI in preschool children. One instrument that taps EI in preschool children is The Sullivan Emotional Intelligent Scale for Children (EISC). EISC was developed for use in the United States and there is no such instrument available in Malaysian context (to the best of our knowledge).The aim of the current study was to adapt EISC to measure Malaysian preschool children’s emotional intelligence. EISC was translated into Malay Language and the reliability value of the instrument was then tested using the Rasch Model. There are 50 respondents (preschool children) was random sel.....

Arabic language has long been established in the Republic of China along with the entrance of Islam. Among the regions in which the Arabic language teaching is available in China is the Ningxia region. Even though the Arabic language in the Ningxia region has begun for a long time, the Arabic language pass rate is still recording low percentage. Therefore, this study was conducted using a descriptive analysis pertaining to the problems of Arabic language learning among students at Ningxia University. In addition, the objective of this study was to identify the factors that caused the Arabic language learning problems among students at Ningxia University. The inductive method was used in the process of collecting information with regard to the Arabic language learning activities at Ningxia University. The quantitative approach in this study used a questionnaire instrument as the main instrument. The sample selection was carried out by means of a purposeful sampling involving.....

Students in higher learning institutes in Malaysia face some difficulties in expressing themselves in English language and show lack of competency in speech.They perform poorly in the English language during examination held in the university and also interviews. Based on the problems encountered by the weak students, it was deemed necessary to provide some form of guidance to enable the ESL students to speak confidently. The guidance comes in the form of a cooperative interactive learning module for teaching speaking to weak ESL students. The purpose of the study is to develop a cooperative interactive learning module as a teaching approach that could benefit ESL students at the university. This study also investigates the attitudes of the students before and after using the cooperative interactive learning module concerning speaking.The research comprises of two stages namely instructional design, ADDIE model (to develop the module). A quasi-experimental design was carried�.....
