Lunge and squat exercises are two exercises mainly used in strength training due to its multi-joint, structural and freeweights nature and benefits. Main aim of this study is to determine the effect of verbal and video-based mode of instructions on both exercises. Joint angles and muscle activation were measured as an indicator or determinants of the effect of the exercises. Thirty male participants were recruited and involved in two testing occasions. Results of the study indicated no significant differences for both exercises in term of all determinants measured. As a conclusion, mode of instructions may give variety to teaching and learning approach for both exercises, but it produces similar effects. Most important is to ensure in any mode of instructions utilized, the technical aspects given are based on correct biomechanical ques for optimal mechanical effect.  ..

Kajian ini bertujuan menentukan kesan Strategi Pengajaran GeoGebra (SPG) terhadap pencapaian murid Tingkatan 4, pencapaian konseptual, pencapaian prosedural, usaha mental dan kecekapan pengajaran dalam topik Persamaan Kuadratik. Reka bentuk kuasi eksperimen ujian pra-pasca kumpulan kawalan tidak setara dijalankan terhadap 60 orang murid Tingkatan 4 dari sebuah sekolah di daerah Kota Bharu, Kelantan. Dua kelas diagihkan secara rawak kepada dua kumpulan iaitu kumpulan rawatan yang menjalani SPG dan kumpulan kawalan yang menggunakan Strategi Pengajaran Konvensional (SPK) bagi topik Persamaan Kuadratik. Instrumen yang digunakan ialah Ujian Pencapaian Persamaan Kuadratik yang mengandungi soalan pengetahuan konseptual dan pengetahuan prosedural, dan Skala Perkadaran Usaha Mental. Data dianalisis menggunakan dua kaedah iaitu analisis statistik deskriptif dan statistik inferens. Analisis deskriptif melibatkan penggunaan min, sisihan piawai, frekuensi dan peratusan. Manakala analisi.....

Kajian ini bertujuan mengenal pasti pengaruh jantina, gaya kognitif dan personaliti warna terhadap pencapaian akademik pelajar. Kaedah tinjauan berbentuk Cross Sectional digunakan dalam kajian ini. Sampel kajian terdiri daripada 322 orang pelajar yang sedang mengikuti pengajian Diploma di enam fakulti Universiti Pendidikan Sultan Idris (UPSI). Instrumen Group Embedded Figure Test (GEFT) oleh Witkin et al., (1977) bersama Inventori Personaliti Warna oleh Sidek (2005) digunakan untuk mengumpul data kajian. Hasil kajian mendapati pelajar lelaki dan perempuan mempunyai gaya kognitif yang sama iaitu Bebas Medan, 2(1,N= 320) = 0.43, p =.511. Namun, kajian menunjukan terdapat perbezaan yang signifikan dari segi jantina pelajar dalam personaliti warna Hijau (t(320) = 1.89, p = .05) dan Emas (t(320) = -2.42, p =.01). Dapatan menunjukan bahawa gaya kognitif pelajar tidak mempunyai perbezaan signifikan dengan pencapaian akademik (t(320) = -.40, p =.685). Walau bagaimanapun, pencapaian.....

The objective of this study is to explore the factors that influence the academic performance of Libyan postgraduate students in selected Malaysia universities. A case study qualitative research design was used to answer four research questions. Open-ended  interview questions  were used to collect data from the 11 participants  as a sample of the study using a purposive sampling technique. The qualitative data analysis was used to reflect factors that influence the. academic performance of the participants. The results showed that academic satisfaction and self-motivation, customs, religion, and adaptation issues, and political situation in Libya and psychological tension are the contributing factors that influenced the academic performance of Libyan postgraduate students in selected Malaysia universities. The study also found that family responsibilities and psychological pressure, lack of English proficiency skills and academic stress, financial decision and fear of the future, f.....

Kajian ini bertujuan untuk membangunkan modul pengajaran STEM bagi bidang pembelajaran Statistik dan Kebarangkalian dalam KSSM Matematik Tingkatan Dua. Kajian pembangunan modul ini melibatkan proses kesahan, kebolehpercayaan dan kebolehgunaan modul. Modul ini dibangunkan berasaskan semua fasa dalam model ADDIE iaitu (A) analisis, (D) reka bentuk, (D) pembangunan, (I) pelaksanaan dan (E) penilaian. Modul ini juga diterapkan dengan konsep STEM serta teori pembelajaran berasaskan inkuiri. Proses kesahan modul dilakukan oleh empat orang pakar. Dapatan menunjukkan bahawa modul yang dibangunkan mempunyai kesahan yang baik dengan peratus persetujuannya adalah 92%. Seterusnya, modul ini diuji kebolehpercayaan dan kebolehgunaanya melalui kaedah tinjauan terhadap 42 orang guru Matematik sekolah menengah di daerah Kota Bharu, Kelantan. Dapatan menunjukkan kebolehpercayaan instrumen adalah baik dengan nilai Cronbach’s Alpha, 0.97. Manakala bagi dapatan kebolehgunaan modul pula menunj.....

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.....
