Kajian  ini  adalah  satu  usaha  yang  dijalankan  untuk  mengetahui  sejauh  mana  tahap penggunaan Pengurusan Sistem Maklumat Pendidikan (EMIS) di sekolah seluruh Negeri Perak Darul Ridzuan. Dalam penyelidikan ini, kejayaan penggunaan EMIS dilihat dari segi manfaat  kepada individu dan organisasi. Reka bentuk penyelidikan ini adalah korelasi- deskriptif dan data  kuantitatif dikumpul dengan menggunakan soal selidik. Penyelidikan ini menggunakan teknik  pensampelan rawak strata untuk memilih 607 responden. Data kajian dianalisis dengan menggunakan  analisis deskriptif dan analisis regrasi berganda. Kajian ini mendapati empat daripada enam faktor  iaitu Kepuasan Pengguna EMIS (β = .45), Penglibatan Pengguna EMIS (β = .25), Kekuatan Sistem EMIS  (β= .24), Kefahaman Pengguna EMIS (β = .20) adalah faktor penyumbang yang signifikan kepada  kejayaan penggunaan EMIS dan menghasilkan persamaan regresi (Y-hatK-EMIS = -0.19 + 0.24(Kekuatan  Sistem (KS)) + 0.20(.....

The isolation and purification of the leaves of Kopsia singapurensisRidl. (Apocynaceae) revealed the presence of steroids, terpenes, and alkaloids. Stigmasterol 1 was isolated from the hexane crude extract of the leaves of this species. This phytochemical study involves extraction, separation by using various chromatographic methods and structural determination by spectroscopic technique such as IR, NMR including 1D-NMR (1H, 13C and DEPT), 2D-NMR (COSY, NOESY, HMQC/HSQC, and HMBC) and GCMS, involving also comparison with data from the literature..

A phytochemical investigation of the bark of Alseodaphne peduncularis (Wall. Ex. Ness) Meissn (Lauraceae) has resulted in the isolation of a known aporphine alkaloid; boldine (1). The isolation and purification of the alkaloids were achieved using column chromatography (CC) and preparative thin layer chromatography (PTLC). The structural elucidation was performed by spectral methods mainly 1D and 2D NMR, IR, UV and MS, and in comparison with data from other literature...

Kajian ini bertujuan membentuk instrumen untuk mengenal pasti motif penglibatan remaja dalam bidang sukan. Instrumen Motif Penglibatan Sukan (MPS) dibina melalui dua fasa penyelidikan iaitu fasa penggubalan item dan ujian psikometrik instrumen. Pengubalan item soal selidik dilakukan mengikut proses Nominal Group Technique terhadap remaja yang aktif dalam sukan. Sebanyak 75 item telah terhasil daripada fasa penggubalan item soal selidik. Analisis faktor dan nilai pekali Alpha Cronbach digunakan untuk menguji bilangan faktor dan kebolehpercayaan dalaman data. Soal selidik MPS telah ditadbir ke atas 582 orang remaja yang aktif bersukan bagi mendapatkan analisis faktor dan kebolehpercayaan instrumen. Hasil proses analisis komponen prinsipal soal selidik MPS mempunyai 58 item merangkumi sembilan faktor iaitu Menaikkan Nama Negara, Kesihatan dan Kecergasan, Peningkatan Kemahiran, Inginkan Cabaran, Inginkan Kejayaan, Kebanggaan Keluarga, Kebanggaan Diri, Kestabilan Emosi dan Jaminan Masa Depa.....

Mobile Multihop Relay (MMR) network is an attractive and low-cost solution for expanding service coverage and enhancing throughput of the conventional single hop network. However, mobility of Mobile Station (MS) in MMR network might lead to performance degradation in terms of Quality of Service (QoS). Selecting an appropriate Relay Station (RS) that can support data transmission for high mobility MS to enhance QoS is one of the challenges in MMR network. The main goal of the work is to develop and enhance relay selection mechanisms that can assure continuous connectivity while ensuring QoS in MMR network using NCTUns simulation tools. The approach is to develop and enhance a relay selection for MS with continuous connectivity in non-transparent relay. In this approach, the standard network entry procedure is modified to allow continuous connectivity with reduced signaling messages whenever MS joins RS that is out of Multihop Relay Base Station (MRBS) coverage and the relay selection is.....

The leaves and stem bark extracts of B. penangiana were screened to evaluate their antioxidant, antimicrobial,tyrosinase, lipoxygenase, and acetylcholinesterase activities. Evaluation of antioxidant activities were tested against DPPH, ABTS, and total phenolic content (TPC) assays. The antimicrobial activity were investigated by microdilution method for determination of MIC, MBC, and MFC. Tyrosinase and lipoxygenase inhibitory activities were analysed using mushroom tyrosinase and lipoxygenase enzymes, respectively. In addition, the acetylcholinesterase activity was tested using cholinesterase enzyme. The methanol extract of stem bark showed the highest phenolic content (176.8 mg GAE/g), DPPH free radical scavenging (IC50 95.5 μg/mL), ABTS (IC50 124.8 μg/mL), and lipoxygenase inhibitory activity (I: 46.3%). All extracts showed from moderate to weak activity with MIC/MBC/MFC values in the ranged of 62.5-1000 µg/mL. The ethyl acetate stem bark extract revealed the highest percentage i.....

Murraya koenigii (Rutaceae), locally known as curry leaf tree, is a medicinally important herb of Indian origin and now is widely distributed throughout southern Asia. The bark of Malayan Murraya koenigii was investigated for phytochemical content. The isolation of chemical constituents from its hexane extract was carried out by using various chromatographic techniques. Spectroscopic methods, including NMR, IR, UV, MS spectra data, were used for the structural characterization. Four C23-carbazole alkaloids were isolated..
