Kajian ini dijalankan untuk menentukan kesan   penggunaan Token Ekonomi untuk meningkatkan pencapaian, motivasi dan penglibatan murid dalam pembelajaran Bahasa Melayu di sebuah  Sekolah Jenis Kebangsaan Cina. Pendekatan kuantitatif dengan reka bentuk kuasi eksperimen digunakan  dalam kajian ini. Data daripada pemerhatian dan temubual juga digunakan untuk menyokong data  kuantitatif. Pemilihan subjek kajian melibatkan 63 orang murid tahundua di sebuah sekolah Daerah  Klang, Selangor. Subjek kajian terdiri daripada 31 orang murid kumpulan rawatan dan 32 orang murid  kumpulan kawalan. Data kuantitatif diperoleh daripada ujian pra dan pasca, soal selidik dan kuiz,  manakala data kualitatif diperoleh daripada pemerhatian dan temu bual. Data dianalisis dengan  menggunakan analisis deskriptif dan inferens. Analisis deskriptif menjelaskan kekerapan, min,  sisihan piawai, manakala statistik inferens melibatkan ujian-t bebas. Dapatan kajian mendapati  bahawa terdapat peningk.....

This study aims to investigate the phytochemicals and biological activities from the bark and leaf of Aquilaria subintegra Ding Hou. The samples were air-dried, ground, and gradient  extracted by cold extraction using n-hexane, dichloromethane, and methanol successively.  The  bark   and  leaf  crude  extracts  were  purified  via chromatographic techniques to produce pure  compounds. The chemical structure of compounds were determined using spectroscopic methods such as  nuclear magnetic resonance, ultraviolet, infrared, mass spectrometry and comparison from the  literature review. The crude extracts and isolated compounds were tested for their anti-lipase,  antioxidant and anticancer activities through colorimetric test, DPPH free radical scavenging and  cytotoxicity assay, respectively. This study has successfully afforded 22 compounds, including  three new compounds, namely aquilene A, aquilene B, and subintegranol.  Other compounds were  5-hydroxy-7,4Ê.....

Topic theory in musicology examines how musical elements and structures convey emotions or topics in music. Despite its potential to provide a framework for understanding musical expression, topic theory has rarely been applied to piano pedagogy. This study aimed to explore participants’ perceptions of Raymond Monelle’s topic theory, specifically the hunt, military, and pastoral topics, in piano interpretation and teaching. Participants included six music lecturers from Chinese universities and nine university music students from Bulgaria, China, France, Germany, and the United States. Data was collected through a listening survey and semi-structured interviews and analysed using thematic analysis. The listening survey used excerpts from Dussek’s La Chasse, C.146, Beethoven’s Piano Sonata in A Major, Op. 101, Second Movement, and Liszt’s Années de Pèlerinage, Première année - Suisse, No. 3, Pastorale. The results showed that more than half of the participants matched the .....

Historically, notation in Southeast Asia has been used for musical documentation and preservation rather than functioning as a medium for realising music during performance. As a consequence, today both heritage and hybrid forms of script such as Balinese ding dong notation and Javanese kepatihan cipher notation play only a minor role in the musical expression of this region’s predominantly aural-based forms. When musical notation is used, it may be found written on a variety of traditional and modern medium including palm leaves and plain paper to computer programs with specialised fonts or even cell phone text messages. In this article, I observe notation in three distinct traditions existing along a continuum from preservation to innovation. Despite technological advancements and the availability of Western staff notation, diverse forms of indigenous musical notation primarily serve to sustain traditions and aide the memory of musicians for teaching and learning...

The present study reports on the isolation, purification and antioxidant activity evaluation of the dichloromethane extract of Aquilaria subintegra Ding Hou leaves. Four compounds were successfully isolated and purified from the dichloromethane extract using column chromatography. Purification was monitored by thin layer chromatography, and four isolated compounds were identified by spectroscopic analyses such as NMR and mass spectrometry. These compounds were 5-hydroxy-7,4'-dimethoxyflavone, luteolin-7,3',4'-trimethyl ether, ?-sitosterol and friedelin. Their antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH). All compounds exhibited weak antioxidant activity, with inhibition values of less than 30 % at the highest tested concentration (500 ?g/mL). To the best of our knowledge, the current study is the first to report on the DPPH radical scavenging activity of isolated secondary metabolites from A. subintegra leaves. 2024 Malaysian Institute of Chemistry.
