2082 | 2023 Article | Digital pedagogy policy in Technical and Vocational Education and Training (TVET) in Malaysia: fuzzy delphi approach Mohd Ridhuan Mohd Jamil Digital platforms are one of the technology adoption that is beginning to be used in most vocational colleges today. Services provided through digital platforms are an alternative to conventional methods. However, the use of digital platforms nowadays, among users consisting of vocational college students in Malaysia is still at a less than satisfactory level. Previous studies also focused a lot on the use and acceptance of technology platforms among users in schools only but not in vocational colleges (VC). The aim of the research is to determine the experts consensus on the objective of the digital pedagogy policy for Technical Education and Vocational Training (TVET) students especially in vocational colleges which is currently under development. Vocational colleges is one of the Technical Education and Vocational Training (TVET) institutions in Malaysia that offers certificate level and skill diploma education to high school students. Therefore, it is important to identify the poli..... 237 hits |
2083 | 2023 Article | Rules-based optimal mitigation of economic uncertainty Gan Pei Tha A notable attribute of the empirical studies on monetary rules is that few published articles rely on the normative evaluation in eliminating unwanted economic uncertainty. To prevail over this shortcoming, this paper introduces the optimal mitigation of economic uncertainty and determines its applicability through a sample of 14 selected countries. Using the combination of the theoretically derived optimal mitigation of economic uncertainty with the empirical estimations leads to specific monetary rules. The findings of this paper provide some policy implications; the optimal mitigation of economic uncertainty can characterise the optimal use of the interest rate and exchange rate to eliminate economic uncertainty and serve as a monetary policy guide in the adjustment process to restore macroeconomic conditions of the equilibrium that eventually promote the best macroeconomic outcomes.

2084 | 2023 Article | Essential oil composition, anti-tyrosinase activity, and molecular docking studies of Knema intermedia Warb. (Myristicaceae) Wan Mohd Nuzul Hakimi Wan Salleh Knema is one of the genera in the Myristicaceae family. The genus includes 60 species in Southeast Asia and is traditionally used for treating skin disorders. Here, for the first time, the essential oil, anti-tyrosinase, and molecular docking studies of Knema intermedia were evaluated. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Anti-tyrosinase activity was evaluated against mushroom tyrosinase, whereas molecular docking studies were performed using Autodock vina embedded in PyRx to evaluate the binding interactions of major components. A total of 37 components (97.3%) were successfully identified in the essential oil, which was characterized by high amounts of t-muurolol (20.1%), ?-copaene (14.4%), ?-cadinene (13.9%), germacrene B (9.5%), and ?-selinene (7.0%). The essential oil displayed moderate inhibitory activity towards tyrosinase with an IC50 value of 70.2 ?g/mL. The ..... 168 hits |
2085 | 2023 Article | Influence of mixed modifier fluoride on tuning the AC and dielectric properties of xBaF2(50x)CaF250B2O3 glass system Muhammad Noorazlan Abd Azis This study examined the effect of mixed alkaline earth modifier fluoride on AC conductivity and dielectric properties in xBaF2–(50–x)CaF2–50B2O3 (x = 5–35 mol%) glass system. The impedance data showed a single-depressed semicircle with decreasing bulk resistance (Rb) with temperature. The change of σAC implied a non-linear relationship with BaF2, which induced a blocking effect on the mobility of the charge carriers at x ≤ 20 mol%, indicating the Mixed Alkaline Earth Effect (MAEE). The abrupt increase at x = 25 mol% was associated with the expansion of the glass network due to the formation of Non-Bridging Oxygen (NBO). All glass samples followed the Overlapping Large-Polaron Tunneling (OLPT) model for the conduction mechanism. The change in ε′ more prominent in low-frequency regions, signifying that polarization was contributed mainly by the space charge polarization. Electrical modulus analysis revealed non-Debye type relaxation, indicating temperature- and composition-..... 160 hits |
2086 | 2023 Article | The early reception of tash aws narrative in Malaysia: an ecocritical interpretation of harmony within dissonance in the harmony silk factory Mohsen, Hamoud Yahya Ahmed This article is part of the current ecocritical research that is being conducted on Tash Aw's works. It attempts to analyse Tash Aw's first novel The Harmony Silk Factory and investigate how he customizes the concept of harmony and dissonance in relation to human beings from the perspective of the recent and growing theory of ecocriticism. Through examining Aw's novel, the manipulation of nature in the hope of illustrating the plot of a novel is studied thoroughly. In this article, the ecocritical theory is used to approach the phenomenon of harmony and dissonance in nature in the context of human-nature relationship in the chosen novel. The ecocritical theory assists in revealing with what perspectives the nature is portrayed by Aw in his first novel. The analysis of the novel reveals that there is a coherent harmony in dissonance in the bridge between human beings and their natural setting with the idea that human beings and nature are constantly influencing each other and causing di..... 176 hits |

2088 | 2023 Article | Journeying through time: exploring the 19th century old transportation legacy of weld quay, Malaysia Muhammad Zaffwan Idris Cultural heritage is an extensive body of knowledge that encapsulates the historical and cultural context of a sites creation and its present actualisation. While existing studies have defined traditional transportation, they have also recognised its importance as both tangible and intangible heritage, leading international organisations to advocate for its preservation. The tangible aspects pertain to the physical artefacts of the transportation vehicles, and intangible aspects refer to the cultural and historical context in which the transportation artefacts were used. In this study, we aim to explore the anthropological aspects of digitally preserving the historical and cultural context of significant transportation in a multi-cultural trading port. Primary sources were gathered through narrative interviews with individuals who have knowledge of the old transportation situations in Weld Quay, a cultural heritage centre from the 19th century. Secondary sources, including relevant and..... 180 hits |
2089 | 2023 Article | N-methyl costaricine and costaricine, two potent butyrylcholinesterase inhibitors from alseodaphne pendulifolia gamb Mohd Azlan Nafiah Studies have been conducted over the last decade to identify secondary metabolites from plants, in particular those from the class of alkaloids, for the development of new anti-Alzheimers disease (AD) drugs. The genus Alseodaphne, comprising a wide range of alkaloids, is a promising source for the discovery of new cholinesterase inhibitors, the first-line treatment for AD. With regard to this, a phytochemical investigation of the dichloromethane extract of the bark of A. pendulifolia Gamb. was conducted. Repeated column chromatography and preparative thin-layer chromatography led to the isolation of a new bisbenzylisoquinoline alkaloid, N-methyl costaricine (1), together with costaricine (2), hernagine (3), N-methyl hernagine (4), corydine (5), and oxohernagine (6). Their structures were elucidated by the 1D- and 2D-NMR techniques and LCMS-IT-TOF analysis. Compounds 1 and 2 were more-potent BChE inhibitors than galantamine with IC50 values of 3.51 0.80 M and 2.90 0.56 M, respectively. ..... 121 hits |
