| 1291 | 2024 Article | Chemical composition, anticholinesterase activity, and molecular docking studies of Piper baccatum Blume (Piperaceae) essential oil Wan Mohd Nuzul Hakimi W Salleh Piper baccatum is a woody climber and grows throughout the tropics mostly in Southeast Asia such as Thailand, Malaysia, Singapore, and Indonesia. The studies on essential oil composition and anticholinesterase activities were performed, along with molecular docking of all components. The essential oil was obtained by hydrodistillation and analyzed by GC-FID and GC-MS, while anticholinesterase activity was assessed using Ellman method. A total of 14 components were identified, representing 98.1% of the total composition of the essential oil. The major identified components were _-caryophyllene (30.7%), camphene (22.1%), eucalyptol (14.9%), _-muurolene (6.9%), and _-pinene (5.3%). A moderate inhibitory effect was observed for acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) with IC50 values of 80.5 and 96.4 _g/mL, respectively. Molecular docking studies of P. baccatum components with AChE and BChE revealed binding energy ranges of -5.6 to -8.5 Kcal/mol and -5.2 to -7.8 Kcal/m..... 50 hits |
| 1292 | 2024 Article | The effects of small-sided games on fitness components and technical abilities among youth soccer players Ali Md Nadzalan Small-sided games (SSG) is one of the increasingly popular training methods in developing fitness components and technical abilities among soccer players. The objective of this study is to investigate the effectiveness of SSG training on player_s fitness components and technical abilities after six weeks of training program among youth soccer players. Sixty youth soccer players (M = 19.98 years of age; SD = 0.97) were recruited in this study and were divided into SSG intervention group (IG, N = 30) and control group (CG, N = 30). Agility, speed, cardiovascular endurance, passing and dribbling tests were conducted pre- and post- six weeks of training. Results showed that there was a statistically significant difference in speed, passing, dribbling and VO2max in the post-test among the IG group. When compared to the CG, the IG showed better performance in speed, dribbling and VO2max as these had shown a significant difference between the two groups. In conclusion, SSG training method can..... 68 hits |
| 1293 | 2024 Article | High-resolution downscaling with interpretable relevant vector machine: Rainfall prediction for case study in Selangor Shazlyn Milleana Shaharudin Due to the discrepancy in resolution between existing global climate model output and the resolution required by decision-makers, there is a persistent need for climate downscaling. We conducted a study to determine the effectiveness of Relevant Vector Machine (RVM), one of the machine learning approaches, in outperforming existing statistical methods in downscaling historical rainfall data in the complex terrain of Selangor, Malaysia. While machine learning eliminates the requirement for manual feature selection when extracting significant information from predictor fields, considering multiple pivotal factors is essential. These factors include identifying relevant atmospheric features contributing to rainfall, addressing missing data, and developing a significant model to predict daily rainfall intensity using appropriate machine-learning techniques. The Principal Component Analysis (PCA) technique was employed to choose relevant environmental variables as input for the machine lear..... 178 hits |
| 1294 | 2024 Article | A systematic review of emerging trends in crop cultivation using soilless techniques for sustainable agriculture and food security in post-pandemic Monsuru Adekunle Salisu By 2050, the global population is anticipated to reach 10 billion, marking a significant 34% increase and raising concerns regarding food availability. Challenges such as the recent pandemic, which led to workforce and input shortages in agriculture, have made it difficult for many countries to maintain adequate food self-sufficiency (SSL). It is crucial to explore various farming methods to ensure that food remains available and affordable, especially in urban areas where over 55% of the population resides. Traditional agriculture faces issues like poor soil and excessive fertilizer use, which harm the environment. These factors threaten sustainable agriculture and food security, particularly in urban environments. Adopting sustainable soilless technology can enhance urban agriculture by providing a controlled environment for producing healthy food and addressing these challenges post-pandemic. This review, utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analys..... 162 hits |
| 1295 | 2024 Article | Islamic education in a globalised world: Insights from Malaysia Asif Mohiuddin Globalisation has transformed not just international commerce, communications, and economic relations in the second half of the 20th century, but it is also having a profound impact on religious education at the start of the third millennium. Malaysia is a part of the global community. Therefore, Malaysia is experiencing the spillover effects of the globalisation process. Islamic education is a key concept in the Islamic culture and is inextricably linked to the globalisation debate. This study endeavors to unravel the intricate ways in which globalisation has wrought a profound transformation in the realm of Islamic education in Malaysia. In a world where traditional religions have been relegated to the periphery, this study delves into the resilience and pertinence of Islamic education in the contemporary milieu. Embracing the forefront and dynamic realm of information and communication technologies (ICT) in Islamic education is an indispensable step that the Muslim community in Mala..... 106 hits |
| 1296 | 2024 Article | Employees’ entrepreneurial orientation in manufacturing firms: An empirical study Nallaluthan, Kesavan This study aims to examine the relationship between organizational characteristics, knowledge management enablers, learning orientation, and employee entrepreneurial orientation (EO) among manufacturing industry employees in Klang Valley, Malaysia. The theoretical model based on the Resource-Based Theory approach to employee EO was developed. To answer the research questions, seven hypotheses were formulated. Self-administered questionnaires were distributed to the manufacturing industry employees. A total of 386 manufacturing employees of all levels were involved in this study, making an overall 25.73% response rate. This study utilized the Partial Least Squares Structural Equation Modelling to establish the validity and reliability of the measurement model and test the relationships. The findings of the study showed that both organizational characteristics and knowledge management enablers have significant influences on employee EO. The results indicated that learning orientation has..... 192 hits |
| 1297 | 2024 Article | The impact of applying the servant leadership style among educators in educational institutes: A scoping review Mohamad Rohieszan Ramdan _ Leadership style is a critical concern in education amid technological shifts and paradigm changes. Despite extensive industry research, servant leadership remains underutilized in education, despite aligning with business education goals. This scoping review assesses the prevalence of servant leadership among educational leaders, offering insights into its feasibility, benefits, and challenges.
