The main objective of the survey was to investigate the relationship between Professional Learning Community (PLC) and Teacher Attitudes Toward Change (TATC). By employing disproportionate stratified sampling, a total of 1004 school teachers from 64 Day Secondary Schools completed the questionnaires with valid data. The results demonstrated that, (i) there was a significant, positive and mediocre relationship between PLC and TATC; (ii) Principals' Commitment and Support, Collegial Understanding and Trust, External Support System, Structural Support and Shared Norms and Vision of PLC were correlated significantly to TATC and (iii) Collaborative Learning, Collective Inquiry and Reflective Dialogue were not associated significantly with TATC. As a whole, the development of PLC in schools has significant relationship with TATC that influences teachers' behavioural intention and ultimately determine their attitudes to embrace school change. The study not only provides empirical evidence tha.....

Good public transportation that can offer a pleasant peaceful and relaxing environment is necessary for improving people's interest in using it. Thermal comfort is determined in this study by measuring the air velocity and temperature of the air-conditioning from the outlet. Both data are taken using a digital anemometer and thermocouple with three replications for reproducibility. For data collection, a 10-row shuttle bus was held immobile for 30 minutes. According to the data, outlet 5 received the highest air velocity and the lowest temperature, at 9.12 ms-1 and 13.6 C, respectively. It was also discovered that the design of the air-conditioning ducting impacts the reachability of cooled air to the farthest outlets, adversely affecting the target cool temperature and passenger comfortability. It is suggested that in order to promote the attractiveness of public transportation, the inner bus compartment and air-conditioning system in hot countries should prioritise thermal comfort. 2.....

The objective of the current study was to develop a mobile application to aid problems faced by students in the subject of Home Science. Previous studies have discovered that that many students struggle to understand topics related to nutrient content, nutritional practices, the digestive and absorption systems. Therefore, a mobile application known as MyNutrient was developed in accordance to the content of the standards of Food Needs, Nutrients, and Functions found in the Food and Nutrition topic in the Home Science subject. The development process of MyNutrient was based on the ADDIE model. This study later employed a qualitative method. An interview was conducted with three experts with expertise in the Home Science field and a good understanding of the design and evaluation of instructional materials. The findings reveal that MyNutrient consists of content that is aligned with the Standard Curriculum and Assessment Document (DSKP). It also helps users, especially students, in stre.....

Online  distance  learning,  on  the  one  side,  makes  the  learning  process  more  efficient  and  flexible.  However,  on  the  other  hand,  it  produces  learning  loss  within  a  particular  educational  period  and  makes  students  less  enthusiastic  about  building  a  collaborative  attitude.  In  general,  online  learning  platform providers have provided support for collaboration activity features, but in reality, they have not been able to support effective interaction. Experts believe that using the Personal Learning Environment (PLE) as an IT tool in the learning process can help create an effective online collaboration environment. This study found that PLE was proven to increase collaborative activities in online learning significantly.  The  reflection  feature  is  the  type  of  PLE  that  has  the  most  significant influence on creating a good collaboration environment. The research also   found   th.....

This research measured the interaction effect among learning styles, gender, and types of mind maps on writing performance at IAIN Palangka Raya, Indonesia. The design applied a posttest quasi-experiment using a 3x2x2 analysis of variance. The study involved EFL participants comprising three groups based on learning styles (x1): auditory, visual, kinaesthetic; gender (x2): male and female; model of mind map (x3): digital mind map/DMM and paper mind map/PMM. The total participants were 30 L2 learners. Result revealed that a significant interaction among learning styles (x1), gender (x2), and types of mind map (x3) exists on the learners writing performance at the MS 129.14, F(2.30)=3.64, p=0.04. However, no interaction effect between learning styles and gender F(2.29)=0,21, p=0.81, eta 0.02; between learning styles and types of mind map F(2.29)=0.85, p=0.44, eta 0.09; between gender and types of mind map F(1.29)=0.49, p=0.49, eta 0.03 on writing performance. The main effect also confirm.....

The Randic index R(G) of a graph G is the sum of the weights (dudv)− 12 of all edges uv in G, where du denotes the degree of vertex u. Du and Zhou [On Randic indices of trees, unicyclic graphs, and bicyclic graphs, Int. J. Quantum Chem. 111 (2011), 2760–2770] determined the n-vertex unicyclic graphs with the third maximum for n ≥ 5, the fourth maximum for n ≥ 7 and the fifth maximum for n ≥ 8. Recently, Li et al. [The Randic indices of trees, unicyclic graphs and bicyclic graphs, Ars Comb. 127 (2016), 409–419] obtained the n-vertex unicyclic graphs with the sixth maximum and the seventh maximum for n ≥ 9 and the eighth maximum for n ≥ 10. In this paper, we characterize the n-vertex unicyclic graphs with the ninth maximum, the tenth maximum, the eleventh maximum, the twelfth maximum and the thirteenth maximum of Randic values...

Graphene-based nanomaterials have significant potential to be used as coating materials for glass performance. In this work, reduced graphene oxide (rGO)-coated tellurite glass was synthesized via melt-quenching and low-cost spray coating techniques for improving the optical properties in the glassy matrix. The structural properties investigated using X-Ray Diffraction (XRD) confirmed the structural arrangement of an amorphous nature phase meanwhile, Scanning Electron Microscopy (SEM) analysis proved the morphological structure images of rGO onto the tellurite glass surface. The refractive index value of rGO-coated glass was found higher in the range of 2.402 - 2.775 due to the graphene-based effects. The optical bandgap energy value of rGO-coated glass was improved from 1.913 - 2.980 eV which correlated to the changes in rGO absorption characteristics. The Urbach energy showed a high number of defects in absorption with the presence of rGO structures. By virtue of improved optical pro.....

The genus Knema Lour. is distributed mainly in Southeast Asian and widely used in folk medicine for treating diseases such as jaundice, chronic fever, and inflammation. The chemical composition, acetylcholinesterase inhibition, and molecular docking studies of essential oil from Knema hookeriana Warb. were investigated in this study. The essential oil was achieved through hydrodistillation and was characterised using gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The acetylcholinesterase inhibitory activity was evaluated using Ellman method while molecular docking studies were carried out using Autodock v.4.3.2. The results revealed that the essential oil examined consisted mainly of ?-caryophyllene (26.2%), germacrene D (12.5%), ?-cadinene (9.2%), germacrene B (8.8%) and bicyclogermacrene (5.5%). The essential oil showed acetylcholinesterase activity with IC50 value of 70.5 g/mL. The enzyme-ligand molecular docking study showed that ?-caryophyllene and ?.....

The Movement Control Order (MCO) was implemented in Malaysia on 18 March 2020. The MCO has changed peoples lifestyle to some extent because they have been advised to work from home. Due to this situation, the Malaysian Ministry of Education (MOE) implemented online learning methods throughout the MCO period to prevent the spread of the Covid-19 virus. Therefore, all schools have implemented online teaching and learning with the instructions of the MOE as a new norm to ensure that learning sessions are not delayed. The purpose of this study was to determine the level and factors of effectiveness of online learning for secondary school students studying economics subjects during the Covid-19 pandemic. This study used a quantitative research design employing a questionnaire as data collection instrument. The results show that the effectiveness of online learning for economics students is at a high level. The results of the survey illustrate that most students use mobile phones and laptops.....
