This study investigated the optical properties of neodymium nanoparticles (NPs) doped tellurite glass coated with graphene oxide (GO)/ reduced graphene oxide (rGO). Two series of glasses were prepared and coated using melt-quenching and spray-coating methods. The X-ray diffractograms proved the amorphous structure of the glass series. The presence of non-bridging oxygens in the glass network were proven via FTIR analysis. Meanwhile, the existence of neodymium nanoparticles in the tellurite glass network were confirmed using TEM analysis. FESEM and EDX analysis showed the morphologies of GO and rGO on the glass surface and their chemical elements, respectively. From UV-Vis spectroscopy analysis, the optical band gaps of ZBTNd (NPs)-GO and ZBTNd (NPs)-rGO were found in the range 2.355-2.998 eV and 2.770-3.125 eV, respectively. Meanwhile, the refractive index of ZBTNd (NPs)-GO and ZBTNd (NPs)-rGO were 2.041-2.194 and 2.339-2.657, respectively. Furthermore, the oxide ion polariz.....

Issues related to insider threat in organization have been actively debated over the years. Despite the probability, they have a higher rate of success, can go undetected, and therefore pose a much greater risk than external adversaries. Due to those circumstances, a protective and preventive measure becomes a pitch demand to prevent any harm caused by malicious insiders. A framework has been developed based on a survey conducted. There are five objectives posed in this research; (1) To identify factors that trigger/motivate insiders to attack an organization’s data (2) To determine the relationship between security behaviours and the appraisal process in Protection Motivation Theory (3) To determine the degrees of relevance of these identified reflective factors to Protection Motivation Theory (4) To develop a framework based on the result synthesized from data analysis (5) To verify the applicability of the proposed framework through expert judgement. The research adopt.....

Kajian ini bertujuan untuk membangunkan modul pembelajaran Rekatronik bagi topik reka betuk elektronik mata pelajaran Reka Bentuk dan Teknologi (RBT) dan keberkesanannya terhadap pencapaian pelajar tingkatan dua di sekolah menengah di Malaysia. Topik reka bentuk elektronik sukar dikuasai oleh pelajar dan kajian secara saintifik dan sistematik untuk membangunkan modul adalah perlu. Ini kerana kajian pembangunan modul pembelajaran bagi topik tersebut masih jarang dilakukan. Oleh yang demikian, modul pembelajaran Rekatronik berasaskan teori kontruktivisme dan pendekatan Pembelajaran Berasaskan Projek (PBP) dibangunkan. Kajian menggunakan reka bentuk kuasi-eksperimen untuk menentukan kesan modul pembelajaran manakala model Analysis, Design, Development, Implementation, and Evaluation (ADDIE) digunakan dalam proses pembangunannya. Dalam pembangunan modul, pendekatan ADDIE dengan pembahagian tiga fasa utama telah digunakan. Fasa pertama melibatkan analisis keperluan, fasa kedua a.....

The concept of derivation on rings is an old problem and plays a very important role in algebra,  analysis, geometry and physics. The concept of derivation was generalized in different directions  as centralizing derivation, Lie and Jordan derivations, (θ, φ)- derivation, generalized derivations  and reverse derivations. The main aim of this research is to generalize these concepts. Therefore,  the action of (θ, φ)- derivations on Lie and Jordan Ideals of prime rings with characteristic not  equal two will be investigated.  The next objective was to determine the commutativity of a prime  ring when the generalized derivation acting on the Jordan ideal of a prime ring. Furthermore, this  research will extend the centralizing derivations and reverse derivation on δ- ideal for δ- prime  rings. Finally, we extended the concepts of generalized reverse derivation and generalized reverse  (θ, φ)- derivation on a δ- prime and δ- semiprime rings. Some techniques and.....

Kajian ini bertujuan untuk mengenal pasti pengaruh kepimpinan dan emosi guru terhadap keberkesanan sekolah di Sekolah Menengah Harian (SMH) dan Sekolah Berprestasi Tinggi (SBT) di Selangor. Kajian ini juga bertujuan mengenal pasti tahap, perbezaan dan hubungan kepimpinan dan emosi guru terhadap keberkesanan sekolah. Kajian kuantitatif ini menggunakan kaedah tinjauan. Instrumen kajian diadaptasi daripada Teacher Leadership Self-Assessment, Teacher Emotion Scale dan School Effectiveness Questionnaire. Seramai 377 guru SMH dan 242 guru SBT di Selangor dipilih sebagai responden dengan menggunakan persampelan rawak bersistematik. Dapatan kajian menunjukkan dua dimensi kepimpinan guru iaitu membuat perubahan dan kemahiran pengajaran mempengaruhi secara signifikan terhadap emosi guru di SMH (Y=1.435 + 0.504X1 + 0.169X2) dan empat dimensi kepimpinan guru iaitu membuat perubahan, kesedaran diri, organisasi kendiri dan kemahiran mempengaruhi secara signifikan terhadap emosi guru di S.....

Learning English pronunciation is crucial for primary school pupils to enhance their communication skills, yet many struggle. This study evaluates the effectiveness of a natural language processing (NLP) tool in improving English pronunciation among primary school pupils by measuring motivation, confidence, and performance. Conducted in a primary school in Johor, the research used a randomised controlled trial (RCT) design with 30 Year 3 pupils, divided into two groups of 15 each: control and treatment. The English teacher assessed motivation, confidence, and performance using a rubric-based evaluation, with a Cronbach’s Alpha value of 0.932, indicating high reliability. Paired t-tests were conducted to determine if the differences in motivation, confidence, and performance between the two groups were statistically significant. For motivation, t-values ranged from -1.871 to -1.468 for the traditional method and -6.548 to -13.229 for the NLP method. For confidence, t-values ranged fro.....

Education plays a crucial role in shaping Malaysia's future development. However, access to higher education remains discriminatory, particularly for students from lower-income families, individuals with disabilities, and indigenous backgrounds, as they face challenges due to escalating living costs. The Malaysian government has initiated various education financial aid programmes to address this issue, encompassing scholarships, loans, and one-off aid. This initiative aligns with the broader goal of promoting inclusivity and ensuring all aspiring students have equal access to pursue their educational dreams. However, in many cases, some students apply for educational financial aid only to face rejection due to unmet requirements. Therefore, this paper proposes a responsive web-based system, namely EduFinBuddy, that will be able to identify the most suitable education financial aid based on student input. We begin the development process by extracting data from the targeted websites us.....

Online teaching and learning have caused many students and teachers with unprecedented challenges leading to a phenomenon known as the digital divide, which is the disparity between individuals who have access to Information and Communication Technologies (ICT) and those who do not. Therefore, this study aims to investigate the significant difference in facilitating conditions (network connection, technical issues, school infrastructure) and usage of Google Classroom for teachers in rural and urban teachers. In this study, 395 responses were collected from secondary school teachers through an online survey, that included demographic information and 22 survey items. Descriptive statistics and t-test analysis were used to analyze the data. Findings found that there are significant differences in technical issues and usage of Google Classroom for teachers in rural and urban schools. This research offers valuable insights for educational stakeholders especially the schools and government t.....
