Web-based learning environment based on students’ needs

Traditional learning needs to be improved since it does not involve active learning among students. Therefore, in the twenty-first century, the development of internet technology in the learning environment has become the main needs of each student. One of the learning environments to meet the needs of the teaching and learning process is a web-based learning environment. This study aims to identify the characteristics of a webbased learning environment that supports students’ learning needs. The study involved 542 students from fifteen faculties in a public higher education institution in Malaysia. A quantitative method was used to collect the data via a questionnaire survey by randomly. The findings indicate that the characteristics of a web-based learning environment that support students’ needs in the process of learning are online discussion forum, lecture notes, assignments, portfolio, and chat. In conclusion, the students overwhelmingly agreed that online discussion forum is the highest requirement because the tool can provide a space for students and teachers to share knowledge and experiences related to teaching and learning

An acceleration simulation method for power law priority traffic

A method for accelerated simulation for simulated self-similar processes is proposed. This technique simplifies the simulation model and improves the efficiency by using excess packets instead of packet-by-packet source traffic for a FIFO and non-FIFO buffer scheduler. In this research is focusing on developing an equivalent model of the conventional packet buffer that can produce an output analysis (which in this case will be the steady state probability) much faster. This acceleration simulation method is a further development of the Traffic Aggregation technique, which had previously been applied to FIFO buffers only and applies the Generalized Ballot Theorem to calculate the waiting time for the low priority traffic (combined with prior work on traffic aggregation). This hybrid method is shown to provide a significant reduction in the process time, while maintaining queuing behavior in the buffer that is highly accurate when compared to results from a conventional simulatio

Diverse Accounting Standards on Disclosures of Islamic Financial Transactions: Prospects and Challenges of Narrowing Gaps

Purpose: Since International Financial Reporting Standards (IFRS) are not primarily meant for the accounting needs of Islamic banks, the Accounting and Auditing Organisation for Islamic Financial Institutions (AAOIFI) was established to develop specific accounting standards for Shari’ah compliance. The purpose of this paper is to assess the de jure harmonisation between the disclosure requirements of the IFRS-based Malaysian Accounting Standards (MAS) and those of the AAOIFI. Design/methodology/approach: Using Malaysia as a case study, the paper examines the extent of the de jure congruence between the IFRS-based MAS and AAOIFI’s Financial Accounting Standard No 1 (FAS1), which is considered to be one of the key disclosure standards for Islamic banks. We employ leximetrics and content analysis to analyse these accounting standards and the additional guidelines introduced by the Malaysian Accounting Standards Board (MASB) and the Central Bank of Malaysia (Bank Negara Malaysia, BNM) to identify the gaps between different tiers of MAS and FAS1. Findings: The study finds that de jure congruence between the IFRS-based MAS and AAOIFI standards has improved through the introduction of additional accounting guidelines by both the MASB and the banking regulator, BNM. However, some gaps remain between the two standards. These gaps may be difficult to completely eliminate due to differences in the fundamental principles underlying the development of both standards. Originality/value: While some studies have explored the de facto congruence between AAOIFI accounting standards and others, this paper is the first, to the best of the authors’ knowledge, to examine the de jure congruence between those standards with the IFRS-based MAS

Permeability and tensile strength of concrete with Arabic gum biopolymer

The use of materials of vegetal origin is increasingly being promoted in many industries due to their cost effectiveness and the rising sensitivity to environmental protection and sustainability. Arabic Gum Biopolymer (AGB) is a wild plant byproduct that is abundantly found in Sudan and is also produced in other African countries. It has long been used in various industries. However, its utilization is very limited in the construction sector although there appears to be a significant potential for use of AGB in the building industry. As an example, there is evidence that AGB may be an effective additive to concrete mixes that would improve fresh and hardened concrete properties. The aim of the present work is to provide further experimental evidence on the improvement that can be achieved in the physical and mechanical properties of hardened concrete when AGB is added to the mixture. The experimental results show a significant reduction in permeability for an optimum percentage of AGB and an increase in flexural and tensile strength and in the elastic modulus

Radiation protection literacy and its associated factors among healthcare workers in Negeri Sembilan

Background: Ionizing radiation can be an occupational hazard that need protection when in the form of particle which can produce biological changes to cells, tissues or organs. About 19.7% of worldwide average radiation dose is due to the medical use of radiation. In Malaysia, about 700,000 X-ray examinations were performed in 2014. The objective of this study is to assess the level and predictors for radiation protection literacy among healthcare workers in Negeri Sembilan. Materials and Methods: A cross-sectional study was conducted in health facilities in Negeri Sembilan from April 2018 to June 2018 among 151 healthcare workers. Respondents were selected based on their workplace using proportionate stratified random sampling method and data was obtained using validated self-administered questionnaire that focused on knowledge, attitude and practices on radiation protection. Data were analyzed using IBM SPSS version 23.0. Result: 52.3% of respondents had high knowledge, 80.8% had positive attitude and 56.3 % had good practice on radiation protection. Significant predictors for high knowledge were the use of radiation hazard monitoring device and being a radiation worker meanwhile for positive attitude was received medical surveillance. Significant predictors for good practice were the use of radiation hazard monitoring, being a radiation worker, being a health professional and being a health associate professional. Conclusion: Attitude on radiation protection among healthcare workers in Negeri Sembilan was still positive despite knowledge and practice was marginal. Future radiation protection awareness programme, education and training should be strengthen in order to improve radiation protection literacy among healthcare worker in Negeri Sembilan
