The internal fixation plate of bone fractures by using polylactic acid (PLA) has attracted the attention of many researchers, as it is biodegradable and biocompatible to the human body. However, its brittleness has led to implant fracture. On the contrary, polypropylene carbonate (PPC), which is also biodegradable and biocompatible, has an excellent elongation at break. The purpose of this paper is to compare the PLA fixation plate with the new fixation plate made up of PLA/PPC blends by using finite element analysis (FEA).

The mandible bone from CT data set and fixation plate was designed by using the MIMICS, Amira and Solidworks softwares. Abaqus software was used for FEA of PLA/PPC fixation plate applied on the fractured mandible bone. A model of mandibular bone with a fracture in the body was subjected to incisor load. The analysis was run to determine the von Mises stress, elongation of the fixation plate and the displacement of the fractured gap of PLA/PPC blends fixation plate.

The von Mises stress predicted that all the blend compositions were safe to be used as a fixation plate since the stress values were less than the yield strength. In addition, the stress value of the fixation plate was gradually decreased up to 20 percent when the amount of PPC increased to 30 percent. This indicates that the stress shielding effect was successfully reduced. The elongation of the fixation plate was gradually increased from 11.54 to 12.55 µm as the amount of PPC in the blends increased from 0 to 30 percent, thereby illustrating that the flexibility of the fixation plate was improved by the addition of PPC. Finally, the measured displacement of the fractured gap for all compositions of PLA/PPC blends fixation plate is less than 150 µm, which proves the likely success of fracture fixation by using the PLA/PPC blends.

An optimum solution of PLA/PPC blends and another new material such as compatibilizer need to be introduced in the blends in order to improve the performance of PLA/PPC blends as a new material for a fixation plate. Besides, by using the same method of producing PLA/PPC blends, longer durations for in vitro degradation of PLA/PPC blends are essential to further understand the degradation behavior of the blends applied in the human body. Finally, it is also important to further test the mechanical strength of PLA/PPC blends during the degradation period to know the current strength of the implant in the healing process of the bone.

PLA fixation plate and screw can commercially be used in CMF surgery since they reduce cost because of the elimination of secondary surgery to remove the fixation plate and screw after the healing process.

It is hoped that the advantages of this research will ensure the market of PLA product to continue expanding in medical application.

This study is one of the alternative ways for the biomedical researchers to improve the elongation break of PLA. Currently, many researchers focus on polymeric materials such as PLA, poly(glycolic) acid and polydioxanone blends, which were extensively being used in CMF surgery. However, the work on PLA/PPC blends to be used as one of the materials for the CMF fixation plate is very limited, if any. PPC, the proposed material for this research, will improve the mechanical performance of PLA fixation plate and screw to become more sustainable and flexible when applied on human mandible bone.

This study aims to investigate the monitoring role of ownership structure (OWS) on real earnings management (REM) practices; previous studies primarily examined the effect of OWS on accrual-based earnings management.

The sample of this study is 490 companies listed on the Malaysian Stock Exchange during the period 2013–2016 (1,960 company-year observations). The regression of a feasible generalized least square was used for data analysis. The authors use three regression models ordinary least squares, panel-corrected standard errors and Driscoll–Kraay standard errors to corroborate the findings and also examine alternative REM measures.

Analysis of the data shows that family, foreign and institutional ownership has a positive link with the quality of financial reporting and, to a large extent, is capable of alleviating REM. The findings also indicate that some form of OWS significantly affects REM, corroborating existing theories on corporate governance (CG) and the perspectives of practitioners.

The evidence concerns the significant role played by the OWS in reducing REM activities. The findings are useful in support of regulatory activities, particularly in the design of policies to regulate the OWS. The results may also provide useful insights to inform other policymakers, investors, shareholders and researchers about the active role of family, foreign and institutional investors in monitoring Malaysia's public listed companies (PLCs) to strengthen CG practices. This also leads to less REM and enhances the quality of financial reporting.

To the authors' knowledge, this work is pioneering research from a developing country, specifically from Malaysia, to investigate the manner in which all possible OWSs influence REM. More importantly, the study recommends that regulators and researchers do not envisage OWS as a holistic phenomenon.

The purpose of this paper is to identify the strain of oyster mushroom (OM) Pleurotus sapidus cultivated in a local (commercial) farm, and to generate a total quality index (TQI) on the strain using different modified atmosphere packaging (MAP) gas mixtures.

A phylogenetic tree was constructed using the MEGA software to identify the specific strain of P. sapidus grown in a local farm. The effects of MAP on fresh fruiting bodies of the identified strain were determined under three conditions: high carbon dioxide packaging (HCP: 20 per cent CO₂, 15 per cent O₂), low carbon dioxide packaging (LCP: 2 per cent CO₂, 30 per cent O₂) and high nitrogen packaging (HNP: 85 per cent N₂, 15 per cent O₂). All samples were stored at 4 ^oC for up to ten days, and subjected to total phenolic content (TPC), colour retention (CR) and sensory analysis. Quality parameters such as chewiness and odour were used to obtain the TQI.

From the phylogenetic analysis, a new strain (P. sapidus strain QDR) with 99 per cent similarity to P. sapidus was identified. Among the three MAP treatments, HCP recorded the highest TPC (2.85 mg GAE/g) and CR (60.36) after ten days, although only its CR was significantly different (p<0.05) from the control. Feedback from 30 sensory panellists indicated that both HCP and LCP were generally more effective in retaining the colour–odour of OM. The optimum TQI for HCP was obtained based on the observed parameters, which is useful for the large-scale packaging of OM.

Scientific evidence has revealed that packaging trend for commercially grown OM affects consumer’s acceptance.

The purpose of this paper is to build a relationship between the quantitative and structural indicators of maqashid sharia studies produced from bibliometric analysis and the conceptual discussion developed through a thorough review of selected key literature.

The study uses bibliometric analysis, collecting information drawn from 219 articles published in 68 journals during the period of 2006–2022. This study uses VOSviewer, RStudio, Microsoft Excel, and an examination of research time periods using the Scopus database to illustrate the citation analysis and keyword map. It is also strengthened by content analysis of selected studies.

The main research theme found in this study is the application of maqashid sharia in Islamic banks, with Islamic banks and Islamic finance among the most frequently used keywords. Meanwhile, the geographical spread of maqashid sharia research has reflected its universal acceptance, as it has spread across both Muslim-dominant and non-Muslim-dominant countries. Besides, maqashid sharia is found to be an extremely important subject for ensuring the ethical dimension of Islamic finance products and services, a more inclusive human development index, and contributing to the international agenda of Sustainable Development Goals. Lastly, future research is expected to broaden it into a multi-dimensional horizon, with several recommendations offered to enrich the understanding of maqashid sharia.

The findings of this study can be beneficial to multiple stakeholders in Islamic finance industry, including the management of Islamic banks, who can enhance the values of maqashid sharia in designing their products/services, and the regulators, who can formulate regulatory frameworks which are reflective of maqashid sharia principles.

This study will assist future scholars in this field to formulate and design exciting research ideas and models to address the deficiencies found in the current implementation of maqashid sharia within Islamic finance industry.

The primary contribution of this study is to provide comprehensive review and discussion of selected significant literature on maqashid sharia and give direction for future research. In addition, this study also extends and incorporates the results of bibliometrics using the recent maqashid sharia studies published at the end of 2022.

This paper aims to fill the noticeably fragmented zakat literature repertoire by empirically exploring stakeholders’ views toward zakat management performance issues based on a selected zakat institution (ZI) operating on a corporatized platform with corporate administrative style.

A quantitative approach using a questionnaire survey distributed to Muslims in the State which ZI is operating was adopted. A total of 448 usable responses are used in the analysis covering descriptive and mean difference.

The results indicate that managerial reform configuration in terms of corporatization has been viewed positively by stakeholders, translated into a comforting agreement score toward ZI’s improved management performance (collection, disbursement and reporting). Such perceptions are, however, observably sensitive to demographic factors of gender and employment type. The survey also document evidence that the corporatization exercise itself had improved respondents’ confidence toward ZI being the zakat administrator in the State.

The research contributes to the public policy debate with respect to corporatized ZI’s management performance from the stakeholders’ perspective. The results are arguably informative at various levels, forming a basis for reality check and policy inputs for various stakeholders, including (but not limited to) the ZI itself, zakat payers and asnafs, particularly in designing relevant and necessary administrative strategies and relevant policy formulation in addressing the performance and accountability issues in ZIs.

The halal industry has been growing in recent years, seeing an increasing demand for halal products from both Muslim and non-Muslim consumers and acknowledging that halal is a universal concept accepted by both Muslim and non-Muslim societies. Service-related providers, such as logistics, could influence the demand for halal products by consumers. This paper aims to investigate the factors that influence consumers' willingness to pay (WTP) for halal logistics among young non-Muslim adults.

A set of survey questions were distributed to young non-Muslim adults and 280 questionnaires were analysed.

The results indicate that three independent variables had a direct relationship and significant influence on the WTP for halal logistics among non-Muslim consumers. These variables are concern on halal, knowledge about halal and perception of halal logistics. Meanwhile, the awareness of halal logistics significantly influenced the consumers' WTP for halal logistics, provided that it was mediated by the perception of halal logistics.

Given the gap in research on halal logistics and WTP, this paper presents a consolidated examination of this subject, particularly the WTP of young non-Muslim adults. Furthermore, by including the perception of halal logistics as a mediator, this study leverages the halal logistics knowledge to a new level, thus deepening the understanding of this topic and contributing additional knowledge. This study also presents some opportunities for future empirical research.

Studies have shown that managing household solid waste from low-cost housing in urban and sub-urban communities is challenging, especially in developing countries and COVID-19 era. Previous research proved that the fourth industrial revolution (4IR) technologies could be engaged to improve urban public services such as household solid waste. Thus, the study investigated 4IR role in improving low-cost housing solid waste management (LCHSWM) in the COVID-19 era across Malaysia's cities.

The researchers selected four Malaysian cities (Pulau Pinang, Kuala Lumpur, Kuching and Putrajaya) to achieve the study's objectives via a qualitative research design. The study engaged forty experts through semi-structured virtual interviews. A thematic approach was used to analyse the collected data.

Findings identified initial high implementation and maintenance costs, unwillingness to accept change, inadequate knowledge and skilled personnel to manage the operation, amongst others, as the perceived challenges facing 4IR technologies in managing low-cost housing solid waste across Malaysian cities in the COVID-19 era. Also, the study proffered measures to improve 4IR technologies usage.

This paper is limited to the perceived contributory challenges and proffered measures to improve 4IR technologies usage in managing LCHSW across Malaysian cities in the COVID-19 era.

Proffered measures will stir policymakers and the political class (city councils) to start thinking of an all-inclusive approach to addressing the issue of LCHSW in the 21st century. As part of the practical implications, the possible outcome might enhance collaboration between the public and private sectors to better service delivery to mitigate environmental degradation.

As revealed in the review, there is a paucity of literature regarding digital technology's roles in mitigating LCHSW across Malaysian cities in the COVID-19 era.

This study aims to assess the household food insecurity in Malaysia during the initial phase of the movement control order (MCO) to provide insights into the prevalence and predictors of food insecurity in this context.

The research used an online cross-sectional survey between March 28 and April 28, 2020. The study collected data from the Radimer/Cornell Hunger Scale and a food insecurity instrument. Analytical tools included chi-square and logistic regression models.

Of the 411 participating households, 54.3% were food-secure, while 45.7% experienced varying food insecurity. Among these, 29.9% reported mild hunger-associated food insecurity, 8.5% experienced individual food insecurity and 7.3% reported child hunger. The study identified predictors for food insecurity, including household income, as those with total income of < RM 2,300 had 13 times greater odds (odds ratio [OR] 13.8; confidence interval [CI] 5.9–32.1; p < 0.001) than those with income of RM 5,600, marital status as divorced (OR 4.4; 95% CI 1.0–19.9; p-value = 0.05) or married (OR 1.04; 95% CI 0.52–2.1) compared to those who are single. Self-employed respondents had three times greater odds of living in a household experiencing food insecurity (OR 3.58; 95% CI 1.6–7.7; p-value = 0.001) than those in the private sector (OR 1.48; 95% CI 0.85–2.61) or experiencing job loss (OR 1.39; 95% CI 0.62–3.1) compared with those who reported being in full-time government employment.

This study acknowledged limitations, such as not considering various dimensions of food insecurity, such as coping strategies, nutritional support, diet quality and well-being, due to the complexity of the issue.

The study underscores the importance of targeted support for vulnerable groups and fostering collaborative efforts to address household food insecurity during crises like the MCOs.

The research offers insights into how to address household food insecurity and its impact on society.

It identifies predictors, quantifies increased odds and emphasizes the necessity of targeted policies and collaborative approaches for fostering resilient recovery and promoting well-being in vulnerable populations.

This study aims to identify the enabling factors for Building Information Modeling (BIM) adoption in Vietnamese construction enterprises and uncover their interrelationships. This will help stakeholders focus on controlling and allocating resources (time, personnel, and costs) appropriately to adopt BIM and differentiate themselves from fierce competition in the architectural, engineering, construction and operations (AECO) industry.

This study first identifies and evaluates 32 enabling factors for applying BIM in the Vietnamese construction industry according to the TOE extended framework. Afterwards, a hybrid questionnaire survey using a convenient sampling method is conducted to capture stakeholders' views. The exploratory factor analysis (EFA) and the partial least squares structural equation modelling (PLS-SEM) technique are then applied to identify the constructs of the enabling factors and their interrelationships.

The study extracts six constructs that could have a significant impact on the adoption of BIM in construction enterprises, namely: technical feasibility (TF), human resources and management (HRM), company business vision (CBV), political environment (PE), economic viability (EV), and legal aspects (LA). Based on eleven proposed hypotheses, the analysis results confirm nine hypotheses and show that the HRM, TF, and CBV have the strongest effects on managers in evaluating the factors for BIM.

The results of the study fill the gap in knowledge by discovering the interrelationships among the enabling factors for BIM adoption in construction enterprises. The results might support the construction enterprises and their stakeholders in increasing the application of BIM, and digital transformation in construction industry.
