Influence of Bamboo Cellulose Coating on the Flux Performance of Polyvinylidene Fluoride Hollow Fiber Membrane
No full textThis study showcases the characterization of a surface modified polyvinylidene fluoride (PVDF) hollow fiber membrane via Cellulose/PVDF coating. Scanning electron microscopy shows evidence of Cellulose/PVDF coating where surface roughness and coating lines with cracking is visible. The rough surface correlates with an improved pure water flux. However, the presence of surface cracks and higher cellulose loading results in decreased flux. Fourier transform infrared spectroscopy shows evidence of cellulose on the coated membrane. X-Ray diffraction revealed amorphous phase on the surface of the coated membrane, indicating that coated membrane has improved hydrophilic properties. The coated membrane samples have improved pure water flux performance up to 3 times the value from control (157.8864 L/m2/h/bar) for samples P01 (432.9142 L/m2/h/bar) and P02 (483.8453 L/m2/h/bar) which is th
Mechanical properties of sustainable freshwater marine sand mortar
No full textMarine sand has gained significant interest among researchers as a potential solution to the shortage of river sand for construction purposes. However, using marine sand as a fine aggregate in mortar has yielded contradictory results. To investigate the underlying reasons for this phenomenon, an experimental study was conducted to study the influence of marine sand with different characteristics on the mechanical performance of mortar. The shape and size of marine sand significantly impact its loose bulk density, voids and water absorption. The properties of marine sand mortar include workability, hardened density, flexural strength, and compressive strength. Beach marine sand, with its fine and uniform particles, requires higher water content, resulting in lower workability. This reduction in workability leads to decreased mechanical strength due to the increased voids within the mortar. However, marine sand’

THE INFLUENCE OF SOCIAL MEDIA USAGE ON BODY IMAGE PERCEPTION AND HEALTH AMONG UNIVERSITY STUDENTS: ROLE OF PEER INFLUENCE AS THE MODERATOR
No full textIdealised body image shared by peers on social media platforms has been associated with negative body image perception and a higher risk of disordered eating attitudes among university students. However, there is still a lack of
research studies on peer influence on social media usage on body image and health (disordered eating attitudes). This research aimed to investigate the influence of social media usage on body image perception and health (disordered eating attitudes), with the presence of peer influence as the
moderating factor. Correlational research was conducted (N=153) using simple random sampling. The results indicated that social media usage has a significant influence on body image perception and health (disordered eating attitudes). However, peer influence does not moderate the relationships
suggesting that social media usage still plays a huge role on body image perception and health (disordered eating attitudes) without the presence of peer influence
Internal Control Effectiveness in Malaysian Cooperatives: Insights from SelfOrganizing Maps and Artificial Neural Networks
No full textThe study aims to evaluate and visualize the effectiveness of internal control in Malaysian cooperatives. Adapting
the three categories of internal control objectives and the five internal control components in the internal control
integrated framework designed by COSO, the effectiveness of internal control is measured based on assessments conducted by the cooperative’s internal auditor or audit committee member, as Malaysian cooperatives are not required to provide material weakness statements in financial reporting. Survey data from 126 cooperatives generating Malaysian Ringgit (RM) 800,000.00 and above are clustered using the self-organizing map (SOM), a clustering technique based on artificial neural networks (ANNs). The analysis reveals four groups of internal control effectiveness in Malaysian cooperatives, visually demonstrating the association between internal control components and objectives. The results suggest an interrelated, albeit not straightforward, relationship between internal control components and objectives. The study emphasizes the importance of heightened attention to internal control within Malaysian cooperatives by responsible parties, including internal auditors, internal audit committees, cooperative management, cooperative boards, and the Malaysian Cooperative Society Commission (Mcsc). This paper represents one of the first attempts to assess internal control components and objectives in Malaysian cooperatives based on internal audit and audit committee assessments rather than relying on material weakness statements
A Narrative Study: Career Counselling Service among Person with Disabilities at Vocational Centre in Sarawak
No full textABSTRACT
Career development embodies a disposition of career maturity, requiring individuals to comprehend the developmental tasks and responsibilities they must undertake. Central to this journey is career counselling. This study focuses on Person with Disabilities (PWDs). The purpose of this narrative study is to highlight the significance of career counselling as the intervention for PWDs’ career development at vocational centre. Out of 637, 537 registered PWDs under Social Welfare Department, less than 12,000 of registered PWDs are employed as stated in Malaysian Employer Federation report on November 2023. Therefore, this study employs a narrative study with a focus on conducting semi-structured interviews.The participants in this study consist of two PWDs: one with physical disabilities and one with learning disabilities. Through this exploration, the study aims to shed light on the challenges faced by each PWDs in accessing career support and inform future interventions to promote PWDs vocational success and social inclusion. This study suggests that career counselling services are crucial for supporting the career development and self-concept of PWDs. This underscores the need for interventions aimed at improving access to such services and promoting the vocational success of PWDs.

A RETROSPECTIVE DOCUMENT REVIEW ON THE DISCHARGE OF ADOLESCENT PSYCHIATRIC PATIENTS IN A MALAYSIAN PSYCHIATRIC HOSPITAL
No full textAdolescents in Malaysia face a range of serious mental health challenges that often lead to repeated admissions to psychiatric wards. To ensure continuity of care and the effectiveness of long-term treatment, proper discharge intervention and comprehensive interventions prior to discharge are essential. This study aims to explore the current discharge interventions provided to adolescent psychiatric patients in a psychiatric hospital located in northern Peninsular Malaysia. Using a descriptive qualitative design, discharge records of 81 adolescent psychiatric patients admitted between 2021 and 2023 were reviewed. A data abstraction checklist was developed to systematically extract relevant information from the documents. Content analysis was conducted using the READ (Read, Extract, Analyse, Distil) approach to identify key patterns and gaps. Preliminary findings indicate an absence of standardised discharge intervention protocols. Notably, four critical components were frequently missing from the discharge process: integration of technology, linkage to community resources, collaboration with schools, and access to peer support. These findings underscore the urgent need for a structured and standardised discharge framework tailored to adolescents with psychiatric conditions. Strengthening discharge interventions could help reduce hospital readmissions and support sustained recovery within the community. Future research should delve deeper into specific psychiatric issues, particularly among adolescents with a history of suicide, to inform targeted discharge strategies.
