    Carotenoid-rich red palm oil (RPO)-based snacks have been provided to children in impoverished communities to improve their vitamin A status. The non-availabilty of information on the acceptability of RPO-based snacks by Malaysian aborigines (Orang Asli) children forms the basis of this study.

    Existing mitigation strategies to reduce greenhouse gas (GHG) emissions are inadequate to reach the target emission reductions set in the Paris Agreement. Hence, the deployment of negative emission technologies (NETs) is imperative. Given that there are multiple available NETs that need to be evaluated based on multiple criteria, there is a need for a systematic method for ranking and prioritizing them. Furthermore, the uncertainty in estimating the techno-economic performance levels of NETs is a major challenge. In this work, an integrated model of fuzzy analytical hierarchy process (AHP) and interval-extended Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is proposed to address the multiple criteria, together with data uncertainties. The potential of NETs is assessed through the application of this hybrid decision model. Sensitivity analysis is also conducted to evaluate the robustness of the ranking generated. The result shows Bioenergy with Carbon Capture and Storage (BECCS) as the most optimal alternative for achieving negative emission goals since it performed robustly in the different criteria considered. Meanwhile, energy requirement emerged as the most preferred or critical criterion in the deployment of NETs based on the decision-maker. This paper renders a new research perspective for evaluating the viability of NETs and extends the domains of the fuzzy AHP and interval-extended TOPSIS hybrid model.

    Identification of appropriate clean technologies for industrial implementation requires systematic evaluation based on a set of criteria that normally reflect economic, technical, environmental and other aspects. Such multiple attribute decision-making (MADM) problems involve rating a finite set of alternatives with respect to multiple potentially conflicting criteria. Conventional MADM approaches often involve explicit trade-offs in between criteria based on the expert's or decision maker's priorities. In practice, many experts arrive at decisions based on their tacit knowledge. This paper presents a new induction approach, wherein the implicit preference rules that estimate the expert's thinking pathways can be induced. P-graph framework is applied to the induction approach as it adds the advantage of being able to determine both optimal and near-optimal solutions that best approximate the decision structure of an expert. The method elicits the knowledge of experts from their ranking of a small set of sample alternatives. Then, the information is processed to induce implicit rules which are subsequently used to rank new alternatives. Hence, the expert's preferences are approximated by the new rankings. The proposed induction approach is demonstrated in the case study on the ranking of Negative Emission Technologies (NETs) viability for industry implementation.

    INTRODUCTION: Burn injuries incur not just significant morbidity but also long-term psychosocial impact. This study aims to identify the clinico-demographics of children hospitalised for burns and factors associated with prolonged hospitalisation.

    MATERIALS AND METHODS: Written medical records of burn patients admitted to the Sultanah Aminah Hospital paediatric surgical ward, from January 2016 to December 2018, were retrospectively reviewed. Details on the patients' socio-demographic background, burn injuries, management and outcomes were recorded and analysed with logistic regression.

    RESULTS AND CONCLUSION: Of the 255 children included in the study, the majority were males (62.7%), children aged between 1 to 3 years (43.1%), and of the Malay ethnic group (83.1%). The commonest injury mechanism was scalds burns (81.2%). Staphylococcus aureus remained the commonest organism cultured from paediatric burn wounds. Most patients (66.4%) were hospitalised for less than 1 week. A significant number of patients experienced complications from their injuries. Multivariate analysis showed burns affecting total body surface area > 10% (adjusted OR, 13.45 [95% CI 6.25 - 28.96]; p = < 0.001) and non-scald burns (adjusted OR, 2.70 [95% CI 1.12 - 6.50]; p = 0.027) were the two main factors associated with prolonged hospitalisation of more than 1 week. These findings describing the epidemiology and outcomes of paediatric burn cases in a tertiary centre in Malaysia may inform future practice. More importantly, the information may contribute to the identification of at-risk populations and advise the development of effective prevention strategies to reduce the incidence and morbidity associated with paediatric burns in this region.
