Creating a universal and supportive learning environment is essential for the holistic education development of visually impaired school children. However, inadequate infrastructure, limited access to specialized tools, and a shortage of skilled teachers may contribute to lower self-confidence and academic performance. This underscores the necessity for specific guidelines and recommendations to address an optimal classroom setting that is tailored to their visual needs. In this paper, a scoping review protocol is introduced, utilizing the framework proposed by Arksey and O'Malley (2005), to address the following research questions: 1) Is there any established standard classroom setting for visually impaired school children? 2) What recommendations or specific guidelines exist regarding the physical measurement, layout, lighting, contrast, and appropriate position for visually impaired school children? The scoping review explored four electronic databases: PubMed, Scopus Emerald Insight, and Web of Sciences. The outcomes from the scoping review will offer conceptual elucidation, synthesize existing theoretical and empirical understandings, and propose the optimal classroom settings tailored to the visual needs of visually impaired schoolchildren. This paper introduces the a-priori study protocol, which outlines the planned methodology for conducting the scoping review in detail. This protocol has been officially registered with the Open Science Framework (OSF) at the following link: http://osf.io/z2sdt.
Visually impaired schoolchildren require classrooms tailored to their visual abilities and needs, as outlined in existing literature detailing optimal modifications, recommendations, and guidelines. The study aims to review existing literature on classroom modifications for visually impaired schoolchildren, outlining recommendations for creating ideal classrooms within mainstream physical settings. After initial screening, 712 publications (698 from databases and registers, and 14 from other methods) were identified for detailed review, of which 17 were ultimately eligible for inclusion. Through a systematic review of PubMed, Scopus, and Web of Science databases, along with additional sources up to February 2024, this research analyzed articles published from 1999 to 2024. A qualitative, thematic analysis was conducted on the included articles. Criteria included peer-reviewed journals, theses, and conference papers focusing on classroom settings for visually impaired schoolchildren aged 7 to 18. Key questions addressed are: 1) What classroom settings suit the needs of visually impaired schoolchildren? 2) What recommendations are tailored to visually impaired schoolchildren to create a conducive classroom environment? Analysis of 7 journal articles and 10 other publications revealed two main themes: optimizing classroom configuration and enhancing visual comfort. Articles primarily focused on suggestions for classroom layout, particularly furnishing arrangement (41%, n = 7) and enhancing lighting conditions (41% n = 7). However, concerns were raised about standard furniture designs and the need for tailored seating arrangements to meet the visual demands of visually impaired schoolchildren. Conclusion: This review provides valuable insights into creating optimal classroom settings for visually impaired schoolchildren, ensuring equal learning opportunities in a supportive environment tailored to their needs.
Environmental impact assessment of glucose production from paddy milling waste, known as empty and partially filled paddy grain (EPFG) in Malaysia, was performed using life cycle assessment (LCA). Three scenarios were conducted based on system expansion of the process. The LCA was conducted using ReCiPe methodology at midpoint and endpoint levels. The results indicate that enzymatic hydrolysis phase is the hotspot in the conversion system due to enzyme production. In addition, the agriculture phase also contributed to negative impacts, especially towards climate change. An improved environmental load was observed in scenario 2 when all EPFG fractionation was utilised to replace fossil-based electricity. Sensitivity analysis showed an increase in glucose yield leads to reduced environmental impact. Thus, the LCA study suggests that the conversion process of EPFG could further benefit and improve the paddy industry waste management with low impact contribution to the environment compared to other feedstock used for glucose production.
Biochar production is an effective approach to managing abundant agricultural wastes. Pruning wastes from trimming the branches of trees such as carambola and mango, as well as coconut shells, are among the agricultural wastes that have reutilisation potential, which would simultaneously reduce the space required for disposal. In this study, the potential use of these wastes by converting them into biochar was investigated. The data presented in this study highlight the design of a pyrolysis system for a low-temperature slow pyrolysis process, as well as the characterisation data of the biochar produced using this system. The data collected included the elemental composition, porosity, as well as surface and adsorption characteristics of the biochar. These data indicate that the biochar produced had certain qualities that would enable its use for specific agricultural and industrial purposes. Meanwhile, the design indicated that it could facilitate small farms with specific outputs. In brief, these data can be used as references for developing a small-scale system for agricultural waste management using different types of crops.
Rice straw is one of the most abundant biomass wastes derived from rice cultivation activities. The current rice straw management practice during the wet (rainy) season in Malaysia involves the integration of straw into the soil. This practice offers both advantages and disadvantages to rice farmers and the environment. Straw integration may improve nutrient availability while concurrently causing high greenhouse gas (GHG) emissions due to the increase in soil carbon activity. In this work, the use of microbial substrate to enhance the degradation of straw was compared to an existing technique that used no additional inputs during soil integration. The data collected consisted of overall microbial enzyme production, soil organic carbon, soil nitrogen content, seasonal greenhouse gas emissions, plant characteristics, and crop yield. In brief, these data can be used as means of demonstrating the effects of improved straw degradation during the pre-season on the overall GHG emissions during the planting season.
