Abstract

In 2020, the COVID-19 pandemic has had a huge impact on the education system in Malaysia, especially at higher education level. A number of public or private universities have carried out online learning classes due to the Covid-19 pandemic and avoid the spread of the virus among university students. Face to-face learning can not be implemented because the learning efficiency in class management decreased. Thus, this study discussed the integration of wireless sensors within the classroom, focusing on improvement of ventilation system and learning efficiency in classroom design. As a result, the goals of this research are to identify the types of wireless sensors that can be used to improve the ventilation system in classroom design, to identify the mechanisms of wireless sensors that can be used to improve the ventilation system in classroom design, and to propose design guidelines for using wireless sensors to improve the ventilation system and learning efficiency in classroom design. Reviews on related topics such as wireless sensor technology and smart classroom will be made via online searching articles and journals. Acquisition of primary data and secondary data will be done via case study of smart classroom from relevant articles and journals.

Abstract

Sick building syndrome (SBS) is a condition that afflicts occupants of a building, typically a workplace, and is linked to time spent in the building(Thach et al., 2019). The precise cause for SBS is still unknown. However, there are a few possibilities that is believed to be the cause of SBS such as poor ventilation, bad lighting design, presence of mold, fungus and formaldehydes which is usually found in wood furniture. This research paper focuses on the furniture factor of SBS. Certain material and finishes used in furniture production are harmful to the users as it has the potential to emit chemical substances from the wood composite products(Jeon et al., 2011) which could affect the indoor air quality. Furniture production may not sound harmful, but if the processes were observed in detail, we can see animal exploitations along the progress. Adhesives used to join the furniture may have substances that are derived from animals. The objective of this research is to study the chemical component in an animal-based adhesive and plant-based adhesive in wood furniture that is commonly used in lobby or lounge area (sofa, coffee table, etc.). With the chemical components identified, it is used to see how it contributes to the Sick Building Syndrome and which adhesives will be a better option for furniture production. This research also aims to compare animal-based and plant-based adhesives in terms of quality and cost. This research uses the qualitative method in which we look at past research first-hand observations, interviews, data, etc. The outcome by the end of this research will achieve all research objectives and suggest a better adhesive in wood furniture production whether it is animal-based or plant-based adhesives that has the least effect to SBS. This research can be beneficial to all furniture companies that are finding an alternative for a safer and greener choice of adhesive in wood furniture production. This research can also be a guideline to help improve the quality in furniture production and reduce the risk of SBS.
