ABSTRACT
Relationship satisfaction (RS) is one of the major components of mental health that is often ignored due to cultural reasons. Moreover, numerous studies had indicated that when individuals have insecure attachment styles (insecurity in loving someone else), they would never develop any RS with anyone, including friends, spouses, parents, children, and relatives. The coronavirus disease 2019 (COVID-19) pandemic had triggered different social patterns among individuals all over the world, and studies during the pandemic indicated the significance of some factors such as the sense of mattering and perceived life satisfaction (LS) to the mental health of the general adults. Our references led us to hypothesize that interpersonal mattering (IM) significantly predicted RS, mediated by LS, under the condition of low secure attachment style (SAS). Randomly selected 405 adults from Kuala Lumpur and Selangor, Malaysia, were financially compensated to complete the scales of IM, satisfaction with life, SAS section of measure of attachment style (MOAS), and RS index. The results indicated that the mediation of LS on the link between mattering and RS was only significant when the level of SAS is at the low and moderate levels. Further implications, limitations, and suggestions are discussed. © 2022, Intelektual Pustaka Media Utama. All rights reserved.
ABSTRACT
Coronavirus disease (COVID-19) has infected many people worldwide. As the probability of being infected by the virus increases with an increase in the number of people gathered in an indoor space, methods for reducing its spread indoors are urgently required. In this study, a classroom with 25 students was considered as an indoor space, and an attempt was made to devise a method to reduce the concentration of the viruses generated indoors more effectively. Through numerical analysis, the age of air inside the classroom was compared and analyzed when both the air cleaner and natural ventilation were used. The age of air varied locally in the classroom depending on the position of the air cleaner, confirming its importance in effectively removing particles possibly containing viruses generated indoors. When the air cleaner flow rate was doubled, the age of air was almost halved, implying that the concentration of the particles including viruses generated indoors can be reduced efficiently by increasing the air cleaner flow rate. Natural ventilation performed by completely opening the windows and doors of the classroom reduced the age of air. It was observed that the operation of the air cleaner along with open windows and doors of the classroom reduced the concentration of the particles including viruses generated indoors more effectively. More specifically, when both natural ventilation and air cleaner were applied, the age of air decreased by almost 50% compared with the only air cleaner case and by about 22% compared with the only natural ventilation case.
