University students are known to have different sleeping schedules. Students’ sleep difficulties will affect their health and their performances in studies. Sleep hygiene is a collection of healthy sleep habits that can improve one’s ability to fall asleep and stay asleep. It is considered to be imperative to treat sleep disturbance especially among university students. The aim of this study is to examine the sleep beliefs among the students of UiTM Sabah based on gender and academic performance. This study was conducted on Diploma students between March and July 2018. The respondents were randomly selected from Diploma students of all faculties in UiTM Sabah: Accounting, Business Management, Public Administration, Science, Planting Industry Management, Hotel Management, and Tourism Management. This paper is based on the Sleep Belief Scale questionnaire to assess the sleep hygiene awareness. Questionnaires were distributed using online survey. Findings of this study were analyzed using SPSS statistical software. The result of findings showed that the Sleep Incompatible Behaviours (drinking coffee, taking sleep medication, smoking before sleep) is the highest contributor of the students’ sleep hygiene and therefore it affects the sleep quality. While the Sleep Wake Cycle Behaviours (going to bed & waking up always at the same hour, going to bed two hours earlier than the habitual hour) and Thoughts and Attitude to Sleep (over thinking before sleep, trying to fall asleep without having a sleep sensation)also contributed to the sleep hygiene of the students but not as high as the Sleep Incompatible Behaviours. Based on the results of the findings, the counseling department of UiTM Sabah may organise an education program to create awareness among students about the intervention and prevention strategies as well as the incorrect beliefs about sleep.
Numerous routing protocols for mobile ad hoc networks (MANETs) have been designed in process information delivery from a source node to a destination node. In this paper, the Taguchi’s design of experiment (TDE) has been applied to investigate the performance of Destination Sequence Distance Vector (DSDV) routing protocol in MANETs. The effects of network parameters namely terrain sizes, node speeds, network sizes, transmission ranges, transmission rates, pause times and the number of maximum connections on packet delivery ratio and routing overhead in medium scale ad hoc networks have been done through simulation experiments. Through this study, we can rank these factors that may affect packet delivery ratio and routing overhead. The response performance was analyzed based on signal-to-noise ratio and analysis of variance (ANOVA). The results revealed that the transmission range was the most influential factor on the packet delivery ratio, followed by terrain size and transmission rate. The network size had the greatest effect on routing overhead, followed by the transmission range.
