    Millions of Muslims from all over the world perform Umrah and Hajj every year. There were 250,000 pilgrims from Malaysia in 2017, and the number is expected to grow by 20 percent in 2018. This projected increase will create a huge demand for Umrah and Hajj travel agencies’ services in Malaysia. At present, there are 328 Umrah and Hajj travel agencies registered under Malaysia’s Ministry of Tourism and Culture (MOTAC). However, the supposedly bright outlook maybe marred by undesirable consequences. Along with the increase in the number of Umrah and Hajj travel agencies, there also tends to be an increase in fraud Umrah packages offered by fake agents in Malaysia. Such incidents will cause sadness and anger in the victims and other involved parties. Umrah package fraud involving fake agents in Malaysia has attracted the attention of many including the public, the government, the private sector, even the media. Nevertheless, studies on correlation between Muslim travellers’ perception of the quality of service by Umrah travel agencies and their decision to purchase the Umrah package are scarce in Malaysia. Hence, this study investigated Muslim travellers’ perception of Umrah and Hajj travel agencies’ service quality and its influence on their decision to purchase the Umrah package, in an attempt to discover why some Muslim travellers fell into fake agents’ trap in Malaysia. A total of 319 Muslim respondents completed the questionnaire on service quality perception, specifically service quality elements and loyalty. The data obtained was examined using SPSS version 25 for descriptive and regression analysis. Umrah and Hajj travel agencies as well as relevant government agencies could use the findings of the study to assist with formulating plans and policies to improve the quality of service by Umrah and Hajj industry players and awareness among Muslim travellers on the importance of being able to identify bogus agencies. The limitations, implications andsuggestions for future research are also discussed.

    Teaching is a complex activity which consists not only of giving instructions but also promotion of learning. Different students have different preference for learning styles. Dental educators must therefore attempt to mix and match their methods of teaching to accommodate students with differing learning styles to provide an opportunity to maximize their learning. This paper aims to share the writer's experience and students' perceptions towards a different mode of teaching/learning method. The Jigsaw Classroom method was employed on University of Malaya's third-year dental students during their Water Fluoridation lecture. At the end of the session, students were asked to reflect upon the learning experience and to inscribe their feelings. Initially, students showed their resentment towards the new learning style but their resistance changed once they got into a group and started to learn from each other. In the reflective essay, most students expressed that learning through teaching and discussing as required in the Jigsaw method enhanced their understanding of the topic and they claimed that they were able to retain the information better. In this study, the Jigsaw method proved that learning in the lecture hall can be fun, educational and enriching.

    Previous studies have shown that stress on the vergence and accommodation systems, either artificially induced or naturally occurring, results in small misalignment of the visual axes, reduces binocular visual acuity and produces symptoms of ocular discomfort. This study examines the effect of artificially induced visual stress using ophthalmic prisms on three dimensional perception on 30 optometry students ages ranging from 19 to 29 years old. 6D base-in prisms, equally divided between the eyes (3D base-in each) was used to induce stress on the visual system producing misalignment of visual axes known as fixation disparity. The fixation disparity is quantified using near vision Mallett Unit and an enlarged scaled diagram. Stereoscopic perception was measured with the TNO test, with and without the presence of stress and the results was compared. Wilcoxon's matched pair ranked tests show statistically significant difference in the stereo thresholds of both conditions, p = 0.01 for advancing stereopsis and p = 0.01 for receding stereopsis, respectively. The study concludes that visual stress induced by prisms, produce misalignment of the visual axes and thus reduces three dimensional performance.

    In forest clearings of the Malaysian rainforest, chirping and trilling Mecopoda species often live in sympatry. We investigated whether a phenomenon known as stochastic resonance (SR) improved the ability of individuals to detect a low-frequent signal component typical of chirps when members of the heterospecific trilling species were simultaneously active. This phenomenon may explain the fact that the chirping species upholds entrainment to the conspecific song in the presence of the trill. Therefore, we evaluated the response probability of an ascending auditory neuron (TN-1) in individuals of the chirping Mecopoda species to triple-pulsed 2, 8 and 20 kHz signals that were broadcast 1 dB below the hearing threshold while increasing the intensity of either white noise or a typical triller song. Our results demonstrate the existence of SR over a rather broad range of signal-to-noise ratios (SNRs) of input signals when periodic 2 kHz and 20 kHz signals were presented at the same time as white noise. Using the chirp-specific 2 kHz signal as a stimulus, the maximum TN-1 response probability frequently exceeded the 50% threshold if the trill was broadcast simultaneously. Playback of an 8 kHz signal, a common frequency band component of the trill, yielded a similar result. Nevertheless, using the trill as a masker, the signal-related TN-1 spiking probability was rather variable. The variability on an individual level resulted from correlations between the phase relationship of the signal and syllables of the trill. For the first time, these results demonstrate the existence of SR in acoustically-communicating insects and suggest that the calling song of heterospecifics may facilitate the detection of a subthreshold signal component in certain situations. The results of the simulation of sound propagation in a computer model suggest a wide range of sender-receiver distances in which the triller can help to improve the detection of subthreshold signals in the chirping species.

    This study was designed to examine the relationships between problem-solving skills, hardiness, and perceived stress and to test the moderating role of hardiness in the relationship between problem-solving skills and perceived stress among 500 undergraduates from Malaysian public universities. The analyses showed that undergraduates with poor problem-solving confidence, external personal control of emotion, and approach-avoidance style were more likely to report perceived stress. Hardiness moderated the relationships between problem-solving skills and perceived stress. These findings reinforce the importance of moderating role of hardiness as an influencing factor that explains how problem-solving skills affect perceived stress among undergraduates.

    Background: Dispensing separation (DS) is a critical policy change that will reduce medical costs, improve population health and increase the quality of healthcare in Malaysia. This study aims to determine the awareness and perception of the public regarding the DS methods.

    Methods: This cross-sectional study uses a pre-validated, self-administered questionnaire, which has been administered to 200 residents in Jitra, Kedah, Malaysia. Descriptive and inferential statistics have been used to analyse the data.

    Results: Females formed 64.0% of the participants, with Malay being the dominant ethnic group (n = 167, 83.5%); 77.5% of the participants reported they were aware of the role of pharmacists in the healthcare system. However, 35.0% of the participants reported having never heard the term 'dispensing separation' in any mainstream media in Malaysia, whereas 73.5% of the participants reported that a pharmacist was more reliable than a physician in providing medicines once the diagnosis had been made and 77.5% of them acknowledged that pharmacists were experts in the field of medication. There was a significant association between the participant's awareness and the agreement on perceptions toward the implementation of the DS (P < 0.05).

    Conclusion: Awareness of the implementation of DS among residents in Jitra is still low. However, there is strong evidence of public support and the benefits of DS in Malaysia.

    Aim: This study evaluates perception toward facial appearance in dentofacial deformity and the need for orthognathic surgery among the public with and without dental backgrounds. Materials and Methods: A questionnaire consisting of 12 facial photographs of cases with dentofacial deformity or malocclusion in varying severity was used. A hundred individuals were selected to answer the questionnaire. The perception of facial appearance (FAS), treatment need score (TNS), and knowledge regarding dentofacial deformity were used for the evaluation. Results: Significant differences were found between dental and non-dental when the respondents' knowledge in all the questionnaire items ([Formula: see text].05) was assessed. However, no significant difference was found in the mean of FAS and TNS in all the presented cases (normal, borderline, severe). Pearson correlation between perceived FAS and TNS was statistically negative for severe and normal cases, whereby a decrease in FAS for severe cases showed an increase in TNS, and an increase in FAS for normal cases showed a decrease in TNS. Conclusion: Respondents with dental background had sound knowledge of dentofacial deformity. A poorly attractive respondent with dentofacial deformity showed a greater need for orthognathic surgery.

    BACKGROUND: The influence of scaler tip design on root surface roughness, tooth substance loss and patients' pain perception is investigated.

    METHODS: This article was divided into the following parts: Part 1 Surface roughness and substance loss: an in vitro study, which involves intact extracted teeth sectioned and treated using a piezoelectric ultrasonic device (PM200 EMS Piezon, Switzerland) with a conventional scaler tip (FS-407) and a Perio Slim (PS) scaler tip (Perio Slim DS-016A). All sectioned samples for tooth surface roughness (n = 20) and tooth substance loss (n = 46) analyses were measured and compared using a 3D surface texture analyser and scanning electron microscope (SEM) respectively, at baseline and following scaling. Part 2 Pain Perception: a clinical study, which was a split mouth study design including 30 participants with gingivitis and/or mild chronic periodontitis; treated with supra-gingival scaling from teeth #13 to #23. Subjects were randomised to group A or group B. Group A was treated first with PS scaler tips, whereas group B was treated first with conventional scaler tips. Pain perception was recorded using the visual analogue scale (VAS).

    RESULTS: In vitro study: both scaler tips caused significant reduction in root substance roughness after scaling (p  0.05) was observed. The PS scaler tip caused statistically significantly less root substance loss (p

    Pre-pregnancy Clinic (PPC) services is one the plausible efforts towards achieving the Millennium Development Goals. However, various issues still need to be addressed for improvement of the services. Considering this view, an attempt was made to explore the barriers, strength and weakness of current practice of pre-pregnancy clinic services in Sarawak, since the programme has been implemented in this state from the year 2011. This cross-sectional study was conducted at nine selected health care facilities throughout Sarawak. A multistage sampling procedure was adapted to select the health care facilities. An unstructured open-ended questionnaire was administered to get the in-depth perceived views and current practice of pre-pregnancy clinic services. A total of 322 health care providers from nine selected health care facilities gave their feedback. In the present paper, a qualitative analysis was done for the openended questions to get in-depth views of barriers, strength and weakness of pre-pregnancy clinic services. The results of the study were narrated in textual form and a thematic analysis was done manually. The identified themes for perceived barriers to the provision of pre-pregnancy care were perception, attitude and acceptance of PPC services, socio-economic issues, services and client factors. The perceived weaknesses of the services are listed under two main themes: working environment and service factors, while, the strength of services produced three thematic areas which are preparation for pregnancy, prevention of mortality and morbidity and comprehensive services. Though prepregnancy services are beneficial for society wellbeing, various issues still need to be considered for the improvement of the quality of services. Lack of awareness, no ministerial guidelines or Standard Operating Procedures (SOP) and knowledge pertaining to the services were few of the main areas which need to be pondered upon. Promotional activities and campaigns should be geared up ensuring availability the services to the general population.

    Background: Falls are a significant incident among older adults affecting one in every three individuals aged 65 and over. Fall risk increases with age and other factors, namely instability. Recent studies on the use of fall detection devices in the Malaysian community are scarce, despite the necessity to use them. Therefore, this study aimed to investigate the association between the prevalence of falls with instability. This study also presents a survey that explores older adults' perceptions and expectations toward fall detection devices. Methods: A cross-sectional survey was conducted involving 336 community-dwelling older adults aged 50 years and older; based on randomly selected participants. Data were analyzed using quantitative descriptive analysis. Chi-square test was conducted to investigate the associations between self-reported falls with instability, demographic and walking characteristics. Additionally, older adults' perceptions and expectations concerning the use of fall detection devices in their daily lives were explored. Results: The prevalence of falls was 28.9%, where one-quarter of older adults fell at least once in the past 6 months. Participants aged 70 years and older have a higher fall percentage than other groups. The prevalence of falls was significantly associated with instability, age, and walking characteristics. Around 70% of the participants reported having instability issues, of which over half of them fell at least once within 6 months. Almost 65% of the participants have a definite interest in using a fall detection device. Survey results revealed that the most expected features for a fall detection device include: user-friendly, followed by affordably priced, and accurate. Conclusions: The prevalence of falls in community-dwelling older adults is significantly associated with instability. Positive perceptions and informative expectations will be used to develop an enhanced fall detection incorporating balance monitoring system. Our findings demonstrate the need to extend the fall detection device features aiming for fall prevention intervention.

    The deficiency in the human auditory system of individuals suffering from sensorineural hearing loss (SNHL) is known to be associated with the difficulty in detecting of various speech phonological features that are frequently related to speech perception. This study investigated the effects of speech articulation features on the amplitude and latency of cortical auditory evoked potential (CAEP) components. The speech articulation features included the placing contrast and voicing contrast. 12 Malay subjects with normal hearing and 12 Malay subjects with SNHL were recruited for the study. The CAEPs response recorded at higher amplitude with longer latency when stimulated by voicing contrast cues compared to that of the placing contrast. Subjects with SNHL elicited greater amplitude with prolonged latencies in the majority of the CAEP components in both speech stimuli. The existence of different frequency spectral and time-varying acoustic cues of the speech stimuli was reflected by the CAEPs response strength and timing. We anticipate that the CAEPs responses could equip audiologist and clinicians with useful knowledge, concerning the potential deprivation experience by hearing impaired individuals, in auditory passive perception. This would help to determine what type of speech stimuli that might be useful in measuring speech perception abilities, especially in Malay Malaysian ethic group, for choosing a better rehabilitation program, since no such study conducted for evaluating speech perception among Malaysian clinical population.

    The effectiveness of children's oral health education (OHE) is determined by the appropriateness of the educational materials used, which can influence their attitude towards oral health. However, there is a lack of studies exploring the benefits of OHE materials from the perspective of schoolchildren. This study aimed to explore schoolchildren's opinions on the newly developed ToothPoly board game as an OHE tool. A qualitative approach using focus group discussions (FGDs) was conducted among 44 schoolchildren aged 12 years old from a public school in Malaysia. Convenience sampling was employed to recruit the schoolchildren. The ToothPoly board game was playtested and FGDs were conducted after the playtesting session ended. Data collection and analyses were performed concurrently until data saturation was reached. The data were transcribed and coded using Atlas.Ti software version 9.1.3 followed by the framework method analysis. Mixed opinions were observed among the schoolchildren with a majority expressing favourable opinions on the advantages of the ToothPoly board game as an OHE tool. Five themes emerged from the advantages aspect, i.e., fun and enjoyable, promote focus, attention and oral health-related learning, attractive board game features, and enhance peer interaction. Meanwhile, two themes emerged that were related to the disadvantages of the board game, i.e., "competition with online games and media" and "not practical for a large group activity". The findings showed that the ToothPoly board game was perceived as a useful, interactive, and enjoyable tool to learn about oral health in small groups. The findings of the study highlight the importance of tailoring OHE activities to fulfil the needs of specific target groups to ensure its acceptance and future success.

    One of the major concerns in any pharmacological treatment is the patients' adherence to medication. However, different types of ocular dosage forms might result in different response and compliance from the patients. This study investigated and compared public willingness on different types of dosage forms available for ocular treatment. The study also evaluated their willingness on new approach for the treatment based on their knowledge, attitude, and perception. This study was conducted between October and December 2017 through a set of questionnaires applied to 90 respondents between the age of 18 and 60 years who lived in Muar and Kuantan, Malaysia. The results were analyzed using SPSS software version 22.0 including inferential and descriptive statistics. There was no significant difference in the knowledge level between all age groups towards different types of dosage forms available; eye drops (P = 0.09), eye ointment (P = 0.252), medicated contact lens (P = 0.05), ocular mini-tablets (P = 0.06), and ocular inserts (P = 0.075). There is a variation of results among the public towards different types of dosage forms with their willingness to try conventional and novel approach. Eye drops show the highest willingness followed by eye ointment (less willingness). However, most of them showed no willingness towards medicated contact lens, ocular mini-tablets, and ocular insert. This research hopes to provide an overview on the development process of new formulation and dosage forms based on the patients' willingness level in an attempt to increase patient compliance.

    A poor understanding of Ebola Virus Disease (EVD) among Health Care Professionals (HCPs) may put our lives at risk. We aimed to assess the awareness, knowledge, attitudes, perceptions, beliefs of HCPs towards Ebola at Gondar University Hospital (GUH) in Northwest Ethiopia. We conducted a hospital based, cross-sectional survey among 245 randomly selected HCPs working at GUH from August-October, 2015. A validated, self-administered questionnaire was used to collect the data. We calculated descriptive statistics with P<0.05 being statistically significant. Of the 245 participants, 211 (86.1%) completed the study. The majority had heard about EVD and used news media (62%) as a source of information. Still, many were afraid of getting EVD (56.4%; P=0.001). A significant number of HCPs thought EVD can cause paralysis like polio (45%) and can be treated with antibiotics (28.4%). In addition, 46.4% of the HCPs felt anger or fear towards Ebola infected patients (P=0.006). We identified poor knowledge and negative incorrect beliefs among doctors and allied health professionals. There is a need for intensive training for all HCPs reduce EVD risk.

    OBJECTIVE: To identify the relationship between knowledge, attitude and perception regarding environmental tobacco smoke (ETS) and smoking among Malaysian adolescents living in states with complete or partial smoke-free legislation (SFL).
    METHODS: A total of 898 respondents aged 13-14 years were randomly selected from 21 secondary schools. The Malay version of the modified Global Youth Tobacco Survey questionnaire was used. Hierarchical logistic regression was performed in examining predictors of smoking attempt among adolescents.
    RESULTS: Participants exposed to ETS >5 h/day were more likely to have smoked compared to those exposed to ETS <1 h/day (OR 4.1, 95%CI 1.03-16.0). Living in a state with partial SFL was associated with a two-fold increase in self-reported smoking attempts (OR 1.95, 95%CI 1.10-3.43) compared to living in a state with complete SFL. Negative attitudes and perceptions towards smoking and ETS exposure were linked to lower smoking attempts in states with complete SFL.
    CONCLUSIONS: Adolescents with limited ETS exposure who lived in a state with complete SFL were less likely to attempt smoking compared to those exposed more regularly to ETS and living in a state with partial SFL. Preventing adolescents from becoming smokers is the key to reducing national prevalence rates in smoking. There is a need to implement comprehensive smoke-free legislation nationally across Malaysia.

    This study investigated the perception and awareness of risk among adult participants in Bangladesh about Coronavirus Disease 2019 (COVID-19). During the lockdown era in Bangladesh at two different time points, from 26-31 March 2020 (early lockdown) and 11-16 May 2020 (late lockdown), two self-administered online surveys were conducted on 1005 respondents (322 and 683 participants, respectively) via social media. To examine risk perception and knowledge-related factors towards COVID-19, univariate and multiple linear regression models were employed. Scores of mean knowledge (8.4 vs. 8.1, p = 0.022) and perception of risk (11.2 vs. 10.6, p < 0.001) differed significantly between early and late lockdown. There was a significant decrease in perceived risk scores for contracting SARS-Cov-2 [β = -0.85, 95%CI: -1.31, -0.39], while knowledge about SARS-Cov-2 decreased insignificantly [β = -0.22, 95%CI: -0.46, 0.03] in late lockdown compared with early lockdown period. Self-quarantine was a common factor linked to increased perceived risks and knowledge of SARS-Cov-2 during the lockdown period. Any effort to increase public awareness and comprehension of SARS-Cov-2 in Bangladesh will then offer preference to males, who did not practice self-quarantine and are less worried about the propagation of this kind of virus.

    BACKGROUND: This preliminary finding from a qualitative study examined the process of self-efficacy for the development of physical activity during myocardial infarction (MI) after recovery. A combination of healthy behaviors, including physical activity is the secondary prevention recommended to reduce the risk of recurrent MI. This study aims to understand how self-efficacy for physical activity is developed in a patient after MI by examining their perceptions and personal adherence to physical activity.

    DESIGN AND METHODS: This was a qualitative study and data was collected through semi-structured in-depth recorded phone interviews with eight Malay male participants. They were screened using a questionnaire and participants that met the inclusion criteria were interviewed, and were admitted to National Heart Centre, Malaysia between January to June 2019 diagnosed with MI. The data collected were analysed using NVivo 12 software and thematic analysis was applied.

    RESULTS: Four preliminary themes emerged from the study: 1) beliefs in physical activity; 2) healthy lifestyle: new normal or same old habit; 3) factors determining participation in pa; and 4) physical activity adherence strategies.

    CONCLUSIONS: The results of the studies showed that participants understand the need to maintain physical activity, which helps to maintain a healthy life after MI and prevent recurrent infarction. Strategies for developing self-efficacy for physical activity were also discussed. The need to understand that maintaining physical activity as well as adopting a new normal of healthy habit after MI is crucial in order to maintain the health and prevent recurrence of MI.

    1. Obesity is a metabolic disease of pandemic proportions largely arising from positive energy balance, a consequence of sedentary lifestyle, conditioned by environmental and genetic factors. Several central and peripheral neurohumoral factors (the major ones being the anorectic adipokines leptin and adiponecin and the orexigenic gut hormone ghrelin) acting on the anorectic (pro-opiomelanocortin and cocaine- and amphetamine-regulated transcript) and orexigenic (neuropeptide Y and agouti gene-related protein) neurons regulate energy balance. These neurons, mainly in the arcuate nucleus of the hypothalamus, project to parts of the brain modulating functions such as wakefulness, autonomic function and learning. A tilt in the anorectic-orexigenic balance, perhaps determined genetically, leads to obesity. 2. Excess fat deposition requires space, created by adipocyte (hypertrophy and hyperplasia) and extracellular matrix (ECM) remodelling. This process is regulated by several factors, including several adipocyte-derived Matrix metalloproteinases and the adipokine cathepsin, which degrades fibronectin, a key ECM protein. Excess fat, also deposited in visceral organs, generates chronic low-grade inflammation that eventually triggers insulin resistance and the associated comorbidities of metabolic syndrome (hypertension, atherosclerosis, dyslipidaemia and diabetes mellitus). 3. The perivascular adipose tissue (PVAT) has conventionally been considered non-physiological structural tissue, but has recently been shown to serve a paracrine function, including the release of adipose-derived relaxant and contractile factors, akin to the role of the vascular endothelium. Thus, PVAT regulates vascular function in vivo and in vitro, contributing to the cardiovascular pathophysiology of the metabolic syndrome. Defining the mechanism of PVAT regulation of vascular reactivity requires more and better controlled investigations than currently seen in the literature.
