    Equity theory suggests that perceiving equity leads to better relationship outcomes than perceiving inequity. However, cultural and relationship differences in tolerance for inequity have been found, suggesting that those from more individualistic cultures may have less tolerance for inequity with friends than those from more collectivistic cultures, with the latter group discriminating more clearly in their reactions to friends and strangers. In our first study, Kadazandusun (N=282) and Australian (N=255) participants evaluated their actual reciprocity in social support with a close friend. In our second study, 103 South East Asians and 128 Australians were randomly assigned to respond to a scenario presenting equity or inequity (underbenefit or overbenefit) with either a close friend or stranger. Study 1 found that participants from both cultures reported reduced desires for future interaction, positive feelings and closeness when they experienced under-benefit as compared to over-benefit or equity. In Study 2, participants from both cultures also reported reduced desires for future interaction, positive feelings and trust when there was inequity and reported a more negative reaction to a stranger than a close friend. These findings are consistent with equity theory and support its cross-cultural applicability.

    Euthanasia is one of the most controversial topics of the 21st century after cloning and genetic engineering. Has this issue arisen now due to changes in attitude and perception on life of the modem society? This project was undertaken to study the opinions of 2 selected groups of people and secondly, to highlight the legal, ethical and religious controversies on euthanasia. Two groups comprising medical undergraduates and medical personnel were given a questionnaire pertaining 10 his/her opinion and altitude towards euthanasia. The second part of the project was conducted via interviews. The overall opinion from 399 respondents showed that 67.91% are against the practice of euthanasia. Religion is a powerful force against it as Malaysians in general are God-fearing people. There should be proper guidelines explaining how a doctor should respond to patients or family members of patients who request for euthanasia to be performed. It is not legal in Malaysia, but the court has the inherent power to permit it should a particular case have substantial reasoning and evidence. In conclusion, the level of awareness on euthanasia among medical staff and undergraduates is satisfactory. However, most of them do not approve euthanasia in Malaysia.

    PURPOSE: This study aims to discover the perception of persons with disabilities (PWDs) towards facilities management (FM) service quality at hospital buildings in Malaysia.

    DESIGN/METHODOLOGY/APPROACH: A questionnaire survey was conducted with 99 respondents in selected hospitals in Selangor, Malaysia.

    FINDINGS: This study aims to discover the perception of PWDs towards FM service quality, and it has found a gap for improvement. The area that requires the highest attention includes the importance of (1) assurance on accessibility despite maintenance activity being conducted (2) criticality of facilities maintenance itself, (3) assurance on comfort and safety, (4) reliable medium to ask for assistance or giving feedback, (5) signage that is clearly seen and easily understood and (6) staff responsiveness.

    RESEARCH LIMITATIONS/IMPLICATIONS: This instrument is validated by PWDs under the physical disability category only, specifically in the hospital context. Future research is recommended to identify the FM service quality aspect for different categories of disability (sensory, mental or intellectual impairment).

    PRACTICAL IMPLICATIONS: The findings provide evidence for FM to consider PWDs' perceptions in FM strategy development. Even FM provides a healthcare support system. FM service quality partly reflects healthcare service quality.

    SOCIAL IMPLICATIONS: Accommodating the need of PWDs through the improvement of FM service quality aspect will partly fulfil the right of PWDs for equality of access to healthcare.

    ORIGINALITY/VALUE: This SERVQUAL tools can be improvised and used to measure the perception of PWDs on FM service quality systematically and holistically. Understanding the service quality aspect is important for a facility manager to precisely measure and prioritise what is truly important to the building users with special needs and try to accommodate this need in the management activity.

    Artificial intelligence (AI) is an innovative tool with the potential to impact medical physicists' clinical practices, research, and the profession. The relevance of AI and its impact on the clinical practice and routine of professionals in medical physics were evaluated by medical physicists and researchers in this field. An online survey questionnaire was designed for distribution to professionals and students in medical physics around the world. In addition to demographics questions, we surveyed opinions on the role of AI in medical physicists' practices, the possibility of AI threatening/disrupting the medical physicists' practices and career, the need for medical physicists to acquire knowledge on AI, and the need for teaching AI in postgraduate medical physics programmes. The level of knowledge of medical physicists on AI was also consulted. A total of 1019 respondents from 94 countries participated. More than 85% of the respondents agreed that AI would play an essential role in medical physicists' practices. AI should be taught in the postgraduate medical physics programmes, and that more applications such as quality control (QC), treatment planning would be performed by AI. Half of the respondents thought AI would not threaten/disrupt the medical physicists' practices. AI knowledge was mainly acquired through self-taught and work-related activities. Nonetheless, many (40%) reported that they have no skill in AI. The general perception of medical physicists was that AI is here to stay, influencing our practices. Medical physicists should be prepared with education and training for this new reality.

    INTRODUCTION: The incorporation of serious games in higher education has shown improvement in student engagement and motivation to learn. Research that explores local pharmacy student preferences of gamification aspects of serious games is scarce. Therefore, this study was conducted to investigate local pharmacy student experience, preference, and perceptions of gaming and game-based learning.

    METHODS: A cross-sectional study was conducted by distributing self-administered questionnaires among pharmacy students in Malaysia. Descriptive statistics, the Mann-Whitney test, the Kruskal-Wallis test, and the Spearman's correlation test were used for analysis.

    RESULTS: A total of 328 pharmacy students enrolled in this study, and 84.1% (n = 276) had video game experience. Students usually played video games using mobile phones (n = 231, 70%). Pharmacy students showed positive perceptions regarding serious games with a mean score of 3.69. However, limited awareness and knowledge of serious games was observed among pharmacy students. The most preferred game genres were role-playing and strategy (n = 174, 53%). Pharmacy students also preferred playing a cooperative game style (n = 113, 34.5%) with scores as a reward system (n = 204, 62.6%). Over three quarters (n = 292, 89.3%) wanted to see the results of the assessment after the game.

    CONCLUSIONS: This research provided information on serious games preferences of local pharmacy students. Further study should evaluate the acceptance and effectiveness of the implementation of serious games among pharmacy students in Malaysia.

    BACKGROUND: Simultaneous electroencephalography (EEG) and functional magnetic resonance image (fMRI) acquisitions provide better insight into brain dynamics. Some artefacts due to simultaneous acquisition pose a threat to the quality of the data. One such problematic artefact is the ballistocardiogram (BCG) artefact.

    METHODS: We developed a hybrid algorithm that combines features of empirical mode decomposition (EMD) with principal component analysis (PCA) to reduce the BCG artefact. The algorithm does not require extra electrocardiogram (ECG) or electrooculogram (EOG) recordings to extract the BCG artefact.

    RESULTS: The method was tested with both simulated and real EEG data of 11 participants. From the simulated data, the similarity index between the extracted BCG and the simulated BCG showed the effectiveness of the proposed method in BCG removal. On the other hand, real data were recorded with two conditions, i.e. resting state (eyes closed dataset) and task influenced (event-related potentials (ERPs) dataset). Using qualitative (visual inspection) and quantitative (similarity index, improved normalized power spectrum (INPS) ratio, power spectrum, sample entropy (SE)) evaluation parameters, the assessment results showed that the proposed method can efficiently reduce the BCG artefact while preserving the neuronal signals.

    COMPARISON WITH EXISTING METHODS: Compared with conventional methods, namely, average artefact subtraction (AAS), optimal basis set (OBS) and combined independent component analysis and principal component analysis (ICA-PCA), the statistical analyses of the results showed that the proposed method has better performance, and the differences were significant for all quantitative parameters except for the power and sample entropy.

    CONCLUSIONS: The proposed method does not require any reference signal, prior information or assumption to extract the BCG artefact. It will be very useful in circumstances where the reference signal is not available.

    The present study was conducted to investigate the effects of brown rice (BR) powder addition on the proximate composition, total dietary fibre content and acceptability of some selected Malaysian traditional rice-based local kuih. Two types of kuih samples, namely Kuih Lompang (KL) and Kuih Talam Pandan (KTP) were prepared at the levels of either 0%, 10%, 20% or 30%. The kuih samples were analyzed for nutritional composition and sensory acceptance. There was significant increase in total dietary fibre content (from 2.64 g/100 g to 3.15 g/100 g) and protein content (from 2.36% to 2.51%) with the incorporation of 90% BR powder in the KL formulation. The moisture (from 36.79% to 36.83%), ash (from 1.11% to 1.21%) and fat (from 8.51% to 8.73%) content were not significantly affected for all percentages of BR powder addition. For KTP, the addition of BR powder at the level of 90% significantly increased the total dietary fibre (from 2.77 g/100 g to 3.45 g/100 g), fat (from 5.73% to 6.95%) and moisture (from 64.10% to 64.12%) content as compared to the control (0%). However, the protein content was not significantly affected (from 3.41% to 3.59%). On the other hand, there was no significant difference for all sensory attributes of KL formulated with 30-90% of BR powder as compared to the control (0%). The sensory score of KTP added with 30-90% BR powder received significantly lower sensory score compared to the control sample (0%) for appearance, colour, firmness, adhesiveness, chewiness, taste and overall acceptance attributes. In summary, sensory evaluation showed that all BR-incorporated KL were acceptable, while only 30% addition of BR powder in KTP was acceptable. Thus, BR powder is potentially used in improving the nutritional composition of KL. However, further study is needed to improve palatability aspect of KTP formulated with BR powder.

    Previous experiments investigating visual search have shown that distractors that are semantically related to a search target can capture attention and slow the search process. In two experiments, we examine if distractors exactly matching, or semantically related to, search-irrelevant information held in working memory (WM) can also influence visual search while ruling out potential effects of color similarity. Participants first viewed and memorized an image of an everyday object, then they determined if a target item was present or absent in a two-object search array. On exact-match trials, the memorized object appeared as a distractor; on semantic-match trials, an object semantically related to the memorized object appeared as a distractor. Both exact-match and semantic-match distractors slowed search when the target was present in the search array. Our findings extend previous findings by demonstrating WM-driven attentional guidance by complex objects rather than simple features. The results also suggest that visual search can be influenced by distractors sharing only semantic features with a search-irrelevant, but active, WM representation.

    The resurgence of bed bugs is a global phenomenon, but until now reports on bed bug infestations in Indonesia are rare. The success of bed bug control is affected by people's knowledge and awareness. Stigma against bed bugs in Indonesia discourages the public from reporting infestations and therefore knowledge of their impact on public health is scarce. Herein, this study investigates the public's perception, attitudes, and knowledge on bed bug-related issues in several major cities in Indonesia through an online survey. Despite low case reports, three in five respondents (n = 600) have encountered bed bugs at least once; mostly in their homes (74.1%). Approximately half of the respondents correctly identified bed bugs, whereas mites were often misidentified for bed bugs (26.3%). Bite marks were not a useful indicator for detecting bed bugs. We found age, gender, and level of education affects the public's perception toward various bed bug-related issues. Regarding bed bug treatment, above 50% respondents are unaware of the availability of bed bug-specific insecticidal products and are unwilling to pay pest management professionals to control infestation. This study provides the first overview of the public's awareness and perception of bed bug infestations in some major cities of Indonesia, which can be useful for designing public health policies for bed bug management. The reported data represents the perspectives of online users, most likely from metropolitan regions. A bigger monitoring program encompassing pest professionals and hospitality businesses would give a more thorough overview of the bed bug impact in Indonesia.

    Objective. To examine pharmacy students' performance on and perceptions regarding the use of an interactive online tool for practicing to take objective structured clinical examinations (OSCEs).Methods. The Monash OSCE Virtual Experience (MOVE), an online module consisting of 20 pharmacy case scenarios with virtual patients, was piloted with final-year pharmacy students at Monash University campuses in Australia and Malaysia. A mixed methods approach that included reviewing user attempts and comparing grades, collecting student-administered questionnaires, and holding focus groups was used to examine students' perception and performance.Results. More than 99% of all students attempted at least one online case scenario in preparation for their final in-person OSCE, and 81% attempted all 20 scenarios two or more times. Ninety percent of students at the Malaysia campus and 70% of students at the Australia campus reported that MOVE was a helpful study tool for their OSCE preparation. However, a raw comparison of user attempts and OSCE grades did not find a direct correlation between online module attempts and assessment grades. Self-administered questionnaire and focus group results indicated that MOVE prepared students for targeted and time-restricted history-taking and problem-solving skills. Overall, students perceived MOVE to be a useful learning tool and a less overwhelming learning experience than were face-to-face sessions. Nevertheless, students still preferred face-to-face OSCE practice with simulated patients over online practice with virtual patients.Conclusion. The Monash OSCE Virtual Experience was perceived by our students as a flexible and useful online learning aid in preparing for their final-year OSCE However, there was no direct correlation between online practice attempts and students' exam grades.

    BACKGROUND: The incidence and aftermath of the COVID-19 pandemic brought about a drastic change in health professional education around the world. Traditional classrooms made way for online classrooms in order to ensure that learning continued in a safe and secure environment. However, how well health professional students perceived and accepted these changes have not been fully gauged yet. Therefore, this study aims to evaluate the perception of health professional students about their new educational climate.

    METHODS: A modified and validated Dundee Ready Education Environment Measure (DREEM) questionnaire was used to collect data regarding student perception of their educational environment.

    RESULTS: The mean DREEM scores for three time periods were in the accepted positive range of 101 to 150 indicating that most of the students perceived the changes positively. The results indicated that most students preferred blended learning over online learning or face-to-face learning alone. Areas where students were unsatisfied with their learning environment that need improvement were identified by poor item-wise scores.

    CONCLUSION: Strategic remedial measures for these concerns need to be developed to improve the quality of education received by the students. However, the results of our study indicated that most of the students were able to adapt positively to the new education environment due to the change in the circumstances during COVID.

    BACKGROUND: Role of information source, perceived benefits and risks, and destination image has significantly been examined in travel and tourism literature; however, in medical tourism it is yet to be examined thoroughly. The concept discussed in this article is drawn form well established models in tourism literature.

    METHODS: The purpose of this research was to identify the source of information, travel benefits and perceived risks related to movement of international patients and develop a conceptual model based on well-established theory. Thorough database search (Science Direct, utmj.org, nih.gov, nchu.edu.tw, palgrave-journals, medretreat, Biomedcentral) was performed to fulfill the objectives of the study.

    RESULTS: International patients always concern about benefits and risks related to travel. These benefits and risks form images of destination in the minds of international patients. Different sources of information make international patients acquaint about the associated benefits and risks, which later leads to development of intention to visit. This conceptual paper helps in establishing model for decision-making process of international patients in developing visit intention.

    CONCLUSION: Ample amount of literature is available detailing different factors involved in travel decision making of international patients; however literature explaining relationship between these factors is scarce.

    In this review, we have investigated the perceptions, barriers, and enabling factors that were responsible for a dietary salt reduction in the out-of-home sectors. For this purpose, we examined different knowledge databases such as Google Scholar, Ebscohost, MEDLINE (PubMed), Ovid, and Cochrane Library for research articles from September to December 2020. The inclusion criteria for the research articles were that they had to be published in English and had to be a qualitative or quantitative study that was conducted after 2010. These studies also had to report the various enablers, barriers, and perceptions regarding salt reduction in the out-of-home sectors. After implementing the inclusion criteria, we successfully screened a total of 440 studies, out of which 65 articles fulfilled all the criteria. The perceived barriers that hindered salt reduction among the out-of-home sectors included lack of menu and food variabilities, loss of sales due to salt reduction, lack of technical skills for implementing the salt reduction processes for cooking or reformulation, and an absence of environmental and systemic support for reducing the salt concentration. Furthermore, the enablers for salt reduction included the intervention programs, easy accessibility to salt substitutes, salt intake measurement, educational availability, and a gradual reduction in the salt levels. With regards to the behavior or perceptions, the effect of organizational and individual characteristics on their salt intake were reported. The majority of the people were not aware of their salt intake or the effect of salt on their health. These people also believed that low salt food was recognized as tasteless. In conclusion, the enablers, barriers, and perceptions regarding salt reduction in the out-of-home sectors were multifaceted. Therefore, for the implementation of the strategies, policies, and initiatives for addressing the barriers, the policymakers need to encourage a multisectoral collaboration for reducing the salt intake in the population.

    BACKGROUND: Nursing colleges have traditionally taught students in hospitals and laboratories. COVID-19 compelled most nursing colleges to embrace e-learning without prior experience or preparation after 2020, which may influence nursing educators' views and attitudes toward its use.

    OBJECTIVE: This scoping review explores the nursing educators' perception of the e-learning approaches used in nursing colleges.

    DESIGN: A comprehensive review of five databases, Cochrane, Ebsco (Medline), PubMed, Science Direct, and Scopus, was conducted, adhering to the Joanna Brings Institute (JBI) standards full theme, utilizing preset eligibility criteria and adhering to the PRISMA Extension for Scoping review (PRISMA-ScR) recommendations.

    METHODS: This scoping review examined studies published in English from January 1st, 2017-2022. Three reviewers evaluated the eligibility of the literature and retrieved data to address the research question from prior literature. A content analysis was done.

    RESULTS: Thirteen articles with various hypotheses and models were reviewed. The review reveals that nursing educators are novices at using e-learning approaches in their classes due to their novelty in most nursing colleges. Nursing educators have a modest positive perception, with an optimistic perspective on e-learning effectiveness in theoretical course teaching, emphasizing that it is inappropriate in teaching clinical courses. The review demonstrates that e-learning faces numerous challenges that negatively impact educators' perceptions.

    CONCLUSION: Institutional preparedness in terms of personnel through educator training, provision of necessary infrastructure, administrative support, and incentives are critical to improving the perception of the e-learning method and increasing its adoption in nursing colleges.

    Pain is modulated by various factors, the most notable of which is emotions. Since love is an emotion, it can also modulate pain. The answer to the question of whether it enhances or reduces pain needs to be determined. A review was conducted of animal and human studies in which this enigmatic emotion and its interaction with pain was explored. Recent advances in neuroimaging have revealed similarities in brain activation relating to love and pain. At the simplest level, this interaction can be explained by the overlapping network structure in brain functional connectivity, although the explanation is considerably more complex. The effect of love can either result in increased or decreased pain perception. An explanation of the interaction between pain and love relates to the functional connectivity of the brain and to the psychological construct of the individual, as well as to his or her ability to engage resources relating to emotion regulation. In turn, this determines how a person relates to love and reacts to pain.

    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.

    Perception is an essential component of children's psychological development, which is foundational to children's ability to understand and adapt to their external environment. Perception is also a crucial tool for understand and navigating one's surroundings, enabling children to identify objects and react appropriately to settings or situations. Substantial evidence indicates that engaging in physical activity is beneficial for the development of children's perceptual abilities, as the two are closely intertwined. Still, more research is necessary to gain a full understanding of the impact of physical activity on children's perception. To further identify and quantify the effects of physical activity on a number of specific perceptions in children. Systematic review and meta-analysis. Searches were performed using five online databases (i.e., PubMed, SPORTDiscus, PsycINFO, Web of Science, and Cochrane Library) for articles published up to and including June 2023 to identify eligible citations. A total of 12 randomized controlled trials, encompassing 1,761 children under the age of 12, were analyzed. Overall, physical activity as an intervention showed a notable effect on the development of children's perceptions. The meta-analysis indicated that participating in physical activity for 30 minutes around, daily, had a greater impact on children's visual perception and executive functioning than on their motor perception, body perception, and global self-worth (SMD = 1.33, 95% CI: 0.75, 1.91, p < 0.001). The effects of physical activity on children's perception performance varied by participant characteristics, with physical activity having better effects on body perception and overall self-worth in children who were obese or overweight. Furthermore, physical activity can also enhance executive function and attention in children with developmental coordination disorders. The effects of physical activity on children's perception performance varied according to the intervention time, with different activity durations resulting in different perception performances. Therefore, parents and educators must prioritize an appropriate length of physical activity time for children to ensure their optimal growth and development. Registration and protocol CRD42023441119.

    BACKGROUND: Occupational exposure to various neurotoxic chemicals has been shown to be associated with colour vision impairment. It seems that this can occur at low exposure levels, sometimes well below the recommended occupational threshold limits. This study was undertaken to determine the effect of exposure to petroleum derivatives (polyethylene, polystyrene) and solvents (perchloroethylene) on colour perception.
    METHODS: Colour vision was assessed using the Ishihara plates, the D-15 test and the Farnsworth Munsell 100 Hue test. Two factories using petroleum derivatives and three dry cleaning premises were chosen at random. A total of 93 apparently healthy employees were recruited from the five workplaces. Two age-matched control groups comprising 56 people, who were support staff of the university with no exposure to petroleum, solvents or their derivatives, were also recruited.
    RESULTS: All subjects passed the Ishihara test, showing that none had a congenital red-green defect. Some of the exposed employees failed the D-15 and had abnormally high FM100 Hue scores. All control subjects passed all the colour vision tests. The D-15 test showed that 28 per cent (26 of 93) of exposed employees had a colour vision defect whereas the FM 100 Hue test found that 63 per cent (59 of 93) had a colour vision defect. Most defects were of the blue-yellow type (22.6 per cent) when using the D-15 test. However, with the FM 100 Hue test, most defects were of the non-polar type with no specific axis (50.5 per cent). Mean total error scores calculated from the FM100 Hue test for exposed employees were statistically significantly higher than those of the control subjects.
    CONCLUSION: Employees directly exposed to petroleum derivatives and solvents have a higher risk of acquiring colour vision defects compared to subjects who are not.
    Study sites: Factories; the control subjects were tested at the Optometry Clinic in Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia.
    Matched MeSH terms: Color Perception/drug effects*; Color Perception Tests
