    Objective: : The aim of this study was to evaluate the reliability of the pressure indicating film in measuring pressure exerted on it with and without Polyethylene (PE) sleeve as infection control purposes, and to analyze the pressure produced with its software for occlusal force study. Materials and Methods: The optimization of the pressure indicating film for occlusal force analysis commenced with the design and calibration of this sheet. The film was designed into horseshoe shape to suit the shape of maxillary and mandibular arches. The calibration was initiated with 5 different types of pressure which were 15 MPa, 25 MPa, 30 MPa, 35 MPa and 45 MPa exerted on two groups of the film: (i) with PE sleeve and (ii) without PE sleeve. Three readings were recorded for each group and mean value was documented. Then, the films were calibrated by its software for pressure analysis. Results: There was no significance difference found between the film with and without PE sleeve during the calibration stage (P>0.05). In all groups of pressure, there was no significant difference documented between pressure exerted and read out value. Conclusion: The results suggested that the film can be used for occlusal force analysis and improvement of the film with addition of PE sleeve for hygienic purpose is suitable to form the basis of clinical occlusal forces study.

    BACKGROUND: Medical students' views may provide some direction for future policy considerations.

    AIM: The aim of this study was to assess gender differences in future doctors' receptiveness to currently implemented anti-smoking messages and the effectiveness of those messages.

    MATERIALS AND METHODS: We administered a questionnaire to all students at a medical university in Malaysia, asking how frequently they noted anti- smoking policies, anti-smoking campaigns, and anti-smoking messages in schools. In addition, the questionnaire investigated most effective methods to convey these messages.

    RESULTS: A total of 522 (59.7%) students responded. Students were least likely to approve of total bans on cigarettes and increasing the price of cigarettes, and most likely to approve of bans on use of cigarettes in public places and sales to individuals less than 16 years old. Approval of total bans on cigarettes was more common in female students than in males OR=0.39 (95%CI: 0.18- 0.86). Furthermore, compared to the female students, the male students thought that printed media; OR=2.32 (95%CI: 1.31-4.10), radio; OR=1.93 (95%CI: 1.15-3.22) and the internet; OR=1.96 (95%CI: 1.15-3.33) were very effective at delivering anti-smoking messages.

    CONCLUSIONS: Gender differences existed in the future doctors' perception of the effectiveness of anti-smoking initiatives. Taking this gender difference into account may increase the receipt of anti-smoking messages in adolescents.

    Electrocaloric (EC) materials show promise in eco-friendly solid-state refrigeration and integrable on-chip thermal management. While direct measurement of EC thin-films still remains challenging, a generic theoretical framework for quantifying the cooling properties of rich EC materials including normal-, relaxor-, organic- and anti-ferroelectrics is imperative for exploiting new flexible and room-temperature cooling alternatives. Here, we present a versatile theory that combines Master equation with Maxwell relations and analytically relates the macroscopic cooling responses in EC materials with the intrinsic diffuseness of phase transitions and correlation characteristics. Under increased electric fields, both EC entropy and adiabatic temperature changes increase quadratically initially, followed by further linear growth and eventual gradual saturation. The upper bound of entropy change (∆Smax) is limited by distinct correlation volumes (V cr ) and transition diffuseness. The linearity between V cr and the transition diffuseness is emphasized, while ∆Smax = 300 kJ/(K.m3) is obtained for Pb0.8Ba0.2ZrO3. The ∆Smax in antiferroelectric Pb0.95Zr0.05TiO3, Pb0.8Ba0.2ZrO3 and polymeric ferroelectrics scales proportionally with V cr-2.2, owing to the one-dimensional structural constraint on lattice-scale depolarization dynamics; whereas ∆Smax in relaxor and normal ferroelectrics scales as ∆Smax ~ V cr-0.37, which tallies with a dipolar interaction exponent of 2/3 in EC materials and the well-proven fractional dimensionality of 2.5 for ferroelectric domain walls.

    In this work, the preparation of ZnO, N-doped ZnO (NZO), Al-doped ZnO (AZO) and Al, N-doped ZnO (ANZO) thin films by the sol-gel spin-coating method is reported. The structural properties and surface morphologies of films were characterized by X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM). The optical properties of the films were interpreted from their transmission spectra using UV-VIS spectrophotometer. The XRD and SEM results disclosed that the crystallization quality and grain size of as-prepared films were highly influenced by N and Al doping. UV-VIS spectrophotometer results indicated that Al and N additives could significantly enhance the optical transparency and induce the blue-shift in optical bandgap of ZnO films.

    Previous work has shown that exposure to images of nature results in elevated state body appreciation, but static images may lack ecological validity. Here, we examined the impact of exposure to short films of simulated, first-person walks in natural or built environments. Thirty-six university students completed a measure of state body appreciation before and after watching films of either a walk in a natural or a built environment created specifically for the present study. Two weeks later, they completed the same task but watched the other film type. Results indicated that exposure to the film of a natural environment resulted in significantly elevated state body appreciation (d = 0.66). There was no significant change in state body appreciation following exposure to the film of the built environment (d = 0.14). These findings suggest that exposure to films depicting the natural environment may promote immediate, moderate-sized improvements in state body image.

    This study is premised on the increasing global concerns over the widespread resistance to polio eradication campaign in northern Nigeria. It aims to determine the level of campaign acceptance and compare the influences of mass media and interpersonal communication sources in Zaria local government area, being one of the high-risk (WPV-endemic) areas in northern Nigeria, where campaign resistance is known to be high. By way of quantitative survey, the study utilized 10% sample of the populations of eight out of the thirteen Wards in Zaria local government area, with a response rate of 78.6%. Findings reveal close ranks between campaign acceptance and resistance in the local government area, thus further confirming the difficulties still faced in polio eradication campaign in the region. This study also indicates higher performance of Interpersonal than Mass Media sources in influencing campaign acceptance and resistance in the local communities. Contact with friends and relations was rated the most influential interpersonal sources in the acceptance and resistance decision of individuals, while newspapers and magazines were rated most influential media sources that influenced campaign resistance in the local communities. The study concludes that a polio eradication campaign, backed with competent and sufficient communication expertise that utilizes knowledge-based indigenous interpersonal communication strategies will likely result in greater community acceptance in northern Nigeria.

    This study examined media coverage of COVID-19 in Nigeria with attention to the frequency and depth of coverage, story format, news sources, media tone and themes. Four widely read newspapers were content analysed between February 2020 and April 2020. Focus was on Daily Sun, Vanguard, Daily Trust and Leadership. Results indicated that the Nigerian media performed well in terms of covering the pandemic, which in turn created awareness. However, the coverage was not in-depth as most of the reported stories were short and were predominantly straight news. It was also observed that the media cited more of the Nigeria Centre for Disease Control (NCDC) and government officials. Further findings disclosed that most of the stories were alarming and induced panic. Most common topics were coverage of cases in Nigeria, death rates and concerns about Nigeria's preparedness. Public sensitization and education were sparingly covered. Ethics healthcare workers could adhere to received minimal attention. The media should focus more on sensitizing and educating the public on the necessary steps to take in curbing the virus. They should refrain from over usage of alarming and panic tone in presenting the stories of COVID-19 pandemic in Nigeria.

    OBJECTIVE: The study examines knowledge and perceptions of colorectal cancer vis-à-vis colorectal cancer information in newspapers in Malaysia.

    METHODS: A total of 152 respondents filled in a 76-item questionnaire based on the Health Belief Model. Articles on colorectal cancer in three English newspapers in Malaysia from 1 January to 30 June 2022 were analysed.

    RESULT: A majority of the Malaysian respondents had low experiential knowledge of colorectal cancer, high perceived severity, low perceived susceptibility, and low to moderate susceptibility based on self-reported lifestyle and health conditions. The diet factor puts a majority of respondents at risk but smoking, alcohol drinking, and large intestine problems are risk factors for less than 10% of the group. The respondents believed in the benefits of seeking treatment but they were only marginally positive as to whether quitting smoking and losing weight could reduce colorectal cancer risk. They reported strong response efficacy and self-efficacy but the top barriers were lack of knowledge and cost. The strongest cue to action for their health protective intentions was news about colorectal cancer in newspapers, magazines, television and youtube. There were positive moderate correlations among perceived severity, benefits, response efficacy, self-efficacy, cues to action, and intention. Little salience was given to colorectal cancer in the three English newspapers based on the number of articles (N=10). The high frequency of information on severity, susceptibility, and benefits of lifestyle changes and screening in the newspaper articles are reflected in questionnaire results on better knowledge. Lack of information and cost prevented respondents from seeking screening or treatment, despite attempts by the newspaper articles to address barriers.

    CONCLUSION: The study suggests a need to heighten cues to action in the mass media and social media by providing information on cost and practical details of colorectal cancer screening and benefits of diet-related risk factors.

    This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group.

    Piezoelectric poly(vinyliden fluoride) (PVDF) is attractive because of their low cost, lightweight, biocompatibility and superior mechanical flexibility. Electrophoretic deposition (EPD) technique has the capability of conformally deposit PVDF film on uneven surface target. Nevertheless, knowledge of the role of dispersion formulating process is crucial for achieving an even and uniform PVDF film. Sedimentation test showed PVDF polymer dispersions are more stable and well-dispersed in DMF than in MEK media. For MEK-based dispersion, higher stirring temperature produced less stable and more agglomerated PVDF dispersion, whereas longer stirring time reduced the degree of the PVDF polymer agglomeration. More stable DMF-based dispersions produced lower PVDF depositions than the less stable MEK-based dispersions. PVDF dispersions with higher degree of agglomeration produced films with higher surface roughness and porosity feature.

    The photodegradation rate constant and surface morphology of poly(vinyl chloride), upon irradiation with ultraviolet light was investigated in the presence of polyphosphates as photostabilizers. Poly(vinyl chloride) photodegradation rate constant was lower for the films containing polyphosphates compared to the blank film. In addition, the surface morphology of the irradiated poly(vinyl chloride) containing polyphosphates, examined by scanning electron microscopy, indicates that the surface was much smoother compared to the blank film.

    BACKGROUND: Stigma relating to health can result in a broad range of vulnerabilities and risks for patients and healthcare providers. The media play a role in people's understanding of health, and stigma is socially constructed through many communication channels, including media framing. Recent health issues affected by stigma include monkeypox and COVID-19.

    OBJECTIVES: This research aimed to examine how The Washington Post (WP) framed the stigma around monkeypox and COVID-19. Guided by framing theory and stigma theory, online news coverage of monkeypox and COVID-19 was analyzed to understand the construction of social stigma through media frames.

    METHODS: This research used qualitative content analysis to compare news framings in The Washington Post's online news coverage of monkeypox and COVID-19.

    RESULTS: Using endemic, reassurance, and sexual-transmission frames, The Washington Post predominantly defined Africa as the source of monkeypox outbreaks, indirectly labeled gays as a specific group more likely to be infected with monkeypox, and emphasized that there was no need to worry about the spread of the monkeypox virus. In its COVID-19 coverage, The Washington Post adopted endemic and panic frames to describe China as the source of the coronavirus and to construct an image of panic regarding the spread of the virus.

    CONCLUSIONS: These stigma discourses are essentially manifestations of racism, xenophobia, and sexism in public health issues. This research confirms that the media reinforces the stigma phenomenon in relation to health through framing and provides suggestions for the media to mitigate this issue from a framing perspective.

    The development of news media and social media has radically changed the way the public consumes information. This study explores the structure of online news media networks in three countries, namely Indonesia, Malaysia and Singapore, to investigate the phenomenon of fragmentation in the news consumption pattern on social media. Based on the results of the three network indicators used in this study, it can be concluded that the structure of online news media networks in Indonesia and Malaysia shows a tendency of fragmentation. In contrast, this study did not find sufficient evidence that the phenomenon of fragmentation was occurring in the Singapore media network. In-depth analysis on each formed media cluster shows that online news media in Indonesia and Malaysia tend to group based on similarity in market segments, regions or political alignments.

    The primary health-care approach in Malaysia is an integral part of the government community development movement, or Gerakan Pembaharuan (Operation Renewal), launched in 1972. Nutrition communication activities form a major component of the existing basic health services. The activities are channelled through various health and nutrition services. Group talks, cooking demonstrations with group discussions, individual advice in clinics, and home visits are provided through maternal and child health services. The health education unit is responsible for producing educational materials such as posters and leaflets at both national and state levels. Health education mobile units, fully equipped with audio-visual aids, provide films and slide shows, arrange talks and dialogue sessions, and distribute leaflets. A mass media programme using radio and television was introduced in July 1983 as a joint effort of the ministries of Health and Information. The messages include a wide range of health and nutrition information. Health education materials are used extensively and local radio broadcasts will be utilized to overcome dialect problems. The applied nutrition programme started in 1969 uses an intersectoral approach towards PHC. Four main ministries are involved, namely, Health, Agriculture and Rural Development, Education, and Information. Health and nutrition education is one of the main tasks. Nutrition surveillance is also used as a channel for nutrition communications. In addition, both formal education, such as that provided in nursing schools, and in-service training for health personnel are being conducted by various training schools. The present trend of the health service is shifting from a clinic-based to a community-based approach, in which health staff work closely with community leaders. Attempts to encourage more active community participation in health activities are being made through committee meetings on development at the village and district levels.

    OBJECTIVE: To determine the degree of food environment policies that have been implemented and supported by the Malaysian Government, in comparison to international best practice, and to establish prioritised recommendations for the government based on the identified implementation gaps.

    DESIGN: The Healthy Food-Environment Policy Index (Food-EPI) comprises forty-seven indicators of government policy practice. Local evidence of each indicator was compiled from government institutions and verified by related government stakeholders. The extent of implementation of the policies was rated by experts against international best practices. Rating results were used to identify and propose policy actions which were subsequently prioritised by the experts based on 'importance' and 'achievability' criteria. The policy actions with relatively higher 'achievability' and 'importance' were set as priority recommendations for government action.

    SETTING: Malaysia.

    SUBJECTS: Twenty-six local experts.

    RESULTS: Majority (62 %) of indicators was rated 'low' implementation with no indicator rated as either 'high' or 'very little, if any' in terms of implementation. The top five recommendations were (i) restrict unhealthy food marketing in children's settings and (ii) on broadcast media; (iii) mandatory nutrition labelling for added sugars; (iv) designation of priority research areas related to obesity prevention and diet-related non-communicable diseases; and (v) introduce energy labelling on menu boards for fast-food outlets.

    CONCLUSIONS: This first policy study conducted in Malaysia identified a number of gaps in implementation of key policies to promote healthy food environments, compared with international best practices. Study findings could strengthen civil society advocacies for government accountability to create a healthier food environment.
