    OBJECTIVES: Preparing future dental school graduates to provide comprehensive patient care with empathy requires the completion of adequate training in such practice. This study was undertaken to investigate the effectiveness of the Photodentistry learning activity, which uses visual arts, in improving dental students' empathy and learning experience in comprehensive patient care.

    METHODS: All fourth-year undergraduate dental students (n = 69, response rate = 100%) participated in the Photodentistry learning activity developed by specialists from the areas of dentistry, arts, education, and psychology. A survey using the Toronto Empathy Questionnaire (TEQ) was conducted both pretest and posttest, followed by an open-ended written survey of their reflection towards the learning activity. Quantitative data were analyzed via paired t-test (P < 0.05), while qualitative data were analyzed using thematic analysis.

    RESULTS: There was a significant increase in both students' total mean empathy score and the individual scores for 8 (out of 16) items of the TEQ after the learning activity. Students stated that they had an improved understanding of managing patients in a comprehensive manner (e.g., managing medically compromised patients, performing treatment planning, communication with patients who have special health care needs). Students also reported the development of skills (e.g., observation, critical thinking) and positive attitudes (e.g., empathy, responsibility) towards patients.

    CONCLUSION: Photodentistry is an effective learning approach for improving dental students' empathy and learning experience in comprehensive patient care.

    This paper presents an ultralow profile, low passive intermodulation (PIM), and super-wideband in-building ceiling mount antenna that covers both the cellular and public safety ultra high frequency (UHF) band for distributed antenna system (DAS) applications. The proposed antenna design utilizes a modified 2-D planar discone design concept that is miniaturized to fit into a small disc-shaped radome. The 2-D planar discone has an elliptical-shaped disc monopole and a bell-shaped ground plane, a stub at the shorting path, with asymmetrical structure and an additional proximity coupling patch to maximize the available electrical path to support the 350 MHz band range. The proposed design maximizes the radome area with a reduction of about 62% compared to similar concept type antennas. Besides, the proposed design exhibits an improved radiation pattern with null reduction compared to a typical dipole/monopole when lies at the horizontal plane. A prototype was manufactured to demonstrate the antenna performance. The VSWR and radiation pattern results agreed with the simulated results. The proposed antenna achieves a band ratio of 28.57:1 while covering a frequency range of 350-10,000 MHz. The measured passive intermodulation levels are better than -150 dBc (2 × 20 Watts) for 350, 700 and 1920 MHz bands.

    Advances in reconfigurable liquid-based reconfigurable antennas are enabling new possibilities to fulfil the requirements of more advanced wireless communication systems. In this review, a comparative analysis of various state-of-the-art concepts and techniques for designing reconfigurable antennas using liquid is presented. First, the electrical properties of different liquids at room temperature commonly used in reconfigurable antennas are identified. This is followed by a discussion of various liquid actuation techniques in enabling high frequency reconfigurability. Next, the liquid-based reconfigurable antennas in literature used to achieve the different types of reconfiguration will be critically reviewed. These include frequency-, polarization-, radiation pattern-, and compound reconfigurability. The current concepts of liquid-based reconfigurable antennas can be classified broadly into three basic approaches: altering the physical (and electrical) dimensions of antennas using liquid; applying liquid-based sections as reactive loads; implementation of liquids as dielectric resonators. Each concept and their design approaches will be examined, outlining their benefits, limitations, and possible future improvements.

    A significant increase has been observed in the use of Underwater Wireless Sensor Networks (UWSNs) over the last few decades. However, there exist several associated challenges with UWSNs, mainly due to the nodes' mobility, increased propagation delay, limited bandwidth, packet duplication, void holes, and Doppler/multi-path effects. To address these challenges, we propose a protocol named "An Efficient Routing Protocol based on Master-Slave Architecture for Underwater Wireless Sensor Network (ERPMSA-UWSN)" that significantly contributes to optimizing energy consumption and data packet's long-term survival. We adopt an innovative approach based on the master-slave architecture, which results in limiting the forwarders of the data packet by restricting the transmission through master nodes only. In this protocol, we suppress nodes from data packet reception except the master nodes. We perform extensive simulation and demonstrate that our proposed protocol is delay-tolerant and energy-efficient. We achieve an improvement of 13% on energy tax and 4.8% on Packet Delivery Ratio (PDR), over the state-of-the-art protocol.

    Currently, smart farming is considered an effective solution to enhance the productivity of farms; thereby, it has recently received broad interest from service providers to offer a wide range of applications, from pest identification to asset monitoring. Although the emergence of digital technologies, such as the Internet of Things (IoT) and low-power wide-area networks (LPWANs), has led to significant advances in the smart farming industry, farming operations still need more efficient solutions. On the other hand, the utilization of unmanned aerial vehicles (UAVs), also known as drones, is growing rapidly across many civil application domains. This paper aims to develop a farm monitoring system that incorporates UAV, LPWAN, and IoT technologies to transform the current farm management approach and aid farmers in obtaining actionable data from their farm operations. In this regard, an IoT-based water quality monitoring system was developed because water is an essential aspect in livestock development. Then, based on the Long-Range Wide-Area Network (LoRaWAN®) technology, a multi-channel LoRaWAN® gateway was developed and integrated into a vertical takeoff and landing drone to convey collected data from the sensors to the cloud for further analysis. In addition, to develop LoRaWAN®-based aerial communication, a series of measurements and simulations were performed under different configurations and scenarios. Finally, to enhance the efficiency of aerial-based data collection, the UAV path planning was optimized. Measurement results showed that the maximum achievable LoRa coverage when operating on-air via the drone is about 10 km, and the Longley-Rice irregular terrain model provides the most suitable path loss model for the scenario of large-scale farms, and a multi-channel gateway with a spreading factor of 12 provides the most reliable communication link at a high drone speed (up to 95 km/h). Simulation results showed that the developed system can overcome the coverage limitation of LoRaWAN® and it can establish a reliable communication link over large-scale wireless sensor networks. In addition, it was shown that by optimizing flight paths, aerial data collection could be performed in a much shorter time than industrial mission planning (up to four times in our case).

    Teachers play an important role in the successful implementation of augmentative and alternative communication (AAC) for students with complex communication needs. The goal of this two-phase, mixed-methods study was to explore Malaysian teachers' use of, experience with, and perceptions about AAC. Phase 1 involved 252 teachers who completed a questionnaire that was aimed at collecting nationwide data about their use and overall perceptions of AAC. Phase 2 involved semi-structured interviews with 13 teachers who had experience supporting students who used AAC. Approximately half of the participants who completed the questionnaire knew about AAC and had used AAC with their students. Almost all of the participants had positive views of AAC though some misconceptions were reported. Most participants had limited knowledge about AAC that led them to experience difficulties supporting their students. Teachers were motivated to receive AAC-related training to enable them to use AAC more successfully with their students given the small number of SLPs in the country.

    BACKGROUND: The COVID-19 health crisis has posed an unprecedented challenge for governments worldwide to manage and communicate about the pandemic effectively, while maintaining public trust. Good leadership image in times of a health emergency is paramount to ensure public confidence in governments' abilities to manage the crisis.

    OBJECTIVE: The aim of this study was to identify types of image repair strategies utilized by the Malaysian government in their communication about COVID-19 in the media and analyze public responses to these messages on social media.

    METHODS: Content analysis was employed to analyze 120 media statements and 382 comments retrieved from Facebook pages of 2 mainstream newspapers-Berita Harian and The Star. These media statements and comments were collected within a span of 6 weeks prior to and during the first implementation of Movement Control Order by the Malaysian Government. The media statements were analyzed according to Image Repair Theory to categorize strategies employed in government communications related to COVID-19 crisis. Public opinion responses were measured using modified lexicon-based sentiment analysis to categorize positive, negative, and neutral statements.

    RESULTS: The Malaysian government employed all 5 Image Repair Theory strategies in their communications in both newspapers. The strategy most utilized was reducing offensiveness (75/120, 62.5%), followed by corrective action (30/120, 25.0%), evading responsibilities (10/120, 8.3%), denial (4/120, 3.3%), and mortification (1/120, 0.8%). This study also found multiple substrategies in government media statements including denial, shifting blame, provocation, defeasibility, accident, good intention, bolstering, minimization, differentiation, transcendence, attacking accuser, resolve problem, prevent recurrence, admit wrongdoing, and apologize. This study also found that 64.7% of public opinion was positive in response to media statements made by the Malaysian government and also revealed a significant positive association (P=.04) between image repair strategies utilized by the Malaysian government and public opinion.

    CONCLUSIONS: Communication in the media may assist the government in fostering positive support from the public. Suitable image repair strategies could garner positive public responses and help build trust in times of crisis.

    The advancement in communication and Internet technology leads to mass of online data available on the Internet. People communicate to each other with application such as Facebook, Twitter, Short Message Service and e-forum. Entries or posts from these applications are known as microtexts. Normally a microtext is very short, very noisy and does not follow the correct structure of a sentence either in the English language or the Malay language. High occurrence of noisy texts decreases the accuracy value when microtexts are processed. This paper proposes a prototype of a system known as Sistem Penterjemahan Mesej Atas Talian (SPMAT). The objective of the system is to 'clean' noisy texts in microtexts that are created online by the Malaysian. 5000 Facebook messages, 5000 Twitter messages and 5000 e-forum messages were collected. From these sources, few lists such as common noisy texts list, common acronyms list artificial abbreviations list and Bi-gram index were created and used in the normalization processed. In addition, the system kept messages that it normalized and updated the corpus when instructed by the user. The methods used in SPMAT had been tested with 100 online messages. The result indicated that 80% of the noisy texts incorporated in these messages had been identified and cleaned correctly.

    Parents play an important role in the successful implementation of AAC. Previous research has indicated that parents in different countries have varying perceptions about the use of AAC and face different challenges in its implementation. To date, there is limited information about the use of AAC by children in Malaysia or parents' views about its use. The aim of this study was to explore Malaysian parents' perception of AAC and their experience when supporting their children who use AAC. For this study, 12 parents of children with autism spectrum disorder and cerebral palsy were involved in semi-structured individual interviews. Qualitative content analysis was used to analyze interview data. Following analysis, three themes were identified: (a) impact of the use of AAC, (b) challenges faced, and (c) hopes and expectations. Participants reported that the use of AAC had a positive impact on their children, but that they faced challenges related to the child, the settings, and the system itself, as well as a lack of time and support. Findings from this study provide an insight for Malaysian speech therapists about the challenges faced by parents when supporting their children who use AAC, and how important it is to overcome these challenges to ensure successful implementation of AAC.

    Collaborative beamforming (CBF) with a finite number of collaborating nodes (CNs) produces sidelobes that are highly dependent on the collaborating nodes' locations. The sidelobes cause interference and affect the communication rate of unintended receivers located within the transmission range. Nulling is not possible in an open-loop CBF since the collaborating nodes are unable to receive feedback from the receivers. Hence, the overall sidelobe reduction is required to avoid interference in the directions of the unintended receivers. However, the impact of sidelobe reduction on the capacity improvement at the unintended receiver has never been reported in previous works. In this paper, the effect of peak sidelobe (PSL) reduction in CBF on the capacity of an unintended receiver is analyzed. Three meta-heuristic optimization methods are applied to perform PSL minimization, namely genetic algorithm (GA), particle swarm algorithm (PSO) and a simplified version of the PSO called the weightless swarm algorithm (WSA). An average reduction of 20 dB in PSL alongside 162% capacity improvement is achieved in the worst case scenario with the WSA optimization. It is discovered that the PSL minimization in the CBF provides capacity improvement at an unintended receiver only if the CBF cluster is small and dense.

    Work-related accidents is a controversial topic in Malaysia as evidenced by the increased number of occupational accidents throughout the years. The purpose of this research is to examine the relationship between management practices and safety performance in an or-ganization. The four management practices investigated are (a) training, (b) management commitment, (c) communication and feedback, and (d) employee involvement. The most effective safety practice is also identified. The data was collected at a manufacturing com-pany located in Shah Alam, Malaysia using closed-ended questionnaire. 95 respondents from the production line were involved in this study. The result found that training had a very weak relationship to the safety performance while the management commitment, as well as the communication and feedback, revealed to have a weak impact on safety perfor-mance. On the other hand, the analysis showed that employee involvement is the most ef-fective safety practice to the safety performance, as it had a moderate impact on safety per-formance.

    The advancement of technology has allowed a variety of tools for employees and
    managers, or knowledge workers, to choose as communication tools, especially for
    managing project teams. Instead of communicating and updating project progress
    through emails and short messaging system, social messaging (SM) applications, such
    as WhatsAppTM, are the current daily choice among them. The over-utilisation of the
    SM applications has given an opportunity for a research on project knowledge
    retention within project team, since it becomes an addiction to create new groups each
    time a new project team is formed. It is believed that project knowledge resides within
    these virtual groups, and this paper looks into how project knowledge is managed by
    analysing the communication patterns against a measurement metrics based on
    personal knowledge management (PKM) theory called GUSC Model. The
    communication patterns found existed in the SM application are qualitatively
    identified and mapped against the PKM processes within, with weighted score
    assigned to each process to quantitatively measure the overall project knowledge
    management participation. The differences among the organisational communication
    levels, namely upper and lower level communication levels, are analysed and the final
    result of participation expectation on member of SM application groups is presented.
    The outcome of this research recommends the future intervention on SM application
    usage and the application of knowledge management concept in current
    communication tool.
