    The current paper is a response to the Wiley, McAllister, Davidson, and Marshall lead article regarding the application of the World Report on Disability (WRD) to people with communication disorders. The current paper directly addresses recommendation 5 (improvement of human resource capacity) and indirectly addresses recommendations 7, 8, and 9 (related to improving local knowledge and data on communicative disabilities) indirectly. The paper describes Malaysia's initiatives in the early 1990s, in developing its local professional capacity to provide services for people with communication disorders (PWCD). It charts the history of development of a local undergraduate entry-level degree program for speech-language pathology (SLP) from the point of conceptualization to full execution. The article provides glimpses to the processes and challenges faced by Universiti Kebangsaan Malaysia as the pioneer university in the South East Asia region to undertake the training and education of the SLP profession and highlights relevant issues faced by newly introduced professions in a country where resources and practice traditions were previously unavailable. It underscores the important role played by government institutions and an international professional network in driving forward-looking policies to implement and sustain the program.

    Wireless Sensor Networks (WSNs) are vulnerable to clone attacks or node replication attacks as they are deployed in hostile and unattended environments where they are deprived of physical protection, lacking physical tamper-resistance of sensor nodes. As a result, an adversary can easily capture and compromise sensor nodes and after replicating them, he inserts arbitrary number of clones/replicas into the network. If these clones are not efficiently detected, an adversary can be further capable to mount a wide variety of internal attacks which can emasculate the various protocols and sensor applications. Several solutions have been proposed in the literature to address the crucial problem of clone detection, which are not satisfactory as they suffer from some serious drawbacks. In this paper we propose a novel distributed solution called Random Walk with Network Division (RWND) for the detection of node replication attack in static WSNs which is based on claimer-reporter-witness framework and combines a simple random walk with network division. RWND detects clone(s) by following a claimer-reporter-witness framework and a random walk is employed within each area for the selection of witness nodes. Splitting the network into levels and areas makes clone detection more efficient and the high security of witness nodes is ensured with moderate communication and memory overheads. Our simulation results show that RWND outperforms the existing witness node based strategies with moderate communication and memory overheads.

    The oral case presentation is an important communicative activity in the teaching and assessment of students. Despite its importance, not much attention has been paid to providing support for teachers to teach this difficult task to medical students who are novices to this form of communication. As a formalized piece of talk that takes a regularized form and used for a specific communicative goal, the case presentation is regarded as a rhetorical activity and awareness of its rhetorical and linguistic characteristics should be given due consideration in teaching. This paper reviews practitioners' and the limited research literature that relates to expectations of medical educators about what makes a good case presentation, and explains the rhetorical aspect of the activity. It is found there is currently a lack of a comprehensive model of the case presentation that projects the rhetorical and linguistic skills needed to produce and deliver a good presentation. Attempts to describe the structure of the case presentation have used predominantly opinion-based methodologies. In this paper, I argue for a performance-based model that would not only allow a description of the rhetorical structure of the oral case presentation, but also enable a systematic examination of the tacit genre knowledge that differentiates the expert from the novice. Such a model will be a useful resource for medical educators to provide more structured feedback and teaching support to medical students in learning this important genre.

    WHAT IS KNOWN AND OBJECTIVE: It has been reported that more than 80% of out-of-hospital medication errors among the young children involve liquid formulations. The usefulness of pictorial aids to improve communication of medication instructions has not been extensively investigated for child health. The objective of this study was to determine the effectiveness of pictorial aids used to assist caregivers in the administration of liquid medications.
    METHODS: MEDLINE, CINAHL, PsycINFO, ScienceDirect, Scopus and the Cochrane Library were searched for articles published up to February 2015. Studies that used pictorial aids with liquid medications and measured at least one of the following outcomes were included: dosing accuracy, comprehension of medication instructions, recall of information and adherence of caregivers. Two authors independently selected studies, extracted data and assessed methodological quality of studies using the Cochrane Collaboration's tool.
    RESULTS AND DISCUSSION: Five experimental studies (four hospital based and one community based) with a total of 962 participants were included. A wide range of liquid formulations were studied, including both prescription and over-the-counter medications. The existing findings suggest that pictographic interventions reduced dosing errors, enhanced comprehension and recall of medication instructions and improved adherence of caregivers. Incorporating pictorial aids into verbal medication counselling or text-based instructions was more beneficial than using the single approach alone. Mixed results were identified for the relationship between health literacy of caregivers and effectiveness of pictorial aids.
    WHAT IS NEW AND CONCLUSION: The evidence remains limited due to the small number of studies found and variations in methodological quality. This review suggests that pictorial aids might be potential interventions, but more high-quality studies are needed to support the routine use of any pictogram-based materials with liquid medications in the clinical settings.

    Multiparty transactional frameworks--i.e. Electronic Data Interchange (EDI) or Health Level (HL) 7--often result in composite documents which can be accurately modelled using hyperlinked document-objects. The structural complexity arising from multiauthor involvement and transaction-specific sequencing would be poorly handled by conventional digital signature schemes based on a single evaluation of a one-way hash function and asymmetric cryptography. In this paper we outline the generation of structure-specific authentication hash-trees for the the authentication of transactional document-objects, followed by asymmetric signature generation on the hash-tree value. Server-side multi-client signature verification would probably constitute the single most compute-intensive task, hence the motivation for our usage of the Rabin signature protocol which results in significantly reduced verification workloads compared to the more commonly applied Rivest-Shamir-Adleman (RSA) protocol. Data privacy is handled via symmetric encryption of message traffic using session-specific keys obtained through key-negotiation mechanisms based on discrete-logarithm cryptography. Individual client-to-server channels can be secured using a double key-pair variation of Diffie-Hellman (DH) key negotiation, usage of which also enables bidirectional node authentication. The reciprocal server-to-client multicast channel is secured through Burmester-Desmedt (BD) key-negotiation which enjoys significant advantages over the usual multiparty extensions to the DH protocol. The implementation of hash-tree signatures and bi/multidirectional key negotiation results in a comprehensive cryptographic framework for multiparty document-objects satisfying both authentication and data privacy requirements.

    In this paper, we present a Java-based framework for the processing, storage and delivery of Electronic Medical Records (EMR). The choice of Java as a developmental and operational environment ensures operability over a wide-range of client-side platforms, with our on-going work emphasising migration towards Extensible Markup Language (XML) capable Web browser clients. Telemedicine in support of womb-to-tomb healthcare as articulated by the Multimedia Supercorridor (MSC) Telemedicine initiative--which motivated this project--will require high-volume data exchange over an insecure public-access Wide Area Network (WAN), thereby requiring a hybrid cryptosystem with both symmetric and asymmetric components. Our prototype framework features a pre-transaction authentication and key negotiation sequence which can be readily modified for client-side environments ranging from Web browsers without local storage capability to workstations with serial connectivity to a tamper-proof device, and also for point-to-multipoint transaction processes.

    The teaching of clinical communication skills to undergraduate medical students in the Faculty of Medicine, University of Malaya is described. It is a continuous process throughout the five-year medical curriculum which is divided into Phases I, II and III. Students are introduced to communication skills early in Phase I through an interactive session as well as a workshop on general communication skills. In Phase II, small-group two-day workshops cover the basic principles of clinical communication skills using videotapes, group discussion and role-plays. Direct contact between students and patients in actual clinical setting begin in Phase IIIA. Communication skills teaching with feedback training is carried out by videotaping the consultations. In Phase IIIB the two-way mirror is utilized as well as having workshops on certain difficult areas such as 'breaking bad news' and 'taking a sexual history'. Formal assessment is done by evaluating the behavior, language and actual interview content.

    A system for computerising full blood picture reporting developed in-house using dBASE IV on IBM-compatible microcomputers in a local area network environment is described. The software package has a user-friendly interface which consists of a horizontal main menu bar with associated pull-down submenus. The package captures data directly from an automatic blood cell counter and provides options to modify or delete records, search for records, print interim, final or cumulative reports, record differential counts with an emulator, facilitate house-keeping activities which include backing-up databases and repairing corrupted indices. The implementation of this system has helped to improve the efficiency of reporting full blood picture in the haematology laboratory.

    A number of health databases is now available in Malaysia, but few are accessible to the general public. However, recently a service was launched nationwide via a videotex system to also target the Malaysia public. This service is provided by the School of Pharmaceutical Sciences, Universiti Sains Malaysia (USM) in collaboration with several Malaysian Government ministries and agencies. Access to health information via videotex, be it medical, pharmaceutical or environmental is viewed as an effective means of on-line information dissemination. It provides not only rapid retrieval but is also economical and interactive, particularly suitable for a developing country.

    OBJECTIVE: The study was to examine the role of children in communication and decisions regarding their nursing care in a paediatric oncology ward in Malaysia.

    METHODS: The principles of focused ethnography underpinned the study design. Fieldwork took place over six months in one 32-bedded paediatric oncology ward. Twenty-one children, ranging in ages from 7 to 12 years diagnosed with leukaemia, their parents and 19 nurses participated. Data collection consisted of participant observation and semi-structured interview.

    RESULTS: Hospitalized children employed different roles of passive or active participants during the communication and decisions about their nursing care. Importantly, children are more likely to become active participants in the communication process when nurses interact directly with them, listening to them and giving them opportunities to ask questions in either the presence or absence of their parents. Equally, children are likely to be more passive participants when nurses do not communicate directly with them, choosing instead to directly interact with the child's parents. This study highlighted that the role of children as active and passive participants is not permanently engaged by individual children, rather their role fluctuates throughout the hospitalization journey. The fluctuations of a child's role are highly dependent on their preferences: how and when they want to be included in the communication and decisions process. Children's roles in communication and decisions are also varied and dependent on their particular contexts. A child's participation in one situation does not consistently reflect their participation with their role in other situations. The ways in which the children participate were oscillated throughout their hospitalization.

    CONCLUSIONS: This study provides empirical insight into children's experiences of triadic (child-nurse-parent) interaction during the decisions about their nursing care in paediatric oncological setting. A key recommendation calls for the development of assessment strategies to determine the 'ideal' position children would like to occupy, at any given point in time, throughout their hospitalization.

    Localization of the wireless sensor network is a vital area acquiring an impressive research concern and called upon to expand more with the rising of its applications. As localization is gaining prominence in wireless sensor network, it is vulnerable to jamming attacks. Jamming attacks disrupt communication opportunity among the sender and receiver and deeply impact the localization process, leading to a huge error of the estimated sensor node position. Therefore, detection and elimination of jamming influence are absolutely indispensable. Range-based techniques especially Received Signal Strength (RSS) is facing severe impact of these attacks. This paper proposes algorithms based on Combination Multiple Frequency Multiple Power Localization (C-MFMPL) and Step Function Multiple Frequency Multiple Power Localization (SF-MFMPL). The algorithms have been tested in the presence of multiple types of jamming attacks including capture and replay, random and constant jammers over a log normal shadow fading propagation model. In order to overcome the impact of random and constant jammers, the proposed method uses two sets of frequencies shared by the implemented anchor nodes to obtain the averaged RSS readings all over the transmitted frequencies successfully. In addition, three stages of filters have been used to cope with the replayed beacons caused by the capture and replay jammers. In this paper the localization performance of the proposed algorithms for the ideal case which is defined by without the existence of the jamming attack are compared with the case of jamming attacks. The main contribution of this paper is to achieve robust localization performance in the presence of multiple jamming attacks under log normal shadow fading environment with a different simulation conditions and scenarios.

    In heterogeneous wireless networks, wireless local area network (WLAN) is highly preferred by mobile terminals (MTs) owing to its high transmission bandwidth and low access cost. However, in high-speed environment, handover from a cellular network to a WLAN cell will lead to a high number of handover failures and unnecessary handovers due to the WLAN coverage limitation and will become worse at high speed. A new vertical handover method is proposed to minimize the probability of handover failure and unnecessary handover while maximizing the usage of WLAN in high-speed environment. The simulation results show that the proposed method kept the probability of handover failure and unnecessary handover below 0.5% and 1%, respectively. Compared with previous studies, the proposed method reduced the number of handover failures and unnecessary handovers up to 80.0% and 97.7%, respectively, while the MT is highly mobile. Using the proposed prediction method, the MT can benefit high bandwidth and low network access cost from the WLAN with minimum interruption regardless of speed.

    BACKGROUND: Unhealthy food marketing to children is a key risk factor for childhood obesity. Online video platforms have surpassed television as the primary choice for screen viewing among children but the extent of food marketing through such media is relatively unknown. We aimed to examine food and beverage advertisements (ads) encountered in YouTube videos targeting children in Malaysia.

    METHODS: The social media analytics site SocialBlade.com was used to identify the most popular YouTube videos (n = 250) targeting children. Ads encountered while viewing these videos were recorded and analyzed for type of product promoted and ad format (video vs. overlay). Food and beverage ads were further coded based on food category and persuasive marketing techniques used.

    RESULTS: In total 187 ads were encountered in sampled videos. Food and beverage ads were the most common at 38% (n=71), among which 56.3% (n = 40) promoted noncore foods. Ads for noncore foods were more commonly delivered as video rather than overlay ads. Among ads promoting noncore foods, the most commonly employed persuasive marketing techniques found were taste appeal (42.3%), uniqueness/novelty (32.4%), the use of animation (22.5%), fun appeal (22.5%), use of promotional characters (15.5%), price (12.7%), and health and nutrition benefits (8.5%).

    CONCLUSIONS: Similar to television, unhealthy food ads predominate in content aimed toward children on YouTube. Policies regulating food marketing to children need to be extended to cover online content in line with a rapidly-evolving digital media environment. Service providers of social media can play a part in limiting unhealthy food advertising to children.

    The VoIP services provide fertile ground for criminal activity, thus identifying the transmitting computer devices from recorded VoIP call may help the forensic investigator to reveal useful information. It also proves the authenticity of the call recording submitted to the court as evidence. This paper extended the previous study on the use of recorded VoIP call for blind source computer device identification. Although initial results were promising but theoretical reasoning for this is yet to be found. The study suggested computing entropy of mel-frequency cepstrum coefficients (entropy-MFCC) from near-silent segments as an intrinsic feature set that captures the device response function due to the tolerances in the electronic components of individual computer devices. By applying the supervised learning techniques of naïve Bayesian, linear logistic regression, neural networks and support vector machines to the entropy-MFCC features, state-of-the-art identification accuracy of near 99.9% has been achieved on different sets of computer devices for both call recording and microphone recording scenarios. Furthermore, unsupervised learning techniques, including simple k-means, expectation-maximization and density-based spatial clustering of applications with noise (DBSCAN) provided promising results for call recording dataset by assigning the majority of instances to their correct clusters.

    One of the major problems causing medication errors is ineffective
    communication between patients and health personnel. This paper discusses
    the communication issues in the healthcare environment and how
    medication errors can be avoided through effective communication. An
    internet-based search was conducted to locate relevant articles published
    between 2004 and 2017. Only articles that touch upon communication and
    health-related issues were selected. Online sources such as PubMed,
    ScienceDirect, and Google Scholar were utilized. The importance of good
    communication practices for effective health and improved patient safety in
    hospital settings has been highlighted. It is evident from this review that
    poor communication most frequent causes adverse effects, delay in
    treatment, medication errors, and wrong-site surgery. The major
    communication issues in healthcare environment include language barriers,
    the medium of communication, physical setting, and social setting.
    Healthcare workers tend to use technical language in the workplace because
    they consider the tone of communication to be always professional. It has
    been established that knowledge on professional-patient communication is
    essential and valuable in improving therapeutic outcomes. Patients need
    knowledge and support in order to be able and motivated to undergo
    medicine therapy. Health practitioners need to take responsibility for
    demanding and creating an environment where high-quality healthcare
    counselling is routinely practiced. To promote safe and effective practice in hospitals and avoid medication errors, clinicians should adhere to teamwork
    and effective communication with the patients. There is a need for designing
    strategies such as effective communication and teamwork amongst
    healthcare professionals, which can consequently influence the quality of
    healthcare services and patient outcomes.

    OBJECTIVE: Language and symbolic play require the same underlying symbolic ability and develop parallel to one another. The aim of this study was to determine the association between symbolic play and vocabulary in typically developing children and children with Down syndrome in Malaysia.

    METHODS: Twenty-five typically developing children and 25 children with Down syndrome aged between 12 and 36 months were involved in this study. They were recruited from an early intervention center and various kindergartens from the West Coast of Peninsular Malaysia. Their play skills were assessed using the Symbolic Play Test Second Edition, and information about their vocabulary was obtained through the MacArthur Bates Communicative Development Inventories that was filled out by their parents.

    RESULTS: There was a significant difference in the vocabulary and symbolic play scores of children with Down syndrome compared with typically developing children. There was also a positive correlation between symbolic play scores and receptive and expressive vocabulary scores for both groups of children.

    CONCLUSION: When providing intervention, speech-language pathologists need to promote the development of symbolic play in addition to language, given the association between the two. They should also look into introducing an augmentative and alternative communication system to the children who demonstrate age-appropriate symbolic play skills but have trouble with symbolic language production.

    Ageing and age-related diseases share some basic origin that largely converges on inflammation. Precisely, it boils down to a common pathway characterised by the appearance of a fair amount of proinflammatory cytokines known as inflammageing. Among the proposed treatment for antiageing, MSCs gained attention in recent years. Since mesenchymal stem cells (MSCs) can differentiate itself into a myriad of terminal cells, previously it was believed that these cells migrate to the site of injury and perform their therapeutic effect. However, with the more recent discovery of huge amounts of paracrine factors secreted by MSCs, it is now widely accepted that these cells do not engraft upon transplantation but rather unveil their benefits through excretion of bioactive molecules namely those involved in inflammatory and immunomodulatory activities. Conversely, the true function of these paracrine changes has not been thoroughly investigated all these years. Hence, this review will describe in detail on ways MSCs may capitalize its paracrine properties in modulating antiageing process. Through a comprehensive literature search various elements in the antiageing process, we aim to provide a novel treatment perspective of MSCs in antiageing related clinical conditions.
