    Iida F, Nurzaman SG
    Interface Focus, 2016 Aug 06;6(4):20160016.
    PMID: 27499843 DOI: 10.1098/rsfs.2016.0016
    Sensor morphology, the morphology of a sensing mechanism which plays a role of shaping the desired response from physical stimuli from surroundings to generate signals usable as sensory information, is one of the key common aspects of sensing processes. This paper presents a structured review of researches on bioinspired sensor morphology implemented in robotic systems, and discusses the fundamental design principles. Based on literature review, we propose two key arguments: first, owing to its synthetic nature, biologically inspired robotics approach is a unique and powerful methodology to understand the role of sensor morphology and how it can evolve and adapt to its task and environment. Second, a consideration of an integrative view of perception by looking into multidisciplinary and overarching mechanisms of sensor morphology adaptation across biology and engineering enables us to extract relevant design principles that are important to extend our understanding of the unfinished concepts in sensing and perception.

  2. Fulltext Evidence-Based Clinical Practice - A Critical Analysis Of Its Justification And Limitations
    Koh, O.H., Gill, J.S., Pillai, S.K.
    Malaysian Journal of Psychiatry, 2010;19(1):1-6.
    MyJurnal
     Alot has been said and debated about evidence-based clinical practice. What is it really and why so much of significance is attached to it? Is all the evidence from clinical trials relevant and reliable? How about experience-based clinical practice? How much of our practice is influenced by clinical data and how much of it by years of practice and number of patients managed? The clinician will still need to exercise common sense when treating patients and they must always remember that each individual patient is unique and a clinician’s approach will have to be catered to their needs. After all, the caveat is that we are treating individuals with feelings and emotions and not textbooks or journal articles.

    Engkasan JP
    NeuroRehabilitation, 2023;52(1):149-151.
    PMID: 36617764 DOI: 10.3233/NRE-228028
    BACKGROUND: Pressure ulcers may develop in people with impaired mobility, sensation, or cognition. Alternating pressure (active) air beds, overlays and mattresses are commonly used to prevent pressure ulcers.

    OBJECTIVE: This Cochrane Review aimed to determine the effects of alternating pressure (active) air beds, overlays or mattresses compared with any support surface in preventing pressure ulcers.

    METHODS: The population addressed was people at risk of and with existing pressure ulcers. Studies comparing alternating pressure (active) air surfaces with any beds, overlays or mattresses were included. The outcomes studied were pressure ulcer incidence, patient support-surface-associated comfort, adverse events, health-related quality of life and cost-effectiveness.

    RESULTS: There were 32 studies with a total of 9058 participants. There is low certainty evidence that alternating pressure (active) air surfaces compared with foam surfaces may reduce the incidence of pressure ulcers. It is uncertain whether there is a difference in the proportion of people developing new pressure ulcers between alternating pressure (active) air surfaces and reactive water-filled, fibre, air, gel or standard hospital surfaces.

    CONCLUSION: The use of alternating pressure (active) air surfaces may reduce the incidence of pressure ulcers compared to foam surfaces. However, it is uncertain if it is superior to reactive air surfaces, water surfaces and fiber surfaces in preventing pressure ulcers.

    A 25-week feeding trial was conducted to assess the growth performance, organoleptic quality, and to estimate the viability of nourishing hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus) with low-cost fish (LCF) and commercially compound feed (CCF). A group of 3600 juvenile fish (182g) were released in four sea cages and fed with either LCF or CCF in duplicate. At the end of the trial, the hybrid grouper provided LCF attained a significantly higher (P0.05). Although technicalities of fish fed with LCF suggest that LCF is more efficient than CCF, feeding LCF to high-value fish is an unsustainable practice as LCF is usually obtained through trawling – a destructive fishing method for the marine ecosystem. Therefore, feeding with CCF without the use of LCF as the source of protein for its fishmeal will contribute to sustainable aquaculture. In order to convince the local farmers in Sabah to adopt the practice of feeding CCF, future research should focus on completing the species-specific diet formulation to promote optimum growth, and find ways to reduce the CCF local selling price.

  6. Fulltext Influence of hip and knee osteoarthritis on dynamic postural control parameters among older fallers
    Mat S, Ng CT, Tan MP
    J Rehabil Med, 2017 Mar 06;49(3):258-263.
    PMID: 28218341 DOI: 10.2340/16501977-2202
    OBJECTIVE: To compare the relationship between postural control and knee and hip osteoarthritis in older adults with and without a history of falls.
    METHODS: Fallers were those with ≥ 2 falls or 1 injurious fall over 12 months. Non-fallers were volunteers with no falls in the past year. Radiological evidence of osteoarthritis with no reported symptoms was considered "asymptomatic osteoarthritis", while "symptomatic osteoarthritis" was defined as radiographic osteoarthritis with pain or stiffness. Dynamic postural control was quantified with the limits of stability test measured on a balance platform (Neurocom® Balancemaster, California, USA). Parameters assessed were end-point excursion, maximal excursion, and directional control.
    RESULTS: A total of 102 older individuals, mean age 73 years (standard deviation 5.7) years were included. The association between falls and poor performance in maximal excursion and directional control was confounded by age and comorbidities. In the same linear equation model with falls, symptomatic osteoarthritis remained independently associated with poor end-point excursion (β-coefficient (95% confidence interval) -6.80 (-12.14 to -1.42)).
    CONCLUSION: Poor performance in dynamic postural control (maximal excursion and directional control) among fallers was not accounted for by hip/knee osteoarthritis, but was confounded by old age and comorbidities. Loss of postural control due to hip/knee osteoarthritis is not a risk factor for falls among community-dwelling older adults.

  8. Fulltext Impulsivity, online disinhibition, and risk taking among digital millennials: challenges of e-safety in industry 4.0
    Erfianti, Levina Gendis, Nor Diana Mohd Mahudin
    Journal of Occupational Safety and Health, 2019;16(1):45-53.
    MyJurnal
    Digital Millennials (i.e., people born from 1980 to 2004) have often been portrayed as quick to embrace emerging technologies. The envisioned future of Industry 4.0 entails the blending of hardware, software, and people to complete work; and given their affinity for digital resources, technology, and social networking applications, the Millennials could be regarded as a much-needed asset in this future workforce. However, systematic research on how this cohort understands and reacts to safety issues surrounding the use of technologies has been lacking. In particular, behaviours such as impulsivity, online disinhibition, and risk-taking among them remain unclear. The present study investigated this gap with a sample of 203 Millennials of various nationality groups. Using the short version of the Urgency, Premeditation, Perseverance, Sensation Seeking, and Positive Urgency (Short UPPS-P) scale, the Revised Online Disinhibition Scale, and the Online Risky Behaviour scale, the results indicated that the most significant predictors of online risk-taking behaviours are lack of premeditation, positive urgency, and toxic disinhibition. Interestingly, though not hypothesised, was gender as a significant predictor of the outcome. The findings implied that these variables might be the most relevant target areas for interventions that could modify risky behaviours in cyberspace. The study’s findings are discussed in relation to the key challenges associated with e-safety where the future trends would be heading towards the gig economy and crowd-working.

  9. Fulltext Non-Traumatic Snapping Tendon on the Dorsal Aspect of the Thumb: A Diagnostic Challenge
    Kesu Belani L, Abdullah S, Soh EZF, Abd Jabar F, Nasseri Z
    Cureus, 2021 Apr 11;13(4):e14417.
    PMID: 33987066 DOI: 10.7759/cureus.14417
    A snapping tendon on the dorsal aspect of the thumb is a rare condition as opposed to the common triggering on the volar aspect of the thumb. This condition is known as triggering of the extensor pollicis longus (EPL). A 21-year-old female presented with a clicking or snapping sensation that was felt on the dorsum of her thumb when it is extended. There was no history of trauma. She worked in an ice-cream parlor with repetitive scooping ice-cream motions. Her triggering immediately resolved on releasing the EPL fascia ulnar to Lister's tubercle. Upon wake-up surgery, we could immediately confirm this. We recommend dynamic ultrasound as an investigation and do not recommend MRI. The surgical method of choice is either wake-up surgery or wide-awake local anesthesia no tourniquet (WALANT) surgery.

    Nadia Ahmad NF, Nik Ghazali NN, Wong YH
    Biosens Bioelectron, 2021 May 30;189:113384.
    PMID: 34090154 DOI: 10.1016/j.bios.2021.113384
    The advanced stimuli-responsive approaches for on-demand drug delivery systems have received tremendous attention as they have great potential to be integrated with sensing and multi-functional electronics on a flexible and stretchable single platform (all-in-one concept) in order to develop skin-integration with close-loop sensation for personalized diagnostic and therapeutic application. The wearable patch pumps have evolved from reservoir-based to matrix patch and drug-in-adhesive (single-layer or multi-layer) type. In this review, we presented the basic requirements of an artificial pancreas, surveyed the design and technologies used in commercial patch pumps available on the market and provided general information about the latest wearable patch pump. We summarized the various advanced delivery strategies with their mechanisms that have been developed to date and representative examples. Mechanical, electrical, light, thermal, acoustic and glucose-responsive approaches on patch form have been successfully utilized in the controllable transdermal drug delivery manner. We highlighted key challenges associated with wearable transdermal delivery systems, their research direction and future development trends.

    Raw goat milk is recognized as one kind of nutritious food owed to its originality and
    medicinal values. This study aimed to evaluate the physico-chemical and microbiological
    qualities of locally produced raw goat milk prior any processing steps during storage. Milk
    samples passed organoleptic test and C.O.B. test were mostly (88.89 %) failed in alcohol test.
    AOAC Official method of oven drying method, Kjeldahl method and Soxhlet method were
    performed in physico-chemical analysis where results obtained were partially in lined with
    reported literature due to subjective factors of breeds, geographical areas and feeds. The locally
    produced raw goat milk’s compositions are high in water content and low in fat percentage.
    Initial total plate count, coliform count and proteolytic count tested were 3.44 log cfu/ml, 1.87
    log cfu/ml and 1.97 log cfu/ml, respectively. Storage time showed significant effect on the
    bacterial counts (p>0.05) of milk samples. Shelf-life of milk samples were kept up to 12 hours
    under ambient temperature (3.95 log cfu/ml) had not exceeded the standard limit. The shelflife
    of the milk samples were extended up to 16 days storage under refrigerated temperature
    of 4°C. The microbiological quality of the milk samples showed a significant bacteriological
    growth upon prolonged storage and high initial coliform count indicates possible poor hygienic
    practices at farm level.

  13. Fulltext The Development of Expanded Snack Product Made from Pumpkin Flour-Corn Grits: Effect of Extrusion Conditions and Formulations on Physical Characteristics and Microstructure
    Nor NM, Carr A, Hardacre A, Brennan CS
    Foods, 2013 May 14;2(2):160-169.
    PMID: 28239106 DOI: 10.3390/foods2020160
    Pumpkin products confer natural sweetness, desirable flavours and β-carotene, a vitamin A precursor when added as ingredients to extruded snacks. Therefore, a potential use for dried pumpkin flour is as an ingredient in ready-to-eat (RTE) snack foods. Growth in this market has driven food manufacturers to produce a variety of new high value snack foods incorporating diverse ingredients to enhance the appearance and nutritional properties of these foods. Ready-to-eat snacks were made by extruding corn grits with 5%, 10%, 15% and 20% of pumpkin flour. Snacks made from 100% corn grits were used as control products for this work. The effect of formulation and screw speeds of 250 rpm and 350 rpm on torque and specific mechanical energy (SME, kWh/kg), physical characteristics (expansion ratio, bulk density, true density and hardness) and the microstructure of the snacks were studied. Increasing the screw speed resulted in a decrease of torque for all formulations. When pumpkin flour was added the specific mechanical energy (SME) decreased by approximately 45%. Increasing the percentage of pumpkin flour at the higher screw speed resulted in a harder texture for the extruded products. X-ray tomography of pumpkin flour-corn grit snacks showed that increased levels of pumpkin flour decreased both the bubble area and bubble size. However, no significant differences (p > 0.05) in bubble wall thickness were measured. By understanding the conditions during extrusion, desirable nutritional characteristics can be incorporated while maximizing expansion to make a product with low bulk density, a fine bubble structure and acceptable organoleptic properties.

  15. Fulltext Impact of decomposition of autonomic tonic and phasic responses on predictors of reaction performance in elite Malaysian swimmers
    Saha, Srilekha, Saha, Soumendra
    Movement Health & Exercise, 2014;3(1):15-25.
    MyJurnal
    Psychobiological predictors of emotionality were evaluated in relations to complex reaction and movement performances have been considered as the significant aspect of research interest. Considerable research base confirms that the expert players employ more pertinent search strategies, eliminate irrelevant cues which enable them to effectively anticipate action requirements and they have superior ability to use cue-related information to reliably anticipate occurrence of relevant events. Present study was aimed at identification of intricate relationship between the ability of the high performing swimmers (National - level swimmers of Malaysia) in anticipatory cue-utilization and corresponding autonomic phasic skin conductance responses isolated from the tonic measures. Altogether two-hundred and twenty-five individuals having high athletic calibre, and holding top-positions in recently held (within the period March 2011 up to the June 2011) National and International (Mostly ASEAN level) meets volunteered as the participants in this study. Simultaneous evaluation of autonomic arousal modulation (habituation paradigm tonic and phasic measures of skin conductance) was done when the swimmers were engaged in cue-related anticipatory task, associated with complex reaction performance. For this purpose, participants were evaluated intermittently (twice within the calendar year August 2010 - June 2011) with the identical research paradigm. Perceived sense of competence as well as the subjective feelings of apprehension of loosing was explored, and attempts were made to identify the obscure subjective expression of cognitive-emotional make-up, in explaining differential performance outcomes evident in the participants. Findings of multiple linear and polynomial regression analyses however suggested direct, inverse and supportive relationships between decomposition of skin conductance tonic and phasic autonomic components related to cognitive-affective and affective motivational aspects of sports behaviour explaining pathways to both excellent and debilitative performance outcomes during practice sessions as well as in actual competitive situations.

    PMID: 29703880 MyJurnal
    The incidence of intradermal nevus in the external auditory canal is uncommon. We herein are describing a case of 60-year-old lady who presented with foreign body sensation in the right external ear canal (EAC) with mild discomfort and ear bleed during ear picking. Otoscopic examination revealed hyperpigmented mass on the floor of the outer two third of EAC. Complete excisional biopsy of the mass resulted in histopathology findings of intradermal nevus. Despite the fact that the disease is not alarming, the possibilities of benign melanocytic nevi transformation into malignant lesions such as melanoma need to be ruled out.

    International Food Research Journal, 2011;18(1):355-366.
    MyJurnal
    The potential use of medium- and long-chain triacylglycerols (MLCT) oil blends in food applications such as frying oil and salad dressings were investigated. The frying strength of palm-based MLCT oil with different antioxidants under deep frying conditions was assessed. Palm-based MLCT oil showed better thermal-resistant oxidative strength than refined, bleached and deodorized (RBD) palm olein throughout the five consecutive days of frying. Sensory evaluation and rancidity assessment on fried chips showed no significant differences (P > 0.05) between chips fried in RBD palm olein and palm-based MLCT oil. MLCT-based salad dressings treated with different antioxidants showed similar rheological behaviors as compared to soybean based salad dressings. The overall quality of the physical appearance and organoleptic acceptability based on quantitative descriptive analysis showed no significant differences (P > 0.05) in all salad dressings. These findings indicated that MLCT-based oil blends can be used as healthy functional oil for daily consumption.

  18. Fulltext Rambutan seed fat as a potential source of cocoa butter substitute in confectionary product
    Issara, U., Zzaman, W., Yang, T.A.
    International Food Research Journal, 2014;21(1):25-31.
    MyJurnal
    This review of literature provides an overview on the compositional data of Rambutan (Nephelium lappaceum Linn.) and rambutan seed fat for usage in chocolate product. It is a seasonal fruit native of west Malaysia and Sumatra. It is harvested when the fruit have reached optimum visual and organoleptic quality. Rambutans rapidly deteriorate unless proper handling techniques are employed. The rambutan fruits are deseeded during processing and these seeds (~ 4-9 g/100 g) are a waste by-product of the canning industry. And some studies was showed that rambutan seed possesses a relatively high amount of fat and these fats are similar to those of cocoa fat, although have some different physical properties. In the present research about rambutan seed fat continued increasing due to from previous research was found that this fat can use as substitute in cocoa butter for chocolate products. Therefore, the extracted fat from rambutan seed not only could be used for manufacturing candles, soaps, and fuels, but it also has a possible to be a source of natural edible fat with feasible industry use.

    Medically unexplained symptoms (MUS) are increasingly being thought of as resulting from dysfunctional modulation of interoceptive sensory signals by top-down cognitive processes. The current study investigated whether individuals with a tendency toward MUS would be more susceptible to visual illusions that suggest tactile sensation on the skin in the absence of any actual somatosensory input.
