    Kaur S, Mursyid A, Ariffin AE
    Journal of Occupational Safety and Health, 2004;1(1):25-30.
    MyJurnal
    A study was undertaken to determine the effect of polyethylene and polystyrene used in the manufacture of plastic items on colour perception. Colour vision was assessed using the Ishihara plates, panel 015 test and the Farnsworth Munsell 100-Hue test. Two factories were chosen at random. One factory (referred here as factory A) used virgin resin in pellet form (polyethylene) in the manufacturing of plastic containers to store consumer edible oil. The other factory (referred as factory B) used polystyrene to make plastic bags. A total of 39 healthy employees from factory A (mean age 26.4 :t 8.2 years) and 40 healthy employees from factory B (mean age 26.8 :t 9.6 years) were recruited in this study. A control group of 27 normal healthy subjects (mean age 27.4 :t 4.3 years) who were employees of UKM with no occupational involvement with petroleum derivatives were also recruited in this study and they performed the same colour vision tests. All subjects passed the Ishihara plates test showing that none of the subjects (employees of factory A and B, and control subjects) had a congenital red-green defect. All control subjects passed all of the colour vision tests whilst some employees of factories A and B failed the 015 and FM100 Hue tests. For employees from factory A results from the 015 test showed that 7 (17.9%) had a tritan (blue-yellow) type of defect and 1 (2.6%) had a complex type of defect. The FM 100 Hue results of factory A employees showed that 51.3% (n=20) had a complex type of defect. Total error scores (TES) calculated from the FM 100 Hue test revealed that employees from factory A had a statistically significant higher mean TES of 65.13:!: 48.31 compared to that of control subjects with a mean TES of 31.26:!: 14.93. For employees in factory B, 10 employees (25.0%) had a tritan (blue-yellow) type of defect and 2 (5.0%) had a complex type of defect. Results of the FM 100 Hue test showed that 4 employees (1.0%) had a tritan type of defect whereas 22 (55.0%) had a complex type of defect. Mean total error scores (TES) calculated from the FM 100 Hue test revealed that employees from factory B had a statistically significant higher mean TES of 71.54 :t 54.63 compared with that of control subjects with a mean TES of 31.26 :t. 14.93

    The above results show that employees of the plastic factories studies are associated with a higher risk of acquiring colour vision defects as compared to normal subjects who are not engaged in the plastic manufacturing industry. This may have an implication towards the future retinal health of employees in petrod1emical-based industries.

  2. Asthma prescribing practices of government and private doctors in Malaysia--a nationwide questionnaire survey
    Loh LC, Wong PS
    Asian Pac J Allergy Immunol, 2005 Mar;23(1):7-17.
    PMID: 15997869
    A self-answered, anonymously completed questionnaire survey was performed between June 2002 and May 2003 where doctors from government and private sectors in Malaysia were invited to participate by post or during medical meetings. One hundred and sixteen government doctors and 110 private doctors provided satisfactorily completed questionnaires (effective respondent rate: 30.1%). The most preferred medications for 'first-line', 'second-line' and 'third-line' treatment were for government doctors: inhaled short-acting beta2-agonist (SABA) (98%), inhaled corticosteroids (CS) (75%), and leukotriene antagonist (52%); and for private doctors: oral SABA (81%), inhaled CS (68%), and oral CS (58%). The first choice inhaler device for most government and private doctors were metered dose inhalers, with cost and personal preferences (for private doctors), and technical ability (for government doctors) as the key considerations when deciding on the choice of device. This benchmark data on the asthma prescribing practices of a healthcare delivery system fully dichotomized into government and private sector, provides evidence for practice differences affected by the nature of the healthcare system, and might have implications on healthcare systems of other countries that share similarities with that of Malaysia.

  3. Fulltext Perceived skill and utilisation of information technology in medical education among final year medical students, Universiti Putra Malaysia
    Lim TA, Wong WH, Lim KY
    Med J Malaysia, 2005 Oct;60(4):432-40.
    PMID: 16570704
    The objective of this survey was to obtain a self-reported assessment of the use of information technology (IT) by final year medical students. Two hundred and sixty five students responded to a questionnaire survey. 81.5% of students considered their computer skills adequate, while 87.9% had access to computers outside the campus. Most students reported adequate skills at word processing, e-mailing and surfing the Internet. Fifty three percent of students spent three hours or more each week on the computer. While students indicated a general willingness to access Internet-based materials, further steps need to be taken to increase the use of this method of instruction.

  4. Fensham's 'Science For All' Vision: A Chemistry Perspective (Visi Fensham 'Sains untuk Semua': Perspektif Kimia)
    Hill JO
    Sains Malaysiana, 2005;34.
    Science has been defined as 'a way of knowing' which is, in certain respects, unlike other ways of knowing. While some forms of knowledge are highly personal and intuitive, the methods of science are designed to be as objective and impersonal as possible. Science has been referred to as 'public knowledge' because of its procedures for verification involve the whole of society. Science is also 'organised knowledge' because it is systematic and because it is supported by a group of social institutions without which it could not exist in its modern form. For many decades, Fensham, an internationally recognised science educator, has been one of the most important and consistent voices for the reform of science education based on his vision of a democratic and socially responsible science education for all, based on the fundamental premise that if society is to understand the world it must be educated in the principles of science upon which a sustainable world is premised. Thus, science has a real place in society and a social responsibility. From a chemistry perspective, this enabling science is perceived by society as irrelevant to the real world and the cause of many of the evils of the world. This paper addresses the pivotal role of chemistry both in science education and in the social responsibility of science campaign and simultaneously shows how chemistry is at the leading edge of sustainable science in both a scientific and social context.
    Sains telah ditakrifkan sebagai 'suatu cara mengetahui'. Dalam ertikata tertentu, takrif ini berlainan dengan cara-cara mengetahui hal-hal lain. Sesetengah bentuk pengetahuan sangatlah tersendiri dan intuitif, namun kaedah sains direkabentuk sedemikian sehingga sejauh mungkin ia berobjektif dan tidak tersendiri. Sains telah dirujukkan sebagai 'pengetahuan awam' kerana prosedur pensahihannya melibatkan seluruh masyarakat. Sains juga merupakan 'pengetahuan yang tersusun' kerana ini bersistem dan kerana ia disokong oleh kumpulan institusi sosial. Tanpa sokongan ini sains tidak boleh wujud dalam bentuk modemnya. Selama beberapa dekad yang lalu, Fensham, seorang ahli pendidikan sains yang diiktiraf antarabangsa, merupakan seorang penggiat yang penting dan konsisten dalam menyuarakan pendapat ke arah perubahan pendidikan sains berdasarkan visinya, iaitu pendidikan sains untuk semua secara demokratik dan bertanggungjawab kepada masyarakat, berlandaskan kepada premis asas bahawa jika masyarakat hendak memahami dunia, maka ia mestilah dididik dalam prinsip-prinsip sains dengan prinsip-prinsip itu sendiri dijadikan premos bagi sebuah dunia mampan. Dengan demikian, sains mempunyai tempatnya yang sebenar dalam masyarakat dan mempunyai tanggungjawab kemasyarakatan. Dari perspektif kimia, masyarakat bertanggapan bahawa sains tersebut tidaklah relevan dalam dunia nyata dan merupakan penyebab kepada banyak keburukan dalam dunia ini. Kertas ini mengupas peranan pengimbangan bidang kimia dalam pendidikan sains dan dalam tanggungjawab sosial kempen sains dan sekali gus menunjukkan bahawa kimia adalah teraju bagi sains mampan dalam kedua-dua konteks sainstifik dan sosial.

  5. Fulltext Problem-based learning as perceived by dental students in universiti sains malaysia
    Barman A, Jaafar R, Ismail NM
    Malays J Med Sci, 2006 Jan;13(1):63-7.
    PMID: 22589593
    The implementation of problem-based learning started in 1969 and has spread since then throughout different parts of the world with variations in its implementation. In spite of its growth and advantages, there is continuing debate about its effectiveness over the conventional teaching learning methods. In the School of Dental Sciences (SDS), Universiti Sains Malaysia (USM), the Doctor of Dental Sciences (DDS) program follows a 5-year integrated curriculum. Basically the curriculum is problem-based and community oriented. This study was to explore the perception of DDS students about PBL sessions. This questionnaires-based cross sectional descriptive study were carried out on all the 110 students of the SDS who completed their second year of the course and participated in PBL sessions. Ninety five (86%) students responded to the questionnaires. Dental students found PBL session interesting and wanted to maintain PBL from the beginning of year 2 up to the end of year 3. Most students reported their participation in discussion during PBL sessions but the level of participation varied. Some of them worked hard to prepare themselves for discussion while others were relatively passive. PBL helped them with in-depth understanding of certain topics and link their basic science knowledge to clinical classes. They felt that guidance from subject specialists and well-prepared facilitators of the sessions were beneficial. The students believed that repetition of triggers from year to year discouraged their active search for learning issues. Majority of the students were undecided or disagreed about the availability of adequate learning resources Most of the students were undecided or disagreed about the availability of adequate learning resources for their self-study. Reviewing and renewing the PBL triggers, providing guidelines for searching for resource materials and briefing the students and facilitators about the philosophy and principles of PBL may make the PBL sessions more beneficial.

  6. A nationwide survey on the knowledge and attitudes of Malaysian optometry students on patients' visual experiences during cataract surgery
    Tan CS, Chen AH, Au Eong KG
    Ann Acad Med Singap, 2006 Feb;35(2):72-6.
    PMID: 16565757
    INTRODUCTION: During cataract surgery under regional (retrobulbar, peribulbar or sub- Tenon's) or topical anaesthesia, many patients experience a variety of visual sensations in their operated eye intraoperatively. Between 3% and 16.2% of patients are frightened by their intraoperative visual experiences, which may increase the risk of intraoperative complications and affect patients' satisfaction with the surgery. This study aims to determine optometry students' beliefs and knowledge of visual sensations experienced by patients during cataract surgery under regional and topical anaesthesia.

    MATERIALS AND METHODS: A nationwide survey of all Malaysian optometry students using a standardised, self-administered questionnaire.

    RESULTS: All 129 optometry students participated in the survey, giving a 100% response rate. Overall, 26.4% and 29.5% of the students believed that patients undergoing cataract surgery under regional and topical anaesthesia, respectively, may experience no light perception, while 78.3% and 72.9%, respectively, thought that patients would experience light perception. Many respondents also believed that patients might experience a variety of other visual sensations. Of all respondents, 70.5% and 74.4% of students believed that patients undergoing cataract surgery under regional and topical anaesthesia, respectively, may be frightened by their visual experience and 93.0% and 85.3%, respectively, felt that preoperative counselling might help to alleviate this fear.

    CONCLUSION: Many optometry students are aware that patients might encounter a variety of visual sensations during cataract surgery under local anaesthesia. A high proportion of students believe that patients may experience fear as a result of the intraoperative visual sensations and felt that preoperative counselling would be helpful.

  7. Effects of a neurotensin analogue (PD149163) and antagonist (SR142948A) on the scopolamine-induced deficits in a novel object discrimination task
    Azmi N, Norman C, Spicer CH, Bennett GW
    Behav Pharmacol, 2006 Jun;17(4):357-62.
    PMID: 16914954
    Various lines of evidence suggest a role in cognition for the endogenous neuropeptide, neurotensin, involving an interaction with the central nervous system cholinergic pathways. A preliminary study has shown that central administration of neurotensin enhances spatial and nonspatial working memory in the presence of scopolamine, a muscarinic receptor antagonist which induces memory deficits. Utilizing similar methods, the present study employed a two-trial novel object discrimination task to determine the acute effect of a neurotensin peptide analogue with improved metabolic stability, PD149163, on recognition memory in Lister hooded rats. Consistent with previous findings with neurotensin, animals receiving an intracerebroventricular injection of PD149163 (3 microg) significantly discriminated the novel from familiar object during the choice trial. In addition, a similar dose of PD149163 restored the scopolamine-induced deficit in novelty recognition. The restoration effect on scopolamine-induced amnesia produced by PD149163 was blocked by SR142948A, a nonselective neurotensin receptor antagonist, at a dose of 1 mg/kg (intraperitonial) but not at 0.1 mg/kg. In conclusion, the present results confirm a role for neurotensin in mediating memory processes, possibly via central cholinergic mechanisms.

  8. Estimating self, parental, and partner multiple intelligences: a replication in Malaysia
    Swami V, Furnham A, Kannan K
    J Soc Psychol, 2006 Dec;146(6):645-55.
    PMID: 17172142
    Participants were 230 adult Malaysians who estimated their own, their parents', and their partners' overall IQs and 10 multiple intelligences. In accordance with both the previous literature and the authors' hypotheses, men rated themselves higher than did women on overall, verbal, logical-mathematical, and spatial intelligences. There were fewer gender differences in ratings of parents and in those of partners. Participants believed that they were more intelligent than both parents (but not their partners) and that their fathers were more intelligent than their mothers. Regressions indicated that participants believed that verbal intelligence and--to a lesser extent--logical-mathematical intelligence were the main predictors of overall intelligence. The authors discussed results in terms of the extant cross-cultural literature in the field.

  9. The effect of intensity on pitch in electric hearing and its relationship to the speech perception performance of cochlear implantees
    Umat C, McDermott HJ, McKay CM
    J Am Acad Audiol, 2006 12 13;17(10):733-46.
    PMID: 17153721
    This study investigated the effect of intensity on pitch in electric hearing and its relationship to the speech perception ability of cochlear implantees. Subjects were 13 adult users of the Nucleus 22 cochlear implant system, using either the Spectra22 or ESPrit22 speech processor and the SPEAK speech processing strategy. A multidimensional scaling technique was employed. Speech perception was measured using sentences and vowels. All measurements were performed in a soundfield condition, and subjects wore their own speech processors with their normally used settings. Results showed a significant correlation between the degree of deviation of the subjects' stimulus spaces from the "ideal" space and subjects' performance with the sentences, but not with the vowels. A significant correlation was found between subjects' response variability in performing the multidimensional scaling task and their speech perception measures, suggesting that spectral smearing or underlying cognitive abilities might affect implantees' speech perception performance.

    PMID: 16984786
    A methodology was developed for diagnosing industrial work, which includes questionnaire, observation, measurements, data collection and statistical analysis. A survey was conducted to investigate the relationship between job satisfaction and factors that affect work design in 2 automotives manufacturing companies in Malaysia. A basic work design model was proposed. The aim of this model was to determine the factors that influence employees' perception towards their work. A set of multiple-choice questionnaires was developed and data was collected by interviewing employees at a production plant. The survey focused on job and environmental factors. The results supported the proposed model and showed that job and environmental factors were significantly related to job satisfaction. They highlighted the significant influence of age, work experience and marital status on job satisfaction. Further, environmental factors, especially the surroundings, context dependence and the building's function, also had a significant impact on job satisfaction.

    Jurnal Sains Kesihatan Malaysia, 2006;4(1):9-20.
    MyJurnal
    The study examined the use of linguistic contextual cues among native, Malay-speaking normal hearing young adults. Ten undergraduate students of Universiti Kebangsaan Malaysia participated in the study. All subjects had normal hearing with the average hearing threshold levels for the overall left and the right ears of 7.8 dB (SD 4.1). The Malay Hearing in Noise Test (MyHINT) materials were employed and presented to the subjects at an approximately 65 dBA presentation level. Testing was conducted in a sound field in three different listening conditions: in quiet, in noise with +5 dB signal-to-noise ratio (SNR) and 0 dB SNR. In every test condition, three lists of MyHINT were administered to each subject. The magnitude of context effects was measured using the j factor, which was derived from measurements of recognition probabilities for whole sentences (13,) and the constituent words in the sentences (PP) in which j = log P./ log P P. Results showed that all subjects scored 100% identification of words in sentences and whole sentences in quiet listening condition, while subjects' performances in 0 dB SNR were significantly poorer than that in quiet and in +5 dB SNR (p < 0.001). The j-values were significantly correlated with the probability of recognizing words in the sentences (r = 0.515, p = 0.029) in which lower j values were associated with lower P ps. Subjects were not significantly different from each other in their use of contextual cues in adverse listening conditions [F(9, 7) = 1.34, p = 0.359]. Using the linear regression function for j on word recognition probabilities, the predicted P. were calculated. It was found that the predicted and measured probabilities of recognizing whole sentences were highly correlated: r = 0.973, p < 0.001. The results suggested that linguistic contextual information become increasingly important for recognition of sentences by normal hearing young adult listeners as SNR deteriorates.

    Quality nursing care has a great impact on patient satisfaction. Quality nursing care is perceived by the post cardiac surgery patient, as the degree of physical, emotional and spiritual needs that have to be fulfilled while hospitalisation. The objective of this study was to identify factors in quality nursing care that determine post cardiac patient satisfaction. This single cross-sectional descriptive study using ‘NURSQUAL’ instrument consisted of four elements; technical competence, information giving, assurance and empathy to measure patient satisfaction with quality nursing care. It consisted of four research questions with 33 items to measure the four elements. Between January to March 2005, 52 post cardiac surgery patients from Institute Jantung Negara (IJN), who fulfilled the inclusion criteria were recruited for this study. There was a significant difference between technical competence, information giving, assurance and empathy with patient satisfaction with p value < 0.05. The element of assurance made the strongest statistically significant unique contribution to the prediction of patient satisfaction with a p value < 0.05.

    Sains Malaysiana, 2006;35:51-55.
    Public perceptions, understanding and acceptance of modern biotechnology can both promote and hamper their commercial introduction and adoption. Various studies have shown that consumer acceptance of modern biotechnology tend to be conditional and dependent on several factors. Public perceptions of biotechnology have received extensive attention in recent years in most Western countries such as Europe, USA and Canada but there have been limited similar surveys in developing countries. Most of the earlier studies used uni-dimensional or bi-dimensional instrument with multi-items or the most is four dimensions with single item. In this study, public attitude towards genetically modified (GM) soybean that is already available in the Malaysian market. A survey was carried out on 577 general public respondents in the Klang Valley region. In order to detect the structure of attitude amongst the expert group in the Klang Valley region, structural equation modeling (SEM) using AMOS version 5.1 was carried out. Result of the survey has confirmed that attitude towards complex issues such as biotechnology should be seen as multi-faceted/ multidimensional process. The most important factors predicting encouragement of GM soybean are the specific application-linked perceptions about the benefits and acceptance of risk while moral concern, risk and familiarity are significant predictors of intermediate factors. Researchers, policy makers and industries interested in developing and marketing GM products in Malaysia should consider the various factors mentioned in this in order to gain public approval.

  15. Fulltext Awareness and perceptions of fibromyalgia syndrome: a survey of Malaysian and Singaporean rheumatologists
    Arshad A, Kong KO
    Singapore Med J, 2007 Jan;48(1):25-30.
    PMID: 17245512
    INTRODUCTION: Fibromyalgia syndrome (FMS) is a common but controversial condition. There appears to be different levels of belief of its existence and awareness. We set out to explore the variations of perceptions and awareness of this condition among rheumatologists from Malaysia and Singapore.
    METHODS: 48 rheumatologists from Malaysia (28) and Singapore (20) were approached to participate in this survey by answering a specific questionnaire regarding their belief in FMS. 23 respondents from Malaysia and 20 from Singapore completed the questionnaire.
    RESULTS: 91 percent of Malaysian rheumatologists and 95 percent of the Singaporean believe that FMS is a distinct clinical entity and that this condition is considered an illness rather than a disease. 87 percent and 90 percent of rheumatologists from Malaysia and Singapore, respectively, believe that FMS is a mixture of medical and psychological illness. However, not many of those in the university setting include FMS in their undergraduate teaching. 87 percent and 80 percent of the respondents from Malaysia and Singapore, respectively, also ordered blood tests to exclude other serious pathologies, and 100 percent of the respondents from both countries also prescribed some form of drugs to their FMS patients.
    CONCLUSION: This study confirmed that there was a variation of perceptions and knowledge of FMS among rheumatologists from Malaysia and Singapore. The majority of rheumatologists recognise that FMS is a distinct clinical entity, and is diagnosed by excluding other well-defined clinical diseases through a combination of clinical evaluation and screening tests.

    Khatijah, L.A.
    JUMMEC, 2007;10(2):37-42.
    MyJurnal
    Leadership style has been shown to be an important determinant of organisational success. The aim of this preliminary study was to develop an understanding of leadership style of three employees with leadership responsibility in a hospital. All the participants were interviewed using a structured questionnaire around a framework on leadership behaviours followed by self administered T-P leadership questionnaire and voluntary completion of a leadership perception survey by each of the participant’s colleagues. The results suggest that whilst individuals are aspiring to be transformational in style, key barriers such as organisational culture, inter-professional dynamics and lack of leadership development meant responses more characteristic of a transactional style were encountered. There is a need to have joint responsibility between developing the individual leadership style and the organisation that facilitates such development for their leaders. The author concludes that a more analytical approach to leadership and mentorship opportunities for developments is required.

    Use of synthetic hydroxyapatite (HA) in biomedical applications is well warranted. It has shown to have an excellent biocompatibility in human tooth and bones. Additionally it has been documented to possess antibacterial potentials. The present study was conducted to assess the presence of any such potential in locally produced (HA) using Streptococcus mutans, a common pathogen in the oral cavity. The study was carried out using 50, 100, 150, 200, 300, 400 and 800 mg/ml concentration of HA. The antibacterial property of HA was assessed using Miles and Misra method. Our studies showed that bacterial growth inhibitions of S. mutans occurred from 50 mg/ml, and complete inhibition was perceived at concentrations at 200mg/ml of HA. The antibacterial property HA should be used to good advantage as a bioactive biomaterial in dental and maxillofacial applications.

    This survey elucidated the perceptions and implementation 0f orthodontic Clinical Practice Guidelines (CPGs) by all ortlmduntistc and dental officers in the Ministry of Health Mahysia (MOH). Two different set: uf xelf-administered questionnaires were targeted at first·year dental officers (FYDO), dental officcrx (DO) and administrative Senior Dental Officers (SDO) in one group and unhocluntists in another group. Only 30% responded from a total of 1,327 MOH dental officers, with no participation from three States. Majority (89%) of officers have heard of CPG: although some were unsure of their purpose and usage. About 69% have read orthodontic CPG; of whom 87% have read other MOH dental CPG:. About 78.6% found CPGs 'gaud to excellenf but 16,0% did not answer this question. Same comments received included: language was confusing, inadequate details and pictures, need improvement, irrelevant, need CPG: for other orthodontic problems, need more knowledge first and requests for mare copies. Only 27.7% used them often, 53% occasionally and 15% hardly follow CPG:. About 82% felt that they were encouraged to use CPGx in their workplace and the majority (86%) knew where they were kept especially SDC: and DO; About 90% in the orthndonzist group have received hard copies of orthodontic CPGs but the majority (76%) has not seen them on the website. Although all felt that CPG; were useful to officers and encouraged their use, only 62.5% have introduced CPGs to their officers. There was generally more awareness and usage of CPGS among SDOs compared with DOs and FY DO; The dissemination and availability of orthodontic CPG: is reasonably good. However, the implementation by mthodontists and administrative officers can be improved for better awareness, understanding and usage by dental officers, especially FYDOs.

    Malaysian Journal of Public Health Medicine, 2007;7(2):15-22.
    MyJurnal
    Cancer screening is an important part of any cancer control program and the success of any screening program is partly dependent on having large numbers of the high risk population availing themselves of the service. The purpose of this study was to assess the cancer screening behavior of fulbtime employed women staff of an institute of higher learning using the Health Belief Model (HBM) construct. The results showed that the rate of reported regular cancer screening behavior (Pap smear screening, breast self examination (BSE), clinical breast examination (CBE) and mammography screening) were low. The rates for regular screening were 42.5% (Pap smear), 20.9% (BSE), 15.5% (CBE) and 9.4% (mammography). There were differences in the dimensions of the HBM between the women who reported regular screening and those that did not. The perceived barriers", "perceived benefits” and “motivation” dimensions were different in Pap smear screening, whereas the "confidence” dimension was different in BSE. Recommendations were made for a health education program targeting both women and men to increase uptake of cancer screening services by women.
