    Evaluation of the mechanical behaviour of restoration dental materials is essential to understand their performance under different load conditions and to estimate their durability under clinical oral function. Restorative materials and dental tissues like other materials by having specific mechanical properties, such as static strength (i.e. compressive strength, tensile strength, flexural strength) and dynamic strength (i.e. fatigue strength). The selection of proper mechanical test type depends on the goals that the study claims to define. On such basis, the mechanical test can be chosen correctly. Laboratory studies should be designed as replications of the clinical oral circumstances to measure the mechanical and physical properties of a material and any arbitrary choices in the design of the study may result in large variations of data.

    Unsafe behaviour is the key factor which contributes to the high number of incidents. Applying Behavior-Based
    Safety (BBS) into safety risk controls has been adopted in major industry toward improving safety performance.
    This approach to prevent incident has a number of advantages. The objective of this study is to identify the BBS
    factors which can contribute to reduce incidents at the workplace. Human factors, behaviour and environment have
    been identified as BBS factors. Human factors are influenced by knowledge and understanding of the workers while
    behaviour factors are influenced by culture and practices in a daily life. In addition, environmental factor involves
    equipment and work area. For an effective BBS approach, level of knowledge, understanding and practices by the
    workers become the main concerns in the implementation of BBS. The findings can become the reference model for
    future implementation in other organizations and as a guidance for better safety management.

    PMID: 16854709
    In developing countries, motorcycle use has grown in popularity in the past decades. Commensurate with this growth is the increase in death and casualties among motorcyclists in these countries. One of the strategic programs to minimize this problem is to reduce motorcyclists exposure by shifting them into safer modes of transport. This study aims to explore the differences in the characteristics of bus and motorcycle users. It identifies the factors contributing to their choice of transport mode and estimates the probability that motorcyclists might change their travel mode to a safer alternative; namely, bus travel.

    Sains Malaysiana, 2011;40:1097-1103.
    The aqueous extract of Prismatomeris glabra root has been used traditionally in Malaysia by the aborigines and certain rural Malays for its ergogenic effects, to maintain wellness and to enhance physical stamina. It has also been used as an aphrodisiac for generations in the east coast of Peninsular Malaysia. Previous studies have shown that plants with ergogenic effects may also act as a stimulant and impair cognitive function. Therefore, we seek to investigate the effects of P. glabra on non-spatial memory in male Sprague Dawley rats using object recognition test. Trial rats were injected intraperitoneally with an aqueous extract of P. glabra roots at doses of 50 and 100 mg/kg for the acute (30 min) and subacute (7 days) studies. Scopolamine (0.3 mg/kg) was used as a positive control only in the acute study meanwhile control rats were injected with saline. The locomotor activity of rats was also determined in the same test. We demonstrated that groups treated with 50 and 100 mg/kg of the extract lost their ability to discriminate the novel from familiar object in choice phase and did not alter the locomotor activity in both studies. Our results also indicated that the deficits in non-spatial working memory occured at these doses were not due to impaired locomotor activity.

  5. Religious scholars' attitudes and views on ethical issues pertaining to pre-implantation genetic diagnosis (PGD) in Malaysia
    Olesen A, Nor SN, Amin L
    J Bioeth Inq, 2016 Sep;13(3):419-29.
    PMID: 27365102 DOI: 10.1007/s11673-016-9724-2
    Pre-Implantation Genetic Diagnosis (PGD) represents the first fusion of genomics and assisted reproduction and the first reproductive technology that allows prospective parents to screen and select the genetic characteristics of their potential offspring. However, for some, the idea that we can intervene in the mechanisms of human existence at such a fundamental level can be, at a minimum, worrying and, at most, repugnant. Religious doctrines particularly are likely to collide with the rapidly advancing capability for science to make such interventions. This paper focuses on opinions and arguments of selected religious scholars regarding ethical issues pertaining to PGD. In-depth interviews were conducted with religious scholars from three different religious organizations in the Klang Valley, Malaysia. Findings showed that Christian scholars are very sceptical of the long-term use of PGD because of its possible effect on the value of humanity and the parent-children relationship. This differs from Islamic scholars, who view PGD as God-given knowledge in medical science to further help humans understand medical genetics. For Buddhist scholars, PGD is considered to be new medical technology that can be used to save lives, avoid suffering, and bring happiness to those who need it. Our results suggest that it is important to include the opinions and views of religious scholars when it comes to new medical technologies such as PGD, as their opinions will have a significant impact on people from various faiths, particularly in a multi-religious country like Malaysia where society places high value on marital relationships and on the traditional concepts of family.

    Pondor I, Gan WY, Appannah G
    Nutrients, 2017 Sep 16;9(9).
    PMID: 28926947 DOI: 10.3390/nu9091028
    Food price is a determining factor of food choices; however its relationship with diet quality is unclear in Malaysia. This study aimed to examine socio-economic characteristics and daily dietary cost (DDC) in relation to diet quality in the state of Selangor, Malaysia. Dietary intake was assessed using a Food Frequency Questionnaire (FFQ) and diet quality was estimated using a Malaysian Healthy Eating Index (M-HEI). DDC in Malaysian Ringgit (RM) was calculated from dietary intake and national food prices. Linear regression models were fitted to determine associations between DDC and M-HEI scores and predictors of diet quality. The mean M-HEI score of respondents was 61.31 ± 10.88 and energy adjusted DDC was RM10.71/2000 kcal (USD 2.49). The highest quintile of adjusted DDC had higher M-HEI scores for all respondents (Q1: 57.14 ± 10.07 versus Q5: 63.26 ± 11.54, p = 0.001). There were also positive associations between DDC and M-HEI scores for fruits (p < 0.001) and vegetables (p = 0.017) for all respondents. Predictors of diet quality included carbohydrate (β = 0290; p < 0.001) and fat intakes (β = -0.242; p < 0.001) and energy adjusted DDC (β = 0.196; p < 0.001). Higher dietary cost is associated with healthy eating among Malaysian adults.

  7. Fulltext Knowledge, Attitude, Exposure, and Future Intentions toward Exclusive Breastfeeding among Universiti Sains Malaysia Final Year Medical and Dental Students
    Mohamad N, Saddki N, Azman KNK, Aziz IDA
    Korean J Fam Med, 2019 Jul;40(4):261-268.
    PMID: 30625269 DOI: 10.4082/kjfm.18.0021
    BACKGROUND: Breastmilk is the best nourishment for an infant for the first 6 months of life. Health professionals like medical doctors and dentists can help promote and support exclusive breastfeeding. We aimed to assess knowledge, attitudes, exposure, and future intentions toward exclusive breastfeeding among final year medical and dental students at Universiti Sains Malaysia, Kelantan, Malaysia.

    METHODS: A total of 162 students participated in this cross-sectional study that was conducted between May and September of 2015. Self-administered questionnaires were used to collect the variables of interest.

    RESULTS: Most students knew exclusive breastfeeding is recommended for the first 6 months of life (98.1%). However, some students incorrectly thought formula milk can be given if the infant appears hungry after having been breastfed (61.7%). Additionally, some incorrectly thought expressed breastmilk can be warmed on direct heat (47.5%) and left-over expressed milk can be re-stored (60.5%). Most students agreed that exclusive breastfeeding is easier to practice than formula feeding and that it is the best choice for working mothers. Most students (93.2%) intend to breastfeed their children, and this intention was significantly associated with their experience being breastfed as infants and attitudes toward exclusive breastfeeding.

    CONCLUSION: Generally, final year medical and dental students have favorable attitudes and future intentions toward exclusive breastfeeding, although some of them lacked knowledge about certain important aspects of the practice. Past experience of being exclusively breastfed and a more positive attitude toward the practice were associated with their future intentions to practice exclusive breastfeeding.

  9. Life events and stress: do older men and women in Malaysia cope differently as consumers?
    Ong FS, Phillips DR, Chai ST
    J Cross Cult Gerontol, 2013 Jun;28(2):195-210.
    PMID: 23652824 DOI: 10.1007/s10823-013-9190-9
    The study of major life events and their effects on well-being has considerable relevance for scientific disciplines and policy making in understanding the consumer behaviour of older people. There is evidence of differences in reactions to and coping with stress between males and females but relatively little knowledge about such gender differences amongst older people, especially in middle-income countries. This study of older Malaysians looked at both coping strategies and gender differences in reactions to stress when people are confronted with certain life events. Seventeen major life events were used in interviews with 645 respondents aged 50 years or older in five major urban areas in Peninsular Malaysia. The analysis showed older women tended to experience higher levels of chronic stress than older men. They also had more health problems, had lower levels of self-esteem and were less satisfied with life. Whilst the results showed little support for gender differences in coping behaviours, stress had a significant influence on the way older men and women change store preferences. A hypothesis that older women would use more emotion-focused coping strategies was not supported. Knowledge of how older Malaysians cope with life events and stress and especially in this instance with regard to consumption behaviour, is likely to be of considerable academic and policy related interest.

  10. Choice and constraints in floodplain occupation: the influence of structural factors on residential location in peninsular Malaysia
    Chan NW
    Disasters, 1995 Dec;19(4):287-307.
    PMID: 8564454
    In Peninsular Malaysia 'structural' factors are found to influence strongly people's persistent occupation of floodplains. Thus, despite a high level of flood hazard awareness, a high level of pessimism and a high level of expectation of future floods, poorer individuals seldom attempt to leave for more advantageous locations but are instead trapped in their present locations by structural factors such as poverty, low residential and occupational mobility, low educational attainment, traditional land inheritance, government aid, and government disaster preparedness, relief and rehabilitation programmes. These forces exert a strong influence upon individuals and largely control their choice of residential location in response to flood hazards, thereby reinforcing the persistent occupation of floodplains. Structural factors such as landlessness, rural-urban migration, floodplain encroachment and squatting are also highly influential in leading people to move. Even for those who move, structural factors have largely confined their choice of residential location to urban floodplains.

  11. Choosing health, constrained choices
    Chee Khoon Chan
    Glob Health Promot, 2009 Dec;16(4):54-7.
    PMID: 20028669 DOI: 10.1177/1757975909348131
    In parallel with the neo-liberal retrenchment of the welfarist state, an increasing emphasis on the responsibility of individuals in managing their own affairs and their well-being has been evident. In the health arena for instance, this was a major theme permeating the UK government's White Paper Choosing Health: Making Healthy Choices Easier (2004), which appealed to an ethos of autonomy and self-actualization through activity and consumption which merited esteem. As a counterpoint to this growing trend of informed responsibilization, constrained choices (constrained agency) provides a useful framework for a judicious balance and sense of proportion between an individual behavioural focus and a focus on societal, systemic, and structural determinants of health and well-being. Constrained choices is also a conceptual bridge between responsibilization and population health which could be further developed within an integrative biosocial perspective one might refer to as the social ecology of health and disease.

  12. Relationship between work-family conflict and unhealthy eating: Does eating style matter?
    Shukri M, Jones F, Conner M
    Appetite, 2018 04 01;123:225-232.
    PMID: 29294321 DOI: 10.1016/j.appet.2017.12.027
    There is increasing evidence to suggest that work-family conflict is implicated in poor eating patterns. Yet, the underlying mechanism remains unexplored. The objectives of the present study were to demonstrate the interplay between work-family conflict, eating style, and unhealthy eating, and to test whether body mass index (BMI) and its interactions further explicate the relationships. In this study, 586 Malaysian adults (normal weight n = 437, overweight n = 149) completed a questionnaire, which included demographic variables, work-family scales, eating style measures, namely, restrained, emotional or external eating and reported food intake. As hypothesized, results showed that family-to-work conflict (FWC), emotional eating and external eating were positively related to unhealthy food consumption. In addition, emotional eating was found to moderate the impact of FCW on eating. These findings are consistent with research that has revealed emotional eating can indeed increase the positive association between stress such as conflict and unhealthy food choices. However, we found no clear support for the interactive effects of BMI. Our research builds on the findings of existing research as it demonstrates the role of eating style in explaining the association between work-family conflict and unhealthy eating. This conclusion has potential implications for appropriate interventions and calls for the enhancement of various policies to tackle obesity and other health problems.

    Subdermal etonogestrel implant (Implanon®) is the newest, long term contraceptive implant which has recently been made available to Malaysian women. This prospective study was conducted to determine the effects on selected health indices among 42 women who had consented to Implanon® as their choice of contraception. Health indices were checked prior to Implanon® insertion and six months post insertion. Findings indicate a significant reduction in total cholesterol with a significant increase in total haemoglobin and BMI. However there was no significant change noted in the fasting blood sugar, glycosylated haemoglobin, systolic blood pressure and diastolic blood pressure.

  15. Contraceptive method switching over women's reproductive careers: evidence from Malaysian life history data, 1940s-70s
    DaVanzo J, Reboussin D, Starbird E, Tan BA, Hadi SA
    J Biosoc Sci Suppl, 1989;11:95-116.
    PMID: 2489987
    Several new concepts are used to describe contraceptive use histories for nearly 1200 women in Peninsular Malaysia. These histories are summarized by 81 episode histories. Transition matrices provide useful summaries of the changes women make in their contraceptive practice from one pregnancy interval to the next. Data from the mid-1940s to mid-1970s, during which period there was a dramatic increase in contraceptive use, reveal considerable inertia in individual couples' contraceptive practice. Persistence with a method was greater the less effective the method: while 86% of couples using no method in one interval used no method in the next, only 56% of couples using the pill in one interval also used it in the next. Virtually all transitions are of three types: continuation with the same method, a change from no method to some method, or a change from some method to no method. For only 1% of all pregnancies did couples use one contraceptive method before a pregnancy and a different method after the pregnancy. Differences are examined by calendar year and education.

    PMID: 33597488
    The extent of the economic burden of malaria and its imposed mechanisms are both relevant to public policy. This paper investigates the economic burden of malaria and household behaviour in relation to the treatment and prevention of the illness in Pakistan. In this regard, data were collected from a randomly selected sample of 360 households using structured questionnaires. The survey results indicate that 23.4% of household members contracted malaria during the three-month reference period. The average per person cost of malaria is estimated at 3116 Pakistani rupees (PKR) (USD 32). The estimated cost of the illness was found to be equivalent to, on average, 6.7% of monthly household income. Although high-income households face a higher financial burden due to better preventive and mitigation measures, the negative consequences hit low-income households harder due to liquidity constraints and poor access to effective treatment. We recommend that malaria control policies be integrated into development and poverty reduction programs.

    This study investigated restaurant customers' perceived importance of key factors in accordance with dining occasions and restaurant segments. Our investigation into restaurant selection and situational factors present two types of empirical evidence regarding customers' choice of restaurant. First, menu price was customers' top priority in restaurant selections for full-service, quick-casual, and quick-service restaurants. Second, restaurant customers rated the importance level of restaurant selection criteria differently according to eating-out occasions. The importance of menu price was greatest for both quick meal/convenience and social occasion, brand reputation was the most important factor for business necessity, and word-of-mouth recommendation was greatest for celebration.

    Decision making in nursing is one of the most important skills nurses must apply and utilize in their nursing practice. The aim of this study was to determine the perception of clinical decision making ability among nursing students. A descriptive cross-sectional study was conducted in a tertiary hospital. A total of 54 nursing students were recruited using a modified version of Clinical Decision Making in Nursing Scale (CDMNS) adapted from Jenkins (1985). The findings showed good CDMNS score with mean and standard deviation of (124.24±12.713). The four sub-scales of CDMNS were: searching for alternative (33.24±4.821), canvassing (28.74±3.514), evaluation and re-evaluation (31.43±3.922), searching for information (30.83±4.765). Nineteen (35%) of the participants chose nursing as their first choice, whereas 35 participants (65%) did not. Thirthy seven (69%) participants were satisfied with their nursing competency, 17 (31%) were unsatisfied. There were significant differences between searching for alternatives, evaluation and re-evaluation, and nursing as their first choice (p=

    The rapidly increasing uptake of e-cigarettes in Malaysia as of late demands a study to identify factors leading to its increased popularity and user intentions to quit smoking e-cigarettes. A convenience sample of e-cigarette smokers visiting e-cigarette retail shops in Selangor and Kuala Lumpur was recruited. The majority of e-cigarette smokers were youth in colleges or universities (39 %), and young professionals and managers (36 %). The main reasons for using e-cigarettes were to help the user quit tobacco cigarettes (88 %), the perception that e-cigarettes are not as intrusive as tobacco cigarettes (85 %) and can be used in public areas (70 %), the perception that e-cigarettes are healthier than tobacco cigarettes (85 %), and its relatively lower cost compared to tobacco cigarettes (65 %). A total of 65.3 % of respondents expressed intentions to quit e-cigarettes. In a multivariate analysis, the respondents who earned monthly income of RM1000 or less were significantly more likely to intend to quit smoking e-cigarettes [OR 1.551; 95 % CI 1.022-2.355; p = 0.015] compared to the respondents who earned a monthly income of more than RM2000. The respondents who disagreed with the statement 'Smoking e-cigs is relatively cheaper compared to tobacco cigarettes' were significantly more likely to intend to quit smoking e-cigarettes [OR 1.548; 95 % CI 1.045-2.293; p = 0.027] compared to respondents who did not agree. e-cigarette preventive interventions should target areas related to the identified main reasons for using e-cigarettes, namely as an aid for quitting tobacco cigarettes, the perception that e-cigarettes are not as intrusive as tobacco cigarettes and can be used in public areas, the idea that e-cigarettes are healthier than tobacco cigarettes, and its relatively lower cost compared to tobacco cigarettes.

    MyJurnal
    Fuzzy set with similarity measure approaches are known to be effective in handling imprecise and
    subjective information to solve decision making problems. Many methods have been introduced based on these two concepts. However, most methods do not take into account the reliability factor of the imprecise information in the evaluation process. In 2010, Zadeh coined the idea of Z-number that has the ability to consider the reliability factor or the level of confidence of human’s information expression. Since then, some decision-making methods have included this concept. In this paper, we present a new fuzzy decision making procedure by integrating the Jaccard similarity measure with Z-number to solve a multi criteria decision making problem. The conversion method of the Z-number based linguistic value to trapezoidal fuzzy numbers is used and the Jaccard similarity measure of the expected intervals of trapezoidal fuzzy numbers is applied to obtain the final decision. The feasibility of the methodology is demonstrated by investigating the preference factors that could influence customers to buy their preferred choice of car. The proposed methodology is applicable to solving decision making with a fuzzy environment to achieve a reliable and optimal decision.
