    Previous studies on instant noodles have been aimed mostly at secondary students, and have
    been concerned with the demographics, and the development of product attributes. Very few studies
    have examined the role of convenience (CO), product attributes (PA), advertising (AD) and subjective
    norms (SN) in predicting the intention of students towards the consumption of instant noodles. The
    present rising costs of living and education may affect the intention and behaviour of university students
    towards the consumption of affordable food. Therefore, the purpose of this paper was to explore the
    relationship between these variables and the variables of the Theory of Reasoned Action (TRA) in
    association with the intention of university students to consume instant noodles. A research model
    approach was used to reflect the effects of CO, PA, AD, and SN on the TRA constructs. In total, 390
    cases were gathered from three universities. Structural equation modelling was employed to assess the
    proposed research model in terms of the path significance, the general requirements for a model fit,
    and the testing of the hypotheses. It was found that AD has a direct positive effect on the behavioural
    intention of university students towards the consumption of instant noodles. Nevertheless, CO, PA, and
    SN appear to exert no significant influence on the behavioural intention of university students. The
    limitation of the study was that the findings were obtained from a small dataset covering only three
    universities. Therefore, future researches should cover a broader range of research samples. This paper
    provides additional understanding for marketing managers and researchers into the effects of CO, PA,
    AD and SN on the intention of Malaysian university students towards the consumption of instant
    noodles, which can be used for formulating marketing strategies for instant noodles and for considering
    future research directions in other countries.

    The purpose of this paper is to identify the key domains of entrepreneurial behaviour among business
    owner in food processing industry. The study utilized a deductive research design and quantitative
    method. There are twenty-one statements about entrepreneurial behaviour to discover a core action
    associated with entrepreneurial behaviour. An entrepreneurial behaviour is defined as small family
    business strategic behaviour that captures specific entrepreneurial aspects (Walker and Brown, 2004).
    In additions, it is the actions taken by the small business owner to achieve business performance
    (Delmar, 1996). According to Kirkley (2015), entrepreneurial behaviour as self determined human
    action is based on a specific set of values which the individual uses to make decisions about how to
    behave in situations that a meaningful to their business. The questionnaires focused primarily on the
    meaning of entrepreneurial behaviour as self-determination to be succeed in business. There were 70
    respondents were selected by simple random sampling. The data were analysed by Exploratory Factor
    Analysis (EFA) and categorised into relevant domains. The result shows four specific domains of
    entrepreneurial behaviour business owner in food processing industry, namely, leadership, proactiveness,
    committed and risk taking. The finding items to each of these domains are consistent with
    the small family business perspective. The practical implication is the presence of the specific core
    action associated with entrepreneurial behaviour. The business owner should employ the four core
    action to sustain the business. The result of this study is importance to academician in small business
    area, business advisor from government and non government sectors, and small family business owner.

    Sains Malaysiana, 2017;46:1565-1571.
    The rhizomes, stems and leaves of Etlingera sayapensis were extracted with ethyl acetate, acetone, ethanol and methanol to
    give 12 extracts. The total phenolic content (TPC) of the extracts was measured in this study, together with their antioxidant
    activity. Assays used were radical scavenging activity (RSA), β-carotene bleaching (BCB), ferrous ion chelating (FIC) and
    ferric reducing antioxidant power (FRAP). Among the assays, the leaf methanolic extract showed the highest activity with
    35.67 mg GAE/g (mg of gallic acid per gram of extract) for TPC, IC50 of 53.43 µg/mL for RSA, 83.24% for BCB, IC50 of
    242.43 µg/mL for FIC (second highest) and 19.53 mg TrE/g (mg of Trolox per gram of extract) for FRAP. The measured
    BCB values for the four leaf extracts were higher than those of the positive controls of butylated hydroxytoluene (BHT),
    gallic acid (GA) and ascorbic acid (AscA) and slightly lower than that of α-tocopherol (Toc). The antimicrobial activity
    of the extracts was also measured using disc-diffusion (DD) and minimum inhibition concentration (MIC) assays. Among
    the extracts, only ethanolic and methanolic extracts showed specific bacterial inhibition against Bacillus subtilis. Only
    stem methanolic extract exhibited specific fungal inhibition against Candida parapsilosis. The highest activity was shown
    by this with 9.9 mm and 1.04 mg/mL for DD and MIC assays respectively

  12. Fulltext Understanding the relationship between Kano model's customer satisfaction scores and self-stated requirements importance

    PMID: 27026893 DOI: 10.1186/s40064-016-1860-y
    Customer satisfaction is the result of product quality and viability. The place of the perceived satisfaction of users/customers for a software product cannot be neglected especially in today competitive market environment as it drives the loyalty of customers and promotes high profitability and return on investment. Therefore understanding the importance of requirements as it is associated with the satisfaction of users/customers when their requirements are met is worth the pain considering. It is necessary to know the relationship between customer satisfactions when their requirements are met (or their dissatisfaction when their requirements are unmet) and the importance of such requirement. So many works have been carried out on customer satisfaction in connection with the importance of requirements but the relationship between customer satisfaction scores (coefficients) of the Kano model and users/customers self-stated requirements importance have not been sufficiently explored. In this study, an attempt is made to unravel the underlying relationship existing between Kano model's customer satisfaction indexes and users/customers self reported requirements importance. The results of the study indicate some interesting associations between these considered variables. These bivariate associations reveal that customer satisfaction index (SI), and average satisfaction coefficient (ASC) and customer dissatisfaction index (DI) and average satisfaction coefficient (ASC) are highly correlated (r = 96 %) and thus ASC can be used in place of either SI or DI in representing customer satisfaction scores. Also, these Kano model's customer satisfaction variables (SI, DI, and ASC) are each associated with self-stated requirements importance (IMP). Further analysis indicates that the value customers or users place on requirements that are met or on features that are incorporated into a product influences the level of satisfaction such customers derive from the product. The worth of a product feature is indicated by the perceived satisfaction customers get from the inclusion of such feature in the product design and development. The satisfaction users/customers derive when a requirement is fulfilled or when a feature is placed in the product (SI or ASC) is strongly influenced by the value the users/customers place on such requirements/features when met (IMP). However, the dissatisfaction users/customers received when a requirement is not met or when a feature is not incorporated into the product (DI), even though related to self-stated requirements importance (IMP), does not have a strong effect on the importance/worth (IMP) of that given requirement/feature as perceived by the users or customers. Therefore, since customer satisfaction is proportionally related to the perceived requirements importance (worth), it is then necessary to give adequate attention to user/customer satisfying requirements (features) from elicitation to design and to the final implementation of the design. Incorporating user or customer satisfying requirements in product design is of great worth or value to the future users or customers of the product.
  13. Village midwives in Malaysia
    Peng JY, Laily N, Bakar A, Bin Marzuki A
    Stud Fam Plann, 1972 Feb;3(2):25-8.
    PMID: 4656053 DOI: 10.2307/1965087
    PIP: 292 village midwives (bidans) in Malaysia were interviewed between January 1969 and December 1970 as they came to report for training. The mean age was 47.3, 80% had had no schooling, 43% had practiced less than 10 years (32% between 10 and 20 years, 21% between 20 and 30 years, and 4% more than 30 years). On the average each bidan reported attending 3 deliveries during the past month and 26 during the past year. The average charge per delivery was about U.S.$2.00. Of 267 who responded to a question concerning other services they provided, 50% said they performed massages, 30% performed massages combined with other services, 12% said they did not do anything other than midwifery and 7% prescribed herbs and performed abortions. 67% said they first had contact with the mother during the seventh to ninth month of pregnancy, 42% between the fourth and sixth month, and 7% at or before the third month. 40% said the postpartum care lasted less than 1 week, 40% from 1-2 weeks and 19% between 2-7 weeks. Only 2 out of 198 bidans disapproved of family planning services. 99% were not worried that this would affect their job in conducting deliveries. 62% had been approached by women about family planning information services during the last 3 months. 95% thought they could help to promote the government's program by recruiting patients and distributing contraceptives. Since oral contraceptives are the most frequently used contraceptive in Malaysia, bidans could resupply the women with the pill. They could play an important role in promoting contraceptive continuation in rural areas by providing women with a continuous motivation through their constant contact. The success of using bidans in rural family planning services will greatly depend on their supervision. They can be paid with a flat salary-type payment, with an incentive scheme alone, or a combination of the two.
  14. Fulltext Chemical composition, antioxidant, and antibacterial activity of essential oils from Etlingera sayapensis A.D. Poulsen & Ibrahim
    Mahdavi B, Yaacob WA, Din LB
    Asian Pac J Trop Med, 2017 Aug;10(8):819-826.
    PMID: 28942832 DOI: 10.1016/j.apjtm.2017.08.006
    OBJECTIVE: To report the chemical composition and bioactivity (including antioxidant and antimicrobial activity) of essential oils from the rhizomes, stems, and leaves of Etlingera sayapensis (E. sayapensis) A.D. Poulsen & Ibrahim for the first time.

    METHODS: First, the essential oils were obtained using a Clevenger-type apparatus. Then, the essential oils compositions were identified by chromatography methods including GC-FID and GC-MS. For the next step, DPPH radical scavenging activity (RSA), β-carotene bleaching (BCB), and ferrous ion chelating ability (FIC) were chosen to evaluate the essential oils antioxidant activity. Finally, disc diffusion assay and minimum inhibitory concentration method (MIC) was applied to investigate antimicrobial activity of the rhizomes and leaves oils of E. sayapensis against 18 microorganisms.

    RESULTS: All of the oils contained oxygenated monoterpenes (leaves: 74.18%, stems: 75.60%, and rhizome: 54.61%), The essential oil obtained from leaves contained high amount of carvone (21.38%), cis-carveol (13.49%); The rhizomes oil was rich in linalool formate (25.47%), eugenol (11.84%); and the stems oil was dominated by α-terpineol (39.86%), linalool formate (30.55%). The leaves oil represented the highest ability in all of the antioxidant activity tests. For antimicrobial activity, the rhizome oil presented more active when compared to leaves oil against Bacillus subtilis, Bacillus thuringiensis, Staphylococcus aureus, methicillin resistant Staphylococcus aureus (MRSA), Aeromonas hydrophila, Escherichia coli, Enterobacter aerogenes, Proteus mirabilis, Shigella sonnei, Serratia marcescens, Vibrio parahaemolyticus, Candida albicans, and Candida parapsilosis.

    CONCLUSIONS: The most components of the essential oils belong to oxygenated monoterpenes. Linalool formate, carvone, and α-terpineol are found as the most abundant compounds in the oils of the different parts of E. sayapensis. The rhizomes oil can prevent the growth of wide spectrum microorganisms; however, the oils are not highly potent in antioxidant assays.

    Health risk factors have been highlighted among Nigerian students at Universiti Putra Malaysia, but the pattern of food expenditure on diets that are said to be a control measure for the prevalence of risk factors such as chronic diseases, obesity, diabetes, and hypertension has been poorly discussed. The purpose of this paper is to examine food expenditure on diets and its relationship to health risk factors among Nigerian students in Universiti Putra Malaysia. Cross-sectional research design was used and data for the study was obtained using structured questionnaire. A total of 236 Nigerian students’ participants from Universiti Putra Malaysia aged 25-45 years consented to participate in this study and 233 were selected through systematic random sampling. Health conditions and personal risk factors were measured with the Institute for Public Health (2015) of National Health and Morbidity Survey (NHMS, 2011) questionnaire. The Center for Disease Control and Prevention (CDC); National Health and Nutrition Examination Survey (NHANES 2007-2008) of Flexible Consumer Behavior Survey (FCBS) on food expenditure questionnaire was used in measuring all food and beverages spending of respondents for the period of 30 days. The data collected was cleaned and entered into a database and analyzed using SPSS version 20. Descriptive analyses for continuous data were expressed in mean and standard deviation while categorical data were presented in percentage. Pearson correlation analyses were used to examine the relationship between food expenditure on diets and health risk factors. The findings of the study showed that 67% were males and 33% females. The association between health risk factors and food expenditure were positively weak, but significant r = 0.14, (231), p < 0.05. The findings suggested that an increase in food expenditure pattern on diets was significantly associated with a minimal increase in health risk factors. For an average student food expenditure on diets, this can lead to a real obstacle to healthy eating. The findings provided recommendations for food expenditure on diets and health risk factors interventions and policies aimed at University students.

    Khong HY, Laily B Din, Norzamzurina Ismail, Mohd Ambar Yarmo, Zuriati Zakaria, Nor Hadiani Ismail
    Sains Malaysiana, 2013;42:943-948.
    A qualitative analysis of the individual compounds in Litsea fulva (locally known as ‘Medang’) essential oils was performed by comprehensive two-dimensional gas chromatography (GC × GC) coupled with time-of-flight mass spectrometer (TOF/MS) for the identification of the resolved peaks. Litsea fulva essential oil was found to contain 98 identifiable peaks with 32 compounds were identified with good matches. These compounds identified included 30 hydrocarbons, 22 alcohols, five acids, 16 ketones, five aldehydes, 12 esters, six ethers and two other compounds. The L. fulva leaf oil contained alcohols and ethers, with 34.09% and 24.38%, respectively. The major components of these oils were cis-Z-α-bisabolene epoxide (9.51%), trans-Z-α-bisabolene epoxide (8.36%), C13H20O2 (7.39%), longipinocarvone (5.68%), τ-Cadinol (4.24%), C15H24O (4.98%) and α-cadinol (3.95%). The study also showed that the comprehensive two-dimensional gas chromatography (GC × GC) is a better and more powerful separation tool in GC and an identification tool for analyzing complex volatile oils compared with the one-dimensional GC.
