    Knowledge Management (KM) addresses the critical issues of organizational adoption, survival and competence in the face of an increasingly changing environment. KM embodies organizational processes that seek a synergistic combination of the data and information processing capabilities of information and communication technologies (ICT), and the creative and innovative capacity of human beings to improve ICT In that role, knowledge management will improve quality management and avoid or minimize losses and weakness that usually come from poor performance as well as increase the competitive level of the company and its ability to survive in the global marketplace. To achieve quality, all parties including the clients, company consultants, contractors, entrepreneurs, suppliers, and the governing bodies (i.e., all involved stake-holders) need to collaborate and commit to achieving quality. The design based organizations in major business and construction companies have to be quality driven to support healthy growth in today's competitive market. In the march towards vision 2020 and globalization (i.e., the one world community) of many companies, their design based organizations need to have superior quality management and knowledge management to anticipate changes. The implementation of a quality system such as the ISO 9000 Standards, Total Quality Management, or Quality Function Deployment (QFD) focuses the company's resources towards achieving faster and better results in the global market with less cost. To anticipate the needs of the marketplace and clients as the world and technology change, a new system, which we call Power Quality System (PQS), has been designed. PQS is a combination of information and communication technologies (ICT) and the creative and innovative capacity of human beings to meet the challenges of the new world business and to develop high quality products.

    Teachers face one of the highest demands of any professional group to use their voices at work. Thus, they are at
    higher risk of developing voice disorder than the general population. The consequences of voice disorder may have
    impact on teacher’s social and professional life as well as their mental, physical and emotional state and their
    ability to communicate. Objectives of this study are to determine the prevalence of voice disorder and the
    relationship between voice disorder with associated risk factors such as teaching activities and lifestyle factors
    among primary school teachers in Bintulu, Sarawak. A cross sectional study was conducted based on random sample
    of 4 primary schools in Bintulu, Sarawak between January-March 2014. A total of 100 full-time primary school
    teachers were invited to participate in the study. Data were collected through a self-administered questionnaire
    addressing the prevalence of voice disorder and potential risk factors. Descriptive analysis and chi-square test was
    used to measure the relationship between voice disorder and associated risk factors. The response rate for this study
    was 78% (78/100). The study found that the prevalence of voice disorder among primary school teachers in Bintulu,
    Sarawak was 13%. Chi-square test results revealed that factors significantly associated with voice disorder (p

    The toxicities of ROUNDUP and its component chemicals, glyphosate (N-phosphonomethylglycine) and polyoxyethyleneamine (POEA), were determined at 0, 1, 3, 6 and 24 h following administration to rats. The intratracheal administration of glyphosate (0.2 g/kg), POEA (0.1 g/kg), a mixture of glyphosate (0.2 g/kg) + POEA (0.1 g/kg), or ROUNDUP (containing 0.2 g/kg glyphosate and 0.1 g/kg POEA) elicited immediate respiratory effects which were more severe and which lasted longer in the groups receiving the POEA-containing preparations than in the glyphosate alone group. By 1 h, all test preparations had caused deaths, but more occurred from the POEA-containing preparations than from glyphosate. The po administration of POEA (1 g/kg), the mixture of glyphosate (2 g/kg) +POEA (1 g/kg), or ROUNDUP (containing 2 g/kg glyphosate and 1 g/kg POEA) produced diarrhea and blood-stained weeping from noses. Death was only seen from POEA at 24 h. Glyphosate (2 g/kg po) produced transient diarrhea without nose bleeds; POEA caused diarrhea at 1 h; and the mixture of POEA + glyphosate produced diarrhea later that increased in severity with time. Bloody nose secretions were seen only with the preparations that contained POEA. No deaths, respiratory effects or bloody nose secretions occurred in controls given saline. Both POEA and glyphosate caused lung hemorrhages and lung epithelial cell damage with po or intratracheal exposures. These results indicate POEA and preparations that contained POEA were more toxic than glyphosate.

    Worsening climatic conditions can subsequently lead to the frequent occurrence of unpredictable natural disasters. The early-life educational approach is one of the non-structural mitigations in disaster management, which are the most effective efforts to promote early-life disaster awareness and enhance the knowledge transfer in disaster risk education. By using the health belief model (HBM), this study aims to examine the effectiveness of HBM on the flood-risk reduction (FRR) educational intervention by looking into the perceived susceptibility, severity, benefit and self-efficacy among elementary school children in Malaysia. This study utilised the one-group pre-test-post-test design by recruiting 224 elementary school children in the pre-FRR educational intervention programme, and 205 who undertook a post-intervention programme a month later. This study showed that the FRR educational intervention significantly improved (p < 0.001) the overall HBM components during the post-intervention, particularly in: (1) FRR knowledge, (2) perceived susceptibility, (3) perceived severity and (4) perceived benefits. The one-way analysis of covariance test showed that knowledge transfer intervention is effective to improve all the HBM components that include (1) FRR knowledge, F(38,127) = 2.517; (2) perceived susceptibility, F(6,191) = 6.957; (3) perceived severity, F(20,163) = 2.944; (4) perceived benefits, F(25,153) = 2.342 and (5) self-efficacy, F(7,189) = 12.526. The impact of integrating HBM into knowledge transfer intervention was seen to be effective and provide a positive knowledge enhancement among learners. Therefore, it is crucial to implement a consistent and sustainable educational intervention to harness formal education for community resilience at an early age.

    BACKGROUND: Knowledge of hepatitis B and C has been reported to be low among respondents in different studies. We conducted a cross-sectional study among international students of Universiti Putra Malaysia (UPM) to ascertain their levels of knowledge, attitude and practices regarding hepatitis B and C and its associated factors.

    METHODS: Six hundred and sixty two (662) international students participated in this study. A cluster sampling method was employed and data was generated using self-administered questionnaire, which was validated and its reliability checked.

    RESULTS: Normality test was conducted followed by descriptive statistics, spearman's correlation and Chi-square tests to explore associations between variables in the study. The response rate was 71.49 %. Of these, 50.3 % of the respondents had better knowledge of hepatitis B; 52.7 % had better knowledge of hepatitis C; 54.8 % had positive attitude towards hepatitis B and C and 77.6 % had safer practices towards hepatitis B and C. Positive correlations were found between knowledge of hepatitis B and knowledge of hepatitis C; knowledge hepatitis B and attitude; knowledge hepatitis C and attitude; knowledge hepatitis B and practice; knowledge hepatitis C and practice; and attitude and practice regarding hepatitis B and C. Similarly, some socio-demographic variables and history of hepatitis were found to be associated with knowledge, attitude and practice related to hepatitis B and C.

    CONCLUSION: The levels of knowledge and attitude towards hepatitis B and C were low among respondents but majority of them exhibited safe practices. The study level, faculty, age, nationality, marital status and gender of the respondents were significantly associated with their levels of knowledge, attitude and practices towards the disease. These findings imply that there is need for hepatitis health promotion among the international students of UPM and possibly other international students across the globe. It will serve to improve their levels of knowledge, attitude and practices in short term and get them protected against the disease in the long run.

    Breast cancer is the most common cancer spread among women worldwide. Whereas many studies have discussed the significance of breast cancer screening among women in various countries, few have attempted to discuss this topic among female school teachers. As teachers educate and communicate with students, this may play an essential role in health education and in promoting healthy behavior, such as breast cancer screening. The primary goal of this study is to develop and implement an educational intervention of breast cancer screening and evaluate its effectiveness among Yemeni female school teachers in Malaysia. This was carried out as per the health belief model. A cluster-randomized controlled trial was conducted among 183 Yemeni female school teachers in twelve schools in Klang Valley, Malaysia. A random assignment of the target schools was made to include them within the intervention or control group. Participants in the intervention group were offered a 90-minute session for one-day educational intervention on breast cancer screening. On the other hand, participants in the control group were offered the same educational materials at the end of the study. Relevant data was collected at baseline, one month following the intervention, and then three- and six-months follow-up assessments. Analysis of such data was done via IBM SPSS software 25.0 by generalized estimating equations (GEE) to assess the differential changes over time. A primary outcome embodied in breast cancer screening practice uptake was expected. Secondary outcomes include the target group's knowledge on and beliefs of breast cancer screening. This study intends to contribute to the credibility and effectiveness of utilizing a theory-based breast cancer screening intervention in order to raise the awareness of women on conducting breast cancer screening.

    Introduction: About 18% of Malaysian Armed Forces (MAF) personnel are diagnosed with either hypertension, diabetes or coronary artery disease, while another 8% are obese. The rising prevalence necessitates intervention.
    Methods: This is a single blinded randomized controlled trial among overweight and obese MAF personnel attending medical checkup in MAF hospital in Kuala Lumpur. An intervention module was developed to increase their physical activity level. Short version of International Physical Activity Questionnaire was used to assess physical activity in metabolic equivalent of task score (METs score), while blood pressure, body mass index (BMI), blood lipid profile and fasting blood sugar measurements were also obtained. These parameters were measured at baseline and again at 6 months. Generalized estimating equations (GEE) statistical test were applied to evaluate the effect of the intervention.
    Results: Response rate was 100%. Most of participants were aged above 40 years, male, from Malay ethnic group, completed secondary education and had monthly income above RM 4000. Most of the respondents were obese and had moderate level of physical activity at baseline. All variables compared between groups at baseline showed no significant difference. At six months, after controlling for covariates, the significant difference was only in METs score. The odds of having high METs score in the intervention group after receiving intervention was nearly 3 times higher than those in the control group, after adjusting for interaction between time and group as well as other covari- ates (AOR = 2.908, 95% CI 1.323 – 6.391, P=0.008).
    Conclusion: Intervention was effective in increasing physical activity among overweight and obese military personnel.

    (1) Background: Substance use among inner-city adolescents is at an alarming rate in Nigeria. Despite their high exposure to this risk, limited experimental tests have been conducted on prevention programs. (2) Methods: This study investigates the effectiveness of an empowerment education intervention in reducing the risk of substance use in Abuja's inner-city adolescents. Random selection placed adolescents into intervention and control conditions, and assessment was conducted at baseline, post-test, and 3-months follow-up intervention. After pre-test, the intervention group engaged in an empowerment education intervention of 11 sessions. (3) Results: In a post-test of three months, results show significant and positive changes among adolescents in substance use, including a notable reduction in positive attitudes toward drugs. In other words, the results showed adolescents reported less depression and substance use as well as higher peer support, parental support, social competence, and self-esteem at post-test and 3-month follow-ups as compared to the pre-intervention period. In addition, at both post-test and the 3-month follow-up, the intervention group performed better than the control group on peer support, parental support, social competence, and self-esteem. (4) Conclusions: This study presents a new indication that the empowerment education intervention effectively reduces substance use among Nigeria's inner-city adolescents.

    There is a high rate of unintended pregnancies in Malaysia due to low contraceptive use. Only 30% of married women use modern contraceptive methods. Emergency contraception (EC) is used within a few days of unprotected sex to prevent pregnancy. The purpose of this study was to investigate the knowledge, attitudes, and practices regarding EC pill use among Malay women. A cross sectional study was conducted among married female staff using stratified random sampling from 15 faculties in the Universiti Putra Malaysia (UPM). Data about sociodemographic factors, reproductive health, knowledge, attitudes and practices regarding EC use were gathered using validated self-administered questionnaire. The response rate was 87%. Half the 294 subjects who participated had a low knowledge, 33.0% a moderate knowledge and 17.0% a good knowledge about the EC pill. Eighty-eight percent of respondents had a positive attitude and 12.0% a negative attitude toward EC. Eleven percent of respondents had previously used EC. Unplanned and unwanted pregnancies were reported by 35.0% and 14.0% of respondents, respectively. Most respondents lacked knowledge about the indications for using EC, its mechanism of action, when it can be used and its side effects. Our findings show a need to educate women about EC.

    Family planning has been cited as essential to the achievement of Millennium Development Goals (MDG). Family planning has a direct impact on women's health and consequence of each pregnancy. The use of modern contraception among Asian women is less than global average. In Asia a majority of unintended pregnancies are due to using traditional contraceptive or no methods which lead to induced unsafe abortion. Cultural attitudes, lack of knowledge of methods and reproduction, socio demographic factors, and health service barriers are the main obstacles to modern contraceptive practice among Asian women. Culturally sensitive family planning program, reforming health system, and reproductive health education through mass media to create awareness of the benefits of planned parenthood are effective strategies to improve modern contraceptive practice among Asian women.

    The objective of this study was to investigate the angiogenic potential of human chorion-derived stem cells (CDSC) cultured in medium containing bFGF and VEGF (EDM50). Total RNA was extracted from cells cultured in FD+10% FBS and EDM50. Quantitative RT-PCR was carried out to score the differential mRNA expression of genes involve in angiogenesis and endothelial differentiation. Our finding demonstrated that all angiogenic and endothelial associated genes were expressed higher in EDM50. Expression level of ANG-1, eNOS and VEGFR2 were significantly higher in EDM50 compared to FD+10% FBS. Our results suggested that human CDSC cultured in EDM50 can be used for angiogenesis purpose in regenerative medicine.

    The aim of the study is to evaluate the stemness gene expression of cultured human amniotic epithelial cells (HAECs) in serial passages. HAECs obtained from human term placentae were cultured in F12:DMEM(1:1) + 10% FBS +10ng/ml EGF in serial passages (P0, P1, P2 and P4). Quantitative RT-PCR was used to assess the gene expression analysis. The results showed that cultured HAECs expressed and downregulated the stemness genes expression for Oct-4, Sox-2, Nanog3, FGF4, Rex-1, FZD-9, BST-1 ABCG2. However, vimentin and nestin gene expression were upregulated. The results suggested that cultured HAECs may have pluripotent and multipotent properties.

    The aim of the study is to determine the neuronal and glial gene expression of cultured human amniotic epithelial cells (HAECs) in serial passages. HAECs obtained from human term placentae were cultured in F12:DMEM (1:1) + 10% FBS +10ng/ml EGF in serial passages. Quantitative RT-PCR was used to assess the gene expression analysis. The results showed that the cultured HAECs expressed the neural stem cell genes (Nestin, NSE and Vimentin), mature neuronal genes (TH, MAP-2, beta-III-tubulin and NFM) and glial genes (CNPase, MBP and Olig). These neural stem cell genes increased with serial passages while the genes expression for mature neuronal and glial cells were downregulated. These results suggested that HAECs may promote or involve in neurogenesis and gliagenesis.

    Angiogenic induction was made to promote angiogenesis by differentiating stem cells towards endothelial cells. However, the stemness property of induced cells has not been revealed yet. Hence, we aim to evaluate the differential mRNA expression of stemness genes in human chorion-derived stem cells (CDSC) after being cultured in EDM50 comprised bFGF and VEGF. Results indicated that CDSC cultured in EMD50 expressed significantly higher mRNA level of Sox-2, FZD9, BST-1 and Nestin. In addition Oct-4, FGF-4 and ABCG-2 were also upregulated. Our finding suggested that CDSC after angiogenic induction enhanced its stem cell properties. This could be contributed for the mechanism of stem cell therapy in ischemic problem.

    BACKGROUND:
    The main sexual and reproductive health issues among young people are premarital sexual intercourse, unwanted pregnancies, unsafe abortions and sexually transmitted diseases including Human Immunodeficiency Virus. The aim of this study was to determine the knowledge related to sexual and reproductive health among Malaysian postgraduate students in a public university in Malaysia.

    METHODS:
    A cross-sectional study was carried out among postgraduate students by systematic random sampling technique. A pre-tested self administered questionnaire was used to collect the data.

    RESULTS:
    Out of 434 respondents, the majority of students were female (78.6 %) and single (78.3 %). The overall mean age of respondents was 27.0 ranging from 20 to 46 years of age. The main sources of information for sexual and reproductive health awareness were the internet (78.6 %) and newspaper (61.8 %). The majority (97.9 %) of the students knew that AIDS is a sexually transmitted disease. Most of them believed that the spread of sexually transmitted diseases was through shaking hands (92.1 %). Use of condoms was perceived to be the best way to avoid sexually transmitted diseases (88.4 %). Sexual and reproductive health knowledge was significantly associated with the students' age, marital status and faculty. The socio-demographic factors and current educational status accounted for a significant 9 % of the variability in sexual and reproductive health knowledge, f (7, 426) = 11, p <0.001.

    CONCLUSIONS:
    The postgraduate students' level of knowledge on sexual and reproductive health was not satisfactory. Sexual and reproductive health knowledge was associated with the students' marital status and faculty. Intervention programs related to sexual and reproductive health are recommended.

    There have been various systematic reviews on the significance of educational interventions as necessary components to encourage breast cancer screening (BCS) and reduce the burden of breast cancer (BC). However, only a few studies have attempted to examine these educational interventions comprehensively. This review paper aimed to systematically evaluate the effectiveness of various educational interventions in improving BCS uptake, knowledge, and beliefs among women in different parts of the world. Following the PRISMA guidelines, a comprehensive literature search on four electronic databases, specifically PubMed, Scopus, Web of Science, and ScienceDirect, was performed in May 2019. A total of 22 interventional studies were reviewed. Theory- and language-based multiple intervention strategies, which were mainly performed in community and healthcare settings, were the commonly shared characteristics of the educational interventions. Most of these studies on the effectiveness of interventions showed favorable outcomes in terms of the BCS uptake, knowledge, and beliefs among women. Educational interventions potentially increase BCS among women. The interpretation of the reported findings should be treated with caution due to the heterogeneity of the studies in terms of the characteristics of the participants, research designs, intervention strategies, and outcome measures.
