    Noraza RA, Norhayati NM, Rosediani M, Harmy YM
    J Taibah Univ Med Sci, 2018 Apr;13(2):188-194.
    PMID: 31435322 DOI: 10.1016/j.jtumed.2017.10.005
    Objectives: This study aimed to determine the prevalence of optimal cardiovascular disease (CVD) screening activities and the associated factors among apparently healthy school teachers.

    Methods: A cross-sectional analytical observational study was conducted among 380 secondary school teachers in Kelantan, Malaysia. A self-administered questionnaire addressing sociodemographic data and factors influencing CVD screening activities was administered. Descriptive analysis, simple and multiple logistic regression analyses were performed.

    Results: A total of 348 teachers responded to the questionnaire, with a response rate of 91.6%. The prevalence of optimal CVD screening activities was 29.3% (95% CI: 24.52, 34.08). Age, knowledge of CVD screening, family history of CVD and availability of health facilities were significantly linked to CVD screening.

    Conclusion: The prevalence of optimal screening activities was low. A great majority of the factors contributing to optimal screening were modifiable. Health care providers should widely implement global health-oriented rather than disease-orientated assessment in their daily practice.

    Active learning promotes the capacity of problem solving and decision making among learners. Teachers who apply instructional processes toward active participation of learners help their students develop higher order thinking skills. Due to the recent paradigm shift toward adopting competency-based curricula in the education of healthcare professionals in India, there is an emergent need for physiology instructors to be trained in active-learning methodologies and to acquire abilities to promote these curriculum changes. To address these issues, a series of International Union of Physiological Sciences (IUPS) workshops on physiology education techniques in four apex centers in India was organized in November 2018 and November 2019. The "hands-on" workshops presented the methodologies of case-based learning, problem-based learning, and flipped classroom; the participants were teachers of basic sciences and human and veterinary medicine. The workshop series facilitated capacity building and creation of a national network of physiology instructors interested in promoting active-learning techniques. The workshops were followed by a brainstorming meeting held to assess the outcomes. The aim of this report is to provide a model for implementing a coordinated series of workshops to support national curriculum change and to identify the organizational elements essential for conducting an effective Physiology Education workshop. The essential elements include a highly motivated core organizing team, constant dialogue between core organizing and local organizing committees, a sufficient time frame for planning and execution of the event, and opportunities to engage students at host institutions in workshop activities.

    Dehzangi A, Abdullah AM, Larki F, Hutagalung SD, Saion EB, Hamidon MN, et al.
    Nanoscale Res Lett, 2012;7(1):381.
    PMID: 22781031 DOI: 10.1186/1556-276X-7-381
    The junctionless nanowire transistor is a promising alternative for a new generation of nanotransistors. In this letter the atomic force microscopy nanolithography with two wet etching processes was implemented to fabricate simple structures as double gate and single gate junctionless silicon nanowire transistor on low doped p-type silicon-on-insulator wafer. The etching process was developed and optimized in the present work compared to our previous works. The output, transfer characteristics and drain conductance of both structures were compared. The trend for both devices found to be the same but differences in subthreshold swing, 'on/off' ratio, and threshold voltage were observed. The devices are 'on' state when performing as the pinch off devices. The positive gate voltage shows pinch off effect, while the negative gate voltage was unable to make a significant effect on drain current. The charge transmission in devices is also investigated in simple model according to a junctionless transistor principal.

    Introduction: Nursing students have been educated with critical thinking in client care. However, nursing students are often considered to be lacking in critical thinking especially during their clinical experience. This is likely due to lack of knowledge of critical thinking as the opportunities for learning critical thinking (LCT) are limited and less en- couraged to use critical thinking during the teaching and learning process. Therefore, it contributes to poor learning outcomes.The aim of this study was to identify level of LCT and critical thinking disposition (CTD) among diploma nursing student of UMS. Methods: A cross sectional survey design using purposive sampling methods. Sixty (60) of 66 year3 nursing students completed aCTD Inventory for Chinese Medical College Students (CTDI-M) by Wang et al (2019) and The LCT Inventory (LCTI) and the Teaching Critical Thinking Inventory (TCTI) developed by van Zyl, M.A., Bays, C.L., & Gilchrist, C. (2013).Approval to conduct study obtained from Dean of faculty of Medicine and Health Sciences, UMS. Results: The data were analyzed through descriptive method using SPSS for window 21.0. Total score for CTD ranging from a low (M= 1.5) to a high (M=5.00), Mean value 3.86, (SD +/- .572). Total high-level CDT 58(96.7%). Total LCT scores ranging from a low (M=2.00) to high (M=5.00) and Mean value 4.02, (SD +/- .711). Total high level LCT 54(90%). The two subscale categories were analyzed for perceived LCT. Respondents reported significantly high level of both instructor helped in LCT 51(85%) and 56 (93.3%) provides support and encourage- ment in LCT, mean value 4.19 (SD+/-.713). Conclusion: The level of CTD and LCT was high, shows that nursing students perceive themselves as having a high level of critical thinking motivation, instructor providing guidance to assist and encourage to learn using critical thinking.

    MyJurnal
    The aim of this project was to determine stress levels and to identify the main stressors that contribute to stress among Kolej Poly-Tech Mara (KPTM) nursing students during their clinical placement in order to help them overcome it. Atotal of 324 respondents undergoing training at KPTM participated in this project. The questionnaire consisting of six common stressors with 30 items using a 5-point Likert Scale was used to measure the level of stress among the respondents during their clinical placement. The data collected was examined for normal distribution, and inferential statistics such as correlations were used to seek relationships. The results indicated that the main stressors that contributed to stress among KPTM nursing students were from both environment, along with assignments and workload. There was moderate level of stress among KPTM nursing students during clinical placement and the factor that contributed to stress was due to the the possibility of making an error. Clinical placement is an essential component for nursing student's training. The practice allows nursing students the opportunity to relate the theory into practice during nursing care towards the patients. Findingsfrom this study will provide the nursing educators, clinical instructors with a meaningful understanding of the importance of clinical placement experience.

  15. Piezoresistive Effect in Plasma-Doping of Graphene Sheet for High-Performance Flexible Pressure Sensing Application
    Haniff MASM, Hafiz SM, Huang NM, Rahman SA, Wahid KAA, Syono MI, et al.
    ACS Appl Mater Interfaces, 2017 May 03;9(17):15192-15201.
    PMID: 28418234 DOI: 10.1021/acsami.7b02833
    This paper presents a straightforward plasma treatment modification of graphene with an enhanced piezoresistive effect for the realization of a high-performance pressure sensor. The changes in the graphene in terms of its morphology, structure, chemical composition, and electrical properties after the NH3/Ar plasma treatment were investigated in detail. Through a sufficient plasma treatment condition, our studies demonstrated that plasma-treated graphene sheet exhibits a significant increase in sensitivity by one order of magnitude compared to that of the unmodified graphene sheet. The plasma-doping introduced nitrogen (N) atoms inside the graphene structure and was found to play a significant role in enhancing the pressure sensing performance due to the tunneling behavior from the localized defects. The high sensitivity and good robustness demonstrated by the plasma-treated graphene sensor suggest a promising route for simple, low-cost, and ultrahigh resolution flexible sensors.

    PMID: 30595741 DOI: 10.1186/s41039-018-0081-0
    Perceived usefulness and perceived ease of use constitute important belief factors when technology adoption decisions are made within a non-mandatory setting. This paper investigated the role played by psychological ownership in shaping teachers' beliefs about using a cloud-based virtual learning environment (VLE). Psychological ownership is increasingly becoming a relevant phenomenon in technology adoption research, where people can feel psychologically attached to a particular technology. The study proposed that such phenomenon can also occur when using a VLE, and a hypothesised model with six constructs was tested with 629 Malaysian teachers from 21 schools. Results from structural equation modelling-partial least squares analysis found teachers' experiences with the VLE significantly influenced psychological ownership, which in turn significantly predicted perceived usefulness and perceived ease of use of the VLE. Overall, the model possesses predictive relevance for the outcome predictors as indicated by Stone-Geisser's Q2, and accounted for 61.6% of variance in perceived usefulness and 62.0% of variance in perceived ease of use. This study provides insights into the motivation behind teachers' beliefs which are shaped by their experiences with the VLE. Implications for theory and practice were discussed based on the insights of the study.

    Heliyon, 2020 Dec;6(12):e05733.
    PMID: 33426320 DOI: 10.1016/j.heliyon.2020.e05733
    Malaysia and many other developing countries progressively adopting massively open online course (MOOC) in their national higher education approach. We have observed an increasing need for facilitating MOOC monitoring that is associated with the rising adoption of MOOCs. Our observation suggests that recent adoption cases led analyst and instructors to focus on monitoring enrolment and learning activities. Visual analytics in MOOC support education analysts in analyzing MOOC data via interactive visualization. Existing literature on MOOC visualization focuses on enabling visual analysis on MOOC data from forum and course material. We found limited studies that investigate and characterize domain problems or design requirements of visual analytics for MOOC. This paper aims to present the empirical problem characterization and abstraction for visual analytics in MOOC learner's support monitoring. Detailed characterization and abstraction of the domain problem help visualization designer to derive design requirements in generating appropriate visualization solution. We examined the literature and conducted a case study to elicit a problem abstraction based on data, users, and tasks. We interviewed five Malaysian MOOC experts from three higher education institutes using semi-structured questions. Our case study reveals the priority of enabling MOOC analysis on learner's progression and course completion. There is an association between design and analysis priority with the pedagogical type of implemented MOOC and users. The characterized domain problems and requirements offer a design foundation for visual analytics in MOOC monitoring analysis.

  19. Fulltext New smoothed location models integrated with PCA and two types of MCA for handling large number of mixed continuous and binary variables
    Hamid, H., Ngu, P.A.H., Alipiah, F.M.
    Pertanika Journal of Science & Technology, 2018;26(1):247-260.
    MyJurnal
    The issue of classifying objects into groups when measured variables in an experiment are mixed has attracted the attention of statisticians. The Smoothed Location Model (SLM) appears to be a popular classification method to handle data containing both continuous and binary variables simultaneously. However, SLM is infeasible for a large number of binary variables due to the occurrence of numerous empty cells. Therefore, this study aims to construct new SLMs by integrating SLM with two variable extraction techniques, Principal Component Analysis (PCA) and two types of Multiple Correspondence Analysis (MCA) in order to reduce the large number of mixed variables, primarily the binary ones. The performance of the newly constructed models, namely the SLM+PCA+Indicator MCA and SLM+PCA+Burt MCA are examined based on misclassification rate. Results from simulation studies for a sample size of n=60 show that the SLM+PCA+Indicator MCA model provides perfect classification when the sizes of binary variables (b) are 5 and 10. For b=20, the SLM+PCA+Indicator MCA model produces misclassification rates of 0.3833, 0.6667 and 0.3221 for n=60, n=120 and n=180, respectively. Meanwhile, the SLM+PCA+Burt MCA model provides a perfect classification when the sizes of the binary variables are 5, 10, 15 and 20 and yields a small misclassification rate as 0.0167 when b=25. Investigations into real dataset demonstrate that both of the newly constructed models yield low misclassification rates with 0.3066 and 0.2336 respectively, in which the SLM+PCA+Burt MCA model performed the best among all the classification methods compared. The findings reveal that the two new models of SLM integrated with two variable extraction techniques can be good alternative methods for classification purposes in handling mixed variable problems, mainly when dealing with large binary variables.

  20. Fulltext In-service training and teaching resource proficiency amongst Chemistry teachers: the mediating role of teacher collaboration
    Copriady J, Zulnaidi H, Alimin M, Albeta SW
    Heliyon, 2021 May;7(5):e06995.
    PMID: 34027189 DOI: 10.1016/j.heliyon.2021.e06995
    This study aims to determine the level of collaboration, in-service training and teaching resource proficiency amongst Chemistry teachers by investigating the intermediary role of collaboration for training and teaching resources competency. A total of 184 Chemistry teachers in Riau, Indonesia, have participated in the survey. Using AMOS and SPSS 25.0 software to analyse the research data, we find a high level of collaboration, training and teaching resource proficiency amongst Chemistry teachers. Male teachers have higher proficiency level on all aspects than female teachers. The MANOVA test results show a significant difference in teacher resource competency based on gender. Male teachers are significantly more proficient than their female counterparts. However, they do not significantly differ in terms of collaboration and in-service training. The structural equation modelling test results show that collaboration has a significant role in Chemistry teachers' involvement in training and teaching resources. These research findings encourage relevant parties to design effective collaborations amongst Chemistry teachers. They also offer new insights for Chemistry teachers to keep on mastering teaching resources nationally and internationally.
