    Introduction: The National Centre for Complementary and Alternative Medicine (NCCAM) defines complementary and alternative medicine (CAM) as a group of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine. Many types of CAM practices, and they may be grouped into categories such as natural products, mind–body, and body-based practices. A broad collection of own-care and practitioner-based practices, (CAM) has been a major stream health care to meet the primary health care needs of people for centuries. A good proportion of the world’s population, even in developed countries, continue to depend on CAM. This study aimed to find out the knowledge, attitude, and responses among nursing students of Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Malaysia. Methods: This cross-sectional study was carried out between June 2015 and June 2016. One hundred and eight (108) nursing studentsparticipated by simple random sampling. After taking informed consents, data were collected by structured questionnaire. The first section of survey data contained demographic profille. The second, third and fourth sections of the survey instrument consisted of the items assessing the knowledge of, interest in, and attitudes toward CAM. The last section consisted items to assess the attitude towards the teaching-and-learning in the curriculum. Descriptive statistics were used to present the data. Results: Out of 108 students, there were 19 males and 89 females. Knowledge did not have any relation (p>0.05) to response towards CAM but both positive and negative attitude was significantly (p

    The statistical characteristics of wind direction that was recorded at maximum wind speed in Peninsular Malaysia for two monsoons from 1999 to 2008 for seven stations were analyzed in this study. Modeled by von Mises distribution, the change in parameters values namely mean direction and concentration parameter was measured. Statistical summary, graphical representations, Watson-William Test and linear-circular correlation are used in the analysis. It is found that there is a significant change in the mean direction of wind over the period of ten years for most stations in Peninsular Malaysia. However, there is a weak relationship between wind direction and wind speed. This study suggested the presence of prominent direction of wind that blows in Peninsular Malaysia by monsoon. This finding may provide useful information on giving a better understanding of the behavior of the wind in Peninsular Malaysia and the potential use of wind as an alternative source of energy.

    Introduction: Students learn in many ways. Some students are visual learners, while others are auditory or kinesthetic learners. The purpose of the study is to identify the learning style of the students and factors that influence their learning styles. Methods: This is a descriptive study with cross-sectional design. Convenient sampling was used. In this study, a total of 51 nursing students were involved. A set of questionnaires using VARK (Visual; Auditory; Read/Write; Kinesthetic) inventory was used. Descriptive statistics and Chi-square test were use. Results: The learning styles of the respondents were mostly kinesthetic learning style and auditory learning styles which is 14(27.5%) for both, ten respondent had combinations of various styles, seven respondents had read write learning style and six respondent had visual learning style which is 13.7% and 11.8% respectively. Chi-square test shows that there was significant difference between learning style and respondents' demographic factors of previous school and number of siblings, where p-value 0.05). Conclusion: In order to achieve the goal of student learning it is important to use a combination of teaching methods and to make the classroom environment as stimulating and interactive as possible

    In this paper, a personal verification method using finger vein is presented. Finger vein can be considered more secured compared to other hands based biometric traits such as fingerprint and palm print because the features are inside the human body. In the proposed method, a new texture descriptor called local line binary pattern (LLBP) is utilized as feature extraction technique. The neighbourhood shape in LLBP is a straight line, unlike in local binary pattern (LBP) which is a square shape. Experimental results show that the proposed method using LLBP has better performance than the previous methods using LBP and local derivative pattern (LDP).

    This study enhanced the production of thermostable organic solvent-tolerant (TS-OST) lipase by locally isolated thermotolerant Rhizopus sp. strain using solid-state fermentation (SSF) of palm kernel cake (PKC). The optimum conditions were achieved using a series of statistical approaches. The cultivation parameters, which include fermentation time, moisture content, temperature, pH, inoculum size, various carbon and nitrogen sources, as well as other supplements, were initially screened by the definitive screening design, and one-factor-at-a-time using PKC as the basal medium. Three significant factors (olive oil concentration, pH, and inoculum size) were further optimized using face-centred central composite design. The results indicated a successful and significant improvement of lipase activity by almost two-fold compared to the initial screening production. The findings showed that the optimal conditions were 2% (v/w) inoculum size, 2% (v/w) olive oil, 0.6% (w/w) peptone, 2% (v/w) ethanol, 70% moisture content at initial pH 10.0 and 45 °C within 72 h of fermentation. Process optimization resulted in maximum lipase activity of 58.63 U/gram dry solids (gds). The analysis of variance showed that the statistical model was significant (p value <0.0001) and reliable with a high value of R2 (0.98) and adjusted R2 (0.96). This indicates a better correlation between the actual and predicted responses of lipase production. By considering this study, the low-cost PKC through SSF appears to be promising in the utilization of agro-industrial waste for TS-OST lipase production. This is because satisfactory enzyme activity could be attained that promises industrial applications.

    The Sine-Cosine algorithm (SCA) is a population-based metaheuristic algorithm utilizing sine and cosine functions to perform search. To enable the search process, SCA incorporates several search parameters. But sometimes, these parameters make the search in SCA vulnerable to local minima/maxima. To overcome this problem, a new Multi Sine-Cosine algorithm (MSCA) is proposed in this paper. MSCA utilizes multiple swarm clusters to diversify & intensify the search in-order to avoid the local minima/maxima problem. Secondly, during update MSCA also checks for better search clusters that offer convergence to global minima effectively. To assess its performance, we tested the MSCA on unimodal, multimodal and composite benchmark functions taken from the literature. Experimental results reveal that the MSCA is statistically superior with regards to convergence as compared to recent state-of-the-art metaheuristic algorithms, including the original SCA.

    INTRODUCTION AND OBJECTIVE:
    Most of important variables measured in medicine are in numerical forms or continuous in nature. New instruments and tests are constantly being developed for the purpose of measuring various variables, with the aim of providing cheaper, non-invasive, more convenient and safe methods. When a new method of measurement or instrument is invented, the quality of the instrument has to be assessed. Agreement and reliability are both important parameters in determining the quality of an instrument. This article will discuss some issues related to methods comparison study in medicine for the benefit of medical professional and researcher.

    METHOD:
    This is a narrative review and this article review the most common statistical methods used to assess agreement and reliability of medical instruments that measure the same continuous outcome. The two methods discussed in detail were the Bland-Altman Limits of Agreement, and Intra-class Correlation Coefficient (ICC). This article also discussed some issues related to method comparison studies including the application of inappropriate statistical methods, multiple statistical methods, and the strengths and weaknesses of each method. The importance of appropriate statistical method in the analysis of agreement and reliability in medicine is also highlighted in this article.

    CONCLUSION:
    There is no single perfect method to assess agreement and reliability; however researchers should be aware of the inappropriate methods that they should avoid when analysing data in method comparison studies. Inappropriate analysis will lead to invalid conclusions and thus validated instrument might not be accurate or reliable. Consequently this will affect the quality of care given to a patient.

    One species of lace bug Cochlochila bullita Stål (Heteroptera: Tingidae) was found heavily infested Orthosiphon aristatus Blume Miq., an important medicinal plant in Malaysia. A morphological re-description of C. bullita was done in order to facilitate the identification of this oligophagous insect pest. Five variables, body length and width, antenna length, tibia length and head width were measured from 15 samples from each stage. Among these variables, body length and width were used to construct the ratio for species identification; while body lengths with the other three variables were used to distinguish the nymphs from each developmental stage. The measurements of four traits except the antenna length showed significant differences between the development stages. And thus suggest the body width, tibia length and head width were suitable parameters used to distinguish the nymphal stages. However, the result on the growth factor showed only the sizes of the head followed a more constant growth rate with growth ratios (1.21-1.39) lie between the Dyar's ratio. Body length and width ratio for the adult female and male was 1.51 +/- 0.00 and 1.59 +/- 0.01, respectively. These data are pertinent for identifying developmental stages and to distinguish the species of the lace bug.

    Background and Objective: Biostatistics and epidemiology have been integral subjects in any postgraduate courses, including medical specialties Master programs. Both are widely accepted as among the difficult and confusing subjects, which worsen by lack of adequate exposure and often, time constraints. Hence, peer-led learning approach was proposed as a viable option to the traditional lecturer-driven learning style
    Method: The peer-led approach intends to promote targeted learning and conceptual understanding, instead of widely sweeping learning, which is rather directionless and could cause information overload
    Discussion: Students were divided into two groups, namely humanities-inclined group and science inclined group. Different pedagogical methods to address the different groups were discussed.
    Conclusion: This approach helps to make the learning more palatable, boosting knowledge retention and fostering camaraderie spirit among colleagues

    This study investigated the effects of stochastic facilitation in healthy subjects with normal and low auditory working memory capacity (AWMC). Forty healthy volunteers were recruited in this study. They performed a backward recall task (BRT) in quiet and under four white noise intensity levels: 45, 50, 55, and 60 dB. Brain activations during the task were measured using functional magnetic resonance imaging (fMRI). The behavioral performance in both groups increased significantly in 50 and 55 dB white noise. The normal AWMC group (mean score = 48.70) demonstrated higher activation in the superior temporal gyrus and prefrontal cortex than the low AWMC group (mean score = 30.85). However, comparisons in the brain activation between groups for all noise levels were not statistically different. The results support previous findings that stochastic facilitation enhances cognitive performance in healthy individuals. The results also proposed that brain activity among healthy subjects is more or less similar, at least in the context of auditory working memory. These findings indicated that there were no differential effects of stochastic facilitation in healthy subjects with different AWMC.

    Aims: This study aimed at exploring the self-perception of Orang Asli (OA) from the Temuan tribe in Jelebu by using the Global Self-rated Oral Health (GSROH) and General Oral Health Assessment Index (GOHAI).

    Materials and Methods: It was a cross-sectional study involving a two-stage sampling to select the district and villages. A total of 325 participants were selected based on convenience sampling.

    Results: Almost half of the participants rated their oral health as poor or average. The mean GOHAI score was 52.96 (±7.749), ranging from 29 to 60. The GOHAI score was statistically significantly lower for female gender (P = 0.025), lower education level (P = 0.001), and elderly (P = 0.001). The GSROH score was also statistically significant with GOHAI score (P = 0.001).

    Conclusions: A limited number of studies were conducted in this area, particularly in the vulnerable population of OA. Our study found that half of the OA living in the fringe had a poor GOHAI score. It is, therefore, suggested that potential study and intervention programs concentrate on the low GOHAI score group; the male, lower educational context, and the elderly.

    The practicality of biometrics of seafood cannot be overemphasized, particularly for competent authorities of the shrimp industry. However, there is a paucity of relevant literature on the relationship between biometric and physicochemical indices of freshly harvested shrimp. This work therefore investigated the relationship between biometric (standard length (SL), total weight (TW) and condition factor (CF)) and physicochemical (moisture content, pH, titratable acidity, water activity, water retention index, colour values and fracturability) characteristics of freshly harvested Pacific white shrimp (Litopenaeus vannamei) obtained from three different farms. The relationships between these parameters were determined using correlation and regression analyses.

    Introduction: Electronic medical records from hospital information system (HIS) offer a major potential for secondary data analysis which can improve the efficiency of healthcare delivery. This study describes an initiative to use HIS data to explore the level of diabetic care in patients with T2DM in a hospital-based outpatient clinic, the advantages and challenges in utilising HIS data. Methods: Patients age of 18 and above who received any diabetes medication in 2013 were retrospectively identified from HIS of Serdang Hospital. Demographic characteristics, anti-diabetic agent (ADA) dispensed, and glycaemic measures were quantified. Data was extracted using structured query lan- guage (SQL) and descriptive statistical analyses were conducted using Stata Version 12. Results: Prevalence of T2DM patients in the hospital was 7.5%. Male had slightly higher prevalence and patient at age of 61-70 years old. About 62% of patients were prescribed with metformin and 5% of newer combination of oral hypoglycemic agent. In pre- scribing pattern, stratification by age group, showed that patient age 41 to 70 years received mostly monotherapy, whilst 61.1% continue their regime for the year. Only 18% obtained good glycaemic control. Conclusion: Hospital Information system is a critical instrument in providing data as a platform in diabetic care in an outpatient care. Moving forward, steps to improve HIS should be taken to seize its potential as a tool to increase the efficiency of healthcare delivery.

    Regression is one of the basic relationship models in statistics. This paper focuses on the formation of regression models for the rice production in Malaysia by analysing the effects of paddy population, planted area, human population and domestic consumption. In this study, the data were collected from the year 1980 until 2014 from the website of the Department of Statistics Malaysia and Index Mundi. It is well known that the regression model can be solved using the least square method. Since least square problem is an unconstrained optimisation, the Conjugate Gradient (CG) was chosen to generate a solution for regression model and hence to obtain the coefficient value of independent variables. Results show that the CG methods could produce a good regression equation with acceptable Root Mean-Square Error (RMSE) value.

    University students are known to have different sleeping schedules. Students’ sleep difficulties will affect their health and their performances in studies. Sleep hygiene is a collection of healthy sleep habits that can improve one’s ability to fall asleep and stay asleep. It is considered to be imperative to treat sleep disturbance especially among university students. The aim of this study is to examine the sleep beliefs among the students of UiTM Sabah based on gender and academic performance. This study was conducted on Diploma students between March and July 2018. The respondents were randomly selected from Diploma students of all faculties in UiTM Sabah: Accounting, Business Management, Public Administration, Science, Planting Industry Management, Hotel Management, and Tourism Management. This paper is based on the Sleep Belief Scale questionnaire to assess the sleep hygiene awareness. Questionnaires were distributed using online survey. Findings of this study were analyzed using SPSS statistical software. The result of findings showed that the Sleep Incompatible Behaviours (drinking coffee, taking sleep medication, smoking before sleep) is the highest contributor of the students’ sleep hygiene and therefore it affects the sleep quality. While the Sleep Wake Cycle Behaviours (going to bed & waking up always at the same hour, going to bed two hours earlier than the habitual hour) and Thoughts and Attitude to Sleep (over thinking before sleep, trying to fall asleep without having a sleep sensation)also contributed to the sleep hygiene of the students but not as high as the Sleep Incompatible Behaviours. Based on the results of the findings, the counseling department of UiTM Sabah may organise an education program to create awareness among students about the intervention and prevention strategies as well as the incorrect beliefs about sleep.
