    Chen LL, Mat Ludin AF, Shahar S, Manaf ZA, Tohit NM
    Syst Rev, 2020 Nov 23;9(1):265.
    PMID: 33228765 DOI: 10.1186/s13643-020-01517-0
    BACKGROUND: The prevalence of type-2 diabetes mellitus (T2DM) has been increasing globally. Without proper management, T2DM can develop into serious complications and even death. Diet modification is one of the most effective tools in managing T2DM at the early stage, but it requires knowledge and compliance from the patients. Thus, meal replacement (MR) has gained its popularity as a tool for diet modification to improve glycemic control and also reducing weight in T2DM patients. There are several existing meal replacement studies but not much is known on the general scope and effect of these existing MRs. Hence, this review is aimed to provide an overview of the existing evidences regarding the application of meal replacement on T2DM patients and identify the gaps or limitations in the studies.

    METHODOLOGY: The scoping review will be carried out in six stages: (1) identifying the research question, (2) identifying relevant studies through electronic databases (i.e., PubMed, Scopus, Cochrane Reviews, Google Scholar, EBSCOHOST, Science Direct) and also gray literature, and (3) selection of studies to be included based on inclusion criteria. Search and initial screening of studies to be included will be conducted by two independent reviewers. Discrepancies will then be solved through discussion with other reviewers; (4) charting and categorizing extracted data in a pretested data extraction form; (5) collating, summarizing, and reporting the results; and lastly, (6) conducting consultation with stakeholders and experts in diabetes.

    DISCUSSION: This scoping review protocol is aimed to provide a framework enabling us to map and summarize the findings from existing studies involving meal replacement. It will help researchers to identify the research gap and provide recommendations for future meal replacement studies. The results from this scoping review will be useful to various stakeholders in healthcare. It is also part of a research project in which the information obtained will be utilized in a clinical trial of a developed meal replacement plan. Dissemination of knowledge will also be done through presentations at related scientific conferences.

  2. Fulltext Luminescent measurement systems for the investigation of a scramjet inlet-isolator
    Idris AC, Saad MR, Zare-Behtash H, Kontis K
    Sensors (Basel), 2014;14(4):6606-32.
    PMID: 24721773 DOI: 10.3390/s140406606
    Scramjets have become a main focus of study for many researchers, due to their application as propulsive devices in hypersonic flight. This entails a detailed understanding of the fluid mechanics involved to be able to design and operate these engines with maximum efficiency even at their off-design conditions. It is the objective of the present cold-flow investigation to study and analyse experimentally the mechanics of the fluid structures encountered within a generic scramjet inlet at M = 5. Traditionally, researchers have to rely on stream-thrust analysis, which requires the complex setup of a mass flow meter, a force balance and a heat transducer in order to measure inlet-isolator performance. Alternatively, the pitot rake could be positioned at inlet-isolator exit plane, but this method is intrusive to the flow, and the number of pitot tubes is limited by the model size constraint. Thus, this urgent need for a better flow diagnostics method is addressed in this paper. Pressure-sensitive paint (PSP) has been applied to investigate the flow characteristics on the compression ramp, isolator surface and isolator sidewall. Numerous shock-shock interactions, corner and shoulder separation regions, as well as shock trains were captured by the luminescent system. The performance of the scramjet inlet-isolator has been shown to improve when operated in a modest angle of attack.

  3. Fulltext Improvement in sensitivity of an inductive oil palm fruit sensor
    Misron N, Harun NH, Lee YK, Sidek RM, Aris I, Wakiwaka H, et al.
    Sensors (Basel), 2014;14(2):2431-48.
    PMID: 24496313 DOI: 10.3390/s140202431
    Among palm oil millers, the ripeness of oil palm Fresh Fruit Bunch (FFB) is determined through visual inspection. To increase the productivity of the millers, many researchers have proposed with a new detection method to replace the conventional one. The sensitivity of such a sensor plays a crucial role in determining the effectiveness of the method. In our preliminary study a novel oil palm fruit sensor to detect the maturity of oil palm fruit bunches is proposed. The design of the proposed air coil sensor based on an inductive sensor is further investigated to improve its sensitivity. This paper investigates the results pertaining to the effects of the air coil structure of an oil palm fruit sensor, taking consideration of the used copper wire diameter ranging from 0.10 mm to 0.18 mm with 60 turns. The flat-type shape of air coil was used on twenty samples of fruitlets from two categories, namely ripe and unripe. Samples are tested with frequencies ranging from 20 Hz to 120 MHz. The sensitivity of the sensor between air to fruitlet samples increases as the coil diameter increases. As for the sensitivity differences between ripe and unripe samples, the 5 mm air coil length with the 0.12 mm coil diameter provides the highest percentage difference between samples and it is amongst the highest deviation value between samples. The result from this study is important to improve the sensitivity of the inductive oil palm fruit sensor mainly with regards to the design of the air coil structure. The efficiency of the sensor to determine the maturity of the oil palm FFB and the ripening process of the fruitlet could further be enhanced.

    Rifai D, Abdalla AN, Ali K, Razali R
    Sensors (Basel), 2016;16(3):298.
    PMID: 26927123 DOI: 10.3390/s16030298
    Non-destructive eddy current testing (ECT) is widely used to examine structural defects in ferromagnetic pipe in the oil and gas industry. Implementation of giant magnetoresistance (GMR) sensors as magnetic field sensors to detect the changes of magnetic field continuity have increased the sensitivity of eddy current techniques in detecting the material defect profile. However, not many researchers have described in detail the structure and issues of GMR sensors and their application in eddy current techniques for nondestructive testing. This paper will describe the implementation of GMR sensors in non-destructive testing eddy current testing. The first part of this paper will describe the structure and principles of GMR sensors. The second part outlines the principles and types of eddy current testing probe that have been studied and developed by previous researchers. The influence of various parameters on the GMR measurement and a factor affecting in eddy current testing will be described in detail in the third part of this paper. Finally, this paper will discuss the limitations of coil probe and compensation techniques that researchers have applied in eddy current testing probes. A comprehensive review of previous studies on the application of GMR sensors in non-destructive eddy current testing also be given at the end of this paper.

    Khan A, Ali I, Ghani A, Khan N, Alsaqer M, Rahman AU, et al.
    Sensors (Basel), 2018 May 18;18(5).
    PMID: 29783686 DOI: 10.3390/s18051619
    Recent research in underwater wireless sensor networks (UWSNs) has gained the attention of researchers in academia and industry for a number of applications. They include disaster and earthquake prediction, water quality and environment monitoring, leakage and mine detection, military surveillance and underwater navigation. However, the aquatic medium is associated with a number of limitations and challenges: long multipath delay, high interference and noise, harsh environment, low bandwidth and limited battery life of the sensor nodes. These challenges demand research techniques and strategies to be overcome in an efficient and effective fashion. The design of routing protocols for UWSNs is one of the promising solutions to cope with these challenges. This paper presents a survey of the routing protocols for UWSNs. For the ease of description, the addressed routing protocols are classified into two groups: localization-based and localization-free protocols. These groups are further subdivided according to the problems they address or the major parameters they consider during routing. Unlike the existing surveys, this survey considers only the latest and state-of-the-art routing protocols. In addition, every protocol is described in terms of its routing strategy and the problem it addresses and solves. The merit(s) of each protocol is (are) highlighted along with the cost. A description of the protocols in this fashion has a number of advantages for researchers, as compared to the existing surveys. Firstly, the description of the routing strategy of each protocol makes its routing operation easily understandable. Secondly, the demerit(s) of a protocol provides (provide) insight into overcoming its flaw(s) in future investigation. This, in turn, leads to the foundation of new protocols that are more intelligent, robust and efficient with respect to the desired parameters. Thirdly, a protocol can be selected for the appropriate application based on its described merit(s). Finally, open challenges and research directions are presented for future investigation.

    PMID: 36616745 DOI: 10.3390/s23010146
    Augmented reality (AR) has gained enormous popularity and acceptance in the past few years. AR is indeed a combination of different immersive experiences and solutions that serve as integrated components to assemble and accelerate the augmented reality phenomena as a workable and marvelous adaptive solution for many realms. These solutions of AR include tracking as a means for keeping track of the point of reference to make virtual objects visible in a real scene. Similarly, display technologies combine the virtual and real world with the user's eye. Authoring tools provide platforms to develop AR applications by providing access to low-level libraries. The libraries can thereafter interact with the hardware of tracking sensors, cameras, and other technologies. In addition to this, advances in distributed computing and collaborative augmented reality also need stable solutions. The various participants can collaborate in an AR setting. The authors of this research have explored many solutions in this regard and present a comprehensive review to aid in doing research and improving different business transformations. However, during the course of this study, we identified that there is a lack of security solutions in various areas of collaborative AR (CAR), specifically in the area of distributed trust management in CAR. This research study also proposed a trusted CAR architecture with a use-case of tourism that can be used as a model for researchers with an interest in making secure AR-based remote communication sessions.

    Menezes RG, Kharoshah MA, Madadin M, Marakala V, Lasrado S, Al Tamimi DM
    Sci Eng Ethics, 2016 12;22(6):1843-1847.
    PMID: 26670920 DOI: 10.1007/s11948-015-9742-1
    This article seeks to address and dispel some of the popular myths and misconceptions surrounding authorship of a scientific publication as this is often misconstrued by beginners in academia especially those in the developing world. While ethical issues in publishing related to authorship have been increasingly discussed, not much has been written about the myths and misconceptions of who might be an author. Dispelling these myths and misconceptions would go a long way in shaping the thoughts and plans of students, junior faculty and researchers in academia especially in the developing world.

    Olesen AP, Amin L, Mahadi Z
    Sci Eng Ethics, 2019 08;25(4):1111-1124.
    PMID: 29717467 DOI: 10.1007/s11948-018-0054-0
    The purpose of this study is to encourage and highlight discussion on how to improve the teaching of research ethics in institutions of higher education in Malaysia. Drawing on semi-structured interviews with 21 academics in a research-intensive university in Malaysia, interviewees agreed on the importance of emphasizing the subject of research ethics among students, as well as academics or researchers. This study reveals that participants felt that there is an urgent need to improve the current awareness and knowledge of issues related to misconduct in research among students and academics. The results of this study indicate a need for better teaching on the subject of research ethics in order to prevent misconduct in research. Finally, it concludes with suggestions that there should be a clear definition of research misconduct, to include consequences when engaging in misconduct; a separate research ethics syllabus for pure and social sciences should be conducted; research ethics should be implemented as a core subject, and there should be an early intervention and continuous learning of research ethics, with an emphasis on ethics training.

  11. In Their Own Words: Research Misconduct from the Perspective of Researchers in Malaysian Universities
    Olesen AP, Amin L, Mahadi Z
    Sci Eng Ethics, 2018 12;24(6):1755-1776.
    PMID: 29249021 DOI: 10.1007/s11948-017-9997-9
    Published data and studies on research misconduct, which focuses on researchers in Malaysia, is still lacking, therefore, we decided that this was an area for investigation. This study provides qualitative results for the examined issues through series of in-depth interviews with 21 researchers and lecturers in various universities in Malaysia. The aims of this study were to investigate the researchers' opinions and perceptions regarding what they considered to be research misconduct, their experience with such misconduct, and the factors that contribute to research misconduct. Our findings suggest that the most common research misconducts that are currently being witnessed in Malaysian universities are plagiarism and authorship disputes, however, researchers seldom report incidents of research misconduct because it takes too much time, effort and work to report them, and some are just afraid of repercussions when they do report it. This suggests possible loopholes in the monitoring system, which may allow some researchers to bypass it and engage in misconduct. This study also highlights the structural and individual factors as the most influential factors when it comes to research misconduct besides organizational, situational and cultural factors. Finally, this study highlights the concerns of all participants regarding the 'publish or perish' pressure that they believe would lead to a hostile working environment, thus enhancing research misconduct, as researchers tend to think about their own performance rather than that of whole team or faculty. Consequently this weakens the interpersonal relationships among researchers, which may compromise the teaching and supervision of junior researchers and research students.

  12. Promoting Ethics and Integrity in Management Academic Research: Retraction Initiative
    Ayodele FO, Yao L, Haron H
    Sci Eng Ethics, 2019 04;25(2):357-382.
    PMID: 29441445 DOI: 10.1007/s11948-017-9941-z
    In the management academic research, academic advancement, job security, and the securing of research funds at one's university are judged mainly by one's output of publications in high impact journals. With bogus resumes filled with published journal articles, universities and other allied institutions are keen to recruit or sustain the appointment of such academics. This often places undue pressure on aspiring academics and on those already recruited to engage in research misconduct which often leads to research integrity. This structured review focuses on the ethics and integrity of management research through an analysis of retracted articles published from 2005 to 2016. The study employs a structured literature review methodology whereby retracted articles published between 2005 and 2016 in the field of management science were found using Crossref and Google Scholar. The searched articles were then streamlined by selecting articles based on their relevance and content in accordance with the inclusion criteria. Based on the analysed retracted articles, the study shows evidence of ethical misconduct among researchers of management science. Such misconduct includes data falsification, the duplication of submitted articles, plagiarism, data irregularity and incomplete citation practices. Interestingly, the analysed results indicate that the field of knowledge management includes the highest number of retracted articles, with plagiarism constituting the most significant ethical issue. Furthermore, the findings of this study show that ethical misconduct is not restricted to a particular geographic location; it occurs in numerous countries. In turn, avenues of further study on research misconduct in management research are proposed.

  13. Ethical Concerns About Human Genetic Enhancement in the Malay Science Fiction Novels
    Isa NM, Hj Safian Shuri MF
    Sci Eng Ethics, 2018 02;24(1):109-127.
    PMID: 28281149 DOI: 10.1007/s11948-017-9887-1
    Advancements in science and technology have not only brought hope to humankind to produce disease-free offspring, but also offer possibilities to genetically enhance the next generation's traits and capacities. Human genetic enhancement, however, raises complex ethical questions, such as to what extent should it be allowed? It has been a great challenge for humankind to develop robust ethical guidelines for human genetic enhancement that address both public concerns and needs. We believe that research about public concerns is necessary prior to developing such guidelines, yet the issues have not been thoroughly investigated in many countries, including Malaysia. Since the novel often functions as a medium for the public to express their concerns, this paper explores ethical concerns about human genetic enhancement expressed in four Malay science fiction novels namely Klon, Leksikon Ledang, Transgenesis Bisikan Rimba and Transgenik Sifar. Religion has a strong influence on the worldview of the Malays therefore some concerns such as playing God are obviously religious. Association of the negative image of scientists as well as the private research companies with the research on human genetic enhancement reflects the authors' concerns about the main motivations for conducting such research and the extent to which such research will benefit society.

  14. Application of loglinear models in estimating wet category in monthly rainfall
    Wahidah Sanusi, Kamarulzaman Ibrahim
    Sains Malaysiana, 2012;41:1345-1353.
    Climate changes have become serious issues that have been widely discussed by researchers. One of the issues concerns with the study in changes of rainfall patterns. Changes in rainfall patterns affect the dryness and wetness conditions of a region. In this study, the three-dimensional loglinear model was used to fit the observed frequencies and to model the expected frequencies of wet class transition on eight rainfall stations in Peninsular Malaysia. The expected frequency values could be employed to determine the odds value of wet classes of each station. Further, the odds values were used to estimate the wet class of the following month if the wet class of the previous month and current month were identified. The wet classification based on SPI index (Standardized Precipitation Index). For station that was analyzed, there was no difference found were between estimated and observed wet classes. It was concluded that the loglinear models can be used to estimate the wetness classes through the estimates of odds values.

  15. Prediction of tool life in end milling of Ti-6A1-4V alloy using artificial neural network and multiple regression models
    SALAH AL-ZUBAIDI, JAHARAH A. GHANI, CHE HASSAN CHE HARON
    Sains Malaysiana, 2013;42:1735-1741.
    Tool life of the cutting tools is considered as one of the factors which has effects on machining costs and the quality of machined parts. The topic of tool life prediction has been an interesting and important research topic attracting the attention of a wide number of researchers in this particular area. In terms of the suitable methods used in this research topic, it is stated that both statistical and artificial intelligence (AI) approaches can be employed to model tool life. For further justifying the capability of the ANN model in predicting tool life, the current study was based on conducting experimental work for collecting the experimental data. After carrying out the experiment, 17 data sets were collected and they were divided into two subsets; the first one for training and the second for testing. Since the data sets seemed to be lower than the number of data sets used in previous studies, we attempted to make verification of the ability of the ANN model in learning and adapting with low training and testing data. Diverse topologies accompanied with single and two hidden layers were created for modeling the tool life. For choosing the best and most effective network, the study adopted the mean square error function as criteria for the evaluation of the network selection. Thus, based on the data generated from the same experiment, a regression model (RM) was constructed employing the SPSS software. A comparison between the ANN model and RMs in terms of their accuracy was carried out and the findings revealed that the accuracy of the ANN was higher than that of the RM.

  16. Eigenstructure-based angle for detecting outliers in multivariate data
    Nazrina Aziz
    Sains Malaysiana, 2014;43:1973-1977.
    There are two main reasons that motivate people to detect outliers; the first is the researchers' intention; see the example of Mr Haldum's cases in Barnett and Lewis. The second is the effect of outliers on analyses. This article does not differentiate between the various justifications for outlier detection. The aim was to advise the analyst about observations that are isolated from the other observations in the data set. In this article, we introduce the eigenstructure based angle for outlier detection. This method is simple and effective in dealing with masking and swamping problems. The method proposed is illustrated and compared with Mahalanobis distance by using several data sets.

  17. An in vitro study to evaluate the genotoxicity of value added hydroxyapatite as a bone replacement material
    Akram Hassan, Swaminathan D
    Sains Malaysiana, 2011;40.
    Hydroxyapatite (HA) used for bone replacement is one of the most active areas of ceramic biomaterials research currently. It has been used clinically for the last 20 years due to its excellent biocompatibility, osseoconduction and osseointegration. Many modifications have been done to develop a stronger, tougher and biocompatible ceramic biomaterial because pure HA is brittle. Researchers in Universiti Sains Malaysia had developed this value added HA that is stronger and less brittle compared to pure HA. The objective of this in vitro study was to evaluate the genotoxic characteristic of the value added HA based material by using Bacterial Reverse Mutation Assay (Ames test). The Bacterial Reverse Mutation Assay of HA was performed on Salmonella typhimurium strains TA98, TA100, TA1535, TA1537 and Escherichia coli strain WP2 uvrA using the preincubation method in the presence and absence of an exogenous metabolic activation system. All the bacterial tester strains treated with and without S9 Mix showed no increase of revertant colonies with increase in concentration of test substance for both the dose finding test and the main test. The number of revertant colonies was less than twice that of the solvent control for all the five bacterial strains and this was reproducible for both the dose finding test and the main test. The numbers of revertant colonies in the negative and positive controls were within the background data of our laboratory. In conclusion the results of the tests showed that the value added HA was considered to have no reverse mutagenic potential under the present test conditions.

  18. Sensitivity analysis of the refinement to the mann-whitney test
    Abdul Rahman Othman, Lai CH
    Sains Malaysiana, 2014;43:1095-1100.
    The aim of researchers when comparing two independent groups is to collect large normally distributed samples unless they lack the resources to access them. In these situations, there are a myriad of non-parametric tests to select, of which the Mann Whitney U test is the most commonly used. In spite of its great advantages of usage, the U test is capable of producing inflated Type I error when applied in situation of heterogeneity or distinct variances. This current study will present a viable alternative called the refined Mann-Whitney test (RMW). A Monte Carlo evaluation test is conducted on RMW using artificial data of various combinations of extreme test conditions. This study reviews that the RMW test justified its development by enhancing the performance of the U test. The RMW test is able to control well its Type I error rates even though it has a lower power.

  19. Representing landslides as polygon (areal) or points? How different data types influence the accuracy of landslide susceptibility maps
    Simon N, de Roiste M, Crozier M, Abdul Ghani Rafek
    Sains Malaysiana, 2017;46:27-34.
    In the literatures, discussions on the accuracy of different models for landslide analysis have been discussed widely.
    However, to date, arguments on the type of input data (landslides in the form of point or polygon) and how they affect
    the accuracy of these models can hardly be found. This study assesses how different types of data (point or polygon)
    applied to the same model influence the accuracy of the model in determining areas susceptible to landsliding. A total
    of 137 landslides was digitised as polygon (areal) units and then transformed into points; forming two separate datasets
    both representing the same landslides within the study area. These datasets were later separated into training and
    validation datasets. The polygon unit dataset uses the area density technique reported as percentage, while the point
    data uses the landslide density technique, as means of assigning weighting to landslide factor maps to generate the
    landslide susceptibility map that is based on the analytical hierarchy process (AHP) model. Both data groups show striking
    differences in terms of mapping accuracy for both training and validation datasets. The final landslide susceptibility
    map using area density (polygon) as input only has 48% (training) and 35% (validation) accuracy. The accuracy for
    the susceptibility map using the landslide density as input data achieved 89% and 82% for both training and validation
    datasets, respectively. This result showed that the selection of the type of data for landslide analysis can be critical in
    producing an acceptable level of accuracy for the landslide susceptibility map. The authors hope that the finding of this
    research will assist landslide investigators to determine the appropriateness of the type of landslide data because it will
    influence the accuracy of the final landslide potential map.

  20. Fulltext Angular velocity and elevation angle: the proposed human model scalable tracking model using linear regression
    Yong CY, Sudirman R, Chew KM
    Sains Malaysiana, 2015;44(12):1661-1669.
    A scalable tracking human model was proposed for recognizing human jogging and walking activities. The model aims to detect and track a particular subject by using wearable sensor. Data collected are in accelerometer readings in three axes and gyroscope readings in three axes. The development of proposed human model is based on the moderating effects on human movements. Two moderators were proposed as the moderating factors of human motion and they are angular velocity and elevation angle. Linear regression is used to investigate the relationship among inputs, moderators and outputs of the model. The result of this study showed that the angular velocity and elevation angle moderators are affecting the relation of research output. Acceleration in x-axis (Ax) and angular velocity in y-axis (Gy) are the two main components in directing
    a motion. Classification between jogging and walking motions was done by measuring the magnitude of angular velocity and elevation angle. Jogging motion was classified and identified with larger angular velocity and elevation angle. The two proposed hypotheses were supported and proved by research output. The result is expected to be beneficial and able to assist researcher in investigating human motions.
