| 8241 | 2019 Article | Contamination level of Aflatoxins in Traditional Herbal Medicinal products (Jamu and Makjun) marketed in Malaysia. Suriani Mohamed Safety assessment for traditional herbal medicinal products such as “jamu” and “makjun” in Malaysia include the laboratory tests for heavy metals, microbiology and scheduled poisons. Test for aflatoxins is not included. Aflatoxin B1 (AFB1) is genotoxic and carcinogenic. Its possible contamination in these products should be ruled out. In this study, 12 samples of “jamu” and “makjun”, analyzed using IAC clean-up and HPLC were found to have a mean levels of positive samples (incidence) as 0.97 (17%), 0.24 (17%), 0.92 (8%), 0.30 (8%) and 1.82 (17%) µg/kg, and the range was 0.94 - 0.99, 0.06 - 0.42, 0.92, 0.30 and 1.00 - 2.63 µg/kg, for AFB1, AFB2, AFG1,AFG2 and total AF, respectively. Low contamination level might be attributed to the antifungal effects of some medicinal herbs.

| 8242 | 2019 Article | Tertiary Eeducation saving patterns among Malaysian parents Fatimah Salwa Abd. Hadi While tertiary education provides many benefits to the individual, the community and the nation, we cannot deny that the cost is high and continues to rise each year. The younger generation have to take up loans to finance their study costs and then they have to pay back the loans after completing their studies. As such, the funds from the parents can be seen as an alternative which could help in realizing the tertiary education goal. The question is, do the parents realize and know the importance of tertiary education savings? Have they saved for their children’s education? How much do they save per month? Are the savings enough for their children’s university education? What is the savings medium utilized to make savings? Therefore, this paper focuses on two main objectives. The first objective is to identify the patterns of children's tertiary education savings among parents in Malaysia and the second objective is to determine the medium of saving used by parents to save their..... 1556 hits |
| 8243 | 2019 Article | Synthesis, characterization and in vitro bioactivity of chitosan- hydroxyapatite composite doped with magnesium Ismail Zainol This work reports the synthesis, characterization and in vitro response of a novel chitosan-hydroxyapatite composite doped with magnesium. Hydroxyapatite (HA), magnesium doped HA, chitosan-hydroxyapatite composite and the novel magnesium doped chitosan-hydroxyapatite composite were synthesised using coprecipitation method. The effects of magnesium and chitosan incorporation on the structural properties of the samples were studied by X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Bioactivity studies of the samples in simulated body fluid (SBF) was carried out. The incorporation of magnesium and chitosan into the lattice of the HA reduced the crystallinity and crystallite size of the HA. The chemical composition of the novel magnesium doped chitosan-HA composite was found to have resemblance to that of bone mineral. The novel material showed good bioactivity in SBF.

| 8244 | 2019 Article | Critical factors influencing the payment of shariah non-compliant money Fatimah-Salwa Abd. Hadi This study was conducted to test the validity and reliability of Strategical Instrument on Memorizing al-Quran (ISMEQ) using Rasch Measurement Model that was aided with the Winstep 3.72 software. This instrument contains 54 items that consist of four construct and 10 sub-construct. The first construct was the objective strategy with two sub-construct which were the ability to memorize with a given timeline and the ability to memorize by per page a day. Meanwhile, the second construct was planning strategy with a sub-construct that consist of prior, during and after memorizing planning. The third construct was memorizing enforcement activity with two sub-construct which were preservation of hafazan and practice. Then, the fourth construct was effective strategy with four sub-construct whichconsist of internal and external motivational, interest and behavior. This study was conducted on 31 SMA Imtiyaz Besut students and 55 students from SMKA Kota Kinabalu. The result from this study sh..... 1281 hits |

| 8246 | 2019 Article | The roles of teacher and students via blended problem-based learning: improving students mastery of three representation levels of Chemistry Mokhzani Ibrahim The current practice in teaching Chemistry subject is found to be teacher-centered where teachersengage actively in transmitting knowledge while students act as passive recipientsof knowledge. This might affect students’ mastery in learning three representation levels of Chemistry (macroscopic, microscopic and symbolic). As a result, students tend to formanon-scientific understanding and develop an alternative concept. The shift to Blended Problem-based Learning (BPBL) is therefore potential to help overcome this problem. Thus, this study is aimed atinvestigatingthe roles of teacher and students in overcoming the formation of alternative conceptsfor three representation levels of Chemistry inBPBL. This study applies acase study research design. Two teachers and 20 students from two different Fully Residential Schools are selected using purposive sampling technique. ..... 931 hits |
| 8247 | 2019 Article | The influence of contextual approach to students problem solving ability of class IX of SMP Negeri 1 Bayang Yerizon Yerizon The purpose of this study was to investigate the effect of student’s problem solving abilities with contextual approaches. Student’sproblem solving ability is still low because the teacher does not associate mathematics material with student's real world situations. In addition, students are also less active especially to find mathematical concepts. To overcome this problem, a Contextual Approach was applied in mathematics learning. This research is a quasi-experimental research using a quantitative approach. The research population was students of grade IX students at SMPN 1 Bayang. The used technique for sampling is random sampling. The research sample was of class IX.2 as an experimental class and class IX.3 as a control class. The used instrument was a problem solving ability test and questionnaire. Data obtained through tests were analyzed using two-way variance analysis...... 666 hits |

Firstly, intuitionistic fuzzy control point is defined based on intuitionistic fuzzy and geometrical modeling concepts. Each of the control point relation that consists of three function is find and shown. Later, the control point is blended with B-spline basis function and intuitionistic fuzzy B-spline curve is visualized. Some of the control point and space curve properties in the Euclidean space is also discussed throughout this paper

| 8249 | 2019 Article | Extrema points application in Determining Iris region of interest Zuraini Othman Extrema points are usually applied to solve everyday problems, for example, to determine the potential of a created tool and for optimisation. In this study, extrema points were used to help determine the region of interest (ROI) for the iris in iris recognition systems. Iris recognitionis an automated method ofbiometricidentification that uses mathematical pattern-recognition techniques on the images of one or both irisesof an individual'seyes, where the complex patterns are unique, stable, and can be seen from a distance. In orderto obtain accurate results, the iris must be localised correctly. Hence, to address this issue, this paper proposed a method of iris localisation in the case of ideal and non-ideal iris images. In this study, the algorithm was based on finding the classification for the region of interest (ROI) with the help of a Support Vector Machine (SVM) by applying a histogram of grey level values as a descriptor in each..... 704 hits |
