Radiographic Study of Developmental Alteration in Tooth Number Among Children in IIUM Dental Clinic

Background: The aim of this research was to determine the prevalence, distribution and association of developmental alteration in tooth number with gender, location, and presence of delayed eruption of tooth among children who attended to Student's polyclinic of IIUM Kuantan, Malaysia. Methods: A cross sectional study on total 727 Orthopanthomograms (OPGs) of 3-17 years old children from April 2009 to July 2012. OPGs with presence of alteration number were scrutinized to find out the prevalence, distribution and association. The data was analyzed comparing gender, location and presence of delayed eruption and tested using Chi-square test. Results: Out of 727 OPGs, 71 OPGs showed developmental alteration in tooth number. The prevalence was 98/1000 OPGs within 3 years. Among those 71 OPGs, the gender differences were: males (49.3%) and females (50.7%). Locations were found in maxilla (45.1%), mandible (40.8%) and both (14.0%). The finding of delayed eruption was (7.0%). There were significant differences between alteration in tooth number with location as (p<0.05) while there were no significant differences with gender and delayed eruption as (p>0.05). Conclusions: This study showed that hyperdontia was considerably lower than hypodontia. There was association between alteration in tooth number with location, but no association with gender and delayed eruption

Information security culture in healthcare informatics: a preliminary investigation

Information security culture becomes an enabler towards an effective security practice. Human factors are recognised as one of the factors in addressing the issue of information security in healthcare informatics. Inculcating information security culture among healthcare practitioners is identified to be one of the solutions for a better security practice. Thus, identifying the issues and factors that influence information security culture are important. A preliminary investigation involving six healthcare professionals and academics have been carried out for better understanding on the critical factors that may influence the information security culture. In-depth interview method is chosen in this study. Thematic coding was conducted to characterise the themes and asses the factor that found to be influential. Results from the indepth interviews with healthcare expertise showed that four main themes may influence the degree to which information security may be cultivated.

The research was intended to analyze the distribution network, marketing margin, profit and the marketing efficiency in every market. Descriptive method was used in this research, specifically descriptive method using study case approach and accidental sampling method. The result has shown that there are two distribution channels in every TPI 2 channels namely 1) Producer à fish wholesaler à Consumers and 2) Producer à fish wholesaler à Exporter. The marketing margins for the second line in all TPI from the same wholesaler is Rp. 50.000, - / kg. The marketing margin for the first line rock lobster between Rp.15,000,-/kg to Rp.25,000,-/kg. Sand lobster between Rp.20,000,-/kg to Rp.30,000,-/kg. The most efficient market value is the second line where the efficiency value is less than the first line\u27s efficiency value

Potential of natural fibres and their composites for South Asian countries: Moving towards sustainability

Increased environmental concerns and depletion of petroleum-based resources arising from the use of non-renewable resources have increased the demand of natural fibre reinforced composites (NFRCs). Composite materials reinforced with glass and carbon fibres have limited end-of-life (EoL) options, which is a major concern. To minimise this situation, lignocellulose plant fibres have been studied extensively in recent years, due to the increasing demand for sustainable lightweight and environmentally friendly materials. Natural plant fibres are considered as a viable substitute to E-glass fibres owing to their many attractive benefits, such as biodegradable, recyclability, high specific strength and stiffness suitable as reinforcements for many semi-structural and structural composite applications. This new class of lightweight sustainable composites can offer environmental, social and economic benefits as substitute materials for various applications. Through an up-to-date review, this work presents an overview of natural plant fibres as reinforcements of composites for various applications, especially in the context of the South Asian countries.Final Published versio

River flow and stage estimation with missing observation data using Multi Imputation Particle Filter (MIPF) method

An advanced knowledge of the river condition helps for better source management. This information can be gathered via estimation using DA methods. The DA methods blend the system model with the observation data to obtain the estimated river flow and stage. However, the observation data may contain some missing data due to the hardware power limitations, unreliable channel, sensor failure and etc. This problem limits the ability of the standard method such as EKF, EnKF and PF. The Multi Imputation Particle Filter (MIPF) able to deal with this problem since it allows for new input data to replace the missing data. The result shows that the performance of the river flow and stage estimation is depending on the number of particles and imputation used. The performance is evaluated by comparing the estimated velocity obtained using the estimated flow and stage, with the measured velocity. The result shows that higher number of particles and imputation ensure better estimation result
