Transforming Model to Meta Model for Knowledge Repository of Malay Intangible Culture Heritage of Malaysia

Intangible Culture Heritage is very important as national treasure for a country since it is a part of identity of the country. Rapid technology changed and globalization is one of the reasons why new generation less interested to involve in culture heritage sector. Without any drastic action to safeguard Intangible Culture Heritage for the country it will cause endanger to disappearance. In this study researcher introduce a model of factors that contributing in archiving Intangible Culture Heritage. By transform from the model to meta model it will be a guidelines, standard and base for developing a repository of Intangible Culture Heritage. The finding for this research is a vital and very fruitful for intangible study and archiving and also as a main contribution for this study.DOI:http://dx.doi.org/10.11591/ijece.v2i2.20

Kepuasan Kerja Guru Siswazah Sekolah Menengah Di Bagan Serai

The aim of this study is to examine whether the six chosen factors from the Herzberg Two Theory Factor would give a great satisfaction in work or otherwise to the graduate teachers. It also aimed to look at the correlation between the intrinsic and extrinsic factors with regard to work satisfaction and whether these factors have any significant on work satisfaction. This study involved 175 graduate teachers from nine schools in Bagan Serai, Perak. A set of questionaires with 47 items was used as the instrument in this study. The questionaires were modified from the questionaires of 'Faculty Opinion Survey' by Seegmiller (1977) and 'Minnesota Satisfaction Questionaires' by Weiss, Dawis England and Lofquist (1967). Seven null hypotheses were developed for this study. The data acquired were then analyzed using descriptive and the inferential statistical methods which involve Pearson correlation and multiple regression. It was found that factors such as responsibility, the principles and management of an organization including the opportunity to develop one self are the three important factors which gave great satisfaction in work. However, factors such as salary is the least important in work satisfaction. Results of the multiple regression analysis show that factors such as the chances to be promoted, the principles and management of an organization and the opportunity to develop one self, as a whole, have significant effect to the satisfaction in work among graduate teachers. Some suggestions have been provided to enhance the satisfaction in work among graduate teachers

Effect of Oral Corrective Feedback on Language Skills

Corrective feedback is an important element in the language learning process. The issue of corrective feedback in language classrooms has been investigated by numerous scholars who believe that the strategy can effectively be used to improve the language skills of students. Though many forms of feedback approaches are used in learning, oral corrective feedback is the commonly used strategy in teaching languages. This is mainly because it captures the diverse elements of language lessons such as pronunciations and spelling. Oral corrective feedback presents a broad field which assists both teachers and students in error identification and eradication. It mainly focuses on highlighting the common errors and mistakes and addressing them enabling the students to avoid them in the future. This paper mainly explores the impact of oral corrective feedback on the language skills of learners. It generally analyses articles that address the issue of oral corrective feedback and derives information regarding the impact of the strategy in language learning outcomes

Magnetohydrodynamic boundary layer flow in a nanofluid with various stream conditions

Magnetohydrodynamic (MI-ID) nanofluids boundary layer flow, is one of the fields of study that has caught the attention of many researchers due to the extensive applications of this flow in extrusion of plastics, the cooling of reactors, textile industry, polymer technology, metallurgy, geothermal engineering and liquid metals and plasma flows. This thesis investigates the convective heat transfer in magnetohydrodynamic boundary layer flow of nanofluids over various geometric surfaces (flat, vertical or wedge) subjected to different boundary conditions. Two models were used in this study: Tiwari-Das model that takes into account the effect of the volume fraction of nanoparticles and Buongiomo model that combines the effects of Brownian motion and termoforesis. Five problems are considered in this study taking into account the effect of various parameters such as the effect of the magnetic field, the volume fraction of nanoparticles, Brownian motion, thermophoresis, chemical reactions, thermal stratification and the presence of micro organisms and particles of carbon nanotubes (CNTs). In all cases, the mathematical models which resemble the physical flow of the problems are developed. The governing partial differential equations are reduced to a system of ordinary differential equations by using one of the following transformations: similarity transformation, local similarity transformation or local non-similarity transformation. These ordinary differential equations are then solved numerically using the shooting method for different boundary conditions. Numerical solutions for velocity, temperature and concentration profiles as well as the skin friction coefficient or local Nusselt number are obtained and presented either graphically or in tabular forms and the main features of the problems are discussed and analyzed. It is observed that the skin friction coefficient and the local Nusselt number which represents the heat transfer rate at the surface are significantly influenced by all the parameters studied. Using the Tiwari-Das model, the results indicate that increasing the volume fraction of nanoparticles increases the skin friction coefficient and the local Nusselt number. The results also showed that carbon nanotubes (CNTs) are the best particles to be dispersed in common based fluid due to its unique thermal properties and structure. Although producing the governing equations for the Tiwari-Das model is simpler than that of Buongiorno model, Tiwari-Das model ignores the velocity slip effect of nanoparticles which is important in explaining the existence of nanoparticles in the base fluid. Instead in Buongiorno model, these velocity slips are rep.resented by the Brownian motion and thermophoresis parameters. However, results showed that both of these effects only affect the temperature and concentration profiles but not the velocity flow profiles
