The aim of this study is to review the capacity and capability of hearing among impaired students in a transition termed as a Career Transition Programme in adapting to the working environment post-school graduation. This research is a qualitative research by making use of a designed survey. The Career Transition Programme is a programme that helps students with special needs in getting a job after school. Students with hearing difficulties experience hardships in communicating and socialising with the outside community. Data were collected by observing the participants as well as traditional face-to-face interviews with employers, workers, parents and teachers at school. The participant in the study is a student necessitating special needs undergoing hearing difficulties in one elementary school with special education for the disabled. The training module was designed as a guide for the participant to carry out work at a chosen nursery. The study found that the participant acquired all the taught skills and managed to work according to the assigned hours. The results of the interview show a positive outlook on the Career Transition Programme that was carried out. However, the researcher suggests some improvements in the Career Transition Programme in ensuring the longevity of its implementation from time to time in the future.

Although fame synthesis promises economic beneft and rapid synthesis of carbon nanotube (CNT), the lack of control and understanding of the efects of fame parameters (e.g., temperature and precursor composition) impose some challenges in modelling and identifying CNT growth region for obtaining better throughput. The present study presents an investigation on the types of carbon precursor that afect CNT growth region on nickel catalyst particles in an ethylene inverse difusion fame. An established CNT growth rate model that describes physical growth of CNT is utilised to predict CNT length and growth region using empirical inputs of fame temperature and species composition from the literature. Two variations of the model are employed to determine the dominant precursor for CNT growth which are the constant adsorption activation energy (CAAE) model and the varying adsorption activation energy (VAAE) model. The carbon precursors investigated include ethylene, acetylene, and carbon monoxide as base precursors and all possible combinations of the base precursors. In the CAAE model, the activation energy for adsorption of carbon precursor species on catalyst surface Ea,1 is held constant whereas in the VAAE model, Ea,1 is varied based on the investigated precursor. The sensitivity of the growth rate model is demonstrated by comparing the shifting of predicted growth regions between the CAAE model and the VAAE model where the CAAE model serves as a control case. Midpoint-based and threshold-based techniques are employed within each model to quantify the predicted CNT growth region. Growth region prediction based on the midpoint-VAAE approach demonstrates the importance of acetylene and carbon monoxide to some extent towards CNT growth. Ultimately, the threshold-VAAE model shows that the dominant precursor for CNT growth is the mixture of acetylene and carbon monoxide. A simplifed reaction mechanism is proposed to describe the surface chemistry for precursor reactions with nickel catalyst where decomposition of the ethylene fuel source into acetylene and carbon monoxide is accounted for by chemisorption.

The purpose of this research is to determine the effectiveness of reducing the negative behaviours of remedial pupil during the teaching and learning (T&L) process in the classroom. The research was conducted on a selected remedial pupil of a chosen primary school in Kulai district of Johor. The researcher used “Smiley Magnets” as economic tokens to reduce the pupil’s behavioural impromptu exits, sulking and uncooperative behaviour during group works in the research subject. Normally, the use of economic tokens are usually physical tokens or points system given to minimise the negative behaviours and indirectly encourage the positive behaviours. The research subject whom behaviours were sulking, uncooperative during group works and behavioural impromptu exits could be reduced by giving “Smiley Magnets” as tokens and would be rewarded with desired gift after completing 10 “Smiley Magnets”. This research is a qualitative research that used an A-B-A technique which is A represents the Baseline phase and B represents Intervention phase. Structural observations were carried out in 6 weeks which include the pre, while and post intervention. Observations were carried out, video recorded and ticked in the checklist form. The gathered data were then transferred into the graph line and tables to measure the effectiveness of the interventions that were carried out. The findings of the research showed that the practical use of “Smiley Magnets” to change the negative behaviours of the concerned pupil worked and produced positive results. This research aims to be the guide for teachers who tackle the same issue of changing pupils’ negative behaviours.

This quantitative study was conducted to examine the relationship between psychological capital, organizational support and subjective well-being of Special Education Teachers. A total of 196 Special Education Teachers were randomly selected from 40 secondary schools in the Central Region of Peninsular Malaysia. Psy Cap Inventory, Special Education Career Resilience Scale and Life Satisfaction Scale questionnaire method were used to collect the relevant data. The Cronbach alpha reliability coefficient of the Psy Cap Inventory is 0.85-0.90, Special Education Career Resilience Scale is between 0.75 - 0.94 and Life Satisfaction Scale is between 0.80-0.95. The findings showed that statistically significant positive relationship between psychological capitals, organizational support and subjective well-being. The multiple regression analysis indicates that psychological capital and organizational support contributed 33% (R square = 0.332) of the variance being accounted for in subjective well-being and this was found to be statically significant with organizational support and psychological capital are major predictor contributed significantly. Lower contribution of psychological capital and organizational support towords subjective well-being shows that there are also other factors that affect the subjective wellbeing of Special Education Teachers.

Zero‑dimensional model for the prediction of carbon nanotube (CNT) growth region in heterogeneous methane‑flame environment

The conventional multi-scale modelling approach that predicts carbon nanotube (CNT) growth region in heterogeneous flame environment is computationally exhaustive. Thus, the present study is the first attempt to develop a zero-dimensional model based on existing multi-scale model where mixture fraction z and the stoichiometric mixture fraction zst are employed to correlate burner operating conditions and CNT growth region for diffusion flames. Baseline flame models for inverse and normal diffusion flames are first established with satisfactory validation of the flame temperature and growth region prediction at various operating conditions. Prior to developing the correlation, investigation on the effects of zst on CNT growth region is carried out for 17 flame conditions with zst of 0.05 to 0.31. The developed correlation indicates linear ( zlb=1.54zst +0.11) and quadratic ( zhb=zst(7-13zst )) models for the zlb and zhb corresponding to the low and high boundaries of mixture fraction, respectively, where both parameters dictate the range of CNT growth rate (GR) in the mixture fraction space. Based on the developed correlations, the CNT growth in mixture fraction space is optimum in the flame with medium-range zst conditions between 0.15 and 0.25. The stronger relationship between growth-region mixture-fraction (GRMF) and zst at the near field region close to the flame sheet compared to that of the far field region away from the flame sheet is due to the higher temperature gradient at the former region compared to that of the latter region. The developed models also reveal three distinct regions that are early expansion, optimum, and reduction of GRMF at varying zst.
