The purpose of this study is to explore the issues and challenges in integrating
technological pedagogical content knowledge (TPACK) for computer programming
courses. This study employed the triangulation method of the case studies and
Grounded Theory (GT). Twenty-five computer programming educators were
interviewed via online such as e-mail, media social’s chatting and messaging
application like WhatsApp and Telegram. The main issue discovered in this study is the
misconception in using technology for teaching and learning computer programming.
Besides that, there were two major challenges found in this study. The challenges are
the instructors were not able to explore the rapid development of technology and this
may cause the lack of technological pedagogical knowledge among them. They also
showed the lack of knowledge about pedagogy and assessment for teaching and
learning computer programming that relevant to the programming content. The
research that has been done showed that TPACK model is very suitable to guide
exploration about how educators make use of technology appropriate to the pedagogy
and content. However, the exploration that has been done has limitation on how
educators integrate student’s assessment on affective and instructional design
implementation with TPACK. Therefore, this paper suggesting for the future study, in
order that more exploration should be doing about how assessment on student’s
affective and instructional design would be integrate with technology, pedagogy and
content knowledge via TPACK model.

The fragmented and unstable nature of the construction industry associated with
unpleasant working environment caused the diminishing preference of potential
manpower to participate in the construction industry. An increasing number of
construction firms are experiencing severe outflow of the workforce, not limited to loss
of manpower, but contemporaneously, expertise and valuable experiences too. The
construction industry is conservative and particularly resistant to synchronise with
hectic and rapid changes to content and accommodate current demands.
Accumulation of a few causes such as the refusal of locals to involve, unsatisfied
working conditions, labour-intensive trades, etc had caused workforce scarcity as the
supplies unable to overcome and cope in-parallel with the demands. The objective of
this study was to identify labour composition (profiles) at construction sites. The
method used to fulfil the objective was face to face questionnaire survey to the
targeted respondents. The questionnaire consisted two (2) sections; details of the
construction project and details of construction labours such as background, education
and training level, working experiences, general welfare and working hours and wages.
The collected data were analysed using percentage distribution methods and
presented in the tables and charts for easy understanding. From the result gathered,
the respondents’ education level is low and most of them are from the Philippines and
Indonesia. Most of them acquire the construction skills through site experience and no
formal training. The majority of them stayed off-site comfortably with their family and
being paid according to their skills.
Large costs associated with employee turnover due to stress among the offshore
worker can be related to the individual and organisation factors. This article presents
the relationship between individual and organisational factors toward occupational
stress of off-shore worker. A quantitative method has been carried out to investigate
the relation of interpersonal relationship, job characteristics, and organizational role
toward stress among the operators in an offshore platform. Set of data has been
gathered from respective respondents, then analysed using Statistical Package for
Social Science (SPSS) version 21.0. For the credential, the data were initially tested for
its reliability, then were analysed using frequency analysis, Pearson's correlation
analysis, coefficient regression analysis and SWOT analysis. The findings indicate that
job characteristics, interpersonal relationship, organizational role have a significant
influence toward the occupational stress. However, this study shows that
organizational role is identified as major contribution to the occupational stress of the
offshore workers. A few recommendations to manage stress among the workers have
been identified. It is expected that this could reduce the number worker of turnover
due to stress.
An effective sharps injury prevention program includes several components that must work in concert to prevent healthcare personnel from suffering needlesticks and other sharp related injuries. Sharp injury management program in Kementerian Kesihatan Malaysia (KKM) is currently at surveillance state outlined in the Manual of Sharp Injury Manual Surveillance 2007. Latest data showed that as much as 1405 cases reported in Kementerian Kesihatan Malaysia facilities in 2011. In Hospital Melaka, high sharp injury prevalence was recorded with 25 per 1000 healthcare worker being affected each year. However, according to World Health Organization, surveillance data tend to underestimate the true rate of sharp injuries between 18% and 70%. Although reasons for sharp injury underreporting are well documented in many studies, less in known on what motivates healthcare personnel to report their injury. In order to encourage healthcare workers engagement to prevention program, these motivators need to be determined. Various factors affecting reporting behavior can be divided into organizational factors and health belief. The objective of the study is 1) to determine the level of awareness and compliance on sharp injury reporting among healthcare workers in Melaka, 2) To identify the relationship between awareness of reporting, organizational factors and health belief with sharp injury-reporting behavior among healthcare workers, 3) To determine the impact of awareness on reporting, organizational factors and health belief with sharp injury reporting behavior among healthcare workers, 4) To suggest improvements in sharp injury prevention program. Healthcare workers who reported sharp injury between 2011 and 2015 were invited to answers questionnaires pertaining these factors. Descriptive statistics, mean scores and multiple logistic regression were used for the analysis. Results and recommendation are discussed.

Solar updraft tower power plant (SUTPP) is an alternative technology for electricity
generating from solar energy. It’s suitable for use in remote area, where there is high potential of
solar radiation, because the constructions are cheap and the technologies involved are conventional.
This paper presents the design of a circular and square collector SUTPP to be used in rural areas of
developing countries. The design involves heating air using solar energy and the tower effect to raise
the hot air up the tower. From this study, a small scale solar updraft tower with 2m length in each
side of solar collector, air inlet height of 0.1 m above the ground, an updraft tower of 1.5-meter-high
with 2.0 m length of each side collector was studied to determine its performance. Anemometer and
multimeter were used to measure the velocity and temperature along the collector and inside the
tower. Solar radiation, ambient air temperature as well as air velocity inside the tower were also
recorded. These data were taken every one hours in four days to investigate the performance of the
SUTPP
Heat pipes are widely used in various industries such as automotive, electronics, and many more. Heat pipes are used as cooling devices for electronic parts in machines that emit a large amount of heat, which can damage the devices. The heat pipes used in this investigation are loop heat pipes. These pipes can transport heat over a long distance and operate against gravity. The working fluid used in this investigation is nanofluid. Nanofluid is one of the types of working fluid that is considered to have better thermal performance than conventional fluids. Nanofluid is made of nanoparticles with base-fluid. This investigation studies the thermal performance of loop heat pipes using different types of nanofluids. Nanofluid fluids used in this study are diamond nanofluid, aluminium oxide nanofluid and silica oxide nanofluid. The effect of mass concentration of nanoparticles in the base-fluid is also studied. The results showed that as the mass concentration of nanofluids increased, the thermal resistance for diamond nanofluid and aluminium oxide nanofluid decreased, but the opposite occurred for silica oxide nanofluid but still better resultsthan pure water. This shows that diamond and aluminium oxide nanofluids shows better thermal conductivity as it has lower total thermal resistance and thermal enhancement rate compared to other nanofluids. Diamond nanofluid also had higher heat capacity than aluminium oxide nanofluid as it had a lower vapour line temperature reading.
Low-cost high rise housing project is developed to provide a chance for low-income
citizen to own a house at a lower market price. Each low-cost high-rise residential

Most tropical rainforest tree species depends on forest gaps for their successful
regeneration. Evaluation on the gap or canopy openness provides an indicator on the
forest development stages. This paper reported on the canopy openness (CO) of three
study plots at (1-, 9-, 18-year old) rehabilitated forest sites and one study plot at natural
regenerating secondary forest (± 22-year old) in UPM-Mitsubishi Corporation Forest
Rehabilitation Project, Universiti Putra Malaysia Bintulu Sarawak Campus (UPMKB).
Plot of 20 x 20 m was established where dendrometric parameters were collected
while Delta-T Device HemiView system was used to take the hemispherical photograph
and field observation information were used to assess the CO. Qualitative analysis of
the photographs suggested there were three stages of forest growth namely gap,
building and mature stand development phases. These also helped the interpretation
of the quantitative analysis in relation to forest dynamics. Hemispherical photographs
were used for quantitative analysis of the CO. CO showed statistical significant
differences among study plots which recorded a range of 3-78%. Rapid analysis of CO
on the hemispherical photographs with information from the dendrometric
measurement had assisted in assessing the forest stand development. The canopy
openness was dependent on the age of the rehabilitated forest. Overall, the study plots
were in the different stages of stand development.
Mobile health (m-health) has become one of most concerned and developing areas in
healthcare industry. There are large numbers of m-health application available in the market. Yet,
neither theorist nor practitioners has discover or develop a framework in evaluating the impact of nonclinical
m-health application. In healthcare industry, it is very important for an m-health application
to be tested first before release to market, as this could lead to negative impact towards user especially
patients. Money could be wasted and the m-health apps might not derived correct output. To avoid a
failure in using non-clinical m-health application, the impact of using it need to be evaluated.
Nonetheless, to come out with a proposed framework for m-health apps evaluation, the theories and
results of the existing frameworks should be referred to. Thus, this research aimed to discuss on the
previous frameworks that are possible to be used as reference in proposing the intended framework.
The new developed framework is expected to be significant and valuable for all m-health developers
and doctors in the design and use of non-clinical m-health application.
This study aims to investigate the direct and indirect effect of entrepreneurial leadership
on organization demand for innovation. Over the past years academic debates have mostly focused on
individual’s demand for innovation while emphasizing on the organization's success in producing new
products and services to individual customers. However the organizational customers and
organization's demand to use innovation in day to day work has been generally neglected. Since
previous studies identified leadership as an important determinant of innovation in the organization,
this research proposes a conceptual framework to explore the effect of entrepreneurial leadership on
organization’s demand for innovation. The success of entrepreneurial leadership depends not only on
the behaviors of the leader, but also on the characteristics of their followers in demonstrating
entrepreneurial behaviors. Therefore this study aims to examine the moderating role of follower’s
reliance on social networks to recognize new opportunities on the relationship between
entrepreneurial leadership and organization’s demand for innovation. A sample of Malaysia Top 100
Companies participates in this research and the hypotheses are evaluated using Partial Least Squares
(PLS) analysis. This research makes an important contribution by providing empirical evidences that
may support entrepreneurial leaders and their firms to identify and generate more opportunities and
enact them in ways that increase the organization's receptivity towards innovation

The present study reports on the preparation processes and characterization of fibers from pineapple cores. The effects of different washing techniques (tap-water and hot-water washing) and particle sizes (0.2, 0.5 and 1 mm) on two important characteristics of dietary fiber, i.e. water holding capacity (WHC) and oil holding capacity (OHC), were investigated. It was found that the washing pre-treatment significantly improved WHC. Meanwhile larger particle sizes of fiber gave better WHC and OHC for all types of fibers. Tap-water washing was the most appropriate pretreatment method compared to hot-water washing and unwashed method. However, there was no difference in morphologies of the fibers before and after being prewashed at different particle sizes. The fiber morphology was preserved best after the drying process using microwave freeze dryer (MFD) and microwave vacuum dryer (MVD). This study demonstrates the potential of pre-treatment and drying methods in functional fiber preparation for food enrichment.
Jerky, a ready-to-eat snack, known for its high protein and low-fat content. Current
methods used in jerky processing take 6-10 hours in a conventional oven, dehydrator
or smokehouse. In this study, whole buffalo meat was sliced to 5mm and 6mm and
cured in three different salt concentrations of 1.0%, 1.5% and 2.0% for 24 hours at
4°C. The effects of microwave finish drying (5, 10 and 15 seconds) were examined
after samples were dried in a convection oven for three hours. Cured buffalo slices
showed significant (p
Besides traditional chemical stabilizers, polymer emulsion that is considered as a nontraditional
chemical stabilizer had been introduced recently. Among polymer emulsions, Canlite and
Probase have been widely used for soil stabilization. The aim of this paper is to investigate the
effectiveness of Laterite soil stabilization treated by Canlite-liquid and Probase-liquid soil stabilizers.
A testing program, scheduled to achieve the overall objectives of this study was conducted to
determine the basic properties of Laterite soil, establish the relationship between the compaction
characteristics (maximum dry density and optimum moisture content) with the amount of polymer
emulsion and last but not least to compare the strength of the Canlite-treated and Probase-treated
Laterite soil. The effects of both polymer soil stabilizers – Canlite and Probase – were examined. The
optimum moisture content of the mixtures was used as a reference to determine the water content for
the preparation of all the specimens and later used in the unconfined compressive strength (UCS) test.
The laboratory test results showed that the additional amount of Canlite and Probase have improved
the physical properties, liquid limit and unconfined compressive strength (UCS) of the Laterite soil.
The compressive strength of the treated Laterite was found varied and depends on the type of
stabilizers, quantity of additives and curing time. From the UCS tests, it was found that Probase
improves the strength of the Laterite more than Canlite.
