The hydrodynamic characteristics of new design for artificial reef with low flow
drag to provide suitable shelter for fishes and marine organisms in the Malaysian seas, were
studied in this paper. The concept used in the design is based on the streamlined bicycle helmet
design concept. The flow characteristics and the wave forces (FW) of the helmet and hollow
cube artificial reefs (ARs) of the same volume have been studied at a water depth and wave
celerties of Malaysia seas using Computational Fluid Dynamics (CFD) RANSE (ReynoldsAveraged
Navier-Stokes Eqs.) code Ansys Fluent. The Shear Stress Transport (SST) turbulence
model was used in the RANSE code. The streamlined body of the helmet artificial reef provides
flow zones with moderate flow speed at this area, which can help fishes and marine organisms
to find good shelter. The special shape of the different openings in the body of the helmet
artificial reef improves the condition of the flow velocity distribution inside the unit than that
of the hollow cube unit, which can increase the amount of the nutrient to the living fishes and
organisms inside the reef.
An increasing number of women participate in the work force due to socio-economic development result a big impact to work and family institution. Failure to meet demand for both work and family lead to work-family conflict that may give negative consequences on work and family. An example of major work-related outcome is burnout which can lead to turnover intention. Social support has been identified as an important resources that can reduce work-family conflict and burnout. This paper aims to identify the relationship between work-family conflict and turnover intention and also the mediation effect of burnout on work-family conflict and turnover intention relationship. It is proposed that there will be a positive relationship between work-family conflict and turnover intention and there is an indirect relationship between work-family conflict and turnover intention through the mediation effect of burnout. Social support from work and family is proposed to moderate the relationship between work-family conflict and burnout. Furthermore it is proposed that the strength of relationship between work-family conflict and turnover intention depends on the mediation effect of burnout and moderating effect of social support.
The dynamics of a liquid droplet in a low gravitational field is examined using a finite
difference/front tracking projection-based numerical technique. The unsteady, incompressible,
viscous, immiscible multi-fluid, two-dimensional Navier-Stokes equations for both the liquid and the
gas are solved using the single-fluid model. The droplet deformation and the gas wake generation and
oscillations phenomena is studied.
Knowledge is Power - one of the most important sayings that demonstrate an individual’s
growth and development to the highest level. Therefore, the goal of presenting this paper is to be able
to impart an in-depth understanding pertaining to various notions about knowledge sharing (KS)
presented in different institutions and also to raise some recommendations on how to improve
knowledge sharing in Malaysia. Moreover, the content of this paper is geared on exploring insights in
the Malaysian perspective of KS specifically in the public sector along with illustrating certain ways
of effectively enhancing KS in a particular organization. The information that is presented in this
paper were collected from various related literatures gathered from books, academic journals and
articles. Findings from several literatures revealed that most public sector employees are reluctant to
shared their knowledge as well as best practices, and this is regarded as the ultimate factors that
leads to poor quality and inefficient in the service delivery. Through the useful highlights in this
paper, it would provide beneficial information on contributing factor to enhance successful KS, not
only the Malaysian public sector but also to other countries with similar public sector settings and
culture.
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
– This study was performed to measure the gender equality involvement in Technical and
Vocational Education and Training (TVET) Program in one of the Malaysia Technical University
Network (MTUN). The focuses of this study are general perspective in gender equality, men and
women position in society, and sources of information about TVET. 200 respondents involving
students and lecturers from various field of TVET programs involved in this study. Questionnaire was
applied to gather the data information and descriptive analysis represent the findings. Result showed
that most respondents strongly agree with men helping in the household were women, they are also
aware about the national policies on gender equality in Malaysia, and for last section of survey,
respondents agree that they choose studying in TVET program because the better job opportunities.
In summary, there is no gender issue in Malaysia’s policy, position of work and opportunities in
further education especially in TVET programs.
In recent years, there has been an increasing interest in quadcopter technology
implementation in the real world; for instance in real estate photography, aerial surveying, periodic
forest monitoring, and search/rescue missions. Generally, each quadcopter implementation required
different sensors which are needed to attach and integrate into quadcopter system. However, the most
critical part in almost cases is preparing the quadcopter flight performance and capability to be suited
in any outdoor applications. Because of that reason, this paper has proposed an implementation of
Open-Source Project (OSPs) platform as autonomous Unmanned Aerial Vehicle (UAV) quadcopter
development that can be fitted for any outdoor applications or even in research experimental purposes.
We started out with an explanation about the general approach that has been used in the development
of a quadcopter testbed, and then followed with detail explanations in the OSP platform approach.
The OSP platform is the most popular approach. The main reason is because of their flexibility in both
hardware and software. The basic quadcopter configuration for autonomous flight also presented and
applied. This paper also provided several outdoor experiments results in uncontrolled environment
that have been executed using our developed testbed to evaluate their performance, such as attitude
and altitude stabilization, interference and vibration effect, and trajectory mapping generation.
Finally, throughout this project, we realized that the OPSs quadcopter platform has offered almost
complete frameworks in the development of quadcopter for any outdoor applications or even as a
research testbed system.
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
Rheumatoid arthritis (RA) is a chronic, disabling autoimmune disease which affects about 5 in 1000 people in Malaysia. Patients with RA are at increased risk of developing comorbid conditions. This research aims at determining these relationships between demographic, duration of illness and comorbidity in RA via a multiple binary logistic (MBL) regression analysis based on the 102 patients’ information (23 males; 79 females) obtained from the rheumatoid clinic of the Queen Elizabeth Hospital in Kota Kinabalu. The relationship of the RA patients with comorbid conditions was studied with focus on the demographic and duration of illness. The variables obtained for analysis were the comorbid conditions namely, hypertension and hyperlipidemia, age, duration of illness, gender, ethnicity, household income and education level. From six independent variables, two were quantitative would be analyzed, while four were categorical, and would be transformed into dummy variables. Four phases in a model-building approach were executed where two models were formed where Model I predicted the probability of occurrence of hypertension with age of patients and first order interaction between duration of illness before diagnosis and household income of less than RM1000 had positive effects on the model, while Model II predicted the occurrence of hyperlipidemia among the RA patients with age of patients and first order interaction variable between gender(female) and age were the contributing factors.
Study site: Rheumatoid clinic, Queen Elizabeth Hospital (QEH), Kota Kinabalu, Sabah, Malaysia
– Stroke is one of the deadly disease in Malaysia; one of top five major causes of death
and one of the top ten causes for hospitalization in Malaysia. Every year 40,000 people
diagnosed with this deadly disease. Stroke occurs when blood flow to the brain is blocked.
Blood supply essential nutrient and oxygen to the brain. Insufficient blood supply will cause
brain cell damages and lead to lose control of human body. Weakness or lost ability to upper
limb or arm is one of the main symptoms for the stroke patients. Normally only one part of the
body will affected. Upper limb post stroke rehabilitation objective is to help stroke survivor to
move their hand and arm as effective as their non-affected hand. Arm/ hand skate is one of the
popular equipment used to help the stoke survivor to regain their upper and/or forearm limb
strength and endurance of the patients. The main movement direction was horizontal from left
to right and reversed. In order to get the benefit of this exercise, stroke survivor has to repeat
this exercise for several time, this will lead to boredom and motivation lost. Another
disadvantage is there is no indicator for showing degree of the rehabilitation. Objective of this
study is to design a computer application using combination of C++, Open GL and optical
mouse which can be used to evaluate the stroke survivor hand and arm speed movement.
Information obtain from this application can used by the therapist and stroke survivor to
monitor their rehabilitation activity progress and effectiveness.
The present study investigated the correlation between occupational stress and job
satisfaction of police officers in Punjab, Pakistan. The sample consisted of 300 senior police
officers. The sample was further divided on the basis of gender differences. The sample was
selected from Punjab, Pakistan. Survey research method was used for data collection. Police
Stress Questionnaire (PSQ) was used for measuring the occupational stress and job satisfaction
was measured by Job Satisfaction Survey (JSS) scale. Results found that there is a negative
correlation between occupational stress and job satisfaction. It was also found that female
police officers have high occupational stress as compared to male police officers.
A study on 2D geo-electrical resistivity imaging at Melaka Tengah, Malacca was conducted to determine the potential groundwater zone. This investigation is needed to identify the quality of the groundwater, since the site is located in the coastal areas where groundwater influence tends to diminish due to intrusion of seawater. Two resistivity lines were proposed with length of 400m each by using Terrameter SAS 4000 and ES1064. Geo-electrical of electrical resistivity and induced polarization method with the Wenner-Schlumberger configuration were carried out. The Res2Dinv software would then render the 2D resistivity image through inversion method which provided detailed information of both the laterally and vertically geological structures based on their part. The electrical resistivity measured the resistance of the subsurface to the flow of electric current in units of ohmmeters and value of chargeability during the transient decay of the applied voltage in ms for induced polarization. Well data provided was very useful in direct determination of subsurface soil lithology.The result obtained showed an 84.7-meter subsurface depth for both areas which then reflected that the subsurface consisted of two different layers namely overburden (laterite, clay, and/or peat soil) with ranged 1 ohm.m – 10 ohm.m and 50 ohm.m – 500 ohm.m for schist formation. However, this area was considered to be brackish water area because of the low chargeability value of 0ms – 1ms especially in top soil layer and 5ms – 20ms for schist formation. Thus, this area was deemed not suitable for groundwater exploration due to the intrusion of salt water.

This article describes the approach towards a sensitivity study of wind flow and pollutant
dispersion in an idealized street canyon with tree plantings under thermal atmospheric conditions
using computational fluid dynamics (CFD). First, validation studies were performed to determine the
best turbulence model for the simulation of wind flow under thermal atmospheric conditions against
the previous experimental wind tunnel data. The results of the numerical simulation indicate that
large eddy simulation (LES) can accurately predict the wind flow structure at different thermal
intensities and different locations of heated wall. Finally, detailed descriptions of future research are
presented at the end of this article.
Nanofluid has become one of the interesting topics for engineers working for decades to
develop more efficient heat transfer in different applications. Nanorefrigerant, as a combination of
nanoparticles and refrigerant, is a new concept that has been recently investigated by number of
researchers. Electricity consumption usually varies from one sector to another. Generally, residential
sector is one of the biggest electricity consumers in Malaysia. Based on the literature, 26.3% of
electricity consumption in the residential sector in Malaysia is allocated to refrigerator–freezers.
This paper reviews the conceptualization and relationship among work-family conflict,
burnout, social support and turnover intention using Job Demand Resources (JD-R) model. From the
theoretical framework of JD-R model, there is a relationship between job demand and resources that
gives impact to organization outcome. In addition, empirical evidence also shows that a relationship
exists between the above variables. Organization should address proactively how job demand and
resources influence each other that lead to organization outcome. Comprehensive understanding
regarding the above matter gives opportunity for organizations to take reasonable action to ensure
employees well-being and give benefit to the organizations themselves.
