    Objective: This study examined the influence of visual art therapy techniques in reducing anxiety level
    among 4 to 6 years old paediatric dental patients.
    Methods: Eleven subjects were selected among 4 to 6 years old paediatric dental patients. The initial
    reaction towards dental procedure/treatment was evaluated using Frankl Behavior Rating Scale. The
    anxiety level was assessed by using Malay-Modified Child Dental Anxiety Scale (MCDASf
    ) to measure
    a child situational anxiety of pre- and post-treatment. Visual art making activities included free drawing,
    clay moulding and collage technique. The participant reaction to dental treatment was assessed by using
    Frankl Behavioural Rating Scale for two subsequent independent visits in two weeks interval. Median
    and Ordinal Test ranked the variables score of behavioural reaction towards dental treatment and anxiety
    level.
    Results: Play-doh (PD) subjects could accept dental procedures more if compared to free drawing (FD)
    and storytelling by collage (ST) subjects, which has lower post treatment-median scores in Visit 1 and
    Visit 2, FD and ST subjects need more time to show positive attitude towards dental treatment.
    Conclusion: These findings suggest dental anxiety level of children aged 4 to 6 years old reduced after
    the art therapy and play-doh(clay-moulding technique) is the art making activity of choice among 4 to 6
    years old paediatric dental patients.

    Objective: This study aimed to assess the awareness of periodontal disease and level of knowledge of the relationship between smoking and periodontal disease amongst subjects who were smokers verses non-smokers.
    Methods: A questionnaire looking at knowledge of respondents regarding gum disease and knowledge and awareness about oral impacts of smoking on periodontal disease was developed and pretested in Dental Faculty University of Malaya. Basic Periodontal Examination (BPE) index was used to assess periodontal status.
    Results: The questionnaire was answered by 130 subjects. Prevalence of smoking was 14.6%. A total of 58.6% non-smokers and 57.9% smokers knew about periodontal disease. However, only 26.1% non-smokers and 10.5% smokers knew that the cause for periodontal disease was plaque. More non-smokers than smokers knew that smoking affected periodontal health (80.2% and 68.4% respectively) (p>0.05) and tooth mobility was an effect of smoking on periodontal health (27.0% and 0%) (p<0.05). Regarding source of information on effect of smoking on periodontal health, 63.2% smokers and 63.1% non-smokers reported obtaining information through the mass media. However, only 31.6% smokers and 28.8% non-smokers were informed by their dentist.
    Conclusion: The awareness of periodontal disease and knowledge of the relationship between smoking and periodontal disease was low in this selected population of smokers and non-smokers.

    Aim: Self-assessment based on benchmarked professional standards is an excellent tool to assist in improving the dental curriculum. Areas of strength and weaknesses can be identified. It can also act as a baseline standard when significant changes are introduced to the dental curriculum. The aims of this prospective cross-sectional study was to investigate self-assessed confidence of final year dental undergraduates in paediatric dentistry enrolled at University of Malaya in 2013. Methods: 65 undergraduates completed anonymised questionnaires which were formulated based on expected professional competencies in three domains namely clinical skills, patient management, and professional development and clinical governance. Visual analogue score (VAS) represented by a 10cm line with score ‘0’ no confidence at all and ‘10’ complete confidence was used to measure the level of confidence. Results: The overall analysis of self-assessed confidence was very positive with median VAS ≥ 5cm in; clinical skills, 7.66±1.31cm (range=2.41–9.97cm: n=62; 95.4%), patient management 7.73±1.27cm (range=5.09–9.95cm: n=64; 100.0%), and professional development and clinical governance, 8.13±1.21cm (range=5.22–10.00cm: n=64; 100.0%). High confidence was reported for routine dental care (fillings and preventive care) while lower confidence reported for basic life support (median VAS=5.65cm) and pulp therapy for immature permanent teeth (median VAS=5.95cm). Conclusions: The final year dental undergraduate students of the University of Malaya appear to have good overall self-assessed confidence in core areas in paediatric dentistry.

    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.

    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.

    – 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.

    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.

    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

    Previous studies on instant noodles have been aimed mostly at secondary students, and have
    been concerned with the demographics, and the development of product attributes. Very few studies
    have examined the role of convenience (CO), product attributes (PA), advertising (AD) and subjective
    norms (SN) in predicting the intention of students towards the consumption of instant noodles. The
    present rising costs of living and education may affect the intention and behaviour of university students
    towards the consumption of affordable food. Therefore, the purpose of this paper was to explore the
    relationship between these variables and the variables of the Theory of Reasoned Action (TRA) in
    association with the intention of university students to consume instant noodles. A research model
    approach was used to reflect the effects of CO, PA, AD, and SN on the TRA constructs. In total, 390
    cases were gathered from three universities. Structural equation modelling was employed to assess the
    proposed research model in terms of the path significance, the general requirements for a model fit,
    and the testing of the hypotheses. It was found that AD has a direct positive effect on the behavioural
    intention of university students towards the consumption of instant noodles. Nevertheless, CO, PA, and
    SN appear to exert no significant influence on the behavioural intention of university students. The
    limitation of the study was that the findings were obtained from a small dataset covering only three
    universities. Therefore, future researches should cover a broader range of research samples. This paper
    provides additional understanding for marketing managers and researchers into the effects of CO, PA,
    AD and SN on the intention of Malaysian university students towards the consumption of instant
    noodles, which can be used for formulating marketing strategies for instant noodles and for considering
    future research directions in other countries.

    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.
