Abstract
A building designed with good maintainability considerations, not only functions as intended, but is also adaptable to current and future use. The purposes of incorporating good maintainability considerations into the design of a building are to achieve high building performance, ease day-to-day housekeeping tasks, make the building adaptable for future needs and maintain a stable usage cost throughout the building’s design life. This study identifies enablers that enhance building maintainability considerations in building design by applying structural equation modelling with the partial least square estimation (PLS-SEM) technique. The data collection methods in this research include an expert panel interview using prepared semi-structured interview questions and a questionnaire survey to identify the influencing factors to improve the maintenance-related needs of the building. This study identifies five significant enablers that could improve building design outcome by enhancing building maintainability considerations in Malaysia. The most significant enablers are developing efficient design tools that utilize information and analysis focusing on the user’s usage behavior.

Abstract
Renewable energy development as an alternative source of power supply has now been discovered and widely used. In fact, most users have begun to install one of the renewable energy known as solar photovoltaic (PV). Solar PV is installed in residential and industrial sectors as the government are considering every possible solution to increase the effectiveness of renewable energy. Solar PV has the feature that the energy stored from the solar energy into the battery will decrease at any time. Therefore, a monitoring system needs to be developed to measure power consumption based on the type of power supply currently being used, whether it be a primary power supply or a solar power supply. In this project, a system to monitor the percentage of energy supplied by solar PV as well as to inform the state of the solar panel via Interface. Information and data collected is obtained by monitoring the current and voltage through sensors installed and stored on a personal computer as well as using the Matlab application. Matlab is used to display data through graphical user interface (GUI) development. User friendly software in terms of organizing and controlling the system is created through the Interface. At the end of this project, this monitoring system will be used and applied mainly in residential and industrial sectors to enable measurement of solar energy performance.

Abstract
Vibration detection is an important feature in machinery health monitoring, in which used to detect faults and damages in heavy machines. This work demonstrated a fiber vibration sensor based on SingleMode-No Core-SingleMode (SNCS) fiber structure for low frequency vibration detection. When light coupled from Single-Mode-Fiber (SMF) to No-Core-Fiber (NCF), high-order Eigennodes will be excited and caused interference between different modes occurred along NCF. Different vibration frequencies change the interference pattern inside the NCF as NCF acts as multimode waveguide. Two sets of SNCS sensor with different length of 1.65cm and 2.85cm obtained an average Electric Field Norm (EFN) losses of 5.242% and 9.233% respectively. The SNCS sensor was proven to be capable in detecting vibration frequencies ranging 100Hz to 3000Hz with vibration intensity of 3V and 5V. The maximum relative error of the vibration frequency is 7.32143 × 〖10〗^(-9)%. The SNCS structure has the advantage of easy to fabricate, low cost and immune to electromagnetic interference, which can be used in critical environment.
DEEP LOCALISED CONTACT HAND BURNS IN CHILDREN: TWO CASES REPORT
Rahoma Ahmed Hussein, Shabbar Hussein
Abstract
The incidence of hand burns in children is high. In the overall cases of body burns, hand and wrist burns account for about 39%. They may constitute a part of a larger burn of the body, or an isolated injury of the hand and wrist. The choice between early and late eschar excision with skin covering is still a matter of debate. Two cases of deep burns of the hand were presented in this report. The report shows how to close the residual wounds of deep burns. One patient was a Malay child who sustained a deep contact burn in both hands. The other patient was a premature newly born Malay baby one-month-old, with Down’s syndrome. He suffered from a gangrenous patch (eschar) over the dorsum of the left hand after extravasation of drugs (chemical burn or necrotizing fasciitis). The two patients were treated by covering with local skin flaps after eschar excision and debridement. The result was good as patients did not develop any contracture as usual in similar cases.

Abstract
In this study, a small-scale wind turbine blade for the application in a low wind speed region was experimentally investigated. Savonius wind turbine design was selected and evaluated based on the feasibility of low wind speed at the National Defense University of Malaysia (UPNM). Six different Savonius Wind Turbine Blade (SWTB) designs were selected to investigate the effect of the number of blades, diameters, and types of materials. A wind tunnel experiment was carried out to investigate the performance of the wind turbine blades with different parameters. The experimental results were analyzed based on power coefficient (Cp), wind speed (V), tip speed ratio (TSR), torque coefficient (Ct) and electric power output (Pe). It was found that the number of blades and diameter were the most significant factor in designing SWTB. For this particular study, the least number of blades with the bigger diameter were more significant to increase the Cp values. The material factor was least significant to the design as this experiment verified that all the models produced the highest peak of Cp corresponding to the wind speeds. The effectiveness of this experiment was concurred by the highest power output produced.
