    Abstract: Research on NAO robot-mediated Autism Spectrum Disorder (ASD) therapy intervention via telerehabilitation network has been gaining popularity in recent years. It eliminates the distance barrier between a therapist and a child with autism by allowing remote physical interactions between them thus enabling the therapy to be conducted even in a long-distance. In general, the system requires a robot, a child with autism, and a helper which normally is a close kin to be present at one place and a specialized therapist at another. Connected via remote communication technology such as the Internet of Robotics Things (IoRT), a remote therapist is able to monitor the therapy session through robot vision or its sensors and if necessary, provide physical feedbacks through robotic features such as voice or body movements. One of the system’s important aspects is the therapist’s interface controlling the robot. The interface must be user-friendly to non-programmer user yet having enough technical features to control a sophisticated NAO robot. Choregraphe, an official NAO robot platform and interface to program and control the NAO robot, has many advanced programming functions. Thus, it is considered quite intimidating to the non-programmer user, in this case, a specialized therapist. As an alternative to this interface, this paper reviews the suitability of commercially available software, Zorabots, as the therapist’s interface to monitor and control NAO Robot in telerehabilitation environments.

    Abstract: The influence of thermal annealing on the surface morphologies and structural characteristics of zinc oxide (ZnO) nanopowders synthesized via the solution immersion method for triboelectric nanogenerator applications is reported in this paper. The ZnO nanopowders were thermally treated at different temperatures of annealing in the ranges between 300°C to 700°C for 1 hour, and their surface morphologies and structural properties were studied using field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analysis. The ZnO nanopowders have a polycrystalline, hexagonal wurtzite structure and are composed of ZnO nanoparticles and hexagonal nanorods. ZnO based tribolectric nanogenerators were fabricated with these nanopowders and their performance was assessed in terms of the output voltage. It is found that the ZnO based triboelectric nanogenerator fabricated with ZnO nanopowders annealed at 500°C has superior performance compared with the other nanogenerators, with an average output voltage of 1.95 V. This corresponds to a fourfold increase in output voltage relative to that of the ZnO based triboelectric nanogenerator fabricated with as-deposited ZnO nanopowders. In conclusion, thermal annealing significantly influences particle size and crystallinity of ZnO nanopowders, which in turn, influences the output voltage of ZnO based triboelectric nanogenerators.

    Abstract: Nanostructured iodine-post doped amorphous carbon (a-C:I) thin films were prepared from camphor oil using a thermal chemical vapor deposition (TCVD) technique at different doping temperatures. The structural properties of the films were studied by field-emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), Raman, and Fourier transform infrared (FTIR) studies. FESEM and EDS studies showed successful iodine doping. FTIR and Raman studies showed that the a-C:I thin films consisted of a mixture of sp 2 - and sp 3 -bonded carbon atoms. The optical and electrical properties of a-C:I thin films were determined by UV–vis–NIR spectroscopy and current–voltage ( I – V ) measurement respectively. The optical band gap of a-C thin films decreased upon iodine doping. The highest electrical conductivity was found at 400 °C doping. Heterojunctions are confirmed by rectifying the I – V characteristics of an a-C:I/n-Si junction.

    Abstract: A novel self-prepared Aerosol-Assisted Chemical Vapor Deposition (AACVD) system was developed to deposit the amorphous carbon (a-C) thin films for the carbon-based solar cell applications. The nitrogen doping was applied towards the a-C thin films at deposition temperature of 600°C and 650°C. The samples gave the photoresponse characteristic for the electrical measurement by using the solar simulator system in under illumination condition. FESEM images signify the nanostructured sized a-C:N ( 〈 100nm) and EDX spectrum clarify the presence of N content in the N doped a-C. Solar cell efficiency was also obtained with the value of 0.001648% for 650°C and 0.000124% for 600°C when the a-C:N were deposited on p-Si substrate. The presence of the rectifying curves at the a-C:N/p-Si junction indicates the hetero-junction behavior between the p-n structure and thus proves the successful doping of N doped a-C using the AACVD technique.

    Abstract: Pure amorphous Carbon (a-C) thin films had been deposited by Aerosol-Assisted CVD (AACVD) onto glass substrate in Argon atmosphere. The camphor oil was chosen as the carbon precursor to prepare the a-C thin films with the deposition time of 15 minutes, 30 minutes, 45 minutes, 60 minutes and 75 minutes. The electrical, optical and structural properties of the deposited a-C were discussed by using the current-voltage solar simulator system, UV-Vis-Nir spectrophotometer and Raman spectroscope respectively. For the electrical characterization, the samples showed the photoresponse performance when being illuminated under AM 1.5 illuminations: 100 mW/cm 2 , 25°C. Transmittance value for the a-C thin films was also considered high ~80% and the structural analysis by using Raman spectroscope exhibit two main peaks known as the D-peak and G-peak which is typical for the a-C.

    Abstract: Background and Purpose: Gamification is a teaching and learning approach that is gaining popularity among teachers as a way to make classroom learning more enjoyable and engaging with the use of rewards to celebrate accomplishments. With the rise of online learning in Malaysian educational institutions, gamification is viewed as an interactive method of teaching and learning. Due to the fact that limited studies have been conducted to investigate the challenges in implementing gamification approaches among vocational instructors, it is the aim of this paper; therefore, to examine the challenges.   Methodology: This study employed a quantitative research method. The respondents include 55 vocational lecturers from several vocational colleges in Malaysia. A set of questionnaires was used to examine the challenges faced by the lecturers in the implementation of gamification at their institutions. Four constructs were used to differentiate the differences of the challenges, which include support, access, competency, and applicability. Data collected from this study were analyzed using descriptive statistics (mean score and standard deviation) and inferential statistics (independent sample t-test) to identify the differences between gender.   Findings: The findings of this study indicated that the majority of vocational lecturers have moderate challenges when implementing gamification approaches in their teaching and learning based on the findings related to the constructs. In addition, it was found that there were no significant gender differences in terms of the difficulties associated with implementing gamification approaches. This study also showed that most vocational lecturers have the potential to apply gamification in their teaching based on their high competencies with adequate support and enough access given to them.   Contributions: The findings of the study can contribute to vocational lecturers to promote gamification approach during the learning process to increase students’ motivation.     Keywords: Gamification, gender, challenges, approach, vocational.   Cite as: Marlissa, O., Dayana Farzeeha, A., & Fathiyah, M.

    Abstract: Amorphous carbon-based material has attracted a considerable attention for optoelectronic and photovoltaic applications. This remarkable element has expected to have similar properties as silicon and highly stable. This work is focused on the deposition conditions of amorphous carbon thin film for optoelectronic and photovoltaic application. However, amorphous carbon has a complicated structure and high density of defects. Due to the limited factors of the deposited amorphous carbon film, a doping process is required. The amorphous carbon and iodine doped amorphous carbon thin films were deposited on glass and silicon substrates by thermal chemical vapor deposition (CVD) technique using camphor oil as the precursor. The effect of doping temperature in the a-C and a-C:I thin films on electrical and optical properties were characterized. The conductivity of a-C:I thin films increased with the doping temperature at 450°C and it shows large photoconductivity. The photovoltaic behaviour was improved by doping the a-C with the iodine. Effective doping will encourage the future prospect of low cost, clean and high efficiency of carbon-based device.
