RINGKASAN: Implan khusus kepada seorang pesakit bagi pembinaan semula kecacatan maksilofasial telah memperoleh kepentingan disebabkan oleh prestasinya berbanding dengan implan generik yang lain. Keretakan pada bahagian orbital adalah kecederaan trauma terhadap tulang pada bahagian soket mata, yang mana biasanya disebabkan oleh daya yang kuat dikenakan pada sekelilingnya. Kecederaan orbital rim merujuk kepada kecederaan di tulang pada bahagian luar soket mata dan ia disebabkan oleh daya yang sangat kuat dikenakan pada bahagian tersebut seperti kemalangan kereta. Penulisan ini akan membentangkan kajian mengenai rekabentuk dan fabrikasi implan orbital menggunakan teknologi percetakan logam 3-Dimensi (3D), penggunaan perisian perubatan untuk menterjemahkan data pesakit daripada CT Scan kepada data pemodelan 3-Dimensi, membantu kaedah pakar bedah membuat perancangan pembedahan dan jurutera rekabentuk merancang rekabentuk orbital implan yang khusus untuk pesakit. Kemajuan dalam proses pembuatan seperti teknologi percetakan logam 3D untuk menghasilkan implan khusus pesakit telah menghapuskan kekangan yang dihadapi untuk menghasilkan implan yang memenuhi keperluan dari segi bentuk, saiz, struktur dalaman seseorang pesakit dan sifat-sifat mekanik yang membolehkan implan tersebut dihasilkan memenuhi keperluan fizikal dan mekanikal implantasi. Titanium asli digunakan untuk menghasilkan implan lantai orbit khusus pesakit. Proses pengesahan dilakukan dengan menggunakan model bercetak 3D di kawasan kecacatan orbital dengan pembinaan model implan khusus lantai orbit. Analisis sisihan dijalankan untuk mengkaji ketepatan implan khusus yang dibuat. Pelaksanaan teknologi percetakan logam 3D untuk pembentukan implan dan penilaian pembinaan semula intraoperatif membantu kepada peningkatan penampilan estetik seseorang pesakit.

Salted egg is a popular delicacy for Asian populace originated from ancient Chinese recipe. The current method of production is through preservation using red soil and brine coating which can take a minimum of 2 weeks before reaching the threshold of saltiness acceptation. Recent research shows that the introduction of Pulse Pressure Osmotic Dehydration (PPOD) method will be able to reduce the absorption time. This innovation is faster and more effective than the making of salted egg by using traditional salting. The focus is on the use of air pressure chamber prototype generated using 3-dimensional printing technology which was Selective Laser Sintering (SLS). The usage of 3D Printed air pressure chamber with different combination of NaCl-H2O and pulse strategy to the egg specimen, identifies time taken in reaching the threshold value (based on commercially available salted eggs) of salt absorption. The preliminary result shows that this method is capable of shortening the osmotic dehydration time for egg salting.

Wireless Power Transfer (WPT) using Magnetic Resonance Coupling (MRC) caught the significant attention from the researchers in academia and industries worldwide due to its higher power transfer efficiency especially at medium distances. In this regard, various circuit topologies have been proposed for further improving the efficiency. This review emphasizes the efficiency analysis of WPT system using circuit equations. This literature survey covers the two, three and four coils WPT system. In addition, review of multiple coils WPT structure is also presented. Frequency decrease analysis, impedance matching and frequency splitting phenomenon are also discussed. The two operating principles, maximum power transfer and maximum energy efficiency are described. This is followed by safety standard for WPT technology. Finally, a comparison of Inductive Wireless Power Transfer (IWPT) and Resonant Wireless Power Transfer (RWPT) is provided. This review will be helpful for the readers to understand the circuit structures and operating principles of the WPT technology.
