Pekerja industri adalah lebih mudah untuk terdedahkan kepada ketidakselesaan dan kesakitan semasa kerja. Faktor-faktor risiko pekerjaan merupakan faktor terbesar kepada masalah-masalah kesihatan dan ia boleh didapati di mana-mana industri. Di negara perindustrian, anggota badan bahagian atas lebih terdedah kepada gangguan musculoskeletal. WMSDs merupakan gejala di mana pekerja akan mengalami kesakitan dan ketidakselesaan di leher, kawasan bahu, belakang, siku, tangan, badan dan lutut, dan juga pada sendi yang sakit, keletihan dan cedera. Namun terdapat kekurangan kajian dalam bidang ini yang memberi tumpuan dan pendedahan tentang kepentingan implikasi reka bentuk kepada manusia. Tambahan pula, terdapat juga kekurangan penyelidikan dalam bidang ini untuk merangkumi masalah yang berkaitan ergonomik kepada manusia dengan menggunakan simulasi komputer. Kertas kerja ini membentangkan trend terkini mengenai penggunaan simulasi komputer visual dalam mendedahkan ketidakselesaan selain gangguan yang dialami oleh pengguna kerana reka bentuk yang tidak ergonomik di tempat kerja atau penggunaan produk mereka. Tiga kajian kes telah dijalankan ke atas penggunaan jenis perisian yang berbeza dalam bidang ergonomik iaitu CATIA-RULA, OWAS dan Pemetaan Tekanan FSA4.0. Dapatan kajian menunjukkan trend WMSDs di kalangan pengguna adalah membimbangkan dan secara dramatik penting untuk keselesaan pengguna.

Industrial Ergonomics

This paper describes various ways in which digital computer simulation can be used by ergonomists in the design of industrial systems. Also shown are recent advances in this methodology which make the technique even more effective and features of the technique which require particular concern. A variety of past simulation studies with human factors considerations are cited for detailed use by practitioners.

Induced spinodal decomposition under electron irradiation in a Ni-Au alloy has been investigated with respect to its basic mechanism and confirmed to be caused by the relaxation of coherent strain associated with modulated structure. Modulation of white-dots on structure images of modulated structure due to high-resolution electron microscopy is reduced with irradiation. In this paper the atom arrangement of the modulated structure is confirmed with computer simulation on the structure images, and the relaxation of the coherent strain is concluded to be due to the reduction of phase-modulation.Structure images of three-dimensional modulated structure along <100> were taken with the JEM-4000EX high-resolution electron microscope at the HVEM Laboratory, Kyushu University. The transmitted beam and four 200 reflections with their satellites from the modulated structure in an fee Ni-30.0at%Au alloy under illumination of 400keV electrons were used for the structure images under a condition of the spherical aberration constant of the objective lens, Cs = 1mm, the divergence of the beam, α = 3 × 10-4 rad, underfocus, Δf ≃ -50nm and specimen thickness, t ≃ 15nm. The CIHRTEM code was used for the simulation of the structure image.

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.
