The research conducted a thorough review of evidence and effectiveness of digital serious games (SGs) for communication of action-oriented key messages (related to tsunami evacuation) to children. Significant scientific research investigates tsunami risk which is not always effectively communicated to children who are expected to make appropriate decisions during a tsunami event. SGs can motivate children and enhance risk communication. Computing technologies offer a delivery platform to access digital SGs which require little educator training and motivate learners. The research reviewed evidence of effective SGs that address tsunami risk and are deployable by educators. Based on this review, it is evident that very few suitable classroom deployable, digital SGs that address tsunami evacuation decision-making are available. Results showed only 2 suitable, available games. Similarly, while general evidence of the effectiveness of digital SGs was found, the evaluation of and evidence for the specific effectiveness of the available games was extremely limited. The education establishment and disaster community could exploit SG technology more effectively to communicate natural hazard risk to children in a global context where such risk is increasing. The research informs future game development projects which need to embrace comprehensive stakeholder involvement and inputs. Recommendations for serious game development projects are proposed.

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.

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.
