This on-going process has created new landscapes instrumental to man＇s balance of the use of the land by taking into account the probability of further natural disasters. This paper discusses the responses to disaster challenges taking past experiences on ＂after disaster decisions＂ in London 1666, in Lisbon 1755 as a framework to analyse the more recent Great East Japan Earthquake disaster. The concept of sustainability which adds a new perspective to the subject of more resistant solutions and strategies as the opportunity for a new design is presented by the destruction. Sustainable environmental, social and cultural issues improvements are important goals introduced in the 20th century and enrich long-term human adaptations to natural processes. They are also considered in this analysis as an evolving final product of the human adaptation that results in more durable cultural landscapes.展开更多

The QLD （Queensland） State Government has established the Queensland Reconstruction Authority within one month. Recovery works in QLD seem to be very smooth, and transfer phase to the normal civil works is going to start. Eastern Japan also attacked by the great earthquake and following Tsunami on March 11, 2011. Japanese Government, however, established the Reconstruction Agency almost one year after the event. The reconstruction of the disaster area is still on the halfway. This paper aims to find out the differences between two countries from the viewpoints of organization, planning process and financial conditions.展开更多

However, the significance of sex pheromones in shaping mate choice （sexual selection） and in competition over breeding resources （social se- lection） has been largely ignored. The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute, while the role of sex pheromones in competition over breeding resources （other than mates） has not yet been considered. As a result of natural selection, variation in sex pheromones among females is expected to be low, and males are not expected to choose their mates among phero- mone-releasing conspecific females. Sexual selection, on the other hand, should drive the increase in pheromone variance among females, and males are expected to choose females based on this variation. Moreover, social selection resulting from more general social interactions, for example competition among females for breeding sites and food, should also promote variance among female sex pheromones. Here, we review the cttrrent evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait. We suggest that the three selection types are not mutually exclusive but rather act together to promote different fimess components in diverse ecological situations展开更多
