In academic year 2008, Thammasat University campaigns for greening university with an emphasis on behavioral change as part of continuous effort to reduce harmful activities to the environment. The Faculty of Fine and Applied Arts organizes a Green Campus Green Design Project with a co-operation of the Institute of East Asian Studies. This project, follows from the University`s philosophy, aims to create behavior change through collaborative art creation process. We focus on creating awareness on how an individual can change to help save our planet starting from small daily activities to every aspect of our daily life. A series of art lectures, workshops and exhibitions is jointly designed by a Korean communication arts artist and our staff together with a Thai specialist in natural dye to be an environmental friendly process. All participants, Thammasat University students and lectures as well as students from neighboring schools and international communities, learns to create inspirational arts and to start "green- acts". Notable change can be observed both in students and faculty members. The shared art experiences and the joint efforts of organizations in this project demonstrate some lessons learnt in stimulating individual to take responsibility for saving our planet.

<P>A fundamental mystery for dengue and other infectious pathogens is how observed patterns of cases relate to actual chains of individual transmission events. These pathways are intimately tied to the mechanisms by which strains interact and compete across spatial scales. Phylogeographic methods have been used to characterize pathogen dispersal at global and regional scales but have yielded few insights into the local spatiotemporal structure of endemic transmission. Using geolocated genotype (800 cases) and serotype (17,291 cases) data, we show that in Bangkok, Thailand, 60% of dengue cases living <200 meters apart come from the same transmission chain, as opposed to 3% of cases separated by 1 to 5 kilometers. At distances <200 meters from a case (encompassing an average of 1300 people in Bangkok), the effective number of chains is 1.7. This number rises by a factor of 7 for each 10-fold increase in the population of the 'enclosed' region. This trend is observed regardless of whether population density or area increases, though increases in density over 7000 people per square kilometer do not lead to additional chains. Within Thailand these chains quickly mix, and by the next dengue season viral lineages are no longer highly spatially structured within the country. In contrast, viral flow to neighboring countries is limited. These findings are consistent with local, density-dependent transmission and implicate densely populated communities as key sources of viral diversity, with home location the focal point of transmission. These findings have important implications for targeted vector control and active surveillance.</P>

We show differences in the propensity of serotypes to cause disease in individuals with dengue antibodies (infants and post-primary cases) and in individuals without dengue antibodies (primary cases). The mean age of infant cases differed among serotypes, consistent with previously observed differential waning of maternal antibody titers by serotype.
