14 Session 1 Summary Hoon Choi, KISTI – E-Science Environment for Avian Flu PRAGMA 16 – bioinformatics session on flu data integration, epidemiologically Data sharing, flu sequence data with China, and other AP countries Thanh Truong, U Utah – CSE-online, 2 nd generation, Avisto – astonis.com, free for high school, supported by advertisement – Molecular design, workflow management, connecting different graphically represented modules – Privately funded development

15 More … Jincheol Kim, KISTI – DrugScreener-G, Eclipse platform, currently only supports gLite middleware. A platform to support different applications. – Motuer workflow engine for EGEE; Kepler ? – Support interoperation of gLite, UNICORE. – Will integrate Opal to DrugScreener-G, utilize Gfarm services for data sharing. Hongwen Yang, CNIC – Virtual screening database Lucy Liu – Qinghai Lake Avian Epidemiological Observerations – Joint Research Center for wild life studies – E-Science demo application E-science is a process, not the ultimate goal.

16 From here to PRAGMA 16 Proposed activities towards PRAGMA 16 – Large scale SNP analysis – KISTI, J. Kim – Avian Flu workshop – Expanded targets among other infectious diseases – Collaboration with EGEE drug discovery activities
