The objective of this study was to describe the social and cultural factors related to schistosomiasis transmission in three Egyptian villages where prevalence rates of diseases are high. Data reported are based on focus group interviews collected among children and adults. Topics discussed were knowledge about disease, transmission behaviors (risky behaviors), risk perceptions, prevention behaviors (response to risk), symptoms, treatment behaviors, treatment satisfaction, knowledge of prevention, source of information, and more general concerns and grievances. Both adults and children were concerned about schistosomiasis, and were knowledgeable about disease symptoms, transmission, control, and risky behaviors such as swimming in canals or polluting their banks. The adults were concerned with lack of col...

It is a distributed version of a standard Prolog interpreter designed for exploiting OR-parallelism and pipe-lined AND parallelism. Some distinctive features of DISPO is that it speeds up the execution of Prolog programs and generates all possible solutions for a query, i.e. it works as an all-solutions Prolog virtual machine. The effectiveness of its distribution technique and load balancing equations resulted in a 70% average speedup in the execution time of a number of Prolog benchmark programs. These results are presented graphically with a detailed analysis of system performance.
