Balancing needs, efficiency, and functionality in the provision of modeling software: a perspective of the NIH WinSAAM Project.

The development of new software or the refinement of existing software for new operating environments each calls for judicious balancing. On the one hand, we strive for simplicity, predictability, and operational protection as it is well recognized that software with these attributes will attract an audience of satisfied users. But, on the other hand, these attributes do not conjure a sense of power, efficiency, or flexibility, and these other properties are also appreciated by users, albeit a somewhat different group of users. The goal is to achieve a blend which isolates critical functionality, flexible control, and user support while meeting the needs of the broadest collection of serious users. In this chapter, we discuss the issues impacting the migration of SAAM to the Windows environment, the NIH WinSAAM Project, and we outline the steps taken to ensure its feasibility. In addition, we describe a new paradigm for software development and use which ensures the durability of the software for modeling.

[Prevalence of hepatitis B surface antigen in general population of coast, mountain and forest regions of Peru. A preliminary report].

A prospective study was performed in order to establish HBsAg prevalence on population living in urban areas of three geographical regions of Peru. There were included 100 apparently healthy people of each city, with a residence major to 5 years, no migrate neither transitory. Each subdivided group in 50 adults and 50 children. Of these last ones 15 between 1 to 7 years old and 20 cases between 7 to 14 years old. Samples were obtained by venipuncture, then they were centrifuged and the serum obtained was stored at -20 degrees C before being sent to Lima for processing. Determination of HBsAg was made by the Elisa's technic (Abbott Lab-III.-USA). In this preliminary report we informed about results in 7 cities (Lima, Iquitos, Chiclayo, Arequipa,Ica, Chachapoyas y Tarapoto) that include 680 persons of which 373 were adults and 307 children. The HBsAg, was positive in 26 cases (3.8%). In the adult group were 13 positives (3.4%), and in the children also 13 cases (4.2%). Result of all sample shows figures of prevalence (3.8%) major to that reported before at national level. The same phenomenon was observed in the cost while in the jungle our results were similar to those found before. In the andean area not studied previously there were obtained similar results to the rest of the country. It is also interesting to mention the high percentages of prevalence in children. These results indicate that hepatitis B is a serious problem of public health in our country that merit to take immediate prophylactic measures.
