| Research Abstract |
In the first year, the environment for computer simulation was established and statistical analysis of sexually transmitted disease (STDs) was carried out. Tentative simulation of STD spread were also performed. According to the results of the statistical analysis, influential factors were not clearly identified, suggesting complex situation in the background. By the tentative simulations, importance of groups of different sexual activity was suggested.
In the second year, detailed (sex and age specific incidences) STD spread data was analyzed and specific patterns were extracted. These patters were well explained by sex and age specific mathematical model of STD assuming the age-specific contact rates observed in the questionnaire survey. Individual Based Model was also used in the simulation.
Two years of analysis revealed that the problem of sexual behavior and sexually transmitted diseases is very complex. We have to continue research for further understanding.
