Objective Give the description of unlicensed prostitute population who work in entertainment place, analyze the character of their social network, trying to find the bottleneck of accompanier education at present and effective measure of breakthrough, give the building of"accompanier intervention"elucidatory evidence.Methods The strategy of the whole study is qualitative analysis. At the forepart of the study, backdate study are used for review the literature of preventing AIDS in unlicensed prostitutes population in China. We are interested in preventing effect, structure and flow of that. Then the unstructured and non-participant observation is used for collecting the information of the population. Social network questionnaire technology is used for collecting data coming from locale and object. This step is called structural observation. Finally, we handle the data with UCINET6.0.Results Social network analysis in unlicensed prostitute population: 1) UNIVARIATE STATISTICS shows the most influential person and the person who will be the negative point in later step of prevention; there is no solution of finding these points in prevention flow at present. 2) REACHABILITY is common phenomenon that places are rich in reachability, but there are also some of them make very bad practice in this area, they give difficulty index of evaluation in accompanier education ,also there should be differences of detailed strategy between each places, but there are noting related at present . 3) GEODESIC DISTANCE index are between 1 and 1.5,it gives hint that information in accompanier education will be present itself as attenuation, but people are always concerning about sending out information.4) TRANSITIVITY shows the proportion of clustering structure and structure-holes present the degree and locality of obstacle ,there are no related technique at present. 5)CLUSTERING COEFFICIENT gives Overall graph clustering coefficient and Weighted Overall graph clustering coefficient scale the efficiency of information transmission, it locates the highlight, but not at present.6) RECIPORITY STATISTICS is the same as in the dyad-based model, the stabilization explain the effect of intervention and obstacle at the same time,7) KRACKHARDT GTD MEASURES include the index of Connectedness, Hierarchy, Efficiency and LUB it gives the potential of improving stability , strategy of accompanier education at present lose this visual angle.8)P1 is divinable what the structure will be like at some levels of likelihood, as far as it predicts the right way that information of intervention flow by the relationship as times go by, there is no timing angle of view about forecast of preventing effect.Conclusion Combining the result of social network analysis investigates, the study make some false-proving to some techs of the accompanier education strategy at present. The social network analysis is feasible technology. Enriching the doctrinal background of preventing AIDS in unlicensed prostitutes population with SNA theory, the problem as following, lack of bestrow, shortcoming of subjectivity, inefficient preventing and difficulty in persistent improving of some related index can be resolved. |
