Promoting complex global environment, tremendous growth and increase of network communication technology in the world, strategic planning and foresight activities in science and technology have become very important. Gradually, organizations and businesses are realizing the importance of foresight; many organizations attempt to execute such activities. However, this concept is not still well known in our country and among our organizations. Therefore, recognizing the factors influencing the success of this concept is a kind of issues that the organizations and activists are faced. Thus, this research seeks to identify and to rank the factors, particularly in the areas of economy, and it has developed five hypotheses. In this paper, factors affecting the success of foresight are given in four groups of rational, structure, scope, and results. Data collection for this study is a questionnaire and the binomial tests, Pearson correlation and Friedman test have been used to prove the hypothesis. According to the analysis of data obtained from the questionnaire conducted by SPSS software, all research hypotheses were confirmed. It also became clear that the rational component had the greatest impact on the future success of science and technology in the field of economic.

Ecotourism, as a multibillion dollars business, is an industry with high potentials for economic competition. One of the proper solutions for developing ecotourism is better identification of different regions where there is a tourism capacity and accurate planning for performing feasibility study of those regions in terms of attracting ecotourism as well as creating infrastructures in those regions. This paper evaluates capacities and power of tourism as well as nature tourism in Isfahan Township using Geographic Information System and Analytical Hierarchy Process. The present research is applied and research method is descriptive-analytical. Meanwhile, to analyze data, Arc GIS is used. Findings indicate that regarding the map of ecotourism capacity of Isfahan townships, resulted from combining various climatologically, geological, hydrological, topological maps and access maps, the township is not homogeneous in terms of nature tourism and coastal parts of the township (regions around Zayand-e-Rood) have better condition than other parts and should be considered for tourism development planning.
