Student of Library and Information Science Department Of Science and Research Unit of IAU Abstract: The environment is a field that interaction between world elements was occurred on it. The environment produces some information, and affects other elements that exist on that field. This interaction can be defined as processes. At the other hand, the human factor as an element, produce some information and take other. At this process the human factor may be passive or active. This processes and the way of information gathering were explained at this paper. Introduction: Human as a living organism is one of the complex environment elements. Such environment has other elements than human, that each of them is information potentially. Each of elements has his complexity and radiates information that can affect others. Also information has informative component, but sometimes overflowing of it can lead to a gap. Occurring a gap for each organisms, have same massages, that is, organisms or part of its encounter with a new situation that needs for new tools (information) or existing information dose not enough for solving of the problem. So, the gap should be removed and solving the problem is PDF created with pdfFactory Pro trial version www.pdffactory.com
