How to reviews of previous studies in scientific research and the mechanism for its analysis

     How to reviews of previous studies in scientific research and the mechanism suffers junior researchers analyzed the mechanism of reviews, compilation and analysis of previous studies in the research, which was being prepared by, this is a group of things that the researcher followed when he writes of previous studies and analysis, to deliver properly:-

1.The researcher to compile the previous studies that are related to his or her problem research, and then removing spent fuel rods in a timely manner depending on the previous models.

2. a researcher to determine the extent of the relationship between these studies with the research problem in relation to directly or indirectly.

3. a researcher analyzed the previous studies in terms of its subject, the work of the independent or its members have a separate or personnel to GASTROENTEROLOGY or an independent requirement, with regard to the degree of relationship is only relative to the discretion of the researcher.

4. a researcher design of the agenda containing columns on the elements of his or her problem research, and contains the cells of its ranks on previous studies, and then determine what you wrote these studies on the elements of the research problem, and then write in a separate paper what i wrote all these studies in this component and other.

5. a researcher to add the score and other items within the conurbation columns such as: Concepts of procedural concepts and jargon, the methodology of the study the study tools, sources and references, article scientific and obstacles and results.

     But there are a range of considerations that the researcher observed when the previous studies, namely:-

*only a researcher review of previous studies a writer after writer or study after study indicating shortcomings in this study, but is presented according to the themes of all the studies, the researcher focuses on: &'what she or those of previous studies of eminent persons together on the element of the proposed research.

*How I wrote these studies on the various elements.

*How many who wrote in every element.

*do respondents agreed or different or conflicting views and to any degree?.

 *what is the general orientation or feature in this consensus.

      **these studies collectively addressed all elements of the research problem in a manner that leaves no room for other studies on the subject? Or dealt with some of the shortcomings of some of its elements, or only dealt with adequately? 

Or have addressed all the elements a weak and sporadic curricula patchy led to false results, according to the researcher, therefore, indicates the lack of previous studies addressed the problem of research from the same corner, the curriculum itself, and that there are aspects of these studies are still in need of research.
