SUBMISSION PROCEDURES FOR PEER REVIEW
Manuscripts Submission
Manuscripts should be submitted on-line at (http://submit.ogscience.org). Submission instructions are available at the website. All articles submitted to the journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication.
Peer Review Process
The editor selects peer referees by recommendation of the Editorial Board members or from the specialist database owned by the Editorial Board. Acceptance of the manuscript is decided, based on the quality and originality of the research and its clinical and scientific significance by the referees. A referee’s decision is made as “acceptance without revision,” “acceptance after minor revision,” “review after revision” and “rejection.” If there is marked discrepancy in the decisions between two referees or in opinions between the author and referee(s), the Editor may send the manuscript to another referee for additional comments and recommended decision. Three repeated decisions of “review after revision” are regarded as “rejection.” An initial decision will normally be made within 4 weeks of receipt of a manuscript, and the reviewers’ comments are sent to the corresponding authors by e-mail. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the referees’ comments item by item. Failure to resubmit the revised manuscript within 8 weeks of the editorial decision is regarded as a withdrawal.
Article Processing Charge
There are no page charges for submission or publication.

A short running head must also be provided, consisting of fewer than 40 characters including spaces. When other authors with a different address are included, first write the name of the organization where the primary research was conducted and the names of the other organizations along with the authors’ names, listed in numerical order. At the bottom of the title page, write the corresponding author’s address, phone, fax, and e-mail address.
    2) Abstract and Keywords
    The abstract should be no more than 250 words, and describe concisely, in a paragraph, Objective, Methods, Results, and Conclusion.

    3) Introduction
    Briefly describe the purpose of the investigation, including relevant background information.
    4) Materials and Methods
    Describe the research plan, the materials (or subjects), and the methods used, in that order. Explain in detail how the disease was confirmed and how subjectivity in observations was controlled. When experimental methodology is the main issue of the paper, describe the process in detail so as to recreate the experiment as closely as possible. The sources of the apparatus or reagents used should be given along with the source location (name of company, city, (state), and country).

    6) Discussion
    Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents in the introduction or results. Explain the meaning of the observed opinion along with its limits, and within the limits of the research results connect the conclusion to the purpose of the research.
    7) Acknowledgments
