Organization of Manuscripts

Manuscripts should be written in English or Korean, typescript and doublespaced, with approximately one inch margins. Avoid using footnotes and do not use italics for emphasis. Latin names should be given for all species used in the investigation. Where abbreviations are used, the word or words should be spelled out in full on initial appearance in the text, followed by the abbreviation in parentheses. In general, manuscripts should be organized in the following manner:

Title page

This page should contain:
· title of manuscript
· name(s) and affiliation(s) of the author(s)
· name, address, telephone number, fax number, and e-mail address of the corresponding author
· running title of no more than 50 characters
· five or fewer key words or phrases

Abstract

On a separate page, should not exceed 250 words and must be self-explanatory and clear to the non-specialist readers.

Introduction

Summarize the rationale and purpose of investigation and a brief survey of the existing literature on the subject. Do not use subheadings.

Materials and Methods

Provide enough detail to ensure the readers could repeat the described procedures, including statistical testing.

Results

Present the data without interpretation or subjective comments.

Discussion

Explain and interpret the data, especially as it relates to previous investigations. Present the highlights and limitations of this current investigation. State the conclusions and how they are supported by the data.

Acknowledgments

State all sources of funding for this investigation.

Conflict of interest

All financial and commercial conflicts of interest should be disclosed.

References

References should be numbered consecutively in the order in which they are first mentioned in the text. Authors should identify references in text, tables, and legends by Arabic numerals in bracket, e.g., MMPs are implicated in both differentiation and migration of cells and programmed cell death [1,2], and thus they have been regarded as key regulators in tissue development [1-3]. References cited only in tables or figure legends should be numbered in accordance with the sequence established by the first identification in the text of the particular table or figure. The titles of journals are abbreviated according to the style used in the list of Journals Indexed for MEDLINE, posted by the NLM on the Library’s web site (http://www.nlm.nih.gov). Authors are fully responsible for the accuracy of the references. The DOI (Digital Object Identifier), if available and if no print reference is available, should be provided. Manuscripts accepted but not published may be cited in the reference list by placing “in press” after the title of the journal. Examples of correct forms of references are listed below:

1.Jung UW, Um YJ, Choi SH. Histologic observation of soft tissue acquired from maxillary tuberosity area for root coverage. J Periodontol. 2008;79:934-940.
2.Brodre E, and Mark A. Bioenergetic Processes, 2nd ed., vol. 1, pp 62-77, Pergammon Press. Oxford, 1975.

Illustrations

All necessary illustrations should accompany the manuscript, but should not be inserted in the text. All photographs, graphs and diagrams should be numbered consecutively in Arabic numbers in the order to which they are referred in the text. Illustration files should be in TIFF, GIF, JPG, PDF, EPS, or Power- Point format and must be labeled on the title line as Figure 1, 2, etc. Figure legends should give sufficient information to make the illustration comprehensible without reference to the text.

Tables

Tables should be numbered consecutively with Arabic numbers. Type each table on a separate sheet, with titles making them self-explanatory. Tables should be provided in Word or HWP format not as graphic files pasted into text.

Proofs

Page proofs must be returned to the journal promptly. Proofs not received by the deadline will be published without the authors' corrections. Manuscripts that are accepted for publication are considered final copy and should not undergo any substantial changes in proof. Authors may be charged for excessive changes in proof, especially if these revisions cause publication delays.

Publication costs

1. Page charges: Basic page charge is $300, which includes the charge for 30 offprints for all published manuscripts.
2. Colour charges: Authors will be assessed a charge for each page with color figure(s). Color figures can generally be reproduced in acceptable quality in black and white if authors are unwilling or unable to pay for color charges. Authors are asked to contribute towards the cost of printing color figures.
