PUBLICATION TYPES, QUALIFICATIONS FOR AUTHORS

Five types of manuscripts are published in this journal: Editorials, Review Articles, Research Articles, Short Communications, and Letters to the Editor.

Editorials: These will be written by invitation only, and will be on topics deemed to be important by the editorial board of the journal.

Review Articles: Authoritative reviews will be published both from invited experts and by direct submission. In both cases, the work will be subject to editorial review. The review article should include critical reviews of important areas of environmental engineering in order to inform the general reader of the background, the state of the art, and outstanding research problems.

Research Articles: Original findings pertaining to the scope of the journal will be published after peer review. Full-length research papers should describe important new experimental or theoretical results and implications.

Short Communications: Short communications are short reports that describe briefly a piece of work not sufficiently comprehensive to make it worth a full article, and that develop the essence of a new experimental or theoretical concept, present new experimental data, elaborate on a previous journal article, etc.

Letters to the Editor: Letters to the editor may be submitted on any subject of interest to the journal readership. Letters commenting on previously published articles will normally be sent to the authors of the previous publication for possible response prior to publication.

RESEARCH AND PUBLICATION ETHICS

For the policies on research and publication ethics that are not stated in these instructions, the Core Practices (http://publicationethics.org/corepractices) are applied.

Conflict-of-interest statement: If there are any conflicts of interest, authors should disclose them in the manuscript.

Authorship: Authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data, 2) drafting the article or revising it critically for important intellectual content, and 3) final approval of the version to be published. Authors should meet these 3 conditions. No changes of authors are allowed after the acceptance of a manuscript.

Originality and Duplicate Publication: All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. No part of the accepted manuscript should be duplicated in any other scientific journal without the permission of the Editorial Board. If any duplicate publication related to a paper of this journal is detected, the authors will be announced in the journal and their institutes will be informed, along with retraction of the paper.

PEER REVIEW PROCESS

Submitted manuscripts will be reviewed by two or more experts in the corresponding field. The Editorial Board may request that authors revise the manuscripts according to the reviewers' opinion. After revising the manuscript, the author should upload the revised files with a reply to each item in the reviewers' comments. The author's revisions should be completed within 30 days after the request. If it is not received by the due date, the Editorial Board will not consider it for publication again. To extend the revision period to more than 30 days, the author should contact the Editorial Board in advance. The manuscript review process should be finished after agreement of reviewers and editor. If the authors wish further revision, the Editorial Board may consider it. The Editorial Board will make a final decision on the approval for publication of the submitted manuscripts and can request any further corrections, revisions, and deletions of the article text if necessary. Statistical editing may be done if the data need professional statistical review by a statistician. Finally, the revised manuscript should be submitted within 1 week of the request. The review and publication processes that are not described in the Instructions for Authors may follow the Editorial Policies approved by the Council of Science Editors (http://www.councilscienceeditors.org/resource-library/editorial-policies).

COPYRIGHTS AND CREATIVE COMMONS ATTRIBUTION LICENSE

Copyrights of all published materials are owned by the KSEE. They also follow the Creative Commons Attribution License (http://creativecommons.org/licenses/by/3.0/).

PAGE CHARGES

The cost of article publishing charges will be covered by the KSEE and so there are no publication fees for authors. An author’s personal copy of the article (in a PDF file) will be provided free of charge as well. Offprints will be ordered separately at a cost of KRW 20,000 (or US$ 20) for thirty copies.

ELECTRONIC SUBMISSION OF MANUSCRIPT

Manuscripts should be uploaded electronically via the online submission system at http://submit.eeer.org/. Authors will be notified as soon as their manuscript reaches the editorial office. Authors should receive an email acknowledgement after confirming submission. If no acknowledgement is received, the corresponding author should contact the EER editorial office at eer@kosenv.or.kr.

MANUSCRIPT PREPARATION

Manuscripts should be submitted in the file format of Microsoft Word 2003 or higher. Manuscripts should be formatted in A4 size, double-spaced, using a font size of 10 or larger with margins of 2.5 cm on each side and 3 cm for the upper and lower ends. Number pages consecutively, beginning with the title page. Page numbers should be placed at the middle of the bottom of each page.

There is no fixed maximum length for full-length articles, but they rarely exceed 30 double-spaced, typewritten pages (or 10,000 words) on 210×297 mm (A4 size) including figures and tables. Short communications have page limits of 4 printed pages (or 4,000 words). The arrangement and format for full-length or short articles are described below.

Title Page: The title page should include the full title of the article, authors’ names, positions, affiliations, and footnotes. The title should emphasize the principal objectives covered by the paper. Authors’ names should consistently and preferably be written in a standard form for all publications to facilitate indexing and avoid ambiguities. If some of the authors have different affiliations, use numbers as superscript 1, 2, 3… after the surname of authors and before the name of their affiliations. Use a dagger (†) after the name of the corresponding author. If two or more co-authors are equal in status, they should be identified by an asterisk (*) with the caption ‘These authors contributed equally to this work’. The contact information for correspondence should include the e-mail address, telephone, and fax numbers.

Abstract & Keywords: The abstract should state the objectives and present salient conclusions in no more than 200 words. It has to be a clear, concise summary describing scope and purpose, methods or procedures, significant new results, and conclusions. The abstract should be written as one paragraph. At the end of the abstract, keywords should be given in 3 to 6 words or phrases.

Introduction: The article should begin with an introduction that is written for the general reader of the journal, not for the specialist. This section should include the background and objectives, together with significant prior works.

Experimental Section: The research article should include experimental methods (or materials and methods). The experimental section should describe the techniques utilized in the investigation, making clear the protocol of the study. The manufacturer, model number, and sensitivity of monitoring equipment or chemicals should be stated in this section. Where appropriate, any statistical tests should be described and supported by a reference to the original citation of the test.

Results and Discussion: The results and discussion section may be combined into one section. Results in research articles should be the description of what was found with appropriate numerical support. If there is a series of steps in an investigation, the authors may find it convenient to present their text under a number of sub-headings. For review papers, the author may choose the format best suited to the paper. Writing should be concise, eliminating details that are not essential to the development of the review and are readily available in previously published papers or accessible reports. Text should be sectionalized by inserting appropriate headings.

Conclusions: The conclusions section should highlight key findings and compare the results of the work to appropriate findings of other studies. The conclusions should be based on the evidence presented in the results and discussion section.

Acknowledgments: The Acknowledgment section is placed after the Conclusions section. Please provide information about funding by including specific grant numbers and titles at the time of submission if needed.

Author Contributions: Contribution of each individual author to the article should be mentioned as a single sentence, along with the author title or status: e.g., G.D.H. (Ph.D. student) conducted all the experiments.

Nomenclature: Symbols used in the text or in equations should be collected and identified in a table of nomenclature with definitions and dimensions near the end of the paper prior to the references section. Roman symbols should be listed alphabetically in the table first, followed by Greek symbols. The symbols should be those commonly used in environmental engineering.

References:
References must be numbered consecutively in order of first appearance in the text and should be given in a separate double-spaced list. Reference citations in the text should be identified by numbers in square brackets. Some examples:

- Negotiation research spans many disciplines [1].
- This result was later contradicted by Cho [2], Kim and Lee [3], and Choi et al. [4].
- This effect has been widely studied [3-6, 7].

The list of references should only include works that have been published or accepted for publication. Personal communications and unpublished works should only be mentioned in the text. List all authors if there are six or fewer authors. List the first three authors followed by "et al." if there are more than six authors. Lines after the first line of a reference are indented by one character space. An example of the correct citation format for an article in EER is as follows:

Journal article

Book

Conference paper

Dissertation

Website

Figures & Tables: The total number of figures and/or tables for each manuscript is limited to 8. Further display items can be provided online as supplementary materials. Figures and tables (both numbered in Arabic numerals) should be prepared at the end of manuscript or separately. For captions, put a period at the end for figures, and do not put a period at the end for tables. For the reproduction of figures, only good drawings and original photographs can be accepted, but negatives or photocopies cannot be used. It should be of sufficient size so that after photoreduction to a single column width (8 cm) the smallest letter will be 2 mm. Legends should be placed in the white space of the drawing, not in the caption. Photographs can be accepted for an additional charge if essential to the paper. If two or three figures are shown in stack and abscissas are the same, use only one abscissa with different ordinates. If ‘pie’ or ‘bar’ charts are to be shown, use patterns for different pie slices or bars instead of color.

Supplementary Materials: Supporting data can be uploaded online and will be available for peer review and readers. Use a common data format for easy access of readers. The maximum size of files for supplementary data should not exceed 10 MB. If they are too big, please contact the editorial office in advance.
Supplementary materials must have a separate numbering system and should be labelled properly, e.g., Figure S1, Table S1, and so on. Video and audio files should be provided separately and have a title each. They should be referred to at least once in the paper at an appropriate point in the text.

REVIEW ARTICLES

Review articles may be solicited or submitted. Previously published material should be incorporated into an integrated presentation of our current understanding of a topic. Topics of scientific consensus as well as topics that remain controversial may be dealt with in the reviews. A review is organized as follows: title page, introduction, body text, conclusion, acknowledgments, references, tables & figures, and figure legends.

LETTERS TO THE EDITOR

Letters to the editor should include brief constructive comments that concern previously published articles and interesting cases. Letters to the editor should be submitted no more than 3 months after the paper has been published. Title pages should be formatted as those of research papers. The body text should not exceed 500 words and should have references. Letters may be edited by the Editorial Board, and if necessary, responses by the author of the subject paper may be provided.

GENERAL TEXT STYLE

Statistical Expression: Mean and standard deviation should be described as mean±SD, with mean and standard error as mean±SE. P values should be described as p < 0.05 or p = 0.003.

Units: The SI system must be used for all dimensional quantities. Specifically, use 's', 'min', 'h', and 'd' for time units. Use one space between unit and number except %, °, °C. Be sure to use 'mg/L' instead of 'mg/l'. All equations should be numbered in Arabic numerals.

GALLEY PROOFS

Unless otherwise indicated, galley proofs are sent to the corresponding author and should be returned within 48 h. No significant alterations should be made in galley proofs, other than the correction of typo errors.

PUBLICATION DATE
