An engineer in South Korea has lost 30 papers, at least seven of which for duplication and plagiarism. He has also been fired from his university position.
Soon-Gi Shin, whose affiliation was listed as Kangwon National University in Gangwon, is the sole author on the majority of the papers, published in four journals between 2000 and 2015.
Taewan Kim, the dean of international affairs at the university, told Retraction Watch that Shin was fired on August 21, 2017, over “violation[s] of research ethics.”
The papers explore the electrical properties of various materials composed of metal, glass and plastics.
Last month, two Springer journals—Metals and Materials International and Electronics Materials Letters—retracted seven of the Shin’s papers. The other 23 papers were retracted by the Korean Journal of Metals and Materials (KJMM) and the Korean Journal of Metals and Research. It’s not clear when these 23 papers were retracted; we found the papers watermarked “retracted,” but did not find an accompanying notice or date of retraction.
Do Hyang Kim, editor-in-chief of Metals and Materials International, told us that the issues with Shin’s work were first detected by KJMM, which retracted nine of his papers last year. Kim explained that the retractions in KJMM prompted the other journals to examine Shin’s work.
The notices in Metals and Materials International, which retracted four papers, and Electronics Materials Letters, which retracted three, all cite “substantial duplication” and “overlap” with previous work by Shin and others.
Shin, however, lost the bulk of the now-retracted papers—14 in total—from the Korean Journal of Metals and Research; these 14 papers, along with the nine retracted by the Korean Journal of Metals and Materials, do not appear to be accompanied by a notice or date of retraction.
Here’s a notice for a 2011 paper “Effect of carbon content on the electrical conductivity of carbon black-filled pmc with various matrices,” in Electronic Materials Letters:
The Editor-in-Chief and Editorial Board of Electronic Materials Letters have retracted this article  because its contents have been previously published by Miyasaka et al. . The contents of this article are therefore redundant. Author Soon-Gi Shin has not responded to correspondence from the Editor about this retraction.
Seventeen of the now-retracted papers were indexed by Clarivate Analytics’ Web of Science; collectively those papers have been cited 70 times.
Kim explained that Metals and Materials International did not catch the plagiarism and duplication during peer review because the four articles in question were published more than 10 years ago, when plagiarism detection software was not available.
The software, however, was available when most of the 26 other retracted papers were published. We contacted the editors of the three other journals as well as Springer, which publishes Metals and Materials International (MMI) and Electronics Materials Letters (EML). The only contact information we could find for Shin was his email at Kangwon National University, but he has not responded.
When we asked Do Hyang Kim whether there were more retractions to come for Shin, he told us:
We have examined all the papers in MMI and EML.
This is not a record number of retractions for one person; as of today, 11 people on our leaderboard have more than 30 retractions each.
Update, 2000 UTC, 3/16/18: Springer told us:
The investigations into the articles published by Soon–Gi Shin in Metals and Materials International and Electronic Materials Letters were triggered by retractions in the Korean Journal of Metals and Materials and concerns expressed by a whistleblower. This came to our attention in the summer of 2017.
