Co-author of a medical treatise, the first author of the country's daughter, Cho Mo, the daughter of the former Minister of Justice, testified in court that there was no "Joe's contribution."

Hyun Mo, who was a researcher at the Institute of Medical Sciences at Dankook University at the time, said as a witness to the follow-up hearing of Professor Chung Kyung-Shim of the University of Oriental Medicine held at the Seoul Central District Court's 25-2 Division Criminal Agreement (Jung Seop Soo, Kim Seon-Hee, Deputy Justice Judge Kim).

The prosecution confirmed that Professor Chung asked Dankook University, Jang Young-pyo, the father of his daughter Young-go's friend, a young and old high school friend in July-August 2007, and found that Jo had been active in the Dankook University Medical Science Research Institute for two weeks and was registered as the author of the thesis.

In the following year in the Korean Journal of Pathology, Mr. Cho was the first author in an English paper titled 'Polymorphism of vascular endothelial nitric oxide synthase gene in post-partum ischemic hypoxic encephalopathy (HIE)'.

The prosecution believes that Professor Jang has made Mr. Cho the first author and made false confirmations so that he can use it for college entrance exams.

Prof. Chung and Mr. Cho submitted this to the Seoul National University Graduate School of Medicine in 2013.

Hyun is one of the co-authors of the paper.

He testified that the experiment related to this paper was entirely done by Professor Jang.

Next, the prosecutor asked, "Did you ask about the contribution of Mr. Cho's thesis from Dankook University's Research Ethics Committee and answered 'No'?"

He also replied that Mr. Cho claimed that he had "driven the experiment" during the prosecution investigation, that he had "no time or skill to lead the experiment for two weeks."

Hyun said that it was true that Mr. Cho had been engaged in a two-week experience at the time, but he was more than just a field trip and following simple tasks rather than participating as a researcher.

He said, "I did not write the experimental data (extracted by Mr. Cho) in the paper".

He didn't even tell Mr. Joe how to classify the extracted results and write them as data, he explained that he did it entirely.

On the other hand, Professor Jeong's lawyer said that the documents that Professor Jang issued to Mr. Cho at the time were not a research report, but a confirmation of 'experience activity'.

The lawyer also claimed that the experiment was manual, so that the expression of Mr. Cho's evaluation was not wrong with the expression 'to some extent possible'.
