Dr. Park, professor in the department of Biochemistry, Medical School, published the research result in Redox Biology (February 2020)


The research team of Dr.Park Jae-Bong at the Department of Biochemistry, School of Medicine, published the research result in the online edition of the internationally renowned academic journal “Redox Biology” in February 2020. Cap Kim Cuong, graduate student from Vietnam in Medical Science, conducted this research under the lead of Dr. Park. The research identified different signaling pathways according to the concentration of amyloidobeta in neurons. Professor Sangwon Seo from Hallym University School of Medicine, Professor Wonseok Won at KAIST and Professor Hoon Ryu KIST also participated as co-researchers.


One of the typical symptoms of Alzheimer's dementia, amyloid plaques are formed on the outside of nerve cells and tau proteins are entangled inside the nerve cells to damage the nerve cells. It is known that amyloid beta phosphorylates tau protein, but the mechanism is not well known. The research results show that low concentration of amyloid beta rather promotes the phosphorylation of tau protein, while high dynamic concentration of amyloid beta rather does not promote the phosphorylation of tau protein, but makes a lot of active oxygen and inducing liposynthetic enzyme and finally increase it.


This research result proved that, due to a large amount of amyloid beta, there are candidate drugs for dementia treatment that inhibit amyloid plague or amyloid beta formed outside nerve. It is still a threatening factor to nerve cells if there are low concentration of remaining amyloid beta, therefore it is more effective for Alzheimer's dementia treatment to block the signaling pathway of amyloid beta in nerve cells rather than remove the amyloid.

Dr. Chan Park, professor in the department of Medical Science, published theses in the SCIE-level international journal (February & August 2020) 

※ Olatunji Abolarin Ajiteru (graduate student in Molecular Science from Nigeria) was in the team

The research team led by Dr. Chan Park (Otorhinolaryngology, Nanobio Regenerative Medicine Research Center) accomplished a feat of publishing three theses in the SCIE-level international ‘Nano Letters”(IF: 11.238, top 7%) and “Biomaterials”(IF: 10.317, top 1%).


3D bioprinting is a main technology that is the basis of the fourth industry, such as producing patient-oriented implants or developing organ-on-a-chip using materials (bioink) capable of 3D printing including cells. Since the professor's team announced the development of silk-based bioink in Nature Communication in 2018, the range of application of silk bioink has been expanded through progressive research. 


Through a photolithography printing technique, they created a structure very similar to a real trachea and implanted the silk bio-ink into a damaged organ of a rabbit. They derived excellent biocompatibility and organ regeneration results, and this was published in the world-privileged journal “Biomaterials”. (February 2020)


In August 2020, they published the research results on the 4D bioprinting in the identical journal. The 4D bioprinting is a 3D printing technique which has first a 2D structure and then assembles again in 3D into a desired shape over time based on a specific stimulus. This technique was used to fabricate organs to transplant to a damaged ones of a rabbit. With this technology, it is now possible to create complex shapes such as flowers or fly hell, and we expect to overcome the existing printing limitations. 

Additionally, in order to produce a structure for culturing nerve cells, the professor's team developed a bio-ink which contains electrical conductivity, biocompatibility, and printability by using a silk-bonding conductive graphene oxide. This was published in another world-privileged journal “Nano Letters”. (August 2020)


The developed bioink promotes the activation of nerve cells and exhibits high electrical conductivity, so it is expected that it can be utilized as a material for various nerve regeneration such as for central nerve, olfactory nerve, optic nerve, and peripheral nerve.


Eventually the professor has been featured more than three times as one of the people who brightened Korea by BRIC. Currently, he is focusing on his research on the usage of various natural materials, including silk, stem cell delivery system, laryngeal regeneration scaffold, hemostatic agent, artificial skin, blood vessel-based cancer metastasis platform development, as well as obtaining stem cells from the discarded tonsils.

Moh Moh Thant Zin, graduate student in Environmental Bio-Engineering, published a thesis in the SCIE-level international journal (August 2020)

 Moh Moh Thant Zin (Adviser : Professor Kim, Dong-Jin) published, as the lead author, a thesis in the SCIE-level international ‘Journal of Hazardous Materials’. Her research proved that, when phosphorus and nitrogen contained in food waste and wastewater are combined with biochar, it can lower water pollution and be used as fertilizer. Biochar is a compound word of Biomass and Charcoal, and refers to a soil conditioner made by burning coffee or wood into charcoal powder. Biochar is a resource for producing courses that have a positive effect on water and soil while reducing the amount of carbon dioxide and has been evaluated as the best carbon reduction technology.


Moh Moh Thant Zin is from Myanmar. She’s got Bachelor of Pharmacy and Master of Environmental Engineering at Asian Institute of Technology (AIT) in her home country. She was selected as a GKS student for a Doctor’s degree program and has started to study at Hallym University since September 2016. She is expecting her graduation in coming August. Her main research areas are the production of biochar with biomass for surface modification; recovery of resources such as nitrogen and phosphorus from wastewater using functional biochar; evaluation of the bioavailability of the recovered resources.


‘Journal of Hazardous Materials’ is a SCIE-level international academic journal in the field of the Environmental engineering with an IF(Impact Factor) of 9.038, an index representing the journal’s perceptual index based on the 2019 JCR.

Seong Yoo, undergraduate student in Japanese Studies, has got the scholarship of the Japanese government funding (October 2020)

Seong Yoo, fourth year student enrolled in the Department of Japanese Studies, was selected as scholarship research-students in terms of Korea-Japan Joint Higher Education International Student Exchange Program (1-year course). Organized by Japan's Ministry of Education, Culture, Sports, Science and Technology.


 This International Student Exchange Program is a newly implemented program to expand mutual exchange between Japanese and Korean students, and selected in total 25 people. This program is a changed form of the “Japanese Language and Culture Trainees” program operated by the Japanese government from 1979 until last year.


Seong Yoo who was selected as international research-students will receive tuition waiver, round-trip airfare, and a monthly scholarship of 117,000 yen (approximately 1.77 million won) while studying at Tohoku National University in Japan for one year. He will also participate in advanced sessions of learning Japanese language and culture. 


The international student who receives the governmental funding is subject to quite a long selection process; document screening, written examination (first announcement), research plan, interview (second announcement), evaluation of the research plan, check for personality and academic will, admission to the desired university, and final approval by the Japanese government. The competition is very fierce every year due to the incomparable scholarship benefits.


"I have been selected before as an outgoing exchange student of Hallym University and studied at Tohoku Fukushi University and Niigata University for a total of 1 year, and I think this experience came to a good result. I sincerely thank my professors and Hallym University International Office (ISSO) for all their hard work and support." said Seong Yoo.


Hallym University's Department of Japanese Studies has produced so far 11 students selected in this Japanese funding program and continues to contribute to cultivate experts in regions of Japan.
