‘Dankook ranks 6th in universities with the most graduates serving as CEOs of a top 100 business’ rated by the Korea Economic Daily Business Magazine (Hankyung Business) Three Dankook graduates were found to be serving as the chief executive officer (CEO) of a top 100 business in Korea. Among universities that have graduates in the CEO post of a top 100 company, Dankook ranked in 6th place. In the cover story of the 1,230th edition (Jun 24~30, 2019) of the Hankyung Business magazine, three CEOs among the leaders of the top 100 businesses in Korea were Dankook alumni – Han-woo Park (Department of Business Administration) at Kia Motors (8th), Do-jin Kim (Department of Economics) at IBK Bank (48th), and Il-moon Jung (Department of Business Administration) at Korea Investment & Securities (85th). Hankyung Business stated that the top 100 companies were selected based on revenue and net profits and introduced the profiles of each company’s CEO. While the named DKU graduates have frequently been in the media spotlight, most recently, IBK president Do-jin Kim became Chair of the ‘Department of Economics’ Scholarship Foundation’ and delivered 105.84 million KRW in scholarship funds to current students last May. Il-moon Jung, who was the first publicly recruited employee to become CEO of Korea Investment & Securities, has also recently been in the media often. FN Guide, which provides financial information services, reported that, following Jung’s appointment, Korea Investment & Securities is forecast to see a 20% increase in revenues compared to the previous year.

Professor Jin-ho Choy and his research team at the Institute of Tissue Regeneration Engineering have developed a bio-transplantation device that delivers drugs through near-infrared radiation without the use of needles. The outcome of the joint research with professor Young-bin Choy of Seoul National University was published in the global scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States of America) on May 23, 2019. The device developed by professor Choy’s team is a transplantation device that enables the administration of drugs through an external application of near-infrared radiation to overcome the difficulties faced by patients who experience pain or a financial burden from repeated subcutaneous injections. The device implants several sealed drug reservoirs in the skin that release doses one at a time when near-infrared rays are directed at them. With a single implant, patients can administer the drugs whenever necessary by exposing the skin for a short period (around 5 seconds) to near-infrared radiation. It is small and does not require batteries or a separate power device, making it convenient for transplantation. The core technology in this research is the ‘responsive membrane that ruptures from near-infrared radiation’ which was developed by the Institute’s professor Go-eun Choi and researcher Hye-yeon Park. The key technology of the device in the limelight is a hybrid membrane made of graphene-based nanoparticles and special polymers. “It is a new concept medical device that can significantly ease the inconveniences undergone by patients suffering from chronic diseases who require repeated drug injections over long periods,” said professor Jin-ho Choy who went on to explain that “it will be a breakthrough for patients with short stature caused by deficiency in growth hormones or those suffering from type 1 diabetes.” The research was carried out with support from the Ministry of Science and ICT, and the National Research Foundation’s NRF Special Cooperation Program and Basic Research Program (mid-career research program).

As 2018 came to an end, efforts to give to those in need continued during the holiday season. On Monday, December 31 of last year, Byung-ryang Kim, Senior Vice President for Academic Affairs and Provost, visited Yongin’s city hall to donate 50 boxes of ramen, worth around 1 million KRW. Vice President Soo-bok Kim of the Cheonan Campus also delivered 100 boxes of ramen, worth approximately 2 million KRW, to Cheonan’s city hall the week before on December 24. The donations of instant noodles will be delivered to low income families based on demand surveys carried out by each respective city government. “The ramen donations were special orders given by DKU president Hosung Chang in order to practice the university’s educational direction of truth and services and share growth with local communities,” said Vice President Byung-ryang Kim who added that “[we] will strive to become a university that takes the initiative in being there for those in need and extending a helping hand.” In November, volunteer corps at Dankook’s two campuses also took part in preparing kimchi and delivering coal briquettes to basic livelihood security recipients and senior citizens living alone to help them get through the cold winter. On November 9, the Jukjeon volunteer corps and student council visited basic livelihood security recipients and the elderly living alone in Yongin city to deliver four thousand coal briquettes and 80 kg of rice to eight households. The Cheonan campus volunteer corps and student council spent November 23 making kimchi for the local community, completing one thousand heads of kimchi cabbage to share. The winter kimchi project has been ongoing for years with around 60 students and faculty members joining in this year. The kimchi made was donated along with two thousand kilograms of rice to the Cheonan Welfare Center for the Disabled, the Chungnam Welfare Center for the Visually Challenged, welfare centers ‘Beautiful House’ and ‘Warm Nest’, and the Kiun Up volunteer group and Dogwangsa temple which operate free meal stations. “I’m sure there was room for improvement, it being my first time making kimchi, but it was worthwhile thinking that the kimchi I made may be fulfilling for someone in need during the winter. I hope I can take part again next year,” said Yong-deck Kim (Industrial Engineering, Junior). On November 30, the Cheonan Campus faculty volunteer corps helped out at the ‘Beautiful House’ welfare center for the severely mentally challenged located in Buk-myeon, Cheonan city.

Three diagnosis patents using 'biosensor combining optical fiber, gold nanoparticles.' Groundbreaking change expected in the field of cancer diagnosis Strong potential of commercialization with biosensor diagnosis technology that can be applied to various cancers in addition to prostate cancer A Dankook University research team is in the spotlight for its development of a biosensor that raises prostate cancer detection rates by more than a hundredfold compared to current levels. The team is led by Professor Seung-ki Lee and Professor Jae-hyoung Park along with researcher Hyeong-min Kim of the Department of Electronics and Electrical Engineering. The biosensor developed by Professor Lee’s team is made of a structure where gold nanoparticles are attached to the surface of optical fibers on top of which a microfluidic chip is added. Blood is dropped onto the biosensor where the prostate cancer antigens blend with antibodies on the surface of gold nanoparticles and send a specific optical signal which enables diagnosing whether cancer has occurred or not. According to the research team, the new biosensor is forecast to trigger innovation in the field of prostate cancer diagnosis as its ability to detect antigens is 100 times more effective than existing equipment, not to mention having a shorter testing time of only 5 minutes. The diagnosis error factor also drops from the current 10~15% to 4%. According to professor Lee, “the antigen reaction takes place along optical fibers with ultra-thin diameters of 250㎛ (micrometers), detecting 124fg [femtogram, 1fg refers to 10-15 g (10 to the power of negative 15, 1 in 1 quadrillion grams)] of antigens in 1ml, proving the excellence of the diagnosis technology.” In other words, optical technology comes together with biosensors and nano technology. Professor Lee explained that “while prostate cancer is the 5th most common cancer among Korean men, treatment becomes very expensive if not diagnosed early on,” and added that “the newly developed biosensor can be commercially produced at around 2~3,000 KRW, attracting the attention of domestic and foreign medical equipment players.” Currently, prostate cancer is diagnosed by 1) measuring prostate specific antigen (PSA) protein levels in blood·urine, 2) digital rectal examination (DRE), 3) prostate ultrasound, and 4) biopsy. Among them, the biosensor developed by Professor Lee’s team is based on the PSA protein measurement method. “This technology is reliable for clinical feasibility,” says Professor Lee who added that “the biosensor technology will be able to be used not only for diagnosing prostate cancer but also for detecting various other cancers that react to antibodies.” This study was carried out with the support of the National Research Foundation of Korea’s Promising Future Convergence Technology Pioneer Program and the Mid-career Researcher Support Program. In addition to developing the biosensor, the research team completed applications for and registered three patent licenses: a surface plasmon resonance sensor device and sensor unit manufacturing method using microfluidic channels, a surface plasmon resonance sensor signal correction method, and a surface plasmon resonance sensor testing method. The research outcome was published in the international academic journal Sensors and Actuators B on November 10.
