   Some people in Dongguk University(DU) believe that the Department of Science and Engineering is inferior to the Department of Liberal Arts. The reason for this prejudice is that the College of Liberal Arts has several famous writers and every year its students win prizes in the spring literary contest. But aren't there any notable achievements in the Department of Science and Engineering? Let's find out.

   Earlier this year, DU was selected as TLO for a national policy study by the Ministry of Education, Science and Technology. TLO means by Technology Licensing Office (or Organization) which helps a university created product to get marketable. At present, there are eighteen TLO universities in total, with seven in Seoul including DU. Each University is valued from A to C gradient. DU now has financial support for two years - the total of which is 400 million won approximately.

   Being selected for a TLO means that, in the future, the DU brand stock will be known to many companies; it also means that the needed funding will be available. This is a great opportunity to profit from the ingenuity of students and professors; the money accrued from these products will, in turn, create a better infrastructure.

   In the meantime, DU's Science and Engineering department will continue to work on the national policy study which is supported by, among others, the Ministry of Knowledge Economy, the Korean Science and Engineering Foundation and the Korean Institute of Industrial Technology, Evaluation and Planning.





Quantum-Functional Semiconductor Research

   The Post met Kang Tae-won, a professor at Department of Physics, who is also director of the Quantum-Functional Semiconductor Research Center.


The Post : Please tell us about your project


Kang Tae-won

 Kang Tae-won (Kang) : SRC is, approximately, a one billion won project supported by the Ministry of Education, Science and Technology. We are involved with Quantum-Functional Semiconductor Research. It is very interesting and commercially profitable.  This project is evaluated every three years. Each year, DU has attained an A grade. Everyone is very impressed by these great results. Last February (2009), the project came to an end, but because DU was in the top 30percent, there will be a further 500 million given to DU over the next five years. In addition, the American company  Novakor will also provide 5 million dollars (about 6,500,000,000 won) a year. This is the highest funding made ever by a foreign company.

The Post : What is a Quantum-Functional Semiconductor?

Kang : In short, a Quantum-Functional Semiconductor has two special features: 1) it has more memory space and 2) it is smaller than other models.

The Post : How have you made it commercially competitive?

Kang : It is very applicable to nano-technology, especially the IT industry. Current computer models have only a Giga Byte memory(109). In our model, the size of memory has increased by 2n. But if the Quantum-Functional Semiconductor is successfully devised, we can increase the memory by nn - this would actuate perfect artificial intelligence. The key point is to realize that the size of the computer memory and its speed grow dramatically.  This project has been reported in the Dong-A Daily News, Joong-Ang Daily News, Cho-Sun Daily News, and other newspapers. It also was reported in the cover story at the worldwide Journal APL, and has been frequently mentioned elsewhere. The technology is so innovative that twenty-four patents have been applied for.

The Post : What is the hardest thing to do in this project?

Kang : This technology tries to ally cutting-edge research with commercial nous. It is a very hard thing to do. But I am able to create things which are both theoretically and commercially viable.

The Post : What is your future plan?

Kang : In the short term, I want to replace fluorescent lamps with a light-emitting display unit. This can cut energy output by about 85percent while increasing durability fifteen times more. It also takes out the poisonous mercury constituent; thus reducing pollution and damage to the environment. In the long term, I want to make a quantum computer. As I said earlier, if a quantum computer can be created, a computer's potential to store artificial intelligence shall be infinite. For myself, I plan to theorize my thesis and present it at the international scientific journal, Natural Science.



The Nano-New Material Ionized Yellow Earth by DURIB

   Interesting projects are also in progress at the Dongguk University Research Institute of Biotechnology (DURIB). This institute is developing nanotechnology - new material processes from natural minerals. The natural minerals have a strong anti-fungal absorption rate due to their alkaline content. The ionized yellow earth process material is produced by natural minerals and alkaline material. It begins to melt between 1400degrees and 1600degrees. After this, it is cooled and pulverized. This technology holds five patents.

What Is the Commercial Potential of This Technology?

   The first thing is its use for the cosmetics industry. The ionized yellow earth process material can treat skin diseases such as dandruff, acne and athlete's foot. The global turnover for the cosmetics market (for 2007) was about 140 trillion won, while its domestic turnover was around 5.5 trillion won. The expected growth rate is 10percent annually. As you can see, it is a highly profitable business. The soap that is made by the aforementioned natural minerals contains sixteen traditional ingredients. It was tested for four weeks: the test showed that it can be used for skin treatment.

   The second thing this department is working on is the creation of a soil-friendly recycling system through the use of yellow earth. It can increase harmless microorganism by spraying the atmosphere with ionized natural minerals and soil-friendly microorganisms. In the DU experimental farm, researchers have made a comparative study between a sprayed radish and unsprayed cabbage. They observed the recycling of microorganisms once a week. In consequence, sprayed radishes and cabbages grew quicker with increased minerals.

   The third thing is that the quality of the sprayed yellow earth improves; this, in turn, prevents the occurrence of red tides. The problem is that existing agriculture loses 50percent of its product to soil erosion, water pollution, and plant disease. In addition, fish and shellfish suffer from a toxicity that is very difficult to measure.

   The prevention of red tide is made by pure silicon dioxide and nano-colloid ionized yellow earth. This has an effect of decrease to use yellow earth, and the efficiency is getting better. Because of this technology, a cost of the sprayed yellow earth can be ecologically beneficial. Also, it can save the management expenses and spraying cost.

   In the DU International Hospital, there is a promotion of health program. With the help of National University of Mongolia, DU make functional beverage, cosmetic and soap by using fruit of vitamin tree. Korea-Mongolia international symposium where officials are planned to discuss the development of the site of the vitamin trees will be held on 2009. Aforementioned land for vitamin trees will be alloted about 200,000ha. A scale of market is expected to be 260 million dollars for Organic food, 9 million dollars for the prevention of red tide, and about 320 billion dollars for cosmetics in 2010. DURIB could get good result because it is expected to earn about 367 billion dollars.


A Millimeter Wave Semiconductor Chip for Radar

   On March 19th, the Agency for Defense Development, Hanwha and the Millimeter-wave Innovation Technology Research Center (MINT), under the auspices of DU Professors Rhee Jin-koo, Kim Mi-ra and Chae Yeon-sik, announced that they had invented a One-Chip MIMIC for a FMCW radar receiver that is able to operate in a millimeter-wave sphere. It will be first introduced in Korea. Millimeter-waves are frequencies between 0.3 GHz and 300 GHz. They are used for special technology such as satellites and military weapons. This semiconductor chip has a low-noise amplifier with a frequency mixer for the restoration of a signature. So the size of the chip is smaller than it used to be. The low-noise amplifier and frequency mixer will be mass-manufactured. The size of the newly invented play panel is 3.3mm×2.5mm. It will be used for making a millimeter-wave sensor module. This invention has great significance for the localization of millimeter-wave display panels and the discovery of new technology.

   Prof. Chang Wins a Presidential Commendation

   Jang Yeon-soo, a DU Civil & Environmental Engineering professor, won a presidential commendation on Civil-engineering day, March 30th. He supervised about 80 graduate students in their doctoral and master courses and read several excellent papers on Geo-environments and Geo-technical Engineering at home and abroad. When he worked at the Korean Institute of Construction Technology, he did research on the utilization of reclaimed land and the strengthening of weak soil. In many ways, he has contributed significantly to the development of this country's Civil and Geotechnical Engineering. He also worked for Ministry of Land, Transport and Maritime Affairs project which seeks for developing educational systems for the construction department and for the construction environment in industry. He was a chairperson for two years on the Dredging & Reclamation committee and worked for one year on geotechnical environment technology at the Korean Geotechnical Society. He has also worked as a technology development lecturer and sat as a member for an advisory committee for the country's major ministries and offices - the Ministry of Land, Transport and Maritime Affairs, the Ministry of Environment and so on.




Capstone-Design Fair 2008


Cho Seung-pyo, Lee Jeong-bok

   Cho Seung-pyo and Lee Jeong-bok, DU Computer Science students, won a Korean Accreditation Board Engineering Education Prize at the Capstone Design Fair held from November 6th to 8th, 2008. The Capstone Design Fair is a competition in which engineering department students from around the nation participate. Cho Seung-pyo and Lee Jeong-bok's team's name was "Sparta" and they exhibited a "Computer control program using hand interface." It was a prizewinning work. They used image processing technology to create their exhibit. The camera recognizes a data image of a hand and a mouse then points to the tip of the index finger. They researched data on the different color pigmentations on a human hand. This technology can be utilized to make touch-screen electronic products. They said that they benefited greatly from DU's ABEEK program.




The Civil Engineers's Day Competition

   Bae Man-hyung and four other students majoring in Civil & Environmental Engineering won third prize in the Civil Engineer's Day Competition on March 30th, 2009. Another DU student also won the first prize in this competition in 2008 and one of our students repeated the same history by winning the prize again. Bae Man-hyung and four other students constituted a team named "Lucky 7" and displayed "Ocean's Bluechip" at the competition. This is the engineering structure that can supply electric power by using the force of a wave and the structure of a breakwater. They designed the structure of a breakwater to generate power. By doing this, they could utilize the force of the wave more efficiently and minimize the loss of power. It is able to operate constantly, regardless of the weather, as it uses waves as a source of energy. A complex system which mixes the force of the wave and the collision of piezoelectric elements was used in the creation. It will be an efficient alternative energy resource, sustainable and environmentally friendly in case of energy crisis.





The Millimeter-wave Innovation Technology Research Center(MINT)


Rhee Jin-koo, Kim Mi-ra and Chae Yeon-sik

   Since 1997, the government has chosen MINT as an Engineering Research Center (ERC); it is part of the many nationwide projects which aim to improve national competitive power in science. The head of MINT is Professor Rhee Jin-koo. MINT gets financial support approximately a billion won from KOSEF, and approximately 100 million won from DU. KOSEF and DU also give funding for clean, efficient research on the making of semiconductors.

   Millimeter-wave (30~300 GHz) is usually used in communications technology. Wave-research is still at an undeveloped stage, so there are still many areas to be explored. Drs. Kim Mi-ra and Chae Yeon-sik are leading the major research. Dr. Kim Mi-ra's research is on millimeter-wave sources and is supported by Eltronicx. Dr.Chae Yeon-sik's research is on millimeter-wave imaging systems and is supported by Eltronix and the Seoul Development Institute.

   One of the purposes behind their research is the development of a "Smart-bomb" which has millimeter-wave sensors. This project is supported by the Agency for Defence Development and Hanwha. The research achievements of MINT have attracted the spotlight and have been profiled by several international journals, including America's "IEEE."

Nano-bioDiagnostic Research

   Prof. Kim So-youn in department of Biomedical Engineering and Chemistry is now progressing three research programs by developing aptamer. Aptamer is bio chip which is made with tens of millions living materials on glass slide. Like an antibody, it can sensor protein and it is used to exam toxic materials in human body. Developing aptamer is expected to be useful for diagnostic of diseases and environmental toxic materials. Prof. Kim said, "We are studying general system of aptamer and constructing basis of detecting system. In Hye-hwa Hall, the clean room where we can make nano-scale chips is well established. If aptamer technology will be industrialized, there will be many good effects." 'With Samsung electronics' supporting, aptamer medicine was developed. But it is not in the industrial area yet. In order to achieve the goal, she will continuously work with her project groups.

   However, the weak points also exist in the program. She said, "Even if we are given much financial support from outside, we are still under the difficulties of financial problems to study our project, because there does not exist any scholarship for undergraduate students. Therefore, our study ability is naturally weak." The field of biochip is not developed yet, so it is called "Blue Ocean in Biomedical Engineering." It is expected that DU's technology opens the door of industrializing nano-bio diagnostic field.




Students Group Studies

   There are several small clubs at DU. Students have group discussion, study their own field, and promote friendship among the members.


Computer Aided Progressive Study (CAPS)

   First, Computer Aided Progressive Study (CAPS) was established as an IT department club in 1988. CAPS has lively studied about computer. Do Hye-mi, a representative said, "We give our members opportunities to experience the change of informational commercial and to exchange people's information." CAPS also holds software exhibition annually and more than 15 seminars to exchange their information. But the problem is that they do not have good places to open seminars and exhibition. She also said, "We want to open our exhibition place in Wonheung Hall, Main Library, and Cultural Hall." CAPS now plans to make an academic ceremony about computer this year.

   Second, HAM is an academic group of wireless communication. Like in army, group members communicate with other university students by wireless communicator. Koo Seon-a, the head of HAM said, "We can develop understanding about mechanism getting intimate with other university students." HAM holds opening ceremony on first Saturday in July every year. In order to communicate with others, antenna is necessarily needed. So, since there is an antenna in Wonheung Hall, DU distributes HAM's room not to Student Hall but to Wonheung Hall. However, DU does not anymore support the club. HAM wants many students to get interested in wireless communication. HAM's activities could be brisker with more financial supports.

   Third, in Plant Biotechnology Department, there is a academic club, Pulip Arum. The members of Pulip Arum discuss scientific issues and study major subjects. Choi Jae-won, a head of the group, said, "More than twice a semester, we visit "DU Genetic Resources Center" and take care of plants and animals. And we make an exchange with alumni." Through the meetings with the alumni, they can have a opportunity to participate in research societies.

   However, Pulip Arum also undergoes shortage of supporting from the school authorities. "We are lacking of student lounge. Sometimes our club room is used to have seminar." There are many difficulties for keeping up the group, but they expect to do many activities for developing their club this year.





   In Capstone Design Fair 2008, Lee Jung-bok who won the first prize of the fair is now working at Samsung Electronics. He said, "When I was a junior, I worked at Samsung as an intern. My co-worker Cho Seung-pyo also works at software membership center in Samsung. The helpful thing to enter Samsung is ABEEK program." ABEEK stands for the Accreditation Board for Engineering Education of Korea. After strict evaluation about student's engineering education level, ABEEK gives students the accreditation. The program is to establish the basis of engineering education and ultimately to strengthen Korea? industrial competitive power. He also said, "Like ABEEK, if DU has more programs accredited, they should be very useful to get a good job." DU Educational-Industrial Center supports research activities. The Center receives the order of research subjects and organizes research expenses in order to perform effectively. However, to overcome the prejudice of the department of science and engineering, more interest and supporting is needed. Professor Kang Tae-won said, "DU should support actively the department which can make visible results."
