▲ Seoul National University Architecture Researcher Ju Dong Lee

 

Seoul National University’s Architecture Researcher Ju Dong Lee (Advisor: Hyung Koo Kang) won the Best Paper Award at the International Conference on Engineering and Natural Science 2015 (ICENS 2015).

 

The conference was held in Bangkok, Thailand on January 21.  The conference is held annually and of 86 papers presented this year, Researcher Lee’s paper was chosen as the best.

 

Researcher Lee’s paper was called “Viable Options as Possible Concrete Floor Systems for Basement Parking Structures.”  In particular, this paper used half-freecast concrete and post-tensioning as a new method. 

 

The method was to support a strand that was already stressed by placing plastic over existing concrete and then adding additional concrete.  This method simplifies an existing method while at the same time strengthening the support. 

 

Researcher Lee stated, “By winning this award, I realized the need for a new method in the real world, and I will continue to conduct research into parking structures.”

Professor Jang’s research team asserted that they developed an artificial intelligence technology using cartoon big data.  Professor Jang’s research team announced on the 4th that they developed an imagination machine using the cartoon’s illustrations and language. 

 

They scanned 183 episodes of Pororo, or 1,232 minutes of the cartoon to the imagination machine.  Afterwards, they found that the machine formed brain neural networks that resembled associative memory structures.  Through testing, they found that through images they were able to come up with discussions and vice versa. 

 

This imagination machine can be used in a variety of industries.  For example, the machine can be used in the education industry to teach a foreign language.  By reading the student’s body language as well as verbal language, the machine can teach more effectively. 

 

By scanning different types of videos, the machine can learn information from different domains. 

 

Professor Jang stated, “Until now, there has been a lot of research into big data.  Technology that utilizes cartoon big data has not been seen before.  I believe that this is an arena that has great potential.” 

 

Professor Jang’s research team will attend the 29th Association for the Advancement of Artificial Intelligence (AAAI-2015) held in Austin, Texas on January 28 (Wed).   AAAI is the top artificial intelligence conference that only invites the top 12% in the field. 

 

Professor Jang graduated from SNU in 1986 with a bachelor’s in computer engineering before received a Ph.D. from Bonn University in Germany.  He has conducted research at Seoul National University since 1997.

Smart Artificial Skin

Professor Daehyung Kim from the Chemical and Biological Engineering department succeeded in placing small sensors inside soft silicone rubber to assess pressure, temperature, humidity, and even force. Professor Daehyung Kim’s research team developed a smart artificial skin by using polyimide (PI) walls and silicone nanoribbon (SiNR) sensors that can feel temperature, humidity, and pressure. Gold (Au) nanoribbons are also placed inside transparent silicone rubbers to achieve this effect. The internal sensors can figure out a foreign object’s temperature and humidity when it is touching the artificial skin. It can also find out the amount of pressure exerted on the skin and the artificial skin can also emit heat so that if an artificial skinned hand is holding a real hand, the owner of the real hand will be able to feel the heat. The research team was able to verify this by using heat-sensing cameras.
Because the research team developed the artificial skin to act like real human skin, the sensors will still act normally even when the skin is stretched 30% such as when a hand is in a fist or shaking someone else’s hand. The sensor and heat can function even when stretched to 50% and this includes areas like the wrist where flexibility is very important. In addition, the research team was able to send the signals sent from the artificial skin sensors to a mouse’s brain. After attached the artificial skin sensors to a live mouse, they found that the EEG revealed the mouse was able to feel whenever pressure was placed on the artificial skin. Therefore, this has the potential for the artificial skin to be used on artificial legs and hands for amputees to allow them to feel. Professor Kim stated, “We were successful in conducting an experiment with an artificial arm, and in the upcoming years the artificial skin can be used on artificial limbs so that touch may be possible.”
This research was published on the online version of “Nature Communications” on January 9, 2015. 


Creative Design Fair 2014

The Creative Design Fair was held between September 16 and 19, 2014. This was the third time the Creative Design Fair was held, through the School of Engineering's Education Innovation Center and other contributions. The examinations were held on the 16th on the 4th floor of the Academic and Cultural Center. On the 17th and 18th, an exhibition of the products were displayed in booths and stages at the main square. In detail, the program involved 35 teams from architecture, materials engineering, industrial engineering, and naval architecture and engineering to compete in 5 different areas. In particular, the contest showcased the products from Eyecong, Moonghwan, SNUSAT, NCSTEM, Emotimopter, and others. Executives from the Dongbu Group attended the award ceremony, as they are sponsors. The School of Engineering festival was held on the 18th at the same main square and involved a game competition and singing competition. On the last night, the 19th, there was a marketplace at the main square as well as basketball and soccer competitions in the gym and field. The winners of the soccer competition were the Computer Engineering, followed by Civil and Environmental Engineering and Mechanical and Aerospace Engineering. The basketball competition was won by Mechanical and Aerospace Engineering, followed by Industrial Engineering and Architecture. A rock festival was held at night in the main square. The winners of the 2014 Creative Design Fair received funding from the Dongbu Group and have been able to attend an overseas training program in Stanford in the United States and an electronics show in Japan this January. 


Increasingly Efficient Hybrid Energy Storage Device Material Developed

Professor Kisuk Kang from the SNU's department of Materials Engineering, POSTECH Professor Jinwoo Lee (Chemical Engineering), Researcher Eunho Im, JoongAng University Professor Sunghoon Yoon, and their research team developed a hybrid supercapacitor to improve the storage capacity and recharge speed as well as increase the lifetime of the device. A hybrid supercapacitor acts like a battery to store energy.
The research team used Niobium Oxide (Nb2O5), which is superior to titanium for coating the material in use in the hybrid supercapacitor. In approximately one minute, 60% of the total storage capacity can be charged. Compared to titanium, this is approximately 1.5 times faster. Additionally, after 1000 charges, the storage device still maintains 90% of the original capacity, which is again better than titanium-based batteries. Professor Jinwoo Lee will conduct additional research for use in hybrid electricity cars. This research has been published online in ACS NANO. 


Recognitions and Awards

Safe Waist Belt for Baby Carriages Wins Four International Awards

Juniors from the Mechanical and Aersopace Engineering Department Dongyeon Han, Soongsil University Computer Engineering Junior Dongeun Kim, and Dongduk Women's University Business Senior Jihye Lee developed "Carry Wear," a safety belt for baby carriages. It has won a total of 4 international awards: the Italy Invention Award at the Vietnam International Invention Fair, Thailand Invention Award, Qatar Energy AGRI GREEN Award, and Vietnam International Invention Award. The waist belt will prevent the baby carriage from rolling down a sidewalk and increase safety. One one end the product is attached to the baby carriage's handles and the other is attached to the waist. This means that the carriage can be pushed without the hands and solely from the waist energy. The carriage can be pushed around even while using a smart phone or holding a grocery bag. Heavy carriages made for twins can be more easily pushed with the additional power from the waist. There is an LED light attached to the belt so that people will be able to see the carriage at night. Han stated, "You do not need to buy a whole new carriage; you just need the carry wear to improve safety, so this is a great product for moms."

Writer: admin


▲ Seoul National University Mechanical and Aerospace Engineering Professor Man Soo Choi


A domestic research group stated that they used nano crack to measure displacement, vibration, pressure, and sound more than 100-1000 times better than current sensors.

 

This research was conducted with a grant from the Ministry of Science, ICT, and Future Planning through their Global Frontier Project’s Multiscale Energy System Research Team (Team Leader Man Soo Choi).  It was a joint research with Professor Man Soo Choi (Seoul National University) and Professor Tae IL Kim (Sungkyunkwan University).  The research was published in Nature on December 11 (Thursday).  (Title: Ultrasensitive mechanical crack-based sensor inspired by the spider sensory system)

 

A spider has great sensory abilities due to its ability to assess the small vibrations.  This is because spiders have a crack near their ankle that allow them to feel these small vibrations.
 
The research team realized that spiders had nanocracks in the areas where they felt the small vibrations, and used this as a model to develop their sensitive sensors.  It is predicted that they will develop even better sensors by utilizing their findings in various fields.
 
A spider’s sensory organs have a soft inside with a hard outer shell, through which the nerve cells are connected.  When there is a vibration in the outside, the spider’s cracks become larger or smaller to reflect it to the nerves.  The research team analyzed how these movements work to come up with the nano crack. 
 
The currents that flow around the crack can be very small when the crack is completely closed, but they can be great when the crack is open.  This change can be measured to figure out how different vibration strengths are felt.
 
The research team used this to come up with a sensor that is 100-1000 times more sensitive than current sensors.

 

Team leader Man Soo Choi stated, “This research can be used to measure the change in the body’s physiological sense and can be used in a variety of ways.  This is a continuation of former Professor Gap Yang Seo (Seoul National University), who unfortunately passed in an accident last June. We dedicate this paper to Professor Gap Yang Seo.”

The Golden Time of Super Bacteria Treatment ... 2015-01-14
Writer: admin

▲ Seoul National University Electrical and Information Engineering Professor Sung Hoon Kwon


Seoul National University School of Engineering announced on the 18th that Professor Sung Hoon Kwon’s research team from Electrical and Information Engineering worked with Seoul National University Hospital Laboratory Medicine, Biomedical Engineering, and new venture company QuantaMatrix to come up with the fastest super bacteria testing technology in the world.

 

 The super bacteria are resistant to antibiotics.  Until now, it took a whole day to figure out if super bacteria are resistant to antibiotics.  However, the joint research through Seoul National University and QuantaMatrix developed a new technology that will allow for the testing to complete in 3-4 hours.

 

The current method is to assess whether the antibiotics react to the bacteria under a microscope.  Bacteria and agarose-mixed solution are injected in microfluidic biochip and are given antibiotics to fixed bacteria to see how the cells react.

 

 The research team used this method on 189 clinic strains at Seoul National University Hospital and Incheon St. Mary’s Hospital.  This method that only takes 3-4 hours satisfied the U.S. FTA standards.

 

Professor Sung Hoon Kwon from Seoul National University stated, “If we use this method, we can quickly assess if patients can be treated with antibiotics for their bacteria. This can reduce the amount of time spent in hospitals.”
 
This method can be used not only on super bacteria, but for new antibiotic development screening.  It can also be used in antibiotic drug development, which has stagnated.  This research was published in the Science Translational Medicine Journal on December 17.

▲ Microfluidic biochip utilized cell observation method
At one time, 20 different antibiotics can be tested on microfluidic well plated chips. Agarose mixed solution are mixed with the bacteria then placed on the chip. After it solidifies, the antibiotics are given.  The bacteria trapped in the agarose can be viewed through a microscope.
