Explanation for the polymerized nucleic acid enzyme's abnormal activation found
KAIST’s Professor Park Hyun Kyu of the Department of Bio Chemical Engineering revealed on the 23rd of December 2010 that his team had successfully developed the technology that uses the metal ions to control the abnormal activation of nucleic acids’ enzymes and using this, created a logic gate, which is a core technology in the field of future bio electrons.
The polymerized nucleic acid enzyme works to increase the synthesis of DNA and kicks into action only when the target DNA and primers form complimentary pairs (A and T, C and G).
Professor Park broke the common conception and found that it is possible for none complimentary pairs like T-T and C-C to initiate the activation of the enzyme and thus increase the nucleic acid production, given that there are certain metal ions present.
What Professor Park realized is that the enzymes mistake the uncomplimentary T-T and C-C pairs (with stabilized structures due to the bonding with mercury and silver ions) as being complimentary base pairs. Professor Park described this phenomenon as the “illusionary polymerase activity.”
The research team developed a logic gate based on the “illusionary polymerase activity’ phenomenon.” The logic gate paves the way to the development of future bio electron needed for bio computers and high performance memories.
Professor Park commented, “The research is an advancement of the previous research carried on about metal ions and nucleic acid synthesis. Our research is the first attempt at merging the concepts of the two previously separately carried out researches and can be adapted for testing presence of metal ions and development of a new single nucleotide polymorphic gene analysis technology.”
Professor Park added that, “Our research is a great stride in the field of nano scale electron element research as the results made possible the formation of accurate logic gates through relatively cost efficient and simple system designs.”
On a side note, the research was funded by Korea Research Foundation (Chairman: Park Chan Mo) and was selected as the cover paper for the December issue of ‘Angewandte Chemie International Edition’.

Rise of the mimic-bots that act like we do: Human-machine teamwork.
An online magazine, Technology Marketing Corporation, based in the UK published an article, dated January 8, 2011, on a robot research project led by Professor Jong-Hwan Kim from the Electrical Engineering Department. The article follows below:

Rise of the mimic-bots that act like we do Human-machine teamwork
(New Scientist Via Acquire Media NewsEdge) Rise of the mimic-bots that act like we doA robot inspired by human mirror neurons can interpret human gestures to learn how it should actNow follow meA robot inspired by human mirror neurons can interpret human gestures to learn how it should actA HUMAN and a robot face each other across the room. The human picks up a ball, tosses it towards the robot, and then pushes a toy car in the same direction.
Confused by two objects coming towards it at the same time, the robot flashes a question mark on a screen. Without speaking, the human makes a throwing gesture. The robot turns its attention to the ball and decides to throw it back.
In this case the robot"s actions were represented by software commands, but it will be only a small step to adapt the system to enable a real robot to infer a human"s wishes from their gestures.
Developed by Ji-Hyeong Han and Jong-Hwan Kim at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, the system is designed to respond to the actions of the person confronting it in the same way that our own brains do. The human brain contains specialised cells, called mirror neurons, that appear to fire in the same way when we watch an action being performed by others as they do when we perform the action ourselves. It is thought that this helps us to recognise or predict their intentions.
To perform the same feat, the robot observes what the person is doing, breaks the action down into a simple verbal description, and stores it in its memory. It compares the action it observes with a database of its own actions, and generates a simulation based on the closest match.
The robot also builds up a set of intentions or goals associated with an action. For example, a throwing gesture indicates that the human wants the robot to throw something back. The robot then connects the action "throw" with the object "ball" and adds this to its store of knowledge.
When the memory bank contains two possible intentions that fit the available information, the robot considers them both and determines which results in the most positive feedback from the human?- a smile or a nod, for example. If the robot is confused by conflicting information, it can request another gesture from the human. It also remembers details of each interaction, allowing it to respond more quickly when it finds itself in a situation it has encountered before.
The system should allow robots to interact more effectively with humans, using the same visual cues we use. "Of course, robots can recognise human intentions by understanding speech, but humans would have to make constant, explicit commands to the robot," says Han. "That would be pretty uncomfortable."Socially intelligent robots that can communicate with us through gesture and expression will need to develop a mental model of the person they are dealing with in order to understand their needs, says Chris Melhuish, director of the Bristol Robotics Laboratory in the UK. Using mirror neurons and humans" unique mimicking ability as an inspiration for building such robots could be quite interesting, he says.
Han now plans to test the system on a robot equipped with visual and other sensors to detect people"s gestures. He presented his work at the Robio conference in Tianjin, China, in December. nAs the population of many countries ages, elderly people may share more of their workload with robotic helpers or colleagues. In an effort to make such interactions as easy as possible, Chris Melhuish and colleagues at the Bristol Robotics Laboratory in the UK are leading a Europe-wide collaboration called Cooperative Human Robotic Interaction Systems that is equipping robots with software that recognises an object they are picking up before they hand it to a person. They also have eye-tracking technology that they use to monitor what humans are paying attention to. The goal is to develop robots that can learn to safely perform shared tasks with people, such as stirring a cake mixture as a human adds milk.

KAIST developed a plastic film board less sensitive to heat.
The research result was made the cover of magazine, Advanced Materials and is accredited to paving the way to commercialize flexible display screens and solar power cells.
Transparent plastic and glass cloths, which have a limited thermal expansion needed for the production of flexible display screens and solar power cells, were developed by Korean researchers.
The research, led by KAIST’s Professor Byoung-Soo Bae, was funded by the Engineering Research Center under the initiative of the Ministry of Education, Science and Technology and the National Research Foundation. The research result was printed as the cover paper of ‘Advanced Materials’ which is the leading magazine in the field of materials science.
Professor Bae’s team developed a hybrid material with the same properties as fiber glass. With the material, they created a transparent, plastic film sheet resistant to heat. Transparent plastic film sheets were used by researchers all over the world to develop devices such as flexible displays or solar power cells that can be fit into various living spaces. However, plastic films are heat sensitive and tend to expand as temperature increases, thereby making it difficult to produce displays or solar power cells.
The new transparent, plastic film screen shows that heat expansion index (13ppm/oC) similar to that of glass fiber (9ppm/oC) due to the presence of glass fibers; its heat resistance allows to be used for displays and solar power cells over 250oC.
Professor Bae’s team succeeded in producing a flexible thin plastic film available for use in LCD or AMOLED screens and thin solar power cells.
Professor Bae commented, “Not only the newly developed plastic film has superior qualities, compared to the old models, but also it is cheap to produce, potentially bringing forward the day when flexible displays and solar panels become commonplace. With the cooperation of various industries, research institutes and universities, we will strive to improve the existing design and develop it further.”
