If you go to a laboratory in the Department of Agriculture and Life Sciences, you can see a sign stating, ‘High voltage current flowing. Don’t touch door.’ It sounds like as soon as you touch the door, you will receive an electric shock. A reagent bottle seems to say, ‘Eat and die’. Caution signs on a construction crane warn, ‘Watch your head’. Non-smoking signs caution that if you smoke, you will die. All of them are warning messages on the laboratories where dangerous research is carried out. Have you ever wondered about these laboratories or signs? What happens in these places? Are these nuclear weapons or chemical and biological weapons? They cannot be! I stand in front of the laboratory with bated breath. Prohibited areas… are you ready to travel to these places? If so, let’s open the door. Even I don’t know what awaits us.

○ The new technology on Liquid Crystal Display

The first lab to visit is the LCD laboratory in the 9th building of the College of Engineering. All have heard about LCD, even if they are not good at handling machines. A wide viewing angle is a major issue for liquid crystal displays (LCDs) in the flat display market. Recently you may be surprised by new machines, thinking, “Wow! It’s very thin!” The rapidly developing science technology makes thinner and bigger LCD monitors. The aim of past research was only to make large, thin and clear monitors. However, now LCD technology development enables something more: the ability of LCD monitors to protect the right to privacy. In other words, new technology means that only you can see the monitor but other persons cannot see. Portable machines make it hard to protect the right to privacy. The technology for switching the viewing angle of the LCD makes up for these weak points. Several studies on LCDs are carried out here, in the so-called ‘LCD room’. The LCD research in this lab works with companies and businesses closely. Also, it launches manufactured goods with its research results.

○ Reader of U-health Care
Have you ever heard of U-health care? U-health care is a service to monitor people’s health and to receive information through small and portable bio-signal sensors. Thanks to the emergence of broadband infrastructure and the development of wireless communication devices, things which were possible in the movies happen in reality. It is expected that the market for U-health care will grow rapidly in the future. This skill can maintain users’ best health conditions by managing them in the most appropriate time and taking the appropriate action even when they are in an unconscious state. This technology is also developed actively in the CBNU laboratory. In the 7th building of the College of Engineering, room 303, research is in full swing. In this room, the researchers extract minute biological signals of the heart and pulse by filtering and amplifying. Using these signals, the U-health care system will be able to make diagnoses and treat with possible medical devices. The most exciting research project associated with U-health care is a versatile self- biometric instrument. This device measures body movements, blood pressure and respiratory status and saves the data on a PC with Bluetooth in real-time. In addition, it is also portable. Another recently developed product is an anti-snoring pillow. The principle of the anti-snoring pillow is to use vibration to deter snoring.
