Sound of sex could alert internet porn filter by New Scientist, May 20, 2011
Software that can detect obscene contents from the internet has been developed by a research team at KAIST. The research team used a signal-processing technique, Randon Transform, to create spectrograms of a variety of audio clips, which can screen any pornographic sounds from websites. This audio-based screening method solves technological limits presented by automatic image-analysis systems that have already been used to catch unwanted pornography. New Scientist posted an online article on this development of new technology. Please copy and paste the following link to read more about the article.

'WWW2014' to be held in Seoul
WWW2014 (World Wide Web 2014) will be held in Seoul.
KAIST, Agency for Technology and Standards, W3C (World Wide Web Consortium), and ETRI (Electronics and Telecommunications Research Institute) all worked in cooperation to have WWW2014 in Seoul. The announcement that WWW2014 will be held in Seoul was announced in the Closing Ceremony of WWW2011 India Conference. Seoul overtook Adelaide and Melbourne of Australia.
Hosting WWW2014 in Seoul will be a great opportunity to showcase Korea’s Web Technology and get a grasp on the current trend in the field of high tech web technology and services.
The WWW conferences are attended by over 1,000 experts all over the world and are the world’s largest international conference in the field of IT.
Efforts to host the conference in their own respective countries are made on a national scale. The WWW2011 was hosted in India with the President of India giving an opening ceremony speech and WWW2013 will be hosted in Brazil in part due to the President himself sending a letter to express their desire to host WWW conference.

New Diagnosis System for Cardiovascular Disease Developed
Professor Park Hyun Kyu of the department of Biological-Chemical Engineering developed a new diagnosis system for diagnosing cardiovascular diseases using E.coli to test the homocysteine concentration in the blood.
The research team used the genetic recombination process to produce two different biologically illuminant nutrition cultures and compared the growth rate of the homocysteine between the two cultures by comparing the degree of luminescence.
The technology can allow the simultaneous analysis of blood samples en masse and is also economical and thus is being regarded as a major step forward in the field of homocysteine concentration analysis which is a rapidly growing field.
The conventional method used high performance liquid chromatography which took a long time to complete and was costly to run.
The advantage of the newly developed system is that it gets rid of costly steps as it only needs to grow E.coli and measure the luminescence of the naturally occurring illuminant.
The research was published as the cover paper of the April edition of ‘Analytical Chemistry’.

Artificial Photosynthesis Technology Developed using Solar Cell Material
Humanity is facing global warming and the exhaustion of fossil fuel. In order to remedy these problems, efforts to produce fuel without the production of carbon dioxide using solar energy continues constantly.
KAIST’s Professor Park Chan Beom and Professor Ryu Jeong Ki’s research teams of the department of Material Science and Engineering has developed an artificial photosynthesis system that mimics the photosynthesis in nature using solar cell technology.
The development of the technology is sure to pave the way to ‘Eco-Friendly Green Biological Process’.
Photosynthesis is the process by which a biological entity produces chemical products like carbohydrates using physical and chemical reactions using solar energy as its energy source.
Professor Park’s team was able to develop the artificial photosynthesis technology with a biological catalyst as its basis.
The result of the experiment was published in ‘Advanced Materials’ magazine on the 26th of April edition and has been patented.

Oh Myung Chairman of the Board gives Special Lecture in the S+ Convergence AMP Program
Chairman Oh Myung (CEO of Woong Jin Energy Poly Silicon) gave a special lecture in the KAIST S+ Convergence AMP Program with the topic of ’Dream of a Korea 30 years into the future’.
Chairman Oh insisted to the program attendees that they do their best in developing Korea through development of new technology and IT and that he considers education and development of new technology as the reason for Korea’s rapid development.
The program invites a guest speaker every month, apart from the planed lectures. The guest speakers were the top of their respective fields. In addition, various activities like riding the OLEV or domestic workshops or educational trips abroad imparted the ability to take on a global perspective.

World?'s First Automated Maritime-Docking between Naval Vessels
KAIST demonstrated the technology that allows automated maritime docking between naval vessels on the 26th of April at Busan, Korea.
The docking technology is seen as one of the key components for the mobile harbor as it prevents collision between two naval vessels upon docking. It was recognized as an important technology worldwide, but its technological limitations made it hard to commercialize.
The demonstrated included approaching a barge next to a cargo vessel, performing automated docking, and maintaining the docking and solutions in the advent of an emergency.
The mobile harbor is, in essence, is a ‘moving port’ and the automated docking technology is imperative to commercialize the mobile harbor. In order for a large container ship to unload cargo, the mobile harbor needs to approach the container ship and dock onto the side of the ship.
The technology required to keep the two moving vessels docked, out at sea, in an efficient and safe manner, is daunting. The conventional method involved sailors tying the two vessels together with rope which made it time consuming and hard to react quickly in emergency situations.
The KAIST mobile harbor research team developed the docking technology with ‘Mirae Industrial Machine’ Maritime Corporation, and ‘Ocean Space’. The mobile harbor will allow two vessels to perform loading and unloading of cargo regardless of wind and current, using robotic arms, vacuum attachment pads, wench, and are a complex, integrated system.
KAIST is planning on having a demonstration that encompasses all the technology required for mobile harbor: from the docking technology to the stabilizing crane technology.
Advancements made by KAIST are expected to speed up the commercialization and the real life application of mobile harbor.

From Pencil Lead to Batteries: the Unlimited Transformation of Carbon
Those materials, like lead or diamond, made completely up of Carbon are being used in numerous ways as materials or parts. Especially with the discovery of carbon nanotubes, graphemes, and other carbon based materials in nanoscale, the carbon based materials are receiving a lot of interest in both fields of research and industry.
The carbon nanotubes and graphemes are considered as the ‘dream material’ and have a structure of a cross section of a bee hive. Such structure allows the material to have strength higher than that of a diamond and still be able to bend, be transparent and also conduct electricity. However the problem up till now was that these carbon structures appeared in layers and in bunches and were therefore hard to separate to individual layers or tubes.
Professor Kim Sang Wook’s research team developed the technology that can assemble the grapheme and carbon nanotubes in a three dimensional manner.
The team was able to assemble the grapheme ad carbon nanotubes in an entirely new three dimensional structure. In addition, the team was able to efficiently extract single layered grapheme from cheap pencil lead.
Professor Kim is scheduled to give a guest lecture in the “Materials Research Society” in San Francisco and the paper was published in ‘Advanced Functional Materials’ magazine as an ‘Invited Feature Article’.
