Workshop on Techniques in Prediction Analysis for the Industry
There has been growing interest in the value and the application of “big data” in recent years. To meet this interest, a workshop was held to discuss the possibility and the future of prediction analysis, which is the next big step in data mining after big data. On February 25 in COEX, Seoul, the Department of Knowledge Service Engineering at KAIST held the 4th knowledge service workshop on “Techniques in Prediction Analysis for the Industry.” Predication analysis is a technique that can predict the future based on the understanding of the past and the present through analyzing “big data.” If “big data” is fuel in figurative sense, the prediction analysis serves as the engine. The Department seeks to help those companies interested in data mining by introducing fundamentals and some application examples to the executives of companies who are interested in implementation of the technique. The lecture was delivered by six professors from the Department of Knowledge Service Engineering and the Department of Industrial and Systems Engineering at KAIST. Thomas Miller, the author of Modeling Techniques in Predictive Analytics, covered the contents of his book at the event. Professor Moon-Yong Yi, Chair of the Department of Knowledge Service Engineering, said, “This conference will be important to companies that are considering the implementation of the prediction analysis as well as to students who are interested in the field.”

Asia Pacific Biotech News' Special Coverage of Korean Biotechnology
The Asia Pacific Biotech News covered five major biotechnology research projects sponsored by the Korean government in the areas of biofuels, biomedicine, bio-nano healthcare, and biorefinery. The Asia Pacific Biotech News (APBN), a monthly magazine based in Singapore, which offers comprehensive reports on the fields of pharmaceuticals, healthcare, and biotechnology, recently published a special feature on Korea’s biotechnology research and development (R&D) programs. The magazine feature selected five research programs sponsored by the Korean government, which are either part of the Global Frontier or the Climate Change Technology Development Projects. The programs are: Systems Metabolic Engineering Research: Distinguished Professor Sang Yup Lee of the Chemical and Biomolecular Engineering Department at the Korea Advanced Institute of Science and Technology (KAIST) has been leading a research group to develop biorefining technology using renewable non-food biomass to produce chemicals, fuels, and materials that were largely drawn from fossil resources through petrochemical refinery processes. Applying a systems metabolic engineering approach, the group succeeded in modifying the metabolic pathways of microorganisms. As a result, they produced, for the first time in the world, engineered plastic raw materials and gasoline. The team also developed a technique to produce butanol and succinic acid with a higher titer and yield using metabolically engineered microorganisms. Next-generation Biomass Research: Under the leadership of Professor Yong- Keun Chang of the Chemical and Biomolecular Engineering Department at KAIST, the research project, which belongs to the Global Frontier Project, develops biofuels and bioproducts utilizing microalgae typically found in water and other marine systems. Convergence Research for Biomedicine: Professor Sung-Hoon Kim of Seoul National University leads this project that develops targeted new drugs based on convergence research strategies. Bionano Healthcare Chip Research: Director Bong-Hyun Chung of the Korea Research Institute of Bioscience and Biotechnology has integrated information and communications technology, nanotechnology, and biotechnology to develop a diagnostic kit that can screen toxic germs, virus, and toxic materials in a prompt and accurate manner. Biosynergy Research: Led by Professor Do-Hun Lee of the Bio and Brain Engineering Department at KAIST, this research project develops new treatments with a multi-target, multi-component approach in the context of systems biology through an analysis of synergistic reactions between multi-compounds in traditional East Asian medicine and human metabolites. In East Asian medicine, treatment and caring of the human body are considered analogous to the politics of governing a nation. Based on such system, the research focuses on designing a foundation for the integration of traditional medicine with modern drug discovery and development. Director Ilsub Baek at the Platform Technology Division of the Ministry of Science, ICT and Future Planning, Republic of Korea, who is responsible for the Global Frontier Program and the Technology to Solve Climate Change, said, “It is great to see that Asia Pacific Biotech News published an extensive coverage of Korea’s several key research programs on biotechnology as its first issue of this year. I am sure that these programs will lead to great outcomes to solve many worldwide pending issues including climate change and healthcare in the aging society.” Professor Sang Yup Lee, who served as an editor of the feature, said, “At the request of the magazine, we have already published lead articles on our biotechnology research three times in the past in 2002, 2006, and 2011. I am pleased to see continued coverage of Korean biotechnology by the magazine because it recognizes the excellence of our research. Biotechnology has emerged as one of the strong fields that addresses important global issues such as climate change and sustainability.”

A Firefighter Drone That Flies and Crawls Up Walls
KAIST researchers developed a wall-climbing scout drone to fight fires in high-rises, finding the source of the fires and locating people trapped inside. The 1974 American disaster film Towering Inferno depicted well the earnest struggles of firefighters engaged in ending a fire at a 138-story skyscraper. To this day, fires at high-rise buildings are considered one of the most dangerous disasters. Skyscraper fires are particularly difficult to contain because of their ability to spread rapidly in high-occupant density spaces and the challenge of fighting fires in the buildings’ complex vertical structure. Accessibility to skyscrapers at the time of the fire is limited, and it is hard to assess the initial situation. A research team at KAIST led by Professor Hyun Myung of the Civil and Environmental Engineering Department developed an unmanned aerial vehicle, named the Fireproof Aerial RObot System (FAROS), which detects fires in skyscrapers, searches the inside of the building, and transfers data in real time from fire scenes to the ground station. As an extended version of Climbing Aerial RObot System (CAROS) that was created in 2014 by the research team, the FAROS can also fly and climb walls. The FAROS, whose movements rely on a quadrotor system, can freely change its flight mode into a spider’s crawling on walls, and vice versa, facilitating unimpeded navigation in the labyrinth of narrow spaces filled with debris and rubble inside the blazing building. The drone “estimates” its pose by utilizing a 2-D laser scanner, an altimeter, and an Inertia Measurement Unit sensor to navigate autonomously. With the localization result and using a thermal-imaging camera to recognize objects or people inside a building, the FAROS can also detect and find the fire-ignition point by employing dedicated image-processing technology. The FAROS is fireproof and flame-retardant. The drone’s body is covered with aramid fibers to protect its electric and mechanical components from the direct effects of the flame. The aramid fiber skin also has a buffer of air underneath it, and a thermoelectric cooling system based on the Peltier effect to help maintain the air layer within a specific temperature range. The research team demonstrated the feasibility of the localization system and wall-climbing mechanism in a smoky indoor environment. The fireproof test showed that the drone could endure the heat of over 1,000° Celsius from butane gas and ethanol aerosol flames for over one minute. Professor Myung said, “As cities become more crowded with skyscrapers and super structures, fire incidents in these high-rise buildings are life-threatening massive disasters. The FAROS can be aptly deployed to the disaster site at an early stage of such incidents to minimize the damage and maximize the safety and efficiency of rescue mission.” The research team has recently started to enhance the performance of the fireproof design for the exteroceptive sensors including a 2-D laser scanner and a thermal-imaging camera because those sensors could be more exposed to fire than other inside sensors and electric components. This research was funded by the KAIST Initiative for Disaster Studies and the KAIST Institute.

It has an ability to climb walls in smoky, narrow spaces inside buildings.

A KAIST Student Donates USD 26,000 to His Alma Mater
A KAIST undergraduate student who developed and sold a smart phone application donated USD 26,000 to his alma mater. Seung-Kyu Oh of the School of Electrical Engineering gave his donation to President Steve Kang of KAIST on November 24, 2015. This is the largest amount donated by an enrolled undergraduate. In 2010, at a time when android smart phones were just being released, Mr. Oh decided to develop a subway app because existing subway apps were not user-friendly. Mr. Oh’s “Subway Navigation” app checks the current operation hours and gives users the shortest path when the user selects points of departure and arrival. The calculation for the shortest path involves factors such as which train comes first, where and to what train to transfer, the first and last trains of the day, transfer passageway usage time, etc. To make the app useful to the largest number of people, Mr. Oh distributed it on the open market. Currently, the app is ranked the second most downloaded subway app, and has even made considerable advertising profits, having accumulated more than 5,000,000 users. This year, Mr. Oh received an offer from Kakao, an Internet company based in Seoul, Korea, to take over the app and sold it to them. Mr. Oh said that making a donation KAIST was the first thing that came to his mind when he earned this profit. Mr. Oh, who graduated from the Korea Science Academy, a science magnet high school, said that he felt a sense of responsibility for receiving support from Korea since high school, and that he decided to donate to KAIST as a way of returning the support that he had received so far. He further said that “if an individual’s efforts and talents created some profit together with what he or she learned from school, then the school that supported the student in furthering his studies has also played a significant role,” and that “likewise, our stellar alumni can contribute more to our younger classmates’ growth and development.” Mr. Oh, who is at his last semester, plans to join Kakao and will take on a job managing his subway app. President Kang said he hopes that “all KAISTians will emulate Mr. Oh’s example to support the school” and that “the university will use the money to invest further in its future.”
