    Last year, an undergraduate student at KAIST donated his earnings from his developed app to the school. This time, the graduated students donated their earnings from the app they sold. Last December, the School of Computing student, Young-Hoon Park (25 years old), donated 10 million KRW ($8,200 USD). On September 9th, 2014, Park sold his smartphone application “Seoul Bus” to Kakao Corp. and donated the part of the earnings as a grateful to the school. In addition, Dong-Woo Kim (29 years old) who graduated from the school also donated 10 million KRW to KAIST with a message to use it for his younger students on last December. They are all graduated from the School of Computing at KAIST and worked together for the social commerce company, ‘Rottyful.’ The younger students’ donation news lead to the seniors’ donation; they founded a startup company, ‘Rottyful,’ together. The 8 co-founders of ‘Rottyful’—Kyung Ryul Goo (33), Dong Ju Kim (34), Dong Hee Yoon (34), Joon Ki Lee (34), Cham Sol Lee (33), Hyun Jong Lee (34), Sung Hoon Jang (33), and Joo Young Jung (34)—donated 100 million KRW ($82,000 USD) total, on last December. ‘Rottyful’ is a social commerce company provides a discount sale information based on the location information. This is the first service provides a real-time nearby discount information from the user’s location information. The service has spotlighted for the investigation of SoftBank Ventures Korea Corp, and has merged to Kakao Corp. in 2011. The alumnus, Sung Hoon Jang said, “I heard the news that my younger students have donated to the school,” and said, “We used to talk about the donation before, but we couldn’t take it to action. We were very proud of them when we heard the news, so we decided to donate as well.” The alumnus, Cham Sol Lee said, “We decided to donate together without any hesitation because we all were interested in the donation before,” and said, “We get a benefit from the school even after the graduation. I hope this donation to be helpful to the school.” After Kakao Corp. merged Rottyful, the startup members of Rottyful have lead Kakao’s growth. Now, most members have retired from the company and preparing for the next startup. The alumnus, Hyun Jong Lee said with smile, “I hope our donation lead to the other student’s donation,” and said, “We are planning on another startup, so we will work hard to donate more.” President Sung-Mo Kang at KAIST said, “The graduated students’ interest and investment is the motivation of KAIST’s growth,” and said, “I greatly appreciate for the alumni to support and encourage our school.” The appreciation plaque to the Rottyful startup members will be held at 1:00 PM, on Monday, February 1st.

    On December 20th, Jung Hee Kim, the Chief Executive Officer of ePapyrus Inc, has donated a software application which values about 21 million KRW (about 17,500 in USD). ePapyrus Inc. is a company established by Jung Hee Kim who graduated in the Computer Science at KAIST, specialized in developing an eDocument software application. In 1995, during his study at KAIST, he founded a company with two of his friends, using his dormitory room as their office. As he focus more on working, he paid less attention to his study. Eventually, he was expelled from the school on the first semester of his junior year for receiving academic warning a number of times, but he got a second chance to finish his school in 2003 and he successfully graduated from the school. Kim said, “I always wanted to give in return to the school for giving me a second chance to finish my school,” and said, “I found out that KAIST needed my company’s product, so I decided to donate the software. I am glad with it.” President Sung-Mo Kang at KAIST said, “The software he donated will be useful to our school,” and said, “We appreciate for alumni’s expectations and encouragement, and we will do our best to be the world’s leading university.

  • Soya Park, an Undergraduate Student of KAIST Schoo..

    Soya Park, an Undergraduate Student of KAIST School of Computing, Has Won the First Prize on Undergraduate Research Participation Program (URP). Along with URP, a paper from the research has been accepted from 2015 IEEE International Conference on Big Data(acceptance rate: 18.5%), with the details as follows: Paper: Practical message-passing framework for large-scale combinatorial optimization º Research Title: Large-scale Parallel Combinatorial Optimization through Belief Propagation º Researchers: Soya Park (School of Computing), Inho Cho (Dept. of Electrical Engineering) º Advisory Professor: Dongsu Han (Dept. of Electrical Engineering), Jinwoo Shin (Dept. of Electrical Engineering) ºTeaching Assistant: Sejun Park (Dept. of Electrical Engineering) º Abstract (or Summary): Graphical Model (GM) has provided a popular framework for big data analytics because it often lends itself to distributed and parallel processing by utilizing graph-based ‘local’ structures. It models correlated random variables wherein particular, the max-product Belief Propagation (BP) is the most popular heuristic to compute the most-likely assignment in GMs. In the past years, it has been proven that BP can solve a few classes of combinatorial optimization problems under certain conditions. Motivated by this, we explore the prospect of using BP to solve generic combinatorial optimization problems. The challenge is that, in practice, BP may converge very slowly and even if it does converge, the BP decision often violates the constraints of the original problem. This research proposes a generic framework that enables us to apply BP-based algorithms to compute an approximate feasible solution for an arbitrary combinatorial optimization task. The main novel ingredients include (a) careful initialization of BP messages,(b) hybrid damping on BP updates, and (c) post-processing using BP beliefs. Utilizing the framework, we develop parallel algorithms for several large-scale combinatorial optimization problems including maximum weight matching, traveling sales-man, vertex cover and independent set. We demonstrate that our framework delivers high approximation ratio, speeds up the process by parallelization, and allows large-scale processing involving billions of variables. Congratulations on receiving the award.

  • Identifying Digital Image Forgery Becomes Easy

    The following news reports are about the national first image forensic tool developed in Professor Heung-Kyu Lee’s Laboratory, which is on a web service for testing at 'http://forensic.kaist.ac.kr'. Don’t Even Think About Faking a Picture with Photoshop! – Donga Science 2015-06-12 The Research Team of Professor Heung-Kyu Lee in KAIST Developed ‘Digital Image Forgery Identification Technology’ In 2008, Iran announced that they launched ‘Shahab-3,’ a medium-range ballistic missile, and gave away the picture of launching four missiles for the proof. However, after revealing the picture, there was a rumor that the picture is a fake. Iran government made no comment about the rumor. Recently, a national research team developed an image forgery detector and verified the image. As a result, the detector found out three suspicious areas on the image, including smoke trails from three missiles. The research team of the professor Heung-Kyu Lee in KAIST developed an image forgery detection tool and created a webpage (forensic.kaist.ac.kr) for testing the tool. For example, if a picture of banana has modified by coloring light green on the top of the banana to make it fresh, the tool notifies the user by highlighting the modified area. Another example is that rafting people on a river; the tool even finds out that the picture is fake, a combined picture of a river and a rafting people. Professor Lee’s Team observed the statistical changes on the picture’s small dots (pixels) when modifying pictures. Using those changes, they developed the technology to find out the image forgery, such as copy-and-paste or retouches. It only takes a few seconds to find out. The research team commented that it would be helpful on research ethics or medical problems by applying the technology to pictures on academic papers, or medical videos. Professor Lee said, “The research on an image forgery detection is important, but there is a lack of research on it,” and he added, “We are planning to research on verifying various images successfully from the testing period.” Daejeon = Reporter Seung Min Jeon of Donga Science, enhanced@donga.com "Identifying a Picture from Photoshop"… On a KAIST Research Team’s Website – Chosun Ilbo 2015-06-11 By Gun Hyung Park As many people generally use digital pictures, it gets easy to modify pictures using photo editors, such as Photoshop. Modifying pictures can be critical if the picture is used for an evidence on a criminal investigation. A national research team developed an image forgery detection tool and opened to the public. Heung-Kyu Lee, a professor of KAIST School of Computing, said, “We opened a web service detects an image forgery from a digital picture, which is not noticeable to the human eye.” Lee said, “An image forgery technology has been on a research worldwide for more than ten years, but there was an issue on accuracy,” and said, “This technology can identify the forgery with a success rate of 90~95%.” The service is available on the website (forensic.kaist.ac.kr) for anyone, for free. The research team of Professor Lee developed a software application by using three image analyzing techniques introduced in the world. The basic technology is ‘Digital Multimedia Pixel Analysis’ technique. When modifying a picture, the digital image’s small dots (pixel; a smallest element in an image) rapidly cut off or smash. If there is such area, then the image is a fake. The tool also uses the technique detects a pattern generated by Photoshop by analyzing ‘compression’ and ‘restore,’ called, ‘format-based detection’ technique, and a unique pattern generated from each camera, called, a ‘camera-based detection.’ Using this tool, the research team demonstrated the picture of launching ‘Shahab-3’, a medium-range ballistic missile announced by Iran government, is a forgery. At that time, Iran government modified a different picture and announced it to hide the failure to launch the missile. However, the tool detects the alteration successfully. Professor Lee said, “When a user uploads a picture, the tool analyzes and highlights the suspicious area of the image with three analysis techniques in about a minute,” and said, “We believe that we can increase the accuracy by opening this technique to the public.”

  • Computer Science Returns… The Average Entrance Sco..

    A rapidly increasing number of people prefer Computer Science and Engineering to medical school. More than a half of the students taking KAIST SW courses are not majoring in Computer Science and Engineering. Taewon Seo (Professor of Computer Science and Engineering in Korea University) are teaching his students how to handle computer hardware. By Kyung-hoon Shin (nicerpeter@hankyung.com) A Digital Logic Design course teaches how computer software operates a hardware device. On April 26th in Korea University, 11 students of total 92 students enrolled as an elective (non-major); they are majoring in Business Management, Statistics, and Korean Language & Literature. In-Sung Kim (23), majoring in Business Management, made a perfect score in this course. Kim said, “I took this course because I think it is important to have a deep understanding of computers to work in IT and software companies in the future.” Taeweon Suh, the professor of the Computer Science and Engineering who teaches this course said, “There were no students taking this course as an elective,” and “The number of students interested in computer software is increasing.” As more students are interested in computer software, the computer-related majors are also getting a favorite major for students. The minimum score to enter the computer-related majors for top universities has increased, and there was a “registration war” on computer courses as many students wanted to take the computer courses. Computer Science students in KAIST have doubled. Computer Science and Engineering in Korea University is one of the top schools to enter among the college of science in Korea. According to the analysis result from Jongro private institute, the rank of the Computer Science and Engineering in Korea University has risen five places from 11th place out of 22 schools in 2012 to 6th place today. In addition, the Computer Science in Yonsei University also has risen from 16th place to 6th out of 26 schools this year. The number of people who wants to enter software-related schools has also increased. The competition rate of the Computer Science and Engineering in Korea University has been increased from 3.1:1 to 5.4:1, and the Computer Science in Yonsei Universty has been increased from 2.7:1 to 3.7:1 for a year. Every year, KAIST admits students without assigning any major, and let them choose them a major on sophomore. From 2004 to 2010, the number of students who choose Computer Science (currently the School of Computing) was below 50, but 69 students applied Computer Science last year, and 76 students chosen Computer Science this year. In addition, as the number of students who withdraw their application for the Computer Science and Engineering of Seoul National University to apply for other majors, such as a medical school, has been decreased, and the acceptance rate of the application has increased from 70% to 93%. Professor Kunsoo Park, the head of the Computer Science and Engineering of Seoul National University, said, “There are also a number of students who have chosen the Computer Science and Engineering and withdrew the admission of the medical school.” The minimum score to enter the Computer Science has increased because people believe that majoring computer-related field have an advantage of getting a job as industries demands more software technicians. Last year, the employment rate of the people who graduated from the Computer Science of Yonsei University was 80.8%, which is higher than the total employment rate, 64.1%. Also, the employment rate of the people who graduated from the Computer Science and Engineering of Korea University was 80%, which is 10% points higher than the total employment rate, 69.3%. An increasing number of students who take computer classes as an elective As the number of people who want to learn programming increases, a number of people register the Computer Science classes, including the major courses. In 2012, the enrollment rate of the students who take computer programming courses as an elective was 9%, but in this semester, the rate has increased to 55%. More than a half of the students in Computer Science courses, such as “Data Structures,” in the first semester of this year in KAIST take the course as an elective. Profess Doo-Hwan Bae, the head of the School of Computing said, “Two classes for each course was enough for students before, but even four classes per course is not enough today.” In Korea University, after enforcing the rule that forbids to take “C Programming” as an elective, non-Computer Science students even made appointments with professors to make an exception for taking the Computer Science courses as electives. According to the school, there were various reasons for taking Computer Science courses as an elective; a student majoring in business management wanted to learn programming for startup in the future, and another student wanted to learn it would be beneficial to get a job. Therefore, the department of the Computer Science and Technology of Korea University decided to admit the half of the upcoming students from liberal arts division. One possible reason non-Computer Science students want to take Computer Science classes is that there are many ways to apply software technology, such programming, into various fields of study. Soo Yeon Lee (21 year-old, majoring in Statistics in Korea University) said, “I am taking Computer Science courses because I am interested in analyzing combined field of Statistics and Artificial Intelligence.” By Hyung Joo Oh / Tae Hoon Kim, ohj@hankyung.com

  • “Dementia Relief by Simply Pressing a Button after..

    This is the news article about Dr. Sung Hoon Kim (Advisor: Professor Dae Young Kim), the CIO of Ybrain Inc., invented the world’s first wearable medical device for dementia relief. Kiwon Lee, the CEO of Ybrain, Introduces a Medical Device for a Dementia Relief 2015-05-06 21:33:05 Healthcare Startup The world’s first wearable medical device for a dementia relief Electronic signals stimulate brain cells… Currently under a clinical trial to 200 patients “A necessary technology in the world”… persuaded a venture capital for an investment. Kiwon Lee, the CEO of Ybrain Inc, explains about features of the wearable medical device, “Yband.” (provided by Ybrain Inc.) “Is there any way to help other people based on what we have studied so far?” Three companions who have successfully finished their master’s and doctorate program from KAIST put their heads together. Each student majored in Materials Science and Engineering, Brain Engineering, and Comupter Science, and they decided to do, “a significant job which is necessary to many people but difficult to try.” Finally, they developed a wearable medical device for dementia relief called, “Yband.” After creating a prototype, they established a venture company, “Ybrain Inc.” Kiwon Lee (32-year old), the CEO of Ybrain Inc, said, “Yband is currently under a clinical trial to 200 patients in Samsung Medical Center,” and “we are planning to put our products in market in the first half of the next year.” Yband is the world’s first wearable medical device to relieve dementia. Dementia is caused by a brain cell death or a reduction of the brain cell activity. Yband helps patients by giving a weak electronic signals to make stronger connections between the cells. Yband looks similar to a headband, and the inner part is made of hydrogels to transmit electronic stimuli. The device is simple; all the patient needs to do is pressing a button and wearing it, 30 minutes every day. Lee said, “Our objective is to develop a device which is simple and easy-to-operate,” and “the device rings if the patient wears the device in a wrong way.” Ybrain Inc. has registered 15 patents and applied 31 patents. Despite we developed a technology and established a company, a clinical trial was a burden to us. The clinical trial is mandatory to use it in hospitals, but it is too expensive for us to afford it. Therefore, Lee persuaded venture capitals by saying, “it is a necessary technology in the world,” and he also said, “For now, we got investments of 4.2 billion KRW ($3.86 million USD) from Stonebridge Capital, DSC Investment, and others.” In addition, Ybrain Inc. recently received a fund of 0.9 billion KRW ($0.82 million USD) from MOTIE (the Ministry of Trade, Industry & Energy). There are many newborn IT companies but few healthcare companies because it takes a longer time to develop and requires much more financial capitals than IT companies. In addition, it is difficult to startup for telemedicine technology and mobile medical devices are prohibited. In the end, the other two colleagues who established the company together has left and went back to school to study. Lee said, “I am proud of us for creating a device to help patients in pain,” and “some employees were formal doctors and nurses.” He made no comment on about being merged from larger companies with saying, “for now, I want to focus on making Yband with relatively cheap price for many patients to use it.” Translated the news report from: Korea Economic Daily (hankyung.com)

    The proposal from Scalable Graphics/Geometric Algorithm Lab. (Professor Sungeui Yoon), with the name of, “(SW Star Lab) Nearest Query Software Development for Mass Image Search and Prototype Rendering,” has successfully accepted. The proposal is about developing and extending “Proximity Computing” technology into various practical fields and opening the related software applications into public. The project will be supported up to 8 years with a fund of 0.3 billion KRW ($0.27 million USD) per year. Also, they will cooperate with Professor Otfried Cheong’s team to develop a strong technology on theory. Please refer to the attached document for more information about SW Star Lab. Government Plans to Raise National SW Technology up to 80% of the United States 2015.04.12 / PM 02:13 To make a competitive global software company, government enhanced supporting research and development (R&D); government made an objective to improve the software technology of Korea from 73% up to 80% of the United States. In addition, government plans to increase the number of global open-source software applications from 2 to 5, and global professional software companies from 20 to 50. On May 12th, MSIP (the Ministry of Science, ICT and Future Planning) prepared for ‘K-ICT SW Global Leadership Strategy’ to create software-driven society and made sure to support for creating a global software company. The strategy is one of the ‘three-year plan on economy,’ to transform the SW R&D project into focusing on raising national software industry to lead the international software markets. ▲ MSIP’s K-ICT SW global leadership strategy K-ICT SW Global Leadership Strategy is classified into three areas: ▲ the main source area ▲ application development area ▲ SW R&D creation of outcome. In the main source area, they select eight main-source areas on software technology, and nominate some graduate school laboratories into ‘SW StarLab’ and support up to 8 years. The eight main-source areas are operating systems, machine learning, intelligent software, database management systems, and others. They designated 10 Star Labs in this year and planning to increase the number up to 25. In an application development area, they support SW R&D project through stages by changing the project into a free competition under the policy that the proposer and performer must be the same. SW R&D project has simplified the applying procedures to help creative and challengeable startups, who have won from contest or the creative economy town, to commercialize and launch new products quickly. They plan to shorten the processing period from 4.5 months ∼ a year to 2.5 months. For developing companies, government is planning to introduce the MOS (Market Oriented SW) project in this year, using the market-selecting and incubating capability of investment companies, including global venture capitals. The GCS (Global Creative SW) project, which is for globalizing companies, will change the process to support R&D and overseas expansions within one-stop. They will announce in April after changing the system from government-leading project to a free competition. To accelerate taking the outcome of the SW R&D project, they reorganize the overall system of the project, such as tasks, evaluations, and maintenance (including quality assurance). They also plan to avoid external performance indicators such as the number of patents and support qualitative indicators, such as the capability of software quality management, the practical use open source software. Also, they apply the open-evaluation to professionalize the evaluation and plan to support improving the capability of software quality management. Yanghee Choi, the Minister of Science, ICT and Future Planning said, “This strategy is for the globalization of the national software industries by transforming the SW R&D project from deployment-oriented project into the achievement-oriented project.

    A KAIST Student Invented a Low-Cost 3D Printer: “Terrific!” “I found out that there were so many inconvenient features on the previous 3D printers, so I decided to create a new one for people to use conveniently.” Seok-hyeon Seo (23-year old, Computer Science, KAIST), who is a college student and has succeeded on business by inventing the cheapest 3D printer, said, “A good product has to be easy to use for many people.” He also said, “If I improve the performance continuously, the product will not only cheap but also shows a good performance.” Last year, Mr. Seo, Sung-hyun Cho (22, Mechanical Engineering, KAIST), Jong-hoon Choi, Won-hee Kim (21, Mechanical Engnieering), and Dong-jin Kim (23, Oxford Univ.) has gained attention for inventing a 3D printer costs about 900,000 won, which is a quite cheap price. They received about 100 pre-orders for 3D printer before the release, and they founded a company called, ‘KAIDEA’. They entrusted the business management section to the professionals, so they are only focusing on the product development. As the order continues, KAIDEA is planning to increase the number of factories in Gumi, Gyeongsangbuk-do during the first half of this year, and they are planning to make inroads into a larger market abroad, which is the expected the scale of 13.5 billion won in 2018. Mr. Seo said, “We have decided to leave the management part to the professionals since the beginning of designing the product.” He also said, “Since all of my friends are pursuing their own study, I think we made a right choice for the management part.” The idea of developing a low-cost 3D print came from ‘KAIST idea factory’. The idea factory is an open studio at trial, supported by the Ministry of Trade, Industry, and Energy, to help college students to perform an experiment and create a prototype with their creative idea. He said, “The idea factory made possible to develop a 3D printer.” He also said, “Because there are a number of equipment tools with additional financial support for materials, everyone can invent with their own ideas.” As for his future plan, he said, “I want to enter the graduate school in KAIST to study more after graduating next year,” and he show his ambition by saying, “I want to study more to give technological benefits to many people.”
