From Sep. 14 to 15, the 17th KAIST – POSTECH Science War (KPSW) was held at POSTECH campus. Though it rained heavily throughout two days, the passion of players and supporters were intense enough for them to enjoy KPSW.Hacking, Football, Science Quiz, E-Sports took place on the first day. Hacking started 9 AM to 9 PM, for 12 hours. Two teams were assigned the same problems. The one who solved it first took one point at hacking. Both sides succeeded in solving all the nine problems, but KAIST got ahead of us by close score of 847 to 843. The Football match was proceeded on a wet field, so suppo

Microfluidics is a study of systems that can process small quantities of fluids by using micro-channels smaller than one millimeter in at least one dimension. It is viewed as an essential tool for life science research, or in a larger way, biotechnologies. However, it has been difficult to commercialize this technology; taking a great deal of time and effort due to its fine and sophisticated technologies. Professor Lee Hyo-min (CE), Choi Chang-hyung (CET, Daegu Haany University), and David Weitz (PHYS, Harvard University) have developed a microfluidic technology that can continuously produce w

This May, the Magnetic Force Microscopy (MFM) laboratory at POSTECH was selected as outstanding safety management. Under the supervision of Professor Kim Jee-hoon of the Physics department, the students feel safe doing researches in the MFM laboratory.Professor Kim confidently asserted that the lab safety is momentous because “people’s lives are the priority,” and elaborated that human lives are “priceless” and that once one gets hurt, there is no turning back.According to Prof. Kim the first step to safety is assessing any expected threats and eliminating them. For instance, gas cylinders are

“We found about 80,000 tons of buoyant plastic currently in the GPGP.” Micro plastics, tiny fragments of plastic smaller than 5mm in size, make up the majority of items in GPGP (Great Pacific Garbage Patch). This trash vortex is getting bigger, and is now estimated to be fifteen times the size of South Korea. On May 28, the EU decided to phase out a plan to ban the use of the 10 most widely used the disposable plastic products, including straws and coffee sticks, by 2021. Korea’s annual use of plastic for packaging per person is the second largest in the world. The number of vinyl used per per

POSTECH has announced the appointment of Prof. Song Ho-Keun of Social Science at Seoul National University (SNU) as the Dean of POSTECH’s Humanities and Social Science Department (HASS Dept.) and have bestowed upon him an endowed professorship.Prof. Song was appointed as SNU’s first endowed professor in the field of HASS due to his accomplished research achievements regarding polarization and social conflict intensification. Beginning from 1994 as a SNU Prof. of Social Science, he also contributed to the advancement of SNU as the Head of the Social Science Department. Due to his appraised pers

The joint research team of Professor Kwon Se-kyun (GIFT) and Professor Levente Vitos (Royal Institute of Technology, Stockholm) have succeeded in solving the simultaneous increase in strength and ductility in high-entropy alloy through the theory of metal plasticity. This can be applied directly to the study of various existing metal materials as well as the development of stronger and more flexible steel – ultra high strength steel that is three times stronger than aluminum. The team noted the phenomenon of twinning, and succeeded in unraveling the secrets of high-entropy alloy. The alloy is

Prof. Sung H. Han (IME), a world-renowned human engineering authority, has been selected as a scholar member of the International Ergonomics Association (IEA), and named an IEA Fellow. The selection is more meaningful considering throughout the 60 year history of IEA, only 120 people have been selected for the scholar membership. The IEA was formed in 1959 and is the world’s leading academic institution attended by scholars from 51 countries around the world. It gives out membership to those who have outstanding academic achievements in the field of ergonomics and who have made international c

Hydrogen has been utilized as clean energy source in numerous areas including hydrogen cars and nickel-hydride batteries. The steam-methane reforming reaction whereby methane from natural gas is used to produce hydrogen in thermal processes is responsible for as much as 90% of hydrogen production around the globe. However, such a reaction has a major drawback: heavy carbon dioxide emission. As a countermeasure, a two-step thermodynamic water dissociation was spotlighted only to be labeled inefficacy because of a high reaction temperature of 1400℃.Assistant professor Jin Hyun-gyu from ME along

High-tech devices that are used in smartphones and wearable devices have complex nanometer-sized patterns. Since the size of electronics shrinks as technology evolves, devices face a difficult challenge in becoming smaller but being able to carry on more advanced functions. Professor Kim Jin-kon (CE) and Kim Sang-hoon (CE, Ph.D. Integrated) research team and Dr. Lee Woo’s research team developed a hybrid mould chemically layered in the field of polydimethylsiloxane with porous alumina that can be applied to the roll-to-roll process. This development was published as a title page paper on the A

During the 2018 KAIST- POSTECH Science War (KPSW), POSTECH succeeds to defeat KAIST in basketball but fails to win the two games: baseball and soccer. Competitive Match Ending in Regretful LossAs the opening game of the KPSW, the soccer game was held. After a game that went into overtime, our university was defeated by a score of 1 to 2. Because of the downpour, the condition of the field and the overall situation was not good. It was KAIST that scored the first goal. About 10 minutes into the game, the ball passed through the goalkeeper after a free kick.About 5 minutes after that, a free kic

After replacement of old equipment, there looked more people in the gymnasium fitness room than before. There was a freshman in sweatsuit of POSTECH rowing team, Lee Do-hyun (Mueunjae 18).“Today was the first day for my class to go the gym for Physical Fitness class (GEDU151). You know, the main entrance is closed except for special events and we should use the side entrance. By the way, only I and my two friends went to the side door and I realized that many students seldom use the fitness room.”“When I decided to enter POSTECH, firstly I searched for the library and the gymnasium. I also fou

For all our lives, until the moment we die, we worry about something. It doesn’t matter what it’s about or how insignificant it is, we worry about it. If somebody says that he or she isn’t worried about anything, we can be pretty sure like 100% sure that person is lying. Worrying is an integral part of our lives, a companion that even if we want to, can’t part away with.Personally, for me, I categorize worry into two types. One, worries concerning things that haven’t taken place yet (type 1). Two, worries about things that already took place (type 2). Unlike Type 2, Type 1 can be useful, as wo

Everything started when I checked a handicapped toilet of the Muenjae Memorial Hall. I was shocked because there were a lot of cleaning tools in the toilet. However, there were even more surprising facts. First, there is no toilet for the handicapped women. Second, there is no wheelchair accessible elevator. It is difficult for disabled people to take classes and to live in POSTECH because of limited facilities. POSTECH must make an environment where disabled people can live without any inconvenience. This is the barrier-free campus.Besides the Muenjae Memorial Hall, many other buildings in PO

My name is KIMUSANG.Kimusang means the most common last name in Korea ‘Kim’ pronounced in Japanese.I am a 33-year-old TOEIC instructor. I began my career in 2009. The year 2018 is my 10th anniversary! :) I’ve been working hard as a TOEIC instructor for my students but there has been always something missing. Something that completes me. I wanted to find it for a long time.In 2015, my close friend came out to me as a lesbian and I was surprised that the “COMING-OUT” was just that easy. I was literally shocked. I had denied myself as a lesbian in my entire life. I thought accepting myself as I a

As economy developed and life standards improved for many, pleasure goods became prevalent. Tobacco, marijuana, alcohol, and even sugar are goods categorized as goods consumed as means of pleasure. However, many of such goods generate negative externalities as they cause poor health conditions and addiction. To prevent such outcomes and supply the state budget, a type of excise taxes called ‘sin tax’ was made and applied in several different countries.Sin Tax has its origin from French ‘Gabelle Tax’ or also known as Salt Tax. Gabelle was an excise tax on a particular good- salt. Starting from

People can easily see the benefits of drone usage from package delivery to firefighting. With such motivations, experts and even regular citizens have been updating drone’s hardware and software to enable drones to perform various tasks. However, little did they know about the dark side of the drone usage.On Nov. 14, 2017, the International Convention on Certain Conventional Weapons was held in Geneva of which more than 100 nations were part. The subject of the convention was the ban on killer robots. At the convention, a seven-minute film called “Slaughterbots,” created by computer scientists

Alternative military service to be available in Korea from 2020On July 28, Korea’s constitutional court ruled that the military service act article 5, which regulates the types of military service, is unconstitutional because it fails to offer alternative services. However, the court made sure that military service act article 88, which punishes any person who refuses to serve the military without justifiable grounds, is constitutional. The court demanded that article 5 should be revised until the end of 2019. Since South Korea has been technically in war with North Korea until now, the milita

지난 14일부터 이틀간, KAIST-POSTECH 학생대제전(이하 카포전)이 우리대학에서 열렸다. 올해로 17회를 맞는 이번 카포전은 우리대학의 패배(종합 스코어 200:500)로 끝나, 15회부터 이어졌던 연승은 막을 내리게 됐다. 이로써 카포전 누적 전적은 7:9(우리대학:KAIST)를 기록하며, 누적 전적 동점 달성 시도는 물거품으로 돌아갔다.본 대회 진행에 앞서 사이버 카포전이 10일부터 진행됐다. 인기 게임 △오버워치 △스타크래프트 △하스스톤 △히어로즈 오브 더 스톰 △카트라이더를 비롯한 기존 종목에 이벤트전으로 진행된 배틀그라운드까지 추가해 주 중임에도 불구하고 학생들의 뜨거운 관심을 한데 모았다. 13일에는 대강당에서 우리대학 응원단 치어로가 전야제를 장식하며 축제 분위기를 끌어올렸다.카포전 첫날에는 △축구 △과학퀴즈 △해킹 △E-Sports(리그오브레전드)가 진행됐다. 축구는 폭우 속에서 1:1의 팽팽한 접전을 이어가던 중 연장전 후반에 터진 KAIST의 결승골이 승부를 갈랐다. 과학퀴즈에서는 양 팀이 같은 점수를 획득했으나 지뢰를 더 많이 찾은 우리대학이 규칙에 따라 패배했다. 12시간 동안 역전에 역전을 거듭하던 해킹도 양 팀이 모두 9문제

교육부가 지난달 17일 기자회견을 열고 4년제 대학들에 2022년까지 정시 모집 비율을 30% 이상으로 조정하라고 권고했다. 그리고 이를 충족한 대학들만 고교교육 정상화 기여대학 재정지원사업(이하 재정지원사업)에 참여할 수 있도록 할 예정이라고 밝혔다. △산업대학 △전문대학 △원격대학 △학생부교과전형 비중 30% 이상 대학들은 권고 대상에서 제외됐다. 현재 정시 모집 비율이 30% 미만인 대학들은 전국 4년제 대학 198개 중 35개(17.7%)다. 그중에는 2010년부터 신입생들을 학생부종합전형으로 100% 모집하는 우리대학도 포함돼 있다. 교육부는 이들 대학 모두가 정시 모집 비율을 30%로 늘리면 정시 선발 인원이 약 5,000명 이상 늘어날 것으로 예상했다.하지만 우리대학 김도연 총장의 생각은 교육부와 달랐다. “우리대학은 그 특성상 정시 모집 비율을 늘리는 데 동의할 수 없다”라며, 교육부 개편안을 수용할 수 없다는 입장을 밝혔다. 비록 앞으로 재정지원사업의 혜택을 받지 못하게 되더라도 우리대학의 입시 방침을 그대로 유지하겠다는 것이다.이에 대해 손성익 입학팀장은 “우리대학 특성상 교육부의 정시 모집 비율 인상 권고는 받아들이기 어렵다”라고 말했다.

우리대학 김기문(화학) 교수가 세계 최초로 쿠커비투릴을 주제로 한 서적 ‘쿠커비투릴:화학, 초분자 화학 그리고 응용’을 발간해 세간의 이목을 끌었다. 쿠커비투릴은 내부가 텅 비어있는 호박 모양으로, 다양한 분자나 이온을 집어넣을 수 있다. 이로 인해, 최근에는 쿠커비투릴을 분자를 담는 ‘나노캡슐’이나 개별 분자에 자극을 주어 원하는 대로 조종하는 ‘분자 기계’로 사용하기 위한 연구가 진행되고 있다.김 교수는 초분자 화학의 세계적인 권위자로, 쿠커비투릴의 응용 연구를 이끌며 나노·바이오 기술 개발에 크게 기여했다. 김 교수는 한 인터뷰에서 “쿠커비투릴에 대한 최초의 전문 과학 단행본은 쿠커비투릴에 대한 전체적인 소개와 최근 연구 동향에 대한 정보를 한눈에 접할 수 있는 좋은 자료이다”라고 말했다.
