Please introduce yourselfHi. I am a graduate in the Department of Chemistry (CHEM) at POSTECH, class of 2021. I am currently majoring in organic chemistry at POSTECH CHEM Graduate school.What did you value the most during your time at POSTECH? I tried to spend every day diligently. I set goals like getting good grades, participating in different club activities, researching in laboratories and extracurricular activities, and spending time with people I love. I worked to achieve each goal on a daily basis.Please tell us briefly about your experience of taking classes at POSTECH.One thing that I

Controversy over delivery fees has become a hot topic as major delivery apps have suspended promotions. Coupang Eats (a popular delivery application) launched a food delivery service in May 2019 and brought in a “single-order-per-delivery” system. Previously, it was common for deliverers to handle three to four cases of orders at once. Single deliveries could solve the problem of delays and food cooling. It had a short delivery time because only one order was handled at a time.The condition of the single delivery was 15% of the fee and 6,000 KRW for delivery, but Coupang Eats offered a promoti

Microplastics (MPs) are everywhere: from the Arctic snow to the deepest oceans, they can also enter the human body via food, drink, and the atmosphere. According to the University of Newcastle, Australia, people intake 2,000 pieces of plastic every week, which is equal to the weight of a credit card. In March, MPs were even detected in human blood, causing more concern about the problem.MPs are any small pieces of plastic less than five millimeters in length. They are categorized into two types: primary and secondary. Primary MPs are plastic fragments that are already five millimeters in lengt

Semiconductor industries have risen steadily during the last two years, which will be recorded as the worst stagnation in various industries around the world due to COVID-19. Increasing demand for IT devices via the non-face-to-face contact spread, additional data center constructions due to the OTT market growth caused a continuous rise in demand for semiconductor components.In South Korea, Samsung Electronics (SEC) was expected to receive a blow to sales due to the recently occurred GOS (Game Optimizing Service) incident, but they covered the losses through semiconductor sales. SK Hynix had

A technology that allows organic photodiodes (OPDs) to detect objects in strong light by adding small molecules has been developed. OPDs are optical sensors that detect color and brightness by converting light energy into electrical energy. Originally, objects could not be easily detected when receiving strong light such as sunlight.A research team led by Professor Chung Dae-sung (CE) and Dr. Kang Min-kyun (CE) succeeded in enhancing the performance of OPDs by synthesizing molecular switches. These research results were published in Advanced Materials.Unlike inorganic semiconductors, organic s

Achieving My Unfinished DreamWhen I was young, my dream was to become a reporter. In elementary school, I worked for the Seoul Children’s Press Group for three years. I did several interviews and wrote many articles. I felt a lot of pride as a reporter when I saw my article on the front page of the newspaper, and I think my dream began from that experience.As I entered middle school, I became interested in science and engineering, so my childhood dream of being a reporter slowly faded away, but I still did not completely let it go.In high school, I wrote for my school’s English newspaper, but

I am an assistant professor in the Department of Environmental Science and Engineering (DESE) at POSTECH. I joined the department in January 2020, before the spread of the COVID-19 pandemic. Before I came to POSTECH, I was an assistant professor of the Department of Civil, Construction, and Environmental Engineering at the University of Alabama (2017-2019) and a postdoctoral research associate at Princeton University (2015-2017). I was conferred MA and Ph.D. degrees (2012 and 2015, respectively) from the Department of Civil and Environmental Engineering at Princeton University. The title of my

중국의 과학 기술 발전이 놀랍다. 최근 발표된 한 언론 보도에 의하면, 중국의 과학 기술은 생명과학, 의학을 제외하면 과학 기술의 전 분야에서 미국을 앞서고 있다. 양적인 차원에서는 이미 2016년을 기점으로 중국이 미국을 앞서고 있었는데 이제는 질적인 면에서조차 미국을 능가하고 있다는 것이다. 과학 논문의 우수성을 보여주는 피인용 최상위 1% 논문 수를 국가별로 비교한 결과, 물리학, 수학, 공학 및 컴퓨터과학 등 과학, 기술 대부분 영역에서 중국이 미국을 앞섰다고 보고했다. 이는 충분히 예견된 것이다. 2016년 7월 과학 저널 네이처가 세계적 수준의 자연과학 학술지 68개에 우수한 연구성과를 발표한 국가와 연구기관을 분석해 순위를 매겨 발표하는 ‘네이처 인덱스’에서 중국이 1~9위를 차지했다. 또한, 컴공, 전자 분야의 최고 저널 중 하나인 IEEE 계통의 논문의 70% 이상이 중국의 대학이나 기관에서 출판된 것이다.중국 과학 기술의 놀라운 발전 이면에는 시진핑 집권 후 그들이 추구해온 ‘과학 굴기’가 자리하고 있다. 즉, 과학 기술의 발전을 통해 중국을 일으켜 세우고 미중 다툼에서 패권을 잡겠다는 야망을 실현코자 ‘과학 굴기’라는 슬로건을 내세운 것이

성경에 바벨탑이 나온다. 원래 세상은 한 가지 말을 쓰고 있었는데, 하늘 높이 탑을 쌓는 인간의 욕심을 보고 신이 벌을 내렸다. 사람들이 쓰는 말이 서로 달라져서 알아듣지 못하고, 여기저기 흩어져 살게 해 더 이상 하늘에 이르지 못하게 했다. 우리 역시 한반도를 벗어나면 다른 언어를 써야 한다. 이를 이어주는 것이 통역과 번역이다. 지구상에 존재하는 수많은 언어를 다 익힐 수는 없기에 영어를 공통어로 택해 여러 언어를 쓰는 사람들이 서로 소통한다.뿐만 아니라 같은 언어를 사용하지만 소통이 잘되지 않는 바벨탑도 있다. 사회의 모든 구성원이 같은 생각을 가지고 있지는 않다. 서로 다름을 인정하고 이해하며 살아가야 하는데, 다르다는 것을 틀린 것으로 오해한다. 남의 말은 듣지 않고 본인의 주장만 앞세운다. 사람의 귀는 억지로 닫을 수 없지만 입은 본인의 의지로 다물 수 있다. 항상 귀를 열어 잘 듣고, 본인의 말은 아끼라는 자연의 뜻인 듯하다. 그런데 이를 거스르는 경우가 훨씬 많다. 그래서인지 서로 반목하고 거리를 두며 사회는 분절된다. 세대 간의 갈등뿐 아니라 젠더, 빈부, 지역 등 세상에 존재하는 바벨탑이 점점 늘고 있다.바벨탑은 학문에도 있다. 태초에 학문

Google’s Contact lens, which diagnosed diabetes by analyzing glucose in tears, had become a hot topic. However, clinical trials have been suspended because the correlation between blood and tear glucose has not been verified, due to the low sensitivity of the glucose sensor. However, a new smart contact lens that can accurately diagnose blood glucose in real-time has recently been developed.Professor Hahn Sei Kwang, Dr. Kim Su-Kyoung, and Lee Geon-Hui in the Department of Material Science and Engineering developed smart contact lenses for continuous glucose monitoring in collaboration with Pro

Chelsea FC is experiencing financial problems. In an interview about the lack of money for away games, Chelsea player Kai Havertz said “That is not a big deal. I think that a lot of harder moments are in the world right now and I will pay, it’s simple.” What could have made them fall?Chelsea’s former owner Roman Abramovich suffered financial sanctions and his corporate account was blocked to prevent these assets from being repatriated to Russia. The resulting freezing of assets is increasing in real-time and it is the largest asset freeze action in U.K. history. As a result, Roman gave up all

On April 11, the 20th presidential transition team said, “We will push for a plan to unify the legal and social age calculation method based on ‘international age’ in accordance with president-elect Yoon Seok-yeol’s pledge.”First, the team plans to establish the “international age” and marking regulations through the Civil Act and the General Act On Public Administration to ensure the use of “international age” in the civil and administrative fields. After that, they will promote revising laws that use the existing age calculation and using only “international age” in official documents. In ad

Hi, I am Lee Wongi, a junior at POSTECH. My original dream was to become a chemist. I enjoyed chemistry because I was fascinated with the fact that I could construct novel materials utilizing various materials as building blocks. So, I naturally spent a lot of time around chemistry until middle school.My first real experience with computers was in high school. Before, the only times I had interacted with a computer was when I hung out with my friends after exams and played a game or two. Since I also used a 2G phone at the time, Tetris and Sudoku on my phone were the extent of my exposure to d

Burnout syndrome refers to the symptom in which a person feels extreme physical and mental fatigue while taking on a certain job and loses the enthusiasm and sense of accomplishment that comes from the job. On May 25, 2019, the World Health Organization (WHO) classified burnout syndrome as a recognized medical problem related to work in the 11th International Classification of Diseases. This means that burnout syndrome can occur very frequently for modern people.Burnout syndrome mainly affects people who set high goals and sprint within a short period of time. In addition, social factors such

코로나19 일일 신규 확진자가 2월 초순에 오만 명을 넘고는 중순 들어서는 10만 명을 넘나드는 상황이 전개되고 있다. 2020년 1월 국내에 코로나19가 처음 등장해 소수 확진자의 동선이 전 국민의 주목을 받았던 때나 대구 신천지 교인의 집단감염 사태로 여론이 시끄러웠던 때와 비교하면, 최근의 감염 양상은 과거에 상상하지 못했던 규모로 전개되고 있어도 국민과 언론 모두 차분한 상태다. 이러한 안정 상태는 K-방역의 성공 경험과 오미크론 변이의 특성에 대한 정보의 확산 덕분이라 하겠다. 널리 알려진 대로 오미크론 변이의 감염력은 매우 높지만 치명률은 그렇지 않은 양상을 보인다. 따라서 백신을 맞았고 기저질환이 없는 사람이라면 기본적인 방역 규칙을 준수하는 한 따로 걱정할 일은 없다고 할 수 있다. 신규 확진자의 대부분을 재택 자가 관리로 돌림으로써 방역 당국 차원에서 사실상의 단계적 일상회복을 시행하는 것도 이러한 판단에 따른 일이다.요컨대 코로나19 사태가 변화하고 있는 것인데, 이와 관련해 우리대학의 교육 방침을 돌아볼 필요가 있다. 지난 2년간 우리대학은 학부 교육을 사실상 전면적인 비대면으로 시행해 왔으며 학교 교정은 코로나19 청정 지대에 가까운 놀
