As I am writing on a stale day like today thinking this will probably be my last column, I could not help but be a little retrospective. Writing a column is particularly challenging and cautious, not because there is nothing to write about, but because the column should not be an ode to dejection, and because, I am "confined to the narrowness of my experience that I should not obtrude my affairs so much on the notice of the readers." So, whilst contemplating on an apt topic that ticked all the boxes, I came across an idea that would be relevant to everyone one way or another.I realize that the

Greetings, I am Gil-Ho Lee from the Department of Physics. Our Quantum Nano-electronics Lab is researching quantum nano-devices. I assume you have heard about quantum mechanics. Although quantum mechanics has been occasionally used as a synonym for an "unknown phenomenon" in science fiction movies, there have recently been more reports on "real quantum mechanics" in the media. It seems to be a time when quantum mechanics, which was traditionally an area of physics, is becoming more widely known since its breadth is widely expanding and connecting with the field of engineering. Our group makes

When I said that I will take a break during the 2022 Spring Semester, my friends asked, “What will you do during the six-month-long break?” Though I considered this break when I was a sophomore, I made the final decision rapidly because of my surgery in February. I planned to work in a company through an internship program, learn some techniques related to computer languages, as well as learn some VR technology along with my one-month rest after the surgery. Many people told me to take a rest since I was exhausted, having had a busy time with lots of work from several clubs, projects, and a lo

It had been five years since I had set foot on foreign soil. My high school life was full of dreams of freely traveling abroad and experiencing the various exotic cultures around the world. Yet, Covid-19 remained triumphant even after two years of pandemic madness. Hence, I was jubilant when travel regulations were slowly lifted, opening a slight window of opportunity for overseas travel. My original plan was to go to Osaka, Japan, where a friend of mine was living. However, the regulations imposed by the Japanese government banned free travel and only allowed package tours for large groups.On

Professor Chong Soo Lee in the Graduate School of Energy and Materials Technology (GIFT) recently published two ISO (International Organization for Standardization) standards for evaluating the hydrogen embrittlement resistance of high strength steels, which are essential for the wide application of hydrogen energy. Such achievement was possible through the collaboration with the Korea Testing Laboratory (KTL). In commemoration of the enactment of these standards, The Postech Times requested a contribution article about Prof. Lee’s research and teaching life.Brief information about Prof. Lee a

I think summer break is a time to do things that I have not done before and gain various experiences. I had a good opportunity this summer to meet friends from MIT, Berkeley, Georgia Tech, Seoul National University, and KAIST at the same time during my research experience. Meeting students from various universities around the world, I realized that what I was thinking was wrong, and I was able to broaden my horizons.Academic GrowthDuring this summer break, I studied machine learning. Although I am planning to go to the Department of Computer Science and Engineering, my knowledge of machine lea

A year ago, I wrote a column addressing my despair towards humanity’s collective climate action – or the lack thereof. The column was a reflection of my “feeling like I must do something” but “completely clueless as to what to do”. That cluelessness is perhaps mutual for all of us involved because, for a fact, no single person alone can solve this crisis. Therefore, we feel powerless as individuals and decide not to take any action at all, because blaming the collective inaction is easier than putting all the burden on yourself. However, last time, I convinced myself that individual-level acti

Editor’s note: The following is a fictional first person narrative of the oracle in the Greek tragedy, Oedipus Rex. Where I landed was called Delphi by the locals. The temple of Apollo was built on Mount Parnassus, with great limestone cliffs surrounding its three sides. A perfect natural citadel. One could see a beautiful green valley stretched out in front of the temple. If one were to walk up the road, they would see buildings filled with treasuries donated by the wealthiest and strongest in the Greek world, which pilgrims can’t help but look in awe. I had a distaste for primitive civilizat

The winter break in the third year of high school is a good time to invest in hobbies. I fell in love with skiing and visited the Yongpyong ski resort more than 30 times. Skiing is a winter sport activity in which you come down from the top of the mountain while enjoying the view of the mountain range and the open sky. Skiing is attractive in that one can run at a speed that is difficult to experience in daily life and you can directly control the speed and posture. Feeling the air while skiing down at 70km/h is like thin ice crashing on your face which is cool and refreshing.The 2021/2022 ski

I am a professor in the Department of Material Science and Engineering (MSE). It has been 10 years since I joined POSTECH in 2013.Our research team recently developed an ultra-thin wearable sensor patch that monitors various cardiovascular health conditions. Applying inkjet printing technology, we were able to reduce the cost and time of developing sensors. In-depth research on inked electronic materials and an elaborately optimized printing process allowed us to develop thin-film-transistor arrays near commercialization levels. Current wearable pulse wave sensors only measure signals at a sin

A few months ago, a senior from my class told me that MBTI (Myers Briggs type indicator) can be a good choice to lead the conversation when going for a dinner with seniors. MBTI is a statistics-based table that distinguishes characteristics into 16 categories. It could be a very nice ice-breaker in an awkward situation between people meeting for the first time. Likewise, many Koreans use MBTI to start a conversation or to make a consensus between people who have the same MBTI. This “MBTI Fever” has been the main social topic in Korea for several years, but there are certain drawbacks; some peo

It has already been more than two years since COVID-19 changed our lives. Following the implementation of several living with COVID-19 strategies, the Korean government lifted the outdoor mask mandate on May 2, at the time of writing this column. To me, it is one of the most symbolic measures to recover towards a normal life and move away from the pandemic. Following the Black Death, smallpox, and the 1918 flu pandemic, humanity is likely to fight off another battle against future pathogens. Like many infectious diseases in history, humanity will soon overcome COVID-19 and we will return to no

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

In 2016, I was a transferred freshman at my high school and my first friend said that he was gay during lunch. He told me that he was gay in such a casual manner that it took me by surprise. I was fourteen, naïve, and had never met a gay person who openly discussed their sexuality before. My first memory of encountering gay people was when I was in elementary school. I was walking in a park late in the evening with my parents, and a gay couple was kissing passionately on a bench. My mom, a very devout Christian, quickly took me by my hand and made me look away. She looked more disappointed tha

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

Once upon a time, there lived a colossal dragon. It demanded that ten thousand humans be sacrificed to it every day, or it would decimate the population. The people resisted at first, trying every possible way to vanquish the beast, but its scales were too tough to penetrate its fiery breath too strong to endure. Hence, they resorted to pleasing the dragon, feeding as many humans as it desired. Over the eons, the dragon and its voracious demands became part of humanity. The king ordered the people to construct infrastructure to carry the people being shipped to the dragon’s lair. There were cl

I am Lee Jeong-rak, a cofounder of RC423, a rocket research group, and Perigee Aerospace, a projectile start-up. I currently research aerospace optimization and production processes at the Extreme Mechanics Laboratory (XML). The beginning of Perigee was a joint club created by students who were interested in rockets at various universities in South Korea. At Perigee, we are currently building a “satellite taxi” service that launches small satellites into the fixed orbit quickly. Perigee was recently selected as a preliminary unicorn company.Immediately after entering university, I wanted to st
