My travels usually revolve around delicacies; pizza, risotto, croissants - mainly because the trips were planned by my parents. This focus often obscured historical wonders that surrounded me, making them look like mere chunks of stone. This is something I regret, but the summer of 2016 was one exception. This trip to Barcelona, Spain was one that greatly influenced me, and one of my favorites so far. This is where I first met Gaudí. From the moment we entered the heart of the city, “vibrant” was the word that first came into mind. Bright colors and lively people greeted me as we made our way

The Arctic sea ice plays a critical role in regulating global warming by reducing the rate of Arctic warming by reflecting incoming solar radiation and also insulating the atmosphere from the warmer water below. Without this protective sea ice buffer, Arctic warming will intensify quickly, accelerating global warming. Thus, we can regard the Arctic sea ice as the immune system of the human body, which protects us from harmful things. Due to the increased greenhouse warming by human activities, Arctic sea ice has been rapidly melting during the past decades and the ice-free Arctic condition was

“You should have various experiences in your campus life.” That was the advice given to me as I was about to enter POSTECH. I completely agree with the tip, and it seemed I was confident enough to accept it. Looking back, that period was marked by significant interest in the question, “Where can artificial intelligence be applied?” Given that artificial intelligence (AI) has been creating wonders by assembling theories of AI, high-quality data that could be material for everything, and computing resources, I am hopeful about creating an AI model that defines the correlations between different

In the vast realm of consumerism, advertising serves as a multifaceted tool that transcends mere information dissemination. Beyond promoting products and services, advertisements wield the power to tap into the intricate web of human emotions, steering them toward tangible actions. The overarching objective remains constant - to resonate with consumers, elicit emotional responses, and ultimately drive sales. This dynamic interplay between emotion and action unfolds through the strategic use of language, visual elements, and psychological techniques carefully embedded within advertisements. At

Introducing my research I study about complex systems, not meaning that they are merely complicated. The complex system consists of a multitude of elements. They make interactions among themselves. It results in, throughout the system, the properties which could not be seen in discrete components. That is, we should not think of them as separate ones, and we can say that one plus one is no longer two. Looking at the system in this perspective, the unfound and hidden pattern and order can finally be discovered. The 2021 Nobel Prize in Physics was conferred to researchers who contributed to the

I have had the privilege of socializing with individuals from various countries, living in Europe during my youth, fostering friendships with POSTECH exchange students since first grade, and now being able to deepen these connections by working as a PBUD this semester. A recurring observation in my interactions with foreign friends is their remarkable closeness, irrespective of age, arising from cultures that lack the rigid hierarchical norms in Korea. This characteristic, reflective of a culture that dismisses hierarchy, enables easy communication during initial encounters. This cultural trai

In recent times, Ha-Seong Kim, a Korean player in the Major Leagues, made headlines for being nominated for a Gold Glove Award this year in the utility position. The Gold Glove Award is an award that honors the best defenders at each position in the National League and the American League and is voted by coaches and managers of Major League Baseball (MLB). It is not every day that we see Korean players recognized for their abilities, especially in sports that require innate physical talent. Often, these sports are usually dominated by Western players. But when I think about it, I can see that

Introduction to Medical Imaging AI Medical imaging encompasses various imaging modalities such as X-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and positron emission tomography (PET). They behave as a window to investigate various characteristics of the human body. These imaging techniques enable clinical experts to observe internal organs, tissues, and physiological processes, aiding in the detection and diagnosis of diseases and injuries and further intervene to cure and prevent the disease. My research includes but is not limited to, developing Artificial In

Nowadays, a lot of movies are newly released, and plenty of movies are easy to find in everyday life. We now watch movies not only in theaters but in our homes with our mobile devices. However, are we fully watching the movies? A single movie contains much more information than one could imagine, and some of them go unnoticed throughout the movie. I understood this during my summer sessions. For my summer session, I took a class called “Understanding of the Film.” In this lecture we learned about the basics of movies and films, how they developed into the movies we know today, and what skills

Am I eccentric? Or, is there someone else like me too? Gruesome curiosity – that is a new word I learned recently. Of course, I have always had a quality of gruesome curiosity in me; I think we all humans do to a certain degree. But learning to put a name to it felt almost like a revelation because I can now explain many of my behaviors by ascribing to it. Like, for example, when I witnessed a young couple violently arguing on the street one evening, I could not help but find myself eavesdropping on their feud as I walked past them. Or, when I witness a traffic accident, part of me is repelled

Son Heung-min's Bending Shot. Even if you are not a big fan of soccer, you are likely to have heard about Son Heung-min, who won the Premier League Golden Boot award in the 2022/23 season. His bending shot is a masterpiece. At first glance, it may seem like the ball is going wide of the goalpost, but it exquisitely curves past the goalkeeper's hands and into the corner of the goalpost. The pressure differential in the air around a spinning ball and the resulting forces can be controlled by the direction and speed of the ball's spin, allowing for its curved trajectory in the air. In

After a challenging semester, you might feel proud and relieved, yet empty simultaneously. At that time, it is essential to find something to do with passion rather than just staying at home during the vacation. The Korean National University of Arts (K-Arts)’s summer session brought me out of the lethargy of repose. The reason why I chose K-Arts among other universities was to gain knowledge in art, which I always desired when studying natural sciences. Also, I wanted to see others who work hard to be an artist, which was my dream during elementary school but has now subsided. K-Arts covers a

There is a TV series named The Good Place that I enjoyed a few years back. In the show, the characters claim that the world became too complicated to judge whether a person is good or bad. You might buy a cup of coffee, but it might turn out to be a product of child labor, or by sending e-mails, you might be contributing to the acceleration of global warming without being aware of it. This idea left a strong impression on me, and I think it is not limited to only the good or bad of a person. Discrimination. This is a concept that has been a hot potato in our society for some time. We learn tha

To Juniper and Asher: May you know that your Grandpa tried. As a young boy, I grew up amongst the Amish culture of northern Indiana during the 1970s and early 80s. This simple country setting provided a panoramic view of large red barns and white two-story wooden houses surrounded by green fields of hay and corn. Dairy cows and large draft horses grazed out in open pastures, and Amish buggies drawn by Quarter horses traveled down long country roads of the Hoosier farmland. The pastoral backdrop of my boyhood would provide me the small-scale lessons of stewardship needed for living in a complex

Ever since the impressive debut of ChatGPT, numerous English teachers have expressed concerns that their jobs have become increasingly challenging, as students may simply rely on the AI system to generate text or use AI-powered translators to convert their Korean writing into English. As a result, teachers may find it difficult to manage writing classes effectively and to evaluate students’ writing skills accurately. While it is true that advanced AI systems like ChatGPT can generate impressive pieces of writing, it is important to remember that they are not a replacement for human creativity

The sun shone down on the open field of vibrant green covering the main quad, filled with the songs of birds, the soft scuttles of squirrels, and the amiable chatting of students. Rays of sunshine, occasionally veiled by wispy clouds, accompanied a gentle breeze. All seemed perfect. When was the last time I had simply enjoyed the sun? Had I even tried something similar before? After a decade of studiously hitting the books, the prospect of simply laying down and relaxing in between classes was too alien to me. Yet here, on the other side of the globe from home, it was the norm. Along the perip

At the start of a new job, enthusiasm and excitement abound. Possibilities seem endless, and the world brims with opportunities. However, as time passes and the job fails to meet expectations or receives a cold market response, that initial enthusiasm tends to fade. The allure of novelty dissipates, leaving a sense of disillusionment. Many individuals lose their drive at this crucial juncture, abandoning their pursuits in search of greener pastures. But what if this decline in enthusiasm is not a sign to quit but an opportunity for transformation? Enthusiasm, though fleeting, can ignite action

About my Research My research area is cognitive psychology. It examines how we think and process information, from receiving it to interpreting it and acting upon it. My area of interest is how people can focus on important information that aligns with their goals while ignoring irrelevant ones everywhere. This ability is especially critical given the overwhelming volume of information in our daily lives. Imagine you chat with a friend in a noisy place, you might need to concentrate on your friend while disregarding the background noise. You could have a conversation with your friend if the no

Learning a new skill can be both challenging and rewarding. For me, learning to play the guitar was a journey that started in 2020. Inspired by my friends in a school band and the legendary guitarist Slash from Guns n' Roses, I embarked on a journey to learn the guitar with no formal lessons. It was tough at first, but with advice from my friends, I gradually learned the basic strumming skills. However, I soon realized that I wanted to do more than just strumming. I wanted to play solos like Slash. It was a challenging goal, and I almost gave up several times. No matter how much I tried, I

For those who have been following my opinion piece over the past couple of years will know of my slight dissatisfaction with my current mode of life. I feel as though I am not doing justice to my youth by spending it in lecture halls every day frantically jotting down notes as if the words might run away. Meanwhile, there is nothing I am doing to prevent my youth from running away. There is so much in the world to see, to experience, and to live. There are so many emotions to feel, and so many lives that could have been but did not. I have always wanted to be a writer, but I guess I found my p
