This year’s POSTECH-KAIST Science War (PKSW) was a culmination of unity and passion. The festival was hosted at the KAIST campus and took place over two days from Sept. 22 to 23, which was the first PKSW after the pandemic. The joyful atmosphere was heightened by the warmth of the sun and the pleasant autumn breeze. There were booths selling a variety of foods and souvenirs. People could also spend time taking pictures or playing carnival games. In particular, POSTECH’s mixology club Eum-ilang had set up their cocktail bars where people enjoyed the delightful non-alcoholic cocktails. The highl

On Sept. 21, POSTECH hosted a spectacular eve festival event in commemoration of the impending POSTECH-KAIST Science War (PKSW).

The eve festival was a vibrant tapestry of sports and artistic activities, with a special emphasis on showcasing the talents of the dedicated athlete

Korea is classified as a “water stress country.” Even though the annual precipitation is approximately 1,300 mm, which is not small, it is concentrated in certain periods and regions, causing inconvenience due to water shortages. Also, the lack of drinking water extends beyond just inconvenience, but life-threatening for some. Nations across the globe are making various attempts to solve this problem. For example, seawater desalination, which uses seawater to obtain drinking water, offers a solution but it still requires fossil fuels to operate the process, and might cause pollution by releasi

In the information age, constructing security systems for protecting information is an important task. Specifically, computing the randomness of random numbers is crucial because it determines every security system’s safety level. Minimum entropy in the field of information theory is commonly used to quantify the randomness of random numbers. The joint research team of Professor Yongjune Kim (EEE), Jiheon Woo (EEE Ph.D. Candidate), DGIST Prof. Young-sik Kim, and Technion Prof. Yuval Cassuto successfully developed an algorithm to estimate the minimum entropy accurately, increasing the accuracy

In 2011, pro-democracy uprising called the Arab Spring spread across the Middle East and Northern African countries. These anti-government protests were successful in some countries, which resulted in overthrown regimes and the start of democratic governments. But in most countries, these protests backfired as the government violently suppressed the demonstration with military forces, and Syrian Arab Republic (Syria) is one of them. Syria is still under the same government that violently executed protestors to end the Arab Spring movement, and Syria has been suffering from a Civil War for the

Competition between the most high-profile names in Big Tech has been rekindled over determining who will dominate the next Social Network Service (SNS) market. Meta recently launched Threads, a new SNS countering Twitter, and Threads aggressively engaged users from Instagram. Meta, in 2021, dropped their former name Facebook and expanded their range of business so far as to metaverse, in accordance with the word Meta which means “beyond”. Amidst these actions of Meta, another movement has been detected in Twitter; its name was changed to X after being acquired by Elon Musk, the CEO of X, and h

POSTECH operates and manages facilities for the welfare of Postechians. The Department of Food Services in the Office of Business Affairs went through difficulties from COVID-19, and underwent a series of changes, and is still dealing with the aftermath. Currently, the department operates restaurants, convenience stores, cafes, the e-sports Colosseum, and more. Haedong-Aurum Hall, Full-course meals, Haedong-Aurum Hall, Geu Yeo Deun, and Oasis especially take up a large portion of Postechians’ dining. Before COVID-19, Geu Yeo Deun had the advantage of offering weekly menu rotations, providing a

The problem of dormitory hygiene arose among students who moved to the dormitory at the beginning of the semester after the summer vacation. Recently, photos of moldy wallpaper and chairs have been posted on an anonymous online community called “Everytime”, and students complain that the hygiene of the dormitory is severe. Many students pointed out the lack of a proper response from the Housing Services, which manages the POSTECH dormitory as the main cause of the issue. Some students complained on “Everytime” about the hygiene problems, saying, “I want Housing Services to properly check the d

LINC 3.0 is one of the divisions fostering entrepreneurship among Postechians. The Postech Times interviewed Hyejin Lee, a principal researcher at LINC 3.0. What kind of work does LINC 3.0 accomplish? LINC 3.0 activates industry-academic cooperation supported by the government, and its full name is Leaders in INdustry-University Cooperation 3.0. Because the initial project had a different direction from POSTECH, we have not participated until LINC+. However, technological innovation leadership was established last year, and POSTECH was selected for LINC 3.0. What business are you responsible f

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

Yoon Suk Yeol, the President of the Republic of Korea, is currently at war with the so-called domestic cartels. His vision to eradicate groups of people seeking to protect their vested interests has had a comprehensive impact on domestic politics. His recent effort to reform the education system that requires students to rely on private tutors comes from a similar motivation. Now, the government’s attention has shifted toward the R&D sector as they set out to reduce two trillion KRW R&D funding in 2024. Lee Jung-num’s office from the Democratic Party of Korea has released a thorough analysis o

In our fast-paced society, expressions like “I want to go home" and "I do not want to go to work" may seem innocent, but they often reveal a deeper issue: holiday hangover or post-holiday depression. Post-holiday fatigue, stress, and decreased productivity can make it difficult to get back into our routines, leading to feelings of anxiety and rejection. Even after the upcoming Korean holiday of Chuseok, we may suffer from a holiday hangover. We need to make various efforts to overcome this illness in a desirable way and get back to our daily routine. Holiday aftereffects, commonly referred to

As Bluetooth earbuds use increases, the number of patients with hearing loss is steadily increasing. According to the Health Insurance Review and Assessment Service (HIRA), the number of hearing loss patients in Korea increased annually from 548,913 in 2017 to 742,242 in 2021. Among them, young people in their 30s or younger accounted for 19.7% of the total. Noise-induced Hearing Loss (NIHL) refers to hearing abnormalities caused by loud and continuous sound stimulation. NIHL symptoms in young people are increasing every year. It is pointed out that the use of sound devices such as Bluetooth e

Following President Moo Hwan Kim’s 4 years at the office, Seong Keun Kim was elected the ninth President of POSTECH. The former President’s term ended on Aug. 31, and the new President Seong Keun Kim will serve from Sept. 1 to Aug. 31, 2027. President Seong Keun Kim received bachelor’s degree at the Department of Chemistry at Seoul National Universities (SNU), master’s and doctoral degree from the Harvard University.

Postechians go through changes and develop as time goes by, and so does POSTECH. Welcoming the fall semester, this article covers the changes in 2023 that can be of help to many Postechians’ daily lives on campus. Changes such as the Group Study Room (GSR) regulations in Tae-Joon Park Digital Library, the on-campus demand-response transportation service and the Undergraduate Study Abroad program. Due to the outbreak of COVID-19, there have been several modifications in POSTECH’s regulations. As a part of the social distancing regulation inside the campus, The GSR has been available for use und

According to Statistics Korea, cancer accounts for the majority of deaths in Korea, in 2021. Among cancers which constitutes 26% of all recorded cases, lung cancer stands out as the most prevalent. In drug screening research such as genetic modification and targeted therapy, scientists widely employ organoids that possess the genetic characteristics of individual patients. However, replicating the intricate internal environment of a lung cancer patient’s body by solely using organoids, remains a formidable task. Recently, a group of researchers including Professor Jinah Jang and Dr. Yoo-mi Cho

Researchers, spearheaded by Professor Su Seok Choi from POSTECH Department of Electrical and Electronic Engineering (EE), have accomplished a remarkable feat in the realm of artificial electronic skin endowed with chameleon-like properties. Their pioneering work, utilizing chiral photonic elastomers (CPE), is poised for publication in the esteemed journal Advanced Materials. Taking inspiration from the chameleon's adaptive color-changing skin, the research team ingeniously engineered CPE with the unique ability to transition colors via self-assembled molecular rotations. This exceptional m

The US is still known as the land of opportunity. Before the pandemic, around 2.5 million immigrants flowed into the country every year from nations around the world. For young international students, US college admission is the first gateway towards entering society in a fairly legitimate and secure way. Therefore, the fairness of college admissions has often been the topic of social controversy. Many parents from within and outside the country seek to have their child placed at a US university, and with all but impressive pool of applicants, these decisions might as well be a “coin flip”. Gi
