E-sports, 올해도 승리는 우리의 것POSTECH-KAIST 학생대제전(이하 포카전) E-sports 정식 종목인 League of Legends(이하 롤)는 5명의 플레이어가 각자 다른 포지션에서 성장하며 아이템과 레벨을 올려 상대의 기지를 파괴하는 게임이다. 올해 첫 포카전 경기에 출전한 POTENTIAL 소속 E-sports 선수단 팀장 고민우(무은재 23) 학우의 이야기를 들어봤다. 포카전을 위해 어떤 훈련을 했는가?팀이 막 결성된 당시의 우리 팀은 개개인의 실력으로 게임을 풀어가는 팀이었기 때문에 플레이 방식에 팀 단위의 운영 전략을 세우는 데 집중했다. 자유 랭크 게임을 통해 합을 맞춰 나갔고 연습 전 각자 준비한 전략을 발표하고 토론했다. 또한, 여러 사설 팀 및 작년 대표팀과의 연습경기를 진행해 우리의 전략을 적용했고 결과는 훌륭했다. 훈련은 효과적이었고 객관적으로 강한 팀이 됐다고 생각한다. 밴픽 과정은 어떻게 준비했는지?양측 선수들의 선호 픽과 메타 티어를 정말 열심히 분석하고, 수많은 모의 밴픽 시뮬레이션을 진행했다. 도중 우리의 약점을 발견하면 이를 보완할 챔피언 픽과 상대의 약점을 공략할 수 있는 픽을 준비했다. 밴픽 단계부터 영

페로브스카이트 태양전지, 미래의 에너지원이 될까?햇빛을 전기 에너지로 변환하는 태양광 발전의 확대는 거스를 수 없는 세계적 추세로 자리 잡았다. 태양광 발전의 경제성이 이미 화력발전 등 기존의 에너지원들을 따라잡은 가운데, 전 세계 전기 생산에서 태양광 발전이 차지하는 비중은 10년 전만 해도 거의 0%에 가까웠으나, 이후 가파른 확장세를 나타내며 2030년에 10%, 2050년에 20%를 상회할 것으로 전망되고 있다.(DNV GL’s Energy Transition Outlook)우리가 일상에서 접할 수 있는 태양광 패널은 거의 모두 결정질 실리콘 반도체에 기반한다. 반면 연구개발에 있어서 지난 10년간 가장 뜨거웠던 태양전지 소재는 단연 페로브스카이트(Perovskite)라 할 수 있다. 페로브스카이트는 ABX3 결정구조를 가진 물질들을 일컫는 용어로, 결정의 각 부분에 다양한 이온들을 도입해 광 특성 및 전기적 특성들을 손쉽게 제어할 수 있다. 태양 에너지 변환 소재로써 페로브스카이트의 응용 가능성은 2009년에 처음 실증된 이래 2010년대 들어 집중적인 관심을 받기 시작했다. 그 결과 불과 십수 년 만에 26%대의 높은 에너지 변환 효율을 기록했으며

부조리가 판치는 이 세상에 우울해져 갈 때면, 나는 언젠가 진실을 보증하는 엄밀한 과학이 우리를 구원해 줄 것이라는 그 동화 같은 이야기를 다시 떠올려 본다. 일찍이 라이프니츠는 이 세상을 바로잡기 위한 가장 확실한 방법은 오류가 없는 총체적인 추론체계인 ‘보편과학’을 구성하는 것이라 믿었다. 오직 하나의 명료한 의미만을 가지는 보편기호와 이들을 타당하게 조합하는 보편법칙들. 이들로 이 현실 세계와 언어를 체계적으로 재구성할 수 있다면, 옳고 그름은 단지 이 체계를 분석하는 기계적인 일로 깔끔하게 환원된다. 이제 사람들 사이에 논쟁이 있을 때면 우리는 이렇게 외칠 것이다. “누가 옳은지 한번 계산해보자!” 라이프니츠의 이 담대한 기획은 생전에 진전을 보지 못했지만, 그 후계자들에 의해 다양한 형태로 역사 속에 부활해 이어져 왔다. 하지만, 여전히 이 세상은 그가 꿈꾸었던 모습과는 딴판이다. 예상치 못한 세계의 기이한 진실 앞에 이러한 도전들은 번번이 좌절돼 왔기 때문이다. 과학이 발전할수록 웬일인지 자연의 복잡하고 다층적인 면모들은 깊어져만 가고, 인간이 지닌 지능과 의식의 실체는 여전히 안개 속에 머물러 있다. 또한, 우리가 판단해야 할 중요한 문제들은 사

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). Organized by a dedicated student council, the event drew together a diverse group of Postechians, including the supporters, marking the beginning of a grand celebration that resonated throughout the campus. Under a sea of crimson enthusiasm, they came together raising their voices in anticipation of victory in the 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
