Stencil is an art technique that illustrates an image by passing ink over a plate with holes. The semiconductor industry also has a similar technique. Stencil lithography is a method to pattern on a substrate by depositing metals through a shadow mask. The technology is normally used to make nano-sized devices or circuits; however, it is difficult to apply on curved surfaces. The research team of Professor Seok Kim (ME), Prof. Dae Sung Chung (CE), and Ph.D. candidate Sangyeop Lee invented the shadow mask for stencil lithography that can be applied on flat and curved surfaces and can be attache

In Aug. 2020, heavy rainfall and a substantial water release in the Seomjin River Dam caused a tremendous flood, causing 160 billion KRW in damage. One of the primary issues that worsened the damage was the failure in the dam operation, as the operators did not discharge enough water before the heavy rainfall. Could this have been averted if we knew in advance and took measures? Research led by Professor Jonghun Kam (DESE) and Eunmi Lee (integrative MSE/PhD program in DESE) in the Hydro-Climatology Research (HCR) group, explored the efficient operation of dams using deep learning and verified

In the intricate tapestry of global economies, the United States and Japan stand as economic behemoths, each exhibiting consumer patterns that defy conventional economic views. The juxtaposition of their consumer patterns reminds us that the dynamics of the marketplace are influenced by a myriad of cultural, economic, and societal factors and cannot be explained by simple textbook teachings. The United States and Japan are showing opposite monetary policies and consumer behaviors. The central bank of the United States, the Federal Reserve System (Fed), has raised interest rates to 5.5%, the hi

What does SAG-AFTRA mean? As the abbreviation of Screen Actors Guild – American Federation of Television and Radio Artists, it represents the employees who produce, report, write, host, or announce news for web content, videos, and podcasts. Covering approximately 160,000 media professionals worldwide, it deals with the issue of performers who did not quite earn enough.

The existing Minimum Basic Agreement (MBA) between the American Association of Producers (AMPTP), a

The Residential College (RC) is undergoing significant alterations since its establishment: the construction of common spaces like group study rooms and a fitness room. The reason for the renovation is the overall and rapid decrepitude of the RC building due to the characteristics of declining public facilities. The construction commenced on Oct. 30 and will last until the end of Jan. 2024. This is the first stage of the whole renovation of the RC which includes a room remodeling next summer, and the main facilities in this work are a coin-karaoke, a fitness room, and a group study room equipp

Last November, the vibrant campus of POSTECH was abuzz with fervor as students gathered to participate in a large-scale vote to elect the student union president and dormitory union president. The Student Leadership Election Committee diligently announced the chosen candidates for each position, setting the stage for a democratic exercise that would unfold with its own twists and turns. Initially, the candidate for the student president secured 331 votes in favor, 35 against, and 11 invalid votes out of the total 337 votes, while the candidate for the dormitory union president secured 334 vote

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

The Ministry of Environment (MoE) said on Nov. 7 that it would withdraw the regulation on using disposable paper cups operated by food service businesses such as restaurants, cafes, and group catering centers. As a result, the guidance period for the prohibition order on plastic straws and plastic bags has been extended virtually indefinitely. The use of paper cups and plastic straws was given a one-year guidance period as one of the additional regulations on disposable products that took effect on Nov. 24 last year. However, the MoE announced a policy to withdraw existing regulations ahead of

The term “Megacity” has evolved to signify a “very large city,” with criteria shifting from a population of three million to eight million and now standing at 10 million. According to the United Nations’ annual “The World Cities” report, the global count of megacities is projected to reach 43 by 2030, defining cities with populations exceeding 10 million. Professor Byun Chang-heum of Sejong University emphasizes that the current discourse on megacities is not about uniting small and medium-sized cities but revolves around fostering metropolitan economic zones centered on major urban hubs. This

Vox, an American news and opinions media, recently published an article on Brutalism. In short, it addressed the prevalent issue of why numerous modern campus buildings end up appearing unattractive and gloomy. In many ways, the article was reminiscent of the buildings in the POSTECH campus which can be characterized by somber, gray rectangular structures devoid of artistic merit. In fact, such buildings, seemingly constructed more for pragmatic reasons than aesthetics, can also be found in Seoul National University, KAIST, and of such campuses around Korea. Emerging from the 1950s, Brutalism

Have you ever seen an aurora? Seeing an aurora is on many people’s bucket lists. Also known as Northern lights, it is an atmospheric phenomenon that creates enchanting dancing waves of light associated with countries surrounding the Arctic like Canada, Russia, and Norway. If you have planned to visit these countries to see one, you may have to change your plane. Just this month, the North Pole was not the only place showing these mesmerizing shining skies. Parts of the UK, Ukraine, and Slovakia were spotted with the borealis. What makes this possible? According to the experts, southern sightin

How to Stop Time is a high-stakes romance novel by Matt Haig that explores the idea of finding purpose in life. The book starts with a ground-breaking confession from a man called Tom Hazard about his bizarre physical condition which, later in the century, will be known as “anagaria”. This condition prevents him from aging. He appears to be a normal 40-year-old man but has actually lived for over 400 years. This condition does not make him immortal but gives him a different, much slower, biological clock than normal human beings. Due to this, however, he keeps having to move from one place to

3년 간의 비상대책위원회 체제로부터 작년 정식 총학생회 체제로 전환된 것에 이어 올해도 총학생회장단 선거 출마자가 나왔다. 2024년도 제38대 총학생회장단 선거에 정후보 고태영(소재 20)·부후보 박현용(컴공 20) 학우로 구성된 ‘내일’ 선거운동본부(이하 선본)가 단일 후보로 출마했다. 이어 생활관자치회장단 선거에도 정후보 임승현(융공 21)·부후보 서영서(컴공 22) 학우로 구성된 ‘엘리펀트’ 선본이 단일 후보로 출마했다.선거에 앞서, 지난 2일 총학생회장단·생활관자치회장단 후보의 공약 발표회가 있었다. 발표회는 △각 후보자의 소견 및 주요 공약 발표 △참석자 질의 및 후보자 응답으로 구성됐다. 선본 ‘내일’은 △군 인권 문제 해결을 위한 특별기구 설치 △학생과 학교 사이의 소통 강화 △총학생회 정회원 혜택 강화 등의 3가지 공약을 제시했다. 고태영 학우와 박현용 학우 모두 1학년 때부터 총학생회를 포함한 여러 학생 활동을 빠짐없이 이어왔고, 학생들을 위해 행동한다는 자부심을 느껴 총학생회장단이라는 자리에 도전하게 됐다고 전했다. 이어지는 질의 시간에 “우선순위를 두고 있는 학내 문제와 그에 대한 해결 방안이 있냐”라는 질문이 있었고, ‘내일’ 선본의
