They even made a POSTECH Off-Campus Conference Room and have prepared equipment and other amenities so that students can take online classes

70% of the Earth’s surface is taken up by water, and 97% of that water consists of seawater. The seawater’s abundance is drawing attention to it as ‘the’ energy resource for the next generation. Recently the research team of Professor Changshin Jo (GIFT, CE) and Hyebin Jeong (Ph.D. candidate in CE) identified the outstanding performance of chelating agent-applied seawater batteries (SWBs). The research was published recently in the international journal Chemical Engineering Journal. Lithium-ion batteries are widely used in mobile electronics and electric vehicles. But it has a danger of explos

Would there be any optical element that can eliminate the camera lens of the part of the smartphone which protrudes? The answer is yes. In 2019, the World Economic Forum, (WEF) has chosen metalens as one of the Top 10 future technologies. Metalens is a very thin and light planar optical device consisting of an array of nanostructure and has recently attracted so much attention that it is composed of a special issue in the world-renowned journal Nature Photonics. However, due to the necessity of precise technology and high-cost burden, making metalens is not simple. Recently, a research team le

A number of technologies to combat climate change are actively under research. Among them are radical ideas to alter the behavior of the global climate system or to remove carbon dioxide straight from the atmosphere. To meet the goals set by The Paris Agreement, cutting down emissions alone is no longer sufficient, although it would have been a couple of decades earlier. The global emission rate is still on the rising curve, especially for countries that are just emerging out of poverty. To meet the 2-degree goal solely by cutting down emissions would require profound transformations in nearly

Voice phishing has been mainly targeted to the elderly who do not know much about finances. However, in recent years, the amount of voice phishing damage among young people in their 20s has continued to increase. The Financial Supervisory Service (FSS) recently released data titled “The Status and Key Characteristics of Voice Phishing Damage in 2022.” According to this, the amount of voice phishing damage continued to decrease. However, the amount of damage in the 20s age group increased from 6.6 billion KRW in 2020 to 9.2 billion KRW last year 2022, and the proportion of the affected age grou

Over the last few years, POSTECH has reported positive returns and jumps in the POSTECH Endowment. The Postech Times contacted Chang Yun Hyung, the Director of the Investment and Finance Team, to report how the endowment revenue is being utilized by the university and the future direction of the endowment management. The Investment and Finance Team is a department that manages corporate assets, including the POSTECH Endowment, and aims to improve profitability and stability. Seven members work in the financial field along with investment experts in the fields of bonds, stocks, and alternative

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

As technology advances, so does the potential for innovation and a positive impact on various industries and daily life. Artificial intelligence (AI) is at the forefront of this trend, offering vast potential for transformation. However, as with any technology, there is a need to consider and address the ethical concerns that may arise from AI development and deployment. A major ethical concern associated with artificial intelligence is the potential risk of bias and discrimination within its algorithms. These systems learn from the data they are fed, and if that data contains biases, the AI m

On May 11, 2011 a major earthquake of magnitude 9.1 occurred in Japan. More than 18,000 people died and a large amount of radiation leaked from the Fukushima Daiichi nuclear power plant. Radioactive materials in nuclear fuel leaked into the Pacific Ocean, and environmental damage in the surrounding area has not yet been fully recovered. To remove more than one million tons of nuclear waste, fuel rods and radioactive water left at the site, the Japanese government will release the re-enacted contaminated water into the Pacific Ocean. Their opinion argues that the huge ocean will dilute water an

EXchange 2 was one of the most popular TV series in 2022. EXchange 2 is a TV show where five ex-couples live in a house while keeping their past relationships secret. According to GOODDATA Corp, EXchange 2 ranked first on the issue power of Korean TV-Over The Top (OTT) content for three consecutive weeks. Also, many users subscribed to Tving, an OTT service, to watch the series. Yet, EXchange 2 was not the only dating TV show. There were more than 20 dating reality shows broadcast in 2022. Paradoxically, in the survey by the Korea Population and Health Welfare Association (KoPHWA) in 2022, 65.

우리대학 반도체공학과가 7.2:1의 치열한 경쟁률 끝에 40명의 첫 입학생과 함께 출범했다. 이는 재작년 11월 우리대학이 삼성전자와 체결한 ‘반도체 인력 양성 협약’의 일환으로, 반도체공학과 학부생은 삼성전자로부터 등록금 전액과 특별장학금을 지원받아 졸업 후 삼성전자에 채용된다. 우리대학의 강점인 다수의 첨단시설 기반을 적극 활용함과 동시에 향후 반도체 산업을 이끌어갈 △리더형 △실전형 △논리형 인재를 육성하기 위해 반도체공학과 설립에 힘을 실었다.올해 반도체공학과 소속 입학생은 무은재학부 1학년과 동일하게 신입생 기본 교육과정을 마친 후 내년부터 본격적인 전공 교육과정에 들어선다. 반도체공학과 STC 과목으로 △반도체를 위한 물리 △반도체 소자I △반도체소재개론 교과목이 개설된다. 또한, 반도체공학과만의 차별화된 특별 교과목으로 여름 계절학기에만 운영되는 국내외 현장 연수 등을 개설 예정이며, TAB(Technical Advisory Board) 프로그램을 추진해 △IBM researcher △google 전문연구인력 △해외 유수 대학의 전문가 등 9명 이상을 확보하고 있다. 별도의 혜택으로 PSLF(POSTECH Semiconductor Leader F

우리대학은 학부생들에게 더 나은 교육 환경을 제공하고자 등록금 지원을 포함해 다양한 장학금 제도를 운용하고 있다. 장학금 중 한 종류인 근로장학금은 △학기 근로장학금 △시간 근로장학금 △SMP 장학금 △SA 장학금 △RA 장학금으로 구성된다. 이중 학기 근로장학금과 시간 근로장학금의 경우 교내 부서 및 시설에서 근무한 재학생에게 근로시간에 근거한 시급을 장학금으로 지원한다. 지난 2월, 올해 1학기 학기 근로장학금 신청이 진행됐으며 이는 국가근로장학금 제도가 확대됨에 따른 많은 변화를 수반했다. 대표적인 변경 사항은 교내 학기 근로가 국가근로장학금 기반으로 운영된다는 것이다. 국가근로장학금이란 저소득층 대학생에게 근로 기회를 제공하고 장학금을 지급함으로써 안정적인 학업 여건 조성을 목적으로 운영되는 제도이다. 이전까지 우리 대학에서는 교내 학기 근로를 교비 기반으로 운영했고, 2020년부터 한국장학재단과 연계된 국가근로장학금을 운영하기 시작했다. 김지혜(학생지원팀) 씨는 “기존 운영되던 학기 근로제도에서 국가근로장학금 제도로의 안정적인 정착을 위해 작년까지는 학기 근로를 국가근로제도 형태로 운영하되, 장학금은 기존 지급해왔던 지원금액을 유지하기 위해 교비로

우리대학 정대성(화공) 교수 연구팀이 고려대, 경북대와의 공동 연구를 통해 친환경 유기 소재 기반의 수분해 광촉매를 개발했다. 광촉매는 태양광을 이용해 광화학 반응을 촉진하는 물질로, 수소에너지의 원료인 수소를 물에서 분해할 때 사용된다. 수소에너지는 환경오염 우려가 없어 화석연료를 대체할 친환경 신재생 에너지원으로 주목받고 있다. 현재까지 광촉매는 주로 이산화타이타늄 등 무기 소재로부터 제조됐는데, 이렇게 제조된 무기 광촉매는 흡광 영역이 UV로 제한적이고, 일부 유해 물질이 발생하는 문제가 있다. 연구팀은 친수성 곁가지-불소 치환을 이용한 주사슬 개질을 통해 친환경 유기 소재 기반의 수분해 광촉매를 개발함으로써 기존 광촉매가 가진 문제를 해결했다. 정 교수는 “유기 광촉매는 탄소와 수소가 주 구성 원소라는 측면에서 친환경적일 뿐만 아니라, 흡광 영역을 가시광에서 근적외선까지 확장할 수 있다”라며 태양에너지를 완전하게 이용할 수 있는 매력적인 소재가 될 것이라는 기대를 드러냈다.

우리대학 △노준석(기계·화공) 교수 △김주훈(기계 통합) 씨 연구팀이 메타 표면을 이용해 모든 빛에 작동하는 광학 소용돌이 빔을 개발했다. 광학 소용돌이 빔이란 소용돌이 형태로 진행하는 빛으로, 궤도 각운동량을 가진다. 소용돌이 빔은 다양한 응용을 할 수 있어 광학에서 필수적인 존재다. 소용돌이 빔을 만드는 데 공간광변조기(이하 SLM)가 사용되는데, 자외선 영역에서 작동하는 SLM이 없어 소용돌이 빔 제조가 과제로 남아있었다. 연구팀은 기존의 SLM 대신 메타 표면을 이용해 자외선 영역의 광학 소용돌이 빔을 만들 수 있는 편광판을 개발했다. 이 편광판은 자외선 흡수율이 없으면서 굴절률이 높은 질화규소를 사용했다. 또 연구팀은 메타 표면에 입사되는 빛의 편광에 따라 다른 기능을 가지도록 설계함으로써 메타 표면에 저장할 수 있는 정보량을 늘릴 수 있다는 가능성을 열었다. 해당 연구는 국제학술지 Nano Letters에 게재됐다.
