The Intergovernmental Panel on Climate Change (IPCC) suggested that the global community should achieve net-zero emissions by 2050 to give the world a chance of limiting the global temperature rise to 1.5℃. The net-zero emission is broadly the same as carbon neutral: CO2 emissions are being generated, but they are offset by the same amount being removed by technology. At the current state, to reach net-zero emission, CO2 emissions should be reduced, but offsetting emissions are also necessary. Replacing fossil fuels with “renewables, hydrogen and nuclear” is the most urgent task for each count

On March 23, POSTECH announced a plan for the creation of the “Pohang Bigdata-AI Innovation Center”.

On Feb. 23, POSTECH announced that it will shift to face-to-face classes from the eighth week (April 11) of the Spring Semester.As the vaccination rate in Korea reached 80%, the Ministry of Education has recommended universities to resume face-to-face classes, due to the concern of “accumulated learning deficits.”From the midterm exam period, professors can choose between staying non-face-to-face or converting to face-to-face. The exact plan for each course will be announced by the individual course instructors. Students are allowed to move into the dormitories from March 31 to April 3. April

In a TV address on Feb. 24, Vladimir Putin, president of Russia, declared that Russia feels a constant threat from Ukraine. Immediately after the announcement was made, the military headquarters of Ukraine were attacked. Afterward, troops from Russia, Crimea, and Belarus crossed the border of Ukraine. Putin banned the terms of “war” or “invasion” in Russian articles and broadcasts, insisting the attack is a “special military operation”. According to Putin, the attack was for the “demilitarization and de-Nazification” of Ukraine and for protecting Russians from genocide in Ukraine. However, Vol

Think of an ambulance carrying an emergency patient. It successfully passed the suburban area with the help of the ground-traffic control center. However, in the urban area, the patient is running out of time due to traffic congestion. Dramatically, the C-ITS integrated control center manages the situation and changes all traffic lights on the ambulance route to the green. The patient safely arrives at the hospital on time. This is just an example of what the Cooperative Intelligent Transport System (C-ITS) does.The C-ITS is a next-generation model of the Intelligent Transport System (ITS). Th

Humankind and the UniverseHumankind has been observing the universe since the ancient past. In 3000 B.C., many civilizations such as the Sumerians, who carved stars on clay plates, observed and recorded the movements of the sun, moon, and stars in the sky. Egyptians observed the sky and predicted the flooding period of the Nile River, and the ancient Greek philosophers such as Thales, Aristotle, and Ptolemy observed the sky and mathematically organized the movements of stars, systematizing the field of astronomy.The desire to seek the origin of the universe led to the development of a technolo

Despite being in an era of a smooth logistics system, we have experienced the shock of shortages; not being able to buy or having to wait days for masks, smartphones, etc. Shortages occur when demand is greater than supply. There are various reasons for the shortage; lack of labor force, lack of materials, circulation problems, and sometimes it is just a kind of marketing. For whatever reason, shortages continue to occur, and we must seek the causes and measures to be taken. Here are two shortage cases that occurred recently.Diesel exhaust fluid shortageOn Oct. 11, Chinese customs officials an

From 2020, the COVID-19 pandemic has stopped the cultural industry from providing cultural products such as offline concerts and overseas trips. Although cultural facilities were busy catching customers by operating vaccine pass centers and introducing discount events for ticket prices, there were still restrictions such as those on gatherings and business hours which made consumers hesitate. However, from Nov. 1, the Korean government implemented the “living with COVID-19” strategy to abolish all restrictions in three stages. As the restrictions are being lifted, the cultural industry is prep

On Sept. 27, officials from POSTECH, Apple, Gyeongsangbuk-do, and Pohang-si signed a memorandum of understanding (MOU).

On Sept. 8, Naver and Kakao’s stock price showed a sharp decline of 7.87% and 10.06%, respectively. The cause of the decrease was an announcement made by the financial arms on Sept. 7 about regulations on Big-tech. Big-tech companies are prevailing IT firms, including Naver and Kakao. They flourished amid the non-face-to-face era triggered by COVID-19. However, their excessive market dominance and overuse of power became a problem.On Sept. 7, the financial arms judged Naver Financial and Kakao Pay’s recommendation on funds, insurance, and other financial products offered to customers on their

The Big Short (2015) is a biographical drama film which portrays how a few financial industry professionals predicted the real estate bubble before the subprime mortgage loan collapse in 2008. Few investors were aware that the U.S. housing market was built on a bubble that might burst within a few years. The film explores the stories of these investors separately but also in parallel.SynopsisMichael Burry, a manager of the hedge fund Scion Capital, carefully analyzes the data of the subprime mortgage loan, a financial product designed to offer unlimited home loans to credit borrowers who lack

Recently, I was depressed because it seemed that I had done nothing during this summer recess. I did not participate in the Undergraduate Research Program (UGRP) nor any internship programs. Rather than partaking in various programs provided on or off campus, I wanted to study alone during this recess and cultivate my academic understanding. I had a lot to learn, such as financial mathematics, combinatorial analysis, Python, and Spanish. Despite studying these disparate fields on a planned basis, I was perturbed about what I was doing. My studies did not seem to be headed towards one consisten

The 17-day long Tokyo Olympics came to an end with a closing ceremony on Aug. 8. The Tokyo Olympics was unprecedented compared to the previous Olympics: it was postponed for a year due to COVID-19, and spectators were banned after a state of emergency was declared on July 8 in Tokyo. Nevertheless, the Tokyo 2020 Olympics ended successfully with lots of memorable moments and new records. Team USA secured the top spot on the table by winning 39 gold medals, 41 silver medals, and 33 bronze medals, followed by China and Japan in second and third place. Team Korea ranked 16th place with six gold me

From June 14 to Sept. 3, Postechians are given a summer recess. During this time, Postechians participate in various activities. Some participate in internships to gain social experiences and experience office life before starting their careers. Some students conduct research in laboratories on campus to cultivate academic depth. Others prepare for achieving various certificates that they could not prepare for during the busy semester. POSTECH has a long summer recess of 82 days, so it is a good time for Postechians to either gain out-of-school experience or to rest and recharge. To find out h

Cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin have become popular in recent years. A cryptocurrency is a computer code generated by publicly available software that allows people to store and send value online—the code groups transactions onto the “blockchain”, a public record. Blockchain is a large file storing every transaction ever made. This makes cryptocurrency highly secure and private. One can “mine” cryptocurrencies using the methods such as POW and POS. POW (Proof of Work) is a method that uses hardware (GPU, ASIC mining machine) that processes hash operations to ensure tha
