Marijuana usually refers to plants such as hemp or cannabis that have psychological effects on the human brain. The most well-known usage is to dry the marijuana and smoke it. The ‘Delta-9 tetrahydrocannabinol’ component of marijuana, also known as THC, invokes cognitive hallucinations. Many popular musicians such as The Beatles, Muse, Green Day, Wiz Khalifa, and Lady Gaga have used it to get musical inspiration. ‘Young, Wild, and Free,’ and ‘Mary Jane Holland’ are songs about musicians’ personal experiences with marijuana. According to people who have experimented with marijuana, it makes it

The Summer Experience in Society (SES) Program is an internship program provided to every undergraduate student in POSTECH, in which students volunteer for internships with firms, research institutes, etc. during the summer holidays. I joined the SES Program last semester and worked at a major company during the summer vacation. I learnt a very special lesson which I wasn’t intending to, but still a very important lesson that cannot be taught at a university.It is just too early to finish learning and get a job right after graduating university. We all indeed studied hard during high school in

During the last seven years, I have been teaching coding online and offline under the name of ‘Coding Everybody’, and the most frequent question that I have received was ‘how to study coding’. There is no answer to this question and my thoughts are changing continuously, but my current opinion is this.Firstly, I would like to suggest we should ponder on the reason why we study. The ultimate reason why we study is not because of school grades, but to solve problems in our lives. If the problem itself is more challenging than studying, then studying becomes the way out to solve the problem, and

PRODUCE 101 makes me uncomfortable even after the airing, as well as during the airing. When I first saw the music video of 'Pick Me', I felt sorry whenever four triangle stages filled the screen. It was miserable for me to see the appearance of F grade performers who were pushed out from the stage. They just appeared right before the end. It is cruel to grade performers. People are sensitive for being rated. However, people consume well-rated contents once they become subjects. The 'national producer' would have cheered in the breathtaking tension when the girl/boy who they 'picked' made thei

When I was young, I dreamed of being a competitive gamer. Like the majority of boys at my age do, I like to play computer games. My older sister and brother also liked to play games, so I was influenced by them and learned how to play games through them. As a gamer, top level players like Flash or Faker are the object of admiration and mentor to average players like me. I played various kinds of games but I was not talented in games like top-tier gamers were. I lacked both time and talent to play games at a competitive level, so I thought it would remain as a dream forever.I used to play an on

Leaders, regardless of the scale of their organization, expect that members of the organization fulfill their responsibility, show passion about their work, and commit to the organization. If members work hard not because of external pressure or monetary reward but because of internal and voluntary motivation, the organization will be able to achieve its goals based on mutual trust. Leaders may elicit various positive and negative emotions, but in this column, I would like to focus on the former, particularly other-praising emotions. All human beings can be selfish, but at the same time, they

The mass media nowadays are emphasizing how all the youth are engaged in getting high GPAs, and high test scores such as TEPS, TOFEL and TOEIC to get into ‘good’ companies. However, I don’t think getting standardized into these means of evaluation is beneficial. What is more important is what we experience and learn in our lives. No two people in the world live the same life. Hence, what distinguishes us from anybody else is our own ‘story.’ Everybody has their own story and are valuable because of that. Hence, I would like to suggest to the readers to have new experiences that will nourish an

2017 Presidential election was held on May. 9. The election schedule was originally scheduled to be held on Dec. 20. However, early election was determined because of the impeachment of former president Park Geun-hye. Not every Postechians were able to vote in the election. According to the constitution, person over the age of 19 in American age can vote. In other words, since Koreans have different age system, some freshmen and some sophomores have no right to vote. Number of people aged 17 years old in American age was 629,629, according to statistics conducted in April, 2016. This means alm

Landscape is a tract of land with particular features, which are usually products of human modification, and it exists and transforms in diverse forms and scales from a single statue, monument, and building to a sum of human-made structures such as rural settlements and particular urban sections. In addition to denoting tangible material settings, the term is also used in metaphorical ways (e.g., political landscape in popular and media discourses). Landscape comprises an important research theme in cultural geography, a sub-discipline of human geography concerned with cultural artifacts, prac

“Time is gold.” This is a famous quote from Benjamin Franklin. This saying expresses the importance of time by comparing time with gold. Twenty-four hours a day are given to every person. The point is using time effectively. However, it does not mean that we need to rush all the time. These days, people push themselves to be in hurry. They are sometimes afraid to get free time because they believe they are wasting their time. We are getting used to rapidity. For instance, let’s imagine that you want to know the meaning of the English word “Brexit.” In the past, we first found thick, heavy dict

For some years, the word 'innovation' turned into a jack-of-all-trades term that every part of the society is now aware of. Politicians use it in their campaigns, presenters use it, and even the cities’ marketing teams started putting it on city-promoting posters. The word surely sounds good, and one would have been able to hear it even in talks of country-scale importance. But somehow I could not see myself using the term in front of people. In a recent talk given by an entrepreneur that I attended, I was able to confront the reason. The presenter remarked at one point, “Difficult, but not im

“I am afraid I am busy.” This is a typical answer from most scientists about participating in the promotion of public understanding of science. As one of them, I deeply agree with such response. Researchers are busy with endless study and work. However, such complicated research is hardly understood by the public and seldom enters the spotlight. Unpopular research struggles to secure funding from policy makers and the government, and researchers get busy with having to start another project, hoping for improvements this time. Though there may be several stages being skipped, what we see here i

The Supreme Court delivered a death sentence to a male in his 20s who killed the parents of his ex-girlfriend and raped her. It was the only death sentence delivered by the Supreme Court during last three years. The man slapped his ex-girlfriend’s face because she insulted one of his friends, which led her to break up with him. However, he bore a grudge against it and caused violence to her. Her parents made a strong protest to his parents, which made him commit this awful crime. This is an extreme example of dating violence.Actually, dating violence has become one of the major issues in Korea

On Mar. 24, salvage of the Sewol Ferry began after a long controversy between the government and bereaved families, with a preparation of more than a year. Two days after, on Mar. 26, the whole Sewol Ferry was brought up to the surface, and drainage work has started. I am writing this column on Mar. 26, and the ferry is expected to be brought on shore by Mar. 28 at the earliest. There are still debates and controversies about the timing and process of salvage, but what touched my heart was neither the politics nor the technical issues. I was reminded of the day the Sewol Ferry went down. Apr.

Last year, Gachon University Gil Hospital adopted Watson for Oncology to diagnose a patient with colorectal cancer with accuracy similar to that made by doctors. The patient had third stage colorectal cancer and had laparoscopic surgery. With the data all input, Watson for Oncology chose FOLFOX and CapeOX for the main treatments, which are general anticancer drugs.The recent introduction of Watson for Oncology, a computer-based medical consultation aiding system for cancer, into the domestic market has initiated an enthusiastic discussion about A.I. (Artificial Intelligence) and the future of

About a year ago, I was a freshman of POSTECH. Last year was such an important time because I thought it was time to enter a new world and no longer limit “studying” to school. In my memory, this young student, filled with excitement, expected an adventure ahead of him. It was too short for a young student wanting to experience everything in one year, and now, it is time to become a sophomore. Now, there are new freshmen hoping for a new change and wonderful experiences. In order to help them spend a wonderful freshman year, I would like to introduce some activities that made my freshmen life

As every semester passes, I always get reminded of how fast the time goes by, and reflect on what I have done over the last semester. As another semester passed after becoming a junior, I came to think that despite of what I had learnt so far, there was nothing which I was especially good at. Despite of coming to POSTECH where people around me would tell me that I have achieved one of the major goals throughout my life, the fact that I had no specialty was a big problem. The problem of looking for why was not so hard. The most frequently asked question for taking any lecture is: “Does the prof

In some countries, teenagers have jobs while they are still students. Some adults and teenagers might think this is a good idea. However, I disagree with this idea for two reasons. First, teenagers are young. They should be supported from their parents or teachers to find and pursue their dream. Their most important task should be developing themselves mentally because many teenagers have problems standing the pressure of life. Second, the discrimination of the employers would harm the teenagers because the employers tend to undermine teenage employees. Teenagers are placed in a dangerous situ

Frankly speaking, when I was volunteering as a newbie reporter of The Postech Times, I was careless and irresponsible. I definitely had merit in English skills accumulated during my four years of studying abroad in New Zealand, and I thought using this merit would enable me to maneuver into The Postech Times. The fact that I was a freshman at that time induced me to consistently seek for new activities that would bring changes in my life, without being aware of the responsibilities that lie beyond them.Being a reporter in POSTECH is tough because you have to get yourself organized. Once you ar
