Goldiloks and the Three Bears 김현진(10208) : What is the Goldilocks Economy?

"Goldilocks and the Three Bears" is a famous German fairy tale featuring three bears. The story revolves around a young girl named Goldi-locks who enters the bears' house and engages in various activities while they are away.

However, when the bears return and discover that their belongings have been used, they are shocked. Eventually, Goldilocks wakes up and flees the house. This story has gained popularity and is known to entertain and educate children.

Bears. In the story, Goldilocks compares and evaluates three different options before choosing the one that suits her the best. Similarly, consu-mers consider various factors and options and make choices based on their priorities and pre-ferences.

The concept of the Goldilocks Economy can be useful for understanding and analyzing individual choices and economic behaviors. It provides in-sights into consumer patterns, market trends, and marketing strategies. By understanding consumer preferences and needs, businesses can adjust their product development, market-ing strategies, and pricing policies accordingly.

Giving Graphene a New Edge 김준혁(10506)

The result builds on the team's earlier demonstration of a laser-based technique for "writing" an arbitrarily shaped array of waveguides in a crystal [2]. Guided by simulations, they designed a honeycomb structure with twig-shaped edges and predicted that such edges would host nontrivial states. They then realized the structure as a honeycomb lattice of waveguides with a 32-llm lattice spacing. Finally, they used a laser to couple light into the twig edge states and studied how the light propagated through the waveguides. The results show the twig edge states have both topological and "flat band" features-two ingredients that can give rise to intriguing phases of matter.

Salvador Dali : Spain's Surrealist Painter 이지원(10417)

<그림1>

Salvador Dali was born on 1904, May 11th in Figueres, Spain. He was a surrealist painter and a film producer as well. During his school days, he was famous for being a fashionista while attending college. In 1926, he was expelled from school for cheating on final exams.

and from 1929 to 1937, he produced the paintings which made him the world's best known surrealist artist. One of his most famous artworks is "The Persistence of Memory". This painting is known for its striking and bizarre images of melting and distorted clocks, which represent the fluidity of time. From his personal life to his professional endeavors, he always took great risks and proved how rich the world can be when you dare to embrace creativity. His works, completed with a critical approach and paranoid immersion, have a unique perspective and atmosphere that is clearly different from that of

other artists. This is why I decided to research and learn more about Salvador Dali. Dali once said "A true painter is a person who can draw unusual scenes even in the middle of an empty desert. A true artist is someone who can patiently draw a ship even in the midst of the whirlpool of history." This really touched me as an artist as well. Ireally agree that a true artist should be able to draw unusual things with nothing around. Creativity is key in the art industry. I really want to be a great artist just like Salvador Dali. I want to be known as a creative designer. I got lots of inspiration from Dali.

Collaborative Combat Aircraft, the unmanned autonomous aircraft the Air Force plans to spend billions on in the coming years, could extend the operational reach of the crewed combat fleet and offer affordable mass. But the service is looking beyond just kinetic missions for CCAs, two of its top leaders said this week.Gen. Mark D. Kelly, head of Air Combat Command, and Lt. Gen. James Slife, deputy chief of staff for operations, said at a Defense News conference Sept. 6 that CCAs offer a host of options for the combat air forces and in other mission areas. The service is still working to define "what they will do, and what they won't do," Kelly said.

Room-temperature. ambient-pressure Superconductor ILK-991? 정상원(10320)

On July 22, a joint research team from the Quantum Energy Research Center, a domestic private research company, and Hanyang University, Korea University, and William & Mary University in the United States published a paper that said they developed room temperature and ambient pressure supercon ductors on the online thesis pre-release site "ArXiv."

Superconductors are materials that conduct electricity with almost zero resistance under certain conditions.

Mercury became the first material discovered to have this property. Since then, metallic alloys, ceramics and other materials have been found to conduct electricity with almost zero resistance, but only when supercooled. Therefore, in the industry, cryogenic temperatures are realized using refrigerants such as liquid nitrogen and liquid helium, and superconducting materials are limitedly used for magnetic resonance imaging (MRI) devices and magnetic levitation trains.

A room-temperature, ambient-pressure superconductor can conduct electricity without resistance and without either having to be cooled to almost absolute zero or requiring immense pressure. LK-99, if it's the real deal, could be the substance that revolutionizes industries including electronics, energy, and transport. It could pave the way for quantum computing to become a practical reality instead of a laboratory experiment.

Let's understand the cause of the Israel-Palestine conflict from a historical perspective 문지섭(10309)

These days, the war between Israel and Palestine has become one of the hot issues. Forces siding with Israel and those siding with Palestine are colliding globally, each putting forward their opinions.

Delving into the depths of history, the conflict between Israel and Palestine has been a recurring theme since the early 20th century. This ongoing strife has its roots intertwined in the complexities of history, politics, and religious beliefs.

competition over land and resources ignited tensions between the Jewish immigrants and the Arab locals, predominantly Palestinians.

Today, the war between Israel and Palestine continues to fuel instability in the Middle East, with repercussions felt worldwide. The conflict does not only affect the citizens of the two nations but also poses a significant challenge to global peace and stability.

The reasons for the Mongol Empire's penetration into Europe and the societal currents in Europe atthe time

문지섭(10309)

In the annals of world history, the Mongol Empire, under the leadership of Genghis Khan, stands as an unmatched entity, extending its influence across the vast territories of Eurasia. For centuries, historians have pondered the question, 'How could a nomadic tribe from the Mongolian steppes invade, conquer, and rule regions as distant as Europe?'

psychological warfare and deception.

그림<2>

The role of communication in the Mongol conquests was undeniably significant. Beyond military orders, it facilitated the exchange of ideas, culture, and technology. The Mongols established a complex system of relay stations known as the 'Yam', which allowed for the rapid transmission of messages across vast distances. This made possible effective administration and control over the conquered territories.

The Mongol invasion of Europe was a cataclysmic event that deeply influenced the course of world history. Their unprecedented expansion was a result of their military superiority, strategic use of the Steppe Road, effective communication system, and the societal and political vulnerability of Europe at the time.

Facial Palsy 전예린(10521)

FACIALN ERVE PARALYSIS

Many people worry they have had a stroke when they suddenly experience facial palsy.

Facial palsy usually takes approximately three to four days to develop and can take up to several weeks or months to recover, but most people recover within one year. However, facial palsy sometimes cannot be completely cured and people may be left with some residual effects.

and this can typically lead the mouth moving to the opposite side, a common symptom of facial palsy. Loss of taste can also occur, but this improves within a few days. People can also experience loud and ringing sounds. These symptoms are all due to he palsy of the seventh cranial nerve (VII), the facial nerve.

Acupuncture at present, is not proven to aid the recovery for facial palsy. It is important that people are diagnosed appropriately by the doctor first for assessment of the condition and also to identify its cause.

그림<2>

Some examples of residual effects include: facial muscle weakness due to incomplete recovery, facial muscle spasms worsened during recovery, closing of the eyes when the mouth is opened and tears flowing while eating. These residual effects remain during the recovery phase when the nerves do not recover normally, but instead take on a different neural function.

paralyzed eye. Hence, frequent use of eye drops as well as taking good care of the eyes is essential while recovering from facial palsy.

The "Trolley dilemma" Doesn't Work for Autonomous Vehic 김태헌(10508)

그림 <1>

The trolley dilemma, a trolley problem, or translated as 鑛車問題, is one of the thought experiments postulated in ethics, which is a question of which to choose when the brakes fail and an unstoppable trolley has no choice but to sacrifice a few or many people. The trolley dilemma is one of the most popular thought experiments. When a train whose brakes are broken is running on a track, there are five people on it, and if the track is not changed, five people will die, and if the track is not changed, five people will live, but one person on the track will die. The switch is in front of you. What to do with the switch.

One of the most famous thought experiments in all philosophy, this issue was proposed by Philip Foot, a British philosopher, in 1967 as a way to consider difficult ethical choices in many fields. This was raised early in the debate over how to design self-driving cars.

"The re-sults of each vehicle trajectory are not as certain as the two options of the trolley dilemma. And unlike the trolley dilemma that explains the immediate choice, AV decision-making must be pro-grammed in advance."

and everyday traffic scenarios without a binary solution. The researchers also introduce a system to judge a driver's "character" based on agents, actions, and outcomes.

New Lithuim Battery Technology 정예성(10125)

그림 <1> 그림<2>

As the electric vehicle market grows rapidly, demand for lithium, the main raw material for batteries, has also surged. In particular, the use of lithium hydroxide is gradually increasing because it is ideal for high-capacity electric vehicle batteries with a driving range of more than 500 km when fully charged. However, there are limits to expanding lithium production in a short period of time, so the price of lithium has skyrocketed. Accordingly, each country is making various attempts to secure raw materials stably, such as conducting lithium projects and increasing battery manufacturing capabilities. As the term "lithium war" appears, the amount of lithium secured and processing capabilities have recently been mentioned as national competitiveness. However, as there are many advantages, there are also challenges that must be overcome. Most of the world's lithium batteries become waste after use, and only about 5% are recycled. In order to meet the soaring demand for lithium batteries, it is time to pursue more active technology development to find environmentally friendly recycling methods..

Inquiry into the roles nurses play 김나현(10101)

그림 <1>

Watching the movie 'me before you,' let me introduce the process of exploring my career path. In the movie "Me before you," Louisa, the main character in the movie, becomes unemployed when the store where she works goes bankrupt. Louisa, who is responsible for the livelihood of her family, is at a loss. Then she finds a job with a good salary, which is to take care of Will, who was paralyzed from the waist down due to a big accident. Will, whose life is full of gloom, also shows cynical attitudes toward Louisa's efforts.

Meanwhile, Louisa accidentally hears a conversation from Will's parents that Will wants to end his misery by means of euthanasia.

Seatbelts are different when they are in the cars and in the airplane. Different air pressure by the altitute of airplanes 김기후(10302)

그림 <1>

We often encounter different types of seatbelts in frequently used modes of transportation, such as cars and airplanes. Considering that we generally sit in similar ways in both cars and airplanes, it might seem odd that their seatbelts are designed differently. Upon examining why these two types of belts differ in form, we find that each has been designed with a distinct purpose and function in mind.

changes direction. Furthermore, this belt is designed to prevent passengers from colliding with other parts of the car interior and to keep them in an upright position as much as possible.

Viewed in this light, it's clear that the seat belts in airplanes and cars are specifically de signed to suit the risk factors and situations each mode of transportation faces. This suggests that these designs aim to ensure passen ger safety as effectively as possible in their respective environments. Therefore, underst anding why airplane and car seatbelts have different forms is crucial. This reflects the safety requirements of each mode of trans portation, and the following design philosophy. It's a great example that shows the design

principle of prioritizing passenger safety when we use these two different modes of transportation.

also affects the performance of the airplane's engines. Engines generate thrust by combining air (oxygen) with fuel. As the altitude increases and the density of the surrounding air decreases, the efficiency of the engine decreases. To compensate for this, some airplanes use turbochargers or superchargers to increase the pressure of the air supplied to the engine.

How do you learn artificial intelligence?: Artificial intelligence learns through special learning methods. It is machine learning and deep learning. Machine learning and deep learning are both technologies that classify a lot of data, bind them together, and figure out the relationship between top and bottom. The process of selecting that data is done by humans, while machine learning does the work itself.
