Through the following four cultural relics, the world has known about Korea's cultural treasures.

Pulguksa Temple

    Pulguksa Temple plays an important part in the history of Korean temples. The building of Pulguksa Temple began in 751. In the year 774 the large temple was finished, becoming an important center for Korean national-protection Buddhism(佛教). The way used to create the store structure gave the temple a look of beauty. The building thus represents the excellent Korean sculpting(雕刻).

Sokkuram Cave

    Sokkuram Cave is a man-made cave, which has been sculpted from white stone in special sculpting ways. In the cave, a seated Buddha is the main statue. On the walls around him are found 38 other statues and the Four Heavenly Kings. This stone cave is one of Korea's greatest places, built when Shilla's religion, science and sculpture were at the height. It shows Shilla's knowledge of math, physics and art.

Haeinsa Temple

    Haeinsa Temple's Changgyong Panjon (藏经板库) is a world-class cultural treasure. It has 81,340 wooden blocks. Millions of Chinese characters were caved on the blocks. In addition to its artistic value, it is famous as the oldest Buddhist canon(教义)in the world today. The building is beautiful. What's more important is that its design allows for natural wind as well as temperature control. Each book is 69.5cm in width and 23.9cm in height. There are 23 lines on each of the blocks and each line contains fourteen characters.

Changdokkung palace

    Changdokkung palace, one of the five places of the Chosen Dynasty, was built in 1405. The oldest structure is Tonhwammun Gate. Other ancient buildings include Injongjon hall, Sonjongjon Hall and Taejojon Hall. The back garden for kings remains a great example of the ancient Korean scenery.

    Stop wasting your time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.

    The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.

    You cannot be successful without first developing your self-esteem (自信心). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.

    You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.

    Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.

    If you associate with positive-thinking people, you are definitely going to achieve success. On the contrary, the opposite happens. We are responsible for finding, planting, and nurturing (培育) the seeds that contain future victory, born from setbacks (挫折).

    In short, in all areas of your life, whether they are financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.

    Reading may be fundamental, but how the brain gives meaning to letters on a page has been a mystery. Two new studies fill in some details on how the brains of efficient readers handle words. One of the studies, published in the April 30 Neuron, suggests that a visual-processing area of the brain recognizes common words as whole units. Another study, published online April 27 in PLOSONE, makes it known that the brain operates two fast parallel systems for reading, linking visual recognition of words to speech.

    Maximilian Riesenhuber, a neuroscientist at Georgetown University in Washington, D. C. , wanted to know whether the brain reads words letter by letter or recognizes words as whole objects. He and his colleagues showed sets of real words or nonsense(无意义的词语)words to volunteers undergoing FMRI scans. The words differed in only one letter, such as “farm” and “form” or “soat” and “poat”, or were completely different, such as “farm” and “coat”or “poat” and “hime”.The researchers were particularly interested in what happens in the visual word form area, or VWFA, an area on the left side of the brain just behind the ear that is involved in recognizing words.

    Riesenhuber and his colleagues found that neurons(神经元)in the VWFA respond strongly to changes in real words. Changing “farm” to “form”, for example, produced as great a change in activity as changing “farm” to“coat”, the team reports in Neuron. The area responded slowly to single-letter changes in made-up words.

    The data suggests that readers grasp real words as whole objects, rather than focusing on letters or letter combinations. And as a reader's exposure to a word increases, the brain comes to recognize the shape of the word. “Meaning is passed on after recognition in the brain”, Riesenhuber says.

    The researchers don't yet know how longer and less familiar words are recognized, or if the brain can be trained to recognize nonsense words as a unit.

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name — phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie(自拍照) in front of a car accident site and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. "Constantly bending your head to check your cell phone could damage your neck," Guangming Daily quoted doctors as saying. "The neck is like a rope that breaks after long-term stretching." Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

New discoveries and technological breakthroughs are made every year. Yet, as the information industry moves forward, many people in society are looking back to their roots in terms of the way they eat. A "locavore" movement has emerged in the United States. The movement supports eating foods grown locally and sustainably, rather than prepackaged foods shipped from other parts of the world.

Experts hold that eating local has many merits, and is expected to become a trend featuring sustainability. Erin Barnett is the director of Local Harvest, a company that aims to help connect people to farms in their area. By eating local, she argues, people have a better and more personal understanding of the impact their food consumption has on the rest of the world. "There is a way of connecting the point, where eating locally is an act that raises our awareness of sustainable living," Barnett says.

The United States' agricultural output is one of the highest in the world, says Timothy Beach, a professor of geography and geoscience at the University of Texas in Austin, Texas. "There's just no other place on Earth where the amount of input is so productive," Beach says of American agriculture. "Nobody can cut off the food we need."

However, the US food system is not sustainable because of its dependency on fossil (化石) fuels, says Beach. Equipment used on "extremely productive" farms is quickly consuming Earth's natural resources, particularly oil. Additionally, the production of agricultural supplements (补充剂)，such as fertilizer, uses large amounts of energy.

The world has used close to half of the global oil supply, Beach says, and the second half will be consumed at an even faster rate because of the growing population and economic development. Although many businesses are experimenting with wind, solar, and biofuel, Beach says there's nothing that we see on the horizon that can replace it. "There is no way on Earth we are using fossil fuels sustainably. Then we have to reconsider the impact of eating local," he says.
