BBC News:日本拆樓無噪無塵新技術(shù)適用于密集城市

Hi, welcome to a new week of CNN student news.

I'm Carl Azuz.

First up today, a little history in the making for this famous.

First we are heading over to South Korea.

Today, their country has a brand new leader.

Park Geun-Hye, 61 years old, she won the presidential election in December and by now you've probably guessed why her winner is a stock.

Park Geun-Hye is South Korea's first female president, but this is not the first time that she is connected to the south Korea's presidency.

 

  In fact, her experience around this jobs started younger than all of you.

While the world may not know much of South Korea's first female president, the names of Park Geun-Hye and her family fill her nation's history book.

Born into politics, her father Park Chung-hee was described by some as the country's first dictator.

He seized the power when the military took control of the government in 1961.

Park was nine years old then.

Her father would rule South Korea with iron fist in the next 18 years, overseeing huge economic growth as well as human rights abuses.

Personal tragedy hit Park Geun-Hye when she studies overseas in 1974.

Back in Seoul, her mother was shot dead by someone loyal to North Korea.

The bullet was intended for Park's father.

The failure assassination dramatically changed the course of Park Geun-Hye's life.

Her dream of being a professor was set aside.

She acted as South Korea's first lady, putting the nation's interest above her own.

Five years later there was another assassination attempt at his father.

This time was successful.

His intelligent chief shouted at the dinner party that he wanted South Korea to be a free democracy.

It was two decades later that Park Geun-Hye decided to return to the public spotlight and enlarge her own political career.

Then last December as the head of the conservative party, the 61 year old, who never married and doesn't have children, was elected president with an overwhelming majority.

One of the major challenges as a president would be dealing with North Korea.

She met the leader Kim Jong Il in 2002 in an attempt to end the bad blood between the two families.

Park Geun-Hye says she wants to resume talks with North Korea and restart the aid program on the condition that North Korea abandon its nuclear weapon's program.

But after its third nuclear test, analysts believe North Korea leader Kim Jong-un clearly isn't interested.

Heading to Japan for our next story.

Engineers there are getting rid of an old hotel in Tokyo.

But not like that.

They are trying a different demolition approach.

Say hello to the incredible shrinking building.

This hotel is 40 stories tall, and engineers are taking it away one story at a time.

May not look much in the outside.

Check out what would happening in the inside.

The crews go floor by floor using temporary jacks.

Those hold up the higher floors while the workers take out beams, support columns and debris.

Then the jacks move what's left, and the crew moves on.

Why doing it this way?

It's a lot quieter than the standard demolition which keeps the neighbors happy, and no chance of explosion damaging other buildings.

It's also more expensive and it takes longer.

In this case, an estimate of six or seven months.
