input: The BeiDou Navigation Satellite System (BDS, simplified Chinese: ; traditional Chinese: ; pinyin: Beidou weixing daohang xitong) is a Chinese satellite navigation system. It consists of two separate satellite constellations a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.

The first BeiDou system, officially called the BeiDou Satellite Navigation Experimental System (simplified Chinese: ; traditional Chinese: ; pinyin: Beidou weixing daohang shiyan xitong) and also known as BeiDou-1, consists of three satellites and offers limited coverage and applications. It has been offering navigation services, mainly for customers in China and neighboring regions, since 2000.

The second generation of the system, officially called the BeiDou Navigation Satellite System (BDS) and also known as COMPASS or BeiDou-2, will be a global satellite navigation system consisting of 35 satellites, and is under construction as of January 2015[update]. It became operational in China in December 2011, with 10 satellites in use, and began offering services to customers in the Asia-Pacific region in December 2012.

input: (CNN) -- A staff member of the aid organization Doctors Without Borders has died after an attack on a vehicle near the capital of South Sudan, the group said Friday.

The aid worker, Joseph, whose full name has been withheld at the request of his family, died two days after the attack, which took place Monday on a main road outside the capital, Juba, according to Doctors Without Borders.

Opinion: We need an Arms Trade Treaty now

A second employee of the organization was seriously wounded, the group said.

Doctors Without Borders, also known as Medecins Sans Frontieres, said the "exact circumstances" of the attack aren't yet clear, but the car in which its two staff members were traveling was "clearly marked as belonging to Medecins Sans Frontieres."

The organization has requested that South Sudanese authorities "investigate the brutal attack that resulted in the killing of our colleague," said Marcel Langenbach, director of operations for the group.

"We want to emphasize the need to respect international humanitarian law and on the obligation to ensure the protection of humanitarian workers, their property and health facilities," he said.

Doctors Without Borders said it had been working in the region for more than 30 years.

South Sudan officially gained its statehood in July 2011 after separating from Sudan.

input: Valentine's Day was coming. Helen felt hurt and lonely because this was her first Valentine's Day after the divorce .

Helen's twelve-year-old son, Jack, looked at his mother, knowing that this was a difficult time for both of them. In order to make his mother happy, he prepared a present, and handed it to her on Valentine's Day.

It was a beautiful gift package .Helen couldn't believe what was happening. She opened it and took out a lovely card and a small box.

"Now," he said, "read the card." It read as follows:

"I know that this isn't easy for you because it has been a hard year for both of us. I know that Valentine's Day is a special day for people in love. I want you to know that I love you. I know that Valentines are supposed to get chocolate. I went to the store today to buy some for you. Luckily, I got the last piece. I told the clerk it was just perfect."

Helen stood there for a moment and looked at her son. Her eyes sparkled in the light as tears formed in each corner. Jack knew he had done the right thing. Slowly she opened the small box, careful not to tear the paper. She would never forget the moment. She found a chocolate heart that was broken into pieces along with a note:

"I am so sorry that Dad left us, Mom. And all you were left with was a broken heart. But I just want you to know we still have each other.

Happy Valentine's Day!
