Question:
Article:Nitcharee Peneakchanasak was announced on a TV talk show as winner of the competition named Best Job in Thailand.
She was chosen for the six-month "happiness observer" post from hundreds of applicants, the hospital says.
Supporters across Thailand had been rooting for the 21-year-old who lost her legs in a 2011 rail accident.
The World Medical Hospital in Bangkok which offered the job is only four years old and has attracted widespread attention with its unique job offer.
According to a hospital spokesman, Nitcharee or "Thun" was selected from more than 800 applicants who submitted video applications for the job.
"I think I won the competition because I was true to myself. I showed them that this is what I love doing. Plus, I had overcome the [accident], which was quite a unique experience," Nitcharee told the BBC's Thanyarat Doksone.
"I was very surprised because I thought I was quite young and inexperienced, compared to other candidates. But I'm very glad because I love talking to people and I want to talk to the patients. I dreamed of being a psychologist."
Nitcharee is currently studying journalism at Thammasat University in Bangkok.
Part of her duties will be to observe patients and talk to them to help the hospital administration find out more about their needs. She will also be asked to write inspiring stories on Facebook.
"We believe that doctors can only treat physical conditions of patients but we rarely know what's on their mind," the spokesman told the BBC. "If we know what they want and help them, they will recover more quickly from their illnesses.
"Thun has experienced a tragic event that had a huge impact on her but her mind is so strong. She went on to speak to others and became their inspiration to fight. We're proud to have her," he explained.
In 2011, the then teenage girl lost both her legs when she fell off an MRT platform in Singapore in front of an oncoming train.
Her story gained huge attention both in Singapore and Thailand at the time.

Summarize the main points of that article.

A Thai woman who lost both her legs as a teenager has won a job in a hospital which will pay her one million baht (Â£23,000; $29,000) a month.
input: Article: When asked by BBC reporter Colin Paterson whether video games should be an Olympic sport, Rob Pardo told BBC Radio 5 Live: "There's a very good argument for e-sports being in the Olympics."
Mr Pardo said: "Video games are well positioned to be a spectator sport."
Some video game events already attract thousands of spectators.
A recent video game tournament held in South Korea filled a stadium with 40,000 people.
He said: "Look at these professional gamers - [their] reflexes are lightning quick and they're having to make very quick decisions on the fly."
But he also said people would need convincing that video games can count as a sport.
Mr Pardo said: "If you want to define sport as something that takes a lot of physical exertion, then it's hard to argue that video games should be a sport."
"But at the same time, when I'm looking at things that are already in the Olympics, I start questioning the definition," he added.
For e-sports to appear at the Olympic Games, the International Olympic Committee would first have to recognise video games as a sport, which is highly unlikely.
Board game fans have previously called for chess to be an Olympic sport, but the IOC said it is a "mind sport" and therefore not welcome in the Olympic Games.

Problem: The 71-year-old was found unconscious in her Los Angeles home on Tuesday afternoon.
A statement released on her website late on Friday said the singer was "resting comfortably".
It is still not clear what Joni Mitchell is being treated for.
"We are encouraged by her progress and she continues to improve and get stronger each day," the statement said.
In December, Canadian-born Joni Mitchell told Billboard magazine that she had a rare skin condition, Morgellons disease, which prevented her from performing.
"I can't sing any more - don't miss it. I can't play any more - don't miss it. I've got all these instruments laying around and hopefully one day I'll pick them up," she was quoted as saying.
Morgellons is a controversial condition and is not recognised by mainstream medical authorities.
Sufferers say it is characterised by crawling and stinging sensations under the skin but many in the medical community believe it is a psychiatric disorder.

input: Article: The first impressions of a new-look Saughton Park and Gardens will go on display to the public on Tuesday between 16:00 and 20:00.
Visitors will be able to ask about the plans with designers Ironside Farrar.
The consultants, who were involved in the design of The Helix in Falkirk, have been appointed to develop a design plan for the Â£5.3m park renovation.
Lesley Hinds, Edinburgh city council's environment convener, said: "This is a very important stage in the project to revive Saughton Park and its wonderful gardens, as we get a first glimpse of designers' vision for restoring it to its former glory.
"We have been eager to involve local people throughout this process, and now the community can come along and tell us what they think of these exciting new ideas."
The design team also includes Sutherland Hussey Architects, Peter McGowan Associates, Richard Shorter Architect and David Narro Associates.
In 1908 the park was redesigned for the Scottish National Exhibition, resulting in a range of new features, including sports facilities, a bandstand and winter and botanical gardens.
A project to restore the park secured almost Â£400,000 from the Heritage Lottery Fund to develop a design plan.
