？？A patient on the brink ofdeath has received the world's first self-contained artificial heart-a bat-tery powered device about the size of a softball that runs without the need forwires, tubes or hoses sticking out of the chest.？？？？
？？ Two surgeons from the University of Louisvilleimplanted the titanium and plastic pump during a seven-hour operation at JewishHospital Monday. The hospital said the patient was "awake andre-sponsive" Tuesday and resting comfortably. It refused to releasepersonal details.
？？ The patient had been expectedto die within a month without the operation, and doctors said they expected theartificial heart to extend the person's life by only a month But the device isconsidered a major step toward improving the patient's quality of life.？？
？？ The new pump, called AbioCor, is also a technological leap from the mechanical hearts used in the 1980s,which were attached by wires and tubes to bulky machinery outside the body. Themost fa- mous of those, the Jarvic-7, used air as a pumping device and wasattached to an apparatus about the size of a washing machine.？？
？？ "I think it'spotentially a major step forward in the artificial heart development,"said Dr. David Faxon, president of the American Heart Association. However, hesaid the dream of an implantable, permanent artificial heart is not yet areality: "This is obviously an experimental device whose long-term successhas to be demonstrated. " Only about half of the 4, 200 Americans on awaiting list for donor hearts receivedthem last year, and most of the rest died:？？
？？ Some doctors, includingRobert Higgins, chairman of cardiology at the Medical Colle？？ge of Virgin-ia in Richmond, said artificial hearts are unlikely to replacedonor hearts.
？？ "A donor heart in a goodtransplant can last 15 t0 30 years, " he said. "It's going to be hardto re-place that with a machine. "
？？ The Abil Cor has a 2-poundpumping unit, and electronic controls that adjust the pumping？？ speed based onthe body's needs. It is powered by a small battery pack worn outside the bodythat transmits current through the skin.
The pump of the first implanted self-contained heart was made of titanium andplastic？？？？？？？？？？？？

In the last century, newtechnology improved the lives of many people in many countries. Howev-er, onecountry resisted these changes. High in the Himalayan mountains of Asia, the kingdom of Bhutan remained separate. Its people andBuddhist (佛教) culture had not been affected for almost a thousand years.Bhutan,however, was a poor country. People died at a young age. Most of its peoplecould not read, and they did not know much about the outside world. Then, in1972, a new ruler named King Jigme Singye Wangchuck decided to helpBhutantobecome modern, but without losing its traditions.
King Wangchuck looked atother countries for ideas. He saw that most countries measured their progressby their Gross National Product (GNP). The GNP measures products and money.When the number of products sold increases people say the country is makingprogress. King Wangchuck had a different idea forBhutan. He wanted to measure hiscountry's progress by people's happiness. If the people's happiness increased,the king could say thatBhutanwas making progress. To decide if people
were happier, he created a measure called Gross National Happiness(GNH).
GNH is based on certainprinciples that create happiness. People are happier if they have healthcare,education, and jobs. They are happier when they live in a healthy, protectedenvironment. They are happier when they can keep their traditional culture andcustoms.-Finally, people are happier when they have a good, stable government.
Now this is some evidence ofincreased GNH inBhutan.People are healthier and are living longer.More people are educated andemployed. Twenty-five percent of the land has become national parks,and thecountry has almost no pollution. The Bhutanese continue to wear ttheirtraditional clothing and follow their ancient Buddhist customs.Bhutanhas alsobecome a democracy. In 2008, King Wangchuck gave hispower to his son. Althoughthe country still had a king, it held its first democratic elections that year.Bhutanhad political parties and political candidates for the first time. Finally,Bhutanhasconnected to the rest of the world through television and internet.
Bhutanis a symbol for socialprogress. Many countries are now interested inBhutan's GNH.These countries areinvestigating their own ways to measure happiness. They want to create newpoli-cies that take care of their people, cultures, and land.
Brazilmay be the next country touse the principles of GNH. Brazilian leaders see the principles of GNH as asource of inspiration.Brazilis a large country with a diverse population. If' happiness works as a measureof progress inBrazil,perhaps the rest of the world will follow.

A.president
