Answer to Question 1

The problem that is to be solved does not exist in a vacuum, but in a context called the problem domain. Medicine provides a ready example. To a patient, a headache is a problem, but the doctor must treat it as a symptom of the real problem. The doctor would be very negligent to prescribe aspirin for every headache, regardless of whether the root cause is listening to loud music or something less benign or even life-threatening. In building a solution, we also create a new and distinct context called the solution domain. This context contains elements that can be unrelated to the problem but are needed to support the purpose and the functionality of the solution: most cars have fans to cool down the engine, even though the heat produced by the engine has no connection to the transportation for which the car is built. (Similarly, the fans in computers are not related to computing.)

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.
