대한항공, 매출 2.5배지만 순손실 9배
대한항공의 순손실 규모가 아시아나항공보다 9배나 컸다. 두 항공사의 외형 차이를 감안하더라도 이같은
Rate of Return on Net sales : Rate of return on net sales is the measure of profitability, and this ratio shows the percentage of each sales dollar earned as net income. Korean Airline’s return(-0.1902) is worse than Asiana’s (-0.0533), but better off than Jeju Air’s (-0.5289).
KAL’s return rate is close to a stunning -20%, and can be considered as being in trouble. But when compare
The 18% discount rate would give an approximation to the correct NPVs for projects with all (or most) of the inflows in the first year.
The present value of $1 to be received one year from now, discounted at 18% is: $0.8475
The present value of $1 × (1 – 0.08) (that is, $0.92) to be received one year from now, discounted at 10% is: $0.8364
The former calculation overstates the correct a
[ What is a Hotel? ]
According to the definition of Wikipedia, a hotel is an establishment that provides paid lodging, usually on a short-term basis. The provision of basic accommodation, in times past, consisting only of a room with a bed, a cupboard, a small table and a washstand has largely been replaced by rooms with modern facilities, including en-suite bathrooms and air conditioning or cli
Introduction
I. Why Airlines?
Profit margins for airlines have always been thin, falling well below the average profitability
of U.S. corporations. Since 2000, margins have been consistently negative. Major air carriers have recorded a surprising loss and have fallen down constantly for the past 7, 8 years. Depressions in the airlines industry were caused by many factors. First, unexpected a

In these modern times, people are always in a hurry.
We like speed, and prefer handling everything quickly.
Everything seems like a race "Who is the most hasty." It's like a competition.
Though our lives have become more comfortable, it is difficult to eat and live well today. Without composure of the mind, we work and study like machines. It seems like we are slaves to velocity. In accordan

the airfoil deflects the oncoming air (for fixed-wing aircraft, a downward force), resulting in a force on the airfoil in the direction opposite to the deflection. This force is known as aerodynamic force and can be resolved into two components: lift and drag. Most foil shapes require a positive angle of attack to generate lift, but cambered airfoils can generate lift at zero angle of attack.
