■ 연구의 목적
자동차 배기가스로 인한 환경오염을 해결하기 위해 무연휘발유를 개발하였다. 무연휘발유는 옥탄가 향상제로 산소계 화합물인 에테르 화합물은 높은 산소 비율로 휘발유 불완전 연소 감소 및 배기가스 중 일산화탄소의 양을 줄여 대기오염의 감소 효
4. Regression analysis
4-1 Tourism destination image depending on PPL effect
We analyzed that PPL give what kind of effect on to Cognitive, Emotional tourism destination image. In other words, we took linear regression analysis to know the Cognitive, Emotional tourism destination image depending on PPL effect. Through the variable calculation, we got the mean of PPL effect. We set this to
indoor environmental score of buildings and occupants' satisfaction, and research about the correlation between criteria and satisfaction. Second, we will compare and analyze between satisfaction of LEED buildings and non LEED building’s, and research effectiveness of LEED certification. As a result, we will suggest development to indoor environment of green office buildings for more human.
the focus of attention by governments and academics
Reduce logistics cost improves technological content and management level.
Reduction of logistics costs by 1% of the GDP means saving of over $7.5 billion!!
Logistics industry has powerful CORRELATIVE EFFECT
(promoting the development of transportation industry, finance industry, information industry, travel industry and so on.)

-Self-realization and personal relations: the stress from these affect one’s health.
-Different amount of exercising and the skill of stress management
-Different amount of relaxation and sleep
3) Put Option Valuation
A Pall Option confers the right on its holder, without the obligation, to sell the underlying asset at a certain date for a certain price. Only a little extra work is needed to value put options. Basically , we just pretend that a put option is a call option and use the Black-Scholes formula to value it. We then use the put-call parity condition to solve for the put valu

correlation endogeneous?
No. The dependent variable (GPA) cannot be responsible for the cause of the independent variable (alcohol consumption). One could argue that a student will indulge in alcohol consumption upon getting good marks on his exam. However, this is not enough to make the relationship endogeneous because the student such an indulgence would last only temporarily rather than being
