1. 서론
1.1. 연구목적 및 방법
■ 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.)
