Seriousness of Climate Change
Temperatures around the world have increased -> melting glaciers and rising sea levels
Change of habitats, wildlife, cultures, artifacts and the life of humans.
changes in ecosystem, rainfall, desertification. -> flood, drought, typhoons, yellow dust, heat wave

1. Introduction
1-1. Definition of TOD
The way emphasizing land use and the relevance of transportation and inducing the complex land use of public transportation center and walking – riendly transportation system environment. In terms of Urban planning TOD is recognized as techniques that controls extensional reckless city spread and changes traffic-patterns of cars-centric to public t
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
Fatigue Failure Process
균열발생 단계(Crack-Initiation Stage)
공업재료는 연성이며 제조한 상태대로는 균열이 존재하지 않지만, 일반적으로는 입자, 함유물 등을 포함하고 있다고 가정한다. 미시적 크기에서 금속은 균질하지도 않고 등방성도 아니다. 또한 기하학적으로 응력집중(노치)이 되는 부분이 있다
