Example of sub prime mortgage loan
House prices 2million won
1 million won my money and bank loans 1million to buy a house
If house prices rise 1million won
Maintain bank loans 1million won
Add of 1million money to 1 million won my money
Currently my money: my money : 2million won –bank loans : 1 million won = 1 million won
If house prices fall 1 million won
Maintain bank loa
1. There is nothing new about man’s need to preserve food for storage or convenience of preparation. Sun-drying, salting, pickling and smoking are methods which have been used for centuries and are still being used today. Recent advances in technology have made it possible to preserve food by decreasing the risk of microbiological spoilage with less loss of taste, texture and nutritive value.
Recently, In April 10 2011, the prime minister of Republic of China, Wen Jiabao, announced that china will continuously implement the tightening measures against inflation and the real estate market which had begun since the April 2010. In respond, China's central bank said it would raise the amount of money that lenders must keep in reserve as official concerns persist over inflation and rising

1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
Heat-Nano Imprint Lithography)
나노 임프린트 리소그래피는 크게 두 가지의 방법이 있는데, 첫째는 열가소성 수지 레지스트에 열을 가해서 패턴을 찍어낸 다음 냉각 시키는 방식을 사용하는 열 나노 임프린트 리소그래피 (Heat-Nano Imprint Lithography)이다. 이는 열 전사, 또는 Hot Empossing공정이라고도 하며 1996

레이저 용접 후 각 시편의 용접 단면의 형상과 용접 금속부 그리고 열영향부(Heataffected zone)의 폭을 관찰하기 위해 용접 시편을 절단하고 시료를 채취해 폴리싱(Polishing) 후 3%-나이탈(Nital) 용액을 사용하여 에칭(Ecthing) 하였다. 용접 단면에서 균열, 기공과 같은 결함을 살펴보고

2)The reason why there is a difference so as to increase heat-treatment time
time Conductivity Resistivity
Such a reason difference
electrical conduction is affected by concentration and mobility
- p-type : mobility more suddenly decrease than the sheep that concentration increases because hall is a major carriers
- n-type : Decreasing
heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.
Skyscrapers put a severe strain on a citys sanitation facilities, to
