. Summary:
1. Industry overview-- current situation of Korea pizza market
Korea pizza market with Big 3 brands as its center, an intense competition with large numbers of unique and new product was appeared, so that expand the size of Korea pizza industry and ushered in the mature period with 1 trillion won in 2006 .
During the past four decades Pizza Hut has built a reputation for excellence
3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
가-2. DIMM
현재 인텔 펜티엄이나 모토로라의 파워PC 등과 같은 프로세서에서 64비트 데이터 버스에 알맞게 사용하기 위해서는 72핀 SIMM을 쌍으로 인스톨해야 하며, 이로 인해 모듈이 차지하는 크기가 커졌다. 그러나 소수의 컴퓨터만이 대용량 메모리 모듈을 지원할 수 있었기 때문에 물리적인 크기의 변
A. Localization strategy: Success and failure of foreign store operation is determined by how closely it could approach to their culture and language. Focused the point that Chinese E-Mart Shanghai store is right Chinese enterprise and it’s not others because it is different from theirs.
Being tried to change the naming of the job title which co-workers could see each other in the viewpoint o
Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
1.2 Structure of Planning for Security
Clearly, the subject of security has wide implications that reach far beyond the jurisdictional limits of the airport to central government itself. Planning to meet the needs of a security emergency requires the involvement of a number of organizations, such as:
∎ The airport administration
∎ The operation airlines
∎ The National
2. 제프콧 로터 시스템
제프콧 로터 시스템은 회전체 역학에 사용되는 모델 중에서 가장 단순한 모델이다. 이것을 도시하면 다음 그림과 같다.

1. 임펄스 테스트
FEM 이나 전달 행렬 방법으로 모델링 한 회전축을 실험적으로 검증하기 위해서 임펄스 테스트를 수행한다. 베어링이 없는 축을 매달고 매단 방향과 직각으로 가속도계를 축에 붙이고 축을 임팩트 해머로 때려 그 둘 사이의 주파수 응답을 구한다. 이러한 주파수 응답을 통해서 회전축
