III.          Profile of Institution

Sungkyunkwan University (SKKU) was established 600 years ago on the current site as the first institute of higher learning in Korea. The history of higher education in Korea can be traced back to Taehak, which was founded in Kokuryo in 372 A.D. It was, however, in 1398 that King Taejo in Chosun Kingdom founded Sungkyunkwan (SKK), the predecessor of SKKU, and equipped it with all the necessary facilities to be considered a university: headquarters, lecture halls, libraries, dormitories and temples, among many others. For over 500 years from its foundation, SKK had been the cradle of most of the distinguished scholars and statemen in Chosun Kingdom. As the highest of national institutes, SKK was susceptible to political changes throughout its history. Its forced degradation during the Japanese occupation was SKKU's darkest period.

Shortly after the liberation of Korea, SKKU embarked on a massive program to regain its suspended glory, building the University's modern campus on the site of SKK. SKKU is now made up of 13 colleges, 10 graduate schools, 30 research institutes and 2 affiliated educational facilities. It now has 20,000 full-time students. Since 1978, the University's new, modern Natural Sciences Campus located in Suwon has been operational. This Natural Sciences Campus offers a wide range of facilities with educational and research equipment for undergraduate and graduate students in the Colleges of Sciences, Engineering, Life Science and Natural Resources, Pharmacy, and Medicine.

The Safety and Structural Integrity Research Center (SAFE) was established in June, 1997 at Sungkyunkwan University (SKKU), Suwon, Korea as an Engineering Research Center (ERC) designated by the Korea Science and Engineering Foundation (KOSEF). In modern society we rely more on advanced technology-intensive industrial facilities such as nuclear and fossil power plants, heavy and petrochemical industries, and pipelines. These high performance facilities serve as the fundamental base of modern society.  Advanced technology, on the other hand, is a major source of threats to the safety of the global society. In fact, the world has recently experienced catastrophic failures of industrial facilities which have brought a great amount of losses in life and money. Korea has not been an exception. Thus, currently in the global society there is very strong need for the development of advanced technologies that can evaluate the safety of industrial facilities very accurately. In deed, SAFE was born to address such public concern with the very close cooperation among various institutes including not only KOSEF and SKKU but also more than 30 industries and 12 universities in Korea.

SAFE has defined the four key technologies of safety evaluation; safety diagnosis (nondestructive evaluation), material degradation, structural analysis and fracture mechanics, and is carrying out research on each field by inviting highly reputable scholars from other nations around the world. In addition, SAFE is also performing various activities including the followings; cooperation with industry for the application of newly developed techniques in practice, international collaboration with worldwide leading institutions for performing cooperative researches, and education and training engineers.


NDE ACTIVITIES

 

1.    Principal Mission of NDE Activities

SAFE has four major objectives:

*     Research and development of the advanced NDE technology for safety diagnosis systems for industrial facilities such as nuclear and fossil power plants, heavy and petrochemical industries, and pipelines

*     Education and training of qualified NDE engineers

*     Establishment of a major, national focal point for advanced NDE technology transfer to industry

*      International collaboration of advanced NDE technology

2.    Technological Environment

SAFE serves organizations at the regional, national and international level. The core of the research support is from the Korea Science and Engineering Foundation (KOSEF) and various institutions including, for examples, Korea Institute of Machinery and Metals, Korea Research Institute of Standards and Sciences, Korea Atomic Energy Research Institute, and Korea Institute for Nuclear Safety. Also more than thirty companies and institutes in Korea are participating in consortia of SAFE on safety evaluation of industrial facilities.

3.    Departments/Centers Involved in NDE

The work of SAFE is conducted by a mix of faculty, students, and full-time professional scientists and engineers. Since SAFE is a national-wide research center designated by KOSEF, SAFE is able to draw faculty and students from any university in Korea. Current principal investigators who participate in the NDE area of SAFE are invited from several universities such as Sungkyunkwan University, Yonsei University and Inha University. Faculty and student can involve, in part, in SAFE by the project base, too. Academic departments from which faculty and students participate SAFE include Mechanical Engineering, Civil Engineering, Electrical and Computer Engineering, and Materials Science and Engineering.
