Title : SHAGE: Self-managed Software framework for Service Robot
Speaker : Professor Sooyong Park, Ph.D., Department of Computer Science, Sogang University, Seoul, Republic of Korea.
When: January 10, 10AM
Where: Woodward Hall 338 Conference room
Host: Dr. Seok-Won Lee

Abstract
Behavioral, situational and environmental changes in complex software, such as robot software, cannot be completely captured in software design. To handle this dynamism, self-managed software enables its services dynamically adapted to various situations by reconfiguring its software architecture during run-time. We have developed a practical framework, called SHAGE (Self-Healing, Adaptive, and Growing SoftwarE), to support self-managed software for intelligent service robots. The SAHGE framework is composed of six main elements: a situation monitor to identify internal and external conditions of a software system, ontology-based models to describe architecture and components, brokers to find appropriate architectural reconfiguration patterns and components for a situation, a reconfigurator to actually change the architecture based on the selected reconfiguration pattern and components, a decision maker/learner to find the optimal solution of reconfiguring software architecture for a situation, and repositories to effectively manage and share architectural reconfiguration patterns, components, and problem solving strategies. We conducted an experiment of applying the framework to an infotainment robot. The result of the experiment shows the practicality and usefulness of the framework for the intelligent service robots.

Bio: Sooyong Park is an Associate Professor of Computer Science Department at Sogang University. He received his Bachelor of Engineering degree in Computer Science from Sogang University, Seoul, in 1986, the Master of Science degree in Computer Science from the Florida State University, in 1988, and the Ph.D. in Information Technology with major in Software Engineering from George Mason University, in 1995.. During 1996 – 1998, he served as a Senior Software Engineer at TRW ISC. He is actively involved in academic activities such as a Steering Committee Member of Asian-Pacific Software Engineering Conference, Guest-Editor of CACM Dec, 2006 Software Product Line Issue and PC chair of IWFST. In Korea, he is involved various government sponsored committee such as a general secretary of Korean Defense SW Association, Vice-Chair of Korean Information Society Journal, and Chair of Software Engineering Technology Committee. His research interests include, Self-managed software, Dynamic software product-line engineering, and Requirements engineering.

November 10, 2006:
A group of NiSE graduate students participated in the CCI Graduate Studies Open House and presented our on-going research and shared some useful information as a graduate student panel member. This is part of CCI's such effort to look for talented students to pursue graduate studies in computing and we expect to have a bigger version in Jan. 2007.

September 11 - 15, 2006:
Our three research papers have been presented at the SOCCER workshop, MeRE workshop and the Doctoral Symposium at the Requirements Engineering Conference by Robin Gandhi, Lei Liu, Dr. Heather Richter and Dr. Seok-Won Lee. Also Robin did an excellent job as a student volunteer for the RE '06! The pictures were taken at the conference site, Minneapolis/St. Paul, MN.

Graduate Seminar:
Software Assurance: Requirements Engineering Approach
Presented by Dr. Seok-Won Lee and Robin Gandhi
3:00PM on Friday, March 31, 2006, 106 Woodward Hall :
Abstract: In the first part of our talk, we discuss recent efforts from the Department of Homeland Security to create a common body of knowledge for software assurance. We then move on to elaborate on the theoretical backgrounds behind our approach that motivate the need for the definition of a common language in the problem domain to address the issues related to software assurance. In the second part, we discuss our efforts on establishing secure systems assurance based on Certification and Accreditation activities, that include effective ways to understand the enforced organizational security requirements, gather relevant evidences, perceive related risks in the operational environment, and reveal their causal relationships with other domain concepts.

August 29 - September 2, 2005:
Two research papers are presented at the Fourth International Requirements Engineering for High-Assurance Systems Workshop (RHAS’05), and Symposium on Requirements Engineering for Information Security (SREIS) both at the 13th International Requirements Engineering Conference (RE '05), Paris, France.

May 15-21, 2005:
A research paper is presented at the Software Engineering for Secure Systems (SESS '05) Workshop, the 27th International Conference on Software Engineering (ICSE '05) St. Louis, Missouri, USA.
