The Wellcome Trust, the dindependent medical research charity, has sponsored this research in order to explore the value assigned to the teaching of socio-scientific issues, specifically those arising from biomedicine, in secondary and post-16 education. Today's young people will be the first to benefit from developments arising from, for example, the Human Genome Project and stem cell technology, but they will also be the first to face the challenging social and ethical questions these technologies raise.

심포지움 개요 : VLFM 2001은 2001. 9. 5 ~ 2001. 9. 7의 기간동안, Italy의 Stresa에서, 100여명의 시각언어 전문가와 정형 기법 전문가들이 참석한 가운데 치뤄졌다. 이번 심포지엄에서 확인할 수 있었던 가장 큰 연구 동향은 시각언어, 정형기법 연구의 흐름은 UML과 정형기법의 결합이라고 할 수 있다. Unified Modeling Language (UML)은 객체지향 시스템 개발을 지원하기 위한 시각적 언어들의 집합으로써, Object Management Group(OMG)에 의해 국제표준이 되었다. UML의 정형적 의미 정의 및 이에 기반한 소프트웨어 개발 방법론, UML과 XML등의 연계 등은 현재 소프트웨어 공학의 중요한 연구 분야로 떠오르고 있으며, 이번 VLFM01에서도 이러한 추세를 확인할 수 있었다. 이번 VLFM’01에서도UML과 UML의 주요 부분인 Sequence Diagram 및 sequence diagram의 모태인 Message Sequence Chart, 또는 Statechart를 다루는 연구가 주로 발표되었다. 이외에도 전통적인 그래프에 기반한 시각 언어기법, 프로그래밍 언어에 기반한 시각 언어에 대한 접근, 논리술어에 기반한 시각 언어 접근 등이 발표되었다. 심포지엄은 5개의 session으로 구성되었다. - Statecharts, H-Graphs and Graph Transformation - Specification of Visual Languages and Tools - Languages Visualization & Diagrammatic Reasoning - Defining the Semantics of UML & Extending MSC - Combining UML and Formal languages 이 심포지움의 보고서는 KAIST에 계신 윤광식님께서 수고해 주셨습니다. 궁금하신 점은 윤광식님께 문의하시기 바랍니다 e-mail : gsyoon@salmosa.kaist.ac.kr 첨부 .Visual Languages and Formal Methods - gsyoon.pdf
