Multi-strategies in Case Based Design Knowledge Management on Web

Design knowledge management is very important toimprove the design process performance. The casebased design (CBD) is a methodology to followmankind's problem solving strategy, one of its aims isto realize the design knowledge reuse. This methodhas been used in many fields, but there are still somedifficulties that hindered its application. The first isabout the difficulty in the formalization of a designcase, especially representation of some experiencesthat was the weakness in former researches. The

Antigen presentation by CD1 molecules and the generation of lipid-specific T cell immunity

It is now well demonstrated that the repertoire of T cells includes not only cells that recognize specific MHC-presented peptide antigens, but also cells that recognize specific self and foreign lipid antigens. This T cell recognition of lipid antigens is mediated by a family of conserved MHC class I-like cell surface glycoproteins known as CD1 molecules. These are specialized antigen-presenting molecules that directly bind a wide variety of lipids and present them for T cell recognition at the surface of antigen-presenting cells. Distinct populations of T cells exist that recognize CD1-presented lipids of microbial, environmental or self origin, and these T cells participate in immune responses associated with infectious, neoplastic, autoimmune and allergic diseases. Here we review the current knowledge of the biology of the CD1 system, including the structure, biosynthesis and trafficking of CD1 molecules, the structures of defined lipid antigens and the types of functional responses mediated by T cells specific for CD1-presented lipids.     

本体论概念、方法及其在知识管理中的应用

KNOWLEDGE PROCESS ANALYSIS： FRAMEWORK AND EXPERIENCE

We present a step-by-step approach for constructing a framework for knowledge process analysis （KPA）. We intend to apply this framework to the analysis of own research projects in an exploratory way and elaborate it through the accumulation of case studies. This study is based on a methodology consisting of knowledge process modeling, primitives synthesis, and reflective verification. We describe details of the methodology and present the results of case studies： a novel methodology, a practical work guide, and a tool for KPA; insights for improving future research projects and education; and the integration of existing knowledge creation theories.
