People are increasingly looking for health-related information and support to empower their sel f-management and decision making. Online health communities have not only become an important alternative source of patientcentered information but also appear to serve an emotional support role in connecting patients who have similar medical conditions. Trust is critical to sustain their continuous use and enhance their involvement. This is because each community member is typically identified onl y by a pseudonym, important personal information is often revealed, the quality of information provided by others varies, and the consequences of acting on incorrec t advice can be severe. Using semi-structured interviews and data from postings, thi s study qualitatively explores the trust development betw een users of forum-based online health communities. Based on data from a w ide range of medical conditions, we formulated a three-process framew ork for establishing trust that conceptualizes how users build trust through the text-based medium and how they progress from one process to another. We contribute to theory by extending exi sting variance theories in trust to a hybrid process theory whi ch explains the dynamic progression from one state to another. It suggests several design foci that can enhance user experience of these forums.

In this paper we first discuss the framework and basic organization structure for collaborative commerce (c-commerce) by employing object-oriented methodologies in commercial intelligence aspect. Then we design the function and structure for Cooperative Center Process Unit (CCPU). Finally, we examine the strategic role of knowledge management for ccommerce as well as managerial and business implications by citing the interaction in auto c-commerce as an example.
