This paper proposes a new approach to collaboratively designing original products and crafted objects in a distributed virtual environment. Special attention is paid to concept formulation and image substantiation in the early design stage. A data management strategy and its implementation method are shown to effectively share and visualize a series of shape-forming and modeling operations performed by experts on a network. A 3D object representation technique is devised to manage frequently updated geometrical information by exchanging only a small amount of data among participating systems. Additionally, we contrive a method for offloading some expensive functions usually performed on a server such as multi-resolution data management and adaptive data transmission control. Client systems are delegated to execute these functions and achieve "interactivity vs. image quality" tradeoffs based on available resources and operations in a flexible and parallel fashion.

An enormous amount of log data is generated by servers and other devices on the network, and server/network administrators analyze the logs to investigate anomalous communications or troubleshoot. However, server/network management tasks increase in volume and complexity, resulting in greater burden on the administrator. In this paper, we propose an integrated management system for a sensor network where log data is output from many different kinds of sensors. We consider a server or network device as one of the sensors. We also propose a cross-processing system for several kinds of log data. In particular, we describe the management and collection of logs in our campus networks.
