In a cluster system where nodes are connected via high-speed networks, accessing data in remote memory could take less time than accessing data in a local disk. As the price of DRAM gets cheaper, it becomes more attractive to use idle memory in a remote node to store data for future accesses. Network memory has been studied to use the idle remote memory for paging space or buffer caches, and it has been shown that network memory could improve the overall system perfoiinance by reducing the number of accesses to relatively slow local disks. In previous studies, operating system kernels or user-level libraries were modified to use network memory. However, these approaches requires either the modification of the kernels or user applications. In this paper, we propose using operating system expandibility features, such as loadable modules in LINUX, and a block device driver wrapper which accesses remote memory for data instead of accessing local disks. Our scheme does not need kernel modifications or user application changes. We present the design and implementation of the block device driver wrapper in detail in this paper.

This study proposes a methodological framework for extending the KOSDIC format, which has been developed as a standard for construction drawing file exchange. The Ministry of Construction and Transportation, in cooperation with the KICT(Korea Institute of Construction Technology), has recently finished the development of the KOSDIC 1.0, and is now seeking for strategic application scenarios in order to disseminate the KOSDIC format throughout the field works as well as the government institutes. The basic idea is that the KOSDIC format may not be well accepted in favor of legacy CAD systems unless otherwise clear benefits are experienced. Thus, we need first to define the next levels of KOSDIC development based on technical requirement and advances, second, to provide a progressive operation framework which extends the KOSDIC functionalities. Through the investigation of similar research efforts and by applying recent advances in Information Technology area, the authors have formulated futuristic application scenarios of KOSDIC format. Among the suggested methods, this paper presents the proposal of KOSDIC-XML. The KOSDIC-XML is an XML based application framework which extends the KOSDIC format by integrating various web technologies. They include channel based XML technology, Webservice framework, and distributed computing. The result of the research will be used for a theoretical framework KOSDIC-XML schema and its prorotype applications at the next phase of this research.

In this paper, the scattered electric fields is computed to predict the shielding zone by analysing the effect of the reflected azimuth anlge at the building, and considering the path differences at observation point between the rays from origin and any point in the building. The scattering coefficients, which are applicable to the prediction of shielding zone, are computed and compared with measured one. We found that the scattering power become weak over 10 degree of the azimuth angle at which the scattering coefficient is lower than 40 dB. From this. the shielding zone can be estimated.
