  • A data allocation technique is essential to improve the performance of data broadcast systems. This paper explores the issues for allocating data items on broadcast channels to process multiple-data queries in the environment where query profiles and query request rates are given, and proposes a new data allocation scheme named IDAS. The proposed scheme employs the strategy that the broadcast frequency of each data is determined by the square root value of its relative access probability. IDAS could enhance the performance of query response time since it can process queries of high request rate fast and show a resonable degree of query data adjacency. Simulation is performed to evaluate the performance of the proposed scheme. The simulation results show that IDAS outperforms other schemes in terms of the average response time.

  • The purpose of this study is to suggest a foundational design direction for seniors, according to paradigm shift in aging society. This paper researched on current state of the aging society through literature study and defined the theoretical concept that set the foundation of the study. Secondly, for building an age-friendly city, relevant studies on seven cities were selected and their regional design guidelines were analyzed. As a result, essential design elements for building the aging-friendly city were defined as safety, recognition, and accessibility. A detailed design guideline that applies the three elements with understanding on seniors is required to construct the environment for a senior-friendly city. Ultimately, the result of this study is expected to be in practical use as a fundamental resource for age-friendly city design.
