The Seongdeok Divine Bell(nicknamed "Emile Bell") represents the bell of the Silla dynasty. However, ringing it was stopped since 2003 for the safety of the bell. Currently, Kyungju city is performing a project casting a new great bell(tentatively named "Great Bell of Silla") that inherits the beautiful appearance and the sound of the Seongdeok Divine Bell in order to ring a new coming millenium. The new bell is designed to be almost same as the Seongdeok Divine Bell in terms of size, weight and shape as well as its sound. In this study, we investigate the problems occurring in the design of the bell structure and propose the design strategy for the reconstruction of the traditional large bells.

Silla Great Bell was manufactured in order to ring for the new millennium in succession to King Seongdeok Divine Bell. This study investigates how Silla Great Bell is similar to King Seongdeok Divine Bell in respect of structure and sound. First, design and manufacturing processes are introduced and dimensions of the two bells are compared and the similarity is estimated. Three main characteristics of the sound of a Korean bell are magnificent and harmonic striking sound, dynamic beat, and long lasting hum tone. These three features are compared and objectively estimated using physical parameters. The purpose of the study is to provide useful information to manufacture Korean bell which has beautiful appearance and excellent sound.

National R&D programs are managed and operated by institutes under different ministries. The R&D information created through these programs are designed and constructed heterogeneously both semantically and structurally. Therefore, integrated collection, analysis and application of the information through the interoperability of information at the national level becomes nearly impossible, and redundant production and operation of R&D information becomes a general problem. The Office of Science and Technology Innovation has started the construction of the National Science and Technology Information System(NTIS), which is based on the interoperability and sharing of R&D information, to resolve these issues. In this paper, we propose a method to construct a system for sharing national R&D information held by different ministries while minimizing the effect on the autonomy of the institutes involved.
