The multimedia documents becomes the most natural user interface for CSCW(Conputer Supported Cooperative Work) in distributed environment. The objective of this study is to propose a multimedia document architecture and to develop a system that can manage it well. The new architecture is for revisable documents and is the basic layer for hypermedia documents. A good document architecture for CSCW must support pointing, marking, and editing over a part of documents. The user views, version control, and full- content search are also desirable features. In this paper, we discuss the basic concept of a new document architecture for CSCW. We also present the user interfaces for spatio-temporal compositions of multimedia documents.

This paper presents a parallel implementation of stiff-ness matrix calculation based on the processor farm model on a net-work of workstations running PVM programming environment. As the computational characteristics of stiffnes matrix exhibits good po-tentials for effective prallel computation the performance improve-ment is show to be almost linear with the number of sorkstations involved in the computation.

Base isolation is the alternative tool to protect structures against the earthquake. Basic ideas are the flexibflity to reduce the response of the structure, energy dissipation to reduce the excessive deflection by flexibility, and the rigidity under the service load. Base isolation is specially good for bridges because it can be installed easily and be used for both new construction and rehabilitation. This paper describes the basic ideas of base isolation, various base isolation devices and design guidelines by AASHTO. It also introduces the applications in United States and New Zealand.

A complete design of a new digital control circuit for a three-phase controlled rectifier is presented. The circuit consists of a gating signal generating ROM, down counter and adder. Proposed scheme is simple and quite adequate to the microprocessor-based digitally controlled systems. The basic principle and operation characteristics of the circuit are described and experimental-results show good dynamic performance. Synchronization problem with noisy reference is also discussed. The basic phylosophy developed can be extended to the other phase control system, e.g., cycloconverters, ac voltoge controllers, etc.

DCT or Wavelet based on Image compression technique occurred to compression artifact. In order to remove this problem, we can apply many improvement algorithms. But in these cases, these algolithms resulted in bad results against the good quality image. Therefore this paper proposes an automatic image interpretation technique not to apply to the good quality images. In this paper, we exploit the basic nature of DCT.

Some basic guidelines for changing non-uniform boundary condition in an acoustically small cavity are presented. In this paper, modal summation technique is used to represent inside sound field. From this formulation, corner effect is defined and proposed. The corner in a cavity is good position for changing boundary condition effectively. Impedance circle with same absorption coefficient is defined to find appropriate impedance of absorptive material for better noise control performance.

In this paper we study the Minimum Error Discrimination problem (MED) for ensembles of linearly independent (LI) pure states. By constructing a map from the set on those ensembles we show that the Pretty Good Measurement (PGM) and the optimal measurement for the MED are related by the map.

In this paper, We study several method of CTQ measurement for improvement of Quality. Measurement are cornerstone of basic improvement of Science and Technology and are considered continuous thesis. In this paper, we survey measure several variable for CTQ for Six sigma. We introduce Taguchi's SN ration Which is important example good measure for improve quality Improvement are succeed by good select measure variable which is called CTQ which should agree problem define and final goal.

A summary of the main results from an international comparative study for the high-frequency base balance is given. Two buildings were specified - a 'basic' and an 'advanced' building. The latter had more complex dynamic response with coupled modes of vibration. The predicted base moments generally showed good agreement amongst the participating groups, but less good agreement was found for the roof accelerations which are dominated by the resonant response, and subject to measurement errors for the generalized force spectra, to varying mode shape correction techniques, and different methods used for combining acceleration components.

Recently, medical humanities education has begun to take up an increased proportion of the Korean medical curriculum. Many people now agree that not only basic medicine and clinical medicine but also medical humanities is needed in medical education. The aims of medical humanities education should dawn now. 'Medical humanities' can be roughly defined as "the interdisciplinary study and activity at the intersection of the humanities, social science, arts, and medicine." People tend to assume that the aim of medical humanities education is to produce good doctors, that is, physicians who contribute to society. Actually, cultivating good doctors is one of the proper aims of medical humanities education. In addition to it, another aim of medical humanities education should be cultivating happy doctors. Nowadays, many of Korea's physicians feel unhappy. In such a situation, medical humanities education should be aimed at developing happiness in medical trainees.
