  • The purpose of this study is to examine the problems of the each cataloging rules about the physical description area that generated the greatest controversy in the cataloging of microcomputer software, and to suggest solutions of these problems. The results of the study can be summarized as follows: 1. Because the physical description area of materials is to identify the physical attributes of the carrier, file description might better described in the material specific details area. 2. Integrated software that related file is linked together need to be used terms that represented any type of software 3. It is desirable that the term 'computer' is to be used as a modifier to devide the carrier of microcomputer and other non book materials. 4. System requirements would better described in a note area rather than physical, description area. 5. It is desirable that other physical details such as recording density, tracks, etc., is to describe in the physical description area, since such information is to represent specifics of the carrier.

  • Recently, multiple criteria decision making has been well established as a practical approach to seek a satisfactory solution to a decision making problem. Goal programming is one of the most powerful MCDM tools with satisfying operational assumptions that reflect the actual decision making process in real-world situations. In this paper we propose an efficient method implemented on a microcomputer for solving linear goal programming problems. It is an iterative revised goal simplex method using the sparsity technique. We design as interactive software package for microcomputers based on this method. From some computational experiences, we can state that the revised iterative goal simplex method using the sparsity technique is the most efficient one for microcomputer for solving goal programming problems.

  • Evoked potentials(EP) measured with scalp electrodes are often described as a deterministic process corrupted by uncorrelated electrical activities occuring in the brain and These electrical activities(ongoing EEG) refer to noise in EP recording. The Conventional method to determine the EP waveform requires long recording time. Unfortunately most of algorithm developed are too complicated for implementation in real time. Thus, conner EP recording devices use Ensemble average for real time processing. In this paper introduce EP recording hardware for processing advanced algorithm in real tlne. This hardware is composed of DSP chip(TMS320c25) and microcomputer.

  • In this paper, the therapy radiation dose measurement system has been implemented by using a microcomputer after radiation was irradiated on diodes from the MM22 microtron accelerator. We have displayed 7-channel diode output values on the LCD after processing those in the 80196 MCU(Micro Computer Unit). Signal processing has been performed in the pulse mode because we can process the signal fast and use it to perform portal image by increasing a number of diode channels in the future. In order to verify the microcomputer based radiation measurement system of diodes, diode output values were compared with that of semiconductor.
