In this paper I have made Hangul text file by hangul word processor and to convert the file into braille I devised Hangul braille code. For further braille code file I presented algorithm that segregates initial phoneme, medial phoneme, and final phoneme from 2-byte Hangul system.

This paper presents the analysis of queueing model to be applied to the development of real-time system on the base of the computer To analyze the perfarmance of queue, we selected the queueing model, M/M/1 (N) which is employed in general and got the analysis result through simulation. This result becomes the important element when developing a real-time system with message queues.

This paper describes a development of the PLD design tool. To design digital circuit with PLDs, several steps in the developed PLD design tool are needed such as Boolean description step, pin map step, FUSE map and JEDEC steps…etc. Especially, we have considered the PLD partition to design large digital circuits with PLDs developed the limited partition algorithms based on the PLD device fitting and compared with the results of a another PLD design tool(PALASM). Also, we have proved that the developed PLD design tool is successfully implemented by the connection with a PLD writer (ALL-07), in the case of design digital circuits.
Graph clustering 알고리즘을 이용한 High-level 라이브러리 맵핑에 관한 연구

In this paper, We propose Graph clustering algorithm uses RT level functional behavior to perform mapping of a Source component onto another Target component of similar complexity, The technique is well-suited for mapping regularly-structured datapath components. We demonstrate the HLLM approach on ALUs components. Our experimental results demonstrate the comprehensiveness and efficacy of the HLLM approach in mapping RT components. We describe the GENUS library environment and a user-interface in the HLLM system for performing RT level design.

It has been studied on the detect and correct of errors occurring in the Process of Keeping and handling of data with the development in data communication field and data base field. Especially, the errors on the process of reception and transmision in data communication field are effective when they are detected and corrected immediately. The writer tried to convert the data using u-processor into Hamming code, and tried to find out the way which can revert the Hamming code to be received to the original data by detecting the presence of the errors and correcting them immediately. The writer concentrated on the drawing up of encoding program and detecting program.
體積 Code에 의한 復數 Bit Error의 檢出과 較正에 관한 硏究

Generally, digital circuit has been designed on the basis that the result by simulated by the arranged tool for plan. In other words, for simulations gate or library sent by IC Cooperation is connected through the schematic editor and the necessary signals for input such as clock signal are supplied. In this way they study the result of simulation. But in this study I found out a new simulation method which is more efficient than the older one in the past. I put a state diagram and state table into tool for design in order to avoid the complexity of circuit input such as combination logic circuit or sequential logic circuit. Then, symbols produced in this way were applied to the schematic editor for simulation.

본 논문은 single user 방식의 minicomputer를 multiuser化 하도록 노력하였다. 특히 BASIC 언어는 punch card의 사용이 곤란한 것으로 생각되기 쉬우나 master console을 이용한 system program의 적절한 운용으로 가능하게 하였으며 file 작업을 통한 punch card의 응용에 대해 기술하였다. This study focused to implement multi-user of mini-computer out of single-user. It enabled the implementation of punch card through application of system program of master console, and described the application of punch card through file works for the BASIC language.

In this study, we have developed the PLD design tool which realizes the digital circuit as PLD,by using EDIF netlist of the digital circuit designed at OrCAD. We propose the alorithms, JIE(Joined Informantion Extractor) which extacts the connecting information between both cells in order to realize the digital circuit as PLD using EDIF netlist,FND(Feedback Node Detector) which searches for whether feedback exists or not ,BEG(Boolean Equation Generator) which generates boolean equation and so on. Also, algorithm generating JEDEC file of GAL 6001 and GAL 6002, has a form of EPLD which is bigger than PLD.

This research analyzes change of Korean language expression factor (speaking speed, frequency character and range of language, sound pressure level) follow time change with experiment. Method of analysis are, to check frequency character with Fast Fourier Transform from digital signal, converted from analog audio signal, and STFT (Short Time Fourier Transform). Sound pressure level is checked in 3 speed steps (slow, normal, fast). As a result, I know that important base frequency is 250Hz and range is 50~2,500Hz. I’ve checked connection change, followed time, between word and syllable. Because sound pressure level change between syllables, component of word, is smooth, this result is helpful information, which analyzes recognition of word.
