To take maximum advantage of computers without compromising the health of library staffs and users, it is important that the computer workstation be adapted to the needs of the users. While the topic of occupational safety and health is a major industry concern, it is not commonplace in libraries. Therefore, this study is to apply the ergonomic principles to library computer workstations and suggest the ergonomic models for computer table and chair, monitor and keyboard placement, posture and motion. lighting, and other environments.

A bilingual sound dictionary in Korean and English has been created for a broad range of sound reference to cross-linguistic, dialectal, native language (L1)-transferred biological and allophonic variations. The paper demonstrates that the pronunciation dictionary of the lexicon is inadequate for sound reference due to the preponderance of unmarked sounds. The audio registry consists of the three-way comparison of 1) English speech from native English speakers, 2) Korean speech from Korean speakers, and 3) English speech from Korean speakers. Several sub-dictionaries have been created as the foundation research for independent development. They are 1) a pronunciation dictionary of the Korean lexicon in a keyboard-compatible phonetic transcription, 2) a sound dictionary of L1-interfered language, and 3) an audible dictionary of Korean sounds. The dictionary was designed to facilitate the exchange of the speech signal and its corresponding text data on various media particularly on CD-ROM. The methodology and findings of the construction are discussed.

NUI is a motion interface. It uses the body of the user without the use of HID device such as a mouse and keyboard to control the device. In this paper, we use a Pi Camera and sensors connected to it with small embedded board Raspberry Pi. We are using the OpenCV algorithms optimized for image recognition and computer vision compared with traditional HID equipment and to implement a more human-friendly and intuitive interface NUI devices. comparison operation detects motion, it proposed a more advanced motion sensors and recognition systems fused connected to the Raspberry Pi.

컴퓨터의 주변 장치 중 하나인 마우스는 모니터의 2차원 평면에서 움직임을 인식하여 커서를 움직이는 입력 장치이며, 응용 프로그램을 편리하게 사용하고 다양한 편집을 가능하게 한다. 기존의 아이디/비밀번호 기반 인증 방법에서는 키보드 데이터가 노출되는 취약점이 존재하여 이미지 기반의 마우스 입력을 이용한 새로운 인증 방법이 등장하였지만, 이미지 기반 인증의 취약점 분석 및 실증에 대한 연구는 미비한 실정이다. 따라서 본 논문에서는 마이크로소프트 운영체제에서 제공하는 마우스 위치 추출 API인 GetCursorPos() 함수를 이용하여 마우스 데이터의 노출 가능성을 검증함으로써 취약점을 분석한다.

In this paper, we present the theory of computers and mathematics education based on the concept of microworlds for mathematics education. We lust look back some previous papers published in the journal of the Korea society of mathematical education series A and else where. Then we present the new view points regarding mircroworlds and mathematics curriculems, microworlds and mathematics teaching and teaming, microworld based problem centered teaming, and microworld based diagnostics and debuggings. We use JavaMAL microworld that is designed to make LOGO and dynamic geometry system in one microworld to give some examples to explain the necessary mathematics educational needs fur designing microworlds for mathematics education. The JavaMAL microworld is a web based microworld that is programmed using JAVA, and the user on use script language, menus, keyboard, and mouse interaction to use the environment.

In this paper, we proposed a speech support system of personal computer for the blind. The system is consist of hardware part and software part. The hardware part are consist of personal computer and sound card. The software part are consist of sound driver system, character table and sound output algorithm. This system can recognize inputted characters from keyboard and program produced character strings.

This paper presents the simulation environment that verifies whether a new microprocessor described with HDL is compatible with MS-DOS. The phrase 'compatible with MS-DOS' means that the microprocessor can execute MS-DOS without any modification of MS-DOS's binary code. The proposed verification environment consists of HDL simulator and user interface module. And the communications between them are performed by using sockets which UNIXprovide. The HDL simulator is equipped with several functions, which use PLI to emulate ROM-BIOS facilities. The ROM-BIOS emulation routine is described by using these functions. User interface module utilizes S/MOTIF and participates in emulating PC monitor and keyboard. The verification environment is tested by executing the MS-DOS commands (DIR, FORMAT, DATE, TIME etc.) with the HDL model of microprocessor, and the display of user interface module verifies that the environment works correctly. In this paper, the method of constructing the verification environment is presented, and the simulation results are summarized.

In this paper, an improved on-line neural network model is suggested. This neural network is designed to store and recall sequence of key strokes in on-line. The network stores incoming patterns as weight connections between series of layers. The layer has a 2-dimensionally distributed neurons where the location of neurons are relevant to the actual location of computer keyboard. To store longer patterns, the network has circulating layer connections and different patterns can be superposed on the same layer. Also, when the patterns are stored over the layers, the starting layer is not fixed but changed by the characteristics of Patterns to increases network capability. The ways how to choose the starting layer during the store and recall process are investigated.

본 논문은 신경망과 퍼지 이론을 결합한 한국어 철자 교정기 KSCNN(Korean Spelling Corrector using Neural Network)에 대하여 기술한다. KSCNN은 퍼셉트론(perceptron) 학습을 이용한 연상 메모리(associative memory)로 구성되며 자판 배열 특성을 고려한 퍼지 멤버쉽 함수에 의해 신경망의 입력값을 정한다. 본 철자 교정기의 장점은 인지적인 방법으로 철자를 교정하기 때문에 기존의 VA나 BNA와는 달리 오류의 종류에 영향을 받지 않으며 교정된 철자나 후보자들에 대한 견인값(attraction value)을 측정하여 시스템의 신뢰도를 높일 수 있다는 데 있다. 또한, 본 논문은 실험을 통해서 퍼지 멤버쉽 함수에 의한 입력 노드의 활성화가 자판 배열특성을 고려할 수 있기 때문에 시스템의 성능을 향상시킨다는 사실을 보여준다.

중국어(한어)를 라틴 알파벳으로 전사하는 음운표기 체계를 병음(Pinyin)이라고 하는데, 이에 비해 한국어 사용자를 위한 한글식의 중국어 전사 표기가 여러 가지가 연구되었다. 이는 한국어 및 한글 구사자에게 중국어를 학습하거나 중국문자를 컴퓨터에 입력하는 데 유용할 것이다. 이 논문은 중국어 한글전사 표준과 이 용도의 키보드를 만드는 원칙을 연구한 것이다. 핵심은 중국어의 한글전사를 현대 한국어맞춤법을 따르도록 하고, 기존 표준키보드에 정합되게 한다.
