작업자가 작업장에서 전도 등으로 인한 산업 재해를 입지 않도록 하기 위해서는 작업장에서의 전도 상황을 판단하여야 하며, 이러한 전도 상황을 측정할 때 자동화된 전도 측정 장치는 작업장에서의 효율성을 확보하는 동시에, 전도를 측정하는 사람이 측정 과정예서 일어날 수 있는 불상사 등을 예방하여 산업재해를 미연에 방지해서 이를 통한 산업 현장의 안정성 확보를 통한 부대 비용 발생을 방지할 수 있게 된다. 이러한 자동화된 전도 측정을 위한 방편으로써 전도 측정용 로봇의 개발하였다.

Because buildings which apply color that is various to concrete recently are introduced, value as design element of building is rising gradually in townscape. Even if expense is increased according as importance of concrete that have variety of design because do such social background and connection is emphasized, development of color concrete is pressing. Therefore, in this research, examined concrete physical & chemical characteristics by use of acid agent as part of research to embody diverse surface color of cement material. Here, embodiment of various color by unique color that stained hydrate has as that Color Concrete forms stained oxide that react with hydrate within concrete spreading stained agent that contain acid and metallic-ion in matrix that have cement ingredient on the surface is available.

Simulation has been recognized as one of major application areas of world wide web. Over the last several years, most research has been focused on the development of web-based simulation languages mostly using JAVA and validation of simulation modeling on web with the newly developed languages. In this paper, we develop a tentative web-based simulator for a simple unit-load automated warehouse system, named Web-SAW. In constructing Web-SAW, we program a user interface program, a simulation logic program, and an animation program with JAVA while utilizing the class library functions and embodiment environment of existing web-based simulation languages. Web-SAW simulates the automated warehouse system with the user input about system operation, displays the animation on a static background representing the system, and generates the various textual outputs after simulation.

The automatic firewall block and fire alarm system was embodied by using gas circuit and wireless communication equipment, using a smoke sensor (ST-QA1A) and RF Module. OR-CAD was also used for testing circuit system and experiment circuit after assembling circuit. As a result in experiment, the gas sensor detected well an imaginary smoke and worked reliably for driving action of firewall block motor and wireless warning alarm. Through the smoke sensitive perception from the fire, the warning alarm and the preventing fire propagation from the specific closed region were verified reliably. The gas sensor and RF module for firewall and fire alarm system were actually available.

There are two reasons that the remote medical is newly embossed. One is the development of the info-communications technology that is possible to the remote diagnosis. Another is changing the thinking about the new medical services for the offerers and consumers. Therefore, we suggest the WPKI mobile-environmental remote diagnosis system. The system could apply more efficient connetion with the very fast developing diagnosis and medical treatment.

XML is standard of web document, and is used in language for document data exchange. XML document is used as example that change existing document to XML or makes new document by XML increases and XML search system to search XML document efficiently accordingly is requiring. This paper describes design and implementation of query processing system for translating XML elements and data between XML documents and relational database and consist of XML to DB processor, DB to XML processor and XML document management processor. Through this, described for design and embodiment of efficient XML document search system of JAVA base using XQL that is proposed in language of quality of XML document.

다중 채널 광학 정렬 시스템에서 가장 중요한 문제는 각 채널별 정렬이 얼마나 정밀하게 이루어지며 향후 패널의 다중화가 어느 선까지 가능할 수 있는가이다. 기존 시스템은 채널 양쪽에 검출기를 설치하여 광량의 최대 지점을 정렬 위치로 결정하는 방식을 사용했다. 그러나 시스템 채널이 증가함에 따라 정밀한 정렬과 만족할 만한 성능을 얻기에는 어느 정도 한계가 있음을 알 수 있었다. 이러한 단점을 보완하기 위해 본 논문은 단일 검출기를 사용하여 패널별 광량을 측정할 수 있는 방법을 제안한다. 그리고 복원 알고리즘을 통해 기존의 시스템과 다른 측정법과 만족할 만한 결과를 도출하는 방법을 소개하고자 한다.
