본 연구과제는 건설업체의 현재 문제점은 각 업체별로 상이한 분류 및 식별코드체계를 사용, 품목표기방식, 속성 포맷의 불일치, 용어와 단위의 불일치, 현 업계에서 사용하는 코드 분류체계는 호환이 되지 않고 국제적으로 사용할 수 없는 부적합한 실정이다. 따라 기존의 통합정보시스템과 별개로 관리 운영이 이원화되어 오던 각종 건설정보를 건설CALS/EC 핵심기술을 적용하며 건설표준 ERP 템플릿시스템을 개발 할 목적으로 한다. 따라서 본 연구에서는 건설표준 ERP 템플릿시스템과 건설통합분류체계의 표준코드의 연계로 건설CALS/EC 핵심기술이 적용된 건설표준ERP(통합DB)를 구축과 건설공사의 물량산출 데이터의 체계화된 물량예측과 물량공정의 통합화와 설계정보, 시공정보 및 관리유지정보의 연계하여 그리고 현장관리 및 원가관리정보의 통신망접속으로 건설통합정보를 제공한다.

In this paper we discussed a new methodology for Urdu Character Recognition system using Dempster-Shafer theory which can powerfully estimate the similarity ratings between a recognized character and sampling characters in the character database. Recognition of character is done by five probability calculation methods such as (similarity, hamming, linear correlation, cross-correlation, nearest neighbor) with Dempster-Shafer theory of belief functions. The main objective of this paper is to Recognition of Urdu letters and numerals through five similarity and dissimilarity algorithms to find the similarity between the given image and the standard template in the character recognition system. In this paper we develop a method to combine the results of the different distance measurement methods using the Dempster-Shafer theory. This idea enables us to obtain a single precision result. It was observed that the combination of these results ultimately enhanced the success rate.

There are some problems on the system that uses a password comprising a digital signature to identify the secret key owner under the public key infrastructure. For example, the password can be difficult to remember or easy to be disclosure, and users should make more complex password to protect it. A number of studies have been proceeded in order to overcome these defects using the fingerprint identification technologies, but they need to change the current standard of public key infrastructure. On the suggested private key escrow system, the private key can be withdrawn only through the enrollment and identification of a fingerprint template after it is saved to a reliable third system. Therefore, this new private key escrow system can remove previous inconveniences of managingthe private key on current public key infrastructure, and it exhibited superior results in terms of the evaluation items when compared with the integrated method of the existing fingerprint identification and public key infrastructure.

Life cycle costing is one of the most effective approaches for the cost analysis of long-term life products, like as railroad vehicle. Life cycle costing includes the cost of concept design, development, manufacture, operating, maintenance and disposal. Especially, life cycle costing in the railroad industry has been focused on the maintenance cost. In this paper, we investigated the standard, guide and maintenance information of railroad vehicle. For this purpose, we suggested the unique templates of railroad vehicle maintenance information. We also performed maintenance cost analysis on the some sub-system of railroad vehicle for the case study.

본 논문은 XSD(XML Schema Definition)기반의 XML 문서를 웹, 엑셀 환경에서 다양한 관점으로 볼 수 있도록 템플릿 서비스를 제공하기 위한 시스템이다. 템플릿 서비스는 데이터스킨 서버에서 스킨을 통하여 서비스되며, XML 문서를 다양한 문서로 변환할 수 있도록 한다. 예로 XML 문서를 HTML로 변경하는 경우 XSLT(Extensible Style Language Transformation) 를 사용할 수 있고, 엑셀 문서로 변환할 경우 엑셀 템플릿을 만들어 스킨으로 제공할 수 있다. 스킨은 다양한 방법으로 구현될 수 있으며, XML 문서에서 사용자가 원하는 문서로 만들기 위한 미들웨어 역할을 한다. 사용자는 데이터스킨 변환 서버에 접속하여 가지고 있는 XML 정보들을 차트, 그래프, 수식 등으로 쉽게 변환할 수 있을 뿐만 아니라 OWC(Office Web Component)로 쉽고 빠르게 문서를 변환 할 수 있도록 한다.

A geometric kernel is the library of core mathematical functions that defines and stores 3D shapes in response to users'commands. We developed a light geometric kernel suitable to develop CAD/CAM application systems. The kernel contains geometric objects, such as points, curves and surfaces and a minimal set of functions for each type but does not contain lots of modeling and handling functions that are useful to create and maintain complex shapes from an idea sketch. The kernel was developed on MS-Windows NT using C++ with STL(Standard Template Library) but it is compatible with UNIX environments. This paper describes the structure of the kernel including several components: base, math, point sequence curve, geometry, translators. The base kernel gives portability to applications and the math kernel contains basic arithmetic and their classes, such as vector and matrix. The geometry kernel contains points, parametric curves, and parametric surfaces. A neutral fie format and programming and document styles are also presented in this paper.

Salmonella enteritidis is the most prevalent etiologic agents of foodborne acute gastroenteritis. Direct isolation and identification of S enteritidis are time consuming work and not so highly sensitive. This study was conducted to develop for the specific detection of S enteritidis using polymerase chain reaction(PCR). PCR primers were selected to amplify a 351-base pair(bp) DNA fragment from the salmonella plasmid virulence A(spv A) gene of S enteritidis. With the primers, 351 bp DNA products were amplified from S enteritidis but not from other B, D, Cl serogroup Salmonella spp. It was sensitive to detect up to 40 pg of template DNA by agarose gel electrophoresis. This PCR assay is very rapid and specific method and less time consuming than the standard bacteriological methods.

Recent explosive increases in information 'volume have led to a rapid development or a change of information technology which stores, searches, and manages a vast amount of information. It is considered that an effective share and utilization of a large amount of digital information produced by work performances is a pivotal element which can make decisive contributions to a great success of business management. This common property of information reflects a changing social paradigm including a change of business processes. This paper is aimed at designing and embodying the construction of knowledge base in an efficient project management system using unsupervised data mining techniques in order to extract information and utilize it as knowledge about standard data (statistical data, template etc.,), size prediction and a danger precaution notice which are needed for a plan and a scheduling of a new project from data coming from already-established projects.

A neuro-fuzzy based circuit to recognize circuit pat-terns is proposed in this paper. The simple algorithm and exemption from the use of template patterns as well as multipliers enable the proposed circuit to implement on the hardware of an economical scale. Furthermore, thanks to the circuit design by using current-mode techniques, the proposed circuit call achieve easy extendability of tile circuit and efficient pattern recognition with high-speed. The validity of the proposed algorithm and tile circuit design is confirmed by computer simulations. The proposed pattern recognition circuit is integrable by a standard CMOS technology.
