Telematics, one of the so-called New Growth Engine of IT839, is a leading IT service where wireless internet service represented by information and mobility is extended to the area of transportation. To provide telematics service, Telematics service provider have to connect with various Contents Provider or Service Provide server - for example - LBSS(Location Based Service Server), ASPS(Application Service Provider Server), TELICS(TELematics Information Center Server), GMS(Geo-mobility Server), WTPS(World Telematics Protocol Server) and MAUS(Map Air Update Server). Presently, It is nearly impossible or very difficult for the company that are manufacturing and testing telematics device to develop and test telematics solution without connecting Telematics Service Provider, Service Provider, Contents Provider. And, it is very difficult to connect in TSP, CP, SP having the product to be developed. In this paper, we proposed virtual telematics service provider. The proposed Virtual Telematics Service Provider is to provide telematics services and functionalities by integrating telematics servers into TSP gateway virtually. In other words, VTSP is performs with the role of TSP, CP, SP. And the VTSP support integration of telematics servers, interfacing and monitoring between terminal and the integrated servers.

그리드는 지리적으로 흩어져 있는 이종의 자원들을 고속 네트워크로 연결하여 협업하기 위한 기반구조이다. 그리드 응용의 수행되기 위해서는 먼저 네트워크의 안정성과 신뢰성이 보장되어야 함으로 네트워크 자원들은 관리되어야 한다. GMA는 대규모 분산된 자원의 모니터링을 위한 효과적인 구조를 제안한다. 본 논문에서는 GMA를 기반으로 실제적이고 전체적인 네트워크 관리를 위한 웹 기반 그리드 네트워크 관리 시스템을 설계하였다. 그리드 네트워크 관리 시스템은 여러 분산된 관리 시스템을 스스로 유지시키면서 연결할 수 있어야 한다. LDAP 인증을 이용하여 시스템 접근에 대해 관리자 인증을 수행하여 그리드 네트워크 관리 시스템의 안정성을 보장한다.

Every ports is making great efforts to get competitiveness. It is progressing for the research on port model of new concept that connect port-related business to be developed from base running simple cargo processing to universal port that has economical efficiency and competitiveness, This research shows development way of Busan port that connect ship-repair industry which is port-related business. Development way is especially handled link between port and ship-repair industry field activation of high value-added ship as LNG etc.

According to 'Metropolitan Traffic Network Plan' announced in 2001, radial railways which connect Seoul with satellite cities around Seoul appear gradually. And followed by this, social demand for circular metropolitan railways that can connect the radial railways horizontally is increasing. But existing plans about circular metropolitan railways has limits to propose only passing cities of the railways. If there is no detailed guideline for circular metropolitan railways, the each railway for circular line will be constructed individually and then it will be not effective circular railways totally. Additionally that railway project will be easily interrupted by popular complaints. Therefore "The basic plan for circular metropolitan railways" is needful to guide a right direction for circular metropolitan railways. In this paper, rough track diagram of 'node' station for circular metropolitan railways is proposed. It is essential part of the basic plan. If the track diagram of a node is publicized in advance and individually lines of circular metropolitan railways is enforced to followed it, all lines will has rich circular functionality. Finally, effective circular metropolitan railways can be built.

This paper is about a system development which control and monitor a PLC of the remote-distance through the Internet using the web-browser. In general, the PLC uses its own communication protocol of PLC Manufacture. It is actually impossible to be used through the Internet, because the PLC communication protocol is basically developed to be suitable for short-distance. Therefore, what we need is a transformation system which can convert the PLC communication protocol into the form which can connect to the Internet. In that sense, this paper is that about remote-control method through the WWW ( World Wide Web ). This system have three characteristics. First, it is possible to connect the Internet directly irrespective of CPU, Operating system and browser. Second, it is easy for user to access and treat. Third, it needs only HTML to operate without java or plug-in expansion. In this paper, we will introduce the monitoring and control system of PLC on the Linux with the Apache web-server.

많은 기존의 E-러닝은 SCORM과 LMS를 연동하고 있다. 또한 U-러닝은 E-러닝의 하나의 트랜드로 연구되고 있다. 그러나 U-러닝에서 기존의 SCORM과 LMS를 연동하는 방안에 대해서는 매우 미흡하게 제시되고 있다. 본 연구는 기존의 SCORM과 LMS를 연동한 U-러닝 프레임워크를 제안하고자 한다. U-러닝에서 사용하는 각기 다른 모바일 기기의 특성을 반영하기 위하여 모바일 기기 변환모듈과 학습객체 재구성 모듈을 이용하였다. 특히 모바일 기기 정보는 모바일 기기 메타데이터를 사용하여 저장하고 관리하였다.

The 3' ends of most eukaryotic messenger RNAs must undergo a maturation step that includes an endonuc-leolytic cleavage followed by addition of a polyadenylate tail. While this reaction is catalyzed by the action of only two enzymes it is supported by an unexpectedly large number of proteins. This complexity reflects the necessity of coordinating this process with other nuclear events, and growing evidence indicates that even more factors than previously thought are necessary to connect 3' processing to additional cellular pathways. In this review we summarize the current understanding of the molecular machinery involved in this step of mRNA maturation, focusing on new core and auxiliary proteins that connect polyadenylation to splicing, DNA damage, transcription and cancer.

Bluetooth는 2.4G의 ISM 대역을 사용하며 저 전력, 적은 복잡성으로 Ad Hoc 망 형태에 기반을 둔 무선망을 구성하고 있으며, 현재 이동성을 고려한 무선형태의 망을 이루는 네트워크연구도 활발히 진행되어지고 있다. Bluetooth는 사용자들이 Bluetooth에 모두 정통하지 않아도 주위의 다른 디바이스에 의해 detect, connect, discover 서비스를 할 수 있게 설계되어 있다. 본 논문에서는 Bluetooth에서의 통신방법과 무선망에서의 동작 라우팅 알고리즘에 대해 분석하고져 한다.

In this paper, we have proposed Architecture Development methodology which can connect both operational view and system view. The Functional Architecture can connect both user and developer, and it is located between Activity analysis and System analysis. We suggest the new architecture methodology using the Functional Architecture and it provides effect to analyze the connection between user(military) and developer(enterprise) in Defence R&D and the new Architecture with the feedback analyze activity on a point of system view and the new architecture make the functional architecture.

The 3D display has been used in optical projection technology to connect twenty mini- projectors with seamless image tiling. In this way, we can improve the projected resolution by reducing each project screen and increase projected area by connect several mini-projectors. In this article, the illumination system uses the LED light source, non- telecentric structure and LCOS panel, and it's total length is less than 10 centimeter. It can build a seamless large display by tiling multiple projectors.
