산업이 발전함에 따라 지적재산권에 대한 가치는 점정 중요해지고 있고, 기업의 흥망성쇄를 결정짓는 가장 큰 요인중 하나로 자리잡고 있다. 엄청난 비용을 투자하여 사업화하고 있던 세계 굴지의 기업들도 경쟁회사의 핵심특허 단 몇 건만으로 순식간에 몰락하는 경우도 발생하고 있다. 이제 지적재산권은 살아남기 위한 유일한 방어수단이자 공격수단이 되었다. 이와 같은 급박한 상황하에서 각 기업은 경쟁회사의 지적재산권을 분석하고, 이를 통해 자사의 연구개발 전략을 수립하기 위해 노력하고 있다. 그러나 이와 같은 분석작업은 다수의 전문가 일지라도 상당한 시일이 소요되는 방대한 작업이며, 이를 자동으로 실행하기 위해 많은 소프트웨어 회사들은 Clinent base 특허분석용 툴과 Web base site를 개발하여 서비스를 하고 있다. 그러나 이들 종래의 특허분석용 툴과 Web site들은 특허에대한 정량분석 정보와 정성분석 정보를 제공하지만 해당 특허가 기술분야에서 얼마나 영향력을 미치는 객관적으로 제시를 하지 못하고 있다. 본 논문에서는 개술 개발시 해당 분야의 특허 기술의 흐름을 빠르게 파악하고 동 기술 분야에서 영향력이 있는 특허의 랭킹을 제시하여 기술 개발시의 위험성을 줄이고자 하는데 그 목적이 있다. 이에 특허 출원시 인용했던 선행특허들의 인용 관계를 분석하여 특허간 연관관계를 규명하고, 각 기술 분야에서 영향력이 높은 특허를 찾는 방법과 시스템을 제시하고자 한다.

The generalization of Internet use has been spreaded all over the world and impacted company to introduce intranet and extranet for their operation which dealt with electronic commerce. For these reason, endeavor of implementation of web site system is promotioned and enhanced the possibility of adaptation range for the view of company. Dramatic competition which company faced with the use of internet and request from all over the world made company brought company to various and different type of level. It is necessary to develop website system with experty knowledge to satisfy customer needs. To deal with this situation, works from the level of government should proposed to spread whole country business which propelled through kyungnam mechanic industry information promotion center. With strategic proposal concerning district characteristics to adapt electronic commerce successfully, information promotion should performed. Support of government is needed continuously to realize infra of ASP composed of 4,877 mechanic industry company. It might be possible to deal with international rapid change with cooperation of company and government related department.

This paper summarized the results of a full-scale cyclic seismic testing on four reduced beam section (RBS) steel moment connections. Specifically, these tests addressed a bolted web versus a welded web connection and strong versus medium panel zone (PZ) strength as key test variables. Specimens with medium PZ strength were designed to promote balanced energy dissipation from both PZ and RBS regions, in order to reduce the requirement for expensive doubler plates. Both strong and medium PZ specimens with welded web connection were able to provide sufficient connection rotation capacity required of special moment-resisting frames. On the other hand, specimens with bolted web connection performed poorly due to premature brittle fracture of the beam flange at the weld access hole. Unlike the case of web-welded specimens, specimens with cheaper bolted web connection could not transfer the actual plastic moment of the original (or unreduced) beam section to the column. No fracture occurred within the beam groove welds of any connection in this testing program. If fracture within the beam flange groove weld is avoided by using quality welding procedure as in this study, the fracture issue tends to move into the beam flange base metal at the weld access hole. Supporting analytical study was also conducted in order to understand the observed base metal fracture from the engineering mechanics perspective.

With the growth of internet shopping malls, there is increasing interest in comparison shopping mall. However most comparison sites compare only book prices by collecting simple XML data and do not provide .the exact comparison Including precise shipping costs. Shipping costs vary depending on each customer's address, the delivery method, and the category of selected goods, so rule based system is required in order to calculate exact shipping costs. Therefore, we designed and implemented comparison shopping mall which compares not only book prices but also shipping costs using rule based inference. By adopting the extensible Rule Markup language (XRML) approach, we proposed the methodology of extracting delivery rules from Web pages of each shopping mall. The XRML approach can facilitate nearly automatic rule extraction from Web pages and consistency maintenance between Web pages and rule base. We developed a ConsiderD system which applies our rule acquisition methodology based on XRML. The objective of the ConsiderD system is to compare the exact total cost of books including the delivery cost over Amazon.com, BarnesandNoble.com, and Powells.com. With this prototype, we conducted an experiment to show the potential of automatic rule acquisition from Web pages and illustrate the effect of delivery cost.

This study discussed on production, procedures of collection, accessibility, copyright of archival records for designing oral history archive information system, and aimed to suggest practical standards by developing guidelines for evaluation and building of web oral history archives. For this, based on evaluation framework, guidelines for evaluation designed by researchers were applied to five domestic and foreign web oral history archives as case study analysis. Base on the results of the analysis, some possible suggestions were made for building successful web oral history archive information system in Korea.

In this paper, we constructed Embedded web-server to be monitored and controlled for intelligent vehicle on the base of embedded system and Zigbee wireless communication. By interfacing main controller and embedded system with ECU including every information of vehicle, it is possible to monitor the cruising information of vehicle, and sensor signal added to inside and outside of vehicle is transferred to embedded system through Zigbee communication. Web-server is constructed using embedded system, that's why the access to vehicle is possible using PC or mobile instrument, and the real-time check and control of vehicle is possible as well.

This paper proposes a technique improving performance using word senses and user feedback in web information retrieval, compared with the retrieval based on ambiguous user query and index. Disambiguation using word senses is very important processing for improving performance by eliminating the irrelevant pages from the result. According to semantic categories of nouns which are used as index for retrieval, we build the word sense knowledge-base and categorize the web pages. It can improve the performance of retrieval system with user feedback deciding the query sense and information seeking behavior to web pages.

To support business service interoperability, it is necessary to extend WSDL and develop Business Service Document(BSD) to contain various business service informations. W3C delegates extension of WSDL to the user groups for their usages and objectives. Therefore this article defines BSD, which is extended version of WSDL. This article also presents Business Web Service Framework(BWSF), which supports business service interoperability and uses BSD. BSD Creator is developed to create correct, valid and well-formed BSD which is core component of BWSF. This article is expected to be used as base concepts for industrial adoption of business service interoperability architecture, and it is also expected to contribute for revitalize business service interoperability.

Roll-to-roll based manufacturing plays an important role in producing devices at high speed with lower production cost in printed electronics and publishing industry. Web lateral control is one of the most important factors in improving the quality of product and contributes a considerable point in making devices at micrometer-level accuracy. In recent years, most algorithms proposed for web lateral control base on the Shelton‘s model for designing the feedback control system using the PI controller. Experimental results showed that the existing models do not fully describe the characteristics of the lateral dynamics for some typical operating conditions and so result in poor control algorithms. In this paper, a new lateral control algorithm is proposed for web lateral control system based on back-stepping approach. The outcome of this study proves the reliability throughout simulation results in Matlab/Simulink and comparison with the algorithms based on the existing results.
